Purpose To observe the CT imaging features of dermatomyosistis patients with anti-melanoma differentiation related genes 5(MDA-5),and to analyze the relationship between CT imaging indicators and short-term prognosis of patients.Materials and Methods Sixty-seven MDA-5-positive dermatomyosistis patients admitted to China-Japan Friendship Hospital from January 2017 to December 2018 were retrospectively included.Prognosis of included patients in one year were followed-up.Analysis of the relationship between chest CT imaging and short-term poor prognosis.Results Among 67 patients,nine patients died in one year.There was a statistically significant difference between the two groups(the death group and the survivor group)in the interstitial lung disease(ILD)imaging types(χ2=0.198,P=0.025)and pulmonary/aortic diameter ratios(U=103.0,P=0.004).CT imaging of dermatomyosistis-ILD with anti-MDA5 antibody positive patients showed organizing pneumonia.Mortality of diffuse alveolar damage type was significantly higher than that of other types.Logistic regression analysis showed that pulmonary/aortic diameter ratio(OR:4.208,P=0.002)was a strong independent risk factor for the death of patients with anti-MDA5 antibody.Conclusion Most patients with anti-MDA5 antibody positive dermatomyositis show ILD,with the main feature of organic pneumonia.Patients with poor prognosis within 1 year have different types of ILD,while the pulmonary/aortic diameter ratio is a strong independent risk factor for the death of dermatomyosistis-ILD with anti-MDA5 antibody positive patients.

Objective To investigate the therapeutic effect and mechanism of NLRP3 inflammasome inhibitor-dapansutrile(OLT1177)-against acute radiation lung injury.Methods Mice were divided into the control group,OLT1177 injection group,irradiation group,and irradiation+OLT1177 injection group.A single dose of 22 Gy whole-lung 60Co radiation was used to establish a model of acute radiation lung injury.After 6 h of radiation,OLT1177(100mg/kg,once daily)was administered intraperitoneally.After 14 consecutive days of administration,lung tissues were collected and weighed while the lung coefficient was calculated.Hematoxylin-eosin(HE)staining and F4/80 immuno-histochemical staining were used to observe the pathological changes and inflammatory cell infiltration in lung tissues.Real-time quantitative PCR(qPCR)was used to detect the transcription levels of NLRP3,IL-1β,and other mRNAs in lung tissues.Serum cytokines such as TNF-α and IL-6 were measured by cytometric bead array(CBA).The activation of Caspase-1 and IL-18 was detected by Western blotting.Results Radiation caused acute inflammation in the lung tissues of mice,manifested as edema in the lung tissues and destruction of the alveolar structure,increased macrophage infiltration,and elevated expressions of inflammatory genes NLRP3,IL-1β,TNF-α,and IL-6 in the lung tissues and higher serum levels of TNF-α,IL-6.Treatment with OLT1177 significantly improved the above symptoms induced by radiation.OLT1177 inhibited the activation of NLRP3 inflammasome downstream Caspase-1 and IL-18 induced by radiation.Conclusion OLT1177 can significantly alleviate acute radiation lung injury in mice,which may be due to its inhibition of NLRP3 inflammasome activation induced by radiation.

Objective To investigate the role and mechanism of suramin(Sur)in acetaminophen(APAP)-induced acute liver injury in mice.Methods 8-10 weeks old C57BL/6J mice were randomly divided into the APAP group and APAP+Sur group(20 mg/kg suramin was injected 1 h before).After 18 hrs of fasting,400 mg/kg APAP was injected intraperitoneally to establish a mouse model of acute liver failure and the survival rate was recorded.An acute liver injury model of mice was established via intraperitoneal injection of 300 mg/kg APAP(other conditions remained unchanged).A control group was also established,with liver tissues and serum collected at 0,2,and 12 hours post-APAP treatment.ELISA and CBA techniques were adopted to detect the release of alanine aminotransferase(ALT)and aspartate aminotransferase(AST)in serum and the secretion of inflammatory factors.H&E staining and immunohistochemistry were used to detect liver tissue necrosis and inflammatory cell infiltration.DCFA-DH and ELISA techniques were used to detect the levels of reactive oxygen species(ROS),malondialdehyde(MDA)and glutathione(GSH)in liver tissues.Western blotting was employed to assess the activation of the JNK signaling pathway in liver tissues.Results Suramin treatment improved the survival rate of APAP-induced mice,reduced the release of transaminases and inflammatory factors in serum,and alleviated APAP-induced liver cell necrosis and inflammatory cell infiltration in the liver.Suramin treatment delayed APAP-induced GSH depletion in the liver,reduced MDA and ROS levels,and inhibited JNK pathway activation.Conclusion This study has confirmed the protective effect of suramin against acetaminophen-induced acute liver injury in mice.The mechanism is potentially related to oxidative stress and inflammation.

Bowel sounds can reflect the movement and health status of the gastrointestinal tract.However,the traditional manual auscultation method has subjective deviation and is time-consuming and labor-intensive.In order to better assist doctors in diagnosing bowel sounds and improve the reliability and efficiency of bowel sound detection,this study proposed a deep neural network model that combines a residual neural network(ResNet),a bidirectional long short-term memory network(BiLSTM),and an attention mechanism.Firstly,a large number of labeled clinical data was collected using the self-developed multi-channel bowel sound acquisition system,and the multi-scale wavelet decomposition and reconstruction method was used to preprocess the bowel sounds.Then,log Mel spectrogram features were extracted and sent to the network for training.Finally,the performance and effectiveness of the model were evaluated and verified by 10-fold cross-validation and an ablation experiment.The experimental results showed that the precision,recall,and F1 score of the model reached 83%,76%,and 79%,respectively,and it could effectively detect bowel sound segments and locate their start and end times,performing better than previous algorithms.This algorithm can not only provide auxiliary information for doctors in clinical practice but also offer technical support for further analysis and research of bowel sounds.

Objective:To explore whether there is a solution to the trilemma of health policy,and to reveal whether the health policy and policy portfolio can simultaneously improve the"health","wealth"and"equity"of residents.Methods:The study constructs a dynamic stochastic general equilibrium model and indicator estimation procedure that includes human health capital,and used Bayesian model comparison method to determine reasonable model settings.Using numerical simulation methods,by adjusting the corresponding parameters,it also simulates the policy effect of implementing comprehensive medical supervision policy and medical quality management policy separately,as well as the policy effects of combining these two policies.Results:Simply implementing comprehensive medical supervision policy may lead to the deviation of health outcomes from health affordability and financing equity,and simply implementing medical quality management policy may lead to the deviation of health affordability from health outcomes and financing fairness,and the combination of these two policies can effectively solve the trilemma of health policy.Conclusion:The problem of health policy trilemma is not unsolvable,and the mutual deviation of"health","wealth"and"equity"can be reconciled through reasonable policy combination design.
