Objective To establish a qualitative and quantitative method for controlling the quality of Radix Puerariae and its preparation. Methods The qualitative fingerprint of effective part (extract part of ethyl acetate) was obtained by using RP-HPLC with methanol-water (42∶58) as mobile phase and UV detection at 250 nm . The quantitative measurement of effective components (puerarin and daidzein) was finished under the above chromatographic conditions. And the 11 kinds of different samples of Radix Puerariae were analyzed by the method. Results Under the qualitative conditions, the 5 common peaks in RP-HPLC fingerprint of the effective part could be used as index peaks for qualitative identification. In RP-HPLC quantitative analysis, the recoveries of the method were 98.0% with RSD of 1.30% for puerarin and 95.4% with RSD of 1.61% for daidzein, respectively. The amount of puerarin and daidzein in Radix Puerariae was 0.213%～3.626% and 0.012%～ 0.049% , respectively. Conclusion The analytical method with qualitative fingerprint of effective part and quantitative measurement of effective components of Radix Puerariae can be accurately used for controlling its quality.

Objective To study the relationship between serum fibrinogen,uric acid and the severity of coronary heart disease(CHD).Methods 156 patients with or without coronary heart disease were divided into CHD group and control group.All subjects were examined by cronary artery angiography.The severity of coronary artery stenosis was evaluated and graded with Leaman coronary scoring system.With the multiple analysis method,the relationships were studied between serum fibrinogen,uric acid and the severity of coronary heart disease.Results With multiple logistic regression,smoking,age,fibrinogen,triglyceride and low-density lipoprotein were independently associated with the severity of coronary heart disease.Gender,uric acid and other variables did not have significant independently association with the severity of coronary heart disease.With stepwise multiple regression analysis,age,fibrinogen,total cholesterol,lipoprotein(a)and low density cholesterol showed significant independent association with the severity of coronary heart disease,but uric acid and other variables did not.Conclusion Fibrinogen was related to the severity of coronary heart disease independently,but uric acid was not independently associated with the severity of coronary heart disease.

OBJECTIVE: Although the therapeutic method of stroke is progressed very quickly in recent years, the incidence of its post-depression is up to 40%. Poststroke depression many affect neural function recovery, for which, to understand it is advantageous of improving living quality of stroke patients.DATA SOURCE: The literatures relevant to poststroke depression were looked up from China medical nuclear journals and studies at home and abroad in recent 5 years on www.google.com, Medline. The Retrieval words: stroke, depression, incidence, relevant factors.STUDY SELECTION: Totally 42 relevant papers were selected on experimental and clinical studies on poststroke depression. The original literatures of non-randomized study were excluded and those of nonblind study were not excluded.DATA EXTRACTION: Of 42 papers, 10 papers were deleted because of repetition of various degrees and 32 papers were sorted out in category and 10 of those were selected as reference.DATA SYNTHESIS: The incidence of poststroke depression is about 40%, resulting from the co-factors of society, psychology and biology.It is viewed generally that the high risk phase of depression is in a couple of year after stroke and the duration of poststroke depression is various. The severity of neural functional deficits in recovery phase is affected by poststroke depression. Moderate and severe depression may delay the recovery of neural function and poststroke depression can also result in poor recovery of daily living capacity of patients, affect patients' cognition and increase the incidence of dementia. Concerning to clinical observation, a remarkable progression has been achieved on treatment of poststroke depression.CONCLUSION: The incidence of poststroke depression is very high,associated with multiple factors. Poststroke depression influences harmfully on neural function, cognition and daily living capacity. Active intervention and treatment provide a certain action on reducing the incidence of poststroke depression.
