BACKGROUND Despite the developments in the field of kidney transplantation,the already existing diagnostic techniques for patient monitoring are considered insufficient.Protein biomarkers that can be derived from modern approaches of proteomic analysis of liquid biopsies(serum,urine)represent a promising innovation in the monitoring of kidney transplant recipients.AIM To investigate the diagnostic utility of protein biomarkers derived from proteomics approaches in renal allograft assessment.METHODS A systematic review was conducted in accordance with PRISMA guidelines,based on research results from the PubMed and Scopus databases.The primary focus was on evaluating the role of biomarkers in the non-invasive diagnosis of transplant-related com-plications.Eligibility criteria included protein biomarkers and urine and blood samples,while exclusion criteria were language other than English and the use of low resolution and sensitivity methods.The selected research articles,were categorized based on the biological sample,condition and methodology and the significantly and reproducibly differentiated proteins were manually selected and extracted.Functional and network analysis of the selected proteins was performed.RESULTS In 17 included studies,58 proteins were studied,with the cytokine CXCL10 being the most investigated.Biological pathways related to immune response and fibrosis have shown to be enriched.Applications of biomarkers for the assessment of renal damage as well as the prediction of short-term and long-term function of the graft were reported.Overall,all studies have shown satisfactory diagnostic accuracy of proteins alone or in combination with conventional methods,as far as renal graft assessment is concerned.CONCLUSION Our review suggests that protein biomarkers,evaluated in specific biological fluids,can make a significant contribution to the timely,valid and non-invasive assessment of kidney graft. 展开更多

BACKGROUND Thumb replantation following complete traumatic avulsion requires complex techniques to restore function,especially in cases of avulsion at the level of the metacarpophalangeal joint(MCP I)and avulsion of the flexor pollicis longus(FPL)at the musculotendinous junction.Possible treatments include direct tendon suture or tendon transfer,most commonly from the ring finger.To optimize function and avoid donor finger complications,we performed thumb replantation with flexion restoration using brachioradialis(BR)tendon transfer with palmaris longus(PL)tendon graft.CASE SUMMARY A 20-year-old left-handed male was admitted for a complete traumatic left thumb amputation following an accident while sliding from the top of a handrail.The patient presented with skin and bone avulsion at the MCP I,avulsion of the FPL tendon at the musculotendinous junction(zone 5),avulsion of the extensor pollicis longus tendon(zone T3),and avulsion of the thumb’s collateral arteries and nerves.The patient was treated with two stage thumb repair.The first intervention consisted of thumb replantation with MCP I arthrodesis,resection of avulsed FPL tendon and implantation of a silicone tendon prosthesis.The second intervention consisted of PL tendon graft and BR tendon transfer.Follow-up at 10 months showed good outcomes with active interphalangeal flexion of 70°,grip strength of 45 kg,key pinch strength of 15 kg and two-point discrimination threshold of 4 mm.CONCLUSION Flexion restoration after complete thumb amputation with FPL avulsion at the musculotendinous junction can be achieved using BR tendon transfer with PL tendon graft. 展开更多

Diabetic foot ulcers(DFUs)represents a significant public health issue,with a rising global prevalence and severe potential complications including amputation.Traditional treatments often fall short due to various limitations such as high recurrence rates and extensive resource utilization.This editorial explores the innovative use of acellular fish skin grafts as a transformative approach in DFU management.Recent studies and a detailed case report highlight the efficacy of acellular fish skin grafts in accelerating wound closure,reducing dressing changes,and enhancing patient outcomes with a lower socio-economic burden.Despite their promise,challenges such as limited availability,patient acceptance,and the need for further research persist.Addressing these through more extensive randomized controlled trials and fostering a multidisciplinary treatment approach may optimize DFU care and reduce the global health burden associated with these complex wounds. 展开更多

