Abstract
Recent research revealed methionine metabolism as a key mediator of tumor initiation and immune evasion. However, the relationship between methionine metabolism and tumor microenvironment (TME) in lung adenocarcinoma (LUAD) remains unknown. Here, we comprehensively analyzed the genomic alterations, expression patterns, and prognostic values of 68 methionine-related regulators (MRGs) in LUAD. We found that most MRGs were highly prognostic based on 30 datasets including 5024 LUAD patients. Three distinct MRG modification patterns were identified, which showed significant differences in clinical outcomes and TME characteristics: The C2 subtype was characterized by higher immune score, while the C3 subtype had more malignant cells and worse survival. We developed a MethScore to measure the level of methionine metabolism in LUAD. MethScore was positively correlated with T-cell dysfunction and tumor-associated macrophages (TAMs), indicating a dysfunctional TME phenotype in the high MethScore group. In addition, two immunotherapy cohorts confirmed that patients with a lower MethScore exhibited significant clinical benefits. Our study highlights the important role of methionine metabolism in modeling the TME. Evaluating methionine modification patterns will enhance our understanding of TME characteristics and can guide more effective immunotherapy strategies.

Abstract
The current study analyzed the mutation rate of BRAFV600E in papillary thyroid carcinoma patients and the correlation between BRAFV600E mutation and aggressive biological behavior of papillary thyroid carcinoma. A total of 160 patients with papillary thyroid carcinoma who underwent surgical treatment in the Affiliated Cancer Hospital of Zhengzhou University from October 2020 to November 2021 were retrospectively included. All patients underwent BRAFV600E gene detection. There were 37 males and 123 females, with a mean age of (46.5±11.1) years. The mutation rate of BRAFV600E was 86.3% (138/160). There was no significant correlation between the mutation of BRAFV600E and aggressive factors such as age (P=0.917), single focal/multifocal tumor (P=0.673), tumor size (P=0.360), tumor invasion (P=0.150) and regional lymph node metastasis (P=0.406). Therefore, for papillary thyroid cancer, mutations in a single gene like BRAFV600E fail to determine more active diagnosis and treatment.

Abstract
Objective: To understand the comparability of noise measurement results of various occupational hygiene technical service organizations in Guangdong Province by conducting inter-laboratory comparison of measuring instruments and personnel operation. Methods: In October 2020, the instrument comparison and personnel comparison among 91 occupational hygiene technical service organizations engaged in noise measurement in Guangdong Province were carried out in the form of fixed-point measurement and simulated workplace measurement, and the results were analyzed and evaluated by using the robust z-ratio score. Results: In the instrument comparison, 6 organizations had 1 or 2 outliers in their z-ratio scores, 2 organizations had 2 problematic values in their z-ratio scores, and a total of 8 organizations (accounting for 8.8%) were judged as unqualified; A total of 83 organizations (accounting for 91.2%) with satisfactory z-ratio scores or only one problematic value were judged as qualified. In the personnel comparison, there were 11 organizations with 1 or 2 outliers in the z-ratio score, and 1 organization with 2 problematic values in the z-ratio score. A total of 12 organizations (13.2%) were judged as unqualified and 79 organizations (accounting for 86.8%) with satisfactory z-ratio scores or only one problematic value were judged as qualified. Through comprehensive judgment, 20 organizations (22.0%) were judged as unqualified, and 71 organizations (78.0%) were judged as qualified. There was no statistically significant difference in the qualified rates of instrument comparison results, personnel comparison results and comprehensive evaluation results of non-private organizations and private organizations (P>0.05). There was no significant difference in the qualified rates of instrument comparison results and comprehensive evaluation results of qualified organizations and unqualified organizations (P>0.05), there was significant difference in the qualified rate of personnel comparison results (P<0.05) . Conclusion: The noise measurement results of some occupational health technical service organizations in Guangdong Province are generally comparable. To carry out inter-laboratory comparison of noise instrument performance and personnel operation ability of occupational hygiene technical service organizations, can comprehensively evaluate the testing process of each organization and find out the problems existing in each organization.

Abstract
OBJECTIVE This study examined the prevalence of exposure to secondhand smoke, its correlates and its association with quality of life (QOL) among pregnant and postnatal Chinese women. DESIGN This was a multicentre, cross-sectional study. SETTING Participants were consecutively recruited from eight tertiary hospitals located in eight municipalities or provinces in China. PARTICIPANTS A total of 1140 women were invited to join this study and 992 (87.02%) completed all measures. PRIMARY AND SECONDARY OUTCOME Measures women's secondhand smoking behaviour (frequency and location of exposure to secondhand smoking), and their QOL measured by the WHO Quality of Life Questionnaire. RESULTS A total of 211 women (21.3%, 95% CI 18.7% to 23.8%) had been exposed to secondhand smoking. Exposure to secondhand smoking was most common in public areas (56.4%), and residential homes (20.5%), while workplaces had the lowest rate of exposure (13.7%). Women with physical comorbidities were more likely to report secondhand smoking exposure, while older women, women living in urban areas, those with college or higher education level, and women in their second trimester were less likely to report exposure to secondhand smoking. Network analysis revealed that there were six significant links between secondhand smoke and QOL items. The strongest negative edge was the connection between secondhand smoke and QOL9 ('physical environment health', edge weight=-0.060), while the strongest positive edge was the connection between secondhand smoke and QOL3 ('pain and discomfort', edge weight=0.037). CONCLUSION The prevalence of exposure to secondhand smoking is becoming lower among pregnant and postnatal women in China compared with findings reported in previous studies. Legal legislation should be maintained and promptly enforced to establish smoke-free environments in both public and private urban/rural areas for protection of pregnant and postnatal women, especially those who are physically vulnerable and less educated.

Abstract
Non-small cell lung cancer (NSCLC) is one of the most general malignant tumors. The overexpression of epidermal growth factor receptor (EGFR) is a common marker in NSCLC, and it plays an important role in the proliferation, invasion, and metastasis of cancer cells. At present, drugs developed with EGFR as a target suffer from drug resistance, so it is necessary to study new compounds for the treatment of NSCLC. The active substance in green tea is EGCG, which has anti-cancer effects. In this study, we synthesized dimeric-(-)-epigallocatechin-3-gallate (prodelphinidin B-4-3,3‴-di-O-gallate, PBOG), and explored the effect of PBOG on lung cancer cells. PBOG can inhibit the proliferation and migration of NCI-H1975 cells, promote cell apoptosis, and inhibit cell cycle progression. In addition, PBOG can bind to the EGFR ectodomain protein and change the secondary structure of the protein. At the same time, PBOG decreases the expression of EGFR and downstream protein phosphorylation. Animal experiments confirmed that PBOG can inhibit tumor growth by inhibiting EGFR phosphorylation. Collectively, our study results show that PBOG may induce a decrease in intracellular phosphorylated EGFR expression by binding to the EGFR ectodomain protein, thereby inducing apoptosis and inhibiting cell cycle progression, thus providing a new strategy to treat lung cancer.

Abstract
Background The role of beta-blockers in acute myocardial infarction patients without heart failure and with preserved left ventricular ejection fraction (LVEF ≥ 50%) is unknown. Our study aimed to retrospectively analyze the associations of beta-blockers on such patients. Methods This is a multicenter, retrospective study. After screening 5,332 acute myocardial infarction patients, a total of 2519 patients without heart failure and with LVEF ≥ 50% were included. The patients were divided into two groups: the prescribed (n = 2049) and unprescribed (n = 470) beta-blockers group. The propensity score inverse probability treatment weighting was used to control confounding factors. We analyzed the associations between beta-blockers and outcomes in the short-term (1-year) and long-term (median, 3.61 years). Results The primary outcome was all-cause mortality. The secondary outcomes were all-cause rehospitalization, cardiac death, recurrent myocardial infarction, new-onset heart failure rehospitalization. This study shows no statistically significant association between discharged with beta-blockers and all-cause mortality, either in the short-term [IPTW Adjusted, HR 1.02; 95%CI 0.43–2.40; P = 0.966] or long-term [IPTW Adjusted, HR 1.17; 95%CI 0.70–1.94; P = 0.547]. Discharged with beta-blockers was significantly associated with a reduced risk of short-term recurrent myocardial infarction [IPTW Adjusted, HR 0.44; 95%CI 0.20–0.97; P = 0.043], but there was no long-term relationship [IPTW Adjusted, HR 1.11; 95%CI 0.61–2.03; P = 0.735]. Other outcomes, such as new-onset heart failure rehospitalization and all-cause rehospitalization, were not observed with meaningful differences in either the short- or long-term. The results of sensitivity analysis were consistent with this. Conclusions Beta-blockers might be associated with a reduced risk of recurrent myocardial infarction in patients without heart failure and with preserved left ventricular ejection fraction after acute myocardial infarction, in the short term. Beta-blockers might not be related to all-cause mortality in those patients, either in the short-term or long-term.

