Objective To explore the relationship between the triglyceride glucose(TyG)index and 2-year cognitive function changes.Methods A total of 101 elderly patients who were hospitalized at Quanzhou First Hospital Affiliated to Fujian Medical University from September to December 2022 were selected.The cognitive function was evaluated using Montreal cognitive assessment(MoCA)scale.According to the baseline TyG index,the subjects were divided into high TyG index group(TyG index≥ 8.79,51 cases)and low TyG index group(TyG index＜8.79,50 cases).Using a binary Logistic regression model to adjust for confounding factors,the association between TyG index and cognitive decline was analyzed.Results The Spearman correlation analysis results showed that TyG index was negatively correlated with the change value of cognitive function(r=-0.243,P＜0.05).The incidence of cognitive function decline in high TyG index group was significantly higher than that in low TyG index group(43.1％vs.24.0％,P=0.042).After adjusting for confounding factors,the risk of cognitive function decline in high TyG index group was 2.971 times that of low TyG index group(P＜0.05).Conclusion The TyG index of elderly hospitalized patients is correlated with 2-year cognitive function changes.The TyG index may serve as a potential biomarker for early detection of cognitive function decline.

Aim To investigate the role of tryptophan 2,3-dioxygenase(TDO2)in cisplatin-acute kidney in-jury(Cis-AKI)and to explore the mechanism of TDO2 in relation to apoptosis in tubular epithelial cells(TECs)to investigate the mechanism of TDO2 associ-ated with apoptosis.Methods An AKI model was es-tablished by intraperitoneal injection of cisplatin(Cis).Colorimetric assay was used to detect CRE and BUN levels,and PAS staining was employed to observe renal injury in mice.Immunohistochemistry was used to detect TDO2 protein expression and distribution and macrophage(F4/80+)infiltration;immunofluores-cence was used to detect the co-localization of TDO2 with the tubular marker LTL;TUNEL staining was used to detect apoptosis in mouse kidney;flow cytome-try was used to detect overexpression of human renal cortical proximal tubular epithelial cells(HK2)and apoptosis after administration of the TDO2 inhibitor 680C91;Western blot was used to detect TDO2 and NF-κB pathway protein levels in HK2 cells after over-expression and inhibition of TDO2.Results In the o-verall animal experiments,Cis-AKI mice showed signif-icantly higher levels of CRE and BUN and obvious tu-bular damage compared with the control group;at the same time,the renal tissues of Cis-AKI mice showed increased expression of F4/80,and the proportion of apoptotic cells in kidney cells was increased.Immuno-histochemistry and immunofluorescence showed that the expression of TDO2 increased,mainly localized in TECs.In cellular experiments,HK2 cells overexpress-ing TDO2 increased the proportion of apoptosis,and the expression of TDO2,p-IKBα,and p-p65 proteins was elevated,and p-IKBα/IκBα and p-p65/p65 were ele-vated;furthermore,the proportion of apoptosis was re-duced by the administration of 680C91,and the expres-sion of p-IκBα,and p-p65 proteins decreased,and the expression of p-IKBα/IKBα,and p-p65/p65 de-creased.Conclusions Elevated TDO2 in TECs is in-volved in the pathological mechanism of Cis-AKI,which may be related to its induction of apoptosis in TECs and activation of the NF-κB signaling pathway and consequently renal injury.

