Mortality is a key index for assessing technical level and treatment quality of hospital. We filtered and analyzed the literatures about the influence of nurse factors on patient mortality out of China in recent years to guide the study within China. We found the nurse factors impacting mortality included workload, configuration of nursing staff, education status and working environment. Those findings point out the direction of the research on relationship between nurse factors and patient mortality in China, which has great significance.

ObjectiveTo explore the relationship between diet habits and constitution type of 8448adults from 9 provinces and municipalities of China.MethodsA total of 8448 participants from Jiangsu,Anhui,Gansu,Qinghai,Fujian,Beijing,Jilin,Jiangxi and Henan Province were enrolled in this study.The clinical information of constitution type,diet habits and demographic characteristics was collected.Logistic regression analysis was used to evaluate the relationship between diet habits and constitution type.ResultsLogistic regression analysis showed that gentleness type and Qi-deficiency were correlated with sweet food ( OR =1.22,P ＜ 0.05 ). There was a significantly positive correlation between Yangdeficiency and hot food intake ( OR =2.89,P ＜ 0.05 ),as well as between Yin-deficiency and cold food intake ( OR =1.56,P ＜ 0.05).Phlegm-wetness was mainly caused by fatty food consumption ( OR =2.07,P ＜ 0.05 ).Barbecue food was positively correlated with Wet-heat type ( OR =1.64,P ＜ 0.05 ),Bloodstasis type ( OR =1.37,P ＜ 0.05 ),and Qi-depression type ( OR =1.35,P ＜ 0.05 ).Special diathesis type was related to dietary preference of sweet food ( OR =1.29,P ＜ 0.05 ).ConclusionDifferent type of constitution may be related to specific lifestyle or diet habits,and diet habit might play a positive role in Gentleness type or health condition.

Objective To investigate the mechanisms of miRNA-15a and miRNA-16 in the process of reversing cisplatin resistance in ovarian cancer.Methods Human ovarian cancer cisplatin-resistant cell lines CoC1/DDP were transfected with miRNA-15a and miRNA-16 mimics and treated with cisplatin.qRT-PCR was used to detect the expression levels of miRNA-15a and miRNA-16 in normal CoC1/DDP cell group,cisplatin treated group,negative control group,miRNA-15a transfected group,miRNA-16 transfected group and overexpressed Bmi-1 plasmid.Western blot was used to detect the expression level of Bmi-1 in each group,CCK-8 and Annexin V/PI were used to detect cell survival and apoptosis,and γ-H2AX immunofluorescence was used to detect cell apoptosis.Results The CoC1/DDP ovarian cancer cell line shows low expression of miRNA-15a and miRNA-16,and high expression of Bmi-1 protein,which makes it resistant to cisplatin.When the levels of miRNA-15a and miRNA-16 are overexpressed,the Bmi-1 protein decreases(P<0.05),leading to a decrease in cell survival rate(P<0.05),a significant increase in DNA apoptosis(P<0.05),and more severe DNA damage(P<0.05).Overexpression of Bmi-1 plasmid can increase cell viability(P<0.05)and reduce the rate of cell apoptosis(P<0.05).Conclusion The Bmi-1 protein may be a target for the regulation of miRNA-15a and miRNA-16,and overexpression of miRNA-15a and miRNA-16 can increase the sensitivity of ovarian cancer cells to cisplatin by reducing the Bmi-1 protein.This provides a new idea for predicting molecular markers of cisplatin resistance in ovarian cancer and overcoming drug resistance targets in ovarian cancer.

