Aim To screen and study the effects of Tao Hong Si Wu decoction(THSWD)-mediated treat-ment on circular RNA(circRNA)expression profiles in rats with middle cerebral artery occlusion(MCAO),and investigate the possible roles and molecular mecha-nisms of THSWD.Methods Next-generation RNA sequencing was conducted to identify circRNA expres-sion profiles in MCAO rats after treatment with THSWD and compared with the MCAO model group and control group.Bioinformatics analysis was performed to predict the potential target microRNAs and mRNAs.Gene On-tology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analyses for the potential target mRNAs were applied to explore the potential roles of differentially expressed circRNAs.RT-qPCR was performed to verify circRNAs with significant differences in expression.Results We identified 87 significantly differentially expressed circRNAs between the MCAO group versus the control group,and 86 sig-nificantly differentially expressed circRNAs between the MCAO group versus the THSWD group.respective-ly.Among them,17 circRNAs induced by the MCAO model were reversed via treatment with THSWD.To demonstrate the roles of mRNAs targeted by DECs,the GO and KEGG databases were used.Further analysis revealed that five circRNAs may play important roles in the development of MCAO.Conclusions The com-prehensive expression profile of circRNAs in rats with middle cerebral artery occlusion after THSWD treat-ment is determined for the first time,suggesting that the therapeutic effect of THSWD on MCAO may be a-chieved by regulating the expression of circRNAs.

Aim The present study was conducted to investigate the expression of organic anion transporter 1(OAT1)in synovial tissue of collagen-induced arthritis(CIA)rats and the effect of paeoniflorin-6'-O-benzene sulfonate(CP-25),and meanwhile reveal its potential regulatory mechanism.Methods The rat CIA model was established and treated with CP-25(50 mg·kg-1·d-1),paroxetine(15 mg·kg-1·d-),prosta-glandin E receptor 4(EP4)antagonist(3 mg·kg-1·d-1),or a combination of CP-25(50 mg·kg-1·d-1)plus EP4 antagonist(3 mg·kg-1·d-1),while methotrexate(0.5 mg·kg-1·3d-1)was used as the positive control drug.Clinical manifestation of CIA rats,including arthritis index,numbers of swollen joints,paw volume of non-injected hind and clinical scores was measured.Moreover,X-ray imaging of paw,pathological examination of the ankle joint and quantitative assessment were conducted.The concen-tration of serum prostaglandin E2(PGE2)was quanti-fied using the ELISA.Western blot analysis was em-ployed to assess the levels of phospho-G protein-cou-pled receptor kinase 2(p-GRK2),protein kinase A(PKA),EP4 and OAT1 membrane proteins of rat syn-ovial tissues following CP-25 treatment.Results The administration of CP-25 resulted in a reduction in foot swelling,global score,arthritis index,paw volume of non-injected,and numbers of swollen joints in CIA rats.Pathological examination and X-ray analysis re-vealed that CP-25 significantly ameliorated the patho-logical changes and bone erosion degree of CIA rats.CP-25 significantly lowered PGE2 concentration in the serum of CIA rats.In the CIA model group,membrane expression of OAT1 and EP4 in synovial tissues of rats was significantly downregulated.Treatment with CP-25 or paroxetine resulted in a significant upregulation of OAT1 and EP4 expression and the effect of CP-25 on OAT1 was blocked when EP4 antagonist was used to-gether.Furthermore,the expression of p-GRK2 in syn-ovial tissue from CIA rats was significantly upregulat-ed,and however,CP-25 or paroxetine interventions led to a significant reduction in p-GRK2 expression.The expression trend of PKA was similar to that of OAT1.Conclusion OAT1 membrane expression is reduced in the synovial tissue of CIA rats,and CP-25 treatment increases OAT1 membrane expression.The PGE2-EP4-PKA pathway may be involved in the regu-lation of OAT1 by CP-25.

Objective To evaluate the effect of manual massage on complications after endoscopic foam sclerotherapy injection for the treatment of internal hemorrhoids.Methods Consecutive 113 patients with grade Ⅰinternal hemorrhoids were prospectively enrolled and completed endoscopic foam sclerotherapy.The patients were randomly divided into a massage group(n=65)and a control group(n=68).Massage group performed manual perianal massage,Visual analogue scale(VAS)was used to evaluate perianal pain.The postoperative bleeding,short-term and long-term efficacy were also compared.Results The median VAS of 24 h postoperation was 1.0(0.0,3.0)in massage group,which was significantly lower than 2.0(1.0,4.0)in control group,the difference was statistically significant(P=0.014).The no bleeding rate of one week postoperation was 84.6％in massage group,which was significantly higher than 64.7％in control group,the difference was statistically significant(P=0.009).After 12 weeks,6 months and 12 months of follow-up,there were no significant differences in cure rate and remission rate between the two groups(P＞0.05).Conclusion Manual massage after endoscopic sclerosing agent injection is beneficial to relieve postoperative pain of grade Ⅰ internal hemorrhoids and reduce bleeding.

