The results of topical application of 13-cis-retinoic acid on basal cell carcinoma. A correlation of the clinical effect with histopathological examination and serum retinol level

A group of 50 patients with basal cell carcinoma of the face was treated by 13-cis-retinoic acid. The treatment resulted in diminution of the tumors. Complete regression was observed in 4 cases. Histological examination revealed necrosis of cancer cells and mononuclear infiltration into the treated tumors. In the group with weak clinical and histological reaction to the treatment all basal cell carcinomas were of adenoid type. A better effect was observed in the group with lower serum retinol level. This treatment method seems to be supplementary to surgery in prevention of the tumor recurrence.     

50例甲状腺癌的临床病理分析

甲状腺癌是临床和病理易于误诊的恶性瘤之一,高分化甲状腺癌与甲状腺腺瘤很难鉴别,甲状腺癌的组织学分类和病理诊断标准至今尚未统一。本文根据50例甲状腺癌的临床病理分析,参阅有关文献,对甲状腺癌的诊断标准、鉴别诊断和地方性甲状腺肿与癌的关系进行讨论。     

国产奎硫平合并舒必利治疗难治性精神分裂症

目的:了解舒必利合并国产奎硫平(启维)治疗难治性精神分裂症的疗效和安全性。方法:26例符合CCMD-Ⅲ精神分裂症诊断标准且临床判断属于难治性病人,予舒必利合并奎硫平治疗,疗程8周,分别在治疗前及治疗后进行阳性与阴性症状量表(PANSS)和不良反应状量表(TESS)评定。结果:合并治疗8周后总有效率65.3%。PANSS阳性、阴性及一般精神病理评分于治疗前后均有显著差异(P<0.01)。TESS总分治疗前后无显著差异(P>0.05)。副反应主要为肌张力增高、失眠、体重增加、静坐不能。结论:对于舒必利治疗反应不佳的难治性精神分裂症病人合并奎硫平治疗仍可取得较好的临床效果,安全性较高,耐受性及依从性好,可作为临床治疗难治性病人的方法之一。     

Antiproliferative Activity Against MCF‐7 Breast Cancer Cells by Diamino‐Triazaspirodiene Antifolates

Two triazaspirodienes, having similar phenoxy propyloxy side chain, were identified as potent mammalian dihydrofolate reductase inhibitors; one having a 6,5‐spiro bicyclic ring system (IC₅₀ = 2.3 nm ) and the other a 6,6‐spiro bicyclic system (IC₅₀ = 6.9 nm ). They also showed more than 50% antiproliferative activity against the MCF‐7 breast cancer cells at 20 μm . This study demonstrated the potential lead of the diamino‐triazaspirodienes in anticancer chemotherapeutical agents’ discovery.     

Pain and faulty breathing: a pilot study

The purpose of this pilot study was to observe both relaxed and deep breathing patterns in a convenience sample to determine the incidence of normal versus faulty patterns of respiration. These observations were then combined with respondent answers to a survey on pain history to determine if there is any correlation between faulty breathing and musculo-skeletal pain patterns. If such a correlation can be made, then we propose that clinicians working with chronic pain patients may have improved outcomes if they address and correct faulty breathing patterns. Based on this study, it is suggested to include the evaluation and treatment of faulty respiration in the rehabilitation of chronic musculo-skeletal conditions, most notably cervical pain.     

戊二醛交联提高胶原/壳聚糖真皮支架抗细胞收缩能力的研究

目的 应用交联处理的胶原支架,来减缓其降解过多、易收缩变形、机械性能不足等缺点.方法 采用冷冻-冻干法构建胶原/壳聚糖多孔支架,并通过戊二醛交联构建具有良好抗细胞收缩稳定性和细胞相容性的胶原支架.通过测定不同培养时间各类支架的尺寸变化,研究了戊二醛交联对支架抗细胞收缩能力的影响.结果 戊二醛交联后的胶原/壳聚糖支架未见明显收缩,其细胞活性也始终高于干热交联支架.结论 戊二醛能有效地提高胶原基支架的抗细胞收缩能力,并保持其良好的生物相容性.     

乳腺癌改良根治术后自帖式敷料包扎刀口35例临床观察

目的:探讨乳腺癌改良根治术后自帖式敷料包扎刀口的临床效果。方法:将70例乳腺癌改良根治术患者随机分为两组,对创面不同包扎方式进行对比。结果:自帖式敷帖对术后创面包扎并发症少于传统绷带加压包扎方式。结论:自帖式敷帖包扎乳腺癌改良根治术后创面,能预防切口并发症的发生。     

尿石症住院患者1100例分析

目的了解近年来尿石症住院患者情况的变化。方法对1998年~2003年间的尿石症住院患者1100例进行分析。结果本组中,肾结石251例(22.8%)、输尿管结石742例(67.5%)、膀胱结石97例(8.8%)、尿道结石10例(0.9%)。上、下尿路结石的比例为9.28∶1。高钙尿患者27例(13.0%)、高钙血症91例(9.1%)、高尿酸血症167例(17.8%)。结石成分分析结果:草酸钙168例(62.7%);磷酸钙59例(22.0%);尿酸及尿酸盐25例(9.3%);磷酸镁铵10例(3.7%);碳酸盐5例(1.7%);胱氨酸1例(0.4%)。治疗:ESWL658例(59.8%)、肾切开取石术35例、肾切除术6例、输尿管切开取石术92例(占8.4%)、输尿管镜加气压弹道碎石52例(4.7%)、膀胱切开取石53例(其中前列腺摘除术加膀胱切开取石术26例);膀胱镜加气压弹道碎石20例;前列腺电切术加气压弹道碎石7例;膀胱镜加大力钳碎石术9例。尿道切开取石术1例;经尿道镜取石术2例;尿道镜加气压弹道碎石3例。结论本组尿石症患者以上尿路结石为主,含钙结石占绝大多数。尽管微创手术的普遍开展,ESWL仍不失为一种创伤小、效果好的治疗方法。
