RESUMEN
Objective: This study explicitly demonstrates the roles of natural killer (NK) cells in different types of kidney transplantation. Methods: We'd done the whole study from October 2022 to October 2023. To further explore the significance of NK cells during renal transplantation, we provide a theoretical basis for clinically overcoming immune rejection after renal transplantation by developing new anti-rejection drugs. We selected twelve male mice and divided them into three groups (Syngeneic transplant group allograft transplant group allograft transplant (priming) group) by random. Initially, the morphological and histopathological changes in the kidney transplantation graft model of mice in different groups are observed. Further, the DSA-IgG levels in peripheral blood and C3d and IgG deposition in mice are detected by ELISA and immunohistochemical staining. Then, the Banff 2015 score is recorded to screen a suitable AMR mouse model. Finally, the expression of NK cells in different rejection modes is detected by flow cytometry, and the expressions of various cytokines (INF-γ, perforin, granzyme B, TNF-α) in peripheral blood are detected by enzyme-linked immunosorbent assay (ELISA). Results: In the allogeneic transplantation (priming) group, peritubular capillary inflammatory cell infiltration, moderate endarteritis, and small arterial fibrinoid necrosis are evident. The Banff score showed that the allogeneic transplantation (pre-sensitized) group is significantly higher than the syngeneic and allogeneic transplantation groups. The C3HâC57BL/6 mice are pre-sensitized by skin transplantation, and then kidney transplantation is performed to establish the antibody-mediated rejection (AMR) model. After kidney transplantation, the expression levels of NK cells in the peripheral blood, spleen, and transplanted kidney tissue of mice in the pre-sensitized group are significantly higher than in the allogeneic transplantation and control groups. In the C3HâC57BL/6 mouse model of AMR, NK cells and the related cytokines in the peripheral blood are highly expressed after kidney transplantation, proving that NK cells play an essential role in the occurrence of AMR. Conclusion: Our study proved the significance of NK cells in the occurrence of AMR by systematically monitoring the expression of NK cell-related cytokines in different types, which provided some ideas for the clinical treatment of AMR.
RESUMEN
Whether neoadjuvant therapy confers a survival benefit in advanced prostate cancer (PCa) remains uncertain. The primary endpoints of previous retrospective and phase II clinical studies that used neoadjuvant therapy, including androgen deprivation therapy combined with new-generation androgen receptor signaling inhibitors or chemotherapy, were pathological downstaging, progression-free survival, prostate-specific antigen relief, and local symptom improvement. To the best of our knowledge, no studies have explored the efficacy and safety of neoadjuvant therapy in improving the surgical resection rate in cases of unresectable primary tumors of PCa. We first designed this retrospective study to evaluate the potential value of apalutamide as neoadjuvant therapy in improving the resectability rate of radical prostatectomy (RP). We initially reported 7 patients with unresectable primary lesions who underwent neoadjuvant apalutamide treatment for a median of 4 months, and all of them successfully underwent RP treatment. Our study supported apalutamide as neoadjuvant therapy, which helped improve RP's success rate and did not significantly increase perioperative complications, and the neoadjuvant therapy was controllable. Our findings' clinical value and benefit for survival still need further clinical research to confirm.
RESUMEN
Renal vein thrombosis (RVT) is a rare vascular complication that occurs after renal transplantation and usually results in irreversible kidney damage and graft loss. We report the case of a patient who underwent right iliac fossa allogeneic kidney transplantation and developed RVT combined with ipsilateral thrombosis from the popliteal to the femoral veins, with extension to the common iliac veins, 4 months after transplantation. Under unfractionated heparin anticoagulation, an Aegisy (Life Tech Scientific Co., Ltd., Shenzhen, China) vena cava filter was placed to prevent pulmonary embolism. Percutaneous mechanical thrombectomy combined with balloon angioplasty was performed to aspirate the thrombus and successfully dilate the narrow venous lumen. The patient's renal function was restored postoperatively. Ultrasonography showed the allograft and ipsilateral lower extremity deep veins to be fluent and patent. To conclude, in patients with RVT after renal transplantation, percutaneous mechanical thrombectomy in conjunction with balloon angioplasty can be performed with desirable outcomes and no severe adverse effects. This method reduces the risk of bleeding from exposure to systemic intravenous thrombolysis and avoids surgery-associated trauma.

