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 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.

Objective To study the killing effect of hypocrellins B-photodynamic therapy (HB-PDT) for lung cancer cell line A549, to compare with that of hematoporphyrin derivative-photodynamic therapy (HpD -PDT), in order to define the superiority of HB-PDT in the therapy of lung cancer. Methods Lung cancer cell line A549 was used in the study. The cells were incubated in vitro with HB or HpD dissolved in DMEM in different concentrations, and then irradiated by copper vapor laser with mixed wavelength light under saturated light dose. Cell survival rate was respectively measured by MTT assay after 24 hours' incubation. According to cell survival curves after being cultured with different photosensitizers in different concentrations, the equation of each cell survival curve was plotted. Finally IC 50 (50% inhibition concentration) of each photosensitizer was derived. Results The results showed that HB-PDT had a strong killing effect on lung cancer cell. The IC 50 of HB was 33.82ng/ml for lung cancer cell, while the IC 50 of HpD was 1 316.88ng/ml, which was 38.94 fold of that of HB. Conclusions HB was a more effective photosensitizer than the photosensitizer HpD. HB-PDT had strong photodynamic killing effect on lung cancer cell line.

Syncope and epilepsy are common pediatric clinical symptoms and causes of paroxysmal loss of consciousness.They can be manifested as a sudden attack,transient and reversible loss of consciousness,easily leading to misdiagnosis in clinics.The etiology and pathogenesis of syncope and epilepsy are completely different,and the principle of treatment is also different.Therefore,in clinics,making an early diagnosis and differential diagnosis between syncope and epilepsy has an important significance to improve the treatment and the prognosis of the patients.
