OBJECTIVE To investigate the effects and mechanisms of oliceridine fumarate (TRV130) in improving postoperative cognitive dysfunction (POCD) in elderly rats based on the Toll-like receptor 4 (TLR4)/nuclear factor-κB (NF-κB) pathway. METHODS Rats were randomly divided into the control group (normal saline), the model group (normal saline), the TRV130 group (2.8 mg/kg), the TLR4/NF-κB pathway inhibitor (TAK-242) group (3 mg/kg), the β -arrestin inhibitor (Barbadin) group (3 mg/kg), and the traditional opioid drug (morphine) group (2.8 mg/kg), with 15 rats in each group. Except for the control group, POCD models were established in all other groups. From the first day after surgery, drugs/normal saline were administered via caudal vein injection once daily for 3 consecutive days. After the last administration, the pathological damage of hippocampal tissue was observed; the cognitive function, serum inflammatory factor levels, hippocampal neurons apoptosis rate, and the expression of ionized calcium-binding adapter molecule 1 (Iba-1), glial fibrillary acidic protein (GFAP), and TLR4/NF-κB pathway-related mRNA and protein in hippocampal tissue were detected. RESULTS In the model group, the neurons in the CA1 region of the hippocampus were disordered and sparse, with decreased number, pyknotic and fragmented nuclei accompanied by inflammatory cell infiltration. Compared with the control group, the escape latency, serum levels of tumor necrosis factor α (TNF-α), interleukin-6 (IL-6), and IL-1β, hippocampal neurons apoptosis rate, average fluorescence intensities of Iba-1 and GFAP, mRNA expression levels of TLR4 and NF-κB p65, and their protein expression/phosphorylation levels in hippocampal tissue were significantly increased/elevated in the model group ( P <0.05); the time spent in the target quadrant and the number of platform crossings were significantly shortened/decreased ( P <0.05). Compared with the model group, the cognitive function, pathological, inflammatory, and apoptosis-related indicators were significantly improved in the TRV130 group, TAK-242 group, and Barbadin group ( P <0.05); the mRNA expression levels of TLR4 and NF-κB p65 and their protein expression/phosphorylation levels were significantly decreased in the TRV130 group and TAK-242 group ( P <0.05). CONCLUSIONS TRV130 may improve POCD in elderly rats by inhibiting the TLR4/NF-κB pathway and alleviating postoperative central nervous system inflammatory responses.

Objective:
To investigate if high glucose (HG) exacerbates Porphyromonas gingivalis (P.g) lipopolysaccharide (LPS)-induced inflammatory response in human gingival fibroblasts (HGFs) and to explore the underlying mechanisms. To provide a basis for the mechanism of diabetes aggravating periodontitis.
Methods:
HGFs were divided into four groups: the control group (basal medium), the LPS group (treated with 5 μg/mL P.g-LPS for 24 h), the HG group (treated with 25 mmol/L glucose for 24 h), and the HG+LPS group (treated with 25 mmol/L glucose + 5 μg/mL P.g-LPS for 24 h). After culturing for 24 h in the respective media, the cells were harvested for experiments. Intracellular reactive oxygen species (ROS) and mitochondrial reactive oxygen species (mtROS) were detected using 2 ', 7' - dichlorodihydrofluorescein diacetate (DCFH-DA) and MitoSOX Red staining, respectively. Fluorescence intensity was analyzed by confocal fluorescence microscopy and directly measured in cell suspension. Immunofluorescence was used to detect changes in mitochondrial DNA (mtDNA) content of HGFs. Real-time fluorescence quantitative PCR was used to detect the content of mtDNA in cytoplasm and cell supernatant. Protein expression of the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway was assessed by western blot, while mRNA expression levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) were detected by PCR.
