AIM: To evaluate the postoperative clinical efficacy of non-diffractive extended depth of focus intraocular lens(EDOF IOL)in patients with highly myopic cataract(HMC).METHODS:A retrospective analysis was conducted on the clinical data of patients diagnosed with HMC at the hospital from January 2022 to December 2024. Patients were divided into an observation group [undergoing femtosecond laser-assisted cataract surgery(FLACS)combined with non-diffractive EDOF IOL implantation] and a control group(undergoing FLACS combined with aspheric monofocal IOL implantation)according to the type of implanted IOL. Postoperative visual acuity(LogMAR), visual quality, and patient satisfaction were compared between the two groups.RESULTS: A total of 33 patients(47 eyes)were finally included in this study, including 10 patients(17 eyes)in the observation group and 23 patients(30 eyes)in the control group. The observation group had a median age of 59.0(52.8, 63.8)y, with 8 males(13 eyes)and 2 females(4 eyes). The control group had a median age of 56.0(53.5, 60.0)y, with 13 males(17 eyes)and 10 females(13 eyes). At 3 mo postoperatively, the best-corrected distance visual acuity(BCDVA)was 0.10(0.08, 0.12)in the observation group and 0.20(0.10, 0.40)in the control group(P=0.586). However, the best-corrected intermediate visual acuity(BCIVA)[0.10(0.10, 0.10)vs 0.50(0.40, 0.90), P=0.032] and best-corrected near visual acuity(BCNVA)[0.20(0.18, 0.20)vs 0.60(0.45, 1.45), P=0.044] in the observation group were significantly better than those in the control group. The defocus curve showed that the uncorrected visual acuity(UCVA)in the observation group was relatively stable within the range of -2.00 to +1.00 D, which was superior to that in the control group. Postoperative questionnaires showed that the spectacle independence rate(76%)and overall satisfaction(88%)in the observation group were significantly higher than those in the control group(10% and 60%, respectively).CONCLUSION: Non-diffractive EDOF IOL significantly improves intermediate and near visual acuity, reduces spectacle dependence, and maintains distance visual acuity by extending the depth of focus, providing better postoperative visual quality and life satisfaction for HMC patients.

Objective: To investigate the current status of benefit finding among young and middle-aged patients with type 2 diabetes mellitus (T2DM) and analyze its influencing factors, so as to provide a reference for improving the level of benefit finding in this population. Methods: From November 2022 to May 2023, young and middle-aged patients with T2DM aged 18-59 years hospitalized in the endocrinology departments of 2 tertiary hospitals in Hengyang City, Hunan Province were selected as survey subjects by a convenience sampling method. Basic demographic information was collected using a general questionnaire survey. Benefit finding, resourcefulness, and stigma were evaluated using the Benefit Finding Scale, the Chinese Version of the Resourcefulness Scale, and the Type 2 Diabetes Stigma Assessment Scale, respectively. A multiple linear regression model was used to analyze the influencing factors of benefit finding among young and middle-aged patients with T2DM. Results: A total of 305 young and middle-aged patients with T2DM were investigated, including 222 males (72.79%) and 83 females (27.21%). There were 231 cases aged 45-59 years, accounting for 75.74%. The scores for benefit finding, resourcefulness, and stigma were (42.86±6.06), (75.12±11.30), and (41.20±10.10), respectively. Multiple linear regression analysis showed that young and middle-aged patients with T2DM who were male (β′=0.088), aged 18-<45 years (β′=0.083), absence of diabetes complications (β′=0.124), and had higher resourcefulness scores (β′=0.679) had higher levels of benefit finding, while patients with higher stigma scores (β′=-0.097) had lower levels of benefit finding. Conclusion The level of benefit finding among young and middle-aged patients with T2DM was moderate, and was related to gender, age, diabetes complications, resourcefulness, and stigma.

