With the continuous advancement of internet technology and the improvement of internet literacy among the general population, the concept of online-offline integration in internet hospitals has gradually gained acceptance and has been applied and developed both domestically and internationally. In thoracic surgery, the applicability of this model lies in enhancing efficiency and delivering comprehensive, diversified, and personalized medical services to address complex and severe conditions. However, challenges such as hardware limitations and diagnostic/treatment risks persist during the implementation of internet hospitals. Through future in-depth and localized research, the online-offline integration of internet hospitals is expected to undergo further development and refinement. This progress will facilitate its integration into clinical practice in thoracic surgery, ultimately providing patients with improved medical care services.

The mild-natured and bitter-flavored traditional Chinese medicines (MB-TCMs) are an important class of TCMs that have been widely used in clinical practice and recognized as safe long-term treatments for chronic diseases. However, as an important class of TCMs, the panorama of pharmacological effects and the mechanisms of MB-TCMs have not been systemically reviewed. Compelling studies have shown that gut microbiota can mediate the therapeutic activity of TCMs and help to elucidate the core principles of TCM medicinal theory. In this systematic review, we found that MB-TCMs commonly participated in the modulation of metabolic syndrome, intestinal inflammation, nervous system disease and cardiovascular system disease in association with promoting the growth of beneficial bacteria Bacteroides, Akkermansia, Lactobacillus, Bifidobacterium, Roseburia as well as inhibiting the proliferation of harmful bacteria Helicobacter, Enterococcus, Desulfovibrio and Escherichia-Shigella. These alterations, correspondingly, enhance the generation of protective metabolites, mainly including short-chain fatty acids (SCFAs), bile acid (BAs), 5-hydroxytryptamine (5-HT), indole and gamma-aminobutyric acid (GABA), and inhibit the generation of harmful metabolites, such as proinflammatory factors trimethylamine oxide (TAMO) and lipopolysaccharide (LPS), to further exert multiplicative effects for the maintenance of human health through several different signaling pathways. Altogether, this present review has attempted to comprehensively summarize the relationship between MB-TCMs and gut microbiota by establishing the TCMs-gut microbiota-metabolite-signaling pathway-diseases axis, which may provide new insight into the study of TCM medicinal theories and their clinical applications.

Objective To screen mitochondria-targeting differential genes in alveolar macrophages of silicosis pa-tients and explore the role of mitochondrial homeostasis in alveolar macrophages of silicosis patients.Methods High-throughput sequencing dataset GSE174725 was downloaded,and differentially expressed genes were screened with R software and P＜0.05,|LogFC|＞1,and then intermixed with mitochondrial gene bank MitoCarta3.0 to obtain mitochondria-targeted differentially expressed genes.Then enrichment analysis was carried out to obtain the biological processes and pathways involved in differential genes,and the protein-protein interaction network was constructed.In addition,alveolar macrophages from silicosis patients and healthy controls were collected,the ex-pression levels of differential genes were detected by RT-qPCR,and the expressions of mitochondria-related factors mitochondrial fusion protein 1(MFN1),optic atrophy 1(OPA1)and dynamin-related protein 1(DRP1)in alveolar macrophages of silicosis patients were investigated by Western blot.Results A total of 204 differentially expressed genes were screened in silicosis patients,among which 62 differentially expressed genes were up-regulated,142 dif-ferentially expressed genes were down-regulated,and 22 differentially expressed genes were mitochondria-targeted.The concentration analysis of differentially expressed genes targeted by mitochondria showed that the cell compo-nents mainly enriched included mitochondrial membrane,endoplasmic membrane side components,etc.The bio-logical processes mainly enriched included mitochondrial electron transfer from NADH to ubiquinone,inflammatory response,immune response,etc.The main molecular functions enriched included the rotation mechanism of proton transport ATP synthase activity,NADH dehydrogenase activity,chemokine activity,etc.KEGG enrichment analy-sis mainly focused on the involvement in chemical carcinogenesis-ROS,IL-17 signaling pathway,toll-like receptor signaling pathway,chemokine signaling pathway,TNF signaling pathway,etc.In addition,RT-qPCR results showed that the expressions of mitochondrial cytochrome coxidase 1,mitochondrial cytochrome coxidase 2,mito-chondrial cytochrome coxidase 3,mitochondrially encoded NADH dehydrogenase 1,mitochondrially encoded NADH dehydrogenase 3,mitochondrially encoded NADH dehydrogenase 5,superoxide dismutase and mitochondri-ally encoded ATP synthase 6 gene were down-regulated in silicosis patients(P＜0.05).Western blot and RT-qPCR results showed that,in silicosis patients,the expression of MFN1 and OPA1 decreased(P＜0.05),while the expression of DRP1 increased(P＜0.05).Conclusion Bioinformatics analysis and validation,eight mito-chondrial targeted differential genes(MT-CO1,MT-C02,MT-CO3,MT-ND1,MT-ND3,MT-ND5,SOD and MT-ATP6)were finally obtained,which were enriched in mitochondrial respiratory chain and oxidative stress pathways and might play an important role in the process of silicosis.

