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.

Objective: To evaluate the current cancer burden and the dominant risk factors of cancer in Eastern Asia, and to provide the preventive strategies for cancer control. Methods: The measures such as incidence, mortality and prevalence of cancer were selected to examine the cancer burden by using global cancer databases and the data of cancer incidence in the five continents, and the future preventive strategies were developed on the basis of the results. Results: The new cancer cases, cancer deaths and the cases living with cancer in Eastern Asia were more than 2.8 million, 2 million and 4.9 million per year, respectively. The five most-frequently-diagnosed cancers were gastric cancer (18.7%), lung cancer (16.9%), liver cancer (14.2%), esophageal cancer (9.4%) and colon/rectal cancer (9.1%), accounting for 68% of the total new cancer cases per year. We predicted that the numbers of the new cancer cases and the cancer deaths in Eastern Asia by the year 2050 were estimated to be 6 million and 4.5 million, respectively. Conclusion: Cancer is a current serious public health problem in Eastern Asia, and will be a continuosly substantial problem in the future. The guidelines of cancer control should be focused on the preventive strategies in Eastei Asia.

Objective To summarize and analyze the failure reason of internal fixation operation in peritrochanteric fractures and propose appropriate prevention measures.Methods The clinical data of 229 patients with peritrochanteric fractures were retrospectively analyzed,the failure reason of internal fixation was analyzed by the univariate and multivariate Logistic regression analysis.Results The univariate analysis showed that the patients' age,gender composition,types of internal fixation had no significantly correlated with the failure of internal fixation (P ＞ 0.05) ; the Garden reset index,bone quality,fracture type and load time had significantly correlated with the failure of internal fixation (P ＜ 0.05).The multivariate Logistic analysis showed that load time was the independent risk factors for fixation failure (OR =13.515).Conclusion The weight-bearing time points should be selected according to the bone quality,fracture type,and degree of intraoperative reset,thereby reducing the risk of surgery failure.

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.

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.

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.
