Objective To investigate the expression of forkhead box protein P1(FOXP1)in gastric mucosa-associated lymphoid tissue(MALT)lymphomas and its relationship with histological morphology and prognosis. Methods In this study.samples of 43 MALT lymphoma were studied histologically and divided into monomorphic histology group and polymorphic histology group according to their cellular features.The expressions of FOXP1 and NF-κB in gastric MALT lymphoma were evaluated immunohistochemically by two-step method of Envision,and the clinicopathological features and prognosis were analyzed retrospectively.Results The nuclear expressions of FOXP1 in 43 cases with gastric MALT lymphoma were 44%(19 of 43),including strong immunoreactivity in 7 cases and moderate immunoreactivity in 12 cases.There were 4 cases with positive immunoreactivity in moninorphic histology group and 15 cases in polymorphie histology group,and the difference was statistically significant(15%vs.88%,P＜0.01).All the postoperative recurrent cases were strongly positive with FOXP1 stain,and it was closely with FOXP1 expression(P＜0.01).The median survival time(26 months)in polymorphic histology group was significantly shorter than that(123 months)in monmorphic histology group(P＜0.01),and the median survival time was significantly longer in negative FOXP1 expression group than that in moderate FOXP1 expression group and in strong FOXP1 expression group(115 vs.55 vs.12 months)(P＜0.05).similarly,the median survival time in nuclear factor kappa B(NF-κB)expression group was significantly shorter than that in negative NF-κB expression group(26 vs.131 months)(P＜0.01).The median survival time in stageⅠ(98 months)and stage Ⅱ(121 months)was significantly longer than that in stage Ⅱ E+Ⅳ(33 months)(P＜0.01).By multivariate COX regression analysis.FOXP1 nuclear expression and clinical stage were independently prognostic factom. Conclusion FOXP1 expression may be used as a biomarker for the assessment of malignant transformation to diffuse large B-cell lymphoma(DLBCL)and predicting prognosis.

Objective To study the efficacy and safety of sedation in gastroscopy with a combined use of rimifentani and propofol compared to a control,non-sedative group.Methods 120 cases in sedative group were given intravenous rimifentani and propofol.Patients'feeling and discomfort,operator's satisfaction and operative duration were compared with the controI group(n=120,without sedation).The changes of blood pressure,heat rate and blood oxygen saturation were recorded and analysed.Results 118 patients(98.3%)in sedative group and 0 patient(0)in control group did not complain any discomfort and pain duing gastroscopy(P＜0.01).The incidence of cough,restlessness,nausea and vomiting,and guttural discomfort in sedative group(1.7%,3.3%,1.7%,and 0,respectively)was lower as compared with the control group(9.2%,26.7%,48.3%and 100%,respectively,P＜0.01).The blood pressure in sedative group was decreased duing the procedure and recovered after the procedure.Conclusion With intravenous use of rimifentani and propofol,gastroscopy can be performed effectively and safely.

AIM: To investigate the protective mechanism of extract of Ginkgo biloba (EGB) on apoptosis of hippocampus neuronal cells in type 1 diabetic encephalopathic rats. METHODS: Thirty-six male Sprague-Dauley rats were divided into 3 groups: control group, diabetic group and EGB-treated group. Streptozotocin was injected intraperitoneally to the animals in later two groups to induce diabetes. The rats in EGB-treated group were injected intraperitoneally with EGB, and the same volume of normal saline was injected to the rats in other groups. At the end of the 12th week, the spatial learning and memory abilities of rats in each group were examined by Morris water maze test. Blood glucose and serum insulin concentration were measured. The neuron densities in hippocampus were measured by Image-Pro Plus 6.0 software. The expressions of Bax, Bcl-2, caspase-3 were assayed by Western blotting and immunohistochemistry. RESULTS: Compared to control group, the level of blood glucose (P<0.01), the protein expression of Bax (P<0.01) and caspase-3 (P<0.01) in hippocampus neuronal cells, and the ratio of Bax/Bcl-2 (P<0.01) and the escape latency (P<0.01) in diabetic group, were significantly increased, while the serum insulin concentration (P<0.01), the neuronal density (P<0.05) in CA1,CA2 hippocampal regions and the platform searching score (P<0.01) were significantly deceased. After treated with EGB, the serum insulin concentration (P<0.05), the neuronal density (P<0.05) in CA1,CA2 hippocampal regions and the platform searching score (P<0.01) were significantly increased, while the level of blood glucose (P<0.01), the protein expression of Bax (P<0.05), caspase-3 (P<0.05) in hippocampus neuronal cells, the ratio of Bax/Bcl-2 (P<0.01) and the escape latency (P<0.05) were significantly deceased than those in diabetic group. The protein expression of Bcl-2 in hippocampus neuronal cells did not alter in any experimental rats. CONCLUSION: EGB improves the spatial learning and memory capacity in diabetic rats by decreasing the expression of Bax, Bax/Bcl-2 ratio and down-regulating caspase-3 to reduce neurocyte apoptosis and increase the neuron density in CA1, CA2 hippocampal regions, suggesting that effective regulation of neuron apoptosis associated genes may be one of the mechanisms for EGB to treat diabetic encephalopathy.

