In order to investigate the comprehensive quality differences of the seeds harvested in different growing time, and offer theoretical guide for the optimization of seeds' production technology, we analyzed the apparent size, 1 000-grain weight, water absorbency, germination indexes, postharvest embryo rate change, relatively contents of coumarins and the yield of single plant of its seeds of different harvesting time, and compared their comprehensive quality by Topsis analysis. The results showed that there existed obvious differences in yield and quality between seeds of 3 harvesting times. While the harvesting time postponed, the yield of single plant raised, and the shrunken seeds rate decreased, the quality of seedlings increased, while the contents of coumarins showed a steady increase, and the germination rate decreased. The comprehensive quality of the seeds harvested in the black ripe time rank the first place, followed by the brown ripe time and the yellow ripe time. As the harvesting time delays, the seeds' comprehensive quality increases, therefore, we could put off the seeds' harvesting time properly for the high efficient seed production.

Objective The surgery time for patients with infective endocarditis (IE) has been transformed.It has been supported that,for the patients with surgical indications,the surgery time should be as early as possible to improve the clinical outcome.The purpose of the research is to identify whether the patients with IE could get further benefit from early surgery.Methods Between June 1996 and July 2011,135 IE patients'data has been collected retrospectively,all of whom were verified through the modified Duke categories.The patients were devided into group A( the new therapeutic schedule group after 2008 ) and group B( the traditional therapeutic schedule group before 2008 ) by the year of 2008.The end points of observation were death associated with IE,cardiac failure,embolism,and re-infection.The comparison between the groups was by means of non-parameter rank and inspection test,variance analysis,t test,chi-square test,fisher exact test.The outcome comparison between the groups was via the Kaplan-Meier survival analysis.Results There were no significant differences in baseline data between the groups.No survival differences could be observed via the Kaplan-Meier analysis( Log Rank P =0.189).During the following-up visit,compared with the patients in group B,the mortality in group A is lower(9.4% vs.23.0%,P=0.016),the incidence of heart failu re was less in group A (5.4% vs.26.2%,P <0.001 ).No differences could be found in re-infection between the two groups(0 vs.4.9%,P =0.112 ). More patients in group A underwent surgery (67.6% vs.32.8%,P <0.001 ).Conclusion The new therapeutic sehedule of IE coull reduce the mortality rate and promote the cardiae funetion.The incidence of re-infeetion didn't increase.

5 fold) were noted.Six significant differential proteins in gel were identified by LTQ-ESI,e.g.endoplasmin precursor,acidic leucin-rich nuclear phosphoprotein 32 family member A,serotransferrin precursor,stress-70 protein precursor,fibronectin precursor,complement C3 precursor,fibrinogen gamma polypeptide.CONCLUSION: The protein profile of apoE-/-/LDLR-/-mouse liver exhibits significant difference compared to that of WT mice.The results imply that lipid metabolism relative polygenetic mutation contributes to the alteration of mouse liver protein expression profile,especially that lipid metabolism related perhaps participates in dysfunction in lipid metabolism during atherogenesis.

AIM: To investigate the influence of serum apolipoprotein (apo) CII concentrations on the distribution of serum high-density lipoprotein (HDL) subclasses. METHODS: Serum HDL subclasses in 247 subjects were determined by two dimensional gel electrophoresis-immunodetection. RESULTS: With the increase in serum apolipoprotein CII levels, age, BMI, the contents of TG, TC, apoB100, apoCII, apoCIII, apoE, preβ_1-HDL, preβ_2-HDL, HDL_3b and HDL_3a increased significantly, but the contents of HDL-C, HDL_(2a) and HDL_(2b) decreased remarkably. The contents of preβ_1-HDL increased with the rise in apoCII and apoA I levels, whereas the content of HDL_(2b) increased with the rise in serum apoA I level in the same apoC II group, but decreased with the increase in serum apolipoprotein CII level in the same apoA I group. With the increase in the ratio of apoCII/ apoCIII, the content of preβ_1-HDL elevated, but the content of HDL_(2b) decreased. The correlation analysis illustrated that the apoCII level was positively correlated with preβ_1-HDL (r=0.186, P<0.01), but inversely correlated with HDL_(2b) (r=-0.149, P<0.05). The apoA I level was positively associated with all HDL subclasses (r in the range of 0.349-0.587, P<0.01). In addition, the apoCIII level was positively correlated with preβ_1-HDL (r=0.184, P<0.01) and preβ_2-HDL (r=0.178, P<0.01), while the apoE level was positively correlated with HDL_(3a) (r=0.040, P<0.05). The apoB100 level was inversely correlated with HDL_(2a) (r=-0.102, P<0.05). CONCLUSION: The particles of HDL show a general shift towards smaller size with the increase in apoCII levels, indicating that the maturation of HDL is abnormal. Whereas the contents of apoA I level correct the effect of apoCII on the distribution profile of HDL subclasses. The ratio of apoCII/apoCIII might also been taken as one of the indexes reflecting the distribution profile of serum HDL subclasses.

