Objective This study aimed to clarify the anti-influenza virus activity of Bingyanqing(BYQ),as well as to explore the mechanism of BYQ in treating influenza through network pharmacology and experimental verification.Methods The impact of BYQ on mortality,lung index,and viral load in an influenza mouse model was detected.We collected the ingredients and targets of BYQ formula by searching databases including TCMSP,Swiss Target Prediction and consulting the literature.The"ingredients-common target"network for anti-influenza effect of BYQ was constructed using Cytoscape software.The protein-protein interaction(PPI)network was constructed using the STRING database and Cytoscape software,and the core targets were screened.Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses were performed for common targets.The effect of BYQ on reducing influenza-induced oxidative damage,the expression of antioxidant and pro-oxidant enzyme,P65 phosphorylation and nuclear factor E2-related factor 2(Nrf2)nuclear translocation in vivo were investigated.Results BYQ significantly reduced mortality,lung index,pulmonary viral load and lung injury in a mouse model of influenza.We obtained one hundred and ninety-three of BYQ active compounds,which corresponded to three hundred and thirty-eight targets.There are 180 influenza-related targets among them.Nine targets,including IκBα kinase α(CHUK),IκBα kinase γ(IKBKG),NF-κB p65(RELA),tumor necrosis factor(TNF)and interleukin 6(IL6),were identified as potential core targets.GO analysis indicated that BYQ is involved in several biological functions,including antibacterial and antioxidant stress responses.KEGG analysis revealed the involvement of several viral and immune-related pathways for BYQ in treating influenza,including herpes simplex virus,influenza A virus,TNFα and toll-like receptor pathways.In vivo studies showed that high-dose BYQ significantly reduced pulmonary malondialdehyde(MDA)levels(P＜0.01)and increased total superoxide dismutase(SOD)activity(P＜0.001)in a mouse mode of influenza compared to oseltamivir phosphate.The treatment group with the combination of BYQ&oseltamivir phosphate had lower levels of NADPH oxidase 2(NOX2)and 4(NOX4)(P＜0.001),and higher levels of catalase(CAT)and glutathione peroxidase 4(GPX4)(P＜0.001)in the lungs than oseltamivir phosphate group.The combined treatment group showed more significant Nrf2 nuclear translocation(P＜0.05)than the oseltamivir phosphate group.However,there was no significant difference in P65 phosphorylation levels between the combination treatment group and the oseltamivir phosphate group(P＜0.05),but P65 phosphorylation levels in both groups were lower than in the model group(P＜0.05).Conclusion BYQ exhibits significant anti-influenza virus activity,manifests a dual effect by inhibiting the synthesis of pro-oxidant enzymes and promoting the antioxidant system,thereby alleviates the oxidative stress damage caused by influenza.

Objective To explore the changes of resting-state degree centrality(DC)in elderly patients with chronic insomnia disorder(CID).Methods Resting-state functional magnetic resonance imaging(rs-fMRI)data were collected from 26 untreated elderly patients with CID(CID group)and 45 healthy controls(HC)(HC group).Two-sample t-test was conducted to compare the intergroup differences in whole-brain DC values,and the correlation between DC values in different brain regions and clinical indicators were analyzed,and logistic regression analysis was performed to verify the diagnostic efficacy of changes in DC values for elderly CID.Results Compared with the HC group,the DC values of the right insula,left rolandic operculum,and opercular part of right inferior frontal gyrus in the elderly CID group decreased[P＜0.05,false discovery rate(FDR)corrected],while the DC values of the right middle frontal gyrus increased(P＜0.05,FDR corrected).And the DC values of the opercular part of right inferior frontal gyrus in the elderly CID group were positively correlated with sleep efficiency(r=0.504,P=0.009)and self-rating depression scale(SDS)(r=0.401,P=0.042),respectively.The sensitivity of DC value in the opercular part of right inferior frontal gyrus for diagnosing elderly CID was 0.822,the specificity was 0.615,and the accuracy was 0.701.Conclusion Elderly CID patients have abnormal DC values in the right insula,left rolandic operculum,opercular part of right inferior frontal gyrus and right middle frontal gyrus,which may provide imaging evidence for exploring the pathogenesis of CID and clinical diagnosis and treatment.

