ABSTRACT
Primary hyperparathyroidism is a disease with a large potential population. Some cases of primary hyperparathyroidism are non-primary, preventable and curable at early stage, requiring long-term follow-up after surgery. Therefore, all-round and full-cycle management are necessary for primary hyperparathyroidism, which involves an enhancing focus on etiological prevention, early detection, prompt diagnosis, timely intervention, multi-disciplinary standardized diagnosis and treatment, and postoperative scientific management. Meanwhile, implementing a "12+5+1" multidisciplinary joint diagnosis and treatment model, along with a two-way referral model, to achieve the transition from a disease-oriented diagnostic and treatment model to a patient-oriented, all-round and full-cycle interdisciplinary management model. This management can reduce the incidence and recurrence rate of primary hyperparathyroidism, and related osteoporosis or osteopenia, fractures, nephrolithiasis, metastatic vascular calcification, and systemic abnormal migratory calcium deposits, improve the overall quality of life and prognosis of patients.
ABSTRACT
The incidence of parathyroid hyperfunction is high and its clinical manifestations are diverse. Some patients develop chest tightness and palpitations as the main discomfort, which may be caused by the hypocalcemia and hypercalcemia related to negative calcium balance and parathyroid hyperfunction. We report a case of 53 years old male with parathyroid hyperfunction who was diagnosed with osteoporosis before and received conventional regular supplementation of vitamin D and calcium supplements. However, his condition worsened and he developed chest tightness and palpitation. After 1 month of sufficient supplementation of calcium, the symptoms of chest tightness and palpitation disappeared completely. Then we continued to provide the patients enough vitamin D and calcium supplementation actively. After 1 year of follow-up, the patient's condition was stable. His discomfort of chest tightness and palpitation never recurred, and all the bone metabolism indicators returned to normal.
ABSTRACT
@#Objective To investigate the role of cardiac rehabilitation program in the early recovery after minimally invasive incision coronary artery bypass grafting with general anesthesia. Methods A retrospective study was performed on the patients who underwent minimally invasive incision coronary artery bypass grafting from January 2015 to January 2020 with general anesthesia in our hospital. The patients were divided into a cardiac rehabilitation group and a control group. The clinical data of the patients were collected in 6 months and 12 months after the beginning of cardiac rehabilitation program and were analyzed by propensity score-matching analysis with a ratio of 1∶1. The main outcomes were the peak oxygen uptake (VO2 peak) of cardiopulmonary function test and the number of patients attending cardiovascular specialties in tertiary hospitals during the follow-up period (20 months). Results A total of 600 patients were enrolled, including 200 patients in the cardiac rehabilitation group [137 males and 63 females, aged 61.00 (56.00, 65.00) years] and 400 patients in the control group [285 males and 115 females, aged 60.00 (56.00, 65.00) years]. After matching, 176 patients were included in each group, and the basical clinical data of the pateints were comparable (P>0.05). The VO2 peak of the cardiac rehabilitation group after 6 months and 12 months of cardiac rehabilitation was significantly different from that of the control group [6 months: 1.96 (1.59, 2.38) L/min vs. 1.72 (1.38, 2.12) L/min, P<0.001; 12 months: 2.40 (2.21, 2.63) L/min vs. 2.12 (1.83, 2.45) L/min, P<0.001]. During the follow-up period, there was a statistical difference in the cardiovascular specialist visits in tertiary hospitals (P=0.004). Conclusion Cardiac rehabilitation program has a positive effect on the recovery of minimally invasive incision coronary artery bypass grafting with general anesthesia, and can improve the exercise ability of patients.
