ABSTRACT
As one of the pathogenic mechanisms contained in The Inner Canon of Yellow Emperor （《黄帝内经》）， “disease with latent pathogen induced by a new pathogen” means that the induced new pathogen resulted to a combination of the latent previous pathogen and the new pathogen， which caused the disease. Based on this， it is believed that the change of “nodule-cancer transformation” of pulmonary nodules is actually based on the deficiency of original qi， and the new pathogen induces the latent pathogens like phlegm coagulation， qi stagnation， blood stasis， toxicity， so healthy qi can not drive the pathogens out， and the long-time detention generated into cancerous turbidity， and deve-loped into cancerous tumour at the end. Therefore， based on the three-stage treatment of unformed cancer， dense cancerous toxin， and developed cancer， the clinical practice applied six methods of clearing， expelling， dissipating， tonifying， harmonizing， and transforming， taking into account both the manifestation and root cause， moving the treatment window of pulmonary nodules forward， attacking the pathogens when the toxin was not yet overbearing， supporting the healthy qi before declining， delaying the process of nodules-cancer transformation， and providing ideas for the prevention and treatment of pulmonary nodules “nodule-cancer transformation” in traditional Chinese medicine.
ABSTRACT
Objective To investigate the mechanism of inducing production of vascular endothelial growth factors (VEGF) by recombinant human S100 calcium binding protein A4 (rhS100A4) in rheumatoid arthritis fibroblast-like synoviocytes (RAFLSs).Methods Synovial tissue was sampled from the patients with rheumatoid arthritis (RA) undergoing knee arthroplasty for in vitro culture of RAFLSs.CCK-8 assay was conducted to detect the effect of rhS100A4 and the effect of its interaction with Rapamycin (Rap),an inhibitor of mammalian rapamycin target 1 (mTORC1) signaling pathway,on the proliferation of RAFLSs.The effects of rhS100A4 and its interaction with Rap on the expression of VEGF in RAFLSs were detected by immunofluorescence.After rhS100A4 and its cooperation with Rap stimulated the conditioned medium (CM)produced by RAFLSs,the effect of CM on formation of lumen in human unbilical vein endothelial cells (HUVECs) in vitro was observed to detect the angiogenic ability of rhS100A4.Western blot was used to detect the effect of rhS100A4 on the phosphorylation of downstream ribosomal protein S6 (S6) in the mTORC1 signaling pathway in RAFLSs and to analyze the effects of rhS100A4 and Rap on phosphorylation of S6 protein and expression of VEGF protein in RAFLSs.Results rhS100A4 promoted cell proliferation and expression of VEGF protein in RAFLSs,and the CM formed by rhS100A4 promoted HUVECs to form blood vessels in vitro.Rap inhibited the above biological effects of rhS100A4,rhS100A4 activated the downstream protein S6 in the mTORC1 signaling pathway in RAFLSs cells to increase their phosphorylation levels.The effects of rhS100A4 on the phosphorylation of S6 protein and on the expression of VEGF protein in RAFLSs were inhibited by Rap.Conclusion rhS10OA4 promotes production of VEGF in RAFLSs by activating the mTORC 1 signaling pathway.

ABSTRACT
BACKGROUND:Atorvastatin has been shown to reduce bone loss and fracture, but its effects on implant osseointegration remain unknown. OBJECTIVE:To investigate the effects of atorvastatin on implant osseointegration in osteoporotic rats and the underlying mechanisms. METHODS:Forty-eight Sprague-Dawley rats were randomized into sham-surgery, ovariectomy, and atorvastatin (10 and 20 mg/kg per day) treatment groups, respectively. Al rats received ovariectomy and implant surgery except those in the sham-surgery group. Bone mineral density of the lumbar vertebra, osseointegration ratio and pul-out strength of implants were measured after 12-week treatment.Levels of bone formation and resorption markers in osteoblasts treated with atorvastatin were determined by ELISA. Wnt pathway-relatedgene expression was detected by RT-PCR. RESULTS AND CONCLUSION:Bone mineral density, osseointegration ratio and pul-out strength of implants were significantly increased in 20 mg/kg per day of atorvastatin treatment group compared with ovariectomy group (P< 0.05). Levels of alkaline phosphatase, osteocalcinand osteoprotegerinwere significantly increased in osteoblasts treated with atorvastatinin vitro(P<0 .05), and the level of osteoclast differentiation factor RANKL was significantly inhibited (P< 0.05). Meanwhile, atorvastatin significantly promoted the mRNA expression of low-density lipoprotein associated protein 5and β-catenin, and inhibited the mRNA expression of dickkopfWnt signal pathway inhibitor 1and sclerostin. Our results suggest that atorvastatin promotes implant osseointegration in osteoporotic rats by activating Wnt/β-catenin signal pathway.

