Objective To investigate three strains of vaginal Lactobacillus for their regulative effects on macrophage and murine uterocervical carcinoma number 14(U14).Methods Mice were transplanted with U14,then ramdomly divided them into 5 groups.Model group and DDP group respectively were regarded as nagative and positive comparison;Lactobacillus groups were injected with 1010 each with Lactobacillus into peritoneum for 10 days successively.The TNF-? and NO content secreted by KM mice and the inhibitory rate of U14 cells were detected.Results The production of TNF-? and NO secreted by the peritoneal macrophages activated by Lactobacillus was greatly increased.The three strains of Lactobacillus all had significantly antitumor effects on KM mice bearing U14.Conclusion Lactobacillus showed a marked inhibition effects on the U14 cells and can activate macrophages to produce TNF-?and NO which may be involved in the antitumor mechanism.

Objective To study the effects of ?-asarone on mitochondrial membrane potential(MMP) of cardiac myocytes with ischemia reperfusion injury. Methods The cardiac myocytes model of myocardial ischemia reperfusion injury (MIRI) was induced with sodium dithionite (Na2S2O4). The primary cultured cardiac myocytes of SD neonatal rats were randomized into six groups:normal group,model control group,high-dose ?-asarone (25 ?g/mL),middle-dose ?-asarone group(12.5 ?g/mL),low-dose ?-asarone group (6.25 ?g/mL) and medium group. Mitochondrial membrane potential(MMP) of myocardial cells were measured by flow cytometry. Results Compared with the normal group,MMP in the model control group was obviously decreased(P

Objective To study the protective effects of ?-asarone against the myocardial ischemia/ reperfusion injury (MI/RI) in cultured cardiac myocytes. Methods MI/RI model was set up with Na2S2O4, which make use of rat cardiac myocytes. The viability of cardiac myocytes (using MTT method), dehydrogenase (LDH, CK) activitices in the medium were measured. Results In MI/RI model, ?-asarone can obviously advance the viability of cardiac myocytes, and decrease the dehydrogenase (LDH, CK) activitices in the medium. Conclusion ?-asarone showed protective effects against the myocardial ischemia/reperfusion injury in cultured cardiac myocytes.

Objective To Study on anti-thrombosis effect of volatile oil of Acorus Tatarinowii Schott(AST) and ?-asarone.Methods Thrombosis test,blood hyperviscocity test,blood clottingtest,and in vitro fibrinolytic test were carried out to investigate the effects of volatile oil of AST and ?-asarone on the following indexes:weight of thrombus,prothrombin time(PT),activated part prothrombin time(APTT),hemorheology,clotting time,the weight of plasma fibrin clot.Results Volatile oil of AST and ?-asarone can lower the weight of venout thrombosis in rats,and prolong PT and APTT of blood plasma in rats.They can improve hemorheology in the hyperviscocity rats,especially reduce viscosity of whole blood and blood plasma obviously.They can prolong the clotting time in mice obviously;and decrease the weight of plasma fibrin clot.Conclusion Volatile oil of SCP and ?-asarone has anti-thrombosis anticoagulationand fibrinolyitc effect,and its mechanism may be related to the prolongation of PT and APTT,improving blood viscosity.

Objective: To investigate the association between three single nucleotide polymorphisms-2562G＞A,-416C＞G and-232G＞A in Tim-3(T cell immunoglobulin domain and mucin domain protein 3)gene promoter region and child allergic asthma in Chinese Han population by using family-based association study.Methods: Genotypes of 3 SNPs(-2562G＞A,-416C＞G and-232G＞A)in 118 allergic asthma nuclear pedigrees were analyzed by restriction fragment length polymorphism.The genotype data were analyzed by using the family-based transmission disequilibrium test(TDT).Haplotypes and their frequencies were established and analyzed by TRANSMIT software.Results: ①No transmission disequilibrium was found at the-2562G＞A and-232G＞A sites from heterozygous parents onto patients in 118 trios analyzed by TDT(P＞0.05);However,at the-416 C＞G locus,the observed values of G allele from heterozygous parents to offspring were significantly higher than the expected values(P＜0.05)②The haplotype TDT analysis by TRANSMIT showed the observed and the expected value in GCA and GGA haplotype from parents to the affected offsprings had significant difference respectively(P＜0.05).The Global X~2 test results also showed that Tim-1 haplotype were associated with child allergic asthma(X~2 = 17.26, P＜0.01).Conclusion: Tim-1 gene promoter-416C＞G locus are associated with allergic asthma susceptibility in Hubei Chinese Han population and the haplotypes constructed by-416C＞G are also associated with asthma.Tim-1 genetic polymorphism may play an important role in the pathogenesis of asthma.
