1.Effects of Hrs on Apoptosis and Cell Proliferation in Colon Cancer Cell Lines
Journal of China Medical University 2015;(7):585-587
Objective To study the effects of Hrs on apoptosis and cell proliferation in colon cancer cell lines HCT?116 and SW?480. Methods The expression of Hrs in HCT?116 and SW?480 was knocking down by shRNA. Cell apoptosis was detected by FACS and cell proliferation was de?termined by MTT,incucyte and soft agar. Results The apoptosis was significantly increased after Hrs knocking down in both HCT?116 and SW?480,and the cell proliferation was inhibited. Conclusion Hrs is involved in the apoptosis and proliferation of colon cancer cells.

Objective:To explore the rule of CD8+CD25+FoxP3+ regulator T cells(Treg) in the pathogenesis of pre-eclampsia (PE) in peripheral blood.Methods:This study included 24 gestational-age-matched healthy pregnant women and 46 pregnant women diagnosed with mild PE (MPE,n=24) or severe PE (SPE,n=22) during the third trimester of gestation.An 3 ml sample of peripheral blood was drawn from each subject and anti-coagulated with heparin sodiurm The percentage of CD8 + CD25 + FoxP3 + Treg cells was detected by flow cytometry.The cytokines IL-6,IL-17A,IL-10,IL-1,IL-33 and TGF-β31 were detected using Luminex200.Peripheral blood mononuclear cells (PBMCs) were isolated frum healthy controls and treated with IL-33,the percentages of CD8+ CD25+ FoxP3 + Treg cell were measured by flow cytometric detection.Results:Compared to that of healthy pregnant controls [0.48(0.21-0.96)%],MPE patients [0.32(0.19-0.63)%] and SPE patients [0.13(0.02-0.41)%] had lower percentages of CD8+CD25+FoxP3+Treg cells (P<0.05).Compared to HP controls,higher levels of IL-6 and IL-17A were found in MPE and SPE patients(P<0.05) and even higher in SPE patients.The levels of IL-10,IL-1[β and IL-33 were similar in all three groups (P>0.05).Compared to HP contruls,the levels of TGF-[β1 was significantly increased in SPE and MPE patients(P<0.05),but no significant differences were found between these two groups (P > 0.05).The percentage of CD8+ CD25+ FoxP3+ Treg cells showed a negative correlation with the serum concentrations of IL-17A (r =-0.338,P =0.338),and a positive correlation with the serum concentrations of IL-33 (r =0.548,P =0.548).After PBMCs were treated with IL-33 for five days,the percentages of CD8+CD25+FoxP3+ Treg were significantly higher than those of the contruls (P<0.05).Conclusion:These findings suggested that the reduced CD8+ CD25 + FoxP3 + Treg cells may play a role in the pathogenesis of ore-eclamosia.

AIM: To analyze the causes of blindness and low vision in patients with visual disability in Yangpu District of Shanghai from 2019 to 2022.METHODS:Cross-sectional study. A total of 1 604 patients who participated in the evaluation of visual disability in Shanghai Yangpu District Kongjiang Hospital, from April 2019 to December 2022 were selected for the study. The grade of visual disability and the main causes of blindness and low vision were determined by trained doctors.RESULTS:A total of 804 patients with visual disabilities were identified, with 87.31% aged 60 and above. The causes of visual disability were high myopic retinopathy(30.47%), age-related macular degeneration(23.26%), glaucoma(17.04%), and diabetic retinopathy(11.07%). Glaucoma(36.96%)is the leading cause of blindness.CONCLUSION: The majority of patients with visual disability are aged 60 years and above. More attention should be paid to the elderly population. Comprehensive prevention, treatment and rehabilitation measures should be applied in different diseases based on classification, so as to early reduce the occurrence of visual disability.
