Objective: To establish the determination of imperatorin and isoimperatorin in Tongketing Capsule (Radix Angelicae Dahuricae, Pheretima, etc.) by HPLC. Methods: The determination was carried out by HPLC. The mobile phase was acetonitrile water (60∶40) and UV detection wavelength was set at 245nm . The flow rate was 1.0mL?min -1 . The column temperature was 40℃ . Results: There were the good linear relationship between the absorption area value and the concentration in the range of 65?g～325?g for imperatorin and in the range of 50?g～250?g for isoimperatorin, respectively. The average recoveries were 98.3% ( RSD = 1.73% ) and 98.7% ( RSD = 1.65% ), respectively. Conclusion: The method is simple, accurate and can be used to determine imperatorin and isoimperatorin in Tongketing Capsule.

OBJECTIVE:To investigate the status quo and problems of the construction of pharmacy staff team from Hubei Wuling mountainous area,and to provide reference for the formulation of construction plan of pharmacy staff team. METHODS:Using questionnaire survey and telephone interviews,the pharmacy staff of 22 hospitals at second level or above from Hubei Wul-ing mountainous area during 2011-2014 were investigated in terms of number,age,educational background,professional title,etc. RESULTS & CONCLUSIONS:The shortage of pharmacy staff is seious in 22 hospitals at second level or above from this areas (open 10 606 beds,should be staffed 956 pharmacy personnel,actual number of pharmacy personnel is 502);the age structure is unreasonable,and only 220 pharmacy staff aged under 35 year-old;highly educated pharmacy staff accounted for low proportion, and bachelor degree or above took up 29.5%;pharmacy staff with professional title took up low proportion,and pharmacy staff with high,middle and junior professional titles accounted for 1:5:4. The situation of pharmacy staff in the region can be improved through following measures,including striving for policy recommendations,continuously enriching the quantity of pharmacy staff, integrating scientifically and building reasonable talent tem gradually,introducing talents,optimizing education structure of pharma-cy staff,strengthening the training,improving operation level of pharmacy staff,etc.

Objective To explore correlation between gene polymorphism of TNF-alpha and thyroid associated ophtalmopa thy (TAO) in Zhuang ethnic population.Methods DNA and serum samples were collected in patients with TAO in Han/Zhuang population.ELISA was applied to detect level of TNF-alpha in serum and PCR was applied to detect polymorphism of TNF-alpha gene 863C_A.Results The levels of TNF-alpha in patients with TAO increased significantly compared with control group (P ＜ 0.05),and more significantly in Zhuang population compared with Han population (P ＜ 0.05) ;gene frequency of CA was significantly higher in patients with TAO in Zhuang population than that in Han population (P ＜ 0.05),while gene frequency of AA was significantly lower (x2 =0.770,2.145,all P ＜ 0.05).Conclusion Serum level of TNF-alpha increases during occurrence of TAO,and the differences of expression level between different nationalities are due to gene polymorphism of TNF-alpha.

Enterovirus 71 (EV71) is one of the primary causative agents of hand, foot and mouth disease in children and closely associated with severe neurological complications and even deaths.EV71 outbreaks have occurred throughout the Asia-Pacific region since 1990s, posing global public health threat;however, no specific therapeutic strategy exists for severe EV71 infection.Several inactivated vaccine products have entered or finished the clinical trial stage, and some novel vaccine candidates, including live attenuated, subunit, and virus-like particle, show great potential for further develop-ment.This review summarizes the present situation and progress in the development of EV71 vaccines.

BACKGROUND:With the development of the research, induced pluripotent stem cel s are applied to the build of disease model, drug screening, regenerative medicine, and many other research fields, and have made significant achievements, especial y in the study of nervous system diseases.
OBJECTIVE:To summarize the recent development of induced pluripotent stem cel s and to raise problems and prospects based on the latest research in this field.
METHODS:The first author searched the PubMed database for articles about the induced pluripotent stem cel s, including reviews, clinical research and basic research, published from January 2006 to September 2014. The keywords were“iPS, induced pluripotent stem cel”, and final y 60 articles were included in result analysis.
RESULTS AND CONCLUSION:Induced pluripotent stem cel research continues to make breakthrough from its discovery by Yamanaka’s team in 2006 to winning Nobel Prize in 2012. Induced pluripotent stem cel research has broad prospects in the disease model construction, drug screening and regenerative medicine. Currently, problems such as reprogramming methods, cel stability, and clinical transformation stil need to be solved, and further researches are necessary.

A new method of acquiring electromyographic is presented.An EMG signal acquisition system is developed based on virtual instrument,which adopts traditional electromyographic instrument,high performance data acquisition card and Labview software.The real-time acquisition,digitalization and display of electromyographic signal are realized through the new system.Adapted to various physiological signals with the expanded functions,the system can be considered as the future physiological instrument's direction.

Objective To study the optimum inclusion process for volatile oil from Tongketing capsules. Methods The study was carried out with orthogonal test at different levels. The utilization ratio of volatile oil was used as the index to optimize the inclusion process. Results The optimum preparation conditions for inclusion were: oil: ?-cyclodextrin: water was 1: 4: 40 (V: V: V). The inclusion time was 10rain and inclusion complexes was dried at 70℃. Conclusion This optimized process is simple, efficient and can be used for the production of Tongketing Capsule on a large scale.

Objective To evaluate the effect of scene simulation on improving nurses′communication ability in the emergency department. Method Twenty nurses from the emergency department were trained with the scenario simulation. A comparison was done between the pre- and post-training abilities in terms of their ability in communication and the satisfaction degree of patients. Results The total score scores in every dementions on nurses′communication ability after training was significantly higher than those before training(all P<0.05). The score on satisfaction degree with nurses after training was significantly increased compared with that of pre-training and satisfaction degree of patients (all P < 0.05). Conclusion Scenario simulation training is helpful for the improvement of nurses′communication ability.
