The effect of insulin treatment on fatty liver was investigated in diabetic mice fed with high-fat diet.C57 BL/6J mice were fed with high fat diet for 12 weeks,and then treated with Glargine for 4 weeks.The results showed that during intraperitoneal glucose tolerance test,blood glucose,serum total cholesterol and triglyceride(TG) were significantly lower in insulin-treated high fat group than those in untreated ones(P<0.05).The hepatic histology showed minimal or barely visible fat in hepmic cells along with TG content in liver decreasing by 20.71%. The results suggest that insulin ameliorates hepatic intracellular lipid accumulation induced by high fat diet.

Objective To review the effect of exposed and buried Kirschner wire fixation of lateral humeral condyle fracture in children.Methods Randomized control trials (RCTs) about exposed versus buried Kirschner wire fixation of lateral humeral condyle fracture in children were identified through electronic search using the Cochrane Collaboration search strategies and manual search.Electronic database included Cochrane Library,Medline,PubMed,CBM,VIP,CNKI,Wanfang database and other Chinese and English database.Manual research included related journals and conference proceedings.Quality analysis of the included literatures was performed using the methodological index for non-randomized studies (MINORS).RevMan 5.3 software was used for Meta analysis.Results Four studies involving exposed Kirschner in 150 cases and buried Kirschner in 351 cases were included.The two techniques were similar with respect to postoperative infection (OR =1.10,95％ CI 0.52 ～ 2.33,P ＞ 0.05),superficial infection (OR =1.45,95 ％ CI 0.66 ～ 3.18,P ＞ 0.05),reoperation rate (OR =2.29,95％CI 0.51 ～ 10.25,P ＞0.05),delayed union rate (OR =1.57,95％ CI 0.76 ～ 3.21,P ＞0.05) and total complications (OR =1.57,95％ CI 0.76 ～ 3.21,P ＞ 0.05).However,Kirschner wire exposure shortened the time of pulling out Kirschner wire (MD =-13.28,95％ CI-16.42 ～-10.14,P ＜0.05).Conclusion Applied for lateral humeral condyle fracture in children,exposed versus buried Kirschner wire fixation results in short Kirschner wire stabilization time that avoids local anesthetic and cost while pulling out Kirschner wire in the late stage.

OBJECTIVETo investigate the protective effect of hypothermia combined with dexamethasone on spermatogenesis and the expression of intercellular adhesion molecule 1 (ICAM1) after testicular torsion-detorsion.

METHODSWe made unilateral testicular torsion models in 100 pubertal male Sprague-Dawley rats by 720 degree torsion of the left testis and then randomly divided them into four groups of equal number to be treated with normal temperature + physiological saline (group A), hypothermia + physiological saline (group B), normal temperature + dexamethasone (group C), and hypothermia + dexamethasone (group D). After 48 hours, we collected the testes, observed pathological changes of the testicular tissue by HE staining under the light microscope, detected the apoptosis of spermatogenic cells by TUNEL, and determined the expression of ICAM1 by Western blot.

RESULTSHE staining showed different degrees of testicular tissue injury in the four groups of rats, most obvious in group A, but mild in the other three. The ICAM1 protein expression was significantly higher in group A (0.68 +/-0. 03) than in B (0. 49 +/- 0. 06, P <0. 05) , C (0. 46 +/- 0. 09, P < 0.05) , and D (0.17 +/- 0.08, P <0.01). The nuclei were deep brown or brown. Lots of apoptotic spermatogenic cells were seen in the torsion testis of group A, with a significantly higher apoptosis index ( [33. 13 +/- 3.21 ]%) than in B ( [ 17. 12 +/-5.23 ]%, P < 0.05), C ([14.13 +/- 2.03]%, P <0.05), and D ([9.05 +/- 1.03]%, P <0.01).

CONCLUSIONHypothermia combined with dexamethasone can protect the testis from injury as well as the reproductive function of the testis after testicular torsion-detorsion and reduce the expression of ICAM1.

