The rule of law is the basic approach of realizing harmonic relationship between doctors and patients.Therefore,the law on medicine and health should be consolidated,and the rights and obligations of both parties should be specified.Meanwhile,the enforcement of law should be strict and civilized,while developing the legal awareness of the people to maintain their rights legally,and creating nice medical sequences and doctor-patient relationship in legal environment.

BACKGROUND:The bone metabolism of osteoarthritis is regulated by estrogen with osteoblasts, osteoclasts and cytokines, as wel as a number of regulatory pathways.
OBJECTIVE:To describe the role of estrogen and estrogen-related compounds for joint protection, repair of bone and cartilage cells, and inhibition of synovitis in osteoarthritis.
METHODS:Author researched PubMed, Embase, Elseveir database from 1992 to 2014, with the key words of“osteoarthritis, estrogens, matrix metal oproteinases, interleukins, tumor necrosis factor-alpha”. After the quality of the included studies was evaluation, valid data were extracted and analyzed.
RESULTS AND CONCLUSION:Estrogen can increase the expression of osteoprotegerin and nuclear factor-κB factor ligands in osteoblasts, inhibit bone resorption, prevent the onset and progression of osteoarthritis. Estrogen upregulates anti-osteoclast cytokines, downregulates pro-osteoclast factors, and contribute to regulate bone metabolism of osteoarthritis patients through bone morphogenetic protein and Wnt signaling. Estrogen promotes the adrenal cortex secretion of glucocorticoids and indirectly inhibits the production of matrix metal oproteinases by the hypothalamus-hypophysis-adrenal gland axis. Exogenous estrogen inhibits bone resorption, which may help to delay the development of osteoarthritis. Estrogen and estrogen-related compounds may inhibit the cartilage loss caused by synovitis and inflammatory factors in the late stage of osteoarthritis.

0.05),and the distribution of genotypes was in Hardy-Weinberg equilibrium.Data analysis showed Met326Ile variant did not impact on FIns,FPG,HOMA index,BMI and gene expression of PI3-K,though the expression of PI3-K gene was lower in type 2 diabetes than in control group.Conclusion The Met326Ile variant of the p85? regulatory subunit of PI3-K is likely to be functionally normal in type 2 diabetes and health people.

The worktable could reduce mercury pollution and its damage to the staff. The worktable facilitates the maintenance and detection of the sphygmomanometer, and thus is worthy popularizing clinically.

Objective To study the relationship between land use/cover structure and changes and risk of plague prevalence.Methods Chifeng,Aohan,Alukeerqin and Wengniute were selected as typical areas of Spermophilus Dauricus plague foci in Inner Mongolia,density of Spermophilus Dauricus,plague epidemic and land use data in 1986,1995,2000 were collected,and risk of plague prevalence was represented by the density of Spermophilus Dauricus and epizooty of Spermophilus Dauricus.The percentage of land type structure,change degree of integrated land cover,division index of grassland for plague suitable habitat were calculated with ArcGIS 9.3.The relationship between the land use,cover change and the plague epidemic were analyzed by the methods of comparative.Results From 1982 to 2000,the density of Spermophilus Dauricus was lower than 0.4/hm2 and no epizooty of Spermophilus Dauricus was observed both in Aohan Banner and Chifeng City,which indicated low risk of plague prevalence.Contrarily,from 1982 to 2000,the density of Spermophilus Dauricus was higher than 1.0/hm2,and epizooty of Spermophilus Dauricus was prevalent in Alukerqin Banner,which implied high risk of plague prevalence.In Wenguiute Banner,the density of Spermophilus Dauricus was lower than 0.3/hm2 from 1982 to 1990,after then showed a rising trend,reached higher than 1.0/hm2 in 1991,1995-1997,and epizooty of Spermophilus Dauricus was also monitored,which denoted high risk of plague prevalence;In 1986,1995 and 2000,the proportions of grassland of Wengniute Banner,Alukerqinqi Banner (51.36％,49.14％,48.28％;56.97％,57.48％,57.44％) were much higher than Chifeng and Aohan Banner (35.99％,33.24％,32.95％;38.94％,34.46％,31.31％),but those of arable land (16.81％,18.78％,20.22％;13.28％,14.92％,15.15％) were lower than Chifeng and Aohan Banner (39.73％,42.25％,42.67％;41.21％,43.99％,49.53％).The highest of comprehensively dynamic degree of land cover changes appeared in Aohan Banner,and it was 0.53 and 1.11 in 1986 vs.1995 and 1995 vs.2000,respectively,and the lowest in Alukeerqin Banner,it was 0.22 and 0.05 during those periods.The grassland division index in Alukeerqin Banner was the lowest,which was 0.29 in 1986,0.28 in 1995,and 0.29 in 2000.The grassland division index was higher and showed a upward trends in Aohan Banner,which was 0.57 in 1986,0.69 in 1995 and 0.71 in 2000.Conclusion There is a certain relation between risk of plague prevalence and land use/cover structure and changes.

Cerebral smal vessel disease (CSVD) accounts for 25 to 30% of al strokes. It is a main cause of vascular cognitive impairment. Because of cerebral smal vessels can not easily be directly observed and studied in vivo and on imaging, so the term CSVD is generaly used to describe a syndrome of clinical, cognitive, neuroimaging, and neuropathological changes, and not focus on the pathological changes of the smal vessel wal itself that caused these syndromes. This article reviews the advances in research on CSVD, particularly its pathological changes of vessel wals.
