Objective:To investigate the anti-gout capsule ( AGC) effect on acute gouty arthritis ( AGA) rat tumor necrosis factor-α(TNF-α)level.Methods: Selected 60 SD rats,were randomly divided into normal group,model group,colchicine group(0.8 mg/kg),AGC low dose group (0.3 g/kg) and AGC high dose group (1.2 g/kg),12 rats in each group,detected each group articular cartilage,serum and synovial fluid TNF-αcontent,observed rats ankle swelling.Results: The model group 24 h,48 h gait behavior scores were(2.57±0.43)point and(2.11±0.50)point,significantly higher than other groups (P<0.05);colchicine group,AGC low dose group and AGC high dose group 24 h,48 h gait behavior score were significantly lower than that of model group (P<0.05).The model group began to swell after modeling 2 h,reached the peak at 12-24 h.The rats in the modeling 72 h each period ,the model group ankle swelling rate were significantly higher than the normal group , the difference was statistically significant ( P<0.05 ) .Colchicine group 12 h,24 h and 48 h ankle swelling rate was significantly lower than that of model group ( P<0.05 ) ,AGC high dose group 12 h,24 h,48 h and 72 h ankle swelling rate was significantly lower than that of model group ( P<0.05 ) ,AGC low dose group ankle swelling rate was lower than that of the model group only in 24 h ( P<0.05 ) .The model group articular cartilage TNF-αexpression significantly increased compared with normal group ( P<0.05 ) ,but model group and colchicine group difference were no statistically significant ( P>0.05 );AGC high dose group and low dose group articular cartilage TNF-αexpression significantly decreased than model group ( P<0.05).The model group serum and synovial fluid TNF-αcontent were significantly higher than the normal group (P<0.05);colchicine group,AGC low dose group and AGC high dose group serum and synovial fluid TNF-αcontent reduced compared with the model group (P<0.05);AGC low dose group and AGC high dose group serum TNF-αwere(0.81±0.27)ng/ml and(0.79±0.31)ng/ml,lower than the colchicines group ( P<0.05 ).Conclusion:AGC can significantly improve the joint symptoms of AGA rats ,decrease AGA rats articular cartilage tissue ,serum and synovial fluid TNF-αlevel.

thymus.It is not clear why and how these distribution exist,which is possibly correlated to recruitment,homing,subset,and microenvironment of NK cells in each tissue or organ.

The mucosal tissues form the interface between the outside world and the sterile environment of the body.Innate immunity plays a critical role in the maintenance of mucosal homeostasis.Recently,a new subset of innate immune cells named NK-22 has been discovered to reside at tonsil and intestine both in human and mice.NK-22 cells share features with both natural killer (NK) cells and lymphoid tissue-inducing (LTi) cells.NK-22 cells express a variety of NK cell receptors and phenotypically resemble that of immature NK cells (iNKs).However,they are quite different from NK cells in function and development.NK-22 cells lack conventional NK cell cytotoxic function and produce IL-22 instead of IFN-?.It is currently considered that NK-22 cells are not a subset of NK cells.They develop from LTi cells and the development process depends on ROR?t and commensal microflora.NK-22 cells are involved in immune protection against the pathogen Citrobacter rodentium.The IL-22 secreted by NK-22 cells contributes to epithelial cell resistance to injury and mucosal tissue repair after microbial infection.

Based on a clinical and radiological study of radiation injuries of the bones in the 17 cases, the relationship between the osseous changes and the radiation dosage and between the time from radiation therapy and the onset of the radiographic osseous changes were discussed. The authors found that the degree of local skin infection might determine the type of its underneath osseous injuries, i. e. being either "septic" (osteomyelitic) or "aseptic" (bone atrophic) radionecrosis, and it might also determine the time when the osseous changes appeared on the radiogram. It was found that radiation injuries of the bone could be distinguished from bone metastases. The authors suggest that a regular X-ray follow-up of the bones that had received a heavy dose of radiation should be made in order to reveal bone atrophy as early as posible and to remind the patient to avoid any trauma and infection.

Objective:To analyze whether medical insurance and environment protective behaviors could alleviate the influence of environmental pollutions on individual health status.Methods:Using the data of CGSS(2010) to conduct the empirical analysis based on Logit model.Results:Residents' choice on medical insurance and environment protective behaviors could alleviate the damage of environmental pollutions on health.Compared with the young and middle-aged,the elderly effectively alleviated the damage brought by environment pollutions through participating medical insurance.Compared with the low-educated individuals the high-educated inviduals' choices for environment protective behavior could effec tively release the damages brought by environmental pollutions.Conclusion:The government should advocate environmental protective behaviors,provide full coverage of medical insurances to let individuals alleviate the damages of environmental pollutions by their rational choice.More emphasis should be paid to the damage of environmental pollutions on the elderly group and individuals with lower education.

Neonatal hypoglycemia is a common clinical disease.Hypoglycemia can lead to severe acute and long-term dysfunction of nervous system.The several aspects of neonatal hypoglyccmia such as the definition,diagnosis of brain injury,risk factors,treatment,detection method and long-term follow-up were reviewed.

Objective To investigate the optimum extraction of total flavonoids and baicalin in baical skullcap root. Methods Ultraviolet spectrophotometry was used to detect the content of total flavonoids, HPLC was used to detect the content of baicalin. With the test of extracting method, time, frequency, and adding water volume, the optimum extracting craft was determined. Results The best craft for extraction was:heating water for recirculation, setting extracting time for 1.5 h, extracting frequency for 3 times, and water volume for 8 times of baical skullcap root. Conclusion The optimized process for extraction are stable, reasonable and feasible.

Amino acids (AA) as substrates of gluconeogenesis could promote endogenous glucose production.Some AA can enhance insulin secretion. Recently,many studies have found that some AA can also activate mammalian target of rapamycin-S6 kinase 1 ( mTOR-S6K1 ) pathway,resulting in maintaining pancreatic β cell function on one hand,and on the other hand,inhibiting insulin signal transduction of insulin-sensitive cells and thus causing insulin resistance.

Neural stem cells are a study hot spot in neurobiological science and neurosurgery in the near future. The transplantation of neural stem cells already became a new way which be used for treating the injury and degenerative disease in the nervous system, because of the self-renewal and cell differentiation bionomics. However, how to get massive neural stem cells, which can be used in animal experiment and clinical application, has constrainted the development of stem cell technique.This article introduced the harvesting methods of embryonic stem cells, adult neural stem cells and mesenchymal stem cells, in order to lead cellular transplant treatment into clinical treatment plan by a safe and effective mode.

Based on concerns during stents manufacturing, the tubing purchase specifications of coronary stents have been proposed, and the key role of process inspection for judging the qualified tubing have been justified. By comparing the incoming inspection and the process inspection, it is concluded that the process inspection, as basis for optimizing tubing, is indispensable for selecting and confirming the tubing.
