Adaptación y validación de la Patient Health Questionnaire for Depression and Anxiety (PHQ-4) en una muestra de quechua hablantes peruanos

Introducción: El Patient Health Questionnaire for Depression and Anxiety (PHQ-4) es una medida de autoinforme ultrabreve de síntomas depresivos y ansiosos. El PHQ-4 no ha sido adaptado ni validado en la población quechua hablante. Objetivo: Este estudio tuvo como objetivo adaptar y validar el PHQ-4 en una muestra de población peruana quechua hablante en su variante Collao de Puno-Perú. Metodología: Participaron 221 personas hablantes de quechua variante collao (promedio de edad de 31,2 años, SD = 11,7, 47,1 % hombres y 52,9 % mujeres). Se evaluó la evidencia de validez basada en la estructura interna, mediante el análisis factorial confirmatorio (CFA), la fiabilidad con el método de consistencia interna y las características de dificultad y discriminación de los ítems en base a la Teoría de Respuesta al Ítem (IRT). Resultados: Los resultados indicaron que todos los ítems del PHQ-4 son relevantes, coherentes y claros para representar adecuadamente los síntomas de ansiedad y depresión. El resultado del AFC apoyó un modelo unifactorial, donde los ítems de ansiedad y depresión conforman una sola variable latente con una fiabilidad alta. Todos los ítems del PHQ-4 presentas buenos parámetros de discriminación y los parámetros de dificultad indican que los ítems son comparativamente difíciles. Por lo tanto, se necesita una mayor presencia del rasgo latente (ansiedad y depresión) para responder las categorías de respuesta más altas. Discusión: En conclusión, la PHQ-4 presentó buenas propiedades psicométricas como una medida de detección primaria rápida, confiable y válida para personas quechuahablantes que necesitan una evaluación profunda, monitoreo de los síntomas para diagnóstico y tratamiento para la ansiedad o depresión.

Introduction: The Patient Health Questionnaire for Depression and Anxiety (PHQ-4) is an ultra-brief self-report measure of depression and anxiety symptoms. The PHQ-4 has not been adapted or validated in the Quechua-speaking population. Objective: This study aimed to adapt and validate the PHQ-4 in a sample of the Peruvian Quechua-speaking population with its Collao variant from Puno-Peru. Methods: A total of 221 Quechua speakers of the Collao variant (mean age 31.2 years, SD = 11.7, 47.1% male and 52.9% female) participated. Evidence of validity based on internal structure was evaluated using confirmatory factor analysis (CFA), reliability using the internal consistency method, and item difficulty and discrimination characteristics based on Item Response Theory (IRT). Results: The results indicated that all items of the PHQ-4 were relevant, consistent, and clear enough to adequately represent anxiety and depressive symptoms. The CFA results supported a one-factorial model, in which anxiety and depression items form a single latent variable with high reliability. All items of the PHQ-4 had good discrimination parameters, and the difficulty parameters indicated that the items were comparatively difficult. Therefore, a higher presence of the latent trait (anxiety and depression) is needed to answer higher response categories. Discussion: In conclusion, the PHQ-4 presented good psychometric properties as a rapid, reliable, and valid primary screening measure for Quechua speakers in need of in-depth assessment and symptom monitoring for the diagnosis and treatment of anxiety and depression.

Risk Factors of Depression Screened by Two-Sample Mendelian Randomization Analysis: A Systematic Review / 生物医学与环境科学（英文）

OBJECTIVE@#This study explored the potentially modifiable factors for depression and major depressive disorder (MDD) from the MR-Base database and further evaluated the associations between drug targets with MDD.@*METHODS@#We analyzed two-sample of Mendelian randomization (2SMR) using genetic variant depression ( n = 113,154) and MDD ( n = 208,811) from Genome-Wide Association Studies (GWAS). Separate calculations were performed with modifiable risk factors from MR-Base for 1,001 genomes. The MR analysis was performed by screening drug targets with MDD in the DrugBank database to explore the therapeutic targets for MDD. Inverse variance weighted (IVW), fixed-effect inverse variance weighted (FE-IVW), MR-Egger, weighted median, and weighted mode were used for complementary calculation.@*RESULTS@#The potential causal relationship between modifiable risk factors and depression contained 459 results for depression and 424 for MDD. Also, the associations between drug targets and MDD showed that SLC6A4, GRIN2A, GRIN2C, SCN10A, and IL1B expression are associated with an increased risk of depression. In contrast, ADRB1, CHRNA3, HTR3A, GSTP1, and GABRG2 genes are candidate protective factors against depression.@*CONCLUSION@#This study identified the risk factors causally associated with depression and MDD, and estimated 10 drug targets with significant impact on MDD, providing essential information for formulating strategies to prevent and treat depression.

