ABSTRACT

Objective:To investigate the blood pressure change in patients with acute ischemic stroke (AIS) and hypertension treated with cinepazide maleate injection.Methods:This was a subgroup analysis of post-marketing clinical confirmation study of cinepazide maleate injection for acute ischemic stroke: a randomized, double-blinded, multicenter, placebo-parallel controlled trial, which conducted in China from August 2016 to February 2019. Eligible patients fulfilled the inclusive criteria of acute anterior circulation ischemic stroke with National Institutes of Health Stroke Scale (NIHSS) scores of 7-25. The primary endpoints were mean blood pressure of AIS patients treated with cinepazide maleate or control, which were assessed during the treatment period (14 days), and the proportion of the patients with normal blood pressure was analyzed after the treatment period. Furthermore, a subgroup analysis was performed to investigate a possible effect of the history of hypertension on outcomes.Results:This analysis included 809 patients with hypertension. There was no significant difference in patients blood pressure and the proportion of patients with normal blood pressure (60.5% vs. 59.0%, P>0.05) between cinepazide maleate group and control group. Conclusion:Administration of cinepazide maleate injection does not affect the management of clinical blood pressure in patients with AIS.

ABSTRACT

Objective:To explore the association of inflammatory markers and thromboinflammatory factors before and after thrombolytic intervention with functional outcomes in elderly patients with acute cerebral infarction.Methods:392 patients with acute cerebral infarction admitted to our hospital were randomly selected as study subjects and divided into an observation group(196 cases)treated with arterial thrombolytic therapy and a control group(196 cases)treated with intravenous thrombolysis.Functional outcomes of patients were assessed 72 hours after thrombolysis using the activities of daily living(ADL)scale and, based on the results, patients were divided into a poor functional outcome group and a good functional outcome group.Inflammatory markers such as neutrophil-to-lymphocyte ratio(NLR)and platelet-to-lymphocyte ratio(PLR)and thromboinflammatory factors such as monocyte chemoattractant protein-1(MCP-1), tissue plasminogen activator(t-PA), soluble CD40 ligand(sCD40L)and P-selectin before and after thrombolysis were measured.The relationship of these inflammatory markers and thromboinflammatory factors before thrombolysis with functional outcomes 72 hours after thrombolysis was analyzed.Results:NLR and PLR levels in the two groups after thrombolysis were significantly lower than those before thrombolysis(all P<0.05); Their levels in the observation group were lower than those in the control group(all P<0.05). After thrombolysis, MCP-1 levels in both groups were significantly higher and t-PA, sCD40L, P-selectin levels were significantly lower than pre-thrombolysis levels(all P<0.05); After thrombolysis, the observation group had better results than the control group(all P<0.05). Correlation analysis showed that NLR, PLR, MCP-1 and t-PA were positively correlated with NIHSS score( r=0.336, 0.264, 0.483, 0.549, all P<0.05). NLR, PLR, MCP-1, t-PA and sCD40L levels were significantly lower and P-selectin levels were significantly higher in the good functional outcome group than in the poor functional outcome group both before and 72 hours after thrombolysis( t=13.850, 18.208, 23.636, 22.371, 59.868, 96.646, 378.112, 141.213, 131.160, 110.039, 10.716, 11.108, P<0.05 for all). Logistic regression analysis showed that abnormal levels of NLR, PLR, MCP-1 and t-PA before and after thrombolysis were risk factors for adverse outcomes with thrombolytic intervention( P<0.05). ROC curves showed that the levels of NLR, PLR, MCP-1, t-PA, sCD40L and P-selectin before thrombolysis had a certain predictive value for the risk of adverse functional outcomes with thrombolysis. Conclusions:The levels of these inflammatory markers and thromboinflammatory factors before and after thrombolytic intervention have varying degrees of correlation with functional outcomes in elderly patients with acute cerebral infarction.

