ABSTRACT

Objective To analyze the problems found during the sampling inspection of the infusion and syringe pumps. Methods The present situation of the supervision of medical devices was explored,and statistical analysis was executed on the sampling inspection results of medical devices in 2016 to evaluate completely their quality and application.Results The medical devices had problems in uneven quality,low rate of coverage of sampling inspection,unreferencing YY 0709—2009 Medical Electrical Equipment-Part 1-8:General Requirements for Safety-Collateral Stanalard:General Requirements,Tests and Guidance for Alarm Systems in Medical Eleatriail Equipment and Medical Electrical Systems when registering product standard and technical requirements,external labeling,instruction manual and packaging.The qualification rate for sampling inspection was kept at low level in the past few years.Conclusion The supervision strategy is put forward for medical devices to enhance their overall quality.

ABSTRACT

<p><b>OBJECTIVE</b>To assess the association between single nucleotide polymorphisms (SNPs) of mannose-binding lectin 2 gene (MBL2) (rs1800450, rs1800451 and rs11003125) and protein kinase C-beta 1 gene (PRKC beta 1) (rs3700106, rs2575390) with diabetic macroangiopathy in northern Chinese Han population.</p><p><b>METHODS</b>The samples have included 318 type 2 diabetes mellitus (T2DM) patients and 448 normoglycemic controls. The five SNPs were determined by a Multiplex SnaPshot method. Biochemical indices such as fasting plasma-glucose, triglyceride and total cholesterol were also measured. Linkage disequilibrium and haplotype analysis were carried out for all samples using Haploview 4.2. Additive model was applied to assess the effect of interaction between SNPs and environment factors on macrovascular complications.</p><p><b>RESULTS</b>Genotypic frequencies of rs11003125 have differed significantly between the controls and patients with coronary heart disease and peripheral vascular disease (P=0.024 and 0.004, respectively). The allele frequency of rs11003125 was also statistically significant between the two groups (P=0.014 and 0.001, respectively). Compared with patients without macrovascular complications, the allele frequency of rs11003125 was significantly different in patients with peripheral vascular disease (P=0.031). No significant differences were found between the distribution of the genotype frequency and allele frequencies of other variants. Haplotype analysis indicated that, compared with controls and patients without macrovascular complications, individuals with G allele of rs1800450 and C allele of rs11003125 had a higher risk for macrovascular complications.</p><p><b>CONCLUSION</b>The rs11003125 polymorphism located in the promoter region of MBL2 gene is associated with macrovascular complications of T2DM in northern Chinese Han population. G allele of rs1800450 and C allele of rs11003125 may be risk factors for macrovascular complications. There were additive interactive effects for rs11003125 polymorphism (GC+CC) and hypertension, diabetic nephropathy, diabetic neuropathy and diabetic retinopathy on macrovascular complications.</p>
