ABSTRACT
Objective:To explore the morbidity features and therapeutic outcomes of rejections in pediatric kidney transplantation (KT) recipients.Methods:Between January 2013 and June 2022, 360 children undergoing KT were recruited.The relevant clinical data were collected for examining the morbidity features and therapeutic outcomes of rejections.The serum levels of creatinine were compared among groups by non-parametric rank test.And Kaplan-Meier and Log-rank methods were employed for examining the incidence of rejection and comparing mortality-censored graft survival rates among patients with different times of rejection.Results:A total of 58 recipients had 82 incidents of rejection with a cumulative incidence of 6.3%, 9.2% and 11.3% at 3/6/12 months respectively.Among 50 incidents of biopsy-proved rejections, the types were T cell-mediated rejection [TCMR, 42.0%(21/50)], antibody-mediated rejection [20.0%(10/50), ABMR] and mixed rejection [38.0%(19/50)].Among 58 incidents of initial rejection, 69% had maintained graft function (MGF) and 31% impaired graft function (IGF) after anti-rejection regimens.Among 80.8%, 85.7% and 75% of recipients with clinical rejection, ABMR or borderline rejection while 36.4% in TCMR patients had MGF.Fifteen kidney allografts lost function in 58 recipients with rejection.Five-year death-censored graft survival was significantly lower in patients with two or more incidents of rejection (30.5%, 95% CI: 12.3%-75.4%) than in those without rejection (92.9%, 95% CI: 89.3%-96.6%) ( P<0.000 1) or with only one rejection (82.9%, 95% CI: 65.9%-100%)( P<0.001). Conclusions:The rejection rate remains high in KT children and it affects graft survival.And TCMR is more likely to cause impaired graft function.Recurrent rejections have a more pronounced impact upon graft survival.
ABSTRACT
Objective:To explore the diagnosis and treatment of transplanted renal artery stenosis(TRAS)in children.Methods:From January 2016 to August 2021, clinical data of 7 TRAS patients were collected.A definite diagnosis was confirmed by Doppler ultrasound and computed tomography angiography.Results:Patient age was significantly higher than donor age(11.9±3.7 vs 1.0±0.5 years, P<0.001); 5 patients had a widened diameter at stenotic grafted renal artery after intervention(1.98±0.47 vs 4.64±1.19 mm, P=0.002). A reduction in peak systolic flow velocity in stenotic segment of artery(463.3±90.6 vs 183.6±58.9 cm/s, P<0.001)and lower systolic blood pressure(137.2±15.5 vs 129.7±12.3 mmHg, P=0.029)were observed.Resistance index rose(0.38±0.22 vs 0.60±0.03, P=0.063). Significant difference of estimated glomerular filtration rate was observed at Week 4 post-operation as compared with pre-intervention.Two patients developed complications after intervention, including perirenal hematoma and stent-attached thrombus.Two patients were treated conservatively with a gradual increase in blood pressure and three antihypertensive drugs prescribed. Conclusions:Doppler ultrasound should be performed regularly after renal transplantation for detecting TRAS at an early stage in children.Interventional treatment is ideal for severe TRAS to improve perfusion and renal function.Clinicians should pay more attention to complications.
ABSTRACT
Objective:To summarize the strategies, influencing factors and evaluation methods of foreign stroke service system integration, so as to provide reference for the construction of integrated stroke service system in China.Methods:The scoping review method was used to search, screen and analyze the literature. Using search terms such as stroke and integration, a total of 7 527 articles from PubMed and other databases from 2000 to 2021 were obtained. The strategies, influencing factors, evaluation methods and results of stroke service system integration were extracted from the literature. The rainbow model of health integration was used to establish the literature analysis framework.Results:A total of 103 articles involved system integration strategies were included in the analysis, 49 articles involved integration influencing factors, and 32 articles involved integration evaluation. Stroke service system integration strategies included 3 categories and 13 forms, including service coverage, normative shaping and information technology integration. The influencing factors of integration included local stroke service resources, implementation ability, social development level and institutional environment. System integration evaluation included systematic evaluation and case evaluation.Conclusions:The goal of stroke service system integration is to improve the coverage, quality and efficiency of stroke services. The internal drive comes from market and technology. The three types of integration strategies have their own emphasis and are integrated with each other. They are deeply embedded in the regional resource, institutional and cultural environment. Their evaluation is facing the challenge of high situational and low universality.
