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.

Aim To investigate the effect of Shenqi Dihuang decoction(SQDH)on henoch-schonlein pur-pura nephritis(HSPN)rats by regulating AMPK/Sirt1/Nrf2 mediated ferroptosis and the possible mech-anism.Methods Thirty SD rats were randomly divid-ed into a control group(Control),HSPN group,SQDH low-dose group(SQDH-L,5.4 g·kg-1),SQDH high-dose group(SQDH-H,21.6 g·kg-1),and SQDH high-dose+AMPK inhibitor group(SQDH-H+CC,20 mg·kg-1),with six rats in each group.Except for the control group,all other groups of rats were injected intraperitoneally with ovalbumin and complete Freund's adjuvant to establish HSPN rat models.After the successful construction of the model,each group of rats was orally administered with the cor-responding dosage or physiological saline once a day for five weeks.HE staining was used to observe the his-topathological changes in renal tissues;immunohisto-chemistry(IHC)was employed to detect the deposition of IgA and IgG in renal tissues;serum biochemical pa-rameters of renal function and urinary protein levels were measured;commercial assay kits were utilized to determine oxidative stress markers and Fe2+levels in renal tissues;Western blot analysis was performed to assess ferroptosis-related proteins and the protein ex-pression of the AMPK/Sirt1/Nrf2 signaling pathway in renal tissues.Results Compared with the control group,the HSPN group showed significant pathological damage in kidney tissue,with significantly increased scores,increased deposition of IgA and IgG in kidney tissue,decreased serum total protein(TP)and albu-min(ALB),and average increases in serum creatinine(Cre),urea nitrogen(BUN),and urinary protein levels(P＜0.05).The levels of MDA,ROS,Fe2+,and ACSL4 protein expression in the kidney tissue sig-nificantly increased,while SOD activity,SLC7A11,GPX4,p-AMPK/AMPK,Sirt1,and Nrf2 protein ex-pression significantly decreased(P＜0.05).Com-pared with the HSPN group,the pathological damage to renal tissue was reduced,IgA and IgG deposition in renal tissue decreased,TP and ALB decreased,Cre,BUN,and urinary protein levels were all reduced(P＜0.05),and the levels of MDA,ROS,Fe2+,and ACSL4 protein expression in renal tissue were signifi-cantly reduced in each dose group of SQDH rats.SOD activity,SLC7A11,GPX4,p-AMPK/AMPK,Sirt1,and Nrf2 protein expression significantly increased(P＜0.05).Compared with the SQDH-H group,the AMPK inhibitor CC could inhibit the AMPK/Sirt1/Nrf2 signaling pathway induced ferroptosis and reverse the protective effect of SQDH on renal injury in HSPN rats.Conclusions SQDH can improve renal injury in HSPN rats,and its mechanism may be related to the activation of AMPK/Sirt1/Nrf2 signaling pathway to in-hibit ferroptosis.

Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.
