Objective To conduct a meta-analysis of the curative effect and safety of the drug-coated balloon (DCB) and uncoated balloon (UCB) in treating femoropopliteal artery ischemic disease in order to provide more credible conclusion to guide clinical practice.Methods By retrieving relevant documents contained in Medline,EMbase,Cochrane library,EBSCO,Springer Link,Scopus,Web and other data pools,the research articles of clinical trials that met the inclusion and exclusion criteria were collected.According to the risk assessment standard of Cochrane collaboration network,the academic qualities of included articles were evaluated,the relevant data were extracted,then,the meta-analysis was conducted with RevMan5.3 software.Results A total of 8 papers were collected,which were originated from 6 clinical trials (from 2008 to 2015) and included 1188 patients in total.DCB group had 722 patients,and UCB group had 466 patients.Meta analysis showed that the target lesion revascularization (TLR) rates at 6,12 and 24 months after angioplasty in DCB group were significantly lower than those in UCB group.The late lumen loss (LLL) amount and re-stenosis rate at 6 month after angioplasty in DCB group were lower than those in UCB group.No statistically significant differences in amputation rate and mortality at 6,12 and 24 months after angioplasty existed between the two groups.Conclusion In treating femoropopliteal artery ischemic disease,the use of DCB is superior to the use of UCB in aspects of TLR rate,LLL amount and re-stenosis rate,besides,no significant difference in safety exists between DCB and UCB.Therefore,priority should be given to the use of DCB when the patient's economic conditions permit.

Objective:To study the effect of Liuwei Dihuang decoction (LW) on secretion of testosterone in the testis leydig cells of senescence accelerated mouse (SAM). Methods:The level of testosterone in the testis leydig cells of SAM with aging and the effect of LW on the secretion of testosterone were observed using cultured testis leydig cells in vitro.Results:The level of testosterone in the testis leydig cells of SAMP8 with aging was significantly decreased and showed a significant difference compared with age-matched SAMR1. Chronic administration of LW (2.5 and 5.0 g/kg) for 5 months significantly ameliorated the secretion of testosterone in SAMP8 compared with control group. Conclusions:The secretory function of testis leydig cells was reduced in SAMP8 with aging. LW ameliorated the secretion of testosterone in the testis leydig cells,indicating that LW could antagonize or delay the deterioration of the testis leydig cells in SAMP8.

Objective To explore the relationship between vascular lesions and benign paroxysmal positional vertigo in the elderly.Methods 74 patients aged 60 years and over with benign paroxysmal positional vertigo in Huanhu Hospital and 80 subjects without vertigo history in the medical examination center of the same hospital were randomly divided into the case group and the control group,respectively.The carotid intima-media thickness (CIMT) and plaque in the carotid artery were detected using high-resolution color duplex ultrasound for evaluating large vascular lesions.At the same time,T1WI,T2WI and diffusion weighted imaging (DWI) were performed with high-field 3.0 T MRI scanner as the detection index of small vascular lesions to compare the difference in severity of lacunar infarction,leukoaraiosis and micro hemorrhage between the two groups.Both indexes were used together to compare the overall difference in the intracranial and extracranial vascular lesions between the two groups.Results Between the case group and the control group,there were significant differences in the CIMT [(0.96±0.21) mm vs.(0.84±0.26) mm,t=3.136,P＜0.05],the detection rate of plaque (89.2％ vs.72.5％,x2 =5.803,P＜0.05),the number of lacunar infarction [(3.48± 1.67) vs.(2.34± 2.06),t=1.994,P＜0.05] and the score of white matter [(4.77±2.15) vs.(3.95±2.04),t=2.430,P＜0.05].There was no significant difference in the positive detection rate of the cerebral microbleeds in the case group and control group (22.9％ vs.17.5％,x2=0.4264,P＞0.05).Conclusions There is a relationship between the benign paroxysmal positional vertigo and intracranial or extracranial vascular lesions in the elderly.Vascular factor may play an important role in the pathogenesis of benign paroxysmal positional vertigo.Not only the atherosclerosis of large and small arteries but also the microcirculation disturbance may be partly attributed to the benign paroxysmal positional vertigo in the elderly.

qualitative and quantitative analysis of solid depolymerization products for supercritical methanolysis of ploy(ethylene terephthalate) polyester (PET) were studied by means of reversedphase high performance liquid chromatogr aphy on ZorbaxC8(4.6mm×250mm) with 70%(V/V) methanol as mobile phase. The results showed that the solid depolymerization products were mainly composed of dimethyl terephthalate (DMT), methyl(2hydroxyethyl)terephthalate (MHET), bis(hydroxyethyl)tere phthalate (BHET), dimers and oligomers, which could be separated effectively under the above chromatographic conditions. The calibration curves of DMT and BHET were linear in the range of 1.0～45 mg/L (n=8),r=0.9998～1.0000 and RSD＜2.8%. The determination limits of DMT and BHET were 4.0×10-4μg and 6.0×10-4μg respectively. 