Abstract
Background The duration of beta‐blocker therapy in patients without heart failure (HF) or left ventricular systolic dysfunction after acute myocardial infarction (AMI) is unclear. Hypothesis Continuous beta‐blocker therapy is associated with an improved prognosis. Methods This is a prospective, multicenter, cohort study. One thousand four hundred and eighty‐three patients eventually met the inclusion criteria. The study groups included the continuous beta‐blocker therapy group (lasted ≥6 months) and the discontinuous beta‐blocker therapy group (consisting of the no‐beta‐blocker therapy group and the beta‐blocker therapy <6 months group). The inverse probability treatment weighting was used to control confounding factors. The study tried to learn the role of continuous beta‐blocker therapy on outcomes. The median duration of follow‐up was 13.0 months. The primary outcomes were cardiac death and major adverse cardiovascular events (MACE). The secondary outcomes were all‐cause death, stroke, unstable angina, rehospitalization for HF, and recurrent myocardial infarction (MI). Results Compared with discontinuous beta‐blocker therapy, continuous beta‐blocker therapy was associated with a reduced risk of unstable angina, recurrent MI, and MACE (hazard ratio [HR]: 0.51; 95% CI: 0.32–0.82; p = 0.006); but this association was not available for cardiac death (HR: 0.57; 95% CI: 0.24–1.36; p = 0.206). When compared to the subgroups of no‐beta‐blocker therapy and beta‐blocker therapy <6 months, respectively, continuous beta‐blocker therapy was still observed to be associated with a reduced risk of unstable angina, recurrent MI, and MACE. Conclusions Continuous beta‐blocker therapy was associated with a reduced risk of unstable angina or recurrent MI or MACE in patients without HF or left ventricular systolic dysfunction after AMI.

Abstract
BACKGROUND With the implementation of health care reforms in China, primary care is on a journey to provide care for most patients with type 2 diabetes. While Chinese general practitioners (GPs) have described challenges in communication with diabetes patients in their daily practice, little is known about patients' experiences in communicating with their GPs. METHODS Five focus groups (of 4-5 participants each) were used to explore views from patients with type 2 diabetes. Purposive sampling was used to recruit a spread of participants from general practices in Guangzhou city, China. Focus groups were audio-recorded, transcribed, and thematically analyzed using the Framework Method. RESULTS Ten males and 12 female patients from five general practices participated in focus group discussions, with a mean age of 57.3 years and 7.3 years of diabetes duration. Five main themes emerged: patients' understanding about diabetes, diabetes medication, communication with GPs, physician-patient relationships, and healthcare systems and context. Patients generally searched for information on the internet, but they weren't always sure if it was trustworthy. Several communication needs were described by diabetes patients, such as explanation of blood glucose monitoring, medication information support, communication in the risk of diabetes complications and cardiovascular disease, and language barriers. Communication was frequently brief and not tailored to their concerns, and some described being scolded or panicked by GPs. Participants acknowledged the pressures within the health system, such as short consultation times, an incoherent GP-hospital interface and high demand. CONCLUSIONS Key issues from the patients' perspective for the development of primary care based management of diabetes in China were identified. People with type 2 diabetes require more access to trustworthy diabetes information and wish for better channels of communication with their GPs. Strategies may be required to improve GPs' communication skills with their patients that also consider the context of the wider health system environment in China.

Abstract
OBJECTIVE Excessive Internet use is a common health problem globally. This study aimed to assess the prevalence, correlates, and network structure of Internet addiction symptoms (Internet addiction hereafter) among Chinese pregnant and postpartum women. METHODS This was a multicenter cross-sectional study using Internet Addiction Test (IAT) and the World Health Organization Quality of Life Questionnaire (WHOQOL-BREF) to evaluate Internet addiction and quality of life (QOL), respectively. Univariate analyses, multivariate logistic regression analyses, and network analyses were performed. RESULTS Of a total of 1,060 women who completed the study, 320 (30.19%, 95% CI=27.42%-32.96%) women reported Internet addiction during or after pregnancy. Women with previous adverse pregnancy experiences (OR=1.831, P=0.001) and physical comorbidities (OR=1.724, P=0.004) had a higher likelihood of developing Internet addiction. Internet addiction was significantly associated with poor QOL in all domains. Network analyses revealed that IAT item 16 (request an extension for longer time spent online) was the most central symptom in the analyses, and also one of the strongest bridging symptoms linking the Internet addiction and QOL communities. LIMITATIONS This was a cross-sectional study, all study findings were based on self-reported data, and possible recall bias and selection bias may exist. CONCLUSION Internet addiction is common among Chinese pregnant and postpartum women, and is significantly associated with lower QOL. Effective strategies, especially focusing on central symptoms, are needed to reduce the impact of Internet addiction and improve QOL in pregnant and postpartum women.

Abstract
The risk of plague epidemics and relapse of various types of plague foci persists in Inner Mongolia Autonomous Region. For Marmota sibirica plague foci, the animal plague has not been found but antibody has been detected positive. Nowadays, Marmota sibirica has been increasing in population and distribution in China. In bordering countries Mongolia and Russia, the animal plague has been continuously prevalent. For Spermophilus dauricus plague foci, the animal plague has been taken place now and then. Compared to the above foci, the animal plague is most prevalent in Meriones unguiculatus plague foci and frequently spread to humans. Due to higher strain virulence and historical disaster in Marmota sibirica plague foci and Spermophilus dauricus plague foci, plague prevention and control should be strengthened on these foci. In addition to routine surveillance, epidemic dynamics need to be further monitored in these two foci, in order to prevent their relapse and spread to humans.

Abstract
Objective: To investigate the diagnosis, treatment and prognosis of ureteral endometriosis with hydronephrosis. Methods: A retrospective study was performed of 92 cases diagnosed as ureteral endometriosis with surgery confirmed in Peking University First Hospital from January 2000 to January 2021. Results: The incidence of ureteral endometriosis was 0.9% (92/10 222), with an average age of (40.0±6.0) years. Among 92 cases, urological symptoms and pelvic pain including dysmenorrheal, periodic abdominal pain were the main forms of clinical characteristics, while 11 patients (12%, 11/92) were asymptomatic. All patients with ureteral endometriosis had hydronephrosis and hydroureter before surgery, hydronephrosis were left sided in 48 (52%, 48/92) patients, right sided in 39 (42%, 39/92) patients, both sided in 5 (5%,5/92) patients. The distal and middle sections of ureteral obstructions existed in 73 (79%, 73/92) patients and 19 (21%, 19/92) patients, respectively. Out of the 92 ureteral lesions 71 (77%, 71/92) patients were extrinsic lesions, 21 (23%, 21/92) patients presented intrinsic lesions. Of the 38 cases who took preoperative radionuclide renal dynamic imaging examination, there were 6 (16%, 6/38) cases of mildly damaged, 7 (18%, 7/38) cases of moderately dameged, 14 (37%, 14/38) cases of severely damaged, and 11 (29%, 11/38) cases of normal renal function. Laparotomy was decided in 25 (27%, 25/92) patients, and laparoscopic surgery in 67 (73%, 67/92) patients. In cases of ureteral surgery, ureterolysis, partial ureteral resection and ureterocystoneostomy, partial ureteral resection and end-to-end ureteral anastomosis and nephroureterectomy were undertaken in 52 (57%, 52/92), 20 (22%, 20/92), 12 (13%, 12/92) and 8 (9%, 8/92) patients separately. The median follow up was 108 months (range: 6 to 240 months). During the follow-up period, 68 (87%, 68/78) patients took urinary ultrasound after surgery, and 60 (88%, 60/68) cases of hydronephrosis disappeared, and 8 (12%, 8/68) cases were better than before. Conclusion: Most of the patients with ureteral endometriosis are impaired with renal function, and early surgical treatment could effectively relieve urinary obstruction and promote the recovery of renal function.

Abstract
BACKGROUND The surface topography index (STI) has great potential in both routine computed tomography (CT) scan and emerging optical imaging systems. However, the diagnostic accuracy and stability of the STI as a deformity severity assessment index has not been fully confirmed. Therefore, the aim of the present study was to determine the diagnostic performance of the STI as a novel deformity severity assessment index for pectus excavatum. METHODS The present study consisted of 722 chest CT images from a single center. The standard CT index (CTI) and STI were calculated for all patients. The between-group difference and the level of compliance between the CTI and STI was analyzed by t-test and Pearson correlation. The diagnostic value and optimum discriminatory values of the CTI and STI were calculated by a receiver-operating characteristic (ROC) curve and DeLong's test. RESULTS The distributions of the CTI and STI were similar and showed a slight overlap between the pectus excavatum (PE) and non-PE groups. Both the CTI and STI significantly differed between the 2 groups (P<0.001). The STI demonstrated a strong Pearson correlation with the CTI (r=0.91, 95% confidence interval: 0.88-0.91, P<0.001). The ROC curves showed that STI =1.58 (sensitivity: 0.93, specificity: 0.95) could be considered equivalent to CTI =2.72 (sensitivity: 0.93, specificity: 0.97) as the optimum discriminatory values. DeLong's test showed no significant difference in the ROC curve results between the CTI and STI (Z=0.90, P=0.37). CONCLUSIONS The STI has comparative discrimination ability in PE diagnosis and deformity severity assessment when used with the standard CTI. The STI as a novel index is not only an ideal evaluation metric of PE deformity but also an objective trait for PE patients just as weight and height for everyone.

