Aim To observe the expression of migration inhibitory factor (MIF) in the enteric neurons,and to explore the nervous regulation on MIF activity in experimental colitis.Methods Colitis was induced in sensitized rat and mouse by 2,4-dinitrochlorobenzene(DNCB)enema.MIF activity was measured both in the mesentery lymphocyte(by MTT)and in the enteric neurons(by immunofluorescence double staining).6-OHDA was intraperitonealy (ip) administered to mouse before DNCB treatment.Norepinephrine(NE) was added to lymphocyte culture in vitro during MIF preparation.Results The expression of MIF protein in enteric neuron was increased in DNCB-induced colitis in rat.ip 6-OHDA in colitis mouse(38～150 mg?kg-1) resulted in a further increase of MIF activity than ip vehicle in colitis mouse (P

AIM: In order to explore the pathogenesis of ulcerative colitis (UC), an experimental colitis in mouse was induced by the hapten dinitrochlorobenzene (DNCB), and the activity of leukocyte migration inhibitory factor (LMIF) was measured at the same time. METHODS: 67 BALB/c mice were randomly divided into control (60% ethanol) and DNCB groups. After they were sensitized by smearing 3.3% DNCB on the abdominal skin, they were challenged with DNCB at concentration of 0.1%, 0.2% and 0.4% respectively by instillation once a day. The weight, stool viscosity and hematochezia were observed and accumulated as disease active index (DAI) score. The pathological changes in colon tissue were judged macropathologically and by means of microscope. LMIF activity was determined by the absorbance (A) of migrated leukocytes. RESULTS: Compared to control group, the increases in DAI accumulate score, pathologic score, and LMIF activity in DNCB groups were observed. CONCLUSION: Mouse colitis was induced by DNCB, which was accompanied by an increase in LMIF activity. [

Objective To evaluate the surgical efficacy of benign tumor of liver in the caudate lobe.Methods The clinical data of 112 patients with benign tumor of liver in the caudate lobe who were admitted to the Eastern Hepatobiliary Surgery Hospital from January 2003 to April 2014 were retrospectively analyzed.The leftsided approach,right-sided approach,bilateral approach,central anterior approach and retrograde caudate lobectomy were selected according to the location and size of the tumor.All the patients were followed up by outpatient examination and telephone interview up to October 2014.Results Of all the 112 patients who received complete resection of tumor,33 patients received caudate lobectomy (22 by bilateral approach,11 by left-sided approach),28 received left hemihepatectomy + caudate lobectomy (by left-sided approach),21 received mesohepatectomy + caudate lobectomy (by central anterior approach),19 received partial right hepatectomy + caudate lobectomy (by right-sided approach),11 received right hemihepatectomy + candate lobectomy (9 by right-sided approach,2 by retrograde caudate lobectomy).During the operation,72 patients received vascular inflow occlusion,29 received vascular inflow occlusion combined with hepatic veins occlusion,6 received total hepatic vascular exclusion and 5 did not receive vascular inflow occlusion.The operation time,mean time of vascular inflow occlusion,mean volume of intraoperative blood loss,cases of blood transfusion,mean volume of blood transfusion and duration of postoperative hospital stay were (192 ± 69)minutes,28 minutes (range,0-94 minutes),590 mL (range,100-12 000 mL),68,600 mL (range,200-10 000mL) and (8.2 ± 2.7) days,respectively.Thirty-one patients had postoperative complications,including 21 with bile leakage,7 with medium and above volume of pleural effusion,2 with postoperative bleeding and 1 with hepatic failure.The complications were cured after symptomatic treatment.No patient died perioperatively.All the 112 patients were followed up for a median time of 12 months (range,6-24 months).All patients were survived well and without tumor recurrence during the follow-up.Conclusions Surgical treatment is an effective method for benign tumor of liver in the caudate lobe,with the good recovery of patients and definitive surgical efficacy.The key factors of surgical treatment include strictly following operative indication,rationally optimizing surgical approach,suitably selecting vascular inflow occlusion and the accurate operation.

Antheraea pernyi nucleopolyhedrovirus (ApNPV) PstI-B and C fragments were cloned and sequenced. ApNPV PstI-B was 7406 bp long, contained seven open reading frames (orfs)/genes, including p87, he65, pnk/pnl, odv-ec43 and Orgyia pseudotsugata multicapsid nucleopolyhedrovirus (OpMNPV) orf107,orf108 homologue on either strands of genomic DNA. ApNPV PstI-C was 6663 bp long, contained eleven orfs/genes, including pk-1, orf1629, polh, lef-2, ptp-2, ctl-1, ptp-1 and OpMNPV orf5, orf7, orf8, orf1 1 homologue on either strands of genomic DNA. Among the eighteen baculovirus genes identification, he65 and orf1629 were two diverse genes, while polh and lef-2 were two conserved genes. ApNPV was the third baculovirus found to contain pnk/pnl gene, the fourth baculovirus found to contain both ptp-1 and ptp-2 gene.

The levels of low-density lipoprotein(LDL)glycation from control group,diabetic HbA1C < 7.0%,and HbA1C>7.0% groups were(17.7±2.31),(34.29±5.73),and(48.79±7.82)Glycogroups/LDL by fluorimetry.The LDL binding to its receptor in three groups were(37.65±5.20),(27.36±4.34),and(15.07± 2.23)ng/mg cell protein measured by enzyme-linked immunoreceptor assay.The glycated levels in two diabetic groups were higher than that in control group,and higher in HbA1C>7.0% group than in HbA1C<7.0% group(all P< 0.01).The results of LDL binding capacity to its receptor were just the opposite.

Objective:To investigate the role of transcription factor SP1 decoy oligodeoxynucleotides(ODN) on expression of ? Gal in SV-40-PED cells.Methods:Immortalized porcine aortic endothelial cells of the PED line were cultured and transfected with ?1,3galactosyltransferase(?1,3GT) specific decoy ODN.Cells transfected with mismatch ODN was used as negative controls.Twenty-six hours later the cells were collected.The expression of ? Gal was determined with fluorescence microscope and Western blot.The expression of ?1,3GT mRNA was examined by RT-PCR.Results:Fluorescence microscopy observed the decreased fluorescence of ? Gal after decoy ODN transfection.Western blot showed that the average absorbance of the PED cells transfected with decoy ODNs was(48.2?0.9).It is 52.6% of the mock group(P0.05).Conclusion:?1,3GT gene reduce actually occurs following transfection of decoy ODN.Porcine endothelial cells can be the targets of decoy ODN.

Objective To observe the therapeutic effect of manipulative reduction combined with small-splint fixation for the treatment of Barton's fracture.Methods The apposition state,time for swelling disappearance,time for pain relief,and the score evaluated with Gartland-Werley(GW) criteria modified by Sarmiento were observed for the evaluation of therapeutic effect on Barton's fracture patients.Results After manipulative reduction combined with small-splint fixation,the apposition state was good,and volar tilting angle and ulnar inclination were improved in the patients.Time for the disappearance of swelling on the back of hand ranged from 4 to 14 days,averaged 6.0?1.6 days.Time for pain relief ranged from 3 to 10 days,averaged 6.4?1.6 days.Time for the union of fracture ranged from 30 to 60 days,averaged 35.4?8.3 days.The mean modified GW score was 3.6?2.5,and the score was excellent in 29 patients and good in 41 patients.Conclusion Manipulative reduction combined with small-splint fixation is effective and practical for the treatment of Barton's fracture.
