Objective To investigate the effectiveness of the integrated schistosomiasis control programme in Sichuan Province during the stage moving from transmission interruption to elimination (2015—2023), so as to provide insights into formulation of the schistosomiasis control measures during the post-elimination stage. Methods Schistosomiasis control data were retrospectively collected from departments of health, agriculture and rural affairs, forestry and grassland, water resources, and natural resources in Sichuan Province from 2015 to 2023, and a database was created to document examinations and treatments of human and livestock schistosomiasis, and snail survey and control, conversion of paddy fields to dry fields, ditch hardening, rivers and lakes management and building of forests for snail control and schistosomiasis prevention. The completion of schistosomiasis control measures was investigated, and the effectiveness was evaluated. Results A total of 20 545 155 person-times received human schistosomiasis examinations in Sichuan Province during the period from 2015 to 2023, and 232 157 person-times were seropositive, with a reduction in the seroprevalence from 2.10% (44 299/2 107 003) in 2015 to 1.12% (9 361/837 896) in 2023 (χ² = 7.68, P < 0.001). The seroprevalence of human schistosomiasis appeared a tendency towards a decline in Sichuan Province over years from 2015 to 2023 (b = −8.375, t = −10.052, P < 0.001); however, no egg positive individuals were identified during the period from 2018 to 2023, with the prevalence of human Schistosoma japonicum infections maintained at 0. Expanded chemotherapy was administered to 2 754 515 person-times, and medical assistance of advanced schistosomiasis was given to 6 436 persontimes, with the treatment coverage increasing from 46.80% (827/1 767) in 2015 to 64.87% (868/1 338) in 2023. Parasitological tests for livestock schistosomiasis were performed in 35 113 herd-times, and expanded chemotherapy was administered to 513 043 herd-times, while the number of fenced livestock decreased from 121 631 in 2015 to 103 489 in 2023, with a reduction of 14.92%. Snail survey covered 433 621.80 hm² in Sichuan Province from 2015 to 2023, with 204 602.81 hm² treated by chemical control and 4 637.74 hm² by environmental modifications. The area of snail habitats decreased from the peak of 5 029.80 hm² in 2016 to 3 709.72 hm² in 2023, and the actual area of snail habitats decreased from the peak of 8 585.48 hm² in 2016 to 473.09 hm² in 2023. The mean density of living snails remained low across the study period except in 2017 (0.62 snails/0.1 m²). Schistosomiasis control efforts by departments of agriculture and rural affairs in Sichuan Province included conversion of paddy fields to dry fields covering 153 346.93 hm², hardening of 6 110.31 km ditches, building of 70 356 biogas digesters, replacement of cattle with 227 161 sets of machines, and captive breeding of 21 161 070 livestock from 2015 to 2023, and the control efforts by departments of water resources included rivers and lakes management measuring 5 676.92 km and renovation of 2 331 irrigation areas, while the control efforts by departments of forestry and grassland included building of forests for snail control and schistosomiasis prevention covering 23 913.33 hm², renovation of snail control forests covering 8 720 hm² and newly building of shelterbelts covering 764 686.67 hm². All 63 endemic counties (cities and districts) had achieved the criterion for schistosomiasis elimination criteria in Sichuan Province by the end of 2023. Conclusion Following the integrated control efforts from 2015 to 2023, remarkable achievements have been obtained in the schistosomiasis control programme in Sichuan Province, with all endemic counties successfully attaining the schistosomiasis elimination target at the county level.

