Objective To observe the expression of small ubiquitin?related modifiers(SUMO)protein in normal cultured human lens epithelial cells(SRA01/04)and discuss regulation effects of SUMO protein on oxidative stress induced by high glucose. Methods The expression and local?ization of SUMO 1,2/3,4 was detected in normal cultured SRA01/04 cells through immunocytochemistry. The mRNA expression levels of SUMO 1?4 were examined by RT?PCR after the SRA01/04 cells treated with high glucose media at different concentrations and time points. Samples were grouped by medium concentrations(glucoses 5.5 mmol/L,12.5 mmol/L,25 mmol/L,50 mmol/L respectively for 24 h)and by treatment time(0 h, 6 h,12 h and 24 h respectively). After highly efficient transfection of GFP?SUMO2 into SRA01/04 cells,the survival and apoptotic rates of transfect?ed and un?transfected cells treated with high glucose was detected by CCK8 method and AV/PI double staining flow cytometry. Results The immu?nocytochemistry results showed that SUMO1,2/3,4 proteins were mainly located in the nucleus of SRA01/04 cells and part of SUMO2/3 was in the cytoplasm. RT?PCR results showed that compared with the low?glucose group,the mRNA expression of SUMO1?4 was increased along the increas?ing glucose concentration in the high?glucose group(P<0.05). Compared with 0 h,the mRNA expression of SUMO1?4 was enhanced at 6 h,12 h and 24 h(P<0.05)in the high?glucose group treated at 50 mmol/L concentration. Compared with the un?transfected cells,the survival rate was in?creased and the apoptotic rate was decreased in GFP?SUMO2 transfected cells in oxidative stress induced by high glucose(P<0.05). Conclusion SUMO protein was positively expressed in SRA01/04 cells and the expression of SUMO mRNA was affected by oxidative stress induced by high glu?cose.

OBJECTIVE:To compare the effects of repeated subcutaneous insulin administration vs. insulin pump continuous subcutaneous administration on related indexes of advanced age patients with gestational diabetes mellitus(GDM). METHODS:Inretrospective study,120 advanced age patients with GDM were randomly divided into group A(60 cases)and group B(60 cases). Group A was given Insulin aspart injection with initial dose of 0.5 U/(kg·d)subcutaneously before meal,adjusted according to fast-ing blood glucose(FPG)and postprandial 2 h blood glucose(2 hPG),and then given Isophane protamine biosynthetic human insu-lin injection with initial dose of 0.5 U/(kg·d)subcutaneously at bedtime,adjusted according to FPG and 2 hPG. Group B was giv-en Insulin aspart injection with initial dose of 0.5 U/(kg·d)added into insulin pump using 40% of total daily insulin as basic pump,increasing to 60% of total daily insulin if blood glucose control was poor,adjusted according to FPG and 2 hPG. Treatment course of 2 groups lasted for 4 weeks. The time of blood glucose reaching target,the amount of insulin were observed in 2 groups, and the levels of FPG,2 hPG,HbA1c,Hcy and Cys-C before and after treatment,the occurrence of patients and neonates compli-cations. RESULTS:The time of blood glucose reaching standard in group B was significantly shorter than group A;the amount of insulin,the incidence of hypoglycemia,premature birth,excessive amniotic fluid and gestational hypertension in group B were sig-nificantly lower than group A,with statistical significance(P<0.05). The incidence of neonatal respiratory distress syndrome in group B was significantly lower than group A,with statistical significance(P<0.05);but there was no statistical significance in the incidence of giant baby and malformation between 2 groups(P>0.05). After treatment,the levels of FPG,2 hPG,HbA1c,Hcy and Cys-C in 2 groups were significantly lower than before treatment,and the group B was significantly lower than the group A, with statistical significance(P<0.05). CONCLUSIONS:The insulin pump continuous subcutaneous administration is significantly better than repeated subcutaneous insulin administration in respects of controlling glucose level,reducing the amount of insulin,the levels of Cys-C and Hcy,maternal and neonatal complications.

With the aging of the population, the incidence of degenerative lumbar scoliosis has increased year by year. Long-segment orthopedic fixation surgery is an important method for the treatment of severe degenerative lumbar scoliosis. Currently, the evaluation of postoperative results is mainly based on the degree of relief of postoperative clinical symptoms, as well as the improvement of imaging deformity and balance. The studies show that although surgery has high difficulty and risk, most patients can benefit from surgery. Besides, it is reported that long-segment fixation can alleviate the symptoms of pain and improve the quality of life. However, it also decreases the local activity of the lumbar spine, leading to stiffness of lumbar, which may affect the activities of daily living (ADL) partly. Lumbar Stiffness Disability Index (LSDI) is a scale for evaluating the impact of lumbar spine stiffness on ADL. The scale has certain limitations and needs to be applied to Chinese people on the basis of optimization. In this paper, the researches of lumbar spine function evaluation after degenerative lumbar scoliosis and long segmental orthopedic fixation and the clinical use of LSDI are briefly reviewed.
