Objective To explore visual-spatial working memory deficits of patients with basal ganglia damage, based on which tried to provide the new method for detecting the injuries in basal ganglia. Methods Twenty-five patients with lesions in the basal ganglia and twenty-five healthy controls performed visual-spatial working memory tasks, including a face-recognition and a spatial delayed-response. Results For the basal ganglia damage group ,the correct rate of both visual- face ( 54.5 ± 9.6 ) % and visual-spatial ( 80.0 ± 11.7 ) % working memory tasks was significantly lower than that of the control group ( ( 64.3 ± 9.5 ) %, ( 93.6 ± 4.9) %, respectively) ,and the difference was statistically significant ( u= - 147.5,80.5, P＜0. 01 ). For the patients injured in the left basal ganglia, the correct rate of visual- face working memory (48.5 ± 5.4 )% was obviously lower than that of patients injured in the right basal ganglia ( 59.2 ± 9.8 ) %, and the difference was statistically significant ( u =25.5, P＜0. 01 ) ;but the difference of correct rate for the visual-space working memory was not statistically significant( u = 52.5, P＞ 0.05 ). In contrast to the controls, both the visual-face and visual-space working memory of the group with injuries in basal ganglia,had appeared to be disable. Conclusions The results confirmed that patients with lesions in basal ganglia had deficits of visual-spatial working memory,and that injuries either in the left or the right basal ganglia can probably cause the shiftiness of cognitive function. Therefore, the injuries in basal ganglia can be detected by the visual-spatial working memory tests.

Objective:The paper aims to evaluate the impacts of the urban residents’ basic medical insurance on the medical treatment and preventive care services utilization through quantitative evaluation. Methods:The China Health and Nutrition Surveys ( CHNS) Data collected from 2006 to 2011 were used to compare the difference between medical treatment and preventive care services utilization adopting the difference-in-difference method and the Probit model. The control group urban residents did not participate in the basic medical insurance while their treatment group participated. Results:The medical treatment and preventive care services utilization were more for the treat-ment group than they were for the control one. The age, education level, annual per capita income and hypertension influenced the medical services utilization, and the annual per capita income was a protective factor. The age and ed-ucation level also influenced the preventive care services utilization. Conclusion: The urban resident basic medical insurance plays an important role in the medical treatment and preventive care services utilization. Meanwhile, this factor continuously enhanced the coverage and the per capita income protection for medical services.

Objective: To research the clinical curative effect and explore the mechanism of penetrating of scalp-point on acute hypertensive intracerebral hemorrhage (ICH). Methods: 66 patients were randomly divided into two groups: one is the scalp-point therapeutic group, the other is the western medicine group. The two groups were all treated by dehydration, etc. In addition, there are 20 normal people to be set as the healthy group. To select the nervous functional deficit mark, activity of daily living (ADL) form, the amount S-100B protein as indexes and analysis the results. Results: the recordings indicate the patients' Serum S-100B protein are related with nervous functional deficiency mark. After 28 days, the recovery of patients' nervous function of scalp acupuncture group was obviously superior to that of control group (P＜0.05). Conclusions: The results suggested that the patients' Serum S-100B had positive correlation with nervous functional deficit; The penetrating of scalp-point had the better regulatory effect on the level of Serum S-100B, and could improve the nervous functional deficit and ADL, so as to improve the coordination and compensation function and the general nervous function between cortical functional areas

Objective To investigate the influence of ursolic acid on vascular endothelial growth factor ( VEGF) , cycloxygen-ase-2 (COX-2), and matrix metalloproteinases-2 (MMP-2) expressed in the mouse retinal ischemic model , and to explore the mecha-nisms of anti-angiogenesis.Methods Sixty 7-day clean-class C57BL/6J mice were divided randomly into 6 groups [ n =10 mice (20 eyes) per group]:blank control, model control (PBS), positive control (triamcinolone), and ursolic acid (UA) intervention (low-dose, medium-dose, and high-dose).Mice in the blank control group were raised in air , and mice in other groups in(75%±2%)O2 high-oxygen environment for 5 consecutive days .Mice in the model control group and breastfeeding mice were put back in air environ-ment (21%O2 ) on the 12th day after the new-born mice to induce the generation of retinal neovascularization .When models were suc-cessful, the drug treatments were applied immediately to the corresponding groups , with injection of 3μl of sterile PBS in model control group, 3 μl of 1.5, 3.00 and 6.0 μg UA in UA intervention group, and 3 μl of triamcinolone (1 ml∶40 mg) in positive control group, respectively.All mice were killed after overdose anesthesia on the 17th day.Their eyeballs were made into samples and retinal tissue pathological sections with H-E dying method.The positive expressions of VEGF , COX-2, and MMP-2 were detected with immu-nohistochemical method .The fresh retinal tissue homogenate was prepared to detect the protein expressions of VEGF , COX-2, and MMP-2 in retinal tissue with western blot method ,and mRNA expressions of VEGF , COX-2, and MMP-2 were detected with real-time fluorescent quantitative polymerase chain reaction ( RT-PCR) .Results According to protein and mRNA expressions of VEGF , COX-2,and MMP-2 in retinal tissue among six groups , protein expressions of VEGF , COX-2, and MMP-2 in model group were significantly higher than those in blank group ( P <0.05 ) .Each protein expression in the high UA intervention group was significantly lower than that in the model group ( P <0.05 ) .Each protein expression in the high UA intervention group was not significantly different from that in the positive group ( P >0.05 ) .Each protein expression in the high UA intervention group was significantly lower than that in the low UA intervention group( P <0.05).Conclusions UA inhibited expressions of VEGF, COX-2, and MMP-2 in retinal ischemia model .UA also played an inhibitory role in the formation of neovascularization , and this role was positively correlated with UA dose .

