Objective To assess the iodine nutritional status of special target population in coastal saltproducing areas and coastal non-salt-producing areas in Xiamen city,and to provide a basis for take appropriate measures for prevention of iodine deficiency disorders.Methods The Xiang-An salt-producing areas and the JiMei non-salt-producing areas were chosen as research spots in 2009.One sample of produced water and 2 samples of tap water were collected to test iodine level; 600 children aged 8 to 10 were selected and thyroid palpation was performed,besides,the urine sample and household salt sample were also collected for iodine determination.Sixty pregnant women,breasffeeding women,and 0 - 2 year old infants were recruited,respectively,and urine samples and household salt samples were collected to perform the determination of iodine level.Results The iodine levels in drinking water of Xiang-An district and Ji-Mei district were 3.23 and 6.05 mg/L,respectively.The consumption rates of edible qualified iodinated salt were 84.4％ (438/519) and 98.3％ (392/399),respectively.The goiter rates of children aged 8 - 10 were 3.03％(19/628) and 0.67％(4/600),respectively.The medians of urinary iodine were 202.80 and 238.40 μg/L,respectively.The proportions of urinary iodine level ＜ 50 μg/L were 3.5％ (14/405) and 1.0％(2/202),respectively.The medians of urinary iodine of the pregnant women were 120.55 and 153.35 μg/L,respectively,and the proportions of urinary iodine level ＜ 150 μg/L were 62.1％ (46/74) and 46.8％ (29/62),respectively.The medians of urinary iodine in three trimester were 173.10,144.75 and 101.90 μg/L,respectively,early trimester of pregnancy ＞ second trimester and third trimester (Z =6.151,3.052,all P ＜ 0.05),second trimester ＞ third trimester (Z =2.016,P ＜ 0.05 ).The medians of urinary iodine of the breastfeeding women were 131.20 and 104.35 μg/L,respectively.The proportions of urinary iodine level ＜ 100 μg/L were 35.3％ (24/68) and 46.7％(28/60),respectively.The medians of urinary iodine of the infants were 81.95 and 80.20 μg/L,respectively,the proportions of urinary iodine level ＜ 100 μg/L were 59.7％(37/62) and 61.6％(40/65),respectively,＜ 50 μg/L were 32.3％ (20/62) and 30.8％ (20/65),respectively.Conclusions The levels of iodine nutrition in pregnant women,breastfeeding women,and 0 - 2 year old infants from Xiang-An district and Ji-Mei district in Xiamen city are still below the desired level of iodine nutrition,and the infants and pregnant women in coastal salt-producing areas are poor in iodine nutrition,we should pay close attention.We should strengthen market supervision on iodized salt,carried out iodine nutrition monitoring on pregnant women,breasffeeding women,and infants,and disseminate knowledge of iodine nutrition among high-risk population should be carried out immediately.

OBJECTIVETo survey the prevalence of drug resistant HIV in Zhejiang province in 2009-2011.

METHODSWHO truncated sequential sampling technique was adopted annually by using 63, 62 and 57 samples of newly diagnosed as HIV positive and aged 16-25 years in Hangzhou, Ningbo and Wenzhou from 2009 to 2011, respectively. RNA was prepared and HIV pol region was amplified by RT-PCR and nested PCR. Pol genetic mutation associated with drug resistance was analyzed.

RESULTSThe success rates for sequence acquisition of the survey were 82.5% (52/63), 95.2% (59/62) and 94.7% (54/57) from year 2009 to 2011, respectively, and the main subtype was CRF01_AE (68.5% (37/54)-71.2% (37/52)). A total of 4 surveillance drug-resistance mutation (SDRMs), 2 SDRMs and 2 SDRMs were found by analyzing the 47 sequences each year, sampled from year 2009 to 2010, respectively, indicating that the prevalence of drug resistant HIV stains was moderate in 2009, and low for the next two years (2010-2011). A total of 8 individuals with drug resistant HIV stains found in this study were all infected by sexual transmission, especially in homosexual transmission (6 cases), and the main subtype was CRF01_AE (7 cases). SDRMs for protease inhibitor (PI), nucleotide HIV-reverse transcriptase inhibitor (NRTI) and non-NRTI (NNRTI) (L90M, T215S and Y188L) were all found in one case.

CONCLUSIONThe prevalence of drug resistant HIV stains in major areas with AIDS epidemic in Zhejiang province was low in 2009-2011.

