Methods Sixty obese patients with abnormal lipids and serum leptin were randomly divided into a dilatational wave group and a continuous wave group via random number table, with 30 cases in each group. They were divided by TCM differentiation into three types： stomachintestine excessive heat, weakness of the spleen-stomach and spleen-kidney yang deficiency, treated by electroacupuncture on Tianshu （天枢 ST 25）, Daheng （大横 SP 15）, Zusanli （足三里ST 36）, Shangjuxu （上巨虚 ST 37）, Fanglong （丰隆 ST 40）, Yinlingquan （阴陵泉 SP 9）, Quchi （曲池 LI 11）, Zhigou （支沟 TE 6） and Hegu （合谷 LI 4） along with thunder-fire moxibustion. The frequency of electro-acupuncture in the dilatational wave group and the continuous wave group was 2 Hz/100 Hz and 2 Hz, respectively. Patients in the two groups were treated once a day, six times a week. The treatment lasted for 4 weeks with 3-month follow-up. Body mass and body fat percentage before and after the treatment, as well as during the follow-up, were compared. The effectiveness rates in the two groups were compared, and the efficacy statistics of patients with different TCM patterns in the dilatational wave group were also analyzed. Lipid levels of the patients in two groups before and after the treatment were measured with an automatic biochemical analyzer, and serum leptin levels were detected with flow cytometry system. Results After the treatment, the patients＇ blood lipids, serum leptin levels, body mass and body fat percentage were effectively reduced in the two groups; three months＇ follow-up witnessed continuous decline of obesity indicators （P〈0.01 or P〈0.05）, and patients in the dilatat-ional wave group improved more significantly than those in continuous wave group （P〈0.05 or P〈0.01）. The efficacy in the dilatational wave group was superior to that in the continuous wave group （P〈0.01）. The best efficacy could be found among patients with weakness of the spleen and the stomach in the dilatational wave group. Conclusion Efficacy of treating obese patients with abnormity of lipids and serum leptin by electro-acupuncture combined with thunder-fire moxibustion in the dilatational wave group was significantly better than that of the continuous wave group, and efficacy for obese patients with weakness of the spleen and the stomach was superior to that of those with stomach-intestine excessive heat and spleen-kidney yang deficiency.展开更多

文摘由于不同井间工况差异显著,异常振动特征分布存在跨井不一致性,传统基于单井数据的监测方法难以适应跨井场景。为此,以黏滑振动为例,对不同工况下的黏滑振动数据特征进行了对比分析,提出了一种结合深度判别迁移学习网络(domain adaptive transfer learning network,DDTLN)与BO⁃Transformer⁃LSTM的跨井异常振动识别方法。将近钻头振动数据输入到DDTLN模型中,通过卷积层与改进的联合分布自适应(IJDA)机制减小域间特征差异,实现跨域特征提取;将提取的特征输入到BO⁃Transformer⁃LSTM模型中挖掘时序信息,实现跨井高效分类。试验结果表明:不同工况下井间振动信号差异显著,传统方法跨域分类效果较差;经过DDTLN处理后,不同域间的数据特征有了很好的对齐,跨域识别准确率高达91.5%;DDTLN⁃BO⁃Transformer⁃LSTM模型能够有效解决跨井识别问题,分类准确率最高达96.7%,显著优于传统单井识别方法,具有更好的泛化能力。该研究可为跨井场景下的井下异常振动识别提供新思路。
