The development of biosimilar products or follow-on biologics has been flourishing in recent years because of their lower price than the originators. In this study, a multivariate data analysis method based on JMP software was proposed to assess the glycosylation pattern similarity of antibody candidates from different conditions in optimization experiments with a reference. A specific distance was generated by this method and indicated the glycoform similarity between the biosimilar and the reference. This method can be applied to analyze the similarity of other physicochemical and functional characteristics between follow-on biologics and originators. Then, the design of experimental methods can be realized to optimize the conditions of cell culture to attain similar antibody candidates. A higher concentration of GlcNAc added to the basal media made the glycan of the antibody more similar to the glycan of the reference in this study.

Department of Nasopharyngeal Carcinoma, Sun Yat-sen University Cancer Center, Guangzhou, P.R. China.
Background: Central venous access devices (CVAD) are widely used in patient care, providing an essential, reliable pathway for patients to receive chemotherapy, long-term infusions, and nutritional support. However, a system of exercise management has not been developed in patients with CVAD.
Purpose: To evaluate and summarize the evidence for management exercise in patients with CVAD and provide guidance for clinical practice.
Success Rate of Endoscopic Third Ventriculostomy in Children Younger Than 1 Year With Idiopathic Congenital Aqueductal Stenosis and Long-term Follow-up.

Department of Neurosurgery, University Hospital Ostrava, Ostrava, Czech Republic.
Introduction: The indication for endoscopic third ventriculostomy is often contested in children younger than 1 year. This study aims to establish the benefits of this modality in children with idiopathic congenital aqueductal stenosis.
Methods: Retrospective analysis was performed on patients <1 year old with idiopathic congenital aqueductal stenosis undergoing endoscopic third ventriculostomy between 2004 and 2020.

Background: Neuromuscular disorders (NMDs) constitute a heterogeneous group of disorders that affect motor neurons, neuromuscular junctions, and muscle fibers, resulting in symptoms such as muscle weakness, fatigue, and reduced mobility. These conditions significantly affect patients' quality of life and impose a substantial burden on caregivers. Spinal muscular atrophy (SMA) is a relatively common NMD in children that presents in various types with varying degrees of severity.

Department of Radiology, Zhongshan Hospital, Fudan University, Shanghai, China.
Background: Adopting appropriate noninvasive radiological method is crucial for periodic surveillance of liver metastases in colorectal cancer (CRC) patients after surgery, which is closely related to clinical management and prognosis. This study aimed to prospectively enroll stage II-III CRC patients for the surveillance of liver metastases, and compare the diagnostic performance of contrast-enhanced CT (CE-CT) and non-enhanced abbreviated MRI (NE-AMRI) during this process.
Methods: 587 CRC patients undergoing radical resection of the primary tumor were evaluated by 1 to 3 rounds of surveillance tests, consisting of abdominal CE-CT and contrast-enhanced MRI (CE-MRI) within 7 days at 6-month intervals.
