Based on vector auto-regression (VAR) model, this paper takes advantage of Granger causality test, variance decomposition and impulse response analysis techniques to carry out a comprehensive study of the factors influencing the price of Chinese herbal, including herbal cultivation costs, acreage, natural disasters, the residents' needs and inflation. The study found that there is Granger causality relationship between inflation and herbal prices, cultivation costs and herbal prices. And in the total variance analysis of Chinese herbal and medicine price index, the largest contribution to it is from its own fluctuations, followed by the cultivation costs and inflation.

Objective:To study the methods of prevention and occurrence of complications in abdominal operation patients with liver cirrhosis.Methods:Analys is the occurrence of postoperative complications and influencing factors in 41 cases in abdominal diseases patients with liver cirrhosis.Results:The incidence rate of postoperative complications was 63.4%(26/41),19 patients with 1 complication,7 patients with 2 or more than 2 complications.Five patients died,Mortality was 12.2%(5/41).Ascites,Child classification,portal hypertension,esophageal varices and intraopera-tive bleeding were influencing factors of occurrence of postoperative complications in abdominal disease patients with liver cirrhos is analyzed using Logistic regression analysis.Conclusion:Positive perioperative management,reducing the intraoperative and postoperative bleeding,Intra-abdominalinfection prevention and ascitic treatment are importent factors in reducing postoperative complications and mortality.

Objective: To explore pathogeny and clinical effect of physiotherapy in young patients with lumbar disc hemiation (LDH). Method: Eighteen young LDH patients at 20-30 years old were administered comprehensive physiotherapy including lumbar traction, pulsed short wave therapy, pulsed magnetotherapy or low frequency modulated medium frequency electrotherapy. Before and after treatment, lumbar function was assessed with JOA scale. Result: Nine patients had specific trauma history; nine patients had sedentary lifestyle; five patients worked lor more than 8h/d in standing position; four patients had body mass index (BMI) 24-28. There was no significant difference in age, BMI and JOA scores between male and female group (P＞0.05). Patients scored significantly higher after treatment (P＜0.05). The remarkable effective rate of physiotherapy was 72.22%. Conclusion: Trauma, sedentary lifestyle, standing for long time, overweight or obesity are primary risk factors of LDH for youth and should be prevented by health education. Physiotherapy is significant efficient for young LDH patients.

Drug therapy is one of the efficient methods for prostate cancer treatment. However, drug resistance greatly hindered the treatment of prostate cancer patients. Herein, the mechanisms of drug resistance in prostate cancer have been exhaustively reviewed, and that can provide an alternative strategy and new targets for anti-prostate cancer therapy.

A century ago the Flexner Report facilitated the process of modern medical education reform.Half a century ago,Problem-based learning initiated the student-centered medical education model.At present training medical students' competency will usher in the third reform in medical education.Over 100 years' development and in the global context of current medical education reform,China's medical education has become an important part of the world medical education.Harbin Medical University conducted an all-around reform through international cooperation and received the accreditation referenced according to global standards in medical education,which is an epitome of the medical education reform in China.

Objective: To study the effect of levothyroxine replacement therapy on improving diffused left ventricular myocardial lesions and cardiac function in patients with hypothyroidism. Methods: Our research included 2 groups: Hypothyroidism group,n=20 newly diagnosed patients and Control group, n=17 normal healthy subjects. Diffused left ventricular myocardial lesions were quantitatively evaluated by non-invasive cardiac MRI T1 mapping technique. Left ventricular myocardial T1 value and left ventricular function before and after levothyroxine replacement therapy were compared; the relationship between T1 value and thyroid function and the relationship between T1 value and the indicators of left ventricular function were analyzed. Results:①Compared with Control group, Hypothyroidism group had increased left ventricular myocardial T1 value, P<0.01, while decreased cardiac index (CI) and left ventricular peak filling rate (PFR), allP<0.05.②In patients with hypothyroidism, left ventricular myocardial T1 value was negatively related to serum FT3 level (r=-0.52,P=0.0006) and PFR (r=-0.43,P=0.0085).③Compared with pre-therapeutic condition, the patients with recovered normal thyroid function showed obviously decreased left ventricular myocardial T1 value and improved CI, PFR. Conclusion: Levothyroxine replacement therapy may improve diffused left ventricular myocardial lesions in patients with hypothyroidism, and therefore improve the cardiac function.

Objective The aim of this study was to determine if isoflavone genistien has protective effects against high glucose-induced cell apoptosis in human aortic endlthelial cells,and investigate the possible mechanism for this protection.Methods Human aortic endothelial cells subjected to normal (5mmol/L) or high glucose (25mmol/L) were treated with genistein at 0,50,100nmol/L.Parallel experiments were performed with 100nM 17b-estradiol,and also in the presence and absence of the pure anti-estrogen ICI-182,780 (100nmol/L).The effects on cell apoptotic DNA fragmentation were determined using cell death ELISA,and the effects on cellular proliferation were determined using tritiated thymidine incorporation assay.Estrogen receptor expression was detected by Taqman quantitative PCR.Results Genistein at 100nmol/L significantly reduced high glucose-induced DNA fragmentation,and reversed cell DNA synthesis inhibition (P＜0.001) after 24 hours' incubation.The effect of genistein was completely blocked by ICI-182,780administration.Estrogen receptor beta,but not alpha was found to be expressed in these cells.Conclusion Isoflavone genistein shows protection against high glucose-induced cell damage through estrogen receptor beta,reducing apoptotic DNA damage and protecting from the inhibition of cell proliferation.