ABSTRACT
Background@#and Purpose The eye-movement examination can be applied as a noninvasive method to identify multiple-system atrophy (MSA). Few studies have investigated eye movements during the early stage of MSA with predominant parkinsonism (MSA-P). We aimed to determine the characteristic oculomotor changes in the early stage of MSA-P. @*Methods@#We retrospectively selected 17 patients with MSA-P and 40 with Parkinson’s disease (PD) with disease durations of less than 2 years, and 40 age-matched healthy controls (HCs).Oculomotor performance in the horizontal direction was measured in detail using videonystagmography. @*Results@#We found that the proportions of patients with MSA-P and PD exhibiting abnormal eye movements were 82.4% and 77.5%, respectively, which were significantly higher than that in the HCs (47.5%, p<0.05). Compared with HCs, patients with MSA-P presented significantly higher abnormal proportions of fixation and gaze-holding (17.6% vs. 0%), without-fixation (47.1% vs. 0%), prolonged latency in reflexive saccades (29.4% vs. 5.0%), memory-guided saccades (93.3% vs. 10.0%), and catch-up saccades in smooth-pursuit movement (SPM, 41.2% vs. 0) (all p<0.05). Compared with those with PD, patients with MSA-P presented a significantly higher proportion of catch-up saccades in SPM (41.2% vs. 2.5%, p<0.001). @*Conclusions@#MSA-P presented the characteristic of catch-up saccades in SPM in the early stage, which may provide some value in differentiating MSA-P from PD.
ABSTRACT
Cytomegalovirus(CMV)pneumonia is one of the common complications of hematopoietic stem cell transplantation,and is also a significant cause leading to patient death.Due to the poor prognosis of CMV pneumo-nia,intervention measures are necessary to prevent CMV reactivation and progress to CMV pneumonia.At present,clinical medication mainly relies on preemptive treatment strategies,and the timing of medication depends on the timeliness of early diagnosis.However,feasible methodology and measures for the early diagnosis of CMV pneumo-nia in clinical practice are relatively limited.Meanwhile the diagnostic gold standard operation is invasive,causing trauma to a certain degree,and the detection timeliness is poor.This review summarizes the clinical status and ad-vances in the diagnosis and drug prophylactic treatment of CMV pneumonia after hematopoietic stem cell transplan-tation,and explores possible development directions and trends in the future.
ABSTRACT
Objective To explore the efficacy and safety of recombinant human anti-severe acute respiratory syn-drome coronavirus 2(anti-SARS-CoV-2)monoclonal antibody injection(F61 injection)in the treatment of patients with coronavirus disease 2019(COVID-19)combined with renal damage.Methods Patients with COVID-19 and renal damage who visited the PLA General Hospital from January to February 2023 were selected.Subjects were randomly divided into two groups.Control group was treated with conventional anti-COVID-19 therapy,while trial group was treated with conventional anti-COVID-19 therapy combined with F61 injection.A 15-day follow-up was conducted after drug administration.Clinical symptoms,laboratory tests,electrocardiogram,and chest CT of pa-tients were performed to analyze the efficacy and safety of F61 injection.Results Twelve subjects(7 in trial group and 5 in control group)were included in study.Neither group had any clinical progression or death cases.The ave-rage time for negative conversion of nucleic acid of SARS-CoV-2 in control group and trial group were 3.2 days and 1.57 days(P=0.046),respectively.The scores of COVID-19 related target symptom in the trial group on the 3rd and 5th day after medication were both lower than those of the control group(both P＜0.05).According to the clinical staging and World Health Organization 10-point graded disease progression scale,both groups of subjects improved but didn't show statistical differences(P＞0.05).For safety,trial group didn't present any infusion-re-lated adverse event.Subjects in both groups demonstrated varying degrees of elevated blood glucose,elevated urine glucose,elevated urobilinogen,positive urine casts,and cardiac arrhythmia,but the differences were not statistica-lly significant(all P＞0.05).Conclusion F61 injection has initially demonstrated safety and clinical benefit in trea-ting patients with COVID-19 combined with renal damage.As the domestically produced drug,it has good clinical accessibility and may provide more options for clinical practice.

