ObjectiveTo compare the clinical efficacy and safety of anesthesia induction between inhalation of sevoflurane and intravenous injection of propofol for laryngeal mask airway (LMA) insertion in elderly patients.Methods40,ASA physical grade Ⅰ ～ Ⅱ patients scheduled to receive elective total knee arthroplasty were allocated to 2 groups at random. Patients in group one( G1 ) received intravenous induction of propofol infusion by a targetcontrolled infusion system which was set at the effect-site concentration of 4.0μg/ml,while patients in group two(G2)received inhalational induction with sevoflurane using vital capacity manoeuver at the target of end-expiratory concentration of 3.0％. We observed the whole procedure of anesthesia induction and LMA insertion, while recording the changes in hemodynamic state and occurrence of adverse events. ResultsMore than 85％ patients achieved LMA insertion at first attempt using either induction manoeuver. Although consciousness loss time in G1 was 39. ls longer than G2, there was no difference in anesthesia induction time for LMA insertion between these two groups. Contrary to a significant decrease in MAP following induction for patients in G1, there appeared hemodynamically stable in patients of G2,while apnea also significantly seldom occurred in G2 as compared to G1 (20％ vs 85％ ,P ＜0. 05).ConclusionAs compared to intrvenous induction with propofol, inhalation induction with sevoflurane provided a valuable alternative for LMA insertion in adults.

AimTo establish a model of the injury of the vascular endothelial cell(VEC) in rats and observe the function of Chinese herbs of Li Qi Huo Xue(LQHX) will prevent and treat the VEC injury. Methods30 SD rats weredivided into the control, the model and LQHX groups. The model of the VEC injury was established. It tried to demonstrate the effect of LQHX for the coagula tion and fibrinolysis function of the VEC by the C EC count,t-PA, PAI activity, 6-keto-PGF1αcontent and PAgTmax. Results In LQHX group as compared with those of the medol group, The CEC count was redued obviously(P＜0.01). t-PA activity was increased(P＜0.01), so did the percentage of active t-PA(P＜0.01), but PAI activity decreased (P＜0.05), 6-keto-PGF1α content increased (P＜0.01)α the PAgTmax decreasd (P ＜0.01) Conclution LQHX can enhance the anticoagulation and fibrinolysis activities. It is a more effective measure for the VEC protection.

Objective To study the apoptotic activity of hydroxycamptothecin (HCFT) against human gastric carcinoma and its mechanism of action.Methods The apoptotic activity of HCPT against gastric carcinoma SGC-7901 cells was detected by MTT assay.The apoptosis occurrence was determined by Annexin V/PI staining and flow cytometry analysis.The mRNA expression of Bmi-1 was detected by real-time PCR analysis.Western blot analysis was used to detect the protein expression of Bmi-1.Results The IC50 values of HCPT against gastric carcinoma SGC-7901 cells was (4.87 ± 0.35) μ mol/L.After treatment with 0,5,10,20 μ mol/L HCPT for 48 h,the percent of apoptosis was elevated from (1.62 ± 0.37)％ to (21.45 ±4.54)％,(36.67 ±5.38)％,(54.26 ±7.14)％ and the 2-△Ct values of Bmi-1 mRNA was decreased from 0.614 ±0.022 to 0.445 ±0.018,0.376 ±0.012,0.215 ±0.010,there had significant difference among the different treatment (P ＜ 0.01).Treated with 0,5,10,20 μ mol/L HCPT for 48 h,the protein expression of Bmi-1 was down regulated by HCPT treatment in a dose-dependent manner by Western blot analysis.Conclusion HCPT shows effective activity to induce apoptosis in gastric carcinoma cells,which is mainly related to the down regulation of Bmi-1.

Objective To observe the efficacy of pregabalin in the treatment of painful diabeticperipheral neuropathy.Methods In a 8-week study,50 patients were randomly assigned into two groups:the therapy group and the control group.The patients in the therapy group were treated with pregabalin 150 mg/d,and the patients in the control group were treated with carbamazepine 200 mg/d.The dose of pregabalin was increased to 300 mg/d till pain was alleviated in the therapy group,and the dose of carbamazepine was increased to 600 mg/d till pain was alleviated in the control group.The therapeutic effect and VAS score in the two groups were observed and evaluated.Results After 1 and 8 weeks' treatment,the therapeutic effect of therapy group were significantly superior to the control group ( At 1 week:U =2.028,P =0.046 ; At 8 week:U =3.540,P ＜0.001 ).After 1 and 8 weeks' treatment,the VAS scores of therapy group were significantly lower than the control group ( At 1 week:5.13 ± 1.76 vs.6.74 ± 1.52,P ＜ 0.05 ; At 8 week:1.13 ± 0.45 vs 3.27 ± 1.04,P ＜ 0.05).There were 5 patients (20％) and 10 patients (40％) had adverse reaction in the therapy and the control groups respectively.Conclusion Pregabalin is effective and safe for the treatment of painful diabetic peripheral neuropathy.

A highly sensitive immuno-PCR assay based on sandwich ELISA and PCR was developed to detect the circulating antigen in trichinellosis. Antigens were purified from the muscle larvae of Trichinella spiralis, and the myeloma cells were fused with spenocytes immunized with T. spiralis antigens to product the specific monoclonal antibodies. Indirect ELISA was used to select the antibody-secreting hybrodoma cells. By this method of procedure, monoclonal antibody F4C6 against the T. spiralis ES antigen was obtained, which was used as the indicator antibody, while the rabbit polyclonal antibodies against T. spiralis were to be used as capturing antibodies. The plasmid Bluecript Ⅱ KS was amplified by PCR with biotin-labeled primer M13-20, and thus the biotin-labeled DNA was obtained. Both the second antibody and DNA labeled with biotin were to be linked with 100 ng/ml avidin. The whole procedures of assay consisted of two steps, in which the circulating antigens were captured by monoclonal antibody through sandwich ELISA in the first step, and the DNA linked by monoclonal antibody was amplified by PCR in the second step. The sensitivity of this method was compared with that of the ELISA assay. It was found that the measuring ranges to detect the circulating antigens in trichinellosis were 50 pg/L to 0.005 pg/L for the immuno-PCR assay, and 5 μg/L to 0.05 μg/L for ELISA assay, the former was quite higher than that of the latter. It is evident that this method is highly sensitive for the detection of circulating antigens in trichinellosis.

Objectives To investigate the clinical features of Guillain-Barré syndrome (GBS) in children from Shen-zhen. Methods The clinical manifestations, results of electrophysiological tests and prognosis of 28 GBS patients from July 2002 to July 2012 were retrospectively analysed. Results Of 28 children, 16(57.1%) had preceding acute upper respiratory infection for 3-14 days but no patient had acute gastroenteritis. One had received HBV vaccination in 2 weeks before the onset of GBS. The peak season for GBS is spring. According to the clinical presentations and the neurophysiological results 17 patients had demyelinating neuropathy, 5 acute motor axonal neuropathy, 2 acute motor sensory axonal neuropathy, 3 Miller-fisher syndrome, and 1 polyneuritis cranialis. 14 (50.0%) patients suffered from pain in limbs which is the most nota-ble symptom in the early stage. Intravenous immune globulin (IVIG) and steroids were given during the acute phases in the majority of the patients, and assisted ventilation was performed in 2 patients due to respiratory muscle paralysis. No diffe-rence was found in Hughes scores, average hospitalization durations, and the prognosis between patients with GBS variants patients and patients with classic GBS. Conclusions Children with GBS in Shenzhen area have different clinical features.
