Objective To work out the suitable iodine content in iodized salt among general population in Enshi Autonomous prefecture,Hubei province by determination of the iodine content in salt.Methods The method of direct titration was used to determine the iodine content in salt samples collected from residents in natural villages sampled from four directions of east,west,south and north in each township which was sampled from five directions of east,west,south,north and center in each city(county) in Enshi Autonomous prefecture,and salt samples were collected in Hubei Salt Industry Group Co.,Limited.Enshi Branch in 2011.The method of three-days weighing was used to estimate the resident's daily per capita intake of iodized salt.The appropriate iodine content for general population in salt was worked out according to the iodine content in salt from households and enterprises in Enshi Autonomous prefecture,the amount of iodine loss in iodized salt,the amount of per capita daily intake of iodized salt and the national iodine nutrition monitoring results.Results The median of iodine content in salt from residents and the production enterprises in 2011 was 33.5 mg/kg and 34.7 mg/kg,respectively.The residents' per capita salt intake was 10.9 g,actual intake of iodine wss 335.0 μg/d.Iodine content in iodized salt was 20 mg/kg ±30％ for the general population,actual intake of iodine was 149.4-250.4 μg/d.Conclusions The residents iodine intake is higher in Enshi Autonomous prefecture.Considering the comprehensive factors,including food iodine,water iodine,and iodine cooking loss,that affect the intake of salt iodine,the appropriate iodine content in iodized salt is 20 mg/kg ± 30％ for the general population.

OBJECTIVETo investigate the effects of combined transplantation of neural stem cells (NSC) and olfactory ensheathing cells (OEC) on the motor function of rats with intracerebral hemorrhage.

METHODSIn three days after a rat model of caudate nucleus hemorrhage was established, NSCs and OEC, NSC, OEC (from embryos of Wistar rats) or normal saline were injected into hematomas of rats in combined transplantation group, NSC group, OEC group, and control group, respectively. Damage of neural function was scored before and in 3, 7, 14, 30 days after operation. Tissue after transplantation was observed by immunocytochemistry staining.

RESULTSThe scores for the NSC, OEC and co-transplantation groups were significantly lower in 14 and 30 days after operation than in 3 days after operation (P < 0.05). The scores for the NSC and OEC groups were significantly lower than those for the control group only in 30 days after operation (P < 0.05), while the difference for the NSC-OEC group was significant in 14 days after operation (P < 0.05). Immunocytochemistry staining revealed that the transplanted OEC and NSC could survive, migrate and differentiate into neurons, astrocytes, and oligodendrocytes. The number of neural precursor cells was greater in the NSC and combined transplantation groups than in the control group. The number of neurons differentiated from NSC was significantly greater in the co-transplantation group than in the NSC group.

CONCLUSIONCo-transplantation of NSC and OEC can promote the repair of injured tissue and improve the motor function of rats with intracerebral hemorrhage.

Objective Little study has been done on the relationship between neutrophil-to-lymphocyte ratio ( NLR) and u-rine-to-creatinine ratio ( UACR) in patients with type 2 diabetes mellitus ( T2DM) .The article aimed to investigate the relationship be-tween NLR and UACR in T2DM patients. Methods 121 T2DM patients in our hospital from July 2015 to December 2015 were en-rolled and divided into patients with diabetic kidney disease (DKD) group(n=49) and non-DKD group(n=72).In accordance with UACR levels, the patients were divided into normoalbuminuria group ( n=72, male UACR<2.5 mg/mmol, female UACR<3.5 mg/mmol), microalbuminuria group ( n=33, male 2.5 mg/mmol≤UACR<30 mg/mmol, female 3.5 mg/mmol≤UACR<30 mg/mmol), and high-grade proteinuria group ( n=16, UACR≥30 mg/mmol ) . Clinical data and biochemical index were collected , which includes course of diabetes , glycosylated hemoglobin ( HbA1c ) , 25-OH vita-min D, and fasting/postprandial blood glucose/insulin /c-peptide, followed by analysis on the risk factors of DKD . Results NLR was significantly increased in DKD group compared to non-DKD group (2.14±1.06 vs 1.76±0.76, P=0.025) and was in significant relation with UACR (r=0.273, P=0.003).No significant difference was found among patients with normoalbuminuria , microalbuminuria, and macroalbuminuria(P>0.05).Logistic regression analysis revealed NLR (OR=1.829, 95%CI:1.051-3.183, P=0.033), course of di-abetes (OR=1.142,95%CI:1.062-1.229, P<0.001) and lipoprotein a (OR=1.026, 95%CI:1.001-1.051, P=0.039) as risk fac-tors for DKD. Conclusion It's the first report of the relationship between NLR and UACR , indicating NLR should be paid attention in patients with T2DM.