ABSTRACT
Objective To investigate the application of intravenous iron in patients with abnormal uterine bleeding(AUD)and iron deficiency anemia(IDA)in gynecology,to establish the drug utilization evaluation(DUE)standard,and to comprehensively evaluate the rationality of the clinical application of intravenous iron by analytic hierarchy process(AHP),so as to provide reference for the rational use of intravenous iron in clinical practice.Methods The medical records of patients with AUD and IDA from January to December 2022 in the First Affiliated Hospital of Anhui University of Science and Technology were collected,and the special rationality of the drug was evaluated from the aspects of indications,route and frequency of administration,daily dosage,solvent,combination medication,and contraindications of iron sucrose injection,and the DUE standard of the drug was formulated.AHP was used to analyze and evaluate 113 archived cases of intravenous iron in gynecology from January to December 2022.Results A total of 113 patients were treated with iron sucrose injection,and the indications,route of administration,solvent,contraindications,and allergic reactions were reasonable.The main unreasonableness was that the frequency of administration was inappropriate,the daily dose was inappropriate,the combination was not appropriate,the total iron supplement was not up to standard,and there was no continuous drug monitoring after medication.The case scores 90～100,70～<90 and 60～<70 were 6(5.31%),106(93.81%)and 1(0.88%),respectively.Conclusion Patients with AUD and IDA should pay attention to the dosage,total amount of iron supplementation,combined application of drugs and continuous medication monitoring after intravenous iron supplementation,so as to improve the rationality of their use.
ABSTRACT
Cells not only contain membrane-bound organelles (MBOs), but also membraneless organelles (MLOs) formed by condensation of many biomacromolecules. Examples include RNA-protein granules such as nucleoli and PML nuclear bodies (PML-NBs) in the nucleus, as well as stress granules and P-bodies in the cytoplasm. Phase separation is the basic organizing principle of the form of the condensates or membraneless organelles (MLOs) of biomacromolecules including proteins and nucleic acids. In particular, liquid-liquid phase separation (LLPS) compartmentalises and concentrates biological macromolecules into liquid condensates. It has been found that phase separation of biomacromolecules requires some typical intrinsic characteristics, such as intrinsically disordered regions, modular domains and multivalent interactions. The phase separation of biomacromolecules plays a key role in many important cell activities. In recent years, the phase separation of biomacromolecules phase has become a focus of research in gene transcriptional regulation. Transcriptional regulatory elements such as RNA polymerases, transcription factors (TFs), and super enhancers (SEs) all play important roles through phase separation. Our group has previously reported for the first time that long-term inactivation or absence of assembly factors leads to the formation of condensates of RNA polymerase II (RNAPII) subunits in the cytoplasm, and this process is reversible, suggesting a novel regulatory model of eukaryotic transcription machinery. The phase separation of biomacromolecules provides a biophysical understanding for the rapid transmission of transcriptional signals by a large number of TFs. Moreover, phase separation during transcriptional regulation is closely related to the occurrence of cancer. For example, the activation of oncogenes is usually associated with the formation of phase separation condensates at the SEs. In this review, the intrinsic characteristics of the formation of biomacromolecules phase separation and the important role of phase separation in transcriptional regulation are reviewed, which will provide reference for understanding basic cell activities and gene regulation in cancer.
ABSTRACT
ABSTRACT Purpose: To assess the effect of Amorphophallus campanulatus tuber (Ac) extract in the protection of diabetic nephropathy in streptozotocin (STZ) induced diabetic nephropathy (DN) rat model. Methods: Diabetes was induced with STZ (60 mg/kg, i.p.), and DN was confirmed after six weeks of STZ administration with the estimation of kidney function test. Further rats were treated with Ac 250 and 500 mg/kg p.o. for next four week. Oxidative stress and level of inflammatory cytokines were estimated in the kidney tissue of DN rats. Histopathology of kidney tissue was performed using hematoxylin and eosin staining. Results: There was improvement in the body weight of Ac treated groups than DN group of rats. Blood glucose level was observed to be reduced in Ac treated groups than DN group on 42nd and 70th day of protocol. Treatment with Ac ameliorated the altered level of kidney function tests (creatinine and BUN), enzymes of liver function (aspartate aminotransferase and alanine aminotransferase), and lipid profile in the serum of DN rats. Oxidative stress parameters (malondialdehyde and reactive oxygen species enhances and reduction in the level of glutathione and superoxide dismutase) and inflammatory cytokines such as interleukin-6, tumour necrosis factor-α, and monocyte chemoattractant protein-1 reduces in the tissue of Ac treated group than DN group. Treatment with Ac also attenuates the altered histopathological changes in the kidney tissue of DN rats. Conclusions: The report suggests that Ac protects renal injury in DN rats by regulating inflammatory cytokines and oxidative stress.