Association and Contribution of Patient and Bereaved Family Background to Outcomes of Survivor Surveys

A secondary analysis of data from national bereavement surveys conducted in 2014, 2016, and 2018 was conducted with the aim of identifying the contribution of various patient and bereavement backgrounds to the outcomes of the Bereavement Survey. The data were evaluated in terms of structure and process of care (CES), achievement of a desirable death (GDI), complexity grief (BGQ), and depression (PHQ-9). The large data set and comprehensive analysis of bereavement survey outcomes clarified the need for adjustment of confounding variables and which variables should be adjusted for in future analyses. Overall, the contribution of the background factors examined in this study to the CES (Adj-R2=0.014) and overall satisfaction (Adj-R2=0.055) was low. The contribution of the GDI (Adj-R2=0.105) was relatively high, and that of the PHQ-9 (Max-rescaled R2=0.200) and BGQ (Max-rescaled R2=0.207) was non-negligible.

Anemia-related subjective symptoms in the general adult population in Japan / Journal of Rural Medicine

Objectives: Approximately 17% of Japanese women have hemoglobin concentrations less than 12 g/dL. Therefore, anemia prevention and early intervention are crucial public health issues in Japan. This study aimed to identify the symptoms and characteristics of anemic individuals in the general adult population by comparing survey responses of individuals with anemia and without anemia visiting blood donation centers.Materials and Methods: This cross-sectional study used self-administered questionnaires. Individuals who visited two Japanese Red Cross Society blood donation centers in Fukushima Prefecture, Japan were included. Hemoglobin levels were measured at blood donation, and the levels of 13 g/dL for men and 12 g/dL for women were defined as anemia.Results: Of the 857 individuals analyzed, 530 were men and 327 were women, of whom 19 (3.6%) and 12 (3.7%) had low hemoglobin levels, respectively. Logistic regression analysis was performed in men, and the results showed that “lightheadedness” (odds ratio [OR]=8.4) and “depressive symptoms” (OR=3.6) were significantly associated with hemoglobin levels. None of the evaluated items were significantly associated with hemoglobin levels in women.Conclusion: Among healthy Japanese men, those who exhibit lightheadedness and depressive symptoms have an increased risk of anemia. Lightheadedness and depressive symptoms may be indicative of undiagnosed anemia in men, which necessitates greater clinical attention.

