To analyze the transmission characteristics of newly reported HIV-infected students aged ≥18 years in Nanjing City from 2016 to 2022 and provide evidence for AIDS publicity and intervention among young students. The pol region sequences of newly reported HIV-infected students and non-student HIV-infected individuals in Nanjing City from 2016 to 2022 were collected, and the BLAST tool was used to search the published global non-Nanjing reported HIV infection sequences in the LANL HIV database. The basic molecular transmission network and regional molecular transmission network were constructed using the HIV-TRACE in a pairwise genetic distance threshold of 1.0%. 332 sequences of infected students aged≥18 years in Nanjing City, 1 904 sequences of non-student-infected individuals in Nanjing City and 1 698 non-Nanjing-infected individuals were obtained. Among the 332 infected students, the main route of infection was homosexual (96.39%), and the subtypes were CRF01_AE (37.95%), CRF07_BC (37.65%) and CRF105_0107 (10.24%). There were 890 sequences in the regional molecular transmission network, of which 21.80% were infected students in Nanjing City, 39.89% were non-student-infected individuals in Nanjing City, and 38.31% were non-Nanjing-infected individuals. In the CRF105_0107 transmission cluster, non-student-infected individuals from Nanjing accounted for 66.95% (81/121), while in the CRF07_BC transmission cluster, non-Nanjing-infected individuals accounted for 56.66% (200/353). There were 1 644 edges connected to infected students within the regional molecular transmission network, with local transmission accounting for 64.72% and regional transmission accounting for 35.28%. Regional transmission was mainly in Guangdong Province (19.83%) and other cities in Jiangsu Province (4.50%). The HIV-1 subtypes of newly reported HIV-infected students aged≥18 years in Nanjing City are mainly CRF01_AE, CRF07_BC and CRF105_0107, with local transmission as the main transmission characteristics. There is transmission between students and non-students.

Objective: To analyze the temporal trends of the incidence rate of tuberculosis (TB) in Shaanxi Province and provide a reference for WHO to control the prevalence of TB effectively. Methods: Joinpoint regression was used to analyze the trend of the incidence rate of TB in Shaanxi Province from 2004 to 2022, and the seasonal autoregressive moving average model was used to forecast the incidence rate of TB in Shaanxi Province to 2030. Results: The incidence rate of TB in Shaanxi Province decreased from 90.896/100 000 in 2004 to 35.364/100 000 in 2022, showing a general downward trend (AAPC=-7.72%, P <0.001). From 2014 to 2019, the reduction trend slowed down (APC=-0.69%, P =0.814), of which the largest decline occurred from 2019 to 2022 (APC=-13.26%, P =0.010). The predicted incidence rate of TB in Shaanxi Province from 2020 to 2022 was higher than the reported incidence rate, with the expected incidence rate of 51.342/100 000 in 2022 and 43.468/100 000 in 2030. Conclusion: The incidence rate of TB in Shaanxi Province shows a downward trend from 2004 to 2022, but the decline has shrunk in recent years. It is predicted that the downward trend will continue to slow down by 2030.

Objective: To describe the epidemiological characteristics and trends of leukemia incidence in Qidong between 1972 and 2021, and provide guidelines for prevention and control measures and strategies. Methods: The cancer registry data was collected and analyzed on leukemia incidence during 1972-2021 in Qidong by sex, age and time. Crude incidence rate (CR), China age-standardized rate (ASRC), world age-standardized rate (ASRW), and average annual change percentage (AAPC) was calculated by Joinpoint software. Age-period-cohort (APC) model was used to analyze the influence of age, period and birth cohort on the changes in the incidence trend of leukemia patients. Results: From 1972 to 2021, there were 2 948 patients with leukemia in Qidong, accounting for 2.00% of all cancer new cases, CR of leukemia was 5.26/10 5 , ASRC was 4.34/10 5 , ASRW was 4.35/10 5 . The truncated incidence of 35-64 years old was 5.29/10 5 , the cumulative incidence rate between the ages of 0 and 74 years old was 0.40%, the cumulative risk was 0.40%. There were 1 608 male patients, the CR, ASRC, and the ASRW were 5.81/10 5 , 4.88/10 5 and 4.85/10 5 . The number of female patients were 1 340, and the CR, ASRC, and the ASRW were 4.71/10 5 , 3.86/10 5 and 3.91/10 5 , respectively. Temporal trends indicated significant upward trends in ASRC among both gender, males and females with AAPC values of 1.41% ( P ＜0.001), 1.15% ( P ＜0.001), and 1.73% ( P ＜0.001), respectively. The results of the APC model showed that the average net drift value of leukemia incidence in all age groups was 1.57% (95% CI , 1.24%-1.89%), and the highest value of local drift was 3.20% (95% CI , 1.63%-4.78%) in the 80~ years old group. The incidence of leukemia increased with age. With the passage of time, the risk of leukemia incidence increased gradually compared with the rate ratio of leukemia incidence (risk ratio [ RR ], 1.00) in 1992-1996, the RR of leukemia incidence increased from 0.70 during 1972-1976 to 1.57 during 2017-2021. The later the cohort was born, the greater the risk of leukemia incidence compared with the relative risk of leukemia incidence ( RR , 1.00) in 1952-1956 cohort, the RR of leukemia incidence increased from 0.24 in the 1892-1896 cohort to 2.73 in the 2017-2021 cohort. Conclusions: The incidence of the leukemia has presented a rising trend in the past fifty years. Leukemia incidence increased with age, and the period and cohort effects on the risk of incidence increase. Further research is needed to investigate the risk factors related to leukemia.

The sustainable development of sports facilities and their integration with the ecological environment are crucial in addressing global environmental challenges. This study examines the coupling coordination between sports facilities and the ecological environment in nine prefecture-level cities in Fujian Province, China, from 2013 to 2020, within the framework of China's "Dual Carbon" strategy. Using a multidisciplinary approach that integrates economics, sociology, and geography, the study employs the entropy method and coupling coordination models to analyze the temporal evolution and spatial distribution of the coupling coordination between sports facilities and the ecological environment. The findings reveal that the overall trend of coupling coordination is positive, with the degree of coordination improving over time from severe imbalance in 2013 to high-quality coordination by 2020. Economic factors, such as per capita GDP, positively influence the coupling coordination, while factors like population density and regional GDP have a negative impact. Coastal cities, such as Xiamen and Zhangzhou, demonstrate stronger regional correlations and play a critical role in improving the overall coupling level of the province. This research provides several recommendations for promoting orderly and optimal development, considering the distinct characteristics of sports facilities and the ecological environment., (© 2024.

Aesthetic education, conveyed through public art courses, serves as a vital form of humanistic literacy education. It represents an effective approach to fostering innovative and creative thinking among college students. In order to effectively analyze the aesthetic education work of 46 universities, an aesthetic education index evaluation system is constructed, involving indicators including faculty strength, curriculum setting, teaching management, artistic practice, and teaching support. The secondary indicators corresponding to the five indicators are statistically analyzed, and a comprehensive evaluation analysis of the current development status of aesthetic education in 46 universities in Anhui Province is conducted by combining theoretical analysis with empirical analysis. Based on principal component analysis, an integrated evaluation model for the development of aesthetic education in universities in Anhui Province is further constructed. The model designed quantifies the influence weight of each aesthetic education index on the development of aesthetic education in Anhui Province, and forges a theoretical basis for determining the precursors of rapid development of aesthetic education in Anhui Province. Additionally, a novel approach is introduced to gauge the progression of aesthetic education within universities in Anhui Province, considering the dispersion of aesthetic education index data across the province. The comprehensive evaluation model for the development of aesthetic education in Anhui Province exhibits an overall declining trend. Hence, it is suggested to utilize the maximum value of the first derivative of the comprehensive evaluation model as an indicator of the imminent rapid development of aesthetic education in Anhui Province. On this basis, the probability equation of sustainable development of aesthetic education in Anhui Province is defined. Overall, the research results lay a theoretical foundation for the development of aesthetic education in Anhui Province., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Xu et al.