ABSTRACT

Objective:To confirm the efficacy and safety of cinepazide maleate injection in acute ischemic stroke patients with obvious motor function deficit.Methods:This study is a subgroup analysis of multi-center, randomized, double-blind, placebo-controlled phase Ⅳ clinical trial. A total 812 patients of acute ischemic stroke with obvious limb motor deficit [motor function of limbs score in National Institutes of Health Stroke Scale (NIHSS) ≥4] were enrolled in this subgroup analysis. Patients received either cinepazide maleate injection or placebo. The treatment period was 14 days and follow-up was 90 days. The efficacy endpoints included the proportions of patients with a modified Rankin Scale (mRS) score ≤2, mRS score ≤1 and Barthel Index <95 on day 90. Safety was evaluated by recording all adverse events, monitoring vital signs, laboratory parameters and electrocardiogram.Results:A total of 732 patients were involved in the final efficacy analysis (361 in cinepazide maleate group and 371 in control group). The baseline limb motor function score of NIHSS was 5.23±1.43 in the cinepazide maleate group whereas 5.20±1.36 in the control group. Logistic regression analysis showed that following treatment for 90 days, the proportion of patients with a mRS score ≤2 was significantly higher in the cinepazide maleate group than in the control group [56.0% (202/361) vs 44.2% (164/371), OR=0.60, 95% CI 0.44-0.82, P=0.002]. The proportion of patients with a mRS score ≤1 was higher in the cinepazide maleate group than in the control group [43.3% (139/361) vs 35.2% (118/371), OR=0.69, 95% CI 0.50-0.97, P=0.031]. The proportion of patients with a Barthel Index <95 on day 90 was significantly lower in the cinepazide maleate group than in the control group [45.2% (145/361) vs 55.2% (185/371), OR=0.64, 95% CI 0.46-0.88, P=0.007]. During the treatment and follow-up period, the incidence of the most common adverse events in the cinepazide maleate group was 50.4% (199/395). Constipation and abnormal liver function were more common, but there were no statistically significant differences between the two groups. Conclusion:Cinepazide maleate injection is superior to placebo in improving neurological function and activities of daily living, reducing disability, and promoting functional recovery and safe in patients with acute ischemic stroke with obvious limb motor deficit.

ABSTRACT

Objective:To explore the safety and efficacy of camrelizumab salvage therapy for extrahepatic recurrent hepatocellular carcinoma with PD-L1 negativity in transplanted liver tissue.Methods:From May 2020 to December 2020, retrospective analysis was performed for 3 cases of camrelizumab salvage therapy for extrahepatic recurrent hepatocellular carcinoma recipients with PD-L1 negative in transplanted liver tissue.Three recipients with extrahepatic recurrence progressed after first/second-line targeted drug therapy.Camrelizumab was given as salvage therapy after normal tissue of ransplanted liver was confirmed as negative for PD-L1 by immunohistochemistry.The safety and efficacy of treatment were observed by monitoring the changes in the levels of alanine aminotransferase, aspartate aminotransferase and bilirubin, the occurrence of complications and the outcome of treatment before and after dosing.Results:During a follow-up period of 1.5 to 15.5 months, no recipients showed acute rejection symptoms such as sharp elevations of transaminase and bilirubin.Headache ( n=1), vomiting ( n=1) and fatigue & hypertension ( n=1) became relieved after treatment.As of February 28, 2022, there were one survivor and two deaths.The fatal causes were tumor progression ( n=1) and thoracic aortic rupture due to esophageal perforation ( n=1). The survival time of recipients was (11-15.5) months and the progression-free survival time (4-6) months. Conclusions:For extrahepatic recurrent hepatocellular carcinoma with PD-L1-negative liver transplantation in normal liver tissue, camrelizumab salvage therapy can control tumor progression to a certain extent and prolong the survival time of recipients.

