Objective To master iodine intake ways of children in Yancheng (coastal) and Zhenjiang (inland) cities,analyze their urinary iodine difference and provide solid evidence for adjustment of salt iodine and adequate iodine intake level of local residents.Methods Totally 50％ counties were randomly selected in Yancheng and Zhenjiang cities and 5 towns were sampled in each county in 2014,local water iodine,domestic salt iodine,local eating habits and urine iodine of children 8-10 years old were investigated,and the influences of different iodine intake ways on urine iodine level were analyzed.Results The median of water iodine was 4.76 μg/Lin Zhenjiang (n =40) and 50.80 μg/L in Yancheng (n =50),the difference was statisticelly significant in two cities (Z =6.93,P ＜ 0.05).Totally 2 400 salt samples were tested,the mean of salt iodine was (24.20 ± 5.07) mg/kg in Yancheng (n =1 500) and (22.87 ± 2.77) mg/kg in Zhenjiang (n =900),the difference was statisticelly significant in two cityies (t =7.23,P ＜ 0.05).The salt intake level in Zhenjiang (10.69-± 9.00) g/d appeared to be higher than that in Yancheng (8.40 ± 3.57) g/d,but the difference was not statistically significant (t =1.62,P ＞ 0.05).Totally 1 200urine samples were tested,the urine iodine level of Zhenjiang got higher results (265.83 μg/L,n =450) than that of Yancheng (182.15 μg/L,n =750,Z =12.18,P ＜ 0.05).The ratio of water iodine intake/salt iodine intake was about 1 ∶ 4 in Yancheng and 1 ∶ 50 in Zhenjiang,while residents in Zhenjiang got 21％ of daily iodine through extra ways.Eating habits like eating out did not have significant impact on urine iodine.Conclusions Based on the water iodine level,Yancheng is considered to be a appropriate iodine level area while Zhenjiang is a lack region.However,Zhenjiang has a higher urine iodine level than Yancheng,which is more than adequate to the recommendation.Salt iodine is a main iodine source in both cities.In iodine appropriate and deficiency areas,eating habits and food choices may play a more important role than geochemical factors in iodine intakes among residents.

Study the serum level of HGF, Cys C and TGF-beta1 in type 2 diabetic nephropathy (DN), the infect of Pingshen decoction on those index. Selected 69 cases of 2 type DN and randomly divided into therapy group (36 cases) and control group (33 cases). The therapy group were treated with Pingshen decoction 1 dose/d, bid po. The control group were treated with NephritisShu tablet, 6 tablet, tid po. 8 weeks was a course. Before and after treatment, we examine the serum level of HGF, Cys C and TGF-beta1 by ELISA and immunonephelometry, and compare with 30 cases of healthy control group. The study demonstrates that before treatment, the serum level of HGF in both groups were significantly lower than healthy control group (P < 0.01), but Cys C, TGF-beta1 were significantly higher (P < 0.01). After treatment, the serum level of HGF of both groups were increased. The serum level of HGF of therapy group were significantly higher than of control group (P < 0.01), but the serum level of Cys C and TGF-beta1 were significantly lower than control group (P < 0.01). The serum level of HGF was correlated negatively with Cys C,TGF-beta1. In control group, the UAER, urine beta2-MG and quantity of 24-hour urine protein were significantly decreased after treatment (P < 0.01). The index of urine of therapy group were significantly lower than control group (P < 0.01). Results indicate that test of serum level of HGF and Cys C,TGF-beta1 of diabetic nephropathy have important clinical significance. Pingshen decoction can effectively intervene in the serum level of HGF and Cys C, TGF-beta1 and index of urine.

