To explore the mechanism through which moxibustion promotes endometrial repair in rats with in thin endometrium (TE). Female SD rats were randomized into control group, 95% anhydrous ethanol-induced TE model group and moxibustion (at "Guan Yuan") group. High-throughput sequencing was used to identify the target genes of TE, and the targeting relationship between miR-223-3p and NLRP3 was verified using a dual luciferase assay. Histopathological of rat uterus was observed with HE staining, and expressions of miR-223-3p and NLRP3 were detected using RT-qPCR; serum levels of IL-1β and IL-18 of the rats were detected using ELISA, and protein expressions of NLRP3, ASC, caspase-1 and GSDMD in the uterus were detected with Western blotting. The pregnancies of the rats after treatment were counted. Enrichment analysis of the differential genes suggested up-regulated inflammatory response in TE, and dual luciferase assay verified targeted inhibition of NLRP3 expression by miR-223-3p. The rat models of TE had significantly decreased endometrial thickness and reduced endometrial glands and blood vessels with enhanced mRNA expression of NLRP3, increased serum levels of IL-1β and IL-18, up-regulated protein expressions of NLRP3, ASC, caspase-1 and GSDMD, lowered pregnancy rates on both the affected and unaffected sides and the overall number of pregnancies. Treatment of the rat models with mo-xibustion obviously increased the endometrial thickness and the density of glands and blood vessels, up-regulated miR-223-3p expression, lowered serum IL-1β and IL-18 levels and the protein expressions of NLRP3, ASC, caspase-1 and GSDMD, and significantly increased the number of pregnancies. Moxibustion at "Guan Yuan" acupoint up-regulates the expression of miR-223-3p, which results in targeted inhibition of NLRP3 to suppress pyroptosis and promote endometrial repair in rat models of TE.

BACKGROUND:Endometriosis (EMS), a well-recognized chronic inflammatory disorder, characterized by significant immune dysregulation, in which myeloid-derived suppressor cells (MDSCs) are essential for facilitating immunosuppression and driving to disease progression. Cryptotanshinone (CTS) is an active compound capable of modulating MDSC-mediated immunosuppression; however, its therapeutic effects and mechanisms in the treatment of EMS remain unclear. PURPOSE:This study aims to investigate the therapeutic potential of CTS in modulating MDSCs through JAK2/STAT3 signaling pathway and to evaluate its effects on immune microenvironment and endometriotic lesion growth in EMS. METHODS:Transcriptomic data (GSE141549) and single-cell RNA sequencing data (GSE213216) were analyzed to compare immune cell populations in control endometrium (CE), eutopic endometrium (EuE) and ectopic endometrium (EcE) of patients with EMS. Network pharmacology analysis, surface plasmon resonance (SPR) and cellular thermal shift assay (CETSA) were utilized to explore the molecular mechanism of CTS's effects on MDSCs. A C57BL/6J EMS mice model was established to evaluate CTS's influence on MDSC-mediated immune response in vivo. Flow cytometry and immunofluorescence were used to analyze the immune cell populations, particularly MDSCs and CD8+ T cells. Ex vivo bone marrow (BM)-derived MDSCs were prepared to investigate the modulatory activities of CTS on the frequency and function of MDSCs. The impacts of CTS on JAK2/STAT3 pathway were further examined by western blot. RESULTS:Bioinformatic analysis revealed that, among the three progression stages (CE, EuE, and EcE), the EcE stage exhibited a relatively elevated level of MDSCs and a reduced level of CD8+ T cells. Network pharmacological analysis, along with SPR and CETSA identified that CTS potentially modulates MDSCs in EMS by targeting the JAK2/STAT3 pathway. In vivo studies demonstrated that a relatively high dose of CTS treatment (60mg/kg) effectively inhibited lesion growth, reduced the population of MDSCs, and enhanced CD8+ T cell infiltration. Ex vivo experiments showed that CTS decreased the BM-derived MDSC frequency and rescued the suppressive ability of MDSC upon CD8+ T cells in a dose-dependent manner. Further mechanism analysis confirmed that CTS modulates the expression of immunosuppressive genes and proteins associated with MDSCs through JAK2/STAT3 pathway. CONCLUSION:This study is the first to demonstrate that CTS is a promising natural compound for EMS treatment by inhibiting MDSC accumulation and modulating MDSC-mediated immune responses. Its therapeutic efficacy is linked to the modulation of the JAK2/STAT3 signaling pathway.

