Objective To establish a HPLC method for the determination of gallic acid in Radix et Rhizoma Rhei and to study the changes of gallic acid content in Radix et Rhizoma Rhei during processing. Methods HPLC method was used to detect gallic acid content. Diamonsil C18(250 mm?4.6 mm,5?m) column was used,and the mobile phase was a mixed liquid of MeOH -0.01 %H3PO4(10∶90). The column temperature was set up at 30℃,the flow rate was 1 mL?min-1,and the detecting wave-length was 273 nm. Results There were obvious differences of gallic acid content between the crude herbal material and different kinds of processed products of Radix et Rhizoma Rhei. The content of gallic acid was decreased in Radix et Rhizoma Rhei prepared by wine,but was increased in Radix et Rhizoma Rhei prepared by steaming with wine and by stewing with wine,and in charred Radix et Rhizoma Rhei. Conclusion The different processing methods have certain effect on the content of gallic acid in Radix et Rhizoma Rhei.

Objective To improve the method for determination of geniposide in Fructus Gardeniae.Methods The improved method was compared with the pharmacopoeia method.The content of geniposide was determined by HPLC at 238nm detection wavelength with acetonitrile-water(15:85)as mobile phase .Results The improved method in which 50 % methanol was used as solvent was superior to the pharmacopoeia method in which methanol was adopted as solvent.A higher geniposide content was abtained from the former.Conclusion The improved method is convenient and accurate,and can be used to supply reference evidence for the assay of Fructus Gardeniae in the new edition of pharmacopoeia.

Objective To explore the effect of occupational therapy (OT) on the depressive mood and activity of daily living (ADL) in patients with post stroke depression (PSD). Methods 42 patients with PSD were divided into OT group (n=21) and control group (n=21).Both 2 groups received routine therapy, and OT group received ADL training, selective recreation and sport and appreciation of music in addition.They were evaluated by modified Bathel index (MBI) and Hamilton Self-rating Scale for Depression (HAMD) before and after treatment.Results The scores of MBI increased and the scores of HAMD decreased significantly after 4 weeks in both 2 groups (P<0.001), especially in the OT group (P<0.01). Conclusion OT can improve not only ADL, but also the depressive mood in patients with PSD.

Objective To make a comprehensive evaluation of nano-composite of poly(L-lactide) and surface grafted hydroxyapatite(PLLA/PLLA-gHA) as a new material.Methods According to the evaluated critera of medical implanted materials biology and animal trial recommended in GB/T 16886 and IS0 10993 criterion,the new material was carried out on acute systemic toxicity test,haemolysis test,muscular implantation test and subcutaneous injection test.The extract liquid of new material was injected into mice by vena caudalis to test common station,toxic reaction of it at different time,the results were used to evaluate the acute systemic toxicity.Fresh anticoagulant cony blood was mixed with extract liquid of new material with density of 100 g?L-1 to measure each absorbance with spectrophotometer and work out the corresponding rate of haemolysis.The red punctuation and hydropsia of rabbits were observed at different time by subcuntaneous injecting extract liquid into the back of rabbits.PLLA/PLLA-gHA composite plates were implanted into the sacrospinal muscle of rabbits.Cony venous blood was extracted to detect indicatrix of hematology at diferrent time.The material and surrounded tissues were taken out from animals at the 14th,30th,60th,90th,180th,360th day to examine anatomic and pathological changes.Results Rabbits with PLLA/PLLA-gHA composite had good general condition.There was no any acute systemic toxicity in vivo.Data of AST and Scr had no significant difference between experimental group and control group.The hemolysis rate of extrac liquid was 1.22%,which was under the standard criteria(5%).No red punctuation and light hydropsia were observed at different time in the subcutaneous injection test.The inflammation cytochange of PLLA/PLLA-gHA composite group was similar with that of control group in early days,which was met with the general regularity of inflammatory outcome.The fibrosis membrane surrounding the PLLA/PLLA-gHA composite became thinner gradually with the elongation of implantation time.The fibrosis membrane grew into the material at the 360th day.The degree of the fibrosis membrane was below class Ⅰ.Conclusion The new absorbable type PLLA/PLLA-gHA composite has excellent biocompatibility and security.

Objective To compare the contents of berberine,palmatine,jatrorrhizine,baicalin and geniposide between traditional decoction and dispensing granule decoction of Huanglian Jiedu Decoction.Methods A HPLC method was carried out on Diamonsil C18 column(250 ? 4.6 mm,5 ?m).The mixture of H2O(A),CH3OH(B)and 0.05 % H3PO4 solution(C)was used as the mobile phase for gradient elution.The column temperature was set up at 35 ℃ and the flow rate was l mL/min.The detection wavelength was 345nm for berberine,palmtine and jatrorrhizine,280 nm for baicalin,and 238 nm for geniposide.Results This method can be used to determine 5 components in Huanglian Jiedu Decoction at the same time and the method was rapid,sensitive and accurate.Conclusion The HPLC chromatograms of traditional sliced decoction of Huanglian Jiedu Decoction are similar to the dispensing granule decoction.The contents of 5 main components in dispensing granule decoction are higher than those in traditional sliced decoction.

Objective To reach digitization of medical imaging equipment,the medical equipments were improved that have not yet equipped with digital image processing workstation system. Methods Under the premise of ensuring the stability,convenience and better cost-effective of medical image processing workstation system,the appropriate medical imaging workstation system software and hardware were selected and configured. Results Through transformation,configuration and integration,the new function of original equipment has been achieved for the desired results. Conclusion The use of the system about one year proves well economic effect and good society benefit.

0.05). In the fever experiment,the two kinds of HJD in different doses showed antipyretic effect to various degrees,but the dispensing granule decoction of HJD had the better effect,and the effect in the middle-and high-dose groups was superior to that of the low-dose groups (P

OBJECTIVE:To optimize the formula and preparation technique of oleanolic acid loaded polybutylcyanoacrylate nanocapsules(OA-PBCA-NC)by interfacial polymerization and to study its quality.METHODS:The preparation technique of OA-PBCA-NC prepared by interfacial polymerization were optimized by single factor design,and the formula was optimized by orthogonal design with entrapment ratio as index.Its shape,particle size and the entrapment ratio were investigated as well.RESULTS:The optimized dosage ratios were as follows∶ OA vs.BCA∶60mg∶0.1ml;acetic ether vs.BCA∶2.0ml∶0.1ml;and oil vs.water:1∶1.The prepared nanocapsules were round and regular in shape without adherence.The particle size was well-distributed with mean diameter at(214?8)nm and mean entrapment ratio at(76.8?0.4)%.CONCLUSION:The preparation technique of OA-PBCA-NC established in this study is stable and feasible.
