Objective This retrospective study was to explore the efficacy and determine the risk factors of survival for recurrent hepatocellular carcinoma ( HCC) treated by repeat hepatectomy. Methods From January 1995 till December 2010, 60 patients with recurrent HCCs, were treated by repeat hepatectomy.The significance of seventeen clinical or pathological variables in the risk factors of overall survival were assessed. Results The overall survival 1,3, and 5-year survival rates were 76. 3% , 40.7% and 25. 0% (from repeat hepatectomy), and 95. 0% , 62. 6% and 43. 3% ( from initial hepatectomy) , respectively.Univariate analysis indicated that tumor size at initial hepatectomy, recurrence interval from initial hepatectomy, serum albumin(ALB) level, resection margin, diameter of largest recurrence tumor and rumor vascular invasion were significant prognostic factors(P <0. 05, Kaplan-Meier Log-rank test). Multivariate analysis showed recurrence interval from initial hepatectomy, resection margin, diameter of largest recurrence tumor and rumor vascular invasion were significant prognostic factors(P<0.05, Cox proportional hazards model).Conclusion Repeat hepatectomy is effective for recurrent HCC. Recurrence interval from initial hepatectomy, resection margin, diameter of largest recurrence tumor and rumor vascular invasion were significant prognostic factors.

Objective To compare the efficacy of percutaneous radiofrequency ablation (PRFA) and repeat hepatectomy for solitary recurrent hepatocellular carcinoma (HCC) with the diameter≤3 cm. Methods The clinical data of 151 patients with recurrent HCC (diameter≤3 cm) who were admitted to the Cancer Center of Sun Yat-Sen University from January 1999 to December 2009 were retrospectively analyzed. Of all the patients, 79received PRFA (PRFA group) and 72 received repeat hepatectomy (repeat hepatectomy group). The survival rate, morbidity and recurrence of the tumor between the two groups were compared. All data were analyzed using t test, chi-square test or Log-rank test, and the survival of the patients were analyzed using the Kaplan-Meier method. Results The mobidities of the PRFA group and repeat hepatectomy group were 13% (10/79) and 36%(26/72), respectively, with a significant difference between the two groups (x2=11.411, P＜0.05). The cumulative 1-, 2-, 3-, 4-, 5-year survival rates were 89.7%, 75.2%, 67.1%, 61.5%, 56.6% in the PRFA group, and 86.0%, 67.6%, 53.6%, 44.1%, 40.2% in the repeat hepatectomy group, with no significant difference between the two groups (x2=1.610, P＞0.05). The cumulative 4-, 5-year survival rates of the PRFA group were significant higher than those in the repeat hepatectomy group (x2=4.682, 4. 196, P ＜ 0.05). The local tumor recurrence rate of the PRFA group was 5% (4/79), and the incisal margin recurrence rate was 3% (2/72) in the repeat hepatectomy group, with no significant difference between the two groups (x2=0.565, P＞0.05). Conclusion As a less invasive treatment method, PRFA is superior to repeat hepatectomy for solitary recurrent HCC with the diameter≤3 cm.

Objective To improve the understanding,the incidence and imaging findings of tuberous sclerosis complex (TSC) combined with cardiac rhabdomyomas (CRs) in fetuses and infants.Methods The imaging findings of 9 infants with TSC combined with CRs and 4 fetuses with TSC combined with CRs from our hospital between June,2006 and November,2013 were retrospectively reviewed.Results The brain MRI of 9 with TSC combined with CRs showed bilateral subependy-mal nodules,subcortical white matter and cortical tubers.Subependymal nodules were isointense or hypointense on spin-echo T1WI and hypointense or hyperintense on spin-echo T2WI.Subcortical white matter and cortical tubers were hypointense or hyperintense on T1WI and hypointense or hyperintense on T2WI.There was varying contrast enhancement.Three of 9 infants presented single cardiac tumor and 6 of 9 infants presented multiply cardiac lesions.CRs on contrast cardiac MRI showed round solid masses in ventricular septums,ventricular outflow tract,ventricle or atrial free walls.The masses were isointense relative to the cardiac muscles on T1WI,T2WI and B-TFE sequence.There was varying contrast enhancement.Four fetuses with TSC on ultrafast MRI showed bilateral multiply subependymal nodules,the nodules were isointense or hyperintense on TFE T1WI and isointense or hypointense signals on SSTSE or B-FFE sequence,Four fetuses with CRs showed isointense to hyperintense solid masses in ventricular septums on ultrafast MRI,ventricle or atrial free walls on B-FFE sequence and SSTSE sequence images.Conclusions TSC in infant and fetus is a kind of neurocutaneous syndrome,usually combines with CRs.Fetal ultrafast and routine MRI is a useful method to make a definite diagnosis for cranial and cardiac lesions.The development of MRI might improve the timeliness and accuracy of the assessment for this disease.