Objective To assess the influences of self-and interviewer-administered methods on the scores of anxiety and depression questionnaires among the patients with sports injuries.Methods A total of 532 participants with sports injuries treated in the Sports Medicine Center of West China Hospital,Sichuan University from November 2022 to May 2023 were included.They were randomly assigned to either the interviewer-administered group ( n =270) or the self-administered group ( n =262) to complete the generalized anxiety disorder (GAD-7) and the patient health questionnaire (PHQ-9) scales.The total scores and prevalence rates of anxiety and depression were compared between the two groups.Results There was no statistically significant difference in gender,occupation,or surgical site between the two groups (all P >0.05).The self-administered group had higher scores of GAD-7 and PHQ-9 scales than the interviewer-administered group ( P <0.001, P <0.001).A greater proportion of participants in the self-administered group than in the interview-administered group met the criteria for mild to moderate anxiety and depression ( P <0.001, P =0.002).The prevalence rates of moderate to severe anxiety (GAD-7≥10) and depression (PHQ-9≥10) showed no statistically significant difference between the two groups ( P =0.761, P =0.086).Conclusion This study demonstrates that the participants in the self-administered group are more likely to report mild to moderate symptoms of anxiety and depression than those in the interviewer-administered group.

Objective: Using Meta-analysis to evaluate the vaccine effectiveness of 13-valent pneumococcal conjugate vaccine (PCV13) against invasive Streptococcus pneumoniae disease (IPD) caused by serotype 19A in children <5 years old. Methods: "Streptococcus pneumoniae infection""invasive pneumococcal disease""13-valent pneumococcal polysaccharide conjugate vaccine""PCV13""effectiveness""infant""child" and related terms were searched from China National Knowledge Infrastructure (CNKI), WANFANG DATA, PubMed, SCOPUS and Web of science with no limited on language, region and research institution. The retrieval time was limited from January 2010 to February 2023 and cohort study, case-control study and randomized controlled trial were included. Data were extracted from eligible studies by two independent reviewers, and after study quality assessment by NOS scale, Meta-analysis was completed using Stata 16.0 software. Results: A total of 2 340 related literatures were searched, and 10 literatures were finally included, including 5 case-control studies and 5 indirect cohort studies, which showed good literature quality. The vaccine effectiveness against serotype 19A IPD of PCV13 in children was 83.91% (95% CI : 78.92%-88.89%), and the subgroup analysis ( P =0.240) showed there was no significant difference among the case-control study (VE=87.34%, 95% CI :79.74%-94.94%) and the indirect cohort study (VE=81.30%, 95% CI :74.69%-87.92%). The funnel plot and Egger test suggested that the possibility of publication bias was small. Conclusion: The present evidence indicates that PCV13 has a good vaccine effectiveness against serotype 19A IPD in children, and it is recommended to further increase the vaccination rate of PCV13 to reduce the disease burden of IPD in children <5 years old.

Autoimmune eye diseases (AEDs), a collection of autoimmune inflammatory ocular conditions resulting from the dysregulation of immune system at the ocular level, can target both intraocular and periorbital structures leading to severe visual deficit and blindness globally. The roles of air pollution and meteorological factors in the initiation and progression of AEDs have been increasingly attractive, among which the systemic and local mechanisms are both involved in. Exposure to excessive air pollution and extreme meteorological conditions including PM 2.5 /PM 0.1 , environmental tobacco smoke, insufficient sunshine, and high temperature, etc., can disturb Th17/Treg balance, regulate macrophage polarization, activate neutrophils, induce systemic inflammation and oxidative stress, decrease retinal blood flow, promote tissue fibrosis, activate sympathetic nervous system, adversely affect nutrients synthetization, as well as induce heat stress, therefore may together deteriorate AEDs. The crosstalk among inflammation, oxidative stress and dysregulated immune system appeared to be prominent. In the present review, we will concern and summarize the potential mechanisms underlying linkages of air pollution and meteorological factors to ocular autoimmune and inflammatory responses. Moreover, we concentrate on the specific roles of air pollutants and meteorological factors in several major AEDs including uveitis, Graves' ophthalmopathy (GO), ocular allergic disease (OAD), glaucoma, diabetic retinopathy (DR), etc., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Inc.

Background: As the complexity and diversity of the tumor immune microenvironment (TIME) are becoming better understood, burgeoning research has progressed in this field. However, there is a scarcity of literature specifically focused on the bibliometric analysis of this topic. This study sought to investigate the development pattern of TIME-related research from 2006 to September 14, 2022, from a bibliometric perspective., Methods: We acquired both articles and reviews related to TIME from the Web of Science Core Collection (WoSCC) (retrieved on September 14, 2022). R package "Bibliometrix" was used to calculate the basic bibliometric features, present the collaborative conditions of countries and authors, and generate a three-field plot to show the relationships among authors, affiliations, and keywords. VOSviewer was utilized for co-authorship analysis of country and institution and keyword co-occurrence analysis. CiteSpace was used for citation burst analysis of keywords and cited references. In addition, Microsoft Office Excel 2019 was used to develop an exponential model to fit the cumulative publication numbers., Results: A total of 2545 publications on TIME were included, and the annual publication trend exhibited a significant increase over time. China and Fudan University were the most productive country and institution, with the highest number of publications of 1495 and 396, respectively. Frontiers in Oncology held the highest number of publications. A number of authors were recognized as the main contributors in this field. The clustering analysis revealed six clusters of keywords that highlighted the research hot spots in the fields of basic medical research, immunotherapy, and various cancer types separately., Conclusions: This research analyzed 16 years of TIME-related research and sketched out a basic knowledge framework that includes publications, countries, journals, authors, institutions, and keywords. The finding revealed that the current research hot spots of the TIME domain lie in "TIME and cancer prognosis", "cancer immunotherapy", and "immune checkpoint". Our researchers identified the following areas: "immune checkpoint-based immunotherapy", "precise immunotherapy" and "immunocyte pattern", which may emerge as frontiers and focal points in the upcoming years, offering valuable avenues for further exploration., (© 2023.

Objective: This study aims to estimate the cost-effectiveness of the combined chemotherapy regimen containing Bedaquiline (BR) and the conventional treatment regimen (CR, not containing Bedaquiline) for the treatment of adults with multidrug-resistant tuberculosis (MDR-TB) in China., Methods: A combination of a decision tree and a Markov model was developed to estimate the cost and effects of MDR patients in BR and CR within ten years. The model parameter data were synthesized from the literature, the national TB surveillance information system, and consultation with experts. The incremental cost-effectiveness ratio (ICER) of BR vs . CR was determined., Results: BR ( vs . CR) had a higher sputum culture conversion rate and cure rate and prevented many premature deaths (decreased by 12.8%), thereby obtaining more quality-adjusted life years (QALYs) (increased by 2.31 years). The per capita cost in BR was as high as 138,000 yuan, roughly double that of CR. The ICER for BR was 33,700 yuan/QALY, which was lower than China's 1× per capita Gross Domestic Product (GDP) in 2020 (72,400 yuan)., Conclusion: BR is shown to be cost effective. When the unit price of Bedaquiline reaches or falls below 57.21 yuan per unit, BR is expected to be the dominant strategy in China over CR., (Copyright © 2023 The Editorial Board of Biomedical and Environmental Sciences.

