0.05). Expression of MDR1 had a positive ~correlation with mutant p53 accumulation and HER2 expression(P0.05 ).In univariate analyses,TNM staging, axillary lymph node metastasis, mutant p53 accumulation, and HER2 over-expression were negatively correlated with DFS and OS, and MDR1 over-expression significantly reduced OS but not DFS. In multivariate analysis, axillary lymph node metastasis, over-expression of MDR1 and HER2 were independent risk factors for prognosis. Conclusions ~Induction of multidrug resistance and poor response to chemotherapy and endocrinotherapy may be the chief reasons for poor prognosis of breast cancer with mutant p53 accumulation, and HER2 and MDR1 over-expression. ~Determination of the above genes′expression in breast cancer tissue can be of use in deciding the degree of ~malignancy , metastasis phenotype and prognosis of brest cancer. Increasing anthracycline dose may increase the ~overall response rate to chemotherapy and improve prognosis in patients with mutant p53 accumulation, HER2 and MDR1 over-expression, especially HER2 over-expression.

Objective:To investigate the effect of optimized construction of green channel under plan-do-check-action (PDCA) on shortening the door-to-needle time (DNT) and improving early neurological improvement in patients with acute ischemic stroke (AIS) treated with intravenous thrombolysis.Methods:The clinical data of 120 patients with AIS treated with intravenous thrombolysis from June 2018 to September 2019 in Liangxiang Teaching Hospital of Capital Medical University were retrospectively analyzed. Among them, 60 patients were admitted to hospital before optimized as non-optimized group, and 60 patients were admitted to hospital after optimized as optimized group. The time from visit to CT examination completion, time from CT examination completion to informed consent, time from informed consent to intravenous thrombolysis, DNT, DNT ≤ 60 min ratio, National Institutes of Health stroke scale (NIHSS) score 2 h after intravenous thrombolysis and at discharge from hospital, early neurological improvement (ENI) rate, hospital stays, adverse outcomes and mortality were compared between 2 groups.Results:The time from CT examination completion to informed consent and DNT in optimized group were significantly shorter than those in non-optimized group: 29 (14, 36) min vs. 37 (21, 54) min, 55 (45, 67) min vs. 76 (54, 93) min, the DNT ≤ 60 min ratio was significantly higher than that in non-optimized group: 68.3% (41/60) vs. 35.0% (21/60), the ENI rate was significantly lower than that in non-optimized group: 28.3% (17/60) vs. 46.7% (28/60), and there were statistical differences ( P<0.05 or<0.01). There were no statistical differences in the time from visit to CT examination completion, time from informed consent to intravenous thrombolysis, NIHSS score 2 h after intravenous thrombolysis, hospital stays, NIHSS score at discharge from hospital, adverse outcomes rate and mortality between 2 groups ( P>0.05). Conclusions:The optimized construction of green channel under PDCA can effectively shorten the DNT of intravenous thrombolysis in patients with AIS, and may be significantly important for improving the long-term prognosis of patients.

Objective To analyze the clinical features and prognosis of adult optic neuritis patients with positive serum myelin oligodendrocyte glycoprotein antibody (MOG-ON) or aquaporin 4 antibody (AQP4-ON).Methods A retrospective study. From December 2015 to February 2018, in the Beijing Chaoyang Hospital of Capital Medical University and Chinese PLA General Hospital, 162 eyes of 132 patients with positive serum MOG antibody and AQP4 were included in the study. There were 42 MOG-ON patients (49 eyes, 31.8%), 90 AQP4-ON patients (113 eyes, 68.2%). The clinical features of optic neuritis (annual recurrence frequency, incidence of optic disc edema), brain and optic nerve enhanced MRI, serum autoimmune antibodies and cerebrospinal fluid test results were compared between MOG-ON and AQP4-ON patients. All patients were treated with intravenous methylprednisolone sodium succinate in the acute phase and then switched to oral prednisone acetate tablets. The average follow-up time was 15 months. The glucocorticoid dependence, visual prognosis, spinal cord symptoms, and myelitis at the last follow-up were comparatively analyzed between MOG-ON and AQP4-ON patients. The comparison of the count data was performed by χ2 test, and the measurement data were compared byt test.Results Compared with AQP4-ON patients, MOG-ON patients had higher annual recurrence frequency (t=3.760,P=0.005), higher incidence of optic disc edema (χ2=14.777,P<0.001), higher incidence of hormone dependence (χ2=25.496,P<0.001), and better visual prognosis (χ2=28.759, P<0.001). MOG-ON patients were more likely to involve the optic nerve, AQP4-ON patients were more likely to involve the optic chiasm and the optic tract. There was a significant difference in the location of lesions between MOG-ON and AQP4-ON patients (χ2= 5.447,P= 0.015). The proportion of AQP4-ON patients with autoimmune antibodies was significantly higher than that of MOG-ON patients (χ2 = 20.453,P<0.001). The results of cerebrospinal fluid test showed that the white blood cell count of patients with MOG-ON and AQP4-ON were within the normal range, but the IgG level of AQP4-ON patients was significantly higher than that of MOG-ON patients (t=8.669,P<0.001). At the last follow-up, there were 7 and 29 patients of myelitis in MOG-ON and AQP4-ON patients respectively (χ2=3.494,P=0.046).Conclusions The clinical characteristics of MOG-ON were different from AQP4-ON. The incidence of optic disc edema and recurrence rate were higher, but the proportion of autoimmune antibodies was lower. MOG-ON was more likely to show hormone dependence, but the visual prognosis was better. AQP4-ON was easily involved in optic chiasm and optic tract, and the incidence of myelitis was higher.

