Objective To evaluate the effect of rapamycin on proliferation and cell cycle of human bladder cancer cell line 5637. Methods Total?ly 5637 cells were maintained in RPMI 1640 containing 10%fetal bovine serum,100 U/mL penicillin and 100μg/mL streptomycin for adherent cul?ture. Cells were grown at 37℃in a 5%CO2 incubator. The 5637 cells were treated with various concentrations of rapamycin solution(50 nmol/L, 100 nmol/L,200 nmol/L,and 400 nmol/L). The control group was daily treated with single RPMI 1640 without medication. The growth repression rate for 5637 cells was evaluated by MTT. Flow cytometry was used to investigate the effect of rapamycin of different concentrations on cell cycle of 5637 cells. Results Compared to the control group,rapamycin can inhibit the proliferation of 5637 cells in a concentration and time dependent manner. Rapamycin inhibited 5637 cells at G0/G1 thus inhibiting cell proliferation but not inducing apoptosis. Conclusion Rapamycin inhibited growth of 5637 bladder carcinoma cells and arrested cell cycle at G0/G1,indicating that mammalian target of rapamycin may play an important role in proliferation of 5637 cells and act as a new tumor therapeutic target in patients with bladder cancer.

Mitochondrial fusion,fission and dynamic transformation between the two are commonly known as mito-chondrial dynamics. Mitochondrial fusion-fission is related to a variety of biological functions of mitochondria inclu-ding regulation of energy metabolism, production of reactive oxygen species, maintenance of Ca2+homeostasis and influence of cellular death. Cardiac development,energy metabolism and ion homeostasis are closely related to the balance of mitochondrial fusion-fission.Mitochondrial fusion-fission disorders may cause myocardial cell dysfunction, damage and even the death of myocardial cells,which result in heart failure ultimately. Developing medicines tar-getting to reconstruct the balance of mitochondrial fusion-fission may provide new ideas and strategies for the treat-ment of chronic heart failure.

AIMTo investigate the influence of L-arginine (NO donors, L-Arg) on spontaneous contractions of ileum in mice and study the effects of activation of beta-adrenoceptor on NO-induced inhibition in spontaneous contractions of ileum.

METHODSThe method of spontaneous contractions recording was used to investigate the effect of L-NNA, ODQ, Isoprenaline( beta-adrenoceptor agonist) and Propranolol (beta-adrenoceptor antagonist) on NO-induced inhibition in spontaneous contractions of ileum.

RESULTS(1) L-Arg inhibited the spontaneous contractions of ileum and had concentration-response relationship. (2) L-NNA (3 x 10(-4) mol/L), ODQ (3 x 10(-6) mol/L) relieved the inhibitory effect of L-Arg in ileum . (3) Propronalol (3 x 10(-6) mol/L) decreased significantly the inhibitory effect of L-Arg. (4) Iso (1 x 10(-7) mol/L) increased the inhibitory effect of L-Arg. After Iso (1 x 10(-7) mol/L) and Propronalol (3 x 10(-6) mol/L) being coapplied, the inhibitory effect of L-Arg was not changed.

CONCLUSIONNOS catalyzed L-Arg and produced NO. NO exerted its inhibitory effect by the cGMP pathway, the activation of beta-adrenoceptor was partly involved in NO-induced relaxation in ileum.

Objective To explore the factors associated with severe hand-food-mouth disease (HFMD) case in Shanghai.Methods A total of 105 severe HFMD cases diagnosed from May to July,2011 in Shanghai were enrolled as case group while another 210 mild HFMD cases were randomly selected as control group in the same period.All subject' s parents or babysitters were asked to fill in the questionnaire in which including demography,ways of babysitting,behavior and the like.All HFMD cases were diagnosed by both clinical symptom and nuclear acid testing.Data was processed by EpiData (V3.0) and analyzed by SPSS (V17.0).Results Factors as age,gender,Diaspora pattern,migrant,size of house,numbers of family member,numbers of children,frequency of seeing doctor,dishware that sharing with babysitter,food chewed by babysitter,dirty hand,EV71 virus type and diagnosis on HFMD in the fist visit to hospital were found associated with severe HFMD by univariate analysis.Results through multivariate logistic regression showed that factors including:being the only male kid,more than 3 children in the family,dirty hands,unable to be diagnosed as HFMD in the first visit to the hospital,visiting doctor during the past 6 months for 2 and 3 times etc.could be kept in the model with statistical threshold of 0.05.Adjusted ORs and confidence intervals of them were 2.431 ( 1.317-4.487),2.661 (1.332-5.315),3.403 ( 1.871-6.191 ),6.607 (3.011-14.500),2.431 ( 1.111-5.321 ),2.628 ( 1.137-6.071 ) respectively.Being Infected by EV71 was also found a very important risk factor compared with CoxA16 or other enteroviruses,and its adjusted OR was 5.614 (2.409-13.082).Conclusion It was necessary to implement molecular diagnosis for identifying the virus type of HFMD,together with improvement on the capacity of clinical diagnosis in order to diagnose the HFMD cases earlier.More attention should be paid to these HFMD cases with EV71 infection as well as prompting frequent visits to hospitals on those families with more children.

