Objective To understand the relationship between Hp infection and treatment role in perioperative period patients with liver cirrhosis.Methods Hp in gastric juice and ammonia concentration in blood were examined in 32 patients with liver cirrhosis.Results ⑴The rate of Hp infection was 62 1% in 32 patients with liver cirrhosis.⑵There was no obviously difference in the blood ammonia concentration between both patients with Hp positive and negative.⑶The blood ammonia concentration after Hp eradication was significantly lower than that before eradication.Conclusions Hp infection could partly contribute to occur the hyperammoniaemia in patients with liver cirrhosis.Hp should be checked routinely in perioperative period patients with liver cirrhosis.The eradication of Hp is necessary to prevent and treat the hyperammoniaemia in operative patients with liver cirrhosis.

Objective To evaluate the effect of LC+LCBDE and EST+LC in treating the cho-leeystolithiasis with choledocholithiasis. Methods The clinical data of 256 patients treated in our hos-pital were retrospectively analyzed. Of the 256 patients, 132 were treated by LC+LCBDE and 124 by EST combined with LC. The clinical data of the two groups was compared in operation success rate, operation time and cost, complication rate and operative hospital stay. Results There was no statisti-cal difference in the operation success rate, complication rate, operative hospital stay between 2 groups. However, there were significant differences in the operation time and cost between the 2 gruops. Conclusion There are respective indications, advantages and disadvantages in the two groups. EST+LC is the better choice for patients with a CBD<1.0 cm in diameter, stones impacted in the distal CBD, or old age. Otherwise, the better way is LC+LCBDE for patients with a CBD>1. 0 cm in diameter and multiple choledocholithiasis, especially in young and middle-aged people.

Objective To evaluate the effect of laparoscopic cholecystectomy(LC) combined with bile duct exploration and stone removal(BDE) and LC with endoscopic sphincterotomy(EST) in treating cholecystolithiasis with choledocholithiasis.Methods Among 256 cases of cholecystolithiasis and choledocholithlasis,132 patients were treated by LC+LCBDE,and 124 cases by EST combined with LC.The operation success rate,operation time and cost,complication rate,and length of hospital stay of the two groups were compared.Results There was no statistical difference in the operation success rate,complication rate,stone clearance rate,and average hospital stay between the two groups,but EST+LC group had significantly longer operation time and higher cost.Conclusions There are respective indications,advantages and disadvantages in the two groups.EST+LC is the better choice for patients with diameter of CBD1.0cm and with multiple choledocholithiasis,especially for middle-aged patients,the better way is LC+LCBDE.

AIM:To screen the miRNA related to blood stasis syndrome and to explore the genetic mechanism of blood stasis syndrome in hypertension.METHODS:Human umbilical vein endothelial cell line CRL-1730 was co-cul-tured with the human sera from healthy normal controls and hypertension patients to establish a blood stasis-hypertension cell modela.The hypertension patients showed qi deficiency and blood stasis, qi stagnation and blood stasis, cold retaining and blood stasis, heat retaining and blood stasis and non-blood stasis syndromes.The endothelial cell models of blood stasis in hypertension were established.Target cells were collected for total RNA extraction.The techniques of Solexa ( high-throughput sequencing method) and digital gene expression profiling were applied for screening the target miRNA, and miRWalk software was used for online prediction the mRNA which might be the relevant target.qRT-PCR was conducted to confirm the prediction.RESULTS:SAT1-Hsa-miR-199a-5p and ATF4-Hsa-miR-1283 were found to be highly expressed in these cell models.The expression of miR-1283 and miR-199a-5p was confirmed by qRT-PCR.CONCLUSION:miR-199a-5p and miR-1283 may be the relevant miRNA for the prediction of blood stasis syndrome in hypertension.

Objective To establish a new murine model of experimental autoimmune myositis by immunizing with MYBPC2 protein. Methods The purified Myosin-binding protein C, fast type (MYBPC2) was emulsified with complete Freundˊs adjuvant, then C57BL/6 mice were immunized by multi-point subcutaneous injection (0, 7 days), and intraperitoneal injection of pertussis toxin 2 μg simultaneously. The pathological changes of mice with different immunizing dose at the preconceived time were ex-plored. Mean-while, mice were immunized with 600 μg each time, and the muscle endurance was tested on the 21th day. The expression of major histocompatibility complex (MHC) class-Ⅰ and the surface biomarkers of the inflammatory cells in muscle tissues were observed. Mann-Whitney U test was used for statistical analysis. Results ① With the increase of immunizing dosage, muscle damage and inflammation tended to be more serious. On the 21th and 28th day, muscle lesions were most significant. Muscle fiber degeneration and necrosis and inflammatory cell infiltration could be seen in the experimental group. ② Compared with the control group, muscle endurance of mice in the experimental group decreased significantly [(6.1 ±1.3) min versus (9.2±1.6) min, U=2.00, P=0.017]. The MHC class-Ⅰ on the muscle fiber surface of the experimental group was positive, scattered infiltration of CD4 +, CD8+ T ly-mphocytes and CD68 + macrophages between muscle fibers and around the vascular areas could be observed, and CD20+B lymphocytes mainly distributed in the area around the blood vessels, nevertheless rarely seen between muscle fibers. Conclusion Exper-imental autoimmune myositis models of mice have been successfully induced by immunizing with MYBPC2 in China for the first time, and similar clinical and pathological features of human polymyositis could be observed. This new model can be used for studying the pathogenesis of autoimmune myositis.
