Objective To observe the effect of iodine deficiency and hypothyroidism on the protein expressions of CREB in the entorhinal cortex of pups.Methods Twenty-eight female Wistar clean rats after pregnancy were randomly divided into control group,hypothyroid 1,2 group and iodine deficient group(7 in each group).From GD6 till PN28,iodine-deficient group was administered with iodine-deficient diet [iodine content:(14.11 ?1.96) ng/g] and tap water;hypothyroid 1 and 2 group were administered with 5 mg/L and 15 mg/L PTU in the drinking water and fed with normal diet [iodine content:(470.50?46.52) ng/g].Control group received tap water and normal diet during the experiment.Five pups from each group were sacrificed and intracardiac perfused at PN7,PN14,PN21,PN28 and PN42.Brains were removed,fixed and sectioned coronally.All sections were observed and were analyzed for the protein expression of CREB by immunohistochemistry in the entorhinal cortex.Results At PN7,there was no significant difference in the expression of Ng in all four groups.At PN14 and PN21,the expression of CREB in the entorhinal cortex in hypothyroid 1,2 group and iodine deficient group were significantly lower than those of controls(P

AIM: To investigate the changes of first order kernel ( FOK ) and second order kernel ( SOK ) of multifocal electroretinogram( mf-ERG) in detecting the early retinal abnormalities in sub-clinical stage of diabetic retinopathy. ·METHODS: Totally 32 patients ( 58 eyes ) with type 2 diabetes mellitus ( DM ) without apparent diabetic retinopathy( DR) were detected by mf-ERG, from June 2014 to May 2015. Thirty cases ( 60 eyes ) of normal control group had also been taken to compare the difference of the amplitude and latency between the two groups. ·RESULTS: Compared with the control group: there was no statistical difference in the FOK b-wave latency of the diabetic group, and the FOK b-wave amplitude was significantly decreased (t=3. 099, P=0. 012). The SOK b-wave latency in diabetes group was statistically delayed (t=2. 643, P=0. 025), and the SOK b-wave amplitude statistically decreased (t=4. 833, P<0. 01). There was no statistically difference in the a-wave latency and amplitude of FOK and SOK. The b-wave amplitude of FOK and SOK was negatively correlated with the course of the disease. However, the b-wave amplitude was not statistically correlated with the duration of diabetes mellitus. ·CONCLUSION: The function of the post-polar outer and inner retina detected by FOK and SOK had been damage even before retinopathy. The anomaly is mainly reflected by the decreasing amplitude of b-wave.

Objective To observe the climical significance of controlling plasma glycemia in pregnant women with gestational diabetes mellitus( GDM ) for improving the pregnant result and reducing the complications of maternal and fetus.Methods 120 pregnant women with GDM were dioided into two groups according to the information of plasma glycemia control,including 86 cases with well-controlled plasma glycemia ( A group) and 34 cases with poorcontrolled plasma glycemia( B group).50 cases normal pregnancy were selected as control group.The differences in complications of maternal and fetus were observed.Results Only the morbidity of PIH of A group was higher than that in normal pregnant women( x2 =5.920,P ＜ 0.05 ),while the morbidity of PIH,polyhydramnios,fetal macrosomia,premature labor,and newborn asphyxia in B group were higher than those in A group( all P ＜ 0.05 ).Conclusion Paying more attention on screening GDM in pregnant women,early diagnosis and control of blood glucose was essential for reducing the incidence of maternal and fetal complications.

