Quantitative magnetic susceptibility imaging sequence for intracranial inflammation in patients with optic neuromyelitis / 中国医师进修杂志

Objective:To identify the potential intracranial inflammation in neuromyelitis optica spectrum disorders(NMOSD) patients without supratentorial MRI lesions using quantitative susceptibility mapping (QSM).Methods:Seventy NMOSD patients and 35 age- and gender-matched healthy controls (NC) underwent QSM, 3D-T 1, diffusion MRI from Beijing Tiantan Hospital during June 2019 to June 2021. Susceptibility was compared among NMOSD patients with acute attack (ANMOSD), NMOSD patients in chronic phase (CNMOSD) and NC. The correlation between susceptibility in several brain regions and the cerebrospinal fluid levels of inflammatory makers were analyzed. Results:NMOSD patients showed different susceptibility in several brain regions including bilateral hippocampus, precuneus, right cuneus, putamen, superior parietal and inferior temporal ( P<0.001) and the posr-hoc showed it is higher than normal. Compared to CNMOSD patients, the ANMOSD patients showed increased susceptibility in the cuneus (0.009 ± 0.004 vs. 0.005 ± 0.004, P<0.05). There was significant positive correlations between susceptibility and CSF levels of sTREM2 which reflect the active of microglial cells ( r = 0.494, P<0.05). Conclusions:Despite the absence of supratentorial lesions on MRI, increased susceptibility suggests underlying inflammation in the cerebral cortex in both patients with ANMOSD and CNMOSD, and some of them are obviously related to inflammatory markers in CSF. QSM sequence can be used to explore the potential inflammation in NMOSD patients without obvious supratentorial lesions.

Short-term and long-term outcomes of uniportal versus three portal thoracoscopic radical resection of non-small cell lung cancer: A retrospective cohort study / 中国胸心血管外科临床杂志

@#Objective     To compare the short-term efficacy and long-term survival of patients with non-small cell lung cancer (NSCLC) treated by uniportal or three portal thoracoscopic radical resection. Methods     A total of 388 patients who underwent uniportal or three portal thoracoscopic radical resection of lung cancer in the Department of Thoracic Surgery of Anhui Chest Hospital from 2015 to 2016 were analyzed retrospectively. The patients were divided into two groups including an uniportal group and a three portal group according to the procedure. The clinicopathological features, perioperative data and long-term survival of the two groups were compared. Results     Finally, we included 205 patients with 105 males and 100 females at an average age of 58.73±10.93 years. There were 102 patients in the uniportal group and 103 patients in the three portal group. There was no statistical difference in clinicopathological features between the two groups (P>0.05). But compared with the three portal group, the uniportal group had less postoperative drainage, shorter postoperative catheterization time and postoperative hospital stay (P<0.05). There was no statistical difference in the number of lymph node dissection stations between the two groups (P=0.058). The pain score at 24 hours after operation in the uniportal group was significantly lower than that in the three portal group (P<0.001). There was no  statistical difference in the total incidence of complications and the incidence of pulmonary complications between the two groups (P=0.161 and P=0.275). The median survival period and the 1st, 3rd, and 5th year survival rate in the uniportal group was 63.0 months and 95.0%, 75.2%, 51.5%, respectively. The median survival period and the 1st, 3rd, and 5th year survival rate in the three portal group was 61.0 months and 89.3%, 70.9%, 50.5%, respectively. There was no satistical difference in the survival results between the two groups (P=0.440). Conclusion     Uniportal thoracoscopic radical resection of lung cancer is more minimally invasive and safe and effective in the treatment of NSCLC. It can make patients recover faster after operation.

Update and interpretation of Elsevier clinical pathway for gastric, gastroesophageal junction and esophageal cancer ( Chinese edition, 2022) / 中华消化杂志

The standardized treatment of malignant tumor has always been the direction of continuous improvement of major medical institutions. In recent years, the basic research, prevention, screening and diagnosis and treatment level of gastric, gastroesophageal junction and esophageal cancer have been greatly improved, resulting in a significant improvement in the 5 years′ survival rate of patients, but there are still great differences in the diagnosis and treatment level among different regions. Chinese gastric cancer, gastroesophageal junction cancer and esophageal cancer differ greatly from European and American countries in etiology, pathological types, high incidence sites, etc. Therefore, the relevant guidelines of European and American countries cannot fully meet Chinese clinical practice. In 2021, Elsevier Publishing Group launched the Chinese edition of Elsevier clinical pathway for gastric, gastroesophageal junction and esophageal cancer, and the first update edition was made in 2022, which aims to promote the quality control of tumor diagnosis and treatment, standardize tumor diagnosis and treatment behaviors, promote the homogenization and standardization of tumor diagnosis and treatment, and ultimately improve the survival rate and quality of life of patients with malignant tumor. This pathway refers to the National Comprehensive Cancer Network clinical practice guidelines, the Chinese Society of Clinical Oncology guidelines, combines evidence-based medicine and clinical experience, and follows the scientific, universal, standardized and operable principles. It has been promoted and applied in clinical practice, and is constantly updated according to the latest research results.

