Effect of perioperative blood pressure variability on cerebral hyperperfusion syndrome after carotid artery stenting: A retrospective study.

Objective: To investigate the effect of perioperative blood pressure variability on cerebral hyperperfusion syndrome after carotid artery stenting.

Methods: A retrospective analysis was conducted of data collected from 418 patients who underwent carotid artery stenting in Guangxi Zhuang Autonomous Region People's Hospital in China. The blood pressure data were collected during operation (after balloon dilation, before stent release, after stent release) and within 3 days after the operation.

Genetic Polymorphism of rs13306146 Affects Expression and Associated With Postpartum Depressive Symptoms in Chinese Women Who Received Cesarean Section.

Postpartum depressive symptom (PDS) is a common psychological and mental disorder after giving birth. Our previous studies showing the application of dexmedetomidine, an α-AR agonist, can significantly improve maternal sleep, as well as relieve and reduce the incidence of PDS. This study investigated the association between α AR gene polymorphisms and PDS.

Down-regulated Na(+)/K(+)-ATPase activity in ischemic penumbra after focal cerebral ischemia/reperfusion in rats.

This study was aimed to examine whether the Na(+)/K(+) adenosine triphosphatase (Na(+)/K(+)-ATPase) activity in ischemic penumbra is associated with the pathogenesis of ischemia/reperfusion-induced brain injury. An experimental model of cerebral ischemia/reperfusion was made by transient middle cerebral artery occlusion (tMCAO) in rats and the changes of Na(+)/K(+)-ATPase activity in the ischemic penumbra was examined by Enzyme Assay Kit. Extensive infarction was observed in the frontal and parietal cortical and subcortical areas at 6 h, 24 h, 48 h, 3 d and 7 d after tMCAO.

Evaluation of hepatocellular carcinoma using contrast-enhanced ultrasonography: correlation with microvessel morphology.

Background: Contrast-enhanced ultrasonography (CEUS) is an important technique for depiction and assessment of tumor vascularity. This study aimed to explore the relationship between the morphological characteristics of tumor microvessels and enhancement patterns on CEUS in hepatocellular carcinoma (HCC).

Methods: Eighty patients with HCC underwent CEUS using SonoVue before hepatectomy.

[Expression and significance of NGX6 gene in human hepatocellular carcinoma].

Objective: To examine the expression of NGX6 gene and to investigate its association with the clinico-pathological characteristics in hepatocellular carcinoma(HCC).

Methods: Samples from 45 patients were divided into the hepatocellular carcinoma tissue group and the matched paracancerous tissue group. Reverse transcription polymerase chain reaction(RT-PCR) was used to detect the expression of NGX6 gene in the hepatocellular carcinoma and the surrounding normal tissue specimens.

[Contrast enhanced power Doppler in evaluating the angiogenesis in hepatocellular carcinoma].

Objective: To evaluate the role of contrast enhanced power Doppler in evaluating tumor angiogenetic activity.

Methods: Thirty-two patients with hepatocellular carcinoma were analysed. Flow signals of hepatocellular carcinoma were observed by power Doppler imaging after the injection of contrast agent, and then the relative perfusion rate and blood flow were assessed.
