Background: The clinic-pathological features and outcomes of Chinese patients with antineutrophil cytoplasmic autoantibody (ANCA)-positive eosinophilic granulomatosis with polyangiitis (EGPA) and renal involvement have not been studied. Methods: Fourteen EGPA patients with renal involvement were included. All patients underwent renal biopsy. Clinic-pathological features and outcomes were retrospectively analyzed. Results: The most common initial symptom of EGPA was asthma (57.1 %), followed by hemoptysis (21.4 %), gross hematuria (14.3 %), and arthritis (7.1 %). All patients had positive serum ANCA (anti-MPO in 12, anti-PR3 in 2). Elevated eosinophils (median 15 %, range 10-45 %) were found in all patients. The median serum IgE level was 463 g/L (range 200-1000 g/L). All patients presented with renal dysfunction, with a median SCr of 5.4 mg/dL (range 1.47-11 mg/dL), seven patients (50 %) required initial renal replacement therapy. Thirteen patients showed hematuria and proteinuria (median 1.1 g/24 h, range 0.5-7.8 g/24 h). Renal biopsy showed pauci-immune segmental necrotizing glomerulonephritis with crescents in 13 patients and acute interstitial nephritis in one patient. Twelve patients (85.7 %) showed renal interstitial eosinophil infiltration, among whom three had eosinophilic granuloma. Among seven patients (71.4 %) who required initial dialysis, 5 discontinued dialysis, one died, one received maintenance dialysis after glucocorticoids plus immunosuppressive for induction treatment. Twelve patients were followed up for a median of 43.5 months (range 6-83 months), during follow-up, two patients progressed to end-stage renal disease, nine had chronic kidney disease with EGFR < 60 mL/min, and two patients had normal EGFR. Conclusions: Renal involvement in ANCA-positive EGPA could be severe and showed varied renal histology. Although intensive immunosuppressive therapy effectively improved the renal function, the long-term renal survival was poor. Early diagnosis and treatment are essential to improve long-term renal survival. © 2016 Chen et al.

The objective of this study was to investigate the role of epithelial cell adhesion molecule (EpCAM) in the genesis and the progress of prostate cancer, especially of castration-resistant prostate cancer. Protein expression of EpCAM in ten pairs of prostate cancer tissues and normal adjacent tissues, plus three cell lines, was examined. Short hairpin RNA (shRNA) interference technique was employed to silence the expression of EpCAM in prostate cancer cell LNCaP and construct a stable transfected cell line. In vitro assay was conducted to analyze the effect of EpCAM expression on the expressions of Androgen receptor (AR), Prostate specific antigen (PSA), and cellular proliferation and invasion. EpCAM was found significantly expressed higher in prostate cancer tissues than in normal adjacent tissues. In three cell lines (DU-145, PC-3, and LNCaP), the expression of EpCAM in LNCaP, androgen-dependent prostate cancer cells, was significantly higher than that in the other two. As EpCAM was silenced in LNCaP, the expression levels of AR and PSA obviously descended, and cellular abilities of proliferation and invasion were obviously inhibited.The overexpression of EpCAM has correlation with the genesis of prostate cancer, especially androgen-dependent prostate cancer. As the expression of AR is facilitated, prostate cancer cells' abilities to proliferate and invade are consequently enhanced. © 2014 International Society of Oncology and BioMarkers (ISOBM).

Objective To evaluate the effects of leukocytes on semen quality. Methods Based on the parameters of semen analysis, the infertile males were divided into three groups such as the normal group, the athenospermia group and the oligozo-athenospermia group. Seminal ROS was detected by using chemiluminescence,meanwhile the ability of WBC producing ROS in semen was determined by fMLP stimulating test. Results Among the three groups, no differences were found in the levels of ROS either in semen or produced by WBC. When the influence of seminal ROS and sperm concentration was normalized, the ROS index of WBC in both athenospermia group and oligozo-athenospermia groups were significantly higher than that in the normal group. Conclusion Relative to sperm concentration, high amount of seminal WBC and ROS level produced by WBC after fMLP stimulation might be the critical factors for decrease in the motility of sperm.

Background: Small studies suggest differences in efficacy and safety exist between olive oil-based (OLIVE) and soybean oil-based (SOYBEAN) parenteral nutrition regimens in hospitalized adult patients. This large, prospective, randomized (1:1), open-label, multi-center, noninferiority study compared the delivery, efficacy, and safety of OLIVE (N = 226) with SOYBEAN (N = 232) in Chinese adults (≥ 18 years) admitted to a surgical service for whom parenteral nutrition was required. Methods: Treatments were administered for a minimum of 5 days up to 14 days (to achieve approximately 25 kcal/kg/ day, 0.9 g/kg/day amino acids, 0.8 g/kg/day lipid). Impact of treatment on anabolic/catabolic and serum inflammatory, chemistry, and hematological markers, safety, and ease of use were assessed. The primary efficacy variable was serum prealbumin level at Day 5. Results: OLIVE (n = 219) was not inferior to SOYBEAN (n = 224) based on the prealbumin least square geometric mean [LSGM] ratio [95 % CI] 1.12 [1.06,1.19]; P = 0.002), improved the anabolic/catabolic status of patients enrolled in the study, and was well tolerated compared with SOYBEAN. Improved anabolic status was supported by significantly higher levels of prealbumin at Day 5, albumin at Day 5 and IGF-1 at Day 14 in the OLIVE group, while catabolism was similar between groups. C-reactive protein, intercellular adhesion molecule-1, procalcitonin, and oxidation were similar in each group, but infections were significantly lower with OLIVE (3.6 % versus 10.4 %; P < 0.01). Conclusions: OLIVE provided effective nutrition, was well tolerated, was associated with fewer infections, and conferred greater ease-of-use than SOYBEAN. © 2015 Jia et al.

Renal fibrosis is a histological outcome of chronic kidney disease (CKD) progression. However, the noninvasive detection of renal fibrosis remains a challenge. Here we constructed a renal fibrosis target mRNA array and used it to detect urinary mRNAs of CKD patients for investigating potential noninvasive biomarkers of renal fibrosis. We collected urine samples from 39 biopsy-proven CKD patients and 11 healthy controls in the training set. Urinary mRNA profiles of 86 genes showed a total of 21 mRNAs that were differentially expressed between CKD patients and controls (P < 0.05), and vimentin (VIM) mRNA demonstrated the highest change fold of 9.99 in CKD vs. controls with robust correlations with decline of renal function and severity of tubulointerstitial fibrosis. Additionally, VIM mRNA further differentiated patients with moderate-to-severe fibrosis from none-to-mild fibrosis group with an area of the curve of 0.796 (P = 0.008). A verification of VIM mRNA in the urine of an additional 96 patients and 20 controls showed that VIM is not only well correlated with renal function parameters but also correlated with proteinuria and renal fibrosis scores. Multiple logistic regression and receiver-operating characteristics analysis further showed that urine VIM mRNA is the best predictive parameter of renal fibrosis compared with estimated glomerular filtration rate, serum creatinine, and blood urea nitrogen. In addition, there is no improved predictive performance for the composite biomarkers to predict renal fibrosis severity compared with a single gene of VIM. Overall, urinary VIM mRNA might serve as a novel independent noninvasive biomarker to monitor the progression of kidney fibrosis. © 2015 the American Physiological Society.