Objective To provide helpful continued medical education (CME) for physicians and improve gout treatment,we conducted a questionnaire survey to investigate physicians' knowledge in nine districts of Beijing.Methods A questionnaire survey including ten gout-related questions was conducted among 298 physicians in Beijing.Demographic data and previous gout CME experience were collected.Chi-square test or Student's t test,univariate analysis and logistic regression analysis were used to evaluate the relevant factors of physicians' knowledge level.Results A total of 250 valid copies were collected including 127 from community service centers (CSC),123 from tertiary hospitals.The correct answer rate of gout etiology,pathogenesis and attack symptoms were over 70％ in both groups.45.5％ (56/123) CSC doctors and 57.4％ (66/115) tertiary doctors answered right drugs to control acute gout attack (P=0.067).Only 42.3％ (52/123) in CSC and 53.4％ (63/118) in hospitals chose allopurinol as a urate-lowering drug (ULT),while 46.3％ (57/123) and 32.2％ (38/118) doctors considered colchicine as a ULT drug (P=0.084) respectively.Near half doctors considered that gout patients should take long-term ULT [40.5％ (51/126) vs.57.6％ (68/118)respectively,P=0.007].Univariate analysis showed that CME training could improve gout-related knowledge in CRC doctors.Conclusion Most CSC doctors generally understand basic knowledge of gout,while confusion of treatment is still significant.CME especially including standard gout treatment should be performed by doctors in tertiary hospitals.

Objective:To observe the main clinical features and outcomes of type 2 diabetes mellitus patients after infection with COVID-19 and to compare them with those without diabetes mellitus.Methods:A single-center retrospective observational study was conducted in 88 in-patients who were diagnosed as COVID-19 from January 1 to February 26, 2020. They were divided into diabetic group and non-diabetic group, with 44 patients in each group. Patients′ medical history, laboratory examination, in-hospital treatment plan, and disease outcome were collected and compared.Results:The clinical symptoms of diabetic patients were varied, mainly fever(75.0%), cough(75.0%), fatigue(52.3%), and so on. The systolic blood pressure(SBP)was higher [131.50(120.00, 140.75) vs 125.00(120.00, 131.75)mmHg, 1 mmHg=0.133 kPa, P=0.021] and the oxygenation was lower [96.00%(94.25%, 97.00%) vs 97.00%(95.00%, 98.00%), P=0.038] at admission compared with the non-diabetic group. Hypertension and chronic kidney disease were more common in diabetic group. Fasting blood glucose [7.64(6.12, 15.43) vs 5.62(5.25, 6.50)mmol/L, P<0.01], interleukin-6(IL-6)[19.85(6.50, 43.38) vs 10.80(3.03, 20.90)pg/ml, P=0.046] in diabetic group were significantly higher than those in non-diabetic group. Secondary infection(27.3% vs 9.1%, P=0.027), ARDS(22.7% vs 4.5%, P=0.013)and shock(4.5% vs 0%, P<0.01)were more likely to occur in the diabetic group. More patients were treated with mechanical ventilation in the diabetic group(20.5% vs 4.5%, P=0.024). The diabetes group was more likely to progress to critical type(20.5% vs 4.5%, P=0.024), and the time to progress to critical state was shorter [3(1.75, 5.25) vs 6(3.00, 12.00)d, P=0.019). The duration of severe symptoms was longer in the diabetic group [26.5(15.00, 31.50) vs 9(8.00, 13.00)d, P=0.026]. Conclusion:The clinical symptoms of type 2 diabetes patients with COVID-19 are diverse. They are often combined with diseases such as hypertension and chronic kidney disease. The inflammatory reaction is more obvious and has more COVID-19 related complications and is more likely to progress into a persistent severe condition in a short time.

With the deepening understanding of the pathogenesis, the definition, staging, diagnosis and treatment of ESLD with AKI have been gradually optimized. This article reviews the evolution of definition, pathogenesis, diagnosis and treatment of ESLD with AKI, to provide reference for early recognition, precise diagnosis and standardized treatment of this condition.

‍Liver failure is a serious clinical syndrome of liver disease with critical condition and high mortality， and besides liver transplantation， there is still a lack of satisfactory radical treatment methods. The pathogenesis of liver failure is complex and remains unclear， involving a variety of factors that affect the balance of hepatocyte necrosis and regeneration. This article summarizes autophagy as the key pathway for maintaining cell homeostasis and points out that autophagy plays an important protective role in the pathogenesis of liver failure by regulating NLRP3 inflammasome activation， reducing oxidative stress， and inhibiting cell apoptosis. Meanwhile， it is believed that the molecular signaling pathways targeting autophagy， such as exosomes and peroxisome proliferator－activated receptor α， participate in antagonizing the development and progression of liver failure and will become important ideas and directions for molecular targeted therapies for liver failure.

