Objective To evaluate the effects of prostaglandin E1 (PGE1 ) infused in the pulmonary artery of the ventilated lung on hemodynamics and pulmonary gas exchange during one-lung ventilation (OLV).Methods Experiments were performed on 12 healthy pigs of both sexes (6 males , 6 females) aged 3 months, weighing 14-17 kg. The animals were anesthetized with intramuscular ketamine 15-20 mg?kg-1 , diazepam 1.5-2.0 mg?kg-1 and atropine. The animals were mechanically ventilated after tracheal intubation (FiO2 = 0.7, VT = 12-15 ml?kg-1, RR=15bpm, I:E=l:2). PaCO2 was maintained at 35-45 mm Hg. Swan-Ganz catheter was positioned in the right pulmonary artery via the left femoral vein. The right femoral artery was cannulated for BP monitoring and blood sampling. Anesthesia was maintained with a mixture of ketamine 100 mg and succinylcholine 100 mg in 2% procaine 100 ml infused i.v. at a rate of 2-3 ml?kg-1?h-1. The animals were placed in right lateral position. The left chest was opened and OLV was established by clamping the left main bronchus. During OLV RR was increased from 15 to 20 bpm but the minute ventilation remained unchanged. The animals were randomly divided into 2 groups of six : group A and B. Group A received PGE1 infusion in the right pulmonary artery with an initial dose of 0.01 ?g?kg-1?min-1 which was gradually increased to 0.02, 0.04, 0.06, 0.08 and 0.1 ?g?kg-1?min-1 . Theinfusion of each dose was maintained for 20 min. In group B normal saline was infused instead of PGE1. MAP, HR, CVP, PCWP, CO, PaO2 PvO2 were recorded at each dose and at 20, 40, 60 min after PGE1 infusion was terminated. Qs/Qt, PVR and SVR were calculated.Results MPAP, PVR, SVR, peak inspiratory pressure (PIP) and Qs / Qt significantly increased while CO, Cdyn and PaO2 significantly decreased (P 0.05) and a significant decrease of MPAP and PVR ( P

Objective To explore the effect of swallowing training on dysphagia in patients with head and neck neoplasm receiving ra-diotherapy. Methods 60 patients with head and neck neoplasm receiving radiotherapy from March, 2014 to August, 2015 were divided into intervention group (n=30) and control group (n=30) randomly. The control group received routine nursing and relevant health education, while the intervention group received swallowing training from 2 weeks before to 3 months after radiotherapy. They were assessed with Functional Oral Intake Scale and M. D. Anderson Dysphagia Inventory 1 week, 3 months after radiotherapy. Results The scores of Function-al Oral Intake Scale (Z=-3.195, P<0.01), the total score of M. D. Anderson Dysphagia Inventory and the subscores (t>4.385, P<0.01) were better in the intervention group than in the control group 1 week after radiotherapy, as well as 3 months after radiotherapy (Z=-4.436, P<0.01;t>5.361, P<0.01). Conclusion Swallowing training could improve the condition of dysphagia of head and neck neoplasm patients after radiotherapy.

Alcoholic liver disease ( ALD ) , a chronic progres-sive disease, threatens human health seriously. An increasing number of studies have shown that gut flora dysbiosis plays an important role in the development of ALD. Intestinal microbiota maintains a steady state under normal conditions, regulating gut flora normal physiological function. However, chronic alcohol consumption produces intestinal bacteria overgrowth and dysbio-sis, including the alteration of the composition of intestinal mi-croflora, the increment of gut permeability and bacterial translo-cation. Subsequently, the host immune is activated, promoting the production of inflammatory cytokines in liver, which plays a central role in the development of ALD. Notably, the supple-ment of prebiotics or probiotics reverses the intestinal flora disor-der,ameliorating the clinical symptoms effectively in ALD pa-tients. The evidence impies that the modulation of dysbiosis may be effective in the prevention and treatment of ALD. This review summarizes the research progress on the mechanism of the devel-opment of dysbiosis-mediated ALD, to provide a theoretical basis for the research on intestinal flora and ALD.
