Effect of schisandrin B on lung mRNA expression of transforming growth factor-β1 signal transduction molecule in rat lungs exposed to silica

Objective To investigate the effects of schisandrin B (Sch-B) on expression of transforming growth factor-β1 (TGF-β1) and signal transduction molecule mRNA in rat lungs exposed to SiO2,and explore the intervention mechanism of Sch-B on pulmonary fibrosis induced by SiO2. Methods Ninety six Wistar rats were randomly divided into control (normal saline) group, SiO2 group and SiO2 plus Sch-B group.The rats were exposed to SiO2 by direct tracheal instillation to establish the silicotic animal models. SiO2 group and SiO2 plus Sch-B group were treated with 1ml SiO2 (50 mg/ml) for each rat From the first day after model establishment, SiO2 plus Sch-B group were orally given Sch-B (80 mg/kg) a day, control group and silica group were orally given olive oil. On the 3rd, 7th,14th and 28th days after treatment, 8 rats in each group were sacrificed and samples were collected. The histo-pathological examination of lung was performed by HE staining. The expression levels of TGF-β1 、TGFβR Ⅱ and Smad4 mRNA in the lung tissues were detected by RT-PCR. Results The results of histo-pathological examination showed that in SiO2 group, lung tissues were injured obviously; the alveolar inflammation with alveolus interval edema and inflammation cell infiltration appeared on the 3rd and 7th days; the alveolus interval became thicker, became thicker, fibroblast and collagen matiix increased markedly on 14th day; the alveolar structure was damaged, alveolar wall thickened obviously,collagen aggradation and pulmonary fibrosis displayed on 28th day. The alveolar inflammation and pulmonary fibrosis in SiO2 plus Sch-B group were significantly less than those in SiO2 group. The expressions levels of TGF-β1、TGFβR Ⅱ and Smad4 mRNA (TGF-β1: 1.03±0.31 、1.33±0.39、1.08±0.26、0.82±0.16,TGF-βR Ⅱ:0.65 ±0.11、0.80 ±0.16、0.83 ±0.24、0.62 ±0.15, Smad4: 0.87 ±0. 15、0.68 ±0.11、0.78 ±0.19、0.30 ±0.08) in SiO2group were significantly higher than those in the control group (TGF-β1:0.59±0.22、0.55 ±0.25、0.56±0.20、0.55 ±0.12,TGR-βR Ⅱ:0.28 ±0.13、0.31 ±0. 15、0.34 ±0.15、0.27 ±0.09,Smad4:0.23 ±0.11、0.40 ±0. 12、0.39 ±0.12、0.18±0.06)(P＜0.01 or P＜0.05), but the expression level of TGF-β1 mRNA was the highest on the 7th day. The expression levels of TGF-β1 and Smad4 mRNA (TGF-β1: 0.68 ±0.28、0.88 ±0.25、0.75 ±0.11、0.61 ±0. 14,Smad4:0.25 ±0.12、0.45 ±0.09、0.44 ±0.07、0.21 ±0.04) in SiO2 plus Sch-B group were significantly lower than those in SiO2 group (P＜0.01 or P＜0.05),but there were no significant differences of the TGFβR Ⅱ mRNA expression levels between SiO2 group and SiO2 plus Sch-B group. Conclusion Sch-B can reduce the pulmonary fibrosis induced by SiO2 through inhibition of the mRNA express of TGF-β1 and Smad4 in the lung tissue, modulating the TGF-β1/Smad4 signal transduction pathway and inhibiting the target gene activation.     

中药红昇丁治疗口腔脓性骨髓炎

自从外科金伯恭先生介紹使用紅昇条及紅昇丁治疗骨結核有疗效显著后,我科(口腔科)曾使用于口腔下頜骨髓炎,亦得良好效果.过去遇到这类疾病一貫采用开刀,刮除病灶及死骨。如手术不彻底,术后往往有化脓成瘘的麻煩。今用中医的办法,既縮短疗程,又減少病人痛苦。茲將兩例典型例子向同道介紹。一、药的来源 紅昇丁及紅昇条均为中医外科成药,患部二寸以內的插丁,二寸以外的插条。二、治疗方法 1.上药前先以探針探明瘻管的長短方向,如管深而頑固的,須先以槽针翻入少許紅昇丹到瘡口底部。以加强药力。 2.换药前先用百分之三双氧水二十西西注入注射器,再套一尼龙管塞入創口,二十西西分四次冲洗,每洗一次,停兩三分鐘再洗,使管內死骨或腐性分泌

丝裂霉素或顺铂对离体淋巴因子激活的杀伤细胞增殖和抗膀胱癌细 …

AIM: To study the effect of mitomycin (Mit) or cisplatin (Cis) on the proliferation of lymphokine-activated killer (LAK) cells in patients with transitional cell cancer of bladder and their cytolysis to bladder tumor cells. METHODS: LAK cell proliferation was assayed in the presence of Mit or Cis by cell counting. Bladder cancer cell lines BIU-87 and EJ were cultured as target cells and cytotoxicity of LAK cells was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. RESULTS: The proliferation of LAK cells induced by recombinant interleukin-2 (IL-2) was inhibited by Cis in a concentration-dependent manner and was decreased to 55.3% at 100 mg.L-1 compared with control at 96 h. The enhanced growth of the LAK cells was observed with Mit 5-10 mg.L-1 from 48 to 96 h. Cis 10 mg.L-1 increased the cytotoxicity against BIU-87 and EJ cells. CONCLUSION: Immunomodulatory effect of chemotherapeutic agents on LAK cell proliferation induced by IL-2 in patients with bladder cancer mainly depends on the drug itself.
