Objective To observe the effect of total glucosides of peony on hypergammaglobulinemia of undifferentiated connective tissue disease(UCTD). Methods Fifty patients with UCTD were randomly divided into the treat-ment group (total glucosides of peony and hydroxychloroquine and thymosin) (n=30) and the control group (hydroxychloroquine and thymosin) (n=20). The changes between the two groups on hypergammaglobulinemia after treated for 3 months were compared. Results The two groups all had the IgG and IgA decreased, but the treatment group decreased more significantly. In addition, the treatment group had decreased RF. Conclusion Total glucosides of peony can improve the hypergammaglobulinemia of UCTD.

The air effect of disinfection was compared with undisinfected control group in terms of total number of germs.RESULTS Bacterial count of disinfected group was lower than that of undisinfected group(P

BACKGROUND: Basic fibroblast growth factor (BFGF) widely in human tissue participates in trauma repair of various tissues and is one of wound healing factors in the body. OBJECTIVE: To summarize the progress of BFGF in the fracture healing. RETRIEVAL STRATEGY: A computer-based online search of Pubmed Database was undertaken to identify the relevant articles on BFGF in the fracture healing published from January 2000 to December 2007 with the Keywords of "fibroblast growth factor 2 (basic fibroblast growth factor), fracture healing, regulation, signal transduction" in English. At the same time, Chinese relevant articles were searched in China Journal Full-text Database (CJFD) and Wanfang Database published between January 2000 and December 2007 with the same key words in Chinese. Exclusive criteria included articles with repetitive research and non-original study. LITERATURE EVALUATION: A total of 33 articles were collected about the distribution (3 articles), biological characteristics (3 articles) and the effect on the healing of bone fracture (27 articles) of BFGF. DATA SYNTHESIS: Bone healing is the process of regeneration after bone injury and the process of bone formation. BFGF can promote the cell migration by its chemotaxis and accelerate the healing by aggregating mesenchymal stem cells, macrophage and fibroblasts towards trauma region. Present animal studies on BFGF are deep and reports on clinical application are a few. Thus, the effect of BFGF is available. BGFG can affect bone formation by adjusting cell prolifeation and differentiation and changing the synthesis of cell products. BGFG not only can promote the bone growth, but also enhance the adhesion of osteoblasts and scaffold. CONCLUSION: The distribution and biological characteristics of BGFG have been recognized primarily. The further study on modulatory mechanism in the fracture healing of BFGF is carrying through. The bone restoration compounded by BFGF and its carriers is in the experiment and needs to be studied further.

Drug position is the unique clinical value in clinical doctors or patients and medical literature evidence is the important evidence for the effective delivery of drug position information to the users.The logistic relation of the basis for medical literature evidence linage construction with the search of clinical research evidence, selection and assessment of medical literature evidence and creation of medical literature evidence was thus systematically expounded in this paper in order to provide certain enlightenments for the relevant researchers.

Epigenetic regulation involved in eukaryotic gene expression plays an important role in the progression of colorectal cancer. Colorectal cancer epigenetics is evolved in DNA methylation which is associated with the activation of oncogene and inactivation of tumor suppressor gene. The potential reversibility of DNA methylation offers exciting opportunities for therapy and diagnosis of colorectal carcinoma.

Objective To investigate the clinical values of loop electrosurgical excision procedure (LEEP) in diagnosis and treatment of cervical intraepithelial neoplasia(CIN). Methods Fifty-two patients with cervical intraepithelial neoplasia underwent LEEP following cytology, colposcopy and multiple biopsies, were treated by LEEP. The cure rate, the operative time, bleeding volume and patients reaction of LEEP to the cervical intraepithelial neoplasia were investigated during the follow-up. Results The effective rate was 98.07 % in the patients treated by LEEP. The effective rate was 100 % in the patients in grade CIN Ⅰ or CIN Ⅱ by LEEP. No patients in grade CIN Ⅰ and Ⅱ had recurrence during the follow-up 1 year. The mean operative time was 7.8 minutes. The mean bleeding volume was 10 ml. No secondary bleeding and post-operative infection occurred. All these surgical specimens were checked successfully for pathology diagnosis. Conclusion The advantages to use the LEEP to manage cervical intraepithelial neoplasia include its simpleness to handle, short operative time,less bleeding, less vaginal discharge, safety, and high cure rate. LEEP can offer intact sample for pathological diagnosis. LEEP electrotome is a very ideal therapy for the cervical intraepithelial neoplasia, and can block the development of precancerosis to infiltrating carcinoma effectively.

Objective To evaluate retrospectively the efficacy of cistema magna plastic repair in the treatment of Chiari malformation complicated with syringomyelia Methods Fifty-one patients suffered from Chiari malformation complicated with syringomyelia were treated in our department from May 2004 to October 2009. Seventeen patients received cistema magna plastic repairment (the decompression of posterior cranial fossa, duraplastic repair,resection of hernia below cerebellar tonsil and separation of adherence of arachnoid membrane). Results Clinical symptoms disappeared or improved in 15 cases (effective rate of 90%). MRI showed tonsillar herniation disappeared,syringomyelia narrow. MRI showed cistema magna plastic repair, syringomyelia disappeared or significantly thinned and spinal cord subarachnoid space widened. Effective treatment obtained in 12 cases (effective rate 70%). Conclusions The efficiency of Cistern magna plastic repair treating Chiari malformation with syringomyelia is satisfied.

Differences in their pharmacognostic features, microscopic appearance of their powders and UV spectrums, can be used to differentiate Artemisia rupestris from its confusable Achillea millefolium. It is of value to identify them in actual practice.

Insulin resistance ,a key component of type 2 diabetes,is recognized as the pathological basis of the metabolic syndrome. H owever,its underlying mechanisms are still not fully understood.Recently,eleva ted levels of free fatty acids (FFA)have been observed in many insulin-resist ance states,which has gradually drawn attention.Not only do FFA interfere in se veral steps involved in glucose metabolism,but also play an important role in i nsulin signal transduction,resulting in decreased insulin-stimulated glucose t ransport. The thiazolidinediones,as insulin-sensitizing drugs,have entered th e market. A prominent effect of these agents is the lowering of circulating FFA levels and it is believed that targeting FFA metabolism may therefore offer wide r expectations in therapy for insulin resistance and type 2 diabetes.
