Objective:To study the effect of magnetism-medicine bag navel therapy on the immunological function of mice with splenasthenic diarrhea.Method:Forty KUN MING mice were randomly divided into 4 groups:negative control group,splenasthenic diarrhea model group,magnetism-medicine bag navel therapy group,false magnetism-medicine bag navel therapy group.The index of thymus,the index of spleen and the cabon clear index(?)of cabon clear test of the mice were determined.Result:The mice spleen index,thymus index and the cabon clear index(?) of cabon clear test of the magnetism-medicine bag navel therapy group increased significantly than those of the splenasthenic diarrhea model group(P

OBJECTIVETo compare the effects of Atractylodes lancea from different producing area on collagen-induced arthritis (CIA) in rats.

METHODWistar rats were induced by type II bovine collagen. CIA rats were treated daily with oral administration of A. lancea from the geo-authentic and non-authentic producing area of Maoshan, Jiangsu province, and non-geo-authentic and non-authentic producing areas of Yingshan, Hubei province and Huayin, Shanxi province from day 7 after the day of the first immunization to day 35. Clinical symptoms as well as clinical scores and incidence were observed. All rats were sacrificed on day 35 after immunization to observe histopathologic and radiologic changes. Antibody to type II collagen in sera was measured by enzyme-linked immunosorbent assay (ELISA), the levels of pro-inflammatory cytokines tumor necrosis factor alpha (TNF-alpha), interleukin-1beta (IL-1beta), and interleukin-6 (IL-6) in sera and article-homogenated supernants by radiommunoassay, and inflammatory mediator of PGE2 in sera using ELISA.

RESULTA. lancea from Jiangsu province can ameliorate clinical symptom, reduce arthritis index and arthropathy of inflammatory joints, inhibit the production of IgG and IgM in sera, directly suppress the production of exogenous and endogenous cytokines of IL-1beta, TNFalpha and IL-6 and PGE2. A. lances from Hubei and Shanxi provinces can inhibit the production of IgM in sera, and A. lanceas from Hubei province also depress the production of IL-1beta in sera and IL-6 in supernants.

CONCLUSIONA. lancea from Jiangsu province is effective in CIA rats through inhibiting the production of pro-inflammatory cytokines and the inflammatory mediators.

OBJECTIVETo explore the expression and significance of miRNAs and Th17 related cytokines in patients with multiple myeloma (MM).

METHODSA total of 27 MM patients and 8 health controls were enrolled in this study. The expression of miR-15a/16,miR-34a,miR-194-2-192 cluster and miR-181a/b in bone marrow were detected by real-time quantitative PCR (qRT-PCR). Enzyme-linked immunosorbent assay (ELISA) was used to determine the levels of Th17 related cytokines interleukin-17 (IL-17), IL-21, IL-22, IL-23 and IL-27 in peripheral blood plasma. The role of miRNAs and Th17 related cytokines was analyzed in the development of MM.

RESULTSThe expression of miR-15a/16,miR-34a,miR-194-2-192 cluster in MM patients were significantly lower than those of the health controls, while miR-181a/b were exactly the reverse (P<0.05). The levels of IL-17, IL-21 and IL-27 were up-regulated in MM patients compared to health controls while IL-22 was down-regulated (P<0.05). There was no significant difference of IL-23 between the two groups. The levels of miRNAs and Th17 related cytokines had associated with ISS but not with some clinical parameters (such as gender, age, disease classification). Higher expression of IL-17, IL-21, IL-23, IL-27, miR-181a/b and lower expression of miR-15a/16,miR-34a,miR-194 and IL-22 were observed in the end stage than the early stage of MM patients (P<0.05). There was a significant correlation between miRNAs and Th17 related cytokines.

CONCLUSIONUp-regulated IL-17, IL-21 and IL-27 may potentially down-regulate the expression of several miRNAs in MM patients. Establishment of the relationship may be useful for understanding the pathogenesis of MM and for clinical diagnosis of the disease.
