To study the toxicokinetics of bakuchiol, hepatic and renal toxicity in rats after single oral administration of Psoraleae Fructus and combined with Glycyrrhizae Radix et Rhizoma, in order to provide scientific evidences for clinical safe medication use. A total of 35 SD rats were randomly divided into seven groups: vehicle (distilled water) control group, Glycyrrhizae Radix et Rhizoma group, positive control (aristolochic acid A) group, Psoraleae Fructus (40 g x kg(-1)) group( both male and female rats), Psoraleae Fructus and Glycyrrhizae Radix et Rhizoma (40 +20) g x kg(-1) group (both male and female rats). HPLC-UV method was used to determine the concentration of bakuchiol in rat plasma at different time points after single oral administration. Plasma alanine transaminase (ALT), aspartate aminotransferase (AST), blood urea nitrogen (BUN), plasma creatinine (Cr), N-acetyl-β-D-glucosaminidase (NAG) and kidney injury molecule 1 (Kim-1) were measured after administration for 24 h. The main toxicokinetics parameters of bakuchiol in rats exert significantly gender difference. When Psoraleae Fructus combination with Glycyrrhizae Radix et Rhizoma, the total area under the plasma concentration-time curve( AUC), C(max), and plasma clearance (CL) of bakuchiol were increased, respectively; CL, half-life (t½) were decreased, and T(max) were prolonged. The biochemical indicators (including ALT, AST, BUN, Cr and KIM-1 level) in different dose of Psoraleae Fructus groups, were found no statistically significant difference when compared with vehicle control group. The level of NAG in both Psoraleae Fructus and compatibility with Glycyrrhizae Radix et Rhizoma groups were significant increased (P < 0.05). There are obvious effects on toxicokinetics of bakuchiol in rats when Psoraleae Fructus combined with Glycyrrhizae Radix et Rhizoma. Renal toxicity induced by Psoraleae Fructus at high dose was observed after single oral administration and no liver damage in rats was found.

A HPLC-MS/MS multiple-reaction monitoring (MRM) quantitative analysis was made to establish a determination method for drug concentrations of costunolide (Co) and dehydrocostuslactone (De) in blood samples in the positive ion mode, with diazepam as the internal standard substance, in order to study the pharmacokinetic process of sesquiterpene lactones costunolide and dehydrocostuslactone after the oral administration of Weichang'an pills, and provide an theoretical basis for further studies on the substance basis for the anti-diarrhea effect of Weichang'an pills. In the blood samples, Co and De showed a good linearity within concentration ranges 0.700 0-769.7, 2.510-956.0 μg x L(-1), respectively. The results of precision, stability and recovery experiences proved the stability and reliability of the plasma concentration determination method. After the oral administration, the concentrations of Co and De in plasma increased with the increase in dose, with T(max) between 10.65-12.98 h, indicating a long time to reach peak plasma concentrations; C(max) of costunolide and dehydrocostuslactone ranged between 3.750-5.450,15.34-44.52 μg x L(-1), respectively. The in vivo adsorption of Co and De conformed to the one-compartment model, with a longer time to attain the peak plasma concentrations. These results provided an experimental basis for revealing the active substance basis and clinical medication of Weichang'an pills.

OBJECTIVETo investigate the effects of serotonin (5-HTIA) receptors in the hippocampal dentate gyrus (DG) on active avoidance learning in rats.

METHODSTotally 36 SD rats were randomly divided into control group, antagonist group and agonist group(n = 12). Active avoidance learning ability of rats was assessed by the shuttle box. The extracellular concentrations of 5-HT in the DG during active avoidance conditioned reflex were measured by microdialysis and high performance liquid chromatography (HPLC) techniques. Then the antagonist (WAY-100635) or agonist (8-OH-DPAT) of the 5-HT1A receptors were microinjected into the DG region, and the active avoidance learning was measured.

RESULTS(1) During the active avoidance learning, the concentration of 5-HT in the hippocampal DG was significantly increased in the extinction but not establishment in the conditioned reflex, which reached 164.90% ± 26.07% (P <0.05) of basal level. (2) The microinjection of WAY-100635 (an antagonist of 5-HT1A receptor) into the DG did not significantly affect the active avoidance learning. (3) The microinjection of 8-OH-DPAT(an agonist of 5-HT1A receptor) into the DG significantly facilitated the establishment process and inhibited the extinction process during active avoidance conditioned reflex.

CONCLUSIONThe data suggest that activation of 5-HT1A receptors in hipocampal DG may facilitate active avoidance learning and memory in rats.

OBJECTIVETo study possible mechanisms of Shangjuxu (ST37) and the large intestine.

METHODSTotally 40 SD rats were selected. The distension of end colon was used as injured afferent stimulus. Activities of locus coeruleus (LC) neurons were recorded by extracellular microelectrode technique. Shangjuxu (ST37) and Hegu (L14) were needled to observe general features of discharge reactions, distention of colon induced discharge reactions of LC, and its effects on distention of colon induced discharge reactions of LC.

RESULTSDistention of colon could induce incrased discharge of LC neurons by 127.33% ± 45.48%. But needling at Shangjuxu (ST37) and Hegu (L14) could inhibit this injured response by 38.24% ± 7.69% and 21.29% ± 13.16% respectively (all P < 0.01).

CONCLUSIONSNeedling at Shangjuxu (ST37) and afferent signals of colon distension converged and interacted with each other. Needling at Shangjuxu (ST37) could significantly inhibit colon distension induced discharge of LC neurons, which might be one of mechanisms for Shangjuxu (ST37) and the large intestine relationship.

Objective:To describe the electroclinical features of the coexistence of epilepsy and narcolepsy.Methods:The electroencephalography database was searched using the terms “epilepsy” and “narcolepsy” over a four-year period from January 2016 to December 2019 in the Xijing Hospital. The clinical and electrophysiological characteristics of patients with coexistence of epilepsy and narcolepsy were studied.Results:Five patients with comorbidity for epilepsy and narcolepsy were found, of which three patients were female, two patients were male. The age at epilepsy onset and narcolepsy onset was 2-12 years and 8-17 years, respectively. There were two patients with juvenile myoclonic epilepsy, one with sleep-related hypermoter epilepsy, one with epilepsy with retardation of brain development, one with symptomatic epilepsy with cognitive decline. All the patients had narcolepsy with cataplexy, which followed the onset of epilepsy by three months to eight years. All the patients accepted 24 h video electroencephalography monitoring and multiple sleep latency test. Interictal epileptic discharges were found, mean sleep latency was<8 min, and two or more sleep onset rapid eye movement periods were recorded. Duloxetine hydrochloride can effectively improve the drowsiness and catalepsy symptoms of narcolepsy, and seizures did not worsen in patients using duloxetine hydrochloride.Conclusions:Both generalized and focal epilepsy can occur in narcolepsy with cataplexy. Duloxetine hydrochloride may be safe and effective in treating narcolepsy in patients with epilepsy.
