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.

Elderly patients with lung cancer have a significantly increased risk of perioperative cardiopulmonary complications due to physiological decline, high incidence of complications and reduced surgical tolerance, which directly affects postoperative recovery and long-term survival. Although the concepts of minimally invasive surgery and enhanced recovery after surgery have improved clinical outcomes, early recognition and intervention of postoperative complications in elderly patients remains a significant challenge in the field of thoracic surgery. By integrating recent literature and clinical practice, this paper systematically analyzes the pathophysiological mechanism and risk factors of perioperative cardiopulmonary complications in elderly patients with lung cancer, and discusses individualized intervention strategies based on risk stratification and multidisciplinary team, in order to provide theoretical basis and practical guidance for optimizing perioperative management and improving postoperative prognosis in elderly patients.

AIM To investigate the effects of Heixiaoyao Powder on neuroinflammation in APP/PS1 transgenic mice.METHODS The 16-week-old male APP/PS1 transgenic mice were randomly divided into the model group,the BBG group(P2X7R specific antagonist,30 mg/kg)and high,medium and low dose Heixiaoyao Powder groups of(22.10,11.05,5.53 g/kg),in contrast to the male C57BL/6J mice of the same age and the same strain of the blank groups,with 12 mice in each group.When normal saline by gavage was dosed upon the blank group and the model group,and the other groups were treated with corresponding drug by gavage.After 90 days of administration,the mice had their learning and memory ability detected by Morris water maze test;their hippocampal pathological changes observed with HE staining;their MyD88 expression detected by immunofluorescence staining;their hippocampal levels of pro-inflammatory factors(TNF-α,IL-6),anti-inflammatory factors(IL-10),ATP and amyloid protein β(Aβ)detected by ELISA;their hippocampal mRNA expressions of P2X7R,TLR4,MyD88 and NF-κB-P65 detected by RT-qPCR method;and their hippocampal protein expressions of P2X7R,TLR4,MyD88,NF-κB-P65 and p-NF-κB-P65 detected by Western blot.RESULTS Compared with the blank group,the model group demonstrated prolonged escape latency and reduced frequency in crossing platform(P＜0.01);decreased number of hippocampal neurons,deranged neurons,and darker cytoplasm staining;increased immunofluorescence expression of hippocampal MyD88(P＜0.01);decreased IL-10 level(P＜0.01);increased levels of TNF-α,IL-6,ATP and Aβ(P＜0.01);increased mRNA and protein expressions ofP2X7R,TLR4 and MyD88(P＜0.01),and increased protein expression of p-NF-κB-P65(P＜0.01).Compared with the model group,the groups intervened with Heixiaoyao Powder or BBG demonstrated shortened escape latency and increased frequency in crossing platform(P＜0.01);more number of neatly arranged hippocampal neurons;increased hippocampal IL-10 level(P＜0.01),decreased levels of TNF-α,IL-6,ATP and Aβ(P＜0.05,P＜0.01);decreased mRNA and protein expressions of P2X7R,TLR4 and MyD88(P＜0.05,P＜0.01);and decreased protein expression of p-NF-κB-P65(P＜0.05,P＜0.01).Except the low dose Heixiaoyao Powder group,the other treatment groups shared decreased immunofluorescence expression of MyD88(P＜0.05,P＜0.01).CONCLUSION Heixiaoyao Powder can significantly improve the learning and memory ability of APP/PS1 model mice,and its mechanism may lie in its function in alleviating cerebral neuroinflammation by reducing the abnormal Aβ aggregation via inhibiting the activation of ATP/P2X7R/NF-κB signaling pathway.

