目的 探讨益生菌辅助治疗儿童过敏性哮喘的临床疗效，分析其对Th1/Th2免疫失衡、炎症反应、免疫功能及复发风险的影响。方法 选取2022年1月至2023年12月本院收治的80例过敏性哮喘患儿，按随机数字表法分为对照组和观察组，各40例。对照组接受常规抗哮喘治疗（布地奈德雾化吸入+孟鲁司特钠），观察组结合益生菌进行辅助治疗。比较两组肺功能[第1秒用力呼气容积占预计值百分比（FEV1%）、最大呼气峰流速占预计值百分比（PEF%）]、Th1/Th2细胞因子[干扰素-γ（IFN-γ）、白细胞介素-4（IL-4）、白细胞介素-13（IL-13）]以及治疗总有效率、治疗后6个月内复发率。结果 治疗后，观察组FEV1%、PEF%分别为（87.35±5.21）%、（85.62±4.93）%，高于对照组的（78.44±5.67）%、（76.18±5.20）%（P<0.05）。观察组IFN-γ为（32.58±4.12）pg/mL，高于对照组的（24.36±3.89）pg/mL（P<0.05）；IL-4、IL-13分别为（18.27±3.06）pg/mL、（22.14±3.51）pg/mL，低于对照组的（25.63±3.74）pg/mL、（31.05±4.02）pg/mL（P<0.05）。观察组治疗总有效率为92.50%（37/40），高于对照组的75.00%（30/40）（P<0.05）。随访6个月，观察组哮喘复发率为10.00%（4/40），低于对照组的27.50%（11/40）（P<0.05）。结论 益生菌辅助治疗儿童过敏性哮喘可显著改善肺功能及临床症状，调节Th1/Th2免疫失衡，提高临床疗效，并降低复发风险，值得临床推广。

目的 研究益生菌结合肠内营养(enteral nutrition,EN)干预纠正缺血急性脑梗死(acute cerebral infarction,ACI)患者肠道菌落紊乱的作用及对患者预后的影响。方法 将97例无法自主进食的ACI患者根据治疗方法不同分为观察组(采用益生菌结合EN进行营养支持)和对照组(单纯EN为营养支持)进行治疗,疗程30 d,比较2组肠道菌落生长情况、患者营养水平、临床疗效及预后。结果 治疗后,2组双歧杆菌、肠球菌、大肠杆菌数量先降低后升高,2相邻时间点之间差异显著(P<0.05),2组乳酸杆菌数量持续升高,观察组各时间点之间差异显著(P<0.05),对照组治疗第7 d开始有明显差异(P<0.05),且治疗第7 d后观察组双歧杆菌、肠球菌、大肠杆菌数量高于对照组,差异有统计学意义(P<0.05),治疗第14 d后,观察组乳酸杆菌数量高于对照组,差异有统计学意义(P<0.05);治疗后,观察组体质量指数(body mass index,BMI)、肱三头肌皮皱厚度(triceps skinfold thinkness,TSF)、上臂肌围(arm muscle circumference,AMC)及血红蛋白(hemoglobin,HB)明显降低(P<0.05),对照组BMI、TSF、AMC、HB、白蛋白(albumin,ALB)及三酰甘油(triglyceride,TG)均明显降低(P<0.05),且观察组BMI、TSF、AMC、HB、ALB及TG高于对照组,差异有统计学意义(P<0.05);观察组治疗过程中腹胀、腹泻发生率低于对照组,差异有统计学意义(P<0.05);治疗后2组APACHEⅡ评明显降低(P<0.05),且观察组APACHEⅡ评分低于对照组,差异有统计学意义(P<0.05);治疗后观察组日常生活活动能力(activities of daily life,ADL)评分高于对照组,ADL分级优于对照组,差异有统计学意义(P<0.05)。结论 益生菌结合EN治疗可有效纠正患者肠道菌落平衡,保护胃肠道功能,从而改善机体营养水平,提高ACI治疗效果,改善患者预后。

