Objective To investigate the epidemiological characteristics and influencing factors of Femoral Artery Compression-Related Skin Complications Around the Puncture Site(FACR-SCAPS)in patients with primary hepatocellular carcinoma(HCC)undergoing transarterial chemoembolization(TACE).Methods A multicenter cross-sectional study was conducted using convenience sampling.A total of 1 573 HCC patients who underwent TACE between April 2023 and October 2024 were recruited from interventional radiology departments,oncology units,and specialized centers across 10 hospitals in Beijing,Tianjin,Shandong,Hebei,Qinghai,and Inner Mongolia.Descriptive statistics,univariate analysis,and multivariate logistic regression were used to explore the epidemiological characteristics and influencing factors of FACR-SCAPS in this population.Results Among the 1 573 primary HCC patients undergoing TACE interventional therapy,FACR-SCAPS occurred in 28.99％(456/1 573),with a total of 476 complication instances recorded(30.26 per 100 patients).Patients with a single complication accounted for 96.93％,whereas those with multiple complications constituted 3.07％.The most prevalent types of complications were skin erythema,skin ecchymosis,and hard lumps formation,collectively accounting for 96.49％of all complications.Hematoma,blisters,and rupture complications collectively accounted for only 4.61％.Logistic regression analysis revealed that peak diastolic blood pressure during compression(OR=1.024,95％CI:1.013-1.035,P＜0.001),use of rotary compression hemostasis devices(OR=3.220,95％CI:2.120-4.891,P＜0.001),elevated PT-INR(OR=19.630,95％CI:6.039-63.810,P＜0.001),and anticoagulant use within the last three months(OR=1.909,95％CI:1.064-3.427,P=0.030)were significant influencing factors associated with FACR-SCAPS post-TACE.Conclusion FACR-SCAPS is commonly seen among primary HCC patients after TACE,its risk factors include peak diastolic blood pressure during compression,use of rotary compression devices,elevated PT-INR,and recent anticoagulant use.

Objective:To investigate the epidemiology of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in patients with maintenance hemodialysis (MHD) in Jiangsu province during SARS-CoV-2 pandemic in China from December 7, 2022 to January 27, 2023, and to analyze the influencing factors of all-cause death.Methods:It was a multi-center cross-sectional investigation. Structured questionnaire was used to collect patient information by medical staff of each hemodialysis center (room) as investigators. Part of the demography data and laboratory examination data came from the Jiangsu Province Hemodialysis Data Information System. MHD patients from hemodialysis centers (rooms) at all levels of medical institutions and independent hemodialysis institutions in Jiangsu province during the outbreak of SARS-CoV-2 infection were included, and the clinical characteristics and all-cause mortality of confirmed and suspected cases of SARS-CoV-2 infection were analyzed.Results:Questionnaire surveys and data analysis on 57 278 patients in 407 hemodialysis centers (rooms) were completed, accounting for 90.41% of the total number of MHD patients (63 357 cases) in Jiangsu province during the same period. There were 24 038 cases (41.97%) of SARS-CoV-2 infection and 14 805 cases (25.85%) of suspected infection, which were widely distributed in all dialysis centers in Jiangsu province. After clinical classification of 38 843 confirmed and suspected SARS-CoV-2 infection cases, 3 662 cases were severe and critical cases, accounting for 9.43% of the infected and suspected cases. Among the patients who had completed the questionnaires, there were 1 812 all-cause deaths, with an all-cause mortality rate of 3.16%. Multivariate logistic regression analysis showed that elderly (taking ≤50 years as a reference, 51-59 years: OR=1.583, 95% CI 1.279-1.933, P=0.001; 60-69 years: OR=3.972, 95% CI 3.271-4.858, P<0.001; 70-79 years: OR=7.236, 95% CI 5.917-8.698, P<0.001; &ge;80 years: OR=11.738, 95% CI 9.459-14.663, P<0.001), male ( OR=1.371, 95% CI 1.229-1.529, P<0.001), and co-infection with hepatitis B virus (HBV) (positive serum HBV surface antigen, OR=0.629, 95% CI 0.484-0.817, P<0.001) were independent influencing factors for all cause mortality. Receiver-operating characteristic curve analysis showed that the area under the curve for male, age and current HBV infection prediction of all-cause death was 0.529 ( P<0.001), 0.724 ( P<0.001) and 0.514 ( P=0.042), respectively, and the cut-off value for age prediction of all-cause death was 65.5 years old. Compared with patients without HBV infection, MHD patients with HBV infection significantly reduced the proportion of severe and critically ill patients, all-cause hospitalizations and all cause deaths when infected with SARS-CoV-2 (4.99% vs. 6.41%, χ2=6.136, P=0.013; 8.90% vs. 11.44%, χ2=11.662, P<0.001; 2.01% vs. 3.37%, χ2=10.713, P=0.001, respectively). Conclusion:The MHD patients in Jiangsu province are susceptible to SARS-CoV-2. Elderly age and male gender are independent risk factors for death in MHD patients during the epidemic, while the HBV infection may be a protective factor for death of MHD patients infected with SARS-CoV-2.

