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.

Autoimmune hepatitis （AIH） is an immune-mediated chronic liver inflammatory disease with unknown pathogenesis， and intestinal barrier dysfunction is considered an important factor. Meanwhile， there are sex and age differences in the incidence rate of AIH， suggesting that hormone may be involved in regulation. On this basis， this article focuses on the association between estrogen， intestinal barrier， and immune homeostasis， systematically reviews the evidence that estrogen deficiency disrupts intestinal barrier homeostasis， and further summarizes the potential mechanism of estrogen in regulating the development and progression of AIH via intestinal barrier.

Myopic traction maculopathy(MTM)is a common vision-threatening complication in patients with high myopia. With the global increase in high myopia, the prevalence of MTM has been rising worldwide, leading to a growing burden of disease, economic costs,and social impact. The emergence and development of optical coherence tomography(OCT)have provided robust technical support for the staging of MTM. Based on the evolving understanding of its pathological mechanisms and natural course, various staging systems have been proposed and applied in clinical practice, offering crucial guidance for the personalized management of MTM patients. Additionally, innovations and refinements in surgical techniques and materials, such as pars plana vitrectomy(PPV), posterior scleral reinforcement, and macular buckling(MB), have expanded the therapeutic options for MTM. This article systematically reviews the staging systems and treatment strategies for MTM, focusing on the role of OCT-based staging in guiding individualized treatment plans. It also summarizes the current evidence on the efficacy and safety of existing and emerging surgical approaches, including PPV, MB, and their combined procedures. The review further proposes that future research should focus on developing predictive models integrating multimodal data to clarify surgical timing and indications, as well as conducting large-scale, multicenter randomized controlled trials to explore the selection of PPV, MB, or combined surgeries. The review aims to discuss personalized treatment for MTM, providing theoretical foundations and practical directions for optimizing clinical management and improving patient prognosis for MTM patients.

Objective : To explore the expression profile of core 1 β1,3-galactosyltransferase 1(C1GALT1) in glioblastoma(GBM) and to elucidate its impact on the initiation and progression of GBM. Methods : The expression levels and prognostic significance of C1GALT1 in GBM were analyzed using the GEPIA and CGGA databases. Two representative glioblastoma cells(U251 and LN18) were selected to construct C1GALT1-knockdown cell lines and performed in vitro experiments. The Cell Counting Kit-8(CCK-8) and Transwell assays were employed to evaluate the impact of C1GALT1 on proliferation, migration and invasion of GBM cells. Transcriptome data were analyzed to identify potential signaling pathways. Senescence β-Galactosidase Staining Kit was used to detect β-galactosidase activity. Results : nalysis of GEPIA and CGGA databases revealed that C1GALT1 was significantly upregulated in GBM tissues compared to adjacent non-cancerous tissues (P < 0. 05) , and its high expression was associated with poor prognosis of patients (P < 0. 000 1) . The CCK-8 experiment demonstrated a significant reduction in prolifera- tion rate following C1GALT1 knockdown (P < 0. 05) . Transwell assay showed that cell migration and invasion de- creased after C1GALT1 was knocked down ( P < 0. 001) . Transcriptome sequencing and senescence β-galactosi- dase staining showed that C1GALT1 was involved in the cellular senescence signaling pathway , and the activity of β-galactosidase associated with cellular senescence significantly increased after C1GALT1 was knocked down(P < 0. 05) . Conclusion C1GALT1 is overexpressed in GBM tissues and may promote the proliferation , migration and invasion of GBM cells by inhibiting cellular senescence .

Objective:To explore the assessment value of ultrasound scoring system combined with shear wave elastography(SWE)on curative effect of IgG4-related submandibular and lacrimal gland inflammation.Methods:This study was a prospective cohort study.A total of 103 patients with IgG4-related submandibular and/or lacrimal gland inflammation who admitted to the Department of Rheumatology and Immunology of Beijing Friendship Hospital,Capital Medical University from September 2022 to December 2024 were consecutively included.They were divided into an effective group(45 cases)and a non-effective group(58 cases)based on the curative effect.All patients were assessed by conventional ultrasound and SWE before and after treatment.Logistic regression analysis was used to determine the independent influencing factors of assessing the curative effect,and then,a receiver operating characteristic(ROC)curve and nomograms were drawn.Results:There were no statistically significant differences in gender and age between the effective group and the non-effective group(P>0.05).The difference between the submandibular and lacrimal gland score,change rate of score,difference of mean Young's modulus(Emean),Emean change rate,difference of maximum value of Young's modulus(Emax),and Emax change rate in the effective group were all higher than those in the non-effective group,and the differences were statistically significant(Z=-7.916,-7.680,-6.767,-6.722,-6.360,-5.957,P<0.05),respectively.The difference between the submandibular and lacrimal gland score(OR=2.90,P<0.001)and the Emax difference(OR=1.18,P<0.05)had diagnostic value for assessing the curative effectiveness.The area under curve(AUC)value,sensitivity,specificity and accuracy of the difference between submandibular and lacrimal gland score were respectively 0.945,88.9%,94.8%and 87.4%in assessing the curative effectiveness.The above indicators of Emax difference were respectively 0.866,86.7%,70.7%and 77.7%in assessing the curative effectiveness.The above indicators of the combination of them were respectively 0.976,93.3%,94.8%and 94.2%.Conclusion:The combination of the conventional ultrasound scoring system and SWE has higher diagnostic value in assessing the curative effect of IgG4-related submandibular and lacrimal gland inflammation.The combined application can significantly improve the accuracy and provide reliable imaging reference for clinical practice.

