基于“同病异治”原则治疗类风湿性关节炎中药的研究进展

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。

目的：观察高良姜、大高良姜、红豆蔻黄酮类成分对胃溃疡寒证大鼠环核苷酸水平及交感神经-肾上腺轴的影响,探讨3味山姜属中药温热药性的物质基础。方法：采用灌服冰知母水煎液与15%冰乙酸制备大鼠胃溃疡寒证模型,以干姜姜辣素为阳性对照,采用酶联免疫吸附试验（ELISA）法测定腺苷酸环化酶（AC）、磷酸二酯酶2（PDE2）、环磷酸腺苷（cAMP）、环磷酸鸟苷（cGMP）、促肾上腺皮质激素（ACTH）、多巴胺β羟化酶（D-β-H）含量。结果：与空白组比较,胃溃疡寒证模型组大鼠胃组织AC、cAMP含量及cAMP/cGMP比值显著降低,PDE2含量显著升高（P<0.01）。与模型组比较,高良姜、大高良姜、红豆蔻高低剂量组大鼠胃组织AC含量升高;高良姜、大高良姜、红豆蔻高低剂量组大鼠胃组织PDE2含量显著降低,cAMP含量、cAMP/cGMP比值显著升高（P<0.01或P<0.05）。结论：3味山姜属中药黄酮类成分通过调节胃溃疡寒证大鼠环核苷酸水平从而促进交感神经-肾上腺轴功能活动的作用,也体现出黄酮类成分药性温热。     

银黄洗剂治疗下肢血栓性浅静脉炎的临床疗效观察

目的:观察银黄洗剂治疗下肢血栓性浅静脉炎的临床疗效。方法:将62例诊断为下肢血栓性浅静脉炎的患者随机分为对照组和观察组,各31例。对照组在常规治疗的基础上应用硫酸镁湿敷,观察组在常规治疗的基础上应用银黄洗剂湿敷,疗程均为10 d。比较两组患者临床症状评分(皮肤颜色、患肢肿胀、硬索结节及疼痛的评分)、相关实验室指标(超敏C反应蛋白及纤维蛋白原)的变化情况以及总有效率。结果:观察组总有效率90.32%,高于对照组的64.52%(P<0.05)。与治疗前比较,两组症状体征评分明显改善,超敏C反应蛋白及纤维蛋白原明显降低(P<0.05)。观察组在改善症状体征及降低炎性反应方面较对照组更明显(P<0.05),两组治疗后纤维蛋白原数值比较,差异无统计学意义(P>0.05)。结论:银黄洗剂治疗下肢血栓性浅静脉炎,可有效改善患者临床症状及降低炎性反应,明显提高临床疗效。     

保留下颌骨舌癌联合根治术后复发部位及其因素的分析

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。     

常温氧合血性心停搏液持续灌注心肌保护效应的实验研究

目的　采用随机对比的实验研究方法从测定心肌酶学、氧自由基代谢产物及心肌特异性蛋白几个方面来探讨冷晶体心停搏液间断灌注及常温氧合血性心停搏液连续灌注两种灌注方法的心肌保护效应。方法１４只犬随机分为①对照组：冷晶体心停搏液间断灌注;②实验组：常温氧合血性心停搏液连续灌注。采集不同时点的犬冠状静脉窦血为测定标本,测定心肌特异性酶ＣＫ－ＭＢ、心肌特异性钙蛋白Ｔ（ｃＴｎ－Ｔ）,氧自由基代谢产物丙二醛（ＭＤＡ）。结果对照组在主动脉开放后,ＣＫ－ＭＢ、ＭＤＡ、ｃＴｎ－Ｔ明显升高,实验组升高幅度较小。两组间比较有显著差异（Ｐ＜０．０１）。结论常温氧合血性心停搏液连续灌注,可以充分保证心肌在常温停跳期间的血供和氧供,避免了心肌缺血缺氧,明显地减轻了心肌缺血再灌注损伤,是一种非缺血性、比较理想的心肌保护方法。     

Improved survival in young women with breast cancer

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.

Strabismus and diplopia as complications after cataract surgery with IOL implantation

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.
