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.

Objective To analyze the postoperative complications and survival outcomes of elderly patients with renal cell carcinoma undergoing laparoscopic surgery, and to identify the influencing factors, so as to provide reference for improving the safety of laparoscopic surgery in such patients. Methods A retrospective analysis was conducted on the clinical, surgical, and pathological data of 153 patients aged ≥75 years who underwent laparoscopic nephrectomy for renal cell carcinoma at our hospital during 2012 and 2025.Logistic regression analyses were performed to identify factors influencing postoperative complications, and a nomogram was constructed and validated to predict the complications.Kaplan-Meier method was used to draw the survival curve, and the effects of different surgical approaches on the prognosis and the survival difference in the age subgroups (75-＜80 years, ≥80 years) were analyzed.Cox regression analyses were conducted to determine factors affecting survival outcomes. Results Among the 153 patients, 15 developed postoperative complications, including 5 severe cases. Multivariate logistic regression identified Charlson Comorbidity Index (CCI) ≥3 and prolonged operation time as independent risk factors for postoperative complications (P＜0.05).The C-index of the logistic regression model constructed based on these factors (age, CCI≥3 and operation time) was 0.77 (95%CI:0.64-0.90), with an average absolute error of 1.6%.Subgroup analysis revealed superior overall survival in patients aged 75-＜80 years undergoing partial nephrectomy compared to radical nephrectomy (P=0.005 6).No statistically significant difference in overall survival was observed among patients ≥80 years who received different surgical approaches (P=0.062).Multivariate Cox regression analysis identified preoperative low albumin levels, preoperative renal insufficiency, tumor diameter＞4 cm, and pathological stage as independent risk factors for overall survival (P＜0.05). Conclusion Laparoscopic surgery is safe and effective for elderly patients with renal cell carcinoma, with survival outcomes correlated to nutritional status, renal function, tumor size and pathological staging.Patients aged ≥80 years still derive surgical benefit, and no survival differences exist between different surgical approaches in this age group.

Core fucosylation, catalyzed exclusively by fucosyltransferase 8 (FUT8), is an evolutionarily conserved post-translational modification that has emerged as a central regulatory hub linking liver homeostasis, chronic disease progression, and malignant transformation. Liver diseases, particularly hepatocellular carcinoma, remain a leading global health burden characterized by late diagnosis, limited therapeutic options, and poor overall survival. While aberrant glycosylation is now recognized as a hallmark of cancer and inflammatory disorders, existing research on FUT8-mediated core fucosylation in liver diseases remains fragmented: the dynamic functional switch of FUT8 from a homeostatic regulator to a pathological driver across the full disease continuum has not been systematically delineated, and the integrated mechanisms by which core fucosylation modulates oncogenic signaling, metabolic reprogramming, and immune evasion remain poorly understood. This review synthesizes recent advances to establish a unified framework for understanding the dual role of core fucosylation in liver physiology and pathology, and evaluates its translational potential for precision medicine. At the molecular level, FUT8’s unique catalytic specificity makes core fucosylation an irreplaceable modification, as evidenced by the perinatal lethality and severe organ dysfunction in Fut8 knockout mice. In hepatocellular carcinoma, genomic amplification of guanosine 5'-diphosphate-fucose biosynthetic enzymes provides metabolic support for aberrant core fucosylation. FUT8 expression is tightly regulated by a multi-layered network: transcriptional activation via Wnt/β‑catenin and wild-type p53, epigenetic upregulation by lncRNAs, post-transcriptional repression by miR-122-5p and miR-34a, and virus-specific induction by hepatitis B virus/hepatitis C virus. Physiologically, core fucosylation maintains liver homeostasis through four core mechanisms: it acts as a molecular switch for epidermal growth factor receptor/hepatocyte growth factor receptor signaling to enable liver regeneration; directs polarized secretion of hepatocyte-derived glycoproteins into bile ducts; modulates cholesterol metabolism via the hepatocyte nuclear factor 1α-proprotein convertase subtilisin/kexin type 9-low density lipoprotein receptor axis; and regulates aging through insulin‑like