The realization of symptom measurement of the traditional Chinese medicine is a must for the development of traditional Chinese medicine, which obtained a common acceptation academically. This article believed the methods for realizing symptom measurement are the combination of both TCM two basic theories of "the wholism conception" and "treatment based on syndrome differentiation" and modern scientific measures and methods. Meanwhile, the western medicine should be simply excluded, other than simply compare a TCM syndrome to a physiological and biochemical indicator of western medicine.

Academe hash't got the same view about science attribute of traditional Chinese medicine(TCM)up to now.This article demonstrates the scientific attribute of the traditional Chinese medicine from the nature of science,the seientific attribute of medical science and the relationship between the traditional Chinese medicine and medical science.TCM needs development.In order to develop the traditional Chinese medicine quickly,on the basis of inheriting tradition,we should make the best use of modem scientific technology.Not simply copy the theories and methods of western medicine but using the scientific measurement to build up the measurement of TCM symptoms,the relationship between symptoms and the change of the body,explore the process of physiology and pathology,and combine with western medicine to develop a mature science-medical science.

To construct a lentiviral shRNA vector targeting human protein phosphatase 1D magnesium-dependent (PPM1D) gene and detect its effectiveness of gene silencing in human gliomas, specific siRNA targets with short hairpin frame were designed and synthesized. DNA oligo was cloned into the pFU-GW-iRNA lentiviral expression vector, and then PCR and sequencing analyses were conducted to verify the constructs. After the verified plasmids were transfected into 293T cells, the lentivirus was produced and the titer of virus was determined. Real-time quantitative PCR and Western blot were performed to detect the PPM1D expression level in the infected glioma cells. PCR and Western blot analyses revealed the optimal interfering target, and the virus with a titer of 6×10(8) TU/mL was successfully packaged. The PPM1D expression in human glioma cells was knocked down at both mRNA and protein levels by virus infection. The expression of PPM1D mRNA and protein was decreased by 76.3% and 87.0% respectively as compared with control group. The multiple functions of human glioma cells after PPM1D RNA interference were detected by flow cytometry and cell counting kit-8 (CCK-8). Efficient down-regulation of PPM1D resulted in significantly increased cell apoptosis and reduced cell proliferation and invasion potential in U87-MG cells. We have successfully constructed the lentiviral shRNA expression vector capable of stable PPM1D gene silencing at both mRNA and protein levels in glioma cells. And our data gave evidence that the reduced cell growth observed after PPM1D silencing in glioma cells was at least partly due to increased apoptotic cell death.

Objective To investigate the efficacy of oxygen uptake efficiency slope (OUES) on evaluation the cardiopulmonary function of patients with chronic obstructive pulmonary disease (COPD). Methods The cardiopulmonary function of 54 stable COPD patients with the cardiopulmonary function of Ⅱ~Ⅳ were evaluated, following a symptom-limited Steep protocol with simultaneous respiratory gas measurement,they were performed exercise tests on a treadmill, simultaneously the oxygen uptake (VO2), carbon dioxide production (VCO2),peak oxygen uptake (VO2peak), minute ventilation (VE), and respiratory gas exchange rate (RER) were measured. OUES was derived from the relation between VO2 and VE during incremental exercise and was determined by VO2=algVE+b, where a=OUES, to measure anaerobic threshold (VAT) meanwhile. Results OUES correlated with the VO2peak (P<0.001). 75% OUES, 90% OUES and 100% OUES were not significantly different (F=0.239, P=0.830). Conclusion OUES can respond the cardiopulmonary function in patients with COPD, 75% OUES from sub-maximal exercise can be an index for cardiopulmonary function.

OBJECTIVETo evaluate the effects of Yili dark bee propolis on the main cariogenic biofilm and mechanisms.
METHODSSusceptibilities to the ethanolic extract of propolis against Streptococcus mutans (S. mutans), Streptococcus sobrinus (S. sobrinus), Streptococcus sanguis (S. sanguis), Actinomyces viscosus (A. viscosus), and Actinomyces naeslundii (A. naeslundii) were analyzed by crystal violet stain method to determine the minimum biofilm eradication concentration (MBEC). The biofilm was initially cultivated for 24 h. Subsequently, the propolis groups with different concentration MBEC and initial pH 7.0 were cultured for 24 h. Moreover, the pH value was measured to evaluate the acid-producing ability of the tested plaque biofilm. The effects of propolis on the insoluble extracellular polysaccharide synthesis of S. mutans biofilm were evaluated by anthrone method.
RESULTSThe MBEC of Yili propolis on S. mutans, S. sobrinus, S. sanguis, A. viscosus, and A. naeslundii were 6.25, 1.56, 3.13, 0.78, and 0.78 mg.mL-1, respectively. Propolis could decrease the ΔpH of the tested plaque biofilm, and the differences between the control and propolis groups were statistically significant (P<0.05). At MBEC, propolis could reduce the ability of S. mutans in synthesizing insoluble extracellular polysaccharides.
CONCLUSIONYili propolis demonstrate remarkable eradicative effects on the cariogenic plaque biofilm, showing inhibition of the synthesis of biofilm-produced acids and insoluble extracellular polysaccharides.
