Objective To evaluate the predictive value of serum cystatin C (sCys C),urinary neutrophil gelatinase associated lipocalin(uNGAL) and interleukin-18 (uIL-18)in early diagnosis of continuous renal replacement therapy (CRRT) in systemic inflammatory response syndrome (Sepsis) complicated with acute kidney injury (AKI) and difference post-replacement volume in CRRT.Methods Total of 71 patients admitted to the intensive care unit during from July 2012 to April 2016 were included in the current prospective study.The patients were assigned into the CRRT and non-CRRT groups based on whether the patients were accepted the CRRT.sCys C,uNGAL,uIL-18,serum creatine,blood urea nitrogen and leukocyte were measured on the day of admission.We collected blood and urinary samples at different time points (12h,24h)in order to measure sCys C,uNGAL,uIL-18 when the patients accepted difference post-replacement volume(2L/h and 4L/h) in CRRT.Multivariate logistic regression analysis was used to determine whether sCysC,uNGAL and uIL-18 levels were independent predictors of Sepsis complicated with AKI.A receiver operating characteristic (ROC) curve was constructed and the area under the ROC curve(AUC) was calculated to assess the predictive strength of sCys C,hNGAL and uIL-18.Results Compared to the Non-CRRT subjects,the age,the gender,Scr,BUN,WBC in the subjects of the CRRT group were of no significant diffience,but the levels of sCys C,uNGAL and uIL-18 were significantly higher(P ＜ 0.05).sCys C,uNGAL and uIL-18 achieved the AUC of 0.905(95％CI:0.831-0.979,P=0.000),0.926(95％CI:0.862-0.991,P=0.000),0.897(95％CI:0.827 -0.967,P =0.000),respectively,for predicting the development of Sepsis complicated with AKI.No significant differences were noted between 2L/h group with 4L/h group at the beginning of CRRT.The levels of sCys C,uNGAL and uIL-18 decreased significantly in 2L/h and 4L/h groups at different time points (12h,24h) during CRRT.The levels of sCys C,uNGAL and uIL-18 in 4L/h group had decreased more significantly than 2L/h group at the 24h time point.Conclusion The authors consider that sCys C,uNGAL and uIL-18 are both independent predictors of Sepsis complicated with AKI in CRRT.uNGAL has a better predictive value in early prediction of Sepsis complicated with AKI in CRRT.There was more significant treatment effect in the post-replacement volume of 4L/h after 24h treatment in CRRT.

Objective To study the effect of euthyrox on blood lipids in patients with hypothyroidism throngh the meta analysis.Methods Patients with clinical hypothyroidism theated by euthyrox on blood lipid effect of randomized controlled trials were retried by Pubmed(2000/2014-07),EMbase (2000/2014-07),the Cochrane library(2014,7),the Chinese biomedical literature database(2000/2014-07),retrieved the time limit from January 2000 to July 2014.The paper were objective evaluated of the quality,Meta analysis with Rev Man 5.3 software system applicated by Cochrane collaboration.Results Euthyrox could significantly reduce cholesterol levels of hypothyroidism patients ,it was statistically significant difference(OR=0.63,95%CI:0.71 ~0.55,P<0.001);Euthyrox could significantly reduce triglyceride levels of hypothyroidism patients,difference was statistically significant(OR =0.29,95%CI:0.34 ~0.25,P <0.001 );Euthyrox could significantly reduce low-density lipoprotein cholesterol levels of hypothyroidism patients,it was statistically significant difference(OR=0.22,95%CI:0.30 ~0.14,P<0.001);euthyrox could obviously increase high-density lipoprotein cholesterol levels, it was statistically significant difference (OR =0.21, 95% CI:0.17 ~0.26, P <0.001 ). Conclusion Euthyrox could significantly reduce total cholesterol,triglyceride,low-density lipoprotein cholesterol(hdl-c)of hypothyroidism patients,and promote the synthesis of high-density lipoprotein cholesterol(hdl-c),could effectively promote the lipid metabolism,reduce blood fat level,prevent the happening of the disease of heart head blood-vessel hypothyroidism patients,have the guide meaning to clinical treatment.

