Objective To compare and analyze the application value of domestic Octoparms and imported Celect inferior vena cava filter(IVCF)in the interventional treatment of venous thromboembolism(VTE).Methods Forty patients with VTE were randomly divided into Octoparms group(experimental group)and Celect group(control group)according to the double-blinded method of the central random system.All the patients underwent filter placement,catheter-directed thrombolysis and filter retrieval.The primary end point was the success of filter placement and retrieval,and the secondary end point included indwelling complications such as the occurrence of pulmonary embolism(PE)and filter tilt and migration.Results Forty patients were enrolled in this study,22 patients and 18 patients were divided into the experimental group and the control group,respectively.Among them,11 cases were identified with right lower extremity deep vein thrombosis,29 cases with left lower extremity deep vein thrombosis,17 cases with PE,and 6 cases with inferior vena cava thrombosis.The success rate of IVCF placement was 100%in all participants.Immediately after filter place-ment,the angle of filter tilt was(3.8±2.3)° in the experimental group and(4.9±2.8)° in the control group(t=1.44,P=0.16).Filter retrieval was successful in 21 cases(21/22,95.5%)of the experimental group and 17 cases(17/18,95.5%)of the control group.There was no significant difference between the two groups(t=0.14,P=0.89).The mean indwelling time of filter was(8.0±2.1)days in the experimental group and(9.7±3.1)days in the control group(t=0.73,P=0.47).The angle of filter tilt was(5.3±3.4)° in the experimental group and(5.7±7.7)° in the control group(t=0.19,P=0.85).There was no significant difference for filter placement and retrieval between the two groups(t=0.48 and 2.00,P=0.06 and 0.64,respectively).There were no complications of filter migration,strut penetration or new PE in both groups.Conclusion The application value of domestic Octoparms and impor-ted Celect IVCF is similar in interventional treatment of VTE.

Objective:To study the risk factors of Budd-Chiari syndrome (BCS) associated with hepatocellular carcinoma in patients who underwent endovascular recanalization.Methods:The data of 340 patients with BCS who underwent endovascular recanalization at the Affiliated Hospital of Xuzhou Medical University between January 2015 and June 2021 were retrospectively collected. Using propensity score matching, a total of 57 patients (40 males and 17 females) were enrolled into this study, with the age of (50.4±8.7) years. Patients were divided into the hepatocellular carcinoma group ( n=19) and the control group ( n=38) according to whether occurrence of hepatocellular carcinoma after cardovascular recanalization. Preoperative indicators including gender, age, BCS type, and model for end-stage liver disease (MELD) score, and postoperative indicators including alpha fetoprotein, intrahepatic nodule formation, vascular restenosis, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were compared between the two groups after propensity score matching. Multivariate logistic regression analysis was used to analyze the risk factors of BCS associated with after endovascular recanalization in these patients. Results:There were no significant differences in gender, age, BCS type, MELD score and other preoperative data between the two groups (all P>0.05). The proportions of patients with postoperative alpha fetoprotein>9.0 μg/L, AST>40 U/L, ALT>50 U/L, intrahepatic nodules and vascular restenosis after endovascular treatment in the hepatocellular carcinoma group were significantly higher than those in the control group (all P<0.05). Multivariate analysis showed postoperative alpha fetoprotein >9.0 μg/L ( OR=46.778, 95% CI: 3.310-661.140), AST>40 U/L ( OR=36.307, 95% CI: 1.317-1 001.009), intrahepatic nodule formation ( OR=66.254, 95% CI: 4.225-1 038.974) and vascular restenosis ( OR=16.276, 95% CI: 1.712-154.773) to have an increased risk of being associated with hepatocellular carcinoma in these BCS patients (all P<0.05). Conclusion:Postoperative alpha fetoprotein>9.0 μg/L, AST>40 U/L, intrahepatic nodule formation and vascular restenosis were independent risk factors of BCS associated with hepatocellular carcinoma in patients who underwent endovascular recanalization.

