ObjectiveTo explore the potential mechanism of Xiaoqinglong Decoction （小青龙汤， XD） in the treatment of allergic rhinitis. MethodsForty-five rats were randomly assigned to a control group， a model group， a loratadine group， low-， medium- and high-dose XD groups， and low-， medium- and high-dose Mahuang Decoction and Cang'erzi Powder （麻黄汤合苍耳子散， MDCP） groups. Except for the control group， rats were administered with ovalbumin （OVA） and aluminum hydroxide via intraperitoneal injection for 14 days to establish an allergic rhinitis model. After the 14th-day injection， nasal stimulation was continued with 20 μl of 10% OVA solution to maintain the model. Rats in the control group and the model group received 10 ml/（kg·d） of saline， whereas those in the loratadine group were administered with 0.9 mg/（kg·d） of loratadine. The low-， medium- and high-dose XD groups were administered XD at the dose of 2.7， 5.4， and 10.8 g/（kg·d）， respectively. The low-， medium- and high-dose MDCP groups were administered MDCP at the dose of 2.43， 4.86， and 9.72 g/（kg·d）， respectively. All treatments were administered by gavage once daily for 7 consecutive days. One hour after the final gavage， nasal symptom scores were recorded for all group of rats. The next day， serum levels of immunoglobulin E （IgE）， interleukin-4 （IL-4）， and interleukin-13 （IL-13） were measured. HE staining was used to observe the pathological morphology of the nasal mucosal tissue. Quantitative reverse transcription PCR （RT-qPCR） and Western Blot were performed to assess mRNA and protein expression of thymic stromal lymphopoietin （TSLP） and OX40 ligand （OX40L） in the nasal mucosa. ResultsCompared to the control group， total nasal symptom score in the model group significantly increased （P＜0.01）. HE staining revealed disrupted and adhered cilia， thickened basement membranes， and extensive inflammatory cell infiltration in the nasal mucosa. Serum levels of total IgE， IL-4， and IL-13， as well as TSLP and OX40L mRNA and protein expression in the nasal mucosa， were significantly elevated in the model group （P＜0.05 or P＜0.01）. Compared to the model group， the total nasal symptom scores in all drug intervention groups were significantly reduced； the serum total IgE levels in the loratadine group， the low- and medium-dose XD groups， and the low- and high-dose MDCP groups were significantly reduced； and the serum levels of IL-4 and IL-13 in the high-dose XD group and the high-dose MDCP group decreased （P＜0.05 or P＜0.01）. Nasal mucosal structure was improved. Except for the low-dose MDCP group， all other intervention groups showed a significant reduction in TSLP and OX40L mRNA expression in the nasal mucosa （P＜0.01）. All doses of XD and the medium- and high-dose MDCP groups significantly decreased the protein levels of TSLP and OX40L （P＜0.05）. The medium-dose XD group exhibited more improvement of nasal symptom scores and greater suppression of expression of TSLP and OX40L mRNA， and TSLP protein levels compared to the loratadine group （P＜0.05）. ConclusionXD may protect nasal mucosa of rats and alleviate allergic rhinitis by suppressing the TSLP/OX40L pathway， thereby attenuating Th2-mediated immune responses.

Rheumatoid arthritis （RA） is a chronic systemic autoimmune disease with complex pathogenesis， poor cure rate， long course of disease， and high disability rate， which seriously affects patients' quality of life. Western medicine treatment of RA mainly includes non-steroidal anti-inflammatory drugs， rheumatic drugs， glucocorticoids， biologics， and targeted small-molecule drugs， which have large side effects and many adverse reactions. Traditional Chinese medicine （TCM） has systematic， comprehensive， multi-target， and multi-mechanism advantages in the treatment of RA. Through the overall syndrome pattern identification， it is effective in relieving symptoms， delaying onset， and relieving pain in RA patients by dispelling wind and removing dampness， dissipating cold and dredging collaterals， clearing heat and removing toxin， resolving phlegm and removing blood stasis， and relaxing sinew and activating collaterals. In recent years， TCM has made remarkable progress in the intervention of RA by regulating the nuclear transcription factor-κB （NF-κB） signaling network. They include Toll-like receptor 4 （TLR4）， phosphoinositol 3 kinase （PI3K）/protein kinase B （Akt）， mitogen-activated protein kinase （MAPK）， Nod-like receptor protein 3 （NLRP3）， nuclear factor E₂ associated factor 2 （Nrf2）， Janus kinase 2 （JAK2）/signaling and transcriptional activator 3 （STAT3）， and Toll-like receptor 2 （TLR2）. The regulatory mechanism of NF-κB signaling network is complex： TLR4 is the upstream receptor of NF-κB， PI3K/Akt and MAPK pathways can not only regulate the activity of NF-κB， but also serve as its downstream effect pathway， Nrf2 and NF-κB often have antagonistic effects in the regulation of inflammatory response. Therefore， the research progress of regulating NF-κB signaling network by traditional Chinese medicine in the intervention of RA was summarized to provide a reference for the treatment of RA disease and the development of new drugs.

