Objective To compare imaging quality and radiation dose on full-field digital mammography (FFDM) system and dual-sided reading CR mammography (DSCRM) system.Methods The TRM of ALVIM statistics phantom was exposed by FFDM system and (DSCRM) with the same radiation dose.The exposure parameters and the entrance surface dose (ESD) were recorded.Then,the phantom was exposed by DSCRM system with different mAs and same kV,and the ESD was recorded.The images obtained above were read by three radiologists on the monitor of diagnosis work station with the same window width and window level.The evaluation of the images were given using a five-level confidence scale.ROC curves were drawn and probability Pdet were calculated.Results The ROC analysis of microcalcifications and masses showed A(z) values of 0.730-0.925 and 0.670-0.945 for FFDM,and 0.632-0.815 and 0.575-0.785 for DSCRM when the radiation dose is 1.36 mGy.The radiation dose with DR system could be reduced compared with dual-sided reading CR system at the same probabilities Pdet,the ESD reduced from 1.63 mGy to 1.36 mGy by 19.8％,the AGD reduced from 0.65 mGy to 0.56 mGy by 16.0％.Conclusions The observable details with FFDM system were proved to be superior to DSCRM system at the same radiation dose.With the similar image quality,the radiation dose of FFDM system was less than the DSCRM system.

Objective To investigate the clinical efficacy of Kirschner wire,reconstruction plate and locking compression plate internal fixation in the treatment of Robinson type 2A and 2B midshaft clavicle fracture.Methods One hundred and fifty patients with midshaft clavicle fracture in the hospital from August 2006 to August 2015 were selected and divided into the group A,B and C.The group A adopted Kirschner wire,group B adopted the reconstruction plate and group C adopted the locking compression plate internal fixation.Then the incision length,operative time,intraoperative blood loss,fracture healing time,postoperative Constant-Murley scores and DASH scores and postoperative complications incidence rate were compared among the three groups.Results The incision length,operative time and intraoperative blood loss in the group A and C were significantly better than those in the group B(P＜0.05).The fracture healing time,postoperative activity,muscle strength and daily life score,postoperative complications incidence rate,postoperative DASH score in the group C were significantly better than those in the group A and B(P＜0.05).Conclusion The locking compression plate in the treatment of Robinson type 2A and 2B midshaft clavicle fracture can effectively reduce the surgical trauma,shortens the fracture healing time and decreases the postoperative complications.

Objective This research aims to investigate the impact of Orff music therapy on long-term schizophrenic patients in hospitals.Methods The study was a randomized,single-blind controlled trial conducted from April,2023 to September,2023.From April to September 2023,sixty-eight individuals diagnosed with persistent schizophrenia were enrolled and evenly distributed into a pair of cohorts:a treatment group of thirty-four people receiving the intervention,and an equal number forming the control group for comparative purposes.Individuals enrolled in the experimental arm of the study were administered Orff-music therapy alongside routine rehabilitation treatment across a span of two months.For a period of 8 weeks,the control group was given only standard rehabilitation treatment,whereas the research group underwent Orff-music therapy in addition to the standard rehabilitation treatment.Results Before treatment,there were no significant differences in the positive and negative symptoms scale(PANSS),the inpatient psychosis rehabilitation observe scale(IPROS)and the personal and social performance scale(psp)between two groups.After intervention,the PANSS showed that the changes were better in the study group than in the control group in 3 indicators:negative symptoms(-3.20±4.13 vs.-0.17±2.43,P<0.001),general symptoms(-2.79±3.83 vs.-0.17±2.99,P=0.003)and the total scores(-5.88±6.36 vs.0.00±4.08,P<0.001),but not in positive symptoms(P>0.05).The IPROS showed that the performances of patients in the study group were better than the control group in terms of participation in work therapy(-0.82±2.08 vs.0.23±2.10,P=0.041),socialization(-0.59±1.94 vs.0.53±1.69,P=0.014)and ability to live(-0.94±2.50 vs.0.15±1.48,P=0.033),the changes in scores before and after the intervention were significantly different when compared to the control group.The PSP showed that the changes in scores before and after the treatment of the study group was better than the control group in terms of social activity[0(-1,0)vs.0(0,0),P=0.011],and self-care[0(-1,0)vs.0(-0.25,0),P=0.012]were better than the control group.Conclusion For long-term hospitalized patients with chronic schizophrenia.Orff-music therapy can be a powerful tool for alleviating mental issues,fostering social functioning,and enhancing rehabilitation results.

