AIM:To investigate the impact of recombinant human CC16 protein(rhCC16)on cigarette smoke extract(CSE)-induced senescence-associated secretory phenotype(SASP)in human bronchial epithelial cells(HBECs)and in the lung tissues of chronic obstructive pulmonary disease(COPD)mice,and to explore the underlying mechanism.METHODS:HBECs were induced into cellular senescence using 5%CSE.The senescent HBECs were treated with 250 ng/mL rhCC16,and the levels of reactive oxygen species(ROS)were assessed using the 2',7'-dichlorodihydrofluorescein diacetate(DCFH-DA)method.The levels of trimethylated histone H3 at lysine 9(H3K9me3),a marker of senescence-associated heterochromatic foci(SAHF),were detected using a Western blot assay.RT-qPCR and ELISA were utilized to measure the mRNA expression and protein levels of SASP components including interleukin-1 beta(IL-1β),IL-6,IL-8,chemokine(C-X-C motif)ligand-1(CXCL-1),matrix metalloproteinase 1(MMP1)and MMP3.Passive smoking was con-ducted for six months to induce COPD in mice.RhCC16(2.5 μg/g body weight)or an equal volume of PBS(20 μL)was intranasally administered from the 16th week of smoking in the COPD+rhCC16 group or COPD+PBS group,respectively,with administration 2 hours before smoking.ROS levels in lung tissue cells were investigated using DCFH-DA staining.H3K9me3 levels in lung tissues were tested using Western blot assay.RT-qPCR and ELISA were performed to examine the mRNA expression and protein levels of IL-1β,IL-6,IL-8,CXCL-1,MMP1 and MMP3.RESULTS:DCFH-DA staining results showed that CSE stimulation increased ROS levels in HBECs,while rhCC16 treatment reduced them(P＜0.01).Western blot results indicated that CSE stimulation elevated H3K9me3 levels in HBECs,which were decreased with rhCC16 treatment(P＜0.01).RT-qPCR and ELISA assays demonstrated that CSE stimulation upregulated the mRNA and protein levels of IL-1β,IL-6,IL-8,CXCL-1,MMP1 and MMP3 in HBECs,which were reduced with rhCC16 admin-istration(P＜0.05).DCFH-DA staining results showed an increase in ROS levels in the lung tissues of COPD mice,which were decreased with rhCC16 administration(P＜0.01).Western blot data revealed an increase in H3K9me3 levels in the lung tissues of COPD mice,which were reduced with rhCC16 treatment(P＜0.01).RT-qPCR and ELISA assays demon-strated an upregulation of the mRNA and protein levels of IL-1β,IL-6,IL-8,CXCL-1,MMP1 and MMP3 in the lung tis-sues of COPD mice,which were reduced with rhCC16 treatment(P＜0.05).No statistically significant differences were ob-served in the above-mentioned indicators between the lung tissues of COPD and COPD+PBS mice(P＞0.05).CONCLU-SION:rhCC16 can effectively inhibit CSE-induced SASP in HBECs and in the lung tissues of COPD mice,with its under-lying mechanism potentially related to the inhibition of the ROS-H3K9me3 signaling pathway.

ObjectiveTo explore the potential mechanism of Dingchuan Granule （定喘颗粒， DG） in the treatment of respiratory syncytial virus （RSV） pneumonia. MethodsA total of 60 male Sprague Dawley （SD） rats were randomly divided into control group， model group， ribavirin group， DG low-dose group， DG middle-dose group， and DG high-dose group， with 10 rats in each group. Except for the control group， rats were administrated with RSV via intranasal drip. After model establishment， the DG low-， middle-， and high-dose groups were administrated via oral gavage with DG at 3.47， 6.93， and 13.86 g/（kg·d） respectively， while the ribavirin group was administrated via oral gavage with ribavirin at 15.75 mg/（kg·d）. The drug was given once daily for one week. The rats in the control group and the model group were not given any drug， only subjected to the grasping action. Twenty-four hours after the last administration， the pathological changes of lung tissues were observed and scored using HE staining. The levels of serum inflammatory factors， including tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， and interleukin-6 （IL-6）， were detected by colorimetry. The protein levels of nuclear factor （erythroid derived 2）-like 2 （Nrf2）， Kelch-like ECH-associated protein 1 （Keap1）， heme oxygenase 1 （HO-1）， and NAD（P）H quinone dehydrogenase 1 （NQO1） in lung tissues were measured by Western Blot. The RSV load as well as the gene expression levels of Nrf2， Keap1， HO-1， and NQO1 in lung tissues were determined by qRT-PCR. The level of reactive oxygen species （ROS） in rat lung tissues was detected using chemiluminescence. The levels of glutathione （GSH） and malondialdehyde （MDA） in rat lung tissues were measured by a microassay. ResultsCompared with the control group， other groups had significant increases in pathological score of lung tissue， RSV load， levels of ROS， MDA， serum TNF-α， IL-1β， and IL-6； decrease in GSH level， increases in expression level of Keap1 protein and its mRNA in lung tissue， and significant decrease in levels of Nrf2， HO-1， expression level of NQO1 protein and its mRNA （P＜0.05）. Compared with the model group， all the above-mentioned indicators in the DG low-， middle-， and high-dose groups and the ribavirin group were improved to varying degree （P＜0.05）. The levels of serum TNF-α， IL-1β， and IL-6 in rats of DG dose groups showed a dose-dependent pattern， the DG high-dose group exhibiting the best effect （P＜0.05）. The DG high-dose group was superior to the DG low- and middle-dose groups in reducing the levels of ROS and MDA， and increasing the level of GSH in lung tissues （P＜0.05）. The DG high-dose group and the ribavirin group had better effect than the DG middle-dose group in reducing the RSV load （P＜0.05）. The DG high-dose group was superior to the ribavirin group in improving the protein levels of Nrf2， Keap1， HO-1， and NQO1 （P＜0.05）. ConclusionDG could inhibit oxidative stress by regulating the Nrf2/Keap1/HO-1/NQO1 signaling pathway to improve pulmonary inflammation and treat RSV pneumonia， with the DG high-dose group showing the best effect.

