ABSTRACT
Objective To statistically summarize the adverse reactions of anti-TB drugs treatment,to analyze the influencing factors of leucopenia and to compare the effect of Qijiao Shengbai Capsule and Leucogen Tablet in the treatment of leucopenia.Methods The adverse reactions in 840 TB patients diagnosed from September 2014 to November 2015 were statistically analyzed.The influencing factors of leucopenia were analyzed.Finally,the effect of Qijiao Shengbai Capsule(n=480) and Leucogen Tablets (n=360) for treating leucopenia.Results Clinicians paid less attention to routine blood monitoring (39.4 ％).Among adverse reactions,the damage of liver function had the highest incidence rate(abnormal liver enzymes 27.0％,increased bile acid 8.2％),followed by leukopenia [25.4％,mainly degree Ⅰ (16.9％)];female patients(P=0.000) and complicating liver damage(P=0.010) might be the risk factors of leukopenia.After treatment by two kinds of drug,white blood cells count was increased,the difference was statistically significant(P=0.000).Conclusion The occurrence rate of leucopenia is higher,females and liver function damage are easier to appear,so more attention should be paid to monitoring the blood routine in return visit.The two kinds of drug for treating leucopenia induced by anti-TB drugs have definite effect and could be used in clinic.
ABSTRACT
Objective To preliminarily explore the application of terahertz spectroscopy in the early detection of lung cancer by comparing the differences among lung cancer tissues,paracancerous tissues,and normal lung tissues with terahertz spectroscopy and screen the suitable terahertz frequency for specific diagnosis of lung cancer.Methods Thirty groups of lung tissue samples from non-small cell lung cancer patients at stage of Ⅰ to Ⅲ A were collected,and each group contained lung cancer tissue,paracancerous tissues,and normal lung tissue from the same patient.These lung cancer specimens included 17 cases of adenocarcinoma,10 cases of squamous cell carcinoma,2 cases of large cell lung cancer,and 1 case of sarcomatoid carcinoma.Terahertz spectroscopy from 0.2 THz to 2.0 THz was used to detect these tissue samples,and the absorption coefficient was compared.Results ① The absorption coefficient was significantly higher in the lung cancer tissues than the normal lung tissues.② Terahertz spectroscopy at a frequency of 0.8 to 1.4 THz may have the specific diagnostic value of lung cancer.Conclusion Since the absorption rate is higher in the lung cancer than the normal lung tissue,which is suggested that terahertz spectroscopy may be regarded as a novel non-invasive diagnostic approach for lung cancer.The specific diagnostic value of the terahertz frequency may be 1.4-2.0 THz for lung cancer.
ABSTRACT
Objective To investigate the distribution status of Pseudomonas aeruginosa (PA) in children in Suining area and the changes of drug-resistance spectrum to provide the basis for clinical antibacterial drugs selection .Methods The ATB microbiologi-cal system was adopted to identify the bacteria and the K-B method was used to conduct the drug sensitivity test .The detection situ-ation of PA in our hospital from January 2010 to December 2012 was performed the statistical analysis on the distribution in various specialties of pediatrics and drug resistance .Results Among 46 isolated strains of PA ,39 strains were mainly distributed in the specialties of respiration ,neonatology and pediatric intensive care unit (PICU) ,which accounted for 84 .8 % ,22 strains were isolated from sputum specimens ,which accounted for 47 .83% .The isolation rate in last three years showed the rising trend year by year , and the resistance to antibiotics was increased year after year .Conclusion PA is one of the main pathogens of clinical infection .We should strengthen its drug-resistance monitoring and use antibacterial drugs reasonably .
