Objective To study the role of coping styles in the relationship between coping resources and psychosomatic health in patients with asthma. Methods 184 adult patients with asthma were investigated with General Serf-Efficacy Scale (GSES), Internality, Powerful Others, and Chance Scale (IPC), Social Support Rat-ing Scale (SSRS), Defensive Style Questionnaire (DSQ), Trait Coping Style Questionnaire (TCSQ) and Short Form 36 Health Survey Questionnaire (SF-36). Results Significant correlation between self-efficacy (r=0.356),locus of control(Ir=0.208, Pr=0.341, Cr=-0.349) ,subjective(r=0.201) and objective(r=0.189)social support, immature and middle ( r = - 0. 257 ) defensive styles and coping styles ( PCr = 0.231, NCr =-0.505 ) with Mental Component Summary (MCS) was found (all P <0.05), but Physical Component Summary (PCS) was only related to self-efficacy( r=0. 175) ,chance(r=0.150),immature(r=-0.256) and middle de-fensive Styles and negtive coping styles (all P < 0.05). PCS (t = - 5.189) and MCS (t = - 6. 758) could be predic-ted effectively by negative coping style (all P<0.01). Moreover, self-efficacy, powerful others and the use of so-cial support could had an effect on the health of patients through negative coping style. Conclusion Negative coping style could not only have a direct effect on the health of asthma patients but also be a mediator between self-efficacy, locus of control, social support and the health of patients.

Objective To explore the value of diffused optical tomography(DOT)with ultrasonography (US)in differential diagnosis of breast benign from malignant neoplasms.Methods One hundred ard twenty-three breast neoplasms from 113 patients were checked use the optical tomography image ultrasonography(OPTIMUS).The diagnosis results of the system were compared with pathological study.Two-dimensional ultrasound features in breast neoplasms were digitalizated,and HBT and SO_2 were detected by DOT.At last,synthesis diagnostic index(SDI)was obtained by both US and DOT.Statistic process was carried out in sensitivity,specificity,and the rate of accuracy respectively by US,DOT and OPTIMUS system.Results Among breast neoplasms of 123 mass studied pathologically,78 of them were benign and the rest were malignant.HBT in benign lesions(153.02±105.78)was significantly less than malignant lesions(232.95±78.22),SO_2 in benign lesions(1.0332±0.1641)was significantly elevated compared with malignant lesions(0.8794±0.1814),SDI in benign lesions(147.26±53.76)was significantly less than malignant lesions(243.98±57.27),significant differences were found between the two groups(P＜0.05).The sensitivity of differential diagnosis of breast neoplasms by the OPTIMUS system was 93.33%,the specificity was 83.33%,and the rate of accuracy was 86.99%.Conclusions OPTIMUS can improve the specificity and the rate of early diagnosis.

Objective To assess the biophysical characteristics of normal skin and inflammatory skin lesions in mild and moderate acne. Methods Seventy-five mild and moderate acne vulgaris patients were included in the study. One inflammatory lesion measuring 2.0 to 5.0 mm in diameter which occurred within 48 hours prior to the measurement was selected as the target lesion. Trans-epidermis water loss (TEWL), capacitance and a* value were measured in target lesions and lesion-adjacent normal skin. Sebum content immediately,1 and 4 (saturated) hours after face washing was also determined on target lesions and central forehead between the eyebrows. Sebum secretion rate (SSR) was calculated. Results The TEWL and SSR significantly increased in the lesion-adjacent normal skin with the increment of inflammatory lesion number (both P < 0.05), and increased in target lesions with the elevation of a* value (both P < 0.05). The target lesions exhibited a significantly higher TEWL but a lower saturated sebum content and SSR than the adjacent normal skin did (all P <0.05). Conclusions The severity of inflammatory lesions is correlated with the impaired barrier function and increased SSR in facial skin. Compared with the adjacent normal skin, inflammatory skin lesions have a reduced skin barrier function and SSR.