ABSTRACT
Up to 60% of children with nephrotic syndrome may occur secondary adrenal insufficiency, and even adrenal crisis.Adrenal crisis is one of the serious complications of nephrotic syndrome in children.The mortality rate is high and it seriously threatens the life.Adrenal crisis is often lack of specific manifestations, and usually begin with gastrointestinal symptoms, accompanied by circulatory dehydration, neuropsychiatric symptoms, hyponatremia, hyperkalemia and hypoglycemia.Glucocorticoid replacement therapy is important.Active prevention can reduce the incidence of crisis and improve prognosis.
ABSTRACT
Objective:To explore the clinical characteristics of chronic kidney disease (CKD) at the stage 3-5D in children with renal anemia, and provide reference data for standardized diagnosis and treatment.Methods:A single-center retrospective study was conducted to collect clinical data in children with CKD at Beijing Children's Hospital Affiliated to Capital Medical University from January 2016 to December 2018. The patients were divided into CKD stage 3 group, stage 4 group and stage 5 group according to estimated glomerular filtration rate. The indexes of anemia among the groups were compared. Data on anemia indicators, treatment, and anemia improvement in maintenance dialysis children at stage 5D were analyzed.Results:A total of 171 children with CKD were included in the study. The hemoglobin levels in CKD stage 3 group, stage 4 group and stage 5 group were (126.4±20.5) g/L, (90.8±26.0) g/L and (78.7±18.4) g/L, respectively, and there was a statistical difference among the groups ( χ2=61.982, P<0.001; trend test F=71.061, P<0.001). The incidences of anemia in children with CKD stage 3, stage 4 and stage 5 were 27.3% (9/33), 83.3% (25/30) and 95.4% (105/108), respectively. Mild, moderate and severe anemia in children with CKD stage 3 accounted for 15.2%(5/33), 12.1% (4/33) and 0(0), respectively. Mild, moderate and severe anemia in children with CKD stage 4 accounted for 26.7% (8/30), 50.0% (15/30) and 6.7% (2/30), respectively. Mild, moderate and severe anemia in children with CKD stage 5 accounted for 21.3%(23/108), 60.2%(65/108) and 15.8%(17/108), respectively. Anemia type was mostly normocytic anemia. The hemoglobin of 30 children with CKD stage 5D at the initial stage of dialysis was (79.3±16.3) g/L. Twenty-three children with CKD stage 5D received erythropoietin combined with oral iron or intravenous iron therapy. The hemoglobin compliance rates in children with maintenance dialysis in initial phase, 1 month, 2 months and 3 months were 6.7% (2/30), 16.7%(5/30), 63.3%(19/30) and 90.0%(27/30), respectively. The correction time for anemia was (2.5±1.0) months. Twelve children with CKD stage 5D received iron sucrose infusion, and no adverse reaction occurred. Conclusions:Renal anemia has a high incidence in children with CKD. Early and standardized treatment is of great significance to improve outcome of renal anemia. Venous iron infusion is a safe and effective treatment method for children with maintenance dialysis.