Objective To comparatively observe the value of 131I whole-body scanning(WBS)and 131I-SPECT/CT for evaluating residual thyroid tissue,lymph node and distant metastasis,as well as risk of recurrence of differentiated thyroid cancer(DTC)after surgical resection and initial radioactive iodine(RAI)treatment.Methods Totally 367 DTC patients who underwent initial RAI treatment after surgical resection and then 131I-WBS and 131I SPECT/CT scanning were retrospectively collected.131I-WBS and 131I SPECT/CT were compared for identifying residual thyroid,lymph node and distant metastases.According to follow-up results,the risk of DTC recurrence was evaluated based on 131I-WBS and 131I-SPECT/CT,respectively.Results Residual thyroid was detected in 353 cases and suspected in 3 cases with 131 I-WBS,which was diagnosed in 349 cases with 131I-SPECT/CT,and no significant difference was found between 2 methods(P=0.289).131I-WBS detected 36 cases with and suspected 67 cases with lymph node metastases,312 without distant metastases,while 131I-SPECT/CT diagnosed lymph node metastases in 52 cases;131I-WBS detected 20 cases with and suspected 35 cases with distant metastases,while 131I-SPECT/CT diagnosed 60 cases with distant metastases but could not diagnose in 3 cases,304 without distant metastases.The detection rate of 131I-SPECT/CT for lymph node and distant metastasis were both higher than that of 131I-WBS(P=0.018,P＜0.001).During follow-up period,there were 94 cases with low risk,155 with medium risk and 118 with high risk of DTC recurrence according to 131I-SPECT/CT,while 116 cases of low risk,137 of medium risk and 114 of high risk based on 131I-SPECT/CT,and the evaluating results were different between 2 methods in 40 cases(40/367,10.90％).Conclusion Compared with 131I-WBS,131I-SPECT/CT had better clinical value for evaluating lymph node and distant metastases and assessing recurrence risk of DTC after initial RAI treatment.

OBJECTIVE To understand the healthcare-seeking behavior of patients with AIDS co-infected with tu-berculosis and analyze the factors influencing delayed consultation and diagnosis,and to provide a theoretical basis for the implementation of interventional tuberculosis control measures.METHODS Two hundred and two patients with AIDS complicated with tuberculosis who were first admitted to Yunnan Infectious Diseases Hospital from Jan.2020 to Dec.2023 were selected,and their clinical data were collected through the inpatient medical record system.Multivariate logistic regression model was used to analyze the factors influencing delayed consultation and diagnosis.RESULTS Time of admission,place of residence,presence of lung cavities,distribution of lung lesions,intermediate hospital visited,sputum culture results,etiological situation,CD4+/CD8+cell ratio,and CD8+cell counts were the factors influencing delayed consultation(P<0.05).The initial diagnosis and Gene-Xpert results were the factors influencing delayed diagnosis(P<0.05).Multivariate logistic regression analysis showed that ad-mission in 2021(OR=3.842,95%CI:1.651-8.966),and presence of lung cavity(OR=8.007,95%CI:1.381-6.436),single lung lesion accumulation(OR=0.637,95%CI:0.049-8.267)were risk factors for delayed consultation.A 10%reduction in body mass(OR=2.070,95%CI:1.056-4.059)and negative Gene-Xpert re-sults(OR=1.667,95%CI:0.688-4.038)were risk factors for delayed diagnosis.CONCLUSIONS The issues of delayed medical consultation and diagnosis in patients with AIDS complicated with tuberculosis remain severe,with different factors influencing the delay.Special attention should be paid to the screening for latent tuberculosis infection in people infected with HIV.When experiencing suspicious symptoms,patients should go be encouraged to take exams at designated tuberculosis hospitals,repeatedly collect sputum samples and monitor changes in body mass,all of which are positively significant in reducing delays.

