Objective To evaluate the efficacy of different duration of low-carbohydrate diet (LCD) intervention on glycosylated hemoglobin (HbA1c) in type 2 diabetes mellitus (T2DM) patients. Methods Randomized controlled trials (RCTs) of LCD intervention in T2DM patients were collected in the databases such as MEDLINE, PubMed, OVID, China National Knowledge Infrastructure, China Scientific Journal Database by VIP, Wanfang database, et al.Data were analyzed by RevMan 5.3 version. Results Eight RCTs were included. The results of Meta-analysis indicated that the effects of lowering HbA1c by LCD intervention for three (Z=2.28, P<0.05) and six months (Z=14.99, P<0.01) were better than other diabetes diets, but there was no significant statistical difference between one (Z=0.65, P=0.51) and two years (Z=1.62, P=0.10). Conclusions Hypoglycemic effect of short-term LCD was better than other diabetes diets, but long-term effect was similar between them. LCD was a therapeutic diet suitable for T2DM patients.

Objective To study the effect of UHRF1 expression inhibition by RNA interference on the radiosensitivity of esophageal cancer cell line TE-1 and its mechanism.Methods Short hairpin RNA (shRNA) targeting UHRF1 gene was introduced into TE-1 cells by lentivector-mediated transfer.The cells were divided into three groups:non-transfected group,negative control (NC)-shRNA-transfected group,and UHRF1-shRNA-transfected group.The mRNA and protein expression levels of UHRF1 in TE-1 cells were measured by RT-PCR and Western blot before and after transfection.After transfection and X-ray radiation,the radiosensitivity of TE-1 cells was evaluated by colony formation assay; the cell cycle and cell apoptosis were determined by flow cytometry; the γ-H2AX (as a marker of DNA damage) level was measured by Western blot.Results After transfection with UHRF1-shRNA,the mRNA and protein expression levels of UHRF1 were significantly decreased in TE-1 cells,as compared with those in the NC-shRNA-transfected group and non-transfected group (0.11 vs 0.96 and 0.98,F =124.21,P =0.000;0.10 vs 0.89 and 0.94,F =125.25,P =0.000).The UHRF1-shRNA-transfected group had sensitization enhancement ratios of 1.53 (D0 ratio) and 1.95 (Dq ratio).X-ray radiation could cause G2/M arrest and increase apoptotic rate and γ-H2AX expression in TE-1 cells.Compared with the two control groups,the UHRF1-shRNA-transfected group showed significantly less G2/M arrest (F =500.15,P =0.000),a significantly higher apoptotic rate (F =100.10,P =0.000),and significantly higher residual γ-H2AX expression (F =61.00,P =0.000) at 24 hours after X-ray radiation.Conclusions RNA interference can effectively inhibit the UHRF1 expression and enhance the radiosensitivity of TE-1 cells.The mechanism may be related to cell cycle regulation,cell apoptosis,and DNA damage repair.