This study explored the effects and underlying mechanism of Raf kinase inhibitory protein(RKIP)on apoptosis in mast cells sensitized by Echinococcus granulosus cyst fluid.Bone marrow-derived mast cells(BMMCs)were isolated and cultured from RKIP knockout(KO)and wild-type(WT)C57BL/6 mice.Cells were divided into control and sensitized groups.The sensitized group was incubated for 24 h in RPMI1640 medium containing 10%serum from mice infected with E.granulosus,then activated for 3 h or 6 h with E.granulosus cyst fluid.The control group was incubated for 24 h in RPMI1640 medium,and then received an equal vol-ume of PBS.Cells and supernatants were collected for analysis.Flow cytometry was used to detect the expression of CD117 and FcεRⅠα on BMMCs.The levels of β-hexosaminidase,IL-4,and TNF-α in the supernatant were quantified with ELISA.Western blot analy-sis was used to assess expression changes in RKIP,apoptosis-related proteins,and pathway proteins in BMMC before and after sensi-tization.Flow cytometry analysis revealed that after 4 weeks of induction,the CD117 and FcεRⅠα double-positivity rates on both WT and KO BMMC exceeded 90%.ELISA indicated that the E.granulosus cyst fluid resulted in significantly greater β-hexosaminidase re-lease(F=16.88,P<0.05),and levels of IL-4(F=16.51,P<0.05)and TNF-α(F=9.78,P<0.05)in the KO sensitized group than the WT sensitized group.With respect to the WT control group,the WT sensitized group showed significantly down-regulated pro-tein expression levels of RKIP(F=8.20,P<0.05)and Bcl-2(F=101.40,P<0.01)after 3 h,but significantly up-regulated levels of p-PI3K(F=8.04,P<0.05),p-Akt(F=32.52,P<0.01),p-P65(F=13.29,P<0.05),and cleaved-caspase-3(F=46.34,P<0.01).With respect to the WT sensitized group,the KO sensitized group showed significantly up-regulated protein expression of p-PI3K(F=8.45,P<0.05),p-Akt(F=8.58,P<0.05),p-P65(F=11.02,P<0.05),and Bcl-2(F=84.50,P<0.001)after 3 h,but significantly down-regulated expression of cleaved-caspase-3(F=15.66,P<0.05).In conclusion,RKIP may inhibit the PI3K/Akt/NF-κB pathway,thereby inducing apoptosis in mast cells sensitized by E.granulosus cyst fluid.This process may help ease aller-gic reactions caused by mast cells in echinococcosis,thus offering a promising new approach for preventing and treating such reactions.

Objective:To analyze the effects of low-molecular-weight heparin combined with insulin (LMWH+INS) and double filtration plasmapheresis (DFPP) on lipid profiles and clinical outcomes in patients with hypertriglyceridemic acute pancreatitis (HTG-AP) based on propensity score matching.Methods:The clinical data of 126 patients with HTG-AP from October 2022 to February 2024 in The Third Affiliated Hospital of Nanjing Medical University, Changzhou Traditional Chinese Medicine Hospital Affiliated to Nanjing Traditional Chinese Medicine University and Changzhou First People's Hospital were retrospectively included. Patients were divided into LMWH+INS group ( n=87) and DFPP group ( n=39) according to the treatment. Propensity score matching was applied at a 1∶1 ratio. The repeated measures analysis of variance was conducted to assess dynamic changes of blood lipids within the 5 days of admission between the LMWH+INS and DFPP groups after matching. Clinical symptoms and outcomes were compared between the two matched groups following matching. Results:29 patients were included in both LMWH+INS group and DFPP group after propensity score matching. No statistically significant differences were observed in triglycerides (TG), acute physiology and chronic health evaluation Ⅱ(APACHEⅡ) score, or bedside index for the severity of acute pancreatitis (BISAP) between the two groups (all P value >0.05), indicating comparability. Repeated measures analysis of variance revealed that TG and TC levels in the DFPP group were significantly lower than those in the LMWH+INS group at 2-5 days after admission [TG 2 d: (5.26±2.59) mmol/L vs (10.79±3.81) mmol/L, 3 d: (3.35±1.01) mmol/L vs (7.72±3.64) mmol/L, 4 d: (3.45±0.77) mmol/L vs (6.57±3.17) mmol/L, 5 d: (3.73±1.26) mmol/L vs (5.61±3.07) mmol/L; TC 2 d: (4.83±2.29) mmol/L vs (8.2±2.82) mmol/L, 3 d: (4.23±2.17) mmol/L vs (7.71±2.68) mmol/L, 4 d: (4.28±1.59) mmol/L vs (7.55±2.41) mmol/L, 5 d: (4.1±1.21) mmol/L vs (7.84±2.6) mmol/L], with a more rapid decrease. LDL levels in the LMWH+INS and DFPP groups showed similar trends, with significant decreases at 2 day after admission [(5.41±3.24) mmol/L vs (2.96±1.47) mmol/L, (4.99±3.51) mmol/L vs (2.47±1.53) mmol/L]. The differences mentioned above are all statistically significant (all P value <0.001). No significant changes were observed in HDL levels in either LMWH+INS and DFPP groups at 2-5 days after admission. After matching, the DFPP group had a significantly longer time of resuming feeding [3(2, 3) days vs 4(3, 6) days] and higher hospital cost [12113.87 (9055.31, 14401.84) yuan vs 28025.34 (25388.11, 36335.48) yuan] compared with the LMWH+INS group, with statistically significant differences. Conclusions:DFPP could reduce TG and TC levels more rapidly and effectively than LMWH combined with INS, but does not show an advantage in improving clinical outcomes and reducing hospitalization costs.

