Objective:To evaluate the efficacy and safety of intrasaccular flow disruptor in wide-necked intracranial aneurysms.Methods:One hundred and seventeen patients with wide-necked intracranial aneurysms treated with intrasaccular flow disruptor were collected from Department of Neurointervention (First Affiliated Hospital of Zhengzhou University), Department of Neurosurgery (Beijing Tiantan Hospital, Capital Medical University), Department of Cerebrovascular Surgery, Neurosurgery Center (Zhujiang Hospital, Southern Medical University), and Department of Neurosurgery (First Affiliated Hospital of Harbin Medical University) from August 2022 to March 2024. Raymond-Roy Occlusion Classification (RROC) was employed to evaluate aneurysm embolization immediately after procedure; cranial CT or MRI within 48 hours of embolization were performed to identify any new intracranial hemorrhage, subarachnoid hemorrhage, or new symptomatic cerebral infarction related to the intracranial aneurysms. Modified Rankin Scale (mRS) was used to assess the neurological function at discharge. Imaging follow-up and outpatient follow-up were performed at 6 months after embolization to evaluate the aneurysm occlusion degree and complications.Results:A total of 117 intrasaccular flow disruptors were implanted in 117 patients, with a technical success rate of 100%; 115 patients (98.3%) enjoyed successful one-time release of their disruptors, and 2 patients (1.7%) required retrieval and redirection of the disruptors before second successful attempt. Flow disruptor plus stent was performed in 13 patients (11.1%). Immediately after procedure, RROC grading I was noted in 3 patients, grading II in 51 patients and grading III in 63 patients. Cranial CT or MRI within 48 hours of embolization indicated no new intracranial hemorrhage, subarachnoid hemorrhage, or symptomatic cerebral infarction related to the intracranial aneurysms. All patients had mRS score of 0 at discharge. Eighty-three patients completed a 6-month follow-up (RROC grading I in 41 patients, grading II in 33 patients and grading III in 9 patients), without ischemic or hemorrhagic adverse events.Conclusion:The results of this study preliminarily suggest that intrasaccular flow disruptor is effective and safe in wide-necked intracranial aneurysms.

Objective:To evaluate the efficacy and safety of Neuroform Atlas stent-assisted coil embolization in patients with middle cerebral artery bifurcation aneurysms.Methods:A retrospective analysis was performed; the clinical data of 46 patients with middle cerebral artery bifurcation aneurysms accepted Neuroform Atlas stent-assisted coil embolization in First Affiliated Hospital of Zhengzhou University, Beijing Tiantan Hospital Affiliated to Capital Medical University, First Affiliated Hospital of Harbin Medical University, Zhujiang Hospital of Southern Medical University and First Affiliated Hospital of Chongqing Medical University from January 2022 to March 2024 were collected. There were 28 ruptured aneurysms (60.87%) and 18 unruptured aneurysms (39.13%). Follow-up was performed for more than 3 months; Raymond-Roy grading was used to evaluate the aneurysm embolization immediately after embolization and during follow-up; perioperative hemorrhagic or ischemic complications were recorded; modified Rankin Scale (mRS) was used to evaluate the prognosis of the patients at discharge and during follow-up (mRS score≤2: good prognosis, and mRS score>2: poor prognosis).Results:Coil embolization was successful in all 46 patients. DSA immediately after embolization showed that 41 patients (89.13%) had completely occluded aneurysms (Raymond-Roy grading I), 2 patients (4.35%) had residual aneurysm neck (Raymond-Roy grading Ⅱ) and 3 patients (6.52%) had partially occluded aneurysms (Raymond-Roy grading Ⅲ). Perioperative complications occurred in 5 patients, including 2 with postoperative cerebral infarction, 1 with hydrocephalus, 1 with postoperative pneumonia leading to respiratory failure, and 1 with stent thrombosis during embolization. Both at discharge and 3 months after embolization, 43 patients (93.48%) had good prognosis and 3 patients (6.52%) had poor prognosis. No obvious ischemic complications (such as stent restenosis) or hemorrhagic complications (such as re-rupture of the aneurysms) were found in all patients. Thirty patients (65.22%) had imaging follow-up for 6-12 months: 26 (86.67%) had Raymond-Roy grading I, 3 (10.00%) had Raymond-Roy grading II, and 1 (3.33%) had Raymond-Roy grading III.Conclusion:Neuroform Atlas stent-assisted coil embolization has good short-term efficacy and high safety in middle cerebral artery bifurcation aneurysms, but long-term follow-up observation is still needed to verify its efficacy.

