Delirium is a common cause and complication of hospitalization in the elderly and is associated with higher risk of future dementia and progression of existing dementia, of which 70% is Alzheimer's disease (AD). AD and delirium, which are known to be aggravated by one another, represent significant societal challenges, especially in light of the absence of effective treatments. The intricate biological mechanisms have led to numerous clinical trial setbacks and likely contribute to the limited efficacy of existing therapeutics. Artificial intelligence (AI) presents a promising avenue for overcoming these hurdles by deploying algorithms to uncover hidden patterns across diverse data types. This review explores the pivotal role of AI in revolutionizing drug discovery for AD and delirium from target identification to the development of small molecule and protein-based therapies. Recent advances in deep learning, particularly in accurate protein structure prediction, are facilitating novel approaches to drug design and expediting the discovery pipeline for biological and small molecule therapeutics. This review concludes with an appraisal of current achievements and limitations, and touches on prospects for the use of AI in advancing drug discovery in AD and delirium, emphasizing its transformative potential in addressing these two and possibly other neurodegenerative conditions.

Aim To reveal the mechanism of cross-species ischemic heart failure from the perspective of spatial and gene co-expression networks.Methods GSE210374 and GSE57338 high-throughput sequencing datas were re-trieved from the national center for biotechnology information gene expression database(NCBI-GEO),and R language soft-ware packages was used to analyze and screen differentially expressed genes(DEG)in different myocardial regions of myo-cardial infarction rats,as well as DEG of myocardial samples from patients with ischemic heart failure and healthy controls,and the regional expression of common genes was analyzed.Weighted gene co-expression network analysis(WGCNA)was used to screen the genes related to myocardial infarction and to carry out enrichment analysis,protein-protein interac-tion network(PPI)was constructed to screen core genes(HG).Results A total of 4 835 differentially expressed genes were screened out in myocardial infarction rats and normal controls,and 51 differentially expressed genes were screened out in ischemic heart failure patients and normal control samples,which revealed representative gene sets in the left ventricular myocardial infarction area(I area),border area(BZ area),and remote area(R area)after myocardial in-farction.Spatial expression analysis revealed that there were 20 co-expressed genes in each myocardial region,16 of which were expressed in all three regions,the number of genes specifically expressed in I,BZ and R regions were 2,0 and 2,respectively.Enrichment analysis showed that the functions of co-expressed genes were different in different region.The I and BZ regions were related to collagen fiber assembly,stress-induced cardiomyocyte hypertrophy,down-regulation of c-Jun amino terminal kinase(JNK signal)and cell proliferation,and complement signaling pathways;The I and R regions were enriched in the binding of Wnt and collagen;As a non-ischemic distal R region,the co-expressed genes were signifi-cantly enriched in the extracellular matrix for functions such as compressive resistance,cytolysis and inhibition of T cell proliferation.Furthermore,it was worth noting that the products of co-expressed genes in the three regions were mostly lo-cated in the extracellular space and extracellular matrix,suggesting that there may be active cellular secretion and interac-tion regulation.Further PPI analysis suggested that asporin(ASPN),osteoglycin(OGN)and collagentype ⅩⅥ alpha chain(COL14A1)gene might be the core genes of the mechanism mentioned above.Conclusions The common mechanism of ischemic heart failure in rats and human involves multiple signaling pathways such as complement and coagu-lation cascade signaling and Wnt;which may be closely related to cell apoptosis mediated by extracellular matrix and exo-somes;ASPN,OGN,and COL14A1 may be the core genes.This work is expected to provide spatial and pathway refer-ence for the selection of intervention targets and pathway in the transformation research related to ischemic heart failure.

