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.

Objective To determine the perioperative risks of partial hepatectomy by determining the preoperative liver functional reserve in patients with hepatocellular carcinoma (HCC),and to compare the model for end-stage liver disease (MELD) score with the Child-Pugh classification in predicting prognosis.Methods We reviewed the clinical data of 202 patients with HCC who underwent partial hepatectomy.The MELD score and the Child-Pugh classification were determined preoperatively.Results The incidence of postoperative liver dysfunction happened in 44.0％ of Child A patients,50％ in Child B patients,41.6％in patients with a MELD score below 14,and 91.7％ in patients with a MELD score of ＞ 14.The difference between the rates of postoperative liver dysfunction in patients with a preoperative MELD score above 14 and below 14 was significant (P ＜ 0.05),while that between patients with Child-Pugh A and B was insignificant (P ＞ 0.05).The incidences of postoperative liver dysfunction in patient with a MELD ＜ 8,8 ≤ MELD ≤ 14,MELD ＞ 14 were 38.2％,57.6％ and 91.7％,respectively,indicating that there was a positive co-relationship between the MELD score and the incidences of liver dysfunction.The Spearman rank correlation test showed the MELD score was significant correlated with the Child-Pugh score (r =0.404 ; P ＜ 0.05).The areas under the ROC curves of the MELD score and the Child-Pugh score were 0.703 and 0.587 (P ＜ 0.05).Conclusions The MELD score predicted postoperative liver dysfunction more accurately than the Child-Pugh classification.HCC patients undergoing partial hepatectomy with a preoperative MELD score ＞ 14 had a high perioperative risk.To ensure the safety of partial hepatectomy,HCC patients with a preoperative MELD score ＞ 14 requires active preoperative preparation,bringing the score near to or less than 14.

Objective To explore the efficacy and safety of biological mesh during female anterior pelvic organ reconstruction.Methods The 68 consecutive women with symptomatic anterior vaginal wall prolapse in Beijing hospital from January 2010 to June 2013 were divided into two groups:6 cases underwent anterior vaginal wall repair with biological mesh,and 32 cases underwent vaginal approach to paravaginal repair.Preoperative and postoperative pelvic evaluations were performed with the POP-Q system.Patients were followed up at 1,3,6,12,24 months after operation.Objective cure was defined if the lateral sulci of the anterior vaginal walls were at grade 0 and firmly apposed to the lateral pelvic sidewalls.Results Among 68 patients,38 had grade Ⅲ and 30 had grade Ⅳ anterior vaginal wall prolapse.In all patients the anterior vaginal repair was performed successfully.The indexes of operation time,amount of bleeding,the postoperative retention time of catheter and hospital stay had no difference between biological mesh and vaginal approach groups [(88.1±18.3)min vs.(88.0±17.4)min,(140.3±77.6) ml vs.(141.3±64.9) ml,(5.30±1.79) d vs.(4.90±2.34) d,(5.53±2.00)d vs.(5.50±2.08)d,t=0.01,0.05,0.64,0.06,respectively,all P＞0.05].No complication happened during and after operation.No one relapsed in biological mesh group and 4 cases relapsed in paravaginal repair group.The relapse rate between two groups is statistically different(x2 =4.79,P＜0.05).Conclusions The anterior vaginal repair with biological mesh is effective during female anterior pelvic organ reconstruction,but the long-term outcome of biological mesh in pelvic floor construction needs further study.

Objective To evaluate the efficacy and safety of endoscopic therapy in the treatment of symptomatic pancreatic divisum (PD).Methods Data of 8 patients who underwent endoscopic retrograde cholangiopancreatography (ERCP) with the diagnosis of pancreas divisum at our institution from June 2006 to June 2013 was retrospectively analyzed.Results The patients were identified as pancreatic divisum with 28 ERCP procedures.All patients received stent placement,7 underwent minor papilla sphincterotomy,6 pancreatic duct stricture dilatation,and 1 stone extraction.Post-endoscopic retrograde cholangiopancreatography pancreatitis occurred in 1 patient,and no other complications occurred.After a follow-up of 2-47 months,1 patient died of pancreatic carcinoma,3 patients removed the stents,3 patients were followed up regularly,and 1 was unavailable for the interview.The episode of chronic pancreatitis and the extent of abdominal pain decreased after the operations.Conclusion Endoscopic therapy is effective and safe for the pancreatic divisum patients.It can reduce the episode of chronic pancreatitis and relieve the chronic abdominal pain in PD patients with low incidence of complication.

