OBJECTIVE:To study the role of clinical pharmacists in the utilization of antibacterial drugs in gynecologic inpatients. METHODS: Gynecologic inpatients in our hospital from Jun. to Dec. in 2008 were randomly divided into clinical pharmacists participation group(pharmacists group, n=158) and doctors’ experience group (experience group, n=158) according to admission order. The utilization of antibiotics during hospitalization was analyzed statistically. RESULTS: Two groups were all treated with antibacterial drugs. The utilization rate of single drug in pharmacist group was significantly higher than in experience group while the utilization rates of two-drug and three-drug combination in pharmacist group were strikingly lower than in experience group (P

Objective:To investigate the value of serum CD105, CA125 and CA724 levels in the treatment of cervical cancer with paclitaxel and cisplatin.Methods: A total of 42 patients with cervical cancer were randomly divided into observation group (n=21) and control group (n=21). The observation group was given intravenous infusion of paclitaxel 135 mg/m2, and intravenous infusion of cisplatin 60 mg/m2 after 3 hours. The control group was given only intravenous infusion of cisplatin, during the hydration and antiemetic drugs. They need 2 courses of chemotherapy, with each chemotherapy interval of 21 days. The levels of serum CD105, CA125 and CA724 before and after treatment were compared and analyzed.Results: The levels of CD105, CA125 and CA724 in the observation group were lower than those in the control group (t=19.119,t=22.493,t=15.46;P<0.05). There was a negative correlation between CD105, CA125 and CA724 levels and clinical efficacy (rs=-0.427,rs=-0.335,rs=-0.408;P<0.05).Conclusion: Paclitaxel combine with cisplatin in the treatment of cervical cancer has better clinical curative effect, and the mechanism is related to lower CD105, CA125 and CA724 levels.

Objective:To explore the role of CD86 costimulation in inducing Th2 bias at maternal-fetal interface and the relationship to outcomes of gestation.Methods:Pregnant DBA/2J mated CBA/J mice with a high embryo resorption rate from 20% to 30% and BALB/C mated CBA/J mice with low embryo resorption rates were studied,with rat anti-murine CD86 mAb administered intraperitoneally at the dosage of 100 ?g,at the time of implantation(day 4) and on the following days(6,8,10) of gestation.The competitive semiquantity RT-PCR and ELISA was applied to analysis of the transcription and expression of Th type-1/Th type-2 cytokines at the maternal-fetal interface at day 9 or day 14 of gestation respectively.The embryo resorption rate was counted at day 14 of gestation.Results:In the model of normal pregnancy,blockade of CD86 costimulation had no significant effects on the original Th2 bias at the maternal-fetal interface,and the outcomes of gestation had not changed significantly.While in the model of abortion-prone,blockade of CD86 costimulation successfully induced a Th2 bias at maternal-fetal interface.Therefore,the embryo resorbing rates decreased significantly.Conclusion:Blocking the CD86 costimulation at the early stage of the abortion-prone pregnancy could recover the physiological balance of Th1/Th2 at maternal-fetal interface and induce the maternal-fetal immune tolerance.

Objective:To study the effect of sufentanil combined with dezocine on the PCIA after abdominal operation. Methods:Totally 110 patients undergoing abdominal operation were randomly divided into the experimental group and the control group with 55 cases in each. The two groups were both treated with electronic analgesia pump for the PCIA after the operation. The control group was given dezocine 0. 3 mg·kg-1 ,and the experimental group was given sufentanil injections 0. 1 g·kg-1 plus dezocine 0. 3 mg·kg-1 . The VAS score,adverse drug reactions,Ramesay scores,press number of patient controlled analgesia,exhaust time,recovery time of bowel sounds and bowel audio rate index in the two groups were compared to evaluate the effect of PCIA. Results:All the observed in-dices in the experimental group were significantly better than those in the control group(P<0. 01). The incidence of adverse reactions in the experimental group was significantly higher than that in the control group(P<0. 01). Conclusion:Sufentanil combined with dezocine for the PCIA after abdominal operation shows significantly analgesic and sedative effects,and can notably improve the clinical symptoms,which is worthy of clinical application.

The differentiation of neural stem cells/neural precursors (NSCs/NPs) is a hot spot in neurobiological research. It used to identify their differentiation degree only by morphologic appearances. The functional characteristics, such as electrical properties of cellular membrane and ion channel activities, are drawing more and more attention with the development of patch clamp technique. It was summarized the recent progress in the study of NSCs/NPs functional differentiation using patch clamp, some existing problems and research perspectives were suggested.

Objective To construct mycobacterial membrane-anchored expression vector and to analyze expression level and sub-cellualr localization of exogenous target protein. Methods Based on the mycobacterial intracellular expression vector pMFA42 which contained a strong promoter of pfurAma mutant, the signal sequence of Mycobacterium tuberculosis(Mtb) 19×103 lipoprotein (19SS) was synthesized and was then cloned into the downstream of pfurAma mutant to generate the mycobacterial membrane-anchored expression vector pMFA42M. The coding gene of enhanced green fluorescent protein(EGFP) was amplified by PCR, and then sub-cloned into these two vectors described above to construct recombinant EGFP fused and membrane-anchored strains, respectively. The coding genes of Mtb immuno-dominant antigens Ag85A and its chimera Ag856A2 were then sub-cloned intothe membrane-anchored construct pMFA42MG to produce recombinant Mtb antigen EGFP fused-expression strains. After that, expression levels and sub-cellualr localization of exogenous target protein were further analyzed by Western blot and flow cytometry sorting(FCS), and the fluorescence intensities of recombinant EGFP- expressed strains were observed in vitro directly and after transfection of murine macrophage cell line RAW264.7. Results The novel mycobacterial membrane-anchored expression vector was constructed successfully by introduction of signal sequence of Mtb 19×103 lipoprotein. Using of EGFP as model antigen, exogenous target protein was demonstrated to be expressed with high level and could be anchored into cell membrane of recombinant mycobaterial strains. Conclusion A novel mycobacterial membrane-anchored expression vector was constructed successfully to research recombinant BCG and functions of mycobacterial membrane proteins, and the constructed EGFP-expressed recombinant strains could also be used to research cytophagy in cell model and mycobacterial colony and translocation in animal immunization as model indicator bacteria.
