Objective:To evaluate levels of intelligence in children with ADHD. Methods:A total of 129 children with ADHD and 87 normal children were evaluated with C-WISC. Results:Full-scale IQs of most children with ADHD varied between the normal and borderline range, showing incompatible scores on VIQ and PIQ. The overall levels of intelligence of children with ADHD were found be lower than normal controls. Conclusion:There was significant difference in intellectual abilities between ADHD children and normal children.

Objective: To study the relationship between inteiligence and ADHD (attention deficiency and hyperactivity disorder) . Method: 129 children with ADHD and 87 normal control were evaluated with C- WISC. Results: The IQ of some children with ADHD was in borderline range, their performance of balance between VIQ and PIQ was poor. While the controls had normal IQ. Conclusion: The IQ of children with ADHD is lower than that of normal children, especially the balance between VIQ and PIQ.

At present, there are many effective ways to achieve high performance in cluster system storage management, including server-end disk, server-end caching, local caching and cooperative caching. The cooperative caching mechanism shares caches among different clients so as to avoid expensive disk access costs and to improve overall throughput of cluster system. In this paper, a Single Copy Cooperative Cache model is proposed together with block lookup algorithm, block replacement algorithm and the consistency algorithm based on the model. Meanwhile, the prototype system of the model is implemented in PVFS file system. Finally, the performance of this system is tested in InfiniBand Framework, the result of which shows that in contrast to the original PVFS system, read performance of PVFS file system is improved by about two times, while write performance is reduced by nearly ten percent.

[ Abstract] Ischemic brain injury is closely associated w ith oxidative stress, neuron loss, and inflammatory reaction. The thioredoxin system is an important antioxidant system in human body. It plays the important roles in the process of fighting against oxidative stress damage, inhibiting apoptosis and inflammation. In recent years, the roles of thioredoxin system in cerebral ischemia have attracted more and more attention. This article review s the roles of thioredoxin in cerebral ischemia.

Objective To investigate the current situation of management of institutions of schistosomiasis prevention and control in Hubei Province so as to explore the probable competency building standards for these institutions at the county and township levels. Methods By using a combination of quantitative and qualitative methods the institutions of schistosomiasis prevention and control at county and township levels were investigated for the institutional setup staffing and fulfillment func-tions since the reform of 2004. Results Among 63 schistosomiasis endemic counties cities districts of Hubei Province there were 26 independent schistosomiasis control institutions 41.27% there were 24 institutions which were incorporated in-to CDC 38.10% and there were no institutions in 13 counties 20.63% . Among 518 endemic towns there were 299 institu-tions 57.72% . The total staffing size were 1 932 but there were 1 586 82.09% people actually working in the post and therefore there were 346 17.91% empty positions. The average rates of carrying out the six functions were 91.48%-71.19%but only 19.23%of the institutions participated in the comprehensive schistosomiasis control management project and its effect assessment. Conclusion According to the management model for schistosomiasis control institutions under the current institu-tional mechanisms we need a rigorous industry standard to constrain guide and standardize the management and capacity-building of the institutions in different historical periods.

Objective To understand the human resources of the grassroots institutions of schistosomiasis control and pre?vention so as to provide the evidence for formulating the standards of institutional capacity?building. Methods By using the combination of quantitative and qualitative methods the hierarchy of schistosomiasis control institution workers structural fea?tures of workers and benefits of workers were investigated and the results were analyzed statistically after the 2004 reform. Re?sults The constituent ratios of personnel≤30 years old 30 to 45 years old and≥45 years old were 6.8% 64.0%and 29.2%respectively with an average age of 43.1 years. For education levels 61.35%of the personnel had secondary or high school lev?els. At the city level the structural proportion of the senior professional medium professional and primary professional titles was 1.4∶5.6∶3.0 and at the county level the proportion was 0.5∶6.1∶3.4. There was 14 200 yuan per capita at the township schistosomiasis control institutions. Conclusion The technology of the personnel in schistosomiasis institutions of Hubei Prov?ince is weak the average age of personnel is old and the salary is low.