ABSTRACT

Objective:To investigate the correlation between the SUV index (SUV max of the lesion/SUV mean of the liver) in 18F-FDG PET/CT imaging and the invasiveness of early lung adenocarcinoma presenting as ground-glass nodule (GGN). Methods:From January 2012 to March 2020, 167 GGN patients (49 males, 118 females; age: (61.5±9.0) years) with early lung adenocarcinoma who underwent PET/CT imaging in Changzhou First People′s Hospital were retrospectively enrolled. The image parameters including the GGN number, location, type, edge, shape, abnormal bronchus sign, vacuole sign, pleural depression, vessel convergence sign, GGN diameter ( DGGN), solid component diameter ( Dsolid), consolidation to tumor ratio (CTR, Dsolid/ DGGN), CT values (CT value of ground-glass opacity (CT GGO), CT value of lung parenchyma (CT LP), ΔCT GGO-LP (CT GGO-CT LP)) and SUV index were analyzed. Single and multivariate logistic regressions were used to analyze the correlation between SUV index and infiltration. The generalized additive model was used for curve fitting, and the piece-wise regression model was used to further explain the nonlinearity. Results:In 189 GGNs, invasive adenocarcinoma accounted for 85.2% (161/189). Single logistic regression showed that the GGN number, type, shape, edge, abnormal bronchus sign, pleural depression, vessel convergence sign, DGGN, Dsolid, CTR, CT GGO, ΔCT GGO-LP and SUV index were related factors of infiltration (odds ratio ( OR) values: 0.396-224.083, P<0.001 or P<0.05). After fully adjusting for confounding factors, SUV index was significantly correlated with increased risk of invasion ( OR=2.162 (95% CI: 1.191-3.923), P=0.011). Curve fitting showed that the SUV index was non-linearly related to the risk of infiltration, and the risk of infiltration increased significantly only when the SUV index was greater than 0.43 ( OR=3.509 (95% CI: 1.429-8.620), P=0.006). The correlation between SUV index and infiltration had no interaction between age, vacuoles, pleural depression and CTR subgroups (all P>0.05). Conclusions:SUV index is an independent factor related to the invasiveness of early lung adenocarcinoma. The higher the SUV index, the greater the risk of invasion; but the two are not simply linearly correlated.

ABSTRACT

Objective:To evaluate the left ventricular diastolic dyssynchrony (LVDD) and its influencing factors early after acute myocardial infarction (AMI) using phase analysis of SPECT gated myocardial perfusion imaging (GMPI).Methods:Bama miniature swines ( n=16) were subjected to establish AMI models. GMPI was performed before and 1 d after AMI to obtain the extent of myocardial perfusion defect (Extent, %) and left ventricular systolic dyssynchrony (LVSD)/LVDD parameters, namely the phase histogram bandwidth (PBW) and phase standard deviation (PSD). Meanwhile, left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), left ventricular ejection fraction (LVEF), and the ratio of early to late peak mitral diastolic flow (E/A) were obtained by echocardiography. Independent-sample t test, paired t test and Pearson correlation analysis were used to analyze the data. Results:Sixteen AMI swines were successfully created. Compared to baseline, Extent, LVEDV and LVESV significantly increased on 1 d after AMI ( t values: -11.14, -4.55, -6.12, all P<0.001), while LVEF and E/A significantly decreased ( t values: 10.16, 2.18, P<0.001, P=0.046). GMPI showed that the LVDD parameters PBW and PSD increased significantly on 1 d after AMI when compared to those at baseline((142.25±72.06)° vs (33.06±8.98)°, (56.15±26.71)° vs (12.51±5.13)°; t values: -6.11, -6.60, both P<0.001). There were significant differences between LVSD parameters and LVDD parameters (PBW: (109.06±62.40)° vs (142.25±72.06)°, PSD: (44.40±25.61)° vs (56.15±26.71)°; t values: -2.73, -2.20, P values: 0.016, 0.044). LVDD parameters PBW, PSD were negatively correlated with E/A after AMI ( r values: -0.569, -0.566, P values: 0.021, 0.022), and positively correlated with the Extent ( r values: 0.717, 0.634, P values: 0.002, 0.008). The phase analysis of SPECT GMPI to evaluate LVDD showed good intra-observer and inter-observe reproducibility (intraclass correlation coefficient (ICC): 0.953-0.984, all P<0.001). Conclusions:LVDD occurs early on 1 d after AMI, and can reflect left ventricular diastolic dysfunction. The Extent is correlated with LVDD significantly. Phase analysis of SPECT GMPI is an accurate method to evaluate LVDD and left ventricular diastolic function.

ABSTRACT

Objective:To investigate the relationship between the volume ratio of ischemic leukoaraiosis (LA) and cognitive level and arterial perfusion.Methods:Fifty-four patients, who was hospitalized in Dalian Central Hospital and diagnosed as LA clinically during the time of March to December in 2012, were selected to collect the information of the volume ratio of white matter disease, MoCa score and the average flow rate of carotid artery. The correlation between the volume ratio of white matter disease and MoCa score, cognitive impairment and the average flow rate of carotid artery were analyzed.Results:The volume ratio of LA lesions was negatively correlated with MOCA score ( r = -0.59, P<0.01); the volume ratio of LA lesions was negatively correlated with the mean flow rate of internal carotid artery ( r = -0.37, P<0.01). Quantity order of the area under receiver operating characteristic (ROC) curve of MoCA cognitive subgroup was as following: delayed memory (1.000)> visual space/executive function (0.970) = abstract force (0.970)> language ability (0.960)> attention (0.888). Conclusions:The larger the volume ratio of leukopathy in LA patients, the more serious the cognitive impairment, especially the cognitive impairment of impairment of memory delay, visual space/executive function, abstract ability and language ability.

