ObjectiveTaking Aurantii Fructus Immaturus juice（AFI）-processed Atractylodis Macrocephalae Rhizoma（AMR） as an example， this study aims to systematically compare the volatile and non-volatile components of AMR and its processed products， investigate the key differential components， evaluate their anti-inflammatory activities， and elucidate the synergistic mechanism of processing. MethodsThe chemical compositions of volatile and non-volatile components in AMR and AFI-processed AMR were systematically characterized using gas chromatography-mass spectrometry（GC-MS） and ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS）， with relative mass fractions and response values determined separately. Volatile components were identified through searches in the National Institute of Standards and Technology（NIST）17 database， comparison with retention index（RI） and fragmentation pattern matching. Non-volatile components were identified by searching Waters Traditional Chinese Medicine （TCM） spectral library， in conjunction with PubChem and MassBank， characteristic fragmentation patterns and response values were also used to support identification. Differential components were screened using principal component analysis（PCA）， orthogonal partial least squares-discriminant analysis（OPLS-DA）， with variable importance in the projection（VIP） value >1. Components with high log₂fold change（FC） among major differential groups were selected as those exhibiting significant changes before and after processing. The anti-inflammatory activity of the differential compounds was evaluated by assessing their effects on nitric oxide（NO） production in a lipopolysaccharide（LPS）-induced RAW264.7 macrophage model. Enzyme-linked immunosorbent assay（ELISA） was used to detect the effects of the differential components on tumor necrosis factor（TNF）-α， interleukin（IL）-1β， IL-6， and monocyte chemotactic protein（MCP）-1 levels， and immunofluorescence（IF） was employed to assess their effects on nuclear transcription factor（NF）-κB p65 translocation， thereby elucidating the underlying molecular mechanisms. ResultsA total of 36 compounds were identified in the volatile components of AMR and AFI-processed AMR， among which， sesquiterpenes and monoterpenes were significantly increased after processing. In the non-volatile components， 36 compounds were identified， and the main differential components were flavonoids， sesquiterpenoids， and triterpenoids. Flavonoids were the primary differential components distinguishing AMR from its processed products， representing compounds directly introduced during processing. Five compounds， including atractylenolide Ⅲ， tangeritin， nobiletin， hesperidin and narirutin， were selected as representatives of three classes based on their most prominent differential expression among different compound types for subsequent anti-inflammatory activity studies. The results showed that 100 μmol·L^-1 tangerine and narirutin could significantly inhibit LPS-induced NO production（P<0.01） in a concentration-dependent manner. Tangeritin was able to significantly inhibit the levels of TNF-α and MCP-1 secreted by RAW264.7（P<0.05）， while narirutin significantly inhibited the levels of TNF-α， IL-1β， MCP-1 and IL-6（P<0.01）. IF revealed that both tangeritin and narirutin significantly blocked the translocation of NF-κB p65 from the cytoplasm to the nucleus. ConclusionAFI-processed AMR significantly alters the chemical composition profile of AMR， and the newly introduced flavonoid components during processing may be key to its enhanced anti-inflammatory effects.

Neonatal diabetes mellitus （NDM） is a rare monogenic disorder primarily caused by insufficient insulin secretion resulting from mutations in the KCNJ11 and ABCC8 genes. Sulfonylureas， represented by glibenclamide， have become the standard therapy for this type of NDM by precisely closing the mutated ATP-sensitive potassium channels in pancreatic β cells， thereby restoring insulin secretion. Clinical studies confirm that sulfonylureas enable over 90% of patients to successfully transition from insulin to oral treatment， achieving long-term stable glycemic control and improving neurological outcomes to a certain extent. In terms of safety， severe hypoglycemia induced by sulfonylureas is relatively rare and gastrointestinal reactions are mild； moreover， sulfonylureas show good long-term tolerability， and have no adverse effects on child growth and development. In the future， by further refining the full-chain management pathway of “rapid genetic diagnosis-early intervention-specialized dosage forms-long-term follow-up”， the clinical application of sulfonylureas is expected to provide NDM patients with an optimized treatment regimen and maximize their health benefits.

