目的 评估使用炎症、免疫及营养指标对于胃癌根治术后发生腹膜转移的预测作用，并建立适用于术前风险评估的预测模型。方法 回顾性收集2022—2024年苏州市立医院85例晚期胃癌患者的临床资料，按术后是否发生腹膜转移分为转移组44例与非转移组41例。通过分析比较两组间的营养参数［血清白蛋白、纤维蛋白原及预后营养指数（PNI）］、炎症指标［中性粒细胞计数、C反应蛋白、中性粒细胞与淋巴细胞比值（NLR）及全身免疫炎症指数（SII）］、肿瘤标志物以及免疫功能指标（淋巴细胞计数、IL-2、IL-6、TNF-α和IFN-γ）等。使用单因素及多因素Logistic回归分析确定独立预测因子，并构建预测模型，采用Bootstrap法内部验证，计算校正后的曲线下面积及收缩因子，以优化模型性能。结果 多因素分析结果显示，IL-6（OR=1.116，95%CI：1.020~1.224）与CA125（OR=1.016，95%CI：1.006~1.026）为术后腹膜转移的独立预测因素，构建的预测模型区分能力良好，初始AUC为0.801（95%CI：0.702~0.900），经Bootstrap校正后AUC为0.797，模型校准度理想，具有良好的临床稳健性。结论 基于术前IL-6和CA125水平的预测模型，可用于评估胃癌患者根治术后发生腹膜转移的风险。该模型可在术前阶段有效识别高风险病例，为临床制定个体化辅助治疗方案及随访策略提供关键参考，并具有改善患者预后的潜在价值。

       Objective To evaluate the predictive value of inflammatory，immune，and nutritional indicators for peritoneal metastasis after radical gastrectomy in gastric cancer and to establish a predictive model applicable for preoperative risk assessment．Methods Clinical data from 85 patients with advanced gastric cancer treated at Suzhou Municipal Hospital between 2022 and 2024 were retrospectively collected．Patients were divided into two groups based on postoperative peritoneal metastasis occurrence：a metastasis group（n=44）and a non-metastasis group（n=41）．Indicators analyzed and compared between groups included nutritional parameters（serum albumin，fibrinogen，PNI），inflammatory markers（neutrophil count，CRP，NLR，SII），tumor markers and immune indicators（lymphocyte count，IL-2，IL-6，TNF-α，IFN-γ）．Univariate and multivariate logistic regression analyses identified independent predictors for constructing the prediction model．Internal validation was performed using 1 000 bootstrap resamples to calculate the adjusted area under the curve（AUC）and shrinkage factor for model optimization．Results Multivariate analysis identified IL-6（OR=1.116，95%CI：1.020-1.224）and CA125（OR=1.016，95%CI：1.006-1.026） as independent predictors of postoperative peritoneal metastasis．The constructed predictive model demonstrated good discriminatory ability，with an initial AUC of 0.801（95%CI：0.702–0.900）and a bootstrap-corrected AUC of 0.797．The model exhibited ideal calibration and good clinical robustness．Conclusions This study established a predictive model based on preoperative IL-6 and CA125 levels to assess the risk of peritoneal metastasis after radical surgery in gastric cancer patients．The model effectively identifies high-risk cases preoperatively，providing critical guidance for developing individualized adjuvant treatment and follow-up strategies，with potential to improve patient prognosis．

