China Journal of Traditional Chinese Medicine and Pharmacy 2005;0(08):-
Objective: To analyze the published domestic documents of the clinical trial for treatment of anal fissure in past 10 years, to evaluate the quality of literatures about anal fissure randomized controlled clinical trials, and to provide references of clinical studies for the treatments of anal fissure in Traditional Chinese Medicine (TCM). Methods: In term of principles of evidence-based medicine, we evaluate the published domestic literatures of the randomized controlled clinical trial for treatments of anal f issure in past 10 years. Results: We analyze 52 literatures which are in the method of randomized controlled clinical studies. 28 literatures (accounting for 53.85%) record diagnostic criteria, 38 literatures (accounting for 73.08%) make sure standards of evaluating the effect and 18 literatures (accounting for 34.62%) mention comparability between groups without describing the baseline statistics. Only 5 are marked as a funded research projects. Conclusion: in current published literatures of randomized controlled study for treatments of anal fi ssure, the problems are focused on: ① Experimental idea is unclear and design is unreasonable, ② The description of implemented process in randomized control is unspecif ic, ③ Signifi cant parameters in statistical data are missed and with less credibility, ④ Criteria of diagnosis and effi cacy are different, ⑤ Evaluation indicators are fuzzy. All above clue to the quality of clinical research needs to be improved rapidly, and standardized evaluation of eff icacy also needs to be created urgently.

The sub-health status is closely related to the functions and activities of heart in traditional Chinese medicine (TCM). The sub-health is commonly presented with a series of heart system symptoms such as palpitation, chest distress, shortness of breath, fatigue, fidgets and insomnia. It may also be accompanied with arrhythmia or blood pressure value between normal and high level. This heart system sub-health status can be transformed into re-lated heart system diseases with high possibility. This article made a review from aspects of theoretical literature, an-imal experiment, curative effect observation and clinical evaluation on the research progress of heart system sub-health status.

In this paper, the Fourier transform based minimum mean square error (FT-based MMSE) method is used to calculate the regional cerebral blood volume (rCBV) in magnetic resonance (MR) perfusion imaging, and the method is improved to handle the existing noise in the imaging process. In the experiments with signal-to-noise ratio (SNR) of 50 dB, the rCBV values were compared with the results using MMSE method. The effects of different SNRs on the estimation of rCBV were analyzed. The experimental results showed that MMSE was a simple way to filter the measurement noise, and could calculate rCBV accurately. Compared with other existing methods, the present method is not sensitive to environment, and furthermore, it is suitable to deal with the perfusion images acquired from the environment with larger SNR.

] Objective To explore the role and mechanisms of FGF2 in chemo?resistance in breast cancer. Methods The inhibitors for different signal pathway were used to treat two drug?resistant breast cancer cell lines MCF?7/5?Fu and T47D/5?Fu established in our lab. MTS assay was used to determine chemo?sensitivity and Hoechst stain was used to measure apoptosis. Protein activation and FGF2 protein level in cell culture medium were detected by western blot and ELISA respectively. Results Akt inhibitor MK?2206 (20 nM) and mTOR inhibitor AZD8055 (2 nM) significantly reversed the chemo?resistance of MCF?7/5?Fu and T47D/5?Fu cell lines to 5?Fu and paclitaxel, but ERK1/2 inhibitor SCH772984 showed no significant effect. Compared to parent cell lines MCF?7 and T47D, p?Akt and p?S6K (represented as mTORactivity) levels were obviously up?regulated in MCF?7/5?Fu and T47D/5?Fu cell lines, and so do the FGF2 mRNA level and FGF2 protein level from culture medium. Moreover, FGFR inhibitor AZD4547 (4 nM) markedly reversed the chemo?resistance of MCF?7/5?Fu and T47D/5?Fu cell lines to 5?Fu and paclitaxel and down?regulated activation of FGFR?Akt?mTOR signal pathway. In agreement, FGF2 protein (10ng/ml) enhanced the chemo?resistance of MCF?7 and T47D cell lines to 5?Fu and paclitaxel and up?regulated activation of FGFR?Akt?mTOR signal pathway. Conclusion Activation of FGF2?FGFR?Akt?mTOR signal pathway promoted chemo?resistance of breast cancer cells.
