Objective To investigate the role of STK4-AS1 in regulating the proliferation,invasion,and migration of esophageal squamous cell carcinoma(ESCC)cells through the MYG1/Notch signaling pathway.Methods Quantitative real-time PCR(qRT-PCR)was used to detect the expression of STK4-AS1 in ESCC cells.MTS assay,wound healing and Transwell assay were conducted to explore the proliferation,migration,and invasion abilities in each group in Eca109 and Kyse150 cells.mRNA sequencing(mRNA-seq)was used to detect the down-stream target genes of STK4-AS1.KEGG functional enrichment analyses were used to predict the possible biological processes and signaling pathways.qRT-PCR and western blot were performed to identify mRNA expression of MYG1 and the key downstream transcription factors HES1,HES5,and HEY1 of the Notch signaling pathway,as well as the protein expression of NICD1.Co-transfection plasmids(for over-expressing STK4-AS1 and MYG1)were used to detect the mRNA expression of HES1,HES5,and HEY1 and the protein expression of NICD1 which acted as the key downstream transcription factors in the Notch signaling pathway,as well as the effects on the proliferation,migration,and invasion abilities of ESCC cells.Results The expression of STK4-AS1 was decreased in ESCC cell lines(P<0.01).Over-expression of STK4-AS1 inhibited the proliferation,migration and invasion abilities in Eca109 and Kyse150 cells(P<0.05).STK4-AS1 negatively regulated the expression of MYG1(P<0.01),and the expression of MYG1 was increased in ESCC cell lines(P<0.01).Over-expression of MYG1 could partially reverse the effect of STK4-AS1 on the malignant biological behavior of Eca109 and Kyse150 cells(P<0.05),as well as the mRNA expressions of HES1,HES5,and HEY1 and the protein expression of NICD1(P<0.05).Conclusion STK4-AS1 affects the malignant biological behaviors of ESCC through the MYG1/Notch signaling pathway.

OBJECTIVE To investigate the pharmacological efficacy and mechanism of action of Atractylenolide Ⅰ(Atr-Ⅰ)in inhibiting colorectal cancer.METHODS Among three active compounds of Atractylodes macrocephala,Atr-Ⅰ exhibited the highest anti-tumor potency by MTT assay.The optimal concentration of Atr-Ⅰ was determined.The effect of Atr-Ⅰ on LoVo cell prolifera-tion was assessed via a clonogenic assay,while its impact on apoptosis and cell cycle progression was evaluated using flow cytometry.The influence of Atr-Ⅰ on the migration and invasion of LoVo cell line was examined through wound healing and Transwell migration assays.Western blot analysis was performed to explore the effects and mechanisms of Atr-Ⅰ on proteins associated with mi-gration,proliferation,and epithelial-mesenchymal transition(EMT)in LoVo cells.The CT26 mouse subcutaneous tumor model was established,and histopathological analysis was conducted using hematoxylin-eosin(HE)staining.Western blot was also used to assess the effects of Atr-Ⅰ on EMT-related proteins in mouse tissues to elucidate underlying mechanisms.RESULTS Atr-Ⅰ significantly reduced colorectal cancer cell viability,with statistically significant differences between treatment and control groups(P<0.05,P<0.01).Atr-Ⅰ induced apoptosis in LoVo cells,with the treatment group showing significant differences compared to the control(P<0.05,P<0.01).Cell cycle analysis revealed that Atr-Ⅰ exerted anti-tumor effects by inducing G2/M phase arrest,with increased G2 phase cell numbers in the LoVo treatment group compared to the control(P<0.05).Wound healing and Transwell migration assays confirmed that Atr-Ⅰ significantly inhibited tumor cell migration and invasion(P<0.05,P<0.01).Western blot analysis demonstra-ted that Atr-Ⅰ specifically suppressed the expression of c-Myc and Bcl-2(P<0.05),as well as cell cycle-related proteins CDK1,Cyclin B1,and Cyclin D1(P<0.05),and angiogenesis-related proteins VEGF and MMP9(P<0.05).Additionally,Atr-Ⅰ down-regulated EMT-related protein N-cadherin and upregulated E-cadherin expression(P<0.05).It also reduced the expression of p-AKT and p-S6K1(P<0.05).CONCLUSION Atr-Ⅰ exhibits potent anti-tumor effects against colorectal cancer,potentially through modulation of the AKT/S6K1 signaling pathway.

