Objective To analyze the differential expression of protein in taxol-resistance from elderly females with ovarian cancer, by compared proteomics analysis and identified the candidated marker in the clinical tissues. Methods Soluble fraction proteins in two SKOV3 taxol-resistant cells, SK-TR30 and SK-TR2500 and one A2780 taxol-resistant cell, A2780-TR paired taxol-sensitive ovarian cancer cells were separated and prepared by two dimensional gel electrophoresis (2-DE). The differentially expressed proteins were selected and identified by matrix-assisted laser desorption/lonization time of flight mass spectrometry(MALDI-TOF-MS) and database search. 2-DE profiles with high resolution and reproducibility were obtained. Then highly expressed protein-cofilin1 which exist in two forms of de-phosphorylate was detected and compared between human ovarian cancer specimens including 22 elderly female with chemosensitive and 21 elderly female with chemoresistant by immunohistochemistry. Results Among the identified proteins, there were sixteen over/under-expressed proteins in taxol-resistant cell lines as compared with taxol-sensitive cell lines. In particular, overexpression of cofilin1 and destrin were displayed in all three taxol-resistant cell lines. The expression of phosphorylation of cofilin (P<0.05), but not cofilin1, displayed much higher in chemoresistant than in chemosensitive group. Conclusions Cofilin1 may play a role of taxol resistance by phosphorylation of ovarian cancer cell. However, the mechanisms need to be elucidated further.

To rapidly identify the compound Yiganling tablets from different manufacturers by near-infrared fibre-opti-cal spectroscopy and detect the content of silymarin. Methods:The ninety-three batches of compound Yiganling tablets from six manu-facturers were used as the analysis objects. Clustering analysis model of compound Yiganling tablets was established. The spectra were pretreated with the second derivative and vector normalization;the number of smoothing point was thirteen; the wavelength range was 9 000-4 100 cm-1;the distance between the spectra was Euclidean distance, the distance between the spectra and the class was the sum of square of the variance(Ward’s method). The quantitative model was established using the same samples. The spectra were pretreated with the first Derivative and vector normalization;the number of smoothing point was seventeen;the wavelength ranges were 9 100-7 300 cm-1 and 7 100-4 100 cm-1;the regression method was partial least squares ( PLS) algorithm. Results:The clustering model could identify the samples of training set, and validate the thirty spectra of test set accurately. For the quantitative model of the content of silymarin, the root mean square error of cross validation (RMSECV) was 0. 082 8 and the determination coefficient R2 was 97. 98%. The root mean square error of prediction (RMSEP) was 0. 044 1 and the correlation coefficient R2 was 98. 95%. Conclu-sion:The clustering analysis and the quantitative model are rapid and simple, accurate and reliable, and can be applied in fast drug a-nalysis.

Objective To observe the intervention effect of BrainHQ visual training on depressive symptom in patients with post stroke depression.Methods Eighty patients with post stroke depression were divided into control group(n=40)and intervention group(n=40).The control group accepted routine drug therapy and conventional rehabilitation, while intervention group received BrainHQ visual training additionally.They were assessed with Hamilton depression scale(HAMD) before and 4 weeks after intervention.Results Before intervention the HAMD score between control group and intervention group(respectively(19.80±3.96), (18.43±2.94)) had no statistical difference (P>0.05).After 4-week intervention, the HAMD score of intervention group(9.58±5.42) was significantly lower than that of control group (13.85±5.73)(P<0.01).Before the intervention, depression level of two groups had no difference(P>0.05).After 4-week intervention,the difference of depression level was statistically significant in two groups(P<0.05).Conclusion BrainHQ visual training can improve depressive symptom in patients with post stroke depression.

Objective In order to observe the role of genetically modified Schwann cell (SC) with pSVPoMcat in the regeneration of injured spinal cord.Method The cells were implanted into the spinal cord.Ninety SD rats were used to establish a model of hemi- transection of spinal cord at the level of T8,and were divided into three groups,randomly, that is,pSVPoMcat modified SC implantation(Group A), SC implantation(Group B),and without cell implantation as control(Group C).After three months the presence of axonal regeneration of the injured spinal cord was examined by means of horseradish peroxidase(HRP)retrograde labeling technique and stereography.Result The results indicated that HRP labeled cells in Group A and B could be found in the superior region of injured spinal cord and the brain stem such as the red nuclei and oculomotor nuclei. The density of ventral horn neurons of the spinal cord and the number of myelinated axons in 100 μ m of the white matter was A >B >C group.Conclusion In brief,the pSVPoMcat modified SC intraspinal implantation could promote regeneration of the injured spinal cord.

Objective To systematically evaluate the association between IL-6 gene rs1800796 polymorphism and febrile seizures(FS)susceptibility.Methods The related literatures on IL-6 gene rs1800796 polymorphism and febrile seizures(FS)susceptibility were retrieved from PubMed,Web of Science Embase,Cochrane Library,CNKI,WanFang,VIP and CBM Databases by computer.OR and its 95%CI were taken as the pooled effects.The RevMan 5.2 software was adopted to conduct the statistical analysis.The publication bias analysis was performed by using the STATA12.0 software.Results Seven independent case-control studies were included according to the inclusion and exclusion standard,involving 516 accumulated cases and 528 controls.The results showed that IL-6 gene rs1800796 polymorphism had a significant association with FS susceptibility in Chinese population(GG+CG vs.CC:OR=2.22,P=0.05;G vs.C:OR=2.44,P<0.01;GG vs.CC:OR=3.69,P=0.03;GG vs.CG+CC:OR=3.43,P<0.01).The subgroup analysis was conducted according to possible important confounding factors,and the results showed that this gene polymorphism had a significant association with FS susceptibility in Chinese population(GG+CG vs.CC:OR=3.32,P<0.01;G vs.C:OR=3.23,P<0.01;GG vs.CC:OR=7.27,P<0.01;GG vs.CG+CC:OR=5.17,P<0.01:CG vs.CC:OR=2.56,P=0.02).But in other populations,except recessive model(GG vs.CG+CC:OR=2.40,P<0.01),all other genetic models did not display obvious correlation.The subgroup analysis was conducted by FS diagnostic standard,and the results showed that this gene polymorphism had a significant correlation with infantile FS onset in diagnosing FS by the Chinese standard(GG+CG vs.CC:OR=4.57,P<0.01;G vs.C:OR=4.36,P<0.01;GG vs.CC:OR=12.75,P<0.01;GG vs.CG+CC:OR=8.60,P<0.01:CG vs.CC:OR=3.40,P<0.01).Conclusion IL-6 gene rs1800796 polymorphism may be associated with infantile FS susceptibility and allele G may be a risk factor for FS onset.

Objective To illustrate and discuss the technique and clinical value of scapula Y-position radiography.Methods Scapula Y-position radiographies were performed on 110 patients with shoulder joint injury or omalgia.The patient standed in front of the panel face to face, with the affected joint closed to the panel, and the arms fell naturally and palms pronated to stick close to the body.The angle between the coronal plane and the panel was about 55 to 65 degree, put the affected caput humeri at the center of the panel,tilted the tube to foot-side by 15 degree,and aimed the axis at caput humeri.Results Among the 110 patients, 82 radiographies were successfully taken by the first time,28 failed because of the inappropriate body-tilt angle.We had exposed 5 acromion fractures cases, 20 flexural and hook-form acromion cases, 35 cases with the acomion-caput humeri distance less than 1 cm, and 2 coracoid fracture cases.Conclusion Scapula Y-position radiography has high clinical value that could expose the osseous anatomic exit of the rotator cuff and guide the clinical treatments.
