Objective To investigate the factors affecting the distribution of Pomacea and project the trends in the spread of suitable distribution areas of Pomacea in 2050 and 2070 in Dali Bai Autonomous Prefecture, so as to provide insights into Pomacea control in the prefecture. Methods The longitudes and latitudes of Pomacea sampling sites were captured based on Pomacea field survey data in 12 cities (counties) of Dali Bai Autonomous Prefecture from 2023 to 2024. A total of 19 climatic factors (annual mean temperature, mean diurnal range, isothermality, temperature seasonality, maximum temperature of the warmest month, minimum temperature of the coldest month, temperature annual range, mean temperature of the wettest quarter, mean temperature of the driest quarter, mean temperature of the warmest month, mean temperature of the coldest month, annual precipitation, precipitation of the wettest month, precipitation of the driest month, precipitation seasonality, precipitation of the wettest quarter, precipitation of the driest quarter, mean temperature of the warmest quarter, and mean temperature of the coldest quarter) and representative concentration pathways (RCPs) were retrieved from the world climate database (www.worldclim.org). All climatic variables were employed to create a maximum entropy (MaxEnt) model. The predictive accuracy of the model was assessed with the area under the receiver operating characteristic (ROC) curve (AUC), and the contributions of these 19 climatic factors to the distribution of Pomacea were analyzed in Dali Bai Autonomous Prefecture using Jackknife test. In addition, the suitable distribution areas of Pomacea were predicted with the MaxEnt model in Dali Bai Autonomous Prefecture in 2024 and in 2050 and 2070 under RCP4.5. Results Data pertaining to 91 Pomacea sampling sites were captured. ROC analysis revealed the MaxEnt model had an AUC value of 0.885 ± 0.088 for predicting the suitable distribution areas of Pomacea in Dali Bai Autonomous Prefecture. Of the 19 climatic factors, the maximum temperature of the warmest month had the highest contribution to the distribution of Pomacea in Dali Bai Autonomous Prefecture, followed by mean temperature of the driest quarter, mean temperature of the wettest quarter and minimum temperature of the coldest month. The suitable distribution area of Pomacea was predicted to be 14 555.69 km² in Dali Bai Autonomous Prefecture in 2024, and would expand gradually to the southeastern part of the prefecture in the future due to climatic factors. The suitable distribution areas of Pomacea were projected to expand to 21 475.61 km² in 2050 and 25 782.52 km² in 2070 in Dali Bai Autonomous Prefecture, respectively. Conclusions Temperature is an important contributor to the distribution of Pomacea in Dali Bai Autonomous Prefecture, and the suitable distribution area of Pomacea will gradually expand to the southeastern part of the prefecture in 2050 and 2070.

Objective To evaluate the potential risk of transmission of angiostrongyliasis by common freshwater snails in Dali Bai Autonomous Prefecture, Yunnan Province, so as to provide insights into local surveillance of angiostrongyliasis. Methods Common freshwater snails were collected from Dali Bai Autonomous Prefecture, Yunnan Province from March to April, 2020, and identified and bred in laboratory. SD rats were infected with third-stage larvae of Angiostrongylus cantonensis that were isolated from commercially available Pomacea canaliculata snails in Dali Bai Autonomous Prefecture, and freshwater snails were infected with the first-stage larvae of A. cantonensis that were isolated from the feces of SD rats 39 days post-infection at room temperature. The developmental process and morphological characteristics of worms in hosts were observed, and the percentages of A. cantonensis infections in different species of freshwater snails were calculated. Then, SD rats were infected with the third-stage larvae of A. cantonensis that were isolated from A. cantonensis-infected freshwater snails, and the larval development and reproduction was observed. Results More than 3 000 freshwater snail samples were collected from farmlands, ditches and wetlands around Erhai Lake in Dali Bai Autonomous Prefecture, and Cipangopaludina chinensis, P. canaliculata, Parafossarulus striatulus, Oncomelania hupensis robertsoni, Galba pervia, Physa acuta, Radix swinhoei, Assiminea spp., Tricula spp. and Bellamya spp. were morphologically identified. A total of 105 commercially available P. canaliculata snails were tested for A. cantonensis infections, and 2 P. canaliculata snails were found to be infected with A. cantonensis, in which the third-stage larvae of A. cantonensis were isolated. Ten species of freshwater snails were artificially infected with the third-stage larvae of A. cantonensis, and all 10 species of freshwater snails were found to be infected with A. cantonensis, with the highest positive rate of A. cantonensis infections in Bellamya spp. (62.3%, 137/204), and the lowest in C. chinensis (35.5%, 11/31). After SD rats were infected with the third-stage larvae of A. cantonensis isolated from different species of freshwater snails, mature adult worms of A. cantonensis were yielded. Conclusions Multiple species of freshwater snails may serve as intermediate hosts of A. cantonensis under laboratory conditions in Dali Bai Autonomous Prefecture of Yunnan Province. Further investigations on natural infection of A. cantonensis in wild snails in Dali Bai Autonomous Prefecture seem justified.

