The intertubercular grooves of 212 humerus were studied. The statistical results showed that the depth of intertubercular grooves is highly correlated with the slope of the medial wall of the groove (r=0.116, p=0.05, lineal regression: =50.01+9.04x). It means that the deeper the groove the bigger the slope of the medial wall is, and the shallower the smaller. Their functional relationship has practical significance. The normal surface contour of the intertubercular groove is the important condition that keeps the long head tendon working normally. Therefore internal or external causes, e. g. fracture of the surgical neck, hyperplasia of the bone in aged people, may alter the normal anatomical relation of the intertubercular groove, which precipitated to tendosynovitis of the biceps. By observation of the compactness of the surgical neck cortex in three different levels, we found that it is in a transitional zone of from thin to thick, which agrees with the explanation of why fracture occurs frequently at the surgical neck.

Objective To optimize the preparation process of Xiaochuan Tiegao. Methods The effective compound imporatorin of Dahurian Angelica Root was determined by HPLC. The best condition of preparation process for the ethanol-extraction method was investigated by L9(34) orthogonal design. Results The optimum technical condition:adding 2 times ethanol, cooking 1 hour and 2 times with 90% ethanol. Conclusion The method is reliable, accurate and easy to operate.

Objective To develop an HPLC method for the assay of sinapine thiocyanate in Semen Sinapis Albae of different processed products. Methods It was assayed by RP-HPLC. The column was Hypersil BDS Phenyl (5 ?m, 250 mm?4.6 mm), the mobile phase was acetonitrile-0.08 mol/L KH2PO4 (15∶85). The UV detection wavelength was 240 nm. The flow rate was 1.0 mL/min. Results Good linearity of sinapine thiocyanate was showed within the range of 0.8～4.0 ?g (r=0.999 7). The average recovery was 100.98% (RSD=3.51%). Conclusion The method is simple, accurate and good reproducible. It can be used for quality control of Semen Sinapis Albae of different processed products.

Objective To select the optimum bases for Sihuang Gao and study the method for quality control.Method Ultra-fine powders of Radix Scutellariae,Cortex Phellodendri,Radix et Rhizoma Rhei and Rhizoma Coptidis were used to prepare Sihuang Gao with different formulations,the bacteriostatic action of which were compared and stability were inspected.The best prescription was identified by TLC,and the skin irritation was observed.Result Sihuang Gao made of water-soluble base had a strong antibacterial activity and stable quality,and it was proved no irritation,the contents of active component could be detected by TLC.Conclusion The quality was controllable,and the improvement prescription can be used in the clinic.

Objective To establish a new method for the determination of quercetin and kaempferol in wine by high performance liquid chromatography (HPLC) with chemiluminescence. Methods The procedure was based on the chemiluminescent enhancement by quercetin and kaempferol of the K3Fe(CN)6 system in an alkaline medium. The HPLC with post-column chemiluminescence was established for the determination of quercetin and kaempferol in wine. Results The standard curves were linear in the concentration ranges of 2.0?10-6-1.6?10-2 g/ml(r=0.999 0)for quercetin and 3.2?10-6-2.0?10-4 g/ml(r=0.999 8)for kaempfero respectively.The limits of detection were 1.4 ?10 -9 g/ml for quercetin and 3.4 ?10 -7 g/ml (S/N =3)for kaempfero respectively. The rates of recovery were 99.31% for quercetin and 99.06% for kaempferol. Conclusion The method is simple,rapid,accurate and applicable to the determination of quercetin and kaempferol in wine.

OBJECTIVE:To analyse the advantages and disvantages of split tablets given to in-patients.METHODS:We collected13kinds of oral tablets(10tablets each kind and260pieces of the split tablet altogether),which were often splitted by pharmaceutists.We tested and analysed the weight variation of the split tablet on the basis of the dosage consistency metioned in the USP which is applied to the whole tablet.RESULTS:None of the13kinds of prescription drug passed the consistent testing after splitting.There was some relationship between the effect of the split tablet and its shape.It was relatively easy to break off the tablet with nick in half.The loss of dosage inevitably occurred during the process of splitting the tablet.CONCLUSION:Breaking off the tablet in half led to high ratio of weight variation.The modus operandi of splitting the tablet in half for saving expenses can only be applied to those drugs with low toxicities and relatively flat dose-effect curve.In the case of those drugs which bear high toxicities and steep dose-effect curve,carefulness should always be taken when applying such method.

Objective:To purify and characterize the major antigenic components of sand swimming crab,and provide theoretical evidences for the research of standardization of allergenic vaccine.Methods:The crude extract of Linnaeus was prepared using classical method, and electrophoresis of SDS-PAGE was used to separate the proteins of each group. The allergen proteins of 26 crab were identified using Western blot. To distinguish between the primary allergen proteins and secondary allergen proteins, FPLC(Gel Chromatography and ion exchange chromatography) was used to filtrate and identify the allergen protein.Results:SDS-PAGE analysis revealed that sand swimming crab proteins were composed of at lease 9 discrete protein bands, which molecular weight ranging from 13 000 to 90 000. Major bands were of 20 900, 24 200, 27 100, 29 200, 33 700, 38 900, 48 700, 74 700, 89 100 respectively. Western blot assay indicated that the crude extract reacted with sera obtained from 26 crab allergenic subjects and contained 5 allergen bands altogether, and the bands of 74 400 and 48 700 were the major allergenic components. The positive rates of the two major allergen proteins were both 100%, indicating the allergenic components maintained the immunocompetence after yielding from chromatography.Conclusion:The 74 400 and 48 700 bands are the major allergens of sand swimming crab. The major allergen proteins can be purified by chromatography.

Objective To study the influence of the preparation and quality control of Xiaochuan cataplasm on its drug action. Methods Xiaochuan cataplasm was prepared with hydrosoluble polymers matrix. A sequence of tests such as adhesive force test, recontour test, paste-content test, cold-resistance test, heat-resistance test, toxicity and pharmacodynamic action tests were performed on this drug. Results Xiaochuan cataplasm contains a sound volume of medicine, and shows good adhesive property, no sensibilization and stimulation, and notable drug action. Conclusion The results demonstrate that the preparation craft of Xiao-chuan cataplasm is reasonable and practicable., the quality is controllable and the method is a safe and effective transdermal drug delivery system.
