Increased risk of cerebrovascular mortality in head and neck cancer survivors aged ≥ 65 years treated with definitive radiotherapy: a population-based cohort study.

Background: To investigate the relationship between radiotherapy (RT) and the risk of cerebrovascular mortality (CVM) in head and neck cancer (HNC) survivors aged ≥ 65 years.

Methods: Patients with HNC survivors aged ≥ 65 years diagnosed between 2000 and 2012 were included from the Surveillance, Epidemiology, and End Results database. Kaplan-Meier analysis, Log-rank tests, and Cox proportional-hazards regression models were performed for statistical analyses.

Mechanisms of electroacupuncture effects on acute cerebral ischemia/reperfusion injury: possible association with upregulation of transforming growth factor beta 1.

Electroacupuncture at the head acupoints Baihui (GV20) and Shuigou (GV26) improves recovery of neurological function following ischemic cerebrovascular events, but its mechanism remains incompletely understood. We hypothesized that the action of electroacupuncture at these acupoints is associated with elevated serum levels of transforming growth factor beta 1 (TGF-β1). To test this, we established a rat model of cerebral ischemia by middle cerebral artery occlusion.

Fabrication and characteristics of a multilayered ionic polymer metal composite based on Nafion/tetraethyl orthosilicate and Nafion/MCNT nanocomposites.

Nafion/multi-walled carbon nanotubes (Nafion/MCNT) and Nafion/tetraethyl orthosilicate (Nafion/TEOS) nanocomposites were prepared and used as starting materials in the fabrication of an ionic polymer metal composite (IPMC). Experimental data show that the Nafion/MCNT-based IPMC exhibited a blocking force that is two times higher than that of bare Nafion-based IPMC. This higher blocking force is due to the stable homogeneous dispersions of multiwalled carbon nanotubes as well as to their improved conductivity.

[Efficacy observation on acupuncture prescription of regulating yin-yang and five viscera for intractable insomnia].

Objective: To explore a more optimal therapy for intractable insomnia.

Methods: Seven hundred cases of intractable insomnia that were in accordance with the criteria were randomly divided into an observation group (368 cases) and a control group (332 cases). The acupuncture prescription of regulating yin-yang and five viscera was applied in the observation group, where Dazhui (GV 14), Shenmai (BL 62), Guanyuan (CV 4), Zhaohai (KI 6), Geshu (BL 17), etc.

[Surgical treatment of subluxated lens with cataract].

Objective: To study the surgical treatment of the subluxated lens with cataract caused by broken suspensory ligament of the lens.

Methods: Phacoemulsification combined with intraocular lens implantation was performed in 21 eyes. Extracapsular cataract extraction with small-incision was performed in 6 eyes.
