ObjectiveTo investigate the mechanism of action of modified Shaofu Zhuyutang in antagonizing cellular pyroptosis and fibrosis in ectopic endometrial tissues of endometriosis through the Toll-like receptor 4/nuclear factor-κB/NOD-like receptor protein 3 （TRL4/NF-κB/NLPR3） signaling pathway. MethodsSeventy-two SPF-grade female SD rats were randomly divided into a sham-operated group （n = 12） and a modeling group （n = 60）. The rats in the sham-operated group underwent a caesarean section， while the rats in the modeling group were used to establish an endometriosis model through the auto-transplantation method. After successful modeling， the animals were randomly divided into the model group， progesterone group （0.25 mg·kg^-1）， and modified Shaofu Zhuyutang low-， medium-， and high-dose groups （7.5， 15， 30 g·kg^-1）， with 12 animals in each group. After 4 weeks of drug administration， voluntary activity and heat pain latency were observed. The rats were sacrificed for tissue collection， and Masson staining were used to observe histopathological changes in the endometrial tissues. Enzyme-linked immunosorbent assay （ELISA） was used to measure serum levels of interleukin-18 （IL-18）， interleukin-1β （IL-1β）， tumor necrosis factor-α （TNF-α）， and transforming growth factor-β （TGF-β）. Immunohistochemistry （IHC） was used to detect the protein expression area of tumor necrosis factor-related factor 6 （TRAF6） and NLPR3 in the endometrial tissues. Immunofluorescence （IF） was used to detect the relative fluorescence intensity of Caspase-1 and gasdermin D （GSDMD） in the endometrial tissues. Western blot was employed to measure the relative expression of TRL4， myeloid differentiation factor 88 （MyD88）， TRAF6， NF-κB p65， phosphorylated NF-κB p65 （p-NF-κB p65）， and NLPR3 proteins in endometrial tissues. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression of TRL4， MyD88， TRAF6， NF-κB， and NLPR3 in the endometrial tissues. ResultsCompared with the sham-operated group， rats in the model group showed reduced voluntary activity and shorter heat pain latency. Serum levels of IL-18， IL-1β， TNF-α， and TGF-β were elevated. The relative expression areas of TRAF6 and NLPR3 proteins were increased， and the relative fluorescence intensity of Caspase-1 and GSDMD was enhanced. The relative expression of TRL4， MyD88， TRAF6， NF-κB p65， p-NF-κB p65， and NLPR3 proteins， along with the expression of TRL4， MyD88， TRAF6， NF-κB， and NLPR3 mRNA， were significantly increased （P<0.01）. Compared with the model group， rats in the progesterone group and the modified Shaofu Zhuyutang medium- and high-dose groups exhibited improved voluntary activity， longer heat pain latency， the fibrosis of endometrial tissue is alleviated. Serum levels of IL-18， IL-1β， TNF-α， and TGF-β were decreased. The relative expression areas of TRAF6 and NLPR3 proteins decreased， and the relative fluorescence intensity of Caspase-1 and GSDMD weakened. The relative expression of TRL4， MyD88， TRAF6， p-NF-κB p65， NLPR3 proteins， and TRL4， MyD88， TRAF6， NF-κB， and NLPR3 mRNA expression were reduced （P<0.05， P<0.01）. ConclusionModified Shaofu Zhuyutang may play a therapeutic role in endometriosis by interfering with key proteins in the TRL4/NF-κB/NLPR3 signaling pathway， reducing NLRP3 inflammasome-induced cellular pyroptosis， antagonizing the fibrosis process in ectopic endometrial tissues， improving the inflammatory microenvironment in the pelvic cavity， and alleviating pain.

