Abstract
Depression is characterized by prominent indicators and manifestations, such as anhedonia, which refers to the inability to experience pleasure, and persistent feelings of hopelessness. In clinical practice, the primary treatment approach involves the utilization of selective serotonin reuptake inhibitors (SSRIs) and related pharmacological interventions. Nevertheless, it is crucial to recognize that these agents are associated with significant adverse effects. Traditional Chinese medicine (TCM) adopts a multifaceted approach, targeting diverse components, multiple targets, and various channels of action. TCM has potential antidepressant effects. Anomalies in adult hippocampal neurogenesis (AHN) constitute a pivotal factor in the pathology of depression, with the regulation of AHN emerging as a potential key measure to intervene in the pathogenesis and progression of this condition. This comprehensive review presented an overview of the pharmacological mechanisms underlying the antidepressant effects of active ingredients found in TCM. Through examination of recent studies, we explored how these ingredients modulated AHN. Furthermore, we critically assessed the current limitations of research in this domain and proposed novel strategies for preclinical investigation and clinical applications in the treatment of depression in future.

Fang C, Zhang J, Han J, Lei Y, Cao Z, Pan J, Pan Z, Zhang Z, Qu N, Luo H, Ma Y, Han D. Tiaogan Jiejiu Tongluo Formula attenuated alcohol-induced chronic liver injury by regulating lipid metabolism in rats. JOURNAL OF ETHNOPHARMACOLOGY 2023; 317:116838. [PMID: 37355081 DOI: 10.1016/j.jep.2023.116838] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/10/2023] [Revised: 06/15/2023] [Accepted: 06/21/2023] [Indexed: 06/26/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Tiaogan Jiejiu Tongluo Formula (TJTF), a traditional Chinese medicine formula, is modified from the well-known ancient prescription Danzhi-Xiaoyao Powder (DXP). Owing to its ability to regulate liver, strengthen spleen, detoxicating, and dredge collaterals in Chinese medicine, TJTF is usually used to treat anxiety, hypertension, alcoholic fatty liver disease in clinical application. However, the protective effect and potential molecular mechanism of TJTF on alcoholic liver injury has not fully been clarified. AIM OF THE STUDY To explore the effect of TJTF on chronic alcoholic liver injury and figure out whether its effects were due to the regulation of lipid metabolism. MATERIAL AND METHODS 75 male SD rats were divided into the following five groups, control group, EtOH group, TJTF high dose group, TJTF low dose group and silybin group. Then a chronic alcoholic liver injury model was established by increasing concentration of 56% ethanol in rats. The rats in each TJTF group were given the corresponding dose of TJTF, the rats in the silybin group were given silybin, the rats in the control group and the EtOH group were given distilled water by gavage, once a day for 8 consecutive weeks. The components of TJTF were analyzed by UPLC-Q-TOF-MS. Hematoxylin and Eosin (H&E) was used to assess the severity of liver injury. in the pathological examination. Periodic acid-Schiff (PAS) and oil red O staining were used to evaluate the degree of the liver glycogen accumulation and lipid deposition, respectively. The serum ALT, AST, T-CHO, TG, LDL-C, ADH, HDL-C, and ALDH levels as well as liver tissue GSH, MDA, and SOD levels were analyzed in rats. Immunohistochemistry and western blotting were used to detect lipid metabolism-related proteins expressed in rat liver. RESULTS TJTF significantly alleviated the chronic liver injury caused by alcohol in rats, and enhanced liver function. TJTF significantly decreased AST, ALT, ADH levels and increased ALDH level of serum, and increased GSH, SOD levels and decreased MDA level of liver tissue. In addition, TJTF significantly decreased the serum T-CHO, TG and LDL-C levels and increased HDL-C level in chronic alcoholic liver injury rats by regulating the expression of lipid metabolism associated proteins including p-LKB1, p-AMPKα, p-ACC, FAS, HMGCR, SREBP-1c, PPARα and CPT-1A. The results of western blot and immunohistochemical staining confirmed that TJTF can inhibit lipid production and promote fatty acid oxidation in the liver tissue of chronic alcoholic liver injury rats by activating the LKB1-AMPKα axis and then downregulating the protein expressions of p-ACC, FAS, HMGCR and SREBP-1c, as well as promoting the protein expressions of PPARα and CPT-1A. Meanwhile, TJTF also increased the glycogen content of liver and alleviated the liver damage. CONCLUSION According to current research, TJTF is effective in treating chronic liver damage induced by alcohol in rats. Additionally, TJTF exhibits the protective benefits by modulating LKB1-AMPKα signal axis, which in turn inhibits the synthesis of lipids and promotes the oxidation of fatty acids.

