Objectives:To evaluate the diagnostic value of echocardiography in unroofed coronary sinus syndrome(UCSS)with endocardial cushion defect(ECD). Methods:The echocardiographic data of 43 patients of UCSS with ECD who underwent surgical treatment in our hospital from July 2017 to May 2022 were retrospectively analyzed.The diagnostic accuracy was evaluated by comparing the echocardiographic findings with the intraoperative exploration results. Results:According to Kirklin and Barratt-Boyes classification,there were 26 cases of type Ⅰ(60.5%),9 cases of type Ⅱ(20.9%),2 cases of type Ⅲ(4.7%),4 cases of type Ⅳ(9.3%),and 2 cases of type Ⅲ combined with type Ⅳ(4.7%).There were 26 cases(60.5%)of partial ECD,7 cases(16.3%)of intermediate ECD,10 cases(23.3%)of total ECD.Twenty two cases(51.2%)were associated with single atrium.Twenty seven cases(62.8%)were associated with persistent left superior vena cava(PLSVC).Other coexisting complicated malformations were as follows:2 cases of double outlet of right ventricle,1 case of pulmonary atresia,1 case of total anomalous pulmonary venous connection,and 1 case of aplenia syndrome.The coexisting simple malformations included 4 cases of ostium secundum atrial septal defect,2 cases of ventricular septal defect,3 cases of patent ductus arterial,and 6 cases of patent foramen ovale.Other abnormalities included 5 cases of absence of hepatic segment of inferior vena cava,1 case of hypoplasia of right superior vena cava,1 case of absence of right superior vena cava,3 cases of cor triatriatum,1 case of isolated levocardia,1 case of mirror image dextrocardia,4 cases of right aortic arch.Of the 43 patients,30(69.8%)were correctly diagnosed by preoperative echocardiography and 13(30.2%)by intraoperative exploration.UCSS was misdiagnosed as inferior vena cava type sinus septal defect and PLSVC was missed in 1 case.UCSS was missed in 12 cases,and PLSVC was missed in 3 cases of them. Conclusions:Diagnosis UCSS with ECD by echocardiography is valuable and challenging.It is necessary to strengthen the understanding of the embryonic development and pathological anatomy characteristics of these malformations to improve the diagnostic accuracy.

Objective To investigate the mechanism that mediates the inhibitory effect of Xinfeng Capsule(XFC)on interleukin(IL)-1β-induced impairment of chondrocytes.Methods XFC-medicated serum was collected from SD rats with XFC gavage,and its optimal concentration for chondrocyte treatment was determined using Cell Counting Kit-8 assay and flow cytometry.Dual luciferase reporter analysis was performed to analyze the targeting relationship between miR-502-5p and TRAF2.In cultured human chondrocytes induced with IL-1β,the effects of transfection with miR-502-5p inhibitor and XFC-medicated serum,alone or in combination,on expression levels of IL-1β,tumor necrosis factor-α(TNF-α),IL-4,and IL-10 were examined with ELISA,and the changes in the expressions of collagen type Ⅱ alpha 1(COL2A1),matrix metalloproteinase 13(MMP13),adisintegrin and metalloproteinase with thrombospondin motifs 5(ADAMTS5),and miR-502-5p/TRAF2/NF-κB axis gene expression were detected using RT-qPCR,Western blotting,and immunofluorescence assay.Results In cultured human chondrocytes,treatment with IL-1β significantly decreased the cell viability,increased cell apoptosis rate,lowered miR-502-5p,IL-4,IL-10,and COL2A1 expressions,and enhanced IL-1β,TNF-α,ADAMTS5,MMP13,TRAF2,and NF-κB p65 expressions(P<0.05),and these changes were significantly improved by treatment with XFC-medicated serum at the optimal concentration of 20％(P<0.05).Transfection of the chondrocytes with miR-502-5p inhibitor resulted in elevated expressions of IL-1β,TNF-α,ADAMTS5,MMP13,TRAF2,and NF-κB p65 and lowered expressions of miR-502-5p,IL-4,IL-10,and COL2A1,and XFC-medicated serum obviously reversed the effects of miR-502-5p inhibitor.Conclusion XFC can inhibit IL-1β-induced inflammatory response and ECM degradation in cultured human chondrocytes possibly by regulating the miR-502-5p/TRAF2/NF-κB axis.

Panax notoginseng is an ancient Chinese medicinal plant that has great clinical value in regulating cardiovascular disease in China. As a single component of panax notoginosides, notoginsenoside R1 (NGR1) belongs to the panaxatriol group. Many reports have demonstrated that NGR1 exerts multiple pharmacological effects in ischemic stroke, myocardial infarction, acute renal injury, and intestinal injury. Here, we outline the available reports on the pharmacological effects of NGR1 in ischemia-reperfusion (I/R) injury. We also discuss the chemistry, composition and molecular mechanism underlying the anti-I/R injury effects of NGR1. NGR1 had significant effects on reducing cerebral infarct size and neurological deficits in cerebral I/R injury, ameliorating the impaired mitochondrial morphology in myocardial I/R injury, decreasing kidney injury molecule-1 and neutrophil gelatinase-associated lipocalin in renal I/R injury and attenuating jejunal mucosal epithelium injury in intestinal I/R injury. The various organ anti-I/R injury effects of NGR1 are mainly through the suppression of oxidative stress, apoptosis, inflammation, endoplasmic reticulum stress and promotion of angiogenesis and neurogenesis. These findings provide a reference basis for future research of NGR1 on I/R injury.

