[摘 要] 目的：探究纺锤体蛋白1（SPIN1）促进胃腺癌细胞迁移与侵袭的分子机制。方法: 通过TCGA数据库数据分析胃腺癌组织中SPIN1 mRNA表达与上皮间质转化（EMT）评分、血管生成评分间的相关性。收集2018年8月至2021年11月期间山东第一医科大学附属省立医院手术切除的52例胃腺癌患者的癌组织制成组织芯片，每例均包含胃腺癌组织、对应癌旁组织及淋巴结转移灶，通过免疫组织化学法检测胃腺癌组织中SPIN1与STAT3的蛋白表达水平及相关性。通过Transwell实验研究干扰SPIN1对胃腺癌细胞侵袭与迁移的影响。使用GEPIA2网站分析SPIN1基因与Janus-激酶/信号转导和转录激活因子（JAK/STAT）通路相关因子在胃腺癌中的表达相关性。通过qPCR法、WB法检测干扰SPIN1后JAK/STAT通路相关mRNA和蛋白的表达变化。结果: TCGA数据库数据分析结果显示，SPIN1表达与EMT评分和血管生成评分呈正相关（均P < 0.05）。SPIN1与STAT3在胃腺癌组织和淋巴结转移灶中表达升高（均P < 0.05），在癌旁胃黏膜组织中阴性表达。SPIN1与STAT3的表达显著正相关（P < 0.05）。干扰SPIN1后胃腺癌细胞的迁移、侵袭能力明显降低（P < 0.05或P < 0.01）。GEPIA2网站分析结果显示，SPIN1基因与JAK1、JAK2、STAT1、STAT2及STAT3表达均呈显著正相关（均P < 0.05）。干扰SPIN1后JAK2、STAT3的mRNA水平下降，而JAK1、STAT1、STAT2的mRNA水平变化不明显。WB法实验结果表明，干扰SPIN1后JAK2、STAT3、p-JAK2及p-STAT3的蛋白表达均显著降低（均P < 0.01），过表达SPIN1后JAK2、STAT3、p-JAK2及p-STAT3的蛋白表达均显著升高（均P < 0.01）。结论: SPIN1可通过参与JAK2/STAT3信号通路促进胃腺癌细胞迁移与侵袭。

Objective To explore a method to improve the accuracy and generalization ability of medical diagnostic neural network models under conditions of small data volumes,and to address the issue of poor neural network model performance in computer-aided diagnosis of nail diseases due to limited training data.Methods A dual-model strategy integrating instance segmentation with fine-grained feature classification was proposed.The neural network model based on dual-model strategy was trained using the dataset of Image-Based Intelligent Diagnosis of Nail Disease Model task of the first National Digital Health Innovation Application Competition & Health and Medical Big Data Theme Competition.This dataset covered 8 types of nail diseases,including nail matrix nevi,paronychia,nail psoriasis,onychomycosis,subungual hemorrhage,melanonychia,periungual warts,and nail melanoma,with class imbalance present.The diagnostic performance of the dual-model strategy was evaluated and compared with single-model strategies(image classification models[ResNet50 and Swin Transformer]and target detection model based on faster region-based convolutional neural network[Faster R-CNN])under the same hardware and software training conditions.Results The dataset included 1 048 samples,including 210 cases of nail matrix nevi,186 cases of paronychia,69 cases of nail psoriasis,203 cases of onychomycosis,149 cases of subungual hemorrhage,71 cases of melanonychia,93 cases of periungual warts,and 67 cases of nail melanoma,with 90％used for training various models and 10％for evaluation.The micro F1 score was 0.324 in the image classification model based on ResNet50,0.381 in the image classification model based on Swin Transformer,0.572 in the target detection model based on Faster R-CNN,and 0.714 in the dual-model strategy model Mask R-CNN+Swin Transformer.The accuracy rates for diagnosing different nail diseases in the dual-model strategy were:nail matrix nevi 80.95％(17/21),paronychia 89.47％(17/19),nail psoriasis 100.00％(7/7),onychomycosis 70.00％(14/20),subungual hemorrhage 73.33％(11/15),melanonychia 14.29％(1/7),periungual warts 55.56％(5/9),and nail melanoma 42.86％(3/7).The micro F1 score for evaluating the dual-model strategy on a test set of 1 000 cases was 0.844.Conclusion The dual-model strategy can effectively combine models with different functions to well accomplish the task of intelligent diagnosis of nail diseases under small data volume training conditions.

