Objective:To explore the clinical efficacy and safety of a multimodal treatment regimen integrating radiotherapy, chemotherapy, and immunotherapy in patients with human epidermal growth factor receptor 2 (HER2) -negative locally advanced or advanced gastric cancer.Methods:A total of 34 patients with unresectable, HER2-negative, locally advanced or metastatic gastric/gastroesophageal junction (G/GEJ) adenocarcinoma admitted to the Affiliated Cancer Hospital of Guizhou Medical University from September 2021 to March 2024 were selected as study objects. Participants received one cycle of either XELOX regimen (capecitabine + oxaliplatin) or SOX regimen (S-1 + oxaliplatin) with immunotherapy (sintilimab or nivolumab) . The process was succeeded by radiotherapy targeted at the primary G/GEJ tumor and regional lymph nodes. In selected cases, sequential radiotherapy was also administered for distant metastases. The primary endpoint was objective response rate (ORR) , and secondary endpoints were disease control rate (DCR) , clinical symptom response, changes in Karnofsky performance status (KPS) score, progression-free survival (PFS) , and adverse reactions. Clinical efficacy was assessed in accordance with Response Evaluation Criteria in Solid Tumors version 1.1. Adverse reactions were assessed and graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0 and the Chinese Society of Clinical Oncology guidelines for management of immune checkpoint inhibitor-related toxicity. With a median follow-up of 7 months (range: 2.3 to 30 months) , the final evaluation considered the best response documented throughout follow-up. Survival curves were constructed utilizing Kaplan-Meier analysis.Results:By the end of follow-up, an overall ORR of 58.8% (20/34) and DCR of 70.6% (24/34) were observed. The ORR of lesions by radiotherapy reached 73.8% (48/65) and the DCR reached 92.3% (60/65) . Univariate analysis showed that the ORR of female patients (84.6%, 11/13) was higher than that of male patients (42.9%, 9/21) , and the ORR of patients with distant lymph node metastasis alone (83.3%, 15/18) was higher than that of patients with distant lymph node metastasis combined with organ metastasis or organ metastasis alone (18.2%, 2/11) , with statistically significant differences ( P=0.030; P=0.010) . There were no statistically significant differences in ORR among patients with different age ( P=0.487) , KPS score ( P=0.198) , primary tumor location ( P=0.280) , histological differentiation ( P=0.668) , chemotherapy regimen ( P=0.728) , or immunotherapy regimen ( P>0.999) . Twenty-two of 23 (95.7%) patients with upper abdominal pain were relieved, 10 of 21 (47.6%) patients with appetite loss were relieved, 15 of 17 patients with upper abdominal distension were relieved, 13 of 14 patients with melena were relieved, 6 of 7 patients with eating obstruction were relieved, 3 of 4 patients with metastatic site pain were relieved, and 2 patients with hematemesis were relieved. KPS score enhanced in 82.4% (28/34) of patients, remained stable in 11.8% (4/34) , and declined in 5.8% (2/34) . The median PFS of the 34 patients was 7.9 months. The most common adverse reactions during radiotherapy combined with chemotherapy and immunotherapy were hematological adverse reactions, in which neutropenia accounted for the highest proportion (91.2%, 31/34) , followed by anemia (50.0%, 17/34) . Fatigue was the most common non-hematological adverse reaction (50.0%, 17/34) , followed by nausea and vomiting (26.5%, 9/34) . The adverse reactions of 6 patients receiving immune monotherapy maintenance were anemia, hypothyroidism, transaminase elevation, proteinuria, fatigue, and rash, all of which were grade 1-2. Conclusions:Radiotherapy combined with chemotherapy and immunotherapy shows good short-term clinical efficacy in patients with HER2-negative locally advanced or advanced gastric cancer, and the overall adverse reactions are tolerable. Female or patients with distant lymph node metastasis alone may be the preferred population for this study protocol.