Psoriasis is a common chronic inflammatory systemic disease in dermatology. Its high prevalence， recurrence rate， and numerous comorbidities impose a significant physical and mental burden on patients. With the continuous advancement of modern medicine， the emergence of biological agents has improved clinical efficacy， making it possible to overcome psoriasis， in addition to classical treatments. However， in clinical practice， adverse reactions， drug resistance， recurrence rates， and immune drift cannot be ignored. Traditional Chinese medicine （TCM） has a history of thousands of years in treating psoriasis， demonstrating good efficacy， high safety， and a low recurrence rate， but a standardized management system is lacking. Therefore， the 25^th Clinical Diseases Responding Specially to TCM Treatment Series （Psoriasis） Youth Salon， hosted by the Chinese Association of Chinese Medicine and organized by the Youth Committee of the Chinese Association of Chinese Medicine， invited 29 experts and scholars from TCM， Western medicine， and interdisciplinary fields to actively discuss the "Advantages， Challenges， and Clinical Transformation of TCM and Western Medicine in the Diagnosis and Treatment of Psoriasis". The experts at the meeting concluded that the advantages of TCM in the treatment of psoriasis are as follows. Firstly， in the TCM-led treatment plan， TCM's understanding of psoriasis follows the principle of combining the differentiation of disease and syndrome. This approach distinguishes the basic contradiction from the current main contradiction and enables a clear grasp of the dynamic process of psoriasis development. Based on the system of syndrome differentiation and treatment， TCM intervention is applied to address the current main contradiction， and the optimal TCM treatment plan is formulated by combining internal and external treatments. Adhering to the principle of "what is visible outside must be addressed inside"， TCM can prevent and treat psoriasis comorbidities early by differentiating syndrome types. Secondly， in the integrated TCM and Western medicine treatment plan， the combination of both methods not only enhances efficacy but also reduces the adverse reactions of immunosuppressants and biological agents， lowering the recurrence rate. This conference provides a reference for the diagnosis and treatment of psoriasis using TCM and integrated TCM and Western medicine， opening up new ideas for clinical and basic research and guiding future research directions.

Objective To systematically evaluate the rehabilitation effect of immersive virtual reality technology for patients with peripheral vestibular dysfunction,and to provide theoretical basis and practical guidance for the design of efficient rehabilitation training programs.Methods PubMed,Embase,Cochrane Library,Web of Science,CINAHL,CNKI,Wanfang Database,VIP Database,and China Biomedical Literature Database were searched for randomized controlled trials on the intervention effect of immersive virtual reality technology in patients with peripheral vestibular dysfunction from inception to February 2025.RevMan5.4 software was used to perform meta-analysis of the literature that met the quality standards.Results A total of 10 papers with 491 patients with peripheral vestibular dysfunction were included.Meta-analysis showed that immersive virtual reality technology improved vertigo symptoms in patients with peripheral vestibular dysfunction compared with conventional vestibular rehabilitation care[SMD=-1.41,95％CI(-1.58,-0.70),P＜0.001],and subgroup analysis showed that the frequency of intervention was＜5 times/week[SMD=-1.31,95％CI=(-1.96,-0.66),P＜0.001],single intervention duration＜30 min[SMD=-1.45,95％CI=(-2.21,-0.70),P＜0.001],and intervention period≤7 weeks[SMD=-1.49,95％CI(-2.04,-0.94),P＜0.001]were more significant.Immersive virtual reality technology reduced the risk of falls[MD=4.66,95％CI(3.84,5.48),P＜0.001],and improved anxiety and depression[SMD=2.65,95％CI(1.98,3.33),P＜0.001].Conclusion Immer-sive virtual reality technology improves vertigo symptoms,reduces the risk of falls,and improves anxiety and depres-sion symptoms in patients with peripheral vestibular dysfunction,in which the intervention period of ≤7 weeks,＜5 training sessions per week,and each training session of＜30 min are better for improving vertigo symptoms in patients with peripheral vestibular dysfunction.

