With advances in imaging and the growing emphasis on nephron preservation, partial nephrectomy has become central in the management of T1 renal tumors and has gradually been extended to complex renal masses, where surgical challenges are greater.This article reviews the current status, key technical advances, and clinical application strategies of minimally invasive partial nephrectomy for complex renal tumors.It compares the suitability and advantages of laparoscopic and robot-assisted approaches across different levels of tumor complexity, and summarizes the value of three-dimensional reconstruction, precise selective vascular control, and intraoperative navigation in improving surgical safety and controllability. It elaborates on the management pathways and technical strategies for typical scenarios such as renal hilar lesions, completely intrarenal tumors, cystic tumors, and multifocal tumors, and summarizes operative techniques and perioperative risk-control considerations for high-risk cases, including solitary kidneys, T2 or higher stage tumors, tumors with local invasion of the renal pelvis, and those complicated with vascular tumor thrombus.The article also briefly discusses controversies regarding indication boundaries and the balance between functional preservation and oncologic safety, and highlights the trend toward a standardized, reproducible precision surgery paradigm supported by intelligent planning and quality-control systems.

Objective To explore the research hotspots and developmental trends in urological education through a bibliometric analysis. Methods Relevant literature on urological education was retrieved from the Web of Science Core Collection and the China National Knowledge Infrastructure (CNKI) databases, covering all records up to Sep.16, 2025.A comprehensive bibliometric analysis was performed on the retrieved publications. Results A total of 303 Chinese and 290 English articles were collected.The annual number of publications demonstrated an overall upward trend.Harvard University in the United States was the most productive institution in this field. Conclusion Urological clinical education has attracted increasing attention from clinicians and medical trainees.Highly cited studies consistently highlight three actionable priorities for urological education:firstly, improving long-term knowledge retention through structured, spaced, and feedback-rich learning designs; secondly, standardizing simulation-based skills training with validated assessment and staged credentialing; thirdly, strengthening training system resilience while expanding non-technical skills training.These directions provide implementable pathways for optimizing urological teaching practices and the standardized residency training programs.

This research study focuses on addressing the limitations of current neuropathic pain (NP) treatments by developing a novel dual-target modulator, E0199, targeting both NaV1.7, NaV1.8, and NaV1.9 and KV7 channels, a crucial regulator in controlling NP symptoms. The objective of the study was to synthesize a compound capable of modulating these channels to alleviate NP. Through an experimental design involving both in vitro and in vivo methods, E0199 was tested for its efficacy on ion channels and its therapeutic potential in a chronic constriction injury (CCI) mouse model. The results demonstrated that E0199 significantly inhibited NaV1.7, NaV1.8, and NaV1.9 channels with a particularly low half maximal inhibitory concentration (IC50) for NaV1.9 by promoting sodium channel inactivation, and also effectively increased KV7.2/7.3, KV7.2, and KV7.5 channels, excluding KV7.1 by promoting potassium channel activation. This dual action significantly reduced the excitability of dorsal root ganglion neurons and alleviated pain hypersensitivity in mice at low doses, indicating a potent analgesic effect without affecting heart and skeletal muscle ion channels critically. The safety of E0199 was supported by neurobehavioral evaluations. Conclusively, E0199 represents a ground-breaking approach in NP treatment, showcasing the potential of dual-target small-molecule compounds in providing a more effective and safe therapeutic option for NP. This study introduces a promising direction for the future development of NP therapeutics.