Objective:To evaluate the efficacy and safety of antaitasvir phosphate 100 mg or 200 mg combined with yiqibuvir for 12 weeks in patients with various genotypes of chronic hepatitis C, without cirrhosis or compensated stage cirrhosis.Methods:Patients with chronic hepatitis C (without cirrhosis or compensated stage cirrhosis) were randomly assigned to the antaitasvir phosphate 100 mg+yiqibuvir 600 mg group (100 mg group) or the antaitasvir phosphate 200 mg+yiqibuvir 600 mg group (200 mg group) in a 1∶1 ratio. The drugs were continuously administered once a day for 12 weeks and observed for 24 weeks after drug withdrawal. The drug safety profile was assessed concurrently with the observation of the sustained virological response (SVR12) in the two patient groups 12 weeks following the drug cessation. The intention-to-treat concept was used to define as closely as possible a full analysis set, including all randomized cases who received the experimental drug at least once. The safety set was collected from all subjects who received the experimental drug at least once (regardless of whether they participated in the randomization group) in this study. All efficacy endpoints and safety profile data were summarized using descriptive statistics. The primary efficacy endpoint was SVR12. The primary analysis was performed on a full analysis set. The frequency and proportion of cases were calculated in the experimental drug group (antaitasvir phosphate capsules combined with yiqibuvir tablets) that achieved "HCV RNA

Objective:To explore the feasibility and value of performing a three-sided encapsulation procedure based on fascia anatomy in laparoscopic lateral lymph node dissection (LLND) for middle and low rectal cancer.Methods:This was a retrospective review. The study cohort comprised patients who met the diagnostic criteria for rectal cancer according to the Chinese Guidelines for the Diagnosis and Treatment of Colorectal Cancer, had a short lymph node diameter of >5 mm on the lateral side within the 15 days before surgery, were evaluated as feasible candidates for laparoscopic total mesorectal excision+LLND surgery, had been diagnosed with low or intermediate level rectal cancer, and whose tumor was less than 8 cm away from the anal verge according to pathological examination of the operative specimen. Patients with a history of other malignant tumors of the abdomen or with incomplete follow-up data were excluded. Forty-two patients with middle and low rectal cancer who had undergone lateral lymph node dissection in diagnosis and treatment center of Gastrointestinal Cancer of Guangdong Hospital of Chinese Medicine from Jan.2018 to Dec.2022 were enrolled. There were 24 men (57.1%) and 18 women (42.9%) aged 58.4±11.8 years and the median BMI was 22.5 (19.3–24.1) kg/m 2. The main point of the three-sided encapsulation procedure is to expand the external side medial to the external iliac artery and vein, narrowing the range of exterior side dissection. The anterior-medial side is designed to expand the vesical fascia to define the range of anterior-medial side extension. The internal side is fully extended to the ureterohypogastric nerve fascia; the distal point of the caudal extension reaches the level of the Alcock canal and the bottom reaches the piriformis, enabling dissection of the obturator nerve and No.283 lymph nodes. No.263D lymph nodes are dissected by exposing the internal iliac artery and its branches, dissecting the group No.263P lymph nodes, and severing the inferior vesical artery. Finally, the lateral lymphatic tissue is completely resected. Relevant variables were recorded, including the number of lateral lymph nodes detected, the rate of lymph node metastasis, operation duration, intraoperative blood loss, postoperative complications, postoperative hospital stay, and 3-year overall survival rate. Results:Laparoscopic surgery was successfully completed in all patients with no conversions to open surgery and no intraoperative complications. Twenty-seven (64.3%) of the study patients underwent left-sided LLND, 10 (23.8%) right-sided LLND, and five (11.9%) bilateral LLND, with lymph nodes cleared on both sides. All patients' lymph nodes were examined pathologically. A median of 17.0 (11.7, 26.0) lymph nodes was detected, the median of lateral lymph nodes being 5.0 (2.0, 10.2). The median operation time was 254.5 (199.0, 325.2) minutes. The median intra-operative blood loss was 50.0 (30.0, 100.0) mL. All patients were diagnosed with adenocarcinoma by pathological examination of the operative specimen. Two patients developed postoperative intestinal obstruction, one lymphatic leakage, and one a perineal incision infection. There were no cases of anastomotic leakage. The median postoperative hospital stay was 6.0 (5.0, 7.0) days and the median follow-up time 23.5 (9.0, 36.7) months. During follow-up, three patients (7.1%) died of tumor recurrence and metastasis. Two (4.8%) experienced mild urinary dysfunction, and one (2.4%) had moderate postoperative erectile dysfunction. One patient (2.4%) was found to have prostate and lung metastases 3 month after surgery. The 3-year overall survival rate was 74.4%.Conclusions:Three sided encapsulation is a safe and feasible procedure for LLND, achieving accurate and complete clearance of lateral lymphatic tissue.

