  • The Unfolded Protein Response (UPR) serves as a critical cellular mechanism dedicated to maintaining protein homeostasis, primarily within the endoplasmic reticulum (ER). This pathway diligently responds to a variety of intracellular indicators of ER stress with the objective of reinstating balance by diminishing the accumulation of unfolded proteins, amplifying the ER's folding capacity, and eliminating slow-folding proteins. Prolonged ER stress and UPR irregularities have been linked to a range of neuropsychiatric disorders, including major depressive disorder, bipolar disorder, and schizophrenia. This review offers a comprehensive overview of the UPR pathway, delineating its activation mechanisms and its role in the pathophysiology of neuropsychiatric disorders. It highlights the intricate interplay within the UPR and its profound influence on brain function, synaptic perturbations, and neural developmental processes. Additionally, it explores evolving therapeutic strategies targeting the UPR within the context of these disorders, underscoring the necessity for precision and further research to effective treatments. The research findings presented in this work underscore the promising potential of UPR-focused therapeutic approaches to address the complex landscape of neuropsychiatric disorders, giving rise to optimism for improving outcomes for individuals facing these complex conditions.

  • Colorectal cancer (CRC), now the third most common cancer across the world, is known to aggregate in families. USP7 is a very important protein with an important role in regulating the p53 pathway, which is critical for genomic stability and tumor suppression. We here genotyped eight SNPs within the USP7 gene and conducted a case-control study in 312 CRC patients and 270 healthy subjects in the Chinese Han population. No significant associations were found for any single SNP and CRC risk. Our data eliminate USP7 as a potential candidate gene towards for CRC in the Han Chinese population.

  • Many disorders in neuropsychiatric field demonstrate variable motor disturbances as their clinical feature or in their courses of illness and also due to psychopharmacological treatment. Although association of such motor disturbances with the pathophysiological aspect of various neuropsychiatric illness are still lacking, some form of motor disturbance offer a window through which pathophysiologic mechanism of such illnesses can be viewed. Cognitive control of motor functions are briefly reviewed in this article and the importance and method of motor function assessment in major neuropsychiatric disorders are also discussed. Motor dysfunction of major neuropsychiatric illness such as schizophrenia and mood disorders may offer a chance of a deeper understanding on the pathophysiologic aspect of their clinical presentation.

  • Objectives : In the psychiatry, structured interview is very important tool to be used in epidemiological or psychopharmacological studies. However, investigators often find that the administration of comprehensive diagnostic interviews is time-consuming and expensive to be used in clinical or research settings. Considering these points, Sheehan and his colleagues developed MINI (Mini International Neuropsychiatric Interview) to meet the need for a brief, reliable, and valid structured diagnostic interview for psychiatric disorders. The MINI has been translated into many languages and used in many countries. Therefore, we translated the MINI into Korean and determined its validity in this study. Methods : Twohundred seventy patients and normal subjects participated in the validation of the MINI versus an expert's professional opinion. Schizophrenia and other psychotic disorders, mood disorders including major depressive disorder and bipolar disorder, anxiety disorders including panic and other phobic disorders, and alcohol dependence were included in this study. The validity was obtained by examination whether MINI based diagnoses were compatible with diagnoses by expert psychiatrists. Results : The range of Kappa values was 0.22 (somatoform disorder) to 0.93 (bipolar disorder - past). Overall agreement between MINI and expert's diagnoses were good. The Kappa values for anxiety disorders seemed to be higher than those for other disorders. Conclusion : The MINI Korean version has the good validity. It also has potential applications as a diagnostic tool for psychiatric disorders.

  • The primary purpose of this review is to present an overview of relationship between human spontaneous eyeblinking and internal cognitive processes. The second purpose is to address the neural substrates of human eyeblinking based on recent studies focusing on the central dopaminergic system and to explore the significance of spontaneous eyeblinks in neuropsychiatric disorders. We reviewed recent and previous studies on eyeblink patterns under various cognitive tasks. We also reviewed neural substrates of eyeblinking, particularly based on the central dopaminergic system. This paper suggests that spontaneous eyeblinks are highly correlated with various cognitive processes and the activity of central dopaminergic system. Various neuropsychiatric disorders are related to the alteration of the occurrence of eyeblinking. Spontaneous eyeblinking is the unique human behavior that occurs regularly without conscious effort. It is known that the rate of eyeblinking is modulated by internal cognitive processes and dopamine-related neuropsychiatric disorders. Further research is required to how the temporal dynamics of spontaneous eyeblinking is correlated with the disease activity and progression.

