Objective To study the factors affecting hospital death in elderly patients with novel coronavirus infec-tion/disease 2019(COVID-19),and to build a risk prediction model.Methods According to the diagnostic criteria of Diagnosis and Treatment Protocol for COVID-19 Infection(Trial 10th Edition).Totally 775 elderly patients(≥60 years old)diagnosed as COVID-19 infection in the emergency department and fever clinic of the First Hospital of Changsha were selected as the research objects.General data and serum biomarkers of patients were collected.After treatment,the patients'data were divided into survival group and hospital death group.Binary Logistic regres-sion was used to screen the independent influencing factors of death,and ROC curve was used to analyze the pre-dictive value of related indicators on hospital death.Results After treatment,712 patients(91.9%)survived and 63 patients(8.3%)died in hospital.Binary Logistic regression analysis showed that:≥90 years old[OR=5.065,95%CI(1.427,17.974)],type 2 diabetes mellitus[OR= 3.757,95%CI(1.649,8.559)],COPD[OR= 5.625,95%CI(2.357,13.421)],monocyte ratio[OR=0.908,95%CI(0.857,0.963)],plasma fibringen[OR=1.376,95%CI(1.053,1.800)]and lactate dehydrogenase[OR=1.005,95%CI(1.001,o1.008)]were independent factors of in-hospital death(P＜0.05).The predictive value of diabetes mellitus+COPD+age+monocyte ratio+plasma fibrinogen+lactate dehydrogenase was proved in hospital death from COVID-19 infected patients:the area under the curve(AUC)was 0.883(95%CI:0.827,0.940,P＜0.001),the critical value≥0.710 suggested the risk of death in hospital,the specificity was 0.851,the sensitivity was 0.857.Conclusions The hospital mortality of the elderly after COVID-19 infection is higher and closely related to type 2 diabetes,COPD,monocyte ratio,plasma fibrinogen and lactate dehydrogenase.

Objective:To explore the pathogenesis of major depressive disorder(MDD) by comparing the serum glucose and lipid metabolism indicators, levels of glucagon-like peptide-1(GLP-1) in plasma and feces, and the content of specific intestinal flora ( Lactobacillus, Bifidobacterium) between patients with MDD who were diagnosed for the first time and healthy controls. Methods:Totally 80 MDD patients hospitalized from January 1, 2020 to March 30, 2021 and 80 healthy volunteers with normal physical examination in the same period were selected. Blood and fecal samples of patients with MDD and healthy controls were collected respectively. The indicators of serum glucose and lipid metabolism were detected by automatic biochemical analyzer, the concentrations of GLP-1 in plasma and feces were detected by ELISA, and the relative contents of Lactobacillus and Bifidobacterium in feces were detected by real-time PCR. The differences between two groups of glucose and lipid metabolism indicators, GLP-1 levels and the relative contents of Lactobacillus and Bifidobacterium in feces were analyzed. SPSS 22.0 software was used for statistical analysis. Independent sample t-test and analysis of variance were used for inter group comparison, and Pearson correlation analysis was used for correlation analysis. Results:Compared with the control group, the levels of serum TC, HDL, and LDL in the MDD group decreased ((3.99±0.85)mmol/L , (4.78±0.86)mmol/L; (1.18±0.29)mmol/L, (1.30±0.28)mmol/L; (2.64±0.70)mmol/L, (3.19±0.69)mmol/L; t=5.559, 2.371, 4.695, all P<0.05). The plasma and fecal GLP-1 levels of the MDD group were lower than those of the control group (plasma: (0.81±0.22)pmol/mL, (1.05±0.26)pmol/mL , t=4.509, P<0.01; feces: (2.23±0.46)pmol/mL , (2.47±0.37)pmol/mL, t=2.533, P<0.05). Compared with the control group, the relative contents of Lactobacillus(2.56±1.59, 3.51±2.21) and Bifidobacterium(2.24±1.89 , 3.17±2.08) in the MDD group decreased ( t=2.218, 2.082, both P<0.05). The level of plasma GLP-1 in the MDD group was negatively correlated with FPG, TG, and disease severity ( r=-0.281, -0.221, -0.437, P<0.05). The level of plasma GLP-1 in the control group was negatively correlated with FPG ( r=-0.580, P<0.01). The fecal GLP-1 level of the MDD group was negatively correlated with the severity of the disease ( r=-0.298, P<0.01), and the fecal GLP-1 level of the control group was positively correlated with fecal Lactobacillus and Bifidobacterium ( r=0.685, 0.428, P<0.01). Conclusion:MDD patients have abnormal glucose and lipid metabolism, decreased GLP-1 level and decreased relative content of intestinal Lactobacillus and Bifidobacterium. Changes in intestinal flora affect GLP-1 levels. GLP-1 can affect glucose and lipid metabolism and depressive symptoms in patients with MDD by binding to specific receptors in intestinal tract and central nervous system.

In order to understand the status quo of ethical review of clinical research on the defecation function of patients with rectal cancer after sphincter-preserving surgery, analyze its causes and put forward corresponding suggestions, to arouse researchers’ attention to ethical review in subsequent relevant clinical studies. The ethical review of literatures related to the defecation function of patients with rectal cancer after sphincter-preserving surgery published on CNKI in recent 10 years was sorted out and summarized. The results showed that the ethical review of clinical research papers on defecation function of patients with rectal cancer after sphincter-preserving surgery was not optimistic. We should strengthen the ethical training of researchers, improve the ethical awareness of researchers, strictly implement the ethical norms of paper publication, strengthen the ethical requirements of manuscript contracts, perfect the ethical review system, and pay attention to the examination and supervision of informed consent, so as to promote the construction of ethical examination and approval norms of clinical research documents.
