Objective To explore the correlation between lymph node metastasis and clinicopathological features of lung adenocarcinoma with diameter≤3 cm. Methods The clinicopathologic data of the patients with lung adenocarcinoma≤3 cm in diameter were retrospectively analyzed. The relationship between lymph node metastasis and age, gender, smoking history, pathological subtype, tumor diameter, pleural invasion, vascular invasion and other factors was analyzed. The risk factors of lymph node metastasis were analyzed by univariate and multivariate logistic regression. Results Finally 1 718 patients were collected, including 697 males and 1 021 females with an average age of (58.89±9.85) years. The total lymph node metastasis rate was 12.9%, among whom 452 patients of adenocarcinoma in situ and minimally invasive adenocarcinoma did not have lymph node metastasis, and the lymph node metastasis rate of invasive lung adenocarcinoma was 17.5%. Multivariate analysis showed that tumor diameter, micropapillary subtype, solid subtype, micropapillary component, solid component, vascular invasion and pleural invasion were independent risk factors for lymph node metastasis of invasive lung adenocarcinoma with diameter≤3 cm (P<0.05). While age, lepidic subtype and lepidic component were independent protective factors for lymph node metastasis (P<0.05). Conclusion Clinicopathological features can help predict lymph node metastasis of lung adenocarcinoma with diameter≤3 cm.

OBJECTIVE: To observe the effect of electroacupuncture combined with enhanced recovery after surgery (ERAS) protocol on promoting intestinal function in patients after gastric cancer surgery. METHODS: Forty-four patients who underwent radical gastrectomy for gastric cancer were randomly divided into an experimental group (22 cases, 3 cases were excluded) and a control group (22 cases, 4 cases were excluded). Both groups received treatment under ERAS protocol, the experimental group was given electroacupuncture at bilateral Neiguan (PC6), Hegu (LI4), Zusanli (ST36) and Quchi (LI11), disperse-dense wave was selected, with frequency of 2 Hz/100 Hz. The control group received placebo electroacupuncture intervention, with the same acupoints as the experimental group, electrode pads were placed on the acupoints without electrical stimulation. Each session lasted 30 min, starting from 1 h after surgery, once every 24 h, until the patient resumed anal flatus. The intestinal sound rate of both groups was observed 24 h before surgery and 24, 48 h after surgery. The bowel sound recovery time (BSRT), time to first anal flatus, time to first defecation, and tolerance to oral enteral nutrition suspension were compared between the two groups. The levels of serum C-reactive protein (CRP), interleukin (IL)-2, IL-4, IL-6, IL-10, IL-12, IL-17, tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) were measured 24 h before surgery and 24 h after surgery in both groups. RESULTS: The intestinal sound rate 24 h after surgery was decreased compared with that 24 h before surgery in the two groups (P<0.05), the intestinal sound rate 24, 48 h after surgery in the experimental group was higher than that in the control group (P<0.05). The BSRT in the experimental group was earlier than that in the control group (P<0.05) .The levels of serum CRP, IL-6, IL-10 24 h after surgery in the experimental group were higher than those 24 h before surgery (P<0.05), while the levels of serum CRP, IL-4, IL-6, IL-10, IFN-γ in the control group were higher than those 24 h before surgery (P<0.05); the levels of serum CRP、IL-4、IFN-γ 24 h after surgery in the experimental group were lower than those in the control group (P<0.05) .The tolerance rate of oral enteral nutrition suspension in the experimental group was 84.2% (16/19), which was higher than 50.0% (9/18) in the control group (P<0.05). CONCLUSION Electroacupuncture combined with ERAS protocol can improve the intestinal motility, shorten the BSRT, enhance the tolerance of oral intake, and reduce inflammatory response in patients after gastric cancer surgery.