INTRODUCTION: Limited data from China, aim to investigate the incidence and the risk fctors of lymph node metastases in the prostatic anterior fat pad (PAFP). MATERIAL AND METHODS: Patients underwent radical prostatectomy (RP) were enrolled between March 2020 to December 2022 at a single institution. Separate pathological analysis of PAFP was performed within this area. Univariate analysis and Multivariate analysis were performed to determine the risk factor of PAFP metastasis. RESULT: A total of 255 patients were included. The study revealed an average age of 67.72 ± 7.07 years, with a mean total tumor volume of 41.54 ± 23.79 mL, and an average Pre-op PSA of 16.85 ng/mL. Clinical T stage was divided into T2, T3, and T4 (226, 25, 4 cases, respectively), while the Clinical M stage was categorized as M0 and M1 (248 and 7 cases, respectively). Out of the patients with PAFP, 19 (7.45 %) had lymph node in PAFP, and 3 (1.18 %) patients had metastases. In the univariate and multivariate analysis, Clinical M stage and anterior primary tumor were found to be a significant high-risk factor. Among the other 15 studies, six examined the risk factors associated with it, including anterior tumors, higher tumour volume, intermediate or high risk prostate cancer. CONCLUSION: Due to the low proportion of lymph node involvement (7.45 %) and rare tumor metastasis (1.18 %), routine separate pathological analysis of PAFP is not recommended in all RP patients unless there are anterior tumors, higher tumor volume, or intermediate/high risk prostate cancer.

Porcine reproductive and respiratory syndrome virus (PRRSV) infection causes severe interstitial pneumonia and inflammatory response in piglets and growing pigs. IL-1ß is implicated in PRRSV-mediated inflammatory response and the pathogenesis of PRRSV infection. Mitochondria are critical intracellular organelles which is served as signaling platform for antiviral immunity response to participate in immune response of virus infection. The role of mitochondria in PRRSV-mediated inflammatory response and the pathogenesis of PRRSV infection has not been elucidated. Here, our data suggested that PRRSV infection facilitates mitochondrial dysfunction, which induces cytosolic mitochondrial DNA (mtDNA) stress and ROS accumulation, severally activates the NLRP3 inflammasome and NF-κB signaling pathway, and consequently stimulates IL-1ß production in PAMs. Furthermore, mtDNA degradation by DNase I abrogates the activation of NLRP3 inflammasome and IL-1ß secretion during PRRSV infection. Scavenging ROS significantly inhibits NF-κB signaling activation and the subsequently transcription and secretion of IL-1ß. In conclusion, our results indicate that cytosolic mtDNA stress and ROS accumulation after PRRSV infection-induced mitochondrial dysfunction activate NLRP3 inflammasome and NF-κB signaling pathway to promote IL-1ß production, revealing a new strategy for vaccine and drug development to PRRSV.

Various genome editing tools have been developed for programmable genome manipulation at specified genomic loci. However, it is crucial to comprehensively interrogate the off-target effect induced by these genome editing tools, especially when apply them onto the therapeutic applications. Here, we outlined the off-target effect that has been observed for various genome editing tools. We also reviewed detection methods to determine or evaluate the off-target editing, and we have discussed their advantages and limitations. Additionally, we have summarized current RNA editing tools for RNA therapy and medicine that may serve as alternative approaches for genome editing tools in both research and clinical applications.