Medication Ideas for Depression from Wenyang Jieyu Prescription / 中国实验方剂学杂志

Depression is a complex emotional and mental disorder. The traditional Chinese medicine （TCM） methods for treating depression mainly include soothing the liver and relieving depression. Our research team proposes that depression is caused by Yang Qi deficiency and obstructed Qi movement， which are closely related to neurological and psychological changes induced by early traumatic experiences. Therefore， we suggest that the treatment should focus on warming Yang， replenishing Qi， and promoting Qi movement and have formulated Wenyang Jieyu prescription based on Erxiantang for warming yang and Xiaoyaosan for relieving depression. The experiment with the mouse model of early trauma induced by maternal separation showed that Wenyang Jieyu prescription significantly improved the mouse activity and environmental exploration， reduced the immobility time in forced swimming and tail suspension tests， alleviated the behaviors such as aversion to darkness and fear of open space， enhanced social interaction and social cognitive abilities， altered decision-making biases， reduced depression-like behaviors， and improved the decision-making patterns. Additionally， the prescription lowered the serum level of cortisol， inhibited the cortisol surge in the dexamethasone/corticotropin-releasing hormone （Dex/CRH） test， up-regulated the expression of mineralocorticoid receptor （MR） and 11β-hydroxysteroid dehydrogenase 2 （11β-HSD2） in the hippocampus， down-regulated the expression of glucocorticoid receptor （GR） and corticotropin-releasing hormone receptor 1 （CRHR1）， inhibited the methylation of GR exon 1 and the expression of DNA methyltransferase 1 （DNMT1）， and restored the negative feedback of the hypothalamic-pituitary-adrenal （HPA） axis. Furthermore， Wenyang Jieyu prescription up-regulated the protein level of brain-derived neurotrophic factor （BDNF）， elevated the levels of postsynaptic density protein 95 （PSD95） and synaptophysin （Syn）， decreased the cell apoptosis index and B-cell lymphoma （Bcl-2）-associated X （Bax）/Bcl-2 ratio， suppressed the expression of Caspase-3， and enhanced the neuroplasticity and anti-apoptotic capacity in the hippocampus. Considering the research results， related articles， and clinical experience， we conclude that depression should be treated with liver-soothing and depression-relieving herbs， which can be supplemented with spleen-invigorating and Qi-regulating herbs to alleviate depressive symptoms. The Yang-warming and kidney-tonifying herbs can be used to eliminate the root cause and prevent relapse. Additionally， the wind-dispersing herbs can be supplemented to regulate the Qi movement throughout the body， thereby enhancing the efficacy of depression-relieving treatment.

Syndromes and Mechanisms of Depression Induced by Second Hit in Mice / 中国实验方剂学杂志

ObjectiveTo explore the syndromes and mechanisms of depression induced by maternal separation （MS） combined with chronic restraint stress （RS） in mice. MethodOn postnatal day 0 （PD0）， the offspring mice were randomized into a blank group （NC） and a modeling group. The mouse model of depression was established by MS+RS for 21 days. After removal of female mice on PD21， the modeled mice were randomized into model， Wenyang， Jieyu， Wenyang Jieyu， and fluoxetine groups， with 15 mice in each group. The sucrose preference， tail suspension， and open field tests were carried out to evaluate the anxiety and depression-like behavior in mice. Enzyme-linked immunosorbent assay was used to measure the adrenocorticotrophic hormone （ACTH） and corticosterone （CORT） levels in mouse plasma. High performance liquid chromatography-electrochemical detector was used to determine the content of monoamine neurotransmitters in the hippocampus. Real-time fluorescence quantitative polymerase chain reaction was employed to determine the mRNA levels of genes in the 5-hydroxytryptamine （5-HT） system， hypothalamic-pituitary-adrenal （HPA） axis， and brain-derived neurotrophic factor （BDNF） signaling pathway in the hippocampus. Immunohistochemistry was employed to determine the expression levels of proteins in the 5-HT system and HPA axis in the hippocampus. The Simple Western system was used to determine the protein levels of BDNF and tyrosine kinase receptor B （TrkB） in the hippocampus. ResultCompared with the NC group， the model group exhibited depression-like behavior， which was significantly relieved by Wenyang Jieyu prescription and fluoxetine. Compared with the NC group， the model group showed elevated levels of CORT and ACTH in the plasma （P<0.01）， which， however， were lowered by Wenyang Jieyu prescription and fluoxetine （P<0.05， P<0.01）. Compared with the NC group， the model group showed inhibited expression of neurotransmitters in the hippocampus （P<0.05， P<0.01）， while Wenyang Jieyu prescription and fluoxetine restored the expression of neurotransmitters （P<0.05， P<0.01）. Compared with NC group， the model group showed inhibition of the 5-HTergic nerve and abnormal activation of the HPA axis， and Wenyang Jieyu prescription and fluoxetine regulated the abnormal state of the 5-HTergic nerve and HPA axis. Compared with NC group， the modeling down-regulated the mRNA and protein levels of BDNF and TrkB in the hippocampus （P<0.05， P<0.01）， which， however， were recovered in Wenyang， Jieyu， Wenyang Jieyu， and fluoxetine groups （P<0.05， P<0.01）. ConclusionThe mouse model of depression induced by MS+RS may present the syndrome of Yang deficiency and liver depression. Wenyang Jieyu prescription may increase the content of hippocampal neurotransmitters by regulating the 5-HT system and the BDNF signaling pathway mediated by the HPA axis， thereby alleviating depression-like behavior in mice.

