A case of traumatic delayed meningo-encephalocele suffered orbital fracture, but bony defects in frontal sinus had not been found on CT scanning. We treated the patient with surgery of intranasal endoscopy and repaired the skull base defect successfully during the first attempt. There was no recurrence in 10 months followed up. The leak site may not correlate with imaging in traumatic delayed meningo-encephalocele by comparing operative findings with the imaging estimate and endoscopy. Therefore, endoscopical approaching is effective in seeking and treatment.

Objective To construct the genetic engineered cell line which can continuously secrete human tumor necrosis factor ( hTNFα) in Chinese Hamster Ovary cells( CHO cells) ,and observe the change of its protein secretion function.Methods Constructed plas-mid which carries hTNFαgene expression through vector GV141.Selected stable transfection cell lines by G418 and transfection with lipo-fectamine.Identified its gene expression with Real-Time PCR,and identified its protein secretion by ELISA.Results GV141-hTNFαexpres-sion vectors were constructed successfully which were proved by sequence alignment.Real-Time PCR proved that it contained hTNFαgene in hTNFα/CHO cell line.ELIAS identification results showed that the cell lines can continuously secrete hTNFαwithin a certain cell propaga-tion.Conclusion The hTNFα/CHO cell line can continuously secrete human tumor necrosis factor within a certain cell propagation.

The relationship of insulin dosage during transition from continuous subcutaneous insulin infusion(CSII)to subcutaneous injections of premixed human insulin in 197 type 2 diabetic patients was analyzed. Positive correlation(r=0.60,P

Objective To investigate dexamethasone on airway inflammation and CD4+ CD25 + regulatory T cells (CD4+ CD25 +Tr) of asthmatic rats,and elucidate the possible mechanism of dexamethasone in treatment of asthma.Methods 30 Wistar rats were randomly divided into control group,asthma group and dexamethasone-treated group.Bronchoalveolar lavage fluid (BALF) was collected,and cytology study was conducted.The lung tissue was obtained and pathologic analysis was done through HE stain.Flow eytometry was used to detect the CD4+ CD25 +Tr ratio in PBMCs.Results Total cells number,the percentage of lymphocytes,neutrophils and eosinophils (Eos)in BALF of dexamethasone-treated group were lower than that of asthma group (P＜0.05,P＜0.01).Compared with the asthma group,less infiltration of inflammatory cells in lung tissues was observed in the dexamethasone-treated group.CD4+ CD25 + Tr of asthma group was lower than that of control and dexamethasone-treated group (P＜0.05).Conclusion Dexamethasone could suppress airway inflammation of asthmatic rats,which probably be due to increasing the number of CD4+ CD25 + Tr.

Objective To investigate the immunological mechanism of inhibitory effect of Danshen injection combined with dexamethasone(DXM) on asthmatic airway inflammation.Methods 50 Wistar rats were randomly divided into normal control(NC),asthma,Danshen,DXM and Danshen+DXM group.Cytology study of Bronchoalveolar lavage fluid(BALF) was conducted.Pathology of lung tissue was done through HE.Flow eytometry was used to detect CD4+CD25+ regulatory T Cells(CD4+CD25+ Treg) ratio in peripheral blood mononuclear cells(PBMCs).IL-4 and IL-5 levels in BALF were detected by ELISA.Results Total cells number,percentage of lymphocytes,neutrophils and eosinophils(Eos) in BALF of the three treated groups were lower than that in asthma group(P<0.05,P<0.01),particularly in Danshen+DXM group,which showed significant difference as compared with the other two treated groups(P<0.05).There was severe inflammation in lung tissue of asthma group,moderate inflammation in Danshen group and DXM group,and no inflammation of Danshen+DXM group.CD4+CD25+ Treg/CD4+ T ratio in the three treated groups were higher than that in asthma group,and the levels of IL-4 and IL-5 were lower than those in asthma group(P<0.05).In Dansben+DXM group,it showed significant difference on the change of CD4+CD25+ Treg,IL-4 and IL-5 as compared with other treated groups(P<0.05).Conclision Danshen injection combined with DXM could suppress airway inflammation in asthmatic rats,which may be through increasing the expression of CD4+CD25+ Treg,decreasing the levels of IL-4 and IL-5 and resuming the balance of Th1/Th2.

Objective To observe the effect of Jisheng injection(JI)in preserving isolated heart of mice.Methods Langendorff' s isolated -perfused mouse heart mod el was established.The isolated hearts were preserved in modified Eu-ro -Collins solution(MECS)and MECS with JI added for 3h,7.5h and8.5h respectively.Cardiac functio n,coronary flow and myocardial water -volume (MWV)were observed after 3h ,7.5h and 8.5h of preservation,heart reactivatio n(HR)rate,coronary flow,MWV and time for HR were also observed.Results After 3h of preservation and 20min,30min or 40min of reperfusion,cardiac function and coronary flow in three M ECS +JI groups and especially in that of large dose were improved as compared with t hose in MECS group;MWV in large -dose and moderate -dose groups was obvi-ously lower than that in MECS group(P

Objective To investigate the expression of CD40 and CD40L on the surface of peripheral blood mononuclear cells(PBMCs)in asthmatic rats and the effect of anti-CD40L McAb on cytokines of it.Methods Flow cytometry and RT-PCR were used to detect the expression of CD40 and CD40L of PBMCs ih asthmatic rats.After the PBMCs Was treated with anti.CIMOL McAb.ELISA was used to detect the levels of IL-4 and IFN-γin the supematants of cultured cells.Results Compared with the normal control group.the expression of CD40 and CD40L of PBMCs in asthImatic rats increased(P＜0.05).Compared with the untreated group,the level of IL-4 and the ratio of IL4/IFN-γ decreased after the PBMCs were treated with anti-CD40L McAb(P＜0.05).Conclusion The expression of CD40 and CD40L on the surface of PBMCs in asthmatic rats Was unregulated.Anti-CD40L Mcab Can decrease the level of IL-4 and the ratio of IL_4/IFN-γ.
