Objective : To construct an appropriate technology catalogue for general practice based on Delphi method,and to provide reference for promoting appropriate techniques and training general practitioners. Methods : The catalogue was briefly constructed based on literature reviews and the data of the top twenty diseases diagnosed in out-patient department of Sir Run Run Shaw Hospital and two community health service centers in Hangzhou. Two-round Delphi consultation was conducted by fourteen general practitioners coming from upper first-class hospitals and community hospitals. The final catalogue was established according to evaluation of the degree of involvement,authority coefficient and Kendall's W values of the fourteen specialists. consultations : Results Of the fourteen specialists,nine had bachelor's degrees and five had master's degrees or above;twelve were deputy chief physicians or chief physicians and two were physicians. They were engaged in general practice for 17.21 years in average. The positive coefficients of the two rounds of were both 100.00%. The authority coefficient of the specialists was 0.891. After the first round of consultation,the W values for importance and feasibility of 6 first-class indicators were 0.170 and 0.244,and the ones of 56 second-class indicators were 0.236 and 0.250（all P<0.05）. Six of second-class indicators were excluded because their coefficent of variation（CV）for importance and feasibility were more than 0.25. After the second round of consultation,the W values for importance and feasibility of 6 first-class indicators were 0.245 and 0.247,and the ones of 50 second-class indicators were 0.355 and 0.370（all P<0.05）. The CV for each indicator was less than 0.25. Finally,an instructional catalogue was defined,consisting of 6 first-class indicators（basic diagnosis and treatment skills,first aid skills,symptomatic diagnosis and treatment skills,chronic disease management skills,common disease diagnosis and treatment skills,and common manipulative skills）and 50 second-class indicators. Conclusion The degrees of involvement,authority and consistency of the specialists were relatively high. The catalogue of appropriate technology for general practitice had good reliability and feasibility,which was worthy of promotion and application.

This paper was to study the angiogenic inhibitory effect and the potential antitumor effect of the constructed recombinant DNA vaccine CRT/HPV6bE7 in vivo. The C57BL/6 mice were vaccinated respectively with recombinant CRT/HPV6bE7 DNA plamids. The inhibitory effects on angiogenesis of generated vaccines in vivo were evaluated by a bFGF-induced angiogenesis assay using the Matrigel kit. To investigate the potential antitumor effect, the mean tumor weights, sizes and tumor appearing times were measured in C57BL/6 mice treated with HPV6bE7-expressing B16 cells. The results indicated that the recombinants CRT180/HPV6bE7 and CRT180 showed strong anti-angiogenic effects in bFGF-induced angiogenesis in vivo. Moreover, CRT180/HPV6bE7 and CRT180 DNA vaccines could significantly inhibit the tumor growth in tumor challenge experiment, and CRT180/HPV6bE7 was superior to other vaccines in delaying tumor formation time, limiting tumor size and weight in tumor protection experiment. In conclusion, recombinant CRT180/HPV6bE7 DNA could elicit a most efficient anti-angiogenic effect and inhibit tumor growth in mice inoculated with DNA vaccines. The antiangiogenic activity of CRT were suggested residing in a domain between CRT 120-180 aa.

Proteasome inhibitors have shown remarkable success in the treatment of hematologic neoplasm. There has been a lot of attention to applying these drugs for solid tumor treatment. Recent preclinical study has signified the effectiveness on cell proliferation inhibition in lung adenocarcinoma treated by carfilzomib (CFZ), a second generation proteasome inhibitor. However, no insight has been gained regarding the mechanism. In this study, we have systematically investigated the CFZ functions in cell proliferation and growth, cell cycle arrest, and apoptosis in lung adenocarcinoma cells. Flow cytometry experiments showed that CFZ significantly induced G2/M cell cycle arrest and apoptosis in lung adenocarcinoma. MTS and colony formation assays revealed that CFZ substantially inhibited survival of lung adenocarcinoma cells. All results were consistently correlated to the upregulation expression of Gadd45a, which is an important gene in modulating cell cycle arrest and apoptosis in response to physiologic and environmental stresses. Here, upregulation of Gadd45a expression was observed after CFZ treatment. Knocking down Gadd45a expression suppressed G2/M arrest and apoptosis in CFZ-treated cells, and reduced cytotoxicity of this drug. The protein expression analysis has further identified that the AKT/FOXO3a pathway is involved in Gadd45a upregulation after CFZ treatment. These findings unveil a novel mechanism of proteasome inhibitor in anti-solid tumor activity, and shed light on novel preferable therapeutic strategy for lung adenocarcinoma. We believe that Gadd45a expression can be a highly promising candidate predictor in evaluating the efficacy of proteasome inhibitors in solid tumor therapy.

