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 evaluate the efficacy and safety of hybutimibe monotherapy or in combination with atorvastatin in the treatment of primary hypercholesterolemia. Methods: This was a multicenter, randomized, double-blind, double-dummy, parallel-controlled phase Ⅲ clinical trial of patients with untreated primary hypercholesterolemia from 41 centers in China between August 2015 and April 2019. Patients were randomly assigned, at a ratio of 1∶1∶1∶1∶1∶1, to the atorvastatin 10 mg group (group A), hybutimibe 20 mg group (group B), hybutimibe 20 mg plus atorvastatin 10 mg group (group C), hybutimibe 10 mg group (group D), hybutimibe 10 mg plus atorvastatin 10 mg group (group E), and placebo group (group F). After a dietary run-in period for at least 4 weeks, all patients were administered orally once a day according to their groups. The treatment period was 12 weeks after the first dose of the study drug, and efficacy and safety were evaluated at weeks 2, 4, 8, and 12. After the treatment period, patients voluntarily entered the long-term safety evaluation period and continued the assigned treatment (those in group F were randomly assigned to group B or D), with 40 weeks' observation. The primary endpoint was the percent change in low density lipoprotein cholesterol (LDL-C) from baseline at week 12. Secondary endpoints included the percent changes in high density lipoprotein cholesterol (HDL-C), triglyceride (TG), apolipoprotein B (Apo B) at week 12 and changes of the four above-mentioned lipid indicators at weeks 18, 24, 38, and 52. Safety was evaluated during the whole treatment period. Results: Totally, 727 patients were included in the treatment period with a mean age of (55.0±9.3) years old, including 253 males. No statistical differences were observed among the groups in demographics, comorbidities, and baseline blood lipid levels. At week 12, the percent changes in LDL-C were significantly different among groups A to F (all P<0.01). Compared to atorvastatin alone, hybutimibe combined with atorvastatin could further improve LDL-C, TG, and Apo B (all P<0.05). Furthermore, there was no significant difference in percent changes in LDL-C at week 12 between group C and group E (P=0.991 7). During the long-term evaluation period, there were intergroup statistical differences in changes of LDL-C, TG and Apo B at 18, 24, 38, and 52 weeks from baseline among the statins group (group A), hybutimibe group (groups B, D, and F), and combination group (groups C and E) (all P<0.01), with the best effect observed in the combination group. The incidence of adverse events was 64.2% in the statins group, 61.7% in the hybutimibe group, and 71.0% in the combination group during the long-term evaluation period. No treatment-related serious adverse events or adverse events leading to death occurred during the 52-week study period. Conclusions: Hybutimibe combined with atorvastatin showed confirmatory efficacy in patients with untreated primary hypercholesterolemia, which could further enhance the efficacy on the basis of atorvastatin monotherapy, with a good overall safety profile.

Objective:To investigate the changes of liver volume and liver function in patients with extensive hepatic vein occluded Budd-Chiari syndrome (BCS) treated with transjugular intrahepatic portosystem shunt (TIPS).Methods:The clinical data of 29 BCS patients from Affiliated Hospital of Xuzhou Medical University during March 2016 to June 2019 were retrospectively collected and analyzed. The BCS was caused by extensive hepatic vein occlusion and patients were treated with TIPS. Pre- and postoperative abdominal CT/MRI images were collected and analyzed, and hepatic volume was measured with 3D-reconstruction. The liver volume and liver function during before and post the surgery were also collected and analyzed with preoperative value.Results:Patients including 8 males and 21 females, aged (33.3±6.3) years, were enrolled in this study. TIPS was successfully performed in all patients, with a technical success rate 100%. No serious complications related to TIPS occurred. Patients were followed up for 12-33 months (median, 16 months). Compared with preoperative [(2 124.6±420.9) cm 3] , the hepatic volume of time points after operation [1 week: (1 926.3±372.3) cm 3; 3 months: (1 480.6±183.1) cm 3; 6 months: (1 461.9±153.0) cm 3; 12 months: (1 469.3±148.5) cm 3] were all significantly reduced, and the differences were statistically significant ( P<0.05). Compared with preoperative values, the hepatic function indexes at each time point after operation were significantly improved ( P<0.05). The complete remission rate of ascites was 96.4% (27/28), 100.0% (28/28) and 100.0% (28/28) at 3, 6 and 12 months, respectively. Conclusion:The extensive hepatic vein occlusive BCS patients were benefit from TIPS therapy. Six months after operation, the hepatic volume and the hepatic function returned to normal level.

