Hospital entrustment will incur cultural conflicts,which calls for cultural integration as the best means to ease such frictions and conflicts between two hospitals of cultural difference.Renmin Hospital of Wuhan University (Hubei general hospital)directly hosted Hanchuan people's hospital,and implemented the president responsibility system under the leadership of the management committee.By means of cultural integration to reshape Hanchuan hospital culture,Hubei general hospital has rebuilt the latter's culture.Such reshaping features the following:development as the core,scientific management as the breakthrough,employees as the center,technology upgrade as the basis,and patients service as the direction.Cultural integration has furthered development of the hospital entrusted,and turned frictions and conflicts into infiltration and integration.As a result,Hanchuan hospital is upgraded in general in terms of management and service quality.

Porcine endogenous retroviruses (PERV) can infect human cell in vitro, which raised widely concerns re-garding the transmission of PERV to xenograft recipients. It's essential to establish a method for detection of PERV.3 pairs of primers were synthesized according to the sequence of gag, pol and env gene of PERV. Polymerase chainreaction (PCR) and reverse transcription PCR (RT-PCR) assays were performed for detection of PERV provirusDNA and PERV specific mRNA. The results showed that provirus DNA and mRNA of PERV existed and expressedin all 4 tested cell lines. The sizes of amplified fragments are identical with the predicted. These methods may be suit-able for monitoring PERV in other cells or tissue.
