ObjectiveTo evaluate the pregnancy outcomes of assisted reproductive technology （ART） in women with a history of thyroid cancer who retained fertility intentions after completing cancer treatment. MethodsA retrospective analysis was performed on 61 patients with a history of thyroid cancer who underwent in vitro fertilization/intracytoplasmic sperm microinjection and embryo transfer （IVF/ICSI-ET）. These patients were included as the case group. A total of 122 non-cancer patients who received ART during the same period were selected as the control group using 1∶2 matching based on age and oocyte retrieval time. Baseline characteristics， outcomes of the first ART cycle， and cumulative pregnancy outcomes were compared between the two groups. ResultsThere was no significant difference in the basic data， the total amount of gonadotropin （Gn） and the days of use between the case group and the control group （P>0.05）. However， the case group had significantly fewer retrieved oocytes， mature oocytes （MII）， lower fertilization and cleavage rates， and fewer transferable and high-quality embryos， as well as fewer embryos transferred during the first cycle （P < 0.05）. However， there was no significant difference in the rate of first embryo implantation and first clinical pregnancy between the two groups （P>0.05）. In the analysis of cumulative outcomes， the two groups did not show statistically significant differences in the cumulative pregnancy rate， clinical pregnancy rate per transfer cycle， the number of oocyte retrieval cycles required per live birth， the number of embryo transfer cycles required per live birth， and the number of embryos used for each live birth （P>0.05）. However， the cumulative live birth rate was significantly lower in the case group compared to the control group （P=0.005）. ConclusionAfter treatment for thyroid cancer， when ART is used to help pregnant women， the pregnancy outcome is comparable to that of women without tumors. Individualized reproductive management and timely fertility preservation strategies are recommended to optimize reproductive outcomes in this population.

ObjectiveTo observe the effects of Yangjing Zhongyutang （YJZYT） on mitochondrial biogenesis and oxidative stress damage mediated by the silent information regulator 1 （SIRT1）/peroxisome proliferator-activated receptor gamma coactivator-1alpha （PGC-1α） signaling pathway in cyclophosphamide （CTX）-induced rats with diminished ovarian reserve （DOR）， and to explore its mechanism in improving ovarian reserve function and follicular development. MethodsForty-two 8-week-old female SD rats with normal estrous cycles were randomly divided into a blank control group （n=7） and a model group （n=35）. Rats in the model group received a single intraperitoneal injection of CTX （90 mg·kg^-1） to establish the DOR model. After modeling， estrous cycles were monitored for 7 consecutive days， and model success was confirmed based on criteria for estrous cycle disruption. After successful modeling， rats were divided into groups for intervention： estradiol valerate group （0.09 mg·kg^-1）， and YJZYT high-， medium-， and low-dose groups （19.98， 9.99， 5.00 g·kg^-1）. The blank control group and model group were given an equal volume of distilled water by gavage. All groups received daily gavage once for 4 consecutive weeks. The general state， body weight， and ovarian wet weight of rats were observed and recorded， and the ovarian organ index was calculated. Enzyme-linked immunosorbent assay （ELISA） was used to measure serum levels of follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， estradiol （E₂）， anti-Müllerian hormone （AMH）， superoxide dismutase （SOD）， and glutathione peroxidase （GSH-Px）. Hematoxylin-eosin （HE） staining was performed to observe ovarian histomorphological changes and follicular development status. Immunofluorescence was used to detect reactive oxygen species （ROS） expression levels. Colorimetric assays were employed to measure adenosine triphosphate （ATP） and malondialdehyde （MDA） content in ovarian tissues. Quantitative Real-time polymerase chain reaction （Real-time PCR） was used to detect mitochondrial DNA （mtDNA） copy number and the mRNA expression levels of key genes including SIRT1， PGC-1α， nuclear respiratory factor 1 （NRF1）， and mitochondrial transcription factor A （TFAM）. Western blot was performed to detect the protein expression levels of SIRT1， PGC-1α， NRF1， and TFAM. ResultsCompared with the blank group， rats in the model group exhibited disrupted estrous cycles， obviously reduced body weight， and decreased ovarian index （P<0.05）. Ovarian histopathology revealed cortical thinning， loose structure， and a significant reduction in both primordial and growing follicles （P<0.01）. Serum FSH and LH levels were significantly elevated （P<0.01）， while E₂ and AMH levels were obviously reduced （P<0.05， P<0.01）. ATP content and mtDNA copy number decreased in ovarian tissue （P<0.01）， ROS expression increased， MDA levels rose， while SOD and GSH-Px activities obviously decreased （P<0.05， P<0.01）， mRNA and protein expression levels of SIRT1， PGC-1α， NRF1， and TFAM were obviously downregulated （P<0.05， P<0.01）. After treatment， compared with the model group， body weight and ovarian index obviously recovered in rats administered various doses of YJZYT （P<0.05）， serum E₂ and AMH levels increased， while FSH and LH levels obviously decreased （P<0.05， P<0.01）， ovarian tissue ATP content and mtDNA copy number were up-regulated， ROS and MDA levels decreased， and antioxidant enzymes SOD and GSH-Px activity obviously increased （P<0.05， P<0.01）， Gene and protein expression levels related to the SIRT1/PGC-1α /NRF1/TFAM signaling pathway were obviously up-regulated compared to the model group （P<0.05， P<0.01）， HE staining revealed that ovarian structure gradually recovered to integrity in all treatment groups， with a obviously increase in the number of primordial and growing follicles （P<0.05， P<0.01）. Granulosa cells were neatly arranged， indicating marked improvement in ovarian function. ConclusionYJZYT may improve ovarian function and follicular development in rats with diminished ovarian reserve by activating the SIRT1/PGC-1α signaling pathway， promoting mitochondrial biogenesis， enhancing mitochondrial function， and alleviating oxidative stress damage.

