BACKGROUND: It was found that moxibustion can inhibit the inflammatory factors in the serum of rats with cerebral ischemia/reperfusion injury, resist oxidative stress, inhibit cell apoptosis, and effectively reduce cerebral ischemia/reperfusion injury. OBJECTIVE: To observe the effects of different moxibustion intervention time on the expression levels of nucleotide binding oligomerization domain-like protein 3 inflammasome (NLRP3), cysteine aspartase (caspase-1), apoptosis-related speck-like protein, exfoliatin-D protein, interleukin-1β and interleukin-18 in rats with cerebral ischemia/reperfusion injury, and to explore its action mechanism. METHODS: SD rats were randomly divided into sham operation group (n=9) and operation group (n=36). The model of focal cerebral ischemia/reperfusion injury was established by middle cerebral artery occlusion in the operation group. After successful modeling, the rats in the operation group were further divided into model group, moxibustion 10-minute group, moxibustion 15-minute group and moxibustion 30-minute group, with 9 rats in each group. Rats in the moxibustion 10-minute, 15-minute and 30-minute groups were given moxibustion at “Baihui, Dazhui and Zusanli”, respectively, once a day for a total of 7 days. The neurological deficits of rats were evaluated by LONGA method. The cerebral infarction was observed by 2,3,5-triphenyltetrazolium chloride staining. The pathological changes of brain tissue were observed by hematoxylin-eosin staining. The contents of interleukin-1β and interleukin-18 in serum of rats in each group were detected by ELISA. Immunohistochemistry and western blot assay were used to detect the expression levels of NLRP3, caspase-1, apoptosis-related spot-like protein and gasdermin D in the ischemic cortex of rats in each group. RESULTS AND CONCLUSION: Compared with the sham operation group, the neurological deficit score of the model group was significantly increased (P < 0.01). Compared with the model group, the neurological deficit score of the moxibustion groups was significantly reduced (P < 0.01). Compared with the sham operation group, the infarct volume of the model group was significantly increased (P < 0.01). Compared with the model group, the infarct volume of the moxibustion groups was significantly reduced (P < 0.01); the infarct volume of the rats was smallest in the moxibustion 30-minute group (P < 0.05). Compared with the model group, the contents of inflammatory factors interleukin-1β and interleukin-18 in the serum of rats in the moxibustion groups were decreased (P < 0.01). Compared with the moxibustion 10-minute group, the contents of inflammatory factors in the serum of rats in the moxibustion 30-minute group were significantly decreased (P < 0.05). Compared with the model group, the expression of NLRP3, apoptosis-related spot-like protein, Caspase-1 and gasdermin D protein in the ischemic cortex of the moxibustion groups was significantly decreased (P < 0.01). Compared with the moxibustion 10-minute and 15-minute groups, the expression of protein in the moxibustion 30-minute group was significantly decreased (P < 0.05). It is concluded that moxibustion at Baihui, Dazhui and Zusanli can reduce cerebral ischemia/reperfusion injury, among which moxibustion for 30 minutes has the best effect, and its mechanism may be related to the inhibition of pyroptosis mediated by NLRP3/Caspase-1 pathway.

