ABSTRACT
Objective@#The economic hardship brought by the coronavirus disease-2019 (COVID-2019) pandemic has caused mental health problems among people of different socioeconomic status (SES). As social support helps to buffer these problems, we investigated the association between job loss related to COVID-19 and depression, anxiety, and suicidal thoughts; the differences in the effects according to SES; and the mediating effects of social support. @*Methods@#The effects of COVID-19-related job loss on depression, anxiety, and suicidal thoughts among 1,364 people were investigated through semi-structured and self-administered questionnaires: Patient Health Questionnaire–9, General Anxiety Disorder–7, and the Functional Social Support Questionnaire. Logistic regression and subgroup analyses were performed to assess the association between job loss and mental health status, and the moderating effects of income and educational levels. Moreover, the mediating effects of perceived social support on the association between job loss and depression, anxiety, and suicidal thoughts were analyzed. @*Results@#COVID-19-related job loss increased the risk of depression and suicidal thoughts. Adults with lower income and education level were at higher risk of depression, anxiety, and suicidal thoughts; perceived social support level had significant mediating effects on the association between job loss and depression/anxiety; and income level had significant moderating effects on this mediating pathway. @*Conclusion@#COVID-19-related job loss were likely to be significantly associated with negative mental health outcomes, especially among individuals with low income and education levels. As social support had buffering effects on such outcomes, related government policies in cooperation with the governance of communities and stakeholders must be prepared.
ABSTRACT
AIM: To investigate the effect of modified Chufeng Yisun Decoction on ocular surface inflammation after pterygium surgery.METHODS: A total of 60 patients(60 eyes)with primary pterygium who underwent pterygium surgery were randomly divided into control group and study group, with 30 cases(30 eyes)in each group. In the control group, patients were treated with pranoprofen eye drops, tobramycin dexamethasone eye drops, and deproteinized calf blood extract eye gel after the surgery. In the study group, patients were treated by oral modified Chufeng Yisun Decoction in addition to the treatments in the control group. The changes of ocular irritation symptoms, ocular inflammatory signs, tear interleukin 6(IL-6)levels, and tear ferning test(TFT)of patients in the two groups were assessed.RESULTS: The visual analogue scale(VAS)in patients of both groups was significantly lower at 2d and 1wk after the surgery than that at 1d after the surgery(all P<0.01), and the VAS of the study group was significantly better than that of the control group at 2d and 1wk after surgery(P<0.01). The ocular signs integrals(OSI)and TFT results of both groups at 1wk were significantly lower than those at 1d after the surgery(all P<0.01), and the OSI and TFT were also lower in the study group than in the control group at 1wk after the surgery(all P<0.01). In addition, the concentration of tear IL-6 in both groups was significantly lower at 1wk after the surgery than 1d after the surgery(all P<0.01), and it was also significantly lower in the study group than in the control group at 1wk after the surgery(P<0.05).CONCLUSION: The combination of Chufeng Yisun Decoction and conventional treatment of western has a better effect on controlling ocular surface inflammation after pterygium surgery.
ABSTRACT
Objective@#A growing body of evidence reports on the effect of different types of childhood abuse on the structural and functional architecture of the brain. In the present study, we aimed to investigate the differences in cortical thickness according to specific types of childhood abuse between patients with major depressive disorder (MDD) and healthy controls (HCs). @*Methods@#A total of 61 patients with MDD and 98 HCs were included in this study. All participants underwent T1-weighted magnetic resonance imaging, and the occurrence of childhood abuse was assessed using the Childhood Trauma Questionnaire. We investigated the association between whole-brain cortical thickness and exposure to any type of childhood abuse and specific type of childhood abuse in the total sample using the FreeSurfer software. @*Results@#No significant difference was reported in the cortical thickness between the MDD and HC groups nor between the “any abuse” and “no abuse” groups. Compared to no exposure to childhood sexual abuse (CSA), exposure to CSA was significantly associated with cortical thinning in the left rostral middle frontal gyrus (p=0.00020), left (p=0.00240), right fusiform gyri (p=0.00599), and right supramarginal gyrus (p=0.00679). @*Conclusion@#Exposure to CSA may lead to cortical thinning of the dorsolateral prefrontal cortex, which is deeply involved in emotion regulation, to a greater extent than other types of childhood abuse.
