OBJECTIVE:To summarize the current status,hotspots,emerging trends,and frontiers of global research on the treatment of adolescent idiopathic scoliosis to provide reference and guidance for future related research. METHODS:The literature related to the treatment of adolescent idiopathic scoliosis was retrieved on the Web of Science Core Collection(WOSCC)database from 2013 to 2023.CiteSpace 6.2.R1 software was used for visual analysis of countries,institutions,authors,and keywords. RESULTS AND CONCLUSION:(1)A total of 561 English articles were included in this study.Among countries,institutions,and authors,the United States has contributed the most.Nanjing University and Qiu,Yong(Affiliated Drum Tower Hospital,Nanjing University School of Medicine)are the most published institution and author.The academic journal with the largest number of articles is the European Spine Journal.(2)In the analysis of cited literature,the top 10 most cited articles mainly describe the effects of surgical treatment and conservative treatment on improving adolescent idiopathic scoliosis,especially improving the curvature of patients.(3)Through the summary of highly cited articles and the keyword clustering,keyword prominence in-depth mining,the research hotspots are currently the relationship between Cobb angle and treatment choice,the therapeutic effect of exercise therapy and the therapeutic effect of posterior vertebral fusion.(4)The prognosis of patients with different curvatures has not been studied in depth,and the etiology of adolescent idiopathic scoliosis has not been clarified,so the relationship between curvature and prognosis and the etiology of adolescent idiopathic scoliosis may be a new research trend in the future.

Objective:To explore the real experience of parturients with pernicious placenta previa and placenta increta undergoing cesarean section from diagnosis to childbirth, so as to provide theoretical basis for clinical treatment and nursing decision-making.Methods:This study was a qualitative study. From November 2022 to January 2023, purposive sampling was used to select 13 parturients with pernicious placenta previa and placenta increta in the Department of Obstetrics of the First Affiliated Hospital of Zhengzhou University for semi-structured in-depth interviews. After collecting and organizing interview data, the Colaizzi 7-step analysis method was used to analyze the data, in order to understand the real experiences of parturients with pernicious placenta previa and placenta increta undergoing cesarean section.Results:The real experience of parturients with pernicious placenta previa and placenta increta undergoing cesarean section was extracted into three themes and 12 sub-themes. The first theme was the difficulties in seeking medical advice, with a complex and tortuous inner experience (the sub-themes include the unknown and fear in the early stages of diagnosis, the difficult struggle to make medical decisions, the arduous journey to protect the fetus, the physical and mental pain during the perioperative period, the joy of being born in a desperate situation, and concerns about the newborn and the new family pattern). The second theme was the personal positive coping experience during pregnancy and childbirth (the sub-themes include actively seeking disease information and professional support, quickly changing roles and completing role adaptation, evoking past experiences and reflecting resilient multipara traits). The third theme was to effectively utilize family social support (the sub-themes include trust and compliance with medical institutions to meet disease diagnosis and treatment needs, receiving professional guidance from medical and nursing staff to eliminate negative psychology and meet knowledge needs, benefiting from spouse and family support to meet life and emotional needs) .Conclusions:Parturients with pernicious placenta previa and placenta increta undergoing cesarean section can actively cope with the disease during pregnancy and childbirth, but still have negative emotions. Medical and nursing staff should promptly anticipate potential risks, provide correct information, professional guidance, and assistance to pregnant and postpartum women and their families, and eliminate their negative psychology among them.