BACKGROUNDAtopic dermatitis (AD) is an inflammatory skin disease characterized by chronic recurrent dermatitis with profound itching. Most patients have personal and/or family history of atopic diseases. Several criteria have been proposed for the diagnosis of AD. Although the clinical features of childhood AD have been widely studied, there has been less large-scale study on adult/adolescent AD. The aim of this study was to investigate the clinical features of adult/adolescent patients with chronic symmetrical eczema/AD and to propose Chinese diagnostic criteria for adult/adolescent AD.

METHODSA hospital-based study was performed. Forty-two dermatological centers participated in this study. Adult and adolescent patients (12 years and over) with chronic symmetrical eczema or AD were included in this study. Questionnaires were completed by both patients and investigators. The valid questionnaires were analyzed using EpiData 3.1 and SPSS 17.0 software.

RESULTSA total of 2662 valid questionnaires were collected (1369 male and 1293 female). Of all 2662 patients, 2062 (77.5%) patients had the disease after 12 years old, while only 600 (22.5%) patients had the disease before 12 years old, suggesting late-onset eczema/AD is common. Two thousand one hundred and thirty-nine (80.4%) patients had the disease for more than 6 months. One thousand one hundred and forty-four (43.0%) patients had a personal and/or family history of atopic diseases. One thousand five hundred and forty-eight (58.2%) patients had an elevated total serum IgE and/or eosinophilia and/or positive allergen-specific IgE. Based on these clinical and laboratory features, we proposed Chinese criteria for adult/adolescent AD. Of all 2662 patients, 60.3% were satisfied with our criteria, while only 48.2% satisfied with Hanifin Rajka criteria and 32.7% satisfied with Williams criteria, suggesting a good sensitivity of our criteria in adult/adolescent AD patients.

CONCLUSIONLate-onset of eczema or AD is common. The clinical manifestations of AD are heterogeneous. We have proposed Chinese diagnostic criteria for adolescent and adult AD, which are simple and sensitive for diagnosis of adult/adolescent AD.

OBJECTIVETo explore the mechanism of hyperthermia inducing infertility by observing the expression of glial cell line-derived neurotrophic factor (GDNF) in rat Sertoli cells cultured in vitro at different temperatures.

METHODSUsing combination enzyme digestion and selective adhesion, we isolated Sertoli cells from male Wistar rats and cultured them in vitro at different temperatures, followed by observation of the changes in their adhesion and morphology and identification by FasL immunohistochemical staining. We divided the Sertoli cells into a control group (35 degrees C) and four experimental groups (36 degrees C, 37 degrees C, 38 degrees C, and 39 degrees C), measured their proliferation by CCK-8, observed their morphology and structure by HE staining, and determined the expression of GDNF by RT-PCR, immunofluorescence and Western blot.

RESULTSSertoli cells were successfully isolated and in vitro-cultured, with a purity of (95.30 +/- 2.15)% (n = 10). The CCK-8 assay showed that the proliferation of the Sertoli cells was the highest at 36 degrees C, gradually decreasing with the temperature above 36 degrees C, and significantly inhibited at 39 degrees C (P < 0.01). Immunofluorescence revealed the expression of GDNF in the cytoplasm, with the highest fluorescence intensity at 36 degrees C. RT-PCR and Western blot exhibited a decreasing trend of the GDNF expression with the increasing temperature above 36 degrees C. There were statistically significant differences in the expression of GDNF between the control group and the four experimental groups (P < 0.01).

CONCLUSIONThe proliferation and GDNF expression of in vitro-cultured Sertoli cells differ significantly at different temperatures. At > 36 degrees C, the higher the temperature is, the lower the Sertoli cell proliferation and GDNF expression are. Our findings suggest that high temperature above 36 degrees C suppresses the function of Sertoli cells and may also damage spermatogenesis.
