Objective:To summarize the clinical outcomes of en-bloc kidney transplantation from small infant donors to adult recipients at a single center.Methods:A total of 22 en-bloc transplantations from pediatric donors to adult recipients were performed from July 2013 to October 2017 in Institute of Organ Transplantation Affiliated Tongji Hospital Tongji Medical College Huazhong University of Science. Clinical data were retrospectively analyzed. The average age of 22 donors was (2.9±1.7) months with an average weight of (4.9±1.4) kg and 15 of them were aged under 3 months. The average weight of 22 adult recipients was (46.3±5.6) kg and most recipients were female. The causes of early graft failure and recipient death were examined during follow-ups. The recipients with functioning grafts post-transplantation were divided into single kidney survival group and en-bloc kidney survival group based upon the occurrence of unilateral vascular thrombosis. Medium/long-term renal graft function was compared between two groups.Results:Early graft failure occurred in 4 recipients. The causes were bilateral renal vascular thrombosis ( n=2), renal rupture ( n=1) and multiple organ failure followed by death ( n=1). Eighteen recipients were discharged after a recovery of renal graft function. One case had a removal of bilateral renal grafts due to new-onset graft tumor and another two died from interstitial pneumonia and complicate systematic disorder respectively during follow-ups. Among the remaining 15 recipients, 10 achieved bilateral renal survival (median follow-up: 59 months) and 5 unilateral renal survival (median follow-up: 48 months). The average eGFR of bilateral renal survival group was significantly higher than that of unilateral renal survival group at Year 1 post-transplantation (95±27 vs 61±24 ml/min/1.73 m 2, P<0.05) while the gap narrowed at Year 3 and there was no statistical significance (95±21 vs 69±31 ml/min/1.73 m 2, P=0.12). Conclusions:Although en-bloc kidney transplantation from infant donors can expand organ donor pool, there is a higher risk of early graft failure and unilateral renal vascular thrombosis. Nevertheless, satisfactory renal transplant outcomes may be achieved in patients with unilateral renal graft survival.

BACKGROUND:The patients receiving total knee arthroplasty are high in average age, and often accompanied with hypertension, diabetes and other basic diseases. Due to the poor physical conditions of the patients,
perioperative hemorrhage becomes the important factor that affecting the safety of replacement.
OBJECTIVE:To analyze perioperative hidden hemorrhage of primary total knee arthroplasty, and to explore the method of evaluating perioperative blood loss by osteoarthritis severity before total knee arthroplasty.
METHODS:A retrospective analysis of 126 knee osteoarthritis patients undergoing total knee arthroplasty was conducted. Al the patients were divided into two groups according to Kel gren and Lawrecne imaging classification:stage Ⅲ group and stage Ⅳ group. The hidden hemorrhage of the patients in two groups was calculated.
RESULTS AND CONCLUSION:The average total blood loss of the patients was 1 560 mL, included hidden hemorrhage 865 mL (55%). The mean blood loss of stage Ⅲ group was 1 290 mL with the mean hidden
hemorrhage of 684 mL (53%). The mean blood loss of stage Ⅳ group was 1 644 mL with the mean hidden
hemorrhage of 921 mL (56%). Statistical analysis showed there were significant differences of total blood loss and hidden hemorrhage between two groups (P<0.05), but there was no significant difference in the percentage of
hidden hemorrhage. The results indicate that higher grade of osteoarthritis imaging classification, the more of total blood loss and hidden hemorrhage, while the change of the percentage of hidden hemorrhage is not significant. Preoperative evaluation of patients’ blood loss by osteoarthritis severity has great significance for blood
management and surgical safety of patients.

