Objective Several cell line studies have demonstrated thioridazine's anticancer, multidrug resistance-reversing and apoptosis-inducing properties in various tumors. We conducted this nationwide population-based study to investigate the association between thioridazine use and cancer risk among adult patients with schizophrenia. Methods Based on the Psychiatric Inpatient Medical Claim of the National Health Insurance Research Database of Taiwan, a total of 185,689 insured psychiatric patients during 2000 to 2005 were identified. After excluding patients with prior history of schizophrenia, only 42,273 newly diagnosed patients were included. Among them, 1,631 patients ever receiving thioridazine for more than 30 days within 6 months were selected and paired with 6,256 randomly selected non-thioridazine controls. These patients were traced till 2012/12/31 to see if they have any malignancy. Results The incidence rates of hypertension and cerebrovascular disease were higher among cases than among matched controls. The incidence of hyperlipidemia, coronary artery disease and chronic pulmonary disease did not differ between the two groups. By using Cox proportional hazard model for cancer incidence, the crude hazard ratio was significantly higher in age, hypertension, hyperlipidemia, cerebrovascular disease, coronary artery disease and chronic pulmornary disease. However, after adjusting for other covariates, only age and hypertension remained significant. Thioridazine use in adult patients with schizophrenia had no significant association with cancer. Conclusion Despite our finding that thioridazine use had no prevention in cancer in adult patients with schizophrenia. Based on the biological activity, thioridazine is a potential anticancer drug and further investigation in human with cancer is warranted.

뇌공학 분야에서 개발된 연상기억의 능력을 가지는 Hopfield 신경망을 구성하고, 신경정신질환 중에서 시냅스의 손실과 관련이 되어서 생기는 치매와 일부 정신분열증의 모델로 변형시키기 위하여 인공신경망의 시냅스를 Hoffman의 시냅스 제거법칙과 무작위 방법에 따라 제거하면서, 그에 따른 기억능력의 변화를 관찰하였다. 구성된 컴퓨터모델에서 기억능력의 저하는 시냅스의 감소가 상당히 진행되어야 나타났으며, Hoffman의 시냅스 제거법칙에 따랐을 때는 80% 제거를 기점으로 급격하게 나타났으며, 무작위 제거시는 더 적은 시냅스 제거율인 40% 제거 때부터 점진적으로 나타나는 양상을 보였다. 컴퓨터 모델의 기억력저하 양상이 실제환자에서 관찰되는 기억력저하 양상을 설명할 수 있기 위해서는 증상이 발현되는 시점의 시냅스 소실의 정도는 얼마나 되는지, 또한 시냅스의 소실은 어떤 규칙에 의해 일어나는지 아니면 무작위로 일어나는지에 관한 생물학적 실험의 필요성이 부각되었다. 이와 같이 컴퓨터모델을 이용하여 모의실험을 하고 연구의 방향을 잡은 후에 생물학적 실험으로 검증해 나간다면, 매우 효율적인 이론과 실험의 공조체제를 이루어 신경정신질환의 이해를 도울 수 있을 것이다.

Background: Depression is a common neuropsychiatric disease that shows astrocyte pathology. Ginsenoside Rf (G-Rf) is a saponin found in Panax ginseng which has been used to treat neuropsychiatric diseases. We aimed to investigate antidepressant properties of G-Rf when introduced into the L-alphaaminoadipic acid (L-AAA)-infused mice model which is representative of a major depressive disorder that features diminished astrocytes in the brain. Methods: L-AAA was infused into the prefrontal cortex (PFC) of mice to induce decrease of astrocytes. Mice were orally administered G-Rf (20 mg/kg) as well as vehicle only or imipramine (20 mg/kg) as controls. Depression-like behavior of mice was evaluated using forced swimming test (FST) and tail suspension test (TST). We observed recovery of astroglial impairment and increased proliferative cells in the PFC and its accompanied change in the hippocampus by Western blot and immunohistochemistry to assess the effect of G-Rf. Results: After injection of L-AAA into the PFC, mice showed increased immobility time in FST and TST and loss of astrocytes without significant neuronal change in the PFC. G-Rf-treated mice displayed significantly more decreased immobility time in FST and TST than did vehicle-treated mice, and their immobility time almost recovered to those of the sham mice and imipramine-treated mice. G-Rf upregulated glial fibrillary acidic protein (GFAP) expression and Ki-67 expression in the PFC reduced by L-AAA and also alleviated astroglial change in the hippocampus. Conclusion: G-Rf markedly reversed depression-like behavioral changes and exhibited protective effect against the astrocyte ablation in the PFC induced by L-AAA. These protective properties suggest that G-Rf might be a therapeutic agent for major depressive disorders.

