Objective To examine the impact of extreme temperature and drought stress on the survival of Bulinus globosus, so as to provide the theoretical evidence for the genomic research of Bulinus in absence of reference genes. Methods B. globosus snail samples were collected from Kiwani Shehia in Pemba Island, Zanzibar, Tanzania, and offspring snails were obtained through laboratory breeding and reproduction. A total of 120 10-week-old B. globosus snails from the same generation were selected and randomly assigned into four groups, including the high-temperature drought (HD) group, normal temperature drought (D) group, low-temperature drought (LD) group, and the control (C) group, of 30 snails in each group. Snails in HD, D, and LD groups were placed in beakers containing dry soil at the bottom and subsequently housed in climate chambers at 35, 26 ℃, and 10 ℃, respectively, while snails in Group C were maintained in 500 mL petri dishes containing dechlorinated tap water at 26 ℃. Following 3 days of breeding, living snails in each group were collected, and soft tissues were dissected and isolated. Total RNA was extracted from snail soft tissues for library construction, followed by high-throughput sequencing on the Illumina HiSeq 4000 sequencing system. De novo transcriptome assembly was performed using the Trinity software, and the longest transcripts were selected as unigenes. Gene functional annotations of unigenes were conducted using the Diamond software against Gene Ontology (GO) knowledgebase, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway database, NCBI non-redundant (NR) protein sequences database, Protein Family (Pfam) database, and UniProtKB/Swiss-Prot (Swiss-Prot) knowledgebase. GO and KEGG enrichment analyses of differentially expressed genes (DEGs) were performed using the topGO and clusterProfiler software, respectively. In addition, four relevant genes were selected for validation using a real-time quantitative PCR (qRT-PCR) assay to verify the reliability of transcriptome sequencing results. Results Following 3 days of breeding, there were 7, 20, 28, and 30 survival B. globosus snails in HD, LD, D, and C groups, with corresponding survival rates of 23.33% (7/30), 66.67% (20/30), 93.33% (28/30), and 100.00% (30/30), respectively (χ2 = 52.72, P < 0.001). De novo transcriptome assembly generated 176 942 unigenes, with annotation rates of 0.98%, 13.49%, 26.46%, 12.48%, and 14.39% against GO knowledgebase, KEGG pathway database, NR protein sequences database, Pfam database, and Swiss-Prot knowledgebase, respectively. There were 33 up-regulated and 72 down-regulated genes in Group D, 483 up-regulated and 815 down-regulated genes in Group HD, and 245 up-regulated and 172 down-regulated genes in Group LD relative to in Group C. Following removal of overlapping genes across groups and unmatched genes, 11 candidate genes were identified. GO and KEGG analyses revealed 3 heat shock protein (HSP)-related DEGs in these 11 candidate genes, which were annotated as HSP12.2, HSP70, and HSP20 genes and were all significantly up-regulated in each treatment group. Three immune and nervous system-related DEGs were identified, and were all significantly down-regulated in each treatment group, which were involved in the neural cell adhesion molecule L1-like protein pathway, fibrinogen binding protein pathway, and leukocyte elastase inhibitor-like protein pathway. qRT-PCR assay quantified that the expression trends of four genes related to temperature and drought stress across different treatment groups were highly consistent with transcriptome sequencing data. Conclusion The survival rate of B. globosus significantly reduces under combined stresses of extreme temperature and drought, possibly due to an imbalance in its cellular homeostasis regulatory system.