Objective: To analyze the incidence and survival rate of liver cancer cases in the entire population in the Qidong region from 1972 to 2019, so as to provide a basis for prognosis evaluation, prevention, and treatment. Methods: The observed survival rate (OSR) and relative survival rate (RSR) of 34 805 cases of liver cancer in the entire Qidong region population from 1972 to 2019 were calculated using Hakulinen's method with SURV3.01 software. Hakulinen's likelihood ratio test was used for statistical analysis. Age-standardized relative survival (ARS) was calculated using the International Cancer Survival Standard. The Joinpoint regression analysis was performed with Joinpoint 4.7.0.0 software to calculate the average annual percentage change (AAPC) of the liver cancer survival rate. Results: 1-ASR increased from 13.80% in 1972-1977 to 50.20% in 2014-2019, while 5-ASR increased from 1.27% in 1972-1977 to 27.64% in 2014-2019. The upward trend of RSR over eight periods was statistically significant ( χ (2) = 3045.29, P < 0.001). Among them, male 5-ASR was 0.90%, 1.80%, 2.33%, 4.92%, 5.43%, 7.05%, 10.78%, and 27.78%, and female 5-ASR was 2.33%, 1.51%, 3.35%, 3.92%, 3.84%, 7.18%, 11.45%, and 29.84%, respectively. There was a statistically significant difference in RSR between males and females ( χ (2) = 45.68, P < 0.001). The 5-RSR for each age group of 25-34 years old, 35-44 years old, 45-54 years old, 55-64 years old, 65-74 years old, and 75 years old were 4.92%, 5.29%, 8.17%, 11.70%, 11.63%, and 9.60%, respectively. There were statistically significant differences in RSR among different age groups ( χ (2) = 501.29, P < 0.001). The AAPC in Qidong region from 1972 to 2019 for 1-ARS, 3-ASR, and 5-ARS were 5.26% ( t = 12.35, P < 0.001), 8.10% ( t = 15.99, P < 0.001), and 8.96 % ( t = 16.06, P < 0.001), respectively. The upward trend was statistically significant in all cases. The AAPC of 5-ARS was 9.82% in males ( t = 14.14, P < 0.001), and 8.79% in females ( t = 11.48, P < 0.001), and the upward trend was statistically significant in both. The AAPC of 25-34 years old, 35-44 years old, 45-54 years old, 55-64 years old, 65-74 years old, and 75 years old were 5.37% ( t = 5.26, P = 0.002), 5.22% ( t = 5.66, P = 0.001), 7.20% ( t = 6.88, P < 0.001), 10.00% ( t = 12.58, P < 0.001), 9.96% ( t = 7.34, P < 0.001) and 8.83% ( t = 3.51, P = 0.013), and the upward trend was statistically significant. Conclusion: The overall survival rate of registered cases of liver cancer in the Qidong region's entire population has greatly improved, but there is still much room for improvement. Hence, constant attention should be paid to the study on preventing and treating liver cancer.

Objectives: The aims of the study were to assess the management of low-density lipoprotein cholesterol (LDL-C) and the goal achievement, as well as to investigate the association between baseline LDL-C level, lipid-lowering treatment (LLT), and stroke recurrence in patients with ischaemic stroke or transient ischaemic attack (TIA)., Design: Our study was a post hoc analysis of the Third China National Stroke Registry (CNSR-III)., Setting: We derived data from the CNSR-III - a nationwide clinical registry of ischaemic stroke and TIA based on 201 participating hospitals in mainland China., Participants: 15,166 patients were included in this study with demographic characteristics, etiology, imaging, and biological markers from August 2015 to March 2018., Primary and Secondary Outcome Measures: The primary outcome was a new stroke, LDL-C goal (LDL-C<1.8mmol/L and LDL-C<1.4mmol/L, respectively) achievement rates, and LLT compliance within 3, 6, and 12 months. The secondary outcomes included major adverse cardiovascular events (MACE) and all caused death at 3 and 12 months., Results: Among the 15,166 patients, over 90% of patients received LLT during hospitalization and 2 weeks after discharge; the LLT compliance was 84.5% at 3 months, 75.6% at 6 months, and 64.8% at 12 months. At 12 months, LDL-C goal achievement rate for 1.8mmol/L and 1.4mmol/L was 35.4% and 17.6%, respectively. LLT at discharge was associated with reduced risk of ischemic stroke recurrence (HR=0.69, 95% CI: 0.48-0.99, p=0.04) at 3 months. The rate of LDL-C reduction from baseline to 3-month follow-up was not associated with a reduced risk of stroke recurrence or major adverse cardiovascular events (MACE) at 12 months. Patients with baseline LDL-C ≤1.4mmol/L had a numerically lower risk of stroke, ischemic stroke and MACE at both 3 months and 12 months., Conclusions: The LDL-C goal achievement rate has increased mildly in the stroke and TIA population in mainland China. Lowered baseline LDL-C level was significantly associated with a decreased short- and long-term risk of ischemic stroke among stroke and TIA patients. LDL-C<1.4mmol/L might be a safe standard for this population., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023. Re-use permitted under CC BY-NC.

Some collections from northern China are proposed as the new genus and species Villoboletus persicinus based on morphological assessments and molecular phylogenetic evidence. It is circumscribed by the pink pileus, white context turning pale blue to bule when exposed, yellow hymenophore surface turning blue when bruised, stipe covered with plenty of flocculent hairs, ellipsoid-fusiform to subfusiform smooth basidiospores, and the presence of hymenial cystidia. Phylogenetic analyses inferred from four gene fragments (28S, tef1, rpb1 , and rpb2 ) revealed a distinct position of this new genus in Boletaceae, but no place to accommodate it at subfamily rank.

Objective: The survival of colorectal cancer in Qidong City, Jiangsu Province from 1972 to 2016 was analyzed to provide a basis for the evaluation of prognosis and the formulation of prevention and control measures. Methods: Colorectal cancer data were obtained from the Qidong Cancer Registration and Reporting System, and the follow-up was up to December 31, 2021. The observed survival rate (OSR) and relative survival rate (RSR) were calculated by SURV 3.01 software, and the trend test was performed by Hakulinen's likelihood ratio test. The Joinpoint regression model was used to calculate the average annual percentage change (AAPC) of survival, and the ARIMA model was used to predict the trend of colorectal cancer survival. Results: There were 8 637 new cases of colorectal cancer in Qidong from 1972 to 2016. Dividing 1972-2016 into 9 periods at 5-year intervals, the 5-year OSR from 1972-1976 to 2012-2016 increased from 21.86% to 48.86%, and the 5-year RSR increased from 26.45% to 59.91%. The increasing trend of RSR was statistically significant ( χ (2)=587.47, P <0.001). From 1972 to 2016, the survival rates of colorectal cancer in different sexes in Qidong were similar, and the 5-year RSR was 44.63% for men and 44.07% for women. Since the 1990s, the 5-year OSR and RSR for men have been lower than those for women. From 1972 to 2016, the 5-year RSR of colorectal cancer in Qidong was significantly improved in the 65-74 and ≥75-year-old groups, but the survival rate of the ≥75-year-old group was still the lowest (36.78%), followed by the 35-44-year-old group ( 43.04%). The time trend showed that the overall AAPC of colorectal cancer 5-year RSR in Qidong from 1972 to 2016 was 2.50% ( t =16.45, P <0.001). The upward trend of different sexes was consistent, and the increase was greater in women (AAPC for males=2.18%, AAPC for females=2.54%, both P <0.05). The 5-year RSR of colorectal cancer in each age group showed an upward trend, and the AAPCs of the 35-44, 45-54, 55-64, 65-74, and ≥75-year-old groups were 1.54%, 1.83%, 2.00%, 3.51% and 4.35%, respectively (all P <0.05). The prediction results of colorectal cancer survival rate showed that the 5-year RSR of colorectal cancer in Qidong will increase to 71.62% by 2026. Conclusions: The overall survival rate of colorectal cancer patients in Qidong has been greatly improved, but there is still room for improvement. We should continue to pay attention to the early diagnosis and early treatment of colorectal cancer.