ABSTRACT

Objective:To express virus-like particles of poliovirus type 2 (PV2-VLP) in insect cells using a recombinant baculovirus expressing P1 and 3CD and to preliminarily evaluate its immunogenicity.Methods:Based on the codon preference of High 5 cells, the sequences of P1 gene and 3CD gene of PV2 were optimized and inserted into pUC57-Amp to construct pUC57-PV2-P1 and pUC57-PV2-3CD. UC57-PV2-P1s mutant that carried P1 gene mutation affecting thermostability was then constructed. Recombinant baculovirus strains of rBac-PV2-P1s-3CD and rBac-PV2-P1-3CD (wild type) were constructed using homologous recombination. The expression of target proteins was detected by Western blot. PV2-VLP was purified by ion exchange chromatography. The structure of VLP was observed under transmission electron microscopy to evaluate the assembly efficiency. The immunogenicity of PV2-VLP was assessed in a rat model.Results:The recombinant baculovirus with stable expression of P1s and 3CD proteins was successfully constructed. Western blot results showed that the yield of VLP was higher after thermostability mutation than that of the wild type. A three-dimensional structure with a diameter of about 30 nm was observed under electron microscopy, indicating that the VLP was successfully assembled. Animal experiment showed that the recombinant PV2-VLP had immunogenicity and could effectively induce the production of neutralizing antibodies.Conclusions:Effective VLP vaccines could be successfully prepared using the insect cell-baculovirus expression system, which provided reference for the development of polio VLP vaccine.

ABSTRACT

Objective:To analyze the relationship between red cell distribution width (RDW) and disease severity in patients with non-ST-elevation myocardial infarction.Methods:Seventy patients with non-ST-elevation myocardial infarction who received treatment in Chaozhou People's Hospital from June 2019 to June 2020 were included in the observation group. An additional 70 patients with ST-elevation myocardial infarction who concurrently received treatment in the same hospital were included in the control group. All patients underwent electrocardiography and blood biochemical index examination. RDW was compared between the observation and control groups. The relationship between RDW and the severity of non-ST-elevation myocardial infarction was analyzed.Results:RDW in the observation group was significantly higher than that in the control group [(14.60 ± 1.00) % vs. (13.06 ± 1.70) %, t = 5.884, P = 0.012). The detection rate of coronary artery thrombosis in the observation group was significantly higher than that in the control group [70.00% (49/70) vs. 50.00% (35/70), χ2 = 7.563, P = 0.002]. In the observation group, the area under the receiver operating characteristic (ROC) curve plotted taking RDW as the variable was 0.649 (95% CI 0.546-0.753, P = 0.006). When the critical value of RDW was 14%, the sensitivity and specificity of RDW in the prediction of non-ST-elevation myocardial infarction were 73% and 59% respectively. RDW was positively correlated with cardiac troponin I level ( r = 0.19, P = 0.006). Conclusion:In patients with non-ST-elevation myocardial infarction, the increase in RDW is related to myocardial injury and the increase in cardiac troponin I level. RDW can be used as an effective index to predict the severity of non-ST-elevation myocardial infarction.

