OBJECTIVE: To evaluate the effect of Persian shallot extract on the serum markers and blood pressure of patients with metabolic syndrome(MetS). METHODS: Fifty patients with Met S diagnosis were randomly assigned to the intervention(Persian shallot extract) and the control(placebo) group. Both groups received treatment for three months. Before the study and at the end of the study, 5 mL peripheral blood was taken from each patient. The measured factors included total antioxidant capacity(TAC), superoxide dismutase enzyme(SOD), malondialdehyde, oxidized low-density lipoprotein(Ox-LDL), apolipoprotein H(Apo-H), fasting blood glucose(FBS), total cholesterol, triglycerides, high-density lipoprotein(HDL), LDL, and systolic and diastolic blood pressure. RESULTS: At baseline, the evaluated parameters were not significantly different between the intervention and control groups. At the end of the study, the mean serum levels of malondialdehyde and ox-LDL were significantly lower in the intervention group. The mean FBS, cholesterol, triglycerides, and LDL were significantly lower in the intervention group. The mean TAC and HDL were significantly higher in the intervention group(P < 0.05). Moreover, the intervention group significantly reduced systolic and diastolic blood pressure. No other significant association was observed. CONCLUSION: Persian shallot extract has several beneficial effects in Met S patients, including optimizing oxidative balance, reducing blood pressure, fasting blood sugar, and blood lipid profile.

OBJECTIVE: To screen the target population with symptomatic bradyarrhythmia for pharmacotherapy. METHODS: This study use database from clinical trial that use Yuanjiang decoction(元姜方), a traditional Chinese medicinal prescription. Eligible participants were recruited and treated with Yuanjiang decoction(composed of 6 Chinese herbal medicines), 200 m L twice daily. Cross-contingency analysis, logistic regression analysis, interaction analysis, discriminant analysis and 10-fold cross validation methods were used to establish discriminant model. RESULTS: This study concluded that the clinical treatment of bradyarrhythmia has a clear effect. Low minimum heart rate, high maximum heart rate are risk factors that affect the efficacy. Patients with only one comorbid disease did not significantly affect the efficacy, but patient with two or more diseases of coronary heart disease, hypertension, paroxysmal atrial fibrillation, premature ventricular contraction and premature atrial contraction at the same time did not have a good effect. Using the discriminant analysis method to establish a efficacy prediction model, y = 0.07X1 + 0.16X2-0.65X3-1.12X4-0.71X5-0.75X6-0.91X7(X1 = 24 h mean heart rate, X2 = minimum heart rate, X3 = coronary heart disease, X4 = paroxysmal atrial fibrillation, X5 = premature ventricular contraction, X6= sinus block, X7 = atrioventricular block). CONCLUSION: Our model based on the clinical features of patients with bradyarrhythmia. Should be useful aid for predicting pharmacotherapy response and could screen the optimal pharmacotherapy target.

OBJECTIVE: To enhance the understanding of identifying personalized pharmacotherapy options in Traditional Chinese medicine(TCM), and further support the registration of new TCM drugs. METHODS: Generalized Boosted Models and XGBoost were employed to construct a classification model to identify the bad prognosis factors in resistant hypertension(RH) patients. Furthermore, we used association analysis to explore the rules of "symptomsyndrome" and "symptom-herb" for the major influencing factors, in order to summarize prescription pattern and applicable patients of TCM. RESULTS: Patients with major adverse cardiac events mostly have complex symptoms of phlegm, stasis, deficiency and fire intermingled with each other, and finally summarized the human experience of using Chinese herbal medicine to precisely intervene in some symptoms of RH patients on the basis of conventional Western medical treatment. CONCLUSIONS: Machine learning algorithms can make full use of human use experience and evidence to save clinical trial resources and accelerate the development of TCM varieties.
