Chinese Journal of Pharmacology and Toxicology 2017;31(3):231-236
OBJECTIVE To evaluate the anti-vertigo effect of phencynonate hydrochloride. METHODS To detect the improvement of phencynonate hydrochloride on cerebral blood flow, a rat model wa s es?tablished with bilateral common carotid arteries occlusion. Phencynonate hydrochloride 0.1-4.0 mg·kg-1 was ig given, twice a day for three consecutive days and the alteration of cerebral blood flow was measured with laser Doppler flowmetry. Rotating acceleration equipment was used to provocate mouse vertigo for 30 min, and the spontaneous locomotor activities were tested for occurrence of vertigo in mice. Phencynonate hydrochloride 1.4-5.6 mg·kg-1 was ig given before rotating acceleration. Gastric phenol red emptying rate was used to determine the anti-nausea effect of the test drug in mice 30 min after phencynonate hydrochloride 1.4-8.4 mg·kg-1 was ig given. RESULTS The cerebral blood flow of the rat model with bilateral common carotid arteries occlusion was reduced significantly after 24 h (P<0.01). Compared with the model group, phencynonate hydrochloride (0.5, 2.0 and 4.0 mg · kg-1) increased the cerebral blood flow in a dose-dependent manner in rats with cerebral ischemia (P<0.01). The spontaneous locomotor activities were significantly reduced after vertigo stimulation in mice (P<0.05). Compared with the model group, phencynonate hydrochloride (2.8 and 5.6 mg · kg-1) increased the movement distance and speed of vertigo mice (P<0.05). Phencynonate hydrochloride (2.8, 5.6 and 8.4 mg·kg-1) inhibited the gastric emptying of mice (P<0.05). CONCLUSION Phecynonate hydrochloride can improve the cerebral blood flow and locomotor activities in vertigo rats, while inhibiting gastric emptying, which points to the therapeutic potential of phencynonate hydrochloride for vertigo in clinic.

Objective: To study the efficiency and prognosis of preoperative transcatheter arterial chemoembolization(TACE)treatment in patients with hepatocellular carcinoma(HCC)after hepatectomy. Methods: The clinical pathological data of 479 patients with resectable HCC from 1998 to 2007 were analyzed retrospectively. Fifty patients had preoperative TACE, 379 cases had not and others were lost of follow up or dead. Clinical pathological data, tumor-free survival rate and overall survival rate after hepatectomy were analyzed. Results: There was a significantly difference in the age and the tumor grade between the groups, other clinical pathological factors were no difference. The preoperative TACE group was younger than non-TACE group (?2=6.228, P=0.012), And had lower tu-mor grade, more tumor necrosis (?2=53.874, P=0.000). The disease tumor-free survival rate and overall survival rate were no difference between the groups (?2=0.736, P=0.391;?2=0.000, P=0. 995). Conclusions: For the unresectable HCC patients by one-stage operation, the preoperative TACE treatment has no adverse effect. However, tumor-free survival rate and overall survival rate are similar to non-TACE group.
