Objective: To investigate the findings of adult moyamoya disease (MD) of different types on plain CT, brain perfusion CT (CTP) and brain CT angiography (CTA). Materials and methods: A total of 48 patients with ischemic MD and hemorrhagic MD were recruited into present study, and findings were collected from plain CT, CTP and CTA. Results: The incidence of watershed or cortex stroke in ischemic MD (55.6% and 38.9%) was higher than in hemorrhagic MD (0%). The incidence of ventricle or basal ganglia stroke in hemorrhagic MD (40.0%, 43.3%) was higher than in ischemic MD (0%, 5.6%). CTP showed hypoperfusion in 11 patients, hyperperfusion in 12 and normal perfusion in 25. Ischemic MD patients were more likely to present hypoperfusion (61.1%; normal perfusion: 22.2%; hyperperfusion: 16.7%). Hemorrhagic MD patients were more likely to present normal perfusion (70%; hyperperfusion: 30%; hypoperfusion: 0%). The incidence of grade II MD in ischemic MD (27.8%) was higher than in hemorrhagic MD (6.7%). The incidences of grade IV and V MD in hemorrhagic MD (33.3% and 16.7%) were higher than in ischemic MD (16.7% and 11.0%). Conclusion: Hemorrhagic MD is dominant in adults with MD and stroke of these patients mainly occurs at the intraventricular space and basal ganglia. Ischemic MD in adults is characterized by hypoperfusion and hemorrhagic MD by normal perfusion on CTP. MD in adults is usually classified as grade II, III or IV on CTA. © 2015 E-Century Publishing Corporation. All rights reserved.

Coxsackievirus B3 (CVB3) is a causative agent of viral myocarditis, pancreatitis, and meningitis in humans. Although the susceptibility of CVB3-induced acute pancreatitis is age-dependent, the underlying mechanisms remain unclear. Here we identified the host factor Golgi matrix protein 130 (GM130) as a novel target of CVB3 during CVB3-induced acute pancreatitis. The viral protein VP1 interacted with GM130, disrupted GM130-GRASP65 complexes, and caused GM130 degradation, which may lead to disruption of the Golgi ribbon and development of acute pancreatitis in mice. Interestingly, the expression level of GM130 in mouse pancreas was age-dependent, which was nicely correlated with the age-associated susceptibility of CVB3-induced acute pancreatitis. Furthermore, interference RNA-mediated knockdown of GM130 significantly reduced CVB3 replication in HeLa cells. Taken together, the study identified GM130 as a novel target of CVB3, which may implicate in the pathogenesis of CVB3-induced acute pancreatitis.

Dietary or nutrient patterns represent the combined effects of foods or nutrients, and elucidate efficaciously the impact of diet on diseases. Because the pharmacotherapy on attention deficit hyperactivity disorder (ADHD) was reported be associated with certain side effects, and the etiology of ADHD is multifactorial, this study investigated the association of dietary and nutrient patterns with the risk of ADHD. We conducted a case-control study with 592 Chinese children including ADHD (n = 296) and non-ADHD (n = 296) aged 6–14 years old, matched by age and sex. Dietary and nutrient patterns were identified using factor analysis and a food frequency questionnaire. Blood essential elements levels were measured using atomic absorption spectrometry. A fish-white meat dietary pattern rich in shellfish, deep water fish, white meat, freshwater fish, organ meat and fungi and algae was inversely associated with ADHD (p = 0.006). Further analysis found that a mineral-protein nutrient pattern rich in zinc, protein, phosphorus, selenium, calcium and riboflavin was inversely associated with ADHD (p = 0.014). Additionally, the blood zinc was also negatively related to ADHD (p = 0.003). In conclusion, the fish-white meat dietary pattern and mineral-protein nutrient pattern may have beneficial effects on ADHD in Chinese children, and blood zinc may be helpful in distinguishing ADHD in Chinese children. © 2016 by the authors; licensee MDPI, Basel, Switzerland.

Objective: To investigate the effects of flavonoids from semen cuscutae (FSCs) on the hippocampal-hypothalamic-pituitary-ovarian sex hormone receptors in female rats exposed to psychological stress and to explore the related mechanism. Materials and Methods: Flavonoids were obtained from semen cuscutae using solvent extraction and polyamide column chromatography. Sound, light, and electricity were combined into psychological stress for endocrine dysfunction model establishment in female rats. The effects of FSCs on estrogen receptor (ER) in the hippocampus, hypothalamus, and pituitaries, as well as on follicle-stimulating hormone receptor (FSHR) and luteinizing hormone receptor (LHR) in the ovaries of the psychologically stressed rats were quantitatively analyzed using immunohistochemistry and image analysis. Results: FSCs increased ER expression in the hippocampus, hypothalamus, and pituitaries, as well as LHR expression in the ovaries, but had no effect on FSHR expression in the ovaries. Conclusion: FSCs are an effective medicine in the treatment of ovarian endocrine dysfunction in psychologically stressed rats.

The increasing incidence of vulvovaginal candidiasis (VVC) and the emergence of fluconazole resistance are an indisputable fact. However, little information is available regarding the correlation between fluconazole resistance in vaginal Candida albicans and the expression of drug efflux pump genes. In this study, we investigated the species distribution, fluconazole susceptibility profiles and the mechanisms of fluconazole resistance in Candida strains. In total, 785 clinical Candida isolates were collected from patients with VVC. C. albicans was the most frequently isolated species (n = 529) followed by C. glabrata (n = 164) and C. krusei (n = 57). Of all Candida isolates, 4.7% were resistant to fluconazole. We randomly selected 18 fluconazole-resistant isolates of C. albicans to evaluate the expression of CDR1, CDR2, MDR1 and FLU1 genes. Compared with fluconazole-susceptible C. albicans isolates, CDR1 gene expression displayed 3.16-fold relative increase, which was statistically significant. CDR2, MDR1 and FLU1 overexpression was observed in several fluconazole-resistant C. albicans isolates, but statistical significance was not achieved. These results demonstrate a high frequency of non-albicans species (32.6%); however, C. albicans is the most common Candida species implicated in vaginitis, and this strain displays considerable fluconazole resistance. Meanwhile, our study further indicates that fluconazole resistance in C. albicans may correlate with CDR1 gene overexpression. © 2014 Blackwell Verlag GmbH.

