Couinaud first proposed the naming of S9 segment of liver in 1994, and Liu Yunyi further promoted this naming in his work “Applied Anatomy of Hepatectomy and Liver Transplantation” in 2016. However, it has not been widely recognized and supported in the field of liver surgery for a long time. In recent years, due to the promotion and gradual maturity of endoscopic technology, there has been a more detailed understanding and demand for anatomy of liver and bile duct. Therefore, this article further explores the clinical value and significance of S9 segment of liver.
Lung cancer ranks among the most prevalent and lethal malignancies globally. Its prognostic outcomes are not only contingent upon tumor characteristics and therapeutic interventions but also intricately linked to the nutritional and immune profiles of patients. This article conducts a thorough review of both domestic and international research, providing a comprehensive synthesis of the prognostic value of widely investigated nutritional and immune indicators in the context of lung cancer. The primary objective is to identify optimal prognostic markers in clinical practice, offering guidance for precise post-treatment assessment and early intervention for lung cancer patients.
ObjectiveThe diagnostic efficacy of long non-coding RNA (lncRNA) for tuberculosis was evaluated by systematic review. MethodsData from PubMed, Web of Science, Cochrane Library, Embase, CMJFD, CNKI and WanFang Data were searched. Literatures on the diagnostic value of lncRNA in tuberculosis from the database establishment to August 20, 2024 were selected, and the quality of literatures was assessed using QUADAS-2 tool. Meta-Disc 1.0 software tested the threshold heterogeneity of the included studies. Stata 18.0 software calculated sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnostic odds ratio and other effect sizes, and performed subgroup analysis and meta regression to explore the source of heterogeneity. Deeks funnel plot evaluates publication bias. Results A total of 28 case-control studies were included in 14 literatures. The meta-results showed that the combined sensitivity was 0.88 (95%CI 0.81 to 0.93), the specificity was 0.90 (95%CI 0.84 to 0.94), and the PLR was 9.05 (95%CI 5.16 to 15.87). The NLR and DOR were 0.13 (95%CI 0.08 to 0.22) and 67.96 (95%CI 27.27 to 169.39), and the AUC were 0.95 (95%CI 0.93 to 0.97). Subgroup analysis showed that lncRNA was more effective in the diagnosis of tuberculosis when PMBC samples, lncRNA expression was down-regulation, the study sample size was ≤100, there was cut-off value, GAPDH was used as the internal reference, and RNA extraction kit was used. meta regression indicated that lncRNA expression level and sample size were the main sources of heterogeneity. Conclusion LncRNA has high accuracy in the diagnosis of tuberculosis, and is expected to become a new biomarker to assist the diagnosis of tuberculosis.
ObjectivesTo systematically review the necessary factors of questionnaires design on patients' values and preferences in order to provide information on the most appropriate questionnaires when developing clinical practice guidelines.MethodsA systematic literature search of PubMed, EMbase, The Cochrane Library, CBM, CNKI and WanFang Data databases was performed to identify studies on questionnaires evaluating patient values and preferences. The authors included the articles that used fully structured questionnaires or scales with standardized questions and answer options. We assessed the questionnaires' construction with psychometric methodology and summarized the necessary factors on patients' preferences and values into the domains and items.ResultsTwenty articles were eventually included. Five out of 20 studies (25%, 5/20) described the process of item generation while merely one questionnaire (5%, 1/20) mentioned pilot testing. Regarding validity, there were 6 questionnaires (30%, 6/20) that assessed validity. For acceptability, the time taken to complete the questionnaires range from 10 to 30 minutes and only 6 studies reported response rates. The results showed that the factors affecting the design of questionnaires on patients' values and preference were related to the effectiveness, safety, prognostic factors and others. The main factors were the effects, side effects and risk of complications, risk of relapse and the cost of treatments.ConclusionsOnly a few studies have developed questionnaires with rigorous psychometric methods to measure patients' preference and values. There is still no valid or reliable questionnaires for patients' preference and values when developing clinical practice guidelines. Further study should be conducted to develop standardized instruments to measure patients' preference and values. It is suggested that the factors this study provides can be used in formulating questionnaires on patients' preference and values.
ObjectiveTo systematically review clinical value of des-γ-carboxy prothrombin (DCP) in the diagnostic of primary hepatocellular carcinoma (PHC).MethodsDatabases including PubMed, The Cochrane Library, EMbase, Medline (Ovid), CNKI, VIP, WanFang Data and CBM were electronically searched to collect relevant studies on DCP in the diagnosis of PHC from inception to December 31st, 2018.

