OBJECTIVE To investigate the significance of Epworth sleepiness scale(ESS)and modified Epworth sleepiness scale(MESS),and evaluate the feasibility of MESS in assessment of obstructive sleep apnea hypopnea syndrome(OSAHS).METHODS The ESS and MESS of 232 patients with OSAHS was recorded in their first visiting.The scores of ESS and MESS were analyzed with the parameters of polysomnography(PSG). RESULTS Both ESS and MESS can reflect the degree of sleepiness and anoxemia in OSAHS patients,but the MESS was more efficient than ESS.The difference of MESS score between normal group and severe OSAHS group was greater than that of ESS score.CONCLUSION MESS is concerned the living habit of Chinese,and can partly reflect the station of patient with OSAHS.MESS can also be a primary screening method for suspected patients with severe OSAHS.

Objective To evaluate the clinical role of F-18 fluorodeoxyglucose (FDG)-positron emission tomography (PET) for the diagnosis and staging of prostate cancer.Methods 18F-FDG PET/CT and 99Tcm-MDP ECT whole body bone scan were both performed in 40 patients with prostate cancer proved by biopsy or surgery.We then evaluated the diagnostic value of 18F-FDG PET/CT for prostate cancer.Results Of 40 cases,17 cases were detected by 18 F-FDG PET/CT with a sensitivity of 42.5％.Of the 17 cases with lymphoma metastasis,8 cases were detected by CT while 15 cases were detected by 18F-FDG PET/CT.The sensitivity of 18F-FDG PET/CT is 88.2％.Though 18F-FDG PET/CT and 99Tcm-MDP bone scan have a similar sensitivity in detecting bone metastases,18 F-FDG PET/CT has better specificity and accuracy in detecting bone metastases than that of an 99Tcm-MDP bone scan.Conclusions Though the diagnostic value of 18F-FDG PET/CT in detecting primary focus of prostate is limited,it still has an important role in detecting lymph node metastases and bone metastases.18F-FDG PET/CT has its superiority in prostate cancer staging.It can also help clinicians to select the regimen of treatment.

Objective To explore the effect of three surgical positions on needle-assisted thoracoscopic sympathicotomy. Methods Sixty patients undergoing needle-assisted thoracoscopic sympathicotomy were divided into lateral position group，Fowler position group，and modified Fowler position group. The position of the endotracheal tube，noninvasive blood pressure (NIBP) and heart rate were monitored before and after the body position was changed. Moreover，the exposure of surgical field,operation time and comfort degree of patients were recorded. Results The operations were completed successfully under the three positions. Modified Fowler position provided better surgical field and higher comfort degree of patients. Moreover,it was convenient for operative procedure and shortened the operation duration. Conclusion During the operation of needle-assisted thoracoscopic sympathicotomy,modified Fowler position can provide better surgical exposure,enhance comfort of patients,stabilize hemodynamics and shorten operation duration.

Objective To investigate the character of real-time gray-scale contrast-enhanced ultrasonography (CEUS) and its clinical value in diagnosing hepatic focal lesion. Methods One hundred and three patients with 142 focal hepatic lesions were examined by CEUS after an intravenous administration of the contrast agent, then the characters of the images were analyzed. Results The initial contrast-enhanced signal patterns were classified into 5 modes, peak contrast-enhanced signal patterns into 4 modes, and contrast agent perfusion patterns into 7 modes. Different lesions had different characters of contrast-enhanced phases. The accuracy rate of the CEUS in diagnosing focal hepatic lesion was 93.0%. which was significantly higher than that of conventional ultrasound and contrast-enhanced CT (X2=47.430, P<0.05). Conclusions The characteristic initial contrast-enhanced pattern and contrast agent perfusion pattern are helpful in the differential diagnosis of hepatic focal lesion, while peak contrast-enhanced signal pattern is relatively unreliable. Compared with conventional ultrasound and contrast-enhanced CT, CEUS can dramatically improve the accuracy of qualitative diagnosis of hepatic focal lesion.

Objective To study the structure of class 1 integrons in 90 strains of Pseudomonas aeruginosa isolated during two periods of 1992-1996 and 2003-2005,and to get information about the structure changing of class 1 integrons by comparing their structures in two different periods.Methods Routine PCR and long PCR were performed to amplify the class 1 integrons and the gene cassettes they carried, followed with sequencing and blast via GenBank.Results Thirteen out of 41 strians ioslated during the period of 1992-1996 were positive on class 1 intergrons.Long PCR showed that the class 1 integron was 1868 bp in length and contained 2 resistance genes averagely.Six types of resistance genes of qacEA1 (n=6), sull (n=14),aadA1 (n=2),aadB (n=1),PSE-1 (n=2) and tetA (n=1) were found in these integrons, which consisted of 5 patterns of resistance cassette arrangements.Nineteen strains were proved to carry class 1 integrons in 49 isolates from 2003-2005.The mean DNA sequence length of them was 3383 bp with 3.6 resistant genes in averagely,10 types of resistance genes,qacEA1 (n=18),sull (n=25),aadA1 (n=6), aadB (n=7),aacA4 (n=2),PSE-1 (n=3),VEB-1 (n=4),OXA10 (n=1),cm1 A (n=1) and tetA (n =2),were identified in these integrons,which were composed of 9 patterns of resistance cassette arrangements.Conclusion In terms of produce length and resistance cassettes carried in the integrons, greater complexity is found in the structure of class 1 integrons in strains isolated during 2003-2005 than those during 1992-1996.
