Automated detection and quantification of COVID-19 pneumonia: CT imaging analysis by a deep learning-based software.

Background: The novel coronavirus disease 2019 (COVID-19) is an emerging worldwide threat to public health. While chest computed tomography (CT) plays an indispensable role in its diagnosis, the quantification and localization of lesions cannot be accurately assessed manually. We employed deep learning-based software to aid in detection, localization and quantification of COVID-19 pneumonia.

Infection Control Precautions and Care Delivery in Hemodialysis Unit during Coronavirus Disease 2019 Outbreak: A Case Series.

Background: With an estimated basic reproductive number of 3.77, the Coronavirus Disease 2019 (COVID-19) continues to spread. It is urgent to exert adequate efforts for the management of dialysis patients, caregivers, and healthcare personnel (HCP).

MiR-23a-5p modulates mycobacterial survival and autophagy during mycobacterium tuberculosis infection through TLR2/MyD88/NF-κB pathway by targeting TLR2.

Autophagy plays a pivotal role in activating the antimicrobial host defense against Mycobacterium tuberculosis (M.tb.).

ZC3H12D attenuated inflammation responses by reducing mRNA stability of proinflammatory genes.

Infection in airspaces and lung parenchyma may cause acute lung injury and multiple organ dysfunction syndrome due to acute inflammatory response, leading to organ failure and high mortality. ZC3H12D has been shown to modulate Toll-like receptor signaling. This study aimed to investigate the change of ZC3H12D during acute lung injury and its role in inflammation processes.

Novel bronchoscopic balloon dilation for patients with bronchostenosis caused by bronchial tuberculosis: a case report.

Introduction: Bronchoscopic balloon dilation is a common method in the treatment of bronchostenosis but it is not an effective treatment due to its short dilating time (3 minutes) and low pressure (<3atm). Until recently, the reported highest dilating pressure was ≤6atm; however, this is not enough pressure to dilate a bronchostenosis because of the resistance of the bronchus. We hypothesized that higher dilating pressure (up to 14atm) with longer dilating time (40 minutes) may make bronchoscopic balloon dilation treatment more effective according to the blood vessel dilating method.

Therapeutic effects of sequential therapy by electric coagulation, cryotherapy and balloon dilation with an electronic video bronchoscope.

The aim of the current study was to retrospectively analyze clinical data concerning bronchostenosis or bronchial obstruction caused by endobronchial tuberculosis. Fifty-six cases were subjected to bronchoscopy and chest computed tomography to assess the prognosis of bronchostenosis and bronchial obstruction. Based on reliable and effective anti-pulmonary tuberculosis therapy, these conditions were treated sequentially by electric coagulation, cryotherapy and balloon dilation with an electronic video bronchoscope during outpatient consultation or inpatient hospitalization.

Overexpression of STAT3 potentiates growth, survival, and radioresistance of non-small-cell lung cancer (NSCLC) cells.

Objective: Activation of signal transducer and activator of transcription 3 (STAT3) play important roles in tumorigenesis and tumor progression. The overexpression of STAT3 has been found in various malignancies including non-small-cell lung carcinoma (NSCLC). The purpose of this study was to explore the correlation between overexpression of STAT3 gene and growth, survival, and radiosensitivity of NSCLC cells.

[The application of combined interventional procedures for the management of intractable central airway stenosis].

Objective: to evaluate the application of combined five interventional procedures in the management of intractable central airway stenosis.

Methods: clinical manifestations and pulmonary functions of 138 patients with intractable central airway stenosis were evaluated. Five interventional procedures, including high-frequency electrotome, argon plasma coagulation (APC), cryotherapy, stent placement and high-pressure balloon dilatation, were used in this study.

[Joint application of 7 interventional pulmonology methods in early diagnosis of lung cancer].

Objective: To evaluate the combination of 7 interventional pulmonology methods in early diagnosis of lung cancer.

Methods: A total of 467 patients with thoracic and pulmonary lesions (include hilum pulmonis lymphadenectasis, mediastinal lymphadenectasis, pulmonary scobination, lump, lamellar infiltration, small amount of pleural fluid and pleural scobination) had negative results via exfoliative cytology, bacteriology and routine bronchoscopy. All these patients had ultrathin bronchoscopy with biopsy and brushing.

[Efficacy and safety of argon plasma coagulation in the treatment of obstructive tracheobronchial stenosis].

Objective: To evaluate the efficacy and safety of argon plasma coagulation (APC) in the treatment of large airway obstruction.

Methods: Totally 389 patients with treacheobronchial stenosis were treated with APC (ARCO3000 type) by bronchoscopy. The stenoses were caused by carcinomas (203 cases, 52.

Effect of anti-tuberculosis therapy on liver function of pulmonary tuberculosis patients infected with hepatitis B virus.

Aim: To observe the effect of anti-tuberculosis therapy on liver function of pulmonary tuberculosis patients with hepatitis B virus (HBV) infection, and to compare the differences of liver function by two treatments of anti-tuberculosis.

Methods: Forty-seven TB patients with HBV infection and 170 TB patients without HBV infection were divided into HPBE(S) and HLAMKO treatment groups. Liver function tests before and after the treatments were performed once in 2 wk or monthly, and their clinical manifestations were recorded.
