Objective To investigate the predictive value of fluid overload for mortality in children with severe sepsis.Methods In this retrospective study,the children with severe sepsis who were admitted to the Pediatric Intensive Care Unit (PICU),Children's Hospital of Soochow University between January 2011 and March 2015.Fluid accumulation was calculated in the first 72 hours after admission.Pediatric index of mortality Ⅱ (PIM2) score was calculated during the first 1 hour after admission.Multivariate Logistic regression analysis assessed the relationship between fluid overload and mortality after adjustment for confounding factors.The predictive value of fluid overload for mortality was assessed by the receiver operating characteristic curve and au area under the receiver-operating-characteristic curve (AUC).Results Of the 199 children admitted,62 cases (31.2％) died during PICU stay.Among the children,133 cases (66.8％) had fluid overload of＜5％,55 cases (27.6％)had fluid overload of≥5％-10％,and 11 cases (5.6％) had fluid overload of≥ 10％.Multivariate regression analysis showed that a high fluid overload percent (OR =1.263,95 ％ CI:1.113-1.434,P ＜ 0.001),a high PIM2 score (OR =1.028,95 ％ CI:1.012-1.043,P ＜ 0.001) and multiple organ dysfunction syndrome(OR =4.160,95％ CI:1.728-10.012,P =0.001) were independent risk factors for mortality in children with severe sepsis.The fluid overload was significantly associated with mortality (OR =1.309,95％ CI:1.158-1.480,P ＜0.001),even after adjustment for age and illness severity assessed by PIM2 scores.Fluid overload achieved AUC of 0.741 (95％ CI:0.661-0.820,P ＜ 0.001) for predicting mortality in children with severe sepsis.Conclusion Fluid overload developed during the first 72 hours after admission is independently associated with and predictive of PICU mortality in children with severe sepsis.

Objective To investigate the clinical application of serum interleukin-6 (IL-6)and interleukin-22 (IL-22) levels in predicting the recurrence of hepatitis B virus (HBV)-related early hepatocellular carcinoma (HCC) after receiving microwave ablation (MWA).Methods Preoperative peripheral blood samples were collected in 49 patients with early-stage HBV-related HCC,and serum concentrations of IL-6 and IL-22 were measured by using ELISA.Thirty healthy volunteers were recruited and used as the control group.The xtile software was used to define the best cut-off value,and the IL-6 and IL-22 levels were divided into highlevel group and low-level group.The tumor-free survivals of high-level and low-level groups were analyzed with Kaplan-Meier analysis,log rank test was adopted to determine the difference,and Cox regression model was employed to screen the risk factors affecting HBV-related HCC recurrence.Results The serum IL-6 and IL-22 levels of HCC group were 13.20 pg/ml (11.87-15.79 pg/ml) and 42.18 pg/ml (34.39-57.44 pg/ml) respectively,which were significantly higher than 10.47 pg/ml (9.50-13.82 pg/ml) and 25.45 pg/ml (22.31-30.12 pg/ml) of the control group (P=0.001 and P＜0.001 respectively).Kaplan-Meier analysis revealed that preoperative lower IL-6,higher total bilirubin and lower albumin levels indicated a shorter disease-free survival (DFS),and IL-22 levels had no statistically significant effect on the recurrence of HCC.Cox regression multivariate analysis showed that lower serum IL-6 level (≤ 13.2 pg/ml;hazard ratio=3.721;95％ CI=1.674-8.272;P=0.001) and lower serum albumin level (≤41.0 g/L;hazard mtio=2.085;95％CI=1.101-3.950;P=0.024) were independent risk factors affecting HBV-related HCC recurrence Conclusion Preoperative serum IL-6 level and serum albumin level can be used as the predictors of HCC recurrence in patients with HBV-related early HCC who are receiving MWA treatment.(J Intervent Radiol,2017,26:232-236)

