Objective To investigate the antibody levels of measles, rubella and mumps among healthy residents in Fengtai District, Beijing, and to provide reference for further improving the level of immunization coverage.Methods A total of 242 healthy people who had continuously resided in Fengtai District for more than six months were randomly selected. Blood samples were collected for quantitative detection of IgG antibodies against measles, rubella and mumps by indirect ELISA.Results Among the 242 people surveyed, the positive rates of measles, rubella and mumps antibodies were 76. 45%, 89. 67%and 75. 62%, and the geometric mean concentrations(GMCs) were 739. 97 IU/L, 35. 87 IU/mL and 43. 01 RU/mL,respectively. There was no significant difference in the positive rates of measles, rubella, and mumps antibodies between males and females(χ~2= 0. 659, 0. 173 and 0. 046, respectively, P > 0. 05). There was no significant difference in the positive rates of measles, rubella, and mumps antibodies between this city and floating household registrations(χ~2= 1. 859, 0. 045 and 1. 098, respectively, P > 0. 05). However, the positive rates of measles, rubella, and mumps antibodies between different age groups were statistically significantly different(χ~2= 31. 324, χ~2_(fisher)= 28. 650, χ~2= 24. 817, P < 0. 05), and the positive rates of three antibodies were statistically significantly different among different immunization times(χ~2= 14. 315, χ~2_(fisher)=21. 766, χ~2= 17. 764, P < 0. 05).Conclusion The levels of measles, rubella and mumps antibodies among healthy individuals in Fengtai District remain to be further enhanced. In the future, routine vaccination services should be continuously strengthened, and women of childbearing age should be advocated to receive measles-mumps-rubella vaccine, so as to further enhance the level of immunization coverage.

OBJECTIVE: To explore the prenatal and postnatal phenotypes of 22q11.2 microdeletion syndrome (22q11.2DS) and enhance clinical understanding of this condition. METHODS: Data were collected from 86 fetuses diagnosed with 22q11.2DS at four prenatal diagnostic centers across China between January 2014 and August 2025. Prenatal imaging findings, pregnancy outcomes, and postnatal conditions were analyzed. RESULTS: Among the 86 fetuses, complete ultrasound data were available for 65 cases. Cardiovascular abnormalities were observed in 42 cases, thymic hypoplasia or aplasia in 7 cases, urinary system anomalies in 6 cases, nuchal translucency (NT) thickening in 7 cases, butterfly vertebrae, clubfoot, omphalocele and diaphragmatic hernia in 1 case each, cleft lip and palate in 2 cases, and ultrasound soft markers in 13 cases. The parents of 9 fetuses opted to continue with the pregnancy. Among these, 6 showed no significant ultrasound abnormalities and no related phenotypes postnatally, while the remaining 3 exhibited ultrasound anomalies with postnatal manifestations including developmental delay, immunodeficiency, and cardiac defects. CONCLUSION Fetuses with 22q11.2DS may exhibit various ultrasound abnormalities in multiple systems before and after birth. In addition to cardiovascular anomalies, they may also present with thymic hypoplasia or aplasia, thickened NT, and urinary abnormalities. Fetuses with thickened NT or thymic anomalies should be closely monitored, and thymic assessment should be included in routine prenatal imaging evaluations. For fetuses with 22q11.2DS who show no ultrasound abnormalities, the risk of developing severe phenotypes after birth is relatively low, but occult palate clefts and psychiatric disorders cannot be ruled out. Due to limitations in sample size and follow-up duration, above conclusions require further validation through large-scale prospective studies.