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Objective:To explore the pattern of lymph node metastasis and prognosis in locally advanced gastric cancer after neoadjuvant immunotherapy combined with chemotherapy (NICT).Methods:This retrospective study included pathologically confirmed gastric adenocarcinoma (cT3-4aN+) patients who underwent radical resection after ≥2 cycles of PD-1 inhibitor-based chemotherapy with complete postoperative pathology. Exclusions: distant/other metastases, non-R0 resection, Her-2+ with targeted therapy, microsatellite instability, or esophagogastric junction cancer invading >1 cm into lower esophagus. From January 2020 to December 2024, a total of 343 consecutive gastric cancer patients who received NICT treatment were admitted to Tianjin Medical University Cancer Institute and Hospital. According to the above criteria, 324 cases were included in the lymph node metastasis analysis, and 302 cases were included in the survival analysis. The median age of all patients was 58 years, with 245 males (75.6%) and a median body mass index (BMI) of 22.9 kg/m2. There were 170 cases (52.5%) at T3 stage and 154 cases (47.5%) at T4a stage; the median number of cycles of neoadjuvant immunotherapy combined with chemotherapy was 3 cycles. The primary outcome measure was the positive lymph node metastasis rate (number of metastatic cases in the group / total number of dissected cases in the group×100%). A positive lymph node metastasis rate >10% was defined as high metastasis, and <5% as low metastasis. The secondary outcome measures were high-risk factors for lymph node metastasis and influencing factors related to patient prognosis. Lymph node grouping was performed according to the 8th edition of the American Joint Committee on Cancer (AJCC) guidelines. The positive lymph node metastasis rate was statistically analyzed by stratification based on surgical methods (total gastrectomy, proximal gastrectomy, distal gastrectomy). Multivariate analysis of risk factors for lymph node metastasis were performed with logistic regression analysis, and survival analysis were performed with the Kaplan-Meier method and Cox regression model.Results:The postoperative pathological complete response rate (pCR) of all patients was 21.0% (68/324), and the overall positive lymph node metastasis rate was 48.8% (158/324). A total of 150 patients underwent total gastrectomy, 42 underwent proximal gastrectomy, and 132 underwent distal gastrectomy.In the total gastrectomy group: the high metastasis subgroups were No.1 (19.3%, 29 cases), No.2 (14.7%, 22 cases), No.3 (28.0%, 42 cases), No.7 (12.7%, 19 cases), No.8a (16.0%, 24 cases), and No.9 (17.3%, 26 cases); the low metastasis subgroups were No.5 (4.7%, 7 cases), No.10 (3.3%, 5 cases), No.11d (1.3%, 2 cases), and No.12a (4.0%, 6 cases).In the proximal gastrectomy group: the high metastasis subgroups were No.3 (14.3%, 6 cases), No.7 (23.8%, 10 cases), and No.11p (11.9%, 5 cases); the low metastasis subgroups were No.4d (2.4%, 1 case) and No.10 (2.4%, 1 case).In the distal gastrectomy group: the high metastasis subgroups were No.3 (25.8%, 34 cases), No.6 (26.5%, 35 cases), No.7 (11.4%, 15 cases), and No.11p (11.4%, 15 cases); the low metastasis subgroups were No.4sb (3.8%, 5 cases) and No.12a (4.5%, 6 cases).Results of multivariate analysis showed that TRG grade (HR: 5.938, 95%CI: 3.028-11.646, P<0.001) was an independent factor affecting lymph node metastasis in patients with locally advanced gastric cancer after neoadjuvant immunotherapy combined with chemotherapy. The median follow-up time was 26.0 (6.0-54.3) months, and the 3-year overall survival (OS) of all patients was 78.1%. Results of multivariate Cox analysis showed that ypT (HR=1.744, 95%CI: 1.300-2.338, P<0.001), ypN (HR=1.998, 95%CI: 1.503-2.655, P<0.001), and postoperative complications (HR=1.913, 95%CI: 1.111-3.294, P=0.019) were independent factors affecting the overall survival of patients with locally advanced gastric cancer after neoadjuvant immunotherapy combined with chemotherapy. Conclusion:NICT significantly changes the pattern of lymph node metastasis in LAGC. ypT and ypN stages are core indicators for survival prognosis. The necessity of dissection for lymph node groups with a metastasis rate <5% needs to be carefully evaluated.