ABSTRACT
Objective:To explore the application value of modified technique of ureter implantation in murine renal transplantation.Methods:Thirty left donor kidneys from BALB/c mice was transplanted into syngeneic mice. Cuff technique was applied for anastomosing kidney artery and vein. The procedure of ureter-bladder anastomoses shifted from implication-fixation-embedding to fixation-implication-embedding. Operative duration, recipient survival rate and complications were recorded.Results:Time for separating vessels, perfusion and excision of donor graft was (25±3) min, (10±6) s for warm ischemia and (25±5) min for cold ischemia. Time for separating recipient vessels was (12±5) min, (7±1) min for arterial anastomosis, (7±1) min for venous anastomosis, (13±2) min for ureter-bladder anastomosis, (5±1) min for right kidney excision and (5±1) min for abdominal closure. Operative duration was(77±3)min. Twenty-six recipients survived over 3 months. The successful operative rate was 86.7%.Conclusions:With a shorter learning curve, modified technique of ureter implantation is easier and faster so as to reduce the postoperative incidence of urinary tract complications during murine renal transplantation.

Conclusions:In the center, the major cause of CKD stage 2 to 5 in children was CAKUT, but the proportion of CAKUT and glomerular diseases was similar in CKD stage 5.The most common complication of CKD in children is anemia.Hypertension, anemia, SHPT and CVD increased with the progression of CKD staging.SHPT usually occurs in children with CKD stage 4 and 5.The incidence of complications in children with CKD caused by different factors is different.Hemodialysis is the main method of initial renal replacement therapy in the center.
ABSTRACT
Objective:To observe the clinical effect of children's massage combined with traditional Chinese medicine hot compress in the treatment of children with night crying heart and spleen fever syndrome.Methods:From April 2017 to January 2019, 90 children with nocturnal crying heart and spleen fever syndrome in the Department of Pediatrics, Shijiazhuang Traditional Chinese Medicine Hospital, who met the selection criteria were divided into 2 groups according to random numbers, with 45 cases in each group. The control group was given oral calcium and vitamin D, and the observation group was given children's massage combined with traditional Chinese medicine hot compress treatment. Both groups were treated for 7 days. The scores of TCM syndromes were performed before and after treatment, and the improved SPIEGEL sleep scale was used to evaluate the sleep quality of the children, and to evaluate the efficacy of crying and TCM syndromes.Results:After treatment, the scores of the primary and secondary symptoms in the observation group were significantly lower than those in the control group ( t values were 44.449, 46.204, 56.476, respectively, all Ps<0.001); SPIEGEL sleep scale score (4.7 ± 0.9 vs. 8.3 ± 1.4, t=14.715) was significantly lower than that of the control group ( P<0.01). While the tongue coating and fingerprint abnormalities did not change significantly after treatment in both groups ( χ2 values were 0.403, 0.401, respectively, all Ps>0.05). The total effective rate of crying in the observation group was 91.1% (41/45) and that in the control group was 62.2% (28/45). The difference between the two groups was statistically significant ( χ2=10.497, P<0.01). The total effective rate of TCM syndromes in the observation group was 97.8% (44/45) and the control group was 48.9% (22/45). The difference between the two groups was statistically significant ( χ2=27.500, P<0.01). Conclusions:Pediatric massage therapy combined with traditional Chinese medicine hot pack can improve the TCM syndromes and symptoms of children with night crying heart and spleen fever syndrome, relieve sleep dysfunction, and improve clinical efficacy.
ABSTRACT
Objective:To explore the diagnosis and treatment of focal segmental glomerulosclerosis (FSGS) post-kidney transplantation in children.Methods:Clinical data were retrospectively analyzed for 6 FSGS children after transplantation from 2015 to 2019. Massive proteinuria (3.2-13 g/24 h) occurred at 4 days-49 days post-transplantation. For proteinuria, glucocorticoid plus therapeutic plasma exchange and/or rituximab were provided with supplemental ACEI/ARB drugs. Five cases received tacrolimus as maintenance therapy while another case had cyclosporin A as an initial intensive therapy and switched to tacrolimus.Results:Four cases achieved complete remission after therapy. One recipient showed partial remission. During a follow up period of 11 months to 4 years, serum creatinine remained normal and stable in five cases while one died from severe pulmonary infection.Conclusions:Once FSGS occurs post-transplantation, prompt treatment of pulse glucocorticoid plus therapeutic plasma exchange and/or rituximab with supplemental ACEI/ARB drugs may yield favorable outcomes.
