It was found that the Lao Shan polsaccharide P, one of the chemical components of polystictus versicolor increased the number of acetylated low density lipoprotein ( acLDL ) receptorsin the macrophages and stimulated the binding, internalization and degradation of (125I ) acLDL by the macrophages in vitro. The effect on cell degradation of ( 125I ) acLDL was dose-effect. At 100?g/ ml of the Lao Shan polysaccharide P, the effect was maximum and the degradation of ( 125I ) acLDL increased 77% ( P

How to select endocrine agents for patients with ER-positive/ Her-2 -positive breast cancer has been a difficult question. Increasing evidences shows a consistent results that an association between Her-2 overexpression and poor response of endocrine treatment, tamoxifen and the third generation aromatase inhibitors has the similar poor efficacy. The treatment strategy for such patients should prefer chemotherapy alone or in combination with trastuzumab, and endocrine therapy combining with trastuzumab may be the development strategy.

Gemcitabine is important pyrimidine antimetabolites drug. Ribonucleotide reductase is oneof its targets whose overexpression has been observed in several gemcitabine- resistant cell lines. Meanwhile,the NSCLC patients with high RRM1 expression levels have a relatively poor survival when treated with gem-citabine. To this day, the relationship between RRM1 expression levels in peripheral blood mononuclear cellsand gemcitabine is still uncertain and it deserves further research.

BACKGROUND: Dyslexia is the most common in the study of learning disabilities, it can affect various aspects of children, including behaviors,cognition, emotion, social adaptation, etc., and seriously block their obtaining of knowledge and improvement of ability in children.OBJECTIVE: To study the changing law of regional cerebral blood oxygenation in children with Chinese dyslexia in the process of recognizing Chinese characters, and investigate the neurophysiological basis of dyslexia in children.DESIGN: A case-control study.SETTING: Department of Child and Adolescent Health and Maternal Care, School of Public Health, Tongji Medical College, Huazhong University of Science and Technology.PARTICIPANTS: The study was carried out in Huazhong University of Science and Technology from June to September in 2003. Forty-five primary students of 8 to 12 years old, who were grade 3 to 5 in Wuhan city,were enrolled in this study, including 26 dyslexic children (dyslexia group)and 19 normal readers (control group). All the enrolled children were righthanded. Informed consents were obtained from all the participants and their parents (guardians) after explanation of aims and steps of this study.METHODS: The functional near-infrared imager (fNIRI) was applied to detect the changes of cerebral blood oxygenation in left prefrontal lobe of dyslexic children and normal children in the primary processing (viewing passively, reading aloud, producing an action word) and secondary processing of Chinese characters (outputting task, action words association) of Chinese characters.MAIN OUTCOME MEASURES: The changes of cerebral blood oxygenation in the primary processing and secondary processing of Chinese characters were observed in both groups.RESULTS: All the 26 children with Chinese dyslexia and 19 normal children were involved in the analysis of results. ① Changes of the contents of blood oxygenation in the primary processing of Chinese characters:When viewing the Chinese characters passively, the contents of blood oxygenation on channel A, B and C were all higher in the dyslexia group than in the control group (0.378 0, 0.134 6; 0.085 8, 0.051 9; 0.109 3, 0.069 2;P ＜ 0.05); there was no obvious difference on channel D between the two groups (P ＞ 0.05). When reading aloud, the contents of blood oxygenation on channel A, B, C and D were all unobviously higher in the dyslexia group than in the control group (P ＞ 0.05). In the process of generating action words, the contents of blood oxygenation on channels A and C were all higher in the dyslexia group than in the control group (0.411 2, 0.139 7;0.141 3, 0.078 4; P ＜ 0.05), and there were no obvious differences on channels B and D between the two groups (P ＞ 0.05). ② Changes of the contents of blood oxygenation in the secondary processing of Chinese characters: In the process of outputting task, the changes of blood oxygenation was lower in the dyslexia group than in the control group (-0.025 7, 0.089 0,F=16.25, P ＜ 0.01); In the process of action words association, the changes of blood oxygenation was obviously higher in the dyslexia group than in the control group (0.073 0, -0.072 1, F=15.59, P ＜ 0.01).CONCLUSION: The cortexes of left prefrontal lobe in dyslexic children are activated in the process of recognizing Chinese characters, but the degree and pattern of activation are different from those of normal children.The functional abnormalities of specific brain area may be the biological basis of Chinese dyslexia.Song RR, Wu HR.Changes of regional cerebral blood oxygenation in recognizing Chinese characters in children with Chinese dyslexia.

Objective To analyze the clinical characteristics and prognostic factors of endometrial carcinoma in senile women, explore the optimized therapeutic modality. Method The clinic pathological characteristics and survival outcome of 268 patients of endometrial carcinoma in senile women were reviewed retrospectively, and prognostic factors affected the survival of endometrial carcinoma were evaluated. Results According to univariate analysis, therapeutic modality, surgical-pathological classification and pathological grade were closely correlated with prognosis of endometrial carcinoma in senile women(P < 0.01 ). According to COX multivariate analysis,surgical-pathological and pathological grade were independent prognostic associated-factor (P = 0.002,0.000). Conclusions There are closely correlations between prognosis and surgical-pathological classification,therapeutic modality and pathological grade,surgical-pathological classification and pathological grade are independent prognostic associated-factor. The therapy on endometrial carcinoma in senile women should connect with high risk factors and adopt integrating and individual therapeutic modality.

Stasis is the critical causative factor and pathological production considered in clinic treatment. Promoting the circulation in blood vessel and removing stasis are equally important in treatment. Stasis is interactive with qi and blood. Removing stasis aims to regulating the circulation of qi and blood. Scraping therapy is one of the major approaches to stasis removal in TCM. In clinical practice, the stasis can be removed with scraping, bleeding and cupping, etc. Additionally, removing stasis with scraping should be combined with regulating qi and blood to enhance the therapeutic effect.