growth factor 1 receptor signaling. Pathologically, core fucosylation exhibits context-dependent dual functions: in liver fibrosis, FUT8 upregulation in hepatic stellate cells forms a negative feedback loop that limits excessive fibrogenesis; in hepatocellular carcinoma, however, aberrant FUT8 overexpression drives cell-autonomous malignancy by constitutively activating epidermal growth factor/hepatocyte growth factor receptor, transforming growth factor‑β/Smad, and Wnt/β‑catenin pathways, while simultaneously establishing a multi-layered immune evasion network by stabilizing programmed cell death ligand 1 and cluster of differentiation 47, and impairing natural killer cell homeostasis via interleukin‑2 receptor β glycosylation. Clinically, stage-specific core fucosylation biomarkers enable non-invasive monitoring of liver disease progression: low molecular mass kringle-Fc fusion protein outperforms conventional markers for early fibrosis detection, while alpha-fetoprotein-L3 and novel glycopeptides (α‑2‑macroglobulin N‑linked glycosylation site 1424, lumican core fucosylated peptide) significantly improve early hepatocellular carcinoma diagnosis, especially in alpha-fetoprotein-negative patients. Next-generation detection technologies (chemoenzymatic labeling, site-specific mass spectrometry) overcome the specificity limitations of traditional lectin assays. Therapeutically, four promising strategies are emerging: small-molecule FUT8 inhibitors, afucosylated antibodies with enhanced antibody‑dependent cellular cytotoxicity, Fuc-modified targeted drug delivery systems, and core fucose-specific lectins for NASH treatment. The core challenge for clinical translation lies in FUT8’s inherent “double-edged sword” effect, as systemic inhibition disrupts its essential physiological functions beyond pathological roles. Long-term systemic FUT8 blockade not only impairs post-injury liver regeneration by abrogating epidermal growth factor/hepatocyte growth factor receptor signaling but also disrupts cholesterol homeostasis via the hepatocyte nuclear factor 1α-proprotein convertase subtilisin/kexin type 9-low density lipoprotein receptor axis, leading to dyslipidemia and altered bile secretion. Critically, it compromises immune surveillance by destabilizing interleukin‑2 receptor β on natural killer cells, reducing their cytotoxic activity against malignant and virally infected cells, and impairs IgG Fc-mediated effector functions, increasing susceptibility to infections. This fundamental trade-off between therapeutic efficacy and systemic toxicity necessitates a paradigm shift from non-specific global inhibition to precision modulation of pathological core fucosylation. By addressing these critical challenges, FUT8-mediated core fucosylation has the potential to transform liver disease management from late-stage intervention to early detection and precision therapy, ultimately improving patient outcomes and reducing the global burden of liver diseases.

BACKGROUND:At present,osteoarthritis has become a major disease affecting the quality of life of the elderly,and the therapeutic effect is poor,often focusing on preventing the disease process,and the pathogenesis of osteoarthritis is still not fully understood.Bioinformatics analysis was carried out to explore the main pathogenesis of osteoarthritis and related mechanisms of gene coding regulation. OBJECTIVE:To screen core differential genes with a major role in osteoarthritis by gene expression profiling. METHODS:Datasets were downloaded from the Gene Expression Omnibus(GEO):GSE114007,GSE117999,and GSE129147.Differential genes in the GSE114007 and GSE117999 data collections were screened using R software,performing differential genes to weighted gene co-expression network analysis.The module genes most relevant to osteoarthritis were selected to perform protein interaction analysis.Candidate core genes were selected using the cytocape software.The candidate core genes were subsequently subjected to least absolute shrinkage and selection operator regression and COX analysis to identify the core genes with a key role in osteoarthritis.The accuracy of the core genes was validated using an external dataset,GSE129147. RESULTS AND CONCLUSION:(1)A total of 477 differential genes were identified,265 differential genes associated with osteoarthritis were obtained by weighted gene co-expression network analysis,and 8 candidate core genes were identified.The least absolute shrinkage and selection operator regression analysis finally yielded a differential gene ASPM with core value that was externally validated.(2)It is concluded that abnormal gene ASPM expression screened by bioinformatics plays a key central role in osteoarthritis.

