Objective:To establish surgical difficulty scoring system of partial nephrectomy based on holographic imaging and explore its application value in partial nephrectomy.Methods:A total of 184 patients including 110 males and 74 females with renal tumors diagnosed as stage cT 1 to cT 2 before surgery in the First Affiliated Hospital of Xiamen University from October 2019 to January 2022 were included. Among the 184 patients, 141 patients were treated with partial nephrectomy and 43 patients were treated with radical nephrectomy (3 partial nephrectomies were finally changed to radical nephrectomies due to vascular and tumor location). 60 patients had hypertension. 24 patients had diabetes. 7 patients had hyperuricemia. The median age was 55(47, 62) years. The median BMI was 23.7(21.8, 26.4) kg/m 2. The median maximum tumor diameter was 3.9(2.9, 5.2) cm. The median preoperative eGFR was 99.7(83.4, 114.2) ml/(min·1.73m 2). The median R. E.N.A.L. score was 8(6, 9). The median PADUA score was 9(8, 10). 153 patients were diagnosed as stage cT 1 and 31 patients were diagnosed as stage cT 2. The hologram reconstruction was performed according to preoperative CT or MRI examination. The maximum diameter of the tumor in the kidney (D), the compression degree of the renal segmental vessels by tumor(C), the area of the renal sinus occupied by tumor(O) and the mass of exophytic rate(M) were comprehensively considered and finally constituted the difficulty scoring system named DCOM score for partial nephrectomy. The DCOM score divided the complexity of tumor surgery into mild (4-6 points), moderate (7-8 points) and high (≥ 9 points). Meanwhile, the MIC (surgical margins are negative, WIT is <20 min, and no major complications)was used to evaluate the overall surgical effect. The DCOM, R. E.N.A.L. and PADUA scores were performed on all patients and compared with each other to evaluate the surgical effect of DCOM score in partial nephrectomy. Results:All surgeries in this study were successfully completed, including 141 partial nephrectomies and 43 radical nephrectomies. The DCOM score was 10(9, 11) for radical nephrectomy and 6(5, 8) for partial nephrectomy, and the difference was statistically significant ( P=0.001). There were 23 patients (37.7%) in highly complex group, 39 patients (88.6%) in moderately complex group and 79 patients (100.0%) in mildly complex group underwent partial nephrectomy, respectively. According to multifactorial analysis, patients in highly and moderately complex group of DCOM score had 8.88 times ( P=0.001) and 1.76 times ( P=0.005) less reach MIC than those in mildly complex group, respectively. Patients in highly and moderately complex group of PADUA score had 4.86 times ( P=0.005)and 3.41 times ( P=0.006)less reach MIC than patients in mildly complex group of DCOM score, respectively. What’s more, patients in moderately complex group of R. E.N.A.L. score had 3.11 times ( P=0.003) less reach MIC than patients in mildly complex group of DCOM score. In the ROC curves to predict MIC achievement, the AUC values of R. E.N.A.L., PADUA and DCOM scores were 0.657, 0.655 and 0.746, respectively. Comparing:R. E.N.A.L. score with DCOM score, the AUC value was statistically significant ( P=0.025). Conclusions The surgical difficulty scoring system (DCOM score) based on holographic imaging can predict the outcome of partial nephrectomy, but further verification is needed.

Objective Budd-Chiari syndrome is apt to be misdiagnosed,so we explore its diagnosis and treatment by liver transplantation.Methods We retrospectively analyzed the clinical data of two patients who underwent liver transplantation for Budd-Chiari syndrome.One patient was misdiagnosed before the transplantation and another was diagnosed correctly.Results Both patients were grouped to Child C category with decompensated liver cirrhosis.Patient 1 was diagnosed as recurrent hepatocellular carcinoma,but the etiology of liver disease was first unknown then suspected to be schistosomiasis.This patient underwent piggyback liver transplantation.Because there was significant swelling in the perineum and lower extremities after liver transplantation,we re-reviewed the preoperative imaging data and found communicant veins between hepatic veins,which proved that the patient was actually suffered from Budd-Chiari syndrome with hepatic vein and suprahepatic vena cava occlusion before the transplantation.After conservative treatment,the swelling of the lower body was alleviated,however,the long-term survival of the patient would be compromised.Learning from the first case,we found communicant veins between hepatic veins in imaging data of patient 2,resulting in correct diagnosis of Budd-Chiari syndrome with hepatic vein and retrohepatic vena cava diseases before the transplantation,so the patient underwent orthotopic liver transplantation,in which the liver and retrohepatic vena cava were resected,and recovered uneventfully.Liver function was normal during the follow up period of 7 months.Conclusion We should consider the possibility of Budd-Chiari syndrome in patients with unexplained end-stage liver diseases.Communicant veins between the hepatic veins shown in thin CT or MRI image are the characteristic sign for diagnosing Budd-Chiari syndrome.Simultaneously hepatic vein or cava vena disease determines the choice of various technique of liver transplantation.

Objective:To investigate the potential of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in mitigating the adverse prognosis associated with central nervous system leukemia (CNSL) and to assess the significance of prophylactic intrathecal injection.Methods:A retrospective cohort analysis was conducted involving 30 patients with acute leukemia who had a history of CNSL who underwent allo-HSCT at Peking University People′s Hospital between September 2012 and March 2018 (referred to as the CNSL-positive group). In addition, 90 patients with acute leukemia were selected from the same period who underwent allo-HSCT without a history of CNSL (referred to as the CNSL-negative group) and a rigorous 1∶3 matching was performed based on disease type, disease status, and transplantation type to form the control group. The prognosis between the two groups was compared using Kaplan-Meier analysis and the high-risk factors for CNSL relapse post-transplant were identified through Cox proportional-hazards model.Results:The median age of patients in the CNSL-negative group was significantly higher than that of patients in the CNSL-positive group (32 years vs. 24 years, P=0.014). No significant differences were observed in baseline data, including sex, disease type, disease status at transplantation, donor-recipient relationship, and human leukocyte antigen consistency between the two groups. The median follow-up time was 568 days (range: 21-1 852 days). The 4-year cumulative incidence of relapse (71.4%±20.9% vs. 29.3%±11.5%, P=0.005) and the cumulative incidence of CNSL post-transplant (33.6%±9.2% vs. 1.2%±1.2%, P<0.001) were significantly higher in the CNSL-positive group than in the CNSL-negative group. Furthermore, the 4-year leukemia-free survival rate in the CNSL-positive group was significantly lower than that in the CNSL-negative group (23.1%±17.0% vs. 71.5%±11.6%, P<0.001). However, no significant differences were observed in the 4-year cumulative transplant-related mortality and overall survival rates between the two groups (both P>0.05). Multivariate analysis revealed that a history of CNSL before transplantation ( HR=25.050, 95% CI 3.072-204.300, P=0.003) was identified as high-risk factors for CNSL relapse post-transplant. Conversely, haploidentical transplantation was associated with a reduced risk of CNSL relapse post-transplant ( HR=0.260, 95% CI 0.073-0.900, P=0.034). Within the CNSL-positive group, seven patients received prophylactic intrathecal therapy after transplantation, and their CNSL relapse rate was significantly lower than that of the 23 patients who did not receive intrathecal therapy after transplantation (0/7 vs. 9/23, P=0.048). Conclusions:Patients with a history of CNSL have a higher risk of relapse and experience poorer leukemia-free survival following transplantation. The use of prophylactic intrathecal injection shows promise in mitigating CNSL relapse rates, although further validation through prospective studies is necessary to substantiate these observations.