Abstract
Lung cancer is one of the most commonly occurring cancer mortality worldwide. The epidermal growth factor receptor (EGFR) plays an important role in cellular functions and has become the new promising target. Natural products and their derivatives with various structures, unique biological activities, and specific selectivity have served as lead compounds for EGFR. D-glucose and EGCG were used as starting materials. A series of glucoside derivatives of EGCG (7-12) were synthesized and evaluated for their in vitro anticancer activity against five human cancer cell lines, including HL-60, SMMC-7721, A-549, MCF-7, and SW480. In addition, we investigated the structure-activity relationship and physicochemical property-activity relationship of EGCG derivatives. Compounds 11 and 12 showed better growth inhibition than others in four cancer cell lines (HL-60, SMMC-7721, A-549, and MCF), with IC50 values in the range of 22.90-37.87 μM. Compounds 11 and 12 decreased phosphorylation of EGFR and downstream signaling protein, which also have more hydrophobic interactions than EGCG by docking study. The most active compounds 11 and 12, both having perbutyrylated glucose residue, we found that perbutyrylation of the glucose residue leads to increased cytotoxic activity and suggested that their potential as anticancer agents for further development.

Abstract
BACKGROUND China has more ascertained cases of diabetes than any other country. Much of the care of people with type 2 diabetes (T2DM) in China is managed by GPs and this will increase with the implementation of health care reforms aimed at strengthening China's primary health care system. Diabetes care requires effective communication between physicians and patients, yet little is known about this area in China. We aimed to explore the experiences of Chinese GPs in communicating with diabetes patients and how this may relate to communication skills training. METHODS Focus groups with Chinese GPs were undertaken. Purposive sampling was used to recruit 15 GPs from Guangzhou city in China. All data were audio-recorded and transcribed. A thematic analysis using the Framework Method was applied to code the data and identify themes. RESULTS Seven males and 8 females from 12 general practices attended 4 focus groups with a mean age of 37.6 years and 7.5 years' work experience. Four major themes were identified: diversity in diabetic patients, communication with patients, patient-doctor relationship, and communication skills training. GPs reported facing a wide variety of diabetes patients in their daily practice. They believed insufficient knowledge and misunderstanding of diabetes was common among patients. They highlighted several challenges in communicating with diabetes patients, such as insufficient consultation time, poor communication regarding blood glucose monitoring and misunderstanding the risk of complications. They used terms such as "blind spot" or "not on the same channel" to describe gaps in their patients' understanding of diabetes and its management, and cited this as a cause of ineffective patient-doctor communication. Mutual understanding of diabetes was perceived to be an important factor towards building positive patient-doctor relationships. Although GPs believed communication skills training was necessary, they reported rarely received this. CONCLUSIONS Chinese GPs reported facing challenges in communicating with diabetes patients. Some of these were perceived as being due to the patients themselves, others were attributed to system constraints, and some were seen as related to a lack of clinician training. The study identified key issues for the development of primary care-based management of diabetes in China, and for developing appropriate communication skills training programs for the primary care workforce.

Abstract
OBJECTIVE To explore the dynamic expression of programmed cell death-1 (PD-1) and its ligand PD-L1 at the maternal-fetal interface of mice post-infection with Toxoplasma gondii at early pregnancy and examine its interaction with interferon-γ (IFN-γ). METHODS A total of 20 mice at day 0 of pregnancy were randomly assigned into 4 groups, including the 12-day pregnancy control group (12 dpn group), 12-day pregnancy and infection group (12 dpi group), 18-day pregnancy control group (18 dpn group) and 18-day pregnancy and infection group (18 dpi group), respectively. On the 6th day of the pregnancy, mice in the 12 dpi and 18 dpi groups were injected intraperitoneally with 150 tachyzoites of the T. gondii PRU strain, while mice in the 12 dpn and 18 dpn groups were injected with the same volume of PBS. All mice in the four groups were sacrificed on 12th and 18th day of the pregnancy, and the number of placenta and fetus was counted and the weight of placenta and fetus was measured. Then, the placental and uterine tissues of the pregnant mice in each group were sampled for pathological examinations. The mRNA expression of PD-1, PD-L1, T. gondii surface antigen SAG-1 and IFN-γ genes was quantified using a quantitative real-time PCR (qPCR) assay, and the correlation between PD-1 and IFN-γ expression was examined. In addition, the 12 dpn group, 12 dpi group, 18 dpn group, 18 dpi group, PBS negative control of the 12 pdi group and PBS negative control of the 18 dpi group were assigned, and the PD-1 expression was determined in the uterine and placenta tissues of the pregnant mice. RESULTS Adverse pregnant outcomes were seen in mice in the 12 dpi and 18 dpi groups, including placental dysplasia and fetal maldevelopment, and the placental weights and fetal body weights were significantly lower in mice in the 12 dpi and 18 dpi groups than those in the 12 dpn and 18 dpn groups (t = 5.52, 11.44, 12.63 and 11.67, all P < 0.01). The histopathological examinations showed that the decidua and junctional regions of the placental tissues were loosely connected in the 12 dpi and 18 dpi groups, and a large number of inflammatory cells infiltration and congestion were seen in the placental and uterine tissues. qPCR assay detected significant differences in PD-1, PD-L1, IFN-γ and SAG-1 expression in the placental and uterine tissues among the 12 dpn, 12 dpi, 18 dpn and 18 dpi groups (F = 22.48, 51.23, 9.61, 47.49, 16.08, 21.52, 28.66 and 238.90, all P < 0.05), and the PD-1, PD - L1, IFN - γ and SAG - 1 expression was all significantly higher in the placental and uterine tissues of mice in the 12 dpi group than in the 12 dpn group (all P values < 0.05). The PD-1 and PD-L1 expression was significantly lower in the placental tissues of mice in the 18 dpi group than in the 18 dpn group (all P values < 0.05), and the IFN-γ and SAG-1 expression was significantly higher in the placental and uterine tissues of mice in the 18 dpi group than in the 18 dpn group (all P values < 0.05), while the PD-1 and PD-L1 expression was significantly lower in the placental and uterine tissues of mice in the 18 dpi group than in the 12 dpi group (all P values < 0.05). Immunohistochemical staining showed PD-1 expression in the inflammatory cells of the placental tissues of mice in the 12 dpi group, and no apparent PD-1 expression in the 18 dpi group, while strongly positive PD-1 expression was found in the uterine epithelium of mice in the 12 dpi group, and mildly strong expression was in the 18 dpi group. In addition, the IFN-γ mRNA expression was positively correlated with the PD-1 mRNA expression in placental (rs = 0.99, P < 0.01) and uterine tissues of mice in the 12 dpi group (rs = 0.97, P < 0.01) and in placental (rs = 0.82, P < 0.01) and uterine tissues of mice in the 18 dpi group (rs = 0.81, P < 0.01). CONCLUSIONS Following T. gondii infection at early pregnancy, the PD-1 and PD-L1 expression shows a remarkable rise at middle pregnancy and a reduction at late pregnancy in placental and uterine tissues of mice, which appears the same tendency with IFN-γ expression during the same time period, and PD-1 expression positively correlates with IFN-γ expression. The dynamic expression of PD-1 and PD-L1 on the maternal-fetal interface of mice may be mutually mediated by IFN-γ induced by T. gondii infection.

Abstract
OBJECTIVE According to recent studies, the COVID-19 pandemic has been associated with an increased risk of mental health problems across many subpopulations including pregnant and postnatal women. This study examined the prevalence and correlates of depressive symptoms (depression hereafter) in Chinese pregnant and postpartum women during the COVID-19 pandemic. METHODS This was a multicenter, cross-sectional study comprising 1309 pregnant and postpartum women across 12 provinces in China during the COVID-19 pandemic. Depression was assessed using the nine-item Patient Health Questionnaire. Univariate analyses and multivariate logistic regression analyses were conducted. RESULTS The prevalence of depression in pregnant and postpartum women was 27.43% (95% confidence interval [CI] = 25.01%-29.85%). Women who were worried about themselves or their babies being infected with COVID-19 (odds ratio [OR] = 2.562, 95% CI = 1.670-3.929), and those who had delayed regular medical checkups (OR = 2.434, 95% CI = 1.580-3.750) were at higher risk of depression. Compared with those living in central and western parts of China, women living in northern (OR = 0.513, 95% CI = 0.326-0.807) and southeastern parts of China (OR = 0.626, 95% CI = 0.463-0.846) were less likely to have depression. CONCLUSIONS The COVID-19 pandemic was associated with an increased likelihood of mental health problems among pregnant and postnatal women. Over a quarter of the pregnant and postpartum women in China had depression during the COVID-19 pandemic. Considering the negative health impact of depression, preventive measures, regular mental health screening, and medical checkups are needed with the goal to reduce the risk of depression in this vulnerable population during a pandemic.