MicroRNAs(miRNAs)are small non-coding RNAs that are closely associated with the occur-rence and progression of tumors and other diseases.However,miRNAs require high-sensitivity and high-specificity detection due to their low abundance,high sequence homology,and rapid degradation.The RNA-cleaving deoxyribozyme(RCD)is a functional single-stranded DNA molecule that enables specific cleavage of substrates to release miRNAs that can be recycled with the assistance of metal ions,prompting cyclic signal amplification.Recently,developing new methods based on RCD catalytic amplification for miRNA high-sensitivity detection has become the focus of researchers.Based on combing with the various new technologies and materials in miRNA biosensors,this study classifies and reviews the new methods for detecting miRNAs based on deoxyribozyme catalytic amplification developed in recent years.We sepa-rate these miRNA detection strategies into three categories:RCDs combined with DNA self-assembly,i-sothermal amplification,and nanomaterials.We explore the basic principles of each approach,the latest research advancements,and application scenarios in biomedical sensors and medical detection.This re-view provides a foundation and reference for further research of highly sensitive and accurate miRNA de-tection strategies.

Objective:To explore the independent risk factors of acute respiratory distress syndrome (ARDS) in patients with sepsis, establish an early warning model, and verify the predictive value of the model based on synthetic minority oversampling technique (SMOTE) algorithm.Methods:A retrospective case-control study was conducted. 566 patients with sepsis who were admitted to Jinan People's Hospital from October 2016 to October 2022 were enrolled. General information, underlying diseases, infection sites, initial cause, severity scores, blood and arterial blood gas analysis indicators at admission, treatment measures, complications, and prognosis indicators of patients were collected. The patients were grouped according to whether ARDS occurred during hospitalization, and the clinical data between the two groups were observed and compared. Univariate and binary multivariate Logistic regression analysis were used to select the independent risk factors of ARDS during hospitalization in septic patients, and regression equation was established to construct the early warning model. Simultaneously, the dataset was improved using the SMOTE algorithm to build an enhanced warning model. Receiver operator characteristic curve (ROC curve) was drawn to validate the prediction efficiency of the model.Results:566 patients with sepsis were included in the final analysis, of which 163 developed ARDS during hospitalization and 403 did not. Univariate analysis showed that there were statistically significant differences in age, body mass index (BMI), malignant tumor, blood transfusion history, pancreas and peripancreatic infection, gastrointestinal tract infection, pulmonary infection as the initial etiology, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score, sequential organ failure assessment (SOFA) score, albumin (Alb), blood urea nitrogen (BUN), mechanical ventilation therapy, septic shock and length of intensive care unit (ICU) stay between the two groups. Binary multivariate Logistic regression analysis showed that age [odds ratio ( OR) = 3.449, 95% confidence interval (95% CI) was 2.197-5.414, P = 0.000], pulmonary infection as the initial etiology ( OR = 2.309, 95% CI was 1.427-3.737, P = 0.001), pancreas and peripancreatic infection ( OR = 1.937, 95% CI was 1.236-3.035, P = 0.004), septic shock ( OR = 3.381, 95% CI was 1.890-6.047, P = 0.000), SOFA score ( OR = 9.311, 95% CI was 5.831-14.867, P = 0.000) were independent influencing factors of ARDS during hospitalization in septic patients. An early warning model was established based on the above risk factors: P1 = -4.558+1.238×age+0.837×pulmonary infection as the initial etiology+0.661×pancreas and peripancreatic infection+1.218×septic shock+2.231×SOFA score. ROC curve analysis showed that the area under the ROC curve (AUC) of the model for ARDS during hospitalization in septic patients was 0.882 (95% CI was 0.851-0.914) with sensitivity of 79.8% and specificity of 83.4%. The dataset was improved based on the SMOTE algorithm, and the early warning model was rebuilt: P2 = -3.279+1.288×age+0.763×pulmonary infection as the initial etiology+0.635×pancreas and peripancreatic infection+1.068×septic shock+2.201×SOFA score. ROC curve analysis showed that the AUC of the model for ARDS during hospitalization in septic patients was 0.890 (95% CI was 0.867-0.913) with sensitivity of 85.3% and specificity of 79.1%. This result further confirmed that the early warning model constructed by the independent risk factors mentioned above had high predictive performance. Conclusions:Risk factors for the occurrence of ARDS during hospitalization in patients with sepsis include age, pulmonary infection as the initial etiology, pancreatic and peripancreatic infection, septic shock, and SOFA score. Clinically, the probability of ARDS in patients with sepsis can be assessed based on the warning model established using these risk factors, allowing for early intervention and improvement of prognosis.