Chinese expert guidance on overall application of lenvatinib in hepatocellular carcinoma / 中华消化外科杂志

Lenvatinib mesylate is an oral receptor tyrosine kinase inhibitor against targets of vascular endothelial growth factor receptors 1-3, fibroblast growth factor receptors 1-4, platelet-derived growth factor receptor α, stem cell growth factor receptor, and rearranged during transfection, et al. Lenvatinib has been approved by the National Medical Products Administration of China on September 4,2018, for the first-line treatment of patients with unresectable hepatocellular carcinoma who have not received systematic treatment before. Up to February 2023, Lenvatinib has been listed in China for more than 4 years, accumulating a series of post-marketing clinical research evidences. Based on the clinical practice before and after the launch of lenvatinib and referring to the clinical experience of other anti-angiogenesis inhibitors, domestic multidisciplinary experts and scholars adopt the Delphi method to formulate the Chinese Expert Guidance on Overall Application of Lenvatinib in Hepatocellular Carcinoma after repeated discussions and revisions, in order to provide reference for reasonable and effective clinical application of lenvatinib for clinicians.

Acute kidney injury and acute lung injury/acute respiratory distress syndrome are common in the pediatric intensive care unit.Lung-kidney interaction in critically ill patients is closely related to anoxia, fluid management, and inflammatory response in acute kidney injury and acute lung injury/acute respiratory distress syndrome patients.Strengthening the understanding of lung-kidney interaction can help clinicians to systematically manage critically ill patients.

Influence of augmented renal clearance on the clinical application and therapeutic effect of vancomycin in critical children / 中国小儿急救医学

Objective:To explore the effect of augmented renal clearance(ARC)on 24-hour area under the concentration-time curve to minimum inhibitory concentration ratio(AUC 24/MIC)of vancomycin and prognosis in critical children, thus to provide proposal for individual dosage regimen. Methods:Sixty-five critical children treated with vancomycin, who suffered from sepsis/septic shock, were brought into this retrospective cohort study.According to estimate glomerular filtration rate, these children were divided into ARC group ( n=27) and normal group ( n=38). The influencing factor of AUC 24/MIC of vancomycin and therapy prognosis for two groups were detected and analyzed. Results:There were no significant differences between two groups in basic setting (age, sex, weight), scores of pediatric sequential organ failure assessment and pediatric risk of mortality Ⅲ, infection markers (C-reactive protein and procalcitonin), glutamic-pyruvic transaminase, hypoproteinemia, usage of diuretic and vasoactive agent( P>0.05). The patients from ARC group showed lower levels than those from normal group in AUC 24/MIC of vancomycin[375.2(300.8, 489.4) vs. 443.6(412.3, 593.2), Z=2.263, P=0.024] and it′s target achievement ratio (TAR)(40.7% vs. 76.3%, χ2=8.440, P=0.005). When usage of diuretic and vasoactive agent, the AUC 24/MIC of ARC group was lower than that of normal group( P<0.05). But there was no significant difference between ARC group and normal group regarding hypoproteinemia( P>0.05). The days of body temperature steady at least 48 hours[7.0(5.5, 9.0)d vs. 6.0(5.0, 8.0)d], the length of hospital stay[39.0(21.0, 58.0)d vs. 20.5(16.0, 28.0)d], the length of PICU stay[14.0(9.0, 31.5)d vs. 10.0(5.0, 15.0)d] were longer than those in normal group( P<0.05). There were no significant differences between ARC group and normal group regarding days of ventilation and infectious markers decreased at least 50%, as well as 28-days mortality( P>0.05). The multivariable analysis showed that the presence of ARC, hypoproteinemia, use of diuretics and vasoactive agent were significantly associated with AUC 24/MIC of vancomycin( P<0.05). Conclusion:ARC may down regulate levels of AUC 24/MIC and TAR of vancomycin.During ARC period, the usage of diuretic and vasoactive agent could affect the AUC 24/MIC of vancomycin.Individual dosage regimen should be employed for critical children suffered with ARC.

