Effect of different anesthetic methods on cellular immune functioning and the prognosis of patients with ovarian cancer undergoing oophorectomy

The present study aimed to explore the effects of different anesthetic methods on cellular immune function and prognosis of patients with ovarian cancer (OC) undergoing oophorectomy. A total of 167 patients who received general anesthesia (GA) treatment (GA group) and 154 patients who received combined general/epidural anesthesia (GEA) treatment (GEA group) were collected retrospectively. Each group selected 124 patients that met the inclusion and exclusion criteria for further study. ELISA and radioimmunoassay were employed to detect levels of IL-2, TNF-α, and CA-125. The rates of tumor-red cell rosette (RTRR), red cell immune complex rosette (RRICR), and red cell C3b receptor rosette (RRCR) were also measured. Systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) were determined by hemodynamics. The levels of tumor necrosis factor-α (TNF-α) and interleukin (IL)-2 decreased at 1 h intraoperation (T2), but increased 24-h post surgery (T3). The levels of TNF-α and IL-2 were recovered faster in the GEA group than in the GA group. The GA group exhibited greater levels of CA-125 expression than in the GEA group. The levels of RTRR, RRICR, and RRCR; ratios of CD3+, CD4+, CD4+/CD8+, CD16+, and CD56+ at 30 min after anesthesia (T1), T2, T3 and 48 h after the operation (T4) and levels of SBP, DBP, and HR at T1, T2, and T3 displayed increased levels in the GEA group than in the GA group. At 72-h post surgery (T5), the 5-year survival rate significantly increased in the GEA group compared with the GA group. GEA to be more suitable than GA for surgery on OC patients.

The Dysregulated Podocyte Phenotype

Podocytes are highly differentiated, postmitotic cells, whose function is largely based on their complex cytoarchitecture. The differentiation of podocytes coincides with progressive expression of maturity markers, including WT-1, CALLA, C3b receptor, GLEPP-1, podocalyxin, and synaptopodin. In collapsing forms of focal segmental glomerulosclerosis (FSGS), including idiopathic FSGS and HIV-associated nephropathy, podocytes undergo characteristic, irreversible ultrastructural changes. This study analyzes the expression pattern of the above differentiation markers and of the proliferation marker Ki-67 in collapsing idiopathic FSGS and HIV-associated nephropathy compared with minimal change disease, membranous glomerulopathy, as well as normal adult and fetal human kidney. In minimal change disease and membranous glomerulopathy, all mature podocyte markers were retained at normal levels despite severe proteinuria and foot process fusion; no cell proliferation was observed. In contrast, in collapsing idiopathic FSGS and HIV-associated nephropathy, there was disappearance of all markers from all collapsed glomeruli and of synaptopodin from 16% of noncollapsed glomeruli. This phenotypic dysregulation of podocytes was associated with cell proliferation in both diseases. It is concluded that the loss of specific podocyte markers defines a novel dysregulated podocyte phenotype and suggests a common pathomechanism in collapsing FSGS, whether idiopathic or HIV-associated.
