Objective To explore the correlation between helicobacter pylori infection and children allergic purpura disease and its prognosis, and provide some basis for clinical diagnosis and treatment. Methods A total of 90 children with allergic purpura who were treated in our hospital from December 2016 to Feb 2018 were randomly selected as observation group. 90 healthy children who were admitted to our hospital for physical examination during the same period were selected as the control group, and the Hp infection in the two groups was compared. According to Hp infection and treatment, the observation group was divided into three groups: A, B and C, among which group A (29 cases) was Hp (-) group, and routine treatment was performed.Group B (31 cases) were Hp (+) group, and routine treatment was performed. group C (30 cases) were Hp (+) group, and conventional treatment combined with anti-hp treatment were performed. We compared three groups of .curative effects. Results The positive rate of Hp infection in the observation group was higher than that in the control group, and the difference was statistically significant (P<0.05).The positive rate of Hp infection in HSP patients with abdominal symptoms was higher than that in HSP patients without abdominal symptoms, and the difference was statistically significant (P<0.05). The effective rate of treatment in group B was significantly lower than that in group A, and the effective rate of treatment in group C was higher than that in group B, and the difference was statistically significant (P<0.05). Conclusion Hp infection may be one of the causes of HSP, and its abdominal symptoms are closely related to Hp, and the eradication of Hp treatment would improve the prognosis of HSP patients.

Objective To compare the clinical efficacy of bronchoalveolar lavage and conventional treatment in patients with severe pulmonary infection. Methods 92 patients with severe pulmonary infection treated in our hospital from May 2015 to April 2017 were selected as research objects. They were randomly divided into experimental group (n=46) and control group (n=46). The control group was treated with conventional symptomatic treatment, The experimental group implemented bronchoscopy lung lavage treatment. After treatment, blood gas bronchoscopic airway lavage in two groups were detected with analysis indexes. Serum inflammatory factors were determined by ELISA, and the serum levels of stress hormones were determined by radioimmunoassay. Results After the treatment, the PaO₂, SaO₂ and PaCO₂ in the experimental group were higher than those in the controlgroup(P<0.05). The levels of serum inflammatory factors hs-CRP, IL-6、IL-8 in the experimental group were lower than those in the control group (P<0.05); in addition, the levels of Ang-II, NE and Cor in the experimental group were lower than those in the control group(P<0.05). Conclusion Bronchoscopy airway lavage may help to improve the pulmonary ventilation function of patients with severe pulmonary infection, reduce the degree of systemic inflammatory stress, and promote disease recovery.

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.

Objective To describe the epidemiological characteristics of invasive group B streptococcal (GBS) infection among infants during the past 4 years in Guangzhou, in order to provide scientific basis for the prevention and control of the disease. Methods Medical records of infants with invasive GBS infection from two tertiary hospitals in Guangzhou from January 2012 to December 2015 were reviewed. Results There were 120 infants with invasive GBS infections during the past 4 years in two tertiary hospitals, the number of patients increased from 2012 to 2015, and the occurrence of infectionshad no obvious seasonal tendencies. Among infants with EOD, the most common syndrome was sepsis complicated pneumonia (46.3%), respiratory sign and at least one of perinatal risk factors were commonly recorded, and the mortality rate was 7.4%. By contrast, a higher proportion of late-onset cases manifested as sepsis associated with meningitis (42.4%), fever was the most common presentation and 42% LOD cases accompanied by neurological symptoms, 14.6% infants had neurological sequelae. Conclusion The number of GBS-infected infants increased during the past 4 years in Guangzhou. Relevant departments should pay attention to the prevention of neonatal GBS infection, strengthen the management of high risk newborns to improve the prognosis.

Objective To explore the relationship between helicobacter pylori infection and reflux esophagitis. Methods 364 patients with reflux esophagitis were enrolled in our hospital from Jan to Dec in 2010.The severity grade of reflux esophagitis was according to Los Angles standard. All the patients received biopsies from gastric antrum,then received pathologic examinations. Results Reflux esophagitis in men was more common, with an average age of onset earlier than the female(52.4±11.6 years vs 56.6±12.4 years,P=0.002);Reflux esophagitis in patients with H.pylori infection rate was 90.9% overall,mainly with mild infection,four groups of H.pylori infection rate and extent of infection was no significant difference (P values were 0.419,0.702);reflux esophagitis in patients with chronic superficial gastritis(CSG),moderate active inflammation based was more common,there was no statistically significant difference in four group(P values were 0.146,0.496). There was no significant difference between H.pylori positive patients and H.pylori negative patients in esophageal mucosal damage(P> 0.05). There was no significant difference in reflux esophagitis with varying degrees of H.pylori infection on the degree of esophagitis. Conclusion Four groups of H.pylori infection rate and extent of infection was no significant difference; there was also no significant difference between H.pylori positive patients and H.pylori negative patients in esophageal mucosal damage. There was no significant difference in RE with varying degrees of H.pylori infection on the degree of esophagitis. Our research showed H.pylori infection had no relationship with degree of RE.
