OBJECTIVE:To investigate the factors influencing the drug release of atenolol nasal gel for references of optimization of its formulation.METHODS:The effects of carbopol 941(0.8%,1.0% and 1.2%)which used as the gel stroma,the amount of surface acting agent Tween-80(0,6% and 8%),and absorption enhancer(DM-?-CD vs.?-CD)on the in vitro release of atenolol nasal gel were investigated.RESULTS:All the above-mentioned 3 factors had marked effects on the in vitro release of atenolol nasal gel.The in vitro release of atenolol nasal gel was markedly enhanced by 0.8% carbopol 941,6% Tween-80 and 10% DM-?-CD absorption enhancer.CONCLUSION:The results in the study serve as references for the optimization of the formulation of atenolol nasal gel.

Objective:To construct expression vector of human glucocorticoid receptor mutant.Methods:cDNA sequence of human glucocorticoid receptor mutant having no LBD was amplificated through RT-nested PCR,PCR product was directionally cloned to pEGFP-N2 plasmid vector,and recombinant plasmids were screened through sequencing.Expressions of recombinant plasmids in human macrophage cell line U937 were observed through fluorescence microscope.Transcriptional activation activity of variant was evaluated through methods of relative activity of luciferase.Results:The 1 601 bp length cDNA was obtained,and result of sequencing confirmed the cloned cDNA sequence is completely coincidence with that of glucocorticoid receptor in Genebank.Expression products of recombinant plasmid mainly located in nucleus.Transcriptional activation activity incresed after recombinant plasmid transfected.Conclusion:Expression vector of glucocorticoid receptor mutant was constructed successfully,which has transcriptional activation activity independent of glucocorticoid.

OBJECTIVE To determine the germicidal efficacy and corrosiveness of San Xiao pyrogen inactivator.METHODS Its germicidal efficacy was measured with carrier test.RESULTS The killing rate of Bacillus subtilis var.niger spores exposed to its solution containing available chlorine 750mg/L for 30 min attained 100%.Its solution containing available chlorine 500 mg/L with a 15 min contact time could destroy HBsAg antigenicity in suspension.Its germicidal efficacy decreased in presence of organic substance.Its water solution containing available chlorine 1000mg/L was not corrosive to stainless steel,moderately corrosive to carbon steel and severely corrosive to copper and aluminum.CONCLUSIONS San Xiao pyrogen inactivator is a kind of original disinfectant which has better germicidal efficacy and uses safely.

Objective To investigate the health status of the medical staffs in our hospital , find risk factors and make corresponding strategies to improve health of status .Methods Results of physical examination on 1203 medical staffs were analyzed by SAS 9.2.Results Total residual test ratio is 9.3%, and the residual test ratio of male was significantly higher than female (χ2=38.399,p <.0001).The prevalence ratio of all subject is 60.9%, and there was no significant difference between male and female , but the higher age category, the higher prevalence ratio (χ2=211.4037,p <.0001).The top 5 diseases our staffs suffering are waist and cervical vertebra disease , thyroid nodule, hyperlipidemia, breast hyperplasia and fatty liver, in which the prevalence ratio of thyroid nodule and hyperlipidemia was different between male and female .Conclusion The health status of our medical staffs should be improved by paying high attention to medical examination and health management .

Objective To investigate the relationship between the expression of human epidermal growth factor receptor-2 (C-erbB-2), phosphorylated protein kinase B (p-Akt) and the effect of neoadjuvant chemotherapy (NAC) in breast cancer.MethodsSelected May 2014 to December 2015 in quasi in our hospital for surgical treatment of 114 cases of patients with breast cancer research, the immunity group dyeing expression levels of C-erbB-2 and p-Akt detection NAC patients before treatment in breast cancer, its relationship with the clinicopathological features of patients, NAC recent curative effect analysis.Results114 patients c-erbB-2 positive 79 cases 69.30% p-Akt positive in 77 cases (67.54%) and breast cancer c-erbB-2 positive rate, p-Akt positive rate of main and tumor differentiation degree, the occurrence of lymph node metastasis (P<0.05);negative c-erbB-2 expression in patients with NAC total effectiveness 80.00% significantly higher than the 54.43% of positive patients (P<0.05);p-Akt negative expression patients with NAC total efficiency 75.68% significantly higher than positive patients of 55.84% (P<0.05).ConclusionThe high expression of p-Akt and C-erbB-2 protein in breast cancer tissue decreased the sensitivity of NAC treatment, and the effect was not good.