Objective To investigate the efficacy of foramen magnum decompression alone and foramen magnum decompression + Syrinx-shunt in the treatment of Chiari anomalies with syringomyelia.Methods Forty-nine Chiari anomalies with syringomyelia patients were selected,28 patients performed foramen magnum decompression alone (surgical method Ⅰ group),21 patients performed foramen magnum decompression + Syrinx-shunt (surgical method Ⅱ group).The treatment efficacy was evaluated by postoperative clinical effect and MRI review.Results In surgical method Ⅰ group,effective in 18 cases,invalid in 10 cases,the effective rate was 64.3％ (18/28).In surgical method Ⅱ group,effective in 19 cases,invalid in 2 cases,the effective rate was 90.5％(19/21).There was statistical difference (x2 =4.45,P =0.034).Conclusion Foramen magnum decompression + Syrinx-shunt is effective in the treatment of Chiari anomalies with syringomyelia,which is applicable for these patients and has a more precise consequence than foramen magnum decompression alone.

Objective:To explore the expression and clinical significance of RhoGDI2 in colorectal cancer. Methods:Immuno-histochemistry was used to identify RhoGDI2 expression in clinical samples of colorectal cancer tissues,para-tumorous tissues and lymph node metastasis tissues. The relationships between CRC clinical factors and survival were analyzed. Results: RhoGDI2 expression contributed positively with tumor progression and metastasis in clinical tissues. It was associated with the stage of the tumor,lymph node metastasis, remote metastasis, venous invasion and vessel invasion. Patients with higher RhoGDI2 expression had poorer overall survival. Conclusion:RhoGDI2 showed high expression in colorectal cancer and it was associated with the stage of the tumor,lymph node metastasis,remote metastasis, venous invasion and vessel invasion. Patients with higher RhoGDI2 expression had poorer overall survival.

Objective To explore the histopathological features of 850 patients with esophageal malignant tumor in 10 years.Methods From January 2002 to January 2012, 850 patients diagnosed with esophageal malignant tumor were enrolled.Tumor location, general type, pathological type and TNM stage were retrospectively analyzed.All the data were described as case number and percentage.Results Among the 850 cases of esophageal malignant tumor, 33 lesions (3.9％) located in the neck segment of esophagus, 119 lesions (14.0％) located in the upper segment, 44 lesions (5.2 ％) located in the upper-middle segment, 409 lesions (48.1％) located in the middle segment, 123 lesions (14.5 ％) located in the middle-lower segment, 122 lesions (14.4％) located in the lower segment.Among the 724 eases clearly diagnosed as esophageal malignant tumor by general type, the most cases were ulcer type (305 cases, 42.1％), followed by medulla type (260 cases, 35.9％), fungating type (80 cases, 11.0％) and constrictive type (70 cases, 9.7％), and the least cases were intraluminal type (nine cases, 1.2％).Among the 850 cases of esophageal malignant tumor, squamous cell carcinoma (794 cases, 93.4 ％) was the most common cytological type, followed by small cell carcinoma (19 eases, 2.2％), and the least common cytological type was adenocarcinoma (seven cases, 0.8 ％).Among the 724 cases with clear TNM staging, case number of Tis, T1, T2, T3 and T4 stage was eight (1.1％), six (0.8％), 271 (37.4％), 278 (38.4％) and 161 (22.2％), respectively.Among the 122 cases of distal esophageal carcinomas (104 cases with clear TNM staging), most cases were squamous cell carcinoma (112 cases, 91.8 ％), the others cases were adenocarcinoma (three cases, 2.5 ％), small cell carcinoma (three cases, 2.5 ％), basaloid squamous cell, adenosquamous, neuroendocrine carcinomas and carcinosarcoma (one case in each type, 0.8％).Conclusions Esophageal carcinoma was mostly located in the middle segment of in which squamous cell carcinoma was predominant while adenocarcinoma was less common.Esophageal cancer located at lower segment of esophagus is with a wide range of pathological spectrum, squamous cell carcinoma was still dominant, however, esophageal adenocarcinoma is rare.