ABSTRACT
Zuojinwan originated from Danxi′s Experiential Therapy （《丹溪心法》） in the Yuan dynasty. It is a representative prescription for the treatment of liver fire invading stomach syndrome， and is also one of the typical prescriptions of the anti-adjuvant method of traditional Chinese medicine （TCM）. In this paper， the method of bibliometrics was used to systematically sort out the ancient books of Zuojinwan， and 729 relevant literature data were obtained. After certain retrieval and screening， 57 ancient books of TCM were finally obtained. The statistics and analysis were carried out from the aspects of prescription source， historical evolution， composition， functions， evolution of prescription meaning， prescription dose， and preparation and usage of Zuojinwan. It was found that Zuojinwan was composed of Coptis chinensis rhizoma and Euodia rutaecarpa fructus in a ratio of 6∶1. It was mainly used for the treatment of liver fire invading stomach syndrome. The symptoms included pain in chest and hypochondrium， vomiting and bitter mouth， noisy acid-swallowing， red tongue coating yellow， and pulse string number. Later medical records recorded that Zuojinwan was mostly consistent with the original prescription. It mainly treated various diseases caused by liver fire， including left by liver fire， including left hypochondriac pain， swallowing acid and vomiting acid， tendon hernia and lump， epigastric pain， bitter mouth pulse string， head pain， diarrhea， gonorrhea， cold and hot， abdominal pain， alcohol wet yellowing， silence of oral dysentery and so on. There was little controversy in the analysis of relevant prescriptions. In the past dynasties， pills was mainly used， which was consistent with the original prescription. In modern times， it is mainly water flooding for pills or steamed cakes for pills， warm boiling water to serve 6 g， taking 2-3 g per time， the history is basically the same. In this paper， through the excavation， collation and systematic analysis of the ancient literature of TCM that recorded Zuojinwan， we hope to provide the literature basis for the development， inheritance and utilization of this famous classical formulas.
ABSTRACT
In the clinical practice of rheumatic immune diseases in traditional Chinese medicine （TCM），it`s still unclear about the dominant diseases and breakthrough points. It`s urgent missions to formulate TCM diagnosis and treatment guidelines widely recognized and integrated by traditional Chinese medicine and Western medicine. In order to clarify the dominant diseases and breakthrough points in rheumatism，China association of Chinese medicine initiated a research group covering experts in the field of rheumatism of traditional Chinese medicine and Western medicine. Based on questionnaire survey and on-site discussion，experts had reached the following consensus. Evidence-based medicine research using modern medical methods and scientific methods should be carried out to provide objective clinical evidences. "Four mutuality" were put forward as the basis for the work of integrated traditional Chinese and Western medicine，that is the mutual communication using the exchangeable context，the mutual explanation using common theories，the mutual certification using common standards，and the mutual integration using common means. Key works should focus on solving refractory rheumatism in the future. In terms of dominant diseases and breakthrough points，this paper introduces 21 breakthrough points in 6 dominant diseases，including rheumatoid arthritis，ankylosing spondylitis，Sjogren's syndrome，hyperuricemia and gout，systemic lupus erythematosus and fibromyalgia syndrome. Advice on this discussion can provide valuable references for developing the treatment scheme of rheumatism with TCM and integrated Chinese and Western medicine and clinical practice and scientific research.
