Studies have suggested that the nucleus accumbens (NAc) is implicated in the pathophysiology of major depression; however, the regulatory strategy that targets the NAc to achieve an exclusive and outstanding anti-depression benefit has not been elucidated. Here, we identified a specific reduction of cyclic adenosine monophosphate (cAMP) in the subset of dopamine D1 receptor medium spiny neurons (D1-MSNs) in the NAc that promoted stress susceptibility, while the stimulation of cAMP production in NAc D1-MSNs efficiently rescued depression-like behaviors. Ketamine treatment enhanced cAMP both in D1-MSNs and dopamine D2 receptor medium spiny neurons (D2-MSNs) of depressed mice, however, the rapid antidepressant effect of ketamine solely depended on elevating cAMP in NAc D1-MSNs. We discovered that a higher dose of crocin markedly increased cAMP in the NAc and consistently relieved depression 24 h after oral administration, but not a lower dose. The fast onset property of crocin was verified through multicenter studies. Moreover, crocin specifically targeted at D1-MSN cAMP signaling in the NAc to relieve depression and had no effect on D2-MSN. These findings characterize a new strategy to achieve an exclusive and outstanding anti-depression benefit by elevating cAMP in D1-MSNs in the NAc, and provide a potential rapid antidepressant drug candidate, crocin.

Primary hyperparathyroidism is a disease with a large potential population. Some cases of primary hyperparathyroidism are non-primary, preventable and curable at early stage, requiring long-term follow-up after surgery. Therefore, all-round and full-cycle management are necessary for primary hyperparathyroidism, which involves an enhancing focus on etiological prevention, early detection, prompt diagnosis, timely intervention, multi-disciplinary standardized diagnosis and treatment, and postoperative scientific management. Meanwhile, implementing a "12+5+1" multidisciplinary joint diagnosis and treatment model, along with a two-way referral model, to achieve the transition from a disease-oriented diagnostic and treatment model to a patient-oriented, all-round and full-cycle interdisciplinary management model. This management can reduce the incidence and recurrence rate of primary hyperparathyroidism, and related osteoporosis or osteopenia, fractures, nephrolithiasis, metastatic vascular calcification, and systemic abnormal migratory calcium deposits, improve the overall quality of life and prognosis of patients.

Objective To evaluate the application value of the three-point localization method in improving the quality and efficiency of four-chamber view acquisition in cardiac magnetic resonance(CMR)imaging.Methods A total of 215 patients who underwent four-chamber view in CMR imaging from January 2022 to October 2023 were retrospectively enrolled and divided into two groups.The control group(n=109)received traditional localization method while the study group(n=106)received three-point localization method.The image quality of mitral valve,tricuspid valve and cruciform structure in four-chamber view images were assessed by two radiologists using a Likert 4-piont scale.The time-consumption from scout imaging to the finish of four-chamber view imaging was recorded.Constituent data and numeral data were compared by Chi-square test and two-sample t test,respectively.Kappa test was used to analyze the inter-observer consistency.Results There were no significant inter-group differences in gender,age,disease profile,or the radiographers'experience.The mean quality scores of the mitral valve,tricuspid valve and cruciform structure in the control group and the study group were 3.44±0.64 and 3.63±0.49(P=0.023),3.43±0.67 and 3.53±0.60(P=0.202),3.71±0.49 and 3.83±0.35(P=0.047),respectively.The image quality score was higher in the study group than in the control group,with the differences in mitral valve and cruciform structure reaching statistical significance.The time-consumption for obtaining four-chamber view for the control group and the study group was 11.67±3.49 minutes and 7.212±1.83 minutes,respectively,with statistically significant differences(P＜0.001).Conclusion Compared with the traditional localization method,the three-point localization method provides better image quality in four-chamber view imaging with shortened imaging time.

Objective To investigate the value of abdominal aortic combined with routine one-stop triple rule-out computed tomography angiography(TRO-CTA)in the examination of patients with acute chest pain.Methods A total of 1 482 patients with nontraumatic chest pain were included in this retrospective study.Of them 414 patients underwent the conventional TRO-CTA scanning while 1 068 patients underwent TRO-CTA that included the abdominal aorta(TRO-CTAwAA)under the request of clinicians.All scanning parameters were the same,except the scanning range for the third phase in TRO-CTA:conventional TRO-CTA covered only the thoracic aorta,while TRO-CTAwAA extended to the entire aorta.Patient etiology was investigated and the detection rates of major vessel abnormalities(aortic dissection,aneurysm,penetrating ulcer,intramural hematoma,vascular occlusion,and thrombosis)between the two groups was compared using chi square tests.The radiation dose(CTDIvol and DLP)and scanning time between the two groups were compared using analysis of variance(ANOVA).Results The TRO-CTAwAA had significantly higher detection rate of major artery abnormalities than the TRO-CTA group(35.1％vs.4.8％,P＜0.001).In the TRO-CTAwAA group,26.5％of the vascular anomalies were detected in both the thoracic and abdominal aortas,and another 8.6％were seen only in the abdominal aorta.With regard to the radiation dose between the two groups,the total DLP was significantly higher in the TRO-CTAwAA group than in the conventional TRO-CTA group(P＜0.001).The two groups did not significantly differ in scanning time(P=0.410).Conclusion TRO-CTA with scan range including the abdominal aorta significantly improves the detection rate for major vessel abnormalities in patients with chest pain without increasing the examination process.

