OBJECTIVE To investigate the application status of prescription pre-review systems in healthcare institutions of Yunnan province， evaluate their system functions and management capabilities， and provide a practical basis for promoting rational drug use. METHODS A questionnaire survey was conducted among public healthcare institutions at or above the secondary level in Yunnan province to investigate the deployment status of the systems. A capability maturity assessment framework was constructed， encompassing 6 dimensions and 39 indicators， including real-time prescription review， prescription correlation review， rule setting， evidence-based information support， prescription authority management， and system operation management. This framework was then used to evaluate the institutions that had implemented the pre-review systems. RESULTS A total of 100 valid questionnaires were collected， with 37 institutions having adopted prescription pre-review systems， mainly tertiary hospitals. The system predominantly adopted a modular architecture and was embedded into the hospital information system through application programming interfaces and middleware， providing certain capabilities for real-time prescription risk identification. Evaluation results indicated that basic functions such as reviewing indications， contraindications， and drug compatibility performed well， while deficiencies remained in functions related to parenteral nutrition prescription， review of drug dosage for specific diseases， individual patient characteristic recognition， and rule setting. Moreover， the construction of review centers and establishment of management systems were also not well-developed. CONCLUSIONS The overall application rate of prescription pre-review systems in Yunnan province remains low. System functions and management mechanisms require further improvement. It is recommended to enhance information infrastructure in lower-level institutions and explore regionally unified review models to promote standardized and intelligent development of prescription review practices.

Objective:To investigate the features of peripheral blood lymphocyte subsets in children with sepsis and evaluate the value of these cells in combination with multiple indicators in the diagnosis of pediatric sepsis.Methods:A retrospective study was conducted on 86 sepsis children and 83 children with local infection admitted to Hebei Children′s Hospital from October 2022 to October 2024. Baseline clinical data, peripheral blood lymphocyte subsets, and other laboratory indicators were compared between the two groups. The least absolute shrinkage and selection operator (LASSO) regression and multivariate logistic regression were used to evaluate the independent risk factors correlated with the initiation of sepsis. The receiver operating characteristic (ROC) curve was plotted to evaluate the value of each independent risk factor for diagnosing sepsis.Results:The thrombin time, the absolute counts of NK, CD3 + T, CD4 + T, and CD8 + T cells, the levels of IgG and IgM, and the counts of lymphocytes and platelets were lower in the sepsis children than in the children with local infection. However, the prothrombin time (PT), activated partial thromboplastin time, the levels of fibrinogen, direct bilirubin, and C-reactive protein (CRP) were higher in the sepsis group (all P<0.05). The variables screened by LASSO regression were analyzed by the multivariate logistic regression, and the results showed that PT, absolute CD4 + T cell count, and the levels of IgM and CRP were independent risk factors for sepsis. The ROC analysis indicated that the area under the ROC curve (AUC) for PT, absolute CD4 + T cell count, and IgM and CRP levels when used individually in diagnosing sepsis was 0.729, 0.593, 0.605, and 0.795, respectively. The AUC for the four indexes when used in combination for diagnosing sepsis reached 0.822, showing greater superiority over that of the single index. Conclusions:The combined measurement of PT, absolute CD4 + T cell count, and the levels of IgM and CRP can improve the diagnostic efficacy for sepsis in children. Early monitoring of these indexes facilitates the assessment of the condition in children suffering from sepsis.

Objective:To investigate the risk factors for death in children with acute necrotizing encephalopathy (ANE) in pediatric intensive care unit (PICU).Methods:This was a multicenter retrospective study. Thirty-nine children with ANE were from PICUs in 4 centers from December 1, 2014 to December 1, 2020. The 4 participating centers were Beijing Children′s Hospital, Shengjing Hospital of China Medical University, Hebei Children′s Hospital, and Bao′an Maternity & Child Health Hospital. Patients were divided into survival and non-survival groups by the outcome at discharge, and the differences in clinical data between the two groups were compared. Risk factors for death in children with ANE and the odds ratios ( OR) were analyzed by univariable Logistic regression. Results:Thirty-nine children with ANE were included. There were 18 males and 21 females. The median onset age was 30 months. The mortality at discharge was 41% (16/39). The onset age of most patients (74%, 29/39) was younger than 4 years old. Influenza virus was the most common precursor infection (80%, 20/25). Patients with shock at PICU admission were more common in the non-survival group (12/16 vs. 17% (4/23), P=0.001). Glasgow coma score (GCS) at PICU admission was significantly lower in the non-survival group than survival group (3 (3, 6) vs. 6 (5, 7), Z=-2.598, P=0.009). The optimal cut-off value was 4. The proportion of patients with GCS ≤ 4 at PICU admission was higher in the non-survival group (10/16 vs. 22% (5/23), P=0.018). ANE severity score (ANE-SS) at PICU admission was significantly higher in the non-survival group (5 (2, 6) vs. 2 (1, 4), Z=-2.436, P=0.015). The proportion of patients with high risk ANE-SS was higher in non-survival group than the survival group (9/16 vs. 22% (5/23), P=0.043). The proportion of application of high-dose methylprednisolone (20 mg/(kg·d)) was significantly higher in survival group than non-survival group (43% (10/23) vs. 1/13, P=0.031). Univariable Logistic regression indicated that risk factors for death in children with ANE were shock ( OR=14.250, 95% CI 2.985-68.018, P=0.001), GCS≤4 ( OR=6.000, 95% CI 1.456-24.733, P=0.013) and high risk ANE-SS ( OR=4.629, 95% CI 1.142-18.752, P=0.032) at PICU admission. Conclusions:ANE usually occurs in children under 4 years old after influenza infection. Shock, GCS≤4 and high risk ANE-SS at PICU admission were risk factors for death in children with ANE. High-dose methylprednisolone may improve the prognosis of children with ANE.