PURPOSE: Tripartite-motif-containing protein 56 (TRIM56) has been found to exhibit a broad antiviral activity, depending upon E3 ligase activity. Here, we attempted to evaluate the function of TRIM56 in multiple myeloma (MM) and its underlying molecular basis. MATERIALS AND METHODS: TRIM56 expression at the mRNA and protein level was measured by qRT PCR and western blot analysis. 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and flow cytometry analysis was performed to investigate the effect of TRIM56 on MM cell proliferation and apoptosis. The concentrations of interferon (IFN)-β, interleukin (IL)-6, and tumor necrosis factor-α in MM cell culture supernatants were detected with respective commercial ELISA kits. Western blot was employed to determine the effect of TRIM56 on toll-like receptor 3 (TLR3)/toll-IL-1 receptor (TIR) domain-containing adaptor inducing IFN-β (TRIF) signaling pathway. RESULTS: TRIM56 expression was prominently decreased in MM cells. Poly (dA:dT)-induced TRIM56 overexpression in U266 cells suppressed proliferation, induced apoptosis, and enhanced inflammatory cytokine production, while TRIM56 knockdown improved growth, diminished apoptosis, and inhibited inflammatory cytokine secretion in RPMI8226 cells. Moreover, TRIM56 knockdown blocked TLR3 signaling pathway. Furthermore, poly (I:C), a TLR3 agonist, markedly abolished TRIM56 depletion-induced increase of proliferation, decrease of apoptosis, and reduction of inflammatory factor in MM cells. CONCLUSION: TRIM56 may act as a tumor suppressor in MM through activation of TLR3/TRIF signaling pathway, contributing to a better understanding of the molecular mechanism of TRIM56 involvement in MM pathogenesis and providing a promising therapy strategy for patients with MM.

Objective:To explore the serum tenascin-C levels in patients with acute ST-segment elevation myocardial infarction (STEMI) and its impact on the long-term prognosis.Methods:One hundred and thirteen STEMI patients who were admitted to the Department of Cardiology of the First Affiliated Hospital of Dalian Medical University and successfully underwent emergency PCI from June 2015 to June 2016 were included in this prospective study. The serum tenascin-C levels were measured during hospitalization, and the patients were divided into tenascin-C ≥ 120 μg/L group and tenascin-C<120 μg/L group according to the serum tenascin-C level. Major adverse cardiovascular events (MACE) were observed during the 5 years follow up in all patients. According to the incidence of MACE, the patients were divided into MACE group and non-MACE group, and the predictive factors of MACE were analyzed. Continuous variables were presented as the mean±standard deviation and compared with the Student′s t-test. Categorical variables were presented as percentages and compared with the Chi-square test or Fisher′s exact test. Receiver operating characteristic (ROC) curve was used to analyze the value of serum tenascin-C level in predicting MACE in STEMI patients. Kaplan Meier survival analysis was used to compare the incidence of MACE between two groups. Cox proportional hazards regression model was used to analyze the risk factors of MACE during the 5 years follow up.Results:The serum tenascin-C levels in the STEMI patients increased on the first day after the onset of disease (46.5±24.8 μg/L), peaked on the third day (97.5±41.2 μg/L), and then gradually decreased. All patients were followed up for 5 years. There were 37 cases of MACE, including 4 cases of cardiac death (3.5%), 14 cases of heart failure (12.4%), 14 cases of recurrent myocardial infarction or revascularization (12.4%), and 5 cases of stroke (4.4%). For prediction of MACE, the area under the curve of the serum TN-C level was 0.953 (95% CI 0.918-0.988, P<0.05), which was thus a valuable biomarker in predicting MACE for STEMI patients. The incidence of MACE in the group of tenascin-C≥120 μg/L group was higher than that in the group of tenascin-C<120 μg/L group (86.4% [19/22] vs 19.8% [18/91]), and Kaplan-Meier survival analysis showed that the difference was statistically significant ( P<0.05). Cox proportional hazards model analysis showed that serum tenascin-C level was an independent predictor of MACE for STEMI patients during the 5 years follow-up ( HR=1.007, 95% CI 1.001-1.012, P<0.05). In addition, other variables including high sensitivity C-reactive protein ( HR=1.028, 95% CI 1.007-1.049, P<0.05), and cardiac troponin Ⅰ ( HR=1.004, 95% CI 1.000-1.008, P<0.05) were also found to be the independent predictors of MACE. Conclusions:The serum tenascin-C levels in STEMI patients increased significantly during the acute disease phase. Detecting the serum tenascin-C levels is valuable for predicting MACE in STEMI patients, and serum tenascin-C is an independent predictor of MACE in STEMI patients during the long-term follow-up period after acute myocardial infarction.

