Objective:To retrospectively analyze the anesthetic management characteristics of children undergoing resection of pheochromocytoma and paraganglioma (PPGL).Methods:The clinical data from patients undergoing resection of PPGL and confirmed histologically from January 1, 2010 to June 30, 2023 were retrospectively collected. The baseline characteristics, intraoperative conditions and postoperative complications were recorded.Results:The clinical data from 47 pediatric patients were analyzed. The overall incidence of hemodynamic instability events was 68% (32 cases). Lowering preoperative blood pressure to normal levels and the maximum diameter of tumor≥6 cm was helpful in reducing the incidence of the intraoperative hemodynamic instability events ( P<0.05). Postoperative hypotension developed in 7 cases, acute left heart failure in 1 case, arrhythmia in 1 case, adrenocortical insufficiency in 4 cases, and pulmonary infection in 13 cases. Conclusions:Thorough preoperative preparation, evidence-based anesthetic management, and meticulous postoperative vital sign monitoring can increase the perioperative safety for children undergoing resection of PPGL, thereby reducing the incidence of complications.

Objective:To assess the feasibility of wavelet index (WLI) in monitoring the depth of sedation with propofol in pediatric patients.Methods:This was a prospective observational trial. One hundred and sixty-five pediatric patients, aged >1-12 yr, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, undergoing elective surgery requiring general anesthesia with endotracheal intubation or laryngeal mask airway from July to December 2016 in our hospital, were divided into 11 age groups ( n=15 each): >1-2 yr group, >2-3 yr group, >3-4 yr group, >4-5 yr group, >5-6 yr group, >6-7 yr group, >7-8 yr group, >8-9 yr group, >9-10 yr group, >10-11 yr group, and >11-12 yr group. General anesthesia was induced by injection of propofol 3 mg/kg for more than 30 s. WLI and BIS values were recorded immediately before administration and at 30, 40, 50, 60, 90, 120, 180 and 240 s after the end of administration. If there were differences among age groups, age groups with no statistically significant differences were combined and re-grouped. Pearson linear correlation analysis and Bland-Altman consistency analysis were performed. Results:A total of 149 pediatric patients were actually included. There were no significant differences in BIS values between 4 groups aged > 1-5 yr and between 7 groups aged > 5-12 yr ( P>0.05). Regrouping was performed based on the aforementioned results, 4 groups of children aged > 1-5 yr were divided into > 1-5 yr group ( n=60), and 7 groups of children aged > 5-12 yr were divided into > 5-12 yr group ( n=89). WLI values and BIS values were significantly decreased at each time point after administration compared with immediately before administration in group aged > 1-5 yr and in group aged >5-12 yr ( P<0.05). The BIS values were the lowest at 60 s after the end of the administration, and the WLI values were the lowest at 120 and 180 s after the end of the administration in two groups ( P<0.05). There were no statistically significant differences between WLI values and BIS values at 90 s and 240 s after the end of the administration ( P>0.05), and there was statistically significant difference at the other time points in group aged > 1-5 yr ( P<0.05). There was no significant difference between WLI values and BIS values at 180 s and 240 s after the end of the administration ( P>0.05), but there were significant differences at the other time points in group aged > 5-12 yr ( P<0.05). The Pearson correlation coefficients between WLI values and BIS values were 0.61 and 0.56 in group aged > 1-5 yr and group aged > 5-12 yr, respectively ( P<0.001). Bland-Altman agreement analysis: In group aged > 1-5 yr and group aged > 5-12 yr, the 95% agreement limits were -0.484-0.621 and -0.551-1.015, respectively, and there were 4.6% (23/504) and 5.1% (40/777) of the points outside the 95% agreement limits, respectively, and both limits exceeded the clinically acceptable range. Conclusions:WLI is feasible for monitoring the depth of sedation with propofol in pediatric patients aged > 1-12 yr, but the accuracy is lower than BIS.

