Objective To investigate the imaging manifestations and pathological basis of hepatic angiosarcoma(HAS).Methods The CT and MRI findings of 12 patients with HAS confirmed by pathology were analyzed retrospectively and compared with pathological findings.Results Based on morphological classification,the 12 cases of HAS were categorized into three types:massive patterns(n=3),mixed patterns of mass with nodules(n=2),and diffuse infiltration patterns(n=7).Hemorrhage was observed in 9 cases,and necrosis was present in all 12 cases.The massive patterns exhibited peripheral or nodular,patchy,annular,and cord-like enhancement patterns during the arterial phase,with increasing enhancement during the portal and delayed phases.The mixed patterns of mass with nodules demonstrated mild enhancement around the margin or in patchy and spotty structures during the arterial phase,progressing to expansive enhancement during the portal and delayed phases.Four of the seven diffuse infiltration patterns presented with mesh enhancement during the arterial phase,which expanded and became diffuse during the portal phase,accompanied by progressively enlarged enhancing nodules.In the delayed phase,the lesions were fused.The other three cases showed diffuse nodular enhancement during the arterial phase followed by increased enhancement during both portal phase and delayed phase.Regardless of subtype,focal fusion occurred during the delayed phase when multiple intrahepatic lesions were present,and the hemorrhagic and necrotic parts did not enhance.Conclusion The imaging characteristics of HAS include heterogeneous and progressive enhancement,often accompanied by hemorrhage,cystic change,and necrosis.

Objective:To explore the implementation of standardized preventive nursing training for venous thromboembolism (VTE) based on the analyze, design, development, implement and evaluation model (ADDIE model), and evaluate the effectiveness of the training.Methods:From September 2021 to December 2022, a special training group was established. The specialized training courses were designed and developed guided by the "National Medical Quality and Safety Improvement Goals", based on the ADDIE model, combined with literature research and Delphi expert consultation. In May 2023, 20 thrombosis liaison nurses from 16 ClassⅢ Grade A hospitals across the country were trained on VTE standardized preventive nursing. After training, the Kirkpatrick evaluation method was used to evaluate the training effectiveness from the aspects of nurse satisfaction with the training, knowledge and skills, implementation of key job technologies, and organizational satisfaction.Results:The satisfaction of thrombosis liaison nurses with the training objectives, content, methods, and teachers of VTE standardized preventive nursing training based on the ADDIE model was all 100%. Compared with before training, there was a statistically significant improvement in the theoretical, operational, and overall scores of thrombosis liaison nurses after training ( P<0.05). In terms of the implementation of key technologies for the position, the execution rate of the thrombosis liaison nurse returning to the unit for retraining other personnel was 90%, with a total of 516 nurses receiving training. After training, the theoretical, operational, and overall scores of the 351 nurses who participated in pre-and post training assessments all improved compared to before training, with statistically significant differences ( P<0.05) . Conclusions:VTE standardized preventive nursing training based on the ADDIE model can effectively improve the comprehensive capacity of nurses in VTE prevention, and nurses have a high recognition of the training program.

Background::Cardiovascular disease (CVD) has emerged as the leading cause of death from prostate cancer (PCa) in recent decades, bringing a great disease burden worldwide. Men with preexisting CVD have an increased risk for major adverse cardiovascular events when treated with androgen deprivation therapy (ADT). The present study aimed to explore the prevalence and risk evaluation of CVD among people with newly diagnosed PCa in China.Methods::Clinical data of newly diagnosed PCa patients were retrospectively collected from 34 centers in China from 2010 to 2022 through convenience sampling. CVD was defined as myocardial infarction, arrhythmia, heart failure, stroke, ischemic heart disease, and others. CVD risk was estimated by calculating Framingham risk scores (FRS). Patients were accordingly divided into low-, medium-, and high-risk groups. χ2 or Fisher’s exact test was used for comparison of categorical variables. Results::A total of 4253 patients were enrolled in the present study. A total of 27.0% (1147/4253) of patients had comorbid PCa and CVD, and 7.2% (307/4253) had two or more CVDs. The enrolled population was distributed in six regions of China, and approximately 71.0% (3019/4253) of patients lived in urban areas. With imaging and pathological evaluation, most PCa patients were diagnosed at an advanced stage, with 20.5% (871/4253) locally progressing and 20.5% (871/4253) showing metastasis. Most of them initiated prostatectomy (46.6%, 1983/4253) or regimens involving ADT therapy (45.7%, 1944/4253) for prostate cancer. In the present PCa cohort, 43.1% (1832/4253) of patients had hypertension, and half of them had poorly controlled blood pressure. With FRS stratification, as expected, a higher risk of CVD was related to aging and metabolic disturbance. However, we also found that patients with treatment involving ADT presented an originally higher risk of CVD than those without ADT. This was in accordance with clinical practice, i.e., aged patients or patients at advanced oncological stages were inclined to accept systematic integrative therapy instead of surgery. Among patients who underwent medical castration, only 4.0% (45/1118) received gonadotropin releasing hormone antagonists, in stark contrast to the grim situation of CVD prevalence and risk.Conclusions::PCa patients in China are diagnosed at an advanced stage. A heavy CVD burden was present at the initiation of treatment. Patients who accepted ADT-related therapy showed an original higher risk of CVD, but the awareness of cardiovascular protection was far from sufficient.

