Conclusions Children with hyaline membrane disease should be treated with curosurf and given systemic nursing intervention as early as possible, it can rapidly improve the symptoms of hypoxia, reduce complications, decrease mortality, accelerate the recovery of disease.

Objective To investigate the effects of p38 mitogen-activated protein kinase (MAPK) short hair RNA (shRNA) delivered by lentiviral vectors (pGLV) on cardiac function after myocardial infarction (MI) in aldosterone overload rats and to explore the mechanism.Methods Aldosterone overload rat myocardial infarction model was obtained by ligating the left anterior descending coronary artery.The pGLV-shRNA was constructed,sequenced and injected into rats via tail vein.Rats were divided into 3 groups:pGLV-shRNA group (n=6),pGLV-shRNA-NC group (n=6,contained a nonsense shRNA) and the sham-operation group (n=6).Cardiac function was measured by cardiac ultrasound.Apoptosis was assessed by transferase (TdT)-mediated biotin-16-dUTP nick-end labelling (TUNEL).The p38 MAPK mRNA expression was analyzed by RT-PCR.The protein expressions of p38 MAPK and caspase-3 were detected by Western blot.Results Compared with the sham-operation group,cardiac systolic function was reduced and myocardial apoptosis index was significantly increased [(31.26 ± 4.45) ％ vs.(15.20 ± 2.18) ％,P ＜ 0.01] in pGLV-shRNA-NC group.The mRNA and protien expressions of p38MAPK and caspase 3 protein expression were significantly increased in pGLV-shRNA-NC group (all P＜0.01).Compared with pGLV-shRNA-NC group,cardiac function was improved,myocardial cell apoptosis index was reduced [(22.35±3.59)％ vs.(31.26±4.45)％,P＜0.05],and the mRNA and protien expressions of p38MAPK and caspase 3 protein expression were decreased in pGLV-shRNA group (all P＜0.05).Conclusions Cardiac dysfunction is associated with p38MAPK-mediated myocardial apoptosis in aldosterone overload MI rats.pGLV-shRNA may inhibit cardiomyocyte apoptosis and improve postMI cardiac function.

Objective To observe the efficacy of intense pulsed light(IPL)incorporated with optimal pulse technology (OPT)in the treatment of rosacea.Methods Thiris-two patients with erythematotelangiectatic rosacea and 53 patients with papulopustular rosacea were treated with IPL-OPT for 4 sessions with an interval of 3 weeks.Patients were assessed clinically and photographically by physicians before each treatment.Skin melanin index,erythema index,sebum secretion level and water content in stratum corneum were tested at the baseline,3 weeks after each treatment,and 6 months after the last treatment.Results Three weeks after the last treatment,the effective(more than 60%improvement)rate WaS 81.18%in total,75%in erythematotelangiectatic rosacea,and 84.91%in papulopustular rosacea;there WaS no significant difference between erythematotelangiectatic rosacea and papulopustular rosacea (x2=1.28,P＞0.05).Six months after the last treatment,the total effective rate still remained at 78.82%with no significant difierence from that observed at 3 weeks after the treatment(x2=1.62,P＞0.05).The value of melanin index,erythema index and sebum secretion level decreased significantly after the final treatment,however,water content in stratum corneum remained at the salne level as that before treatment.After 6-month follow-up,no significant change was noticed in the above 4 parameters compared with those obtained at 3 weeks after the treatment.Neither hyperpigmentation nor hypopigmentation was observed during the treatment and follow-up.Conclusion This study demonstrates that IPL-OPT is an effective treatment for rosacea with relatively few side effects.

Objective To investigate the changes of cardiac aldosterone and mineralocorticoid receptor (MR) in Sprague-dawley (SD) rats with chronic heart failure (CHF) induced by isoproterenol (ISO). Methods The SD rats were randomly divided into CHF group (n=9) and normal control(NC) group (n=10). The experimental CHF group was induced by subcutaneous injection of ISO, and the NC group received same dose injection of sodium chloride. The heart function was evaluated with both echocardiography and hemodynamics. The contents of aldosterone in both plasma and heart were assessed by radioimmunoassay. The expression of MR was measured by Western blot and immunohistochemistry staining. Results Compared with NC group, the heart function was decreased in CHF group, the left ventricular ejection fraction was (38.8%±4.0%) in CHF and(79. 4%±4.6%), in NC group. The maximal rate of increase of ventricular pressure (+dp/dtmax) was (7164.4±502.6) mm Hg(1 mm Hg=0.133 kPa)/s in CHF and (10199.5±462.9) mm Hg/s in NC group (both P＜0. 01 ). The contents of aldosterone both in plasma and heart were higher in CHF group than in NC group [(0.63±0.06)μg/L vs. (0.3±0.07) μg/L, (0.41±0.05) μg/kgvs. (0.08±0.01)μg/kg, both P＜0. 01]. The MR expression was increased in CHF group versus in NC group (P＜0.01). Conclusions The heart function is decreased in rats with CHF induced by ISO, which is similar to dilated cardiomyopathy. The higher levels of aldosterone both in circulation and in heart as and well as MR expression upregulation in heart may play important roles in the pathogenesis of CHF induced by ISO.