Abstract
OBJECTIVE To investigate the expression and possible role of hypoxia-inducible factor-1 (HIF-1) at the maternal-fetal interface following Toxoplasma gondii infection during early pregnancy. METHODS Twenty pregnant C57BL/6 mice, each weighing 16 to 20 g, were randomly divided into 4 groups, including the 12-d control group, 12-d infection group, 18-d control group and 18-d infection group. Mice in the 12-d and 18-d infection groups were injected intraperitoneally with 150 tachyzoites of the T. gondii PRU strain on day 6 of pregnancy, while mice in the 12-d control and 18-d control groups were injected with the same volume of phosphate buffered saline (PBS). Mice in the control and infection groups were sacrificed on days 12 and 18 of pregnancy, and the placental and uterine specimens of the pregnant mice in each group were sampled for pathological examinations. The mRNA expression of HIF-1α, HIF-1β and vascular endothelial growth factor (VEGF) was quantified using quantitative fluorescent real-time PCR (qPCR) assay in the placental and uterine specimens, and the correlation between HIF-1α and VEGF mRNA expression was examined. In addition, and the HIF-1α expression was detected using immunohistochemical staining in the placental and uterine specimens of pregnant mice. RESULTS Compared with the 12-d and 18-d control groups, adverse pregnant outcomes were observed in mice in 12-d and 18-d infection groups, such as teratism and placental dysplasia. HE staining showed swelling and blood stasis of cells, sinusoid reduction and inflammatory cell infiltration in the labyrinth area of the placenta specimens of mice in 12-d and 18-d infection groups relative to 12-d and 18-d control groups, and columnar epithelial cell injury and inflammatory cell infiltration were seen in the mouse uterine specimens in both infection groups. qPCR assay detected significantly higher HIF-1α (F = 132.6, P < 0.05) and HIF-1β mRNA expression (F = 286.9, P < 0.05) in the placental specimens and lower HIF-1α (F = 111.5, P < 0.05) and HIF-1β mRNA expression (F = 55.2, P < 0.05) in the uterine specimens in the 12-d infection group than in the 12-day control group, and significantly lower HIF-1α and HIF-1β mRNA expression was detected in the placental and uterine specimens in the 18-d infection group than in the 18-day control group (F = 215.8, 418.9, 156.8 and 200.1; all P values < 0.05). Significantly lower VEGF-A (F = 426.2, P < 0.05), VEGF-B (F = 104.6, P < 0.05) and VEGF-C mRNA expression (F = 566.9, P < 0.05) in the placental specimens and higher VEGF-A (F = 426.2, P < 0.05), VEGF-B (F = 104.6, P < 0.05) and VEGF-C mRNA expression (F = 566.9, P < 0.05) in the uterine specimens were detected in the 12-d infection group than in the 12-d control group, and higher VEGF-A, VEGF-B and VEGF-C mRNA expression was found in the placental and uterine specimens in the 18-d infection group than in the 18-d control group (F = 521.9, 100.6, 275.9, 224.6, 108.2 and 333.4; all P values < 0.05). Immunohistochemical staining showed strongly and mildly positive HIF-1α expression in the mouse placental labyrinth area in the 12-d and 18-d infection groups relative to 12-d and 18-d control groups, while no HIF-1α expression was detected in mouse uterine specimens. CONCLUSIONS HIF-1α expression appears a tendency towards a rise in the second trimester and a reduction in the third trimester in mice following T. gondii infection during early pregnancy, which is contrary to the changing tendency of VEGF-A, VEGF-B, and VEGF-C expression. It is hypothesized that HIF-1α inhibits placental angiogenesis in mice during pregnancy through suppressing VEGF expression, resulting in adverse pregnant outcomes.

Abstract
Neural precursor cells-expressed developmentally down-regulated protein-8 (NEDD8) is one of the important members of the ubiquitin family, which plays an important role in maintaining cell stability, cell cycle regulation, signal transduction, transcription, and translation, DNA repair, and tumorigenesis through covalently bound substrates (also known as neddylation modification). In recent years, studies have found that the dysfunction of NEDD8 and its related enzymes is common in liver diseases, and is widely involved in the biological processes of hepatitis, liver fibrosis, proliferation, invasion, apoptosis and autophagy of liver cancer cells. This article focuses on the research progress of NEDD8 in liver diseases.

Abstract
BACKGROUND In December 2019, coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in Wuhan, Hubei, China. Moreover, it has become a global pandemic. This is of great value in describing the clinical symptoms of COVID-19 patients in detail and looking for markers which are significant to predict the prognosis of COVID-19 patients. METHODS In this multicenter, retrospective study, 476 patients with COVID-19 were enrolled from a consecutive series. After screening, a total of 395 patients were included in this study. All-cause death was the primary endpoint. All patients were followed up from admission till discharge or death. RESULTS The main symptoms observed in the study included fever on admission, cough, fatigue, and shortness of breath. The most common comorbidities were hypertension and diabetes mellitus. Patients with lower CD4+T cell level were older and more often male compared to those with higher CD4+T cell level. Reduced CD8+T cell level was an indicator of the severity of COVID-19. Both decreased CD4+T [HR:13.659; 95%CI: 3.235-57.671] and CD8+T [HR: 10.883; 95%CI: 3.277-36.145] cell levels were associated with in-hospital death in COVID-19 patients, but only the decrease of CD4+T cell level was an independent predictor of in-hospital death in COVID-19 patients. CONCLUSIONS Reductions in lymphocytes and lymphocyte subsets were common in COVID-19 patients, especially in severe cases of COVID-19. It was the CD8+T cell level, not the CD4+T cell level, that reflected the severity of the patient's disease. Only reduced CD4+T cell level was independently associated with increased in-hospital death in COVID-19 patients. TRIAL REGISTRATION Prognostic Factors of Patients With COVID-19, NCT04292964 .

Abstract
Feed efficiency is a highly important economic trait in sheep production and has a significant impact on the economic benefits of sheep farming. Microbial fermentation of the rumen has a vital role in the host's nutrition; the rumen microbiota might affect host feed efficiency. However, the relationship between the rumen microbiota and feed efficiency in sheep is unclear. In the present study, the microbiota of 195 Hu sheep was investigated and their residual feed intake (RFI), a commonly used measure of feed efficiency, was determined. From birth, all sheep were subjected to the same management practices. At slaughter, samples of liquid rumen contents were collected and subjected to amplicon sequencing for the 16S rDNA gene on the IonS5™XL platform. To identify the bacterial taxa differentially represented at the genus or higher taxonomy levels, we used linear discriminant analysis coupled with effect size and curve fitting. In the sheep rumen, the four most abundant phyla were Firmicutes, Bacteroidetes, Fibrobacteres, and Proteobacteria; and the dominant genera were unidentified Prevotellaceae, Fibrobacter, unidentified Lachnospiraceae, Saccharofermentans, and Succinivibrio. Pathway analysis of the 16S rDNA sequencing data from the rumen microbiota identified that carbohydrate metabolism was enriched. Using α-diversity analysis, we further identified that Observed species, ACE, Good's coverage, and Chao1 are more abundant (P < 0.01) in the low-RFI (L-RFI) group compared to the high-RFI (H-RFI) group. High-RFI sheep had a higher abundance of three bacterial taxa (Prevotellaceae, Negativicutes, and Selenomonadales), and one taxa was overrepresented in the L-RFI sheep (Succinivibrio), respectively. Furthermore, model fitting showed that Veillonellaceae, Sphaerochaeta, Negativibacillus, Saccharofermentans, and members of the Tenericutes, Kiritimatiellaeota, Deltaproteobacteria, and Campylobacterales were correlated with the sheep RFI classification and thus were indicative of a role in animal efficiency. Tax4Fun analysis revealed that metabolic pathways such as "energy metabolism," "metabolism of cofactors and vitamins," "poorly characterized," and "replication recombination and repair proteins" were enriched in the rumen from H-RFI sheep, and "genetic information processing" and "lipopolysaccharide biosynthesis" were overrepresented in L-RFI sheep rumen. In addition, six Kyoto Encyclopedia of Genes and Genomes orthology pathways were identified as different between H-RFI and L-RFI groups. In conclusion, the low RFI phenotype (efficient animals) consistently (or characteristically) exhibited a more abundant and diverse microbiome in sheep.

Abstract
Background: This study examined the prevalence of depressive symptoms (depression hereafter) and its association with quality of life (QOL) among pregnant and postnatal women in China. Methods: In this multi-center, cross-sectional study, 1,060 pregnant and postnatal women from eight hospitals were assessed. Depression and QOL were measured using the Edinburgh Postnatal Depression Scale and the World Health Organization Quality of Life Questionnaire - brief version, respectively. Results: The prevalence of depression was 7.45% (95% CI: 5.87-9.04%) in the sample. Women with depression had lower QOL in physical, psychological, social and environmental domains compared to those without. Women with physical comorbidities were more likely to suffer from depression (OR = 2.391, 95% CI = 1.384-4.130, P = 0.002). Conclusion: Due to its negative association with QOL, increased attention should be paid to depression in pregnant and postnatal women. Regular screening assessment and preventive measures should be adopted to reduce risk of depression in this population.