ABSTRACT
Objective:To explore the clinical characteristics and outcomes of pediatric kidney transplantations at a single center and discuss the related clinical issues.Methods:From January 1990 to October 2019, clinical data were analyzed retrospectively for 244 pediatric renal transplants. The youngest recipient was aged 1.8 years and the median age of pediatric recipients was 12.2 years. The major disease was primary or hereditary glomerulonephritis ( n=160, 69.0%), congenital anomalies of kidney and urinary tract (CAKUT), cystic renopathy and other hereditary nephropathies ( n=55, 23.7%). The donor sources included traditional deceased donor ( n=42, 17.2%), living-related donor ( n=19, 7.8%) and organ donation ( n=183, 75.0%). The median age of donors was 2 years (0-51) and the median weight 12.0(2.7-72.0) kg. From January 2013 to October 2019, 170 cases), the major induction immunosuppression regimen was anti-thymocyte globulin (ATG) ( n=110, 64.7%) or basiliximab ( n=58, 34.1%). The maintenance regimen was tacrolimus + mycophenolic acid (MPA) + glucocorticosteroids. Finally the outcomes and the complications were analyzed. Results:The survival rates of 244 kidney allograft recipients were 98.1%, 94.5% and 93.4% and the graft survival rates 92.6%, 84.2% and 82.0% at 1/3/5 years respectively. Ten recipients died of accident ( n=2, 20.0%), pneumonia after transplantation ( n=2, 20.0%) and intracranial hemorrhage ( n=2, 20.0%). Thirty-three recipients lost their allografts mainly due to intravascular thrombosis in graft ( n=5, 14.3%), acute rejection ( n=5, 14.3%) and death ( n=9, 25.7%). Besides, among 109 deceased donor allograft recipients, the postoperative outcomes were delayed graft function recovery (DGF) ( n=27, 24.8%), arterial thrombosis ( n=6, 5.5%), venous thrombosis ( n=1, 0.9%), graft perirenal hematoma ( n=6, 5.5%), raft artery stenosis ( n=10, 9.2%) and graft ureteral fistula ( n=1, 0.9%). The incidence of acute rejection was 17.5% and 23.2% at 1/3 year respectively. The recurrent rate of primary disease was 6.9%, including primary FSGS ( n=3, 42.9%) and IgA nephropathy ( n=2, 28.6%). At 1/3 year post-operation, the incidence of pulmonary infection was 16.9% and 22.4% and the incidence of urinary tract infection 26.9% and 31.7%. Excluding recipients with graft failure, the estimated glomerular filtration rate (eGFR) at 1/2/3 year postoperatively was (80.3±25.2), (81.4±27.8) and (71.8±27.6) ml/(min·1.73 m 2)respectively. Conclusions:The outcomes of pediatric renal transplantations are excellent at our center. Future efforts shall be devoted to optimizing the strategies of donor kidney selection and strengthening preoperative evaluations, perioperative and postoperative managements for improving the long-term outcomes of pediatric renal transplantations.
