Osteoarthritis(OA) is a chronic progressive disease in the elderly, there are still no effective therapy for this disease. The objective of this article was to review progress in the clinical studies and therapies on the disease, especially NSAID therapy and total knee replacement.

Objective To compare the model for end-stage liver disease (MELD) and PT in survival prediction of hepatitis B patients with acute-on-chronic liver failure. Methods One hundred and thirty-nine hepatitis B patients with acute-on-chronic liver failure were divided into survival and death group, and evaluated by MELD and FT. The area under ROC curve was used to compare the MELD and PT. The mortality was observed within 3 months. Results The MELD score and PT of survival group was 25.09 ± 3.92 and (26.46 ± 6.46) seconds respectively, and those for the death group were 36.25 ± 6.42 and (40.78 ± 10.80) seconds. The differences were of statistical significance ( P < 0.01 ). MELD score showed significant correlations with PT(r =0.824, P <0.01). The area under ROC curve was 0.936 (95% CI 0.895 ± 0.977 ) on MELD score and 0. 890 (95 % CI 0.839 ± 0.941 ) on PT, and there was no significant difference between them. Conclusions Both MELD score and PT can accurately predict the short-term prognosis of hepatitis B patients with acute-on-chronic liver failure. The validity of prognosis by MELD is similar to PT. The mortality increases with the MELD score and PT increasing.

Through demonstrating the satisfaction evaluation system of Singapore hospitals,the article analyzed the differences between the satisfaction evaluation system of Singapore and the system made by Shanghai Municipal Commission of Health and Family Planning.It was concluded that the humanized evaluation methods should be highlighted,the conformity of establishment of evaluation system and policy be focused on,staff incentive mechanism be focused on and perfected,and patients' expectation indicator and perceived quality be considered as strategic tools to improve the healthcare system performance.

With the rapid development and wide application of forensic DNA technology, strict management and guidance are required. Conclusion could be gained the public and judge recognition, would be more scientiifc, accurate and convincing by using the standard operation. In recent years, forensic DNA standard technology has been rapid development, but there are still insuffcient. This paper will summarize the present situation and the existing problems of forensic DNA technology standards and prospects.

Objective Ethanol, acid and alkali were used in the traditional Bererine extracting which required quite a few extracting time and polluted the environment. Water instead of ethanol was used. Microwave irradiation was chosen as the extracting method. Methods The best parameters, microwave power, extracting time, solid-liquid ratio were got in the experiment. According to the orthogonal experimental design, the optimum extracting condition was determined. Results Microwave irradiation, compared with the traditional extracting techniques, was with short extracting time. Conclusion The method was practicable and the product possessed the virtue of high purity, safe quality and free pollution.

Vildagliptin is a potent and specific inhibitor of dipeptidyl peptidase 4,which has been implicated to enhance and prolong the physiological actions of incretion hormones including glucagon-like peptide-1 and glucose-dependent insulinotropic polypeptide.Vildagliptin is an orally administered drug and has been licensed for the treatment of type 2 diabetes mellitus.Vildagliptin monotherapy or in combination with other drugs can effectively lower glycosylated haemoglobin levels to a great extent.In addition,vildagliptin acts in a glucose-dependent manner,explaining its low risk of hypoglycemia.This drug has been proved well tolerated with few gastrointestinal side effects or oedema.Therefore vildagliptin is a promising new option for type 2 diabetic patients,and these patients would achieve better glycemic control and fewer complications in the long run.

BACKGROUND:Conventional treatments for hypertrophic scars include excision, steroid hormones, anti-metabolite drugs, immunosuppressive agents and radiation therapy. Easy to relapse or serious reaction limits their clinical use. In recent years, application of calcium channel blockers in treatment of hypertrophic scars has made more good progresses, but little adverse reactions are obtained. OBJECTIVE:To explore the effects of calcium channel blocker trifluoperazine on hypertrophic scar of rabbit ears. METHODS:A total of 24 rabbits were enrol ed in this study. After 1 week of accommodation, models of rabbit ear scar were established in accordance with the method of Morris and Li et al. Rabbit models were randomly assigned to three group (n=8). At 30 days after model induction, when scar formed, trifluoperazine and triamcinolone acetonide groups received trifluoperazine and triamcinolone acetonide injection. Blank control group was left intact. Changes in hyperplastic scar, hypertrophic index, levels of matrix metal oproteinase-2, tissue inhibitor of metal oproteinase-2, transforming growth factorβ1,α-smooth muscle actin and proliferating cellnuclear antigen were compared and observed in each group. RESULTS AND CONCLUSION:At 10 and 20 days after treatment, in the three groups, skin bulge was visible in rabbit ears and no rabbit hair grew. Rabbit ears had obvious softening in the trifluoperazine group compared with the triamcinolone acetonide group, showing dark red. In the blank control group, rabbit ear scar was evident and showed red color. At 20 days after treatment, scar thickness and scar index were lower in the trifluoperazine and triamcinolone acetonide groups than in the blank control group. Matrix metal oproteinase 2 expression was significantly higher, but tissue inhibitor of metal oproteinase-2 and transforming growth factorβ1 levels were lower in the trifluoperazine and triamcinolone acetonide groups than in the blank control group. Results indicated that trifluoperazine obtained good proliferative effects on rabbit ear scar, and could decrease scar thickness.

OBJECTIVE:To observe on the curative effect of compound glycyrrhizin in the treatment of chronic hepatitis B with hepatic fibrosis.METHODS:146cases of chronic hepatitis B with hepatic fibrosis were administered by i.v.drop daily for4weeks with compound glycyrrhizin injection40ml～100ml,into which5%glucose injection(250ml)was added,then a sequential therapy was adopted in which all the patients were treated with50mg oral compound glycyrrhizin tablets3times per day for3months.RESULTS:The total effective rates after4weeks of first stage treatment and the sequential therapy were67.12%and81.51%(P

ObjectiveTo study the effects of Shuxuening Injection on brain blood dynamics and neurological function in patients with vascular dementia.Methods60 patients with vascular dementia were assigned to two groups.31 patients were treated with routine therapy of internal medicine and Shuxuening Injection for two weeks,other 29 patients were treated with routine therapy of internal medicine only.The changes of brain blood dynamics,activity of daily living(ADL) and P300 before and 4 weeks after treatment were observed.ResultsThere were significant differences in brain blood dynamics,ADL and P300 after the treament between these two groups(P<0.05 or P<0.01).ConclusionShuxuening Injection can improve the brain blood dynamics in patients with vascular dementia obviously and accelerate neurological functional recovery.