  • Objectives: Gan Mai Da Zao (GMDZ) decoction is widely used for the treatment of various diseases of the internal organ and of the central nervous system. The aim of this study is to investigate the effects of GMDZ decoction on neuropsychiatric disorders in an animal model. Methods: We searched seven databases for randomized animal studies published until April 2015: Pubmed, four Korean databases (DBpia, Oriental Medicine Advanced Searching Integrated System, Korean Studies Information Service System, and Research Information Sharing Service), and one Chinese database (China National Knowledge Infrastructure). The randomized animal studies were included if the effects of GMDZ decoction were tested on neuropsychiatric disorders. All articles were read in full and extracted predefined criteria by two independent reviewers. Results: From a total of 258 hits, six randomized controlled animal studies were included. Five studies used a Sprague Dawley rat model for acute psychological stress, post-traumatic stress disorders, and unpredictable mild stress depression whereas one study used a Kunming mouse model for prenatal depression. The results of the studies showed that GMDZ decoction improved the related outcomes. Conclusion: Regardless of the dose and concentration used, GMDZ decoction significantly improved neuropsychiatric disease-related outcomes in animal models. However, additional systematic and extensive studies should be conducted to establish a strong conclusion.

  • Objectives: To perform a systematic review of placenta pharmacopuncture for treating neuropsychiatric diseases, focusing on its efficacy and the safety so that evidence on its clinical use could be obtained, thus contributing to further studies. Methods: Through Korean, English, and Chinese databases (OASIS, Korean TK, KISS, RISS, ScienceON, Pubmed, Cochrane, EMBASE, CINAHL, AMED, CNKI, and Wanfang), combinations of keywords (placenta, pharmacopuncture, etc.) were used to select clinical studies published until January 2021 about placenta pharmacopuncture for neuropsychiatric diseases. Interventions included combined treatments. Study design included cases studies, series, and clinical trials. Cohort studies, literature reviews, in vitro and animal experiments were excluded. The primary outcomes involved measurements of symptoms, Visual Analogue Scale, or questionnaires. Data extracted from databases were imported to Endnote X7 to remove duplicates. The quality of the literature was assessed based on CAse REports Guidelines and Cochrane's Risk of Bias (ROB). Results: Twenty-one studies were selected, including ten case reports, three case series, two one-armed clinical trials, one non-randomized clinical trial, and five randomized clinical trials. There were six studies on sleep disorders, five studies on stroke sequela, two on mood disorders, two on enuresis, two on Guillain-Barré syndrome, two on multiple sclerosis, one on neurocognitive disorder, and one on vertigo. The most frequent combined treatment was acupuncture in both the experimental group (n=10) and the control group (n=3). Acupoints were ST36, SP6, BL23, CV4, GB20, GV20, N-HN54, and so on. All studies reported improvement of symptoms. The quality of case studies was relatively high. Assessment of ROBs resulted in low risks. Conclusions: Placenta pharmacopuncture is effective for neuropsychiatric diseases such as sleep disorders, mood disorders, enuresis, and neurocognitive disorders. Regarding insomnia, several studies have reported significant improvements with placenta pharmacopuncture. There was no adverse event associated with placenta pharmacopuncture.

  • Particular matter is steadily increasing due to environmental factors at domestic and abroad such as industry and economy. Recently, the exposure particular matters has been reported to increase the risk not only for morbidity and mortality, but also for diseases of the respiratory system, cardiovascular system and central nervous system/neuropsychiatric disorder. Although the causes of neuropsychiatric diseases are genetic and environmental factors, it is necessary to pay more attention to environmental factors in terms of prevention. We mainly describe environmental factors that affect neuropsychiatric disorders, mainly on particular matter, which is one of harmful environmental substances. In the current study, we reviewed evidence for the presence of particular matter or particular matter related harmful air pollutants-O3, SO2, NO2/NOx, traffic related air pollution, that may represent risk factors for the development of neuropsychiatric disorder.

  • Visual perception is a complex process engaging many different aspects of brain functioning. Like other cognitive functions, the extensive cortical distribution and complexity of visual perceptional activites make them hihgly vulnerable to brain injury. Dectection and characterization of perceptual disorders require a careful clinical assessment as well as the application of selected neuropsychological tests. In this article we reviewed neuropsychological assessment of visual perception and constructional abilities. And the principal visuospatial disorders are discussed, the associated neuropsychiatric disorders are presented.