Objective:To evaluate the prognostic significance of clonal gene mutations using next-generation sequencing in patients with core-binding factor acute myeloid leukemia (CBF-AML) who achieved first complete remission after induction chemotherapy.Methods:The study, which was conducted from July 2011 to August 2017 in First Affiliated Hospital of Soochow University, comprised 195 newly diagnosed patients with CBF-AML, including 190 patients who achieved first complete remission after induction chemotherapy. The cohort included 134 patients with RUNX1-RUNXIT1 + AML and 56 patients with CBFβ-MYH11 + AML. The cohort age ranged from 15 to 64 years, with a median follow-up of 43.6 months. Overall survival (OS) and disease-free survival (DFS) were assessed by the log-rank test, and the Cox proportional hazards regression model was used to determine the effects of clinical factors and genetic mutations on prognosis. Results:The most common genetic mutations were in KIT (47.6% ) , followed by NRAS (20.0% ) , FLT3 (18.4% ) , ASXL2 (14.3% ) , KRAS (10.7% ) , and ASXL1 (9.7% ) . The most common mutations involved genes affecting tyrosine kinase signaling (76.4% ) , followed by chromatin modifiers (29.7% ) . Among the patients receiving intensive consolidation therapy, the OS tended to be better in patients with CBFβ-MYH11 + AML than in those with RUNX1-RUNXIT1 + AML ( P=0.062) . Gene mutations related to chromatin modification, which were detected only in patients with RUNX1-RUNXIT1 + AML, did not affect DFS ( P=0.557) . The patients with mutations in genes regulating chromatin conformation who received allo-hematopoietic stem cell transplantation (allo-HSCT) achieved the best prognosis. Multivariate analysis identified KIT exon 17 mutations as an independent predictor of inferior DFS in patients with RUNX1-RUNXIT1 + AML ( P<0.001) , and allo-HSCT significantly prolonged DFS in these patients ( P=0.010) . Conclusions:KIT exon 17 mutations might indicate poor prognosis in patients with RUNX1-RUNXIT1 + AML. Allo-HSCT may improve prognosis in these patients, whereas allo-HSCT might also improve prognosis in patients with mutations in genes related to chromatin modifications.

Objective To investigate the long-term effects of repeated neonatal administration of dizocipline maleate (MK-801),the glutamate N-methyl-D-aspartate (NMDA) receptor antagonist,on recognition memory and hippocampal excitatory-inhibitory balance at the synaptic level in adult female rats.Methods Neonatal female Sprague-Dawley (SD) rats were randomly divided into model group and control group.Rats were administrated subcutaneously with MK-801 or normal saline from postnatal day (PND) 5 to PND14 (0.25 mg/kg,twice daily).(1) Object-in-context recognition test was performed on PND73-75.(2)The expression levels of vesicular glutamate transporter 1 (VGLUT1) and vesicular GABA transporter (VGAT) in hippocampus were detected by immunohistochemical staining.Results (1) The preference index of model group for new objects was significantly lower than that of the control group (t =-2.762,P=0.012).(2) There was no significant difference in the expression of VGLUT1 in hippocampus of MK-801 mode group(P＞0.05).Compared with control group(48.19±2.10),the VGAT level of model group in CA1 (39.60±2.19) was lower.Compared with control group (CA1:(0.99±0.05),CA3:(1.28±0.02),the ratio of VGLUT1/VGAT was significantly upregulated in CA1(1.16±0.05) and CA3(1.44±0.03) (P＜0.05).Conclusion Early NMDA receptor inhibition produces long-term deleterious effects on associative recognition memory and excitatory-inhibitory balance of hippocampus in female rats.These biochemical abnormalities may contribute to cognitive impairments observed in this study.