Results:
Compared to the control group, both the LPS group and the HG group exhibited a significant increase in ROS and mtROS, with a more pronounced elevation in the HG+LPS group, demonstrating a synergistic effect (ROS: F = 396.5, P < 0.001; mtROS: F = 29.38, P < 0.001, CI < 1). The cytoplasmic mtDNA content was significantly elevated in the LPS group, with a more marked increase in the HG+LPS group (F = 27.85, P < 0.001). The supernatant mtDNA levels were significantly higher in both the LPS and HG groups, with a more pronounced elevation in the HG+LPS group (F = 15.26, P < 0.001). The phosphorylated proteins p-STING, p-TBK1, and p-P65 in the cGAS-STING pathway showed varying degrees of activation in the LPS and HG groups, reaching the highest levels in the HG+LPS group (p-STING: F = 52.67, P < 0.001; p-TBK1: F = 15.67, P = 0.001; p-P65: F = 9.83, P = 0.005), while p-IRF3 showed no significant differences among the groups (P = 0.072). Pro-inflammatory cytokine TNF-α was significantly higher in the HG+LPS group compared to the control group (F = 15.05, P < 0.001), and IL-1β increased in both the LPS and HG groups, with a more pronounced rise in the HG+LPS group (F = 30.98, P < 0.001). IL-6 showed no significant differences among the groups (P = 0.847).
Conclusion
High glucose and LPS act synergistically to enhance oxidative stress, accompanied by increased mtDNA release, which activates the cGAS-STING pathway, thereby amplifying the inflammatory response in HGFs.

Objective:To investigate the relationship between circular RNA (circRNA) circ-DCAF7 and the survival of prostate cancer patients, as well as the effects and potential mechanisms of circ-DCAF7 on proliferation and migration of prostate cancer cells in vitro.Methods:The expression and survival data of circ-DCAF7 gene were obtained from 151 prostate cancer patients using the PROGgeneV2 online platform. Patients were divided into circ-DCAF7 high and low expression groups based on the median expression level of circ-DCAF7 gene, and the difference in overall survival between the two groups was compared. Real-time fluorescence quantitative polymerase chain reaction (qPCR) was used to detect the expression of circ-DCAF7 at transcription level in human prostate cancer cell lines 22Rv1, VCaP, PC-3, DU-145, LNCaP, and human normal prostate epithelial cell line RWPE-1. The control plasmid (carrying irrelevant control sequences) and the plasmid carrying circ-DCAF7 sequences were transfected into VCaP cells using liposome reagents, respectively, and referred to as the control group and circ-DCAF7 group. The proliferation and migration abilities of two groups of VCaP cells were detected by plate clone formation assay and cell scratch assay, respectively; using CircInteractome online software, specific binding sites were predicted between circ-DCAF7 and miRNA-18a-5p (miR-18a-5p) sequences, and validated using dual luciferase reporter gene assay; qPCR was used to detect the expression of miR-18a-5p at transcription level in VCaP cells of control group and circ-DCAF7 group; Western blotting was used to detect the expression levels of AKT signaling pathway factors p-AKT, p-mTOR, HIF-1α, and c-myc proteins in two groups of VCaP cells.Results:Analysis using the PROGgeneV2 online tool showed that the overall survival of prostate cancer patients in the circ-DCAF7 high expression group was better than that in the circ-DCAF7 low expression group, and the difference was statistically significant ( P < 0.001). Compared with the normal prostate epithelial cell line RWPE-1, the relative expression of circ-DCAF7 at transcription level in all prostate cancer cell lines was lower, and the differences were statistically significant (all P < 0.05). Among them, the expression level of circ-DCAF7 in VCaP cells was the lowest ( P < 0.001). The relative expression of circ-DCAF7 at transcription level in VCaP cells in the circ-DCAF7 group was higher than that in the control group (9.88±1.58 vs. 1.04±0.39), and the difference was statistically significant ( t = 5.42, P = 0.002). The number of VCaP cell clone formation in the circ-DCAF7 group was less than that in the control group (35±12 vs. 116±11), and the difference was statistically significant ( t = 4.96, P = 0.003). The 25-hour scratch healing rate of VCaP cells in the circ-DCAF7 group was lower than that in the control group [(16±3)% vs. (52±6)%], and the difference was statistically significant ( t = 5.37, P = 0.002). The dual luciferase reporter gene assay showed that compared with VCaP cells co-transfected with miR-18a-5p unrelated control and carrying wild-type circ-DCAF7 sequence plasmid, the relative luciferase activity of VCaP cells co-transfected with miR-18a-5p and carrying wild-type circ-DCAF7 sequence plasmid was lower, and the difference was statistically significant ( t = 7.31, P < 0.001). The relative expression of miR-18a-5p at transcription level in VCaP cells in the circ-DCAF7 group was lower than that in the control group (0.99±0.15 vs. 7.55±1.12), and the difference was statistically significant ( t = 5.83, P = 0.001). Western blotting analysis showed that the expression levels of p-AKT, p-mTOR, HIF-1α, and c-myc proteins of the AKT signaling pathway in VCAP cells of the circ-DCAF7 group were lower than those in the control group. Conclusions:The low expression level of circRNA circ-DCAF7 may be associated with poor prognosis of prostate cancer patients; upregulation of circ-DCAF7 level in prostate cancer cells may inhibit cell proliferation and migration by regulating the miR-18a-5p/AKT signaling pathway.

