Bone Marrow Mesenchymal Stem Cells (BMSCs) are ideal seed cells for cell therapy,which have been through many long-term studies of in vitro and animal disease model treatment and have been widely used in preventing and treating a variety of clinical diseases caused by aging and other damage,including bone injury and regeneration,neural degenerative and injury,myocardial injury,liver cirrhosis,diabetes,lung disease and so on.BMSCs application in the treatment of orthopaedic disease is the most common and effective.By retrospective literature review,we summarize the BMSCs transplantation application in Orthopaedic disease treatment.As an ideal cell source,BMSCs was first applied in bone tissue engineering,mainly used in the treatment of long bone defect and bone nonunion;Recently,the research trends of clinical BMSCs application turned to treat degenerative diseases and genetic disorders because of its great potential,including osteoarthrits,femoral head necrosis,disc degeneration,spinal cord injury,knee varus,osteogenesis hypoplasia,hypophosphatasia and so on.The safety and efficacy of BMSCs treatment are the key issues in clinical cell therapy.There is no side effects and complications after BMSCs treatment,prove its clinical application is safe.But due to type and degree of disease and individual differences,therapeutic methods including injection method,effective concentrations,treatment window selection,cycle and therapeatic effects have a bigger difference.There is still no uniform of recognized operation standards for the treatment of the same type of disease.So BMSCs transplantation requires effective control during whole medical process and its application in orthopedic diseases is still lack of large-scale multicenter clinical study.Therefore,this review focuses on induction,summary and analysis in the research status of BMSCs in bone disease treatment,and provide new ideas and methods for BMSCs transplantation in orthopaedic disease prevention and treatment.

Colorectal cancer is a common malignant tumor of digestive tract, and the risk of inflammatory bowel disease developing into colorectal cancer is significantly increased. Immune signaling pathways NF-κB, IL-6/STAT3, COX-2/PGE2, IL-23/Th17 and TLRs have been confirmed to promote the transformation from colitis to colorectal cancer. NOD2 and intestinal microbes also participate in the regulation of inflammation mediated carcinogenesis. Chronic inflammation is a potential risk for colorectal cancer, and anti-inflammatory drugs may play a chemical preventive role. In this review, we summarize the signaling pathways involved in inflammation-associated colon carcinogenesis and evaluate the chemoprophylaxis of colon cancer.

OBJECTIVETo evaluate the clinical effects of arthroscopic reconstruction of anterior cruciate ligament (ACL) and minimally invasive reconstruction of posteromedial corner (PMC).

METHODSThere were 22 cases of ACL and PMC tear were performed with reconstruction from March 2012 to February 2014. The patients were 29.4 years old on average, including 8 males and 14 females. ACL reconstruction was performed under arthroscopy and PMC reconstruction was performed minimally invasively through the ACL incision. The stability of knee was assessed by anterior drawer test,Lachman test,vulgus stress test and Slocum test. The function of knee was assessed by Lysholm score and Tegner activity rating. MRI of knee was checked 12 months after operation.

RESULTSThe stability tests of all patients were negative at 2 and 6 months after operation, and there was one positive case in anterior drawer test and another positive case in vulgus stress test at 12 months after operation. Lysholm score of all patients 12 months after operation was 96.8 +/- 6.8, which was significantly better than 32.0 +/- 11.2 before operation. Tegner activity rating of all patients at 12 months postoperatively was 6.1 +/- 0.9, which was significantly better than 0.9 +/- 0.5 before operation. It showed the grafts were very well in the MRI 12 months postoperatively.

CONCLUSIONArthroscopic ACL reconstruction and minimally invasive PMC reconstruction can restore the stability of knee.

The main clinical symptoms of Parkinson disease (PD) are resting tremor, muscle rigidity and bradykinesia. There is currently no effective treatment for PD, and dyskinesia symptoms affect the quality of life of patients with PD. The Chinese medicine therapy used for reinforcing kidney and activating blood circulation in treatment of PD was reported to achieve good clinical effects.

ObjectiveTo clone TCF4 (T cell factor 4) gene and construct its eukaryotic expression vector. MethodsThe total RNA was extracted from the aggregated human dermal papilla cells. The full length cDNA encoding TCF4 was obtained by RT- PCR, digested by restriction enzyme, then inserted in the eukaryotic expression vector pcDNA3.0. The sequence and reading frame were confirmed by two restriction enzymes and sequencing. The recombinant vector TCF4/pcDNA3.0 was stably transfected into dermal papilla cells, and the expression changes of TCF4 gene were detected. ResultsTCF4 gene was cloned from dermal papilla cells and its eukaryotic expression vector was constructed. After the identification and sequencing, the reconstructed plasmid was confirmed containing the correct and full nucleotide sequence of TCF4 gene. After stable transfection, the mRNA and protein level of TCF4 gene were up-regulated in dermal papilla cells and the proliferation of dermal papilla cells was promoted. ConclusionThe expression vector TCF4/pcDNA3.0 was constructed successfully and could be expressed in the dermal papilla cells. TCF4 gene can promote the proliferation of the dermal papilla cells.

Objective To investigate the diagnostic value of low field MRI for adenomyosis. Methods MRI features of adenomyosis pathologically proved in 18 cases were retrospectively analysed.Results 15 cases were diffusive adenomyosis,the junctional zones of uterus were exteusive thickened to 12.0～32.6 mm,mean 16.2 mm,diffusive high signal intensity distributed over in myometrium which was low signal intensity in 11 cases,it was typical “snowing sign”,lower signal intensity in the myometrium in another 4 cases on T 2WI and fat-suppression imaging. A little high signal intensity was found in 6 cases on T 1WI. 3 cases were focal adenomyosis(adenomyoma), 4 lesions totally. The adenomyoma’s boundaries were not distinct and their shapes were roundish or irregular. The lesions were low signal intensity or diffusive high signal intensity distributed in the low signal intensity fields on T 2WI and fat-suppression imaging. A little high signal intensity was found in 2 lesions on T 1WI. Conclusion T 2WI and fat-suppression imaging of low field MRI are very useful techniques of the diagnosis of adenomyosis.
