An ultra-performance liquid chromatography-quadrupole/time of flight mass spectrometry (UPLC-Q-TOF-MS/MS) combined with reference herb method was developed to rapidly screen commercial sulfur-fumigated ginseng. Sufur-fumigated ginseng reference herb was prepared using genuine ginseng by conventional procedure. Then the reference sulfur-fumigated ginseng sample was analyzed by UPLC-Q-TOF-MS/MS to identify characteristic marker components. 25-hydroxyl-Re sulfate with higher abundance was se- lected as marker compound from 8 characteristic components identified in sulfur-fumigated ginseng reference herb. The fragmentation of 25-hydroxyl-Re sulfate was extensively investigated, fragment ion m/z 879.44 with higher intensity was chosen as the characteristic ion of sulfur-fumigated ginseng. The response of ion m/z 879. 44 was improved by optimizing the MS conditions so that this ion could be used as the characteristic marker ion for screening purpose in ion extracting screening mode. The established approach was successfully applied to inspect 21 commercial ginseng samples collected from different cities in China It was found that the chemical profiles of 9 samples were similar to that of sulfur-fumigated ginseng reference herb, and the characteristic ion m/z 879. 44 of 25-hydroxyl-Re sulfate was also detected in these samples, suggesting that there were nearly 43% ginseng samples analyzed being sulfur-fumigated. This findng agreed well with the results of sulfur dioxide residues of these 21 commercial ginseng samples determined with the method documented in Chinese Pharmacopeia Compared with the method documented in Chinese Pharmacopeia, the proposed approach is more rapid and specific for screening sulfur-fumigated ginseng. SFDA of China should strengthen the enforcement to prohibit ginseng being sulfur-fumigated, so that ginseng and it preparations could be effectively and safely benefit to the health of human beings.

Objective Toinvestigatetheeffectofrehabilitationrobothandontheupperlimbmotor functioninpatientswithstrokeandhemiplegia.Methods Theeffectsoftraditionalrehabilitation therapy or robot rehabilitation treatment of 15 stroke patients with hemiplegia were analyzed retrospectively. There were 4 females and 11 males. According to the group order,they were divided into either a robot rehabilitation group (n=8 )or a general rehabilitation group (n =7 ). The patients of the general rehabilitation group received general rehabilitation training at the Department of Rehabilitation Medicine for 4 weeks,3 times a week,and 30 min for each time. At the same time,they also conducted family rehabilitation training,5 times a week,once for 1 h;the patients of the robot rehabilitation group received the general rehabilitation training for the same length of time as the general rehabilitation group,and they also performed robot rehabilitation training,5 times a week,once for 1 h. The patients of both groups were evaluated with the modified Ashworth scale (MAS )scores,Fugl-Meyer motor assessment of the upper extremity(FMA-UE),andWolfmotorfunctiontest(WMFT)beforeandaftertreatment.Results Compared with before training,the MAS score of the robot rehabilitation group was decreased significantly after four weeks of training. The time in WMFT was shortened significantly and the function score was improved obviously. The scores of upper extremity,hand score,and total FMA score in FMA-UE were improved significantly,and there were significant differences (all P <0. 05 ),while there were no significant differences in various indicators in the general rehabilitation group (all P>0. 05). Comparing the effects after four weeks of rehabilitation in both groups,the robot rehabilitation group was superior to the general rehabilitationgroupforthehandscoreinFMA-UE(allP<0.05).Conclusion Therehabilitation robot hand effectively lowered the upper limb spasticity. It has significant effect for recovery motor function of hand;however,it did not have a significant effect for motor rehabilitation on wrist.

Objective:To investigate the current status and influencing factors of stroke patients.Methods:Using stratified sampling method, 458 stroke patients was investigated for the health behavior from October to December, 2015. Based on PROCEDE-PROCEED model, logistic regression analysis was conducted with the health behavior level of the subjects as the dependent variable, and the characteristic factors in the chi-square test as the independent variables to analyze the factors which influence the health behavior level of stroke patients from predisposing factors, enabling factors and reinforcing factors.Results:The health behavior score of stroke patients was (14.5±3.9), which was at medium level. The score of each dimension was nutrition (0.80±0.25), disease management (0.60±0.26), interpersonal relationship (0.57±0.33), and medication compliance (0.49±0.41). The multiple logistic regression analysis showed that the predisposition factors including age ( OR=2.03, 95% CI=1.08-3.80) and history of hypertension( OR=2.35, 95%=1.16-4.76), the enabling factors including the allocation of social resources ( OR=1.73, 95% CI=0.89-3.36), and the reinforcing factors including family support ( OR=2.03, 95% CI=0.99-4.17) were important factors which affect the health behavior of stroke patients. Conclusion:The health behavior level of stroke patients need to be improved. The relevant community resource allocation system continuously, and focus on the impact of family environment and particularly the elderly and patients with a history of hypertension should be attentioned when improving the health behavior of patients.