Background: Ductal carcinoma of the prostate (DCP) is a rare type of prostate cancer (PCa) with a higher degree of infiltration and worse prognosis than acinar adenocarcinoma of the prostate (ACP). Previous reports comparing DCP and ACP have not been very reliable and involved small sample sizes. Objective: To assess differences in mortality between ACP and DCP in a large-scale study. Design setting and participants: Data were downloaded from the Surveillance, Epidemiology, and End Results database in June 2022. Data for 823 939 patients diagnosed with PCa from 2004 to 2019 were examined, excluding cases with survival data missing or pathological types other than DCP and ACP. Outcome measurements and statistical analysis: Prognostic and risk factors for DCP were analyzed by generating a propensity score-matched cohort of DCP and ACP cases (1:5). Adjusted Cox models were constructed to determine hazard ratios (HRs) with 95% confidence intervals (CIs) for cancer-specific mortality (CSM) and overall mortality (OM). Results and limitations: A total of 822 607 cases (99.8%) has ACP and 1332 (0.2%) had DCP. In comparison to ACP, age at diagnosis was significantly lower for DCP (≤66 yr: 38.0% vs 50.7%; p < 0.001) and a higher proportion of DCP patients distant metastases (13.7% vs 5.1%; p < 0.001). In comparison to the ACP group, significantly higher proportions of the DCP group underwent surgery (66.1% vs 38.1%; p < 0.001), radiotherapy (13.7% vs 3.1%; p < 0.001), or systemic therapy (18.2% vs 3.3%; p < 0.001). However, the median overall survival time was significantly shorter for DCP patients (44.0 vs 73.0 mo; p < 0.001). DCP patients also had higher risk of CSM (HR 2.07, 95% CI 1.68-2.56; p < 0.001) and OM (HR 2.73 95% CI 2.42-3.08; p < 0.001) after propensity score matching to adjust for the influence of baseline variables. Subgroup analysis showed that DCP patients who had surgical treatment had better CSM than those without surgery, while DCP patients with regional and lower stage had better OM than those with distant stage (both p < 0.05 for interaction). Conclusions: The risk of CSM and OM is significantly higher for DCP than for ACP. Earlier detection (lower stage) and surgical treatment are beneficial factors for DCP prognosis. Patient summary: We studied survival rates for two different types of prostate cancer. We found that survival is worse for the rarer ductal carcinoma of the prostate (DCP) than for the more common acinar adenocarcinoma of the prostate. Both early diagnosis when the cancer is at a lower stage and surgical treatment are beneficial for survival in patients with DCP.
RESUMEN
The herniation of ureter is rare. A 59-year-old woman with hydronephrosis caused by herniation of ureter through psoas muscle fascia was observed. The patient referred to our clinic with four weeks' history of left flank pain and fever. Computed tomography urography and antegrade combined with retrograde urography revealed tortuous and proximal dilated ureter and hydronephrosis on the left side. Herniation of ureter through psoas muscle fascia was confirmed in operation and laparoscopic ureteroplasty with end to end anastomosis was done. No obvious hydronephrosis or flank pain was observed in follow-up for one and a half year.
RESUMEN
This study explored the role of circulating exosomal microRNA-423-5p in the progression of PCa and its molecular mechanism. First, based on the microarray analysis, microRNA-423-5p was at a high expression level in PCa peripheral blood samples. It was demonstrated that microRNA-423-5p expression in serum exosomes of PCa patients was notably higher than that in healthy people as revealed by qRT-PCR. Further studies indicated that overexpressing microRNA-423-5p promoted cell progression of PCa. Microarray analysis and luciferase gene reporter assay illustrated that FRMD3 was targeted by microRNA-423-5p, and its expression was down-regulated by microRNA-423-5p. While FEMD3 knockdown would reverse the repressive effect of silencing microRNA-423-5p on PCa cell functions. In addition, it was exhibited that exosomes carrying microRNA-423-5p could internalize into PCa cells by labeling and tracing exosomes. Cell function assays and animal experiments manifested those exosomes carrying microRNA-423-5p could enhance PCa cell proliferation, migration, and invasion in vivo. In conclusion, this study indicated that blood circulating exosomal microRNA-423-5p played important roles in PCa cell functions, and illustrated the molecular mechanism of microRNA-423-5p as an oncogene in PCa.
