Successful treatment of pancreatic schwannoma by enucleation: A case report

Rationale:Pancreatic schwannomas are extremely rare and are difficult to diagnose preoperatively. Over the past 50 years, only 96 cases of pancreatic schwannoma have been reported in English literature. Herein, we report a case of pancreatic schwannoma treated with enucleation.Patient concerns:A 66-year-old woman visited a local hospital due to ventosities. Ultrasonography and computed tomography revealed a pancreatic mass. She visited our hospital for further diagnosis and treatment.Diagnosis and interventions:Magnetic resonance imaging revealed a tumor in the pancreatic body, and a solid pseudopapillary tumor was considered preoperatively. During the surgery, a pancreatic mass was found growing in the pancreatic body and tail. A successful tumor enucleation was performed. The mass was 7 × 6 × 3 cm in size with a thin capsule. Pathological examination revealed that the tumor was mainly composed of spindle-shaped cells with a palisading arrangement and no atypia. Both hypercellular and hypocellular areas were visible. Immunohistochemical staining showed that protein S-100 was strongly positive. The tumor was diagnosed as a benign schwannoma originating from the pancreatic body and tail.Outcomes:Postoperatively, the patient showed good recovery. During the 24-month follow-up period, the patient remained well and free of complications.Lessons:Pancreatic schwannomas are extremely rare and difficult to diagnose using imaging examinations. Enucleation is a safe and efficacious treatment for exophytic pancreatic schwannomas.

超声造影与增强螺旋CT评估原发性肝癌非手术治疗的对比研究

目的:探讨超声造影在原发性肝癌非手术治疗评估中的价值.方法:对56例(64个病灶)经超声引导穿刺活检病理确诊的原发性肝癌患者进行非手术治疗.治疗后分别行超声造影和增强螺旋CT检查,以判断肿瘤的灭活程度,并对其判别能力进行比较.结果:超声造影发现46个病灶没有增强(46/64),18个病灶有部分增强(18/64).增强螺旋CT发现48个病灶没有增强(48/64),16个病灶有部分增强(16/64).与临床追踪结果比较,超声造影和增强螺旋CT对非手术治疗疗效判定的敏感性、特异性及准确率分别为94.4%,97.8%,96.9%和83.3%,97.8%,93.8%,差异有统计学意义(P＞0.05).结论:超声造影是判定非手术治疗原发性肝癌效果的一种敏感而有效的方法.对肝动脉插管栓塞化疗(TACE)疗效评估及少数血供不是特别丰富的病灶,超声造影具有较增强螺旋CT更重要的临床价值.

Experimental study of methane hydrate generation characteristics in the presence of GO and Re-GO

The industrial application of hydrate technology is greatly hindered by its slow generation rate, low gas storage rate, harsh generation conditions, and poor environmental friendliness of traditional additives. In this paper, the kinetic and thermodynamic promotion effects of graphene oxide (GO) and recovered graphene oxide (Re-GO) on methane hydrate in different systems were studied by the constant volume methods. The promotion mechanism was analyzed from the micro perspectives of molecular physical properties, interfacial reaction, and nucleation sites. It is found that GO has an excellent kinetic and thermodynamic promotion effect on CH₄ hydrate generation. After the recovery process, the thermodynamic effect of Re-GO is basically unchanged, and the kinetic promotion effect is slightly reduced. Furthermore, it is verified that the GO material itself does not have a memory effect in hydrate formation. The results show that GO is an excellent accelerator of CH₄ hydrate formation with high recovery value, which provides essential data and an experimental basis for the research and application of graphene oxide and hydrate technology in energy storage and cold storage.

GO can be recycled after use. GO and Re-GO have both kinetic and thermodynamic promoting effects. Re-GO basically has the same thermodynamic effect and slightly lower kinetic effect as GO. GO does not have the memory effect in hydrate formation.
