It is a commonly held belief among mental health care providers that patients from the Western Pacific region with major depressive disorder (MDD) and anxiety disorders disproportionately present with somatic symptoms as opposed to emotional symptoms. Cultural norms, such as the stigma associated with psychiatric disorders, may lead members of this population to ignore the emotional aspects of these disorders or deny the presence of psychological symptoms. Empirical support is provided by the lower prevalence of these disorders in some Western Pacific nations in relation to the rest of the world. For example, MDD rates in India (9%), Japan (2%), China (2% to 4%), Malaysia (8%) and Australia (3%) are generally lower than rates in the United States (16%) and worldwide (10%). These discrepancies may be the result of missed diagnoses. Misdiagnosis is related to the increased somatization of MDD symptoms in these populations. As defined by the WHO, the Western Pacific region consists of 37 countries with a total population of 1.8 billion people (1.3 billion in China alone) with diverse cultural backgrounds and demographic profiles, which makes the issue of cultural effects on MDD diagnosis more complex.
Patients with MDD or anxiety disorders worldwide often present with somatic symptoms, which frequently accompany psychological symptoms. For example, in a recent report of pooled data from Canada, scores on the Somatic Symptoms Inventory, the 17-item Hamilton Rating Scale for Depression (HAM-D17), and the Hamilton Rating Scale for Anxiety (HAM-A) were used to evaluate the association between somatic symptoms and MDD. Of the 2,191 patients randomly enrolled in the study, 78% reported moderate-to-severe fatigue and weakness. Painful physical symptoms commonly occur in patients with anxiety disorders as well. In a European study, painful physical symptoms were reported by 28% of those without anxiety disorders and 45% of those with anxiety disorders.
Dental remineralization may be achieved by mediating the interactions between tooth surfaces with free ions and biomimetic peptides. We recently developed octuplet repeats of aspartate-serine-serine (DSS-8) peptide, which occurs in high abundance in naturally occurring proteins that are critical for tooth remineralization. In this paper, we evaluated the possible role of DSS-8 in dentin remineralization. Human dentin specimens were demineralized, exposed briefly to DSS-8 solution, and then exposed to concentrated ionic solutions that favor remineralization. Dentin nano-mechanical behaviors, hardness and elastic modulus, at various stages of treatment were determined by nanoindentation. The phase, microstructure and morphology of the resultant surfaces were characterized using grazing incidence X-ray diffraction, variable pressure scanning electron microscopy, and atomic force microscopy, respectively. Nanoindentation results show that DSS-8 remineralization effectively improves the mechanical and elastic properties of native dentin. Moreover, the hardness and elastic modulus for the DSS-8 treated dentin were significantly higher than surfaces remineralized without DSS-8.

We recently developed octuplet repeats of aspartate-serine-serine (DSS-8) peptide, which occurs in high abundance in naturally occurring proteins that are critical for tooth remineralization. In this paper, we evaluated the possible role of DSS-8 in enamel remineralization. Human enamel specimens were demineralized, exposed briefly to DSS-8 solution, and then exposed to concentrated ionic solutions that favor remineralization. Enamel nano-mechanical behaviors, hardness and elastic modulus, at various stages of treatment were determined by nanoindentation. The phase, microstructure and morphology of the resultant surfaces were characterized using the grazing incidence X-ray diffraction (GIXD), variable pressure scanning electron microscopy (VPSEM), and atomic force microscopy (AFM), respectively. Nanoindentation results show that the DSS-8 remineralization effectively improves the mechanical and elastic properties for demineralized enamel.
Objective: There are few studies of successful aging in China. This study was designed to investigate the distribution, and related factors, of successful aging in an elderly Chinese population.
Methods: A cross-sectional, community-dwelling elderly population was surveyed in Shanghai, China. We defined successful aging based on a multi-dimensional model. Correlates of successful aging were explored through the Shanghai Successful Aging Project Questionnaire, which includes sociodemographic questions, and a battery of standardized instruments, including the Chinese version of the Mini-mental State Examination, activities of daily living, and the Life Satisfaction Index A (LSIA).
Results: The rate of successful aging was 46.2% [95% confidence interval (CI) 43.6–48.7] among people aged 65 or above, and the rate for males was higher than that for females. The rate was much lower for those aged 85 years or over (9.4%). Logistic regression analysis suggested that female gender and older age were unfavorable factors for successful aging. A higher score on the LSIA, more leisure activities and being currently married related to successful aging.
Conclusion: The rate of successful aging in Shanghai, China is similar to that found in studies from western countries. There are some potentially modifiable factors that may relate to successful aging.