Objective To observe the effect of tumor necrosis factor-α( TNF-α) on islet cell apoptosis and TXNIP expression.Methods INS-1 cells were cultured in vitro, treating with TNF-α(0, 1, 5, 10 and 20 mg/L).We tested the effect of TNF-αon cell viability by CCK-8.INS-1 cells were treated with TNF-α( 5 mg/L, 24 h) for the proper concentration and incubation time; mRNA expression of TXNIP and ChREBP were measured by real-time PCR;in addition, protein levels of TXNIP , ChREBP and FOXO1 were analyzed by Western blot .Results TNF-αdecreased the survival rate of INS-1 cells in a dose-dependent manner ( P<0.05 ) , and induced apoptosis;protein and mRNA expression of TXNIP and ChREBP were significantly higher than that in control group ( P<0.05 );while the expression of protein level of FOXO 1 was down-regulated .Conclusions TNF-αinduces apoptosis in INS-1 cells and aggravates the cells damage .

AIM AND METHODSThe effects of losartan (after operation 2 week to 10 week, 5 mg/kg d ig) on generation of AT1R-AA in sera were observed during development of hypertension in rats. The renovascular hypertension (RVH) model was established by two-kidney one-clip method, a synthetic peptide corresponding to amino acid sequence 165-191 of the second extracellular loop of the angiotensin II-1 receptor (AT1R) was used as antigen, SA-ELISA were used to examine sera AT1R autoantibody (AT1R-AA).

RESULTSThe frequencies and titres of AT1R-AA after operation one week rats were significantly increased (P < 0.05). The treatment with losartan not only inhibited structural and functional changes, but also the frequencies and titres of AT1R-AA was significantly lower (P < 0.05) than RVH group.

CONCLUSIONIt is suggested that the losartan significantly inhibits generation of the AT1R-AA.

The aim of this study was to observe the change in angiotensin II receptor subtype 1 (AT(1)) autoantibody during the development of renovascular hypertension (RVH). The Goldblatt renovascular hypertension model was established by the two-kidney one-clip method, and a synthetic peptide corresponding to amino acid sequence 165-191 of the second extracellular loop of the AT(1)-receptor was used as the antigen. Sera AT(1)-receptor autoantibody was detected by SA-ELISA. It was shown that two weeks after operation both the frequency of occurrence and the titre of autoantibodies to AT(1)-receptor were significantly increased as compared with the pre-treatment control. The increase in autoantibodies lasted several weeks and then decreased gradually to the pre-clipping level at 12 weeks. It is suggested that autoimmune mechanisms are involved in the pathogenesis of renovascular hypertension and the AT(1) autoantibodies may be one of the mechanisms leading to cardiac hypertrophy.

BACKGROUNDFood composition and style is changing dramatically now, which causes inappropriate secretion of hormones from brain, gastrointestinal and endo-pancreas, may be related to unbalance of glucose in blood. The aim of this study was to explore the fast response of C-peptide, glucagon-like peptide-1 (GLP-1), ghrelin and endomorphin-1 (EM-1) to the eastern and western style meals in patients with type 2 diabetes mellitus.

METHODSThe study enrolled 57 patients with type 2 diabetes (20 men and 37 women, mean age (67.05 ± 8.26) years). Eastern style meal (meal A) and western style meal (meal B) were designed to produce the fullness effect. C-peptide, GLP-1, ghrelin and EM-1 were assessed before (0 hour) and after (2 hours) each diet.

RESULTSThe delta (2h - 0h) of C- peptide in meal A was significantly lower than that in meal B (P = 0.0004). C-peptide, GLP-1, ghrelin and EM-1 were obviously higher before meal B than those before meal A (P < 0.0001, < 0.0001, = 0.001, = 0.0004 respectively). Blood glucose 2 hours and 3 hours after meal B were higher than those after meal A (P = 0.0005, 0.0079 respectively). Correlations between GLP-1 and ghrelin were strongly positive before both meals and 2 hours after both meals and also in relation to the delta of meal A and meal B (r(A0h) = 0.7836, r(B0h) = 0.9368, r(A2h) = 0.7615, r(B2h) = 0.9409, r(A(2h-0h)) = 0.7531, r((2h-0h))B = 0.9980, respectively, P < 0.0001).

