Objective: To study the affection of Diallyl trisulfide on cultured human colon carcinoma cell line HT-29 and its mechanism. Methods: The viability of cells after various treatments were determined using the method of MTT. Flow cytometry were used to analyze the change of cell cycle and Bcl-2, Bax levels. Results: The proliferation of human colon carcinoma HT-29 cells were inhibited by Diallyl trisulfide. The inhibition was associated with dose and time dependence. Flow cytometry results showed that: 1) When cells were treated with Diallyl trisulfide at the concentration of 10 ?g/mL for 12 h and 24 h, the percentage of G0/G1 phase cells was decreased and that of G2/M phase cells was significantly increased compared with those in the control group.2) Diallyl trisulfide down regulated Bcl expression, while up-regulated bax expression. Conclusions: It was suggested that Diallyl trisulfide inhibited HT29 cell proliferation. And these were associated with arrest of cell cycles and down regulation of Bcl2/Bax ratio.

To investigate the influence factors and effects of metal or dissolving microneedles on the formation and healing of skin microchannels, the pencil-shaped or conical stainless steel microneedles with different lengths, tip to tip space and base area, and the pencil-shaped dissolving microneedles with different tip to tip space were used. The microneedles were applied to the skin of epilatory mice and rats, and the effects of various microneedle parameters, application parameters, and animals on the microchannels were explored by the transepidermal water loss (TEWL) and methylene blue staining. Visually observe the skin local irritation caused by the microneedles. The animal experiments were approved by the Animal Experiments Welfare and Ethical Committee of Zhejiang University of Technology. The application time of the microneedle should be maintained at 30 s or more. When the insertion forces were 2, 4, 8 N, and the TEWL initial values of the formed microchannels were 12.9, 33.0, 40.4 g·m^-2·h^-1, respectively. When the length of metal microneedle were 400, 600, 800 μm, and the TEWL initial values of the formed microchannels were 37.1, 40.4, 49.5 g·m^-2·h^-1, respectively. When the tip to tip space of metal microneedle were 400, 600, 800 μm, and the TEWL initial values of the formed microchannels were 33.2, 40.4, 55.8 g·m^-2·h^-1, respectively. When the base area of metal microneedle were 0.16, 0.35, 0.62 cm², and the TEWL initial values of the formed microchannels were 35.1, 40.4, 67.1 g·m^-2·h^-1, respectively. The effects of conical and pencil-shaped microneedles are similar. When the tip to tip space of pencil shaped dissolving microneedle were 400, 600, 800 μm, and the TEWL initial values of the formed microchannels were 49.8, 60.5, 70.5 g·m^-2·h^-1, respectively. The TEWL baseline values of animal skins of different genders and series are different, but the tendency of microchannels formation and closure is similar. Visual inspection revealed that the slight erythema caused by the microneedles subsided within 24 h. Microneedles of different parameters have different effects on microchannels. The microchannels closed within 24 or 48 h, and the skin local irritation caused by microneedle was mild.

AIM:To study the KIF21A gene mutation in a Han family with concomitant exotropia. ·METHODS: The genomic DNA of five family members was extracted from peripheral blood leukocytes and amplified with PCR. The PCR products were purified for DNA sequencing. DNA sequences were aligned with the human KIF21A gene sequences registered in GenBank. · RESULTS: Mutation analysis of all exons of the pedigree's KIF21A gene reveals no gene mutation in any of the families. ·CONCLUSION: Our study demonstrates that the KIF21A gene maybe is not virulence gene in this pedigree.

Objective:To investigate the expressions of peripheral lymph node addressin(PNAd)andGlcNAc-6-sulfotransferase(GlcNAc6ST)in endometrium and their impacts on implantation.Methods:PNAd expression in endometrium was examined by immunohistochemistry and Western Blot from 75women(12 from healthy women,in proliferative phase;63 from sterile women,of whom,27 were inearly-secretory and 36 in mid-secretory phase).GlcNAc6ST mRNA was examined by real-time PCR in41 sterile women.The 63 sterile women had underwent ⅣF-ET and were consequently divided into clini-cal pregnant(29 cases)and nonpregnant(34 cases)groups.Results:(1)PNAd localized to the mem-brane and cytoplasm of luminal and glandular epithelia.Staining was patchy and much less intense duringthe proliferative phase than during the secretory phase.In Western Blot of PNAd,four bands appeared,which were Sgp200,CD34,MAdCAM-1,GlyCAM-1 respectively,and each was positively correlatedwith the others significantly.The former three molecular levels were significantly higher during the secre-tory phase as compared with the proliferative phase.Message RNA of GlcNAe6ST was positive in all ca-ses and showed no correlation with any component of PNAd.(2)The expressions of CD34 and GlyCAM-1,but not Sgp200 and MAdCAM-1,were significantly higher in pregnant women than in nonpregnantones.However,the GlcNAc6ST mRNA level did not differ between groups.(3)No significant differ-ence was found in female age,methods of fertilization,thickness of endometrium on day hCG,cumulativeembryo score(CES)and mean score of transferred embryo(MSTE)between the groups.Conclusion:PNAd expression in the human endometrium fluctuates with the menstrual cycle.Elevated CD34 and Gly-CAM-1 during the secretory phase might be stimulative factors for embryo implantation.Defect in PNAdexpression may account for a portion of unexplained infertility.

Objective To investigate the personality traits, anxiety and depression in patients with leukemia. Methods A cross-sectional survey was performed in 120 patients with leukemia and 118 age and gender-matched controls. Personality was assessed using the Type A Behavior Pattern Questionnaire (TABPQ). Emotion was ascertained using the self-rating anxiety scale (SAS) and self-rating depression scale (SDS). The relationship between personality type A and anxiety and depression was evaluated by Pearson correlation analysis. Results The prevalence of personality type A was significantly higher in patients with leukemia than healthy controls [71.67 % (86/120) vs. 30.51 % (36/118), P< 0.01]. Patients with leukemia also had higher prevalence of anxiety and depression compared with healthy controls [36.67%(44/120) vs. 9.32%(11/118), P< 0.01; 29.17 % (35/120) vs. 5.93 % (7/118), P< 0.01]. Pearson correlation analysis showed that time-hurry (TH) and competition-hostility (CH) of personality type A correlated positively with anxiety (r=0.292, r= 0.277, respectively; both P< 0.05). Conclusion TH and CH of personality type A are associated with anxiety in leukemia patients.
