Platelet CFTR inhibition enhances arterial thrombosis via increasing intracellular Cl concentration and activation of SGK1 signaling pathway.

Platelet hyperactivity is essential for thrombus formation in coronary artery diseases (CAD). Dysfunction of the cystic fibrosis transmembrane conductance regulator (CFTR) in patients with cystic fibrosis elevates intracellular Cl levels ([Cl]) and enhanced platelet hyperactivity. In this study, we explored whether alteration of [Cl] has a pathological role in regulating platelet hyperactivity and arterial thrombosis formation.

Clcn3 deficiency ameliorates high-fat diet-induced obesity and adipose tissue macrophage inflammation in mice.

Obesity induces accumulation of adipose tissue macrophages (ATMs) and ATM-driven inflammatory responses that promote the development of glucose and lipid metabolism disorders. ClC-3 chloride channel/antiporter, encoded by the Clcn3, is critical for some basic cellular functions. Our previous work has shown significant alleviation of type 2 diabetes in Clcn3 knockout (Clcn3) mice.

Xyloketal B exerts antihypertensive effect in renovascular hypertensive rats via the NO-sGC-cGMP pathway and calcium signaling.

Xyloketal B (Xyl-B) is a novel marine compound isolated from mangrove fungus Xylaria sp. (No 2508). We previously showed that Xyl-B promoted endothelial NO release and protected against atherosclerosis through the Akt/eNOS pathway.

LNK deficiency aggravates palmitate-induced preadipocyte apoptosis.

LNK (SH2B3) is an intracellular adaptor protein that negatively regulates cellular proliferation or self-renewal of hematopoietic stem cells and some other progenitor cells. LNK is also recognized as a key regulator of insulin resistance and inflammatory responses in several tissues and organs. The function of LNK in adipose tissue is unknown.

Elevated preoperative peripheral blood monocyte count predicts poor prognosis for hepatocellular carcinoma after curative resection.

Background: Peripheral blood monocyte count is an easily assessable parameter of systemic inflammatory response. The aim of this study was to determine whether monocyte count was prognostic in hepatocellular carcinoma (HCC) following hepatic resection.

Methods: We retrospectively reviewed 351 patients with HCC treated with hepatic resection from 2006 to 2009.

Vascular fibrosis in atherosclerosis.

Vascular fibrosis, characterized by reduced lumen diameter and arterial wall thickening attributable to excessive deposition of extracellular matrix (ECM), links with many clinical diseases and pathological progresses including atherosclerosis. It involves proliferation of vascular smooth muscle cell (VSMC), accumulation of ECM and inhibition of matrix degradation. The risk factors associated with cardiovascular disease, including hypertension, hyperglycemia, dyslipidemia and hyperhomocysteinemia (HHcy), are also suggested as initiation and progression factors of vascular fibrosis.

Involvement of Kv1.5 protein in oxidative vascular endothelial cell injury.

Endothelial injury related to oxidative stress is a key event in cardiovascular diseases, such as hypertension and atherosclerosis. The activation of the redox-sensitive Kv1.5 potassium channel mediates mitochondrial reactive oxygen species (ROS)-induced apoptosis in vascular smooth muscle cells and some cancer cells.

[Effects of preoperative oral glucose on perioperative insulin resistance and plasma proteins of intestinal surgery].

Objective: To investigate the effects of oral intake of glucose solution before surgery on the pH at the lower esophagus, perioperative blood glucose level, and plasmic protein in patients undergoing radical resection for colorectal cancer.

Methods: Between January 2008 and December 2008, 60 patients undergoing radical surgery for colorectal cancer were enrolled and randomized into three groups using the table of random digits. Four patients were withdrawn from the study.

[Application of remifentanil in neurosurgical anesthesia: a multi-center study].

Objective: To observe the hemodynamic changes, recovery profiles, and side effects of propofol and remifentanil anesthesia by target controlled infusion (TCI). At different neurosurgical stages in patients undergoing neurosurgical operations.

Methods: 230 patients were scheduled for elective craniotomy in five hospitals in Beijing, Changsha, and Guangzhou.

Low central venous pressure reduces blood loss in hepatectomy.

Aim: To investigate the effect of low central venous pressure (LCVP) on blood loss during hepatectomy for hepatocellular carcinoma (HCC).

Methods: By the method of sealed envelope, 50 HCC patients were randomized into LCVP group (n=25) and control group (n=25). In LCVP group, CVP was maintained at 2-4 mmHg and systolic blood pressure (SBP) above 90 mmHg by manipulation of the patient's posture and administration of drugs during hepatectomy, while in control group hepatectomy was performed routinely without lowering CVP.
