The proliferation, migration, cytokine release, and contraction of airway smooth muscle cells are key events in the airway remodeling process that occur in lung disease such as asthma, chronic obstruction pulmonary disease, and cancer. These events can be modulated by a number of factors, including cigarette smoke extract (CSE). CSE-induced alterations in the viability, migration, and contractile abilities of normal human airway cells remain unclear. This study investigated the effect of CSE on cell viability, migration, tumor necrosis factor (TNF)-${\alpha}$ secretion, and contraction in normal human bronchial smooth muscle cells (HBSMCs). Treatment of HBSMCs with 10% CSE induced cell death, and the death was accompanied by the generation of reactive oxygen species (ROS). CSE-induced cell death was reduced by N-acetyl-l-cysteine (NAC), an ROS scavenger. In addition, CSE reduced the migration ability of HBSMCs by 75%. The combination of NAC with CSE blocked the CSE-induced reduction of cell migration. However, CSE had no effect on TNF-${\alpha}$ secretion and NF-${\kappa}B$ activation. CSE induced an increase in intracellular $Ca^{2+}$ concentration in 64% of HBSMCs. CSE reduced the contractile ability of HBSMCs, and the ability was enhanced by NAC treatment. These results demonstrate that CSE treatment induces cell death and reduces migration and contraction by increasing ROS generation in normal HBSMCs. These results suggest that CSE may induce airway change through cell death and reduction in migration and contraction of normal HBSMCs.

The risk of venous thromboembolism (VTE) is known higher in cancer patients and lower incidence in the east country. This study was conducted in order to check the incidence rate of VTE in the Korean high risk patients who are treated in the intensive care unit (ICU), and to verify the correlation of the incidence of VTE and prophylaxis methods. This study was conducted as a retrospective study for 492 cancer patients from April 2011 to December 2014. According to the medical records of subjects, their prophylaxis methods and the incidence of VTE were surveyed and then correlation of them was investigated with statistical methods. 385 patients met the inclusion criteria. VTE occrred in 17 of them (4.4%). The prophylaxis methods are consisted of medical method (136 subjects), mechnical method(33 subjects), and medical & mechnkcal method (124 subjects). VTE occurred in 14 patients (4.8%) from 293 patients (76%) who were given at least one prophylaxis method. From all of 93 patients without prophylaxis, three patients experienced VTE (3.3%). The target patients were high risk in VTE, but the incidence rate of VTE was lower than reported in previous studies. The reason of this is considered that more active prophylaxis intervention was applied to the subjects because of their high risk status. As a result, it is considered that in the high risk patients, it would be effective to apply active and complex prophylaxis intervention for the prevention of VTE.

Background: A sians were known to have a relatively lower incidence of venous thromboembolism (VTE), and there is insufficient evidence to suggest a specific D-dimer threshold level for screening VTE in patients with acute stroke. Methods: We prospectively enrolled patients with acute ischemic stroke admitted to Jeju National University Hospital. The inclusion criteria were: 1) aged ${\geq}18$ years, 2) admission within seven days of symptom onset, and 3) an initial National Institute of Health Stroke Scale (NIHSS) score >1 for the affected lower limb. Ultrasound scans of the lower limbs and plasma D-dimer assays were performed on days 7-14 and 15-28 after stroke onset. Results: Of 285 patients admitted during the study period, 52 patients met inclusion criteria (mean age 74.5, male 40.4%, median initial NIHSS score 12, and unable to walk unassisted at discharge 76.9%). During 7-14 days, 23 of 52 patients (44.2%) had a D-dimer level above 1.57 mg/L, and 9.6% had a level above 5.50 mg/L. Proximal deep vein thrombosis (DVT) was detected in 3 patients (5.8%, 95% confidence Interval 1.2-16.0%) on ultrasound examination. All DVTs were found in elderly female patients with severe leg weakness. No patient was diagnosed with pulmonary embolism during the study period. Conclusion: The incidence of VTE seems to be very low among Korean patients with acute ischemic stroke. Advanced age, female sex, and severe leg weakness were important risk factors for developing DVT in this study.

This review investigated the effectiveness and safety of acupotomy treatment for scoliosis. There were 7 online databases used in the search from inception to March 17, 2021, for randomized controlled trials of the use of acupotomy in patients with scoliosis. The Cochrane risk-of-bias tool was used to assess the methodological quality of the studies included (n = 12). A quantitative synthesis of the randomized controlled trials was performed using RevMan Version 5.3. The effect sizes of studies were presented as mean differences for continuous outcomes and risk ratios for dichotomous outcomes, with a 95% confidence interval. As part of combined therapy, acupotomy was reported to significantly improve Cobb's angle compared with other treatments. Likewise, the Visual Analog Scale score, the Oswestry Disability Index score, and pulmonary function were also reported to be improved following acupotomy combination therapy. Although 5 studies mentioned the criteria for reporting adverse events, only 1 study reported adverse events. In conclusion, acupotomy may be an effective treatment for scoliosis. However, the small number, and heterogeneity of the included studies, as well as the poor methodological quality, indicate that higher-quality studies should be conducted to verify the effectiveness and safety of acupotomy treatment for scoliosis.

