Deletion of Krüppel-like factor-4 promotes axonal regeneration in mammals

Axonal regeneration plays an important role in functional recovery after nervous system damage. However, after axonal injury in mammals, regeneration is often poor. The deletion of Krüppel-like factor-4 (Klf4) has been shown to promote axonal regeneration in retinal ganglion cells. However, the effects of Klf4 deletion on the corticospinal tract and peripheral nervous system are unknown. In this study, using a mouse model of sciatic nerve injury, we show that the expression of Klf4 in dorsal root ganglion sensory neurons was significantly reduced after peripheral axotomy, suggesting that the regeneration of the sciatic nerve is associated with Klf4. In vitro, dorsal root ganglion sensory neurons with Klf4 knockout exhibited significantly enhanced axonal regeneration. Furthermore, the regeneration of the sciatic nerve was enhanced in vivo following Klf4 knockout. Finally, AAV-Cre virus was used to knockout the Klf4 gene in the cortex. The deletion of Klf4 enhanced regeneration of the corticospinal tract in mice with spinal cord injury. Together, our findings suggest that regulating KLF4 activity in neurons is a potential strategy for promoting axonal regeneration and functional recovery after nervous system injury. This study was approved by the Animal Ethics Committee at Soochow University, China (approval No. SUDA20200316A01).

胃癌D2根治术后大出血的临床分析

目的总结分析胃癌D2根治术后发生大出血的原因及治疗方法并探讨其对生存预后的影响。方法回顾性分析广东省中医院2012年1月至2016年3月258例行胃癌D2根治术患者的临床资料,根据术后是否发生大出血分为出血组和非出血组。结果14例患者(5.4%)术后发生大出血;吻合口出血、十二指肠残端瘘或破裂是出血的主要原因;二次手术和胃镜止血是主要治疗措施。两组的短期总生存期有统计学意义(1年:P=0.017,3年:P=0.011)。结论吻合口出血、十二指肠残端瘘或破裂是胃癌D2根治术后出血的主要原因,及时诊断和治疗能有效降低病死率。胃癌D2根治术后大出血会降低患者的短期总生存期。     

孕期抗病毒治疗结合标准阻断措施对乙型肝炎高病毒载量孕妇所生婴儿母婴传播阻断的影响

目的分析乙型肝炎(乙肝)病毒(Hepatitis B virus,HBV)高载量孕妇孕期HBV脱氧核糖核酸(HBV desoxyribonucleic acid,HBV-DNA)水平和HBVe抗原(HBV e antigen,HBeAg)阳性率以及孕期抗病毒治疗结合标准阻断措施对其所生婴儿母婴传播阻断失败率的影响。方法通过医院信息系统收集HBV-DNA高载量(≥2×10^6IU/mL)孕妇血清学检测结果、抗病毒药物使用等信息,描述HBV-DNA载量和HBeAg阳性率;对HBV-DNA高载量孕妇所生婴儿进行乙肝疫苗(Hepatitis B vaccine,HepB)和乙肝免疫球蛋白(Hepatitis B immunoglobulin,HBIG)联合免疫,在完成第3剂HepB后7月龄-2岁对乙肝表面抗原和HBV-DNA进行随访检测,分析母婴传播阻断失败率。结果共纳入1822名HBV-DNA高载量孕妇,接受、未接受抗病毒治疗分别占75.19%、24.81%。孕妇妊娠期、分娩前HBV-DNA≥1.0×10^8IU/mL比例分别为68.10%(933/1370)、0.15%(2/1370)(χ^2=2692.27,P<0.0001)。接受抗病毒治疗组妊娠期、分娩前HBeAg阳性率分别为96.53%(1001/1037)、96.16%(1251/1301)(χ^2=0.23,P=0.635),未接受抗病毒治疗组妊娠期、分娩前HBeAg阳性率分别为97.70%(298/305)、96.98%(417/430)(χ^2=0.36,P=0.550)。两组HepB和HBIG联合免疫后母婴传播阻断失败率分别为0.42%(3/714)、6.67%(14/210)(χ^2=31.69,P<0.0001)。结论孕妇HBV-DNA高载量以≥1.0×10^8IU/mL为主,孕期抗病毒治疗可显著降低孕妇HBV-DNA载量,结合HepB和HBIG联合免疫可显著降低其所生婴儿HBV母婴传播阻断失败率。
