[Reducing the Incidence of Back Pain in Post-Percutaneous Coronary Intervention Patients With Femoral Sheath].

Background & Problems: Patients undergoing percutaneous coronary interventions (PCIs) are restricted to bedrest and immobilization of the affected leg for sheath retention. These result in high incidences of back pain and emotional irritation, which may negatively affect cardiac rehabilitation. One-hundred percent of the post-transfemoral PCI patients in our unit had a back-pain score of 3 or higher, with an average pain score of 6.

[Genetic analysis of HAV strains isolated from patients with acute hepatitis in Hebei Shijiazhuang of China].

Objective: To characterize the hepatitis A virus (HAV) wild type strains circulating in Hebei Shijiazhuang of China during 2005-2007, to provide the bases for further investigation of the sources of HAV infection.

Methods: The VP1/P2A junction regions were detected by RT-PCR from HAV IgM positives serum samples during 2005 and 2007, the 34 RT-PCR positive samples were sequenced and subjected to phylogenetic analysis by Neighbor Joining (NJ) method.

Results: All the detected HAV strains were identified as sub-genotype I A, the homology of nucleotide sequence in the VP1-2A imation region ranged from 95%-100%, the amino acid sequences of HAV strains almost had no difference.