OBJECTIVE: To investigate the impact of different iterative cone beam CT (iCBCT) scanning beam currents from a ring-mounted linac on synthetic CT image quality for lung adaptive radiotherapy under lung scanning protocol. METHODS: The CIRS lung motion phantom was configured to simulate conventional respiratory motion pattern, followed by 4D-CT simulation. After transferring the radiotherapy plan to the ring-mounted Halcyon 3.0 linac, three groups of typical iCBCT scans with different beam currents [ I _low (160 mA), I _middle (282 mA), and I _high (491 mA)] were performed and corresponding image reconstructions were completed. Synthetic CT (sCT) images were subsequently obtained based on the deformable registration algorithm. RESULTS: Compared to the corresponding CBCT images, the sCT images exhibited a significant reduction in artifacts. The fine structure of the planning CT (pCT) image was preserved for sCT images corresponding to different scanning beam currents, with Dice similarity coefficients exceeding 0.90 for all cases. CONCLUSION The image quality of sCT corresponding to different iCBCTs is comparable to that of pCT, and changes in iCBCT beam parameters have a negligible impact on sCT image quality. Taking into account both image quality and imaging dose factors associated with the beam currents, iCBCT with a lower beam current on the ring-mounted Halcyon linac offers greater clinical value in lung adaptive radiotherapy.

Mycophenolic acid (MPA), the active moiety of both mycophenolate mofetil (MMF) and enteric-coated mycophenolate sodium (EC-MPS), serves as a primary immunosuppressant for maintaining solid organ transplants. Therapeutic drug monitoring (TDM) enhances treatment outcomes through tailored approaches. This study aimed to develop an evidence-based guideline for MPA TDM, facilitating its rational application in clinical settings. The guideline plan was drawn from the Institute of Medicine and World Health Organization (WHO) guidelines. Using the Delphi method, clinical questions and outcome indicators were generated. Systematic reviews, Grading of Recommendations Assessment, Development, and Evaluation (GRADE) evidence quality evaluations, expert opinions, and patient values guided evidence-based suggestions for the guideline. External reviews further refined the recommendations. The guideline for the TDM of MPA (IPGRP-2020CN099) consists of four sections and 16 recommendations encompassing target populations, monitoring strategies, dosage regimens, and influencing factors. High-risk populations, timing of TDM, area under the curve (AUC) versus trough concentration (C₀), target concentration ranges, monitoring frequency, and analytical methods are addressed. Formulation-specific recommendations, initial dosage regimens, populations with unique considerations, pharmacokinetic-informed dosing, body weight factors, pharmacogenetics, and drug‍-‍drug interactions are covered. The evidence-based guideline offers a comprehensive recommendation for solid organ transplant recipients undergoing MPA therapy, promoting standardization of MPA TDM, and enhancing treatment efficacy and safety.