Objective:To explore the distribution variation of ultrasound-detected inflammatory lesions with clinical signs in patients with psoriatic arthritis (PsA).Methods:This was based on the Peking University First Hospital Psoriatic Arthritis (PKUPsA) cohort. Patients enrolled from January 2019 to June 2024 were inchuded, patients with complete data of physical examination and ultrasonographic evaluations of 62 joints in the hand and foot. The ultrasound-detected inflammatory lesions including synovitis, tenosynovitis, enthesitis, and soft tissue inflammation were compared with joint tenderness/swelling. The χ2 test was employed to analyze differences between groups. Results:A total of 7 440 joints in 120 PsA patients were included. Overall, the proportion of joints with clinical signs (tenderness or swelling) was higher than those with ultrasound-detected inflammatory lesions [9.14%(680/7 440) vs. 7.93%(590/7 440), χ2=1 245.928, P<0.001], with more tenderness joints than swelling joints [7.72%(574/7 440) vs. 6.14%(457/7 440), χ2=3 264.45, P<0.001]. Clinical signs were primarily observed in hand proximal interphalangeal (PIP), distal interphalangeal (DIP), wrist and ankle joints, mostly in DIP2 joints [19.58%(47/240)]. Ultrasound-detected inflammatory lesions were predominantly found in metatarsophalangeal (MTP), wrist, and ankle joints, mostly in MTP2 joints (18.75%, 45/240). Clinical signs were more prevalent than ultrasound-detected inflammatory lesions in hand PIP1-3, PIP5, DIP2, and DIP5 joints ( P<0.05), whereas more frequent ultrasound-detected inflammatory lesions than clinical tenderness/swelling were in MTP1-4 joints ( P<0.05). Among ultrasound-detected inflammatory lesions, synovitis in MTP2 joints (18.75%, 45/240), tenosynovitis in ankle joints (10.00%, 24/240), enthesitis in hand DIP2 joints (8.75%, 21/240), and soft tissue inflammation in MTP4 joints (2.50%, 6/240) most commonly observed. Dactylitis was more frequently observed in toes than in fingers, with the fourth toe most commonly affected(16.67%, 40/240). Ultrasound-detected inflammatory lesions were observed in 72.37%(55/240) of fingers/toes with clinical dactylitis, mainly presenting as synovitis, tenosynovitis, or combinations of these. Conclusion:PsA exhibits significant heterogeneity in the inflammatory lesions across different joints and lesion types. The discrepancies between clinical findings and ultrasonic inflammatory changes highlight the limitations of physical examination in fully capturing the pathological features of PsA. As a critical tool for PsA evaluation, ultrasonography offers distinct advantages in detecting subclinical inflammation and differentiating inflammatory from non-inflammatory lesions.

