Obtained by detecting the X-ray dose, pixel, the thickness of the above parameters are affected, but also the interaction between the above parameters simultaneously.Conclusion: By detecting the spatial resolution, low contrast resolution of medical image, we can effectively guarantee system performance, maintaining optimal image quality.

Objective: To design a heart rate testing procedure which based on Labview. Methods:Collect the blood oxygen signals of the fingers, which keep in step with the pulse wave. Filter the signals and obtain the pregnant datum by the Labview procedures. Results: Achieve the pulse cycle“T”by Labview processing the blood oxygen signals of the fingers, and gain the heart rate by calculating the pulse in one minute(Pulse is equal to the number of heart beat in one minutes-1/T,the heart rate). Conclusion:It is an important and meaningful work to process the signals. Not only acquire the heart rate, but also prompt and diagnose the diseases of the cardiovascular system. It also can provide some meaningful diagnostic evidence.

Objective To investigate the therapeutic effects of Yangxin Ningshen capsule in the treatment of insomnia. Methods 78 patients were randomly recurited into a control group (36 cases) and a treatment group (42 cases). The treatment group was administered with 1.6g to 2.0g Yangxin Ningshen capsule, three times daily, for 28 days. The control group was administered with Valium and Orgzanol tablets for 28 days. After 4 weeks therapy, the clinical effect was evaluated. Results The total effective rate and cure rate was 92.85% and 47.62% respectively in the treatment group. The total of effective rate and cure rate was 83.33% and 30.56% respectively in the control group, There was statistical difference between the two groups (P<0.05) .Conclusion The therapy of Yangxin Ningshen capsule has good effects in treating insomnia.

Objective To study the efficacy of Ciwujia injection combined with electric acupuncture in the treatment of arteria vetaebralis vertigo.Methods 66 cases with arteria vertebralis vertigo were randomly recruited into a control group with 30 cases and a treatment group with 36 cases.The treatment group was administered with Ciwujia injection and electric acupuncture for 10 days,and the control group was administered with flunarizine and Danshen injection for 10 days.Resuits After 10 days'therapy,thetotal effective rate and the cure ratewas 91.7%and 30.6%in the treatment group,and the total effective rate and the cure rate was 63.3%and 16.7%in the control group.There was statistical diflerence between the two groups(P＜0.05).Conclusion The therapy of Ciwujia injection and electric acupuncture has good effect in treating arteria vertebralis vertigo.

Objective To evaluate the efficacy and safety of transurethral plasmakinetic resection of the prostate(PKRP).Methods A total of 56 patients with symptomatic benign prostatic hyperplasia(BPH) underwent the PKRP.The weight of the prostate ranged 36~110 g(mean,50.3?26.4 g).All the patients were followed for 1~6 months postoperatively.Results The duration of the procedure was 25~100 min(mean,56?26 min),the weight of resected prostate was 10~89 g(mean,50?22 g),and the intraoperative blood loss,35~200 ml(mean,75?49 ml).No transurethral resection syndrome occurred.On 1,3,and 6 postoperative months of follow-up,the peak flow rate(Qmax) increased from 6.7?2.9 ml/s preoperatively to 17.4?5.1 ml/s,20.8?3.9 ml/s,and 21.6?4.6 ml/s,respectively,the international prostate symptom score(IPSS) decreased from 23.2?3.8 preoperatively to 6.9?1.7,6.1?2.1,and 5.9?1.5,respectively,and the quality of life(QOL) decreased from 5.7?1.5 preoperatively to 2.7?0.7,2.4?0.5,and 1.9?0.9,respectively.The differences between pre-and post-operative periods in the three indicators were all statistically significant(P

Objective:To discuss the effect of the choice of brain functional MRI parameter on image quality. Methods:To select nine young volunteers for scanning brain functional MRI from February to December, 2012, and analyze the effect caused by parameters to the image quality. Results:The lower of the b value, the more level 1 image, the less level 3 image;the more of the number of diffusion sensitive gradient direction, the more level 1 image, the less level 3 image. The largest impact on image quality is the interlayer spacing, the number of diffusion sensitive gradient direction and the b value. Conclusion:The factors influencing the quality of brain functional MRI images including the interlayer spacing, the number of diffusion sensitive gradient direction and b value. In the parameter selection process, one should start from diagnostic purposes and weigh the pros and cons with overall consideration.

Objective In order to find the pollution source and provide some useful references for the controlling of the heavy metal pollution to the tea. Methods From March to April,2007,the soil and tea samples were collected from 10 tea gardens in the main producing areas. The soil samples were digested.