Grafting is an effective technique for increasing the resistance of vegetables to biotic and abiotic stresses.It has been widely applied to produce solanaceous and melon vegetables.Temperature is an important external factor affecting graft formation.However,the molecular mechanism by which external ambient temperature affects tomato graft formation remains unclear.In this study,we demonstrated that elevating ambient temperature during grafting to 35℃ for more than 24 h after grafting accelerated vascular reconnection.We generated self-or heterografted combinations between phyB1B2 and pif4 loss-of-function mutant and wild-type plants,and were mutants unresponsive to graft formation at elevated ambient temperature.In addition,elevated ambient temperature induced SlPIF4 expression during grafting.SlPIF4 directly binds the promoters of auxin biosynthesis genes SlYUCCAs and activates their expression.Further investigation revealed auxin accumulation in the graft junction under elevated ambient temperature.The results illuminate the mechanism by which the PHYB-PIF4-auxin module promotes tomato graft formation in response to elevated ambient temperature. 展开更多

Dear Editor,Liver transplantation(LT)is the only curative therapy for patients with endstage liver disease(He et al.,2023;Ling et al.,2022).Post-transplant hypertriglyceridemia(PTHT),which has an incidence of up to 32.8%in 6 months after LT,is one of the major post-transplant complications(Toshima et al.,2020).With the prolongation of the recipient’s survival time,the incidence of PTHT is increasing,becoming an important factor that affects the recipient’s quality of life and survival time.Recipients with various metabolic complications,including PTHT,have a 1.78 times higher risk of atherosclerotic cardiovascular disease(ASCVD)development and death than recipients without these complications(Jiménez Pérez et al.,2016).Studies have shown that PTHT,accompanied by other posttransplant metabolic complications and immunosuppressants,are important risk factors for post-transplant ASCVD and mediate 19%–42% of nongraft-related deaths(Davis and Shadab Siddiqui,2017;Jiménez-Pérez et al.,2016).However,early prediction of PTHT remains a major challenge. 展开更多

BACKGROUND Inferior vena cava(IVC)leiomyosarcomas are rare and aggressive tumors.Complete cure depends on achieving R0 resection,which often requires circumferential resection and reconstruction.Synthetic grafts have traditionally been used when venous continuity must be restored.However,the use of cadaveric IVC grafts for reconstruction has not been widely reported.CASE SUMMARY Herein,we present the case of a 64-year-old woman diagnosed with an intrahepatic IVC leiomyosarcoma with local invasion.The patient responded favorably to chemotherapy and subsequently underwent an en bloc right hepatectomy,retrohepatic IVC resection,and reconstruction with an interpositional cadaveric IVC graft.Serial imaging follow-ups until 2 years after the operation showed persistent patency of the graft and no graft-related complications.CONCLUSION Cadaveric IVC grafts are an alternative to synthetic grafts for reconstruction,with acceptable outcomes.Larger,long-term studies are necessary to validate these findings. 展开更多

BACKGROUND Meniscus extrusion occurs in most elderly individuals and most patients after meniscus allograft transplantation.The risk factors and correlative factors of meniscus extrusion have been extensively studied.However,for using tendon autograft for meniscus reconstruction,both graft type and surgical method are different from those in previous studies on meniscus extrusion.AIM To identify predictive factors for coronal and sagittal graft extrusion length after using tendon autograft for medial meniscus reconstruction.METHODS Ten patients who underwent medial meniscus reconstruction with tendon autograft were selected for this retrospective observational study.The graft extrusions and potential factors were measured and correlation and regression analyses were performed to analyze their relationships.RESULTS The medial graft extrusion correlated with the preoperative bilateral hip-kneeankle angle difference,preoperative Kellgren-Lawrence grade,preoperative relative joint space width,and preoperative bilateral medial edge incline angle difference.The anterior graft correlated with the anterior tunnel edge distance at 1 week after operation.The posterior graft extrusion correlated with the preoperative bilateral hip-knee-ankle angle difference,preoperative relative joint space width,and posterior tunnel edge distance at 1 week after operation.The mean graft extrusion correlated with the preoperative bilateral hip-knee-ankle angle difference and preoperative relative joint space width.The preoperative joint space width and anterior and posterior tunnel edge distance at 1 week can be used to predict the medial,anterior,posterior,and mean graft extrusion length.CONCLUSION The preoperative joint space width and tunnel position can be used to predict the coronal and sagittal graft extrusion length after using tendon autograft for medial meniscus reconstruction. 展开更多