Abstract
Long noncoding RNAs (LncRNAs), as key regulators, have vital functions in various biological activities. However, in sheep, little has been reported concerning the genetic mechanism of LncRNA regulation of feed efficiency. In the present study, we explored the genome-wide expression of LncRNAs and transcripts of uncertain coding potential (TUCPs) in the livers of sheep with extreme residual feed intake (RFI) using RNA sequencing. We identified 1 523 TUCPs and 1 996 LncRNAs, among which 10 LncRNAs and 16 TUCPs were identified as being differentially expressed between the High-RFI and Low-RFI groups. Co-expression and co-localization methods were used to search for LncRNA and TUCP target genes, which identified 970/1 538 and 23/27 genes, respectively. Ontology and pathways analysis revealed that the LncRNAs/TUCPs that were highly expressed in the Low-RFI group are mostly concentrated in energy metabolism pathways. For example, LNC_000890 and TUCP_000582 might regulate liver tissue metabolic efficiency. The LncRNAs/TUCPs that were highly expressed in the High-RFI group are mostly enriched in immune function pathways. For example, TUCP_000832 might regulate animal health, thereby affecting feed efficiency. Subsequently, a co-expression network was established by applying the expression information of both the differentially expressed LncRNAs and TUCPs and their target mRNAs. The network indicated that differentially expressed genes targeted by the upregulated LncRNAs and TUCPs were mainly related to energy metabolism, while those genes targeted by the downregulated LncRNAs and TUCPs were mainly related to immune response. These results provide the basis for further study of LncRNA/TUCP-mediated regulation of feed efficiency.

Abstract
Background Eosinophil levels predict prognosis in ST‐segment elevation myocardial infarction (STEMI) patients. Both eosinophils and high‐sensitivity C‐reactive protein (hs‐CRP) play a major role in the acute inflammatory response of myocardial infarction. The purpose of this study was to evaluate eosinophil percentage (EOS%) and hs‐CRP as prognostic markers for in‐hospital adverse events in STEMI patients undergoing primary percutaneous coronary intervention. Methods We retrospectively analyzed the clinical data of 518 patients. Major adverse cardiac events (MACEs) were defined as cardiac rupture, cardiac arrest, malignant arrhythmia, and cardiac death. Based on the receiver operating characteristic (ROC) analysis, all patients were regrouped into 3 groups (None, One, and Two) according to cutoff EOS% value (≤0.3%) and hs‐CRP value (>11.8 mg/L). Both Cox regression analyses and the KM (Kaplan‐Meier) survival curve were used to examine the prognostic role of combined hs‐CRP and EOS% in cardiovascular events. Results Of the 518 STEMI patients, 50 of them developed MACEs. Patients who developed MACEs had a significantly lower EOS% and higher hs‐CRP than patients who remained MACE‐free. In the multivariable Cox regression analysis, the highest risk of in‐hospital MACEs was constantly observed in patients with a combined low EOS% and elevated hs‐CRP. Patients with reduced EOS% and high hs‐CRP had significantly higher incidence rates of cardiac rupture (P = .001), cardiac arrest (P = .001), and malignant arrhythmia (P < .001); furthermore, they had the worst cumulative survival compared with the other two groups. Conclusion Combined reduced EOS% and elevated hs‐CRP were valuable tools for identifying patients at risk of in‐hospital MACEs.

Abstract
Tissue nonspecific alkaline phosphatase (TNAP) is expressed widely in different tissues, modulating functions of metabolism and inflammation. However, the effect of TNAP on cardiac fibrosis remains controversial and needs to be further studied. The present study aims to investigate the role of TNAP on myocardial infarction (MI)-induced fibrosis and its mechanism. TNAP was upregulated in patients with MI, both in serum and injured hearts, and predicted in-hospital mortality. TNAP was also significantly upregulated after MI in rats, mostly in the border zone of the infarcted hearts combined with collagen synthesis. Administration of TNAP inhibitor, tetramisole, markedly improved cardiac function and fibrosis after MI. In the primary cultures of neonatal rat cardiac fibroblasts (CFs), TNAP inhibition significantly attenuated migration, differentiation, and expression of collagen-related genes. The TGF-β1/Smads signaling suppression, and p-AMPK and p53 upregulation were involved in the process. When p53 inhibitor was administered, the antifibrotic effect of TNAP inhibition can be blocked. This study provides a direct evidence that inhibition of TNAP might be a novel regulator in cardiac fibrosis and exert an antifibrotic effect mainly through AMPK-TGF-β1/Smads and p53 signals.

Abstract
Objective: To assess the prevalence and influence factors of cataract at different altitudes in Gansu Province. Methods: A total of 7 560 permanent residents aged 50 years and over in seven regions of Gansu Province (altitude, 900 meters to 3 500 meters) were selected as subjects, including 2 402 males and 5 158 females, with an average age of 62.04 years. The cluster random sampling method was used to conduct the survey at village or township health service centers. The investigation procedure included questionnaire survey, pre-investigation, visual acuity examination, intraocular pressure measurement, slit lamp microscopy and fundus examination. The diagnostic criterion for cataract was typical opacity of the lens or no other eye diseases that led to visual impairment but with visual acuity less than 0.7. The prevalence of cataract was calculated according to factors such as altitude, age and sex. The Chi-square test and two-element unconditional logistic regression were used for statistical analyses. Results: A total of 7 560 people were surveyed. The prevalence rate of cataract was 39.7%, and the age-standardized prevalence was 37.7%. The prevalence of cataract increased with age (χ(2)=2 107.19, P<0.01). It was 14.1% in the group of 50-59 years, 42.9% in the group of 60-69 years and 79.2% in the group of over 70 years. The prevalence of cataract also increased with altitude (χ(2)=33.66, P<0.01). It was 36.9% in the group of altitude less than 1 000 meters, 39.0% in the group of altitude between 1 000 meters and 1 999 meters, 45.9% in the group of altitude between 2 000 meters and 2 999 meters, and 51.5% in the group of altitude more than 3 000 meters. With age stratification, the prevalence of cataract at high altitude was higher than that at low altitude (χ(2)=26.74, 16.06, P<0.01). Multivariate regression analysis showed that the risk of cataract was higher in subjects at altitude of 2 000-2 999 meters than those below 1 000 meters (OR=1.42, 95%CI 1.11-1.82), and even higher in those at altitude of 3 000 meters (OR=1.76, 95%CI 1.01-3.06). Conclusions: High altitude and old age are important risk factors for cataract, and high altitude is an independent risk factor for cataract. It is necessary for local health institutions to take measures to reduce the prevalence of blindness and low vision, especially the blindness caused by cataract.

Abstract
Mussel adhesive proteins (MAPs) have a unique ability to firmly adhere to different surfaces in aqueous environments via the special amino acid, 3,4-dihydroxyphenylalanine (DOPA). The catechol groups in DOPA are a key group for adhesive proteins, which is highly informative for the biomedical domain. By simulating MAPs, medical products can be developed for tissue adhesion, drug delivery, and wound healing. Hydrogel is a common formulation that is highly adaptable to numerous medical applications. Based on a discussion of the adhesion mechanism of MAPs, this paper reviews the formation and adhesion mechanism of catechol-functionalized hydrogels, types of hydrogels and main factors affecting adhesion, and medical applications of hydrogels, and future the development of catechol-functionalized hydrogels.

Abstract
BACKGROUND Receptor-interacting serine-threonine kinase 3 (RIPK3)-mediated necroptosis has been implicated in the progression of myocardial infarction (MI), but the underlying mechanisms, particularly whether microRNAs (miRNAs) are involved, remain largely unknown. RESULTS A microarray analysis was used to screen for miR-325-3p expression in myocardial tissues from MI mice, and the expression was confirmed with qRT-PCR. The levels of myocardial enzymes were measured using commercial kits, and an echocardiography system was utilized for the detection of cardiac function parameters. The pathological features and infarction sizes of cardiac tissues were examined using H&E, TCC and Masson's trichrome staining, and the amount of cell apoptosis was determined using an in situ TUNEL assay. Cardiomyocytes were isolated and then subjected to hypoxia induction in vitro. The expression of the RIPK1, RIPK3 and phosphorylated MLKL (p-MLKL) proteins was measured using a Western blot. The mouse cardiomyocyte cell viability was analyzed by an MTT assay. The mRNA target of miR-325-3p was predicted using TargetScan v7.2 and then validated using a dual-luciferase reporter assay. The overexpression of miR-325-3p evidently decreased the expression levels of lactate dehydrogenase (LDH), phosphocreatine kinase (CK), superoxide dismutase (SOD) and malondialdehyde (MDA), inhibited left ventricular end-diastolic diameter (LVEDD) and left ventricular end-systolic diameter (LVESD), and promoted left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVES). In addition, miR-325-3p overexpression attenuated the degree of injury to the cardiac tissue, decreased the infarct sizes and downregulated the expression of the necrosis-related proteins RIPK1, RIPK3 and p-MLKL. CONCLUSIONS The RIPK1/RIPK3/p-MLKL axis-induced necroptosis that occurred during MI was mediated by a miRNA module, miR-325-3p, which can effectively ameliorate the symptoms of MI by suppressing the expression of RIPK3.