Objective:To investigate the alterations in soft tissue morphology and thickness in the mid-face region of patients with cleft lip and palate (UCLP) secondary to maxillofacial deformity following Le Fort I osteotomy.Methods:A total of 22 patients (16 males and 6 females aged from 17 to 28 years with an average of 20 years) diagnosed with cleft lip and palate secondary to maxillofacial deformity were collected from the Wuhan University Hospital of Stomatology from July 2012 to August 2020. All patients underwent Le Fort I osteotomy. CBCT scans were obtained at T0 (3 days before surgery), T1 (7 days after surgery), and T2 (1 year after surgery). The Dolphin11.95 software and 3D Slicer software were utilized to measure and analyze the soft tissue near the mid-face osteotomy line. Differences in soft tissue thickness before and after surgery were compared.Results:Before and after the operation, the soft tissue thickness at P3, P5, P6, and P8 on the affected side was thicker than that on the healthy side, and the difference was statistically significant, with a P-value of <0.05. At P5, P6, P7, P8, and P9 below the osteotomy line at T2-T0, the degree of postoperative thinning on the affected side was more apparent than that on the healthy side, and there was statistical significance at P6 ( P<0.05). The postoperative soft tissue asymmetry in the Ck region was improved compared with the preoperative one. The preoperative average protruding of the affected side was 0.63 compared with the healthy side, and the postoperative value was 0.17. The preoperative and postoperative Mann-Whitney U tests showed significantly statistical difference. Conclusions:After Le Fort I osteotomy, the facial asymmetry of patients with unilateral cleft lip and palate secondary to maxillofacial deformity is improved. However, there is still a difference in the soft tissue thickness between the healthy side and the affected side, and the change in soft tissue thickness on the affected side is more significant than that on the healthy side.

Objectives To analyze the risk factors and their predictive value for postoperative hypoxemia in Type-A aortic dissection(TAAD).Methods A single-center retrospective study was conducted among 146 consecutive patients diagnosed as TAAD and undergone aortic arch surgery from January 2018 to June 2021 in Nanfang Hospital of Southern Medical University.According to the lowest postoperative PaO2/FiO2 ratio within 24 hours,the patients were classified into two groups:hypoxemia group(PaO2/FiO2≤200 mmHg)and non-hypoxemia group(PaO2/FiO2>200 mmHg).The difference of preoperative oxygen index,duration of mechanical ventilation and mortality in hospital were analyzed between the two groups.The independent risk factors for postoperative hypoxemia were evaluated by multivariate logistic regression and the predictive value was analyzed by receiver operator character(ROC)curves.Results For TAAD patients,the incidence of postoperative hypoxemia was 45.9%.Compared to non-hypoxemia group,hypoxemia group exhibited longer duration of mechanical ventilation(P<0.001)and longer intensive care unit(ICU)length of stay(P<0.05).Moreover,patients with hypoxemia presented higher mortality during hospital(P=0.011).Multivariate regression analysis identified BMI as independent risk factor(OR=1.701,P<0.001)and preoperation PaO2/FiO2 ratio as protective factors for postoperative hypoxemia in patients with TAAD(OR=0.987,P=0.004).Area under the ROC curve of BMI was 0.848,the optimal cut-off point of BMI was 25.8 kg/m2.Area under the ROC curve of pre-operation PaO2/FiO2 ratio was 0.808,the optimal cut-off point of preoperation PaO2/FiO2 ratio was 265 mmHg.Conclusions BMI higher than 25.8 kg/m2 is an independent risk factor and preoperation PaO2/FiO2 ratio higher than 265 mmHg is a protective factor for postoperative hypoxemia in patients with TAAD.Subjects with hypoxemia had longer duration of mechanical ventilation,ICU stay and higher mortality.

Head and neck squamous cell carcinoma (HNSCC), as the most common type (>90%) of head and neck cancer, includes various epithelial malignancies that arise in the nasal cavity, oral cavity, pharynx, and larynx. In 2020, approximately 878 ‍ 000 new cases and 444 000 deaths linked to HNSCC occurred worldwide (Sung et al., 2021). Due to the associated frequent recurrence and metastasis, HNSCC patients have poor prognosis with a five-year survival rate of 40%-50% (Jou and Hess, 2017). Therefore, novel prognostic biomarkers need to be developed to identify high-risk HNSCC patients and improve their disease outcomes.

OBJECTIVES: To study the correlation between CT imaging features of acceleration and deceleration brain injury and injury degree. METHODS: A total of 299 cases with acceleration and deceleration brain injury were collected and divided into acceleration brain injury group and deceleration brain injury group according to the injury mechanism. Subarachnoid hemorrhage (SAH) and Glasgow coma scale (GCS), combined with skull fracture, epidural hematoma (EDH), subdural hematoma (SDH) and brain contusion on the same and opposite sides of the stress point were selected as the screening indexes. χ² test was used for primary screening, and binary logistic regression analysis was used for secondary screening. The indexes with the strongest correlation in acceleration and deceleration injury mechanism were selected. RESULTS: χ² test showed that skull fracture and EDH on the same side of the stress point; EDH, SDH and brain contusion on the opposite of the stress point; SAH, GCS were correlated with acceleration and deceleration injury (P<0.05). According to binary logistic regression analysis, the odds ratio (OR) of EDH on the same side of the stress point was 2.697, the OR of brain contusion on the opposite of the stress point was 0.043 and the OR of GCS was 0.238, suggesting there was statistically significant (P<0.05). CONCLUSIONS EDH on the same side of the stress point, brain contusion on the opposite of the stress point and GCS can be used as key indicators to distinguish acceleration and deceleration injury mechanism. In addition, skull fracture on the same side of the stress point, EDH and SDH on the opposite of the stress point and SAH were relatively weak indicators in distinguishing acceleration and deceleration injury mechanism.