ObjectiveTo observe the effects of Tongmai Kaiqiao pills on the hypoxia-inducible factor-1α （HIF-1α）/adenovirus E1B 19 kD-interacting protein 3 （BNIP3） signaling pathway and mitochondrial autophagy in the hippocampus of the rat model of vascular dementia （VD）. MethodNinety male SD rats underwent adaptive feeding for one week before the study. Ten rats were randomly assigned to the sham group， where the common carotid artery was isolated without ligation. The remaining rats were subjected to sequential ligation of the common carotid artery for the modeling of VD. The successfully modeled rats were randomly assigned into the following groups： model， high-， medium-， and low-dose （27.6， 13.8， 6.9 g·kg^-1， respectively） Tongmai Kaiqiao pills， donepezil hydrochloride （0.45 mg·kg^-1）， and combination （27.6 g·kg^-1 Tongmai Kaiqiao pills + 2.5 mg·kg^-1 HIF-1α inhibitor YC-1） groups. After 4 weeks of treatment， samples were collected. Nissl staining and hematoxylin-eosin staining were performed to observe the loss of neurons and pathological changes， respectively， in the hippocampal region. Western blot was employed to determine the protein levels of HIF-1α， BNIP3， Beclin-1， and microtubule-associated protein 1 light chain 3B （LC3B） in the hippocampal tissue. Transmission electron microscopy was used to observe the mitochondrial ultrastructure and the number of autophagosomes in the hippocampal tissue. Immunofluorescence was employed to observe the fluorescence intensity of HIF-1α， BNIP3， and LC3B in the hippocampal tissue. ResultCompared with the sham group， the model group showed prolonged escape latency （P<0.01）， decreased number of platform crossings （P<0.01）， reduced and disarranged neuronal layers in the hippocampal region， decreased number of Nissl bodies， disrupted mitochondrial cristae， damaged mitochondrial double-membrane structures， increased number of autophagosomes， upregulated expression of HIF-1α， BNIP3， beclin1， and LC3B （P<0.05， P<0.01）， and enhanced fluorescence intensity of HIF-1α， BNIP3， and LC3B （P<0.05， P<0.01）. Compared with the model group， Tongmai Kaiqiao pills and donepezil hydrochloride shortened the searching time for the platform （P<0.01） and increased the number of platform crossings （P<0.01）. Moreover， the drugs increased the number of neurons with normal morphology and orderly arrangement and the number of Nissl bodies， alleviated the damage， increased the number of autophagosomes， upregulated the expression of HIF-1α， BNIP3， Beclin1， and LC3B （P<0.05， P<0.01）， and enhanced the fluorescence intensity of HIF-1α， BNIP3， and LC3B （P<0.05， P<0.01）. Compared with high-dose Tongmai Kaiqiao pills， the combination group prolonged the escape latency （P<0.01）， reduced the number of crossing platforms （P<0.01）， decreased the number of hippocampal neurons， aggravated the damage， decreased the number of Nissl bodies and autophagosomes， downregulated the expression of HIF-1α， BNIP3， beclin1， and LC3B （P<0.01）， and decreased the fluorescence intensity of HIF-1α， BNIP3， and LC3B （P<0.01）. ConclusionTongmai Kaiqiao pills may activate the HIF-1α/BNIP3 signaling pathway to promote the occurrence of mitochondrial autophagy， clear damaged mitochondria， provide energy for healthy cells， reduce neuronal cell death， and restore the brain function， thereby reducing ischemic damage to the hippocampal tissue， improving learning and memory abilities， and exerting therapeutic effects on VD in rats.

