This study was carried out to determine the effect of the duration of chilling treatment and the lifting time of bulbs on growth of Lilium Oriental hybrids for product of cut flower in the type of forcing or semiforcing culture in Korea. "Casablanca", "Acapulco" and "Le Reve" in lilium Oriental hybrids were used in these experiment and carried out from 1999 to 2000 in Iksan, Korea. The bulbs for experiment were lifted on August 27, September 27 and October 27 and the all of them were chilled at 5±1℃ for 0,8,10,12 weeks. Development of the bulbs lifted on October 27 was superior than that of lifted bulbs on August 27 in the three cultivars. The bulbs lilted lately and chilled for a long time were sprouted more earlier and grown faster. In order to increase bulb sprouting until 100%, the duration of chilling treatment of bulbs was need for 12 weeks on August 27, 10 weeks on September 27 and above 8 weeks on October 27. The flowering according to the duration of chilling treatment and the lifting time of bulbs was same above. Consequently, the bulbs should be chilled at 5±1℃ for chilled for 10 weeks at late September and 8 weeks in producted bulbs at late October in earlyㆍMidseason variety fur product of cut flower hut bulbs of late variety should be chilled for 12 weeks at late September and 10 weeks at late October.

<P>The potential of circulating tumor DNA (ctDNA) detection in early stage lung cancer is explored. This study investigated whether bronchial washing, a minimally invasive procedure that yields fluids that may contain ctDNA, can reflect genetic profiles of primary tumors using next‐generation sequencing.</P><P>A blood‐based approach such as circulating tumor DNA remains challenging in diagnosis for early‐stage disease. Bronchial washing (BW) is a minimally invasive procedure that yields fluids that may contain tumor DNA. Therefore, we prospectively enrolled 12 patients with early‐stage non‐small cell lung cancer without endoscopically visible tumors. Somatic mutations were analyzed using ultra‐deep next‐generation sequencing in 48 paired specimens (primary tumor tissue, normal tissue, BW supernatant, and BW precipitate). In primary tumors, 130 missense mutations/indels (5–16 per patient) and 20 driver mutations (0–3 per patient) were found. Concordance of driver mutations between BW fluids and primary tumors was 95.0%. The allele frequencies for missense mutations/indels in BW supernatants significantly correlated with those in primary tumors and were higher than those in BW precipitates. These findings suggest that BW supernatants are reflective of tumor‐associated mutations and could be used for early‐stage lung cancer diagnosis.</P>

Ryu, Jeong Yeop,Eo, Pil Seon,Tian, Lulu,Lee, Joon Seok,Lee, Jeong Woo,Choi, Kang Young,Yang, Jung Dug,Chung, Ho Yun,Cho, Byung Chae Korean Society of Plastic and Reconstructive Surge 2019 Archives of Plastic Surgery Vol.46 No.1

Background Various surgical techniques have been used to correct Tessier number 7 craniofacial cleft, which involves macrostomia, ear deformity, and hemifacial microsomia. To achieve symmetrical and satisfactory results in patients with macrostomia, the authors performed a 1-mm medial overcorrection on the cleft side and evaluated the results of this procedure. Methods A retrospective medical record review of patients diagnosed with Tessier number 7 craniofacial cleft from March 1999 to February 2017 was performed. Using clinical photographs, outpatient clinic records, and operative records, information was recorded regarding concurrent congenital anomalies, postoperative complications, and follow-up. Using Photoshop CS2, the length of both sides of the lip was compared. The ratio of these lengths was calculated to evaluate lip symmetry. Results Of the patients treated at the Department of Plastic and Reconstructive Surgery at Kyungpook National University Chilgok Hospital, 11 (male-to-female sex ratio, 7:4) were diagnosed with Tessier number 7 craniofacial cleft. Concurrent congenital anomalies included skin tag, hemifacial microsomia, and cleft palate. The mean duration of follow-up was $78.273{\pm}72.219$ months and the mean ratio of the lengths of both sides of the lip was $1.048{\pm}0.071$. Scar widening occurred as a postoperative complication in some patients. No cases of wound infection, bleeding, or wound dehiscence occurred. Conclusions For the successful correction of macrostomia, plastic surgeons should consider both functional and aesthetic problems of the lip. Adequate repair of the orbicularis oris muscle, skin closure with Z-plasty, and medial overcorrection of the neo-oral commissure led to good results in our patients.