Fluconazole resistance of Candida albicans has been reported to be the result of one or more specific point mutations in ERG11 gene. In this study, we amplified and sequenced the entire ERG11 coding sequence of 72 isolates of C. albicans to search for possible mutations. Twenty-seven silent mutations and 14 missense mutations were identified. While the mutations K342R and V437I were found as single-amino-acid changes in Erg11p, other mutations were detected simultaneously in individual isolates. Several different clinical isolates had the same pattern of multiple amino acid alternations: (1) A114S with Y257H was identified in 11 resistant and 3 susceptible dose-dependent isolates without any other silent mutation and may be associated with resistance; (2) Y132H combined with G450E was identified in two fluconazole-resistant isolates and is known to contribute to resistance; and (3) the coexistence of D116E, K128T, Y132H, and G465S was first described in five reduced-susceptibility isolates, but the correlation of this pattern with resistance is still uncertain. These data indicate that multiple amino acid substitutions in Erg11p were found frequently in clinical isolates and may be associated with fluconazole resistance. © 2013, Mary Ann Liebert, Inc. 2013.

To investigate changes in serum complement, immunoglobulins and lymphocyte subsets in children with common and severe bronchial pneumonia, and the role of immune function testing in bronchial pneumonia.Twenty children with common bronchial pneumonia, 20 with severe bronchial pneumonia and 20 healthy children (as controls) were enrolled in this study. Immunization rate scattering turbidimetry and six-color flow cytometry were used to detect changes in serum levels of IgA, IgG and IgM, complement C3 and C4 and CD3(+), CD4(+), CD8(+), CD16(+), CD56(+) and CD19(+) cells.The IgA levels of children with common and severe pneumonia were significantly lower than in the control group (P<0.05). The IgG level of children with severe pneumonia was significantly lower than in the control group (P<0.05). There were no significant differences in the levels of IgM and complement C3 and C4 between the two pneumonia groups and the control group (P>0.05). Compared with the controls, the children with severe pneumonia showed significantly lower CD4(+) and CD3(+) counts (P<0.05) and a significantly higher CD19(+) count (P<0.05), and the CD16(+) and CD56(+) counts of children with severe pneumonia were significantly lower than in the controls and in children with common pneumonia (P<0.05). There were no differences in CD8(+) count and CD4(+)/CD8(+) ratio between the two pneumonia groups and the control group (P>0.05).Immune dysfunction exists in children with bronchial pneumonia, especially those with severe pneumonia. Changes in immune function are correlated with the severity of pneumonia. Immune function testing in children with pneumonia has important clinical significance.

Type 1 diabetes (T1D) is an autoimmune disease that has strong contribution of genetic factors to its etiology. We aimed to assess the genetic association between non-HLA genes and T1D in a Chinese case-control cohort recruited from multiple centers consisting of 364 patients with T1D and 719 unrelated healthy children. We genotyped 55 single nucleotide polymorphisms (SNP) markers located in 16 non-HLA genes (VTCN1, PTPN22, CTLA4, SUMO4, CD274, IL2RA, INS, DHCR7, ERBB3, VDR, CYP27B1, CD69, CD276, PTPN2, UBASH3A, and IL2RB) using SNaPshot multiple single-base extension methods. After multivariate analysis and correction for multiple comparisons, we identified the SNP rs2292239 in ERBB3 gene were significantly associated with T1D. The frequency of the major G allele was significantly decreased in patients with T1D (68.8% in T1D vs 77.3% in controls, OR 0.65, 95% CI 0.53-0.79, P=0.02), and the minor allele T was associated with an increased risk of T1D (OR 1.55, 95% CI 1.26-1.90, P=0.02). Our haplotype analysis confirmed that rs2292239 was the primary T1D association locus in our current investigation. These results indicated that the ERBB3-rs2292239 was the primary T1D association locus among the investigated 55 SNPs in 16 non-HLA genes in Chinese Han population.

This study investigated prognostic factors for early recovery of coronary artery lesion (CAL) in children with Kawasaki disease (KD).Patients hospitalized for KD were enrolled less than 2wk from the onset of illness and divided into two groups: KD with CAL and KD without CAL. The CAL group was further divided into two subgroups according to the degree of CAL: mild (n = 31) and moderate/severe (n = 6) and further divided into two subgroups according to the age: younger than 1 y (n = 9) and older than 1 y (n = 28). Lectin pathway-related factors MASP-1, CD59, and C5b-9 were measured, along with C-reactive protein, white blood cell counts, erythrocyte sedimentation rate, and platelet count. Patients were followed up for 3 mo. Correlation between the measured factors and the length of time of recovery from CAL was analyzed.Plasma concentrations of MASP-1 in the CAL group were significantly lower than those without CAL. MASP-1 and gender positively correlated with the recovery time of CAL. There was no difference in MASP-1 between mild and moderate/severe CAL. At 3-mo follow-up, there was a positive correlation between plasma MASP-1 concentration and recovery time of the patients with CAL older than 1 y.Plasma MASP-1 concentration at the early stage of KD is predictive of length of time of recovery from CAL.
