Background: Association between breast cancer (BC) and thyroid nodules (TNs) is still unclear. This research was to estimate the prevalence and risk factors of TN in Chinese BC women at initial diagnosis., Methods: 1731 Chinese early-stage BC women at initial diagnosis underwent thyroid ultrasound and 1:1 age-matched Chinese healthy women underwent health examination in corresponding period were enrolled for analysis., Results: Prevalence of TN and TI-RADS ≥ 4 TN in BC patients (56.27% and 9.76%) were higher than healthy people (46.04% and 5.49%), respectively, P < 0.001. Among BC patients, prevalence of TN and TI-RADS ≥ 4 TN in hormone receptor (HR)-positive patients (59.57% and 11.81%) were higher than HR-negative patients (48.77% and 5.10%), respectively, P < 0.001, while without difference between HR-negative patients and healthy people. After adjusting for age and BMI, HR-positive patients had higher risk of TN (OR = 1.546, 95%CI 1.251-1.910, P < 0.001) and TI-RADS ≥ 4 TN (OR = 3.024, 95%CI 1.943-4.708, P < 0.001) than HR-negative patients. Furthermore, the risk of TI-RADS ≥ 4 TN was higher in patients with estrogen receptor (ER) positive (OR = 2.933, 95%CI 1.902-4.524), progesterone receptor (PR) positive (OR = 1.973, 95%CI 1.378-2.826), Ki-67 < 20% (OR = 1.797, 95%CI 1.280-2.522), and tumor size < 2 cm (OR = 1.804, 95%CI 1.276-2.552), respectively, P < 0.001., Conclusions: Prevalence of TN, especially TI-RADS ≥ 4 TN, in Chinese early-stage BC women was higher than healthy people. HR-positive patients had higher prevalence and risk of TN, while without difference between HR-negative patients and healthy people. The increased risk of TN was correlated with ER-positive, PR-positive, lower Ki-67 expression, and smaller tumor size., (© 2024.

Objective: To explore the characteristics of natural foci of hemorrhagic fever with renal syndrome (HFRS) in Gansu Province. Methods: The information of HFRS case data and rodent density monitoring data from 2012 to 2022 in Gansu Province were collected and epidemiological methods were used to analyze and investigate the characteristics of the epidemic focus. Results: A total of 869 cases of HFRS were reported, and four patients died from 2012 to 2022. The annual incidence rate is between 0.05 per 100 000 and 1.21 per 100 000. The cases were mainly distributed in the eastern, southeast, southern, and south of the central region of Gansu Province. Most cases were distributed between age 20-60, and the sex ratio was 1.85∶1 (564∶305). Most cases were farmers (61.80%, 537/869), herdsmen (19.79%,172/869) and students (6.33%, 55/869). In a wild rat-type epidemic focus,the incidence peak was from November to January of the following year. The natural rodent hosts of HFRS were Rattus norvegicus , Apodemus agrarius, and Mus musculus . The hantaan virus carriage rates were 2.79% (21/754), 0.42% (5/1 179) and 0.31% (2/643),respectively. Three epidemic foci were defined: two derived from the Pingliang and Gannan prefecture new outbreaks epidemic foci, respectively, while the other was the residue of the Dingxi epidemic focus. Conclusions: The southern, south of the central region and eastern part of Gansu Province are current key HFRS epidemic foci dominated by Rattus norvegicus , Apodemus agrarius, and Mus musculus , respectively. The virus genotype is hantaan virus. Case reporting areas should strengthen epidemic monitoring; the key epidemic areas should strengthen and implement various prevention and control measures to reduce the harm caused by HFRS.

Improving soil fertility is one of the key approaches for ecological restoration of the wind-sand area in northwest Liaoning Province. Taking wind-sand area in northwest Liaoning Province as test object, we conducted a fertilization experiment with treatments of inorganic fertilizer (nitrogen, phosphorus and potassium fertilizers), organic fertilizer, combined application of organic and inorganic fertilizers, and organic fertilizer combined with a biologically organic matrix (γ-polyglutamic acid), and no fertilizer as control. We measured soil organic matter content and extractable cations concentrations, vegetation coverage, and biomass under different fertilization treatments and determine the suitable fertilization mode. The results showed that compared to the control, inorganic fertilizer rapidly increased vegetation coverage and biomass, but high levels of inorganic fertilizer (150 kg N·hm -2 ) led to soil acidification and Ca 2+ leaching. Organic fertilizer increased soil organic matter content, exchangeable K + , Ca 2+ , and Mg 2+ contents, as well as coverage and biomass vegetation, especially combined with γ-polyglutamic acid. Overall, the combination of low levels of inorganic fertilizer (50 kg N·hm -2 ) and moderate levels of organic fertilizer (30000 kg·hm -2 ) was the best fertilization practice for the rapid and stable restoration of grassland in wind-sand area. Moreover, the extra addition of γ-polyglutamic acid (60 kg·hm -2 )could effectively improve soil fertility.

The construction of ecological security pattern (ESP) is of great scientific significance for solving the problem of habitat fragmentation in urban environment. However, previous studies mainly focused on the ESP in land area, leaving the sea area to be ignored. This study took the Guangdong-Hong Kong-Macao Greater Bay Area (GBA) and its offshore area as an example and integrated the land-sea coordination into the construction of ESP based on the minimum resistance model, gravity model, and graph theory centrality. The results showed that there are 171 and 56 ecological sources for land area and offshore area, accounting for 31.46% and 21.51% of total area, respectively. Twenty-four important ecological corridors with a total length of 2738.05 km were identified in GBA, and the width is proposed to be less than 100 m. Moreover, the α, β, and γ index of the ecological network in the study area is 0.19, 1.33, and 0.5, respectively, indicating that the ecological network structure is complex and the connectivity between ecological nodes is good. The ecological restoration area includes 286.6 km 2 of ecological pinch points and 140.44 km 2 of ecological barrier. The overall ESP of the study area is "one ring, two belts, and four zones." The main body of the area with a superior ecological environment is distributed in a ring-like pattern near the outer edge of the study area, and two belts (important ecological corridor and ecological corridor) are distributed in a network. According to the ecological characteristics, the study area was divided into four zones: ecological preservation areas, ecological restoration areas, limited construction areas, and optimized construction areas. The ESP established herein institute provides a reference for the revision of ecological space control and optimization measures in the GBA. It also provides effective and systematic means to solve ecological problems in the current territorial spatial planning and territorial ecological restoration of coastal urban agglomeration., (© 2023.

