Patient with pontine warning syndrome and bilateral posterior internuclear ophthalmoplegia: case report.

Background: Capsular warning syndrome was first described in 1993, featured with repetitive episodes of motor and/or sensory dysfunction without cortical signs. Recently, it has been demonstrated that clinically typical capsular warning syndrome can be associated with pontine infarct and the term oepontine warning syndrome was coined.

Case Presentation: A 54-year-old woman with a history of hypertension was seen with profound left-sided hemiplegia.

[Risk factors of middle cerebral artery stenosis in Foshan community, Guangdong province: a longitudinal study].

Objective: To explore the risk factors of middle cerebral artery stenosis (MCAS) in a dynamic manner so as to supply evidence to help prevent cerebral stroke based on the results of epidemiological study.

Methods: 2500 residents were sampled randomly from the residents of Rongqi town and underwent questionnaire survey, physical examination, transcranial Doppler sonography (TCD), and detection of plasma homocysteine (Hcy) in 2002, and 1068 of them that conformed with the criteria: (1) without symptoms of brain ischemia, (2) with temporal window to conduct TCD, and (3) having undergone the questionnaire survey and blood biochemical examination, were enrolled for lone-term study. In 2006 844 of the 1068 residents remained, 277 males and 567 females, aged 60 +/- 10 (12.

[Study on the correlation between hypertension and the indexes of vascular endothelial function among people living in the community].

Objective: To study the features of hypertension and vessel endothelium functional parameter in people living at the community level as well as the risk factors of hypertension. Differences of angiotensin II (Ang II ), prostacyclin (PGI2) and nitric oxide (NO) among normal group and three hypertension groups were also studied.