Objective:To analyze the problems existing in the cases of hospitals infringing upon patients′ informed consent right after the promulgation of the Civil Code of the People′ s Republic of China, and to provide reference for improving the legal system of informed consent. Methods:Search for judgment documents published from January 1, 2021 to June 30, 2023 on the China Judgment Document Network using the keyword " liability dispute for infringing on patients′ informed consent rights", and conduct descriptive and textual analysis on the cases in the judgment documents.Results:68 judgment documents were included in total.There were 11 judgment documents on infringement of patients′ right to informed consent, and all related cases have undergone appraisal. The content of infringement mainly included infringement of patients′ right to know their condition (12/20), infringement of patients′ right to access their medical records (6/20), infringement of patients′ right to bodily integrity without consent (2/20). There were 15 judgment documents which judge that the right of informed consent of patients wasn′t infringed, and only one case in the document has been appraised. The main focus of controversy was the issue of the priority of the exercise of the right to informed consent (2/15), the fulfillment of the obligation to inform the right to informed consent (5/15), the issue of surgery without notification (1/15), and the issue of determining the authenticity of medical records and providing medical materials (7/15).Conclusions:The legal protection of patients′ right to informed consent still faces judicial difficulties such as unclear order of the exercise of rights subject, insufficient specificity of the scope of the exercise of the right, conflicts between the right to informed consent and medical intervention, and lack of unified identification methods for infringement liability. It is suggested to standardize the order of the exercise subject of the right to informed consent, clarify the content of the obligation of the medical party to inform, construct a system for medical intervention, and unify the identification methods for disputes related to the right to informed consent.

Objective To screen self-assessed differentially expressed genes of cataracts and cataract-related genes from the International Mouse Phenotyping Consortium(IMPC),Mouse Genome Informatics(MGI),Cat-Map and GWAS Catalog and perform bioinformatics analysis,exploring potential pathogenic genes and signaling pathways in cataract patho-genesis.Methods The transparent anterior lens capsules of cataract patients and personnel in the control group were collected,total ribonucleic acid(RNA)was extracted,the library was constructed for sequencing,and differentially ex-pressed genes were analyzed.Data about the cataract phenotype-related genes was downloaded from IMPC,MGI and GWAS Catalog,the latest data from Cat-Map was downloaded,cataract susceptible gene annotation was performed,the characteristics of data from each database and the differentially expressed genes were analyzed,and Gene Ontology enrich-ment analysis,Kyoto Encyclopedia of Genes and Genomes enrichment analysis and protein-protein interaction(PPI)net-work analysis were carried out.Results Cataract susceptible single nucleotide polymorphism(SNP)annotation found a total of 21 potential target genes.IMPC,MGI,Cat-Map,and SNP target genes were enriched in the regulation of RNA poly-merase promoters,protein binding,cell division,peroxisome,and cell metabolism.The PPI network of core proteins fo-cused on the peroxisome family and function-related genes.The differentially expressed genes obtained from sequencing da-ta of transparent anterior lens capsules of cataract patients and personnel in the control group were enriched in mitogen-ac-tivated protein kinase(MAPK)signaling pathway,signal transduction,ion transport,metabolism,peroxisome,and cell adhesion pathways.Compared with the sequencing differentially expressed data of cataract patients,the differentially ex-pressed genes obtained from IMPC,MGI,Cat-Map,and SNP target gene sets were enriched in intracellular signal transduc-tion,MAPK signaling pathway,circadian rhythm,cyclic adenosine monophosphate,and calcium pathway.TRIM22,OAS3,EPSTI1,ZC3HAV1,SP110 and PARP12 protein networks of cataracts were identified based on the PPI networks.Conclu-sion The pathways and biological functions involved in the PPI networks of TRIM22,OAS3,EPSTI1,ZC3HAV1,SP110 and PARP12 may be a new pathogenic mechanism for cataracts.