Objective To explore the causes of readmission after prostatectomy for BPH and to discuss the treatment approaches. Methods A total of 106 cases who were eligible for the study were reviewed.47 cases had residual and recurrent adenoma;of these cases,42 underwent TURP and 5 open prostatectomy again.32 cases developed urethral stricture;of these cases 27 underwent transurethral cold knife incision plus electric resection of scar and 3 urethral orifice reconstruction and 2 suprapubic cystostomy.11 cases who had experienced bleeding after TURP underwent transurethral bladder washing and coagulating.7 cases had neuropathic bladder dysfunction;of these cases 2 underwent transurethral bladder neck circle muscle resection,3 intermittent self-catheterization and 2 suprapubic cystostomy.6 cases had prostatic cancer;of these cases 1 underwent radical prostatectomy,3 palliative TURP plus orchiectomy and 2 orchiectomy.2 cases had incontinence after TURP;of the 2 cases 1 used external collecting device and 1 was transfered to other hospital for surgery.1 case had abdominal incision hernia and then underwent hernia repair. Results Among 106 cases, 97 cases underwent operations and of them 84 (86.6%) cases achieved successful results.The follow-up time was 6 months to 15 years with a mean of 5 years and 8 months.9 cases with urethral stricture required regular urethral dilation after surgery.4 cases who had had unsuccessful surgery underwent suprapubic cystostomy.Other 9 cases did not undergo operations due to poor health and other reasons. Conclusions Correct preoperative diagnosis, rational surgical type and adequate intraoperative and postoperative management are key to preventing readmission. Transurethral surgery is most favorable treatment choice for readmitted patients after prostatectomy for BPH.

Objective To observe the effect of Vitamin E on advanced glycosylation end-products(AGEs) and their receptors in renal tissue of diabetic rats.Methods Rat diabetic nephropathy was induced by intraperitoneal injection of STZ.Rats were allocated to normal control group(NC group),diabetes mellitus group(DM group),and Vitamin E group(VE group).All rats were treated with corresponding drugs for 8 weeks.During and after the treatment,the general state,blood glucose level(BGL),blood urea nitrogen(BUN),serum creatinine(Scr),urinary albumin excretion rate(UAER),glycosylated hemoglobin(HbA1C),clearance rate of creatinine(Ccr) and kidney weight/body weight ratio were determined in different groups.The fluorescence microscope was used to observe advanced glycosylation end-products fluorescence intensity in iced slices.The expression of RAGE in rats' renal tissue slices was measured by immunohistochemistry.Results ① Compared with those in NC group,GLU,HbA1C,BUN,UAER,kidney weight/body weight ratio,contents of AGEs,and RAGE increased significantly(P

Objective To explore the digital morphological and chromatic characteristics of erythrocytes infected with Plasmodium vivax. Methods The images of both normal and P. vivax infected erythrocytes were segmented and measured for morphologic parameters including area, length, breadth, perimeter, roundness, aspect ratio, equivalent circle diameter, as well as chromatic parameters including saturation and color (red, green, blue). A statistic analysis was performed for these parameters. Results Both morphological and chromatic parameters showed high significant differences between the normal and the infected erythrocytes, and high significant differences between the normal and the erythrocytes infected with different stages of P. vivax. Conclusion The differences mentioned above could be used as the basis for automatic identification of P.vivax in thin peripheral blood smears.

Objective To investigate the effect of preconditioning electrostimulation of fastigial nucleus (FNS) on the neuronal mitochondrion of rats early after cerebral ischemia. Methods Forty Wistar rats were used and divided into 5 groups: a normal control group, a sham FNS group and 3 FNS groups. The FNS of the rats in the FNS groups was conducted for 1 hr, 1 day or 7 days, respectively, before the models of middle cerebral artery occlusion(MCAO)were made with them. Three hours after the model was established, the animals were sacrificed and the water content of the brain of the ischemic side was measured. The neuronal mitochondrion was observed by electron microscope, and its Vv, specific volume (Sv) and specific surface (Ss) were analyzed. The rats in the normal control group were not given any special treatment. For the rats in the sham-FNS group, intrinsic neurons of FN were destroyed with ibotenic acid (IBO), and 5 days later, the FN was electrically stimulated, and 1 day later, MCAO models were made. Results Three hours after MCAO, the water content of the brain increased and neurological function score decreased in the sham-FNS group, while the Vv and Sv of neuronal mitochondrion increased and the Ss decreased, which were significantly different from those of the normal control group(P