Objective To investigate the knowledge,attitude and practice(KAP)of medical staff and parents of children on the risk of using traditional Chinese patent medicine,analyze the similarities and differences between the two groups of people in their knowledge of traditional Chinese patent medicine,medication attitudes and medication behaviors,and analyze the influencing factors of traditional Chinese patent medicine medication risk from the perspective of"doctor-patient",so as to better guide clinical work.Methods From July to November 2023,the medical staff of Children's Hospital Affiliated to the Capital Institute of Pediatrics(hereinafter referred to as"our hospital")and other hospitals,as well as the parents of children who had visited our hospital and taken traditional Chinese patent medicine were taken as the subjects of the survey.The questionnaires were distributed and collected by Questionnarie Stars to analyze the KAP scores of medical staff and parents of children on the risk of children using traditional Chinese patent medicine,and the factors influencing the scores of KAP of taking traditional Chinese patent medicine were analyzed using Logistic regression analysis.And Spearman correlation analysis was used to explore the correlation among knowledge,attitude and practice.Results A total of 339 valid questionnaires(the effective recovery rate of 98.83%)were collected from the medical staff version of the questionnaire.The medical staff with excellent knowledge,attitude and practice scores accounted for 16.22%,7.08%and 83.19%,respectively.A total of 336 valid questionnaires(the effective recovery rate of 98.82%)were collected from the parents'version.The parents of the children with excellent knowledge,attitude and practice scores accounted for 25.87%,3.57%and 30.65%,respectively.Logistic regression analysis showed that different hospital locations and educational levels were important influencing factors for the KAP of medical personnel,while the age,education level,work status,occupation,and monthly income of parents were important influencing factors for their KAP(P<0.05).The Spearman correlation analysis results showed a significant positive correlation among medication knowledge,attitude,and behavior(P<0.01).Conclusion Medical staff and parents of children need to further improve their knowledge and attitude towards the use of traditional Chinese patent medicine.Parents need to pay special attention to standardizing drug use practice,so as to reduce the risk of children using traditional Chinese patent medicine.Physicians and pharmacists can carry out appropriate traditional Chinese patent medicine knowledge popularization and science popularization for parents of children combined with the results of this study.

Anti-seizure medications (ASMs) are the main therapy for epilepsy.There are many kinds of ASMs with complex mechanism of action, so it is difficult for pharmacists to examine prescriptions.This paper put forward some suggestions on the indications, dosage forms/routes of administration, appropriateness of usage and dosage, combined medication and drug interaction, long-term prescription review, individual differences in pathophysiology of children, and drug selection when complicated with common epilepsy, for the reference of doctors and pharmacists.

The role of glial scar after intracerebral hemorrhage(ICH)remains unclear.This study aimed to inves-tigate whether microglia-astrocyte interaction affects glial scar formation and explore the specific function of glial scar.We used a pharmacologic approach to induce microglial depletion during different ICH stages and examine how ablating microglia affects astrocytic scar formation.Spatial transcriptomics(ST)analysis was performed to explore the potential ligand-receptor pair in the modulation of microglia-astrocyte interaction and to verify the functional changes of astrocytic scars at different periods.During the early stage,sustained microglial depletion induced disorganized astrocytic scar,enhanced neutrophil infiltration,and impaired tissue repair.ST analysis indicated that microglia-derived insulin like growth factor 1(IGF1)modulated astrocytic scar formation via mechanistic target of rapamycin(mTOR)signaling activation.Moreover,repopulating microglia(RM)more strongly activated mTOR signaling,facilitating a more protective scar formation.The combination of IGF1 and osteopontin(OPN)was necessary and sufficient for RM function,rather than IGF1 or OPN alone.At the chronic stage of ICH,the overall net effect of astrocytic scar changed from protective to destructive and delayed microglial depletion could partly reverse this.The vital insight gleaned from our data is that sustained microglial depletion may not be a reasonable treatment strategy for early-stage ICH.Inversely,early-stage IGF1/OPN treatment combined with late-stage PLX3397 treatment is a promising therapeutic strategy.This prompts us to consider the complex temporal dynamics and overall net effect of microglia and astrocytes,and develop elaborate treatment strategies at precise time points after ICH.

