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 The study systematically reviewed the therapeutic effect of the Kidney-Nourishing therapy on aromatase inhibitor-associated bone loss (AIBL).Methods The databases CNKI, CBM, VIP, Medline and the Cochrane Library were searched. Cochrane collaboration's tool for assessing risk of bias was adopted to assess the quality of trials. The Revman 5.3 software was used for the analysis on the outcome index such as bone minernal density and the level of serum estradiol.Results Meta-analysis was conducted on 11 randomly controlled clinical trials. All 11 studies were concducted in China, and the quality of researches was low. Meta-analysis revealed that the decrement of bone mineral density in the group receiving kidney-nourishing herbs was significantly smaller than that in the control group(P<0.001), theMD was -0.070, 95%CI was (-0.087, -0.053), but there was no significant difference between two groups in the outcome of the serum estradiol level (P=0.159), theMD was -2.622, 95%CIwas(-6.273, 1.030).Conclusion Kidney- Nourishing herbs can delay the process of aromatase inhibitor-associated bone loss, but may not influence the serum estrogen level.

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).

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.

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.
