has been used as a traditional Chinese medicine for the treatment of various diseases. Triterpenoids and flavonoids from the plant have many beneficial effects and their chemical structures are modified in the gastrointestinal tract after oral administration. However, absorption of these triterpenoids and flavonoids still needs to be defined.

Objective: To explore the value of bronchoalveolar lavage as an emergency treatment for systemic lupus erythematosus (SLE) patients with concurrent diffuse alveolar hemorrhage (DAH).

Methods: A total of 21 SLE plus DAH patients were divided randomly into 2 groups. The patients in Group A received methylprednisolone 1000 mg/d for 3 days while those in Group B methylprednisolone 1000 mg/d for 3 days in combination with a bronchoalveolar lavage.

Objective: To study the genotype and gene characterization of measles wild viruses circulated in Jilin provinces, and to provide scientific evidences for setting down controlling and preventing strategy and measures.

Methods: 38 strains of measles virus isolated in 2001-2006 were genotyped by RT-PCR-RFLP, some strains of measles virus in Jilin province were chosen for the phylogenetic analysis and for the homology analysis of nucleotide and amino acid sequences.

Results: All the 38 strains of measles virus were identified as H1 genotype by RT-PCR-RFLP, and 29 strains of them were identified further as H1 a by sequence analysis.

Objective: A new simple RT-LAMP method was applied to detect measles virus nucleic acid and compared with nest-RT-PCR.

Methods: Compare the detection rate of the RT-LAMP method with that of nest-RT-PCR by detecting measles virus nucleic acid from measles virus and clinical samples.

Results: The nucleic acid positive rates of all 23 strains of measles virus are all 100% by the two methods.