Objective:To compare the safety and efficacy of novel en-bloc Holmium laser enucleation of the prostate(HoLEP)with complete membranous urethral mucosa sparing technique with traditional 2-lobe technique HoLEP in benign prostatic hyperplasia(BPH)treatment.Methods:The data of BPH patients treated with HoLEP from January 2023 to May 2024 in Xinhua Hospital,School of Medicine,Shanghai Jiaotong University were retrospectively reviewed. Seventy-two patients received novel en-bloc HoLEP with complete membranous urethral mucosa sparing technique(novel en-bloc group),while 79 patients received traditional 2-lobe technique HoLEP(traditional 2-lobe technique group).There was no significant difference between novel en-bloc group and traditional 2-lobe technique group in the age[(71.0 ± 7.1)years vs.(69.8 ± 6.5)years],body mass index[(24.5 ± 2.8)kg/m 2 vs.(23.9 ± 3.5)kg/m 2],international prostate symptom score(IPSS)[26.0(22.0,28.0)vs. 25.0(22.0,28.0)],quality of life(QOL)score[5.0(5.0,6.0)vs. 5.0(5.0,6.0)],prostate sepcific antigen(PSA)[4.98(2.40,11.11)ng/ml vs. 4.38(1.62,7.54)ng/ml]and prostate volume[(74.06 ± 42.67)ml vs.(70.10 ± 33.94)ml](all P > 0.05). The incidence of acute urinary retention in novel en-bloc group was significantly higher than that in traditional 2-lobe technique group[31.94%(23/72)vs. 17.72%(14/79), P = 0.042].The procedure of novel en-bloc was shown as followed:expose the prostatic capsule near the verumontanum and expand the initial capsule plane on both sides. The prostatic urethral mucosa was cut off in a circular pattern medial to the external urethral sphincter,which could form a complete “circular mucosal pad”. Seperate the apical gland along the capsule plane at 12 o’clock and expand the capsule plane until the bladder neck was reached.The bladder neck was then used as a marker so as to separate the glands on both sides along the capsule plane and merge with the initial plane. The entire lobe of the prostate was finally removed along the surgical capsule of the prostate. The procedure of traditional two lobe method was shown as followed:expose the prostatic capsule near the verumontanum and then divide the prostate into two lobes by longitudinal incision at 6 and 12 o’clock. The mucosa was horizontally cut at 12 o’clock,medial to the external urethral sphincter in order to preserve the apical urethral mucosal flap. The twp lobes were then removedd respectively along the capsule layer. The surgery-related indicators,perioperative complications and other data were compared between the two groups,as well as IPSS,QOL score,lower urinary tract symptoms,and the incidence of stress urinary incontinence in the two groups 1 month after surgery. Results:Compared with the patients underwent 2-lobe technique HoLEP,the patients underwent novel en-bloc HoLEP had lower hemoglobin loss[0.50(-5.50,7.50)g/L vs. 7.00(1.00,13.25)g/L, P = 0.003],lower operation time[(72.06 ± 34.37)min vs.(85.42 ± 40.35)min, P = 0.030],higher surgical efficacy[(0.72 ± 0.31)g/min vs.(0.55 ± 0.29)g/min, P = 0.002]and lower incidence of stress urinary incontinence one month after operation[2.78%(2/72)vs. 10.13%(8/79), P = 0.070]. There was no significant difference in the incidence of postoperative gross hematuria[0 vs. 2.53%(2/79)],postoperative sepsis[1.39%(1/72)vs. 1.27%(1/79)],postoperative dysuria[4.17%(3/72)vs. 5.06%(4/79)],postoperative IPSS improvement[12.0(11.0,13.0)vs. 12.0(10.0,14.0)]and postoperative QOL improvement[3.0(2.0,3.0)vs. 3.0(2.0,3.0)]between the two groups( P > 0.05). The patients were further divided into 2 sub-groups according to whether prostate volume ≥ 60 ml or not. In the patients of prostate volume < 60 ml,surgical efficacy was significantly higher in novel en-bloc HoLEP group than that in traditional 2-lobe technique group[(0.55 ± 0.25)g/min vs.(0.41 ± 0.19)g/min, P = 0.028]. In the patients of prostate volume ≥ 60 ml,the surgical efficacy of novel en-bloc HoLEP was also higher[(0.88 ± 0.28)g/min vs.(0.66 ± 0.31)g/min, P = 0.006]. Conclusions:Novel en-bloc HoLEP with complete membranous urethral mucosa sparing technique was demonstrated to has lower blood loss,shorter operation time,higher surgical efficacy and lower incidence of stress urinary incontinence,which is suitable of all sizes of prostate.

