Objective: To identify biomolecular markers closely related to the occurrence of kidney renal clear cell carcinoma (KIRC) and verify their expression levels in clinical samples. Methods: Stage Ⅰ KIRC mRNA sequencing data were obtained from The Cancer Genome Atlas (TCGA).Principal component analysis (PCA) was used for dimensionality reduction to screen differentially expressed genes (DEGs)，which then underwent GO and KEGG analyses.Weighted gene co-expression network analysis (WGCNA) was used to screen genes significantly related to KIRC，and a protein-protein interaction (PPI) network was constructed to screen hub genes.The diagnostic value of hub genes was evaluated with receiver operating characteristic (ROC) curve，and their prognostic value was analyzed using survival curve plots.The correlation between the mRNA expressions of hub genes and the pathological stages of KIRC was analyzed.Clinical samples of 20 patients with stage Ⅰ KIRC treated in our hospital were included，and the expressions of the hub genes in cancerous and adjacent tissues were detected with reverse transcription real-time quantitative polymerase chain reaction (RT-qPCR)，Western blotting，and enzyme-linked immunosorbent assay (ELISA). Results: A total of 8223 DEGs were screened out，including 4092 up-regulated ones and 4131 down-regulated ones.GO analysis showed that DEGs were related to bioadhesion，plasma membrane composition，and transporter activity.KEGG analysis showed that DEGs were related to pathways such as cell adhesion molecules，cytokine-cytokine receptor interactions，and interactions between viral proteins and cytokines and cytokine receptors.WGCNA analysis obtained 171 genes that were significantly related to stage Ⅰ KIRC.The hub gene，lymphocyte cytosolic protein 2 (LCP2)，screened out by the PPI network，was significantly related to stage Ⅰ KIRC.The area under the ROC curve was 0.96.The expression level was negatively correlated with the overall survival rate of patients.The expression of LCP2 was related to the stage and lymph node metastasis.Clinical verification showed that the mRNA and protein relative expressions of LCP2 in KIRC tissues were significantly higher than those in adjacent tissues (P<0.000 1). Conclusion: LCP2 is significantly up-regulated in stage Ⅰ KIRC tissues and can be used as a potential biomarker for the early diagnosis and treatment of KIRC.

Objective To investigate the epidemiological characteristics of dengue fever in Shenzhen City in 2024, so as to provide insights into formulation of the preventive and control measures for dengue fever. Methods The epidemiological data of dengue cases reported in Shenzhen City in 2024 were extracted from the China Disease Prevention and Control Information System and field epidemiological survey data of dengue fever in Shenzhen City, and the temporal, regional and population distributions of dengue fever cases, source of acquire dengue virus infections, disease diagnosis and treatment and outbreaks were analyzed. The dengue virus nucleic acid was tested and the serotypes of dengue virus were characterized using real-time quantitative reverse transcription PCR (RT-qPCR) assay, and the dengue virus gene was sequenced using next-generation sequencing (NGS). In addition, the surveillance on the density of Aedes albopictus was performed using Breteau index (BI) and mosquito oviposition index (MOI). Results A total of 1 735 dengue fever cases were reported in Shenzhen City in 2024, including 952 local cases and 783 imported cases. Most imported dengue fever cases acquired infections from eight cities of Foshan, Guangzhou, Zhongshan, Jiangmen, Dongguan, Zhaoqing, Huizhou, and Zhuhai in the Pearl River Delta region (664 cases, 84.8% of total imported cases) into Baoan, Longgang, and Nanshan districts. The epidemic exhibited an early onset and rapid progression, peaking during the period between September and November (1 632 cases, 94.1% of total cases), and dengue fever cases were distributed across 73 subdistricts in 10 districts, with most cases reported in densely populated central and western regions. The dengue fever cases had a male-to-female ratio of 1.9∶1.0, and a median age of 37 (21) years, with a higher median age among local cases than among imported cases [40 (20) years vs. 33(15) years; Z = -10.30, P < 0.05]. Housework, unemployment, workers, and business service were predominant occupations (1 405 cases, 81.0% of total cases), and there was a significant difference in the constituent ratio of occupations between local and imported cases (χ² = 92.30, P < 0.05). Among the 1 