Emphasis on individual health actions as the cornerstone for Healthy China initiative / 中华医院管理杂志

Healthy China action is a key to the Healthy China initiative. Promoting Healthy China is faced with such challenges as coordinating actions of the society at large, and reliance on individual incentives. To overcome these difficulties, the authors propose to adopt a concentrating-on-the-main-points approach. As proposed, the government should focus on the key points of the overall situation and uphold the Healthy China initiative, and base all the actions on individual health actions as the focus. Community health service centers are expected to manage individual health actions so as to cover the population of the country. In this view, the government should formulate the policy of initiating and managing individual health actions by community health service centers.

Hospitalization rates for influenza-associated severe acute respiratory illness in children younger than five years old in Suzhou of China, 2016-2018 / 中华预防医学杂志

We analyzed the influenza surveillance data of Children′s Hospital of Suzhou University from 2016 to 2018 and estimated the hospitalization burden of children under 5 years old due to influenza infection in Suzhou. The results showed that the influenza virus positive rate of 1 451 severe acute respiratory infection (SARI) cases in Children′s Hospital of Suzhou University was 13.6% (95%CI: 11.8%-15.3%; 197 cases), among which the influenza pandemic intensity in 2017-2018 was relatively high, and A/H1N1 was the main pandemic virus. It was estimated that the hospitalization rate of influenza-related SARI in children under 5 years old in Suzhou was 6.9‰ (95%CI: 6.6‰-7.2‰), among which the hospitalization rate of children aged<6 months was higher, up to 11.4‰ (95%CI: 9.9‰-12.8‰).

Expression of TAK1, pTAK1 proteins and density of tumor associated macrophages in pancreatic carcinoma / 中华胰腺病杂志

Objective To investigate the expression of TGF-β activated kinase1 (TAK1),phosphoryted TAK1 (p-TAK1) and the density of tumor associated macrophages (TAM) in human pancreatic carcinoma tissues and pairing adjacent normal pancreatic tissues,and explore their relationship.Methods The expression of TAK1,p-TAK1,CD68 (the marker of tumor associated macrophages) proteins in 57 samples of pancreatic cancer tissues and 35 samples of pairing adjacent normal pancreatic tissues were detected by immunohistochemical method,then the density of TAM was evaluated.The relationship between the protein expression and TAM,and the relationship between them and clinicopathologic parameters were examined using SPSS 18.0 software,and the independent risk factors of TNM staging were analyzed by multivariate logistic regression.Results TAK1 and p-TAK1 were positively expressed in 42.1％ (24/57) and 40.4％ (23/57) pancreatic carcinoma tissues,significantly higher than adjacent normal pancreatic tissues [14.3 ％ (5/35) and 11.4％ (4/35)];the proportion of pancreatic carcinoma tissues with high density TAM was 38.6％ (22/57),higher than that of adjacent pancreatic tissues [8.6％ (3/35)],the differences were statistically significant (P＜0.05).TAK1 expression was positively related to tumor size,tumor differentiation,lymph node metastasis,distant metastasis and clinical staging;p-TAK1 expression was positively related to tumor differentiation,lymph node metastasis,distant metastasis and clinical staging;the density of TAM was positively related tumor differentiation,lymph node metastasis,distant metastasis and clinical staging (all the P values were less than 0.05).The expression of TAK1 and p-TAK1were positively correlated with the density of TAM (P ＜0.001).Multivariate logistic regression analysis showed that high density of TAM was independently associated with advanced clinical staging (P =0.002,OR =129.5,95％ CI 6.2 ～2718.6).Conclusions TAK1 pathway and TAM may play an important role in the pathogenesis and progression of pancreatic cancer,and there may be synergy effect between them.

Determination of 26 Mycotoxins in Feedstuffs by Multifunctional Cleanup Column and Liquid Chromatography-Tandem Mass Spectrometry / 分析化学

A rapid high-throughput method for the determination of 26 mycotoxins involving multifunctional cleanup column coupled with liquid chromatography-tandem mass spectrometry ( LC-MS/MS) was developed and validated for the determination in feedstuffs. The feedstuff samples were extracted by ultrasonic treatment for 1 hour and the extraction solvent was acetonitrile/water/formic acid (84:15. 9:0. 1, V/V). 1 mL of the supernatant layer was purified by a commercial Mycospin 400 multifunctional cleanup column, then dried and re-dissolved by 0. 25 mL water/methanol/formic acid (95:4. 9:0. 1, V/V) in a vial for injection into the LC-MS/MS system. Chromatographic analyses were carried out on a reversed phase C18 column and using a gradient elution with 0. 1% formic acid aqueous solution and 0. 1% formic acid methanol solution. The mass spectrometer was operated in a multiple reaction monitoring ( MRM) mode that selected one precursor ion and two product ions for each target compound. Validation studies were carried out in maize and soybean meal as representative matrixes. The most target compounds had different level of matrix effects. So, matrix-matched calibration was adopted for quantification. Mean recoveries from spiked samples at three levels ranged from 61 . 9% to 119 . 5% with relative standard deviations of 0 . 8%-18 . 6%. Limits of quantification ranged from 0. 5 μg/kg to 25 μg/kg.
