Func.ional outc.me in c.nservatively treated non-displac.d sc.phoid frac.ures

Open Journal of c.inic.l Diagnostic. 2012年第4期2卷 66-69页

作者： Tessa Drijkoningen Frank J. P. Beeres Roderic. H. van Leerdam Daan Ootes Diana c. Grootendorst Marleen Otoide-Vree Steven J. Rhemrev Department of Trauma Surgery Medisch Centrum Haaglanden Hague Netherlands Landsteiner Instituut Medisch Centrum Haaglanden Hague Netherlands Marleen Otoide-Vree

Purpose: This study evaluated the func.ional outc.me after c.nservative treatment of non-displac.d sc.phoid frac.ures using an international validated outc.me sc.le (DASH). Methods and materials: Between 2005 and 2010, 60 patients with a non-displac.d sc.phoid frac.ure were inc.uded. When a patient visited the emergenc. department and was c.inic.lly suspec.ed of a sc.phoid frac.ure radiography was performed. If no frac.ure was diagnosed with this modality a c. or MRI-sc.n both in c.mbination with bonesc.ntigraphy was performed. Patients with sc.phoid frac.ures diagnosed with c./MRI and bonesc.ntigraphy were treated with a six-week sc.phoid forearm c.st. Within 1 year after c.st removal patients filled in the DASH questionnaire. Results: Sixty (80%) patients returned the DASH questionnaire at 12 months after treatment. Thirty-eight (63.3%) were male and the mean age was 35 (range 11 - 83). Forty-four (73.3%) patients had a mid-waist frac.ure of the sc.phoid, 13 (21.7%) had a frac.ure of the distal pole and three (0.05%) had a proximal frac.ure. Median DASH sc.re at one year after the trauma was 6 (range 3 - 15) for patients with a distal pole frac.ure and 5 (range 0 - 21.5) for mid-waist frac.ures (p = 0.7, table 2). For the three patients with a proximal sc.phoid frac.ure the DASH sc.res appeared higher and were 83, 82 and 30 respec.ively. c.nc.usion: c.nservative treatment for six weeks with a below the elbow c.st is suffic.ent for the majority of patients with an oc.ult distal or mid-waist sc.phoid frac.ure and results in a good func.ional outc.me ac.ording to the DASH questionnaire.

As a newly developed prec.sion tec.nology, c.sting-forging c.mplex near net forming proc.ss is utilized to produc. c.mplex c.mponents with a short lead time, low c.st and high prec.sion, thus to ac.elerate the response speed of the market and enhanc. the c.mpetitive power of produc.s. In this paper, the c.sting-forging c.mplex near net forming proc.ss of alternator c.aw pole was developed and investigated with a c.mbination of experimental and numeric.l simulation method. Qualified near net workpiec. was manufac.ured, mec.anic.l parameter and relative field information during the forming proc.ss was also obtained. While the alternator c.aw-pole is proc.ssed with this tec.nology, the forming forc. is small, the proc.ss is short and the quality of forgings is perfec.. Therefore, the c.mplex c.sting-forging near net forming proc.ss of c.aw-pole is an energy and material saving tec.nology, whic. will have a vast developing and applic.tion prospec. in the future.

该文提出一种考虑外扰动和饱和特性的开关磁阻直线电动机的自校正位置控制方法,利用自校正方法的参数自调整特点,克服因制造精度、饱和以及外扰动造成的模型不确定所带来的控制精度损失。该文中开关磁阻直线电动机采用单入单出的离散模型描述,利用回归最小二乘法估计参数,并应用极点配置自校正算法进行过程控制。仿真和试验结果证明该方法在参数估计、位置跟踪响应速度和在扰动下的鲁棒性等均有很好的效果。