Background: An accurate diagnosis in patients with interstitial lung diseases (ILDs) by multidisciplinary discussion (MDD) based on histopathologic information is essential for optimal treatment. Transbronchial lung cryobiopsy (TBLC) has increasingly been used as a diagnostic alternative to surgical lung biopsy. This study aimed to evaluate the appropriate methods of TBLC in patients with ILD in Korea. Methods: A total of 27 patients who underwent TBLC were included. TBLC procedure details and clinical MDD diagnosis using TBLC histopathologic information were retrospectively analyzed. Results: All procedures were performed under general anesthesia with the fluoroscopic guidance in the operation room using flexible bronchoscopy and endobronchial balloon blocker. The median procedure duration was less than 30 minutes, and the median number of biopsies per participant was 2. Most of the bleeding after TBLC was not severe, and the rate of pneumothorax was 25.9%. The most common histopathologic pattern was alternative (48.2%), followed by indeterminate (33.3%) and usual interstitial pneumonia (UIP)/probable UIP (18.5%). In the MDD after TBLC, the most common diagnosis was idiopathic pulmonary fibrosis (33.3%), followed by smoking-related ILD (25.9%), nonspecific interstitial pneumonia (18.6%), unclassifiable-ILD (14.8%), and others (7.4%). Conclusion: This first single-center experience showed that TBLC using a flexible bronchoscopy and endobronchial balloon blocker with the fluoroscopic guidance under general anesthesia may be a safe and adequate diagnostic method for ILD patients in Korea. The diagnostic yield of MDD was 85.2%. Further studies are needed to evaluate the diagnostic yield and confidence of TBLC.

Purpose: The purpose of this paper is to report the improvement of a patient with amyotrophic lateral sclerosis after long-term combined Korean medical treatment. Methods: A patient diagnosed with amyotrophic lateral sclerosis was treated with herbal medicine, acupuncture, pharmacopuncture, moxibustion, and rehabilitation for four separate hospital stays. To evaluate their respiratory discomfort and limb weakness, we used Manual Muscle Testing, the Pulmonary Function Test, and the Korean Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised. Results: The weakness of the muscles of the lower extremities and respiratory function was improved. Conclusion: We consider that combined Korean medicine treatments might be an effective treatment for muscle weakness and respiratory discomfort of amyotrophic lateral sclerosis. To verify the effectiveness of these treatments, further research is required.

Purpose : Lung cancer induces a decrease in physical activity and a deterioration of respiratory ability. Exercise is an effective treatment to reduce side effects of anti-cancer treatments, also influence the survival and successful rehabilitation in lung cancer patients. However, there is insufficient evidence to show which period is the most effective to apply exercise for lung cancer patients. Therefore, this study was conducted to evaluate the efficacy of exercise-based interventions before and after surgery. Methods : Clinical trials (CTs) and randomized controlled trials (RCTs) reported in PubMed database were investigated. The trials investigated in this study were published for 10 years before August 20, 2022. The risk of bias was judged according to the Cochrane guideline. The materials included in this meta-analysis were 6-minute walk test (6MWT), pulmonary function, and quality of life (QOL). Results : 1 CT and 9 RCTs were selected in current study. In the meta-analysis, exercise increased 6MWT in preoperation (mean difference [MD] 29.49; 95 % confidence interval [CI] .99 to 57.99; p=.04; I²=0 %), 3 months postoperation (MD 54.97; 95 % CI 31.85 to 78.09; p<.001; I²=45 %) and 6 months postoperation (MD 85.59; 95 % CI 45.06 to 126.12; p<.001; I²=47 %). Exercise, also enhanced the lung function such as FEV₁/FVC (%) in postoperation (MD 7.64; 95 % CI 6.26 to 9.02; p<.001; I²=19 %). Additionally, exercise improved QOL, such as preoperative EORTC-QLQ-C30-LC13 in mental function (MD 3.21; 95 % CI .64 to 5.79; p=.01; I²=0 %) and postoperative SF-36 in mental component summary (MD 9.24; 95 % CI 4.94 to 13.54; p<.001; I²=0%). Conclusion : These results indicate that exercise-based intervention can elevate the ability to exercise and the mental componentof QOL within 3 months.
