Objective To explore the medication characteristics of Yan Guangjun in treating cancer-related fatigue in colorectal cancer through data mining.Methods The cases of intestinal cancer-related fatigue treated by Yan Guangjun in outpatient clinics were collected,and the frequency and properties of drugs were summarized;the correlation rules,complex networks and cluster analysis were carried out on the Chinese medicine in the prescription.Results A total of 61 prescriptions were included in the study,covering 146 types of traditional Chinese medicines.The most frequently used category of drugs was tonics,with the most commonly used drugs being Baizhu,Fuling,Gancao,Huangqi,and Dangshen,etc.The dominant properties and flavors of the drugs were warm,cold,neutral,sweet,bitter,and pungent.The drugs meridians were attributed mainly the liver,spleen,and kidney meridians.Six different combinations of traditional Chinese medicine formulas were identified.Conclusion Yan Guangjun's treatment of cancer-related fatigue in colorectal cancer is fundamentally based on strengthening the spleen and replenishing Qi,warming Yang and nourishing the kidneys,while also nourishing Yin and enriching blood to counteract the dryness of warming yang.During the process of tonifying the body's vital energy,detoxification and anticancer effects are also achieved,combining both attack and tonification.

Objective:To compare the clinical efficacy and adverse events of different postoperative radiotherapy strategies (adjuvant radiotherapy versus salvage radiotherapy) and different irradiation fields (prostate bed versus prostate bed + pelvic radiation) in patients after radical prostatectomy for prostate cancer.Methods:This retrospective analysis included clinical data from 115 patients with localized or locally advanced prostate cancer who received intensity-modulated radiotherapy (IMRT) after radical prostatectomy at Beijing Hospital between March 2014 and September 2023. Among them, 40 patients received adjuvant radiotherapy, and 75 received salvage radiotherapy. And 74 patients received irradiation to both the prostate bed and pelvic (prostate bed + pelvic radiation group), while 41 patients received irradiation to the prostate bed alone (prostate bed irradiation group). Comparison was made between the adjuvant radiotherapy group and salvage radiotherapy group, as well as between prostate bed + pelvic radiation group and prostate bed irradiation group, in terms of overall survival (OS), progression-free survival (PFS), locoregional recurrence-free survival (LRRFS), and the incidence of adverse events. Clinical characteristics were compared using the chi-square test. Survival rates were calculated using the Kaplan-Meier method and compared using the log-rank test. Prognostic factors affecting survival were analyzed using Cox multivariate regression.Results:The median follow-up duration was 73.1 months. The 5-year OS, PFS and LRRFS rates for the entire cohort were 96.4%, 86.4%, and 93.2%, respectively. A total of 59 patients (51.3%) experienced grade 1-2 acute radiotherapy-related adverse events, while 43 patients (37.4%) experienced grade 1-2 late radiotherapy-related adverse events. No grade ≥ 3 late adverse events were observed. There were no statistically significant differences in OS, PFS, or LRRFS between the adjuvant and salvage radiotherapy groups ( P = 0.807, 0.996, and 0.976, respectively), or in the incidence of grade 1-2 acute or late adverse events ( P > 0.05). The OS rate in the prostate bed + pelvic radiation group was significantly lower than that in the prostate bed irradiation group ( P = 0.036), while no significant differences were found in PFS or LRRFS ( P = 0.109 and 0.190, respectively), or in the incidence of grade 1-2 acute or late adverse events ( P > 0.05). Multivariable analysis showed no statistically significant differences in OS, PFS, or LRRFS between the adjuvant and salvage radiotherapy groups, or between the prostate bed and prostate bed + pelvic irradiation groups ( P = 0.756, 0.341, 0.605; 0.938, 0.987, 0.605, respectively). Conclusions:In the era of modern IMRT, both adjuvant and salvage radiotherapy, as well as prostate bed and prostate bed + pelvic irradiation, demonstrate similar efficacy and safety profiles after radical prostatectomy for prostate cancer. Treatment outcomes were favorable, and adverse events were minimal.