OBJECTIVETo explore the feasibility of single-incision laparoscopic totally extraperitoneal hernioplasty (SILS-TEP) with self-made port for repairing of inguinal hernia.

METHODSSILS-TEP was performed in 7 inguinal hernia patients (9 sides) with conventional laparoscopic instruments and self-made port, which composed of a wound retractor, surgical gloves and 3 ordinary trocars. The clinical data and follow-up results of 7 cases were retrospectively collected and analyzed.

RESULTSThe self-made port was applied for SILS-TEP uneventfully without the need of additional ports in all 7 patients (9 inguinal hernias). The median operating time was 90. 0 (70-125) min, intraoperative blood loss was 10. 0 (5. 0-20. 0) mL and postoperative hospital stay was 2.0 (2. 0-4. 0) d. The median pain scores of visual analog scale (VAS) at 6 h,12 h, 24 h and 14 d were 3(2~4), 2(1~2), 1(0~2) and 0(0~1), respectively. There were no intraoperative complications reported, and all patients were satisfied with wound healing. No hernia recurrence was observed during the 3-months of follow-up.

CONCLUSIONOur initial experiences show that SILS-TEP with self-made port is a safe and feasible surgery, which can simplify the procedure with available equipments and reduce the cost, therefore can be applied in grass-root hospitals.

OBJECTIVETo investigate the clinical effect of laparoscopic radical resection of colon cancer.

METHODSPatients with colon cancer who underwent radical resection during January 2000 to January 2004 in Sir Run Run Shaw Hospital (Medical College of Zhejiang University) were divided into open and laparoscopic groups for a non-randomized case-control study. All the patients were followed up and their clinical and pathological results were compared.

RESULTSNo difference was seen between the two groups on the patients' age, gender, lymph node numbers and Dukes staging. The laparoscopic group had a longer mean operation time [(182 +/- 62) min vs (141 +/- 37) min] and shorter hospital stay [(5.3 +/- 1.9) d vs (8.2 +/- 1.2) d] than the open group. All surgical margins were pathological negative. Post-operation follow up was 12-18 months (mean 21 months). No incision recurrence was found in neither group. As far the local recurrence and distal metastasis rate were similar in both groups.

CONCLUSIONSLaparoscopic radical resection of colon cancer has minimal invasion and shorter recuperation than open procedure, the radicalness and either local recurrence or distal metastasis rate after surgery are similar when compared with open group.

OBJECTIVETo explore the mucosal protective effect on the quality of gastric ulcer healing.

METHODSGastric ulcers were induced in male rats by serosal application of acetic acid. Rats were gavaged for 14 days with saline, omeprazole (OME), teprenone (TEP) and TEP plus OME starting 3 days after ulcer induction. Then the tissues and blood samples were obtained and measured.

RESULTThe lower ulcer index (UI) and increased ulcer inhibition rate were observed in OME and OME+TEP groups. In TEP and OME+TEP groups, restored mucosa thickness increased, cystically dilated glands decreased, microvessels in connective tissue increased, the secretion of mucus, hexosamine, PGE(2), bFGF were enhanced, the expression of EGFR was increased.

CONCLUSIONTEP can improve the quality of gastric ulcer healing, when combined with OME,the effect is more marked.
