Objective:To investigate the clinical value of prospective ECG-gated high-pitch protocol scanning of third generation DSCT in the diagnosis of pediatric congenital heart disease (CHD).Methods:A total of 243 children with confirmed CHD who were expected to undergo surgical treatment were prospectively collected and randomly divided evenly into 3 groups, with first group for prospective ECG-gated high-pitch scanning in third generation DSCT (Flash 3rd), second group for prospective ECG-gated high-pitch scanning in second generation DSCT (Flash 2nd) and third group for prospective sequential scanning in third generation DSCT (Sequence 3rd). The SD value and SNR of aortic root and pulmonary artery of each child were recorded. The 5-point system is adopted with subjective scoring. Based on the result of operation, the diagnosis accuracy in 3 groups was analyzed. Results:The E values in Flash 3rd, Flash 2nd and Sequence 3rd group were 0.24 (0.19, 0.27), 0.11 (0.10, 0.14) and 0.44 (0.39, 0.48) mSv ( H=207.04, P<0.05), respectively. Subjective scores of group Flash 3rd and Sequence 3rd were significantly higher than that of group Flash 2nd [4 (4, 4) vs. 4(3, 4) vs. 3(3, 3), H=124.05, P<0.05] and no difference between these two groups. SD value of aortic root and pulmonary artery of group Flash 3rd and Sequence 3rd were significantly lower than that of group Flash 2nd( H= -40.27-33.38, P<0.05). SNR of aortic root and pulmonary artery of group Flash 3rd was significantly higher than that of group Flash 2nd and Sequence 3rd ( H=-0.90-51.42, P<0.05). Diagnosis accuracy of intracardiac malformation for group Flash 2nd was significantly lower than that of Flash 3rd and Sequence 3rd (77.7%, 90.9%, 88.9%, K=9.36, P<0.05), and there was no significant difference between the latter two groups. There was no difference in diagnosis accuracy of extracardiac malformation among 3 groups (88.6%, 94.8%, 92.2%, K=3.11, P=0.21). Conclusions:The prospective ECG-gated high-pitch scanning in third generation DSCT can take into account radiation dose and image quality, which has important clinical value in the diagnosis of CHD.

Objective:To explore the methods and clinical effects of reconstructing facial and cervical scars with expanded flaps based on the "MLT" principle.Methods:The study was a retrospective observational study. From January 2019 to May 2022, 74 patients with facial and cervical scars after burn or trauma injuries who met the inclusion criteria were admitted to Xiangya Hospital of Central South University, including 38 males and 36 females, aged from 5 to 58 years, including 24 patients with simple facial involvement, 24 patients with simple cervical involvement, and 26 patients with both facial and cervical involvement, with scar area ranging from 12 to 145 cm2. By following the "MLT" principle (color and texture similar to the face; flap area large enough to reconstruct the entire defect; skin tissue thin enough to transmit the expression, so as to facilitate the shape of the face and five features); in the stage Ⅰ surgery, the skin and soft tissue expanders (hereinafter referred to as the expanders) were implanted, and in the stage Ⅱ surgery, the expander removal+scar resection+flap transplantation to repair the secondary wound was performed, and the wound in the donor area of flap was directly sutured. After operation, silicone gel preparation and laser therapy were used to prevent scar hyperplasia. The expansion ratio and time period of expanders, the occurrence of complications of skin and soft tissue expansion surgery, the type of flap used, and the survival of flap after the stage Ⅱ surgery were observed and recorded. The long-term effect of facial and cervical reconstruction and the recovery of donor area and recipient area of flap were evaluated during the postoperative follow-up after surgery.Results:The expansion ratio of 135 expanders ranged from 1.36 to 3.00 times, and the expansion time period ranged from 6 to 14 months. During skin and soft tissue expansion surgery, 8 patients had poor healing of incisions after expander placement, 7 patients had expander rupture, 5 patients had infection in incisions after expander placement, 3 patients had expander exposure, 2 patients had difficult filling the injection pot, and 1 patient had water leakage from the injection pot. Dorsal shoulder expanded flaps with double blood supply of transverse cervical artery and circumflex scapular artery were used in 8 patients, the expanded flaps of anterior transverse carotid artery perforator were used in 11 patients, the expanded flaps of internal thoracic artery perforator were used in 12 patients, tandem expanded flaps of upper chest and neck were used in 16 patients, dorsal thoracic artery perforator expanded flaps were used in 5 patients, and adjacent rotary propulsive expanded flaps were used in 22 patients. After the stage Ⅱ surgery, the flaps of 71 patients were completely survived. One patient had blood circulation disorder in the flap, and the flap survived after hyperbaric oxygen treatment. Necrosis occurred at the end of the flaps in 2 patients, which healed after dressing change. After the surgery, 42 patients were followed up for 3 to 24 months. The color, texture, and thickness of flaps were good and similar to the surrounding normal skin tissue in the recipient area, the appearance and function of the face and neck were significantly improved, and the wound location in the donor and recipient areas of flaps was concealed with slight scar formation.Conclusions:In the reconstruction of facial and neck scars, by following the "MLT" principle, the expanded flap was carefully designed before surgery, the local aesthetic features within the subunit are reconstructed during the stage Ⅱ surgery, and standard anti-scar treatment measures are actively adopted after surgery. After reconstruction, the color, texture, and thickness of flaps were close to the normal skin in face and neck, and the appearance and function of face and neck are significantly improved, with less linear scars left. It is beneficial to improve the therapeutic effect.