RESUMEN
BACKGROUND: Renal papillary necrosis (RPN) is a rare disease. It is difficult to distinguish RPN with urinary tract obstruction from upper urinary tract occupying lesions. We reported a case of RPN and made a definite diagnosis largely based upon its endoscopic characteristics. CASE SUMMARY: A 75-year-old woman presented with right flank pain, visible hematuria and a body temperature greater than 39 â. Laboratory investigations revealed leukocytosis with 12.7 × 10/L white blood cells and 93.6% neutrophils. Blood creatinine was 333 umol/L. Ultrasonography showed hydronephrosis of the right kidney and a right distal ureteric lesion. After urgent placement of right ureteral double J stent and treatment with antibiotics, the patient's symptoms and the blood abnormalities improved rapidly. Computed tomography urography showed the presence of multiple occupying lesions in the right pelvis. The endoscopic ureteroscopy revealed that renal papillary necrosis and the subsequent migration of sloughed papillae into the upper ureter and calyces. The sloughed papillae appeared like "cottons", which were whitish, soft, and irregularly-shaped without blood supply. In addition, the necrotic and sloughed renal papillae were removed by flexible ureteroscopy to prevent further obstruction. Pathological examination found that infarcted renal papillae were associated with inflammatory exudation. Three months after discharge, follow-up computed tomography urography showed no obvious lesions in the renal pelvis. CONCLUSION: This case revealed the endoscopic features of RPN. In addition, flexible ureteroscopy proves to be vital in diagnosis and treatment of RPN.
RESUMEN
To compare the applicability of 14 equations of estimating glomerular filtration rate (eGFR) before and after nephron-sparing surgery (NSS) for renal function assessment of patients with renal tumors. Preoperative and postoperative GFR is measured by emission computed tomography (ECT) with 99mTc-DTPA as an imaging agent as reference GFR (rGFR) to compare with all formulas. Spearman correlation analysis and Bland-Altman agreement analysis were used to evaluate the correlation between rGFR and eGFR1 to 14 before and after surgery. A total of 50 cases including 22 males and 28 females were included. The results of preoperative eGFR1-14 correlated with rGFR (P < 0.05). The calculation results of all estimation formulas have a significant correlation with preoperative GFR. Preoperative MDRD-I, CKD-EPI SCysC, and FAS Scr-SCysC have good consistency. The CG formula has the highest precision and FAS Scr-SCysC has the highest accuracy. A total of 30 patients followed up after surgery, and postoperative rGFR correlated with CG, CKD-EPI, FAS, and BIS formulas (P < 0.05). But postoperative rGFR has no significant correlation with MDRD and Schwartz (P > 0.05). Postoperative CKD-EPI Scr-SCysC has best consistency, and FAS Scr-SCysC has the highest accuracy and precision. Our data suggest that eGFR equations evaluated by both serum creatinine (Scr) and cystatin C (SCysC) is not necessarily better than those evaluated by one of them alone. Among all enrolled equations, FAS Scr-SCysC is the best one to evaluate postoperative GFR in patients with renal tumors.

Background: To compare the middle-term efficacy and safety results between scrotoscope-assisted (SA) minimally invasive excision and traditional open excision (OE) for the treatment of epididymal mass. Methods: A total of 253 males with surgery excision of epididymal mass from 2012 to 2018 were included in this retrospective study. Patients were divided into two groups: the traditional OE group and the SA group. Patient demographics and intraoperative and postoperative outcomes were obtained and compared between these two groups. Results: About 174 patients (68.8%) underwent SA, and the other 79 (31.2%) underwent OE. Demographic data were similar between the two groups. Compared with OE surgery, SA could significantly shorten the operating time (19.4 ± 4.1 vs. 53.8 ± 12.9 min), reduce blood loss (5.3 ± 1.5 vs. 21.3 ± 5.6 ml), and downsize the operative incision (1.5 ± 0.3 vs. 4.5 ± 0.8 cm). Additionally, postoperative complications were significantly less occurred in the SA group than those in OE (15.5% vs. 21.5%), in particular scrotal hematoma (1.7% vs. 12.7%) and incision discomfort (2.8% vs. 6.3%). Patients in the SA group had a significantly higher overall satisfaction score (94.8 ± 3.7 vs. 91.7 ± 4.9) and a significantly shorter length of hospital stay (4.1 ± 0.9 vs. 5.0 ± 1.5 days) than those in the OE group. No postoperative testicular atrophy occurred in the SA group. Conclusion: SA is emerging as a novel and effective option with promising perspectives for epididymal mass therapy.
