OBJECTIVE To analyze adverse drug reactions （ADRs） in pediatric patients with Mycoplasma pneumoniae pneumonia （MPP）， and investigate the influential factors associated with the occurrence of ADRs. METHODS Clinical records of pediatric patients with MPP in Xinxiang Central Hospital （hereinafter referred to as “our hospital”） from Oct. 1st， 2023 to Sept. 30th， 2024 collected from the Hospital Information System were retrospectively reviewed using the global trigger tool （GTT）. The positive triggers were further reviewed to confirm the occurrence of ADRs， and the characteristics of those ADRs were analyzed. The children were divided into the ADR group and the non-ADR group. Univariate analysis and multivariate Logistic regression analysis were performed to investigate the potential influential factors for ADRs in MPP children. RESULTS A total of 1 325 MPP children were included. Out of 24 designed triggers， 14 were positive， with a positive trigger rate of 58.3%. There were 1 301 positive trigger cases， involving 846 pediatric patients. After assessment， 399 cases of ADRs were identified in 372 pediatric patients， yielding a positive predictive value of triggers at 30.7%. The main types of ADRs were abnormal blood cells （230 cases， 57.6%）， skin and its appendages damage （78 cases， 19.5%）， and gastrointestinal system damage （42 cases， 10.5%）， which predominantly occurred 4 days or more， within 2-3 days and within 2-3 days after medication， respectively. They were more prevalent in pediatric patients aged＞3-10 years （295 cases， 79.3%）. The major categories of drugs associated with ADRs included intravenous corticosteroids （209 cases）， cephalosporins （180 cases）， macrolides （38 cases）， tetracyclines （28 cases） and traditional Chinese medicine （TCM） injections （28 cases）. These ADR reports were classified into 3 types： 1 serious case， 394 general cases and 4 new cases. In terms of causality assessment， 1 case was assessed as certain， 19 cases as probable， and 379 cases as possible. In terms of ADR outcomes， 151 cases fully recovered， while the outcomes for 248 cases remained unknown. Univariate analysis and multivariate Logistic regression analysis revealed that a history of allergies [OR＝5.231， 95%CI （2.004， 13.656）， P＜0.05]， the number of medications used [OR＝1.064， 95%CI （1.027， 1.103）， P＜0.05]， and intravenous corticosteroid administration [OR＝3.223， 95%CI （2.341， 4.437）， P＜0.05] were independent risk factors of ADRs in pediatric patients with MPP. The use of azithromycin [OR＝0.544， 95%CI （0.376， 0.786）， P＜0.05] was identified as an independent protective factor against the occurrence of ADRs in pediatric patients with MPP. CONCLUSIONS Children with MPP in our hospital exhibit a higher incidence of ADRs， primarily involving abnormal blood cells， skin and its appendages damage， and gastrointestinal system damage. A history of allergies， the number of medications used， intravenous corticosteroid administration， and the use of azithromycin are associated with the occurrence of ADR in MPP pediatric patients.

OBJECTIVE: To explore the clinical effect of personalized puncture planning before surgery using Picture Archiving and Communication System (PACS) in the treatment of osteoporotic vertebral compression fractures in the elderly. METHODS: A total of 69 elderly patients with osteoporotic vertebral compression fractures treated by percutaneous vertebroplasty from January 2020 20 to December 2021 with more than 1 year of follow-up were analyzed retrospectively. Thirty-four patients were individualized for preoperative planning with PACS software (observation group), including 8 males and 26 females, with a mean age of (73.30±7.96) years old;and 35 patients were treated with conventional treatment (control group), including 7 males and 28 females, with a mean age of (77.30±7.84) years old. The operation time, the amount of cement injection, cement leakage rate, bone watertight diffusion and refracture within 1 year between two groups were observed and compared. The Cobb's angle, low back pain visual analogue scale(VAS) and the modified Oswsetry disability indexes(ODI) before surgery and 1 day, 1 year after surgery were compared between two groups. RESULTS: Both groups successfully completed the operation without serious surgical complications, 2 refractures occurred in the control group. The operation time in the observation group was(41.9±11.9) min, which was less than that in the control group (52.7±13.6) min (P<0.05). There was no significant difference in the cement injection volume between two groups (P>0.05). Two cases of cement leakage in the observation group was less than 8 in the control group (P<0.05). The bone cement distribution index of two groups had significant difference(P<0.05). There were no significant differences between two groups in Cobb's angle of the injured vertebras and ODI before and 1 day after surgery(P>0.05), however, the comparative differences were statistically significant at 1 year after surgery(P<0.05). There was no significant difference in the VAS between two groups at each time period(P>0.05). CONCLUSION Using the PACS software to plan personalized puncture scheme can reduce the operation time, reduce the cement leakage rate, improve the diffusion of bone cement and longer maintain the postoperative form of vertebral body and the functional state of patients' lumbar back.

Schizophrenia (SZ) stands as a severe psychiatric disorder. This study applied diffusion tensor imaging (DTI) data in conjunction with graph neural networks to distinguish SZ patients from normal controls (NCs) and showcases the superior performance of a graph neural network integrating combined fractional anisotropy and fiber number brain network features, achieving an accuracy of 73.79% in distinguishing SZ patients from NCs. Beyond mere discrimination, our study delved deeper into the advantages of utilizing white matter brain network features for identifying SZ patients through interpretable model analysis and gene expression analysis. These analyses uncovered intricate interrelationships between brain imaging markers and genetic biomarkers, providing novel insights into the neuropathological basis of SZ. In summary, our findings underscore the potential of graph neural networks applied to multimodal DTI data for enhancing SZ detection through an integrated analysis of neuroimaging and genetic features.