Introduction: Positive correlation between examination time and neoplasm detection using esophagogastroduodenoscopy (EGD) has been described by observational studies, but the effect of setting minimal examination time still requires investigation., Methods: This prospective, 2-stage, interventional study was conducted in 7 tertiary hospitals in China, enrolling consecutive patients undergoing intravenously sedated diagnostic EGDs. In stage I, the baseline examination time was collected without informing the endoscopists. In stage II, the minimal examination time was set for the same endoscopist according to the median examination time of normal EGDs in stage I. The primary outcome was the focal lesion detection rate (FDR), defined as the proportion of subjects with at least one focal lesion among all subjects., Results: A total of 847 and 1,079 EGDs performed by 21 endoscopists were included in stages I and II, respectively. In stage II, the minimal examination time was set as 6 minutes, and the median time for normal EGD increased from 5.8 to 6.3 minutes ( P < 0.001). Between the 2 stages, the FDR was significantly improved (33.6% vs 39.3%, P = 0.011), and the effect of the intervention was significant (odds ratio, 1.25; 95% confidence interval, 1.03-1.52; P = 0.022) even after adjusting for subjects' age, smoking status, endoscopists' baseline examination time, and working experience. The detection rate of high-risk lesions (neoplastic lesions and advanced atrophic gastritis) was also significantly higher in stage II (3.3% vs 5.4%, P = 0.029). In the endoscopist-level analysis, all practitioners reached a median examination time of 6 minutes, and the coefficients of variation of FDR (36.9%-26.2%) and examination time (19.6%-6.9%) decreased in stage II., Discussion: Setting a 6-minute minimal examination time significantly improved the detection of focal lesions during EGDs and has the potential to be implemented for quality improvement., (Copyright © 2023 The Author(s).

The white-backed planthopper, WBPH, Sogatella furcifera (Horváth) is a plant pest that migrates long-distances. The migration pathway of WBPH in eastern China coincides with the north-south round trip of the East Asian monsoon. However, in Yunnan China, which is affected by two monsoon systems, the migration pathway is unclear. Light-trap data and analysis of female ovarian development showed that the peak period of immigration of WBPH into western Yunnan was earlier than in eastern Yunnan. Using meteorological reanalysis data and flight parameters of WBPH, trajectory modeling showed that there are two immigration pathways to Yunnan. One is from Myanmar to western Yunnan, and the other is from Vietnam and Laos to eastern Yunnan. The reason for the differences in source areas and immigration pathways between eastern and western Yunnan is that the west wind prevails in western Yunnan and is controlled by South Asian monsoon, while southwesterly winds prevail in eastern Yunnan due to the combined influence of South Asian monsoon and East Asian monsoon. The results indicate that WBPH invades Yunnan via two pathways under a two-monsoon system. These data will allow earlier prediction and population management of WBPH., (© The Author(s) 2022.

Objective: To evaluate the efficacy and safety of Pai-Neng-Da Capsule (, panaxadiol saponins component, PNDC) in combination with the cyclosporine and androgen for patients with chronic aplastic anemia (CAA)., Methods: A total of 79 CAA patients was randomly divided into 2 groups by a random number table, including PCA group [43 cases, orally PNDC 320 mg/d plus cyclosporine 5 mg/(kg·d) plus andriol 80 mg/d] and CA group [36 cases, orally cyclosporine 5 mg/(kg·d) plus andriol 160 mg/d]. All patients were treated and followed-up for 6 treatment courses over 24 weeks. The complete blood counts, score of Chinese medical (CM) symptoms were assessed and urine routine, electrocardiogram, hepatic and renal function were observed for safety evaluation. Female masculinization rating scale was established according to the actual clinical manifestations to evaluate the accurate degree of masculinization in female CAA patients treated by andriol., Results: The effective rates were 88.1% (37/42) in the PCA group and 77.8% (28/36) in the CA group based on the standard for the therapeutic efficacy evaluation of hematopathy. There was no significant difference in the white blood cell (WBC) counts, platelet counts and hemoglobin concentration of peripheral blood between two groups after 6 months treatment. The masculinization score of female patient in the PCA group was significantly lower than the CA group (P<0.05). The mild abdominal distention was observed in 1 cases in the PCA group. In CA group, the abnormalities in the hepatic function developed in 2 cases and the renal disfunction was found in 1 case., Conclusion: The PNDC possesses certain curative effects in the treatment of CAA without obvious side-effects and can partially replace andriol thereby to reduce the degree of masculinization [Registried at Chinese Clinical Trial Registry (ChicTR1900028153)]., (© 2020.

In this study, Illumina MiSeq sequencing of the 16 S rRNA gene was used to describe the bacterial communities in the South China Sea (SCS) during the southwest monsoon period. We targeted different regions in the SCS and showed that bacterial community was driven by the effects of the river, upwelling, and mesoscale eddy through changing the environmental factors (salinity, temperature, and nutrients). Distinct bacterial communities were observed among different chemical conditions, especially between the estuary and the open sea. The abundance of Burkholderiales, Frankiales, Flavobacteriales, and Rhodobacterales dominated the estuary and its adjacent waters. Bacteria in cyclonic eddy were dominated by Methylophilales and Pseudomonadales, whereas Prochlorococcus, SAR11 clade, and Oceanospirillales had relatively high abundance in the anticyclonic eddy. Overall, the abundance of specific phylotypes significantly varied among samples with different chemical conditions. Chemical conditions probably act as a driver that shapes and controls the diversity of bacteria in the SCS. This study suggests that the interaction between microbial and environmental conditions needs to be further considered to fully understand the diversity and function of marine microbes., (© 2021.

