OBJECTIVE: To investigate the effect of relaxing needling at the contracted sites of meridian-muscle regions in the patients with post-stroke shoulder-hand syndrome (SHS) at acute stage. METHODS: Eighty patients with post-stroke SHS at acute stage were randomized into an observation group (40 cases, 1 case dropped out) and a control group (40 cases, 1 case was eliminated). In the control group, the routine medication, basic rehabilitation training, and hyperbaric oxygen therapy were administered. In the observation group, besides the treatment as the control group, relaxing needling was delivered at the contracted sites of meridian-muscle regions. These contracted sites were distributed along three yin meridians of hand and three yang meridians of hand on the affected upper limbs. The intervention was given once daily, 5 times a week and for 4 weeks. Before and after treatment, the scores of visual analogue scale (VAS) for pain, edema degree, modified Barthel index (MBI), and Fugl-Meyer assessment (FMA) for motor function, and the integrated electromyography (iEMG) of surface electromyogram (sEMG) were observed in the two groups. The curative effect was evaluated after treatment and in follow-up of 2 months after treatment in the two groups. RESULTS: After treatment, VAS scores and the scores of edema degree were reduced when compared with those before treatment in the two groups (P<0.05), and the scores in the observation group were lower than those in the control group (P<0.05). MBI and FMA scores increased after treatment compared with those before treatment in the two groups (P<0.05), and the scores in the observation group were higher than those in the control group (P<0.05) after treatment. The iEMG values of the biceps brachii, triceps brachii, and wrist extensors were elevated after treatment in comparison with those before treatment (P<0.05) in the two groups, and the values in the observation group were larger than those in the control group after treatment (P<0.05). The total clinical effective rate in the observation group was 92.3% (36/39), which was better than that of the control group (74.4%, 29/39, P<0.05) after treatment; and that of the observation group was 97.4% (38/39), which was better than 82.1% (32/39) in the control group (P<0.05) in follow-up. CONCLUSION Relaxing needling at the contracted sites of meridian-muscle regions in treatment of post-stroke SHS at acute stage can attenuate the symptoms such as upper limb pain, swelling and spasm, improve motor function and the activity of daily living of patients.

Naringenin (4,5,7-trihydroxyflavonoid) is a naturally occurring bioflavonoid found in citrus fruits, which plays an important role in metabolic syndrome, neurological disorders, and cardiovascular diseases. However, the pharmacological mechanism and biological function of naringenin on anti-angiogenesis and anti-tumor immunity have not yet been elucidated. Our study firstly demonstrates that naringenin inhibits the growth of hepatocellular carcinoma (HCC) cells both in vivo and in vitro. Naringenin diminishes the ability of HCC cells to induce tube formation and migration of human umbilical vein endothelial cells (HUVECs) and suppresses neovascularization in chicken chorioallantoic membrane (CAM) assays. Meanwhile, in vivo results demonstrate that naringenin can significantly upregulate level of CD8⁺ T cells, subsequently increasing the level of immune-related cytokines in the tumor immune microenvironment. Mechanistically, we found that naringenin facilitate the K48-linked ubiquitination and subsequent protein degradation of vascular endothelial growth factor A (VEGFA) and mesenchymal-epithelial transition factor (c-Met), which reduces the expression of programmed death ligand 1 (PD-L1). Importantly, combination therapy naringenin with PD-L1 antibody or bevacizumab provided better therapeutic effects in liver cancer. Our study reveals that naringenin can effectively inhibit angiogenesis and anti-tumor immunity in liver cancer by degradation of VEGFA and c-Met in a K48-linked ubiquitination manner. This work enlightens the potential effect of naringenin as a promising therapeutic strategy against anti-angiogenesis and anti-tumor immunity in HCC.

This report described one human leukocyte antigen pre-sensitized recipient undergoing preoperative plasmapheresis (PP), intravenous immunoglobulins (IVIG) desensitization and immune induction therapy before kidney transplantation with a donor kidney. Early postoperative clinical diagnosis was acute antibody-mediated rejection (AMR). A marked elevation of donor-specific antibodies (DSA) was accompanied by a decline of renal function. PP/IVIG dosing failed to lower the level of DSA. After low-dose splenic irradiation, DSA level dropped steadily and transplanted kidney function normalized. Thus adjuvant low-dose splenic irradiation may eliminate DSA immediately without a rebound.