OBJECTIVE To investigate the impacts of andrographolide on sciatic nerve function injury in diabetic peripheral neuropathy (DPN) rats by regulating high-mobility group protein box 1 (HMGB1)/receptor for advanced glycation end products (RAGE) signal pathway. METHODS A total of 84 rats were randomly divided into the control group (normal saline), DPN group (normal saline), low-dose andrographolide group (0.833 mg/kg), high-dose andrographolide group (3.332 mg/kg), lipoic acid group (positive control, 0.1 g/kg), recombinant rat HMGB1 protein (rHMGB1) group (8 μg/kg), and high-dose andrographolide+ rHMGB1 group, with 12 rats in each group. All rats except those in the control group were fed with high glucose and high fat diet combined with intraperitoneal injections of streptozotocin to establish the DPN rat model. After 24 hours of successful modeling, medication was administered daily for 8 weeks. The changes in fasting blood glucose, mechanical pain threshold, heat pain threshold and sciatic nerve conduction velocity were detected. Pathological changes in the sciatic nerve of rats and the activity of superoxide dismutase (SOD) and the content of malondialdehyde (MDA) in the sciatic nerve of rats were also detected. Besides, the expressions of HMGB1, RAGE proteins and phosphorylation level of nuclear factor κB p65(NF-κB p65) protein in rat sciatic nerves were found. RESULTS Compared with the control group, the pathological damage of the sciatic nerve of rats in the DPN group was strengthened, the fasting blood glucose, heat pain threshold, MDA content and the 诊治。E-mail:dqiaur@163.com expressions of HMGB1, RAGE proteins and phosphorylation level of NF-κB p65 protein were increased (P<0.05), while the mechanical pain threshold, sensory nerve conduction velocity, motor nerve conduction velocity, and SOD activity were decreased/slowed down (P<0.05). Compared with the DPN group, the above indexes were significantly potentiated in the andrographolide low- and high-dose groups and lipoic acid group (P<0.05), and the corresponding trends in the rHMGB1 group were opposite to those in the above three administration groups (P<0.05). Moreover, rHMGB1 attenuated the hypoglycemic effect of high-dose andrographolide on blood glucose and the improvement of oxidative stress injury in the sciatic nerve of DPN rats (P<0.05). CONCLUSIONS Andrographolide may reduce blood glucose by inhibiting the HMGB1/RAGE pathway and oxidative stress, thus ameliorating sciatic nerve injury in DPN rats.

Objective To study the effect of curcumin on wound healing in diabetic mice.Methods The effect of curcumin on fibroblast activity was examined by the MTT assay,and the ROS detection kit was used to detect the effect of curcumin on the hydrogen peroxide-induced scavenging effect of reactive oxygen species(ROS)in fibroblasts.Q-PCR was used to detect the effects of curcumin on the mRNA expression of inflammatory factors CD86,CD206,IL-6 and ARG1 in lipopolysaccharide-induced RAW 264.7macrophage.The wound model of diabetes was established by intraperitoneal injection of streptozotocin.Hematoxylin-eosin(HE)and Masson staining were used to evaluate wound healing and histomorphological changes,and immunofluorescence staining was used to determine skin tissue α-smooth muscle actin,CD86 and CD206 expression.Results Curcumin had no significant effect on fibroblast activity at concentrations less than 20 mol·L-1;curcumin scavenged hydrogen peroxide-induced intracellular ROS in fibroblasts;curcumin decreased the mRNA expression of CD86 and IL-6 while increasing CD206 and ARG1 in lipopolysaccharide-induced RAW 264.7 macrophages.After in vivo administration,compared with the control group,wound healing was significantly faster in the curcumin(15,30 mg·mL-1)group after 7 d and 14 d of wound perforation(P<0.01).Hematoxylin-eosin(HE)and Masson staining results confirmed a significant increase in granulation tissue and a significant increase in collagen deposition in the curcumin(15,30 mg·mL-1)group.Immunofluorescence assay showed significantly higher expression of CD206(P<0.01)and significantly reduced expression of CD86(P<0.01)in the skin wounds of curcumin(15,30 mg·mL-1)for 14 d.In addition,the expression of α-SMA in the wound of the high-dose curcumin(30 mg·mL-1)group was significantly higher than that of the low-dose curcumin group(P<0.01).Conclusion Curcumin accelerates diabetic wound healing by promoting granulation tissue proliferation and collagen deposition in refractory diabetic wounds in mice through its anti-inflammatory and antioxidant effects.
9.Research on the role of P2X receptor channel protein in the progression of solid tumors
Journal of Xi'an Jiaotong University(Medical Sciences) 2024;45(4):686-694
Adenosine triphosphate(ATP)is the most common energy supplier in living organisms and also an important signaling molecule.The expression level of ATP is significantly upregulated in the tumor microenvironment.The purinergic receptor ion channel P2X is widely distributed in various tissues.ATP can specifically activate the P2X receptor to induce the opening of gated ion channels in the microenvironment,thereby affecting the downstream signal transduction in regulating the physiological activities.Notably,abnormal purinergic signal plays an important role in tumor progression.This review focuses on the expression,structure,and function of the P2X receptor protein family.It also elucidates the mechanisms by which the P2X receptor family participates in the progression of various solid tumors,as well as research on targeted P2X family for tumor therapy.These studies will enrich the basic research theory related to purinergic signaling and provide the new targets and strategies for clinical therapy of solid tumors by targeting P2X family.
