Eye Movement Control in Tibetan Reading: The Roles of Word Length and Frequency.

We investigated the effects of word length and frequency on eye movement control during Tibetan reading through two experiments. A preliminary experiment examined the predictive effect of word length and frequency on fixation duration and landing position using multiple linear regression analysis. In the formal experiment, we manipulated the length and frequency of target words simultaneously to investigate the effects of word length and frequency on fixation duration and landing position in Tibetan reading.

Lentivirus-mediated inhibition of tumour necrosis factor-α improves motor function associated with PRDX6 in spinal cord contusion rats.

The recovery of motor function in rats is inhibited following contusion spinal cord injury (cSCI). However, the mechanism of tumour necrosis factor α (TNF-α) in motor function after cSCI associated with peroxiredoxin 6 (PRDX6) remains unknown. We randomly divided rats into four groups: sham, cSCI, vector and lentivirus mediating TNF-α RNA interference (TNF-α-RNAi-LV) group.

[Preliminary analysis on the treatment of ventilator-associated pneumonia caused by pandrug-resistant Acinetobacter baumannii].

Objective: To analyze the clinical features of pandrug-resistant Acinetobacter baumannii (PDR-Ab) in the Chinese PLA General Hospital and compare the efficacies of different antibiotic treatments in aged patients with ventilator-associative pneumonia (VAP) caused by PDR-Ab.

Methods: Data were collected from all isolated PDR-Ab strains in our hospital from April 2009 to April 2010. The clinical features, treatment, and outcomes were retrospectively reviewed.

Effect of simulated microgravity and its associated mechanism on pulmonary circulation in rats.

Objective: To study the effect of Simulated Microgravity and its Associated Mechanism on Pulmonary Circulation in Rats).

Methods: Rat tail-suspension model was used to simulate the physiological effects of microgravity and changes in pulmonary blood vessel morphology, pulmonary arterial and venous blood pressure, pulmonary vascular resistance, pulmonary vasomotoricity, as well as the regulation of pulmonary circulation by cytokines produced and released by the lung of rats were measured.

Results: The walls of pulmonary blood vessels of rats were thickened, and the pulmonary artery was reconstructed with increased pulmonary vascular resistance.

[Salidroside inhibits clinorotation-induced apoptosis in pulmonary microvascular endothelial cells].

Objective: To investigate the inhibitory effect of salidroside (Sal) on pulmonary microvascular endothelial cell (HPMEC) apoptosis induced by simulated microgravity and its mechanism.

Methods: Human pulmonary microvascular endothelial cells cultured in vitro were divided into control group, clinorotation group and clinorotation+Sal pretreatment groups. Microgravity was simulated by clinorotation.

Impact of simulated microgravity on microvascular endothelial cell apoptosis.

Cardiovascular deconditioning is known to occur in astronauts exposed to microgravity. Endothelial dysfunction at microcirculatory sites might contribute to cardiovascular deconditioning induced by weightlessness. Recent studies have reported changes in the morphology and gene expression of endothelial cells exposed to conditions of simulated microgravity.

[Clinical data analysis and chest radiographic features of Wegener's granulomatosis with pulmonary involvement].

Objective: To improve the diagnostic accuracy of Wegener's granulomatosis (WG) with pulmonary involvement by analyzing the clinical data and chest radiographic features.

Methods: The clinical data and chest radiographic features of 43 WG cases with pulmonary involvement were retrospectively analyzed.

Results: Clinically, the patients frequently presented with multi-system involvement, with the incidence of pulmonary involvement of 72.