Objective:To explore the value of chromosomal microarray analysis (CMA) in the genetic diagnosis of different types of fetal growth restriction (FGR).Methods:A retrospective analysis was conducted on 120 cases who were diagnosed with FGR by ultrasound and underwent prenatal diagnosis at the Department of Obstetrics & Gynecology and Reproductive Medicine, Peking University First Hospital, from January 2016 to December 2021. The cases were divided into three groups based on the gestational age at the first diagnosis:<28 weeks (40 cases), 28-31 +6 weeks (65 cases), and ≥32 weeks (15 cases). They were also categorized into isolated and non-isolated FGR based on the presence of other ultrasound abnormalities (69 and 51 cases in each). Chromosomal karyotype analysis and CMA were conducted on all patients. The prenatal diagnosis results were analyzed, as well as the detection of chromosomal abnormalities in different gestational age groups and types of FGR. Statistical analysis was performed using Fisher's exact test. Results:(1) A total of 14 abnormalities were detected by CMA and four cases were detected by chromosomal karyotype analysis. The abnormal detection rate of CMA was higher than that of chromosomal karyotype analysis [11.7% (14/120) vs. 3.3% (4/120), P=0.025]. Among the total 14 cases of chromosomal abnormalities, there were seven pathogenic copy number variations (CNVs) and four variants of unknown significance (VUS), as well as two cases of trisomy-18 and one case of Turner syndrome. Among the 14 cases, eight had associated ultrasound abnormalities. Eleven of the 14 cases opted for induced abortion; three continued pregnancy to delivery, with two neonates showing no abnormalities and one exhibiting slightly delayed physical development. Both methods detected three cases of aneuploidy mnumber abnormalities (2.5%, 3/120) For chromosomal abnormalities <10 Mb, the detection rate of CMA was higher than that of chromosomal karyotype analysis [9.2% (11/120) vs. 0.8% (1/120), Fisher's exact, P=0.005]. Both methods detected one case of <10 Mb CNV, while CMA alone detected ten cases of <10 Mb microdeletions/microduplications (8.3%, 10/120), including six cases of pathogenic CNVs and four cases of VUS. (2) Among the 40 cases in the <28 weeks group, six cases (15.0%) of chromosomal abnormalities were detected, including three cases of aneuploidy, two cases of pathogenic CNVs, and one case of VUS. Among the 65 cases in the 28-31 +6 weeks group, seven cases (10.8%) of chromosomal abnormalities were detected, including five cases of pathogenic CNVs and two cases of VUS. Of the 15 cases in the ≥32 weeks group, one case of chromosomal abnormality was detected, which was VUS. (3) No statistically significant difference was found in the detection rate of chromosomal abnormalities between the isolated FGR and the non-isolated FGR groups [8.7%(6/69) vs. 15.7%(8/51), Fisher's exact, P=0.263]. (4) After excluding the ≥32 weeks non-isolated FGR group (only one case), the <28 weeks non-isolated FGR group had the highest detection rate of chromosomal abnormalities (1/18), while no abnormalities were detected in the ≥32 weeks isolated FGR group. Conclusions:Among FGR fetuses, the highest detection rates of chromosomal abnormalities are found in early-onset and non-isolated FGR. Prenatal diagnosis with CMA testing can significantly improve the detection rate of genetic causes in various types of FGR fetuses.

Global developmental delay/intellectual disability (GDD/ID) is an enormous group of neurodevelopmental disorders with diverse clinical and genetic heterogeneity. The estimated prevalence of GDD/ID was 1%-3%, affecting about 150 million people. GDD/ID is one of the leading causes of disability in children worldwide. The causes of GDD/ID are complex, comprising genetic and environmental factors. It is often co-morbid with a variety of psychiatric behavioral disorders, such as autism spectrum disorder and attention deficit hyperactivity disorder. Owing to the improvement of genetic technology, monogenic GDD/ID has been one of the hot-spot research in genomic era, and the relevant preventive measures deserve extensive attention. In this review, we summarized the advances in genetics and prevention of monogenic GDD/ID.

Background The operation mode of automobile manufacturing industry (AMI) makes workers have different degrees of occupational stress and burnout, which may lead to negative emotions and depressive symptoms. Objective To study the relationship between occupational stress, job burnout, and depressive symptoms in AMI workers. Methods In this study, 1300 workers from a Guangzhou AMI company were selected as subjects by cluster random sampling method. Occupational stress, job burnout, and depressive symptoms of the workers were assessed by using the Effort-Reward Imbalance (ERI) questionnaire, the Maslach Burnout Inventory general survey questionnaire, and the Patient Health Questionnaire-9, respectively. Hierarchical regression was used to analyze the effects of occupational stress and job burnout on depressive symptoms in AMI workers. Mediating effect model was used to analyze the mediating effect of job burnout on the relationship between occupational stress and depressive symptoms. Results There were 1300 questionnaires distributed, 1228 valid questionnaires collected, with a 94.5% recovery rate. The ERI ratio of 1228 AMI workers was 1.06±0.72, and the positive rate of occupational stress was 37.3% (458/1228). The score of job burnout was 2.18±1.37, and the positive rate of job burnout was 62.6% (769/1228). The score of depressive symptoms was 10.27±6.42, and the positive rate of depressive symptoms was 47.1% (578/1228). The dimensional scores of effort and over-commitment in occupational stress as well as emotional exhaustion and depersonalization in job burnout of AMI workers were positively correlated with the depressive symptom scores (r_s=0.415, 0.571, 0.573, 0.593, P＜0.05). The dimensional scores of reward and personal achievement were negatively correlated (r_s=−0.454, −0.339, P＜0.05). The percentages of variance in depressive symptoms score explained by occupational stress and job burnout were 26.7% and 16.6%, respectively. Job burnout had a partial mediating effect between the three dimensions of occupational stress and depressive symptoms, and the mediating effect values were −0.2832 (95%CI: −0.3250– −0.2434), 0.3553 (95%CI: 0.3071–0.4041), and 0.4193 (95%CI: 0.3681–0.4725), respectively. Conclusion AMI workers' occupational stress affects job burnout, but also indirectly affects depressive symptoms. Job burnout partially mediates the association between occupational stress and depressive symptoms. Reducing occupational stress and burnout levels of AMI workers may alleviate depressive symptoms.
