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.

ObjectiveTo investigate portal hemodynamic features and its changes following devascularization in cirrhotics. MethodsHemodynamics of portal trunk (PT), right anterior branch (RAB) and splenic vein (SV), including maximum cross-sectional velocity(CS-Vmax), flow volume and congestion index(CI), were assessed in 69 cirrhotics and 46 normal volunteers by using a recently-developed color Doppler velocity profile(CDVP). Of 28 patients undergone devascularization procedure, portal hemodynamics were studied and compared before and after operation. ResultsCSVmax of PT and RAB was significantly lower in cirrhotic group than normal group;PT and SV flow volume and the ratio of SV to PT flow volume(SV/PT)were significantly greater in cirrhotic group compared with those of normal group;CI of PT, RAB and SV was significantly higher in cirrhotic group than normal group. Postoperative PT flow volume was significantly reduced( P ＜0.01),and the reduction was closely related to preoperative SV flow volume( r = 0.65, P ＜0.001). CS-Vmax and flow volume in RAB were decreased significantly following operation( P ＜0.01), and the reduction of RAB flow volume was highly related to preoperative RAB flow volume( r =0.74, P ＜0.001). After operation, free portal pressure(FPP)was declined by (6 ± 5)cmH2O[ (0.59 ± 0.49)kPa] ( P ＜ 0.001 ). There were no significant changes in CS-Vmax, CI in PT and CI in RAB following operation. ConclusionIn cirrhotics with portal hypertension, portal venous system coexists the elevated vascular resistance and hyperdynamics, but with different redorainance at different portion. SV hyperdynamics is the main source of increased portal blood flow. Devascularization procedure could markedly relieve portal hyperdynamics by elimination of SV inflow, which is one of the main mechanisms in obmining therapeutic goal. But the operation has no favorable effects on the increased portal resistance,and portal perfusion to the liver would be further declined after relieving portal hyperdynamics, which is unfavorable to maintenance of liver function.

A fungus that is capable of producing EPA and DHA was isolated from seawater. A fast extraction and methyl esterification of microbial lipid were established as well as their content determination by capillary gas chromatography using external calibration method. The results showed that the methyl ester prepared directly form the wet mycelia treated with CHCl3-KOH-CH3OH is less time-consuming and the method fits for the fast determination. To determine its EPA and DHA content,the wet mycelia was hydrolyzed according to Weibul 's method and the lipid obtained was methyl esteri.fied with KOH-MeOH,the results obtained by capillary gas chromatography using external calibration method were 7. 32% and 7. 58% respectively.
