| 1 | Systematic review and Meta-analysis of acupuncture and acupoint catgut embedding for the treatment of abdominal obesity显示文摘OBJECTIVE:To systematically review and analyze the effect of acupuncture and acupoint catgut embedding in treatment of abdominal obesity to provide a more reasonable clinical treatment regimen.METHODS:Ten databases were searched as of August 2022:the English databases Pub Med,Embase,Cochrane Library,Web of Science,Wiley,and Scopus and the Chinese databases China National Knowledge Infrastructure Database,China Science and Technology Journal Database,Wanfang,and Sino Med/Chinese Biomedical Literature Database.Randomized controlled trials(RCTs)of acupuncture and acupoint catgut embedding as the main interventions to treat abdominal obesity were extracted.The investigators imported the citations into End Note version X9.1 for deduplication,screening,extraction,and integration.The risk of bias in the included RCTs was assessed according to the Cochrane Handbook.Rev Man 5.4 software was used to conduct a Meta-analysis of RCTs that met the inclusion criteria.RESULTS:Thirteen RCTs(1069 patients)were included in this study,and the data of eleven RCTs(966 patients)were include in the Meta-analysis.The results showed that acupoint catgut embedding can significantly change the weight and waist circumference of patients with abdominal obesity when compared to sham acupuncture or no treatment[mean difference(MD)=2.32,95%confidence interval(CI)(1.88,2.76),P<0.00001],[MD=3.47,95%CI(1.99,4.94),P<0.00001].The change in hip circumference after acupuncture was also significant[MD=0.89,95%CI(0.12,1.66),P=0.02].CONCLUSION:This study found that acupuncture and acupoint catgut embedding can effectively treat abdominal obesity,therefore,these interventions can be used as clinical supplements and alternative therapies.The diagnostic criteria of the existing studies and the intervention measures of the control group are not unified.It will be necessary to improve the clinical study protocols and expand the sample size to further validate the reliability of the results obtained of this study. | YE Wujie XING Jingyu YU Zekai HU Xingang ZHAO Yan | 2022 | Journal of Traditional Chinese Medicine2022，42，6： | 0 |
| 2 | Constructing Donor-Resonance-Donor Molecules for AcceptorFree Bipolar Organic Semiconductors显示文摘Organic semiconductors with bipolar transporting character are highly attractive as they offer the possibility to achieve high optoelectronic performance in simple device structures.However,the continual efforts in preparing bipolar materials are focusing on donor-acceptor(D-A)architectures by introducing both electron-donating and electron-withdrawing units into one molecule in static molecular design principles.Here,we report a dynamic approach to construct bipolar materials using only electron-donating carbazoles connected by N-P=X resonance linkages in a donor-resonance-donor(D-r-D)structure.By facilitating the stimuli-responsive resonance variation,these D-r-D molecules exhibit extraordinary bipolar properties by positively charging one donor of carbazole in enantiotropic N^(+)=P-X-canonical forms for electron transport without the involvement of any acceptors.With thus realized efficient and balanced charge transport,blue and deep-blue phosphorescent organic light emitting diodes hosted by these D-r-D molecules show high external quantum efficiencies up to 16.2%and 18.3%in vacuum-deposited and spin-coated devices,respectively.These results via the D-r-D molecular design strategy represent an important concept advance in constructing bipolar organic optoelectronic semiconductors dynamically for high-performance device applications. | He Jiang Jibiao Jin Zijie Wang Wuji Wang Runfeng Chen Ye Tao Qin Xue Chao Zheng Guohua Xie Wei Huang | 2021 | Research2021，，1： | 0 |
