OBJECTIVE: To summarize the clinicopathologic feature and diagnostic and therapeutic experience of laryngeal contact granuloma. METHOD: A retrospective study was carried out among 18 cases with this disease through careful analysis on their clinical and pathological data. RESULT: All of 18 cases were male, aged 34 to 78 years,The most common symptoms were hoarseness. In general the granuloma located on the posterior of the larynx unilaterally. The histological appearances of the lesions were typical inflammatory granuloma. Little allotype cell were found in one histologic sample. Fifteen cases received surgical excision and the recurrence rate was 60% after operation. Recidivist received operation again,4 cases among these cases received antireflux therapy after operation but 3 cases recurrences again. Among those follow-up cases(3 cases), 1 case was self-cure and other 2 cases appeared no marked change during observation period. CONCLUSION Laryngeal contact granuloma predilected the middle-aged male. The localization and appearance of the granuloma is very characteristic. The correct diagnosis can be established by clinical examination alone, but the histological examination is necessary in order to avoid missed diagnosis. There is a high recurrence rate after operation and the effect of antireflux therapy need further research.

Objective: To explore the effect of working memory intervention training on working memory and literacy of children with developmental dyslexia,so as to provide a preference for practice of the trianing of working memory among children with dyslexia. Methods: A total of 32 children with dyslexia of grade 3-5 in a primary school in Guiyang were randomly divided into two groups: the study group (n=16) and the control group (n=16),and the software of training exercises of working memory was applied to conduct interventional trainings of different durations to 2 gruops of children. Results: Through the intervention training of working memory, the scores of literacy and working memory tasks in the study group (2 217.88±252.32, 105.13±7.68) were significantly higher than those in the control group (1 907.69 ± 545.15, 96.50 ± 11.04) (t=2.06, 2.56, P<0.05). Conclusion The working memory ability of children with dyslexia can be improved by working memory intervention training for a certain period of time. The intervention effect is not only significant in the trained working memory task, but also can be extended to other untrained contents such as literacy.

OBJECTIVETo investigate the histological typing and differentiation as well as clinical manifestation and prognosis in pineal parenchymal tumors (PPTs).

METHODSThe histological typing of 21 PPTs were made by using HE staining. Synaptophysin (Syn), neuron special enolase (NSE), neurofilament (NF), neuroblastoma (NB), glial fibrillary acid protein (GFAP), cytokeratin (CK), desmin (Des) were detected in 20 cases with SP immunohistochemical staining methods. Analysis of the clinical data and follow-up were performed.

RESULTS9 pineocytomas, 4 pineoblastomas, 8 pineal parenchymal tumors of intermediate differentiation were found in 21 PPTs. Immunoreactivity to Syn, NSE, NF, GFAP, NB were in 20, 20, 14, 15, 2, while Des and CK were negative in all cases.

CONCLUSIONSPineal parenchymal tumors of intermediate differentiation were characterized by a distinctly biphasic pattern, including areas of pineocytoma and pineoblastoma, or with intermediate differentiation and transitional feature. PPTs expressed neuronic differentiation. Death rate of PPTs were higher inside 1 year after the operation.
