Repair of articular cartilage injury has always been a focus of medical study and sports injury study.With the application and development of molecular biotechnology,the role of growth factor has become more and more important in articular cartilage injury.This paper analyzes the difficulties in repairing articular cartilage injury.discusses the effect of transforming growth factor β1 and bone morphogenetic protein-2 on it as well as the mechanism under its repainng,and summanzes the existing problems.it can provide important data for future research.

OBJECTIVE:To elucidate the role of transforming growth factor-β and bone morphogenetic protein-7 in the reparation of knee cartilage by summarizing related studies,which can provide an important reference for further clinical applications.DATA SOURCES:The science online,ElsecierSD databases,Springer Link electronic joumals nets(1991-01/2009-06)was searched using key words of"Articular Cartilage Defects,Transforming Growth Factor-β,Bone Morphogenic Protein-7";simultaneously,the CNKI,Wanfang database,Tsinghua Tong Fang database(1991-01/2009-06)was searched with the same Chinese key words.Literature search was limited to English and Chinese languages.DATA SELECTION:Literature addressing repairing articular cartilage damage with growth factors was included,and the repeated papers were excluded.MAIN OUTCOME MEASURES:①Frecture healing.②Osteocyte proliferation.③Capacity of chonddfication.RESULTS:Received 95 computers seized in early literature,according to inclusion exclusion criteria,literature underlying growth factor,in particular the growth factor transforming growth factor-β and bone morphogenetic protein-7 in repaidng knee cartilagedamage was analyzed.Articular cartilage injury,with poor repair capacity,is more common in athletes.As soon as a permanent injury that generates lesions,it is difficult to treat by traditional treatment methods,which need to be solved in sports medicine.Transforming growth factor-β,an important factor regulating the formation of cartilage,stimulates or inhibits a variety of cells.By increasing the sensitivity of chondrocytes,transforming growth factor-β plays a central role in the process of repairing osteoarthdtis cartilage injury,regulates in vitro protein synthesis,but also affect on the induction of specific granulation tissues.Bone morphogenetic protein-7 can induces cartilage-specific collagen and mucin production by mesenchymal and wound areas,which has promotive effect on cartilage reparation.CONCLUSION:Transforming growth factor-β or bone morphogenetic protein-7 has certain effect on knee cartilage injury;however,whether the combination of them can promote reparation of articular cartilage injury needs to be explored.

Objective:To observe the effect of Fufang Congrong Yizhi Capsule on myristoylated alanine-rich C-kinase substrate (MARCKS) mRNA level in hippocampus of old dementia rats induced by ?-amyloid(1-40). Methods: Animals were divided randomly into young group, old group, sham operation group, model group, western medicine group and Chinese medicine group. Model, western and Chinese medicine groups received ?-amyloid (1-40) intracerebroventrical injection to build dementia animal model, and then Chinese and westein medicine groups received Fufang Congrong Yizhi Capsule and donepezil for 14 days, respectively. To observe changes of behavior and MARCKS mRNA under the effect of Chinese and western medicine by Morris test and RT-PCR test. Results: Learning and memory function of Chinese and western medicine groups were better than that of model group. MARCKS mRNA of model group was increased significantly, that of Chinese medicine group was decreased compared with model group. Conclusion: Fufang Congrong Yizhi Capsule can reduce the level of MARCKS mRNA in hippocampus of old dementia rats caused by ?-amyloid(1-40), through which it can improve the learning and memory function of the dementia old rats.

Doctors of past dynasties already understood deficiency of kidney essence,phlegm and blood stasis were important for dementia.As the increasing recognition about Alzheimer disease and the offer of 'toxin damaging brain vessel' hypothesis,we thought ?-Amyloid,the pathology of Alzheimer disease,had the character of damaging brain and marrow,so it belonged to internal toxin,internal toxin damaging brain and marrow was also the pathology of the disease.Deficiency of kidney essence was the precondition,insufficient brain and marrow and internal toxin damaging brain and marrow were the two causes of brain and marrow consumption and spirit dysfunction,which were the pathology of Alzheimer disease in Chinese medicine.

The fast transmission and large range of emergence of infectious diseases jeopardize human health, social and economic development, which is a great threat to global public health. World Health Organization for the new features of infectious diseases on theInternational Health Regulations was revised to help member countries improve the ability to respond to public emergencies. Our government promptly revised theCommunicable Disease Prevention Act, enacted a series of laws and strategies to promote the establishment of infectious disease surveillance and response systems. Chinese medicine was included in the country infectious disease prevention and control system. After nearly 10 years of development, the prevention and treatment of Chinese medicine on emergence of infectious diseases, the clinical medicine and research capacity of respond infectious diseases has been significantly improved, and become an important part of our system of infectious disease prevention and control.

OBJECTIVE: To investigate the cause, genetics, clinical features, pathological mechanism, diagonosis and treatment of the Giant pleomorphic adenoma of the parotid gland (GPA). METHOD: A case of GPA was reported and relevant literatures were reviewed. RESULT: GPAs were more commonly found in elderly patients, duration of more than 10 years, with a possible malignant degeneration. CT scan shows uneven density, different degrees of enhancement and clear boundary. Pathological examination shows that the composition of tumor tissue are epitheli al cells, myoepithelial cells and mucus. CONCLUSION GPA is an uncommon disease and is associated with human factors. The diagnosis of GPA is oriented by medical history, physical examination and imaging tests. The total resection of the tumor and preservation of the facial nerve is an effective way for the treatment of GPA.

OBJECTIVE: To investigated the effects of Src family kinases on the expression of mRNA and protein of Nav1.1 in spiral ganglion neurons. METHOD: RT-PCR and Western blot techniques respectively explored the level of expression of mRNA and protein of Nav1.1 in spiral ganglion neurons by Src family kinases inhibitor. RESULT: An application of the inhibitor of Src family kinases which was PP2 (10 micromol/L) and SU6656 (2 micromol/L) gived rise to the mRNA decreasing to 26% +/- 0.8% and 36% +/- 1.5% respectively (P < 0.05), and protein reducing to 39% +/- 12.5% and 53% +/- 1.7% severally (P < 0.05). CONCLUSION Administration of the inhibitor of Src family kinases could decrease the expression of mRNA and protein of Nav1.1 in spiral ganglion neurons.

OBJECTIVE: To investigate the relative factors of pharyngo cutaneou fistulas after larynx cancer and lower pharynx cancer surgery. METHOD: The clinical datas of 87 larynx cancer patients and lower pharynx cancer patients admitted were retrospectively analyzed. According to the type of postoperative complications all cases could be divided into pharyngo cutaneou fistulas group and no pharyngo cutaneou fistulas group. Thirty-eight kinds of factors,including age, clinical stage, plasma electrolytes level and type of procedure are in the multivariate analysis, and the variability indicators are in binary-regression analysis. RESULT: Eleven patients had pharyngo cutaneou fistulas (12.64%). Univariate analysis indicated that BMI, pre-operative serum potassium, operation time, cervical lymph dissection, post-operative prealbumin, post-operative hemoglobin, infection and delayed union of incision were the risk factors of pharyngo cutaneou fistulas (P < 0.05). Logistic stepwise regression analysis indicated that post-operative prealbumin and operation time were the independent risk factors. CONCLUSION To avoid pharyngo cutaneou fistulam, it is very necessary to correct electrolyte disorder and negative nitrogen balance. To shorten the operation time, to avoid incision infection and delayed union were helpfulness, too.