OBJECTIVE To investigate the mechanism by which Shenfukang capsule （SFK） ameliorates renal interstitial fibrosis （RIF） by regulating macrophage-fibroblast crosstalk via the signal transducer and activator of transcription 3 （STAT3）/Yes-associated protein （YAP） pathway. METHODS RAW264.7 macrophages were induced to polarize with transforming growth factor-β 1 （TGF-β 1 ）. Subsequently， a non-contact co-culture system of macrophages with renal fibroblasts NRK-49F， as well as a non-contact co-culture system of macrophages with YAP-knockdown renal fibroblasts， were established. Cells were treated with low， medium， and high concentrations （4， 8， 16 μg/mL） of SFK， as well as a STAT3 inhibitor （STAT3-I，1.64 μg/mL） and losartan potassium tablets （positive control， 0.28 μg/mL）， for 48 h. After intervention， the protein and mRNA expression levels of CD86， CD163， and STAT3 in macrophages， as well as CD86， F4/80， and STAT3 mRNA， were detected. In co-cultured renal fibroblasts， the protein and mRNA expression levels of α -smooth muscle actin （ α -SMA）， Vimentin， collagen type Ⅰ （Col-Ⅰ）， matrix metalloproteinase-1 （MMP-1）， and YAP were detected. In co-cultured YAP-knockdown renal fibroblasts， the protein and mRNA expression levels of α -SMA， Vimentin， and MMP-1 were also detected. RESULTS Following TGF-β 1 induction， the protein expression levels of CD86， CD163， and STAT3， as well as the mRNA expression levels of CD86， F4/80， and STAT3 in macrophages were significantly increased （ P ＜0.05）. The conditioned medium from polarized macrophages activated renal fibroblasts， as evidenced by significantly increased protein and mRNA expression levels of α -SMA， Vimentin， Col-Ⅰ， and YAP， and significantly decreased protein and mRNA expression levels of MMP-1 in renal fibroblasts （ P ＜0.05）. Treatment with SFK and STAT3-I reversed the changes in the above indicators， with the medium concentration SFK group showing stronge r effects on some indicators than the low and high concentration groups. In the non-contact co-culture experiment of macrophages and YAP-knockdown renal fibroblasts， there were no statistically significant differences in the protein and mRNA expression of α-SMA， Vimentin， and MMP-1 among the groups. CONCLUSIONS SFK can inhibit macrophage-renal fibroblast crosstalk by blocking the STAT3/YAP pathway， thereby delaying the progression of RIF.

Perineural invasion (PNI) by tumor cells is a key phenotype of highly-invasive oral squamous cell carcinoma (OSCC). Since Schwann cells (SCs) and fibroblasts maintain the physiological homeostasis of the peripheral nervous system, and we have focused on cancer-associated fibroblasts (CAFs) for decades, it's imperative to elucidate the impact of CAFs on SCs in PNI⁺ OSCCs. We describe a disease progression-driven shift of PNI^- towards PNI⁺ during the progression of early-stage OSCC (31%, n = 125) to late-stage OSCC (53%, n = 97), characterized by abundant CAFs and nerve demyelination. CAFs inhibited SC proliferation/migration and reduced neurotrophic factors and myelin in vitro, and this involved up-regulated ER stress and decreased MAPK signals. Moreover, CAFs also aggravated the paralysis of the hind limb and PNI in vivo. Unexpectedly, leukemia inhibitory factor (LIF) was exclusively expressed on CAFs and up-regulated in metastatic OSCC. The LIF inhibitor EC330 restored CAF-induced SC inactivation. Thus, OSCC-derived CAFs inactivate SCs to aggravate nerve injury and PNI development.

Objective To investigate the mechanism of astragalus polysaccharide(APS)in inhibiting the proliferation and metastasis of osteosarcoma cells.Methods Cell counting kit-8(CCK8)assay was used to detect the inhibitory effect of APS on the proliferation of osteosarcoma cell lines U2OS,HOS,MG63 and osteoblast cell line hFOB1.19,the cell line with the most significant inhibitory effect of APS on osteosarcoma cells was selected for subsequent experiments.Osteosarcoma cells were divided into control group(NC group),APS group,APS+sh-SP1 co treatment group with transfected SP1 knockdown plasmid(APS+sh-SP1),and APS+oe SP1 co treatment group with transfected SP1 overexpression plasmid(APS+oe SP1 group).Western blotting was used to detect the expression of SP1 protein in each group.CCK8 assay was used to detect the proliferation ability of each group.Transwell assay was used to detect the metastatic ability of cells in each group.TOP/FOP Flash assay was used to detect the activity of Wnt/β-catenin signaling pathway.The protein expressions of Wnt3a,β-catenin,CyclinD1,cMYC,matrix metalloproteinase 2(MMP2)and Snail were detected by western blotting.Result After 48h of APS treatment,the cell proliferation inhibition rates of osteosarcoma cells U2OS,HOS,MG63 and osteoblast cells hFOB1.19 were 62.93%±4.79%,20.66%±1.10%,39.31%±3.20%and 5.97%±0.72%,respectively.Compared with osteoblast hFOB1.19,APS significantly inhibited the proliferation of osteosarcoma cells,and the difference was statistically significant(F=208.400,P<0.001),and the inhibitory effect on osteosarcoma U2OS cells was the most significant(t=20.380,P<0.001).Compared with NC group,SP1 protein expression,cell proliferation ability,number of transmembrane cells,Wnt/β-catenin signaling pathway activity in cells,Wnt/β-catenin signaling pathway key proteins Wnt3a,β-catenin,downstream proliferation-related protein CyclinD1,cMYC,and downstream metastasis related proteins MMP2 and Snail in the APS group were decreased,and the differences were statistically significant(t=9.740～90.780,all P<0.05).Compared with the APS group,the expression of SP1 protein,cell proliferation ability,the number of transmembrane cells,the activity of Wnt/β-catenin signaling pathway and the expression of Wnt/β-catenin signaling pathway related proteins in the APS+sh-SP1 group were further decreased,and the differences were statistically significant(t=3.032～12.940,all P<0.05).Compared with the APS group,the expression of SP1 protein,cell proliferation ability,the number of transmembrane cells,the activity of Wnt/β-catenin signaling pathway and the expression of Wnt/β-catenin signaling pathway related proteins in the APS+oe-SP1 group were increased,and the differences were statistically significant(t=3.350～22.450,all P<0.05).Conclusion APS inhibits the proliferation and metastasis of osteosarcoma cells by targeting SP1/Wnt/β-catenin signaling axis.

