OBJECTIVE:To establish the quality standard of Bikemin capsule to control the quality METHODS:TLC method was used for the identification of Ephedra sinica and the detection of limitation of aconitine in Bikemin capsule Ephedrine and pseudoephedrine in the capsule were determined by HPLC on C18 column with the detection wavelength at 215nm RESULTS:The standard curves of ephedrine and pseudoephedrine were linear in the ranges of 0 02～0 10mg/ml (r=0 9 993) and 0 01～0 05mg/ml(r=0 9 996)respectively The average recoveries were (101 4?1 78)% for ephedrine and (98 08?1 81)% for pseudoephedrine CONCLUSION:The identification method is specific and the determination method is sensitive The quality standard is suitable for control of quality of Bikemin capsule

Objectives To observe the changes of magnetic resonance imaging(MRI) during the course of treatment in hepatolen-ticular degeneration (HLD) and to evaluate its related factors.Methods Sixty - three patients with HLD received routine SE sequence MRI of brain and liver.Twenty - two patients with abnormal MRI in 42 patients and each of them had 2-4 times of serial MRI ex-aminations at interval of 1.0- 1.5 year.Results Ten patients had lesion in both brain and liver in 22 patients. Nine patients only in brain, 3 patients in liver.The major lesions disappear or decrease after rational treatments. There were only slight or no changes of MRI abnormalities in patients receiving treatments or age of patients was over 15 year old. Abnormal MRI findings shown again after stopped treatments over 2 months. In such cases, the clinical and MRI improvements were slow.The rate of clinical and MRI improvement in patients with adequate treatment were markedly higher than patients with inadequate treatment.Conclusions Liver and brain lesion will show in MRI disappear after adequate treatment;There are only slight or no change or showing again in MRI abnormalities in pa-tients with inadequate treatments compared with poor clinical improvement. MRI is beneficial to understanding therapeutic effect and prognosis of HLD.

Objective To investigate the effects of benazepril on the expression of receptors for advanced glycation end-products(RAGE)in diabetic rat kidneys,and to explore its mechanisms of renal protection in diabetic rats. Methods Thirty SD rats were randomly divided into three groups(n=10 in each group): normal control group,diabetic control group and diabetic with benazepril group.Blood glucose,blood lipid,HbA1c,kidney to body weight ratio and 24 h urinary protein excretion were detected after 12 weeks.RAGE mRNA level was analyzed by quantitative RT-PCR. Results Compared with the normal control group,the blood glucose,HbA1c,triglyceride,total cholesterol and low density lipoprotein cholesterol in the diabetic control group and diabetic with benazepril group were significantly increased(P0.05).The kidney to body weight ratio,24 h urinary protein excretion and RAGE mRNA level in the diabetic with benazepril group were significantly higher than those in the normal control group(P

Objective To investigate the status quo of transformational leadership,psychological empowerment,team psychological safety and team effectiveness,and test whether the supposed structural equation is tenable.Methods Totally 380 nurses completed the Transformational Leadership Questionnaire,Psychological Empowerment Questionnaire,Team Psychological Safety Questionnaire and Team Effectiveness Questionnaire,structural equation model was used to verify the relationship of the above,Bootstrapping confidential interval and product of coefficient were used to test the mediating effect.Results Significant correlations were found between transformational leadership,psychological empowerment,team psychological safety and team effectiveness (P ＜ 0.01),transformational leadership played indirect effect on team effectiveness (Z=6.195,P ＜ 0.05),psychological empowerment and psychological safety had a totally mediation effect.Conclusions Healthcare workers should make psychological empowerment and team psychological safety as the breakthrough point,fully play the advantages of transformational leadership on team effectiveness in order to increase the working ability of nurses and make them complete the clinical work effectively and with high quality.

The amino acid sequences of the NP,P, M, F,HN and L proteins of the paramyxovirus Tianjin strain were analyzed by using the bioinformatics methods. Phylogenetic analysis based on 6 structural proteins among the Tianjin strain and 25 paramyxoviruses showed that the Tianjin strain belonged to the genus Respirovirus, in the subfamily Paramyxovirinae, and was most closely related to Sendal virus (SeV). Phylogenetic analysis with 14 known SeVs showed that Tianjin strain represented a new evolutionary lineage. Similarities comparisons indicated that Tianjin strain P protein was poorly conserved, sharing only 78.7%-91.9% amino acid identity with the known SeVs, while the L protein was the most conserved, having 96.0%-98.0% amino acid identity with the known SeVs. Alignments of amino acid sequences of 6 structural proteins clearly showed that Tianjin strain possessed many unique amino acid substitutions in their protein sequences, 15 in NP, 29 in P, 6 in M, 13 in F, 18 in HN, and 29 in L. These results revealed that Tianjin strain was most likely a new genotype of SeV. The presence of unique amino acid substitutions suggests that Tianjin strain maybe has a significant difference in biological, pathological, immunological, or epidemiological characteristics from the known SeVs.

Objective To investigate the effects of valsartan on the expression of receptors for advanced glycation end-products(RAGE) in kidneys of diabetic rats,and to explore its renoprotection mechanisms. Methods Thirty rats were divided into normal control group,diabetes control group and diabetes with valsartan group(n=10).Blood glucose,blood lipid,HbA1c,kidney to body weight ratio and 24 h urinary protein excretion were measured after 12 weeks.RAGE mRNA level was detected by real-time quantitative PCR. Results Compared with normal control group,kidney to body weight ratio,24 h urinary protein excretion and RAGE mRNA were significantly increased in diabetes control group.Compared with diabetes control group,kidney to body weight ratio,24 h urinary protein excretion and RAGE mRNA were significantly decreased in diabetes with valsartan group. Conclusion Valsartan can inhibit renal hypertrophy and decrease urinary protein excretion in diabetic rats.The renoprotective effects may be related to its inhibition on RAGE expression.