Objective:To analyze the iodine nutrition status of pregnant women in Weihai City before and after (2022, 2023) the iodine deficiency disorders (IDD) intervention, evaluate the effectiveness of intervention measures, and provide a scientific basis for adjusting IDD prevention strategies in the city.Methods:In May 2023, the intervention action of IDD was carried out for pregnent women in Weihai City. In April 2022 and December 2023, respectively, a cross-sectional survey method was conducted in four districts (cities) of Weihai City. Each district (city) was divided into five areas (east, west, south, north, and central) each year, and one township (street) was selected from each areas. At least 20 pregnant women were selected from each township (street) as survey subjects, and their household salt samples and random urine samples were collected to measure salt iodine and urinary iodine concentrations, and to compare the test results.Results:A total of 922 household salt samples were tested, including 530 iodized salt samples and 469 qualified iodized salt samples. The median salt iodine was 24.00 mg/kg. The coverage rate of iodized salt, the qualified rate of iodized salt, and the consumption rate of qualified iodized salt were 57.48%, 88.49%, and 50.87%, respectively. No significant difference was observed in medians salt iodine between 2022 (24.26 mg/kg) and 2023 (24.00 mg/kg, Z = - 1.58, P = 0.113). However, the coverage rate of iodized salt and the consumption rate of qualified iodized salt in 2023 werehigher than those in 2022 [73.72% (373/506) vs 37.74% (157/416), 65.22% (330/506) vs 33.41% (139/416), χ 2 = 120.90, 92.40, P < 0.001]. A total of 922 urine samples were collected from pregnant women, with a median urinary iodine of 135.90 μg/L. The median urinary iodine of pregnant women in 2022 was 113.55 μg/L. There was a statistically significant difference in medians urinary iodine among different regions ( H = 27.91, P < 0.001). The median urinary iodine of pregnant women in 2023 was 153.00 μg/L. There was no statistically significant difference in medians urinary iodine among different regions ( H = 3.33, P = 0.343). The medians urinary iodine of pregnant women in Huancui District, Wendeng District, and Rushan City in 2023 (156.60, 155.00, 140.85 μg/L) were higher than those in 2022 (93.60, 110.00, 110.70 μg/L), and the differences were statistically significant ( Z = - 5.44, - 4.92, - 5.99, P < 0.001). The median urinary iodine of pregnant women in Weihai City in 2023 showed a statistically significant difference compared to 2022 ( Z = - 7.62, P < 0.001). Conclusions:The IDD intervention measures in Weihai City have achieved good results, and the coverage of iodized salt, the consumption rate of qualified iodized salt, and the iodine nutrition level of pregnant women have improved. We should continue to implement intervention measures, improve the iodine nutrition level of key populations, and maintain a sustained elimination of IDD.