Objective:Peyronie’s disease(PD)is an abnormal wound healing in the penile tunica albuginea.After fibrotic plaque excision,different graft materials have been used to repair the defects,but the optimal graft remains unknown.This study aimed to compare the functional outcomes of testicular tunica vaginalis grafts and bovine pericardium grafts in patients with severe PD.Methods:A retrospective comparative study was conducted on 33 PD patients undergoing partial plaque excision and grafting from September 2015 to May 2021.The patients were divided into two groups depending on the type of graft used.For 15 patients in Group B,testicular tunica vaginalis grafts were used to repair the defect,while for 18 patients in Group A,bovine pericardium grafts were used.Data of the patient’s age,comorbidities,sexual function,penile curvature,postoperative complications,need for further treatment,change in penile length,and satisfaction were gathered and compared between the groups.Sexual function was evaluated using the 5-item version of the International Index of Erectile Function(IIEF-5),and a functional less than 20-degree penile curvature after surgery was considered a successful intervention.Results:There was no difference in age,comorbidities,degree of curvature,perioperative IIEF-5,operative time,plaque size,or complication rates.After surgery,a statistically significant improvement in curvature degree(p<0.05)and satisfactory penile appearance(p<0.05)were seen in both groups without any superiority between the two groups(p=0.423 and p=0.840,respectively).With a 30-month follow-up,the IIEF-5 was consistent in both groups,with no statistical significance between the groups(p=0.492).The main change in penile length during the operation was increased and still positive in the last follow-up in both groups without statistical significance(p=0.255 and p=0.101,respectively).Conclusion:Partial plaque excision and corporoplasty with both testicular tunica vaginalis or bovine pericardium grafts are equally effective in treating males with clinically significant PD. 展开更多

This letter addresses the recent study by Zhu et al on the predictive factors for coronal and sagittal graft extrusion length following medial meniscus reconstruction using tendon autografts.The study provides valuable insights into the importance of preoperative joint space width and tunnel positioning as predictors of graft extrusion.Specifically,it found strong correlations between preoperative joint space width and medial,posterior,and mean graft extrusion at both 1 week and 8 months post-operation.Additionally,tunnel edge distance at 1 week postoperation correlated with anterior and posterior graft extrusion.These findings offer critical guidance for improving surgical outcomes.However,the letter highlights the need for further research with larger sample sizes and comparative studies involving different graft types to strengthen these findings and broaden their applicability in clinical settings.The study's contributions to understanding meniscus reconstruction using tendon autografts are acknowledged,along with suggestions for future research directions. 展开更多

BACKGROUND Liver grafts from donation after circulatory death(DCD)are associated with a higher risk of early graft dysfunction,determined by the warm ischemia and cold ischemia times.It is essential to have precise criteria to identify this complication in order to guide therapeutic strategies.AIM To validate different graft and recipient survival scores in patients undergoing liver transplantation(LT)with DCD grafts.METHODS A retrospective and observational unicentric study was conducted on 65 LT patients with grafts obtained from controlled DCD donors from November 2013 to November 2022.The United Kingdom(UK)risk score,early allograft dysfunction(EAD)Olthoff score,and model for early allograft function(MEAF)score were used to evaluate the risk of graft and recipient survival post-transplant.For survival analysis purposes,we used the Kaplan-Meier method,and the differences between subgroups were compared using the log-rank(Mantel-Cox)test.RESULTS Sixty-five patients were included in the study.The UK risk score did not demonstrate predictive capacity for recipient or graft survival.However,in donors aged over 70 years old(18.4%),it significantly predicted graft survival(P<0.05).According to Kaplan-Meier survival curves,graft survival rates at 6 months,2 years,and 5 years in the futility group dramatically decreased to 50%compared to the other groups(log-rank 8.806,P<0.05).The EAD Olthoff and MEAF scores did not demonstrate predictive capacity for recipient or graft survival.Based on Kaplan-Meier survival curves,patients with a MEAF score≥7 had a lower graft survival rate at 6 months,2 years,and 5 years compared to patients with a lower MEAF score(log-rank 4.667,P<0.05).CONCLUSION In our series,both UK DCD risk score and MEAF score showed predictive capability for graft survival. 展开更多

