Using China National Knowledge Infrastructure, Wanfang, and PubMed database, literature search was conducted with the keywords ^“pregnancy^” and ^“monkeypox^”, and 27 related research articles were selected for analysis. Through a comprehensive review of the related literature, we aim to improve our knowledge of this viral disease, better our prevention, treatment and responses to future monkeypox outbreaks in China, so as to better protect the safety of mothers and infants. Maternal monkeypox can be prevented and controlled, if active and effective measures are taken in time. Drawing on the experience and lessons from monkeypox outbreaks at home and abroad, it is suggested that hospitals and public health agencies at all levels should raise awareness, and establish an effective emergency preparedness system for the prevention and control of potential future outbreaks.

Objective:The study aimed to investigate the effects of exercise on the expression of ferroptosis-related proteins and the associated mechanisms in a post-traumatic stress disorder(PTSD)model induced by transient foot shock.Methods:Thirty-five male C57BL/6J mice(8 weeks old)were randomly divided into three groups:Control group,PTSD group,and Exe+PTSD group.PTSD model mice were established by foot-shock and PTSD behaviors were assessed using a fear conditioning box.Iron distribution areas were detected by Fe3+staining.Western Blot analysis were performed to determine the expression level of ferroptosis-related proteins in the mice.Results:Compared to the control group,the freezing time and Fe3+distribution areas in the cortex and hippocampus were significantly increased in the mice with PTSD(P＜0.05).The levels of ferroportin1(FPN1),glutathione peroxidase 4(GPX4),and brain-derived neurotrophic factor(BDNF)proteins were significantly decreased(P＜0.05),while the expression of high mobility group box 1(HMGB1)protein was significantly elevated(P＜0.05).Exercise significantly reduced freezing time and Fe3+accumulation in the cortex and hippocampus(P＜0.05),and it also up-regulated the expression of FPN1,GPX4,and BDNF proteins(P＜0.05),while down-regulating HMGB1 expression compared to the PTSD group(P＜0.05).Conclusion:This study demonstrates that PTSD induces the ferroptosis-related pathway in mice,and exercise can inhibit iron accumulation and reverse the expression of ferroptosis-related proteins induced by PTSD,there-by alleviating PTSD-like behavior in mice.

Objective:To construct an evaluation index system for comprehensive budget management at public hospitals and conduct empirical research for reference in evaluation of comprehensive budget management at public hospitals.Methods:From May to June 2022, based on the Implementation Measures for the Comprehensive Budget Management System of Public Hospitals and its interpretations, literature analysis, and expert interviews, a preliminary evaluation index system was developed for comprehensive budget management of public hospitals. Then the Delphi method was applied for two rounds of expert consultation, with experts invited to evaluate the importance of indexes, while the analytic hierarchy process was used to calculate the weight values of indexes. Based on such a comprehensive budget management evaluation index system, a questionnaire was developed, and tertiary public hospitals were selected based on the principle of convenient sampling. Then a questionnaire survey was conducted from June to October 2022. The questionnaire was filled out by hospital level leaders(chief accountants), finance/audit leaders, and directors of finance/audit/operation management departments from the sample hospitals with professional knowledge and rich operational management experience in budget management. The comprehensive budget management level of the sample hospital was thus evaluated based on the survey results. Results:The comprehensive budget management evaluation index system for public hospitals was composed of 2 first-level indexes, 4 second-level indexes, and 20 third-level ones. The weights for the 2 first-level indexes of target building and management orientation were both 0.500, while the weights for the 4 second-level indexes, namely strategic implementation, comprehensive coverage, performance evaluation, and adaptation matching were all 0.250. Among the third-level indexes, the weights of budget execution, system improvement, system establishment, organizational construction, and revenue and expenditure business ranked top five, with weights of 0.070, 0.069, 0.066, 0.066, and 0.064, respectively. A total of 95 hospitals were selected for questionnaire survey, and the evaluation found 46 of them with a comprehensive budget management level of " excellent" and " good" , 27 with a " moderate" level, and 22 with a " poor" and " very poor" level. Scores of the third-level indexes were between 39-94 points, while the score of 6 third-level indexes were below 60 points, namely interconnection, budget analysis, compatibility and adaptation, system improvement, participation level, and assessment application.Conclusions:The evaluation index system for comprehensive budget management at public hospitals in this study proves rational and practical, serving as a reference for the evaluation of comprehensive budget management at public hospitals and related researches.

