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.

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.

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.

Objective To study the expressions of Chemerin in hepatocellular carcinoma (HCC) and HCC cell lines,and to demonstrate the relationship between the expressions and prognosis.Methods The expressions of Chemerin protein in normal hepatocellular tissues,HCC and their paired tissues were detected by immunohistochemical staining of SABC; the expressions of Chemerin protein in HCC,cell lines and immortalized hepatocyte cell lines were detected by RT-PCR.Results The positive expression rates of Chemerin were 56.67％,90.00％,100％ in HCC,HCC cell line and normal hepatocellular tissues respectively,and the differences were significant (P＜0.05).The expressions of Chemerin mRNA in HCC paired tissues were higher than in HCC (P＜0.05).There was a higher expression of Chemerin mRNA in immortalized hepatocyte cell line LO2 ; but a lower expression in HCC cell lines.The expressions of Chemerin were related to lymph node metastasis,portal vein tumour thrombi,differentiation and TNM stage but not related to sex,age,tumour size,HBsAg and AFP.Conclusions Down-regulated expression of Chemerin may play an important role in the development,progression and metastasis of HCC.It may be a molecular marker for prognosis of HCC.

In recent years , the emergence and progress of cancer genomics and targeted therapies have remarkably expanded the application fields of protein-protein interaction in cancer research .Fluorescence resonance energy transfer ( FRET ) is a kind of nonradiation energy transfer technique , which can timing , quantitative , positioning , and dynamically monitor the interaction between protein and protein in living cells .With the discovery of novel fluorescent proteins and the development of FRET -based biosensors , FRET has became an important method for visualizing spatial and temporal dynamics of interactions among biological macromolecules in native environments .This review summarises the recent studies and technological advances that have enhanced the use of FRET tech -nology in cancer basic research , early diagnosis , prognosis evaluation , drug development and other areas .

Objective To evaluate the efficacy and safety of self-management anticoagulation treatment for low pulmonary embolism severity index (PESI) outpatient with acute pulmonary embolism (APE).Methods Sixty-eight patients with APE of PESI grade Ⅰ-Ⅱ were divide into inpatient group and outpatient group with 34 cases each by random digits table.All the patients were treated with low molecular heparin followed by oral anticoagulation,and self-management was used in outpatient group.The efficacy was observed within 14 days and 3 months.The efficacy outcome included recurrent venous thromboembolism (VTE),standardization time of international normalized ratio (INR),VTE-related emergency department visit times,bleeding events and total mortality.Results There were 2 cases(5.9％,2/34) in inpatient group and 1 case (2.9％,1/34) in outpatient group with recurrent VTE,and there was no statistical significance between two groups (P ＞ 0.05).Standardization time of INR in inpatient group [(8.5 ± 2.9) d] was shorter than that in outpatient group [(16.1 ± 4.4) d],and there was significant difference (P＜ 0.01).There was no significant difference in the VTE-related emergency department visit times between two groups (P ＞ 0.05).There was 1 case with major bleeding and 1 death respectively in outpatient group.Conclusion It is effective and safe to give early self-management anticoagulation treatment to APE patients with PESI grade Ⅰ-Ⅱ,which could shorten time spending in hospital and release burden both physically and mentally.

Objective To evaluate the efficacy of supportive psychotherapy on patients with cardiac neurosis. Method 32 patients with cardiac neurosis were treated with a comprehensive measure consists of adequate drug therapy and supportive psychotherapy. Symptom Checklist 90 (SCL - 90) was rated. Result Among the 9 factors of SCL - 90, scores of somatization, obsessive - compulsive, interpersonal relationship, depression, anxiety and phobic anxiety factors were significanly higher than that of normal controls. After treatment, the scores of somatization, depression, anxiety and phobic anxiety were statistically reduced. Patient- reported improvement efficacy was 84. 38%.Conclusion Adequate drug therapy together with supportive psychotherapy has reliable efficacy on patients with cardiac neurosis.
