Objective: To compare the safety and efifcacy of rivaroxaban and warfarin for treating the patients with left ventricular thrombus. Methods: A total of 31 patients with left ventricular thrombus were studied, the patients were randomly divided into 2 groups:Warfarin group, n=16, the patients initially received oral warfarin and low molecular weight heparin at (2.5-3) mg/day, when the INR value reached 2.0-3.0, heparin was stopped and warfarin was continued, the INR value was monitored every 3 days for 3 times, when INR value was stably kept at 2.0-3.0, it was then monitored for every 2 weeks. Rivaroxaban group,n=15, the patients received oral rivaroxaban at 10 mg twice a day. All patients were followed-up for 3 months, the thrombus remission time, new onset of thrombosis, embolism and bleeding events during treatment period were compared between 2 groups. Results: The patients’ age, gender, complication, size of thrombus and medication were similar between 2 groups. Compared with Warfarin group, Rivaroxaban group had the shorter thrombus remission time, (60.00±5.50)d vs (71.00±8.50) d,P<0.01, while the new onset of thrombosis and embolism events as cerebral embolism and systemic embolism were similar between 2 groups, Warfarin group had slightly higher bleeding events, allP>0.05. Conclusion: Rivaroxaban had better effect than warfarin for treating the patients with left ventricular thrombus without increasing the risk of bleeding.

Objective To compare the different effect of two gastric tube insertion methods in pa-dents undergoing computed tomographic virtual endoscopy. Methods 56 patients undergoing computed tomographic virtual endoscopy were randomly divided into group A and B according to gastric tube insertion methods, group A inserted gastric tube to descending duodenum by gastroscope, group B inserted by Jag precursor via nose. One- time success rate and the incidence rate of side effect were compared between the two groups. X2 test was adopted. Results One- time success rate of group A and B was 33.3%, 82.9% respectively, with obvious statistic difference. The incidence rate of side effect of group A was higher than that of group B. Conclusions Inserting gastric tube to descending duodenum by Jag precursor via nose is convenient, time- saving, causing less pain and resulting in higher success rate.

Xuesaitong injection was intravenous dripped to patients in the treatment group with 200 mg/d for 10 days. Results The total effective rate was 97.7% in the treatment group and 80.3%in the control group. There was significant difference between the two groups (P＜0.05). Conclusion Integrated therapy of xuesaitong injection and ratine Western Medicine has a great efficacy in treating patients with stable angina pectoris.

BACKGROUND:Heart transplantation is an effective method for treatment of end-stage heart failure, but immune rejection that seriously impact therapeutic effacicy is easy to occur after transplantation. OBJECTIVE:To investigate the regulatory effect of bone marrow mesenchymal stem cel s on the immune function of rats undergoiong heart transplantation. METHODS:Twenty Lewis rats were enrol ed as donors, and 20 Wistar rats as recipients. Heart transplantation models were established in the Wistar rats. These 20 model rats were randomized into cel transplantation and control group with 10 rats in each group. Forty-eight hours after heart transplantation, rats in the cel transplantation group were given bone marrow mesenchymal stem cel suspension (1 mL, 2×108 cel s/L) via the tail vein, while rats in the control group were given normal saline in the same dose. Then, the expression levels of serum interleukin-2, interleukin-10 and percentage of CD4+, CD8+, CD4+/CD8+, CD4+CD25high, CD4+CD25high Foxp3+T cel s in the venous blood were detected in the two groups at 7 days after cel transplantation. Additional y, rat myocardial tissues were taken and observed pathological y. RESULTS AND CONCLUSION:The survival time of the cel transplantation group was significantly longer than that of the control group (P<0.05). The expression level of interleukin-2 showed no significant difference between the two groups (P>0.05), but the level of interleukin-10 in the cel transplantation group was significantly higher than that in the control group (P<0.05). Compared with the control group, the percentage of CD4+/CD8+, CD4+CD25high, CD4+CD25high Foxp3+and CD4+T cel s was significantly higher, and the percentage of CD8+T cel s was significantly lower in the cel transplantation group (P<0.05). Histopathological findings showed that there were a smal amount of infiltrated lymphocytes in the cel transplantation group with the presence of slight bleeding and edema, and these inflammatory reactions were milder than those in the control group. These findings indicate that bone marrow mesenchymal stem cel transplantation can effectively reduce the rejection in rats undergoing heart transplantation.

Gut microbiota is essential to human health,playing a major role in the bidirectional communication between the gastrointestinal tract and the central nervous system through the immunological,hormonal,neural and metabolic pathways.The colonization of the gut microbiota is influenced by multiple and diverse factors,such as the perinatal factors,dietary habits,diseases and antibiotics.The infant is the critical period for modifying the gut microbiota,disruptions during this period of microbiota-host interaction have the potential to affect the development and function of the brain.To regulate the homeostasis of the gut microbiota has its profound influences on improving the symptoms of gastrointestinal and behavior disorders.

OBJECTIVE: To explore the biological characteristics of tendon and performance of repair materials for tendon defects. METHODS: CNKI and Medline database were retrieved by computer for papers published between 1985 and 2009. Literature concerning biological characteristics and performance of repair materials for tendon defects were selected. Meta analysis, irrespective papers or repetitiveness studies were excluded. Totally 29 papers were included after screening and evaluating including 16 in Chinese and 13 in English. The biological characteristics of tendon and performance of repair materials were summarized.RESULTS: Nutrition for tendon mainly supplied by blood, and the tendon fatigue would be occurred with repeatability loads. Compared to other tissue-engineered materials, tendon possesses self-repair ability. The biological characteristics of tendon was closely associated with collagen fiber, which exhibited similar stress-strain curves, namely, characteristics of viscoelasticity body--hysteresis, creep and stress relaxation. Currently, main repair materials for tendon defects comprised autogenous tendons, allogeneic tendon, artificial tendon and tissue engineered tendon.CONCLUSION: Many materials can be used in tendon repair with distinct advantage and disadvantage; however, there is not an ideal repair method. With the development of tissue and gene engineering, the optimal substitute for tendon would be prepared.