Ketamine， a non-competitive N-methyl-D-aspartate （NMDA） receptor antagonist， has gained increasing attention for its rapid antidepressant effects in treatment-resistant depression （TRD） and suicidal ideation. Its mechanisms include NMDA receptor blockade， AMPA receptor activation， and upregulation of BDNF/mTOR signaling. Its enantiomers， esketamine and R-ketamine， as well as its metabolites， exhibit differences in efficacy and mechanisms. Intranasal esketamine has been approved in the Europe， United States， and China for TRD， demonstrating rapid efficacy in alleviating depressive symptoms and acute suicidal ideation. In contrast， R-ketamine demonstrates potential for longer-lasting effects and a improved safety profile. This review summarizes recent advances in the pharmacology， pharmacokinetics， and clinical applications of ketamine and its enantiomers in depressive disorders， bipolar disorder， substance use disorders， post-traumatic stress disorder and obsessive-compulsive disorder. Despite ketamine's multifaceted therapeutic potential， safety concerns such as dissociation， cognitive impairment， and abuse liability warrant continued attention.［Funded by Key Project of Natural Science Research for Universities of Anhui Provincial Education Department （number， 2023AH050647）； Anhui Provincial Department of Education Outstanding Young Talent Support Program Project 2022 （number， gxyqZD2022022）］

Objective:To explore the clinical effect of the whole-process management scheme of daytime minimally invasive liver resection surgery based on the enhanced recovery after surgery (ERAS) concept.Methods:This is a retrospective case series study. The data of 55 patients who underwent minimally invasive daytime liver resection surgery under the ERAS concept at the Department of General Surgery,Sir Run Run Shaw Hospital, Zhejiang University School of Medicine from January 2023 to August 2024. There were 22 males and 33 females;aged (48.2±15.1) years (range: 16 to 77 years). All patients were classified as Grade 2 according to the American Society of Anesthesiologists physical status classification. Among them, 7 cases were complicated with liver cirrhosis and 10 cases had fatty liver. A multidisciplinary team was formed, consisting of surgeons, anesthesiologists, rehabilitation physicians, psychologists, pharmacists, acute pain management team, operating room nurses, day surgery ward nurses, and ERAS specialized nurses. After strict evaluation by surgeons and anesthesiologists, patients suitable for daytime liver resection surgery were implemented with the ERAS whole-process management plan for liver resection on the basis of routine nursing care.Results:Among the 55 patients, 50 were discharged smoothly within 48 hours, while 5 were transferred to specialized departments for further treatment due to not meeting the discharge criteria, with a smooth daytime discharge rate of 90.9%. Among the 50 patients, 30 underwent laparoscopic surgery and 20 underwent robotic-assisted surgery. The surgery time was (91.6±28.2)minutes(range:45 to 165 minutes), with the intraoperative blood loss of only (30.5±25.5)ml(range:5 to 100 ml). Pathological examination results showed that among the 50 patients, 13 cases had hepatocellular carcinoma, 21 cases had hepatic hemangioma, 4 cases had hepatic cyst, 8 cases had focal nodular hyperplasia, 1 case had low-grade dysplastic nodule, 1 case had hepatolithiasis, 1 case had lymphoma, and 1 case had vascular, fibrous and lymphoid tissue proliferation. There were 44.0% patients who were able to get out of bed on the day of surgery. The hospital stay was (1.8±0.4)days(range:1 to 2 days), and the hospitalization cost was (34 499±20 330)yuan(range:11 724 to 73 488 yuan). No complications requiring special treatment outside the conventional pathway were observed during the hospital stay and follow-up period. At the 2-week outpatient follow-up, no significant abnormalities were found in all patients, and the wound healing was good.Conclusions:The daytime liver resection surgery based on the ERAS whole-process management plan has shown good feasibility in clinical practice. It helps to simplify medical process, shorten hospital stay, and reduce medical costs.

Glucosidases are an indispensable class of enzymes in the sugar metabolism of organisms. To investigate the biological functions and expression patterns of α-glucosidases (AGLUs) and β-glucosidases (BGLUs), we identified the two family members in the genome of melon (Cucumis melo). The number, location on chromosomes, gene structure, subcellular localization, conserved motifs, and phylogenetic relationship of the two family members were analyzed. Based on the cis-acting elements in the promoter region and protein interaction models, their functions were preliminarily predicted. Furthermore, the gene expression of the two family members was determined by qRT-PCR. The results showed that the melon genome contained five AGLU family members on five chromosomes, and all of the five members were located in the extracellular matrix, with the amino acid sequence lengths ranging from 899 aa to 1 060 aa. The melon genome carried 18 BGLU family members on 8 chromosomes, and all the members were located in the cell membrane or cytoplasm, with the amino acid lengths ranging from 151 aa to 576 aa. The qRT-PCR results showed that the expression of about 50% of the genes was down-regulated upon cold stress. CmAGLU5 and CmBGLU7 may be key members of the two families, respectively, in response to cold stress. The expression of all members of the two families was up-regulated under abscisic acid (ABA), high salt, and drought stress. In the AGLU family, CmAGLU3 was the key gene in response to ABA and high salt stress, while CmAGLU4 was the key gene in response to drought stress. In the BGLU family, CmBGLU18 was the key gene in response to ABA, while CmBGLU6 was the key gene in response to high salt and drought stress.
