Objective: To study the clinical therapy and prognosis in children with transient congenital hypothyroidism (CH).Methods: Fifty-seven children with CH diagnosed after neonatal screening were treated with low-dosage levothyroxine (L-T4).Follow-up evaluation included the determination of TT3, TT4 and TSH serum levels and the assessment of thyroid gland morphology, bone age, growth development and development quotients (DQ). A full check-up was performed at age 2, when the affected children first discontinued the L-T4 treatment for 1 month, and one year later. Development quotients were compared (16.25±3.87) μg/d. Mean duration of therapy was (28.09±9.56) months. No significant difference was found between study group and control group in the DQ test (average score (106.58± 14.40) vs (102.4±8.6), P＞0.05) and 96.49% of the CH children achieved a test score above 85. Bone age, 99mTc scans and ultrasonographic findings were all normal, and evaluation of physical development was normal too, as were the serum levels of TT3, TT4 and TSH after one year of follow-up. Conclusion: A L-T4 dosage of and physical development at age 2. So it is possible for CH children to stop taking medicine if their laboratory findings and physical development are all normal after regular treatment and 2～3 years of follow-up. 相似文献

Objective： To discuss possible relationships between class In malocclusion and perioral forces by measuring the pressure from the lips and the tongue of children with class nI malocclusion. Methods： Thirty-one children with class In malocclusion were investigated and their perioral forces were measured at rest and during swallowing under natural head position by a custom-made miniperioral force computer measuring system. Results： The resting pressures exerted on the labial side and palatine side of the upper lett incisor, as well as the labial side and lingual side of the lower lett incisor, were 0 g/cm^2, 0 g/cm^2, 0.57 g/cm^2 and 0.23 g/cm^2, respectively. Correspondingly, the swallowing forces were 2.87 g/cm^2, 5.97 g/cm^2, 4.09 g/cm^2 and 7.89 g/cm^2, respectively. No statistical difference between muscular pressure and gender existed. During swallowing, the lingual forces were significantly higher than the labial forces （P〈0.01）, however, at rest there was no significantly different force between these two sides. Compared to the normal occlusion patients, children with class Ⅲ malocclusion had lower pedoral forces. The upper labial resting forces （P〈0.01）, the lower labial resting forces （P〈0.05） and all the swallowing pressures from the lips and the tongue （P〈0.01） showed statistical differences between the two different occlusion conditions. Meanwhile, no significant difference was found for the resting pressure from the tongue between class Ⅲ malocclusion and normal occlusion. Conclusion： Patients with class Ⅲ malocclusion have lower perioral forces and this muscle hypofunction may be secondary to the spatial relations of the jaws. The findings support the spatial matrix hypothesis. 相似文献

This study investigates some of the differences and similarities between Kurdish-Persian bilinguals and Persian monolinguals with respect to the use of referring expressions in spoken narratives. The narratives were elicited from 36 participants, consisting of 24 bilinguals （Groups l and 2） and 12 monolinguals （Group 3） in the first four grades of primary school using picture narrative book. The results have revealed that Group 1 （bilinguals told the story in Kurdish） used definite noun phrases most frequently followed by zero anaphors, indefinite noun phrases, and pronouns. Group 2 who narrated the story in Persian produced definite nouns most frequently followed by pronouns, zero anaphors, and indefinite noun phrases. Group 3 （Persian monolinguals） employed definite noun phrases most frequently followed by zero anaphors, pronouns, and indefinite noun phrases. The significant difference between Groups 1 and 2 and Groups 2 and 3 has been in indefinite noun phrases and between Groups 1 and 3 in the use of pronouns. One reason is that children universally apply similar strategies regardless of their first language （L l）. The conclusion is that some of the differences are due to the difference in the structure between Persian and the dialects of Kurdish. 相似文献

