Endometriosis (EMT) is a common disease with frequent occurrence and difficult to be cured in modern clinical practice of obstetrics and gynaecology. It is characterized by progressively worsening dysmenorrhoea, pelvic mass, and infertility. The incidence of EMT is growing and increasingly younger patients are diagnosed with this disease, which poses a serious threat to the reproductive and psychological health of women of childbearing age and adolescent females. However, the pathogenesis of EMT is still not completely clear, and the disease has a long course. Therefore, developing new therapies is an urgent clinical problem to be solved. Great progress has been achieved in the treatment of EMT with traditional Chinese medicine (TCM), while the underlying mechanism remains in exploration. Programmed cell death (PCD) is a cell death mode mediated by a variety of bio-molecules with specific signaling cascades. The known PCD processes include apoptosis, pyroptosis, autophagy, ferroptosis, and cuproptosis, which all play a pivotal role in the development of EMT. Researchers have made achievements in the treatment of EMT with TCM, which regulates PCD via multiple pathways, routes, targets, and mechanisms. However, the progress in the regulation of PCD in the treatment of EMT with TCM remains to be reviewed. This paper reviews the research progress in the treatment of EMT with TCM from five PCD processes (apoptosis, pyroptosis, autophagy, ferroptosis, and cuproptosis), with the aim of providing a theoretical basis for the clinical prevention and treatment of EMT.

ObjectiveTo explore the possible mechanisms of Wenyang Huazhuo Formula (温阳化浊方, WHF) in improving reproductive aging from the perspective of the ovarian mechanical microenvironment. MethodsThe experiment included five groups, 3-month group (20 female mice at 3 months of age), 6-month group (20 female mice at 6 months of age), 6-month + WHF group (20 female mice at 5 months of age treated with WHF), 9-month group (20 female mice at 9 months of age), and 9-month + WHF group (20 female mice at 8 months of age treated with WHF). The 6-month + WHF group and 9-month + WHF group were orally administered WHF 41.2 g/(kg·d) once daily for 4 consecutive weeks. The other three groups received no intervention. Reproductive hormone levels were measured by ELISA. HE staining was used to count the numbers of various stages of follicles. Ovarian hyaluronic acid (HA) content and collagen fiber content were measured to evaluate the ovarian mechanical microenvironment. Superovulation was performed to observe the number of eggs obtained, as well as the number of offspring and birth weight to assess fertility. The in vitro fertilization and blastocyst culture of oocytes from female offspring in each group were observed to evaluate the effect of WHF on offspring reproductive potential. ResultsCompared with the 3-month group, the 6-month group and 9-month group showed significantly decreased serum levels of gonadotropin-releasing hormone (GnRH), follicle-stimulating hormone (FSH), and luteinizing hormone (LH), decreased ovarian collagen content, and reduced numbers of primordial and secondary follicles. In contrast, the numbers of primary follicles, antral follicles, and atretic follicles increased. The levels of anti-Müllerian hormone (AMH), ovarian HA content, and the fertilization rate, cleavage rate, and blastocyst formation rate of oocytes from offspring were significantly lower (P<0.05). Compared with the 6-month group, the 6-month + WHF group showed significantly reduced serum levels of GnRH, FSH, and LH, with a significant decrease in primary follicles, antral follicles, and atretic follicles as well as increase of AMH levels, ovarian HA content, number of primordial and secondary follicle, egg count, and offspring birth weight (P<0.05). Compared with the 9-month group, the 9-month + WHF group exhibited reduced GnRH, FSH, and collagen fiber content, as well as reduced number of primary follicles, antral follicles, and atretic follicles. However, AMH levels, ovarian HA content, number of primordial and secondary follicle, egg count, offspring numbers, birth weight, fertilization rate, cleavage rate, and blastocyst formation rate of oocytes from offspring all significantly increased (P<0.05). ConclusionWHF can significantly improve the ovarian reserve, fertility, and reproductive potential in offspring during reproductive mid-life and late-life stages. Its effect may be related to the remodeling of the mechanical microenvironment of aging ovaries. Moreover, the effect on the mechanical microenvironment remodeling of late-stage ovaries and the improvement of the offspring reproductive potential is more significant.