Objective:To investigate the current situation and influencing factors of work ability in gynecological cancer patients, so as to provide a reference for occupational rehabilitation management of cancer patients.Methods:A total of 183 gynecological cancer patients who visited the gynecological oncology outpatient department of Women′s Hospital of Nanjing Medical University from November 2022 to March 2023 were selected by the convenience sampling. The General Information Questionnaire, Return-to-Work Self-efficacy Questionnaire, Social Support Rating Scale, the European Organization for Research and Treatment of Cancer Quality of Life Quesionnaire Core 30, Work Ability Index were selected for cross-sectional investigaton. The multiple linear regression analysis was used to explore the influencing factors of work ability in gynecological cancer patients.Results:A total of 189 questionnaires were sent out in this study, and 183 were effectively collected, with an effective recovery rate of 96.83% (183/189). The patients were (44.64 ± 7.06) years old. The scores of the patients were (27.77 ± 7.58) points on Work Ability Index, (4.72 ± 1.14) points on Return-to-Work Self-efficacy Questionnaire, (86.93 ± 23.44) points on Social Support Rating Scale, (79.46 ± 19.53) points on overall health status area and (41.23 ± 27.80) points on the field of fatigue symptoms area of the European Organization for Research and Treatment of Cancer Quality of Life Quesionnaire Core 30. Multiple linear regression analysis showed that fatigue, comorbidities, clinical stage of disease, primary treatment, per capita monthly income of families, return-to-work self efficacy and job nature were independent influencing factors of work ability in gynecological cancer patients ( t values were -10.47-2.86, all P<0.05), which explained 67.9% of the total variance. Conclusions:Clinical medical staff should pay attention to the influencing factors that affect work ability in gynecological cancer patients, in order to take targeted occupational rehabilitation measures to improve their work ability.

Objective:To compare the clinicopathological characteristics and prognostic outcomes between patients with clear cell renal cell carcinoma(ccRCC)and non-clear cell renal cell carcinoma(nccRCC)accompanied by venous tumor thrombus.Methods:A retrospective analysis was conducted on clinical and pathological data from patients with RCC and venous tumor thrombus treated in the Depart-ment of Urology at Peking University Third Hospital between January 2014 and February 2024.Patients were stratified into two groups based on pathological type:ccRCC and nccRCC.Comparisons of baseline characteristics,intraoperative situation,and prognosis between the two groups were performed using t-tests,Mann-Whitney U tests,chi-square tests,and Log-rank tests.Survival curves were generated using the Kaplan-Meier method.Results:A total of 437 patients were included,with a median age of 58 years,including 317 males and 120 females.The cohort comprised 366 cases of ccRCC and 71 cases of nccRCC.The non-clear cell group included 38 cases(53.5％)of papillary renal cell carcinoma,2 cases(2.8％)of chromophobe renal cell carcinoma,11 cases(15.5％)of unclassified renal cell carcinoma,19 cases(26.8％)of molecularly defined renal cell carcinoma,and 1 case(1.4％)of collecting duct carcinoma.Compared with the clear cell renal carcinoma group,patients in the non-clear cell carcinoma group demonstrated a younger age at diagnosis(59 years vs.55 years,P=0.010),larger tumor size(8.4 cm vs.9.5 cm,P=0.025),higher rates of lymph node metastasis(56.8％vs.70.6％,P=0.034),more advanced tumor thrombus(P＜0.001)and pathological grading(P=0.010),longer surgical duration(272 minutes vs.289 minutes,P=0.023),and shorter overall survival(80 months vs.35 months,P＜0.001).Multivariate Cox analysis indicated that histologic type,distant metastasis,tumor thrombus grading,and sarcomatoid/rhabdoid differentiation were prognostic factors in the renal cell carcinoma patients with venous tumor thrombus.No significant differences were observed between the two groups in terms of gender,body mass index,tumor laterality,distant metastasis,sarcomatoid or rhabdoid differentiation,American Society of Anesthesiologists(ASA)score,surgical approach,conversion to open surgery,blood loss,or transfusion of red blood cells and plasma.Conclusion:Compared with pa-tients with clear cell renal carcinoma and venous tumor thrombus,those with non-clear cell carcinoma and venous tumor thrombus exhibit earlier onset,more aggressive disease progression,and poorer prognosis.

