  • Objective: To retrospectively review the clinical characteristics and analyze the prognostic factors of Chinese patients with pulmonary neuroendocrine tumors. Materials and Methods: The clinical data of 176 patients with pulmonary neuroendocrine tumors in Chinese PLA General Hospital from Mar., 2000 to Oct., 2012 were retrospectively analyzed. The parameters were evaluated by univariate and multivariate analysis, including the gender, age, smoking history, family history, TNM staging, localization (central or peripheral), tumor size, nodal status, histological subtype and treatment (operation or non-operation). Results: There were 23 patients with typical carcinoids (TC) (13.1%), 41 with atypical carcinoids (AC) (23.3%), 10 with large cell neuroendocrine carcinoma (LCNEC) (5.7%) and 102 with small cell lung cancer (SCLC) (57.9%). The median follow-up time was 64.5 months for AC, 38 months for LCNEC and 27 months for SCLC. The typical carcinoid censored data was 18 (more than 50% of the patients), so the median follow-up time was not obtained, and actuarial 5-year survivals for TC, AC, LCNEC and SCLC were 75.1%, 51.7%, 26.7% and 38.8%, respectively. COX univariate analysis revealed that the age (P=0.001), histological subtype (P=0.005), nodal status (P=0.000), treatment (P=0.000) and TNM staging (P=0.000) were the prognostic factors of the patients with pulmonary neuroendocrine tumors, whereas its multivariate analysis showed that only the age(P=0.001), TNM staging (P=0.002) and treatment (P=0.000) were independent prognostic factors. Conclusions: Radical surgery remains the treatment of choice, and is the only curative option. The age, TNM staging and treatment are confirmed to be the independent prognostic factors in multivariable models for pulmonary neuroendocrine tumors.

  • Objective: To identify the initial chest computed tomography (CT) findings and clinical characteristics associated with the course of coronavirus disease 2019 (COVID-19) pneumonia. Materials and Methods: Baseline CT scans and clinical and laboratory data of 72 patients admitted with COVID-19 pneumonia (39 men, 46.2 ± 15.9 years) were retrospectively analyzed. Baseline CT findings including lobar distribution, presence of ground glass opacities, consolidation, linear opacities, and lung severity score were evaluated. The outcome event was recovery with hospital discharge. The time from symptom onset to discharge or the end of follow-up (for those remained hospitalized) was recorded. Data were censored in events such as death or discharge without recovery. Multivariable Cox proportional hazard regression was used to explore the association between initial CT, clinical or laboratory findings, and discharge with recovery, whereby hazard ratio (HR) values < 1 indicated a lower rate of discharge at four weeks and longer time until discharge. Results: Thirty-two patients recovered and were discharged during the study period with a median length of admission of 16 days (range, 9 to 25 days), while the rest remained hospitalized at the end of this study (median, 17.5 days; range, 4 to 27 days). None died during the study period. After controlling for age, onset time, lesion characteristics, number of lung lobes affected, and bilateral involvement, the lung severity score on baseline CT (> 4 vs. ≤ 4 [reference]: adjusted HR = 0.41 [95% confidence interval, CI = 0.18-0.92], p = 0.031) and initial lymphocyte count (reduced vs. normal or elevated [reference]: adjusted HR = 0.14 [95% CI = 0.03-0.60], p = 0.008) were two significant independent factors that influenced recovery and discharge. Conclusion: Lung severity score > 4 and reduced lymphocyte count at initial evaluation were independently associated with a significantly lower rate of recovery and discharge and extended hospitalization in patients admitted for COVID-19 pneumonia.

  • Kim, Yong-Hwan is a one of the South Korean major cartoonists between 1940s and 1960s. Kim, Yong-Hwan drew a variety of genres from children's cartoon to current-affair cartoon. Furthermore, Kim, Yong-Hwan took the lead in publishing cartoon magazine and newspaper after the Independence, and has been highly appreciated as a pioneer of Korean cartoon. Kim, Yong-Hwan created many works in the fields of illustrations, Oriental painting, history painting, caricature, etc. After going study for painting to Japan, Kim, Yong-Hwan made his debut as an illustrator called Kita Koji in Japan. However, not much is known about his works in Japan, only there is a simple data about his Japan period and some pieces of illustration during Japan years. In this paper, I examined in detail about Kim, Yong-Hwan's work activity in Japan which has been little known in Korea for a long time. I studied on illustrations in magazines and books which he drew in the name of Kita Koji, on the basis of the data of the National Diet Library of Japan. I could know that Kim, Yong-Hwan worked actively in a diversity of publishers and magazines. In addition, I could realize that many magazines in which Kim, Yong-Hwan drew illustrations were very popular ones. This demonstrates that Kim, Yong-Hwan was much recognized in Japan for his talent. However, a large number of Kim, Yong-Hwan's illustrations were published from late 1930s to mid-1940s. This period was the years that Japan concentrated all her energy for World War II. All the publishing were severely censored during this period. A majority of publishing in this period supported Japanese militarism, and glorified Japan's war policy. Kim, Yong-Hwan's illustrations were no exception, too. It was really sorry about his activity during his Japan period. This essay means a lot to a field of cartoon studies in terms of a collection of materials during Kim, Yong-Hwan's Japan period. Besides, I think that henceforth, this paper can contribute to a follow-up study on Kim, Yong-Hwan' work and his broad background.
