Aquaculture research has focused on polysaccharides as they are among the most promising new-generation immunostimulant used to control aquatic diseases. The aim of this study was to investigate the immunomodulatory effects of fermented wheat bran polysaccharides (FWBPs) on juvenile common carp (Cyprinus carpio). Carps were fed different FWBP amounts (0%, 0.1%, 0.2%, and 0.4%) for 8 weeks and then their skin mucus and serum immune parameters, hepatopancreas antioxidant indicators, and immune-related gene expression in the intestines, kidneys, and spleen were measured. The skin mucus IgM levels significantly increased in 0.1% FWBP group, but decreased in 0.4% FWBP group. The skin mucus protease and the serum alkaline phosphatase activities increased significantly in the 0.2%, 0.1%, and 0.4% FWBP groups, respectively. The serum total Ig levels increased noticeably in the 0.1% and 0.2% FWBP groups. The highest and lowest serum lysozyme activities were observed in the 0.1% and 0.4% FWBP groups, respectively. The hepatopancreatic total superoxide dismutase activity was higher in the 0.1% FWBP group than in the control. The malondialdehyde levels decreased significantly in the 0.2% and 0.4% groups. The intestinal mRNA levels of the LZM-C and IL-10 genes were significantly higher in the 0.2% than in the 0.4% FWBP group; TNF-α was significantly upregulated in the 0.1% group. The gene expression in the kidneys did not differ significantly among the treatments, except for a significant increase in the IL-10 expression in the 0.1% treatment. Significantly elevated expression of LZM-C in 0.2% group and IL-10 in 0.1% group was observed in the spleens. TNF-α and IL-1β were significantly downregulated in the 0.4% group. These results suggest that FWBPs could be used as immunostimulant feed additives in common carp cultures. [ABSTRACT FROM AUTHOR]

Coilia nasus is influenced by various external pressures during spawning migration and these anadromous transitions can lead to specific gut microbiome characteristics that affecting the host biological process. Therefore, the purpose of this study was to determine the variations of components and functions in the gut prokaryotic microbiome during spawning migration as well as the key factors that triggered the changes. The gut microbiome in C. nasus was mainly consisted of Proteobacteria, Bacteroidetes, Firmicutes, Deinococcus-Thermus and Fusobacteria via 16S rRNA Gene Amplicon Sequencing. The relative abundance of Acinetobacter and Clostridium increased, while Corynebacterium, Actinomyces, Bacillus, Klebsiella and Ochrobactrum decreased after entering freshwater, indicated the preference of C. nasus gut microbial members transferred from seawater to freshwater. Additionally, the proportion of Firmicutes significantly decreased and then increased, as well as the arise of some soil bacteria in gut, corresponding to the phenomenon that C. nasus are fasting during the upstream process and refeeding after entering the spawning grounds. The function prediction of gut microbiome was also consistent with the above results. The present study generally demonstrated the gut microbiome dynamics and the significant correlation between the gut microbiome and salinity and feeding behavior in the spawning migration of C. nasus.

Objective: To summarize and critically assess the inhibitory effects of Chinese herbal medicine (CHM) on tumor volume and tumor weight for the treatment of osteosarcoma (OS) in mouse models. Methods: PubMed, Embase, Web of Science, China Knowledge Resource Integrated Database (CNKI), Wanfang Database, VIP Database, and Chinese BioMedical (CBM) were searched since their inception dates to March 10, 2016. Two reviewers independently selected the controlled studies estimating effects of CHM on mouse OS by administration in vivo. A pair-wise meta-analysis was performed. Twenty-five studies with adequate randomization were included in the systematic review. Results: CHM may significantly inhibit OS growth in mice, as assessed using the tumor weight [20 studies, n=443; 290 for CHM and 153 for the control: pooled mean difference (MD)=-2.90; 95% confidence interval (Cl): −3.50 to −2.31: P<0.01], tumor volume (16 studies, n=382; 257 for CHM and 125 for the control; pooled MD =−2.57; 95% Cl: −3.33 to −1.80; P<0.01) and tumor growth inhibition rate. Conclusion: CHM could significantly inhibit the growth of OS in mouse models, which might be supportive for the design of preclinical and clinical trials in future. [ABSTRACT FROM AUTHOR]

