ABSTRACT
Objective: To analyse the mental state of patients with allergic rhinitis (AR) in Chengdu. Methods: One thousand five hundred and thirty-six AR patients from Sichuan Provincial Integrated Traditional Chinese and Western Medicine Hospital, West China Hospital of Sichuan University, Affiliated Hospital of Chengdu University of Traditional Chinese Medicine, Sichuan People's Hospital, Sichuan Second Hospital of Traditional Chinese Medicine were selected from July 2013 to January 2018. Eight hundred and twenty-seven patients were screened into study group by inclusion and exclusion standards. The symptom check list 90 (SCL-90) was used to group and score the mental state of these patients according to nine classification criteria: gender, BMI, age, marital status, monthly salary, disease duration, living environment, education level and working environment. Then, the scores were compared within groups. Inter-group comparison was made between the study group and the Chinese norm, and the positive factors for psychological disorders were extracted. Four symptoms in the study group, i.e. nasal itching, sneezing, clear discharge and nasal congestion, were scored on the visual analogue scale (VAS). SPSS 19.0 software was used to carry out statistical analysis. Partial correlation analysis was performed between the positive factors and the symptom scores by multiple regression statistical method. Results: The total score of SCL-90 in the study group was 2.64±0.25, which was accorded with mild to moderate mental health impairment. There were 124 (15.0%) without mental health damage, 176 (21.3%) with mild damage, 474 (57.3%) with mild to moderate damage, 41 (5.0%) with moderate to severe damage and 12 (1.4%) with severe damage. The in-group comparison showed that the top three categories of different items were the living environment, gender and working environment. The scores of somatization, obsessive-compulsive symptoms, interpersonal sensitivity, depression, anxiety, psychosis, other (sleep, diet) and total average score of urban residents were higher than that of country residents (3.29±0.61 vs 2.65±0.50, 2.81±0.77 vs 2.05±0.38, 3.10±0.19 vs 2.49±0.67, 3.40±0.84 vs 2.49±0.70, 3.04±0.64 vs 2.33±0.51, 3.02±0.55 vs 2.40±0.77, 3.40±0.41 vs 2.52±0.77, 2.91±0.11 vs 2.29±0.40, Z value was 4.88, 5.25, 4.57, 5.91, 5.09, 4.63, 5.55, -4.55, respectively, all P<0.05). Women scored higher than man for somatization, interpersonal sensitivity, depression and others (2.66±0.51 vs 2.00±0.45, 3.37±0.47 vs 2.63±0.51, 3.44±0.57 vs 2.85±0.52, 3.47±0.36 vs 2.76±0.45, Z value was -5.10, -5.51, -4.86, -5.28, respectively, all P<0.05). The scores of somatization, interpersonal sensitivity, psychosis and other (sleep, diet) were higher in the indoor group than those in the outdoor group (3.49±0.64 vs 2.78±0.46, 3.33±0.30 vs 2.56±0.68, 3.28±0.60 vs 2.67±0.31, 3.50±0.85 vs 2.85±0.37, Z value was 5.31, 5.79, 4.89, 5.00, respectively, all P<0.05). The outdoor group scored higher on obsessive-compulsive symptoms, anxiety and hostility (3.44±0.40 vs 2.83±0.35, 3.40±0.50 vs 2.57±0.93, 3.34±0.88 vs 2.69±0.56, Z value was 4.96, 6.22, 5.08, respectively, all P<0.05). The inter-group comparison found that depression, anxiety, psychosis and other (sleep, diet) could be partially correlated with VAS scores as 4 positive factors. The results of partial correlation analysis showed that depression was positively correlated with sneezing and nasal runny discharge, anxiety was positively correlated with nasal itching and nasal obstruction, psychosis was positively correlated with nasal itching and sneezing, and other (sleep, diet) was positively correlated with nasal runny discharge and nasal obstruction. Conclusion: AR patients have mild to moderate mental health impairments, which are correlated with AR symptoms.

BACKGROUND: Two brown-like adipocytes, including classical brown adipocytes from brown adipose tissues and beige cells from white adipose tissues, regulate thermogenesis. The developmental and functional induction of brown-like cells provides a defense against obesity and associated metabolic diseases. Our previous study suggests dietary luteolin can improve diet-induced obesity and insulin resistance in mice. Here we further elucidated the action of the natural flavonoid on energy expenditure and adaptive thermogenesis. METHODS: Five-week-old male C57BL/6 mice were fed low-fat diet (LFD), high-fat diet (HFD) and HFD supplemented with 0.01% luteolin. After 12 weeks, their energy expenditure were detected using a combined indirect calorimetry system. Moreover, thermogenic program and associated molecular regulators were assessed in adipose tissues. In another independent study, even-aged mice were fed LFD and luteolin-containing LFD for 12 weeks, and their energy expenditure and thermogenic program were also investigated. Finally, differentiated primary brown and subcutaneous adipocytes were used to identify the critical participation of AMPK/PGC1α signaling in luteolin-regulated browning and thermogenesis. RESULTS: In mice fed either HFD or LFD, dietary luteolin supplement increased oxygen consumption, carbon dioxide production and respiratory exchange ratio. The enhancement in energy expenditure was accompanied by the upregulation of thermogenic genes in brown and subcutaneous adipose tissues. Meanwhile, several important AMPK/PGC1α signaling molecules were activated by dietary luteolin in the tissues. Further, luteolin treatment directly elevated thermogenic gene expressions and activated AMPK/PGC1α signaling in differentiated primary brown and subcutaneous adipocytes, whereas AMPK inhibitor Compound C reversed the efficiencies. CONCLUSIONS: Dietary luteolin activated browning and thermogenesis through an AMPK/PGC1α pathway-mediated mechanism.

AIMS: To examine and illustrate the morphological characteristics and growth kinetics of Cs-HK1, a Tolypocladium fungus, isolated from wild Cordyceps sinensis in solid and liquid cultures, and the major chemical constituents and antitumour effects of Cs-HK1 mycelium. METHODS AND RESULTS: The Cs-HK1 fungus was isolated from the fruiting body of a wild C. sinensis and identified as a Tolypocladium sp. fungus. It grew rapidly at 22-25 degrees C on a liquid medium containing glucose, yeast extract, peptone and major inorganic salts, with a specific growth rate of 1.1 day(-1), reaching a cell density of 23.0 g dw l(-1) in 7-9 days. Exopolysaccharides accumulated in the liquid culture to about 0.3 g l(-1) glucose equivalent. In comparison with natural C. sinensis, the fungal mycelium had similar contents of protein (11.7-microg) and carbohydrate (654.6-microg) but much higher contents of polysaccharide (244.2 mg vs 129.5 mg), adenosine (1116.8-microg vs 264.6 microg) and cordycepin (65.7 microg vs 20.8 microg) (per gram dry weight). Cyclosporin A, an antibiotic commonly produced by Tolypocladium sp., was also detected from the mycelium extract. The hot water extract of mycelium showed low cytotoxic effect on B16 melanoma cells in culture (about 25% inhibition) but significant antitumour effect in animal tests, causing 50% inhibition of B16 cell-induced tumour growth in mice. CONCLUSIONS: The Tolypocladium sp. fungus, Cs-HK1, can be easily cultivated by liquid fermentation. The mycelium biomass contained the major bioactive compounds of C. sinensis, and the mycelium extract had significant antitumour activity. SIGNIFICANCE AND IMPACT OF THE STUDY: The Cs-HK1 fungus may be a new and promising medicinal fungus and an effective and economical substitute of the wild C. sinensis for health care.
