Methods Fifty-one patients with renal colic were randomly divided into an electroacupuncture group （26 cases） and a medicine group （25 cases）. In the electroacupuncture group, electroacupuncture was applied to the Xi-cleft points of kidney and bladder meridians, named Shuǐquán （水泉 KI 5） and Jīnmén （金门 BL 63） as well as the relevant Front-mu points, Jīngmén （京门 GB 25） and Zhōngjí （中极 CV 3）. In the medicine group, intramuscular injection with Fortanodyn （100 mg） was administered. Once treatment was applied for immediate analgesia in each group. Before and after treatment, the Simplified McGill Pain Questionnaire （SF-MPQ） and the Visual Analogy Scale （VAS） were adopted for pain assessment respectively. The clinical efficacy and the recurrence of the disease were observed in the two groups. Results The clinically cured and remarkably effective rate was 69.2% （18/26） in the electroacupuncture group, which was superior to 44.0% （11/25） in the medicine group （P0.05）. Separately, in 10 min, 30 min, 60 min and 120 min after treatment, in either group, SF-MPQ and VAS scores were obviously reduced as compared with those before treatment （all P0.05）. The scores in 10 min and 30 min after treatment in the electroacupuncture group were reduced more remarkably as compared with those in the medicine group （both P0.05）. The complete remission time in the electroacupuncture group was shorter apparently than that in the medicine group [（131.19±152.12） min vs （184.29±84.04） min, P0.05]. The recurrence rate of renal colic in 24 h was 8.0% （2/25） in the electroacupuncture group, which was lower slightly than 31.6% （6/19） in the medicine group （P0.05）. Conclusion Renal colic can be effectively relieved in the treatment with either electroacupuncture at the Xi-cleft points and the Front-mu points of kidney and bladder meridians or intramuscular injection with Fortanodyn. But, the electroacupuncture therapy achieves much better efficacy.展开更多

文摘Point defect engineering endows catalysts with novel physical and chemical properties,elevating their electrocatalytic efficiency.The introduction of defects emerges as a promising strategy,effectively modifying the electronic structure of active sites.This optimization influences the adsorption energy of intermediates,thereby mitigating reaction energy barriers,altering paths,enhancing selectivity,and ultimately improving the catalytic efficiency of electrocatalysts.To elucidate the impact of defects on the electrocatalytic process,we comprehensively outline the roles of various point defects,their synthetic methodologies,and characterization techniques.Importantly,we consolidate insights into the relationship between point defects and catalytic activity for hydrogen/oxygen evolution and CO_(2)/O_(2)/N_(2) reduction reactions by integrating mechanisms from diverse reactions.This underscores the pivotal role of point defects in enhancing catalytic performance.At last,the principal challenges and prospects associated with point defects in current electrocatalysts are proposed,emphasizing their role in advancing the efficiency of electrochemical energy storage and conversion materials.
