Objective_To explore the effect and the mechanism of isoflurane on human cardiac myocytes ( HCM) injury induced by anoxia/reoxygenation ( AR) .Methods_HCM cells were divided into control group ( con) , an-oxia/reoxygenation group (AR) and isoflurane (0.5%, 1%, 1.5%and 2%) treatment group (n=6).Cell via-bility, LDH activity, apoptosis and the expression level of Anoxia inducible factor-1α( HIF-1α) were detected using CCK-8 assay, LDH activity assay kit, Annexin V-FITC/PI staining, PCR and western blot, respectively. Results_Compared with the con group, cell viability decreased, LDH activity and apoptosis cells increased in AR group.Isoflurane can significantly relieve the decrease of cell viability, the increase of LDH activity and apoptosis cells, and the down-regulation of the mRNA and protein expression level of HIF-1αinduced by AR ( P<0.05 ) . Compared with AR group, the mRNA and protein expression level of HIF-1αin siRNA transfected group signifi-cantly decreased (P<0.05).2%isoflurane significantly relieve the increase of cell viability, the decrease of LDH activity and apoptotic cells induced by HIF-siRNA in AR injuried HCM cells(P<0.05).Conclusions_Isoflurane can protect HCM cells from AR injury partly through up-regulate the expression of HIF-1α.

This study aimed to construct full-length cDNA clones of the Japanese encephalitis virus (JEV). SA14-14-2 strain and discuss the feasibility of constructing chimeric viruses for exogenous gene expression based on the JEV genetic skeleton. Long-fragment RT-PCR techniques were applied to amplify JEV cD-NAs, and two amplified fragments with corresponding restriction endonuclease sites at both ends were cloned into the pACYC184 vector sequentially. Using standard molecular techniques, the enhanced green fluorescent protein (EGFP) gene was inserted into the 3' non-coding region of JEV as a reporter gene. After in vitro transcription and transfection procedures, wild-type JEV and chimeric JEV that expressed the EGFP as the reporter gene were successfully rescued. The recovered viruses were characterized by RT-PCR, plaque assays, and direct fluorescence microscopy. After six serial passage generations, the stability of the recovered viruses were studied in terms of virus growth characteristics and structural gene expression. The results showed that cDNA clones of rJEV and rJEV-EGFP were successfully constructed and rescued in BHK-21 cells after in vitro transcription and transfection. Each generation of the recovered viruses was stable and the chimeric virus rJEV-EGFP could stably express EGFP. The findings of this study indicate that both rJEV and rJEV-EGFP could be constructed and rescued in BHK-21 cells, and the JEV SA14-14-2 strain could be obtained as a viral vector to express foreign genes.

ObjectiveTo investigate the effects of dexmedetomidine on postoperative cognitive dysfunction (POCD) in the elderly patients undergoing laparoscopic radical trachelectomy.MethodsSixty ASA Ⅰ or Ⅱ patients (aged 65-80 yr and weighing 55-74 kg) undergoing elective laparoscopic radical trachelectomy were randomly divided into two groups:30 patients received intravenous injection of dexmedetomidine 0.2 μg · kg - 1 ·h- 1 ( group D EX) and 30 received same volume of normal saline (control group,group NS) after induction of anesthesia.Cognitive function was assessed at 1 day before operation and on the 7th day after operation using a battery of nine cognitive dysfunction tests.ResultsCompared with group NS,on the 7th postoperative day,the incidence of POCD was decreased in group DEX ( P ＜ 0.05 ).ConclusionDexmedetomidine can improve POCD in the elderly patients undergoing laparoscopic radicaltrachelectomy.

Complications are always likely to occur in the treatment of fractures. Once fracture-related complications occur,their management will be difficuh,resulting in a long handling process that increases physical and financial pain on the patients.Fea- turing“management of fracture-related complications”,this issue intends to draw attention from orthopaedists to the challenging task of prophylaxis and treatment of such problems in clinic.Not only non-union,malunion,heterotopic ossification,bone necrosis but also such systemic complications as deep vain thrombosis,soft tissue infection and necrosis are discussed.They involve long tubular bones,pelvic,proximal femur,tibial plateau and calcaneum.Authors introduce their experience from their clinical practice which can benefit readers a lot.It is well known that an effective prevention is the best treatment.In treatment of fractures,principles must be strictly followed and preventive measures taken throughout the whole process.Once a complication has been detected,therapy should be individualized 1o gain the best outcome.

Objective To investigate the distribution characteristics of motor endplates in musculuslevatorani of dif-ferent gestational ages. Methods 20~24 weeks female fetuses were categorized as Group A, and 24~28 weeks female fetuses as group B. Karnovsky-Roots iron cyanide copper staining ( hematoxylin) was used to study the aver-age weight, the morphology, distribution and changes in number of motor end plate. Results The motor endplates morphology and distribution of consistent oval of 20 ~28 weeks female fetuses showed a curve distribution in the musculuslevatorani fibers foreign 1/3 . The weight and numbers of motor endplates in Group A were less than those of group B. Conclusion 20 ~28 weeks female fetuses' musculuslevatorani are visible on the motor end plates, and no significant difference is found in morphology and distribution of the curve along the muscle fibers. The num-ber of motor endplates increases with the increase of anal muscle weight mentioned.

Objective To observe the changes of intracellular free calcium and the expression of CaM in the hippocampal neurons of posttraumatic stress disorder (PTSD) rats and to further investigate the neurobiological mechanisms. Methods The SPS-method was used to set up the rat PTSD models. A total of sixty male Wistar rats were randomly divided into 12 hours,1 day,4 days,7 days groups of SPS and normal control group. The intracellular free calcium was examined by fluorescence spectrophotometer. The expression of CaM was detected by using immunohistochemistry, Western blotting and RT-PCR. Results The intracellular free calcium level in the hippocampus of experimental rats was markedly increased 12 hours after SPS stimulation,and reached the peak after 1 day, then gradually decreased to normal level after 7 days. The expression of CaM in the hippocampus 1day after SPS was also the highest and then gradually decreased.Conclusion The lasting dysfunction of Ca~(2+)/CaM signaling cascades in hippocampal may play important roles in the pathogenesis of PTSD rats.