Objective To explore the effect of low density lipoprotein-cholesterol(LDL-C)on the diameters of retinal arteries and veins in patients with type 2 diabetes mellitus(T2DM).Methods A total of 102 patients with T2DM who treated in Quanzhou First Hospital Affiliated to Fujian Medical University from January to September 2024 were selected and divided into Group A(LDL-C＜2.6mmol/L,35 cases),Group B(2.6mmol/L≤LDL-C＜3.4mmol/L,33 cases)and Group C(LDL-C≥3.4mmol/L,34 cases)according to the LDL-C level.The clinical data and color fundus photos of the patients were collected.The superior temporal retinal arteriolar equivalent(RAE)and superior temporal retinal venular equivalent(RVE)in the left eye of patients were measured,and the ratio of arteriovenous diameters(AVR)was calculated.The correlation between LDL-C levels and retinal vascular diameters was analyzed.Results There were statistically significant differences in levels of total cholesterol and triglycerides,as well as the proportions of patients with coronary heart disease and diabetic retinopathy(DR)among the three groups(P＜0.05).With the progression of DR,the level of LDL-C gradually increases(P＜0.05).There were statistically significant differences in RAE and AVR among patients with different DR stages(P＜0.05).There were statistically significant differences in RAE and AVR among three groups of patients(P＜0.05).Correlation analysis showed that RAE and AVR were negatively correlated with LDL-C(P＜0.05).Conclusion With the increase of LDL-C level,the degree of DR aggravates,and RAE and AVR decrease accordingly.However,there is no significant correlation between LDL-C and RVE.

Background/Aims: Endoscopic radiofrequency ablation (ERFA) is a treatment option for superficial esophageal squamous cell neoplasia (ESCN), with a relatively low risk of stenosis; however, the long-term outcomes remain unclear. We aimed to compare the long-term outcomes of patients with widespread superficial ESCN who underwent endoscopic submucosal dissection (ESD) or ERFA. Methods: We retrospectively analyzed the clinical data of patients with superficial ESCN who underwent ESD or ERFA between January 2015 and December 2021. The primary outcome measure was recurrence-free survival. Results: Ninety-two and 33 patients with superficial ESCN underwent ESD and ERFA, respectively. The en bloc, R0, and curative resection rates for ESD were 100.0%, 90.2%, and 76.1%, respectively. At 12 months, the complete response rate was comparable between the two groups (94.6% vs 90.9%, p=0.748). During a median follow-up of 66 months, recurrence-free survival was significantly longer in the ESD group than in the ERFA group (p=0.004), while no significant differences in overall survival (p=0.845) and disease-specific survival (p=0.494) were observed.Preoperative diagnosis of intramucosal cancer (adjusted hazard ratio, 5.55; vs high-grade intraepithelial neoplasia) was an independent predictor of recurrence. Significantly fewer patients in the ERFA group experienced stenosis compare to ESD group (15.2% vs 38.0%, p=0.016). Conclusions The risk of recurrence was higher for ERFA than ESD for ESCN but overall survival was not affected. The risk of esophageal stenosis was significantly lower for patients who underwent ERFA.