We conducted a large-scale epidemiological investigation to detect the prevalence of Toxoplasma gondii in four marine bivalve shellfish species collected from six representative coastal regions of Weihai, eastern China. Between January 2018 and December 2018, 14,535 marine bivalve shellfish pooled into 2907 samples were randomly collected and examined for T. gondii DNA by a nested PCR assay targeting B1 gene. The results showed that 2.8% (82) of the 2907 pooled samples were tested positive for T. gondii DNA. Two T. gondii genotype (ToxoDB Genotype #9 and ToxoDB Genotype #1) were identified PCR-restriction fragment length polymorphism analysis. Factors that were found significantly associated with the presence of T. gondii DNA in marine bivalve shellfish included the source of samples (being wild) (odds ratio [OR], 3.34; 95% confidence interval [CI], 2.00-5.84; p < 0.01), surface runoff near the sampling site (OR, 2.64; 95% CI, 1.47-4.72; p < 0.01), and presence of cats near the sampling site (OR, 1.77; 95% CI, 1.02-3.07; p = 0.04). Moreover, the prevalence of T. gondii DNA in marine bivalve shellfish correlated with temperature (Pearson's correlation: R = 0.75, p = 0.0049) and precipitation (R = 0.87, p = 0.00021). These findings provide new insights into the presence of T. gondii DNA in marine bivalve shellfish and highlight the impact of human activity on marine pollution by such an important terrestrial pathogen pollutant., (Copyright © 2021 The Authors.

Increasing evidence exisits for the role that shellfish play in the epidemiology of Toxoplasma gondii in marine environment. However, limited information is available on the level of T. gondii infection in wild marine snails, which can play a role in the transmission of T. gondii to other marine organisms and humans. In this study, the prevalence of T. gondii DNA in wild marine snails collected from three coastal cities in China was determined. Between January 2018 and November 2019, 1,206 wild marine snails were randomly collected and examined for the presence of T. gondii DNA using a nested polymerase chain reaction (PCR) targeting T. gondii B1 gene. The amplified products were genotyped using multilocus PCR-restriction fragment length polymorphism analysis. We also examined whether species of snail, sampling region, sampling season, surface runoff near samplic site, residential water discharge near samplic site, and proximity to livestock farms are associated with the occurrence of T. gondii DNA in marine snails. Our results showed that 23 (1.91%) snails were positive for T. gondii B1 gene. The genotype of two of the 23 T. gondii amplicons was consistent with ToxoDB Genotype #9. Multiple logistic regression revealed that surface runoff near the sampling site (P = 0.039, odds ratio [OR] = 3.413, 95% confidence interval [CI]: 1.07-10.94) and residential water discharge near the sampling site (P = 0.021, OR = 3.990, 95%CI: 1.24-12.87) are more likely to be associated with the presence of T. gondii DNA in marine snails. The detection of T. gondii DNA in marine snails in China highlights the potential impact of the anthropogenic activities on marine organisms and the potential foodborne risk posed to humans with such an important terrestrial pathogen., (Copyright © 2020 Elsevier B.V.

Grazing by livestock greatly affects the soil carbon (C) cycle in grassland ecosystems. However, the effects of grazing at different intensities and durations on the dynamics of soil C in its subsoil layers are not clearly understood. Here, we compiled data from 78 sites (in total 122 published studies) to examine the effects of varying grazing intensities and durations on soil C content at different depths for grasslands in China. Our meta-analysis revealed that grazing led to an overall decrease in soil C content and productivity of above-ground vegetation (e.g., above-ground biomass and litter) but an increase in below-ground biomass. Specifically, the effects of grazing on soil C content became less negative or even positive with increasing soil depths. An increase of soil C content was consequently found under light grazing (LG), although soil C content still decreased under moderate and heavy grazing. The increase in soil C content under LG could be largely attributed to the increase of soil C content in subsoil layers (>20 cm), despite that soil C content in surface soil layer (0-20 cm) decreased. Moreover, the magnitude of increase in soil C content under LG in subsoil layers increased with grazing duration. A possible reason of the increase in soil C content in the subsoil layers was due to the increases in below-ground biomass. Our study highlights that LG may modify the allocation of C input and promote its accumulation in subsoil layers, thus offsetting the negative impact of grazing on surface soil C content, a finding that has significant implications for C sequestration in grasslands., (© 2020 John Wiley & Sons Ltd.)

Background: The catheter-tissue contact force (CF) is one of the significant determinants of lesion size and thus has a considerable impact on the effectiveness of ablation procedures. This study aimed to evaluate the impact of CF on the lesion size during right ventricular outflow tract (RVOT) ablation in a swine model., Methods: Twelve Guangxi Bama miniature male pigs weighing 40 to 50 kg were studied. After general anesthesia, a ThermoCool SmartTouch contact-sensing ablation catheter was introduced to the RVOT via the femoral vein under the guidance of the CARTO 3 system. The local ventricular voltage amplitude and impedance were measured using different CF levels. We randomly divided the animals into the following four groups according to the different CF levels: group A (3-9 g); group B (10-19 g); group C (20-29 g); and group D (30-39 g). Radiofrequency ablations were performed at three points in the free wall and septum of the RVOT in power control mode at 30 W for 30 s while maintaining the saline irrigation rate at 17 mL/min. At the end of the procedures, the maximum depth, surface diameter, and lesion volume were measured and recorded. A linear regression analysis was performed to determine the relationship between continuous variables., Results: A total of 72 ablation lesions were created in the RVOT of the 12 Bama pigs. The maximum depth, surface diameter, and volume of the lesions measured were well correlated with the CF (free wall: β = 0.105, β = 0.162, β = 3.355, respectively, P < 0.001; septum: β = 0.093, β = 0.150, β = 3.712, respectively, P < 0.001). The regional ventricular bipolar voltage amplitude, unipolar voltage amplitude, and impedance were weakly positively associated with the CF (β = 0.065, β = 0.125, and β = 1.054, respectively, P < 0.001). There was a significant difference in the incidence of steam pops among groups A, B, C, and D (free wall: F = 7.3, P = 0.032; septum: F = 10.5, P = 0.009); and steam pops occurred only when the CF exceeded 20 g. Trans-mural lesions were observed when the CF exceeded 10 g in the free wall, while the lesions in the septum were non-trans-mural even though the CF reached 30 g., Conclusions: CF seems to be a leading predictive factor for the size of formed lesions in RVOT ablation. Maintaining the CF value between 3 and 10 g may be reasonable and effective for creating the necessary lesion size and reducing the risk of complications, such as steam pops and perforations.