Objective:To compare the postoperative recurrence rates between Thulium laser en bloc resection of bladder tumor (ERBT) and traditional transurethral resection of bladder tumor (TURBT) in treating patients with non-muscle invasive bladder cancer (NMIBC).Methods:A retrospective analysis was conducted on the clinical data of 1 439 patients with NMIBC who underwent either Thulium laser ERBT or TURBT in Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, between January 2010 and March 2024. Among them, 201 patients received Thulium laser ERBT, while 1 238 patients underwent TURBT. Propensity score matching (PSM) was employed in a 1∶1 ratio to eliminate selection bias due to non-random assignment, ensuring the comparability of clinical baseline data such as gender, age, pathological diagnosis, T stage, tumor grade, tumor size, and tumor number between the two groups. Kaplan-Meier method was used to generate recurrence-free survival curves for the matched groups, and the log-rank test was conducted to compare differences between the groups. Univariate and multivariate Cox regression analyses were performed to identify independent risk factors affecting postoperative recurrence.Results:After PSM matching, 193 patients were included in each group. There were no statistically significant differences between the two groups in terms of gender ( P=0.317), age ( P=0.207), pathological type ( P=0.756), T stage ( P=0.402), tumor grade ( P=0.965), tumor size ( P=0.821), or number of tumors ( P=0.421). The median follow-up time was 16.2(8.0, 33.9) months. Excluding patients with non-urothelial tumors such as adenocarcinoma and squamous cell carcinoma, there were 180 cases in the Thulium laser ERBT group and 184 cases in the TURBT group. Survival analysis showed that the postoperative recurrence rate of urothelial carcinoma patients in the Thulium laser ERBT group was lower than that in the TURBT group [20.0%(36/180) vs. 38.6%(71/184), P<0.001]. Stratified survival analysis indicated that in patients with tumor diameters ≤30 mm [22.3%(29/130) vs. 33.6%(45/134), P=0.017] or >30 mm [14.0%(7/50) vs. 52.0%(26/50), P=0.002], the Thulium laser ERBT group had lower postoperative recurrence rate compared to the TURBT group.Among patients with single tumor, the recurrence rate in the Thulium laser ERBT group was lower than in the TURBT group[10.5%(11/105) vs. 31.5%(35/111), P<0.001]. However, among patients with multiple tumors, there was no statistically significant difference in recurrence rates between the Thulium laser ERBT group and the TURBT group [35.7%(25/70) vs. 47.9%(34/71), P=0.061]. Univariate and multivariate Cox regression analyses indicated that Thulium laser ERBT treatment was an independent protective factor against postoperative recurrence in NMIBC patients ( HR=0.44, 95% CI 0.30-0.66, P<0.001). Patients with adenocarcinoma ( HR=5.85, 95% CI 2.07-16.51, P<0.001), squamous cell carcinoma ( HR=2.98, 95% CI 1.04-8.55, P=0.042), or other types of tumors ( HR=2.98, 95% CI 1.14-7.75, P=0.026) had higher risks of recurrence. High-grade tumor patients faced increased risks of postoperative recurrence ( HR=1.84, 95% CI 1.21-2.79, P=0.004). Additionally, tumors >30 mm had increased risks of postoperative recurrence compared to those ≤30 mm ( HR=2.00, 95% CI1.31-3.05, P=0.001). Patients with single tumor had significantly reduced risks of postoperative recurrence compared to those with multiple tumors ( HR=0.50, 95% CI 0.34-0.73, P<0.001). Conclusions:Regardless of tumor diameter (≤30 mm or >30 mm), Thulium laser ERBT significantly reduces the postoperative recurrence rate in patients with urothelial carcinoma compared to TURBT, with the advantage being more pronounced in patients with single bladder tumor. Additionally, patients with high-grade tumors, tumor diameters >30 mm, or multiple bladder tumors have higher risk of postoperative recurrence.

