Splenic rupture is a common consequence of blunt abdominal trauma.Emergency splenectomy is indicated when conservative management is not effective.With better understanding of the immunologic function of the spleen,surgeons have begun to perform the splenic-preserving surgery.However,it is technical challenge to perform emergency laparoscopic partial splenectomy for patient with spleen rupture.A 15-year-old male patient suffered from gradeⅢspleen injury basing on the American association for the surgery of trauma splenic injury scale.Conservative treatment failed to success basing on the dramatically decreased hemoglobin level.During the laparoscopic exploration,we found that two individual ruptures were associated with the upper pole of spleen.An emergency laparoscopic partial splenectomy was successfully carried out.The operative time was approximate 150 min and the estimated blood loss was 200 m L.The post-operative course was uneventful and the patient was discharged on the 7th post-operative day.

Objective:To compare sleep-related outcomes in obstructive sleep apnea hypopnea syndrome (OSAHS) patients following base of tongue resection via robotic surgery and endoscopic midline glossectomy.Methods:This was a retrospective study.A total of 114 robotic and 37 endoscopic midline glossectomy surgeries were performed between July 2010 and April 2015 as part of single or multilevel surgery.Patients were excluded for indications other than sleep apnea or if complete sleep studies were not obtained.Thus,45 robotic and 16 endoscopic surgeries were included in the analysis.Results:In the robotic surgery group there were statistically significant improvements in AHI [(44.4 ± 22.6) events/h-(14.0 ± 3.0) events/h,P ＜ 0.001] Epworth Sleepiness Scale (12.3 ± 4.6 to 4.5 ± 2.9,P ＜ 0.001),and O2 nadir (82.0％ ± 6.1％ to 85.0％ ± 5.4％,P ＜ 0.001).In the endoscopic group there were also improvements in AHI (48.7 ± 30.2 to 27.4 ± 31.9,P =0.06),Epworth Sleepiness Scale (12.6 ± 5.5 to 8.3 ± 4.5,P =0.08),and O2 nadir (80.2％ ± 8.6％ to 82.7％ ± 6.5％,P =0.4).Surgical success rate was 75.6％ and 56.3％ in the robotic and endoscopic groups,respectively.Greater volume of tissue removed was predictive of surgical success in the robotic cases (10.3 vs.8.6 ml,P =0.02).Conclusions:Both robotic surgery and endoscopic techniques for tongue base reduction improve objective measures of sleep apnea.Greater success rates may be achieved with robotic surgery compared to traditional methods.

This paper investigates the partial anti-synchronization in a class of chaotic systems. Firstly, the existence of the partial anti-synchronization for the chaotic system is proved. By a systematic method including two algorithms, all solutions of the partial anti-synchronization for a given chaotic system are then derived, and physical controllers are designed. Finally, an illustrative example with numerical simulations is used to verify the validity and effectiveness of the theoretical results.

针对多项式拟合模型系数矩阵中部分元素是某一自变量的函数的特点,根据partial EIV模型的解算思想,将系数矩阵中自变量的函数作为随机元素提取,顾及泰勒展开的二阶项,由协方差传播律计算自变量函数的协因数阵进行平差解算。实验结果表明,系数矩阵的元素不再是单独的自变量时,使用该算法可以得到与已有非线性总体最小二乘方法相近的参数结果,从构造随机向量权阵的角度提供了一种新的解算方法。

Under partial trade credit,suppliers usually require retailers to pay a fraction of the purchase cost immediately when ordering and the remaining payment is deferred at the end of the sales period.Considering a supply chain consisting of a risk-neutral supplier and multiple loss-averse retailers,we develop models under partial trade credit.We analyze the optimal decisions of a supplier and retailers under decentralized decision-making.The study shows that there is a unique Nash equilibrium among the retailers,and the optimal total order quantity of retailers increases as the delayed payment ratio increases and as the degree of retailers'competition increases,but decreases with an increase in the loss aversion.Numerical studies are conducted to demonstrate the solution procedures and the effects of the parameters on decisions and profits.
