Objective To investigate the suitable habitats of Phlebotomus chinensis in Gansu Province, so as provide insights into effective management of mountain-type zoonotic visceral leishmaniasis (MT-ZVL). Methods The geographical coordinates of locations where MT-ZVL cases were reported were retrieved in Gansu Province from 2015 to 2023, and data pertaining to 26 environmental variables were captured, including 19 climatic variables (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 quarter, mean temperature of the coldest quarter, annual precipitation, precipitation of the wettest month, precipitation of the driest month, precipitation seasonality, precipitation of the wettest quarter, precipitation of the driest quarter, precipitation of the warmest quarter, and precipitation of the coldest quarter), five geographical variables (elevation, annual normalized difference vegetation index, vegetation type, landform type and land use type), and two population and economic variables (population distribution and gross domestic product). Twelve species distribution models were built using the biomod2 package in R project, including surface range envelope (SRE) model, generalized linear model (GLM), generalized additive model (GAM), multivariate adaptive regression splines (MARS) model, generalized boosted model (GBM), classification tree analysis (CTA) model, flexible discriminant analysis (FDA) model, maximum entropy (MaxEnt) model, optimized maximum entropy (MAXNET) model, artificial neural network (ANN) model, random forest (RF) model, and extreme gradient boosting (XGBOOST) model. The performance of 12 models was evaluated using the area under the receiver operating characteristic curve (AUC), true skill statistics (TSS), and Kappa coefficient, and single models with high performance was selected to build the optimal ensemble models. Factors affecting the survival of Ph. chinensis were identified based on climatic, geographical, population and economic variables. In addition, the suitable distribution areas of Ph. chinensis were predicted in Gansu Province under shared socioeconomic pathway 126 (SSP126), SSP370 and SSP585 scenarios based on climatic data during the period from 1991 to 2020, from 2041 to 2060 (2050s), and from 2081 to 2100 (2090s) . Results A total of 11 species distribution models were successfully built for prediction of potential distribution areas of Ph. chinensis in Gansu Province, and the RF model had the highest predictive accuracy (AUC = 0.998). The ensemble model built based on the RF model, XGBOOST model, GLM, and MARS model had an increased predictive accuracy (AUC = 0.999) relative to single models. Among the 26 environmental factors, precipitation of the wettest quarter (12.00%), maximum temperature of the warmest month (11.58%), and annual normalized difference vegetation index (11.29%) had the greatest contributions to suitable habitats distribution of Ph. sinensis. Under the climatic conditions from 1991 to 2020, the potential suitable habitat area for Ph. chinensis in Gansu Province was approximately 5.80 × 104 km2, of which the highly suitable area was 1.42 × 104 km2, and primarily concentrated in the southernmost region of Gansu Province. By the 2050s, the unsuitable and lowly suitable areas for Ph. chinensis in Gansu Province had decreased by varying degrees compared to that of 1991 to 2020 period, while the moderately and highly suitable areas exhibited expansion and migration. By the 2090s, under the SSP126 scenario, the suitable habitat area for Ph. chinensis increased significantly, and under the SSP585 scenario, the highly suitable areas transformed into extremely suitable areas, also showing substantial growth. Future global warming is conducive to the survival and reproduction of Ph. chinensis. From the 2050s to the 2090s, the highly suitable areas for Ph. chinensis in Gansu Province will be projected to expand northward. Under the SSP126 scenario, the suitable habitat area for Ph. chinensis in Gansu Province is expected to increase by 194.75% and 204.79% in the 2050s and 2090s, respectively, compared to that of the 1991 to 2020 period. Under the SSP370 scenario, the moderately and highly suitable areas will be projected to increase by 164.40% and 209.03% in the 2050s and 2090s, respectively, while under the SSP585 scenario, they are expected to increase by 195.98% and 211.66%, respectively. Conclusions The distribution of potential suitable habitats of Ph. sinensis gradually shifts with climatic changes. Intensified surveillance and management of Ph. sinensis is recommended in central and eastern parts of Gansu Province to support early warning of MT-ZVL.

Objective:
To investigate the function and potential mechanism of hepatocellular carcinoma(HCC) cells-derived extracellular nicotinamide phosphoribosyl transferase(eNAMPT) in the angiogenesis of human umbilical vein endothelial cells(HUVEC).