BACKGROUND: The use of inserted sham acupuncture as a placebo in randomized controlled trials (RCTs) is controversial, because it may produce specific effects that cause an underestimation of the effect of acupuncture treatment. OBJECTIVE: This systematic survey investigates the magnitude of insert-specific effects of sham acupuncture and whether they affect the estimation of acupuncture treatment effects. SEARCH STRATEGY: PubMed, Embase and Cochrane Central Register of Controlled Trials were searched to identify acupuncture RCTs from their inception until December 2022. INCLUSION CRITERIA: RCTs that evaluated the effects of acupuncture compared to sham acupuncture and no treatment. DATA EXTRACTION AND ANALYSIS: The total effect measured for an acupuncture treatment group in RCTs were divided into three components, including the natural history and/or regression to the mean effect (controlled for no-treatment group), the placebo effect, and the specific effect of acupuncture. The first two constituted the contextual effect of acupuncture, which is mimicked by a sham acupuncture treatment group. The proportion of acupuncture total effect size was considered to be 1. The proportion of natural history and/or regression to the mean effect (PNE) and proportional contextual effect (PCE) of included RCTs were pooled using meta-analyses with a random-effect model. The proportion of acupuncture placebo effect was the difference between PCE and PNE in RCTs with non-inserted sham acupuncture. The proportion of insert-specific effect of sham acupuncture (PIES) was obtained by subtracting the proportion of acupuncture placebo effect and PNE from PCE in RCTs with inserted sham acupuncture. The impact of PIES on the estimation of acupuncture's treatment effect was evaluated by quantifying the percentage of RCTs that the effect of outcome changed from no statistical difference to statistical difference after removing PIES in the included studies, and the impact of PIES was externally validated in other acupuncture RCTs with an inserted sham acupuncture group that were not used to calculate PIES. RESULTS: This analysis included 32 studies with 5492 patients. The overall PNE was 0.335 (95% confidence interval [CI], 0.255-0.415) and the PCE of acupuncture was 0.639 (95% CI, 0.567-0.710) of acupuncture's total effect. The proportional contribution of the placebo effect to acupuncture's total effect was 0.191, and the PIES was 0.189. When we modeled the exclusion of the insert-specific effect of sham acupuncture, the acupuncture treatment effect changed from no difference to a significant difference in 45.45% of the included RCTs, and in 40.91% of the external validated RCTs. CONCLUSION The insert-specific effect of sham acupuncture in RCTs represents 18.90% of acupuncture's total effect and significantly affects the evaluation of the acupuncture treatment effect. More than 40% of RCTs that used inserted sham acupuncture would draw different conclusions if the PIES had been controlled for. Considering the impact of the insert-specific effect of sham acupuncture, caution should be taken when using inserted sham acupuncture placebos in RCTs.