       目的 探究单髁膝关节置换（UKA）联合注射布比卡因脂质体治疗老年孤立性内侧间室骨关节炎（OA）的效果，并分析其对患者术后长效镇痛的作用。方法 前瞻性选取2023年11月—2025年11月期间收治的80例老年孤立性内侧间室OA患者，分为对照组与研究组，各40例。两组患者均接受UKA手术治疗，研究组在术中于相同部位注射布比卡因脂质体，对照组于术中关节周围注射等体积的生理盐水混合物。比较两组术后疼痛强度，镇痛药物消耗与需求，早期膝关节功能恢复情况、早期膝关节功能，以及两组不良反应发生率。结果 研究组术后6 h、12 h、24 h及48 h VAS评分均低于对照组，术后48 h内，研究组中重度疼痛发生率较对照组低（P＜0.05）；研究组术后首次请求镇痛的时间晚于对照组，48 h内曲马多总消耗量及补救镇痛需求率均较对照组低（P＜0.05）；研究组在术后24 h、48 h、72 h的膝关节主动活动度较对照组大，研究组首次直腿抬高时间、术后下地行走时间及住院时间均较对照组短（P＜0.05）；术前两组膝关节协会评分（KSS）和牛津膝关节评分（OKS）评分无差异（P＞0.05）。术后1周，两组评分均改善，且研究组优于对照组（P＜0.05）；两组不良反应发生率无差异（P＞0.05）。结论 UKA术中联合应用布比卡因脂质体，能安全、有效地为老年孤立性内侧间室OA患者提供长效术后镇痛。且该方案不仅能显著减轻患者早期疼痛、减少阿片类药物依赖，更能有效促进膝关节早期功能恢复、缩短住院时间，并为患者获得更优的早膝关节功能奠定基础。

    Objective To investigate the efficacy of unicompartmental knee arthroplasty（UKA） combined with injection of bupivacaine liposomes in the treatment of elderly isolated medial compartment osteoarthritis（OA），and analyze its long-term analgesic effect on patients after surgery．Methods A prospective study was conducted on 80 elderly patients with isolated medial compartment OA admitted between November 2023 and November 2025．They were divided into a control group and a study group，with 40 patients in each group．Both groups of patients received UKA treatment．The study group received injection of bupivacaine liposomes at the same site during surgery，while the control group received injection of an equal volume of physiological saline mixture around the joints during surgery．Postoperative pain intensity，analgesic drug consumption and demand，early knee joint function recovery，early knee joint function were compared between two groups，and the incidence of adverse reactions was compared between the two groups．Results The study group had lower VAS scores at 6 h，12 h，24 h，and 48 h postoperatively compared to the control group．Within 48 hours after surgery，the incidence of moderate to severe pain in the study group was lower than that in the control group（P＜0.05）．The time to first postoperative analgesic request in the study group was later than that in the control group，and the total tramadol consumption and the need for analgesia within 48 hours were lower（P＜0.05）．The active range of motion of the knee at 24 h，48 h，and 72 h postoperatively was greater in the study group compared to the control group．Additionally，the time to first straight leg raise，time to ambulation，and length of hospital stay were all shorter in the study group（P＜0.05）．Preoperatively，there were no differences between the two groups in the Knee Society Score（KSS） and the Oxford Knee Score（OKS）（P＞0.05）．One week postoperatively，both groups showed improved scores，with the study group showing greater improvement than the control group（P＜0.05）．There was no significant difference in the incidence of adverse reactions between the two groups（P＞0.05）．Conclusions The combined use of bupivacaine liposomes during UKA can provide safe and effective long-term postoperative analgesia for elderly patients with isolated medial compartment OA．And this plan not only reduces early pain and opioid dependence in patients，but also effectively promotes early knee joint function recovery，shortens hospitalization time，and lays a solid foundation for patients to achieve better early knee joint function．

       乳腺癌（BC）发病率持续上升，已成为严重威胁公共健康的重大挑战，转移仍是导致患者死亡的主要原因。目前，切除肿瘤并辅以放化疗后仍有较大几率发生转移。此外，早期转移隐匿性强，干预措施不完善及耐药发生迅速均是预后不良的重要因素。细胞外囊泡（EVs）是由细胞释放的、具有膜结构的纳米级颗粒，是细胞间通讯的重要介质。EVs通过转运膜性组分、胞质蛋白及核酸等，调控乳腺癌的发生、进展及转移定植，其来源异质性决定了其在乳腺癌转移中发挥独特作用。本文重点总结了不同来源EVs作为液体活检标志物在转移预警中的价值，以及靶向EVs分泌或阻断其通讯网络在克服免疫治疗耐药中的潜在临床应用，以期为临床医生提供有价值的诊疗参考。