Paraaortic.infrarenal lymphadenec.omy is indic.ted in patients with gynec.logic.tumors of high metastasising potential and c.n be done suc.essfully by laparosc.pic.approac.. Vasc.lar anomalies in this region are inc.dental findings during these approac.es and may inc.ease the surgic.l c.mplic.tion rate. In this study, we have doc.mented the frequenc. and pattern of the vasc.lar anomalies in paraaortic.region intraoperatively and on c.davers in an attempt to inc.ease surgic.l safety. A total of 86 c.nsec.tive patients underwent laparosc.pic.infrarenal paraaortic.lymphadenec.omy by a standardised tec.nique between 1st of January 2002 and 1st of Marc. 2004. Of the 86, 52 were primary c.rvic.l, 5 rec.rrent c.rvic.l, 14 endometrial, 14 early ovarian and 1 vulvar tumor with positive groin and pelvic.lymph nodes. In the same time, anatomic.l dissec.ions of the paraaortic.region on 18 c.davers were performed at the Institute of Anatomy. Arterial or venous abnormalities were identified in 30.2% (26/86) of patients by laparosc.py. The most frequent anomalies were related to atypic.l renal arteries (pole arteries- 9 patients) and an abnormal c.urse of lumbar veins direc.ly draining in the left renal vein (15 patients). In one of the patients, the c.mplete left renal vein went retroaortic.to the inferior vena c.va. In c.daveric.dissec.ions, vasc.lar anomalies were noted in 44.4% (8/18) whic. inc.uded variations in renal and lumbar vessels and ovarian vessels. Duplic.ted inferior vena c.va was the least c.mmon anomaly and was detec.ed in only one c.se. During laparosc.pic.paraaortic.inframesenteric.and infrarenal lymphadenec.omy, c.re must be taken bec.use of possible abnormalities in arterially and venous system to avoid massive hemorrhage, transfusion and c.nversion to laparotomy.

Introduc.ion: The elements and perc.ption of beauty vary between populations around the world. To obtain better results, surgic.l tec.niques should be planned based on anthropometric.c.arac.eristic. of the rac., loc.tion, and body mass index (BMI). Objec.ives: To determine whic. are the standard measurements and anatomic.l proportions of the breast in a healthy Mexic.n women population. Materials and Methods: Female Mexic.n volunteers between 20 and 60 years of age, without any history of breast illness or breast surgery were studied. Demographic.information and standard breast anthropometric.measurements were c.llec.ed manually by one of the authors. For the statistic.l analysis a Student-T test was performed, and the Pearson c.rrelation c.effic.ent was obtained using the latest version of SPSS software. Results: 78 volunteers were inc.uded in the analysis. Mean height, weight and BMI were 1.6 m, 68.9 Kg, and 26.6 Kg/m2 respec.ively. The mean anthropometric.values found were: Supra Sternal notc. to nipple distanc. (SSN:N) 22 c., Breast volume (BV) 372.6 c.3, Upper breast pole length (UBPL) 11 c., Lower Breast pole length (LBPL) 7.7 c., Midline to Nipple distanc. (ML:N) 10.2 c., Transverse diameter of the Nipple areola c.mplex (NAc.T) 4.1 c., Height of the Nipple Areola c.mplex (NAc.H) 4.1 c., Base of the breast (BB) 13.4 c., Upper pole to Lower pole Ratio (UPP:LPP) 58.9:41.1. A statistic.lly signific.nt differenc. between Right and left breast was not found. The UPP/ LPP ratio in our population is far different from what is c.nsidered internationally aesthetic.(45:55). A positive c.rrelation was found between weight/ BMI and SSN:N, BV, BB, ML:N and LBPL. Also between age and SSN:N, LBPL, BV and BB. c.nc.usion: This study sets the Anthropometric.grounds in Mexic.n population for an objec.ive individual patient analysis and c.mparison with the female population of this and other nations.

作者： c.j.Zhang c.Shao t.Y.c.ai

The adaptive c.ntrol issue of a c.ass of linear time-varying plants with uniformly bounded but piec.wise Lipsc.itz c.ntinuous parameters is c.sidered. A pole-plac.ment c.ntrol strategy whic. allows the plant to be with fast varying parameters is employed,under the c.ndition of the number of disc.ntinuities of the plant parameters being small on average .For the c.se where plant parameters are partially unknown ,an indirec. adaptive c.nrtol sc.eme is developed by c.mbining and *** addition,it is shown theoretic.lly that the c.osed-loop system is stable in .the bounded-input bounded -output sense.A simulation example is also given to show the applic.bility of the c.ntrol sc.eme.

采用Ｈ∞优化算法来实现电力系统稳定器（ＰＳＳ）的鲁棒控制设计。该方法采用了分子—分母双扰动表达形式、部分极点配置技术和一种新的加权函数选择方法，从而克服了某些传统ＰＳＳ设计方法中受到的限制。在将电力系统的高度非线性特性作为模型的“不确定性”处理后，设计出的控制器具有很好的鲁棒性。与传统设计方法的比较，证实了所设计的ＰＳＳ在较宽的系统运行范围内具有更好的阻尼性能。
