Objective To compare the efficacy of using“distal acupoints only”vs.“local acupoints mainly combined with distal acupoints”in cases of acute low back pain(AlBP).Methods A total of 102 eligible patients aged 18–65 years with AlBP lasting less than 6 weeks will be randomized in a 1:1 ratio to the distal acupoints only group(DPOG)and the local acupoints mainly combined with the distal acupoints group(lPMG).During a 4-week treatment period,patients in the DPOG will receive acupuncture at distal acupoints only(Houxi[SI 3]and Yaotongxue[EX-UE 7])twice a week,while those in the lPMG group will receive acupuncture at local acupoints(mainly Shenshu[Bl 23]and Dachangshu[Bl 25])combined with distal points(Weizhong[Bl 40]).The patients in both groups will be evaluated at every session of treatment,and the follow-up will be performed for 3 *** primary outcome measure will be the change in AlBP intensity,assessed using visual.analogue scale scores before and after *** secondary outcome measure will be the evaluation of functional disability using the Oswestry Disability *** This study compares the DPOG and lPMG to explore the feasibility of the DPOG in the treatment of AlBP.

Human fallopian tubes (FTs) play important roles in the whole reproductive process. FTs are the site for the final maturation of gametes, fertilization, transport of preimplantation embryos, and early embryonic development before entering the uterus. All these functions are critical in the establishment of a successful pregnancy. When the embryo is in transit through the FT, the FT microenvironment changes through endocrine, paracrine, autocrine, and juxtacrine mechanisms which involve various hormones and bioactive substances mainly from the neighboring cells. Therefore, the interactions between the embryo and the FT may be the earliest embryo-maternal communications that are essential for the establishment of pregnancy. This review critically discusses the evidence of various hormonal.and bioactive mediated control of the microenvironment in the FTs during the earliest embryo-maternal communications. Moreover, we highlight existing gaps in the knowledge and the importance of exploring more of the physiology of FTs which will hold the key to producing high-quality embryos for patients seekingin vitro fertilization (IVF) treatments.

Successful implantation requires concerted interactions during the apposition, adhesion, and invasion of the embryo into a receptive endometrium. However, the embryo implantation rate for assisted reproduction remains low despite the transfer of good quality embryos. Changes in endometrial transcriptomics, proteomics, lipidomics, and even microbiota all play important roles in embryo implantation. Specifically, the expression of steroid hormone-regulated adhesive and anti-adhesive molecules during the embryo implantation window is becoming an area of increasingly intense research. This review (a) summarizes the different molecules expressed in the receptive endometrium and (b) proposes the use of surface protein markers to predict pregnancy outcomes from assisted reproduction.

目的研究不同年龄功能性语音障碍儿童(speech sound disorders,SSD)的语音障碍严重程度是否存在区别,并探讨其辅音语音错误特征。方法以2019年7月~2022年11月于中南大学湘雅三医院康复医学科就诊的172例SSD患儿为研究对象,其中4岁97例(男63例,女34例),5岁45例(男36例,女9例),6岁30例(男22例,女8例)。以图片命名法对单词水平进行语音评估,记录辅音的语音错误类型,并计算辅音正确百分比(percentage consonants correct,PCC)和不同构音方式辅音(塞音化、塞擦音化、摩擦音化、鼻音化以及边音化)的错误比例。结果①三组间PCC差异无统计学意义(P>0.05);②三组间省略错误存在显著差异(Z=6.531,P=0.0380.05);③三组儿童省略错误中均以边音/l/省略为主;④三组儿童均存在较多的塞音化、塞擦音化和摩擦音化,但三组不同构音方式(塞音化、鼻音化、塞擦音化、摩擦音化和边音化)的辅音错误占比无差异(P>0.05)。结论不同年龄SSD儿童的语音障碍严重程度无明显差别,但省略错误分布存在明显差异,构音方式存在相似的语音错误特征。
