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 evaluate the correlation between ultrasound parameters of internal carotid artery blood flow and regional cerebral oxygen saturation (rScO 2) in elderly patients undergoing coronary artery bypass grafting (CABG) under cardiopulmonary bypass (CPB). Methods:Sixty-four elderly patients undergoing elective CABG under CPB, aged 60-80 yr, regardless of gender, with body mass index of 18.1-28.9 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, with New York Heart Association class Ⅱ or Ⅲ, with left ventricular ejection fraction≥50%, were selected. The rScO 2 and ultrasonic parameters of internal carotid artery including peak systolic velocity (PSV-ICA), end-diastolic velocity (EDV-ICA), diameter (D-ICA) and blood flow volume (Q-ICA) were recorded before anesthesia induction (T 0), at surgical skin incision (T 1), at 30 and 60 min of CPB (mean value was calculated, T 2), and at 30 and 60 min after termination of CPB (mean value was calculated, T 3). The ratio of unilateral internal carotid artery blood flow to cardiac output (Q/CO) was calculated. The receiver operating characteristic curve was used to analyze the accuracy of ultrasound parameters of internal carotid artery blood flow in predicting rScO 2 < 60%. Results:PSV-ICA was positively correlated with rScO 2 at T 0, T 1 and T 3 ( P<0.05), but no correlation was found between PSV-ICA and rScO 2 at T 2 ( P>0.05). There was no correlation between EDV-ICA and rScO 2 at each time point ( P>0.05). Q-ICA was positively correlated with rScO 2 at each time point ( P<0.05). Q/CO was not correlated with rScO 2 at T 1 ( P>0.05), but Q/CO was positively correlated with rScO 2 at T 2 and T 3 ( P<0.05). During the non-CPB period (T 0, T 1, T 3), the cutoff values of PSV-ICA and Q-ICA in predicting rScO 2< 60% were 51.35 cm/s and 283.5 ml/min respectively, the sensitivity was 0.900 and 0.900 respectively, and the specificity was 0.610 and 0.857 respectively (AUC=0.761, P=0.006; AUC=0.903, P< 0.001). During the CPB period, the cutoff values of Q-ICA and Q/CO in predicting rScO 2<60% were 296.5 ml/min and 5.84% respectively, the sensitivity was 0.900 and 0.800, and the specificity was 0.545 and 0.659 (AUC=0.764, P=0.001; AUC=0.748, P=0.002), respectively. Conclusions:PSV-ICA and Q-ICA are positively correlated with rScO 2 during the non-CPB period, and Q-ICA and Q/CO are positively correlated with rScO 2 during the CPB period in elderly patients undergoing CABG. PSV-ICA, Q-ICA and Q/CO can accurately predict rScO 2<60%.

Objective:To analyse the differences of related genes between serum alpha-fetoprotein (AFP) positive gastric cancer and AFP negative gastric cancer, and the relationship between related genes and prognosis of serum AFP positive gastric cancer.Methods:A total of 1 144 gastric cancer patients undergoing surgery at the 940th Hospital , Joint Logistic Support Force, People's Liberation Army from Jan 2013 to Dec 2018 were retrospectively analyzed. Of them, 47 cases were of AFP positive gastric cancer, and 47 serum AFP negative case were obtained by proper matching method.Results:Forty-seven patients with serum AFP positive gastric cancer, accounting for 4.1% of all gastric cancer patients during the same period. The prognosis of serum AFP negative gastric cancer is better than that of serum AFP positive gastric cancer. The 1-, 3- and 5-year cumulative survival rates were 95.6% vs. 63.8%, 48.9% vs. 23.4% and 26.7% vs. 14.9%, respectively. There were statistical differences in the immunohistochemistry of AFP, HER2, VEGF, GPC3, SALL4, P53 and Ki67 between the two groups ( χ2=67.758, P<0.001; χ2=4.004, P=0.044; χ2=19.299, P<0.001; χ2=5.232, P=0.022; χ2=6.359, P=0.012; χ2=6.224, P=0.013; χ2=5.232, P=0.022). The more co-positive expressions of AFP, GPC3, VEGF and SALL4, the more likely they were to affect pTNM stage, vascular invasion and liver metastasis ( χ2=5.328, P=0.021; P=0.013; χ2=5.887, P=0.015; χ2=3.923, P=0.048). Univariate and multivariate survival analysis of serum AFP positive gastric cancer showed:AFP, GPC3, VEGF and SALL4 were risk factors for AFP positive gastric cancer ( HR=3.700, P=0.036; HR=4.237, P=0.003; HR=3.916, P=0.004; HR=3.412, P=0.001). Conclusions:Serum AFP positive gastric cancer is a rare and highly invasive special type of gastric cancer. AFP, GPC3, VEGF and SALL4 are overexpressed in serum AFP positive gastric cancer, which is correlated with tumor stage, vascular invasion and liver metastasis. The final diagnosis of serum AFP positive gastric cancer still needs immunohistochemical examination. Preoperative serum AFP level is an important basis for AFP positive gastric cancer screening and AFP immunohistochemical examination.