Background : To estimate fall incidence rate and associated factors in inpatients from a general hospital. Method : The data were collected from 104 fall incident reports developed by the patient safety committee in a general hospital in Seoul from 01 January 2007 to 31 December 2008. Information included general characteristics of patients, factors related to fall, types, places, circumstances and outcomes of fall. Result : The incidence rate of fall, which was 4.4 per 1,000 total discharged patients and 0.5 per 1,000 patient-days, was much lower than that of several hospitals in the United States. The difference may reflect the different incidence reporting system of each hospital. Fall-prone patients were, in general, $$\geq_-$$65 years of age, had an alert mental status, were ambulatory with some assistance, and were dependent on and ambulatory device. High incidence of falls was associated with patients with circulatory disease. The majority of fall events usually occurred in bed or at the bedside in the patient's room, and occurred more often during the night than during the day or evening. Risk factors of fall were use of drugs (antihypertensive or neuropsychiatric drugs) and environmental factors (e.g., overly high bed height, surrounding objects, inadequate fitness shoes and slippery floor). Physical injury occurred in 43.3% of fall events, which typically required diagnosis of injury and treatment such as suturing. Risk factors for repeated falls were use of a neuropsychiatric drug (odds ratio=13.9) and gait disturbance (odds ratio=91.2). Risk factors for fall-related injury were alert mental status (odds ratio=3.3 times more likely to fall than those who were drowsy or in a stupor) and general weakness(odds ratio=3.3 times more likely to fall than those who were not generally weak). Conclusion : Medical and nursing staff should be aware of the fall risk factors of hospitalized patients and should intensively pursue preventative strategies. Development of fall prevention education based on these results is recommended.

Purpose: For mothers just delivered of a child, sanhupung(産後風) is a critical disease which can threaten their health. The symptoms of sanhupung were diverse and divided into pain symptoms, general symptoms, and neuropsychiatric symptoms. We tried to search for the relationship between sanhupung and somatization of postpartum depression. Methods: Analysis was carried out with materials concerning the postpartum depression and sanhupung. For the analysis, materials related with the issue of this study were searched at the Korea Education & Research Information Service, and Oriental medicine advanced searching. Results: 1. The range of period and symptoms of sanhupung has been broaden. The symptoms of sanhupung were divided into pain syndrome, general symptoms, and neuropsychiatric symptoms. 2. As the symptoms of postpartum depression might indicate not only physical symptoms but also mental disorder, more attention should be placed on wether the symptoms were involved in somatization of postpartum depression. Conclusion: The authors conclude that obstinate sanhupung that do not healed up and improve in symptoms have a relation to somatization of postpartum depression.

Systemic lupus erythematosus (SLE) is an episodic, multi-system, autoimmune disease characterized by widespread inflammation of blood vessels and connective tissues and by the presence of antinuclear antibodies (ANAs), especially antibodies to native (double-stranded) DNA (dsDNA). Its clinical manifestations are extremely variable, and its natural history is unpredictable. Untreated, SLE is often progressive and has a significant fatality rate. The most widely used criteria for the classification of SLE are those of the American College of Rheumatology (ACR), which were revised in 1982 and modified in 1997. The presence of four criteria have been diagnosed as a SLE. Rashes are common at onset and during active disease. The oral mucosa is the site of ulceration with SLE. Arthralgia and arthritis affect most children and these symptoms are short in duration and can be migratory. Lupus nephritis may be more frequent and of greater severity in children than in adults. The initial manifestation of nephritis is microscopic hematuria, followed by proteinuria. The most common neuropsychiatric symptoms are depression, psychosis(hallucination and paranoia) and headache. CNS disease is a major cause of morbidity and mortality. Pericarditis is the most common cardiac manifestation. Libman-Sacks endocarditis is less common in children. The most frequently described pleuropulmonary manifestations are pleural effusions, pleuritis, pneunonitis and pulmonary hemorrhage. During the active phase ESR, CRP, gamma globulin, ferritin and anti-dsDNA are elevated. Antibodies to dsDNA occur in children with active nephritis. Antibodies to the extractable nuclear antigens (Sm, Ro/SS-A, La/SS-B) are strongly associated with SLE. Specific treatment should be individualized and based on the severity of the disease. Sepsis has replaced renal failure as the most common cause of death.

Huntington's disease (HD) is a neurodegenerative disorder, of which pathogenesis is caused by a polyglutamine expansion in the amino-terminus of huntingtin gene that resulted in the aggregation of mutant HTT proteins. HD is characterized by progressive motor dysfunction, cognitive impairment and neuropsychiatric disturbances. Histone deacetylase 6 (HDAC6), a microtubule-associated deacetylase, has been shown to induce transport- and release-defect phenotypes in HD models, whilst treatment with HDAC6 inhibitors ameliorates the phenotypic effects of HD by increasing the levels of α-tubulin acetylation, as well as decreasing the accumulation of mutant huntingtin (mHTT) aggregates, suggesting HDAC6 inhibitor as a HD therapeutics. In this study, we employed in vitro neural stem cell (NSC) model and in vivo YAC128 transgenic (TG) mouse model of HD to test the effect of a novel HDAC6 selective inhibitor, CKD-504, developed by Chong Kun Dang (CKD Pharmaceutical Corp., Korea). We found that treatment of CKD-504 increased tubulin acetylation, microtubule stabilization, axonal transport, and the decrease of mutant huntingtin protein in vitro. From in vivo study, we observed CKD-504 improved the pathology of Huntington's disease: alleviated behavioral deficits, increased axonal transport and number of neurons, restored synaptic function in corticostriatal (CS) circuit, reduced mHTT accumulation, inflammation and tau hyperphosphorylation in YAC128 TG mouse model. These novel results highlight CKD-504 as a potential therapeutic strategy in HD.
