Objective: Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear. Methods: A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients' medical records. Multivariable logistic regression models were used to estimate the odds ratio ( Results: Overall, 158 (13.6%) patients were diagnosed with severe illness and 32 (2.7%) had unfavorable outcomes. Hypertension (2.87, 1.30-6.32), type 2 diabetes (T2DM) (3.57, 2.32-5.49), cardiovascular disease (CVD) (3.78, 1.81-7.89), fatty liver disease (7.53, 1.96-28.96), hyperlipidemia (2.15, 1.26-3.67), other lung diseases (6.00, 3.01-11.96), and electrolyte imbalance (10.40, 3.00-26.10) were independently linked to increased odds of being severely ill. T2DM (6.07, 2.89-12.75), CVD (8.47, 6.03-11.89), and electrolyte imbalance (19.44, 11.47-32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission (5.46, 3.25-9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes (6.58, 1.46-29.64) within two weeks. Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.

BACKGROUND: Wenyang Yisui Recipe is developed based on Yougui Pills according to many years of clinical practice. The clinical application of Wenyang Yisui Recipe in the treatment of early knee osteoarthritis as a prophylactic and therapeutic treatment has achieved favorable clinical effect. OBJECTIVE: To investigate the clinical efficacy of Wenyang Yisui Recipe combined with arthroscopic osteochondral autografts in the treatment of cartilage lesions of the knee. METHODS: Eighty-three patients under arthroscopic osteochondral autografts for cartilage lesions of the knee were enrolled, including 49 males and 34 females, aged 40 to 67 years old, with an average of (50.2±4.8) years old. The course of disease ranged from 1 to 27 months, with an average of (12.3±5.2) months. According to the Doll’s method, all the patients were divided into study group and control group. The patients in the study group received arthroscopic osteochondral autografts, followed by oral Wenyang Yisui Recipe, 300 mL per day in two divided doses, beginning at 2 days postoperatively for 2 continuous weeks as a session, three sessions in total. The control group only undertook arthroscopic osteochondral autografts. The Lysholm score and visual analogue scale score were used for assessing the knee function and pain, respectively, before surgery and 3 months after surgery. The study protocol was implemented in line with the relevant ethical requirements of Wang Jing Hospital, China Academy of Chinese Medical Sciences in February 2014 (approval No. 221). RESULTS AND CONCLUSION: All patients were followed up for 3 months after surgery. The study group was superior to the control group in the improvement of knee joint pain and swelling score at 3 months after surgery, and the intergroup difference was statistically significant (P < 0.05). The visual analogue scale score was significantly better in the study group than the control group at 3 months after surgery (P < 0.001). The visual analogue scale scores in the two groups were both improved at 3 months after surgery (P < 0.001). Therefore, arthroscopic osteochondral autografts combined with oral Wenyang Yisui Recipe can significantly ameliorate knee pain and function, with definite clinical effects.

Objective: To assess the relationship between body mass index (BMI) and mortality in adults of Shanxi, China. Methods: Baseline data were from the '2002 China Nutrition and Health Survey’ in Shanxi province. All the death-related investigation and follow-up visits were carried out from December 2015 to March 2016. The follow-up program covered 5 360 people from all the 7 007 participants aged 18 years and over that having complete core information, with a rate as 76.5%. Participants of this study were divided into eight groups, according to the appearance of BMI. Taking the group with the lowest mortality density as the reference group, Cox regression model was used to estimate the hazard ratio (HR) and 95% confidence interval (CI) of deaths by the whole population, gender and age groups (≥60 years, <60 years). Results were then adjusted by age, gender, smoking, alcohol use and education level from the baseline survey. Sensitivity analysis was also conducted. Results: Results from the study showed that among the total number of 67 129 person- years from the average period of 12.5 years, there were 615 deaths occurred, with the mortality density as 916 per 100 000 person-years. Taking the BMI range of 26.0-27.9 kg/m² as the reference, the aHRs of death increased to 1.90 (95%CI: 1.26-2.86), 1.68 (95%CI: 1.15-2.45), 1.49 (95%CI: 1.08-2.06) and 1.72 (95%CI: 1.07-2.76) after the multivariate adjustment, in these four groups (BMI<18.5, 18.5-19.9, 22.0-23.9 and ≥30.0 kg/m²), respectively. Low body weight (BMI<18.5 kg/m²) was associated with higher risks of death in the elderly of ≥60 years, with the aHR of death as 1.94 (95%CI: 1.20-3.15). Conclusions When BMI appeared as ≤19.9 kg/m², 22.0-23.9 kg/m² and ≥30.0 kg/m², the risks of death would increase. In addition to programs that focusing on obesity, special attention should be paid to the high risk of mortality which was caused by low-weight and malnutrition in the elderly.

Objective To explore frequency distribution of vitamin D receptor (VDR) genotype and the correlations between polymorphism of VDR gene Bsm Ⅰ sites and bone mineral density in the patients undergoing maintenance peritoneal dialysis.Methods A case-control study was conducted based on 82 patients with maintenance peritoneal dialysis and 80 healthy people.The frequency distribution of VDR genotype in two groups was detected and analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).Serum biochemistry and bone mineral density of the patients undergoing maintenance peritoneal dialysis were detected by dual energy X-ray absorption (DEXA) and automatic biochemical analyzer,respectively.All data was analyzed with SPSS 19.0 software.Results The frequency distribution of VDR genotype between case group and control group had no significant difference (P ＞ 0.05).The serum biochemical index such as Ca,P,alkaline phosphatase (ALP) and parathyroid hormone (PTH)] of patients with maintenance peritoneal dialysis had no significant difference among three VDR genotypes(P ＞0.05).Compared to VDR bb genotype,the serum Ca was significantly higher in VDR BB genotype (P ＜0.05).The bone mineral density (BMD) and T-Score of patients with VDR BB genotype were the lowest,the BB genotype was the highest,and the difference was statistically significant among three genotypes (P ＜0.05).Conclusions The frequency distribution of VDR genotype between case group and control group had no significant difference.However,there is a correlation between VDR gene BsmⅠ sites and bone mineral density of maintenance peritoneal dialysis patients.

Objective To study computer toxicity prediction technology and predict the acute toxicity of Chinese materia medica; To provide a new way and method for safety evaluation of traditional Chinese medicine. Methods First, Mold2 software (version 2.0.0) was used to calculate molecular descriptors of 7409 chemical components. After preliminary screening of molecular descriptors, quantitative structure-activity relationship (QSAR) models were built up with Random Forest (RF) for screening the optimum prediction model. From the 83 kinds of toxic Chinese materia medica in Chinese Pharmacopoeia (2010 edition), acute toxicity of 60 kinds of Chinese materia medica reported from monomer structure (1692 chemical components) were under prediction.Results Totally 7409 pieces of data were obtained. When the descriptors were 52, RF modeling accuracy and Kappa were the highest, 0.712 and 0.436 respectively. Compound clusters were divided into 3 types according to optimum molecule descriptors (52). The accuracy and Kappa of the optimum model for the first type of compounds were 0.666 and 0.476 respectively; the accuracy and Kappa of the optimum model for the second type of compounds were 0.804 and 0.381 respectively; the accuracy and Kappa of the optimum model for the third type of compounds were 0.709 and 0.373 respectively. It was predicted that 60 kinds of Chinese materia medica containing 0 violent toxic compound, 2 high toxic compounds, 172 medium toxic compounds and 1518 low toxic compound.Conclusion QSAR model for prediction study on acute toxicity of chemical components of Chinese mareria medica can provide references combination medication and experimental studies.
