Objective To analyze the impac factors of serum N?terminal pro?brain natriuretic peptide (NT?proBNP) in patients with renal failure in non?dialysis phase, and to determine the cut?off point of as a diagnostic values in these patients with heart failure (HF). Methods Cross?sectional study was applied. Clinical data of 145 patients (37 cases of CKD4, 89 cases of CKD5, and 19 cases of acute renal injury (AKI) with renal failure in non?dialysis phase were collected. Comparison between groups and lineal regression analysis were utilized to investigate the impact factors of NT?proBNP, and the receiver operating characteristic curve (ROC curve) to select a better cut?off point of diagnosis in these patients with HF. Results (1) Compared with patients without HF, patients with HF had significantly higher edema, cardiac troponin I, serum phosphorus concentration, and left atrial diameter (LA), while ALB and left ventricular ejection fraction (LVEF) were decreased (P<0.05). (2) The NT?proBNP was divided into 4 groups with four points: First groups of 36 cases, NT?proBNP 1 ?862 ng/L, second groups 37 cases, 866?2670 ng/L, third groups 37 cases, 2790?20 000 ng/L, fourth groups 35 cases, 20 900?35 000 ng/L. With the increase of NT?proBNP levels, the occurrence of AKI and CKD4 decreased gradually while the occurrence of CKD and edema were significantly increased (P<0.01). Systolic blood pressure, troponin I, uric acid, serum phosphorus, parathyroid hormone, 24 hours urine protein, LA, interventricular septum thickness (IVS), left ventricular posterior wall thickness (LVPW) level gradually increased. Hb, ALB, calcium, CO2, eGFR, LVEF significantly decreased (P<0.01). The serum NT?proBNP of patients with HF was significantly higher than that of patients without HF (19 150 ng/L vs 1530 ng/L, P<0.01). The serum NT?proBNP of patients with edema was significantly higher than that in patients without edema (5460 ng/L vs 1630 ng/L, P<0.01). (3) Single factor linear regression analysis indicated that higher NT?proBNP was positive correlated with HF, edema, cardiac troponin I, uric acid, serum phosphorus, LA, IVS and LVPW (P<0.05), while negative correlated with Hb, eGFR, ALB, serum calcium, CO2, LVEF (P<0.05), and not correlated with eGFR, uric acid, serum calcium (P>0.05). (4) The best cut?off point of NT?proBNP predicting HF in patients with renal failure in non?dialysis phase was 3805 ng/L, AUC=0.848, 95%CI 0.786?0.910. Sensitivity was 82.4%, specificity 74.5%, positive predictive value 62.1%, negative predictive value 87.3%, positive likelihood ratio 3.2, negative likelihood ratio 0.24. Conclusions The level of NT?proBNP>20 000 ng/L is mainly found in end?stage renal disease patients with HF. HF is a main factor for the increase of NT?proBNP in patients with renal failure in non?dialysis phase. High phosphorus viremia, anemia, and hypoalbuminemia are closely related to NT?proBNP. Therefore NT?proBNP predicting HF should take into account the effects of these confounding factors in these patients.

Objective To evaluate the changes in mRNA expressions of Toll-like receptor 4 (TLR4) and its down-stream cytokines IL-1β,IL-6 and TNF-a in incisional tissues from a rat with postoperative pain.Methods Incisional pain was induced in 74 male adult SD rats weighing 200-250 g.Paw mechanical withdrawal threshold (PMWT) around the wound on the operated and nonoperated sides was measured at 1 day before operation and at 0.5,1,2,6 and 12 hours as well as 1,2,3,5 and 7 days after operation.Skin incisional tissues were removed for determination of mRNA expressions of TLR4,IL-1β,IL-6 and TNF-a using real-time quantitative PCR at 1 day before operation and at 2 and 8 hours as well as 1,2,3,5 and 7 days after operation.Results Compared with the baseline value before operation,PMWT on the operated side was significantly decreased at 0.5 hours-5 days after operation,mRNA expression of TLR4 around the wounds on the operated side was down-regulated at 2 hours after operation followed by a gradual increase,mRNA expressions of IL-1β,IL-6 and TNF-α on the operative side were up-regulated at 2 and 8 hours as well as 1,2,3 and 5 days after operation (P ＜ 0.05),but no significant changes were found in PMWT and mRNA expressions of TLR4,IL-1β,IL-6 and TNF-α on the non-operated side(P ＞ 0.05).PMWT on the operated side was lowest at 6 hours after operation followed by the gradual increase,mRNA expression of TLR4 on the operated side peaked at 2 days after operation,and mRNA expressions of IL-1β,IL-6 and TNF-a respectively peaked at 2 hours,1 day and 3 days after operation (P ＜ 0.05).mRNA expressions of TLR4,IL-1β,IL-6 and TNF-a were negatively correlated with PMWT on the operative side (r =-0.501,-0.743,-0.893,-0.657,P ＜ 0.05),and mRNA expressions of IL-1 β,IL-6 and TNF-a were positively correlated with the level of TLR4 mRNA(r=0.764,0.283,0.667,P＜0.05).Conclusion mRNA expressions of TLR4 and its down-stream cytokines IL-1 β,IL-6 and TNF-a in skin incisional tissues are up-regulated,which may be involved in the development and maintenance of postoperative pain.

