With the continuous deepening of the concept of precision diagnosis and treatment for lung cancer, how to achieve higher efficiency and accuracy in the screening, diagnosis, and treatment pathways in clinical practice has become an important issue that urgently needs to be overcome. The current clinical difficulty lies in the fact that despite continuous advancements in imaging and molecular diagnostic technologies, there are still limitations in manual efficiency and subjective experience when it comes to massive data analysis and multi-scale feature extraction. Artificial intelligence (AI), especially algorithm systems based on deep learning, is an innovative technology capable of deeply empowering medical big data. This method utilizes algorithms such as convolutional neural networks, combined with radiomics, pathomics, and multi-modal data fusion analysis, demonstrating immense potential in early precise detection and benign-malignant differentiation of pulmonary nodules, digital pathological subtype recognition and non-invasive prediction of driver genes, precise 3D surgical planning and automatic delineation of radiotherapy target volumes, as well as dynamic risk warning during follow-up. This innovative technology provides a brand-new solution for realizing intelligent and individualized lung cancer diagnosis and treatment models. This consensus, based on the latest evidence from evidence-based medicine and combined with the development trends in the AI field and real-world clinical needs, was ultimately formed by gathering the consensus opinions of multidisciplinary experts in radiology, pathology, thoracic surgery, and other fields. The main content covers the application specifications of AI in the three core scenarios of lung cancer screening, diagnosis, and treatment, the technical standards for data collection and algorithm validation, as well as the ethical and regulatory challenges faced at the current stage. It aims to clarify the applicable boundaries of AI as a clinical auxiliary decision support tool, providing scientific guidance and standardized exploration directions for peers currently engaged in or planning to carry out AI-assisted clinical diagnosis, treatment, and translation of lung cancer.

Objective:To investigate the effect of early enteral nutrition on intestinal function in patients with complicated intra-abdominal infection.Methods:In this study,a prospective single-center randomized controlled trial was used to select 88 patients with severe abdominal infections in the surgical intensive care ward from January 2021 to December 2023.Among them,65 patients were eligible and were randomly divided into 33cases in the intervention group(who received early enteral nutrition),and 32cases in the control group(who did not receive early enteral nutrition).The clinical baseline characteristics of the two groups,conditions such as abdominal distension and diarrhea during enteral nutrition,intra-abdominal pressure,the time to reach the standard of complete enteral nutrition,and the indexes of pre-albumin,CRP,and leukocyte count on the third and the seventh day postoperative day were observed.The t-test was used to compare between groups for normally distributed measures.The Mann-Whitney U test was used to compare between groups for skewed measures.The χ2 test or continuity-corrected χ2 test was used to compare the count data between groups.Repeated measures data were analyzed by repeated measures ANOVA.Results:The clinical baseline characteristics of the two groups were completely matched;There were significant differences in the changes of intra-abdominal pressure over time between the two groups(Fgroup=9.665,P=0.004),There were significant differences in the changes of intra-abdominal pressure over time between the two intervention group(Ftime=64.124,P<0.001)and the control group.and the trend of intra-abdominal pressure reduction in the intervention group was more significant than that in the control group(Finteractive=3.938,P=0.023);The time required for the recovery of bowel sounds was significantly shorter in the experimental group than in the control group[(19.5±3.5)h vs(35.3±4.5)h,P<0.001,t=15.829];there was no significant difference in the frequency of abdominal distention,vomiting and aspiration between the two groups(P>0.05),and the difference in the frequency of diarrhea was statistically significant(P=0.003);The time to reach the standard of enteral nutrition in the intervention group was shorter than that in the control group[(6.3±1.2)d vs(7.4±1.5)d,P=0.002];The total hospital stay of the intervention group was significantly shorter than that of the control group[(11±3.2)d vs(14±4.1)d,P=0.007].The prealbumin(0.21±0.2,0.28±0.2)g/L,CRP(175.5±23.6,45.4±14.5)mg/L,and white blood cell count(11.7±2.9,9.1±3.5)109/L of the intervention group on the 3rd and 7th days after surgery were significantly improved compared with those of the control group(P<0.05).Conclusion:Early enteral nutrition can effectively promote the recovery of intestinal function in patients with complicated intra-abdominal infection.

