Objective To observe distribution laws and features of syndrome types of Chinese medicine (CM) in hyperlipidemia patients of Han, Uyghur, Kazakh nationalities in Xinjiang Uyghur Auton- omous Region. Methods Using cluster random sampling, 1 410 hyperlipidemia patients (18 -70 years old ) were recruited from Urumqi, Turpan, Altay, Ili, Aksu, Hetian in Xinjiang Uyghur Autonomous Re- gion. The general condition, susceptible factors, classification of blood lipids, complications, syndromes of CM, tongue figure, etc. clinical data were investigated using self-formulated Epidemiological Investiga- tion Questionnaire on Susceptible Factors in Different Nationalities of Hyperlipemia Patients in Xinjiang (abbreviated as Questionnaire thereafter). Factor analysis and cluster analysis were performed. Results Cronbach's coefficient for the 54 syndrome items in Questionnaire was 0.891, Kaiser-Meyer-Olkin (KMO) 0. 897, Sig <0.05 in Bartlett's sphericity test. Seventeen common factors were obtained using principal component analysis (PCA). Totally 54 common symptoms of hyperlipidemia were screened, which were then divided into 17 groups with 1 -6 symptoms in each group. F4 (soreness and weakness of waist and knees, sour pain in joints and muscles, body numbness, heavy body sensation, cold limbs), F5 (frequent and clear nocturia, dysuria,-dribble of urine, frequent urination at night), F10 (thirsty, no desire for water, tastelessness, hydroadipsia) , F12 (a white complexion with puffiness, hid- ing fever, hypoactive sexual desire) , and F17 (enuresis) were merged as Shen yang deficiency (SYD) ; F2 (fatigue, drowsiness, depression, spiritlessness, fatigue and disinclination to talk) and F15 (poor ap- petite) were merged as Pi-qi deficiency (PQD) ; F3 (dry mouth and dry pharynx, thirsty, propensity for water, bitter mouth, greasy mouth, stingy mouth, irritability and upset) and F16 (dark red tongue proper, greasy tongue fur) were merged as damp-heat trapped in Pi (DHTP). Results of cluster analysis showed that Pi-Shen deficiency (PSD) was most often seen in hyperlipidemia, and main syndrome types were sequenced from high to low as Pi-Shen deficiency type (46. 2%, 652/1 410) , blockage of cardiac vessels type ( 31. 1% , 438/1 410 ), phlegm and blood stasis internal resistance type ( 13. 3% , 187/1 410), Pi-deficiency induced damp abundance type (8. 3%, 123/1 410), Gan-Shen yin deficiency type (0. 7%, 10/1 410). Conclusions Deficiency syndrome was dominant in hyperlipidemia patients of Xinjiang Uyghur Autonomous Region. Phlegm turbidity, damp heat, and etc. were often complicated. The complex situation was manifested to be involved in multiple organs, qi-blood-fluid mixed disease.

The molecular identification of sortilin, also called neurotensin receptor-3, from three different biochemical approaches already predicted the involvement of the protein in numerous biological and cellular functions. The first important observation was that sortilin is synthesized as a precursor that is converted to a mature protein after cleavage by the protein convertase furin in late Golgi compartments. This maturation leads to the formation of a 44 amino acid peptide, the propeptide (PE). The release of this peptide when matured sortilin reached the plasma membrane remained to be demonstrated. Sortilin has been also shown to be shedded by matrix metalloproteases releasing a large extracellular fragment identified as soluble sortilin. Therefore, sortilin has been shown to interact with several proteins and receptors confirming its role in the sorting of cellular components to the plasma membrane and/or to the lysosomal pathway. Interestingly, sortilin physically interacts with the two pore domain potassium channel TREK-1 and the PE as well as its synthetic analog spadin is able to block the activation of TREK-1 highlighting their role in the depression pathology. The present review describes the advance of research that led to these results and how both the soluble form of sortilin and the sortilin-derived PE have been detected in human serum and whose levels are affected in patients with major depressive disorder (MDD). The use of spadin as an antidepressant and the further role of soluble sortilin and of sortilin-derived PE as potential biomarkers during depression statement and/or remission of the pathology are considered and discussed in this review.