Background: Despite providing clinical benefit, immune checkpoint inhibitors (ICIs) can cause immune-related adverse events (irAEs) in a number of patients. This study explored the development pattern in irAEs research from a bibliometric perspective., Methods: We obtained articles and reviews related to irAEs from the Web of Science Core Collection (WoSCC) (retrieved on September 13, 2022). Using the R package "Bibliometrix", the main bibliometric features were calculated, and a three-filed plot was generated to show the relationship between authors, institutions, and topics. VOSviewer was used for co-authorship and keyword co-occurrence analysis and visualization. CiteSpace was used to detect burst references and keywords., Results: A total of 3995 publications on irAEs were included. The United States (US), Japan, and China had the highest publications. The Journal for ImmunoTherapy of Cancer had the highest number of publications. In addition to "immune-related adverse events", "immune checkpoint inhibitors", "immunotherapy", and "nivolumab" were the most frequently used keywords., Conclusions: A bibliometric analysis of 17 years of irAEs research was conducted to map a basic knowledge structure including countries, institutions, authors, journals, and publications. The findings provided a comprehensive perspective on the broad future of this research area., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Jiang, Liu, Zhang, Sang, Xu and Lu.)

Objectives: To study the features of unintentional injury in children under the impact of coronavirus disease 2019 (COVID-19)., Methods: A retrospective analysis was performed on the medical data of 2 526 children with unintentional injury in Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from July 2019 to June 2022. The study period was divided into 5 stages: before the epidemic (July to December, 2019), the Wuhan epidemic period (January to April, 2020), the epidemic remission period in China (May 2020 to February 2022), the Shanghai epidemic period (March to May, 2022), and the epidemic remission period in Shanghai (June 2022). The incidences of unintentional injury in children at different time stages and different ages were compared. A questionnaire survey was conducted on 107 children of the 2 526 children to explore the features of unintentional injury., Results: There were significant differences in gender composition, age, age distribution and proportion of many types of unintentional injuries among the five time stages ( P <0.05). There was a reduction in the number of children who attended the emergency department due to unintentional injury during the Wuhan epidemic and the Shanghai epidemic. The proportion of children with trauma-related unintentional injuries in each stage reached more than 50%, and the proportion of children with trauma-related unintentional injuries reached 63.9% and 82.0%, respectively during the Wuhan epidemic and the Shanghai epidemic. Most children suffering from unintentional injury were mainly school-aged and preschool children (1 823 children, 72.17%). Compared with the same period of Shanghai epidemic in 2021, the age of children with unintentional injury was younger (median 7 years vs 11 years), and the proportion of children with trauma-related unintentional injuries increased (97% vs 69%) during the Shanghai epidemic ( P <0.05)., Conclusions: Under the COVID-19 epidemic, there is a reduction in the number of children with unintentional injury, while there is an increase in the proportion of children with trauma-related unintentional injuries. Unintentional injury is more common among school-aged and preschool children.

The unreasonable use of antibiotics and the transmission of antibiotic resistance genes (ARGs) induced by antibiotics have led to a large number of ARGs entered the water environment, which seriously threatened human health and environmental safety. The estuarine aquatic environment connects with inland rivers and sea and is frequently influenced by human activities. This study aims to reveal the occurrences and abundances of ARGs and bacterial community composition by high-throughput quantitative PCR including 296 primers and high-throughput sequencing in the tide rising and ebbing of surface water in the Yongjiang Estuary, China. The results showed that there were a large number of ARGs and mobile genetic elements (MGEs) detected in the rising tide and ebb tide water bodies. The numbers of detected ARGs in each sample at rising and ebb tide ranged from 16 to 77 and 61 to 88, respectively, and the absolute abundance ranges were 1.69 × 10 4 -1.69 × 10 9 copies/L and 3.18 × 10 3 -2.57 × 10 9 copies/L, respectively. Obvious tidal distribution characteristics of ARGs were showed. Most of ARGs conferred resistance to multidrug, aminoglycosides and sulfanilamides. Proteobacteria, Actinobacteria and Bacteroidetes were the dominantly bacterial phylum in the Yongjiang Estuary. Network analysis results indicated that multi-genera were identified as possible ARGs hosts, and they carried more than two types of ARGs genes. Partial least squares path modeling further revealed that MGEs and bacterial community composition were the most important driving factors. The results of the study can provide the corresponding scientific basis for the diffusion and control of ARGs in estuaries., (Copyright © 2022 Elsevier Inc. All rights reserved.)

A new genus and new species of freshwater crab, Jianghuaimon dabiense gen. et sp. nov., is described from Anhui and Hubei Provinces of China based on morphology and mitochondrial 16S rDNA sequences. Externally, the new genus resembles several other potamid genera from China. However, its combination of carapace, male pleon, third maxilliped, and uniquely structured male first gonopod distinguish it from the others. Phylogenetic analysis using the 16S gene supports the new genus new species and shows that it, together with morphologically similar Neilupotamon and Bottapotamon, form a distinct clade.

Objective: To study the distribution characteristics of thalassemia genotype in Han Population in Sanya of Hainan Province., Methods: Gap PCR and reverse dot hybridization were used to detect and analyze the thalassemia gene in 572 suspected thalassemia carriers of Han Population in Sanya., Results: Among the 572 Han Population in Sanya, 271 cases of thalassemia gene abnormality were detected, among which 161 cases were founded to be carriers of α-thalassemia gene. A total of 9 genotypes were detected, in the following order of the detection rate was －－ SEA /αα，－α 3.7 /αα，－α 4.2 /αα，－－ SEA /－α 3.7 ，－－ SEA /－α 4.2 ，－α 4.2 /－α 4.2 ，－α 3.7 /－α 4.2 ，－α 3.7 /－α 3.7 ，－－ SEA /－－ SEA . Among them, the deletion type (－－ SEA /αα) in southeast Asia was the most common, accounting for 66 cases. 99 cases of β-thalassemia were detected, there were 7 genotypes, all of which were heterozygous. The order of the detection rate was CD41-42/βN, IVS-II-654/βN, CD17/βN, CD71-72/βN, -28/βN, －29/βN, CD27-28/βN. Among them, CD41-42/βN was the most common, accounting for 51 cases. In addition, 11 cases of combined α and β thalassemia were detected. Five kinds of genotypes were checked out, the order of detection rate was －α 3.7 /αα composite CD41-42/βN, －－ SEA /αα composite IVS-II-654/βN, －α 4.2 /－α 4.2 composite CD41-42/βN, －α 4.2 /αα composite －29/βN , －－ SEA / －α 4.2 composite CD41-42/βN., Conclusion: Han Population in Sanya of Hainan Province is a high-risk population of thalassemia, the genotype characteristics are different from other areas with high incidence of thalassemia in China. The main type of α-thalassemia is the deficiency mutation of southeast Asia, while CD41-42 heterozygous mutation is the main type of β-thalassemia.

Background: Although numerous studies have suggested that elevated N-terminal pro-brain natriuretic peptide (NT-proBNP) is positively correlated with cardiovascular events, especially the heart failure and heart failure-related death (HFRD), evidence of the association between NT-proBNP and the adverse outcomes of hypertrophic cardiomyopathy (HCM) is still relatively limited. The present study was performed to evaluate the relationship between NT-proBNP and outcomes in patients with HCM., Methods: Observational cohort methodology was used in the present study, and a total of 227 patients were included. And the patients were followed for 44.97 ± 16.37 months. Patients were categorized into three groups according to these NT-proBNP tertiles: first tertile (≤910 pg/ml, n=68), second tertile (913-2141 pg/ml, n=68), and third tertile (≥2151 pg/ml, n=69). The adverse outcomes of the present study were all-cause death (ACD) and cardiac death (CD)., Results: According to the risk category of NT-proBNP, the incidence of ACD (P=0.005) and CD (P=0.032) among the three groups showed significant differences. Multivariate Cox regression analysis suggested that the ACD and CD in the third tertile have 7.022 folds (hazard risk [HR] = 7.022 [95% confidence interval [CI]: 1.397-35.282], P=0.018) and 7.129 folds (HR = 7.129 [95% CI: 1.329-38.237], P=0.022) increased risks as compared with those in the first tertile. Kaplan-Meier survival analyses showed that the cumulative risks of ACD and CD in patients with HCM tended to increase., Conclusion: The present study indicated NT-proBNP was a novel biomarker suitable for predicting adverse prognosis in patients with HCM, which may be used for early recognition and risk stratification., (© 2022 The Author(s).)

