AIM: To set up the method for adsorbing and separating total flavone in Radix Puerariae and in Folium Crataegi. By macroreticular resin. METHODS: UV Spectrophotometry was used to analyze the content of total flavone in mixture. RESULTS: The D101 was the best for adsorbing and separating total flavone in the following technological conditions: the maximum adsorbing capacity for flavone in Radix Puerariae was 10.10mg?g -1; the maximum adsorbing capacity for flavone in Folium crataegi was 11.28mg?g -1; the current velocity was 3ml?min -1, the eluting reagent 80% ethanol (20 times the volume of medicinal herbs) and the eluting velocity 3ml?min -1. CONCLUSION: D101 resin could be used to refine the total flavone in Radix Puerariae and in the Folium Crataegi.

Objective To observe the changes in serum High Sensitive C-reactive Protein(hs-CRP)in newly dignosed type 2 diabetic patients after treament with short-term intensive insulin aspart and investigate the relationship of inflammatory factors with insulin resistant.Methods30 newly dignosed ty 2 diabetic were treated by 14 d intensive aspart treament,the levels of fasting plasma glucose(FPG),2hours postprandial glucose(2hPG),insulin and C-peptide,hs-CRP,the mean area under the curve(AUC)of insulin and C-peptide,insulin resistance index(HOMA-A),insulin secretion index(HOMA-B)were compared before and after transient intensive nsulin aspart treament.ResultsAfter the treament,FPG,2hPG,hs-CRP and HOMA-A were significantly decreased(P

Objective:By measuring the expression of nuclear factor of ?B(NF-?B) and apoptosis in the tissue of benign and malignant pancreatic diseases.Methods:The expression of NF-?B factor was measured by immunohistochemical method to measure.The expression of apoptosis for cells was determined by TUNEL method.Results: When measuring the expression of NF-?B p65 protein in the tissue,we found firstly,in the tissue of pancreatic cancer,NF-?B p65 protein was located in the nucleolus and cytoplasm,the number of positive cell was obviously more than that in the control group(P

Objective To explore the clinicopathelogical features of resectable carcinoma of the head of (pancreas).Methods A retrospcctive analysis was made on the clinicopathological data of 102 patients with cancer of the head of pancreas, who had received pancreatoduodenectomy from Nanfang Hospital in January 1990 to January 2003. Results The incidence rate of the peri-pancreatic tissue infiltration was 74.5%,the infiltration rate of retroperitonealfat was 27.5% and the incidence rate of peri-pancreatic lymph-node (metastasis) was 71.6%. Metastasis rate of 21.1% was seen in the abdominal aorta lymph nodes. (Conclusions) Surgically resectable carcinoma of the pancreatic head is not equivalent to early cancer. The surgical area of radical resection of cancer of the pancreatic head should at least include pancreatoduodenectomy and clearance of regional soft tissue and lymph nodes. It may be more reasonable if the abdominal aorta lymph nodes were assigned to the first station of lymph drainage of carcinoma of head of the pancreas.

ve To explore the hygienic safty of cosmetics for special use. Methods The detection and analysis on the hygienic safety of 432 domestic cosmetics for special use saled in Guangdong provincial markets were carried out in 2000. Results The orders of qualified rates of cosmetics for special use from high to low were as fol-lows: deodorant cosmetics (100%), hair-removing cosmetics(88.89% ), breast massage (80.00% ), antisunburn lotion (77.88%), fading cream(75.68% ). hair nourishment(64.29% ), beautifying cosmetics(50.00% ), hair dye (40.74%) and hair pem(28.57%). The highest unqualified rate of hygienic safety test on cosmetics was 17.28% for Ames test, next was 14.81% for chromosome aberration test on mammalian cells in vitro, 14.13% for eye irritation test and 10.88% for skin allergic reaction. Conclusion The management on the hygienic safety of cosmetics for special use should be strengthened further.

Objective: To determine the content of sanguinarine and chelerythrine in Macleaya microcarpa(Maxim) Fedde. Methods: RP-HPLC was adopted, kromasil C 18 column (150mm?4.6mm.5?m) with a mobile phase acetonitrile-0.1%(V/V) phosphoric acid solution(25∶75) by UV detector at 270nm. Results: The average recoveries of chelerythrine and sanguinarine were 90.2%,92.8%,RSD were 1.5%,2.4% respectively. Conclusion: A simple, rapid and sensitive method with good precision was established.

The content related to the quality during life-cycle in operation of medical device includes daily use, repair volume, preventive maintenance, quality control and adverse event monitoring. In view of this, the article aims at discussion on the quality evaluation method of medical devices during their life cycle in operation based on the Analytic Hierarchy Process (AHP). The presented method is proved to be effective by evaluating patient monitors as example. The method presented in can promote and guide the device quality control work, and it can provide valuable inputs to decisions about purchase of new device.

Bartter′s syndrome(BS) is a rare renal tubular diseases and an autosomal recessive hereditary disease. The characteristic findings are hypokalemia, metabolic alkalosis, and raised serum renin and aldosterone levels. Combination of metabolic syndrome with Bartter′s syndrome has not been reported so far. Here in, we report a case in order to call attention to the diagnosis and treatment of typical Bartter′s syndrome combined with metabolic syndrome.

Objective To approach the value of combination mode of different CT post-processing technique in diagnosing rib fine fracture.Methods 98 patients suspected with rib fractures underwent multislice spiral CT(MSCT) scanning,and CT features of rib fractures were observed with the combination of three different images:(A)volume rendering(VR),curved planar reformation(CPR) and axial view;(B)maximum intensity projection(MIP),CPR and sxial view;and(C) VR+MIP,CPR and axial view.The results were respectively recorded.Results 265 rib fine fractures were found among 98 patients.The detecting rate of fine fractures with C group was higher than that with A group (χ~2＝6.67,P＜0.01) and B group (χ~2＝6.75,P＜0.01).Conclusion MSCT four step observation method can improve the detecting rate of rib fine fracture,that is of important clinical value.

Objective To develop a model that could roundly show the phenotypes of human alzheimer disease (AD), the triple-transgenic rat model harboring APP(Swe), PS1dE9, and TAU transgenes was established in view of the advantage of rat as an important animal model on the research of nerve system .Methods APPswe/PS1dE9/TAU triple transgenic rat AD rats were generated on a SD background by co-injecting rat pronuclei with two human genes driven by the mouse prion promoter:‘Swedish’ mutant human APP (APPsw) and exon 9 mutant human presenilin-1 (PS1dE9) and human microtubule-associated protein tau gene under the control of PDGF promoter .Transgene integration was confirmed by genotyping and expression levels were evaluated by western blot ( WB ) of brain homogenates .The pathological changes were detected by human Abeta, TAU and Phospho-PHF-TAU immunohistochemistry staining (IHC).The behavioral and cognitive changes were evaluated by Morris water maze .Results One transgenic rat lines with high human APP ( Swe ) , PS1dE9, and TAU transgenic expression was selected from three transgenic founders .Compared with the wild type rat , the transgenic rat showed significant learning and memory impairments in the Morris water maze at 6 months of age .The triple transgenic rat manifested hyperphosphorylated tau and obvious aggregation of amyloid -β( Aβ) in the brain cortex and hippocampus.Conclusion APPswe/PS1dE9/TAU triple transgenic rat AD model was established .The triple transgenic AD rat fills a critical need for a next-generation animal model to enable basic and translational AD research .
