Facing current situation of integrative medicine (IM), authors put forward that clinical and diagnosis program of IM could be carried out from clinical path, pathogenesis, treatment theory and philosophy, and so on, but with different integration degrees. Meanwhile, formulation of concrete program should be disease-targetedly set up, and adjusted from person to person, from place to place, from time to time. As for settled IM program , authors could evaluate it from whether Chinese medicine and Western medicine have formed complementary, synergistic, excitatory actions, and toxicity attenuation; whether more problems could be solved in efficacy, safety, practicability, and economy than previous single mode.

BACKGROUND: External preparations treatment of fractures in traditional Chinese medidne are mostly ordinary hard-paste, cream, ointment, which lack of modernized traditional Chinese medicine transdermal delivery systems, and the treatment has poor drug absorption and simple process. The treating procedure needs to be used repeatedly, which would affect fracture external fixation and lead to unsatisfactory therapeutic effect. In this Paler, the extemal treatment of traditional Chinese medidna was combined with advanced micro-nano-technology to develop a new medical complex functional materials-micron traditional Chinese medicine functional lining material, which is an organic combination of diaplasis, fixation and local drug remedy, which provides a better treatment for fractures. OBJECTIVE: To explore the effect of micron tradifional Chinese medicine functional lining material on the healing of fracture in rabbits, METHODS: After model preparation, rabbits were randomly divided into 4 groups: rabbits in the micron group were treated with micron traditional Chinese medicine functional lining material plus plaster external fixation; those in the traditional Chinese medidna control group were treated with ordinary Chinese medicine functional material plus plaster extemal fixation; those in the lining material control group were treated with ordinary lining material added plaster extemal fixation; those in the natural healing control group had no special treatments. The effect of fracture healing was evaluated by X-ray at 2, 4 and 6 weeks after modeling. The serum concentration of alkaline phosphatase, calcium and phosphorus was detected respectivaly before modeling and at 2, 4 and 6 weeks after modeling. RESULTS AND CONCLISION: ①X-rap examination:After 6 weeks the external was almost copletly absorbed and medullary cavity was completely recanalizad in the micron group, while fracture line disappeared and the external callus began to be absorbed and medullary cavity was not recanalized in the traditional Chinese medidne control group. Additionally, there were case of non-union stump hardening in natural healing group. ②Serum biochemistry:The activity of alkaline phosphatase reached a peak after 2 weeks in micron group, which was 2 weeks ahead of time compared with that in traditional Chinese medicine control group. And the peak concentration of alkaline phosphatase in micron group was higher than other groups. After 4 weeks serum calcium concentration started to fall significantly and phosphorus concentration started to rise significantly in micron group, as was statistically significant compared with other groups. After 6 weeks serum calcium concentration in micron group had fallen to normal level, while that in other groups was higher than normal. And phosphorus concentration in micron group increased significantly, which was statistically significant compared with natural healing group. The results demonstrated that micron feature traditional Chinese medicine lining matedat can enhance the activity of alkaline phosphatase, decrease the serum concentration of calcium and increase the serum concentration of phosphorus and the product of calcium and phosphorus, therefore, promote the healing of fracture, It shows that micron traditional Chinese medicine functional lining matedal plays a stronger effect on promoting the healing of fracture than that of ordinary Chinese medicine functional lining material.

OBJECTIVETo explore the mechanism of miR-124 inhibiting the proliferative activity of prostate cancer PC3 cells.

METHODSLuciferase reporter gene assay was used to examine the specific binding ability of miR-124 to PKM2 mRNA 3'-UTR. After miR-124 was transfected mimic to PC3 cells, the expression levels of PKM2 mRNA and protein were detected by real-time fluorescence quantitative PCR (qRT-PCR) and Western blot, respectively. The effects of miR-124 mimic and PKM2 siRNA on the proliferative activity of the PC3 cells were determined by MTT assay.

RESULTSThe expressions of PKM2 mRNA and protein were upregulated (5.12 +/- 0.35) times and (4.05 +/- 0.20) times respectively in the PC3 cells as compared with those in the RWPE-1 cells (P < 0.05). Luciferase reporter gene assay demonstrated that miR-124 targeted PKM2 3'-UTR. At 24 hours after transfection with miR-124 mimic, the PKM2 protein expression in the PC3 cells was downregulated (0.16 +/- 0.04) times (P < 0.05), while the PKM2 mRNA level was not changed significantly (P > 0.05), as compared with the control group. MTT assay showed that both miRNA-124 mimic and PKM2 siRNA could inhibit the proliferation of the PC3 cells, but the former exhibited a greater inhibitory effect than the latter. After transfection with miR-124 mimic and PKM2 siRNA, the cell growth rates were (66.20 +/- 5.10)% vs (82.10 +/- 6.35)% at 24 hours (P < 0.05) and (49.34 +/- 2.37)% vs (70.10 +/- 5.80)% at 48 hours (P < 0.05).

CONCLUSIONmiR-124 can suppress the proliferation of PC3 cells by regulating the PKM2 gene.

OBJECTIVETo observe and compare the protective effect of garlic oil against carbon tetrachloride (CCL)-induced acute liver injury.

METHODSThe experiments include 4 preventive groups and 2 therapeutic groups. In every preventive and therapeutic group, the mice were randomized into 6 groups with 15 each, including one negative control group, one solvent control group, one CCl4 model group and 3 garlic oil groups (25, 50, and 100 mg/kg body weight). Before given a single gavage of CCl4 (80 mg/kg), the mice were pretreated with garlic oil by gavage in preventive group 1 (30 days, once daily), preventive group 2 (5 days, once daily), preventive group 3 (ahead of 2 h, once), preventive group 4 (immediately, once) or the vehicle (corn oil, 10 ml/kg) in solvent control group. In therapeutic groups, the mice were gavaged garlic oil 2 h (once, in therapeutic 1) or for 5 days (once daily, in therapeutic 2) after administration CCl. After 24 h of the last administration, blood was collected and centrifuged at 2500 r/min at 4 degrees C for 10 min, and serum was removed to measure ALT and AST activities. The liver was dissected, weighed to calculate the liver coefficient (relative liver weight). At the same time, the liver samples were studied by histological examinations.

RESULTSCompared with negative group, the liver coefficient and the activities of ALT and AST in serum of model group were increased remarkably (P < 0.01). Compared with CCl model group, the liver coefficient and the activities of ALT and AST in serum were decreased significantly (P < 0.01) by garlic oil dose-dependently in each preventive group. Simultaneously, histological assessment showed that garlic oil effectively alleviated hepatocyte injuries induced by CCl4. Comparing the preventive effects of garlic oil in every group, it was better in preventive group 3 than others. However, all indexes and histological examinations in therapeutic group 1 did not show the difference with those of CCl4 model group. In therapeutic group 2, all indexes recovered after 5 d of CCl4 administration.

CONCLUSIONSGarlic oil can prevent acute liver injury induced by CCl4 and the effect is better in ahead of 2 h group than others.