Objective: To investigate the impact of Qing'e Pill (青娥丸, QEP) on the cancellous bone microstructure and its effect on the level of β-catenin in a mouse model of postmenopausal osteoporosis. Methods: Ninety-six 8-week-old specific pathogen free C57BL/6 mice were randomly divided into 4 groups (24/group): sham, ovariectomised osteoporosis model, oestradiol-treated, and QEP-treated groups. Three months after surgery, the third lumbar vertebra and left femur of the animals were dissected and scanned using micro-computed tomography (micro-CT) to acquire three-dimensional (3D) parameters of their cancellous bone microstructure. The impact of ovariectomy, the effect of oestradiol and QEP intervention on cancellous bone microstructure, and the expression of β-catenin were evaluated. Results: The oestradioland the QEP-treated groups exhibited a significant increase in the bone volume fraction, trabecular number, trabecular thickneßs, bone surface to bone volume ratio (BS/BV), and β-catenin expression compared with those of the model group (P <0.05). In contrast, the structure model index, trabecular separation, and BS/BV were significantly decreased compared with those of the ovariectomised osteoporosis model group (P <0.05). No differences were observed in the above parameters between animals of the QEP- and oestradiol-treated groups. Conclusions: The increased β-catenin expression may be the mechanism underlying QEP's improvement of the cancellous bone microstructure in ovariectomised mice. Our findings provide a scientific rationale for using QEP as a dietary supplement to prevent bone loss in postmenopausal women. [ABSTRACT FROM AUTHOR]

- Abstract
To date, only one case of post-traumatic endophthalmitis caused by Scedosporium dehoogii has been reported, but its contamination or colonization might not be precluded due to the absence of pathogenic isolation and/or pathological examination. We report the first case to our knowledge of S. dehoogii-induced subcutaneous scedosporiosis in a psoriatic patient. A 58-year-old man with 5-year history of psoriasis vulgaris and immunosuppressant therapy developed pyrexia and multiple subcutaneous abscesses on both knees. Direct microscopy of the yellowish pus showed masses of bright green short spores. Skin biopsy revealed some branched septate hyphae within the granuloma. Two aspirated pus specimens collected at a 1-week interval produced white cottony colonies on Sabouraud dextrose agar. Bacterial cultures of one blood and two purulent samples were negative, and fungal culture of blood sample was not performed. The isolate was identified as S. dehoogii using β-tubulin phylogeny and species-specific PCR with primer MSDE1/MSA2. Without addition of antifungal treatment, subcutaneous lesions disappeared spontaneously after immunosuppressant withdrawal and no relapse occurred during 64-month follow-up. The spontaneous recovery may result from immune reconstitution following immunosuppressant discontinuation. [ABSTRACT FROM AUTHOR]

Objectives: To observe the regulation of Chinese herbal medicine, Modifified Qing'e Pill (加味青娥丸, MQEP), on the expression of adiponectin, bone morphogenetic protein 2 (BMP2), osteoprotegerin (OPG) and other potentially relevant risk factors in patients with nontraumatic osteonecrosis of the femoral head (ONFH). Methods: A total of 96 patients with nontraumatic ONFH were unequal randomly divided into treatment group (60 cases) and control group (36 cases). The treatment group were treated with MQEP while the control group were treated with simulated pills. Both groups were given caltrate D. Six months were taken as a treatment course. Patients were followed up every 2 months. The levels of plasma adiponectin, BMP2, OPG, von Willebrand factor (vWF), von Willebrand factor cleaving protease (vWF-cp), plasminogen activator inhibitor 1 (PAI-1), tissue plasminogen activator (tPA), C-reactive protein (CRP), blood rheology, bone mineral density (BMD) of the femoral head and Harris Hip Score were measured before and after treatment. Results: After 6 months of treatment, compared with the control group, patients in the treatment group had signifificantly higher adiponectin and BMP2 levels ( P<0.01 and P=0.013, respectively), lower vWF, PAI-1 and CRP levels ( P=0.019, P<0.01 and P<0.01, respectively), and lower blood rheology parameters. BMD of the femoral neck, triangle area and Harris Hip Score in the treatment group were signifificantly higher than those in the control group. Moreover, plasma adiponectin showed a positive association with BMP2 ( r=0.231, P=0.003) and a negative association with PAI-1 ( r=-0.159, P<0.05). Conclusion: MQEP may play a protective role against nontraumatic ONFH by increasing the expression of adiponectin, regulating bone metabolism and improving the hypercoagulation state, which may provide an experimental base for its clinical effects.

