Objective To explore the relationship between apathy and lesion location and serum homocysteine during the acute stage of ischemic stroke. Methods 152 patients with acute cerebral infarction were recruited. 152 volunteers from medical center were as control group. The Apathy Scale (AS) was used to assess poststroke apathy (PSA). National Institutes of Health Stroke Scale (NIHSS) was used to assess the severity of stroke. Magnetic resonance imaging (MRI) with diffusion-weighted imaging (DWI) was used to evaluate the lesion location. Modified Fazekas Scale was used to assess leukoaraiosis. The serum levels of homocysteine of patients were determined. Results The prevalence of PSA was significantly higher in the patients than in the control group (P<0.001). Multivariate logistic regression demonstrated that frontal lesion (P=0.001), basal ganglia lesion (P=0.006), pons lesion (P=0.002) and higher homocysteine level (P<0.001) significantly related with PSA. Conclusion Frontal lesion, basal ganglia lesion, pons lesion and higher homocysteine level may be predictors for apathy in acute stage of ischemic stroke.

Objective To investigate the relationship of serum levels of macrophage migration inhibitory factor (MIF), matrix metallo-proteinase-9 (MMP-9), hypersensitive C-reactive protein (hs-CRP) with the severity of acute cerebral infarction (ACI). Methods 101 pa-tients with ACI were envolved and divided into 3 groups according to the scores of National Institute of Health Stroke Scale (NIHSS):mild group (group A, n=38, NIHSS score<4), moderate group (group B, n=36, NIHSS score 4-15) and severe group (group C, n=27, NIHSS score>15). Meanwhile, 44 non-ACI inpatients with atherosclerosis were included as control group (group D). Their serum MIF and MMP-9 were detected with ELISA, and hs-CRP with immunoturbidimety. Results The levels of serum MIF, MMP-9 and hs-CRP ranged from more to less as groups C, B, A and D (P<0.05). There was positive correlation of MIF with MMP-9 (r=0.301, P<0.01) and hs-CRP (r=0.309, P<0.001). Conclusion Serum MIF, MMP-9 and hs-CRP levels increased with the severity in ACI patients, which may be prediction of athero-sclerotic plaque instability.

Laser-induced breakdown spectroscopy ( LIBS) was used to detect the compositions of soil in the air, and the quantitative analysis model with genetic algorithm-partial least squares ( GA-PLS ) was established. A total of fifty-eight soil samples were split into calibration, monitoring and prediction sets. Eleven soil compositions including Mn, Cr, Cu, Pb, Ba, Al2 O3 , CaO, Fe2 O3 , MgO, Na2 O, and K2 O were quantitatively analyzed. The results demonstrated that, as a pretreatment method for optimizing the selection of spectral lines, GA could be effectively used to reduce the number of spectral lines for use in building PLS model, and hence simplify the quantitative analysis model. More importantly, for most of the soil compositions, GA-PLS could significantly improve the prediction ability compared with the conventional PLS model. Take Mn as an example, the root-mean-square error of prediction ( RMSEP ) was decreased from 0. 0215% to 0 . 0167%, and the mean percent prediction error ( MPE ) was decreased from 8 . 10% to 5 . 20%. The research provides an approach for further improving the accuracy of LIBS quantitative analysis in soil.

OBJECTIVETo observe the effect of Shenshuai Yingyang Capsule (SSYYJN) in ameliorating muscle atrophy in rats with chronic renal failure (CRF) and explore the role of Wnt7a-Akt/mTOR signal pathway in mediating this effect.
METHODSMale rats were randomly assigned to 5/6 nephrectomy group and sham-operated group, and the former group was further randomly divided into CRF model group, KA group, and SSYYJN group. The size of anterior tibia muscle was examined microscopically with HE staining. Protein synthesis in the soleus muscle was investigated by (14)C-phenylalanine experiment, and the expression of Wnt7a, frizzled-7, phospho-Akt, phospho-mTOR and GAPDH were detected with Western blotting.
RESULTSThe body weight, the wet and dry weight, cross-sectional area, and muscle protein synthesis of the anterior tibia muscles, and expressions of the proteins in the Wnt7a/Akt signaling pathway all increased significantly in SSYYJN and KA groups as compared with those in the model group.
CONCLUSIONSSYYJN can effectively improve muscle atrophy in the rat model of CRF possibly by reversing the reduction in the expressions of Wnt7a/Akt signaling pathway proteins in the skeletal muscles.