Objective:To evaluate the efficacy and safety of nebulized inhalation of recombinant human interferon (IFN) α1b injection in the treatment of respiratory syncytial virus (RSV) associated lower respiratory tract infections (pneumonia and bronchiolitis) in children.Methods:A randomized, double-blind, parallel, placebo-controlled add-on design was used.Children with pneumonia or bronchiolitis aged 2 months to 5 years who tested positive for RSV antigen within 72 hours of onset from 30 clinical trial sites including Beijing Children′s Hospital, Capital Medical University between February 2021 and December 2022 were included in this study and randomly divided into 2 groups at a ratio of 1∶1 based on a stratified-block method.Both groups received basic treatments such as cough control, asthma relieving, expectorant treatment, fever reduction, oxygen therapy, etc.The experimental group received additional nebulized inhalation of IFN α1b injection at a dose of 2.0 μg/(kg·time), twice a day.The control group received nebulized inhalation of placebo twice a day.Clinical efficacy was evaluated based on indicators such as the duration of clinical symptoms and signs, and the Kaplan-Meier method was used to calculate the median and 95% CI of the duration of clinical symptoms and signs.The Log-rank test was used to compared data between groups.Safety was assessed through the incidence of adverse reactions and laboratory tests, and the Chi-square test was used to analyze the difference between groups. Results:There were 123 children in the experimental group and 122 children in the control group.The median durations of all the 5 clinical symptoms and signs [including shortness of breath, wheezing, dyspnea (visible retractions), decreased transcutaneous oxygen saturation, and abnormal mental state] in the experimental group after treatment were slightly shortened than those in the control group [2.7 d(95% CI: 1.9-3.0 d)] vs.[2.9 d(95% CI: 2.6-3.6 d), P=0.027].The improvement in dyspnea (retractions) was especially pronounced in the experimental group, with a relief rate of 50.0% (0, 100%) on the first day of administration[compared with 0 (0, 50.0%) in the control group ( Z=2.002, P=0.025)].The median duration of dyspnea in the experimental group was nearly 1 day shorter than that in the control group [1.0 d(95% CI: 0.7-1.7 d) vs.1.8 d(95% CI: 1.0-2.5 d), P=0.046].There were no significant difference in hospital stay [6.0(5.0, 8.0) d vs.6.5(5.0, 8.0) d, Z=0.675, P=0.500], oxygen therapy duration [32.0(14.0, 96.3) h vs.39.0 (24.0, 83.2) h, Z=0.094, P=0.925], the recovery rate from clinical symptoms during treatment [(105/106, 99.1%) vs.(96/101, 95.0%)], and recurrence rate [(0/106, 0) vs.(2/101, 2.0%)] between the 2 groups (all P>0.05).However, the above-mentioned four indicators in the experimental group showed a trend of clinical benefits.The quantitative virus detection results showed that the RSV viral load in both groups decreased after treatment compared to before treatment.After 2 days of treatment, the decline rate of RSV viral load from the baseline was 0.90 lg copies/(mL·d) in the experimental group and 0.25 lg copies/(mL·d)in the control group, with a statistically significant difference ( P<0.05).Furthermore, there was no statistically significant difference in the incidence of adverse reactions between the 2 groups ( P>0.05).Importantly, no drug-related serious adverse reactions occurred in both groups. Conclusions:The nebulized inhalation therapy of IFN α1b demonstrates efficacy and safety in treating pediatric RSV associated lower respiratory tract infections.It particularly offers outstanding clinical therapeutic value for severe children.