Objective:To evaluate the efficacy and safety of triamcinolone acetonide-saline submucosal injection for prevention of esophageal stricture after endoscopic submucosal dissection (ESD) for extensive superficial esophageal neoplasms.Methods:A total of 75 patients who underwent ESD for superficial esophageal neoplasms involving larger than 2/3 of the esophageal circumference at the Department of Gastroenterology, Northern Jiangsu People's Hospital from January 2018 to December 2020 were enrolled. Patients were randomly assigned to triamcinolone acetonide-saline submucosal injection group (group A, n=25), triamcinolone acetonide injections immediately after ESD group (group B, n=25) and the control group undergoing only ESD (group C, n=25). Serial gastroscopy was performed to assess wound healing and esophageal stricture. Endoscopic balloon dilatation (EBD) was performed when patients experienced esophageal stricture. The completion of ESD, time of operation, the amount of triamcinolone acetonide, the incidences of esophageal stricture and the time of EBD treatment of the three groups were compared. Results:All ESD procedures were successfully performed without complications such as intraoperative perforation, massive bleeding or postoperative delayed perforation. The operation time of group A, B and C were 72.87±12.99 min, 94.15±14.22 min and 74.08±11.86 min, respectively, with significant difference ( F=20.925, P<0.001). In pairwise comparison the above indicator in group A and group C was significantly shorter than that of group B (LSD- t=5.759, P<0.001; LSD- t=5.432, P<0.001), but there was no difference between group A and group C (LSD- t=0.327, P=0.745). There was no significant difference in the amount of triamcinolone acetonide between group A and group B (125±15 mg VS 133±19 mg, t=1.673, P=0.101). The rates of wound healing under endoscopy after 1 month of group A, B and C were 76% (19/25), 84% (21/25), and 76% (19/25), respectively, with no significant difference ( χ2=0.636, P=0.728). The esophageal stricture rates were 52% (13/25) in both group A and B, and 84% (21/25) in group C, with significant difference among the three groups ( χ2=7.295, P=0.026), and group A and B showed a significantly lower stricture rate than that of group C ( P=0.015; P=0.015). The median time of EBD treatment of group A, B and C were 4 (range 0 to 9), 5 (range 0 to 13) and 9 (range 0 to 16), respectively, with significant difference ( H=17.58, P<0.001). In pairwise comparison the above indicator in group A and B was significantly less than that of group C ( H=23.96, P<0.001; H=19.00, P=0.002), but there was no significant difference between group A and group B ( H=4.96, P=0.407). Esophageal stricture was observed in all patients with circumferential mucosa resected in the three groups. But the times of EBD treatment were 6.90±1.10 in group A, 10.13±2.42 in group B and 15.29±0.76 in group C with significant difference ( F=57.754, P<0.001). In pairwise comparison the above indicator in group A was less than that in group B (LSD- t=4.294, P<0.001) and this indicator in group B was less than that in group C (LSD- t=6.294, P<0.001). Median EBD times in patients with non-circumferential mucosal defects in the three groups were 0 (range 0 to 9), 0 (range 0 to 6) and 8 (range 0 to10), respectively, with significant difference ( H=19.72, P<0.001). In pairwise comparison, the EBD time in group A and B was less than that in group C ( H=17.93, P<0.001; H=16.62, P<0.001), but there was no statistical difference between group A and B ( H=1.31, P=0.779). Conclusion:Triamcinolone acetonide-saline submucosal injection ESD can safely and effectively prevent esophageal stricture after ESD for large-area superficial esophageal neoplasms, reduce the operation time and time of EBD treatment in patients with circumferential mucosa defect compared with local injections of triamcinolone acetonide after ESD.

