Objective: To analyze the sociodemographic and clinical factors related to anxiety in patients with major depressive disorder (MDD). Methods: This study involved a secondary analysis of data obtained from the Diagnostic Assessment Service for People with Bipolar Disorders in China (DASP), which was initiated by the Chinese Society of Psychiatry (CSP) and conducted from September 1, 2010 to February 28, 2011. Based on the presence or absence of anxiety-related characteristics, 1,178 MDD patients were classified as suffering from anxious depression (n=915) or non-anxious depression (n=263), respectively. Results: Compared with the non-anxious group, the anxious-depression group had an older age at onset (t=−4.39, p<0.001), were older (t=−4.69, p<0.001), reported more lifetime depressive episodes (z=−3.24, p=0.001), were more likely to experience seasonal depressive episodes (χ2=6.896, p=0.009) and depressive episodes following stressful life events (χ2=59.350, p <0.001), and were more likely to have a family history of psychiatric disorders (χ2=6.091, p=0.014). Their positive and total scores on the Mood Disorder Questionnaire (MDQ) and the 32-item Hypomania Checklist (HCL-32) (p<0.05) were also lower. The logistic regression analysis indicated that age (odds ratio [OR]=1.03, p<0.001), a lower total MDQ score (OR=0.94, p=0.011), depressive episodes following stressful life events (OR=3.04, p<0.001), and seasonal depressive episodes (OR=1.75, p=0.039) were significantly associated with anxious depression. Conclusion: These findings indicate that older age, fewer subclinical bipolar features, an increased number of depressive episodes following stressful life events, and seasonal depressive episodes may be risk factors for anxiety-related characteristics in patients with MDD.

Treatment responses of $N_0$ stage nasopharyngeal carcinoma were firstly analyzed comprehensively to evaluate long term outcomes of patients and identify prognostic factors. A total of 610 patients with $N_0$ NPC, undergoing definitive radiotherapy to their primary lesion and prophylactic radiation to upper neck, were reviewed retrospectively. Concomitant chemotherapy was administrated to 65 out of the 610. Survival rates of the patients were calculated using the Kaplan-Meier method and compared by log-rank test. Prognostic factors were identified by the Cox regression model. The study revealed the 5-year and 10-year overall, disease-free, disease-specific, local failure-free, regional failure-free, locoregional failure-free and distant metastasis-free survival rates to be 78.7% and 66.8%, 68.8% and 55.8%, 79.9% and 70.4%, 81.2% and 72.5%, 95.8% and 91.8%, 78.3% and 68.5%, 88.5% and 85.5%, respectively. There were 192 patients experiencing failure (31.5%) after radiotherapy or chemoradiotherapy. Of these, local recurrence, regional relapse and distant metastases as the first event of failure occurred in 100 (100/610, 16.4%), 15(15/610, 2.5%) and 52 (52/610, 8.5%), respectively. Multivariate analysis showed that T stage was the only independent prognostic factor for patients with $N_0$ NPC (P=0.000). Late T stage (P=0.000), male (P=0.039) and anemia (P=0.007) were independently unfavorable factors predicting disease-free survival. After treatment, satisfactory outcome wasgenerally achieved in patients with $N_0$ NPC. Local recurrence represented the predominant mode of treatment failure, while T stage was the only independent prognostic factor for overall survival. Late T stage, male gender, and anemia independently predicted lower possibility of the disease-free survival.
The SH2 domain is crucial for function of Fyn in neuronal migration and cortical lamination

Neurons in the developing brain form the cortical plate (CP) in an inside-out manner, in which the late-born neurons are located more superficially than the early-born neurons. Fyn, a member of the Src family kinases, plays an important role in neuronal migration by binding to many substrates. However, the role of the Src-homology 2 (SH2) domain in function of Fyn in neuronal migration remains poorly understood. Here, we demonstrate that the SH2 domain is essential for the action of Fyn in neuronal migration and cortical lamination. A point mutation in the Fyn SH2 domain (FynR176A) impaired neuronal migration and their final location in the cerebral cortex, by inducing neuronal aggregation and branching. Thus, we provide the first evidence of the Fyn SH2 domain contributing to neuronal migration and neuronal morphogenesis. [BMB Reports 2015; 48(2): 97-102]

농업용 폐비닐의 재활용에 대한 무기충진재의 거동을 연구하기 위하여 한국환경자원공사 시화 및 정읍공장에서 세척된 PE fluff들을 각각 사용하였다. 먼저 PE 플러프에 무기충진재인 탄산칼슘과 칼펫을 배합비율별로 혼합하여 용융 압출을 통한 시험용 펠렛들을 제조한 후 프레스 몰딩을 거쳐 시료별로 시험용 시트들을 제작하였다. 이들 무기충진 복합재의 기계적 특성인 인장, 굴곡, Izod 충격시험을 실시하였고, 열적 특성인 열변형온도, vicat 연화온도, 용융흐름지수(MFI)를 시험 및 분석을 하였다. 또한 플라스틱 내부에서 무기충진재의 분산성 및 wetting정도를 확인하기 위하여 SEM을 통해 모폴로지를 조사하였다. 이들 결과로부터 물리적인 측면과 경제적인 관점에서 재생 PE와 무기충진재의 최적 배합비들을 얻었다. In order to study the behaviors of inorganic fillers in recycling of the waste agricultural plastic films, the washed PE fluffs from Shihwa and Jungeup Plant belonging to ENVICO were used respectively. First of all, the test pellets were manufactured by adding of inorganic fillers suchlike calcium carbonate and calpet by certain portions to PE fluffs and then the tested sheets were formed. The mechanical and thermal properties of the samples were measured and compared with others. The items measured were tensile, flexural, Izod impact, HDT, MFT, and so on. Morphologies were also investigated for various samples using the SEM. Finally, optimum ratios between recycled PE and inorganic additives were found out for the best products in physical condition as well as in economic point of view.