Objective To investigate the effect of early insulin therapy on NF-KB pathway and inflammatory cytokine responses in fiver of diabetic rat.Methods NF-KB p65 DNA binding was assayed with ELISA-based assay kit,cytokine gene expressions were quantified with real-time PCR and phosphoenolpyruvate carboxykinase(PEPCK),NF-KB and inhibitor KB(IKBα)protein levels wlere assayed with Westem blot.Results Compared with control,hepatic PEPCK protein level in the untreated diabetic rat increased by 40%.Early insulin and gliclazide treatment normalized PEPCK protein level.The abundance of IKBα protein was significantly decreased and nuclear NF-KB p65 DNA binding activity was incteased in untreated diabetic rats.IKBot protein content increased and NF-KB p65 DNA binding decreased during early intervention treatment.mRNAs encoding IL-1β and TNFα were increased,which were reduced to normal levels after insulin and gliclazide treatment.Conclusions It is suggested that early insulin treatment inhibits NF-KB activity and inflammatory cytokine responses in fiver that are involved in the aniefioration of insulin resistance in diabetic rats.Such results misht be due to indirect antiinflammatory effects of insulin thus relieving glucotoxicity and lipotoxicity in pefipherM tissues.

Objectives To investigate the clinical features,prognosis and risk factors of patients with cryptococcal meningitis.Methods Totally 146 patients with cryptococcal meningitis who were hospitalized in Huashan Hospital from January 2000 to December 2006 were enrolled in this study.The clinical data including diagnosis and misdiagnosis,experimental and etiology tests,treat- ments and prognosis from all the patients were analyzed retrospectively.Results Among the 146 patients enrolled in the study,78 patients(53.4%)had concomitant diseases.The misdiagnosis rate of all patients was 72.6%(106/146).The positive rate of cerebrospinal fluid(CSF)India ink smear was 59.6%(87/106),while 43.2%(63/146)cases of cryptococcus neoformans culture in CSF was positive.The positive rate of Latex agglutination test(LAT)was 91.7%(134/146)in CSF among all patients.The treatments were as follows:combination of Amphotericin B(AmpB)or its lipid formula- tions with flucytosine(5-FC)(98 cases),including combination with Fluconazole initally(62 cases), single therapy of Fluconazole(13 cases).Ommaya implanted for lateral cerebral ventricle drainage(53 cases)and AmpB intrathecal injection(53 cases).The average dose of AmpB is 3.06 g.The course of treatment lasted from 12 weeks to 20 months.There were 104 patients(71.2%)cured,27(18.5%) improved,15(10.3%)died and 34(23.3%)relapsed.Conclusions High misdiagnosis rate is common in patients with cryptococcal meningitis.Immunodeficiency is the major risk factor for cryp- tococcal meningitis.CSF LAT is the most sensitive diagnostic test.Early diagnosis,combination of AmpB with 5-FC antifungal therapy and control of acute intracranial hypertension are the keys to im- prove prognosis of cryptococcal meningitis.

Objective To investigate the expression of Toll-like receptor 3 (TLR3) on dendritic cells(DCs) derived from peripheral blood mononuclear cells(PBMCs) of chronic hepatitis B(CHB) patients and to explore the mechanism of sustained infection of hepatitis B virus (HBV). Methods Twenty CHB patients were randomly screened in the study,and ten healthy persons were recruited as controls.The monocytes isolated from peripheral blood of candidates were incubated with recombinant human granuloeyte macrophage colony-stimulating factor (rhGM-CSF) and rhIL-4 to induce the DCs generation and proliferation.Then the phenotype of DCs was identified by micro- scope.The expressions of the phenotypes[histocompatibility leukocyte antigen(HLA)-DR,CD80, CD86,CD83]of immature and mature DCs were measured by flow cytometer.Furthermore,the ex- pression of TLR3 on mature DCs(mDC) and immature DCs(imDC) was determined by flow cytometry and Western blot analysis respectively.Results As for healthy volunteers,the expressions of CD80, CD86,HLA-DR and CD83 on DCs at the 7th day,which were(82.35?8.67)%,(79.61?10.08)%, (92.79?8.48)% and (83.76?5.47)% respectively,were significantly higher than those at the 5th day which were(28.31?8.79) %,(31.17?11.23)%,(27.61?10.28)% and (23.46?11.53)% respec- tively(P0.05).The expression of TLR3 on imDC was significantly higher than that on mDC at control group (P0.05).And the expression of TLR3 on imDC in CHB patients group was significantly lower than that of control group(P
