ObjectiveTo analyze the research hotspots and development trends in the field of spinal cord stimulation (SCS) for spinal cord injury (SCI). MethodsLiterature about SCS for SCI was retrieve from the Web of Science (WOS) Core Collection database, with a time range from January, 1999 to July, 2025. VOSviewer 1.6.20 and CiteSpace 6.4.R2 were used to analyze the annual publication volume, countries, authors, institutions, journals and keywords. ResultsA total of 636 literatures were included. From 1999 to 2025, the overall publication trend in this field showed an upward trajectory, with recent years fluctuating but tending to stabilize. The country with the most publications was the United States (429 papers), followed by Russia (98 papers) and China (70 papers). The institution with the highest number of publications was the University of California, Los Angeles (76 papers), the author with the most publications was V. Reggie Edgerton (70 papers), and the journal with the most publications was Journal of Clinical Medicine (31 papers). The most frequently cited study focused on exploring the combination of epidural spinal cord stimulation with task-specific training to restore motor function in patients with complete SCI. Keyword analysis showed that the research hotspots in this field were mainly focused on neuroregulation mechanisms, recovery of motor and autonomic nervous dysfunction, artificial intelligence, closed-loop stimulation and brain-computer interface technology innovations. In recent years, the research focus gradually shifted from basic mechanisms to personalized and precise multifunctional rehabilitation strategies. ConclusionThe field of SCS for SCI has undergone phases of basic mechanism exploration and clinical application expansion. Current research hotspots and future trends focus primarily on the development of new stimulation paradigms and combined innovative technologies.

Sangjuyin， as a pungent and cooling agent with precise therapeutic effect， is a classic pungent formula for cooling relief of the epidermis， which is highly respected by medical practitioners. This formula is from the Wenbing Tiaobian written by WU Jutong in the Qing dynasty， on the basis of which subsequent medical practitioners have made additions and subtractions to apply it. The authors used the bibliometric method to systematically organize the medical books from the Qing dynasty and the Republic of China and modern literature to analyze the composition， concoction， decoction， efficacy， and previous and modern application of Sangjuyin. After examination， the drug base of this formula is basically clear. Armeniacae Semen Amarum is the dried mature seeds of Armeniaca vulgaris， family Rosaceae. Forsythiae Fructus is the dried fruit of Forsythia suspensa， family Mulleinaceae. Menthae Haplocalycis Herba is the dried above-ground part of Mentha haplocalyx， family Labiatae. Mori Folium is the dried leaves of Morus alba， family Moraceae. Chrysanthemi Flos is the dried head of Chrysanthemum morifolium， family Asteraceae. Platycodonis Radix is the dried root of Eryngium grandiflorum， family Eryngium. Glycyrrhizae Radix et Rhizoma is the dried root and rhizome of Glycyrrhiza uralensis of the Leguminosae family， and Phragmitis Rhizoma is the fresh or dried rhizome of Phragmites communis of the Gramineae family. It is recommended that the eight drugs be used in raw form as medicine. The dosage and method of decoction were converted into a modern single dosage of 7.46 g Armeniacae Semen Amarum， 5.60 g Forsythiae Fructus， 2.98 g Menthae Haplocalycis Herba， 9.33 g Mori Folium， 3.73 g Chrysanthemi Flos， 7.46 g Platycodonis Radix， 2.98 g Glycyrrhizae Radix et Rhizoma， and 11.19 g Phragmitis Rhizoma， with 400 mL water added， and the solution was boiled to obtain 200 mL， taken twice a day. Sangjuyin has the efficacy of dispersing wind and clearing heat， promoting lung and relieving cough， and it is used for treating the initial onset of wind-warmth and the evidence of evil spirits in the lungs and collaterals. Modern research has shown that Sangjuyin is often used in the treatment of cough， pneumonia， rhinitis， and other respiratory diseases， and the results of this study provide a reference for the later development of Sangjuyin.