BACKGROUND: The transcription factor POU2F1 regulates the expression levels of microRNAs in neoplasia. However, the miR-29b1/a cluster modulated by POU2F1 in gastric cancer (GC) remains unknown. METHODS: Gene expression in GC cells was evaluated using reverse-transcription polymerase chain reaction (PCR), western blotting, immunohistochemistry, and RNA in situ hybridization. Co-immunoprecipitation was performed to evaluate protein interactions. Transwell migration and invasion assays were performed to investigate the biological behavior of GC cells. MiR-29b1/a cluster promoter analysis and luciferase activity assay for the 3'-UTR study were performed in GC cells. In vivo tumor metastasis was evaluated in nude mice. RESULTS: POU2F1 is overexpressed in GC cell lines and binds to the miR-29b1/a cluster promoter. POU2F1 is upregulated, whereas mature miR-29b-3p and miR-29a-3p are downregulated in GC tissues. POU2F1 promotes GC metastasis by inhibiting miR-29b-3p or miR-29a-3p expression in vitro and in vivo . Furthermore, PIK3R1 and/or PIK3R3 are direct targets of miR-29b-3p and/or miR-29a-3p , and the ectopic expression of PIK3R1 or PIK3R3 reverses the suppressive effect of mature miR-29b-3p and/or miR-29a-3p on GC cell metastasis and invasion. Additionally, the interaction of PIK3R1 with PIK3R3 promotes migration and invasion, and miR-29b-3p , miR-29a-3p , PIK3R1 , and PIK3R3 regulate migration and invasion via the phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR) pathway in GC cells. In addition, POU2F1 , PIK3R1 , and PIK3R3 expression levels negatively correlated with miR-29b-3p and miR-29a-3p expression levels in GC tissue samples. CONCLUSIONS The POU2F1 - miR-29b-3p / miR-29a-3p-PIK3R1 / PIK3R1 signaling axis regulates tumor progression and may be a promising therapeutic target for GC.

Objective:To screen the key genes related to the prognosis,diagnosis,and immune infiltration of the hepatocellular carcinoma(HCC)patients by bioinformatics analysis methods,and to analyze their potential therapeutic drugs.Methods:The HCC gene expression profile data and corresponding clinical informations of the HCC patients were downloaded from the Gene Expression Omnibus(GEO)database and The Cancer Genome Atlas(TCGA)database.The R software package limma was used to screen the differentially expressed genes(DEGs)in HCC.Gene Ontology(GO)functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis were performed on the DEGs.The STRING database was used to construct the protein-protein interaction(PPI)network;the Cytoscape software was used to visualize the PPI network and screen the key genes;Kaplan-Meier survival curve and LASSO regression algorithm were used to identify the key genes related to the HCC prognosis;external data sets were used to validate their expressions and analyze the diagnostic efficacy;CIBERSORT algorithm was used to detect the relationship between the expression of prognosis-related key genes and HCC immune cell infiltration.The MiRNet and Network Analyst databases were used to construct the microRNA(miRNA)-key gene mRNA and transcription factors(TFs)-key gene mRNA molecular regulatory networks;CMap database was used to screen the potential small molecule drugs for HCC treatment.Results:A total of 146 DEGs were screened,including 30 upregulated genes and 116 downregulated genes.The GO functional enrichment analysis and KEGG pathway enrichment analysis results showed that the DEGs were significantly enriched in biological processes(BP)such as steroid,alkene compound,and hormone metabolism,as well as signaling pathways such as retinol metabolism,drug metabolism-cytochrome P450(CYP450),complement and coagulation cascades.The PPI network analysis identified 14 key genes,among which formimidoyltransferase cyclodeaminase(FTCD),secreted phosphoprotein 2(SPP2),thrombin-antithrombin complex(TAT),complement C6(C6),and cytochrome CYP450 family member 2C9(CYP2C9)were significantly associated with the prognosis,clinical pathological stage,and histological grade of the HCC patients and also had high diagnostic efficacy for HCC and were closely related to immune cell infiltration in HCC.Hsa-mir-182-5p,CUT-like homeobox 1(CUX1),early growth response 1(EGR1),SMAD family member 4(SMAD4),and tumor protein P53(TP53)were identified as the important regulators targeting the above-mentioned prognosis-related key genes.DL-thiorphan,promethazine,and apigenin may have the therapeutic effects on HCC.Conclusion:FTCD,SPP2,TAT,C6,and CYP2C9 may be the potential targets for the diagnosis,prognosis,and treatment of HCC.Three predicted small molecule drugs,DL-thiorphan,promethazine,and apigenin,may provide the references for the development of therapeutic drugs for HCC.

