Contents in orthopaedic are independent relatively and finding out the internal relations during them is helpful to improving the effect of orthopaedic teaching.Transfer theory is important tools for clinical teaching practice,and finding out the common characteristics between the orthopaedic chapters is primary for the theory.This research focuses on the following fields:fractures,nerve injury,infection,tumor and deformity.After the common characteristics between these chapters were analyzed and discussed,we concluded that the transfer theory is helpful in orthopaedic teaching practice,especially for students' comprehension and memory,but still we should avoid some negative effects in teaching process.

To explore the effective components represented by fingerprint contributed to allelopathic effect of different Salvia miltiorrhiza aqueous concentration on seeds and seedlings of radish, grey relational analysis was used to establish the chromatography-efficacy relation. The results show that 15 peaks devote high allelopathic contribution to radish seeds and seedlings. The study will provide a new concept for allelochemicals screening and study.

Objective To investigate the variations of multi-segments of the Willis' circle in cases with ACA-A1 variation.Methods Retrospective comparative analysis was applied to images of 2 246 healthy cases which were excluded from abnomalities of physical and biochemistry examination and angiostenosis caused by angiosclerosis.We divided variant group and contrast group according to variation of ACA-A1 segment.Several aspects were carried to comparison:the variation between bilateral ACA-A1 segment within the variant group was studied by x2 test; the proportion of FTP and developing of PCA-P1 were put into test.Finally we use trend x2 test to compare the variation degree of ACA-A1,ipsilateral FTP formation and PCA-P1 variation.Results Variants of ACA-A1 contains 634 cases whereas normal cases were 1 612.A prominence in variation revealed in right side of ACA-A1 (x2=26.19,P<0.01) which revealed by 429 cases in right side versus 205 cases in lefi side respectively.Parallelled with contrast group,the variant group showed immensely advantages in high proportion of FTP (x2=14.165,P<0.01) which indicated by variant group 22.56% (143/634)and contrast group 18.30% (295/1 612); but crippled in PCA-P1 formation (x2=4.32,P<0.05)which illustrated by proportions of by dysplasia and deficiency compared by variant group and contrast group was 17.35 % (110/634),14.21% (229/1 612).AC A-A 1 normal,slight variation,dysplasia and deficiency together with FTP dyformation was 9.15% (58/634),15.62% (52/333),16.50% (34/206),23.16% (22/95) respectively.Within the variation group,a pattern between ACA-A1 and FTP which fluctuated simultaneously with significant statistical discrepancies (x2=51.117,P<0.01; linear by linear x2=13.340,P<0.01)which demonstrated by ACA-A1 normal,slight variation,dysplasia,deficiency together with FTP formation was 4.57% (29/634),12.91% (43/333),16.02% (33/206),20.00% (19/95) respectively,as far as ACA-A1 variation was concerned,The variant group were more prone to develop PCA-P1 dysplasia or deficiency (x2=45.87,P<0.01; linear-by-linear x2=43.474,P<0.01).Conclusions There were more multi-variation of Willis' circle in the cases with ACA-A1 variation,MRA can value the anatomy and variation of the Willis' circle.MRA can also guide the clinic diagnosis,treatment and prognosis of the cerebrovascular diseases.

Objective To determine the contents of geniPoside in different Parts of the fruit of Gardenia jasminoides Ellis with different maturity degree Produced in fangxian,in order to find the oPtimum harVest Periods and the medicinal Parts. Methods The maturity of gardenia fruit are diVided into four leVels according to the color from totally green to yellow and red, and then the contents of geniPoside were determined by HPLC. Results The contents of geniPoside in all four leVels of maturity reached the standard by the Chinese Pharmacopoeia. The content of geniPoside in fruits of caesious color is uP to 13. 01%. Conclusion There is a negatiVe correlation between the maturity and the content of geniPoside in the mature fruit of Gardenia jasminoides Ellis. Caesious fruit has the best maturity degree. It is reasonable to use the whole fruit as medicine according to the Chinese Pharmacopoeia.