Background Bufei Huoxue Capsule (BHC) has gradually been used in clinical practice to treat patients with pneumoconiosis in recent years. However, the comprehensive evaluation of its efficacy and safety is lacking. Objective To systematically assess the therapeutic potential of BHC for pneumoconiosis. Methods By searching 9 databases, e.g. China National Knowledge Infrastructure, Wanfang Database, VIP Chinese Science and Technology Journals Database, SinoMed, Yiigle, PubMed, Embase, Cochrane Library, and Web of Science, randomized controlled trials (RCTs) related to the use of BHC for the treatment of pneumoconiosis were identified. The search covered the period from the inception of these databases to August 31, 2025. This systematic review conformed to the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) 2020. The included studies underwent quality appraisal by the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE). Subgroup analysis and sensitivity analysis were applied to assess the robustness of results and explore the potential heterogeneity among the studies. Results A total of 19 RCTs were included and all were reported in Chinese. The therapy containing BHC showed a superior impact on forced expiratory volume in one second (FEV₁) (95%CI: 0.38, 0.66; I²=69%, P<0.05), FEV₁% (95%CI: 3.37, 5.72; I²=12%, P<0.05), forced vital capacity (FVC) (95%CI: 0.34, 0.45; I²=0%, P<0.05), FEV₁/FVC% (95%CI: 6.29, 10.35; I²=21%, P<0.05), 6-minute walking distance (6MWD) score (95%CI: 16.32, 27.64; I²=22%, P<0.05), St. George's Respiratory Questionnaire (SGRQ) score (95%CI: −1.47, −1.05; I²=13%, P<0.05), and total effective rate (95%CI: 2.71, 6.78; I²=0%, P<0.05) in patients with pneumoconiosis. In addition, BHC had less adverse reactions reported (95%CI: 0.69, 1.74; I²=0%, P=0.70). Conclusions Combined BHC therapy can significantly improve the lung function and the quality of life in patients with pneumoconiosis, with a good safety profile. However, high-quality RCTs with multicenter, large-sample, double-blind, and standardized protocols still need to be conducted in the future to provide more reliable evidence.

BACKGROUND:Cervical disc herniation can cause pain in the neck and shoulder area,as well as radiating pain in the upper limbs.The incidence rate is increasing year by year and tends to affect younger individuals.Fully understanding the biomechanical characteristics of the cervical spine in adolescents is of great significance for preventing and delaying the onset of cervical disc herniation in this age group. OBJECTIVE:To reconstruct cervical spine models for both healthy adolescents and adolescent patients with cervical disc herniation utilizing finite element analysis techniques,to analyze the motion range of the C1-T1 cervical vertebrae as well as the biomechanical characteristics of the annulus fibrosus,nucleus pulposus,endplates,and the cartilage of the small joints. METHODS:A normal adolescent's cervical spine and an adolescent patient with cervical disc herniation were selected in this study.The continuous scan cervical spine CT raw image data were imported into Mimics 21.0 in DICOM format.The C1-T1 vertebrae were reconstructed separately.Subsequently,the established models were imported into the 3-Matic software for disc reconstruction.The perfected models were then imported into Hypermesh software for meshing of the vertebrae,nucleus pulposus,annulus fibrosus,and ligaments,creating valid geometric models.After assigning material properties,the final models were imported into ABAQUS software to observe the joint motion range of the C1-C7 cervical vertebrae segments under different conditions,and to analyze the biomechanical characteristics of the annulus fibrosus,nucleus pulposus,endplates,and small joint cartilage of each cervical spine segment. RESULTS AND CONCLUSION:(1)In six different conditions,the joint motion range of the C1 vertebra in the cervical spine models of both normal adolescent and adolescent patient with cervical disc herniation was higher than that of the other vertebrae.Additionally,the joint motion range of each cervical spine segment in normal adolescent was greater than that in adolescent patient with cervical disc herniation.(2)In the cervical spine model of normal adolescent,the maximum stress values in the annulus fibrosus and nucleus pulposus were found on the left side during C2-3 flexion conditions(0.43 MPa and 0.17 MPa,respectively).In the cervical spine model of adolescent patient with cervical disc herniation,the maximum stress values were found on the left side during C7-T1 flexion conditions(0.54 MPa and 0.18 MPa,respectively).(3)In the cervical spine model of normal adolescent,the maximum stress value on the endplate was found on the left side of the upper endplate of C3 during flexion conditions(1.46 MPa).In the model of adolescent patient with cervical disc herniation,the maximum stress value on the endplate was found on the left side of the lower endplate of C7 during flexion conditions(1.32 MPa).(4)In the cervical spine model of normal adolescent,the maximum stress value in the small joint cartilage was found in the C2-3 left rotation conditions(0.98 MPa).In adolescent patient with cervical disc herniation,the stress in the small joint cartilage significantly increased under different conditions,especially in C1-2,with the maximum stress found during left flexion(3.50 MPa).(5)It is concluded that compared to normal adolescent,adolescent patient with cervical disc herniation exhibits altered cervical curvature and a decrease in overall joint motion range in the cervical spine.In adolescent with cervical disc herniation,there is a significant increase in stress on the annulus fibrosus,nucleus pulposus,and endplates in the C7-T1 segment.The stress on the left articular cartilage of the C1-2 is notable.Abnormal cervical curvature may be the primary factor causing these stress changes.

