OBJECTIVE To explore the mechanism of Chaiqi yigan granules （CQYG） against liver cancer through the ferroptosis pathway. METHODS Network pharmacology combined with ferroptosis-related database was used to screen key targets and main effective components of CQYG against liver cancer via regulating ferroptosis； molecular docking technology was employed to analyze the binding ability of main active components to key targets. Human liver Huh-7 cells were divided into blank serum control （CON） group， CQYG drug-containing serum （CQYGKL） group， ferroptosis inducer （RSL3） group， mammalian target of rapamycin complex 1 （mTORC1） inhibitor （RMC-5552） group， mTORC1 agonist （CCT007093） group， and CCT007093+CQYGKL group. The levels of Fe 2+ ， malondialdehyde （MDA）， and glutathione （GSH） in the cells were detected in the former three groups； mRNA expressions of mammalian target of rapamycin （mTOR）， sterol regulatory element-binding protein 1 （SREBP1）， and stearoyl-CoA desaturase 1 （SCD1）， protein expressions of SREBP1 and SCD1 as well as phosphorylation levels of mTOR and ribosomal S6 kinase （S6K） proteins were detected in all groups. RESULTS Key targets of CQYG for anti-liver cancer through the ferroptosis pathway were mTOR， SREBP1， SCD1，etc. The main active components included quercetin， tanshinone Ⅱ A ， baicalein， etc. The binding energies of main active components to key targets were all less than －5 kJ/mol. Compared with CON group， the levels of Fe 2+ and MDA in the cells in CQYGKL group and RSL3 group were significantly increased， while the levels of GSH were significantly decreased （ P ＜0.05）. mRNA expressions of mTOR， SREBP1 and SCD1， protein expressions of SREBP1 and SCD1， as well as the phosphorylation levels of mTOR and S6K proteins were significantly decreased in the CQYGKL group， RSL3 group， and RMC-5552 group， whereas all the above indicators were significantly increased in the CCT007093 group （ P ＜0.05）. Compared with CCT007093 group， the changes in all the above indicators were significantly suppressed in the CCT007093+CQYGKL group （ P ＜0.05）. CONCLUSIONS CQYG may induce ferroptosis by inhibiting mTORC1/SREBP1/SCD1 axis， thereby exerting anti-liver cancer effects.

This paper discussed the differentiation and treatment of chemotherapy-induced nausea and vomiting （CINV） in traditional Chinese medicine， based on the theory of "yin qi descends， while all yang qi ascends” from Inner Canon of Yellow Emperor （《黄帝内经》）. The core pathogenesis of CINV is attributed to chemotherapy-induced injury to the middle jiao （焦）， resulting in the separation of yin and yang and loss of their mutual communication. Acute and explosive CINV is often characterized by "all yang qi ascends"， with stomach yang constraint transforming into fire， and qi counterflow leading to vomiting， which can be treated by unblocking stomach yang， draining fire and scattering the counterflow， with Huoxiang Zhengqi Powder （藿香正气散） and medicinals of clearing function. For delayed cases， which are often due to "yin qi descends"， and the accumulation of turbid yin obstructs and constrains the deficient yang， the treatment should focus on promoting qi flow to eliminate turbidity， unblocking and boosting yang qi， and Chengqi-series Formulas （承气类方） or Xiao Banxia Decoction （小半夏汤） can be considered. Refractory and anticipated cases usually involve stomach-kidney deficiency and zang-fu （脏腑） organs disharmony， making yin and yang difficult to restore balance， for which the treatment should focus on nourishing both the stomach and kidneys and harmonize the zang-fu organs， with formulas such as Fuzi Lizhong Decoction （附子理中汤） or Xiaoyao Powder （逍遥散） modified as appropriate.