Objective:To assess the association of single nucleotide polymorphisms of rs700519 and rs4646 loci of cytochrome P450 19A1 ( CYP19A1) gene with risk of breast cancer. Methods:Two hundred patients with breast cancer treated at Xinxiang Central Hospital between January 2019 and January 2024 and 100 healthy individuals were enrolled as the study group and control group, respectively. The genotypes of the CYP19A1 gene at the rs700519 and rs4646 loci were determined by direct sequencing. The general data, distribution of CYP19A1 genotypes and alleles were compared between the two groups. This study has been approved by the Medical Ethics Committee of Xinxiang Central Hospital (Ethics No.2021-182). Results:No significant difference was found in age, body mass index, times of conception and proportion of menopause between the two groups ( P>0.05). The frequencies of AA genotype and A allele at the rs700519 locus, and the CC genotype and C allele at the rs4646 locus in the study group were significantly higher than those of the control group ( P<0.05). The frequencies of AA genotype at the rs700519 locus and CC genotype at the rs4646 locus in patients with breast cancer at stages Ⅲ-Ⅳ were significantly higher than those at stage Ⅰ-Ⅱ ( P<0.05). Conclusion:Polymorphisms of CYP19A1 gene at the rs700519 and rs4646 loci are associated with susceptibility of breast cancer. The AA and CC genotypes at the two loci may increase the risk for breast cancer.

The intestine and liver are closely connected both physiologically and pathologically, forming a so-called gut-liver axis, with the gut microbiota serving as a pivotal link in their bidirectional communication. Gut microbiota dysbiosis and gut-liver axis disruption play a key role in the development and progression of colorectal cancer liver metastasis (CRLM), though the underlying mechanisms have not been clearly elucidated. Certain gut microbiota, such as Escherichia coli and Enterococcus spp., can breach the intestinal barrier and translocate to the liver, promoting the formation of pre-metastatic niche. Fusobacterium nucleatum and Enterococcus faecalis enhance tumor cell invasion/migration, while Parabacteroides spp. suppress anti-tumor immunity in the liver TME. Interventions like fecal microbiota transplantation, dietary modifications, and traditional Chinese medicine have shown potential in clinical and preclinical studies to improve patient outcomes by targeting the gut microbiota, but their long-term efficacy and safety require further investigation. Future research should focus on elucidating the effects of specific bacterial species, metabolites, viruses, and fungi on tumorigenesis. Exploring the potential of gut microbiota-based precision medicine and personalized therapies will improve risk stratification and enable more targeted interventions for CRLM patients.

Objective:To investigate the epidemiological and clinical characteristics of patients with nontuberculous mycobacterial infections in Hunan Province using metagenomics next generation sequencing (mNGS) .Methods:Pathological data form 320 patients diagnosed with mycobacterial infections at the Department of Pathology of Hunan People′s Hospital from June 2019 to December 2023 were collected, including HE staining, acid-fast staring, and fungal fluorescence staining. mNGS was utilized for the classification of mycobacterial pathogens.Results:Among 320 patients with mycobacterial infections, 249 cases were positive for Mycobacterium tuberculosis and 71 cases were positive for nontuberculous mycobacteria. Thirteen genera of nontuberculous mycobacteria were identified from the mycobacterial samples, including Mycobacterium chelonae, Mycobacterium avium complex, Mycobacterium abscessus, Mycobacterium gordonae, Mycobacterium intracellulare, Mycobacterium xenopi, Mycobacterium kansasii, Mycobacterium paragordonae, Mycobacterium obuense, Mycobacterium marinum, Mycobacterium fortuitum, Mycobacterium smegmatis and Mycobacterium mageritense. Conclusions:Infections caused by nontuberculous mycobacteria are gradually increasing, transitioning from single-strain infections to multi-strain complex infections. The histopathological features of nontuberculous mycobacterial infections are difficult to distinguish form those of tuberculosis, posing significant challenges for clinical diagnosis and treatment.

