Objective To investigate the effects of pyrrolidine dithiocarbamate(PDTC) on aquaporin-9(AQP9) expression and brain edema around the hematoma in experimental intracerebral hemorrhage(ICH).Methods 128 SD rats were randomly divided into four groups: normal group,control group,ICH group and PDTC group.According to Rosenberg's methods,the models of experimental ICH were established.The rats in PDTC group were received PDTC intraperitoneally 2 h later.The brain weight column(BWC) at different time point was calculated by gray-wet method,and the expression of AQP9 was examined by immunohistochemistry.Results The BWC and expression of AQP9 in hematoma side of ICH begin to increase 4 h after ICH,peaked at 72 h,and decreased 120 h later.The BWC in opposite side of hematoma also increased 4 h after ICH and peaked at 72 h.Compared with control group,the BWC and expression of AQP9 in ICH group were higher,especially in hematoma side of brain(all(P

Seventeen physiological,biochemicaland morphological indexes consistently showed that Astragalus polysaccharide was able to enhance the myocardia contractility,attenuate the area of myocardial infarction, and reduce the degree of myocardial damage of myocardially infarcted dog heart in vivo.The mechanism might be related to the inhibition of Na+-Kr+ATPase activity & the anti-free-radical-damage action.

Babesia parasites are obligate intracellular apicomplexan protozoa and important pathogens causing babesiosis of humans and animals. They have conserved subcellular structures and invasion mechanism. Rhoptry⁃associated proteins，which are released into the host cell，are considered to be the key molecules of invasion and replication of parasites in the host cell and are immunosuppressive factors of the host cell mediated immunity in the stage of parasitophorous vacuole（PV）formation. The knowledge about rhoptry⁃associated proteins has made a great progress with the development of genomics and proteomics，so we review the research progress in rhoptry⁃associated proteins of different Babesia including Babesia bovis，B. ovine，B. gibsoni，B. bigemina and B. orientalis，etc.

Objective BOLD-fMRI was used to observe the activated auditory cortex evoked by pure tone stimuli in patients with sensorineural hearing loss and this paper is to discuss the objective measure for patient with sensorineural hearing toss. Methods BOLD-fMRI examinations were taken in 22 patients with unilateral moderate to severe sensorneural hearing loss and 15 control subjects. The volumes and intensities of the two hemispheres of the activated auditory cortex were analyzed quantitatively. Results Significant activation was found in the temporal lobe in control subjects, and significant differences in the volume and intensity were noted between the contralateral and ipsilateral activated auditory cortexes in them (P<0.01), exhibiting clearly eontralateral predominance. When the normal ear of patients with sensorineural hearing loss received signals, there was no significant difference be-tween contralateral and ipsilateral activated auditory cortexes (P>0.05). Conclusion When the normal ear of pa-tients with sensorneural hearing loss was stimulated by pure tone, the contralateral hemisphere predominance disap-peared. This result seems to show the plasticity of auditory cortex of patients with unilateral hearing loss.

Objective To explore the application value of dynamic vascular patterns(DVP) curve and parameter figure in the focal liver lesions by contrast-enhanced ultrasound(CEUS).Methods 83 cases of focal liver lesions diagnosed by pathologically or clinically that had undergone CEUS were analyzed by SonoLiver software.Then DVP parametric images were constructed and the time-intensity curve (TIC) parameters were calculated by TIC and DVP curve.Results Rise time(RT),time to peak(TTP),maximum intensity(IMAX),mean transit (mTT),slope of rise,and the absolute value for slope of half down between malignant and benign lesions groups indicated statistically significant difference (P ＜0.05).94.9％ of type Ⅰ was malignant lesions and 100％ Ⅳ type was benign lesions.The four types of DVP curve(Ⅰ,Ⅱ,Ⅲ,Ⅳ)in malignant and benign lesions were 72.5％,13.7％,13.7％,0 and 6.2％,43.8％,31.2％,18.8％,respectively.The proportion and characteristic of DVP parametric images and DVP curves in malignant and benign lesions groups were consistent.Conclusions DVP curve and parametric images of CEUS can demonstrate the difference of flow perfusion static between lesions area and surrounding liver parenchyma dynamically and directly.These are new qualitative indexes of the differential diagnosis in focal liver lesions.

Objective This paper aims to make clear the post-disaster medical needs of residents in the disaster areas and changes among the poor population, for the purpose of policy recommendations on post-disaster medical assistance. Methods Such methods as in-home questionnaire survey and literature study were used to study the income, prevalence rate and mental health of 4 380 households in 10 counties (cities and districts) in the disaster areas. Results In the hardest hit areas, 80. 4% and 52. 8% of residents in rural and urban areas are dependent on government relief respectively;the proportion of poor population resulting from the disaster rose from 5% before the disaster to over 75% afterwards in the hard-hit areas, while such a population rose to 15% in the hardest-hit areas and about 10% in general disaster areas;It is estimated that the new medical aid funds in Sichuan Province will reach 350 million yuan, two-fold that of the budget for 2009;In the hardest hit areas, the two-week prevalence rate per thousand people is twice that found in the third survey of health services in 2003, characterized of acute respiratory illness and rheumatoid;In the hardest-hit areas, nearly 70% of the residents are exposed to high mental health risks. Conclusion Recommendations: Strengthening the raising and use of medical aid fund;dynamic management for the population in need of post-disaster medical aid;Developing appropriate medical aid packages to fit post-disaster health needs and postdisaster disease characteristics;and consolidating the connection between medical aid and primary medical insurance system.

Objective To investigate the severity of cough in patients with different etiology of chronic cough and its related factors. Methods One hundred and fifty patients with chronic cough were recruited. The diagnosis of the patients was as follows: 24 cases with post nasal drip syndrome (PNDs), 26 cough variant asthma (CVA), 20 gastroesophageal reflux-induced cough (GERC), 31 eosinophilic bronchitis (EB), 30 atopic cough (AC) and 19 cough post infection (CPI). The severity of cough at daytime and night-time were scored by the doctor and the patient at the first visit. The correlation between cough score and age, gender and course duration of patients was analyzed. Results There was no significantly difference of cough score at daytime among different groups. Cough score at night in CVA group was significantly higher than that of other five groups (all P <0.01). Regression analysis showed that cough score at daytime was significantly correlated with age of patients (P < 0.05), while cough score at night was correlated significantly with gender (P < 0.01). Conclusion Cough severity at daytime in different etiology of chronic cough is similar, while that at night in patient with CVA is higher than that with other etiology.

Aim: To prepare novel aqueous polymer dispersions with high flexibility for sustained-release coating and investigate their properties. Methods: The aqueous polymer dispersions were synthesized by the emulsion polymerization. The physico-chemical properties and film-forming potential of the dispersions were investigated while the mechanical properties of the formed film and the drug release behavior when atenolol pellets were coated with the aqueous polymer dispersions were evaluated. Results: The prepared aqueous polymer dispersions (methyl methacrylate/ethyl acrylate, 1:2) were found to have proper physico-chemical properties, excellent film-forming capability and satisfying mechanical properties. It could form free film with high flexibility and low viscosity in low temperature even in absence of the plasticizer. Sustained release of atenolol pellets was achieved when the pellets were coated the polymer dispersions. 4-h and 8-h cumulative releases were more than 50% and 80%, respectively. There was no significant difference in release between pellets prior to and post compression of the coated pellets. Conclusion: The resulting aqueous polymer dispersions could be used as sustained-release coating material with high flexibility suitable for tableting.