Abstract
Objective: To compare the safety and efficacy between proximal gastrectomy and total gastrectomy and to ascertain the optimized procedure for patients with upper third gastric cancer through meta-analysis. Methods: The English literatures about proximal gastrectomy and total gastrectomy for upper third gastric cancer were searched from PubMed, EMBASE, the Cochrane Library and the Web of Science database and then collected. The quality of enrolled studies was independently assessed by two researchers according to the Newcastle-Ottawa Scale for retrospective studies and Jadad scale for RCT studies. The basic information of the literature and related clinical indicators were extracted. The primary endpoints were 5-year overall survival rate and recurrence rate. The secondary endpoints were operative time, intraoperative blood loss, morbidity of postoperative complication, incidence of anastomotic stenosis and incidence of reflux esophagitis. Considering the influence of tumor staging on postoperative clinicopathological features and prognosis, a subgroup analysis was performed on the literatures including cases of early gastric cancer and those including cases of tumor stage I to IV. Statistical analyses were carried out by the "metafor" and "meta" software packages from RevMan 5.3 software and R software (V3.2.4). Results: Twenty-five literatures involving 3667 patients (proximal gastrectomy for 1483, total gastrectomy for 2184) were finally enrolled for analysis, including 24 retrospective studies with ≥ 5 points and 1 RCT with 3 points, and all the literatures were of high quality. A total of 2516 cases of early gastric cancer were enrolled in 18 articles, including 1027 with proximal gastrectomy and 1489 with total gastrectomy. A total of 1151 cases with stage I to IV were enrolled in 7 articles, including 456 in proximal gastrectomy group and 695 in total gastrectomy group. Five-year survival rate was not significantly different for patients with early gastric cancer between the proximal gastrectomy group and total gastrectomy group (OR=1.16, 95% CI: 0.72 to 1.86, P=0.54). Similarly, there was no significant difference for patients with stage I to IV between the proximal gastrectomy group and the total gastrectomy group (OR=1.19, 95% CI: 0.92 to 1.53, P=0.18). Recurrence rate of early gastric cancer patients was not significantly different between the proximal gastrectomy group and the total gastrectomy group (OR=0.40, 95% CI: 0.05 to 3.16, P=0.39).However, the recurrence rate of the proximal gastrectomy group was higher than that of the total gastrectomy group in patients with stage I to IV (OR=1.55, 95% CI: 1.09 to 2.19, P<0.01), whose difference was statistically significant. There was no significant differences in postoperative complication between the groups, both in patients with early gastric cancer, and in those with stage I to IV (both P>0.05). The incidences of postoperative anastomotic stenosis (OR=3.57, 95% CI: 1.82 to 6.99, P<0.01) and reflux esophagitis (OR=2.83, 95% CI: 1.23 to 6.54, P=0.01) in the proximal gastrectomy group were significantly higher than those in the total gastrectomy group in patients with early gastric cancer. Conclusions: There is no significant difference in long-term survival outcomes between total gastrectomy and proximal gastrectomy for upper gastric tumors. However,incidence of anastomotic stenosis and reflux esophagitis, and tumor recurrence rate after total gastrectomy are significantly lower. The total gastrectomy is recommended as the first choice for advanced upper gastric tumor.

Abstract
Objective: To investigate the effects of preoperative percutaneous transhepatic biliary drainage on surgical treatment of type Ⅲ and Ⅳ hilar cholangiocarcinoma. Methods: Clinical data of 72 patients with hilar cholangiocarcinoma of the Bismuth-Corlette type Ⅲ and Ⅳ treated at Department of General Surgery,First Affiliated Hospital of Bengbu Medical College from January 2010 to December 2017 were analyzed retrospectively.Patients were divided into two groups based on whether PTBD was performed:a drained group and an undrained group.In the drained group,there were 31 patients,20 males and 11 females,aged (59.9±9.7)years (range: 39-73 years).Among them,14 patients underwent hepatectomy with half or more than half of the liver removed (extended hepatectomy)and 17 patients underwent non-anatomical hepatectomy in the hilar region (limited hepatectomy).In the undrained group,there were 41 patients, 26 males and 15 females, aged (60.8±7.8)years(range: 45-75 years).Among them, 17 patients underwent hepatectomy with half or more than half of the liver removed (extended hepatectomy)and 24 patients underwent non-anatomical hepatectomy in the hilar region (limited hepatectomy).Percutaneous transhepatic biliary drainage(PTBD)was used in the drained group.Under the guidance of ultrasound,one or more hepatobiliary ducts could be sufficiently drained,which had good effect and was not restricted by the obstruction location of hilar cholangiocarcinoma.The analysis of the measurement data was performed using t test,and the analysis of the count data was performed using χ(2) test,and the survival curve was plotted using Kaplan-meier method. Results: In total, 72 jaundiced patients with hilar cholangiocarcinoma underwent surgical treatment: 31 had PTBD prior to operation while 41 did not had PTBD.There were significant differences in ALT((93.2±21.4)U/L vs.(207.4±65.1)U/L),AST((87.6±18.1)U/L vs.(188.9±56.6)U/L)and total bilirubin((68.8±12.6)μmol/L vs.(227.5±87.7)μmol/L)between the patients after treatment and those before treatment(t=10.958, P=0.000; t=10.845, P=0.000; t=10.386, P=0.000).Compared with those in the undrained group, the operation time was shorter, the amount of intraoperative bleeding and the incidence of complications were lower in the drained group(t=-2.840, P=0.006; t=-3.698, P=0.000; χ(2)=4.108, P=0.043).There were no perioperative death cases in drained group and 2 perioperative death cases in undrained group.There was no significant difference in R0 resection rate between the two groups(χ(2)=0.778,P=0.378).The 1-,3-,5-year survival rate of patients in the drained group and the undrained group was 72.7%,34.2%, 13.7% and 72.8%, 31.5%, 11.8%, respectively.The difference was not statistically significant(all P>0.05). Conclusions: The preoperative percutaneous transhepatic biliary drainage in patients with hilar cholangiocarcinoma of Bismuth-Corlette type Ⅲ and Ⅳ could effectively shorten operative time, reduce amount of intraoperative bleeding and incidence of postoperative complications,but have no significant effect on the R0 resection rate and survival rate.

Abstract
Objective: To evaluate the clinical effects of ultrasound-guided subacromial injection of two drugs in treatment of subacromial impingement syndrome. Methods: This was a randomized controlled trial study, prospective collection of patients' data who were diagnosed as subacromial impingement syndrome at Orthopedic of Tianjin Fifth Central Hospital from January 2015 to August 2017. To ensure the randomness of the study, patients were randomized into two groups using a random number table. Pain(visual analogue scale(VAS)) and shoulder function (University of California Shoulder Score System(UCLA) and shoulder abduction) were performed before and after each injection.For continuous endings with multiple points in time, firstly, the normality, the homogeneity of variance, and the sphericity test of Mauchly were performed. After the condition was satisfied, the variance analysis of the two-factor repeated measurement data was performed. Results: Fifty-two patients completed the injection within 5 minutes and 41 patients got the final follow-up. Twenty-two patients in the corticosteroid group, 14 males and 8 females, aged (44.7±9.5) years old(range: 35-68 years old). The lesion involved 13 cases of superior shoulder, more than 1 time injection in 4 cases. There were 19 patients in the NSAID group, 7 males and 12 females, aged (37.2±10.1) years old(range: 27-63 years old), 10 cases with lesions involving superior shoulders, and 1 case with more than one injection. (1)VAS score: compared with pre-injection(Corticosteroid group 5.0(4.0-6.0)and NSAIDS group 5.0(4.0-6.0)), both groups showed significant pain relief at 60 minutes(1.0(1.0-2.0)and 1.0(1.0-2.0)) and 6 weeks(1.5(1.0-2.0)and 1.0(1.0-2.0)) after injection(χ2=47.293, 41.173, 45.174, 40.113; P<0.01). (2)UCLA score: compared with pre-injection(30.2±2.5 and 30.5±3.0), UCLA scores improved significantly in both groups at the 6-week after injection(Corticosteroid group: MD=9.727, t=19.218, P<0.001; NSAID Group: MD=9.579, t=11.467, P<0.01). The UCLA score improvement between the two groups was no statistical difference(all P>0.05). (3)shoulder abduction degree: compared with pre-injection(92.7±9.4 and 93.2±11.6), the abduction degree was significantly improved in both groups at 60 minutes(131.8±9.6 and 127.4±16.6) and 6 weeks(115.9±9. 1 and 127.9±14.4) after the injection, but the improvement in each time point has no statistical correlation(MD=4.450, t=1.069, P=0.292). NSAID group had better improvement of shoulder abduction degree than corticosteroid group at the 6 weeks after the injection(MD=-11.986, t=-3.238, P=0.002). Conclusions: Ultrasound-guided subacromial injection can reduce pain in patients with subacromial impingement syndrome.The effect of injection of NSAID drugs is the same as corticosteroid drugs, it can avoid hormone-induced complications and reduce the repeat of the punctures.

