Utilized Sucrose as carbon source for fermentation production of pullulan, the yield were 60%. But when Starch-hydrolyzate as an alternative of sucrose as carbon source, the yield were less than 45%. utilize some carbon sources containing fructose, the yield tend upwards. We utilized isostarch-hydrolyzate as only carbon source and got an yield as similar as that sucrose did.

Objective To observe the clinical efficacy and safety of close-loop muscle relaxant injcction system (CLMRIS) combined with auditory evoked potentials index for monitoring in elderly patients during general anesthesia.Methods A total of 100 patients undergong abdominal operation with ASA Ⅰ-Ⅱ anesthesia in our hospital from February 2012 to October 2012 were selected.Patients were randomly divided into 2 groups:the traditional group (n=50) and the CLMRIS group (n=50).The traditional group was anaesthetized according to clinical experience,and the CLMRIS group was used with the muscle relaxant guided by the close-loop muscle relaxant injection system.The auditory evoked potential (AEP) index and the life index were observed,and the dose of muscle relaxant,the time of consciousness recovery,dynamic response rate during operation and the adverse reaction were recorded at the time points at entering the operating room,induction of anesthesia,tracheal intubation,incision,into the abdominal,exploration,closing abdomen,skin suture,consciousness recovery,tracheal extubation,out of room (T0-T10).Results The vital signs in all patients were stable.The dynamic response rate during operation was lower in the CLMRIS group than in the traditional group at each time points of T8-T10 (all P＜0.05).There was no increase in mean artery pressure (MAP) and heart rate in groups at the time points of T0-T1,T8-T10 (all P＞0.05).The time of tracheal intubation,tracheal extubation and consciousness recovery were shorter in the CLMRIS group than in the traditional group [(268±30.4) min vs.(172±23.7) min,(14±6.4) min us.(18±7.9) min,(8.8±2.9) min vs.(12.2±4.6) min,respectively,t=3.277,6.341,3.346,all P＜0.05].There were no significant differences in AEP index between groups at the time of T0 (P＞0.05),but at the time of T1,the AEP index was lower in CLMRIS group than in the traditional group (P＜0.05).Conclusions The application of close loop muscle relaxant injection system can improve the safety of general anesthesia in the elderly and reduce the incidence of postoperative residual paralysis.The CLMRIS combined with the auditory evoked potential for monitoring depth of anesthesia can prevent and reduce the incidence of intraoperative awareness,has a strong controllability in general anesthesia with smooth induction,and can reduce the dose of anesthetic drugs to achieve the best anesthetic effect.

Objective To investigate the feasibility of gene modification of peripheral blood derived endothelial progenitor cells(EPCs).Methods The rabbit mononuclear cells were collected from rabbit peripheral blood and cultured.The uptaking test of DiI-Ac-LDL was directly visualized with fluorescent microscopy,the immunofluorescence analysis was performed to detect the expression of surface marker.And the human tissue kallikrein(HTK)gene was amplified with PCR,and inserted into pEGFP-N3 vector.EPCs were transfected with the constructed plasmid by means of lipidosome,and the HTK-EGFP fused protein was visualized directly with fluorescent microscopy,and the expression of HTK was detected by RT-PCR and ELISA.Results After 5～6 days of culture,spindle-shaped attached cells clustered together,and cobblestone-like cell layer appeared after 15 days.Cells were positive of uptaking DiI-Ac-LDL and expressing vWF and CD133 related antigen.Plasmids were correctly formed and expressed in the rabbit EPCs.The fused protein had activity of both HTK and EGFP.Conclusion The HTK gene modified EPCs is potential in the treatment of artery injury and endothelial dysfunction.
