RESUMO

In recent years, outbreaks of hand-foot-mouth disease (HFMD) in China, Singapore and other Western Pacific Region, involving millions of children, have become a big threat to public health. This study aimed to quantitatively assess all qualified studies and identify the risk factors for HFMD death. A systematic search of the databases PubMed, Medline, Embase and the Cochrane Library was performed. Study heterogeneity and publication bias were estimated. Seven case-control studies involving 1641 participants (634 died and 1007 survived) were included in the meta-analysis. Human enterovirus 71 infection, male, age ⩽3 years, vomiting, cyanosis, convulsion, duration of fever ⩾3 days, atypical rashes and abdominal distention were not significantly related to HFMD death (P ⩽ 0.05). Lethargy (odds ratio (OR) = 6.62; 95% CI 3.61-12.14; I2 = 0%; P < 0.0001), pneumonoedema/pneumorrhagia (OR = 4.09; 95% CI 2.44-6.87; I2 = 0%; P < 0.0001), seizures (OR = 6.85; 95% CI 2.37-19.74; I2 = 0%; P = 0.0004), dyspnoea (OR = 8.24; 95% CI 2.05-33.19; I2 = 83%; P = 0.003) and coma (OR = 3.76; 95% CI 1.85-7.67; I2 = 0%; P = 0.0003) were significantly associated with HFMD death, which were risk factors for HFMD death.

RESUMO

Objective: To observe the clinicopathologic features and prognostic of patients with IgA nephropathy (IgAN) superimposed on transplant glomerulopathy (TG+ IgAN). Methods: Electronic medical records of Jinling Hospital were searched for TG+ IgAN patients that was diagnosed during January 2004 to December 2016. Clinicopathologic features and prognoses information were retrieved and analyzed. The primary outcome was initiation of replacement therapy or an eGFR declined to<15 ml·min(-1)·(1.73m(2))(-1). Results: A total of 49 patients with pathologically confirmed TG+ IgAN were enrolled in this study. The median time from renal transplantation to allograft biopsy was 85 months. There were 131 patients with TG in the control group. There was no statistical difference in the age, gender, and immunosuppressive regimen during renal biopsy in the two groups. In TG+ IgAN patients, the median serum creatinine level was 175 µmol/L, the median urinary protein was 1.45 g/24 h, and 16.3% of the patients had nephrotic range proteinuria, the incidence of microscopic hematuria was 40.8%, and the average hemoglobin was 105 g/L. In terms of pathology, the degree of glomerular mesangial matrix hyperplasia in the TG+ IgAN group was significantly heavier compared with TG group (P=0.004), and the degree of hyaline degeneration of the small arteries was lighter (P=0.043). There was no significant difference in interstitial inflammation (i), tubulitis (t), glomerulitis (g), peritubular capillaritis (ptc) and intimal arteritis (v). Calculated by Kaplan-Meier method, the median survival time of 49 patients with TG+ IgAN was 36.9 months, and there was no difference in survival rate of allografts compared with TG group. Conclusions: Compared with TG patients without IgA, TG+ IgAN patients had higher incidence of microscopic hematuria, more severe glomerular mesangial matrix hyperplasia, and no significant differences in other clinicopathological features. The prognosis of TG+ IgAN patients was not significantly different from those without IgAN.

RESUMO

Nuclear receptor interacting protein (NRIP1), also known as RIP140, is a transcriptional co-regulator required for the maintenance of energy homeostasis and ovulation. Although several studies have identified roles for NRIP1 in various cell processes, the biological functions of NRIP1 in esophageal squamous cell carcinoma (ESCC) remain unknown. Herein, we demonstrate that NRIP1 inhibits the migration and invasion of ESCC cells. Further mechanistic studies revealed that NRIP1 is directly targeted by miR-548-3p and miR-576-5p. We then identified that miR-548-3p and miR-576-5p regulate the migration and invasion of ESCC cells by inhibiting NRIP1 expression. Interestingly, the expression of miR-548-3p and miR-576-5p in ESCC cell lines and ESCC tissues is up-regulated and NRIP1 is down-regulated relative to controls. A statistically significant inverse association was found between the expression levels of miR-548-3p/miR-576-5p and NRIP1. These combined results reveal novel functions for miR-548-3p, miR-576-5p, and NRIP1 in regulating ESCC cell migration and invasion which are important functions for the metastatic process in esophageal cancer.

