Objective: To study the effect of helicobacter pylori on gastric mucosal cell proliferation in gastritis. Methods: Fifty-six gastritis patients with or without Helicobacter pylori infection (Hp+ 27; Hp- 29) were selected. The expression of proliferation cell nuclear antigen (PCNA), epidermal growth factor receptor (EGFR), transforming growth factor beta receptor type Ⅰand typeⅡ(TGF?RⅠ, TGF?RⅡ) in gastric mucosa were examined by immunohistochemical method. Results: The PCNA and EGFR were significantly higher in Hp positive chronic gastritis patients than in Hp negative ones(P

Objective To observe the level of autophagy induced by TRAIL in TT cell line and identify the role of autophagy in TRAIL-inducing apoptosis of TT cell line.Methods The growth inhibition of TT cells was measured by MTT assay.MDC staining was used to identify the happening of autophagy.Annexin V/PI double staining was used to analyze the apoptosis rate of TT cells by flowcytometry.The protein expression of caspase-8 and Beclin1 was detected by Western blot.Results ① The growth inhibition ratio of TT cells induced by TRAIL at the concentration of 250,500,1000 and 2000 ng/ml was (3.02 ± 1.82)％,(4.87 ± 1.45)％,(7.51 ± 1.57) ％,(12.76 ± 3.23) ％ respectively,which suggested significant resistance of TT cells to TRAIL.② MDC-labeled green light vesicles was significantly increased after the treatment of TRAIL for 48 h.③ The apoptosis rate of TT cells induced by TRAIL at the concentration of 500 ng/ml and 1000 ng/ml after the pretreat ment of 3-MA for 4 h was(17.83 ± 1.54) ％ and(27.81 ± 1.79) ％ respectively,which was significantly higher than the apoptosis rate induced by TRAIL(3.70 ± 0.34) ％,(6.55 ± 0.59) ％ alone and that induced by 3-MA(7.71 ± 0.64) ％ (t =3.282,P ＜ 0.05 ; t =7.830,P ＜ 0.01).④ The combination treatment of TRAIL and 3-MA increased the cleavage of caspase-8 and down-regulated the expression of Beclin 1.Conclusion Autophagy induced by TRAIL may contributes to the resistance of TT cells to TRAIL,which can be reversed by the inhibition of autophagy.

Objective To study the effect and related mechanism of celecoxib on tumor necrosis factorrelated apoptosis-inducing ligand(TRAIL) induced apoptosis of medullary thyroid cancer TT cell line.Methods MTT assay was used to measure the growth inhibition induced by TRAIL and celecoxib alone and their combination.TT cell cycle distribution was analyzed by flowcytometry.Hochest33258 staining and DNA ladder was used to detect the apoptosis of drug combination on TT cells.Western blot was used detect the protein change of cyclin A,Cdk2,caspase-8,c-FLIP,and RIP.Results ①MTT showed the growth inhibition ratio of TT cell intervened by the combination of TRAIL and celecoxib was 47.53％ ± 1.34％,which was much higher than that intervened by TRAIL(7.75 ％ ± 3.84％)and celecoxib alone.The differences had statistical significance (t test,F =5.234,P ＜0.01);②PI detection found the cells' number in G0/G1 phase in celecoxib group and combination group were increased compared to that in control group and TRAIL group(F =242.694,P ＜ 0.01);③Western blot indicated the expression of Cyclin A and Cdk2 were down regulated,there was no statistic significance;④ The apoptosis morph in nuclus was detected by Hochest33258 staining and showed the karyopycnosis and muclear fragmentation were increased in combination group with the apoptosis rate 24.23％ ± 2.91％,which was much higher than that in TRAIL(5.86％ ± 1.41％) and celecoxib(20％ ± 1.24％) (t test,F =1.824,P ＜0.01),the difference has statistic significance;⑤Western blot illustrated the active schizolysis of casplase-8 was higher and the expression of c-FLIP and RIP was down regulated in combination group.Conclusion celecoxib plays a positive effect on TRAIL-reduced apoptosis of medullary thyroid cancer TT cell line,which may due to the cell cycle arrest at G0/G1 phase,down-regulation of c-FLIP and RIP and subsequent activation of caspase-8.

