AIM: To investigate the electrophysiological changes of diabetic myocardium and effects of cyclovirobuxine D (CVB-D) on its electrophysiology. METHODS: Diabetes was induced in male SD rats, using a single injection of alloxan into tail vein. Untreated age-matched animals were used as controls. Animal electrocardiogram (ECG) was recorded by 2 weeks. Effects of CVB-D on isolated right ventricular papillary muscle from experimental diabetic rats and control group were observed by recording the transmembrane potentials with conventional glass microelectrodes. RESULTS: QT intervals in ECG and action potential duration (APD) at all levels were significantly lengthened in myocardium from week 2 of diabetes. Within the concentration of 13.3-63.3 ?mol?L~(-1), CVB-D prologated APD of diabetes in dose-dependent manner and more than that of control. Within the concentration of 33.3-63.3 ?mol?L~(-1), CVB-D depressed RP, APA, V_(max) and OS of diabetes in dose-dependent way and more than that of control. In addition, CVB-D at concentration of 20 ?mol?L~(-1) prologated APD in a time-dependent manner. The most prologation of APD was attained about 40 min in control, while more than 40 min in diabetes. CONCLUSION: The results show that QT intervals in ECG and APD at all levels are significantly lengthened in myocardium from week 2 of diabetes. CVB-D prolongates APD and inhibits RP, APA, OS and V_(max) more in diabetes than in control.

Objective To study the different oral compound polyethylene glycol electrolyte powder on the effect of bowel preparation before colonoscopy.Methods A total of 602 inpatients or outpatients were selected from department of gastroenterology,and they were randomly divided into tranditional group(n =288)and improvement group(n =314).All patients took a dose of two box of compound polyethylene glycol electrolyte powder 4 hours before colonoscopy.Endoscopic doctor investigated the antibiotic tolerance,adverse reactions,heart rate,blood pressure,blood electrolytes and blood glucose during treatment in form of questionnaire with single blind Bosdon bowel preparation scale (BBPS)score.Results The BBPS scores of the tranditional group and improvement group were (7.03 ± 1.24)points,(7.82 ±1.12)points,the score of the improvement group was significantly higher than the traditional group(t =2.259,P <0.05).The taste scores were (1.89 ±0.07)points,(1.25 ±0.09)points (t =2.624,P <0.05),the fully taking rates were 90.28%,95.86%(χ2 =7.375,P <0.05 ),and the second taking rates were 88.54%,93.95%(χ2 =5.566,P <0.05).In contract,the score of adverse reactions of the improvement group was significantly lower than that of the traditional group [(2.58 ±0.07)points vs(2.22 ±0.09)points,t =2.068,P <0.05].There was no significant difference of colonoscopy time between the two groups[(10.78 ±4.34)min vs (9.89 ± 1.77)min,t =1.766,P >0.05 ],althought the improvement group was shorter than the tranditional group. Conclusion The modified way of oral compound polyethylene glycol electrolyte powder not only can improve the qulity of intestinal cleaning,but also acts as a more effective method in preparation of colonoscopy due to its high tolerance, good comfort,less pain and high acceptance of patients.Therefore,it is worthy of clinical promotion and application.

The higher medical education in China starts late and needs further exploration and improvement.While in Germany,it is elite education with a long history.Compared with China,in curriculum setting,Sociology,Medical health security,Humanities and Social Sciences and Organ system classification courses are more emphasized,and in terms of degree,it only has Doctor degree but with higher quality in Germany.Higher medical education in China will also take the path of the elite education.We can learn from the German medical education development experience and pay attention to solving the lack of the curriculum by supplementing social medicine and medical health security,increase the autonomy of the instructors in the training process,strengthen the medical students' social responsibility,and improve the quality of higher medical education in China.

BACKGROUND:It has been an urgent problem of how to promote cartilage repair of the knee and shorten the total course through a tissue engineering approach. Fortunately, microfracture plus stem cel transplantation may open up a new path for this issue. OBJECTIVE:To investigate the clinic feasibility of arthroscopic microfracture technique plus stem cel transplantation for repair of articular cartilage injury of the knee. METHODS:From October 2010 to March 2012, a total of 16 patients with articular cartilage injury of the knee were enrol ed, including 12 males and 4 females, with the average age of 38.6 years (16-52). Al cases of cartilage injury were confirmed by arthroscopy. Autologous bone marrow was extracted from patients at 2 weeks before treatment to isolate, culture and amplify bone marrow mesenchymal stem cel s in vitro. The cel culture solution of 3-5 mL (about 107 cel s) was harvested. The articular cavity was clean by arthroscopy and microfracture technique was performed at the area of cartilage injury that was then covered with hemostatic gauze through a minimal y invasive incision and the prepared bone marrow mesenchymal stem cel s were injected. The knee was bandaged with the elastic bandage after aspirating the joint cavity effusion by vacuum suction. Functional exercises were performed early by CPM.RESULTS AND CONCLUSION:After fol ow-up of 4-18 months, there were 13 cases of excel ent, 2 cases of valid and 1 case of ineffective. According to Lysholm knee scores, the average scores were improved from 42 points (33-67 points) to 89 points (75-99 points) at 4 weeks after treatment. The function was satisfied and al patients were fol owed up without recurrence or worse. Under the arthroscopy, the combination of microfracture technique and autologous bone marrow mesenchymal stem cel transplantation is proved to be effective for articular cartilage injury of the knee and it can notably improve the clinic symptoms and recover the function of the knee.

