Objective To study on the changes of the IL-6、IL-8、TNF-? in the type 2 diabetes with insulin resistance and the relation of plasma glucose or insulin resistance and cytokines. Methods (1) To assay the serum level of cytokines in 90 cases with type 2 diabetes mellitus (T2DM) and 30 normal controls. (2)To measure the level of fasting plasma glucose (FPG),hemoglohin A_1c (HBA_1c),fasting insulin(FINS),fasting C-peptide (FCP).(3) To analysis the relation of the level of FPG,HBA_1c,FINS,FCP and cytokines. Results (1) The serum levels of cytokines in T2DM group were significantly increase than in control groups,IL-6 and TNF-? in T2DM group with insulin resistance were significantly increase than in T2DM group without insulin resistance (2) There was significantly positively correlated between insulin resistance and the increasing of cytokine levels. Conclusion There is an excess activation of cytokines in T2DM,which is significantly correlated with insulin resistance. Cytokines play the important role in the occurrence and development of T2DM and insulin resistance.

Abstract:In recent years,the outbreak and prevalence of respiratory infectious diseases in the world seriously endanger
human health,among which the respiratory infectious diseases caused by viral infection account for a large proportion. The
use of vaccines and common antiviral drugs is an effective way to fight viral infection,but there are also problems such as lag
and drug resistance. Monoclonal antibodies against respiratory viral infections provide a new strategy for clinical
treatment. This paper reviews the development of monoclonal antibody against respiratory virus and its application in
respiratory viral infectious diseases.

ObjectiveTo study possible mechanism through investigating the pathological and ultrastructural characters of secondary injury to perihematoma in intracerebral haemorrhage (ICH) rats.MethodsSprague Dawley male rats were subjected to ICH models. They were randomly divided into test group and control group. The rats in the test group were divided into 7 subgroups at 1h,3h,12h,24h,48h,72h and 7d after ICH; while those in control group were divided into 3 subgroups at 3h,24h,72h after saline injection. Each subgroup contained 5 rats. 2 rats from each group were stained by 2% triphenyltetrazolium chloride(TTC) to observe the pathological change.3 rats were picked up from each group to do optical microscope and electric microscope investigation on perihematoma tissue and ipsilateral cortex.ResultsHematoma tissue was demonstrated as black brown by TTC staining, no white infarcted area was detected around hematoma. In addition, there was a transitional zone between hematoma and normal tissue under microscopy; the involved tissue looked loose with varied edematous cells. Astrocytes appeared swollen and neural cells looked degenerated and necrosis. Meanwhile, capillary hyperplasia around hematoma with foot plate swollen were detected, no remarkable neural cells change was observed. 24 h after blood injection, astrocytes started to swell, part of them became degenerated and necrosis. Neural cells appeared mild degenerated and blood brain barrier were destroyed. 72 h after ICH, astrocytes showed highly swollen with neural cells degenerated.ConclusionSecondary injury to perihematoma has been identified and the pathological and ultrastructural changes have been observed.

Aim Toinvestigatetheroleofbrain-de-rived neurotrophic factor(BDNF)-tyrosine receptor ki-nase B (trkB ) signaling pathway in the therapeutic effects of ketamine on diabetic neuropathic pain.Meth-ods Forty-eightWistarrats,aged3months,weighing 200~250 g,were equally randomized into 4 groups(n=12 ):control group (C group ), saline group (S group),ketamine group (K group)and ketamine +ANA-12 group (KA group ).Rats in S,K and KA groups were intraperitoneally injected with a single of streptozotocin(STZ)65 mg·kg-1 to construct diabetic neuropathic pain model.After twenty-eight days,rats in S,K and KA groups were intraperitoneally injected with saline, ketamine 10 mg·kg-1 and ketamine 10 mg·kg-1 +ANA-12 0. 5 mg·kg-1 for consecutive 7 days, respectively. On the 8th day, mechanical withdrawal threshold(MWT)of rats was measured.Af-ter that,the rats were immediately sacrificed,and dor-sal ganglion of lumbar spine and prefrontal cortex (PFC)were harvested for measuring BDNF,p-trkB/trkB,synaptophysin and spine density by Western blot andglogistaining.Results ComparedwithCgroup, rats in S group significantly decreased MWT,BDNF, p-trkB/trkB,synaptophysin and spine density in dorsal ganglion and PFC (P <0. 05 ).Compared with S group,rats in K group showed a significant increase of MWT,BDNF,p-trkB/trkB,synaptophysin and spine density in the all observed regions(P<0. 05 ).On the contrary,rats in KA group showed a significant de-crease of MWT and BDNF,p-trkB/trkB,synaptophys-in and spine density as compared with K group in all regions(P<0. 05 ).Furthermore,BDNF was positive-ly correlated with spine density in all regions (P <0.05).Conclusion BDNF-trkBsignalingpathway mediates ketamine-induced therapeutic effects in dia-betic neuropathic pain.

Objective To investigate the prevalence of tumor necrosis factor-?(TNF-?)promoter polymorphisms(at position-308 or-238)in patients with nonalcoholic fatty liver disease(NAFLD),and to explore the relationship between TNF-? promoter polymorphisms and obesity and the insulin resis tance(IR)in those patients.Methods Metabolic variables were measured in 117 patients with NAFLD, among them 60 were obesity and 57 were non-obesity.Genotype of TNF-? promoter were determined by PCR-RFLP.Plasma TNF-? level was measured by ELISA.Indexes of IR and insulin secretion were determined using the homeostasis model assessment method.One hundred and twenty normal subjects who were matched for age and sex served as control.Results The G→A mutation of the-238 TNF-? polymorphism was significantly higher in patients with NAFLD versus controls(29.9% vs.15.8%, P

Objective:To evaluate the effectiveness of conducting multiple arthroplasty to treat multiple joints disease in terms of quality of life ( QOL) and function improvement.Methods:We compared our results with the reported results of single and dual arthroplasty to see if there is any improvement in QOL, functional scores or complications.In this study, 13 patients admitted to Department of Adult Reconstruc-tive Surgery, Beijing Jishuitan hospital from 2005 to 2009 were included.Questionnaires SF-36 were used to evaluate the QOL.Harris hip score, American Knee Society Score ( KSS) were used to evaluate the joint function.The patients were evaluated before surgery to the latest follow up.Results:SF-36 has changed as follow:physical function 4.17 ±14.43→65.83 ±24.76, role physical 25.00 ±26.11→60.42 ±45.8, bodily pain 23.83 ±21.41→76.88 ±20.89, general health 53.33 ±33.87→76.67 ± 14.67, vitality 50.42 ±17.25→71.67 ±16.28, social functioning 29.17 ±33.50→73.96 ±33.90, role emotional 22.08 ±35.61→77.77 ±41.03, mental health 53.33 ±25.70→82.67 ±14.41, which indicated that they all improved greatly after the surgery ( P <0.05 ) .Harris score increased from 37.68 ±14.71 before the surgery to 83.36 ±13.54 after the surgery.KSS has also showed sharp im-provement (P<0.001) in both clinical score (42.52 ±23.83→77.74 ±20.67) and function score (-2.61 ±22.56→65.65 ±30.76).Conclusion:Multiple arthroplasty is one of the most effective me-thods which can markedly improve the quality of life in patients with multiple joints disease.But compli-cations are common and joint functions are relatively poor.
