RESUMEN

To overcome the disadvantages of poor intrinsic conductivity and stability of ZnCo2O4, a ZnCo2O4@MnMoO4 composite as an emerging pseudocapacitor electrode material with high specific capacitance, environmental friendliness, morphological diversity, and unique hierarchical structure was synthesized via a simple two-step hydrothermal method. The research results indicate that the ZnCo2O4@MnMoO4 composite can present a high specific capacity of 1628 F g-1 at a current density of 1 A g-1 and good cycling stability with 69% capacity retention after 10 000 cycles at 10 A g-1. Hybrid supercapacitors (HSCs) assembled with the ZnCo2O4@MnMoO4 cathode and activated carbon anode can deliver an energy density of 48 W h kg-1 at a power density of 695 W kg-1, and their capacity retention reached 61% after 8000 charge-discharge cycles at a current density of 10 A g-1. This could be attributed to the synergistic effect of the specific surface area and electrical conductivity enhanced by compositing ZnCo2O4 with MnMoO4. As a result, the excellent electrochemical properties show that the ZnCo2O4@MnMoO4 composite has strong application potential for high-performance supercapacitors.

RESUMEN

OBJECTIVE: To compare the efficacy of the patients of xerosis conjunctivitis with liver and kidney yin deficiency among the combined therapy of acupuncture and Shi's manipulation, common acupuncture and artificial tears therapy. METHODS: One hundred and eight patients were randomized into an acupuncture group, a SHI's manipulation group and an artificial tears group, 36 cases in each group. A total of 15 cases dropped out before the end of the study, including 4 cases in the acupuncture group, 6 cases in the SHI's manipulation group, and 5 cases in the artificial tears group. In the acupuncture group, acupuncture was applied to Jingming (BL 1) and Qiuhou (EX-HN 7) on the affected side, and the bilateral Sanyinjiao (SP 6) and Taixi (KI 3). The needles were retained for 20 min. In the SHI's manipulation group, on the basis of the treatment as the acupuncture group, Shuigou (GV26) was added and stimulated with SHI's acupuncture manipulation. In these two groups, acupuncture was given 3 times a week totally for 3 weeks. In the artificial tears group, sodium hyaluronate eye drops were used, 5 times a day, for 3 weeks totally. Separately, before treatment, at the moment after the 1st treatment and 3 weeks after treatment, the subjective symptom score, Schirmer I test, breakup time (BUT) of tear film were observed in each group. RESULTS: (1) Subjective symptom score: at the moment after the 1st treatment and 3 weeks after treatment, the scores in each group were all reduced significantly as compared with those before treatment (all P < 0.05). At the moment after the 1st treatment, the score in the SHI's manipulation group and the artificial tears group was reduced apparently as compared with that in the acupuncture group (both P < 0.05). In 3 weeks of treatment, the score in the SHI's manipulation group was reduced apparently as compared with the acupuncture group and the artificial tears group (both P < 0.05). (2) For Schirmer I test, at the moment of the 1st treatment, the result in the SHI's manipulation group and the artificial tears group was improved significantly as compared with that before treatment (both P < 0.05). In 3 weeks of treatment, the result in the acupuncture group and the SHI's manipulation group group was improved significantly as compared with that before treatment (both P < 0.05). At the moment of the 1st treatment, the result in the artificial tears group was improved significantly as compared with the acupuncture group and the SHI's manipulation group (both P < 0.05). In 3 weeks of treatment, the result in the acupuncture group and the SHI's manipulation group was better than that in the artifi-cial tears group separately (both P < 0.05). (3) For BUT, the result in the acupuncture group and the SHI's manipulation group was prolonged significantly as compared with that before treatment and was prolonged apparently as compared with that in the artificial tears group (both P < 0.05) in 3 weeks of treatment. CONCLUSION: The intervention of SHI's acupuncture manipulation relieves the subjective symptoms of xerosis conjunctivitis of liver and kidney yin deficiency and achieves the same efficacy as the common acupuncture and artificial tears treatment. It does not present the apparent advantages as the common acupuncture in the short term for promoting the tear secretion and tears film repair.