Objective:To explore the clinical manifestation and genotype of a child with Progressive familial intrahepatic cholestasis 8 (PFIC8) due to variant of KIF12 gene. Methods:A child diangosed with PFIC8 at Changzhou Children′s Hospital in October 2017 was selected as the study subject. Clinical data of the child was collected. Peripheral blood samples (3 mL each) were collected from the patient, her parents and younger sister. Following extraction of genomic DNA, whole exome sequencing (WES) was carried out. Candidate variants were validated using Sanger sequencing. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the pathogenicity of candidate variants was classified. This study has been approved by the Medical Ethics Committee of Changzhou Children′s Hospital (Ethics No.: 2023-002).Results:The main clinical manifestations of the child included high GGT cholestasis, portal hypertension, splenomegaly, and abnormal liver enzymes. WES revealed that she has harbored compound heterozygous variants of the KIF12 gene, namely c. 245G >A (p.Arg82Gln) and c. 1291del (p.Ser431Valfs*13). Bioinformatics analyses showed that both variants were pathogenic. A total of 25 cases were reported in 7 English literature, including 13 males and 12 females. All patients had presented with high GGT cholestasis. Some had progressed to cirrhosis, and 3 cases also had renal lesions. No death was reported. Six children were treated with LTx. Nineteen children were found to harbor homozygous variants of the KIF12 gene, and the remaining six harbored compound heterozygous variants of the same gene. The most common mutation was c. 655C>T (p.Arg219*). The mutation sites are mainly located in the Kinesin motor catalytic domain, with high GGT cholestasis as the main clinical feature. No correlation was found between the genotype and phenotype. Conclusion:PFIC8 caused by KIF12 deficiency is mainly characterized by high GGT cholestasis, for which there is no effective treatment. The c. 245G>A and c. 1291del compound heterozygous variants of the KIF12 gene probably underlay the pathogenesis in this child.

With the advancement of space exploration missions,space station operations have entered a routine phase,where single-flight missions last up to six months.Previous studies indicate that the spaceflight environment severely compromises the immune system,increasing the susceptibility to diseases.As primary responders to pathogenic challenges,immune cells exhibit exceptional sensitivity to gravitational alterations and background ionizing radiation in space,with their dysfunction being a critical health risk.For innate immunity,the complex space environment disrupts macrophage polarization and phagocytosis,neutrophil chemotaxis and killing,natural killer(NK)cell cytotoxicity,and dendritic cell maturation,leading to functional impairment of innate immune defenses.For adaptive immunity,microgravity and radiation induce cellular immune dysregulation by suppressing T cell proliferative capacity and perturbing Th1/Th2/Treg subset balance,while simultaneously undermining humoral immunity through interference with B-lymphocyte protein synthesis,blockade of developmental maturation,and reduction of effector B cell populations.This review summarizes recent advances in understanding space environment-induced immune perturbations and protection options using traditional Chinese medicine,focusing on microgravity and radiation.It not only deciphers molecular mechanisms underpinning immune cell dysfunction but also provides a theoretical foundation and drug-targeting strategies for developing countermeasures against spaceflight-specific immune dysfunction.

Objective To investigate biological markers associated with psychotic symptoms in patients with bipolar disorder(BD)based on electronic medical records of patients,and to develop an interpretable risk prediction model that supports the identification of high-risk individuals and that facilitates decision-making for providing clinical intervention in a timely manner.Methods A total of 2 352 patients diagnosed with BD and admitted to West China Hospital,Sichuan University were enrolled using the electronic medical records system of the hospital.The participants were divided into two subgroups,the bipolar disorder depression(BDD)group and the bipolar disorder mania(BDM)group.The logistic regression algorithm was used to train and validate the prediction model,and interpretability methods were used to analyze the contribution of each feature to individuals and the effect of the features on specific target prediction decisions.Results The logistic regression model demonstrated robust predictive performance across the BD,BDD,and BDM cohorts,with areas under the curve(AUC)of the receiver operating characteristic curves always exceeding 81.6%.The core predictive features included platelet distribution width(PDW),fibrinogen(FIB),platelet large cell ratio(P-LCR),activated partial thromboplastin time(APTT),prothrombin time(PT),and triglyceride(TG).The logistic regression model exhibited strong interpretability and was combined with nomograms for intuitive risk quantification and individualized prediction.Conclusion The logistic regression model enables rapid and simple screening of BD patients with psychotic symptoms.Distinct patterns of changes observed in blood biomarkers of BDD and BDM subgroups enrich the understanding of the underlying pathophysiological mechanisms and highlight the importance of considering subtypes in the intervention and management of patients.