Objective To investigate the diagnostic accuracy and clinical applicability of the Linknet-VGG16 deep learning algorithm for measuring the effective optical zone(EOZ)after corneal refractive surgery.Methods This single-center retrospective cohort study included 69 patients(69 eyes)who underwent femtosecond laser-assisted in situ kerato-mileusis(FS-LASIK)(34 eyes)or small incision lenticule extraction(SMILE)(35 eyes)at the Refractive Surgery Center of Affiliated Zhengzhou Aier Eye Hospital of Henan University from June 2023 to June 2024.Data from the right eyes of all patients were selected for statistical analysis.During the surgery,patients in the FS-LASIK group adopted the VisuMax fem-tosecond laser system combined with the Amaris 750S excimer laser system,while those in the SMILE group only used the VisuMax femtosecond laser system.A total of 276 Pentacam images were re-examined postoperatively.A Linknet segmenta-tion model based on the VGG16 encoder was constructed,and image normalization techniques were applied to accelerate model convergence.Model performance was assessed using accuracy,intersection over union(IoU),and the Dice coeffi-cient.The traditional EOZ measurement method based on corneal tangential curvature served as the reference standard.Bland-Altman analysis was conducted to evaluate consistency across all images and within each group,and the time effi-ciency of both methods was compared.Results Six representative medical image segmentation architectures(U-Net,U-Net++,DeepLabv3-ResNet50,DeepLabv3+-ResNet50,Unet-Densenet169,and Linknet-VGG16)were systematically evaluated.The Linknet-VGG16 model demonstrated superior performance over the other 5 models in pixel-level accuracy,IoU and Dice coefficient,which were 99.83％,99.48％and 99.74％,respectively.Although there was no significant differ-ence in accuracy and Dice coefficient between Linknet-VGG16 and U-Net models(whose accuracy was 99.82％and Dice coefficient was 99.72％),the inference speed of the U-Net model(62.46 ms)was 31.76％slower than that of the Linknet-VGG16 model(42.62 ms).The evaluation results of a clinically applicable comprehensive scoring model(weights:accura-cy 20％,IoU 20％,Dice coefficient 20％,speed 25％,model size 15％)showed that the Linknet-VGG16 model achieved a score of 88.01,surpassing other architectures(U-Net:86.29;DeepLabv3+-ResNet50:80.41;DeepLabv3-ResNet50:73.82;U-Net++:73.22;Unet-Densenet169:66.66).Bland-Altman analysis revealed that the mean difference of the 136 images in the FS-LASIK group was 0.01 mm[95％limits of agreement(LoA):-0.36 to 0.35 mm],with 96.3％of data points falling within the LoA.The mean difference of the 140 images in the SMILE group was-0.01 mm(95％LoA:-0.36 to 0.33 mum),with 95.7％of data points falling within the LoA.The mean difference of all 276 images was 0.00 mm(95％LoA:-0.36 to 0.34 mm),with 96.4％of data points falling within the LoA.These results indicated excellent consistency.The average measurement time per image using the traditional EOZ measurement method was 13.00 minutes,whereas the deep learning model required only 3.22 seconds.Conclusion The traditional EOZ measurement method based on corne-al tangential curvature exhibits good consistency with the fully automatic EOZ measurement method based on deep learning algorithms,achieving high image recognition accuracy.Additionally,the deep learning algorithm significantly reduces measurement time,compared with the traditional method based on corneal tangential curvature.

