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.

Background Anxiety and depression are common perinatal mental health issues that often occur together and can have serious negative effects on both maternal and infant health. Objective To examine the relationships between lifestyle factors and comorbid anxiety and depression (CAD) among pregnant women in Shanghai. Methods The study estimated the prevalence of CAD during the first, second, and third trimesters of pregnancy using the Self-rating Anxiety Scale (SAS) and Center for Epidemiological Studies-Depression (CES-D) based on data from the China National Birth Cohort (CNBC) embryonic-derived diseases with assisted reproductive technology (ART) sub-cohort. Information on demographics, sleep status, nutritional intake, and exercise during each trimester was collected through self-made questionnaires, the Pittsburgh Sleep Quality Index (PSQI), and the Food Frequency Questionnaire (FFQ). Lifestyle factors (such as sleep status, nutritional intake, and exercise during each trimester) were analyzed using logistic regression and generalized linear mixed models (GLMM) to determine their impacts on the prevalence of CAD (yes or no) among pregnant women. Results A total of 2876 pregnant women were included in this study. The prevalence of CAD was 10.6% (305), 3.6% (103), and 5.5% (159) in the first, second, and third trimesters of pregnancy, respectively. The logistic regression analysis revealed that poor sleep quality throughout the entire pregnancy were statistically associated with an increased prevalence of CAD, and the odds ratios (OR) with 95% confidence intervals (CI) were 2.817 (1.845, 4.301), 2.840 (1.855, 4.347), and 9.316 (5.835, 14.876) for the first, second, and third trimesters, respectively, when compared to good sleep quality. Additionally, compared to an intake frequency of 7 times per week, the frequency of egg intake ≤3 times per week in the first trimester (OR=2.025, 95%CI: 1.197, 3.425) and the frequency of egg intake of 4–6 times per week (OR=1.896, 95%CI: 1.117, 3.216) or ≤3 times per week (OR=1.906, 95%CI: 1.082, 3.357) in the third trimester were associated with an increased risk of CAD (P<0.05). Moreover, when compared to a frequency of exercise >3 times per week, never or almost never exercising in the second trimester (OR=2.218, 95%CI: 1.220, 4.035) was associated with an increased risk of CAD (P<0.05). The GLMM analysis also demonstrated a significant association between poor sleep quality, lower exercise frequency, or lower intake frequency of vegetables, eggs, or milk and an increased risk of CAD (P<0.05). Conclusion The prevalence of CAD among pregnant women in Shanghai follows a U-shaped distribution, with the highest rate occurring in early pregnancy and the lowest rate in mid-pregnancy. Factors such as poor sleep quality, inadequate intake of vegetables, eggs, or milk, and lack of exercise during pregnancy may increase the risk of CAD. Implementing lifestyle interventions during pregnancy could potentially reduce the risk of mental health problems and improve the overall health of both mothers and babies.

The diagnosis of Parkinson's disease(PD)mainly relies on clinical appearance of patients,and the routine magnetic resonance scan has difficulty in finding the abnormality of that,which is not able to meet the requirement of early and precise quantification for the PD lesion area.Diffusion magnetic resonance imaging(dMRI)technique is a noninvasive method of examining the microstructure of living tissue.Diffusion weighted imaging(DWI)and diffusion tensor imaging(DTI)were the most widely used in clinical practice.However,the principles of them have limitation,which are not able to fully outline the microstructure of brain tissue.This paper discussed several new dMRI techniques that are able to make up conventional dMRI model,which included diffusion kurtosis imaging(DKI),neurite orientation dispersion and density imaging(NODDI)and diffusion tensor imaging index of perivascular space(DTI-ALPS).Moreover,this paper summarized the applications of above imaging technique in exploring the changes of the microstructure of brain tissue of PD patients,so as to provide more imaging information for the pathological changes of PD patients.

The "Developmental Origins of Health and Disease, DOHaD" theory suggests that adverse factors in early life can lead to the occurrence of chronic diseases in adulthood. In recent years, it has been discovered that maternal factors, intrauterine development environment and environmental exposure during pregnancy can mediate the changes of early egg/embryo development, promote the occurrence of reproductive disorders such as polycystic ovary syndrome, diminished ovarian reserve, and endometriosis, and induce intergenerational genetic effects. This article has reviewed the progress of research on maternal factors which may affect the pathogenesis of reproductive disorders, and expounds its mechanism from the perspectives of epigenetic mechanisms such as DNA methylation, histone modification and non-coding small RNA (miRNA) modification, with an aim to provide insights for studying the occurrence of adult reproductive disorders in early life and before pregnancy.

AIM:To investigate the interaction mechanisms of estrogen receptor β(ERβ),nuclear factor-κB(NF-κB)and activator protein-1(AP-1)in colorectal cancer by analyzing the transcriptome data after tumor necrosis fac-tor α(TNF-α)treatment and combining it with NF-κB/p65 and ERβ cistrome data in colon cancer cell lines HT29 and SW480.METHODS:The TNF-α transcriptome was integrated with p65 and ERβ cistrome data.Protein interaction net-works of TNF-α,NF-κB/p65 and ERβ were constructed in colon cancer cell lines HT29 and SW480 using R.RE-SULTS:TNF-α regulated genes through p65 DNA binding,which were mainly enriched in the NF-κB and mitogen-acti-vated protein kinase(MAPK)pathways.Components of the NF-κB/p65 and MAPK pathways had potential interactions with AP-1 family proteins.ERβ overexpression did not significantly affect TNF-α-mediated gene regulation but may regu-late AP-1 activity through the MAPK and phosphatidylinositol 3-kinase(PI3K)/Akt pathways.Furthermore,ERβ de-creased p65 DNA binding sites in HT29 but increased p65 binding sites in SW480,suggesting cell line-specific regulation of NF-κB by ERβ.CONCLUSION:In colorectal cancer,NF-κB,ERβ and AP-1 have potential interactions:TNF-α can regulate AP-1 through NF-κB,while ERβ overexpression can alter NF-κB-mediated regulation,and the influence of ERβ on NF-κB may be gender-related.