BACKGROUND: Pretreatment with moxibustion is a preventive treatment in traditional Chinese medicine. Pretreatment with moxibustion at the onset of prodromal symptoms can significantly reduce the symptoms and delay the onset of many diseases, but the exact mechanism remains to be studied. OBJECTIVE: To investigate the mechanism of SIRT1/FoxO3 pathway in moxibustion pretreatment to ameliorate oxidative stress injury in cerebral ischemiareperfusion model rats. METHODS: Forty-eight Sprague-Dawley rats were randomly divided into sham-operated group, model group, moxibustion pretreatment group, and moxibustion pretreatment+EX527 (SIRT1 inhibitor) group, with 12 rats in each group. The moxibustion pretreatment group was given moxibustion with seedsized moxa cone at Baihui, Dazhui, and Zusanli before modeling, three moxa-cones per acupoint, once a day for 7 days. In the model group, moxibustion pretreatment group and moxibustion pretreatment+EX527 group, the rat model of middle cerebral artery occlusion was made by suturing of the middle cerebral artery 30 minutes after the last moxibustion. After 2 hours of cerebral ischemia, the middle artery suture was removed and the rats were reperfused for 12 hours. In the sham-operated group, only the common carotid artery, internal carotid artery, and external carotid artery were dissected without suturing the middle cerebral artery. In the moxibustion pretreatment+EX527 group, EX527 (15 mg/kg) was given intraperitoneally 30 minutes before each moxibustion. After 12 hours of reperfusion, the rats were scored for neurological deficits, and the cerebral infarct volume was calculated by 2,3,5-triphenyltetrazolium chloride staining method. The levels of oxidative stress factors in the infarcted tissues were detected by the kit method, and western-blot method was used to detect the expression levels of SIRT1, FoxO3, p-FoxO3 and brain-derived neurotrophic factor in the ischemic area of the cerebral cortex. RESULTS AND CONCLUSION: After 12 hours of reperfusion, the neurobehavioral score in the model group was significantly higher than that in the shamoperated group (P < 0.01), while the score in the moxibustion pretreatment group was significantly lower than that in the model group (P < 0.01) and moxibustion pretreatment+EX527 group (P < 0.05). There were no obvious infarct foci in the brain tissue of the sham-operated rats, but obvious ischemic foci were observed in the right side of the brain tissue of the rats in the model group (P < 0.01). The right infarct volume in the moxibustion pretreatment group was significantly reduced compared with the model group (P < 0.01), while the right infarct volume in the moxibustion pretreatment+EX527 group was significantly enlarged compared with the moxibustion pretreatment group. After 12 hours of reperfusion, the level of malondialdehyde was significantly elevated (P < 0.01) and the expression of superoxide dismutase was significantly decreased (P < 0.01) in the model group compared with the sham-operated group. The levels of malondialdehyde was significantly decreased (P < 0.01, P < 0.05) and the expression of superoxide dismutase was significantly increased (P < 0.01, P < 0.05) in the moxibustion pretreatment group compared with the model group and the moxibustion pretreatment+EX527 group. Western blot results showed that the expression levels of SIRT1, FoxO3, p-FoxO3, and brain-derived neurotrophic factor proteins were significantly higher in the model group compared with the sham-operated group (P < 0.01); compared with the model group, the expression levels of SIRT1, FoxO3, and brain-derived neurotrophic factor were significantly higher in the moxibustion pretreatment group (P < 0.01), and p-FoxO3 expression was significantly lower (P < 0.01); compared with the moxibustion pretreatment+EX527 group, the expression levels of SIRT1, FoxO3, and brain-derived neurotrophic factor were elevated in the moxibustion pretreatment group (P < 0.05), and no statistically significant difference was found in the p-FoxO3 expression (P > 0.05). To conclude, moxibustion pretreatment can significantly improve neurological function in rats after cerebral ischemia-reperfusion, and the mechanism may be related to the activation of SIRT1/FoxO3 pathway to reduce oxidative stress injury in the rat model of cerebral ischemia-reperfusion.

MXene material has the advantages of flexible composition and high capacitance, which has attracted much attention in the field of supercapacitor energy storage. Tn this work, the poly (3, 4-ethylenedioxythio-phene)/MXene (PEDOT/MXene) composite electrode material were synthesized via electrochemical method. Experimental results indicate that the specific capacitance of PEDOT/MXene reaches 250.21 mF/cmJ at a scan rate of 30 m V/s. With the current density increasing from 0.1 mA/cmJ to 5 m A/cmJ, the specific capacitance retention of PEDOT/MXene achieves 83.5%, was much better than PEDOT (64.1%). Additionally, the initial specific capacitance of PEDOT/MXene still remains 84% over 1000 cycles at a scan rate of 1000 mV/s by CV method, exhibiting good rate performance and cycle stability. This work provides a new approach to construct high-performance energy storage interface with MXene-based materials. [ABSTRACT FROM AUTHOR]