Objective:To analyze the survival outcomes and prognostic factors of patients with ovarian carcino-sarcoma(OCS)based on SEER database.Methods:The data of 1285 OCS patients from 2000 to 2018 in SEER database were retrospectively analyzed.Univariate and multivariate Cox proportional hazards models were used to evaluate the prognostic factors associated with overall survival(OS)and cancer specific survival(CSS).Kap-lan-Meier survival curve was drawn to evaluate the survival analysis of patients' prognosis after clinical treatment.Results:①The study cohort included a total of 1285 OCS patients,The mean age of these patients was 66.21±11.71 years.Most patients had already experienced regional(22.80％)or distant(72.22％)metastasis at the time of diagnosis.②Multivariate Cox regression revealed,SEER stage of regional or distant metastasis,no surger-y,no chemotherapy,and no lymphadenectomy were independent risk factors for both patient OS and CSS(HR＞1,P＜0.05).Age ≥67 years was an independent risk factor for OS(HR＞1,P＜0.05).Age ≥ 83 years was an in-dependent risk factors for CSS(HR＞1,P＜0.05).③Kaplan-Meier survival analysis showed that among surgical patients with adjacent tissue invasion or distant metastasis had significantly better overall survival rate after lymph node dissection than those without(P＜0.001);We didn't see the significantly different effects of lymphadenecto-my on patients with localized disease(P=0.266).Among all patients who underwent surgery,the overall survival rate of all patients who received adjuvant chemotherapy after surgery was significantly better than that of those who did not(P＜0.001).Conclusions:Prognosis of OCS patients is associated with age,SEER comprehensive stage,surgery status,chemotherapy status,lymphadenectomy status.Patients with OCS who underwent cytore-ductive surgery and adjuvant chemotherapy had a better prognosis.However,it is questionable whether lymph-adenectomy is necessary in OCS patients with very early stage.

ObjectiveTo explore effect of Xianlian Jiedu prescription on the recurrence of colorectal cancer （CRC） and investigate the related mechanisms. MethodsA postoperative recurrence model was established in 25 Balb/c mice by injecting CT26 cells subcutaneously into the armpit， followed by surgical removal of 99% of the subcutaneous tumor. The mice were randomly divided into model group， low-dose Xianlian Jiedu prescription （XLJDP-L） group （6.45 g·kg^-1·d^-1）， medium-dose Xianlian Jiedu prescription （XLJDP-M） group （12.9 g·kg^-1·d^-1）， high-dose Xianlian Jiedu prescription （XLJDP-H） group （25.8 g·kg^-1·d^-1）， and 5-fluorouracil （5-FU） group （1×10^-3 g·kg^-1·d^-1）. The mice were euthanized after 14 days of continuous intervention， and recurrent tumor tissue was harvested. Hematoxylin and eosin （HE） staining was used to observe pathological and morphological changes in the recurrent tumor tissue. Immunohistochemistry （IHC） was employed to assess the expression of proliferating cell nuclear antigen （Ki67）， vascular endothelial growth factor （VEGF）， and platelet-endothelial cell adhesion molecule （CD31） in recurrent tumor tissue. The Western blot was used to detect the protein expression levels of angiopoietin-2 （ANG-2）， VEGF， phosphorylated-protein kinase B （p-Akt）， protein kinase B （Akt）， phosphorylated-phosphatidylinositol 3-kinase （p-PI3K）， and phosphatidylinositol 3-kinase （PI3K） in recurrent tumor tissue. ResultsBefore treatment， there were no statistical differences in tumor volume， tumor weight， and body mass among the XLJDP-L， XLJDP-M， and XLJDP-H groups and the 5-FU group compared to the model group， indicating model stability. After treatment， compared with those in the model group， the tumor volume and tumor weight in the XLJDP-L， XLJDP-M， and XLJDP-H groups and the 5-FU group were significantly reduced （P<0.01）， showing dose dependency. Meanwhile， there were no significant differences in body weight among the XLJDP-L， XLJDP-M， and XLJDP-H groups and the 5-FU group compared to the model group. HE staining showed that compared with that in the model group， tumor tissue in the XLJDP-L， XLJDP-M， and XLJDP-H groups and the 5-FU group had loosely arranged cells， increased intercellular spaces， small and shriveled nuclei， light staining， fewer mitotic figures and atypical nuclei， and increased necrotic areas. IHC showed that compared with those of the model group， the positive rates of Ki67， VEGF， and CD31 in the recurrent tumor tissue of the XLJDP-L， XLJDP-M， and XLJDP-H groups and the 5-FU group were significantly reduced （P<0.01） in a dose-dependent manner. Western blot results showed that compared with those of the model group， the protein expression levels of ANG-2 and VEGF in the recurrent tumor tissue of the XLJDP-L， XLJDP-M， and XLJDP-H groups and the 5-FU group were significantly downregulated （P<0.05， P<0.01）， and the p-Akt/Akt and p-PI3K/PI3K ratios were significantly decreased in a dose-dependent manner （P<0.05， P<0.01）. ConclusionXianlian Jiedu prescription significantly inhibits the recurrence of CRC in mice after subcutaneous tumor surgery. The mechanism may involve regulating the PI3K/Akt pathway and downregulating key angiogenic proteins such as ANG-2， VEGF， and CD31.

