Antioxidant and antiaging effect of traditional Thai rejuvenation medicines in Caenorhabditis elegans / 中西医结合学报

OBJECTIVE@#This study explored the rejuvenation mechanisms of Thai polyherbal medicines using different approaches, including in vitro methods, as well as a well-defined nematode model, Caenorhabditis elegans.@*METHODS@#THP-R-SR012 decoction was selected from 23 polyherbal medicines, based on metal-chelating and chain-breaking antioxidant capacities. The influences of this extract on the survival and some stress biomarkers of C. elegans under paraquat-induced oxidative stress were evaluated. Furthermore, lifespan analysis and levels of lipofuscin accumulation were examined in senescent nematodes. The phytochemical profile of THP-R-SR012 was analyzed.@*RESULTS@#Supplementation with THP-R-SR012 decoction significantly increased the mean lifespan and reduced the oxidative damage to C. elegans under oxidative stress conditions. Further, THP-R-SR012 supplementation slightly influenced the lifespan and the level of lipofuscin accumulation during adulthood. Antioxidant-related phytochemical constituents of THP-R-SR012 decoction were rutin, naringenin, 3,4-dihydroxybenzoic acid, gallic acid, glycyrrhizic acid, demethoxycurcumin and 18α-glycyrrhetinic acid.@*CONCLUSION@#The antioxidant potential of THP-R-SR012 was due to its scavenging properties, its enhancement of antioxidant-related enzyme activities, and the presence of the antioxidant-related compound. These results support the traditional use of THP-R-SR012 decoction as a tonic for nourishing and strengthening the whole body.

Clinical analysis and management of disappointing early urination after TURP / 中华男科学杂志

<p><b>OBJECTIVE</b>To explore the etiology and management of disappointing early urination in patients with benign prostatic hyperplasia (BPH) following transurethral resection of the prostate (TURP).</p><p><b>METHODS</b>The clinical data and management of 58 cases of disappointing urination within 3 months after TURP were reviewed.</p><p><b>RESULTS</b>Of the total number of patients with disappointing early urination after TURP, 7 (12%) underwent a second operation, 6 (10%) received outpatient treatment, and the other 45 (78%) showed spontaneous improvement within 1 year with no further treatment.</p><p><b>CONCLUSION</b>The causes of disappointing early urination after TURP included bladder neck contracture, urethral stricture and urinary tract infection, which necessitate secondary treatment. And a greater proportion of the patients showed functional lability of the bladder detrusor muscle, which could be spontaneously improved within 1 year after TURP.</p>