Objective:To explore the guiding significance of Expanded Carrier Screening (ECS) for the fertility process of individuals undergoing Assisted Reproductive Technology (ART) in Dalian.Methods:A retrospective analysis was conducted on the ECS results of patients who visited the Dalian Maternal and Child Health Care Center (Group) from January 2023 to June 2024. The study included the screening of 155 monogenic diseases and the ART status of carrier couples.Results:Among the 1 384 patient samples, 490 carriers were identified, yielding a detection rate of 35.41% (490/1 384). A total of 100 diseases and 91 pathogenic genes were detected. The most frequently identified disease was autosomal recessive hearing loss type 4 (SLC26A4), with a carrier rate of 3.54% (49/1384). For the 490 carriers, their partners were recalled for testing and, 322 partners participated. Eight high-risk couples were identified, accounting for 2.48% (8/322). Among the 322 couples, 4 used artificial insemination by husband (AIH, 1.24%, 4/322), 166 used in vitro fertilization (IVF, 51.55%, 166/322), 139 used intracytoplasmic sperm injection (ICSI, 43.17%, 139/322), and 1 underwent preimplantation genetic testing for monogenic diseases (PGT-M, 0.31%, 1/322). Twelve couples (3.73%, 12/322) did not undergo ART, were not pregnant, or chose gamete donation. Among the eight high-risk couples, three underwent IVF, four underwent ICSI, and one underwent PGT-M. One couple conceived through ICSI, and the fetus was followed up. Amniotic fluid Sanger sequencing revealed that the fetus had compound heterozygous mutations in the PAH gene, with two suspected pathogenic variants at c.532G>A and c.1174T>A. One couple undergoing PGT-M currently has one retrieved oocyte and zero usable blastocysts. The embryo carries a paternal mutation and is aneuploid.Conclusions:This study not only identified the common pathogenic diseases in Dalian, providing a reference for clinical treatment, but also validated the critical significance of ECS for individuals undergoing ART.

