Objective:To evaluate the effects of pulmonary embolism response team (PERT) on the quality of care and clinical outcomes in patients with acute pulmonary embolism.Methods:This was a single-center retrospective cohort study. Patients with acute pulmonary embolism treated in Beijing Anzhen Hospital Affiliated to Capital Medical University from July 5, 2016 to July 4, 2018 were enrolled. Patients with acute pulmonary embolism who had traditional care from July 5, 2016 to July 4, 2017 (before the implementation of PERT) were classified as PERT pre-intervention group. Patients with acute pulmonary embolism who started PERT care from July 5, 2017 to July 4, 2018 were divided into the PERT intervention group. The diagnosis and treatment information of patients was collected through the electronic medical record system, and the quality of care (time from visit to hospitalization, time from hospitalization to anticoagulation initiation, time from visit to definitive diagnosis, total hospital stay, time in intensive care unit (ICU), hospitalization cost) and clinical outcomes (in-hospital mortality and incidence of bleeding) were compared between the two groups.Results:A total of 210 patients with acute pulmonary embolism, aged (63.3±13.7) years old, with 102 (48.6%) female patients were included. There were 108 cases in PERT pre-intervention group and 102 cases in PERT intervention group. (1) Quality of diagnosis and treatment: there was a statistical significance between the two groups in the distribution of time from diagnosis to definitive diagnosis ( P=0.002). Among them, the rate of completion of diagnosis within 24 hours after PERT intervention was higher than that before PERT intervention (80.4% (45/56) vs. 50.0% (34/68), P<0.001). The time from treatment to hospitalization was shorter than that before PERT intervention (180.0 (60.0, 645.0) min vs. 900.0 (298.0, 1 806.5) min, P<0.001). The total length of hospital stay was less than that before PERT intervention (12 (10, 14) d vs. 14 (11, 16) d, P=0.001). There was no statistical significance in the time from hospitalization to anticoagulant therapy, the length of ICU stay and hospitalization cost between the two groups (all P>0.05). (2) Clinical outcomes during hospitalization: There was no statistical significance in the incidence of hemorrhage and mortality between the two groups during hospitalization (both P>0.05). Conclusion:PERT has improved the efficiency of diagnosis and treatment of patients with acute pulmonary embolism and significantly shortened the total hospital stay, but its impact on clinical outcomes still needs further study.

OBJECTIVE: This study evaluated the effect of maximal oxygen pulse (O ₂P _max) on patients with chronic obstructive pulmonary disease (COPD) and confirmed the predictive effect on acute exacerbations of COPD (AECOPD). METHODS: This retrospective study included 91 participants who underwent cardiopulmonary exercise testing (CPET), lung function testing, a dyspnea scale assessment, and a 3-year follow-up. The participants were divided into two groups according to the O ₂P _max value. Exercise capacity, ventilatory conditions, gas exchange efficiency, and dyspnea symptoms were compared, and the correlations between O ₂P _max and these indices were evaluated. The ability of O ₂P _max to predict AECOPD was examined. RESULTS: Exercise capacity, ventilatory conditions, and gas exchange efficiency were lower, and dyspnea symptom scores were higher in the impaired O ₂P _max group ( P < 0.05). O ₂P _max was positively correlated with forced vital capacity (FVC)%, forced expiratory volume in 1 sec (FEV ₁)%, FEV ₁/FVC%, anaerobic threshold (AT), work rate (WR)%, aximal oxygen uptake (V̇O _2max)%, V̇O ₂/kg _max, V̇O ₂/kg _max%, WR _AT, WR _max, V̇O _2AT, V̇O _2max, and V̇ _Emax, and was negatively correlated with EqCO _2AT, and EqCO _2max ( P < 0.05). Most importantly, O ₂P _max could be used to predict AECOPD, and the best cut-off value was 89.5% (area under the curve, 0.739; 95% CI, 0.609-0.869). CONCLUSION O ₂P _max reflected exercise capacity, ventilation capacity, gas exchange capacity, and dyspnea symptoms in patients with COPD and may be an independent predictor of AECOPD.

Objective: To evaluate the efficacy of the Hodgkin lymphoma (HL)-2013 regimen in the treatment of children with HL, and to investigate the prognostic factors of childhood HL. Methods: Clinical data of 145 children (aged ≤18 years) with newly diagnosed HL, treated with HL-2013 regimen in 8 tertiary referral centers for childhood cancer from August 2011 to April 2021 were analyzed retrospectively. All the diagnosis were confirmed by histopathological morphology and immunohistochemical examination. The clinical characteristics and treatment outcomes were summarized, and the patients were divided into different groups according to clinical characteristics. Kaplan-Meier method was used for survival analysis, and the comparison of survival rates between groups was performed with Log-rank test. Results: Of the 145 cases, there were 115 males and 30 females, the age at diagnosis was 7.9 (5.8, 10.6) years. Cervical lymph node enlargement (114 cases, 78.6%) was the common symptom of the disease, and 57 patients (39.3%) were accompanied by large masses. The most common pathological classification was mixed cell type (93 cases, 64.1%). According to the Ann Arbor staging system, there were 9 cases of stage Ⅰ, 62 cases of stage Ⅱ, 45 cases of stage Ⅲ, 29 cases of stage Ⅳ. According to the risk stratification: there were 14 cases of low-risk group, 76 cases of medium-risk group and 55 cases of high-risk group. Of all patients, 68 cases (46.9%) achieved an early complete remission (CR) after 2 courses of chemotherapy, and the CR rate was 93.8% (136/145) after first-line treatment. Disease recurrence or progression occurred in 22 cases (15.2%). Of all patients, 125 cases survived, 6 cases died and 14 cases were lost to follow-up. Among the survived cases, 123 cases were continuously at CR state,and the follow-up time was 55 (40, 76) months. The 5-year overall survival (OS) and event free survival (EFS) rates were (95.3±1.9)% and (84.2±3.0)% for the entire group, respectively. 5-year OS and EFS rates for patients with stage Ⅲ-Ⅳ were both lower than those for patients with stage Ⅰ-Ⅱ (χ²=6.28 and 7.58, both P<0.05), the 5-year OS and EFS rates for patients in high-risk group were both lower than those for patients in low-risk and medium-risk group (χ²=10.93, 7.79, both P<0.05). The 5-year OS rates for the patient with early CR and without early CR were 100.0% and (90.9±3.6)% (χ²=5.77, P=0.016). EFS rates for the patient with early CR (68 cases) and without early CR (77 cases) were (93.8±3.0)% and (75.8±5.0)% (χ²=8.78, P=0.003). Conclusions: HL-2013 regimen is significantly effective in the treatment of pediatric HL. However, the patients in high-risk group and those without early CR are prone to disease recurrence or progression. Stage Ⅲ-Ⅳ and without early CR were associated with worse prognosis.

