Objective To analyze the clinical characteristics,perinatal high-risk factors and prognosis of neonatal Streptococcus agalactiae（group B Streptococcus,GBS）sepsis,and to improve the clinical understanding of Streptococcus agalactiae sepsis．Methods Twenty-one newborns with GES sepsis were selected（the cases were collected from February 2018 to November 2021）,and the clinical data were analyzed by retrospective investigation．The clinical data,laboratory examination and imaging data of newborns were summarized and compared,and the clinical characteristics were analyzed．At the same time,the complications of children were compared and the prognosis of treatment was evaluated．Results In newborns with GBS sepsis,the early-onset rate（90.48%）was significantly higher than the late-onset（9.52%）,P < 0.05．The main symptoms of newborns with GBS sepsis were shortness of breath,moaning,fever,cyanosis,convulsions,etc．Through laboratory examination,it was found that there were common abnormalities in C-reactive protein,procalcitonin,leukocyte count and other indicators in children．Transcranial MRI results showed 6 cases with subarachnoid hemorrhage;X-ray showed 6 cases with neonatal aspiration syndrome and 4 cases with both lungs neonatal pneumonia．Some children had complications,including 1 case with meningitis,3 cases with subarachnoid hemorrhage,4 cases with jaundice,and 2 cases with neonatal hypoglycemia．All children were treated with antibiotics,mainly penicillin and ceftazidime．The average hospital stay was（14.86 ± 2.33）days,and 19 cases were cured（accounting for 90.48%）．One case of the child's family member asked to sign and leave the hospital after improvement,and one case of the family member asked to be transferred to a superior children's hospital．Conclusions Neonatal Streptococcus agalactiae sepsis can be divided into early-onset and late-onset type．There are significant differences in clinical manifestations and characteristics between them．The disease is dangerous,clinical attention should be paid to the prevention and treatment of the disease,early diagnosis and timely treatment and intervention,so as to improve the prognosis of newborns．

目的 研究碳氧血红蛋白在新生儿ABO溶血病中的诊断价值。方法 将患者分为三组,选取144例足月新生儿ABO溶血病患儿为溶血组(A组),选取同期160例不合并溶血的足月黄疸新生儿为非溶血性黄疸组(B组),同时与88例足月健康新生儿(C组)对比。分析三组间碳氧血红蛋白、总胆红素、红细胞计数等有无差异。结果 溶血组患儿的碳氧血红蛋白水平较健康新生儿高,两组间差异有统计学意义(P＜0.001)。同时,溶血组患儿的碳氧血红蛋白水平较非溶血性黄疸组患儿高,两组间差异有统计学意义(P＜0.001)。碳氧血红蛋白在非溶血性黄疸组和健康新生儿组无统计学差异。碳氧血红蛋白ROC曲线值为1.27%时诊断新生儿ABO溶血病的敏感度和特异度最高(分别为90%和70%,P＜0.001)。溶血组患儿总胆红素水平与碳氧血红蛋白呈正相关关系(r=0.83523,P＜0.001),非溶血性黄疸患儿总胆红素水平与碳氧血红蛋白无相关性(r=0.12571,P＞0.05),溶血组患儿组总胆红素水平低于非溶血性黄疸患儿,而碳氧血红蛋白水平高于非溶血性黄疸患儿(P＜0.001)。结论 碳氧血红蛋白对新生儿ABO溶血病的诊断有临床意义,同时碳氧血红蛋白检测可作为体内胆红素产生量的指标,其有助于黄疸病因的鉴别、诊断及治疗。