BACKGROUND The study focuses on the use of multi-parametric ultrasound[gray scale,color Doppler and shear wave elastography(SWE)]to differentiate stable renal allografts from acute graft dysfunction and to assess time-dependent changes in parenchymal stiffness,thereby assessing its use as an efficient monitoring tool for ongoing graft dysfunction.To date,biopsy is the gold standard for evaluation of acute graft dysfunction.However,because it is invasive,it carries certain risks and cannot be used for follow-up monitoring.SWE is a non-invasive imaging modality that identifies higher parenchymal stiffness values in cases of acute graft dysfunction compared to stable grafts.AIM To assess renal allograft parenchymal stiffness by SWE and to correlate its findings with functional status of the graft kidney.METHODS This prospective observational study included 71 renal allograft recipients.Multi-parametric ultrasound was performed on all patients,and biopsies were performed in cases of acute graft dysfunction.The study was performed for a period of 2 years at Sanjay Gandhi Postgraduate Institute of Medical Sciences,Lucknow,a tertiary care center in north India.Independent samples t-test was used to compare the means between two independent groups.Paired-samples t-test was used to test the change in mean value between baseline and follow-up obser-vations.RESULTS Thirty-one patients had experienced acute graft dysfunction at least once,followed by recovery,but none of them had a history of chronic renal allograft injury.Mean baseline parenchymal stiffness in stable grafts and acute graft dysfunction were 30.21+2.03 kPa(3.17+0.11 m/s)and 31.07+2.88 kPa(3.22+0.15 m/s),respectively;however,these differences were not statistically significant(P=0.305 and 0.252,respectively).There was a gradual decrease in SWE values during the first 3 postoperative months,followed by an increase in SWE values up to one-year post-transplantation.Patients with biopsy-confirmed graft dysfunction showed higher SWE values compared to those with a negative biopsy.However,receiver operating characteristic analysis failed to show statistically significant cut-off values to differentiate between the stable graft and acute graft dysfunction.CONCLUSION Acute graft dysfunction displays higher parenchymal stiffness values compared to stable grafts.Therefore,SWE may be useful in monitoring the functional status of allografts to predict any ongoing dysfunction. 展开更多

Budding is an important grafting technique to asexually propagate pecan(Carya illinoinensis(Wangenh.)K.Koch).To determine factors that might hamper success-ful budding of the species,a representative easy-to-survive cultivar‘Pawnee’and a typical difficult-to-survive culti-var‘Jinhua’were used for comprehensive analysis.Mor-phological observation showed that cells surrounding the secretory cells or sieve tube had collapsed in‘Jinhua’but not in‘Pawnee’during grafting.‘Jinhua’might suffer more hypoxia stress than‘Pawnee’as‘Jinhua’had higher catalase,superoxide dismutase,polyphenol oxidase,pyruvate decar-boxylase(PDC),alcohol dehydrogenase(ADH)activities during grafting and contained greater levels of hydrogen per-oxide 12 days after grafting(DAG).Transcriptions of PDC and ADH were also up-regulated significantly in‘Jinhua’whereas they were not significantly affected in‘Pawnee’.Phenylalanine ammonia-lyase activities of‘Jinhua’were consistently lower than that of‘Pawnee’.Initial phenol con-tents were similar between the two cultivars.Graft-promot-ing substances,including soluble sugar,soluble protein,and gibberellin(GA)were incompletely recovered in‘Jinhua’12 DAG while fully restored in‘Pawnee’.Increased levels of trans-zeatin riboside in‘Jinhua’were much smaller than in‘Pawnee’3 DAG.The contents of indole-3-acetic acid were similar,and the dynamics of abscisic acid were the same between the two genotypes.Results suggest that hypoxia stress and shortages of sugar,protein,GA,and cytokinin during the healing process might be key factors limiting successful budding of pecan.The degree of scion-rootstock compatibility and the content of phenols might be excluded as constraints for successful budding. 展开更多

