ObjectiveTo investigate the effect of different visual inputs and task conditions on balance function and lower limb biomechanical characteristics in children with spastic hemiplegia. MethodsFrom March to July, 2025, 30 children aged six to nine years old with spastic hemiplegia (hemiplegia group) and 30 healthy children (control group) were selected. A 2×2×2 mixed experimental design was employed, involving groups (hemiplegia vs. healthy), tasks (single-task vs. dual-task), and vision (eyes open vs. eyes closed). One week before test, they were evaluated with Fugl-Meyer Assessment-Lower Extremities (FMA-LE), Wee Function Independent Measurement (WeeFIM) and Wechsler Intelligence Scale for Children, Fourth Edition (WISC-Ⅳ). A 3D gait analysis system and a plantar pressure testing system were used to collect spatio-temporal parameters of walking speed, stride length, cadence and step width, kinematic parameters of hip/knee/ankle joint angles, kinetic parameters of forefoot loading ratio, center of pressure (CoP) displacement, while dual-task cost (DTC) was caculated. ResultsSpatio-temporal parameters showed that under dual-task and eyes-closed conditions, walking speed and stride length decreased while step width increased in the hemiplegia group. Significant interaction effects among group, task, and vision were observed for speed, stride length, and step width (F > 4.886, P < 0.05). Kinematic parameters indicated that during dual-tasks, the hemiplegia group exhibited increased hip flexion and decreased ankle dorsiflexion; under eyes-closed conditions, knee flexion increased. The interaction of the three factors significantly affected all joint angles (F > 4.876, P < 0.05). Kinetic parameters showed that under dual-task and eyes-closed conditions, the forefoot loading ratio and anteroposterior CoP displacement decreased, while mediolateral CoP displacement increased. The interaction of the three factors significantly affected CoP displacement (F > 4.355, P < 0.05). All the DTC was significantly higher in the hemiplegia group than in the control group, except DTC of the cadence (|t| > 14.393, P < 0.001). Correlation analysis revealed that the score of FMA-LE was strongly negatively correlated with DTC (|r| > 0.731, P < 0.01). The Functional Independence Measure for Children and Working Memory Index showed moderate negative correlations with the DTC of walking speed and cadence (|r| > 0.462, P < 0.05). ConclusionThe gait and balance of children with spastic hemiplegia are concurrently influenced by dual-tasking and visual input. The superposition of visual deprivation and dual-tasks significantly exacerbates gait abnormalities. Furthermore, is strongly correlated with motor function and working memory.

OBJECTIVE To analyze the potential adverse drug interactions （pADIs） of clarithromycin， and establish refined prescription pre-review rules. METHODS Outpatient prescriptions of clarithromycin in combination with other drugs were collected from January 1， 2024 to June 30， 2024 through hospital information system of the Third People’s Hospital of Bengbu. pADIs were identified and their risk severities were graded according to Lexicomp and Micromedex databases. Then， refined prescription pre- review rules for clarithromycin pADIs-related drugs were established according to the identification and risk level results. RESULTS Among 3 046 clarithromycin combined drug prescriptions， 946 cases of pADIs occurred in 812 prescriptions. There were 6， 415 and 525 cases classified as “contraindicated”，“ major” and “moderate”， respectively. The combination drugs with “contraindicated” levels were tamsulosin， rupatadine， domperidone and ticagrelor， while those with “major” levels were mainly theophylline， dexamethasone and amlodipine. Accordingly， 26 refined rules were established， including 4 items of “warning information→prescription interception”， 11 items of “warning information→prescription double signature” and 11 items of “attention information→prescription approval”. CONCLUSIONS There are “contraindicated” and “major” risks associated with clarithromycin and its combination drugs in the hospital， and refined prescription pre-review rules for clarithromycin combined drug prescription have been established successfully.