ObjectiveTo investigate the effect and mechanism of Nongsuo Dangguiwan in improving ovarian oxidative stress in rats with ovarian dysfunction. MethodThirty-six adult female SD rats were randomly divided into normal group， model group， positive drug group （Femoston， 0.3 mg·kg^-1）， and high-， medium-， and low-dose groups of concentrated Nongsuo Dangguiwan （2.08， 4.16， 8.32 g·kg^-1）， with six rats in each group. Rats， except for those in the normal group， were injected with 80 mg·kg^-1 vinyl cyclohexene dioxide （VCD） per day for 14 consecutive days to induce ovarian dysfunction. From the 15th day， rats were treated with corresponding drugs by gavage， while those in the model group received 2 mL·kg^-1 saline， once daily for 28 consecutive days. The ovarian index， levels of related hormones including estradiol （E₂）， follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， and anti-mullerian hormone （AMH） in serum， as well as superoxide dismutase （SOD） activity and glutathione （GSH） content in serum were measured by enzyme-linked immunosorbent assay （ELISA）. The malondialdehyde （MDA） content in serum was detected by the thiobarbituric acid （TAB） method. Ovarian morphology was observed by hematoxylin-eosin （HE） staining. The expression of nuclear factor E₂-related factor 2 （Nrf2）， heme oxygenase-1 （HO-1）， SOD2， and SOD1 in ovarian tissues was detected by immunohistochemistry （IHC） and Western blot. ResultCompared with the normal group， the model group showed a significant reduction in growing follicles in the ovary， loose arrangement of granulosa cells in the follicle， decreased body weight， ovarian index， and serum AMH and E₂ levels， increased LH and FSH levels （P<0.01）， reduced levels of SOD and GSH in serum （P<0.01）， and increased MDA level （P<0.01）. Compared with the model group， the groups with drug intervention showed increased ovarian index （P<0.05， P<0.01）， increased serum E₂ level （P<0.05， P<0.01）， decreased FSH， AMH， and LH levels （P<0.05， P<0.01）， increased number of growing follicles in the ovary， potentiated SOD activity in serum， increased GSH content， decreased MDA content （P<0.05， P<0.01）， and up-regulated expression levels of Nrf2， HO-1， SOD2， and SOD1 proteins in ovarian tissues （P<0.05， P<0.01）. ConclusionNongsuo Dangguiwan can regulate serum hormone levels， increase the expression of Nrf2， HO-1， SOD2， and SOD1 in ovarian tissues， and improve ovarian antioxidant capacity to resist oxidative stress injury， thereby improving ovarian reserve function.

The disclosure of medical service information is an important tool to help patients make medical decisions, improve the quality of medical services, and strengthen hospital supervision.The effectiveness of disclosing medical service information lies in meeting the needs of patients.The disclosure of medical service information in foreign countries started earlier that China. In order to strengthen the compatibility between medical service information and patient needs, some developed countries had used patient experience surveys, patient satisfaction surveys, and patient medical reports as the sources of public information.These countries publicly released information on medical quality, doctor-patient feedback, and social responsibility through official unified release platforms and processes, while establishing diversified and institutionalized regulatory mechanisms to create a good information disclosure system and mechanism for patient decision-making, service quality improvement, and government regulation.By drawing on the experience of medical service information disclosure in developed countries, the author proposed that we should carry out a comprehensive survey of patient needs, establish a convenient and transparent information disclosure platform, and establish a sound scientific regulatory mechanism, so as to provide reference for promoting the establishment of a patient demand oriented medical service information disclosure mechanism in China

Whether Fanconi anemia (FA) heterozygotes are predisposed to bone marrow failure and hematologic neoplasm is a crucial but unsettled issue in cancer prevention and family consulting. We retrospectively analyzed rare possibly significant variations (PSVs) in the five most obligated FA genes, BRCA2, FANCA, FANCC, FANCD2, and FANCG, in 788 patients with aplastic anemia (AA) and hematologic malignancy. Sixty-eight variants were identified in 66 patients (8.38%). FANCA was the most frequently mutated gene (n = 29), followed by BRCA2 (n = 20). Compared with that of the ExAC East Asian dataset, the overall frequency of rare PSVs was higher in our cohort (P = 0.016). BRCA2 PSVs showed higher frequency in acute lymphocytic leukemia (P = 0.038), and FANCA PSVs were significantly enriched in AA and AML subgroups (P = 0.020; P = 0.008). FA-PSV-positive MDS/AML patients had a higher tumor mutation burden, higher rate of cytogenetic abnormalities, less epigenetic regulation, and fewer spliceosome gene mutations than those of FA-PSV-negative MDS/AML patients (P = 0.024, P = 0.029, P = 0.024, and P = 0.013). The overall PSV enrichment in our cohort suggests that heterozygous mutations of FA genes contribute to hematopoietic failure and leukemogenesis.
