OBJECTIVE: To observe the changes of endothelium-dependent dilation (EDD) of patients with congestive heart failure (CHF) before and after Kanli Decoction treatment. METHODS: Thirty-five CHF patients were treated with Kanli Decoction. We used color Doppler ultrasound to monitor the flow-mediated dilation (FMD), pulsatile index (PI), resistance index (RI), baseline blood flow (BF), ejection fraction (EF) before and after the treatment. RESULTS: FMD after treatment (9.26+/-3.19) were obviously higher than that before the treatment (7.06+/-2.58) (P<0.05), but BF, PI and RI were not improved. CONCLUSION: Applying color Doppler ultrasound into observation on EDD of patients suffering from CHF and treated by the Kanli Decoction shows that the CHF could be treated by traditional Chinese medicine.

Objective:To evaluate the effect of remote lifestyle intervention on the management of weight and related indicators in the overweight and obese population.Methods:A total of 400 individuals with overweight or obesity who participated in remote lifestyle intervention in the Health Management Department of Shenzhen People′s Hospital from May 2015 to December 2018 were included as the remote intervention group, and 400 individuals with overweight and obesity who matched their age and gender were selected as the control group. Dietician established individual WeChat groups with the remote intervention group, and the WeChat platform was used to conduct remote lifestyle intervention for them, including setting weight control goals, giving timely feedback to the food log based on photos, providing exercise guidance and psychological support. The control group received personalized diet and exercise prescriptions, but did not receive remote intervention. After adjusting the data by propensity score matching method, univariate and multivariate logistic regression models were used to analyze the management effect of weight and related indicators in the two groups after one year.Results:After one year of intervention, effective data were obtained from a total of 755 cases (371 cases in the remote intervention group and 384 cases in the control group), and effective data were retained from 446 cases (223 cases in the remote intervention group and 223 cases in the control group) after bias matching. The body mass index (BMI), systolic blood pressure, fasting blood glucose, triglyceride, total cholesterol, low-density lipoprotein, and serum uric acid of the remote intervention group [(24.85±2.52) kg/m 2, (110.21±10.53) mmHg, (4.96±0.65) mmol/L, (1.25±0.82) mmol/L, (4.87±1.11) mmol/L, (2.88±0.74) mmol/L, and (306.01±95.66) mmol/L respectively] were significantly lower than that of the control group [(27.76±2.28) kg/m 2, (121.14±14.07) mmHg, (5.10±0.87) mmol/L, (1.54±0.83) mmol/L, (5.28±0.96) mmol/L, (3.13±0.80) mmol/L, (355.16±92.68) mmol/L respectively] (all P<0.05). After intervention, intervention was consistently being influencing factors when BMI was reduced by 4%―12%, ( P<0.05). The probability of a 12% reduction in BMI in the remote intervention group was 112.486 times higher than that in the control group (95% CI: 16.852-890.266). At the same time, the initial BMI was an influential factor for the restoration of normal BMI. For every 1 kg/m 2 decrease in the initial BMI, the probability of restoration of normal BMI was 4.76 times higher than that before the decrease (95% CI: 3.222-5.057). Conclusions:Remote lifestyle intervention has a certain effect on the management of weight and related indicators in the overweight and obese populations. It has significant effect on weight loss of overweight and mildly obese people, but has limited effect on moderate and severe obese people.

OBJECTIVETo study the clinical characteristics of acute myocardial infarction (AMI) among younger adults and to explore the possible mechanisms of early myocardial infarction, combined with the newly discovered risk factors of coronary heart disease.

METHODSData on comparative analysis to the exposure rates of the risk factors and inducing factors of non-CAD patients with two groups of AMI patients including younger adults group (< or =40 years old) and aged adults group (> or =50 years old). Coronary angiography was applied.

RESULTSThere were differences noticed between the frequencies of risk factors of the two AMI groups. In younger adults group the exposure rates of smoking, hyperlipidemia, positive family history, C-reactive protein (CRP) and fibrinogen were markedly higher, while in elderly group the exposure rates of hypertension, smoking, hyperlipidemia, diabetes, CRP, fibrinogen and homocysteine (HCY) were markedly higher (P < 0.05). Although the clustering status of risk factors of the younger adult group was not higher than that of the elderly group. There were obvious inducing factors before the patients were attacked by AMI and the inducing factors inclined to cluster, which had obvious dose-reaction relationships with the occurrence of AMI in young people.

CONCLUSIONEarly AMI of younger adults might relate to the clustering status of inducing factors. The coexistence of several kinds of inducing factors was resulted in the occurrence of AMI of the atherosclerosis (As) and non-As patients by means of myocardial ischemia accumulation effect.
