目的 了解新生儿先天性心脏病的患病情况,为制定和采取干预措施提供依据。方法 对2015年10月—2016年9月分娩的5 769名新生儿进行心脏彩超检查,根据筛查结果进行统计分析。结果 共筛查出182例新生儿先天性心脏病,患病率3.15%,先天性心脏病新生儿中女婴比例较高,差异边缘显著,早产儿比例较高,差异有统计学意义,产母年龄和正常组分布相近。先天性心脏病类型中室间隔缺损和房间隔缺损的构成比分别排第一位(48.90%)和第二位(38.46%),严重先天性心脏病仅占5.43%。结论 新生儿先心病的发病率较高,采用心脏彩超筛查可尽早发现先心病患儿,同时需做好先心病患儿的随访工作,及时进行干预。
Objective To investigate the prevalence of neonatal congenital heart diseases (CHD) and providing basis for integrating efficient interventions. Methods The color Doppler echocardiography screening were applied to 5 769 newborns from Oct 2015 to Sep 2016, and the data was collected and analyzed. Results 182 cases of neonatal CHD were detected, and the prevalence rate of neonatal CHD was 3.15%. The proportion of girls and premature infants in the newborns with CHD was significantly higher than normal newborns, but the age distribution of their mothers was similar. In the 182 CHD cases, ventricular septal defect(48.90%) and atrial septal defect(38.46%) accounted for the most, while the constituent ratio of severe CHD was only 5.43%. Conclusion The prevalence of neonatal CHD was relatively high, and the color Doppler echocardiography screening could find out neonatal CHD earlier. The follow-up examinations and interventions should be conducted in time.
目的 观察表皮生长因子(EGF)在新生儿坏死性小肠结肠炎(NEC)患儿肠组织中的动态表达情况,探讨EGF在NEC病程中起到的保护作用。方法 选取15例NEC患儿行一期回肠造瘘手术治疗的回肠组织为实验组(NEC组),将以上15例NEC患儿行二期回肠封瘘手术治疗的回肠组织为对照组(封瘘组),采用免疫组织化学技术检测,通过光密度测算软件(IPP)分析回肠组织中的EGF表达。结果 EGF主要表达于肠壁黏膜层,少量表达于黏膜下层、肌层。EGF在NEC组各层表达平均光密度值为:黏膜层(0.241±0.075),黏膜下层(0.213±0.061),肌层(0.1397±0.026),差异有统计学意义(P＜0.05);在封瘘组各层表达情况为:黏膜层(0.211±0.028),黏膜下层(0.119±0.022),肌层(0.097±0.007),差异有统计学意义(P＜0.05)。EGF在NEC组总体表达平均光密度值为(0.198±0.071),明显高于封瘘组(0.146±0.058),差异有统计学意义(P＜0.05)。结论 表皮生长因子(EGF)在新生儿坏死性小肠结肠炎(NEC)肠组织中的表达较封瘘组显著上调,推测EGF可能与NEC炎症相关,可能在NEC炎症过程中起到了一定的保护作用。
Objective We realized that EGF could play an important protective role against NEC. However, the practical condition of the distribution and expression of EGF in intestine of infants with NEC was indefinite. In order to figure out this problem,we carried out this experimentation. Methods The sample were divided into two group.The experimental group(necgroup) were composed of fifteen individual intestinal tissues after the ileostomy were performed on those infants suffered from NEC. The control group(sealing fistula group) were composed of fifteen individual intestinal tissues after the ileal closure fistula were performed on the same infants who were accepted the one-stage ileostomy in the period of NEC and were later accepted the two-stage operation on the condition that their bodies almost recovered from NEC after two to three months gone.Then, we utilized immunohistochemistry to test the distribution and quantities of EGF on those samples of the two group infants. Results The characteristic of EGF expression in intestine of the both group included strong positive expression in mucous layer and less expression in strata submucosum and muscular coat. The average optical density in nec group was mucous layer (0.241±0.075),strata submucosum(0.213±0.026),muscular coat (0.1397±0.022);In the control groupmucous layer (0.211±0.028),strata submucosum (0.119±0.022),muscular coat (0.097±0.007). The expression of EGF in intestinal tissues increased in the period of NEC0.198±0.071 by comparing with the control group (0.146±0.058). Conclusion There may be a correlation between the strong positive expression of EGF in intestinal tissues in the period of NEC and inflammation.By combining the result of this experiment and the research about EGF. We assumed that EGF is one factor of the protective mechanism by which injured intestinal mucous could be recovered and resist inflammation.