The use of portal vein embolization combined with lenvatinib and a PD-1 inhibitor to treat patients with initially unresectable hepatocellular carcinoma / 中华肝胆外科杂志

Objective:To study the safety and treatment outcomes of portal vein embolization (PVE) combined with lenvatinib plus an anti-programmed death-1(PD-1) antibody to treat patients with initially unreasectable hepatocellular carcinoma (uHCC).Methods:This study retrospectively analyzed the data of six patients with uHCC who received first-line combined systemic therapy with lenvatinib plus an anti-PD-1 antibody, and then underwent pre-hepatectomy PVE at the Department of Liver Surgery at Zhongshan Hospital, Fudan University from May 2019 to November 2020. All enrolled patients were males, aged (54.6±6.2) (ranged 46 to 63) years. Tumor response and liver volume were evaluated by medical imagings once every 2 months (±2 weeks) and evaluated using the Response Evaluation Criteria in Solid Tumours (version 1.1). Patients were followed-up by outpatient interviews or by phone calls to record their survival and tumor outcome status.Results:Three of the six enrolled patients had Barcelona Clinic Liver Cancer stage A and three had stage B disease. One patient achieved a partial response and five patients had stable diseases. The mean ± s. d. future liver remnant (FLR) percentage was (29.0±8.9) % before PVE and the combination therapy, and was (41.3±10.8) % before the last evaluation for liver surgery ( t=10.79, P<0.001). Hepatectomy was carried out in five patients, and one patient who failed to develop significant FLR hypertrophy did not undergo hepatectomy. Grade B post-hepatectomy liver failure and major postoperative complications (i.e. pleural effusion requiring additional percutaneous drainage) occurred in one patient. After a median post-operative follow-up of 4.5 (range: 1.0-12.3) months, all five patients were alive and were tumor free. Conclusion:PVE followed by hepatectomy is feasible in a uHCC patients receiving systemic therapy with lenvatinib and an anti-PD-1 antibody.

Meta-analysis of efficacy and safety of induction chemotherapy combined with radiotherapy±concurrent chemotherapy for nasopharyngeal carcinoma patients in the era of intensity-modulated radiation therapy / 中华放射肿瘤学杂志

Objective:To compare the efficacy and adverse events of induction chemotherapy combined with radiotherapy alone (IC+ RT) and induction chemotherapy combined with concurrent chemoradiotherapy (IC+ CCRT) for nasopharyngeal carcinoma in the era of intensity-modulated radiation therapy in this Meta-analysis.Methods:Retrospective or randomized controlled clinical studies published between 2010 and 2020 were searched from the Cochrane Library, PubMed, and Web of Science databases. The selected studies included nasopharyngeal carcinoma patients treated with IC+ CCRT or IC+ RT. STATA 12 software was used to combine the hazard ratio (HR), risk ratio (RR) and 95% confidence interval (CI), and random or fixed effect models were used for statistical analysis.Results:A total of 2483 patients from eight retrospective studies were included. The overall survival in the IC+ CCRT group was similar to that in the IC+ RT group ( HR=0.78, 95% CI: 0.58-1.04, P=0.091). However, the distant metastasis-free survival ( HR=0.56, 95% CI: 0.42-0.74, P<0.001) and progression-free survival ( HR=0.65, 95% CI: 0.54-0.77, P<0.001) were improved in the IC+ CCRT group compared with those in the IC+ RT group. In terms of adverse reactions, the acute adverse reactions in the IC+ CCRT group were increased significantly compared with those in the IC+ RT group. Conclusions:In the treatment of nasopharyngeal carcinoma, the overall survival of two treatment modes is similar, but the distant metastasis-free survival and progression-free survival in the IC+ CCRT group are better than those in the IC+ RT group, whereas the incidence of adverse reactions is also increased. IC+ CCRT may be a recommended treatment for nasopharyngeal carcinoma patients, but more research is needed.

