Objective:To investigate the cognitive status of socialist core value among medical students, and to provide reference for the core value education in medical colleges and universities. Methods: 1024 medical students were selected with random cluster sampling method, and the socialist core value was investigated using self-designed questionnaire. Results:It was shown that 69 percent of medical students recognized the importance of socialist core values, but the contents had not been mastered. Social atmosphere, medical student's own short-coming and school education were all the factors leading to the weakness of socialist core values. Conclusion:It is quite necessary to cultivate medical students′socialist core values. Class, school, and society should play the main role to guide the medical students to establish the correct socialist core value.

Objective To investigate whether clinical,endocrine,and sonographic characteristics of infertile women with polycystic ovary syndrome (PCOS) could predict the ovarian response to clomiphene citrate (CC) medication.Methods A prospective study was conducted,85 women with PCOS were given CC 50 mg per day for 5 days.In the case of an absent response,doses were increased to 100 daily in subsequent cycles.Clinical,endocrine,and sonographic characteristics were compared between responders and nonresponders.Results The cycle history (oligomenorrhea or amenorrhea) and antral follicle count (AFC) were significantly different in responders from those in nonresponders (P < 0.05).There were no differences in age,serum testosterone,follicle stimulating hormone (FSH),luteotropic hormone (LH),body mass index (BMI),insulin resistant index (HOMA-IR),and glucose and insulin levels between the two groups (P > 0.05).In addition,multivariate logistic regression analysis indicated that cycle history and AFC were the predictors of ovarian response to CC treatment.Conclusions The cycle history and AFC can be used as the simple and effective parameters to predict ovarian response to CC treatment in PCOS patients.

Objective:To investigate the medical students' cognition of ethical issues in assisted reproductive technology (ART) and discuss the importance of ethical education in medical colleges and universities.Methods:A questionnaire survey about the ethical cognition of assisted reproductive technology was conducted among 632 medical students.The questionnaire included the donation and management of gametes and embryos,and offspring problems.Results:Medical students agreed with most of the current ART-related laws and regulations.however,44.8% of medical students considered that criteria of donating eggs should be relaxed,such as allowing women who do not receive ART treatment be paid for eggs.In addition,a total of 39.0% of medical students supported the legalization of surrogacy technology in china.Conclusion:Medical students exists a certain misunderstanding in egg donation and surrogacy technology.We should give more training to medical students in ethical knowledge.In addition,our country can supplement and perfect the current laws and regulations to a certain extent.

Objective To investigate the expressions of programmed death-ligand 1 (PD-L1) and PD-L2 and phosphorylated protein kinase B (p-AKT) in diffuse large B-cell lymphoma (DLBCL) patients and their correlations with clinicopathological features and prognosis. Methods A total of 68 paraffin-embedded specimens of DLBCL patients diagnosed in Shanxi Provincial Cancer Hospital with detailed follow-up record from January 2010 to December 2012 were included in the study. The expressions of PD-L1, PD-L2 and p-AKT proteins in DLBCL were detected by using immunohistochemistry (IHC). Results The positive rate of PD-L1 protein in DLBCL patients was 22.1% (15/68), which was related to germinal center B-cell (GCB) subtype or not (χ2= 5.591, P= 0.018), clinical stage (χ2= 3.969, P= 0.046), international prognostic index (IPI) grades (χ2=4.178, P=0.041) and treatment remission rate (χ2=6.587, P=0.010). The positive rate of PD-L2 protein in DLBCL patients was 14.7% (10/68), which was related to extranodal metastasis or not (χ2=6.772, P= 0.009). The positive rate of p-AKT for DLBCL patients was 61.8% (42/68), which was correlated with age (≥60 years old) or not (χ2=6.227, P=0.013), Eastern Cooperative Oncology Group (ECOG) grades (χ2=4.005, P=0.045), B symptoms (χ2=10.187, P=0.001) and treatment remission rate (χ2=4.096, P=0.043). Univariate survival analysis showed that the overall survival (OS) rate and progression free survival (PFS) rate of PD-L1 protein positive expression group were lower than those of PD-L1 protein negative expression group (both P< 0.05). In the patients with non-GCB subtype, OS rate and PFS rate of PD-L1 protein positive expression group were lower than those of PD-L1 protein negative expression group (both P<0.05). p-AKT protein positive expression group had poorer OS rate and PFS rate compared to p-AKT negative expression group (both P< 0.05). Correlation analysis showed that PD-L1 protein expression was correlated with PD-L2 and p-AKT proteins expressions (r= 0.380, P= 0.001;r= 0.273, P= 0.025). The prognosis was worse when p-AKT and PD-L1 proteins was co-expressed (P< 0.05). Multivariate analysis suggested high expressions of PD-L1 and p-AKT proteins were independent prognosis risk factors in DLBCL (both P<0.05). Conclusions The expressions of PD-L1 and p-AKT proteins may be involved in the occurrence and development of DLBCL. Blocking PD-1 and PD-L1 access or combined blocking could provide a promising future for the clinical therapy.

Objective:To analyze the data of critical care related literatures published in Web of Science core set by knowledge map visualizing technology, and summarize the research status and hotspots of critical care.Methods:The core set database of Web of Science from January 2011 to December 2020 was searched, the extracted information was standardized and analyzed by knowledge map visualizing technology.Results:A total of 783 articles in the field of critical care were included, and the number of literatures increased year by year, among which the number of articles published in the American Journal of Critical Care(305) was the most. The United States (437) was the country with the most published literatures, and Australia was the country with the highest centrality (centrality=0.67). The number and centrality of articles published from China were at the lower middle level. There was cooperation among countries, but not close cooperation. The cooperation among authors was in the state of small aggregation and large dispersion. Cluster analysis and keyword emergence analysis showed that many aspects in the field of intensive care had been the research hotspots, among which "post intensive care syndrome" and "children′s intensive care" were the research hotspots in recent years.Conclusions:The research field of intensive care is still in the rising stage of development, and post intensive care syndrome and children's intensive care are the latest hotspots in intensive care research.