Humic acids(HAs)are widely used as filtrate and viscosity reducers in drilling fluids.However,their practical utility is limited due to poor stability in salt resistance and high-temperature resistance.Hightemperature coal pitch(CP)is a by-product from coal pyrolysis above 650℃.The substance's molecular structure is characterized by a dense arrangement of aromatic hydrocarbon and alkyl substituents.This unique structure gives it unique chemical properties and excellent drilling performance,surpassing traditional humic acids in drilling operations.Potassium humate is prepared from CP(CP-HA-K)by thermal catalysis.A new type of high-quality humic acid temperature-resistant viscosity-reducer(Graft CP-HA-K polymer)is synthesized with CP-HA-K,hydrolyzed polyacrylonitrile sodium salt(Na-HPAN),urea,formaldehyde,phenol and acrylamide(AAM)as raw materials.The experimental results demonstrate that the most favorable conditions for the catalytic preparation of CP-HA-K are 1 wt%catalyst dosage,30 wt%KOH dosage,a reaction temperature of 250℃,and a reaction time of 2 h,resulting in a maximum yield of CP-HA-K of 39.58%.The temperature resistance of the Graft CP-HA-K polymer is measured to be 177.39℃,which is 55.39℃ higher than that of commercial HA-K.This is due to the abundant presence of amide,hydroxyl,and amine functional groups in the Graft CP-HA-K polymer,which increase the length of the carbon chains,enhance the electrostatic repulsion on the surface of solid particles.After being aged to 120℃ for a specified duration,the Graft CP-HA-K polymer demonstrates significantly higher viscosity reduction(42.12%)compared to commercial HA-K(C-HA-K).Furthermore,the Graft CP-HA-K polymer can tolerate a high salt concentration of 8000 mg.L-1,measured after the addition of optimum amount of 3 wt%Graft CP-HA-K polymer.The action mechanism of Graft CP-HA-K polymer on high-temperature drilling fluid is that the Graft CP-HA-K polymer can increase the repulsive force between solid particles and disrupt bentonite's reticulation structure.Overall,this research provides novelty insights into the synthesis of artificial humic acid materials and the development of temperature-resistant viscosity reducers,offering a new avenue for the utilization of CP resources. 展开更多

To the Editor:Liver transplantation(LT)is the most effective method for endstage liver disease.Split liver transplantation(SLT)is an effective method to enlarge the number of liver grafts.However,because of the existence of portal vein variations,right hemi-grafts splitting and recipients’portal vein(PV)reconstruction might be more challenging[1,2].According to the origins of intrahepatic PV branches,Nakamura and his coworkers[3]classified PV variants into five classes(Fig.S1):type A to E.It is reported that the standard anatomy in PV branching pattern accounts for only 65%of investigated population,and that the most common anatomic variation of main portal vein(MPV)is trifurcation variation followed by right posterior portal vein(RpPV)as a first branch of MPV[4].Type C and D variations are the two most technique highly demanding types.The variation of PV in donated liver graft still challenges surgeons,especially in the field of SLT.There is still a lack of a common sense about the modality of complicated variations in PV reconstruction.Here,we presented two complicated SLT cases,existence of type C and D PV variations in grafts,respectively. 展开更多