Objective To investigate the effect of Yanghe decoction serum on the proliferation of breast cancer stem cells HMLER90hi and its mechanism. Methods Twenty female Sprague-Dawley rats were randomly divided into low,medium and high dose groups containing drug serum and control group, in order to prepare the Yanghe decoction serum and blank serum. After 24 hours of drug intervention,the effects of each group on the proliferation of HMLER90hi cells at 24 h,48 h,and 72 h were detected by MTT assay. The expression of EphA4 and p50 mRNA in each group were detected by real-time fluorescence quantitative PCR. Results Compared with the blank control group,the cell proliferation activity of each dose group of Yanghe decoction significantly decreased at 24 h (0.818 ± 0.061, 0.706 ± 0.073, 0.587 ± 0.052 vs. 0.928 ± 0.075), 48h (0.760 ± 0.047, 0.638 ± 0.056, 0.510 ± 0.059 vs. 0.973 ± 0.095), and 72 h (0.672 ± 0.102, 0.508 ± 0.092, 0.448 ± 0.048vs.1.023 ± 0.099) (P<0.05 orP<0.01), respectively. After 24 h of drug intervention, compared with the control group, the expression of EphA4 mRNA (0.54 ± 0.07, 0.54 ± 0.07, 0.33 ± 0.04 vs.0.68 ± 0.09) significantly decreased, and p50 mRNA (0.69 ± 0.10, 0.54 ± 0.08, 0.41 ± 0.06vs. 0.85 ± 0.13) significantly decreased in each dose group of Yanghe decoction (P<0.05 orP<0.01).ConclusionsTheYanghe decoction can inhibit the proliferation of breast cancer stem cell HMLER90hi,and its mechanism may be related to its inhibition of the conduction of the juxtacrine pathway of monocyte macrophage.

The study was aimed to investigate the subcellular localization of mixed-lineage leukemia (MLL) and Menin proteins, and to explore the interaction between these two proteins. The recombinant eukaryotic cell expression vectors of pcDNA3.1-myc-MLL and pCMV-flag-Menin were constructed respectively, and transfected into the HEK293T cells. Immunofluorescence technique was used to observe the subcellular localization of the two proteins. Co-immunoprecipitation and Western blot methods were applied to evaluate the expression and interaction of the two proteins. The results showed that MLL and Menin proteins could be co-localized in cell nuclei, and the study of binding in vivo revealed that MLL protein could be detected in the immunoprecipitation complex of anti-FLAG, while Menin proteins could also be found in the immunoprecipitation complex of anti-MYC. It is concluded that MLL and Menin proteins co-localized in cell nuclei have same location and the interaction exists between MLL and Menin proteins.

Objective To evaluate the usefulness of narrow-band imaging with magnification in differentiating colorectal lesions, and assess for a learning curve, to gave help for the clinician, who want to carry out the technique. Method We retrospectively analyzed the clinical data of 289 patients who underwent NBI combined with magnification by four endoscopic physician, from June, 2015 to June, 2016, all the lesions were biopsied, endoscopic treatment or postoperative pathology and pathological examination, and the Sano classification control. All lesions were divided into three groups according to the NBI combined with magnifying endoscopy, these three sets included both lesions requiring endoscopic treatment (e.g. target lesions) and lesions that were not, or could not be, treated by endoscopy (e.g. nontarget lesions). Each physician examined the target or non-target lesion reached 15 cases as a group. By assessing the diagnostic accuracy of the four physicians for each group of lesions, an associated learning curve of NBI combined with magnifying endoscopy was developed. Result In 289 patients, 372 lesions were found by colonoscopy. NBI combined with magnifying endoscopy was 95.1%, 98.0% and 92.0%, respectively, in the identification of tumor and non-neoplastic lesions. The accuracy of the diagnosis of target and non-target lesions was significantly higher in group 2 than in group 1 [81.7% vs 95.1% (P = 0.010) and 71.7% vs 93.4% (P = 0.000)]. There was no significant difference in the diagnostic accuracy between group 2 and group 3 (P = 0.984 and P = 0.117). Conclusion It is very useful to use narrow-band imaging and Sano CP analysis in the differential diagnosis of colorectal lesions. The endoscopists who had never used NBI or no knowledge of NBI can have effective and stable diagnostic accuracy after using NBI with magnification to diagnose 15 target and non-target lesions respectively.