Objective To evallhte factors affecting blood loss during mini-percutaneous nephrolithotomy using ureteroscope and pneumatic intracorporeal lithotripsy(MPCNL). Methods 1156MPCNL procedures in 885 patients from July 2002 to October 2006 were reviewed. Various patientrelated and intraoperative factors were assessed for association with total blood loss using multivariate regression analysis. ResuIts The average hemoglobin drop was(14.2+8.3)g/L.The overall blood transfusion rate was 1.5%. Approximately 0.6%of patients required angiography embolization to control intractable bleeding. Multivariate regression analysis showed that the occurrence ot operative complications(6=0.496,P<0.001),size of the tract(b=0.405,P<0.001),mature nephrostomy tract(6=0.377,P<0.001),multiple tracts(6=0.326,P=0.005),size of stone(b=0.210,P=0.015),operative time(6=0.139,P=0.027),renal parenehymal thickness(b=0.128,P=0.035),prior stone intervention(b=-0.121,P=0.038),diabetes(b=0.110,P=0.051),and bacteriuria(b=-0.095,P=0.058)were significant predictors of blood loss.Factors such as age,sex,side,obesity,hypertension,renal function,operating surgeon,anaesthesia,calix of puncture,number of attempts to successful puncture,urine from puncture needle may not affect the blood loss. Concluslons Maneuvers that may reduce blood loss include reducing the operative time,decreasing the occurrence of intraoperative complications, reducing the tract size and tract number, and staging the procedure.Staging the procedure of MPCNL is a judicious decision in case of a large stone burden,intraoperative complications,multiple-tract,lager tract or diabetes.

In recent years, although the quantity of organ donation after citizen's death has been constantly increased, a large number of patients with end-stage renal diseases are waiting for kidney transplantation every year. The imbalance between donor and recipient is still one of the main problems affecting kidney transplantation in clinical practice. Therefore, it is of clinical significance to accurately evaluate the quality of donor kidney and fully utilize the expanded criteria donor kidney. Contrast-enhanced ultrasound has been gradually applied in the detection of multiple solid organs due to its safety, portability, real-time detection, quantification and other characteristics, and it also has promising application prospect in the evaluation of donor kidney quality. In this article, the advantages and limitations of current evaluation methods for donor kidney and current status and advantages of contrast-enhanced ultrasound in donor kidney evaluation were reviewed, and the application prospect of contrast-enhanced ultrasound in the evaluation of donor kidney quality was discussed, aiming to increase the methods and enhance the accuracy for donor kidney evaluation, and provide reference for rational use of expanded criteria donor kidney.

OBJECTIVE To build a standardized simulation teaching system for resident pharmacists and evaluate its effects, and to provide reference for improving the competency of resident pharmacists. METHODS The established simulation teaching system for pharmacy residents’ standardized training in the study included revising the simulation teaching syllabus, setting up simulation teaching courses, implementing the teaching method through “six types of simulations”, applying objective structured clinical examination (OSCE) for assessment, building a simulation teaching team and strengthening the simulation teaching management. The effect evaluation was perfermed with mixed research method, and qualitative and quantitative research methods were used to collect and analyze data and information. RESULTS &&CONCLUSIONS Compared with the traditional teaching system, the passing rate of graduation examination (71.4% vs. 100%) and the score of after-department examination ([ 76.2±7.8) vs. (90.4±4.9)] under the simulation teaching mode were higher; through questionnaire surveys and qualitative interviews, we found that resident pharmacists who went through simulation teaching gave positive feedback on the role and impact of this system. The simulation teaching system can be used with good generalizability for the standardized training of resident pharmacists, and can provide strong basis and support for the high-quality development of hospital pharmacy.

Objective:To explore the safety and feasibility of optimized pathological evaluation system of donor's kidney and modified surgery during adult dual kidney transplantation(DKT)and evaluate its effectiveness to provide more alternative protocols for kidney transplantation from extended criteria donors.Methods:DKT was performed in 10 recipients using the same protocol from June 2019 to May 2021.And retrospective reviewing was performed for clinical data, including characteristics of donors and recipients, optimized pathological evaluation system, modified surgery, treatment regimens, complications and follow-ups.Results:There were 8 male and 2 female donors with an age of(57.9±12.8)years and BMI(24.1±4.1)kg/m 2.The percentage of DCD was 70% and DBD 30%.The serum creatinine before procurement was 107.6(93.3-163.5)μmol/l.Zero-point puncture biopsy was performed for both kidneys and optimized pathological evaluation system was implemented(Banff criteria & Remuzzi score). The pathological results indicated that glomerular sclerosis for left and right kidneys were 2.0(1.5-2.0)and 1.5(1.0-2.0). And Remuzzi score for left and right kidneys were(4.4±1.2)and(3.6±1.5)points respectively.All recipients were male with an age of(43.1±9.0)years and BMI(22.2±1.9)kg/m 2.All PRAs were negative pre-operation.Modified surgery was performed in all recipients(two kidneys were implanted outside iliac vessels without patch and artery of superior kidney was anastomosed to internal iliac artery). Operative duration was(195±54.3)min and serum creatinine before discharge 125.0(102.0-199.0)μmol/L.Renal dynamic scintigraphy indicated that glomerular filtration rate was(30.0±8.2)ml/min for left kidney and(29.2±13.9)ml/min for right kidney.MRA results indicated that morphologies of renal arteries and veins were regular.The time between operation and discharge was(22.4±4.7)days.Compared with SKT, serum creatinine before discharge of DKT was lower and DGF incidence of DKT was higher without statistical significance.The time between operation and discharge was longer for DKT than that for SKT( P<0.05). The complications consisted of 20% donor derived infection(DDI)and 50% DGF.And there was no surgical complication associated with vessels and ureter.Renal function remained stable during 6-month follow-ups. Conclusions:Optimized pathological evaluation system of donor's kidney and modified surgery during adult dual kidney transplantation are both safe and feasible.The postoperative function of transplanted dual kidney is successfully restored.However, long-term follow-ups are required for evaluating its effectiveness.