Objective: To explore the relationship between plasma level of soluble urokinase plasminogen activator receptor (suPAR) and the severity of acute coronary syndrome (ACS) with its influence factors. Methods: A total of 321 consecutive patients with chest pain admitted in our hospital from 2015-03 to 2016-09 were studied. According to clinical presentation, laboratory test and coronary angiography (CAG), the patients were divided into 2 groups: ACS group, n=228 and Control group, the patients with normal coronary artery, n=93. Plasma levels of suPAR and high sensitive C reaction protein (hs-CRP) were measured by ELISA and compared between 2 groups. Results: The levels of plasma suPAR in ACS patients were significantly higher than those in the control group (OR= 0.104, 95％ CI: 0.048-0.223, P<0.01). In ACS group, the plasma suPAR level gradually increased with the increase of Gensini score, The sensitivity and specificity of the levels of suPAR were determined by ROC curve. The values of ACS were predicted to be 1.8 μg / L, the sensitivity was 0.732 and the specificity was 0.710. Multiple linear regression analysis showed that smoking, Gensini score and uric acid were the main factors affecting plasma suPAR levels. Conclusion: Elevated plasma suPAR level has been related to the severity of coronary stenosis in ACS patients, such relationship is superior to hs-CRP; suPAR might be worked as a new biomarker for predicting coronary stenosis and risk stratification in ACS patients.

Objective:Through phosphatidylinositol 3-kinase（PI3K）/protein kinase B （Akt）/mammalian rapamycin target protein （mTOR） signaling pathway， explore the effect of Zhigancao Tang on myocardial ischemia-reperfusion injury（MIRI）The role and mechanism of arrhythmia（ventricular tachycardia and ventricular fibrillation）. Method:The 72 SD rats were randomly divided into sham operation group，model group， Zhigancao Tang low，medium and high dose group（11.43，22.86，45.72 g·kg^-1），Wenxin granule group（2.43 g·kg^-1），continuous drug intervention for 10 days. Two hours after the last administration，the MIRI model of rat was prepared by ligating the left anterior descending coronary artery，and the changes of electrocardiogram were recorded. After successful modeling，blood and heart tissue were collected to detect the content of creatine creatine（CK），lactate dehydrogenase（LDH）and aspartate aminotransferase（AST）in the serum, the enzyme-linked immunoassay（ELISA） method was used to detect cardiac troponin（CtnI）content, immunohistochemical detection of myocardial PI3K，Akt，mTOR expression. Western blot was used to detect the myocardial autophagy-related protein microtubule-associated protein 1 light chain 3（LC-3），autophagy markers Beclin1 and PI3K/Akt/mTOR signaling pathway related protein expression and phosphorylated p-PI3K，p-Akt，p-mTOR levels. Result:In model group， 100% of ventricular tachycardia and 91.67% of ventricular fibrillation occurred. Compared with sham operation group， the serum levels of CK，LDH，AST，and CtnI in the model group were significantly increased（P<0.01），PI3K，Akt，mTOR AOD values in myocardial tissue were significantly increased （P<0.01），the relative expression of the ratio of LC3-Ⅱ/LC3-Ⅰ and Beclin1 was significantly increased（P<0.01），p-PI3K/PI3K，p-Akt/Akt，and p-mTOR/mTOR were significantly reduced （P<0.01）. Compared with model group， the incidence of ventricular tachycardia and ventricular fibrillation in the high-dose Zhigancao Tang group was significantly reduced （P<0.01），and the duration was the shortest compared with other administration groups（P<0.01）， CK，LDH，AST level and CtnI content were significantly reduced（P<0.01）， the expression of PI3K，Akt and mTOR of Zhigancao Tang group was significantly decreased with increasing dose（P<0.01）， the expression of LC-3 and Beclin1 was accompanied by Zhigancao Tang increase of each dose group of soup had different degrees of decrease （P<0.01），while the expression ratio of PI3K/Akt/mTOR-related protein was significantly increased （P<0.05，P<0.01）. Conclusion:Pretreatment of Zhigancao Tang can reduce the abusually elevated cardiac enzymes CK, LDH, AST and CtnI, inhibit excessive autophagy of cells, and up-regulate the expression of PI3K, Akt and mTOR, indicating that the anti-MIRI arrhythmia effect of Zhigancao Tang may be related to the PI3K/Akt/mTOR signaling pathway.
