Comparation of effect and cost-benefit analysis between acupoint catgut-embedding and electroacupuncture on simple obesity / 中国针灸

<p><b>OBJECTIVE</b>To compare the clinical effect of acupoint catgut-embedding and electroacupuncture on simple obesity and evaluate the economics benefit by cost-benefit analysis.</p><p><b>METHODS</b>Sixty cases were randomly devided into an acupoint catgut-embedding group and an electroacupuncture group, 30 cases in each group. Zhongwan (CV 12), Tianshu (ST 25), Daheng (SP 15), Shuifen (CV 9), Qihai (CV 6), Guanyuan (CV 4), Zusanli (ST 36) and Ashi acupoints were selected as the main acupoints in both groups. The acupoint catgut-embedding group was treated with acupoint catgut-embedding, once each week, four weeks as a course for two courses. The electroacupuncture group was treated with electroacupuncture, three times each week for eight weeks.</p><p><b>RESULTS</b>1) The total effective rate in the acupoint catgut-embedding group was 90.0% (27/30) and in the electroacupuncture group was 86.7% (26/30), with the similar therapeutic effect between the two groups (P > 0.05). 2) The body mass, body mass index (BMI), waistline, hip circumference and waist-to-hip ratio in the two groups were all decreased significantly (all P < 0.05). 3) The total medical treatment cost in the acupoint catgut-embedding group was 61 500 yuan and the cost per patient was 2050 yuan, and in the electroacupuncture group, the total cost was 117 210 yuan and the cost per patient was 3907 yuan. The cost effect analysis showed that there were 1857 yuan of the cost per patient in the acupoint catgut-embedding group less than that in the electroacupuncture group.</p><p><b>CONCLUSION</b>Acupoint catgut-embedding has significant effect in treating simple obesity with low cost and fine economics benefit.</p>

Algorithm of digital demodulation and filtering in MRI spectrometers / 中国医疗器械杂志

In the design of RF receiver of the digital MRI spectrometer console, a digital demodulation and filtering algorithm is presented in this thesis. The MR signals are firstly converted to digital signals by the A/D converter, and then quadrature-demodulated from high frequency carrier wave. The CIC filter, half-band filter and linear phase FIR filter are designed to process the cascaded filtering and decimation of the demodulated signals. This method achieves a satisfying processing speed and filtering effect, and also reduces the data size obviously. The experiment based on the permanent magnetism resonance imaging system proves its effectiveness and practicability.

Observation on treatment of chronic pelvic inflammatory with point injection combined with ultra-laser radiation / 中国针灸

<p><b>OBJECTIVE</b>To probe into clinical therapeutic effect of point injection combined with ultra-laser radiation on chronic pelvic inflammatory.</p><p><b>METHODS</b>Sixty cases of chronic pelvic inflammatory were divided into a treatment group and a control group, 30 cases in each group. The treatment group were treated with point injection of Yuxingcao Injectio combined with ultra-laser point radiation, and the control group with simple point injection of Yuxingcao Injectio, once each day, for 4 weeks.</p><p><b>RESULTS</b>Twenty-eight cases were effective with a total effective rate of 93.3% in the treatment group, and 23 cases were effective with a total effective rate of 76.7%; the weighty pain of lower abdomen, abnormal leucorrhea and signs of gynecological examination, etc. in the treatment group significantly improved as compared with the control group (P<0.05).</p><p><b>CONCLUSION</b>Point injection combined with ultra-laser radiation has definite therapeutic effect on chronic pelvic inflammatory.</p>