Aim To investigate the effect of Dahuang Tangluo pills(DHTL)on NOD-like receptor protein 3(NLRP3)/cysteine aspartate proteolytic enzyme-1(caspase-1)/apodermic D(GSDMD)pathway-media-ted pyroptosis in db/db mice with diabetic kidney dis-ease(DKD)and the underlying mechanism.Methods Eight db/m mice were selected as control group,and forty db/db mice were randomly divided into mod-el group,low dose group,medium dose group,high dose group and dapagliflozin group,with eight mice in each group.The control group and model group were given equal volume normal saline intragastric adminis-tration,the low,medium and high dose groups were given DHTL solution of 0.9,1.8 and 3.6 mg·kg-1,respectively,and the dapagliflozin group was given dapagliflozin tablet solution of 1.5 mg·kg-1,and the six groups were given intragastric administration once a day for 10 weeks.The body weight of mice was meas-ured daily and the dose was adjusted during adminis-tration.Fasting blood glucose(FBG)and body weight were measured after administration.The levels of 24-hour urinary total protein(24h-UTP),blood creatinine(Scr)and urea nitrogen(BUN)were measured by au-tomatic biochemical analyzer.The levels of interleukin-1 β(IL-1β),interleukin-6(IL-6),interleukin-18(IL-18)and tumor necrosis factor-α(TNF-α)in re-nal tissue of mice were determined by enzyme-linked immunosorbent assay(ELISA).The pathological changes of renal tissue were observed by hematoxylin-eosin(HE)staining.The DNA damage in mouse kid-ney tissue was observed using in situ end labeling(TUNEL)staining.The mRNA and protein expres-sions of NLRP3,caspase-1 and GSDMD in mouse kid-ney tissues were detected by Real-time quantitative PCR and Western blot.Results Compared with the control group,FBG,body weight,IL-1β,IL-6,IL-18 and TNF-α in the model group significantly increased(P＜0.01).The mRNA and protein expressions of NLRP3,caspase-1 and GSDMD in mouse kidney tis-sues significantly increased(P＜0.01).Compared with the model group,the levels of FBG,body weight,IL-1β,IL-6,IL-18 and TNF-α in each administration group significantly decreased(P＜0.05).The patho-logical morphology of renal tissue was improved in dif-ferent degrees,and the number of positive cells in re-nal tissue was significantly reduced(P＜0.05).The mRNA and protein expressions of NLRP3,caspase-1 and GSDMD in renal tissue of mice in high and medi-um dose of DHTL and dapagliflozin group significantly decreased(P＜0.05).Conclusions DHTL can im-prove the renal injury of DKD,and its mechanism may be through the regulation of NLRP3/caspase-1/GSD-MD pathway to inhibit pyroptosis and relieve the in-flammatory response of DKD mice.

Aim To explore the protective effect of an-thocyanin B2(PCB2)on hydrogen peroxide(H2O2)induced oxidative damage and apoptosis in human oli-godendrocytes(MO3.13)and the underlying mecha-nism.Methods The optimal concentration of H2O2 and PCB2 for action was screened,and divided into normal group,PCB2 group(100 mg·L-1 PCB2 treat-ment for 24 hours),H2 O2 model group(500 μmol·L-1 H2O2 treatment for 24 hours),and H2O2+PCB2 group(500 μmol·L-1 H2O2 and 100 mg·L-1 PCB2 co-treated for 24 hours).FRAP method was used to detect the antioxidant capacity of PCB2;CCK-8 meth-od was used to detect the survival rate of cells in each group,while LDH method was used to assess cytotoxic-ity.Microenzyme-linked immunosorbent assay and ELISA were used to examine the levels of LDH,NO,H2O2,as well as the activities of CAT and SOD in each group of cells.Immunofluorescence and Western blot were used to detect the protein expression levels of NRF2,xCT,HO-1,ferritin,and GPX4 in each group of cells.FerroOrange fluorescent probe was used to de-tect the intracellular content of ferrous ions(Fe2+).Results H2O2 could induce MO3.13 oxidative dam-age and lead to cell ferroptosis,while PCB2 could alle-viate MO3.13 oxidative damage and ferroptosis.Com-pared with the H2O2 model group,PCB2 intervention could significantly increase LDH content in MO3.13,reduce NO and H2O2 content,and improve SOD and CAT activity,and up-regulate the protein expression levels of NRF2,xCT,HO-1,ferritin,and GPX4.Conclusion PCB2 can enhance cellular antioxidant capacity and alleviate H2O2 induced MO3.13 oxidative damage through the NRF2/HO-1/xCT/GPX4 axis.