Modified Xiaoyaosan Alleviates Depression-like Behaviors by Regulating Activation of Hippocampal Microglia Cells in Rat Model of Juvenile Depression / 中国实验方剂学杂志

ObjectiveTo investigate the mechanism of Baihuan Xiaoyao Decoction （Xiaoyaosan added with Lilii Bulbus and Albiziae Cortex） in alleviating depression-like behaviors of juvenile rats by regulating the polarization of microglia. MethodSixty juvenile SD rats were randomized into normal control， model， fluoxetine， and low-， medium-， and high-dose （5.36， 10.71， 21.42 g·kg-1， respectively） Baihuan Xiaoyao decoction groups. The rat model of juvenile depression was established by chronic unpredictable mild stress （CUMS）. The sucrose preference test （SPT） was carried out to examine the sucrose preference of rats. Forced swimming test （FST） was carried out to measure the immobility time of rats. The open field test （OFT） was conducted to measure the total distance， the central distance， the number of horizontal crossings， and the frequency of rearing. Morris water maze （MWM） was used to measure the escape latency and the number of crossing the platform. The immunofluorescence assay was employed to detect the expression of inducible nitric oxide synthase （iNOS， the polarization marker of M1 microglia） and CD206 （the polarization marker of M2 microglia）. Real-time polymerase chain reaction was employed to determine the mRNA levels of iNOS， CD206， pro-inflammatory cytokines ［tumor necrosis factor （TNF）-α， interleukin （IL）-1β， and IL-6］ and anti-inflammatory cytokines （IL-4 and IL-10） in the hippocampus. Western blotting was employed to determine the protein levels of iNOS and CD206 in the hippocampus. The levels of IL-4 and IL-6 in the hippocampus were detected by enzyme-linked immunosorbent assay. ResultCompared with the normal control group， the model rats showed a reduction in sucrose preference （P<0.05）， an increase in immobility time （P<0.05）， decreased motor and exploratory behaviors （P<0.05）， and weakened learning and spatial memory （P<0.05）. In addition， the model rats showed up-regulated mRNA and protein levels of iNOS and mRNA levels of IL-1β， IL-6， and TNF-α （P<0.05）. Compared with the model group， Baihuan Xiaoyao decoction increased the sucrose preference value （P<0.05）， shortened the immobility time （P<0.01）， increased the motor and exploratory behaviors （P<0.05）， and improved the learning and spatial memory （P<0.01）. Furthermore， the decoction down-regulated the positive expression and protein level of iNOS， lowered the levels of TNF-α， IL-1β， and IL-6 （P<0.01）， promoted the positive expression of CD206， and elevated the levels of IL-4 and IL-10 （P<0.01） in the hippocampus of the high dose group. Moreover， the high-dose Baihuan Xiaoyao decoction group had higher sucrose preference value （P<0.01）， shorter immobility time （P<0.01）， longer central distance （P<0.01）， stronger learning and spatial memory （P<0.01）， higher positive expression and protein level of iNOS （P<0.01）， lower levels of TNF-α， IL-1β， and IL-6 （P<0.05， P<0.01）， lower positive expression and mRNA level of iNOS （P<0.05）， and higher levels of IL-4 and IL-10 （P<0.05， P<0.01） than the fluoxetine group. ConclusionBaihuan Xiaoyao decoction can improve the depression-like behavior of juvenile rats by inhibiting the M1 polarization and promoting the M2 polarization of microglia in the hippocampus.

Exploration of antidepressant effect and mechanism of icariside Ⅱ based on GABAergic nervous system / 中国药房

