1.Correlation between aluminum overload-induced brain neurodegeneration and monoamine oxidase B in mouse brain
Journal of Chongqing Medical University 1986;0(02):-
Objective:To adopt the brain lesion model of mouse induced by overload aluminum to study the relationship between monoamine oxidase B disorder and neurodegeneration induced by overload aluminum(Al).Method:Aluminum overload models were established by injection of 3?l AlCl3 into lateral ventricle of miceeach day for 5d.The AlCl3 solutions injected in different modelswere with different concentrations and they were 0.125%,0.25%,0.5%.On d10,d20,and d30 after the final administration of AlCl3 solution,the learning and memory function of mice,pathomorphology of hippocampi,and MAO-B activity were determined.Results:Aluminum overload elevated MAO-B activity,caused karyopyknosis and loss of neurons in CA1 area of hippocampi,in dose-and time-dependent manners.Conclusion:The results indicate that neurodegeneration induced by Al toxicity may be related to the monoamine oxidase B homeostasis interfered by Al overload.

Objective To investigate clinical characters of functional dyspepsia (FD) and organic dyspepsia (OD) and evaluate the Chinese management guideline of dyspepsia. Methods Three hundreds patients with epigastric dyspepsia symptoms received a series of examinations including a detailed investigation of symptoms, liver functions, upper gastrointestinal endoscopy and B ultrasound, and then they were divided into OD and FD groups in accordance with Rome Ⅱ criteria. Results 153 (51.0%) and 147 cases (49.0%) were ascribed to FD and OD respectively. FD occurred more often at the age of less than 40 ( P =0.006). The scores of such symptoms as bloating( P

5.On defects of drug and its law responsibility
Chinese Journal of Medical Education Research 2003;0(04):-
Object to define defects of drug accurately and to initially discuss its law responsibility. Method With comparative study and system thinking,we acquired few scientific recognition of drug’s defects. Result & Conclusion Defects of drug are not equal to negative drug reaction. The former one should be an unreasonable and potential risk which induces no expectant therapeutic efficacy to provide. And its law responsibility could be no-fault liability accompanied by state compensation.

Objective To construct the immune genes expression profile database of multiple sclerosis (MS) and to screen the high immune related candidate genes by using microarray analysis Methods Polymerase chain reaction (PCR) products on behalf of 484 immune related genes from mixed tissue library were assembled on the modified Oako glass slide The general RNA from MS patients and normal persons lymphocytes was transcripted to cDNA by RT PCR and labelled with cy 3 and cy 5 The two probes were mixed and hybridized with the above mentioned gene chips Scan array 4000 was used for scanning the hybridizing signals and GenePix Pro3 0 for date analysis Results Of the total 484 double genes monitored,22 genes of group one showed changes in expression level of the ratio outside 0 5 and 2.0;27 genes differ in group 2;72 genes change in group 3 With the same consistent gene ID of the double genes, the group one was 6,the group tow was 9 and the group three was 30 Conclusions These results show that the different expression of immune related genes might occur between MS patients and normal persons It might also afford a view of the changes that these genes should be probably related to the occurrence, development or progress of MS The cell immune related genes might be the important and most immune related genes involved in MS pathogenesis The results suggest the deeper insights into the mechanism,relapsing and treatment of MS

Objective To investigate the efficacy of ultrasound guided injection of embryonic inactivation in the treatment of ectopic pregnancy.Methods Eighty cases of ectopic pregnancy were selected in the Second Hospital Affiliated to Fujian Medical College from June 2011 to June 2014, in accordance with the order of admission, they were divided into two group of each 40 cases.The control group carries on the conservative treatment, intramuscular injection of methotrexate (MTX) , while the observation group in transvaginal ultrasonography guided implantation of MTX.The curative effect of two groups was Compared.Results The observation group effective rate of the treatment was 92.5% (37/40), significantly higher than that of control group(62.5% (25/40) ,x2=10.32 ,P<0.01).The patients of two groups with no due mass rupture and transit operation.The observation group mass less than or equal to 2 cm disappear time required was (15.4±2.6) d,significantly shorter in the control group((27.1±3)d,t=18.64,P<0.01).Serum β-human chorionic gonadotropin decreased to normal time required was (13.7±6.1)d, significantly lower than that of the control group((18.4±7.2) d,t=3.15 ,P<0.01).The adverse reaction rate in the observation group was 10% (4/40), significantly lower than that of the control group (32.5% (13/40), P =0.028).Conclusion Ultrasound guided injection of embryonic inactivation treatment for ectopic pregnancy have curative effect, can effectively improve the clinical symptoms and reduce adverse reaction.

OBJECTIVE:To investigate the inhibition effect of berberine on colon carcinoma lovo cell. METHODS:Colon car-cinoma lovo cells were cultured and treated with berberine and meloxicam in various concentrations. At 6 h,12 h and 24 h after treatment,the proliferation of lovo cell was assayed by MTT method. RT-PCR method and Western blot testing were used to eval-uate the mRNA and protein expressions of COX-2 in lovo cell. RESULTS:Berberine with concentration larger than 10-5 mol?L-1 and meloxicam with concentration larger than 10-4 mol?L-1 could inhibit the growth and proliferation of lovo cell and showed concentration and time dependent manners(P