Objective:To characterize the histopathological subtypes and their clinicopathological parameters of gender and onset age by common, rare and sparse primary esophageal malignant tumors (PEMT).Methods:A total of 272 437 patients with PEMT were enrolled in this study, and all of the patients were received radical surgery. The clinicopathological information of the patients was obtained from the database established by the State Key Laboratory of Esophageal Cancer Prevention & Treatment from September 1973 to December 2020, which included the clinical treatment, pathological diagnosis and follow-up information of esophagus and gastric cardia cancers. All patients were diagnosed and classified by the criteria of esophageal tumor histopathological diagnosis and classification (2019) of the World Health Organization (WHO). The esophageal tumors, which were not included in the WHO classification, were analyzed separately according to the postoperative pathological diagnosis. The χ 2 test was performed by the SPSS 25.0 software on count data, and the test standard α=0.05. Results:A total of 32 histopathological types were identified in the enrolled PEMT patients, of which 10 subtypes were not included in the WHO classification. According to the frequency, PEMT were divided into common (esophageal squamous cell carcinoma, ESCC, accounting for 97.1%), rare (esophageal adenocarcinoma, EAC, accounting for 2.3%) and sparse (mainly esophageal small cell carcinoma, malignant melanoma, etc., accounting for 0.6%). All the common, rare, and sparse types occurred predominantly in male patients, and the gender difference of rare type was most significant (EAC, male∶ female, 2.67∶1), followed with common type (ESCC, male∶ female, 1.78∶1) and sparse type (male∶ female, 1.71∶1). The common type (ESCC) mainly occurred in the middle thoracic segment (65.2%), while the rare type (EAC) mainly occurred in the lower thoracic segment (56.8%). Among the sparse type, malignant melanoma and malignant fibrous histiocytoma were both predominantly located in the lower thoracic segment (51.7%, 66.7%), and the others were mainly in the middle thoracic segment.Conclusion:ESCC is the most common type among the 32 histopathological types of PEMT, followed by EAC as the rare type, and esophageal small cell carcinoma and malignant melanoma as the major sparse type, and all of which are mainly occur in male patients. The common type of ESCC mainly occur in the middle thoracic segment, while the rare type of EAC mainly in the lower thoracic segment. The mainly sparse type of malignant melanoma and malignant fibrous histiocytoma predominately occur in the lower thoracic segment, and the remaining sparse types mainly occur in the middle thoracic segment.

Objective:To investigate the clinical features of JAK2V617F gene mutation and non-mutation in patients with Budd-Chiari syndrome (BCS).Methods:17 and 127 BCS cases with JAK2V617F gene mutation (mutation group) and non-gene mutation (non-mutation group) who were continuously treated with interventional therapy between January 2016 to December 2020 in the Affiliated Hospital of Xuzhou Medical University were selected as the research object for a comparative study. The hospitalization and follow-up data of the two groups were analyzed retrospectively, and the deadline for follow-up was June 2021. Quantitative data group differences were analyzed using the independent sample t-test and Wilcoxon rank sum test. Qualitative data group differences were analyzed with χ2 test or Fisher's exact test. Mann-Whitney U test was used to analyze the differences between groups in rank data. Kaplan-Meier method was used to calculate the patient survival and recurrence rate. Results:Age [(35.41±17.10) years vs. (50.09±14.16) years, t=3.915, P<0.001], time of onset (median duration: 3 months vs. 12 months), and the cumulative survival rate (65.5% vs 95.1%; χ2=5.21, P=0.022) were lower in mutation than non-mutation group. Aaspartate aminotransferase, alanine aminotransferase, prothrombin time, Child-Pugh score, Rotterdam score, Model for End-stage Liver Disease score, hepatic vein thrombosis incidence, and the cumulative recurrence rate after intervention were higher in mutation than non-mutation group. The above all indexes had statistically significant differences ( P<0.05) between the groups. Conclusion:Younger age, acute onset, severe liver injury, high incidence of hepatic vein thrombosis, and poor prognosis are the features of patients with BCS with JAK2V617F gene mutation than non-mutation.

Objective: The relationship between outdoor temperature and blood pressure (BP) has been inconclusive. We analyzed data from a prospective cohort study in northwestern China to investigate the effect of outdoor temperature on BP and effect modification by season. Methods: A total of 32,710 individuals who participated in both the baseline survey and the first follow-up in 2011-2015 were included in the study. A linear mixed-effect model and generalized additive mixed model (GAMM) were applied to estimate the association between outdoor temperature and BP after adjusting for confounding variables. Results: The mean differences in systolic blood pressure (SBP) and diastolic blood pressure (DBP) between summer and winter were 3.5 mmHg and 2.75 mmHg, respectively. After adjusting for individual characteristics, meteorological factors and air pollutants, a significant increase in SBP and DBP was observed for lag 06 day and lag 04 day, a 0.28 mmHg (95% Conclusions This study demonstrated a significant negative association between outdoor temperature and BP in a high-altitude environment of northwest China. Moreover, BP showed a significant seasonal variation. The association between BP and temperature differed by season and individuals' demographic characteristics (age, gender, BMI), unhealthy behaviors (smoking and alcohol consumption), and chronic disease status (CVDs, hypertension, and diabetes).

