Comparative StudyComparison of birth weight by gestational age between China and the United States.
To probe into the similarities and differences of birth weight by gestational age between China and the United States by a comparative study. ⋯ American white newborns were heavier than Chinese newborns. The differences were mainly due to race-specific influences, and were related to the differences in socioeconomic and educational background. We suggest that the references of birth weight by gestational age should be formulated separately in China and in the U.S.

The relationship between gut-derived endotoxemia and tumor necrosis factor, neopterin: experimental and clinical studies.
To determine the relationship between gut-derived endotoxemia and tumor necrosis factor (TNF), neopterin/biopterin formation following hemorrhage, trauma and burns. ⋯ These results suggest that gut-derived endotoxemia could account, at least in part, for the inflammatory mediators formation and release, which might be involved in the pathogenesis of sepsis and multiple organ dysfunction following severe hemorrhage, trauma and burns.

Comparative StudyMeasurements of membrane diffusing capacity and pulmonary capillary blood volume in normal subjects and patients with mild emphysema.
To establish predicted values of membrane diffusing capacity (Dm) and pulmonary capacity blood volume (Vc), to compare the predicted values from our equations with those for Caucasians, to determine whether there are changes initially in Dm or Vc in patients with mild emphysema. ⋯ This study provides prediction equations of Dm and Vc. Chinese have a low DLco because their Vc is lower than Caucasians. The DLco and Dm are abnormal in a comparable percentage of patients. In patients with mild emphysema, the Dm becomes abnormal before the Vc.

Glucokinase gene variants in Chinese subjects with the common form of NIDDM.
To determine whether mutation of the coding or junction region of glucokinase gene (GCK) is also the pathogenic cause of the common form of non-insulin-dependent diabetes mellitus (NIDDM) in Chinese. ⋯ (1) Mutation of coding and junction regions of GCK is not the main pathogenic factor of common form NIDDM in Chinese subjects. (2) A variant of GCK intron I b may be found in NIDDM in Chinese, especially in those with early age of onset and/or with positive family history of diabetes. Its role in the expression of GCK remain to be elucidated.

Functional motor innervation of brachial plexus roots. An intraoperative electrophysiological study.
To study the functional motor innervation of C5-T1 nerve roots of the brachial plexus electrophysiologically. ⋯ The brachial plexus is functionally divided into three groups: C5, 6 innervate shoulder and elbow; C8T1 innervate the hand; and C7 innervates shoulder, elbow, wrist and hand. Theoretically, any division of the nerve root alone may not cause damage to limb function.
