Objective To establish an UPLC method for the determination of sinomenine in Sinomenine External Applied Powder. Methods The UPLC method was carried out on a C18 column by using acetonitrile-water-ethylene diamine (50:50:0.25) as mobile phase. The flow rate was 0.2 mL/min; the sample quantity was 2 μL; the detection wavelength was 283 nm. Results The peak time was within 1 min or so. The calibration curve of sinomenine was in the linear range of 34.2–2188.0 ng. Conclusion The method is simple, rapid, stable and reliable, which can be used for the determination of sinomenine in Sinomenine External Applied Powder.

OBJECTIVE:To optimize the preparation technology of Sinomenine topical paste. METHODS:Using“initial vis-cous force”,“holding viscous force”and“peeling strength”as index,heating and stirring time (A,h),heating temperature (B,℃) and the sequence of adding composition (softening agent,blank matrix and sinomenine)(C) as influential factors,the preparation technology of Sinomenine topical paste was optimized by orthogonal test and verified. At the same time,the content of sinomenine was determined by HPLC method. RESULTS:The optimal preparation technology of Sinomenine topical pasta was as follows as adding blank matrix and sinomenine,and then adding softening agent,heating at 80 ℃,stirring for 1 h. In verification test,RSD of comprehensive score for 3 batches of samples were 2.09%(n=3);average contents of samples were 6.7 mg/g, which was in line with the requirement of ≥6.0 mg/g. CONCLUSIONS:The optimal preparation technology of Sinomenine topical pasta is reasonable,stable and feasible. The paste shows good adhesiveness and is qualified in content.

Microcapsule technology is a high and new technology under the focused research and development in 21st century, which has been used in many research fields. However, its researches on preparation field should be paid more attention to, especially the research direction of TCM drug delivery system, which is of great value for development and application. This article reviewed the application progress of microcapsule technology in pharmaceutic preparation field, and discussed the strategic significance of the researches on TCM microcapsule preparation, with a purpose to provide research ideas and paths for the researches on the new formulations of traditional Chinese medicine.

Objective To explore the influence of accompany behavior on psychological health of neurosis patients'families.Methods 93 neurosis patients'families were divided into two groups according to whether they will accompany patients in hospital or not.The patients'families were investigated with SCL-90 when the patients were admitted and after 4 weeks admission,the psychological status were:compared between groups.Results The factor scores for sensitiveness of interpersonal relationship,hostility,phobophobia in both groups showed no difference compared with noFnl,while others were higher.when the patients were admitted At the same time,there Was no significant difference between groups.However,after 4 weeks admission,the factor scores of the subjects were no difference in experiment group compared with those when patients were admitted, whereas those in control group were lower and show significantly different.There were also difference between two groups after 4 weeks admission.Conclusions The psychological health of neurosis patients'family is abnormal,which is also aggravated by accompanying behavior,therefore we should guide the family to care for patients in right way.
