Objective To study the therapeutic effect of Danshen injection combined with conventional therapy on children with recurrent asthmatic bronchitis. Methods A prospective study was conducted. Fifty-five children with asthmatic bronchitis admitted in People's Hospital of Henan Province from January 2012 to July 2014 were enrolled and randomly divided into a integrative Chinese and western medicine group(30 cases)and a conventional therapy group(25 cases);in the same period,18 healthy children having passed physical examinations were chosen as the healthy control group. In the conventional therapy group,rest,oxygen inspiration,anti-infection, fluid supplement and aerosol inhalation,etc. were given,while in the integrative Chinese and western medicine group,based on the similar conventional therapies,additionally Danshen injection 0.4 mL · kg-1 · d-1 was given,once per day for a total of 14 days. The wheezing remission time and the pulmonary rale extinction time were observed in the two patient groups,and the fractional exhaled nitric oxide(FeNO)content was investigated in the three groups. Results The wheezing remission time and the pulmonary rale extinction time of the integrative Chinese and western medicine group were obviously shortened compared with those in the conventional therapy group〔the wheezing remission time(days):2.3±0.8 vs. 5.2±1.1,the pulmonary rale extinction time(days):6.8±1.5 vs. 8.4±1.1,both P<0.01〕. The contents of FeNO in the integrative Chinese and western medicine group and the conventional therapy group before treatment were significantly higher than those in the healthy control group(×10-9:30.3±9.5,30.4±8.2 vs. 13.6±3.4,both P<0.01),but after treatment the FeNO levels of both patient groups were markedly lowered,and the degree of change in integrative Chinese and western medicine group was more significant(×10-9:18.6±4.7 vs. 24.0±6.8,P<0.01). Conclusion Danshen injection combined with conventional therapy can obviously down-regulate the FeNO content,alleviate the airway inflammation,effectively relieve the children recurrence of asthmatic bronchitis.

BACKGROUND: In the clinical therapy for orthopedic diseases, the traditional administration easily induces the great fluctuation of drug concentration and side effect, and implanted drug carrier material hydroxyapatite (Hap) cannot be used in human's load bearing parts due to its poor mechanical performances, and poly-L-lactic acid (PLLA) is effortlessly degraded to acid byproducts. Drug carriers made from Hap/PLLA are supposed to not only persist releasing drug onto the lesion and reduce the side effect,but also obtain strength enhancement and eliminate tissue inflammatory reaction in favor of bone regeneration.OBJECTIVE: To observe the preparation of absorbable target control-release drug carrier and simulate the application of drugs.DESIGN: Observation trial.SETTING: Chongqing Institute of Technology and Wuhan University of Technology.MATERIALS: Tails of albino rats and PLLA (offered by Biological Center of Wuhan University of Technology), pepsin (1:10 000, Sigma company), Ca(OH)2, strong phosphoric, NaOH, glacial acetic acid, phosphate buffer (pH=7.4), 1,4-dioxane, absolute alcohol (Analytical reagent available on market).METHODS: The experiment was carried out in Chongqing Institute of Technology and Wuhan University of Technology. ①Type Ⅰ collagen (Col)was prepared by acid dissolution and alkali purification methods. Hap/Col bone-like biomimetic composite was synthesized through self-assembly mechanism of materials simulating in vitro biomineralization process of nature bone. X ray diffraction analysis and transmission electron microscope were applied to observe the characterization of composite's structure and morphology. ②The resultant product of HAP/Col composite was further synthesized with PLLA to prepare the three-dimensional porous reservoir type carrier for controlled release of drug employing thermal-induced phase separation technique. Scanning electron microscope, material test machine and specific gravity test method were used to investigate the pore structure and mechanical property of carrier material. ③The prepared Hap/Col/PLLA drug carrier was loaded with bromothymol blue to investigate in vitro control-release characteristic in simulated body fluid.MAIN OUTCOME MEASURES: ①Characterization of structure and morphology of Hap/Col bone-like biomimetic composite; ②Evaluation on the property and preparation technique of Hap/Col/PLLA drug carrier; ③Assessment on results of in vitro control-release trail of model composite.RESULTS: ①Hap nanocrystals formed as slender needles aligning with its crystalline c-axis preferentially oriented.②Hap/Col/PLLA drug carrier possessed apt pore configuration and physical properties for drug controlrelease.③In vitro release test by model compound revealed an approximate zero-orderslow release prior to its 80% release percentage.CONCLUSION: Hap/Col composite material is similar with natural bone, and Hap/Col/PLLA reservoir carrier can control drug release.

Objective To discuss the effect and treatment methods of ureteral obstruction caused by primary or metastatic pelvic malignancy. Methods Clinical data of 51 cases with ureteral obstruction caused By pelvic malignancy were reviewed retrospectively.

OBJECTIVE: To investigate the expression and clinical significance of EphA2 and E cadherin proteins in papillary thyroid carcinoma tissues, and to explore the relationship between them. METHOD: Using immunohistochemical SP/PV method, we detected the expression of EphA2 and E cadherin in tumors of 43 papillary thyroid carcinomas, 11 thyroid adenoma and 10 normal thyroid tissues, then studied their relationships with clinic pathological factors. RESULT: The total positive rates of EphA2 and E cadherin expression were 58. 14% and 32. 56% in papillary thyroid carcinoma tissues, 18. 18% and 81. 81% in thyroid adenoma.tissues and they were 10. 00% and 100. 00% in normal thyroid tissues respectively. The positive expression of EphA2 in carcinoma tissues was higher than in the thyroid adenoma tissues and normal thyroid tissues (P<0. 05) and the positive expression of E cadherin in carcinoma tissues was lower than that in the thyroid adenoma tissues and normal thyroid tissues (P<0. 05). The positive expression of EphA2 and E cadherin was associated with lymph node metastasis and histological grade (P<0. 05), but it was not associated with all the clinic-pathological factors including age, sex and the tumor size (P>0. 05). In papillary thyroid carcinoma tissues, the expression of EphA2 was negatively correlated with the expression of E cadherin protein (r= -0. 416, P<0. 01). CONCLUSION EphA2 and E cadherin may be involved in carcinogenesis and development of papillary thyroid carcinoma.
