ABSTRACT

Objective:To evaluate the kinetic metrics changes of FDG in key organs after chemo-immunotherapy in patients with locally advanced non-small cell lung cancer (NSCLC) identified by total-body PET/CT dynamic imaging, and explore its potential biological significance.Methods:From August 2020 to March 2021, 16 patients (13 males, 3 females; age: 43-67 years) with locally advanced NSCLC who underwent total-body 18F-FDG PET/CT dynamic imaging in Sun Yat-sen University Cancer Center were retrospectively analyzed. ROIs of key organs were drawn at baseline and after chemo-immunotherapy to obtain the time-activity curves (TACs). The kinetic metrics, including K1, k2, k3 and metabolic rate of FDG (MR FDG), were fitted by the two-tissue compartment model. Paired t test or Wilcoxon signed rank test was used to compare the differences of FDG kinetic parameters in each organ before and after treatment. Results:Compared with baseline, SUV max of colon (3.23±1.29 vs 4.81±2.73), MR FDG ((2.77±1.96) vs 3.56(1.07, 9.89) μmol·100 g -1·min -1) of lungs, SUV max (2.16±0.27 vs 2.33±0.41), k3 ((0.008±0.002) vs (0.012±0.004) min -1) and MR FDG ((2.65±0.81) vs (3.76±1.59) μmol·100 g -1·min -1) of spleen, and SUV max (2.59±0.45 vs 4.49±2.73), k2 ((0.76±0.37) vs (1.27±0.66) min -1), k3 ((0.032±0.007) vs (0.066±0.029) min -1) and MR FDG ((5.14±1.44) vs (8.39±2.67) μmol·100 g -1·min -1) of bone marrow were increased after chemo-immunotherapy with significant differences ( t values: from -5.40 to 3.47, z=-2.02, all P<0.05). There were no significant differences of SUV max, k values and MR FDG in other organs ( t values: from -2.00 to 2.35, z values: from -1.45 to -0.05, all P>0.05). Conclusions:After chemo-immunotherapy, the activation of immune system may be manifested as the increase of FDG kinetic rate constants in spleen and bone marrow. The lung and colon may be target organs for immune-related adverse effects.

ABSTRACT

Objective:To investigate the relationship between triglyceride-glucose(TyG) index and vascular cognitive impairment(VCI) in elderly patients with cerebral small vessel disease (CSVD).Methods:A total of 275 patients with CSVD aged 60 years or above admitted in the Department of Neurology of the Second Affiliated Hospital of Nantong University from August 2019 to March 2021 were enrolled in this retrospective study. According to the cognitive function assessed with Montreal Cognitive Assessment (MoCA), patients were divided into VCI group (187 cases) and non-VCI group (88 cases). Receiver operating characteristic (ROC) curve analysis was conducted to assess the value of TyG index in predicting VCI. Binary logistic regression analysis was employed to analyze the correlation between TyG index and VCI.Results:TyG index was higher in the VCI group than that in non-VCI group (9.07±0.54 vs. 8.70±0.55, t = 5.24, P<0.01). The area of ROC curve (AUC) of TyG index for predicting VCI was 0.70 (95% CI:0.64-0.77, P<0.01); taking 8.78 as the optimal cut-off point, the sensitivity and specificity were 0.754 (141/187) and 0.614(54/88), respectively. The proportion of VCI patients in high TyG index group (≥8.78) was higher than that in low TyG index group (<8.78) [141 (80.6%) vs. 46 (46.0%), χ2=34.95, P<0.01]. The binary logistic regression analysis showed that after adjusting for age, level of education, low-density lipoprotein cholesterol (LDL-C), homocysteine (Hcy), uric acid (UA) and total CSVD burden, TyG index was an independent risk factor of VCI ( OR=2.42, 95% CI: 1.37-4.29, P<0.01); and compared to patients with low TyG index (<8.78) the risk of VCI was increased for patients with high TyG index (≥8.78) ( OR=4.09, 95% CI: 2.18-7.68, P<0.01). Conclusion:TyG index is associated with VCI in elderly patients with CSVD, which may be used as a predictor of VCI for those patients.