Objective:To summarize the progress in the research of textual quality evaluation of health-related media reports.Methods:A systematic literature retrieval about textual quality evaluation of health-related media reports based on PubMed, Web of Science, Embase, Wanfang database, and China National Knowledge Infrastructure was conducted. Information regarding the textual quality definition, evaluation dimensions, indicators and methods of included papers was extracted.Results:A total of 29 study papers were included in this analysis, in which 26 were about retrospective textual quality evaluation of health-related media reports, and 3 were about the model or tool development for textual quality evaluation of health-related media reports. The topics of news reports included: 16 studies on injury, 3 on general health, 3 on infectious disease, 3 on cancer screening and treatment, 3 on chronic non-communicable disease, and 1 on medication risk. The definition of textual quality of health-related media reports and the dimensions of the quality evaluation varied across the studies. The quality evaluation indicators of media reports can be divided into three categories: availability of surveillance information, availability of professional information, and adherence to principles of media reporting. Most studies conducted the quality evaluation manually, with only 2 studies employing semi-automated or automated evaluation methods.Conclusions:No unified definition, set of dimensions, indicators, or automated algorithms exist for evaluating the textual quality of health-related media reports, which limits assessing massive news data effectively. It is necessary to conduct methodological studies on the textual quality evaluation of health-related media reports based on journalism and communication theory, infodemiology, deep learning, natural language processing, text mining, as well as specific disease and injury prevention theory.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Aim To observe the interventional effects of Polygala fallax Hemsl.(PFH)on diabetic kidney disease(DKD)rats and the regulatory mechanism of ferroptosis.Methods Thirty-six SD rats were ran-domly divided into the control group,DKD group,fer-rostatin-1(Fer-1)group,PFH-L group,PFH-M group,and PFH-H group,with six rats in each group.Model-ing was induced by a one-time intraperitoneal injection of 35 mg·kg-1 streptozocin(STZ)in combination with high-sugar and high-fat feed.Ferrostatin-1(25μmol·kg-1)was injected intraperitoneally in Fer-1 group.The PFH-L,PFH-M,and PFH-H groups were gavaged with 50,100 and 200 mg·kg-1 of alcoholic extracts of PFH respectively,and the control and DKD groups were gavaged with an equal volume of distilled water once a day for eight weeks.At the end of drug administration,blood glucose,24h-UP,BUN and Scr levels were measured in each group of rats.HE stai-ning and Masson staining were used to observe renal histopathological changes.ELISA was employed to de-termine the levels of total iron,MDA and GSH activity.IHC was used to observe the expression of Nrf2,SLC7A11,and GPX4 in renal tissues.Western blot was used to detect the protein expression of COL1A1,α-SMA,TGF-,FTH-1,TFR-1,Nrf2,SLC7A1 1,GPX4,in renal tissues.RT-qPCR was used to detect the ex-pression levels of Nrf2,SLC7A11,GPX4 mRNA in re-nal tissues.Results Compared with the control group,blood glucose,24h-UP,BUN,Scr increased(P＜0.05);glomerular volume increased,tubular dilata-tion and collagen fiber deposition were obvious;total i-ron,MDA content increased and GSH activity de-creased(P＜0.05);there was increased protein ex-pression of COL1A1,α-SMA,TGF-β,TFR-1 and de-creased protein expression of FTH-1(P＜0.01);there was decreased mRNA and protein expression of Nrf2,SLC7A11,GPX4 in DKD group rats(P＜0.01).Compared with the DKD group,blood glucose,24h-UP,BUN and Scr decreased(P＜0.05);renal tissue le-sions were significantly reduced;total iron and MDA content decreased,and GSH activity increased(P＜0.05);COL1A1,α-SMA,TGF-β,and TFR-1 protein expression decreased and FTH-1 protein expression in-creased(P＜0.05,P＜0.01);Nrf2,SLC7A11,GPX4 mRNA and protein expression increased in Fer-1 and PFH dose groups(P＜0.05,P＜0.01).Conclusions PFH attenuates renal histopathological injury in DKD rats,and the mechanism may be related to the regula-tion of the Nrf2/SLC7A11/GPX4 signaling pathway.