Identifying the spatio-temporal variations of evapotranspiration (ET) from its components (soil evaporation and plant transpiration) can greatly improve our understanding of water-cycle and biogeochemical processes. However, partitioning evapotranspiration into evaporation (E) and transpiration (T) at regional scale with high accuracy still remains a challenge. This study has aimed to reveal the spatio-temporal variations of evapotranspiration and its components by using an improved Shuttleworth-Wallace (SWH) model to partition ET in the Yellow River Basin during 1981-2010. The environmental factors affecting the spatial and temporal variations of evapotranspiration and its components were also assessed. Results showed that the mean annual ET, T and E in the Yellow River Basin were 372.18 mm, 179.64 mm, and 192.54 mm, respectively, over the last 30 years. The spatial pattern of mean annual ET and T displayed a decreasing trend from southeast to northwest in the Yellow River Basin, and the temporal variation showed a significant increasing trend with rates of 1.72 mm yr -1 and 1.54 mm yr -1 , respectively. It meant that T accounted for the variations of ET, while E showed no significant changes in recent decades. Moreover, the normalized differential vegetation index (NDVI) and temperature were identified as the main factors controlling the variations of ET and T in the Yellow River Basin. Among them, the area with NDVI as the dominant factor for ET and T could reach 63.82% and 78.47% of the whole basin respectively. However, the variations of E were affected by complex factors, and evaporation in the western alpine region was mainly controlled by temperature. Our findings are expected to not only have implications for developing sustainable policies of water management and ecological restoration in this region, but also provide valuable insight in methodology of ET partitioning in regional or global scale., Competing Interests: Declaration of interests 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 © 2020 Elsevier Ltd.

Background: Despite the recent advances in treatments for rheumatoid arthritis (RA), there are still unmet needs in disease outcomes. This study aimed to analyze the satisfaction with drug therapies for RA according to the levels of disease severity (patient-assessed) and proportions of treatment cost to household income., Methods: This was a subgroup study of a cross-sectional study in patients with RA and their physicians. The patients were subdivided into different subgroups based on their self-assessed severity of RA and on the proportions of treatment cost to household income (<10%, 10-30%, 31-50%, and >50%). The Treatment Satisfaction Questionnaire for Medication version II was used to assess patients' treatment satisfaction., Results: When considering all medications, effectiveness, convenience, and global satisfaction scores were lower in the severe and moderate RA subgroups than those in the mild and extremely mild RA subgroups (all P < 0.001). Effectiveness, side effects, and convenience scores were higher in the <10% subgroup compared to those in the >50% subgroup (all P < 0.05). Global satisfaction score was higher in the <10% subgroup than that in the 31% to 50% subgroup (F = 13.183, P = 0.004). For biological disease-modifying anti-rheumatic drugs, effectiveness and convenience scores were lower in the severe RA subgroup than those in the extremely mild RA subgroup (both P < 0.05). Convenience score was higher in the <10% subgroup compared to that in the 31% to 50% and >50% subgroups (F = 12.646, P = 0.005). Global satisfaction score was higher in the <10% subgroup than that in the 31% to 50% subgroup (F = 8.794, P = 0.032)., Conclusion: Higher disease severity and higher financial burden were associated with lower patient satisfaction.

Objectives: The different etiology of HF has different prognostic risk factors. Prognosis assessment of ICM and NICM has important clinical value. This study is aimed to explore the predicting factors for ICM and NICM., Methods: 1082 HFrEF patients were retrospectively enrolled from Jan. 01, 2016 to Dec. 31, 2017. On Jan. 31, 2019, 873 patients were enrolled for analysis excluding incomplete, unfollowed, and unexplained data. The patients were divided into ischemic and non-ischemic group. The differences in clinical characteristics and long-term prognosis between the two groups were analyzed, and multivariate Cox analysis was used to predict the respective all-cause mortality, SCD and rehospitalization of CHF., Results: 873 patients aged 64(53,73) were divided into two groups: ICM (403, 46.16%) and NICM. At the end, 203 died (111 in ICM, 54.68%), of whom 87 had SCD (53 in ICM, 60.92%) and 269 had rehospitalization for HF(134 in ICM, 49.81%). Independent risk factors affecting all-cause mortality in ICM: DM, previous hospitalization of HF, age, eGFR, LVEF; for SCD: PVB, eGFR, Hb, revascularization; for readmission of HF: low T3 syndrome, PVB, DM, previous hospitalization of HF, eGFR. Otherwise; factors affecting all-cause mortality in NICM: NYHA III-IV, paroxysmal AF/AFL, previous hospitalization of HF, β-blocker; for SCD: low T3 syndrome, PVB, nitrates, sodium, β-blocker; for rehospitalization of HF: paroxysmal AF/AFL, previous admission of HF, LVEF., Conclusions: Both all-cause mortality and SCD in ICM is higher than that in NICM. Different etiologies of CHF have different risk factors affecting the prognosis., Competing Interests: Conflicts of interest There is no conflict of interest., (Copyright © 2020.

A new benzylated alkamide, N -(3,4-dimethoxybenzyl)-9 Z -oleamide ( 1 ), along with two known ones ( 2 and 3 ) were isolated from the roots of Lepidium meyenii collected from Lijiang, Yunnan Province of China. Their structures were elucidated by extensive spectroscopic analyses and the new compound further confirmed by a one-step synthesis. All the isolated alkamides were evaluated for their cytotoxicity against five human cancer cell lines. However, no significant activities were detected at concentrations up to 40  μ M.

