Objective: To investigate the safety and effect of nephron-sparing surgery (NSS) in treatment of T1a and T1b renal cell carcinoma.
Methods: Retrospective analyzed the clinical data of 101 patients with T1 renal cell carcinoma underwent NSS from November 1999 to December 2009.Including 79 male and 22 female with the mean age of 52.3 years (ranged 28 to 79 years). Based on tumor pathologic diameter, 101 patients were divided into T1a group with 62 patient and T1b group with 39 cases. Demographic, intraoperative, postoperative and follow-up data were compared between the 2 groups.
Results: The operation were performed successfully in all the 101 cases. The mean operation time was (151 ± 80) min in group T1a and (158 ± 50) min in group T1b with no statistical difference (P = 0.32). The mean blood loss was (322 ± 596) ml in group T1a and (308 ± 239) ml in group T1b (P = 0.45). Postoperative follow-up ranged from 8 to 102 months with a mean of 38.4 months. One patient in T1b group died of distant metastasis 36 months after operation. Others were no tumor recurred.
Conclusion: Nephron-sparing surgery is safe and effective for the treatment of T1a and T1b renal cell carcinoma.

Antibody-mediated protection against pathogens is crucial to a healthy life. However, the recent SARS-CoV-2 pandemic has shown that pre-existing comorbid conditions including kidney disease account for compromised humoral immunity to infections. Individuals with kidney disease are not only susceptible to infections but also exhibit poor vaccine-induced antibody response.

AAV vectors show promise for gene therapy; however, kidney gene transfer remains challenging. Here we conduct a barcode-seq-based comparison of 47 AAV capsids administered through different routes in mice, followed by individual validation. We find that local delivery of AAV-KP1, but not AAV9, via the renal vein or pelvis effectively transduces proximal tubules with minimal off-target liver transduction, while systemic AAV9, but not AAV-KP1, enhances proximal tubule and podocyte transduction in chronic kidney disease.

Dysregulated IL-10 producing regulatory B cells (Bregs) are associated with the progression of systemic lupus erythematosus. An immunomodulatory role of heat shock proteins (HSPs) is implicated in autoimmune diseases. However, the molecular basis underlying the role of Hspa13 in regulating Bregs function and lupus pathogenesis remains unclear.

A 63-year-old woman undergoing peritoneal dialysis (PD) presented to our hospital with abdominal pain, diarrhea, and cloudy PD effluent. An elevated white blood cell count in the PD effluent led to a diagnosis of PD-associated peritonitis. She was subsequently started on intraperitoneal cefazolin and ceftazidime, after which her condition improved rapidly.

Kidney immune homeostasis is intricately linked to T cells. Inappropriate differentiation, activation, and effector functions of T cells lead to a spectrum of kidney disease. While executing immune functions, T cells undergo a series of metabolic rewiring to meet the rapid energy demand.