Objective:To investigate the predictive value for major adverse cardiovascular events (MACE) occurring within 1 year in patients with old myocardial infarction(OMI) using characteristics of myocardial scar derive from dual-energy CT (DECT) post-processing technique.Methods:OMI patients who received coronary CT angiography following dual-energy CT with late iodine enhancement (LIE-DECT) in the Second Affiliated Hospital of Nantong University from November 2019 to October 2022 were continuously included, and the images of all enrolled patients were reconstructed using 40 keV monoenergetic plus (Mono+) map, LIE (representing myocardial scar) was quantified on left ventricular short-axis images, including the LIE segments, the LIE score, and the LIE degree. All enrolled patients were followed up for MACE, defined as hospitalization for heart failure, malignant arrhythmia, and cardiac death. Regression analysis was used to investigate the relationship between the quantified value of myocardial scar and the occurrence of MACE, and receiver operating characteristic curve (ROC) was used to evaluate the efficacy of quantified value of myocardial scar in predicting MACE. The area under the curve (AUC) was compared using the DeLong test.Results:Finally, 231 patients with OMI were included, and MACE occurred in 37 cases (16.0%) within 1 year after LIE-DECT examination. The LIE segments 5 (4, 7), the LIE score 27 (13, 49) and the LIE degree 9.4%(7.5%, 15.5%) in the MACE group were higher than those in the non-MACE group 3 (2, 5), 9 (6, 15) and 6.7%(6.3%, 7.9%) (all P<0.001). Multivariable logistic regression analysis showed that after adjusting for confounders, the LIE segments ( OR=2.118, P<0.001), the LIE score ( OR=3.168, P<0.001), and the LIE degree ( OR=3.092, P<0.001) remained risk factors for the development of MACE. On ROC analysis, AUC of LIE segments, LIE score and LIE degree were 0.715, 0.822 and 0.806 (all P<0.001), with sensitivities of 81.1%, 86.5%, and 91.9%, and specificities of 53.6%, 69.6%, and 60.8%, respectively. DeLong′s test showed that the predictive efficacy of LIE score and LIE degree was higher than that of LIE segments ( Z=2.63, P=0.008; Z=1.96, P=0.049), and there were no significant differences in the predictive efficacy of LIE score and LIE degree ( Z=0.60, P=0.551). Conclusion:The LIE segments, the LIE score and the LIE degree detected by LIE-DECT 40 keV Mono+maps are risk factors for the occurrence of MACE in patients with OMI and have good efficacy in predicting the occurrence of MACE, which can be used as important indicators for assessing the clinical prognosis of OMI.

The " liver disease affecting to the spleen" theory first appeared in Nanjing and was further elaborated in Jingui Yaolue. This theory encapsulates the traditional Chinese medicine principles of the " unity of the five viscera" and the " preventive treatment of disease" . The theory emphasizes that the spleen is the pivotal point where depression may progress from a functional disorder to an organic disease. The liver governs the emotions and qi flow, whereas the spleen is responsible for qi, blood, and body. In the early stages of the disease, emotional disorders and qi flow disorders primarily affect the liver, manifesting as depression or low mood. As the condition progresses, the liver (Wood) overacts on the spleen (Earth), disrupting liver and spleen functions and causing qi and blood disharmony. This stage is marked by fatigue and psychomotor retardation. Prolonged illness depletes qi and blood, eventually involving all five viscera, disrupting the harmony of the five spirits, and affecting both body and spirit. At this advanced phase, intense emotional distress or agitation often arises, accompanied by a heightened risk of suicide. The disease progression follows a dynamic " qi-blood-spirit" pattern, in which depression begins in the liver, characterized by qi stagnation, then affects the spleen, involving blood disharmony. In later stages, the disease eventually affects all viscera, with profound effects on both physical and mental health. Treatment strategies should align with the disease stage. Early intervention should focus on regulating the flow of qi, treating the liver, and strengthening the spleen. In the middle stages, qi and blood should be harmonized while promoting the harmonized functions of the liver and spleen. In the later stages, treatment should harmonize the five viscera to restore balance between body and spirit. Guided by this theory, integrating modern medical understanding of the progression of depression from emotional to somatic symptoms and adopting a stage-based approach to treatment in clinical practice can yield effective therapeutic outcomes for managing depression and related disorders.
