Objective To explore the value of Ligasure and Ultracision in total laparoscopic hysterectomy (TLH). Methods From January 2002 to December 2006,totally 225 patients received total laparoscopic hysterectomy in our hospital. Among the cases,Ligasure was used in 152 patients,and Ultracision were employed in 72. The clinical data of the patients were reviewed. Results The mean operation time in the Ligasure group was significantly shorter than that in the Ultracision group [(104.9?29.2) min vs. (152.4?46.6) min,t=-9.329,P=0.000]. And the mean blood loss of the Ligasure group was significantly less than that in the other group [(32.9?14.9) ml vs. (126.4?12.1) ml,t=-46.710,P=0.000]. In both the groups,no patient was converted to open surgery or developed complications or surgical injuries. Conclusions Both Ligasure and Ultracision are safe and effective for total laparoscopic hysterectomy. Ligasure is superior in the management of uterine vessels,while the Ultracision is more effective in opening the vesicle and separating the cardinal ligament.

Objective To investigate the efficacy and safety of laparoscopic operations of ovarian tumors in children.Methods A total of 24 children with ovarian tumors treated laparoscopically from January 2000 to March 2005 were studied.The laparoscopic operations(tumor enucleation or unilateral adnexectomy) were conducted under general anesthesia with endotracheal intubation.Electrocoagulation of the capsule was performed alongside the borderline of the lesion for tumors 5 cm in diameter.After blunt dissection of the tumor and capsule,the lesion was completely enucleated.Hemostasis of the residual cut surface was accomplished by using electrocoagulation,with no need of suture. For large ovarian cysts disturbing laparoscopic visualization,the aspiration of hydatid fluid was conducted before the enucleation.Results All the operations were successful completed under laparoscope,including 24 cases of tumor enucleation and 2 cases of unilateral adnexectomy.The operation time was 50?20 min,the amount of hemorrhage was 30?10 ml,and the postoperative hospital stay was 2~4 d.No surgical complications or wound infection occurred.Follow-up in the 24 cases for 1 year found no recurrence.Conclusions Laparoscopic operations for ovarian tumor in children is safe and effective.

OBJECTIVE:To provide reference for rational use of drugs in hospital under the condition of the separation of drug and medical care. METHODS:The volumes of business,income from drug and income condition of medical staff were compared before and after implementation of separation of drug and medical care. The chance for pharmaceutical work under the condition of the separation of drug and medical care were analyzed to put forward advice for improvement of drug use in medical institutions. RESULTS & CONCLUSION:After conducting Wuhu model in 8 medical institutions,some achievement and experience have been obtained. It should be propelled to implement effective administration for rational use of drugs to resolve the problems on over expensive medical service.

Objective:To compare the time domain and the frequency domain of speech-evoked auditory brainstem response measured by stimulation of left and right ears, and to explore the difference and possible reasons of neural coding for speech from different ears in auditory brainstem.Method:Speech-ABRs to syllable /da/ of 31 healthy adults were recorded. Statistical analysis was performed on time-domain parameters, such as latencies and amplitudes of featured peaks, and frequency-domain ones, such as amplitudes of the fundamental frequency and the first formant of speech-ABRs ranging from 20-50 ms. A scoring criterion to grade the appearance of featured waves was proposed for waveform evaluation.Result:There were no significant difference for the latencies of binaural featured peaks and amplitudes of feature peaks(except peaks A and O). The waveform scores of right ear were greater than that of left ear. The amplitudes of fundamental frequency of binaural waves were both greater than that of the first formant. There was no significant difference of amplitudes of fundamental frequency and the first formant between two ears.Conclusion:The origins and distributions of speech-ABR are essentially symmetrical in brainstem in contrast with the hemisphere asymmetry of speech.

AIM:To study the chemical constituents of the leaves of Cyclocarya Paliums(Batal.) Iljinskaja. METHODS: Chemical constituents were separated through chromatographic methods and their structures were elucidated by spectral analysis. RESULTS: Six compounds were isolated from the chloroform fraction through 75% alcohol extraction from the leaves of Cyclocarya Paliums.Their structures were elucidated as ?-Sitosterol(1),Behenic acid(2),3?,20-dihydroxyl-5?-Pregnanes(3),Kaempferol(4),?-amyrin(5),?-amyrone(6). CONCLUSION: Compounds 3?,20-Dihydroxyl-5?-Pregnanes(3),?-amyrin(5) and ?-amyrone(6) are isolated from this plant for the first time.

Objective:To investigate the speech-evoked brainstem response (speech-ABR) of normal young people under different recording periods,which can provide the experimental evidences for researches on the stability of speech-ABR and promote its applications in clinical researches.Methods:40 healthy young people were randomly divided into two groups,which were tested following the same protocol at different time of two months interval.Latencies and amplitudes of the feature peaks in these groups were compared and the rates of appearance (detection rate) of the feature peaks were analyzed statistically.Results:Speech-ABRs were recorded successfully in two groups.The latencies and amplitudes of feature peaks in these groups were not different statistically,and the detection rates of V,A,C and F peaks were higher than others.Conclusion:The speech-ABRs of the two groups are stable,and the V,A,C and F peaks can be used as important indicators of clinical observation,showing that Speech-ABR is a promising tool in the study of Speech perception mechanism.

With the rapid increase of the number of cardiovascular disease patients in China, and the popular trend of cardiovascular disease risk factors is becoming more and more obvious, the control of risk factors for cardiovascular disease has become an important public health problem as well as a great challenge to social and economic development. Recent studies show that resistance training plays a positive impact on the control of risk factors for cardiovascular disease. This article reviewed the related literature in recent years for the resistance training control risk factors of the cardiovascular disease, and stated the precautions and challenges during the process of the implementation of resistance training in order to provide new clues to the research and practice for control the risk factors of cardiovascular disease .

Objective To analyze the airflow characteristics and investigate the relationship of the structure and the function of nasal cavity by the three?dimensional reconstruction of nasal airway of patients with structural abnormalities(nasal septum deviation)and healthy people and the estab?lishment of finite element model by computer. Methods On the basis of CT imaging of the nasal cavity in patients with structural abnormalities(na?sal septum deviation,n=20)and healthy people(n=20),three?dimensional reconstruction of nasal airway was conducted by resurfacing finite ele?ment subdivision to simulate the characteristics of airflow in nasal cavity. Results The airflow mainly went through the commodious side of the nose in patients with nasal septum deviation and the maximum fluence appeared in the middle part of meatus nasi communis. The airway pressure de?creased most significantly in the most flank?curvature part of nasal septum deviation,accounting approximately 79.65%of the total pressure. In healthy people,the bilateral airflow was affected by nasal cycle and was mainly characterized by one nasal cavity,and the maximum fluence was ob?served in the middle and the inferior part of meatus nasi communis. The airway pressure decreased most significantly in limen nasi,accounting ap?proximately 58.78%of the total pressure. Conclusion Numerical modeling of nasal cavity can be used to analyze the relationship between the nasal structural abnormalities and the airflow characteristics,which is a scientific method to analyze the association of nasal structure and function with dis?ease and can be used for pre?and post?operative individual evaluation of operative therapeutic regimen targeting at optimizing airway and altering air?flow distribution.
