Objectives:To explore the antiepileptic cellular mechanism of chronic vagus nerve stimulation (VNS).　 Methods: The rats were kindled by intraperitoneal injection of pentylenetetrazol (PTZ) (45mg/kg weight), and chronic VNS was applied to the kindled-rats. The effects of glutamate (Glu) on the intracellular free calcium (［Ca2+］i) of cortical and hippocampal neurons of normal, PTZ-kindled and VNS-treated rats were examined with fluorescence spectrophotometry respectively. The behavioral changes of all rats were observed. 　Results: The neuronal ［Ca2+］i of the VNS-treated rats were significantly lower than that of the PTZ-kindled rats. VNS could significantly inhibit the augmentation of neuronal ［Ca2+］i induced by Glu. Behavioral changes demonstrated that VNS could significantly reduce the severity and prolong the latency of seizures of PTZ-kindled rats. 　Conclusions: VNS could significantly inhibit the kindling effect of PTZ and reduce the excitability of neurons induced by Glu. VNS might exerted the antiepileptic effects by influencing the activation of neural receptors.

Objective To explore the effect of group management mode on compliance of pelvic floor function exercise for patients with post partum urinary incontinence (PPUI). Methods A total of 80 cases of patients with PPUI were randomly divided into the observation group and the control group. Patients in the control group received one-to-one routine health guidance. Patients in the observation group received group management mode including special subject teaching guidance, induction and communication between patients. Three months after the intervention, two groups of patients were evaluated at six months after postpartum by the pelvic floor muscle strength, one-hour urine pad test and pelvic floor muscle function exercise compliance. Results Six months after postpartum, the cure rate of the pelvic floor muscle strength was 100%(40/40) for typeⅠmuscle, 100%(40/40) for typeⅡmuscle in the observation group. In the control group, the cure rate for typeⅠmuscle was 70%(28/40) and 65%(26/40) for type Ⅱmuscle. The difference between these two groups was statistically significant (χ2=14.118, 16.970, P=0.000). The total effective rate of urinary incontinence was 100.0%(40/40) in the observation group, 67.5% (16/40) in the control group, and there was statistical significance (χ2=25.232, P=0.000). Evaluation of the compliance of pelvic floor function exercise showed that the rates were 72.5% (29/40) for complete compliance, 27.5%(11/40) for incomplete compliance and 0 for total non-compliance in the observation group. In the control group, these rates were 2.5%(1/40), 55.0%(22/40), 42.5%(17/40). And there was statistical significance as well (χ2=54.847, P=0.000). Conclusions Group management mode can improve the compliance of pelvic floor muscle function exercise and the strength of pelvic floor muscle, and improve the degree of urinary incontinence in postpartum patients with urinary incontinence.
