The drafting of Zhejiang Mental Health Regulation has started since the promulgation of the Mental Health Law of the People's Republic of China in the year of 2013. Based on the preliminary investigation and the practice of mental health work in Zhejiang Province,this paper introduces the contents and characteristics of the regulation from six aspects,which are the legislative purpose and scope of application, the responsibilities of the government and departments, the construction of mental health service system,management of mental health services and consulting institutions,prevention,treatment and rehabilitation of mental disorders, and measures necessary to implement the regulation.

OBJECTIVE: To explore the effects of three dentine desensitizers on the surface morphology of freshly exposed dentin and to evaluate their occlusion effects on dentinal tubules using scanning electron microscope (SEM). METHODS: A total of 16 isolated human premolar samples, which were prepared to expose dentine, were randomly divided into a control group (n=4), a Hybrid Coat group (n=4), a Prime & Bond NT group (n=4), and a anti-sensitivity toothpaste group (n=4). After treatment with dentine desensitizers, one half of the samples in each group were vertically cleaved. Finally, the surfaces and cross sections of the samples were observed by SEM. RESULTS: The exposed tubule was almost occluded in the Hybrid Coat group and the Prime & Bond NT group, while only the majority of tubules could be sealed in the anti-sensitivity toothpaste group. The cross-section images showed that sediments were visible in all groups except the control group. CONCLUSION Hybrid Coat and Prime & Bond NT are able to effectively seal tubules, while the effect of anti-sensitivity toothpaste is slightly poor.

Objective To analyze the features of cervical vertebra X-ray examination and transcranial Doppler (TCD) in children with cervical vertigo, and investigate the mechanism of the disease. Methods X-ray examination of cervical vertebra and TCD were performed on 80 children with cervical vertigo, and the features of the results were analyzed. Results The abnormal results of cervical X-ray examination mainly showed atlantoaxial joint or/and C2, C3 vertebral joint disorders, some of which combined with cervical instability, cervical curvaturestraightened and even reverse curvature, cervical scoliosis. The abnormal results of TCD showed the blood flow velocity in single or multiple branch of artery increased mainly, some of which decreased or became asymmetrial. Conclusion The cervical vertigo in children may result from various kinds of disorders of the atlas, axis or/and C2, C3 vertebrae.

OBJECTIVE: To analyze the usage of mental health assistance hotline during COVID-19 in Zhejiang province from January 25th to February 29th 2020, and summarize the characteristics of the demand for mental health services and the dynamic changes of public mental health status during COVID-19 pandemic. METHODS: Both quantitative and qualitative methods were used. The calls related to pandemic were divided into four categories: medical, psychological, information and the others. The secondary categories of psychological calls were determined by text analysis. The number of calls were calculated weekly and the number of various types of calls over time were analyzed. We used stratified random sampling method to extract 600 cases of all kinds of calls related to pandemic and conducted a semantic analysis, through marking new, similar combination to form a feature set, then summed up the call content characteristics of each stage. Two hundred callers were followed up to understand how they felt about the call process in four aspects: the waiting time, call duration, the degree of problem-solving and the way to end the call. RESULTS: In a total of 13 746 calls, 8978 were related to pandemic, among which 12.59%(1130/8978) were about medical issues, 26.50%(2379/8978) were about mental health, 27.18%(2440/8978) were about information regarding the pandemic and 33.74%(3029/8978) were about other pandemic related issues. Pandemic situation, relevant policy release, frequency of advertising campaigns were predictors of the number of calls per day during the pandemic (<0.05 or <0.01). The number of calls differed by gender and identities of callers (both <0.05). Finally 181 callers accepted telephone follow-up. Among them, 51.38%(93/181) of the callers thought that the waiting time was too long, 33.15%(60/181) of the callers thought that the call time was insufficient, 80.66%(146/181) of callers believed that the hotline could partially or completely resolve their concerns, and 39.23%(71/181) of the callers said the operator proposed to end the call. CONCLUSIONS s The changes of the number and content of the mental health assistance hotline calls reflected that the public mental health status experienced four stages during the pandemic: confusion, panic, boredom, and adjustment. The specialized mental health assistance hotlines should be further strengthened, and the efficiency should be improved. Mental health interventions should be tailored and adopted according to the characteristics of the public mental health status at different stages of the pandemic.