AIM: To compare the outcome of C3F8 versus silicone oil tamponade after pars plana vitrectomy(PPV)and inverted internal limiting membrane(ILM)for the treatment of highly myopic macular hole retinal detachment(MHRD).METHODS: Retrospective clinical study. Totally 45 patients(45 eyes)with highly myopic MHRD who visited our hospital between January 2019 and August 2022 were selected as the research subjects. The patients were divided into two groups according to different intraocular tamponade agents: C3F8(22 eyes)and silicone oil(23 eyes)groups. All patients underwent conventional three-incision PPV, ILM was tamped, a venous blood clot was placed on the tamped ILM, and 15% C3F8 and silicone oil were used as tamponade, respectively. The best corrected visual acuity(BCVA), multifocal electroretinogram(mfERG), the closure of the macular hole, retinal reattachment and the complications were observed.RESULTS: The macular hole closure rate was 77% in the C3F8 group and 83% in the silicone oil group, respectively(P>0.05), and retinal reattachment rates were 95% and 96%, respectively(P>0.05). The visual acuity of the two groups significantly improved, which was 0.99±0.34 and 1.22±0.37, respectively, and the C3F8 group was better than that of the silicone oil group(t=-2.156, P=0.037). After operation, the response density of the first ring of P1 wave in the first order kernel in mfERG was 114.27±26.37 nV/deg2 for the C3F8 group and 98.08±24.36 nV/deg2 for the silicone oil group, and the response density of the second ring of P1 wave was 80.45±14.94 nV/deg2 for the C3F8 group and 67.73±15.33 nV/deg2 for the silicone oil group, all of which were significantly higher compared to pre-operation [the response density of the first ring of P1 wave: 58.13±13.96 nV/deg2 for the C3F8 group and 55.30±10.48 nV/deg2 for the silicone oil group, the response density of the second ring of P1 wave: 51.18±8.19 nV/deg2 for the C3F8 group and 47.43±11.97 nV/deg2 for the silicone oil group](all P<0.05). It was found that the response density of the first ring of P1 wave was lower in the silicone oil group than in the C3F8 group(P<0.05). There was no statistically significant difference in the incidence of complications between the two groups(P>0.05).CONCLUSION: Silicone oil tamponade or C3F8 tamponade after PPV combined with ILM can both promote retinal reattachment and macular hole closure in patients with MHRD, and the C3F8 tamponade was superior to silicone oil in visual function recovery.

Objective:By observing the effects of Calycosin on the proliferation and migration of human renal cancer 769-P cell, to explore the possible molecular mechanism of Calycosin against renal cancer.Methods:769-P cell were cultured with different concentrations of Calycosin [0, 12.5, 25, 50, 100, 200 μmol/L, dissolved in Dimethyl sulfoxide (DMSO)], and the effects of different concentrations of Calycosin on the viability of 769-P cell was detected by CCK8 method. The 769-P cell treated with 200 μmol/L Calycosin were used as the Calycosin group, and the 769-P cell treated with DMSO were used as the control group. The cell colony formation assay and cell scratch assay were used to detect the effects of Calycosin on the proliferation and migration of 769-P cell, respectively. Real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) was used to detect the effect of Calycosin on the expression of miRNA-1246 and chemokine receptor-4 (CXCR4) in 769-P cell. Western blotting method was used to detect the effects of Calycosin on the expression of CXCR4 and extracellular signal-regulated kinase (ERK) pathway proteins in 769-P cell. Measurement data were expressed as mean ± standard deviation ( ± s), and one-way ANOVA was used for comparison between multiple groups, while t-test was used for comparison between two groups. Results:After cultured with 0, 12.5, 25, 50, 100, and 200 μmol/L of Calycosin, the absorbance values of renal cancer 769-P cell were 0.99 ± 0.06, 0.74 ± 0.07, 0.60 ± 0.03, 0.55 ± 0.05, 0.40 ± 0.06, 0.21 ± 0.04, respectively; compared with 0 μmol/L, the Calycosin could reduce the survival rate of 769-P cell ( P<0.05). The number of clones of 769-P cell in the control group and the Calycosin group was 109.80 ± 13.19 and 60.66 ± 11.22, respectively, and the number of clones of the 769-P cell in the Calycosin group was decreased, the difference was statistically significant ( t=5.67, P<0.01). The relative migration rates of 769-P cell in the control group and the Calycosin group were (43.13 ± 3.82)% and (14.27 ± 3.25)%, respectively, after the 769-P cell were treated with Calycosin, the cell migration ability was weakened ( t=5.71, P<0.05). The relative expression levels of miRNA-1246 in 769-P cell of the control group and the Calycosin group was 1.03 ± 0.12 and 6.99 ± 1.84, respectively, and the relative expression levels of CXCR4 mRNA was 7.17 ± 2.96 and 0.98 ± 0.06, respectively, showed that Calycosin can up-regulate the expression of miRNA-1246 in 769-P cell ( t=3.24, P<0.01), and down-regulate the expression of CXCR4 mRNA ( t=4.18, P<0.01). Compared with the control group, the Calycosin could down-regulate the expression of CXCR4 protein and ERK pathway protein in 769-P cell. Conclusion:Calycosin can inhibit the proliferation and migration of renal cancer 769-P cell, and its mechanism may be related to up-regulating the expression of miRNA-1246 and blocking the CXCR4/ERK pathway.