Objective:To compare the efficacy of three-dimensional visualization-assisted intermuscular versus conventional intermuscular cervical expansive open-door laminoplasty (CEOL) in the treatment of cervical spinal cord injury without fracture or dislocation (CSCIWFD).Methods:A retrospective cohort study was conducted to analyze the clinical data of 58 patients with CSCIWFD admitted to Zhengzhou Orthopedic Hospital from October 2021 to January 2024, including 39 males and 19 females, aged 36-77 years [(52.9±8.9)years]. Among them, 26 patients were treated with three-dimensional visualization-assisted intermuscular CEOL (three-dimensional visualization group), while 32 patients were treated with conventional intermuscular CEOL (conventional intermuscular group). All patients were treated with CEOL in 4 segments (C 3-C 6), comprising 104 surgical segments in the three-dimensional visualization group and 128 in the conventional intermuscular group. The following outcomes were compared between the two groups, including the operative duration, intraoperative blood loss, accuracy rate of open-door and hinge placement at the surgical levels, visual analogue scale (VAS) of the neck and shoulder and Japanese Orthopedic Association (JOA) score preoperatively, at 1 week, 1 month, 3 months, 6 months postoperatively and at the last follow-up, American Spinal Injury Association (ASIA) impairment scale preoperatively and at the last follow-up, and postoperative complication rate. Results:All patients were followed up for 12-24 months [(17.5±3.1)months]. The operative duration and intraoperative blood loss were (117.0±12.3)minutes and (151.3±30.9)ml in the three-dimensional visualization group, which were shorter or less than (131.9±15.0)minutes and (184.7±42.9)ml in the conventional intermuscular group ( P<0.01). The accuracy rate of open-door and hinge placement at the surgical levels was 94.2% (98/104) in the three-dimensional visualization group, significantly higher than 83.6% (107/128) in the conventional intermuscular group ( P<0.05). The VAS scores of the neck and shoulder preoperatively, at 1 week, 1 month, 3 months, 6 months postoperatively, and at the last follow-up were 6.0(5.0, 7.0)points, 3.5(3.0, 4.0)points, 3.0(2.0, 3.0)points, 2.0(1.0, 3.0)points, 2.0(1.0, 2.3)points, and 2.0(1.0, 2.0)points in the three-dimensional visualization group, which were not statistically different from 5.0(4.3, 6.8)points, 4.0(3.0, 4.0)points, 3.0(2.0, 3.0)points, 2.0(1.3, 2.0)points, 2.0(1.0, 2.8)points, and 2.0(1.0, 2.0)points in the conventional intermuscular group ( P>0.05). The VAS scores of the neck and shoulder in the two groups were significantly decreased at 1 week, 1 month and 3 months postoperatively from the preoperative values ( P<0.05), while they were stabilized at 6 months postoperatively and at the last follow-up compared with those at 3 months postoperatively, with no significant difference among them ( P>0.05). The JOA scores were (8.1±2.8)points, (10.0±2.6)points, (10.5±2.6)points, (11.6±2.3)points, (12.7±2.3)points, and (13.7±2.4)points in the three-dimensional visualization group, which were not statistically different from (8.8±2.2)points, (10.3±2.1)points, (10.8±2.0)points, (12.0±2.0)points, (12.9±2.0)points, and (13.8±2.1)points in the conventional intermuscular group ( P>0.05). The JOA scores of the two groups showed continuous improvement at 1 week, 1 month, 3 months, 6 months postoperatively and at the last follow-up in comparison with the preoperatively values ( P<0.05). Although no significant difference was observed between the two groups in ASIA grade preoperatively and at the last follow-up ( P>0.05), the ASIA grade at the last follow-up was significantly improved compared with that before surgery in both groups ( P<0.05). The postoperative complication rate was 12% (3/26) in the three-dimensional visualization group, significantly lower than 38% (12/32) in the conventional intermuscular group ( P<0.05). Conclusion:Compared with the conventional intermuscular approach, the three-dimensional visualization-assisted intermuscular CEOL offers advantages in reducing surgical trauma, improving surgical precision, and lowering the postoperative complication rate in the treatment of CSCIWFD.

Objective:To investigate the clinical efficacy of haploidentical high-dose in vitro non-T-cell-depleted peripheral blood hematopoietic stem cell transplantation (haplo-HDPSCT) in treating adult patients with Ph + acute lymphoblastic leukemia (Ph + ALL) . Method:This retrospective analysis was conducted on the clinical efficacy of 25 adult patients with Ph + ALL who underwent haplo-HDPSCT from July 2011 to June 2022 at our hospital. Results:This study included 25 patients with a median age of 27 (16-61) years, consisting of 12 males and 13 females. CR1 and ≥CR2 before transplantation were found in 23 and 2 cases, positive and negative minimal residual lesions were observed in 8 and 17 cases, and myeloablative conditioning and reduced-intensity conditioning were reported in 21 and 4 cases, respectively. Hematopoietic function was restored in all 25 patients after stem cell infusion. Of the 25 patients who underwent transplantation, 16 developed acute graft-versus-host disease (aGVHD). The cumulative incidence rates of Ⅱ-Ⅳ and Ⅲ-Ⅳ aGVHD were (40.4±11.3) % and (4.8±4.6) %, respectively. Four patients experienced relapse after transplantation, the cumulative relapse rates at 1 and 2 years after transplantation were (4.0±3.9) % and (14.5±7.9) %, respectively. The 2-year overall survival rate after transplantation was (81.3±8.5) % and the disease-free survival rate was (77.1±9.1) %.Conclusion:This study reveals that the unique haplo-HDPSCT protocol achieves good clinical efficacy in Ph + ALL treatment.

