Endometriosis （EMT） is a common disease with frequent occurrence and difficult to be cured in modern clinical practice of obstetrics and gynaecology. It is characterized by progressively worsening dysmenorrhoea， pelvic mass， and infertility. The incidence of EMT is growing and increasingly younger patients are diagnosed with this disease， which poses a serious threat to the reproductive and psychological health of women of childbearing age and adolescent females. However， the pathogenesis of EMT is still not completely clear， and the disease has a long course. Therefore， developing new therapies is an urgent clinical problem to be solved. Great progress has been achieved in the treatment of EMT with traditional Chinese medicine （TCM）， while the underlying mechanism remains in exploration. Programmed cell death （PCD） is a cell death mode mediated by a variety of bio-molecules with specific signaling cascades. The known PCD processes include apoptosis， pyroptosis， autophagy， ferroptosis， and cuproptosis， which all play a pivotal role in the development of EMT. Researchers have made achievements in the treatment of EMT with TCM， which regulates PCD via multiple pathways， routes， targets， and mechanisms. However， the progress in the regulation of PCD in the treatment of EMT with TCM remains to be reviewed. This paper reviews the research progress in the treatment of EMT with TCM from five PCD processes （apoptosis， pyroptosis， autophagy， ferroptosis， and cuproptosis）， with the aim of providing a theoretical basis for the clinical prevention and treatment of EMT.

Objective: The CT/MRI Liver Imaging Reporting and Data System (LI-RADS) demonstrates high specificity with relatively limited sensitivity for diagnosing hepatocellular carcinoma (HCC) in high-risk patients. This study aimed to explore the possibility of improving sensitivity by combining CT/MRI LI-RADS v2018 with second-line contrast-enhanced ultrasound (CEUS) LI-RADS v2017 using sulfur hexafluoride (SHF) or perfluorobutane (PFB). Materials and Methods: This retrospective analysis of prospectively collected multicenter data included high-risk patients with treatment-naive hepatic observations. The reference standard was pathological confirmation or a composite reference standard (only for benign lesions). Each participant underwent concurrent CT/MRI, SHF-enhanced US, and PFB-enhanced US examinations. The diagnostic performances for HCC of CT/MRI LI-RADS alone and three combination strategies (combining CT/ MRI LI-RADS with either LI-RADS SHF, LI-RADS PFB, or a modified algorithm incorporating the Kupffer-phase findings for PFB [modified PFB]) were evaluated. For the three combination strategies, apart from the CT/MRI LR-5 criteria, HCC was diagnosed if CT/MRI LR-3 or LR-4 observations met the LR-5 criteria using LI-RADS SHF, LI-RADS PFB, or modified PFB. Results: In total, 281 participants (237 males; mean age, 55 ± 11 years) with 306 observations (227 HCCs, 40 non-HCC malignancies, and 39 benign lesions) were included. Using LI-RADS SHF, LI-RADS PFB, and modified PFB, 20, 23, and 31 CT/MRI LR-3/4 observations, respectively, were reclassified as LR-5, and all were pathologically confirmed as HCCs. Compared to CT/MRI LI-RADS alone (74%, 95% confidence interval [CI]: 68%–79%), the three combination strategies combining CT/MRI LI-RADS with either LI-RADS SHF, LI-RADS PFB, or modified PFB increased sensitivity (83% [95% CI: 77%–87%], 84% [95% CI: 79%–89%], 88% [95% CI: 83%–92%], respectively; all P < 0.001), while maintaining the specificity at 92% (95% CI: 84%–97%). Conclusion The combination of CT/MRI LI-RADS with second-line CEUS using SHF or PFB improved the sensitivity of HCC diagnosis without compromising specificity.

OBJECTIVE To evaluate the efficacy， safety and economics of the centrally procured generic versus original esomeprazole in the treatment of acute non-variceal upper gastrointestinal bleeding （ANVUGIB）. METHODS A retrospective collection of real-world clinical data was conducted for ANVUGIB patients who received treatment at Shenzhen People’s Hospital and University of Hong Kong-Shenzhen Hospital from January 2018 to March 2024. Patients were divided into imported original drug group （original drug group， 221 cases） and centrally procured generic drug group （generic drug group， 75 cases） according to the types of drug used. Propensity score matching （PSM） was performed at a ratio of 3∶1 to compare the clinical efficacy， safety and economics between the two groups. RESULTS Totally 241 patients were included after PSM， with 170 in the original drug group and 71 in the generic drug group. There were no significant differences between the two groups in terms of rebleeding rate， rate of second endoscopic intervention， blood transfusion rate， length of hospital stay， mortality due to gastrointestinal bleeding， 30-day readmission due to rebleeding， and overall survival rate （P＞0.05）. The incidence of adverse events among all patients in both groups also showed no statistically significant difference （P＞0.05）； furthermore， the adverse events reported by the respective hospitals to the National Center for ADR Monitoring were comparable between the two groups. After PSM， the median total drug cost and high-dose esomeprazole cost in the generic drug group were significantly lower than those in the original drug group， while the median nursing fee and bed fee were significantly higher than those in the original drug group （P＜0.05）. There was no statistically significant difference between the two groups in terms of median total hospitalization expenses， total treatment costs， laboratory fees， examination fees， material costs， or consultation fees （P＞0.05）. CONCLUSIONS The clinical efficacy and safety of centrally procured generic esomeprazole in the treatment of ANVUGIB are comparable to those of the original drug， and it is more economical.