Objective: To analyze the epidemiological and spatial-temporal distribution of Brucellosis, epidemic encephalitis B and hemorrhagic fever with renal syndrome (HFRS) in Gansu province during 2014-2018 so as to provide evidence for the prevention and control of those diseases. Methods: A database was established in Gansu province from 2014 to 2018, using the geographical information system. A spatial distribution map was drawn, with trend analysis and space-time clustering used to study the 3-dimention of the diseases, by using both ArcGIS 10.5 and SaTScan 9.6 softwares. Results: Results from the trend surface analysis showed that the incidence of Brucellosis decreased gradually from north to south parts while the U type curve could reflect the distribution from the east to the west areas. Incidence of epidemic encephalitis B decreased significantly from south to north areas in the province, with incidence higher in the eastern than in the mid-west region. Difference on the incidence of HFRS was not significantly visible in the eastern and western regions, while the incidence was slightly higher in the southern than the northern parts of the province. Spatial and space-time clustering did exist among the 3 diseases in Gansu from 2014 to 2018. The areas with clusters of Brucellosis appeared in the eastern parts during 2014-2015, including 19 counties. The areas with secondary clusters of Brucellosis were seen in the Hexi district, including 4 counties, during 2017-2018. The areas with high incidence of epidemic encephalitis B were clustered in the middle and southeast areas, including 32 counties, during 2017-2018. Areas with most clusters of HFRS appeared in Min county of Dingxi city in 2018, with the areas of secondary clusters in 8 counties of the eastern areas in 2018. Conclusions: The overall incidence rates of the 3 natural focus diseases were in a upward trend and showing obvious characteristics on spatial clustering. According to the distributive characteristics, effective measures should be developed accordingly.

Objective: To investigate the use of antibiotics in children with community-acquired pneumonia (CAP) in multiple regions of China, and to provide a reference for CAP standard treatment and rational antibiotic use in children., Methods: The medical data of 1 383 children with CAP who were hospitalized in the department of pediatrics in 10 grade A tertiary hospitals from 9 cities between April 14, 2014 and January 1, 2016 were reviewed, to analyze the status of antibiotic use in hospitalized children in North China, Northeast China, East China, and South China., Results: The overall rate of antibiotic use in children with CAP was 89.08%, with 88.7% in North China, 95.5% in Northeast China, 83.3% in East China, and 86.6% in South China. The main types of antibiotics used were cephalosporins, macrolides, compound preparations of β-lactam antibiotics, polyphosphoric broad-spectrum antibiotics and other β-lactam antibiotics. The selection of antibiotics was generally rational, but antibiotics were still used in some patients with viral infection alone or a combined use of ≥2 kinds of antibiotics were noted in some patients with infection caused by one kind of pathogen. Irrational antibiotic use was observed in 131 children (10.63%)., Conclusions: There are high rates of antibiotic use and irrational use of antibiotics among children with CAP. Standard management of antibiotic use in children with CAP should be strengthened.

Niemann Pick Type C1 Like 1 (NPC1L1) protein plays a key role in intestinal and hepatic cholesterol metabolism in humans. Genetic variation in NPC1L1 has been widely studied in recent years. We analyzed NPC1L1 single nucleotide polymorphisms in Chinese gallstone disease patients to investigate their association with gallstone disease. NPC1L1 mRNA expression was also measured in liver biopsies from patients with cholesterol gallstone disease and compared between genotypes. The G allele of the g1679C>G (rs2072183) polymorphism was significantly more prevalent in patients with gallstones compared with gallstone-free subjects. Moreover, patients carrying the G allele had lower hepatic NPC1L1 mRNA expression and higher biliary cholesterol (molar percentages) and cholesterol saturation index. Our study suggests that the G allele of the NPC1L1 polymorphism g1679C>G may be a positive marker of gallstone formation risk.

The Pearl River is located in the northern part of South China Sea. The environment of the Pearl River estuary (PRE) is significantly impacted by nutrients from anthropogenic activities. Along the anthropogenic pollution gradient from the PRE to South China Sea, the phylogenetic diversity and biomass of phytoplankton was examined in relation to physic-chemical variables. The richness of rbcL gene was higher in the open sea than the estuary, while the concentration of chlorophyll a (Chl a) was higher in the estuary than in the open sea. The cluster analysis of the sequences data resulted in seven phytoplankton community types and the dominant species of phytoplankton changed from Cryptophytes and Diatoms to Prymnesiophytes and Diatoms along the gradient. The community structure of phytoplankton was shaped by nutrients and salinity. The phytoplankton biomass was significantly positively affected by phosphorus, nitrite and ammonium (P < 0.01) but negatively by salinity (P < 0.05); the phytoplankton diversity was highly positively affected by salinity (P < 0.05) but negatively by silicate and nitrate (P < 0.01; P < 0.05, respectively). Anthropogenic activities played a critical role in the phytoplankton distribution and biomass of the study area. Further research is necessary to reveal the influence mechanism of environmental factors on the phytoplankton.

Daya Bay is one of the largest and most important gulfs in the southern coast of China, in the northern part of the South China Sea. The phylogenetic diversity and spatial distribution of phytoplankton from the Daya Bay surface water and the relationship with the in situ water environment were investigated by the clone library of the large subunit of ribulose-1, 5-bisphosphate carboxylase (rbcL) gene. The dominant species of phytoplankton were diatoms and eustigmatophytes, which accounted for 81.9 % of all the clones of the rbcL genes. Prymnesiophytes were widely spread and wide varieties lived in Daya Bay, whereas the quantity was limited. The community structure of phytoplankton was shaped by pH and salinity and the concentration of silicate, phosphorus and nitrite. The phytoplankton biomass was significantly positively affected by phosphorus and nitrite but negatively by salinity and pH. Therefore, the phytoplankton distribution and biomass from Daya Bay were doubly affected by anthropic activities and natural factors.

