凤梅,,汪凤兰
中国公共卫生 , 2010, DOI: 10.11847/zgggws2010-26-10-52
Abstract: ?居家不出(housebound)作为导致卧床和痴呆的因素(1-2),最早由美国人Snellgrove在1963年提出,目前多数学者将其定义为:每周外出次数≤1次的状态(1)。找出老年人居家不出的影响因素,可预防及减少老年人卧床的发生,提高老年人生活质量,减轻社会负担。
未焊透缺陷深度对LY12铝合金搅拌摩擦焊焊缝电导率的影响
,,杨成刚,柯黎明
材料工程 , 2010,
Abstract: 采用涡流电导测量仪,测量了LY12铝合金搅拌摩擦焊垂直于焊缝方向的电导率分布及具有不同深度未焊透缺陷处焊缝的电导率。结果表明,焊缝中部电导率较高,母材电导率较低,存在一过渡区,各区的电导率变化与其组织变化有关。未焊透深度对焊缝电导率分布曲线有影响。当未焊透深度较小时,其焊缝中心电导率相对无缺陷时变化不大。当未焊透深度较大时,其焊缝中心电导率值急剧下降,且未焊透深度越大,电导率值越低。

Abstract: 摘要: 目的 探讨腹腔镜超声在辅助子宫肌瘤剔除术中的应用价值,为临床降低子宫肌瘤术后复发率提 供科学依据。方法 选取2011 年1 月-2014 年6 月在该院住院治疗的子宫肌瘤患者156 例,根据数字表法将 患者分为对照组和观察组,每组78 例,对照组患者给予常规的腹腔镜微创治疗,观察组患者给予腹腔镜超声 辅助微创治疗,比较两组患者一般治疗情况、术后残留和12 个月复发的情况、不同时间点的肌瘤个数和肌瘤 直径,分析子宫肌瘤的数目与残留与复发的关系。结果 两组患者手术时间、术中出血量、住院时间以及肛 门排气时间的差异均无统计学意义;观察组患者术后残留的比例以及12 个月内复发的比例明显低于对照组, 且差异具有统计学意义;观察组术后3、6、9 和12 个月的子宫肌瘤数目低于对照组;两组患者术后3 和6 个月子宫肌瘤最大直径的差异无统计学意义,观察组患者术后9 和12 个月的子宫肌瘤的最大直径明显低于对 照组,且差异具有统计学意义;随着患者子宫肌瘤数目的增多,术后的残余发生率和复发率明显提升,当子宫 肌瘤的数目≥ 10 个,残留率为100.0%,复发率为80.0%。结论 腹腔镜超声辅助微创手术应用于子宫肌瘤患者, 可以有效降低术后的残余率和复发率,值得临床推广。
Abstract: Objective To investigate the effect of laparoscopic ultrasonography assistance in minimally invasive surgery for uterine leiomyoma patients and provide scientific basis for reducing the recurrence rate of uterine leiomyoma. Methods 156 cases of uterine leiomyoma from January 2011 to June 2014 were divided into control group and observation group according to the digital table method, 78 cases in each. The control group were treated with conventional laparoscopic surgery, while the observation group with laparoscopic ultrasonography assistance, then compare the postoperative residue, recurrence in 12 months at different time points and the number of fibroids diameter, analyze the relationship between number of uterine muscle tumor and residual recurrence. Results There were no significant differences in operation time, blood loss, length of hospital stay and anal exhaust time between the two groups. The proportion of patients in the observation group and the recurrence rate within 12 months were significantly lower than those in the control group, the number of uterine leiomyomas in the observation group wassignificantly lower than that in the control group at 3 months, 6 months, 9 months and 12 months after operation. The patients in the two groups were followed up for 3 months and 6 months the maximum diameter of uterine leiomyoma was not statistically significant, the observation group 9 months and 12 months after the maximum diameter of uterine fibroids was significantly lower than the control group, and the difference was statistically significant; with the patient’s uterine muscle the number of residual tumor and the recurrence rate were significantly increased. When the number of uterine leiomyomas was 10 or more, the residual rate was 100.0% and the recurrence rate was 80.0%. Conclusion Laparoscopic ultrasonography assistance in minimally invasive surgery for patients with uterine fibroids can effectively reduce the postoperative residual rate and recurrence rate, worthy of clinical promotion.

Abstract: 对崎峰茶金矿废弃地破坏区自然恢复植被及周边未破坏区自然植被特征进行调查研究的基础上,结合生态学原理,为废弃地植被修复的植物材料和群落配置模式提供建议。植被调查采用样方法,研究地植被物种总计134种,隶属53科104属,均为乡土物种。其中破坏区自然恢复植被处于次生演替初期,总计物种55种;菊科、蔷薇科、蝶形花科、唇形科等优势科草本对不良生境具较强抗性和适应性。未破坏区自然林是植被修复的重要种质资源库,总计物种88种,与破坏区物种构成具较大差异;优势科为菊科、蔷薇科、毛茛科、桦木科等;乔、灌层优势种分布的海拔梯度格局较为显著,乔木层优势种为蒙古栎、山杨等,灌木层优势种为六道木、小花溲疏、毛榛、卵叶鼠李、山杏等。稳定度指数法评价筛选出的13个典型原生植物群落对破坏区植被恢复的群落配置具有一定借鉴意义。
Taking Qifengcha Gold Ore as research area,a thorough investigation on vegetation characteristics in the waste-rock yard and surrounding intact forest area was carried out to provide some strategic suggestions on the plant species selection and community collocation.Quadrat sampling method was adopted.The number of plant species in the research area was 134,belonging to 53 families and 104 genera,all were native species.The natural vegetation restoration in the destruction area had 55 species,those species from dominant families of Compositae,Rosaceae,Papilionaceae and Labiatae could resist and adapt to the barren soil condition well with higher restoration value.The intact forests had 88 species,much different from the destruction area in terms of species composition.The dominant families were Compositae,Rosaceae,Ranunculaceae,and Betulaceae,etc.In the intact forest area,the dominant species of tree layer and shrub layer showed different distribution patterns in different altitudes,with Quercus mongolica and Populus davidiana as dominant tree species,and Abelia biflora,Deutzia parviflora,Corylus mandshurica,Rhamnus bungeana,Armeniaca sibirica as dominant shrub species.Thirteen typical forest vegetation communities were selected out by stability degree index,which could be used as a reference to the community configuration in the human-induced vegetation restoration
