ObjectiveTo observe the clinical efficacy of acupuncture plus neuromuscular electrical stimulation in treating motor aphasia after ischemic stroke.MethodSeventy-five patients were randomized into a control group of 38 cases and a treatment group of 37 cases. The two groups both received basic treatment. Besides, the control group was given acupuncture treatment; the treatment group was given acupuncture plus neuromuscular electrical stimulation. The acupuncture treatment and neuromuscular electrical stimulation were given once a day, 10 d as a treatment course, totally for 2 successive courses. The Aphasia Battery of Chinese (ABC) was observed before and after treatment to evaluate the speech function.ResultThe total effective rate was 81.6%in the control group versus 89.2% in the treatment group, and the difference was statistically significant (P<0.05). The Communication Activities of Daily Living (CADL-T) scores were significantly increased after intervention in both groups (P<0.01), and the CADL-T score of the treatment group was significantly higherthan that of the control group (P<0.01).Conclusion Acupuncture is effective in improving the speech dysfunction and the quality of life in patients after ischemic stroke, and it can produce a higher therapeutic efficacy when combined with neuromuscularelectrical stimulation.

Registration of serial images plays an increasingly important role in medicine. A novel registration method used for serial images matching is proposed, which is based on the joint histogram. After thresholding the two images to be registered, the joint histogram is divided into four separate regions. Then the criterion function is defined as bin counting in a specific region of the joint histogram, which simplifies the computation of the criteria function greatly and speeds up the alignment process significantly. We choose the Powell optimization algorithm to calculate the registration parameters. The comparison of the results from both mutual information and our method shows that the new method based on segmentation and counting is a fast, simple, efficient and accurate registration method.

Objective To understand the relationship between Toxoplasma gondii infection and pet-breeding and hygienic status. Methods One or two districts were chosen from Jining City, Za-ozhuang City and Linyi City as study areas and the questionnaire surveys were carried out for hygienic status, etc. The pet-breeders and non-pet-breeders were paired by sex, age, living place and occupation so on in a ratio of one to one. Blood samples taken from each were tested for antibodies against T. gondii with ELISA in a double-blind method. Results The total infection rate was 14. 25%, much higher than that investigated ten years ago (1. 53%). The mean positive infection rate was 19.91% in the pet-breeding groups and 8.60% in the control groups (x2 = 11.57, P

Objective To investigate the performances and characteristics of femoro-acetabular impingement (FAI)on MSCT. Methods Hips jointed MSCT scans of 109 cases (as case group)and the other 120 cases (as control group)were analyzed retrospec-tively,to analyze the anatomy and osseous abnomality of FAI.Alpha angle,offset,CE angle were measured.The data were tested by using t test and ANOVA test.Results There were 57 cases of osseous protuberance at the femoral head and neck joint,26 cases of the offset reduction,17 cases of over-coverage acetabulum,41 cases of over-deep acetabulum,20 cases of acetabular retroversion,57 cases of subcortical cystic degeneration at the femoral head and neck joint and 22 cases of subchondral cystic degeneration at the ace-tabulum margin.Significant statistical differences were found between case group and control group in alpha angle value,offset and CE angle (P<0.05).Multiple comparisons demonstrated that except results between the value of alpha angle of Cam-type and Mixed-type(P=0.071),Pincer-type and the control group(P=0.083)with no statistical significance,the differences between any other two groups reached statistical significance (P<0.05).Multiple comparisons demonstrated that except result between the value of offset of Cam-type and Mixed-type(P=0.561)with no statistical significance,the differences between any other two groups reached statistical significance (P<0.05).Multiple comparisons demonstrate that except results between the value of CE angle Pin-cer-type and Mixed-type (P=0.444),Cam-type and the control group (P=0.236)with no statistical significance,the differences be-tween any other two groups reached statistical significance (P<0.05).Conclusion Different type of FAI has its unique anatomical features.Alpha angle,offsetand CE angle for the diagnosis of FAI have important reference values.
