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.

Appropriate medicines can be selected clinically according to actual conditions and patients’ characteristics.

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 investigate the effect of miR-129-1-3p on the osteogenic differentiation of human bone marrow mesenchymal stem cells(hBMSCs)and its potential mechanism.Methods Negative control group,the miR-129-1-3p mimic group,the miR-129-1-3p inhibitor group and the corresponding negative control were constructed and transfected into hBMSCs.The formation of calcium-mineralized nodules was observed by alkaline phosphatase staining and alizarin red S staining.The expression levels of miR-129-1-3p and osteogenic differentiation markers were detected by qRT-PCR.Western blot detected the protein expressions of bone mor-phogenetic protein 2(BMP2),SMAD1 and p-SMAD1.Results After transfection,the expression level of miR-129-1-3p in mimic group was significantly increased(P＜0.05),the number of mineralized nodules was significantly decreased,and the expression levels ofBMP2,Runt-related transcription factor 2(RUNX2),osteocalcin(OCN)mRNA were significantly down-regulated(P＜0.05).BMP2 and p-SMAD1 protein were also significantly down-regulated(P＜0.05)compared with Mimic-NC group.The expression levels of BMP2,RUNX2,OCN mRNA were significantly up-regulated in inhibitor group(P＜0.05)compared with Inhibitor-NC group.BMP2 and p-SMAD1 protein were significantly up-regulated in inhibitor group(P＜0.05).Conclusion miR-129-1-3p can inhibit the osteo-genic differentiation of human bone marrow mesenchymal stem cells by suppressing BMP2/SMAD1 signaling pathway.

Objective·To investigate the predictive value of the geriatric nutritional risk index(GNRI)for the occurrence of lung infection in hospitalized elderly patients with type 2 diabetes mellitus(T2DM).Methods·Elderly T2DM patients who were admitted to the Geriatric Department of Shanghai Tongren Hospital between June 2022 and June 2024 were retrospectively and consecutively enrolled.They were divided into infected and non-infected groups according to whether lung infection occurred during hospitalization.Baseline data(gender,age,height,weight,duration of diabetes,comorbidities,etc.)were collected and GNRI was calculated.A multivariate Logistic regression model was used to screen the independent risk factors for pulmonary infections,and the predictive value of GNRI for pulmonary infections in T2DM patients was analysed using receiver operating characteristic(ROC)curves.Results·A total of 264 elderly T2DM patients were enrolled,among whom 154 developed pulmonary infections.Significant differences were observed between the infected and non-infected groups in GNRI,albumin,leukocyte count,neutrophil ratio,lymphocyte ratio,glycated hemoglobin,fasting glucose,interleukin-6,C-reactive protein,and procalcitonin levels(P<0.05).Multivariate Logistic regression analysis showed that a lower GNRI was an independent risk factor for lung infection(OR=0.798,95%CI 0.712?0.894;P<0.001).Correlation analysis showed that GNRI was negatively correlated with C-reactive protein and calcitoninogen.ROC curve analysis showed that GNRI predicted pulmonary infection with an area under the curve of 0.828,a sensitivity of 77.9%,and a specificity of 76.6%.Conclusion·A lower GNRI is an independent risk factor for pulmonary infections in elderly T2DM patients,and also has a good predictive value for the occurrence of pulmonary infections.

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.

Objective To analyze the levels of serum solute carrier family 7 member 11(SLC7A11)and platelet-derived growth factor BB(PDGFBB)in children with bronchial asthma and their correlations with disease severity.Methods A total of 80 children with acute asthma were en-rolled in acute asthma group,and divided into severe asthma group(40 cases)and mild asthma group(40 cases)according to severity of the disease.Additionally,80 children with asthma in re-mission during the same period were enrolled in remission group,and 80 healthy children undergoing physical examination during the same period were enrolled in control group.Enzyme-linked immu-nosorbent assay(ELISA)was used to detect the levels of serum SLC7A11 and PDGFBB in children from each group.Pearson correlation analysis was conducted to assess the correlation between serum levels of SLC7A11 and PDGFBB and lung function indicators[peak expiratory flow(PEF)and forced expiratory volume in one second as percentage of predicted(FEV1％pred)]in asthmatic children.Multivariate Logistic regression analysis was performed to explore the relationships ofn ser-um levels of SLC7A11 and PDGFBB with disease severity in asthmatic children.Receiver operating characteristic(ROC)curves were plotted to evaluate the diagnostic efficacy of serum SLC7A11 and PDGFBB levels for severe asthma.Results The serum SLC7A11 levels and PEF,FEV1％pred in the acute asthma group were lower than those in the remission group and control group,while the PDGFBB levels were higher than those in the remission group and control group(P＜0.05).The serum SLC7A11 levels and PEF,FEV1％pred in the remission group were lower than those in the con-trol group,while the PDGFBB levels were higher than those in the control group(P＜0.05).The ser-um SLC7A11 levels in asthmatic children were positively correlated with PEF and FEV1％pred(P＜0.05),while the serum PDGFBB levels were negatively correlated with PEF and FEV1％pred(P＜0.05).The serum SLC7A11 levels and PEF,FEV1％pred in the severe asthma group were lower than those in the mild asthma group,while the PDGFBB levels were higher than those in the mild asthma group(P＜0.05).High PEF,high FEV1％pred,and high SLC7A11 were independent protective factors for severe asthma(P＜0.05),while high PDGFBB was an independent risk factor(P＜0.05).The area under the ROC curve for the combined diagnosis of severe asthma using ser-um SLC7A11 and PDGFBB levels was 0.851,significantly larger than the areas under the ROC curves for the individual diagnosis using SLC7A11(0.790)and PDGFBB(0.785)alone(P＜0.05).Conclusion Decreased serum SLC7A11 levels and increased serum PDGFBB levels in asthmatic children are closely related to decreased lung function and increased disease severity.The combined detection of these two biomarkers has high diagnostic value for severe asthma.

Eight new diterpenoids, Isodons A-H (1-8), comprising seco-abietane and abietane-type structures, together with 13 known analogues (9-21), were isolated from Isodon lophanthoides (Buch.-Ham. ex D. Don) Hara. The compounds (+)-3/(-)-3, (+)-4/(-)-4, and (+)-5/(-)-5 were identified as three enantiomeric pairs. The planar structures and absolute configurations of 1-8 were determined through high-resolution electrospray ionization mass spectrometry (HR-ESI-MS), 1D & 2D nuclear magnetic resonance (NMR) spectroscopy, electronic circular dichroism (ECD) calculations, and X-ray diffraction crystallography. A cholesterol 7α-hydroxylase (Cyp7a1) luciferase reporter assay revealed significant anti-cholestatic activities for compounds 1, (+)-4, 6, 7, 12-14, and 16. Additionally, compound 6 demonstrated anti-cholestatic effects through the farnesoid X receptor (FXR)-associated signaling pathways in vitro and in vivo. These findings suggest potential applications for I. Lophanthoides in pharmaceutical development.

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 .
