Objective To investigate the effect of 12-lipoxygenase(12-LO) on the p27Kip1 expression in diabetic glomeruli. Methods Mesangial cells were exposed to 12-LO product 12 (S)-HETE (10-7 mmol/L) with or without p38 MAPK (p38) inhibitor (SB203580, 1 μmol/L) for 24 hours. Rats fed with high fat diet received low dose streptozotoein (ST-Z, 35 mg/kg, IP injection) to develop type 2 diabetes and were divided into 2 groups: low dose STZ, low dose STZ+12-LO inhibitor cinnamyl-3,4-dihydroxy-α-cynanocinnamate (CDC, 8 mg/kg) treatment. Rats fed with regular chow were divided into two groups: controls, CDC treatment. The rats received injection of CDC or vehicle subcutaneously in the hind leg. CDC or vehicle injection was performed three times weekly on alternate days. All the rats were sacrificed after 4 weeks, Wild type and 12-LO knockout C57BL/6 mice were divided into 4 groups: wild type control, 12-LO knockout, STZ-induced wild type type 1 diabetes and STZ-induced 12-LO knockout type 1 diabetes. All the mice were sacrificed after 16 weeks. Urine, blood, kidney cortical tissue and isolated glomeruli by sieving method were collected at the end of study respectively. Western blot and immunohistochemistry for target protein were performed respectively. Results Inhibition of p38 activation could significantly reduce p27Kip1 expression induced by 12 (S)-HETE in mesangial cells (P<0.01). Increased glomerular volume, microalbuminuria, elevated glomeluli p38 activation, p27Kip1 expresssion in type 2 diabetic glomeruli was decreased after CDC treatment (P<0.01). Compared with wild type diabetic mice, glomerular p38 activation, p27Kip1 exprcsssion and extracellular matrix accumulation in the 12-LO knockout diabetic mice were significantly decreased (P <0.01, respectively). Conclusions 12-LO induces p27kipl expression via p38 pathway in diabetic glomeruli.

Objective:To investigate the effect of 12(S)-HETE on the p27~(kip1) expression in mesangial cells and glomeruli.Methods:Mesangial cells were exposed to 12(S)-HETE.12(S)-HETE was infused to rats by osmotic mini-pump.Total protein content measurement for cell hypertrophy,RT-PCR for mRNA expression and Western blot for protein expression were performed respectively.Results:12(S)-HETE stimulation induced mesangial cell hypertrophy and p27~(kip1) protein expression,but not p27~(kip1) mRNA expression.Furthermore,p27~(kip1) mRNA and protein expression in the glomeruli were significantly increased by 12(S)-HETE stimulation using osmotic mini-pump.Conclusion:12(S)-HETE plays an important role in the pathogenesis of glomerular cell hypertrophy and senescence through upregulation of p27~(kip1) expression.

Objective To construct the diabetic home care platform and to explore its effects in follow-up man agement of patients with gestational diabetes mellitus.Methods The diabetic home care platform contained clientsides for both nurses and patients,who could use the platform via identification and binding technology.Totally 200 patients with gestational diabetes mellitus in outpatient department from November 2015 to December 2016 were recruited using convenience sampling.Patients were divided into the experimental group and the control group with 100 cases in each group based on the voluntary principle.Both groups received routine follow-up management,and the experimental group also used diabetic home care platform management.Results There were no differences in gestational weeks,mode of delivery,postpartum hemorrhage,other complications,fetal intrauterine distress,neonatal hypoglycemia,and deformity between two groups(P＞0.05).Rate of macrosomia in the experimental group was lower than that in the control group(P＜0.05),and rate of breastfeeding was higher than the control group(P＜0.05).The total score of Diabetes Self-Care Activeties-6 and scores of each dimension in the experiential group were higher than those in the control group 8 weeks after intervention(P＜0.001);the total score of Problem Areas in Diabetes Scale and scores of each dimension in the experimental group were lower than those in the control group(P＜0.05).Conclusion Application of diabetic home care platform is helpful for fetal weight control,and can improve rate of breastfeeding,promote women's self-management behavior and emotional disorders.

Objective To analyze theoretical frameworks, definitions, terminology and measurements of disability using International Classification of Functioning, Disability and Health (ICF), and United Nations Convention on the Rights of Persons with Disabilities (CRPD), to provide a scientific basis for developing definition, classification and measurements to meet international standards.Methods Content analysis had been conducted for the definitions and measurements of disability issued by international organizations using the ICF terminology and code and the definitions of disability and people with disability by CRPD.Results The core concepts and content had been reviewed using the ICF terminology and code, and the definitions of disability and people with disability by CRPD. The contents of definitions of disability proposed by international organizations cover all components of ICF. The contents of standardized disability measurements issued by United Nations or World Health Organization cover all components of ICF and map to CRPD definitions of disability and people with disability as the framework, classification, terminology and coding system had been adopted for the development.Conclusion The definition and measurements had been developed using ICF and CRPD framework, terminology, and coding system of disability. The framework and standard of disability had been constructed. The standard of disability data will implement in the fields of health, rehabilitation, education, employment, community and social services for people with disability to promote data exchange across sectors.
