Objective To investigate the clinical effects of different right lung volume reduction techniques when the donor lung is oversized and mismatched with the recipient. Methods Clinical data of 10 recipients who underwent right lung volume reduction lung transplantation at the First Affiliated Hospital of Xi'an Jiaotong University from October 2022 to June 2024 were collected, including gender, age, primary disease type, and type of transplantation. A retrospective analysis was performed on postoperative complications within 90 days, duration of mechanical ventilation, hospital stay, and survival status to explore the impact of different volume reduction techniques on the survival rate of lung transplant recipients. Results A total of 10 right lung volume reduction recipients were included in this study, with 2 cases of upper lobe reduction, 7 cases of middle lobe reduction, and 1 case of lower lobe reduction. Three recipients developed airway complications (one each with upper, middle, and lower lobe reduction). The 30-day survival rate was 90% and the 1-year survival rate was 70%. One recipient with upper lobe reduction died of septic shock during the perioperative period, one with lower lobe reduction died of airway anastomotic fistula 2 months after surgery, and one with middle lobe reduction died of renal insufficiency 1 year after surgery. All 7 recipients with middle lobe reduction successfully passed the perioperative period, with one case of airway anastomotic stenosis (1/7). The average duration of mechanical ventilation was 71 hours, and the average hospital stay was 26 days. The 30-day survival rate was 7/7, and the 1-year survival rate was 6/7. Conclusions Middle lobe reduction in right lung transplantation surgery has the advantages of low incidence of airway complications, good safety, and minimal loss of lung function, and may be a better right lung volume reduction option with potential for application.

Early identification of adolescent depression requires objective biomarkers. This study investigated the functional near-infrared spectroscopy (fNIRS) activation patterns and mismatch negativity (MMN) characteristics in adolescents with first-episode mild-to-moderate depression. We enrolled 33 patients and 33 matched healthy controls, measuring oxyhemoglobin (Oxy-Hb) concentration in the frontal cortex during verbal fluency tasks via fNIRS, and recording MMN latency/amplitude at Fz/Cz electrodes using event-related potentials (ERP). Compared with healthy controls, the depression group showed significantly prolonged MMN latency [Fz: (227.88 ± 31.08) ms vs. (208.70 ± 25.35) ms, P < 0.01; Cz: (223.73 ± 29.03) ms vs. (204.18 ± 22.43) ms, P < 0.01], and obviously reduced Fz amplitude [(2.42 ± 2.18) μV vs. (5.65 ± 5.59) μV, P = 0.03]. A significant positive correlation was observed between MMN latencies at Fz and Cz electrodes ( P < 0.01). Oxy-Hb in left frontopolar prefrontal channels (CH15/17) was significantly decreased in patient group ( P < 0.05). Our findings suggest that adolescents with depression exhibit hypofunction in the left prefrontal cortex and impaired automatic sensory processing. The combined application of fNIRS and ERP techniques may provide an objective basis for early clinical identification.

In order to further promote the standardization of the integrated traditional Chinese and western medicine treatment of atopic dermatitis(AD),the team of Professor Chen Dacan,who is honored as the Qihuang Scholar,developed the Clinical Practice Guidelines for Integrated Traditional Chinese and Western Medicine in Atopic Dermatitis(hereinafter referred to as Guidelines for AD).This paper detailed the process of development of Guidelines for AD,and analyzed the characteristics of Guidelines for AD,as well as the difficulties and countermeasures encountered during such a time.The development of Guidelines for AD follows the methodology of international guidelines for clinical trial.Experts specializing in various disciplines,such as traditional Chinese medicine,western medicine,integrated traditional Chinese and western medicine,and methodology,composed an expert group and a working group.On the basis of systematic literature research,the clinic experiences of frontline experts were well-summarized,and the draft of Guidelines for AD was formed after several meetings and discussions.In the process of developing Guidelines for AD,quite a number of problems were encountered,and the project team found the corresponding countermeasures after analyzing these problems.The countermeasures became the characteristics of Guidelines for AD:the integration of traditional Chinese medicine therapies and western medicine therapies,and the evaluation of the evidence of integrated traditional Chinese and western medicine solved the problem of traditional Chinese and western medicine diagnosis and treatment of AD lacking standardization;the adequately combination of the evidence with the experience of clinical practice solved the problems of the low overall level and the insufficiency of traditional Chinese medicine evidence for AD;the establishment of management goals and strategies for AD after taking the advantages of both traditional Chinese medicine and western medicine into account was in line with the international treatment and management concepts;the formulation of individualized traditional Chinese and western medicine therapy based on the integration of traditional Chinese medicine therapy and western medicine therapy met the clinical needs of patients with different characteristics of AD.The development process of Guidelines for AD and the analysis of problems and countermeasures during such a time will provide reference and reflection for the subsequent establishment of clinical guidelines for the integrated traditional Chinese and western medicine in other diseases.