Objective: To describe the epidemic characteristics of stomach cancer mortality in Qidong between 1972 and 2016. Methods: The cancer registry data of stomach cancer death and population during 1972-2016 in Qidong was collected. The mortality of crude rate (CR), China age-standardized rate (CASR), world age-standardized rate (WASR), 35-64 years truncated rate, 0-74 years cumulative rate, cumulative risk, percentage change (PC), annual percent change (APC) were calculated. Results: During 1972-2016, a total of 15 863 (male: 10 114, female: 5 749) deaths occurred attributed to stomach cancer, accounting for 16.04% of all cancers, with CR of 31.37/100 000 (CASR: 12.97/100 000, WASR: 21.39/100 000). The truncated rate of 35-64, cumulative rate of 0-74, and cumulative risk were 28.86/100 000, 2.54%, and 2.51%, respectively. For male, the CR, CASR, WASR were 40.53/100 000, 17.98/100 000, 30.13/100 000, respectively, and for female, the CR, CASR, WASR were 22.45/100 000, 8.52/100 000, 13.92/100 000, respectively. Age-specific mortality analysis showed that the mortality of each age group under 25-year-old group was less than 1/100 000. The CR increased with age. The 50-year-old group reached and exceeded the average mortality of the population, and more than 80-year-old group reached the peak of death. During 1972-2016 in Qidong, The PCs in CR, CASR, and WASR of stomach cancer were 55.43%, -52.02%, -43.60%. The APC were 0.54%, -2.30%, -2.08%, respectively. Period mortality analysis showed that except for the 75-year-old group, the mortality of stomach cancer decreased significantly. Conclusions: The crude mortality of stomach cancer increases slightly in Qidong, while the CASR and WASR decrease significantly. However, stomach cancer is still one of the malignant tumors that most affect health and seriously threat lives.

Antibiotics have been widely detected in bay ecosystems, yet little is known regarding their distribution, composition, sources, ecological and human health risks at the regional scale. We developed a systematic framework to mine data from existing publications and compiled an antibiotic concentration-based dataset containing 439 samples from 30 bays, and compared antibiotics across bays and matrices (water, sediment, and biota). Antibiotic concentrations varied considerably between bays, with hotspots occurring in East Asia. The main categories of antibiotics in waters included sulfonamide and macrolide, while tetracycline, quinolone, and macrolide antibiotics were prevalent in sediments. The main sources of antibiotics in bays included sewage treatment plant effluent, domestic sewage, agriculture runoff, and discharges from mariculture activities. Antibiotics with high ecological risks mainly included sulfamethoxazole, erythromycin, clarithromycin, and oxytetracycline. Erythromycin posed a considerable risk to human health, and the human health risks presented by other antibiotics were negligible. Regional variations of concentrations correspond to the uneven geographic consumption of antibiotics and their removal rate during wastewater treatment. Differences in antibiotics' composition between matrices are associated mainly with the physicochemical properties of antibiotics (e.g., molecular structure, solubility, and stability) and the content of total organic carbon, metal ions, chlorophyll a, and clay minerals in the sediments. To reduce the ecological and human health implications, priority should be given to the removal of erythromycin, sulfamethoxazole, oxytetracycline, and clarithromycin, with a special focus on their treatment in the Asian bay areas., (Copyright © 2021 The Authors.

Objective: To describe the trend of upper gastrointestinal cancer mortality in Qidong between 1972 and 2016, and to provide guidelines for prevention and control measures and strategies. Methods: The upper gastrointestinal data was collected in Qidong cancer registration from 1972 to 2016. Crude mortality rate (CR), China age-standardized rate (CASR), world age-standardized rate (WASR), truncated rate (35-64 years old), cumulative rate (0-74 years old) and cumulative risk were calculated. Annual percent change (APC) was calculated by Joinpoint software. Age-period-cohort model was used to analyze the influence of age, period and birth cohort on the changes in the mortality trend of upper gastrointestinal cancer patients. Results: From 1972 to 2016, there were 20 658 deaths of upper gastrointestinal cancer in Qidong, accounting for 20.89% of all cancer deaths. The CR, CASR, WASR, truncated rate (35-64 years old), cumulative rate (0-74 years old) and cumulative risk were 40.85/100 000, 27.96/100 000, 27.69/100 000, 36.01/100 000, 3.30% and 3.25%, respectively. There were 13 429 male deaths, the CR, CASR, and the WASR were 53.81/100 000, 37.62/100 000, and 39.93/100 000; the female deaths were 7 229, and the CR, CASR, and WASR were 28.23/100 000, 18.87/100 000, 17.25/100 000, respectively. The APCs of the 45-year-old, 55-year-old and 65-year-old age groups were -2.94% (95% CI: -3.32%, -2.56%), -2.94% (95% CI: -3.22%, -2.66%) and -2.04% (95% CI: -2.39%, -1.69%), with significant difference ( P <0.05), while without significance of 75-year-old group ( P >0.05). From 1972 to 2016, the APCs of CR, CASR, and WASR in the gastrointestinal cancer were 0.65% (95% CI: 0.43%, 0.87%), -2.01% (95% CI: -2.24%, -1.77%) and -2.05% (95% CI: -2.28%, -1.81%). The age-period-cohort model showed that the mortality of upper gastrointestinal cancer was increased with age ( P <0.05). Conclusions: The crude mortality of upper gastrointestinal cancer increases slightly in Qidong, while the CASR and WASR decrease significantly. However, with aged tendency of population, the early diagnosis and treatment of upper gastrointestinal cancer is still needed to be paid attention.

Clarifying the current situation of regional water pollutants and the relationship between pollutants and pollution sources is considered essential for managing the water environment. Water quality identification index (WQI), cluster analysis (CA), positive matrix factorization (PMF), and stable isotope analysis in R (SIAR) were employed to interpret a large and complex water quality data set of the Qinhuai River catchment generated during 2015 to 2019 to monitor of 11 parameters at 29 different sampling sites. WQI analysis indicated that water quality in Qinhuai River catchment is considered to have "moderate pollution," and an improving trend of water quality was observed at the interannual scale. TN was the most deteriorated of all pollution parameters. CA and PMF results on the spatial scale revealed that sampling sites located at downtown of Nanjing and Lishui District or Jangling University town were highly polluted due to the sewage from domestic sewage and business service sewage (28.88%) as well as industrial wastewater (27.43%), while sampling sites located at Hushu Street Administrative District, Ergan River, and Sangan River were slightly polluted by rural domestic wastewater and garbage (28.79%), and agricultural non-point source pollution (24.3%). The middle-lower reaches (Jiangning Development Zone and Moling Street) and middle reaches (Lukou Street Administrative District) were moderately polluted by industrial wastewater (27.25%), sewage from domestic wastewater and business service wastewater (31.62%) as well as inner sources (24.76%). The SIAR results showed that NO 3 - -N was the main nitrogen form, and the NO 3 - -N mainly originated from sewage (61%) and soil (34%) in the Yuntaishan River sub-catchment. These results will aid in the development of measures required to control water pollution in river catchments.