735 dengue fever cases, the median duration from onset to definitive diagnosis was 3.3 (2.9) days, and 1 686 cases (97.2%) were identified in healthcare facilities, with a low rate of hospitalization and isolation seen in 1 701 inpatients with available epidemiological data (485 cases, 28.5% of total inpatients). A total of 29 outbreaks of dengue fever occurred in Shenzhen City across 2024, which primarily in construction sites (27 outbreaks, 93.1% of total). Dengue virus type I was the dominant serotype causing dengue fever in Shenzhen City in 2024. Sequencing showed that the genomes of dengue virus from multiple dengue fever cases in Shenzhen City shared a high sequence homology with those from cities neighboring Shenzhen City, and there might be intra-city transmission of dengue virus among multiple construction sites in Shenzhen City. The Aedes albopictus density was significantly higher in Shenzhen City in 2024 than in 2023, peaking from May to September. The annual MOI values ranged from 0.9 to 14.0, and the BI values ranged from 0.6 to 6.0. Conclusions The overall epidemic of dengue fever was severe in Shenzhen City in 2024, which was greatly affected by case importation from neighboring cities, construction sites-centered local transmission, and the effectives of routine mosquito vector control was not satisfactory. Integrated dengue fever control measures should be implemented, focusing on regional joint prevention and control mechanisms, capacity building for mosquito vector control, addressing challenges in epidemic containment at construction sites, and strengthening case detection and management systems.

Objective To investigate the correlation between serum Sortilin(SORT)and insulin-like growth factor 1(IGF-1)levels and the occurrence and prognosis of cardiovascular disease(CVD)in maintenance hemodialysis(MHD)patients with end-stage renal disease(ESRD).Methods Eighty-four MHD patients with ESRD diagnosed and treated in the First People's Hospital of Kunshan from February 2017 to February 2018 were selected as the MHD group.With 5 years of follow-up,the MHD group was divided into the CVD group(n=35)and the non-CVD group(n=49)according to whether they had concurrent CVD,while 60 healthy individuals who underwent physical examination during the same period were used as the control group.Enzyme-linked immunosorbent assay was used to detect serum SORT and IGF-1 levels.Multivariate logistic regression analysis was conducted to investigate the influencing factors of CVD in MHD patients with ESRD.The predictive value of serum SORT and IGF-1 for CVD in MHD patients with ESRD was analyzed by the receiver operating characteristic curve.The correlation between serum SORT and IGF-1 levels and the survival rate of MHD patients with ESRD was analyzed by Kaplan-Meier survival analysis.Results Compared to the control group,the MHD group had higher serum SORT level(413.37±55.41 ng/L vs 81.27±24.69 ng/L)and lower serum IGF-1 level(117.64±18.42 μg/L vs 421.34±14.58 μg/L),with significant differences(t=43.416,106.122,all P＜0.001).The age,dialysis time,and serum SORT level(488.73±55.41ng/L vs 359.54±58.29ng/L)of patients in the CVD group were higher than those in the non-CVD group,while serum IGF-1 level(88.25±17.92 μg/L vs 138.63±19.55μg/L)was lower than that of the non-CVD group,with significant differences(t=2.896,2.588,10.221,12.050,all P＜0.05).Age(OR=1.548,P＜0.001),dialysis time(OR=1.616,P＜0.001)and serum SORT(OR=1.353,P＜0.001)were independent risk factors for CVD in MHD patients,while serum IGF-1(OR=0.742,P=0.000)was a protective factor for CVD in MHD patients.The area under the curve(95％CI)of the combined serum SORT and IGF-1 test for predicting concomitant CVD in MHD patients was 0.931(95％CI:0.895～0.961),which was greater than that of the single detection[0.843(0.810～0.889),0.887(0.833～0.921)],and the differences were statistically significant(Z=5.117,4.895,all P＜0.001).The five-year cumulative survival rate of MHD patients in the SORT high expression group(48.39％)was lower than that in the low expression group(84.81％),while the five-year cumulative survival rate of MHD patients in the IGF-1 low expression group(51.52％)was lower than that in the high expression group(84.31％),and the differences were significant(Log-Rank x2=18.670,8.900,all P＜0.01).Conclusion The serum SORT levels increased while IGF-1 levels decreased in MHD patients.The combined detection of the two has high predictive value for the occurrence of CVD in MHD patients with ESRD,which is associated with poor survival prognosis in MHD patients with ESRD.

