Journal of Medical Postgraduates 2003;0(05):-
Alteration in gastric emptying may play a role in the pathogenesis of many diseases.And various methods to measure gastric emptying have been developed.Nine procedures for the assessment of gastric emptying were reviewed in this paper including intubation test,radiology method,absorption test,real time ultrasound,breath test,radionuclide technique et al .Among all of these methods,radionuclide technique is considered as the good standard method.
2.Separation and Analysis of Bacteria by Capillary Electrophoresis
Microbiology 1992;0(03):-
Recent developments on separation and analysis of bacterial cells by capillary electrophoresis are reviewed. Based on bacterial surface characterization, capillary electrophoresis technique can be utilized for rapidly identify and quantify intact bacteria and microbes at a certain phase. The microbe-molecule interactions can also be described. The separation of microbes that can not be cultured in lab appears to be possible by this method. It makes profound effects on separation science and microbiology to establish capillary electrophoresis procedure for the separation and analysis of bacterial cells.
3.THE MACRO-MICRO-ANATOMY OF THE VESSELS OF THE SKIN FLAP IN THE FRONTO-PARIETO-TEMPORAL REGION
Acta Anatomica Sinica 1954;0(02):-
The vessels of the skin flap in the fronto-parieto-temporal region were studied by way of injecting 10% ethyl acetate dye into the artery of 25 Chinese adult cadavers.The main arterial supply in this region is the superficial temporal artery. In addition,the posterior auricular,supraorbital and supratrochtear arteries distribute over this region as well.The superficial temporal artery is the largest scalp artery.The area distributed by this artery amounts to 57.38?6.05% of the whole scalp.The frontal and parietal branches are the terminal branches of the superficial temporal artery.The former is a constant branch in our cases.It is a dominant vessel of which both the distributing area and the caliber are larger than the parietal branch.The superficial temporal vein is mainly formed by the union of a frontal and a parietal venous branches,which approximately accompany the corresponding branches of the artery. The arteries in the fronto-parieto-temporal region form rich anastomoses at the median area of the vertex.The large anastomoses channels were counted in this study.These channels have anatomically provided for the designing of a supe(?)long flap which run across the median zone.The forehead flap with the frontal branch as the pedicle artery and the scalp flap with the parietal branch as the pedicle artery were discussed.

Chinese Journal of Medical Education Research 2012;(12):1289-1291
At present,there are many problems in the cultivation for medical students including lack of humanistic education,insufficient healthy personality shaping and innovation education.We made explorations in aspects of updating education concept,enhancing faculty construction,emphasizing basic course teaching and promoting students' abilities so as to cultivate the comprehensive quality of students majored in medical imaging (ultrasonic medicine).
6.Ligustrazine inhibited TNF-α-induced TGF-β1 and CTGF expression in human peritoneal mesothelial cells
Basic & Clinical Medicine 2009;29(11):1185-1188
Objective To investigate the effects of Ligustrazine on TNF-α-induced TGF-β and CTGF expression in human peritoneal mesothelial cells (HPMCs). Methods HPMCs were isolated from human omenta by trypsin di-gestion. Then, the subcultured HPMCs were divided into control group, TNF-α-induced (1 μg/L) group and TNF-α-induced plus low-, medium-and high-dose Ligustrazine (10, 20 and 40 mg/L Ligustrazine respectively) groups. The viability of HPMCs was measured by MTT assay. RT-PCR was used to detect the expressions of TGF-β1 and CTGF mRNAs in HPMCs. TGF-β1 and CTGF in supernatants were measured by ELISA. Cell protein concentration was measured by trace bicinchoninic acid (BCA) method to validate the ELISA assay results. Results Ligustrazine significantly decreases TNF-α-induced TGF-β1 and CTGF expression in a dose-dependent manner at both protein and gene levels ( P < 0. 05 ). In addition, medium-and high-dose Ligustrazine injection significantly ameliorates the viability of HPMCs inhibited by TNF-α ( P < 0. 05 ). Conclusion Ligustrazine inhibits expressions of TGF-β and CTGF of HPMCs in an inflammatory conditions.

9.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.