Objective: To investigate the current status and influencing factors of sleep disorders among pregnant women, so as to provide insights into health management during pregnancy. Methods: Pregnant women who underwent prenatal checkups at Hangzhou Obstetrics and Gynecology Hospital from January to October 2023 were selected as subjects, and general data including age, pregnancy period and exercise were collected through questionnaire surveys. Sleep quality, pregnancy stress, anxiety and depression were evaluated using Pittsburgh Sleep Quality Index, Pregnancy Stress Rating Scale, Pregnancy-related Anxiety Scale and Edinburgh Postnatal Depression Scale, respectively. Factors affecting sleep disorders among pregnant women were analyzed using a multivariable logistic regression model. Results: A total of 386 pregnant women was surveyed, with a mean age of (30.28±4.65) years, including 20.47% in the first trimester, 47.93% in the second trimester and 31.61% in the third trimester. Women with anxiety and depression accounted for 14.51% and 21.76%, respectively. Pregnancy stress was mainly moderate, accounting for 51.04%. There were 106 pregnant women with sleep disorders, accounting for 27.46%. Mutivariable logistic regression analysis showed that age (≥35 years, OR=1.656, 95%CI: 1.094-2.503), pregnancy period (third pregnancy, OR=2.097, 95%CI: 1.213-3.621), regular exercise in the past 6 months (OR=0.376, 95%CI: 0.210-0.670), anxiety (OR=2.794, 95%CI: 1.545-5.048), depression (OR=3.501, 95%CI: 1.877-6.529) and pregnancy stress (moderate, OR=1.355, 95%CI: 1.018-1.801; severe, OR=2.538, 95%CI: 1.417-4.540) were the factors affecting sleep disorders among pregnant women. Conclusions Sleep disorders of pregnant women is influenced by age, pregnancy period, pregnancy stress, anxiety, depression and exercise. It is necessary to identify high-risk individuals with sleep disorders early, and to provide psychological intervention and prenatal health guidance.

Objective:To investigate the efficacy and safety of high semi-decubitus position in the second stage of labor in epidural analgesic delivery of primipara.Methods:A total of 120 women who gave birth in Hang-zhou women's Hospital from May 1,2021 to July 30,2021 were randomly divided into experimental group(n=60)and control group(n=60)by random number table method.The control group adopted supine position in the sec-ond stage of labor,and the experimental group transferred to high semi-supine position after the supine position was used applied for 30 minutes when the fetal head was not exposed.To compare the effects of different postur-al positions on the duration of the second stage of labor,mode of delivery,postpartum injury,perineal tearing,la-bor force experience and labor control,and neonatal asphyxia.Results:The duration of uterine opening to fetal head exposure,the duration of uterine opening to fetal head crown and the duration of second stage of labor in experimental group were shorter than those in control group.The rate of natural delivery of experimental group was higher than that of control group.The episiotomy rate and the second degree perineal laceration rate were lower than that of control group.The amount of blood loss during delivery and 2h postpartum of experimental group was less than that of control group.The scores of birth experience and birth control of experimental group were higher than those of control group,and the differences were statistically significant(P＜0.05).There was no significant difference in 1-minute Agpar score and 5-minute Agpar score between the two groups(P＞0.05).Conclusions:The application of high semi-decubitus position under epidural labor analgesia promoted vaginal natural labor,shortened the time of second stage of labor,reduced episiotomy rate and perineal laceration de-gree,reduced postpartum hemorrhage,had positive labor force experience,and increased the sense of labor con-trol.

Objective:The present study used single-cell RNA sequencing(scRNA-seq)to characterize the cellular composition of ovarian carcinosarcoma(OCS)and identify its molecular characteristics.Methods:scRNA-seq was performed in resected primary OCS for an in-depth analysis of tumor cells and the tumor microenvironment.Immunohistochemistry staining was used for validation.The scRNA-seq data of OCS were compared with those of high-grade serous ovarian carcinoma(HGSOC)tumors and other OCS tumors.Results:Both malignant epithelial and malignant mesenchymal cells were observed in the OCS patient of this study.We identified four epithelial cell subclusters with different biological roles.Among them,epithelial subcluster 4 presented high levels of breast cancer type 1 susceptibility protein homolog(BRCA1)and DNA topoisomerase 2-α(TOP2A)expression and was related to drug resistance and cell cycle.We analyzed the interaction between epithelial and mesenchymal cells and found that fibroblast growth factor(FGF)and pleiotrophin(PTN)signalings were the main pathways contributing to communication between these cells.Moreover,we compared the malignant epithelial and mesenchymal cells of this OCS tumor with our previous published HGSOC scRNA-seq data and OCS data.All the epithelial subclusters in the OCS tumor could be found in the HGSOC samples.Notably,the mesenchymal subcluster C14 exhibited specific expression patterns in the OCS tumor,characterized by elevated expression of cytochrome P450 family 24 subfamily A member 1(CYP24A1),collagen type XXIII α1 chain(COL23A1),cholecystokinin(CCK),bone morphogenetic protein 7(BMP7),PTN,Wnt inhibitory factor 1(WIF1),and insulin-like growth factor 2(IGF2).Moreover,this subcluster showed distinct characteristics when compared with both another previously published OCS tumor and normal ovarian tissue.Conclusions:This study provides the single-cell transcriptomics signature of human OCS,which constitutes a new resource for elucidating OCS diversity.