Early diagnosis and treatment should be as soon as possible to reduce fatalities.
目的 探讨神经元型一氧化氮合酶（nNOS）在抑制剂N-硝基-左旋精氨酸甲酯（L-NAME）抑制作用下与新生鼠胃肠道疾病的相关性研究，以进一步研究婴儿肥厚性幽门狭窄（IHPS）等疾病的致病机制。方法 对40只成熟雌性wistar大鼠随机均分4组，怀孕后予怀孕母鼠灌胃，对照组给予生理盐水，低剂量组、中剂量组、高剂量组分别给予L-NAME 60、300、600 mg/（kg·d）L-NAME。新生鼠皮下注射方式，予对照组皮下注射生理盐水，在低剂量组、中剂量组、高剂量组皮下注射L-NAME 25、125、250 mg/（kg·d）L-NAME。统计分析新生鼠幽门中的nNOS表达量、体质量增长情况、胃潴留情况、幽门肌层厚度。结果 （1）低剂量组、中剂量组、高剂量组新生鼠幽门肌层厚度在出生后第1、7、14日龄高于对照组，但组间比较差异无统计学意义（P＞0.05）。（2）与对照组相比，低剂量组、中剂量组、高剂量组的新生鼠出生后第1周体质量增加量更少，胃潴留更明显（P＞0.05）；在出生后的第2周各组体质量增加量差异无统计学意义（P＞0.05）。（3）新生鼠出生后第14天，中剂量组的胃体积大于低剂量组，但低剂量组和对照组之间、中剂量组和高剂量组之间比较差异无统计学意义（P＞0.05）。（4）新生鼠生后第1天，幽门中nNOS的表达被L-NAME以剂量依赖的方式被抑制，随着新生鼠日龄的增长，这种效应逐渐消失。（5）在不同剂量L-NAME的作用下，新生鼠幽门中nNOS表达量、趋势在不同时间点不同。结论 （1）nNOS可以导致新生鼠胃潴留、幽门梗阻，与IHPS相关症状之间存在相关性，但可能不是IHPS病因的唯一分子机制。（2）在新生鼠胃、幽门组织中，nNOS的表达量可以通过负反馈调节机制调节。（3）nNOS表达量上调可能有助于幽门舒张，但可能无法完全逆转IHPS中幽门的进一步肥厚和阻塞。
Objective To explore the effect of nNOS on the early postnatal pylorus of neonatal rats under the inhibition of the inhibitor N-nitro-L-arginine methyl ester hydrochloride（L-NAME），in order to further investigate the pathogenic mechanism of infantile hypertrophic pyloric stenosis（IHPS）．Methods Pregnant female mice were grouped randomly and administered by gavage，with the control group receiving physiological saline，the low-dose，medium-dose and high-dose groups receiving different doses of L-NAME．For the neonatal rats，the control group was subcutaneously injected with physiological saline，while the low-dose group，medium-dose group，and high-dose group were subcutaneously injected with different doses of L-NAME．The expression of nNOS in the pylorus，weight gain，gastric retention，and pyloric muscle thickness of newborn rats were statistically analyzed．Results (1) The thickness of the pyloric muscle layer in the low-dose group，medium-dose group，and high-dose group of newborn rats was higher than that in the control group on the 1st，7th，and 14th day after birth，but there was no significant difference．（2）Compared with the control group，the neonatal rats in the low-dose group，the middle-dose group and the high-dose group gained less weight in the first week after birth，and the gastric retention was more significant．There was no significant difference in weight gain among the groups in the second week after birth．（3）On the 14th day after birth，the gastric volume of the medium-dose group was larger than that of the low-dose group，but there was no statistical difference between the low-dose group and the control group，or between the medium-dose group and the high-dose group．（4）On the first day after birth，the expression of nNOS in the pylorus of neonatal rats was significantly inhibited by L-NAME with dose-dependence，and this effect gradually disappeared with increasing age of neonatal rats．(5) Under the action of different doses of L-NAME，the expression level and trend of nNOS in the pylorus of neonatal mice vary at different time points．Conclusions (1) nNOS can cause gastric retention and pyloric obstruction in newborn rats，which is related to IHPS related symptoms，but may not be the only molecular mechanism of IHPS etiology．(2) The expression level of nNOS in the pyloric tissue of newborn mice can be regulated through a negative feedback regulatory mechanism．(3) Upregulation of nNOS expression may contribute to pyloric dilation，but may not completely reverse thickening and obstruction of the pylorus in IHPS．
