ObjectiveTo investigate the effect on improving immune function by hemofiltration combined with hemoabsorption in septic patients with low human leukocyte antigen DR (HLA-DR) expression.Methods A prospective randomized controlled trial was conducted. Sixty sepsis patients aged over 18 years, with HLA-DR expression lower than 30% were enrolled, and they were randomly divided into experimental group and control group, n = 30 in each group. The patients were treated with standard operating procedure for sepsis, and hemofiltration combined with hemoabsorption were added in addition in the experimental group within 1-3 days. The continuous veno-venous hemofiltration (CVVH) mode was performed, with former dilution volume 4 L/h, and the hemofilter HF2000 was carried out with blood absorber HA-330H. The expression of HLA-DR in peripheral blood mononuclear cells was determined before the treatment and 3, 5, 7 days after treatment. Acute physiology and chronic health evaluationⅡ(APACHEⅡ) score, duration of mechanical ventilation, length of intensive care unit (ICU) stay, and 28-day survival rate were evaluated in both groups.Results The HLA-DR expression before treatment in experimental group and control group was both lower than 30%, and there was no statistical difference [(25.9±7.3)% vs. (26.4±6.7)%,P>0.05]. The HLA-DR expression at 3, 5, 7 days after treatment in experimental group was gradually increased, and it was significantly higher than that of the control group [3 days: (38.9±8.6)% vs. (29.3±7.1)%, 5 days: (42.7±9.2)%vs. (31.4±6.5)%, 7 days: (40.9±8.5)% vs. (29.4±6.7)%, allP< 0.05]. There was no significant difference in APACHEⅡ score before treatment between experimental group and control group (22.4±5.3 vs. 21.7±6.2,P>0.05). APACHEⅡ score at 3, 5, and 7 days after treatment was gradually decreased in experimental group, and it was obviously lower than that of the control group (3 days: 18.6±3.6 vs. 20.5±4.3, 5 days: 15.8±3.9 vs. 21.1±4.4, 7 days: 14.9±4.2 vs. 19.8±3.7, allP< 0.05). Compared with the control group, the duration of mechanical ventilation (days: 13.3±3.4 vs. 19.8±3.7,t = 6.432,P = 0.003) and length of ICU stay (days: 20.7±3.9 vs. 26.8±4.7,t = 5.452, P = 0.006) in experimental group were significantly shortened, and the 28-day survival rate was significantly elevated (83.3% vs. 73.3%,χ2 = 3.121,P = 0.016).Conclusion Hemofiltration combined with hemoabsorption can improve the expression of HLA-DR in sepsis patients with low expression of HLA-DR, and it can improve immune function and prognosis of sepsis patients in certain degree.

Objective To evaluate whether an early change in 18F-fluorodeoxyglucose (18F-FDG) uptake can predict tumor response to epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) and prognosis in patients with non-small cell lung cancer (NSCLC). Methods From August 2009 to April 2015, 22 patients with NSCLC who were eligible to EGFR-TKI treatment were enrolled. PET-CT scan was performed before (baseline) and 1 month after EGFR-TKI administration. Up to 5 hottest single tumor lesions (no more than 2 per organ) were considered to be target lesions. Maximum standardized uptake values (SUVmax) were measured, and post-treatment percentage changes in SUVmax (ΔSUV%) were calculated. PET responses were classified using PET response criteria in solid tumors (PERCIST). Then conventional CT scan was performed every 2 months for follow-up. Kappa statistic was used to compare agreement between the RERCIST recommendations-based therapeutic response evaluation and those based on RECIST1.1 criteria. Fisher exact test was used to compare the probability of disease progression in the early metabolic response and non-response groups. Predictive accuracy of ΔSUV% with respect to response or non-progression at CT scan was evaluated by ROC analysis. Progression-free survival (PFS) was determined by Kaplan-Meier survival analysis, and between-group comparison was performed by log-rank test. Results After 1 month of EGFR-TKI treatment, 12 patients (55%) showed partial metabolic response (PMR), 6 (27%) had stable metabolic disease (SMD), and 4 (18%) had progressive metabolic disease (PMD). There was a moderate agreement(Kappa=0.506,P<0.05) between PET response at 1 month based on PERCIST recommendations and CT response at 3 months according to RECIST 1.1. Non-progression was significantly more frequent in patients with an early PMR (χ2=11.941, P=0.005). Progression had been confirmed later during therapy in all patients with PMD . By using ROC analysis, the area under the curve for prediction of response was 0.906 (95% CI, 0.766—1.000; P=0.002), corresponding to a sensitivity of 88.9% and specificity of 84.6% at a cut-off of 40.36% in ΔSUV%. Using a cut-off value of 25.84% in ΔSUV%, highΔSUV% group (ΔSUV% ≥ 25.84%) had significantly longer PFS than low ΔSUV% group (ΔSUV%<25.84%). Conclusion Early assessment of PET-CT at 1 month of EGFR-TKI treatment could be useful to predict tumor response and clinical outcome in patients with NSCLC.

[Summary] The aim of this study was to detect the levels of serum miR-130b expression in patients with type 2 diabetes mellitus and to analyze their correlation with diabetic renal damage. 243 patients with type 2 diabetes mellitus were divided into three groups according to urinary albumin/creatinine ratio ( UACR ): normoalbuminuria group (UACR<30 mg/g, n=103), microalbuminuria group (UACR 30-300 mg/g, n=86), and macroalbuminuria group(UACR>300 mg/g, n=54). The levels of serum miR-130b were validated by realtime polymerase chain reaction. Serum transforming growth factor-β1 (TGF-β1) and tumor necrosis factor-α(TNF-α) were determined by enzyme-linked immunosorbent assay ( ELISA) in all patients and 59 healthy volunteers. Compared with control group, the level of serum miR-130b in the type 2 diabetes mellitus group were significantly decreased, gradually with the increases of UACR. The level of serum miR-130b was inversely correlated with blood urea nitrogen ( r=-0. 295, P<0.05), serum creatinine(r=-0. 316, P<0. 05), UACR(r=-0. 463, P<0. 05), but positively related to the estimated glomerular filtration rate(r=0. 367, P<0. 01). The level of serum miR-130b was also negatively correlated to homeostasis model assessment for insulin resistance, triglyceride, low density lipoprotein-cholesterol, TNF-α, and TGF-β1 (r=-0. 257,-0. 345,-0. 242,-0. 562,-0. 622, all P<0. 01). The present study indicates that serum miR-130b might be a potential new biomarker for early diagnosis of diabetic nephropathy. Serum miR-130b might be involved in the pathogenesis of diabetic nephropathy.