Clinical cure (herein referred to as functional cure) is currently recognized as the ideal therapeutic goal by the guidelines for the prevention and treatment of chronic hepatitis B (CHB) at home and abroad. China has achieved significant results in research and exploration based on pegylated interferon alpha therapeutic strategies to promote the effectiveness of CHB clinical cure rates in clinical practice. The summary and optimization of clinical cure strategies in different clinical type classifications, as well as the exploration of clinical cure continuity and long-term outcomes, are of great significance for solving the current bottleneck problem and our future efforts in the developmental directions of clinical cure in CHB populations.

Yigongsan is derived from Xiaoer Yaozheng Zhijue written by QIAN Yi in the Northern Song dynasty， which is the No. 3 formula in the Catalogue of Ancient Famous Classical Formulas（The Second Batch of Pediatrics） released by the National Administration of Traditional Chinese Medicine（TCM） in September 2022， and it can be developed as a class 3.1 new TCM drug. By referring to ancient medical books and modern literature， this study conducted herbal textual research on Yigongsan from five aspects， including historical evolution， origin and processing， dosage conversion， usage and preparation methods， and functional application， then formed the key information table of this formula， in order to provide reference for the development of reference samples and preparations of Yigongsan. Based on the results of the study， it is recommended that Panax ginseng should be removed the basal part of stem（rhizoma）， Poria cocos should be removed the peel， Citrus reticulata should be cut into shreds and Glycyrrhiza uralensis should be used. According to 4.13 g/Qian（钱）， 1 g/slice for ginger， 3 g for each jujube and 300 mL/Zhan（盏）， the doses of Ginseng Radix， Poria， Atractylodis Macrocephalae Rhizoma， Glycyrrhizae Radix et Rhizoma， Citri Reticulatae Pericarpium， Zingiberis Rhizoma Recens， Jujubae Fructus were 1.652， 1.652， 1.652， 1.652， 1.652， 5， 6 g， and the total amount was 19.26 g. The decocting method was to crush the medicinal materials into fine powder with 50-80 mesh， add 300 mL of water and decoct to 210 mL for each dose， then remove the dregs and take it warmly. This formula was recorded in ancient books as the main treatment for the cold-deficiency of spleen and stomach， and Qi stagnation in children with vomiting and diarrhea and lack of appetite. It has been flexibly applied by later generations of physicians， and is often used to treat anorexia， inflammation of the digestive tract， diarrhea and other diseases in children.

Objective:To evaluate and summarize the best evidence of exercise management of cancer-related fatigue in cancer patients.Methods:Evidence-based questions were identified using the PIPOST model to determine retrieval strategies and inclusion and exclusion criteria. According to the "6S" evidence model, the clinical decision-making, best clinical practice, guidelines, systematic review and expert consensus on the exercise management of cancer-related fatigue in cancer patients were searched in UpToDate, British Medical Journal Best Practice, Joanna Briggs Institute Evidence-based Health Care Center Database, Cochrane Library, National Institute for Health and Clinical Excellence, National Comprehensive Cancer Network, Guidelines International Network, Canadian Medical Association: Clinical Practice Guidelines, PubMed, Web of Science, Embase, CINAHL, China National Knowledge Infrastructure, WanFang Data, VIP, China Biology Medicine disc and professional association platform. The retrieval time limit was from the establishment of the database to January 31, 2022. Three researchers evaluated the quality of the literature and collated, evaluated and integrated the evidence.Results:A total of 20 articles were included, including 1 clinical decision-making, 4 guidelines, 2 evidence summaries, 10 systematic reviews, and 3 expert consensus. A total of 25 best evidences were summarized from 8 aspects, namely, safety and effectiveness of exercise, exercise timing, exercise evaluation, exercise principle, exercise mode, exercise intensity and duration, exercise compliance and exercise risk management.Conclusions:The best evidence on the exercise management of cancer-related fatigue in cancer patients provides evidence-based evidence support and reference opinions for clinical standardized exercise. It is suggested that medical and nursing staff should select the best evidence according to the specific clinical situation and individual differences of patients in the process of evidence transformation, and formulate a personalized exercise management plan to alleviate the cancer-related fatigue of patients.

The most common subtype of lung cancer is non-small cell lung cancer (NSCLC), which has a poor prognosis and seriously threatens the health of human beings. The multidisciplinary comprehensive treatment model has gradually become the mainstream of NSCLC treatment. Traditional Chinese medicine (TCM) can be used effectively either as an adjunctive therapy or alone throughout the NSCLC therapy, which has a significant impact on survival, quality of life, and reduction of toxicity. Therefore, this paper reviewed the theoretical basis, the latest clinical application, and combined treatment mechanisms in order to explore the advantage stage of TCM treatment and the synergistic therapeutic mechanisms.
