Sncg, Mybpc1, and Parm1 Classify subpopulations of VIP-expressing interneurons in layers 2/3 of the somatosensory cortex.

Neocortical vasoactive intestinal polypeptide-expressing (VIP+) interneurons display highly diverse morpho-electrophysiological and molecular properties. To begin to understand the function of VIP+ interneurons in cortical circuits, they must be clearly and comprehensively classified into distinct subpopulations based on specific molecular markers. Here, we utilized patch-clamp RT-PCR (Patch-PCR) to simultaneously obtain the morpho-electric properties and mRNA profiles of 155 VIP+ interneurons in layers 2 and 3 (L2/3) of the mouse somatosensory cortex.

Prospective assessment and risk factors of sleep disturbances in total hip and knee arthroplasty based on an Enhanced Recovery After Surgery concept.

Purpose: This study aimed to examine sleep quality and risk factors associated with sleep disturbance in patients undergoing total joint arthroplasty (TJA) managed with an enhanced recovery protocol from preoperatively until 12 weeks postoperatively in order to provide suggestions for improving the prevention and treatment of sleep disturbance in these patients.

Methods: The Chinese versions of the Pittsburgh Sleep Quality Index (CPSQI) and Epworth Sleepiness Scale (CESS) were used to evaluate sleep quality. Pain was measured by a visual analog scale (VAS).

MicroRNA‑mRNA integrated analysis based on a case of well‑differentiated thyroid cancer with both metastasis and metastatic recurrence.

The incidence of well‑differentiated thyroid cancer (WDTC) is rapidly increasing. Poor survival follows distant metastasis (DM) and recurrence. In the present study, we aimed to analyze the expression alterations in different stages of WDTC and the regulatory mechanism of DM and the recurrence of DM.

Neuroserpin restores autophagy and promotes functional recovery after acute spinal cord injury in rats.

This study is to reveal the characteristics of autophagy and the effect of neuroserpin (NSP) treatment on autophagy during the process of functional recovery following spinal cord injury (SCI). After the clip compress rat model of SCI had been made, autophagy‑associated proteins, including LC3‑II, beclin‑1 and p62, were evaluated at 2, 4, 24, 72 h, and 168 h in the experimental group, and the sham group as control. Transmission electron microscopy (TEM) was further used for autophagy detection at 4 and 72 h.

Proteogenomic characterization and integrative analysis of glioblastoma multiforme.

Glioblastoma multiforme (GBM), the most aggressive and lethal primary brain tumor, is characterized by very low life expectancy. Understanding the genomic and proteogenomic characteristics of GBM is essential for devising better therapeutic approaches.Here, we performed proteomic profiling of 8 GBM and paired normal brain tissues.

Highly Variable Femoral Morphology in Osteoarthritic Chinese: Are Prostheses Today Sufficiently Suitable?

We aimed to retrospectively investigate the morphology of the resected surfaces of femurs in Chinese patients who underwent total knee arthroplasty (TKA) and to assess the suitability of contemporary femoral components. Measurements on three-dimensional reconstruction after virtual bone cutting were performed on 142 knees from Chinese TKA candidates. The anteroposterior (AP) and mediolateral (ML) dimensions, aspect ratio (ML/AP), and posterior condylar angle (PCA) were measured in the axial plane; the height and length of medial and lateral anterior condyles and the maximal width of the anterior condyles were measured in the frontal plane.

The orientation of the surgical epicondylar axis varies in varus and non-varus knees in the coronal plane.

Purpose: To investigate the orientations of the surgical epicondylar axis (SEA) of varus and non-varus knees in the coronal plane.

Methods: One-hundred and sixty-two knees from 81 Chinese patients undergoing total knee arthroplasty (TKA) were retrospectively investigated. The angle between the medial side of the femoral mechanical axis and the SEA (MA-SEA), as well as the physiological valgus angle, was measured in the coronal plane using three-dimensional reconstruction.

The effects of P-gp and CYP450 modulated by rifampicin on the steroid-induced osteonecrosis of the femoral head.

