Evaluation of Factors Influencing Postoperative Cognitive Dysfunction in Patients After Cranial Tumor Surgery.

Background: The authors retrospectively analyzed the perioperative data of 81 patients who underwent cranial tumor surgery to explore the factors influencing POCD in patients after the surgery.

Methods: The authors evaluated preoperative cognitive dysfunction using the Mini-Mental State Examination (MMSE) score measured. For patients whose cognitive function was normal, the authors retrieved the MMSE score on the seventh day after surgery and compared it to determine whether the patients had POCD.

Evaluation indices of the temperature difference of subgrade and the optimization of mitigation measures in cold regions.

With the construction and operation of railways in cold regions, the asymmetric deformation of subgrades due to the difference in the transverse ground temperature has become a prominent issue. A comprehensive evaluation of the transverse ground temperature difference and investigation of the corresponding mitigation measures should be conducted to avoid or minimize the damage resulting from this difference, thereby improving subgrade stability and reducing deformation. In this study, the time history variations in the homogeneity and symmetry indices of the ground temperature at typical instances that reflect the spatial and temporal changes in the temperature difference of the subgrade were proposed as evaluation indices.

Elucidating the interaction of rhizosphere bacteria and environmental factors in influencing active ingredient content of Lycium barbarum fruit in China.

Aims: This study aimed to compare the differences in the bacterial community structure of Lycium barbarum rhizosphere and elucidate the contribution of rhizosphere bacteria to the active ingredients of L. barbarum fruit.

Methods And Results: This study investigated the soil and meteorological characteristics of L.

An Immune-Related Prognostic Classifier Is Associated with Diffuse Large B Cell Lymphoma Microenvironment.

Background: Diffuse large B cell lymphoma (DLBCL) is a life-threatening malignant tumor characterized by heterogeneous clinical, phenotypic, and molecular manifestations. Given the association between immunity and tumors, identifying a suitable immune biomarker could improve DLBCL diagnosis.

Methods: We systematically searched for DLBCL gene expression microarray datasets from the GEO database.

Inner ear structure of miniature pigs measured by multi-planar reconstruction techniques.

To study the structures of the scala vestibuli and tympani of miniature pigs in order to evaluate the feasibility of using miniature pigs as the animal model for cochlear implant. The temporal bones of three miniature pigs with normal hearing were scanned by micro-CT. With the aid of the Mimics software, we reconstructed the 3D structure of inner ear basing on the serial images of the miniature pig, and obtained dimensions of the scala vestibuli and tympani with multi-planar reconstruction (MPR) technique.

[Clinical analysis of extracranial and intracranial complications of cholesteatoma otitis media].

Objective: To study the clinical feature of extracranial and intracranial complications caused by cholesteatoma otitis media.

Methods: A retrospective study as made of 78 patients with extracranial and intracranial complications caused by suppurative otitis media between January 1992 and December 2002 was conducted.

Results: Fifty-six of the 78 patients had one complication and the other 22 patients had two or more complications among them.
