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

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.

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.

Objective To compare biomechanical performances of parallel plate fixation and vertical plate fixation for better clinical treatment of humeral intercondylar comminuted fractures (HICF).Methods Models of T-shaped fracture were created using an osteotome at the distal end of humerus in 6 specimens of upper limb in 3 human adult cadavers.The 2 fracture models of left and right humeri in the same cadaver were respectively fixated with parallel plating and vertical plating.On a biomaterial-testing machine,a vertical load was applied onto the fixated distal humerus at a speed of 5 N/s till it reached 2000 N.The loading was repeated 3 times.Vertical compression displacement,intercondylar separating displacement,deformation of medial and lateral condyles and vertical compression stiffness were documented for statistic analyses. Results Under the same load,parallel plating led to significantly less compression displacement,separating displacement and deformation of condyles( P ＜ 0.05) but significantly greater axial compression stiffness( P ＜ 0.05) than vertical plating. Conclusion In biomechanics,parallel plate fixation has better performance than vertical plate fixation for HICF.

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 Toinvestigatetheeffectoffolicacidonplasmahomocysteine(Hcy)levels and vascular endothelial function in elderly cerebral infarction patients with hyperhomocysteinemia. Methods Thisstudywasaprospectivecontrolledtrial.Atotalof112elderlylacunarinfarction patients with high hyperhomocysteinemia admitted to the Department of Neurology,Nanjing Municipal Government Hospital from November 2012 to October 2013 were enrolled. The patients were divided into two groups according to the method of random number table. The patients of both groups received the conventional drug treatment of ischemic stroke at the same time. Fifty-six patients were in group A,and they were treated with folic acid 20 mg,once a day;56 patients were in group B,and they did not treat with folic acid. The Hcy levels on admission and after 24 weeks treatment were measured. Brachial artery flow-mediated endothelium-dependent dilation (FMD)was measured by high resolution ultrasound,and nitric oxide (NO), nitricoxidesynthase(NOS),andendothelin(ET)weredetectedatthesametime.Results Twenty-four weeks after treatment,the plasma Hcy level in group A was significantly decreased as compared with prior treatment (12. 2 ± 4. 2 vs. 22. 6 ± 3. 7μmol/L;P<0. 05),moreover,it was lower than the level of group B at the same period (12. 2 ± 4. 2 vs. 21. 8 ± 4. 0μmol/L;P <0. 05 ). The FMD level of group A was significantly higher than that of prior treatment and group B (11. 2 ± 3. 6 vs. 9. 2 ± 3. 3,9. 3 ± 3. 3;P<0. 05). The NO and NOS levels of group A at 24 weeks after treatment were significantly higher than those of prior treatment and group B at the same period (76. 2 ± 9. 4 vs. 49. 2 ± 9. 0,50. 0 ± 9. 1μmol/L,47. 6 ± 9. 5 vs.38. 4 ± 7. 5,37. 8 ± 8. 8 kU/L;P<0.05). The ET level of group A was decreased as compared with that of prior treatment and group B at the same period (81. 3 ± 20. 5 vs. 105. 6 ± 25. 2,105. 3 ± 21. 8 ng/L;P<0.05).NoadversereactionwasfoundduringthetreatmentingroupA.Conclusion Alargerdoseof folic acid can significantly reduce the plasma Hcy level,decrease the FMD level,and ameliorate vascular endothelial function in elderly cerebral infarction patients with hyperhomocysteinemia.

The financial compensation mechanism for public county hospitals are discussed and analyzed in the paper.Such a mechanism is analyzed by means of media coverage and literature consulting,along with field survey.Roadblocks have been found in implementation of the mechanism, namely delayed payment of capital expenditure compensation,poor support for medical equipment purchase,gaps in development key disciplines development,insufficient compensation for retirees expenses,poor definition of policy-incurred losses,and unclear compensation of public health services.in a word,it is imperative to change the unreasonable financial compensation mechanism,before the six financial compensation subsidies can be fully put in place and financial compensation made efficiently.

Objective To explore the clinical value of colposcopy directed biopsy in diagnosis of vaginal intraepitheal neoplasia (VaIN).Methods The clinical data of 106 VaIN patients diagnosed by colposcopy directed biopsy were reviewed and analyzed retrospectively.In the past medical history of 106 patients,46 patients had cervical cancer history,43 patients had cervical intraepithehal neoplasia history,13 patients had previous hysterectomy because of benign disease and 4 patients had uncertain past medical history.Results Among 106 patients,97 patients(91.51％,97/106) had abnormal pap smears of vagina,9 patients (8.49％,9/106) had abnormal pap smears of cervix.Histological analysis revealed that 69 patients were VaIN Ⅰ,24 patients were VaIN Ⅱ,13 patients were VaIN Ⅲ.The high-risk human papilloma virus (HPV) test at diagnosis were positive in 98 patients (92.45％,98/106),negative in 8 patients (7.55％,8/106).Eighty-seven patients VaIN were localized in the upper one third of the vagina,19 patients VaIN were localized in other parts of vaginal wall.Ninety-eight patients VaIN affected to the multifocal vaginal wall,8 patients VaIN affected to the focal vaginal wall.Conclusions It has highly therapeutic value of colposcopy directed biopsy in diagnosis of VaIN.But should closely correlated to past medical history,colposcopy should performed on the whole vagina wall and multiple punch biopsy to elevated positive rate.
