When cultured heart cells were exposed to X-XOD containing medium, the absolute values of APA, OS, Vmax, APD, MDP, TP decreased; the percentage of beating clusters reduced in single MEM medium, but the frequency increased sharply in Ba containing medium. The longer the period exposed to X-XOD, the more significant are the variations of the electrical and contractile indices. The effects of X-Mo was similar to that of X-XOD, but to a slightly less extent. Se significantly converted all the indices. It is concluded that X-XOD can induce serious injury of cultured myocytes, and so does the X-Mo, while Se can protect the cells from the injury.

Objective To explore the relationship between bronchial pneumonia in children and the level of myocardial enzyme , C-reactive protein (CRP) and platelet count .Methods 1 000 cases of children with bronchial pneumonia from August 2010 to De-cember 2010 were retrospectively analyzed (bronchial pneumonia group) ,According to the clinical symptom severity ,the children wwer divided into mild bronchial pneumonia group and severe bronchial pneumonia .1 000 healthy children were recruited in control group(control group) ,and the changes of myocardial enzyme ,platelet count and CRP were tested .Results The myocardial enzyme , including aminotransferase (AST ) ,lactate dehydrogenase (LDH ) ,a- hydroxybutyric acid dehydrogenase (alpha HBDH ) ,serum creatine kinase (CK) ,CK isoenzyme (CK-MB) ,platelet count and CRP in bronchial pneumonia group were all higher than that of control group (P<0 .05);In the severe bronchial pneumonia group ,the increased rate of AST ,LDH ,α-HBDH ,CK ,CK-MB ,plate-let count and CRP indicators were significant higher than that in the mild pneumonia group (P<0 .05) .Conclusion The determina-tion of myocardial enzyme ,platelet count and CRP would be useful and helpful for the diagnosis of children bronchial pneumonia ,in particular the severe bronchial pneumonia .

Principles of constructing medical information technology curriculum system were pro-posed revolving round the core problem of how to combine needs of developing life science with culturing talents who can independently apply information technology knowledge in studying and researching. De-tailed implementing measures for constructing medical information technology curriculum system were summarized after repeated practical teaching. Longitudinal classification based on discipline and trans-verse classification based on teaching level were combined to construct the whole standard course. Finally, courses were appropriately distributed according to detailed culturing objectives for students in medical universities and colleges,thus a suitable medical information technology curriculum system in medical universities and colleges was formed.

After the need of medical information professionals was analyzed, the reform of training model for medi-cal information professionals in Department of Information Management and Information System, Hubei Medical and Pharmaceutical College, was described in aspects of the position of its training target, construction of its teaching team, optimization of its course teaching system structure, updating of its teaching methods, and improvement of its practical ability training system in order to provide certain beneficial experiences and reference for the training of medical information professionals in higher education institutions.

0 35 The patients had no endocrine or immune disease and received neither radio , chemo nor hormone therapy Anesthesia was induced with propofol, midazolam, fentanyl and succinylcholine After tracheal intubation the patients were mechanically ventilated Anesthesia was maintained with enflurane inhalation and intermittent intravenous boluses of midazolam, fentanyl and vecuronium After operation the patients were transferred to recovery room and PCA was started when the patients were wide awake VAS was maintained at 2 4 Venous blood samples were taken before surgery, before blood transfusion and on the 1st and 5th postoperative day for determination of T lymphocyte subsets and natural kill cell counts by flow cytometry (EPICS Elite USA) Results The two groups were comparable regard to sex, types of operation, intraoperative blood loss and volume of fluid infused The mean duration of operation of the two groups was (196?42) min The NK cell and CD + 3 and CD + 4 counts and CD + 4/CD + 8 ratio before transfusion were not significantly different from those before operation in both groups The NK cell, CD + 3 and CD + 4 counts and CD + 4/CD + 8 ratio decreased significantly on the 1st postoperative day in both groups but the decrease was more pronounced in group H On the 5th postoperative day the NK cell, CD + 3, CD + 4 counts and CD + 4/CD + 8 ratio returned to preoperative level in group A but remained low in group H Couclusions Perioperative homologous blood transfusion has serious and prolonged inhibitory effects on patient′s immune function In autologous blood transfusion group the changes are milder and the recovery is more rapid as compared with those in group H

Objective To investigate the therapeutic effect of ambroxol hydrochloride on severe pneumonia, and the influence on the inflammatory cytokines of TNF-alpha and hs-CRP etc.MethodsThe clinical data of 70 patients with severe pneumonia patients treated in our hospital from December 2014 to August 2016 were retrospectively analyzed.The patients were divided into control group(n=30) and observation group(n=40) according to the treatment methods, the control group was given routine treatment, the observation group was given ambroxol hydrochloride on the basis of conventional treatment.The therapeutic effect of the two groups was observed, the differences of serum levels of inflammatory cytokines, pulmonary function, cough and expectoration symptom scores of the two groups were compared before and after treatment.ResultsThe effective rate of the observation group was 97.50%, which was significantly higher than that of the control group(80.00%);There was no significant difference in serum inflammatory cytokine levels between the two groups before treatment, after treatment,the levels of IL-6, IL-8, hs-CRP and TNF-alpha the observation group were lower than those in the control group;There was no significant difference in the indexes of lung function between the two groups before treatment.After treatment, the levels of FVC, FEV1 and FEV1/FVC in the observation group were higher than those in the control group;There was no significant difference in symptom score between the two groups before treatment.After treatment, cough, sputum volume, cough ease and wheezing scores in the observation group were lower than in the control group.ConclusionAmbroxol hydrochloride has a good therapeutic effect on severe pneumonia,which can significantly reduce the levels of inflammatory cytokines such as TNF-α and hs-CRP, and improve the related symptoms, and has good application value.

Objective To observe the effect of tiotropium combined Seretide in the treatment of elderly patients with moderate to severe COPD clinical curative effect and the influence on the quality of life of patients.Methods114 cases of moderate or severe COPD in our hospital from January 2014 to January 2016,were randomly divided into observation group and control group, 57 cases in each group.The control group was treated with Seretide treatment, the observation group were treated by tiotropium combined with Seretide treatment, compared two groups of patients with curative effect and quality of life.ResultsBefore treatment, there were no significant differences in lung function index, MRC score, 6MWT and WHOQOL-100 scores between the two groups;After treatment, FEV1/FVC and FEV1% in the observation group were significantly higher than in the control group, and the difference was statistically significant (P<0.05);the dyspnea severity score (MRC) and six minute walk test (6MWT) in the observation group were significantly better than those in the control group, and the differences were statistically significant (P<0.05);the quality of life score (WHOQOL-100) in the observation group was significantly higher than in the control group, the difference was statistically significant (P<0.05).ConclusionTiotropium bromide combined with nimesulide in the treatment of elderly patients with moderate or severe COPD is effective, and can effectively improve the level of pulmonary function, improve the quality of life of patients.