ABSTRACT
Trait impulsivity is a known risk factor for suicidality, and the prefrontal cortex plays a key role in impulsivity and its regulation. However, the relationship between trait impulsivity, neural basis, and suicidality has been inconsistent. Therefore, this study aimed to explore the relationship between impulsivity and its structural correlates (prefrontal gray matter volume), suicidal ideation, and actual suicide attempts. A total of 87 individuals with major depressive disorder participated in study, and the gray matter volume of the prefrontal regions was extracted from T1 images based on region of interest masks. The variables for the mediation models were selected based on correlation analysis and tested for their ability to predict suicide attempts, with impulsivity and suicidal ideation as the mediation variables and gray matter volume as the independent variable. A significant correlation was observed between suicidal ideation and the left dorsolateral prefrontal cortex and right dorsomedial prefrontal cortex. The dual-mediation model revealed a significant indirect relationship between gray matter volume in both regions and suicide attempts mediated by motor impulsivity and suicidal ideation. The counterintuitive positive relationship between gray matter volume and suicidality was also discussed.
ABSTRACT
Objective To investigate the effect of Yipi Yanggan prescription on the malignant transformation of liver stem cells in liver precancerous lesion induced by diethylnitrosamine (DEN) and its possible molecular mechanism. Methods A total of 35 male Sprague-Dawley rats were randomly divided into normal control group (blank group), DEN model group (model group), DEN+Yipi Yanggan prescription group (Yipi Yanggan prescription group), and DEN+Hugan tablet group (Hugan tablet group), with 5 rats in the blank group and 10 rats in the other three groups. Intraperitoneal injection of DEN was performed to establish a model of liver precancerous lesion, the rats were sacrificed after 16 weeks of administration. The serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and albumin (Alb) were measured; liver tissue was collected to observe the changes in size and appearance and calculate liver weight ratio (liver index); HE staining and Sirius Red staining were used to observe the pathological and morphological changes of rat liver tissue; immunohistochemistry was used to measure the expression of OV6 and glutathione S-transferase-Pi (GST-Pi); RT-PCR was used to measure the mRNA expression of EpCAM, CD133, and CD90, and Western blot was used to measure the protein expression of PI3K, Akt, and mTOR and their phosphorylation level. A one-way analysis of variance was used for comparison between multiple groups, and the least significant difference t -test was used for further comparison between two groups. Results Compared with the model group, the Yipi Yanggan prescription group and the Hugan tablet group had significant improvements in liver pathology and morphology, significant reductions in liver index and the levels of ALT and AST, and a significant increase in the level of Alb (all P < 0.05), as well as significant reductions in the protein expression levels of GST-Pi, OV6, p-PI3K, p-Akt, and p-mTOR and the mRNA expression levels of EpCAM, CD133, and CD90 (all P < 0.05). Compared with the Hugan tablet group, the Yipi Yanggan prescription group showed a more significant protective effect on the liver, with significant reductions in liver index and the levels of ALT and AST, and a significant increase in the level of Alb (all P < 0.05), as well as significant reductions in the protein expression levels of GST-Pi, OV6, p-PI3K, p-Akt, and p-mTOR and the mRNA expression levels of EpCAM, CD133, and CD90 (all P < 0.05). Conclusion Yipi Yanggan prescription can improve liver precancerous lesion induced by DEN in rats by inhibiting the malignant transformation of liver stem cells, and its mechanism of action may be associated with the PI3K/Akt/mTOR signaling pathway.
ABSTRACT
Late-life depression (LLD) is one of the most common psychiatric disorders. However, LLD is often undetected or inadequately treated by clinicians. This review summarizes the recent research on pharmacotherapy for LLD, updates information on monotherapy using recommended antidepressants, and discusses the clinical features and diagnostic criteria for LLD.Current Concepts: The diagnostic criteria for depression in both elderly and young adults are identical. Clinical features of the elderly with depression more likely include more comorbid medical conditions and cognitive impairment than those of young adults. Depression in the elderly tends to have a more chronic course with frequent recurrences or relapses.Discussion and Conclusion: The current pharmacological treatment guidelines for LLD recommend the use of selective serotonin reuptake inhibitor (SSRI), serotonin-norepinephrine reuptake inhibitor, bupropion, mirtazapine, and vortioxetine as first-line medications. SSRIs, among them, are recommended first because they present fewer serious adverse effects and more clinical evidence than those of other antidepressants. Before starting antidepressant treatment for LLD, clinicians should consider patients’ comorbid medical conditions, drug interactions, possible adverse effects of antidepressants, and polypharmacy. The starting dose of antidepressants for elderly patients should be half of that prescribed for young adults to minimize the adverse effects; however, most elderly patients need the same antidepressant doses as that prescribed for young patients. After remission, a 1-year maintenance treatment is required to prevent recurrence or relapse of LLD.