Objective:To determine the prognostic values of clinical and laboratory features at the time of presentation on renal survival of patients with myeloperoxidase (MPO)-antineutrophil cytoplasmic antibody(ANCA)-associated glomerulonephritis (MPO-ANCA-GN).Methods:A total of 172 patients with MPO-ANCA-GN and hospitalized at the First Affiliated Hospital of Nanjing Medical University from January 2005 to December 2018 were enrolled. The baseline clinical characteristics and renal biopsy pathological data were analyzed, and the renal prognosis was followed up. The clinical and pathological characteristics of different renal prognosis in all patients and 112 patients who underwent renal biopsy were analyzed, and the related factors affecting renal survival were further discussed.Results:Among these 172 patients, 81 were males and 91 were females. The median serum creatinine at diagnosis was 343.7(174.2, 606.6) μmol/L and the median estimated glomerular filtration rate (eGFR) was 15.81(7.61, 38.04) ml·min -1·(1.73 m 2) -1. In total, 76 patients (44.2%) received initial renal replacement therapy (RRT). During a median follow-up duration of 20(3, 60) months, 73 patients (42.4%) progressed to end-stage renal disease (ESRD) and required dialysis, including 6 (8.2%) patients who entered RRT during follow-up and 67 (91.8%) patients who received RRT at the beginning. Among the 112 patients who underwent renal biopsy, the proportion of patients who progressed to ESRD in the sclerotic group was the highest (15/25, 60.0%). The baseline serum creatinine level ( P<0.001), urine red blood cell count ( P=0.012) and the proportion of glomerular sclerosis ( P=0.002) in the non-dialysis dependent group were significantly lower than those in the dialysis dependent group, while the levels of eGFR ( P<0.001), serum albumin ( P=0.002) and hemoglobin ( P<0.001) were higher than those of the dialysis-dependent group. Kaplan-Meier survival analysis showed that the renal survival rate of the focal group was the highest ( χ2=19.488, P<0.001, log-rank test), while the renal survival rate of the sclerotic group was significantly lower than that of the crescentic group ( χ2=5.655, P=0.017); higher levels of serum creatinine (>320 μmol/L, χ2=77.229, P<0.001) and urine red blood cell count (>300 cells/μl, χ2=8.511, P=0.004), lower levels of rheumatoid factor (<20 IU/ml, χ2=8.610, P=0.003), serum albumin (<30 g/L, χ2=11.060, P=0.001) and hemoglobin (<90 g/L, χ2=21.921, P<0.001) were associated with lower renal survival rate; in terms of treatment, the renal survival rate of the glucocorticoids plus mycophenolate mofetil group was significantly higher than that of the glucocorticoids plus cyclophosphamide ( χ2=5.056, P=0.025) or the glucocorticoids alone group ( χ2=16.459, P<0.001). Multivariate Cox regression showed that baseline serum creatinine >320 μmol/L ( HR=8.803, 95% CI 3.087-25.106, P<0.001) and serum albumin <30 g/L ( HR=2.566, 95% CI 1.246-5.281, P=0.011) were the related factors affecting renal survival. Conclusion:Serum creatinine and albumin levels of MPO-ANCA-GN patients at diagnosis may be the related factors that affect the patient's renal prognosis.

