Acute ischemic stroke (AIS) is a cerebrovascular disease characterized by high morbidity, disability, and mortality, posing a significant threat to human health. Endovascular treatment has now been established as a key method for AIS management, in which stent retrievers that can mechanically remove blood clots play a key role in this technique. In recent years, stent retrievers have evolved in complexity and functionality to improve the ability of clot removing and surgical safety. However, the present instruments still have limitations on treatment efficiency, vascular adaptability, and operational precision, posing an urgent need for innovation in the design of stent retrievers. This paper systematically reviewed the structural features and working principles of AIS stent retrievers from the perspective of efficacy evaluation metrics, historical development, recent advancements in stent retrieval technology, and future prospects.

Objective:To investigate the feasibility and safety of endoscopic surgery in the treatment of fibro-adipose vascular anomaly (FAVA).Methods:Clinical data of FAVA patients who underwent endoscopic treatment admitted to Xi’an International Medical Center Hospital from October 1, 2019 to April 1, 2024 were retrospectively analyzed, including gender, age of onset, age of diagnosis, lesion location, operation time, intraoperative blood loss, hospital stays, incision complications, etc. Before endoscopy, magnetic resonance imaging and ultrasound were routinely used to locate the lesion range, and the surgical position and Trocar location were selected according to different lesion sites.Descriptive statistical analysis was conducted using SPSS version 26.0.Results:40 cases of FAVA patients were admitted during the period, all of whom underwent endoscopic radical resection, including 15 males and 25 females. The age of onset was 8 (6, 12.5) years. The age of diagnosis was 11 (8, 22.5) years. There were 31 patients with stage Ⅰ and 9 patients with stage Ⅱ. 31 cases involved the calf, of which 21 involved the calf triceps (gastrocnemius, soleus) and 9 involved the thigh, of which 1 patient had lesions originating from the fascia around the sciatic neurovascular bundle. 11 cases (27.5%) were converted to open surgery. The operative time was 192.5 (107, 292.5) min. The intraoperative blood loss was 35 (10, 87.5) ml. The length of hospital stay for endoscopic surgery was 9 (7, 11) d. The postoperative follow-up time was 11.5 (3.5, 13.5) months. Of the 40 patients, 39 were cured completely without residual pain or joint movement disorder after operation. Postoperative dorsiflexion function of the ankle joint was mildly limited in one patient classified as stage Ⅱ. There was no incision complication and recurrence.Conclusion:For patients with stage Ⅰ and Ⅱ FAVA, endoscopic surgery has concealed incisions, indistinct scars, definite therapeutic effects and high safety.

Sleep disorders have a high incidence rate in patients with end-stage renal disease(ESRD)and severely affect their quality of life.As the most effective treatment for ESRD,kidney transplantation can significantly improve renal function and prolong survival of patients.However,clinical observations have found that 19.3%to 78.0%of kidney transplant recipients still experience persistent various sleep disorders,such as insomnia,sleep-related breathing disorders and sleep-related movement disorders after surgery.These sleep disorders not only lead to impaired daytime function but are also closely related to adverse outcomes such as cardiovascular complications and increased infection risks.Currently,research on the pathogenesis of sleep disorders in kidney transplant recipients is still insufficient,and clinical diagnosis and treatment face many challenges.This article systematically reviews the epidemiological characteristics,pathophysiological mechanisms,clinical impacts,and new developments in the diagnosis and treatment of sleep disorders in kidney transplant recipients.It aims to provide evidence-based support for clinicians and promote the establishment of more comprehensive early screening and individualized treatment plans to improve the long-term prognosis of recipients.