Objective To investigate the current situation of the attitude and practical ability of hospice care in the terti-ary cancer hospital of Zhejiang Province,so as to provide reference for managers to explore more effective hospice care support.Methods Using convenience sampling selected 278 clinical nurses from Zhejiang Cancer Hospital.From June to August 2024,the general data questionnaire,hospice care attitude scale and self-assessment practice scale of hospice care were used to survey nurses with questionnaires,and the related factors affecting practical ability and the correlation between attitudes and practical a-bility were analyzed.Results The hospice attitude score of 278 nurses in the hospice co-photography mode was(88.43±12.01),and the average score of entries was(3.54±0.48).The total score of the hospice Practical ability scale was(61.87±12.42),and the average score of the items was(3.64±0.73).Nurses'age,education background,previous experience in ca-ring for end-stage patients and their families,and self-assessment of competence in hospice care were the main influencing factors of nurses'practical ability score(all P＜0.05).There was a positive correlation between clinical nurses'practice ability score and hospice attitude score,the correlation coefficient r=0.176,P＜0.05.Conclusion Under the mode of hospice co-care,the attitude of nurses in Zhejiang Province is above the middle level,and the practical ability of nurses needs to be further improved,the higher the attitude of nurses,and the nurses'practical ability of hospice care is strong.Nursing managers should carry out professional training to promote the attitude of nursing staff,so as to improve the practical ability of nurses in hospice care.

Objective The purpose of this study was to provide a more effective method for researching the prevention and treatment of Graves'disease by comparing the effects of two plasmid vectors expressing the human thyrotropin receptor(TSHR)A subunit gene in inducing an animal model of Graves'disease via electroporation.Methods Plasmids pcDNA3.1-THSR A,and pTriEx1.1-THSR A expressing the TSHR A subunit were constructed and used to induce Graves'disease by intramuscular injection with immediate electroporation once every 3 weeks for a total of 4 times.Mice in the control group were injected with PBS.One week after the second electroporation,blood was collected to measure serum thyrotropin receptor antibody(TRAb).Three weeks following the last electroporation,echocardiography was performed on the mice.Mice were sacrificed 4 weeks after the last electroporation;blood,thyroid,and orbital tissues were collected;serum total thyroxine(TT4)was measured;and histological examination was performed.Results The average concentrations of serum TRAb in the pcDNA3.1-TSHR A group(n=15)and the pTriEx1.1-TSHR A group(n=13)were(6.9±2.0)U/L and(7.5±2.2)U/L,respectively.The latter was significantly higher than that in the control group(4.9±0.5)U/L(P=0.033).The average concentrations of serum TT4 in the pcDNA3.1-TSHR A group and pTriEx1.1-TSHR A group were(41.4±23.8)ng/mL and(63.2±53.7)ng/mL,respectively,both higher than that in the control group:(20.2±4.0)ng/mL(P＜0.01).Thyroid pathology showed thyroid follicular epithelial hyperplasia with T-cell infiltration in the model group.Echocardiography showed that the left ventricle mass in the pTriEx1.1-TSHR A group was higher than those in the control group(P=0.007)and pcDNA3.1-TSHR A group(P=0.012).Orbital pathology showed fibrotic changes in the extraocular muscles of mice in the model groups.Conclusions Both pcDNA3.1 and pTriEx1.1 expressing the TSHR A subunit were able to induce Graves'disease in mice by electroporation,and the efficiency of the two plasmids in inducing hyperthyroidism and Graves'ophthalmopathy was similar.The efficiency of pTriEx 1.1-TSHR A in inducing thyrotoxic heart disease was better than that of pcDNA3.1-TSHR A.
