Objectives:To investigate the physical growth status of pediatric patients with transfusion-dependent thalassemia (TDT) and analyze the effects of treatment-related and socioeconomic factors on physical growth.Methods:Based on the specialized thalassemia database from gene therapy clinical research at the Institute of Hematology & Hospital of Blood Diseases, Chinese Academy of Medical Sciences & Peking Union Medical College, we collected data on height and weight development, family economic status, and medical records of 338 pediatric patients with TDT from October 2023 to May 2024. The length/height-for-age and body mass index (BMI) -for-age were classified based on the Growth Standard for Children under 7 Years of Age, Standard for Height Level Classification among Children and Adolescents Aged 7-18 Years, and Dietary Guidelines for Chinese Residents. Logistic regression analysis was conducted to assess the effects of family economic status and disease-related treatment on length/height-for-age and BMI-for-age.Results:Among the 338 patients, 118 were children and 220 were adolescents (192 males and 146 females), with a median age of 12 years (range: 0.8-18) and a median diagnosis duration of 10.3 years (range: 0.5-17.9). Subtypes included α-thalassemia [21 cases (6.2%) ], β-thalassemia [288 cases (85.2%) ], and combined αβ-thalassemia[29 cases (8.6%) ]. The monthly household income of patients was concentrated in 3 000-5 000 yuan (39.9%) and 5 001-10 000 yuan (34.9%), whereas 67.2% of the families had monthly medical expenses of <3 000 yuan. Of the patients, 75.5% received their first transfusion before 1 year of age. The proportions of children and adolescents with pretransfusion hemoglobin (HGB) of ≤70 g/L were 4.2% and 6.4%, respectively. Adolescents demonstrated significantly higher rates of transfusion frequency of <4 weeks/session, monthly red blood cell infusion of >2 U, serum ferritin (SF) of ≥5 000 μg/L, iron chelation therapy, and splenectomy compared with children (all P<0.05). Of the 338 patients, 26.0%, 22.8%, and 8.9% demonstrated stunted growth, underweight, and concurrent stunted growth with underweight, respectively. No significant difference was observed in the stunted growth rates between children (22.9%) and adolescents (27.7%) ( P=0.402). However, the underweight rate in adolescents (26.8%) was significantly higher than that in children (15.3%) ( P=0.023). The multivariate analysis determined the following risk factors for stunted growth: monthly household income of <10 000 yuan (5 001-10 000 yuan: OR=5.49, 95% CI: 1.48-35.76; 3 000-5 000 yuan: OR=6.87, 95% CI: 1.88-44.60; <3 000 yuan: OR=9.29, 95% CI: 2.20-64.77), pretransfusion HGB of ≤70 g/L ( OR=3.25, 95% CI: 1.07-10.18), and SF of ≥5 000 μg/L ( OR = 3.04, 95% CI: 1.20-7.70). Longer diagnostic duration was associated with underweight ( OR=1.10, 95% CI: 1.01-1.20) . Conclusions:Children and adolescents with TDT with pretransfusion SF of ≥5 000 μg/L, HGB of ≤70 g/L, low monthly household income, or longer diagnosis duration were significantly more likely to experience delayed physical growth.

Cardiac surgery patients often present with multiple comorbidities,the risk of periop-erative complications and the complexity of postoperative rehabilitation have significantly increased,posing higher demands on comprehensive perioperative management.Preoperative exercise pre-reha-bilitation,as a multidisciplinary collaborative intervention strategy,has been demonstrated to signifi-cantly improve the clinical prognosis of patients undergoing elective cardiac surgery by enhancing their cardiopulmonary function,muscle strength,and overall physiological functional reserve,thereby in-creasing the body's tolerance to surgical stress.Although phase-specific research achievements have been made domestically and internationally in the field of exercise pre-rehabilitation,its standardized implementation and clinical translation on a global scale still face numerous obstacles,necessitating systematic review and in-depth exploration.Therefore,this study aimed to conduct a systematic re-view of the intervention protocols,clinical efficacy,safety,and feasibility of preoperative exercise pre-rehabilitation in patients undergoing elective cardiac surgery,with the goal of providing theoretical evidence and practical references for optimizing perioperative management pathways and promoting the implementation of enhanced recovery after surgery concepts.

