This study evaluated the anatomical relationship between the perforators of the DGA and the saphenous vein (SV) to review the clinical applications of the free descending genicular artery perforator (DGAP) flap for locoregional reconstruction.

Methods: Fifteen cadavers were arterially perfused with red latex and dissected.

Potential significance of high-mobility group protein box 1 in cerebrospinal fluid.

High-mobility group protein box 1 (HMGB1) is a cytokine with multiple functions (according to its subcellular location) that serves a marker of inflammation. CSF HMGB1 could be the part of pathological mechanisms that underlie the complications associated with CNS diseases. HMGB1 actively or passively released into the CSF is detected in the CSF in many diseases of the central nervous system (CNS) and thus may be useful as a biomarker.

Physical Self Matters: How the Dual Nature of Body Image Influences Smart Watch Purchase Intention.

To determine the role of physical self in body-involving consumption, we explore how body image influences purchasing intention toward hybrid products with body-involving features. In this study, we establish the dual nature of body image: specifically, body image influences intention to purchase via the perception of utilitarian value and symbolic value. Further, we find a competitive mediation in which positive body image (PBI) negatively influences purchase intention (direct effect), while PBI is positively related to purchase intention via utilitarian and symbolic value (indirect effect).

Data on DFS and OS were extracted or recalculated by meta-analysis as hazard ratios (HRs), and AEs were compared using a dominance ratio (OR).

The Chinese consensus for surgical treatment of traumatic rib fractures 2021 (C-STTRF 2021).

Rib fracture is the most common injury in chest trauma. Most of patients with rib fractures were treated conservatively, but up to 50% of patients, especially those with combined injury such as flail chest, presented chronic pain or chest wall deformities, and more than 30% had long-term disabilities, unable to retain a full-time job. In the past two decades, surgery for rib fractures has achieving good outcomes.

Tumor-derived lactate inhibit the efficacy of lenvatinib through regulating PD-L1 expression on neutrophil in hepatocellular carcinoma.

Background: Neutrophils play a controversial role in tumor development. The function of programmed cell death-1 ligand (PD-L1) neutrophils, however, may inhibit the cytotoxicity of anti-tumor immunity. In this study, we elucidate the stimulators of PD-L1 neutrophils in tumor microenvironment (TME) and explore the optimal combination to enhance the effect of lenvatinib by inhibiting PD-L1 neutrophils in hepatocellular carcinoma.

Pleiotropic Roles of CXCR4 in Wound Repair and Regeneration.

Wound healing is a multi-step process that includes multiple cellular events such as cell proliferation, cell adhesion, and chemotactic response as well as cell apoptosis. Accumulating studies have documented the significance of stromal cell-derived factor-1 (SDF-1)/C-X-C chemokine receptor 4 (CXCR4) signaling in wound repair and regeneration. However, the molecular mechanism of regeneration is not clear.

Replantation with cryopreserved parathyroid for permanent hypoparathyroidism: a case report and review of literatures.

Permanent postsurgical hypoparathyroidism is defined as insufficient parathyroid hormone (PTH) to maintain normocalcemia 6 months after surgery. It occurs mostly in reoperation for persistent or recurrent hyperparathyroidism. The treatment of long-term calcium and vitamin D supplement is burdensome and may cause iatrogenic complications.

Chemotherapy targeting cancer stem cells.

Conventional chemotherapy is the main treatment for cancer and benefits patients in the form of decreased relapse and metastasis and longer overall survival. However, as the target therapy drugs and delivery systems are not wholly precise, it also results in quite a few side effects, and is less efficient in many cancers due to the spared cancer stem cells, which are considered the reason for chemotherapy resistance, relapse, and metastasis. Conventional chemotherapy limitations and the cancer stem cell hypothesis inspired our search for a novel chemotherapy targeting cancer stem cells.

[Research and Application of iPS Cells in Blood System].

Induced pluripotent stem cells (iPS cells) were first constructed by Takahshi and et al in 2006. They converted the mouse fibroblasts into ES-like cells via viral transduction with four transcription factors (Oct4, Sox2, Klf4 and c-Myc). Since, the significant progress has been made and many researchers have succeeded in inducing iPS cells from other human somatic cells by some novel approaches, such as combining transcriptional factors and small chemicals.
