对438名3~6岁儿童乳牙患龋情况与母亲妊娠情况及出生后第1a喂养方式的关系进行了调查。结果:母亲病理性妊娠的被调查儿童乳牙患龋率、乳牙龋均明显高于母亲生理性妊娠的儿童(分别为80.91%>69.54%,5.00>3.06,P<0.05);母亲为生理性妊娠,出生后第1a内人工或混合喂养的儿童乳牙患龋率、乳牙龋均、龋并发症发生率都明显高于母乳喂养6个月以上的儿童(分别为73.77%>62.67%,3.59>2.20,13.33%>6.38%,P<0.05);母亲有病理性妊娠,出生后第1a内人工或混合喂养的儿童乳牙患龋率、乳牙龋均明显高于母乳喂养6个月以上的儿童(分别为84.42%>74.71%,5.64>3.89,P<0.05),但2组的龋并发症发生率都较高(分别为24.62%,23.08%)。提示:母亲病理性妊娠和婴儿出生后第1a人工或混合喂养对乳牙患龋率、乳牙龋均、龋病程度及龋并发症的发生均有不利影响,为制定切实可行的乳牙防龋措施提供了依据 The relationship between deciduous teeth caries in 438 children aged 3 ~ 6 years and their mothers' pregnancy and their feeding patterns after birth was investigated. Results: The caries prevalence rate and deciduous caries of mothers with pathological pregnancy were significantly higher than that of maternal physiological pregnancy (80.91%> 69.54%, 5.00> 3.06, P < 0.05). The rate of caries in deciduous teeth, caries in deciduous teeth and caries in mothers who were mothers with physiological pregnancy and were fed artificially or mixedly within the first year after birth were significantly higher than those of children breastfeeding for more than 6 months 73.77%> 62.67%, 3.59> 2.20, 13.33%> 6.38%, P <0.05). The mothers had pathological gestations, and artificial or mixed The prevalence of decayed caries in deciduous teeth and caries in deciduous teeth were significantly higher than those in breastfeeding children over 6 months (84.42%> 74.71%, 5.64> 3.89, P <0.05, respectively) However, the incidence of caries complications in both groups were higher (24.62% and 23.08%, respectively). It is suggested that maternal pathological pregnancy and postnatal day 1a artificial or mixed feeding have adverse effects on the caries prevalence of deciduous teeth, the degree of deciduous caries, the degree of cariousness and the occurrence of caries complications, so as to provide feasible deciduous deciduous caries prevention measures The basis

多年以来语文的阅读和写作教学一直处于低效状态,阅读与写作分离,是语文课堂教学的普遍现象。因此,教师在使用教材时要融入自己的经验和智慧,对教材进行增删、选择和重组,在保证阅读的认识、教育、审美等基本功能的同时,兼顾学生学习语言、训练写作的要求。这样,凭借课文的例子,运用语文这个工具,由间接吸收到直接表达,循序渐进,循环往复,螺旋上升,就能达到“源头活水奔涌而来”的境界,开创语文教学的崭新局面。

气体的实验室制法将基本操作和理论知识融合在一起,具有全面考查化学素质的功效,是历年中考化学的热点。研究气体的实验室制法应考虑以下三个方面:一、反应原理;二、实验装置;三、气体验证。在具体实验中涉及药品和仪器的选择、装置的连接、气密性检查、实验先后顺序、验证方法、收集方法以及对实验现象或结果作出分析等内容。我们在熟练掌握O和CO的实验室制法的同时,要触类旁通,灵活运用所学知识解决其他气体的制备问题。
