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

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.

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.

Purpose To evaluate the correlation between acute pulmonary embolism (APE) and right ventricular parameters by multi-slice spiral computed tomography pulmonary angiogmphy (MSCTPA),and assess the severity and mortality of patients with APE.Materials and Methods The clinical and MSCTPA image data of APE patients from January 2012 to November 2015 was analyzed retrospectively.All the patients were divided into three groups according to the pulmonary embolism type and clinical prognosis:66 cases in mixed embolism group (25 cases of death,41 cases of survival);36 cases in peripheral embolism group,2 cases in centralembolism group.The CT post-processing software was used to measure thoracic aorta and main pulmonary artery inner diameter ratio (PA/AO),right ventricular diameter to left ventricular diameter ratio (RVD/LVD);right ventricular area to left ventricular area ratio (RVA/LVA) on axial four-chamber (4-CH) sections and the largest of maximum minor axis diameters on axial sections (RV/LV-LD).The difference of CT related right ventricular parameters among the mixed embolism groups,peripheral embolism and normal groups was compared.Results Statistical difference was found in right ventricular parameters (RVD/LVD,RV-LD/LV-LD,RVA/LVA) in mixed embolism death patients compared with the patients in other three groups (P＜0.05).There was significant difference of right ventricular parameters RVD/LVD,RVA/LVA in mixed pulmonary embolism survival patients compared with patients in peripheral pulmonary embolism and normal groups (P＜0.05),but there was no significant difference between peripheral APE patients and the control group in all RV and PA/AO parameters (P＞0.05).According to the result of ROC curve in mixed type embolism death patients,RVA/LVA was the best indicator of predicting early death (AUC=0.881),with 100.0％ sensitivity and 73.2％ specificity.Conclusion The right ventricular parameters by multislice CT pulmonary angiography can assess APE patient's condition and forecast their early mortality;and the clinical diagnosis accuracy of RVA/LVA is higher.

Objective To discuss the relativity between serum procalcitonin(PCT) level and renal impairment (RI) in critically ill patients. Methods A perspective study was performed in 60 critically ill patients. They were divided into 2 groups on the serum PCT level within 24 h: abnormal group (PCT ≥ 0.5 μg/L,38 cases) and normal group(PCT < 0.5 μg/L,22 cases). The serum creatinine (SCr) and blood urea nitrogen (BUN) were observed. Acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ ) of the patients were recorded. Calculated the sensitivity and specificity for prediction of RI as well as acute renal dysfunction (ARD). Results SCr [(188.91 ± 199.48) μmol/L]and BUN [(13.03 ±9.19)mmol/L]in abnormal group were significantly higher than those in normal group [(67.40 ± 15.35) μ mol/L and (6.91 ± 2.06) mmol/L](P< 0.01). The sensitivity of PCT forecast RI was 71.79%, and specificity was 52.38%. The sensitivity of PCT forecast ARD was 91.67% , and negative predictive value was 95.45%. Conclusion Serum PCT level has an important value for judgement of RI and ARD in critically ill patients.

Objective To examine the inhibitory effect of IL-2-PE40 on the mouse corneal allograft rejection. Methods A mouse corneal graft model was set up by using C57BL/6 mice as donors and Balb/c mice as recipients. In the treatment group, IL-2-PE40 (0.6 μg/g body weight) was intraperitoneally injected from the day of surgery every 12 h until rejection happened. In the control group, the equal volume of PS was injected intraperitoneally at the corresponding time points. The transplanted cornea was observed under slit-lamp twice a week and the transplanted corneal opacity and neovascularization were rated according to Horis grading standards. It led to the determination of rejection response. The survival of transplanted cornea was regarded to be stopped when the rejection occurred. The operated eyes were observed historically on the 10th, 15th, 25th and 35th day after the surgery, and the peripheral blood was collected for measurement of T cell subgroups and T lymphocyte colonies. Results The survival time of cornea in the treatment and control groups was (30.2±2.9) days and (15.1±2.1) days respectively. In the control group, rejection occurred on the 15th day after the surgery, CD4~+ cells started rise right after the surgery and increased most obviously on the 15th day [(63.9±4.0)%] and decreased afterwards. CD4~+ cells in the treatment group were increased slightly [(42.6±4.0)%] on the 15th day. The number of CD4~+ cells in the treatment group was obviously less than in the control group (P<0.01). No significant changes in CD8~+ cells were observed in both groups. The number of T lymphocyte colonies in the control group was increased at the beginning and dropped then. No obvious change was found in the treatment group. The number of T lymphocyte colonies in the treatment group was significantly less than in the control group (P＜0.01). Conclusion IL-2-PE40 is a highly specific immunosuppressive agent. It can delay the development of corneal graft rejection and reduce the percentage of T-helper cells significantly. It also works to weaken the forming capacity of the peripheral T lymphocyte colonies.

Objective　To observe the effect of nordihydroguaiaretic acid treatment combined with Methotrexate or Vincristine on a human malignant glioma cell line. Methods　The effect of drugs on the cells was measured by MTT, and the protein expression of cyclin D1 gene in the cells was measured by immunohistochemistry assay. Results　①The anti-tumor effects of drugs on the cells were increased with the increasing of concentrations, and had a combined function between NDGA and MTX or VCR. ②There was no difference between the effect of treating NDGA with MTX or VCR given at the same time and MTX or VCR given after 24 h of NDGA treatment, but the effects were apparently different when NDGA was administrated after MTX or VCR treatment for 24 h. ③The protein expression of cyclin D1 gene in the cells was apparently reduced after NDGA treatment. Conclusion　There is a cooperative function between NDGA and MTX or VCR on the cells, and the function is probably related to the NDGA-induced down-regulation of protein expression of cyclin D1 gene in the cells.

Central post-stroke pain refers to pain resulting from a primary lesion or dysfunction of the central nervous system after a stroke.The prevalence of central post-stroke pain varies from 8％ to 46％.This article reviews the definition,epidemiology,pathophysiology,clinical features,and treatment of central post-stroke pain.

The authors first expound that Chinas 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.