Objective To investigate the cardiac protective effect of Taohong Tongluo granules on coronary microvascular dysfunction(CMD)rats.Methods SD rats were randomly assigned to sham-operated group,CMD group,nicorandil group(5 mg/kg),or Taohong Tongluo granule group(50 mg/kg).Animals were administered corresponding drugs for 7 d according to the grouping,and the CMD model was prepared 2 h after the last administration.The rat CMD model was induced by injecting embolization microspheres(diameter 40-120 μm,approximately 1 000 microspheres)into the left ventricular cavity.Twenty-four hours after modeling,echocardiography was performed to measure the left ventricular ejection fraction(EF),fractional shortening(FS),and end-diastolic volume(EDV).The damaged myocardial area was assessed by 2,3,5-triphenyltetrazolium chloride(TTC)staining.Myocardial morphological changes were observed by hematoxylin-eosin(H-E)staining.The protein expression levels of NOD-like receptor family pyrin domain containing protein 3(NLRP3),apoptosis-associated speck-like protein(ASC),and cysteine aspartic acid specific protease(caspase)-1 in rat myocardial tissue were detected by immunohistochemical staining and Western blotting.Results Echocardiography showed that the EF and FS values in the Taohong Tongluo granule group,CMD group,and nicorandil group were significantly lower than those in the sham-operated group(all P＜0.001).The EF and FS values in the Taohong Tongluo granule group and nicorandil group were significantly higher than those in the CMD group(all P＜0.01).However,there were no significant differences in EDV among the groups(all P＞0.05).H-E staining showed no abnormalities in the myocardium in the sham-operated group.The CMD group exhibited microsphere embolism in the myocardium,myocardial cell dissolution and rupture,and inflammatory infiltration.The lesions in the nicorandil group and the Taohong Tongluo granule group were relatively milder,and the number of thrombi in both groups was lower than that in the CMD group(both P＜0.01).The results of TTC staining indicated that the areas of damaged myocardial regions in both the nicorandil group and the Taohong Tongluo granule group were smaller than that in the CMD group(P＜0.05 or P＜0.01).Moreover,the area in the Taohong Tongluo granule group was smaller than that in the nicorandil group(P＜0.05).The results of immunohistochemical staining showed that in the CMD model,the expression of ASC and caspase-1 proteins,as well as the number of positive cells for these proteins,was increased and was distributed in myocardial and interstitial cells.The numbers of ASC and caspase-1 positive cells in the Taohong Tongluo granule group were lower than that in the CMD group(both P＜0.01).The Western blotting showed that the expression levels of NLRP3,ASC,and caspase-1 proteins in the Taohong Tongluo granule group were all lower than those in the CMD group(all P＜0.05).Conclusion Taohong Tongluo granules can improve cardiac function,ameliorate hemodynamic parameters,and reduce myocardial infarction area in rats with CMD induced by microsphere embolism.The mechanism is related to the inhibition of myocardial inflammasome activation,thereby attenuating the myocardial injuries.

Bombesin receptor subtype-3 (BRS3) is an orphan G protein-coupled receptor (GPCR) that plays critical roles in energy homeostasis, glucose metabolism, and insulin secretion. Recent structural studies have elucidated BRS3 signaling mechanisms using synthetic ligands, including BA1 and MK-5046. However, the molecular basis of BRS3 activation by bioactive natural compounds and their derivatives, particularly those derived from traditional Chinese medicine, remains unclear. Here, we present high-resolution cryogenic electron microscopy (cryo-EM) structures of the human BRS3-G_q complex in both unliganded and active states bound by two herb-derived compounds (DSO-5a and oridonin), at resolutions of 2.9, 2.8, and 2.9 Å, respectively. These structures display distinct ligand recognition patterns between DSO-5a and oridonin. Although both compounds bind to the orthosteric pocket, they differentially engage the interaction network of BRS3, as demonstrated by mutagenesis studies assessing calcium mobilization and inositol phosphate 1 (IP1) accumulation. These findings enhance our understanding of BRS3 activation and provide valuable insights into the development of small-molecule BRS3 modulators with therapeutic potential.

Glioblastoma (GBM) is a highly aggressive primary brain tumor characterized by poor prognosis. Conventional chemo-radiotherapy demonstrates limited therapeutic efficacy and is often accompanied by significant side effects, largely due to factors such as drug resistance, radiation resistance, the presence of the blood-brain barrier (BBB), and the activation of DNA damage repair mechanisms. There is a pressing need to enhance treatment efficacy, with BRD4 identified as a promising target for increasing GBM sensitivity to therapy. Lacking small molecule inhibitors, BRD4 can be degraded using PROteolysis Targeting Chimera (PROTAC), thereby inhibiting DNA damage repair. To deliver PROTAC, SIAIS171142 (SIS) effectively, we designed a responsive nanocapsule, MPL_(SS)P@SIS, featuring GBM-targeting and GSH-responsive drug release. Modified with 1-methyl-l-tryptophan (MLT), nanocapsules facilitate targeted delivery of SIS, downregulating BRD4 and sensitizing GBM cells to radiotherapy and chemotherapy. After intravenous administration, MPL_(SS)P@SIS selectively accumulates in tumor tissue, enhancing the effects of radiotherapy and temozolomide (TMZ) by increasing DNA damage and oxidative stress. GSH activates the nanocapsules, triggering BRD4 degradation and hindering DNA repair. In mouse models, the nanosensitizer, combined with TMZ and X-ray irradiation, efficiently inhibited the growth of GBM. These findings demonstrate a novel PROTAC-based sensitization strategy targeting BRD4, offering a promising approach for effective GBM therapy.
