我国胃癌发病率高．规范化根治手术是目前治疗胃癌的主要方法。胃癌术后并发症、尤其是一些特殊并发症的发生，直接影响患者的预后，甚至造成病死率的上升。但这些特殊并发症发生率较低，医务工作者常因认识不足而延误诊疗。这些特殊并发症包括：（1）Petersen疝：为Roux—en—Y消化道重建后Roux袢与横结肠系膜的间隙形成的腹内疝，较为罕见，其可以迅速导致坏疽性肠梗阻。由于发生率较低，临床症状无特异性，临床往往不够重视，故后果十分严重。一旦诊断应立刻进行急诊手术。建议术中常规关闭Petersen间隙，以避免Petersen疝的发生。（2）淋巴漏：亦称乳糜漏。由于乳糜池是腹腔内广泛的淋巴管网络向膈肌角逐渐集中而成．故术中清扫淋巴结时易破坏周围淋巴网络而导致。术中使用超声刀可以在一定程度上降低淋巴漏风险。如果术中发现淋巴漏．可及时给予缝扎处理。治疗包括全肠外营养、内环境维持和补充白蛋白以及尝试性夹管观察。（3）十二指肠残端瘘：是胃大部切除术后影响患者恢复及导致死亡的严重并发症之一。术中对于十二指肠残端的正确处理，是预防十二指肠残端瘘的关键因素之一，建议术中常规行十二指肠残端荷包包埋。该并发症的处置关键在于及早获得正确诊断并采取有效的止血措施。（4）Roux．Y肠袢血供障碍：主要预防原则为术中注意肠管边缘血管弓的血供。（5）空肠残端大荷包导致吻合口梗阻：为远端胃癌根治术后行Roux-en—Y吻合术时．抵钉座置入残胃，将吻合器从远端空肠残端置入行胃空肠吻合，最后关闭残端，予以大荷包包埋．其包埋的空肠残端可疝人胃腔导致内疝并引发吻合口梗阻。我们建议采取间断交锁缝合并将残端固定于胃壁，可以避免该并发症的发生。

In the process of tire production, vulcanization process is the last process and core process in the total production. The vulcanization process becomes the main bottleneck of the whole tire production process because of the process’s long manufacture time, manufacture centralizing, energy sources large consume. Its plan quality is the key function of improving the utilization of vulcanization equipments and reducing the production cost. Production planning simulating system for vulcanization process based on heuristic algorithm was developed on the basis of studying planning strategy. The system integrates production planning, adjusting production starting time, adjusting the number of devices, inserting orders and withdrawing orders. The software system was tested by online data. Results show that the planning method can quickly workout the optimal production planning of vulcanization. The method will lay the firm groundwork for application to production process in the future.

The development of flexible supercapacitors(FSCs) capable of operating at high temperatures is crucial for expanding the application areas and operating conditions of supercapacitors. Gel polymer electrolytes and electrode materials stand as two key components that significantly impact the efficacy of hightemperature-tolerant FSCs(HT-FSCs). They should not only exhibit high electrochemical performance and excellent flexibility, but also withstand intense thermal stress. Considerable efforts have been devoted to enhancing their thermal stability while maintaining high electrochemical and mechanical performance. In this review, the fundamentals of HT-FSCs are outlined. A comprehensive overview of state-of-the-art progress and achievements in HT-FSCs, with a focus on thermally stable gel polymer electrolytes and electrode materials is provided. Finally, challenges and future perspectives regarding HT-FSCs are discussed, alongside strategies for elevating operational temperatures and *** review offers both theoretical foundations and practical guidelines for designing and manufacturing HT-FSCs, further promoting their widespread adoption across diverse fields.