ABSTRACT OBJECTIVE：To compare the effectiveness and economics of peramivir and oseltamivir in the treatment of influenza complicated with febrile seizures in children. METHODS：In retrospective study，152 children with influenza complicated with febrile seizures were collected from our hospital during Dec. 2018 to Mar. 2019.They were divided into peramivir group（81 cases） and oseltamivir group （71 cases）. Fever remission time， medication duration， hospital duration， clinical efficacy （determined by convulsion，cough，nasal obstruction，runny nose，sore throat，etc.），the incidence of rash，the number of children with combined antibiotic and TCM were compared between 2 groups. Cost-effectiveness analysis was used to evaluate cost-effectiveness ratio（CER）and incremental cost-effectiveness ratio（ICER）of medication regimen in 2 groups. The sensitivity analysis of the effect and total cost were carried out with Logistic regression and multiple linear regression respectively through CER and ICER calculated by reducing 15％ drug price. RESULTS：There was no statistical significance in fever remission time， medication duration，hospitalization duration，the incidence of rash and proportion of children with combined antibiotics between 2 groups（P＞0.05）. There was statistical significance in proportion of children with combined TCM and clinical effect，and the proportion of children with combined TCM in peramivir group was significantly lower than oseltamivir group（P＜0.001）. Clinical effect of peramivir group was significantly better than that of oseltamivir group（P＝0.021）. Total cost of peramivir group and oseltamivir group were 5 442.84 yuan/person and 5 571.71 yuan/person（P＝0.795）；CER of them were 54.47 and 56.51；ICER of peramivir group was － 89.38. The results of sensitivity analysis were consistent with those of basic analysis.CONCLUSIONS： Compared with oseltamivir，peramivir is more effective and less costly for children with influenza and febrile seizures.

Objective To provide useful information for the diagnosis and differentiation through exploring the tumor with polyserositis as the initial symptom.Methods There was a case present with fever,poor spirit,abdominal distention and edema in Children's Hospital of Hebei Province.The characteristics and results of physical examination were summarized and discussed according to the condition evolution phases.The possible etiological factors were analyzed.The treatment was adjusted.Further physical examination was improved.The final diagnosis was tracked.Results After getting admitted to hospital,the patient received CT scan and ultrasound examination for many times.The results suggested the pericardial effusion,pleural effusion,peritoneal effusion and cardiac insufficiency.The child had made a slight improvement through treatment.However,he had hemiparesis.Cerebral infarction was demonstrated through magnetic resonance imaging(MRI),magnetic resonance angiography (MRA),magnetic resonance venography (MRV).Ultrasound showed that there was more pericardial effusion,aortic root solid low echo mass,pulmonary arterial wall stiffness,left and right pulmonary artery blood flow speed increased.Neck and chest enhanced CT showed mediastinal lesions.Pathology examination results suggested myeloid sarcoma after referral to superior hospital.Conclusions When children had an unexplained polyserositis,more comprehensive analysis were needed.The illness condition should be explained with Monism as far as possible.Repeated inspections would be necessary when the pathogenesis was not clear.Careful watch for the tumor should be kept.

Purpose Median arcuate ligament (MAL) compression is the most common reason for celiac artery stenosis or occlusion, celiac artery compression of asymptomatic MAL is often misdiagnosed. This study aims to evaluate the multi-slice spiral CT manifestations of the celiac artery compression of median arcuate ligament. Materials and Methods CT features of 26 patients with celiac artery compression of median arcuate ligament were retrospectively studied. Eleven cases were symptomatic and fifteen cases were asymptomatic. Results In 14 cases (53.8%), the location of compression was at the level of superior 1/3 of the L1 vertebral body. There was statistic difference in location of the origin of compression between the celiac artery narrowing group and the non-narrowing group (P<0.05). CT manifestations included: narrowing of the celiac artery were observed in 26 patients on sagittal reformatted images with hollow on the anterior wall; a characteristic hooked appearance was observed. Narrowed celiac artery on the transverse images was seen in 21 patients, and a soft-tissue band extending across the anterior aspect of artery in 12 of them. Poststenotic dilatation was revealed in 20 patients. Collateral circulation was seen in 8 patients. Conclusion Multi-slice spiral CT can be helpful in demonstrating the location of celiac artery compression of median arcuate ligament and tell the characteristic imaging features.