_ Objective_ To explore the relationship between the waist circumference ( WC) level and the non-alcoholic fatty liver disease ( NAFLD) in the Kailuan Group population. Methods A total of 7 896 individuals were selected as observed subjects from the Kailuan Group in 2011-2012 health physical examination. A questionnaire survey, blood biochemical, and abdominal ultrasound examination were finished by trained medical staff. According to the WC measurement and its quartile in the health examination, the observed subjects were divided into four groups (first, second, third, and forth quartile groups). Multivariate logistic regression analysis was used to analyze the relationship between the WC level and the NAFLD. Results ( 1 ) The detection rate of NAFLD in central obesity groupwashigherthanthatinnon-obesitygroup(67.1% vs27.9%,P<0.01). AlongwithincreasingWClevelinthe 4 quartile groups, the incidences of NAFLD were progressively increased, being 7. 1%, 23. 4%, 33. 4%, and 36. 1%, respectively. In the total population, the detection rates were 18. 8%, 42. 5%, 62. 0%, and 76. 1% in males;5. 4%, 24. 1%, 44. 7% and 62. 9% in females. (2)Multivariate logistic regression analysis showed that WC is an independent risk factor after adjusting age, gender, and other risk factors, the OR value being 1. 08. It was also noticed that compared with the first quartile group, the second, third, and forth quartile groups had increased risk of NAFLD after adjusting above factors in different genders, with the OR values being 2. 74, 6. 59, and 11. 15 in males, while 2. 61, 5. 03, and 3. 67 in females, respectively. Conclusion WC was an independent risk factor for NAFLD;the incidence of NAFLD increased with increasing WC level in the Kailuan Group population.

To investigate the effects of Losartan,an angiotensinⅡ(AngⅡ)receptor(AT_1) antagonist,on pancreatic stellate cells(PSCs)and its possible mechanisms.Methods (1)PSCs were isolated from pancreatic cancerous samples to test the expressions of AT_1 and collagenⅠafter incubated with AngⅡor/and Losartan.(2)Ninety S-D rats were divided into normal group,control group and treatment group,with 30 rats in each.The rats in control and treatment groups were induced pancreatic fibrosis by injection of 2% trinitrobenenze sulfonic acid(TNBS)into biliopancreatic duct.Rats in treat- ment group were then treated with Losartan by garage daily and rats in control group were only given distilled water.The rats were sacrificed on day 3,7,14,21 and 28,respectively,and pancreas were removed.The histological abnormalities were observed by electron microscope.The mRNAs of trans- forming growth factor?_1(TGF?_1)and procollagenⅠwere detected by reverse transcription-polymerase chain reaction(RT-PCR).The expression of TGF?_1 and?-smooth muscle actin(?-SMA)proteins was assessed by immunohistochemistry and the level of?-SMA protein was quantified by Western blot. Results In vitro,there existed AT_1 expression in PSCs,and Losartan reduced expression of collagenⅠ.Losartan treatment reversed the histological abnormalities observed by electron microscope,com- pared to treatment with distill water.The expression of?-SMA,TGF?_1 and procollagenⅠwere signifi- cantly higher in the control group than those in normal group and were reduced by Losartan to different extent in treatment group.Conclusion AT_1 antagonist can inhibit the activation and the profibrogenic action of PSCs by blocking AT_1 receptor-mediated pathways.
