Objective To discuss the efficacy and relative factors that affect the sequential therapy of invasive and non-invasive mechanical ventilation in treating severe respiratory failure.Methods We analyzed the clinical data of the patient who was hospitalized in Respiratory Department of the Sixth Hospital of Luohe on 3th February 2008.Results The patient received invasive mechanical ventilation for 4 days,then changed to mask non-invasive positive pressure ventilation for 10 days,while receiving comprehensive treatment of anti-infection and bronchial expansion,etc.Then the patient was recovered.Conclusion The sequential therapy of invasive and non-invasive mechanical ventilation in treating severe respiratory failure is effective.The efficacy depends on the optimum converting time between invasive and non-invasive mechanical ventilation,the choice of ventilator and the patient′s compliance.

One hundred and five patients with non-ST segment elevation acute coronary syndrome were followed up for 1 year.They were assigned to the event group or non-event group according to the presence of endpoint events(cardiac death and nonfatM myocardial infarction).B-type natriuretic peptide level was measured at 30 days and 1 year and compared between the two groups.The results showed that the level of B-type natriuretic peptide was higher in the event group[(235±107)μg/L vs(154±49)μg/L at 30 days;(259±100)μg/L vs(143±57)μg/L at 1 year].Thus,B-type natriuretic peptide is an important prognostic factor for patients with non-ST segment elevation acute coronary syndrome.

Objective To evaluate the value of the four kinds of diagnostic method in acquired immune deficiency syndrome (AIDS) infection complicating tuberculosis (TB) .Methods 52 cases of human immunodeficiency virus (HIV) infection complica‐ting TB were taken as the observation group and 100 cases of TB without complicating HIV infection were taken as the control group .The two groups were performed the PPD test ,sputum Mycobacterium tuberculosis culture ,tuberculosis antibody and inter‐feron gamma release assay(IGRA) for conducting the diagnosis .Results The positive rate of the PPD test ,sputum Mycobacterium tuberculosis culture and tuberculosis antibody in the control group were significantly higher than those in the observation group ,the differences were statistically significant (P<0 .01);the positive rate of the IGRA in the observation group was obviously higher than that of the PPD test ,sputum Mycobacterium tuberculosis culture and tuberculosis antibody ,the differences had statistical sig‐nificance (P<0 .01) .The negative occurrence rate of the IGRA in the observation group treated by the antiretroviral therapy was obviously higher than the positive rate ,the difference was statistically significant (P<0 .05) .Conclusion The IGRA may be a sen‐sitive method for diagnosing HIV infection complicating TB and the antiretroviral therapy may have a certain impact on the results .

【Objective】To observe the regulation of acupuncture on experimental insulin resistance in rats and to investigate the influence of diet during the acupuncturing.【Methods】Forty rats were equally randomized into blank group,model 1 group,model 2 group,acupuncture 1 group and acupuncture 2 group.Rat models with insulin resistance were induced by feeding forage of high fat,sugar and salt.After the models were induced successfully,blank group was still fed with normal forage,model 1 group still with forage of high fat,sugar and salt,model 2 group with normal forage instead,acupuncture 1 group still with forage of high fat,sugar and salt for 2 weeks and acupuncture 2 group with normal forage instead.Meanwhile,acupuncture 1 and 2 groups received acupuncture once a day.The changes of fasting plasma glucose(FPG),plasma insulin(INS),insulin sensitivity index(ISI),serum Cpeptide(C-P) and the ratio of INS and C-P were observed after treatment.【Results】FPG,INS,C-P and INS/C-P were increased and ISI decreased in model 1 group as compared with the blank group(P

OBJECTIVE:To study the preventive and therapeutic actions of L-arginine on pulmonary hypertension induced by high pulmonary blood flow volume.METHODS:Male SD rats were randomly divided into control group(n=6),shunt group (n=7) and shunt+L-arginine group(n=8).Abdominal aorta-inferior vena cava shunt was performed to make the blood flow from left to right,11 weeks later,mPAP was detected with right cardiac catheter;the structure of pulmonary vessels and expression of PCNA of smooth muscle cells were observed.RESULTS:The mPAP of shunt group was obviously higher than that of control(P

Objective To clone and express the cell signaling protein 14-3-3 gene from Toxoplasma gondii RH strain. Methods Toxoplasma RH strain tachyzoites, which maintained by mouse passage, were harvested from ascites of mice and genomic DNA was prepared. A pair of primers were designed and synthesized based on the sequence of Toxo 14-3-3 cDNA. A specific fragment of Toxo 14-3-3 gene was obtained by RT-PCR amplification from Toxoplasma genomic DNA. The PCR products were ligated to pGEM-T. The EcoRI / Xho I restricted fragments, confirmed by PCR and EcoRI / XhoI digestion, were cloned into expression vector pET28a and the recombinants were transformd into E.coli BL21. Fusion expression was induced by isopropyl-beta-D-thiogalactoside (IPTG) and confirmed by Western blotting with rabbit anti-Toxoplasma sera. Results The molecular size of Toxo 14-3-3 was 803 bp, which is highly homologous to the previous report cloned from the parasites of intestinal epithelial stage in cat. High expression was obtained in pET28a/ Toxo 14-3-3/E.coli BL21 when confirmed by Western blotting. Conclusion The recombinant construction of Toxo 14-3-3 was generated and expression was induced.

Objective To explore the outcomes of kidney transplant recipients who developed urinary and male genital cancers after transplantation. Methods Data of 31 kidney transplant recipients developed de novo urinary and male genital cancer were compared with data of 31 patients in general population with the same age and same tumor stage. Results Compared with the general population, the overall survival was significantly worse in the transplant recipients (P=0. 02) , 5-year survival rates for each group were 50% vs 68%. Multivariate analyses demonstrated cancer stage to be a negative risk factor for survival for transplant recipients with de novo urinary and male genital cancer, and surgery and functioning graft to be the positive survival predictors. Conclusions Transplant recipients experience worse outcomes than the general population from urinary and male genital cancers. Cancers in transplant recipients are more biologically aggressive at the time of diagnosis.