Objective: To investigate the expression of SMARCA4 (BRG1) and SMARCB1 (INI-1) protein in endometrial dedifferentiated carcinoma (DDC) and undifferentiated carcinoma (UDC), and their correlation with clinicopathologic features. Methods: Clinicopathological information was gathered for 26 cases of DDC and UDC and consulting hospitals from January, 2006 to December, 2018 in Fudan University Shanghai Cancer Center, including 10 cases of DDC and 16 cases of UDC. Morphologic features and diagnosis were reviewed by two pathologists. Immunohistochemistry for expression of BRG1 and INI1 protein was performed. The correlations with clinicopathologic features were analyzed. Results: BRG1 and INI1 loss were present in 14 of 26 cases of DDC/UDC, including 12 BRG1-deficient cases and 2 INI1-deficient cases, respectively. Six cases demonstrated variable amounts of rhabdoid cells in 14 BRG1/INI1-deficient cases, and only 1 case showed rhabdoid cells in the 12 intact expression cases. However, there was no significantly statistical difference (P=0.060). Age, invasive depth, lymph node status and FIGO stage were not associated with the expression of the BRG1 and INI1 (P=0.437, P=0.672, P=0.242, P=0.348). Remarkably, the BGR1/INI1-deficient patients had worse survival than those with intact expression (4.7 vs. 22.9, P=0.033). Conclusion BRG1/INI1-deficient is observed in approximately half of DDC and UDC. Identification of these tumors is clinically relevant due to their more aggressive behavior and poor prognosis. Hence, BRG1 and INI1 immunohistochemical stains should be performed for DDC and UDC in order to help the pathologists to distinguish these tumors from other carcinomas, and to predict the clinical prognosis.

Objective: To describe the clinicopathologic features, diagnosis and differential diagnosis of ovarian carcinoid tumors. Methods: A retrospective chart review was performed of all patients diagnosed with primary ovarian carcinoid tumors at Fudan University Shanghai Cancer Centre from 2007 to 2017. Results: The histologic analysis of these carcinoid tumors revealed 3 were insular, 1 was trabecular, 1 was mucinous, and 10 were strumal. Histologic features of insular and trabecular carcinoid were similar to other parts of the neuroendocrine tumor. Strumal carcinoid was composed of thyroid tissue intimately admixed with carcinoid tumor, showing trabecular pattern. Mucinous carcinoid was resembles Krukenberg tumor. Most ovarian carcinoid tomours were diffusely positive with at least one neuroendocrine marker, especially synaptophysin (14/14) and CD56(9/10). The median follow-up time was 53 months, 1 patient with squamous-cell carcinoma of cervixrecur rence in vaginal after 37 months, and only 1 patient died of disease. The remaining patients were disease-free survival. Conclusions Primary carcinoid of the ovary is a very rare low grade malignant monodermal teratomas and somatic-type tumours arising from a dermoid. The diagnosis and differential diagnosis mainly relies on the histopathologic characteristics and the immuno-phenotype. Primary ovarian carcinoid almost always exhibit a benign clinical behavious except mucinous carcinoid.

Objective To study shortdated postoperative variation characteristics of bone turnover markers (BTMs) in uremic patients with secondary hyperparathyroidism (SHPT) underwent parathyroidectomy (PTX). Methods A total of 19 uremic patients with SHPT underwent successful PTX, hospitalized in the Department of Nephrology, The First Affiliated Hospital of Nanjing Medical University from January 2017 to April 2017, were enrolled in the study. The operative model for all enrolled patients was total parathyroidectomy with forearm autotransplantation. The baseline epidemiological and clinical data before PTX and the levels of serum intact parathyroid hormone (iPTH) and serum BTMs after PTX (in the 1st, 3rd and 7th postoperative day) were collected. The correlations between serum iPTH and serum BTMs before PTX and the trend analysis of serum BTMs after PTX were studied. Results The levels of serum iPTH, serum alkaline phosphatase (ALP), serum typeⅠcollagen cross-linked C-telopeptides (CTX) and serum tartrate-resistant acid phosphatase 5b (TRACP-5b) before PTX were increased, in turn, (1512.4±612.0) ng/L, 267.4(153.1, 424.2) U/L, (5.78±1.15)μg/L and (8.79 ± 4.61) IU/L. Positive correlations between ALP and iPTH (r=0.577, P=0.010), TRACP-5b and iPTH (r=0.640, P=0.003), and ALP and TRACP-5b (r=0.698, P=0.001) were found. The serum levels of ALP increased, while the serum levels of CTX and TRACP-5b decreased within 7 days after PTX. Conclusions Renal osteodystrophy (ROD) with high bone turnover rate is common in uremic patients with severe SHPT. The activities of osteoblast and osteoclast are up-regulated in coupling with positive correlations to serum levels of iPTH. Increased activities of osteoblast and decreased activities of osteoclast were found shortdated postoperatively.