ABSTRACT
Chirality is one of the fundamental properties of nature, and most of the important molecules in living organisms contain chiral structures. The efficacy and safety of drugs are often closely related to the chiral structure of compounds, however, there are relatively more studies on synthetic characterization, pharmacology, and toxicology of chiral small molecule chemical drugs, but relatively less studies on chiral compounds contained in natural drugs such as traditional Chinese medicines. Chiral separation, as the basis of chiral research, has a pivotal position in the study of chiral compounds. In this paper, we systematically describe the separation methods of chiral compounds from the classification of chiral splitting methods based on chromatographic and non-chromatographic methods, as well as chromatographic packing materials, chiral additives and chiral derivatization, and review the chiral compounds in natural drugs such as traditional Chinese medicines reported in the past ten years, in order to provide references for the splitting and evaluating the activity of chiral compounds, and the improvement of quality standards of traditional Chinese medicines.
ABSTRACT
@#Abstract: Objective To analyze the influencing factors of mother-to-child transmission of hepatitis B virus after combined immunological blockade, and to evaluate the effect of mother-to-child blockade, and to provide a basis for health policies and health interventions for preventing mother-to-child blockade of hepatitis B virus. Methods A total of 11 363 pairs of HBsAg positive pregnant women and their infants aged 7-12 months in Hainan Province from 2015 to 2020 were included in the study. The general situation, the situation of health care and delivery in this pregnancy and perinatal period, the detection of hepatitis B markers, the situation of antiviral therapy, the general situation of mother and infant during delivery and the implementation of blockade measures for mother-to-child transmission of hepatitis B were collected and analyzed. Results Among the 11 363 pairs of HBsAg positive pregnant women and their infants delivered in hospitals in Hainan province from 2015 to 2020, the positive rate of HBsAg in children at 7-12 months after birth was 1.47 %, and the difference in HBsAg positive rate of infants born in different years was not statistically significant (P>0.05). There were no significant differences in the positive rate of HBsAg among children born to pregnant women with different nationalities, educational levels, occupations, delivery modes, delivery places, obstetric operations and perineal laceration, abnormal perinatal period, children with different genders and premature delivery and perinatal (all P<0.05). There was significant difference in HBsAg positive rate among infants born to pregnant women of different ages, the positive rate of HBsAg of infants born to young pregnant women was higher than that of older pregnant women (P<0.05). The rate of antiviral therapy was low in HBeAg positive pregnant women, and the positive rate of HBsAg in their infants was 2.54%, which was higher than 0.83% in HBeAg negative pregnant women (P<0.05). Conclusions Combined immunological blockade with hepatitis B vaccine and hepatitis B immunoglobulin can effectively prevent the mother-to-child transmission of HBV. HBsAg-positive women can give birth at the right age, and HBeAg-positive pregnant women can be treated with antiviral therapy to block mother-to-child transmission, providing the important basis for the formulation of hepatitis B prevention and control strategies and measures.
