Clinical analysis of 129 Young patients with lung cancer / 中华全科医师杂志

Clinical data of 129 young pafienm with lung cancer were analyzed retrospectively.Adenocarcinoma was the main pathologic type of lung cancer(n=62,48.1%),followed by undifferentiated small cell carcinoma(n=35,27.1%),squamous carcinoma(n=20,15.5%).Forty four cases were misdiagnosed at first consultation with a misdiagnosis rate of 34.1%.To avoid misdiagnosis seems to be the key issue for improvement of prognosis in young patients with lung cancer.

Studies on the interaction between HSP90 and hepatitis E virus recombinant particle P239 / 中华微生物学和免疫学杂志

Objective To identify the protein interacting with hepatitis E virus(HEV) recombi-nant capsomeric particles(P239). Methods Protein interacting with HEV was analyzed by the pull-down, MALDI-TOF-MS, co-immunoprecipitation (Co-IP) and CONFOCAL. Results A protein interacting with HEV recombinant particle (P239) was identified as HSP90 by MALDI-TOF-MS. The interaction between HSP90 and P239 was further confirmed by Co-IP. The protein level and localization of HSP90 and P239 in HepG2 were detected. The total quantity of HSP90 didn't change, and the movement of HSP90 from plasma membrane to perinuclei region with P239 was observed. Conclusion HSP90 may play an important role in the trafficking of P239. It suggests that HSP90 participate in the transportation of HEV after infection, which may contribute to the prevention and control of the disease.
