Objective To observe the influence of Ginkgo laminae on serum lipid, serum level of homocysteine (HCY) and carotid intima-media thickness (IMT) of patients in recovery phase of cerebral infarction. Methods 100 patients in recovery phase of cerebral infarction were randomly divided into treatment group and control group, with 50 cases in each group. The control group were given aspirin enteric coated tablets 0.1g qn po., atorvastatin calcium capsule 20mg qn po.; the treatment group on the basis of the control group were added Ginkgo laminae, 1 tablet per time, three times daily. The blood liqid and HCY levels pre-treatment and 1, 3 and 6 months post-treatment and IMT value pre-treatment and 6 months post-treatment were collected. Results The triglyceride level had no significantly change in two groups. The high density lipoprotein cholesterol 3, 6 months post-treatment in treatment group was significantly higher than control group(P<0.05). The cholesterol and low density lipoprotein cholesterin 1 ,3, 6 months post-treatment in two groups significantly decreased compared with pre-treatment(P<0.05), while there was no significant difference between two groups at each time point. The cholesterol in treatment group had a smooth decreasing, while it had an increasing trend in control group 3 months post-treatment. The HCY 3 months post-treatment in treatment group was significantly lower than pre-treatment and control group 1, 3 and 6 months post-treatment (P<0.05). The IMT 6 months post-treatment in treatment group was significantly lower than control gorup(P<0.05). Conclusion Ginkgo laminae combined with atorvastatin for reducing lipid, which could raise high density lipoprotein cholesterol and reduce cholesterol smoothly and lower IMT, with the effective protection on vessel. The blood homocysteine level decreases after taking Ginkgo laminae for three months, which also could improve impaired endothelial function induced by high level of HCY and slow down the process of atherosclerotic plaque.

Objective To study the effects of vascular endothelial growth factor(VEGF) in early stage diabetic retinopathy and their mechanisms,so as to guide the clinical work theoretically.Methods Thirty-six SD rats were randomly divided into four groups.Nine rats were used as normal controls(M Group).Streptozocin were injected intraperitoneally to induce diabetes for 1 month(M1 Group),2 months(M2 Group),and 3 months(M3 group).At the experimental ends of each group,the rats were over anesthetized and their eyeballs were extracted to make digest preparation.Immunofluorescence were used to investigate the expression of VEGF on retinal blood vessels.Transmission electromicroscopy was used to observe the histology of the retinal vessels.Results VEGF immunofluorescence showed an expression rate of 56% in M2 group and 89% in M3 group.Transmission electromicroscopy showed no change in M Group.However,it showed swelling of endothelial cells,finger like process into the capillary cavity,uneven distribution of heterochromatin in pericytes in M1 Group.Obvious fragmental thickening and splitting of basement membrane,swelling and deformation,finger like process to the capillary cavity,and concentration and margination of heterochromatin in endothelial cells,and swelling and deformation of rough surfaced endoplasmic reticulum and mitochondrion in pericytes were observed in M2 and M3 groups,especially in the latter.Conclusion The expression of VEGF proteins in the retinas of diabetic rats increases with the progression of diabetes.It proves that VEGF plays an important role in the occurrence and development of early diabetic retinopathy.

OBJECTIVE:To promote rational drug use clinically. METHODS:Sampling rate of prescriptions in outpatient and emergency departments was no less than 1‰ of total prescriptions and no less than 100 prescriptions were reviewed every month;the sampling rate (according to the hospital records of discharge) of ward (district) doctor’s advice was no less than 1% and no less than 30 prescriptions were reviewed every month. According to drugs evaluation indicators of rational drug use,the prescrip-tions were analyzed statistically,immediate intervention and administrative intervention were adopted for irrational prescriptions and medical orders. RESULTS:The average qualified rate of outpatient prescriptions was 97.86%and 0.92%was non-standard prescrip-tions,1.20% was inappropriate prescriptions and 0.01% was extraordinary prescriptions. The non-standard prescriptions in the sec-ond half year were significantly lowered,with statistical significance(P<0.05). The inappropriate usage and dosage was not effec-tively controlled. The average qualified rate of medical orders was 96.30% and drug replacement withont any reference and incom-plete diagnosis in the second half year were significantly lowered,with statistical significance(P<0.05). The utilization rate of an-tibiotics in emergency department was 41.51%and the other indicators were basic standard. The qualified rate of Majing drugs’pre-scriptions was 81.60%and non-standard prescriptions accounted for 88.37%in the irrational prescriptions. CONCLUSIONS:Imme-diate intervention and administrative intervention have achieved some success. Immediate intervention has mainly reduced the non-standard prescriptions and administrative intervention has controlled some specific irrational prescriptions.