Objective:To analyze the types and functions of CD34 + cells in full-thickness skin defect wounds of normal mice and diabetic mice by single-cell RNA sequencing. Methods:This study was an experimental study. The CD34 + cell lineage tracing mouse was produced, and the visualization of CD34 + cells under the fluorescent condition was realized. Six male CD34 + cell lineage tracing mice aged 7-8 weeks (designated as diabetic group) were intraperitoneally injected with streptozotocin to establish a diabetic model, and full-thickness skin defect wounds were prepared on their backs when they reached 13 weeks old. Another 6 male CD34 + cell lineage tracing mice aged 13 weeks (designated as control group) were also subjected to full-thickness skin defect wounds on their backs. On post-injury day (PID) 4, wound tissue was collected from 3 mice in control group and 2 mice in diabetic group, and digested to prepare single-cell suspensions. CD34 + cells were screened using fluorescence-activated cell sorting, followed by single-cell RNA sequencing. The Seurat 4.0.2 program in the R programming language was utilized for dimensionality reduction, visualization, and cell clustering analysis of CD34 + cell types, and to screen and annotate the marker genes for each CD34 + cell subpopulation. Kyoto encyclopedia of genes and genomes (KEGG) and gene ontology (GO) enrichment analysis was performed to analyze the differentially expressed genes (DEGs) of CD34 + fibroblasts (Fbs), smooth muscle cells (SMCs), keratinocytes (KCs), and chondrocyte-like cells (CLCs) in the wound tissue of two groups of mice for exploring cellular functions. Results:On PID 4, CD34 + cells in the wound tissue of both groups of mice were consisted of 7 cell types, specifically endothelial cells, Fbs, KCs, macrophages, T cells, SMCs, and CLCs. Among these, Fbs were further classified into 5 subpopulations. Compared with those in control group, the proportions of CD34 + endothelial cells, Fbs subpopulation 1, Fbs subpopulation 4, KCs, and CLCs in the wound tissue of mice were increased in diabetic group, while the proportions of CD34 + Fbs subpopulation 2, Fbs subpopulation 3, and SMCs were decreased. The marker genes for annotating CD34 + CLCs, endothelial cells, Fbs subpopulation 1, Fbs subpopulation 2, Fbs subpopulation 3, Fbs subpopulation 4, Fbs subpopulation 5, KCs, macrophages, SMCs, and T cells were respectively metastasis-associated lung adenocarcinoma transcript 1, fatty acid binding protein 4, Gremlin 1, complement component 4B, H19 imprinted maternally expressed transcript, Dickkopf Wnt signaling pathway inhibitor 2, fibromodulin, keratin 5, CD74 molecule, regulator of G protein signaling 5, and inducible T-cell co-stimulator molecule. KEGG and GO enrichment analysis revealed that, compared with those in control group, DEGs with significant differential expression (SDE) in CD34 + Fbs from the wound tissue of mice in diabetic group on PID 4 were significantly enriched in terms related to inflammatory response, extracellular matrix (ECM) organization, regulation of cell proliferation, and aging (with Pvalues all <0.05), DEGs with SDE in CD34 + SMCs were significantly enriched in terms related to cell migration, apoptotic process, positive regulation of transcription, and phagosome (with P values all <0.05), DEGs with SDE in CD34 + KCs were significantly enriched in terms related to mitochondrial function, transcription, and neurodegenerative diseases (with P values all <0.05), and DEGs with SDE in CD34 + CLCs were significantly enriched in terms related to rhythm regulation, ECM, and viral infection (with P values all <0.05). Conclusions:CD34 + cells display high heterogeneity in the healing process of full-thickness skin defect wounds in both normal mice and diabetic mice. The significantly enriched functions of DEGs with SDE in CD34 + cell subpopulations in the wound tissue of the two mouse groups are closely related to the wound healing process.

Objectives:To determine the effect of glucose-6-phosphate-dehydrogenase (G6PD) deficiency on patients’ complications and prognosis following allogeneic stem cell hematopoietic transplantation (allo-HSCT) .Methods:7 patients with G6PD deficiency (study group) who underwent allo-HSCT at Peking University People's Hospital from March 2015 to January 2021 were selected as the study group, and thirty-five patients who underwent allo-HSCT during the same period but did not have G6PD deficiency were randomly selected as the control group in a 1∶5 ratio. Gender, age, underlying diseases, and donors were balanced between the two groups. Collect clinical data from two patient groups and perform a retrospective nested case-control study.Results:The study group consisted of six male patients and one female patient, with a median age of 37 (range, 2-45) years old. The underlying hematologic diseases included acute myeloid leukemia ( n=3), acute lymphocytic leukemia ( n=2), and severe aplastic anemia ( n=2). All 7 G6PD deficiency patients achieved engraftment of neutrophils within 28 days of allo-HSCT, while the engraftment rate of neutrophils was 94.5% in the control group. The median days of platelet engraftment were 21 (6–64) d and 14 (7–70) d ( P=0.113). The incidence rates of secondary poor graft function in the study group and control group were 42.9% (3/7) and 8.6% (3/35), respectively ( P=0.036). The CMV infection rates were 71.4% (5/7) and 31.4% (11/35), respectively ( P=0.049). The incidence rates of hemorrhagic cystitis were 57.1% (4/7) and 8.6% (3/35), respectively ( P=0.005), while the bacterial infection rates were 100% (7/7) and 77.1% (27/35), respectively ( P=0.070). The infection rates of EBV were 14.3% (1/7) and 14.3% (5/35), respectively ( P=1.000), while the incidence of fungal infection was 14.3% (1/7) and 25.7% (9/35), respectively ( P=0.497). The rates of post-transplant lymphoproliferative disease (PTLD) were 0% and 5.7%, respectively ( P=0.387) . Conclusions:The findings of this study indicate that blood disease patients with G6PD deficiency can tolerate conventional allo-HSCT pretreatment regimens, and granulocytes and platelets can be implanted successfully. However, after transplantation, patients should exercise caution to avoid viral infection, complications of hemorrhagic cystitis, and secondary poor graft function.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.