Objective To understand the drinking water type fluorosis in Jiangsu Province, dynamically monitor the disease trends, and to evaluate the operation effect of the water project comprehensively. Methods Twenty-six fluorosis districts and counties in Xuzhou, Lianyungang, Suqian, Huaian and Yancheng were selected as the monitoring sites. The change of water improvement engineering and the value of water fluoride were surveyed and tested. There were three different situations of changed water: the water improvement engineering operated normally was the first, the water improvement engineering operated abnormally or water fluorine excesses the standard was the second,and without water improvement was the last.The teeth of children aged 8 to 12 years were checked according to the method of Dean. The skeletal fluorosis of adults was checked according to "Diagnostic Criteria of Endemic Skeletal Fluorosis"(WS 192-2008) by X-ray inspection. Results The normal operation rates of changed water project from 2011 to 2015 were 100.00% (30/30), 85.29% (29/34), 82.50% (33/40), 95.92% (47/49),and 97.83%(45/46),and the excessive rates of water fluorosis for normal operating engineering were 13.33%(4/30),17.24%(5/29),9.09%(3/33),14.89%(7/47),and 11.11%(5/45).The dental fluorosis detection rates of children aged 8 to 12 years were 33.68% (194/576), 28.30% (711/2 512), 36.25% (1 577/4 350), 22.06% (837/3 794), and 20.44% (903/4 417) from 2011 to 2015, the differences were statistically significant (χ2= 190.952, P < 0.05). The dental fluorosis detection rates in the three situations of water changed annually was statistically significant (χ2=129.336, 130.402, 21.419, P < 0.05). The detection rates between three different water conditions were 21.88% (2 857/13 057), 57.23% (1 156/2 020), 36.54%(209/572), and the differences were statistically significant (χ2=206.295, P < 0.05). Differences between the villages with water improvement engineering changed but not worked and the villages with water improvement engineering changed and worked well and the villages without the water improvement engineering were statistically significant(χ2=200.861,36.336,P<0.0125).The difference of detection rates between the villages with normal operation and the villages without water improvement was not statistically significant(χ2=2.131, P>0.0125).The X-ray detection rates of skeletal fluorosis in adults from 2011-2015 were 17.83% (51/286), 16.61% (49/295), 15.36% (51/332), 10.95% (53/484), and 5.16% (16/310); urinary fluoride range was 0.02 - 22.0 mg/L; the geometric average was 0.67 - 4.06 mg/L, there was no statistical significant difference of skeletal fluorosis distribution annually(χ2=6.060, P > 0.05). Conclusion The general condition of drinking water type fluorosis in Jiangsu Province from 2011 to 2015 is gradually under control, but the engineering operation and water quality improvement still need to be improved; water change project not functioning or with excess fluorine is more harmful to children's teeth.

OBJECTIVETo explore the effect of ginkgo leaf extract (GLE) on vascular endothelial function (VEF) in patients with early stage diabetic nephropathy (DN).

METHODSSixty-four patients were randomized equally by a randomzing digital table into two groups, the treated group and the control group. They were all treated for 8 weeks with conventional therapy for diabetes, but GLE tablets were given to the treated group additionally. Changes in VEF were estimated before and after treatment by ultrasonic examination of the brachial artery. In the meantime, changes in plasma levels of the von Willebrand factor (vWF), nitric oxide (NO) and endothelin-1 (ET-1) were observed as well.

RESULTSThe brachial arterial endothelium dependent dilating function in the treated group increased from 4.91+/-2.31% before treatment to 6.78+/-3.89% after treatment (P<0.05), while the level of vWF decreased from 182.05+/-64.13% to 128.56+/-48.98%, and that of NO increased from 50.16+/-24.64 micromol/L to 70.65+/-28.71 micromol/L (P<0.01). However, these indexes were not significantly changed in the control group after treatment (P>0.05).

CONCLUSIONGLE could decrease the plasma level of vWF, raise the plasma NO level and improve the endothelium dependent vascular dilating function in DN patients.
