Objective To study the genome DNA methylation in rheumatoid arthirits(RA)and the re- lated factors of DNA methylation.Methods Twenty-first cases with RA and 20 controls were recruited to par- ticipate the study.Plasma Hcy,SAM,SAH,the MTHFR gene C677T polymorphism and the expression of LFA-1 in CD4~+T cells was measured in all patients and controls.Results①The SAM levels were lower sig- nificantly in RA groups than in controls.The SAH levels were higher significantly in RA groups than in con- trols.②There was significant inverse correlation between plasma Hcy level and SAM level(r=-0.932,P＜0.01). There was significant positive correlation between plasma Hcy level and SAH level(r=0.924,P＜0.01).③The expression of LFA-1 in CD4~+T cells was higher significantly in RA groups than in controls.There was a signif- icant positive correlation between LFA-1 expression level and Hcy level(r=0.557,P＜0.01),a significant in- verse correlation between LFA-1 expression level and SAM level(r=-0.651,P＜0.01).④The MTHFR gene mu- tation lead to dramatically increase of Hcy,SAH level and the expression of LFA-1 level in CD4~+T cells and genome DNA hypomethylation.Conclusion①Hypomethylation of genome DNA is found in most RA pa- tients.②The factors associated with genome DNA hypomethylation include MTHFR gene mutation and hyper- homocysteinemia.③The expression of LFA-1 in CD4~+ T cells is higer in RA groups than in controls,which re- lates to the DNA methylation level and the MTHFR gene C677T polymorphism.

This study taking gestodene (GEST) as a model, investigated the factors affecting reservoir-type intravaginal ring (IVR)'s drug release. This paper reported a gestodene intravaginal ring of reservoir design, comprising a gestodene silicone elastomer core encased in a non-medicated silicone sheath, separately manufactured by reaction injection moulding at 80 degrees C and heating vulcanization at 130 degrees C is reported. The test investigated the factors affecting drug release through a single variable method, taking the drug release rates of 21 days as standards. When changing the thickness of the controlling sheath outside, the ratio of the first day of drug release and mean daily release (MDR), named the relatively burst effect, is closing to 1 with the thickness of controlling sheath increasing, while the 1.25 mm sheath corresponding to 1.04 controlled the burst release effectively; a positive correlation (r = 0.992 2) existed between the average drug release (Q/t) and drug loading (A) within a certain range. The C6-165 controlling sheath with high solubility of GEST is easier to achieve controlled release of the drug; GEST crystalline power is more effective to implement controlled release of drugs among difficent states of the drug. A 1/4 fractional segment core gives a relatively burst effect of 1.76, while the 1/1 and 1/2 are 1.93 and 1.87 separately, at the same drug loading, concluding that use of a fractional segment core would allow development of a suitable GEST reservoir IVR. In summary, GEST reservoir-type IVR could be adjusted by the thickness of controlling sheath, the loading of drug, the material properties of controlling sheath, the dispersion state of drug, the additive composition and structure of intravaginal ring, to control the drug release behavior and achieve the desired drug release rate.

Objectives:To observe the supporting effect of blenderized diet on the nulritional statusin the old patients. Methods:Twenty four patients were given blenderized diet made in our department as nutrition support.The nutritional assessments were preformed before and after the support. Results:The serum levels of albumin and phosphorus and the total lymphocyte count were increased after the support( P

Objective To discuss the aged people N-terminal pro-B-type natriuretic peptide (NT-proBNP)changes in thyroid function disorder and its correlation.Methods With electrochemical luminescence analyzer,detected serum NT-proBNP lev-el 38 patients with hyperthyroid heart disease,68 patients with hyperthyroidism,31 patients with hypothyroidism,and 43 ca-ses of healthy controls.Compared each groupserum NT-proBNP level of older population with middle-aged people,and anal-ysied the correlation.Results The serum NT-proBNP level of Hyperthyroidism heart group,hyperthyroidism,hypothyroid-ism group and normal control group were 827.61±626.13,107.18±54.46,162.94±134.14,68.76±39.21 pg/ml,respec-tively.The serum level of HT-pro BNP.Hyperthyroidism group,hyperthyroidism,hypothyroidism group compared with nor-mal control group,there were statistically significan(t = 7.458,4.312,3.794,P = 0.000,0.000,0.001).Hyperthyroidism heart,hypothyroidism with hyperthyroidism group serum level of NT-proBNP comparison there was statistical significance(t=7.078,2.232;P = 0.000,0.032).Hyperthyroidism heartgroup,hypothyroidism group and normal control group older population was higher than the level of serum NT-proBNP middle-aged,difference was statistically significant (t=-3.216,-2.510,-2.653;P =0.007,0.016,0.014).Hyperthyroidism group of elderly serum NT-proBNP level higher than that of middle-aged people,but there was no statistically significant difference (t=-0.140,P =0.890).Multiple regression analy-sis in hyperthyroidism group serum levels of NT-proBNP and FT4 had positive correlation (r=0.224,P =0.033)and hypo-thyroidismgroup serum levels of NT-proBNP and T3 had negative correlation (r=-0.363,P =0.022).Conclusion Thy-roid dysfunction in elderly people for the level of serum NT-proBNP had significant influence.Auxiliary disgnosis and cura-tive effect observation of the serum level of NT-proBNP in people with different thyroid functional status has certain clinical value.