Objective:To investigate the clinical efficacy of antiperistaltic uncut Roux-en-Y anastomosis (Uncut RY) in laparoscopic distal gastrectomy (LDG) for gastric cancer (GC).Methods:The clinicpathological data of 309 patients who underwent LDG for GC between Jan 2020 to Dec 2021 in Tianjin Medical University Cancer Institute & Hospital were collected. Among them, 102 cases received antiperistaltic Uncut RY anastomosis, 96 cases did RY anastomosis, and 111 cases did B Ⅱ+Braun anastomosis. The general data and clinical efficacy were compared.Results:The operative time in Uncut RY group and B Ⅱ+Braun group was shorter than that in RY group ( F=3.356, P=0.036). The incidence of postoperative short-term complications was not statistically different among three groups ( P>0.05). Compared to Uncut RY group and RY group, the B Ⅱ+Braun group had a significantly higher incidences of reflux gastritis (19.8% vs. 6.9% vs.5.2%, F=13.889, P=0.001). The incidence of RY stasis syndrome in RY group (15.6%) was significantly higher than that in Uncut RY group (2.0%) and B Ⅱ+Braun group (2.7%) ( F=19.320 ,P=0.000). There were no significant differences in postoperative 1-year nutritional indexes among three group ( P>0.05). Conclusions:The antiperistaltic Uncut RY anastomosis in LDG for GC is safe and feasible, which can reduce the incidences of reflux gastritis and RY stasis syndrome.

Objective The aim of this study was to investigate the high risk factors of intraoperative stress injury in children with posterior spinal scoliosis and to construct a corresponding risk prediction model.Methods A total of 237 cases of orthopaedic surgery for posterior scoliosis performed in three first-class hospitals in Changsha City from October 2021 to February 2023.The patients were divided into injury group(31 cases)and uninjured group(206 cases)according to whether stress injury occurred.The risk factors were screened by single factor analysis and multiple Logistic regression analysis,and the corresponding risk prediction model was constructed.Results The results of single factor analysis showed that constitutional index,preoperative skin condition,preoperative hypoproteinemia,preoperative anemia,operative time,intraoperative body temperature and intraoperative bleeding were related to the occurrence of vascular crisis.BMI,preoperative skin condition,preoperative hypoproteinemia,operative time and intraoperative bleeding are high risk factors for the occurrence of intraoperative stress injury in children with posterior scoliosis.The area under ROC curve is 0.612,the sensitivity is 89.7％,and the specificity is 91.0％,indicating that this model has good risk prediction ability.Conclusion BMI,preoperative skin condition,preoperative hypoproteinemia,operative time and intraoperative bleeding are high risk factors for the occurrence of intraoperative stress injury in children with posterior scoliosis.

Objectives:To investigate the association of trajectories of atherogenic index of plasma(AIP)with the risk of atherosclerotic cardiovascular disease(ASCVD). Methods:A total of 51 831 employees and retirees who participated in Kailuan Group health examination for three consecutive times from 2006 to 2010 were included in this study.AIP was calculated using the log(triglycerides[TG]/high-density lipoprotein-cholesterol[HDL-C])formula.AIP trajectory models were fitted by the SAS Proc Traj program,and according to AIP trajectory,the subjects were divided into low stability group(n=11 114),low to moderate stability group(n=21 647),medium to high stability group(n=13 659),and high stability group(n=5 411).Kaplan-Meier method was used to calculate the cumulative incidence of ASCVD in different groups and compared by log-rank test.Cox proportional risk regression model was used to analyze the effects of different AIP trajectories on ASCVD risk. Results:Finally,51 831 patients were included in the analysis.During a mean follow-up of(10.19±2.22)years,5 142(9.92%)subjects developed ASCVD,4 013(7.74%)subjects died.Cox regression analysis after adjusting for confounding factors showed:compared with the low stability group,the risk of ASCVD increased by 13%(HR=1.13,95%CI:1.04-1.23,P=0.003)and 20%(HR=1.20,95%CI:1.10-1.31,P＜0.001)and 41%(HR=1.41,95%CI:1.27-1.57,P＜0.001)in the low to moderate stability group,moderate to high stability group and high stability group,respectively,and the risk increased gradually(Ptrend＜0.001).Stratified analysis showed that the risk of ASCVD in people aged＜65 years and low-density lipoprotein cholesterol(LDL-C)＜3.4 mmol/L with long-term high levels of AIP was higher than that in people aged≥65 years and LDL-C≥3.4 mmol/L(both Pinteraction＜0.01). Conclusions:In Kailuan Study cohort,those with long-term high levels of AIP had a higher risk of ASCVD,and the risk gradually increased.In addition,we found that the risk of ASCVD in people with long-term high levels of AIP was higher in＜65 years old than in≥65 years old,and the risk of ASCVD in people with LDL-C＜3.4 mmol/L was higher than that in people with LDL-C≥3.4 mmol/L.