OBJECTIVE To analyze the potential adverse drug interactions based on pharmacokinetics （PK-pADIs） of gefitinib， and establish its corresponding prescription review rules. METHODS Outpatient prescriptions of gefitinib combination therapy in our hospital from January 1， 2022 to November 30， 2024 were collected through rational drug software system. PK- pADIs present in the prescriptions were identified based on the Drugs.com® drug interactions database. The specific combination drugs and cases of PK-pADIs were statistically analyzed， and prescription review rules were established according to the severity classification of PK-pADIs. RESULTS & CONCLUSIONS A total of 217 prescriptions of gefitinib combination therapy were enrolled. Among them， 28 prescriptions （12.90%）， involving a total of 28 patients， had 29 cases of PK-pADIs， with respiratory medicine prescriptions （22 prescriptions） being the main type. The combination drugs included proton pump inhibitors （13 cases）， strong cytochrome P450 3A4 （CYP3A4） inhibitors （7 cases）， H2 receptor antagonists （4 cases）， CYP3A4 inducers （3 cases）， and CYP2D6 substrates （2 cases）. The severity classifications for these interactions were severe， moderate， severe， moderate and moderate， respectively. Based on the above severity classification of PK-pADIs， four prescription review rules had been established as follows： when gefitinib was combined with acid-suppressing drugs， it should be subject to “manual review”； when gefitinib was combined with dexamethasone， metoprolol， or strong CYP3A4 inhibitors， an “alert” should be triggered， and the physician should be informed via an alert box to strengthen the monitoring of relevant indicators. Clinical pharmacists need to conduct in-depth training on knowledge related to gefitinib drug interactions in key clinical departments such as respiratory medicine. They should strengthen the monitoring and guidance of rational drug use for patients who are on long-term gefitinib therapy， and promptly identify and intervene in PK-pADIs， thereby enhancing the rationality， safety， and effectiveness of clinical drug use.

PURPOSE: Early mortality in major trauma has decreased, but MODS remains a leading cause of poor outcomes, driven by trauma-induced cytokine storms that exacerbate injuries and organ damage. METHODS: This prospective cohort study included 79 major trauma patients (ISS >15) treated in the National Center for Trauma Medicine, Peking University People's Hospital, from September 1, 2021, to July 31, 2023. Patients (1) with ISS >15 (according to AIS 2015), (2) aged 15-80 years, (3) admitted within 6 h of injury, (4) having no prior treatment before admission, were included. Exclusion criteria were (1) GCS score <9 or AIS score ≥3 for TBI, (2) confirmed infection, infectious disease, or high infection risk, (3) pregnancy, (4) severe primary diseases affecting survival, (5) recent use of immunosuppressive or cytotoxic drugs within the past 6 months, (6) psychiatric patients, (7) participation in other clinical trials within the past 30 days, (8) patients with incomplete data or missing blood samples. Admission serum inflammatory cytokines and pathophysiological data were analyzed to develop machine learning models predicting MODS within 7 days. LR, DR, RF, SVM, NB, and XGBoost were evaluated based on the area under the AUROC. The SHAP method was used to interpret results. RESULTS: This study enrolled 79 patients with major trauma, and the median (Q₁, Q₃) age was 51 (35, 59) years (52 males, 65.8%). The inflammatory cytokine data were collected for all participants. Among these patients, 35 (44.3%) developed MODS, and 44 (55.7%) did not. Additionally, 2 patients (2.5%) from the MODS group succumbed. The logistic regression model showed strong performance in predicting MODS. Ten key cytokines, IL-18, Eotaxin, MCP-4, IP-10, CXCL12, MIP-3α, MCP-1, IL-1RA, Cystatin C, and MRP8/14 were identified as critical to the trauma-induced cytokine storm and MODS development. Early elevation of these cytokines achieved high predictive accuracy, with an AUROC of 0.887 (95% CI 0.813-0.976). CONCLUSION Trauma-induced cytokine storms are strongly associated with MODS. Early identification of inflammatory cytokine changes enables better prediction and timely interventions to improve outcomes.
