Chinese expert consensus on imaging diagnosis of drug-resistant pulmonary tuberculosis.

Tuberculosis (TB) remains one of the major infectious diseases in the world with a high incidence rate. Drug-resistant tuberculosis (DR-TB) is a key and difficult challenge in the prevention and treatment of TB. Early, rapid, and accurate diagnosis of DR-TB is essential for selecting appropriate and personalized treatment and is an important means of reducing disease transmission and mortality.

Differences in pulmonary nodular consolidation and pulmonary cavity among drug-sensitive, rifampicin-resistant and multi-drug resistant tuberculosis patients: the Guangzhou computerized tomography study.

Background: Pulmonary nodular consolidation (PN) and pulmonary cavity (PC) may represent the two most promising imaging signs in differentiating multidrug-resistant (MDR)-pulmonary tuberculosis (PTB) from drug-sensitive (DS)-PTB. However, there have been concerns that literature described radiological feature differences between DS-PTB and MDR-PTB were confounded by that MDR-PTB cases tend to have a longer history. This study seeks to further clarify this point.

Toward an Expert Level of Lung Cancer Detection and Classification Using a Deep Convolutional Neural Network.

Background: Computed tomography (CT) is essential for pulmonary nodule detection in diagnosing lung cancer. As deep learning algorithms have recently been regarded as a promising technique in medical fields, we attempt to integrate a well-trained deep learning algorithm to detect and classify pulmonary nodules derived from clinical CT images.

Materials And Methods: Open-source data sets and multicenter data sets have been used in this study.

Clinical treatment of pandrug-resistant bacterial infection consulted by clinical pharmacist.

Objective: Pandrug-resistant (PDR) bacterial infections are associated with considerable prolongation of hospitalization and mortality in clinical practice.

Method: This case-series study was conducted during a 3-year period from 2011 to 2013. A total of 30 PDR patients consulted by clinical pharmacist were recorded to evaluate the anti-infection treatment.

CT-guided radiofrequency ablation after with transarterial chemoembolization in treating unresectable hepatocellular carcinoma with long overall survival improvement.

Purpose: To assess the time to disease progression (TTP), long-term survival benefit and safety of patients with unresectable hepatocellular carcinoma (HCC) treated with computed tomography (CT)-guided radiofrequency ablation (RFA) with transarterial chemoembolization chemoembolization (TACE).

Methods: This study was approved by the institutional review board. We reviewed the records of patients with intermediate and advanced HCC treated with CT-guided RFA with TACE between January 2000 and December 2009.

[Value of 16-slice spiral CT in the diagnosis of tumor-like bronchial tuberculosis].

Objective: To evaluate the value of 16-slice multi-detector CT (MDCT) in the diagnosis of tumor-like bronchial tuberculosis.

Methods: Twenty-five patients with tumor-like bronchial tuberculosis underwent 16-slice CT scanning and the CT data were analyzed.

Results: Tumor-like bronchial tuberculosis were classified into 4 types according to the imaging features, namely intra-lumen nodule, intra-lumen mass, compression from outside of the bronchial lumens, and lung hilum mass.

Relationship between acute organophosphorus pesticide poisoning and damages induced by free radicals.

Objective: To study the relationship between abnormal reactions of free radicals in bodies of patients with acute organophosphorus pesticide poisoning (AOPP) and damages induced by free radicals.

Methods: 58 AOPP patients and 58 healthy adult volunteers (HAV) were enrolled in an independent samples control design, in which spectrophotometric methods were used to determine the concentrations of nitric oxide (NO) and lipoperoxides (LPO) in plasma, and LPO in erythrocytes, vitamin C (VC), vitamin E (VE) and beta-carotene (beta-CAR) in plasma as well as activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px) and acetylcholinesterase (AChE) in erythrocytes.

Results: Compared with the average values of every biochemical parameter in the HAV group, the average values of LPO in plasma and in erythrocytes, and NO in plasma in the AOPP group were significantly increased (P = 0.