Methods:From August 2011 to January 2013, 715 patients with CAG in a multicenter, randomized, double-blind, placebo-controlled trial were enrolled from 16 tertiary first-class hospitals across the country, including the First Affiliated Hospital of Air Force Medical University, Nanfang Hospital of Southern Medical University, the First Hospital of Jilin University, West China Hospital of Sichuan University, etc., there were 476 cases in the LTEVB 12C group and 239 cases in the placebo group. The patients of the LTEVB 12C group received LTEVB 12C, and the patients of placebo group received LTEVB 12C mimetic, all the medications were taken 3 capsules each time and 3 times a day after meals, and the treatment course of 2 groups were both 6 months. The efficacy evaluation criteria included the effective rate (a decrease of ≥1 in histopathological score compared with baseline after 6 months of treatment) and the reversal rate (a decrease of ≥ 2 in histopathological score compared with baseline after 6 months of treatment in the patients with moderate to severe CAG). The impact of lesion sites on the therapeutic effects of LTEVB 12C was analyzed by logistic regression analysis. The two-way unordered Cochran-Mantel-Haenszel chi-square test considering the center effect and Pearson chi-square test were used for statistical analysis. Results:The effective rates of chronic inflammation at the antrum greater curvature and corpus greater curvature (23.3%, 110/473 vs. 13.0%, 31/239; 20.3%, 96/472 vs. 12.6%, 30/239), the effective rates of atrophy at the antrum lesser curvature, antrum greater curvature, gastric angle, corpus lesser curvature, and the corpus greater curvature (27.0%, 118/437 vs. 15.7%, 34/216; 29.2%, 126/432 vs. 18.5%, 38/205; 27.8%, 121/435 vs. 16.7%, 36/216; 32.5%, 127/391 vs. 19.8%, 37/187; 33.0%, 119/361 vs. 21.8%, 39/179), and the effective rates of intestinal metaplasia at the antrum lesser curvature, antrum greater curvature, gastric angle, and the corpus lesser curvature (45.0%, 112/249 vs. 29.8%, 31/104; 53.8%, 86/160 vs. 33.9%, 21/62; 45.8%, 103/225 vs. 24.0%, 25/104; 51.9%, 83/160 vs. 28.3%, 17/60) of the LTEVB 12C group were all higher than those of the placebo group, and the differences were statistically significant ( χ2=10.76, 6.39, 9.69, 7.91, 11.05, 9.62, 8.57, 5.20, 7.11, 12.45, and 6.73; all P<0.05). The reversal rates of chronic inflammation at the corpus lesser curvature and corpus greater curvature (5.2%, 12/231 vs. 0, 0/123; 4.7%, 8/170 vs. 0, 0/88), the reversal rates of atrophy at the antrum lesser curvature, antrum greater curvature, corpus lesser curvature, and the corpus greater curvature (6.8%, 22/323 vs. 1.3%, 2/151; 9.2%, 29/315 vs. 1.4%, 2/144; 14.2%, 38/267 vs. 2.5%, 3/121; 20.8%, 35/168 vs. 5.8%, 4/69), and the reversal rates of intestinal metaplasia at the antrum lesser curvature, antrum greater curvature, gastric angle, and the corpus lesser curvature (29.8%, 39/131 vs. 9.1%, 4/44; 41.0%, 32/78 vs. 12.5%, 3/24; 33.3%, 44/132 vs. 4.8%, 3/63; 50.0%, 37/74 vs. 8.7%, 2/23) of the LTEVB 12C group were all higher than those of the placebo group, and the differences were statistically significant ( χ2=6.58, 5.12, 5.60, 8.61, 11.43, 6.59, 7.30, 4.95, 15.92, 7.62; all P<0.05). There were no statistically significant differences in the effective rates and reversal rates of active inflammation at different locations between the LTEVB 12C group and the placebo group (all P>0.05). The results of logistic regression analysis (taking the antrum lesser curvature as the reference) further confirmed that the reversal rates of chronic