Objective To investigate the global burden of visceral leishmaniasis (VL) from 1990 to 2021 and predict the trends in the burden of VL from 2022 to 2035, so as to provide insights into global VL prevention and control. Methods The global age-standardized incidence, prevalence, mortality and disability-adjusted life years (DALYs) rates of VL and their 95% uncertainty intervals (UI) were captured from the Global Burden of Disease Study 2021 (GBD 2021) data resources. The trends in the global burden of VL were evaluated with average annual percent change (AAPC) and 95% confidence interval (CI) from 1990 to 2021, and gender-, age-, country-, geographical area- and socio-demographic index (SDI)-stratified burdens of VL were analyzed. The trends in the global burden of VL were projected with a Bayesian age-period-cohort (BAPC) model from 2022 to 2035, and the associations of age-standardized incidence, prevalence, mortality, and DALYs rates of VL with SDI levels were examined with a smoothing spline model. Results The global age-standardized incidence [AAPC = -0.25%, 95% CI: (-0.25%, -0.24%)], prevalence [AAPC = -0.06%, 95% CI: (-0.06%, -0.06%)], mortality [AAPC = -0.25%, 95% CI: (-0.25%, -0.24%)] and DALYs rates of VL [AAPC = -2.38%, 95% CI: (-2.44%, -2.33%)] all appeared a tendency towards a decline from 1990 to 2021, and the highest age-standardized incidence [2.55/105, 95% UI: (1.49/105, 4.07/105)], prevalence [0.64/105, 95% UI: (0.37/105, 1.02/105)], mortality [0.51/105, 95% UI: (0, 1.80/105)] and DALYs rates of VL [33.81/105, 95% UI: (0.06/105, 124.09/105)] were seen in tropical Latin America in 2021. The global age-standardized incidence and prevalence of VL were both higher among men [0.57/105, 95% UI: (0.45/105, 0.72/105); 0.14/105, 95% UI: (0.11/105, 0.18/105)] than among women [0.27/105, 95% UI: (0.21/105, 0.33/105); 0.06/105, 95% UI: (0.05/105, 0.08/105)], and the highest mortality of VL was found among children under 5 years of age [0.24/105, 95% UI: (0.08/105, 0.66/105)]. The age-standardized incidence (r = -0.483, P < 0.001), prevalence (r = -0.483, P < 0.001), mortality (r = -0.511, P < 0.001) and DALYs rates of VL (r = -0.514, P < 0.001) correlated negatively with SDI levels from 1990 to 2021. In addition, the global burden of VL was projected with the BAPC model to appear a tendency towards a decline from 2022 to 2035, and the age-standardized incidence, prevalence, mortality and DALYs rates were projected to be reduced to 0.11/105, 0.03/105, 0.02/105 and 1.44/105 in 2035, respectively. Conclusions Although the global burden of VL appeared an overall tendency towards a decline from 1990 to 2021, the burden of VL showed a tendency towards a rise in Central Asia and western sub-Saharan African areas. The age-standardized incidence and prevalence rates of VL were relatively higher among men, and the age-standardized mortality of VL was relatively higher among children under 5 years of age. The global burden of VL was projected to continue to decline from 2022 to 2035.

Objective To investigate the effect of long non-coding RNA(lncRNA)macrophage migration inhibitory factor antisense RNA1(MIF-AS1)on the malignant biological behavior of prostate cancer(PC)cells by regulating the miR-423-5p/pyrroline-5-carboxylic acid reductase 1(PYCR1)axis.Methods PC3 cells were cultured in vitro to knock down the expression of MIF-AS1 or down-regulate the expression of miR-423-5p.The expression of MIF-AS1,miR-423-5p and PYCR1 mRNA in tumor tissues and adjacent tissues and cells of PC patients were detected.The cell proliferation,apoptosis,migration,and invasion were detected and the expression of PYCR1 protein was detected by Western blot.The relationships between miR-423-5p,IF-AS1 and PYCR1 were verified.Results The MIF-AS1 and PYCR1 mRNA were observed to be highly expressed in the tumor tissues,while miR-423-5p was lowly expressed.Silenced MIF-AS1 inhibited the proliferation,migration and invasion of PC3 cells and up-regulated miR-423-5p induced cell apoptosis(P<0.05).Inhibition of miR-423-5p expression reversed the inhibitory effect of silencing MIF-AS1 on malignant behavior of PC3 cells(P<0.05).miR-423-5p was correlated with MIF-AS1 and PYCR1 by targeted regulation.Conclusion Silencing MIF-AS1 may inhibit the expression of PYCR1 by up-regulating miR-423-5p,thereby inhibiting the malignant behavior of PC cells.

