A case of a 47-year-old female patient who had a severe headache for 2 days was reported. Spontaneous subarachnoid hemorrhage (SAH, hunt-Hess classification Ⅱ level)-anterior communicating aneurysm rupture was diagnosed by brain CT and digital subtraction angiography (DSA) examination.Intravascular interventional aneurysm embolization was performed, and the patient appeared progressive limb weakness 5 days after operation. Physical examination revealed grade Ⅱ upper limb muscle strength and grade Ⅰ lower limb muscle strength. The muscle tone of the extremities was decreased,and the tendon reflex disappeared. The pinprick pain was decreased below the double wrist joints and the ankle joints. After neuroelectrophysiology test and cerebrospinal fluid assay, the patient was diagnosed as Guillain-Barré syndrome associated with subarachnoid hemorrhagic aneurysm embolization.

Objective To characterize 16S rRNA methylase encoding genes associated with aminoglycoaides resistance, gene cassettes of class Ⅰ integrons of the multidrug-resistant Acinetobctcter spp. The sixty one Acinetobacter isolates were collected at the Second Hospital of Shanxi Medical Uni versity from July, 2007 to May, 2008. Methods Species identification was confirmed by sequence analysis of the blaOXA-51-like gene and 16S-23S rRNA gene space-region. Antimierobial susceptibility tests were performed by agar dilution method. 16S rRNA methylaae encoding genes and gene cassettes associated with integrons were amplified by PCR method. Results Among the sixty one strains, there were fifty five of Acinetobacter baumannii, three genospecies 3TU, one 13TU, one Aeinetobaeter ealcoacetieus, and one Aeinetobaeter haemolytieus. Forty eight isolates showed high-level resistance to three aminoglyeosides, including amikaein, tobramyein and gentamicin. The armA gene was found in 47 isolates and all isolates were negative for rmtA, rmtB, rmtC and rmtD genes. The Intl gene was found in 27 isolates. The gene cassettes contained arr-3, accA4,ctacCI ,catB8, aadA1 or dfrA12 genes. According to the PFGE DNA patterns, 5 distinct clones of armA-pasitive strains were identified. Clone A and Clone B were the dominant clones, widely distributed among different divisions. Condnsions 16S rRNA methylase encoding gene (armA) distributed widely in muhidrug-resistant Acinetobacter spp. The armA gene is not located in class Ⅰintegron. The class Ⅰ integron carries multiple resistant genes associated with aminoglycosides and chloramphenieol resistance.PFGE analysis suggests that armA-pesitive strains are widely spread in our hospitaL Effective infection control measure should be conducted in order to control the outbreak of resistant bacteria.

Objective To study the adenovirus infection and popular features in hospitalized respira-tory infection children of Qingdao area. Methods A total of 6 820 cases of respiratory infection from March 2011 to February 2014 in our hospital were enrolled,the average age was 5 years and 2 months old. Their ve-nous serums were collected on the first day of hospitalization,adenovirus IgM was monitored by indirect im-munofluorescence application. The adenovirus-positive rates of cases between different age groups, seasons and diseases were observed. Results Adenovirus were positive in 1 043 children,the rate was 15. 29%. The positive rate of young children group(1-3 years old) was 16. 92%,which was highest,there was statistic difference between young children group and other age groups(χ2 =12. 50,P<0. 05). Adenovirus infection rates were upward in recent years,the infection rates of winter and spring were higher than those of summer and fall,and there were significant differences between them(χ2 =28. 89,P <0. 05). The positive rate of AdV-IgM in children with severe respiratory tract infection was higher[19. 90%(877/4 408)]than that of the children with mild infection[12. 27%(296/2 412)](χ2 =64. 25,P<0. 05). Conclusion In recent years, adenovirus infection rate in Qingdao hospitalized respiratory infection children was rising,the infection rates in winter and spring were high,young children were the most vulnerable populations. The positive rate of ade-novirus infection in children with severe respiratory tract infection is higher than that of the children with mild respiratory tract infection.
