Comparative StudyTreatment of lower urethral calculi with extracorporeal shock-wave lithotripsy and pneumatic ureteroscopic lithotripsy: a comparison of effectiveness and complications.
To determine the efficacy and incidence of complications of extracorporeal shock-wave lithotripsy (ESWL) compared with pneumatic ureteroscopic lithotripsy (URSL) in the treatment of lower uretheral calculi. ⋯ For the management of lower ureteric calculi, ESWL provides a non-invasive, simple and safe option, and URSL has a higher stone evacuation rate but causes ureter perforation more frequently than ESWL does. Both ESWL and URSL have their respective advantages. It is recommended, however, that URSL be extensively developed for better treatment efficacy, given that the operator has an adequate technical background.

Association between HLA-DQA1, -DQB1 gene polymorphisms and susceptibility to asthma in northern Chinese subjects.
Human leukocyte antigen (HLA) class II genes, especially HLA-DQ genes, which are highly polymorphic, have been thought to be candidate loci for the etiology of asthma, and shown to be involved in antigenic presentation. This study was conducted to investigate whether susceptibility or resistance to asthma is associated with HLA-DQA1 and DQB1 genes polymorphism. ⋯ HLA-DQA1 * 0104 allele and HLA-DQB1 * 0201 allele were implicated in susceptibility to asthma and atopy, HLA-DQA1 * 0301 allele and HLA-DQB1 * 0301 might be protective factor against asthma. Asthma and atopy are multifactorial disorders, HLA-DQA1 and DQB1 genes are involved in the regulation of immune specific response to common allergen.

Establishment of a fluorescent polymerase chain reaction method for the detection of the SARS-associated coronavirus and its clinical application.
To establish a fluorescent polymerase chain reaction (F-PCR) method for detecting the coronavirus related to severe acute respiratory syndrome (SARS) and to evaluate its value for clinical application. ⋯ The F-PCR method established may be a rapid, accurate and efficient way for screening and for the early diagnosis of SARS patients.