OBJECTIVE: To investigate the anti-inflammatory effect and mechanisms of interleukin-35 (IL-35) in inflammatory bowel disease. METHODS: BALB/c mice were divided into three groups with 10 mice in each group:control group, model group (oral administration of 4% glucan sodium sulfate for 7 d) and IL-35-treated group (oral administration of 4% glucan sodium sulfate for 7 d, intraperitoneal injection of 2 μg IL-35 at d2-5). Disease activity index (DAI) was scored every day. After 7 d, the mice were sacrificed, and the serum and intestinal tissue samples were collected. The gross morphology of the colon was observed; HE staining was used to observe the pathological changes of colon tissue; flow cytometry was employed to detect the change of macrophage polarization ratio in colon tissue; the mRNA expression levels of cytokines IL-6, TNF-α, IFN-γ, IL-10 and SHIP1 in colon tissue were determined by real-time quantitative RT-PCR; the expression and distribution of SHIP1 in colon tissue was measured by immunohistochemistry; Western blotting was adopted to detect the expression level of SHIP1 protein in colonic intestinal tissues of each group. RESULTS: The DAI scores of the mice in the model group were higher than those in the control group, while the DAI scores in the IL-35-treated group were lower than those in the model group (all <0.01). Compared with the control group, the colon length was significantly shortened in the model group (<0.05), while the colon length of the IL-35-treated group had an increasing trend compared with the model group, but the difference was not statistically significant (>0.05). Compared with the model group, microscopic inflammatory infiltration score was decreased and microscopic crypt destruction and score was significantly lower in IL-35-treated group (all <0.05). The relative expression of proinflammatory cytokines IL-6, TNF-α and IFN-γ in the colon tissue of IL-35-treated group was decreased compared with the model group, while the relative expression of IL-10 mRNA was higher than that of the model group (all <0.05). Compared with the control group, the proportion of M1 macrophages in the model group increased (<0.05), while the proportion of M1 macrophages in the IL-35-treated group was lower than that in the model group (<0.05). The relative expression of SHIP1 mRNA and protein in the colon tissue of IL-35-treated group was higher than that in the model group (all <0.05). CONCLUSIONS IL-35 can inhibit the polarization of M1 macrophages and regulate inflammatory cytokines to promote anti-inflammatory effect on mice with colitis.

【Objective】 To investigate the expression of Kinesin family member 14 (KIF14), and its correlation with clinical prognosis and immune cell infiltration of clear cell renal cell carcinoma (ccRCC). 【Methods】 The correlation between KIF14 expression in ccRCC and different clinicopathological features were analyzed with TCGA, GEO and Ualcan databases. The correlation between KIF14 expression and prognosis was analzyed with Kaplan-Meier method. The correlation between KIF14 expression and immune cell infiltration was analzyed with TIMER. The protein-protein interaction network of KIF14 was conducted with Genemania. The co-expression genes of KIF14 in TCGA-KIRC were picked out in Linkedomics database and were used to perform GO annotations and KEGG pathway enrichment analysis with R software. The biological functions of KIF14 were verified with in vitro functional assay. 【Results】 KIF14 was highly expressed in ccRCC tissue and was positively correlated with clinical stage, pathological grade, and lymphatic metastasis, but negatively correlated with clinical prognosis. KIF14 expression was an independent risk factor for overall survival of ccRCC patients. GO annotations showed that KIF14 was involved in DNA replication, nuclear division, organelle fission, and cell adhesion. KEGG pathway enrichment analysis showed that KIF14 participated in cell cycle and p53 signaling pathway. Genemania analysis indicated KIF14 interacted with CENPE, CIT, KIF23, and other proteins. Timer showed that KIF14 was positively correlated with immune cell infiltration. Knockdown of KIF14 expression suppressed cell proliferation, migration, and invasion of ccRCC. 【Conclusions】 KIF14 may serve as a novel prognostic marker and a potential therapeutic target of clear cell renal cell carcinoma.