ABSTRACT

BACKGROUND@#The detection of pulmonary nodules is a key step to achieving the early diagnosis and therapy of lung cancer. Deep learning based Artificial intelligence (AI) presents as the state of the art in the area of nodule detection, however, a validation with clinical data is necessary for further application. Therefore, the aim of this study is to evaluate the performance of AI in the detection of malignant and non-calcified nodules in chest CT.@*METHODS@#Two hundred chest computed tomography (CT) data were randomly selected from a self-built nodule database from Tianjin Medical University General Hospital. Both the pathology confirmed lung cancers and the nodules in the process of follow-up were included. All CTs were processed by AI and the results were compared with that of radiologists retrieved from the original medical reports. The ground truths were further determined by two experienced radiologists. The size and characteristics of the nodules were evaluated as well. The sensitivity and false positive rate were used to evaluate the effectiveness of AI and radiologists in detecting nodules. The McNemar test was used to determine whether there was a significant difference.@*RESULTS@#A total of 889 non-calcified nodules were determined by experts on chest CT, including 133 lung cancers. Of them, 442 nodules were less than 5 mm. The cancer detection rates of AI and radiologists are 100%. The sensitivity of AI on nodule detection was significantly higher than that of radiologists (99.1% vs 43%, P<0.001). The false-positive rate of AI was 4.9 per CT and decreased to 1.5 when nodules less than 5 mm were excluded.@*CONCLUSIONS@#AI achieves the detection of all malignancies and improve the sensitivity of pulmonary nodules detection beyond radiologists, with a low false positive rate after excluding small nodules.

ABSTRACT

BACKGROUND@#Subsolid pulmonary nodules are common computed tomography (CT) findings of primary lung adenocarcinoma. It is of clinical value to determine the clinical treatment strategies based on CT features. The aim of this study is to find the valuable CT characteristics on differential diagnosis and the degree of invasion prediction by a retrospectively analysis of three groups subsolid nodules, including benign, and invasive adenocarcinoma.@*METHODS@#The CT findings of 106 cases of resected sub-solid nodules were retrospectively analyzed. The nodules were firstly divided into benign and malignant groups and the malignant group was further divided into non/micro-invasive group (atypical adenomatous hyperplasia/adenocarcinoma in situ/minimally invasive adenocarcinoma) and invasive adenocarcinoma group. The nodule size, proportion of solid components, tumor-lung interface, shape, margin, pleural traction, air bronchus sign, vascular abnormalities inside the nodule were evaluated. The univariate analysis (χ2 test, non-parametric test Mann-Whitney U test) was performed to screen statistically significant variables and then enrolled in further multivariate Logistic regression analysis.@*RESULTS@#Multivariate logistic regression analysis showed that a clear tumor-lung interface, air bronchus sign, and pulmonary vascular abnormalities were important indicators of malignant nodules with hazard ratios of 38.1 (95%CI: 5.0-287.7; P<0.01), 7.9 (95%CI: 1.3-49.3; P=0.03), 7.2 (95%CI: 1.4-37.0; P=0.02), respectively. The proportion of solid components was the only significant indicator for identifying invasive adenocarcinoma from AAH/AIS/MIA , with a risk ratio of 1.04 (95%CI: 1.01-1.06, P=0.01).@*CONCLUSIONS@#SSNs with clear tumor-lung interface, air bronchus sign, and pulmonary vascular abnormality inside nodule are more likely to be malignant. A higher percentage of solid components indicates a higher likelihood to be an invasive lesion in malignant SPNs.

ABSTRACT

Objective To investigate the positive rate of microembolic signal (MES) and the related factors,as well as the correlation between MES and outcomes in patients with cardiogenic cerebral embolism.Methods Patients with cardiogenic cerebral embolism were enrolled.The baseline data of the patients were collected and the MES monitor was conducted.The baseline data of the MES positive group and MES negative group were compared.Multivariatelogistic regression analysis was used to identify the related factors of the positive MES.The patients were followed up regularly.The outcomes of stroke at 6 months and recurrent stroke within 2 years in the MES positive group and MES negative group were compared.Results A total of 165 patients with cardiogenic cerebral embolism were enrolled,including positive MES in 68 patients (41.2%).There were significant difference in the levels of brain natriuretic peptide (BNP),cardiac troponin-I (cTn-I),and D-dimer between the MES positive group and negative group.Multivariate logistic regression analysis showed that the increased levels of baseline BNP (odds ratio [OR] 1.001,95% confidence interval CI 1.001-1.002;P<0.001),cTn-I (OR 36.975,95% CI 1.516-902.0;P=0.027),and D-dimer (OR 1.001,95% CI 1.000-1.001;P=0.017) were independently associated with the positive MES in cerebral embolism within 48 h after onset.There was no significant difference in the proportion of patients in good outcome (modified Rankin scale score 0-2) and poor outcome (modified Rankin scale score >2) after 6 months between the MES positive group and MES negative group.When the average follow-up time was 20.8 months (range,7-24 months),there were 23 patients (33.8%) and 19 (19.6%) had recurrence in the MES positive group and MES negative group,respectively.Kaplan-Meier analysis showed that the recurrence rate of stroke in the MES positive group was significantly higher than that in the MES negative group (log-rank test:P=0.031).COX regression analysis showed that the positive MES was still an independent risk factor for stroke recurrence after adjusting for other confounding factors (OR 0.328,95% CI 0.142-0.761;P=0.009).Conclusions The positive MES was associated with the increased BNP,cTn-I,and D-dimer levds.The positive MES was not associated with clinical outcomes at 6 month after the onset,but it was associated with the recurrence of stroke within 2 years.