Objective:To summarize the medium-term outcomes of single kidney transplantation from senile deceased donors aged above 65 years.Methods:Forty-three kidney recipients from donors aged above 65(old-aged donor group, OAD) and 43 kidney recipients of the same age and gender from donors aged 18 to 49 years(standard-criteria donor group, SCD) were retrospectively reviewed.The survival outcomes of patients and grafts, renal functions, the incidence of delayed graft function(DGF)and other complications were recorded within the 3-year follow-up post-transplantation.Results:The 3-year patient survival rates were 95.3% both in OAD and SCD and the 3-year death-censored graft survival rates 92.7% and 97.6% respectively.The serum levels of creatinine were significantly higher in OAD than that in SCD( P<0.05). And lower estimated glomerular filtration rate(eGFR)was found in OAD as compared with SCD( P<0.05). No significant difference existed in the incidence of DGF(OAD 20.9% and SCD 18.6%, P>0.05), acute rejection (OAD 4.7% and SCD 2.3%, P>0.05)or proteinuria(OAD 27.9%and SCD 14.0%, P>0.05). Conclusions:Single kidney transplantation from old-aged deceased donors may achieve excellent medium-term survival outcomes of patients and grafts.It can expand the donor pool though kidney functions were not as good as those of SCD.

Objective:To explore the outcome of kidney transplantation from donation after cadaveric death(DCD)with high pathological Remuzzi score.Methods:From January, 2019 to December, 2019, 31 recipients of kidney allograft transplantation from marginal donors with Remuzzi score≥4 in preimplantation biopsy were retrospectively enrolled. They were divided into two groups of dual kidney transplantation(DKT, 14 cases)and single kidney transplantation(SKT, 17 cases). Median Remuzzi score of left kidney(5.05 in DKT group vs 4.92 in SKT group)or right kidney(5.26 vs. 4.58)was comparable. Dual donor kidneys were implanted into ipsilateral iliac fossa. Survival outcomes, kidney function, acute rejection episodes, incidence of delayed graft function(DGF)and proteinuria were recorded within Year 1 post-operation.Results:Proportion of male(92.9% vs. 52.9%, P<0.05)and recipient's body mass index(BMI, 23.93 vs. 21.09)were significant higher in DKT group than those in SKT group. One graft failure occurred in DKT group at Month 11 post-operation. The 1-year graft survival rate was 92.9% in DKT group and 1-year recipient survival rate both 100% in two groups. Mean 12-month serum creatinine[SCr, (164±37.7)μmol/L vs. (154.92±96.2)μmol/L]and estimated glomerular filtration rate[eGFR, (41.84±9.01) vs. (44.8±18.16)ml/(min·1.73m 2)]were comparable between two groups(both P>0.05). There was no occurrence of thrombosis resulting in graft loss. One-year incidence of acute rejection, rate of DGF(42.9% vs 41.2%)and proteinuria(57.1% vs. 41.2%)were comparable between two groups(both P>0.05). Conclusions:Through donor-recipient matching and dual kidney transplant allocation, short-term survival outcome of kidney allograft from marginal donors with high Remuzzi score≥4 is encouraging. However, long-term outcomes should be further examined.
