ABSTRACT
With the fluctuating condition of the COVID-19 epidemic， the current findings remain unclear about the preventive measures and coping strategies for patients with severe mental disorders at the nodes of the transmission chain. Past experience in prevention and control has shown that establishing an effective system for emerging infectious disease prevention and control and establishing transitional wards in specialist mental healthcare institutions play a significant role in reducing the risk of epidemic transmission. However， there is no formulated strategy for the management of patients with severe mental disorders and COVID-19 infection who have recurrent or worsened mental symptoms during the diagnosis and treatment of COVID-19 and are unable to cooperate with the treatment in Fangcang shelter hospitals or infectious wards. Based on the field research in the front line of the epidemic prevention， this paper discusses the management strategies of patients with severe mental disorders and COVID-19 infection in the context of the practical difficulties in managing patients with severe mental disorders and COVID-19 infection， emergency management strategies， protective conditions for front-line psychiatric medical staff and the legal basis for the management of patients with severe mental disorders and COVID-19 infection in emergency situations.
ABSTRACT
To address the issue of weight gain and abnormal lipid metabolism caused by clozapine and olanzapine administration in patients with schizophrenia， a qualitative and systematic review was carried out， thus providing references for clinical treatment and future research. This review embraces the aspects of pharmacotherapy， traditional Chinese medicine treatment and so on.
ABSTRACT
Objective To observe the protective effect and mechanism of taraxasterol on cardiomyocytes in oxidative injury model caused by ischemia-reperfusion (I/R).Methods Mouse cardiomyocytes (CSC cells) were used as the study objects and divided into the normal control group,I/R group,taraxasterol treating I/R group (5,10,30 μmol/L) and positive control group.The cell viability was measured by MTT.The expressions of Caspase-3 and Bcl-2 were detected by RT-PCR.The expressions of superoxide dismutase (SOD) and malondialdehyde (MAD) were detected by biochemical methods.The expression of ERK1/2 was detected by western blot.Results MTT assay showed that 30 μmol/L taraxasterol increased the cell viability of CSC cells injured by I/R (P＜0.05).The RT-PCR results showed that the expression of Caspase-3 mRNA was decreased with 10,30 μmol/L taraxasterol treatment,the difference was statistically significant when compared with I/R group (P＜0.05).The expression of Bcl-2 mRNA was increased with 30 μmol/L taraxasterol treatment,the difference was statistically significant when compared with the I/R group (P＜0.05).The biochemical method detection showed that 30 μmol/L taraxasterol induced SOD expression was increased and MAD expression was decreased,the difference was statistically significant when compared with the I/R group (P＜0.05).Western blot detection showed that 30 μmol/L taraxasterol treatment increased the ratio of p-ERK1/2 to t-ERK1/2 in injured CSC cells (P＜0.05).Conclusion Taraxasterol might inhibit ischemia-reperfusion caused cardiomyocyte oxidative injury by up-regulation of ERK1/2 expression.
ABSTRACT
Objective To explore the effect of ParidissaponinⅠ (PSⅠ) on the proliferation of coronary artery endothelial cells (CAECs).Methods CAECs were cultured with PSⅠ.CAEC growth rate was calculated by using blood cell counting plate.Cell viability was measured by MTT.The expressions of cadherin and caspase3 mRNA were detected by RT-PCR.Results PSⅠ slowed down growth rate of CAECs,reduced cell viability of CAECs,decreased the expression of cadherin mRNA and increased the expression of caspase3 mRNA in CAECs.Conclusion PSⅠ inhibits the proliferation of CAECs and induces CAECs apoptosis.