Chronic liver diseases, including chronic hepatitis, autoimmune liver disease, alcoholic liver disease, cirrhosis, fatty liver disease, drug-induced liver injury and so on, are common and important disorders in China. A hospital-community-patient-family integration management model for chronic liver diseases has been implemented since 2018 in Shuangshuinian Community Health Service Center collaborated with Sichuan Provincial People′s Hospital. Patients were taken care by general practitioners in the community health center under the guidance of hospital specialists, and with the active participation of patients and their family. This article introduces this integrated management model and the preliminary accomplishment to provide a reference for the management of patients with chronic liver diseases in the community.

OBJECTIVE： To study the effects of aspirin on the growth and autoghagy of human gastric cancer cells SGC-7901 and BGC-823. METHODS： SGC-7901 and BGC-823 cells were selected as research objects， with phosphate buffer （PBS） as negative control treated for 48 h， MTT assay was used to detect the effects of 1， 2， 4， 6， 8， 10 mmol/L aspirin， 5 mmol/L aspirin alone or combined with 2.5 μmol/L chloroquine， 2.5 μmol/L 3-methyladenine （3-MA） on survival rate of gastric cancer cells. Flow cytometry was used to detect the effects of 2 and 5 mmol/L aspirin， 5 mmol/L aspirin alone or combined with 2.5 μmol/L chloroquine and 2.5 μmol/L 3-MA on the apoptosis rate and cell cycle distribution of gastric cancer cells. Hoechst33258 staining was used to observe the effects of 5 mmol/L aspirin on morphology of gastric cancer cell nucleus； Transwell chamber test was adopted to detect the effects of 5 mmol/L aspirin on the migration of gastric cancer cell. Laser confocal scanning microscopy was used to observe the effects of 5 mmol/L aspirin on autophagy formation in gastric cancer cells. Western blot method was used to detect the effects of 2 and 5 mmol/L aspirin on the protein expression of autophagy markers LC3-Ⅱin gastric cancer cells. RESULTS： Compared with negative control group， aspirin could inhibit the survival rates of SGC-7901 and BGC-823 cells in dose-dependent manner， but had no significant effects on apoptosis rate of SGC-7901 and BGC-823 cells； SGC-7901 and BGC-823 cells were blocked in G1 phase. Compared with aspirin alone group， the survival rates of SGC-7901 and BGC-823 were increased significantly after treated with aspirin+chloroquine and aspirin+3-MA， while the distribution rate of SGC-7901 and BGC-823 cells at G1 phase were decreased significantly， with statistical significance （P＜0.05 or P＜0.01）. Compared with negative control group， there were no obvious DNA fragmentation fragments， apoptotic bodies and fragments of dense bright blue， while the number of migration cells were decreased significantly in SGC-7901 and BGC-823 cells after treated with aspirin （P＜0.001）； the number of autophagosome was increased significantly and the protein expression of LC3-Ⅱ was enhanced significantly （P＜0.05）. CONCLUSIONS： Aspirin can significantly inhibit the growth of SGC-7901 and BGC-823 cells， and arrest cell cycle in G1 phase， the mechanism of which may be associated with the activation of autophagy.

The aim of the present study was to examine the effects of suppression of EphB4 and/or mTOR on the biological behaviors of ovarian cancer cells, and the potential regulatory pathways. Antisense EphB4 vectors and shRNA vectors targeting mammalian target of rapamycin (mTOR) were constructed and transfected into A2780 and SKOV3 cells (two ovarian cancer cell lines). The effects of the antisense EphB4 vectors and the shRNA vectors on the proliferation, apoptosis and invasion of ovarian cancer cells were measured, and the expression of EphB4, mTOR and Akt detected. The results showed that transfection with mTOR shRNA could inhibit growth, induce apoptosis, and reduce invasive ability of ovarian cancer cells, which was accompanied by downregulation of EphB4, mTOR and Akt. The inhibitory effects on cell growth caused by mTOR shRNA alone were weaker than those by antisense pEGFP-C1-EphB4. In the antisense pEGFP-C1-EphB4-transfected cells, it was found that EphB4 knockdown could decrease the mTOR expression and slightly reduce the Akt phosphorylation. Significant suppressive effects on cell growth were observed in cells co-transfected with antisense pEGFP-C1-EphB4 and mTOR shRNA. In co-transfection group, the expression levels of EphB4, mTOR and Akt were distinctly lower than those in other groups. It was concluded that suppression of EphB4 may inhibit the growth of ovarian cancer cells by downregulation of the PI3K/Akt/mTOR pathway, and reverse Akt phosphorylation induced by mTOR shRNA. Inhibition of EphB4 and mTOR combined may cooperatively suppress the biological behaviors of ovarian cancer cells.
