Objective:To establish and validate a preoperative differentiateon model of intrahepatic cholangiocarcinoma (ICC) and combined hepatocellular carcinoma (CHC) based on the inflammatory markers and conventional clinical indicators.Methods:The clinical data of 116 patients with ICC or CHC admitted to Henan Provincial People's Hospital from January 2018 to March 2023 were retrospectively analyzed, including 74 males and 42 females, aged (58.5±9.4) years old. The data of 83 patients were used to establish the differentiation model as the training group, including 50 cases of ICC and 33 cases of CHC. The data of 33 patients were used to validate the model as the validation group, including 20 cases of ICC and 13 cases of CHC. The clinical data including the platelet-to-lymphocyte ratio (PLR), systemic immune inflammation index (SII), prognostic inflammatory index (PII), prognostic nutritional index (PNI), neutrophil-to-lymphocyte ratio (NLR) and lymphocyte-to-monocyte ratio (LMR) were collected and analyzed. The receiver operating characteristic (ROC) curve was used to analyze the best cut-off values of PLR, SII, PII, PNI, NLR and LMR. Univariate and multivariate logistic regression analysis were used to determine the differential factors between ICC and CHC. The R software was used to draw the nomogram, calculate the area under the curve (AUC) to evaluate the model accuracy, and draw the calibration chart and the decision curve to evaluate the predictive efficacy of the model.Results:Univariate logistic regression analysis showed that liver cirrhosis, history of hepatitis, alpha fetoprotein, carbohydrate antigen 199, gamma-glutamyltransferase (GGT), PLR, PNI and inflammation score (IS) could be used to differentiate ICC from CHC (all P<0.05). The indicators identified in univariate analysis were included in multivariate logistic regression analysis. The results showed that absence of liver cirrhosis, GGT>60 U/L, PNI>49.53, and IS<2 indicated the pathology of ICC (all P<0.05). Based on the above four factors, a nomogram model was established to differentiate the ICC and CHC. The AUC of ROC curve of the nomogram model in the training and validation groups were 0.851 (95% CI: 0.769-0.933) and 0.771 (95% CI: 0.594-0.949), respectively. The sensitivities were 0.760 and 0.750, and the specificities were 0.818 and 0.769, respectively. The calibration chart showed that the predicted curve fitted well to the reference line. The decision curve showed that the model has a clear positive net benefit. Conclusion:The nomogram model based on inflammatory markers showed a good differentiation performance of ICC and CHC, which could benefits the individualized treatment.

Objective:To investigate the influence of different injection time of carbon nanoparticle tracer on the acquisition of lymph nodes in adenocarcinoma of esophagogastric junc-tion (AEG) treated by neoadjuvant chemoradiotherapy (nCRT) combined with surgical resection.Methods:The prospective randomized controlled study was conducted. The clinicopathological data of 120 AEG patients who were treated by nCRT combined with surgical resection in the Fourth Hospital of Hebei Medical University from March 2020 to March 2021 were selected. Based on random number table, patients were allocated into two groups. Patients undergoing endoscopic injection of carbon nanoparticle tracer 24 hours before nCRT were allocated into the experiment group, and patients undergoing endoscopic injection of carbon nanoparticle tracer 24 hours before surgical resection were allocated into the control group. All patients received the same plan of nCRT combined with D 2 radical gastrectomy. Observation indicators: (1) grouping situations of the enrolled patients; (2) surgical and postoperative pathological situations; (3) postoperative complications and treatment. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the independent sample t test. Measurement date with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was analyzed using the chi-square test. Comparison of ordinal data was analyzed using the non-parameter rank sum test. Results:(1) Grouping situations of the enrolled patients. A total of 120 patients were selected for eligibility. There were 85 males and 35 females, aged (60±9)years. There were 60 patients in the experiment group and 60 patients in the control group, respectively. (2) Surgical and postoperative pathological situations. Patients in the two groups underwent D 2 radical gastrectomy successfully, with R 0 resection. The number of lymph nodes harvest, the number of lymph nodes stained, the number of metastatic lymph nodes stained, the number of micro lymph nodes, the number of inferior mediastinal lymph nodes, the number of inferior mediastinal lymph nodes stained, cases in postoperative pathological stage N0, stage N1, stage N2, stage N3a were 40.6±13.9,20.1±7.7, 1.0(0,3.0), 8.1±2.8, 3.7±1.3, 2.0(1.0,2.0), 18, 13, 23, 6 in patients of the experiment group, respectively. The above indicators were 30.4±8.3, 12.7±3.5, 0(0,1.0), 6.2±2.0, 2.4±1.2, 1.0(0,1.0), 23, 21, 15, 1 in patients of the control group, respectively. There were significant differences in the above indicators between the two groups ( t=-5.01, 6.85, Z=-3.78, t=-4.04, -5.57, Z=-5.48, -2.12, P<0.05). (3) Postoperative complications and treatment. There were 5 cases of the experiment group and 7 cases of the control group with postoperative complications, showing no significant difference between the two groups ( χ2=0.37, P>0.05). The patients with postoperative complications were improved after symptomatic treatment. Conclusion:Compared with injection of carbon nanoparticle tracer 24 hours before surgical resection, injection of carbon nanoparticle tracer 24 hours before nCRT can improve the acquisition of lymph nodes in AEG treated by nCRT combined with surgical resection.