Objective To investigate the feasibility and safety of transoral transgastric natural orifice transluminal endoscopic surgery(TG-NOTES)cholecystectomy in miniature pigs.Methods A total of 11 miniature pigs were selected as the experimental subjects and underwent TG-NOTES cholecystectomy.These pigs were divided into the Group A and Group B according to the surgical procedures.Among them,7 miniature pigs in the Group A underwent endoscopic cholecystectomy without dissecting the gallbladder triangle,while 4 miniature pigs in the Group B underwent endoscopic cholecystectomy after dissecting the gallbladder triangle.The success rate of surgery,the time of each stage of surgery,the incidence of complications,the success rate of cholecystectomy and the survival rate of miniature pigs in the two groups were counted.One miniature pig in the Group A and 4 miniature pigs in the Group B were selected for survival experiments.After surviving for 1 week,they were killed and dissected to observe the healing of incision and incidence of complications.Results The surgical survival rate of experimental animals was 100%,and the success rate of cholecystectomy was 100%.There was no significant difference in the surgical time,time of cut the stomach into the abdomen,time of gallbladder exploration or time of gallbladder removal of miniature pigs between the two groups(P>0.05).The time of ligating gallbladder artery of miniature pigs in the Group B was longer than that in the Group A,and the time of isdating gallbladder was shorter than that in the Group A,with statistically significant differences(P<0.05).There was no significant difference in the average number of complications of miniature pigs between the two groups(P>0.05).The dissection of animals after survival experiments revealed that the incisions healed well without serious complications.Conclusion This study successfully establishes the surgical model of TG-NOTES cholecystectomy,and confirms the safety and feasibility of TG-NOTES cholecystectomy.

Objective To evaluate the value of miniprobe endoscopic ultrasound(EUS)in guiding endoscopic treatment of small-diameter(maximum diameter less than 1 cm)and low-grade(G1 grade)rectum neuroendocrine neoplasm(R-NEN),and to provide evidence and clues for its clinical application and further research.Methods The clinical data of 85 cases of low-grade(G1 grade)R-NEN with a maximum diameter of less than 1 cm who underwent endoscopic treatment in our center from January 2014 to December 2020 were retrospectively analyzed.The patients were divided into the EUS group(37 cases)and control group(48 cases)according to whether EUS was performed before endoscopic treatment.The positive rate of incision margin,the incidence of complications,the recurrence rate,the hospital stay,the cost of hospitalization and endoscopic therapy were compared between the two groups.Results The positive rate of incision margin in the EUS group was significantly lower than that in control group(P<0.05).There was no significant difference in the incidence of complications,tumor recurrence rate,hospital stay or hospital costs between the two groups(P>0.05).There was statistically significant difference in the endoscopic therapy between the two groups(P<0.05).Conclusion Evaluating the lesion depth of small-diameter and low-grade(G1 grade)R-NEN before surgery by miniprobe EUS and selecting endoscopic surgery according to its results of can significantly reduce the residual risk of resection margin tumors.

Lyme disease is a natural zoonotic infectious disease transmitted by ticks infected by different genotypes of Borre-lia burgdorferi sensu lato,which was discovered in the 1970s.This pathogen is prevalent primarily in temperate and subtropi-cal areas.Dogs,cats,horses,cattle,deer,and other animals are susceptible,and humans are also susceptible hosts.The main symptoms of Lyme disease in humans are erythema migrans,arthritis,and other neurological symptoms,and the common symptoms in infected animals include joint diseases,coat shedding,fever,laminitis,and lameness.Lyme disease is wide-spread,but diagnosis is difficult,and this disease is easily misdiagnosed and missed.Awareness of Lyme disease must be in-creased to avoid its toll on livestock and the pet industry.Therefore,this article reviews research progress in diagnosis and con-trol technology for animal Lyme disease and Borrelia burgdorferi,to provide a reference for accurate,rapid diagnosis and con-trol of Lyme disease.

