Objective To gain insights into the biological characteristics of different populations of Culex tritaeniorhynchus within and around the Yellow Sea wetland from the perspective of the occurrence of resistance, we investigated the levels of resistance to deltamethrin and kdr gene mutation in the wetland and its peripheral areas. Methods Specimens were collected from Cx. tritaeniorhynchus populations at two monitoring sites in the Rare Bird National Nature Reserve and Tiaozi Ni Wetland Scenic Area, and also from two populations in Yancheng City and the Liuhe District of Nanjing, and the resistance of these mosquitoes to deltamethrin was determined using the CDC biotest bottle method. For each concentration of deltamethrin assessed, a random subset of exposed specimens was selected for amplification of the kdr gene fragment, followed by Sanger sequencing to identify and analyze resistance-associated mutations. Results The LC50 levels of deltamethrin among mosquitoes from the four populations in Luhe, Yancheng, the Rare Bird National Nature Reserve and the Tiaozi Ni Wetland Scenic Area were 2.048 5, 7.798 2, 3.473 3, and 17.695 5 mg/mL, respectively, with corresponding concentrations of deltamethrin ranging from 0.005 to 5.000,0.050 to 50.000,0.050 to 25.000 and 0.050 to 50.000 mg/mL, respectively. Furthermore, the ranges of the KT50 values were 11.76-107.43, 67.05-216.30,29.77-107.43 and 28.40-329.51 min; the 1-h knockdown rates were 34.58%-99.15%, 9.52%-43.80%, 55.09%-73.01%, and 10.09%-68.07%; and the 24-h mortality rates were 12.15%-67.52%,9.52%-79.56%,13.17%-82.21%, and 11.01%-78.99%, respectively. With respect to kdr gene mutation, we assayed a total of 63,70,59, and 57 mosquitoes for the four populations, for which we detected L1014F mutation frequencies of 14.29%, 35.00%, 20.34%, and 31.58%, respectively, with a majority of these mutations being heterozygous for resistance. In addition, five adult mosquitoes were identified has having synonymous mutations at site 1011[i. e. , AAT(asparagine)mutation to AAC(asparagine)]. Conclusions Our findings revealed the clear resistance of Cx. tritaeniorhynchus to deltamethrin in the Yancheng region of the Yellow Sea wetland, and the resistance phenotype and kdr frequency of Cx. tritaeniorhynchus in the wetland environment were comparable to those of Cx. tritaeniorhynchus in the wetland environment, thereby indicating that the resistance of different populations of Cx. tritaeniorhynchus was homogeneous under the pressure of different insecticide selection within and around the wetland. However, the underlying mechanisms need to be further studied.

Objective To investigate the impact of high mobility group box 1(HMGB1)on hydrogen peroxide(H2O2)-induced DNA damage and senescence in lens epithelial cells(LECs)under oxidative stress conditions.Methods Fluorescent quantitative real-time polymerase chain reaction(RT-PCR)technology was used to detect the mRNA expres-sion of HMGB1 in the anterior capsule tissue of patients with age-related cataract(ARC group)and epiretinal membrane(control group).Western blot analysis was employed to examine the changes in the protein expression of HMGB1 in the LEC line SRA01/04 after treatment with varying concentrations of H2O2(0,100,200,and 400 μmol·L-1).The optimal concentration was selected for subsequent establishment of a cellular oxidative damage model.The cultured SRA01/04 cells were divided into three groups:Control(untreated),HA(transfected with the control plasmid HA),and OE-HMGB1 groups(transfected with the HMGB1 plasmid).The mRNA and protein expression levels of HMGB1 were detected by RT-PCR and Western blot.The cultured SRA01/04 cells were divided into three groups:H2O2(treated with 400 μmol·L-1 H2O2),H2O2+HA(transfected with the control plasmid HA and simultaneously treated with 400 μmol·L-1 H2O2),and H2O2+OE-HMGB1 groups(transfected with the HMGB1 plasmid and simultaneously treated with 400 μmol·L-1 H2O2).Immunofluorescence was used to detect DNA oxidative damage in cells from each group.Western blot analysis was per-formed to assess the protein expression levels of phosphorylated histone H2A(γH2A),tumor protein p53(P53),cyclin-dependent kinase inhibitor 1A(P21),and cyclin-dependent kinase inhibitor 2A(P16)in cells from each group.Additional-ly,senescence-associated-β-galactosidase(SA-β-gal)staining was conducted to detect senescent changes in cells from each group.Results RT-PCR results indicated that the relative mRNA expression level of HMGB1 in the anterior capsule tissue of the ARC group was significantly decreased,compared with that in the control group(P＜0.001).Furthermore,in the H2O2-induced oxidative damage model,the relative protein expression level of HMGB1 decreased with the increase of the concentration of H2O2.Both RT-PCR and Western blot analyses revealed that the mRNA and protein expression levels of HMGB1 were both significantly elevated in the OE-HMGB1 group,compared with those in the HA group(both P＜0.001).The immunofluorescence staining results demonstrated that the protein expression of γH2A and the fluorescence intensity in the H2O2+OE-HMGB1 group were significantly decreases,compared with those in H2O2 and H2O2+HA groups(all P＜0.001).SA-β-gal staining results showed that the H2O2+OE-HMGB1 group had significantly less cells stained by SA-β-gal than H2O2 and H2O2+HA(both P＜0.001).Additionally,Western blot analysis revealed that,compared with those in H2O2 and H2O2+HA groups,the relative expression levels of senescence-associated proteins P53,P21,and P16 were significantly decreased in the H2O2+OE-HMGB1 group(all P＜0.01).Conclusion HMGB1 inhibits the accumula-tion of damaging DNA and senescence in LECs by enhancing DNA damage repair capabilities.