Objective:To explore the prognostic impact of different intracranial radiotherapy modalities in patients with a limited number (≤10) of brain metastases from small cell lung cancer (SCLC-BM).Methods:The data of 143 cases with SCLC-BM that received intracranial radiotherapy at the First Affiliated Hospital of Bengbu Medical University in 2019-2022 were analyzed. The patients were grouped by radiotherapy modalities: whole brain radiotherapy (WBRT, 58 cases), WBRT combined with simultaneous integrated boost (WBRT+ SIB, 53 cases), and WBRT combined with sequential integrated boost (WBRT+ SEB, 32 cases). The overall survival (OS) and intracranial progression-free survival (IPFS) were calculated using the Kaplan-Meier method, and the Cox proportional hazard model was used for prognostic analysis.Results:In the whole group, the median OS and IPFS were 11.9 and 9.9 months, and the 1-, 2-, and 3-year survival rates were 49.7%, 15.3%, and 2.9%, respectively. The difference in OS among patients in the WBRT+ SIB, WBRT+ SEB, and WBRT groups was not significant (median OS: 13.0 months vs. 12.5 months vs. 11.2 months, P>0.05). The WBRT+ SIB and WBRT+ SEB groups were preferred over the WBRT group in terms of IPFS (median IPFS: 11.7 months vs. 10.4 months vs. 8.1 months, χ2=21.69, P<0.001). For patients with few brain metastases (≤3) analyzed separately, the WBRT+ SIB and WBRT+ SEB groups were preferred over the WBRT group in terms of OS and IPFS (median OS: 14.4 months vs. 13.7 months vs. 11.5 months, χ2=8.72, P=0.013; median IPFS: 12.6 months vs. 10.4 months vs. 8.9 months, χ2=12.37, P=0.002). Evaluation of the central nervous system as well as hematological acute radiological reactions reaching grade 2 and above showed no significant differences among the three groups ( P>0.05). Multivariate analysis showed that subsequent chemotherapy, targeted therapy, and immunotherapy were common independent influencing factors for patients′ OS and IPFS. Body mass index (BMI) level was an independent influencing factor for patients′ OS, and the number of brain metastases, lymph node metastasis, and radiotherapy modality were independent influencing factors for patients′ IPFS. Conclusions:BMI level and subsequent treatment (chemotherapy, targeted therapy, and immunotherapy) are independent influencing factors for patients' prognosis. WBRT+ SIB and WBRT+ SEB modalities are associated with increased IPFS.

