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 investigate the effects of garlic oil (GO) against the peroxidation damage of rat nerve tissue and the peripheral motor neuropathy induced by 2, 5-HD.

METHODSMale Wistar rats were divided into four groups, with 10 in each group. The model group, and low and high doses of GO groups were administrated with 2, 5-HD (ip, 300 mg/kg), respectively; The control group was treated with sodium chloride, five times per week for six weeks. Pretreatment with GO gavaged (40 mg/kg or 80 mg/kg) started one week be-fore 2, 5-HD treatment, and lasted to the end of the experiment. Neurobehavioral indexes were examined at the zero, second and fourth week. At the end of the experiment, the scores of the gait, and the concentration of MDA and GSH, the level of TAOC and the ability of inhibition of.OH in cerebrum, spinal cord and sciatic nerve were examined.

RESULTSCompared with the zero week, except of the control group rats, the hind limb landing foot splay of three groups rats decreased by 44%, 50% and 49% at the fourth week, respectively without significant difference. The threshold value of balance in model, GO low and high doses groups rats decreased by 30%, 45% and 68% at the fourth week, respectively, and lower than the control group rats (P < 0.01). GO low and high doses groups rats showed the serious abnormality at the fourth week, before one week of the model group rats. The scores of gait of model, and GO low and high doses groups rats increased significantly compared with control group rats, and the GO high dose group rats were higher than model group rats (P < 0.05). Increase of the concentration of MDA, and decrease of the level of the ability of inhibition of.OH were induced by 2, 5-HD in cerebrum, spinal cord and sciatic nerve. The concentration of MDA increased, and the level of the ability of inhibition of.OH decreased (P < 0.05 or P < 0.01), respectively. The results showed that the concentration of MDA decreased, and the level of the ability of inhibition of.OH induced by GO in cerebrum, spinal cord and sciatic nerve increased, the concentration of MDA of GO low doses group rats decreased, the level of the ability of inhibition of.OH increased, the concentration of MDA of GO high doses group rats decreased (P < 0.01) respectively, and the level of the ability of inhibition of.OH increased (P < 0.01) in nerve tissue.

CONCLUSIONGO has antagonist effect on the 2, 5-HD induced peroxidation damage, but can not improve the function of the peripheral motor nerve, indicating that the lipid peroxidation does not play an important role in 2, 5-HD neurotoxicity.

OBJECTIVETo investigate the dynamic changes of neurofilament contents in rat's spinal cord induced by 2, 5-hexanedione (2, 5-HD), and explore the molecular mechanism of n-hexane neuropathy.

METHODSMale Wistar rats were administered at a dosage of 400 mg/kg/day 2, 5-HD for 2, 4 and 8 weeks respectively. HD-induced neurological defects were detected and quantified using gait score, and the relative lev-els of NF-H, NF-M, and NF-L in spinal cords of rats were determined by Western Blotting.

RESULTSExposure to 2, 5-HD produced progressive gait abnormalities, which suggested that the rat model of 2, 5-HD-induced neurotoxicity was established successfully. Western-Blotting results showed that NFs content in spinal cord demonstrated a progressive decline as the intoxication continued. In the supernatant fraction, compared to the controls, NF-H con-tent decreased by 15.7%, 57.0%, and 58.0% respectively after 2, 4, and 8-week treatment with 2, 5-HD (P < 0.01); accordingly, NF-M decreased by 36.0%, 61.3%, and 65.2% respectively (P < 0.01); NF-L decreased by 20.8%, 43.9%, and 44.3% respectively (P < 0.01). In the pellet fraction, the contents of NF-H in groups of 4 and 8 weeks' exposure to HD decreased by 35.6% and 43.2%, respectively (P < 0.01), and those of NF-L decreased by 26.4% and 42.1%, respectively (P < 0.01) when compared to the control. Further-more, NF-M contents in groups of 2, 4 and 8 weeks' exposure decreased by 23.3%, 33.9%, and 63.7% respectively (P < 0.01). The NFs level in spinal cords was highly correlated with gait abnormality of treated rats as the intoxication went on. Multiple correlation coefficients of NF-H, NF-M, and NF-L content with gait score of HD-treated rat were 0.8912, 0.9282 and 0.8981 (P < 0.01) respectively.

CONCLUSIONThe declines of NFs are high-ly related to neurobehavioral abnormality of 2, 5-HD-treated animals, and involved in the development of n-hexane neuropathy.
