OBJECTIVETo study the toxic mechanism of toxic raphides from Pinellia ternata.

METHODMouse peritoneal macrophage in vitro culture model was adopted to study dose-dependent and time-dependent curves of toxic raphides, with TNF-alpha, IL-1beta and IL-6 in supernatant as indexes. Scanning electron microscopy was used to observe the changes in surface morphology of raphides-treated macrophages. Macrophages-neutrophils co-cultured the transport model to study the effect of toxic raphides' stimulation of macrophages on neutrophils migration.

RESULTToxic raphides' stimulation of macrophages could cause the increase in the levels of TNF-alpha, IL-1beta and IL-6 released, and showed dose dependence and time dependence. Scanning electron microscopy showed that toxic raphides were swallowed by macrophages, with notable cell membrane creases, increase in the number of pseudopods and decrease in integrity of cell membranes, and could significantly induce migration of neutrophils.

CONCLUSIONThe inflammatory process induced by toxic raphides is mainly mediated by macrophages. The toxic mechanism of toxic raphides from P. ternata is that toxic raphides penetrate into tissues to activate resident macrophages, release phagocytic and inflammatory cytokines, and cause migration of neutrophils, which finally results in acute inflammatory response.

Hyperpolarization-activated cyclic nucleotide-gated (HCN) channels are confirmed to be expressed in bladder interstitial Cajal-like cells (ICC-LCs), but little is known about their possible role in cystitis-associated bladder dysfunction. The present study aimed to determine the functional role of HCN channels in regulating bladder function under inflammatory conditions. Sixty female wild-type C57BL/6J mice and sixty female HCN1-knockout mice were randomly assigned to experimental and control groups, respectively. Cyclophosphamide (CYP)-induced cystitis models were successfully established in these mice. CYP treatment significantly enhanced HCN channel protein expression and I(h) density and significantly altered bladder HCN1 channel regulatory proteins. Carbachol (CCH) and forskolin (FSK) exerted significant effects on bladder ICC-LC [Ca²⁺]i in CYP-treated wild-type (WT) mice, and HCN1 channel ablation significantly decreased the effects of CCH and FSK on bladder ICC-LC [Ca²⁺]i in both naive and CYP-treated mice. CYP treatment significantly potentiated the spontaneous contractions and CCH (0.001-10 µM)-induced phasic contractions of detrusor strips, and HCN1 channel deletion significantly abated such effects. Finally, we demonstrated that the development of CYP-induced bladder overactivity was reversed in HCN1 -/- mice. Taken together, our results suggest that CYP-induced enhancements of HCN1 channel expression and function in bladder ICC-LCs are essential for cystitis-associated bladder hyperactivity development, indicating that the HCN1 channel may be a novel therapeutic target for managing bladder hyperactivity.