Objective To investigate the proliferation characteristics of fibroblast like synovial cells (FLS)in osteoarthritis in vitro and the mechanism of the immnnosuppressive effect of T-614 [N-(3-formy- lamino-4-oxo-6-phenoxy-4H-chromen-7-yl)methanesulfonamide ] on them.Methods FLS of OA and non- inflamed synovium(NS)were cultured and identified in vitro in the presence or absence of T-614.After incu- bation,the survival fraction(SF)of FLS was evaluated by MTT,cell cycle was observed using fluorescence - activated cell sorting(FCS)method and the expression of c-fos and COX-2 mRNA was examined by RT- PCR in FLS of OA patients.Results No statistically significant difference was noted between the OA and NS FLS in proliferation ability and cell cycle.High dose T-614 suppressed FLS SF obviously in OA and NS sta- tistically(P<0.05),whereas the inhibition degree was not different between the two kinds of FLS.The agent induced cell apoptosis and reduced the accumulation of c-fos mRNA in OA-FLS at dose 1000 ml/L,prolonged G_1 term and shortened S term at dose 200 ml/L.The expression of COX-2 mRNA in OA FLS was suppressed obviously by T-614 at dose 1000 ml/L.Conclusion OA FLS do not display a distinct activated unlimited viability compared with NS cells,without stimulated by proinflammatory cytokine in vitro.High dose T-614 moderately inhibits the proliferation and differentiation of FLS,directly affects gene of the c-fos and COX-2 expression in OA,which may contribute to its immunosuppressive effect on OA'synovitis.

Objective To investigate the proliferation and differentiation characteristics of fibroblast like synovial cells(FLS)in rheumatoid arthritis(RA)in vitro and the mechanism of the immunosuppressive effect of differentiation inducers, such as all trans retinoid acid(ATRA), ealcitriol [1,25(OH)_2D_3] and dexamethasone(DEX). Methods FLS of knee synovial tissues from RA patients were cultured and identified in vitro in the presence or absence of ATRA, 1,25(OH)_2D_3 and DEX respectively. Synoviocyte proliferation in RA were measured by MTT colorimetrie assay and the survival fraction(SF)of FLS was evaluated. Cell cycle of FLS was observed using fluorescence-activated cell sorting(FCS)method in RA patients. Results The identified synovial cells in patients with RA were FLS(Vimentin and Fibronectin expression was positive), and hadn't been transformed or differentiated to adipocytes and osteoblasts with the three inducers. The SF of all RA-FLS interfered by ATRA, 1,25(OH)_2D_3 and DEX was much lower than that without drugs vehicle group in RA-FLS(P

Objective To investigate the proliferative characteristics of fibroblast-like synovial cells (FLS)in osteoarthritis in vitro and the mechanism of the immunosuppressive effect of total glucusides of paeony(TGP).Methods FLS of OA and non-inflamed synovium(NS)were cultured and identified in vitro in the presence or absence of TGP.After incubation,the survival fraction(SF)of FLS was evaluated by MTI' and the TNF-?,IFN-?and bFGF level in cultured FLS supernatant was measured by ELISA.The expression of FLS c-los mRNA and cell cycle of OA-FLS was observed by RT-PCR and flow eytometry respectively at the same time.Results No statistical significant differences were noted between the OA and NS FLS in pro- liferating double time.High doses of TGP suppressed FLS-SF more evidently in OA patients than in NS(P0.05).Conclusion High dose TGP can inhibit OA-FLS proliferation,modulate cy- tokine secretion and c-fos expression in OA.This suggests that TGP has immunosuppressive effect on OA syn- ovitis,probably by preventing the synovial hypertrophy in OA.
