目的 探讨清咳平喘颗粒联合乙酰半胱氨酸对痰热闭肺型大叶性肺炎（LP）患儿的治疗效果。方法 回顾性选取我院收治的118例痰热闭肺型LP患儿（选例时间：2023年1月~2025年11月）为研究对象，根据治疗方案分为参照组（59例，采用乙酰半胱氨酸治疗）、联合组（59例，采用清咳平喘颗粒联合乙酰半胱氨酸治疗）。对比两组临床疗效、不良反应及治疗前、后肺功能［潮气量（VT）、达峰时间比（TPTEF/TE）、吸呼比（Ti/Te）、达峰容积比（VPEF/VE）］、中医证候、免疫功能、炎症因子［白细胞介素-8（IL-8）、趋化因子配体3（CCL3）、肿瘤坏死因子-α（TNF-α）、高迁移率族蛋白B1（HMGB1）］水平。结果 联合组总有效率为96.61%，高于参照组的83.05%（P＜0.05）；与参照组相比，治疗后联合组各中医证候积分均较低（P＜0.05）；联合组治疗后VT、TPTEF/TE、Ti/Te、VPEF/VE水平均较参照组高（P＜0.05）；联合组治疗后CD8+水平较参照组低，CD3+、CD4+、CD4+/CD8+水平较参照组高（P＜0.05）；治疗后联合组血清IL-8、CCL3、TNF-α、HMGB1水平均较参照组低（P＜0.05）；不良反应发生情况组间比较，无明显差异（P＞0.05）。结论 清咳平喘颗粒联合乙酰半胱氨酸可提高痰热闭肺型LP患儿治疗效果，减轻临床症状，改善肺功能、免疫功能，降低机体炎症反应程度。

Objective To explore the therapeutic efficacy of Qingke Pingchuan granules combined with acetylcysteine on children with lobar pneumonia (LP) of phlegm-heat obstructing lung type. Methods A total of 118 children with LP of phlegm-heat obstructing lung type admitted to our hospital from January 2023 to November 2025 were retrospectively selected as the research subjects. According to different treatment regimens, they were divided into the control group (59 cases, treated with acetylcysteine) and the combined group (59 cases, treated with Qingke Pingchuan granules combined with acetylcysteine). The clinical efficacy, adverse reactions, as well as the levels of pulmonary function indicators [tidal volume (VT), time to peak tidal expiratory flow ratio (TPTEF/TE), inspiration-expiration ratio (Ti/Te), volume to peak tidal expiratory flow ratio (VPEF/VE)], traditional Chinese medicine (TCM) syndrome scores, immune function and inflammatory factors [interleukin-8 (IL-8), C-C motif chemokine ligand 3 (CCL3), tumor necrosis factor-α (TNF-α), high mobility group box 1 protein (HMGB1)] before and after treatment were compared between the two groups. Results The total effective rate of the combined group was 96.61%, which was higher than 83.05% of the control group (P<0.05). After treatment, the TCM syndrome scores of the combined group were lower than those of the control group (P<0.05). The levels of VT, TPTEF/TE, Ti/Te and VPEF/VE in the combined group were higher than those in the control group after treatment (P<0.05). After treatment, the level of CD8? in the combined group was lower, while the levels of CD3?, CD4? and CD4?/CD8? were higher than those in the control group (P<0.05). The serum levels of IL-8, CCL3, TNF-α and HMGB1 in the combined group were significantly lower than those in the control group after treatment (P<0.05). There was no significant difference in the incidence of adverse reactions between the two groups (P>0.05). Conclusion The combination of Qingke Pingchuan granules and acetylcysteine can enhance the therapeutic efficacy on children with LP of phlegm-heat obstructing lung type, relieve clinical symptoms, improve pulmonary function and immune function, and reduce systemic inflammatory response.

目的 探究肺炎支原体（MP）感染大叶性肺炎患儿常规通气、脉冲振荡肺功能特点。方法 将2022年5月—2023年5月广州市妇女儿童医疗中心收治的90例MP感染大叶性肺炎患儿为观察组,通气体检健康儿童50例为对照组,依据病变将累及多肺叶作为观察A组（10例）,累及单肺叶作为观察B组（80例）。均接受常规通气与脉冲振荡肺功能测定,观察测定结果,以此为基础,分析肺功能特点。结果 观察组各常规通气肺功能指标测定结果均低于对照组健康儿童,差异有统计学意义（P<0.05）。观察组R5、R20的实测值/预计值高于对照组,X5实测值低于对照组,差异有统计学意义（P<0.05）。气道阻力指标与肺功能呈负相关关系（P<0.05）。观察组两组最大肺活量（VCMAX）、呼气流量峰值（PEF）、用力肺活量（FVC）75%、FVC50%、FVC25%的实测值/预计值差异无统计学意义,观察A组患儿FVC、FEV₁的实测值/预计值低于观察B组患儿,差异有统计学意义（P<0.05）。两组患儿脉冲振荡肺功能对比差异无统计学意义（P>0.05）。90例患儿中,常规通气异常患儿12例,患儿治疗前后VCMAX、FVC75%、FVC50%的实测值/预计值差异无统计学意义,患儿治疗前FVC、FEV₁、PEF、FVC25%的实测值/预计值均低于治疗后,差异有统计学意义（P<0.05）。结论 常规通气与脉冲振荡相关性良好,气道阻力对VCMAX及FVC具有反向作用,MP感染大叶性肺炎主要表现为小气道通气功能受损,气道阻力升高。

Objective To explore the lung function characteristics of routine ventilation and pulse oscillation in children with lobar pneumonia infected with Mycoplasma pneumoniae（MP）．Methods Ninety children with MP infected lobar pneumonia admitted to Guangzhou Women and Children's Medical Center from May 2022 to May 2023 were selected as the observation group,and 50 healthy children undergoing ventilation examination were selected as the control group．Based on the lesion,cases with multi lobar involvement were selected as the observation group A（10 cases）,cases with single lobar involvement were selected as the observation group B（80 cases）．All patients underwent routine ventilation and pulse oscillation received pulmonary function measurement,and the measurement results were observed．Based on this,the characteristics of lung function were analyzed．Results The results of routine ventilation lung function indicators in the observation group were lower than those in the control group,and the difference was statistically significant（P<0.05）．The measured/expected values of R5 and R20 in the observation group were higher than those in the control group,while the measured values of X5 were lower than those in the control group,with statistical significance（P<0.05）．There is a negative correlation between airway resistance indicators and lung function（P<0.05）．The measured/predicted values of vital capacity max（VCMAX）,peak expiratory flow（PEF）,forced vital capacity（FVC）75%,FVC50%,and FVC25% in the observation group were not with statistically significant difference．The measured/predicted values of FVC and FEV₁ in the observation group A were lower than those in the observation group B,and the difference was statistically significant（P<0.05）．There was no statistically significant difference in pulmonary function between the two groups of pediatric patients with pulse oscillation（P>0.05）．Among the 90 patients,12 had abnormal conventional ventilation．The measured/predicted values of VCMAX,FVC75%,and FVC50% before and after treatment were not significantly different．The measured/predicted values of FVC,FEV₁,PEF,and FVC25% before treatment were lower than those after treatment,and the difference was statistically significant（P<0.05）．Conclusions There is good correlation between conventional ventilation and pulse oscillation．Airway resistance has a reverse effect on VCMAX and FVC．MP infected lobar pneumonia is mainly characterized by impaired small airway ventilation function and increased airway resistance．
