Objective To explore the clinical efficacy of laparoscopic gastric ulcer perforation repair com-bined with Helicobacter pylori(Hp)cure.Methods Laparoscopic repair was used in the treatment of gastric ulcer perforation in 45 cases,and 42 cases of postoperative infection were combined Hp eradication therapy.Results The average operative time was 52.5min (36 -83min),mean blood 17.2mL(8 -45mL)in the 45 patients,with no sig-nificant intraoperative complications.The mean 4.5d (3 -8d)normally discharged after an average follow -up of 25 months (18 to 36 months)without significant complications and recurrent perforation.In 42 cases infected with Hp,cure rate of 97.6%,inefficiency of 3.4%,2 -year recurrence rate of 4.9%.Conclusion Laparoscopic gastric ulcer perforation is a minimally invasive,safe and effective surgical method.The surgery is simple,minimal trauma, less pain,faster recovery and fewer complications,Hp infected radical surgery combined with Hp eradication has good efficacy,less recurrence and important clinical significance and value.

Objective To explore the effects of simvastatin on the protein expressions of urokinase-typeplasminogen activator (uPA) and plasminogen activator inhibitor-1 (PAI-1). Methods Male Sprague–Dawley rats were divided into saline group , LPS group and LPS plus simvastatin group , and were then pretreated with simvastatin (1 mg/kg) for 30 minutes before addition of LPS (8 mg/kg). Changes in left ventricular pressure were recorded. Ninety minutes after LPS injection, whole blood was collected from the inferior vena cava, and neutrophils were separated. The neutrophils were then lysed to detect levels of uPA and PAI-1. Results Left ventricular systolic pressure (LVSP: mmHg), maximal differential of left ventricular pressure (+dp/dtmax:mmHg/s), and heart rate (beats/min) were markedly decreased at different time points after administration of LPS, and maximal differential of left ventricular pressure increased in the rats receiving LPS as compared with those receiving saline, although the differences between the control and LPS groups were not statistically significant. LPS caused a great decline in uPA content and an elevation in PAI-1 content in neutrophils, but simvastatin diminished the impact of LPS on neutrophils. Conclusion Simvastatin plays a role in protection of cardiac function in rats with LPS-induced septic shock , and controls expressions of uPA and PAI-1 in neutrophils.

Lung distension belongs to chronic obstructive pulmonary disease (COPD) in modern medicine.In recent years,its disease incidence and mortality have increased year by year.Supported by the traditional Chinese medicine (TCM) standardization of the State Administration of TCM project-TCM preventive treatment practice guidelines-prevention of lung distension recrudescence,the first draft of the TCM Preventive Treatment Practice Guideline on Prevention of Lung Distension Recrudescence was formulated on the basis of preventive treatment theory,evidences from both ancient and modern literatures,and through the Delphi method as well as expert consensus conference.And then,peer review comments were collected,which laid the foundation for the further improvement of this guideline.This guideline was aimed to achieve the industry consensus,to improve the quality of life (QoL) in patients of the stable period,to reduce the economic burden of patients,as well as to improve both the theoretical connotation and practical value of preventive treatment in TCM.

A PCR method was used to amplify the sequence encoding the mature peptide of?-mannanase of Bacillus subtilis. The gene was inserted into the Pichia pastoris vector pPIC9K, downstream of?-factor signal peptide sequence. The resultant recombinant plasmid pPIC9K-MAN was lineared by BglII digestion and introduced into the host Pichia pastoris GS115 by PEG method. After screen, the recombinant P. pastoris strain MAN22 was obtained and fermented in large scale 5L fermenter. The recombinant mannanase activity could reach to 1102IU/ml. The properties of the recombinant mannanase were characterized.

Objective To study whether ferulic acid can promote healing on chronic ischemic wounds and its possible mechanisms.Methods 40 male New Zealand white rabbits were randomly divided into 4 groups:vaseline group,ischemic control group,5％ ferulic acid group and recombinant bovine basic fibroblast growth factor for external use (rb-bFGF) group.Gross wounds were carefully observed and HE staining was used to observe the wound healing and immumohistochemical staining to observe the expression of the VEGF and CD31.The RNA was extracted to detect the expression of VEGF and HIF-1a by real-time PCR.Results The general observation and the HE staining of each specimen 11 days after operation all indicated that the duration of wound healing of the 5 ％ ferulic acid group was similar to that of the rb-bFGF group and markedly shorter than the ischemic control group and the vaseline smear group.The result of the immunohistochemical staining indicated that the content of the VEGF and CD31 expression of the 5 ％ ferulic acid groups and the rb-bFGF group made lit tle difference,but there was markedly less VEGF and CD31 in ischemic control group and the vaseline smear group.The result of the PCR showed that expression level of VEGF and HIF-1α in the 5 ％ fer ulic acid group was similar to that in the rb bFGF group and the vaseline smear group,but was obviously more than that of the ischemic control group and the vaseline smear group (P ＜ 0.05).Conclusions Ferulic acid can promote angiogenesis by increasing VEGF and HIF-1α which are closely related to angiogenesis and then promote the healing of chronic wounds.

Objective: High mobility group box 3 (HMGB3) plays an important role in the development of various cancer. This study aims to explore whether HMGB3 regulates cervical cancer (CC) progression and elucidate the underlying mechanism. Methods: HMGB3 expression in clinical patients' tumor samples were determined by real-time quantitative polymerase chain reaction (qRT-PCR) and western blot. HMGB3 overexpression/knockdown were used to investigate its function. Cell apoptosis and cycle were detected by Annexin V/PI staining and flow cytometry. In vivo tumor model was made by subcutaneous injection of HeLa cells transfected with shRNAs targeting HMGB3 (shHMGB31) into the flank area of nude mice. Western blot was used to detect the levels of β-catenin, c-Myc, and matrix metalloproteinase-7 (MMP-7) in Hela and CaSki cells transfected with sh-HMGB3 or shRNAs targeting β-catenin. Results: Both messenger RNA and protein levels of HMGB3 were upregulated in CC tissues from patients. High expression level of HMGB3 had positive correlation with serosal invasion, lymph metastasis, and tumor sizes in CC patient. Functional experiments showed that HMGB3 could promote CC cell proliferation both in vitro and in vivo. The expression levels of c-Myc and MMP-7 were increased, resulting in regulating cell apoptosis, cell cycle, and activating Wnt/β-catenin pathway. Conclusions Our data indicated that HMGB3 may serve as an oncoprotein. It could be used as a potential prognostic marker and represent a promising therapeutic strategy for CC treatment.