ABSTRACT
OBJECTIVE@#To study the clinical features of catch-up growth of body height after kidney transplantation in children and related influencing factors.@*METHODS@#A retrospective analysis was performed from the chart review data of 15 children who underwent kidney transplantation in Guangzhou Women and Children's Medical Center from July 2017 to November 2019. According to whether the increase in height standard deviation score (ΔHtSDS) in the first year after kidney transplantation reached ≥0.5, the children were divided into a catch-up group with 8 children and a non-catch-up group with 7 children. According to whether final HtSDS was ≥-2, the children were divided into a standard group with 6 children and a non-standard group with 9 children. The features of catch-up growth of body height and related influencing factors were compared between groups.@*RESULTS@#The data showed that median ΔHtSDS was 0.8 in the first year after transplantation, which suggested catch-up growth of body height. There was a significant difference in HtSDS between the non-catch-up and catch-up groups (P<0.05). Baseline HtSDS before transplantation was positively correlated with HtSDS at the end of follow-up (r=0.622, P<0.05) and was negatively correlated with ∆HtSDS in the first year after transplantation (r=-0.705, P<0.05). Age of transplantation and mean dose of glucocorticoid (GC) per kg body weight were risk factors for catch-up growth after kidney transplantation (OR=1.23 and 1.74 respectively; P<0.05), while baseline HtSDS and use of antihypertensive drugs were independent protective factors for catch-up growth (OR=0.08 and 0.18 respectively; P<0.05); baseline HtSDS and ΔHtSDS in the first year after kidney transplantation were influencing factors for final HtSDS (β=0.984 and 1.271 respectively; P<0.05).@*CONCLUSIONS@#Kidney transplantation should be performed for children as early as possible, growth retardation before transplantation should be improved as far as possible, and multiple treatment methods (including the use of GC and antihypertensive drugs) should be optimized after surgery, in order to help these children achieve an ideal body height.

Objective@#To analyze the epidemiological characteristics, trend and related factors of tuberculosis patients that delayed for care, in Wuhan from 2008 to 2017.@*Methods@#Data regarding tuberculosis (TB) patients was collected from the tuberculosis management information system (TMIS), a part of the China information system for disease control and prevention from 2008 to 2017. A total of 64 208 tuberculosis patients, aged 0 to 95 years were included for the analysis. Unconditional logistic regression method was used to estimate those factors that associated with this study.@*Results@#Days of delay among TB patients appeared as M=10 (P25-P75: 3-28) day, in Wuhan, 2008-2017. The prevalence of the delay was 52.5% (33 703/64 208), presenting a downward trend from 2008 to 2017 (trend χ2=10.64, P<0.001), but the proportions of women and ≥65 year-olds were gradually increasing. Results from the multivariate logistic regression analysis showed that factors as: patients living far away from the city vs. near the city (OR=1.29, 95%CI: 1.25-1.35), and age above 45 years vs. younger than 25 years (the age 45-64 years group vs. aged less than 25 years group, OR=1.22, 95%CI: 1.15-1.29; the age 65 or above group vs. aged less than 25 years group, the OR=1.30, 95%CI: 1.22-1.39) were under higher risk on the delay of seeking care. Occupation, way of case-finding and classification of tuberculosis patients also appeared as influencing factors on this issue.@*Conclusions@#Prevalence on the delay of care was 52.5% among tuberculosis patients in Wuhan, 2008-2017, but with an annual decrease. Attention should be paid to female, wrinkly or elderly tuberculosis patients regarding the delay of care on TB, in Wuhan.
ABSTRACT
Objective To investigate the effects of form deprivation on the morphology of different types of RGC in mice.Methods Sixty B6.Cg-Tg (Thy1-YFP) HJrs/J transgenic mice were randomly assigned to form-deprived group (n=28) and control group (n=32). The right eyes of mice in the form-deprived group were covered by an occluder for 2 weeks as experimental eyes. The right eyes of mice in the control group were taken as control eyes. Before and 2 weeks after form deprivation, the refraction and ocular biometrics were measured; RGC were stained with Bra3a antibody and counted; the morphology of RGC was reconstructed with Neuroexplore software after immunohistochemical staining. The data was compared among experimental eyes, fellow eyes and control eyes by one-way analysis of variance.Results Two weeks after form deprivation, the axial myopia was observed in the experimental eyes (refraction:F=15.009,P<0.001; vitreous chamber depth:F=3.360,P=0047; ocluar axial length:F=5.011,P=0013). The number of RGC in central retina of the experimental eyes was decreased compared with the fellow eyes and the control eyes (F=4.769,P=0.035). The reconstructed RGC were classified into 4 types according to their dendritic morphology. Form deprivation affected all 4 types of RGC but in a different way. Among them, 3 types of RGC were likely contribute to form vision perception. Form deprivation increased the dendrite branches in these types of ganglion cells. However, form deprivation decreasd dendrite segment numbers in both eyes and the intersection and length insholl analyse type 4 ganglion cells which were morphologically identified as ipRGC.Conclusion Form deprivation distinguishingly affects the morphology of different types of RGC, indicating that form vision and non-form vision play different role in myopia development.

