Objective To investigate the consumption status of iodized salt and iodine nutrition status of Tianjin residents,and to provide a scientific basis for iodine supplementation.Methods Sampling methods:① Salt iodine:According to The National Project of Surveillance on IDD,the iodine in salt samples from 18 Tianjin districts (counties) was tested between 2002 to 2011.②Iodine nutritional status of children:Investigation of iodine nutritional status of children was conducted four times in 2002,2005,2009 and 2011.In 2002 and 2005,two primary schools were selected in each district.By age,gender parity principle,40 subjects aged from 8 to 10 in each school were randomly selected to perform thyroid examination and 20 of them were selected to collect urine samples for determination of urinary iodine.In 2009,according to their sub-area positions in the north,the south,the east,the west and the center of each district,5 primary schools were selected in each town (if there were less than five towns in the district,all towns had been selected).Twenty subjects aged from 8 to 10 in each school were selected to collect urine samples for determination of urinary iodine.In 2011,probability sampling method (PPS) was used to select 30 primary schools,and then 40 children aged from 8 to 10 were randomly selected in each school to examine thyroids.At the same time,urine samples from 12 children of the 40 selected children were tested.③Iodine nutritional status of women of childbearing age:In 2007,2008 and 2010,150,50 and 60 women of childbearing age were selected in Hangu District,urine samples of them were collected for determination of urinary iodine.④Iodine nutritional status of pregnant and lactating women:In 2011,3 towns around each primary school were selected.Five pregnant and five lactating women were selected in each town,urine samples of them were collected for determination of urinary iodine.Test methods:①Salt iodine was tested by direct titration,while Sichuan salt and other reinforced edible salt by arbitration determination based on the General Test Method in Salt Industry-Determination of Iodide Ion (GB/T 13025.7-1999).②Thyroid was tested by B-type-ultrasound and judged according to Diagnostic Criterion of Endemic Goiter (WS 276-2007).③Urinary iodine was tested by the Method for Determination of Iodine in Urine by As3+-Ce4+ Catalytic Spectrophotometry (WS/T 107-2006).Results From 2002 to 2011,the consumption rate of qualified iodized salt,the rate of qualified iodized salt,the coverage rate of iodized salt,the rate of non-iodinated salt was 92.7％(43 489/46 926),97.4％(43 489/44 694),95.1％ (44 694/46 926) and 4.8％(2273/46 926),respectively.The median salt iodine was in the range of 29.2-36.7 mg/kg.Children's urinary iodine was monitored 4 times,the median urinary iodine was 228.0,221.5,191.8; and 194.7 μg/L,respectively.Children goiter rates were 2.1％(27/1258),1.6％(19/1186) and 2.1％(26/1219) of the 3 times monitored.The median urinary iodine in pregnant and lactating women was 145.2 and 136.0 μg/L.The median urinary iodine in women of childbearing age was 130.7,196.1 and 229.5 μg/L,which increased with the increase of coverage of iodized salt.Conclusions The iodine nutrition of Tianjin residents,women of childbearing age and lactating women are at appropriate level.The iodine nutrition of pregnant women is lower than appropriate level.Recommended salt iodine level in our city is 30 mg/kg,or 25 mg/kg for ordinary residents,and 30 mg/kg for pregnant women.

Objective To investigate the prevalence of adult osteofluomsis in the endemic fluomsis areas in Tianjin and to provide scientific foundation for endemic fluorosis.Methods Stratified sampling in 55 villages were selected in 3 areas with slight,moderate and severe fluorosis regions in Tianjin from April to June in 2008.Water fluorine were tested and clinical osteofluorosis examinations were conducted to the population aging 16 and above in the villages.Tweenty villages were selected randomly in the slight,moderate and severe fluorosis regions.X-ray osteofluorosis examination were conducted to patients and suspected patients in these 20 villages.Results The geometric mean fluoride content in the water for the 3 areas were 1.35 mg/L,3.44 mg/L,5.49 mg/L,respectively.The prevalence of osteofluorosis were 36.7%(44/120),20.6%(33/160),39.4%(43/109),respectively.The prevalence of osteofluorosis Was increased gradually(r=0.534,P<0.01)and the symptoms and signs of the disease were more serious(H=84.813,P<0.01).The prevalence of X-ray diagnosis Was increased gradually(r=0.990,P<0.01)and signs of the disease were more severe(H=25.169,P<0.01)with an increase in age.There was no statistical significance of prevalence rate of osteofluorosis between males and females,regardless if it Was a clinical diagnosis(X2=0.343,P>0.05)or an X-ray diagnosis(X2=3.532,P>0.05).Conclusions Adult osteofluorosis to a certain extent is still prevalent in the fluorosis areas in Tianjin.Endemic fluorosis is still rampant.Improving water in fulorosis areas should be mandatory.

