AIM:Heart failure is characterized by immune activation leading to production and release of proinflammatory cytokines .Inter-leukin 17A (IL-17A) is a proinflammatory cytokine and multiple lines of evidence from animal and human studies suggest crucial roles of IL-17A in heart failure.Therefore, we investigated whether common polymorphisms of genes IL17A and IL17RA (coding interleukin 17 receptor A) gene contribute to genetic predisposition to heart failure and adverse clinical outcomes associated with it .METHODS AND RESULTS:A total of 1713 adults patients with congestive heart failure and 1713 age-and sex-matched controls were genotyped for promoter SNPs, rs2275913 and rs8193037 in IL17A and rs4819554 in IL17RA, to assess the relationship between individual SNPs and the risk of congestive heart failure .Results showed that rs8193037 in IL17A was associated with the risk of congestive heart failure (P<0.01) after adjustment for multiple cardiovascular risk factors including age , sex, smoking status, diabetes, hypertension and dyslipidemia.This association was evident in both ischemic and non-ischemic heart failure (P<0.05).Furthermore, prospective fol-low-up of 12.7 months for the occurrence of adverse clinical outcomes showed that rs 4819554 in IL17RA was significantly associated with cardiovascular mortality (P<0.05) after adjustments for multiple cardiovascular risk factors and New York Heart Association functional class.CONCLUSION:This study demonstrated associations of rs8193037 in the promoter of IL17A with the risk of conges-tive heart failure, and of rs4819554 in the promoter of IL17RA with the risk of cardiovascular mortality in patients with congestive heart failure.These data lend further support to the notion that immune activation and genetic polymorphisms contribute to heart failure path -ogenesis and progression .

A sequential clean-up method was developed for the quantification of 10 plant growth regulators in bean sprout by the gas chromatography / mass spectrometry (GC / MS). The analytes were firstly extracted by the acided acetonitrile. Extraction was concentrated and re-dissovled by methanol. Then, it was divided to two aliquots. One of that was analyzed for 2,4-D-butyl ester and 2,4-D-ethyl ester after the purification by QuECHERS cartridge. Another one was treated by MCS solid phase extraction column including diverse eluting steps. After eluting by 5 mL methanol, composition 1 was obtain, concentrated, and methyl esterified by 10% boron trifluoride methanol solution. The treated extract was used for the determination of 4-chlorophenoxy acetic acid, β-naphthyl acetic acid, 2,4-dichlorophenoxy acetic acid, indole acetic acid and indole butyric acid. Composition 2 collected by eluting with 5 mL 5% amonium methanol was used for the determination of paclobutrazol, Kinetin, 6-Benzylaminopurine. The clean-up procedures are designed according to different chemistry properties of these plant growth regulators. The results showed that after spiking of 0. 01-0. 1 mg / kg selected plant growth regulators, average recovery ranged from 70. 0% to 93. 2%and relative standard deviation were 5. 2% -12. 3% . Limit of quantification (LOQ S / N≥10) and limit of detection (LOD S / N≥3) were 0. 01-0. 025 mg / kg and 0. 003-0. 008 mg / kg respectively. The developed purification method is easy, fast and accurate, and can be applied to routine test of plant growth regulators in bean sprout.

OBJECTIVETo investigate the role of c-Jun N-terminal kinase (JNK) signal transduction pathway in the rats of nonalcoholic fatty liver disease (NAFLD).

METHODSSixty four Sprague-Dawley rats were randomly divided into four groups: 8-week control group (NG8w), 12-week control group (NG12 w), 8-week high-fat diet (HG8w), and 12-week high-fat diet group (HG12w), with 16 rats in each group. Glucose infusion rate (GIR) was tested by euglycemic hyperinsulinemic clamp; aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride (TG), total cholesterol (TC), free fatty acid (FFAs), fast insulin (FIns), tumor necrosis factor alpha (TNF alpha), superoxide dismutase (SOD) and malondialdehyde (MDA) were tested by biochemistry automatic analyzer or RIA; The expression of JNK1, insulin receptor substrate-1 (IRS-1), phospho-IRS-1 Ser307 (p-IRS-1 Ser307), Protein kinase B (PKB) and phospho-PKB Ser473 (p- PKB Ser473) were detected by Western blot.

RESULTSCompared to control group, body weight, liver index, serum levels of ALT, AST, TG, TC, FIns, FFAs, TNF alpha, and TC, TG FFAs, MDA in liver homogenates were increased, while the level of SOD, and GIR were decreased. The expression of JNK1 protein and p-IRS-1 Ser307 in liver tissue was up-regulated, while expression of p-PKB Ser473 was decreased (P < 0.05). A positive correlation was found between the expression intensity of JNK1 and IR (Pearson correlation: 0.718, P < 0.01).

CONCLUSIONThe high-fat could induce the expression of JNK1, which in turn modulates the phosphorylation of proteins in the insulin signaling pathway, and induces insulin resistant.

OBJECTIVETo investigate the effect of early rehabilitation intervention on the incidences of extrauterine growth retardation (EUGR) and early diseases in preterm infants.

METHODSThe appropriate-for-gestational-age preterm infants with a gestational age of <34 weeks and a birth weight of 1 000 to <2 000 g who were admitted to the neonatal intensive care unit (NICU) within 24 hours after birth were enrolled in a prospective randomized controlled trial. These infants were randomly divided into rehabilitation intervention group and control group. The infants in the rehabilitation intervention group were given early rehabilitation after their vital signs became stable, including oral sensory and muscle strength training and pressure touching of the head, chest, abdomen, extremities, hands, and feet. The primary outcome measures were the time to independent oral feeding, length of hospital stay, and incidence rate of EUGR. The secondary outcome measures were the incidence rates of related diseases in preterm infants, such as apnea, feeding intolerance, and sepsis.

RESULTSA total of 97 preterm infants who met the inclusion criteria and had complete data were enrolled, with 48 in the control group and 49 in the rehabilitation intervention group. The rehabilitation intervention group had a shorter time to independent oral feeding than the control group (P<0.05). Compared with the control group, the rehabilitation intervention group had a shorter length of hospital stay and a lower corrected gestational age at discharge (P<0.05), as well as a lower incidence rate of EUGR (P<0.05). The rehabilitation intervention group ONCLUSIONS: Early rehabilitation intervention for preterm infants in the NICU may reduce the incidence rates of apnea, feeding intolerance, and EUGR and help them to achieve independent oral feeding early.