Aim To investigate the effect of Xuanfuhua decoction combined with sorafenib on liver cancer bearing mice and the underlying mechanism.Methods KM mice were divided into the liver cancer group,Xuanfuhua decoction group,sorafenib group,combina-tion group,combination+PTEN inhibitor(BPV)group,combination+PI3K activator(IGF-1)group and blank group.Liquid chromatography-mass spec-trometry was used to detect the blood components of Xuanfuhua decoction in serum of mice in liver cancer group and Xuanfuhua decoction group.The changes of serum ALT,AST,tumor weight and tumor volume were detected.The pathological changes of tumor tissue,the proportion of TUNEL,p53 and Bax positive cells,the levels of IFN-γ and TNF-α,and the protein changes of PTEN,p-PI3K and p-AKT were detected.The effects of combined treatment on the proliferation and apopto-sis of H22 cells of mouse hepatoma were observed in vitro.Results There were 11 constituents absorbed into blood of Xuanfuhua decoction.Compared with the liver cancer group,the tumor cells in the Xuanfuhua decoction group,sorafenib group,and combination group were dispersed,the serum AST and ALT levels,tumor weight,tumor volume,and p-PI3K and p-AKT proteins decreased,the proportion of TUNEL,p53 and Bax positive cells,IFN-γ,TNF-α levels,and PTEN protein in tumor tissue increased,and the trend of the combination group was the most obvious(P＜0.05).BPV or IGF-1 reversed the anti-tumor effect of the combined treatment on liver cancer bearing mice.In vitro experiments showed that the combined treatment could inhibit the proliferation of H22 cells and promote the apoptosis of H22 cells better than Xuanfuhua de-coction or sorafenib alone.BPV or IGF-1 reversed the effects of combined treatment on the proliferation and apoptosis of H22 cells.Conclusion Xuanfuhua de-coction combined with sorafenib may exert anti-tumor effect on liver cancer bearing mice by up-regulating PTEN and inhibiting PI3K/AKT pathway.

The aim of this study was to investigate the impact of overexpressing 70-kD heat shock pro-teins(Hsp70)on glycolysis in C2C12 cells during myogenesis and adipogenesis.Using C2C12 cells as the research material,adenovirus was used to overexpress the Hsp70 gene,and changes in the expression of glycolytic genes were detected using fluorescence quantitative PCR and Western blotting techniques.The study indicated that during C2C12 cell myogenic differentiation,the expression trend of the Hsp70 gene was consistent with that of Gsk3β,Pkm,Prkag3,Pfkm,and Hk-2 genes,suggesting a relationship between Hsp70 and the glycolytic pathway during myogenic differentiation.Overexpression of Hsp70 in the later stages of myogenic differentiation significantly upregulated the expression of Gsk3β,Pkm,Prk-ag3,and Pfkm genes(P＜0.05),with no significant impact on Hk-2 gene expression(P＞0.05).Dur-ing C2C12 cell adipogenic induction,the expression trend of the Hsp70 gene was similar to that of Gsk3β,Pkm,Prkag3,Pfkm,and Hk-2 genes,indicating a relationship between Hsp70 and the glycolytic path-way during adipogenic induction.Following Hsp70 overexpression,in the later stages of adipogenic in-duction,the number of lipid droplets was significantly higher compared to the control group,with a sig-nificant upregulation of Gsk3β,Pkm,Prkag3,and Pfkm gene expression(P＜0.05),while Hk-2 gene expression was not significantly affected(P＞0.05).In conclusion,Hsp70 in C2C12 cells in myogenic and adipogenic states promoted the breakdown of glycogen into 6-phospho-glucose,thereby enhancing the glycolytic pathway,providing insights into the functional role of the Hsp70 gene in glycolysis in C2C12 cells.

To determine the efficacy and safety of selinexor combined with venetoclax (VEN) and azactitidine (AZA) for patients with relapsed and/or refractory acute myeloid leukemia (R/R AML) . Twelve patients with R/R AML treated with selinexor plus VEN and AZA in the Affiliated Cancer Hospital of Zhengzhou University from May 2022 to May 2023 were included. Their clinical data were retrospectively analyzed. Among the 12 R/R AML patients, 5 (41.7%) achieved complete remission (CR) , 1 (8.3%) achieved CR with incomplete hematological recovery, and 5 (41.7%) achieved partial remission. The median time to reach CR was 28 (16-59) days. The median PFS was 61 (15-300) days. The main adverse event of the regimen was hematological toxicity. No chemotherapy-related deaths were observed. The combination of selinexor plus VEN and AZA is an effective treatment for R/R AML patients.

