Glaucoma,characterized by optic nerve damage and progressive damage to retinal ganglion cells(RGCs),is the leading cause of irreversible blindness.However,the specific mechanism of RGC damage has not been fully elucida-ted.In recent years,there is increasing evidence that microglia,especially disease-associated microglia(DAM),may play an important role in glaucomatous ganglion cell injury.In this paper,we reviewed the role and mechanism of DAM in RGC damage in glaucoma,aiming to provide new insights for further research on the mechanism of RGC damage and subsequent protection of RGCs.

Objective To investigate the role and molecular mechanism of SOX4 in Helicobacter pylori(H.pylori)-mediated gastric mucosal epithelial dysplasia.Methods The expression of SOX4 in gastric tissues and cells was analyzed with reverse transcription-polymerase chain reaction(RT-PCR),Western blotting,and immunohistochemical staining.The effects of SOX4 on gastric epithelial cell proliferation and colony formation were determined with CCK-8 and colony formation assays.A PCR array was used to screen downstream target genes involved in H.pylori-induced dysplasia mediated by SOX4.The transcriptional regulation and binding sites of the target gene MLH3 by SOX4 were elucidated with luciferase reporter assay,promoter truncation assay,and chromatin immunoprecipitation(ChIP).Results SOX4 expression was significantly increased in H.pylori-infected gastric tissues(P<0.05).Overexpression of SOX4 markedly enhanced the proliferation and colony formation abilities of normal gastric epithelial cells(P<0.05).Elevated SOX4 led to the dysregulation of MLH3 and other DNA damage repair-related molecules after H.pylori infection in gastric epithelial cells(|logFC|>1,P<0.05).H.pylori promoted MLH3 expression in gastric epithelial cells through SOX4.SOX4 transcriptionally activated MLH3 expression by binding to the 5th site of the MLH3 promoter.The increased expression of SOX4 and MLH3 is associated with poor prognosis of gastric cancer patients.Conclusion SOX4 is closely associated with H.pylori-induced dysplasia in gastric epithelial cells.Upregulation of SOX4 promotes H.pylori-related dysplasia by transcriptionally activating MLH3,leading to the imbalance of proliferation and colony formation in gastric epithelial cells.

Objective To address the current issues of strong subjectivity in drug classification,vague classification standards,and complex influencing factors,this study aims to explore a scientific method for drug classification to reduce inventory costs and improve inventory effectiveness.Methods A total of 700 drugs were randomly selected from the historical data of a tertiary hospital in Beijing from 2021 to 2022 as the research subjects.The classification was conducted using the Principal Component Analysis(PCA)algorithm and the K-means clustering algorithm(K-means).Results The optimal number of classifications was determined to be 4,with a silhouette coefficient of 0.347 0.The 700 drugs were divided into four categories,with 363 in the first category,186 in the second,94 in the third,and 57 in the fourth.The drug classification method studied in this paper was simulated and applied to the drug inventory management of a certain tertiary hospital in the second quarter of 2023.The simulation results indicated that the classification method studied in this paper could reduce inventory costs and improve inventory effectiveness.Conclusion The drug classification method based on PCA algorithm and K-means clustering algorithm can provide a reliable basis for the management of drug inventory classification.

Objective:To investigate the efficacy of rigid ureteroscopic laser lithotripsy combined with N-trap(RULL+N-trap),which is scoop-shaped,in the treatment of ureteral stones with a maximum diameter ≥1.5 cm.Methods:This retrospective cohort study included patients diagnosed with ureteral calculi who underwent rigid ureteroscopic lithotripsy(RULL)combined with N-Trap stone entrapment system at the Department of Urology,Peking University Third Hospital,by the same surgical team between June 2021 and September 2024.A total of 364 patients were initially enrolled.After excluding 21 patients due to missing critical outcome variables,two distinct cohorts were established:38 patients with ureteral stones measuring ≥1.5 cm in maximum diameter,and 305 patients with stones＜1.5 cm in maximum diameter.To minimize selection bias and control for confounding variables,propensity score matching(PSM)was employed.This resulted in two well-balanced groups:31 patients with stones 1.5 cm in maximum diameter and 31 patients with stones＜1.5 cm in maximum diameter,matched on baseline demographic and clinical characteristics.The primary outcomes assessed between the two groups included stone clearance.Secondary outcomes included changes in renal function indicators,specifically serum creatinine(SCr)and estimated glomerular filtration rate(GFR),and other factors like postopera-tive hospital stay and operative time.Results:In the matched cohort,the patients with stones ≥1.5 cm in maximum diameter had significantly longer operative time compared with those with smaller stones:(85.8±28.8)min vs.(62.4±24.6)min(P＜0.05).Postoperative length of hospital stay showed no significant difference:(2.26±1.79)d vs.(2.03±0.80)d(P＞0.05).The stone clearance on postoperative day one was 90.3％in the study group vs.100.0％in the control group(P＞0.05).One month postoperatively,the stone clearance was 93.5％vs.100.0％,respectively(P＞0.05).Changes in SCr were(-6.58±16.10)μmol/L vs.(-13.70±12.50)μmol/L,and changes in GFR were(5.92±14.90)mL/(min·1.73 m2)vs.(7.47±11.20)m L/(min·1.73 m2),with no statistically significant differences observed between the two groups for either renal function marker(P＞0.05).Conclusion:Ureteroscopic lithotripsy combined with N-trap is an optional method for treating ureteral stones with a maximum diameter ≥1.5 cm.The overall therapeutic efficacy is comparable,with the added benefit of significantly reducing the economic burden on patients.

