Although the association of tuberculosis (TB) and the development of lung carcinoma (LC) has been acknowledged, the underlying mechanism remains not clarified. Since sustained and repeated local inflammation and tissue remodeling have been suggested to be responsible for the high incidence of developing CL from TB, we hypothesize that macrophages may play a critical role in the process. To prove it, we induced TB in mice by injection of virulent Mycobacterium tuberculosis (MTB). Then the mice were allotted into two groups. One group received weekly tail vein injection of 20 μg saporin-conjugated antibody against the pan-macrophage surface marker CD11b to eliminate macrophages, while the other group received injection of control IgG in the same frequency. Six months later, the development of LC was determined by histology. We found that the occurrence of LC in TB mice that received macrophage depletion was significantly lower than those in control TB mice without macrophage intervention. These data suggest that macrophages may promote the progression of TB into LC.
Objective To detect antigen-specific INF-γsecreting cells in CSF by ELISPOT assay to deter-mine its clinical value for TBMdiagnosis.Methods The study selected 1 04 patients with tuberculous meningitis and 40 people without tuberculous meningitis to detect their INF-γsecreting cells in CSF and blood by ELISPOT assay. Then the results were compared with AFB staining,Mtb culture,quantitative PCR,and Mtb antibodies.Results The sensitivity of CSF-ELISPOT assay was 92.3%,the specificity was 94.1%,which were higher than other assays (P<0.05).The CSF-ELISPOT assay was better than other assay in the diagnosis of TBM (Kappa=0.856,P<0.001 ).Conclusion The CSF-ELISPOT assay,with high sensitivity and specificity,will be a rapid diagnostic method for TBM.
ObjectiveTo investigate the mycobacterium tuberculosis bacterium distribution of drug-resistant tuberculosis patients, and analyze its drug resistance feature.Method568 cases of pulmonary tuberculosis patients’ lesion specimen were collected from June 2012 to June 2014, and used bacterial culture, identiifcation and drug sensitization experiments, the distribution of mycobacterium tuberculosis bacteria and drug resistance were analyzed.ResultThere were 198 cases of human type mycobacterium tuberculosis, 4 cases of mycobacterium bovis, 12 cases of NTM in 214 cases of culture-positive pulmonary tuberculosis. The difference of percentage among three types of mycobacterium tuberculosis was signiifcantly (P<0.05). There were 58 cases of drug-resistant strains of mycobacterium tuberculosis, 1 case of drug resistance of cattle mycobacterium tuberculosis, 1 case of drug resistance NTM, the difference was signiifcant (P<0.05); 12 cases of multi drug resistance in human mycobacterium tuberculosis, and there were no multi drug resistance in mycobacterium bovis and NTM, the difference was signiifcant (P<0.05); drug sensitization experiments showed that the highest rates of drug resistance was SM, the lowest was PAS, the difference was signiifcantly (P<0.05); Logistic regression analysis showed that there was significant association between treatment duration and resistance rates (P<0.05).ConclusionTB drug resistance is more serious and should strengthen monitoring of drug resistance, and based on susceptibility testing to select reasonable and effective chemotherapy.
Objective To evaluate the diagnostic value of IGRA in patients with tuberculous pleural. Meth-ods 116 patients with suspected tuberculosis pleurisy were selected in this study, and their whole blood and pleural effusion were given T-SPOT. TB detection. PBMCs isolated from whole blood and pleural effusion were co-cultured with mycobacterium tuberculosis-specific antigens ESAT-6 and CFP-10, then the spots were counted which formed by specific T cells. Results 91 patients were diagnosed with active TB infection, and the other 25 patients were diag-nosed with non-TB infection. For diagnosing TBP, the sensitivity and specificity of PBMCs from whole blood were 79. 1% and 64. 0% respectively. The relative proportions with cells from pleural effusion were 90. 1% and 88. 0% re-spectively. The positive rate of T-SPOT. TB was significantly higher in the ATB group than in the non-TB group ( P<0. 001). The results of T-SPOT. TB combined whole blood PBMCs with pleural effusion cells had a positive predictive value of 100% (72/72) and a negative predictive value of 94. 1% (16/17). Conclusion T-SPOT. TB assay with pleural effusion cells can be used in the diagnosis of TBP, and the diagnostic value will be even greater while combi-ning with the IGRA results from whole blood and pleural fluid cells.

OBJECTIVE To observe the relationship between the genetic polymorphism of P450-2E1 and the risk for antituberculosis drug-induced hepatotoxicity in a Chinese population. METHODS Blood samples and clinical data were collected from 85 patients with antituberculosis drug-induced hepatotoxicity and 100 tuberculosis patients without hepatotoxicity as the control. DNA was extracted from the blood samples, and the frequencies of P450-2E1 RsaI genotypes were analyzed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The relationship between the polymorphisms of P450-2E1 RsaI and the antituberculosis drug-induced hepatotoxicity was analyzed. Predisposing factors for antituberculosis drug-induced hepatitis, such as gender, age, and polymorphism of P450-2E1 RsaI were evaluated by using logistic regression analysis. RESULTS The frequencies of the 3 gene types P450-2E1 RsaI c1/c1, c1/c2, and c2/c2 were 75% (64/85), 20% (17/85) and 5% (4/85) respectively in patients with antituberculosis drug-induced hepatotoxicity, and 61% (61/100), 30% (30/100), and 9% (9/100) respectively in the controls. A statistical difference was found between the cases and the controls (chi(2) = 4.284, P < 0.05, OR = 2.016, 95%CI = 1.058 - 3.842). Logistic regression analysis showed that the polymorphism of P450-2E1 RsaI remained a significant independent risk factor for antituberculosis drug-induced hepatotoxicity after adjustment for age, gender and body mass index. CONCLUSION Polymorphisms of P450-2E1 were found to be significantly associated with the risk of antituberculosis drug-induced hepatotoxicity, and the c1/c1 genotype was one of the risk factors.
Objective: To investigate and analyze the clinical effect of diabetes combined with pulmonary tuberculosis with continuous sub- cutaneous insulin infusion (CSII). Methods: 51 cases of diabetes combined with pulmonary tuberculosis were randomly divided CSII group and the MSII group,CSII group was treated with CSII,MSII group was treated with subcutaneous injection therapy treatment. at the same time,two groups were given anti-TB treatment. Observation of sputum conversion and absorption of lesions,blood glucose in patients with standard time,the amount of insulin, the incidence of low blood sugar,insulin suspended after blood sugar control to maintain a good time. Results: At the 1-month and 3 months after,the sputum conversion rate and absorption of lesions significantly increased in the CSII group,and compared with the MSII group the difference was significant ( P < 0. 05 ). CSII group and MSII group compared to standard blood sugar a short time, use less insulin,in- sulin-out after a good blood sugar control to maintain the long hours,low incidence of hypoglycemia ( P < 0. 05 ). Conclusion: CSII treatment of diabetes combined with pulmonary tuberculosis can better control the disease and promote negative sputum.