[摘 要] 目的：探讨2',4'-二羟基查尔酮（D2）通过调控miR-7-5p诱导自噬，抑制结直肠癌细胞增殖、迁移及上皮间质转化（EMT）的分子机制。方法：选取结直肠癌细胞系HCT-15、SW620为研究对象，分别用不同浓度（0、12.5、25、50 µmol/L）的D2处理细胞，采用MTT法和平板克隆实验检测细胞增殖活力及克隆形成能力，划痕愈合实验及Transwell实验评估细胞迁移能力，WB法检测EMT相关蛋白、自噬相关蛋白及PI3K/AKT/mTOR信号通路蛋白的表达情况，免疫荧光染色法观察自噬小体的形成。基于TCGA数据库分析miR-7-5p在结直肠癌中的表达水平，并借助KEGG富集分析探究miR-7-5p与结直肠癌的关联。运用RT-qPCR检测miR-7-5p的表达量，同时采用慢病毒转染技术构建miR-7-5p稳定敲低或过表达的细胞系。结果：D2抑制结直肠癌细胞的增殖、迁移及EMT进程（P < 0.05或P < 0.01）。TCGA数据库分析及KEGG富集分析显示，miR-7-5p在结直肠癌中呈低表达，且与结直肠癌的发生有密切关联。12.5、25、50 µmol/L D2处理均可上调HCT-15、SW620细胞miR-7-5p的表达水平（均P < 0.01）。25 µmol/L D2处理组HCT-15、SW620细胞中 LC3、p-ULK1等自噬相关蛋白表达增加，而PI3K/AKT/mTOR信号通路受到抑制（均P < 0.05），细胞内自噬小体数量增加（均P < 0.01）；与D2单独处理组相比，经 D2处理的miR-7-5p敲减细胞中LC3、p-ULK表达量有所下降（P < 0.05或P < 0.01）。结论：D2通过调控miR-7-5p诱导自噬，抑制结直肠癌细胞的增殖、迁移及EMT进程，其机制可能与抑制PI3K/AKT/mTOR信号通路有关。

OBJECTIVE: To observe the effect of electroacupuncture at "Sishencong" (EX-HN1) and "Fengchi" (GB20) on hippocampal neuronal ferritinophagy mediated by the nuclear receptor coactivator 4 (NCOA4)/ferritin heavy chain 1 (FTH1) signaling pathway in vascular dementia (VD) rats, and to explore the potential mechanisms of electroacupuncture for VD. METHODS: A total of 60 male rats of SPF grade were randomly divided into a blank group (12 rats), a sham surgery group (12 rats) and a modeling group (36 rats). In the modeling group, the modified 4-vessel occlusion method was used to establish the VD model. The 24 successfully modeled rats were randomly divided into a model group and an electroacupuncture group, with 12 rats in each group. In the electroacupuncture group, electroacupuncture was applied at left and right "Sishencong" (EX-HN1), and bilateral "Fengchi" (GB20), with continuous wave, in frequency of 2 Hz and current intensity of 1 mA, 30 min a time, once daily for 21 consecutive days. The learning and memory abilities were assessed using the Morris water maze test before modeling, after modeling and after intervention, as well as the novel object recognition test after intervention. After intervention, the neuronal morphology in the hippocampus was observed by Nissl staining; the iron deposition was observed by Prussian blue staining; the reactive oxygen species (ROS) level was detected by dihydroethidium (DHE) fluorescence staining; the levels of iron, malondialdehyde (MDA) and superoxide dismutase (SOD) in the hippocampal tissue were measured by the colorimetric assay, TBA method, and WST-1 method, respectively; the positive expression of NCOA4, FTH1 and glutathione peroxidase 4 (GPX4) was detected by immunohistochemistry; the protein expression of NCOA4, FTH1, GPX4, and the ratio of microtubule-associated protein 1 light chain 3B (LC3B) Ⅱ/Ⅰ in the hippocampus were detected by Western blot. RESULTS: Compared with the sham surgery group, in the model group, the escape latency was prolonged, and the number of platform crossings reduced (P<0.01), the recognition index (RI) was decreased (P<0.01); the hippocampal neurons displayed a blurred laminar structure, disorganized cellular arrangement, and the number of Nissl bodies was decreased (P<0.01); the percentage of iron deposition area in the hippocampus was increased (P<0.01); in the hippocampus, the levels of ROS, iron, MDA, and the protein expression of NCOA4, as well as the LC3B Ⅱ/Ⅰ ratio were increased (P<0.01), the SOD level, and the protein expression of FTH1 and GPX4 were decreased (P<0.01). Compared with the model group, in the electroacupuncture group, the escape latency was shortened and the number of platform crossings was increased (P<0.01), the RI was increased (P<0.01); the hippocampal neurons exhibited more regular morphology, better-organized cellular structure, and the number of Nissl bodies was increased (P<0.05); the percentage of iron deposition area in the hippocampus reduced (P<0.01); in the hippocampus, the levels of ROS, iron, MDA, and the protein expression of NCOA4, as well as the LC3B Ⅱ/Ⅰ ratio were decreased (P<0.01, P<0.05), the SOD level, and the protein expression of FTH1 and GPX4 were increased (P<0.01). CONCLUSION Electroacupuncture at "Sishencong" (EX-HN1) and "Fengchi" (GB20) can improve learning and memory abilities in VD rats, and its mechanism may be associated with the regulation of the hippocampal NCOA4/FTH1 signaling pathway, inhibition of ferritinophagy, and alleviation of oxidative stress damage.
