ObjectiveTo investigate effects of anisodamine on myocardial caspase-1 and interleukin-18 expression following overtraining-induced acute myocardial injury in rats.Methods Forty-eight male Wistar rats weighing 200-220 g were randomly divided into 3 groups:group control (group C,n =8) ; group exhausting swim (group ES,n =24) and group anisodamine (group AD,n =16).The animal model of overtraining-induced acute myocardial injury was developed by exhausting swim The animals were forced to swim until they were exhausted.The animals sank to the bottom and no righting reflex or escape response was elicited when they were taken out of water in groups ES and AD.In group AD anisodamine 10 mg/kg was given intraperitoneally 20 min before overtraining.Blood samples were taken from inferior vena cava immediately (T1) and at 6 and 24 h after overtraining (T2,T3 ) in group ES and at T2,T3 in group AD for determination of serum cardiac troponin 1 (cTnI) concentration (by ELISA).The animals were sacrificed after blood sampling and myocardial specimens were obtained for microscopic examination and determination of caspase-1 and interleukin-18 expression (by immuno-histochemistry).ResultsOvertraining significantly increased serum cTnI concentration and up-regulated myocardial caspase-1 and interleukin-18 expression in group ES as compared with group C.Anisodamine significantly attenuated overtraining-induced increase in serum cTnI concentration and myocardial caspase-1 and interleukin-18 expression in group AD as compared with group ES.ConclusionAnisodamine can reduce overtraining-induced acute myocardial injury by down-regulating caspase-1 and interleukin-18 expression.

Objective To model the newborn hypoxic-ischemic brain damage in rats. Methods 25 7-day-old healthy Wistar rats were divided into control group (n=12) and model group (n=13). 2 h after ligating and mutilating the unilateral common carotid arteries, the rats in the model group were put into an airtighted box with the volume fraction of 8% oxygen and 92% nitrogen for 2 h. 4 weeks after operation, all the rats were assessed behaviorally and pathologically. Results The footprint repeat space of rats were larger and more instable in the model group than in the control group (P<0.05). The time the rats crossing the balance beam was longer in the model group than in the control group (P<0.05). The escape latency of the water maze test was longer in the model group than in the control group (P<0.05). The right brain became smaller than the contralateral. HE staining showed that the cells around impaired periventricle were swelling, and cell number was less than the contralateral. The neurons decreased, some degenerated and necrosis neurocytes appeared in the impaired side. Conclusion The model of hypoxic-ischemic brain damage has been established.

BACKGROUND:Hepatic fibrosis in chronic liver disease can be reversed. Studies have shown that Periplaneta americana extract has anti-fibrosis effect, and has protective effect on the experimental hepatic fibrosis rats.
OBJECTIVE:To observe the effect of Periplaneta americana extract sticky sugar amino acid on hepatic fibrosis, and to primarily explore the mechanism of sticky sugar amino acid against hepatic fibrosis.
METHODS:Rat models of immune hepatic fibrosis were induced by pig serum and intragastricaly administered 0.5, 0.25, 0.10 g/kg sticky sugar amino acid. Four indexes of hepatic fibrosis were detected by radioimmunoassay. Immunohistochemical staining wasused to measure transforming growth factor beta 1, tissue inhibitor of metaloproteinase protein expression intensity and positive cel rate, to determine the correlation of different concentrations of sticky sugar amino acid, transformation growth factorbeta 1 and tissue inhibitor of metaloproteinase.
RESULTS AND CONCLUSION:(1) The Periplaneta americana extract sticky sugar amino acid reduced the levels of laminin, type III procolagen, type IV colagen and hyaluronidase (P< 0.01) and reduced the expression of transformation growth factor beta 1 and tissue inhibitor of metaloproteinase 1 in liver tissue (P< 0.01). (2) Sticky sugar amino acid concentration and transformation growth factor beta 1 and tissue inhibitor of metaloproteinase 1 protein expression showed a significant negative correlation (|r| > 0.9). (3) Results confirmed that the Periplaneta americana extract sticky sugar amino acid can change the reversal of hepatic fibrosis. Its mechanism of action is associated with expression of transforming growth factor beta 1 and tissue inhibitor of metaloproteinase 1 inhibited by sticky sugar amino acids.

Objective:To explore the correlation between nurses′ workplace adaptability, moral dilemma and resilience after suffering workplace violence in emergency department, in order to provide reference about improving the workplace adaptability and formulating intervention.Methods:A cross-section survey was conducted, we selected 248 nurses who had suffered workplace violence in the emergency department of five tertiary hospitals in Qingdao from January 2022 to January 2023 by convenient sampling method, and used self-designed general information questionnaire, moral dilemma scale, resilience evaluation scale for medical staff and nurses′ workplace adaptability scale to conduct a questionnaire survey on nurses who had suffered workplace violence, and found out the factors affecting their workplace adaptability.Results:The score of workplace adaptability of 248 nurses who had suffered workplace violence was (39.37 ± 12.77) points. Univariate analysis showed that education, length of emergency service, department or social part-time job, professional title, number of night shifts and sleep condition were the influencing factors of workplace fitness for emergency nurses ( t/ F values were -12.72 to 132.15, all P<0.05). The correlation analysis showed that the nurses′ workplace adaptability after workplace violence was negatively correlated with the scores and total scores of all dimensions of moral dilemma ( r values were -0.725 to -0.194, P<0.05), and positively correlated with the scores and total scores of all dimensions of resilience ( r values were 0.135 to 0.732, P<0.05). Multi-factor results showed that education background, department/social part-time job, working years, professional title, sleep status, moral dilemma and resilience were the influencing factors of nurses′ workplace adaptability after workplace violence ( t values were -9.25 to 15.25, P<0.05). Conclusions:Nurses with specialized education, emergency service for 1-3 years, no department/social part-time job, primary professional title, sleep disorder, higher degree of moral dilemma and low level of resilience have low occupational adaptability. Nursing managers should focus on such nurses and improve their occupational adaptability.