OBJECTIVE: Hepatocellular carcinoma (HCC) is sensitive to ferroptosis, a new form of programmed cell death that occurs in most tumor types. However, the mechanism through which ferroptosis modulates HCC remains unclear. This study aimed to investigate the oncogenic role and prognostic value of FANCD2 and provide novel insights into the prognostic assessment and prediction of immunotherapy. METHODS: Using clinicopathological parameters and bioinformatic techniques, we comprehensively examined the expression of FANCD2 macroscopically and microcosmically. We conducted univariate and multivariate Cox regression analyses to identify the prognostic value of FANCD2 in HCC and elucidated the detailed molecular mechanisms underlying the involvement of FANCD2 in oncogenesis by promoting iron-related death. RESULTS: FANCD2 was significantly upregulated in digestive system cancers with abundant immune infiltration. As an independent risk factor for HCC, a high FANCD2 expression level was associated with poor clinical outcomes and response to immune checkpoint blockade. Gene set enrichment analysis revealed that FANCD2 was mainly involved in the cell cycle and CYP450 metabolism. CONCLUSION To the best of our knowledge, this is the first study to comprehensively elucidate the oncogenic role of FANCD2. FANCD2 has a tumor-promoting aspect in the digestive system and acts as an independent risk factor in HCC; hence, it has recognized value for predicting tumor aggressiveness and prognosis and may be a potential biomarker for poor responsiveness to immunotherapy.

OBJECTIVE: Coronavirus disease 2019 (COVID-19) can result in fatigue and post-exertional malaise; however, whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection exacerbates lower urinary tract symptoms (LUTS) is unclear. This study investigated the association between prenatal SARS-CoV-2 infection and postpartum LUTS. METHODS: A multicenter, retrospective cohort study was conducted at two tertiary hospitals in China from November 1, 2022, to November 1, 2023. Participants were classified into infected and uninfected groups based on SARS-CoV-2 antigen results. LUTS prevalence and severity were assessed using self-reported symptoms and the Incontinence Impact Questionnaire-Short Form (IIQ-7). Pelvic floor muscle activity was measured using electromyography following the Glazer protocol. Group comparisons were performed to evaluate the association of SARS-CoV-2 infection with LUTS and electromyography parameters, with stratified analyses conducted using SPSS version 26.0. RESULTS: Among 3,652 participants (681 infected, 2,971 uninfected), no significant differences in LUTS prevalence or IIQ-7 scores were observed. However, SARS-CoV-2 infection was an independent factor influencing the electromyographic activity of the pelvic floor muscles (mean tonic contraction amplitudes), regardless of delivery mode ( P = 0.001). CONCLUSION Prenatal SARS-CoV-2 infection was not significantly associated with an increased risk of postpartum LUTS but independently altered pelvic floor muscle electromyographic activity, suggesting potential neuromuscular effects.

BackgroundThe functional changes of the default mode network （DMN） are closely related to the onset of major depressive disorders. However， the relationship between the DMN subsystem （core subsystem， dorsomedial prefrontal cortex subsystem， medial temporal lobe subsystem） and symptoms of first-episode major depressive disorder remains unclear. ObjectiveTo investigate abnormal functional connectivity between DMN subsystems and the whole brain in first-episode major depressive disorder patients during the resting-state， and to analyse the correlations between these functional connectivity patterns and clinical symptoms， so as to reveal the potential neural mechanisms from the perspective of DMN subsystem. MethodsFrom September 2020 to September 2023， a total of 64 first-episode outpatients and inpatients meeting the diagnostic criteria for major depressive disorder in the Diagnostic and Statistical Manual of Mental Disorders， fourth edition （DSM-IV） were enrolled at the Inner Mongolia Autonomous Region Mental Health Center as the study group. During the same period， 54 healthy volunteers matched for age， gender， and years of education were recruited from the community as the control group. Both groups were assessed using the Hamilton Depression Scale-24 item （HAMD-24）. Resting-state functional magnetic resonance images （rs-fMRI） of the two groups were acquired using a Siemens 3.0 T scanner， and differences in functional connectivity between DMN subsystems （core subsystem， dorsomedial prefrontal cortex subsystem， medial temporal lobe subsystem） and the whole brain were compared. The functional connectivity values of brain regions with statistically significant differences between the two groups were extracted. Spearman's rank correlation coefficient analysis was used to investigate the correlation