Objective To analyze the clinical characteristics of the children with severe influenza B and to provide reference for identifying severe cases. Methods Clinical data of 7 children with severe influenza B were retrospectively analyzed. Results The age ranged from 11 months to 7 years old, with an average was (4.13±2.06) years old. Five cases were characterized by respiratory failure, one by cardiogenic shock and one by acute necrotizing encephalopathy. No leukopenia was observed at the beginning of the disease(in 3 days), and the number of white blood cells was as high as 28.1×10⁹/L, White blood cell classification is dominated by neutrophils. haemophilus influenzae and streptococcus pneumoniae were produced by sputum culture in 1 case for each. Three patients had plastic bronchitis changes. After active treatment, the body temperature returned to normal with minimum 2 days, longest 7 days and average (4.20+1.79)days. The length of stay was the shortest 12 days, the longest 23 days, and the average (16.71+3.90) days. Conclusion The clinical manifestations of severe influenza B are diverse and may involve multiple system organs. Respiratory complications were the most common, with plastic bronchitis changes. Early recognition and active treatment had a good prognosis.

目的 探讨儿童不明原因肝功能异常的临床特点、病因及预后,为临床及时对因治疗提供帮助。方法 回顾性分析本院2016年1月—2017年12月期间205例以不明原因肝功能异常住院患者的临床资料,并对其临床特点、病因及预后进行分析。结果 在205例不明原因肝功能异常患者中,其中166例(80.97%)得到明确诊断,涉及多种疾病。其中分别为非嗜肝病毒所致感染性肝损104例(50.73%),遗传代谢疾病38例(18.54%),药物性肝损11例(5.37%),全身性疾病如川崎病6例(2.93%)、血液肿瘤疾病4例(1.95%)、营养不良3例(1.46%)等,原因未明 39例(19.02%)。结论 引起肝功能异常病因多且复杂。婴幼儿肝功能异常以非嗜肝病毒所致感染性肝损为主,感染主要为巨细胞病毒及EB病毒;遗传代谢性疾病、药物性肝损、全身性疾病也是造成肝功能异常的重要原因。

Objective To investigate the clinical features, etiology and prognosis of children patients with unexplained liver dysfunction. Methods The clinical data of 205 inpatients with unexplained liver dysfunction from January 2016 to December 2017 were analyzed retrospectively. The clinical characteristics, etiology and prognosis were analyzed. Results Of 205 patients with unexplained abnormal liver function, 166 patients with liver dysfunction (80.97%) were clearly diagnosed and involved in a variety of diseases. Among them, 104 cases were infected liver damage caused by non-hepatophilic virus, 38 cases were related to genetic metabolic diseases, 11 cases were drug-induced liver damage, 6 cases were Kawasaki disease, 4 cases were hematologic tumor diseases, 3 cases were malnutrition. The cause of abnormal liver function was not clear in 39 cases. Conclusion There are many and complicated causes of abnormal liver function, and part of the causes are unknown. Infantile liver dysfunction was mainly caused by non-hepatophilic virus, the first was cytomegalovirus, the second was Epstein-Barr virus; genetic metabolic disease, drug-induced liver damage, systemic disease are also an important cause of liver dysfunction.

目的 探讨儿童登革热(DF)合并肝功能损害的临床特征。方法 对2014年8—12月我院感染科收治住院的78例儿童DF的临床资料进行回顾性分析。结果 并发肝功能损害36例(46.15%),其中血清丙氨酸转氨酶(ALT)升高24例(30.77%),血清天冬氨酸转氨酶(AST)升高33例(42.31%);27例(75%)ALT/AST病程2周内恢复正常,9例于1月复查恢复正常。仅有1例总胆红素(TBIL)升高80.8 μmol/L,直接胆红素升高为主,1周后恢复正常。肝功能损害组较无肝功能损害组在外周血白细胞水平、血小板水平差异有统计学意义(P<0.05)。结论 儿童DF并肝功能损害较普遍,以轻度损害为主。与年龄、性别、皮疹、外周血白细胞、血小板有相关性。

Objective To approach the clinical characteristics of children dengue fever combined liver function damage. Methods Clinical data of 78 cases of children dengue fever in our hospital were retrospectively analyzed from August to December in 2014. Results 36 cases (46.15%) complicated with liver function damage. Among them 24 cases (30.77%) of serum alanine aminotransferase (ALT) increased, 33 cases (42.31%) of serum aspartate aminotransferase (AST) increased; 27 cases (75%)ALT/AST returned to normal within 2 weeks, 9 cases were recovered to normal in 1 month. Only 1 cases of total bilirubin (TBIL) increased to 80.8 mol/L, recovered after 1 week. Liver injury group and non liver injury group of peripheral blood leukocytes, platelets level comparison was statistically significant (P<0.05). Conclusion Children dengue fever combined liver function damage was common, mainly mild. There was correlation with age, gender, skin rash, peripheral blood leukocytes and platelets.