     The incidence of breast cancer（BC） continues to rise and has become a major public health challenge．Metastasis remains the principal cause of BC-related mortality．Currently，there remains a high probability of metastasis even after surgical tumor resection followed by radiotherapy and chemotherapy．The insidious nature of early metastasis，inadequate intervention strategies，and rapid development of drug resistance are all critical factors contributing to poor prognosis．Extracellular vesicles（EVs） are membrane-enclosed，nanoscale particles released by cells．As mediators of intercellular communication，EVs transfer membrane components，cytosolic proteins，and nucleic acids to recipient cells，thereby modulating BC initiation，progression，and metastatic dissemination．The heterogeneity of EV origins determines their distinct roles in breast cancer metastasis．This review focuses on summarizing the value of EVs from different sources as liquid biopsy biomarkers for metastasis warning，as well as their potential clinical applications in targeting EV secretion or blocking their communication networks to overcome immunotherapy resistance，aiming to provide valuable diagnostic and therapeutic references for clinicians．

      Objective To explore the effect of different duration of prone position ventilation（PPV）on enteral nutritional tolerance in patients with severe pneumonia combined with gastrointestinal dysfunction．Methods A total of 80 patients with severe pneumonia complicated by gastrointestinal dysfunction were treated in the Medical Intensive Care Unit（MICU）of a hospital from July 2020 to July 2023, and were selected as the research subjects．They were divided into the long-duration group（≥12 hours, n=40）and the short-duration group（<12 hours, n=40）according to the daily duration of PPV．The general data, oxygenation index, gastrointestinal function indicators（intra-abdominal pressure, serum gastrin[GAS] and vasoactive intestinal peptide[VIP]）, enteral nutrition achievement rate, and gastrointestinal complications of the two groups were compared．Results The oxygenation index of the short-duration group at 1 d, 3 d,a nd 5 d after treatment（[189.93±33.72], [247.53±63.01], and[325.03±58.11] mmHg, respectively）was significantly higher than that of the long-duration group（[161.63±36.88], [191.83±57.65], and[267.95±46.25] mmHg,respectively, all P<0.05）．The gastric residual volume of the short-duration group（[29.00±7.92], [19.75±4.45], and[11.00±1.87] mL, respectively）was significantly lower than that of the long-duration group（[75.03±23.29], [53.13±11.99], and[21.70±5.52] mL, respectively, all P<0.05）．The intra-abdominal pressure（[8.53±2.05] vs [9.75±2.05] mmHg）and VIP level（[61.14±7.63] vs [67.49±4.43] pg/mL）of the short-duration group after treatment were significantly lower than those of the long-duration group, while the GAS level（[65.02±8.84] vs [54.22±9.21] pg/mL）was significantly higher（all P<0.05）．The total incidence of gastrointestinal complications in the short-duration group（7.50%）was significantly lower than that in the long-duration group（25.00%, P=0.034）．Conclusions For patients with severe pneumonia complicated by gastrointestinal dysfunction, a daily duration of PPV within 12 hours can improve oxygenation and reduce the risk of gastrointestinal complications, which may be related to the reduction of intra-abdominal pressure, regulation of gastrointestinal hormone secretion, and improvement of enteral nutrition tolerance． 

       铁死亡是一种以铁依赖性脂质过氧化为特征的程序性细胞死亡形式。近年来研究表明，铁死亡与缺氧应答的关键调控因子——缺氧诱导因子（HIF）存在密切关联。HIF（包括HIF-1α、HIF-2α、HIF-3α三种亚型）调控的铁死亡在结直肠癌、胃癌、溃疡性结肠炎及其他胃肠黏膜损伤性疾病中发挥作用，影响疾病的发生发展。但目前关于HIF-铁死亡通路在不同胃肠道疾病中的差异化作用及调控机制尚未完全阐明。因此，本文对HIF各亚型调控铁死亡的分子机制及其在胃肠道疾病中的作用进行综述，以期为靶向HIF-铁死亡通路治疗相关疾病提供新的思路。

       目的   了解育龄期乳腺癌患者对子代健康和遗传风险担忧现状及其对癌症诊断前后生育意愿改变的影响。方法   于2019年11月—2020年9月，采用中文版癌症后生育忧虑量表（RCAC）-子女健康亚量表对广州市某三甲医院的230例育龄期乳腺癌患者进行调查，应用SPSS 26.0及PSM插件对结果进行统计分析。在进行子女健康亚量表得分低分组和中高分组患者的生育意愿改变率的比较时，应用倾向性评分匹配法控制混杂因素。结果   育龄期乳腺癌患者对子代健康和遗传风险担忧得分为（11.40±2.99）分；匹配前后不同子女健康亚量表得分分组的患者在癌症诊断前后生育意愿改变率的差异均不具有统计学意义（P＞0.05）。结论   育龄期乳腺癌患者对子代健康和遗传风险的担忧虽然没有显著影响其生育意愿的改变，但其对子代健康和遗传风险担忧处于较高水平，临床医护人员应提高对这一现象的重视，可通过多渠道科普相关知识，开展遗传咨询服务以减轻患者的担忧。