Objective:To explore the characteristics of gray matter volume (GMV) and structural covariant network (SCN) in patients with cerebral small vessel disease (CSVD) related cognitive impairment.Methods:This was a cross-sectional study. Ninety-eight patients with CSVD who attended Wuxi People′s Hospital of Nanjing Medical University between October 2021 and December 2022 were prospectively included. The patients were evaluated using the cognitive status assessment scale and were categorized into 57 cases in the CSVD with cognitive impairment group and 41 cases in the CSVD without cognitive impairment group according to the presence or absence of cognitive impairment. 3D-T 1WI structural image data were collected, and GMV differences between the two groups were compared by SPM 12 toolbox and CAT12 toolkit. At the same time, Pearson correlation analysis was also performed to analyze the GMV of differences between the 2 groups and cognitive status assessment scale scores. The BCT software package based on MATLAB platform was used to construct the GMV-related structural covariant network (SCN), and the graph theory method was utilized for SCN analysis to calculate the area under the curve (AUC) of the global and local parameters within the set sparsity range, and the permutation test was used to compare the differences in the AUC of the 2 groups. Results:In the CSVD with cognitive impairment group, GMV in bilateral hippocampus, parahippocampal gyrus, fusiform gyrus, and left amygdala was significantly lower than that in the CSVD without cognitive impairment group (family wise error corrected P<0.05), and the GMV in these regions had correlation with cognitive status assessment scale ( P<0.05). At the global network level of the SCN, the area under the curve (AUC) of the characteristic path length was significantly higher in the CSVD with cognitive impairment group than in the CSVD without cognitive impairment group ( P=0.023), while the AUC of global efficiency was significantly lower in CSVD with cognitive impairment group than in the CSVD without cognitive impairment group ( P=0.005). At the local level, the nodal degree and nodal efficiency of the left putamen were significantly decreased in the CSVD with cognitive impairment group compared to the CSVD without cognitive impairment group (false discovery rate corrected P<0.05). Conclusions:GMV reduce in patients of CSVD with cognitive impairment in the bilateral hippocampus, parahippocampal gyrus, fusiform gyrus, and left amygdala. In the structural covariance network, characteristic path length increase while global efficiency reduce, and node degree and nodal efficiency of the left putamen reduce.

Hepatocellular carcinoma (HCC) is characterized by high postoperative recurrence and mortality rates. In recent years, researchers have identified a significant correlation between microvascular invasion (MVI) and early postoperative recurrence and metastasis of HCC, making it a focal point of HCC research. Accurate preoperative prediction of MVI occurrence and the implementation of relevant interventions (such as expanded resection) could provide substantial benefits to patients. This study analyzes global research over the past decade on MVI predictive indicators based on tumor biological characteristics, genetic measurements, imaging examinations, and tumor markers. The aim is to use these predictive indicators to objectively forecast the occurrence of MVI, thereby aiding in preoperative individual assessments and enhancing treatment plans.

Since the first case of corona virus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) at the end of 2019, the virus has spread rapidly around the world and has become a global public health problem. In the process of this virus epidemic, compared with the general population, cancer patients are considered to be highly susceptible people, especially the lung cancer patients. Some studies have shown that angiotensin converting enzyme 2 (ACE2) may be the pathway for SARS-CoV-2 to infect the host. At the same time, ACE2 is often abnormally expressed in non-small cell lung cancer. Therefore, understanding the respective mechanisms of ACE2 in COVID-19 and non-small cell lung cancer has extremely important reference value for the study of vaccines and therapeutic drugs, and also provides meaningful guidance for the protection of patients with lung cancer during the epidemic. This article reviews the possible invasive mechanism of ACE2 in SARS-CoV-2 and its abnormal expression in non-small cell lung cancer.