Objective:To investigate the diagnosis，therapeutic strategy and early prognosis of Scimitar syndrome in pediatric patients.Methods:Clinical data of 21 children with Scimitar syndrome admitted to the Department of Cardiothoracic Surgery of Shanghai Children's Medical Center from January 2014 to December 2021 were retrospectively analyzed，and divided into 11 cases in the infantile-type group and 10 cases in the adult-type group.Results:Twenty-one children with Scimitar syndrome，10 males and 11 females，aged 5 days to 10 years old. Compared with the adult-type group，the infant-type group had a high proportion of preoperative clinical symptoms( P<0.05)，a high concomitant rate of intracardiac malformations (100% vs. 40%， P=0.002)，a big size of aortopulmonary collateral(APC)[(0.77±0.25) mm/kg vs.(0.36±0.13) mm/kg， P=0.016]，a high incidence of pulmonary hypertension(91.0% vs. 50.0%， P=0.038), and a high proportion of severe pulmonary hypertension(50 % vs. 0). There was a high rate of postoperative complications of low cardiac output syndrome (36.4% vs. 0， P=0.034)，prolonged postoperative mechanical ventilation [(73.22±44.75) h vs. (19.5±12.79) h， P=0.007]，and prolonged length of ICU stay[(7.89±3.37) d vs. (2.50±1.26) d， P<0.001]. Eleven cases underwent surgical treatment only，and 10 cases received hybrid operation with APC occlusion. The survival rate of the whole group was 90.5%，and there was no case of pulmonary venous obstruction in the early postoperative period. Systolic pulmonary artery pressure/systolic artery pressure decreased significantly after surgery in 15 children with pulmonary arterial hypertension( P<0.01).Five cases in the infantile-type group still had pulmonary hypertension. Conclusion:Surgical effect of Scimitar syndrome in pediatric patients is satisfactory. Infants with Scimitar syndrome usually have more severe symptoms, higher incidence of severe pulmonary hypertension and relatively longer postoperative recovery time.

Objective To explore the mechanism of malt alcohol extract improving depression-like behavior induced by CUMS in rats by regulating gut microbiota.Methods The depression model of rats was established using an 8-weeks CUMS procedure,and the administration group was given low(59.6 mg·kg-1)and high(178.8 mg·kg-1)doses of malt alcohol extract,respectively.The depression-like behavior of rats was evaluated by classic behavioral test.The composition of intestinal microbiota of rats was analyzed by 16S rRNA sequencing.The morphological changes of colon were observed by hematoxylin and eosin(HE),the expression of ZO-1 and Occludin in colon was detected by immunofluorescence(IF),and the expression of IL-10,IL-1βand 5-HT were detected by ELISA.Results The low dose of malt alcohol extract attenuated the depressive behavior and restored the expression of 5-HT in the brain of CUMS rats.16S rRNA sequencing results showed that the diversity and relative abundance of gut microbiota changed after treatment with the low dose of malt alcohol extract.ELISA results showed that the low dose of malt alcohol extract significantly reversed the CUMS-induced reduction of IL-10 and elevation of IL-1 β.HE results showed that the low dose of malt alcohol extract significantly ameliorated CUMS-induced structural damage in colon.IF results showed increased protain expression of intestinal epithelial barrier tight junction proteins ZO-1 and Occludin by the low dose of malt alcohol extract.Conclusion The low dose of malt alcohol extract can ameliorate CUMS-induced depressive-like behavior in rats by modulating intestinal flora,restoring 5-HT expression in the brain,inhibiting inflammation,and repairing the intestinal barrier.

Objective:To investigate the extent and characteristics of parenting stress experienced by fathers of children aged 0-6 in three provinces of Eastern China, and to compare the quality of their marital relationships within each latent class, in order to provide reference for developing intervention strategies for different categories of fathers.Methods:Using cross-sectional survey methods, fathers with children aged 0-6 years were recruited using convenience sampling from December 2020 to March 2021 from Anhui province, Zhejiang province and Jiangsu province in Eastern China. Data were collected through a general information questionnaire, the Parenting Stress Index-Short Form, and the Locke-Wallace Marital Adjustment Scale.Latent profile analysis was used to determine the classification, Kruskal-Wallis H test was used to compare the difference of marital quality. Results:A total of 657 questionnaires were distributed and 604 valid questionnaires were recovered. The age of 604 fathers was (32.50 ± 6.26) years, the score of parenting stress was (89.70 ± 17.87) and the score of marriage quality was (108.36 ± 22.28). The characteristics of parenting stress among fathers of young children were categorized into three latent profile types: "high stress-negative parenting group" (88 people accounting for 14.6%), " medium stress- poor interaction group" (329 people accounting for 54.5%), and " low stress-positive parenting group" (187 people accounting for 30.9%). The scores of marriage quality were (99.94 ± 23.81), (106.52 ± 19.84), (115.56 ± 23.70) points among these three latent classes with significant differences ( H=35.89, P<0.05). Conclusions:The study identifies three latent classes of parenting stress among fathers of children aged 0-6, each associated with varying levels of marriage quality. Therefore, targeted interventions aimed at improving fathers′ parenting stress and marriage quality, and helping create family environments where children can grow up healthy.

