类风湿性关节炎是一种常见的慢性自身免疫性复杂疾病, 病因尚不明确, 治疗困难, 国内常以传统中医药手段将其辨证分型, 遵循“同病异治”的原则对其进行治疗。中医药辨证治疗类风湿性关节炎历史悠久, 效果显著, 同时中药方剂多靶点、多成分的特点使其更有效的缓解各自适应证患者的炎症症状。近年来传统中医药与西医的关联日渐加深, 西医技术与手段在中药治疗 RA 上的广泛应用, 不仅使 RA 不同证型的差异更加清晰, 中医辨病更加准确, 更在针对类风湿性关节炎适应证的中药方剂在临床、药效、生物学与治疗机制方面的研究取得了较大进展。文章基于中医“同病异治” “辨证分型”的原则, 对治疗类风湿性关节炎代表方剂与其研究进展进行综述。 相似文献

保留下颌骨舌癌联合根治术后复发部位及其因素的分析 总被引:4,自引:0,他引:4
作者报道68例行保留下颌骨舌癌联合根治术病例,其中术后复发23例,复发率为33.8%。在这23例中,其复发部位为:局部复发15例,对侧颈淋巴结转移7例,肝转移1例。这表明术后局部复发病例数最多,占65.2%(15/23)。此类复发病例再无拯救手术机会、预后极差。本文还着重分析了术后复发因素。认为术后复发与肿瘤原发部位及原发灶病变范围有关。 相似文献

Improved survival in young women with breast cancer 总被引:3,自引:0,他引:3

Background: Young age has been hypothesized to be an adverse prognostic factor for women with breast cancer. This association, based on historical data, may not reflect recent advances in breast cancer management.
Methods: A retrospective study was conducted of all women age 30 or younger who underwent definitive operation at our institution for primary operable breast carcinoma during one of two consecutive 20-year periods (1950–1969 or 1970–1989). All cancers were restaged according to current staging criteria. Actuarial survival and recurrence-free survival rates from the two patient eras were compared with each other and with published statistics for older breast cancer patients.
Results: Eligibility criteria were met by 81 women from the 1950–1969 era and 146 women from the 1970–1989 era. Histologic diagnoses, tumor sizes, incidence of axillary nodal metastases, number of positive nodes, and American Joint Committee on Cancer stage at presentation were similarly distributed in the two eras. Despite these similarities, improved survival (p=0.009) was observed in the later era. Local recurrences were also more common (p<0.05) in the later era in association with less extensive resections. These local recurrences had an adverse impact on recurrence-free survival in the later era, but no concomitant decrease in overall survival was observed. Node-positive patients who received chemotherapy demonstrated a trend toward improved survival (p=0.06) compared with node-positive patients who did not. Survival for patients in the later era was similar to that for older women as reported in other published series.
Conclusions: The stage of presentation of breast cancer in women 30 years or younger appears unchanged from prior decades, but survival has improved in association with the use of less extensive surgical resections and the introduction of cytotoxic chemotherapy. With current treatment, primary operable breast cancer in young women appears to have a similar prognosis to breast cancer in older women.Results of this study were presented at the 47th Annual Cancer Symposium of The Society of Surgical Oncology, Houston, Texas, March 17–20, 1994, and was judged Best Clinical Paper in the Resident/Fellow Essay Contest. 相似文献

Summary
In our Department of Orthoptics we have seen an increasing number of patients suffering from diplopia after cataract surgery
with IOL implantation. Between 1993 and 1997 the total number of patients with this problem was 24 (2.7 % of all patients,
mean age 71 years, age range 38–88). We addressed the question of whether there is a common pattern of motility dysfunction.
Methods: After evaluation of the clinical history and the basic ophthalmological findings the following parameters were examined:
binocular function (Bagolini test), squint angles (Maddox cross), ocular motility.
Results: The 24 patients could be divided up into three groups. Group 1 consisted of 9 patients (mean age 82 years, range 64–88) who
complained about diplopia because of strabismus incomitans with vertical deviation and restricted motility on the first day
after surgery. In 8 of the 9 patients strabismus surgery was done. Group II consisted of 10 patients (mean age 66 years, range
38–77) who noticed diplopia and strabismus within 7 days after surgery. We found various kinds of heterotropia. Seven of these
patients were operated on and two had a prism correction. Group III consisted of 5 patients (mean age 67 years, range 61–78).
Their already known strabismus paralyticus or concomitans deteriorated, leading to diplopia in some cases. All patients in
this group were operated on.
Discussion: For group I we believe that retro-, para- or peribulbar anesthesia caused the motility dysfunction. In groups II and III
it is unlikely that local anesthesia had a causative role. The prolonged disruption of binocular vision and the abrupt change
in the sensory situation after the cataract operation with lens implantation may be the leading causes for strabismus or deterioration
of a preexisting strabism, respectively.
Conclusions: These patients need a subtil meticulous diagnostic work-up and follow-up because of the possibility of early surgical therapy,
which has a good prognosis. Evaluation of binocular vision and eye movements prior to cataract surgery appears to be helpful
for later strabismic surgery.