ObjectiveTo explore the clinical significance of heart-type fatty acid-binding protein (H-FABP) in acute myocardial infarction(AMI) patients. MethodsThe level of H-FABP was assayed within 30 min, 1 h, 2 h, 4 h,6 h and 12 h by enzyme linked immunosorbent assay (ELISA) in 46 AMI patients, and cardiac troponin Ⅰ(cTnⅠ) and creatinine kinase(CK-MB) also was assayed by routine method.The diagnostic accuracy was compared among different methods. ResultsThe diagnostic accuracy of H-FABP[95.7％ (44/46)] was significantly higher than cTnⅠ[65.2％(30/46)] and CK-MB[41.3％ (19/46)](P ＜0.05). The levels of H-FABP, cTnⅠ and CK-MB significantly increased after AMI onset 4,6,12 hrespectively. ConclusionThe diagnosticaccuracy of H-FABP is higher and can be used as a parameter for the early diagnosis of AMI.

Objective To compare target dosimetric distribution and normal tissue radiation between different static intensity?modulated radiation therapy ( IMRT) plans and volumetric modulated arc therapy ( VMAT) and to identify the best IMRT plan for patients with primary mediastinal B?cell lymphoma ( PMBCL) . Methods A total of 16 patients ( 8 males and 8 females) with early?stage ( Ann?Arbor stageⅠ) PMBCL were enrolled in this study,with doses of 45 Gy for primary gross tumor volume ( PGTV) and 40 Gy for planning target volume (PTV).Four plans were designed for each patient,consisting of static IMRT (5F?IMRT,7F?IMRT,9F?IMRT) and VMAT,and the target dosimetric distribution,normal tissue radiation dose,and efficiency of each plan were evaluated. The difference of dose was analyzed by analysis of variance. Results The mean conformity index ( CI) and homogeneity index ( HI) for PGTV in 5F?,7F?,9F?IMRT and VMAT were 1. 01 and 1. 10, 1. 01 and 1. 10, 1. 01 and 1. 10, and 1. 01 and 1. 11 ( P= 0. 963 and 0. 843) ,respectively,while these two indices for PTV were 1. 04 and 1. 22,1. 03 and 1. 19,1. 03 and 1. 17, and 1. 08 and 1. 14( P=0. 964 and 0. 969) ,respectively. The parameters of volume and dose were similar on normal tissue ( P= 0. 192?1. 000 ) . The treatment time and number of monitor units in 9F?IMRT were significantly higher than those in other static IMRT plans and VMAT ( P=0. 000,0. 000) ,and among these plans,VMAT had the lowest number of monitor units ( 13 345. 0 MU) and the shortest treatment time ( 5. 9 min) . Conclusions The target volume coverage of 7F?and 9F?IMRT is better than that of 5F?IMRT and VMAT.For early?stage PMBCL,VMAT is not superior to IMRT in terms of dosimetry,especially with a larger area of low?dose radiation to the breast,but it is highly efficient in practice.

OBJECTIVE: To study the effect of silencing LncRNA SNHG7 on hypoxia/reoxygenation (H/R)-induced cardiomyocyte injury and its targeted regulation on miR-181b-5p. METHODS: Rat cardiomyocytes H9c2 were cultured in vitro and randomly divided into control group, H/R group, H/R + si-NC group, H/R + si-SNHG7 group, H/R + si-SNHG7 + anti-miR-NC group and H/R + si-SNHG7 + anti-miR-181b-5p group. The content of lactate dehydrogenase (LDH), malondialedhyde (MDA) and the activity of superoxide dismutase (SOD) were detected. Flow cytometry was carried out to detect the rate of apoptosis. qRT-PCR was used to detect the expression of SNHG7 and miR-181b-5p. Dual luciferase report experiment was used to verify the targeting relationship between SNHG7 and miR-181b-5p. Western blotting was used to detect the expression of Bax and Bcl-2. RESULTS: Compared with the control group, the H/R group showed significantly increased SNHG7 expression in cardiomyocytes, reduced miR-181b-5p expression, higher levels of LDH and MDA, reduced activity of SOD, increased cell apoptosis rate, higher level of Bax protein, and reduced level of Bcl-2 protein (all P< 0.05). Compared with the H/R and H/R + si-NC groups, the H/R + si-SNHG7 group had significantly reduced level of LDH and MDA, increased activity of SOD, reduced apoptosis rate, reduced level of Bax protein, increased level of Bcl-2 protein (all P< 0.05). The dual luciferase report experiment confirmed that SNHG7 could target miR-181b-5p. Interference with the expression of miR-181b-5p could reduce the effect of silencing SNHG7 on H/R-induced cardiomyocyte oxidative stress and apoptosis. CONCLUSION Silencing SNHG7 may inhibit H/R-induced cardiomyocyte oxidative stress and apoptosis by up-regulating the expression of miR-181b-5p, thereby exerting a protective effect on cardiomyocytes.
