OBJECTIVE:To observe the efficacy and safety of aerosol inhalation recombinant human interferon α1b in the treat-ment of bronchiolitis in children. METHODS:60 children with bronchiolitis were randomly divided into low-dose group,high-dose group and control group. All children were given tracheal suctioning,phlegm dispersing and other symptomatic treatment. Based on it,low-dose group was given recombinant human interferon α1b 1-2 μg/(kg·times),adding into 3 ml 0.9% Sodium chloride injec-tion,compression aerosol inhalation,twice a day;high-dose group was given recombinant human interferon α1b 3-4 μg/(kg·times), adding into 3 ml 0.9% Sodium chloride injection,compression aerosol inhalation,twice a day;control group was given ribavirin 10-15 mg/(kg·d),adding into 5% Glucose injection at ratio of 1∶1 by intravenous infusion,once a day. The treatment course for all groups was 5-7 d. Clinical efficacy,disappearance time of cough,respite,rale and three depressions,hospitalization time and incidence of adverse reactions in all groups were observed. RESULTS:Disappearance time of cough,respite,rale and three depres-sions and hospitalization time in high-dose group were significantly shorter than low-dose group and low-dose group shorter than control group,the differences were statistically significant(P<0.05). Total effective rate in high-dose group was significantly high-er than low-dose group and low-dose group higher than control group,the differences were statistically significant (P<0.05). There were no obvious adverse reactions during treatment. CONCLUSIONS:Based on conventional treatment,both efficacy and safety of aerosol inhalation recombinant human interferonα1b in the treatment of bronchiolitis in children are good.

Objective To evaluate myocardial apoptosis with 99Tcm-C2A-GST myocardial imaging using the recombined C2A domain of Synaptotagmin Ⅰ by gene engineering. Methods ( 1 ) The C2A gene was inserted into the prokaryotic glutathione S-transferate (GST) fusion protein expression plasmid pGEX-6P-1. The recombinant plasmid was transformed into E. coli BL21. C2A-GST fusion protein was purified after BL21 was induced with isopropyl-β-D-1-thiogalactopyranoside (IPTG). (2)The activity of fusion protein was identified by cell binding test with fluorescein-5-isothiocyanate (FITC)-C2A-GST. (3) The C2A-GST fusion protein was labeled with 99Tcm using 2-iminothiophene hydrocoride method. Radiochemical purity was determined with thin layer chromatography. (4)99Tcm-C2A-GST (7.4 MBq) was injected to ischemia-reperfusion rat models through tail vein. The image was acquired with SPECT at 1 h after injection, and then hearts were removed, rinsed with saline and dyed with triphenyl tetrazolium coride (TTC). The ischemic myocardium was separated from the viable myocardium and was weighted. Its radioactivity was measured by gamma counting. The difference of uptake of radiotracer between ischemic myocardium and normal myocardium was compared using percentage activity of injected dose per gram of tissue ( % ID/g) with standard deviation. SPSS 12.0 and t-test were used for data analysis. Results ( 1 ) C2A-GST fusion protein wassuccessfully expressed and its relative molecular weight was 3.8 × 104. (2) FITC-C2A-GST binding to apoptotic cells could be observed by fluorescent microscopy. (3) The radiochemical purity of 99Tcm-C2A-GST was (98.90 ±0.43)%. (4)The imaging studies showed that there was focal uptake of radioactivity in the ischemic myocardium. In vitro uptake of 99Tcm-C2A-GST was (2.41 ±0.32) % ID/g by the ischemic myocardium, however 99Tcm-C2A-GST-N-hydroxysuccinimide (C2A-GST-NHS) was (0. 82 ± 0. 24) % ID/g. There was statistically significant difference between those two groups (t = 10. 6, P ＜0.01 ). Conclusion The C2A domain of Synaptotagmin Ⅰ expressed by gene engineering can be used as the tracer for noninvasive detection of ischemic myocardium in the ischemia-reperfusion rat model.

Objective To study the clinical therapeutic effectiveness and the mechanism of Shouti Oral Liquid on simple obesity children with hyperinsulinism. Methods Fourty - three patients were divided randomly into the treatment group (TG) and the control group (CG). TG took Shouti Oral Liquid and CG took metformin. The course of therapy lasted 6 months. The plasma lipid, body fats, insulin resistance index (IR) and some hormones related to obesity before and after therapy were measured and the changes were analyzed. Results The weight, F% , body mass index (BMI), leptin(LP), tumor necrosing factor (TNF - ?), FINS, IR all declined markedly than pre - therapy in both groups. The significant effect, normal effect and total efficiency were 22.7 % , 59.1 %, 81.8 % respectively in TG and9.5%,52.4%,61.9% in CG. The effect in TG was better than that in CG. A short course with Shouti Oral Liquid therapy did not have obvious side effect Conclusions There are lipid metabolism disorder, insulin resistance and high lever LP and TNF - ? obesity children with hyperinsulinism. The total effect with Shouti Oral Liquid is better than that with medicine in the control group and the mechanism was regulating lipid metabolism, decreasing LP and TNF-? and ameliorating insulin resistance.

Objective To investigate the association of MRI features with HER-2 expression in non-mass-like breast carcinoma. Methods 74 patients with breast cancers diagnosed by pathology underwent MRI prior to surgery,and all lesions were non-mass-like enhancement on dynamic contrast-enhanced MRI.The expression of HER-2 in tumor tissue was detected by immunohistochemical staining.Chi-square test,Fisher’s exact test and spearman rank correlation were used to evaluate the correlations between the morphological characteristics, dynamic enhanced MR parameters,ADC value and HER-2 expression.Results The tumor size was correlated positively with the expression degree of HER-2 (r=0.341,P =0.003).The ADC value was also correlated positively with the positive expression degree of HER-2 (r=0.31 7,P =0.006).However,the time to peak was correlated negatively with that (r =-0.244,P =0.036).No significant correlations between the distribution/internal enhancement manner,the type of time signal intensity curve and HER-2 expression were found (all P >0.05).Conclusion Tumor size,time to peak and ADC value are correlated with the expression of HER-2 in non-mass-like breast carcinoma,which is helpful for the treatment plan and prognosis evaluation for this cancer.

Objective To assess the effect of anemia on long-term outcomes in patients with acute coronary syndrome(ACS) undergoing pereutaneous coronary intervention(PCI). Methods In 3136 patients presenting with ACS,636 patients were anemic. The clinical features, mortality and major cardiocerebral events including non-fatal acute myocardial infaret,revascularization and non-fatal cerebral stroke were compared in patients with or without anemia. The average follow-up period was 550 days. Results Anemic patients were older and had a higher percentage of comorbidities compared with nonanemic cohorts. Compared with nonanemic patients, anemic patients had higher mortality (4.7% versus 1.5% ,P <0. 001) and a higher major adverse end point events,including nonfatalmyocardial infarction, stroke and revaseularization (14.2% versus 11.0%, P = 0.032). After adjustment for comorbidities, anemia was associated with a higher risk of mortality after percutaneous coronary intervention (adjusted hazard rate ratioRR2. 166 ;95% CI 1. 298-3. 612 ;P =0.003). Conclusion Anemia before PCI is an independent factor for predicting the long-term mortality of ACS.
