5.The Clinical Effect of Ilium Grafting Combined with Duhuojishengtang on Patients with Delayed Fracture Healing and the Changes of Hemorheology of Patients
Journal of Kunming Medical University 2016;37(6):61-64
Objective To investigate the clinical effect of ilium grafting combined with Duhuojishengtang on the delay fracture healing and explore the effect on hemorheology. Methods Eighty patients with delayed fracture healing were randomly divided into two groups. Forty patients in control group were treated by ilium grafting and 40 patients in observation group were treated by ilium grafting combined with Duhuojishengtang. The clinical effect was observed after treatment and indexes of hemorheology were recorded after different treatment time. Results The cure rate of observation group was 62.5%, which was significantly higher than that of control group 35.0%, the effective rate of observation group was 92.5%, which was significantly higher than that of control group 72.5% (P<0.01) . There were no significant differences between two groups in indexes of hemorheology after ilium grafting (P>0.05) . After the first, second, third course, the indexes of hemorheology of observation group were better than those of control group, with statistically significant differences (P<0.05) . Conclusions Ilium grafting com-bined with duhuojishengtang can improve the indexes of hemorheology, improve the cure and effective rate and also has high security. It has high clinical value and worth of popularization and application.
6.Numerical analysis of the effect of capillary geometry on oxygen transport in the microcirculation by MATLAB
Journal of Medical Biomechanics 2009;24(4):263-269
Objective Delivery of oxygen in tissues is limited in the space where oxygen must diffuse between the vascular and the surrounding tissues. Normal capillaries are relatively straight and well spaced, in contrast, the tumor vascular networks usually display more irregularity and the vessel wall shows higher permeability and less elasticity. The purpose of this study was to investigate the effect of capillary elasticity and tortuosity on the oxygen distribution and make further investigation on the mechanism of the formation of hypoxic regions in tumor. Method One-dimensional capillary model was coupled with the oxygen diffusion model. Oxygen transport was investigated in a Krogh and tortuous tissue model. The capillarygeometrywas obtained bythe one-dimensional model and transferred to the tissue model. Finite element method was employed in the analysis. Result The capillary radii along the flow direction under pressures were obtained for different initial radii and the oxygen distribution in the Krogh cylinder tissue model and the model with a tortuous capillary were computed. Conclusions when the capillary radius is small, the effect of vessel elasticity may have not significant effect on the oxygen distribution. However, with the capillary radius increasing, the effect on the oxygen transport becomes obvious. Moreover, with the tortuosity of the capillary increasing, the oxygen distribution becomes more heterogeneous, which is in agreement with the result in available reference. This work will be helpful to the investigation of oxygen transport within tumor.

8.Effect of concanavalin A on mouse islet transplantation
Chinese Journal of Pathophysiology 1986;0(01):-
To test whether Con A has antirejection effect on mouse islet allograft, 600-700 handpicked islets of C57BL/6 mice was transplanted beneath the kidney capsule of the streptozotocin induced diabetic BALB/C recipients. In control group the mean survival time (MST) of the grafts was 14.1?2.4 days. Treatment with Con A significantly prolong the MST of the islet allografts. In group with Con A treatment of the donor islets prior to the transplantation the MST was 25?5.4 days. The MST increased sigificantly after ip injection of Con A to recipient mice. The combined treatment of islet and recipient with Con A resulted in a prolongation of MST to 25.2?4.4 days. The experiments concerning the mechanisms of the antirejection effect of Con A showed that Con A was able to combine with the islet cell membrane well masking perhaps the histocmpatibility antigen. Furthermore the lymphocytes of mice after i. p Con A injection suppressed the lymphocyte proliferation reaction of the svnergic mice to mitogen.
9.Qualitative and quantitative analysis of the effective part and effective components of Radix Puerariae
Journal of Xi'an Jiaotong University(Medical Sciences) 1981;0(03):-
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.
10.SOME INTERFERENCE IN THE ASSAY OF VITAMIN E IN BIOLOGICAL MATERIALS
Acta Nutrimenta Sinica 1956;0(01):-
In this work, some interference in the assay of vitamin E in liver and serum was studied and the method was improved.The sample must be protected from oxidative attack. The interference of high vitamin A content in liver could be removed by H2SO4. The amount of KOH for saponification must be in keeping with the amount of sample assayed both in synthetic a-tocopherol and in biological material by fluorometry. A linear correlation of the fluorescence and the vitamin E content was obtained when 0.5ml of 10 N KOH was used for the saponification of 0.5-100?g of ?-tocopheryl acetate.