ObjectiveTo evaluate the value of 120 kV portal venous phase images combined with iodine maps created from dual-source dual-energy CT (DECT) for the diagnosis of pancreatic necrosis in the early stage of acute pancreatitis. MethodsThis prospective study enrolled 17 patients who underwent abdominal dual-source DECT within 72 hours from the onset of acute pancreatitis. All patients had received treatment in West China Hospital from May 2014 to August 2014. Comparison of the diagnostic value of 120 kV portal venous phase images alone and 120 kV portal venous phase images combined with iodine maps created from dual-source DECT was performed. ResultsSix of the 17 patients were found the presence of pancreatic necrosis (4 patients without obvious necrosis in the early stage developed to pancreatic necrosis, and 2 patients with the presence of necrosis in the early stage improved). The sensitivity, specificity, and accuracy of 120 kV portal venous phase images for the diagnosis of pancreatic necrosis were 50.0% (3/6), 100% (11/11), and 82.4% (14/17), respectively, and it had a good diagnostic value (AUC=0.856, P=0.018). The sensitivity, specificity, and accuracy of 120 kV portal venous phase images combined with iodine maps created from dual-source DECT for predicting pancreatic necrosis were 100% (6/6), 90.9% (10/11), and 94.1% (16/17), respectively, and this method had good value too (AUC=0.977, P=0.002), which higher than that of 120 kV portal venous phase images (P=0.002). ConclusionsThe 120 kV portal venous phase images combined with iodine maps created from dual-source DECT is helpful to improve subjective judgment in the diagnosis of pancreatic necrosis in the early stage of acute pancreatitis. It also contributes to the display of hypo-perfusion area of the pancreatic parenchyma, and has higher diagnostic value.
Objective To investigate the relationship between preoperative hemoglobin, albumin, lymphocyte and platelet (HALP) score, and clinicopathologic features of colon cancer, and to analyze the predictive value of HALP score for postoperative liver metastasis. Methods The clinical data of 163 patients with colon cancer admitted to the 909th Hospital of Joint Logistic Support Force (Dongnan Hospital of Xiamen University) from January 2018 to December 2019 were retrospectively analyzed. According to the occurrence of postoperative liver metastasis, the patients were divided into metastatic group (n=35) and non-metastatic group (n=128). The correlation between preoperative HAPL score and clinicopathologic features of colon cancer was analyzed. The predictive value of HALP score for postoperative liver metastasis of colon cancer was analyzed by using receiver operating characteristic (ROC) curve. The risk factors of liver metastasis after colon cancer surgery were analyzed by using univariate and multivariate logistic analysis. Kaplan-Meier risk curve was drawn, and log-rank test was used to analyze the predictive value of different HALP score for postoperative liver metastasis. Results HALP score were decreased in patients with maximum tumor diameter ≥5 cm, preoperative carcinoembryonic antigen (CEA) ≥5 μg/L, serous membrane and extrasserous infiltration, lymph node metastasis and vascular invasion, and the difference was statistically significant (P<0.05). Multivariate logistic regression analysis showed that HALP score [OR=1.467, 95%CI (1.253, 1.718), P<0.001], maximum tumor diameter [OR=3.476, 95%CI (1.475, 5.358), P=0.013], preoperative CEA level [OR= 6.197, 95%CI (2.436, 6.248), P=0.005], and lymph node metastasis [OR=2.593, 95%CI (1.667, 6.759) , P=0.003] were risk factors for postoperative liver metastasis of colon cancer. ROC curve analysis showed that the area under the curve of HALP score for predicting liver metastasis after colon cancer surgery was 0.908 (0.841, 0.974), the maximum value of the Youden index was 0.738, the optimal cut-off value of the HALP score was 35.5, the sensitivity was 0.852, the specificity was 0.886. Kaplan-Meier risk curve showed that the risk of early postoperative liver metastasis in the low HALP score group was higher than that in the high HALP score group (χ2=8.126, P=0.004). Conclusion Low HALP score in patients with colon cancer is associated with adverse prognosisi related pathological features, and is an influential factor for postoperative liver metastasis of colon cancer, and has predictive value for patients with postoperative liver metastasis of colon cancer.
