The Expression of CD40/CD40L in MM Patients and Its Significance to the Prognosis of MM Patients / 中国实验血液学杂志

OBJECTIVE@#To explore the expression of CD40/CD40L in multiple myeloma(MM) patients and its influence on prognosis.@*METHODS@#Thirty patients with MM treated in Cangzhou People's Hospital from May 2016 to June 2017 were selected and divided into MM group, then 30 healthy people with a physical examination in our hospital at the same time were selected as the normal group. The serum CD40/CD40L levels of the patients in the two groups was detected by flow cytometry, and its correlation with the lymphocyte population, pathological grade and prognostic significance of MM patients was anaysis.@*RESULTS@#The expression of CD40 in serum of the patients in MM group was significantly higher than those in normal group (P0.05). The levels of CD40 and CD40L in the patients before and after chemotherapy showed no difference(P>0.05). The levels of Ts and NK cells in the patients of MM group were lower than those in normal group (P0.05). The CD40 level was correlated with the serum total B lymphocyte level of the patients in MM group (r=0.877, P=0.005). There was a correlation with CD40L and Th cells in the serum of MM patients (r=-0.783, P=0.035). The expression of serum CD40 in the patients at phase III-IV was higher than those of the patients at phase I-II, the levels of serum CD40L in MM patients at different periods showed no significant difference(P>0.05). The survival rate of MM patients with high CD40 expression was lower than that of MM patients with low CD40 expression (χ@*CONCLUSION@#The increasing of CD40 level in MM patients is related to the pathological grade of the patients. Chemotherapy can reduce the level of CD40. The increasing of CD40 is an important factor for the poor prognosis of MM patients. CD40L level is not meaningful for MM treatment and prognosis.

Analysis on mechanisms and medication rules of herbal prescriptions for gout caused by heat-damp accumulation syndrome based on data mining and network pharmacology / 中国中药杂志

To mine the medication rules of herbal prescriptions for gout caused by heat-damp accumulation syndrome, and explore the possible mechanism of the core herbs, we collected the relevant literature of gout caused by heat-damp accumulation syndrome in CNKI, medication rules of herbal prescriptions are analyzed by using TCMISS(V2.5) software, and the compatibility of core drugs and new prescriptions were mined.KEGG pathway analysis was performed by BATMAN-TCM, an online analysis tool, and the potential signaling pathways of core drugs compatibility to treat gout caused by heat-damp accumulation syndrome were revealed. The results showed that six core drugs and three new prescriptions were found out of the 136 prescriptions. The core compatibility herbs in clinical treament of gout caused by heat-damp accumulation syndrome, Phellodendri Chinrnsis Cortex, Achyranthis Bidentatae Radix and Achyranthis Bidentatae Radix, which potential signaling pathways were purine metabolic pathway and neura activity ligand receptor interaction signaling pathway. Therefore, for gout caused by heat-damp accumulation syndrome, the mainly used therapies of TCM were clearing heat and drying dampness,inducing diuresis for removing edema, dispeling wind and eliminating dampness. The mechnisms of core compatibility herbs may be achieved through the intervention of purine metabolic pathway and neural activity ligand receptor interaction signaling pathway.

Effects of agkistrodon in different dosage forms on collagen-induced arthritis in rats / 中国结合医学杂志

<p><b>OBJECTIVE</b>To determine the effective dosage and formulation of agkistrodon in collagen-induced arthritis (CIA) rats.</p><p><b>METHODS</b>CIA was induced by injection of collagen in complete/incomplete Freund's adjuvant. Agkistrodon decoction, agkistrodon powder, and agkistrodon wine were administered daily starting from the onset of arthritis. Paw swelling degree was measured by using a volume-measuring instrument every 7 days after primary immunization. Arthritis index was measured and calculated using the "five scoring method" every 7 days. The levels of serum interleukin-1ß (IL-1ß) and type II collagen IgG antibodies were detected by enzyme-linked immunosorbent assay. Finally, all ankles were removed, and X-ray radiography was performed with In-vivo Imaging System FX. Samples were counterstained with hematoxylin and eosin for analysis.</p><p><b>RESULTS</b>Among the various dosage formulations of agkistrodon, high-dose powder, which was equivalent to an amount of 6 g/day in adults, showed better effects on the inhibition of joint swelling and reduction of arthritis index score. The relatively low levels of serum IL-1 and anti-type II collagen IgG antibodies, as well as the X-ray radiography and pathology results, further proved the superiority of the high-dose powder over the other formulations. The effect of decoction on inhibiting joint swelling was inversely proportional to the dosage. Other effects, such as reduction of arthritis index score and the levels of serum IL-1 and anti-type II collagen IgG antibodies, were directly proportional to the dosage. While the use of large dose agkistrodon wine led to negative effects.</p><p><b>CONCLUSION</b>These data highlight the potential function of high-dose agkistrodon powder, which was equivalent to an amount of 6 g/day in adults. The powder can quickly relieve the symptoms of rheumatoid arthritis and prevent aggravation of disease, especially during the early period.</p>