Objective: To improve clinical utility of the Nurses Observation Sca le for Inpatient Evaluation (NOSIE-30) in China. Methods: Based on the original scale, which only provides names and ranked scores for items, we developed clear definitions for each item and anchoring descriptions for score rating. 164 firs t-episode schizophrenic patients were evaluated with this scale every two weeks after admission. A total of 994 evaluations were completed. The collected data w ere randomly divided into two independent data sets. The number and content of t he subscales were revised based on principal component factor analysis and item analysis of the first data set. The revised scale was then evaluated and compare d with the original 7-subscale version of the instrument using the second data s et. Results: Factor analysis found that the factor structu re of the revised scal e was markedly different from that of the original instrument. Item analysis res ulted in elimination of 30 original items and redistribution of the remaining 26 items into 5 subscales. Comparison of the revised scale with the original instr ument revealed better psychometric properties for the former than the latter.Conclusion: The subscale scores of the original 7-subscale v ersion of NOSIE-30 did not reflect independent symptom clusters in Chinese schizophrenic inpatients. T o improve the usefulness of the scale in China, the present study recommended a better revised scale with re-definition of items into 5 subscales.

Objective To express and purify recombinant human platelet glycoprotein Ⅵ extracellular domain and prepare the polyclonal antibody against it.Methods Human platelet glycoprotein Ⅵ extracellular domain fragment (123~268 residues) was amplified by polymerase chain reaction and cloned into the prokaryotic expression vector pGEX-3x.The recombinant plasmid was constructed and expressed in E.coli after induction with isopropyl-?-D-thiogalactopyranoside (IPTG).The fusion protein was identified by Western blot analysis after purification by affinity chromatography.Rabbits were immunized with the purified fusion protein, and the collected rabbit antiserum was evaluated by sandwich ELISA, Western blot and flow cytometry.Results The coding sequence of GPVI extracellular domain was successfully inserted into pGEX-3x.Sequencing result showed that the cloned gene was identical as reported.After induction, a Mr 42kd fusion protein was expressed and confirmed by Western blot, which was identical to that expected.The titers of the antisera were up to 1∶[KG-*2]128. Sandwich ELISA result demonstrated that the prepared antibody recognized GPVI in human platelet. Western blot and flow cytometry revealed that the prepared antibody reacted with GPVI of platelet lysate and the native GPVI on human platelet surface.Conclusions Using purified prokaryotic expressed the fusion protein as antigen, the specific antibody was elicited in the immunized animals. The prepared polyclonal antibodies react specially with GPVI on human platelet surface and can be used for further studies of GPVI.

Objective To analyze the antimicrobial resistance profile of clinical isolates in Shanghai Xinhua Hospital Chongming Branch affiliated to Shanghai Jiaotong University School of Medicine , a member of China Antimicrobial Resistance Surveillance System, during 2015, for the purpose to facilitate rational antimicrobial therapy. Methods Strain identification?and?susceptibility?testing?were?carried?out?for?the?clinical?isolates?using?MicroScan?WalkAway?96?Automated?Systems and Kirby-Bauer method. Results In 2015, a total of 1815 isolates were collected, including gram-negative bacteria (73.2 %) and gram-positive bacteria (26.8 %). The top three frequently isolated species were Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa. ESBL-producing strains were found in 36.3 % of the Escherichia coli isolates, 12.6 % of the Klebsiella (K. pneumoniae and K. oxytoca) isolates, and 28.0 % of the Proteus mirabilis isolates. The prevalence of carbapenem-resistant strains was 0.69 % in Enterobacteriaceae isolates. The prevalence of methicillin-resistant strain was 29.1 % in S. aureus, and 61.4 % in coagulase-negative Staphylococcus isolates. No more than 15 % of the Enterobacteriaceae isolates and no more than 20 % of the P. aeruginosa and Acinetobacter isolates were resistant to carbapenems. No vancomycin-or linezolid-resistant strains were found in Enterococcus or Staphylococcus. Conclusions Antibiotic-resistant clinical isolates are a serious threat for clinical antimicrobial treatment. We should pay more attention to such urgent situation and rational use of antibiotics.