Objective:To explore the effect of long non-coding RNA (lncRNA) C10orf25 on the proliferation and invasion ability of prostate cancer cells and the possible role of miRNA-671-5p (miR-671-5p).Methods:Data from the Gene expression omnibus (GEO) database (data updated in January 2023) were used to analyze the differences in the expression levels of C10orf25 in 137 cases of prostate cancer tissues and paracancerous tissues. Prostate cancer C4-2B, DU-145, 22Rv1, PC-3, LNCaP cell lines and immortalized prostate epithelial RWPE-1 cell lines were selected, and then real-time quantitative fluorescence polymerase chain reaction (qRT-PCR) was used to detect the relative expression levels of C10orf25 in cell lines. The 22Rv1 cells with the lowest relative expression level of C10orf25 were selected and divided into the control group (transfected with negative plasmid) and the C10orf25 group (transfected with C10orf25 plasmid); the CCK-8 method was used to detect the proliferation activity of 22Rv1 cells in both groups at day 1, 2, 3, 4, 5 (expressed as absorbance value); the Transwell method was used to detect the invasion ability of 22Rv1 cells. Linc2GO software was used to predict miR-671-5p with binding sites for C10orf25. Dual luciferase reporter gene assay was used to verify the targeting relationship between C10orf25 and miR-671-5p. qRT-PCR was used to detect the relative expression levels of C10orf25 and miR-671-5p. Western blot was used to detect the expression of proteins related to the NF-κB signaling pathway of 22Rv1 cells in the both groups.Results:In the GEO database, the relative expression level of C10orf25 in prostate cancer tissues was lower than that in paracancerous tissues ( P < 0.01). The relative expression levels of C10orf25 in immortalized prostate epithelial cell line RWPE-1 and prostate cancer cell lines C4-2B, DU-145, 22Rv1, PC-3, and LNCaP were 1.00±0.05, 0.63±0.04, 0.42±0.03, 0.18±0.04, 0.81±0.02, 0.50±0.07, and the difference was statistically significant ( F = 43.29, P < 0.05). The proliferation ability of 22Rv1 cells in C10orf25 group was lower than that in the control group from the second day, and the differences were statistically significant (all P < 0.05). The number of invasive cells in the control group and C10orf25 group were (97±11) and (36±9), respectively, and the difference was statistically significant ( t = 4.15, P < 0.01). Linc2GO software prediction results showed that C10orf25 had a binding site for miR-671-5p. The dual luciferase reporter gene assay showed that the relative luciferase activity of miR-671-5p and C10orf25 wild plasmid co-transfecting 22Rv1 cells was lower than that of miR-NC and C10orf25 wild plasmid co-transfecting 22Rv1 cells, and the difference was statistically significant ( P < 0.01); when miR-671-5p or miR-NC was co-transfected with C10orf25 mutant plasmid, the difference in the luciferase activity of 22Rv1 cells was not statistically significant ( P > 0.05). The relative expression levels of miR-671-5p in 22Rv1 cells were 7.33±0.99 and 0.98±0.16, respectively in the control group and C10orf25 group, and the difference was statistically significant ( t = 6.32, P < 0.01). The results of Western blot showed that the expression levels of NF-κB signaling pathway protein p50, matrix metalloproteinase 9, c-myc, and vascular endothelial growth factor protein in 22Rv1 cells in C10orf25 group were lower than those in the control group. Conclusions:The overexpression of C10orf25 may inhibit the proliferation and invasion of prostate cancer cells through the miR-671-5p-NF-κB axis.

Senior care workers specializing in traditional Chinese medicine (TCM) healthcare have become an indispensable force in institutional care, community care, and home care. The first Chinese nursing service team aimed to improve the health of the elderly by providing continuous services for physical and mental well-being, disease prevention, physical amelioration, and overall health enhancement using TCM concepts, methods, and technologies. The primary purpose of formulating this TCM health and elderly care worker service specification was to standardize services within the TCM elderly care industry, ensuring that the elderly receive better health and elderly care services supported by technical expertise. This specification outlined the basic requirements for TCM health and elderly care workers, including standards for service content, service quality control, service evaluation, and improvement. It primarily focused on the content and requirements of TCM health and elderly care services, such as constitution identification, life care, acupoint healthcare, and TCM auxiliary nursing for elderly individuals with chronic diseases. This specification is applicable to TCM health and elderly care personnel at various levels of hospitals and healthcare institutions and is noted for its strong applicability and effectiveness.