Objective:To analyze the early clinical features of children with coronavirus disease 2019 (COVID-19) in order to further improve the understanding of the disease.Methods:A total of 312 children with COVID-19 under 16 years old who were first diagnosed in the children′s fever clinic at Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine from March to May 2022 were retrospectively analyzed.The epidemiology, early clinical features and blood routine results of children were described, and the blood routine results among different age groups were compared.Results:The median age of 312 children was 3.15(1.47, 6.51) years.The proportion of infection rate of children with different ages from high to low were 1~3 years old, > 6 years old, 3~6 years old and ≤ 1 year old.Only 17 (5.4%) cases had underlying diseases.Additionally, 70.2% patients had definite positive case reports in their residential communities, and 65.1% showed a familial cluster.Moreover, 96.2% patients had fever and 52.9% patients had respiratory symptoms.The main symptoms are fever (96.2%), cough (38.1%), runny nose (20.2%), vomiting (14.7%), sore throat (11.5%), poor appetite (6.7%), nasal congestion (4.5%), expectoration (4.5%), convulsion (4.2%), diarrhea (3.8%), etc.Among 309 children, 11.3% patients had increased white blood cell count, especially in children over 6 years old ( P=0.006); 31.7% patients had decreased lymphocyte count and 32.4% had increased C-reactive protein.The positive rate of point-of-care testing was as high as 99%. Conclusion:Children with COVID-19 in Shanghai had the characteristics of familial cluster.The main symptoms are fever and respiratory symptoms.Most of the blood routine leukocytes have no obvious changes, and a few have lymphopenia and C-reactive protein elevation.Point-of-care testing detection can help the children′s fever clinic to early screen COVID-19.

The predictive value of dynamic monitoring pediatric sequential organ failure assessment score for the prognosis in children with sepsis / 中国小儿急救医学

Objective:To dynamically monitor the pediatric sequential organ failure assessment(pSOFA) score of children in PICU at different time points, and to evaluate the predictive value of pSOFA score for the prognosis of children with sepsis.Methods:A multicenter prospective observational study was conducted to collect the data of children with sepsis admitted to the PICU of four children′s hospitals in Shanghai from December 2018 to December 2019(Children′s Hospital of Fudan University, Shanghai Children′s Medical Center Affiliated to Shanghai Jiaotong University School of Medicine, Shanghai Children′s Hospital Affiliated to Shanghai Jiaotong University School of Medicine, and Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine). We collected their pSOFA scores on the 1st, 3rd, and 7th day after sepsis diagnosis and the highest score.The patients were divided into survival group and death group according to the clinical outcomes at the time of leaving PICU.The clinical characteristics of two groups were compared.Receiver operating characteristic(ROC) curve were used to assess the resolution of the pSOFA score.Logistic regression was used to analyze the relationship between pSOFA score and sepsis mortality.Results:A total of 170 cases diagnosed sepsis were included, with a median age of 32.5(11.5, 83.2) months, and a median length of stay in PICU of 10(6, 21) days.Forty-two died and 128 survived.The medians of the 1st, 3rd, 7th day and the highest pSOFA score of the children in death group[10(7, 12) points, 9(5, 10) points, 7(4, 10) points, 11(7, 12) points, respectively] were higher than those in survival group[4(2, 8) points, 3(1, 6) points, 2(0, 5) points, 6(3, 8) points, respectively]( P<0.05). The area under the ROC curve of the pSOFA score predicting death on day 1 after sepsis diagnosis was greater than that on days 3, 7 and the highest pSOFA score[0.84(95% CI 0.79-0.91) vs.0.80(95% CI 0.71-0.89), 0.77(95% CI 0.65-0.89), 0.83(95% CI 0.77-0.90)], but the difference was not statistically significant( χ2=1.660, P=0.646). The pSOFA score on the first day of diagnosis had the best cut-off value of >6 points for predicting the risk of death from sepsis, with a sensitivity of 97.6% and a specificity of 53.9%.Logistic regression analysis of pSOFA score and childhood sepsis death showed that the OR values corresponding to the 1st, 3rd, 7th day of diagnosis and the highest pSOFA score were 1.58(95% CI 1.350-1.840), 1.39(95% CI 1.218-1.595), 1.38(95% CI 1.184-1.617) and 1.55(95% CI 1.333-1.800), respectively(all P<0.05). The 1-point increase in pSOFA score on the first day of diagnosis of sepsis was associated with a 58% increase in the hazard ratio for death, and each 1-point increase in the highest pSOFA score was associated with a 55% increase in the hazard ratio for death. Conclusion:The 1st, 3rd, 7th day of sepsis diagnosis and the highest pSOFA score could better predict the mortality risk of sepsis in children.Dynamic monitoring of the pSOFA score at different time points has a certain clinical value in predicting the progression and prognosis of children with sepsis.

