The vertebrate central nervous system (CNS) is the most complex system of the body. The CNS, especially the brain, is generally regarded as immune-privileged. However, the specialized immune strategies in the brain and how immune cells, specifically macrophages in the brain, respond to virus invasion remain poorly understood.

Introduction: The role of functional magnetic resonance imaging (fMRI) findings in investigation of working memory (WM) deficit in schizophrenia patients is still debatable. The aim of the study was to investigate the role of fMRI findings of the frontal and parietal brain activity in investigation of WM deficit in schizophrenia patients.

Material And Methods: We used Medline, Embase, and the Cochrane Database to conduct a comprehensive search up to January 2023.

Obsessive-compulsive symptoms are frequently observed in various psychiatric disorders, including obsessive-compulsive disorder, schizophrenia, depression, and anxiety. However, the underlying anatomical basis of these symptoms remains unclear. In this study, we aimed to investigate the mechanism of schizophrenia with obsessive-compulsive symptoms by using diffusion tensor imaging (DTI)-based structural brain connectivity analysis to assess the network differences between patients with obsessive-compulsive disorder (OCD), patients with schizophrenia showing obsessive-compulsive symptoms (SCH), schizophrenia patients with obsessive-compulsive symptoms due to clozapine (LDP), and healthy controls (CN).

Major depressive disorder (MDD) is a severe and devastating condition. However, the anatomical basis behind the affective symptoms, cognitive symptoms, and somatic-vegetative symptoms of MDD is still unknown. To explore the mechanism behind the depressive symptoms in MDD, we used diffusion tensor imaging (DTI)-based structural brain connectivity analysis to investigate the network difference between MDD patients and healthy controls (CN), and to explore the association between network metrics and patients' clinical symptoms.

Objective: This study reports clinical characteristic of moderate-severe obsessive-compulsive disorder (OCD) among school students in China.

Methods: We examined 153 patients for the distribution of OCD symptoms using the Yale-Brown Obsessive Compulsive Scale Symptoms Checklist, the severity of anxiety and depression symptoms using the Hamilton Anxiety Scale and the Hamilton Depression Scale-24, respectively, and impairment in learning, family and social functions using the Pediatric Quality of Life Enjoyment and Satisfaction Questionnaire.

Results: The number of total OCD, obsession and compulsion symptoms was 6.

Objective: A 29-year-old male from Guizhou, China, had been suffering from obsessive–compulsive disorder since graduation from junior high school at 14 years. He was afraid of putting glass substances in his mouth. His main symptoms were repetitive thoughts, inquiries and examinations for more than 6 hours a day.

Background: Major depressive disorder (MDD) is highly heterogeneous in pathogenesis and manifestations. Further classification may help characterize its heterogeneity. We previously have shown differential metabolomic profiles of traditional Chinese medicine (TCM) diagnostic subtypes of MDD.

Aim: Transcutaneous electrical acupoint stimulation (TEAS) has the potential to alleviate post-traumatic stress disorder (PTSD). The purpose of this study was to determine whether adding TEAS to sertraline or cognitive behavioral therapy (CBT) could improve the anti-PTSD efficacy.

Methods: In this randomized controlled trial, 240 PTSD patients (60 in each group) were assigned to receive simulated TEAS combined with sertraline (group A) or with CBT (group B), active TEAS combined with CBT (group C), or active TEAS combined with CBT plus sertraline (group D) for 12 weeks.

Article Synopsis
  • Major depressive disorder (MDD) is complex and can be classified into different subtypes. This study aimed to see if metabolomic variables could distinguish between these types in relation to traditional Chinese medicine (TCM).
  • A total of 50 patients with recurrent depression were analyzed, split into two TCM subtypes (Liver Qi Stagnation and Heart and Spleen Deficiency), with healthy volunteers as controls, using gas chromatography-mass spectrometry to assess their metabolic profiles.
  • The findings revealed distinct metabolomic profiles for each TCM subtype compared to healthy controls, with specific differences in amino acids and energy metabolism, indicating that the LQS subtype may be linked to unique pathophysiological processes and potential biomarkers for tailored antidepressant therapies

Background: Transcutaneous electrical acupoint stimulation (TEAS) is thought to have potential to treat obsessive-compulsive disorder (OCD).

Objective: The purpose of this study was to determine whether adding TEAS to cognitive behavioral therapy (CBT) and clomipramine would improve the efficacy of these conventional treatments in OCD.

Methods: In this randomized controlled trial, 360 OCD patients were assigned to receive TEAS combined with CBT plus clomipramine (Group A, n = 120), TEAS combined with CBT plus placebo (Group B, n = 120), and simulated (placebo) TEAS combined with CBT plus clomipramine (Group C, n = 120) for 12 weeks.

Objective: To evaluate the hypoglycemic effect of flavonoids from Prinsepia utilis Royle in alloxan-induced diabetic mice.

Methods: The hypoglycemic effects were investigated in alloxan-induced diabetic mice after oral administration of 300 mg/kg of flavonoids from Prinsepia utilis Royle for four weeks. The blood glucose (GLU), total cholesterol (TC), triglyceride (TG), very low density lipoprotein cholesterol (VLDL-C), alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood urea nitrogen (BUN) and body weight of mice were determined.