ObjectiveTo evaluate the efficacy and safety of traditional Chinese exercises (TCE) in patients with diabetic peripheral neuropathy (DPN) and to recommend best practices for using TCE to improve neurological function, glycemic control, and psychological well-being.MethodsNine databases were searched from the inception to October 2024. Effect relationships were assessed using meta-analysis with Stata 17, and the methodological quality and certainty of the evidence were evaluated using standard tools.ResultsTwelve studies comprising three study designs (nine randomized controlled, one quasi-experimental controlled, and two single-arm clinical trials), were identified. Compared with usual care, TCE improved various indicators and enhanced the nerve conduction velocities of the peroneal motor (mean difference [MD] = 3.86 m/s, 95% confidence interval [CI]: 0.38 to 7.34, P = .03), sural sensory (MD = 4.15 m/s, 95% CI: 0.68 to 7.63, P = .02), median motor (MD = 3.84 m/s, 95% CI: 2.14 to 5.54, P .001), and median sensory nerves (MD = 6.14 m/s, 95% CI: 4.54 to 7.74, P .001). TCE practices also reduced glycosylated hemoglobin level (MD = −0.59%, 95% CI: −0.91 to −0.27, P .001) and fasting blood glucose (standardized mean difference [SMD] = −1.08, 95% CI: −1.79 to −0.37, P .001). The overall quality of evidence was very low.ConclusionThe results indicate that TCE therapy improves certain outcomes in patients with DPN. Although the optimal type, intensity, frequency, and duration of TCE interventions are uncertain, these preliminary findings suggest that TCE should be further studied as a potentially affordable and effective treatment for DPN.

Objective To explore the effect and preliminary mechanism of the plant-derived immunostimulatory molecule,ophiopogonin,on enhancing the immune response of a subunit vaccine with the receptor-binding domain(RBD)of coronavirus spike protein as the antigen.Methods CCK-8 assay was used to determine the cytotoxicity of ophiopogonin D'(OPD')on bone marrow-derived dendritic cells(BMDCs).Female Balb/c mice were randomly divided into RBD,RBD/OPD',RBD/Alum,and control groups.The immunization dose was 5 μg of antigen per mouse and 100 μg of adjuvant per mouse,and immunization was carried out according to the intramuscular injection immunization procedure on days 0,21,and 42.The titers of specific IgG and its subtype antibodies were detected by ELISA.The cytokine levels in the supernatant of splenocytes were detected using ELISA.The number of splenocytes secreting IFN-γ was detected by ELISpot.Laser confocal microscopy was employed to observe the uptake of antigen by BMDCs.The phagocytic ability of BMDCs for antigen was quantitatively analyzed by flow cytometry.The mechanism of its enhanced immune effect was preliminarily explored using transcriptomics technology combined with bioinformatics research.Results When the concentration of OPD'was less than 5 μg/mL,the survival rate of BMDCs was 100%.After a single intramuscular injection in mice,except for a slight decrease in body weight,the other biochemical indicators were within corresponding normal ranges.After intramuscular injection immunization of the vaccine,the titers of serum-specific IgG,IgG1,and IgG2a in the RBD/OPD'group were significantly higher than those in the RBD group(P<0.05).Compared with the RBD group,the RBD/OPD'group induced a high-level Th1 cell immune response of IL-1β,TNF-α,and IFN-γ(P<0.01)and had more lymphocytes secreting IFN-γ(P<0.001).Laser confocal microscopy displayed that BMDCs took up more antigens after OPD'treatment,which was further confirmed with flow cytometry in quantitative analysis on antigen uptake rate(P<0.01).Transcriptomics results indicated that there was more significant enrichment of the PPAR signaling pathway in the RBD/OPD'group than the RBD group,suggesting that OPD'may activate the PPAR signaling pathway to exert its adjuvant effect.Conclusion OPD'effectively enhances the immune response of the RBD subunit vaccine,and its action mechanism may be related to the activation of the PPAR signaling pathway.

