Objective To investigate the correlation between cerebral artery stenosis (MCAS) and mild cognitive impairment (MCI).Methods Continuous selected 636 cases of 50-80 years old inpatients or outpatients who examined by transcranial color Doppler ultrasound (TCD) in April 2012 to April 2013 in our hospital.Keep the mini-mental state examination (MMSE) and clinical dementia rating (CDR) as the evaluation of cognitive function.Results Detected 124 cases of MCAS patients (MCAS group) and 512 cases of non-MCAS patients (non-MCAS group).Forty-four cases MCI were detected in MCAS group with the prevalence rate was 35.5％(44/124),and 114 cases of patients with MCI were detected in non-MCAS group with the prevalence rate was 22.3％ (114/512),the difference was statistically significant (P ＜ 0.05).Single factor analysis showed that there were no significant difference between two groups in waist circumference,hypertension,coronary heart disease,hyperlipidemia,smoking,diastolic blood pressure and total cholesterol,uric acid,fasting glucose,C-reactive protein (P ＞ 0.05); There were significantly different between two groups in age,gender,education level,MCAS,history of diabetes,systolic blood pressure and triglyceride,low density lipoprotein-cholesterol,high-density lipoprotein-cholesterol(P ＜ 0.05).Multiple factors analysis showed that the MCAS (OR =1.899,95％ CI 1.224-2.946),history of diabetes (OR =1.764,95％ CI 1.191-2.612),systolic blood pressure(OR =1.012,95％ CI 1.003-1.022),gender (OR =0.558,95％ CI 0.380-0.821),and age (OR =1.029,95％ CI 1.010-1.049) was the independent risk factor for MCI.Conclusion The MCAS related with MCI occurrence and development.

Objective To investigate the correlation of the middle cerebral artery stenosis (MCAS) and the mild cognitive function impairment (MCI),and the clinical efficacy of statins in patients with MCI. Methods Six hundred and thirty-six patientse,who received transcranial color doppler ultrasound (TCD)assay, were enrolled in our hospital hospitalization or outpatients. The simple mental state examination (MMSE) and clinical dementia rating scale (CDR) were used as cognitive function assessment indexes. Forty-four cases of MCI with MCAS and 58 cases of MCI with NMCAS were used as the treatment group , who received the atorvastatin 20 mg every day , 56 cases of MCI with NMCAS were used as the control group , who only received the routine and basic diseases treatment. One yearlater,we determined the changes of MMSE and CDRagain. Results We detected 124 patients with MCAS, 512 patients with NMCAS, and 44 cases of MCAS patients with MCI, the prevalence was 35.5%,114 cases of NMCAS in patients with MCI, with the prevalence of 22.3%, the prevalence between the two groups was statistically different. One year later, the patients in the treatment group, MMSE score was improved, the score of MCI of the MCAS group improved more significantly. Conclusion The middle cerebral artery stenosis correlated with the occurrence of MCI. Atorvastatin could improve cognitive function in patients with MCI, especially for MCI which was caused by middle cerebral artery stenosis.

Objective To analyze quantitatively the safety and efficacy of statin therapy in acute phrase for acute ischemic stroke with the method of meta-analysis.Methods We performed a systematic literature search including the Cochrane Library,MEDLINE and EMBASE for published trials about statin therapy and the outcomes of acute ischemic stroke.Then we performed a meta-analysis with included studies to investigate the association between statin therapy and clinical outcome and mortality.All of the data were pooled and meta-analyzed by Cochrane Collaboration RevMan 5.3 meta-analysis software.Statistical heterogeneity between studies was evaluated by the chi-square and I-square tests.Forest plots were used to summarize study data and Egger tests were used to assess publication bias.Results A total of 27 studies including 52 034 patients,comprising 19 212 statin users and 32 822 non-statin users met the inclusion criteria,4 studies were randomized controlled trials (RCTs),and 23 were observational trials (OTs).Both pre-or post-stroke statin use was associated with reduced mortality.Statin use is associated with favorable functional outcome at hospital discharge and on the ninetieth day regardless of initiation time for pre-stroke group and post-stroke group.The results from observational trials were consistent with randomized controlled trials.There was no evidence of publication bias for all comparisons by Egger tests.Conclusions Statin therapy before or after AIS is safe and effective.

OBJECTIVE:To prepare dexamethasone acetate borneol cream and to establish its quality control method.METHODS:Dexamethasone acetate borneol cream was prepared by grinding method;dexamethasone acetate and phenol were identified by TLC,and the content of the principal agent was determined by ultraviolet spectrophotometry.RESULTS:The prepared cream fitted the description of China Pharmacopeia(2005 edition) in identification and tests etc.The linear range of dexamethasone acetate was 12.06～28.14 ?g?mL-1(r=0.999 7),and the average recovery rate of 98.52%(RSD=0.66%).CONCLUSION:The preparation is reasonable in compounding,simple and feasible in techniques,and its quality is stable and controllable.

Objective To explore denture re-repair method, the key steps and the results. Method The clinical data of the 72 cases with complete denture re-repair were retrospectively malyzed. Results The results of repair of 48 cases were effective( 15 cases with one of titanium palatal care), accounting for 67 percent, repair,23 cases were effective, accounting for 32%, Repair ineffective in 1 case, accounting for 1%. Repair effect of satisfaction with the extent of alveolar bone absorption was no significant relationship between the 72 cases in the mandibular alveolar ridge had the 58 cases of Lowland Technology, accounting for 80%. Conclusions In the process of making dentures,it is necessary to carefully deal with every step to obtain good denture retention. Improve denture retention for denture repair is essential. Repair material selection and a good physician-patient relationship is also a help to enhance effect.
