目的 探讨分析氨茶碱治疗早产儿呼吸暂停的临床疗效及其在治疗过程中所出现的不良事件。方法 选取2014年9—2016年3月广州市第一人民医院新生儿科接受住院治疗的胎龄＜34周,生后2 h内入住新生儿科的早产儿42例。随机分为对照组和氨茶碱组,对照组(20例)给予保暖、吸氧、补充能量、保持呼吸道通畅、物理刺激等对症治疗,不使用氨茶碱及其它改善呼吸的药物;氨茶碱组(22例)患儿除给予对照组治疗措施外,同时给予氨茶碱静脉滴注,首剂负荷量5 mg/kg,在20min内完成,12 h后以2～2.5 mg/kg维持量,每隔12 h一次。观察两组的疗效与不良影响。结果 ①两组患儿性别、出生胎龄、出生体重、产前孕母糖皮质激素的应用、受孕方式、分娩方式、多胎妊娠、5min Apgar评分、机械通气及CPAP辅助通气例数、低-中流量吸氧(箱内或头罩给氧)例数等方面差异均无统计学意义(P均＞0.05)。②与对照组相比,氨茶碱组早产儿呼吸暂停(AOP)发生的次数较少,AOP消失所需时间较短,差异均有统计学意义(P＜0.05)。③不良影响方面,氨茶碱组脑白质发育不良发生率(63.6%,14/22例)显著高于对照组(25%,5/20例),差异有统计学意义(P＜0.05);两组患儿在听力检查异常、喂养不耐受、血糖紊乱、血脂代谢紊乱、血红蛋白下降、电解质紊乱、出院时体重及住院时间等方面均无统计学意义(P均＞0.05)。④氨茶碱组视网膜发育不完全的发生率(40.9%,9/22例)明显高于对照组(15.0%,3/20例),但差异无统计学意义(P＞0.05)。结论 小剂量氨茶碱在防治AOP方面的作用是值得肯定的,但它有可能增加早产儿脑白质发育不良的风险与视网膜发育不完全的风险。

Objective To investigate the clinical efficacy and adverse effects of aminophylline in prevention of apnea of prematurity. Methods Forty-two infants with gestational age ＜34 weeks admitted to department of pediatrics, Guangzhou first people's hospital between Sep. 2014 and Mar. 2016 were randomly divided into 2 groups: control group and aminophylline group. Control group(n=20): 20 infants received warming, oxygen inhalation, supplement energy, maintain airway patency, physical stimulation, such as symptomatic treatment, without aminophylline or any other drugs for improving breathing. Aminophylline group(n=22): In addition to the control group treatment measures, 22 infants received a loading dose of 5 mg/kg of aminophylline and then maintained by a dose of 2mg/kg with intravenous drip q 12 h. Then we compared the efficacy and adverse effects of the two groups. Results ①There was no significant difference in gender, gestational age, birth weight, maternal antenatal glucocorticoid application, pregnancy(including multiple pregnancy) and delivery,5 min Apgar score, oxygen therapy, the application of mechanical ventilation, nasal continuous positive airway pressure, and the low-medium flow oxygen inhalation between the 2 groups(all P＞0.05). ② Compared with the control group, the incidence of apnea in aminophylline group were significant lower, and the time needed for apnea to disappear were significant shorter(all P＞0.05). ③ The incidence of cerebral white matter development dysplasia of aminophylline group(63.6%,14/22 cases) were significant higher than the control group(25%,5/20 cases, P＜0.05). There was no statistically significant difference in hearing loss, feeding intolerance, blood glucose disturbance, blood lipid metabolism disorder, hemoglobin decrease, electrolyte disorder, body weight at discharge, the duration and cost of hospitalization between the 2 groups(all P＞0.05). ④ The incidence of retinal incompleted development of aminophylline group(40.9%, 9/22 cases) were higher than control group(15.0%, 3/20 cases), but there was no statistical significance between the 2 groups(P＞0.05). Conclusion Effects of aminophylline in treating apnea of prematurity is positive, but it is likely to increase the risk of premature brain white matter development dysplasia and the risk of retinal incompleted development.

