Objective To investigate therapeutic effects of triple therapy combined Lansoprazole, clarithromycin and metronidazole for eradicating Helicobacter pylori-related ulcer. Methods Fivty-one patients with H. pylori-infected stomach ulcer or duodenal ulcer received the treatment of triple therapy regimen with lansoprazole, clarithromycin and metronidazole.the efficacy of ulcer healing and hp eradication were observed. Results the cure rate of the triple therapy was 90%,and the eradication rate of H. pylori was 88%.Conclusions Triple therapy using combined Lansoprazole, clarithromycin and metronidazole is worthy of clinical application for curing pylori - infected peptic ulcer accompanied by the lower does, the higher hp eradication rate, ulcer healing more rapidly and the shorter course of treatment.

Objective To evaluate the effect and security of ginkgo leaves associated with Perenan in the treatment of vascular dementia.Methods Eighty two cases of vascular dementia were randomly divided into ginkgo leaves associated with Perenan treatment group (observation group) and Piracetam treatment group (control group) by case-control study.Intelligence and the social function of all patients were evaluated separately by Mini Mental State Examination(MMSE)and Functional Assessment Questionnaire(FAQ)before medication and 6 months after medication.Results MMSE and FAQ score of the observation group was significantly higher than the control group(p<0.05),the efficiency rate was significantly improved (73.81% vs 47.50%).Conclusion Ginkgo praeparatum associated with Perenan can effectively improve the cognition and social function of vascular dementia patients.Moreover, it can postpone the development of Alzheimer's disease without obviously side effect.It's an effective and safe therapy method to select.

Objective To finally diagnose the outbreak of acute respiratory infection caused by Adenovirus 3 in students of the north of Jiangsu province by serologic study. Methods An enzyme-linked immunosorbent assay (ELISA) has been used to detect the adenovirus IgM in the serum of acute phase and the adenovirus IgG in the serum of recovery phase. A neutralization test has been used to detect the neutralization antibody in the serum of acute and recovery phase from cases and in the serum from the control. The SPSS11.0 has been applied to the statistical analysis of the data. Results The positive rate of IgM, IgG and recovery phase neutralization antibody of cases are 3.7%, 44.4% and 59.5% respectively, while those of control are 0%, 8.3% and 33.3% respectively, and the P values of Chi-Square are 0.510, 0.018 and 0.226 respectively. The neutralization test of paired serum of 6 in 9 cases showed that the antibody titers was obviously increased. The concordance between IgG detected by ELISA and neutralization antibody detected by neutralization test is 61.4% and the P value of Kappa is 0.070. Conclusion By the serologic study, we can finally diagnose that the outbreak of acute respiratory infection was caused by Adenovirus 3.

Objective To investigate the distribution and environmental pollution of dioxin-like polychlorinated biphenyls(PCBs) in a place of disused transformer and other electronic waste disassembled. Methods The ambient air, aerosol, water, soil and vegetable samples were collected to analyze the dioxin-like PCBs level with isotope internal standards and HRGC-HRMS techniques. Results The concentration of dioxin-like PCBs in ambient air was 4 031.77-4 942.34 pg/m3(namely 1.832-2.666 pg TEQ/m3), while in aerosol it was 325.45-3 499.77 pg/m3(0.370 9-1.536 3 pg TEQ/m3). In the soil sample, the value was 2 316.59-19 100.30 pg/g(1.358-15.264 pg TEQ/g) dry weight. In water it was 5.731-237.640 ng/L(2.585-73.046 pg TEQ/L). In vegetable it was 1 078.45-1 620.04 pg/g(0.778 3-1.126 2 pg TEQ/g) wet weight. In all air, aerosol, soil, water and vegetable samples, the content of PCB-118 was the most. PCB-126 had the highest TEQ value. In non-ortho PCBs, PCB-77 was of maximum content. In mono-ortho PCBs, PCB-118 was the most, and the followings were PCB-105, PCB-156 and PCB-167. All the 12 kinds of PCBs were investigated in all samples except PCB-169 absent in ambient air. Conclusions The investigated area around the disassembly of obsolete solid waste has been badly contaminated by dioxin-like polychlorinated biphenyls(PCBs), and PCBs already exist in the vegetables. According to the results of the present paper, some further studies should be carried out to evaluate the toxic effects on food and people health.

