A 79-year-old patient developed severe hypoalbuminemia associated with eosinophilic peritonitis (EP) after receiving continuous ambulatory peritoneal dialysis (CAPD) for 3 years. The hypoalbuminemia and EP treated successfully with the use of prednisone acetate. This case is reported to emphasize the importance of diagnosis of EP that should be suspected when the peritoneal dialysis (PD) patient presents with severe hypoalbuminemia combined with turbid effluent along with repeated negative cultures. A short course of low-dose oral glucocorticoid may be considered in accelerating the resolution of the episode in such cases.

Carney complex (CNC) is a rare genetic disease. Here, we report a case of CNC and explore clinical manifestations and gene mutation studies of CNC. A male patient with CNC at the age of 16 yr was admitted to Affiliated Hospital of Zunyi Medical University in July, 2015. Although the patient had typical signs of Cushing's syndrome, he also presented with certain rare signs of Cushing's syndrome, such as "freckle-like" scattered spots of pigmentation on the face and around the lips. In addition, concomitant severe osteoporosis led to flattened vertebrae and the compression of corresponding levels of the spinal cord. Radiographic findings revealed adrenal nodular hyperplasia. Based on sequencing, 2 novel heterozygous mutations of the PRKAR1A gene were found. CNC was eventually diagnosed via pathologic biopsy. After 1 year of follow-up, the patient exhibited weight loss, relief of low back pain, normal blood biochemical indicators and cortisol levels at the lower limit of the normal range.

To illuminate the functional effects of allicin on rats with cognitive deficits induced by tunicamycin (TM) and the molecular mechanism of this process.
200–250 g male SD rats were divided into three groups at random: control group (n=12), TM group (5 μl, 50 μM, i.c.v, n=12), and allicin treatment group (180 mg/kg/d with chow diet, n=12). After 16 weeks of allicin treatment, the learning ability and memory were tested using novel object recognition (NOR) testing on rats with 72 hr TM treatment (5 μl, 50 μM, i.c.v); meanwhile, the variation of field excitatory postsynaptic potential (fEPSP) in the Schaffer Collateral (SC)-CA1 synapse was detected by extracellular electrophysiological recordings and the morphology of dendritic spine was observed by Golgi staining as well as detecting several synaptic plasticity-related proteins by Western blot.
The density of dendritic spine was increased significantly in allicin-treated groups and the correspondence slope of fEPSP in TM-induced cognitive deficits group was enhanced and expression of synaptophysin and glutamate receptor-1(GluR1) in hippocampal neurons was up-regulated.
The results indicate that allicin plays an important role in synaptic plasticity regulation. These finding showed that allicin could be used as a pharmacologic treatment in TM-induced cognitive deficits.

Poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP)-based gel polymer electrolytes (GPEs) with polyvinylpyrrolidone (PVP) and urea as a pore forming agent, respectively, were fabricated by phase inversion method. Physicochemical properties of the as-prepared polymer electrolytes were characterized by SEM, XRD, TG, electrochemical impedance spectroscopy (EIS) and linear sweep voltammetry (LSV). The results showed that the GPE membranes using urea as pore forming agent present a uniform surface with abundant interconnected micro-pores and possess upto 330 °C decomposition temperature; the XRD patterns indicate that adding urea into the polymer matrix can attain more amorphous areas than adding PVP; the reciprocal temperature dependence of ionic conductivity of as-prepared GPEs follows Vogel-Tamman-Fulcher relation and the ionic conductivity at room temperature is 2.212 mS cm−1 for PVP pore forming GPEs and 2.823 mS cm−1 for urea pore forming GPEs, respectively; the interfacial resistance of the Li/GPEs/Li cell using urea as pore forming agent can achieve a quick steady value of about 660 Ω cm−1 lower than that of PVP of about 760 Ω cm−1 during the same storage conditions; the electrochemical stability window of the GPEs with urea can be stable upto 5.0 V (vs. Li+/Li) at room temperature. The battery performance of the assembled Li/GPEs/LiCoO2 coin cell also showed that the cell using urea as pore forming agent in GPEs demonstrated excellent first charge/discharge rate and cycle performances. These excellent physicochemical and battery properties indicated that urea can be used as a kind of excellent pore forming agent for polymer electrolytes in the lithium-ion polymer battery.