Aim To explore the effect mechanism of Jiangzhi Ligan decoction decoction treating non-alco-holic fatty liver disease(NAFLD),based on network pharmacology and molecular docking technology,com-bined with cell experiment verification.Methods The active ingredients and potential targets of JZLGD in the treatment of NAFLD were obtained from the network pharmacology-related database,and the"drug-ingredi-ent-target"relationship network map was constructed,and the intersection genes were enriched by GO and KEGG.And the core components and the core target of molecular docking.Then,HepG2 cells were induced by palmitic acid(PA)to establish NAFLD model,and the cytotoxicity of JZLGD drug-containing serum was detected by MTT.The levels of intracellular total cho-lesterol(TC)and triglycerides(TG)were measured by the kit.Lipid degeneration was detected by oil red O staining.The expressions of p62,a key target of au-tophagy,and microtubule-associated proteinlight-chain-3(LC3),AMPKα and p-AMPKα were detected by Western blot.AMPK inhibitor(compound C,CC)and autophagy inhibitor chloroquine(CQ)intervention groups were set up to detect intracellular TC and TG content,and further verify the efficacy and mechanism of JZLGD.Results A total of 64 active components of JZLGD were screened,involving 373 targets and 109 intersection targets with NAFLD.The first four core targets were INS,AKT1,TNF and PPARγ,respective-ly.KEGG analysis showed that JZLGD treatment of NAFLD mainly concentrated in insulin resistance,AMPK,mTOR,autophagy and other signaling path-ways.Molecular docking results showed that cryptotan-shinone,lotus leaf,quercetin,aloe emodin and other core components were well bound to core targets and autophagy related protein receptors.The results showed that JZLGD intervention could significantly decrease the contents of TG and TC in PA-induced HepG2 cells,down-regulate the expression of p62 protein,up-regulate the expression of LC3 Ⅱ protein,and increase the phosphorylation degree of AMPK.However,the in-tervention of CC and CQ largely reversed the effect of JZLGD on improving lipid accumulation.Conclusion JZLGD regulates AMPK signaling pathway to activate autophagy,thereby treating NAFLD.

Objective:To investigate the incidence and risk factors associated with poor healing in closed drainage incisions among elderly lung cancer patients(aged ≥65 years)undergoing thoracoscopic pulmonary resection.Methods:A retrospective cohort study was conducted involving 471 elderly lung cancer patients who underwent single utility port video-assisted thoracic surgery(VATS)pulmonary resection at Beijing Hospital from January 1, 2022, to December 31, 2023.Patients were categorized into'healed’and'poor healing’groups based on the development of grade B/C healing following the removal of the closed drainage tube.A comparative analysis of demographic characteristics, medical history, and perioperative parameters between the groups was performed.Multivariate logistic regression analysis was employed to identify independent risk factors for poor incision healing.Results:A total of 471 elderly lung cancer patients who underwent VATS lobectomy were enrolled, with a mean age of 71.16 ± 3.44 years. Among them, 200(42.46%)were male and 271(57.54%)were female.Among 471 patients, 101(21.44%)developed poor healing, all classified as grade B. Univariate analysis revealed statistically significant differences between the two groups regarding BMI( χ2=1.632, P=0.004), diabetes mellitus( χ2=1.558, P=0.004), prolonged drainage duration ( χ2=1.829, P=0.002), and the extent of pulmonary resection( χ2=2.571, P=0.042).Multivariate logistic regression analysis indicated that a BMI of ≥24 kg/m 2( OR=1.534, 95% CI: 1.191-3.289, P=0.033), drainage tube indwelling time exceeding 4 days postoperatively( OR=1.712, 95% CI: 1.014-3.791, P=0.036), and diabetes mellitus( OR=1.855, 95% CI: 1.418-4.015, P=0.002)were significant factors influencing poor wound healing, with statistically significant differences noted( P<0.05). Conclusions:BMI, prolonged drainage duration, diabetes mellitus, and the extent of pulmonary resection are independent risk factors for poor healing of closed drainage incisions in elderly lung cancer patients following VATS.Clinical strategies should prioritize the control of BMI, perioperative glycemic management, real-time monitoring of drainage, and timely removal of tubes to mitigate complications.