The level of serum soluble interleukin-2 receptor(sIL-2R)was measured in 103 patientswith hepatitis B and 26 hepatitis B virus(HBV)carriers by enzyme-linked assay.The sIL-2Rconcentration were elevated significantly in each type of hepatitis B patients and HBV carriers,compared with control group(P

OBJECTIVETo study the ECG features in children with dilated cardiomyopathy (DCM), and related factors for the occurrence of arrhythmia secondary to DCM.

METHODSData from 68 children with DCM from January 1998 to March 2011 were studied. The children were classified into three groups: severe arrhythmia (n=42), non-severe arrhythmia (n=20) and non-arrhythmia (n=6). Left ventricular end diastolic diameter (LVED), left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS) were compared.

RESULTSAbnormal ECG results were found in all of the 68 children with DCM. Sinus tachycardia (91%) and ectopic pulsatile (86%) were common. LVED in the severe arrhythmia group (74±6 mm) was greater than that in the non-severe arrhythmia group (65±4 mm; P<0.05) and non-arrhythmia group (61±3 mm; P<0.05). LVED in the non-severe arrhythmia group was also greater than that in the non-arrhythmia group (P<0.05). LVEF and LVFS in the severe arrhythmia group were (30±11)% and (22±4)%, respectively, which were lower than those in the non-severe arrhythmia group［(37±12)% and (28±5)%, respectively］and non-arrhythmia group［(45±9)% and (34±7)%, respectively］(P<0.05). There were also significant differences in the LVEF and LVFS between the non-severe arrhythmia and non-arrhythmia groups (P<0.05).

CONCLUSIONSThe common abnormal ECG findings are sinus tachycardia and ectopic pulsatile in children with DCM. Arrhythmia is one of the main clinical manifestations of DCM. The occurrence of arrhythmia is associated with the left ventricular size and heart function.

This study is to explore new lead compounds by inhibition of Pin1 for anticancer therapy using temperature sensitive mutants. As Pin1 is conserved from yeast to human, we established a high-throughput screening method for Pin1 inhibitors, which employed yeast assay. This method led to the identification of one potent hits, 8-11. In vitro, 8-11 inhibited purified Pin1 enzyme activity with IC50 of (10.40 +/- 1.68) micromol x L(-1), induced G1 phase arrest and apoptosis, showed inhibitory effects on a series of cancer cell proliferation, reduced Cyclin D1 expression, was defined as reciprocally matched for protein-ligand complex in virtual docking analysis and reduced cell migration ability. In vivo, we could observe reduction of tumor volume after treatment with 8-11 in xenograft mice compared with vehicle DMSO treatment. Altogether, these results provide for the first time the involvement of 8-11 in the anticancer activity against Pin1.

To determine the role of vagi in heart rate variability, conscious rabbits were employed and electrocardiogram was recorded under conditions of bilateral vagi intact, unilateral vagotomy, and bilateral vagotomy. The variability of RR intervals (RRI) was analyzed using power spectrum and approximate entropy (ApEn). The results showed that the values of high frequency power (HF) component, low frequency power (LF) component and ApEn in animals with bilateral vagi intact were the highest, but the LF/HF ratio was the lowest; unilateral vagotomy decreased ApEn, right vagotomy increased LF/HF ratio but left vagotomy did not; the LF/HF ratio increased while ApEn decreased significantly in animals with bilateral vagotomy. It is suggested that the variability of RRI is mainly regulated by the vagi and the role of right vagi is more important than that of the left. When measuring heart rate variability, the results obtained with conventional method are consistent with those with nonlinear method.

OBJECTIVETo explore the effect of the treatment for long-term disease-free survival (DFS) of post-remission patients with acute myeloid leukemia (AML).

METHODSTwenty-nine AML patients with completely remission (CR) and 17 with partial remission (PR) were treated with Chinese medicine, Longchan Cigu Decoction 1 dose per day and Lingxiong Piaoling Powder 7 doses per month, and combined with DA or HA regimen of chemotherapy one course per year. Patients peripheral blood picture, bone marrow smear, biopsy and human leukocyte antigen DR (HLA-DR) cells were examined before and after treatment, and their disease-free survival (DFS) was followed up.

RESULTSAfter treated with above mentioned treatment for 2 months, percentage of patients with normal peripheral blood count increased, including patients with WBC > or = 4.0 x 10(9)/L raised from 46% to 70%, with Hb > or = 120 g/L from 17% to 46% and with PLT > or = 100 x 10(9)/L from 63% to 85%; nucleated cell volume in bone marrow increased from 35.83 +/- 28.42% to 60.46 +/- 17.73% (P < 0.01); HLA-DR cell was also increased significantly from 10.55 +/- 4.95% to 14.84 +/- 4.94%, (P < 0.01); while the residual leukemia cells were not increased in one year, from 5.90 +/- 5.09% before and 5.82 +/- 2.42% after treatment (P > 0.05). The maximal DFS in patients was 123 months. The 3-year survival rate was 64.15 +/- 1.96% and 5-year survival rate was 51.19 +/- 16.25%.

CONCLUSIONThe integrative Chinese and western medicine treating program used in this study is beneficial for the long-term treatment of AML patients after complete remission.
