The clinical practice on real patients is more and more difficult in the present condition of the hospitals.The application of the simulating teaching system in clinical cardiovascular teaching can improve the study-activity,and develop studnets'ability to practice.

In teaching of intra-arterial thrombolysis of ischemic stroke, introducing the method of problem-based learning ( PBL ) to improve the students' learning initiative and stimulate the students' interest in search of knowledge, and guide students to form scientific clinical thinking. Through further participation in surgery, promoting the combination of theory and practice. PBL can help to improve students' ability to analyze and solve problems related to intra-arterial thrombolysis of ischemic stroke.

AIM: To observe the effect of oxymatrine on sodium channel in isolated cardiomyocytes of guinea pig. METHODS: Single ventricular myocytes of guinea pigs were obtained by enzymatic dissociation. The whole - cell patch clamp recording technique was used to record the change of sodium current by different dosage of oxymatrine from 1 to 1 000 ?mol?L-1 . RESULTS: Oxymatrine decreased sodium current in a dose - dependent manner. Oxymatrine (100 ?mol?L-1) decreased the current density by 40% (P

The apparatus for intrinsic dissolution test recorded in United States Pharmacopeia (USP) integrating with fiber-optic drug dissolution test system (FODT) were used to real-time monitor intrinsic dissolution processes of alliin in four media which were water, solution of HCl with pH 1.2, buffer solution of acetate with pH 4.5, and buffer solution of phosphate with pH 6.8. The intrinsic dissolution rate (IDR) and the similarity factor (f2) of two intrinsic dissolution curves with two apparatuses were calculated. The IDR values of alliin with rotating disk system were 28.1.3, 33.55, 28.38 and 30.95 mg x cm(-2) x min(-1) in four media, respectively. And the IDR values of alliin with stationary disk system were 44.16, 47.07, 45.11 and 51.34 mg x cm(-2) x min(-1), respectively. The similarity factors were 56.42, 50.75, 40.30 and 40.64, respectively. The results showed that the intrinsic alliin dissolution rates were much greater than 1 mg x cm(-2) x min(-1). It inferred that alliin dissolution would not be the rate limiting step to absorption.

Neurogenic bladder caused by herpes zoster is not common.An 86 years old male patient with 6 months of dysuria and urinary retention caused by herpes zoster underwent sacral neuromodulation (SNM) operation. The symptoms of dysuria and fecal incontinence were improved significantly after operation.

ObjectiveTo investigate the clinical efficacy of moxibustion plus medicinal tea in treating gouty arthritis during the interictal period.MethodA treatment group of 64 patients received moxibustion plus medicinal tea and the control groupof 64 patients, alimentary control.ResultThe total efficacy rate was 95.3% in the treatment group and 75.0% in the control group; there was a statistically significant difference between the two groups (P<0.01).ConclusionMoxibustion plus medicinal tea has a better therapeutic effect on gouty arthritis during the interictal period.

AIM:To investigate the effect of atorvastatin on myocardial apoptosis , ventricular remodeling and cardiac function after acute myocardial infarction (AMI) in diabetic rats, and to explore whether the effect is mediated by hepatocyte growth factor ( HGF)/c-Met signaling pathway .METHODS:Diabetes in 70 male SD rats was induced by in-traperitoneal injection of streptozotocin (STZ, 65 mg/kg).After 8 weeks, AMI was induced by the ligation of the left ante-rior descending coronary artery in the diabetic rats , and 32 surviving rats were divided into AMI group (n=16) and AMI+atorvastatin group ( n=16, 20 mg· kg -1 · d-1 ) at random.The similar surgical procedure was completed in sham group (n=11) without coronary ligation.Atorvastatin was given daily by gavage from the first day after AMI .Two weeks later, the cardiac function , pathological changes of myocardial tissues , myocardial apoptosis , and the expression of HGF and c-Met were compared among groups .RESULTS: AMI significantly reduced cardiac function , increased collagen volume fraction ( CVF) and myocardial apoptotic index , and up-regulated the expression of HGF and c-Met at mRNA and protein levels in AMI control group (P<0.05).The cardiac function was improved , and CVF and myocardial apoptotic index were reduced by the treatment with atorvastatin , which also up-regulated the expression of HGF and c-Met (P<0.05).CON-CLUSION:Atorvastatin significantly attenuates myocardial apoptosis and cardiac remodeling , and improves cardiac func-tion after AMI in diabetic rats by further enhancing the activation of HGF /c-Met pathway .

BACKGROUND:Autologous bone marrow mesenchymal stem cel transplantation for the treatment of cardiovascular disease has become one of the hotspots, but it is unclear whether the proliferation and directional differentiation of autologous bone marrow mesenchymal stem cels varies changes with age. OBJECTIVE: To explore the proliferation and differentiation changes of rat bone mesenchymal stem cels in different ages. METHODS:The bone marrow mesenchymal stem cels from Sprague-Dawley rats in different age groups were purified and cultured, and then examined by flow cytometry in terms of cel cycle. Meanwhile, neonatal rat cardiomyocytes were co-cultured with bone marrow mesenchymal stem cels. The morphologic changes of bone marrow mesenchymal stem cels and the protein expression of troponin T were detected with immunofluorescence technique. RESULTS AND CONCLUSION: The percentage of bone marrow mesenchymal stem cels in G0/G1 phase was increased with age; while the percentage of expression of troponin T proteins-positive bone marrow mesenchymal stem cels were decreased with age. These findings indicate that the proliferation and differentiation abilities of rat bone marrow mesenchymal stem cels descend with age.

OBJECTIVE:To investigate clinical efficacy and safety of meglumine adenosine cyclophosphate in the treatment of acute myocardium infarction. METHODS:A total of 80 patients with acute myocardium infarction in our hospital during May 2015-Jan. 2016 were selected and divided into control group and observation group according to random number table,40 cases in each group. Control group was given conventional treatment. Observation group was additionally given Meglumine adenosine cyclo-phosphate injection 120 mg added into 5% Glucose injection 250 mL,ivgtt,qd,on the basis of control group. Both groups re-ceived treatment for 7 d. Clinical efficacies as well as the levels of serum hs-CRP and NT-proBNP before and after treatment were observed in 2 groups,and the occurrence of ADR was compared between 2 groups. RESULTS:Total response rate of observation group(92.50%)was significantly higher than that of control group(75.00%),with statistical significance(P<0.05). Before treat-ment,there was no statistical significance in the serum levels of hs-CRP or NT-proBNP between 2 groups(P>0.05). After treat-ment,the serum levels of hs-CRP and NT-proBNP in 2 groups were decreased significantly,and the observation group was signifi-cantly lower than the control group,with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Meglumine adenosine cyclophosphate shows significant therapeutic efficacy for acute myocardium infarction,reduces serum levels of hs-CRP and NT-proBNP significantly with good safety.