Objective: To systematically evaluate the association between maternal adverse childhood experiences (ACEs) and offspring social behavior, so as to provide a theoretical basis for further research on intergenerational social behavioral development. Methods: Relevant research literature about maternal ACEs and the development of children s maladaptive social behaviors were collected, from China National Knowledge Infrastructure (CNKI), VIP, Wanfang, SinoMed, PubMed, Web of Science, Cochrane Library, Embase and SpringLink databases, covering the period from the inception of each database to May 2025. The Chinese database matched and searched through three groups of keywords: "Pregnant women" "Mothers" and "Women"; "Bad childhood experience" "Bad early experience" and "Bad adolescent experience"; "Children" "Teenagers" "Children s behavior" "Children s development" "Teenagers behavior" "Internalized behavior" and "Externalized behavior". The English database was searched by three groups of keywords: "Female" "Pregnant women" "Mothers"; "Adverse childhood experiences" "Adverse early childhood experiences" "Adverse experiences of adolescent"; "Child behavior" "Child development" "Adolescent behavior" "Internalized behaviors" "Externalized behaviors". The selected literature was evaluated for quality and data extraction, with OR and 95% CI as effect indicators. Stata 16.0 software was used for heterogeneity testing, subgroup analysis, and publication bias analysis. Results: A total of 14 studies involving 64 302 mother-child pairs were included. The Meta analysis results showed a significant correlation between maternal ACEs and both offspring maladaptive internalized behaviors ( OR=1.75, 95%CI=1.42-2.15, P <0.01) and externalized behaviors ( OR=1.82, 95%CI=1.51-2.20, P <0.01). The results of subgroup analyses showed that in different regions[internalized behaviors:domestic, foreign OR (95% CI )=2.03(1.49-2.76), 1.55(1.19-2.03); externalized behaviors: domestic, foreign OR (95% CI )=2.41(1.52-3.82), 1.65(1.36-2.01)], study type[internalized behaviors: cohort study, cross sectional study OR (95% CI )=1.64(1.34-2.00), 1.85(1.30-2.65); externalized behaviors: cohort study, cross sectional study OR (95% CI )=1.76(1.46-2.12), 2.12(1.40-3.20)], sample size [internalized behaviors: ≥4 000, <4 000 pairs OR (95% CI )=1.69(1.13-2.55), 1.77( 1.41 -2.24); externalized behaviors: ≥3 000, <3 000 pairs OR (95% CI )=1.72(1.37-2.17), 2.13(1.44-3.15)], there were significant and positive association between mothers ACEs and children s internalizing and externalizing behaviors (all P <0.05). Conclusion A substantial positive association exists between maternal ACEs and the development of offspring maladaptive internalized and externalized behaviors, but the result needs to be continued to be validated by more research.

ObjectiveTo evaluate the efficacy of Sanhua essential oil inhalation as aromatherapy in patients with breast cancer-related depression.MethodsIn total, 144 patients with breast cancer-related depression who underwent postoperative chemotherapy were recruited. The participants in the control group (n = 52) were offered a placebo (sunflower oil) daily, whereas those in the essential oil group (n = 52) were administered Sanhua essential oil. This study evaluated depression improvement, Hamilton Depression Scale score, scores of symptoms in traditional Chinese medicine (TCM), Pittsburgh Sleepiness Quotient Index score, incidence of nausea and vomiting, and signal changes on functional magnetic resonance imaging.ResultsDepression improved by 48.1% and 21.2% in the essential oil and control groups, respectively (P = .010). The Hamilton Depression Scale score (P = .017), scores for symptoms in TCM (P = .002), and the incidence of nausea and vomiting in the acute and delayed phases were lower in the essential oil group than in the control group (nausea in the acute phase, P = .017; nausea in the delayed phase, P = .039; vomiting in the acute phase, P = .008; vomiting in the delayed phase, P = .081). The Pittsburgh Sleepiness Quotient Index score was lower in the essential oil group than in the control group (P = .005). Significant differences existed between the two groups in the left superior parietal gyrus, right precuneus, left dorsolateral superior frontal gyrus, and right precentral gyrus according to functional connectivity on functional magnetic resonance imaging.ConclusionInhalation of Sanhua essential oil alleviated depression in patients undergoing chemotherapy for breast cancer, improved sleep quality, relieved TCM symptoms, reduced nausea and vomiting, and regulated activities in the brain regions.