Over the past decade, mitochondrial dysfunction has been investigated as a key contributor to acute and chronic kidney disease. However, the precise molecular mechanisms linking mitochondrial damage to kidney disease remain elusive. The recent insights into the cyclic guanosine monophosphate-adenosine monophosphate (GMP-AMP) synthetase (cGAS)-stimulator of interferon gene (STING) signaling pathway have revealed its involvement in many renal diseases. One of these findings is that mitochondrial DNA (mtDNA) induces inflammatory responses via the cGAS-STING pathway. Herein, we provide an overview of the mechanisms underlying mtDNA release following mitochondrial damage, focusing specifically on the association between mtDNA release-activated cGAS-STING signaling and the development of kidney diseases. Furthermore, we summarize the latest findings of cGAS-STING signaling pathway in cell, with a particular emphasis on its downstream signaling related to kidney diseases. This review intends to enhance our understanding of the intricate relationship among the cGAS-STING pathway, kidney diseases, and mitochondrial dysfunction.

Objective:To investigate the perinatal outcomes and risk factors of perinatal complications in preg-nant women with hypertrophic cardiomyopathy(HCM).Methods:A retrospective analysis was carried out on clini-cal data of 100 pregnant women with HCM who delivered in Obstetrical Cardiology Intensive Care Center of Shanghai Renji Hospital between Jan.2000 and Dec.2022.Analyze the incidence of perinatal complications inclu-ding miscarriage,premature birth,small for gestational age infants,neonatal asphyxia,neonatal cardiac malforma-tions and perinatal mortality.Independent risk factors of perinatal complications in pregnant women with HCM were identified using univariate and multivariate Logistic regression.Results:①The mean age was 29.21±4.41 years old,the average gestational age upon admission is 34.46±6.43 weeks.There were 16 patients with a fam-ily history of cardiomyopathy(16％),21 cases with obstructive HCM(21％)and 79 cases of non-obstructive HCM(79％),91 cases with abnormal ECG(91％),mainly with ST-T changes(77 cases,77％).The average in-terventricular septum was 19.39±6.13mm by echocardiography.②Among the 100 pregnancies of 100 HCM pa-tients,6 cases(6％)were miscarriages,94 newborns survived(94％),including 91 cases of cesarean section(91％)and 3 cases of vaginal delivery(3％).The predominant perinatal complications were preterm delivery(39 cases,39％),small for gestational age(5 cases,5％),neonatal asphyxia(3 cases,3％)and neonatal cardiac malformation(2 cases,2％).There were no perinatal deaths.③Univariate Logistic regression analysis showed that pre pregnancy heart function ≥ Grade Ⅱ,increased left atrial diameter,and concomitant pulmonary hyperten-sion were risk factors for perinatal complications in pregnant women with HCM(OR＞1,P＜0.05).Multivariate Lo-gistic regression analysis found that pre pregnancy heart function ≥ Grade Ⅱ was an independent risk factor for predicting the occurrence of perinatal complications in pregnant women with HCM(OR 6.270,P＜0.05).Conclu-sions:HCM during pregnancy can induce poor perinatal outcome.More attention should be paid to risk assess-ment and pregnancy management.Early detection of risk factors can reduce the incidence of perinatal complica-tions.