Background: SM-like (LSM) genes a family of RNA-binding proteins, are involved in mRNA regulation and can function as oncogenes by altering mRNA stability. However, their roles in B-cell progression and tumorigenesis remain poorly understood. Methods: We analyzed gene expression profiles and overall survival data of 123 patients with mantle cell lymphoma (MCL). The LSM index was developed to assess its potential as a prognostic marker of MCL survival. Results: Five of the eight LSM genes were identified as potential prognostic markers for survival in MCL, with particular emphasis on the LSM.index. The expression levels of these LSM genes demonstrated their potential utility as classifiers of MCL. The LSM.index-high group exhibited both poorer survival rates and lower RNA levels than did the overall transcript profile. Notably, LSM1 and LSM8 were overexpressed in the LSM.index-high group, with LSM1 showing 2.5-fold increase (p < 0.001) and LSM8 depicting 1.8-fold increase (p < 0.01) than those in the LSM.index-low group.Furthermore, elevated LSM gene expression was associated with increased cell division and RNA splicing pathway activity. Conclusions The LSM.index demonstrates potential as a prognostic marker for survival in patients with MCL. Elevated expression of LSM genes, particularly LSM1 and LSM8, may be linked to poor survival outcomes through their involvement in cell division and RNA splicing pathways. These findings suggest that LSM genes may contribute to the aggressive behavior of MCL and represent potential targets for therapeutic interventions.

Purpose Hydrogen proton magnetic resonance imaging was used to study the brain metabolism of menstrual-related migraine(MRM)in different states,and to investigate its correlation with clinical features and estrogen and progesterone.Materials and Methods We recruited 36 patients with MRM diagnosed by neurology outpatient experts of the First Affiliated Hospital of Henan University of Science and Technology from April 2019 to August 2022,and also recruited 29 normal women with age-and education-matched.Proton magnetic resonance spectroscopy was used to assess neurochemical brain changes during interictal period(late follicular phase)and ictal period(perimenstrual phase)in them.The point resolved spectroscopic sequence was used to focus on the bilateral medial prefrontal cortex(mPFC)and bilateral thalamus.Sex hormone levels were collected on the same day of MRI acquisition.The ratios of NAA/Cr,GABA/Cr,Glx/Cr and Cho/Cr were observed.Metabolite changes and hormone levels were investigated among two groups.Furthermore,metabolite changes were investigated in a longitudinal design during the interictal period and ictal period.Results There were no significant differences in the levels of estrogen and progesterone both in the late follicular and perimenstrual periods.There were no significant differences in decline rate of them in perimenstrual periods between patients and normal people(P>0.05).During interictal period,the ratio of Cho/Cr in the region of left mPFC was lower significantly in the MRM group than that of control group(U=-2.957,P=0.003)and showed a significant negative correlation with attack frequency(r=-0.398,P=0.018).During ictal period,the women with MRM had significantly lower the ratio of GABA/Cr in the left mPFC and higher the ratio of Glx/Cr in the left thalamus compared to those of controls(U=-2.015,P=0.044;t=2.213,P=0.033).We found no significant correlations between these results and magraine characteristics(P>0.05).In addition,we found the ratio of GABA/Cr did not change(P>0.05),the ratio of Glx/Cr and Cho/Cr in right thalamus increased from interictal towards the ictal state for MRM patients(t=-2.181,P=0.038;Z=-2.414,P=0.016).Conclusion The present study suggests the existence of distinct cerebral metabolism states between MRM and control,and there are dynamic changes in cerebral metabolism with headache attacks.However,there is no significant difference in estrogen and progesterone from normal women,and its neural mechanism still needs to be further studied.

The gut microbiome shows changes under a plateau environment, while the disbalance of intestinal microbiota plays an important role in the pathogenesis of irritable bowel syndrome (IBS); however, the relationship between the two remains unexplored. In this work, we followed up a healthy cohort for up to a year before and after living in a plateau environment and performed 16S ribosomal RNA (rRNA) sequencing analysis of their fecal samples. Through evaluating the participants' clinical symptoms, combined with an IBS questionnaire, we screened the IBS sub-population in our cohort. The sequencing results showed that a high-altitude environment could lead to changes in the diversity and composition of gut flora. In addition, we found that the longer the time volunteers spent in the plateau environment, the more similar their gut microbiota composition and abundance became compared to those before entering the plateau, and IBS symptoms were significantly alleviated. Therefore, we speculated that the plateau may be a special environment that induces IBS. The taxonomic units g_Alistipes, g_Oscillospira, and s_Ruminococcus_torques, which had been proved to play important roles in IBS pathogenesis, were also abundant in the IBS cohort at high altitudes. Overall, the disbalance of gut microbiota induced by the plateau environment contributed to the high frequency of IBS and the psychosocial abnormalities associated with IBS. Our results prompt further research to elucidate the relevant mechanism.
