Purpose To investigate the clinicopathologic changes of the lung epithelial tumor with epithelioid granuloma. Methods E-leven cases of lung malignant tumor with epithelial epithelioid granuloma reaction were studied according to the histological changes of lung epithelial tumor, immunophenotype, acid-fast staining, and tuberculosis PCR test results combined with follow-up data. Results The mean age was 62. 3 years, and male to female ratio was 10∶ 1. The main clinical manifestations displayed a cough, chest pain, fever and hemoptysis or bloody sputum. Nine cases were malignant tumors, tuberculosis or inflammatory lesions was 1 case each in pre-vious surgery. The tumor with epithelioid granuloma formation of the 11 cases displayed in the same site ( mixed) . The histopathologic changes of the lesions showed a epithelioid or typical tuberculous granulomas formation, including 4 cases of adenocarcinoma, 5 cases of squamous cell carcinoma and 2 cases of neuroendocrine tumors. The acid-fast bacilli staining was positive in 3 cases;6 cases were positive for PCR detection of mycobacterium tuberculosis. 5 patients died within 2 years due to various causes. Conclusions The lung epithelial tumors with epithelioid granuloma is more commonly found in the middle-aged, The signs and symptoms of the patients are similar to primary epithelial malignant tumors of the lung . The biological behavior was progressive with poor prognosis. The diagnosis of the lesions depends on pathological examination. It is very important to pay more attention to the pathological examination, especially in lung puncture samples, and the differential diagnosis for a definate diagnosis and treatment.

Objective To investigate the effect of human lung cancer-associated fibroblasts (CAF) on the radiosensitivity of lung cancer cells when CAF is placed in direct contact co-culture with lung cancer cells.Methods Human lung CAF was obtained from fresh human lung adenocarcinoma tissue specimens by primary culture and subculture and was then identified by immunofluorescence staining.The CAF was placed in direct contact co-culture with lung cancer A549 and H1299 cells,and the effects of CAF on the radiosensitivity of A549 and H1299 cells were evaluated by colony-forming assay.Results The human lung CAF obtained by adherent culture could stably grow and proliferate,and it had specific expression of α-smooth muscle actin,vimentin,and fibroblast activation protein,but without expression of cytokeratin-18.The plating efficiency (PE,％) of A549 cells at 0 Gy irradiation was (20.0 ± 3.9) ％ when cultured alone versus (32.3 ± 5.5) ％ when co-cultured with CAF (t =3.16,P ＜ 0.05),and the PE of H1299 cells at 0 Gy irradiation was (20.6 ± 3.1) ％ when cultured alone versus (35.2 ± 2.3) ％ when co-cultured with CAF (t =6.55,P ＜0.05).The cell survival rate at 2 Gy irradiation (SF2) of A549 cells was 0.727 ±0.061 when cultured alone versus 0.782 ± 0.089 when co-cultured with CAF (t =0.88,P ＞ 0.05),and the SF2 of H1299 cells was 0.692 ±0.065 when cultured alone versus 0.782 ± 0.037 when co-cultured with CAF (t =2.08,P ＞0.05).The protection enhancement ratios of human lung CAF for A549 cells and H1299 cells were 1.29 and 1.25,respectively.Conclusions Human lung CAF reduces the radiosensitivity of lung cancer cells when placed in direct contact co-culture with them,and the radioprotective effect may be attributed to CAF promoting the proliferation of lung cancer cells.

Staphylococcus was highly sensitive to nitrofurantoin ,rifampicin ,piperacillin/tazobactam ,linezolid ,teicoplanin and vancomycin ,but their resistance rate to ampicillin/sulbactam ,oxacillin ,penicillin and clarithromycin was high .The resistance rate of E .faecium to the majority of antimicrobial agents was obviously higher than that of E .faecalis ,excluding imipenem ,chloramphenicol and tetracy-cline .Vancomycin and linezolid still remain the strongest antibacterial activity to Enterococcus .Conclusion The distribution and drug resistance of pathogenic bacteria in Chongqing present regional particularity ,and antibiotic resistance is severe .It is significant to strengthen the epidemiology study of pathogenic bacteria and to develop policies to intervene in the use of antimicrobial agents .

Objective To evaluate the relationship between intestinal metaplasia (IM) and helicobacter pylori infection in elderly patients with chronic gastritis. Methods The patients over 60 years old and diagnosed as chronic gastritis by endoscopy from January 2008 to December 2009 were divided into two groups by pathological appearance. One group was chronic gastritis with IM (IM group), the other was chronic gastritis without IM (NIM group). The infection of helicobacter pylori, activity of inflammation, atrophy of gland, and folliculus lymphaticus in gastric mucosa were observed. Results The infection of helicobacter pylori, infiltration of neutrophil and atrophy ratio of gland were significantly higher in IM group than in NIM group (52.7% vs. 37.3%, 35.5% vs.24.0 %, 36.6 % vs. 3.5%, x2 = 10. 677, 7.641, 95. 606; P = 0. 001, 0. 006, 0. 000, respectively).There was no statistical difference in presentation of folliculus lymphaticus between IM group and NIM group (x2 = 0.003, P=0. 957). The infiltration of neutrophil and presentation of folliculus lymphaticus were significantly higher in helicobacter pylori positive patients than in helicobacter pylori negative patients (45.8% vs. 14.8%, 42.6% vs. 4.2%, both P=0.000). Conclusions The appearance of IM seems to be related with helicobacter pylori infection, activity inflammation and atrophy of gland. The presentation of folliculus lymphaticus seems to be closely related with helicobacter pylori infection. The eradication treatment of helicobacter pylori infection in the elderly chronic gastritis patients should be strengthened.