ABSTRACT
In clinical, manually scoring by technician is the major method for sleep arousal detection. This method is time-consuming and subjective. This study aimed to achieve an end-to-end sleep-arousal events detection by constructing a convolutional neural network based on multi-scale convolutional layers and self-attention mechanism, and using 1 min single-channel electroencephalogram (EEG) signals as its input. Compared with the performance of the baseline model, the results of the proposed method showed that the mean area under the precision-recall curve and area under the receiver operating characteristic were both improved by 7%. Furthermore, we also compared the effects of single modality and multi-modality on the performance of the proposed model. The results revealed the power of single-channel EEG signals in automatic sleep arousal detection. However, the simple combination of multi-modality signals may be counterproductive to the improvement of model performance. Finally, we also explored the scalability of the proposed model and transferred the model into the automated sleep staging task in the same dataset. The average accuracy of 73% also suggested the power of the proposed method in task transferring. This study provides a potential solution for the development of portable sleep monitoring and paves a way for the automatic sleep data analysis using the transfer learning method.

NDFIP1 has been previously reported as a tumor suppressor in multiple solid tumors, but the function of NDFIP1 in NSCLC and the underlying mechanism are still unknown. Besides, the WW domain containing proteins can be recognized by NDFIP1, resulted in the loading of the target proteins into exosomes. However, whether WW domain-containing transcription regulator 1 (WWTR1, also known as TAZ) can be packaged into exosomes by NDFIP1 and if so, whether the release of this oncogenic protein via exosomes has an effect on tumor development has not been investigated to any extent. Here, we first found that NDFIP1 was low expressed in NSCLC samples and cell lines, which is associated with shorter OS. Then, we confirmed the interaction between TAZ and NDFIP1, and the existence of TAZ in exosomes, which requires NDFIP1. Critically, knockout of NDFIP1 led to TAZ accumulation with no change in its mRNA level and degradation rate. And the cellular TAZ level could be altered by exosome secretion. Furthermore, NDFIP1 inhibited proliferation in vitro and in vivo, and silencing TAZ eliminated the increase of proliferation caused by NDFIP1 knockout. Moreover, TAZ was negatively correlated with NDFIP1 in subcutaneous xenograft model and clinical samples, and the serum exosomal TAZ level was lower in NSCLC patients. In summary, our data uncover a new tumor suppressor, NDFIP1 in NSCLC, and a new exosome-related regulatory mechanism of TAZ.

Metastatic vascular calcification and calcinosis universalis, as severe complications of parathyroid hyperfunction and hyperparathyroidism, have attracted more attention in patients with renal secondary hyperparathyroidism and primary hyperparathyroidism. But, they are of little concern in patients with long-term negative calcium balance related parathyroid hyperfunction or hyperparathyroidism caused by calcium and/or vitamin D insufficiency (CVI). CVI is common in the population. Relatively low level of serum calcium and negative calcium balance caused by long-term CVI result in parathyroid hyperfunction or hyperparathyroidism, which may cause secretion of PTH beyond the physiological level, leading to bone absorption and release of a large amount of bone calcium into the blood. It may not only cause bone loss and osteoporosis, but also form metastatic vascular calcification or calcinosis universalis presented by cardiovascular diseases and other multi-organ lesions. Early calcium deposition can gradually fade after reasonable treatment, but middle arterial calcification is not easy to fade once it occurs. Therefore, vascular calcification and calcium deposition should be actively prevented and early screened and diagnosed. The early prevention, diagnosis and treatment of parathyroid hyperfunction or hyperparathyroidism can prevent, delay, or even reverse the occurrence and development of metastatic vascular calcification and calcinosis universalis, which is significant for disease prevention and protecting the patients' health influenced by these diseases.