[Objective] The study aimed to reveal the microbial community structure and soil physicochemical properties of apple rhizosphere under the intercropping system of persimmon and apple trees. [Method] In the study, rhizosphere soil of intercropping (I) and non-intercropping (NI) apples were used as materials to analyze the rhizosphere microbial community structure by high-throughput sequencing technology. [Result] lnter-cropping of persimmon significautly increased the contents of organic matter (OM), available nitrogen (AN), total phosphorus (TP), decreased the contents of available potassium (AK) in apple rhizosphere soil. The Alpha diversity analysis showed that intercropping had no significant effect on the bacterial richness index and diversity index of apple rhizosphere soil, whereas significantly reduced the Ace index of rhizosphere soil fungi (P = 0. 03). β diversity analysis showed that there were significant differences in bacterial and fungal community structure between intercropped and non-intercropped soils. Further LEfSe analysis showed that intercropping significantly increased the abundance of 17 bacterial genera in apple rhizosphere soil, of which, 9 were known genera, and 8 were unknown genera. These nine known genera included Sporacetigenium, Tepidisphaera, Agromyces, Alkanindiges, Phycisphaera, Pseudoxanthomonas, Terrimonas, Pseudohaliea, Paenisporosarcina; The abundances of four bacterial genera, namely Sporichthya, Methylocystis, Devosia and Alter-erythrobacter were significantly decreased. Intercropping significantly increased the abundance of 1 fungal genus Arthrographis and decreased the abundance of 3 fungal genera, namely Cylindrocarpon, Metacordyceps and Exophiala. Spearman's correlation analysis showed that Pseudomonas was positively correlated with available phosphorus (AP) and TP, while Naganishia was positively correlated with AP. The fungal genera Polyscytalum and Minimedusa showed a significant negative correlation with AP. PICRUSt2 functional prediction analysis showed that intercropping significantly decreased the abundance of carbohydrate transport and metabolism, and extracellular structure in rhizosphere bacteria. FUNGuild analysis showed that intercropping significantly reduced the abundance of pathogen-saprophytic transitional fungi in apple rhizosphere soil. [Conclusion] Intercropping of apple and persimmon trees can increase the contents of OM, AN, TP in apple rhizosphere soil, significantly increase the relative abundance of beneficial rhizosphere microorganisms, and reduce the relative abundance of pathogenic fungi microorganisms, which will provide data reference for exploring the mechanism of intercropping disease resistance.

Biochar is one of the most important soil amendment materials. An ever increasingly prominent role can be found in carbon sequestration and greenhouse gas, especially in the methane (CH4) and nitrous oxide (N2O) mitigation potential. Among them, humic acid amendments to the cropland have dominated the C, N cycling and yield. In this study, a systematic investigation was implemented to clarify the influencing mechanisms of the biochar and humic after one year of application on global warming potential (GWP) and greenhouse gas intensity (GHGI) of CH4 and N2O emissions under a rice-wheat rotation system. A field experiment was designed with the double factors randomized block design in an acidic paddy of Hangzhou, Zhejiang Province, China. Six treatments were conducted in 2020 before the rice seedlings were transplanted as control without biochar or humic acid (B0F0), 0.6 t/hm² humic acid without biochar (B0F1), 1.2 t/hm² humic acid without biochar (B0F2), 20 t/hm² biochar without humic acid (B1F0), 0.6 t/hm² humic acid with 20 t/hm² biochar (B1F1), and 1.2 t/hm² humic acid with 20 t/hm² biochar (B1F2). The CH4 and N2O emissions were then measured in the different treatments one year later in 2021-2022. An evaluation was also performed on the one-year field-aged biochar and humic acid amendment in a typical rice-wheat rotation system. The results showed that after application of one year 1) the biochar increased the soil organic carbon (SOC) content both in rice and wheat season; Humic acid significantly increased the SOC content in the rice season, whereas, there was no significant effect on the SOC in the wheat season. Meanwhile, there was no effect on rice yield in the application of biochar alone, humic acid alone and application of biochar and humic acid together, compared with the B0F0 treatment. The application of biochar and humic acid together significantly increased the wheat yield by 1.0%-5.0%. 2) The application of biochar and humic acid addition reduced the cumulative CH4 emissions by 11.1%, 21.8%-25.8% and 24.7%-34.1%, compared with the B0F0 treatment, but the cumulative N2O emissions were promoted by 33.3%, 10.0%-30.1% and 7.2%-23.7%, respectively. 3) The estimated gross GWP of CH4 plus N2O among the treatments was significantly reduced by the application of biochar and humic acid. The reason was attributed to the reduction of cumulative CH4 emissions. In addition, the biochar and humic acid addition significantly reduced the GHGI during the whole rice and wheat season, in terms of greenhouse gas emissions and yield. The application of biochar and humic acid reduced the GHGI by 10.2%, 17.3%-20.2%, and 27.2%-36.2%, respectively, compared with the B0F0 treatment. The lowest GWP and GHGI were achieved in the B1F1 treatment (biochar and humic acid were added at the rate of 20 and 0.6 t/hm², respectively) among all the treatments. Consequently, outstanding performance can be expected in biochar and humic acid after the application of one year of the GHGs mitigation and carbon sequestration. A beneficial measure can also be utilized to improve the grain yields with less greenhouse gas emission in the rice-wheat rotation system. [ABSTRACT FROM AUTHOR]

