The system architecture of vehicledurability emission test cell, the road load simulation strategy and the tele-monitoring systembased on Browser/Client structure are described. Furthermore, the construction of the robot driver,vehicle performance self-learning algorithm, multi-mode vehicle control model and vehicle speedtracking strategy based on fuzzy logic arealso discussed. Besides, the capability of controlparameters self-compensation on-line makes it possible to compensate the wear of vehicle componentsand the variety of clutch true bite point during the long term test. Experimental results show thattherobot driver can be applicable to a wide variety of vehicles and the obtained results stay withina tolerance band of ± 2 km/h. Moreover the robot driver is able to control tested vehicles withgood repeatability and consistency; therefore, this methodpresents a solution to eliminate theuncertainty of emission test results by human drivers and to ensure the accuracy and reliability ofemission test results.展开更多

English and Chinese databases were searched from their respective inceptions to March 2014. The reporting quality was assessed according to the "Consolidated Standards of Reporting Trials"(CONSORT) checklist for parallel RCTs and the revised "Standards for Reporting Interventions in Clinical Trials of Acupuncture"(STRICTA). A Meta-analysis was conducted to synthesize the effect sizes,and publication bias was evaluated by the Egger linear regression test using Stata.RESULTS: Ninety-seven studies were included, of which most lacked adequate reporting information, and 80.4% showed that the efficacy of abdominal acupuncture is superior to conventional body acupuncture, especially for the following diseases:lumbar disc herniation, cervical spondylosis, omarthritis and cervical vertigo, except simple obesity.Effect-sizes were controversial when evaluating different outcomes.CONCLUSION: The international standard CONSORT statement and STRICTA guidelines should be strictly applied when reporting acupuncture RCTs in the future. Abdominal acupuncture appears to be more effective compared with conventional body acupuncture for some diseases. However, further high quality blind RCTs using validated outcomeindexesandstandardreportingarewarranted.展开更多

METHORDS： A literature search of the following electronic databases from their inception to Febru- ary 2013 was conducted： Chinese Biomedical data- bases, Chinese National Knowledge Infrastructure, Wanfang Database, China Science and Technology Journal Database, Cochrane Library, Web of Sci- ence, MEDLINE, and EMBASE. Randomized con- trolled trials where CHM had been used to treat LDH were selected. Data extraction, quality assess- ment, and data analysis were carried out by two in- dependent reviewers. RESULTS： Of the 2415 studies identified, eight with complete data on 1146 patients were selected. The methodological quality was poor in all trials. Five studies reported that CHM was better than WesternMedicine [OR=2.81, 95% CI （1.27, 6.18）; OR=3.34, 95% CI （1.92, 5.79）; 0R=2.22, 95% CI （1.08, 4.57）; OR= 6.67, 95% CI （1.34, 33.28）; and OR=1.94, 95% CI （1.23, 3.06）]. Two studies reported that the clinical outcome was better in CHM groups than in physio- therapy and placebo groups, [OR=3.02, 9.5% CI （1.08, 8.46）; and OR=2.67, 95% CI （1.26, 5.64）, re- spectively], whereas one study reported no differ- ence between CHM and physiotherapy groups. One study reported that CHM resulted in higher Japanese Orthopedic Association scores [MD=7.78, 95% CI （6.67, 8.89）] than in a control group and an- other that participants treated with CHM had lower Visual Analogue Scale scores [MD=- 0.72, 95% CI （ - 0.86, 0.58）] than those in a control group. Three studies reported that the adverse effects of CHM and Western Medicine did not differ signifi- cantly [OR=0.10, 95% CI （0.01, 1.85）; OR=0.19, 95% CI （0.01,4.07）; and OR=O.07, 95% CI （0.00, 1.32）]. CONCLUSION： CHM may be more effective than other interventions for LDH; however, methodologi- cal weaknesses in the studies assessed in this re- view prevent a definitive conclusion. More high-quality large-scale studies are required to clar- ify this matter.展开更多
