Background/Aims: Endoscopic radiofrequency ablation (ERFA) is a treatment option for superficial esophageal squamous cell neoplasia (ESCN), with a relatively low risk of stenosis; however, the long-term outcomes remain unclear. We aimed to compare the long-term outcomes of patients with widespread superficial ESCN who underwent endoscopic submucosal dissection (ESD) or ERFA. Methods: We retrospectively analyzed the clinical data of patients with superficial ESCN who underwent ESD or ERFA between January 2015 and December 2021. The primary outcome measure was recurrence-free survival. Results: Ninety-two and 33 patients with superficial ESCN underwent ESD and ERFA, respectively. The en bloc, R0, and curative resection rates for ESD were 100.0%, 90.2%, and 76.1%, respectively. At 12 months, the complete response rate was comparable between the two groups (94.6% vs 90.9%, p=0.748). During a median follow-up of 66 months, recurrence-free survival was significantly longer in the ESD group than in the ERFA group (p=0.004), while no significant differences in overall survival (p=0.845) and disease-specific survival (p=0.494) were observed.Preoperative diagnosis of intramucosal cancer (adjusted hazard ratio, 5.55; vs high-grade intraepithelial neoplasia) was an independent predictor of recurrence. Significantly fewer patients in the ERFA group experienced stenosis compare to ESD group (15.2% vs 38.0%, p=0.016). Conclusions The risk of recurrence was higher for ERFA than ESD for ESCN but overall survival was not affected. The risk of esophageal stenosis was significantly lower for patients who underwent ERFA.

Coronavirus disease 2019 (COVID-19) is an acute infectious respiratory disease that has been prevalent since December 2019. Chinese medicine (CM) has demonstrated its unique advantages in the fight against COVID-19 in the areas of disease prevention, improvement of clinical symptoms, and control of disease progression. This review summarized the relevant material components of CM in the treatment of COVID-19 by searching the relevant literature and reports on CM in the treatment of COVID-19 and combining with the physiological and pathological characteristics of the novel coronavirus. On the basis of sorting out experimental methods in vivo and in vitro, the mechanism of herb action was further clarified in terms of inhibiting virus invasion and replication and improving related complications. The aim of the article is to explore the strengths and characteristics of CM in the treatment of COVID-19, and to provide a basis for the research and scientific, standardized treatment of COVID-19 with CM.

Objective To explore the clinical efficacy of dual plasma molecular adsorption(DPMAS)sequential plasma exchange(PE)artificial liver mode in the treatment of liver failure(LF).Methods Eighty-five patients with LF receiving the artificial liver treatment in the Affiliated Hospital of Zunyi Medical Univer-sity from January 2020 to December 2023 were selected as the study subjects and divided into the study group(n=52)and the control group(n=33)according to the different treatment modes.The study group conduc-ted DPMAS sequential PE treatment and the control group underwent the PE treatment.The liver function[total bilirubin(TBIL),alanine aminotransferase(ALT),aspartate aminotransferase(AST),serum albumin(ALB),globulin(GLO),prealbumin(PAB)],Hb,coagulation function[platelet(PLT),plasminogen activity(PTA),international normalized ratio(INR),fibrinogen(FIB)]before treatment and at 24 h after treatment were compared between the two groups.Results Compared with before treatment,the levels of TBIL,ALT,AST,GLO and Hb after the first and second treatment in the two groups were decreased,ALB level in the control group and PAB level after the second time treatment was increased(P＜0.05).Compared with after the first treatment,the levels of TBIL,ALT and GLO after the second treatment in the two groups and the levels of AST and Hb in the study group were decreased,ALB level in the study group and PAB level in the two groups were increased(P＜0.05).Compared with before treatment,the levels of PLT and FIB after the first treatment in the two groups and INR level in the control group were decreased,PTA level in the control group was increased(P＜0.05).Compared with before treatment,the levels of PLT,INR and FIB after the second treatment in the two groups were decreased,PTA level was increased(P＜0.05).Compared with be-fore treatment,the levels of PLT,INR and FIB after the second treatment in the two groups were decreased,and PTA level was increased(P＜0.05).Compared with after the first treatment,PTA level after the second treatment in the study group was increased and INR level was decreased.Conclusion PE and DPMAS sequen-tial PE all could improve the liver function in the patients with LF,moreover the two times treatment has more significant effect.

Objective To explore the construction and visualization for knowledge graph of Ling Shu(Spiritual Pivot),with a view to providing ideas for the structured storage and display of the theoretical knowledge of the ancient Chinese medical books.Methods Using the professional idea of constructing knowledge graphs for reference,text mining technology was applied to construct the thesaurus,and then word division,entity recognition,and relationship extraction for the original text of Ling Shu were performed to get the elements of knowledge graph construction.The graph database Neo4j was used for the storage and query of the knowledge graph,and then the visual display of the knowledge graph was achieved.Results The 1 216 high-quality words consisting of the thesaurus of Ling Shu were obtained,and the construction of the knowledge graph of the theory of Ling Shu was realized.The constructed knowledge graph basically displayed the traditional Chinese medicine theories such as the correlation of visceral manifestations with essence qi,and the relationship between emotions and the five-zang organs described in Ling Shu,which made the retrieval and utilization of the related entities and relationships possible,and provided ideas for the structured storage and display of the theoretical knowledge of the ancient books of Chinese medicine.Conclusion The knowledge graph construction technology can be used to obtain the Chinese medicine theoretical knowledge graph of Ling Shu,and to display the knowledge connections of yin-yang and the five elements,and the internal organs and meridians expressed in the Ling Shu.The construction of the knowledge graph and its storage in the graph database enable the knowledge graph involved in the text of Ling Shu to be displayed in the form of visualized semantic network graph,and also make the embedding of other search systems such as the semantic search and semantic wiki possible,which will be helpful for the development of Chinese medicine intelligent medical services.

Airway mucus hypersecretion is one of the important pathophysiological and clinical manifestations of chronic obstructive pulmonary disease.It has been reported in the literature that COPD patients with chronic airway mucus hyperse-cretion have more frequent acute exacerbations,more severe lung function decline,and higher hos-pitalizations and mortality.Therefore,it is particu-larly critical to understand the pathogenesis of hy-persecretion of mucus in chronic obstructive pul-monary disease and find out effective treatment.This article focuses on the structure,significance of airway mucus and the mechanism of hypersecre-tion of mucus in chronic obstructive pulmonary dis-ease(COPD).In addition,we also summarized drug and non-drug therapy for chronic airway mucus hy-persecretion in this article.Drug therapy includes traditional drug therapy,some new targeted drug therapy for pathogenesis and traditional Chinese medicine therapy,and non-drug therapy includes smoking cessation,physical therapy and bronchos-copy therapy.We hope that it will provide new ideas and directions for the treatment of mucus hy-persecretion in COPD patients.