Methods:
The eNAMPT secretion of HCC cells were stimulated by hypoxia treatment and investigated the angiogenesis of HUVEC was investigated by tube formation assays. Transcriptomic RNA sequencing(RNA-seq) analyses of HUVEC under eNAMPT treatment were used to explore the mechanism of the effect of eNAMPT-insulin receptor(INSR) axis on angiogenesis. Western blot was used to detect the effects of eNAMPT-INSR axis on protein expression of HUVEC cells. qRT-PCR was used to detect the influence of eNAMPT-INSR axis on the expression of HUVEC intracellular related target genes.
Results:
ELISA and Western blot results showed that the protein level of eNAMPT in the culture supernatant of HCC cells increased significantly after hypoxia stimulation.In vitroangiogenesis assay results showed that eNAMPT significantly increased the nodules number and total length of tubes in HUVEC. The transcriptome sequencing results of HUVEC showed that eNAMPT, as an insulin analogue, participated in the regulation of biological processes such as cell migration and angiogenesis in HUVEC, and might promote angiogenesis by activating insulin-like signaling pathways. Western blot results showed that the eNAMPT-INSR axis affected p-AKT and p-ERK1/2 protein levels in PI3K-AKT and MAPK-ERK1/2 signaling pathways in HUVEC. qRT-PCR results showed that the eNAMPT-INSR axis affected the expression of angiogenesis related target genes MMP2, MMP9 and VEGF in HUVEC.
Conclusion
eNAMPT secreted by HCC cells promotes angiogenesis by binding INSR to activate the PI3K-AKT and MAPK-ERK1/2 signaling pathways.

BACKGROUND:At present,it is found that both Chinese medicine for activating blood circulation and removing blood stasis and platelet-rich plasma technology can repair damaged blood vessels,promote vascular regeneration,rebuild blood supply in the femoral head,restore normal blood supply,and further promote osteogenesis.Both of them have certain advantages in early intervention of steroid-induced necrosis of femoral head.It can also further understand the mechanism of blood activating and stasis removing herbs and platelet-rich plasma technology in improving steroid-induced necrosis of the femoral head,and provide new ideas for future treatment. OBJECTIVE:To review the research progress of the mechanism of the combination of blood activating and blood stasis removing herbs and platelet-rich plasma technology on steroid-induced necrosis of the femoral head according to the related literature at home and abroad. METHODS:PubMed,Web of Science,Metstr,CNKI and WanFang databases were searched for relevant articles."Traditional Chinese medicine,signal pathways,steroid induced necrosis of femoral head,vascular endothelial growth factor,platelet rich plasma"were used as the Chinese and English search terms separately.The time limit for searching the literature was from January 2000 to July 2022,and 75 related articles were finally included. RESULTS AND CONCLUSION:Both Chinese medicine for activating blood circulation and removing blood stasis and platelet-rich plasma technology have certain advantages in intervening the early stage of steroid-induced necrosis of femoral head.For traditional Chinese medicine,both single and compound drugs can effectively alleviate the further development of steroid-induced necrosis of the femoral head.The specific mechanism is as follows:(1)The traditional Chinese medicine for activating blood circulation and removing blood stasis has a significant anticoagulation effect,which can antagonize the abnormal(hypercoagulable)state of blood caused by hormone drugs,and further restore the normal blood supply in the femoral head.(2)Traditional Chinese medicine for activating blood circulation and removing blood stasis can repair damaged vascular endothelium,regenerate blood vessels and remodel blood supply in the femoral head by activating vascular endothelial growth factor.(3)The traditional Chinese medicine of promoting blood circulation and removing blood stasis has the obvious effect of removing blood stasis,which can reduce the accumulation of fat cells in the bone marrow cavity and relieve the pressure in the femoral head.(4)Traditional Chinese medicine for promoting blood circulation and removing blood stasis can regulate relevant signal pathways,maintain bone metabolism,promote the differentiation and balance of osteoblasts and osteoclasts,and effectively reduce steroid-induced necrosis of the femoral head.In addition,platelet-rich plasma contains a large amount of high concentration of cell growth factor,which plays a positive role in osteogenesis and vascular regeneration,and can also improve the abnormal state of the blood.Traditional Chinese medicine for activating blood circulation and removing blood stasis combined with platelet-rich plasma technology can play their biological roles,and the intervention effect is more significant.