目的 探讨含双歧杆菌乳杆菌三联活菌新四联疗法对消化性溃疡患者幽门螺杆菌(Helicobacter pylori, Hp)根除治疗中的疗效。方法 将342例Hp阳性的消化性溃疡患者随机分为三个治疗组:A组(三联疗法)、B组(含铋剂四联疗法)及C组(含益生菌四联疗法),疗程均2周。疗程结束4周后复查¹³C-尿素呼气试验评估根除疗效。治疗期间记录患者不良反应发生情况。结果 300例(87.72%)患者按方案完成治疗,A、B及C组治疗完成率分别为85.71%(96/112)、82.50%(99/120)和95.45%(105/110),C组显著高于A及B组(P＜0.05)。在胃溃疡Hp根除率比较中,按意愿(方案)分析,A、B及C组疗法的Hp根除率分别为64.71%(75.86%)、71.43%(85.71%)及84.38%(87.10%),各组间差异无统计学意义(P均>0.05)。在十二指肠球部溃疡Hp根除率比较中,按意愿(ITT)分析,C组(85.90%)明显高于A组(62.82%)及B组(71.79%),差异有统计学意义(χ²=10.893,P=0.001;χ²=4.650,P=0.031);按方案(PP)分析,B组(87.50%)与C组(90.54%)明显高于A组(73.13%),差异有统计学意义(χ²=4.246,P=0.039;χ²=7.304,P=0.007),但B组与C组之间差异无统计学意义(P<0.05)。胃肠道不良反应中,便秘、味觉异常及腹胀的发生率,含益生菌疗法组明显少于另两组,差异有统计学意义(P均<0.05)。结论 含双歧杆菌乳杆菌三联活菌新四联疗法能够显著降低传统三联及四联根除疗法的胃肠道不良反应,提高患者依从性,从而提高消化性溃疡患者Hp的根除率。

Objective To investigate the efficacy of quadruple therapy containing bifidobacterium and lactobacillus triple live bacteria on eradication of Helicobater pylori (Hp) among the patients with peptic ulcer. Methods 342 Hp-infected peptic ulcer patients were randomly divided into three groups:A, B and C. The patients in group A were treated with standard triple therapy. The patients in group B and group C were treated with Colloidal Bismuth Subcitrate and Bifidobacterium and Lactobacillus combined with standard triple therapy, respectively. All patients in three groups were treated for 14 days. In the 4th week after end of treatment, Hp eradication was assessed by ¹³C-urea breath test. Adverse effects during the course of treatment were recorded. Results A total of 300(87.72%) patients completed the treatment. The completion rates in group A, B and C were 85.71%(96/112), 82.50%(99/120) and 95.45%(105/110) respectively, and the completion rate in group C were significantly higher than that in group A and group B(P<0.05). With intention to treat and per-protocol analysis in gastric ulcer, the eradication rates of group A, B and C were 64.71%(75.86%), 71.43%(85.71%)and 84.38%(87.10%) respectively, but there were not significant difference in the three groups(P>0.05). With intention to treat analysis in duodenal ulcer, the Hp eradication rate in group C was 85.90%, which was significantly higher than that in group A (62.82%;χ²=10.893,P=0.001) and in group B (71.79%;χ²=4.650,P=0.031). With per-protocol analysis in duodenal ulcer, the Hp eradication rate was 90.54% in group C and 87.50% in group B. No Obviously difference was found between group B and group C (P<0.05), but both were higher than that in group A(73.13%) (χ²=4.246,P=0.039;χ²=7.304,P=0.007). The incidence of adverse reactions including constipation, taste distortion and bloating in group C were significantly lower than those in the other two groups (P<0.05). Conclusion The quadruple therapy containing bifidobacterium and lactobacillus triple live bacteria can obviously enhance the patient's compliance and decrease the adverse reactions, thereby may increase the Hp eradication rate among the patients with peptic ulcer.
