In China, the implementation of community health service shows that the prevention is an essential and important part of our national health system and is helpful to decrease the medical expenditure gradually. According to the data from Health Statistic Information Center of Ministry of Health in China, we calculated that the total health expenditure of China would be decreased 8000.0 million yuan only in 2001, among which, 1188.3 million, 1953.9 million and 4833.0 million yuan were respectively saved for the government budget, the society and resident if implementing the policy of community health service powerfully. And every outpatient can save 15. 46 yuan per time. By the quantitative analysis on the economic contribution of community health service, it can be proved that a great economic benefit could be gotten from the implementation of community health service.
The inhibitory mechanism of interferon-gamma (IFN-γ) on the fibroblasts from Tenon's capsule was studied. By using immunohistochemical SP method and pathological image system, the inhibitory effects of IFN-γ on the expression of transforming growth factor beta receptor I in thein vitro cultured fibroblasts from Tenon's capsule were quantitatively analyzed. The results showed that IFN-γ could reduce the expression of transforming growth factor beta receptor I in the fibroblasts with the following dose-effect relationship:Y=1937.5-134.2 Igx (r=−0.971,P<0.01). It was concluded that IFN-γ could inhibit the expression of transforming growth factor beta receptor I in the fibroblasts from Tenon's capsule. The modulation of the transforming growth factor beta receptor I expression by IFN-γ may be beneficial to the alleviation of the hyperplasia of scar after trabeculectomy.
In order to investigate the maxillary preprosthetic situation after oral tumor treatment and/or reconstructive surgery, based on the review of case history and the clinical records 47 cases were analyzed after oral tumor treatment and/or reconstruction, including residual maxillary bone, intermaxillary relationships, defection of maxilla and oral situation after radiation therapy. The results showed that the residual maxillary bone was useful for implantation in the front alveolar bone and zygoma area. The maxillary preprosthetic situation after tumor treatment and/or reconstructive surgery was difficult due to maxillary resection, intermaxillary relationships, unsuitable soft and hard tissue transfer and the irradiation. It is suggested that the maxillary preprosthetic situation after oral tumor treatment is getting worse not only due to maxillary resection and/or irradiation, but surprisingly also due to mandibular resection and or irradiation.
