Objective: Methylotropic yeast pichia pastoris system was used to express recombinant human soluble 4 1BBL protein with biological activity. Methods: According to the nuclear acid sequence coding human soluble 4 1BBL, we cloned the genes with PCR from XG 4 1BBL transfection cell line,then the gene fragment for extracellar domain was subcloned into the PUCm T vector and sequence of s4 1BBL cDNA was confirmed by sequencing. The s4 1BBL gene was inserted into the pPICZ?A , which was transformed into Pichia pastoris GS115 by linearized electroportion.The recombinant protein was identified by the assay of SDS PAGE and Western blot. Costimulating activity of rhs4 1BBL on T cell proliferation in vitro was evidenced by 3 H TdR incorporation assay. Results: The s4 1BBL cDNA was successfully obtained and insected into pPICZ?A. The protein molecular weight of hs4 1BBL in the yeast supernamant was about 21 kD by SDS PAGE analyses,and the specificitity was identified by western blot. Finally, rhs4 1BBL protein could costimulate the proliferation of T cells in vitro. Conclusion: The rhs4 1BBL protein was efficiently expressed in Pichia pastoris (GS115)and showed natural biological activities. And it may provide a valuable materials for further study of 4 1BB/4 1BBL.

BACKGROUNDColorectal surgery was regarded as one of the high risk surgery for post-operative deep vein thrombosis (DVT) and pulmonary embolism. This study aimed at investigating the incidence of venous thromboembolism (VTE) after colorectal surgery for malignancy.

METHODSData were collected from the prospective database of colorectal malignancy from 2000 to 2008. A total of 1421 colorectal (open and laparoscopic) operations were performed for the colorectal malignancy without DVT prophylaxis.

RESULTSOnly seven patients (0.5%) developed symptomatic DVT and one of them had complication of pulmonary embolism without mortality. Open operation for colorectal malignancy was identified as possible risk factor of DVT, however, risk factors like operative time, low anterior resection, sex, age etc. were not identified.

CONCLUSIONRisk of venous thromboembolism after colorectal operation is low in Chinese of our locality and it might be safe to perform colorectal operation for malignancy without DVT prophylaxis.

BACKGROUNDSingle incision laparoscopic colectomy has been performed in recent years, and has been shown to be feasible and safe. This study was to assess the feasibility of single incision laparoscopic right hemicolectomy and to compare the differences in different approaches.

METHODSThis retrospective study included eighteen patients with carcinoma of caecum and ascending colon, undergoing single incision laparoscopic right hemicolectomy. This study also compared single incision laparoscopic right hemicolectomy using different approaches: (1) single incision multiport, (2) single access port and (3) glove port.

RESULTSThere was no statistical difference in surgical outcomes. Concerning the surgeon's satisfaction toward three methods, overcrowding and durability were similar but the single incision multiport was associated with the highest gas-leak and the "glove" port was associated with poor durability. However, the method of single incision multiport has the lowest average cost of the special trocar or port in each operation. The operative time and blood loss of the operations in this study were comparable to previous publications.

CONCLUSIONThere was no significant difference between different approaches of single incision laparoscopic right hemicolectomy for colonic cancer in right side colon.

Objective To investigate the HIV drug resistance among HIV/AIDS patients who had received highly active antiretroviral treatment (HAATR) in Liangshan prefecture and related factors.Methods This investigation was conducted from August to October 2010.Data on epidemiology,treatment,CD4 + T cell,viral load and drug resistance tests were collected.Results 233 (73.50％) had a viral load of ＜ 1000 copy/ml,with the median CD4+T cell count as 329 cell/μl.26 samples appeared to be drug resistant,with the rate as 8.20％.Among 84 patients with antiviral therapy failure,the overall drug resistance rate was 30.95％(26/84).While 24 (28.57％) were resistant to non-nucleoside reverse transcriptase inhibitor (NNRTI) drugs.Among nucleoside reverse transcriptase inhibitors (NRTI),7 (8.33％) were resistant.1 (1.19％) had protease inhibitor (PI)resistance mutations identified.Factors that significantly associated with drug resistance would include:being injecting drug users (A OR =3.37,95 ％ CI:1.06-10.66,P =0.0390),having had chronic diarrhea ＞1 month (AOR=8.38,95％ CI:1.87-37.69,P=0.0055),having had CD4+T cell＜200(AOR=3.48,95％CI:1.29-9.39,P=0.0139),being residents from Butuo area (AOR=17.68,95％ CI:4.97-62.86,P＜0.0001 ).When comparing with other areas,data from Butuo showed that people who carried Yi ethnicity (AOR=17.35,95％ CI:2.01-149.73,P=0.0095) and were literate (having had primary or higher levels of education) (AOR=0.18,95％ CI:0.08-0.42,P＜0.0001 ),being married or having cohabited relations (AOR=8.17,95％ CI:2.35-28.39,P=0.001 ) were found to be less adherent (AOR=0.05,95％ CI:0.02-0.13,P＜0.0001) to the treatment.Conclusion Successful antiviral outcomes were seen among those AIDS patients under treatment,in Liangshan prefecture.Resistance rates were significantly different in regions.For IDUs,enforcement on subjects including prevention on drug resistance,adherence to HAART and treatment for drug addiction should be strengthened and programs being integrated.

OBJECTIVE: To evaluate the efficacy and safety of Cidan Capsule combined with adjuvant transarterial chemoembolization (TACE) in patients with a high risk of early recurrence after curative resection of hepatocellular carcinoma (HCC). METHODS: A multicenter, randomized controlled trial was conducted in patients with high-risk recurrence factors after curative resection of HCC from 9 medical centers between July 2014 and July 2018. Totally 249 patients were randomly assigned to TACE with or without Cidan Capsule administration groups by stratified block in a 1:1 ratio. Postoperative adjuvant TACE was given 4-5 weeks after hepatic resection in both groups. Additionally, 125 patients in the TACE plus Cidan group were administrated Cidan Capsule (0.27 g/capsule, 5 capsules every time, 4 times a day) for 6 months with a 24-month follow-up. Primary endpoints included disease-free survival (DFS) and tumor recurrence rate (TRR). Secondary endpoint was overall survival (OS). Any drug-related adverse events (AEs) were observed and recorded. RESULTS: As the data cutoff in July 9th, 2018, the median DFS was not reached in the TACE plus Cidan group and 234.0 days in the TACE group (hazard ratio, 0.420, 95% confidence interval, 0.290-0.608; P<0.01). The 1- and 2-year TRR in the TACE plus Cidan and TACE groups were 31.5%, 37.1%, and 60.8%, 63.4%, respectively (P<0.01). Median OS was not reached in both groups. The 1- and 2-year OS rates in TACE plus Cidan and TACE groups were 98.4%, 98.4%, and 89.5%, 87.9%, respectively (P<0.05). The most common grade 3-4 AEs included fatigue, abdominal pain, lumbar pain, and nausea. One serious AE was reported in 1 patient in the TACE plus Cidan group, the death was due to retroperitoneal mass hemorrhage and hemorrhagic shock, and was not related to study drug. CONCLUSIONS Cidan Capsule in combination with TACE can reduce the incidence of early recurrence in HCC patients at high-risk of recurrence after radical hepatectomy and may be an appropriate option in postoperative anti-recurrence treatment.
