Diabetes mellitus is a common disease of serious harmful to human health,but its pathogenesis is not entirely clear.Mitochondria are the important organelles to generate energy in eukaryocytes,and play a pivotal role in the regulation of reactive oxygen species generation,intracellular calcium homeostasis,and apoptosis signal transduction.The possible causes of mitochondrial dysfunction include oxidative stress,Ca2+ disturbances,reduction of mitochondrial biosynthesis,opening of mitochondrial permeability transition pore,mitochondrial DNA mutations,and etc..Many studies demonstrate that mitochondrial dysfunction is associated with β-cell dysfunction of type 1 diabetes mellitus and insulin resistance of type 2 diabetes mellitus.Moreover,mitochondrial dysfunction plays important roles in the development of diabetic cardiomyopathy.This present article reviewed the current status of studies on the relationship of mitochondrial dysfunction and diabetes mellitus and diabetic cardiomyopathy.It is very important to understand and study mitochondrial dysfunction and its important roles in diabetes mellitus and diabetic cardiomyopathy in order to clarify the pathogenesis of diabetes mellitus and explore new approaches of prevention and treatment for diabetes mellitus.

Objective To investigate the value of combined detection of GGT,blood lipid and hs-CRP in patients with coronary heart disease.Methods Totally 134 patients with coronary heart disease and 38 patients without coronary heart disease were selected after coronary angiography.Coronary heart disease patients were divided into mild stenosis group (group A,n =40),Moderate stenosis group (group B,n =38) and severe stenosis group (group C,n =56) according to Gensini score.The age,sex,GGT,blood lipid and hs-CRP levels were detected in all groups,and t-he statistical analysis was performed by using SPSS 22.0 software.Results The level of GGT,TC,TG,LDL and hs-CRP in CHD group were all higher than those in non CHD group (P ＜ 0.05).The level of HDL was lower than that in the non CHD group (P ＜ 0.05).The level of GGT,TC,TG,LDL,hs-CRP in group B and C were higher than group A (P ＜0.05).The level of HDL in group B and C were lower than group A(P ＜0.05).The level of GGT,TC,TG,LDL,hs-CRP in group C were higher than group B (P ＜ 0.05).Logistic regression analysis showed that serum GGT,TG,hs-CRP were independent risk factors for coronary heart disease (P ＜ 0.05),HDL was an independent protective factor for coronary heart disease (P ＜ 0.05).Conclusion The combined detection of GGT,blood lipid and hs-CRP has important value in the diagnosis of coronary heart disease.

This article discussed the cultivation of Double Qualified Teacher for prosthetics and orthopedics education.

Spermatogenesis is a complex process. Current knowledge about human spermatogenesis is mainly based on the mouse model while little is known about the initial stage of this fundamental process in humans. The establishment of the model of spermatogenesis in vitro may contribute to an overall understanding of male germ cell development, an insight into the mechanisms of infertility, and clinical management of male infertility. This review summarizes current knowledge about the generation of germ cell-like cells from induced pluripotent stem cells (iPSCs) in vitro and discusses the potential application of iPSCs in the treatment of male infertility.

Objective To proceed deep data mining in large database obtained by Cancer Genome Anatomy Project and to distinguish the difference expression genes of gastric carcinoma.Methods The 300,783 serial analysis of gene expression records from 4 libraries of gastric cancer and 2 libraries of normal gastric tissue in database of the Cancer Genome Anatomy Project were analyzed by digital gene expression displayer.Results The 201 difference expression tags represented 136 genes(54 up-regulated and 82 down-regulated) and 65 ESTs(24 up-regulated and 41 down-regulated) were distinguished,and these genes were involved in biological process and signal transduction pathways,such as cell cycle regulation,cell proliferation and apoptosis.The gene expression profile in whole body normal and cancer tissues of PTMA were constructed by digital Northern based on serial analysis of gene expression database and by virtual Northern based on cDNA database,respectively.Conclusion The difference expression genes of gastric cancer can be distinguished effectively with bioinformatics,and the results will guide our further molecular biology research.If validated by molecular biology experiment,the difference expression genes will be used as molecular targets of gastric carcinoma.

It is well known that health education,as an effective intervention approach,plays an important role in the prevention and rehabilitation of coronary heart disease. This paper analyzed existing problems,corresponding solutions and research directions of the effectiveness evaluation indexes of coro-nary heart disease health education and proposed that China should build a standard,reasonable and perfect effectiveness evaluation index system of coronary heart disease health education which combines short-term and long-term evaluation indexes and some relevant standard scales, with the purpose of en-hancing the working efficiency of educators and promoting scientization,standardization and normalization of effectiveness evaluation of health education.

Objective To compare the effect of electroacupuncture at head points and body points on glucose metabolism of the cerebral motor function regions in normal subjects.Methods To observe the change of glucose metabolism of cerebral motor area in normal subjects between before and after acupuncture during the movement by PET.Talairach coordinates(Atlas of brain) and statistical parametric mapping(SPM) software were used to deal with the acquired imaging data.Results ① Acupuncture at Baihui(GV20) and left Qubin(GB7) could increase metabolism of glucose in bilateral Lps and precuneus,the activation of left area in the brain being more significant.②Acupuncture at right Quchi(LI11) and Zusanli(ST36) change metabolism of glucose in left gyrus precentralis,right loblus paracentralis,right gyrus frontalis medialis,both cerebellums and both putarnens.Conclusion All acupoints can change glucose metabolism in cerebral structures related to motor function in the bilateral cerebral hemispheres,different acupoints active different motor areas.The function of acupuncture is a kind of comprehensive regulative process.

Objective To explore the differences of using different analytic quality requirements in the comparable validation of blood cell analysis multi-system range test comparable schemes for establishing appropriate analysis quality standards for laboratory.Methods According to WS/T 407-2012 Guideline for Comparability Verification of Quantitative Results in Medical Institution,the range test comparable method was established.According to different sources of analytic quality requirements from the WS/T 406-2012 Analysis Quality Requirements of Clinical Hematological Detection Routine Items,the US Clinical Laboratory Improvement Amendment (88),GB/T 20470-2006 Requirements of External Quality Assessment for Clinical Laboratories and biological variations,corresponding analysis quality requirements standard was designed.Results With the standards designed by using WS/T 406-2012,CLIA′-88 and GB/T 20470-2006 as the analysis quality requirements,only the comparison results of low concentration levels in 3 items of HBC,PLT and HCT were not passed,while other results all were passed;all results passed the consistency verification by suitably revising the analytic quality requirements of low value concentrations.With the biological variations as the analysis quality requirement,the comparison results in WBC three concentration levels,and HBG high and low concentration levels were passed,but other results were not passed.Conclusion The biological variations analytical quality requirements are relative demanding.Using WS/T 406-2012 Analysis Quality Requirements of Clinical Hematological Detection Routine Items and GB/T 20470-2006 Requirements of External Quality Assessment for Clinical Laboratories,fully considering the suitability of low concentration quality requirements and formulating appropriate analysis quality standards of laboratory are the important contents of laboratory comparable validation scheme.
