Objective: With the application of 3D photography, our study aimed to quantify parameters of static nasolabial fold wrinkles and establish mathematic regression model between parameters of wrinkles and age, further to quantitatively evaluate the effect of rejuvenation treatment in terms of age.

Methods: From October 2016 to May 2018, 433 Chinese female volunteers, aged 25-60 years old, were enrolled in this study. Antera 3D camera was used to collect four parameters of static nasolabial fold wrinkles on the left and right sides of the volunteers, including overall size, average depth (mm), average width (mm), and maximum depth (mm).

Objective: To study the expression of T cell immunoglobulin and mucin domain 3 (Tim-3) on peripheral blood immunocytes, and the relationship between Tim-3 and the systemic inflammatory response or brain injury in patients with intracerebral hemorrhage (ICH).

Methods: According to the volume of hematoma at 12 hours after onset of ICH, 60 newly diagnosed patients with ICH were divided into the small (volume of hematoma <30 mL, 30 cases) and large (volume of hematoma ≥30 mL, 30 cases) ICH groups. The expression of Tim-3 on peripheral blood immunocytes was analyzed by flow cytometry.

Objective: Impaired immunonutritional status has disadvantageous effects on outcomes for cancer patients. Preoperative albumin-to-globulin ratio (AGR) and the prognostic nutrition index (PNI) have been used as prognostic factors in various cancers. We aimed to evaluate the clinical significance of the AGR and PNI in glioblastoma.

Objective: To discuss the significance of the radiculomuscular artery in typical variations of the distal vertebral artery (VA) from the viewpoint of microsurgical anatomy.

Methods: Some variations involving the radiculomuscular artery revealed by digital subtraction angiography (DSA) were recruited and studied together with our findings from cadaver dissections.

Results: A total of 29 variants were found in 26 patients, including 10 C‑2 vertebral origins of the posteroinferior cerebellar artery (PICA), 13 duplicated (12 patients) and 6 aberrant V3s.

Background: Nuclear factor-κB (NF-κB) plays an important role in the inflammatory response after intracerebral hemorrhage (ICH). We therefore proposed that NF-κB activation in perihematomal brain tissue might correlate with clinical outcome in patients with ICH. To confirm this, we studied clinical data of 45 patients with ICH and NF-κB activation in perihematomal brain tissue and analyzed predictors of clinical outcome as well as the predictive value of NF-κB activation.

Background: Microglia/macrophages are known to play important roles in initiating brain inflammation after spontaneous intracerebral hemorrhage (ICH). T cell immunoglobulin and mucin domain-3 (Tim-3) have been proven to play a critical part in several inflammatory diseases through regulation of both adaptive and innate immune responses. Tim-3 can be expressed by microglia/macrophages and regulates their function in the innate immune response.

Objective: To detect the expressions of matrix metalloproteinase-9(MMP-9), progesterone receptor(PR), Ki-67 and Survivin in the multiple meningiomas (MMs) and explore its genesis, diagnosis and bionomics features.

Methods: A total of 66 cases with histological sections of meningiomas retrieved from the archives of Department of Pathology of our hospital, including 30 cases of solitary meningiomas (SMs) and 36 cases MMs, were regrouped as benign, atypical and malignant by hematoxylin and eosin staining according to the World Health Organization classification of nervous system tumors. Immunohistochemistry was performed to detect the expressions of MMP-9, PR, Ki-67 and Survivin in 36 cases of MMs and 30 cases of SMs.

Objective: To explore the functions of NF2, TIMP-3 and THBS1 genes in the tumorigenesis or progression of meningiomas and analyze the values of these genes in early diagnosis, therapy and prognostic evaluation in meningiomas.

Methods: A total of 66 cases with histological sections of meningiomas, including solitary (SMs, n = 30) and multiple meningiomas (MMs, n = 36), were retrieved from our departmental archives. All cases were regrouped as benign, atypical and anaplastic (malignant) by hematoxylin & eosin staining according to the recently published WHO classification of nervous system tumors.

Background: Microvascular decompression (MVD) is a well accepted surgical treatment strategy for trigeminal neuralgia (TN) with satisfying long-term outcome. However, considerable recurrent patients need more effective management. The purpose of this study was to evaluate the effectiveness of radiofrequency thermocoagulation rhizotomy (RTR) on patients with recurrent TN after MVD.

Trigeminal neuralgia (TN) is the most common facial neuralgia, and is extremely painful. We evaluate the effectiveness of percutaneous controlled radiofrequency trigeminal rhizotomy (RFTR) assisted by a virtual reality (VR) imaging technique for idiopathic TN. A total of 2769 patients with TN underwent RFTR procedures between June 1986 and March 2007, with VR assisted guiding and electrode positioning in 26 patients from January 2006 to March 2007.

We report a patient with an intracranial epidermoid cyst associated with malignant melanoma in the cerebellopontine angle. The CT, MRI and histopathological findings showed an intracranial epidermoid cyst with an adjacent infiltrating melanoma. Immunohistochemical staining of the solid tumour was positive for the melanoma marker HMB45 and negative for GFAP and cytokeratin.
