自河北地区２６例格林－巴利综合征（ＧＢＳ）患者粪便中分离出７株脊髓灰质炎病毒（ＰＶ）ＩＩ型，分离阳性率为２６．９２％，同一地区脊髓灰质炎患者粪便ＰＶ分离阳性率为３３．１８％，ＰＶＩＩ型为４．１８％。健康人群ＰＶ携带率为９．９％，ＰＶＩＩ型为０．６６％。ＧＢＳ患者粪便ＰＶＩＩ型分离阳性率，既显著高于同一地区脊髓灰质炎患者粪便ＰＶＩＩ型分离阳性率（Ｘ￣２＝２０．８４，Ｐ＜Ｏ．０１），又显著高于健康人群ＰＶＩＩ携带率（Ｘ￣２＝２９．６２，Ｐ＜Ｏ．０１），１例ＣＢＳ患者脑脊液（ＣＳＦ中分离到１株ＰＶＩＩ型。５株ＰＶＩＩ型具有野毒株温敏特征。８株经聚合酶链反应鉴定提示与ＰＶＩＩ型Ｓａｂｉｎ株有部分共同核酸序列，推测属ＰＶＩＩ型重组株，可能与本地区部分ＧＢＳ发病有关。
Seven strains of poliovirus (PV) were isolated from feces of 26 patients with GBS in Hebei Province, with a positive rate of 26.92%, and positive stool PV separation in the same area of poliomyelitis The rate was 33.18% and the PVII type was 4.18%. The PV population carrying rate was 9.9% in healthy population and 0.66% in PVII. The positive rate of PVII-type separation in excrement of GBS patients was significantly higher than that of the PVII-type excretions isolated from polio patients in the same area (X ~ 2 = 20.84, P <0.01), but also significantly higher than that of healthy people (X ~ 2 = 29.62, P <0.01), one patient with cerebrospinal fluid of CBS (one PVII isolated from CSF and five PVII patients with wild-type virus, Identification tips and PVII Sabin strains share some common nucleic acid sequences, suggesting that PVII-type recombinant strains may be related to the local part of GBS pathogenesis.
