There was BMP4 expression at E10 in epithelium of otic capsule. Later, BMP4 expressions were affluent in condensed mesenchyme, vestibular cartilage capsule and sense epithelium. 3. The expression pattern of Smad4 in vestibule is different from BMP4. It was not conspicuous until E15 that Smad4 expressed in macula and crista ampullaris and until E16 in periotic cartilage capsule.

BMP4从E10开始，在间充质浓聚前就有表达；间充质一开始浓聚，BMP4在其中就有较丰富的表达；早期主要表达在前庭囊及前庭囊周围的间充质，在胚胎发育的后期，其在软骨囊及前庭上皮里有广泛阳性表达。3。

Because, begin from this period, the genitals of girls marked the beginning of the growth and maturing.

云南红豆杉胚珠从8月开始发生，大孢子母细胞12月开始发生，呈方形，减数分裂后形成4个"一"字形大孢子，在大多数情况下，只有靠合点端的大孢子发育为功能大孢子。

It's important to note that while puberty, in the form of early breast development, appeared to be starting sooner in the Danish girls, the average age of menarche, the time when girls begin menstruating, did not change as quickly.

值得指出的是当青春期，以早期乳腺发育的形式，似乎在丹麦女孩中开始更快，月经初潮的平均年龄，女孩开始月经的时间，并没有快速变化。

The protoxylem vessels initiated lignification in the early stage of vascular bundle differentiation, whereas metaxylem vessels and fiber walls started lignification from the middle lamella and cell comers after completion of vascular bundle differentiation. The walls of most parenchyma cells lignified after the stem reached its full height, while a few parenchyma cells remained non-lignified even the culm is 7 years old.

研究结果表明：毛竹茎的原生木质部导管在维管束发育早期就已木质化；后生木质部导管和纤维细胞在维管束分化完成后，自胞间层和细胞角隅处开始木质化；基本薄壁组织细胞木质化的发生较晚，通常在茎的节间完成伸长生长后才开始，但也有少数薄壁组织细胞始终保持非木质化的薄壁状态。

The call developmental process of Psittacula agapornis consists of five instinct phases according to its call character. In the first phase （congenital cal1 phase, CCP, 0~12 day of age）, the juveniles only produce single syllable with short syllable length. The second phase（blank-model-forming phase,BMFP, 13~30 day of age） is important for formation of vocal learning pathways. During this phase, the calls characterized by more and longer syllables. In the third phase （call-model-forming phase,CMFP, 31~45 day of age）, the call development is guided by a model system for vocal learning, vocal learning is engendered so that some calls with multi-syllables with UP1 are produced, principal frequency has increased about by 920 cent, the number of note is double that of second phase. The short-term memories are transformed into long-term memories in the forth phase （call-feedback-learning phase,CFLP, 46~90 day of age）. The call of juveniles is a close match to tutor call which accompanied by double various sounds with BS and UP1, and more resonance components were formed. Second principal frequency has increased about by 970 cent, the number of note increases by 2.6~3.0 times. During the fifth phase （excellent call phase,ECP, after 91 d）, vocal motor pathway is developed and the calls are accompanied with most stable, harmonious vari-tone and complex repertoire.

牡丹鹦鹉的鸣声发育分为5个时期。0~12 d为先天性鸣声期，鸣声特征为以基本音为主音的单音节单音调声，声长短。13~30 d为空白模板形成期，鸣声特征为以基本音为主音的多音节单音调声，声长和音量显著性增加，表明发声学习通路开始形成。31~45 d为鸣声模板形成期，鸣声特征为以第1陪音（UP1）为主音的多音节单变调声，声长和音量显著性增加，主音频提升约920音分，涵盖的律音数增加1倍，表明发声学习模板逐渐形成，发声学习开始。46~90 d为鸣声反馈学习期，鸣声特征为以BS和UP1为主音的双变调声，声长和音量显著性增加，主音频涵盖的律音数增加2.6~3.0倍，第2主音频提升约970音分，表明稳定模板逐渐形成，短期记忆逐渐向长期记忆转化。91 d后为完美鸣声期，鸣声特征为以UP1为主音的复合变音调声，声长、音量、主音频的提升和涵盖的律音数都趋于平稳，鸣声稳定而和谐，表明发声运动通路基本形成。

If confirmed, squints baby should be treated in time, most people visual development, three months from birth onwards, has been to continue until about 8 years old, including 2 children before the age of the critical period of visual development.

如果确认宝宝是斜视就应该及时治疗，一般人视觉发育，从出生3个月开始，一直可以持续到8岁左右，其中2岁以前是孩子视力发育的关键期。

First nymph will get into buds to feed germen by piercing-sucking mouthpart as soon as hatched, which stop flowering and make it becoming galls. From first to 3th nymph complete their development in flower-galls. They have a low death-rate since protection of galls. the 4th nymphs were observed in the end of July at the moment that the period of summer-diapause may begin.

孵化后的初龄若虫即进入未开放的花苞内以刺吸式口器取食子房，致使花苞不能开放而成为虫瘿。1—3龄若虫在花部虫瘿内完成发育，死亡率较低，至7月底发育到4龄若虫时开始夏滞育。

Result: Cafe au lait spots distributed girl's left cheek and left side of the back at birth; 4 years late, she appeared first vaginal bleeding, since 6 year old, her secondary sex characters developed, height growth acceleration; between 4 to 9 year old, she has occurred 5 times pathological bone fractures already; her menstrual cycle starts regularity from 9 year old, and when she was 10 year old, her serum E2 had reached the grown up woman level, but FSH and LH was normal. The B ultrasonic wave inspection demonstrated an ovary cyst at left side in pelvis cavity, X-ray picture of left thighbone conformed to the fibrous dysplasia.

结果：患儿出生时左脸颊和背部左侧多处咖啡牛乳斑；4岁首次阴道流血，6岁开始第二性征发育，生长加速；4~9岁曾5次病理性骨折；9岁起月经周期规则；10岁时血清雌二醇已达成人水平，促黄体生成素和促卵泡生成素正常；B型超声波检查曾显示盆腔左侧卵巢囊肿；左股骨X线片报告符合骨纤维发育不良征象。
