AIM: A pharmacogostic study of Ipomo pes-caprae (linn.) was carried out. METHODS: Micro-scopic characteristics of the drug were examined and its chemical constituents were monitored by TLC and UV. RESULTS: Marked characteristics were discovered in the crossection of item and leaf. CONCLUSION: The characteristics and the cross sectional structure could provide evidences for the identification of the plant.

Objective:To retrospectively evaluate the clinical effect of mitral valve repair for rheumatic mitral stenosis.Methods:We retropectively analyze the clinical datd of 50 rheumatic mitral disease patients undergoing mitral valve repair from January 2016 to March 2019, the clinical outcome was compaired with those of patients undergoing mitral valve replacement. The operation time, cardiopulmonary bypass time, blood loss, ICU time, hospital stay, and postoperative cardiac function were analyzed, and followed up for 2 years to assess mitral regurgitation, cardiac function, and complication rates.Results:The time of cardiopulmonary bypass and ascending aorta occlusion in the valve repair group were longer than those in the valve replacement group ( P<0.05), and the postoperative ventilator assistance time, ICU stay time, and hospital stay were shorter than those in the valve replacement group ( P<0.05). After 2 years of follow-up, no patients died in the two groups. The rehospitalization rate in the valve repair group was lower than that in the replacement group ( P<0.05), and there was no significant difference in the reoperation rate between the groups ( P>0.05); There was 1 case (2%) of moderate mitral valve regurgitation in the mitral valve repair group, no moderate or severe mitral valve stenosis, no paravalvular leakage in the mitral valve replacement group, and no significant difference between the two groups ( P>0.05). The left ventricular end-diastolic diameter and left ventricular ejection fraction in the mitral valve repair group were significantly better than those in the mitral valve replacement group ( P<0.05). Conclusion:Mitral valve repair is effective in treating rheumatic mitral stenosis. It is beneficial to protect heart function, reduce postoperative anticoagulation complications, and does not increase the rate of reoperation. It is a safe, effective and feasible treatment.

Objective To compare the superiority of total arterial revascularization in patients with coronary artery disease (CAD) complicated with left ventricular dysfunction. Methods This retrospective study included the patients who were diagnosed with CAD and the left ventricular ejection fraction (LVEF) of ≤40% and underwent coronary artery bypass grafting (CABG) at our hospital from January 2016 to July 2019. The patients were divided into two groups according to the different types of bypass vessels: a total arterial revascularization group (TAR group) and a conventional group (a CON group). The clinical data were compared between the two groups to explore the incidence of important complications and evaluate the safety of total arterial revascularization and its protective effect on cardiac function. Results Finally 75 patients were enrolled including 52 males and 23 females with a mean age of (61.58±7.93) years. There were 35 patients in the TAR group and 40 patients in the CON group. The operation time and the drainage volume at 24 hours after operation in the TAR group were longer or more than those in the CON group (P<0.001), but there was no statistical difference in hospital stay, postoperative complications (such as respiratory failure, mediastinal infection, renal failure), intra-aortic balloon pump or extracorporeal membrane oxygenation use rate (P>0.05). After 2 years of follow-up, compared with the CON group, the cardiac function of the TAR group was significantly improved, the LVEF was higher, the left ventricular end diastolic diameter was reduced, and the graft stenosis rate was lower (all P<0.05). Conclusion Total arterial revascularization is a safe and feasible surgical method, which is helpful to improve the cardiac function and improve the quality of life.