Totally 960 high-risk infants, who accepted type B ultrasonic examination for fetus at 28th week of gestation and for newborns in 48 hours after birth, were included in the study in departments of obstetrics and eonatology, Shunyi Maternal and Children's Hospital of Beijing Children's Hospital during May 2012 to April 2013. The degree of pyelectasis was classified using Grignon grade and the paients were followed up for 3 years. The factors of epidemiology, high risk pregnant women, fetus and high-risk newborns that relate to pyelectasis were summarized. High-risk factors were analyzed by using logistic multivariate regression analysis.@*Results@#Of 960 high-risk infants, 103 had abnormal urinary ultrasound results, 87 (9.1% of high-risk infants) were diagnosed with pyelectasis, 16 (1.7% of high-risk infants) were diagnosed with congenital anomalies of the kidney and urinary tract. According to the degree of pyelectasis, 68 infants were Grignon grade Ⅰ, male:female ratio=5.8∶1, left side:right side ratio=1.91∶1; 19 infants were Grignon grade Ⅱ, male:female ratio=5.33∶1, left side:right side ratio=2.12∶1. Postnatal follow-up results showed that pyelectasis disappeared in 48 cases (55% of pyelectasis cae), 40 infants were Grignon grade Ⅰ (59% of all Grignon grade Ⅰ patients), 8 infants were Grignon grade Ⅱ (42% of all Grignon grade Ⅱ patients); The result of risk factors analysis showed that the risk of pyelectasis in males was 4.368 times that of females (95%CI: 2.33-8.189, P<0.05); the risk of pyelectasis in low birth weight infants was 22.434 times that of non low birth weight infants (95% CI: 5.883-85.547, P<0.05).@*Conclusion@#The incidence of pyelectasis in high-risk infants was 9.1%. The mitigation rate of pyelectasis in Grignon grade Ⅰ to Ⅱ in fetal or newborn period is high. Patients in Grignon grade Ⅲ and above in fetal or new born period had high risk of congenital anomalies of the kidney and urinary tract. The risk of pyelectasis of male was higher than that of female; the risk of pyelectasis of low birth weight infant was higher than appropriate for gestational age infants.
ABSTRACT
Objective To explore the clinical outcome of renal transplantation and analyze the risk factors influencing the kidney allograft survival after transplantation.Methods The clinical data of 524 cases of renal transplantation between January 2007 and December 2015 were retrospectively analyzed.Serum creatinine was determined,and glomerular filtration rate(GFR) was estimated.The 1-,2-and 3-year patient and graft survival after transplantation was calculated.Adverse events were recorded.Results The median follow-up time was 17.2 months.The 1-,2-and 3-year graft survival rate after transplantation was 97％,95.8％ and 95.3％,respectively.The 1-,2-and 3-year patient survival rate after transplantation was 97.8％,97％ and 97％,respectively.The eGFR was (67.6 ± 24.1),(68.9±24.2) and (72.7 ± 26.2) ml·min-1 ·1.73 m-2 at 1st,2nd and 3rd year after transplantation.The incidence of delayed graft function(DGF) was 20.6％ (108/524).Multivariate analysis revealed donor type (P =0.005) and the terminal creatinine (P＜0.001) were the independent risk factors of DGF.Elder recipients (P =0.004),recipients with diabetes(P =0.031),preoperative positivity of panel reactive antibody(PRA) (P =0.023),and donor with hypertension (P =0.046) were risk factors influencing the kidney allograft survival.Conclusion Kidney transplantation showed good outcomes at 3rd year after transplantation.The recipient age,recipient's history of diabetes,preoperative PRA and donor's history of hypertension are independent risk factors for renal graft survival.
