Objective To investigate the possible role of mycobacterial infection in the pathogenesis of sarcoidosis.Methods DNA fragments of mycobacterial16S rRNA gene and the complex-specific insertion sequence IS6110of M.tuberculosis were detected by polymerase chain reaction(PCR)in formalin-fixed,paraffin-embeded skin biopsy specimens from12patients with sarcoidosis.Results Mycobacterial common sequence16S rRNA gene was found in6patients,among which5were further confirmed as M.tuberculosis,the other one was atypical mycobacteria.The IS6110DNA fragment amplified by PCR was confirmed by DNA sequencing.Conclusion The above findings suggest an aetiological role of mycobacterial infection,especially M.tuberculosis,in some patients with sarcoidosis.

ObjectiveTo investigate the effect of down-regulating epidermal growth factor receptor (EGFR) expression on Bleomycin induced pulmonary fibrosis in mice.MethodsForty 4 ～6 week aged C57BL/c male mice were randomly divided into control,bleomycin,bleomycin plus EGFR RNAi groups and RNAi negative control group.Bleomycin group were treated with bleomycin (3 mg/kg) by endotracheal injection on day 0,control group were treated with PBS.And bleomycin plus EGFR RNAi group were received EGRF siRNA plus bleomycin intratracheal administration.RNAi negative control group received negative EGRF siRNA plus bleomycin intratracheal administration.Mice were sacrificed 10 days after the treatments.Hydroxyproline (HYP) assay was performed in the lung tissue.The lung tissue slides were examined pathologically with H.E.staining,and EGFR mRNA expression was detected by reverse transcriptasepolymerase chain reaction (RT-PCR) technique.Western blot were performed to identify the protein level.of total EGFR and phosphorylated EGFR.ResultsHistological examination of lung specimens demonstrated that EGFR siRNA administration lessened lung fibrosis induced by bleomycin and significantly reduced HYP content (543.00±25.89 vs 900.73±31.77,P＜0.01).EGFR mRNA (0.31±0.05 vs 0.75±0.08,P ＜0.01) and protein expression(1.53±0.47 vs 2.56±0.37,P ＜0.01) in EGFR siRNA-treated mice was significantly decreased.The expression of phosphorylation of EGFR protein (1.78±0.35 vs 2.84±0.51,P ＜0.01) and EGFR protein in RNAi group was less than in bleomycin group.Conclusions EGFR RNAi reduced the BLM-induced lung fibrosis by inhabiting EGFR activation.

Gastric cancer stem cells are defined as a subset of gastric cancer cells that possess stem cell properties,including self-renewal and multiplex differentiation potential,and have crucial roles in tumor initiation,progression,invasion,metastasis and recurrence.Epithelial-mesenchymal transition (EMT) can facilitate the invasion and metastasis of cancer cells to distant tissues,and confer the metastatic cancer cells some abilities of stem cells.Several transcription factors of EMT,signaling pathways and microRNAs (miRNAs) are involved in the process of regulating gastric cancer stem cells.

Objective To study the effect of transmembrane tumor necrosis factor-alpha (TM-TNF-αt) on human cervical carcinoma HeLa cells,and explore the correlations with silencer of death domain (SODD).Methods The expression of proliferating cell nuclear antigen (PCNA) was detected by immunocytochemistry.The expression of SODD in human cervical carcinoma HeLa cells undisposed and after disposed with TM-TNF-α was detected by reverse transcription-polymerase chain reaction,and the influence of TM-TNF-α on human cervical carcinoma HeLa cells was analyzed.Results The positive rate of PCNA in undisposed human cervical carcinoma HeLa cells was 80.3％ (155/193),in human cervical carcinoma HeLa cells disposed with TM-TNF-α was 46.7％ (85/182),there was statistical difference (P ＜ 0.05).The cycle index of polymerase chain reaction in human cervical carcinoma HeLa cells was 28 times,the amplification product was disposed by 2％ agarose gel electrophoresis,the gray scale disposed by TM-TNF-α and undisposed human cervical carcinoma HeLa cells were 1.377 ± 0.170 and 0.815 ± 0.040,there was statistical difference (P ＜ 0.05).Conclusion TM-TNF-α has obvious cytotoxic effect on human cervical carcinoma HeLa cells in vitro which may due to its up-regulating the expression of SODD.

Chemotherapy with or without molecule-targeting agents is the primary choice for patients with unresectable metastatic coloreetal cancer. New treatment strategies like intermittent therapy and maintenance therapy may not inferior to treatment until progression or unacceptable toxicity in maintaining the benefit for patients who responded or had stable disease after the first-line therapy,and also can reduce the drug related side effeets and improve the quality of life.
