Objective:To explore the impact of early and late antibody-mediated rejection (AMR) on treatment options and allograft outcomes after kidney transplantation (KT).Methods:From January 2013 to December 2022, the study retrospectively enrolled 141 KT allograft recipients receiving allograft biopsy and diagnosed as AMR according to the Banff 2019 criteria. Recipients with a diagnosis of AMR within 30 days post-KT were classified into early AMR group (n=19) while the remainders assigned as late AMR group (n=122). The outcome endpoints included recipient survival rate, death-censored graft survival rate, follow-up estimated glomerular filtration rate (eGFR) and immunodominant donor-specific antibody (DSA) intensity. Wilcoxon's test was utilized for assessing the differences in eGFR and DSA intensity while Kaplan-Meier curve and Log-rank test were employed for evaluating graft survival impact. Treatment regimens for AMR were collected and categorized.Results:The median follow-up duration was 2.6(1.2, 5.2) year. No graft failure was noted in early AMR group while 44 recipients in late AMR group experienced graft failure, with 34 cases (77.2%) due to AMR progression. The 5-year death-censored graft survival rate was significantly better in early AMR group than that in late AMR group [100% vs 60.1%(50.5%, 71.6%), P=0.002]. The one-year change in eGFR for early AMR group was significantly superior to that of late AMR group [19.3(-2.6, 38.1) vs -3.3(-14.0, 5.4), P=0.001]. One-year mean fluorescent intensity (MFI) of early AMR group was 1 158(401.5, 3 126.5). It was significantly lower than that when diagnosed with early AMR [3 120.5(2 392.8, 9 340.0)] and one-year MFI of late AMR group [8 094(2 251.5, 13 560.5)] ( P=0.005, P<0.001). Early AMR group primarily received standard treatment (3/19, 15.8%) and regimens centered on rituximab and/or bortezomib (7/19, 43.8%). Late AMR group mainly received standard (16/122, 13.1%) or intensified regimens (9/122, 7.4%) and regimens focused upon rituximab and/or bortezomib (32/122, 26.2%) and MP monotherapy (21/122, 17.2%). Conclusion:The outcome for early AMR is significantly better than that for late AMR. For early AMR, early and robust immunosuppression is recommended. For late AMR, early detection and timely treatment are crucial and individualized strategies should be implemented.

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.

There are many kinds of variabilities of fetal venous system tending to complicated with complex cardiovascular malformations.Prenatal ultrasound is of great importance for evaluation of fetal venous system.High-definition flow(HD-Flow)combined with spatiotemporal image correlation(STIC)could not only display micro blood flow in fetal venous system,but also show the spatial alignment and flow direction in real time.The research progresses of HD-Flow combined with STIC for evaluating fetal venous system abnormalities were reviewed in this article.

Objective:To explore the therapeutic mechanism of Mongolian medicine Sendeng-4 decoction for rheumatoid arthritis by 99Tc m-hydrazinonicotinamide-(polyethylene glycol) 4-E[(polyethylene glycol) 4-c((Arg-Gly-Asp)fk)] 2 (3PRGD 2) imaging. Methods:A total of 200 female SD rats (age: 6-7 weeks) were divided into collagen-induced arthritis (CIA) group ( n=176) and blank control group ( n=24). Rats in the CIA group were divided into Sendeng-4 decoction treatment group ( n=24), etanercept treatment group ( n=24), and negative control group ( n=24) by simple random sampling method. 99Tc m-3PRGD 2 SPECT/CT imaging was performed before and after modeling and treatment. The differences of target/non-target (T/NT) ratio and serological, pathological, and immunohistochemical results among groups were compared by one-way analysis of variance or Kruskal-Wallis rank sum test. The correlation was analyzed by Pearson correlation or Spearman correlation analysis. Results:There were 95 (95/176) CIA models successfully established. The T/NT ratios of Sendeng-4 decoction treatment group and etanercept treatment group were lower than that of negative control group (0.260± 0.094, 0.238±0.099, 0.766±0.144 ; F=163.00, P<0.001), while there was no significant difference between the two drug treatment groups ( P>0.05). After drug treatment, serum levels of vascular endothelial growth factor (VEGF), tumor necrosis factor-α (TNF-α) and α vβ 3 were significantly lower than those of negative control group ( F values: 49.43-92.36, all P<0.001), pathological score was also lower than that of negative control group ( H=34.25, P<0.001), and levels of immunohistochemical makers (VEGF, TNF-α, α vβ 3, CD31, CD34) were also lower than those of negative control group ( H values: 13.51-26.84, all P<0.001), while there were no significant differences between the two drug treatment groups (all P>0.05). The T/NT ratios were positively correlated with above indictors in Sendeng-4 decoction treatment group ( r values: 0.56-0.59, rs values: 0.49-0.69), etanercept treatment group ( r values: 0.50-0.55, rs values: 0.46-0.70) and negative control group ( r values: 0.55-0.80, rs values: 0.58-0.86, P<0.001 or P<0.05). Conclusion:Verified by 99Tc m-3PRGD 2 SPECT/CT imaging and molecular pathology, Mongolian medicine Sendeng-4 decoction can inhibit neovascularization by down-regulating vascular factors such as VEGF, resulting in delaying the progression of the disease and improving clinical symptoms.

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.

Objective:To investigate the clinical value of peripheral monocyte and neutrophil count in predicting the response of patients with metastatic non-small cell lung cancer (mNSCLC) to immunosuppressive checkpoint inhibitors (ICI).Methods:The clinical data of 34 adult mNSCLC patients who received nafulizumab or pabolizumab in Danzhou People's Hospital of Hainan Province from January 2017 to March 2019 were retrospectively analyzed. The correlation of the demographic characteristics, clinical data, hematological examination results in the first two weeks before the treatment and two weeks after ICI treatment with prognosis was recorded and observed.Results:The baseline mean monocyte count [(0.52±0.09)×10 9/L vs. (0.60±0.12)×10 9/L] and neutrophil count [(4.27±0.87)×10 9/L vs.(5.39±1.02)×10 9/L] of patients with ICI reaction were lower than those of patients without ICI reaction, and the differences were statistically different ( t = -2.572, -2.727, all P < 0.05). However, there was a negative correlation between the monocyte count of the patients who responded to ICI and the reaction time ( r = -0.507, P < 0.05). The median reaction time in patients with monocyte count >0.70×10 9/L was shorter than that in patients with monocyte count ≤0.70×10 9/L (8 weeks vs. 12 weeks, χ2=4.162, P = 0.041). There was no correlation between monocyte count and time of reaction duration, progression of free survival (PFS) and overall survival (OS) ( r = -0.214, 0.182, 0.232, all P > 0.05). The decrease rate of neutrophil count in response group was higher than that in non-response group (22% vs. 2%, P < 0.05). After the first administration, cutoff value of neutrophil count was 4.2×10 9/L; the response rate of patients with neutrophil count ≤ 4.2×10 9/L was higher than that of patients with neutrophil count > 4.2×10 9/L [86.7% (13/15) vs. 36.8% (7/19), χ2=6.657, P < 0.05]. Conclusion:Peripheral blood monocyte and neutrophil count can predict the response to ICI therapy in patients with mNSCLC.
