肛肠疾病手术前后肛管直肠压力测定的应用

目的:探讨肛肠疾病手术前后肛管直肠压力测定的应用。方法:将2018年5月-2019年5月在上海市松江区方塔中医医院及上海中医药大学附属曙光医院肛肠科行手术治疗的826例肛肠疾病患者作为研究对象,其中,选择性痔上黏膜吻合术246例、单纯外剥内扎术115例、外剥内扎结合内痔套扎术(Automatic Ligation of Hemorrhoids,RPH)153例、低位肛瘘切除术177例、高位肛瘘切开挂线术135例,分别于术前及术后1个月测定肛管直肠压力。结果:选择性痔上黏膜吻合术后直肠静息压、肛管静息压明显低于术前,肛管舒张压高于术前(P<0.05),但肛管最大收缩压与术前相比无明显差异(P>0.05);单纯外剥内扎术术后直肠静息压、肛管静息压明显低于术前,肛管舒张压、肛管最大收缩压明显高于术前(P<0.05);外剥内扎结合内痔套扎术术后直肠静息压、肛管静息压明显低于术前,肛管舒张压、肛管最大收缩压明显高于术前(P<0.05);低位肛瘘切除术术后直肠静息压、肛管静息压、肛管舒张压均高于术前(P<0.05),而肛管最大收缩压与术前相比无明显差异(P>0.05);高位肛瘘切开挂线术术后直肠静息压高于术前,肛管静息压、肛管舒张压低于术前(P<0.05),而与肛管最大收缩压术前相比无明显差异(P>0.05)。结论:肛肠疾病手术前后肛管直肠压力测定的应用效果显著,能准确判断手术效果及患者恢复情况,为医师的进一步诊治奠定了良好基础。     

Pediatric Inpatient Headache Therapy: What is Available

Status migrainosus is defined by the international classification of headache disorders (ICHD) criteria as a debilitating migraine lasting more then 72 hours. The epidemiology of status migrainosus is still unknown in adult and children, and frequently underdiagnosed. Children and adolescents often end up in the emergency room with an intractable headache that failed outpatient therapy. Six to seven percent of these children do not respond to acute infusion therapy and require hospitalization. It is imperative that more aggressive therapy is considered when patients are affected by a severe intractable headache to prevent further disability and returning the child to baseline activity. Multiple therapies are available for adults and children. Studies for acute therapy in the emergency room are available in adults and pediatric groups. Small studies are available for inpatient therapy in children and, along with available therapies for children and adolescents, are described in this review. A review of the literature shows growing evidence regarding the use of dihydroergotamine intravenously once patients are hospitalized. Effectiveness and safety have been proven in the last decades in adults and small studies in the pediatric populations.     

Rabs and axonal regeneration

Membrane trafficking processes are presumably vital for axonal regeneration after injury, but mechanistic understanding in this regard has been sparse. A recent loss-of-function screen had been carried out for factors important for axonal regeneration by cultured cortical neurons and the results suggested that the activity of a number of Rab GTPases might act to restrict axonal regeneration. A loss of Rab27b, in particular, is shown to enhance axonal regeneration in vitro, as well as in C. elegans and mouse central nervous system injury models in vivo. Possible mechanisms underlying this new finding, which has important academic and translational implication, are discussed.     

多原发结直肠癌的临床特征和预后

目的探讨多原发结直肠癌的临床特征和预后。方法回顾性分析南京医科大学第一附属医院2013年1月至2018年12月收治的42例多原发结直肠癌患者的临床资料,对其临床病理特征、诊治及预后进行总结。结果符合多原发结直肠癌诊断的患者42例,占同期收治的所有结直肠癌患者的1.20%(42/3499),病理类型以腺癌为主。其中,同时性多原发癌32例,年龄38~86岁,中位年龄66岁,共发现73处结直肠癌灶,多位于近端结肠、乙状结肠及直肠;共检出淋巴结527枚,阳性10枚(1.9%),淋巴结阳性患者占同时性多原发癌的37.5%(12/32);27例为双原发癌,3例为三原发癌,2例为五原发癌;1、3年总生存率分别为83.75%和74.38%。异时性多原发癌10例,年龄33~86岁,第一癌多位于直肠和乙状结肠区域,第二癌多位于升结肠区域;共检出淋巴结276枚,阳性率12.3%(34枚),1、3年总生存率分别为100.00%和66.67%。结论多原发结直肠癌在临床上不少见,其分布有一定规律。临床中应引起重视,提高早期诊断率。应早期手术治疗以提高患者的生存率。