ABSTRACT

Objective:To investigate the predictive value of 18F-fluorodeoxyglucose (FDG) PET/CT metabolic parameters for occult lymph node metastasis (OLM) in non-small cell lung cancer (NSCLC). Methods:A total of 183 patients (72 males, 111 females; age (61.5±8.4) years) who underwent 18F-FDG PET/CT and preoperatively diagnosed with clinical N0 stage (cN0) in Third Affiliated Hospital of Soochow University from January 2013 to December 2018 were retrospectively enrolled. All patients underwent anatomical pulmonary resection with systematic lymph node dissections within 3 weeks after 18F-FDG PET/CT examinations. According to the presence or absence of lymph node metastasis, patients were divided into OLM positive (OLM+ ) group and OLM negative (OLM-) group. Parameters of primary lesions, such as the maximum diameter (D max), tumor sites, morphological features, maximum standardized uptake value (SUV max), mean standardized uptake value (SUV mean), metabolic total volume (MTV), total lesion glycolysis (TLG), tumor SUV max to liver SUV mean (TLR max), tumor TLG to liver SUV mean (TLR TLG) were analyzed. Mann-Whitney U test and χ2 test were used to compare the parameters between groups. Multivariable logistic regression was used to analyze the independent risk factors for OLM. Receiver operating characteristic (ROC) curve analysis was used to evaluate the diagnostic value of different parameters. Results:Among 183 patients, 25 (13.7%, 25/183) of them were diagnosed as OLM. In OLM+ group, 46 lymph nodes were pathologically positive for metastasis, including 15 N1 disease and 31 N2 disease. D max (2.9(2.3, 3.7) vs 2.3(1.7, 2.8) cm), lobulation ((76.0%(19/25) vs 37.3%(59/158)), SUV max (11.1(7.9, 17.7) vs 4.7(2.3, 9.2)), TLG (41.5(10.2, 91.1) vs 15.6(6.5, 23.8) ml), TLR max (4.7(3.5, 7.6) vs 2.1(0.9, 4.0)) and TLR TLG (18.1(5.0, 44.3) vs 6.1(3.0, 11.4) ml) of the primary lesions in OLM+ group were significantly higher than those in OLM-group ( z values: from -4.709 to -3.247, χ2=13.190, all P<0.05). Multivariable logistic regression analysis showed that TLR max (odds ratio ( OR)=15.145, 95% CI: 3.381-67.830, P<0.001) and D max ( OR=3.220, 95% CI: 1.192-8.701, P=0.021) were independent risk factors for OLM. TLR max yielded the highest area under curve (AUC; AUC=0.794) with the threshold of 3.12, and the sensitivity, specificity, accuracy, positive predictive value and negative predictive value for predicting OLM were 92.0%(23/25), 63.3%(100/158), 67.2%(123/183), 28.4%(23/81) and 98.0%(100/102), respectively. Conclusions:TLR max of tumor is the independent risk factor for OLM in NSCLC patients. TLR max can sensitively predict OLM preoperatively in patients with NSCLC.

ABSTRACT

Objective To evaluate the effect of microvascular invasion (MVI) on prognosis of recipients after liver transplantation for primary liver cancer (liver cancer). Methods Clinical data of 177 recipients after liver transplantation for liver cancer were retrospectively analyzed. All patients were divided into the MVI-positive group (n=64) and MVI-negative group (n=113) according to postoperative pathological examination results. Clinical data were statistically compared of all recipients between the negative and positive MVI groups. The prognosis and risk factors of liver transplantation recipients for liver cancer were analyzed. Results Among 177 recipients, 64 cases (36.2%) were positive for MVI and 113 (63.8%) negative for MVI. Compared with the MVI-negative recipients, MVI-positive recipients had significantly lower degree of tumor differentiation, higher preoperative alpha-fetaprotein (AFP) level, larger maximal tumor diameter, a larger quantity of tumors, more satellite lesions and more recipients who did not meet the Milan criteria (all P < 0.05). The 1-, 3- and 5-year overall survival (OS) and recurrence-free survival (RFS) of recipients after liver transplantation for liver cancer were 80.2%, 62.1%, 58.5% and 66.3%, 57.5%, 51.2%, respectively. The 1-, 3- and 5-year OS and RFS of MVI-positive recipients were 70%, 39%, 35% and 53%, 39%, 33%, significantly lower than 86%, 75%, 72% and 73%, 68%, 63% of their counterparts negative for MVI (all P < 0.05). Cox regression analysis showed that the maximal tumor diameter >8 cm, preoperative AFP level ≥20 ng/mL, low degree of tumor differentiation and positive MVI were the independent risk factors for OS of recipients after liver transplantation for liver cancer (all P < 0.05). Positive MVI, low degree of tumor differentiation and preoperative down-staging failure were the independent risk factors for RFS of recipients after liver transplantation for liver cancer (all P < 0.05). Conclusions MVI is of significant clinical value in predicting clinical prognosis of recipients after liver transplantation for liver cancer.

