The present result suggests that the CI users can rely on either temporal or spectral cues to perform tone recognition in quiet, but need both cues for tone recognition in noise. Future CI processors need to extract and encode these acoustic cues to achieve better performance in tone perception and production.

Objective: Seprase is an integral membrane serine proteinase with gelatinase activity that may be involved in cancer invasion and metastasis. However, the pathophysiologic significance of its expression in gastric cancer tissue has not been fully elucidated. Methods: Seprase expression and distribution in gastric cancer specimens obtained from 133 patients were examined by immunohistochemistry and immunoblotting. Results: Immunohistochemistry showed that in intestinal-type cancer, which includes well and moderately differentiated adenocarcinoma, seprase immunoreactivity was mainly recognized in the moderately differentiated cells and not in the well differentiated cells. In the diffuse type, which includes poorly differentiated adenocarcinoma and signet ring cell carcinoma, seprase immunoreactivity was seen mainly in cells with poor cell-to-cell junctions. The reactive pattern in the cells was different between moderately differentiated adenocarcinoma and diffuse-type carcinoma. Besides the cytoplasm, the cell membrane also apparently reacted in the former, while only the cytoplasm reacted diffusely in the latter. Seprase immunoreactivity was also recognized in endothelial cells and stromal cells especially adjacent to tumor nests. The immunoreactivity of the stromal cells was more abundant in the intestinal type than in the diffuse type, and these stromal expressions of seprase in the intestinal type correlated with the liver (13/13 = 100% of cases with metastases) or lymph node metastases (33/34 = 97% of cases with metastases). Immunoblotting showed that the levels of seprase protein were higher in intestinal-type cancer than in diffuse-type cancer. Conclusion: These results suggested that there is a difference in seprase expression between intestinal- and diffuse-type gastric cancer; this difference may reflect distinct biological features of these types of cancer.

Parents were satisfied with all domains of HRQoL. Almost all domains exhibited rapid progress over the first 3 months of CI use, with education progressing at a slower rate. This research underscores the importance of language rehabilitation by revealing that strengthening language rehabilitation could be an effective means of improving the HRQoL of children with CIs.

There is an extensive body of research about chronic pain and treatment in developed countries. In contrast there is a lack of research on this topic in developing countries including China. This study was aimed to estimate the prevalence of chronic pain in different regions of China. Data on pain and its treatment were collected from 9357 participants using questionnaires and telephone-based interviews, from 31 regions of China. Gathered data were then coded into electronic data acquisition system and descriptive and inferential statistical analysis was performed. Out of 9298 participants, the ratio of chronic pain was 31.54% with the proportion of male having chronic pain (33.86%) was higher than that of female (29.53%). The average age of participants with pain (45.02 ± 15.07 years) was higher than free-pain participants (36.19 ± 11.12 years). There were also significant differences between groups in occupation, education levels, and illness history. Proportion of patients with pain duration of 1 year was 12.104%, between 1 and 5 years was 60%, and over 10 years was 10.74%. There were 63.9% of patients with moderate pain and 36.1% with severe pain. About 43.042% of patients thought that pain resulted in sleep disorder, 38.99% thought that it causes anxiety, and about 33% thought depression and irritable bowel was the result of their pain. For the chronic pain, more than half of patients used naprapathy, cupping, and other physical therapies. Up to 2016, the ratio of pain incidence was over 30% in China. The location of pain was focused on back and upper limb. There has been a lack of proper treatment. Patients with pain had obvious economic burden, and their quality of life and psychology were significantly affected. ARTICLE HISTORY

Few studies have compared the prevalence of smoking between patients with bipolar disorder, major depressive disorder (MDD) and schizophrenia. This study examined the prevalence of smoking and its relationships with demographic and clinical characteristics, and quality of life (QOL) in patients with these psychiatric disorders. A total of 1,102 inpatients were consecutively screened. Psychopathology and QOL were measured with standardized instruments. The prevalence of current smoking in the whole sample was 16.7%; 17.5% in bipolar disorder, 10.6% in MDD and 18.5% in schizophrenia. The rates of smoking in bipolar disorder (p = 0.004, OR = 2.5, 95%CI: 1.3–4.7) and schizophrenia (p = 0.03, OR = 2.0, 95%CI: 1.06–3.8) were significantly higher than in MDD, while no difference was found between bipolar disorder and schizophrenia. Smokers had a higher mental QOL than non-smokers (p = 0.007) in MDD, but no difference was found in the other two groups. Male gender, living alone, higher personal income, older age of onset, health insurance coverage, and first episode was significantly associated with smoking in one or more diagnostic groups. Smoking appears more common in bipolar disorder and schizophrenia than in MDD in China. The figures in all disorders were lower than that reported in most of other countries.
