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 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.

The paper researches the co-authorship situation in the field of foreign medical ethics through the social network analysis method,taking 9 foreign core journals of medical ethics included in the Journal Citation Report as the data source,it extracts and sorts out the information through BICOMB and UCINET software to generate the co-occurrence matrix of the author and draw the map,reveals the overall structural features and co-authorship situation of the co-authorship network in the field of foreign medical ethics.

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 carry out investigation and analysis in present situation of vocational ethnics of clinical nursing teachers in order to supply reference for quality improvement of nursing staff. Methods Inter-views were carried out in 40 clinical nursing teachers in 3 teaching hospitals, Meanwhile, 700 nursing stu-dents who were in practice and probation were investigated by questionnaires about vocational ethnics of clinical nursing teachers. Results 91.5% students thought that clinical nursing teachers were uncorrupt-ed and self- disciplined, 93.0% of them considered that they could hold their ground. Most students gave positive evaluation about the teaching attitude, teaching ability and teaching practice. Conclusions We should further perfect the vocational ethnics criterion, improve cultivation system, strengthen the moral edu-cation in order to promote the vocational ethnics construction.

To observe the preventive effects of flumeprednisolone and spongia gelatinosa on peridural adhesion after nucleus pulposus resection of lumbar intervertebral disc, 153 cases with lumbar intervertebral disc protrusion were selected from the Department of Orthopaedics, Fourth Affiliated Hospital of Guangxi Medical University between June 2002 and August 2006. Among them, the flumeprednisolone and spongia gelatinosa were put surrounding nerve root and dura mater of spinal cord in 83 cases. According to the Macnab criterion, the Lasegue symptom was effectively relieved after operation, and 96.4% of excellent and good result was achieved by periodic follow-up with good functional recovery and satisfactory surgical effect. It indicates that flumeprednisolone and spongia gelatinosa composite is effective in preventing peridural adhesion after intervertebral disc operation.

TCM literature in Qing Dynasty has the characteristic of a huge quantity, a great variety, a complete taxon and an extensive spreading. Of TCM literature in other Dynasties, it has the most quantity and makes the later generation know the development of medicine in Qing Dynasty. TCM literature and development of TCM can promote each other, the development of TCM promote the publish of TCM books, on the other hand, the publish and spreading of TCM books promote the development of TCM.

HbA1c has already been one of the standard diagnostic criteria for diabetes and pre-diabetes.However,disorders of iron metabolism could affect glucose metabolism through various pathways,and influence HbA1c level directly or indirectly.So under certain circumstances,it may affect the diagnosis of glucose metabolic status.Here we reviewed researches about the interference of iron metabolism disorders on HbA1c.

Objective To explore the effect of intracoronary injection of epinephrine and Vera Pammy in patients with myocardial infarction with slow blood flowduring percutaneous coronary intervention (PCI).MethodsFrom January 2013 to October 2016, 68 patients with acute myocardial infarction with solw blood flow in Shanghai Jiading Hospital of Traditional Chinese Medicine during PCI were randomly divided into the epinephrine group(37 cases) and the verapamil group(31 cases).The two groups were treated with conventional drugs before surgery.The epinephrine group were injected into the coronary artery of 50 micrograms of epinephrine, the Vera Pammy group were injected into 200 micrograms of Vera Pammy.The coronary angiography, blood flow dynamics, as well as biochemical indexes in the two groups were observed.ResultsAfter the initial medicine, the ratio of TIMI flow grade 3 in the epinephrine group 81.80% was significantly higher than that in the Vera Pammy group 64.52%(P<0.05).The ratio of TIMI flow grade 3 after three times treatment, CTFC value after initial and 3 times treatment between the two groups have no significance.The blood pressure in the epinephrine group was (82.67±10.87) mmHg, which was significantly higher than that in the Vera Pammy group (70.46±9.54) mmHg(P<0.05).NT-proBNP, cTnT, LVEF in the two groups have no significance.hs-CRP in the epinephrine group was (7.68± 0.76) mg/L, which was significantly lower than that in the Vera Pammy group (9.25±1.05) mg/L.ConclusionThe effect is different which epinephrine and Vera Pammy were used in the patients with myocardial infarction with slow blood flowduring percutaneous coronary intervention.The use of epinephrine can significantly increase blood pressure, and the effect of initial medication is better.