In national perception, education is essentially for all. This is fundamental to all-round development, material and spiritual. It refines sensitivities and perceptions that contribute to national cohesion, a scientific temper and independence of mind and spirit--thus furthering the goals of socialism secularism and democracy enshrined in our constitution. The objective of the study focuses on achievement of children with learning disability in science. There are 5 null hypothesis tested in this research. The sample used in this study includes 35 children with learning disabilities in experimental group and 42 children with learning disabilities in control group. The different views taken on special education have ignited spark of controversies over segregating some children from the mainstream and providing them with extra opportunities. There are arguments for and against both special education and integrated education. Special education means the specifically designed instruction that meets the unusual needs of special children. It requires special materials, teaching, techniques, equipment and facilities. The design was an experimental research pre and post-test equivalent group. The research shows that there is no significant difference in all learning objective such as knowledge, comprehension and skill between control group and experimental group in the pre-test. This two sample groups also did not show any significant difference in the pre-test irrespective of gender, educational qualification of the teacher, years of experience of the teacher, parents＇ education, parents＇ profession, parents＇ income, type of management and type of school. On the other hand, for the post-test all the characteristics show that there are significant differences. This shows that there are effects on the treatment group in learning objective. Furthermore the experimental group showed significantly higher gain score than the control group with regard to the learning objective which comprises of knowledge, comprehension, application and skill. 相似文献

Characteristics of strong winds at the Runyang Suspension Bridge based on field tests from 2005 to 2008 总被引：1，自引：0，他引：1
Field measurement of strong wind characteristics is of great significance for the development of bridge wind engineering. Located in east China, the Runyang Suspension Bridge （RSB） with a main span of 1490 m is the longest bridge in China and the third longest in the world. During the last four years, the RSB has suffered from typhoons and strong northern winds on more than ten occasions. To determine the strong wind characteristics of the RSB, wind measurement data obtained from field tests during strong winds and data from the wind environment monitoring subsystem of the structural health monitoring system （SHMS） of the RSB were combined to analyze the wind speed and direction, variation in wind speed with height, turbulence intensity, turbulence integral length, wind friction speed and the power spectrum. Comparative studies on the characteristics of these different strong winds were carried out based on the current wind-resistant design specification for highway bridges. Results showed that some regularity in wind characteristics can be found in these different typhoons passing through the RSB. The difference between a strong northern wind and a typhoon is relatively clear, and in summer the typhoon is the dominant wind load acting on the RSB. In addition, there were some differences between the measured strong wind characteristics and the values suggested by the specification, especially in respect to turbulence intensity and turbulence integral length. Results provide measurement data for establishing a strong wind characteristic database for the RSB and for determining the strong wind characteristic parameter values of this coastal area in east China. 相似文献

In the field of translation studies, scholars’ understanding of translation in its traditional sense; has shifted along with the popularity and prosperous development of cultural studies in the recent years. Translation is no longer regarded as merely a cross-linguistic activity but essentially cross-cultural communication. Cultural factors begin to gain more and more attention to translators. Nida even claims that"for truly successful translating, biculturalism is even more important than bilingualism". Therefore, this thesis will focus on analyzing the influence of cultural differences between Chinese and English on the English translation. This thesis firstly discusses embodiments of cultural differences between Chinese and English; after that, it focuses on influences of cultural differences on translation; last but not least, this thesis also suggests some translating techniques. 相似文献

This study is aimed to investigate the clinical significance and the short-term prognostic value of frag- mented QRS （fQRS） for patients with acute myocardial infarction （AMI）. Three hundred patients with AMI were tested with retrospective analysis on the patients＇ clinical information, hospitalized treatment, fQRS onset time, location of lesions, and other relevant data, in order to assess the relationship between the presence of fQRS and its prognosis. The rates of malignant cardiac arrhythmia, left ventricular systolic dysfunction （LVSD）, and mortality in the positive fQRS group were 13.6%, 29.2%, and 23.7%, respectively, with all showing a p value 〈0.05. For the ST segment elevation myocardial infarction （STEMI） subgroup, all the rates showed significant differences with a p value 〈0.01, while for the non-STEMI （NSTEMI） subgroup showed no significant differences. In patients with a positive fQRS, there were no differences in malignant cardiac arrhythmia between patients with and without percutaneous coronary in- tervention （PCI） （p〉0.05）. As for the LVSD and mortality, the p values between patients with and without PCI were 0.031 and 0.000, respectively, suggesting statistical significance. The results imply that AMI patients with positive fQRS especially for the patients with STEMI had higher rates of malignant cardiac arrhythmia, LVSD, and mortality than the non-fQRS group. Patients of AMI with positive fQRS, who underwent early revascularization, could lower the incidence of the cardiovascular event. In addition, the presence of fQRS could be used as an indication of early in- tervention treatment for patients. 相似文献