Preoperative detection of biomarkers that can predict postoperative survival of gastric cancer patients has important implications for surgical procedures, postoperative chemoradiotherapy and followup. Using multi-center cancer database and online analysis and verifying by qRT-PCR and Western blotting, we found that Osteomodulin (OMD) was highly expressed in gastric cancer tissues (P =0. 015) and could affect the survival of gastric cancer patients (P < 0. 001) and can be detected preoperatively to evaluate the prognosis of gastric cancer patients. The mRNA expression of OMD was significantly correlated with age (P = 0. 034), Lauren typing (P < 0. 001) and clinical stage (P =0. 001) of gastric cancer patients. It also associated with a variety of immune cells (dendritic cellsresting, eosinophils) and the immune checkpoint regulator ENTPD1 (rho = 0. 634, P < 0. 001) and chemokine CXCL12 (rho = 0. 625, P < 0. 001), which affects the occurrence and development of gastriccancer through the immune microenvironment. Therefore, OMD may become a clinically feasible prognostic biomarker of gastric cancer and a new target for immunotherapy.

Objective: To evaluate the relationship between the brain glucose metabolism and left ventricular function parameters, and to explore the cerebral glucose metabolism reduction regions in patients with ischemic heart disease (IHD). Methods: A total of 110 consecutive IHD patients who underwent gated (99)Tc(m)-sestamibi (MIBI) SPECT/CT myocardial perfusion imaging, gated (18)F-fluorodeoxyglucose (FDG) PET/CT myocardial and brain glucose metabolic imaging within three days in Beijing Anzhen Hospital from April 2016 to October 2017, were enrolled in this study. Left ventricular functional parameters of SPECT/CT and PET/CT including end-diastolic volume (EDV), end-systolic volume (ESV) and left ventricular ejection fraction (LVEF) were analyzed by QGS software. Viable myocardium and myocardial infarction region were determined by 17-segment and 5 score system, and the ratio of viable myocardium and scar myocardium was calculated. According to the range of viable myocardium, the patients were divided into viable myocardium<10% group (n=44), viable myocardium 10%-<20% group (n=36) and viable myocardium≥20% group (n=30). Pearson correlation analysis was used to analyze the correlation between the range of viable myocardium and scar myocardium and the level of cerebral glucose metabolism. Brain glucose metabolism determined by the mean of standardized uptake value (SUV(mean)) was analyzed by SPM. The ratio of SUV(mean) in whole brain and SUV(mean) in cerebellum were calculated, namely taget/background ratio (TBR). Differences in cerebral glucose metabolism among various groups were analyzed by SPM. Results: There were 101 males, and age was (57±10) years in this cohort. The extent of viable myocardium and the extent of scar, LVEF evaluated by SPECT/CT and PET/CT were significantly correlated with TBR (r=0.280, r=-0.329, r=0.188, r=0.215 respectively,all P<0.05). TBR value was significantly lower in viable myocardium<10% group, compared with viable myocardium 10%-<20% group (1.25±0.97 vs. 1.32±0.17, P<0.05) and viable myocardium≥20% group (1.25±0.97 vs. 1.34±0.16, P<0.05). Furthermore, in comparison with viable myocardium≥20% group, the hypo-metabolic regions of viable myocardium<10% group were located in the precuneus, frontal lobe, postcentral gyrus, parietal lobe, temporal lobe, and so on. Conclusions: There is a correlation between impaired left ventricular function and brain glucose metabolism in IHD patients. In IHD patients with low myocardial viability, the level of glucose metabolism in the whole brain is decreased, especially in the brain functional areas related to cognitive function.

A method for simultaneous detection of multi-mycotoxins in ten kinds of common dried fruits was been exploited by using ultra performance liquid chromatography-tandem mass spectrometry. The edible part of dried fruits was ground up with certain quantity of water. The mash was extracted by 10 mmol/L citric acid-acetonitrile, purified by C18 column, and filtered using 0. 22-μm organic filtration. All the sixteen mycotoxins were well separated in 8 min on ACQUITY UPLC BEH C18 column with acetonitrile as phase A and 10 mmol/L ammonium acetate solution containing 0. 1% formic acid as mobile phase B. Result showed that the limits of detection ( LODs) for the sixteen mycotoxins were 0. 01-1. 00 μg/L, with linearity range of 1-200 μg/L and correlation coefficients above 0 . 9981 . The average recoveries of the sixteen mycotoxins in ten matrices were 70. 48% -118. 85%, and the relative standard deviation ( RSD, n=6 ) was 0. 3% -11. 9%. This economical, fast, simple and efficient method could be used for simultaneous detection of multi-mycotoxins in different dried fruits matrixes.