Objective To explore clinical significance of determination of carboxyhemoglobin in ABO hemolytic disease of the newborn. Methods A total of 392 cases were randomly selected in the study. The experiment consisted of three groups: a total of 144 newborns consecutively hospitalized with ABO hemolysis were treated as experimental group(Group A); 160 newborns with hyperbilirubinemia and without hemolysis were collected(Group B); and 88 healthy newborns at term were the control group(Group C). Carboxyhemoglobin, serum total bilirubin and hemoglobin was collected and were compared with in the three subgroups. Results Compared with group C, carboxyhemoglobin were higher in ABO hemolytic disease(P<0.001). Compared with group B, carboxyhemoglobin were higher in ABO hemolytic disease(P<0.001), while carboxyhemoglobin showed no significant difference between group B and C (P>0.05). A carboxyhemoglobin cut-off value of 1.27% had 90% sensitivity and 70% specificity for predicting prescription. There was a positive correlation between total bilirubin level and carboxyhemoglobin level in newborns with ABO hemolysis(r=0.83523,P＜0.001). Conclusion Carboxyhemoglobin indicates the procedure of ABO hemolytic disease of the newborn, which is helpful to diagnose the cause of hyperbilirubinemia and taken as a guide in therapy.

目的 探讨新生儿高促甲状腺素血症转归与先天性甲状腺功能减低的相关性。方法 选择2014年4月—2015年4月在本院新生儿疾病筛查中心筛查并诊断为高促甲状腺激素血症的患儿120例,期间密切监测甲状腺功能指标变化。结果 将非治疗组所有患儿按照入组该实验后首次抽取静脉血TSH检测水平分为3组:5.5~10.0 mU/L(20例)、10.1~15.0 mU/L(10例)、＞15.0 mU/L (8例)。非治疗组患儿第2次随访结果显示5.5~10.0 mU/L组所有患儿TSH水平<10.0 mU/L;10.1~15.0 mU/L组有1例患儿TSH水平＞10.0 mU/L,FT4水平在正常值上限;＞15.0 mU/L组有3例患儿 TSH水平＞10.0 mU/L,差异有统计学意义(P< 0.05),FT4水平在正常均值左右,差异没有统计学意义(P＞ 0.05),＞15.0 mU/L组3例患儿给予左旋甲状素钠治疗。治疗组有2例患儿分别在治疗15天和23天后出现医源性甲状腺功能亢进,停药和酌减药量后TSH、FT4水平均恢复正常。两组患者随访结束后TSH、TF4均恢复至正常水平。结论 大多数新生儿高促甲状腺素血症会随着年龄的增长恢复正常,而仅仅有少部分患儿会持续出现甲状腺功能异常,应积极随访;新生儿只有当TSH 基础值＞15.00 mU/L时才需要采用左旋甲状素钠替代治疗,并且严格随访甲状腺功能,避免过度治疗。

目的 研究低Apgar评分新生儿外周动脉(非脐动脉,以下同)血pH对新生儿窒息诊断的作用。方法 选取本院出生Apgar评分1min≤7分活产婴儿158例,复苏后1 h内,平均(33±3.9)min,抽取外周动脉血气,分析其pH与Apgar评分及多器官损害关系,以探讨它们之间作为窒息诊断的互补性。结果 复苏后的外周动脉血pH值比脐动脉血pH值高,动脉血pH与Apgar 评分呈正相关。1min Apgar评分4～7分组中pH＞7.25者占67%(109/158),且几乎在5min时Apgar评分转至8分以上,提示可能没酸中毒或窒息。动脉血pH在7.25以下或1min Apgar评分0～3分者发生多器官损害率较高,而4～7分者且pH＞7.25时多器官损害率较低。与目前窒息的诊断标准对比,本组符合率降低,可能与采用复苏后的外周动脉而非脐动脉血pH有关。结论 外周动脉血pH一定程度上可反映窒息情况,低Apgar评分不等同窒息,动脉血pH及多器官损害是判断低Apgar评分新生儿是否窒息的重要互补因素,采用复苏后才抽取的外周动脉血pH判断窒息时,如果仍以pH＜7.20为标准,可能会造成漏诊。

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.

Objective To explore the influencing factors of hearing loss in newborns. Methods through screening, screening, diagnostic evaluation of 3 procedures to collect hearing loss in children, with 1:2 matching test and multivariate Logistic regression analysis in screening neonatal hearing loss risk factors. Results 20,661 cases of hearing loss in newborn screening, screening pass rate 88.99% (18386/20661); 2231 cases were re-screened for rescreening pass rate 96.51% (2153/2231); 78 patients who did not pass for rescreening ABR examination, diagnosed 59 cases of hearing loss, hearing loss incidence rate 2.86 ‰.
