Heart and spleen deficiency syndrome is the most common syndrome type in patients with insomnia. Based on the theory of disease syndrome-combined animal model, this paper used multiple databases to search for the keywords "heart and spleen deficiency", "insomnia", "sleepless", "disease syndrome-combined animal model", "model evaluation", etc. It selected the literature related to the animal model of insomnia with heart and spleen deficiency in the past 20 years to evaluate from the aspects of model establishment, modeling factors, syndrome model, disease model, macro characterization & macro characterization evaluation scale, micro indicators, etc. It is found that the existing animal model of insomnia with heart and spleen deficiency is not completely constructed by the method of disease syndrome combination of disease modeling factors and syndrome modeling factors. In the model using this method, the single establishment factor of heart and spleen deficiency does not conform to the clinical reality of disease, and the selection of the factors for the insomnia model is not closely related to or even separated from the syndrome performance. There is a problem of insufficient quantification of macro representation when the macro representation of the model replaces the symptoms related to heart and spleen deficiency syndrome and insomnia in an equivalent manner for macro representation evaluation, which can be improved according to the quantitative ideas and examples of the existing macro representation and macro representation evaluation scale. There are few specific indicators of heart and spleen deficiency syndrome in micro indicators. The micro research of heart and spleen deficiency syndrome and the essence of other traditional Chinese medicine (TCM) syndromes can be carried out by metabonomics and other technologies combined with the theory of corresponding prescription and syndrome, along the specific related ideas of "prescription and syndrome, treatment principle and selection of prescription, treatment principle and selection of acupoints, as well as therapeutic mechanism and syndrome essence". The future users and researchers of animal models of insomnia with heart and spleen deficiency can get improved methods and ideas through the shortcomings of animal models of heart and spleen deficiency listed in this paper and construct animal models of insomnia with heart and spleen deficiency that are more suitable for clinical practice, so as to establish a more perfect modeling method and evaluation system of disease syndrome-combined animal model.

Objective:To explore the safety and efficacy of intrasaccular flow disruptor in intracranial aneurysms, including wide-necked aneurysms.Methods:A retrospective analysis was performed; 102 patients with intracranial aneurysms treated with intrasaccular flow disruptor at Department of Neurointervention, First Affiliated Hospital of Zhengzhou University from August 2022 to November 2024 were enrolled; their clinical and imaging data were collected. The aneurysm characteristics and perioperative complications were summarized; aneurysm occlusion was evaluated by Woven EndoBridge occlusion scale (WOS) immediately after surgery and during the follow-up period.Results:Among the 102 aneurysms, 33 were anterior cerebral artery aneurysms, 40 were middle cerebral artery aneurysms, 17 were internal carotid artery aneurysms and 12 were basilar artery aneurysms; 73 aneurysms were regular intracranial saccular aneurysms and 29 were irregular saccular ones (17 of them with daughter sacs); 12 aneurysms were ruptured at acute phase. The surgical success rate was 100%: single intrasaccular flow disruptor was implanted into 95 patients, and stent-assisted or salvage treatments were given to 7 patients). Immediately after surgery, WOS grading A was noted in 5 patients, grading B in 7, grading C in 31, and grading D in 59. Two patients suffered severe perioperative complications and passed away: one patient died for ischemic complications that ensued after stent salvage treatment (parent artery being compressed by intrasaccular flow disruptor); the other patient died for hemorrhagic complications triggered by rupture of an initially unruptured aneurysm following intrasaccular flow disruptor implantation. Among them, 52 patients completed postoperative DSA follow-up, with a median follow-up of 205 (168, 292) days; WOS grading A was noted in 31 patients, grading B in 9, grading C in 8, and grading D in 4 at the last follow-up; the full occlusion rate was 92.3%, and no ischemic or hemorrhagic adverse events occurred.Conclusion:Intrasaccular flow disruptor shows high short-term safety and good efficacy in the treatment of intracranial aneurysms.

OBJECTIVES:
To analyze the potential causal relationship between gut microbiota and food allergy (FA) using two-sample Mendelian randomization (MR) methods.
METHODS:
Data from genome-wide association studies on gut microbiota and FA were utilized. MR analysis was conducted employing inverse variance weighting, MR-Egger regression, and weighted median methods to assess the causal relationship between gut microbiota and FA. Cochrane's Q test was used to evaluate heterogeneity of instrumental variables, MR-PRESSO analysis was conducted to test for outliers and pleiotropy, and MR-Egger regression was employed to assess horizontal pleiotropy. The "leave-one-out" method was used to evaluate the impact of removing individual single nucleotide polymorphisms on the causal relationship.
RESULTS:
Inverse variance weighting analysis revealed that the phylum Verrucomicrobia, family Verrucomicrobiaceae, order Verrucomicrobiales, genus Ruminococcaceae UCG013, and genus Akkermansia were negatively associated with FA (P<0.05). Sensitivity analyses confirmed the reliability of the findings, indicating no heterogeneity or pleiotropy present.
CONCLUSIONS
There is a causal relationship between gut microbiota and FA, with Verrucomicrobia, Verrucomicrobiaceae, Verrucomicrobiales, Ruminococcaceae UCG013, and Akkermansia potentially reducing the risk of developing FA. These findings provide potential targets for the treatment and prevention of FA; however, further research is needed to explore the specific mechanisms by which the microbiota influence FA.