Objective:To explore the efficacy and safety of daratumumab in late antibody-mediated rejection (late AMR) after kidney transplantation (KT).Methods:From December 2020 to December 2021, the relevant clinical data were reviewed for 8 patients with late AMR after receiving daratumumab at Affiliated Tongji Hospital. In intensive phase, the combination of plasma exchange (PP)/intravenous immunoglobulin (IVIG) and daratumumab were dosed once a week; in maintenance phase, once every 2 to 4 weeks. The levels of donor-specific antibody (DSA) and renal function were compared pre-treatment and Month 3/12 post-treatment. The treatment-related toxicities were observed. Independent sample T test was utilized for inter-group comparison.Results:The median treatment course during intensive period was 9(4-17) sessions. Maintenance treatment lasted for 5 to 19 months and 2 cases withdrew after 5 to 6 treatments for achieving antibody clearance. A total of 11 DSAs were detected in 8 recipients. At Month 3/12, mean fluorescent intensity (MFI) of DSA was 6 016±4 775 and 6 438±3 668. Both were significantly lower than 11 944±5 237 pre-treatment and the difference was statistically significant ( P=0.012, 0.004). Seven recipients achieved stable renal function during treatment and one recipient resumed hemodialysis at Month 18 due to acute rejection. Glomerular filtration rate of 7 recipients was (40.6±20.1), (53.6±20.9) and (49.0±17.2) ml·min -1· (1.73 m 2) -1 pre-treatment and Month 3/12 and no significant differences existed among different timepoints. During follow-ups, 2 cases developed mild nasal congestion during an early stage of daratumumab infusion while the remainders had no obvious discomfort during infusion and tolerance was decent. Conclusion:Early combination of daratumumab with PP/IVIG, followed by a course of daratumumab has demonstrated an excellent antibody reduction effect on late AMR. During treatment, renal function remains generally stable.

Objective To summarize the occurrence of complications in renal graft biopsy,and to analyze the indications for puncture and types of pathological diagnosis.Methods The data of 703 samples of ultrasound-guided renal graft biopsy from 644 kidney transplant recipients from January 1,2017,to December 31,2022 was retrospectively analyzed.The puncture qualification rate,complications,indicative biopsy indications and pathological diagnosis types were analyzed.The application of surveillance biopsy and pathological diagnosis were also analyzed.Results The qualification rate of renal tissue puncture biopsy was 99.9％,and the complications of puncture bleeding included one sample of perinephric hematoma and one sample of hematuria.Increased serum creatinine(76.8％)and proteinuria(13.8％)were the main indications for puncture,and 48 samples(6.8％)were surveillance biopsy for the assessment of therapeutic effects.A total of 399 samples of pathological diagnosis of rejection,including 293 samples of cellular rejection reaction,60 samples of antibody rejection reaction,and 46 samples of mixed rejection reaction.One hundred and ninety-five samples of recurrence or new-onset kidney disease,mainly including 144 samples of IgA nephropathy and 42 samples of focal segmental glomerulosclerosis.Fifty-seven samples of infection related kidney disease,including 56 samples of BK virus-associated nephropathy(BKVAN).Thirty-one samples of calcineurin inhibitor(CN1)nephrotoxicity injury,including 15 samples of acute CNI nephrotoxicity injury and 16 samples of chronic CNI nephrotoxicity injury.Forty-five samples for other diagnoses.Conclusions The success rate and safety of renal graft biopsy are high,and at present,cellular rejection reaction is still the main pathological diagnosis of indicative biopsy for renal graft.