The combination of standardized D2 lymph node dissection and lymph node sorting after surgery can improve the survival of patients with gastric cancer and increase the accuracy of staging. With the development of different lymphatic tracers, individualized lymphatic navigation has become a new technical breakthrough in minimally invasive surgery for gastric cancer. Lymph node tracing is an important method to improve the quality of intraoperative lymph node dissection and correct the postoperative pathological stage. This article reviews the application status and progress of lymphatic navigation technology.

Objective:To explore the risk factors of lymphatic fistula after radical gastric cancer operation.Methods:We retrospectively analyze the clinicopathological data of gastric cancer patients who underwent radical surgery from May, 2019 to May, 2020 at the Third Department of Surgery, Fourth Hospital of Hebei Medical University, and analyze the risk factors impacting postoperative lymphatic leakage,for the establishment of the risk prediction scoring model.Results:A total of 487 patients with gastric cancer underwent radical gastrectomy, of which 32 patients (6.6%) had lymphatic leakage . Multivariate logistic regression analysis showed that hypoproteinemia before surgery (95% CI: 1.222-7.357, P=0.016), the lesion is located in the cardia-fundus of the stomach (95% CI: 1.117-6.788, P=0.028),stage T3-T4 (95% CI: 1.149-25.676, P=0.033), operation time ≥4 h (95% CI: 1.469-11.480, P=0.007), combined organ resection (95% CI: 1.106-12.886, P=0.034), D2+ lymph node dissection (95% CI: 1.969-11.510, P=0.001), anemia (95% CI: 1.271-9.392, P=0.015) were an independent risk factors. Equation based on multi-factor Logistic regression: logit( P)=-9.624+1.098×X 1+1.013×X 2+1.692×X 3+1.413×X 4+1.328×X 5+1.560×X 6+1.240×X 7 was estaslished, using Hosmer. Lemeshow test detects the goodness of fit of the regression equation ( P=0.348). The area under the ROC curve was 0.856 (95% CI: 0.787-0.926, P<0.001); the probability of lymphatic leakage when scores ≥4 points was 14.1%, when scores <4 points ,the probability of leakage was 2.5%. Conclusion:A risk prediction scoring model for lymphatic leakage after radical gastrectomy, can identify patients with high risk after surgery