Objective To analyze the epidemiological characteristics of acute respiratory infections(ARIs)during the autumn-winter season in Beijing,providing evidence for the prevention,control,diagnosis,and treatment of ARIs.Methods A convenience sampling method was employed,enrolling patients who visited Peking Union Medical College Hospital(PUMCH)between September 2023 and February 2024 due to ARIs.Na-sopharyngeal swabs were collected,and real-time fluorescence quantitative PCR was used to detect six common respiratory pathogens[influenza A virus(FluA),influenza B virus(FluB),human rhinovirus(HRV),Myco-plasma pneumoniae(MP),respiratory syncytial virus(RSV),and adenovirus(ADV)],as well as SARS-CoV-2 infection.The distribution patterns of pathogen infections were analyzed.Results A total of 5556 eligible patients were included.The overall positivity rate for the six common respiratory pathogens was 63.7％,with sin-gle-pathogen positivity at 54.0％,dual-pathogen positivity at 8.9％,and triple or more pathogen positivity at 0.7％.The predominant pathogens detected were FluA(16.1％)and RSV(15.7％),followed by ADV(11.1％),MP(11.1％),HRV(10.0％),and FluB(10.0％).No significant difference in overall pathogen positivity was observed between genders.However,significant differences were found between autumn and winter(x2=34.617,P＜0.001)and among pediatric,young/middle-aged,and elderly patients(x2=422.38,P＜0.001).Specifically,MP(x2=8.647,P=0.003),FluA(x2=131.932,P＜0.001),and HRV(x2=174.199,P＜0.001)exhibited significantly higher positivity rates in autumn than in winter,whereas FluB was more prevalent in winter(x2=287.894,P＜0.001).In pediatric patients,MP,RSV,HRV,and ADV positivity rates were significantly higher than in young/middle-aged and elderly patients(all P＜0.001),whereas FluB was more common in young/middle-aged patients(both P＜0.001).The positivity rates of the six common respiratory pathogens significantly declined during the SARS-CoV-2 epidemic period,exhibiting an asynchronous seasonal pattern.Conclusions The prevalence of respiratory pathogens in Beijing is associated with age and season.Tar-geted preventive measures should be implemented in different seasons and for key populations.

Objective To explore the value of 18F-flortaucipir tau PET combined with APOE ε4 genotype status for diagnosing mild cognitive impairment(MCI).Methods A total of 213 MCI patients(MCI group)and 402 healthy controls(HC group)were selected from Alzheimer's disease neuroimaging initiative(ADNI)database.The neuropsychological information,APOE ε4 gene carrier status,tau PET and high-resolution structural MRI data were recorded.The random forest algorithm was used to screen the most informative brain regions of tau PET for diagnosing MCI,and the efficacy of tau PET for distinguishing MCI with or without APOE ε4 gene and HC were compared.Results Amygdala,parahippocampal gyrus,entorhinal cortex,posterior cingulate gyrus,inferior temporal gyrus,fusiform gyrus and middle temporal gyrus in turn were the important brain regions of tau PET for diagnosing MCI.The accuracy and the area under the curve(AUC)of tau PET standardized uptake value ratio(SUVR)model for identifying MCI with APOE ε4 gene and HC was 86.68％and 0.784,respectively,both higher than those for identifying MCI and HC,as well as MCI without APOE e4 gene and HC(with accuracy of 70.57％and 75.05％,and AUC of 0.711 and 0.609).Conclusion 18F-flortaucipir tau PET SUVR model established based on amygdala,parahippocampal gyrus,entorhinal cortex,posterior cingulate gyrus,inferior temporal gyrus,fusiform gyrus and middle temporal gyrus could be used to diagnosing MCI.Combining with APOE ε4 gene could further improve its efficacy.
