1.Reseach Progress on Molecular Detection Technology of Influenza Virus
Journal of Modern Laboratory Medicine 2016;(1):68-70
Influenza viruses are global epidemic and diversely difficult to distinguish,which threaten human’s survival and development very much.In recentyears,the frequent outbreaks of influenza prompt the rapid development of Influenza virus detection.Compare with the traditional isolated culture and immunological detection,molecular diagnostic technology is of high detection speed,high sensitivity and specificity,that gradually play an important role in the current Influenza virus de-tection.In order to provide a theoretical basis for the rapid diagnosis of Influenza virus in the clinic,the article summarize the update progress of molecular biology and diagnostic techniques of Influenza viruses.
2.Integrin-linked kinase and diabetic nephropathy
Journal of Medical Postgraduates 2004;0(01):-
Cellular functions like proliferation,differentiation,migration,morphogenesis and apoptosis are modulated by the extracellular matrix.Integrins are the prototypic heterodimeric transmembrane matrix receptors with competing affinities for individual extracellular matrix ligands.The intracellular integrin domain clusters cytoplasmic proteins into focal adhesion plaques for bidirectional(outside-in and inside-out) signaling.Integrin-linked kinase(ILK) is an intracellular serine/threonine protein kinase that interacts with the cytoplasmic domains of ?-integrins.ILK organizes the connections of the extracellular matrix via integrins to the cytoskeleton and is involved in adhesion plaque signaling,and it plays a crucial role in the pathogenesis of chronic renal fibrosis.High glucose induces the upregulation of the synthesis and activity of ILK in cultivated mouse podocytes and mesangial cells.The ILK protein level is significantly increased in diabetic glomeruli.ILK activity is likely to provide the basis for an effective therapeutic method for diabetic nephropathy.This review gives an introduction of ILK structure and function,followed by a summary of our current understanding of ILK in diabetic nephropathy with a special focus on glomerular cell-matrix interaction.

Objective To explore the effects of insulin pump on pancreatic ?-cells in type 2 diabetes mellitus accompanied with hyperglycaemia.Methods We treated 46 cases of newly diagnosed type 2 diabetes mellitus with fasting blood glucose≥10.0 mmol/L by insulin pump for 2 weeks.Their blood sugar and insulin were determined before and after treatment by oral glucose tolerance test and insulin releasing test.We then calculated the function index,morning secretion of pancreatic ?-cells and insulin resistance index.The patients were followed up for 6 months and the blood glucose was monitored.Results After treatment,insulin,function index and the morning secretion were increased significantly,while the blood sugar and resistance index were decreased.In all the patients,16 could maintain ideal blood glucose only by alimentary control and exercise.Conclusion With the insulin pump in a short term,patients with type 2 diabetes mellitus can rapidly control blood glucose,obviously improve pancreatic ?-cells,and reduce insulin resistance.
7.Inhibition of GDP on mitochondrial respiratory oxygen consumption and its effect on the mitochondrial membrane potential of rat brain
Journal of Third Military Medical University 1988;0(05):-
Objective To investigate effect of guanosine diphosphate (GDP) on the mitochondrial respiratory oxygen consumption and the mitochondrial membrane potential (MMP) of rat brain and explore the relationship of the change of uncoupling proteins (UCPS) activity with the oxygen consumption and MMP. Methods The mitochondria of rat brain were isolated by centrifugation. Mitochondria oxidative respiratory consumption was measured by Clark electrode after the treatment of GDP at different concentrations so as to calculate mitochondrial state 3 respiration (ST3), mitochondrial state 4 respiration (ST4), respiratory control rate (RCR), and the rate of oxidative phosphorylation (OPR). MMP was detected by Rhodamine 123 method at the different concentrations of GDP. Results With the increase of GDP concentration form 0 to 1.0 mmol/L, the values of ST3, ST4 and OPR were reduced while RCR was elevated. But when the concentration increased to 1.4 mmol/L, the former 3 indexes begun to increase while the later declined. When the GDP concentration reached to 1 mmol/L, the inhibitory rate was only 35.1%, 51.3%, 14.2% to ST3, ST4 and OPR respectively, while RCR was increased to 133.2%. No matter the concentration was over 1 mmol/L or under 1 mmol/L, the ability of inhibition was attenuated. MMP reached to the highest point when GDP exerted the highest inhibitory rate on mitochondrial respiratory oxygen consumption. Conclusion GDP, an inhibitor of UCPS, can regulate the respiratory oxygen consumption and MMP of the isolated rat brain mitochondrial directly in a dose-effect fashion. The change of UCPS activity can affect the respiratory oxygen consumption and MMP.

Objective To explore the influence of smoking upon the level of the serum interleukin and TNF-? in patients with bronchial asthma.Methods Sixty-five patients with bronchial asthma,grade 3 or 4 as asthma group and 50 healthy examinees as control group were selected.According to the smoking history,each group was divided into the smoking subgroup and the non-smoking subgroup.For each group,the level of cytokines in serum were detected,and at the same time,their smoking history and general condition were collected.The differences between the groups were compared and the relationship of all indexes was analyzed.Results Compared with the control group,the level of IL-2、IL-6、IL-8 and TNF-? of the asthma group was significantly higher(P0.05).The level of IL-2、IL-8 and TNF-? of the smoking asthma subgroup was significantly higher than the smoking control subgroup(P0.05).Conclusion The influence of smoking upon the level of cytokines of asthma patients is significant.The level of IL-8、TNF-? in serum of a smoking asthma patient increases.The level of five cytokines in serum of 65 asthma patients in our research is related to patient's condition severity.

Objective To explore the health inspector effect on the score of hygienic degree of hostels. Methods Using the scale for hygienic degree of hostels, 38 health inspectors from 9 sections in the Bureau for Health Inspection and Supervision of Haidian District in Beijing, scored 621 hostels in the district. The multilevel statistics model has been used to analyze the health inspector effect, of which the index is intra-class correlation (ICC), in the double level model structured by hostels as the level 1 unit and inspectors as the level 2 unit, and in the triple level model structured by hostels as the level 1 unit, inspectors as the level 2 unit and the sections as the level 3 unit. Results In the double level model, ICC of the level 2 unit is 0.142 8. In the triple level model, ICC of the level 2 unit is 0.0000 and ICC of the level 3 unit is 0.154 1. Conclusion There is inspector effect influencing the score of hygienic degree. And the effect seems to be more similar in one section comparing with the other ones.
