Traditional Chinese medicine (TCM) is a very practical subject, which has its unique theoretical system and clinical characteristics. In the course of clinical practice, the exact clinical efficacy is the key of existence and development. But the existing evaluation system is difficult to objectively evaluate the clinical efficacy of TCM. Therefore, how to objectively evaluate the clinical efficacy and get definitive evidence is the focus of the evaluation of clinical efficacy of TCM. Relative to modern medicine, TCM is more concerned about the changes of feelings and clinical symptoms of the patient in the course of the evolution of the disease. Soft targets mainly used for the evaluation of the clinical efficacy of symptoms and functional activity of the disease. The level in soft targets of processing technology is often used methods in clinical evaluation. But it has often produced the phenomenon which the results of the evaluation is mutual contradiction, which will ultimately affect the effect of evaluation of clinical efficacy of TCM. In order to better evaluate the clinical efficacy of TCM, in the process of adoption of soft targets, it clearly identify it's role, highlighting the characteristics of interventions on disease, and as much as possibly avoid the level in soft targets of processing technology to real assess clinical efficacy of TCM.

Aim To study and compare the pharmaco-kinetic parameters of roxithromycin under normoxic and hypoxic rats. Methods A highly effective and rapid ultra-performance liquid chromatography with tandem mass spectrometry ( UPLC-MS/MS) method with posi-tive electrospray ionization source was successfully de-veloped and validated for quantification of roxithromy-cin in rat plasma. Sprague-Dawley rats were randomly divided into the hypoxia and normoxic groups. Each rat obtained a single dose of roxithromycin with 10 mg · kg-1 via intragastric administration. The pharmacoki-netic parameter comparison between normoxic and hy-poxic groups was calculated by SPSS software using in-dependent sample t test method. Results The main pharmacokinetic parameters of roxithromycin between the normoxic and hypoxic rats were:the AUC(0-t) 7 576 and 3 761 μg·h·L-1 , MRT(0-t) 5. 6 and 7. 7 h, T1/2 3. 4 h and 3. 9 h, CL 1. 5 and 3. 0 L · h-1 · kg-2 , tmax3. 1 and 3. 4 h, Cmax 1 116 and 372 μg·L-1 , re-spectively. The levels of Cmax and AUC of roxithromy-cin in hypoxic rats were statistically lower than those in normoxic rats. Conclusion The exposure level of rox-ithromycin in hypoxic rats markedly decreased. Our re-sults may provide an important experimental basis to adjust the dosage for roxithromycin in hypoxic clinical practice.

OBJECTIVETo study the effect and mechanism of berberine (BER) on the proliferation and differentiation of adipocytes.

METHODSThe proliferation of 3T3-L1 pre-adipocytes was detected by XTT method. Lipid droplets accumulated in the cytoplasm of adipocytes in the differentiating process were observed by oil red O staining and quantified by colorimetry. The expressions of peroxisome proliferation activated receptor gamma (PPARgamma), CAAT/enhancer binding protein alpha (C/EBPalpha) mRNA and protein were detected by Real-time PCR and Western blotting respectively.

RESULTSIntervention with BER in concentration below 10 micromol/L for 24 h showed insignificant effect on the proliferation of adipocytes, as compared with that in the control group (P > 0.05); but that in concentrations 20, 40 and 80 micromol/L revealed significant suppressive effect; that in different concentrations acting for 48 h and 72 h could affect the proliferation and the effect displayed a dose-dependent manner, i. e. the higher the concentration of BER, the more apparent the suppression, showing significant difference as compared with those in the control group (P <0.05 or P <0.01). The pre-adipocyte treated with 10 micromol/L BER showed that the lipid droplets in the cytoplasm significantly lessened, so did the expression of differentiation related factor PPAR gamma mRNA as well as the expressions of C/EBPalpha mRNA and protein, as compared with those in the blank control group and the group intervened with rosiglitazone, the difference was significant (P < 0.05 or P < 0.01).

CONCLUSIONSBER can suppress the proliferation and differentiation of 3T3-L1 pre-adipocytes, reduce the accumulation of lipid drops in the adipocyte differentiating process, which may be associated with its effects in decreasing the expressions of adipocyte differentiation related gene PPARgamma, C/EBPalpha mRNA and protein. The study provides a basis for applying BER on the prevention and treatment of such metabolic related diseases as obesity.

OBJECTIVETo observe the effect of Bushen Huoxue Granule (BHG) on dopamine (DA) neurotransmitter and dopamine transporter (DAT) in the brain of patients with Parkinson's disease (PD) as an adjunctive therapy.

METHODSNinety-four PD patients were randomly assigned to two groups, 47 in each group. Madopar was given to all as the basic treatment group. The placebo was given to those in the control group while BHG was given to those in the treatment. The therapeutic course for all was three months. Before and after treatment DA levels in the brain of patients were detected by encephalofluctuograph (EFG) technique. Changes of DAT in the striatum of patients in the treatment group were detected by positron emission tomography (PET) and region of interest (ROI) analysis.

RESULTS(1) Before treatment the DA level was lower in the two groups than the normal value, showing significant difference (P < 0.01), but with no significant difference between the two groups (P > 0.05). After treatment the DA level obviously increased in the two groups, showing significant difference from that before treatment (P < 0.01). No significant difference existed in the DA level in the two groups when compared with the normal value (P > 0.05), but with significant difference between the two groups (P < 0.05). Better results were obtained in the treatment group than in the control group. (2) The DAT radioactive accumulation inside the striatum increased obviously in the treatment group after treatment. ROI analysis showed the total ratio of striatum/cerebellum before and after treatment was 1.86 +/- 0.32 and 2.61 +/- 0.53 respectively, showing statistical difference (P < 0.05).

CONCLUSIONBHG could improve the DA level of PD patients, and increasing DAT contents in the striatum, thus playing a role in effectively treating PD.