Abstract
BACKGROUND Depression is a severe mental illness that endangers human health. Depressed individuals are prone to sleep less and to the loss of appetite for food; their thinking and cognition processes, as well as mood, may even be affected. Danzhi Xiaoyao San (DXS), documented in the Internal Medicine Summary, has been used for hundreds of years in China and is widely applied traditionally to treat liver qi stagnation, liver and spleen blood deficiency, menstrual disorders, and spontaneous and night sweating. DXS can also clear heat and drain the liver. Presently, it is used frequently in the treatment of depression based on its ability to clear the liver and alleviate depression. PURPOSE To summarize clinical and preclinical studies on the antidepressant-like effects of DXS, understand the material basis and mechanisms of these effects, and offer new suggestions and methods for the clinical treatment of depression. METHODS "Danzhi Xiaoyao", "Danzhixiaoyao", "Xiaoyao", "depression" and active ingredients were entered as keywords in PubMed, Google Scholar, CNKI and WANFANG DATA databases in the search for material on DXS and its active ingredients. The PRISMA guidelines were followed in this review process. RESULTS Per clinical reports, DXS has a therapeutic effect on patients with depression but few side effects. DXS and its active ingredients allegedly produce their neuroprotective antidepressant-like effects by modulating monoamine neurotransmitter levels, inhibiting the hypothalamic-pituitary-adrenal (HPA) axis hyperfunction, reducing neuroinflammation and increasing neurotrophic factors. CONCLUSION Overall, DXS influences multiple potential mechanisms to exert its antidepressant-like effects thanks to its multicomponent character. Because depression is not caused by a single mechanism, probing the antidepressant-like effects of DXS could further help understand the pathogenesis of depression and discover new antidepressant drugs.

Abstract
Danzhi-xiaoyao-San (DZXYS), a Traditional Chinese Medicine, plays an essential role in the clinical treatment of depression, but its mechanisms in humans remain unclear. To investigate its pharmacological effects and mechanisms as an add-on therapy for depression, we conducted a double-blind, placebo-controlled trial with depressed patients receiving selective serotonin reuptake inhibitors (SSRIs). Serum and fecal samples were collected for metabolomic and microbiome analysis using UHPLC-QTRAP-MS/MS and 16S rRNA gene sequencing technologies, respectively. Depression symptoms were assessed using the 24-item Hamilton Depression Scale. We employed network pharmacology, metabolomics, and molecular docking to identify potential targets associated with DZXYS. We also examined the correlation between gut microbes and metabolites to understand how DZXYS affects the microbiota-gut-brain axis. The results showed that DZXYS combined with SSRIs was more effective than SSRIs alone in improving depression. We identified 39 differential metabolites associated with DZXYS treatment and found seven upregulated metabolic pathways. The active ingredients quercetin and luteolin were docked to targets (AVPR2, EGFR, F2, and CDK6) associated with the enriched pathways 'pancreatic cancer' and 'phospholipase D signaling pathway', which included the metabolite lysophosphatidic acid [LPA(0:0/16:0)]. Additionally, we identified 32 differential gut microbiota species related to DZXYS treatment, with Bacteroides coprophilus and Ruminococcus gnavus showing negative correlations with specific metabolites such as L-2-aminobutyric acid and LPA(0:0/16:0). Our findings indicate that DZXYS's antidepressant mechanisms involve multiple targets, pathways, and the regulation of LPA and the microbiota-gut-brain axis. These insights from our systems pharmacology analysis contribute to a better understanding of DZXYS's potential pharmacological mechanisms in depression treatment.Communicated by Ramaswamy H. Sarma.

Abstract
Objective To evaluate the efficacy and safety of transdermal drug delivery therapy for schizophrenia with anxiety symptoms. Methods A total of 80 schizophrenic patients (34 males and 56 females) with comorbid anxiety disorders were randomly assigned to the treatment group (n = 40) and the control group (n = 40) with 6 weeks of follow-up. The patients in the treatment group received the standard antipsychotic drug treatment along with transdermal drug delivery therapy. The evaluation of the patients included the Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD-17), and treatment emergent symptom scale (TESS) at baseline, 3 weeks, and 6 weeks after transdermal drug delivery therapy. The Positive and Negative Symptom Scale (PANSS) was assessed at baseline and after 6 weeks of treatment. Results After 3 and 6 weeks of treatment, the HAMA scale scores in the treatment group were lower than those in the control group (p < 0.001). However, there were no significant differences in the HAMD-17 scale scores, PANSS total scores, and subscale scores between the two groups (p > 0.05). Additionally, no significant differences in adverse effects were observed between the two groups during the intervention period (p > 0.05). After 6 weeks of penetration therapy, there was a low negative correlation between total disease duration and the change in HAMA scale score (pretreatment-posttreatment) in the treatment group. Conclusion Combined traditional Chinese medicine directed penetration therapy can improve the anxiety symptoms of patients with schizophrenia and has a safe profile.