BACKGROUND:The imbalance between proliferation and apoptosis of chondrocytes plays an important role in the occurrence and development of osteoarthritis. Previous studies have found that hsa-miR-3202 is involved in regulating the proliferation and apoptosis of various cells. However,no studies have explored the correlation between hsa-miR-3202 and osteoarthritis.OBJECTIVE:To investigate the expression of hsa-miR-3202 in osteoarthritic chondrocytes and its effect on the proliferation and apoptosis of chondrocytes. METHODS:(1) MicroRNAs differentially expressed in osteoarthritic chondrocytes were screened by biogenic analysis. Based on the current research situation at home and abroad,hsa-miR-3202 was selected for follow-up studies,and its target genes were predicted by gene ontology (GO) functional enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment. (2) Human normal chondrocyte cell lines C28/I2 in logarithmic growth phase were selected and randomly divided into four groups for culture:in normal group,cells were cultured in normal medium for 24 hours,the medium was then changed to normal medium for another 6 hours of culture,and changed to normal medium for subsequent culture;in lipopolysaccharide group,cells were cultured in lipopolysaccharide-containing medium for 24 hours,the medium was then changed to normal medium for another 6 hours,and changed to normal medium for subsequent culture;in lipopolysaccharide+NC group,cells were cultured in lipopolysaccharide-containing medium for 24 hours,and then transfected with has-miR-3202 mimics control for 6 hours,and the medium was change to normal medium for subsequent culture;in lipopolysaccharide+hsa-miR-3202 mimics group,cells were cultured in lipopolysaccharide-containing medium for 24 hours and then transfected with has-miR-3202 mimics for 6 hours,and the medium was changed to normal medium for subsequent culture. After further 48 hours of culture,the expression level of hsa-miR-3202 was detected by fluorescence quantitative PCR and cell apoptosis was detected by flow cytometry. After further culture of 0-72 hours,cell proliferation activity was detected by cell counting kit-8. RESULTS AND CONCLUSION:Bioinformatics analysis results indicated that hsa-miR-3202 was significantly down-regulated in osteoarthritic chondrocytes. GO functional enrichment and KEGG pathway enrichment showed that the function of hsa-miR-3202 target gene was closely related to cell growth and apoptosis. The results of in vitro cell experiments showed that compared with the normal group,the expression level of hsa-miR-3202 and proliferation ability of chondrocytes were significantly decreased in the lipopolysaccharide group (P<0.05),while the apoptotic rate was significantly increased (P<0.05). Compared with the lipopolysaccharide group,the expression level of hsa-miR-3202 and proliferation ability of chondrocytes were significantly increased in the lipopolysaccharide+hsa-miR-3202 mimics group (P<0.05),while the apoptotic rate was significantly decreased (P<0.05). To conclude,the expression of hsa-miR-3202 is down-regulated in osteoarthritic chondrocytes to inhibit cell proliferation and promote cell apoptosis,thus affecting the occurrence and development of osteoarthritis.

Objective:To explore the feasibility, safety, and effectiveness of a novel suture instrument for closure of full thickness defects of the gastric wall under gastroscopy.Methods:Ten pigs were used as experimental animals. Perforation model (30 mm in long diameter) was created in the stomach of each pig. The perforations were then closed by the novel suture instrument under gastroscopy. The completion time and efficacy of each perforation repair were recorded. The pigs were euthanized 14 days after the procedure. The healing condition was observed under gastroscopy. A postmortem examination was performed to observe the abdominal infection and healing condition of perforation. Ascites sample was taken for bacterial culture.The stomach biopsy were taken for histopathologic examination.Results:All gastric perforation models in the 10 pigs were established successfully. Endoscopic closure for the stomach perforation was technically successful in all 10 pigs. The procedure time was 34.10±10.32 minutes. All animals survived. Gastroscopy and necropsy showed that the perforation healed well with local adhesion. One pig developed abdominal infection. Ascites culture were negative in 9 cases, 1 bacterial infection was caused by Arcanobacterium pyogenes and Escherichiacoli. The pathology results showed that the muscular layer of the gastric wall defect in the entire group was well repaired. Conclusion:The novel suture instrument is safe and effective in repairing full-thickness gastric wall defects under ordinary single clamp gastroscopy, providing an experimental basis for further clinical research.