Objective To investigate whether microRNA-21-5p(miR-21)plays a protective role in hyperoxia-induced acute lung injury(HALI)by regulating ferroptosis through the STAT3/P53/SLC7A11 axis.Methods The interaction between STAT3 and P53 was analyzed by co-immunoprecipitation(Co-IP).Fifty 9-week-old male C57BL/6J mice were randomly divided into normoxia(Control)group,HALI group,miR-21 overexpression(miR-21)group,STAT3 inhibitor(HY-13818)group,and ferrostatin-1(Fer-1)group.After the mice from the miR-21 group received miR-21-5p AAV6 or empty vector via tracheal catheter instillation,the animals were then monitored for 3 weeks.The HY-13818 group was intraperitoneally injected with HY-13818(10 mg/kg)3 times weekly for 2 weeks.The Fer-1 group received 0.8 mg/kg ferrostatin-1 via tail vein injection once daily for 2 consecutive days during modeling.The HALI model was established by exposure to>90%oxygen.After 48 h of hyperoxia,blood samples were collected via orbital sampling for RT-PCR analysis of miR-21 expression.Lung tissues were harvested for wet/dry weight ratio and assessment of histopathological changes via HE staining for lung injury score.Activity of superoxide dismutase(SOD)and contents of malondialdehyde(MDA),Fe2?,glutathione(GSH),and reactive oxygen species(ROS)were measured using photocolorimetry,spectrophotometry and fluorometry.Western blotting was used to evaluate the protein expression of STAT3,P53,SLC7A11,and GPX4.Results The results of Co-IP showed that STAT3 could bind to P53.The HALI group exhibited obviously destroyed alveolar structure,disordered arrangement,thickened interval,with a large number of infiltrated neutrophils and collapsed alveoli,and had significantly increased pathological score of lung injury and ratio of lung Wwet/Ddry weight when compared with the Control group(P<0.05).In the miR-21 group,HY-13818 group and Fer-1 group,the severity of lung injury was significantly reduced,and the pathological score of lung injury and the ratio of Wwet/Ddry weight were decreased(P<0.05)when compared with the HALI group.Compared with the control group,the contents of MDA,Fe2+and ROS were increased(P<0.05),the activity of SOD and content of GSH were declined(P<0.05),the protein levels of STAT3 and P53 were increased(P<0.05),and those of SLC7A11 and GPX4 were decreased(P<0.05)in the HALI group.Compared with the HALI group,decreased MDA and ROS levels(P<0.05),enhanced SOD activity,Fe2+and GSH levels(P<0.05),down-regulation of STAT3 and P53(P<0.05)and up-regulation of SLC7A11 and GPX4(P<0.05)were observed in the miR-21 group and HY-13818 group.Conclusion MiR-21 alleviates HALI,which may be related to its inhibition of ferroptosis through the STAT3/P53/SLC7A11 axis.

Cardiac fibrosis is characterized by an elevated amount of extracellular matrix (ECM) within the heart. However, the persistence of cardiac fibrosis ultimately diminishes contractility and precipitates cardiac dysfunction. Circular RNAs (circRNAs) are emerging as important regulators of cardiac fibrosis. Here, we elucidate the functional role of a specific circular RNA CELF1 in cardiac fibrosis and delineate a novel feedback loop mechanism. Functionally, circ-CELF1 was involved in enhancing fibrosis-related markers' expression and promoting the proliferation of cardiac fibroblasts (CFs), thereby exacerbating cardiac fibrosis. Mechanistically, circ-CELF1 reduced the ubiquitination-degradation rate of BRPF3, leading to an elevation of BRPF3 protein levels. Additionally, BRPF3 acted as a modular scaffold for the recruitment of histone acetyltransferase KAT7 to facilitate the induction of H3K14 acetylation within the promoters of the Celf1 gene. Thus, the transcription of Celf1 was dramatically activated, thereby inhibiting the subsequent response of their downstream target gene Smad7 expression to promote cardiac fibrosis. Moreover, Celf1 further promoted Celf1 pre-mRNA transcription and back-splicing, thereby establishing a feedback loop for circ-CELF1 production. Consequently, a novel feedback loop involving CELF1/circ-CELF1/BRPF3/KAT7 was established, suggesting that circ-CELF1 may serve as a potential novel therapeutic target for cardiac fibrosis.
