Setting up a heart rate alarm limit to decrease oculocardiac reflex during strabismus surgery in children

ZHANG Kangkang, GU Enhua, LU Junjie

Frontiers of Medicine 2008, Volume 2, Issue 3, Pages 295-297 doi: 10.1007/s11684-008-0056-4

Abstract: The aim of this paper is to investigate a method which may decrease the incidence and severity of oculocardiac reflex (OCR) without drugs. One hundred and sixty children undergoing strabismus surgery were allocated to two groups using double-blind randomization. OCR was defined as a decrease of more than 10% from the baseline heart rate during operation. An alarm sounded and a lamp flashed as soon as OCR occurred in group I, and neither of the above happened in group II. OCR occurred (1.151 ± 0.858) times in group I and (2.287 ± 1.371) times in group II ( < 0.05). Heart rate decreased by (23 ± 19) bpm in group I and (35 ± 28) bpm in group II ( < 0.05). The duration of OCR in group I and group II was (4.36 ± 4.26)s and (7.62 ± 6.41)s, respectively ( < 0.05). The recovery time for group I and group II was (15.36 ± 13.28)s and (32.36 ± 19.57)s, respectively ( < 0.05). The numbers of times of interruption were 8 in group I (10%) and 26 in group II (32%) ( < 0.01). This method significantly decreased the incidence and severity of OCR during strabismus surgery in children.

International Comparative Study on the Setting of Medical Specialty Catalogue and Countermeasures

Yu Zhongguang, Zhang Pengjun, Zhang Zhixin, Wang Chen

Strategic Study of CAE 2020, Volume 22, Issue 1, Pages 139-145 doi: 10.15302/J-SSCAE-2020.01.018

Abstract:

The medical specialty catalogue is of great significance for promoting the development of the medical discipline and cultivating qualified medical talents; therefore, a comprehensive and scientific medical specialty catalogue becomes even more important in the context of constructing first-class disciplines in colleges and universities. To promote the progressive development of medical disciplines in China, this research sorted out the medical specialty category by literature analysis, and systematically compared the features and category of medical specialty among the U.S. and the U.K. and China. Several major problems are raised as follow: non-uniform medical specialty and sub-specialty category, outdated arrangement of specialties in quantities and content, premature entry into sub-specialty training, inconsistent categories with standardized residential training, etc. To tackle the problems above, this research suggests that the medical specialty category should be in track with global standard, unified with interdisciplinary approach,and standardized admission and exit criteria be set up, which will prepare future qualified health professionals and promote the advancement of medical disciplines.

South China Sea: Oil and gas outlook

Zhu Weilin,Zhang Gongcheng,Zhong Kai,Liu Baoming

Strategic Study of CAE 2010, Volume 12, Issue 5, Pages 46-50

Abstract:

South China Sea is located in the junction of Eurasian Plate, Pacific Plate and Indian-Australian Plate, and experienced a complex and poly-phase history. A great number of basins with favorable petroleum geological settings and huge resource potentials are distributed in the northern, western and central- southern South China Sea. Among them, the northern shelf region has become an important oil and gas production region and significant breakthrough has attained in the petroleum exploration of northern slope deepwater recently. Currently, petroleum resources in the Chinese conventional boundary line in the South China Sea have been looting by nearby countries, in order to maintain national sovereignty and territorial integrity; efforts must be made to accelerate the oil and gas exploration in the South China Sea.
