RESUMO
Objective To investigate the expression of miRNA (miR-21) in mucosa-associated lymphoid tissue(MALT) lymphomas and its relationship with the effects in CHOP regimen. Methods Lymph gland tissues and preoperative peripheral blood of 52 patients pathologically diagnosed with MALT lymphoma in Department of Hematology of Affiliated Hospital of Hebei University of Engineering from January 2015 to December 2017 were collected; meanwhile, 10 tissues from patients with lymphadenitis and 20 peripheral serum from healthy examination patients were also collected. Quantitative real-time polymerase chain reaction (qPCR) was used to compare the lymph gland tissues in MALT lymphoma patients and lymphadenitis patients, and the expression of miR-21 in peripheral serum of MALT lymphoma and healthy people. The selected 20 cases of MALT lymphoma were given CHOP regimen treatment for 6 cycles, and then the efficiency and inefficiency were compared; at the same time, the expression of miR-21 in peripheral serum of the patients in the effective group was detected. Results The relative expression of miR-21 of lymph node tissues in lymphadenitis patients and MALT lymphoma patients was 1.03±0.12 and 4.53±0.73 respectively, and the relative expression of miR-21 in preoperative peripheral serum of healthy people and MALT lymphoma patients was 0.83±0.04 and 3 . 87 ± 0 . 21 respectively , and the differences were statistically significant (P ＝ 0.047, P ＝ 0.044). After 6 cycles of CHOP regimen, the total effect rate of MALT lymphoma was 70 % (14/20), and the relative expression of miR-21 in preoperative and postoperative peripheral serum for the patients who obtained the effective results after CHOP regimen was 3.95 ±0.08 and 1.62 ±0.41, and the differences were statistically significant (P＝ 0.035). Conclusions The expression of miR-21 has a certain correlation with the occurrence and development of MALT lymphoma. Furthermore, the serum miR-21 expression may be related to the effect of CHOP regimen chemotherapy in MALT lymphoma.
RESUMO
Objective@#To investigate the effect of thalidomide on the expressions of Th17 cells, interleukin 17 (IL-17), macrophage inflammatory protein 3α (MIP3α) in peripheral blood of patients with diffuse large B-cell (DLBCL) and 3-year survival rate.@*Methods@#Sixty patients with DLBCL from January 2009 to January 2013 in the Affiliated Hospital of Hebei University of Engineering were enrolled. According to envelope method, the patients were randomly divided into the combined group (n = 30, thalidomide combined with CHOP regimen) and chemotherapy group (n = 30, CHOP regimen alone). Clinical adverse reactions, efficacy, the expressions of Th17 cells, IL-17, MIP3α in peripheral blood before and after treatment, and 3-year survival rate between two groups were compared.@*Results@#The total effective rate and 3-year survival rate were 73.3% (22/30) vs. 46.7% (14/30), 87.4% vs. 40.7% respectively in the combined group and the chemotherapy group (both P < 0.05). The levels of Th17 cells percentage and the expression level of IL-17 before and after treatment in combined group were (0.52±0.14)% vs. (1.61±0.53)%, (5.61±0.75) pg/ml vs. (8.87±1.84) pg/ml, and the difference was statistically significant (both P < 0.05). However, the expression levels of Th17 cells and IL-17 before and after treatment in the chemotherapy group were (0.75±0.05)% vs. (0.74±0.07)%, (5.69±0.29) pg/ml vs. (5.26±0.24) pg/ml, and there was no statistical difference (both P > 0.05). The levels of IL-17 and MIP3α mRNA in peripheral serum before and after treatment in the combined group were 8.51±0.23 vs.13.96±0.89, 27.4±1.5 vs. 83.0±8.5 (both P < 0.05). While in the treatment group before and after treatment the above mentioned were 8.85±0.32 vs. 9.45±0.55, 23.7±1.8 vs. 38.7±5.5, and the difference was no statistically significant (both P > 0.05). There was no statistical difference in the adverse reactions between the combined group and the chemotherapy group (P > 0.05).@*Conclusion@#Thalidomide may prolong survival time of DLBCL patients by intervening Th17 cells and associated cytokines.

RESUMO
Background:1 α,25-dihydroxyvitamin D3 [1,25 (OH) 2 D3],the active form of vitamin D,is reported in some studies having antifibrotic potential in liver fibrosis,however,its mechanism is not fully clarified.MicroRNAs (miRNAs) have recently been shown could regulate the proliferation and activation of hepatic stellate cells (HSCs),and are involved in the promotion or inhibition of liver fibrosis.Aims:To explore whether the inhibiting effect of 1,25 (OH) 2 D3 on activation of HSCs is by regulating miRNAs expression.Methods:Literature review and qPCR method were used to screen out the differentially expressed miRNAs between transforming growth factor-β1 (TGF-β1)-stimulated (activated) HSCs and the inactivated HSCs.Then the HSCs were co-cultured with TGF-β1 and the mimic of differentially expressed miRNA,the negative control mimic,1,25(OH)2D3 and DMSO,respectively,and the cell viability and apoptosis were determined by CCK-8 assay and flow cytometry.Results:Expression of miR-146a was down-regulated in activated HSCs (P ＜ 0.05).Compared with HSCs in DMSO group,the expression of miR-146a was significantly up-regulated in HSCs treated with 1,25 (OH) 2 D3;meanwhile,the cell viability was decreased and the apoptosis was increased (P all ＜ 0.05).In HSCs transfected with miR-146a mimic,the expression of miR-146a was up-regulated,the cell viability was decreased,and the apoptosis was increased similarly with HSCs in 1,25 (OH)2D3 group (P all ＜ 0.05).Conclusions:Regulation of miR-146a expression might be one of the important mechanisms of 1,25 (OH) 2 D3 in inhibiting TGF-β1-stimulated HSC activation and inducing apoptosis in HSCs.

RESUMO
Objective: To study the effects of Rhizoma Polygoni Cuspidati on expression of transforming growth factor beta 1(TGF-?1) in rats with pulmonary fibrosis induced by bleomycin.Method: 120 male SD rats were randomly divided into five groups: the control group(n=30),the bleomycin(BLM) model group(n=30),the Rhizoma Polygoni Cuspidati prophylactic group(n=30),the 7 th day treatment group(n=20) and the 28 th day treatment group(n=10).The rat models of pulmonary fibrosis were established by intratracheal injection of bleomycin, while the control group was given with normal saline instead.The Rhizoma Polygoni Cuspidati prophylactic group received intragastric administration with 4ml?kg-1?d-1 Rhizoma Polygoni Cuspidati 2 days before setting up models.The 7 th day treatment group and the 28 th day treatment group received the treatment on the seventh day and the twenty-eighth days after establishing models respectively.The other two groups received saline instead.On the 3rd,7th,14th,28th,42th and 56th day after instillation of bleomycin,lung samples were obtained and the content of hydroxyproline in lung tissue homogenate was detected to judge the degree of fibrosis and the therapeutic efficacy.At the same time the express of TGF-?1mRNA and TGF-?1 protein was examined by RT-PCR and immunohistochemical method.Results: Compared with the model group,the content of hydroxyproline in the Rhizoma Polygoni Cuspidati prophylactic group and the 7th day treatment group decreased significantly(P
