Advances in ophthalmic surgery,together with achieving greater patient safety,have changed the requirements,methods and choice of regional anaesthesia of the eyes.So far,there still lacks of an absolutely safe ophthalmic regional block method,and the intraoperative anesthesia method depends on the needs of the surgeon and the expectations and the cooperation of the patients.The majority of ophthalmic procedures can be performed under regional anesthesia,but the proximity of important structures,such as the blood vessels,optic nerve and the brainstem,leads to increased risks associated with these blocks.The most serious one of these complications is brainstem anesthesia.An clear and full understanding of these complications,which may sometimes be life-threatening,is thus vital to the anesthesia practitioner.Procedural improvements include a close evaluation of the precise anatomy of the region,with particular attention to injection sites,depth of injection,position of the eyeball,and techniques to avoid nerve damage and accidental injection into surrounding structures,including blood vessels,eyeball and cerebrospinal fluid.To emphasize the importance of the prevention,recognition and management of these complications,which includes the extremely serious complication of brainstem anesthesia.

Objective To explore the application of ultrasound-guided femoral and sciatic nerve blocks combined with general anesthesia in lower limb fracture surgery.Methods Sixty four patients who received orthopaedics surgerywere randomly divided into two groups including combined group(n =32),control group (n =32).Control group was given general anesthesia alone,combined group was givengeneral anesthesia combined with ultrasound-guided femoral and sciatic nerve blocks.The intraoperative hemodynamic state at different time,anesthetic dosage,and agitation after waking upbetween two groups were compared.Results Compared with T1 moment,HR and MAP at T2 moment in both groups were significantly decreased (P ＜ 0.05),while all these indicators at T3-T5 moment had no significant difference compared with the T1 moment in combined group (P ＞ 0.05),while the difference was significant in control group (P ＜ 0.05).Compared with control group,combined group had less intraoperative propofoland fentanyl dosage during the surgery,shorter awakening timeand extubation time,and the difference had statistical significance (P ＜ 0.05).The incidence of agitation after waking up and degree of agitation was significantly decreased in combined group than that in control group (P ＜ 0.05).Conclusion Ultrasound-guided nerve blockade combined with general anesthesia for lower limb fracture surgery,canmaintain the stability of intraoperative hemodynamics,reduce the dosage of analgesic drugs,and promote early awakening and extubation.

Objective To study the growth inhibition of human hepatoma cells tranfected with type Ⅱ insulin like growth factor receptor (IGF ⅡR) antisense gene. Methods We constructed the recombinant eucaryotic expression plasmids of IGF ⅡR sense and antisense genes, which were transfected into SMMC 7721 human hepatoma cell line using calcium phosphate coprecipitation, and selected in DMEM supplemented with 500 ?g/ml G418(Geneticin) for 2～3 weeks. Then the total number of colonies formed was counted. The effect of IGF ⅡR antisense gene transfection on endogenous IGF ⅡR mRNA levels was examined by Northern blot, and the growth rate and the ability of the transfected cells to form colonies in soft agar medium were also examined. Results The hepatoma cells transfected with IGF ⅡR antisense gene exhibited significant reduction in endogenous IGF ⅡR messenger RNA(mRNA) levels and loss of their ability for anchorage independent growth in soft agar. The IGF ⅡR antisense gene supressed the formation of colonies of SMMC 7721 cells resistant to G418 without alteration on cell growth curve. Conclusion The IGF ⅡR antisense gene expression effectively blocks IGF Ⅱ to IGF ⅡR autocrine and/or paracrine signal transduction pathway and reverses certain aspects of the cell malignant phenotype.

