Purpose：To determine the treatments and prognostic predictors of malignant melanoma of the head and neck. Methods：Surgical treatment and outcome was analyzed for 28 patients with malignant melanoma of the head and neck at department of the head and neck of our hospital (1984-1994). Results：23 patients underwent local excised as the first treatment, and local recurrence was demonstrated in 8 (34.8%). Margin of resection of primary melanoma was divided into narrow excision (≤2 cm) and wide excision (＞2 cm), and 5-year survival was 58% and 40%(P＜0.01). According to surgical methods, 5-year survival of WE, WE/END and WE/TLND were 80%, 80% and 39%. Conclusions：An excision with 2 cm margin is safe procedure for primary tumor of malignant melanoma of the head and neck. Neck dissection may not be practiced until neck lymph node is positive. Neck dissections differ from the positions of the primary tumors, and the flaps must be raised preferably superficial to the platysma.

There was never a time in history that so many disciplines and specialists participate and try to lead the clinical management for acute pancreatitis. Chaos remains at bedside, and episodes of under-intervention and especially over-treatment frequently happened. Physicians are easily confused by questions and controversies in management for acute pancreatitis. We have reviewed the articles in acute pancreatitis and made our recommendations based on the latest evidences.

Efforts are being made to build up platforms to support basic research of ophthalmology by organizing capable staff,adequate instruments,technical assistance,and by applying practical evaluation and cultivating healthy cultural environment.While significant progress has been achieved with scientific publications and international academic exchanges,the ophthalmology society still has a long way to go to enhance the basic research in the field of eye science.Utilization of modern biomedical tools,technologies and strategies will undoubtedly further improve the efficacy and production in the area of basic research of ophthalmology in this country.

The incidence rate of erectile dysfunction (ED) is reportedly as high as 30-90% after radical prostatectomy for prostate cancer, which seriously affects the patients' quality of life. Penile rehabilitation is defined as the use of any drug or device at or after radical prostatectomy to maximize erectile function recovery. A variety of treatment options are available for post-prostatectomy ED patients, including oral phosphodiesterase 5 inhibitors (PDE5I) , intracorporal injections, vacuum erection device, and penile prosthesis. This article presents an overview of the currently used methods for the drug treatment and penile rehabilitation of the ED patients after radical prostatectomy. It seems proper to recommend daily use of a vacuum erection device plus oral PDE5I in the early postoperative period. For those who fail to respond to this therapy, intraurethral alprostadil, intracorporal injections, or a penile prosthesis could be considered.

This paper reports the study and design of a visualization system of the ultrasonic rhinitis therapeutic apparatus with the function of endoscopic sinus. On Linux operating platform, we captured the video data of a video capture card that connected the endoscopic sinus using Video4Linux (V4L2) that was provided by the operating system. The video images were displayed by Qt. The visualization system solved the problem that the current ultrasonic rhinitis therapeutic apparatus had to rely on the large and expensive endoscopy equipment. And this simplified the doctors' operation, met the need of monitoring nasal cavity in the process of operating, greatly reduced the costs of treatment and would contribute to the promotion of the instrument. As a result, it has been tested that the nasal endoscopic image achieved by the system is clear and smooth, and fully meet the clinical needs of ultrasonic treatment of rhinitis.

Objective To investigate MSCT findings of hepatic focal nodular hyperplasia(FNH),and improve its diagnostic value. MethodsThree-phasia MSCT scans of 16 cases with FNH confirmed by pathology were reviewed retrospectively. ResultsThere was single in 13 cases,double in 3 cases.17 lesions is hypodensity and 3 lesions is isodensity on plain MSCT.During MSCT enhancement all lesions were markedly and homogeneously enhanced in arterial phase.isodensity in portal and delay plase.1 lesion found scar. ConclusionDynamic contrast-emhanced MSCT could show the charcteristics of FNH.

Objective To understand the female sex workers and floating population in Yuzhong district of AIDS intervention effect ,To provide the basis for future planning of AIDS intervention in high-risk population .Methods 2011 in Yuzhong area ,By questionnaire survey and serological testing on 400 FSWs and 400 floating population .Results The rate of knowledge about AIDS among female sex workersis was 91 .75% ,higher than the floating population(73 .5% );female sex workers and floating population in a recent condom use rates was 74 .25% and 74 .71% ;the rate of condom insist to use was 48 .25% and 39 .08% ;the rate of Hiv prevalence was 0 .50% and 0 .75% .Conclusion To further increase the female sex workers and floating population coverage of in-terventions ,the role of a bridge cut off the high-risk groups in AIDS transmission of sexual contact ,and has important significance to the spread of AIDS control in Yuzhong District .

Objective To study the relationship between vascular endothelial growth factor (VEGF) and occurrence and invasiveness of bladder cancer. Methods The concentration of VEGF in urine was examined by ELISA in 36 cases of transitional cell carcinoma of bladder. Results The concentration of VEGF was low (3.73?2.63 pg/ml) in controls whereas it has been high in bladder carcinoma (210.97?154.68 pg/ml ), P