Objective    To systematically evaluate the efficacy and safety of jejunostomy tube versus nasojejunal tube for enteral nutrition after radical resection of esophageal cancer. Methods    PubMed, EMbase, Web of Science, The Cochrane Library, CNKI, Wanfang, VIP and CBM databases were searched to collect the clinical effects of jejunostomy tube versus nasojejunal nutrition tube after radical resection of esophageal cancer from inception to October 2021. Meta-analysis was performed using RevMan 5.4 software. Results    Twenty-six articles were included, including 17 randomized controlled studies and 9 cohort studies, with a total of 35 808 patients. Meta-analysis results showed that: in the jejunostomy tube group, the postoperative exhaust time (MD=–4.27, 95%CI –5.87 to –2.66, P=0.001), the incidence of pulmonary infection (OR=1.39, 95%CI 1.06 to 1.82, P=0.02), incidence of tube removal (OR=0.11, 95%CI 0.04 to 0.30, P=0.001), incidence of tube blockage (OR=0.47, 95%CI 0.23 to 0.97, P=0.04), incidence of nasopharyngeal discomfort (OR=0.04, 95%CI 0.01 to 0.13, P=0.001), the incidence of nasopharyngeal mucosal damage (OR=0.13, 95%CI 0.04 to 0.42, P=0.008), the incidence of nausea and vomiting (OR=0.20, 95%CI 0.08 to 0.47, P=0.003) were significantly shorter or lower than those of the nasojejunal tube group. The postoperative serum albumin level (MD=5.75, 95%CI 5.34 to 6.16, P=0.001) was significantly better than that of the nasojejunal tube group. However, the intraoperative operation time of the jejunostomy tube group (MD=13.65, 95%CI 2.32 to 24.98, P=0.02) and the indent time of the postoperative nutrition tube (MD=17.81, 95%CI 12.71 to 22.91, P=0.001) were longer than those of the nasojejunal nutrition tube. At the same time, the incidence of postoperative intestinal obstruction (OR=6.08, 95%CI 2.55 to 14.50, P=0.001) was significantly higher than that of the nasojejunal tube group. There were no statistical differences in the length of postoperative hospital stay or the occurrence of anastomotic fistula between the two groups (P>0.05). Conclusion    In the process of enteral nutrition after radical resection of esophageal cancer, jejunostomy tube has better clinical treatment effect and is more comfortable during catheterization, but the incidence of intestinal obstruction is higher than that of traditional nasojejunal tube.

ObjectiveTo evaluate the Chinese guidelines and consensus of rehabilitation medicine published in the medical journals in 2022 using Scientific, Transparent and Applicable Rankings (STAR). MethodsGuidelines and consensus which were developed by Chinese institutions or led by Chinese scholars were retrieved in databases of CNKI, Wanfang Data, CBM, Chinese Medical Journal Network, PubMed and Web of Science, in 2022, followed by screening for rehabilitation medicine field. The literature were rated with STAR. ResultsSeven guidelines and eleven consensuses were included. The STAR scores ranged from 11.7 to 69.6, with a median score of 25.9 and mean score of 28.3. There was a significant difference in the total score between guidelines and consensus (U = 12.000, P = 0.014). The score ratio was high in the domains of recommendations (73.6%), evidence (39.5%) and others (33.3%), while it was low in the domains of protocol (1.4%), clinical questions (12.5%) and conflicts of interest (13.9%). The score ratio was high in the items of listing the institutional affiliations of all individuals involved in developing the guideline (94.4%), identifying the references for evidence supporting the main recommendations (94.4%), indicating the considerations (e.g., adverse effects) in clinical practice when implementing the recommendations (88.9%), and making the recommendations clearly identifiable, e.g., in a table, or using enlarged or bold fonts (75%); and it was low in the items of describing the role of funder(s) in the guideline development (0), indicating information about the evaluation and management of conflicts of interest (0), providing tailored editions of the guidelines for different groups of target users (0), presenting the guideline or recommendations visually, such as with figures or videos (0), providing details of the guideline protocol (2.8%), assessing the risk of bias or methodological quality of the included studies (2.8%), describing the responsibilities of all individuals or sub-groups involved in developing the guideline (5.6%), indicating how the clinical questions were selected and sorted (5.6%), formating clinical questions in PICO or other formats (5.6%), making the guideline accessible through multiple platforms (5.6%), and declaring that the funder(s) did not influence the guideline's recommendations (8.3%). ConclusionThe quality of current clinical practice guidelines and consensus of rehabilitation medicine is poor, which should be developed in accordance with the relevant standards.

