Acupuncture is a traditional empirical medicine, and evidence-based medicine(EBM) is a new medical method and development of the empirical medicine. Since 1990s, Chinese acupuncture workers began to absorb and use the methods and principles of EBM to guide acupuncture clinical research and practice. Now more and more domestic acupuncture clinicians use and follow the methods and principles of EBM. On the systemic review of acupuncture-associated articles in Cochrane library, previously effective acupuncture therapy lacks adequate evidences, which may be related to the low quality of randomized controlled trials(RCTs). In the future, only developing specialized team of acupuncture clinical research and clinical research center can radically elevate the levels of acupuncture clinical research and evaluation. Meanwhile, developing China's evidence-based acupuncture should base itself on the characteristics of acupuncture, such as emphasis on original research in ancient books,high-quality single RCTs and systemic review of non-randomized researches.

Survivin, a newly identified member of IAP family, is a powerful apoptosis-inhibiting factor. It is expressed in embryonic tissues as well as in the majority of human cancers, but not in most normal adult tissues. The cancer-specific expression of survivin makes it a potential target for cancer treatment. A survivin-specific small inhibitory RNA (siRNA) was introduced into hepatocellular carcinoma cells to investigate its effect on cancer cell apoptosis, growth and sensitivity to chemotherapeutic drugs. It was found that expressions of survivin protein and proliferation index (PI) in siRNA groups were significantly decreased, the apoptosis index (AI) of siRNA groups was significantly higher than those of others groups, and the growth inhibition rate (GIR) of chemotherapeutic drugs in siRNA groups were significantly higher than those of other groups. Our study suggests that the expression of survivin may be significantly decreased in hepG2 cell after siRNA transfection. siRNA targeting survivin could induce cell apoptosis, inhibit cell proliferation and sensitize hepatocarcinoma cells to chemotherapy. Our findings provide preliminary evidence for the therapeutic use of survivin-targeted RNA interference for human tumors that express high levels of this molecule.

BACKGROUND:Due to the differences of sport events and individual metabolic characteristics of athletes, it is difficult to establish uniform biological indexes for training monitoring. Current individual evaluation is a longitudinal analysis relying on experience or numerical variation width, which is less objective.OBJECTIVE: To explore the individual function assessment and monitoring by monitoring blood biochemical indexes and brain function indexes in elite gymnasts, in order to accurately reflect the body changes resulting from training loads. METHODS:Thirty gymnasts from the Chinese national gymnastics team preparing for London Olympic Games were enroled in this study and monitored from the last winter training until the London Olympic Games. The blood biochemical indicators and brain function indicators were measured and assessed individually according to according to the principle of quality control (alert value=mean±SD, and controled variable=mean±2SD). RESULTS AND CONCLUSION:Under the relatively uniform test conditions, it is feasible to individualy assess the blood biochemical and brain function indexes of elite gymnasts in accordance with the principle of quality control, which is more accurate and objective to reflect the body changes under training load and the current state of athletes. In addition, the combined monitoring of blood biochemical indexes and brain function indexes is more comprehensive to evaluate the body function and status of elite gymnasts.