BACKGROUND:After knee joint replacement, patients are often treated with Rivaroxaban and Enoxaparin Sodium for postoperative anticoagulation, avoiding the formation of deep vein thrombosis in lower limbs. OBJECTIVE:To explore the application effects of different anticoagulant drugs in patients with knee joint replacement. METHODS:Ninety patients underwent knee joint replacement in Xiangya Second Hospital of Central South University from July 2011 to July 2014, were randomly divided into two groups, with 45 patients in each group. The experimental group was treated with Rivaroxaban, while the control group was treated with Enoxaparin. RESULTS AND CONCLUSION:Postoperative drainage volume, total blood transfusion, bleeding index, quantity of blood platelet, activated partial thromboplastin time, thrombin reduction time, whole blood viscosity, plasma viscosity, D-dimer coagulation index, HSS score at postoperative 2 weeks, average ecchymosis area, average thigh circumference, and average leg circumference were significantly better in the experimental group, than in the control group (P<0.05). The incidence of deep vein thrombosis of lower limbs in the experimental group was lower than that in the control group (P<0.05). Experimental findings indicate that, both Rivaroxaban and Enoxaparin can exert anticoagulation effect during the knee joint replacement, and Rivaroxaban is better.

Objective To explore the related pelvic floor anatomy to the pathological vaginal relaxation and key points of the vaginal tightening surgery.Methods The vaginal tightening surgery was performed in 24 cases of vaginal relaxation.The key points of this operation included levator ani muscle suturation and perineal body reconstruction,and anal sphincter reconstruction as in case of the muscle injury grade Ⅲ.Results The degree of levator ani muscle separation was positively correlated with that of vaginal relaxation in all the 24 cases.18 cases were followed up from 6 months to 2 years,and had no complications of rectovaginal fistula and infections.The average level of perineal body was increased from 2.3 cm to 3.5 cm.Vaginal length of 6 cm from vaginal orifice was proper with good tightness.The patients felt strong anal contraction,enhanced ability of vaginal tightening and improved quality of sex life.There were no more infections of genitourinary tract.Conclusions Through levator ani muscle suturation and perineal body reconstruction,it can get the vaginal tightening effect.

Objective To compare the efficiency of enhanced T2* weighted angiography (ESWAN) sequence with that of a conventional T2*-weighted gradient-recalled-echo (GRE T2*WI) sequence for the detection of hemorrhagic shearing lesions in patients with diffuse axonal injury (DAI). And combined with MRI parameters, to further discuss the principles and virtues of ESWAN sequence. Methods Seventeen patients with DAI were enrolled in this study. The raw data acquired from ESWAN scan were postprocessed by using the mean square root of multi-echoes. Then, the postprocessed images were compared with the conventional GRE T2* weighted images. The global and regional (superficial, deep and posterior fossa) lesion numbers determined by both sequences were compared by using Wilcoxon signed ranks test (two-tailed). Differences were considered to be significant at P≤0.05. Results Hemorrhagic lesions were more obvious on ESWAN images than those on conventional GRE T2* weighted images. The median and range value of the detected lesion numbers on ESWAN images were 27 and (1-239) in whole brain, 13 and (1-89) in cerebral superficial region, 5 and (0-111) in cerebral deep region and 1 and (0-39) in posterior fossa region, respectively; whereas, on GRE T2* weighted images, they were 7 and (1-34) in whole brain, 5 and (1-27) in cerebral superficial region, 2 and (0-25) in cerebral deep region and 0 and (0-4) in posterior fossa region, respectively. There were significant statistical differences between the two sequences in revealing the lesions in all the four regions (Z=-3.519,-3.182,-3.185,-2.677,P＜0.05). Conclusion In ESWAN sequence, multi-echo acquisition ensured sufficient magnetic susceptibility for detecting small hemorrhagic lesions. So, ESWAN is more sensitive to small hemorrhage, which revealed more hemorrhagic lesions than conventional GRE T2*WI and presented more valuable information for the diagnosis of DAI.
