UCH-L1(ubiquitin carboxy-terminal hydrolases L1)is a member of the carboxyl-terminal ubiquitin hydrolase family,naturally,that there is hydrolase activity,however,and that there is ligase acitivity,which is different from the other members of UCHs.UCH-L1 hydrolase activity could keep the pool of free ubiquitin and compromise the ubiquitin-dependent degradation pathway,while UCH-L1 dimerizational-dependent,ubiquityl ligase activity could produce undegradable,K63-linked polyubiquitin chains that could inhibit proteasomal activity.Therefore,UCH-L1 is involved in the more diverse physiological activities,including neuron formation,gonadal development and fertilization.Mutation of UCH-L1 is linked to the neurodegenerative diseases,such as Parkinson's disease.Moreover,abnormal expression of UCH-L1 is response to carcinogenesis in many tissue such as thyroid lung.

Objective: To evaluate the clinical efficacy and safety of nimodipine combine with butylphthalide in the treatment of patients with mild to moderate vascular cognitive impairment(VCI). Methods: From January 2012 to December 2016, 100 patients with mild to moderate VCI in Jinhua Municipal Central Hospital were randomly divided into control group(n=50) and treatment group(n=50) according to the random number table method.The control group received butylphthalide capsule, 200 mg po tid.The treatment group received nimodipine tablets, 40mg po tid, on the basis of the control group.The two groups of patients were treated for 24 weeks.Montreal cognitive assessment(MoCA), activities of daily living(ADL), serum hs-CRP, IL-6, TNF-α, clinical efficacy and adverse drug reactions were compared after treatment. Results: After treatment, the scores of MoCA and ADL in the treatment group were (24.32±2.87)points, (59.22±6.17)points, respectively, which were significantly higher than those in the control group[(22.76±2.67)points, (55.63±6.3)points, t=2.814, 2.870, all P<0.05]. The effective rates in the treatment group and control group were 74.00%(37/50), 52.00%(26/50), respectively, and there was statistically significant difference between the two groups(χ²=5.191, P<0.05). After treatment, the levels of hs-CRP[(189.51±23.27)mg/L vs.(211.51±25.51)mg/L], IL-6[(76.42±9.86)ng/L vs.(95.85±10.23)ng/L], TNF-α[(0.24±0.08)ng/L vs.(0.32±0.10)ng/L] between the treatment group and the control group had statistically significant differences(t=4.505, 9.670, 4.417, all P<0.05). The adverse drug reactions were nausea and vomiting in 3 cases in the control group(6.00%), nausea and vomiting in 3 cases and hypotension in 1 case in the treatment group(8.00%), and there was no statistically significant difference between the two groups(P>0.05). Conclusion Nimodipine combined with butylphthalide in the treatment of mild to moderate VCI is effective and has high safety.

Objective Based on the result of evaluating the nutritional state of in-patients using the methodologies of European Nutritional Risk Screening 2002(NRS 2002),we judged the rationality of nutritional therapy,and the rate of accepting nutritional therapy in hospital patients.Methods Totally 3567 inpatients consisted with the requirement of NRS2002 were investigated nutritional state and the situation of nutritional therapy within 2 weeks in hospital.Except BMI used as the standard of China,all the other methods were from NRS2002.Nutritional therapy included parenteral and enteral nutrition.Results In all objects,834 patients' number score was≥3(23.39%),and 256 got nutritional therapy among them(30.70%).The number of accepting nutritional therapy was 661(18.53%),and only 38.73% of them had a patient number score≥3.Conclusion NRS2002 is a good method to evaluate the nutritional state of in patients.The nutritional therapy should be on the basis of patient's nutritional state,but there isn't one specification in clinical nutrition-support.Many malnourished patients were ignored,while a lot of nutritional therapies were not suitable.Now one of method to solve this question is to set up Nutrition Support Team(NST).

Objective To investigate the effect of hexosamine biosynthesis pathway on the development of insulin resistance induced by high fat diet.Methods Normal male SD rats were randomly divided into three groups:control(fed with normal chow),high fat(fed with high fat diet for 13 weeks),and rosiglitazone (intragastric administration with rosiglitazone for 5 weeks)groups.After 13 weeks,all the rats were sacrificed,serum and muscle triglycerides(TG),serum total cholesterol(TC),and serum and muscle free fatty acids(FFA) were measured.Insulin sensitivity wss evaluated by insulin sensitivity index(ISI)and glucose infused rat(GIR) with the hyperinsulinemic englycemic clamp technique.The flux of HBP in skeletal muscle was detected with the expression level of glutamine-fructose-6-phosphate transaminase(GFAT)mRNA(RT-PCR),the content of UDPGlcNAc(HPLC)and the level of O-GlcNAc glycosylation in skeletal muscle proteins(Western blot). Results Compared with control group,senlm TG,TC,FFA and muscle TG,FFA levels of high fat group increased(aII P<0.01).both ISI and GIR decreased(both P<0.01),and the leveIs of GFAT mRNA(0.51±0.05 vs 0.18±0.02),UDP-GlcNAc[(6.18±0.86 vs 2.42±0.36)nmol/g],and O-GIcNAc glycosylation of skeletal muscle proteins in high fat group were raised(all P<0.01).In rosiglitazone group,serum and muscle TG.FFA welc deceased(all P<0.01).insulin sensitivity was increased(P<0.05)and the flux of HBP[GFAT mRNA 0.27±0.03,UDP-GIcNAc(2.62±0.32)nmol/g]was reduced(all P<0.05)as compared with high fat group. Conclusions High fat diet-induced insulin resistance in rats is correlated with the increased flux of HBP in skeletaI muscle.which is decreased by rosiglitazone.

P-glycoprotein (P-gp) is an ATP-dependent multidrug efflux pump that acts as a major obstacle for oral drug delivery and cancer therapy. Recent reports have provided evidence that excipients often used in pharmaceutical formulations, such as Pluronic and TPGS, also have inhibitory effects on P-glycoprotein. Because inhibition of efflux transporters by polymeric inhibitors may dramatically increase the bioavailability of P-gp substrates with negligible side effects, identification of the mechanism and their structure activity relationship is therefore of significant importance for pharmaceutical development. Other than competitive inhibition for traditional inhibitors, polymeric inhibitors may modify P-gp function through alterations on membrane fluidity, inhibition of P-gp ATPase, depletion of intracellular ATP and down-regulating of P-gp expression. In the present review, the inhibition mechanism of potential polymeric inhibitors and their structure activity relationship will be discussed along with a brief introduction to the established methodologies.

AIM:To observe the effect of atorvastatin(ATV) on myocardial ischemia-reperfusion injury and the role of inducible nitric oxide synthase (iNOS). METHODS: The rabbits were randomly divided into control group, ATV group, ATV+S-Methylisothiourea sulfate (SMT) group, SMT group. All rabbits were subjected to 40 min ischemia and 240 min reperfusion. The hemodynamic variables, CK-MB, LDH-1 and nitric oxide synthase were detected after reperfusion. RESULTS: LVDP and +dp/dtmax decreased by 24.6% and 35.3% respectively following ischemia-reperfusion. Pre-treated by ATV (10 mg?kg-1?d-1) for three days, LVDP and +dp/dtmax decreased by 21.7% and 41.3%, CK-MB and LDH-1 by 31.4% and 19.1% and iNOS increased to 102.6%. The reduction of LVDP and +dp/dtmax, CK-MB, LDH-1 and iNOS in ATV+SMT group was no statistically significant with those in control group. CONCLUSION: ATV pretreatment protected myocardial ischemia-reperfusion injury by upregulating iNOS.