Abstract
BACKGROUND Premenstrual dysphoric disorder (PMDD) is a common mental health challenge among women of reproductive age. Allopregnanolone (3α, 5α-THP; ALLO) mediated functional alterations of GABAA receptors (GABAA-R) are involved in PMDD pathogenesis, however, the specific mechanism remains unknown. Therefore, we investigated the role of ALLO mediated GABAA-Rα4 in the pathophysiology of PMDD. PURPOSE We determined whether the pathogenesis of PMDD is associated with ALLO mediated GABAA-Rα4 expression changes in different brain regions. METHODS Rat models of PMDD liver-qi invasion syndrome (PMDD-LIS) were established via the resident intruder paradigm. Behavioral changes of rats were assessed by aggressive behavior tests, EPM and OFT. The levels of progesterone and ALLO in serum as well as brain areas were determined by ELISA. Variations in GABAA-Rα4 levels in brain regions were assessed by immunofluorescence and RT-PCR. Medicated serum was used to interfere with rat hippocampal neurons, and changes in Cl- current were recorded through electrophysiology. RESULTS Premenstrual anxiety and irritability of PMDD-LIS patients can be simulated in PMDD-LIS rat models. Exogenous ALLO significantly improved the anxiety behaviors of PMDD-LIS rats. Changes in ALLO among different brain regions varied. GABAA-Rα4 expressions were low in the amygdala and abnormally high in the hippocampus, however, ALLO alleviated these deviations. Whole-cell patch clamp recording technique showed a weaker Cl- current intensity of PMDD-LIS rats, reduced neuroinhibitory functions and increased Cl- current intensity in the ALLO group drug serum intervention and enhanced emotional inhibition function. CONCLUSION We established that ALLO regulation of the GABAA-Rα4 subunit in the amygdala and hippocampus is involved in PMDD-LIS pathogenesis.

Abstract
Depression is a chronic mental illness with devastating effects on a person's physical and mental health. Studies have reported that food fermentation with probiotics can enrich the nutritional values of food and produce functional microorganisms that can alleviate depression and anxiety. Wheat germ is an inexpensive raw material that is rich in bioactive ingredients. For example, gamma-aminobutyric acid (GABA) is reported to have antidepressant effects. Several studies concluded that Lactobacillus plantarum is a GABA-producing bacteria and can alleviate depression. Herein, fermented wheat germs (FWGs) were used to treat stress-induced depression. FWG was prepared by fermenting wheat germs with Lactobacillus plantarum. The chronic unpredictable mild stress (CUMS) model was established in rats, and these rats were treated with FWG for four weeks to evaluate the effects of FWG in relieving depression. In addition, the study also analyzed the potential anti-depressive mechanism of FWG based on behavioral changes, physiological and biochemical index changes, and intestinal flora changes in depressed rats. The results demonstrated that FWG improved depression-like behaviors and increased neurotransmitter levels in the hippocampus of CUMS model rats. In addition, FWG effectively altered the gut microbiota structure and remodeled the gut microbiota in CUMS rats, restored neurotransmitter levels in depressed rats through the brain-gut axis, and restored amino acid metabolic functions. In conclusion, we suggest that FWG has antidepressant effects, and its potential mechanism may act by restoring the disordered brain-gut axis.

Abstract
Background Although controversial, experimental data suggest the use of propofol may be associated with neurotoxicity. The mechanisms responsible for propofol neurotoxicity in animals are not yet clear. Objective This study aimed to determine the effects of propofol on the proliferation of neural stem cells in rat hippocampus and the mechanisms underlying these effects. Methods Forty-five adult male Sprague-Dawley rats were randomly divided into 5 groups: Control (N group), intralipid (V group), 30 mg/kg propofol (Prop30 group), 60 mg/kg propofol (Prop60 group), and 120 mg/kg propofol (Prop120 group). The rats in all groups received 5, once daily intraperitoneal injections. For each of the 5 days, the N group received 6 mL/kg normal saline, the V group received 6 mL/kg fat emulsion, the Prop30 group received 30 mg/kg propofol, the Prop60 group received 60 mg/kg propofol, and the Prop120 group received 120 mg/kg propofol. Memory function was scored daily using the Morris water maze test. Immunofluorescence staining was used to histologically monitor the proliferation and differentiation of the rats' hippocampal neural stem cells, and real time quantitative polymerase chain reaction and Western blotting were used to determine the expression of Notch3, Hes1, and Hes5. Results Compared with the N group, the Prop120 group exhibited reduced learning and memory, whereas there were no significant differences for the Prop60 group. The number of β-tubulin III+ cells increased in the Prop60 group, but decreased in the Prop120 group. Compared with the N group, the relative expression of Notch3 and Hes5 increased significantly in the Prop60 group, whereas this expression decreased in the Prop120 group. Conclusions These data demonstrate that repeated, subchronic (5 days) intraperitoneal injections of 60 mg/kg propofol can effectively promote rat hippocampal neural stem cells proliferation and differentiation, and that this is likely mediated by its effects on the Notch3-Hes5 pathway.

