＜正＞ Our previous study has demonstrated that electroacupuncture （ EA） produces antinociceptive effect,whereas the antinociception of intrathecal. but not intrac-erebroventricular, morphine is paradoxically attenuated after EA stimulation,indicating that EA activates two opposing systems （i.e.. opioid and anti - opioid systems）. In this study,we examined the involvement of cholecystokinin （CCK） in the anti - opioid property following EA stimulation in the spinal cord. EA was applied to ST - 36 acupoints. and pain thresholds were assessed by the hind -paw pressure test in male Sprague - Dawley rats. The amount of mRNA expression of CCK and its receptors （CCK - 1 and CCK - 2） in the spinal cord were determined by reverse transcriptase- polymerase chain reaction. The attenuation of morphine - induced antinociception after EA was significantly reversed by proglumide, CCK receptor antagonist. And the expression of CCK and CCK - 2 receptor mRNA in the spinal cord was markedly increased after EA stimulation. These results suggest that CCK mediated - neural systems in the spinal cord may be involved in the attenuation of antinociceptive effect of morphine after EA.

The immune-stromal cell interactions play a key role in health and diseases. In periodontitis, the most prevalent infectious disease in humans, immune cells accumulate in the oral mucosa and promote bone destruction by inducing receptor activator of nuclear factor-κB ligand (RANKL) expression in osteogenic cells such as osteoblasts and periodontal ligament cells. However, the detailed mechanism underlying immune–bone cell interactions in periodontitis is not fully understood. Here, we performed single-cell RNAsequencing analysis on mouse periodontal lesions and showed that neutrophil–osteogenic cell crosstalk is involved in periodontitis-induced bone loss. The periodontal lesions displayed marked infiltration of neutrophils, and in silico analyses suggested that the neutrophils interacted with osteogenic cells through cytokine production. Among the cytokines expressed in the periodontal neutrophils, oncostatin M (OSM) potently induced RANKL expression in the primary osteoblasts, and deletion of the OSM receptor in osteogenic cells significantly ameliorated periodontitis-induced bone loss. Epigenomic data analyses identified the OSM-regulated RANKL enhancer region in osteogenic cells, and mice lacking this enhancer showed decreased periodontal bone loss while maintaining physiological bone metabolism. These findings shed light on the role of neutrophils in bone regulation during bacterial infection, highlighting the novel mechanism underlying osteoimmune crosstalk.

一、引言2022年,日本央行前行长黑田东彦在日本经济团体联合会(Keidanren)会议上指出,日本“正在接近打破长期低通胀和低增长的关键时刻”。回首望去,2023年的确是朝着转型迈进的一年。日本经济已转向温和复苏,主要体现在经济活动正常化、供给侧约束减弱,产出缺口已改善至0%左右。以消费者价格指数(CPI)衡量的日本通胀率持续超过2%,这主要是由于过去进口价格上涨传递至消费价格.

一、引言2024年3月18日至19日,日本央行在结束为期两天的货币政策会议后,宣布调整货币政策框架,希望以可持续和稳定的方式实现物价稳定目标。日本央行认为,自2013年4月推出量化和质化宽松货币政策(QQE)以来,长达11年的大规模货币宽松政策实施效果明显。本文就日本央行对经济形势和物价走势的评估情况做简要介绍,其中包含了2024年4月底发布的《经济形势和物价走势展望报告》(以下简称《展望报告》)的内容,并就日本央行新货币政策框架详细内容和未来货币政策实施谈几点思考。