To explore the efficacy of managing benign prostatic hyperplasia (BPH) by family doctor system service in a local community.Among 132 BPH patients recruited from January 2012 to December 2013,74 of them received family doctor system service while the remainder medications only.After 6 months,international prostate symptom score (10.3 ± 5.6) and quality-of-life (2.98 ± 0.95) significantly improved in management group versus control group.And there were significant statistical differences (P ＜ 0.05).The intervention management of family doctor system service is effective for improving the symptoms and quality-of-life of BPH patients.

Objective To compare the efficacy of stents 7 F and 10 F in drainage of pancreatic pseudocyst via EUS-FNA.Methods A retrospective analysis of patients with pancreatic pseudocyst who received endoscopic ultrasonography guided puncture drainage by using 7 F and 10 F double pigtail plastic stent respectively in Drum Tower Hospital of Nanjing University Medical School from 2010 to 2014 was conducted.Patients' hospitalization period, the time for 50％ cyst reduction, removal time, infection rate, and recurrence rate were compared.Results Twenty three patients with pancreatic pseudocyst were included, among whom 14 were male and 9 were female.The age ranged from 13 to 70 with an average of 45.1 years.Eleven patients were treated with 7 F pigtail plastic stents whereas 12 patients with 10 F pigtail plastic stents.All patients were treated with additional 8.5 F joint nose cyst drainage.Four cases in 7 F group got fever, 3 of whom were successful in anti-infection and 1 failed, having to change the stent.One case (9.1％) relapsed without symptoms after 52 months during the follow-up and received no intervention.Five cases in 10 F group got fever, 4 of whom were successful in anti-infection and 1 failed, having to change the stent.One case (8.3％) was identified as mild hemorrhage, and replantation needed to be performed in 1 case (8.3％) because stent was found to slip after 12 days.Two cases (16.7％) relapsed without symptoms after 11 and 24 months respectively and no intervention was received.There was no significant difference in patients' age, cyst size, removal time, infection rate and recurrence rate between the two groups.However, patients in group 10 F had a markedly shorter hospitalization period and time for cyst reduction by at least 50％ than those in group 7 F (P ＜ 0.05).Conclusion 10 F double pigtail plastic stents can drain the cyst faster, shorten the hospital stay, but there is no significant difference in infection or recurrence rate of cyst compared with 7 F stents.

[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.

Objective To explore the roles of MircroRNA-217 ( Mir-217 ) , silent information regulator 1 (Sirt1), and hypoxia-inducible factor-1α(HIF-1α)in high glucose-induced inflammation and fibrosis in rat glomerular mesangial cells( RMCs) . Methods RMCs were pre-incubated with a Sirt1 activator resveratrol prior to high glucose treatment or transfected with Sirt1 small interfering RNA( siRNA) , HIF-1αsiRNA, and Mir-217 inhibitor. Real-time PCR was used to analyze the expressions of Mir-217, Sirt1 mRNA, and HIF-1α mRNA; Western blot was used to observe the protein expressions of Sirt1, HIF-1α, connective tissue growth factor(CTGF), endothelin-1(ET-1), and fibronectin( FN) . Enzyme-linked immunosorbent assay was applied to detect protein expression of transforming growth factor-β1(TGF-β1)and vascular endothelial growth factor(VEGF). Results High glucose increased Mir-217, HIF-1α, CTGF, ET-1, FN, TGF-β1, and VEGF expressions(all P<0. 01), while decreased Sirt1 expression. In addition, Mir-217 gene silencing or 25μmol/L resveratrol suppressed high glucose-stimulated expressions of HIF-1α, CTGF, endothelin-1, FN, TGF-β1, and VEGF(all P<0. 01). Conclusion Mir-217 mediates high glucose-induced inflammation and fibrosis in RMCs via Sirt1/HIF-1αsignal pathway. This study provides new evidence to clarify the protective mechanisms of Sirt1 in diabetic nephropathy.