Objective:To investigate the value of serum anti-PLA2 R as a diagnostic marker of idiopathic membranous nephropathy( IMN).Methods:All available articles about serum anti-PLA2 R as a marker of IMN which were published at home and abroad from 2009.1 to 2013.12 were pooled from the databases of PubMed,Elsevier,Springer,CNKI,VIP and Wanfang database et al. The quality of the papers were evaluated by the quality assessment for studies of diagnostic accuracy studies( QUADAS).And then a meta-analysis was conducted by the statistical softwares of Meta-Disc and Stata.The diagnostic value of serum anti-PLA2 R in IMN was evaluated by the statistical indicators of pooled sensitivity, pooled specificity, pooled likelihood ratio and summary receiver operating characteristic curve( ROC curve).Sensitivity analysis was performed by reducing a paper in order,and publication bias was tested by Egger funnel plot.Results: Seven articles were selected to the meta-analysis according to the inclusion criteria and 967 cases were included in the study ( 454 IMN patients and 513 controls ).Heterogeneity test showed no heterogeneity threshold effect ( Spearman correlation coefficient was 0.107,P=0.819),but there was heterogeneity caused by non threshold effects(Cochrane-Q was 16.89,P=0.009 7).So random model was used to pool the effect size.The overall combined effect sizes:sensitivity was 69%,95%CI:0.65-0.73;specificity:98%,95%CI:0.96-0.99;pooled positive likelihood ratio 16.37,95%CI:4.06-65.95;pooled negative likelihood ratio 0.32,95%CI:0.24-0.43;AUC of SROC:0.854 0,Q*=0.785 0.Sensitivity analysis showed that this research was stable and reliable and Egger funnel plot showed little publication bias.Conclusion: Serum anti-PLA2 R is an useful biomarker to the diagnosis of IMN.

OBJECTIVE: To verify the relationship between THI and VAS scores in patients with sudden hearing loss and tinnitus in a prospective study. METHOD: Forty-four patients classified their tinnitus according to VAS and THI before and after treatment, and both scores were compared through the Pearson's correlation coefficient test and Nonparametric tests. RESULT: There was a correlation between VAS and THI scores in patients with sudden hearing loss and tinnitus. Tinnitus assessment scores were significantly reduced after treatment. Decreasing of THI and VAS scores were not depended on frequency and loudness of tinnitus and severity of deafness, but therapeutic effect of sudden sensorineural hearing loss. CONCLUSION THI and VAS scores are useful for assessment of tinnitus in patients with sudden hearing loss and tinnitus.

Objective To explore influence of perioperative protection from hypothermia on surgical site infection (SSI) in patients undergoing gastroenteritic operation. Methods A retrospective study was carried out in 1536 patients undergoing gastroenteritic operation in general surgery department of our hos-pital.Patients (764 cases) admitted before July 2006 were set as the control group,while those after July 2006(772 cases) were set as the observation group. The observation group received a series of measures for protection from hypothermia besides of routine perioperative nursing.The control group only adopted routine perioperative nursing.The SSI rate was compared between the two groups. Results The SSI rate of the observation group was lower than that of the control group(P < 0.01 ). Conclusions Incidence of periop-erative hypothermia in patients undergoing gastroenteritic operation can increase the SSI rate.Appropriate measures for protection from hypothermia can prevent the incidence of hypothermia as well as SSI.

