Objective To assess the changes on the whole night polysomnography (PSG) in patients with chronic fatigue syndrome(CFS). Methods The whole night PSGs were recorded from 24 patients with CFS and 33 normal subjects. Results Compared with normal subjects, patients with CFS showed significantly reduced total sleep duration ([488.7?21.7]min vs [515.9?31.7]min, P

OBJECTIVETo evaluate the indications and surgical procedure of bronchial and pulmonary artery sleeve resection for patients with centrally located non-small cell lung cancer, and how to prevent complications.
METHODSFrom July 1989 to Aug 2000, 32 cases of central NSCLC were treated with bronchial and pulmonary arterial sleeve resection and reconstruction. The results were retrospectively analyzed.
RESULTSThe complication rate was 25.0% (8/32), the mortality rate in 30-day postoperation was 6.3% (2/32), the overall 1-, 3- and 5-year survival rate was 82.8% (24/29), 50.0% (11/22) and 33.3% (4/12), respectively.
CONCLUSIONBronchial and pulmonary arterial sleeve resection and reconstruction in the treatment of patients with central NSCLC can not only maximize preservation of functional pulmonary parenchyma and improve patients, quality of life, but also provide an opportunity for those patients with poor pulmonary function to receive surgical resection of the tumor.

OBJECTIVETo compare the singing formant differences between successful opera actors and non-successful opera actors during their adolescence period, and to compare the same index between adolescence and adult period of successful actors.
METHODSFrom 1985 to 1986, the author had 21 adolescent actors' voice recorded, all of them were from Beijing KunQu opera troupe. In 2000, all the 21 subjects had their voice recorded and singing formant (Fs) analyzed by using computer and sound spectrograph, 7 of them had become adult actors, others quitted their actors career after adolescents period.
RESULTSuccessful actors have obvious Fs, and stronger acoustic energy; successful actors had weaker Fs value during adolescence period than during adult period (t = 2. 9600, P < 0.05).
CONCLUSIONFs's presence and its acoustic energy were important to evaluate adolescent actors future locality potential.

BACKGROUNDThe degree of pathological microvascular proliferation is an important element in evaluation of the astrocytoma grade. This study was aimed to quantitatively assess the microvascular permeability of brain astrocytoma with the volume transfer constant (K(trans)) and volume of extravascular extracellular space per unit volume of tissue (Ve) from dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and to evaluate the effectiveness of the K(trans) and Ve in the grading of astrocytoma.
METHODSThe highest values of the K(trans) and Ve of 67 patients with astrocytoma (27 with grade II, 12 with grade III, and 28 with grade IV) were obtained. The comparisons of the differences of the K(trans) and Ve between the different grades were conducted using the Mann-Whitney rank-sum tests. Spearman's rank correlation coefficients were determined between K(trans) values, Ve values and astrocytoma grades. Receiver operating characteristic (ROC) curve analyses were performed to determine the cut-off values for the K(trans) and Ve to distinguish between the different grades of astrocytoma.
RESULTSThere were significant differences (P < 0.001) between the different grades in the K(trans) values and Ve values, except for grades III and IV. The K(trans) values and Ve values were both correlated with astrocytoma grades (both P < 0.001). The ROC curve analyses showed that the cut-off values for the K(trans) and Ve provided the best combination of sensitivity and specificity in distinguishing between grade II and grade III or IV astrocytomas.
CONCLUSIONSDCE-MRI can play an important role in assessing the microvascular permeability and the grading of brain astrocytoma.

OBJECTIVETo evaluate the indications and surgery time of cochlear implantation in patients with otitis media with effusion (OME).
METHODSCochlear implantation was performed in 26 patients with bilateral profound sensorineural hearing loss and OME. Non-Surgical Treatment was conducted for OME before the following implantation. According to the standards of the indications and surgery time, surgery was carried out. During the process of surgery operation, related lesions of OME were completely removed and proper drainage was then constructed. After the surgery, the patients were regularly followed up, and the effective of cochlear implantation was evaluated.
RESULTSUnilateral ear of 26 patients was successfully operated. Among them, 5 cases were left ears and the remaining was right ears. All implant devices worked normally after 1 month. Had been followed up from 13 months to 4.3 years, 19 patients with OME were healed and the remaining was turning better. No evidence showed phenomenon of the eardrum perforation and acute attack of OME.
CONCLUSIONSOnce the indications of cochlear implantation in patients with OME are guaranteed, the surgery should be conducted as early as possible. The complications of cochlear implantation in patients with OME can be effectively avoided through proper treatment in different stages.

BACKGROUNDMost patients with auditory neuropathy (AN) could receive good even the best effects after cochlear implantation. How to diagnose AN objectively and accurately is very important. In this study, we screened the patients with AN according to the presence or absence of compound action potential (CAP) of intraoperative round window electrocochleography (RW ECochG).
METHODSIntraoperative RW ECochG was performed on 32 patients with profound sensorineural deafness, who had normal cochlea during cochlear implantation surgery under general anesthesia in the standard operating room. The cochlear microphonic (CM) and CAP of RW ECochG was observed and recorded.
RESULTSThe presence of CM but the absence of CAP of RW ECochG occurred in 12 among the 32 patients. They were suspected to suffer from AN. The rest patients who had CM and CAP of RW ECochG were thought not to suffer from AN.
CONCLUSIONApplication of intraoperative RW ECochG during the cochlear implantation surgery may objectively and accurately screen the patients with AN, and can give a meaningful clue for implanted device working.

OBJECTIVETo study the characteristics of inheritance and epidemiology of gallstone disease in one pedigree.
METHODSA gallbladder disease-specific questionnaire was administered to all family members to ascertain histories of cholecystectomy and other medical conditions as well as anthropometrical data. Laboratory examination and ultrasonography were performed to determine the existence of gallstone.
RESULTSOne hundred and thirteen members of four generations in the index family were enrolled in the study. The prevalence of gallstone in females (34.48%) was higher than in males (23.64%) but with no significant difference. The prevalence in the second and third generations (52%) was higher than in others (20%) (P < 0.05). The heritability and standard error showed as 86.38% +/- 46.46% in I generations. Body mass index, histories of hypertension, hyperlipidemia and blood glucose were positively related to gallstone disease (P = 0.012, < 0.01, 0.017, 0.043, respectively) in this family. Gallstone disease was not significantly related to history of diabetes, daily alcohol or diet habit. Plasma cholesterol and triglyceride levels were not correlated with gallstone disease.
CONCLUSIONGallstone disease presented aggregation in the family and was in accordance with the characteristics of autosomal dominant inheritance. Being female, obesity, hypertension and history of hyperlipidemia might serve as risk factors to this family.