Objective:To evaluate the accuracy of bedside lung ultrasound in predicting postoperative pulmonary complications (PPCs) in the patients undergoing radical resection of gastrointestinal cancer.Methods:One hundred and eight patients of both sexes, aged >18 yr, undergoing elective radical resection of gastrointestinal cancer with general anesthesia, were enrolled in the study. Lung ultrasound was performed before surgery (T 1) and at 2, 4 and 7 days after surgery (T 2-4). Lung ultrasound score (LUS) and B-line score were recorded. Serum procalcitonin (PCT) concentrations and blood routine were recorded, and systemic immune-inflammatory index (SII) was calculated. All the patients underwent chest CT examination before surgery and 7 days after surgery. The results of chest CT and clinical diagnosis were used as the gold standard for PPCs. The occurrence of PPCs within 7 days after surgery was recorded. The patients were divided into PPCs group and non-PPCs group according to the development of PPCs. Spearman′s correlation analysis was used to analyze the correlation of B-line score and LUS with PPCs, PCT and SII. The receiver operating curve was used to evaluate the accuracy of B-line score and LUB in predicting PPCs. Results:One hundred and three patients were finally enrolled in the study, including 45 patients in PPCs group and 58 patients in non-PPCs group, and the incidence of PPCs was 43.7%. Both B-line score and LUS were positively correlated with PPCs at T 1 ( P<0.001), and B-line score and LUS were positively correlated with PCT and SII at T 2-4 ( P<0.001). The AUC (95% confidence interval) of B-line score and LUB in predicting PPCs were 0.926 (0.879-0.972) and 0.909 (0.852-0.965), respectively ( P<0.001), the best cut-off values of B-line score and LUB in predicting PPCs were set at 25.5 and 11.5 respectively, and the sensitivity and specificity of B-line score were 0.80 and 0.88 respectively, and the sensitivity and specificity of LUB were 0.78 and 0.93 respectively. Conclusions:Bedside pulmonary ultrasonography (B-line score and LUS) can accurately predict the occurrence of PPCs in the patients undergoing radical resection of gastrointestinal cancer and dynamically evaluate the condition of PPCs, and B-line score >25.5 and LUS score >11.5 indicate a high risk of PPCs.

Bioinformatics is an interdisciplinary science that combines the tools of mathematics, computer science, and biology to clarify and explore the biological implications of large amounts of biological data. With the continuous development of genome sequencing technology, a large number of biological data has been generated, and mining of the biological significance contained in big data has become one of the main tasks that need to be solved urgently. This article summarizes the risk prediction models for hepatocellular carcinoma (HCC) based on feature genes, so as to provide new perspectives for early identification, prognosis, and treatment optimization of HCC.

Hepatocellular carcinoma (HCC) is a malignant tumor with high incidence in China and the whole world, and early diagnosis and treatment are the key to improving the prognosis of patients. To facilitate the communication and cooperation between doctors of different centers and specialties, American College of Radiology issued the first edition of contrast-enhanced ultrasound (CEUS) Liver Imaging Reporting and Data System (LI-RADS) in 2016 to standardize the technical terms, techniques, interpretation, reporting, and data collection for liver imaging and perform HCC risk stratification for different focal liver lesions. This article reviews the development and clinical application of CEUS LI-RADS and believes that the application of CEUS LI-RADS has a great potential value in the clinical management of focal liver lesions in the population at a high risk of HCC, and the applicable population and indications for CEUS LI-RADS will continue to expand in the near future, so as to provide better service to clinical practice.

Objective:To explore the current status and influencing factors of breathlessness beliefs in patients with chronic obstructive pulmonary disease (COPD) .Methods:Using the convenient sampling method, a total of 167 COPD patients who were admitted to Henan Provincial People's Hospital from April to September 2021 were selected as the research objects. The general information questionnaire, The Breathlessness Beliefs Questionnaire (BBQ) , Social Support Revalued Scale (SSRS) and Multidimensional Fatigue Inventory-Short Form (MFI-SF) were used for questionnaire survey.Results:The BBQ score of 167 COPD patients was (40.92±8.77) , the MFI-SF score was (54.83±14.21) and the SSRS score was (41.23±8.19) . The results of multiple linear regression analysis showed that disease grouping, general fatigue, physical fatigue and MFI-SF were the influencing factors of breathlessness beliefs in COPD patients ( P<0.05) . Conclusions:The breathlessness belief in COPD patients is related to disease grouping and fatigue degree, suggesting that relevant measures should be taken to reduce the cognitive level of fear of dyspnea and activity, so as to improve the exercise level and quality of life of patients.

Model informed precision dosing (MIPD) is a new concept to guide precision dosing for individual patient by modeling and simulation based on the available information about the individual patient, medications and the disease. Compared to the empirical dosing, MIPD could improve the efficacy, safety, economics and adherence of the pharmacotherapy according to the individual's pathophysiology, genotyping and disease progression. This consensus report provides a brief account of the concept, methodology and implementation of MIPD as well as clinical decision supporting systems for MIPD. The status and future advancing of MIPD was also discussed to facilitate the appropriate application and development of MIPD in China.
