Background: Strict quarantine is an effective measure to prevent the spread of the Coronavirus disease (COVID-19) pandemic, but it probably increases the risk of anxiety and depression. We aimed to evaluate the anxiety and depression among quarantined college students at school during the COVID-19 pandemic and investigate whether gastrointestinal discomfort related-factors and skipping breakfast lead to increased risk of anxiety and depression. Methods: 384 quarantined college students in Shanghai China were recruited in this cross-sectional study from April 5th to May 29th, 2022. Generalized Anxiety Disorder (GAD-7) and Patient Health Questionnaire (PHQ-9) were used to assess anxiety and depression, respectively.Results: The prevalence of anxiety and depression were 56.8% and 62.8%, respectively. Longer quarantine duration, higher education level, skipping breakfast, stomachache or abdominal pain, and nausea or dyspepsia were the risk factors for anxiety. Moreover, longer quarantine duration, being woman, skipping breakfast, stomachache or abdominal pain, and nausea or dyspepsia increased the risk of depression. Notably, regularly physical exercising and taking positive attitude towards COVID-19 can reduce the risk of anxiety and depression. Conclusions: More attention should be paid to anxiety and depression of quarantined college students and universities should provide timely psychological monitoring and intervention services to mitigate the impact of negative emotions on students. And effectively relieving gastrointestinal symptoms, insisting on eat breakfast, regularly exercising, and taking a positive attitude towards to COVID-19 might contribute to preventing the anxiety and depression for those college students experiencing a long-term quarantine.

In the process of combating the coronavirus disease 2019 (COVID-19) epidemic, medical personnel were at the forefront of the fight. As the future medical workforce, medical students often experienced firsthand how their seniors and teachers had to commit to working hard in combating the epidemic. Many were directly involved in the front line of the fight and that experience could easily have affected their intention to seek employment in a medically related career.The study intended to evaluate the impact of the COVID-19 pandemic on Chinese medical students' employment intentions and the factors associated with them to put forward relevant suggestions to provide a basis for medical education in the future.The research team conducted a cross-sectional study, using an anonymous online questionnaire.The study took place in many provinces and cities in China and was conducted in an online questionnaire.Participants were 1114 college students studying clinical medicine, college students studying nursing, and students interning during standardized resident training, medical interns.The participants completed a self-administered questionnaire, which investigated their psychological statuses related to anxiety and depression as well as COVID-19's impact on their intentions related to job searches, regarding their willingness to engage in clinical or basic research in epidemic-related specialties and epidemic-related work.Compared to college students studying clinical medicine, the employment intentions of nursing students and medical interns were more vulnerable to the epidemic. Females and nursing students were more reluctant to choose clinical work, and the choice was associated with depression. Nursing college students and medical interns were significantly less willing to engage in infection medicine, respiratory medicine, and intensive care medicine (all P.001). Medical students with a bachelor's degree and postgraduate degrees were significantly less willing to engage in infection medicine and respiratory medicine (all P.001), but medical students from regions with stable epidemics were more willing to engage in intensive care medicine. Medical students with a bachelor's degree were significantly less likely to be involved in epidemiology-related work than undergraduate students, and students from severe epidemic regions were significantly less willing to work in isolation wards or to go to Wuhan as volunteers.Participants' psychological statuses related to anxiety and depression, genders, degrees, current educational statuses, and regions affected employment intentions during the epidemic.

Recently, the healing of chronic wounds such as extensive burns has become a serious and intractable clinical problem. Avoiding wound infection and retaining an appropriate level of moisture around wounds are significant challenges in wound care. Herein, a dual-network hydrogel composed of sodium alginate (SA) and platelet-rich plasma (PRP) was designed to facilitate the wound healing. The preparation of hydrogel was achieved through a simple one-step thrombin activation process. The morphological characterization results revealed the three-dimensional network structure of the hydrogel. Then, certain levels of epidermal growth factor (EGF) and vascular endothelial growth factor (VEGF) were detected in phosphate buffer solution (PBS) cultured hydrogel, which led to the possibility of cell proliferation and vascular regeneration. When topically applied to the wound skin of rats, the hydrogel presented high wound closure effectiveness. In conclusion, this strategy provides a simple and feasible approach to overcoming the shortcomings of conventional wound dressings.