- Abstract
Trichophyton interdigitale is generally deemed as an anamorph of Arthroderma vanbreuseghemii based on internal transcribed spacer (ITS) sequencing, but recently their anamorph/teleomorph connection should be cautioned based on β-tubulin phylogeny. We report three siblings and one consulting doctor who developed kerion and tinea corporis after contact with domestic rabbits. Seven same strains were isolated from four patients and three regions of a sick rabbit. The ITS and D1/D2 sequences of our isolate were 99 % homologous to A. Vanbreuseghemii, while β-tubulin sequence was 100 % identical to T. interdigitale. Our isolate was identified as T. interdigitale based on maximum likelihood analysis of β-tubulin. Random amplified polymorphic DNA revealed that the band patterns of five isolated strains and another rabbit-derived strain WCH023 were identical for OPF-03 and OPF-12. Skin lesions of all patients resolved completely for 2- to 6-week therapy of oral terbinafine and topical 1 % bifonazole or 1 % terbinafine cream. This study demonstrates that T. interdigitale of rabbit origin can cause various types of human dermatophytosis by mild scratch. Terbinafine may be the first choice for dermatophytosis caused by T. interdigitale. [ABSTRACT FROM AUTHOR]

- Abstract
Chromoblastomycosis and phaeohyphomycosis represent two poles of a disease spectrum caused by melanized fungi. Veronaea botryosa belongs to a small genus of saprobic fungi that occasionally cause human infections. To date, 11 cases of V. botryosa-induced cutaneous phaeohyphomycosis have been actually reported since 1990 after exclusion of 2 duplicated cases. We report the first case to our knowledge of cutaneous chromoblastomycosis caused by V. botryosa in a patient with pemphigus vulgaris. A 61-year-old man with 5-year history of pemphigus vulgaris and long-term treatment of corticosteroids and immunosuppressive agents developed multiple nodules on the dorsum of right wrist and hand after wrist trauma. Skin biopsy showed numerous brown muriform cells and a few septate hyphae in the tissue. Veronaea botryosa was isolated from the biopsy samples and then identified based on morphologic observation and DNA sequencing. The patient underwent immediate withdrawal of cyclophosphamide and gradual decrease in prednisone. Skin lesions healed after 5-month itraconazole therapy with an interval of 1-month terbinafine and one cycle of liquid nitrogen cryotherapy. Our results demonstrate that V. botryosa could induce both chromoblastomycosis and phaeohyphomycosis. Combined use of itraconazole and cryotherapy may be preferable to treat this infection.