ABSTRACT
Objective@#Although bipolar II disorder (BD II) is not simply a mitigated form of bipolar I disorder (BD I), their neurobiological differences have not been elucidated. The present study aimed to explore cortical thickness (CT) and surface area (SA) in patients with BD I and BD II and healthy controls (HCs) to investigate the shared and unique neurobiological mechanisms of BD subtypes. @*Methods@#We enrolled 30 and 44 patients with BD I and BD II, respectively, and 100 HCs. We evaluated CT and SA using FreeSurfer and estimated differences in CT and SA among the three groups (BD I vs. BD II vs. HC). We adjusted for age, sex, educational level, and intracranial volume as confounding factors. @*Results@#We found widespread cortical thinning in the bilateral frontal, temporal, and occipital regions; cingulate gyrus; and insula in patients with BD. Alterations in SA, including increased SA of the pars triangularis and decreased SA of the insula, were noted in patients with BD. Overall, we found BD II patients demonstrated decreased SA in the right long insula compared to BD I patients. @*Conclusion@#Our results suggest that decreased SA in the right long insula is crucial for differentiating BD subtypes.
ABSTRACT
Objective@#Studies have been conducted to identify brain structural alterations related to high impulsivity in psychiatric populations. However, research on healthy subjects is relatively less extensive. Therefore, we aimed to investigate the correlation between the cortical thickness of whole brain regions and the impulsivity level in a healthy population. @*Methods@#We included 100 healthy participants aged 19–65 years. Their T1-weighted magnetic resonance images and the 23-item Barratt Impulsiveness Scale (BIS) score were obtained. The patients were divided into high and low impulsivity groups according to the 75th percentile score of the BIS in the sample. The thickness of each cortical region was calculated using the FreeSurfer, and the difference in cortical thickness of the whole brain between the high and low impulsivity groups was analyzed using one-way analysis of covariance including age, sex, education level, and total intracranial cavity volume as covariates. @*Results@#The high impulsivity group showed significant cortical thinning in the left pars opercularis. The cortical thickness of the left pars opercularis significantly correlated negatively with the total, attention, and motor scores of the BIS scale. @*Conclusion@#Our findings suggest that prefrontal cortex thinning may play an important role in the development of high impulsivity in healthy adults.
ABSTRACT
This narrative review discusses how peripheral and central inflammation processes affect brain function and structure in depression, and reports on recent peripheral inflammatory marker-based functional and structural magnetic resonance imaging (MRI) studies from the perspective of neural-circuit dysfunction in depression. Chronic stress stimulates the activity of microglial cells, which increases the production of pro-inflammatory cytokines in the brain. In addition, microglial activation promotes a shift from the synthesis of serotonin to the synthesis of neurotoxic metabolites of the kynurenine pathway, which induces glutamatemediated excitotoxicity in neurons. Furthermore, the region specificity of microglial activation is hypothesized to contribute to the vulnerability of specific brain regions in the depressionrelated neural circuits to inflammation-mediated brain injury. MRI studies are increasingly investigating how the blood levels of inflammatory markers such as C-reactive protein, interleukin (IL)-1β, IL-6, and tumor necrosis factor-α are associated with functional and structural neuroimaging markers in depression. Functional MRI studies have found that peripheral inflammatory markers are associated with aberrant activation patterns and altered functional connectivity in neural circuits involved in emotion regulation, reward processing, and cognitive control in depression. Structural MRI studies have suggested that peripheral inflammatory markers are related to reduced cortical gray matter and subcortical volumes, cortical thinning, and decreased integrity of white matter tracts within depression-related neural circuits. These neuroimaging findings may improve our understanding of the relationships between neuroinflammatory processes at the molecular level and macroscale in vivo neuralcircuit dysfunction in depression.

