Academic Journal of Second Military Medical University 1985;0(05):-
Objective:To assess the efficacy and tolerability of sibutramine as a weight reduction agent in treatment of overweight patients with type 2 diebetes.Methods: Forty overweight patients(body mass index ≥25 kg/m~(2)) with type 2 diebetes were randomized into sibutramine treatment group and control group(n=20).Both groups received a reduced-calorie diet(deficit of 1 045-2 090 kJ/d from an average daily intake) and continued their original treatment;sibutramine treatment group was also given sibutramine 15 mg once daily for 12 weeks.Before and after sibutramine treatment,body mass index(BMI),fasting blood glucose(FBG),fasting serum insulin(FINS),hemoglobin A_(1C)(HbA_(1C)),and serum lipids were measured in the patients.Homeostasis model assessment(HOMA) was applied to assess the status of insulin resistance(IR).Results: After treatment,BMI,FBG,HbA_(1C),_()TG,FINS and HOMA-IR all decreased(P

4.Expression of TAZ and β-catenin in colorectal carcinoma and their significance
Chinese Journal of Clinical and Experimental Pathology 2014;(12):1346-1349
Purpose To investigate the expression of TAZ and β-catenin in colorectal carcinoma and to analyze their correlation with the clinical pathological features of colorectal carcinoma. Methods The immunohistochemical method was used to detect the expres-sion of TAZ and β-catenin in 168 colorectal carcinoma specimens and 30 normal colorectal mucosal specimens. Results The positive rate of TAZ expression was significantly higher in colorectal carcinoma than that in normal colorectal mucosal (P<0. 01). The ectopic expression ofβ-catenin was significantly higher in colorectal carcinoma than that in normal colorectal mucosa (P<0. 01). The expres-sion of TAZ was correlated with degree of differentiation, lymph node metastasis, invasion depth and TNM stages (P<0. 05), and that of β-catenin was correlated with lymph node metastasis, invasion depth and TNM stages (P<0. 05). The positive expression of TAZ and the ectopic expression of β-catenin were significantly related to the 5-years survival rate ( P<0. 05 ) . The expression of TAZ was significantly positively correlated with the ectopic expression of β-catenin ( P<0. 01 ) . Conclusion Up-regulated expression of TAZ and ectopic expression of β-catenin may be synergistically involved in the occurrence, invasion and metastasis of colorectal carcinoma.

6.A Combined Optical Positioning Method Based on 1-D and 2-D Cameras.
Journal of Biomedical Engineering 2015;32(6):1310-1316
Optical positioning system has a wide range of application in many fields. This paper presents an optical positioning method which combines linear and plane cameras. 1-D image signal of linear camera is used to get 1-D coordinates of the targets, which can be processed quickly. We can use it to assist processing the 2-D image signals of plane camera under some constraints. Linear camera can reduce the amount of position searching and calculation in coordinates extracting of targets in 2D image, and it can also help identify multiple targets. The results showed that our method could reach an accuracy of 1.608 mm, which was about one thousandth of the measurable range, and the reconstruction time for 4 targets without geometric constraints is 23.87 ms, namely 41.9 fps.

7.CT Diagnosis of Mediastinal Teratoma
Journal of Practical Radiology 2001;0(06):-
Objective To discuss the CT features of mediastinal teratoma.Methods 35 patients with mediastinal teratoma confirmed by clinical and pathologic data were retrospectively analyzed.Results Most mediastinal teratomas(97.1%) were localized in the middle or upper area of anterior mediastinum.Mediastinal teratoma included cystic teratoma(60.0%) and solid teratoma(40.0%).All kinds of tissues could be found in the tumors.CT features of cystic teratoma(n=21) were the cystic mass with fluid density,most of them(n=19) had the characteristics of "obviouswalled cysts".CT features of solid teratoma(n=14) were the soft-tissue mass with mixed densities.CT features of malignant teratoma(n=5) were that the layer of fatty tissue between the tumor and the surrounding structures disappeared,and that the wall of neighbour vessels were mostly or all surrounded by the tumor.Mediastinal teratoma could cause pleural offusion(n=6) and pericardial offusion(n=12).Conclusion Mediastinal teratomas have obvious CT imaging features.CT has very important value in the diagnosis and differential diagnosis of mediastinal teratoma.
8.EFFECTS OF SIBUTRAMINE ON PLASMA NEUROPEPTIDE Y LEVELS IN PATIENTS WITH OVERWEIGHT AND SIMPLE OBESITY
Medical Journal of Chinese People's Liberation Army 1983;0(02):-
The aim of the study was to evaluate the effects of an anti obese agent, sibutramine, on plasma neuropeptide Y(NPY) levels in patients with overweight and simple obesity. 32 patients with overweight and simple obesity were assigned randomly to sibutramine group (group A) or placebo group (group B). Double blind rule was observed in the study. 16 healthy subjects served as control group (group C). Before and after six months of treatment, plasma NPY and serum insulin levels of patients in both groups were measured with radioimmunoassay (RIA). The results showed that fasting plasma NPY levels were higher in obese group than in control group before treatment .No significant difference was found between plasma NPY levels before and after the treatment with sibutramine. The study revealed that patients with overweight and simple obesity had elevated levels of plasma NPY. Sibutramine did not exert any influence on plasma NPY levels in these patients.
9.New understanding of hospital management after WTO accession
Chinese Journal of Hospital Administration 1996;0(10):-
The authors first expound that Chinas WTO accession has made it extremely clear that hospital management is the key to competition. There are two aspects of the issue. One involves changing management concepts, enriching management connotations, broadening the management horizon, enhancing management levels, transforming management mentality, and readjusting management structure. The other involves the application of modern management technology. Then they discuss ways of changing hospital management from the perspective of the competition for the masses of people seeking medical service. These include: ①attracting patients with easily available service; ②heavily advertising the hospital with specific images; ③displaying quality with standardized management; ④winning the confidence of the people with reasonable pricing. Finally the authors give a detailed account of how to explore human resources, retain talented people, form optimal teams, set up rational structures and raise assessment criteria in the competition for medical talents.
10.Hospitalized eye injury in a Chinese urban population: a retrospective analysis
International Eye Science 2010;10(10):1861-1863
AIM: To present the epidemiology, cause of injury, ocular status and final visual acuity after management of severe ocular trauma required hospitalization during 7 years in a representative urban Chinese population.METHODS: A retrospective analysis of the hospital admission files of ocular trauma patients admitted to the Daping hospital from January 2000 to December 2006 was carried out.RESULTS: A total of 268 patients were open-globe injury and the remaining 294 patients were closed-globe types. The most common causes of ocular injuries were metal (29.4%), explosive (14.6%) and stone (13.9%). And the visual outcomes of most of eye injury patients in this study were poor; half of injured eyes ended with visual acuity worse than 0.1.CONCLUSION: Therapeutic methods to ocular trauma make a great progress in recent years, but the visual outcomes are poor.