Objective? To investigate the coping style of postpartum patients with pelvic floor dysfunction and to analyze the effect of family support on coping style of postpartum women with pelvic floor dysfunction. Methods? From May to October 2017, we selected postpartum patients with pelvic floor dysfunction of department of gynaecology in the First Affiliated Hospital of Wenzhou Medical University as subjects by convenience sampling. All of the patients were investigated with the Simplified Coping Style Questionnaire (SCSQ) and Perceived Social Support form Family(PSS-Fa) to understand the coping style and family support of patients. The correlation between them was explored. A total of 200 questionnaires were sent out and 186 valid of them were collected with 93.0% for the valid rate. Results? Among 186 postpartum patients with pelvic floor dysfunction, the score of positive coping was (1.56±0.73) lower than that of norm; the score of negative coping was (1.85±0.65) higher than that of norm; the differences were statistical (P＜0.05); the score of family support was (3.01±0.68) having a positive correlation with positive coping (r=0.45,P＜ 0.01) and a negative correlation with negative coping (r=-0.25,P＜ 0.01). Hierarchical regression analysis showed that family support was the influencing factors of positive coping among postpartum women with pelvic floor dysfunction after controlling general information. Conclusions? Postpartum women with pelvic floor dysfunction have negative coping style. Family support is the main influencing factor of positive coping. We should increase the publicity of pelvic floor dysfunction, encourage patients to cope positively and to seek family support properly.

Objective:To investigate the effects of meditation therapy on fear of disease progress and mental health among acute myocardial infarction (AMI) patients.Methods:Totally, 120 cases of acute myocardial infarction patients admitted to Affiliated Hospital of Jiangnan University were divided into experimental group and control group according to the enrolled time. 60 patients with AMI treated from June to November 2018 served as the control group and 60 patients with AMI treated from January to May 2019 served as the experimental group.

Objective To investigate the efficacy and safety of endoscopic radiofrequency ablation on patients with advanced stage unresectable cholangiocarcinoma. Methods Clinical data of 45 cases with unresectable cholangiocarcinoma who underwent endoscopic retrograde cholangiopancreatography from October 2011 to October 2014 were collected. The patients were divided into two groups: the group A included 23 cases undergoing radiofrequency ablation, and the group B included 22 cases without ablation. The occurrence of complications, the postoperative levels of CA19-9 and total bilirubin ( TBIL) in blood plasma, the patency of stents, and survival period were compared between the two groups. Results All of the 45 patients completed treatment, and no perforation, bleeding and bile leakage occurred. In the group A, 2 patients got fever and 5 patients got pancreatitis after operation, and the number in the group B was 3 and 4, respectively. Their symptoms disappeared after suitable treatment. The postoperative pain rate in group A ( 21. 7％, 5/23) was significantly lower than that of group B ( 54. 5％, 12/22,χ2=5. 148, P=0. 023) . At 7th day of post-operation, the levels of CA19-9 in the two groups were 960. 5 ± 362. 7 U/mL and 979. 3 ± 378. 1 U/mL, respectively, and the levels of TBIL were 95. 25±28. 36μmol/L and 98. 75±20. 76μmol/L, respectively, which were not significantly different between the two groups( P>0. 05) , but were significantly decreased compared with the levels of pre-operation ( P<0. 05) . The patency of self-expandable metal stent in group A ( 60. 0％, 6/10) was significantly higher than that of group B ( 10. 0％, 1/10,χ2=5. 495, P=0. 019) 9 months after operation. Kaplan-Meier analysis showed that the median survival time in the two groups had no statistical difference [ 271. 0 days ( 95％CI: 168. 4-373. 4days ) VS 245. 0 days ( 95％CI:200. 3-289. 7 days), χ2=1. 380, P=0. 258]. Conclusion For the patients with advanced unresectable cholangiocarcinoma, endoscopic radiofrequency ablation is able to relieve cancer pain, prolong the patency of stents, and improve the life quality, which deserves clinical applications.