Mangrove is a special coastal forest along tropical and subtropical intertidal shores. However, how mangroves adapt to tidal flooding and the mechanisms involved in mangrove zonation are still poorly understood. In this study, a pot trial with different tide treatments was conducted to investigate the differences in root anatomy, porosity, radial oxygen loss, iron plaque formation and waterlogging tolerance among six mangroves along a continuous tidal gradient. The index of waterlogging tolerance illustrated that Sonneratia apetala possessed the highest index, followed by Aeguceras corniculatum/Kandelia, Rhizophora stylosa, Heritiera littorlis and Thespesia populnea. Waterlogging tolerances of the mangroves were found to be positively correlated with their root porosity, radial oxygen loss and iron plaque formation. Waterlogging-sensitive species such as landward semi-mangroves exhibited small root porosity and ROL, while waterlogging-tolerant species such as seaward pioneer and rhizophoraceous mangroves exhibited extensive porosity, ROL and iron plaque formation. Nevertheless, grater root porosity and iron plaque formation were detected in permanent waterlogged plants when compared to drained plants. In conclusion, The present study proposes a structural adaptive strategy to tidal flooding in mangroves, such that the mangroves with higher root porosity, ROL and iron plaque appeared to exhibit higher waterlogging tolerance and adaptability in anaerobic foreshores.

To evaluate the incidence and risk factors for human immunodeficiency virus (HIV) seroconversion of HIV-negative partners among HIV-discordant couples in Liuzhou, China, 1854 eligible HIV-serodiscordant couples were retrospectively identified through the HIV epidemiology and follow-up database from January 1, 1996 to June 30, 2013. Cox proportional-hazards model was used to examine risk factors related to HIV seroconversion of negative partners. Finally, 125 HIV seroconversion occurred over 4963.5 person-years, resulting in an overall HIV incidence of 2.52/100 person-years. HIV-positive partners with the last CD4 counts of 350 cells/ul or more were significantly protected against HIV seroconversion compared with those CD4 counts of less than 200 cells/ul (aHR = 0.46, 95% CI: 0.27-0.81, P < 0.01). Men with HIV-positive wives (aHR: 1.96, 95% CI: 1.27-3.02, P < 0.01), HIV-positive partners who did not receive ART before their HIV-negative partners' seroconversion (aHR: 2.22, 95% CI, 1.41-3.51, P < 0.01) and patients reported intermittent condom use (aHR: 7.60, 95% CI, 4.37-13.21, P < 0.01) were associated with increased risk of HIV seroconversion. HIV-negative partners remain high risk of HIV infection in Liuzhou city. Comprehensive package of HIV prevention services should contribute to reduction in HIV transmission of discordant couples., (© 2015 Wiley Periodicals, Inc.)

Pyrosequencing of the 16S ribosomal RNA gene (rDNA) amplicons was performed to investigate the unique distribution of bacterial communities in northern South China Sea (nSCS) and evaluate community structure and spatial differences of bacterial diversity. Cyanobacteria, Proteobacteria, Actinobacteria, and Bacteroidetes constitute the majority of bacteria. The taxonomic description of bacterial communities revealed that more Chroococcales, SAR11 clade, Acidimicrobiales, Rhodobacterales, and Flavobacteriales are present in the nSCS waters than other bacterial groups. Rhodobacterales were less abundant in tropical water (nSCS) than in temperate and cold waters. Furthermore, the diversity of Rhodobacterales based on the gene transfer agent (GTA) major capsid gene (g5) was investigated. Four g5 gene clone libraries were constructed from samples representing different regions and yielded diverse sequences. Fourteen g5 clusters could be identified among 197 nSCS clones. These clusters were also related to known g5 sequences derived from genome-sequenced Rhodobacterales. The composition of g5 sequences in surface water varied with the g5 sequences in the sampling sites; this result indicated that the Rhodobacterales population could be highly diverse in nSCS. Phylogenetic tree analysis result indicated distinguishable diversity patterns among tropical (nSCS), temperate, and cold waters, thereby supporting the niche adaptation of specific Rhodobacterales members in unique environments.

Metal pollution has been widely reported in mangrove wetlands; however, the mechanisms involved in metal detoxification by mangroves are still poorly understood. This study aimed to investigate the possible function of root anatomy and lignification/suberization on metal uptake and tolerance in seedlings of six species of mangroves. The results revealed that the three rhizophoraceous species (Bruguiera gymnorrhiza (L.) Poir, Kandelia obovata Sheue, Liu & Yong and Rhizophora stylosa Griff) consistently exhibited higher metal tolerances than the three pioneer species (Aegiceras corniculatum (Linn.) Blanco, Acanthus ilicifolius L. and Avicennia marina (Forsk.) Viern.). Moreover, metal-tolerant species often exhibited a thick exodermis with high lignification and suberization. The tolerance indices of the mangroves were found to be positively correlated with the amounts of lignin and suberin deposition within the exodermal cell walls. The observed metal uptake by the excised roots further illustrated that a lignified/suberized exodermis directly delayed the entry of metals into the roots, and thereby contributed to a higher tolerance to heavy metals. In summary, the present study proposes a barrier property of the lignified/suberized exodermis in dealing with the stresses of heavy metals, such that the mangroves which possessed more extensive lignification/suberization within the exodermis appeared to exhibit higher metal tolerance., (© The Author 2014.

