ABSTRACT
Objective To explore the epidemic situation of nontuberculous Mycobacteria in both Yuexiu and Zhuhai districts. Methods Mycobacterium tuberculosis culture and strain identification were conducted in suspected smear-positive tuberculosis patients who had visited our clinics at Yuexiu and Haizhu districts in Guangzhou during the period of 2010 to 2012. Results 2 014 sputum samples were identified as NTM and MTC, 1 630 samples were MTC (80.9%), and 384 samples were NTM (19.1%). The isolated rate for NTM from 2010 to 2012 was 17.6%, 17.1% and 21.2%, respectively. 79 strains of 384 NTM were identified; the rapid-growing mycobacterium was 50.6%, and the slow-growing mycobacterium was 49.4%. Conclusions The sputum-isolated rate of NTM for the suspected tuberculosis patients was 19.1% in Yuexiu and Haizhu districts in Guangzhou. For the smear-positive pulmonary tuberculosis patients who respond to treatment poorly , we should pay attention to NTM lung disease.
ABSTRACT
Objective To study the feasibility of in vitro release of γ-interferon tests (IGRA) in screening of tuberculosis for children with close TB contacts. Methods 185 children with close TB contacts were detected by IGRA at the pediatric clinic in our hospital. Results In IGRA-positive group, the rate of strong positive PPD (PDD≥15 mm) was 50.9%, which was higher than 9.1% in IGRA-negative group (X2 =37.263, P < 0.00). The morbidity rate for children with close TB contacts was 30.2% in IGRA-positive group, and it was significantly higher than 3.0% in IGRA-negative group (X2 = 28.928, P < 0.00). The sensitivity was 80% and the specificity was 77.6% for IGRA screening in children who had close contacts with TB patients. The sensitivity would be 95.0%, as the test was combined with PPD test. Conclusions IGRA screening in children with close TB contacts can increase the detection rate of tuberculosis and reduce imaging screening.
ABSTRACT
ABSTRACT:Strongyloides stercoralis is an opportunistic parasitic nematode ,whose larvae can invade the lung ,brain ,liv‐er ,kidney and other organs of hosts and cause strongyloidiasis .The infection opportunity of strongyloidiasis increased with raised living standard ,changed lifestyle and family pets .So far ,the relevant domestic researches of strongyloidiasis are limited in case reports and epidemiological investigation ,but researches involving biological characteristics ,immune phenomenon and protective immune response in humans are still very little .Based on the references ,this review summarizes recent findings in morphology ,life cycle ,pathogenicity ,epidemiology ,immunology ,diagnosis and prevention of S .stercoralis for raising the awareness of strongyloidiasis .
ABSTRACT
<p><b>OBJECTIVE</b>To compare the clinical characteristics of rifampin-dependent (R-dependent Mycobacterium tuberculosis) and rifampin-resistant (R-resistant Mycobacterium tuberculosis) patients with pulmonary tuberculosis.</p><p><b>METHODS</b>The clinical data including the demographic data, age groups, course of disease, history of chemotherapy with anti-TB drugs, and results of drug susceptibility test were collected from 61 cases of R-dependent pulmonary tuberculosis and 148 cases of R-resistant pulmonary tuberculosis treated between October, 2008 and January, 2012.</p><p><b>RESULTS</b>Most of the R-dependent and R-resistant patients were between 30 and 44 years of age. The R-dependent patients included 12 receiving the first treatment patients and 49 with previous treatments, and the R-resistant patients included 11 without and 137 with previous treatments. The multi-drug resistant rate was 80.3% in R-dependent group, as compared to 92.6% in R-resistant group.</p><p><b>CONCLUSION</b>Most of the patients infected with R-dependent Mycobacterium tuberculosis are young or middle-aged, often having serious disease conditions. Detecting rifampin dependence is important for patients with initial treatment failure. Multi-drug resistance therapy guideline should be applied to patients infected with R-dependent Mycobacterium tuberculosis to improve the cure rate.</p>

ABSTRACT
A survey into the current situation of 28 hospital libraries in the Beijing area has led to the discovery of a number of problems in the construction of hospital libraries in the Beijing area, including shortage of specialized personnel, non-adaptation to changes in information resources, and lack of due attention to the work in hospital libraries. In light of this, attention ought to be paid to the following three aspects in the work of hospital libraries: ① attaching importance to the cultivation and introduction of specialized personnel; ② identifying the right starting point and providing individualized services; ③using funds in a rational manner.
