Partial mastectomy with axillary lymph node dissection and radiotherapy as a new treatment modality of breast cancer (I).

This is the first preliminary report among two consecutive papers. Partial mastectomy(PM), axillary lymph node dissection(AD) and radiotherapy (RT) were performed on seventeen operable breast cancer patients who had been admitted from April 1991 to March 1992 to the department of surgery, Yongdong Severance Hospital for improved cosmetic appearance and better survival rate. Of seventeen patients, 47% were T1 lesion and 76% were stage I and II. Extensive intraductal component(EIC) within or around the tumor was also analyzed. Twenty nine per cent of the patients were EIC positive. The mean number of axillary lymph nodes was 21.5 after PM with AD and 20.5 after mastectomy. For radiotherapy, 4,500 rad was delivered to the breast parenchyma and 1,600 rad of boost to the primary tumor site using the electron beam method after surgery. All patients have since been living well without any local recurrence and were satisfied with breast preservation for the one-year follow-up period. We concluded that the PM, AD and RT can be another surgical treatment modality of breast cancer. A longer follow-up data will be followed on the second paper.

用PCR—RFLP和16SrDNA指纹图法分析幽门螺杆菌基因型

本文建立了PCR－RFLP和16srDNA指纹图法．对19株幽门螺杆菌（HP）进行基因型分析：HP尿素酶C基因的PCR扩增产物．分别用HindⅢ、HaeⅢ、AluⅠ酶切，结果显示：每个酶均将19株HP分为3种RFLP图谱．综合HindⅢ，HaeⅢ和AluⅠ酶切结果，19株HP分为10个酶切带型；PCR扩增HP标准株16SrRNA基因，地高辛标记制备550bp探针，19株HPDNA分别经HaeⅢ和EcoRⅠ酶切、电泳后，通过Southern杂交获16SrDNA指纹图，结果显示：HaeⅢ酶切分为14个杂交带型，EcoRⅠ酶切19株HP杂交带型均不同。本实验表明：上述两种方法重复性好，分群力高，可准确有效地对HP作出鉴定并将其分型。19株HP株间存在基因型差异。     

149例围产儿死亡原因分析

目的：探讨围产儿死亡原因及降低围产儿死亡率的措施。方法：对1994年1月－2001年12月在我院住院分娩的149例死亡围产儿的临床资料进行回顾性分析。结果：围产儿死亡率为22．74‰，死胎率为9．77‰，死产率为3．36‰，早期新生儿死亡率为9．62‰，占42．28％。围产儿死亡原因：缺氧占47．65％，早产占21．15％，出生缺陷占12．08％。结论：加强孕期保健、规范系统产前检查及监护、积极预防治疗妊娠并发症、防治早产、实施正确的新生儿窒息复苏方法、建立NICU等是降低围产儿死亡率的重要环节。     

纸板加压垫法治疗第五跖骨基底骨折113例临床分析

本文报告我院应用纸板加压垫法治疗第五跖骨基底骨折113例，优良率达92.9%。本组无不愈合病例，对治疗要点和骨折分类进行了讨论，提出二类三度分型方法。用于指导治疗和估计预后，作者认为本病治疗不当可留有不同程度后遗症，应当重视其治疗。     

微创手术治疗高血压脑出血

目的 探讨微创手术治疗高血压脑出血的临床疗效。方法 132例高血压脑出血分成微创手术组(68例)和传统开颅手术组(64例)，分析两组手术的特点和手术时机，比较两组手术治疗的疗效。结果 微创组术后GOS良好23例、中残24例、重残9例、植物生存3例、死亡9例；传统组术GOS良好16例、中残15例、重残12例、植物生存6例、死亡15例。两组超早期或早期手术均有良好的预后，而微创组效果更佳。结论 微创手术治疗高血压脑出血能明显提高临床疗效，降低病死率。

甘蓝复合果蔬汁的稳定性

单一的稳定剂并不能解决甘蓝复合果蔬汁的稳定性问题,而多种稳定剂的稳定效果较好,为此挑选出较好的3种稳定剂,对其进行不同比例的复配,观察一段时间的相对粘度及浊度变化,发现两种稳定剂的复配就能达到稳定的效果,最佳添加量(质量分数)为果胶0.07%,黄原胶0 03%.     

Clinical utility of trapezius muscle studies in the evaluation of amyotrophic lateral sclerosis.

Needle electromyography (EMG) and determining the motor evoked potential (MEP) of the genioglossus (tongue) are difficult to perform in evaluation of the craniobulbar region in patients with amyotrophic lateral sclerosis (ALS). Needle EMG and MEP determination in the upper trapezius were carried out in 17 consecutive ALS patients. The needle EMG parameters recorded included abnormal spontaneous activity and motor unit action potential morphology. An upper motor neuron lesion was presumed when either response to cortical stimulation was absent, or the central conduction time was delayed (>mean + 2 SD). Of the 12 patients with limb-onset ALS, using needle EMG, 11 were found to have abnormalities in the upper trapezius, and only five in the tongue. Three of the six patients with isolated limb involvement had abnormal MEP findings. In conclusion, electrophysiological studies of the upper trapezius are useful in ALS patients without bulbar symptoms.
