Objective:To compare clinical characteristics,treatment patterns and physiological indicators in bipolar disorder(BD)patients with different age of onset.Methods:Totally 380 patients with DSM-5 BD were se-lected in this study.Psychiatrists diagnosed the patients using the Mini International Neuropsychiatric Interview.The clinical information questionnaire and the Global Assessment of Functioning scale were utilized to collected clinical characteristics,treatment status,and physiological indicators.The onset age of BD was divided into 21 and 35 years as cut-off points.Multivariate logistic regression and linear regression were used to analyze related factors.Results:Among the 380 patients with BD,199 cases were early-onset group(52.4％),121 cases were middle-onset group(31.8％),and 60 cases were late-onset group(15.8％).There were 26.6％of patients in the early-onset group in-itially diagnosed as depression,23.1％in the middle-onset group,and 11.7％in the late-onset group.Multivariate analysis revealed that compared to the early-onset group of BD,the middle-onset(OR=2.22)and late-onset(OR=4.99)groups had more risk to experience depressive episodes,and the late-onset group(OR=6.74)had 6.74 times of risk to suffer from bipolar Ⅱ disorder.Additionally,patients in the middle-onset(β=-1.52)and late-on-set(β=-4.29)groups had shorter durations of delayed treatment,and those in the middle-onset(β=-1.62)and late-onset(β=-3.14)groups had fewer hospitalizations.Uric acid levels were lower in both the middle-onset(β=-28.39)and late-onset(β=-31.47)groups,and total cholesterol level was lower in the middle-onset group(β=-0.23).Conclusion:Patients with BD in different age of onset show significant differences in clinical charac-teristics,treatment conditions and physiological indicators.

Objective:To estimate the costs of dementia from a societal perspective in Tongliao City and ex-plore the influencing factors of these costs.Methods:Dementia was diagnosed using the 10/66 Dementia Research Group assessment instruments.Data on healthcare utilization,caregiver's care time or costs,and the distress due to caregiving were collected.The cost-proportion conversion method was used to estimate the per capita cost of health services based on data from the National Statistical Yearbook.The human capital approach was used to estimate the unit value of informal care time,and the willingness-to-pay method was used to measure the intangible costs of car-egivers.The total societal costs of dementia were calculated based on the reference year 2023,and a two-part model was employed to analyze the factors influencing the societal costs.Results:A total of 390 dementia patients were di-agnosed,with an average societal cost per capita of 117 877 Yuan.The largest cost component was informal care provided by unpaid family members,accounting for 73.1％of the total societal cost.The societal costs for female patients were 61 395 Yuan higher than those for male patients.Patients with comorbid stroke had a higher societal cost of 63 008 Yuan compared to patients without stroke,and each additional chronic disease added 5 868 Yuan to societal costs.Additionally,each non-memory dimension impairment in the Clinical Dementia Rating Scale in-creased the societal costs by 53 997 Yuan.Conclusion:Dementia poses a significant socio-economic burden,with informal care being the major component of this burden.

2019 novel coronavirus(2019-nCoV) outbreak is one of the public health emergency of international concern.Since the 2019-nCoV outbreak, China has been adopting strict prevention and control measures, and has achieved remarkable results in the initial stage of prevention and control.However, some imported cases and sporadic regional cases have been found, and even short-term regional epidemics have occurred, indicating that the preventing and control against the epidemic remains grim.With the change of the incidence proportion and the number of cases in children under 18 years old, some new special symptoms and complications have appeared in children patients.In addition, with the occurrence of virus mutation, it has not only attracted attention from all parties, but also proposed a new topic for the prevention and treatment of 2019-nCoV infection in children of China.Based on the second edition, the present consensus further summarizes the clinical characteristics and experience of children′s cases, and puts forward recommendations on the diagnostic criteria, laboratory examination, treatment, prevention and control of children′s cases for providing reference for further guidance of treatment of 2019-nCoV infection in children.

Depression is a long-term and recurrent mood disorder. Transcranial magnetic stimulation (TMS), as a noninvasive antidepressant therapy, has been fully confirmed regarding to its efficacy and safety. However, major limitations remain when utilizing TMS due to the difficulties of accurately locating the treatment target and prediction of the efficacy. To date, there are accumulating studies applying the MRI technic to target the treatment location and predict efficacy when using TMS in the treatment of depression. The aim of the paper is to summarize the progress of the application of TMS with MRI.