Objective To investigate the effects of preoperative anxiety on the intraoperative body temperature,recessive blood loss,and wound healing in elderly patients undergoing laparoscopic hysterectomy under general anesthesia.Methods A total of 118 elderly patients who underwent laparoscopic hysterectomy in Yancheng Third People's Hospital from January 2021 to December 2023 were selected as the research subjects,and they were divided into the normal group(69 cases with normal emotions)and the anxiety group(49 cases with anxiety emotions)according to the self-rating anxiety scale(SAS)score 1 day before operation.The core temperature at different time points and the incidence of intraoperative hypothermia were compared between the two groups.The intraoperative bleeding volume,incision drainage bleeding volume,recessive blood loss,incidence of adverse reactions,and wound healing were compared between the two groups.Results The core temperature 60 minutes after operation and at the end of operation in the anxiety group were significantly lower than those in the normal group(P<0.05).The incidence of intraoperative hypothermia in the anxiety group was significantly higher than that in the normal group(P<0.05).There was no statistically significant difference in the intraoperative bleeding volume or incision drainage bleeding volume between the two groups(P>0.05),while the recessive blood loss in the anxiety group was significantly higher than that in the normal group(P<0.05).The incidence of shivering in the anxiety group was significantly higher than that in the normal group(P<0.05);the incidence of poor wound healing in the anxiety group was significantly higher than that in the normal group(P<0.05).Conclusion For elderly patients who undergo laparoscopic hysterectomy for more than 60 minutes,the body temperature will significantly decrease,the incidence of intraoperative hypothermia and shivering is high,the recessive blood loss will significantly increase,which is prone to poor wound healing and is not conducive to the rapid recovery of patients after operation,if combined with anxiety before surgery.

Objective:To investigate the effect of transforming growth factor beta 1 (TGF-β1) on the biological activity of infantile hemangioma (IH) -derived endothelial cells (HemECs) .Methods:Three proliferating IH tissues and three involuting IH tissues were collected from IH patients receiving surgical resection at the Department of Pediatric Surgery, West China Hospital, Sichuan University from February to August 2021. Primary HemECs were isolated from proliferating IH tissues, and human umbilical vein endothelial cells (HUVECs) served as the control. The TGF-β1 expression levels in tissues and cells were detected by immunohistochemical study and Western blot analysis. Cell counting kit-8 (CCK8) assay was performed to assess the effect of 0 (control group) - 100 ng/ml TGF-β1 on HemEC proliferation. HemECs were treated with 5 ng/ml TGF-β1 or without (control group), and after several hours of treatment, Transwell assay was performed to evaluate cell migration ability, and immunofluorescence assay to assess the changes in the expression of endothelial markers (platelet-endothelial cell adhesion molecule-1 [CD31], vascular endothelial cadherin [VE-cadherin]) and mesenchymal markers (α-smooth muscle actin [α-SMA], collagen type Ⅰ α 1 [COL1A1]). Comparisons between groups were conducted by t test or one-way analysis of variance. Results:Immunohistochemical study showed that proliferating IH tissues were stained positively for TGF-β1, which was expressed relatively abundantly; the percentages of TGF-β1-positive signal area were higher in the proliferating IH tissues (24.68% ± 3.74%) than in the involuting IH tissues (almost no expression). Western blot analysis revealed that the relative expression level of TGF-β1 was significantly higher in HemECs (1.08 ± 0.13) than in HUVECs (0.30 ± 0.04, t = 9.93, P < 0.001). CCK8 assay showed increased proliferative activity of HemECs in the 3.125-, 6.25-, 12.5-, 25-, 50- and 75-ng/ml TGF-β1 groups compared with the control group (all P < 0.05), and no significant difference was found between the 100-ng/ml TGF-β1 group and the control group ( P > 0.05). Transwell assay revealed an increased number of migratory HemECs in the 5-ng/ml TGF-β1 group (127 ± 6) compared with the control group (103 ± 9; t = 5.32, P < 0.01). Immunofluorescence assay showed significantly decreased fluorescence intensity of endothelial markers CD31 and VE-cadherin in the 5-ng/ml TGF-β1 group (5.441 ± 1.254, 5.073 ± 0.412, respectively) compared with the control group (9.518 ± 1.728,7.671 ± 0.921, t = 3.31, 4.46, P = 0.030, 0.011, respectively), and significantly increased fluorescence intensity of mesenchymal markers α-SMA and COL1A1 in the 5-ng/ml TGF-β1 group (8.074 ± 0.846, 5.885 ± 0.216, respectively) compared with the control group (0.393 ± 0.342, 0.295 ± 0.125, t = 14.58, 38.76, P < 0.001, < 0.000 1, respectively) . Conclusion:TGF-β1 was relatively highly expressed in the proliferating IH tissues and HemECs, and could promote the proliferation, migration and endothelial-to-mesenchymal transition of HemECs.

