Journal of Chongqing Medical University 1986;0(02):-
Objective:To investigate the inhibition of Eleo-Zedoary solution to human endometrial cancer cell line RL-952 in vitro and its possible mechanism.Methods:Using the MTT assay to display the sensitivity to the drug,the inhibition of Eleo-Zedoary parenteral solution to RL-952 cells in vitro was observed;and using light microscope and transmission electron microscope,the morphological alterations of the cells were observed.Results:The inhibition rate of Eleo-Zedoary parenteral solution to RL-952 indicated both dose-dependent and time-dependent anti-proliferative effect.Microscopically,the large vacuoles in the cytoplasm of the cells were found.Ultramicroscopically,many fat-like drops and obvious swelling of organelles as well as the mitochondrial cristaes in the cytoplasm of cells were observed.In addition the nucleus concentration and the chromatin fragmentation and coagulation,including the apoptotic bodies were observed.Conclusion:Eleo-Zedoary parenteral solution can inhibit the proliferation of human endometrial cancer cell line RL-952 by induing apoptosis and secondary necrosis.

3.The expression of tumor necrosis factor-related apoptosis inducing ligand and its receptors in muscle tissue of inflammatory myopathies
Chinese Journal of Internal Medicine 2008;47(5):369-373
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.
4.Rho/ROCK and Neurological Diseases
International Journal of Cerebrovascular Diseases 2008;16(3):233-236
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.
5.The expression and significance of CDX2 and Ki-67 in colorectal tumor
Journal of Chinese Physician 2012;14(2):191-194
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.
6.UV-B Irradiation Regulates Apoptosis in Yeast
Microbiology 1992;0(06):-
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.

8.Clinical implications of serum ferritin concentration in patients with impaired glucose tolerance
Journal of Medical Postgraduates 2003;0(06):-
Objective: To investigate the relationship between the serum ferritin concentration and insulin resistance in patients with impaired glucose tolerance(IGT).Methods: The serum ferritin concentration and insulin levels were measured in 40 IGT patients(20 with normal body weight and 20 with obesity),and 40 healthy controls.Blood glucose levels,HbA1C,blood adipose and urine protein concentration were obtained simultaneously.Results: In the IGT patients,the serum ferritin concentration was correlated with Hba1c but not with any other indexes,and it was significantly higher than in the normal controls.Significant differences were observed between the two groups in all the indexes but the fasting insulin level.Conclusion: The serum ferritin concentration increases in IGT patients,which implicates some association of ferritin with glucose metabolism and insulin resistance.