between these functional connectivity values and HAMD-24 scores of the study group. ResultsUltimately， 46 patients and 43 controls completed the study. Compared with the control group， the study group exhibited significantly stronger functional connectivity in the following pathways： between the right superior parietal lobule （core subsystem） and right cerebellar lobule VIII （t=3.954， P<0.05， GRF-corrected）， between the right lateral temporal cortex （dorsomedial prefrontal cortex subsystem） and right cerebellar lobule VIII， right and left hippocampi， right medial， and paracingulate gyrus （t=4.595， 4.208， 5.200， 4.038， P<0.05， GRF-corrected）， and between the temporoparietal junction （dorsomedial prefrontal cortex subsystem） and left lingual gyrus and right cerebellar lobule VIII （t=3.557， 4.274， P<0.05， GRF-corrected）. Conversely， weaker functional connectivity was observed between the right inferior frontal gyrus and left gyrus rectus （t=-3.824， P<0.05， GRF-corrected）. Furthermore， within the study group， the functional connectivity values between the right lateral temporal cortex and right hippocampus， as well as between the temporoparietal junction and right cerebellar lobule VIII， were both negatively correlated with the HAMD-24 cognitive impairment factor score （r=-0.306， -0.318， P<0.05）. ConclusionIncreased functional connectivity between the DMN （specifically its core and dorsomedial prefrontal cortex subsystems） and cerebellum， partial limbic system， and lingual gyrus may be associated with the neuropathology of first-episode major depressive disorder. Furthermore， alterations in functional connectivity between the dorsomedial prefrontal cortex subsystem and both the cerebellum and hippocampus in these patients may be related to cognitive function. ［Funded by 2019 Annual Inner Mongolia Autonomous Region Natural Science Foundation Project （number， 2019MS03038）； 2023 Annual Inner Mongolia Autonomous Region Natural Science Foundation Project （number， 2023MS08028）］

Objective : To investigate the role of AdipoRon, an adiponectin receptor agonist, in treatment of carbon tetrachloride(CCl4) induced liver fibrosis mice model and the mechanisms. Methods : Forty mice were randomly divided into control group, model group, L-AdipoRon group and H-AdipoRon group, with 10 mice in each group. Hepatic fibrosis was induced by intraperitoneal injection of CCl4solution. The mice in L-and H-AdipoRon groups were given 100 mg/kg and 200 mg/kg AdipoRon by gavage, respectively. The activities of serum aspartate aminotransferase(AST) and alanine aminotransferase(ALT) were detected by biochemical method. Liver histopathological changes and fibrosis were detected by HE staining, Masson staining and Sirius scarlet stain. The protein expression levels of Collagen I, α-smooth muscle actin(α-SMA), matrix metalloproteinase 1(MMP-1) and matrix metalloproteinase inhibitor 1(TIMP-1) in mice liver were detected by Western blot. Lipid deposition in liver were detected by oil red O staining. The percentage(%) of CD68+ iNOS+ positive M1-type macrophages in the liver were detected by immunofluorescence. The expression levels of fatty acid synthetase(Fasn), stearoyl-CoA desaturase 1(Scd1), fatty acid transporter(Cd36), peroxissome proliferator activated receptor-α(Pparα) and carnitine palmitoyl transferase 1α(Cpt1α) in mice liver tissues, as well as M1 macrophage-related genes interleukin-6(IL-6) and tumor necrosis factor-α(TNF-α) and M2 macrophage-related genes arginase 1(Arg1), Chil3 chitinase-like 3(Ym-1) were detected by RT-qPCR assay. Results : Compared with model group, in low-dose AdipoRon group and high-dose AdipoRon group, serum ALT and AST activities significantly decreased(P<0.05); liver tissues structure were damaged, liver cells degeneration and inflammatory cells infiltration were improved; collagen fiber deposition was also significantly reduced; the relative expression levels of Collagen I, α-SMA and TIMP-1 proteins were significantly down-regulated(P<0.05), while the relative expression levels of MMP-1 protein were significantly up-regulated(P<0.05); the lipid droplets deposition in livers were significantly reduced. The relative Fasn, Scd1 and Cd36 mRNA expression levels in liver tissues were significantly down-regulated(P<0.05), and the relative Pparα and Cpt1α mRNA expression levels were significantly up-regulated(P<0.05); the percentage(%) of CD68+ iNOS+ positive M1-type macrophages significantly decreased(P<0.05); the relative IL-6 and TNF-α mRNA expression levels significantly decreased(P<0.05), the relative Arg1 and Ym-1 mRNA expression levels were significantly up-regulated(P<0.05). In addition, the improvement effects of high-dose AdipoRon group were better than those of low-dose AdipoRon group(P<0.05). Conclusion AdipoRon can improve the disorder of lipid metabolisms, inhibit the M1 type macrophages polarization, and improve the liver fibrosis in CCl4-induced liver fibrosis mice model.