Shuganyishen formula could reverse resistance to TAM. Conclusion Patients with LuminalA and LuminalB metastatic breast cancer benefit from Shuganyishen formula, which maybe related with its reverse resistance to endocrine therapy.
ABSTRACT
BACKGROUND: Though there were many experiments addressing repairing osteochondral defects before, faulty restoration occurred at coupling interfaces. OBJECTIVE: To investigate the feasibility of repairing of osteochondral composite defects in rabbit knees with animal-origin osteochondral scaffold combined with bone marrow mesenchymal stem cells (BMSCs)/chondrocytes.METHODS: New Zealand white rabbits were randomly divided into the experimental, control and blank groups and prepared for unilateral knee joint osteochondral defects. Animal-origin osteochondral scaffold combined with BMSCs/chondrocytes, animal-origin osteochondral scaffold and no material was implanted to repair the defects in the experimental, control and blank groups, respectively. Healing condition was evaluated by gross observation, hematoxylin-eosin staining, and toluidine blue staining at 4, 8, and 12 weeks after operation. RESULTS AND CONCLUSION: At 12 weeks after operation, gross observation showed the defects were repaired completely without local depression and the regenerated tissues were fused with surrounding tissues in the experimental group. Hematoxylin-eosin staining and toluidine blue staining revealed that there were many new hyaline cartilages in the cartilage defects in which columnar cells were lined well and cartilage lacuna was obviously, also, there were many bony tissues in the bone defects. The regeneration cartilage, the underlying subchondral bone and host bone were coupled completely. The toluidine blue positive rate and histologic scores of the experimental group were superior to those of the control and blank groups (P < 0.05). It is demonstrated that animal-origin osteochondral scaffold combined with BMSCs/chondrocytes is an ideal method to repair defects between cartilage and the underlying subchondral bone.
ABSTRACT
BACKGROUND: The development of cartilage tissue engineering provides novel ideas for treatment of articular cartilage defects and implements construction of tissue-engineered cartilage in vivo.OBJECTIVE: To investigate the feasibility of constructing tissue-engineered osteochondral composite through bone marrow stem cells(BMSCs) cultured on the poly(lactide-co-glycolic acid) (PLGA), which was modified with collagen and cellular growth factors.METHODS: PLGA was made by phase separation technique, composited with collagen Ⅱ, basic fibroblast growth factor, and transforming growth factor-β1. The BMSCs of passage 3 were cultured on the above scaffolds. Thirty-six SD rats were randomly divided into experimental, control, and blank groups. These three groups received implantation of BMSCs composited with growth factors and collagen-PLGA, implantation of BMSCs composited with collagen-PLGA, and implantation of collagen-PLGA into the muscle, respectively. At 4, 8, and 12 weeks after surgery, cell directional differentiation and growth were examined by gross observation, hematoxylin-eosin staining, toluidine blue staining, collagen Ⅱ staining, and scanning electron microscope.RESULTS AND CONCLUSION: Gross observation showed that there were many chondroid tissues in the experimental group and fibrous tissues in the control and black groups. Stainings and electron microscope revealed that many chondroblasts and a few osteoclasts appeared in the composite of the experimental group. Toluidine blue and collagen Ⅱ stainings were positive in the experimental group and negative in the control and blank groups. These findings demonstrate that PLGA modified with collagen had a good cellular compatibility. BMSCs cultured on PLGA, which was modified with collagen and cellular growth factors, can construct the tissue-angineered osteochondral composite in rats.
ABSTRACT
In addition to kill tumor cells through direct cytotoxicity, the immunomodulatory activity is another facet of chemotherapy. The major molecular mechanisms of immunogenicity of cytotoxic drugs are elimination of CD_4~+ CD_(25)~+ regulatory T cells or Myeloid-Derived Suppressor Cells, and sensitization of tumor cells to immune effectors through modulation of death receptor expression. These studies provide scientific evidence for combinatorial treatments including vaccines and Traditional Chinese Medicine for cancer therapy.
ABSTRACT
Objective The prospective study was trying to explore the altering tendency of plasma concentration of E2, P and PAS after TCM intervention for post-surgery breast cancer patient who received endocrine therapy (tamoxifen).Methods By randomization, parallel, coincidence measures and the lab. technologies of AXSYM registered at Abbott lab. in the USA, plasma concentration of E2, P and FAS were tested before and after treatment. Results The results of biochemical test of plasma E2, P and FAS concentration of the two arms showed no significance difference before and after the intervention,indicating the side effects relating to TAM had nothing to do with plasma E2, P and FAS level. Conclusion It could be predicable that there must be some other by-pass ways initiating breast cancer rather than the way directly altering the level of plasma concentration of E2, P and FAS.