ABSTRACT

Objective Renal ischemia-reperfusion may cause myocardial injury and dexmedetomidine ( DEX)is a new alpha-2 adrenergic agonist which has the effects of antisympathia , sedation and analgesia.The article was to observe the effects of different doses of dexmedetomidine on myocardial injury induced by renal ischemia -reperfusion(I/R) in Rats. Methods 40 male Wistar rats were randomized into 5 groups(n=8 each)using a random number table: sham operation group(isolation of bilateral renal pedicles without ligation), I/R group (3 hours′reperfusion 120 minutes after the right nephrectomy and the ligation of left renal artery ), DEX low dose group, DEX middle dose group and DEX high dose group (DEX 25, 50, 100 μg/kg were respectively injected intraperitone-ally in rats of the three groups plus 3 hours′reperfusion after 120 minutes′ischemia ) .Blood samples were collected at 3 hours′reper-fusion to determine serum creatinine(Cr) and blood urea nitrogen(BUN) concentrations.Kidney and myocardial specimens were ex-tracted for microscopic examination and IL-10,TNF-αcontent were detected by ELISA. Results In sham operation group, renal structure was normal.In I/R group, a great amount of erythrocyte infiltration and interstitial infiltrating inflammatory cells were found in glomerulus and a lot of exfoliative cells were found in renal tubules .In DEX low dose group , erythrocyte infiltration and interstitial infiltrating inflammatory cells were found in glomerulus and a few exfoliative cells were found in renal tubules .In DEX middle dose group, erythrocyte infiltration and interstitial infiltrating inflammatory cells were found in partial glomerulus and a few exfoliative cells were found in renal tubules .In DEX high dose group , erythrocyte infiltration and interstitial infiltrating inflammatory cells in partial glomerulus were found and rare exfoliative cells were found in renal tubules .In sham operation group , cardiomyocytes were arranged in perfect order and normal structure , and chromatins and cytoplasms were in uniform distribution .In I/R group, edema and spongiform were obvious in cardiomyocytes , and focal coagulative necrosis was observed along with a great amount of infiltrating inflammatory cells and rare flaky bleeding .In DEX low dose group , edema and spongiform were found in cardiomyocytes , and focal coagulative necrosis was observed along with a great amount of infiltrating inflammatory cells and rare flaky bleeding .In DEX middle dose group , edema was found in cardiomyocytes , and mini focal coagulative necrosis was observed along with a small amount of infiltrating inflammatory cells.In DEX high dose group , edema was found in cardiomyocytes along with a small amount of infiltrating inflammatory cells .Com-pared with sham operation group , Cr, BUN concentrations in serum and IL-10,TNF-αcontents in kidney tissue and myocardium signif-icantly increased in I/R group, low dose group, middle dose group and high dose group(P<0.05).Compared with I/R group, IL-10 contents kidney tissue and myocardium significantly increased in small dose group (P<0.05).Cr ([167.11 ±18.81, 135.46 ± 9.80, 114.29 ±12.50, 100.15 ±8.81]μmol/L), BUN ([13.42 ±1.25, 11.73 ±1.15, 10.27 ±0.78, 9.28 ±0.52] mmol/L) concentrations in serum and TNF-αcontents in kidney tissue ([578.45 ±30.59, 530.76 ±20.59, 482.23 ±27.12, 423.14 ± 21.16]ng/L) and myocardium ([565.00 ±37.66, 517.82 ±36.89, 469.99 ±32.43, 407.41 ±23.77] ng/L) significantly de-creased in a dose-dependent manner in low , middle and high groups (P<0.05).Microscopic examination showed that the pathological changes of both kidney tissue and myocardium were significantly attenuated in low , middle and high dose group . Conclusion Dexmedetomidine can allenuate myocardial tissue injury induced by renal ischemia -reperfusion in a dose-dependent manner in rats and its mechanism may be involved with the inhibition of inflammatory factors .