Objective: To explore the HIV-1 drug resistance and subtypes in newly reported HIV/AIDS patients before antiretroviral therapy (ART) in Taizhou city. Methods: A cross-sectional study of HIV-1 drug resistance was conducted among newly reported HIV/AIDS patients before ART in Taizhou from January 2016 to December 2018. HIV-1 pol gene sequences were obtained by RT-PCR. The sequences were submitted to the Stanford University drug resistance database. The drug resistance mutation and the sensitivity of HIV-1 strains to antiretroviral drugs were determined according to WHO Guidelines on HIV drug resistance surveillance of 2014. Results: A total of 806 HIV-1 pol gene sequences were obtained successfully. The overall HIV-1 drug resistance rate was 2.9% (23/806), 1.9% for non-nucleoside reverse transcriptase inhibitors (NNRTIs), 0.6% for nucleoside reverse transcriptase inhibitors (NRTIs), and 0.0% for protease inhibitors (PIs), respectively. From 2016 to 2018, the HIV-1 drug resistance rate was 1.6%, 1.8%, and 4.8%, respectively. The resistance mutations of NNRTIs and NRTIs were mainly K103 N (0.7%) and M184I/V (0.5%). HIV-1 subtypes were mostly CRF01&#95;AE (42.7%,344/806),CRF07&#95;BC (28.9%,233/806) and CRF08&#95;BC (11.2%,90/806).HIV-1 subtypes among homosexually transmitted infections were mostly CRF01&#95;AE (53.3%, 136/255) and CRF07&#95;BC (32.2%, 82/255), and HIV-1 subtypes among heterosexually transmitted infections were mainly CRF01&#95;AE (37.7%, 203/539), CRF07&#95;BC (27.5%, 148/539) and CRF08&#95;BC (16.1%, 87/539). Conclusion: HIV-1 drug resistance rate among newly reported HIV/AIDS patients before ART remained low in Taizhou during 2016 to 2018, an increasing trend seemed to be notifiable and warrants continuous surveillance of HIV-1 drug resistance.

Background: An epidemic of thunderstorm asthma in pediatric patients occurred in Yulin, a northwest city of China, on 11 September 2018. We described the epidemic and retrospectively analyzed the demographic and clinical aspects of the involved children., Methods: The caseload data of patients were collected from the hospital information system in Yulin Pediatric Hospital. The detailed document of hospitalized children with thunderstorm asthma was sourced from the medical records., Results: The mean number of daily visits to emergency/outpatient department and the daily admission to hospital were 2.7 and 16 times, respectively, than on the other days of September. A gender prominence of males was observed in both emergency/outpatient and inpatient department. Among the 51 hospitalized children with detailed medical records, 56% of them had never experienced or were diagnosed with asthma and 25% had confirmed diagnosis of asthma. Sixty-seven percent had a history of allergic rhinitis during August and September. Seventy-six percent of the hospitalized children presented as moderate asthma. Ninety-four percent of the pediatric patients had positive IgE against mugwort pollen and 78% were monosensitized to pollen., Conclusion: Thunderstorm asthma can affect children, especially who has allergic rhinitis or asthma without preventive management. Mugwort is also an aeroallergen in thunderstorm asthma attacks., Impact: Thunderstorm can induce asthma attacks in children with allergic rhinitis owing to mugwort and aggravate symptoms in children with confirmed diagnosis of asthma. Children with mugwort allergy are susceptible to thunderstorm asthma and a preponderance of boys was observed. Better identification of allergic children to mugwort, giving suitable protective measures during thunderstorm and standard therapy to existing allergic situation could be a benefit for children at risk of thunderstorm asthma.

Objective: To study the prevalence and correlates of plasma cytomegalovirus (CMV) viremia among newly reported antiretroviral therapy (ART)-naive HIV/AIDS patients in Taizhou during 2017-2018. Methods: CMV DNA was measured in plasma specimens of newly reported ART-naive HIV/AIDS patients by quantitative PCR. Both univariable and multivariable logistic regression analyses were carried out to evaluate CMV viremia correlations among the individuals. Results: Of 612 HIV/AIDS patients, 480 (78.4%) were male, 125 (20.4%) were over 60 years old, 177 (28.9%) were infected via homosexual transmission, and 430 (70.3%) via heterosexual transmission. The prevalence of CMV viremia among HIV/AIDS patients was 13.4% (82/612). Multivariable logistic regression analysis showed that the risk of CMV viremia in CD 4 + lymphocyte cells counts (CD 4 + ) ≤200 cells/μl group was higher than CD 4 counts >500 cells/μl ( OR =5.10, 95% CI :1.74-14.96, P =0.003); The median CMV DNA level (log 10 ) of 82 viremic patients was 1.57 ( P 25 , P 75 :1.04,2.13); Viremic patients with CD 4 counts ≤200 cells/μl had the highest CMV viral load ( P <0.01). Conclusions: Among ART-naive HIV/AIDS patients, the prevalence of CMV viremia was significantly associated with immunodeficiency status. Further research is needed to evaluate the association between CMV viremia and the course of HIV infection.

We used statistical approach by coupling redundancy analysis with linear regression analysis, which is useful to understand potential sources of antibiotics in the tide rising and ebbing of surface water in the Yongjiang Estuary, China. This study aimed to investigate the relationship between 29 antibiotics at five sites over four seasons and 13 environmental parameters during the tide rising and ebbing durations. The results found that dissolved organic carbon (DOC), salinity, temperature and chlorophyll a (Chla) were the main factors to impact antibiotics. The concentrations of macrolides were increasing with DOC, suggesting DOC may influence the adsorption capacity of antibiotics. The concentrations of tetracyclines had significant correlation with temperature and Chla during the tide rising period. This study demonstrated a method of exploring the relationship between the concentrations of antibiotics and environmental parameters, which is beneficial to future antibiotics research in estuaries., (Copyright © 2020 Elsevier Ltd.

Objective: To analyze influencing factors of instant antiretroviral therapy (ART) and explore associution between strategies of ART and immunological effects among HIV/AIDS patients in Taizhou city during 2006-2019. Methods: A retrospective cohort study was conducted on HIV/AIDS patients under ART, and a logistic regression model was used to analyze factors of instant ART. The student t -test and chi-square test were used to compare immunological effect of different ART strategies while the Kaplan-Meier method was used to generate a survival curve. Results: A total of 2 971 HIV/AIDS patients were enrolled with 1 786 cases (60.1%) having instant ART strategy. The proportion of instant ART were 77.8% (1 170/1 504) during 2016 to 2019. The treatment success rate of the instant ART group (87.4%, 1 561/1 786) were higher than the delayed ART group (84.4%, 1 000/1 185). The results of multivariate logistic regression model indicated that male (a OR =1.28, 95 %CI : 1.03-1.59), married (a OR =1.71, 95 %CI : 1.33-2.19) and baseline CD(4)(+)T lymphocyte cells (CD(4)) counts ≤200 cells/μl (a OR =1.60, 95 %CI : 1.27-2.02) were factors positively related to instant ART while 31-40 years old (a OR =0.63, 95 %CI : 0.48-0.84), infected through heterosexual transmission(a OR =0.60, 95 %CI : 0.49-0.74) and diagnosed before 2015 (a OR =0.20, 95 %CI : 0.17-0.23) were inversely related to instant ART. The increase of the CD(4)/CD(8) ratio was greater, and the cumulative ART success rate was higher each year in the instant ART group than in the delayed ART group ( P <0.05). Conclusions: The instant ART strategy has been well implemented in Taizhou city during 2006-2019, and the immunological effect was better in instant ART group. The proportion of instant ART were more than 60.0% among HIV/AIDS patients. Instant ART strategy needs to be strengthened for those who are 31-40 years old, women, unmarried, and infected through heterosexual transmission in an attempt to further increase treatment level and improve treatment effect.

Crude mortality rate (CR) for lung cancer in Qidong increased from 11.50/10 5 in 1972-1976 to 76.61/10 5 in 2012-2016, China age-standardized rate (CASR) from 13.11/10 5 in 1972-1976 to 34.27/10 5 in 2012-2016, and World age-standardized rate (WASR) from 13.40/10 5 in 1972-1976 to 34.30/10 5 in 2012-2016. The average annual percentage change (AAPCs) of CR, CASR, WASR were 4.87% (95% CI : 4.63%-5.12%), 2.17% (95% CI : 1.96%-2.38%), 2.12% (95% CI : 1.92%-2.33%) (all P values < 0.001), respectively. AAPCs for 45-54, 55-64, 65-74 and over 75 age groups were 0.74% (95% CI : 0.36%-1.11%), 1.23% (95% CI : 0.92%-1.53%), 2.55% (95% CI : 2.20%-2.90%), 4.26% (95% CI : 3.56%-4.96%) (all P values < 0.001), respectively.

