OBJECTIVETo explore the impacts on EC50 in the remifentanil inhibition of tracheal intubation response by the transcutaneous electrical acupoint stimulation (TEAS) at Hegu (LI 4) and Neiguan (PC 6).

METHODSForty patients with selective surgery undergoing endotracheal intubation with intravenous general anesthesia were divided into I to II degree by the American Society of Anesthesiologists (ASA) and were randomized into an observation group and a control group, 20 cases in each one. Before general anesthesia induction, in the observation group, the transcutaneous electric stimulation was applied to bilateral Hegu (LI 4) and Neiguan (PC 6) for 30 min, with dense-disperse wave, 2 Hz/100 Hz in frequency; in the control group, the sham-stimulation was applied to the acupoints, with the lamp on, but without electric current output. Afterwards, the general anesthesia induction started. When the target concentration of propofol and remifentanil was stabilized at the preset value, the endotracheal intubation was conducted. Dixon sequential method was applied for the determination of ECs in remifentanil inhibition of tracheal intubation response.

RESULTSThe level of EC50 in remifentanil inhibition of tracheal intubation response was 3. 46 ng/mL, 95% confidence interval was 2. 80 ng/ml to 4. 27ng/mL in the observation group; those were 4. 18 ng/mL and 3. 30 ng/mL to 5. 29 ng/mL in the control group separately. The differences were significant in comparison of the two groups (P<0. 01).

CONCLUSIONTEAS apparently reduces EChe in the remifentanil inhibition of tracheal intubation response by around 17%as.

Purpose:To investigate the therapeutic effect a nd toxicity of radiotherapy plus ultrasound hyperthermia for treatment of malign ant tumors. Methods:41 cases of locally advanced, recurrent or radioresista nt cancer treated from January 1997 to January 2000 were given radiotherapy plus Sonotherm 1000 ultrasound hyperthermia. The mean radiation dose was 61?12 Gy;h yperthermia was administered within 30 minutes following radiotherapy with mean heating time of (52.4?6) minutes at 1-2 times/week. 3-year local control and survival were estimated by Kaplan-Meier method and Log rank test, factors affec ting prognosis were analyzed by Cox regression. The significance of differences between temperatures was tested by one-way ANOVA. Results:There was significant difference between Tmin and Tmax on tumor local response. Tumor complete response was 58.5%, the 3-year local co ntrol and survival were 13.6%% and 32.69% respectively. There is significant cor relation between radiation dose, tumor volume, Tmin and 3-year local control ( P

Objective To study the value of hysteroscopy in the diagnosis and treatment of infertility caused by intrauterine lesions. Methods Hysteroscopic examinations and operations were performed in 82 cases of infertility caused by intrauterine lesions. Results No abnormal findings were found in 4 cases,while the other 78 cases of intrauterine abnormity comprised 23 cases of endometrial polyp, 29 cases of adhesive uteritis,18 cases of submucous myoma or adenomyosis, and 6 cases of uterine deformity. After hysteroscopic surgery and related treatment, the postoperative pregnancy rate reached 62 32% (43 of 69). Conclusions Hysteroscopy may be effectively used in the diagnosis and treatment of infertility caused by intrauterine factors.

OBJECTIVE:To explore the effects of alendronate sodium on bone mineral density (BMD) and bone marker in prostate cancer elderly patients after medical castration therapy. METHODS:In perspective study,84 elderly patients undergoing medical castration therapy were selected and divided into treatment group(45 cases)and control group(39 cases)according to ran-dom number table. Control group received medical castration therapy+Calcium carbonate D3 tablets,1 tablet,po,qn;treatment group was additionally given Alendronate sodium tablets 70 mg,po,once a week,1 week after routine treatment,on the basis of control group. Treatment course of 2 groups lasted for 12 months. The levels of 25-OH-D,testosterone,BMD and bone marker were observed in 2 groups,and the occurrence of ADR was recorded. RESULTS:3 cases of treatment group and 1 case of control group dropped out of the study. Before treatment,there was no statistical significance in above indexes between 2 groups (P>0.05). After treatment,25-OH-D levels of 2 groups were increased slightly,but there was no statistical significance(P>0.05);tes-tosterone level of 2 groups were decreased significantly compared to before treatment,with statistical significance (P<0.05). 12 months after treatment,BMD of lumbar vertebra,collum femoris and hip were increased significantly in treatment group,while those were decreased significantly in control group;there was statistical significance in above indexes between 2 groups(P<0.05). The levels of N-terminal midfragment of osteocalcin,procollagen Ⅰ N-terminal propeptide and β-crosslaps were decreased signifi-cantly in treatment group,while those were increased significantly in control group;there was statistical significance in above in-dexes between 2 groups (P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Alendronate sodium can prevent bone loss and reduce the rate of bone turnover in elderly patients with prostate cancer receiving medical castration therapy.

Objective To construct short hairpin RNA (shRNA) recombinant expression vector for herpes simplex virus typeⅡ(HSV-2) UL29 gene and observe its inhibitory effect on HSV-2. Methods Four interference target sites of HSV-2UL29 gene were selected to construct 4 groups of small hairpin RNA respectively,named shRNA recombinant expression vector. The expression vectors were transfected into HEK293 cells with liposome. HEK293 cells were infected with HSV-2 after expression vector being transfected. The viral titer was estimated by end-point titration assay. The level of transcription was estimated by Real-Time PCR method. The expressing effect of protein was detected by Western-blot. Results Recombinant expression vector pGPU6/GFP/Neo-shRNA was constructed successfully. The result of end-point titration assay showed that the viral titer was reduced comparing with blank control (P<0.05). The result of RT-PCR showed that inhibition rates were respectively 28.80%, 59.95%, 66.08%and 36.27% comparing with blank control, and there were significant differences (P < 0.05). The effect of UL29shRNA1461 group was the best one. The result of Western-blot showed that the expressing quantity of ICP8 was reduced. Conclusion Recombinant expression vector pGPU6/GFP/Neo-shRNA can interfere HSV-2 UL29 gene expression from different cell level in vitro, which can inhibit the replication of HSV-2 genome in HEK293 cells. Thus, RNA interference (RNAi) is conducive to the further exploration of viral therapy.