Data extraction, and literature quality evaluation were performed by two researchers independently, RevMan 5.3 was used for meta-analysis. Results:A total of 5 articles including 502 patients were included. The results showed that the closed oxygen therapy system could significantly improve the percentage of time within SpO 2 target of patients ( SMD=1.56, 95% CI 1.22-1.90, Z=9.04, P<0.001) and reduce the percentage of time with hypoxaemia ( SMD=-0.35, 95% CI-0.50--0.19, Z=4.37, P<0.001) or hyperoxia ( SMD=-0.91, 95% CI-1.07--0.75, Z=11.04, P<0.001) of patients. Moreover, the mean oxygen flow rate of closed oxygen therapy ( SMD=-0.64, 95% CI-1.25--0.03, Z=2.07, P<0.05), the mean oxygen therapy days ( SMD=-0.55, 95%, CI-1.06--0.03, Z=2.08, P<0.05), as well as the length of hospital stay ( SMD=-1.68, 95% CI-2.22--1.14, Z=6.11, P<0.001) were lower than those of patients with manual adjustment systems. Conclusion:The closed oxygen therapy system can promote the safety of oxygen use, but it needs clinical application to further explore.
ABSTRACT
Objective:To analyze the epidemic status and spatial and temporal cluster distribution of visceral leishmaniasis (VL) in Gansu Province, and to provide evidence for making precise prevention and control measures and epidemic surveillance.Methods:The data of VL cases in Gansu Province reported in the China Disease Prevention and Control Information System Infectious Disease Reporting Information Management System from 2015 to 2021 were collected, descriptive epidemiology analysis was performed (three distribution of the disease). SaTScan v9.6 and ArcMap 10.7 were used for spatio-temporal cluster analysis.Results:A total of 368 VL cases were reported from 2015 to 2021, 89.13% (328/368) were concentrated in Longnan City and Gannan Tibetan Autonomous Prefecture. The number of VL cases increased year by year from 2015 to 2017, reaching a peak in 2017 (79 cases, accounting for 21.47%), and had decreased year by year since 2018. There were cases every month throughout the year, and the peak was in April in spring (38 cases). The ratio of male to female patients was 1.3 ∶ 1.0 (208/160). Scattered children aged less than 5 years old were more common (41.30%, 152/368). The spatio-temporal cluster analysis showed that both the spatial and temporal aggregation zones of VL in Tanchang County and Chengxian County were of statistical significance ( P < 0.05). Conclusion:The incidence of VL in Gansu Province is showing a low epidemic trend, having spatio-temporal aggregation, and precise monitoring and prevention and control should be strengthened in epidemic areas with different prevalence levels.
ABSTRACT
Objective:To study the main blood parameters of Leishmania-infected dogs with different clinical symptoms in the high incidence area of visceral leishmaniasis in Gansu Province, and to provide scientific basis for early diagnosis and monitoring of canine leishmaniasis. Methods:In May 2019, Wenxian County of Longnan City and Diebu County of Gannan Tibetan Autonomous Prefecture, the historical endemic areas of visceral leishmaniasis in Gansu Province, were selected as the investigation sites, and 40 dogs with positive Leishmania DNA were investigated. According to their clinical symptoms, they were divided into three groups: asymptomatic ( n = 17), minimally symptomatic ( n = 12) and symptomatic ( n = 11). At the same time, 10 healthy dogs were selected as controls. Major blood indexes were detected by an automatic animal blood five-classification cell analyzer.

The above blood indexes were lower in the symptomatic group than those in the asymptomatic group. The number of red blood cells (control group vs symptomatic group) decreased from (6.82 ± 0.05) × 10 12/L to (4.19 ± 0.08) × 10 12/L, hemoglobin content decreased from (15.84 ± 0.74) g/L to (9.65 ± 0.18) g/L, hematocrit decreased from (46.41 ± 0.95)% to (27.86 ± 0.42)%, the number of white blood cells decreased from (14.90 ± 0.22) × 10 9/L to (10.23 ± 0.24) × 10 9/L, the number of neutrophils decreased from (7.25 ± 0.18) × 10 9/L to (6.18 ± 0.11) × 10 9/L, the number of lymphocytes decreased from (2.80 ± 0.07) × 10 9/L to (1.64 ± 0.06) × 10 9/L, the number of monocytes decreased from (1.13 ± 0.01) × 10 9/L to (0.53 ± 0.02) × 10 9/L, and the number of eosinophils decreased from (1.70 ± 0.06) × 10 9/L to (0.71 ± 0.03) × 10 9/L. Conclusion:Different clinical symptoms of Leishmania-infected dogs have different blood test results.
