Adipose tissue, one type of loose connective tissue in the human body, maintains the primary task of energy storage. Adipose tissue is not only an energy reservoir but also plays a vital role as the largest endocrine organ of the whole body via releasing a variety of adipokines, which participate in many pathophysiological processes, such as energy metabolism regulation, glucose and lipid metabolism, and inflammation. Polycystic ovary syndrome (PCOS) is a disorder that mainly involves the female reproductive system, affecting women of childbearing age particularly. Insulin resistance (IR) and hyperandrogenemia (HA) have been implicated as a critical link involving the etiology and outcome of PCOS. A great deal of studies has bridged the gap between adipokines (such as Adiponectin, Chemerin, Metrnl, Apelin, Resistin, Visfatin, Leptin, Vaspin, Lipocalin 2, and Omentin) and reproductive fitness. In this review, we will focus on the adipokines’ functions on PCOS and come up with some points of view on the basis of current research.

The purpose of this study was to assess the efficacy and safety of Pelnac and split-thickness skin graft for management of complex wound with underlying bone/tendon exposure at forearm and hand. This is a prospective study, beginning from March 2013 up to May 2017. There were 13 patients, with age of 31.2 years. All of them underwent the staged Pelnac and split-thickness skin graft to manage the complex wound with bone/tendon. Postoperatively, scheduled follow-up was conducted. The average follow-up was 15 months. There were no infections, wound necrosis, hematoma, or seroma during the phase when Pelnac was applied. There was 100% “take” of the Pelnac in 12/13 patients. In 11 patients, there was complete skin graft “take”. Patients’ satisfaction for the esthetic appearance of the grafted area was 75.0 ± 8.5/100. The VSS value was 2.9 ± 2.5. Regarding the sensory recovery, the response of “normal or near normal” could be obtained in 7/13 patients, “slight loss” in 5 patients and “significant loss” in 1 case. The average DASH score was 27.2 ± 18.5, and most patients (12/13) could obtain an acceptable ability to perform the daily activities. Pelnac dermal template is a favorable alternative to flap reconstruction in the treatment of complex wound with underlying tissues exposure.

Cancer metastasis remains the most poorly understood process in cancer biology. It involves the degradation of extracellular matrix (ECM) proteins by a series of ‘tumour-associated’ proteases. Here we report the identification of a novel protease suppressor, NYD-SP8, which is located on human chromosome 19q13.2. NYD-SP8 encodes a 27 kD GPI-anchored cell surface protein, which shows structural homology to urokinase plasminogen activator receptor (uPAR). Co-immunoprecipitation experiments showed that NYD-SP8 binds to uPA/uPAR complexes and interfere with active uPA production. Overexpression of NYD-SP8 results in reducing activities of the three major classes of proteases known to be involved in ECM degradation, including uPA, matrix metalloproteinases (MMPs) and cathepsin B, leading to suppression of both in vitro and in vivo cancer cell invasion and metastasis. These data demonstrate an important role of NYD-SP8 in regulating ECM degradation, providing a novel mechanism that modulates urokinase signalling in the suppression of cancer progression.