ObjectiveTo observe the clinical effectiveness of midnight-noon ebb-low acupuncture by hour-prescription of points combined with western medicine for patients of Parkinson's disease with restless legs syndrome. MethodsSixty cases of Parkinson's disease with restless legs syndrome were divided into a control group and a treatment group randomly， with 30 cases in each group. The control group was given conventional western medicine treatment， and the treatment group was given the treatment of the control group with midnight-noon ebb-low acupuncture by hour-prescription of points based on Daling （PC 7）， Zhongzhu （TE 3）， Yanglingquan （GB 34）， Zusanli （ST 36）， and Sanyinjiao （SP 6） with perpendicular insertion， and Baihui （GV 20） with oblique insertion to the back，all of them used the manipulation of neutral reinforcement and reduction； Dudu （SP 2） and Taibai （SP 3） acupoints were inserted in accordance with the direction of the meridian travelling when the patients inhaled， and the needle was removed when exhaled； the time of acupuncture manipulation selected as Si time （9 AM-11 AM）， the needle stay for 30 mins each time， once a day， 5 times a week， a total of 4 weeks of treatment. The international restless legs severity scale （IRLSS）， Pittsburgh sleep quality index （PSQI）， Parkinson's disease quality of life questionnaire （PDQ-39）， and the International Movement Disorder Society unified Parkinson's disease rating scale part Ⅰ （MDS-UPDRS Ⅰ） were compared before and after the treatment， and the clinical effectiveness of the two groups were compared after the treatment. ResultsIRLSS scores， PSQI scores， PDQ-39 scores and MDS-UPDRS Ⅰ scores decreased in both groups after treatment compared to those before treatment （P＜0.05 or P＜0.01）. After treatment， the total effective rate in the treatment group （83.3%， 25/30） was higher than that in the control group （60%， 18/30） （P＜0.05）. ConclusionAdding midnight-noon ebb-low acupuncture with hour-prescription of points on conventional western medicine treatment for Parkinson's disease with restless legs syndrome can significantly improve patients' clinical symptoms， sleep quality， quality of life， and enhance clinical effectiveness.

Metabolic associated fatty liver disease has become the most important chronic liver disease in China.Its mechanism is not completely clear.Professor Sheng Guoguang examines the symptoms and seek the cause,treats the disease by stages from the perspective of"earth-obstructing and wood-stagnation,phlegm and blood stasis",summarizes the core pathogenesis of each stage,and prescribes drugs for the pathogenesis.In the early stage,the disease is mainly caused by earth-obstructing and wood-stagnation and phlegm and blood stasis and the corresponding treatment method should be activating spleen to eliminate depression,relieving phlegm and promoting blood circulation,with common use of modified Sizhu Decoction combined with Erchen Decoction.In the middle stage,phlegm and blood stasis transform into heat are the main pathogenesis,and the appropriate treatment is clearing liver and purging fire,and relieving phlegm and promoting blood circulation,with common use of modified Xiaochaihu Decoction combined with Erchen Decoction.In the late stage,weakness of the internal organs is the main pathogenesis,and it is appropriate to nourish liver and fortify the spleen,tonifying the kidney and consolidate the root,supplementing with reducing phlegm and activating blood circulation,with common use of modified Yiguan Decoction combined with Liujunzi Decoction in modification,which has achieved confirmed clinical efficacy.

Objective To investigate the distribution and seasonal fluctuations of visceral leishmaniasis vectors sandflies in Lüliang City, Shanxi Province, so as to provide insights into assessment of the visceral leishmaniasis transmission risk and formulation of visceral leishmaniasis control measures. Methods A total of 12 natural villages were sampled from Shilou County, Lishi District, Lanxian County, Linxian County and Wenshui County in Lüliang City, Shanxi Province from June to September, 2023, and sandflies were captured using light traps from 7 breeding habitats, including farmers’ houses, sheep pens, cattle pens, chicken coops, pig pens, mule and horse pens, and loess-cave dwellings. Following morphological identification of the sandfly species, the distribution of sandflies and the seasonal fluctuations of the sandfly density were analyzed. In addition, the Leishmania was detected in sandflies using a real-time fluorescence quantitative PCR assay. Results A total of 2 831 sandflies were captured with 156 light traps in Lüliang City from June to September, 2023, including 2 638 female sandflies (93.18%) and 193 male sandflies (6.82%), and the average density was 16.91 sandflies/(light-night). The seasonal fluctuations of the sandfly density all appeared a unimodal distribution in all survey sites, and the sandfly density peaked in July and then declined rapidly. Among all types of breeding habitats, the greatest sandfly density was found in sheep pens [39.04 sandflies/(light-night)]. In addition, 4.08% (2/49) of the sandfly samples were tested positive for Leishmania nucleic acid as revealed by the real-time fluorescence quantitative PCR assay. Conclusions Sandflies were widely distributed in Lüliang City, Shanxi Province in 2023, and the peak of the sandfly density was observed in July, which had a visceral leishmaniasis transmission risk. Intensified surveillance of visceral leishmaniasis and sandfly vectors is required and targeted vector control is recommended.