Embryonic stem cells detached from inner cell mass(ICM),can maintain self-renewal undifferentiation status and differentiate into almost every type of cells.Lots of genes take part in the regulation of embryonic stem cell's proliferation and differen-tiation.In this paper,we reviewed the related genes about embryonic stem cell's proliferation and differentiation,meantime draw off questions which need to be further illuminated.

Endogenous formaldehyde is generated in the human body.When the system of endogenous formaldehyde generation with scavengation is damaged,excess accumulation of endogenous formaldehyde induces vascular endothelial injury,atherosclerosis,myocardial damage and neurodegenerative diseases.Studies show that endogenous formaldehyde is one of the key factors during the process of cardiovascular and cerebrovascular diseases.Moreover,polyphenols are used as capture agents of endogenous formaldehyde to prevent and treat cardiovascular and cerebrovascular diseases.

Objective To explore the clinical outcome of individuals with Clinical High Risk (CHR) for psychosis and its relationship with Theory of Mind (ToM) function.Methods The Structured Interview for Prodromal Symptoms/Scale of Prodromal Syndromes (SIPS/SOPS) was applied to assess prodromal psychosis.The Reading the mind in the Eyes and faux pas Task were conducted to assess the function of Theory of Mind among the individuals of clinical high risk of psychosis.All participants had completed the 2-year follow-up.Conversion was determined using the criteria of presence of psychotic symptoms (POPS).According to the outcome,CHR individuals were divided into conversion group (n=20) and no-conversion group (n=50).The baseline clinical symptom characteristics and Theory of Mind were compared between groups.Results There was no significant difference in clinical symptom characteristics among individuals with CHR (P＞0.05).In the faux pas text,there were significant differences in Faux Pas Detection (P=0.01),Faux Pas Understanding (P=0.01) and Faux Pas Total (P=0.02) but not in control stories and the Reading the Mind in the Eyes Test between convertors and non-convertors (P＞0.05).Conclusion The ToM disability in clinical high risk population increases risk for conversion to psychosis.

Objective To establish a clinical test assay for detecting common respiratory viruses and enteroviruses (EV) by using mixed cultured Madin-Darby canine kidney cells (MDCK), human epidermoid cancer cells (Hep-2) and African green monkey kidney cells (Vero) to isolate common respiratory viruses and enteroviruses. Methods Throat swabs with influenza A and B viruses,adenovirus and EV71 were incubated with mixed cultured MDCK, Hep-2 and Vero in a single vial to observe the presence of cytopathic effects. Polymerase chain reaction (PCR), reverse transcription (RT)-PCR and monoclonal antibody-based immunofluorescene assay were also used for confirmatory test. Results The sensitive cell lines developed obvious cytopathic effects to the corresponding viruses, which were confirmed by the specific green particles observed by immunofluorescence assay and specific target PCR segments. Conclusions The shell-vial of mixed cells can simultaneously isolate different common respiratory viruses and EV. The isolated pathogens can be further confirmed by antigen test and PCR. This assay may improve the diagnosis of clinical viral diseases.

A total of 89 elderly patients with heart failure and preserved ejection fraction were randomly divided into 2 groups:patients in control group received conventional medication,those in exercise group receive conventional medication plus aerobic exercise training,which was lasted for 6 weeks.The changes in VO2max,maximum heart rate (HRmax),VO2max/HRmax,exercise time,6-minute walk and quality of life (QOL) were evaluated after 16 weeks.The VO2max,HRmax,VO2max/HRmax,exercise time,6-minute walk and QOL had increased significantly in exercise group,compared with the control group.The results indicate that aerobic exercise can improve cardiopulmonary function of elderly patients with heart failure and preserved ejection fraction.