Objective:To develop an early exercise rehabilitation nursing for elderly patients undergoing total hip arthroplasty (THA) based on the best evidence, and explore its clinical effects.Methods:This study was a randomized controlled trial. From August to December 2022, convenience sampling was used to select 126 elderly THA patients admitted to the Department of Orthopedics of the First Affiliated Hospital of Naval Medical University as participants. Patients were divided into observation group and control group using a random number table method, with 63 cases in each group. Control group was treated with a usual exercise rehabilitation nursing, while observation group was treated with an early exercise rehabilitation nursing for elderly THA patients based on the best evidence. Changhai Pain Rating Scale, Harris Hip Score, and Barthel Index were used to evaluate pain, hip function, and activities of daily living in two groups of patients. The first time off the bed, hospital stay, and incidence of complications were recorded and compared between the two groups.Results:The Harris Hip scores of observation group patients three days after surgery and on the day of discharge were (61.13±4.82) and (77.84±4.43), respectively, which were higher than those of control group (50.75±6.19) and (70.25±7.47), and the differences were statistically significant ( t=10.502, 6.937; both P<0.01). Barthel Index scores of observation group patients were higher than those of control group on the day of surgery, three days after surgery, and the day of discharge, and the differences were statistically significant ( t=3.531, 4.609, 10.112; all P<0.01). The incidence of postoperative complications in observation group was 11.11% (7/63), while in control group it was 42.86% (27/63), with a statistically significant difference (χ 2=16.113, P<0.01). There were no statistically significant differences in the resting pain score and exercise pain score between the two groups of patients on the day after surgery ( t=-1.693, -1.354; both P>0.05). The resting pain score and exercise pain score of observation group were lower than those of control group three days after surgery and on the day of discharge, and the differences were statistically significant (all P<0.05). Observation group had a shorter first time off the bed and hospital stay (1.34±0.37) and (5.48±0.66) days compared to control group (2.13±0.48) and (6.29±0.83) days, with statistically significant differences ( t=-10.346, -6.063; both P<0.01) . Conclusions:An evidence-based early exercise rehabilitation nursing for elderly THA patients can reduce the degree of pain, minimize the occurrence of complications, shorten the first time off the bed and hospital stay, and promote recovery of elderly patient.

Gastric cancer is one of the most common malignant tumors worldwide and presents many treatment challenges,especially in relation to late-stage treatment and its high recurrence rate.Angiogenesis is a key process in the growth and metastasis of gastric cancer,and studies aimed at researching and developing anti-angiogenesis therapies are therefore important for the treatment of gastric cancer.Exosomes are nanoscale vesicles released by cells,which serve as important messengers for intercellular communication.They regulate local and distant cell communication by transporting specific exosomes components,and it can also promote or inhibit the development and progression of gastric cancer by regulating the growth,proliferation,and angiogenesis of tumor cells.Exosomes transport bioactive molecules from donor cells to recipient cells,leading to reprogramming of target cells and cascade molecular reactions.This review summarizes the relationship between exosomes and tumor angiogenesis in gastric cancer,and the current research status of exosomes in anti-angiogenic therapy.The importance of the physiological structure and function of exosomes in gastric cancer angiogenesis indicates the potential importance of combining exosomes with anti-angiogenic therapy for the treatment of gastric cancer.