ABSTRACT

Objective:To develop a new method based on neuraminidase (NA) activity for detec-ting virus titers of cell culture-based influenza vaccines and preliminarily analyze its application.Methods:Reaction conditions including the substrate concentration for enzymatic reaction, stop solution, the number of initially infected target cells and cell lysis buffer were optimized. The titers of cell culture-based influenza vaccine strains were detected by the established method and the results were compared with those by the traditional viral titration test.Results:The optimal substrate concentration for enzymatic reaction was 25 μmol/L, and the optimal stop solution was 0.2 mol/L Na 2CO 3. In the detection of NA activity in infected cells, the maximum relative fluorescence value was obtained by infecting 4×10 4 cells/well with influenza virus for 48 h and using 0.5% TritonX-100 for lysis. The developed method showed no significant differences with the traditional virus titration test in detecting the titers of four batches of influenza vaccine virus strains ( P>0.05), indicating that the two methods had a good consistency. Conclusions:This study established a new method based on NA activity to detect virus titers of cell culture-based influenza vaccines. The method could be used for the detection of virus strains used in the production of cell cultured-based influenza vaccines.

ABSTRACT

Objective:To assess the efficacy and safety of cinepazide maleate injection in the treatment of patients with acute ischemic stroke.Methods:A multicenter, randomized, double-blind, placebo-controlled phase Ⅳ clinical trial, led by Peking Union Medical College Hospital, was conducted in 65 Hospitals in China. The efficacy of cinepazide maleate injection in patients with acute anterior circulation cerebral infarction with onset time of ≤48 hours, 7≤National Institute of Health stroke scale (NIHSS) score ≤25 was assessed from August 2016 to February 2019, using the proportion of modified Rankin scale (mRS) score≤1 and Barthel index (BI) score≤95 on day 14 as efficacy endpoint. The patients were divided into treatment group who were treated with cinepazide maleate injection and control group who were treated with placebo.Results:A total 937 patients were involved in the final efficacy analysis (466 in treatment group and 471 in control group). The proportion of subjects with mRS score≤1 on day 14 after treatment were higher in the treatment group than that in the control group (102/466(21.89%) vs76/471(16.14%)). Logistic regression analysis showed that patients treated with cinepazide maleate were significantly more likely to have a favorable outcome (mRS score≤1) than patients treated with placebo on day 14 ( OR=0.677, 95% CI 0.484-0.948 , P=0.023), and patients treated with cinepazide maleate were more likely to reach independence in activities of daily living (Barthel Index ≥95) than those treated with placebo on day 14 (125/466(26.82%) vs 91/471(19.32%); OR=0.632, 95% CI0.459-0.869, P=0.005). The rate of adverse events was similar between the treatment and control groups. Conclusion:The 14-day treatment with cinepazide maleate injection could reduce the degree of disability whereas did not increase the risk of adverse events.