OBJECTIVE To investigate the effect and mechanism of Jingangteng capsules in the treatment of non-alcoholic fatty liver disease (NAFLD). METHODS Thirty-two SD rats were randomly divided into normal group and modeling group. The modeling group was fed a high-fat diet to establish a NAFLD model. The successfully modeled rats were then randomly divided into model group, atorvastatin group[positive control, 2 mg/(kg·d)], and Jingangteng capsules low- and high-dose groups [0.63 and 2.52 mg/(kg·d)], with 6 rats in each group. The pathological changes of the liver were observed by hematoxylin-eosin staining and oil red O staining. Enzyme-linked immunosorbent assay was performed to determine the serum levels of triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), alanine transaminase (ALT), aspartate transaminase (AST), tumour necrosis factor-α (TNF-α), interleukin-1β (IL-1β), IL-6, IL-18. 16S rDNA amplicon sequencing and metabolomics techniques were applied to explore the effects of Jingangteng capsules on gut microbiota and metabolisms in NAFLD rats. Based on the E-mail:591146765@qq.com metabolomics results, Western blot analysis was performed to detect proteins related to the nuclear factor kappa-B (NF-κB)/NOD-like receptor family protein 3 (NLRP3) signaling pathway in the livers of NAFLD rats. RESULTS The experimental results showed that Jingangteng capsules could significantly reduce the serum levels of TG, TC, LDL-C, AST, ALT, TNF-α, IL-1β, IL-6, IL-18, while increased the level of HDL-C, and alleviated the hepatic cellular steatosis and inflammatory infiltration in NAFLD rats. They could regulate the gut microbiota disorders in NAFLD rats, significantly increased the relative abundance of Romboutsia and Oscillospira, and significantly decreased the relative abundance of Blautia (P<0.05). They also regulated metabolic disorders primarily by affecting secondary bile acid biosynthesis, fatty acid degradation, O-antigen nucleotide sugar biosynthesis, etc. Results of Western blot assay showed that they significantly reduced the phosphorylation levels of NF-κB p65 and NF-κB inhibitor α, and the protein expression levels of NLRP3, caspase-1 and ASC (P<0.05 or P<0.01). CONCLUSIONS Jingangteng capsules could improve inflammation, lipid accumulation and liver injury in NAFLD rats, regulate the disorders of gut microbiota and metabolisms, and inhibit NF-κB/NLRP3 signaling pathway. Their therapeutic effects against NAFLD are mediated through the inhibition of the NF-κB/NLRP3 signaling pathway.

Objective: To evaluate the efficacy and safety of the single-use hemoperfusion device (UA230) in treating refractory gout (RG) via plasma perfusion. Methods: Thirty-four RG patients aged 18-65 years were recruited and randomly divided into a control group (febuxostat therapy, n=17) and an experimental group (plasma perfusion combined with febuxostat therapy, n=17). Differences in serum uric acid (SUA) levels and urate-lowering rates between the two groups were analyzed using t-tests. Between-group differences in incidence of adverse reactions were analyzed using chi-square tests. Results: At 7 and 14 days post-treatment, SUA levels in the experimental group were significantly lower than those in the control group, with a higher urate-lowering rate (all P<0.05). However, no statistically significant differences in SUA levels or urate-lowering rate were observed at 28 days post-treatment (all P>0.05). The incidence of adverse reactions showed no significant difference between the two groups (χ
=0.15, P>0.05). Conclusion: The single-use hemoperfusion device (UA230), combined with plasma perfusion technology, is a safe and effective treatment for RG. It may serve as a novel therapeutic approach for RG patients in clinical practice.

Objective:To analyze the awareness of HCV infection status and willingness for HCV-RNA testing among hepatitis C cases in four provinces in China and to provide a reference for adjusting HCV prevention and control strategies.Methods:From September 2021 to September 2022, a cross-sectional survey was conducted using stratified random cluster sampling in four provinces (Jiangsu, Henan, Hubei, and Yunnan) in China, with an estimated sample size of 6 468 participants. The questionnaire included sociodemographic information, HCV infection awareness, willingness for HCV-RNA testing, and history of high-risk behaviors from the survey participants. Logistic regression models were used to analyze the factors associated with HCV infection awareness and willingness for HCV-RNA testing among hepatitis C cases. Statistical analysis was performed using R 4.1.3 software.Results:A total of 10 563 hepatitis C cases were surveyed. The awareness rate of HCV infection was 86.74% (9 162/10 563), and the willingness rate for HCV-RNA testing was 85.21% (9 001/10 563). Multivariate logistic regression models analysis showed that the awareness rate of HCV infection was lower among individuals aged ≥60 years, urban residents (with New Rural Cooperative Medical Insurance ), those without a history of blood transfusion, those without a history of paid blood donation, those without a history of injection drug use, and those without a family member with hepatitis C case.The awareness rate was higher among individuals with high or technical secondary school education, college education or above, and those married with a spouse (all P<0.05). In terms of willingness for HCV-RNA testing, it was lower among females, individuals aged ≥60 years, and those without a history of blood transfusion, paid blood donation, or injection drug use. The willingness was higher among farmers or migrant workers, employees of enterprises or institutions, and those in other occupations (all P<0.05). Conclusions:There was room for improvement in the awareness proportion of HCV infection and willingness for HCV-RNA testing among hepatitis C cases in the four provinces of China. More convenient policies and measures should be provided to increase the awareness rate of HCV infection and the willingness to undergo HCV-RNA testing in this population.
