Objective Compare and analyze the serum proteomics data of healthy human and patients with bronchial asthma(both before and after ICS treatment).Then explore the possible pathogenesis and therapeutic targets.MethodsSelect 102 patients with chronic persistent asthma who were diagnosed and treated in our hospital during December 2015 to December 2016, and recruit 102 cases of healthy volunteers over the same period.The patients were treated with conventional ICS, after 8 weeks of treatment, compare and analyzethe serum proteomics data of healthy people and both patients with bronchial asthma (both before and after treatment).ResultsAfter treatment, patients with asthma still got poorer lung function than normal ones (P<0.05);at the same time, all of the serum HSP70, Eotaxin, MMP-9 of pre-treatment patients were higher than healthy individuals (P<0.05), although they had declined after treatment (P<0.05), but still higher than normal people(P<0.05).ConclusionHuman serum HSP70, Eotaxin, MMP-9 may not only be involved in the pathogenesis progress of asthma, but the mechanisms of treating asthma with ICS.

To observed the Clinical effect of ropivacaine (Rop) of different concentration used for analgesia of labor, and ex plore the ideal concentration and dosage. Methods: 45 case s of ASA Ⅰ-Ⅱ primiparae nearing labor were vandomly divided three groups rand omly (0.16% Rop group, 0.2% Rop group were assigned 15 cases). The analgesia, in which the cervical os had opened up to 2-3cm; the controlled group was not giv en the analgesia of labor. BP, SpO2, EKG, PETCO2, cerrical contraction , fetal cardiac sounds were monitored continuously in the perinatal analgesia pe riod. The analgesia effects were determined by giving a mark for pain by VAPS, motor nerve blockings were given amark by Bromage scale; Apgar scale were conduc ted 1-5 min after neonates were labored out. Results: The vital signs of three groups were stable in perinatal; the VAPS scale was lower s ignificantly in observed group than in controlled group; while the blocking freq uency and extent of motor nerve were highest from 0.2% Rop, which had light inhi bitory effect to cervical contraction, causing the dosage of oxytocin to increas e relatively; the NACS scale 24 h after labor was more increased significantly in observed group than controlled group. Conclusion: The un ique blockings to sense and motor were obviously separate, having no obvious eff ect to blood stream of uterus and placenta, being benificial to analgesia in per inatal. The 0.16% Rop was a more ideal local anaesthesia agent than 0.2% Rop .

AIM:To study the role of peroxisome proliferator-activated receptor-? (PPAR-?) signal transduction pathway in cardiac hypertrophy induced by high glucose and insulin (HGI). METHODS:The cultured neonatal rat cardiomyocytes were used to observe the effect of fenofibrate (FF),a selective PPAR-? agonist,on cardiomyocyte hypertrophy induced by HGI (glucose at concentration of 25.5 mmol/L and insulin at 0.1 ?mol/L). The cardiomyocyte hypertrophic responses were assayed by measuring the cell surface area,protein content,and mRNA expression of atrial natriuretic factor (ANF). The expressions of mRNA and protein were assayed by real -time PCR and Western blotting. RESULTS:In cultured cardiomyocytes,HGI induced profound change of hypertrophic morphology,the significant increase in cell surface area,protein content and ANF mRNA expression compared to those in vehicle control (P

AIM: To study the role of peroxisome proliferator-activated receptor-α (PPAR-α) signal transduction pathway in cardiac hypertrophy induced by high glucose and insulin (HGI). METHODS: The cultured neonatal rat cardiomyocytes were used to observe the effect of fenofibrate (FF), a selective PPAR-α agonist, on cardiomyocyte hypertrophy induced by HGI (glucose at concentration of 25.5 mmol/L and insulin at 0.1 μmol/L). The cardiomyocyte hypertrophic responses were assayed by measuring the cell surface area, protein content, and mRNA expression of atrial natriuretic factor (ANF). The expressions of mRNA and protein were assayed by real -time PCR and Western blotting. RESULTS: In cultured cardiomyocytes, HGI induced profound change of hypertrophic morphology, the significant increase in cell surface area, protein content and ANF mRNA expression compared to those in vehicle control (P<0.01), but the expressions of PPAR-α mRNA and protein decreased significantly (P<0.05). At the same time, the expression of cyclooxygenase 2 (COX-2), one of the PPAR-α downstream effectors was obviously elevated (P<0.05). However, FF (0.1, 0.3 and 1 μmol/L) inhibited the cardiomyocyte hypertrophy induced by HGI in a concentration-dependent manner (P<0.01). FF at concentration of 0.3 μmol/L increased the expressions of PPAR-α in both mRNA and protein levels (P<0.05) and inhibited the expressions of COX-2 (P<0.05), which were abolished by MK 886 (0.3 μmol/L), a selective PPAR-α antagonist (P<0.05). CONCLUSION: PPAR-α signal transduction pathway and its downstream effector COX-2 might involve in the cardiomyocyte hypertrophy induced by HGI.

Objective To evaluate the safety and effectiveness of immunosuppression regimens,postoperative complications,dead causes and risk factors of lung transplantation (LTx).Methods The immunosuppression regimens and clinical data of 100 patients with end-stage lung diseases receiving LTx in our hospital were retrospectively analyzed between Sept.2002 to Dec.2010.There were 72 patients subject to single LTx and 28 patients to bilateral LTx,amongst them 61 patients received LTx under circulation support,including 5 cases of cardopulmonary bypass (CPB) support and 56 cases of extracorporeal membrane oxygenation (ECMO) support.The immunosuppression regimens including Cyclosporin,mycophemolate Mofeil and corticosteroids were utilized in 53 recipients before the year of 2007,and Cyclosporin was switched to Tacrolimus in 47 patients after 2007.All the patients received Daclizumab or Basiliximab as immunosuppression induction regimens.Results The 1-,2-,3-and 5-year survival rate after LTx was 73.3％,61.6％,53.5％ and 40.7％ respectively.The mean survival time post-transplant in the patients who received Cyclosporin-based regimens and Tacrolimus-based regimens were (36.57 ± 3.44) months and (35.00 ± 2.33) months,repectively,with no significant differences (P＞0.05).The main causes of mortality included primary graft dysfunction (PGD),acute rejection (AR),bronchiolitis obliterans (BOS) and sepsis.The incidence of AR and BOS in Tacrolimus group was significantly lower than that in Cyclosporin grou (P ＜0.05),but the incidence of diabetes mellitus was significantly higher in Tacrolimus group.Analysis of Spearman rank correlation revealed that there was a direct correlation between the incidence of AR and BOS (r =0.340,P＜0.01).The use of circulation support,diagnosis of IPF,postoperative complications such as AR,BOS and infection were associated with decreased survival time postoperatively,in both univariate and multivariate proportional hazards regression models (P＜0.05).Conclusion Cyclosporin-and Tacrolimus-based regimens were both effective immunosuppression strategies postoperatively,Consummate follow-up surveillance and prompt treatment of complications were the key points in prolongation of survival time and improving quality of life after LTx.
