2.Related factors of sperm DNA damage: Advances in studies.
National Journal of Andrology 2015;21(8):675-680
The detection of sperm DNA damage, as an important supplement to semen routine examination strategies, has been applied in some clinical andrology laboratories. What factors may lead to sperm DNA damage remains one of the concerns among many andrologists. Present studies show a variety of factors of sperm DNA damage, including age, environmental pollutants such as organophosphorus and organochloride pesticides, plasticizer, heavy metals such as lead, carcinogens such as polycyclic aromatic hydrocarbons (c-PAHs) and zearalenone (ZEA), male reproductive system diseases or systemic diseases such as varicocele, infection, tumor, spermatogenesis and maturation dysfunction, spinal cord injury and endocrine disorders, seasons and temperature, lifestyle, abstinence time, semen refrigeration, semen handling in vitro, and certain medications. Among them, spermatogenesis and sperm maturation dysfunction may be the most secretive factors, which are involved in the molecular mechanisms of sperm chromatin packaging and restructuring, such as the transformation of histone to protamine, single nucleotide polymorphism of genes, and the role of telomere, which may be one of the hotspots in the future studies of sperm DNA damage. Relevant researches in the future are expected to focus on the prevention of sperm DNA damage and clarification of its specific pathogenic mechanisms so as to provide some evidence for its treatment.

3.Neurodevelopmental Assessment Way in Infant
Journal of Applied Clinical Pediatrics 1992;0(06):-
Infant neurodevelopmental assessment is a basic method of estimated high risk infant early development outcome.The early individualized neurodevelopmental assessment consist of monthly observations and evaluations of the infants' behavior modulation,motor repertoire which includes non functional and functional motor,autonomic system stability and muscle tensility,etc.The aims of early neurodevelopmental assessment are to discover the brain developmental abnormal and brain injure induced by various risk factors.Basis of the characteristics of which early brain development have better plasticity,administed early intervention and training,which can intervent neurodevelopmental problems such as cerebral palsy and developmental delay.By developmental assessment also make infant' parents to understand their children' ability and mental specialty,being help for infants' nursing,caring and early education.The applied of neurodevelopmental assessment can provide a new way and idea for infant' early development and intervention.
4.Carotid Atherosclerosis as a Marker of Atherosclerosis of the Thoracic Aorta in the Elderly.
Journal of the Korean Geriatrics Society 2001;5(1):18-23
BACKGROUND: Carotid atherosclerosis and aortic at herosclerosis are both a predictor of atherosclertic cardiovascular diseases. However, the relationship between carotid and aortic atherosclerosis is not well known. METHODS: We performed B-mode ultrasound examinations of the carotid arteries in 38 consecutive elderly cases(13 men, mean age 69+/-3 years and 25 women, mean age 69+/-5 years) who underwent transesophageal echocardiography, to assess whether atherosclerosis in the carotid artery correlates with thoracic aortic atherosclerosis or may be a marker for it. RESULTS: The incidence of carotid and thoracic aortic atherosclerotic plaques were 44.7% and 50%, respectively. There was a significant relationship between carotid atherosclerosis and thoracic aortic atherosclerosis(r=0.532, p<0.01), and a increase in the extent of aortic atherosclerosis with increasing grades of carotid atherosclerosis. In the entire study cases, the presence of carotid atherosclerosis had a sensitivity 63.2%, specificity 73.7%, positive value 72.6% and negative predictive value 66.7% in detec-ting thoracic aortic atherosclerosis. CONCLUSION: In the Korean elderly, B-mode ultra sound examination of the carotid arteries is a easy and useful technique for the prediction of the presence and severity of thoracic atherosclerosis.

6.Changing Role of Nuclear Medicine for the Evaluation of Focal Hepatic Tumors: From Lesion Detection to Tissue Characterization.
Korean Journal of Nuclear Medicine 1998;32(3):211-224
The role of scintigraphic imaging has moved from the detection of lesions to the tissue-specific characterization of lesions over the past 2 decades. Major advances in nuclear medicine imaging include: 1) positron imaging, 2) improved instrumentation, such as the use of multidetector (dual or triple head) gamma cameras for single photon emission computed tomography, and 3) development of numerous new radiopharmaceuticals for positron or single photon imaging ( labeled glucose analogue, amino acids, fatty acids, hormones, drugs, receptor ligands, monoclonal antibodies, etc). These advanced have resulted in a significantly improved efficacy of radionuclide techniques for the evaluation of various of focal gepatic tumors is reviewed in this article with an emphasis on the clinical applications of various tracer studies and imaging findings.

7.Gall bladder wal varices:Easy diagnosis with multiphase incremental bolus dynamic CT.
Journal of the Korean Radiological Society 1993;29(6):1229-1233
Gall bladder wall varices are unusual manifestations of protal hypertention. Authors report 4 cases of gall bladder wall varices which were easily detected in IV bolus CT. All of our cases showed main portal vein obstruction but preserved intrahepatic portal flows with development of cavernous transformation. We could easily identify tortous and tubular structures with strong contrast enhancement in the gall bladder wall, compatible with gall bladder wall varices, at the early phase of IV bolus CT. Comparing with Doppler sonography, IV bolus CT is an easy and useful method for detection of gall bladder wall varices even in case of no prior information for portal vein abnormality.

Objective To explore the characteristics of emotion recognition in children aged 7-14 years. Methods Nine hundred and sixty-one students aged 7-14 years were enrolled to rate the emotion dimensions of valence, arousal and dominance with the scale of Native Chinese Affective Picture System for Children. The relationship among scores of each emotion dimension was analysed, and the differences in age and gender of each emotion dimension were determined. Results For positive pictures (score of valence >6), the score of valence was positively related to that of arousal and dominate (r=0.56, r=0.40, P<0.01). For neutral pictures (score of valence 4-6), the score of valence was negatively related to that of arousal (r=-0.70, P<0.01) and positively related to that of dominance (r=0.69, P<0.01). For negative pictures (score of valence<4), the score of arousal was negatively related to that of dominance (r=-0.95, P<0.01). There were significant differences in scores of emotion dimensions between genders (P<0.05). There were significant differences in scores of arousal and dominance among children with different ages (P<0.01). Age was weakly negatively related to score of arousal (r=-0.18, P<0.01), and was weakly positively related to that of dominance (r=0.10, P<0.01). Conclusion There are significant differences in age and gender for emotion recognition in children, and the ratings are various among pictures with different characteristics, which needs to be considered in further researches.
