Objective To study whether the measure of consumption of iodized salt to prevent iodine deficiency disorders could lead to residents excessive iodine intake in the coastal areas in China.Methods A large population-based cross-sectional study was carried out in four typical costal provinces along the coastline from north to south,including Liaoning,Shanghai,Zhejiang and Fujian.In addition to survey all of its area of Shanghai,the other three provinces' investigation was carried out at urban and rural levels,respectively,including 5 costal cities,5 costal villages and 3 inland rural areas(as a control point) in each province.In each investigated spot,the local water iodine,residents qualified iodized salt consumption rate,per capita daily intake of salt and urinary iodine levels in different populations were investigated.Results A total of 7552 copies of drinking water samples,7996 salt samples and 9873 urine samples of different populations(adults,lactating women,pregnant women and children) were collected from the 4 provinces.Except the coastal cities and counties of Zhejiang province,the qualified iodized salt consumption rates at household were all greater than 90％ in the investigated spots.The median urinary iodine(MUI) of adults and children investigated in the costal areas were in the range of 100 - 299μg/L.The MUIs of lactating women of all investigated areas were all greater than 100 μg/L.The MUI of pregnant women was at an insufficient iodine level which was lower than 150 μg/L in Shanghai,the costal cities of Zhejiang and the coastal counties of Fujian.Conclusions The overall level of iodine nutrition of coastal residents is appropriate; and it is insufficient among pregnant women in some coastal areas; coastal areas should adhere to the salt iodization measures to control iodine deficiency disorders.

OBJECTIVETo establish the comparative proteomic profiles of retinoid acid (RA) resistant human acute promyelocytic leukemia (APL) NB4-R1 cells before and after apoptosis induced by realgar (tetra-arsenic tetra-sulfide, As4S4).

METHODSFirst a serial of assays were performed using MTT, transmission electron microscopy, Annexin V FITC/PI double-stain, flow cytometry and confocal laser scanning microscopy to qualitatively and quantitatively observe the in vitro apoptosis inducing effect of realgar on RA-resistant cells. Then the comparative proteomic profile before and after NB4-R1 apoptosis was established using high-resolution two-dimensional electrophoresis system.

RESULTSThe inhibition effect of realgar on NB4-R1 cell growth was dose and time dependent. The 24-h 50% inhibiting concentration (IC50) was 24.06 +/- 0.19 micromol/L, and the 48-h IC50 9.50 +/- 0.13 micromol/L, and 72-h IC50 6.55 +/- 0.03 micromol/L, respectively. 24 h and 48 h were the early and late phase of major NB4-R1 apoptotic cell populations induced by 25 micromol/L realgar respectively. Differential proteomic profiles before and after realgar induced NB4-R1 apoptosis were successfully established. Averagely 1069, 975 and 893 spots could be detected of the untreated group (R0), the 24-h treatment group (R24), and the 48-h treatment group (R48), respectively by ImageMaster 2D Platinum Software. The matching rate between R24 and R0 was 79.94% and that between R48 and R0 69.33%, and that between R24 and R48 71.91%.

CONCLUSIONDifferential proteomic profiles of realgar induced NB4-R1 apoptosis were successfully established for the first time, which provided a basis for comprehensively understanding the signal transduction of realgar induced apoptosis in RA-resistant APL cells, also for screening new bio-markers and drug targets of hematopoietic malignant tumor.

Background Lattice corneal dystrophy (LCD) is a progressive disease,whose clinical features are varied in different stages.It is rarely be reported that clinical findings of different stages and factors of promoting the occurrence and development on LCD in a family.Objective The aim of this study was to identify the characteristics of the pedigree and clinical features of different stages in a LCD family,and further to discuss its influence factors.Methods A cross-sectional study was performed in this study.A Chinese family with LCD was enrolled in Shenzhen Eye Hospital from 2015 to 2016.Questionnaires for disease-related history,visual acuity measurement,ocular anterior segment examination and color photography were carried out for all the members of the family.In addition,anterior segment OCT (AS-OCT),laser scanning confocal microscope and corneal endothelium microscope were used to observe the morphology of corneal stroma and changes of corneal endothelial cells.The pedigree chart was drawn by Cyrillic2.1 software and analyzed based on Mendel law.Results This family included 5 generations of 73 members.Patients with LCD were found in each generation with similar morbidity in different gender,which followed the law of autosomal dominant inheritance.Eleven patients were found in 49 members related with Ⅲ1 of this family with the prevalence rate of 22.45％ and onset age at 21-50 years old,and the course of disease was 3-34 years.All of the members had no systemic disease except for two patients (Ⅲ 1 and Ⅲ 5) with hypertension.In the early stage of LCD,some bifurcate striolae appeared in the patients' corneal stroma without symptoms for many years.In the progressive stage,there was corneal irritation symptom accompanying with vision's decrease in the eyes with LCD.The bifurcate striolae were increased,widened and interwoven into lattice lines that the boundaries gradually became fuzzy,then corneal macula was formed because of recurrent corneal infiltration,and eventually resulted in corneal leucoma.High reflection corresponding to the pathologic region was showed by laser scanning confocal microscope and AS-OCT.No significant differences were found in corneal endothelial cell density and the percentage of hexagonal cells between LCD patients and normal phenotype families (t =1.887,P=0.075;t=-0.719,P =0.481).Penetrating keratoplasty was performed in a patient with corneal opacity and serious corneal opacity occurred near the surgical incision one year after the surgery.One patient was diagnosed as LCD 2 years after laser assisted in-situ keratomileusis.One patient was a welder.Conclusions LCD is autosomal dominant inheritance in the family.The clinical manifestations of LCD in the early,progressive and late stage can be seen in the pedigree,which offers a reference for ophthahnologists.Corneal surgery and lesion may induce the onset or aggravation of LCD.