ABSTRACT

Objectiv e Renal ischemia-reperfusion ( I/R) may cause myocardial injury and dexmedetomidine ( DEX) is a new alpha-2 adrenergic agonist with the effects of antisympathia , seda-tion, and analgesia.This study was to investigate the effect of DEX on the myocardial tissue of rats at different time points after renal I/R. Methods Forty male Wistar rats were randomized into 5 groups of equal number,sham operation, 60 min renal ischemia and 3 h reperfusion (I/R1), 120 min ischemia and 3 h reperfusion (I/R2 ), 60 min ischemia and DEX+3 h reperfusion (D1), 120 min ischemia and DEX+3 h reperfusion ( D2) .Renal I/R was induced by removal of the right kidney and ligation of the left re-nal artery and vein followed by 3 hours of reperfusion.Meanwhile, intraperitoneal injection of DEX at 50μg/kg was given to the ani-mals in groups D1 and D2 at 60 at 120 min respectively after ischemia.After 3 hours of reperfusion, blood samples were collected for measurement of the concentrations of serum creatinine (Cr) and blood urea nitrogen (BUN), and renal and myocardial tissues harvested for observation of pathological changes under the light microscope and determination of the expressions of TNF-αand IL-10 by ELISA.Results Significant increases were observed in the concentrations of serum Cr and BUN , the expressions of TNF-αand IL-10 in the renal tissues and those in the myocardial tissues in groups I /R1([84.67 ±9.62] μmol/L, [8.55 ±1.08] mmol /L), I/R2 ([167.11 ±18.81] μmol/L, [13.42 ±1.25] mmol/L), D1 ([69.67 ±9.52] μmol/L, [7.56 ±0.70] mmol/L), and D2 ([114.29 ±12.50] μmol/L, [10.27 ±0.78] mmol/L), as compared with the sham operation group ([53.20 ±9.21] μmol/L, [3.75 ±0.78] mmol/L), (all P <0.05).Significant decreases was observed in the sham operation group as compared with other groups in the expressions of TNF-αand IL-10 (P<0.05).Significant decreases was observed in the D1 and D2 groups compared with other groups in the expressions of TNF-α, but increasing in IL-10.②Injury was reduced in the D1 and D2 groups compared with other groups.③The horizontal stripes of myocardial tissue disappeared in I/R1 and I/R2 decreases of inflammatory cells was observed in D1 and D2 groups compared with others. Conclusion Dexmedetomidine can attenuate myocar-dial injury induced by renal ischemia-reperfusion in rats and its inhibitory effect on inflammatory factors may be involved in the mechanism.

ABSTRACT

Objective To investigate the proliferation, immune phenotype and cytotoxicity on different cell lines of cytokine-induced killer (CIK) cells collected from healthy donors. Methods Peripheral blood mononuclear cells (PBMC) from healthy donors were induced to become CIK cells by adding cytokines including rhIL-2, rhIFN-γand CD3 McAb. The proliferation of CIK cells was tested by blood cell recording board. The CIK cells were analyzed on different time points by FACS. The cytotoxicity of CIK cells against different tumor cell lines, such as K562, BJAB, A549, MCF-7 and HepG2, was detected by MTT assays on day 13. Results CIK cells quickly proliferated from day 5, and expanded by 182-fold after 20-day culture. The immunophenotypes of CD3+, CD3+CD8+and CD3+CD56+were (97.83±1.03)%, (77.12±1.60)%and (27.58± 2.02)%. The percentages of CD3+, CD3+CD8+and CD3+CD56+increased noticeably (P<0.01). According to the effector-tar-get ratio of 40∶1, the activity of CIK cells against tumor cells K562, BJAB, A549, MCF-7 and HepG2 were (88.89±7.22)%, (75.42±9.52)%, (63.19±5.67)%, (43.53±5.67)%and (42.63±7.69)%. The experiments showed that CIK cells possessed high-er antitumor cytotoxic activity. Conclusion CIK cells can be largely capacity cultured by adding cytokines in vitro. CIK cells were a highly efficient cytotoxic cell against tumors, and had clinical application potentials.

ABSTRACT

OBJECTIVE: To observe the effects of Quyu Jiedu Granule, a compound traditional Chinese herbal medicine for removing blood stasis and expelling superficial evils, on the quality of oocytes and the expressions of tumor necrosis factor-alpha (TNF-alpha)and interleukin-6 (IL-6) mRNAs in ovarian granulosa cells of endometriosis (EM) rats. METHODS: Forty EM rats were randomly divided into two groups: experimental group and control group. There were 20 EM rats in each group. The uteri of another 20 SD rats were drawn in sham-operated group. The number and percentage of high quality oocytes and the levels of TNF-alpha and IL-6 mRNA expressions in the granulosa cells of EM rats were detected by using reverse transcription-polymerase chain reaction. RESULTS: The number and percentage of high quality oocytes in the experimental group were significantly higher than those in the control group (P<0.05), and the levels of TNF-alpha and IL-6 mRNAs in granulose cells in the experimental group were significantly lower than those in the control group (P<0.05). CONCLUSION: The increase of the TNF-alpha and IL-6 mRNA expressions in ovarian granulose cells of EM rats leads to the decrease of the oocyte quality. The mechanism of Quyu Jiedu Granule in improving the quality of oocytes may be related to the decrease of TNF-alpha and IL-6 mRNA expressions in ovarian granulosa cells.
