OBJECTIVETo explore lupus nephritis (LN) patients' monocyte chemotactic protein 1 (MCP-1) and urinary IP-10 (ulP-10) levels, the correlation between each clinical activity index and rheumatism syndrome, thereby proving objective evidence for microscopic typing of rheumatism syndrome.

METHODSTotally 60 LN patients were assigned to the rheumatism group (31 cases) and the non-rheumatism group (29 cases). Besides, 20 healthy volunteers were recruited as the normal control group. Clinical data and renal pathology were collected, and urinary levels of MCP-1 and IP-10 detected by ELISA. The correlation between rheumatism syndrome and each activity index as well as manifestations of clinical activities was comprehensively analyzed. Results (1) Patients in the rheumatism group were more liable to occur fever, serositis, edema, and hypertension (P<0.05). (2) Compared with the non-rheumatism group, patients in the rheumatism group exhibited much higher levels of 24 h protein quantification and blood urea nitrogen, higher levels of uMCP-1 and ulP-10. Microscopic hematuria, anti-ds-DNA, anti-Sm, the positive rate of AnuA, scores of SLEDAI and BILAG were higher in the rheumatism group than in the non-rheumatism group (P<0.05). Levels of plasma albumin and complement C3 were lower in the rheumatism group than in the non-rheumatism group (P<0.05). (3) The average activity index (AI) of the renal pathology was higher in the rheumatism group than in the non-rheumatism group. The most frequent pathological type of rheumatism group was type IV of LN.

CONCLUSIONSMore severe renal damage and immune abnormality occurred in LN patients of rheumatism syndrome. Rheumatism syndrome is closely correlated to clinical activity indices.

Objective To study the SRSF2 mutations in acute myeloid leukemia (AML) patients by using high-resolution melting analysis (HRMA). Methods PCR-HRMA analysis was performed to screen SRSF2 mutations in 140 cases with AML, and the direct DNA sequencing was used to confirm the HRMA results. Results Five percent (7/140) of AML patients were found with heterozygous SRSF2 mutations, including one case of P95R mutation, two case of P95L mutation, and four cases of P95H mutation, the above mutations were confirmed by direct DNA sequencing. The maximal sensitivity of HRMA in detecting SRSF2 mutation was close to 10%. There were no difference in gender, age and blood parameters among cases with or without SRSF2 mutations (P > 0.05). The overall survival (OS) of patients with SRSF2 mutations was inferior to those without SRSF2 mutations in AML patients (P=0.016). Conclusions HRMA analysis was a convenient, rapid, specific, high-throughput technique for scanning of SRSF2 gene mutations in AML patients. SRSF2 mutation may predict the adverse prognosis in AML patients.