Positive retests of COVID-19 represent a public health concern because of the increased risk of transmission. This study explored whether factors other than the nucleic acid amplification test (NAAT) contribute to positive retest results. Patients with COVID-19 admitted to the Guanggu district of the Hubei Maternal and Child Health Hospital between February 17 and March 28, 2020, were retrospectively included. The patients were grouped into the negative (n = 133) and positive (n = 51) retest groups. The results showed that the proportion of patients presenting with cough was higher (P P = 0.018) in the positive than in the negative retest group. The positive retest group showed shorter durations between symptom onset and hospitalization (P P = 0.033). The positive retest group had higher basophil counts (P = 0.023) and direct bilirubin (P = 0.032) and chlorine concentrations (P = 0.023) but lower potassium concentrations (P = 0.001) than the negative retest group. Multivariable regression analysis showed that coughing (OR = 7.59, 95% CI 2.28–25.32, P = 0.001) and serum chloride concentrations (OR = 1.38, 95% CI 1.08–1.77, P = 0.010) were independently associated with a positive retest result. Coughing and serum chloride concentrations were independent risk factors for positive NAAT retest results. Patients with a hospital stay of

The limitations in discriminating preablation disease-active status of differentiated thyroid carcinoma (DTC) still represent a major challenge to radioiodine dose management. Cytokines, the small protein signaling molecules that constitute the thyroid tumor microenvironment, play significant roles in the facilitation of intercellular communication and the control of tumorigenesis. Also, more attention should be paid to the molecular events within the innate and adaptive immune systems that occur after the organism being exposed to ionizing radiation. Therefore, we implemented a study of 260 patients with DTC in thyroid hormone withdrawal status who were treated with total thyroidectomy to explore the relationship between cytokines and recurrence/active disease status. Besides, we made a cross-sectional study to analyze pre- and post-ablation serum concentration of cytokines of 86 patients with DTC. There was a relationship between clinicohistopathological characteristics of patients with DTC and the presence of cytokines. It is noteworthy that patients with recurrence/active disease were at a higher serum interleukin-2 receptor (IL-2R) level than the disease-free patients (213.59 ± 75.43 pg/ml vs. 186.80 ± 77.40 pg/ml, P = 0.005). Positive correlation was observed between serum IL-2R and thyroglobulin (Tg) (P = 0.003). We also found significant changes in the cytokine profile after radioiodine ablation, including the decrease of tumor necrosis factor-α and IL-8 (P < 0.001, P < 0.001, respectively), and increase of IL-2R (P < 0.001). Thus, we suggest that serum IL-2R may assist in evaluating the disease status during the post-thyroidectomy follow-up and radioiodine therapy has an immunoregulatory effect on serum cytokines.

Introduction: To investigate the effects and influencing factors of the COVID-19 epidemic on the employment intention of resident physicians in China. Methodology: 409 questionnaires were statistically analyzed after removing the missing values. We used the Chi-Square test for single-factor analysis and logistic regression analysis for multivariate analysis. The questions include the residents' employment intention and their willingness to engage in epidemic-related subspecialties and participate in epidemic-related work. Results: Residents of severe and high-risk epidemic regions had much lower employment intentions than those of stable epidemic regions (OR = 1.917, 95% CI: 1.024, 3.591, p = 0.042). The higher the Center for Epidemiologic Studies Depression Scale (CES-D) score, the more susceptible was the resident's employement intention (OR = 1.085, 95% CI: 1.044, 1.128, p < 0.001). Residents from severe and high-risk epidemic regions were more willing to participate in clinical work (OR = 4.263, 95% CI: 1.892, 9.604, p < 0.001), and the higher the CES-D score, the lower was the proportion of residents willing to choose clinical work (OR = 0.941, 95% CI: 0.893, 0.992, p = 0.023). Residents from severe epidemics and high-risk provinces were less willing to participate in respiratory medicine (χ2 = 5.070, p = 0.027) and critical care medicine (χ2 = 7.046, p = 0.011). Compared to residents with bachelor’s degrees, residents with master’s and doctoral degrees were less willing to participate in isolation wards (OR = 1.831, 95% CI: 1.122, 2.990, p = 0.016). Residents in epidemic-related current rotation departments were less willing to go to Wuhan as volunteers (OR = 2.197, 95% CI: 1.110, 4.347, p = 0.024). Conclusions: The COVID-19 outbreak had a negative impact on the job intentions of Chinese residents in general.