OBJECTIVE To explore the antidepressant effect and potential mechanism of icariside Ⅱ （ICSⅡ） based on the GABAergic nervous system. METHODS The male Kunming mice were randomly divided into a control group （group C， 10 mice） and a modeling group （50 mice）. The depression model was induced by chronic unpredictable mild stress （CUMS） method in the modeling group. After 21 days of stimulation， the rats of modeling group were randomly divided into depression model group （NS group）， positive control group [ECS group， oxalate escitalopram 15 mg/（kg·d）] and ICSⅡ low-dose， medium-dose and high-dose groups [ICSⅡ-L group， ICSⅡ-M group， ICSⅡ-H group； ICSⅡ 10， 20， 30 mg/（kg·d）]， with 10 mice in each group. Administration groups were given relevant medicine intragastrically， once a day， for 14 consecutive days. The sugar water preference rate， total exercise distance， immobility time in tail suspension and forced swimming experiments were detected in each group. The morphology of neurons and Nissl bodies in the hippocampal CA3 region were observed； the contents of γ-aminobutyric acid （GABA） and glutamic acid （Glu）， GABA/Glu ratio， and the expressions of GABAergic nervous system-related proteins （GABA A receptor α1， GABA B receptor 1， vesicular GABA transporter， glutamate decarboxylase 67， GABA membranal transporter 3） were detected in hippocampus. RESULTS Compared with group C， the sugar water preference rate and the total exercise distance significantly reduced in NS group， while the values of immobility time in the tail suspension test and forced swimming test were significantly prolonged （P＜0.05）. The morphology of neurons in the CA3 area of the hippocampus was irregular and the Nissl bodies were reduced， with a significant decrease in the number of structurally intact neurons （P＜0.05）； the content of Glu was significantly increased， while the content of GABA， GABA/Glu ratio， and the expressions of GABAergic nervous system-related proteins were significantly decreased （P＜0.05）. Compared with NS group， depression behavior in each administration group was improved， and the above indexes were mostly reversed （P＜0.05）. CONCLUSIONS ICSⅡ can improve depression behavior of depression model mice. The mechanisms may be associated with regulating the balance of GABA and Glu， increasing the synthesis， transport and release of GABA， and regulating the expressions of GABA-related receptors， so as to improve GABAergic nervous system.

Relationship between dry eye disease and physical and mental health in primary and secondary school teachers / 国际眼科杂志(Guoji Yanke Zazhi)

AIM:To evaluate the relationship between dry eye disease(DED)and physical and mental health in teachers, and to explore its mechanism and propose intervention measures.METHODS:Cross-sectional study. A total of 183 teachers from three primary and secondary schools in the urban area of Linyi City, Shandong Province were enrolled in the study. DED symptoms were quantified using the ocular surface disease index(OSDI)questionnaire. A compact version of the depression, anxiety, and stress scale(DASS-21)was used to evaluate psychological state. The relationship between potential influencing factors and DED was evaluated by independent sample t-test of quantitative variables and χ2test of classified variables. Logistic regression analysis was used for multivariate analysis to determine the influencing factors of DED. Pearson correlation coefficient was used to analyze the correlation between OSDI score and depression, anxiety and stress.RESULTS: There were 183 teachers, including 44 males(24.0%)and 139 females(76.0%), aged from 22 to 57 years, with an average age of(34.2±8.6)years. The prevalence of DED was 60.0%(109/183; 95%CI 52.4%-66.7%). The prevalence of depression was 26.2%(48/183; 95%CI 19.8%-32.7%); anxiety prevalence was 39.3%(72/183; 95%CI 32.2%-46.5%); and stress prevalence was 23.0%(42/183; 95%CI 16.8%-29.1%). The univariate analysis showed that increased age, increased working years, increased visual display terminal(VDT)application time, longer written working hours, reduced sleep hours, less alcohol consumption, and high scores of depression, anxiety and stress were all factors affecting DED(all P&#x0026;#x003C;0.05). Using depression scores as the psychological index, multivariate Logistic regression analysis showed that years of work, VDT application time, written working hours, sleep time, alcohol consumption and depression score were the influencing factors of DED(all P&#x0026;#x003C;0.05); Using anxiety scores as the psychological index, multivariate Logistic regression analysis showed that years of work, VDT application time, written working hours and stress scores were the influencing factors of DED(all P&#x0026;#x003C;0.05); Using stress scores as the psychological index, multivariate Logistic regression analysis showed that years of work, VDT application time, written working hours and stress scores were the influencing factors of DED(all P&#x0026;#x003C;0.05). OSDI scores were positively correlated with depression, anxiety, and stress scores in the DED group(P&#x0026;#x003C;0.05)and across all participants(P&#x0026;#x003C;0.05). In the severe DED group, OSDI scores were positively related to depression, anxiety, and stress scores(P&#x0026;#x003C;0.05).CONCLUSION: The prevalence of DED is high among the teachers. Alcohol consumption, reduced sleep, longer working years, longer VDT usage and longer written working hours are the influencing factors of DED. In severe DED group, DED is highly correlated with depression, anxiety, and stress. We should pay attention to teachers' DED and related physical and mental health problems, and actively prevent and make early diagnosis and treatment.

