Objective: To describe the prevalence of alcohol consumption and the burden of hemorrhagic stroke and hypertensive heart disease attributed to alcohol consumption in adults aged ≥20 years in 31 provinces in China from 2005 to 2018. Methods: Data from several national representative surveys was used to estimate provincial alcohol exposure level of adults aged ≥20 years from 2005 to 2018 by using kriging interpolation and locally weighted regression methods. Global disease burden research method and data, and China's death cause surveillance data were used to calculate the population attributable fraction (PAF) of hemorrhagic stroke and hypertensive heart disease and the deaths due to alcohol consumption in men and women aged ≥20 years in 31 provinces in China. China census data of 2010 were used to calculate the attributable standardized mortality rate. Results: In 2005 and 2018, the prevalence of alcohol consumption was 58.7% (95%CI: 57.8%-59.5%) and 58.4% (95%CI: 57.6%-59.3%), respectively, in men and 17.0% (95%CI: 16.6%-17.4%) and 18.7% (95%CI:18.1%-19.3%), respectively, in women. The daily alcohol intake was 24.6 (95%CI: 23.8-25.3) g and 27.7 (95%CI: 26.8-28.7) g, respectively, in men and 6.3 (95%CI: 6.0-6.5) g and 5.3 (95%CI: 5.0-5.6) g, respectively, in women. Alcohol exposure level was higher in the provinces in central and eastern China than in western provinces. The lowest exposure level was found in northwestern provinces. From 2005 to 2018, the PAF of hemorrhagic stroke death due to alcohol consumption increased from 5.5% to 6.8%, the attributable deaths increased from 50 200 to 59 100, while the PAF of hypertensive heart disease death due to alcohol consumption increased from 7.0% to 7.7%, the attributable deaths increased from 15 200 to 29 300. The PAF of hypertensive heart disease and hemorrhagic stroke was higher in men than in women, and in central and eastern provinces than in western provinces. In 2018, the standardized mortality rates of hemorrhagic stroke and hypertensive heart disease attributed to alcohol consumption were 4.58/100 000 and 2.11/100 000, respectively. Conclusions: The prevalence of alcohol consumption in men and daily alcohol intake of drinkers were relatively high in China, especially in eastern provinces. Alcohol exposure level was lower in women than in men. Regional measures should be taken to reduce the alcohol intakes in men and current drinkers in order to reduce the health problems caused by alcohol consumption.

This study aims to investigate the regulatory effect of Sishen Pills(SSP) and its split prescriptions Ershen Pills(EP) and Wuweizi Powder(WP) on T follicular helper(Tfh) cell subset in the dextran sodium sulfate(DSS)-induced colitis mice and the mechanism. A total of 60 male SPF BALB/c mice were used, 10 of which were randomly selected as the normal group. The rest 50 were induced with 3% DSS solution for colitis modeling. After modeling, they were randomized into 5 groups: model group, SSP group, EP group, WP group, and mesalazine group. Body mass, colon mass, colon mass index, colon length, and unit colon mass index in each group were observed. After hematoxylin-eosin(HE) staining, the pathological injury of colon tissue was scored. The expression levels of molecules related to the STAT/SOCS signaling pathway in colon tissues were analyzed by Western blot. Differentiation levels of Tfh cells such as CD4~+CXCR5~+IL-9~+(Tfh9), CD4~+CXCR5~+IL-17~+(Tfh17), and CD4~+CXCR5~+Foxp3~+(Tfr) in peripheral blood of mice were detected by flow cytometry. The results showed each treatment group demonstrated significant increase in body mass and colon length, decrease in colon mass, colon mass index, unit colon mass index, and histopathological score(P<0.05, P<0.01), reduction of the expression of p-STAT3, STAT3, p-STAT6, and STAT6(P<0.05, P<0.01), rise of the expression of SOCS1 and SOCS3(P<0.05, P<0.01), decrease of Tfh9 and Tfh17 cells, and increase of Tfr cells(P<0.05, P<0.01) compared with the model group. These results indicated that SSP and the split EP and WP may alleviate ulcerative colitis by inhibiting the activation of STAT/SOCS signaling pathway and regulating the balance of Tfr/Tfh9/Tfh17 cells.

