Objective We compared the effect of three anesthetic procedures on the establishment of and recovery effect on the young minipig models of skull defect,and explore an optimal anesthetic procedure for long-lasting surgical experiment in minipigs.Methods Thirty 3-month old Guizhou minipigs (male∶female=1∶1) were randomly divided into three groups,10 in each group.The group A was given with midazolam and ketamine i.p.,the group B received lumianning II i.p.,and the group C received midazolam combined with ketamine and lumianning II i.p.The induction time of anesthesia,the first anesthesia maintenance time,the first anesthesia maintenance period after additional use of anesthetics,the second time anesthesia maintenance period after additional use of anesthetics,the recovery period,the number of times of additional intraoperative use of anesthetics,cumulative amount of anesthetics used,and the adverse reaction and mortality rates of the animals after anesthesia were observed and analyzed.Results The anesthesia induction time in the group B was significantly longer than that in the groups A and C (P<0.05 for both).The anesthesia maintenance time and the anesthesia maintenance after first and second additional use of anesthetics in the groups A were significantly longer than those of the groups A and B (P<0.05 for both).The recovery periods in groups A and C were shorter than that of the group B (P<0.05 for both).The number of times of additional intraoperative use of anesthetics,the total dose of anesthetics,the adverse reaction and mortality rates in the group C were significantly lower than those of the groups A and B (P<0.05 for both).Conclusions The combination of midazolam with ketamine and lumianning II is a simple,easy to control the anesthesia depth,and a safe method to anesthetize young minipigs in long-lasting surgical experiment.

Objective To compare the QTc and QTcd between type 2 diabetic and non-diabetic patients with post-myocardial infarction (post-MI) ,and to compare the QTcd in type 2 diabetic patients with post-MI treated with insulin,sulfonylurea,mefformin,or diet alone. Methods We measured the QTc and QTcd through simultaneous 12-lead Electrocardiogram in 138 post-MI patients,including 70 type 2 diabetic (of which,23 were assigned to re-ceive insulin,20 glipizide,16 mefformin,11 diet control) and 68 non-diabetic patients. Result Compared with post-MI patients without diabetes,those with type 2 diabetes had significantly higher QTc [(377.2±24.3) ms vs (342.9±27.5)ms,t=7.79,P<0.01] and QTcd [(48.8±19.7)ms vs (40.3±26.6)ms,t=2.14,P<0.05]. There were no significant difference between the mefformin group and the diet control group (P>0.05). The QTc and QTcd in the insulin group were significantly higher than those in the other three group s(P<0.05),and the QTc and QTcd in the glipizide group were higher than those in the mefformin group or diet control group(P<0.05,and P<0.01,respectively). Conclusion Type 2 diabetes is associated with an additional increase in the QTcd in post-MI patients,suggesting higher mortality risk in post-MI patients with type 2 diabetes. Insulin and glipizide may in-crease the QTc and QTcd in post-MI patients with diabetes. These effects were more significant in the insulin therapy group.

Objective To explore the attentional biases in individuals with different types of obsessivecompulsive symptom and the correlations between the attentional bias of high obsessive compulsive symptom (HOC) and symptoms. Methods 22 individuals with HOC and 38 individuals with low obsessive compulsive (LOC) symptom completed the Chinese Emotional Stroop task that assessed the attentional bias. Comparisons were made between HOC and LOC and in different types of HOC, and the correlations between the attentional bias of HOC and symptom severity scores were searched for. Results The comparison between HOC and LOC on the reaction time of neutral, negative and disgust-related words were not significant. The contamination/washing subtype in HOC showed faster reaction time on negative and disgust-related words compared to that of neutral words,and its attentional bias exhibited significant correlation with symptom severity scores( r= -0. 648, P=0. 031 ). Conclusion Such information point out the contamination/washing subtype may have a different neural mechanism compared to the other subtypes of OCD.

AIM:To obtain the light chain region(VL) and heavy chain region(VH) genes from the hybridoma cell line and analyse their sequence for construction of the engineering antibody against hCD154. METHODS: In this research ,total RNA was extracted from the hybridoma cell line 7E8, which secretes McAb against hCD154, and subjected to reverse transcription. The VL gene and VH gene were amplified by PCR, cloned into puc18 vector and sequenced by Sanger's dideoxymediated chain-termination method. RESULTS: The VL cDNA of 7E8 McAb consists of 341 bp encoding 113 amino acid residues. Compared with mouse Ig database, the VL region is in accord with the characterization of DNA sequence present in the mouse Ig Vk region , it belong to mouse V?2 light chain. The VH cDNA of 7E8 McAb consists of 354 bp encoding 118 amino acid residues. Compared with mouse Ig database, the VH region is in accord with the characterization of DNA sequence present in the mouse Ig VH region. CONCLUSION: The DNA squence analysis showed that the cloned genes code the light and heavy chain variable region of mouse respectively.

AIM:To express recombinant hCD154-GST fusion protein, to prepare anti-hCD154 monoclonal antibody, and to investigate the effect of anti-hCD154 monoclonal antibody on graft rejection. METHODS AND RESULTS: Total RNA was prepared from human peripheral blood mononuclear cell (PBMC) activated with 10ng/mL PMA and 1 ?g/mL PHA for 8h, the total RNA was reversetranscribed to cDNA. The entire coding region and a part of the 3'non-coding regions were amplified by PCR using a pair of primers designed and synthesized according to the sequence of human CD154 gene from gene bank. The amplified product, a 820bp DNA fragment was cloned into pGEX-4T-1 plasmid expressing glutathione S-transferase(GST). The cloned insert was identified by double digestion of the cloned pGEX-4T-1 plasmid with retriction enzymes BamHⅠand EcoRⅠ.The fusion protein expression plasmid of PGEX-4T-1/hCD154 was constructed, then transformed to E coli BL21. The human CD154-GST fusion protein expression was induced by IPTG in BL21. The expression of recombinant 26kD GST and 55kD human CD154-GST fusion protein were confirmed by SDS-PAGE. CONCLUSION: We have express the recombinant human CD154-GST fusion protein. The expressed hCD154-GST fusion protein will be used to prepare anti-hCD154 monoclonal antibody, to investigate the role of anti-CD154 monoclonal antibody on graft rejection.

Objective To assess the value of two-dimensional speckle tracking echocardiography (2D-STE) of predicting the acute response to cardiac resynchronization therapy (CRT) in patients with congestive heart failure. Methods Twenty-four patients with congestive heart failure scheduled for CRT were included. 2D-STE was performed within 7 days of implantation with device ON and OFF. Left ventricular (LV) dyssynchrony was defined as an interval ≥130 ms for the absolute difference in time to peak radial strain for the anteroseptal wall versus the posterior wall (T_(AS-POST)) with 2D-STE. Acute hemodynamic response was measured as LVdp/dt, and percentage change in LVdp/dt was used to classify responders (Δdp/dt%＞25%) and nonresponders (Δdp/dt%≤25%). Results Fifteen patients (62.50%) were classified as acute responders. Compared with nonresponders, the responders demonstrated significant increase of LV ejection fraction and reduction of TAS-POST after CRT-ON. T_(AS-POST)was the only determinants of Δdp/dt%＞25%. T_(AS-POST)≥130 ms prognosticated acute response to CRT with sensitivity of 86.24% and specificity of 70.38%. Conclusion CRT can immediately increase the LV systolic function and synchrony. 2D-STE is highly predictive for acute response to CRT.