Objective:To investigate the clinical value of systemic immune-inflammation index (SII) based on peripheral blood neutrophils, lymphocytes and platelets counts in predicting the prognosis of patients with gastric cancer after radical resection.Methods:From January 1, 2012 to January 1, 2015, the data of 2 273 patients with gastric cancer who underwent radical surgery at the Third Department of Surgery of the Fourth Hospital of Hebei Medical University were retrospectively analyzed. SII value was calculated according to the formula (SII=neutrophil cell count (×10 9/L)×platelet cell count (×10 9/L)/lymphocyte count (×10 9/L)). According to receiver operating characteristic curve (ROC), the optimal cut-off value of SII was determined and the patients were divided into high SII group and low SII group. Chi-square test was used to compare the clinicopathological characteristics and prognosis of the two groups. Kaplan-Meier method was applied to draw survival curve, log-rank test was used for univariate survival analysis, and Cox regression model was used for multivariate survival analysis. The ROC of preoperative SII, pathological TNM stage and their combination for predicting prognosis and recurrence were drawn, and the area under the curve (AUC) values were calculated to compare the predictive power of the three. Results:According to the ROC, the optimal cut-off value of SII was 589.5, and there were 1 180 cases (51.91%) in the high SII (SII≥589.5) group and 1 093 cases (48.09%) in the low SII (SII<589.5) group. Compared with those of the low SII group, the maximum diameter of gastric cancer in the high SII group was mostly ≥5 cm (49.04%, 536/1 093 vs. 56.27%, 664/1 180), the histological types were mostly poorly differentiated to undifferentiated (55.63%, 608/1 093 vs. 61.19%, 722/1 180), the depth of tumor invasion was mainly from T4a to T4b (45.11%, 493/1 093 vs. 54.837%, 647/1 180), and the rate of lymph node metastasis, pathological TNM stage, rate of vascular infiltration, incidence of nerve invasion, Ki-67 expression level, serum carcinoembryonic antigen level and carbohydrate antigen 19-9 level in the high SII group were all higher than those in the low SII group (67.70%, 740/1 093 vs. 80.68%, 952/1 180; 57.64%, 630/1 093 vs. 71.10%, 839/1 180; 55.54%, 607/1 093 vs. 67.03%, 791/1 180; 53.89%, 589/1 093 vs. 64.32%, 759/1 180; 45.29%, 495/1 093 vs. 56.69%, 669/1 180; 56.91%, 622/1 093 vs. 63.20%, 734/1 180; 53.25%, 582/1 093 vs. 57.97%, 684/1 180), and the differences were statistically significant ( χ2=8.842, 11.097, 7.225, 21.467, 50.200, 44.984, 31.687, 25.594, 29.549, 6.612 and 5.119, all P<0.05). The 5-year overall survival rate and disease-free survival rate of the low SII group were 75.66% and 67.61%, respectively, which were both higher than those of the high SII group, (24.92% and 23.31%, respectivily), the differences were statistically significant ( χ2=620.700 and 413.00, both P<0.01). The results of multivariate Cox regression analysis showed that tumor histological type, depth of invasion, pathological TNM stage, vascular invasion and preoperative SII were independent risk factors for postoperative prognosis and recurrence of patients with gastric cancer (odds ratios were 4.126, 2.255, 5.123, 3.826, 6.126, 4.683, 2.472, 5.224, 4.416, 6.212, respectively; 95% confidence interval 2.123 to 9.721, 1.632 to 7.427, 3.325 to 10.211, 2.321 to 9.322, 4.127 to 13.782, 2.561 to 9.418, 1.322 to 6.289, 3.315 to 11.526, 2.213 to 9.382, 4.474 to 13.541; all P<0.05). The predictive power of preoperative SII (AUC=0.842, 0.815) and pathological TNM stage (AUC=0.881, 0.827) for the 5-year overall survival and disease-free survival of patients with gastric cancer after radical resection was similar, however the predictive power of combination of the two (AUC=0.943, 0.895) was higher than that of preoperative SII and pathological TNM stage alone. Conclusions:Preoperative SII is an independent risk factor for the prognosis of patients with gastric cancer after radical resection, combined with parthological TNM stage can be used as an indicator to predict the prognosis and recurrence of patients.

BACKGROUND: Childhood adversities pose deleterious consequences on health and well-being, but limited studies explore whether unique patterns of adverse childhood experiences (ACEs) impact the mental health of emerging adults and the mediating role of current stressful events (CSEs). This study examined classes of ACEs and how they relate to CSEs, psychological distress, and subjective well-being among Eritrean College undergraduates. METHODS: Cross-sectional data on ACEs, CSEs, symptoms of psychological distress, and subjective well-being were collected from a national sample of college students (N = 507). We identified ACE patterns using latent class analysis and further examined whether CSEs mediated the effects of ACE classes on psychological distress and subjective well-being. RESULTS: 86.4% of the sample experienced at least one ACE. Collective violence, domestic violence, and physical abuse were the most common ACEs. Three subgroups, low ACEs (66.3%), household violence (19.1%), and multiple ACEs (14.6%) were identified. We found that relative to low ACEs, household violence (β = 0.142, 95% CI 0.046, 0.248) and multiple ACEs (β = 0.501, 95% CI 0.357, 0.666) indirectly influenced psychological distress through CSEs, and CSEs mediated the relationships between household violence (β = -0.096, 95% CI -0.176, -0.033), multiple ACEs (β = -0.338, 95% CI -0.498, -0.210), and subjective well-being. However, there were nonsignificant relative direct effects of ACE patterns on both psychological distress and subjective well-being. CONCLUSIONS Experiencing multiple ACEs and household violence in conjunction with CSEs significantly predict psychological distress and subjective well-being. Contextual interventions for the early identification of ACEs and the management of CSEs may play a crucial role in the prevention of mental health problems.

