China Pharmacy 2001;0(08):-
OBJECTIVE:To investigate the pharmacotherapy for Parkinson disease(PD)and the factors influencing the choice of the treatment schemes for the PD patients.METHDOS:A total 269 patients with PD were assigned to 3 groups:Group I(Dopamine Agonist or Antan),Group Ⅱ(L-dopa),and Group Ⅲ(L-dopa plus Dopamine Agonist).The possible relative factors such as patients' age and sex,pathogenetic condition,educational level,occupation and income etc were analyzed statistically.RESULTS:The P value of the likelihood ratio test concerning the investigated factors such as age,sex,pathogenetic condition,education level,occupation and income were all less than 0.05 among patients treated with different kinds of therapy.The logistic regression analysis showed that all the six factors mentioned above had influence on the choice of therapy.CONCLUSION:The PD patient's selection of therapy was affected by his age and sex,pathogenetic condition,education level,occupation and income.

Objective To investigate the sensitization to HLA antigens and relationship between sensitization and allograft function after liver transplantation. Methods The panel reactive antibody (PRA) in serum was determined by using LAT ELISA kit in 15 recipients before and after liver transplantation. Results Moderate sensitization was detected in one of 15 cases before transplantation. The patient experienced one episode of mild rejection, which was reversed by treatment with Methylprednisolone. PRA in this patient maintained positive 3 months posttransplantation. The remaining 14 patients had negative PRA (

[Objective]To evaluate the accuracy of computer-assisted cervical pedicle screw installation and discuss the reasons of screw malposition.[Method]Totally 144 cervical pedicle screws were installed by computer-assisted navigation in 25 patients with lower cervical spinal disease.All the patients were examined by X-rays and CT after operation.Screw position and direction were measured on the sagittal and transsection image of intraoperative navigation and post-operative CT.The result was analyzed statistically.[Result]Two screws perforated the upper pedicle wall,3 deviated from the lateral pedicle wal1.There was no statistical difference in screw position or direction between navigation and CT image.Navigational images were based on the principle of rigid tissue.[Conclusion]Computer-assisted navigation can improve the accuracy of cervical pedicle screw installation.Screw malposition is responsible for the excursion phenomenon.

Objective To study the mechanism of paraquart-induced renal injury in rats,the expression of heine oxygenase-2(HO-1) and inducible nitric oxide synthase (iNOS).Methods 84 adult healthy Spragne-Dawley (SD) rats (female and male in half) were randomly divided into two groups,the control group (group A,n=42) and the paraquart group (group B,n=42).The rats in group B were treated with paraquart (25 mg/kg) intraperitoneally,the rats in group A were treated with the same dose of normal saline.Its histopathological change,the expression of HO-1,iNOS and evaluate the mRNA expression of HO-1 were observed.Results ①In group A,the tissue structure was clear without abnormal.In group B,there were obvious lesions in the renal tubule of cortical part,including cellular swelling,the canula narrow,the mesenchymal congestion and edema.These pathologic changes gradually reached the peak on the 1st day,and did not relieved till the end ofthis study.②In group A,there was no or weak expression of iNOS.At the 3rd hour,the expressions of iNOS in group B were observed in the kytoplasm of renal tubular epithelial cell and glomemlar endothelial cell of cortical part.It reached the peak on the 1st day and continued at a high level after that.③ In group A,there was no or weak expression of HO-1 and HO-1 mRNA.At the 3rd hour,the expressions of HO-1 in group B were observed in the membrane and kytoplasm of renal tubular epithehal cell of cortical part,immunohistochemistry score(IHS) was higher,the expression of HO-1 mRNA increased,there was a statistical significance between group B and group A(P<0.05).It reached the peak on the 1st day,and then decreased,there were 110 statistical difference between group B and group A on the 5th day(P>0.05).Conclusions HO-1 and iNOS ale involved in the procedures of renal injury,but its mode of action and regulating path still need further study.

HIV-1 integrase (IN) is a key enzyme for the viral replication. The protein-protein interaction (PPI) between HIV-1 IN and a cellular cofactor lens epithelium-derived growth factor (LEDGF/p75) is a validated target for anti-HIV drug discovery. In order to build the platform for screening inhibitor against PPI between IN and LEDGF/p75, the vector containing the LEDGF/p75 protein cDNA was constructed and expressed in Escherichia coli and the function of the LEDGF/p75 protein was assayed. The LGDGF/p75 encoding gene optimized according to the preference codon usage of E. coli, was synthesized and cloned into the expression vector pGEX-4T-1 to form a recombined plasmid, then transformed into host cell E. coli BL21 (DE3). The recombined clones were identified and confirmed by BamH I/Sal I digestion and sequencing, the successfully recombined plasmid in the host cell was induced by IPTG and the condition of the expression was optimized. The expressed protein was purified by the Ni2+ affinity chromatography column and SDS-PAGE was used to analyze the molecular weight and specificity. In addition, ELISA assay was used to analyze the function of the recombinant protein. The recombinant LGDGF/p75 was soluble, and expressed highly and stably in E. coli. The protein was proved to enhance HIV-1 IN strand transfer activity in vitro by ELISA. It will be helpful to build the platform of screening inhibitors against PPI between IN and LEDGF/p75.

BACKGROUND:Osteoperiosteal decortication can treat the bone nonunion effectively, promote healing of fracture, but its action principle and key operation are not very clear, and there is less research addressing the postoperative treatment. OBJECTIVE:To review research progress of osteoperiosteal decortication for treating nonunion. METHODS: China National Knowledge Infrastructure, Wanfang database and PubMed database were used to search the related articles. The retrieval key words were “osteoperiosteal decortication, stripping, bone nonunion, bone disunion, bone delayed union”. Osteoperiosteal decortications combined with other fixation methods to repair the healing of bone nonunion were compared and analyzed. Bone implantation and implant management were summarized during repair. RESULTS AND CONCLUTION:105 literatures were retrieved by computer. After primarily screening by reading titles and abstract, irrelevant and repeated literatures were excluded. Finaly, 45 articles were summarized. Action principle, indications and operating points of osteoperiosteal decortications for bone nonunion were summarized. Osteoperiosteal decortications combined with other different fixation methods for the healing of bone nonunion were compared so as to better serve the clinic. Simultaneously, the paper also explores the combination with bone implant and management of implant during repair. Osteoperiosteal decortication with its simplicity and effectiveness has been respected in the field of orthopedics. However, for special patients, such as patients combined with destructive bone disease, osteoporosis, nonunion of hand and foot short bones, the treatment with osteoperiosteal decortications needs further researches.
