Objective To explore the medicinal mechanism of Actinidia Chinensis Planch Radix(ACPR)in the treatment of colorectal cancer(CRC)by network pharmacology and molecular docking technology.Methods The genes involved in the effects of the main chemical components and disease genes of ACPR were screened from the TCM database and disease database.The main genes were analyzed through protein interaction network analysis,and molecular docking was performed on the main chemical components and key targets.The effects of the drug on tumor cells were measured,and the levels of key proteins in the signaling pathway were detected.Results The primary components of ACPR for treating CRC include quercetin,β-sitosterol,aloe baicalin,and catechin.It targets 144 protein interaction sites and were involved in the protein interaction network,with key genes including AKT1,TP53,MAPK1,JUN,and TNF.The recognition network includes five modules that were involved in various biological processes and signaling pathways.The main components exhibited excellent or good activity when interacting with these targets.At a certain concentration,the drug could inhibit the proliferation,invasion,and migration of colorectal cancer cells and affect the PI3K/AKT signaling pathway.Conclusion ACPR has been used to treat colorectal cancer through multiple pathways and multiple targets,among which the PI3K/AKT signaling pathway may be the mechanism.

Objective:To explore the association between oral health status, the lower respiratory tract microbiome, and the frequent acute exacerbation phenotype in chronic obstructive pulmonary disease (COPD).Methods:This cross-sectional study enrolled 39 patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) hospitalized in the Department of Respiratory Medicine, Henan Provincial People′s Hospital between March 2021 and December 2022. Based on the number of hospitalization episodes for acute exacerbation in the past year, patients were divided into a frequent exacerbator group (≥2 times, n=28) and a non-frequent exacerbator group (<2 times, n=11). Bronchoalveolar lavage fluid (BALF) samples were collected from all subjects for metagenomic next-generation sequencing (mNGS). Oral health indicators and clinical data were also collected. Statistical analyses were performed using Spearman correlation analysis and multivariable Firth logistic regression analysis. Results:The frequent exacerbation group showed a significantly higher percentage of individuals with≥8 tooth loss compared to the non-frequent exacerbation group (96.4% vs 18.2%, P<0.001), a significantly younger age at first tooth loss in adulthood (53.96±7.30 years vs 62.10±5.80 years, P=0.003), and a significantly higher proportion of individuals who hardly brushed their teeth (50.00% vs 9.09%, P=0.038). The alpha-diversity indices of the lower respiratory tract microbiota were significantly lower in the frequent exacerbation group than in the non-frequent exacerbation group (all P<0.01). The relative abundances of Bacillota, Bacteroidota, Fusobacteriota, Streptococcus, Prevotella, Veillonella, Neisseria, Rothia, Prevotellamelaninogenica, Prevotellajejuni, Rothia mucilaginosa, Veillonella parvula, and Neisseria subflava were lower in the frequent exacerbation group (all P<0.05). In patients with AECOPD, the exacerbation frequency and the presence of ≥8 tooth loss were both negatively correlated with the Shannon index ( r=-0.854, P<0.001; r=-0.642, P<0.001, respectively). Further analysis revealed that Bacillota ( r=-0.862, P<0.001) and Streptococcus ( r=-0.814, P<0.001) were significantly negatively correlated with exacerbation frequency, while Pseudomonas was positively correlated with exacerbation frequency (all P<0.05). Bacillota ( r=0.369, P=0.021), Fusobacteriota ( r=0.368, P=0.021), and Veillonella ( r=0.379, P=0.017) were positively correlated with FEV 1% predicted. Multivariable Firth logistic regression analysis revealed that the first principal component of the microbial community ( OR=2.29, 95% CI: 1.20-11.07) and the loss of≥8 teeth ( OR=14.37, 95% CI: 1.42-482.51) were independent factors associated with frequent acute exacerbations. Conclusion:Frequent acute exacerbations of COPD are significant association with deteriorated oral health and dysbiosis of the lower respiratory tract microbiome, characterized by reduced alpha-diversity and depletion of commensal bacteria.

Objective:To explore the feasibility and safety of laparoscopic combined with colonoscopic transanal total mesorectal resection (laparoscopic combined with colonoscopic taTME) in the treatment of rectal cancer.Methods:The descriptive case series analysis method was adopted. From October 2023 to February 2024, the Department of Colorectal Surgery of Li Huili Hospital, Ningbo Medical Center, performed laparoscopic combined with colonoscopic taTME on 8 patients with rectal cancer. Among the 8 patients, there were 5 males and 3 females, aged from 56 to 74 years old, with a body mass index (BMI) of 20.3-26.7 kg/m2. All patients were pathologically diagnosed with rectal adenocarcinoma. The long diameter of the tumors was 2.0-6.5 cm, the lower edge of the tumors was 3-5 cm away from the anal verge. In terms of tumor TNM staging, there were 2 cases in stage I, 3 cases in stage II, and 3 cases in stage III. The surgical conditions, postoperative curative effects, and the occurrence of complications were observed.Results:All 8 patients successfully completed laparoscopic combined with colonscopic taTME, and there was no conversion to laparotomy. The operative time was 260 to 335 minutes, the intraoperative blood loss was 50 to 100 milliliters, and the distance from the tumor to the anal margin was 0.8 to 2.0 centimeters. All patients in the group underwent protective end ileostomy, and none of them underwent permanent enterostomy. Specimens were removed from the right lower abdomen in 7 cases and through the anus in 1 case. There was no residual cancer cells at the pathological resection margins postoperatively. All patients ambulated on the first day after the operation, and began to eat on the 2nd to 3rd day after the operation. Anastomotic leakage occurred in 1 patient after the operation, and the condition improved after conservative treatment. The length of hospital stay was 21 days. The other 7 patients were discharged from the hospital 8 to 12 days after the operation. Two patients completed the ileostomy closure surgery 3 months after the operation and recovered well. The patients were followed up until April 2024, during which there were no cases of tumor recurrence or death.Conclusion:For appropriate cases, laparoscopic combined with colonoscopic taTME is safe and feasible.

Objective To investigate alteration in brain gray matter volume in kidney transplant recipients(KTRs)and its correlation with post-traumatic stress symptoms(PTSS)in KTRs so as to provide neuro-imaging evidence for early detection and intervention of PTSS in KTRs.Methods Forty-six KTRs and 46 age-,sex-,and education-matched heath control(HCs)underwent brain MRI scanning with 3D T1-weighted structural images.Voxel-based morphometry(VBM)was applied to compare the gray matter volume between the two groups.For regions with significant differences in gray matter volume between KTRs and HCs,we analyzed the correlations with the Impact of Event Scale-Revised(IES-R)scores,which assess the severity of PTSS.Results Compared to HCs,KTRs showed significant reductions in gray matter volume in the bilateral precentral gyrus,middle frontal gyrus,supplementary motor area,medial paracingulate gyrus,and bilateral middle temporal gyrus(all P＜0.05,TFCE-FWE correction).The gray matter volume of the left middle frontal gyrus in KTRs was negatively correlated with their IES-R scores(r=-0.235,P=0.022).Conclusion KTRs exhibit abnormal gray matter volume,and the gray matter volume of the left middle frontal gyrus is correlated with the severity of PTSS.