Objective:To explore the clinico-pathological characteristics and risk factors affecting prognosis in elderly patients with gastric cancer.Methods:A retrospective study was used to retrospectively analyze 2386 patients with gastric cancer undergoing radical surgery in Surgery Department of the Fourth Hospital of Hebei Medical University from 1 January 2012 to 1 January 2015.Patients aged 70 years and older were screened so as to analyze clinical characteristics and influencing factors for the prognosis.Results:A total of 2386 patients with gastric cancer were divided into the elderly group aged 70 years and older(342 of 2386 cases, 14.3%). There were statistically significant differences between the two groups in gender, number of concomitant diseases, NRS2002 score, PG-SGA score, tumor location, tumor diameter, histological type, Borrmann classification, tumor invasion depth staging(pT), lymph node metastasis staging(pN), the anatomic extent of tumor staging(TNM, pTNM), and Lauren classifications( P<0.05). The 981 of 2386 cases(41.4%)had postoperative complications, accompanied by 413 cases(17.3%)of surgery-related complications and 568 cases(24.0%)of non-surgery-related complications.A multivariate logistic analysis showed that the number of preoperative co-existing diseases ≥ 2 was an independent influencing factor for postoperative complications in elderly gastric cancer patients( HR=4.478, 95% CI: 1.121-7.918, P=0.006). The 5-year OS and DSS was 21.10% and 62.73% in the ≥70 years gastric cancer group, and was 54.1% and 70.0% in the <70 years gastric cancer group, respectively.The difference in the 5-year OS between the two groups was statistically significant( P<0.05), while the difference in the 5-year DSS between the two groups was not statistically significant( P>0.05). Multivariate analysis by the Cox proportional hazard model showed that the independent risk factors for the prognosis of elderly patients with gastric cancer included the low-undifferentiated histological type of the tumor( P=0.004), the depth of tumor invasion pT stage of pT4a-pT4b( P=0.007), lymph node metastasis( P=0.034), tumor pTNM stage ⅢA-ⅢC( P=0.002)and vascular tumor thrombus( P=0.034). Conclusions:Elderly patients with gastric cancer have many preoperative co-existing diseases, which increases the risk of postoperative non-surgical complications.Therefore, we should focus on the peri-operative management of their comorbid diseases so as to improve the safety and efficacy of surgery.The advanced age is not the independent risk factors for the prognosis.

Objective:To investigate the clinically relevant factors of progressive disease (PD) after neoadjuvant therapy for locally advanced gastric cancer.Methods:From Jun 2011 to Mar 2016, 569 patients with locally advanced gastric cancer(cT3/4N0/+ M0) admitted to the Fourth Hospital of Hebei Medical University were retrospectively analyzed .Results:All 569 patients completed neoadjuvant therapy, 59 patients (10.4%) had PD. Univariate analysis showed that tumor size (χ 2=10.091, P=0.001), pathological type (χ 2=4.110, P=0.043), Borrmann type (χ 2=91.941, P=0.001), pre-treatment cT stage (χ 2=7.980, P=0.005) were associated with PD after neoadjuvant therapy for gastric cancer. The results of multi-factor regression analysis showed that pathological type, Borrmann type, pre-treatment cT stage were independent factors influencing the occurrence of PD after neoadjuvant therapy for advanced gastric cancer. The overall survival and progression-free suruival time of patients with PD is significantly shorter than that of patients without PD . Conclusion:The pathological type, Borrmann typing and pre-treatment cT stage are the influencing factors for the occurrence of PD after neoadjuvant treatment in advanced gastric cancer, and the prognosis of PD patients is poor.