Objective:To establish a complete system for the isolation, purification, identification, and culture of Kaposiform hemangioendothelioma-derived endothelial cells (KHE-ECs), to analyze the phenotype of KHE-ECs, and to explore the possibility of establishing a KHE-EC bank.Methods:A novel digestion solution for KHE tumors (patent number: CN202410500224.2) was formulated using collection fluid, Liberase TM and dispase stock solutions, and was used to process tumor tissues to obtain cells. High-purity KHE-ECs were purified using CD31 + immunomagnetic beads. The EGM-2 complete medium containing 10% fetal bovine serum and 2% penicillin-streptomycin solution was employed for cell culture. To verify the characteristics of KHE-ECs, immunofluorescence assay was conducted to determine the expression of endothelial cell-specific markers CD31 and CD34, KHE disease markers podoplanin (D2-40), prospero-related homeobox 1 (Prox-1), and lymphatic vessel endothelial hyaluronan receptor 1 (LYVE1), as well as an infantile hemangioma-specific diagnostic marker glucose transporter 1 (GLUT-1). Human umbilical vein endothelial cells (HUVECs) served as controls for the phenotype analysis of KHE-ECs, including cell viability, cytoskeleton, proliferation, migration, invasion, tube formation, and sprouting ability. Results:Primary cells were successfully isolated from KHE tumor tissues, and high-purity KHE-ECs were obtained by using CD31 + immunomagnetic beads. The cells exhibited typical spindle-shaped morphology and an adherent growth pattern. Immunofluorescence assay showed that KHE-ECs expressed CD31, CD34, D2-40, Prox-1, and LYVE1, but did not express GLUT-1. There were significant differences in cell morphology, cell viability, and cytoskeletal structures between KHE-ECs and HUVECs. Additionally, the KHE-EC group showed significantly increased percentages of proliferative cells (29.1% ± 2.5%), numbers of migratory cells (114.3 ± 9.4) and invasive cells (110.0 ± 6.1), tube length (32 121.0 ± 892.0 μm), and number of sprouting cells (25.0 ± 3.6) compared with the HUVEC group (13.0% ± 2.2%, 38.0 ± 3.6, 35.3 ± 2.3, 25 345.0 ± 448.1 μm, 5.0 ± 1.0, respectively, all P ≤ 0.001) . Conclusion:An innovative digestion solution specifically for KHE tumors was formulated for the first time, and high-purity and well-growing KHE-EC strains were successfully isolated and purified by using the novel digestion solution in combination with CD31 + immunomagnetic beads, providing a stable and reliable cell source for subsequent experimental studies on KHE and laying the foundation for establishing a KHE-EC bank.

Objective:To observe the effect of combining transcutaneous stimulation of the auricular vagus nerve (taVNS) with modified constraint-induced movement therapy (mCIMT) on the upper limb function of hemiplegic stroke survivors.Methods:Seventy-one hemiplegic stroke survivors were randomly divided into a taVNS group of 24, an mCIMT group of 23 and a combined group of 24. In addition to conventional rehabilitation therapy, the taVNS group received taVNS therapy, the mCIMT group received mCIMT, while the combined group received both for 30 minutes a day, 5 days a week for 4 weeks. Before and after the treatment, everyone′s upper limb function was evaluated using the Fugl-Meyer upper extremity assessment (FMA-UE) and the Action Research arm test (ARAT). Ability in the activities of daily living (ADL) was quantified using the modified Barthel index (MBI). The latency and amplitude of motor evoked potentials (MEPs) were also measured.Results:After the treatment, significant improvement was observed in the average FMA-UE, ARAT and MBI scores. MEP latency and amplitude had also improved. The averages in the mCIMT group were then significantly better than among the taVNS group.Conclusions:taVNS combined with mCIMT can significantly improve the upper limb function and ADL functioning of stroke survivors with hemiplegia. It can also promote the recovery of central nervous system function.