ObjectiveTo analyze the etiological characteristics and risk factors of autosomal dominant polycystic kidney disease （ADPKD） complicated with urinary tract infection （UTI）. MethodsA retrospective analysis was performed on 244 patients with ADPKD admitted to the Department of Nephrology. The patients were stratified into a study group （n=138） and a control group （n=106） according to the presence or absence of concurrent UTI. All patients in the study group underwent etiological testing and drug susceptibility testing. Clinical data of both groups were collected to identify the risk factors for ADPKD complicated with UTI. ResultsA total of 105 pathogens were detected in 138 cases in the study group， including 79 Gram-negative bacteria， 20 Gram-positive bacteria and 6 fungi. Escherichia coli showed a relatively high resistance rate to ampicillin， piperacillin and ciprofloxacin. Enterococcus faecalis had a relatively high resistance rate to tetracycline. There were statistically significant differences between the study group and the control group in terms of gender， history of urinary tract infection， C-reactive protein （CRP）， increased urine red blood cells， increased urine white blood cells， increased percentage of neutrophils， blood sodium， blood calcium， total cholesterol， serum iron and transferrin saturation （P<0.05）. Multivariate binary Logistic regression analysis revealed that female gender （OR=2.236， P=0.004）， history of urinary tract infection （OR=2.383， P=0.002）， increased urine white blood cells （OR=2.726， P=0.001）， increased percentage of neutrophils （OR=1.040， P=0.010）， elevated C-reactive protein （OR=1.011， P=0.007） and elevated blood calcium （OR=4.389， P=0.024） were risk factors of urinary tract infection in ADPKD patients （P<0.05）. ConclusionThe main pathogens of UTI in patients with ADPKD are Gram-negative bacteria. Female， previous history of urinary tract infection， urinary leukocytosis， increased percentage of neutrophils， increased CRP and increased serum calcium are risk factors of UTI.

Liver transplantation is the preferred treatment for end-stage liver disease, but recipients require long-term immunosuppressive therapy to control rejection, which may lead to complications and affect their long-term survival. Immune tolerance refers to the ability of organ transplant recipients to maintain their immune system's tolerance to the graft without relying on long-term immunosuppressants. Immune tolerance is an ideal goal pursued in the field of organ transplantation, which can reduce adverse drug reactions and improve long-term survival rates. Cell therapy has emerged as a promising strategy to induce such tolerance after liver transplantation. Therefore, this article reviews the application progress of cell therapies such as regulatory T cells, regulatory dendritic cells, mesenchymal stem cells, hematopoietic stem cells, etc. in inducing immune tolerance after liver transplantation, in order to provide reference for the clinical application of immune tolerance induction after liver transplantation.

Objective To analyze the epidemiologic burden of colorectal cancer in Xishan District, Kunming City, Yunnan Province from 2018 to 2020. Methods Indicators of epidemiologic burden were calculated, including incidence rate, mortality rate, age-specific incidence/mortality rates, potential years of life lost (PYLL), and disability-adjusted life years (DALY) based on the National Disease Control and Prevention Center’s "Cancer Information Registration and Reporting System" and "Cause of Death Registration System". Results From 2018 to 2020, the ASR (China) for the incidence of colorectal cancer in Xishan District, Kunming City increased from 25.27/10⁵ to 26.29/10⁵, while the ASR (China) for mortality decreased from 17.11/10⁵ to 16.03/10⁵. The PYLL in 2018–2020 were 1399.63, 1376.78, and 1571.56 person-years, respectively, whereas the DALY in 2018–2020 were 1927.74, 1875.05, and 1945.17 person-years, respectively. The morbidity, mortality, PYLL, and DALY were generally higher in males than in females over 45 years of age. Conclusion Given the parallel trends of persistent incidence risk and steadily declining mortality for colorectal cancer in Xishan District, Kunming City, a three-tier prevention and control system centered on "lifestyle intervention–regular screening–positive case tracking" should be established, with a focus on covering high-risk populations, particularly males over 45 years of age.