ABSTRACT

Objective:To evaluate the value of standardized uptake value of the left ventricle (SUV LV) during 18F-fluorodeoxyglucose (FDG) PET/CT imaging in the detection of the cardiotoxicity of anthracycline in non-Hodgkin lymphoma (NHL). Methods:Twenty-two patients(13 males and 9 females, age: ( 58±13 ) years) diagnosed as NHL from January 2016 to June 2019 were retrospectively enrolled in the study. All patients received chemotherapy regimens containing anthracycline. The gated myocardial perfusion imaging (GMPI) and whole body 18F-FDG PET/CT imaging were performed before and after chemotherapy in Changzhou First People′s Hospital. The significant reduction of diastolic function after chemotherapy measured by GMPI was defined as anthracycline induced myocardial injury. The SUV LV before and after chemotherapy and the changes (ΔSUV LV ) in patients with or without myocardial injury were compared with independent-sample t test or paired t test. The receiver operating characteristic (ROC) curve analysis was used to determine whether SUV LV could be used to detect anthracycline induced myocardial injury. Results:The reduction of LVEF after chemotherapy was more significant in myocardial injury group ( n=6) than that in patients without myocardial injury ( n=16; ΔLVEF: (-5.8±7.5)% vs (2.7±3.8)%, t=2.657, P<0.05). After chemotherapy, an increase was found in SUV LV of patients with myocardial injury (maximum SUV LV (SUV LVmax): 7.5±4.4 vs 2.6±1.0, t=2.585, P<0.05; mean SUV LV (SUV LVmean): 3.7±2.2 vs 1.6±0.8, t=2.119, P>0.05), but no differences were found in SUV LV of patients without myocardial injury (SUV LVmax: 5.7±4.9 vs 5.6±4.8, SUV LVmean : 2.8±2.3 vs 2.8±2.2; t values: 0.130, 0.069, both P>0.05). Compared with patients without myocardial injury, patients with myocardial injury had higher ΔSUV LV ( t values: 2.494, 2.163, both P<0.05) and lower pre-chemotherapy SUV LVmax ( t=2.436, P<0.05). ROC curve analysis showed that ΔSUV LVmax and ΔSUV LVmean could be used for the detection of chemotherapy induced cardiotoxicity, and higher area under curve (AUC) of ΔSUV LVmaxwas found (AUC=0.844, 95% CI: 0.673-1.000). When the threshold value was 1.1, the sensitivity and specificity of ΔSUV LVmax in the detection of myocardial injury were 5/6 and 13/16, respectively. Conclusions:Higher ΔSUV LVmax and ΔSUV LVmean, as well as lower baseline SUV LVmax are correlated with cardiotoxicity of anthracycline. ΔSUV LVmax has a potential for the diagnosis of anthracycline induced cardiotoxicity in patients with NHL.

ABSTRACT

Objective:To explore the value of 18F-deoxyglucose (FDG) PET and high resolution CT (HRCT) combined prediction model in the identification of invasiveness of early lung adenocarcinoma with consolidation-to-tumor ratio (CTR)≤0.5. Methods:A retrospective analysis was performed on 91 patients with early lung adenocarcinoma with CTR≤0.5 who underwent PET/CT and HRCT before surgery in the Third Affiliated Hospital of Soochow University from October 2011 to October 2019, including 110 ground-glass nodules (GGNs). According to the pathological subtypes, they were divided into preinvasive-minimally invasive adenocarcinoma (MIA) group ( n=22) and invasive adenocarcinoma (IAC) group ( n=88). The image feature parameters of GGNs of the two groups were compared, and the HRCT model and PET-HRCT combined model were constructed using Logistic regression analysis. Receiver operating characteristic (ROC) curve analysis was used to compare the diagnostic efficacy of different models. The Bootstrap resampling (times = 500) method was used for internal verification of the model, and we also performed interaction and hierarchical analysis on the model. Results:The proportions of mixed GGN, irregular shape, lobulation sign, dilated/distorted/cutoff bronchial sign, pleural indentation and vascular convergence in IAC group were significantly higher than those in preinvasive-MIA group (all P<0.05). Nodule diameter, solid component diameter, solid component ratio, CT value of ground glass attenuation component (CT GGO), and SUVindex of the IAC group were larger than those of the preinvasive-MIA group, and the differences were statistically significant ( P<0.001). Among the quantitative parameters of HRCT, CT GGO had the best diagnostic efficacy (AUC=0.775), with a sensitivity of 0.580 and a specificity of 0.909. The diagnostic efficacy of HRCT model and PET-HRCT combined model were better than CT GGO (AUC: 0.907 vs. 0.775, 0.931 vs. 0.775; P=0.027, 0.002, respectively), but the diagnostic efficacy of the former two was not statistically different ( P=0.210).When the specificity was 0.909, the sensitivity of the HRCT model and the PET-HRCT model (0.784 and 0.875, respectively) were significantly higher than that of the CT GGO (0.580), and the combined PET-HRCT model had a more significant increase in sensitivity. The PET-HRCT combined model showed no significant interaction between different nodule types, between groups with or without pleural indentation, and among nodule diameter subgroups (all P>0.05). Conclusion:PET-HRCT combined model has a good predictive value for the invasiveness of early lung adenocarcinoma with CTR≤0.5, and it can be used for GGN risk stratification to guide clinical decision-making.