<P>Purpose: To determine the frequency and investigate possible mechanisms and prognostic relevance of minimal (<10 mm thickness) pleural effusion in patients with small cell lung cancer (SCLC). Materials and Methods: The single-center retrospective study was approved by the institutional review board of the hospital, and informed consent was waived by the patients. A cohort of 360 consecutive patients diagnosed with SCLC by using histologic analysis was enrolled in this study. Based on the status of pleural effusion on chest computed tomographic (CT) scans at diagnosis, patients were classified into three groups: no pleural effusion, minimal pleural effusion, and malignant pleural effusion. Eighteen variables related to patient, environment, stage, and treatment were included in the final model as potential confounders. Results: Minimal pleural effusion was present in 74 patients (20.6%) and malignant pleural effusion in 83 patients (23.0%). Median survival was significantly different in patients with no, minimal, or malignant pleural effusion (median survival, 11.2, 5.93, and 4.83 months, respectively; P < .001, log-rank test). In the fully adjusted final model, patients with minimal pleural effusion had a significantly increased risk of death compared with those with no pleural effusion (adjusted hazard ratio, 1.454 [95% confidence interval: 1.012, 2.090]; P = .001). The prognostic effect was significant in patients with stage I-III disease (adjusted hazard ratio, 2.751 [95% confidence interval: 1.586, 4.773]; P < .001), but it disappeared in stage IV disease. An indirect mechanism representing mediastinal lymphadenopathy was responsible for the accumulation in all but one patient with minimal pleural effusion. Conclusions: Minimal pleural effusion is a common clinical finding in staging SCLC. Its presence is associated with worse survival in patients and should be considered when CT scans are interpreted.

Jeong, Jae Hoon,Kim, Jeeyoung,Kim, Jeongwoon,Heo, Hye-Ryeon,Jeong, Jin Seon,Ryu, Young-Joon,Hong, Yoonki,Han, Seon-Sook,Hong, Seok-Ho,Lee, Seung-Joon,Kim, Woo Jin The Korean Academy of Tuberculosis and Respiratory 2017 Tuberculosis and Respiratory Diseases Vol.80 No.3

Background: Airway epithelial cells are the first line of defense, against pathogens and environmental pollutants, in the lungs. Cellular stress by cadmium (Cd), resulting in airway inflammation, is assumed to be directly involved in tissue injury, linked to the development of lung cancer, and chronic obstructive pulmonary disease (COPD). We had earlier shown that ACN9 (chromosome 7q21), is a potential candidate gene for COPD, and identified significant interaction with smoking, based on genetic studies. However, the role of ACN9 in the inflammatory response, in the airway cells, has not yet been reported. Methods: We first checked the anatomical distribution of ACN9 in lung tissues, using mRNA in situ hybridization, and immunohistochemistry. Gene expression profiling in bronchial epithelial cells (BEAS-2B), was performed, after silencing ACN9. We further tested the roles of ACN9, in the intracellular mechanism, leading to Cd-induced production, of proinflammatory cytokines in BEAS-2B. Results: ACN9 was localized in lymphoid, and epithelial cells, of human lung tissues. ACN9 silencing, led to differential expression of 216 genes. Pathways of sensory perception to chemical stimuli, and cell surface receptor-linked signal transduction, were significantly enriched. ACN9 silencing, further increased the expression of proinflammatory cytokines, in BEAS-2B after Cd exposure. Conclusion: Our findings suggest, that ACN9 may have a role, in the inflammatory response in the airway.

Background/Aims: To determine whether female smokers are more or less susceptible to the detrimental pulmonaryfunction effects of smoking when compared to male smokers among patients with lung cancer. Methods: Pack-years and pulmonary function indices were compared between 1,594 men and women with lung cancer who were smokers or had a history of smoking. Differences in individual susceptibility to smoking were estimated using a susceptibility index formula. Results: Of the patients, 959 (92.8%) men and 74 (7.2%) women were current smokers. Common histological types of lung cancer were squamous cell carcinoma, adenocarcinoma, and small cell carcinoma, among others. Women had a lower number of pack-years, forced expiratory volume in 1 second (FEV1, liters), forced vital capacity (FVC, liters), and total lung capacity (TLC, liters) compared to those of men (25.0 ± 19.2 vs. 42.9 ± 21.7 for pack-years; 1.4 ± 0.5 vs. 2.0 ± 0.6 for FEV1; 3.0 ± 0.7 vs. 2.0 ± 0.6 for FVC; 4.5 ± 0.8 vs. 5.7 ± 1.0 for TLC; all p < 0.001). The susceptibility index for women was significantly higher compared to that of men (1.1 ± 4.1 vs. 0.7 ± 1.1; p = 0.001). A significant inverse association was shown between the susceptibility index and TLC and FVC (r = -0.200 for TLC, -0.273 for FVC; all p < 0.001). Conclusions: The results suggest that the detrimental effects of smoking on pulmonary function are greater in women, as compared to those in men, among patients with lung cancer.