Objective To explore the effect of the application of cervical loop electric knife (LEEP) in the patients with cervical micro invasive cancer.Methods Clinical data of 66 patients with minimal invasive carcinoma diagnosed by LEEP cone resection in our hospital from June 2013 to June were retrospectively analyzed. Preoperative and postoperative patients with LEEP were compared with 66 patients who underwent biopsy with biopsy, the diagnosis of micro invasive carcinoma was compared with LEEP cone resection.Results The results of colposcopy biopsy were detected in 2 cases of LSIL, 60 cases of HSIL and 1 cases of AIS, 3 cases were diagnosed as cervical microinvasive carcinoma or suspicious cervical microinvasive carcinoma, the sensitivity was 4.54%, the misdiagnosis rate was 95.46%; LEEP conization were detected in 1 cases of LSIL, 44 cases of HSIL and 1 cases of AIS, 20 cases negative margin. There was no significant difference in the thickness and area of the resected tissue between the three groups (P > 0.05). The depth of the resected tissue was significantly higher than that in the HSIL and AIS group, the HSIL and AIS groups were significantly higher than the LSIL group, the difference was statistically significant (P < 0.05). Interstitial infiltration depth is less than or equal to 1mm group, the 1 depth of stromal invasion than 3mm group and 3 < rate were 15.00%, 19.51% and 20.00% of the remaining lesion depth of stromal invasion than the patients in the 5mm group after operation, there was no statistically significant difference (P > 0.05). Cut edge positive group, positive margin group and interstitial fiber positive margin group of patients with postoperative residual disease rates were 25.00%, 15.38% and 23.80%, the difference was not statistically significant (P > 0.05).Conclusion The rate of missed diagnosis of small invasive cervical cancer is higher, and the diagnosis rate can be improved by the combination of LEEP and cone resection.

The pharmacodynamic methodology of Chinese materia medica (PMCMM) at present was discussed comprehensively in this article and the problems were found While the primary study on the PMCMM was carried out This article offers that the development of the science of Chinese traditional medicine is the premise and basis of the study of PMCMM, especially that the breakthrough of modern study on the theory of viscera state and channel theory and channel tropism theory leads dominantly the study of PMCMM; the four dimensional system theory has been investigated in PMCMM, on the two dimensional basis of the physical foundation of medicinal efficacy and the mechanism of medicinal efficacy, the time dimension and human spirit dimension are added

Objective:To simultaneous determine six flavonoids in Shuxuening injection by quantitative analysis of multi-compo-nents by single marker ( QAMS) and examine the durability and system suitability of the analysis. Methods:Shuxuening injection was the study object and rutin was used as the internal material, the relative correction factor ( f) between rutin and narcissus glycosides, quercetin-3-O-β-D-glucosyl (1-2)-α-L- rhamnoside, kaempferol-3-O-β-D-glucose group (1-2)-α-L-rhamnopyranoside, quercetin-3-O-[2-O-(1-O)-p-coumaric acid-β-D-glucose-yl]-α-L-rhamnoside, kaempferol-3-O-[2-O-(6-O)-on coumaroyl-β-D-glucose-based]-α-L-rhamnosides was respectively established. The result differences between the internal standard method and external standard method were compared, and the internal standard method was re-validated. Results: The contents of the six flavonoids in Shuxuening injection were calculated by the correction factors. Compared with those of the external standard method, the differences in the contents of the method were small( RSD<5%) . Conclusion:QAMS can be used as a simple and accurate quantitative quality evaluation meth-od for the determination of a variety of ingredients in Shuxuening injection, which provides reference for the subsequent study on quality standard.