RESUMEN
The recently reported prime editor (PE) can produce all types of base substitution, insertion and deletion, greatly expanding the scope of genome editing. However, improving the editing efficiency and precision of PE represents a major challenge. Here, we report an approach termed the homologous 3' extension mediated prime editor (HOPE). HOPE uses paired prime editing guide RNAs (pegRNAs) encoding the same edits in both sense and antisense DNA strands to achieve high editing efficiency in human embryonic kidney 293T cells as well as mismatch repair-deficient human colorectal carcinoma 116 cells. In addition, we found that HOPE shows greatly improved product purity compared to the original PE3 system. We envision that this enhanced tool could broaden both fundamental research and therapeutic applications of prime editing.

PURPOSE: We aimed to evaluate the reliability of a portable device that applies Raman spectroscopy at an excitation wavelength of 1064 nm for the post-operative analysis of urinary stone composition. MATERIALS AND METHODS: Urinary stone samples were obtained post-operatively from 300 patients. All samples were analyzed by the portable Raman spectroscopy system at an excitation wavelength of 1064 nm as well as by infrared spectroscopy (IR), and the results were compared. RESULTS: Both Raman spectroscopy and IR could detect multiple stone components, including calcium oxalate monohydrate, calcium oxalate dihydrate, calcium phosphate, uric acid, cystine, and magnesium ammonium phosphate hexahydrate. The results from 1064-nm Raman analysis matched those from IR analysis for 96.0% (288/300) of cases. Although IR detected multiple components within samples more often than Raman analysis (239 vs 131), the Raman analysis required less time to complete than IR data acquisition (5 min vs 30 min). CONCLUSIONS: These preliminary results indicate that 1064-nm Raman spectroscopy can be applied in a portable and automated analytical system for rapid detection of urinary stone composition in the post-operative clinical setting.

Renal cell carcinoma (RCC) is a major healthcare burden globally. Tumorderived extracellular vesicles (EVs) contribute to the formation of a prometastatic microenvironment. In the present study, we explored the role and mechanism of RCC cell 786Oderived EVs (786OEVs) in RCC. First, 786OEVs were extracted and identified, and EV internalization of RCC cells was observed. RCC cell malignant behaviors and long noncoding RNA (lncRNA) metastasisassociated lung adenocarcinoma transcript 1 (MALAT1) expression patterns were detected before and after 786OEV treatment. MALAT1 was intervened to evaluate RCC cell behaviors. The downstream mechanism involving MALAT1 was predicted. In addition, the relationship among MALAT1, transcription factor CP2 like 1 (TFCP2L1) and ETS protooncogene 1, transcription factor (ETS1) was analyzed. TFCP2L1 expression patterns were measured after 786OEV exposure. Tumor xenograft formation assay and lung metastasis model were adopted to verify the role of 786OEVs in vivo in RCC. It was found that 786OEVs could be internalized by RCC cells. 786OEVs promoted RCC cell malignant behaviors, accompanied by elevated MALAT1 expression levels. The 786OEVs with MALAT1 knockdown attenuated the promotive effect of sole 786OEVs on RCC cells. MALAT1 located ETS1 in the TFCP2L1 promoter and negatively regulated TFCP2L1, and ETS1 protein could specifically bind to MALAT1. 786OEVs enhanced the binding of ETS1 and the TFCP2L1 promoter and decreased TFCP2L1 expression. In vivo, 786OEVs promoted tumor growth and RCC lung metastasis, which was suppressed following inhibition of MALAT1. Our findings indicated that 786OEVs promoted RCC invasion and metastasis by transporting MALAT1 to promote the binding of transcription factor ETS1 and TFCP2L1 promoter.

