Powder X-ray diffraction (PXRD) technology combined with cluster analysis method was used to classify 75 batches of crystalline ceftriaxone sodium into subtypes, the crystalline characteristics of each subtype were measured with scanning electron microscope (SEM). By comparing some parameters of these subtypes correlated to crystallization process of ceftriaxone sodium, such as salification rate, water content in different subtypes, as well as by studying different lattice stabilities, different compatibilities with rubber closures during accelerated stability tests, the key point to improve the quality of domestic ceftriaxone sodium was disclosed. The results of this paper indicated that the fine structure of the products could be controlled well by improving the salification and crystallization process. As a result, the subtype II of ceftriaxone sodium with high stability can be produced.

Objective To study intermediate and long term efficacy of uterine arterial embolization (UAE)with sodium alginate microspheres(KMG)at diameters 500-700μm in treatment of diffuse adenomyosis.Methods Totally 40 patients with standard difluse adenomyosis were enrolled and treated with UAE.KMG at diameters 500-700 μm for vascular embolization were used to embolize the arteries.The degree of dysmenorrhea,amount of menorrhea and uterine volume,as well as the level of serum CA125,follicle stimulating hormone(FSH),luteinizing hormone(LH),estradiol(E2)were investigated before andafter UAE.Results The follow up rates were 100%(40/40),100%(40/40),80%(32/40),68%(27/40),58%(23/40)after uterine arterial UAE 12,24,36,48 and 60 months respectively.The early,intermediate and long-term effective rates were 90%(36/40),88%(28/32),83%(19/23).The degree of dysmenorrhea,the amount of menorrhea and the uterine volume,as well as serum CA125 all decreased significantly 3 mouths after UAE at varying degrees(P＜0.05).Compared with other follow-up time,thedegree of dysmenorrhea and the amount of menorrhea declined to their lowest point at 6 month after UAE (P＜0.01).Paralleled with the decrease of volume of uterine,serum CA125 also decreased significantly and reached the lowest level 12 months later compared with other follow-up times(P＜0.01).Even at the 12th month after UAE serum CA125was not normal and FSH,LH and E2 did not change all the times after UAE(P>0.05).No recurrence was found during the 60 months after UAE.Condusion KMG used in UAE at diameters 500-700 μm has good intermediate and long term effectiveness in treatment of diffuse adenomyosis with no side effects.

Objective To investigate the spatial organization of neurons, blood vessel and astrocytes at different time of reperfusion after focal cerebral ischemia in rats. Methods 24 Sprague-Dawley rats were randomly divided into sham group (n=8), reperfusion 1 day group and reperfusion 2 weeks group. The latter 2 groups were occluded the middle cerebral arteries for an hour and reperfused. All the rats were injected with gelatin ink. The expressions of glial fibrillary acid protein (GFAP) and neuronal nuclear antigen (NeuN) in the brain were observed with immunohistochemistry. Results The vessels located mainly in cortex and nucleus. Most of astrocytes apophysis connected with vessels and neurons. Compared to the sham group, the expression of GFAP increased significantly in ischemic side, and the expression of NeuN decreased 1 day and 2 weeks after ischemia-reperfusion. The vessels decreased in the ischemic side 1 day after cerebral ischemia-reperfusion, and then increased 2 weeks later. Conclusion The organization of neurovascular unit after cerebral ischemia-reperfusion has been observed.

Objective:To know the amount of literacy and scores of behavior problems of the grade 2-5 pupils in the primary school,and explore the correlation between them.Methods:A total of 673 pupils from grade 2 to 5 in primary school of Nanhai distric,Foshan City were enrolled.Their amount of literacy was assessed with the Primary School Literacy Assessment Scale,and their teachers were assessed with the Conners Teacher Rating Scale.Results:The amount of literacy in different grades,genders and parents' education levels were significantly different among the primary school students (P ＜0.05),girls's scores were higher than boys's [(2312 ±719) vs.(2184 ±734),P ＜ 0.05],students whose parents of high education level were higher than those of low education level (P ＜ 0.05).Scores of hyperactivity,inattentive-passive behaviors and conduct problems in different grades and genders were significantly different.Scores of Grade 2 pupils were higher than others,and boys's scores were higher than girls' s (P ＜ 0.05).Three factors of CTRS,including conduct problems (r =-0.31),hyperactivity (r =-0.43) and inattentive-passive behaviors (r =-0.36) and hyperactivity index(r =-0.38) had significantly negative correlation with the amount of literacy (P ＜ 0.001).Regression analysis showed that hyperactivity (β =-22.27,P ＜ 0.01) and conduct problems (β =-17.69,P ＜ 0.01) could significantly explain the amount of literacy (R2 =0.81).Conclusion:It suggests that hyperactivity and conduct problems are moderately associated with the amount of literacy in primary pupils.

Objective To analyze the electroencephalograph (EEG) features of 43 patients with clinically possible or probable Creutzfeldt-Jakob disease (CJD) and its correlation with megnetic resonance imaging (MRI) imaging and clinical manifestations.Methods All patients diagnosed with suspected CJD who were hospitalized in Xuanwu Hospital from January 2013 to December 2015 were collected.The clinical data, EEG and MRI imaging features were analyzed retrospectively.Based on the periodic sharp wave complexes (PSWC) appearance in EEG results, the patients were divided into typically changed group (TCG), atypically changed group (ACG) and unchanged group (UCG).Age, disease duration, clinical manifestations and MRI features among three groups were analyzed and the correlations between patient′s EEG features and age, disease duration, clinical manifestations or MRI features were explored using spearman method.Results Among the 43 patients with possible or probable CJD disease, 26 were male and 17 were female with an average disease duration of 4 months.The age of onset ranged from 31 to 80 with an average of (58.0±9.8) years old, and 86.0% of patients were 51 years old or above.Clinical characteristics of CJD patients according to occurrence rate were as follows: 35 cases (81.4%) with cognitive impairment, 29 cases (67.4%) with mental and behavior disorder, 28 cases (65.1%) with pyramidal tract damage, 24 cases (55.8%) with cerebellar symptoms, 23 cases (53.5%) with extrapyramidal symptoms,17 cases (39.5%) with myoclonic, 13 cases (30.2%) with dyssomnia, 13 cases (30.2%) with visual disorder and 2 cases (4.7%) with akinetic mutism.Regarding EEG features, 39.53% (17/43) of patients showed typical periodic sharp wave complexes (PSWC) (TCG group), 51.2% (22/43) had irregular rhythm and different forms of slow wave (ACG group) and only 9.3% (4/43) had no EEG change (UCG group).The occurrence rate of ribbon sign in MRI was 82.4% (14/17) in TCG group, 77.3% (17/22) in ACG group and none in UCG group.The rates were significantly higher in TCG and ACG group than that in UCG group (both P<0.05).Spearman correlation analysis revealed that EEG features was correlated with disease duration (r=0.351, P=0.021) and visual impairment (r=-0.377, P=0.013) for all CJD patients.There was no correlation between EEG and MRI or other clinical manifestations such as myoclonic, age and so on (all P>0.05).Conclusions EEG showed typical changes associated with disease duration in different stages of disease.EEG and MRI are two different means to evaluate different aspects of patients with CJD disease, and combination of two means could achieve better evaluation results.