The worries ＆ wishes of 14 -19 years-old adolescents of Abadeh, Bavanat ＆ Khorambid cities in the north of Fats province are investigated in this research. The wishes ＆ worries are measured by wishes measurement scale （WMS） and Ahwaz worry inventory （AWI） respectively. The Ss consisted of 300 Adolescents （150 girls ＆ 150 Boys） that selected by ratio sampling method. The most important results of project are as following ：（1） there are significant positive correlations between wishes ＆ worries. （2） Girls in comparison with boys have been significantly higher on emotional-psychological and moral-philosophical wishes. Further more, they haven＇t been different on somatic- physical ＆ social - familial wishes. （3） In self -esteem, vocational, other relations, insecurity, detail problems worries and AWI, girls have been significantly worrier than boys. While in cognitive ＆ future worry factors their situation have not been different. （4）. According to the influence of gender on adolescents, worries and wishes for prompting of their mental health should be used in different ways. 相似文献

The Difference of Cognitive Process Between Native Language Acquisition and Second Language Learning
The Acquisition-Leaming distinction is the most fundamental of all the hypotheses in Krashen＇s theory and the most widely known among linguists and language practitioners. The relationship between the cognitive development and language acquisition is one of the linguists＇ concerns. Cognitive process is usually defined as any mental process which learners make use of in language learning, such as inferencing, generalization, deductive learning, monitoring and memorizing. Cognitive process can also be thought of as the development and maturation of cognitive capacity. This paper will focus on the difference of cognitive process between native language acquisition and second language learning. 相似文献

Attention-deficit/hyperactivity disorder （AD/HD） negativelly affects the cognitive and psychomotoric spheres of the pupil＇s social behavior and social adaptation. The review of many studies states that pupils with AD/HD achieve worse learning results because of insufficiently functioning cognitive processess, such as attention, （work） memory, thinking, problem solving, language, small- and large- scale motorics. Behavioral features, exhibited with AD/HD, include low-frustration tolerance, temper problems, persistence, emotional liability, depression, peer rejection, poor self-concept and poor self-esteem. Because of insufficiency of the cognitive processes, the difficulties of social behavior and social adaptation, pupils with AD/HD more often have a dysfunction of pupils＇ role that manifests by learning difficulties and behavior problems. The manifestation of the disorder in the younger school age in the context of children＇s school activities and roles actualizes the exceptional interest of the educational science in the analyzed phenomenon. The search and construction of effective means of socio-educational help for AD/HD primary class pupils should be associated with coordination and adaptation of different effective educational methodologies of different conceptual origin. In order to develop cognitive, psycho-motoric abilities and social behavior of the group of primary class pupils with AD/HD （N=22）, activities of supplementary education were organized after classes （their duration was 6 months）. During the forming experiment, original methodologies were constructed and national and foreign researchers＇ educational methodologies were adapted and tested in new, specific conditions （methods of fairy-tales, correction of cognitive behavior, graphical-logical tasks, games in the sport hall）. Even by relatively rare activities of supplementary education in a homogeneous group of children suffering from AD/HD positive changes of cognitive, psychomotoric sphere, social behavior and social adaptation were achieved. 相似文献

In the present work, the potential of acaricidal activity of chamomile flowers＇ extract was studied against engorged Rhipicephalus annulatus tick under laboratory condition. For this purpose, the engorged females ofRhipicephalus annulatus were exposed to two-fold serial dilutions of chamomile flowers＇ extract （0.5%, 1.0%, 2.0%, 4.0% and 8.0%） using ＂dipping method＂ in vitro. The engorged ticks were immersed in different plant dilutions （five ticks for each dilution） for l rain and they were immediately incubated in separate Petri dishes for each replicate at 26℃ and 80% relative humidity. Mortality rate for each treatment was recorded 5 d after incubation.
The mortality rate caused by different dilutions of chamomile flowers＇ extract ranged from 6.67% to 26.7%, whereas no mortality was recorded for non-treated control group. The mass of produced eggs varied from 0.23 g （in 8.0% solution） to 0.58 g （in control）, with no statistical differences between the treatments and control （/＇〉0.05）. Also the chamomile flowers＇ extract in highest concentration used （8.0%） caused 46.67% failure in egg laying in engorged females while no failure was observed for non-treated control group. Macroscopic observations indicated that in effective concentrations of plant （4.0% and 8.0%）, patchy hemorrhagic swelling appeared on the skin of treated ticks. The results presented for the first time in this study imply that chamomile may be considered as a promising plant for biocontrol of cattle fever tick disease in the field condition. 相似文献