inflammation ( OR=0.22, 95% confidence interval (95% CI): 0.07 to 0.67; OR=0.24, 95% CI: 0.07 to 0.80), atrophy ( OR=0.28, 95% CI: 0.16 to 0.49; OR=0.28, 95% CI: 0.16 to 0.49), and intestinal metaplasia ( OR=0.42, 95% CI: 0.24 to 0.77; OR=0.20, 95% CI: 0.08 to 0.52) at the corpus lesser curvature and corpus greater curvature were all higher than those at the antrum lesser curvature, and the differences were statistically significant (all P<0.05). There were no statistically siginificant differences in the reversal rates of the aforementioned pathological features between the antrum greater curvature, gastric angle, and the antrum lesser curvature (all P>0.05). Conclusion:LTEVB 12C can achieve good efficacy in the treatment of CAG, and the chronic inflammation, atrophy, and intestinal metaplasia at multiple locations are improved, especially at the corpus lesser curvature and the corpus greater curvature.

Objective:To analyze the efficacies of unilateral biportal endoscopy(UBE)and percutaneous endoscopic transforaminal discectomy(PETD)in treatment of lumbar disc herniation(LDH),and to explore the optimal selection of minimally invasive surgical approaches for the The LDH patients.Methods:A retrospective analysis was performed on the clinical data of 64 LDH patients who underwent surgery at Liwan Central Hospital of Guangzhou City in Guangdong Province,between January 2020 and June 2024.The surgical approaches were determined through physician-patient communication,and the patients were divided into UBE group(n=30)and PETD group(n=34).The materials of patients were recorded including gender,age,body mass index(BMI),percentages of affected segments,course of disease,duration of hospitalization,operation duration,intraoperative blood loss,numbers of intraoperative fluoroscopy,total incision length,and time to full weight-bearing(WB).The therapeutic outcomes were evaluated using Oswestry disability index(ODI),Visual Analog Scale(VAS)scores for low back pain and leg pain,MacNab criteria,and spinal canal areas at the affected segment.the postoperative complications of the patients in two groups were analyzed.Results:There were no statistically significant differences in age,gender composition ratio,BMI,course of disease,and percentages of affected segments of the patients between UBE group and PETD group(P＞0.05).Compared with PETD group,the intraoperative blood loss,total incision length,and time to full WB of the patients in UBE group were significantly increase(P＜0.01),while the number of intraoperative fluoroscopy time was decreased(P＜0.01).Compared with pre-operation,the ODI scores and VAS scores for low back and leg pain of the patients at final follow-up in both groups were decreased(P＜0.01),and the spinal canal areas at the affected segments of the patients were increased(P＜0.01).At final follow-up,compared with PETD group,the ODI score and VAS scores for low back and leg pain of patients in UBE group were decreased(P＜0.01),while the spinal canal areas at the affected segments of the patients was increased(P＜0.01).According to MacNab criteria,the percentages of excellent and good had no significant difference between two groups(P＞0.05).The incidence of complication showed no statistical difference between two groups(P＞0.05).Conclusion:Both UBE and PETD yield satisfactory outcomes in the treatment of single-segment LDH.PETD is less invasive and permits earlier time to full WB,whereas UBE provides more extensive decompression and superior long-term efficacy.The surgical approach selection should be individualized based on specific factors in the clinic.