Objective To investigate the ability of combined baseline serum markers, i.e., HBV DNA, HBV RNA, HBsAg, and HBcrAg, to predict HBeAg seroconversion in patients with HBeAg-positive chronic hepatitis B (CHB) treated by nucleos(t)ide analogues. Methods A retrospective analysis was performed for 83 HBeAg-positive patients selected as subjects from the prospective CHB follow-up cohort established by Difficult & Complicated Liver Diseases and Artificial Liver Center, Beijing YouAn Hospital, Capital Medical University, from June 2007 to July 2008, and the baseline serum levels of HBV DNA, HBV RNA, HBsAg, and HBcrAg were analyzed. The t -test or the Mann-Whitney U 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 Spearman method was used for correlation analysis. A Cox regression model was established to calculate HBeAg seroconversion prediction score, and the time-dependent receiver operating characteristic curve was used to evaluate the ability of combined markers in predicting HBeAg seroconversion. The Kaplan-Meier method was used to calculate cumulative seroconversion rate in each group, and the Log-rank test was used for comparison between groups. Results For the 83 HBeAg-positive patients, the median follow-up time was 108 months, and 44.58%(37/83) of these patients achieved HBeAg seroconversion. Compared with the non-seroconversion group, the HBeAg seroconversion group had significantly lower baseline serum levels of HBV DNA [6.23(1.99-9.28) log 10 IU/mL vs 7.69(2.05-8.96) log 10 IU/mL, Z =-2.345, P =0.019] and HBV RNA [4.81(1.40-7.53) log 10 copies/mL vs 6.22(2.00-8.49) log 10 copies/mL, Z =-1.702, P =0.010], and there were no significant differences in the levels of HBsAg and HBcrAg between the two groups ( P > 0.05). The Cox regression equation constructed based on the above serum markers showed a median score of 0.95(range 0.37-3.45) for predicting HBeAg seroconversion. In the total population, the combined score was negatively correlated with HBsAg, HBV DNA, HBV RNA, and HBcrAg ( r =-0.697, -0.787, -0.990, and -0.819, all P < 0.001). Based on the median prediction score, the patients were divided into high HBeAg seroconversion group and low HBeAg seroconversion group; as for the prediction of HBeAg seroconversion rate at 36, 60, and 84 months, the high HBeAg seroconversion group had a seroconversion rate of 43.90%, 51.20%, and 63.10%, respectively, while the low HBeAg seroconversion group had a seroconversion rate of 9.60%, 17.00%, and 19.8%, respectively, and there was a significant difference between the two groups ( χ 2 =11.6, P < 0.001). Conclusion The combined prediction score based on baseline serum HBV markers can predict HBeAg seroconversion in CHB patients treated by nucleos(t)ide analogues.

Objective:To investigate the clinical effect of CAG stimulating regimen for refractory adult early T cell precursor acute lymphoblastic leukemia (ETP-ALL) complicated with fusarium infection and the clinical features as well as antifungal strategy of cutaneous fusarium infection.Methods:The diagnosis and treatment of 1 adult patient diagnosed as ETP-ALL complicated with cutaneous fusarium infection in the First Hospital of Jilin University in September 2020 were retrospectively analyzed, and related literatures were reviewed.Results:VICP chemotherapy regimen showed no effectiveness in this patient who was presented with persistent agranulocytosis complicated with cutaneous fusariosis infection. After amphotericin B therapy for infection, he achieved the stable disease and successfully underwent CAG stimulating regimen salvage treatment. The minimal residual disease turned into negative after consolidation chemotherapy based on the myeloid regimen. Finally this patient survived from haploid allogeneic hematopoietic stem cell transplantation after consolidation chemotherapy and fusarium was under the control by using posaconazole as secondary prevention therapy.Conclusions:CAG stimulating regimen can be recommended as reinduction therapy for relapsed/refractory ETP-ALL. Sequential therapy of amphotericin B followed by posaconazole can be a useful antifungal strategy for fusarium infection.

