China Journal of Traditional Chinese Medicine and Pharmacy 2005;0(05):-
The subject of modernization of Traditional Chinese Medicine(TCM) has been argued in China for many years.Many good ideas have been suggested by experts and scholars.In this paper,one issue in the modernization of TCM is discussed.The issue is how to introduce some mathematical methods into traditional Chinese medicine.This is a valuable subject to study,because by this way,the computers can be used to analyze the composing methods of TCM prescriptions and to help TCM doctors to select better treating means.A new mathematical method for analyzing the composing methods of TCM prescriptions has been developed,and the methods are still based on TCM theory.By these methods,the TCM prescriptions can be computed or analyzed in digital formations,but the integral conception about human body in TCM is still left intact.In this paper,using the new method,several TCM prescriptions were analyzed,and the analyzed results demonstrate that the methods are efficient and give a good help to understand the composing methods of TCM prescriptions.

As the progress of organ and tissue transplantation technology, pancreas and islet transplantation has been introduced to treat diabetes and became hot. However, many shortcomings and re-lated issues need to be improved concerning the islet cell sources. Bone marrow mesenchymal stem cells (BMSCs) has become the hot topic on induction of islet-like cell because it was simple to access, easy to culture and possess the function of immunosuppressian. In recent years, artificial construction of pancreatic islet cells, which uses gene recombinant and gene transfection to reforge islet-like cells, has improved the induction rate of BMSCs and increased the amount of insulin serection, and it also provide new ideas and direction for the treatment of diabetes.

With the rapid development of intensity modulated radiation therapy (IMRT) technique,the accuracy of radiotherapy has improved,while the pretreatment dose verification has become more complex.Although the experimental measurements,a widely used way to perform dose verification,is accurate and effective,its time-consuming and labor-intensive is still a challenge for physicist.The independent dose verification method such as the depth dose-off axis ratios (OAR) empirical model,Clarkson integral model,convolution model and Monte Carlo model,could partially solve these problems effectively when the accuracy is ensured within a certain range.This approach could save physicists' time to conduct dose recalculation and plan check,and has become the hotspot in the world.This paper,therefore,mainly introduces the correction-based and the model-based independent dose verification methods,and briefly discusses the development of dose verification for IMRT plans.

Objective To study the effect of Coxsackie virus B3 (CVB3) infection on islet cells in vitro, and to explore the mechanism of islet cells caused by CVB3. Methods Bone marrow mesenchymal stem cells( BMSCs) were separated from the bone marrow and cultured. Then they were induced to differentiate into islet-like cells using nicotinamide and mercaptoethanol. Differentiated cells were detected by morphology , special staining and RT-PCR. Observe CVB3 infection on islet cells under inverse microscope and detect the specific gene fragment by RT-PCR. Results BMSCs showed half suspended shape and gathered to form a cluster after induction. Cells became red brown by dithizone specific staining. RT-PCR also proved the existence of mRNA expressing insulin. Infected islet cells appeared typical pathological changes like shrinks, refraction decreases. RT-PCR detected the desired specific gene fragment of 299 bp in infected islet cells. Conclusion CVB3 can directly injury islet cells, and damage the function of islet cells of secreting insulin.

The clinical study on acupuncture-moxibustion of traditional Chinese medicine has been attracting more and more global attention. With the development of medical pattern, we hold that, to prove the therapeutic efficacy, not only modern clinical research methods should be adopted, but a scientific and standard evaluation method in accord with the features of acupuncture-moxibustion also needs to be developed. We also believe that, in the clinic of acupuncture-moxibustion, disease differentiation treatment and syndrome differentiation treatment share an equal role, as they are relatively independent but mutually unified, together boosting the completion of treatment for a type a disease in a dynamic variation process.