Aiming at the current situation of insufficient integration of medical humanities teaching and clinical practice,as well as the need for further research and improvement in the teaching system,guided by the concept of medicine and humanistic literacy integration advocated by the new medical science,this paper deeply discussed the construction of clinical medical humanities teaching system from four aspects,including the selection of clinical medical humanities teachers and team building;the teaching path that combines theoretical education,narrative medicine,and clinical skill training infused with medical humanities content;curriculum ideological and political construction with the goal of establishing the core concept and value orientation of"patient-centered";the teaching assessment and evaluation method characterized by formative evaluation.The clinical medical humanities teaching system emphasizes the practicality,experiential,and emotional aspects of medical humanities teaching,deeply integrating medical humanities with clinical practice teaching content throughout the clinical internship period of medical education,with a view to enhancing the humanistic practice ability and literacy of medical students.

Objective:To investigate the impact of a pain management model based on clinical pathway (CP) refinement on postoperative pain relief, recovery, and cognitive function in patients undergoing orthopedic joint surgery.Methods:A total of 150 orthopedic joint surgery patients admitted to Handan Central Hospital from February 2018 to January 2021 were selected. They were randomly divided into an observation group (treated with a pain management model based on CP refinement) and a control group (treated with conventional pain management) using a random number table method, with 75 patients in each group. We compared the differences in pain relief, recovery, cognitive function, and postoperative complication rates between two groups of patients.Results:The Visual Analogue Scale (VAS) scores of the observation group patients at 2, 6, 12, and 24 hours after surgery were lower than those of the control group, and the differences were statistically significant (all P<0.05). 24 hours after surgery, the Japanese Orthopaedic Association (JOA) scores of both groups of patients decreased compared to before treatment, and the angle of straight leg elevation test increased compared to before treatment (all P<0.05). In addition, the JOA scores of the observation group were lower than those of the control group, and the angle of straight leg elevation test was greater than that of the control group, with statistical significance (all P<0.05). 24 hours after surgery, the Mini-mental State Examination (MMSE) scores of both groups of patients increased (all P<0.05), and the MMSE scores of the observation group were higher than those of the control group, with statistical significance (all P<0.05). The incidence of postoperative nausea and vomiting in the observation group was significantly lower than that in the control group, and the difference was statistically significant (all P<0.05). Conclusions:The analgesic model based on CP refined management has improved the postoperative analgesic effect, recovery, and cognitive function of patients undergoing orthopedic joint surgery. It is recommended to promote it clinically.

Objective: To investigate the dietary lead exposure level among children aged 3 to 4 years in Jiading District, Shanghai Municipality, and assess the health risk caused by lead exposure, so as to provide the basis for the management of children's food safety. Methods: Based on the 2023 Dietary and Health Status Surveillance Project in Jiading District, children aged 3 to 4 years from 12 streets (townships) in Jiading District were selected as the subjects using a multi-stage stratified random sampling method. The consumption frequency and daily intake of seven subcategories of four major food groups (beans, tofu), cereals (wheat, rice), meat (animal viscera), and aquatic products (mantis shrimps, bivalves) consumed by children over the past three months were collected using a food frequency questionnaire. Food samples were collected according to the food safety risk monitoring plan in Jiading District, and the lead content was detected. The health risks of dietary lead exposure among 3-4-year-old children were quantitatively assessed using the single-factor pollution index method, the Nemerow comprehensive pollution index method, and the margin of safety (MOS) method. Results: A total of 143 3-4-year-old children were surveyed, including 69 boys (48.25%) and 74 girls (51.75%). A total of 317 food samples were tested, and lead was detected in all seven subcategories of food samples, with an overall detection rate of 77.29%. The detection rates of lead in bivalves and mantis shrimps of aquatic products were relatively high (98.75% and 100.00%, respectively). The mean lead content of various foods ranged from 0.003 4 to 0.090 7, with the highest level found in bivalves. The lead content of all food samples did not exceed the standard. The single-factor pollution index of seven subcategories ranged from 0.017 2 to 0.148 0, and the Nemerow comprehensive pollution index ranged from 0.116 5 to 0.424 4, both of which were less than 0.7. The MOS (mean) ranged from 0.000 3 to 0.003 9, with an overall MOS (mean) of 0.012 2. The MOS (P95) ranged from 0.005 7 to 0.055 9, with an overall MOS (P95) of 0.112 4, both of which were less than 1. Conclusions The lead pollution level in the diet among children aged 3 to 4 years in Jiading District is safe and clean, with an acceptable impact on food safety. However, the detection rate of lead is relatively high, and the main source of dietary lead exposure is aquatic products.

