Objective To reveal the relation between Nesiritide and vascular remodeling,the relation between Nesiritide and the levels of aldosterone.Methods 20 male New Zealand rabbits were randomly divided into two groups.All rabbit models were constructed with BC.After injury,the control group were fed with standard forage,the Nesiritide group received standard forage plus subcutaneous Nesiritide[0.1 mg/dissected free from arteria iliaca externa,processed for histological and morphological study by TD 2000 analysis system of pathology image.Data of vascular remodeling and the levels of plasma aldosterone were determined.Results There had significant difference between AUIEM and AUEEM(P ＜ 0.05),markedly significant difference was also found in residual cavity areas and ratios of stenosis(P ＜0.01).There had no significant difference between areas of media(P ＞ 0.05).Aldosterone reduced from the 28th day.Conclusions Nesiritide could benefit vascular remodeling after angioplasty,which might be through reducing aldosterone.

Background The mental health status of prison officers is crucial to the efficiency, security, and stability of a prison, and it is essential to pay attention to the factors that influence their mental health. Objective To understand the mental health status of prison officers, and analyze how nature exposure affects their mental health problems and a potential mediating role of mental fatigue. Methods A cross-sectional survey was carried out from May to June 2022 among 1392 prison officers from eight prisons in a province, and a total of 1284 valid questionnaires were recovered. The Nature Exposure Scale, Mental Fatigue Scale, and Depression-Anxiety-Stress Scale were used to assess nature exposure, mental fatigue, and mental health indicators among prison officers, and to explore the effect of nature exposure on mental health problems and a potential mediating role of mental fatigue. Results The recruited prison officers showed high levels of depression, anxiety, and stress. The prevalence rates of depression, anxiety, and stress were 59.11% (759/1284), 60.67% (779/1284),and 43.93% (564/1284), respectively. The results of correlation analysis revealed that nature exposure was negatively related with mental fatigue and mental health indicators (depression, anxiety, and stress) (r_s=−0.242, −0.308, −0.235, −0.254, P<0.01), while mental fatigue was positively correlated with mental health indicators (depression, anxiety, and stress) (r_s=0.546, 0.533, 0.536, P<0.01). The PROCESS macro results showed that the level of nature exposure among prison officers negatively associated with depression, anxiety, and stress (β=−0.180, −0.104, −0.123), and mental fatigue played a mediating role, with indirect effects of −0.200, −0.192, and −0.199, respectively. Conclusion The levels of depression, anxiety, and stress of prison officers are higher than those of other occupations. Nature exposure negatively associates with depression, anxiety, and stress, that is, it may directly alleviate the mental health problems of prison officers; and it may also alleviate mental health problems by relieving mental fatigue.

OBJECTIVE： To explore the mechanism of Lysimachia christinae in the treatment of cholecyst related diseases by network pharmacology. METHODS： The active ingredients of L. christinae were screened through TCMSP database with “Lipinski rule” and “Oral bioavailability ＞30％” rules， and their related targets were predicated correspondingly， then compound-target network were constructed by Cytoscape 3.2.1 software. Disease related targets were predicted by searching TTD database， OMIM database， PharmGKB database， DrugBank database and GAD database with “cholelithiasis” “gallstones” “cholecystitis” and “cholangitis” as keywords. Then， the network of disease-target was constructed and merged with active ingredient target to obtain therapeutic target. After pathway enrichment analysis of therapeutic target were performed by utilizing the DAVID database， molecular docking between target and active ingredient was also conducted in order to screen the main active ingredients of L. christinae. RESULTS： Twenty-seven active ingredients with good oral absorption and drug-like properties were screened from L. christinae. Thirty-three targets were attained after constructing and merging the network. Seven pathways， mainly related to cancer pathway and ABC transporter pathway were achieved. Top 4 active ingredients of L. christinae in the list of docking score were kaempferin， acacia， hesperetin and isorhamnetin， which acted on ABCC3， ABCB1， ABCC2， ABCB4 target. CONCLUSIONS： L. christinae treat cholecyst related diseases through ABC transporter pathway.