Objective:To evaluate the clinical value of Xing's ureteroileal anastomosis technique in radical cystectomy.Methods:The data of 38 patients who underwent radical cystectomy with Xing's ureteroileal anastomosis technique at Cancer Hospital, Chinese Academy of Medical Sciences and Beijing Chaoyang Hospital from July 2013 to June 2021 were retrospectively reviewed. There were 30 males and 8 females. The mean age was 61.6±15.1 years old. The mean body mass index (BMI) was 25.1±2.7 kg/m 2. The American Society of Anesthesiology (ASA) graded 25 cases as grade 1, 10 cases as grade 2 and 3 cases as grade 3. There were 35 cases with stage cT 2N 0M 0 and 3 cases with cT 3N 0M 0. All patients underwent radical cystectomy and ileal conduit, and the ureteroileal anastomosis was performed using the Xing's ureteroileal anastomosis technique. Afferent loop entry was divided equally into two lumens. After 1.5 cm-long lengthwise incisions, each ureter was directly and end-to-end anastomosed to the aforementioned lumens. Postoperative information was recorded, including ureteric stricture, ureteric reflux, hydronephrosis, anastomotic leakage, renal calculus, urinary tract infection, and pyelonephritis. Results:Ureteroileal anastomosis was performed successfully in 38 cases with 76 units. The median follow-up time was 35.6 (17.0, 46.3) months. Three patients developed unilateral anastomotic stenosis after operation. Five patients had unilateral ureteral reflux. Two patients had unilateral hydronephrosis. No anastomotic leakage, urinary tract infection, or pyelonephritis occurred after the operation. Renal calculus appeared in 3 cases, all on the left unit.Conclusions:Xing's ureteroileal anastomosis technique is a simple method with few postoperative and good functional outcomes.

Objective:To evaluate the efficiency and safety of modified endoscopic anti-reflux mucosectomy (ARMS) for refractory gastroesophageal reflux disease (rGERD) with moderate hiatus hernia.Methods:A total of 30 patients with rGERD with moderate hiatus hernia (3-5 cm) diagnosed at the Department of Gastroenterology of Northern Jiangsu People's Hospital from June 2017 to June 2020 were randomly divided into 2/3 circumferential mucosal resection group ( n=15) and 3/4 circumferential mucosal resection group ( n=15) using random number table method, and received modified ARMS of the corresponding mucosal resection range. The GERD symptoms, esophagitis under endoscopy, 24 h pH results, and lower esophageal sphincter (LES) resting pressure were compared before and after the procedure. The therapeutic effect and complications of the two groups were analyzed. Results:In 2/3 resection group, the GERD questionnaire scores (9.53±0.36 VS 11.93±0.57, t=6.874, P<0.001), acid exposure time (19.81%±1.72% VS 31.45%±2.78%, t=8.020, P<0.001) and the DeMeester score based on 24 h esophageal pH monitoring (40.98±4.55 VS 55.33±5.65, t=6.408, P<0.001) at 6 months after the treatment showed a significant reduction compared with those before. In 3/4 resection group, the GERD questionnaire scores (9.0±0.57 VS 12.47±0.68, t=8.650, P<0.001), acid exposure time (20.07%±2.19% VS 29.96%±3.00%, t=7.444, P<0.001) and the DeMeester score (33.67±3.47 VS 51.17±6.03, t=4.973, P<0.001) at 6 months after the treatment were lower than those before. There was no significant difference in the GERD questionnaire scores ( t=0.790, P=0.436), acid exposure time ( t=0.093, P=0.926) or the DeMeester score ( t=1.278, P=0.212) between the two groups at 6 months after treatment. In the two groups, there was no significant difference in the ratio of esophagitis grade C and D (10/15 VS 5/15, χ2=3.894, P=0.063; 8/15 VS 4/15, χ2=2.778, P=0.125) or LES resting pressure [3.29 (2.66,8.29) mmHg VS 3.98 (3.67,9.43) mmHg, P=0.334;5.78 (1.9,8.46) mmHg VS 5.88 (3.28,8.99) mmHg, P=0.125] before and after the treatment. No postoperative delayed bleeding or perforation was observed. The incidence of postoperative esophageal stenosis of 2/3 resection group was lower than that of the other group (1/15 VS 6/15, χ2=4.658, P=0.021). Conclusion:Modified ARMS is effective for controlling reflux symptoms and esophageal acid exposure in rGRED patients with moderate hiatus hernia (3-5 cm), but cannot significantly increase the postoperative resting pressure of LES. Compared with 3/4 circumferential mucosal resection, 2/3 circumferential mucosal resection can reduce the incidence of postoperative esophageal stenosis.

