Objective To observe the relationship between serum level of H-FABP before percutaneous coronary intervention (PCI) and prognosis in patients with ST-segment elevation myocardial infarction (STEMI). Methods A total of 104 cases were recruited in this study. PCI was performed 12 h after onset. The concentration of H-FABP was detected before operation. Gensini score system was used to calculate the integral of all patients after coronary angiography. According to Gensini score, patients were divided into three groups, 34 cases in group A (8≤Gensini scores<41), 34 cases in group B (41≤Gensini scores<64) and 36 cases in group C (Gensini scores≥64). Indicators were analyzed statistically including systolic blood pressure (SBP), diastolic blood pressure (DBP), smoking history, H-FABP, left ventricular ejection fraction (LVEF), total cholesterol (TC), triglycerides (TG), high density lipoprotein (HDL-C), low density lipoprotein (LDL-C), fasting blood sugar, diabetes (DM) and hypertension. The patients were followed up for 12 months after operation. According to the occurrence of major adverse cardiovascular events (MACE), patients were divided into MACE group and non-MACE group. The related factors of two groups were statistically analyzed. The multivariate Logistic regression analysis was used to screen the risk factors of MACE for patients with STEMI after emergency PCI. Results There is a gradually increasing tendency in total cholesterol levels among three A, B and C groups (P<0.05). LVEF values were lower in B group and C group than that of A group (P<0.05). There were no significant differences in levels of SBP, DBP, H-FABP, TG, HDL-C, LDL-C, fasting plasma glucose and smoking history, DM, and hypertension between three groups (P>0.05). In 12-month follow-up, the proportion of STEM combined with DM, the time from onset to PCI, the level of TC, the level of H-FABP before operation and Gensini score were significantly higher in MACE group than those of non-MACE group (P<0.05). Logistic regression analysis showed that STEM combined with DM, higher serum level of H-FABP before operation were risk factors of MACE in 12-month after operation (P<0.05). Conclusion For patients with acute STEM combined with diabetes and elevated preoperative serum level of H-FABP, be alert to the occurrence of MACE in 12-month after PCI.

OBJECTIVETo observe the effect of garlicin on adhension molecules CD11a and deformability of peripheral neutrophil in patients with acute cerebral infarction (ACI).

METHODSNeutrophils were separated from peripheral blood of healthy subjects and ACI patients, and incubated in 37 degrees C in vitro. The CD11a expression was detected by antibody fluorescence labeling method and the time of neutrophils passing millipore membrane were measured for calculation of the filter index.

RESULTSCD11a expression rate in healthy subjects was 34.64 +/- 25.34%, while in patients was 55.35 +/- 30.54%, difference between them was significant (P < 0.05). After garlicin treatment, it lowered to 49.16 +/- 31.68%, as compared with untreated group, P < 0.05. The neutrophil filter index in healthy group, untreated group, garlicin treated group and Nimodipine treated group was 0.87 +/- 0.46, 6.42 +/- 6.40, 3.47 +/- 3.67 and 5.03 +/- 3.72 respectively, comparison between that in the garlicin treated group and in untreated group showed significant difference (P < 0.05).

CONCLUSIONGarlicin could effectively inhibit the CD11a expression in peripheral blood neutrophils and improve the deformability of the neutrophils in ACI patients.

Objective The present study aims to investigate the effect of the early nasal jejunum nutrition (NJN) on the inflammatory markers of severe acute pancreatitis (SAP) and to research if the NJN improves the recovery of SAP. Method SAP inpatients were observed during 2016. One group who accepted the NJN was experimental group and another group who did not accept the NJN was control group.The difference of serum albumin (ALB), procalcitonin (PCT), C reactive was compared to observe the effect of the early nasal jejunum nutrition (NJN) on the inflammatory markers of severe Acute Pancreatitis protein (CRP), interleukin 6 (IL-6) and serum amylase (AMY) between the highest and lowest levels in two group respectively and the time of diet recovery between two groups. Results (1) The difference of interleukin 6 (IL-6) between the highest and lowest levels in experimental group was significantly smaller than that of the control group;the difference of ALB, CRP and PCT between the highest and lowest levels in experimental group was not different from the control group;2) The time of diet recovery of experimental group was shorter than that of the control group. Conclusion The early NJN can reduce the IL-6 level and the time of diet recovery,and then,improve the SAP recovery.

The objective of current study was to investigate the quasispecies of hepatitis E virus in swine. The partial ORF2 region of HEV envelope gene from four swine HEV strains was amplified by RT-nested polymerase chain reaction (RT-nPCR). After cloning and transformation of PCR products, 20 positive clones of each HEV isolate were subject to sequencing and DNA analysis. The homology among the different clones of each isolates was 96.8%-99.7%, 98.8%-99.7%, 98.8%-99.7% and 100%, respectively, while there was 96.8%-100% sequence identity at the nucleotide level compared with HEV strains isolated in Shanghai (SAAS-JDY5). This study confirmed that there existed quasispecies of HEV in swine.

OBJECTIVETo investigate the current status of exclusive breastfeeding for the second child in the context of the universal two-child policy and the factors influencing exclusive breastfeeding.

METHODSA self-designed questionnaire for the current status of breastfeeding and related factors influencing breastfeeding for the second child were used to survey 836 mothers with a second child, who were selected by cluster sampling, in Quzhou, Zhejiang, China.