Objective:To evaluate the clinical efficacy of Tianma Xionglin Zhixuan Tablets in treating hypertension patients with liver yang hyperactivity or comorbid phlegm-stasis syndrome and explore its therapeutic mechanisms through plasma metabolomics.Methods:Thirty-six hypertension patients(4 dropouts)diagnosed with liver yang hyperactivity or phlegm-stasis syndrome were enrolled as the treatment group from June 2022 to September 2023 at the First Affiliated Hospital of Hunan University of Chinese Medicine,while 30 healthy volunteers with balanced constitutions were recruited as the blank group.Plasma samples were collected from patients pre-and post-treatment and from healthy volunteers.Clinical outcomes,including syndrome scores,office blood pressure(BP),and 24-hour ambulatory BP,were recorded.Plasma metabolomic profiling was performed using liquid chromatography-mass spectrometry(LC-MS).Results:Compared with baseline,Tianma Xionglin Zhixuan Tablets significantly reduced traditional Chinese medicine syndrome scores(P＜0.01),office systolic/diastolic BP(P＜0.01),and 24-hour ambulatory BP parameters(24-hour mean BP,daytime/nighttime mean BP;all P＜0.01).Metabolomic analysis identified 45 differential metabolites between the blank group and pretreatment patients,and 64 metabolites altered post-treatment(VIP＞1,P＜0.05).Enrichment analysis of 16 overlapping endogenous metabolites revealed that Tianma Xionglin Zhixuan Tablets primarily modulated arachidonic acid metabolism and sphingolipid metabolism pathways.Conclusion:Tianma Xionglin Zhixuan Tablets demonstrates significant clinical efficacy in hypertension patients with liver yang hyperactivity or phlegm-stasis syndrome,potentially mediated through regulation of arachidonic acid and sphingolipid metabolism.

Objective To investigate the effects of DNA Cross-Link Repair 1A(DCLRE1A)on mitochondrial func-tion in lens epithelial cells(LECs).Methods Thirty eyes from 30 patients with age-related cataracts(ARC)were select-ed and divided into three groups:cortical type(ARCC group),nuclear type(ARNC group),and posterior subcapsular type(ARPC group),with 10 cases in each group.Additionally,10 eyes from 10 age-matched patients diagnosed with epiretinal membrane and having clear lenses were selected as the control group.Western blot was used to detect the ex-pression levels of DCLRE1A protein in the anterior capsule tissues of patients in each group and in the lens epithelial cell line(SRA01/04)treated with hydrogen peroxide(H2O2)in vitro and overexpressed DCLRE1A model(OE-DCLRE1A group).The effects of overexpressed DCLRE1A on the expression levels of mitochondrial transcription factor(TFAM)and peroxisome proliferator-activated receptor-γ coactivator-1α(PGC1α)proteins were also detected.Normal cultured SRA01/04 cells were randomly divided into Control group(untreated),H2 O2 group,H2 O2+HA group(transfected with control plasmid HA),and H2O2+OE-DCLRE1A group(transfected with DCLRE1A plasmid).RT-PCR was used to measure mtD-NA expression in each group cells.Changes in mitochondrial membrane potential(MMP)and mitochondrial reactive oxy-gen species(ROS)in each group were detected by immunofluorescence staining.Results Western blot analysis showed that compared with the control group cells,the relative expression levels of DCLRE1A protein in the anterior capsule tis-sues of patients in the ARCC,ARNC,and ARPC groups were all decreased,with statistically significant differences(all P＜0.001).In the in vitro H2O2-induced oxidative damage model,compared with the Control group,the relative expression level of DCLRE1A protein in the H2O2 group was significantly decreased(P＜0.001).The overexpression efficiency results of DCLRE1A showed that,compared with the Control group,the relative expression level of DCLRE1A protein in the OE-DCLRE1A group cells was significantly increased,with statistical significance(P＜0.001).RT-PCR results showed that compared with the H2O2+HA group,the expression level of mtDNA in the H2O2+OE-DCLRE1A group was significantly in-creased(P＜0.001).Western blot analysis showed that compared with the H2O2+HA group,the relative expression levels of TFAM and PGC1α proteins in the H2O2+OE-DCLRE1A group were significantly increased(P＜0.001).Immunofluores-cence staining results showed that compared with the H2O2+HA group,the MMP level in the H2O2+OE-DCLRE1A group was significantly restored,and the accumulation of mitochondrial ROS was reduced(P＜0.001).Conclusion Under H2O2-induced oxidative stress conditions,DCLRE1A promotes the repair of damaged mtDNA in LECs by regulating mito-chondrial biogenesis,thereby reducing LEC apoptosis and participating in the occurrence and development of ARC.