OBJECTIVE: To explore the value of multiple detection methods based on histopathology and supplemented by bone marrow or peripheral blood sample detections in the comprehensive diagnosis of mantle cell lymphoma (MCL). METHODS: The clinical, immunophenotypic, pathologic, cytogenetic and molecular features of 153 newly diagnosed MCL patients admitted to the hematology department of our hospital from May 2009 to September 2022 were analyzed. RESULTS: 144 (96.6%) of the 149 MCL patients who underwent marrow or peripheral blood IGH/CCND1 FISH detection at initial diagnosis were positive, of which 36 cases (24.2%) had a low proportion positive. The immunophenotypes in 115 patients were analyzed by flow cytometry (FCM), 89 cases (77.4%) conformed to MCL while 23 cases (20.0%) were initially diagnosed as B-cell lymphoproliferative disorders (B-LPD). Of the 75 cases who performed bone marrow biopsy, 50 cases (66.7%) had morphological and immunophenotypic characteristics consistent with MCL, 15 cases (20.0%) were classified as B-LPD, and 10 cases with no obvious abnormality. 77 patients underwent histopathology examination, of which 73 cases (94.8%) had typical clinicopathological features of MCL, including 2 CCND1 negative MCL, 2 pleomorphic variants, 5 pleomorphic variants and 4 cases diagnosed as other leukemia or lymphoma. Among 153 cases of MCL, 128 cases were classic MCL(cMCL), and another 25 cases (16.3%) were diagnosed as leukemic non-lymph node MCL (lnnMCL). The incidence of IGHV mutation, TP53 mutation and CD23 expression positive were significantly different between cMCL and lnnMCL. CONCLUSION Histopathology is still the main standard for the diagnosis of cMCL, and detection based on bone marrow or peripheral blood samples is an important means for the diagnosis of lnnMCL. Single marker or examination can cause a certain proportion of misdiagnosis. The accurate diagnosis of MCL depends on a combination of multiple detection methods.

The improvement of the harvest period standards is critical in the quality control of Chinese medicinal materials. The present study statistically analyzed the harvest period standards of plant medicinal materials in the 2020 edition of Chinese Pharmacopoeia(Vol.Ⅰ) and put forward the existing problems and suggestions based on herbal records and modern research to provide references for the improvement of the standards. According to the statistical analysis, in 499 types of plant medicinal materials, harvest period standards are recorded under 486 types, accounting for 97.4%, and are lacking in the remaining. Only one medicinal material(Stellariae Radix) is recorded with the standard of the harvest year. The standards of the harvest season and phenological period are recorded under 233 types, accounting for 46.7%. For 237 types, only harvest season is specified, accounting for 47.5%, and for 15 types, only harvest phenological period is specified, accounting for 3.0%. Among 222 types mainly derived from cultivation and 51 types from wild resources and cultivation, only 11 types are recorded with harvest period of cultivated products. Only Stellariae Radix is recorded with the harvest period standards for the wild and cultivated products separately. The harvest period standards of plant medicinal materials with different medicinal parts have certain rules to follow. The main problems about the harvest period standards are discovered. Specifically, no harvest period standards are recorded under 13 types of plant medicinal materials. Almost all perennial cultivated medicinal materials are not recorded with harvest year standard. No phenological period standard is found under 250 types of plant medicinal materials. There is no clear distinction between the harvest period standards of cultivated and wild products. The evidence for harvest period standards of 26 types of plant medicinal materials that can be harvested all year round is insufficient. As a result, it is proposed to strengthen basic research in response to the above-mentioned problems and improve the harvest period standards as soon as possible to ensure the quality of Chinese medicinal materials.
