Objective To explore the early clinical characteristics of multiple system atrophy (MSA) in the elderly,and provide the basis for early diagnosis.Methods Totally 102 cases with probable MSA in elderly patients were retrospectively analyzed to understand the beginning symptom,clinical features and assistant examination results,combined with the literature review.Results Among the 102 cases diagnosed as probable MSA (61 cases were male and 41 cases were female),57cases (55.9％) were diagnosed as parkinsonism dominant MSA (MSA-P) subtype and 45 cases (44.1％) as cerebellar dominant MSA (MSA-C)subtype.In the beginning symptom,27 cases appeared autonomic dysfunction,including 15 cases (26.3％) in MSA P subtype and 12 cases (26.6％) MSA-C subtype; 14 cases manifested as dysuresia,11 cases as orthostatic hypotension,and 8 cases as sexual dysfunction.Parkinsonism as the beginning symptom was in 49 cases,among whom 24 cases were of abnormal gait,3 cases of resting tremor,16 cases of muscle rigidity,and 15 cases of slowed movement.Cerebellar symptoms as the beginning symptom were in 33 cases,with gait and limb ataxia of 27 cases,dysarthria of 6 cases,nystagmus of 2 cases.Pyramidal tract signs as the beginning symptom were in 2 cases.There was early misdiagnosis of 36 cases (35.3％).Conclusions As wide variety of early clinical features,MSA can be easily misdiagnosed.The clinical features and assistant examination should be paid attention to improvement of the accuracy of early diagnosis.

Objective To study the small intestinal absorption patterns of glimepiride in rats. Methods A rat model of small intestinal absorption in vivo was employed in this study. The small intestinal absorption rate of glimepiride was detected by high performance liquid chromatography. Results At the low and high concentrations of glimepiride, the average small intestinal absorption rates were 0.233 6 h -1 and 0.217 8 h -1 , respectively. Conclusion The small intestinal absorption pattern of glimepiride might be passive diffusion.

Objective To summarize the successful experience of radiodiagnosis specialist nursing model in our hospital.Methods Retrospectively analyze the course of establishment and development of radiodiagnosis specialist nursing model in our hospital.Many aspects including setting of the nursing unit,post,quota and salary,development of post responsibilities,systems,standards and procedures,establishment of quality control and performance evaluation system,standardization of the conventional specialist technology,study and application of the new specialist technology were expounded.Results Radiodiagnosis specialist nursing model had been established and improved after five years' exploration.Quality index of care,service and safety showed a steady upward trend.Specialist new technologies had prominent features.Teaching and research achieved initial success.Conclusions Establishment of radiodiagnosis specialist nursing model makes radiology nursing connotation more comprehensive.More importantly,it is of significance in guiding the development of radiodiagnosis specialist nursing.

Objective:To summarize endoscopic management of cerebrospinal rhinorrhea and position-determining means.Method:Fifteen cases of cerebrospinal rhinorrhea treated by endoscopic approach at our institution were analyzed retrospectively.Aetiology included accidental trauma (10), surgical trauma (4), idiopathic (1). All patients presented with CSF rhinorrhea.Six cases were operated after failure of conservative treatment. Two cases after failure of neurosurgical repair were referred to our department. The largest defect was as big as 2.5 cm×1.5 cm. All patients were scanned by computed tomography and magnetic resonance imaging and confirmed by biochemistry test.Ten patients received high resolution spiral computed tomography bonding ventriculography.Result:We performed intranasal endoscopic repair in all 15 patients. All repairs were successful at the first attempt with a mean follow up of 20 months. One patient had light headache postoperatively and relieved with conservative treatment. All defects of skull base detected by computed tomography and ventriculography were confirmed in the operation.Conclusion:Intranasal endoscopic repair of cerebrospinal rhinorrhea can be an effective method. High resolution spiral computed tomography scan combined with ventriculography is a precise position-determining means. With the advancement of instrument and operative skill,the scope of endoscopic repair will further extend.