Objective To explore the influencing factors of mild cognitive impairment(MCI)in patients with atrial fibrillation and diabetes mellitus,and to establish the prediction model,so as to provide guidance for the treatment of MCI in patients with atrial fibrillation and diabetes mellitus.Methods 199 patients with atrial fibrillation and diabetes diagnosed in the second ward of Cardiovascular Department of the Fifth Affiliated Hospital of Zhengzhou University from January 2023 to January 2024 were analyzed.The related factors of MCI in patients with atrial fibrillation and diabetes mellitus were analyzed by univariate analysis and multivariate logistic regres-sion.According to the results of multivariate logistic regression analysis,the prediction model of MCI in patients with atrial fibrillation and diabetes mellitus was established.Results Univariate analysis showed that age(P=0.002 3),homocysteine(P＜0.000 1),fasting blood glucose(P=0.022 5),glycated hemoglobin(P=0.006 6),and blood uric acid(P=0.032 2)were the influencing factors of MCI.Multivariate logistic regression analysis:age(OR=1.08,P=0.000 4),homocysteine(OR=1.37,P＜0.000 1),fasting blood glucose(OR=1.22,P=0.023 5),glycated hemoglobin(OR=1.61,P=0.004 2),and blood uric acid(OR=1.29,P=0.009 1)were the independent influencing factors of MCI.The optimal threshold is when the Youden index(YI=sensitivity+speci-ficity)is maximum.At the optimal threshold,the sensitivity was 0.74,the specificity was 0.80,and the area under the curve(AUC)was 0.809,indicating that the model can effectively predict the occurrence of MCI.Conclusion Age,fasting blood glucose,blood homocysteine,blood uric acid and glycosylated hemoglobin are independent risk factors for MCI in patients with atrial fibrillation and diabetes.The clinical prediction model based on multivariate logistic regression has a certain predictive value for the occurrence of MCI in patients with atrial fibrillation and diabetes mellitus.

Objective:To comprehensively evaluate the clinical value of Elecsys serum abnormal prothrombin (PIVKA-Ⅱ) test reagent for auxiliary diagnosis of hepatocellular carcinoma (HCC) in the Chinese population.Methods:A multicenter case-control design was used in the study. Samples from patients with first-time confirmed, diagnosed, and untreated HCC, benign liver disease and interfering controls were collected continuously. Elecsys PIVKA-II and alpha-fetoprotein (AFP) were tested for analysis. Various clinical details of the subjects were collected and analyzed. The efficacy of PIVKA-II (21.29 ng/ml) and AFP (400 ng/ml) for HCC diagnosis was calculated at specific positive cut-off values. Statistical analysis was performed using the Kruskal-Wallis test or receiver operating characteristic curve.Results:A total of 448 subjects were eventually enrolled from five centers, including 185 HCC cases. PIVKA-II had a higher diagnostic sensitivity and accuracy than AFP (84.86% vs. 30.81% and 89.01% vs. 63.66%) when the benign liver disease group was used as the control group, while the specificity was slightly lower. A sensitive analysis showed that PIVKA-II had a sensitivity of >80% at this specific positive cut-off value in the subgroup of AFP-negative subjects, patients with different etiologies, and HCC patients with multiple Barcelona Clinic liver cancer stages (including early-stage HCC). At the same time, the PIVKA-II subject had a slightly higher area under the receiver operating characteristic curve than the AFP (0.920 0 vs. 0.880 9).Conclusion:The clinical efficacy of Elecsys PIVKA-Ⅱ is good and stable in the Chinese population. Additionally, it has the clinical potential to improve the current missed diagnosis status of AFP-negative HCC and HCC monitoring at an early stage, as well as the effectiveness of accuracy promotion for HCC auxiliary diagnosis in China.