Objective To investigate the serum levels of Sestrin2 and Survivin in patients with acute myo-cardial infarction(AMI)and their correlation with the degree of coronary artery stenosis.Methods A total of 120 AMI patients admitted to Hanzhong 3201 Hospital from October 2020 to December 2022 were selected as the observation subjects,and there were 67 cases of ST-segment elevation myocardial infarction(STEMI)and 53 cases of non-ST-segment elevation myocardial infarction(NSTEMI).According to the Gensini score,pa-tients were grouped into mild stenosis group and severe stenosis group,60 patients who underwent coronary angiography(stenosis degree＜50％)at the same time and did not meet the diagnosis standard of AMI were regarded as the control group.The levels of serum Sestrin2 and Survivin were detected by enzyme linked im-munosorbent assay,Spearman method was used for correlation analysis,and receiver operating characteristic curve was applied to analyze the diagnostic value of serum Sestrin2 and Survivin in severe stenotic AMI.Results There were statistically significant differences in brain natriuretic peptide,troponin,creatine kinase isoenzyme,left ventricular ejection fraction,fasting plasma glucose among the control group,NSTEMI group and STEMI group(P＜0.05).Compared with the control group,the levels of serum Sestrin2 and Survivin in NSTEMI group and STEMI group were obviously higher(P＜0.05).Serum Sestrin2 and Survivin levels in-creased with the increase of coronary artery lesion number and stenosis degree in AMI patients(P＜0.05).Serum Sestrin2 and Survivin levels were positively correlated with the number of coronary lesions,SYNTAX score and Gensini score in AMI patients(P＜0.05).The area under the curve(AUC)of serum Sestrin2 and Survivin in diagnosis of severe stenotic AMI alone and in combination were 0.840,0.823 and 0.920,respec-tively,and AUC of the combined detection was larger than those of singe detection(P＜0.05).Conclusion The serum levels of Sestrin2 and Survivin in patients with AMI are increased,they are related to the degree of coronary artery stenosis,and they may become marker to evaluate the degree of coronary artery disease.

In this study, 34 deep eutectic solvents (DESs) were successfully prepared for the extraction of proanthocyanidin from Rhodiolae Crenulatae Radix et Rhizomes. The extraction process was optimized using single factor exploration and Box-Behnken design-response surface analysis. The extraction rate was significantly improved when the molar ratio of choline chloride to 1,3-propanediol was 1:3.5 and the water content was 30% (V/V) in DESs. AB-8 macroporous resin and ethyl acetate were used for separation and refining, and the oligomer-rich proanthocyanidin components were eventually obtained. The ultraviolet (UV) and infrared (IR) spectra showed that the proanthocyanidins were mainly composed of catechin and epicatechin. To further clarify the chemical composition of proanthocyanidin, an ion scan list containing 156 proanthocyanidins precursors was obtained by constructing a proanthocyanidins structural library and mass defect filtering (MDF) algorithm, combined with the full mass spectrometry (MS)/dd-MS² scan mode that turns on the "if idle pick others" function. By using ultra-high performance liquid chromatography and high-resolution MS (UHPLC/HRMS), the analysis used both targeted and non-targeted methods to detect proanthocyanidins. Finally, 50 oligomeric proanthocyanidin (OPC) compounds were identified, including 7 monomers, 22 dimers, 20 trimers, and 1 tetramer, most of which were procyanidins of proanthocyanidins (84%), and a small amount of prodelphinidin (14%) and other types of proanthocyanidins (2%), which enabled the systematic characterization of proanthocyanidin components from Rhodiolae Crenulatae Radix et Rhizomes. Meanwhile, the comparison with the grape seeds OPCs standard (United States Pharmacopeia) revealed that the proanthocyanidins in Rhodiolae Crenulatae Radix et Rhizomes were more abundant, suggesting that the proanthocyanidins in Rhodiolae Crenulatae Radix et Rhizomes has promising applications.

Plant-derived nanovesicles have gained attention given their similarity to mammalian exosomes and advantages such as low cost, sustainability, and tissue targeting. Thus, they hold promise for disease treatment and drug delivery. In this study, we proposed a time-efficient method, PEG 8000 combined with sucrose density gradient centrifugation to prepare ginger-derived nanovesicles (GDNVs). Subsequently, curcumin (CUR) was loaded onto GDNV by ultrasonic incubation. The optimum conditions for ginger-derived nanovesicles loaded with curcumin (CG) were ultrasound time of 3 min, a carrier-to-drug ratio (GDNV:CUR) of 1:1. The study achieved a high loading capacity (94.027% ± 0.094%) and encapsulation efficiency (89.300% ± 0.344%). Finally, the drugs' in vivo distribution and anti-colitis activity were investigated in mice. CG was primarily distributed in the colon after oral administration. Compared to CUR and GDNV, CG was superior in improving disease activity, colon length, liver and spleen coefficients, myeloperoxidase activity, and biochemical factor levels in ulcerative colitis (UC) mice. In addition, CG plays a protective role against UC by modulating serum metabolite levels and gut flora. In summary, our study demonstrated that GDNV can be used for CUR delivery with enhanced therapeutic potential.
