Objective To investigate effect of serum apoptosis factor and long-term effect on medical abortion patients by sequential misoprostol. Methods 80 cases of early pregnancy patients who required termination pregnancy, were selected and randomly divided into 2 groups.40 cases in control group were treated with mifepristone 25mg oral, misoprostol 600μg, 4 times a day.40 cases in experiment group were treated with sequential use of misoprostol.Effect of medical abortion, survivin and caspase-3 were compared after 7d treatment.Gynecological inflammation, dysmenorrhea and infertility were compared for 2 years.Results Compared with control group, complete abortion rate of the experiment group was higher (P<0.05).The incidence of adverse drug reactions of the experiment group was lower than control group (P<0.05) after 2 years follow.up.Compared with the control group, HCG,E3 and P of experimental group were lower (P<0.05).After 7 days of medication,survivin decreased,caspase-3 increased,compared with control group, survivin of the experiment group was lower, caspase-3 was higher ( P<0.05 ) .Conclusion Misoprostol sequential can improve the success rate of medical abortion abortion, reduce the complications of abortion, presumably with the inhibition of survivin expression, is associated up regulation of caspase-3 levels.

Objective To compare the effect of TNF-α preconditioning and ischemic preconditioning on hepatic ischemia-reperfusion injury ( IRI) and investigate the underlying mechanisms of TNF-αpreconditioning. Methods Fourty healthy male Wistar rats were random-ly divided into four groups which were Sham-operated group ( SO) ,ischemia-reperfusion group ( IR group:produced by total inflow occlusion for 30 min) ,ischemic preconditioning group ( IPC group:induce with 10 min hepatic ischemic and open 10 min before IR) and TNF-αpre-conditioning group ( TPC group:intraperitoneal injection with 1 μg/kg TNF-a 30 min prior to IR) . The sample of blood and hepatic tissue of all groups were taken after experiment. The protein levels of NF-κBp65 and Bcl-2 in the hepatic tissue were detected by immunohistochemis-try. Results There was significant difference (P<0. 05) between IR group and IPC group,TPC group on the level of ALT,AST and the expression of NF-κBp65 and Bcl-2,apoptosis index in hepatic tissue. There was no significance difference (P>0. 05) between IPC group and TPC group. Conclusion TNF-α preconditioning decreased the intensity of hepatic IRI,just as ischemic preconditioning,by induces an de-crease in the NF-κBp65 expression and an increase in the Bcl-2 expression.

During the process of building TCM effect evaluation on coronary heart disease (CHD), with the defined connotation and extension of heart diseases , except the consideration on its clinical symptoms , TCM four diagnosis and various current modern cardiovascular disease diagnostic methods should be organically com-bined according to the original macro basis . The micro quantitative evaluation is given on therapeutic effect of disease treatment in order to construct the complete TCM effect evaluation system.

OBJECTIVETo investigate the changes in the quantity of colonizing Streptococcus mutans(S. mutans) and Actinomyces on the root surface plaque before and after post-core crown restoration of the mandibular first molars in the elderly patients.

METHODSA total of 30 elderly patients, each with one post-core crown restoration of the mandibular first molar, were randomly chosen to participate in the studies. Patients with mandibular first molars with post-core crown restoration and those with healthy contralateral mandibular first molars were divided into the test and control groups, respectively. Root surface plaques of the two groups were collected before tooth preparation, 72 h after preparation, one week after preparation, and one month after restoration. S. mutans, Actinomyces naeslundii (A. naeslundii) and Actinomyces viscosus (A. viscosus), were identified using colony morphology, biochemical techniques, and polymerase chain reaction (PCR). Plaque count was measured using microbial colony count.

RESULTSThe number of S. mutans and A. viscosus and A. naeslundii in the test group, which was statistically significant (P<0.05), increased 72 h after preparation. The quantities of S. mutans, A. viscosus, and A. naeslundii one week after preparation were significantly different (P<0.05). The plaque count of S. mutans, A. viscosus, and A. naeslundii in the test group decreased one month after restoration (P<0.05).

CONCLUSIONThe quantities of S. mutans, A. viscosus and A. naeslundii increase one week after preparation but decrease one month after restoration. The finding suggests that dentists should educate patients about plaque control during the early period after tooth preparation.

Conclusion The treatment thinking of Professor ZENG Bin-fang for CHB pays attention to entire concept, attaches importance to Zang-fu transmission, regards“nourishing liver, soothing liver and strengthening spleen”as the therapeutic principle, together with nourishing yin, softening and resolving hard mass, clearing heat-toxin and eliminating dampness.

The metabolic characteristics of ligustrazin (TMPz) in liver microsomes were investigated in the present study. The reaction phenotyping of TMPz metabolism was also identified by in vitro assessment using recombinant human cytochrome P450 enzymes (CYP) and UDP glucuronosyltransferases (UGT). TMPz was incubated at 37 degrees C with human (HLM) and rat liver microsomes (RLM) in the presence of different co-factors. The metabolic stability and enzyme kinetics of TMPz were studied by determining its remaining concentrations with a LC-MS/MS method. TMPz was only metabolically eliminated in the microsomes with NADPH or NADPH+UDPGA. In the HLM and RLM with NADPH+UDPGA, t1/2, K(m) and V(max) of TMPz were 94.24 +/- 4.53 and 105.07 +/- 9.44 min, 22.74 +/- 1.89 and 33.09 +/- 2.74 micromol x L(-1), 253.50 +/- 10.06 and 190.40 +/- 8.35 nmol x min(-1) x mg(-1) (protein), respectively. TMPz showed a slightly higher metabolic rate in HLM than that in RLM. Its primary oxidative metabolites, 2-hydroxymethyl-3, 5, 6-trimethylpyrazine (HTMP), could undergo glucuronide conjugation. The CYP reaction phenotyping of TMPz metabolism was identified using a panel of recombinant CYP isoforms (rCYP) and specific CYP inhibitors in HLM. CYP1A2, 2C9 and 3A4 were found to be the major CYP isoforms involved in TMPz metabolism. Their individual contributions were assessed b) using the method of the total normalized rate to be 19.32%, 27.79% and 52.90%, respectively. It was observed that these CYP isoforms mediated the formation of HTMP in rCYP incubation. The UGT reaction phenotyping of HTMP glucuronidation was also investigated preliminarily by using a panel of 6 UGT isoforms (rUGT). UGT1A1, 1A4 and 1A6 were the predominant isoforms mediated the HTMP glucuronidation. The results above indicate that the metabolism of TMPz involves multiple enzymes mediated phase I and phase II reactions.