Objective:To explore the trajectory of changes in electronic health literacy in young and middle-aged patients with coronary heart disease (CHD) combined with diabetes mellitus (DM) after percutaneous coronary intervention (PCI), and to analyze its relationship with unplanned readmission within 30 days.Methods:A convenience sample of 210 young and middle-aged CHD patients with DM who underwent PCI in the Department of Cardiology, Xinxiang Central Hospital, from February 2023 to June 2024 was selected. The e-Health Literacy Scale (eHEALS) was used to assess electronic health literacy at the 3rd day (T 1), 15th day (T 2), and 30th day (T 3) after PCI. Unplanned readmission within 30 days after discharge was recorded. Latent class growth model (LCGM) was used to identify categories and characteristics of electronic health literacy trajectories. Kaplan-Meier method was applied to plot the cumulative incidence of 30-day unplanned readmission, and the Log-Rank test was used to compare differences among different trajectory types. Results:A total of 207 patients completed the entire survey and follow-up, with a valid response rate of 98.57% (207/210). eHEALS scores gradually increased after PCI, with scores of (6.75±1.31), (11.55±3.31), and (15.56±5.75) at T 1, T 2, and T 3, respectively. Two potential categories were identified: persistent low-level type (85 cases, 41.06%) and gradually improving type (122 cases, 58.94%). Twenty-six patients experienced unplanned readmission within 30 days, with an incidence of 12.56%. The proportions of unplanned readmission within 30 days were 20.00% (17/85) in the persistent low-level group and 7.38% (9/122) in the gradually improving group, with a statistically significant difference (χ 2=7.268, P=0.007). Kaplan-Meier cumulative risk function analysis showed that the cumulative incidence of 30-day unplanned readmission in the gradually improving group was lower than that in the persistent low-level group, with a statistically significant difference (Log-Rank=7.683, P=0.006) . Conclusions:Young and middle-aged CHD patients with DM after PCI show trajectory characteristics in electronic health literacy. Although the electronic health literacy of some patients gradually improved after PCI, persistent low-level literacy was still common, and patients in the persistent low-level group had a higher risk of 30-day unplanned readmission, which deserves clinical attention.

Objective:To assess the preliminary efficacy and safety of modified Société Internationale d′Oncologie Pédiatrique Epithelial Liver Tumor Study Group (SIOPEL)-4 protocol for pediatric hepatoblastoma (HB) with lung metastases.Methods:This prospective cohort study enrolled 27 newly diagnosed pediatric HB with lung metastases who received the modified SIOPEL-4 protocol at Shanghai Children′s Medical Center, Shanghai Jiao Tong University School of Medicine, and Shanghai Children′s Hospital between January 2020 to December 2023. Clinical characteristics, lung response rates to induction chemotherapy, treatment outcomes, prognostic factors and sever chemotherapy toxicities at different stages were analyzed. Survival analysis was performed by Kaplan-Meier method. Univariate prognostic analysis was conducted by Log-Rank test.Results:Of the 27 patients, there were 17 males and 10 females, with the age of 21 (15, 33) months. During the follow-up of 31 (12, 45) months for 17 continuous complete remission patients, 4 cases disease progression (2 cases death) and 6 cases relapse were observed. The 2-year event free survival (EFS) and overall survival (OS) rate was (58±11)% and (89±7)%, respectively. All the 27 patients had response to block 1-3 induction chemotherapy (cisplatin+doxorubicin), with 14 cases (52%) achieving complete response and 13 cases (48%) achieving partial response of lung metastatic lesions, the 2-year EFS rate was (81±12)% and (34±14)%, respectively ( χ 2=6.76, P=0.009), the 2-year OS rate was 100% and (79±13)%, respectively ( χ2=2.12, P=0.145). Patients with caudate lobe tumors or ≥10 pulmonary metastatic nodules had significantly lower EFS rates ( χ2=5.36, 7.84, P=0.021, 0.005, respectively). The incidence of grade 3/4 neutropenia after block 1-3 induction chemotherapy, CD (carboplatin+doxorubicin), and VI (vincristine+irinotecan) consolidation chemotherapy was 90% (73/81), 75% (58/77), and 31% (11/35), respectively. The incidence of grade 3/4 thrombocytopenia was 77% (62/81), 69% (53/77), and 14% (5/35), respectively. The incidence of grade 3/4 infections was 64% (52/81), 25% (19/77), and 20% (7/35), respectively. The differences between the groups were statistically significant ( χ2=43.51, 42.69, 33.00, all P<0.001). Two patients (10%) of the 20 evaluable patients for ototoxicity occurred grade 3 and higher hearing impairment, with 1 patient requiring a hearing aid. Conclusions:The modified SIOPEL-4 regimen shows good preliminary efficacy and safety in treating pediatric HB with lung metastases. The prognosis for patients with residual lesions in the lungs after induction chemotherapy needs to be improved. Attention should be given to the ototoxicity induced by high-dose cisplatin chemotherapy.

