It is an urgent task to transform scientific research achievements on traditional Chinese medicine (TCM) into standard for the science and technology workers of TCM. The transformation not only improves the level of TCM standard, but also promotes the scientific research achievement on TCM into productivity. The Medium and Long-Term Strategic Development Plan for TCM Standardization issued by the State Administration of TCM of the People's Republic of China put forward reinforcement of study on method for transformation of TCM scientific research achievement into standard. Thus, this paper presented seven steps for the transformation on the basis of the TCM Standardization Regulation (trial) in order to provide some references.

The principal investigator responsibility system has been progressively under implementation at some of the domestic medical universities. However, since there are big differences between military medical universities and civilian ones in terms of organizational structures, tasks to be committed, functions and personnel systems, military medical universities have to consider own characteristics and well handle the following four pairs of relations in the process of implementing principal investigator responsibility system: the relation between the subject groups and the teaching and research sections, the relation between the subject research and the discipline construction, the relation between the subject research and the personnel training, and the relation between the collective assessment and the individual assessment in the process of performance assessment.

In this study, pEGFP-N1 was chosen as the reporter plasmid and transferred into Ctenopharyngodon idellus kidney (CIK) cells by electroporation, and the optimal electroporation conditions were determined by testing the transfection efficiency with different voltages, pulse times, plasmid amounts, and numbers of shocks. The results showed that the maximum electroporation efficiency was achieved under the following conditions in a 0.2 cm electroporation cuvette containing CIK cells (1.5 x 10(7)/mL, 200 microl): electric voltage 200 V, pulse time 45 ms, plasmid 30 microg, and one electric shock. The total genomic RNA of grass carp reovirus (GCRV) was extracted in this experiment and reversely transcribed into cDNA, which was used to amplify the gene segment of GCRV non-structural protein NS26 using designed specific primers. The PCR product was recombined into pEGFP-N1 vector. The fusion protein EGFP-NS26 was successfully and efficiently expressed in the CIK cells by electroporation, which was confirmed by both fluorescent imaging and Western blot analysis. This experiment laid a foundation for further functional studies of the non-structural protein NS26 of GCRV.

Objective: To analyze the prevalence and risk factor of co-exiting pre-hypertension and pre-diabetes condition in middle to elder adults, and to provide the theoretical basis for preventing cardiovascular disease in relevant population in Chengdu area.
Methods: A total of 5240 middle to elder adults from (40-79) years of age in Chengdu area were enrolled for a stratiifed cluster sampling study. The blood pressure, glucose and other clinical information were collected by more than 30 medical professionals with uniifed training to investigate the prevalence of co-exiting pre-hypertension and pre-diabetes condition with the risk factors.
Results: The overall prevalence rate of coexisting pre-hypertension and pre-diabetes condition was at 12.5% in Chengdu area and the standardized prevalence was at 11.5%. The prevalence rate in urban area was 12.4% and in rural was 13.2%, P=0.47, the prevalence in male gender was 12.7% and in female was 12.4%,P=0.81. With the increased age, the prevalence trend was elevated accordingly. Multi-regression analysis indicated that the elder age, overweight or obesity (female with abdominal obesity), sibling history of hypertension, hyper-triglyceridemia, multiple childbirth and menopause had the higher risk of coexisting pre-hypertension and pre-diabetes condition, allP<0.05; the higher educational level could decrease the risk of prevalence in male gender,P<0.05 and the proper exercise could decrease the risk in female gender,P<0.05.
Conclusion: There is a high prevalence rate of coexisting pre-hypertension and pre-diabetes condition in middle to elder population in Chengdu area and the prevalence is closely related to age. It is important to prevent such condition by elevating educational level nationwide, controlling waist and body weight, adjusting diet structure with proper exercise.