Objective:To investigate the optimal delay time in the quantitative assessment of myocardial fibrosis based on dual-energy CT extracellular volume fraction (DECT-ECV), using MRI as a reference.Methods:Thirty patients with confirmed or suspected of cardiomyopathy were prospectively enrolled in this study. All the patients underwent both cardiac DECT and MRI examination within one week. According to the imaging features of late gadolinium enhancement (LGE) on MRI, myocardial segments were classified into 3 types: ischemic LGE segments, non-ischemic LGE segments and negative LGE segments. According to the DECT delay time, the whole and segmental myocardium were divided into 3 groups: delay of 3 min (Group A), delay of 5 min (Group B) and delay of 7 min (Group C). Correlation and agreement between CT-ECV and MRI-ECV were performed on a basis of overall myocardium and segmental myocardium. Pearson or Spearman test was used for correlation analysis and Bland-Altman test was used for consistency analysis.Results:Thirty patients with 480 segments were finally included in our study. In the analysis based on overall myocardium, MRI-ECV was 33.12%±4.29%, and CT-ECV were 35.81%±4.48%, 36.02%±4.56%, and 36.58%±4.69% in Group A, B, and C, respectively. The agreement between DECT-ECV and MRI-ECV results was good, with the correlation coefficients of 0.878 (group A), 0.955 (Group B) and 0.947 (Group C) (all P<0.001). In the analysis based on segmental myocardium, as for the ischemic LGE myocardial segments, MRI-ECV was 34.60%(31.70%,39.40%), and CT-ECV were 37.50 (34.20, 41.90), 38.20%(36.20%, 40.60%)and 39.40%(35.50%,42.40%)in Group A, B, and C, respectively. The agreement between DECT-ECV and MRI-ECV results was good, with the correlation coefficients of 0.559, 0.695 and 0.682 (all P<0.001) for groups A, B and C, and as for non-ischemic LGE myocardial segments, MRI-ECV was 35.10% (32.68%, 38.70%), and CT-ECV were 38.15% (35.13%, 41.75%), 39.25% (35.78%, 42.20%) and 39.60% (35.88%,42.90%) in Group A, B, and C. The correlation coefficients of CMR-ECV and DECT-ECV of groups A, B and C were 0.531, 0.772 and 0.744 (all P<0.001), showing good agreement; as for negative LGE myocardial segments, MRI-ECV and CT-ECV of Group A, Group B, Group C were 28.50%(27.00%, 30.10%), 31.10%(28.70%, 34.60%), 31.30%(28.40%, 33.80%), 31.30%(29.20%, 34.80%). The correlation coefficients between MRI-ECV and DECT-ECV of group A, B and C were 0.273, 0.508 and 0.425 (all P<0.001), which also showed good agreement. Conclusions:DECT-ECV can be used for quantitative evaluation of myocardial histological features. DECT-ECV with a 5 min and 7 min delay shows good correlation and agreement with MRI-ECV. In order to make this technology more well-known and improve its application capability, our recommendation for clinical practice is a 5 min delay after contrast administration in clinical practice.