      Objective  To explore the current status of childbearing age breast cancer patients’  concerns  about their children’s health and genetic risk and its influence on the change of fertility intention before and after cancer diagnosis．Methods  From November 2019 to September 2020，the Chinese version of the Reproductive Concern After Cancer Scale（RCAC）- Children’s Health Sub-scale was used to interview 230 patients with breast cancer of childbearing age in a tertiary hospital in Guangzhou，and SPSS 26.0 and PSM plug-in were used to analyze the results statistically．The  propensity  score matching method was used to control confounding factors when comparing the change  rate of fertility intention of patients with low scores and those with medium and high scores in the children health subscale．Results  The score of concern for the health and genetic risk of children in breast cancer patients of childbearing age was（11.40±2.99）．There was no statistically significant difference in the change  rate of fertility intention before and after cancer diagnosis among patients with different subscale scores of children’s health．Conclusions   Despite not significantly impacting fertility intentions，the notably high level of concern regarding children’s health and genetic risks among childbearing-age breast cancer patients necessitates increased clinical awareness．It is recommended that healthcare professionals address this through multi-channel education and genetically focused counseling within a collaborative model to mitigate patient distress．

      目的 探讨一种保护型的上肢约束衣在儿童洗胃中的应用。方法   自制并获得实用新型专利“一种保护型的上肢约束衣”，包括背单和两条前襟连接单，三条可调节性约束带，以及下肢延伸固定。选取2023年1月—2023年12月在我院急诊科因急性中毒施行洗胃的患儿为研究对象，依据住院时间，将2023年1月—2023年6月收治患儿为对照组（58例），将2023年7月一2023年12月收治患儿为观察组（58例）。观察组使用本研究发明的保护型上肢约束衣进行约束，对照组则采用传统的约束方法。对两组患儿的洗胃时间、协助人员数量和重复置管次数进行了记录和比较。结果   观察组协助洗胃人数、洗胃时间、重复置管次数分别为1.00（1.00，1.00）人、28.00（26.00，32.00）min、0.00（0.00，0.00）次，均低于对照组的3.00（3.00，3.00）人、32.00（29.00，35.25）min、0.00（0.00，0.00）次，差异有统计学意义（P＜0.05）。结论   儿童洗胃中应用保护型上肢约束衣，能显著减少协助洗胃人数和重复置管次数，缩短洗胃时间，提高了洗胃效率。

       Objective  To explore the application of a protective upper extremity restraint in gastric lavage in children．Methods  A new patent for“A protective upper extremity restraint garment” was designed，which includes a back sheet and two front-flap connecting sheets，three adjustable restraint bands，and an extension fixation of lower extremity．From January 2023 to December 2023，children who underwent acute gastric lavage due to accidental ingestion in the emergency department of a hospital were selected as the research subjects，according to the admission date，the control group（58 cases）was selected from January 2023 to June 2023，and the observation group（58 cases）was selected from July 2023 to December 2023．The observation group was restrained by the protective upper extremity restraint garment，while the control group was restrained by the traditional restraint method．The time of gastric lavage，the number of assistants and the times of repeated intubation were recorded and compared between the two groups．Results  The gastric lavage assistance，lavage time，and number of repeated intubations in the observation group were 1.00［1.00，1.00］person，28.00［26.00，32.00］min，and 0.00［0.00，0.00］times，lower than in the control group（3.00［3.00，3.00］person，32.00［29.00，35.25］min，0.00［0.00，0.00］times），the differences were statistically significant（P＜0.05）．Conclusions  The application of a protective upper extremity restraint suit during pediatric gastric lavage significantly reduces the number of required assistants，decreases repeated intubation attempts，shortens lavage time，and enhances procedural efficiency．