This study investigated the effects of rifampicin-modulated P-glycoprotein (P-gp) and cytochrome P450 (CYP450) activity on the development of steroid-induced osteonecrosis of the femoral head. Thirty-two rabbits were equally divided into four groups: control group, oral administration group, intramuscular injection group, and local release group, in which rifampicin-loaded artificial bone graft was implanted in the left femur cavity and blank bone graft was implanted in the right femur cavity. Dexamethasone was given 1 week after rifampicin administration.

The fate of the remaining knee(s) or hip(s) in osteoarthritic patients undergoing a primary TKA or THA.

The purpose of this study was to determine the fate of the remaining hip(s) and knee(s) following an initial total hip or knee arthroplasty in 5352 patients with idiopathic osteoarthritis who were followed for a minimum ten years (mean 17.8 ± 5.7 years).

A meta-analysis of plate fixation versus intramedullary nailing for humeral shaft fractures.

Background: There is a lack of consensus on whether intramedullary nailing (IMN) or plating is superior for humeral shaft fractures.

Methods: In this meta-analysis, we combined data from PubMed, the Excerpta Medica Database (Embase), the Cochrane Library, and the Chinese National Knowledge Infrastructure (CNKI) (all to Dec 31, 2011). Six randomized controlled trials (RCTs) and two quasi-RCTs including 384 participants were selected and assessed by use of an 11-item scale.

Population-based and family-based studies on the protein tyrosine phosphatase non-receptor 22 gene polymorphism and type 1 diabetes: a meta-analysis.

Purpose: Studies investigating the association between PTPN22 gene C1858T polymorphism and type 1 diabetes (T1D) susceptibility among Caucasian population have reported conflicting results. To investigate this inconsistency, we performed a meta-analysis of all available studies dealing with the relationship between the PTPN22 C1858T polymorphism and T1D.

Methods: Databases including PubMed, Web of Science, and EMBASE were searched to find relevant studies.

Effect of sildenafil on peripheral nerve regeneration.

In this study, we investigated whether sildenafil, a cyclic guanosine monophosphate-dependent phospodiesterase-5 inhibitor, could promote functional nerve regeneration after surgical section and repair of the sciatic nerve in rats. Nerve regeneration was studied in a rat sciatic nerve transected and repair model. The animals were randomly assigned to one of the following 3 treatment groups (n = 20/group): sildenafil-treated group 1 (5 mg/kg/d subcutaneously, for 7 days), sildenafil-treated group 2 (5 mg/kg/d subcutaneously, for 42 days), and control group given saline solution (once per day subcutaneously).

Neuroserpin upregulates in the early period of sustained spinal cord compression.

Background: Neuroserpin (NSP) is a neuroprotective factor in the situation of ischemia of a brain, such as stroke. However, it has never been reported in the spinal cord, which is part of the central nervous system (CNS).

Methods: The expression of NSP was detected using Western blotting and neuron apoptosis detected by TUNEL staining following spinal cord ischemia caused by sustained compression in rats.

Quantitative assessment of the effect of ABCA1 gene polymorphism on the risk of Alzheimer's disease.

ATP-binding cassette transporter A1 (ABCA1) is a membrane-associated protein which has attracted considerable attention as a candidate gene for Alzheimer's disease (AD) based on its function as a key factor in lipid metabolism by mediating cellular cholesterol efflux, the rate-limiting step in the production of nascent high-density lipoprotein (HDL) particles. The relationship between ABCA1 common variations (R219 K rs2230806, I883 M rs4149313 and R1587 K rs2230808) and AD has been reported in various ethnic groups; however, these studies have yielded contradictory results. To investigate this inconsistency, we performed a meta-analysis of 13 studies involving a total of 12,248 subjects to evaluate the effect of ABCA1 on genetic susceptibility for AD.

Synthetic osteogenic growth peptide promotes differentiation of human bone marrow mesenchymal stem cells to osteoblasts via RhoA/ROCK pathway.

The osteogenic growth peptide (OGP) is a naturally occurring tetradecapeptide that has attracted considerable clinical interest as a bone anabolic agent and hematopoietic stimulator. In vitro studies have demonstrated that OGP directly regulates the bone marrow mesenchymal stem cells' (BMSCs) differentiation into osteoblasts. However, the exact mechanism of this process remains unknown.