CONCLUSIONWestern style meal (high fat and protein food) could make more response of C-peptide than eastern style meal, and could stimulate more gut hormones (GLP-1, ghrelin) and brain peptide (EM-1) at the first phase of digestion.

The aim of the present study is to investigate the change of thioredoxin (Trx) system in myocardial tissue of type 2 diabetic rats after myocardial injury and the underlying mechanism. Adult Sprague Dawley rats were randomly divided into two groups: normal control (NC) group and diabetes (DM) group. Rats in DM group were subjected to high-sugar, high-fat diet and streptozotocin (STZ) injection. Rats in NC group were only given normal diet and equal amount of citric acid buffer injection. At week 1, 2, 4, 12, 21 after STZ injection, plasma glucose concentration and the concentrations of insulin, creatine kinase MB (CK-MB), cardiac troponin I (cTnI) in serum were measured. Myocardial Trx and thioredoxin reductase (TR) activities, as well as caspase-3 activity, were determined by respective assay methods. Protein and mRNA levels of Trx, TR, Trx interacting protein (TXNIP) were determined by Western blot and real time PCR, respectively. The results showed that type 2 diabetic rat model was successfully established at week 1 after STZ injection, and myocardial injury was induced from week 2. Moreover, caspase-3 activity was significantly increased at week 4, 12 in diabetic rats. The activities of myocardial Trx and TR in diabetic rats was decreased from week 2, and continually aggravated as the disease developed. Compared with those in NC group, the mRNA levels of Trx1, Trx2, TR1, TR2 in DM group decreased at week 4, and then increased in week 12. In DM group, the protein levels of Trx1, Trx2, TR1 and TR2 increased significantly at week 12. The mRNA expressions of myocardial TXNIP in diabetic rats were significantly increased at week 4, 12, 24 and protein expression was increased at week 12. These results suggest diabetes can decrease myocardial Trx, TR activity, inducing myocardial cell apoptosis and heart injury. The inhibitory effect of diabetes is mainly associated with TXNIP up-regulation and Trx nitration.

The purpose of this study was to compare the vasodilating effects of angiotensin-(1-7) [Ang-(1-7)] on the different vessels and to clarify its mechanisms by using relaxing responses of preconstricted vascular rings. The results showed: (1) Ang-(1-7) dose-dependently induced vasorelaxation in all the vessels studied. However, there is apparent heterogeneity in the responsiveness of vessels from different origin. (2) The Ang-(1-7)-induced vasorelaxation was endothelium dependent and largely mediated by NO system. (3) The vasodilator action of Ang-(1-7) was not mediated by AT1 or AT2 receptor subtypes. It is suggested that the Ang-(1-7)-induced vasorelaxation is endothelium dependent by some other unclarified angiotensin receptor subtypes and is largely mediated by NO system.

In this report, we present two cases of bronchial foreign body granulomas caused by the suture ties used in bronchial surgery for esophageal cancer. Both of them was hospitalized as "tumor transfer or an invasion", but pathological examination of the neoplasms indicated an inflammatory granuloma showing reaction to the foreign body. These two cases give us an attention that the neoplasms in tracheal or bronchial was not only the invasion or transfer of the primary tumor, but also the possibility of granuloma development due to the surgical sutures.

Using two-kidney one-clip renal hypertensive (2K1C group), stress-induced hypertensive (neural group), DOCA-salt treated hypertensive (DOCA group) and spontaneously hypertensive rats (SHR group), to investigate the change in AT(1A)-receptor autoantibodies (AT(1A)-AAs) during the development of the four types of hypertension. The biological activities of AT(1A)-AAs were examined. It was shown that the frequency of occurrence and titres of AT(1A)-AAs increased significantly during the development of hypertension. In the four hypertensive groups studied, the occurrence of AT(1A)-AAs was most prominent in SHR, 2K1C and neural groups. The biological effects of AT(1A)-AAs were shown to increase the beating frequency of cultured neonatal myocardial and vascular contractile tension. It is suggested that autoimmune mechanisms are involved the pathogenesis of different types of hypertension and the AT(1A)-AAs may be one of the mechanisms leading to cardiac hypertrophy.