Objective:To study the use of three-dimensional (3D) visualization in diagnosis and interventional treatment of patients with Budd-Chiari syndrome (BCS) presenting with inferior vena cava obstruction and dangerous collateral branches.Methods:The data of 28 patients with BCS presenting with inferior vena cava obstruction and dangerous collateral branches treated at the Affiliated Hospital of Xuzhou Medical University from September 2018 to January 2021 were retrospectively analyzed. There were 11 males and 17 females with a mean age of 49.0 years. Enhanced MR images of these 28 patients were used to build 3D visualization of inferior vena cava. Anteroposterior and left lateral digital subtraction angiography (DSA) of inferior vena cava were performed. The inferior vena cava of these patients was recanalized under guidance of 3D visualization, and patency of inferior vena cava was determined on follow up.Results:3D visualization of inferior vena cava was successfully constructed in all the 28 patients, and 51 dangerous collateral branches were displayed. One, 2, 3 and 4 dangerous collateral branches were found in 13, 8, 6 and 1 patients, respectively. The average angle between the preoperative planning puncture route and the long axis of the proximal end of inferior vena cava was 22.2°. The orifices and courses of the dangerous collaterals and the shape of inferior vena cava could be clearly displayed on 3D visualization in all the 28 patients (100.0%), which were significantly better than the 6 patients (21.4%) using DSA obtained in the anteroposterior and left lateral positions (χ 2=20.045, P<0.05). The inferior vena cava was successfully recanalized in all the 28 patients without complications. On follow up of these patients for 2 to 30 months (mean 18.4 months), the inferior vena cava was patent in 25 patients. Three patients developed inferior vena cava re-obstruction at 3, 4 and 14 months after interventional treatment, respectively. Conclusion:3D visualization was useful in the diagnosis and interventional treatment of patients with BCS presenting with inferior vena cava obstruction and dangerous collateral branches.

Objective:To investigate the efficacy of transjugular intrahepatic portosystemic shunt (TIPS) using viabahn stent in patients with Budd-Chiari syndrome (BCS) with extensive hepatic vein occlusion.Methods:Technical success rates, portal pressure gradient (PPG), complications and shunt patency rate of 25 cases with BCS with extensive hepatic vein occlusion treated by TIPS using viabahn stent were retrospectively analyzed. Color Doppler ultrasound was used for postoperative follow-up. Patency rates were evaluated by Kaplan-Meier curve.Results:The technical success rate of TIPS was 100%. Mean PPG decreased from (22.7 ± 6.2) mmHg preoperatively to (9.7 ± 2.6) mmHg postoperatively ( t = 9.58, P < 0.05). Hepatic encephalopathy incidence was 8.0% (2/25), and there were no complications such as intra-abdominal hemorrhage. Twenty-five cases were followed up for 1 to 39 ( mean 19.0 ± 11.9) months, and one patient died of liver failure three months after interventional treatment. The primary patency rates at 1, 2, and 3 years after interventional treatment were 91.3%, 91.3%, and 78.2%, respectively, while the repatency rates were 100%, 92.9%, and 92.9%, respectively. Conclusion:TIPS using viabahn stent can bring better short-term and mid-term curative efficacy in treatment of BCS with extensive hepatic vein occlusion.

Objective:To understand the occurrence of intraoperative memory (dream, halluci- nation, and intraoperative awareness) following anesthesia with propofol and sufentanil and analyze its influen- cing factors in patients undergoing painless curettage of the uterine cavity.Methods:The modified Brice questionnaire survey results in patients who underwent painless curettage of the uterine cavity under propofol and sufentanil anesthesia in Shuangqiao Hospital from January 2017 to September 2018 were retrospectively analyzed. The memory of patients from anesthesia induction to consciousness recovery after anesthesia was evaluated, and the incidences of dream, hallucination (including sexual hallucination), and intraoperative awareness were calculated. The possible influencing factors (including age, weight, operation time, initial and total dose of propofol, and total dose of sufentanil) of intraoperative memory after anesthesia with propofol and sufentanil were analyzed using logistic regression method.Results:A total of 2 142 patients were enrolled, aged (28.3±7.4) years and weighing (61.8±10.2) kg, with gestational age of (7.8±1.3) weeks and a median operation time of 5 (3-28) min; the initial dose of propofol was (94.1±20.9) mg, with a total dose of (110.0±39.8) mg; the total dose of sufentanil was (9.9±0.4) μg. Among the 2 142 patients, 1 038 (48.5%) had memory from anesthesia induction to consciousness recovery after anesthesia, 1 019 (98.2%) of which were defined as dreams, 19 (1.8%) as hallucinations, and no one had intraoperative awareness. Eleven of 1 038 patients were defined as having sexual hallucinations and the incidence was 0.5%. There was no significant correlation between the occurrence of intraoperative memory and age, weight, operation time, initial dose and total dose of propofol, and total dose of sufentanil ( P>0.05 for all). Conclusion:The anesthesia of propofol combined with sufentanil may lead to dreams and hallucinations in patients undergoing painless curettage of the uterine cavity, and occurrence of sexual hallucinations should be more paid attention to.