Objective To explore the effects of two different administration methods on the results of bronchodilation test of children's pulmonary ventilation function. Methods From October 2021 to March 2022, a total of 114 children aged 5-12 who underwent bronchodilation test of pulmonary ventilation function and were diagnosed as cough variant asthma (CVA) or bronchial asthma (BA) in the children's lung function room of Nanchong central hospital were selected as the research objects. They were randomly divided into the aerosol group (56 cases) and the atomization group (58 cases). The aerosol group was given bronchodilator by pressurized metered dose inhaler (pMDI), while the atomization group was given bronchodilator by aerosol inhalation. Then the effects of two administration methods on the results of bronchodilation test were compared. Results The forced expiratory volume in one second (FEV1)/forced vital capacity (FVC), forced expiratory flow 50 (FEF50), FEF75 and maximum mid-expiratory flow (MMEF) of children in the aerosol group were significantly higher than those before administration, and the differences were statistically significant (P＜0. 05). The FEV1, FEV1/FVC, peak expiratory flow (PEF), FEF50, FEF75, MMEF of children in the atomization group were significantly higher than those before administration, and the differences were statistically significant (P＜0. 05). The improvement rates of FEV1, FEV1/FVC, FEF50 and MMEF of children in the atomization group were significantly higher than those in the aerosol group, and the differences were statistically significant (P＜0. 05). Conclusion The method of aerosol inhalation is superior to the aerosol group in diastolic effect, and can effectively improve the pulmonary function level of children, which is worth popularizing in clinic.

BACKGROUND: Zirconium implants are used in the field of oral implants due to good biocompatibility. Because of its biological inertness, the surface of the implant needs to be modified to improve its bioactivity. Hydroxyapatite coating is a widely used modification technique for implant surfaces. OBJECTIVE: The phase-transition lysozyme was modified on the zirconia surface, based on which a hydroxyapatite coating was constructed to confer its bioactivity and improve the success rate of implants. METHODS: The phase-transition lysozyme solution was dropped onto the surface of the smooth zirconia specimen for 2 hours. The phase-transition lysozymemodified zirconia specimen was incubated in the simulated body fluid for 10 days to induce the hydroxyapatite coating. The contact angle, roughness and mechanical properties of unmodified zirconia specimens, phase-transition lysozyme-modified zirconia specimens and hydroxyapatite-coated zirconia specimens were tested. The three kinds of zirconia specimens were co-cultured with MC3T3-E1 cells, separately. The cell proliferation and alkaline phosphatase activity were detected. Unmodified zirconia specimens and hydroxyapatite-coated zirconia specimens were co-cultured with MC3T3-E1 cells, separately, and cell adhesion was observed under a scanning electron microscope. RESULTS AND CONCLUSION: (1) The contact angle of the hydroxyapatite coating group was smaller than that of the unmodified group (P < 0.05), and the roughness was greater than that of the unmodified group (P < 0.05). There was no significant difference in the Vickers hardness and fracture strength of the three groups of specimens (P > 0.05). (2) CCK-8 assay showed that the absorbance values of cell proliferation in the hydroxyapatite coating group on 3, 5, and 7 days of culture were higher than those in the phase-transition lysozyme group and the unmodified group (P < 0.05). The alkaline phosphatase activity of the hydroxyapatite coating group was higher than that of the phase-transition lysozyme group and the unmodified group at 7 and 14 days of culture (P < 0.05). (3) Scanning electron microscope showed that MC3T3-E1 cells adhered closely to the surfaces of the two kinds of zirconia materials after 12 hours of culture. After 3 days of culture, the number of cells on the surfaces of the two materials increased, and the number of cells in the hydroxyapatite coating group was high and cell junctions appeared. (4) The results show that for zirconia all-ceramic materials, the preparation of hydroxyapatite coating on the basis of phase-transition lysozyme modification can improve its hydrophilicity and cytocompatibility without affecting the mechanical properties of the material.