Objective:To investigate the clinical characteristics and prognosis of follicular lymphoma (FL) patients with different primary sites using the Surveillance, Epidemiology, and End Results (SEER) database.Methods:Clinical data of 7167 patients with early-stage FL (stage I-II) from the SEER database between 2000 and 2015 were respectively analyzed. Primary sites were divided into intranodal and extranodal types. Intranodal primary sites included supradiaphragmatic lymph nodes (LN), subphrenic lymph nodes and Waldeyer's ring. Extranodal primary sites consisted of skin, gastrointestinal tract, duodenum, head and neck, other sites. Prognostic factors and overall survival (OS) in patients with different primary sites were analyzed. OS rate was evaluated using Kaplan-Meier method and survival difference between primary sites was compared with log-rank test. Inverse probability treatment weighting (IPTW) and multi-variable analysis were applied to adjust for confounding factors. Multivariate Cox regression analysis of influencing factors of OS was performed.Results:The median age was 63 years old, with the median follow-up time of 63 months. There was no difference in prognosis among the intranodal groups or between the intranodal and extranodal groups. The 10-year OS rates of the supradiaphragmatic lymph LN ( n=2146), subdiaphragmatic LN ( n=2811), and the Waldeyer's ring ( n=151) groups were 70.7%, 69.9% and 73.4%, respectively ( P=0.422 for infradiaphragmatic LN vs. supradiaphragmatic LN, P=1.000 for Waldeyer's ring vs. supradiaphragmatic LN), and 70.3% and 68.9% for intranodal ( n=5108) and extranodal ( n=2059), respectively. There was no significant difference in OS between the groups ( P=0.581) after IPTW adjustment. The most common primary sites in extranodal disease were skin, gastrointestinal tract, head and neck, and duodenum. The 10-year OS for skin, gastrointestinal tract, and cutaneous was 74.2%, 74.7%, and 87.3%, respectively, significantly higher than 55.6% for other sites (duodenum vs. others sites, gastrointestinal vs. others sites, skin vs. others sites: all P<0.001). Multivariate Cox regression analysis revealed that difference in OS was not significant among the intranodal groups or between the intranodal and extranodal groups. However, different extranodal primary site was an independent prognostic factor for OS. Conclusions:Early FL patients with supradiaphragmatic LN, subdiaphragmatic LN and Waldeyer's ring, and between the intranodal and extranodal primary sites obtain similar prognosis. However, early-stage FL patients with different extranodal primary sites have prognostic differences. The prognosis of primary skin, gastrointestinal tract and duodenum is significantly better than that of other extranodal primary sites.

Objective To investigate alterations in interhemispheric functional connectivity(FC)in the cerebral cortices connected via the corpus callosum in patients with Alzheimer's disease(AD),and to explore their relationships with cognitive function and activities of daily living.Methods Resting-state functional magnetic resonance imaging data were collected from 28 patients with Alzheimer's dementia(d-AD),47 patients with mild cognitive impairment(MCI),and 37 healthy controls(HC).Using a trancallosal tract template,32 pairs of homologous cortical brain regions directly connected to 32 subregions of the corpus callosum were selected as regions of interest for interhemispheric FC analysis.Further correlation analyses were performed between FC values in patient groups and their scores on the Montreal Cognitive Assessment-Basic(MoCA-B)Scale and the Activities of Daily Living(ADL)Scale.Results Compared with HC group,both MCI and d-AD groups exhibited hyperconnectivity(significantly increased FC)in interhemispheric non-homologous brain regions.Specifically,hyperconnectivity in the MCI group was scattered across the frontal,parietal,temporal,and occipital lobes,while in the d-AD group,it was concentrated within the precentral and postcentral gyri.Notably,hyperconnectivity involving the prefrontal and occipital lobes in the MCI group showed significant declines in the d-AD group.The interhemispheric homologous FC in the d-AD group reduced more significantly than the MCI group.Additionally,in the d-AD group,2 interhemispheric FC within the prefrontal lobe(between the bilateral orbital parts of the inferior frontal gyrus,and between the left medial frontal gyrus and the right middle frontal gyrus)were correlated with MoCA-B scores,and 2 FC(between the bilateral middle occipital gyri,and between the left inferior parietal lobule and the right middle frontal gyrus)were correlated with ADL scores.Conclusion MCI and d-AD exhibit distinct patterns of interhemispheric FC alterations,and the interhemispheric FC changes in AD patients are non-progressive.The close relationships between interhemispheric homologous/non-homologous FC and MoCA-B/ADL scores in d-AD patients provide an objective basis and reference for clinical neuromodulation.

Objective To explore function-structure covariant patterns in Alzheimer's disease(AD)and mild cognitive impairment(MCI),and to investigate their associations with cognitive function and activities of daily living.Methods three-way parallel group independent component analysis(three-way pGICA),was used to identify the covariant patterns of resting-state functional MRI temporal data,gray matter density maps,and fractional anisotropy(FA)maps,and the differences between different groups were compared.Furthermore,the associations of covariant patterns with the Montreal Cognitive Assessment-Basic(MoCA_B)Scale scores and Activities of Daily Living Scale scores were analyzed.Results The function-structure covariant patterns in AD and MCI were characterized by the enhanced negative functional connectivity between the left posterior salience network and the right default mode network,the decreased gray matter density in the bilateral dorsolateral prefrontal cortex,and the reduced FA values in the left superior corona radiata(correlations:P<0.001,FDR corrected).Compared with HC group,AD group showed significant abnormalities in all identified covariant patterns(P<0.01,FDR corrected),but MCI group only exhibited a significant decrease in gray matter density in the bilateral dorsolateral prefrontal cortex(P<0.05,FDR corrected).Additionally,AD group had significantly lower FA value in the left superior corona radiata than MCI group(P<0.05,FDR corrected).The loadings reflecting the degree of covariation were significantly correlated with the Activities of Daily Living Scale scores(P<0.05,FDR corrected)but not with MoCA_B Scale scores.Conclusion The function-structure covariant patterns in AD and MCI are consistent with the declines in activities of daily living.The multimodal fusion analysis(three-way pGICA)provides a novel approach to understand the brain damage mechanisms underlying the covariant evolution of MCI and AD.