OBJECTIVE: To investigate the age distribution characteristics of intestinal segmented filamentous bacteria (SFB) in children and their relationship with intestinal mucosal immunity. METHODS: The fresh feces of 177 children and the ileocecal fluid of 47 children during colonoscopy were collected. The SFB was determined by real-time PCR. The concentration of secretory immunoglobulin A (sIgA) was determined by enzyme-linked immunosorbent assay. The numbers of interleukin 17A (IL-17A) cells and intraepithelial lymphocytes in the terminal ileum mucosa and the expression of transcription factors associated with the differentiation of T helper (Th) cells, T-box transcription factor (T-bet), forkhead box P3 (FOXP3), and retinoid-related orphan receptor gamma t (ROR-γt), were determined by immunohistochemistry. RESULTS: The positive rate of intestinal SFB in these children was 19.2% (34/177). Trend analysis showed that the positive rate of SFB was correlated with age: the rates for children aged 0-, 1-, 2-, 3-, 4-, 5-, 6-, and 7-15 years were 40%, 47%, 32%, 15%, 12%, 13%, 15% and 4% respectively (P<0.001). The concentration of sIgA in intestinal fluid was significantly higher in SFB-positive children (n=24) than in SFB-negative children (n=23) (P<0.01). The number of intraepithelial lymphocytes in the terminal ileum mucosa and the expression of T-bet, FOXP3, and ROR-γt were not significantly different between the SFB-positive group (n=12) and the SFB-negative group (n=11), but the number of IL-17A cells in the terminal ileum mucosa was significantly lower in the SFB-positive group than in the SFB-negative group (P<0.05). CONCLUSIONS Intestinal SFB colonization in children is age-related, and the colonization rate is relatively high in children under 3 years old. In SFB-positive children, the secretion of intestinal sIgA is increased, while the number of IL-17A cells in the terminal ileum is reduced.

Objective To evaluate the clinical effect of reduced glutathione in protecting the liver function for patients with hepatocellular carcinoma (HCC) after receiving international therapy.Methods The clinical data of 110 HCC patients,who were admitted to authors' hospital during the period from January 2010 to June 2013,were retrospectively analyzed.According to the random number table method the patients were divided into the control group (n=50) and the treatment group (n=60),and transcatheter arterial chemoembolzation (TACE) and transcatheter arterial infusion (TAI) were carried out in all patients.After the treatment,intravenous infusion of 2.0 g vitamin C,0.2 g vitamin B6,2.0 g inosine,and 250 ml branched chain amino acid was employed per day for one week for the patients of both groups,and additional intravenous dripping of 1.8 g reduced glutathione (added in 250 ml of 5％ glucose solution) was adopted for the patients of the treatment group.Various liver function indexes were tested before and one week after the treatment,the results were compared between the two groups.Results Before the treatment,no obvious differences in the hepatic functions and in the clinical condition existed between the two groups.One week after the treatment,in both groups the aminotransferase (ALT and AST) and total bilirubin (TBIL) were significantly increased when compared with the preoperative data (P＜0.05),while the serum pre-albumin (PA) was remarkably decreased when compared with the preoperative data (P＜0.05);these changes of various indexes in the treatment group were apparently better than those in the control group (P＜0.05).Conclusion The use of reduced glutathione can effectively relieve the liver function damage caused by interventional therapy in HCC patients,therefore,reduced glutathione has a very good clinical application value.