Abstract
Effective hemostasis is vital to reduce the pain and mortality of patients, and the research and development of hemostatic materials are prerequisite for effective hemostasis. Chitosan (CS), with good biodegradability, biocompatibility and non-toxicity, has been widely applied in bio-medicine, the chemical industry, the food industry and cosmetics. The excellent hemostatic properties of CS have been extensively studied. As a result, chitosan-based composite hemostatic materials have been emerging. In this review, the hemostatic mechanism of chitosan is briefly discussed, and then the progress of research on chitosan-based composite hemostatic materials with multiple forms such as films, sponges, hydrogels, particles and fibers are introduced. Finally, future perspectives of chitosan-based composite hemostatic materials are given. The objective of this review is to provide a reference for further research and development of effective hemostatic materials.

Abstract
Objective: To explore the correlation between the severity of gastroesophageal reflux cough and degree of gastroesophageal reflux. Methods: A cross-sectional investigation was carried out. Data of 174 cases of chronic cough were collected in Children's Hospital of Fuzhou from March 2009 to December 2016. The esophageal 24 hours pH value dynamic monitoring was used to detect gastric acid reflux index. Cases with abnomal results were divided into mild, moderate and severe groups according to severity of reflux and that of day and night cough symptoms, respectively. They were also divided into infant (1-3 years old), preschool (4-6 years old), and school age (>7 years old) groups according to age. Comparative analysis between groups by chi-square test and rank sum test were performed. Correlation analysis was used to analyze the correlation between cough severity and gastroesophageal reflux index. Results: A total of 174 patients with chronic cough, including 115 males and 59 females, aged from 1 to 15 years with an average age of (8.5±2.3) years, and (1.6±0.8) years of disease duration were enrolled. Among them, 129 cases (74.1%) were positive for esophageal reflux test and 45 cases (25.9%) with no obvious pathological gastroesophageal reflux. Patients with positive esophageal reflux test were divided into severe (n=37, 28.7%), moderate (n=23, 17.8%), and mild (n=69, 53.5%). There was no significant difference in the distribution of gastroesophageal reflux in each age group. (The proportions of mild, moderate and severe reflux in infants were 45.0% (9/20), 25.0% (5/20), and 30.0% (6/20), respectively. The proportions of mild, moderate and severe reflux in preschool children were 53.3% (32/60), 16.7% (10/60), 30.0% (18/60), respectively. The proportions of mild, moderate and severe reflux in school age children were 57.1% (28/49), 16.3% (8/49), 26.5% (13/49), respectively χ(2)=1.204, P=0.877). There was no correlation between age group and gastroesophageal reflux (r=-0.065, P=0.489).The severity of nighttime cough was positively correlated with percentages of distal esophagus pH≤4 in time, recumbent pH≤4 in time, and DeMeester score<14.72 (r=0.689, 0.621, and 0.707 respectively, all P<0.05). There was no statistically significant correlation between the severity of nighttime cough symptoms and percentage of standing pH≤4 in time (r=0.113, P>0.05). There were no statistically significant correlation between the severity of daytime cough and all gastroesophageal reflux markers (all P>0.05). Conclusion: The severity of nocturnal symptoms of gastroesophageal reflux cough is related to the degree of gastroesophageal reflux, to which clinical pediatricians should pay attention.

Abstract
Objective: To investigate the effect of AKT1 deSUMOylation induced by Ubc9 silencing on the proliferation and metastasis of hepatocellular carcinoma (HCC) cells. Methods: The Ubc9 gene was silenced using RNA interference, and the expression levels of Ubc9, SUMO1 and AKT1 protein were detected by Western blot. Cell proliferation and cell cycle was analyzed by MTT and flow cytometry. Wound healing and transwell assays were used to detect the cell migration ability. Furthermore, the xenograft model was established, and tumor growth curves were drawn. The in situ apoptotic rates was measured using TUNEL Apoptosis Assay. The expression of proliferating cell nuclear antigen (PCNA), matrix metalloproteinase (MMP)-2 and MMP-9 were evaluated by immunohistochemical staining. Results: Knockdown of Ubc9 gene significantly decreased the protein expression levels of Ubc9, conjugated SUMO1, free SUMO1 and AKT1 in HCC cells (P<0.05 for all). In control, siR-neg and siR-Ubc9 groups, the cell proliferation indexes were 53.19%, 54.25% and 39.17%, respectively. Moreover, cell migration distance and migrating cells per low power field for all these three groups were (59.47±4.66) μm and 89.44±8.36, (56.56±5.37) μm and 93.84±8.79, as well as (34.57±6.61) μm and 41.67±5.39, respectively. In the xenograft model, the weights of subcutaneous tumors for these three groups were (3.78±0.69) g, (3.72±0.72) g and (2.09±0.61) g, respectively. The corresponding apoptotic cell rates were (7.79±2.21)%, (6.45±2.48)% and (33.59±5.44)%, respectively. The expression levels of PCNA, MMP-2 and MMP-9 protein were significantly decreased in siR-Ubc9 group (P<0.05). Conclusions: Ubc9 silencing in HCC cells induces AKT1 deSUMOylation, and then inhibits the proliferation and metastasis. These results provide a new therapeutic strategy for liver cancer in the future.

Abstract
The rarity of primary small cell carcinoma of the esophagus (PSCE) has limited the clinical feature and survival analysis with large sample size. Tissue chromogranin A (CgA) protein expression has been reported to be a useful biomarker for diagnosing PSCE. Interestingly, recent studies have indicated tissue CgA as a significant prognostic marker in multiple human cancers, but without PSCE. The present study, thus, was undertaken to characterize the clinicopathological changes and to evaluate the associations of tissue CgA expression with clinical response on Chinese PSCE patients. All the 125 PSCE patients were enrolled from our 500,000 esophageal and gastric cardia carcinoma databases (1973-2015), constructed by the cooperative team from more than 700 hospitals in China and established by Henan Key Laboratory for Esophageal Cancer Research in Henan, China. Immunostaining for CgA showed that CgA was mainly located in cytoplasm of tumor cells with a positive detection rate of 44.6%. The CgA positive expression rate in PSCE at lower segment of the esophagus (72.2%) was higher than that at middle segment (41.5%) (P = 0.001). However, CgA protein expression did not correlated with lymph node metastasis (P = 0.767), TNM staging (P = 0.740), tumor invasion (P = 0.253), gender (P = 0.262), and age (P = 0.250). Multivariate survival analysis showed that the patients with higher CgA protein expression had a superior long survival than those without CgA expression (P = 0.037). The clinicopathological analysis showed that PSCE occurred predominantly in male (M:F = 1.9:1) at the middle segment (68%) of the esophagus. Histologically, 89.6% were pure PSCE and 10.4% were mixed type with either squamous cell carcinoma (8%) or adenocarcinoma (2.4%). It was noteworthy that, with the in-depth invasion from T1 to T2 and T3, the positive lymph node metastasis rate increased dramatically from 38%, 56% to 74%, respectively. The survival rates of 1-, 2-, 3-, and 5-year were 64%, 35%, 18%, and 7%, respectively. The Kaplan-Meier survival analysis showed that the young patients (≤60 years) had longer survival than the elderly (P = 0.011). Interestingly, multivariate survival analysis revealed that the patients with mixed PSCE had a significantly better survival than those with pure PSCE (P = 0.015). Furthermore, the median survival time for the patients with and without lymph node metastasis was 1.16 and 2.03 years, respectively. But, the difference was not significant (P = 0.143). Univariate analysis did not show any survival influence by gender, tumor location, tumor invasion depth, and TNM staging. It was noteworthy that, of the 13 early PSCE patients (T1N0M0), only one patient had more than 5 year survival, the others died with less than one or two year (65%). The present study indicates that the PSCE is of badly worsen prognosis, even in the pathological early stage. Tissue CgA protein expression is a promising maker not only for diagnosis and also for prognosis. Further assessment is needed to establish specific PSCE pathological staging system and to clarify the mechanisms of CgA protein in PSCE progression and prognosis.