Recurrence rate of oral melanotic macule treated with Q-switched alexandrite laser versus surgical excision: a retrospective cohort study / 口腔疾病防治

Objective@#To compare the recurrence rates between 755 nm Q-switched alexandrite laser (QSAL) treatment and surgical excision of oral melanotic macules (OMM).@*Methods@#This study was reviewed and approved by the Ethics Committee, and informed consent was obtained from the patients. A retrospective cohort study was designed to collect demographic and clinical characteristics and follow-up data from patients with OMM. Patients who received QSAL or surgical excision in the Department of Oral Medicine, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine from January 2019 to August 2021 were included. The one-year recurrence rate was investigated as the primary outcome. Long-term adverse reaction rates were investigated as safety indicators. Kaplan-Meier analyses were performed to analyze the recurrence-free rates between the groups.@*Results@#A total of 57 patients were enrolled in this study. 16 patients underwent surgical excision, and 41 underwent QSAL. The baseline demographic and clinical characteristics between the groups were not significantly different. No recurrence (0%) of OMM was observed in the surgical excision group, while in the QSAL group, the macule recurred in 12 patients (29.27%). The average duration of recurrence was 6.08 months after treatment. Recurrence was not found to be associated with smoking (P = 1.000), gastrointestinal polyps (P = 1.000), longitudinal melanonychia (P = 0.187), family history (P = 0.552), treatment sessions (P = 0.567) or multiple macule lesions (P = 0.497). Compared with treatment with surgical excision, the odds ratio of recurrence for treatment with QSAL was 4.41, with a 95% confidence interval of 1.27-15.24 (P = 0.020). In the surgical excision group, 3 patients (18.75%) reported depressions and scars on the lesion, while no long-term adverse reactions (0%) were reported in the QSAL group (P = 0.019).@*Conclusion@#Compared with surgical excision, the advantage of QSAL is the low long-term adverse reaction rate, while the disadvantage is the relatively high one-year recurrence rate. It is necessary to communicate the advantages and disadvantages of the two methods with OMM patients to assist in clinical decision-making.

Exploring Central Regulatory Effect of Chaishao Liujuntang on Chronic Atrophic Gastritis Rats with Liver Depression and Spleen Deficiency Syndrome Based on Metabolomics / 中国实验方剂学杂志

ObjectiveBased on ultra performance liquid chromatography-mass spectrometry（UPLC-MS） and non-targeted metabolomics technology to discuss the central regulatory effect of Chaishao Liujuntang on chronic atrophic gastritis（CAG） rats with liver-depression and spleen-deficiency， and to look for the correlation between cerebral cortex， hypothalamus and metabolic status of gastric tissues. MethodA CAG rat model with liver-depression and spleen-deficiency was established by chemical induction， hunger and satiety disorders， chronic restraint and tail clamping stimulation， lasting for 16 weeks. Twenty-eight Wistar rats were randomly divided into a blank group of 8 rats and a model group of 20 rats. After the completion of modeling， 4 rats in the model group were taken to observe the pathological changes of gastric mucosa. The remaining model rats were randomly divided into a model group of 8 rats and a Chaishao Liujuntang group of 8 rats. Chaishao Liujuntang group rats were given 5.1 g·kg-1 by gavage， and the remaining rats were given equal volume sterilized water by gavage for 4 weeks. Macroscopic characteristics， behavioral indicators and histopathological changes of the gastric mucosa of rats in each group were observed and compared. UPLC-MS non-targeted metabolomics was used to explore the metabolic regulation effect of Chaishao Liujuntang on the cerebral cortex， hypothalamus and stomach tissues of CAG rats with liver-depression and spleen-deficiency. Pearson correlation coefficient method was used to analyze the correlation between different tissue metabolites. ResultCompared with the model group， the macroscopic characteristics of rats in Chaishao Liujuntang group were improved， such as hair color， mental state and stool properties， and the number of times of crossing and standing in the open field experiment was significantly increased， and the static time of forced swimming was significantly reduced（P<0.01）， and the gastric mucosa atrophy was reduced. The metabolic data from the cerebral cortex of rats in each group identified a total of 3 common potential biomarkers， but not enriched in pathways， 26 common potential biomarkers were identified in the hypothalamus， and the key metabolic pathways involved were mainly enriched in purine metabolism， glycerol phospholipid metabolism， D-glutamine and D-glutamic acid metabolism. Seventeen common potential biomarkers were identified in the stomach， and the key metabolic pathways involved were mainly enriched in thiamine metabolism， valine， leucine and isoleucine biosynthesis， and taurine and taurine metabolism. Correlation analysis of metabolites in different tissues revealed that multiple amino acids and their derivatives mediated metabolic connections between the cerebral cortex， hypothalamus and stomach of rats. ConclusionThe metabolic disorders in the cerebral cortex， hypothalamus and stomach of CAG rats with liver-depression and spleen-deficiency have their own characteristics， mainly manifested by changes in the content of glycerol phospholipids， fatty acids and bile acid metabolites. Moreover， Chaishao Liujuntang may play a central regulatory role in CAG rats with liver-depression and spleen-deficiency by correcting the metabolic disorders of amino acids.

