RESUMEN
Objective To explore the monitoring analysis of pulmonary tuberculosis related antibodies and conduct and risk assessment of tubercuosis. Methods A total of 39 605 patients who were treated in Baotou tuberculosis prevention and treatment center from January 2012 to December 2016 were enrolled for epidemiological investigation. Smear, imaging, tuberculin test, clinical signs and anti-TBGL and anti-LAM antibody tests were used to diagnose the effective serum samples, and drug sensitivity tests were conducted to record the positive rate and drug resistance of the patients. Univariate and multivariate analyses were performed on all the factors influencing the recurrence of the patients including the gender, age, marriage, nutritional status, initial lesion range, regular treatment, drug withdrawal residual cavity, drug resistance, treatment style, course of treatment, and comorbidities. Results There were significant differences in epidemiological survey results in age, occupation and detection methods (P<0.05). A total of 22 703 strains were obtained in the drug sensitivity test, 19.99% of which were isoniazid resistance, 15.54% were streptomycin resistance, and 15.19% were multi-drug resistance.. In the process of antibody diagnosis, the positive rate of the parallel test was significantly higher than that of the single test and the series test, with a statistically significant difference (P<0.05). The results of risk factor analysis showed that age, drug withdrawal residual cavity, and drug resistance were important risk factors influencing the recurrence of the patients (P<0.05). Conclusion The incidence rate of tuberculosis in Baotou from 2012 to 2016 was affected by age, occupation and other factors. It is of great significance to develop diagnostic methods with higher sensitivity. The parallel detection of anti-TBGL and anti-LAM antibodies had high sensitivity and specificity, which is an important diagnostic method for tuberculosis with high application value. At the same time, the recurrence of tuberculosis is affected by many factors, which requires patients to be cooperative with treatment in order to improve the cure rate

@#ObjectiveTo analyze the clinical value of anti-myelin basic protein (MBP) antibody in multiple sclerosis (MS).MethodsDetect the anti-MBP antibody in serum of 56 patients with MS, 30 patients with other neurological diseases (OND)and 36 normal control(NC).ResultsThe positive rate were 78.6% of MS, 50% of OND. There was significant difference amonge MS, OND and NC.ConclusionAnti-MBP antibody detection maybe provided evidence for the diagnosis and therapy of MS.
RESUMEN
A new group of gastric cancer associated antigens in sera of patients with rectal cancer, benign diseases and normal human were detected by MG series monoclonal antibodies against gastric cancer. The average values of normal persons plus 3 standard deviations was set as the highest limit of normal value. The positive rate were 69.7% (23/33) in sera of patients with rectal cancer, and 4%(1/25) in sera of patients with benign diseases. The values of MG-Ags were decreased to normal level 8-10 days after surgical removal in 5 patients of rectal cancer. The results of test suggest that determination of MG-Ags in serum of patients might be helpful in the diagnosis of rectal carcinoma.
