Objective:To investigate the effects of silicon photomutipliers (SiPM) detector and Bayesian penalized likelihood (BPL) reconstruction algorithm on semiquantitative parameters of 18F-FDG PET/CT and diagnostic efficiency for solitary pulmonary nodules/masses compared with traditional photomultiplier tube (PMT) and ordered subsets expectation maximization (OSEM). Methods:From March 2020 to January 2022, 118 patients (76 males, 42 females, age (63.0±10.1) years) newly diagnosed with solitary pulmonary nodules/masses in First Hospital of Shanxi Medical University were prospectively enrolled and underwent 18F-FDG PET/CT imaging with two different PET/CT scanners successively. The images were divided into PMT+ OSEM, SiPM+ OSEM and SiPM+ BPL groups according to PET detector and reconstruction algorithms. The SUV max, SUV mean, metabolic tumor volume (MTV) and total lesion glycolysis (TLG) of pulmonary nodules/masses were measured, then signal-to-noise ratio (SNR) and signal-to-background ratio (SBR) were calculated. One-way analysis of variance and Kruskal-Wallis rank sum test were performed to compare differences of above parameters among groups. ROC curve analysis was used to analyze the optimal threshold of SUV max for the differential diagnosis of pulmonary nodules/masses and AUCs were obtained. Results:There were 83 malignant nodules and 35 benign nodules. The image quality of SiPM+ BPL group (4.23±0.64) was better than that of SiPM+ OSEM group (3.57±0.50) or PMT+ OSEM group (3.58±0.51; F=54.85, P<0.001). There were significant differences in SUV max (7.57(3.86, 15.61) vs 4.95(2.22, 10.48)), SUV mean (4.43(2.28, 9.12) vs 2.84(1.21, 5.71)), MTV (3.54(1.57, 7.67) vs 5.09(2.83, 11.79)), SNR (28.12(12.55, 54.38) vs 20.16(8.29, 41.45)) and SBR (4.03(1.83, 7.75) vs 2.32(0.96, 5.03)) between SiPM+ BPL and SiPM+ OSEM groups ( H values: 16.63-37.05, all P<0.001). The optimal threshold values of SUV max in SiPM+ BPL, SiPM+ OSEM and PMT+ OSEM were 3.31, 2.21, 2.05 with AUCs of 0.686, 0.689, 0.615 for nodules < 2 cm, and were 10.29, 6.49, 4.33 with AUCs of 0.775, 0.782, 0.774 for nodules/masses ≥2 cm. Conclusions:Image quality and parameters of pulmonary nodules/masses are mainly affected by the reconstruction algorithms. BPL can improve SUV max, SUV mean, SBR and SNR, but reduce MTV without significant effect on liver parameters. SiPM+ BPL has a higher diagnostic threshold of SUV max than SiPM+ OSEM and PMT+ OSEM.

Objective:To investigate the effect of transcatheter arterial chemoembolization (TACE) combined with ultrasound-guided radiofrequency ablation (RFA) on the efficacy and immune function in patients with primary liver cancer.Methods:The clinical data of 152 patients with primary liver cancer from February 2019 to February 2021 in the Second Affiliated Hospital of Xi′an Jiaotong University were retrospectively analyzed. Among them, 76 patients were treated with TACE combined with RFA (combined group), and 76 patients were treated with TACE (control group). The efficacy was compared; the α-L fucosidase, T lymphocyte subsets (CD 3, CD 4, CD 8 and CD 4/CD 8), B lymphocyte subsets (CD 19) and tumor markers (alpha-fetoprotein, AFP; carcinoembryonic antigen, CEA; carbohydrate antigen 125, CA125) before treatment and 1 month after treatment were detected. Results:The total clinical effective rate in combined group was significantly higher than that in control group: 81.58% (62/76) vs. 52.63% (40/76), and there was statistical difference ( χ2 = 4.54, P<0.05). There were no statistical difference in all indexes before treatment between 2 groups ( P>0.05); the α-L fucosidase, AFP and CD 8 1 month after treatment in combined group were significantly lower than those in control group: (18.06 ± 5.33) U/L vs. (26.58 ± 7.75) U/L, (87.93 ± 22.55) μg/L vs. (146.83 ± 21.85) μg/L and 0.295 ± 0.052 vs. 0.367 ± 0.064, the CD 3, CD 4 and CD 4/CD 8 were significantly higher than those in control group (0.489 ± 0.054 vs. 0.462 ± 0.063, 0.363 ± 0.059 vs. 0.303 ± 0.075 and 1.43 ± 0.27 vs. 0.89 ± 0.14), and there were statistical differences ( P<0.01 or<0.05); there was no statistical difference in CEA, CA125 and CD 19 1 month after treatment between 2 groups ( P>0.05). Conclusions:TACE combined with RFA in the treatment of primary liver cancer patients can not only improve the total clinical effective rate, but also significantly improve the immune function, and help to reduce level of the liver tumor marker of AFP.

Objective:To investigate the correlation between neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and central lymph node metastasis (CLNM) in patients with cN0 papillary thyroid microcarcinoma (PTMC).Methods:The clinicopathological data of PTMC patients confirmed by surgery and pathology in the 81 st Military Hospital of People′s Liberation Army from 2016 to 2019 were collected, and the relationship between preoperative NLR, PLR levels and postoperative PTMC CLNM were analyzed. Logistic regression analysis was used for multivariate analysis. Receiver operating characteristic (ROC) curve was used to determine the cutoff value of NLR and PLR. The interaction relative excess risk was used to analyze the relationship between NLR, PLR and CLNM. Results:Among 220 patients with cN0 stage PTMC, 92 were CLNM. The ROC curve showed that when the cutoff value of NLR was 2.5 and the cutoff value of PLR was 175, the highest Youden index was 0.318 and 0.264, respectively. NLR and PLR were both related to CLNM ( P<0.05). The tumor long diameter, multifocality, NLR≥2.5 and PLR≥175 were independent impact factors of CLNM ( P<0.05). The results of the interaction showed that the relative excess risk of the interaction was 5.531 (95% CI: 0.160, 10.901, P=0.016), the attribution ratio was 0.512 (95% CI: 0.230, 0.794, P=0.009), and the synergy index was 2.294 (95% CI: 1.492, 4.579, P=0.022), suggested that NLR and PLR had an interactive effect, and these two synergistically promoted CLNM. Conclusions:NLR and PLR are independent risk factors for cN0 stage PTMC CLNM. When NLR≥2.5 and PLR≥175, preventive central lymph node dissection should be routinely performed.
