Objective:To analyze the impact of lymph node dissection on textbook outcomes (TO) and the prognosis of intrahepatic cholangiocarcinoma (ICC).Methods:The retrospective cohort study was conducted. The clinicopathological data of 376 ICC patients who underwent hepatectomy in 4 medical centers, including Mengchao Hepatobiliary Hospital of Fujian Medical University et al, from December 2011 to December 2017 were collected. There were 242 males and 134 females, aged 57(range, 48-63)years. According to the criteria of TO, patients were classified as two cate-gories, including patients achieving TO and not achieving TO. Measurement data with normal distri-bution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M(range) or M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were represented as absolute numbers, and comparison between groups was conducted using the chi-square test, Yates adjusted chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the non-parameter rank sum test. Univariate and multivariate analyses were conducted using the Logistic regression model. The Kaplan-Meier method was used to draw survival curve. Survival analysis was conducted using the Log-rank test. Results:(1) TO situations. Of the 376 ICC patients who underwent hepatectomy, 199 cases achieved TO, including 40 cases with lymph node dissection and 159 cases without lymph node dissection, 177 cases did not achieve TO, including 76 cases with lymph node dissection and 101 cases without lymph node dissection. (2) Influencing factors for TO after hepatectomy of ICC patients. Results of multivariate analysis showed that lymph node dissection, microvascular invasion, nerve invasion and the volume of intraoperative blood loss >800 mL were independent risk factors for achieving TO after hepatec-tomy of ICC patients ( odds ratio=2.22, 2.95, 3.58, 4.09,95% confidence interval as 1.34-3.69, 1.43-6.07, 1.40-9.17, 1.35-12.43, P<0.05). Of the 116 patients with lymph node dissection, 40 cases achieved TO, 103 cases achieved R 0 resection, 38 cases had postoperative complications, 67 cases had delayed hospital stay. The above indicators were 159, 255, 41, 65 of 260 patients without lymph node dissection. There were significant differences in the above indicators between patients with and without lymph node dissection ( χ2=22.90, 15.16, 13.95, 37.78, P<0.05). (3) Follow-up. All the 376 patients were followed up for 19(range, 1-74)months. Of 199 patients achieving TO, the 1-, 2-and 3-year survival rates of 40 patients with lymph node dissection were 54.0%, 36.6% and 26.1%, respectively, versus 67.7%, 42.7% and 34.4% of 159 patients without lymph node dissection, showing no significant difference between them ( χ2=1.89, P>0.05). Of 177 patients not achieving TO, the 1-, 2-and 3-year survival rates of 76 cases with lymph node dissection were 58.9%, 25.7% and 10.3%, respectively, versus 53.0%, 28.5% and 17.2% of 101 cases without lymph node dissection, showing no significant difference between them ( χ2=0.25, P>0.05). Conclusions:Lymph node dissec-tion, microvascular invasion, nerve invasion and the volume of intraoperative blood loss >800 mL are independent risk factors for achieving TO after hepatectomy of ICC patients. Lymph node dissec-tion may increase the postoperative complication rate, prolong the hospital stay and decrease the rate of achieving TO. However, it does not affect the prognosis of patients.

Objective:To understand the cognition of the family caregivers of terminal cancer patients on digital health intervention, to clarify their actual needs, and to analyze the obstacles to their acceptance of digital health intervention, so as to develop a digital health intervention plan for the family caregivers of terminal cancer patients.Methods:From February 2024 to March 2024, the family caregivers of 16 patients with terminal cancer in Hunan Cancer Hospital Pain Hospice Ward were selected by objective sampling, who met the inclusion and exclusion criteria were interviewed in a semi-structured manner about the cognition and needs of digital health intervention, and the interview contents were sorted and analyzed using the Colaizzi7 step method.Results:A total of 16 family caregivers of terminal cancer patients, 4 males and 12 females, aged 26-55 years, were interviewed. Four themes were distilled from the interview results: family caregivers of terminally cancer patients agree on the importance of digital health interventions; lack of awareness of digital health interventions; expectations of digital health interventions; and possible confounders affecting digital health interventions.Conclusions:The family caregivers of terminal cancer patients had insufficient awareness of digital health intervention, but all showed affirmation of the development of digital health intervention services. It is recommended to actively improve the basic conditions of digital health services, strengthen publicity, raise the level of awareness of the family caregivers, and positively overcome the relevant interfering factors, so as to gradually promote the development of digital health services.

Biliary tract carcinoma exhibits high heterogeneity at the genomic,epigenetic,and molecular expression levels.The patients even with the same pathological morphology and clinical stage of biliary tract malignant tumors have substantial differences in the treatment response and prognosis.Traditional pathological histology and clinical classifications are no longer sufficient to meet the demands of the precision medicine era.Molecular subtyping has the potential to provide more personalized cancer treatment strategies.It not only helps to reveal the mechanisms of tumor development and accurately predict disease prognosis,but also plays a crucial role in guiding the development of novel targeted drugs and implementing targeted therapies for specific tumors.With the ongoing development of precision medicine,the role of molecular subtyping in cancer diagnosis,treatment option,and prognosis assessment is increasingly prominent.This paper systematically reviewed the recent progress in the molecular subtyping of biliary tract malignant tumors based on domestic and international clinical and basic research.

