Objective To determine the influence of ginsenoside Rg1 on angiogenesis and the expression of vascular endothelial growth factor (VEGF) and hypoxia inducible factor-1? (HIF-1?) in rat acute myocardium ischemia (AMI) in rat. Methods A murine model of AMI was reproduced. Wistar rats (n=104) were randomly divided into shamoperation group, AMI control group, low ginsenoside Rg1 group (1mg/kg) and high ginsenoside Rg1 group (5mg/kg). Microvascular density, VEGF protein, VEGF and HIF-1? mRNA were assessed at 3, 7, 10 and 14 days after operation. Results The values of VEGF and HIF-1? mRNA were increasing with the duration of ischemia and hypoxia, and positive relationship was found between the time of AMI and the expression of HIF-1? mRNA. Ginsenoside Rg1 enhanced the formation of angiogenesis (P

patients with infective endocarditis were analyzed. Anong them, 75 were patients with congenital heart disease (72 1%), 21 were patients with rheumatic heart disease and 8 were patients without heart disease(7 7%). It is suggested that early diagnoses and treatment of CHD are the main pretective methods for reducing the incidence of IE; the incidence of fever, anaemia, embolism, hepatomegaly and splenomegaly, etc. declines notably; the possibility of excrescence invading aortic valve (44 2%) is higher than that of mitral valve (24 7%), and IE of aortic valve results in heart failure in a short while and the valve replacement should be done as early as possible; positive rate of blood culture declines because of extensive use of antibiotics; appropriate medical treatment combined with active surgical treatment plays an important role in the treatment of IE.

In the process of epithelial-mesenchymal transition (EMT),cell-cell adherence is disrupted,apico-basal polarity is lost,the ability of anti-apoptosis,migration and invasion is acquired.Y-box-binding protein 1 (YB-1) is a member of the cold-shock protein superfamily,containing a structurally and functionally conserved cold shock domain.Studies indicate that YB-1 can promote the occurrence and development of tumors by regulating EMT.In the process of EMT mediated by YB-1,various transcription factors and signal pathways play important roles.

Objective To discuss causes, characteristics and clinical treartment measures for negative fluid balance and systemic edema in patients with traumatic hemorrhagic shock. Methods A retrospective chart study was done on 205 cases with systemic edema posterior to traumatic hemorrhagic shock admitted to ICU between May 1994 and August 2002. Results All cases showed systemic edema at various degrees. The survived 173 cases demonstrated spontaneous diuresis and negative fluid balance at different time in the first week but the died 32 ones not. The negative fluid balance and the spontaneous diuresis were not more severe than that in the control group under conditions of age (≥60 years old), injury severity score (ISS ≥16), acute physiological and chronic health evaluation (APACHE) Ⅱ≥12 and Cr≥2.0 g/L ( P

Objective To evaluate the causes,treatment,and prevention of left ventricular rupture after mitral valvereplacement.Methods From May 1981 to November 2010,11 cases occurred in 4 male and 7 female patients aged 28 - 71 years old.There were 2 cases of New York Heart Association (NYHA) functional class Ⅱ and 9 cases of class Ⅲ.Echocardiography showed that the left ventricular end diastolic internal diameter (LVEDI) was 32 -62 mm.Results Rupture probably occurs after endocardial damage to a thin myocardium that has lost the internal buttress of the subvalvar apparatus.With the rise in intraventricular pressure at the end of bypass blood dissects into the myocardium,resulting in a large haematoma and eventual rupture.According to the onset of ruptures,there were 4 cases of delayed rupture which occured at several hours till days post operation after the patients had been back in the ICU,and 7 cases of early ruptur,which occured at the early stage of surgery,while the patient was still in the operation room.There were no cases of ruptures.The types of the ruptures were identified by operation or necropsy as 5 cases of type Ⅰ,4 cases of type Ⅱ,and 2 cases of type Ⅲ.Four patients were saved after emergency treatment,and 7 died.Conclusion It is difficult to repair left ventricle rupture,but effective prevention for onset can decrease its occurrence.The risk factors for left ventricular ruptures are female,advanced age,pathological changes characterized by mitral stenosis,small left ventricle (LVEDD < 35 mm),and low weight( <50 kg ).The following actions raise the risk of let ventricular rupture.Isolated replacement of the mitral valve than after double valve replacement or mitral valve replacement and coronary artery bypass graft; aggressive removal of calcification at the mitral valve; undue selection and replacement of mitral valve prostheses; large size of prosthetic valve with a high bioprosthetic angle in particular; deep sutures at the valve ring; aggressive traction or removal of papillary muscle,hematoma,and heart move.Also we should continue correcting unstable hemodynamic especially with very high blood pressure.Once left ventricular rupture occurs,extracorporeal circulation should be established as soon as possible,and direet suture or intracardiac and extracardiac repair suited to actual conditions are reliable ways to save the patient's life.

The effects of tetrandrine (Tet) on blood pressure, plasma renin activity (PRA) and the contractility of the papillary mascle and portal vein were studied in rats. After 4 d administration of Tet 30 mg/kg, 2/d, ig, blood pressure was decreased markedly in anesthetized male SD rats, but there were no effects on heart rate and PRA. A single dose of Tet 15 mg/kg iv reduced blood pressure and heart rate significantly, while did not change PRA. This single dose produced similar hypotensive effect in rats with and without pretreatment of Tet 30 mg/kg, 2/d, 4d, indicating the absence of tolerance. Tet inhibited the paced papillary muscle contractility and the spontaneous portal vein contractility, and the EC50 were 5.33?10-6mol/L and 4.25?10-5 mol/L, respectively. So the vascular selectivity of Tet is 0.12.

Hilar cholangiocarcinoma is a common bile duct cancer.The radical resection rate of end-stage malignancies reported in literature is about 20%.Half of the patients have lost the chance of operation at the time of care,while the average survival time in the patients who can not be operated is about six months.Therefore,for most patients,looking for a palliative treatment which can prolong the survival time is particularly important.From June 2013 to June 2014,our hospital applied iodine-125 brachytherapy,to treat 7 patients with unresectable hilar cholangio carcinoma.All the patients are still alive,the average survival time of 7 patients is 5.2 months up to now,with median survival time being 7.8 months,and longest survival time being 12 months.With good outcomes,few complications,as well as significantly prolonged survival time,iodine125 brachytherapy is regarded with broad clinical applications.