Major depression can be triggered by stressful events that promote deregulation of the hypothalamic-pituitary-adrenal axis response and, in some circumstances, persistent elevation of circulating glucocorticoid levels. Animal models are widely used to investigate the mechanisms responsible for the etiology and treatment of major depression. However, to mimic the dysfunction of the hypothalamic-pituitary-adrenal axis in rodents, animals should be exposed to sustained physical and psychological stressful situations. These animal models of depression are labor intensive and impact individual animals differently. Aiming to add evidence for a new acute neuroendocrine model of depression, male and female mice were treated with a single administration of dexamethasone, and behavioral effects were evaluated in the presence and absence of the antidepressants nortriptyline and venlafaxine. Male and female Swiss mice were treated with dexamethasone (0.07 mg/kg, subcutaneously) and the mouse behavior was assessed in the tail suspension and open field tests at 4 h, 24 h, and 7 days after administration. Dexamethasone induced depressogenic-like states in both sexes at 4 and 24 h after injection. Additionally, acute dexamethasone increased latency to body fur licking, thus corroborating the depressive-like behavior. The treatment with nortriptyline and venlafaxine (both at 30 mg/kg, intraperitoneally) blocked dexamethasone-induced increase in the immobility time and the latency to self-care. In conclusion, the present findings suggest that a single administration of dexamethasone induces depressive-like states in male and female mice, and these behavioral alterations are counteracted by conventional antidepressants. Ultimately, these data provide new evidence for an acute neuroendocrine model of depression. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

This one-year longitudinal study examined trait emotional intelligence as a predictor of Internet gaming disorder (IGD). To date, only cross-sectional research has been conducted to test the protective effects of emotional intelligence against IGD tendency. Based on the Interaction of Person-Affect-Cognition-Execution (I-PACE) model, this study aimed to address the research gap by examining not only the direct effects of trait emotional intelligence, but also its indirect effects (via depressive symptoms and coping flexibility) on IGD, with both a cross-sectional and longitudinal design. The participants were 282 Chinese university students (mean age = 20.47; 39.4% males) who voluntarily completed an anonymous questionnaire at both baseline (W1) and one-year follow-up (W2). Path analysis results revealed that trait emotional intelligence had a protective but indirect effect on IGD tendency in both our cross-sectional and longitudinal data. Depression was found to have a significant, full mediating effect on the relationship between: (i) trait emotional intelligence and IGD tendency (W2) and (ii) coping flexibility and IGD tendency (W2), after adjusting for IGD tendency at the baseline (W1). Gender invariance of the path coefficient was also observed in the prospective model. This study provided longitudinal evidence to support the I-PACE model. Interventions should address both IGD and depressive symptoms, and school-based workshops to increase emotional intelligence and coping flexibility are also recommended.

Problematic smartphone use (PSU) is related to psychopathology symptoms, such as depression and anxiety. However, less is known about how responses to and coping with psychopathology correlate with PSU. We conducted a web survey of 286 American college students, querying depression and anxiety symptoms, rumination (a coping process to avoid negative emotion), PSU, and expectancies about smartphone use for mood alleviation. We conducted latent class analysis (LCA) of PSU symptom ratings, finding support for two latent subgroups of participants, involving mild and severe PSU, especially distinguished by severity of withdrawal symptoms. Rumination and negative smartphone use expectancies (i.e., to reduce distress) positively related to the more symptomatic PSU class. Results are discussed in context of the I-PACE theoretical model of problematic internet use (PIU). We emphasize the importance of response variables in I-PACE, such as internet-related cognitive bias and coping, over background psychopathology variables in influencing PIU and PSU.

Brain-derived neurotrophic factor (BDNF) is involved in pathophysiological mechanisms in neuropsychiatric diseases, including depression, anxiety, and schizophrenia (SZ), as well as neurodegenerative diseases like Parkinson's disease (PD) and Alzheimer's disease (AD). An imbalance or insufficient pro-brain-derived neurotrophic factor (proBDNF) transformation into mature BDNF (mBDNF) is potentially critical to the disease pathogenesis by impairing neuronal plasticity as suggested by results from many studies. Thus, promoting proBDNF transformation into mBDNF is therefore hypothesized as beneficial for the treatment of neuropsychiatric and neurodegenerative diseases. ProBDNF is proteolytically cleaved into the mBDNF by intracellular furin/proprotein convertases and extracellular proteases (plasmin/matrix metallopeptidases). This article reviews the mechanisms of the conversion of proBDNF to mBDNF and the research status of intracellular/extracellular proteolytic proteases for neuropsychiatric and neurodegenerative disorders.

An outbreak of salmonellosis occurred in a group of 7 long-nosed fur seals Arctocephalus forsteri undergoing rehabilitation after being found injured and malnourished on beaches along the northern New South Wales and southern Queensland coasts of Australia. Three of the 7 individuals developed clinical disease and died within 3 d. Clinical signs included profuse diarrhea, vomiting, depression, and lethargy. Salmonella enterica subsp. enterica serovar Kentucky (S. Kentucky) was cultured from 2 of the 3 deceased animals. The other 4 animals showed similar signs and recovered following treatment. S. Kentucky (antigenic formula 8,20:i:z6) was isolated from the survivors and tissues recovered from post-mortem samples of deceased animals. The bacterium was susceptible to cephalothin and sulfamethoxazole/trimethoprim and resistant to amoxicillin-clavulanate, ampicillin/amoxicillin, tetracycline, and enrofloxacin. This organism has the potential to cause disease in aquatic wildlife, as well as posing a zoonotic threat to people who utilise the aquatic environment.