Objective To explore the effect of KIAA0753 on glucose and energy metabolism in mouse embryonic osteoblast precursor cell line MC3T3-E1.Methods The GSE182286 datasets of patients with Joubert syndrome acquired from the Gene Expression Comprehensive database were analyzed for the levels of gene expression.After the cells with KIAA0753 overexpression were constructed and the experiment were divided into the control group,the high glucose group and the high glucose+overexpression KIAA0753 group,Western blotting was used to determine the effect of KIAA0753 on MC3T3-E1 cells under high glucose condition by detecting the expression of the glucose metabolism-related proteins,such as glycogen synthase 1 (GYS1 ),glycogen phosphorylase L (PYGL ),glucose transporter type 4 (GluT4 ),phosphofructokinase muscle (PFKM),pyruvate dehydrogenase phosphatase 1 (PDP1 ),and acetyl-CoA carboxylase α(ACACA ),as well as the mitochondria function-associated proteins,including peroxisome proliferator-activated receptor-γcoactivator-1α(PGC-1α),nuclear respiratory factor 1 (NRF1 ),and mitochondrial transcription factor A (TFAM).The effect of KIAA0753 on the intermediates of glucose metabolism was analyzed by determining the contents of glycogen,glucose and lactic acid in the cell culture medium.Cellular immunofluorescence assay and adenosine triphosphate (ATP ) assay were employed to measure the mitochondrial activity and function impacted by KIAA0753 in the cells under high glucose condition.The effect of KIAA0753 on the proliferation of MC3T3-E1 cells under high glucose was detected by EdU staining. Results The expression of KIAA0753 protein was downregulated in patients with Joubert syndrome and in MC3T3-E1 cells under high glucose conditions (P<0.05).High glucose resulted in inhibited protein expression of GYS1,ACACA,PFKM,GluT4,PGC-1α,TFAM and NRF1,enhanced protein levels of PDP1 and PYGL,reduced glycogen generation and consumption of extracellular glucose,and promoted production of lactic acid (P<0.05 ).While,overexpression of KIAA0753 could attenuate the effect of high glucose,that is,up-regulating the protein expression levels of GYS1,ACACA,PFKM,GluT4,PGC-1α,TFAM and NRF1,suppressing those of PDP1 and PYGL,enhancing glycogen generation and consumption of extracellular glucose,and inhibiting production of lactic acid (P<0.05 ). What's more,the overexpression also could elevate the activity and membrane potential of mitochondria,and promote the ATP synthesis (P<0.05 )and cell proliferation (P<0.05)in MC3T3-E1 cells under high glucose.Conclusion KIAA0753 can promote glucose metabolism and improve mitochondrial activity and function in osteoblasts,consequently providing more energy to the body.

Background and Aims:In the era of minimally invasive surgery,the role of pancreatic tumor enucleation(PTE)in treating benign or low-grade malignant tumors is gaining attention.The Da Vinci robot offers advantages such as enhanced visualization and flexible instrument manipulation,which can ensure the safe implementation of PTE.However,whether robotic pancreatic tumor excision(RPTE)is superior to laparoscopic pancreatic tumor enucleation(LPTE)remains undetermined.Therefore,this study was performed to explore this aspect. Methods:The clinical data of 38 patients who underwent surgical treatment for benign or low-grade malignant tumors in the Third Xiangya Hospital of Central South University from April 2020 to May 2024 were collected.Among them,18 cases underwent RPTE(RPTE group),and 20 cases underwent LPTE(LPTE group).Relevant clinical variables were compared between the two groups,and subgroup comparisons were further conducted for patients with tumors in the head and neck/body/tail of the pancreas. Results:The average operative time for the entire group was 125 min,with an average intraoperative blood loss of 67.89 mL,and no C-grade pancreatic fistula occurred.The incidence rates of B-grade pancreatic fistula,postoperative bleeding,and readmission were 39.5%,21.1%,and 18.4%,respectively,with an average postoperative hospital stay of 11.44 d.Overall,the RPTE group had shorter operative time and less intraoperative blood loss than the LPTE group(both P<0.05).There were no statistically significant differences between the two groups regarding the incidence of B-grade pancreatic fistula,intraoperative bleeding,readmission rate,and postoperative hospital stay(all P>0.05).Subgroup analysis showed that for patients with head tumors,the RPTE group had shorter operative time,less intraoperative blood loss,and a lower incidence of postoperative bleeding than the LPTE group(all P<0.05).However,the differences in the incidence of B-grade pancreatic fistula,readmission rate,and postoperative hospital stay were not statistically significant(all P>0.05).In patients with neck/body/tail tumors,the RPTE group also had shorter operative time and less intraoperative blood loss(both P<0.05),but the differences in incidence of B-grade pancreatic fistula,incidence of postoperative bleeding,readmission rate,and postoperative hospital stay were not statistically significant(all P>0.05). Conclusion:Minimally invasive PTE for the treatment of benign or low-grade malignant pancreatic tumors is safe.Compared to LPTE,RPTE can significantly reduce operative time and intraoperative blood loss and shows certain advantages in reducing postoperative complications,particularly for patients with head tumors.However,the conclusion of this study needs to be confirmed by larger prospective studies.

Objective:To analyze the relationship between the high sensitivity C-reactive protein (hs-CRP) and anxiety levels in patients hospitalized with cardiovascular-related diseases and hypertension.Methods:A total of 221 patients hospitalized with cardiovascular-related diseases in the Fuwai Hospital were selected by a voluntary sampling method from September to December 2021. Participants were divided into hypertensive and non-hypertensive groups ( n=119 and n=102) based on the diagnosis of hypertension in their inpatient medical records. Anxiety levels were assessed using the Zung Self-Rating Anxiety Scale, and the levels of serum hs-CRP were estimated by automatic immunoanalyzer. Multivariate logistic regression was used to analyze the relationship between hs-CRP and anxiety. Results:In the hypertensive group, the risk of anxiety in patients with abnormal hs-CRP (>3 mg/L) was 4.239 times (95% CI: 1.569-11.748, P=0.005) higher than those in normal hs-CRP (≤3 mg/L). In turn, compared with patients without anxiety, those with anxiety had 3.878 times greater probability of experiencing abnormal hs-CRP (95% CI: 1.495-10.062, P=0.005), while those with mild anxiety and moderate to severe anxiety had 4.525 times (95% CI: 1.392-14.714, P=0.012) and 3.286 times (95% CI: 0.911-11.357, P=0.070) greater odds of experiencing abnormal hs-CRP, respectively. No similar significant association was seen in the non-hypertensive group. Conclusion:There is an interrelationship between elevated hs-CRP and anxiety in hospitalized patients with cardiovascular-related diseases and hypertension.