This study evaluated the regulatory effect of curcumin on memory follicular T cells (mTf) in obese mice with ulcerative colitis on the basis of determining its effective treatment of ulcerative colitis in obese mice. Forty male leptin mutant (ob/ob) mice were randomly divided into control group, control + curcumin group, dextran sodium sulfate (DSS) group and DSS + curcumin group, with 10 mice in each group. Mice in the DSS group and the DSS + curcumin group were induced by DSS to establish chronic ulcerative colitis model, and mice in the control + curcumin group and the DSS + curcumin group were given curcumin (200 mg·kg^-1·d^-1) by intragastric administration. Mice were sacrificed under anesthesia, and colon mass index, colon length and other conditions were observed in each group. Pathological injury of colonic was performed after HE staining. The levels of memory follicular helper T cells (mTfh) and memory follicular regulatory T cells (mTfr) in spleen of mice were detected by flow cytometry. The expression levels of interleukin-10 (IL-10) and interleukin-17A (IL-17A) in colon tissue were detected by ELISA. The results showed that curcumin significantly increased the body weight and colon length of obese mice with colitis, and decreased the colon weight, colon mass index and pathological score (P < 0.05). Curcumin significantly reduced the levels of central memory follicular T cells (cmTf), mTfh1, mTfh17 cells and the content of pro-inflammatory cytokine IL-17A (P < 0.01). The levels of effector memory follicular T cells (emTf) and mTfr and the content of anti-inflammatory cytokine IL-10 were increased (P < 0.05, P < 0.01). Therefore, curcumin may treat colitis in obese mice by regulating the balance of mTf cell subsets.

As the most advanced environment-friendly production model in the international society, ecological agriculture of Chinese materia medica(CMM) is the only way for the development of modern agriculture. With the proposal of the declaration on ecolo-gical agriculture of CMM, "Don't grab land from farmland, don't be enemies of grass and insects, don't be afraid of barren slopes and forests, and live up to the green and green mountains", the ecological planting of CMM has blossomed all over the country, and formed a scientific theory, technology and model. Based on the theory and method of economics, this paper expounds the comprehensive benefits and development advantages of ecological agriculture of CMM from the perspectives of farmers(producers), patients(consumers) and the country. From the perspective of medicinal farmers, the input and output income of conventional agriculture and ecological agriculture of CMM such as Panax ginseng, Astragalus propinquus, Atractylodes lancea, and Bupleurum chinense were compared, and it was found that ecological agriculture of CMM had obvious advantages in net income, average annual income and input-output ratio, which could better promote farmers' income. From the perspective of patients, according to the same dose, the content of active ingredients in ecologically planted CMMs is significantly higher than that in conventionally-planted herbs, and the amount of effective substances taken by patients is also higher, so as to achieve better therapeutic effect. At the national level, ecological planting of CMM is the key to ensuring the high-quality development of CMM industry, increasing farmers' income, ensuring the safety of people's drug use and promoting the sustainable development of agriculture. It is also an important part of realizing the harmonious development of economy, society and environment and promoting ecological civilization. In general, the declaration on ecological agriculture of CMM embo-dies the core characteristics and goals of ecological agriculture, and also points of the path and vision of ecological agriculture of CMM in the future. The declaration will guide production practice, promote the benefit of farmers, and lay the foundation for the sustainable development of CMM industry.

