消炎痛治疗宫内放环后出血

积极治疗节育手术并发症是搞好计划生育的一个重要环节。月经异常是宫内放置节育环的主要并发症，也是节育环停止使用的主要原因。近几年来本人采用消炎痛治疗官内放环后月经异常，取得了良好的效果。     

DTF降茶氟剂降茶氟初步研究

目的探讨DTF制剂降茶氟效果。方法在不同制茶方法程序中加入DTF制剂观察其降氟效果。结果在冲泡或煮沸(1.0g茶叶,200ml水量)沏茶中,0.2gDTF可使茶氟降低约60%,使茶水氟浓度由2.0～4.0mg/L降到1.0mg/L左右,茶液色、味、pH值无改变。结论DTF是1种有效的降茶氟剂。     

采血者针刺伤的调查及危险因素分析

针刺伤在采血工作中经常发生，其危害大，后果严重，一般情况下还没有引起人们足够的重视。我国是肝炎的高流行区，近年来艾滋病在我国的发病率呈倍增的趋势。血液污染的针刺伤是导致血站采血人员发生血源性传染病最主要的职业因素。作者从实际工作出发，收集相关资料，系统的阐述了针刺伤的发生因素及预防措施等，并结合相关理论提出了一系列的措施和建议。     

Differential diagnosis of leg ulcers

In Germany about 0.7 % of the adult population have a chronic leg ulcer. Although chronic venous insufficiency accounts for at least 80 % of all chronic leg ulcers, knowledge of the relevant differential diagnostic considerations is of crucial importance, in particular for patients who are refractory to therapy. In addition to vascular disease, other causes include neuropathic, metabolic, hematologic and exogenous factors as well as neoplasias, infections, drugs, genetic defects and some primary skin disorders. For the long‐term successful treatment of patients with chronic leg ulcers, it is necessary to identify all relevant factors, in order to enable a pathogenesis‐oriented, interdisciplinary therapeutic approach.     

初次吸毒者与复吸者戒毒期间生活质量比较

目的:了解包头市初次吸毒者与复吸者戒毒期间的生活质量。方法:用QOL-DA2.0量表对戒毒人员的生活质量进行调查。结果:初次吸毒者与复吸者各纬度进行t检验显示躯体功能纬度(t=10.51)、心理功能纬度(t=5.94)、症状及毒副作用纬度(t=6.41)、社会功能纬度(t=10.47)和总分(t=10.48)均有统计学意义(P<0.001),表明戒毒期间初次吸毒者的生活质量高于复吸者。结论:在戒毒期间初次吸毒者的生活质量较复吸者易改善。     

Basic fibroblast growth factor and epidermal growth factor reverse impaired ulcer healing of the rabbit oral mucosa

BACKGROUND: The therapies for refractory ulcers on the oral mucosa are symptomatic and very unsatisfactory. We hypothesized that application of growth factors might be able to achieve successful remission of the lesion. We evaluated the effects of systemic administration and topical application of epidermal growth factor (EGF) and basic fibroblast growth factor (bFGF) on impaired wound healing of ulcers in the rabbit gingiva. METHODS: Almost uniform round ulcers could be created on the gingiva of the rabbits by chemical injury with acetic acid. When the submandibular glands were removed or i.v. injection of cisplatin (CDDP) and peplomycin sulfate was performed before ulcer formation, healing of the ulcers took longer than in untreated rabbits. To ascertain whether or not human EGF and bFGF affect rabbit cells, we first examined the effects of EGF and bFGF on the proliferation of the cells derived from rabbit gingiva. We then applied EGF or bFGF in these impaired healing models. RESULTS: EGF and bFGF promoted proliferation of the fibroblasts, and EGF also promoted proliferation of the keratinocytes isolated from gingival tissue of rabbits in vitro. Systemic injections of EGF and bFGF in rabbits, which had their submandibular glands removed, and topical application of bFGF accelerated healing of ulcers created in rabbits injected with CDDP and peplomycin sulfate. The ability of bFGF to promote the healing of ulcers was much greater than that of EGF. CONCLUSION: Basic FGF may be effective for refractory oral mucosal lesions.     

六经气津互化论

气与津皆生于水谷,气生于水,水化于气,津即为水。由于气津互化的密切关系,故任何一方的改变,都会影响到另一方,即所谓水化于气,亦能病气;气生于水,亦能病水。因此,太阳经气可概括为两大功能,即卫外和气化,是由气津互化而体现的;阳明气津之间,表现为相互制约;少阳经的气津互化,关系到少阳气机的条达舒畅及三焦水道的通调运使;太阴脾气的健旺,可使津液化生有源;少阴心肾精血充沛,滋养有时,才可使心肾之气化生有源;而厥阴之气的条达顺畅,又可维持津液代谢的平衡状态。     

Gonadotropins mediate DNA synthesis and protection from spontaneous cell death in human ovarian surface epithelium

Gonadotropins have been implicated in the development of epithelial ovarian cancers. These tumors are derived from ovarian surface epithelium (OSE). The purpose of this study was to determine the effects of these hormones on DNA synthesis and spontaneous cell death in primary cultures of OSE and three immortalized OSE cultures. Primary cultures of OSE cells were generated from the ovaries of women with benign disease. The effects of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) on DNA synthesis and cell death were determined using [(3)H]thymidine incorporation and JAM assays. Significant inductions of DNA synthesis were demonstrated with LH in 4/12 (33%) primary cultures of OSE and 2/3 OSE cell lines and with FSH in 4/11 (36%) primary cultures of OSE and 2/3 OSE cell lines. A significant protection from cell death was also observed in the presence of FSH in 2/4 primary cultures of OSE and 1/3 OSE cell lines and in the presence of LH in 1/4 primary cultures of OSE and 2/3 OSE cell lines. The results indicate that while gonadotropins have the potential to induce cell proliferation and protect from cell death in OSE cells in vitro, their effects are variable in OSE cells from different women.
