Abstract The variation of functional protein C (PC), the activities of total plas. minogen activator and antithrombin Ⅲ (ATⅢ) were observed in canine SMAO shock. The results indicated that under normal conditions, compared with into-pulmonary blood (IPB), in out-pulmonary blood (OPB) the functional PC increased and ATⅢ activity decreased significantly (P

Aim To study the regulating effect of Tongxinluo on HIF-1α,VEGF that Generated by the Human brain microvascular endothelial cells induced by β-amyloid 1-42.Methods Human brain microvascular endothelial cells were pre-incubated for 4h by Tongxinluo, then injured by β-amyloid 1-42.VEGF protein and HIF-1α were detected by Western blot.Result In the Aβ treated Human brain microvascular endothelial cells,viable cells decreased.The expression of VEGF was Reduced, and HIF-1α elevated. After the cells were treated with Tongxinluo, all the above indexes were improved.Conclusion Tongxinluo can enhance the VEGF protein expressions by the HIF-1α and protect the Human brain microvascular endothelial cells.

For decades, coping has undergone intensive investigation through different theoretical lens. In this paper, three theoretical standings in coping research were proposed:namely,the process theory, the trait theory and the situation theory. Relevant research and measurements were introduced. In the end, different perspectives were reevaluated and implication for further research was discussed.

damage possibly by inhibiting the activation of NF-κB,accelerating the apoptosis of pancreatic ceils and reducing release of pancreatic enzyme.

Designed experiment teaching fits well with characteristic of naval hygiene training subjects on the sea.Attention should be paid to several key points including content selection,training plan design and teaching effect evaluation.It was proved that designed experiments enhanced the practical ability of the undergraduates and significantly improved the effect of naval hygiene training subjects.

Objective To probe into optimal delivered dose of 131I therapy in hyperthyroidism and influencing factors.Methods Data of 6374 patients with hyperthyroidism receiving 131I therapy were summarized and analyzed.The patients were differentiated into Graves group (GD) and multinodular toxic goiter group (NGD) after 131I therapy.To compare incidence of hypothyroidism between two groups after 131I therapy,partial correlations analysis was performed between delivered dose and other variables influencing factors among cured patients.Results After 131I therapy incidence of permanently hypothyroidismin patients with Graves' group was much higher than that in patients with multinodular toxic goiter group(17.01％,0.39％,Pearson x2 value =704.8,P ＜ 0.01).Delivered dose of 131I therapy related closely to thyroid size,with or without nodules and thyroid rigidity(r =0.469,0.484,0.553).Disposable cured rate of 131I therapy was higher than 63.99％.Conclusion 131I therapy is optimal to multinodular toxic goiter.Delivered dose of 131I therapy will be increased for patients with bigger and stiff mass for therapeutic effects.

Objective To investigate the anti-erythropoietin antibody level and its clinical significance in maintenance dialysis patients. Methods Eighty maintenance hemodialysis (HD) and 30 peritoneal dialysis (PD) patients were enrolled in the study. Serum anti-erythropoietin antibody levels of above 110 dialysis patients were measured by ELISA. Immunoreactive parathyroid hormone (iPTH), Scr, BUN, Hb, and CRP were determined by conventional methods at the same time. Correlations among these indexes were examined. Results The anti-erythropoietin antibody levels of the dialysis patients were significantly higher than those of healthy people (P＜0.05), but no significant difference was found between HD patients and PD patients. There were no significant differences of anti-erythropoietin antibody, Hb, BUN, Scr, iPTH and CRP among different primary diseases. Hb was negatively correlated with anti-erythropoietin antibody and CRP (r=-0.56, -0.20,P ＜0.05), but was not correlated with BUN, Scr, iPTH. There was no correlation of antierythropoietin antibody with BUN, Scr, CRP and iPTH. One patient receiving recombinant human erythropoietin (rHuEPO) treatment with anti-erythropoietin antibody 43.63 U/L developed pure red cell aplasia diagnosed by marrow biopsy. Conclusions The anti-erythropoietin antibody levels of the dialysis patients are significantly higher as compared to healthy people, but are not significantly different between HD and PD patients. Anti-erythropoietin antibody is not correlated with BUN, Scr,iPTH and CRP. Hb is negatively correlated with anti-erythropoietin antibody and CRP. The rHuEPO can induce the anti-erythropoietin antibody leading to pure red cell aplasia in dialysis patients.

Objective To screen out single chain variable fragment antibody (scFv)specific to vascular cell adhesion mole‐cule 1(Vcam‐1)from phage recombinant antibody library ,and to evaluate its activity and compare its activity with full‐length monoclonal antibody.Methods Amplification of Vcam‐1 was performed by PCR and Vcam‐1 gene plasmid was transferred into eukaryotic cells to express Vcam‐1 antigen protein.Immune cuvette was coated with purified Vcam‐1 antigen ,and the positive clones were screened out by 4 rounds of “adhesion‐elution‐proliferation” process with gradually increasing pressure.The posi‐tive clones were tested by ELISA method and high titer clones were chosen for gene sequencing.Then the high‐titer clones were transferred into E.coli ,and the clone with the highest expression was regarded as the final requisite one.Competent cells were infected by the final requisite clone and scFv was expressed.After purification ,the activity of scFv was tested by ELISA and its affinity was evaluated.Results Molecular weight of Vcam‐1 antigen protein was 85-90 kD.Positive clones were screened out by taking Vcam‐1 protein as the antigen ,and 9 high titer clones were obtained by single phage ELISA.Gene sequencing of these clones was carried out and 3 sequences were obtained ,1 of which got the highest expression.Molecular weight of the expressed scFv was about 30 kD.The scFv got high affinity to Vcam‐1 antigen according to ELISA ,in spite of its lower activity than full‐length monoclonal antibody.Conclusion scFv antibody specific to Vcam‐1 was successfully obtained from phage display librar‐y ,which laid the foundation of subsequent in vivo diagnosis and therapy.

This paper introduces the perioperative nursing of 47 patients undergoing intraperitoneal parastomal hernia repair.After the surgery,two cases suffered from incision infection and two cases with subcutaneous hydrops.Three patients suffered from chronic pain or foreign bodies sensation,which disappeared at 3-6 months later.No recurrence occurred at 6-24 months after the surgery.It is suggested that the key points of perioperative nursing were careful preoperative symptom care and bowel preparation,as well as postoperative observation and correct discharge instruction.
