RESUMO

BACKGROUND: Although adiponectin is a major adipocytokine that affects the pathogenesis of various cardiovascular diseases, its clinical significance in stroke remains controversial. The purpose of this study was to assess the impact of serum adiponectin levels on functional prognosis in patients with ischemic stroke. METHODS: This was a prospective, observational cohort study. Consecutive first-ever ischemic stroke patients without any pre-morbid handicap admitted to our hospital were identified from December 2017 to December 2018. Serum concentration of adiponectin was routinely measured within the first 24 h after admission by a commercially available sandwich ELISA. Associations between adiponectin and either clinical severity at admission, poor outcomes or mortality at 3-month after admission were analyzed using logistic regression to obtain odds ratios (OR) and 95% confidence intervals (CI). RESULTS: The serum level of adiponectin was obtained in 227 patients with a median value of 7.0 µg/ml, which was significantly higher (P < 0.001) than in those heathy control. Adiponectin levels were associated with moderate-to-high stroke, and risk increased by 12% (OR = 1.12; 95% CI 1.03-1.25; P = 0.002). Patients with a poor outcome and nonsurvivors had significantly increased adiponectin levels on admission (P < 0.001, all). In multivariate logistic regression analysis, adiponectin was an independent predictor of functional outcome and mortality, and risk increased by 24% (OR = 1.24, 95% CI 1.13-1.37; P < 0.001) and 31% (1.31 [1.18-1.46], P < 0.001), respectively. Kaplan-Meier analysis suggested that the patients with high serum adiponectin levels had a higher risk of death than those patients with low levels (log-rank test P < 0.001). CONCLUSIONS: Our results show that high adiponectin is associated with stroke severity and support the hypothesis that adiponectin can be serve as a biomarker of poor outcome after stroke, independent of baseline variables.

RESUMO

OBJECTIVE: Glioblastomais is one of the main universal, primary brain cancers, in adults, that has an extremely poor clinical prognosis and a median living period of 12-15 months, accounting for nearly 3-4% of all cancer-related deaths. MicroRNAs (miRNAs) play key roles in cancer pathogenesis by binding the specific and complementary sequences of the 3'UTR of target mRNAs to regulate protein synthesis. Therefore, recognizing functional miRNAs and the fundamental molecular mechanisms will offer novel evidences for the progress of targeted malignancy interferences. Our current study intended to explore the function of miR-28-5p in the promotion of the glioblastoma. METHODS: Human glioblastoma tissues, paired nearby normal/non-tumor tissues were accumulated from our hospital. Human glioblastoma SNB19 cells were infected by miR-28-5p mimics or miR-28-5p siRNA by lentivirus. Tumor spheres formation was used to evaluate the growth ability. MTT examine was applied for measuring viability. BrdU cell proliferation assay was applied to uncover the proliferation ability of SNB19 glioblastoma cells. Real-time PCR was conducted to identify miRNA expression. Western blot analysis was employed to measure protein expression. Dual-luciferase FOXO1-3'UTR reporter was used to determine the ability of miR-28-5p to regulate FOXO1. RESULTS: Expression of miR-28-5p was explored to be increased in both human glioblastoma tissues and cell lines. Up-regulated miR-28-5p expression promotes tumor spheres formation, cell viability, and proliferation ability of glioblastoma cells. FOXO1 was found to be the target of miR-28-5p and the activity of FOXO1 was down-regulated by miR-28-5p in glioblastoma cells. CONCLUSIONS: MiR-28-5p is an oncogene and promotes the occurrence of glioblastoma by directly targeting the FOXO1.

RESUMO

The purpose of this study was to determine the impact of early (⩽6 months old), midterm (6-12 months old) and late (>12 months old) endoscopic third ventriculostomy (ETV) on the operative success rate and postoperative neurodevelopmental outcome of children with congenital obstructive hydrocephalus. We divided 63 children into three groups according to whether they underwent early, midterm or late ETV. Their preoperative developmental quotient (DQ) was assessed using the Gesell developmental diagnosis schedule (GDDS). Three and 6months after the initial procedure, GDDS was used to obtain postoperative DQ from two assessments (blinded and non-blinded). Meanwhile, two observers studied the operative success rate of initial ETV. There were no substantial differences between blinded and non-blinded assessments. The success rate of early ETV was only 20.8%. By contrast, this rate was 55% and 73.7% for midterm and late ETV, respectively. Before operation, we observed severe developmental abnormalities in all children (DQ score<40). However, children in midterm and late ETV groups achieved improvement after the operation, which was particularly remarkable in late ETV group. Six months after the first surgery, 16 (84.2%) children in the late ETV group, nine (45%) in the midterm ETV group and four (16.7%) in the early ETV group had moderate developmental disability. Nevertheless, overall prognosis for the three groups was not optimistic. There were no children with mild neurodevelopmental disability or normal function. Our data confirmed that age is a determinant for ETV effectiveness and overall prognosis.
