Objective To investigate the application value of the Mini-Nutritional Assessment (MNA) in assessing the nutritional status in middle-aged women with diabetes.Methods Using the normal range of traditional nutritional index as the reference standard,two hundred and forty middle-aged women with diabetes were recruited and their nutritional status were assessed by MNA and laboratory test (including PAB,Fib,TLC,CHOL),respectively.Finally,the results were analyzed and compared.Results The correlation coefficient of MNA value and BMI、PAB,Hb,TLC,CHOL were 0.571,0.614,0.781,0.568,0.218.MNA had good correlations with several traditional laboratory indicators regarding with nutritional status,with signifi-cant difference.In this study,the results of investigation by MNA showed that:the rates of malnutrition,potential malnutrition,and normal nutritional were 30％(72 cases),65％(156 cases),and 5％(12 cases),respectively.The sensitivity and specificity of MNA were 96.1％ and 98.2％ respectively.Laboratory testing resuits:malnutrition and normal nutrition were 31％ (74 cases) and 4％ (10 cases).Kappa test(Kappa=0.922):the results of MNA and laboratory testing had strong consistency.Conclusions MNA is feasible in assessing nutritional status in the domestic middle-aged women with diabetes.

AlM: To observe the influence of phacoemulsification combined with intraocular lens implantation on retinal thickness changes of macular center fovea using optical coherence tomography ( OCT) in cataract patients.METHODS: Surgical eyes of 60 cases with cataract were as surgery group, the contralateral eye were as controls group. There was no complication before and during the surgery. Macular thickness was examined by OCT preoperatively and 1wk, 1, 3, and 6mo after surgery. The retinal thickness changes of macular center fovea were compared after surgery. The SPSS 17. 0 software was used for statistical analysis. The paired t-test and variance analysis were used in two groups before and after surgery for relevant statistical data analysis (α=0. 05).RESULTS: ln surgery group, the retinal thickness changes of macular center fovea at 1wk, 1, 3mo after treatment had significant differences compared with preoperation (P<0. 05). The retinal thickness changes of macular center fovea at 6mo after treatment had no statistical significance compared with preoperation ( P>0. 05). The retinal thickness changes of macular center fovea was significantly higher than other groups at 1mo after treatment (P<0. 05). The center fovea appeared to be abnormally thickened in 12 eyes, including 10 eyes of single fovea thickening and 2 eyes of cystoid macular edema in 2~4wk following surgery. Eleven eyes of them were resolved till 6mo postoperatively. ln control group, preoperation or after operation for 1wk, 1, 3, and 6mo respectively, P values were without statistical differences ( P > 0. 05 ). There were no statistical significant differences on retinal thickness of macular center fovea between two groups before and 6mo after surgery ( P>0. 05), while there were significant differences at 1wk, 1 and 3mo after surgery (P<0. 05) CONCLUSlON: The retinal thickness changes of macular center fovea increases significantly after phacoemulsification combined with intraocular lens implantation. ln a few of cases appear macular edema, but the majority of patients can be restored, prognosis is good.

Objective To study whether the protective effects of fenofibrate on insulin resistance in mice of nonal-coholic fatty liver disease(NAFLD) are related to endoplasmic reticulum stress (ERS). Methods Male C57BL/6 mice were fed with high-calorie and high-cholesterol diet ( HCD) to induce a model of NAFLD, then one of those two groups from HCD was treated with fenofibrate 40 mg/( kg · d ) for 2 weeks ( HCF ) . Glucose tolerance test (GTT) and insulin tolerance test (ITT) were used to analyze the improvement on insulin resistance. The serum levels of triglyceride ( TG) , total cholesterol ( TC) , high density lipoprotein-cholesterol ( HDL-C) , low density lip-oprotein-cholesterol ( LDL-C) , alanine aminotransferase ( ALT) and aspartic transaminase ( AST) were detected. The pathological changes of livers were detected with HE and Oil Red O staining, the mRNA and protein expression of peroxisome proliferator-activated receptorα( PPARα) , glucose regulated protein 78 ( GRP78 ) and transcription factors GADD153 ( CHOP) were detected with real-time quantification PCR and Western blot analysis respectively. Results Compared with the SCD mice, the HCD mice showed significant insulin resistance, higher serum levels of TG, TC and LDL-C (P<0. 01, P<0. 05), lower serum level of HDL-C (P<0. 01), micro-and macrovesicular steatosis, ballooned hepatocytes and infiltration of inflammatory cells were observed in the liver, the expressions of PPARα and GRP78 at mRNA and protein levels were decreased (P<0. 05), however, the expressions of CHOP at mRNA and protein levels were increased ( P<0 . 05 ) . Fenofibrate intervention significantly improved insulin resist-ance and decreased the serum level of TG ( P<0. 05 ) . Fenofibrate also alleviated hepatic steatosis and inflammato-ry infiltration, and increased the mRNA and protein expressions of PPARα and GRP78, decreased the mRNA and protein expression of CHOP ( P<0 . 05 ) . Conclusion Fenofibrate significantly improves insulin resistance and de-creases the serum level of TG in NAFLD mice, which may be related to activating PPARα and relieving ERS.