The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleic acid test is currently the gold standard for diagnosing coronavirus disease 2019 (COVID-19). This disease requires high-quality viral nucleic acid tests, and selecting the type of specimen from patients, who are at different disease stages, to use in the nucleic acid test is challenging. This article reports in detail the diagnosis and treatment process for two patients with confirmed COVID-19 and analyzes the results of the SARS-CoV-2 nucleic acid tests that were used for different types of specimens (sputum from deep cough, nasopharyngeal swab, and feces). The nucleic acid testing results of sputum from deep cough showed the best performance for positive detection. Our findings provide a reference for selecting the most suitable specimen for the clinical diagnosis of COVID-19 and improving the positive detection rate.

Background Novel severe acute respiratory syndrome coronavirus 2 causes the novel coronavirus disease (COVID-19) in humans, which has spread rapidly worldwide. Most critical cases of COVID-19 are accompanied by complicated chronic underlying diseases. This retrospective study aims to analyze the clinical characteristics of COVID-19 patients with chronic underlying diseases.Methods A total of 1,183 COVID-19 patients were divided into the chronic underlying disease (CUD, n = 538) group and the non-underlying disease (non-CUD, n = 645) group. The clinical characteristics and outcomes were collected and compared between the two groups.Results There were significant differences in age, weight, and SPO2 on admission between the CUD and non-CUP groups. The ratio of severe cases in the CUD group was higher than that in the non-CUD group (χ2 = 35.58, p-value 2 = 5.57, p-value = 0.018). No statistical difference in mortality between the CUD (n = 18) and non-CUD groups (n = 13). All surviving patients were cured and discharged. A total of 33 patients had a positive re-examination result for nucleic acid test one week after discharge, including 14 patients with underlying diseases and 19 patients without underlying diseases. Conclusion: COVID-19 patients with underlying diseases had poorer clinical conditions and had a longer hospital stay, but after active treatment, the mortality had not increased significantly.

Background: Currently, COVID-19 is a global pandemic disease that has caused a large number of infections worldwide. Reports of COVID-19 cases are not uncommon, but there is no report that SAMS-CoV-2 RNA test results for grandma and grandchildren in family aggregation infections are completely different.Case presentation: A 6-year-old boy's chest CT indicated lung infection, but SAMS-CoV-2 RNA test was negative. His grandmother's imaging showed lung inflammation absorption, and nucleic acid test was positive. Conclusions: Children and the elderly people have different clinical manifestations during the course of SAMS-CoV-2 infection, it is challenging to identify whether they are infectious. Therefore, the diagnosis of COVID-19 requires a combination of multiple detection measures, including clinical features, imaging features, and SAMS-CoV-2 RNA test results.Keywords: COVID-19; SAMS-CoV-2 RNA test; Imaging diagnosis; Case report

This study was aimed at revealing the dynamic regulation of mRNAs, long noncoding RNAs (lncRNAs), and microRNAs (miRNAs) in hepatocellular carcinoma (HCC) and to identify HCC biomarkers capable of predicting prognosis. Differentially expressed mRNAs (DEmRNAs), lncRNAs, and miRNAs were acquired by comparing expression profiles of HCC with normal samples, using an expression data set from The Cancer Genome Atlas. Altered biological functions and pathways in HCC were analyzed by subjecting DEmRNAs to Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analysis. Gene modules significantly associated with disease status were identified by weighted gene coexpression network analysis. An lncRNA-mRNA and an miRNA-mRNA coexpression network were constructed for genes in disease-related modules, followed by the identification of prognostic biomarkers using Kaplan-Meier survival analysis. Differential expression and association with the prognosis of 4 miRNAs were verified in independent data sets. A total of 1220 differentially expressed genes were identified between HCC and normal samples. Differentially expressed mRNAs were significantly enriched in functions and pathways related to “plasma membrane structure,” “sensory perception,” “metabolism,” and “cell proliferation.” Two disease-associated gene modules were identified. Among genes in lncRNA-mRNA and miRNA-mRNA coexpression networks, 9 DEmRNAs and 7 DEmiRNAs were identified to be potential prognostic biomarkers. MIMAT0000102, MIMAT0003882, and MIMAT0004677 were successfully validated in independent data sets. Our results may advance our understanding of molecular mechanisms underlying HCC. The biomarkers may contribute to diagnosis in future clinical practice.

