[The occurrence of hypertension in patients with obstructive sleep apnea syndrome].
To determine the changes in blood pressure (BP) and its correlated factors in patients with obstructive sleep apnea syndrome(OSAS). ⋯ The transient hypertension during apnea might be recurrent episodes in patients with OSAS who have normal daytime BP. Nocturnal hypoxemia and apnea length might play a role in nocturnal elevation in BP in patients with OSAS. Hypoxemia was not the major factor in BP elevation after obstructive apneas. Simple oxygen administration could not normalize the elevation in BP during apnea in patients with OSAS and NCPAP might be an appropriate therapy.

[Inhibition of potassium channel by chronic hypoxia on pulmonary artery smooth muscle cells in rats].
To explore the possible effect of potassium channel in chronic hypoxic pulmonary hypertension. ⋯ The persistent decrease of potassium channel activity may contribute to setting the development of chronic hypoxic pulmonary hypertension. Cromakalim, one of potassium channel openers, can decrease the pulmonary hypertension induced by chronic hypoxia and may be a new effective drug for treatment of hypoxic pulmonary hypertension.

To explore the cause, classification, incidence, diagnosis and treatment of pulmonary sequestration. ⋯ Pulmonary sequestration is not a rare illness. The diagnosis mainly depends on X-ray. Sometimes, bronchography, retrograde arteriography or CT can also make the diagnosis correctly. Special attention should be paid to avoiding injure to the vessels which supply the isolated lung during operation.
