Objective To evaluate the effects of rabeprazole-based triple therapy for associated gastric ulcer caused by the helicobacter pylori(Hp) infection. Methods 100 patients with associated gastric ulcer caused by the Hp infection were randomly divided into treatment group and control group. The treatment group was given rabeprazole-based triple therapy( rabeprazole 10mg bid, amoxicillin 1.0g bid and clarithromycin 500mg bid), and the control group was given omeprazole-based triple therapy( omeprazole 20mg bid, amoxicillin 1.0g bid and clarithromycin 500mg bid). The two groups were given 7 days treatment. Results The total effective rate of clinical symptoms of treatment group was 96. 0% ,the healing rate of the treatment group was 88.0%, the total effective rate of gastroscopy effect of treatment group was 94.0% ,the Hp clearance rate of treatment group was 92.0% and the Hp eradication rate of treatment group was 90. 0% ,which were higher than the control group,but the difference was not significant( P ＞ 0. 05 ). The two groups had no significant adverse reactions. Conclusion Rabeprazole-based triple therapy for associated gastric ulcer caused by the Hp infection was effective, safe and worth popularization and application.

Objective To explore the interventional effect of two different methods in the prevention of chemotherapy phlebitis caused by 5-fluorouracil.Methods Eighty cases of patients treated with cisplatin+5-fluorouracil (PF) chemotherapy in the First Affiliated Hospital of Guangxi Medical University from May 2015 to July 2016 were selected and divided into the observation group and control group according to admission time,40 cases in each group.The observation group was smeared with 2% anisodamine along the direction of vein puncture after peripheral venous puncture success,while the control group was smeared with mucopolysaccharide polysulphate emulsion paste.The occurrence of phlebitis and degree of local pain after intervention were compared between the two groups.The blood biochemical indexes and inflammatory factors levels before and after intervention were compared too.Results After the intervention,the distribution of phlebitis level and local pain degree had statistical difference between the two groups (Z=2.57,2.53;P=0.01);the observation group was superior to the control group in the aspects of phlebitis lesion degree and local pain alleviation;WBC,MPV and PDW in the observation group had statistical difference between before and after intervention;WBC,PLT and PCT in the control group had statistical difference between before and after intervention (P<0.05);PLT count was positively correlated with PCT in the two groups (r=0.952,P<0.05);the CRP level and WBC count after intervention had no statistical difference between the two groups(P>0.05).Conclusion 2% anisodamine can effectively prevent and alleviate the occurrence of 5-FU caused chemotherapy phlebitis and local pain.At the same time,PLT can provide a basis for preventing chemotherapy phlebitis.

Objective To study the expression of Notch 1,Jagged1 and Notch intracellular domain (NICD) in epithelial ovarian carcinoma tissues and analyze the clinical significance.To explore the activity of γ-secretase in epithelial ovarian carcinoma cell line SKOV3 and the effect of N-[N-(3,5-dil uorophenacetyl)-L-alanyl]-S-phenylglycine t-butyl ester (DAPT),a γ-secretase inhibitor on the activity of γ-secretase in SKOV3.Methods Immunohistochemistry staining method was performed in 43 patients with epithelial ovarian carcinoma and 11 patients with benign epithelial ovarian tumor to detect the expression of Notch1,Jagged1 and NICD.The differences of expressionof Notch1,Jagged1 and NICD between malignant and benign ovarian tumors was compared and alsoanalyzed the correlation with clinicopathological parameters of ovarian carcinoma.Human serous ovarian cancer cell line SKOV3 and immortalized nontumorigenic ovarian epithelial cell line T29 were incubated in vitro.The activities of γ-secretase in SKOV3 and T29 with dimethyl sulfoxide (DMSO) and DAPT were detected respectively by Gal4VP16/UAS and dual luciferase reporter assay system.Results (1) The immunohistochemical composite scores (ICS) of Notch1 in epithelial ovarian carcinoma (6.7±2.2) were not significantly different with those in benign epithelial ovarian tumor (5.4± 2.7,P=0.153),while the ICS of Jagged 1 and NICD in epithelial ovarian carcinoma (5.3± 2.4,5.3± 2.3) were higher than those in benign epithelial ovarian tumor (1.6± 1.4,3.1± 1.7; all P＜0.01).The expression of Notch 1,Jagged 1 and N ICD had no correlation with patients' aged,history of carcinoma,ascites,the level of serum CA125,maximum length of ovarian tumor,Federation International of Gynecology and Obstetrics (FIGO) stage,grade and pathology subtypes (all P＞0.05).The hazard ratio between the high expression of Notch1,Jagged1,or NICD and the moderate to low expression of Notch1,Jagged1,or NICD,and Jagged1 were 0.771,1.648 and 1.316,respectively (all P＞0.05).The 5-year survival rate and median survival time between the high expression of Notch,Jagged 1 or NICD in subgroup and moderate to low expression in subgroup were of no difference (all P＞0.05).The activity of γ-secretase in SKOV3 was significantly higher than that in T29 [(12.2± 1.4)％,P=0.019].(2)After DAPT treated,the relative activity of γ-secretase in SKOV3 (50 μmol/L) was declined from (100.0±5.3)％ to (6.6±0.8)％ (P=0.001).Conclusions Jagged1 and NICD in Notch1 pathway may play a key role in the occurrence of ovarian carcinoma.The activity of γ-secretase in epithelial ovarian carcinoma was higher than that in ovarian epithelial cell which suggest that DAPT,γ-secretase inhibitor,may become the target of ovarian carcinoma treatment.