Objective To compare the clinical outcomes of the clomiphene citrate(CC)dual stimulation protocol and the luteal phase ovarian stimulation protocol after natural cycle oocytes retrieved in POSEIDON patients with low expected prognosis.Methods The clinical data from patients who underwent in vitro fertilization(IVF)or intracytoplasmic sperm injection(ICSI)at the Reproductive Center of the Third Affiliated Hospital of Zhengzhou University from May 2016 to December 2023 were analyzed retrospectively.According to the POSEI-DON criteria,including POSEIDON group 3 and group 4,which were treated with the CC dual stimulation protocol(the CC group)and the luteal-phase ovarian stimulation protocol after the natural cycle oocytes retrieval(the natural cycle group).The basic data and clinical outcomes of the two ovulation protocols were analyzed,and the main observations included the number of oocytes retrieved,the cumulative clinical pregnancy rate and the cumulative live birth rate,and explored the impact of ovulation promotion regimens on clinical outcomes through binary logis-tic regression.Results On the whole,there was no significant difference in the total number of oocytes retrieved,cumulative clinical pregnancy rate and live birth rate between the CC group and the natural cycle group(all P>0.05),And in POSEIDON group 4,the numbers of oocytes retrieved in the follicular phase of the CC group were higher than those in the natural cycle group,whereas the number of oocytes retrieved in the luteal phase of natural cycle group were higher,and the difference was statistically significant(P<0.05).After logistic regression analysis,the ovulation stimulation protocols did not affect the cumulative clinical pregnancy rate and live birth rate of POSEI-DON 3 and 4 group(P>0.05).Conclusions For the POSEIDON patients with a low expected prognosis,the clinical effectiveness of the luteal phase ovarian stimulation protocol after natural cycle oocytes retrieved is not inferior to that of the CC dual stimulation protocol.In POSEIDON group 4,on the premise that the AMH levels of patients in the natural cycle group were lower than those in the CC group,who underwent natural cycle ovulation followed by luteal phase induction achieved similar clinical outcomes to those of the CC dual stimulation protocol group.Therefore,the luteal phase ovarian stimulation protocol after natural cycle oocytes retrieved should be more clinically recommended for POSEIDON group 4 patients.

Objective:To investigate the influencing factors and perinatal outcomes associated with monozygotic twins (MZT) following elective single embryo transfer (eSET) via in vitro fertilization or intracytoplasmic sperm injection and embryo transfer (IVF/ICSI-ET). Methods:A retrospective cohort study was conducted on 12 079 patients who achieved pregnancy after undergoing IVF/ICSI-eSET at Reproductive Health Hospital of the Third Affiliated Hospital of Zhengzhou University between January 2015 and September 2023. Patients were stratified into two groups based on ultrasound findings 30 d post-transfer: singleton pregnancy group and MZT pregnancy group. Finally, 300 MZT and 1 500 single pregnancies, which were randomly matched according to 1∶5 were included by study period. General patients' characteristics, embryo-related factors, and perinatal outcomes were compared between the two groups. A multivariate logistic regression model was employed to identify risk factors for MZT after single embryo transfer, adjusting for potential confounding variables.Results:The incidence of twin pregnancy following single embryo transfer was 2.48% (300/12 079), which was higher than that of naturally conceived monozygotic twin pregnancy. No significant difference was found in baseline characteristics between the two groups (all P>0.05). The blastocyst transfer rate was higher in the MZT pregnancy group [93.3% (280/300)] than in the singleton pregnancy group [88.8% (1 332/1 500), P=0.022]. Multivariate logistic regression analysis also showed that blastocyst transfer was associated with an increased risk of MZT ( OR=0.552, P=0.016, 95% CI: 0.341-0.894). Analysis of blastocyst cycles showed that the risk of MZT was higher when transferring high-quality blastocysts [79.6% (223/280) vs. 67.8% (903/1 332), P<0.001], where as a trophectoderm (TE) grading of C [20.4% (57/280) vs. 32.2% (429/1 332), P<0.001] had a lower risk of MZT. After adjusting for confounding factors, the risk of MZT was found to increase with the transfer of blastocysts with a B-grade inner cell mass (ICM) ( OR=0.601, P=0.001, 95% CI: 0.442-0.819) and A/B grade TE (grade A: OR=2.951, P<0.001, 95% CI: 1.980-4.399; grade B: OR=1.840, P<0.001, 95% CI: 1.315-2.576). The risk of complications during pregnancy [47.7% (143/300) vs. 19.3% (289/1 500), P<0.001], preterm labor [55.1% (140/254) vs. 7.4% (101/1 368), P<0.001], and the risk of stillbirth [3.7% (11/300) vs. 1.5% (22/1 500), P=0.016] were significantly higher in the MZT pregnancy group than in the singleton pregnancy group. Conclusion:Assisted reproductive technology may contribute to the risk of MZT. Transfer of blastocysts, particularly those with loose ICM arrangement and dense TE arrangement, appears to increase the risk of MZT in patients undergoing eSET.
