目的观察浅针刺激镇静、山根穴治疗原发性失眠的疗效,并探讨其对血清下丘脑-垂体-肾上腺轴(HPA轴)激素促肾上腺皮质激素(ACTH)、皮质醇(COR)、促肾上腺皮质激素释放激素(CRH)的影响。方法选取2022年8月—2023年9月在福建中医药大学附属康复医院门诊就诊的原发性失眠患者60例,按照随机数字表法分为对照组和观察组各30例,最终对照组完成30例,观察组完成29例。对照组给予艾司唑仑片,临睡前30 min服用,每日1片,7 d为1疗程,共2个疗程。观察组取镇静、山根穴进行浅针手法治疗,每周治疗5次,5次为1个疗程,共2个疗程,中间间隔2 d。观察2组治疗前后匹兹堡睡眠质量指数量表(PSQI)总分及各项评分,外周血清中ACTH、COR、CRH含量的变化,并比较2组临床疗效。结果与治疗前比较,治疗后2组的血清ACTH、COR、CRH含量,PSQI总分及各项评分均降低(P0.05)。结论浅针疗法治疗原发性失眠有效,尤其是在提高日间功能障碍评分方面优于常规治疗,其作用机理可能与降低血清中HPA轴激素ACTH、COR、CRH含量有关。

Zeolitic imidazolate frameworks(ZIFs)are an important subclass of metal-organic frameworks(MOFs)with zeolite-type topology,which can be fabricated under ambient synthesis ***,the applications of ZIFs are commonly limited due to the weak hydrostability of their metal–ligand coordination bonds,particularly under humid and aqueous *** this work,as an example,the hydrolysis behaviours of ZIF-L with a special focus on ZIF-L coatings were tested at aqueous conditions with a wide range of pHs to systematically study and fundamentally understand their structural stability and degradation *** ZIF-L powder and ZIF-L coatings were severely damaged after only 24 h in aqueous ***,the ZIF-L coatings showed two distinct hydrolyzation pathways regardless of pH conditions,exhibiting either a ring-shaped etching or unfolding *** the ZIF-L powders were hydrolyzed almost identically across all pH *** this new understanding,a facile silk fibroin(SF)protein modification method was developed to enhance the hydrostability of ZIF-L coatings in aqueous *** effect of protein concentration on surface coating was systemically ***-L coating retained its surface morphology after soaking in water and demonstrated switchable super wetting properties and superior separation performance for oil/water *** a result,the quick SF protein modification significantly enhanced the stability of ZIF-L coatings under various pHs,while retaining their switchable wetting property and excellent separation performance.

Panax notoginseng-steamed chicken (PNSC) is a common medicinal diet in China. In this study， we conducted comprehensive analysis to determine the effect of PNSC on uterine involution in postpartum mice and human umbilical vein endothelial cells. The role of the PI3K/AKT/mTOR pathway in this process was explored. Results showed that PNSC promoted the recovery of endometrial hyperplasia and uterine index in postpartum mice. In vitro and in vivo experiments indicated that PNSC activated PI3K/AKT/mTOR signaling pathway， promoted the proliferation of human umbilical vein endothelial cells (HUVEC)， up-regulated the expression of VEGF， and its binding to VEGFR2. Moreover， it increased the expression of PCNA， MMP9， and CyclinD1 in the nucleus. Moreover， it up-regulated the secretion of hormones， such as prolactin (PRL)， progesterone (P)， as well as the level of vascular endothelial growth factor (VEGF) in mice， and down-regulated the secretion of endothelin-1 hormones (ET-1)， thereby promoting uterine involution. In conclusion， this study demonstrates that PNSC can regulate angiogenesis to promote uterine involution by activating the PI3K/AKT/mTOR pathway.
