Objective To study the assessment implement and its related factors in type 2 diabetic patients with mild cognitive impairment(MCI).Methods Montreal Cognitive Assessment(MoCA)(Beijing Version)was chosen as cognition assessment implement.58 type 2 diabetic patients with MCI were enrolled as the research group and 30 type 2 diabetic patients with normal cognitive function as control.HbA_(1C),blood lipid,urine microalbumin,liver and renal functions were measured in all subjects.Results Compared with control group,the blood levels of HbA_(1C)[(10.48±2.38 vs 9.28±2.19)%,P<0.05],total cholesterol[(4.87±1.18 vs 4.18±1.04)mmol/L,P<0.01],and low-density lipeprotein-cholesterol[LDL-C,(2.97±0.87 vs 2.37±0.61)mmol/L,P<0.01]increased,and high-density lipoprotein-cholesterol decreased[(1.084±0.34 vs 1.25±0.33)mmoL/L,P<0.05]in MCI group.There were significant differences in the duration of diabetes mellitus,diabetic retinopathy,body mass index,and abdominal circumference between MCI group and control group(all P<0.05).There were no significant differences in blood triglycerides,alanine aminotransferase(ALT),aspartate aminotransferase(AST),creatinine,and urine microalbumin between the two groups.MoCA scores were negatively correlated with HbA_(1C)(r=-0.396,P=0.002)and LDL-C(r=-0.275,P=0.036)in MCI group.Multiple regression analysis showed that HbA_(1C) was a significantly independent determinant for the MoCA scores.Conclusion The risk factors such as longer duration of diabetes mellitus.more diabetea mellitus complications,obesity,dyslipidemia,and inefficient control of blood glucoge all contribute to the development and aggravation of cognitive impairment.Therefore,good control of blood glucose and lipids,and reduction of complication and body weight may help to improve the cognitive function.

Tet (ten-eleven translocation) proteins belong to α-ketoglutaric acid (α-KG or 2-OG) and Fe2+ dependent dioxygenases. Tets are found to be involved in the unique mammalian DNA active demethylation process by specifically oxidizing the methyl group of 5-methylcytosine (5mC) in mammalian genome, and play critical roles in gene regulation in early embryonic development and stem cell differentiation via regulating the dynamic balance distribution of 5mC. Abnormal expression and function of Tets are closely associated with various hematological malignances, including myelodysplastic syndrome, chronic myelomonocytic leukemia, and acute lymphoblastic leukemia, as well as solid tumors. Hence, Tets and Tets-mediated DNA demethylation are novel anti-tumor drug targets. Investigation of biological function and catalytic mechanism of Tets is helpful for further understanding mechanisms of tumor incidence and development relevant to DNA demethylation pathway and can provide reference for developing new anti-tumor targeted drugs.

BACKGROUND:In recent years, tissue engineering has made great progress, and skin tissue engineering is especialy noteworthy. Artificial dermis (PELNAC) is relatively used widely, but there is a lack of relevant reports on wound repair in children. OBJECTIVE:To investigate the clinical efficacy of Pelnac? METHODS:In a retrospective study, 22 patients with the wound of severe trauma were treated with Pelnac as skin graft dressings on treatment of the wounds of severe trauma in children. ? graft, negative-pressure wound therapy and split-thickness skin graft as experimental group (Pelnac? group), and another 19 patients treated with granulation formation dressing and split-thickness skin graft as control group. We colected data including the graft livability, the required re-operative times and the epithelization time after the skin graft. During the folow-up, the skin color and texture of survival skin, subcutaneous fulness, scar hyperplasia and the joint function were also evaluated. RESULTS AND CONCLUSION: In the Pelnac ? group, the graft livability was up to 90% within 10-14 days after grafting. The secondary split-thickness skin graft was required in two cases in the Pelnac? group and in eight cases in the control group. There was a significant difference in the graft livability (P < 0.05). The average epithelization time after the skin graft was (13.86±3.09) days in the Pelnac? group, which was significant shorter than the control group, (19.10±4.62) days, after the first time operation (P< 0.05). During the 10 months folow-up, the survival skin color and skin elasticity in the Pelnac? group was significantly better than that in the control group (P< 0.05). Better subcutaneous fulness and milder scar hyperplasy in the injured sites were obtained in the Pelnac? group compared with the control gorup. Five cases had certain joint function limitation in the Pelnac? group, compared to 10 cases in the control group, with a significant difference (P < 0.05). Artificial dermis Pelnac? has a stronger anti-infectious ability and higher graft livability. Pelnac? graft combined with negative-pressure wound therapy, granulation culture and split-thickness skin graft can shorten the epithelization time, improve wound healing and aleviate harm to the joint function after the skin graft.