Objective:To investigate the imaging and clinical characteristics of posttransplantation lymphoproliferative disorders (PTLD) after liver transplantation in children.Methods:From February 2017 to November 2020, the imaging and clinical data of 17 children with PTLD after liver transplantation confirmed by pathology or clinical diagnosis were retrospectively analyzed in Shanghai Children′s Medical Center, School of Medicine, Shanghai Jiao Tong University. The site, range, density/signal/echo of the lesions were observed.Results:The mean age at transplantation was 8 (7, 11) months, and 14 patients were younger than 1 year old. The interval between liver transplantation and PTLD diagnosis was 22 (10, 34) months, ranging from 3 to 54 months. The interval was less than 1 year in 6 patients (early onset) and equal or greater than 1 year in 11 patients (late onset). Fifteen patients had Epstein-Barr virus infection. Among the 12 pathologically confirmed PTLD cases, 8 cases were diffuse large B-cell lymphoma, 3 cases were Burkitt lymphoma, and 1 case was reactive plasma cell hyperplasia. Among the 17 children with PTLD, 8 cases demonstrated involvement of lymph nodes and 16 cases had extranodal involvement. The latter included 15 cases of abdominal involvement. Abdominal sites involved included small intestine in 14 cases, colon in 7 cases, mesentery in 4 cases, kidney in 3 cases, liver in 2 cases, abdominal lymph nodes in 2 cases, peritoneum in 1 case, and stomach in 1 case. The sites of extra-abdominal involvement included lymph nodes in 7 cases, lung in 3 cases, skull in 1 case, brain in 1 case, pleura in 1 case, chest wall in 1 case, and nasopharynx in 1 case. The most common abdominal imaging abnormalities were thickening of the intestinal wall, eccentric mass and dilation of the lumen. Both small intestines and colons could be involved, and the former more commonly. Multiple masses were found in patients with liver and kidney involvement. The most common imaging manifestation of PTLD outside the abdomen was lymph node enlargement, which was found in 7 cases, and the most common was in the neck. The manifestation was shorter diameter of lymph nodes>10 mm, uniform density and signal, with mild enhancement.Conclusions:PTLD can occur months to years after liver transplantation in children, which can affect many parts of the whole body. Extranodal lesions are more than intranodal lesions. Abdominal involvement is most common in PTLD, and the infection rate of EB virus is high. Combined with medical history, EB virus infection status and imaging examination are helpful for early diagnosis.

Objective: To investigate the radiographic manifestations and clinical relevance to central nervous system complications of leukemia (CNSCL)in children. Methods: The CT and magnetic resonance imaging(MRI) fin-dings and clinical features of 49 pediatric patients with CNCSL in Shanghai Children′s Medical Center Affiliated to Shanghai Jiaotong University School of Medicine from May 2010 to June 2018 were retrospectively analyzed. Results: (1) Cerebrovascular abnormalities in 23 cases included hemorrhage(20 cases), infarction(2 cases) and sinus thrombosis(1 case). One case of epidural hematoma and 19 cases of intracerebral multiple bleeding were seen in the hemorrhage group, which demonstrated high-density on CT and different signal on MRI as time went by.Microhe-morrhage displayed as low signal on susceptibility weighted imaging.(2) Among 23 cases of leukemic infiltration, the dura and/or skull were involved in 18 cases, which presented as fusiform or mass, with high density on CT, low signal on T1WI, intermediate signal on T2WI and strong enhancement; 6 leptomeningeal infiltration demonstrated as meningeal thickening and enhancement; 2 parenchymal involvement manifested with high-density mass; 2 oculomotor nerve and 1 optic nerve infiltration demonstrated thickening and enhancement.(3)White matter disease was seen in 2 cases, with hyper-intensity on T2WI.(4) One case of secondary tumor was glial tumor in the brainstem. Conclusions The radiographic manifestations of CNCSL in children are various.CT and MRI are of important diagnostic values.Choosing the best imaging examination method and sequence according to clinical symptoms and test results can provide more valuable information for clinical diagnosis and treatment.

Objective:To preliminarily verify the feasibility of applying a wearable teleconsultation device in the diagnosis of common skin diseases.Methods:Totally, 600 outpatients with skin diseases were prospectively enrolled from the Department of Dermatology from November 1 to December 31 2023, and both on-site and remote diagnoses were performed. In the face-to-face clinic, there was one resident physician A and one chief physician B, while there was one resident physician C and one chief physician D in the remote consultation clinic. Using the diagnostic results of physician B in the face-to-face clinic as a reference, diagnostic agreement rates of physicians A, C, and D were calculated separately. Additionally, diagnostic results were compared between physician A and physician C, as well as between physician A and physician D. Statistical analysis was carried out using McNemar's test and Kappa consistency analysis.Results:Among the 600 patients with skin diseases, there were 285 males (47.50%) and 315 females (52.50%), and their age was 38.75 ± 21.12 years. The most common skin diseases were dermatitis and eczema (138 cases, 23.00%), followed by viral skin diseases (79 cases, 13.17%), urticaria (53 cases, 8.83%), hair diseases (53 cases, 8.83%), skin tumors (46 cases, 7.67%), fungal skin diseases (38 cases, 6.33%), etc. Compared with the physician B, the physician A made consistent diagnoses in 477 cases (79.5%) and inconsistent diagnoses in 123 cases (20.5%), the physician C made consistent diagnoses in 465 cases (77.5%) and inconsistent diagnoses in 135 cases (22.5%), and the physician D made consistent diagnoses in 568 cases (94.6%) and inconsistent diagnoses in 32 cases (5.33%). There was no significant difference in the diagnostic accuracy between the physician A and physician C ( P = 0.430), with a Kappa value of 0.852, indicating very strong consistency. The diagnostic accuracy of the physician D was significantly higher than that of the physician A ( P = 0.001), with a Kappa value of 0.274, indicating weak consistency. Conclusion:Chief dermatologists can provide medical guidance to resident physicians through a wearable teleconsultation system.
