Abstract Migraine is a widespread neurovascular disorder, the pathogenesis of which is closely linked to the release of calcitonin gene-related peptide(CGRP), leading to a significant impairment in patients′ quality of life. CGRP receptor antagonists exert their therapeutic effect by inhibiting the interaction between CGRP and its receptors, thereby preventing migraine attacks. Currently, several agents, including Rimegepant and Ubrogepant, have either received approval from the U. S. Food and Drug Administration or are in advanced stages of clinical trials.These drugs offer multiple advantages, such as the absence of vasoconstrictive effects, a rapid onset of action, and minimal interference with the immune system. Nevertheless, further investigation is necessary to assess their longterm safety, the potential emergence of drug resistance, and the development of individualized treatment protocols.Moreover, the integration of these novel therapies with existing treatment strategies remains a critical area for future research. This review aims to summarize recent national and international scientific advancements to establish a theoretical basis for the application of precision medicine in migraine management.

Objective:To investigate the potential risk factors for cryptogenic stroke (CS) in patients with patent foramen ovale (PFO).Methods:Patients underwent PFO closure in the Department of Cardiovascular Surgery, the Second Hospital of Hebei Medical University from June 2018 to December 2021 were enrolled retrospectively. Transesophageal echocardiography was used to evaluate the morphological characteristics of foramen ovale and right-to-left shunt (RLS). Multivariate logistic regression analysis was used to determine the independent risk factors for CS in patients with PFO. Results:A total of 203 patients with PFO were enrolled. Their age was 41.9±14.3, and 116 patients (57.1%) were male. There were 102 patients in CS group and 101 patients in non-stroke group. The age, body mass index, systolic blood pressure and diastolic blood pressure, and the constituent ratios of male, hypertension, diabetes, hyperlipidemia and smoking of the CS group were significant higher than those of the non-stroke group (all P<0.05). The PFO channel of the CS group was longer, wider and more combined with resting RLS (all P<0.05). Multivariate logistic regression analysis showed that systolic blood pressure (odds ratio [ OR] 1.065, 95% confidence interval [ CI] 1.022-1.111; P=0.003), PFO length ( OR 1.124, 95% CI 1.004-1.258; P=0.043) and resting RLS ( OR 5.449, 95% CI 2.283-13.004; P<0.001) were the independent risk factors for CS in patients with PFO. Conclusion:Systolic blood pressure, PFO length and the presence of resting RLS are the independent risk factors for CS in patients with PFO.

Cryptogenic stroke (CS) is a type of stroke that can not find the exact cause after using the standard clinical examination procedure of stroke. In recent years, many studies have shown that patent foramen ovale (PFO) is closely associated with CS, and its main pathogenesis is paradoxical embolism. In clinical practice, ultrasound is often used for PFO screening. In the context of PFO, the secondary prevention of CS includes drug therapy and PFO closure, but the choice of treatment is still controversial. Screening and evaluation of possible PFO will help to develop secondary prevention strategies for patients with CS, especially those who can benefit from PFO closure.

Obesity and its associated complications are highly related to a current public health crisis around the world. A growing body of evidence has indicated that G-protein coupled bile acid (BA) receptor TGR5 (also known as Gpbar-1) is a potential drug target to treat obesity and associated metabolic disorders. We have identified notoginsenoside Ft1 (Ft1) from

Objective: To summarize the isolation characteristics and drug resistance of HACEK bacteria in lower respiratory tract infection of coal worker's pneumoconiosis. Methods: From 2016 to 2018, K-B method and MIC method were used to test the susceptibility of 10 commonly used antimicrobial agents to isolated 46 strains of HACEK bacteria, and the drug resistance of lactamase and non-enzyme producing haemophilus was compared. Results: Haemophilus influenza (Hi) accounted for 71.74% (33/46) of the HACEK bacteria in the lower respiratory tract infection patients of coal workers' pneumoconiosis in our hospital, Haemophilus parainfluenzae (HPi) accounted for 23.91% (11/46) , which corroded one strain of Eikenella and one strain of actinomycetes. HACEK bacteria were isolated most in winter and spring, and less in summer and autumn. Cefuroxime, ceftriaxone, amoxicillin/clavulanic acid and levofloxacin have good antimicrobial activity against HACEK bacteria. The sensitivity of non-enzyme-producing strains Tetracycline (TE) , Compound trimethoprim (SXT) , Azithromycin (AZI) and Ampicillin (AMP) was stronger than that of enzyme-producing strains (P<0.05) . Conclusion Hi is the main HACEK bacteria isolated from patients with lower respiratory tract infection of coal worker's pneumoconiosis, followed by Hpi. The enzyme-producing strains of these bacteria are resistant to AMP, SXT and AZI to some extent. These drugs should not be the first choice for treatment.

Objective To analyze the surgical technique and success rate of endoscopic third ventriculostomy (ETV) in pediatric obstructive hydrocephalus.Methods A retrospective analysis of clinical data and treatment efficacy of 13 patients with pediatric obstructive hydrocephalus,admitted to and undergone ETV in our hospital fiom July 2008 to July 2014,was performed.All patients were confirmed by CT and MR imaging.Results Follow-up information for all patients was obtained every 6 months by telephone after operation.Re-check was performed in all patients by CT or MR imaging.Ten had signs of hydrocephalus greatly relieved or disappeared;3 were invalid,and ventriculoperitoneal shunt was then performed 3-12 months after ETV.Postoperative fever occurred in 2 children and epilepsy in one.No complications,such as cerebrospinal fluid leakage,bleeding,infection or nerve injury,were noted.Conclusion ETV in treatment of children with obstructive hydrocephalus is safe and effective,enjoying few complications.
