Objective To prepare monoclonal antibody against Prostate Stem Cell Antigen(PSCA) and explore the inhibitory effects of Anti-PSCA mAb in treatments of human prostate cancer xenografts in mice. Methods Balb/c mice were immunized by PC-3 cell line. After fusing and screening, the anti-PSCA McAb’s characterizations were determined. Solid tumors in mice were produced by subcutaneous injection with PC-3 cells in the flanks of the mice.We picked out 10 mice bearing human prostate cancer xenografts.They were divided into a treatment group (n_1=5) and a control group (n_2=5).200 ?g Anti-PSCA mAb was injected into abdominal cavity of each mouse of the treatment group and PBS for them of the control group.Anti-PSCA mAb and PBS were administered once every three days for consecutive three times.The mice survival conditions of two groups were recorded during 5 weeks.The serum PSA, the tumor weights and dimensions of survived mice were measured.The tumor volume inhibition rate was calculated. T-test was performed to compare differences of PSA in serum,tumor weights and volumes between the treatment and control groups.Routine pathological slides of tumor tissue were observed under light microscope to evaluate the range of tumor tissues damaged by Anti-PSCA mAb. Ultrastructure was observed with transmission electron microscope. Results A marine McAb was produced, which raised against PSCA,belonged to IgG1 subclass. The average PSA serum level of the two groups were(3.28?0.55)ng/ml and(7.26?0.43)ng/ml.The weights of tumors of the two groups were(0.95?0.17)g and(3.08?0.18)g.The volumes of them were(164.59?14.08)mm3 and(548.49?19.79)mm3.There are remarkable differences between the treatment group and the control group(P

Objective To investigate the clinical efficacy of ilaprazole and bismuth combined ten-day standard quadruple therapy and sequential therapy in the treatment of patients with Helicobacter pylori (H .pylori)infected chronic gastritis.Methods A total of 200 patients with H .pylori-positive chronic gastritis diagnosed by gastroendoscopy examination and rapid urease test (RUT)were randomly divided into standard quadruple therapy group and sequential therapy group,100 cases in each group.One group received ilaprazole,bismuth,amoxicillin-clavulanatepotassium and ofloxacin 10-day standard quadruple therapy, and the other group received ilaprazole, amoxicillin-clavulanatepotassium, ofloxacin and furazolidone 10-day sequential therapy.In four to six weeks after the therapy,the condition of H .pylori eradication was detected by a 14 C-urea breath test.The improvement of clinical symptoms and adverse effects were also observed. Normal distributed and variance homogenized measurement data were compared by t test,while unordered categorical data were analyzed by chi-square test and the exact probability method,and categorical data were compared by two independent sample rank sum test.Results The per-protocol analysis values of H .pylori eradication rates of the standard quadruple therapy group and the sequential therapy group were 88.54%(85/96)and 87.23%(82/94),respectively,while the intention-to-treat analysis values were 85 .00%(85/100)and 82.00%(82/100 ),respectively.The effective rates of symptomatic relief of upper abdominal pain,acid regurgitation,heart burning in the standard quadruple therapy group and the sequential therapy group were 95 .83%(92/96)and 95 .74%(90/94),respectively. The incidence of adverse effects which weve very mild was 6.25 % (6/96 ) and 7.44% (7/94 ), respectively.There was no statistically significant difference in the above three factors between the two groups (all P >0.05).Conclusions Ilaprazole and bismuth combined 10-day standard quadruple therapy and sequential therapy in the treatment of patients with H .pylori positive chronic gastritis both achieves high rates of H .pylori eradication and symptom relief with mild adverse effects.

Objective The incidence of alcoholic fatty liver increases year by year in recent years .The aim of this study was to establish an animal model of AFL to investigate the pathogenesis of hepatic fibrosis . Methods This study involved 40 male Japa-nese rabbits aged (17.01 ±1.54) d and weighing 1.00-1.52 kg, which were equally randomized to an experimental group and a control group.The animals in the former group received lavage of 10 mL of 50%ethanol twice a day, with normal feedstuff and water, while those in the control group received normal feedstuff and water only .We performed ultrasonography for dynamic liver presentation before and at 12, 16, and 20 weeks after feeding, followed by pathological observation of the livers . Results After 12 weeks of eth-anol garage , fatty liver was observed in 18 of the rabbits and it deteriorated with the prolonged time of administration . The body weight was significantly decreased in the experimental rabbits as com-pared with the controls at 16 weeks ([2.48 ±0.30] vs [2.78 ± 0.15] kg, P<0.05) and 20 weeks ([2.61 ±0.44] vs [3.10 ± 0.13] kg, P<0.05).Ultrasound and pathological grading showed 1 mild, 3 moderate, and 13 severe cases of fatty liver in the experimen-tal group, but none in the control , and pathological examination re-
vealed similar results (1 mild, 4 moderate, and 12 severe cases of fatty liver) in the former group.At 20 weeks, alcoholic fatty liver was found mainly in the S3-S4 stage. Conclusion Alcoholic fatty liver models could be successfully established in rabbits by etha-nol garage and ultrasonography is useful for monitoring the development and progression of the condition .