Abstract
The present study compared the prognostic value of a marker, the C-terminal section of the arginine vasopressin prohormone (copeptin), with N-terminal B-type natriuretic peptide (NT-proBNP) in patients with severe acute decompensated heart failure. A prospective, observational cohort study was conducted in a tertiary care hospital and enrolled 129 patients with severe acute decompensated heart failure. Clinicians were blinded to investigational markers except NT-proBNP, and the study participants were followed up for 90 days. The end-point was a composite of cardiovascular death or re-hospitalization due to decompensated heart failure. Of the 129 patients enrolled, 47 reached the end-point and 82 were in a stable condition during follow-up. Receiver operating characteristic curve analysis revealed that the areas under curve for the prediction of adverse events within 90 days were similar for copeptin [0.602±0.052; 95% confidence interval (CI), 0.499-0.705], NT-proBNP (0.659±0.048; 95% CI, 0.565-0.753) and their combination (0.670±0.050; 95% CI, 0.573-0.767). Kaplan-Meier survival analysis showed that the predictive value of NT-proBNP regarding the probability of survival was superior compared with that of copeptin (log-rank test for trend, P=0.001 vs. 0.040). Furthermore, multivariate Cox proportional-hazards regression analysis revealed that increased NT-proBNP and copeptin plasma concentrations were significant independent predictors of adverse events. The present study provided evidence that copeptin has similar predictive properties compared with NT-proBNP regarding adverse events within 90-days in patients with severe acute decompensated heart failure, but that copeptin may not provide superior 90-day prediction compared to NT-proBNP.

Abstract
OBJECTIVE To explore response element that maintains basic transcriptional activity of intestinal trefoil factor (ITF) promoter. METHODS Truncated and mutant 5' flanking sequences of ITF gene were cloned from ITF promoter sequences by PCR, and then they were inserted into the pGL3-basic vector to construct truncated and mutant luciferase vectors to conduct the following experiments. (1) Human embryonic kidney 293 (HEK293) cells were divided into pGL3-basic group, pGL3-300 group, pGL3-280 group, pGL3-260 group, pGL3-240 group, pGL3-220 group, and pGL3-200 group according to the random number table (the same grouping method below), with 3 wells in each group, and they were respectively transfected with 500 ng corresponding plasmids and 15 ng renilla luciferase reporter plasmids pRL-TK. After being cultured for 48 hours, the relative luciferase activity of cells was measured by single tube detection system. (2) Another batch of HEK293 cells were divided into pGL3-basic group, pGL3-300 group, mutant 1, 2, 3, and 4 groups, with 3 wells in each group, and they were respectively transfected with 500 ng pGL3-basic, pGL3-300, mutant 1, 2, 3, and 4 plasmids and 15 ng pRL-TK plasmids. After being cultured for 48 hours, the relative luciferase activity of cells was measured as in (1). (3) Another batch of HEK293 cells were divided into blank control group and 10, 50 μmol/L mithramycin groups, with 3 wells in each group. After being transfected with 500 ng pGL3-300 plasmids and 15 ng pRL-TK plasmids, cells in blank control group were not transfected with mithramycin, while cells in the latter two groups were respectively transfected with 10 and 50 μmol/L mithramycin. After being cultured for 24 hours, the relative luciferase activity of cells was measured as in (1). (4) Another batch of HEK293 cells were divided into blank control group and 0.1, 0.2, and 0.3 μg pcDNA3.1-Sp1 groups, with 3 wells in each group. After being transfected with 500 ng pGL3-300 plasmids and 15 ng pRL-TK plasmids, cells in blank control group were not transfected with pcDNA3.1-Sp1 plasmids, while cells in the latter three groups were respectively transfected with 0.1, 0.2, and 0.3 μg pcDNA3.1-Sp1 plasmids. After being cultured for 48 hours, the relative luciferase activity of cells was measured as in (1). Data were processed with one-way analysis of variance and LSD test. RESULTS (1) The relative luciferase activity of cells in pGL3-basic group, pGL3-300 group, pGL3-280 group, pGL3-260 group, pGL3-240 group, pGL3-220 group, and pGL3-200 group was 1.00, 7.99±0.51, 2.03±0.55, 2.50±0.40, 2.50±0.15, 1.72±0.19 and 2.10±0.21, respectively. The relative luciferase activity of cells in pGL3-280 group, pGL3-260 group, pGL3-240 group, pGL3-220 group, and pGL3-200 group was significantly lower than that in pGL3-300 group (with P values below 0.01). (2) The relative luciferase activity of cells in pGL3-basic group, pGL3-300 group, mutant 1, 2, 3, and 4 groups was 1.00, 7.99±0.51, 2.10±0.56, 7.03±1.05, 5.09±1.40 and 8.15±1.48, respectively. The relative luciferase activity of cells in mutant 1 group was significantly lower than that in pGL3-300 group (P<0.01). The relative luciferase activity of cells in pGL3-300 group, mutant 2, 3, and 4 groups was similar (with P values above 0.05). (3) The relative luciferase activity of cells in 10 and 50 μmol/L mithramycin groups was respectively 3.07±0.60 and 2.93±0.55, which was significantly lower than that in blank control group (8.05±0.83, with P values below 0.01). (4) The relative luciferase activity of cells in 0.1, 0.2, and 0.3 μg pcDNA3.1-Sp1 groups was respectively 12.74±1.12, 14.52±1.25, and 15.66±1.82, which was significantly higher than that in blank control group (8.13±0.71, with P values below 0.05). CONCLUSIONS One Sp1 binding site, locating in the region from -301 to -293 bp of ITF promoter, is the core element for regulating the basic transcriptional activity of ITF.

Abstract
BACKGROUND/AIMS Myocardial ischemia/reperfusion injury is a major cause of morbidity and mortality associated with coronary heart disease. Many studies have demonstrated that natural products are promising chemotherapeutic drugs counteracting the loss of cardiomyocytes. Thus, the purpose of the present study was to investigate the effects of geniposide, a traditional Chinese herb extract from Gardenia jasminoides J. Ellis, on cardiomyocyte apoptosis induced by hypoxia/reoxygenation (H/R) in H9c2 cells, and their underlying mechanisms. METHODS Cell viability and apoptosis ratio were assessed using the cell counting kit-8 assay and Annexin V/propidium iodide (PI) staining. The concentrations of lactate dehydrogenase (LDH), intracellular total superoxide dismutase (T-SOD), and malondialdehyde (MDA) were detected by microplate reader. The production of reactive oxygen species/reactive nitrogen species (ROS/RNS), the level of mitochondrial calcium, and mitochondrial membrane potential depolarization were measured by confocal laser scanning microscopy. Mitochondrial morphology was visualized using transmission electron microscopy. The expressions of Bcl-2 mRNA and Caspase-3 mRNA were measured by reverse transcription-polymerase chain reaction (RT-PCR). The protein levels of cleaved caspase-3, Bcl-2, Bax, AKT, p-AKTserine473, cytochrome-c were detected by western bloting. RESULTS Geniposide pretreatment increased cell viability, decreased LDH levels in the supernatant, and inhibited cardiomyocyte apoptosis caused by H/R. Furthermore, geniposide reversed mitochondrial dysfunction by decreasing oxidative stress products (ROS/RNS and MDA), increasing anti-oxidative enzyme (T-SOD) level, improving mitochondrial morphology, attenuating mitochondrial calcium overload and blunting depolarization of mitochondrial membrane. Moreover, geniposide pretreatment increased Bcl-2 level and decreased Bax level, thus enhancing the Bcl-2/Bax ratio. Consistent with the above result, Bcl-2 mRNA expression was upregulated and caspase-3 mRNA expression was downregulated by geniposide. In addition, geniposide decreased the protein expression of cleaved caspase-3 and cytochrome-c and increased the level p-AKTserine473. The protective effects of geniposide were partially reversed by glucagon-like pepitide-1 receptor antagonist exendin-(9-39) and the phosphatidylinositol 3 kinase (PI3K) inhibitor LY294002. CONCLUSIONS Our results suggest that geniposide pretreatment inhibits H/R-induced myocardial apoptosis by reversing mitochondrial dysfunction, an effect in part due to activation of GLP-1R and PI3K/AKT signaling pathway.

Abstract
This study investigated the frequency of aspiration pneumonia in conscious stroke patients fed by a family member and examined the effect of introducing training in swallowing techniques by nurses. A total of 96 consecutive patients presenting with dysphagia due to acute stroke were included in the study. Patients presenting between January 2000 and July 2003 ( n = 48) were fed orally by a family member given general nursing information (group A), whereas those presenting between August 2003 and March 2005 ( n = 48) were fed orally by an experienced nurse trained in specific swallowing techniques (group B). All patients were examined daily for the presence of aspiration pneumonia. The incidence of aspiration pneumonia was 33.3% in group A and 6.3% in group B ( P < 0.05). The incidence of aspiration pneumonia in dysphagic stroke patients who are orally fed is still high. Training in swallowing during oral feeding offers clear protection against pneumonia in conscious stroke patients.

Abstract
Target leaf spot is a sorghum leaf disease caused by Bipolaris sorghicola, a species of fungus with a global distribution. In this study, we investigated the process by which B. sorghicola invades cells of barley, onion, Arabidopsis thaliana species, and sorghum. The results showed that within 8 h of coming into contact with host cells, the hyphal ends of B. sorghicola expand and form a uniform infective penetration pegbolt-like structure; a primary infection mycelium can be formed inside host cells within 24 h after contact, which can infect closed cells after 48 h. A mycelium can grow within the gap between cells and form infective hyphae. The pathogen infection process was the same in different host cells. B. sorghicola can affect root cells through soil infection, indicating that it may also have characteristics of soil-borne pathogens.
