To observe the clinical effect of penetrating moxibustion on migraine without aura (MO) patients.Totally 60 MO patients from the Acupuncture Clinic of the Third Affiliated Hospital of Henan University of Chinese Medicine were collected from November 2015 to February 2017. All patients were assigned to a treatment group and a control group using a random number table, 30 cases in each group. The treatment group was treated with penetrating moxibustion, and the control group was treated with mild moxibustion, thrice a week for 4 consecutive weeks. The total effective rate, Visual Analogue Scale (VAS) scores, headache intensity, and Migraine Specific Quality of Life Questionnaire (MSQ) scores of patients after treatment were compared between the two groups. The moxibustion sensation and reaction after moxibustion were observed, and the adverse reactions were evaluated. All patients were followed up at 4 and 16 weeks after treatment.The total effective rate of the treatment group was significantly higher than that of the control group (93.33% vs. 80.00%, P0.05). The improvement of VAS scores, headache intensity, and the role restrictive and role preventive scores in MSQ in the treatment group was better than those in the control group (P0.05). The person-time of moxibustion sensations of itching, numbness and cold as well as flushing and sweating after moxibustion in the treatment group was all significantly higher than that in the control group (P0.01). There was no significant difference in safety evaluation between the two groups (P0.05).Penetrating moxibustion can significantly relieve pain and improve quality of life of MO patients. After penetrating moxibustion, flushing and sweating of patients were obvious, and the curative effect was superior to the mild moxibustion.

In this paper, Ag@Fe3O4@cellulose nanocrystals (CNC) nanocomposites were synthesized by a facile and green microwave-assisted hydrothermal method. In the procedure, CNC was used as a reducing agent for the synthesis of Ag. During the whole synthesis process, there were no additional reducing agents or toxic solvents used. The nanocomposites were characterized by X-ray powder diffraction, scanning electron microscopy, energy-dispersive X-ray spectrum, transmission electron microscopy, thermogravimetric analysis, and differential thermal analysis. In addition, Ag@Fe3O4@CNC nanocomposites were also synthesized by microwave-assisted method and hydrothermal method. Both the effects of reaction time and synthetic procedures on the reduction process of Ag+ by CNC were explored. The results showed that Fe3O4 was formed with sphere-like structure and dispersed uniformly. Ag@Fe3O4@CNC nanocomposites exhibited good adsorption of dye solution, which showed potential applications in water treatment. The antibacterial results showed that Ag@ Fe3O4@CNC nanocomposites had good antibacterial activities toward both Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). The green and facile strategy reported in this paper may be broadly used in synthesizing other metal nanoparticles, as well as organic–inorganic nanocomposites.

A series of HPW/PEHA/ZrSBA-15 catalysts with varied Zr contents were synthesized and used for the selective oxidation reaction of benzyl alcohol. The catalysts were characterized by N2 adsorption–desorption, XRD, SEM, TEM, XPS, FT-IR and ICP-AES analysis techniques. It was found that, through simply tuning the initial molar ratios of Zr/Si, both the morphology and catalytic performance of resultant catalysts can be tailored. More interestingly, the incorporation of zirconium ions, which can endow the ordered framework with enhanced acidity, can effectively stabilize loaded pentaethylenehexamine (PEHA) and facilitate a higher dispersion and attraction of HPW clusters. By carefully screening the catalytic results of the selective oxidation of benzyl alcohol, an optimal value of Zr/Si molar ratio was found to be 0.05, under which platelet ZrSBA-15 with ordered framework can be facilely obtained, leading to a maximum catalytic activity with negligible loss in selectivity and conversion even after five times of recycling test.

Heteropolyacid-based catalysts with molecular level distributions of surface functionalities were synthesized by anchoring phosphotungstic acid (HPW) onto the pentaethylenehexamine (PEHA) layers stabilized by platelet ZrSBA-15 with short mesochannels. Namely, the presence of zirconium species in pore walls could significantly improve the surface acidity to attract and stabilize PEHA species, leading to a stronger interaction between them and a superiority to make HPW species highly stable. Standard characterizations of XRD, SEM, TEM, FT-IR, TG, N2 adsorption–desorption and N elemental analyses were preserved to demonstrate the synergistic effect. The resulting composite were investigated for the oxidation of benzaldehyde to benzoic acid in the H2O2-mediated environment, the catalyst 25 % HPW/PEHA/ZrSBA-15 screened high yield for benzoic acid (~99.7 %). Besides, various reaction parameters such as reaction temperature, reaction time, the amount of hydrogen peroxide and catalyst reusability were also investigated for the oxidation of benzaldehyde to benzoic acid with a target to confirm the validity of the catalyst.
