Objective To explore the effects of health education combined with WeChat′s public platform in the management of risk factors in patients with coronary heart disease. Methods A total of 100 coronary heart disease patients were randomly divided into intervention group and control group and there were 50 cases in each group by the random number table. The intervention group received health education about risk factors combined with WeChat′s public platform for 6 months. The control group received routine health education. Evaluate the control rate of blood pressure, blood glucose and blood lipid and the score of coronary heart disease self-management scale of the two groups before and after the intervention. Results At the 6th month after intervention, the control rate of blood pressure of the intervention group was 88.0％(44/50) and it of the case group was 70.0％(35/50).The difference between the 2 groups was statistically significant (χ2=4.882, P < 0.05). The score of coronary heart disease self-management scale of the intervention group was (102.44±8.22) points and it of the case group was (89.82±8.01) points . The difference between the 2 groups was statistically significant(t=7.776, P < 0.05). Conclusions The health education combined with WeChat′ s public platform contributed to help coronary heart disease patients to establish good self-management behavior and it can be widely used in the management of coronary heart disease risk factors.

Objective To investigate the safe model to prevent and treat complications caused by various artificial liver support system(ALSS).Methods The complications in 191 patients with severe hepatitis during the ALSS(Including plasma exchange、plasma exchange associated with continuous venovenous hemofiltration、plasma exchange associated with hemodiafiltration、plasma exchange associated with plasma absorption、molecular absorbents recycling system) treatment were observed and analyzed. Results During the treatment 287 episodes occurred and the rate of complications was 50.44%(287/569).The clinical manifestation included rash,numbness/tetany,hypotension,blood clotting in the channel,chest distress, disequilibrium syndrome,errhysis on dwell catheter,effusion on dwell catheter.75.61% of these complications was caused by plasma exchange.The rate of complications was the lowest during the treatment of plasma exchange associated with hemodiafiltration.All of these complications got better after prompt sypotomatic therapies were taken.Conclusions Although the rate of complications was high during the treatment of ALSS,all of the complications got better after prompt sypotomatic therapies were taken.This therapeusis must be performed by intensive care.It is more safe than others during the treatment of plasma exchange associated with hemodiafiltration.

Aiming at the weakness of the medical graduate students' ideological and political education,we developed the new mode via investigation and surveying,allowing for the medical characteristics. We suggested that we should bring into full play the tutors and their groups function and excavate the connotation of groups’ morality education on the basis of the scientific research groups to develop the medical students' ideological and political education.

OBJECTIVE:To provide reference for drug production,parchase and use in local governments,health care depart-ment,hospitals,manufacturers and sales enterprises,etc. METHODS:By consumption sum sorting method,the information of 14 categories and key types in 34 hospitals from Chongqing area during 2012-2014 were analyzed statistically such as sales,produc-tion manufacturers. RESULTS:The consumption sum of 34 hospitals from Chongqing area increased by 15%-17% during 2012-2014. The consumption sum and proportion of anti-infective drugs showed a downward trend,decreasing by 3.28%. Those of respi-ratory system drugs and anti-tumor drugs had the largest increase,with increasing rate of 79.01% and 69.39%,respectively. Do-mestic drugs accounted for about 73% market share,and sales of imported drugs increased more than domestic and joint-stock drugs,increasing by 40.17%. Among 6 Chongqing pharmaceutical manufacturers on the top 100 consumption sum shortlist,total consumption sum of 3 manufacturers had increased;the consumption sum of top 10 foreign pharmaceutical manufactures increased year by year. CONCLUSIONS:The consumption sum of drugs is increasing in Chongqing area. Anti-infective drugs accounted for less than 16%,which is the achievements of clinical application of antibiotics special rectification activities for 3 years. Both respi-ratory system disease and malignant tumor have high incidence in Chongqing area. Domestic drugs still are main types in hospital. Foreign manufacturers develop well in China,but Chongqing pharmaceutical manufacturers show unsatisfactory development pros-pect.

Objective To explore the value of echocardiography in the diagnosis of anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) in children.Methods The echocardiographic images of 14 patients with ALCAPA confirmed by operation and 18 patients with endocardial fibroelastosis (EFE) diagnosed by clinical were compared and analyzed.Results Both ALCAPA and EFE exhibited obvious dilated left ventricle,decreased left ventricular systolic function,thick endocardium and mitral regurgitation of different degree.The former additionally showed dilated right coronary artery(RCA) with normal origin,left coronary artery(LCA) emerging from the root or wall of the pulmonary artery(PA),the retrograde flow into PA in LCA and abundant collateral vessels in myocardium.However the later exhibited normal diameter of LCA and RCA and no collateral vessels.Conclusions Color Doppler echocardiography not only demonstrates left ventricular systolic function,endocardium,mitrial regurgitation and collateral vessels in myocardium,but also shows the origination and courses of LCA clearly,which provide exact informations to diagnose ALCAPA.The echocardiography can be used as a powerful tool of ALCAPA diagnosis and preoperative assessment.

Objective To evaluate the safety and efficacy of three types of anesthesia methods in elderly patients with coronary heart disease undergoing unilateral lower extremity surgery.Methods Totally 65 patients with coronary heart disease of cardiac function Ⅰ-Ⅱ (NYHA),scheduled for undergoing unilateral lower limb surgery were randomly divided into three groups:local nerve block anesthesia of lumbar plexus plus the sciatic nerve (21 cases),general anesthesia (19 cases),epidural anesthesia (25 cases).Systolic blood pressure (SBP),heart rate (HR),pulse rate and blood oxygen saturation (SPO2) at 0 min,10 min,20 min,30 min,40 min after surgery at the end of the surgery were observed and recorded.The change of troponin Ⅰ (cTnI) at 3 day after surgery was observed.Visual analoguc scales (VAS) scores.movement reaction,the infortnation of muscle relax and corresponding management were recorded in order to detect anesthesia efficacy.Results The excellent and satisfactory rate of anesthesia efficacy of three groups were 17 cases (81.0％) and 4 cases (19.0％),17 eases (89.5％) and 2 cases (10.5％),22 cases (88.0％) and 3 cases (12.0％) (all P＞0.05).In epiduralgroup compared with other groups,SBP were decreased (both P＜0.05).cTnI in nerve stimulator group was decreased (all P＜0.05) at 1 and 3 day after surgery compared with general anesthesia group,and at 3 day after surgery,cTnI level in nerve stimulator group was lower than other two groups(all P＜0.05).Conclusions The nerve stimulator guided nerve block is the most safe method among general anesthesia and epidural anesthesia in elderly patients with coronary heart disease scheduled for lower extremity surgery.