BACKGROUND:Osteosarcoma has a complex pathogenesis and a poor prognosis.While advancements in medical technology have led to some improvements in the 5-year survival rate,substantial progress in its treatment has not yet been achieved. OBJECTIVE:To screen key molecular markers in osteosarcoma,analyze their relationship with osteosarcoma treatment drugs,and explore the potential disease mechanisms of osteosarcoma at the molecular level. METHODS:GSE99671 and GSE284259(miRNA)datasets were obtained from the Gene Expression Omnibus database.Differential gene expression analysis and Weighted Gene Co-expression Network Analysis(WGCNA)on GSE99671 were performed.Functional enrichment analysis was conducted using Gene Ontology and Kyoto Encyclopedia of Genes and Genomes separately for the differentially expressed genes and the module genes with the highest positive correlation to the disease.The intersection of these module genes and differentially expressed genes was taken as key genes.A Protein-Protein Interaction network was constructed,and correlation analysis on the key genes was performed using CytoScape software,and hub genes were identified.Hub genes were externally validated using the GSE28425 dataset and text validation was conducted.The drug sensitivity of hub genes was analyzed using the CellMiner database,with a threshold of absolute value of correlation coefficient|R|>0.3 and P<0.05. RESULTS AND CONCLUSION:(1)Differential gene expression analysis identified 529 differentially expressed genes,comprising 177 upregulated and 352 downregulated genes.WGCNA analysis yielded a total of 592 genes with the highest correlation to osteosarcoma.(2)Gene Ontology enrichment results indicated that the development of osteosarcoma may be associated with extracellular matrix,bone cell differentiation and development,human immune regulation,and collagen synthesis and degradation.Kyoto Encyclopedia of Genes and Genomes enrichment results showed the involvement of pathways such as PI3K-Akt signaling pathway,focal adhesion signaling pathway,and immune response in the onset of osteosarcoma.(3)The intersection analysis revealed a total of 59 key genes.Through Protein-Protein Interaction network analysis,8 hub genes were selected,which were LUM,PLOD1,PLOD2,MMP14,COL11A1,THBS2,LEPRE1,and TGFB1,all of which were upregulated.(4)External validation revealed significantly downregulated miRNAs that regulate the hub genes,with hsa-miR-144-3p and hsa-miR-150-5p showing the most significant downregulation.Text validation results demonstrated that the expression of hub genes was consistent with previous research.(5)Drug sensitivity analysis indicated a negative correlation between the activity of methotrexate,6-mercaptopurine,and pazopanib with the mRNA expression of PLOD1,PLOD2,and MMP14.Moreover,zoledronic acid and lapatinib showed a positive correlation with the mRNA expression of PLOD1,LUM,MMP14,PLOD2,and TGFB1.This suggests that zoledronic acid and lapatinib may be potential therapeutic drugs for osteosarcoma,but further validation is required through additional basic experiments and clinical studies.

After continuous development and improvement, lung transplantation has become the preferred means to treat a variety of benign end-stage lung diseases. However, the field of lung transplantation still faces many challenges, including shortage of donor resources, preservation and maintenance of donor lungs, and postoperative complications. Lung tissue samples removed after lung transplantation are excellent clinical resources for the study of benign end-stage lung disease and perioperative complications of lung transplantation. However, at present, the collection, storage and utilization of tissue samples after lung transplantation are limited to a single study, and unified technical specifications have not been formed. Based on the construction plan of the biobank for lung transplantation in the First Affiliated Hospital of Xi'an Jiaotong University, this study reviewed the practical experience in the collection, storage and utilization of lung transplant tissue samples in the aspects of ethical review, staffing, collection process, storage method, quality control and efficient utilization, in order to provide references for lung transplant related research.

Atopic dermatitis （AD） is a common pruritic and chronic inflammatory dermatosis in clinical practice and is one of the diseases responding specifically to traditional Chinese medicine （TCM）. With the launch of biological agents and small molecule drugs and the development and implementation of guidelines of diagnosis and treatment， clinical pathways of treatment of moderate to severe AD， and consensus on the whole-process management of AD， the clinical efficacy of moderate to severe AD has been significantly improved. However， there are still many unmet clinical needs that require more effective methods to meet. In response to the Opinions of the CPC Central Committee and the State Council on Facilitating the Inheritance， Innovation， and Development of Traditional Chinese Medicine and the spirit of the National Conference on TCM， the China Association of Chinese Medicine organized more than 20 experts in TCM dermatology， Western medicine dermatology， interdisciplinary fields， and industries to discuss the difficulties and advantages of TCM in the treatment of AD. TCM treatment for AD can not only improve rash and relieve itching but also solve many concomitant syndromes. The abundant external treatment methods of TCM have advantages for different special populations and rash characteristics. The concept of treating disease before its onset in TCM is in line with the chronic disease management mode of prevention and treatment of atopic march and prevention of recurrence. In addition， TCM therapy can reduce the use of topical glucocorticoids and has good safety. Regarding the comorbidity of AD， equal emphasis on TCM and Western medicine and multidisciplinary joint treatment should be advocated to achieve maximum benefit for patients. The exchange of TCM and Western medicine has clarified the positioning and advantages of TCM intervention in AD， providing guidance for clinical and scientific research.

The rationale for the design of control groups in tuina clinical trial is the foundation for rigorously validating the effectiveness and safety of this therapy. This article reviewed the current state of the design of tuina placebo in control groups of clinical trials， pointed out the necessity of setting up tuina placebo in clinical trials of tuina， analyzed the challenges in implementing blinding of tuina manipulation， and concluded that tuina placebo is still challenged by the placebo effect， the diversification of tuina manipulation but the lack of standardization， and the difficulty of implementing blinding due to the high level of public awareness of tuina. This article also summarized the design of placebo manipulation in three types of clinical trials， including spinal manipulation， acupressure， and paediatric tuina， and proposed four strategies for designing placebo tuina manipulation-controlling placebo effects， developing operational standards for placebo tuina manipulation， ensuring the rigor of blinding implementation， and applying new technologies to enhance the standardization and blinding capacity of placebo tuina methods. So the article is aimed at improving the methodological quality of tuina clinical trial designs， and promoting the standardization and scientificity of tuina clinical trial design.