The issue of bilingualism has been widely explored in the past decades,showing that there are multiple positive effects of"additive bilingualism".Such positive factors are closely linked with children’s cognitive development and intelligence.This paper gives a detailed review on how bilingualism plays a role in children’s divergent thinking ability.Fully taking advantage of such positive effects in language education should be a significant part for bilingual education and foreign language programs.Thus,this paper further discusses the educational implications of these theoretic findings,suggesting that an additive bilingual environment should be cultivated through multiple ways of curriculum and program planning. 相似文献

Study on the neurotoxic effects of low-level lead exposure in rats 总被引：10，自引：0，他引：10
Objective: To investigate effects of developmental lead exposure on nitric oxide synthase (NOS) activity in different brain regions and on N-methyl-D-aspartate (NMDA) receptor mRNA expression in the hippocampus of rats. On the basis of these observations, we explored possible mechanisms by which lead exposure leads to impaired learning and memorizing abilities in children. Methods: A series of rat animal models exposed to low levels of lead during the developing period was established (drinking water containing 0.025%, 0.05% and 0.075% lead acetate). NOS activities in the hippocampus, the cerebral cortex, the cerebellum and the brain stem were determined with fluorescence measurement and levels of mRNA expression of the NMDA receptor 2A (NR2A) subunit and NMDA receptor 2B (NR2B) subunit in the rat hippocampus were measured with Retro-translation (RT-PCR). Results: There were no differences in the body weight of rat pups between any of the groups at any given time (P>0.05). The blood lead level of Pb-exposed rat pups showed a systematic pattern of change: at 14 d of age, it was lower than that at 7 d of age, then rising to the peak level at 21 d and finally falling to lower levels at 28 d. The hippocampal NOS activities of lead-exposed groups were all lower than that of the control group on the 21st and 28th day (P<0.01). NOS activities in the cerebellum of lead-exposed groups were all lower than that of the control group on the 21st and 28th day (P<0.001) and the NOS activity of the 0.025% group was significantly lower than that of the 0.05% and 0.075% groups on the 28th day (P<0.05). NOS activity in the cerebral cortex of the 0.075% group was significantly lower than that of the control, 0.025% and 0.05% groups on the four day spans (P<0.001). There was no significant difference of NOS activity in the brain stem between any lead-exposed group and the control group on the four day spans. In the 0.05% and the 0.075% groups, the level of NR2A mRNA expression was higher than that in the control group at 7 d and 14 d of age (P<0.05). In the 0.025% group, the level of NR2A was found to be higher than that in the control group at 7 d of age only (P<0.05). No significant differences were found for the levels of NR2B mRNA expression between any of the groups at any given time. Conclusions: NOS activity in the hippocampus, the cerebral cortex and the cerebellum are inhibited by lead exposure. The degree of the inhibitory effect depends on the time span of exposure and the lead concentration. Developmental low-level lead exposure was found to raise the level of NR2A mRNA expression in the hippocampus of rats. Developmental low-level lead exposure does not affect the level of NR2B mRNA expression in the hippocampus. 相似文献

It is of great importance to obtain good collocation knowledge for fluent and appropriate language use as many words are used in a limited set of collocations. Studies on cognitive linguistics show that cognitive factors play an important role in collocation study as most collocations are metaphorically motivated, and that collocational behavior is influenced by a number of factors, including the semantics of the individual items themselves, the influence of other well-established meanings, the influence of metaphor, the influence of semantic prosody, etc.. Therefore, it is significant to explain and teach certain types of collocations in language teaching by considering the underlying factors which influence the collocational process. Chinese English as a foreign language （EFL） learners have some special collocation problems in their English learning, which not only result from grammatical incompetence, but also from their lack of conceptual fluency and metaphor competence. The disclosure of similarities and differences between the conceptual systems of English and Chinese will help to illuminate the nature of negative transfer of their first language in collocation acquisition of Chinese EFL learners. The author of the paper, by disclosing the interaction between collocation and metaphor from cognitive, linguistic, and social perspectives, proposes semantic-oriented principle, pragmatics-oriented principle, and culture-oriented principle to incorporate cognitive factors to collocation teaching. It is suggested that stress should be given to the teaching of conceptual metaphor and its mechanisms in collocation teaching before students can finally improve collocation competence with a focus on metaphor awareness. 相似文献