Objective:To evaluate the application method and effect of standardized scenario simulation teaching based on Kirkpatrick model in vocational protection education for nursing students.Methods:A historical controlled trial study was designed. Practical nursing students enrolled in 2018-2019 and 2017-2018 were selected into the experimental group ( n=203) and control group ( n=196), respectively. The experimental group adopted standardized scenario simulation teaching in the prevention and control education of needlestick injuries, and the control group adopted traditional classroom lecture. Using the Kirkpatrick model, the teaching effect of needlestick injuries protection for nursing students were compared between the 2 groups from such 4 levels as in reaction level, learning level, behavior level and results level. Results:There was no significant difference in the baseline data between the two groups in terms of age, gender, educational background and test scores of nursing professional knowledge as compared to that before practice. In reaction level: the nursing students' satisfaction of experimental group in teaching methods ( t=25.149, P<0.001) and teaching environment ( t=12.827, P<0.001) are higher than that of the control group, with statistical significance. In learning level: the test scores of needlestick injury knowledge in experimental group were significantly higher than those in control group ( t=8.221, P<0.001). In behavior level: the level of needlestick injury protection behavior in the experimental group was significantly higher than that in the control group ( t=9.250, P<0.001), and the knowledge conversion rate in the experimental group was higher than that in the control group ( t=6.054, P<0.001). In results level: the needlestick injuries incidence of experimental group was significantly lower than that of the control group ( χ2=15.815, P<0.001), the reported rate of needlestick injuries of experimental group was significantly lower than that of the control group ( χ2=14.185, P<0.001). Conclusion:The implementation of standardized scenario simulation teaching can effectively improve the effectiveness of vocational protection learning and reduce the incidence of needlestick injuries.

In order to explore reasonable artificial cultivation pattern of Thesium chinense, the biological characteristics and nutrients change in the process of winter dormancy of T. chinense was studied. The phenological period of T. chinense was observed by using fixed-point notation and the starch grains changes were determined dynamically by PAS-vanadium iron hematoxylin staixjing method. Soluble sugar and starch content were measured by anthrone-sulfuric acid method and amylase activity was determined by DN'S method. The results showed that the normal life cycle of T. chinense was two years. T. chinense was growing by seed in the first year, but growing by the root neck bud in the second year. During the process of dormancy, starch and soluble sugar could mutual transformation in different periods. T. chinense had sufficient carbohydrate to maintain growth and also a lot of small molecules to improve their ability to fight against adversity.

This article dealed with the effects of processing method and duration on the major bioactive components (sinigrin and sinapine thiocyanate) in Brassica juncea. The contents of sinigrin and sinapine thiocyanate in decoctions of raw and processed B. juncea were determined and compared by high performance liquid chromatography on a Alltima C18 column (4.6 mm x 250 mm, 5 microm) at 35 degrees C with the acetonitrile-0.1% phosphoric acid as the mobile phrase in gradient elution. The detection wavelength of sinigrin and sinapine thiocyanate was set at 227 nm and 326 nm, and the flow rate was 1.0 mL x min(-1). It was found that with the extended processing duration, the contents of sinigrin and sinapine thiocyanate first increased and then decreased: i.e., 0-2 minutes they increased gradually (for sinigrin, by 9.65% in processed products and 356. 10% in powder; for sinapine thiocyanate, by 12.82% in processed products and 3.41% in powder), and achieved their highest content at 2 min; then, decreased during the next 5 minutes (for sinigrin, by 80.35% in processed products and 82.09% in powder; for sinapine thiocyanate, by 14.29% in processed products and 17.54% in powder), suggesting that processing duration could significantly affect the contents of bioactive components in B. juncea, enzymatic hydrolysis of sinigrin when the seed is crushed in the present of moisture may be responsible for the content change. It is recommended that the slow fire should be the best processing method and the raw seed could be used directly in the water extracts related industrial production.
