Chinese Journal of Traumatology 2013年第2期16卷 103-106页

作者： gu gui-shan LI Ying-hua YANG Chen Department of Bone and Joint First Hospital of Jilin University Changchun 130021 China Department of Nuclear Medicine First Hospital of Jilin University Changchun 130021 China

Objective： To introduce bipolar hemiarthroplasty with a two-step osteotomy technique and observe its clinical result for unstable intertrochanteric frac- tures in senile patients. Methods： Fifteen consecutive patients with unstable intertrochanteric fractures aged from 81 to 92 years with a mean of 85 years were treated in our hospital from August 2006 to October 2011 （Evans type III in 4 cases, Evans type IV in 11 cases）, who received bipolar hemiarthroplasty with a two-step osteotomy technique performed by a senior or- thopedic surgeon through posterior approach under general anesthesia. All cases were evaluated by Zuckerman func- tional recovery score （FRS） and operative risk assessment software 1, based on the patients＇ physical and laboratory examinations preoperatively. The duration and blood loss have been recorded. There were 4 male cases （4 hips） and 11 female cases （11 hips）. All prostheses consisted of Link SP II femoral stem and bipolar femoral head. All patients were followed up for more than 1 year. Results： The average preoperative FRS, predictive value of operative morbidity and mortality were 83.7 （81.7- 85.9）, 9.3% （7.3%- 15.0%） and 3.5% （2.3%-4.2%）, respectively. The average operation time was 50 minutes with a mean intraoperative blood loss of 310 ml. There were no operative or anesthetic complications or deaths within 30 days after operation. Sitting up was permitted 3 to 4 days, and partial weight beating was allowed 5 to 7 days after operation. The average FRS was 79.3 at 30 days and 84.9 at 1 year postoperatively. Three patients died of unrelated causes （one due to myocardial infarction and the others due to cerebral hemorrhage during at least one-year follow-up）. Conclusion： Bipolar hemiarthroplasty with a two-step osteotomy technique for unstable intertrochanteric fractures in the senile patients is a good choice for early ambulation and good hip function.

Postoperative mortality and morbidity in octogenarians and nonagenarians with hip fracture： an analysis of perioperative risk factors

引用

Chinese Journal of Traumatology 2011年第6期14卷 323-328页

作者： MA Ren-shi gu gui-shan HUANG Xu ZHU Dong ZHANG Yu LIMing YAO Hai-yu Department of Orthopaedics First Hospital of Jilin University Changchun 130021 China

Objective： To evaluate the role of high risk factors in octogenarians and nonagenarians with hip trauma, which may lead to excessive mortality and morbidity postoperatively. Methods： Fifty-four octogenarians and nonagenarians patients were enrolled in the study, receiving surgical repair of hip fracture in our hospital from January 2006 to January 2010. High risk factors were recorded preoperatively in detail. Complications and survival state were followed up by telephone for 2 years postoperatively. All the data were analyzed by Chi-square test with SPSS 13.0. Results： Twenty-six males （48.1%）, aged from 80 to 94 years with a mean age of 84.2 years, and twenty-eight females （51.9%）, aged from 80 to 95 years with a mean age of 83.4 years, were presented in the cohort study. The hip traumas were caused by daily slight injuries （52 cases） and car accidents （2 cases）, respectively. Twenty-eight patients （51.9%） with femoral neck fracture while 26 patients （48.1%） with intertrochanteric fracture were diagnosed through an anterior-posterior pelvic radiophotograph. In this series, 39 patients （72.2%） suffered from one or more comorbidities preoperatively. The morbidity was 48.1% and the major cause was urinary tract infection, while a significant difference was noted between females and males. The mortality was 20.4% with a predominant cause of acute renal failure. Conclusions： The gender should be considered as a critical high risk factor in octogenarians and nonagenarians with hip trauma postoperatively. Females are more likely to suffer complications postoperatively, which is especially obvious in senile patients over 80 years （P〈0.05）. Urinary tract infection is the most frequent complication after hip surgery, followed by low limb embolism and malnutrition. The mortality is dramatically greater in patients over 80 years old than those below, and major causes are acute renal failure, multiple organ dysfunction syndrome and mental deterioration.

Uncontacted tire explosion causing trauma to bilateral lower extremities： A case report

Chinese Journal of Traumatology 2017年第3期20卷 177-179页

作者： Ming-Yang Yu Yun Su Xiang-Jun Meng Bo-Wu Luan gui-shan gu Qiang Sun De-Wei Zhao Department of Traumatic Orthopedics Affiliated Zhongshan Hospital of Dalian University Dalian 116001 China Department of Ophthalmology Affiliated Zhongshan Hospital of Dalian University Dalian 116001 China Department of Discovery Biology GenScript USA Inc. Piscataway 08854 USA Department of Orthopedics First Hospital of Jilin University Changchun 130021 China Department of Orthopeclics Affiliated Zhongshan Hospital of Dalian University Dalian 118001 China

It is uncommon for tire explosion related injuries on the lower extremity. The bilateral lower extremities were injured by tire explosion when the patient was seated in a bus. She sustained an open fracture with partial bone loss in the right calcaneus （a comminuted fracture in the right ankle joint） and a closed comminuted fracture in the left tibia and fibula. This damage was caused by uncontacted tire explosion, thanks to a thick floor between the exploded tire and the patient＇s feet. This type of injury on lower extremity caused by uncontacted tire explosion was uncommon.

目的:探讨波长为532 nm半导体激光对体外培养骨肉瘤多药耐药细胞株(R-OS-732)增殖的影响。方法:实验分4个实验组和1个空白对照组。实验组在特定功率半导体激光功率下根据照射时间分为A、B、C和D组(输出功率为200 mW,照射时间分别为5、10、20和40 min),分别于照射后24 h及48 h进行观察。空白对照(E)组除不加激光照射外其他条件与实验组完全相同。采用MTT比色法观察R-OS-732细胞增殖情况,并通过光镜观察细胞形态学变化。结果:在532 nm波长、输出功率200 mW半导体激光照射条件下,A、B、C及D组与E组相比,细胞存活率明显降低,并有随照射剂量增加而加剧的趋势(P<0.05);光镜观察见细胞贴壁生长减少,细胞密度变小。结论:在一定波长、能量密度及照射时间的条件下,低能量半导体激光照射可导致体外培养骨肉瘤多药耐药细胞增殖受抑。
