Correlation of atherosclerotic renal artery stenosis with coronary artery disease and peripheral arterial disease:a Meta-analysis / 重庆医学

Objective To systematically evaluate the relationship between atherosclerotic renal artery stenosis (ARAS) and cor‐onary artery disease (CAD) and peripheral arterial disease (PAD) .Methods We gathered all case‐control studies about the correla‐tion of ARAS with CAD and PAD in the following databases:Cochrane library ,PubMed ,EMBASE ,Web of science until April , 2014 .Two reviewers extracted all relevant datas from the screened documents independently according to exclusion and inclusion criteria ,RevMan 5 .2 software were used to conduct Meta‐analysis .Results Fourteen trials were included .Meta‐analysis showed that :the OR (95% CI)of CAD with 1 vascular lesions ,2 vascular lesions ,3 vascular lesions and left main stenosis ,PAD and ARAS were 0 .70(0 .59-0 .82) ,1 .28(1 .10 -1 .48) ,2 .09(1 .69 -2 .59) ,1 .82(1 .40 -2 .36) ,3 .68(2 .21 -6 .10) with statistical signifi‐cance (P<0 .05) .Conclusion CAD with 2 vascular lesions ,3 vascular lesions and left main stenosis ,PAD were connected with ARAS ,CAD with 1 vascular lesions has little relationship with ARAS .

The meta-analysis of the value of fractional flow reserve guided percutaneous coronary intervention for patients with multivessel diseases / 重庆医学

Objective To systematically evaluate the clinical outcomes of patients with multivessel diseases treated by fractional flow reserve (FFR) guided percutaneous coronary intervention (PCI) or other forms of treatment .Methods Some keywords inclu-ding FFR or fractional flow reserve ,percutaneous coronary intervention or PCI ,multivessel coronary artery disease were used to search randomized control trails(RCT) ,which compared outcomes of patients with multivessel disease treated by FFR guided PCI with other forms of treatment ,in Chinese and English database including CNKI ,VIP ,Wanfang ,Pubmed ,EMBASE and the web of science .The quality of included studies was evaluated by Jadad quality score and all the data was analyzed by stata 10 .0 .Results A total of 7 english literatures accumulating 2024 cases in experimental group and 7 284 cases in control group were included in this study .Compared with other forms of treatment ,patients with multivessel diseases treated by FFR-guided PCI had significantly low-er risk of myocardial infarction (RR=0 .72 ,P=0 .008) .Although the risk of death and major adverse cardiovascular events were al-so be reduced ,there were no statistically significant difference .Conclusion FFR-guided PCI is an effective treatment for multivessel disease ,but it is still needs further verification for the application in Chinese population .

Metrology management software for hospital metrology room / 医疗卫生装备

Since the hospital metrology station is the principal part of military metrology system,its handwrought operation greatly affects the working efficiency and implementation effects.In order to enhance working automatization,some metrology software was developed,but they only focused on the metrology management.This software achieves more functions such as auto-hint,auto-count of the inspection parameters,auto-output of the certification and so on.

Achieving circuit diagram of circuit board through digital camera / 医疗卫生装备

This paper introduces a method for drawing the circuit diagram of the circuit board rapidly. The pictures of the circuit board are taken firstly and then are imported into Protel. Also an example is given to explain the details. The method can simplify the drawing of the schematic for the circuit board, and thus is worth popularizing.