Objective:To observe the relationship of ventilatory efficiency to cardiac function, especially heart rate recovery after exercise for patients with chronic obstructive pulmonary disease (COPD). Methods:From January, 2019 to December, 2020, 190 patients with COPD were recruited for Cardiopulmonary Exercise Testing. The general condition, medical history and medication history, lung function test and parameters of Cardiopulmonary Exercise Testing were recorded. They were divided into normal group and delay group according to whether the heart rate decline more than twelve beats within a minute after Cardiopulmonary Exercise Testing. Results:There were 89 patients (46.84%) in the delay group. Compared with the normal group, the delay group were older (Z = 2.282, P < 0.05), with less ratio of force exiratory volume in the first second in prediction (FEV_1.0%) (Z = 3.626, P < 0.001), maximum power (t = 5.547, P < 0.001), breath reserve (BR) (t = 2.122, P < 0.05) and higher minimum ventilation equivalent of carbon dioxide (VE/VCO_2nadir) (Z = 3.296, P = 0.001). Logistic regression showed that the COPD severity, VE/VCO_2nadir and BR correlated with heart rate recovery. After adjusting for gender, age, body mass index and COPD severity, VE/VCO_2nadir was an independent risk factor for delayed heart rate recovery (OR = 1.203, 95%CI 1.032 to 1.873, P = 0.004), and the best cut-off point was 33.15 (AUC = 0.6387, 95%CI 0.5595 to 0.7178, P = 0.001). Conclusion:The ventilatory inefficiency may increase the risk of abnormal heart rate recovery after exercise in COPD patients.

In recent years, Tripterygii Radix et Rhizoma polyglycosides have been used more and more widely in clinic, mostly in the treatment of rheumatoid arthritis. Besides, it is also used as a basic immunosuppressive drug to treat various kidney diseases, such as nephrotic syndrome. However, there are many adverse reactions in clinic, as well as controversies over its medication regimen, especially its dosage and time. To make rational use of Tripterygii Radix et Rhizoma polyglycosides in clinic and further study, the pharmacological and toxicological research progress of Tripterygii Radix et Rhizoma polyglycosides was reviewed. The author collected pharmacological and toxicological research literatures of Tripterygii Radix et Rhizoma polyglycosides at home and abroad in recent years, finding that Tripterygii Radix et Rhizoma polyglycosides have the pharmacological effects of anti-inflammation, anti-tumor, kidney protection and immunosuppression, and mainly plays a pharmacological role by regulating the expression of cytokines in NF-κB signaling pathway, mTOR signaling pathway and apoptosis-related signaling pathway. And the toxicological effects of Tripterygii Radix et Rhizoma polyglycosides mostly focused on hepatotoxicity, nephrotoxicity and reproductive system toxicity, which are mostly related to oxidative stress response and expression of inflammatory factors. The main components of Tripterygii Radix et Rhizoma polyglycosides are triptolide and celastrol. The pharmacological and toxicological studies of Tripterygii Radix et Rhizoma polyglycosides are in-depth, the results showed that the efficacy and toxicity were dose-dependent and time-dependent, with no toxicity study of Tripterygii Radix et Rhizoma polyglycosides varying with dosage and time in the context of efficacy, indicating dose-effect, time-effect, dose-toxicity, time-toxicity relationships. Relevant mechanisms still need further study.

Objective To investigate the influence of body mass index(BMI) on the prognosis of patients who had received elective PCI.Methods The study population consisted of 2964 consecutive patients with electivePCIs performed between July 2009 and September 2011. The patients were divided into three groups based on their preoperative BMI levels:the normal group( BMI<24.0 kg/m2,n=810); the overweight group( 24.0 kg/m2≤BMI<28.0 kg/m2,n=1454) and the obese group(BMI≥28.0 kg/m2,n=700). We examined the association between baseline BMI levels and postoperative mortality through a mean(571.5±130.8)days of follow up.Results Patients with high BMI had a higher percentage of comorbidities compared with the normal BMI group. The results of multivariate Cox regression analysis revealed that preoperative BMI was inversely associated with mortality after adjustment for other factors (HR 0.896,95％ CI 0.821-0.977,P=0.031). Compared with the obese group, the hazard ratios for risk of mortality in the overweight and the normal groups were 1.908(95％CI 0.689-5.291,P=0.213) and 2.241(95％CI 1.154-4.350,P=0.017).Conclusions For patients undergoing elective PCI, individuals with obesity and overweight had the better prognosis than those with normal BMI.
