BACKGROUND: At present, there are some researches on the cognitive identification of Chinese characters at home or abroad, however, most of them are based on the normal and healthy people.OBJECTIVE: To investigate the processing styles of optical information on phonemic code, graphic code and semantic code of Chinese haracters between hearing-disabled and normal people.DESIGN: Retrospective, observational and compared analysis based on the hearing-disabled as research subjects and the normal as the controlled group.SETTING: Department of education in a university.PARTICIPANTS: This study was completed in Xi' an between October 2001 and April 2002. With the mean age of 17 years and half in gender, 20hearing-disabled people, who were in grade 6 to grade 8, were selected from the Second School for the Deaf and Dumb in Xi' an. Inclusion criteria: The hearing loss of people was more than or equal to 92 dB. Exclusion criteria:People with acquired hearing-disabled were excluded. At the beginning of study in primary school, they were accepted oral training and taught Chinese pinyi, but gesture was the main communicated style in their daily life. With the mean age of 15 years and half in gender, 28 normal people, who were in grade 3, were selected from the No. 99 Middle School in Xi'an.METHODS: This study showed with serial opticum. The diagnostic method was compared with the cognitive identification of the three kinds of Chinese characters between the hearing-disabled and the normal respectively.phonemic code, graphic code and semantic code between hearing-disabled characters between hearing-disabled and normal people.RESULTS: The results showed that the function of graphic code in visual processing was strongly correlated with recognition of words of Chinese characters than the phoneme code and semantic code in both the hearing-disabled and hearing children. For hearing-disabled children, the alternative was the direct access that a semantic code was produced directly from a translation of the graphic code, however, the hearing children used the strategies of grapheme-phoneme conversion rules to interpret the meaning of words.CONCLUSION: The analysis of various results showe that no significant differences of mental processing are found between the hearing-disabled and hearing children. Perhaps both the direct access and the grapheme-phoneme conversion will be a comprehensive information processing activated each other.

Objective To explore the clinical diagnosis and treatment of pediatric bridging bronchus deformity and brid-ging bronchus with pulmonary artery sling. Methods The clinical data of the 21 cases of diagnosed bronchial bridge deformity and bronchial bridge with pulmonary artery sling, the imaging findings of all the echocardiography, MSCT chest scan, enhanced CT and reconstructive image were retrospectively analyzed. Results In 21 cases, 10 were diagnosed as bronchial bridge only, among which three cases had other types of congenital heart disease;11 cases were diagnosed of pulmonary artery sling with pulmonary artery sling, among which 8 cases had other types of congenital heart disease;their average age of the 8 cases were all younger than 2 years old, except one case;most of them had the symptoms of recurrent respiratory tract infections and parox-ysmal dyspnea. According to Wells, bronchial bridge was divided into type I and typeⅡ;15 cases were type I, 6 cases were typeⅡ, 10 patients with bronchial bridge only were all type I, 5 cases of typeⅡwere associated with pulmonary artery sling. All of the 6 cases were diagnosed as typeⅡassociated with pulmonary artery sling. Conclusions Infants and young children with clini-cal recurrent respiratory tract infections should be considered the possibility of bronchus bridge deformity, and should be paid more attention to the possibility of pulmonary artery sling. MSCT plain chest scan, enhanced CT and airway reconstructive im-age are the important ways to diagnose the disease.

Objective:To explore the relationship of Syk and VEGF-C expression in breast cancer with lymph node metastasis . Methods:The expression of Syk and VEGF-C in 40 cases of breast cancer were determined using immunohistochemistry assay .Then, the positive rates of Syk and VEGF-C were compared with lymph node metastasis .Results:The expression rate of VEGF-C and Syk in breast cancer was respectively 77.5%(31/40), 37.5%(15/40).VEGF-C protein expression was not significant related with the tumor diameter (P>0.05) and histological grade (P>0.05), but was significantly associated with lymph node metastasis (P<0.05).Syk protein expression was not significant related with tumor diameter (P>0.05) and the histological grade(P>0.05), and was associated with lymph node metastasis (P<0.05).The difference of Syk and VEGF-C had statistics significance(P<0.05).Con-clusion:Syk and VEGF-C involved in the lymphatic invasion and metastasis , may be an important indicator of prognosis .

Primary immunodeficiency disease (PID) is a heterogeneous group of congenital disorders of the immune system.The impaired immune response is caused by defect of immune active cells and moleculars,which results in increased susceptibility to pathogens.Recurrent infection is the predominant presenting complaint for patients with PID.Early diagnosis,immunoglobulin replacement therapy,antimicrobial treatment,haematopoietic stem cell transplantation and gene therapy,genetic conselling and prenatal diagnosis will help to prevent and control infections in patients with PID.In addition,we should strengthen the education of paediatricians,improve awareness about PID and collaboration across different centers to advance the diagnosis and management of PID in China and save the life of patients at the maximum limit.

Objective To investigate the possible role of interleukin (IL)-10 secreted by peripheral CD+CD25+ regulatory T (Treg) cells in the formation of seroresistance state in patients with syphilis.Methods Venous blood samples were obtained from 28 serofast patients with syphilis and 28 healthy controls.Flow cytometry (FCM) was performed to determine the proportion of CD4+CD25+IL-10+ T cells in peripheral CD4+ cells,and to quantify the protein expression of IL-10 in CD4+CD25+ Treg cells.Magnetic activation cell sorting (MACS) system was used to separate CD4+CD25+ Treg cells in high purity followed by the detection of IL-10 mRNA expression with real time PCR.Results A significant increase was observed in the proportion of CD4+CD25+IL-10+ T cells in peripheral CD4+ cells,as well as protein and mRNA expression levels of IL-10 in the serofast patients with syphilis compared with the healthy controls (all P ＜ 0.01).However,no statistical correlation was observed between rapid plasma reagent (RPR) titer and any of the above three parameters in these patients (all P ＞ 0.05).Conclusion The high level of IL-10 secreted by CD4+CD25 + Treg cells may contribute to the formation of seroresistance state in patients with syphilis.

Objective To discuss the microcosmic elements and syndromes distribution of H pylori-related gastritis. [Method] Choose 100 cases, under gastroscope report, make statistics of frequency of disease nature elements and location elements, combine the nature and location for common syndromes. [Result] The H pylori-related gastritis has main disease location elements in stomach, esp. the sinuses ventriculi;the disease nature elements mainly concern hot, wet, sputum stasis, deficiency and blood stasis; the common syndromes: hot stomach, sputum and stasis blocking stomach, wet-hot accumulated in stomach, deficient stomach, wet stranding stomach and stasis blocking gastric col aterals. [Conclusion] Over the inconsistent syndromes in clinical H pylori-related gastritis, the microcosmic elements differentiation can further standardize syndromes and guide the treatment.
