[Objective] To investigate the effect of electroacupuncture (EA) of Neiguan (PC6) poinl on rnyocardial fibrosis and myocardial contents of collagen type Ⅰ and type Ⅲ in rats with pressure overload. [ Methods ] Rats were randomized to four groups: pseudo-operation group ( group A), model group ( group B) , EA group ( group C) and western medicine group (group D). Pressure-overloaded rat models were established by restriction of abdominal aortic artery. Left ventricular mass index (LVMI) and blood pressure (BP) in the four groups were observed; the plasma level of angiotensin Ⅱ (Ang Ⅱ ) was detected by radioimmunoassay and myocardial contents of collagen type Ⅰ and type Ⅲ by immunohistochemical staining method. [Results] BP, LVMI, expression levels of Ang If and collagen type Ⅰ and type Ⅲ were increased in group B as compared with those in group A ( P 0.05) . [Conclusion] EA of Neiguan point is effective in preventing and treating myocardial fibrosis induced by pressure overload.

AIM:To analyze and compare the chemical constituents difference between single medicine decoction(SMD) and mixed medicine decoction(MMD) of Changweikang Granules. METHODS: TLC and HPLC methods were applied to comparing the chemical constituents in SMD and MMD of Changweikang. RESULTS: Spots of TLC between SMD and MMD similar,except for some difference in the HPLC. CONCLUSION: The analyses were carried out for the first time.We found that the plus of the chemical constituents in SMD equal to MMD of Changweikang,also during the course of MMD,new constituents may be generated.Based on these,we proposed that the material base of Changweikang were the rational preparation and complementation of the effective components and the generation of new constituents.

Objective To analyze effect of intra-articular injections of sodium hyaluronate combined with diprospan in the treatment of hip osteoarthritis.Methods 90 patients with hip arthritis patients from January 2014 to July 2015 were randomly divided into observation group and control group.45 cases in each group.Control group was given Diprospan treatment, observation group was treated with articular injection of sodium hyaluronate combined with diprospan treatment.After 4 weeks of treatment,patients were followed up and recorded hip pain VAS score and WOMAC score, lipids and C-reactive protein levels, content changes in ESR and TNF-α.Results The patients after hip pain VAS score and WOMAC scores were better than control group(P<0.05).After observation group patients lipids and C-reactive protein were lower than control group(P<0.05).After treatment ESR and TNF-αof observation group were lower than control group’s(P<0.05).Conclusion Intra-articular injections of sodium hyaluronate combined with diprospan in treatment of hip arthritis has definite clinical effect.

Objective To describe the preoperative factors of prolonged intensive care unit length of stay after coronary artery bypass grafting. Methods From 1997 to 2009, 1318 patients underwent isolated CABG in our hospital. Retrospective analysis was performed on these cases. Univariate and multivariate analyses for preoperative risk factors were performed. Prolonged length of ICU stay was defined as initial admission to ICU exceeding 72 h. Results The mean age of patients ( 322women and 996 men) was (67.4±9.4) years. Of 1318 patients undergoing isolated CABG from 1997 to 2009, 205 experienced prolonged length of ICU stay. The length of ICU stay was (40.1 ± 22.5 ) hours and ( 122.6 ± 48.7 ) hours separately.Overall in-hospital mortality was higher among these 205 patients ( 13.7% vs. 1.2%, P ＜0.05 ). The overall mortality was 3.1%. In univariate analyses, there were statistically significant differences with respect to the percentage of CPB, total bypass time, cross-clamp time, number of distal anastomoses, use of pressor agent, use of intro-aortic balloon pump,time of ventilation and hospital mortality. The significant risk factors were age, NYHA class Ⅲ/Ⅳ, left ventricular ejection fraction(LVEF) ＜0.40, renal failure, cerebrovascular and/or peripheral vascular disease, chronic obstructive pulmonary disease, recent acute myocardial infarction, prior percutaneous coronary intervention, left main stenosi, three-vessels disease. The variables entered into the multivariate logistic regression were age, NYHA class Ⅲ/Ⅳ, LVEF ＜0.40, renal failure, chronic obstructive pulmonary disease, recent acute myocardial infarction, prior percutaneous coronary intervention, three-vessels disease. According to the outcome of multivariate logistic regression, we can conclude the model of probability forecast and create a new variable named Pre. The area under ROC curve of the new variable Pre was larger than other variables. Conclusion The main risk factors of prolonged ICU length of stay were LVEF ＜ 0.40, recent acute myocardial infarction, renal failure and chronic obstructive pulmorary disease. The AUC of variable Pre was higher than other' s , which indicated that new variable Pre combining each variable was more valuable than single variable with respect to prediction. A predicted probability of 0. 754 was used as cut-off point for the prognostic test.

Local recurrence and distant metastasis is the major factor of impacting long-term survival for patients with esophageal carcinoma after radical resection. Postoperative radiotherapy and chemotherapy is expected to reduce the rate of local recurrence and distant metastasis, but views for the value of postoperative radiochemotherapy were inconsistent in the past. In recent years, scholars have performed much more clinical studies on postoperative radiotherapy and chemotherapy and found that the combined postoperative radiotherapy and chemotherapy after surgery significantly reduces the recurrence rate and distant metastasis rate and can enhance the survival of the patients.