The study aimed to compare the clinicopathological features and prognosis between type I and type II papillary renal cell carcinoma (PRCC) and to investigate whether the subtypes of PRCC would affect oncological outcomes. A total of 102 patients with PRCC were recruited, of which 42 were type I PRCC and 60 type II. The clinicopathological features and oncologic outcomes of the patients were evaluated. The type II cases had a higher WHO/ISUP grading (P < 0.001), T (P = 0.003), N (P = 0.010) stage and stage grouping (P = 0.011) than the type I. During a median follow-up period of 61.4 months, 1-year cancer specific survival (CSS) of the type I was 100%, 5-year CSS was 95.2%, the 1-year CSS of the type II was 96.2%, and 5-year CSS was 75.7%. The univariate analysis showed that subtype, symptoms, TNM, stage grouping, WHO/ISUP grading and surgical methods appeared to affect prognosis of the patients with PRCC. However, multivariate analysis revealed that only stage grouping was the independent risk factor. After the stage grouping factor was adjusted for the analysis, there were no statistically significant differences in CSS (P = 0.214) and PFS (P = 0.190) between the localized type I and type II PRCC groups. Compared with type I PRCC, type II had higher pathological T, N stage and WHO/ISUP grading. However, it was the Stage grouping that made a great difference to oncological outcomes, rather than the subtype of PRCC.

Objective: To evaluate the modified Zhang's 'three-level' technique of retroperitoneal laparoscopic adrenalectomy (RLA) to treat adrenal lesions for patients with BMI of 25-30 Kg/m2. Methods: A retrospective analysis was performed in all patients with BMI of 25-30 Kg/m2 in our hospital from January 2014 to December 2019. Those who underwent laparoscopic adrenal surgery were divided into two groups on the basis of the technique used: the Zhang's technique (the ZT group) and the modified technique (the MT group). Results: Herein, 170 operations were included (ZT, 91 patients; MT, 79 patients). RLA was successfully performed in all of them. Compared with the ZT group patients, the MT group patients showed shorter operation time (p = 0.007), lesser intraoperative blood loss (p = 0.023), shorter operation time, earlier postoperative diet recovery (p < 0.001), shorter postoperative drainage time (p < 0.001) and shorter postoperative hospitalization period (p = 0.001). It was also worth noting that the unplanned total adrenalectomy rate was significantly less in the MT group than in the ZT group (0% vs. 10.8%, p = 0.020). There was no significant difference in the complications between the two groups (3.3% vs. 2.5%, p = 0.567). Conclusions: We found that MT was a beneficial retroperitoneal laparoscopic treatment for adrenal lesions in patients who had a BMI of 25-30 Kg/m2. It may provide a reference for the treatment of adrenal surgical diseases in such patients.

Traditional open surgery (OS) is usually necessary when testicular torsion (TT) cannot be excluded by scrotal ultrasound. Scrotoscopy has been used as a minimally invasive technique to diagnose or treat scrotal diseases, and it may also play a role in diagnosing TT.A retrospective analysis was performed for patients with TT to evaluate the consistency of scrotoscopy and OS in the diagnosis of TT. In the cases where preoperational Color Doppler ultrasonography was performed, scrotoscopy, open surgery, and confirmed TT were included for future analysis.A total of 43 patients were studied. Twisted testes were retained in 11 cases (25.59%), and the remaining 32 patients (74.41%) underwent orchiectomy. There were significant differences in the diagnostic value between the grading of scrotoscopy and ultrasound, as well as between ultrasound grading and blood supply grading (BSG) (both Pâ<â.05). However, no significant difference was observed between the grading of scrotoscopy and BSG in traditional OS (Pâ>â.05), but a high degree of consistency existed between scrotoscopy grading and BSG in traditional OS (Kappaâ=â0.733, Pâ≤â.001).Our limited data indicate that the diagnosis of testicular torsion by scrotoscopy is highly consistent with that of traditional surgical exploration. Therefore, further studies are necessary to confirm its application value in the future. Scrotoscopy may have potential application value for the patients whom testicular torsion are insufficiently diagnosed but cannot be excluded.