RESUMO

Objective: To investigate the associations between various blood test parameters including MLR (monocyte-lymphocyte ratio) and prognosis in post-operative esophagogastric junction cancer patients. Methods: We retrospectively studied the preoperative and postoperative data of 309 patients who underwent radical surgery for esophagogastric junction cancer. The relationship between MLR, neutrophil lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR) and overall survival (OS) was analyzed. Results: The cutoff values of MLR、NLR and PLR were 0.201, 1.697 and 96.960, respectively. The median OS was 51.4 months for all the patients in the study group (n=309). MLR in patients with esophagogastric junction carcinoma was associated with gender, depth of invasion, histological grade, TNM stage, NLR and PLR (P<0.05). PLR was associated with tumor size, TNM stage, NLR and MLR (P<0.05). NLR was associated with gender, tumor size, TNM stage, PLR and MLR (both P<0.05). Univariate analysis showed that tumor size, depth of tumor invasion, metastasis of lymph nodes, pathological grading, nerve infiltration, lymphovascular invasion, TNM staging, PLR and MLR were associated with the median overall survival time (P<0.05). Multivariate analysis showed that TNM stage, nerve infiltration and MLR were independent prognostic predictors for patients with esophagogastric junction cancer (P<0.05), but not PLR or NLR. Setting the optimal cut-off value of the MLR in 0.201, the area under the curve was 0.603, significantly larger than that of PLR and NLR (P<0.05). Conclusions: Preoperative MLR is a very useful predictor of patients with esophagogastric junction cancer who underwent radical rescetion. Preoperative MLR> 0.201 is an independent risk factor for postoperative survival in patients with esophagogastric cancer, and PLR> 96.960 may predict a poor prognosis risk.

RESUMO

INTRODUCTION: Plasma concentration monitoring is commonly used to adjust immunosuppressant dosage in transplant recipients, but adjustment is often based on clinical experience rather than rigorous quantitative indicators. METHODS: We examined the effect of mycophenolate mofetil (MMF) dosage on graft survival by pathologic and immunologic analysis of 88 kidney recipients who were given a postoperative immunosuppressive regimen of tacrolimus (FK506), MMF, and corticosteroids. Patients were given a conventional dosage (≥1.5 g/d; n = 40) or a reduced dosage (n = 48) of MMF owing to postoperative adverse side effects. RESULTS: The reduced-dose group included patients given low doses (≤1.0 g/d; n = 27), ultra-low doses (≤0.5 g/d; n = 15), and those who discontinued MMF (n = 6). The dose reduction group had increased acute rejection, chronic rejection, and graft dysfunction, poorer pathologic scores, and increased cell infiltration of graft tissue (CD4, CD8, CD68, and CD138 positivity) and expression of interleukin-2R and HLA-DR. Finally, hazard analysis indicated that patients given low doses and ultra-low doses of MMF had poorer long-term kidney grafts survival (hazard ratios of 1.52 and 1.78, respectively). CONCLUSIONS: These results indicate the importance of using an appropriate dosage of MMF in kidney transplant recipients.

RESUMO

We report on a general lithography method for high-resolution biomolecule patterning with a bilayer resist system. Biomolecules are first immobilized on the surface of a substrate and covered by a release-and-protection interlayer of water-soluble polymer. Patterns can then be obtained by lithography with a spin-coated resist layer in a conventional way and transferred onto the substrate by reactive ion etching. Afterward, the resist layer is removed by dissolution in water. To demonstrate a high-resolution patterning, soft UV nanoimprint lithography has been used to produce high-density dot arrays of poly-(L-lysine) molecules on a glass substrate. Both fluorescence images and cell proliferation behaviors on such a patterned substrate have shown evidence of improved stability of biomolecule immobilization comparing to that obtained by microcontact printing techniques.