Objective To propose a method for classifying small bowel capsule endoscopy images by combining the Swin Transformer network with an improved Adapt-RandAugment data augmentation approach,aiming to enhance the accuracy and efficiency of small bowel lesion classification and recognition.Methods An Adapt-RandAugment data augmentation approach was formulated based on the RandAugment data enhancement sub-strategy and the principles of no feature loss and no distortion when enhancing small bowel capsule endoscopy images.In the publicly available Kvasir-Capsule dataset of small bowel capsule endoscopic images,the Adapt-RandAugment data augmentation approach was trained based on the Swin Transformer network,and the convolutional neural networks ResNet152 and DenseNet161 were used as the benchmarks to validate the combined Swin Transformer network and Adapt-RandAugment data augmentation approach for small bowel capsule endoscopy image classification.Results The proposed algorithm gained advantages over ResNet152 and DenseNet161 networks in the indicators,which had the macro average precision(MAC-PRE),macro average recall(MAC-REC),macro average F1 score(MAC-Fi-S)being 0.383 2,0.314 8 and 0.290 5 respectively,the micro average precision(MIC-PRE),micro average recall(MIC-REC)and micro average F1 score(MIC-Fi-S)all being 0.755 3,and the Matthews correlation coe-fficient(MCC)being 0.452 3.Conclusion The proposed small bowel capsule endoscopy image classification method based on Swin Transformer network and Adapt-RandAugment data augmentation approach behaves well in classified recognition efficiency and accuracy.[Chinese Medical Equipment Journal,2024,45(6):9-16]

The gut microbiota plays a pivotal role in the immunomodulatory and protumorigenic microenviron-ment of colorectal cancer(CRC).However,the effect of ginsenoside Rk3(Rk3)on CRC and gut microbiota remains unclear.Therefore,the purpose of this study is to explore the potential effect of Rk3 on CRC from the perspective of gut microbiota and immune regulation.Our results reveal that treatment with Rk3 significantly suppresses the formation of colon tumors,repairs intestinal barrier damage,and regulates the gut microbiota imbalance caused by CRC,including enrichment of probiotics such as Akkermansia muciniphila and Barnesiella intestinihominis,and clearance of pathogenic Desulfovibrio.Subsequent metabolomics data demonstrate that Rk3 can modulate the metabolism of amino acids and bile acids,particularly by upregulating glutamine,which has the potential to regulate the immune response.Furthermore,we elucidate the regulatory effects of Rk3 on chemokines and inflammatory factors associated with group 3 innate lymphoid cells(ILC3s)and T helper 17(Th17)signaling pathways,which inhibits the hyperactivation of the Janus kinase-signal transducer and activator of transcription 3(JAK-STAT3)signaling pathway.These results indicate that Rk3 modulates gut microbiota,regulates ILC3s immune response,and inhibits the JAK-STAT3 signaling pathway to suppress the development of colon tumors.More importantly,the results of fecal microbiota transplantation suggest that the inhibitory effect of Rk3 on colon tumors and its regulation of ILC3 immune responses are mediated by the gut microbiota.In summary,these findings emphasize that Rk3 can be utilized as a regulator of the gut microbiota for the prevention and treatment of CRC.

Aim To screen and study the expression of long non-coding RNA (IncRNA) in rats with middle cerebral artery occlusion (MCAO) with MCAO treated with Tao Hong Si Wu decoction (THSWD) and determine the possible molecular mechanism of THSWD in treating MCAO rats. Methods Three cerebral hemisphere tissue were obtained from the control group, MCAO group and MCAO + THSWD group. RNA sequencing technology was used to identify IncRNA gene expression in the three groups. THSWD-regulated IncRNA genes were identified, and then a THSWD-regu-lated IncRNA-mRNA network was constructed. MCODE plug-in units were used to identify the modules of IncRNA-mRNA networks. Gene ontology (GO) and kyoto encyclopedia of genes and genomes (KEGG) were used to analyze the enriched biological functions and signaling pathways. Cis- and trans-regulatory genes for THSWD-regulated IncRNAs were identified. Reverse transcription real-time quantitative pol-ymerase chain reaction (RT-qPCR) was used to verify IncRNAs. Molecular docking was used to identify IncRNA-mRNA network targets and pathway-associated proteins. Results In MCAO rats, THSWD regulated a total of 302 IncRNAs. Bioinformatics analysis suggested that some core IncRNAs might play an important role in the treatment of MCAO rats with THSWD, and we further found that THSWD might also treat MCAO rats through multiple pathways such as IncRNA-mRNA network and network-enriched complement and coagulation cascades. The results of molecular docking showed that the active compounds gallic acid and a-mygdalin of THSWD had a certain binding ability to protein targets. Conclusions THSWD can protect the brain injury of MCAO rats through IncRNA, which may provide new insights for the treatment of ischemic stroke with THSWD.
