question:
the use of antihypertensive medication in older people in order to prevent cardiovascular events is well established. The use of such agents has been encouraged by incentive schemes in the United Kingdom including the Quality and Outcomes Framework. In addition, many guidelines recommend good blood pressure (BP) control in the elderly. However, in older people antihypertensives can cause adverse effects related to hypotension.', 'the aim of this study was to assess the prevalence of low\xa0BP and impact on outcomes, particularly in the presence of antihypertensive treatment, in a primary care population of older people.', 'a retrospective observational cohort study in people over the age of 70 years registered with primary care providers in Kent.', 'a total of 11,167 patients over 70 years old were analysed, 6,373 female (57%). Systolic blood pressure (SBP) was below 120 mmHg in 1,297 people (844 on antihypertensives), below 110 mmHg in 474 (313 on antihypertensives) and below 100 mmHg in 128 (89 on antihypertensives). Hypotension was independently associated with mortality, acute kidney injury and hospital admission.

question:
Hepatocellular carcinoma (HCC) is one of the most common solid tumors and ranks the third leading cause of cancer mortality worldwide. The purpose of this study was to examine the expression dynamics of GOLPH3 in HCC tissue samples, and explore the correlation between GOLPH3 expression and prognosis in patients with HCC.', 'The levels of Golgi phosphoprotein 3 (GOLPH3) mRNA and protein in liver cancer cell lines and fresh tissues were determined by qRT-PCR and Western blotting. Additionally, the protein expression of GOLPH3 was detected by immunohistochemistry.', 'High GOLPH3 expression was positively correlated with serum AFP level (P=0.015) and tumor recurrence or metastasis (P=0.010). In addition, liver cancer patients with high GOLPH3 expression had significantly poorer overall survival (HR, 1.87; 95% CI, 1.19-2.94; P=0.006) and poorer disease-free survival (HR, 1.90; 95% CI, 1.21-2.98; P=0.005) than those with low GOLPH3 expression. The cumulative 5-year survival rate was only 35.19% (95% CI, 26.18%-44.20%) in the high GOLPH3 expression group, whereas it was 55.93% (95% CI, 43.26%-68.60%) in the low GOLPH3 expression group. Furthermore, multivariate Cox regression analysis demonstrated that the expression of GOLPH3, tumor size and tumor multiplicity were independent prognostic predictors for HCC patients.

question:
Ninety-six male adult CD-1 mice were randomly divided into sham, spinal cord injury (SCI)\u200a+\u200avehicle, and SCI\u200a+\u200aIPA-3 groups. Expression of matrix metalloproteinase (MMP)-2 and MMP-9, production of tumor necrosis factors (TNF)-α and interleukin (IL)-1β, tissue edema, blood-spinal cord barrier penetrability, neural cell apoptosis, and neurological function recovery were measured.', 'The aim of the study was to evaluate the effect of specific inhibition of p21-activated kinase 1 (PAK1) by IPA-3 on SCI and the underlying mechanisms thereof.', 'SCI is a devastating clinical condition that may result in long-lasting and deteriorating functional deficits. The major goal of SCI treatment is to limit the development of secondary injury. IPA-3, a PAK1 inhibitor, exhibited neuroprotection against secondary damage after traumatic brain injury and subarachnoid hemorrhage (SAH).', 'MMP-2, MMP-9, and cleaved caspase-3 expression were assessed by Western blot. Inflammatory cytokines TNF-α and IL-1β were detected by enzyme-linked immunosorbent assay (ELISA). The blood-spinal cord barrier disruption was measured by water content and Evans blue extravasation of the spinal cord. Neuronal apoptosis was evaluated by Nissl staining and Terminal-deoxynucleoitidyl Transferase Mediated Nick End Labeling (TUNEL) assay. The locomotor behavior of hind limb was evaluated by Basso Mouse Scale (BMS) at 1, 3, 7, 14, and 28 days post-injury.', 'Compared with SCI\u200a+\u200avehicle mice, IPA-3 treatment showed decreased p-PAK1, MMP-2, MMP-9, cleaved caspase-3, TNF-α, and IL-1β expression. Moreover, inhibition of PAK1 by IPA-3 reduced spinal cord water content and Evans blue extravasation, increased neuronal survival, and reduced TUNEL-positive cells at 24 hours after SCI. Furthermore, IPA-3 improved spinal cord functional recovery 7 days after SCI.