Ameliorative effect and mechanism of curcumin on diabetes model rats with depression / 中国药房

OBJECTIVE To study the ameliorative effect and potential mechanism of curcumin on diabetes model rats with depression based on cAMP response element binding protein （CREB）/brain-derived neurotrophic factor （BDNF） signaling pathway. METHODS The diabetes model rat with depression was established by high fat and high sugar diet+intraperitoneal injection of streptozotocin+chronic unpredictable stress-induced depression. The successfully modeled rats were randomly divided into model group， positive control group （0.18 g/kg metformin and 1.8 mg/kg fluoxetine， gavage）， curcumin low-dose and high-dose groups （30， 60 mg/kg， gavage） and curcumin high-dose+CREB inhibitor group [60 mg/kg curcumin （gavage）+5 mg/kg CREB inhibitor 666-15 （intraperitoneal injection）]， with 12 rats in each group. Another 12 healthy rats were selected as the normal group. Each group was given a corresponding intervention for 4 weeks， the fasting blood glucose level of rats was detected， and the depression of rats was assessed. The levels of corticosterone （CORT） and inflammatory factors [tumor necrosis factor-α （TNF-α）， interleukin- 1β （IL-1β）， IL-6] in serum， and the levels of norepinephrine （NE） and 5-hydroxytryptamine （5-HT） in hippocampal tissue were determined. The pathological changes and neuronal apoptosis were observed in the hippocampal tissue of rats in each group； the expression levels of CREB， BDNF mRNA and protein in hippocampal tissue were detected. RESULTS Compared with the normal group， the hippocampal tissue of rats in the model group was severely damaged， and neurons were scattered， while the fasting blood glucose， the forced swimming immobility time， the tail suspension immobility time， serum levels of CORT， TNF-α， IL-1β and IL-6， and neuron apoptosis indexes were all increased or prolonged significantly （P＜0.05）. The levels of NE and 5-HT， the number of surviving neurons， and the expression levels of CREB and BDNF mRNA and protein in hippocampal tissue were decreased significantly （P＜0.05）. Compared with the 的model group， the damage to hippocampal tissue was relieved in the positive control group and curcumin groups， while the above indexes were improved significantly （P＜0.05）. The improvement effect of curcumin high-dose group was better than that of curcumin low-dose group （P＜0.05）. CREB inhibitor could significantly reverse the ameliorative effect of high-dose curcumin on the model rats （P＜0.05）. CONCLUSIONS Curcumin can improve the depression of diabetes model rats with depression， and relieve neuronal damage and inflammatory response， the mechanism of which may be associated with activating CREB/BDNF signaling pathway.