AIM: To evaluate the postoperative clinical efficacy of non-diffractive extended depth of focus intraocular lens(EDOF IOL)in patients with highly myopic cataract(HMC).METHODS:A retrospective analysis was conducted on the clinical data of patients diagnosed with HMC at the hospital from January 2022 to December 2024. Patients were divided into an observation group [undergoing femtosecond laser-assisted cataract surgery(FLACS)combined with non-diffractive EDOF IOL implantation] and a control group(undergoing FLACS combined with aspheric monofocal IOL implantation)according to the type of implanted IOL. Postoperative visual acuity(LogMAR), visual quality, and patient satisfaction were compared between the two groups.RESULTS: A total of 33 patients(47 eyes)were finally included in this study, including 10 patients(17 eyes)in the observation group and 23 patients(30 eyes)in the control group. The observation group had a median age of 59.0(52.8, 63.8)y, with 8 males(13 eyes)and 2 females(4 eyes). The control group had a median age of 56.0(53.5, 60.0)y, with 13 males(17 eyes)and 10 females(13 eyes). At 3 mo postoperatively, the best-corrected distance visual acuity(BCDVA)was 0.10(0.08, 0.12)in the observation group and 0.20(0.10, 0.40)in the control group(P=0.586). However, the best-corrected intermediate visual acuity(BCIVA)[0.10(0.10, 0.10)vs 0.50(0.40, 0.90), P=0.032] and best-corrected near visual acuity(BCNVA)[0.20(0.18, 0.20)vs 0.60(0.45, 1.45), P=0.044] in the observation group were significantly better than those in the control group. The defocus curve showed that the uncorrected visual acuity(UCVA)in the observation group was relatively stable within the range of -2.00 to +1.00 D, which was superior to that in the control group. Postoperative questionnaires showed that the spectacle independence rate(76%)and overall satisfaction(88%)in the observation group were significantly higher than those in the control group(10% and 60%, respectively).CONCLUSION: Non-diffractive EDOF IOL significantly improves intermediate and near visual acuity, reduces spectacle dependence, and maintains distance visual acuity by extending the depth of focus, providing better postoperative visual quality and life satisfaction for HMC patients.

In the context of the modernization of traditional Chinese medicine （TCM）， the inheritance of the experiences of famous doctors faces significant challenges due to its complex nonlinear characteristics and dynamic evolution. There are still issues in the current inheritance system， such as the homogenization of talent cultivation models， lack of standardized mentoring practices， and monotonous evaluation method， which hinder the systematic inheritance and innovative development of famous doctors' experiences. Based on a systematic review of the current state of artificial intelligence （AI）-assisted inheritance of famous doctors' experiences， this study explores innovative pathways for deep integration of modern information technologies with famous doctors' experiences from key dimensions， including data authenticity assurance， interdisciplinary collaboration mechanisms， and the establishment of dynamic inheritance standards. It proposes a paradigm shift in the inheritance of TCM famous doctors' experiences in the AI era， aiming to build a new TCM inheritance system of "digital intelligence empowerment and cross-disciplinary innovation"， providing theoretical support and practical pathways for the inheritance of famous doctors' experiences in TCM.

OBJECTIVE To investigate the neuroprotective effect and mechanism of eleutheroside B （ELB） on Parkinson’s disease （PD） model mice by regulating the IκB kinase β （IKKβ）/nuclear factor-κB （NF-κB） signaling pathway. METHODS Fifty mice were randomly divided into normal control group， model group， positive control group （selegiline hydrochloride， 10 mg/kg）， and ELB low-dose and high-dose groups （80， 160 mg/kg）， with 10 mice in each group. Each group was given relevant medicine or normal saline intragastrically for 14 consecutive days. Starting from the 10th day of administration， the model group and all administration groups were intraperitoneally injected with 1-methyl-4-phenyl-1，2，3，6-tetrahydropyridine （MPTP） 30 mg/kg， for five consecutive days to establish the chronic PD model. After the last administration for 24 h， six mice were randomly selected from each group to test their behavioral abilities； detect the levels of interleukin-1β （IL-1β）， IL-10， tumor necrosis factor-α （TNF-α） in brain tissue and their mRNA expressions were measured， and positive expression of tyrosine hydroxylase （TH）， protein expressions of TH， α -synuclein （ α -syn）， ionized calcium-binding adaptor molecule 1 （Iba-1）， as well as phosphorylation levels of IKKβ and NF-κB p65 proteins in the brain tissue were detected. The ultrastructure of neurons in substantia nigra was observed. RESULTS Compared with the model group， rotarod endurance time and climbing score of each administration group （except for the ELB low-dose group） were increased significantly （ P ＜0.05）， while the levels and mRNA expressions of IL-1β， TNF-α， α -syn， and Iba-1， as well as phosphorylation levels of IKKβ and NF-κB p65 proteins in brain tissue were decreased significantly （except for TNF-α in the ELB low-dose group）. Conversely， the level and mRNA expression of IL-10 （except for the ELB low-dose group）， TH positive expression and protein expressions were significantly increased （ P ＜0.05）. Typical neurodegenerative pathological changes， such as neuronal karyopyknosis， mitochondrial swelling and vacuolization， and endoplasmic reticulum dilation， all showed varying degrees of improvement. CONCLUSIONS ELB may exert neuroprotective effects by inhibiting the activation of the IKKβ/NF-κB signaling pathway， alleviating inflammatory responses， reducing abnormal α -syn aggregation and neuronal loss， and further improving motor dysfunction in PD mice.