Objective To investigate the effect of electroacupuncture(EA)on the behaviors of lipopolysaccharide(LPS)-induced depression-like mice and explore the potential molecular mechanism of the antidepressant effect of EA using transcriptomics sequencing technology.Methods Thirty-six male specific pathogen-free-grade C57BL/6J mice were divided into the normal,the model,and the EA groups using the random number table method,with 12 mice per group.The EA group received a daily 20-minute EA at the"Baihui"and"Yintang"acupoints for 7 days.After 7 days of EA treatment,1.5 mg/kg LPS was injected intraperitoneally into the model and EA groups,whereas the normal group received an injection of an equal volume of saline solution.Depressive behaviors were assessed using the open-field test,tail-suspension test,and other relevant tests.Pathologic morphology of the hippocampus tissue was determined using hematoxylin-eosin staining.Transcriptomics technology was used to identify differentially expressed genes in the hippocampus,and bioinformatics analysis was performed.Real-time fluorescence quantitative PCR was performed to detect the mRNA expressions of hematopoietic cell kinase(Hck),adhesion G protein-coupled receptor E1(Adgre1),Toll-like receptor 2(Tlr2),and Gm49037 in the hippocampus.Results Compared to the normal group,mice in the model group exhibited a decrease in total travel distance,central travel distance,center area time(P＜0.01),as well as an increase in tail-suspension immobility time(P＜0.05).Hippocampal neurons were loosely arranged,and some neurons had blurred boundaries.Compared to the model group,mice in the EA group showed an increase in open-field total travel distance,central travel distance,center area time(P＜0.05),as well as a decrease in tail-suspension immobility time(P＜0.01);Additionally,hippocampal neurons were more tightly arranged,exhibiting clearer morphology and structure.Transcriptomic analysis revealed that 779 differentially expressed genes were identified in the model group compared to the normal group,whereas 172 genes differed between the EA and model groups.Nineteen genes were upregulated in the model group but downregulated in the EA group,and ten genes were down-regulated in the model group but up-regulated in the EA group.Gene Ontology Functional Analysis indicated that these genes primarily function in immune responses,Toll-like receptor activity,cell surface receptor signaling pathways,and interleukin-10 production.Kyoto Encyclopedia of Genes and Genomes pathway analysis revealed enrichment in inflammation-related pathways,including Toll-like receptor signaling pathway and tumor necrosis factor signaling pathway.Compared to the normal group,Hck,Adgre1,and Tlr2 mRNA expressions were elevated in the model group(P＜0.01),whereas there was a decrease tendency for Gm49037 mRNA expression and there was no significant difference(P＞0.05);compared to the model group,Hck,Adgre1,and Tlr2 mRNA expressions were decreased in the EA group(P＜0.05),whereas there was an increase tendency for Gm49037 mRNA expression and there was no significant difference(P＞0.05).Conclusion EA alleviated depressive-like behavior and pathological damage in the hippocampus in LPS-induced mice,which may be related to attenuating hippocampal inflammatory pathways,and Hck,Adgre1,and Tlr2 genes may be the potential targets for its effect.

Objective To explore the optimal ratio of Baitong decoction based on efficacy,clarify its spectrum-effect relationship,and identify its potential quality markers.Methods An ulcerative colitis(UC)model in mice was established using dextran sulfate sodium.The efficacy of Baitong decoction with varying drug ratios was assessed by evaluating the apparent score,pathological score and inflammatory factor changes of UC in each group of experimental animals.The fingerprints of Baitong decoction with different ratios were established by high performance liquid chromatography(HPLC),and the relationship between the content of each substance and its efficacy was analyzed by partial least squares regression to determine the potential quality markers of Baitong decoction.Results Baitong decoction was most effective in relieving ulcerative colitis when the mass ratio of Fuzi,Ganjiang and Congbai was 1∶2∶2.The fingerprinting identified 14 common peaks across 7 ratios,with 9 peaks were found to be associated with the remission of ulcerative colitis by partial least squares regression analysis.Conclusion The optimal ratio of Fuzi,Ganjiang and Congbai for treating UC is 1∶2∶2.The spectrum-effect relationship analysis suggested that the quality markers of Baitong decoction may be the substances represented by peak 2(benzoylaconine),3,5,6,8(mesaconine),9(aconitine),10(hypaconitine),13(10-gingerol)and 14.

