To explore the effects of two breathholding and exerting methods on the second labor course of primiparas.Methods Six hundred primiparas were divided according to the admission time into two groups: the control group and observation group. The former took conventional breathholding and exerting method and the latter breathholding and exerting method with breathing techniques. The two groups were compared in terms of outcome of delivery, rate of episiotomy, time for breathholding and exerting and the hemorrhage volume 2h after delivery, perineal laceration and neonate asphyxia.Results The rate of spontaneous delivery in the observation group was higher than that in the control group. The rate of episiotomy, bleeding volume 2h after delivery and perineal laceration were lower. The breathholding time was significantly shorter(P<0.05).Conclusion Breathholding and exerting at the second stage of labor can reduce energetic consumption and improve the outcome of delivery.

Objective To observe the analgesic effect of Qilong Toutong Granule and explore its underlying mechanisms of action. Methods Kunming mice were randomly divided into blank group, Zhengtian pill group, ibuprofen group, and high-, medium- and low-dose of Qilong Toutong Granule groups. After completing the prophylactic treatment for 3 days, hot-plate test and acetic acid-induced writhing test were used to observe the pain reaction of mice. SD rats were randomly divided into blank group, Zhengtian pill group, model group, rizatriptam group, and high-, medium- and low-dose of Qilong Toutong Granule groups. After gavaged for continuous 7 days, rats were intraperitoneally injected nitroglycerin (10 mg/kg), and 4 hours later, blood samples were collected from postcava for measuring the levels of plasma CGRP and β-EP by radioimmunoassay. Subsequently, rats were perfused transcardially and the brain tissues containing the trigeminal nucleus caudalis (Sp5C) were achieved for detecting the expression of Fos protein by immunohistochemical method. Results Qilong Toutong Granule significantly raised the pain threshold, reduced the number of writhing response of mice, remarkably down-regulated the levels of plasma CGRP, up-regulated the levels of plasmaβ-EP and inhibited the expression of Fos protein in Sp5C of rats compared with the model group. Conclusion Qilong Toutong Granule has good analgesic effect and its mechanisms on relieving migraine may be through regulating the levels of neurotransmitters or neuropeptides, and inhibiting the activation of Fos pathway.

Objective To compare the treatment effect of laparoscopic appendectomy(LA) and open appendectomy (OA). Methods One hundred and forty-five cases of LA performed from May 2003 to May 2005, and 142 cases of OA performed from June 2001 to March 2003 were studied retrospectively. Results There was no difference in operative time between group LA and group OA. In the procedure of LA, some occult disease could be discovered and treated, while OA was not. The administration of analgesic, activity time, incidence of incision infection and hospital stay in group LA were better than those of OA group. While the cost of hospitalization in LA was higher than that of OA. Conclusion LA has significant advantages in treating appendicitis and it should be promoted.

The principle on the pitting electrochemical noise detected by using wavelet transform was described briefly and the signal of pitting electrochemical noise was analyzed for commercial pure aluminum in 3.5 % NaCl solution. The result showed that wavelet transform could not only obtain the waveform characteristic of pitting signaland system noise in the multi-scale space, but also detect the waveform of pitting electrochemical noise according to the transmitting characteristic of the maximum module of wavelet coefficients, which represented the waveform characteristic.

OBJECTIVE To develop a method for the determination of theophylline in serum with concomitant use of ofloxacin.METHODS Theophylline was serum was extracted with chloroform-hexane(7∶3,v/v) after some ammonium sulfate was added.It was re-extracted with NaOH solution (0.1 mol*L-1)and detected with a UV spectrophotometer at 275 nm and 299.5 nm respeitively.RESULTS The method was linear over the range of 5.0~40.0 mg*L-1(r=0.9997,n=7).The average recovery of methodology was 100.3%(RSD=1.2%),and the extraction recovery from serum was 87.7%(RSD=4.6%).CONCLUSION This practical method for the determination of serum theophylline can eliminate the interference of ofloxacin and other antibiotics.

Objective To investigate the diagnosis and treatment value of laparoscopic surgery in tubal obstruction infertility patients with endometriosis.Methods Retrospective analysis was done in 381 cases underwent laparoscopic treatment for tubal obstruction from May 2005 to May 2010,,of which 119 cases were combined with endometriosis.The treatment results were analyzed,including the decomposition of the umbrella side tubal obstruction adhesions,lesions of endometriosis electrocoagulation,endometriosis cystectomy and pregnancy and so on.Results Hysterosalpingography(HSG)showed tubal occlusion in both side or one side in the distal end in 381 cases,and these patients were treated with laparoscopic surgery.There were 262 cases showed distal tubal occlusion not companied with endometriosis,of which 82 cases clinically pregnanced,accounting for 31.3%.Surgical treatment of endometriosis found in 119 cases,accounting for 31.2% ; and 29 cases pregnaced,which accounted 24.4%.We found 42 cases of tubal adhesions grade Ⅰ-Ⅱ and endometriosis stage Ⅰ-Ⅱ,16 cases of clinical pregnancy,accounting for 38.1% ;Twenty-six cases of tubal adhesions grade Ⅰ-Ⅱ and endometriosis stage Ⅰ-Ⅱ,7 cases of clinical pregnancy,accounting for 26.9% ;Twenty-eitht cases of tubal adhesions grade Ⅲ-Ⅳ and endometriosis stage Ⅰ-Ⅱ,4 cases of clinical pregnancy,accounting for 14.3% ;Twenty-three cases of tubal adhesions grade Ⅲ-Ⅳ and endometriosis stage Ⅲ-Ⅳ,2 cases of clinical pregnancy,accounting for 8.7%.The clinical pregnancy rate in the first group was significantly higher than the other groups,chnical pregnancy rate of the last group was the lowest.Conclusion Laparoscopic surgery is an effective treatment of tubal obstruction infertility combined with endometriosis.After laparoscopic surgery,the clinical pregnancy rate is significantly higher in Tubal obstruction without endometriosis than patients with endometriosis.After surgery,the clinical pregnancy rate in patients with the light stage tubal adhesions and endometriosis is better than those severely.

Aim To set up a highly effective and automatic mouse sleep-wake bioassay system,and evaluate the system through analysis of the somnogenic effects of L-stepholidine(SPD),targeting at dopamine D1/D2 receptors in mice.Methods The animals were housed in an insulated and soundproof recording chamber maintained at a constant temperature and humidity on an automatically controlled 12 h light/12 h dark cycle.The electroencephalogram and electromyogram were recorded continuously for 48 hours and analyzed by SleepSign software.Saline was administered ip to the mice at 21:00 on the first day,and SPD was given on the next day at the same hour.The vigilance state was analyzed based on the polygraphic recordings by the same software.Results The system has been demonstrated to be highly efficient and stable in recording and reliable in analyzing sleep-wake behavior in mice.With the aid of the sleep bioassay system,we found that SPD significantly increased the total time spent in sleep during dark period,and prolonged durations of non-rapid eye movement sleep episodes,with a concomitant reduction in amount and EEG power density of wakefulness.SPD rendered no effect on rapid eye movement sleep.Conclusion Through the reliable mouse sleep bioassay system,we found that SPD promotes non-rapid eye movement sleep but not rapid eye movement sleep in mice.