BACKGROUND As a serious public health event, the coronavirus disease 2019(COVID-19) pandemic is raging around the world. Whether it has an effect on medical students' employment intention is unknown. OBJECTIVE To explore the impact of COVID-19 on the employment intention of Chinese medical students and its associated factors. METHODS An electronic questionnaire was designed to conduct an anonymous online convenient sampling survey for medical students in China. 1163 medical students from thirty-one different provinces of different academic degrees, current educational status, and regions were surveyed. The questionnaire investigated the overall impression of the impact of the COVID-19 epidemic on medical students’ employment intentions, the willingness to engage in clinical or basic research after graduation, the willingness to engage in epidemic-related specialties after graduation, and the willingness to participate in epidemic-related work. RESULTS The medical students' employment intention was correlated with academic degree (ρ=0.09, P=.003), current educational status (ρ=0.10, P=.001), and geographical region (ρ=-0.07, P=.03). For choosing clinical work or scientific research, statistical significance was observed in gender (21=7.0, P=.008), degree (22=8.6, P=.01), and current educational status (22=65.0, P CONCLUSIONS The COVID-19 pandemic has a significant influence on the employment intention of Chinese medical students from different degrees, educational status and regions. More professional ethics education, preferential policies, and encouragement should be supplied to medical students.

Background Secretory leukocyte protease inhibitor (SPLI) was a secreted protein which belongs to a member of whey acidic protein four-disulfide core family. In breast cancer (BC) it may inhibit cell proliferation and promote cancer metastasis. In this study, a comprehensive bioinformatics analysis was performed to identify the expression and prognostic value of SLPI in breast cancer. Methods SLPI expression in breast cancer was analyzed in Oncomine online database, which was subsequently confirmed by quantitative PCR (qPCR) in 18 BC samples and western blotting in 26 BC samples. Breast cancer gene-expression miner v4.1 was used to access the expression level with clinicopathological parameters in breast cancer patients. The prognostic values of SLPI in breast cancer were evaluated using the PrognoScan database. Results Our results indicated that SLPI was downregulated in breast cancer than in normal tissues. SLPI expression was found to be negatively correlated with estrogen receptor (ER) and progesterone receptor (PR) status. SLPI expression level was decreased in negative basal-like status patients compared with positive basal-like status. Meanwhile, triple-negative breast cancer status positive correlated with SLPI. We confirmed a positive correlation between SLPI and interleukin 17 receptor B (IL17RB) express in breast cancer tissues via oncomine co-expression analysis. Ten proteins: Elastase, Granulin, Lipocalin, Defensin beta 103B, Defensin beta 103A, Tubulin, Heparin-binding EGF-like growth factor, Interleukin 6, Epidermal growth factor, Phospholipid scramblase 1 were determinate interactions with SLPI by STRING. Conclusion SLPI could as a biomarker to predict the prognosis values of breast cancer. However, further comprehensive study and mining more evidence are needed to clarify our results.

Purpose: To establish a computed tomography–based prognostic model for patients with hepatocellular carcinoma treated with transarterial chemoembolization. Materials and Methods: Using prospectively collected data from 195 consecutive patients with hepatocellular carcinoma who underwent chemolipiodolization at the Eastern Hepatobiliary Surgery Hospital between 2013 and 2016, we established a prognostic model based on hepatocellular carcinoma enhancement patterns on computed tomography scans to predict the outcome of transarterial chemoembolization. Furthermore, a histopathology analysis was performed on 108 different patients undergoing resection between 2014 and 2016 to identify whether there was a correlation between enhancement pattern and microvessel density. Results: The prognostic model classified hepatocellular carcinoma into 3 types: type I, which reached peak enhancement during the arterial phase and had a high mean microvessel density (101.5 vessels/0.74 mm2); type II, which reached peak enhancement during the portal venous or delayed phase and had an intermediate microvessel density (53.6 vessels/0.74 mm2); and type III, in which the tumor was insignificantly enhanced and had a low microvessel density (21.1 vessels/0.74 mm2). For type I, II, and III hepatocellular carcinoma, the post-transarterial chemoembolization 1-year tumor complete necrosis rates were 13.7%, 36.5%, and 0%, respectively ( P < .001), and the 3-year overall survival rates were 14.1%, 38.6%, and 0%, respectively ( P < .001). Conclusion: Our results indicate that hepatocellular carcinoma type is an independent predictor of complete necrosis and overall survival