ABSTRACT
Objective:To investigate the clinical effect of dapagliflozin combined with metformin on type 2 diabetes mellitus (T2DM).Methods:A total of 100 patients with T2DM who received treatment in The Second People's Hospital of Hefei from June 2019 to May 2021 were included in this study. They were randomly divided into a control group ( n = 50) and an experimental group ( n = 50). The control group was treated with metformin, and the experimental group was treated with dagglitazin combined with metformin. All patients were treated for 3 months. Blood glucose index, blood lipid level, and the incidence of adverse reactions were compared between the two groups. Results:After treatment, fasting blood glucose, 2-hour post-prandial blood glucose, and glycosylated hemoglobin in the experimental group were (5.56 ± 0.37) mmol/L, (8.32 ± 0.23) mmol/L, and (6.17 ± 0.26)% respectively, which were significantly lower than (6.96 ± 0.48) mmol/L, (9.58 ± 0.39) mmol/L, and (7.27 ± 0.26)% respectively in the control group ( t = 3.59, 6.92, 5.03, all P < 0.05). The total cholesterol and triglyceride in the experimental group were (3.58 ± 0.53) mmol/L and (1.25±0.26) mmol/L, respectively, which were significantly lower than (4.94 ± 0.58) mmol/L and (1.93 ± 0.18) mmol/L in the control group ( t = 3.16, 4.25, both P < 0.05). There was no significant difference in the incidence of adverse reactions between the two groups ( P > 0.05). Conclusion:Dapagliflozin combined with metformin can effectively control blood glucose and blood lipid in T2DM patients without increasing adverse reactions.
ABSTRACT
Objective:To analyze and predict the transmission risk of visceral leishmaniasis in Gansu Province based on an ecological niche model, providing a basis for the development of precise prevention and control measures and epidemic surveillance.Methods:The information of reported cases of visceral leishmaniasis in Gansu Province from 2015 to 2021 were collected from the National Infectious Disease Reporting Information Management System, and the longitude and latitude coordinates of the distribution points of cases and the data of 19 climate variables, 5 geographical variables and 2 socio-economic variables within the region were obtained. Based on an ecological niche model, a model for predicting the transmission risk of visceral leishmaniasis was constructed using the maximum entropy algorithm (MaxEnt), and its performance was evaluated by the area under the receiver operating characteristic curve (AUC). Then the importance of each environmental variable of the model was evaluated, and the distribution area of visceral leishmaniasis transmission risk in Gansu Province was predicted.Results:A total of 368 cases of visceral leishmaniasis were reported in Gansu Province from 2015 to 2021, of which 89.13% (328/368) were from Longnan City and Gannan Tibetan Autonomous Prefecture (Gannan Prefecture). The number of cases peaked in 2017 (79 cases, 21.47%). The model had high prediction accuracy (AUC = 0.985). The results of model analysis showed that the important climate variable affecting the distribution of visceral leishmaniasis was the average temperature in the coldest quarter (contribution value of 3.1), the geographical variables were land use type (contribution value of 52.6) and vegetation cover type (contribution value of 8.5), and the socio-economic variable was population size (contribution value of 14.3). The distribution results of transmission risk showed that high, medium and low risk areas exhibited a gradual transition from the southern part to the northwest part of Gansu Province. The high risk areas were mainly located in the central and southern parts of Longnan City and the southern part of Gannan Prefecture, accounting for 0.18% of the total area of the province. Medium and low risk areas accounted for 0.48% and 2.47% of the total area of the province, respectively; and areas with no risk accounted for 96.87%.Conclusions:The ecological niche model predicts that the spread of visceral leishmaniasis in Gansu Province is characterized by point like dispersion and local high aggregation distribution. It is necessary to strengthen monitoring and prevention and control of high-risk areas such as Longnan City and Gannan Prefecture.