Background/Aims: To investigate the autoantibody against fumarate hydratase (FH), which is a specific liver failure-associated antigen (LFAA) and determine whether it can be used as a biomarker to evaluate the prognosis of acute-on-chronic liver failure (ACLF). Methods: An immunoproteomic approach was applied to screen specific LFAAs related to differential prognosis of ACLF (n=60). Enzyme-linked immunosorbent assay (ELISA) technology was employed for the validation of the frequency and titer of autoantibodies against FH in ACLF patients with different prognoses (n=82). Moreover, we clarified the expression of autoantibodies against FH in patients with chronic hepatitis B (n=60) and hepatitis B virus-related liver cirrhosis (n=60). The dynamic changes in the titers of autoantibodies against FH were analyzed by sample collection at multiple time points during the clinical course of eight ACLF patients with different prognoses. Results: Ultimately, 15 LFAAs were screened and identified by the immunoproteomic approach.Based on ELISA-based verification, anti-FH/Fumarate hydratase protein autoantibody was chosen to verify its expression in ACLF patients. ACLF patients had a much higher anti-FH autoantibody frequency (76.8%) than patients with liver cirrhosis (10%, p=0.000), patients with chronic hepatitis B (6.7%, p=0.022), and normal humans (0%, p=0.000). More importantly, the frequency and titer of anti-FH protein autoantibodies in the serum of ACLF patients with a good prognosis were much higher than that of patients with a poor prognosis (83.9% vs 61.5%, p=0.019; 1.41±0.85 vs 0.94±0.56, p=0.017, respectively). The titer of anti-FH autoantibodies showed dynamic changes in the clinical course of ACLF. Conclusions The anti-FH autoantibody in serum may be a potential biomarker for predicting the prognosis of ACLF.

Objective To investigate the consistency between Shengxiang (S) and Xinbo (X) real-time PCR methods in the quantification of HBV RNA. Methods In the prospective follow-up cohort of 108 chronic hepatitis B (CHB) patients established from July 2007 to August 2008, 20 patients with HBeAg seroconversion were selected, and 20 patients without seroconversion were selected by propensity score matching at a ratio of 1∶ 1. The two quantification methods from S and X companies were used, and a retrospective analysis was performed for HBV RNA in serum samples at baseline and weeks 12, 24, and 48. The paired t -test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the chi-square test was used for comparison of categorical data. The Pearson correlation coefficient, intraclass correlation coefficient (ICC), and the Bland-Altman method were used to evaluate the consistency of the two quantification methods. Results A total of 132 serum samples were tested by S reagent, and 154 were tested by X reagent; the detection rate of HBV RNA was 100% by both reagents. A total of 131 serum samples were tested by both reagents, with 34 samples at baseline and 29, 35, and 33 samples, respectively, at weeks 12, 24, and 48 of follow-up; at these four time points, the HBV RNA quantification data detected by X reagent were significantly higher than those detected by S reagent (5.75±1.64/5.43±1.73/5.13±1.54/4.76±1.55 log 10 copies/mL vs 4.80±1.48/4.52±1.53/4.10±1.50/3.92± 1.43 log 10 copies/mL, t =8.348, t =5.341, Z =-5.086, Z =-4.762, all P < 0.001). The correlation analysis of the two methods showed a Pearson correlation coefficient of 0.915 (95% confidence interval [ CI ]: 0.836-0.957) and an ICC of 0.771(95% CI : -0.021 to 0.931) at baseline, a Pearson correlation coefficient of 0.849(95% CI : 0.701-0.927) and an ICC of 0.733(95% CI : 0.138-0.902) at week 12, a Pearson correlation coefficient of 0.951(95% CI : 0.905-0.975) and an ICC of 0.776(95% CI : -0.058 to 0.942) at week 24, and a Pearson correlation coefficient of 0.933(95% CI : 0.867-0.967) and an ICC of 0.804(95% CI : -0.014 to 0.944) at week 48 (all P < 0.05). The Bland-Altman analysis showed that the difference of 96.18%(126/131) samples tested by the two methods was within the mean difference±1.96 standard deviation. Conclusion HBV RNA quantification by X reagent is higher than that by S reagent, while the two real-time PCR quantification methods show a good consistency in CHB patients with HBeAg seroconversion and those without seroconversion.