Abstract
Background: A sharp decline in neural regeneration in patients with Alzheimer’s disease (AD) exacerbates the decline of cognition and memory. It is of great significance to screen for innovative drugs that promote endogenous neural regeneration. Cytisine N-methylene-(5,7,4′-trihydroxy)-isoflavone (LY01) is a new compound isolated from the Chinese herbal medicine Sophora alopecuroides with both isoflavone and alkaloid characteristic structures. Its pharmacological effects are worth studying.Objective: This study was designed to determine whether LY01 delays the cognitive and memory decline in the early stage of AD and whether this effect of LY01 is related to promoting neural regeneration.Methods: Eight-week-old 5×Familial Alzheimer’s Disease (5×FAD) mice were used as disease models of early AD. Three doses of LY01 administered in two courses (2 and 5 weeks) of treatment were tested. Cognition, memory, and anxiety-like behaviors in mice were evaluated by the Morris water maze, fear conditioning, and open field experiments. Regeneration of neurons in the mouse hippocampus was observed using immunofluorescence staining. The effect of LY01 on cell regeneration was also demonstrated using a series of tests on primary cultured neurons, astrocytes, and neural stem cells (NSCs). In addition, flow cytometry and transcriptome sequencing were carried out to preliminarily explored the mechanisms.Results: We found that LY01 reduced the decline of cognition and memory in the early stage of 5×FAD mice. This effect was related to the proliferation of astrocytes, the proliferation and migration of NSCs, and increases in the number of new cells and neural precursor cells in the dentate gyrus area of 5×FAD mice. This phenomenon could be observed both in 2-week-old female and 5-week-old male LY01-treated 5×FAD mice. The neuronal regeneration induced by LY01 was related to the regulation of the extracellular matrix and associated receptors, and effects on the S phase of the cell cycle.Conclusion: LY01 increases the proliferation of NSCs and astrocytes and the number of neural precursor cells in the hippocampus, resulting in neural regeneration in 5×FAD mice by acting on the extracellular matrix and associated receptors and regulating the S phase of the cell cycle. This provides a new idea for the early intervention and treatment of AD.

COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2022; 2022:1636839. [PMID: 35309844 PMCID: PMC8933099 DOI: 10.1155/2022/1636839] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/10/2022] [Revised: 01/22/2022] [Accepted: 01/27/2022] [Indexed: 11/18/2022]
Abstract
Background Rose acne is a chronic inflammatory skin disease that can cause paroxysmal flushing, persistent erythema, papules or papules on the face, and pustules, and it has a greater impact on the life of patients, so it is important to treat it. Objective To investigate the effect of Danzhi Xiaoyao Powder combined with photodynamic therapy (PDT) on the curative effect evaluation and prognosis of patients with rose acne. Patients and Methods. The clinical data of 110 rose acne patients who were treated in our hospital from January 2019 to January 2021 were selected as the subject of this retrospective study. They were divided into a control group and a treatment group according to the random residue grouping method. The new crown epidemic, loss to follow-up, etc. fell out of 5 cases in each group, and finally, 50 cases in each group were left. Among them, the control group was treated with PDT, and the treatment group was combined with Danzhi Xiaoyao Powder on the basis of the control group. Then we observe and compare the effects of skin lesion scores and clinical symptom scores and differences in clinical efficacy between the two groups. Results The comparison of the clinical symptom scores of the two groups of patients before treatment was not statistically significant (P > 0.05), while the burning score, tingling score, dryness score, and pruritus score of the treatment group after treatment were significantly different. The internal comparison after treatment was lower than before treatment, and the comparison between the treatment groups was significantly higher than the control group, which was statistically significant (P < 0.05). There was no statistically significant difference in the skin lesion scores of the two groups before treatment (P > 0.05), while the papules score, pustule score, erythema score, and telangiectasia score of the treatment group after treatment were significantly different and compared within the group. After treatment, the treatment group was significantly higher than the control group, and the comparison was statistically significant (P < 0.05). The effective rate of 98.00% in the treatment group was significantly higher than the 76.00% in the control group, and the difference was statistically significant (P < 0.05). The clinical efficacy of the two groups of patients showed that the rash, chest tightness, nausea, and diarrhea of the treatment group were significantly lower than those of the control group, and the difference was statistically significant (P < 0.05). Conclusion Danzhi Xiaoyao Powder combined with PDT to treat rose acne is effective, can quickly control inflammatory papules and inflammatory erythema, effectively improve the clinical symptoms of patients, and reduce adverse reactions.
