AIM: To study the protective effect of hepatic stimulator substance(HSS) on chemotherapeutic liver damage induced by cyclophosphamide and its possible mechanism.METHODS: The serum biochemical parameters,oxidative parameters and anti-oxidative parameters of liver tissue of male Kunming mice inoculated with S_(180) cells were measured.The pathology of the liver was observed with microscope.The weight of S_(180) sarcom was weighted.RESULTS: The elevation of MDA content of liver tissue and the less of GSH content and CAT,GSH-PX,GST,and SOD activities induced by CP were restored remarkably by HSS.The ALT and LDH activities of serum in HSS group which was compared with control group and CP group were not statistically distinctive.In the pathologic examination,spotty and focal necroses of hepatocytes in the liver of CP group were found with a great deal of inflammatory cells infiltration in the necrotic and portal areas,while the damage in the liver of HSS group was ameliorated obviously;The weight of S_(180) sarcom in CP group and HSS group was not statistically distinctive.CONCLUSION: The effect of HSS on CP-induced chemotherapeutic liver damage maybe due to anti-oxidative activity.

Objective To survey the knowledge of chronic stable coronary artery disease management among general practitioners (GPs) in Shanghai Pudong New Area.Methods The survey was conducted among 363 GPs with at least 2-year work experiences from community health service centers in Shanghai Pudong New Area from July to September in 2014.A self-designed questionnaire based on the guidelines/consensus of chronic stable coronary artery disease management were used in the survey.The questionnaire consisted of 4 parts:diagnosis,drug therapy,revascularization and treatment of special types.Results Among 363 participants 362 questionnaires were completed.History taking,physical examination and electrocardiogram were applied for diagnosis in all participants,49.2％ (178/362) also used coronary computed tomography angiography,26.5％ (96/362)used exercise testing for assistant examination.More than 95.0％ of participants recognized that smoking,obesity,hyperlipidemia,hypertension,diabetes were risk factors.75.7％ (274/362) of participants used aspirin,91.4％ (331/362) knew the dose of aspirin as 75-150 mg;for aspirin intolerance 14.6％ (53/362)would use clopidogrel alternatively.50.6％ (183/ 362) of participants sometimes used statins;and 39.2％ (142/362) did not use stain because of not knowing the contraindication.Facing increases of alanine aminotransferase or aspartate aminotransferase levels 95.3％ (345/362) of participants would immediately discontinue stain;80.4％ (291/362) discontinued statins as creatine kinase increased.32.0％ (116/362) of participants gave enough drug-free period avoiding nitrates resistance.79.6％ (288/362) seldom used β-blockers and 42.5％ (154/362) failed to use β-blockers because not knowing the contraindication.78.7％ (285/362) knew percutaneous coronary intervention but did not know its indications;83.1％ (301/362)knew coronary artery bypass but did not know its indications.27.6％ (100/362) knew calcium antagonists were first-line drugs for variant angina and 93.6％ (339/362) never heard of microvascular angina.Conclusion The survey shows that GPs from community health service centers in Shanghai Pudong are not well familiar with examination of coronary heart disease and lack of sufficient knowledge of drugs recommended by the guideline,not well understand the indications for revascularization and the diagnosis and treatment of special types of coronary heart disease.

Objective To evaluate the association between cytomegalovirus (HCMV) infection and atherosclerosis (AS) and explore the possible role of endothelin (ET) and serum tumor necrosis factor(TNF ?) in the pathogenesis of AS in diabetic patients and the relationship between HCMV infection and concentrations of ET and TNF ?. Methods Blood samples were collected from 21 patients with AS of type 2 DM, 47 patients with non AS of type 2 DM and 20 controls. Special antibodies to HCMV (IgM,IgG) were measured by enzyme linked immunosorbent assay (ELISA) . The concentrations of serum TNF ? and plasma ET were determined by RIA. Results (1) Type 2 diabetic patients, especially those with established AS, had a higher prevalence of active infection of HCMV. (2) The levels of plasma ET and serum TNF ? in type 2 diabetic patients were higher than those in normal people. In the pathogenesis of AS in diabetic patients, the ET played more important role than the TNF ?.(3) There was a significantly positive correlation between anti IgM to HCMV and the level of plasma ET in type 2 DM patients. It suggested that the injury of endothelium cell was related to the active infection of HCMV. Conclusion The study suggests that HCMV infection may be important in the pathogenesis of AS in type 2 diabetic patients and ET possibly plays an important role on the pathological course of AS.

