Objective:To investigate the relationship between gene polymorphisms of disease-relevant multiple cytokines including TNF-α,IL-6,IL-10,TGF-β1,IFN-γand acute graft versus host disease(aGVHD) in allogeneic hematopoietic stem cell trans-plantation ( allo-HSCT ) . Methods:32 cases of recipients received allo-HSCT and 36 cases of normal groups in January 2014 to December 2015 were selected as objects of study. We detected genotypes on specific SNP of target genes by polymerase chain reation ( PCR) combined with gene sequencing and observed the occurrence of aGVHD in postoperative recipients. The influence of cytokine gene polymorphisms on prognosis of allo-HSCT patients was analyzed,and the potential relationship between specific SNP mutation of the disease-relevant cytokine genes and severity of aGVHD was discussed. Results:Distribution of cytokines gene polymorphism including TNF-α-308(G/A),IL-6-174(G/C),IL-10-1082(A/G),TGF-β1+915(G/C),IFN-γ(T/A) had no significant differences with incidence of severe aGVHD(P>0. 05). However,the occurrence of severe aGVHD in allo-HSCT recipients with C/T genotype was significantly higher than C/C and T/T in SNP of TGF-β1+869(P<0. 01). Conclusion:Gene polymorphism of TGF-β1+869(C/T) in allo-HSCT patients was closely related to the occurrence of severe aGVHD. The research show allo-HSCT patients with C/T genotype occurred severe aGVHD more frequently, which is an important potential risk factor to induce the incidence of severe aGVHD. Therefore,detecting gene polymorphism of TGF-β1+869 ( C/T ) in allo-HSCT recipients and developing the appropriate therapeutic regimen may be helpful to reduce the incidence of aGVHD.

To investigate the suitable site environment for Atractylodes lancea, field trials in different niches was carried out, and the seedling growth, biomass and volatile oil components in different microhabitas was studied. The study found that the survival rate, plant height, volatile oil content of those which growing under the bamboo were significantly higher than those exposed in the open field. The survival rate understory was (76 ± 15.1) %, plant height understory was (77 ± 14. 8) cm and the summation of the four kinds of volatile oil content understory reached up to 4.09%; The same evaluation values of these indicators of the four faces in the open field respectively: survival rate is 30%, plant height was (77 ± 14.8) cm and the summation of the four kinds of volatile oil content was 2.24%. But, the yield of the understory (41 ± 22.3) g was significantly lower than those four faces in the open field (104.5 g) on the contrary. For the four open field towards, the yield of the east facing, which organic matter and other nutritional conditions were better than others, was significantly higher than those in the other facings. A. lancea was found to be an anti-poor and shading-like or growing in east facing slope herb through the correlation analysis of light, temperature, soil and leaf nutrients with seedling growth, biomass and volatile oil components. It also reminds us that the understory herb with high survival rate, low incidence, low management costs, and high medicinal ingredients, although it's production is not so high, but it can be improved by increased organic fertilizer. So the ecological planting patterns which can intercropping herbs with the forest was proposed.

OBJECTIVETo find the development rules of microbial community in rhizoma sphere of the cultivated Atractylodes lancea.
METHODTotal bacteria, fungi and actinomyces were counted by CFU x g(-1) though dilution plate method. And genomic DNA of microbes were extracted and amplified by primers of E. coli's 27f and 1492r to get the 16S rDNA, then the restriction endonuclease Hinf was used to digest the 16S rDNA.
RESULTTotal bacteria, fungi and actinomyces in 2-year old soil were lower than in 1-year old soil, they decreased 46. 14%, 49. 25%, 31.88% respectively and made the ratio of themselves changed. At the same time, all the 8 soil samples got fine 16S rDNA bands, which were about 1500 bp. And the main bands of most of the samples were found at 1000 bp, but the weak bands of each were different although most bands in the same year samples were more similar than in different year ones.
CONCLUSIONIt is indicated that the change of soil microbial community may has some relation to the continous cropping barrier of A. lancea.

Objective To investigate the effects of iodine excess on mitochondrial superoxide production and mitoehondrial membrane potential(△ψ)changes in Fisher rat thyroid cell line(FRTL)cells.Methods FRTL cells were treated with 10-4mol/L potassium iodine(KI),10 U/L thyrotropin(TSH),10-4 mol/L KI+10 U/L TSH respectively for 24 h.Effects on cell proliferation were assayed by methyl thiazolyl tetrazolium(MTT)colorimetric method.Changes of mitochondrial superoxide production and △ψ were measured by live cell imaging and spectrofluorometer using MitoSOX and rhodamine 123(rh123)respectively.Results Absorbance(A)in the KI group (0.794±0.144)showed a significant decline compared to the control group(1.000 ±0.183,P<0.05),whereas a significant elevation was observed in the TSH group(1.215±0.156,P<0.05).No significant differences was found between the KI+TSH group(1.025±0.254)and the control group(P>0.05),but the former was marked higher than the KI group(P<0.05).Compared to the control group(9.74±3.24).MitoSOX mean fluorescence intensity (MFI)in the KI and KI+TSH groups(18.16±6.57,13.33±2.92)were significantly increased(all P<0.05),which was a significant decline in the TSH group(6.64±2.15,P<0.05).MitoSOX MFI in the KI+TSH group was lower than the KI group(P<0.05).Rh123 MFI in the KI and KI+TSH groups(210 593±31 328,295 525±34 243)showed significant decline than the control group(407 824±37 198,all P<0.05).Compared with the KI group.the KI+TSH group pronouncedly attenuated the reduction of Rh 123 MFI(P<0.05).No significant differences of Rh 123 MFI were found between the TSH group(411 187 ± 72 852) and the control group(P > 0.05). Conclusion Iodine excess (10-4 mol/L KI) may lead to peroxide damage on the mitochondria of FRTL cells, and cell proliferation is inhibited. Combining treatment with 10 U/L TSH may attenuate mitochondrial peroxide damage and inhibition of cell proliferation caused by iodine excess.