Objective:To summarize the incidence of acute rejection (AR) after pediatric kidney transplantation (KT) at a single center and examine its impact on graft/patient survival and risk factors for AR.Methods:This is a retrospective cohort study including pediatric recipients who underwent kidney transplantation in past 8 years.After excluding recipients of graft thrombosis within a week post-transplant and lost to follow-ups, a total of 143 cases were ultimately recruited and assigned into two groups of AR (n=29) and non-AR (n=114).Basic profiles of both donors and recipients and graft/patient survival rate were compared between two groups.Relative risk factors for AR episodes were also examined by Logistic regression.Results:Renal grafts for 130/143 cases (90.9%) were harvested from deceased donors and 120(83.9%) cases from children.Twenty-seven transplants (18.9%) were performed in infants and young recipients aged < 3 years.During a median follow-up of 33 months, 34 AR episodes occurred in 29(20.3%) patients.Rate of re-transplantation (27.6% vs. 7.9%), pediatric donor (96.5% vs. 80.7%) and rabbit anti-human thymocyte globulin (rATG) induction (79.3% vs. 36%) were significantly higher in AR group than non-AR group ( P=0.007, P=0.046, P<0.001).Multivariate regression analysis indicated that basiliximab induction caused a significant reduction in the risk of AR incidence as compared with rATG induction (odds ratio 0.13, 95% confidence interval 0.04-0.43, P<0.001).The median time of AR incidence was 1.3 months post-transplantation and 23 episodes (67.6%) were confirmed by biopsy.After anti-rejection treatment, 52.9%(n=18) of the cases achieved a full recovery and 38.3% (n=13) had improved graft function.However, 3 cases (8.8%) developed irreversible graft failure.The 1/3-year graft survival rates were significantly lower in AR group than those in non-AR group (75.3% vs. 95.2%, 68.4% vs. 90.4%, P=0.01), and there was no significant difference in 1-and 3-year patient survival rates between two groups. Conclusions:The incidence of AR is relatively high in pediatric renal transplantation, which has an impact on graft survival.Basiliximab induction can effectively reduce the risk of AR.

Objective:To explore the clinical features of transplanted renal artery stenosis after pediatric donor kidneys in children.Methods:We retrospectively summarized the clinical data in five cases of transplanted renal artery stenosis undergoing deceased pediatric donor kidney transplantation from May 1, 2014 to June 30, 2021.Donor/receptor characteristics, diagnosis, treatment and prognosis were recorded.The median follow-up period was 29 months.The median age of five donors and recipients was 9 and 132 months respectively.En bloc renal allograft( n=2)and single kidney transplantation( n=3)were performed.End-to-side anastomosis was performed for renal arteries.The median diagnostic time of renal artery stenosis was 10(3-60)months post-transplantation.Except for one 3-year-old recipient with an earlier onset of stenosis, four stenotic cases during a rapid growth period had a maximal height increase of 30 cm post-transplantation.Three of them had a history of surgery at graft site, including previous kidney transplantation( n=1)and transplant urinary tract reconstruction( n=2). All five cases had hypertension and two showed an elevated serum level of creatinine.Ultrasound indicated a significantly elevated flow rate of >300 cm/s( n=4)and CTA/MRA indicated that the degrees of stenosis varied from 50% to 95%( n=5). Results:After balloon dilatation, stenosis either improved( n=2)or relapsed( n=2). Further stenting succeed( n=1)or failed( n=1). One case of stenosis was relieved partially after 6-month observation without any invasive treatment. Conclusions:As a serious complication, transplant renal artery stenosis is common after pediatric donor kidney transplantation.Too small size in donor kidney and rapid recipient growth may be specific risk factors.After diagnosis, balloon dilation is a preferred treatment.Stent placement should be cautiously employed.

Objective:To summarize the clinical characteristics and treatment of cytomegalovirus(CMV)infection in pediatric kidney transplant patients.Methods:From May 2014 to July 2021, a total of 9 cases(8.65%)of 104 pediatric kidney transplant recipients were diagnosed with CMV infection in our centre.Retrospective data was collected for these 9 paediatric recipients.The clinical characteristics of the disease, treatment data and outcomes were summarized.Results:The median age of the 9 children was 10 years(0.25-15 years), 6 of whom were treated with polyclonal antibody for immunity induction.CMV IgG was negative in 4 children before renal transplantation.Only one patient received anti-CMV prophylaxis.The median time from transplant to the diagnosis of CMV infection was 22(7-15)days.Among the 9 children, 7 had fever, pneumonia and diarrhea, 2 had no typical symptoms, three patients were complicated with viral, bacterial or fungal infections.Acute rejection occurred in 3 patients at the same time as CMV infection or after CMV DNA turned negative.Nine patients were cured and discharged after ganciclovir or valganciclovir treatment.Median time of CMV DNA negative transformation was 32(17-90)days.Conclusions:Pediatric transplant recipients are at particularly elevated risk of CMV disease.Antiviral prophylaxis should be initiated early after transplantation.