Objective To investigate the expression and significance of γH2AX in cervical squamous carcinoma.Methods Firstly,DNA were extracted from 74 cervical squamous carcinoma samples and PCR were tested for HPV infection.Secondly,formalin-fixed paraffin-embedded tissue sections (4 μm)were stained with H&E method to detect cervical lesions grading.Thirdly,HPV16 DNA were examined by in situ hybridization(ISH) and γH2AX,p16 were examined by immunohistochemical (IHC) staining.Then,30 cases typical tissue sections in which including the normal cervical tissue,cervical intraepithelial neoplasia and cervical carcinoma in situ were selected for comparing the HPV DNA loading,and the γH2AX and,pl6 expression.Finally,the feasibility of γH2AX serving as a biomarks in HPV infection-related cervical carcinogenesis were analyzed.Results In this study,HPV infection ratio is 98.65％,and HPV16 is the most common type with 74.32％ infection.In situ hybridization showed no HPV16 DNA exist in normal cervical tissues and CINI.In CIN Ⅱ HPV DNA exist mainly as episomal DNA.With the increasing of cervical lesions grade,HPV DNA was integrated into chromosome steadily.The expression of γH2AX and pl6 were positively associated with grading of cervical lesions.HPV DNA and γH2AX protein co-exist primarily in the prickle cell layer and the granular cell layer.The HPV DNA and p16 protein exist in different cell layer.Conclusion γH2AX may be employed as a biomarker for HPV positive cervical carcinogenesis.

Objective:To evaluate the role of autophagy in ischemia postconditioning (IPO)-induced attenuation of intestinal ischemia-reperfusion (I/R) injury in mice.Methods:Thirty-two SPF healthy adult male C57BL/6J mice, aged 9-12 weeks, weighing 25-29 g, were divided into 4 groups ( n=8 each) using a random number table method: sham operation group (group S), intestinal I/R group (group IIR), group IPO and IPO plus 3-methyladenine (3-MA) group (group IPO+ 3-MA). The model of intestinal I/R was established by occlusion of superior mesenteric artery for 45 min followed by 2-h reperfusion in anesthetized animals.The mice underwent 3 cycles of 30-s reperfusion followed by 30-s ischemia before restoration of reperfusion in group IPO.Blood samples from the femoral artery were collected at 2 h of reperfusion for determination of concentrations of serum diamine oxidase (DAO), D-lactate (D-LA) and intestinal fatty acid binding protein (I-FABP). The animals were then sacrificed and intestinal tissues were removed for microscopic examination of the pathologic changes which were scored according to Chiu and for determination of the expression of autophagy-related proteins Beclin-1 and p62 (by Western blot). The water content of intestinal tissues was calculated. Results:Compared with group S, the Chiu′s score, concentrations of serum DAO, D-LA and I-FABP, water content of intestinal tissues, and LC3Ⅱ/LC3Ⅰ ratio were significantly increased, Beclin-1 expression was up-regulated, and p62 expression was down-regulated in IIR, IPO and IPO+ 3-MA groups ( P<0.05). Compared with group IIR, the Chiu′s score, concentrations of serum DAO, D-LA and I-FABP, water content of intestinal tissues, and LC3Ⅱ/LC3Ⅰ ratio were significantly decreased, Beclin-1 expression was up-regulated, and p62 expression was down-regulated in group IPO ( P<0.05). Compared with group IPO, the Chiu′s score, concentrations of serum DAO, D-LA and I-FABP, and water content of intestinal tissues were significantly increased, LC3Ⅱ/LC3Ⅰratio was decreased, Beclin-1 expression was down-regulated, and p62 expression was up-regulated in group IPO+ 3-MA ( P<0.05). Conclusion:Autophagy is involved in ischemia postconditioning-induced attenuation of intestinal I/R injury in mice.