Epstein-Barr virus (EBV) associated post-transplant lymphoproliferative disorders (PTLD) are one of the most severe complications after hematopoietic stem cell transplantation (HSCT). This study includes 31 cases of aplastic anemia (AA) patients who developed PTLD after haploidentical transplantation, summarizing their clinical characteristics and categorizing them into either rituximab monotherapy group or combination therapy group based on whether their condition improved by 1 log after a single dose of rituximab. The incidence of PTLD after HSCT in children with AA was 10.16%, and the incidence of PTLD in patients with age >10 years was significantly increased ( χ2=11.336, P=0.010). Of the 31 patients, 27 were clinically diagnosed and 4 were pathologically confirmed. Finally, 15 patients were classified into the rituximab treatment group and 15 patients into the combination treatment groups. Finally three patients died, and the 2-year overall survival rate was (89.7±5.6) %. Standard pre-treatment protocols and EBV reactivation are risk factors affecting the prognosis of PTLD. There was no statistically significant difference in the impact of the two treatment schemes on prognosis.

Objective:To investigate the efficacy and safety of venetoclax combined with the decitabine, cytarabine, and homoharringtonine (HHT) regimen and donor lymphocyte infusion (DLI) for the preventive and salvage therapy of pediatric acute myeloid leukemia (AML) /myelodysplastic syndrome (MDS) after allogeneic hematopoietic stem cell transplantation (HSCT) .Methods:A total of 29 relapsed pediatric/minimal residual disease-positive AML after HSCT were recruited at the Peking University Institute of Hematology from January 1, 2021, to June 1, 2023. They were treated with the above combination regimen and administered with DLI after 24-48 hours at the end of chemotherapy, and the treatment response and adverse reactions were regularly assessed.Results:The overall response rate (ORR) was 75.8%, CR rate was 88.9% (8/9) in the hematologic relapse group, and MRD negativity rate was 61.1% (11/18) in the MRD-positive group. The incidence of agranulocytosis, anemia, and thrombocytopenia with a classification above grade 3 were 100%, 82.7%, and 100%, respectively. The median time of the granulocyte deficiency period was 15 days. Acute graft-versus-host diseases (aGVHD) with a classification of grades Ⅲ-Ⅳ occurred in 11.1% of the patients after DLI, while moderate or severe cGVHD occurred in 7.4% of the patients. The single risk factor for ORR was MNC counts of less than 10×10 8/kg, and the relapse occurred within 100 days. At a median follow-up of 406 days, the 1-year OS was 65%, and the 1-year OS was 57% in the group with no reaction ( P=0.164) compared with 71% in the group who had an overall reaction. Conclusion:The combined regimen based on the DAC, VEN, and modified HA regimen showed a high response rate in the salvage therapy for pediatric AML after the relapse of HSCT. However, bridging to transplantation should be performed immediately after remission to result in a long survival rate.

To explore the method of constructing the first-class undergraduate course of Treatise on Febrile Diseases. The undergraduates majoring in traditional Chinese medicine were selected as the teaching subjects. Three combinations (combination of theory and clinics, combination of science and education, and combination of ideological/political education and professional education) were adopted as the starting point. A variety of teaching methods were used. The combination of in-class and after-class and the combination of theory and clinics were implemented. Course construction was carried out from the aspects of course objectives, course resource construction, course content, organization and implementation, and course evaluation methods. Emphasis was placed on the process evaluation and formative evaluation. Questionnaire survey and final examination were used to evaluate the teaching effect. The results showed that a total of 10 first and second prizes were awarded in the provincial and municipal innovation competitions related to the theory of cold disease in the past three years. During the same time, more than 70 medical records were collected and collated, 82 research papers and 155 learning experiences were documented, five communities were visited along with the affiliated hospital and the school hospital for providing healthcare services in rural areas, and more than 20 traditional Chinese diagnosis and treatment activities were performed in these communities. The average score of students in overall course evaluation was 87. More than 94.00% (141/150) students highly evaluated the course construction. They believed that the course construction was very helpful to the theoretical study and clinical application of Treatise on Febrile Diseases, and improved their levels and abilities in classic reading, medical case evaluation and analysis, and syndrome differentiation and treatment. Students' recognition of this course has been improved and phased results have been achieved.