Objective:To investigate imaging characteristics of papulopustular rosacea (PPR) by high-frequency ultrasound combined with color Doppler flow imaging.Methods:From August 2021 to August 2022, 30 patients with PPR were enrolled from the Department of Dermatology, the First Affiliated Hospital of Baotou Medical College in the Inner Mongolia Autonomous Region, and 30 healthy volunteers served as controls. The 22-MHz high-frequency ultrasound combined with color Doppler blood flow imaging was performed to measure the skin thickness, echo and blood flow parameters at the cheek, and the ultrasound results were compared between the two groups. Comparisons between groups were conducted by using t test or chi-square test. The diagnostic value was analyzed using the area under the curve (AUC) in the receiver operating characteristic (ROC) curve. Results:In the case group, there were 12 males and 18 females, and their ages ranged from 22 to 65 years (42.3 ± 12.8 years) ; in the control group, there were 10 males and 20 females, and their ages ranged from 24 to 62 years (41.0 ± 8.4 years) . The epidermal and dermal thicknesses at the cheek were significantly higher in the case group (132.64 ± 12.29 μm, 1 812.29 ± 85.52 μm, respectively) than in the control group (104.34 ± 14.45 μm, 1 671.77 ± 146.55 μm, respectively, both P < 0.05) . High-frequency ultrasound images showed that the case group was mainly characterized by irregular hypoechoic areas in the cheek dermis (80%) , while banded moderately echoic areas were common in the cheek dermis in the control group (90%) ; subepidermal low-echogenic bands and dermal irregular hypoechoic areas were more likely to appear in the case group than in the control group (93.33% vs. 43.33%, 80% vs. 10%, respectively, both P < 0.001) . Compared with the control group, the case group showed a significantly increased proportion of patients with abundant blood flow signals (93.3% vs. 10%, P < 0.05) , and significantly increased blood vessel diameters (1.60 ± 0.42 mm vs. 0.95 ± 0.32 mm, P < 0.05) ; there was no significant difference in peak systolic blood flow velocity and vascular resistance index between the two groups (both P > 0.05) . The AUC of high-frequency ultrasound combined with color Doppler flow imaging quantitative parameters (including epidermal thicknesses, dermal thicknesses, and blood vessel diameters) was 0.989 (95% CI: 0.970 - 1.000) for the diagnosis of PPR, and the sensitivity and specificity were both 96.7%, which were higher than those of single parameter-based diagnostic model. Conclusion:High-frequency ultrasound combined with color Doppler flow imaging can help improve the accuracy of the diagnosis of PPR, by accurately and non-invasively measuring skin thickness and blood flow parameters.

BACKGROUND:
Limited data are available on the comparison of clinical outcomes of complete vs. incomplete percutaneous coronary intervention (PCI) for patients with chronic total occlusion (CTO) and multi-vessel disease (MVD). The study aimed to compare their clinical outcomes.
METHODS:
A total of 558 patients with CTO and MVD were divided into the optimal medical treatment (OMT) group ( n = 86), incomplete PCI group ( n = 327), and complete PCI group ( n = 145). Propensity score matching (PSM) was performed between the complete and incomplete PCI groups as sensitivity analysis. The primary outcome was defined as the occurrence of major adverse cardiovascular events (MACEs), and unstable angina was defined as the secondary outcome.
RESULTS:
At a median follow-up of 21 months, there were statistical differences among the OMT, incomplete PCI, and complete PCI groups in the rates of MACEs (43.0% [37/86] vs. 30.6% [100/327] vs. 20.0% [29/145], respectively, P = 0.016) and unstable angina (24.4% [21/86] vs. 19.3% [63/327] vs. 10.3% [15/145], respectively, P = 0.010). Complete PCI was associated with lower MACE compared with OMT (adjusted hazard ratio [HR] = 2.00; 95% confidence interval [CI] = 1.23-3.27; P = 0.005) or incomplete PCI (adjusted HR = 1.58; 95% CI = 1.04-2.39; P = 0.031). Sensitivity analysis of PSM showed similar results to the above on the rates of MACEs between complete PCI and incomplete PCI groups (20.5% [25/122] vs. 32.6% [62/190], respectively; adjusted HR = 0.55; 95% CI = 0.32-0.96; P = 0.035) and unstable angina (10.7% [13/122] vs. 20.5% [39/190], respectively; adjusted HR = 0.48; 95% CI = 0.24-0.99; P = 0.046).
CONCLUSIONS
For treatment of CTO and MVD, complete PCI reduced the long-term risk of MACEs and unstable angina, as compared with incomplete PCI and OMT. Complete PCI in both CTO and non-CTO lesions can potentially improve the prognosis of patients with CTO and MVD.
