Objective:To evaluate the clinical efficacy of Huzhang Polou Decoction combined with acupoint application in the treatment of children with mycoplasma pneumoniae pneumonia (MPP) complicated with atelectasis.Methods:A total of 105 MPP children with atelectasis and phlegm-heat obstructing lung syndrome in our hospital from August 2019 to March 2022, who met the inclusion criteria, were divided into control group (53 cases) and observation group (52 cases), by random number table method. The control group was given azithromycin sequential therapy on the basis of conventional western medicine treatment, and the observation group was given Huzhang Polou Decoction and acupoint application on the basis of the control group. Both groups were treated for 19 days. TCM syndromes were scored before and after treatment. The FEV1 and peak expiratory flow rate (PEF) were measured by pulmonary function measurement instrument. The CRP was measured by immunoturbidimetry and procalcitonin (PCT) was measured by ELISA. The recovery time of fever, disappearance time of cough and sputum, disappearance time of lung rales, lung recruitment time, and adverse reactions during treatment were recorded, and the clinical efficacy was evaluated.Results:The total effective rate was 96.15% (50/52) in the observation group and 84.91% (45/53) in the control group, and the difference between the two groups was statistically significant ( χ2=3.85, P=0.050). After treatment, the TCM syndrome score of the observation group was significantly lower than that of the control group ( t=22.78, P<0.01). FEV1 [(1.87±0.29) L vs. (1.54±0.28) L, t=5.93] and PEF [(79.82±6.29) L/min vs. (74.32±6.30) L/min, t=4.48] were significantly higher than those in the control group ( P<0.01). The levels of serum CRP [(9.18±2.98) mg/L vs. (12.34±3.00) mg/L, t=5.42] and PCT [(0.60±0.15) ng/L vs. (0.96±0.21) ng/L, t=9.93] were significantly lower than those in the control group ( P<0.01). The recovery time of fever, disappearance time of cough and sputum, disappearance time of lung rale and lung recruitment time in the observation group were significantly earlier than those in the control group ( t=7.27, 6.84, 3.76, 5.87, all Ps<0.01). During treatment, the incidence of adverse reactions was 3.77% (2/53) in the control group and 1.92% (1/52) in the observation group, and there was no significant difference between the two groups ( χ2=0.32, P=0.569). Conclusion:The Huzhang Polou Decoction combined with acupoint application can improve the pulmonary function of children with MPP complicated with atelectasis, reduce the level of serum inflammatory cytokines, improve the clinical efficacy safely.

Objective To verify and monitor the performance of accuracy, precision and comparability of 26 clinical biochemical analytes (29 methods) in the six centers involved in multi-centers reference intervals research, and to ensure the reliability of theirmeasurement results.Methods During the period of the systems evaluating, two levels of commercial quality control materials and fresh frozen human serum reference materials were applied to verify the performance of inter-laboratory precision and accuracy of analysis systems.
