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 investigate the regrlative role of the cervical sympathetic ganglia on the cochlear blood flow and auditory function in guinea pig.Methods The horseradish peroxidase(HRP) was given to spiral modiolar artery locally for retrograde tracing in guinea pig. Immunohistochemical double-labeled technique was used in this study. The cochlear blood flow and auditory brainstem response(ABR) was measured a week after anilateral superior cervical sympathectony. The animal model of superior cervical sympathectomy following noise exposure in guinea pigs was estableshed to observe the auditory threshold shift.Results Retrogradely labeled neurons with HRP were found in the ipsilateral superior cervical ganglion(SCG). Most of HRP-labeled neurons in SCG were tyrosion hydroxylase(TH) positive. The blood flow of the capillaries of the stria vascularis on the experimental side a week ago were more aplenty than that of the opposite side, but the ABR threshold did not changed before and after ablation of the superior cervical ganglion.A protective role against noise injury was observed after surgical ablation of superior cervical ganglion.Conclusion The superior cervical sympathectomy can influence the cochlear blood flow and auditory function in guinea pig.

Objective To evaluate the efficacy and safety of the InVance bulbourethral sling for stress urinary incontinence in male patients.Methods Five male patients with incontinence after prostatectomy were treated with the perineal sling(InVance).The patients aged from 62 to 76 years(mean,67 years),and the history of the incontinence ranged from 2 to 6 years(average 4 years).Four of the cases were due to TURP,and one radical prostatectomy.All the cases had been failed to respond to conservative therapies.Before the procedures,urodynamic examination showed a mean abdominal leak point pressures(ALPP)at 25.5 cm H2O(20-32.5 cm H2O).Under spinal anesthesia,a 3-to 5-cm vertical incision was made between the scrotum and the anus with the patients at the lithotomy position to expose the right and left ischiopubic branches.We put the three screws with its sutures on each bone and fixed the sling.A cough test was performed systematically and ALPP was set over 60 cm H2O.Results The operation time was 50-85 min(mean,60 min)and intraoperative blood loss was 20-50 ml(average 30 ml).The catheter was removed at day 5 and none of the patients had urination difficulty.The cases were followed up for 6 to 24 months(mean,12.6 months),during which urodynamic examination showed an ALPP at 65 cm H2O(55-70 cm H2O).Among the patients,the 4 who had received TURP were cured,and the other one undergone radical prostatectomy was improved.Conclusions InVance bulbourethral sling is suitable for mild-to-middle urinary incontinence after prostatectomy.

Objective To investigate the pathological significance of expression of IL-23 in colon tissues of patients with steroid-dependent uncreative colitis at remission.Methods Expression of IL-23 was measured by means of Western Blot and immunohistochemistry SABC in inflammation repairing areas from 15 patients with steroid-dependent ulcerative colitis at remission, 30 patients with common ulcerative colitis at remission (15 treated with SASP and 15 with prednisone) and 10 normal colon tissues.The results were analyzed by SPSS 16.0.Results Compared with normal control, expression of IL-23 in patients of SASP maintenance therapy and prednisone with common ulcerative colitis were slightly increased ( P > 0.05), which was significantly lower that of steroid-dependent specimens ( P < 0.01).Conclusion Over-expression of IL-23 may plas a key role in the pathogenesis of steroid-dependent ulcerative colitis.

Objective To investigate the effects of propofol on the release of noradrenaline ( NE) from the locus coeruleus in the brain of rabbits trying to elucidate the central mechanism of the cardiovascular inhibition induced by propofol.Methods Nine healthy male New Zealand rabbits weighing 2.0-2.5 kg were used in this study. A trocar (0.8 mm in diameter) was inserted into locus coeruleus using the stereotactic technique and fixed. Four days later push-pull perfusion of the brain was performed. 37℃ artificial cerebrospinal fluid (aCSF) was infused through the trocar at 0.1 ml?min-1 . A loading dose of propofol 2 mg?kg-1 was given i.v. followed by continuous infusion at 150 ?g?kg-1?min-1 for 30 min. The experiment was concluded at 20 min after propofol infusion. The perfusate having passed through the locus coeruleus was collected before and every 10 min during and after infusion. The NE concentration of the perfusate was measured by high performance liquid chromatography. Results The NE concentration of the perfusate from locus coeruleus significantly decreased after the loading dose and during the infusion of propofol and reached its bottom level at 10 min after loading dose. The maximal decrease was 75.5% [from (15.9 ? 3.2) pg??l-1 to (3.9?0.5) pg ? ?l-1]. Conclusion Intravenous propofol decreases the NE concentration in locus coeruleus. The cardiovascular inhibition induced by propofol may partly be explained by this central mechanism.

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.
