Objective: To analyze the surveillance data of schistosomiasis and snail status in Jiaxing City, Zhejiang Province from 2001 to 2024, so as to provide the reference for prevention and control of schistosomiasis in jiaxing City. Methods: Data on schistosomiasis and snail surveillance in Jiaxing City from 2001 to 2024 were collected through schistosomiasis control work reports and the Zhejiang Provincial Schistosomiasis (Parasitic Diseases) Control Information Management System. These data included serological testing results, stool etiological examination (stool examination) results, area surveyed for snails, snail-infested areas, number of snail-positive frames, and number of live snails. Indicators, including the positive rate of serological testing, the positive rate of stool examinations, the rate of snail-positive frames, and the density of live snails were analyzed. The Prophet time series model was employed to forecast the schistosomiasis epidemic in Jiaxing City from 2025 to 2029. Results: A total of 636 493 serological testing were conducted in Jiaxing City from 2001 to 2024, with a positive rate of 1.532%, showing a decreasing trend (P<0.05). Among 7 582 stool examinations, positive cases were all imported, resulting in a positivity rate of 0.066%. During the same period, snail surveys covered a cumulative area of 30 545.999 hm2, with snail-infested areas totaling 69.355 hm2; no significant trend was observed (P>0.05). All snail habitats were identified as recurrent foci within hydrographic network regions, primarily distributed across Xiuzhou District, Nanhu District, Pinghu City, Jiashan County, and Tongxiang City, with snail-infested areas of 39.588, 12.538, 10.728, 4.315, and 2.186 hm2, respectively. From 2009 to 2024, a total of 35 692 134 frames of snails were surveyed, of which 16 543 were snail-positive, yielding a snail-positive frame rate of 0.046%. A total of 33 175 live snails were collected, with a mean density of 0.000 98 snails per frame. No infected Oncomelania snails were detected. The projection results indicated that from 2025 to 2029, the positive rate of serological testing rate in Jiaxing City would range between 0.253% to 0.389%, the snail-infested areas would range from 0.025 to 1.818 hm2, and the density of live snails would vary from 0.001 56 to 0.001 66 snails per frame. None of these indicators showed a significant trend (all P>0.05). Conclusions From 2001 to 2024, the positive rate of serological testing rate of schistosomiasis in Jiaxing City showed a declining trend, with no new autochthonous cases or infected Oncomelania snails detected. However, imported cases were still reported. All identified snail habitats were recurrent foci within hydrographic network regions. It is recommended to enhance schistosomiasis and snail status surveillance in high-risk areas.

Objective:To analyze the target signaling pathway of histone H3K27 methylation-induced podocyte injury, verify the regulatory effect of histone H3K27 methylation on podocyte injury in focal segmental glomerulosclerosis (FSGS) mice through target signaling pathway, and explore the mechanism of abnormal methylation of histone H3K27-induced podocyte injury in FSGS mice.Methods:(1) Cell experiments: primary cultured immortalized mouse podocytes MPC5 were cultured in vitro, and divided into control group, adriamycin (ADR) group, ADR+GSK-J4 (histone demethylase, KDM6B inhibitor) group, ADR+coumarin A1 (C-A1, JAK2 agonist) group and ADR+GSK-J4+C-A1 group. The transmission electron microscope was used to observe ultrastructure of podocytes. Immunofluorescence was used to detect the protein expression of H3K27me3 and nephrin in podocytes. The whole genome sequence of podocytes was obtained, the differentially expressed genes were screened, and Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) were used for enrichment analysis. Real time-quantitative PCR and Western blotting were used to detect the gene and protein expression of JAK2-STAT3 signaling pathway in podocytes respectively. Enzyme-linked immunosorbent assay was used to detect interleukin 6 (IL-6), monocyte chemotactic protein 1 (MCP-1), α-smooth muscle actin (α-SMA) and transforming growth factor β1 (TGF-β1). (2) Animal experiments: EZH2 gene knock out ( EZH2podKo)-FSGS (tail vein injection of ADR) mouse models were established, and divided into EZH2ctrl+control group ( n=20), EZH2ctrl+FSGS ( n=20), EZH2podKo+control group ( n=30) and EZH2podKo+FSGS group ( n=30). HE staining was used to observe the morphology of kidney tissues. Immunohistochemistry was used to detect the H3K27me3 protein expression in podocytes. Real time-quantitative PCR and Western blotting were used to verify the gene and protein expression of JAK2-STAT3 signaling pathway respectively. Enzyme-linked immunosorbent assay was used to detect IL-6, MCP-1, α-SMA and TGF-β1 of kidney tissues. Results:(1) Cell experiments: Compared with control group, the nucleus shrank and ruptured, the cytoplasm showed vacuole, and mitochondria and endoplasmic reticulum swelled in ADR group, which verified that the podocyte injury model of ADR nephropathy was successfully established. Compared with control group, the protein expression level of H3K27me3 in ADR group was significantly lower ( P<0.05). Compared with ADR group, the protein expression level of H3K27me3 in podocytes in ADR+GSK-J4 group was significantly higher ( P<0.05), and there were 502 increased genes and 443 decreased genes. GO enrichment analysis showed that the differentially enriched peaks were mainly in ribonucleoprotein complex biogenesis, ribosome biogenesis, establishment of protein localization to organelle, and involved in regulation of receptor signaling pathway via JAK-STAT and receptor signaling pathway via JAK-STAT. Differential expressed genes were Irf1, Tnfrsf1a, S ocs1, Notch1, Gadd45a, Hes1 and Socs3, involving in the regulation of JAK-STAT signaling pathway. KEGG enrichment analysis showed that the differentially enriched peaks were mainly in amyotrophic lateral sclerosis, and the target genes were Mcl1, Egfr, Socs1, Cdkn1a, Pdgfa and Socs3, involving in the regulation of JAK-STAT signaling pathway. Compared with ADR group, the mRNA and protein expression levels of JAK2 and STAT3 in the ADR+GSK-J4 group were significantly lower, and the downstream inflammatory factors of IL-6, MCP-1 and α-SMA were significantly higher (all P<0.05). Compared with ADR group, the protein expression level of nephrin in ADR+GSK-J4 group was higher ( P<0.05), and the protein expression level of nephrin in ADR+C-A1 group was lower ( P<0.05). Compared with ADR+GSK-J4 group, the protein expression level of nephrin in ADR+GSK-J4+C-A1 group was lower ( P<0.05). (2) Animal experiments: Compared with EZH2ctrl+FSGS group, EZH2podKo+FSGS group showed obvious renal tissue damage, matrix hyperplasia in mesangial area with massive homogeneous substance deposition, apoptosis and necrosis of renal tubular epithelial cells, obvious thickening and extensive fusion of glomerular epithelial cells, basement membrane collapse, and compression and narrowing of capillary structure. Compared with EZH2ctrl+FSGS group, the protein expression level of H3K27me3 in EZH2podKo+FSGS group was significantly lower, and the mRNA and protein expression levels of JAK2 and STAT3, and the levels of IL-6, MCP-1, α-SMA and TGF-β1 were higher (all P<0.05). Conclusions:Abnormal methylation modification of H3K27 leads to change of target gene expression, activation of JAK2-STAT3 signaling pathway, podocyte injury, glomerulosclerosis and renal tubular injury, participating in the development of FSGS.

