The purity of 4,4′-dimethoxy-5,6,5′,6′-bis (methylenedioxy)-2′-morpholine methylenebiphenyl-2-methyl formate methanesulfonate (IMH), a new drug for fatty liver treatment, was determined through differential scanning calorimetry (DSC). Analysis of two-factor non repeatability method was performed in the investigation the effects of two factors (heating rate and sample weight) on purity determination. The DSC experimental parameters were optimized as follows: heating rate was 10 ℃·min^-1, temperature range was 150-300 ℃, sample weight was 2.0-4.1 mg, and N₂ flow rate was 80 mL·min^-1. The linear correlation coefficient (r) of this DSC method was 0.999 8. The RSD value (n = 6) of precision was 0.03%. The standard value and uncertainty of the purity results of the multiple batches of IMH drugs were (99.74 ± 0.29)%, (99.91 ± 0.28)%, (99.90 ± 0.28)%, and (99.81 ± 0.28)% with inclusion factor (K) of 2 and confidence probability (P) of 0.95. The results were basically consistent with the results of the mass balance method. The DSC mehod is a simple, rapid and accurate method, and provides a new reference method for determining the purity of IMH drugs, improves the accuracy and reliability of purity determination.

Background There is multi-dimensional order of spatial stereopsis perception in human,however,current stereopsis examination is zero-order of position disparity.A multi-dimensional space perception model is very important for the detection of stereoacuity.Objective This study was to screen the deficit of zero-order,first-order,second-order multi-dimensional spatial stereopsis perception in amblyopia and strabismus children and to explore the association of zero-order,first-order,second-order spatial perception deficit.Methods Multidimensional spacial perception was examined in 79 children aged 4-14 years in Beijing Children' s Hospital.Nineteen normal children,19 children with ametropia amblyopia,12 children with anisometropic amblyopia,18 children with strabismus and 11 children with strabismus combined amblyopia were included this study.The random-dot and line spatial stereopsis perception in zero-order,first-order and second-order were examined with a new system of multidimensional space perception screening.Written informed consent was obtained from each subject or custodian before any ocular examination associated with this study.Results Absence of zero-order,first-order,second-order random-dot channel was found in 24 children (24/79,30.4％),18 children (18/79,22.8％) and 24 children (24/79,30.4％) respectively,with an average percentage of 27.9％.Absence of zero-order,first-order,second-order line channel was examined in 37 children (37/79,46.8％),37 children (37/79,46.8％),32 children (32/79,40.5％),with an average percentage of 44.7％.In the children with a deficiency of the zero-order spatial perception,the children who still remained the first-order or/and second-order spatial perception of random-dot accounted for 41.6％ and that of lines accounted for 43.2％.In children without deficiency of zero-order random-dot or lines spatial space perception,deficiency of first-order and/or second-order spatial perception was in 37.5％ children.Various order spatial perception deficiency was seen in children suffering from amblyopia or strabismus compared with normal group(P ＜ 0.05).Conclusions There exists spatial perception deficiency in children with amblyopia or strabismus.The patients with zero-order spatial perception absence partially remain a first-order or/and second-order spatial perception;while the patients with normal zero-order spatial perception might have first-order or second-order spatial perception deficiency.The multi-dimensional space perception model has a directive role for the training of visual information process and the treatment of spatial perceptual learning in children with amblyopia or strabismus.

OBJECTIVETo observe the changes in Aβ40, Aβ42 and ADDLs in brains of 3 month-old APPswe/PS1dE9 double transgenic mice after six-month intervention with curcumin, in order to discuss the neuroprotective effect of curcumin.

METHODAPPswe/PS1dE9dtg mice were randomly divided into the model group, the Rosiglitazone group (10 mg x kg(-1) x d(-1)) and curcumin high (400 mg x kg9-1) x d(-1)), medium (200 mg x kg(-1) x d(-1)) and low (100 mg x kg(-1) x d(-1)) dosage groups, with C57/BL6J mice of the same age and the same background in the normal control group. After 6 months, the immunohistochemical staining (IHC) and the Western blot method were used to observe the changes in positive cell of Aβ40, Aβ42 and ADDLs in hippocampal CA1 area, their distribution and protein expressions.

RESULTBoth of the immunohistochemical staining and the Western blot method showed more positive cell of Aβ40, Aβ42 and ADDLs in hippocampal CA1 area and higher protein expressions in the model group than the normal group (P < 0.01). IHC showed a lower result in the Rosiglitazone group than the model group (P < 0.05), while Western blot showed a much lower result (P < 0.01). The number of Aβ40, Aβ42 and ADDLs positive cells and the protein expressions decreased in the curcumin high group, the medium group showed a significant decrease (P < 0.01), and the low dose group also showed reductions in the protein expressions of Aβ40 and Aβ42.

CONCLUSIONThe six-month intervention with curcumin can significantly reduce the expressions of hippocampal Aβ40, Aβ42 and ADDLs in brains of APPswe/PS1dE9 double transgenic mice. Whether curcumin can impact Aβ cascade reaction by down-regulating expressions of Aβ40, Aβ42 and ADDLs and show the neuroprotective effect needs further studies.

Objective To explore the characteristics of dipyridamole 201 Tl myocardial perfusion imaging (MPI) SPECT in patients with dilated cardiomyopathy. Methods Thirty patients with dilated cardiomyopathy underwent pharmacological stress 201Tl MPI SPECT after intravenous infusion of dipyridamole (0. 56 mg/kg) for 4 min. The early and delayed SPECT images were acquired respectively at 10 and 240 min after 201Tl injection. The images were analyzed and reported by two or three experienced nuclear medicine physicians. Results All patients were found to have abnormal perfusion patterns at delay imaging, however 90.00% (27/30) were also abnormal at early images. Six patients had reverse redistribution. Conclusion Dipyridamole 201Tl MPI SPECT imaging may be of some value for the assessment of patients with dilated cardiomyopathy.

Several kinds of column chromatography method were used to investigate the chemical constituents of the leaves of Lophatherum gracile. The structures of the isolated compounds were identified based on their physicochemical properties and spectral data. A new flavone C-glycoside was isolated and its structure was identified as 3'-methoxyl-luteolin 6-C-beta-D-galactopyranosiduronic acid (1 --> 2) -alpha-L-arabinopyranoside (1).