RESULTSA total of 680 usable questionnaires were obtained. The rate of exclusive breastfeeding for the second child was significantly lower than for the first child (34.9% vs 42.2%; P<0.05). The univariate analysis revealed that there were significant differences between the exclusive and non-exclusive breastfeeding groups in the mother′s age, education background, occupation and time of maternity leave, mode of delivery of the first child, sex of the first child, feeding pattern of the first child, mode of delivery of the second child, whether the second child was admitted to the intensive care unit, whether the father supported breastfeeding, and whether the grandmother/maternal grandmother supported breastfeeding (P<0.05). The multivariate logistic regression analysis showed that artificial feeding+partial breastfeeding for the first child (OR=12.286, P<0.05), cesarean section for the second child (OR=1.724, P<0.05), and having no breastfeeding support from the maternal grandmother (OR=1.651, P<0.05) were main factors for influencing exclusive breastfeeding.

CONCLUSIONSThe current status of exclusive breastfeeding for the second child is not optimistic in the context of the universal two-child policy. Education about breastfeeding should be taken seriously at the birth of the first child, the rate of cesarean section should be reduced, and the family members should support exclusive breastfeeding, in order to improve the status of exclusive breastfeeding.

OBJECTIVETo study the effects of the change in transient receptor potential vanilloid 1 (TRPV1) channel activity on the degree of airway inflammation in asthmatic mice.

METHODSBALB/c mice were randomly divided into control, asthma, capsaicin (TRPV1 agonist), capsazepine (TRPV1 antagonist), and dexamethasone groups. The asthmatic mouse model was established by intraperitoneal injection of mixed ovalbumin-aluminium hydroxide solution and ultrasonic atomization with OVA for sensitization and challenge. The capsaicin, capsazepine, and dexamethasone groups were given intraperitoneal injection of capsaicin (30 μg/kg), capsazepine (10 μmol/kg), and dexamethasone (2 mg/kg) respectively, at 30 minutes before challenge. Hematoxylin and eosin staining was used to observe the degree of pulmonary inflammation. ELISA was used to measure the content of interleukin-8 (IL-8) and interleukin-13 (IL-13) in bronchoalveolar lavage fluid (BALF). Real-Time PCR was used to measure the relative content of TRPV1 mRNA in lung tissue.

RESULTSCompared with the asthma group, the capsazepine and dexamethasone groups showed reduced pulmonary inflammation, while the capsaicin group showed aggravated pulmonary inflammation. Compared with the control group, the asthma and capsaicin groups showed increases in the content of IL-13 and IL-8 in BALF and the mRNA expression of TRPV1 in lung tissue (P<0.05). Compared with the asthma group, the capsazepine and dexamethasone groups showed reductions in the content of IL-13 and IL-8 in BALF and the mRNA expression of TRPV1 in lung tissue (P<0.05). The capsaicin group showed increases in the content of IL-13 and IL-8 in BALF (P<0.05).

CONCLUSIONSTRPV1 channel agonist and antagonist can influence the degree of airway inflammation in asthmatic mice. Dexamethasone may reduce airway inflammation through regulating TRPV1 level.

BACKGROUNDPrevious studies have demonstrated that serum uric acid (UA) is an independent predictor of incident type 2 diabetes mellitus (T2DM) in general populations. This study aimed to investigate specific characteristics of UA and its relationship between UA and blood glucose and other risk factors in the Chinese population.

METHODSA total of 946 subjects were included in this study. UA, glucose, insulin, fractional excretion of UA (FEua), creatinine clearance rate (Ccr), hemoglobin A1c (HbA1c), fructosamine (FA), blood pressure and lipids were studied and also reexamined after the patients underwent two weeks of combined therapeutics.

RESULTSUA levels were the highest in subjects with impaired glucose regulation (IGR), followed by subjects with normoglycemia (NGT) and finally by subjects with T2DM. The level of the 2-hour postprandial insulin and the area under the curve for insulin (AUCins) showed a similar tendency. The UA levels initially increased with increasing fasting blood glucose (FBG) and postprandial blood glucose (PPBG) levels, up to 7 mmol/L and 10 mmol/L, respectively, and thereafter decreased at higher FBG and PPBG levels. Compared with subjects in the lower serum UA quartile, subjects in the upper quartile of serum UA levels had higher weights, triglyceride levels, and creatinine levels as well as lower Ccr and FEua levels. Compared with women's group, UA levels were higher, and FEua levels were lower in men's group. Sex, body mass index (BMI), mean arterial blood pressure (MAP), serum triglycerides (TG), FA and Ccr were independent correlation factors of UA. UA decreased and FEua increased after the patients underwent a combined treatment.

CONCLUSIONSUA increased initially and then decreased as glucose levels increased from NGT to IGR and T2DM. Compared with NGT and T2DM, IGR subjects had higher SUA levels, which related to its high levels of insulin. Under T2DM, male gender, BMI, MAP, Ccr, TG and FA are independent correlation factors of UA. Glucose-lowering, antihypertensive, lipemia-regulating combined treatments were of advantage to decline of SUA of T2DM.

AIM: To observe the effect of endothelin-1(ET-1) on the cytoskeleton protein F-actin of cultured human trabecular meshwork (HTM) cells. METHODS: Cultured HTM cells were randomly divided into four groups: control group(0mol/L), low-dose ET-1(10-9mol/L) treatment group, middle-dose ET-1(10-8 mol/L) treatment group, and high-dose ET-1(10-7 mol/L) treatment group. After treated with ET-1, the expression of cytoskeleton protein F-actin in trabecular meshwork was analyzed with Western-blot and the distribution of F-actin was detected with FITC-Phalloidin probe. RESULTS: ET-1 dose-dependently and significantly increased F-actin in trabecular meshwork cells. The F-actin stress fiber and periphery actin fiber highly increased and manifested mild reorganization after treated with ET-1; and there were much more cell-to-cell and cell-to-extracellular matrix attachments formation in ET-1 treated HTM cells than that in the untreated HTM cells. CONCLUSION: ET-1 promoted the expression of cytoskeleton protein F-actin and induced the trabecular meshwork actin cytoskeleton reorganization.