A novel model in predicting very early recurrence after surgical resection of hepatocellular carcinoma / 中华肝胆外科杂志

Objective:To study the risk factors of very early recurrence (VER, within 3 months) after R 0 resection of hepatocellular carcinoma (HCC), and to establish a predictive model. Methods:Of 427 HCC patients [with 368 males, 59 females, aged (52.7±12.1) years] who developed early recurrence (within 2 years) after R 0 resection from January to December 2008 at Zhongshan Hospital, Fudan University were enrolled in the test cohort. Another 590 patients [with 525 males, 65 females, aged (54.7±11.0) years] who underwent R 0 resection from January to June 2009 were enrolled in the validation cohort. Risk factors were investigated and a predictive model was established. Results:In the test cohort, 126 patients (29.5%) developed VER and their survival outcomes were extremely poor. Serum α-fetoprotein (AFP) level >827 μg/L, multiple tumors, microvascular invasion (MVI) and tumor number were independent risk factors for VER. A new predictive model (0.809·AFP+ 1.262·tumor number+ 0.983·MVI) was established by logistic regression in predicting VER after surgery. The receiver operating characteristic curve showed that the area under the curve (AUC) in predicting VER was 0.722 (95% CI: 0.669-0.774, P<0.001). In the validation cohort, the AUC of this model was 0.785 (95% CI: 0.715-0.855, P<0.001). Conclusions:A high AFP level, multiple tumors, and MVI were independent risk factors for VER of HCC after R 0 resection. The prediction model consisting of these three factors demonstrated robustness and it has the potential in clinical application.

Sepsis-related mortality and family socioeconomic features of septic patients in pediatric intensive care unit in the Yangtze River Delta / 中国小儿急救医学

Objective:To investigate pediatric sepsis-related mortality of pediatric intensive care unit(PICU) and family socioeconomic status in Yangtze River Delta.Methods:A prospective, multicenter observational study was conducted to collect sepsis cases from eight PICUs in Jiangsu, Zhejiang and Shanghai from August 2016 to July 2017.Sepsis cases were divided into normal sepsis group and severe sepsis group.The primary outcome was in-hospital death.Patient data were prospectively collected including age, gender, medical insurance status, long-term residence, source of admission, first-day pediatric sequential organ failure score(pSOFA) score, underlying diseases and socioeconomic characteristics including family education level, family annual economic income.Results:A total of 4, 983 patients admitted in PICUs, of which 651 patients were diagnosed sepsis on admission.The prevalence of sepsis was 13.1% (651/4 983), and overall mortality was 11.7% (76/651). The prevalence of severe sepsis was 28.3% (184/651), and the mortality was 20.1% (37/184). The overall median age was 0.9 years old.The infant group accounted for 50.8%, including 331 cases, followed by toddler group 19.8% (129 cases), preschool group 13.0% (86 cases), school group 11.8% (77 cases), and adolescent group 4.3% (28 cases). The median pSOFA score was 4.Logistic regression analysis showed that the OR value was 1.4(95% CI 1.3-1.5) of pSOFA score corresponding to the death of sepsis in hospital.There were 14.6% patients left hospital in medical insurance group, while 27.4% in non-medical insurance group, and there was significant difference between these two groups.The median of daily cost was 5, 446 RMB, among which the median of daily cost of sever sepsis was 6, 678 RMB.The median of total cost for sepsis was 36, 109 RMB, and that for severe sepsis was 41, 433 RMB. Conclusion:The sepsis-related mortality was high in PICU.The pSOFA score has a certain predictive value for the prognosis of sepsis.The burden of sepsis is still heavy.Compared with medical insurance families, non-medical insurance families have a higher proportion of choosing left hospital.

Expression and significance of L1 cell adhesion molecule and transforming growth factor-β1 in pancreatic cancer tissue / 临床肝胆病杂志