Objective:
To analyze the drug resistance of multidrug-resistant organism (MDRO) among hospitalized children in a children's hospital in Hebei Province from 2019 to 2023, so as to provide the basis for the rational clinical application of antibacterial drugs.
Methods:
Specimens including sputum, blood, urine, pus, bronchoalveolar lavage fluid, secretions, pleural fluid, and peritoneal fluid of hospitalized children from January 2019 to December 2023 were collected. Pathogen identification and drug susceptibility tests were performed on methicillin-resistant Staphylococcus aureus (MRSA), extended-spectrum β-lactamase-producing Escherichia coli (ESBLs-EC), extended-spectrum β-lactamase-producing Klebsiella pneumoniae (ESBLs-KP), carbapenem-resistant Klebsiella pneumoniae (CRKP), carbapenem-resistant Acinetobacter baumannii (CRAB), carbapenem-resistant Pseudomonas aeruginosa (CRPA) and carbapenem-resistant Escherichia coli (CREC). The department distribution, specimen distribution, and drug resistance of MDROs were analyzed.
Results:
A total of 279 086 samples were submitted for testing, with 3 512 MDROs detected. Among these, MRSA and ESBLs-EC had relatively high detection rates of 35.76% and 41.50%, respectively. In the internal medicine pediatric patients, 1 869 MDROs were detected, accounting for 53.22%. The main departments were respiratory medicine, neonatology, and intensive care. In the surgical department, 1 643 MDROs were detected, accounting for 46.78%, with the main sources being general surgery and cardiac surgery. The highest numbers of MDROs were detected in sputum, pus, and urine samples, with 1 372, 527, and 494 isolates, representing 39.07%, 15.01%, and 14.07%, respectively. The resistance rates of MRSA to penicillin, oxacillin, and erythromycin were between 81.76% and 100.00%. ESBLs-EC and ESBLs-KP had a resistance rate of 100.00% to ceftriaxone. CRKP had a resistance rate of 100.00% to ampicillin/sulbactam and imipenem. CRAB had a resistance rate of 100.00% to cefoxitin, imipenem, and meropenem. CRPA had a resistance rate of 100.00% to ampicillin/sulbactam, ceftriaxone, cefoxitin, and imipenem. CREC had a resistance rate of 100.00% to imipenem.
Conclusions
In a children's hospital in Hebei Province, infections with MDROs among hospitalized pediatric patients are primarily caused by MRSA and ESBLs-EC. These infections are mainly distributed in the departments of respiratory medicine, neonatology, intensive care, general surgery, and cardiac surgery, with the highest detection rates in sputum, pus, and urine samples. Additionally, MRSA, ESBLs-EC, ESBLs-KP, CRKP, CRAB, CRPA, and CREC show high resistance rate to most antimicrobial agents.

This study investigated the characteristics of gut microbiota imbalance in patients with infectious diarrhea caused by various pathogenic infections,and the role of Bacteroides in maintaining homeostasis in the intestinal environment.The gut microbiota in patients with diarrhea caused by pathogenic infections,such as viral and bacterial infections,was determined through full-length 16S rRNA amplicon sequencing.Patients with diarrhea were grouped and analyzed according to the presence of single bacterial infection,single viral infection,mixed infection,or Clostridioides difficile infection.Bacteroides had the highest absolute number and relative abundance in the gut microbiota in healthy people,whereas patients with infectious diar-rhea showed lower relative abundance of Bacteroides at each phylum/order/family/genus taxonomic level.Alpha diversity anal-ysis indicated no significant differences among groups.NMDS and PCoA indicated formation of distinct clusters in the control group compared with the different infectious diarrhea groups.The diversity of the gut microbiota was higher in the control group than the infectious diarrhea groups.Patients with infec-tious diarrhea caused by different pathogens showed differing predominant gut microbiota.Bifidobacterium predominated in the single viral infection group,Streptococcus predominated in the single bacterial infection group,and Lachnoclostridium predominated in the mixed infection group.Escherichia and Klebsiella were the major gut microbiota in the C.difficile infection group.Meanwhile,the dominant gut microbiota in the healthy population was Bacteroides.COG function prediction revealed that the healthy control group formed a distinct cluster from the different infection groups.The functions of defense mechanisms,cell wall synthesis,protein modification,cellular differentiation,and replication and recombination were signifi-cantly diminished in all infectious diarrhea groups.In general,patients with infectious diarrhea caused by different pathogens showed dysbiosis,with diminished gut microbiota diversity and the emergence of related biomarkers.Our findings indicated that Bacteroides has a key role in maintaining the homeostasis of the human intestinal environment,thus providing new ideas for the subsequent treatment of infectious diarrhea and research in other fields.

The cdc73(cell division cycle 73)gene encodes the RNA polymerase Ⅱ cofactor Cdc73 in fis-sion yeast(Schizosaccharomyces Pombe),and is involved in G2 checkpoint activation and regulates the cell cycle.However,whether Cdc73 regulates cell mitotic dynamics is unknown.In this study,fluores-cent protein labeling and live cell imaging techniques were used to investigate the effects of cdc73 deletion on sexual reproduction and the dynamics of microtubules,actin,mitochondria,and histones during mito-sis.The results showed that in sexual reproduction,cdc73 deletion resulted in a 14.23%increase in the length of ascospores and a 64.08%decrease in the number of cells producing four spores.Analysis of the live cell imaging results revealed that,in mitosis,the elongation length of microtubules in anaphase was shortened by 11.21%,and the elongation time was reduced by 17.39%;the formation and contraction rates of actin rings decreased by 33.33%and 26.09%,respectively,and the formation and contraction times were prolonged by 58.00%and 40.38%,respectively.Meanwhile,the expression levels of actin ring,mitochondrion,and histones also increased.This study revealed the cdc73 deletion inhibits spindle elongation and delays actin ring formation and contraction in mitosis,which provides some scientific basis for further exploring the involvement of Cdc73 in regulating microtubule and actin dynamics in cell divi-sion.