Objective To explore the expression of glutathione hormone (GSH) and γ-glutamyl cysteine synthetase (γ-GCS) in premature newborn rats exposed to hyperoxia,and to study antioxidant role of GSH and γ-GCS in hyperoxia-induced lung injury.Methods One-day old preterm SD rats were divided randomly into 2 groups:hyperoxia group and air group.Newborn rats in hyperoxia group were continuously exposed to oxygen(oxygen ＞ 850 mL/L),and newborn rats in air group were exposed in room air.After 1,7,14 days of exposure,the preterm SD rats of 2 groups were killed,and whole lung of these rats were isolated.GSH and γ-GCS of pulmonary tissue homogenate were detected by double antibody sandwich enzyme linked immunosorbent assay (ELISA).Bicinchoninic acid (BCA) was used to detect GSH protein in lung tissue homogenate.Total lung RNA was extracted and γ-GCS mRNA was detected by reverse transcription polymerase chain reaction.Results 1.The results were detected by ELISA method and BCA method,compaired with air group,the expression of GSH protein in lung tissue induced by hyperoxia was significantly increased after 1,7 days of exposure(all P ＜ 0.05),but the expression of GSH became significantly weak after 14 days of exposure (P ＜0.05).2.The expression of γ-GCS mRNA and protein level were significantly increased in 1,7 days (all P ＜0.05),but the general tendency decreased after 14 days of exposure,the expression of γ-GCS mRNA became stronger than its expression after 14 days of air group,both were no significantly different(P ＞0.05).Conclusions The changes of GSH and γ-GCS in the lung of premature SD rats induced by oxidation outbreak participate in the development of hyperoxia-induced lung injury,the activity of γ-GCS may be increased by hyperoxia,and alleviate hyperoxia lung injury in premature rats through antioxidation of GSH.