OBJECTIVE: To explore the clinical phenotypes and genetic characteristics of five children with Lamb-Shaffer syndrome (LAMSHF). METHODS: Five children with LAMSHF diagnosed at the Department of Pediatrics, the First Medical Center of Chinese PLA General Hospital from April 2021 to December 2024 were selected as study subjects. Clinical data of the children was collected. Genomic DNA was extracted from peripheral blood samples of the children and their parents. Whole exome sequencing (WES) was carried out to screen for variants. This study was approved by the Medical Ethics Committee of the Chinese PLA General Hospital (Ethics No.: S2025-411-01). RESULTS: All five children had presented with global developmental delay. Among them, two had manifestations of autism spectrum disorder, two had abnormal electroencephalogram findings, four had abnormal MRI results, and two had ocular abnormalities. WES has detected five novel variants in the SOX5 gene. Among these, c.1771G>C (p.Gly591Arg) was unreported previously. Sanger sequencing confirmed that none of the parents had carried the same variants, suggesting that they were all de novo variants. According to the guidelines from the American College of Medical Genetics and Genomics (ACMG), two nonsense variants and one missense variant were classified as pathogenic, whilst two missense variants were classified as likely pathogenic. CONCLUSION This study has clarified the correlation between the clinical phenotypes of five children with LAMSHF and variants of the SOX5 gene, which expanded the mutational spectrum of the SOX5 gene and provided a basis for the clinical diagnosis and genetic counseling.

Objective To analyze survival outcomes and influencing factors among patients with colorectal cancer in Yunnan Province. Methods Clinical data were retrospectively collected from 4 892 patients with colorectal cancer. Survival data were obtained through follow-up. Overall survival (OS) was calculated by using the Kaplan-Meier method. Univariate analysis was performed by applying the log-rank test. Meanwhile, multivariate analysis employed the Cox proportional hazards regression model. Results The 1-, 3-, 5-, and 10-year OS rates for the entire cohort were 91.90%, 74.40%, 64.40%, and 28.70%, respectively. Univariate analysis revealed that age, ethnicity, region, differentiation grade, TNM stage, clinical stage, metastatic status, histological type, and treatment modality (chemotherapy, radiotherapy, and surgery) were associated with patient prognosis (all P<0.05). Multivariate analysis identified age (HR=1.250), region (HR=1.262), differentiation grade (HR=0.761), clinical stage (HR=3.128), and treatment modality (chemotherapy, HR=0.644; radiotherapy, HR=1.605; surgery, HR=0.384) as independent factors affecting survival prognosis in patients with colorectal cancer (all P<0.001). Conclusion Age, region, clinical stage, and treatment modality are independent factors influencing survival among patients with colorectal cancer in Yunnan Province. In clinical practice, these factors should be integrated to develop individualized prevention and treatment strategies, thereby improving patient outcomes.