Objective: To analyze the predictive ability of HIV infection risk assessment tool for men who have sex with men (MSM). Sentinel surveillance data of MSM in Taizhou prefecture of Zhejiang province was used. Methods: MSM involved in AIDS sentinel surveillance program in Taizhou from 2013 to 2017 were included in the study and items listed in the HIV infection risk assessment tool for MSM was revised. Related data on questions and options involved in sentinel surveillance was collected and individual risk scores were calculated. We determined the predictive ability of this tool by comprehensive analyzing the HIV infection status and individual risk scores. Results: A total of 1 944 MSM were included in the study, with an average age of (35.04±13.28)years old. Most of them were recruited from the venues (55.7%) and 48.2% were never married. Among these MSM, HIV infection rate was 12.6%(245/1 944) with the median of risk score as 23.99, versus 20.36 from the HIV negative ones. Significant differences appeared on the risk scores between the target populations that with different HIV status (Mann-Whitney test, P =0.007). According to the principle of decision tree, MSM were divided into two groups according to risk scores: ≤18.66 and >18.66. It appeared that the risk scores were in parallel with the rates of HIV infection ( χ (2)=13.102, P <0.001). Results from the multivariate analysis showed that MSM with higher risk score were more likely to be infected with HIV (>18.66 vs . ≤18.66: a OR =1.72, 95% CI : 1.27-2.32, P <0.001). Area under the ROC curve (AUC) for HIV infection was 0.553 (95% CI : 0.516-0.590, P =0.007). At the point of risk score 19.01, Youden's index appeared the maximum, with sensitivity as 0.69 and specificity as 0.43, of this tool. Conclusions: The HIV infection risk assessment tool for MSM developed based on Delphi method can predict the risk of HIV infection in MSM to some extent. MSM with higher risk score seemed likely to be infected with HIV. Items of this tool need to be adjusted for the verification of the tool through cohort studies in the near future.

The clinical presentation in Chinese patients with sporadic Creutzfeldt-Jakob disease (sCJD) may be unique due to the big difference in the codon 129 polymorphism of the prion protein gene (PRNP). This study retrospectively reviewed 26 cases of sCJD diagnosed in a single center in recent years. All 26 sCJD patients received brain magnetic resonance imaging scan, cerebrospinal fluid 14-3-3 protein detection, electroencephalogram, and PRNP gene screening. The codon 129 polymorphism were all homozygous MM in 26 sCJD patients. The main onset symptoms of sCJD patients were rapidly progressive dementia, visual impairment, and cerebellar ataxia. At the time of diagnosis, the incidence of myoclonus and akinetic mutism were relatively low (<50%). For auxiliary examinations, the positive rate of the typical magnetic resonance imaging (MRI) abnormalities, cerebrospinal fluid 14-3-3 protein, and electroencephalogram-periodic sharp wave complex was 96%, 64%, and 50%, respectively. As MM genotype is dominant and brain MRI is sensitive, brain MRI seems to play a major role in diagnosis of sCJD in Chinese.

It also discusses the development of the basic researches on male reproductive health in China and the facilitating role of NSFC in this field.

Objective: To understand the prevalence of alcohol use and related factors in HIV positive and HIV negative males. Methods: Baseline data were from the prospective cohort study of comparative HIV and aging research in Taizhou of Zhejiang province from January to December, 2017. The information about alcohol use in the last month was collected through a face-to-face questionnaire interview. Participants were categorized into non-current drinkers, light/moderate drinkers and heavy drinkers according to the US National Institute on Alcoholism and Alcohol Abuse (NIAAA) standard. Results: A total of 1 367 HIV positive males and 2 418 HIV negative males were included. Current alcohol use rate (35.2%, 481/1 367) and heavy alcohol use rate (5.0%, 24/481) were significantly lower in HIV positive males than in HIV negative males (48.0%, 1 161/2 418; 23.5%, 273/1 161), but the proportion of drinking wine and yellow rice wine were significantly higher (21.8%, 105/481; 9.1%, 44/481) in HIV positive males than in HIV negative males (13.5%, 157/1 161; 5.8%, 67/1 161). The multivariate multinomial logistic regression analysis results showed that larger waist circumference, current smoking and regular physical exercise were associated with heavy alcohol use behavior in HIV positive males, and age ≥30 years, current smoking, regular physical exercise, higher score of depressive symptoms, heterosexual transmission route and baseline CD(4)(+)T cells counts of 200-499 cells/μl were significantly associated with mild/moderate alcohol use behavior in HIV positive males. Conclusions: The alcohol use rate was significantly lower in HIV positive males than in HIV negative males in Taizhou. It is important to strengthen intervention on alcohol drinking behavior and chronic disease risk factors, such as larger waist circumference, smoking and so on.

Objective: To investigate the distribution of mitochondrial haplogroups and their correlation with neurocognitive disorder (NCD) in HIV positive individuals. Methods: Baseline data were from the prospective cohort study of comparative HIV and aging research in Taizhou of Zhejiang province from January to December, 2017. A cross-sectional survey was performed in 448 HIV positive individuals. Sanger method was used for the sequencing and genotyping of whole mitochondrial genome of HIV positive individuals. NCD prevalence in the HIV positive individuals was assessed by Mini-mental State Examination (MMSE) in questionnaire interviews. Multivariable logistic regression analysis was performed to assess the associations between mtDNA haplogroups and NCD. Results: In this sample, mitochondrial haplogroups D (19.6%, 88/448), B (19.4%, 87/448) and F(17.0%, 76/448) were the most predominant haplogroups. The overall prevalence rate of NCD was 20.3% (91/448), and was high in haplogroups A (23.1%, 9/39), D (21.6%, 19/88), F (26.3%, 20/76) and M7 groups (26.1%, 12/46), respectively. In multivariable logistic regression analysis after adjusting confounding factors, such as age and gender, compared with haplogroup A, there were no differences in the prevalence rate of NCD among HIV positive individuals with haplogroup B, D, F, M7, M8, N9, and others. Conclusion: The study explored primarily correlation between mitochondrial haplogroups and NCD among HIV positive individuals and suggested that there is no significant association between mitochondrial haplogroups and NCD, but further longitudinal investigation with large sample size of HIV positive population is needed to confirm this finding.

Caohai Plateau Wetland is a National Nature Reserve. The characteristics of stable mercury isotopic compositions in the food web were studied by comprehensively analyzing the concentrations of Hg species (MeHg, THg), δ 13 C, and δ 15 N, and the isotopic compositions of Hg in different aquatic organisms. The main results are as follows:all samples of the food web show mass-dependent fractionation (MDF) and mass-independent fractionation (MIF) and a negative δ 202 Hg(-0.93‰±1.32‰, n =14)and positive △ 199 Hg(0.79‰±0.76‰, n =14). The δ 199 Hg values are significantly positively correlated with δ 15 N ( r =0.65, P <0.05) and the δ 202 Hg values also exhibit a positive correlation with δ 15 N, except for Myriophyllum spicatum ( δ 15 N=-1.88‰), indicating that the bioaccumulation of mercury leads to an enrichment with heavier isotopes. The △ 199 Hg values increase with δ 15 N( r =0.67, P <0.05). Nevertheless, the △ 199 Hg values correlate with% MeHg ( r =0.58, P <0.05), indicating that the increase of the MIF level in the samples with the food web might be related to% MeHg.