Objective To investigate the clinical efficacy of combined detection of VCA-IgA and Rta-IgG in the diagnosis of nasopharyngeal carcinoma.Methods From May 2013 to November 2014, 3 913 serum samples(male 2 367,female 1 546) from healthy people who had health examination in our medical center were collected and 169 serum samples(male 118,female 51) were collected from the patients who were diagnosed as nasopharyngeal carcinoma by pathological biopsy.Serum samples in two groups were detected by EBV RTA-IgG, VCA-IgA assay ( ELISA ) respectively.SPSS17.0 statistical software and receiver operating characteristic curve ( ROC) were applied to data analysis.Results The Rta-IgG positive rates of EB virus were 93.5%in NPC group (158/169) and 2.4%(93/3 913) in healthy group;while the VCA-IgA positive rates were 79.3%in NPC group ( 134/169 ) and 8.9% ( 349/3 913 ) in healthy group. The sensitivity(χ2 =14.49,P<0.05) and specificity(χ2 =157.15,P<0.05) of Rta-IgG in the diagnosis of nasopharyngeal carcinoma were significantly better than that of VCA-IgA. Using VCA-IgA/Rta-IgG combined detection analysis, not only failed to effectively improve the diagnosis of nasopharyngeal cancer, but to reduce the detection sensitivity to 72.8%( 123/169 ) , compared with Rta-IgG detection only. Conclusions Rta-IgG is significantly better than that of VCA-IgA.There was no significant improvement in the clinical diagnostic efficacy of nasopharyngeal carcinoma using VCA-IgA/Rta-IgG combined detection mode.

Objective To assess the strain and synchronism of left ventricular papillary muscles (PM) in functional mitral regurgitation (FMR) patients using two-dimensional speckle tracking echocardiography,and to explore the relation of PM function and the development of FMR.Methods Sixty ischemic cardiomyopathy patients with FMR and 60 idiopathic dilated cardiomyopathy patients with FMR were prospectively recruited.They were divided into three groups as the degree of FMR,patients with mild FMR was group F1,with moderate FMR was group F2,with severe FMR was group F3.Control group involved 42 healthy volunteers.The longitudinal peak strain of anterior and posterior PM (ALS,PLS),the peak time of longitudinal peak strain (APT,PPT),and the delay time of peak value between ALS and PLS (DT) were quantified.Results The ALS and PLS decreased company with increased of FMR degree (P ＜ 0.05,respectively),whereas the DT increased (P ＜ 0.05,respectively),and there was no significant variation trend of the APT and PPT.There was no intergroup difference of ALS and PLS,APT and PPT (P ＞ 0.05,respectively).ALS,PLS had negative correlation with LVM (P ＜ 0.05,respectively),and positive correlation with LVEF (P ＜0.05,respectively).DT had positive correlation with LVM(P ＜ 0.05),and negative correlation with LVEF (P ＜ 0.05).Conclusions The dysfunction and desynchronization of PM are closely related to the severity of FMR.The results may helpful to screen proper patients for cardiac resynchronization treatment.

Objective To evaluate the diagnostic value of sympathetic skin response(SSR)in patients with vestibular vertigo.Methods SSR tests were performed on 1 20 patients with acute vestibular system vertigo,including 70 cases of central vertigo and 50 eases of peripherM vertigo.60 healthy subjects were also examined to serve as controls.Results In those with central vertigo,the abnormality rate in the SSR results was 87.1%(61/70).SSR latency was longer and its amplitude wag lower than in those with peripheral vertigo and in the heMthy controls.In those with peripheral vertigo the abnormality rate was 18.0%(9/50),but the average latency and amplitude were not significantly different from those of the healthy controls.Conclusion Persons with acute central vestibular vertigo may have sympathetic nerve dysfunction.SSR test results can be used as an electrophysiological index to distinguish central from peripheral vestibular vertigo.
