BACKGROUND Ovarian tumors are common gynecological diseases in children, and the most commonly seen ovarian tumors are germ cell tumors. Robotic surgery is the new access for children ovarian *** SUMMARY From June to October 2017, 4 children with ovarian tumors were admitted and treated in the Department of Pediatric Surgery of People’s Liberation Army General Hospital. The mean age, height, and weight of these patients were 7.5(1-13) years old, 123.75(71-164) cm, and 36.8(8.5-69.5) kg, respectively. Roboticassisted resection of ovarian tumors was performed for all 4 patients. The 3-port approach was used for robotic manipulation. The surgical procedures were as follows. After creation of the pneumoperitoneum, the robotic scope was placed to explore and find the left ovarian tumor. The trocars for robotic arms 1 and 2 were placed at the sites to the lower right and left of the port of the scope. The tumor capsule in the fallopian tube was incised, and the tumor was completely stripped by an electric hook along the junction of the tumor and the capsule. The resected tumor was completely removed using an endobag. The average docking time of the robotic system was 18.5 min, the average operative time was 120 min, and the average blood loss was 20 m L. No drainage tube was placed except in one patient with a mucinous tumor of the ovary. No fever, pelvic fluid, or intestinal obstruction was reported after surgery. No antibiotics were used during the perioperative period, and the average length of hospital stay after surgery was 3 *** Robotic-assisted resection of ovarian tumors is a simple, safe, and effective surgical procedure for selected patients.

背景:铁死亡是一种区别于凋亡、坏死等新型细胞程序性死亡的方式,主要由累积的脂质过氧化引起,已被证实参与蛛网膜下腔出血后的病理过程。黄芩素是一种铁螯合剂,能够抑制脂质过氧化反应,但其在蛛网膜下腔出血后早期脑损伤中缓解神经元铁死亡的作用仍未明确。目的:探讨黄芩素治疗蛛网膜下腔出血后对神经元铁死亡的影响及机制。方法:提取孕16-17 d C57BL/6L胎鼠大脑皮质神经元细胞,运用血红蛋白刺激原代神经元模拟体外蛛网膜下腔出血模型。采用CCK-8法检测5,15,25,50,100μmol/L黄芩素作用24 h后原代神经元细胞的活力,确定黄芩素的最适浓度。然后将原代神经元细胞分为对照组、血红蛋白组、血红蛋白+黄芩素组,利用试剂盒检测细胞内活性氧和丙二醛水平,RT-PCR检测铁死亡相关标记物PTGS2、SLC7A11、谷胱甘肽过氧化物酶4的mRNA表达;进一步将原代神经元细胞分为对照组、SLC7A11抑制剂Erastin组、血红蛋白组、血红蛋白+黄芩素组、血红蛋白+黄芩素+Erastin组,Western blot检测铁死亡相关标记物SLC7A11和谷胱甘肽过氧化物酶4的蛋白表达。结果与结论:(1)选取25μmol/L黄芩素作为后续实验浓度;(2)与血红蛋白组相比,血红蛋白+黄芩素组丙二醛和活性氧水平显著下降(P <0.05);(3)与血红蛋白组相比,血红蛋白+黄芩素组PTGS2的m RNA表达显著下降,SLC7A11和谷胱甘肽过氧化物酶4的m RNA表达显著升高(P <0.000 1);(4)SLC7A11抑制剂Erastin能在一定程度上逆转黄芩素改善的铁死亡作用(P <0.05);(5)结果表明,黄芩素可通过SLC7A11/GPX4通路缓解蛛网膜下腔出血后神经元细胞的铁死亡。

We explicitly compute the first and second cohomology groups of the SchrSdinger algebra S（1） with coefficients in the trivial module and the finite-dimensional irreducible modules. We also show that the first and second cohomology groups of S（1） with coefficients in the universal enveloping algebras U（S（1））（under the adjoint action） are infinite dimensional.

We report on a study of the molecular cloud S64 with observations at millimeter wavelengths of multiple molecular lines of CO isotopes. A weak outflow is found, and its physical parameters are estimated. The departure of the core of S64 from the S64 HII region indicates that there are still other star formation activities in that region.
