ObjectiveTo investigate the expression and significance of CDX2,Ki-67 in adenoma and colorectal adenocarcinoma,and the correlation between CDX2 and Ki-67.MethodsThe expression of CDX2 and Ki-67 was evaluated in the colorectal adenocarcinoma,adenoma and normal colorectal mucosa as control subjects by immunohistochemistry.ResultsThe magnitude of CDX2 were negatively correlated with the level of dysplasia in adenoma(rs=-0.38,P =0.02),and negatively correlated with differentiation,lymph node metastasis,diversion and Dukes stage of cancer in colorectal adenocarcinoma(rs=-0.49,rs=-0.37,rs =- 0.38,rs =-0.37,P =0.01).The expression and relativity of Ki-67 in the samples were contrary to the CDX2.The levels of CDX2 and Ki-67 expression had significant difference between the adenoma and adenocarcinoma,and showed negatively correlation in this two type tissues (rs=-0.69,P =0.00; rs =-0.40,P =0.00).ConclusionsCDX2 may be used as an effective marker to evaluate malignancy degree and prognosis of large bowel neoplasm patient.The levels of Ki-67 expression in colorectal adenocarcinoma are correlated with malignancy degree and clinical stage.The expression of CDX2 is negatively correlated with Ki-67.Combined detection of CDX2 and Ki-67 may be helpful for the judgment of colorectal tumor biological characters.

Objective The purpose of this study is to analyse the expression of tumor necrosis factor (TNF)-related apoptosis inducing ligand(TRAIL)and its receptors in muscle tissue from patients with idiopathic inflammatory myopathies(ⅡM)and investigate the possible role of TRAIL system in the Dathogenesis of IIM.Methods TRAIL and its receptors DR4,DR5,DCRl and DCR2 were detected in the musck biopsy tissue from 36 patients with ⅡM(13 polymyositis,23 dermatomyositis)and 9 heMthy controls bv using immunohistochemistry. Results The expression of TRAIL and its receptors was f10und in muscle tissue samples from the IIM patients and healthy controls.The expression of TRAIL,DR4 and DCR2 in the muscle tissue from the IIM patients was significantly higher than those from healthy controls(all P values< 0.05).The expression of TRAIL,DCRl and DR4 was also detected in the infiltrating lymphocytes in endomysium and in the interstitial tissue around blood vessels.Conclusion The diversity in expression of TRAIL and its receptors between patients with IIM and healthy controls suggests the hypothesis of a crucial role of TRAIL in the pathogenesis and the pathology of IIM.

As a molecular switch,Rho can be transformed between the inactive GDP-bound form and the active GTP-bound form,transfering signals to downstream effector Rho kinase (ROCK),mediating specific biological effects,and participating in various neurological diseases, such as the pathological processes of ischemic stroke,cerebral vasospasm,and axonal regeneration after spinal cord injury.The application of ROCK inhibitor in the treatment of neurological diseases has achieved satisfactory effect.Rho/ROCK is expected to become a novel therapeutic target.

Chemical Weapons Convention (CWC) and Biological Weapons Convention (BWC) are the two important international conventions in the disarmament field ,aimed to eliminate chemical and biological weapons by prohibiting the development, production, acquisition, stockpiling and use of these weapons .Recently, research and development of sci-ence and technology continue to advance rapidly .A key feature is convergence of science disciplines .This has become a new force to speed up development of science and economy .In particular , the convergence of chemistry and biology , together with the rapid advances in life sciences , has been evident in its remarkable contribution to the developments of pharmaceutics, health care, green chemistry and environmental protection .On the other hand, the convergence of chemistry and biology also has significant implications for the implementation of CWC and BWC .In this article, we summarize the new trends in the convergence of chemistry and biology and its impact on the conventions .

Mechanisms of UV-B-induced apoptotic regulation in yeast Saccharomyces cerevisiae were studied. The results showed that UV-B irradiation indeed inhibited the growth of yeast cells as well as induced extensive apoptosis during 96 h experiment period. However, survival of 96 h irradiated cells remained 10% while most control cells finally dead after re-growth under UV-B irradiation for 12 d. And by exposed to 0.01 mol/L or 0.1 mol/L H2O2 for 30 min, survival rate of 24 h irradiated cells were 3.0-fold or 3.2-fold than control, respectively. By to heat shock for 30 min or 60 min, survival rate of 24 h irradiated cells were 3.5-fold or 9.0-fold than control, respectively.

Objective The study is mainly on the effect and outcome of 131 I treatment for children and adolescents with differentiated thyroid cancer .Methods We compared the difference between rhTSH -aided ra-dioiodine treatment and L -thyroxin withdrawal .Our study collected 87 patients in a retrospective study .In order to analysis the effect,we divided into two groups.The experimental group has 46 patients,and control check has 41 patients.We compared the basic characteristics and mortality in different groups by χ2 -test,t-test and F-test based on data type .Results The thyroid stimulating hormone concentrations of experimental group patients have significant differences in the first ,the third and the sixth day after the injected of rhTSH ,the third day is the highest.The TSH concentration has significant difference between the two groups before 131I treatment(t=2.362, P=0.023).For the Tg(thyrobolulin)negative patients,Tg concentration in control check is higher than the third day after injected of rhTSH in the experiment group (1.5 ±1.2 vs.0.7 ±1.4,P=0.034).Whole body image has been done by scintigraphic after 3~8 months of 131I treatment.Thirty four(84%)patients have no radioiodine up-take in experiment group,and 40(87%)patients have no radioiodine uptake in control check ,there is no differ-ence between the two groups (χ2 =0.277,P=0.599).There is no difference between the two groups on the rea-son for retreatment(P=0.875).Conclusion The outcome of rhTSH -aided radioiodine treatment is similar to L-thyroxin withdrawal in short -term recurrences ,and rhTSH-aided radioiodine treatment with 131 I therapy for children and adolescents with DTC is a better method .