ABSTRACT

Objective:To evaluate the safety and efficacy of balloon pulmonary angioplasty (BPA) in the treatment of chronic thromboembolic pulmonary hypertension (CTEPH).Methods:A study was conducted on 25 patients consisting of 10 males and 15 females with CTEPH who received BPA treatment from February 2017 to May 2018 in Beijing Chaoyang Hospital, Capital Medical University. The changes of brain natriuretic peptide (BNP), mean pulmonary artery pressure (mPAP), tricuspid annulus systolic plane excursion (TAPSE), six-minute walking test (6WMD), right ventricular basement diameter and WHO cardiac function grading were compared before and after treatment with BPA using paired t test. Results:Twenty-five patients received a total of 50 BPA treatments, and among them, 12 patients received two or more times. The mPAP decreased from (50.4±9.9) mmHg (1 mmHg=0.133 kPa) to (39.9±10.6) mmHg before and after operation, and the difference was statistically significant ( t=9.7, P<0.001); BNP decreased from (513.5±357.3) pg/ml to (106.3±137.53) pg/ml, and the difference was significant ( t=3.2, P=0.006); TAPSE increased from (16.2±2.8) mm to (18.0±2.4) mm, and the difference was statistically significant ( t=-5.7, P=0.002); the right ventricular base diameter decreased from (45.9±6.9) mm to (41.2±7.3) mm, and the difference was statistically significant ( t=5.6, P<0.001); 6WMD increased from (371.1±86.8) m to (467.7±76.1) m, with statistical significance ( t=-6.4, P<0.001); WHO cardiac function grading was improved from (2.4±0.7) to (1.2±0.4) after surgery, and the difference was statistically significant ( t=2.8, P=0.021). Pulmonary artery injury occurred in 3 patients and 2 patients had hemoptysis.The hemoptysis was stopped after arterial embolization. No other complications such as pulmonary edema occurred. Conclusion:BPA may improve clinical status and hemodynamics of patients with CTEPH, which offers an alternative approach of treatment in patients with inoperable CTEPH.

ABSTRACT

Objective:To compare the efficacy of flexible ureteroscopic lithotripsy (FURL) and NTrap ureteroscopic lithotripsy (NTrapURL) in the treatment of upper ureteral calculi.Methods:A retrospective analysis of the case data of 243 patients undergoing unilateral upper ureteral calculi lithotripsy admitted to the First Hospital of China Medical University from January 2012 to March 2018 were divided into two groups according to different treatment methods: FURL group ( n=74) and NTrapURL group ( n=169). Patients in the FURL group were treated with FURL, and patients in the NTrapURL group were treated with NTrapURL. Operation time, intraoperative stone moving up, postoperative meaningless residual stone, postoperative hospitalstay, stone-free rate, short-term complications (including pain, hematuria, fever) and long-term complications (including ureteral stenosis) were recorded, two surgical methods were analyzed. The measurement data conforming to the normal distribution were expressed as mean±standard deviation ( Mean± SD), and the independent sample t-test was used for comparison between groups; the measurement data of non-normal distribution were expressed as the median (interquartile range) [ M( P25, P75)] means that the non-parametric rank sum test of independent samples was used for comparison between groups; the Chi-square test or Fisher exact probability method was used for the comparison of count data between groups, and the nonparametric rank sum test of ordinal variables was used for grade data. Results:There was not statistically significant difference between the operation time of patients in the FURL group and the NTrapURL group [(31.08±13.29) min vs (33.49±12.10) min]( P=0.582). There was no difference in short-term complications (pain: 43.24% vs 50.30%, fever: 1.35% vs 3.55%, hematuria: 31.08% vs 23.67%) and long-term complications (0 vs 3.55%) in the FURL group and NTrapURL group, there was not statistically significant difference ( P>0.05); the postoperative hospital stay of patients in the FURL group and NTrapURL group [(2.34±0.96) d vs (2.21±0.88) d], the difference was not statistically significant ( P>0.05); The intraoperative stone movement rate of FURL group was significantly higher than that of the NTrapURL group (87.84% vs 18.93%), and the difference was statistically significant ( P<0.001); the first stone clearance rate of the FURL group was higher than that of the NTrapURL group (94.59% vs 81.07%), the difference was statistically significant ( P=0.006); the postoperative insignificant residual stone rate in the FURL group was significantly higher than that in the NTrapURL group (31.08% vs 18.34%), and the difference was statistically significant ( P=0.043). Conclusion:FURL and NTrapURL are safe and effective in the treatment of upper ureteral calculi, but FURL has a higher stone-free in the treatment of upper ureteral calculi.
