Objective To explore the feasibility and operation methods of interforniceal diaterma keyhole approach for operative therapy of apex basilar artery aneurysm. Methods Interforniceal diaterma keyhole approach was designed to interpeduncular cistern with diaterma incision from tuber cinereum to posterior perforated substance and between bilateral mammillary bodies. The simulation operations of interforniceal diaterma keyhole approach were performed in 16 cadaveric heads by assisting with Stryker neuronavigation. Anatomic structures were observed by surgical microscope and measured by Stryker neuronavigation in the keyhole approach operations. Results The operations of interforniceal diaterma keyhole approach could be accomplished successfully in 16 cadaveric heads. The distances from bregma to superior margin of interventricular foramen, superior margin of adhaesio interthalamica, mammillary body, superior margin of aqueduct of midbrain and bifurcation of basilar artery were (68.4±4.6)mm, (66.3±6.0)mm,(86.3±5.3)mm, (82.0±7.6)mm and (91.8±5.0)mm respectively. The length of surgical window of diaterma was (9.5±2.6)mm from tuber cinereum to posterior perforated substance between bilateral mamillary bodies. The apex of basilar artery, P1 and P2 of posterior cerebral artery, superior cerebellar artery, posterior communicating artery and perforating branches from them could be exposed distinctly in interpeduncular cistern. The scope of operative exposure region was front to clivus and dorsum sellae by dissected the Liliequist panniculus, lateral to oculomotor nerve and posterior to interpeduncular fossa. The bifurcation of basilar artery apex was deviation to left in 68.8%. The bilateral posterior cerebral arteries were oblique to the anterolateral in 68.8%. There were 1-4 perforating branches from the apex of basilar artery in the included angle of bilateral posterior cerebral arteries. Conclusion Interforniceal diaterma keyhole approach is feasible for technique. It is worth of implementing and perfecting in surgical therapy of the apex basilar artery aneurysm.

Prediabetes is an abnormal condition between normal glucose metabolism and diabetes mellitus. Impaired glucose tolerance (IGT) is an indicator of high-risk state of prediabetes. Positive interventions of IGT, including life style changes and pharmacological intervention, can effectively postpone and reduce the development of prediabetes into type 2 diabetes mellitus, suggesting that IGT is a key point of diabetes prevention. Currently, pharmacological intervention for prediabetes is still at early stage. In this review, we summarizes recent clinical and preclinical studies on pharmacological intervention for prediabetes, and studies in the development of animal models with IGT and the application of new techniques. We also discuss the prospects of drugs for diabetes prevention, especially with the traditional Chinese medicine.

OBJECTIVE: To optimize the process of synthesizing aramchol. METHODS: Using arachidic acid (eicosanoic acid) and cholic acid as the starting materials, 3β-arachidyl-amido-7α, 12α-dihydroxyl-5β-cholanic-24-acid, a fatty acid bile acid conjugate aramchol, was synthesized through a 9 step route in which the carboxyl group and hydroxyl groups of cholic acid has been orthogonally protected and regioselectively deprotected. RESULTS: The yield of the target product was 12.7%. CONCLUSION: With reproducibile reactions, less by-products, and mild, controllable and relatively safe conditions, the improved process is very suitable for lab-scale production.

Objective To investigate the distribution of pathogenic bacteria,drug sensitivity,and the relationship between drug sensitivity and Escherichia coli(E.coli) induced enzymes in childhood diarrhea in the last 2 years in Chongqing area,so as to provide important evidence for pediatric clinical therapy.Methods Thirty-one E.coli induced enzymes,extended spectrum ?-laetamases(ESBLs),cephalosporinase(AmpC)detected in different phenotype methods,and drug sensitivity was measured in paper strip method,and the specimens were collected from children′s hospital affiliated to chongqing university of medical sciences from Jan.2005 to Dec.2006 were determined.Among the total,there were 18 enteropathogeic E.coli(EPEC) strains,8 enterotoxigenic E.coli(ETEC) strains and 5 enteroinvasive E.coli(EIEC) strains.In addition,drug resistance tests by paper strip included chloramphenicol(CHL),amikacin(AMK),gentamicin(GEN),norfloxacin(NOF),ciproflocacin(CIP),cefazolin(CEZ),cefoperazone(CPZ),ceftriaxone(CRO),ceftazidime(CAZ),cefotacime(CTX),cefepime(FEP),imipenem(IPM).SPSS 12.0 software was used to analyze the data.Results Three point two percent of the 31 E.coli were drug resistant to IPM,and 35.5%,38.7% to NOF,CIP individually,but more than 60% to AMK,GEN,even more than 67.7% towards cephalosporin(except ceftazidime and cefepime);the gross enzyme-produced rate was 87.1%,rate of single ESBLs,AmpC,and induction of both enzymes simultaneously presented 64.5%,6.5%,16.1% respectively;and there was marked difference in drug resistance when bacteria that produced single AmpC versus bacteria that produced single ESBLs or that produced both ESBLs and AmpC(Pa﹤0.05).Conclusions The relationships among enzyme′s quantity,sort and bacterial resistance are different.These data show E.coli infected by bacterial diarrhea children in Chongqing due to a high rate of induced enzymes,and their drug resistance vary according to the state of induced enzymes.

Objective To investigate the effect of vagina reconstruction using tissue-engineering biological material (acellular dermal matrix) in an animal model.Methods Vagina excision and vagina reconstruction with tissue-engineering biological material were performed in 12 Chinese experimental miniature pigs.The control group was matched with two of normal vagina specimens resected.At week 1,2,4,6,8,12 after surgery,the animals were sacrificed,respectively,and the neovaginas were prepared for immunohistochemical and Van Gieson (VG) staining to evaluate the status of various layer growth of vagina.Epithelial broad spectrum of monoclonal antibodies of AE1/AE3 and α-actin were used to test the existence of epithelial and smooth muscle tissue by immunohistochemical staining.The ultrastructure of neovagina was studied by transmission electron microscope at week 1 and 12 after surgery.Contractile function of isolated smooth muscle of neovagina was evaluated by chemical and electronic stimulation after 12 weeks' reconstruction.Results (1) Epithelization of 2/3 neovaginal mucosa was observed within 1 week.Only 1-2 layer epitheliums were observed under the light microscopy and epithelial cells with characteristics of loose and disarrangement were shown with the electron microscopy.Within 4-6 weeks,epithelization in mucosa of neovaginal canal was intensified to 4-5 layers.After 12 weeks,the differences between the neovagina and the native vagina were harldy noted either in the gross or microscopically.(2) After 4 weeks,a few smooth muscle cells were observed with VG and immunohistochemical staining,and homogeneous muscle bundle was formed.(3) After 12 weeks,similar contractile responses between neovagina and native vagina were observed when KCI and electrical stimulation with different frequency and voltage were given [(2.96±0.29)g vs.(3.14±0.30)g,(3.43±0.34)g vs.(4.65±0.73)g,(4.92±0.38)g vs.(4.89±0.44)g].Conclusion The tissue-engineering biological material might be an ideal graft used in the reconstruction of vagina.
