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.

In order to investigate the mechanism of elevated vascular endothelial growth factor (VEGF) in peritoneal fluids from patients with endometriosis, macrophages were recovered from peritoneal fluids obtained at the time of diagnostic laparoscopy from infertile women with endometriosis (EMT group, n=20) and without endometriosis (control group, n=20). Macrophages were cultured in vitro. The VEGF levels of peritoneal fluid and the supernatant of macrophages culture were determined by enzyme linked immunoassay (ELISA). Meanwhile, the eutopic (n=20) and ectopic endometrium (n=20) from endometriosis patients, and normal edometrium (n=20) from non-endometriosis patients were obtained for the analysis of VEGF expression by labeled Streptavidin Biotin (LSAB). It was found that VEGF levels in peritoneal fluid and macrophages culture supernatant were significantly higher in EMT group than in control group (P<0.01). In normal endometrium, VEGF showed a cyclic changes and similar in eutopic and ectopic endometrium from patients with endometriosis. There was no difference in the intensity of VEGF in endometrium between two groups within each menstrual phase. It is suggested that altered VEGF production by peritoneal macrophages and ectopic endometrium secretion may contribute to the elevated VEGF levels in the peritoneal fluid of patients with endometriosis.

A survey and analysis were conducted at the end of 2002 of urban community health service institutions in 31 provinces, autonomous regions and municipalities directly under the Central Government so as to find out about the basie situation of community health service institutions across the country. The result indicated that by the end of 2002, the number of cities that had conducted community health service work reached 358. The coverage of community health services in cities of the prefecture level, areas under the jurisdiction of a city and cities of the county level was respectively 92. 1%, 80. 3% and 28.0% . 12 132 community health service institutions were set up in 2002, marking an increase of 31.6% as compared with 2001. The growth of community health services was fast and yet uneven in various regions. It is suggested that more efforts be made to strengthen community health services in medium-sized and small cities and improve the management of institutions and the system for statistical analysis of in-formation.

Objective To observe the therapeutic effect of Wenyang Huayu Sanjie Decoction ( WHSD) for the treatment of adenomyosis with the syndrome of blood deficiency and cold stagnation. Methods Seventy qualified patients were evenly randomized into observation group and control group. The control group was treated with Mirena intrauterine contraceptive device, and the observation group was treated with WHSD ( composed of Danggui Sini San, Wuzhuyu Shengjiang Tang, Shixiao San and Rhizoma Sparganii, Rhizoma Curcumae). The clinical outcomes included the menstrual blood volume, menstrual cycle, menstruation, degrees of dysmenorrhea, uterine volume, and serum CA125 level in the two groups before treatment and 3, 6 months after treatment. Results ( 1) After treatment for 6 months, the total effective rate of the observation group was 94.29%, significantly higher than 85.71% in the control group ( P<0.05). ( 2) After treatment, dysmenorrheal degrees, menstrual blood volume, menstrual cycle, menstruation, uterine volume, and serum CA125 level were improved in both groups ( P<0.05) , and the observation group had better effect on relieving dysmenorrhea, improving menstruation, and decreasing CA125 level than the control group ( P<0.05). ( 3) No obvious adverse reaction was found in the observation group, but most of the cases in the control group had menstrual disorder such as vaginal irregular bleeding and prolongation of menstruation. Conclusion WHSD has certain therapeutic effect on adenomyosis with the syndrome of blood deficiency and cold stagnation, and can also obviously improve the quality of life of the patients.

In order to study the angiogenesis in endometriosis, the samples of eutopic and ectopic endometria from patients with endometriosis were quantitatively analyzed by color morphometric image system (CMIS) for vascular surface area, and by examining endometrial blood vessel for microvessel density (MVD). The results showed that within each menstrual phase the vascular surface area and MVD were significantly higher in ectopic endometria with endometriosis than those in eutopic endometria with endometriosis or normal endometrium (P < 0.05). It is concluded that angiogenesis might be involved in the development of endometriosis.