- Abstract
Serum sclerostin is positively associated with serum 25 hydroxyvitamin D concentration. Our preliminary studies confirmed that Qing'e formula (QEF) could effectively increase serum 25 hydroxyvitamin D concentration in patients with postmenopausal osteoporosis (PMOP), but the effect of supplementation with QEF on serum sclerostin is unknown. This study investigated the effects of supplementation of QEF on serum sclerostin levels in patients with PMOP. Totally 120 outpatients and inpatients with PMOP treated in our hospital between January and October 2012 were randomly divided into QEF+calcium group, alfacalcidol+calcium group, and placebo+calcium group ( n=40 each), with a follow-up period of 2 years. The serum levels of sclerostin, 25 hydroxyvitamin D, and bone turnover markers (β-CTX, N-MID and T-PINP) at baseline and at the 6th month, 1st year, 1.5th year, and 2nd year after treatment were measured. The results showed that the levels of circulating sclerostin were increased significantly at the 6th month after treatment in QEF+calcium group and alfacalcidol+calcium group as compared with placebo+calcium group ( P<0.05), but there was no significant difference between the former two groups ( P>0.05). The levels of β-CTX, N-MID and T-PINP in serum were decreased in both QEF+calcium group and alfacalcidol+calcium group at the 6th month after treatment, without significant difference between the two groups ( P>0.05). But the levels were significantly lower than that in placebo+calcium group ( P<0.05). These results suggest that the mechanism by which QEF modulates bone metabolism in patients with PMOP might be related with the effect of QEF in increasing sclerostin expression. Our findings provide a scientific rationale for using QEF as an effective drug to prevent bone loss in PMOP. [ABSTRACT FROM AUTHOR]

- Abstract
Wnt signaling plays an important role in the bone development and remodeling. The Wnt antagonist Dkk-1 is a potent inhibitor of bone formation. The aims of this study were firstly to compare the serum Dkk-1 levels in postmenopausal osteoporosis patients with age-matched healthy controls, and secondly, to assess the possible relationship between Dkk-1 and β-catenin, sclerostin, or bone turnover markers [CTX, PINP, N-MID-OT and 25(OH)D] in the setting of postmenopausal osteoporosis. A total of 350 patients with postmenopausal osteoporosis and 150 age-matched healthy controls were enrolled, and the serum levels of Dkk-1, β-catenin, sclerostin, OPG, and RANKL were detected by ELISA, and bone turnover markers [CTX, PINP, N-MID-OT and 25(OH)D] were measured by Roche electrochemiluminescence system in two groups. Serum Dkk-1 levels were significantly higher in postmenopausal osteoporosis group than in control group ( P<0.001). Univariate analyses revealed that serum Dkk-1 levels were weakly negatively correlated to β-catenin ( r=−0.161, P=0.003) and OPG ( r=−0.106, P=0.047), while multiple regression analysis showed a negative correlation between serum Dkk-1 levels with β-catenin (β=−0.165, P=0.009) and BMD (β=−0.139, P=0.027), and a positive correlation between serum Dkk-1 levels and CTX (β=0.122, P=0.040) in postmenopausal osteoporosis group. No similar correlations ware observed in control group. The results provided evidence for the role of Dkk-1 in bone metabolism and demonstrated the link of Dkk-1 and Wnt/β-catenin in some ways.

- Abstract
The pathogenicity of Trichosporon dermatis isolated from skin lesions of a patient has been examined in mice. Balb/c mice were treated with two intraperitoneal injections of 100 mg/kg cyclophosphamide on days 4 and 1 and one subcutaneous injection of 10 mg/kg dexamethasone on day 1 pre-inoculation, and then challenged with 0.2 ml T. dermatis inoculum (1 × 10 CFU/ml) by topical application on an abrasive wound in the dermabrasive group and by hypodermic injection in the subcutaneous group. In the intravenous group, 0.2 ml of high (1 × 10 CFU/ml) or low (1 × 10CFU/ml) inoculum was injected into the tail vein. Histopathology and inverse fungal culture were performed on the skin lesion and viscera, and renal fungal burden was also determined. Inoculated sites developed localized infections after dermabrasive and subcutaneous challenge in all mice, but the maximum area of skin lesions, and number of positive cultures from the lesions, were higher for immunocompromised mice. In the intravenous group, all immunocompetent animals survived during the four-week period, whereas 100 and 70% of immunocompromised animals died by 3 and 5 days in the high and low-inoculum groups, respectively. The incidence of disseminated infection and the renal fungal burden of immunocompromised mice were higher than those of immunocompetent mice. Our results demonstrate that subcutaneous and intravenous injection of T. dermatis can successfully establish cutaneous and systemic infection models in immunocompromised mice, with the kidney and lung being most susceptible.