Objective To establish and validate a Nomogram model for predicting the overall survival(OS)of the patients with intrahepatic cholangiocarcinoma(ICC)based on domestic multicenter data,and screen the beneficiaries of adjuvant chemotherapy based on the prediction model.Methods From December 2011 to December 2017,the data of 278 patients with postoperative pathological diagnosis of ICC from 4 medical centers in our country were collected retrospectively COX regression model was used to screen the independent risk factors of OS and constructed a Nomogram model.This model was used to stratify the risk of OS for all patients and to screen the beneficiaries of adjuvant chemotherapy.Results A total of 278 patients were enrolled,and 23 cases(8.3%)received adjuvant chemotherapy.COX multivariate analysis showed that drinking history,ECOG score,method of hepatectomy,lymph node status,number of tumors,and tumor differentiation were independent risk factors for postoperative OS.The Nomogram model had a C-index of 0.690(95%CI:0.646-0.734)in the training cohort and 0.740(95%CI:0.863-0.617)in the validation cohort.According to risk stratification by Nomogram model,in the high-risk group there was a statistically significant difference in survival between adjuvant chemotherapy and non-adjuvant chemotherapy(P=0.033),whereas in the low-risk group,there was no significant difference in survival(P=0.59).Conclusions Nomogram model based on independent risk factors of OS demonstrated excellent predictive capability for survival and could be used to screen,and identify the patients with ICC who benefit from adjuvant chemotherapy.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To investigate the effects of 0.5 Gy 60Co γ-ray irradiation on intestinal tissue injury and intestinal microflora in mice.Methods C57BL/6N mice were irradiated with 0.5 Gy 60Co γ-ray at 1 d,3 d,7 d and 14 d after irradiation.Jejunum tissues were fixed and frozen,and feces were frozen.Hematoxylin-eosin staining was used to observe the pathological injury to jejunum after irradiation,ki67 immunohistochemical staining was adopted to detect the proliferation of jejunum crypt cells,and TdT-mediated dUTP nick end labeling was employed to detect the apoptosis of jejunum crypt cells.The expressions of TNF-α,IL-1β,IL-6 and IL-10 cytokines in small intestines were detected via radioimmunoassay.The changes of intestinal flora in mice after irradiation were analyzed by metagenomic sequencing,and LEfSe analysis and ROC analysis were used to screen the bacteria with significant differences.Results After 0.5 Gy 60Co γ-ray irradiation,the proliferative cells of the jejunal crypt were significantly decreased at 1 d after irradiation(P＜0.05),while the apoptotic cells were significantly increased at 1 and 3 d after irradiation(P＜0.01).The expression of TNF-α at 7 and 14 d after irradiation,that of IL-1 β at 1,3,7 and 14 d after irradiation and that of IL-6 at 3,7 and 14 d after irradiation were significantly increased(P＜0.05),while the expression of IL-10 at 7 and 14 d after irradiation was significantly decreased(P＜0.05).After 0.5 Gy 60Co γ-ray irradiation,intestinal flora composition changed significantly at phylum,genus and species levels,and Lactobacillus murinus,Lactobacillus johnsonii,Alistipes-unclassified,Mucispirillum schaedleri underwent the most significant changes and had higher LDA scores.Conclusion The whole body irradiation of 0.5 Gy 60Co γ-ray can cause intestinal tissue damage and change the composition of intestinal flora in mice.

Objective: : The spontaneous intracerebral hemorrhage (ICH) remains a significant cause of mortality and morbidity throughout the world. The purpose of this retrospective study is to develop multiple models for predicting ICH outcomes using machine learning (ML). Methods: : Between January 2014 and October 2021, we included ICH patients identified by computed tomography or magnetic resonance imaging and treated with surgery. At the 6-month check-up, outcomes were assessed using the modified Rankin Scale. In this study, four ML models, including Support Vector Machine (SVM), Decision Tree C5.0, Artificial Neural Network, Logistic Regression were used to build ICH prediction models. In order to evaluate the reliability and the ML models, we calculated the area under the receiver operating characteristic curve (AUC), specificity, sensitivity, accuracy, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR). Results: : We identified 71 patients who had favorable outcomes and 156 who had unfavorable outcomes. The results showed that the SVM model achieved the best comprehensive prediction efficiency. For the SVM model, the AUC, accuracy, specificity, sensitivity, PLR, NLR, and DOR were 0.91, 0.92, 0.92, 0.93, 11.63, 0.076, and 153.03, respectively. For the SVM model, we found the importance value of time to operating room (TOR) was higher significantly than other variables. Conclusion : The analysis of clinical reliability showed that the SVM model achieved the best comprehensive prediction efficiency and the importance value of TOR was higher significantly than other variables.