Objective:To investigate the quantification assessment of segmental volume after thigh liposuction utilizing three-dimensional(3D) scanning technology.Methods:This retrospective study was performed with the analysis of 3D scanning images of patients who had undergone bilateral thigh liposuction in Body Contouring & Fat Grafting Center, Plastic Surgery Hospital, Chinese Academy of Medical Sciences from January 2018 to September 2022. Preoperative and postoperative 3D scanning were performed to build visual 3D models of bilateral thighs. From top to the bottom, bilateral thighs were segmented into seven sections with a space of 5 cm in acquired 3D model. Certain measurements and calculation of preoperative and postoperative volume and volume change rate of the overall thigh and each segment were conducted, to validate the efficiency of liposuction (EOL). Additionally, EOL of each thigh segment was computed and the symmetry of bilateral thighs was analyzed before and after surgery. The volume differences were computed using the paired Wilcoxon rank-sum test, and intraclass correlation coefficient (ICC) was exerted to assess the symmetry of bilateral thighs before and after surgery.Results:A total of 36 female patients were included in the study, with an age range of 18 to 49 years and a mean age of (28.6±7.6) years. Follow-up duration ranged from 23 to 1 133 days postoperatively, with a mean follow-up period of 274.7 days. The results of 3D scanning measurements indicated significant changes ( P<0.01) in both the overall volume of the thigh and the volumes of each segment before and after surgery. The highest volume change rate and EOL were observed in the uppermost segment, and the volumetric change rate and EOL exhibited a descending trend across the segments of the thigh from the uppermost to the lowermost segments. The ICC of the volume of each segment consistently surpassed 0.950 whether preoperatively or postoperatively, indicating a high level of symmetry between the bilateral thighs, and the ICC of overall volume showed a notable increase from 0.992 preoperatively to 0.997 postoperatively. Conclusion:3D scanning technology can be exerted to quantify the volume changes before and after thigh liposuction. This study provided quantitative and objective evidence to confirm the efficacy of thigh liposuction procedure, elucidating that the most significant liposuction effects observed in the uppermost segment of the thigh. Moreover, postoperative assessments reveal a further enhancement in bilateral thigh symmetry.

ObjectiveTo genotype Oncomelania hupensis， based on microsatellites， in different snail-bearing environments in Jiaxing City， Zhejiang Province， for population genetics analysis in order to explore the reasons and influencing factors for the existence or proliferation of snails and to provide scientific basis for effective monitoring and control of snails. MethodsA total of 90 snail samples from three populations were collected in Yaobang Village （YB） and Sanxing Village （SX） in Pinghu City， and Yunhe Farm （YH） in Xiuzhou District， all were selected for snail checking in key snail habitats of Jiaxing City in 2022. DNA of the snails was genotyped and analyzed for population genetics using nine microsatellite loci. ResultsA total of 84 alleles were observed， and the mean number of alleles （Na） was 7.889， 5.667， and 3.778 for YB， SX， and YH respectively； the number of effective alleles （NeA） was 4.807， 3.329， and 2.294， respectively； and the coefficients of inbreeding （F_IS） were 0.400， 0.377， and 0.493， respectively. Under the Infinite Allele Model （IAM）， the SX and YH might have a recent bottleneck. The NEstimator and LDNe software calculated effective population sizes （Ne） were above 31.9. AMOVA analysis showed that the variation of snails in the three populations mainly existed among individuals， accounting for 41.4% of the total variation. The value of the index of genetic differentiation between populations （F_ST） was 0.286， indicating a high degree of genetic differentiation. The results of the principal component analysis and phylogenetic tree were consistent， and the three populations were divided into two lineages， YB and SX were one lineage， and YH belonged to another independent lineage. Population history and dynamics analysis showed that the gene flow of the three populations was insufficient， population divergence history indicated that YH might have diverged from SX first， and YB was produced by the contact fusion of SX and YH. ConclusionThe genetic diversity of snail populations in Jiaxing City is generally low， and the snail populations are unstable， with a great degree of genetic differentiation and insufficient gene flow among populations. This study can provide a basis for evaluating the effectiveness of the control of the snail as well as monitoring the trend of the spread of the snail.