The gene and the amino acid sequence of the structural and regulatory region of the Pseudomonas aeruginosa with different resistance patterns were analyzed. Six strains with different resistance patterns were selected and the AmpC beta-lactamase was identified. The objective gene fragment was amplified by colonies PCR. The sequences of the PCR-products were analyzed. The DNA sequence of the structural gene ampC and the regulatory genes ampR, ampD and ampE was detected. The 6 strains and the wild-type Pseudomonas aeruginosa are highly homogeneous in structural and regulatory region. Some new mutant points were found.

ObjectiveTo investigate the effects of early stage Alzheimer's disease(AD)on white matter(WM)integrity using diffusion tensor imaging(DTI)and its relationship with cognitive function decline.MethodsDTI was performed in 32 subjects,including 14 early AD patients and 18 elder controls(ON)with a 1.5 T MR scanner. Fractional anisotropy(FA)and mean diffusivity(-D)values were computed and compared for 9 regions of interest(ROI).Eight standard neuropsychological tests were performed and compared between AD and ON to evaluate basic cognitive capacities of AD.Correlation analysis was applied between FA,(-D) values and scores of neuropsychological tests for all subjects.ResultsFA significantly decreased in splenium of the corpus callosum and the posterior parietal-temporal region(S2),and D significantly increased in the splenium in AD patients(P＜0.05).AD patients showed lower scores compared with ON in all neuropsychological tests(P＜0.05).FA of the splenium and S2 positively correlated with several tests scores,while (-D) of multiple ROIs negatively correlated with several tests scores (P＜0.05).ConclusionsIn the early stage of AD,neuropathology has effect not only on cognitive function,but also on white matter structure,and they have strong relationship.AD patients show white matter changes in specific regions,which reflect loss in cortico-cortical connections.

Objective: To study the effect of Maitork (a sodium chloride injection containing Ginkgo bioba extract and ligustrazine phosphate) on plasma levels of fibrinogen (Fg), platelet granule membrane protein 140 (GMP-140), tissue plasminogen activator (tPA) after focal cerebral ischemia-reperfusion in rats. Methods: Eighty male SD rats were randomly allocated into groups 3-day (n=40) and 7-day (n=40) after operation. Then each group was divided into 4 subgroups: sham-operation, ischemia control, Ginaton and Maitork. The focal cerebral ischemia model was established in rats. The activities of GMP-140 and tPA were measured by chromogenic substrate assay, and the level of Fg was measured by gel plaque assay. Results: The level of Fg in the Ginaton group was significantly higher than that in the ischemia control group, and the 7-day group was also significantly higher than that in the Maitork group (P

OBJECTIVE: To analyze 113 patients with drug-induced liver disease(DILD) so as to clinically validate the international generally-accepted diagnostic criteria.METHODS: 113 DILD cases were reviewed and categorized according to international generally-accepted diagnostic criteria and then graded separately by Maria clinical scale and DDW-J scale to analyze the correlations.RESULTS: 113 out of 822 patients with liver diseases were DILD(13.7%),among whom 17 were of hepatocellular type(15.0%),92 cholestasis type(81.5%) and 4 mixed type(3.5%).Application of Maria clinical scale and DDW-J scale led to different number of DILD cases diagnosed.DILD were mostly induced by antihyperlipidemic drugs and immunosuppressants followed by anticoagulant drugs.CONCLUSION: DDW-J scale,which is more close to clinical diagnostic criteria,contributed to the standardization of the diagnostic criteria of DILD,yet it has its limitations as well.