Objective To synthesize glycylproline p-nitroanilide tosylate as a substrate for glycylprolyl dipeptidyl-aminopeptidase(GPDA),and to study its clinical application.Methods The title compound was prepared by DCC-HOBt synthesis.GPDA in human serum was detected by continuous monitoring method using substrate. Results The substrate with purity of 98.5% was obtained.The linearity of the method was up to 358.1 U/L.Intraassay CV and interassay CV of GPDA in diverse serum samples were 3.01% and 5.04%,respectively.It was shown that GPDA level in patients with hepatic cancer was significantly increased,while those in patients with gastric carcinoma and chronic gastritis were significantly decreased compared with that in the control group in clinical detecting(P

Objective: To explore therapeutic effects of calcium channel blocker combined statins on aged patients with hypertension, and their influence on inflammatory factor levels.Methods: A total of 124 aged patients with hypertension, who were treated in our hospital from Oct 2014 to Oct 2015 , were randomly and equally divided into amlodipine group (received amlodipine therapy based on routine treatment) and combined treatment group (received atorvastatin calcium based on amlodipine group) according to random number table.Levels of blood pressure, C reactive protein (CRP), interleukin (IL)-6, endothelin (ET) and blood lipids before and after treatment, and therapeutic effect and incidence of adverse reactions were compared between two groups.Results: Compared with amlodipine group after treatment, there were significant reductions in levels of systolic blood pressure [(143.57±3.14) mmHg vs.(131.73±3.42) mmHg], diastolic blood pressure [(82.17±3.26) mmHg vs.(76.51±3.27) mmHg], CRP [(7.32±0.71) mg/L vs.(5.57±0.76) mg/L], IL-6 [(133.42±27.31) ng/L vs.(123.73±22.81) ng/L], ET [(50.74±4.96) pg/L vs.(45.71±5.78) pg/L], total cholesterol [(5.32±0.66) mmol/L vs.(4.12±0.52) mmol/L], triglyceride [(1.56±0.42)mmol/L vs.(1.21±0.37) mmol/L] and low density lipoprotein cholesterol [(3.12±0.48) mmol/L vs.(2.43±0.43) mmol/L], and significant rise in high density lipoprotein cholesterol level [(1.41±0.12) mmol/L vs.(1.55±0.17) mmol/L] in combined treatment group, P<0.05 or <0.01.Compared with amlodipine group, there was significant rise in total effective rate (77.4% vs.91.9%) in combined treatment group, P=0.025.There was no significant difference in incidence rate of adverse reactions between two groups (P>0.05).Conclusion: Calcium channel blocker combined statins possesses definite therapeutic effects on aged patients with hypertension.It can reduce levels of blood pressure and blood lipids and inflammations and improve vascular endothelial cell function, which is worth extending.

Objective To evaluate the diagnostic value of serum M-type phospholipase A2 receptor(PLA2R) antibody detection for the diagnosis of idiopathic membranous nephropathy(IMN) by meta analysis.Methods By searching the databases of PubMed,Emabse,Wanfang and CNKI from inception to May,2017,all the literatures referred to serum PLA2R antibody for the diagnosis of IMN in both English and Chinese were reviewed and selected according to the inclusion and exclusion criteria.QUADAS was used to assess the quality of eligible studies.Meta-disc 1.4 was used to analyze heterogeneity and pooled effectsize and Stata 12.0 was used to analyze publication bias.Results A total of 20 studies with high quality were included.Heterogeneity test indicated there was no threshold effect.The pooled sensitivity was 0.69 (95 ％ CI:0.67 to 0.72),the pooled specificity was 0.97 (95 ％ CI:0.96 to 0.98) and the summary area under curve was 0.880.Sensitivity analysis indicated that the result was stable.Deek's funnel plot indicated there was no publication bias.Conclusion The sensitivity of detection of serum PLA2R antibody was acceptable for the diagnosis of IMN with high specificity,so more attention on PLA2R antibody should be paid in the clinical practice.
