Silkworm pupae are a source of edible lipid with a high content of unsaturated fatty acids (UFAs) (70% of total lipid content) and are becoming a focus of pharmaceutical and dietary research in the functional oil field. To study the nutritional value of different silkworm strains, principal component analysis (PCA) was used to establish a mathematical model and cluster analysis on silkworm pupae lipid (SPL) in 90 strains based on Z-score. Single-factor correlation analysis indicated that the PUFAs content was significantly positively correlated with the α-linolenic acid (ALA) (ρ=0.98) and negatively correlated with the oleic acid (OA) (ρ=−0.73) contents, and comprehensive of principal components mathematical model (PC =0.148ZX1 +0.00 2ZX2 −0.197ZX3 −0.338ZX4 +0.220ZX5 +0.304ZX6 +0.314ZX7, ZXi is the standard score (Z-score) of X1, which was calculated as follow: ZXi = (Xi −−X )/S, where X1: palmitic acid, X2: palmitoleic acid, X3: stearic acid, X4: OA, X5: linoleic acid, X6: ALA, X7: PUFAs.−X is the arithmetic mean content of variable i, and S is the standard deviation of variable i for all samples included in the analysis.) showed the amount of ALA and PUFAs were the key factors determining the nutritional value of the pupae lipid. Cluster analysis on the composite scores calculated by the model of the principal component divided the 90 strains into three groups. A cluster of 6 strains (XHR, XIFF, ZX, YT, YO and BTN) with the best nutritional value was characterized by high contents of ALA and PUFAs and a low content of oleic acid.

Background and Purpose Five single-nucleotide polymorphisms (SNPs) (rs4379368, rs10504861, rs10915437, rs12134493 and rs13208321) were recently identified in a Western population with migraine. These migraine-associated SNPs have not been evaluated in a Han Chinese population. This study investigated the associations of specific SNPs with migraine in a Han population. Methods This was a case-control study of Han Chinese residing in Fujian Province. Polymerase chain reaction—restriction-fragment-length polymorphism analysis and direct sequencing were used to characterize the relationships of SNPs in a control group of 200 subjects and in a migraine group of 201 patients. Results The frequencies of the five SNPs did not differ between patients with migraine and healthy non migraine controls. However, subgroup analysis indicated certain SNPs were more strongly associated with migraine with aura or migraine without aura than with controls. The CT genotype of rs4379368 was more common in migraine patients with aura (75%) than in migraine patients without aura (47.9%) and controls (48.5%) (p<0.05), and the TT genotype of rs10504861 was more common in migraine patients with aura than in controls (8.3% vs. 0.5%) (p<0.05). Meanwhile, the CC genotype of rs12134493 was less common in migraine patients without aura than in controls (80.6% vs. 88%) (p<0.05). Conclusions Our findings suggest that the rs4379368 and rs10504861 SNPs are markers for susceptibility to migraine with aura and that rs12134493 is a marker for the risk of migraine without aura in this Han population. Future studies should further explore if these associations vary by ethnicity.

Purpose: This study aimed to assess possible interactive effects of coping styles and psychological stress on depression and anxiety symptoms in Chinese women shortly after diagnosis of breast cancer. Methods: Four hundred and one patients with breast cancer were face-to-face interviewed by trained research staff according to a standardized questionnaire including information on socio-demographic characteristics, psychological stress, coping styles, and anxiety and depressive symptoms. Interactive effects were assessed by hierarchical multiple regression analyses. Results: There were significant associations of the four domains of psychological stress with anxiety and depressive symptoms except for the relationship between "worrying about health being harmed" and depressive symptoms. "Abreaction coping behavior" and "escaping coping behavior" significantly increased the level of both anxiety and depressive symptoms; whereas an "active coping style" reswulted in significant decrease. The interaction of "active coping behavior" with "worrying about health being harmed" significantly increased the risk of the anxiety symptoms, while adopting "self-relaxing coping behavior" was associated with significant decrease. The interaction of "worry about daily life and social relationship being restricted" with "escaping coping behavior" significantly increased the risk of the depressive symptoms. Conclusions: The results of this study suggest that certain coping styles might moderate the association of psychological stress with anxiety and depressive symptoms in Chinese women with breast cancer.
