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.

Objective To investigate the change of serum resistin levels in patients with obstructive sleep apnea hypopnea syndrome(OSAHS).MethodsPolysomnography(PSG)was performed in 58 patients with OSAHS and in 26 controls without differences in age and BMI.Serum resistin levels were measured by ELISA.Results(1)Serum resistin levels were significantly higher in patients with OSAHS than those in control group.(2)FPG levels were significantly higher in patients with OSAHS than those in control group.(3)TG levels were significantly higher in patients with OSAHS than those in control group.(4)Serum resistin levels were correlated positively with FPG in obesity patients with OSAHS、nonobesity patients with OSAHS and nonbesity controls group.(5)Serum resistin levels were correlated positively with TG in obesity patients with OSAHS、nonobesity patients with OSAHS and nonbesity controls group.(6)Serum resistin levels were correlated positively with BMI in OSAHS.(7)Serum resistin levels were correlated negatively with LSaO2 in OSAHS.(8)Serum resistin levels were correlated positively with AHI in OSAHS.ConclusionDetermination of serum resistin levels may be the predictors of the severity of OSAHS and it also contributes a lot taking measures to prevent and control the OSAHS complication occurrence and reduce the mortality.

Objective: To establish a rapid approach to the detection and identification of Mycobacteria from lesions of patients with suspected Mycobacterial infections. Methods: Specimens were obtained from five patients suspected to have Mycobacterial infections. DNA extracted from clinical samples was amplified by nested PCR. The PCR products were digested with Hha Ⅰ, MboⅠ, and BstUⅠ restriction enzymes and applied to PAGE. The species of Mycobacteria were determined by restriction fragment length polymorphism (RFLP) analysis. Identification of Mycobacteria culture was also performed in 3 patients. Results: M. marinum was found in two patients diagnosed as swimming pool granuloma. M. tuberculosis was found in one patient diagnosed as infectious skin granuloma. All these 3 Mycobacteria were confirmed by Mycobacteria culture. A strain of M. tuberculosis and a strain of M. fortuitum were detected in remain two patients. Conclusion: The results above indicate that PCR-RFLP analysis is rapid and reliable in detection and identification of different Mycobacteria species from skin tissues. Application of this method will be helpful for early diagnosis and treatment of Mycobacteria skin infections.