Objective: Surfactant protein A (SP-A) is protein that appears to play an important role in mammalian first-line host defense. The objective of this study was to immunolocalize SP-A in human sinonasal tissue. Method:Eleven cases of allergic rhinitis, fifteen cases of polyp and seven cases of normal middle turbinate were studied with immunohistochemistry and immunofluorescence method to detect the expression of SP-A. Result:The expression of SP-A in allergic rhinitis and polyp were dramatically higher than that in controls(P<0.05), and there was no remarkable difference in the expression of SP-A between allergic rhinitis and polyp(P>0.05). The result demonstrated that SP-A was positivly correlated with eosinophils within the basement membrane of epitheli-um(R=0.81,0.55). In the result of immunofluorescence, there was significantly higher expression SP-A in nasal mucosa of allergic rhinitis and nasal polyp than that in control group(P<0.05). Conclusion:SP-A is likely to play key roles in the inflammatory reaction process of allergic rhinitis and polyp. Its secretion in the upper airway indicates that future studies may allow manipulation of this protein and development of novel treatments for sinonasal pathology.

Objective:To explore the relation between parental cohesion,peer acceptance and the loneliness of left-behind children,and furthermore explore the mediation role of self-esteem.Methods:Totally 427 left-behind children in Hubei Province (275 males,152 females) were surveyed,and the Parental Cohesion Scale (PCS),Peer Nomination (PN),Self-Esteem Scale (SES) and Children Loneliness Scale (CLS) were used to assess parental cohesion,peer acceptance,self-esteem and loneliness respectively.The relation between parental cohesion,peer acceptance andthe loneliness of left-behind children,and the mediation role of self-esteem wereanalyzed.Results:The CLS scores in left-behind children were negatively correlated with the scores of PCS,PN,and SES (r =-0.31,-0.37,-0.50,P ＜ 0.01),the SES scoresplayed a mediation role in the relation between PN scores and CLS scores (95 ％ CI:-7.02--0.01),and between PCS scores and CLS scores (95 ％ CI:-0.18--0.09).Furthermore,the unique effect of the PN scores on the CLS scores (sr2 =0.10) was higher than that of PCS scores (sr2 =0.06).Conclusion:The current research indicates that the loneliness,parental cohesion,peer acceptance and self-esteem of the left behind children have a close relationship.Furthermore,it suggests that self-esteem may play partial mediating effects between parental cohesion,peer acceptance and the loneliness of left-behind children.

OBJECTIVE To study the significance by analyzing the expression of human protection of telomeres1(POT1)and telomeric repeatbinding factor-2(TRF2)in the tissues of laryngneal squamous cell carcinoma(LSCC)and in polyp of vocal cord tissues. METHODS The expression of POT1 and TRF2 in 20 tumor samples and 19 polyp of vocal cord were determined by the indirect immunofluorescence method. The results were scored and analyzed statistically. RESULTS The positive expression rates of POT1 and TRF2 in tumor samples was 65.00% and 70.00% respectively. There were no positive expression of POT1 and TRF2 in polyp of vocal cord. The positive expression of POT1 was higher in poorly differentiated laryngeal carcinoma than that in well-differentiated and moderately differentiated laryngeal carcinoma(Chi-square test with contingency table, P0.05). CONCLUSION The expression of POT1 and TRF2 in laryngneal squamous cell carcinoma were remarkable, POT1 and TRF2 may play a critical role in tumorigenesis of laryngneal squamous cell carcinoma. There was statistical significant difference for degrees of POT1 expression in different tumor histological grades.

Their structures have elucidated by TLC comparision with standard and spectral methods as ergosterol (Ⅰ), ergosterol peroxide (Ⅱ) cinnamic acid (Ⅲ), para-hydroxyphenylpropionic acid (Ⅳ) and beauvericin (Ⅴ), respectively.

We pretreated sawdust (Castanopsis fissa Rehd.et Wils) by solid state fermentation (SSF) with Phanerochaete chrysosporium, and then compressed it into pellets with the moisture content of 15% and the pressure of 98 MPa, to solve the problem of low density, low Meyer hardness, high water uptake, and short storage period of pellet in the woody pellet industry. We studied the effects of fermentation time on pelletization and pellets's characteristics (including energy consumption, density, Meyer hardness, and hydrophobicity). SSF affected the heating values of pellet. Compared with fresh sawdust, SSF consumed more energy at the maximal value by 6.98% but saved extrusion energy by 32.19% at the maximum. Meanwhile, SSF could improve the density, Meyer hardness and hydrophobicity of pellet. Pellet made of sawdust pretreated by SSF for 48 d had best quality, beneficial for long-term transportation and storage of pellets.