Background: Community-acquired pneumonia in children is common in China. To understand current clinical characteristics and practice, we conducted a cross-sectional study to analyze quality of care on childhood pneumonia in eight eastern cities in China., Methods: Consecutive hospital records between January 1, 2010 and December 31, 2010 were collected from 13 traditional Chinese medicine (TCM) and western medicine (WM) hospitals in February, May, August, and November (25 cases per season, 100 cases over the year), respectively. A predesigned case report form was used to extract data from the hospital medical records., Results: A total of 1298 cases were collected and analyzed. Symptoms and signs upon admission at TCM and WM hospitals were cough (99.3% vs. 98.6%), rales (84.8% vs. 75.0%), phlegm (83.3% vs. 49.1%), and fever (74.9% vs. 84.0%) in frequency. Patients admitted to WM hospitals had symptoms and signs for a longer period prior to admission than patients admitted to TCM hospitals. Testing to identify etiologic agents was performed in 1140 cases (88.4%). Intravenous antibiotics were administered in 99.3% (595/598) of cases in TCM hospitals and in 98.6% (699/700) of cases in WM hospitals. Besides, Chinese herbal extract injection was used more frequently in TCM hospitals (491 cases, 82.1%) than in WM hospitals (212 cases, 30.3%) (p < 0.01). At discharge, 818 cases (63.0%) were clinically cured, with a significant difference between the cure rates in TCM (87.6%) and WM hospitals (42.0%) (OR = 9.8, 95% confidence interval (CI): 7.3 ~ 12.9, p < 0.01). Pathogen and previous medical history were more likely associated with the disappearance of rales (OR = 7.2, 95% CI: 4.8 ~ 10.9). Adverse effects were not reported from the medical records., Conclusions: Intravenous use of antibiotics is highly prevalent in children with community-acquired pneumonia regardless of aetiology. There was difference between TCM and WM hospitals with regard to symptom profile and the use of antibiotics. Intravenous use of herbal injection was higher in TCM hospitals than in WM hospitals. Most of the cases were diagnosed based on clinical signs and symptoms without sufficient confirmation of aetiology. Audit of current practice is urgently needed to improve care.

Human leukocyte antigen (HLA) class II molecule is an integral component of the immune response on which the majority of host genetic studies have concentrated. Many different HLA-II alleles have been demonstrated to play roles in HBV infection. PCR-SSOP methods were applied to determine the HLA-DRB1 genotypes of 769 unrelated healthy individuals from Han Chinese of Northeast China. The frequencies of HLA-DRB1*09 in hepatitis B virus (HBV)-infected subjects were higher compared to those in the control group. Frequencies of HLA-DRB1*04 and *13 in the HBV-infected group were significantly lower compared to those in the healthy control group. Frequencies of HLA-DRB1*12 in the cirrhosis and liver cancer groups were significantly higher than those in the chronic hepatitis B (CHB) patients. The frequency of LA-DRB1*03 in the CHB patient group was significantly higher compared to that in the asymptomatic hepatitis B carrier patients. The above results suggest that the host HLA-II gene is an important factor in the determination of the outcome of HBV infection.

Objective: To analyze the polymorphism of natural killer cell immunoglobulin-like receptor (KIR)gene and the characteristics of its genotypes and haplotypes in Korean ethnic group of Jilin area, and to compare with that of Han nationality., Methods: DNA samples randomly collected from 214 Han and 160 Korean populations were genotyped with PCR-SSP method, and KIR genotypes and haplotypes were assigned according to the standard model by Hsu et al., Results: All individuals contain KIR 3DL3, KIR 2DL4, KIR 3DL2 with the genotype frequency of 100%; the most common genotypes were 2DL1, 2DL3, 3DL1, 3DP1(*)003 and 2DP1; the genotypes with low frequency were 2DL2, 2DS2, 2DS3, 3DP1(*)001/002/004. Thirty-nine different KIR genotype and 16 haplotypes had been found in Korean and Han individuals. The most common KIR genotypes were AJ and AF with frequency of 18.1%, 19.4% and 31.8%, 19.6%, respectively. The most common KIR haplotype was haplotype 2 with frequency of 41.8% (n = 127) and 51.2% (n = 216) (P < 0.05), respectively., Conclusion: KIR gene distribution in Jilin Korean ethnic group showed some common features of KIR gene polymorphisms in Chinese Han population, but also showed this nation's unique characteristics of KIR gene polymorphism.

Species delimitation detected by molecular markers is complicated by introgression and incomplete lineage sorting between species. Recent modeling suggests that fixed genetic differences between species are highly related to rates of intraspecific gene flow. However, it remains unclear whether such differences are due to high levels of intraspecific gene flow overriding the spread of introgressed alleles or favoring rapid lineage sorting between species. In pines, chloroplast (cp) and mitochondrial (mt) DNAs are normally paternally and maternally inherited, respectively, and thus their relative rates of intraspecific gene flow are expected to be high and low, respectively. In this study, we used two pine species with overlapping geographical distributions in southeast China, P. massoniana and P. hwangshanensis, as a model system to examine the association between organelle gene flow and variation within and between species. We found that cpDNA variation across these two pine species is more species specific than mtDNA variation and almost delimits taxonomic boundaries. The shared mt/cp DNA genetic variation between species shows no bias in regard to parapatric versus allopatric species' distributions. Our results therefore support the hypothesis that high intraspecific gene flow has accelerated cpDNA lineage sorting between these two pine species.

Background: Cholesterol gallstone disease is a very common disease in both industrialized and developing countries. Many studies have found that cholesterol gallstones are more common in women than men. The molecular mechanisms underlying the relationship between female gallstone disease and hepatic sterol transporters are still undergoing definition and have not been evaluated in humans., Aims: The aim of this study is to probe for underlying hepatic molecular defects associated with development of gallstones in female., Methods/results: Fifty-seven nonobese, normolipidemic Chinese female gallstone patients (GS) were investigated with 12 age- and body mass index-matched female gallstone-free controls (GSF). The bile from the female GS had higher cholesterol saturation than that from the female GSF. The hepatic NPC1L1 mRNA levels were lower in female GS, correlated with SREBP2 mRNA. NPC1L1 downregulation was confirmed at protein levels. Consistently, immunohistochemistry showed decreased NPC1L1 expression in female GS., Conclusions: The decreased hepatic NPC1L1 levels in female GS might indicate a downregulated reabsorption of biliary cholesterol in the liver, which, in turn, leads to the cholesterol supersaturation of bile. Our data are consistent with the possibility that hepatic NPC1L1 may be mediated by SREBP2.