ABSTRACT
Objective@#Advances in surface-based morphometric methods have allowed researchers to separate cortical volume into cortical thickness (CTh) and surface area (SA). Although CTh alterations in major depressive disorder (MDD) have been observed in numerous studies, few studies have described significant SA alterations. Our study aimed to measure patients’ SAs and to compare it with their CTh to examine whether SA exhibits alteration patterns that differ from those of CTh in drug-naïve patients with MDD. @*Methods@#A total of 71 drug-naïve MDD patients and 111 healthy controls underwent structural magnetic resonance imaging, and SA and CTh were analyzed between the groups. @*Results@#We found a smaller SA in the left superior occipital gyrus (L-SOG) in drug-naïve patients with MDD. In the CTh analysis, the bilateral fusiform gyrus, left middle occipital gyrus, left temporal superior gyrus, and right posterior cingulate showed thinner cortices in patients with MDD, while the CTh of the bilateral SOG, right straight gyrus, right posterior cingulate, and left lingual gyrus were increased. @*Conclusion@#Compared with the bilateral occipito-temporal changes in CTh, SA alterations in patients with MDD were confined to the L-SOG. These findings may improve our understanding of the neurobiological mechanisms of SA alteration in relation to MDD.

From the point of view of the volatility, the comprehensive score of Jiuwei Qianghuo pills is higher than that of granules and oral liquid.
ABSTRACT
Objectives@#The aim of this study is to investigate the association between secondhand smoke (SHS) exposure and depressive symptoms among Korean adults. This study also explored the mediating role of self-rated health (SRH) and perceived usual stress (PUS) in the association between depressive symptoms, suicidal ideation and SHS exposure. @*Methods@#Data from the Korea National Health and Nutrition Examination Surveys (KNHANES) in 2014 and 2016 was analyzed for 10539 participants aged 19 years or older. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated in the logistic regression analysis with adjustment for the potential confounding factors. We also adopted the mediation analysis method by Hayes and Preacher. @*Results@#After adjusting for the potential confounding factors, SHS at home and at public places were associated with depressive symptoms and suicidal ideation among non-smokers. After adjusting for the potential confounding factors, SHS at home and at public places was associated with depressive symptoms and suicidal ideation among non-smokers. Meanwhile SHS at workplaces was associated with depressive symptoms among former smokers and with suicidal ideation among current smokers. There was an additive effect of SHS on depressive symptoms only among non-smokers. SRH mediated the association between SHS and depressive symptoms and suicidal ideation among non-smokers. We did not observe any significant mediating effect of SRH nor PUS on the association between SHS and depressive symptoms among former and current smokers. @*Conclusions@#SHS may be associated with depressive symptoms and suicidal ideation in Korean adults. Our study elucidated how SHS interacted with depressive symptoms among non-smokers through the mediation by SRH.

ABSTRACT
Hepatocellular carcinoma (HCC) is a leading cause of cancer-related death worldwide and hepatitis B virus (HBV) infection is one of most important risk factors for HCC. The development of HBV-related HCC involves a complex interaction between host and virus, and related risk factors include HBV viral load, HBeAg, and host susceptibility. Screening methods for HCC include radiological examination such as ultrasound and serological markers such as α-fetoprotein, and protein induced by vitamin K antagonist-II and alpha-fetoprotein (AFP) variants may help with the diagnosis of AFP-negative HCC. Appropriate measures such as HBV vaccination and antiviral therapy can help to prevent HCC. The long-term goal of antiviral therapy for chronic hepatitis B is to reduce complications such as liver cirrhosis and HCC. nucleos(t)ide analogues can effectively inhibit replication of virus, but they cannot eradicate covalently closed circular DNA in the nucleus of hepatocytes. There is still an urgent need for a cure for hepatitis B. This article reviews the epidemiology, risk factors, screening methods, and preventive strategies for HBV-related HCC.