Objective To investigate the clinical significance of combined detection of serum ferritin and high sensitive C reactive protein in patients with acute cerebral hemorrhage. Methods From January 2012 to December 2013, 77 cases with cerebral hemorrhage male 42, female 35; aged 45 to 82 year old, average age (67.19±10.17)years old. According to MRS(Modified Rankin Scale) score criteria, patients were divided into good prognosis group(group A) with MRS ≤2, and poor prognosis group (group B)with MRS ＞2. Another 35 cases of healthy physical examination were selected as the healthy control group(group C). RT(Routine blood test), Serum Ferritin(SF)and Hs-CRP were tested at the time of admission, the third, the seventh and the fourteenth day from onset of the disease respectively. Head CT were done at the time of admission, the third day from onset of the disease respectively. Neurological assessment were scored according to the NIHSS criteria(National Institutes of Health Stroke Scale) for the patients in the two groups at the time of admission and 12 months of follow up. Results 77 cases of cerebral hemorrhage were followed up for 12 months, 53 cases with MRS ≤2, the prognosis was good; And 24 cases with MRS >2, the prognosis was poor. The levels of Hs-CRP and SF were all higher in patients with cerebral hemorrhage than that in healthy control group (P<0.05) at the time of admission, the third day,seventh and fourteen day from onset of the disease respectively. The levels of Hs-CRP and SF were higher in group B than that in control group at the time of admission, the third day, the seventh day and the fourteenth day from onset of the disease respectively, but only at the time of admission, three days from onset of the disease, the difference was statistically significant (P<0.05). At the same time, the brain edema and edema index in the group B were higher than those in group A. The independent risk factors influencing the prognosis of cerebral hemorrhage were NIHSS score (P=0.012), Hs-CRP(P=0.027) and SF(P=0.041). Conclusion Hs-CRP and SF may be important indicators of the prognosis for cerebral hemorrhage in a certain degree.

Objective We analyzed the physical examination results of retired cadres,to acquaint the health status of the targeted population and provide the basis for the disease prevention and treatment. Methods Among the retired cadres who conducted healthy examination in the successive two years of 2014 and 2015, we selected 3841 cases of which examination items were the same in these two years. Based on their healthy examination results, we investigated the diseases of which detected rates of positive sign ranked in top 15, including the different appearances between different genders, and made comparisons with that of year 2014. Results Out of the top 15 diseases, senile cataract, hypertension and nodular goiter ranked in top 3. Compared with that of year 2014, a decrease of the detection rate could be seen in three diseases namely senile cataract, hyperuricemia and cholecystolithiasis, but an increase in five diseases namely nodular goiter, hemorrhoids, chronic pharyngitis, hyperlipidemia and cholecystitis. Conclusion Regular examination is an important way to acquaint the health status of retired cadres, and find pathogenesis risk factors timely. The healthy management however is still weak after physical examination.Thus it can be seen that healthy intervention has become increasingly urgent.

目的 通过对婴幼儿泌尿系感染并发脓毒症的临床特点、病原菌情况及相关因素的分析,探讨其早期诊断和及时治疗的措施。方法 选取83例我科收治的确诊泌尿系感染合并脓毒症的婴幼儿作为研究对象,回顾性分析其临床表现、实验室检查及治疗预后情况。结果 所选婴幼儿均确诊泌尿系感染合并脓毒症,以男性患儿多见,全身中毒症状重,6月以下多以严重脓毒症、脓毒性休克为首诊表现,尿路刺激症状不明显。有明显细菌感染生物标记物的改变。细菌学培养共检出细菌22株,大肠埃希菌占54.55% (12/22),对头孢吡肟较为敏感,对亚胺培南、美罗培南全部敏感;屎肠球菌占22.73%(5/22),对万古霉素、利奈唑胺、替考拉宁敏感。结论 在婴幼儿常见的感染部位中,泌尿系感染容易被忽略。而小于6月的患儿更易并发严重脓毒症、脓毒症休克等危重症。因此,以脓毒症为首诊表现的婴幼儿应特别警惕泌尿系感染,尽可能早期明确感染部位,防止漏诊。首诊1小时内给予广谱抗生素治疗,可降低婴幼儿脓毒症的病死率,改善患儿预后。

Objective By analyzing the clinical features, laboratory tests, pathogenic bacteria culture and the treatments of infants and toddlers with urinary tract infection UTI accompanied with sepsis, we aim to guide the further clinical treatments and prevention. Methods We selected 83 cases from January 1, 2014 to December 31, 2016 in our hospital as the research objects which were accepted the diagnosis and treatments of urinary tract infection complicated with sepsis. Its clinical manifestations, laboratory tests, bacteriology examination and treatment prognosis were retrospectively analyzed. Results Among the selected infants and toddlers diagnosed with urinary tract infection complicated with sepsis, male patients were more common. Symptoms of systemic poisoning were observed in the majority especially in the children aging under 6 months, with severe sepsis and septic shock as the first manifestation, while conventional symptoms were not obvious. Biological markers of bacterial infection were significantly changed. In bacterial culture, 22 strains of bacteria were detected, Escherichia coli accounted for 54.55% (12/22), were almost sensitive to cefepime, and all sensitive to imipenem and meropenem; Enterococcus following accounted for 22.73% (5/22), could be more sensitive to vancomycin, linezolid, teicoplanin. Conclusion Urinary tract infection is common in under 3 years old babies. Patients aging under 6 months are more likely to be complicated with severe sepsis and septic shock. Therefore, we should be especially vigilant of the UTI among the babies whose first manifestations appear to be sepsis only. It is important to find out the site of infection as early as possible, in order to prevent misdiagnosis. It is also critical to use broad-spectrum antimicrobial therapy within 1 hour when severe sepsis is diagnosed in order to reduce the mortality of sepsis in infants and improve the prognosis.
