Magnesium and its alloys possess the features of low density,high strength and rigidity,good biocompatibility and biodegradability.Their elastic modulus is similar to human bone,which endows them with a broad application prospect in the field of orthopedic biomedical materials.This paper reviews the current research status of magnesium and its alloys as the orthopedic implant materials and as porous scaffold materials in bone tissue engineering.Methods to improve corrosion resistance of magnesium-based metals ale briefly described as well.

Objective To study the correlation between social support for nurses and patients'satisfaction degree with nursing work.Methods The social support for nurses was evaluated by Xiao Shui-yuan's Social Support Rate Scale(SSRS).The patients'satisfaction degree with nursing work was assessed by self-designed inventory.Results The three dimensions of social support and its total score were positively correlated with patients'satisfaction degree(r=0.21～0.32).Not only the subjective support and patients satisfaction degree with nurses's care but also the objective support and patients satisfaction degree with nurses's knowledge and technique was hishly correlated.The correlation also existed in nursess'utilization degree of social support and patients' satisfaction degree with nurses's knowledge and tech-nique.Conclusion The social support for nurses was correlatd with patients'satisfaction degree with nursing work.Dood social support may contribute to alleviated patients'satisfaction degree

Based on the context of WHO International Standard Terminology on Traditional Medicine in the Western Pacific Region in October, 2007, this paper discusses the international standard of TCM terminology translation on Meridians and Collaterals and proposes some strategies on the cultural inheritance of TCM in its terminology translation.

Objective To discuss the application effect of FMEA in reduction of unplanned extubation of PICC.Methods FMEA was applied to find out the failure mode of unplanned extubation of PICC,and then assessed it from three dimensions,which were the likelihood of occurrence,the possibility of being discovered,and the seriousness of the failure,and then calculated the RPN values,risk priority,and plan optimization process,at the last made a proactive behavior intervention.81 patients were selected as the control group before the application of FMEA and 98 patients were set as the experimental group after the application of FMEA.The incidence of unplanned extubation was compared between two groups.Results There was statistically significant difference in unplanned extubation between two groups.Conclusions Application of FMEA can reduce the rate of unplanned extubation of PICC.

Pulmonary-fibrosis (PF) is the result of interstitial lung disease which has different causes and it is one of the most intractable diseases in respiratory system. The PF is characterized by progressive difficulty of breath and dying of respiratory failure, seriously threatening the health of people. Immunosuppressive drugs and glucocorticoids have been widely adopted as the main methods in treatment, but the results are not satisfactory and the side effects are obvious. Many specialists have tried traditional Chinese medicine in recent years with satisfactory effect, indicating that the prospect of using traditional Chinese medicine in the treatment of PF is optimistic. This article outlines the researches about using traditional Chinese medicine in the treatment of PF.

Objective To prepare the sinomenine hydrochloride multivesicular liposomes with high entrapment efficiency and sustained release character.Methods Multiple emulsion method was used to prepare the sinomenine hydrochloride multivesicular liposomes.Uniform design was applied to optimize the formulation and pharmaceutical process.The shape,the particle size,and the release charcter of the liposome were evaluated.Results The sinomenine hydrochloride multivesicular liposomes prepared were spherical and the size of majority particles was in the range of 20—30 ?m and well distributed.The encapsulation efficiency was more than 80% and its in-vitro release profile accorded well with the Higuchi model with t1/2 up to 52.7 h.Conclusion The formulation and pharmaceutical process of the sinomenine hydrochloride multivesicular liposomes are stable and feasible with the high encapsulation efficiency and good sustained-release character.

目的探讨运动想像和促进技术对偏瘫肩痛的康复疗效。方法31例脑卒中后偏瘫患者被随机分成运动想像和促进技术组(治疗组)18例与一般康复治疗组(对照组)13例。采用Partridge方法进行疼痛程度的评估。结果治疗后两组疼痛程度积分均明显下降(P<0.01)。治疗组明显优于对照组(P<0.01)。结论运动想像和促进技术对偏瘫肩痛的康复治疗有一定的疗效。

Objective To explore the clinical presentation,etiology of sepsis,common positions of in-fection and anti-infectious treatment of pediatric acute leukemia with septicemia resistance to carbapenem. Meth-ods A retrospective chart review of all pediatric acute leukemia with septicemia cases of Beijing Children 's Hospital from December 2011 to September 2015 were analyzed. All cases were selected based on the clinical presentation,at least one Gram-negative bacteria positive result of blood culture and were resistant to carbapen-em. The basic clinical characteristics and the results of blood culture and antimicrobial susceptibilities were ana-lyzed. Results All 45 cases with fever,among them 8 cases under went continued fever,The other 37 cases fe-ver days were ( 6. 1 ± 5. 2 ) d. Twenty-six cases had agranulocytosis. Agranulocytosis time from 2 to 79 days, mean days(15. 2 ± 16. 2)d. Significant difference of fever time between agranulocytosis team and non-agranulo-cytosis team was significant(P=0. 011). Twenty-three cases had infection positions among 45 cases. Lung,di-gestive tract,mouth and crissum were the common positions of infection. The quantum of blood culture samples were 711 parts. There were 162 parts resistant to carbapenems. The primary pathogens were pseudomonas aerugi-nosa,klebsiella pneumoniae, enterobacter cloacae and Escherichia coli. Among those 45 cases, 36 cases were cured,9 cases were ineffective treatment. Conclusion Pseudomonas aeruginosa, klebsiella pneumoniae, enter-robacter cloacae and Escherichia coli accounted for the most of G-bacteria infections resistant to carbapenem in our center. The incidence of septicemia was related to the level of granulocyte and duration of agranulocytosis.

OBJECTIVE:To set up a HPLC method for the determination of the contents of notoginsenoside R1,ginsenoside Rg1 and Rb1 in Sanqishangyao tablets.METHODS:It was performed on VP-ODS (150mm?4.6mm,5?m),and the mobile phase was acetonitrile-water with gradient elution system(0～20min(20∶80),20～26min(40∶60),26～35min(20∶80)).The flow rate was 1.0mL?min-1 and the column temperature was room temperature.The detection wavelength was 203nm.RESULTS:The liner range of notoginsenoside R1 was 0.261～7.83?g(r=0.999 9)and the average recovery was (101.12?2.03)%(RSD=2.1%).The liner range of ginsenoside Rg1 was 0.602 5～18.075?g(r=0.999 7)and the average recovery rate was (97.22?3.33)%(RSD=1.9%).The liner range of ginsenoside Rb1 was 0.537 5～16.125?g(r=0.999 6)and the average recovery rate was(100.71?2.4)%(RSD=1.6%).CONCLUSION:The method is suitable for the content determination of notoginsenoside R1,ginsenoside Rg1 and Rb1 in Sanqishangyao Tablets.