In order to obtain the serotype distribution of E.coli from duck and to screen the vaccine bacterial strains,the serotype identifications and biological characteristics of E.coli were analyzed in recent years from Shandong,Hebei and other areas of commercial duck field;selections of vaccine strains were detected by the virulence and immunogenicity.Totally 44 isolated bacterial strains of E.coli from duck were identified to a total of six serotypes:O78,O93,O76,O2,O92 and O32.The O78 serotype was the dominant serotype,accounting for 56.8％ (25/44);O93 serotype for 15.9％ (7/44) according to bacterial Oantigen typing.The strain SD (O78 serotype) was confirmed to have strong virulence and good immunogenicity.The O78,O93 and O76 are the dominant serotypes of duck E.coli in the study areas.The SD strain could be used as the candidate for the next development of inactivated vaccine.

Objective To evaluate the efficacy and safety of minimally invasive percutaneous nephrolithotomy combined with negative pressure system in one-stage treatment of calculus pyonephrosis.Methods Eighty-three cases of calculus pyonephrosis,including 15 upper ureteral calculus cases,9 renal pelvis calculus cases,28 multiple calculus cases and 31 staghorn calculus cases,were retrospectively analysed.The diameter of the stone was from 1.2 to 6.3 cm.All the patients were punctured under X-ray or ultrasound guidance and established an access of 20 F.A 12 F nephroscope,combined with negative pressure system,was inserted to the collecting system to suck off the liquor pus.The stone was fragmented by pneumatic lithotripsy or holmium laser lithotripsy at one-stage.Negative pressure system was used to reduce the intrapelvic pressure during the operation.Results All the patients were treated successfully.The average operative time was 34 ± 19 min.The upper ureteral calculus and renal pelvis calculus cases were all stonefree at one-stage treatment.Of the other 59 cases,33 cases were stone-free and 26 cases need a secondlook.The total stone free rate was 68.7％(57/83)at one-stage and 91.6％(76/83)at second-look.Only 7 patients had fever after operation and no patient had sepsis or shock.Conclusion Combined with negative pressure system,minimally invasive percutaueous nephrolithotomy via a 20 F tract is safe and effective for one-stage treatment of calculus pyonephrosis.

Objective To detect Helicobacter pylori (H.pylori) multiple antibodies of urease (Ure),cytotoxin associated gene A protein (CagA),vacuolating toxin A (VacA),heat shock protein 60 (Hap60) and nitroreductase ( RdxA),and disclose their relations with chronic gastritis,peptic ulcer and gastric cancer.Methods A volume (3 ml) of venous blood was taken from 300 patients of gastroduodenal disease diagnosed by endoscopy,to centrifuge and detect antibodies of Ure,CagA,VacA,Hsp60,RdxA by protein chip technique.Results The infective rates of H.pylori in chronic gastritis,peptic ulcer,and gastric cancer were 34.0％,58.0％,34.0％ ( P ＜ 0.01 ),respectively.In the H.pylori positive chronic gastritis,peptic ulcer and gastric cancer,the positive rates of CagA antibody were 54.9％,75.9％,64.7％ ( P =0.070) ; the positive rates of VacA antibody were 31.4％,22.4％,17.6％ ( P =0.412) ;and the positive rates of Hap60 antibody were 56.9％,48.3％,41.2％ ( P =0.466),respectively.The total positive rate of RdxA antibody was 4.0％ (5/126).Conclusions H.pylori infection and virulence factor CagA are closely related to peptic ulcer,while it did not show the exact correlation between VacA,Hsp60 and gastroduodenal disease.The level of RdxA antibody can not represent the level of H.pylori resistance to metronidazole.

BACKGROUNDRRM1 may be a prognostic factor in non-small cell lung cancer (NSCLC). The aim of this study is to evaluate RRM1 expression and prognosis in NSCLC by the means of tissue microarray.

METHODSA total of 417 paraffin-embedded specimens of NSCLC from Lung Cancer Study Center in Guangdong Provincial People's Hospital were collected and tissue microarray was constructed. RRM1 expression was detected by SP method and its correlation with prognosis was evaluated.

RESULTSNo statistic difference was found in RRM1 expression in different gender, age, tumor site, histology, differentiation, T stage, N stage, M stage and pTNM stage groups (P > 0.05). Univariate analysis showed that RRM1 was not an independent prognostic factor (P > 0.05). At the multivariate analysis, differentiation and N stage were considered independent prognostic factors.

CONCLUSIONSRRM1 expression detected by immunohistology is not an independent prognostic factor in NSCLC. TNM stage is still the best prognostic factor up to now.