Objective To evaluate the effect of extracorporeal membrane oxygenation combined with intra-aortic balloon pump mechanical circulatory support for patients with cardiogenic shock complicating acute myocar-dial infarction during PCI process.Methods Patients with cardiogenic shock complicating myocardial infarction who underwent PCI in the hospital from January 2015 to December 2019 were selected.Those who were under support of extracorporeal membrane oxygenation combined with intra-aortic balloon pump were enrolled in the observation group,the patients under support of only intra-aortic balloon pump were selectedin the control group.The differ-ences of clinical features and prognosis were compared.Results A total of 40 patients were enrolled,11 were in the observation group and 29 in the control group.Compared with control group,more patients were complicated with old myocardial infarction(5/11 vs.2/29,P=0.016),more patients were diagnosed as non-ST elevated myocardial infarction(8/11 vs.11/29,P=0.049)and left ventricular ejecting fraction was lower[(38.5±10.10)vs.(48.55±8.86),P=0.01]in observation group.Moreover,the proportion of patients with EF＜35％was higher in the observation group(5/11 vs.3/29,P=0.01).The observation group has significantly higher rates of multi-vessel disease and Syntax scores compared to the control group(multi-vessel disease:10/11 vs.11/29,P=0.02;Syntax score:[(33.36±13.37)vs.(25.74±5.75),P=0.015];the observation group exhibited a higher proportion of patients achieving complete revascularization(9/11 vs.8/29,P=0.002).Mechanical complications were higher in observation group(6/11 vs.5/29,P=0.02),The survive rate in observation group is higher than that in control group(91.00％vs.55.17％,P=0.03)at one-year follow-up.Conclusion Compared with only IABP,ECMO com-bined with IABP hemodynamic support during PCI process for patients with cardiogenic shock complicating acute myocardial infarction enjoys more complete revascularization and better mortality outcome,although it has rela-tively higher mechanical complications.

Objective:To explore the protective effect of emodin on D-galactosamine (D-GalN)/lipopolysaccharide (LPS)-induced acute liver injury and its mechanism.Methods:A total of 40 male BALB/c mice were randomly (random number) divided into 5 groups ( n=8 in each group): the control group, the emodin group, the D-GalN/LPS group, the emodin+D-GalN/LPS group and the 3-MA+emodin+D-GalN/LPS group. D-GalN (700 mg/kg) and LPS (10 μg/kg) were intraperitoneally injected to induce acute liver injury in mice. Autophagy inhibitor 3-MA (15 mg/kg) and/or emodin (20 mg/kg) were intraperitoneally injected 30 min before the liver injury model. The animals were sacrificed under anaesthesia 6 h after D-GalN/LPS challenge, blood samples and liver tissues were collected. The levels of alanineaminotransferase (ALT) and aspartateaminotransferase (AST) in serum, and myeloperoxidase (MPO) activity of liver tissues were determined by colorimetric quantitative method; the levels of tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6) were measured by ELISA; the expression of LC3-II and Beclin 1 in the liver tissues were evaluated by Western blot; the pathological changes of liver was evaluated by HE staining. Animal survival rate was also analyzed. The one-way ANOVA was use to compare quantitative data, SNK- q test was used for pairwise comparison between two groups, and Games-Howell test was used when homogeneity of variance were not met. Results:Compared with the control group, the levels of ALT, AST, TNF-α, IL-6 and MPO activity [(2 476.80 ± 263.14) U/L, (271.71 ± 47.15) U/L, (537.92 ± 89.35) pg/mL, (169.74 ± 25.52) pg/mL, and (1.37 ± 0.22) U/mg] were obviously increased in the D-GalN/LPS group ( P<0.05). Compared with the D-GalN/LPS group, the levels of ALT, AST, TNF-α, IL-6 and MPO activity [(1 248.01 ± 380.70) U/L, (142.59 ± 34.63) U/L, (288.91 ± 67.21) pg/mL, (61.83 ± 13.64) pg/mL, and (0.80 ± 0.21) U/mg] were obviously decreased in the emodin+ D-GalN/LPS group ( P<0.05). Compared with the D-GalN/LPS group, the histopathological abnormalities in liver tissue were significantly alleviated and the survival rate of mice was improved in the emodin+ D-GalN/LPS group. Compared with the control group, the expression of LC3-II and Beclin1 was decreased in the liver tissue in the D-GalN/LPS group, while compared with the D-GalN/LPS group, the expression of LC3-II and Beclin1 was increased in the emodin+ D-GalN/LPS group. With co-administration of 3-MA, the protective effects of emodin in acute liver injury were reversed, the levels of AST, ALT, TNF-α, IL-6, and MPO [(2 398.78 ± 233.57) U/L, (242.79 ± 43.46) U/L, (505.07 ± 67.89) pg/mL, (151.46 ± 14.11) pg/mL, and (1.27 ± 0.15) U/mg] were increased, and the pathological damage of liver tissue was aggravated. Conclusions:Emodin alleviates D-GalN/LPS-induced acute liver injury in mice, which may be related to the activation of protein LC3-II, Beclin1 and restored autophagy.