Objective To evaluate the relationship between the pericoronary fat attenuation index(FAI)and the image reconstruction parameters of computed tomography(CT)coronary angiography,including reconstruction kernel,iterative reconstruction algorithm and image thickness.Methods Forty-four CT coronary angiography scans were prospectively enrolled.All scans were reconstructed by three means as follows:① Four different kernels(Soft_AA,Soft_BA,Soft_CA,and Soft_DA,sharpness from low to high)as the iterative reconstruction algorithm(KARL5)and image thickness(0.5 mm)remained unchanged.② Filtered back projection(FBP)and iterative reconstruction kernel(KARL5)as the kernel and image thickness(0.5 mm)remained unchanged.③ Different image thickness(0.5 mm and 1 mm)as the kernel(Soft_AA)and iterative reconstruction algorithm(KARL5)remained unchanged.The FAI of left anterior descending artery(LAD),left circumflex artery(LCX),and right coronary artery(RCA)was calculated using a dedicated software.Paired t-test and analysis of variance were used for statistical analysis.Results For LAD,LCX and RCA:① The differences of FAI among different reconstruction kernels reached statistical significance(P＜0.001),and FAI decreased as the sharper kernel was used.③ Compared with FBP,the FAI of KARL5-reconstructed images significantly increased(P＜0.001).③ Compared with 0.5 mm,the FAI of images with 1.0 mm thickness significantly decreased(P＜0.001).Conclusion The kernel,iterative reconstruction algorithms,and image thickness all have a significant impact on the FAI of each coronary artery.When using FAI for clinical diagnosis,the effect of CT reconstruction parameters should be taken into account.

A new multifunctional fluorescent"turn-on"biosensor was constructed based on a guanine-rich hairpin probe and G-quadruplex/hemin DNAzyme.The probe was labeled with quencher and fluorescein at 5′and 3′terminus,respectively.In the absence of the target,the probe form hairpin structure and the fluorescence of the fluorescein was quenched by the quencher.However,in the presence of the target,the hairpin structure transformed to G-quadruplex and the fluorescence was recovered.By monitoring the fluorescence of the probe before and after combining with the target,both hemin and hemoglobin were detected rapidly and conveniently with high sensitivity.The limit of detection for hemin and hemoglobin were estimated to be 283 pmol/L and 109 pmol/L,respectively.The specific interaction between the DNA probe and hemin were investigated via absorption and fluorescence spectra.Furthermore,L-cysteine was detected with naked eyes based on the peroxidase-like activity of the new G-quadruplex/hemin DNAzyme.The limit of detection for L-cysteine was estimated to be 3.6 μmol/L,which was lower than the normal level of intracellular L-cysteine(30-200 μmol/L).The method developed here was rapid,simple and sensitive for detection of hemin,hemoglobin and L-cysteine,demonstrating great potential in bioanalysis,drug screening,and disease diagnosis.

To investigate the levels and clinical significance of serum microRNA ( miR) -146a, miR-145, T-helpertype17 (Th17)/regulatory T cell (Treg) in children with respiratory syncytial virus (RSV) infectious pneumonia. The clinical data of 200 children with RSV infectious pneumonia admitted to Nantong Maternal and Child Health Hospital from June 2020 to June 2023 were retrospectively collected as the study group. At the same time, 200 children with mycoplasma pneumonia were selected as the common pneumonia group and 200 healthy children were selected as the healthy group. The levels of serum inflammatory factors [interleukin-6 (IL-6), interferon-γ (IFN-γ), tumor necrosis factor-α (TNF-α)] were detected by enzyme-linked immunosorbent assay. The expression levels of serum miR-146a and miR-145 were detected by RT-qPCR. The levels of Th17/Treg were detected by flow cytometry. The levels of miR-146a, miR-145, Th17/Treg and serum inflammatory factors were compared among the three groups. Pearson method was used to analyze the correlation between miR-146a, miR-145, Th17/Treg and serum inflammatory factors in children with RSV infectious pneumonia. The receiver operating characteristic (ROC) curve was drawn to analyze the diagnostic value of miR-146a, miR-145, Th17/Treg in children with respiratory syncytial virus infection pneumonia. The results showed that in the study group, miR-146a (2.01±0.58), miR-145 (1.81±0.46), Th17/Treg (1.09±0.31), IL-6 (7.82±2.11) ng/L and TNF-α (9.82±2.96) ng/L were higher than those in the common pneumonia group miR-146a (1.49±0.42), miR-145 (1.43±0.31), Th17/Treg (0.77±0.24), IL-6 (5.89±1.32) ng/L, TNF-α (7.34±2.32) ng/L and healthy group miR-146a (1.25±0.19), miR-145 (1.19±0.16), Th17/Treg (0.38±0.09), IL-6 (4.52±1.04) ng/L, TNF-α (5.39±1.07)ng/L. The levels of the above indexes in the common pneumonia group were higher than those in the healthy group, and the differences were statistically significant ( F=183.543, 175.938, 617.182, 226.657, 193.459, P<0.05). In the study group, IFN-γ (14.18±3.25) pg/ml was lower than that in the control group (19.52±5.13) pg/ml, but higher than that in the healthy group (9.77±2.40) pg/ml, and the difference was statistically significant ( F=335.432, P<0.05). Pearson correlation analysis showed that miR-146a, miR-145 and Th17/Treg were positively correlated with IL-6 and TNF-α ( P<0.05), but negatively correlated with IFN-γ ( P<0.05). ROC curve results showed that the area under the curve (AUC) of miR-146a, miR-145 and Th17/Treg in the diagnosis of RSV infectious pneumonia was 0.767, 0.762 and 0.790, respectively, while the combined detection of the three was 0.904. In conclusion, the levels of miR-146a, miR-145 and Th17/Treg are highly expressed in children with RSV infectious pneumonia, and are closely related to the inflammatory response of children. The combined detection of the three may have certain application value in the auxiliary diagnosis of RSV infectious pneumonia.