This study aimed to observe the protective effect of momordicine I, a triterpenoid compound extracted from momordica charantia L., on isoproterenol (ISO)-induced hypertrophy in rat H9c2 cardiomyocytes and investigate its potential mechanism. Treatment with 10 μM ISO induced cardiomyocyte hypertrophy as evidenced by increased cell surface area and protein content as well as pronounced upregulation of fetal genes including atrial natriuretic peptide, β-myosin heavy chain, and α-skeletal actin; however, those responses were markedly attenuated by treatment with 12.5 μg/ml momordicine I. Transcriptome experiment results showed that there were 381 and 447 differentially expressed genes expressed in comparisons of model/control and momordicine I intervention/model, respectively. GO enrichment analysis suggested that the anti-cardiomyocyte hypertrophic effect of momordicine I may be mainly associated with the regulation of metabolic processes. Based on our transcriptome experiment results as well as literature reports, we selected glycerophospholipid metabolizing enzymes group VI phospholipase A 2 (PLA2G6) and diacylglycerol kinase ζ (DGK-ζ) as targets to further explore the potential mechanism through which momordicine I inhibited ISO-induced cardiomyocyte hypertrophy.Our results demonstrated that momordicine I inhibited ISO-induced upregulations of mRNA levels and protein expressions of PLA2G6 and DGK-ζ. Collectively, momordicine I alleviated ISO-induced cardiomyocyte hypertrophy, which may be related to its inhibition of the expression of glycerophospholipid metabolizing enzymes PLA2G6 and DGK-ζ.

To explore the potential mechanism of frankincense volatile oil in the prevention and treatment of cardiac hypertrophy based on in vitro cell experiment and network pharmacology. METHODS: The anti-hypertrophic effect of frankincense volatile oil was investigated by isoproterenol induced H9c2 cardiomyocytes hypertrophy model. The active chemical components and targets of frankincense volatile oil and targets associated with cardiac hypertrophy were obtained by CNKI, Pubmed, Pubchem databases, etc. String database and Cytoscape 3.8.0 software were used to construct protein-protein interaction network (PPI) and a network of "drug-active component-key target-disease" of frankincense volatile oil in order to screen the key targets of frankincense volatile oil against cardiac hypertrophy. The fluorescent quantitative PCR experiments were performed to verify those key targets. Gene Ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway annotation analysis of key target genes were performed using David online analysis tool. RESULTS: In vitro cell experiments showed that frankincense volatile oil significantly inhibited the isoproterenol induced increases in cardiomyocytes surface area and protein synthesis, and upregulations of ANP and β-MHC mRNA. A total of 87 active components and 36 ingredient-disease targets of frankincense volatile oil were screened. Network analysis showed that ESR1, NOS3, PTGS2, TNF, MAPK14, and PPARG were key targets. Fluorescence quantitative PCR experiments results indicated that frankincense volatile oil inhibited isoproterenol induced upregulations of ESR1, PTGS2, TNF, and MAPK14 mRNA levels, and downregulations of NOS3, PPARG mRNA levels, respectively. In addition, the GO functional enrichment analysis showed that its biological pathways mainly included lipopolysaccharide-mediated signaling pathway, positive regulation of nitric oxide biosynthetic process, caveola, enzyme binding, etc. The KEGG pathway enrichment analysis included 22 KEGG pathways, which were closely related to VEGF signaling pathway, TNF signaling pathway, sphingolipid signaling pathway and others. CONCLUSION: The active components of frankincense volatile oil may regulate VEGF signaling pathway, TNF signaling pathway, Sphingolipid signaling pathway by acting on ESR1, NOS3, PTGS2, TNF, MAPK14 and PPARG targets, thereby affecting the regulation of lipopolysaccharide-mediated signaling pathway, positive regulation of nitric oxide biosynthetic process, caveola, and enzyme binding, and improving cardiac hypertrophy.