Objective To investigate the clinical efficacy of total parathyroidectomy and autologous transplantation(PTX+ AT) for treating secondary hyperparathyroidism(SHPT) in the patients with uremic maintenance hemodialysis and postoperative calcium supplementation.Methods The clinical data in 57 patients with SHPT treated with PTX+ AT in the urology department of the First Affiliated Hospital of Nanjing Medical University from March 2015 to August 2015 were retrospectively analyzed.The changes of serum intact parathyroid hormone(iPTH),calcium and clinical symptoms were observed before and after operation.Results Serum iPTH levels at different time points of immediately after operation,postoperative 20 min,2 d,4 d were(288.57 ±194.71),(185.00±99.28),(83.83 ± 58.26),(17.91± 15.60) pg/mL respectively,which were significantly decreased compared with (2395.80 ± 829.04) pg/mL before operation (P＜ 0.05);blood calcium at postoperative 4,8,24,72 h was (2.34 ± 0.32),(2.16±0.37),(2.16±0.27),(2.25±0.25) mmol/L respectively,which were significantly decreased compared with(2.61±0.25)mmol/L before operation(P＜0.05);the symptoms such as bone pain,skin itching and so on were significantly improved.Conclusion PTX+AT can effectively treat uremic SHPT,and postoperative timely calcium supplementation can reduce the occurrence of hypocalcemia.

Objective: To observe the therapeutic response of radiosynovectomy with p-32 colloid on hemophilic arthropathy, and to assess the effects of radiosynovectomy with Denver Score on hemophilic arthritis staging. Methods: Radiosynovectomy with p-32 colloid was performed on 326 hemophilic arthritis patients (405 joints) , and recorded bleeding before and after treatment. The MRI performance of 102 joints was evaluated by using Denver scoring system, then was divided into 0-6 and 7-10 groups. Finally, the differences between 2 groups were analyzed. Results: Average pain score of all hemophilic arthritis patients at 6 months, 1, 2 and 3 years post treatment decreased from 3.2±2.4 (n=326) to 1.2±0.6 (n=285, P=0.021) , 1.7±0.5 (n=242, P=0.032) , 2.1±1.1 (n=212, P=0.030) and 2.2±1.6 (n=176, P=0.037) , respectively. The frequency of bleeding in 405 joints at 1, 2 and 3 years post treatment decreased from 15.1±3.6 to 2.1±0.7, 4.3±0.6, and 4.8±0.8 times per year (P<0.01) , respectively; Meanwhile, the proportions of significantly ameliorated joints’ activities were observed as of 68.50% (248/362) , 58.39% (181/310) , 55.67% (162/239) and 42.61% (75/176) , respectively. The frequencies of haemarthrosis at 1 and 2 years post treatment in patients with 0-6 Denver Score (45 target joints) reduced from 13.0±1.9 to 1.3±0.6 (P=0.002) and 3.1±0.9 (P=0.009) times per year, respectively, which also decreased in 7-10 group (57 target joints) from 16.6±2.1 to 3.1±0.9 (P=0.008) and 5.7±1.1 (P=0.004) times per year, respectively. There was no statistical difference between 0-6 and 7-10 groups before treatment in the terms of haemarthrosis frequency (P=0.773) . However, 7-10 group had higher haemarthrosis frequency at 1 and 2 years post treatment compare with 0-6 group (P=0.028 and 0.042, respectively) . Synovial volumes in 29 joints reduced after 6 month when compared with baseline [ (2 362.15±32.41) mm³ vs (3 012.40±39.78) mm³, t=7.621, P<0.001]. Conclusion Radiosynovectomy with p-32 colloid on haemophilic synovitis was a safe and effective procedure. The patients with Denver Score of 0-7 had lower frequency of haemarthrosis.