Objective To compare the predictive power of model for end-stage liver disease(MELD) and Child-Turcotte-Pugh(CTP) on the cirrhotic patients who underwent transjugular intrahepatic portosystemic shunt(TIPS).Methods A total of 110 patients(98 males and 12 females) undergoing TIPS from January 2004 to March 2008 in our hospital were analyzed.Data of all patients were analyzed retrospectively.The main statistical tests included: Kaplan-Merier analysis to compare survival respectively,and the area of receiver operating characteristics(ROC) to compare the performance of the 2 models for predicting 3-month,1-year,and 2-year mortality.Results The survival rate rate of the patients whose MELD score under 15 showed significantly higher than the patients above MELD score 15.The area of ROC that predicting survival was 0.866 and 0.863 at 3 months,0.755 and 0.739 at 1-year,0.729 and 0.750 at 2-years respectively for the MELD and the CTP score.Conclusion Both MELD and CTP score can predict short-term survival accuracy,but poor in long-term.However,the MELD has overcome the shortcomings of CTP,and may be worth using in clinical.

Objective To investigate the effect of IVIG on pre-existing anti-HLA-A2 Ab levels and graft skin survival.Methods C57BL/6 wild type mice were sensitized to HLA-A2 by intraperitoneal injec-tion (IP) of HLA-A2 TgN mouse spleen cells (C57BL/6-TgN [HLA-2.1]1Enge SC) expressing human HLA-A2 at day 0, week 3 and 4.Sensitized mice were respectively treated with human IVIG , albumin, gly-cine, or PBS for 5 days during week 7.Skin transplantation from TgN mice to C57BL/6 wild type mice was performed at week 10 .Efficacy of IVIG DES was assessed by measuring anti-HLA Ab levels by ELISA pre-/post-Rx and graft skin survival was monitored daily post-Tx.Results Changes of HLA-A2-IgG levels:IgG HLA-A2 class I Ab levels in all groups predictably increased from baseline following spleen cell IP and peaked at week 4 ( P <0.01 ) , indicating sensitization .IVIG-treated mice showed significantly lower IgG Ab levels vs.albumin, glycine and PBS-treated at week 9 post-desensitization ( P <0.01).IgG quickly increased to extremely high levels in all groups following skin transplantation ( P <0.01 ) .Graft skin sur-vival between Rx-groups were similar with all rejecting at about 7 days post-transplantation ( P >0.05 ) . Conclusion However, IVIG alone does not inhibit anti-HLA class I Ab production after skin transplanta-tion or prolong SG survival , indicating combination of IVIG with other immunosuppressant or more optimal protocol for desensitization might show more efficacy and should be under explored .

Objective To investigate the effects of emulsified isoflurane on myocardial apoptosis, and the expressions of Bcl-2 and Bax after hypoxia/reoxygenation in cultured myocardial cells of neonatal rats. Methods Myocardial hypoxia/reoxygenation model was established on cultured primary myocardial cells of neonatal rat. The myocardial cells were divided into four groups: the normal group, model group, fat milk group, and emulsified isoflurane group. The cellular morphologic changes and pulsatile frequency of each group were observed under inverted microscope and the ultrastructure of myocardial cells was observed under transmission electron microscope. The apoptotic rate of myocardial cells was determined by flow cytometry, the expression of bcl-2 mRNA and bax mRNA were detected by RT-PCR and the protein expressions of Bcl-2/Bax were observed by Western blot. Results The apoptotic rate were significantly decreased in both emulsified isoflurane and fat milk groups (P0.05). Conclusion Emulsified isoflurane and one of its components, fat milk,can inhibit myocardial apoptosis induced by hypoxia/reoxygenation in cultured myocardial cells. Emulsified isoflurane exerts its anti-apoptosis effect maybe through up-regulating Bcl-2 expressions and down-regulating Bax expressions.

Objective:To explore the roles of the caudal ventrolateral medulla(CVLM) in the central anti-hypertensive mechanism. Methods : In 20 urethane-anesthetized SD rats, the effects of I1-imidazoline receptor and ?2-adrenceptor antagonists (microinjection into the CVLM) on the cardiovascular responses induced by intravenous clonidine were observed. Results: Prior bilateral microinjection of mixed antagonist idazoxan (I1-imidazoline receptor and a2-adrenceptor) into the CVLM not only decreased the mean arterial pressure [(-17. 3 ? 6. 9) mmHg, 1 mmHg = 0. 133 kPa, P