The prevalence of low vision has increased in China especially among youth population, which is an important public health issue. The trend on the prevalence of subnormal visual acuity and updated information is essential to quantify health effects and to prompt decision makers to prioritize action and assess the effectiveness of measures. Therefore, the study aimed to analyze the prevalence and geographical distribution of visual acuity level among young men in China based on 3 national cross-sectional surveys from 1974 to 2012.The data on visual acuity of young men were collected from 3 national surveys among military recruit youth conducted in 1974, 2001, and 2012 by using a stratified cluster sampling method in China. The prevalence of visual acuity among military recruit youth during this period was analyzed by region, year, age, and economic level.A total of 139,929, 72,894, and 58,106 young men were included, covering all 31 provinces of mainland of China, from the 3 national surveys respectively. The prevalence of subnormal visual acuity had geographic diversity and increased significantly from 1974 to 2012 (P < .05). The visual acuity level was negatively correlated with the age (17-23 years) in 2012 (P < .05). Furthermore, the prevalence of subnormal visual acuity was positively correlated with the gross domestic product in 31 provinces of China (P ≤ .001).The prevalence of subnormal visual acuity increased with economic development among young men from 1974 to 2012, with distinct variation among geographic areas in China. Furthermore, subnormal visual acuity was increasingly prevalent with age and warrant public health attention.

Objective: To analyze the association between maternal bisphenol A exposure during early pregnancy and sleep problems among preschool children. Methods: Research subjects were from one of the sub-cohorts(Ma'anshan Cohort) of the China-Anhui Birth Cohort Study (C-ABCS) in Ma'anshan city. The basic situation of pregnant women and sleep information of preschool children were investigated. We selected preschool children whose mother's maternal serum bisphenol A concentrations of the first trimester had been already detected between December 2012 to Januray 2014. 1 259 pairs of mothers and children were included. The concentrations of bisphenol A exposure during early pregnancy were divided into low, medium and high exposure groups according to 25(th) percentile ( P (25)) and 75(th) percentile ( P (75)) levels. Multivariate multinomial logistic regression model was used to analyze the association between maternal bisphenol A exposure during early pregnancy and sleep-related problems in preschool children. Results: The P (50) ( P (25)- P (75)) of serum bisphenol A exposure level during early pregnancy was 0.231 (0.106-0.512) ng/ml. The sleep-related problems scores of 1 259 preschool children were (16.43±3.82) points. The occasional sleep-related problems were detected about 47.8% (602 cases) and frequent sleep-related problems were detected about 18.3% (230 cases). After the adjustment of the confounding factors such as children's gender, age, BMI, sleep position (lying down, sleeping on one's back), the length of time to sleep and the length of sleep at night, in comparison with bisphenol A low exposure group, the OR (95 %CI ) value of preschool children with occasional sleep-related problems in maternal bisphenol A high exposure group during early pregnancy was 1.44 (1.01-2.06). After the gender stratification, the results showed that in comparison with bisphenol A low exposure group, the OR (95 %CI ) value of preschool girls with occasional sleep-related problems in maternal bisphenol A medium and high exposure group during early pregnancy were 1.61 (1.05-2.46) and 2.40 (1.42-4.04), respectively. The OR (95 %CI ) value of preschool girls with frequent sleep-related problems in maternal bisphenol A high exposure group during early pregnancy was 2.64 (1.34-5.17). However, in boys, there was no statistically significant association between maternal bisphenol A exposure during early pregnancy and sleep-related problems ( P> 0.05). Conclusion: Maternal bisphenol A exposure during early pregnancy might be related to sleep-related problems in preschool children.

Objective: The purpose of this study was to investigate whether isolated maternal hypothyroxinaemia (IMH) is associated with risks of small/large-for-gestational-age (SGA/LGA) infants., Design: Population-based prospective cohort study., Setting: Ma'anshan Maternal and Child Health (MCH) clinics, China., Population: Pregnant women with singleton births (n = 3178)., Methods: Descriptive statistics were calculated for the demographic characteristics of the mothers and their newborns. Linear regression was applied to estimate the association between thyroid hormone levels and birthweight. Logistic regression was performed to calculate the association between IMH and SGA/LGA., Main Outcome Measures: Outcomes included SGA/LGA., Results: The prevalence of IMH, defined as a free thyroxine value (FT4) lower than the 2.5th percentile with normal thyroid stimulating hormone, was 2.5% (78/3080) and 2.5% (74/2999) in the first and second trimesters, respectively. Additionally, 306 (9.6%) and 524 (16.5%) infants were defined as SGA and LGA, respectively. No evidence supported the notion that IMH is associated with an increased risk for SGA in either the first [odds ratio (OR): 1.762, 95% confidence interval (CI): 0.759-4.089] or the second (OR: 0.763, 95% CI: 0.231-2.516) trimester. However, an increased risk of LGA was observed among IMH women in the second trimester (OR: 2.088, 95% CI: 1.193-3.654). Maternal TPO-Ab positivity in the second trimester increased the risk of SGA (OR: 2.094, 95% CI: 1.333-3.290)., Conclusion: This study provides evidence that IMH is associated with LGA., Funding: This work was supported by the National Natural Science Foundation of China (No. 81330068)., Tweetable Abstract: Isolated maternal hypothyroxinaemia may increase the risk of large-for-gestational-age infants., (© 2017 Royal College of Obstetricians and Gynaecologists.)

Antibiotics are used to fight diseases in humans and farm animals. Their residues, however, can enter aquatic environments and affect the resistance of non-target microbial strains, and the prevalence of antibiotic resistance genes (ARGs) potentially poses negative impacts on human health. In order to better understand how the studies of antibiotics have been conducted, we analyzed the publications on antibiotics in aquatic systems for the period of 1945-2017. We applied a bibliometric analysis method by coupling cluster analysis and network analysis. Results indicated that early research on antibiotics in water was mostly performed in America and Europe, while, in recent years, publications for the same subject were dominated by China and the USA. The majority of the articles were published in journal Chemosphere and the most representative subject categories of the seven sections were "Environmental science and ecology," "Chemistry," "Engineering," "Biochemistry and molecular biology," "Water resources," "Agriculture," and "Pharmacology and pharmacy." The most studied class of antibiotics was tetracyclines in wastewater. Antibiotic resistance, ARGs, Escherichia coli, and some mechanistic studies such as adsorption, toxicity, degradation, and kinetics were common topics in this field. ARGs present a major public health concern and much attention should be directed at the problems with antibiotics in the future studies of water.

Objective: To investigate the association between maternal pre-pregnant body mass index and gestational weight gain, as well as their interaction on neonatal birthweight. Methods: We built a cohort in Anqing Municipal Hospital from January 2014 to March 2015, enrolling pregnant women who decided to give birth in this hospital. All women were asked to fill a questionnaire for basic information collection. Medical information of both pregnant women and their newborns were obtained through electronic medical record. Chi-square analysis, multinomial logistic regression, multiplicative and additive interaction methods were used to analyze the association between pre-pregnant body mass index and gestational weight gain as well as their interactions on birth weight of the neonates. Results: A total of 2 881 pregnant women were included in this study. Of the 2 881 newborns, 359 (12.46 % ) were small for gestational age (SGA) and 273 (9.48 % ) were large for gestational age (LGA). After adjusting the possible confounding factors, results from the multinomial logistic regression showed that pre-pregnancy underweight women were more possible to deliver SGA (a RR =1.33, 95 %CI : 1.02-1.73). If the gestational weight gain was below the recommended criteria, the risk of SGA (a RR =1.64, 95 %CI : 1.23-2.19) might increase. Pre-pregnancy overweight/obese could increase the risk of being LGA (a RR =1.86, 95 %CI : 1.33-2.60). Maternal gestational weight gain above the recommendation level was associated with higher rates of LGA (a RR =2.03, 95 %CI : 1.49-2.78). Results from the interaction analysis showed that there appeared no significant interaction between pre-pregnancy BMI and gestational weight on birthweight. Conclusion: Pre-pregnancy body mass index and gestational weight gain were independently associated with neonatal birthweight while pre-pregnancy BMI and gestational weight gain did not present interaction on birthweight.