Objective:To investigate the efficacy of acidified aliphatic ester in the treatment of atopic dermatitis (AD) in mouse models, and to preliminarily explore its mechanisms of action.Methods:Twenty female BALB/c mice aged 6 to 8 weeks were randomly divided into 2 groups: 5 mice in the blank control group were topically treated with absolute ethanol on both ears (14.3 μl per ear) every day, and 15 mice in the model group were topically treated with calcipotriol liniment (14.3 μl per ear) and 20 g/L ovalbumin (25 μl per ear) on both ears every day for 10 consecutive days to establish AD-like mouse models. From day 11, 15 mice in the model group were randomly divided into 3 groups (5 mice in each group), including AD model group, aliphatic ester group, and acidified aliphatic ester group; in the forenoon, all the 3 groups continued to be topically treated with calcipotriol liniment and ovalbumin to maintain AD-like models; in the afternoon, the aliphatic ester group and acidified aliphatic ester group were topically treated with aliphatic ester and acidified aliphatic ester respectively (10 μl per ear), and no treatment was given to the AD model group. Changes in body weight, ear thickness, ear skin lesion scores, and scratching frequency were observed. Ear skin swabs were obtained from the mice on days 10 and 14 for 16S rRNA gene - based microbial diversity tests. On day 14, mice were sacrificed after reflectance confocal microscopy examinations of the ear skin, ear tissues were resected for hematoxylin and eosin staining, mast cell staining, and real-time fluorescence-based quantitative PCR (RT-qPCR), and blood samples were collected for detection of serum IgE levels. One-way analysis of variance was used for analysis of data that met homogeneity of variance criteria, and least significant difference- t test for multiple comparisons. Results:On day 14, the severity of mouse ear lesions was the highest in the AD model group, followed in turn by the aliphatic ester group, acidified aliphatic ester group, and blank control group; compared with the AD model group, the acidified aliphatic ester group showed significantly decreased mouse ear thickness ( F = 897.50, P < 0.001), skin lesion scores ( F = 268.80, P < 0.001), scratching frequency ( F = 64.36, P < 0.001), and epidermal thickness ( F = 256.20, P < 0.001). In addition, RT-qPCR indicated that the expression of inflammatory factors such as interleukin (IL) -33, thymic stromal lymphopoietin, IL-4, and tumor necrosis factor-α in lesional areas, and the degree of mast-cell infiltration were all significantly lower in the acidified aliphatic ester group than in the AD model group ( F = 3.38, 8.70, 41.73, 44.30, 134.30, P = 0.049, = 0.001, < 0.001, < 0.001, <0.001, respectively). Microbial diversity tests showed that the acidified aliphatic ester treatment could inhibit the colonization of Staphylococcus spp. in the ears of AD-like mouse models, and the Shannon index and Simpson index significantly differed among the 4 groups ( F = 9.00, 7.92, P = 0.001, 0.002, respectively) . Conclusion:Acidified aliphatic ester could improve skin lesions of AD-like mouse models, possibly by regulating immunity, suppressing inflammation, and restoring skin microecological diversity.