Objective:To detect the levels of sex hormones and insulin in follicular fluid(FF)and the expression level of phosphatase and tensin homolog deleted on chromosome ten(PTEN)in granulosa cells in the infertile patients with polycystic ovary syndrome(PCOS),and to preliminarily explain the correlations between the insulin level and the expression level of PTEN mRNA.Methods:Seventy infertile patients were selected as the subjects and divided into PCOS group and control group(tubal obstruction or infertility due to male factors)according to infertility factors.All patients received in vitro fertilization-embryo transfer(IVF-ET)treatment.FF and ovarian granulosa cells were collected on the day of ovulation.The expression levels of PTEN mRNA in ovarian granulosa cells of the patients in two groups were detected by real-time fluorescence quantitative PCR(RT-qPCR)method.The levels of sex hormone and insulin in FF were measured by electrochemiluminescence.The correlations of the PTEN mRNA expression level in ovarian granulosa cells and testosterone(T)in FF with the level of insulin in FF were analyzed by Spearman correlation analysis method.Results:There were no significant differences in age,infertility years,body mass index(BMI),basic sex hormone,total dose of gonadotropin(Gn)and days of ovulation induction in two groups(P＞0.05).Compared with control group,the anti-Mullerian hormone(AMH)and antral follicle counting(AFC)of the patients in PCOS group were significantly increased(P＜0.05).The RT-qPCR results showed that the PTEN mRNA expression level in ovarian granulosa cells of the patients in the PCOS group was higher than that in control group(P＜0.001).The electrochemiluminescence results showed that the levels of T and insulin in FF of the patients in PCOS group were higher than those in control group(P＜0.05),whereas the estrogen and progesterone levels were lower than those in control group(P＜0.05).The Spearman correlation analysis showed that that T level in FF was positively correlated with the insulin level of the patients in PCOS group(r=0.577,P＜0.001),and the PTEN mRNA expression level in ovarian granulosa cells was positively correlated with the insulin levels in FF(r=0.616,P＜0.001);in control group,there was no correlation between T level and insulin level in FF(r=0.266,P=0.123),and there was no correlation between the expression level of PTEN mRNA in granulosa cells and the insulin level in FF in control group(r=-0.214,P=0.216).Conclusion:The high expression of PTEN in granulosa cells of the infertile patients with PCOS may be related to the local hyperinsulin level in the ovary,and PTEN participates in the occurrence and development of PCOS.

Objective:To investigate the efficacy and treatment adherence of digital cognitive behavioral therapy for insomnia (dCBT-I) in patients with insomnia disorder accompanied by anxiety and depressive symptoms, and to provide empirical evidence for its clinical application.Methods:From December 2023 to December 2024, 102 patients with insomnia disorder accompanied by anxiety and depressive symptoms were recruited from the outpatient department of Inner Mongolia Brain Hospital and randomly assigned to either the dCBT-I group ( n=56) or the digital sleep hygiene education (dSHE) group ( n=46). The dCBT-I group received a 4-week intervention comprising 5 core modules, while the dSHE group received 4 weeks of digital sleep hygiene education. Both groups received weekly guidance from clinical psychologists. Subjective sleep quality (Insomnia Severity Index, ISI), anxiety (Hamilton Anxiety Scale, HAMA), and depressive symptoms (17-item Hamilton Depression Scale, HAMD 17) were assessed at baseline, week 4, week 8, and week 12. Objective sleep parameters (polysomnography, PSG) and cognitive function (Repeatable Battery for the Assessment of Neuropsychological Status, RBANS) were evaluated at baseline and week 4. Linear mixed-effects model was used to analyze the effects of group, timepoint, and their interaction on outcome measures, after controlling medication history, age, sex, education level, ethnicity, and marital status as covariates. Results:A total of 76 patients (dCBT-I: n=42; dSHE: n=34) completed the 4-week intervention, yielding a treatment adherence rate of 74.5%(76/102). At weeks 4, 8, and 12, the dCBT-I group demonstrated significantly lower scores on the ISI, HAMA, and HAMD 17 scales compared to the dSHE group (β=-1.70--0.66, t=-15.38--6.21, all P<0.05), along with higher rates of medication reduction (χ 2=16.40, 9.22, 6.66, all P<0.05). No significant differences were observed in PSG parameters between the two groups. However, the dCBT-I group demonstrated significant improvements in RBANS subdomains, including immediate memory, language function, and delayed memory (β=0.45, 0.86, 1.43, t=3.09, 2.67, 4.36, all P<0.05). Conclusion:dCBT-I is an effective and well-adhered intervention for patients with insomnia disorder accompanied by anxiety and depressive symptoms, warranting broader clinical implementation.
