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.

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.

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 estimate the longitudinal association between serum lipid biomarkers and the development of cardiometabolic multimorbidity (CMM) in middle-aged and old adults (≥45) in China, while examining effect differences among degree of dyslipidemia aggregation and various dyslipidemia combination patterns.Methods:Based on data from the China Health and Retirement Longitudinal Study (2011-2018), logistic regression analysis was used to evaluate the associations of TC, LDL-C, HDL-C, TG (4 forms of dyslipidemias), degree and pattern of dyslipidemia combination with CMM. We also used restricted cubic splines to show the dose-response associations between 4 lipid biomarkers and CMM development.Results:Of the 6 522 participants included, 590 (9.05%) developed CMM. After adjusting for covariates, all 4 forms of dyslipidemias were positively associated with CMM development (high TC: OR=1.33, 95% CI: 1.03-1.71; high LDL-C: OR=1.35, 95% CI: 1.05-1.75; low HDL-C: OR=1.45, 95% CI: 1.19-1.77; high TG: OR=1.50, 95% CI: 1.20-1.88). The U-shaped dose-response relationship between LDL-C and CMM development was observed ( P for non-linear =0.022). The odds of CMM increased with the increase of dyslipidemias forms, which was highest in those with ≥3 forms of dyslipidemias ( OR=2.02, 95% CI: 1.33-3.06). In various dyslipidemia form combinations, the possibility of CMM development was highest in those with high TC, high LDL-C and low HDL-C ( OR=3.54, 95% CI: 1.40-8.67). High TC and high LDL-C were significantly associated with CMM development in people without cardiometabolic diseases. Low HDL-C was positively associated with diabetes and CMM development in participants without cardiometabolic diseases, cardiovascular disease (CVD) followed by diabetes, and diabetes followed by CVD. High TG was positively associated with diabetes and CMM in participants without cardiometabolic diseases, and diabetes followed by CVD. Conclusions:A total of 4 forms of dyslipidemia were all independently associated with CMM development in middle-aged and old adults in China. The dose-response relationship between LDL-C level and CMM development was U-shaped. The aggregation of 4 forms of dyslipidemia were associated with the development of CMM. Low HDL-C and high TG were significantly associated with multiple patterns of cardiometabolic diseases development.

Objective:To evaluate the efficacy and safety of omalizumab in the treatment of chronic urticaria in children.Methods:A retrospective study was conducted. Patients with chronic urticaria were collected from the Department of Dermatology, Hunan Children′s Hospital from January to December 2021, and divided into a control group and a combination group according to different medication regimens. The patients in the combination group received subcutaneous injections of omalizumab (150 mg, once every 4 weeks) combined with conventional-dosage antihistamines, while the patients in the control group were only treated with double-dosage or multiple types of antihistamines. The course of treatment was 3 to 6 months. The clinical efficacy and adverse reactions were evaluated at 3, 6, and 12 months after the start of treatment, and the recurrence was evaluated at 3 and 6 months after the end of treatment.Results:A total of 46 children with chronic urticaria were collected. There were 23 children (13 males and 10 females) in the combination group, aged from 6 to 17 years and including 16 aged from 6 to 12 years and 7 aged from 13 to 17 years; according to the total serum IgE levels before treatment, the patients in the combination group were divided into an increased IgE subgroup (11 cases) and a normal IgE subgroup (12 cases). In the control group, there were 13 males and 10 females, aged from 6.33 to 16 years and including 15 aged from 6 to 12 years and 8 aged from 13 to 17 years. At 3, 6, and 12 months after the start of treatment, the response rates in the combination group were all 86.96% (20/23), which were all significantly higher than those in the control group (52.17% [12/23], 56.52% [13/23], 56.52% [13/23], P = 0.010, 0.022, 0.022, respectively). In the combination group, the response rates at 3, 6, and 12 months after the start of treatment were all 14/16 in the children aged 6 to 12 years and 6/7 in those aged 13 to 17 years, and there were no significant differences between the two age groups (all χ2 = 0.01, P = 0.907) ; in the control group, the response rates were 5/15, 6/15 and 5/15 respectively in the children aged 6 to 12 years, which were all significantly lower than those in the combination group ( P = 0.002, 0.006, 0.006, respectively). In the combination group, the response rates at 3, 6, and 12 months after the start of treatment were all 9/11 in the increased IgE subgroup and 11/12 in the normal IgE subgroup, and there were no significant differences between the two subgroups (all P = 0.484). During the treatment, no serious adverse reactions were observed in the combination group or control group, and mild somnolence only occurred in 2 children in the control group. At 3 months after the end of treatment, no recurrence was observed in 16 patients in the combination group, 2 out of 6 patients experienced recurrence in the control group, and the recurrence rate was lower in the combination group than in the control group ( P = 0.030) ; at 6 months after the end of treatment, no recurrence was observed in 16 patients in the combination group, 3 out of 6 patients experienced recurrence in the control group, and the recurrence rate was lower in the combination group than in the control group ( P = 0.022) . Conclusion:Omalizumab combined with conventional-dosage antihistamines could improve the clinical efficacy and reduce the recurrence rate in the treatment of chronic urticaria in children, with few adverse reactions.

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.

‍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.