Objective To investigate the antibacterial effect and its preliminary mechanism of lavender essential oil on multi-drug resistant Acinetobacter baumannii.Methods Micro-dilution method was used to determine the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC)of lavender essential oil against multi-drug resistant Acinetobacter baumannii,and bactericidal kinetic study was employed to determine the onset and maintenance time of lavender essential oil.Meanwhile,the promoting and therapeutic effects of lavender essential oil on wound healing were observed in a mouse model of infection.Subsequently,crystal violet staining was used to determine the inhibition and clearance of multi-drug resistant Acinetobacter baumannii biofilm by lavender essential oil,and laser confocal microscopy was utilized to observe the survival of bacteria in biofilms.NanoDrop instrument was utilized to quantify the leakage of bacterial DNA nucleic acid and protein after intervention with 3 and 6 mg/mL lavender essential oil,and the leakage of bacterial potassium ion was measured by potassium ion test kit.Proteomics technology combined with bio-informatics were applied to explore the action mechanism of lavender essential oil against multi-drug resistant Acinetobacter baumannii.Results The MIC and MBC of lavender essential oil were both 6 mg/mL,which could kill almost all multi-drug resistant Acinetobacter baumannii at the time point of 120 min,and showed an obvious dose-and time-dependent manner.The overall animal model evaluation showed that both 3 and 6 mg/mL lavender essential oil could promote wound healing,and the curative effect was obvious.Further studies confirmed that 3 mg/mL lavender essential oil had a certain biofilm inhibitory effect on multi-drug resistant Acinetobacter baumannii,and 6 mg/mL also had a certain biofilm clearance effect under the same conditions.Meanwhile,when incubated at 37℃ for 1 h,the dose of 3 mg/mL could increase the leakage of DNA nucleic acid and protein,and significantly promote the efflux of potassium ions.Proteomic analysis suggested that the antibacterial effect of lavender essential oil may be related to affecting the oxidorereductase activity and cell metabolic process of multi-drug resistant Acinetobacter baumannii,and interfering with the biosynthesis of cell wall/membrane/envelope and other structures.Conclusion Lavender essential oil at 3 mg/mL can play an antibacterial effect against multi-drug resistant Acinetobacter baumannii,and its mechanism may be related to the destruction of bacterial biofilm and interference with bacterial metabolism.

Objective: To evaluate the effect of Tai Chi and Qigong on patients with lumbar disc herniation (LDH). Methods: Relevant data were retrieved from nine English and Chinese databases, including Cochrane Library, PubMed, and Wanfang Data, etc. from inception to June 2024. All published randomized controlled trials assessing the effect of Tai Chi and Qigong on visual analog scale (VAS), Japanese Orthopedic Association (JOA) score, and other health indicators in participants with LDH compared to usual medical care or other treatments were included. Grey literature, trials involving the pushing of hands (Tui Shou) or Tai Chi with weapons, and trials with co-interventions (Tai Chi/Qigong plus another treatment) were excluded. Methodological quality was analyzed using the Cochrane risk of bias tool, and evidence quality was assessed using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) tool. Results: Fourteen trials (954 patients) were included in this study. Tai Chi and Qigong were associated with lower VAS pain scores (standardized mean difference −0.55, 95% confidence interval [CI] −0.95 to −0.15, P = .01), higher JOA scores (mean difference [MD] 4.40, 95% CI 2.62 to 6.18, P < .001) and straight leg raise test results (MD 9.40°, 95% CI 7.64 to 11.15, P < .001) in patients with LDH. Furthermore, compared with usual care, Tai Chi and Qigong showed enhanced effects on pain and JOA scores. When compared to other exercises or massage, the effect on pain scores was similar but that on JOA scores was significant. Conclusions Tai Chi and Qigong may have favorable effects on VAS pain and JOA scores compared with usual care, and on JOA scores compared with other exercises or massage in patients with LDH. Given the overall poor quality of the evidence, the results of current study should be interpreted cautiously.