Objective To study the expression and clinical significance of Notch3 and Notch intracellular domain (NICD) in ovarian carcinoma and the effects of N-[N-(3 ,5-difluorophenyl) acetyl-L-alanyl]-S-phenyl glycine t-butyl ester (DAPT), a γ-secretase inhibitor on the proliferation and apoptosis in OVCAR3, A2780 ovarian carcinoma cell lines. Methods Western blot was used to detect the expression of NICD in the tissues from 58 ovarian carcinomas patients and 21 normal ovarie, who were admitted in Peking University First Hospital from July 2006 to June 2009. Immunohistochemistry was also used to detect the expression of Notch3 in these tissues. The relationship with clinical features of ovarian carcinoma was also analyzed. Proliferation of OVCAR3 and A2780 ovarian cancer cells was determined by methyl thiazolyl tetrazolium (MTT) assay, cell cycles and apoptosis and index of proliferation were detected by flow cytometry method. The expression of NICD in OVCAR3 and A2780 cells incubated with DAPT was detected by western blot. Results (1)The expression level of NICD in ovarian carcinomas was significantly higher than that in normal ovarian tissues (1.64 ±0. 19 vs. 0.98 ±0.20;P <0.05). The NICD expression was higher in ovarian cancers with low grade or advanced stage than those in high-middle grade or early stage,respectively (1.90 ± 0. 22 vs. 1.25 ± 0. 21,1.80 ± 0. 21 vs. 1.21 ± 0. 15; all P < 0. 05). The Notch3 protein was stained positively in cytoplasm, nuclear and cell membrane. The expression of Notch3 was higher in ovarian carcinomas than that in normal ovaries [78% (45/58) vs. 24% (5/21); P < 0. 01]. While,there were no stasistical difference in different pathological types, stages, differentiation of ovarian carcinoma. There was no difference between the patients with adjuvant chemotherapy or not. (2)After OVCAR3 and A2780 cells incubated with DAPT 24, 48, 72 hours, NICD expression was significantly lower than that in control group (P < 0. 05). The effects of DAPT inhibited the proliferation and prompted the apoptosis of OVCAR3 and A2780 cells were depended on the concentrations and times. Conclusions Notch3 and NICD may play a key role in the occurrence and progress of ovarian carcinoma. The mechanism of DAPT inhibited the proliferation and prompted the apoptosis of OVCAR3 and A2780 cells may be due to decreased the formation of NICD.

Objective To investigate the methodology and feasibility of an anatomic survey of fetal limbs in the first trimester. Methods In this study, 533 normal fetus and 6 fetal corpse without limb abnormalities form June 2011 to August 2012 underwent an anatomic survey on the limbs in our consultation center. The limbs were scanned using a systematic continuous sequence approach:(1) Displaying upper arm and humerus, forearms and radius/ulna, hands in proximal to distal direction. (2) The thigh and femur, crus and tibia/fibula, feet was attempted from the sagittal section of each structure. (3) If the whole limb couldn′t be visualized in a section then the three segments will be demonstrated respectively. The position and move-ment also should be observed during the scan. Data were collected regarding gestation age, examining time and the structures. Results The limbs except toes of 533 normal fetus were clearly observed, which was completely unaffected by gestational age, with the mean time of scanning is 98.6±37.4 s (rang:36-189 s). The structures (including upper arms and humerus, forearms ,radius and ulna, hands, thigh and femur, crus and tibia, fibula, feet) of fetal limbs were clearly observed on the 6 fetal corpse, but the ossification center of fingers were steadily visualized until 13 weeks and toes after 13 weeks. Conclusions Scanning fetal limbs in the first trimester were feasible by a systematic continuous sequence approach in a short period of time.
