假体隆乳术后并发症的防治

目的探讨乳房假体隆乳术后并发症产生的相关因素及预防方法。方法对198例患者乳房假体隆乳术后1~17年出现的并发症进行分析,阐述防治措施,针对不同情况进行相应的处理。结果本组198例患者,其中92例患者随访半年至1年,除Ⅲ°包膜挛缩患者术后仍出现Ⅱ~Ⅲ°包膜挛缩外(包膜松解术后3例,包膜切除术后4例),余患者对治疗效果满意。结论乳房假体隆乳术后出现的并发症,多数是可以预防和治疗的,只要术中操作规范,对并发症及早准确的处理,是提高手术效果,减少并发症发生的有效方法。     

44Sacral extracorporeal magnetic stimulation is an effective treatment for pelvic floor dyssynergia; Comparative study with biofeedback therapy

Background: Recent development of extracorporeal magnetic stimulation (ECMS) which uses current‐changing magnetic fields allows the induction of electrical stimulation in the desired deep tissue. Recent study showed the sacral nerve stimulation reduces corticoanal excitability that may play a functional role in anal continence mechanisms. Preliminary study shows that ECMS of sacral nerve can modify pelvic floor function and expel rectal balloon in patients with pelvic floor dyssynergia (PFD). Aims: To evaluate the effect of ECMS compared with biofeedback therapy (BF) in patients with PFD. Methods and Materials: Thirty‐eight patients who fulfilled Rome II criteria for PFD by colon transit time and anorectal function tests, were randomly treated with 8 sessions of ECMS (2/weeks; n = 19) at prone position or BF (2/weeks; n = 19) at sitting position. Stimulation parameters were set at 50–80% of maximum intensity, 10 and 50 Hz frequency, 3 s burst length with 3 and 6 s off using arm‐typed stimulator (BioCom‐1000, Mcube Co., Korea). Symptom scores for constipation with/without anorectal function test were repeatedly measured after each treatment. Response was defined as 50% or more decreased symptom score after treatment (partial response: 30–50%, poor: <30%). Results: Fifteen patients (age 49.1 ± 13.4 years, mean ± SD; 4 men) completed 8 session of BF and 14 patients (54.5 ± 17.6 years, 3 men) completed 8 session of ECMS. Four patients of BF group discontinued treatment due to unsatisfactory therapeutic effect (n = 1) and withdrew consent (n = 3) and 5 patients of ECMS group discontinued treatment because of same reasons (n = 1, 4). Total symptom scores were significantly decreased after treatment of 8 session in both treatment groups (13.4 ± 6.6 vs. 4.3 ± 4.0 for BF, p = 0.009; 14.9 ± 5.6 vs. 3.4 ± 4.0 for ECMS, p < 0.001). Bowel movements per week were also significantly increased after treatment in both groups (median 2 vs. 7 for BF, p = 0.035; median 2 vs. 7 for ECMS, p = 0.008). Thirteen out of 15 patients showed response in BF group and 12 out of 14 showed good response in ECMS group. No adverse effects in both groups. Conclusions: ECMS is as effective as BF for the treatment of PFD. Long‐term effect of ECMS for the patients with pelvic floor dyssynergia need to be evaluated in the near future.     

浅谈药剂学的备课

由于长期从事药剂学的教学工作，在备教材、备学生这2个重要方面积累了一些经验：寻找教材中存在的问题，然后适当地处理教材；找准学生真实的学习起点，为学生设计自主学习的方式，以便于更好地实施教学。     

急性重复性缺氧小鼠脑组织中儿茶酚胺类神经递质含量变化的研究

用高效液相-电化学检测器测定急性重复性缺氧小鼠脑组织中DOPA、DA、NE和Ep等儿茶酚胺类物质的含量。结果发现:与空白对照组(A组)比较,缺氧1次的实验对照组(B组)及急性重复缺氧4次实验组(C组),随缺氧次数增加,小鼠脑组织中的DA含量显着上升(P<0.01),NE、DOPA含量明显降低(P<0.05或<0.01);A组与急性重复4次缺氧后饲养2d的实验对照组(D组)小鼠脑组织中儿茶酚胺类含量接近,没有统计学意义(P=23.77).结果提示脑组织中儿茶酚胺类物质可能参与急性重复缺氧小鼠的耐缺氧能力的形成,而且是一个可逆的快反应。

上海地区女性生殖道人乳头瘤病毒感染的检测

应用地高辛甙元标记人乳头瘤病毒(HPV)-6,11,16和18探针,通过核酸杂交法检测上海地区女性患者HPV的感染。计活检组织标本128例,阴道脱落细胞130例,同时取样34例。斑点杂交结果表明活检组织中四种类型HPV的总阳性率:宫颈癌44％,宫颈间变66.7％,有间变史28.6％,外阴尖锐湿疣63％和慢性宫颈炎5.6％。阴道脱落细胞的各阳性率与之相近,同时取样的检测符合率为91.2％。Southern转移杂交结果提示:宫颈癌以HPV-16型为主,尖锐湿疣中的HPV为6和11型     

Recent microsurgical advances in China

For more than two decades, microsurgery has been developed, practiced, and refined in China. For the most part, this has taken place independent of a parallel process in the Western World. Only until recent years has there been some communication from China regarding this microsurgical experience. The authors believe that there is much yet to be learned from the wealth of Chinese experience in microsurgery, just as Chinese surgeons have gained valuable information from the West. The authors reviewed the microsurgical literature in China from 1983 to 1986, and present here what we regard to be of particular interest to American microsurgeons, including the areas of digital reconstruction, replantation, flap transfer and transposition, and microsurgical techniques and patient management. Some historical background in the development of Chinese microsurgery is also provided.     

胃癌单克隆抗体-丝裂霉素C结合物的制备及其细胞毒特征

作者报道胃癌单克隆抗体MG11-丝裂霉素C(MMC)结合物的制备及其对肿瘤细胞的杀伤作用。首先用戊二酐处理MMC,于MMC上引入羧基,MMC衍生物与N羟基琥珀酰亚胺及2,2′-二环已基碳二亚胺反应,得到MMC活性酯,后者与抗体反应将MMC引入抗体中。经测定,每克分子抗体中引入约6～7克分子药物,结合物对人胃癌细胞KATⅢ具有较强的选择性杀伤作用,在0.56μg/ml水平(药物浓度)对肿瘤细胞杀伤牢达60％,优于游离药物(51％)及无关抗体结合物(9.3％),提示选用的胃癌单抗对MMC具有较好的导向作用。