Objective To explore the endovascular treatment of Budd-Chiari syndrome (BCS) in young child. Methods The clinical data of one young child diagnosed with BCS and treated with endovascular therapy were retrospectively analyzed. Results The 23-month-old female suffered from repeated abdominal distension for 3 months and was diagnosed with BCS by vascular ultrasound Doppler and magnetic resonance examination. After confirmation of the diagnosis, endovascular treatment was performed. Then the occluded blood vessels resumed blood stream, urine output increased, and abdominal distension was significant relieved. Conclusions In young children, BCS is rare, the condition is complex, and endovascular therapy is effective.

Objective To explore the effect of sequential therapy of transcatheter arterial chemoembolization (TACE) followed by percutaneous microwave coagulation therapy (PMCT) in treating early-stage primary hepatocellular carcinoma (PHC), and to analyze the factors that may affect the prognosis. Methods During the period from Jan. 2011 to Apr. 2014, a total of 66 patients with early-stage PHC were admitted to authors’ hospital. TACE was carried out in all patients, which was followed by PMCT in 5 -7 days. All patients were followed up regularly. CT, MR, ultrasonography, AFP, liver function and other related laboratory tests were performed. Kaplan-Meier estimation was used for the analysis of disease-free survival time. The high-risk factors were analyzed by Chi-square test. Multivariate analysis was conducted by using logistic analysis method. Results After TACE the serum levels of ALT, TBIL and DBIL were increased significantly when compared with preoperative ones (P< 0.01). After sequential PMCT the serum levels of AST, ALT and DBIL were increased significantly when compared with preoperative ones (P< 0.01). When compared with TACE, after sequential PMCT the serum level of AST was increased (P< 0.01), while serum levels of TBIL and DBIL were decreased (P< 0.01). Compared with TACE and preoperative data, the post-PMCT AFP level was decreased (P < 0.01). During the follow-up period one patient died. The 3-year cumulative survival rate was 98.5%. Recurrence was seen in 19 cases. The one-year, 2-year and 3-year disease-free cumulative survival rate was 70.3%, 50.8% and 41.6% respectively. Univariate and multivariate analysis indicated that the risk factors of recurrence in early-stage PHC included AFP ≥ 100 μg/L, viral load≥103 copies/ml and irregularity of tumor border (P<0.05). Conclusion Sequential therapy of TACE followed by PMCT is an ideal treatment for early-stage PHC, sequential PMCT after TACE does not affect liver recovery process. AFP ≥ 100 μg/L, viral load ≥ 103 copies/ml and irregularity of tumor border are the risk factors of recurrence.

Objective To evaluate the safety and efficacy of interventional treatment of occlusion of the entire inferior vena cava (IVC).Methods The clinical data of 6 patients with entire IVC occlusion were analyzed retrospectively.All patients were diagnosed by color Doppler ultrasound and DSA.Venography was performed under local anesthesia via internal jugular vein and femoral vein approach.The occlusion of IVC and hepatic vein were treated with balloon dilatation and/or stent placement.Follow-up examination with color Doppler ultrasound was taken 1,3,6,12 months after treatment and annually thereafter to assess the patency of IVC and hepatic vein.The pressure gradient of hepatic vein-right atrium and IVC-right atrium before and after interventional treatment were compared with paired t test.Results In 5 cases,both IVC and 1 hepatic vein were recanalized successfully.In 1 case,recanalization of IVC failed,but the right hepatic vein was recanalized successfully.The mean pressure gradient of hepatic vein-right atrium decreased from (23.2 ± 2.0) cmH2O (1 cmH2O =0.098 kPa) before treatment to (8.7 ± 3.2) cmH2O after treatment in 6 cases (t =21.6,P ＜ 0.05).The mean pressure gradient of IVC-right atrium decreased from (26.6 ± 2.7) cmH2O before treatment to (9.4 ± 1.1) cmH2O after treatment (t =16.1,P ＜ 0.05).Abdominal pains occurred in 3 patients after stent implantation which disappeared in 24 hours.No other complications such as bleeding and death occurred.During a mean follow-up of(42 ± 27)months (16 to 90 months),hepatic vein patency was maintained in 6 cases and IVC patency was maintained in 5 cases.Conclusion Interventional treatment of occlusion of the entire IVC is a safe and effective method.