Objective: ACAT2 is a major cholesterol esterification enzyme specifically expressed in hepatocytes and may control the amount of hepatic free (unesterified) cholesterol available for secretion into bile or into HDL. This study aims to further elucidate physiologic roles of ACAT2 in human hepatic cholesterol metabolism., Methods and Results: Liver biopsies from 40 normolipidemic, non-obese gallstone patients including some gallstone-free patients (female/male, 18/22) were collected and analyzed for microsomal ACAT2 activity, protein and mRNA expression. Plasma HDL-cholesterol (HDL-C) was significantly higher in females than in males, while triglycerides were significantly lower. ACAT2 activity in females was significantly lower than observed in males, regardless of the presence of gallstone disease. Moreover, the activity of ACAT2 correlated negatively with plasma levels of HDL-C (r=-0.57, P<0.05) and with Apo AI (r=-0.49, P<0.05)., Conclusion: This is the first description of a gender-related difference in hepatic ACAT2 activity in normolipidemic non-obese Chinese patients suggesting a possible role for ACAT2 in the regulation of cholesterol metabolism in humans. The negative correlation between ACAT2 activity and HDL-C or Apo AI may reflect this regulation. Since ACAT2 activity generally has been found to be pro-atherogenic in animal models, the observed sex-related difference may contribute to female protection from complications of coronary heart disease (CHD).

Background: Supersaturation of bile with cholesterol is a primary step in the formation of cholesterol gallstones. ATP binding cassette (ABC) G5 and G8 play an important role in regulating sterol absorption and secretion. To investigate a possible association between transporter gene polymorphism and gallstone formation, we examined five common polymorphisms in the ABCG5 (Q604E) and ABCG8 (D19H, Y54C, T400K, A632V) genes in patients with gallstone disease (GS)., Methods: Study subjects included 287 patients with GS and 219 gallstone free controls (GSF). Polymorphisms were determined using PCR-RFLP analysis or the Taqman MGB assay. Plasma and biliary lipid levels were measured., Results: 2 SNPs of ABCG8 gene (Y54C and T400K) showed strong linkage disequilibrium (D'=0.824, r2=0.579). Male carriers of the less frequent K allele of ABCG8 T400K had a 2.31-fold elevated risk [95% confidence interval (CI) 1.12 approximately 4.76, P=0.023] for gallstone disease compared to male with the common genotype after the adjustment for age, body mass index. Males with the K allele had lower plasma triglyceride (P=0.044) and biliary phospholipid (P=0.035) levels than TT homozygotes. No such association was found in female or other 4 SNPs., Conclusions: These findings indicate that the T400K polymorphism in ABCG8 may be associated with the incidence of gallstone disease in males.

The natural radioactivity of soils at the Xiazhuang granite massif of Southern China has been studied. The radioactivities of 55 samples have been measured with a low-background HPGe detector. The radioactivity concentrations of (238)U and (40)K ranged from 40.2 to 442 and from 442 to 913 Bq/kg, respectively, while the radioactivity concentration of (232)Th varied only slightly. In order to evaluate the radiological hazard of the natural radioactivity, the radium equivalent activity (Ra(eq)), the absorbed dose rate (D ), the annual effective dose rate and the external hazard index (H(ex)) have been calculated and compared with the internationally approved values. The study provides background radioactivity concentrations in a granite area, specifically, the area in the vicinity of a uranium mine in Southern China. The data can be used in exploring granite-type uranium deposits.

Objective: To explore the role of both inheritable and epidemiological factors in the pathogenesis of familial gallstone disease in pedigrees., Methods: 135 pedigrees, with 695 members aged > or = 18 (18 - 83, with a mean of 50 +/- 14), 282 males and 413 females, including 370 patients, at least one patient existing in every generation, were investigated. Inquiry was carried out to collect the personal and medical history. Physical examination and ultrasonography were conducted. Blood samples were collected to detect the total cholesterol (TCh), triglyceride (TG), high-density lipoprotein cholesterol (HDL-Ch), and apolipoprotein (Apo) A1 and ApoB. The concentration of low-density lipoprotein cholesterol (LDL-Ch) was calculated by the formula: Tch-TG/5 + HDL-Ch. The inheritable characteristics and heritability were analyzed., Results: The prevalence of gallstone disease was 53.24%, 56.66% among the females, significantly higher than that among the males (48.23%, P = 0.03). The heritability in the first-degree relatives was 138% +/- 7%, and the concordance rate of monozygotic twins was 100%. The significant risk factors were female gender (P = 0.03), body mass index (P < 0.01) and diet (P < 0.008). The history of hypertension, hyperlipidemia, and diabetes were correlated to gallstone disease (P = 0.008, < 0.008, and 0.03 respectively). Serum HDL-Ch and ApoA1 concentrations were lower in the stone group than in the non-stone group (P = 0.003 and 0.005 respectively). There were no significant differences in TCh, TG, LDL-Ch, and ApoB between the 2 groups., Conclusion: Genetic factors play a major role in the pathogenesis of familial gallstone disease, characterized by autosomal dominant inheritance. Female gender, obesity, diet, hypertension, hyperlipidemia, diabetes may be the risk factors of gallstone disease. Dyslipidemia is a characteristic of gallstone disease.

Objective: To study the characteristics of inheritance and epidemiology of gallstone disease in one pedigree., Methods: A gallbladder disease-specific questionnaire was administered to all family members to ascertain histories of cholecystectomy and other medical conditions as well as anthropometrical data. Laboratory examination and ultrasonography were performed to determine the existence of gallstone., Results: One hundred and thirteen members of four generations in the index family were enrolled in the study. The prevalence of gallstone in females (34.48%) was higher than in males (23.64%) but with no significant difference. The prevalence in the second and third generations (52%) was higher than in others (20%) (P < 0.05). The heritability and standard error showed as 86.38% +/- 46.46% in I generations. Body mass index, histories of hypertension, hyperlipidemia and blood glucose were positively related to gallstone disease (P = 0.012, < 0.01, 0.017, 0.043, respectively) in this family. Gallstone disease was not significantly related to history of diabetes, daily alcohol or diet habit. Plasma cholesterol and triglyceride levels were not correlated with gallstone disease., Conclusion: Gallstone disease presented aggregation in the family and was in accordance with the characteristics of autosomal dominant inheritance. Being female, obesity, hypertension and history of hyperlipidemia might serve as risk factors to this family.
