Objective To evaluate the diagnostic value of positive serum specific antibodies to Mycoplasma pneumoniae(MP)in children with Mycoplasma pneumoniae pneumonia(MPP).Methods PubMed,Cochrane Library,Embase,Sinomed,CNKI,Wanfang and VIP databases were searched for studies on the detection of MPP based on antibodies from the establishment of the database to March 31,2023.After literature screening and data extraction,STATA 16.0 software was used for Meta-analysis.Results A total of 9 literatures and 2 148 clinical samples were included.The combined sensitivities[M(95%CI)]of particle agglutination assay(PA)and enzyme-linked immunosorbent assay(ELISA)were 50%(31～69)and 88%(85～90),and the combined specificities[M(95%CI)]were 88%(76～95)and 88%(62～97).The combined diagnostic odds ratio(DOR)[M(95%CI)]were 5.61(3.30～9.53)and 43.82(12.78～150.19),and the summary receiver operating characteristic curve(SROC)area under the curve(AUC)were 0.80 and 0.88,respectively.Conclusion Serum MP specific antibody detection can be used for diagnosis and screening of children MPP,but needs to be combined with clinical symptoms improve the accuracy of the diagnosis.

Objective To explore the regulatory effect and mechanism of Zhongfeng Xinglou Tongfu Capsule on the brain inflammatory response of mice with cerebral hemorrhage through cholecystokinin octapeptide(CCK-8)mediated the interleukin 10(IL-10)/signal transduction and transcriptional activator 3(STAT3)signaling pathway.Methods A total of 110 C57BL/6 mice were divided into sham operation group,cerebral hemorrhage group,Zhongfeng Xinglou Tongfu Capsule low-,medium-,and high-dose groups according to the random number table method,with 22 mice in each group.The intracerebral hemorrhage model was established by collagenase method.At 2 hours after the establishment of the model,Zhongfeng Xinglou Tongfu Capsule suspension was intragastrically administered at a dose of 10 mL·kg-1.The sham operation group and the cerebral hemorrhage group were intragastrically administered with the same dose of normal saline.The neurofunctional score and left-turn rate of the mice were recorded.The dry and wet weight method was used to detect brain water content on the 72 h after surgery,and the Western Blot method was used to detect tumor necrosis factor-α(TNF-α),interleukin 1β(IL-1β),interleukin 6(IL-6),interleukin 10(IL-10),and the relative expression levels of JAK-1,STAT3,and p-STAT3 pathway proteins around the hematoma of mice at 72 h after surgery.On the 3rd and 5th day after surgery,Elisa method was used to detect the relative expression level of CCK-8,qPCR method was used to detect the expression levels of IL-10 and STAT3 mRNA.Results Compared with the cerebral hemorrhage group,the NDS scores of mice in the low-,medium-,and high-dose groups of Zhongfeng Xinglou Tongfu Capsules were significantly reduced on the 3rd and 5th days after intervention treatment(P＜0.01).And the left-turn rate in the low-dose group on the 3rd and 5th days after intervention treatment was reduced(P＜0.05),the left-turn rate in the medium-dose group was reduced on the 3rd day(P＜0.05)and the 5th day(P＜0.01).Furthermore,the left-turn rate was obviously reduced on the 3rd and 5th day in the high-dose group(P＜0.01).The brain water content of mice in the low-dose group was reduced(P＜0.05),and the brain water content of mice in the medium-and high-dose groups was significantly reduced(P＜0.01).In the low-dose group,the expressions of pro-inflammatory factors TNF-α,IL-6 and JAK-1,STAT3,and p-STAT3 pathway proteins were significantly reduced(P＜0.01),while the expression of IL-1β was reduced(P＜0.05),the expression of IL-10 increased significantly(P＜0.01).The expression of pro-inflammatory factors TNF-α,IL-1β,IL-6,as well as JAK-1,STAT3,and p-STAT3 pathway proteins in the medium-and high-dose groups was significantly reduced(P＜0.01),the expression of anti-inflammatory factor IL-10 increased significantly(P＜0.01).The content of CCK-8 in the low-dose group was increased on the 3rd day after treatment(P＜0.05),and the content increased significantly on the 5th day(P＜0.01).The content of CCK-8 in the medium-and high-dose groups obviously increased on the 3rd and the 5th day after treatment(P＜0.01).The relative expression level of IL-10 mRNA was significantly increased after treatment(P＜0.01),but the relative expression level of STAT3 mRNA was significantly decreased after treatment(P＜0.01).Conclusion Zhongfeng Xinglou Tongfu Capsule can target the content of brain-gut peptide CCK-8 and regulate the IL-10/STAT3 signaling pathway to reduce the secondary inflammatory reaction and cytotoxic brain edema after cerebral hemorrhage.