Objective:Secondary pyeloplasty for recurrent ureteropelvic junction obstructions may be a safe and feasible surgical option for patients.This study aimed to demonstrate outcomes of utilizing a non-transecting buccal mucosa graft ureteroplasty for management of recurrent ureteropelvic junction obstruction after prior failed pyeloplasty.Methods:We performed a retrospective review of our Collaborative of Reconstructive Robotic Ureteral Surgery database for all consecutive patients who underwent buccal mucosa graft ureteroplasty between April 2012 and June 2022 for management of recurrent ureteropelvic junction obstructions after prior failed pyeloplasty.The primary outcome included surgical success which was defined as the absence of flank pain and no obstruction on imaging.Results:Overall,ten patients were included in our analysis.The median stricture length was 2.5(interquartile range[IQR]1.8-4.0)cm.The median operative time was 230.5(IQR 199.5-287.0)min and median estimated blood loss was 50.0(IQR 28.8-102.5)mL.At a median follow-up of 10.3(IQR 6.2-14.8)months,80%of patients were surgically successful and there were no major(ClavieneDindo Grade>2)complications.Conclusion:Buccal mucosa graft ureteroplasty is a valuable non-transecting surgical option for patients with recurrent ureteropelvic junction obstructions who failed prior pyeloplasty and has comparable outcomes to the literature regarding standard transecting techniques. 展开更多

Root regeneration is an important factor influencing the healing rate of graft union and the survival of double-root-cutting grafting.To date,little information is available on how to enhance root regeneration of rootstock in grafted watermelon(Citrullus lanatus)seedlings.In this study,the effects of different light treatments on root regeneration were determined.This revealed that addition of far-red light(Fr)could significantly expedite root formation in the rootstock.Moreover,the results of transcriptome analysis revealed that plant hormone pathway and auxinrelated genes were greatly induced by Fr,especially for auxin-response proteins(including CmIAA11,CmIAA17,and CmAUX28),Small auxinup RNA genes(including CmSAUR20 and CmSAUR50)and the auxin efflux transporter(CmPIN3).In addition,the expression of Phytochrome Interacting Factor(PIFs),such as CmPIF1,CmPIF3 and CmPIF7,was remarkably increased by Fr.These genes may act together to activate auxinrelated pathways under Fr treatment.Based on the results of HPLC-MS/MS analysis,the concentrations of different auxin-types in adventitious root were significantly influenced by Fr.Furthermore,the better growth of rootstock root displayed superior vasculature transport activity of the graft union with Fr treatment,which was determined by the acid magenta dyeing experiment.Therefore,all the results suggested that Fr could induce AR formation in rootstocks,which may be associated with the auxin accumulation by regulating the transcriptional level of auxinrelated and PIF genes.The findings of this study demonstrated a practicable way to shorten the healing period of graftings and improve the quality of grafted watermelon seedlings,which will provide a theoretical basis for the speeding development of industrialized seedlings production. 展开更多

This paper presents a superhydrophobic melamine(ME)sponge(ME-g-PLMA)prepared via high-energy radiation-induced in situ covalent grafting of long-alkyl-chain dodecyl methacrylate(LMA)onto an ME sponge for efficient oil–water separation.The obtained ME-g-PLMA sponge had an excellent pore structure with superhydrophobic(water contact angle of 154°)and superoleophilic properties.It can absorb various types of oils up to 66–168 times its mass.The ME-g-PLMA sponge can continuously separate oil slicks in water by connecting a pump or separating oil underwater with a gravity-driven device.In addition,it maintained its highly hydrophobic properties even after long-term immersion in different corrosive solutions and repeated oil adsorption.The modified ME-g-PLMA sponge exhibited excellent separation properties and potential for oil spill cleanup. 展开更多