Endometrium plays a key role in embryo implantation and maintenance of pregnancy. However, to repair endometrial injury is still a challenge. In recent years, hydrogel materials have been widely used as effective support matrices to prevent intrauterine adhesions after endometrial injury. They can also be used as preparation scaffolds for encapsulating MSCs and certain therapeutic drugs. This study aimed to develop a preparation scaffold with high tissue affinity, high viscoelasticity and controlled release for repair of endometrial injury. The scaffold utilized heparin poloxamer (HP) as the matrix material and ε-polylysine (EPL) as the functional excipient to prepare a hydrogel that is suitable for endometrial adhesion and further encapsulate BMSCs. Furthermore, a strategy of the thermo-sensitive EPL-HP hydrogel-encapsulated BMSCs were used for better homing of BMSC after transplantation into the rat endometrial injury model, so as to exert the potential of endometrial regeneration by activating Nrf2 to regulate SDF-1/CXCR4 axis.

ObjectivesThe objective of this study was to investigate the glycolytic activity of adenomyosis, which is characterized by malignant biological behaviors including abnormal cell proliferation, migration, invasion, cell regulation, and epithelial-mesenchymal transition.MethodsFrom January 2021 to August 2022, a total of 15 patients who underwent total hysterectomy for adenomyosis and 14 patients who had non-endometrial diseases, specifically with cervical squamous intraepithelial neoplasia and uterine myoma, were included in this study. Myometrium with ectopic endometrium from patients with adenomyosis while normal myometrium from patients in the control group were collected. All samples were confirmed by a histopathological examination. The samples were analyzed by liquid chromatography-mass spectrometry (LC-MS), real-time quantitative PCR, NAD+/NADH assay kit as well as the glucose and lactate assay kits.ResultsEndometrial stroma and glands could be observed within the myometrium of patients in the adenomyosis group. We found that the mRNA expressions of HK1, PFKFB3, glyceraldehyde-3-phospate dehydrogenase (GAPDH), PKM2, and PDHA as well as the protein expressions of PFKFB3 were elevated in ectopic endometrial tissues of the adenomyosis group as compared to normal myometrium of the control group. The level of fructose 1,6-diphosphate was increased while NAD + and NAD+/NADH ratio were decreased compared with the control group. Besides, increased glucose consumption and lactate production were observed in myometrium with ectopic endometrium.ConclusionsWe concluded that altered glycolytic phenotype of the myometrium with ectopic endometrium in women with adenomyosis may contribute the development of adenomyosis.

OBJECTIVE To evaluate the effectiveness of electroacupuncture (EA) for female stress urinary incontinence (SUI). METHODS We searched 12 databases electronically from inception to November 2018 without language restrictions. We included randomized controlled trials (RCTs) involving women with SUI, but excludd other types of urinary incontinence or studies that were not RCTs. Two independent reviewers extracted study characteristics, with disagreements resolved by consensus. Data were pooled and expressed as mean difference (MD) for continuous outcomes and relative risk (RR) for dichotomous outcomes, with 95% confidence intervals (CI). This study was registered with the International Prospective Register of Systematic Reviews (number CRD42018089734). RESULTS We found very low to high level evidence that EA improved the effective rate (RR = 2.03, 95%CI: 1.40, 2.95; P = 0.0002) and reduced urine leakage as measured by the 1-hour pad test (MD = 3.33, 95%CI: 0.89, 5.77; P = 0.008), International Consultation on Incontinence Questionnaire Short Form score (MD = 3.14, 95%CI: 2.42, 3.85; P < 0.00001), and 72-hour incontinence episodes (MD = 1.17, 95%CI: 0.56, 1.78; P = 0.0002) compared with sham electroacupuncture (SA), pelvic floor muscle training, and medication. CONCLUSION The effectiveness and safety of EA for key outcomes for women with SUI are statistically significantly better than those of SA, but most available evidence is very low or low quality. More well-designed RCTs are needed to confirm these findings.

目的 探讨差速贴壁法获取人子宫腺肌病病灶细胞的平滑肌细胞的纯化时间.方法 采取组织块酶消化法进行子宫腺肌病病灶细胞原代培养,待生长融合80％～90％时根据细胞贴壁时间分为未处理组及15 min、30 min、60 min、90 min四个时间组,各时间贴壁组与未贴壁组进行细胞筛选与培养,以免疫组化方法鉴定平滑肌细胞及其纯度.结果 400倍镜视野下每组16个视野计数算滑肌细胞数百分比,未处理组最低,为12.60％;未贴壁15 min组最高,为73.38％,与未处理组比较有统计学差异(P<0.01);贴壁90 min组与未处理组比较无统计学差异(P>0.05).结论 用差速贴壁法分离人子宫腺肌病病灶的平滑肌细胞可通过贴壁15 min剔除大部分杂质细胞,选择15 min内未贴壁细胞继续培养传代可进一步获取纯度更高的子宫平滑肌细胞.