This study examined the effect of electro-acupuncture (EA) combined with transcranial magnetic stimulation (TMS) therapy at different time windows on learning and memory ability of rats with cerebral infarction and the underlying mechanism. Two hundred SD rats were randomly divided into four groups: normal group, sham-operated group, model group and EA+TMS group, and each group was then divided into five sub-groups in terms of the different time to start treatment post operation: 6, 12, 24, 48 and 72 h. Cerebral infarction models were established in the model and the EA+TMS groups by left middle cerebral artery occlusion/reperfusion (MCAO/R). After treatment for 14 d, the Morris water maze test was applied to examine the spatial learning and memory abilities of rats. In infarcted area, the expression of caspase-3 was immunohistochemically detected, and real-time fluorescent quantitative PCR was used to measure the expression of Bcl-2 mRNA. The results showed that in EA+TMS group compared with model group at the same treatment time windows, the escape latency was substantially shortened, the expression of caspase-3 was considerably decreased and the expression level of Bcl-2 mRNA significantly increased (P<0.05). In the EA+TMS sub-groups, the escape latency was shortest, the expression level of caspase-3 lowest, and the expression level of Bcl-2 mRNA highest at the treatment time window of 24 h. It was concluded that EA combined with TMS can promote neurological function of rats with cerebral infarction by increasing the expression level of Bcl-2 mRNA and decreasing the expression of caspase-3. The best time window is 24 h after perfusion treatment to ischemia.

AIM:To explore relationship between the normal strehl ratio ( SR ) values of total aberrations/SR values of total higher-order aberrations and modulation transfer function ( MTF ) at total corneal at different pupil diameters in normal population.
METHODS: To exam the SR values of total aberrations and SR values of total higher-order aberrations of total corneals in 200 people ( 400 eyes ) using SIRIUS 3D topography system and analysis the corresponding root-mean-square ( RMS) .
RESULTS: The subjects with different pupil diameters (3. 0, 5. 0, 6. 0, 7. 0mm)'s exam results of total corneal were as following:SR value of total aberrations 100’(0. 45±0. 12), (0. 25±0. 06), (0. 17±0. 05), (0. 13±0. 04); SR value of total higher order ab cerrations 100’(0. 69±0. 14), (0. 34±0. 07), (0. 24±0. 05), (0. 16±0. 04);SR value of total aberrations 200’(0. 45±0. 12), (0. 24±0. 06), (0. 20±0. 04), (0. 16±0. 03); SR value of total higher order aberrations 200’(0.70±0. 13), (0. 35±0. 07), (0. 27±0. 06), (0. 20±0.04 ) . The SR values of each group decreases with the increases of pupil diameters. The SR values of total aberrations and SR values of total higher - order aberrations at total corneals are negatively correlated with corresponding RMS value. When the pupil diameter is small, the SR value of total aberrations is more related to higher frequency region of MTF. When the pupil diameter is big, the SR value of total aberrations is more related to lower frequency region of MTF.
CONCLUSION: The visual performance of normal people can be well reflected by SR values of total aberrations and SR values of total higher - order aberrations at total corneal.

The purpose of this study is to explore depression metabolic markers in rat hippocampus and to investigate the anti-depressant effect of genipin and its mechanisms using nuclear magnetic resonance (NMR) metabonomics. Chronic unpredictable mild stress (CUMS) procedure was conducted to establish the depressive rat model. At the beginning of the third week, genipin low dose (25 mg x kg(-1)), middle dose (50 mg x kg(-1)), high dose (100 mg x kg(-1)), and venlafaxine (50 mg x kg(-1)) were given to the CUMS rats separately once daily for two weeks except control and model groups. Rat hippocampus was analyzed by 1H NMR based metabonomics after drug administration for 2 weeks. Significant differences in the metabolic profile of rat hippocampus of the CUMS treated group and the control group were observed with metabolic effects of CUMS including decreasing in glycine and N-acetylaspartate, increasing in inositol, glutamate, lactate, glutamine, taurine and alanine. Genipin showed ideal antidepressive effects at a dose of 50 mg x kg(-1) in rats, decrease of inositol, glutamate, lactate, alanine were observed, while glycine and N-acetylaspartate were increased. Important influence has been found on normal nervous system function of these significant changed metabolites, which suggests that the antidepressant effect of genipin may be played by enhancing the activity of neurons in hippocampus, repairing and improving the function of the neuron. The metabonomics approach is an effective tool for the investigation of the anti-depressant effect and pharmacologic mechanisms of genipin.
