Objective To evaluate the effect of crisis intervention on prevention of patients with mental disorder who had suicide ideas or attempt to commit resuicide.Methods 280 patients with mental disorder,holding suicidal ideas or attempting to suicide were randomly divided into the intervention group and control group with 140 cases in each group.The diagnosis of all patients was accorded with the CCMD-3 criteria.The cases of the control group only accepted routine treatments and cares in the hospital,and drug maintenance therapy after discharge.The cases of the intervention group accepted a comprehensive treatment of crisis intervention except the routine treatments.All cases were evaluated when they were admitted and 6 and 12 months after discharged.Results After discharged 6 months and 12 months,the social supports and treatments compliance of the intervention group were better than that of the control group(P<0.01),while suicidal ideas and the numbers of suicides were less than the control group significantly.Conclusion The crisis intervention can improve patients' social supporting and treatment compliance,eliminate their suicide ideas,and prevent the patients committing resuicide significantly.

Background Senescence marker protein 30 (SMP30) is a new calcium regulatory protein,which plays anti-oxidation,stable calcium and anti-apoptosis roles in vivo.Researches determined that the expression of SMP30 in human cells gradually decreased as ageing.However,the study on the relationship between SMP30 and age-related cataract is rarely.Objective The aim of this study was to investigate the expression of SMP30 in lens epithelial cells (LECs) of different ages of cataract patients.Methods This study was approved by Ethic Commission of the First Affiliated Hospital of Guangxi Medical University.A non-randomized controlled trail was designed.The samples of the anterior capsular membrane of lens were collected during the cataract surgery from the children group (1-18 years),youth group (19-45 years),mid adult group (46-60 years) and elder group (>60 years) and 12 pieces of capsular membrane for each group.In addition,12 pieces of lens capsular membrane from normal donors aged 19-45 years were obtained as normal control group.The expression of SMP30 in the samples was detected by indirect immunofluorescence method.The average fluorescent values were calculated as absorbance (A) / area.Results SMP30 was expressed in LECs of different groups with the green fluorescence primarily in the cytoplasm.The mean fluorescence intensity was 0.185±0.020,0.181±0.034,0.207±0.018 and 0.126±0.027 in the children group,youth group,mid adult group and elder group,respectively,which were significantly enhanced than 0.087±0.007 of the normal control group(q=3.96,3.82,4.01,3.55,all at P<0.01).No significant differences in the expression of SMP30 among the children group,youth group and mid adult group (all at P>0.05).However,the expression of SMP30 in LECs in the elder group was significantly lower than that in the children group,youth group and mid adult group (q =3.42,3.21,3.80,all at P< 0.05).Conclusions Expression of SMP30 in LECs dramatically increases in cataract patients,suggesting that SMP30 may be a protective factor for LECs.But SMP30 contents are lower in age-related cataract patients,which may be one of causes of senior cataract.

4.Intrinsic and extrinsic mechanisms regulating neuronal dendrite morphogenesis.
Journal of Zhejiang University. Medical sciences 2020;49(1):90-99
Neurons are the structural and functional unit of the nervous system. Precisely regulated dendrite morphogenesis is the basis of neural circuit assembly. Numerous studies have been conducted to explore the regulatory mechanisms of dendritic morphogenesis. According to their action regions, we divide them into two categories: the intrinsic and extrinsic regulators of neuronal dendritic morphogenesis. Intrinsic factors are cell type-specific transcription factors, actin polymerization or depolymerization regulators and regulators of the secretion or endocytic pathways. These intrinsic factors are produced by neuron itself and play an important role in regulating the development of dendrites. The extrinsic regulators are either secreted proteins or transmembrane domain containing cell adhesion molecules. They often form receptor-ligand pairs to mediate attractive or repulsive dendritic guidance. In this review, we summarize recent findings on the intrinsic and external molecular mechanisms of dendrite morphogenesis from multiple model organisms, including , and mice. These studies will provide a better understanding on how defective dendrite development and maintenance are associated with neurological diseases.