Association of diabetic retinopathy with anxiety and depression / 国际眼科杂志(Guoji Yanke Zazhi)

As society advances and living standards improve, there is a growing emphasis on the impact of mental health on illness and the interaction between them. Diabetes mellitus is one of the most common underlying diseases, and it is often accompanied by depression and anxiety. There are also many complications of diabetes, such as diabetic retinopathy(DR). DR is the leading cause of vision loss in diabetes. Vision loss inevitably increases anxiety and/or depression, which in turn may directly or indirectly affect the treatment or progression of patients with DR. This article reviews how to determine the anxiety and depression status of patients with DR, related assessment tools and methods, and their interaction with the treatment of DR. The interaction of anxiety-depressive states with DR treatment was also discussed. This review aims to raise awareness of the mental health of patients with DR, enhance doctor-patient communication and build doctor-patient trust, thus enhancing treatment adherence and clinical efficacy for individuals with DR and helping them to improve the quality of life.

2017 to 2021 suicidal behavior in hospitalized patients with major depression and the influencing factors / 上海预防医学

ObjectiveTo analyze the suicidal behavior in hospitalized patients with major depression and its influencing factors. MethodsA total of 1 000 patients with major depression admitted to our hospital from January 2017 to July 2021 were selected as the research subjects to investigate the status quo of suicidal behavior of the enrolled patients. According to the survey results， the patients were divided into suicidal behavior group and non-suicidal behavior group， and the related factors affecting their suicidal behavior. ResultsA total of 511 cases （51.10%） of the patients with major depression committed suicide in hospital， including 271 cases （27.10%） of suicidal ideation， 186 cases （18.60%） of attempted suicide， and 54 cases （5.40%） of suicide death. 489 patients （48.90%） did not commit suicide. Univariate analysis showed that there were significant differences in age， gender， marital status， loss of interest or pleasure， anxiety， sense of worthlessness or self-guilt， sleep status， personality， depressive episodes and paranoia between the suicidal behavior group and the non-suicidal behavior group （all P<0.05）. Logistic multifactorial regression analysis showed that age ≤28 years （OR=1.54）， female （OR=1.93）， anxiety （OR=1.61）， sense of worthlessness or self-guilt （OR=1.85） and paranoia （OR=2.15） were all independent predictors of suicidal behavior in the patients with major depression. ConclusionThe incidence of nosocomial suicide in patients with major depression is high. Early onset age， female， anxiety， sense of worthlessness or self-guilt， more depressive episodes and paranoia are independent risk predictors of suicide in patients with major depression. This finding can be used for clinical intervention to reduce the occurrence of suicide in patients.

Pharmacodynamic Substances and Action Mechanisms of Chaihu Shugansan in Antidepressant Treatment： A Review / 中国实验方剂学杂志

Depression is a kind of complex mental illness， which is mainly treated by western medicine at present， but the effect of western antidepressant drugs is not good due to the combined influence of side effects and individual differences of patients. Depression is a "stagnation syndrome" in traditional Chinese medicine， and its treatment principle is to disperse stagnated liver Qi for relieving Qi stagnation. The classic traditional Chinese medicine formula Chaihu Shugansan （CHSGS） has a long history of treating depression and demonstrates significant therapeutic efficacy. Clinically， the addition and subtraction of CHSGS is flexible， but the properties of the active ingredients are vague， and the mechanism and function are unclear. In order to elucidate the pharmacodynamic basis and antidepressant mechanism of CHSGS， this article reviews the pharmacodynamic material basis of CHSGS， clinical research and antidepressant mechanism research progress. Clinically， CHSGS can treat various types of depression such as primary depression， post-stroke depression， and postpartum depression. This article summarizes 32 main ingredients of CHSGS， among which albiflorin， ferulic acid， naringin， hesperidin， saikosaponin a， glycyrrhetinic acid， tangeretin， meranzin hydrate， nobiletin and glycyrrhizic acid are the quality markers （Q-markers） for the antidepressant effect of CHSGS. The antidepressant mechanism of CHSGS is complex， including regulating monoamine neurotransmitters， hypothalamic-pituitary-adrenal （HPA） axis， neurotrophic factors， inflammatory response， cell damage-related pathways， oxidative stress， etc. This article helps to deeply understand the pharmacodynamic basis and mechanism of CHSGS in treating depression， and provides a theoretical basis for the clinical application of CHSGS in treating depression and the development of antidepressant drugs.