ObjectiveTo investigate the expression of L1 cell adhesion molecule (L1CAM) and transforming growth factor-β1 (TGFβ1) in pancreatic cancer tissue and their association with the prognosis of pancreatic cancer. MethodsHistological specimens were collected from 125 patients with pancreatic cancer who underwent surgical resection in The First Affiliated Hospital of Guangxi Medical University, Guangxi Medical University Cancer Hospital, and Wuming Hospital of Guangxi Medical University from January 2015 to January 2018. Immunohistochemistry was used to measure the expression of L1CAM and TGFβ1 in all specimens, and the association of the expression of L1CAM and TGFβ1 with clinical indices, survival, and prognosis was analyzed. The t-test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups; the Cox proportional-hazards regression model was used to investigate the influencing factors for the survival of patients with pancreatic cancer; the Kaplan-Meier survival analysis was used to evaluate the survival of patients with different expression levels of L1CAM and TGFβ1. ResultsThe high protein expression rate of L1CAM in pancreatic cancer tissue was significantly higher than that in adjacent tissue (75.20% vs 20.00%, χ2=76.352, P＜0.001). The high protein expression rate of TGFβ1 in pancreatic cancer tissue was significantly higher than that in adjacent tissue (8160% vs 23.20%, χ2=85.461, P＜0.001). The protein expression of L1CAM was positively correlated with that of TGFβ1 in pancreatic cancer (r=0.492, P＜0.001). The protein expression of L1CAM and TGFβ1 were associated with tumor size, degree of tumor differentiation, TNM stage, lymph node metastasis, intravascular tumor thrombus, and perineural invasion (all P＜0.05). The patients with high protein expression of L1CAM or TGFβ1 had a significantly lower overall survival rate than those with low expression (χ2=54661 and 39597, both P＜0.001). ConclusionL1CAM and TGFβ1 proteins are highly expressed in pancreatic cancer tissue and may be associated with poor prognosis by promoting lymphatic metastasis and hematogenous metastasis. L1CAM and TGFβ1 proteins play an important role in the development, progression, and metastasis of pancreatic cancer.

Serum expression of angiopoietin-like protein 2 in pancreatic cancer patients with or without diabetes and its association with prognosis / 临床肝胆病杂志

ObjectiveTo investigate the expression level of angiopoietin-like protein 2 (ANGPTL2) in pancreatic cancer patients with or without diabetes and the clinical value of ANGPTL2 as a prognostic marker in patients with pancreatic cancer. MethodsSerum samples were collected from 125 pancreatic cancer patients who were treated in The First Affiliated Hospital of Guangxi Medical University, Guangxi Medical University Cancer Hospital, and Wuming Hospital of Guangxi Medical University from January 2015 to January 2018, among whom 64 had pancreatic cancer alone and 61 had pancreatic cancer and diabetes, and 66 individuals who underwent physical examination were enrolled as control group. ELISA was used to measure the serum level of ANGPTL2, and the association of the expression level of ANGPTL2 with clinical indices, survival, and prognosis was analyzed. A one-way analysis of variance was used for comparison of normally distributed continuous data between three groups, and the Bonferroni test was used for comparison between two groups. The independent-samples Kruskal-Wallis H test was used for comparison of continuous data with skewed distribution between three groups and the one-way ANOVA analysis was used for comparison between two groups. The chi-square test was used for comparison of categorical data between groups. Spearman correlation analysis was also performed to investigate correlation. The Kaplan-Meier method was used to plot survival curves, and the log-rank test was used for comparison of survival rate. The Cox risk model was used to perform univariate and multivariate analyses to determine independent risk factors for the prognosis of pancreatic cancer. ResultsThe pancreatic cancer+diabetes group had a significantly higher serum concentration of ANGPTL2 than the pancreatic cancer group and the control group ［7.79 (7.12-8.17) ng/ml vs 5.74 (508-6.40) ng/ml and 3.72 (3.25-4.16) ng/ml, χ2=126.367, P＜0.001］. Serum ANGPTL2 concentration was positively correlated with carbohydrate antigen 19-9 (CA19-9) and carcinoembryonic antigen (CEA) (r=0.560 and 0.731, both P＜0.001). The univariate analysis showed that tumor size, distant organ metastasis, degree of tumor differentiation， CEA, ANGPTL2, and HbA1c were closely associated with the long-term survival of pancreatic cancer patients, and the multivariate analysis showed that tumor size (HR=2.657,P=0.005), distant organ metastasis (HR=5.000,P=0.014), degree of tumor differentiation (HR=2.466,P=0.004), CEA(HR=1.110,P＜0.001) and ANGPTL2(HR=1.901,P=0.001) were independent risk factors for the prognosis of pancreatic cancer patients. For all pancreatic cancer patients, the high ANGPTL2 expression group had a significantly lower 2-year survival rate than the low ANGPTL2 expression group (8.51% vs 25.81%, χ2=5.651, P=0.017). For the pancreatic cancer patients with diabetes, the high ANGPTL2 expression group had a significantly lower 2-year survival rate than the low ANGPTL2 expression group (2.20% vs 32.70%, χ2=24.895, P＜0.001).ConclusionANGPTL2 can be used as an effective clinical index to evaluate the prognosis of pancreatic cancer patients, especially those with diabetes.