Objective To investigate the regulatory role of miR-93/MFN2 axis in pulmonary fibrosis associated with acute respiratory distress syndrome(ARDS)through endoplasmic reticulum stress(ERS)and mitochondrial function.Methods An in v itro model of ARDS-induced pulmonary fibrosis was established by treating human embryonic lung fibroblasts(HFL-1)with li-popolysaccharide(LPS).Four experimental groups were employed in functional validation:negative control inhibitor(inhibitor NC),miR-93 inhibitor,miR-93 inhibitor+scrambled control siRNA(si-NC),and miR-93 inhibitor+MFN2-targeting siRNA(si-MFN2).Collagen Ⅰ(COLⅠ)secretion was assesed by ELISA and Western blotting;MFN2 and miR-93 expressions were detec-ted by qRT-PCR;Cell proliferation was assessed by CCK-8 assay;Apoptosis was evaluated by flow cytometry;ERS marker(Bip/GRP78,IRE1)levels and mitophagy protein Beclin-1 were detecetd by Western blotting.The miR-93-MFN2 interaction was confirmed via dual-luciferase assays.Results Compared with control group,COL Ⅰ secretion in HFL-1 cells was signifi-cantly increased in LPS group(P＜0.01 vs.control),validating the in vitro pulmonary fibrosis model.Compared to the inhibitor NC group,the miR-93 inhibitor group exhibited significantly upregulated MFN2 expression,decreased HFL-1 cell proliferation,increased apoptosis,and reduced COLⅠ secretion(all P＜0.01).MFN2 was confirmed as a direct target of miR-93 by dual-lu-ciferase assays.Compared with inhibitor NC group,levels of ERS markers(Bip/GRP78,IRE1)were downregulated,and the mi-tophagy marker Beclin-1 was upregulated in miR-93 inhibitor group(P＜0.01).These effects were rescued after co-transfection with miR-93 inhibitor and si-MFN2.Compared to the miR-93 inhibitor group alone,the miR-93 inhibitor+si-MFN2 group showed attenuated suppression of cell proliferation,increased COLⅠ secretion,upregulated ERS markers(Bip/GRP78,IRE1),and downregulated Beclin-1 expression.Conclusion miR-93 exacerbates ARDS-associated pulmonary fibrosis by directly targe-ting and suppressing MFN2.This disruption likely compromised mitochondria-associated ER membrane(MAM)homeosta-sis.Targeting themiR-93/MFN2 axis alleviates fibrosis by attenuating ERS and promoting mitophagy,highlighting its potential as a therapeutic strategy.

Objective To investigate the current status of family resilience of children with cancer and analyze its influencing factors,to provide a basis for medical staff to formulate intervention plans.Methods Using a convenient sampling method,children with cancer who were hospitalized in 2 tertiary hospitals in Henan Province from January to April 2024 were selected for the survey.A general information questionnaire,family resilience assessment scale,quality of life family version,ZBI caregiver burden interview,and social support rating scale were used to understand the current status of family resilience of children with cancer and to explore the related influencing factors by univariate analysis and multiple stepwise linear regression analysis.Results A total of 280 questionnaires were distributed and 265 valid questionnaires were recovered,with a valid questionnaire recovery rate of 94.64％.The total score of family resilience for primary caregivers of children with cancer was(185.63±30.66).The multiple stepwise linear regression analysis results showed that the children's self-care ability,caregiver's work status,family care burden,and social support level were the influencing factors for family resilience of children with cancer(P＜0.05),and the explanatory variance was 51.3％.Conclusion The family resilience of children with cancer is at a medium level.The worse the children's self-care ability and the heavier the family care burden,the worse the family resilience;the caregiver's work status and good social support are helpful for the family resilience of children with cancer.Healthcare workers should develop intervention programs to address these factors to enhance the family resilience of children with cancer.