Objective:To investigate the effects of docetaxel for postoperative chemotherapy of advanced gastric cancer.Methods:The propensity score matching and retrospective cohort study was conducted. The clinicopathological data of 311 patients with advanced gastric cancer who were admitted to Lanzhou University Second Hospital from January 2013 to December 2018 were collected. There were 224 males and 87 females, aged from 26 to 82 years, with a median age of 58 years. Of 311 patients, 204 cases undergoing chemotherapy with the FOLFOX regimen (oxaliplatin, calcium folinate, 5-fluorouracil) were allocated into the FOLFOX group, and 107 cases undergoing chemotherapy with the FLOT regimen (docetaxel, oxaliplatin, calcium folinate, 5-fluorouracil) were allocated into the FLOT group. Observation indicators: (1) the propensity score matching conditions and comparison of general data between the two groups of patients after matching; (2) follow-up; (3) analysis of survival factors; (4) subgroup analysis; (5) adverse reactions. Follow-up was performed using a combination of outpatient examination, hospitalization review and telephone interview to detect situations of patients chemotherapy, postoperative survival, tumor recurrence and metastasis up to February 2019. The propensity score matching was realized using the nearest neighbor method with 1: 1 ratio and caliper setting as 0.02. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact probability method. Rank data was analyzed using non parametric Rank sum test. The survival curve and rate were respectively drawn and calculated using the Kaplan-Meier method. The survival analysis was done using the Log-rank test. Univariate analysis and multivariate analysis were conducted using the COX regression model. Subgroup analysis was done using interaction test. Results:(1) The propensity score matching conditions and comparison of general data between the two groups of patients after matching: 198 of 311 patients had successful matching, including 99 in each group. Cases with tumor differentiated as poorly differentiation or well differentiation, cases with CA19-9 <27 U/mL or ≥27 U/mL, cases with CA125 <35 U/mL or ≥35 U/mL before propensity score matching were 109, 95, 156, 48, 186, 18 in the FOLFOX group, and 42, 65, 93, 14, 104, 3 in the FLOT group, respectively, showing significant differences in the above indicators between the two groups ( χ2=5.649, 4.798, 4.039, P<0.05). After propensity score matching, the above indicators were 44, 55, 85, 14, 96, 3 in the FOLFOX group, and 42, 57, 85, 14, 96, 3 in the FLOT group, respectively, showing no significant difference in the above indicators between the two groups ( χ2=0.082, 0.000, 0.000, P>0.05). (2) Follow-up: 198 patients of the two groups after matching were followed up for 2 to 69 months, with a median follow-up time of 38 months. During the follow-up, 92 cases survived without tumor, 2 cases underwent tumor recurrence or metastasis, and 104 cases died including 103 with tumor related death and 1 case with non-tumor related death. The courses of chemotherapy were 5.6±0.7 and 5.4±0.8 for the FOLFOX group and FLOT group, respectively, showing no significant difference between the two groups ( t=1.651, P>0.05). The 1, 3, and 5-year cumulative survival rates of patients were 72.2%, 31.5%, 27.7% and 83.2%, 42.8%, 38.2% for the FOLFOX group and FLOT group, respectively. The median overall survival time were 21 months and 34 months for the FOLFOX group and FLOT group, respectively, showing significant difference between the two groups ( χ2=4.473, P<0.05). (3) Analysis of survival factors: results of univariate analysis showed that cases undergoing chemotherapy with the FLOT regimen, cases with tumor as diffuse type of Lauren classification, cases with tumor as mixed type of Lauren classification, cases with tumor differentiated as well differentiation, cases with tumor diameter≥5 cm, cases with CA19-9≥27 U/mL, cases with carcinoembryonic antigen (CEA)≥3.4 μg/L, cases with tumor as T4 stage of T staging, cases with tumor as N2 stage of N staging, cases with tumor as N3 stage of N staging, cases undergoing distal gastrectomy and cases undergoing total gastrectomy were related factors influencing postoperative survival of patients ( hazard ratio=0.659, 1.617, 1.798, 0.672, 1.726, 1.655, 1.942, 2.036, 2.536, 4.085, 1.810, 2.310, 95% confidence interval: 0.444-0.978, 1.024-2.556, 1.105-2.926, 0.457-0.990, 1.159-2.569, 1.006-2.723, 1.295-2.912, 1.190-3.484, 1.409-4.564, 2.491-6.697, 1.020-3.211, 1.261-4.233, P<0.05). Results of multivariate analysis showed that cases undergoing chemotherapy with the FLOT regimen, cases with CEA≥3.4 μg/L, cases with tumor as N2 stage of N staging and cases with tumor as N3 stage of N staging were independent risk factors influencing postoperative survival of patients ( hazard ratio=0.622, 1.732, 2.217, 4.039, 95% confidence interval: 0.418-0.926, 1.124-2.670, 1.200-4.097, 2.448-6.662, P<0.05). (4) Subgroup analysis: results of subgroup analysis showed that of the different subgroups using gender, age, tumor Lauren classification, tumor differentiation degree, tumor location, tumor diameter, tumor markers, tumor T staging, tumor N staging and surgical procedures as subgrouping index, the efficacy difference between the FLOT group and the FOLFOX group was the same (interaction P>0.05). (5) Adverse reactions: the incidence of grade Ⅲ-Ⅳ adverse reactions of leukopenia, anemia, thrombocytopenia, nausea, vomiting and liver and kidney dysfunction were 11.1%(11/99), 2.0%(2/99), 3.0%(3/99), 12.1%(12/99), 4.0%(4/99), 1.0%(1/99) and 34.3%(34/99), 1.0%(1/99), 9.1%(9/99), 24.2%(24/99), 4.0%(4/99), 0 in the FOLFOX group and the FLOT group, respectively. There were significant differences of the incidence of leukopenia and nausea between the two groups ( χ2=15.213, 4.889, P<0.05). There was no significant difference of the incidence of thrombocytopenia between the two groups ( χ2=3.194, P>0.05) and there was no significant difference of the incidence of anemia, vomiting and liver and kidney dysfunction between the two groups ( P>0.05). There was no patient in the two group withdrawal from chemotherapy as no tolerance to toxic reactions. All patients were treated with glucocorticoids, proton pump inhibitors and serotonin receptor antagonists during chemotherapy. Patients undergoing leukopenia were treated with granulocyte stimulating factor. Conclusions:Compared with FOLFOX regimen, FLOT regimen which adds docetaxel significantly prolongs the postoperative median overall survival time of patients with advanced gastric cancer. However, FLOT regimen increases the incidence of grade Ⅲ-Ⅳ adverse reactions of leukopenia and nausea.
