Comparison of clinical utility of 18F-FAPI-42 and 18F-FDG PET/CT imaging in the diagnosis of newly diagnosed lung cancer / 中华核医学与分子影像杂志

Objective:To compare the clinical utility of 18F-fibroblast activating protein inhibitor (FAPI)-42 and 18F-fluorodeoxyglucose (FDG) PET/CT imaging in newly diagnosed lung cancer patients. Methods:From May 2020 to September 2021, the images of 43 lung cancer patients (32 males, 11 females, age: 37-80 years) who pathologically confirmed and received 18F-FDG and 18F-FAPI-42 PET/CT within 2 weeks in the First Affiliated Hospital of Guangzhou Medical University were prospectively analyzed. The maximum standardized uptake value (SUV max) of 18F-FDG and 18F-FAPI-42 and the number of lesions detected by 2 imaging methods were compared by using paired t test and Wilcoxon rank sum test. Results:The 43 newly diagnosed lung cancer patients included 35 adenocarcinoma, 2 squamous cell carcinoma, 4 small cell lung cancer, and 2 high-grade neuroendocrine tumors. 18F-FAPI-42 had a very high tumor uptake (SUV max: 12.24±3.97) and lesion detection rate (positive rate: 100%(37/37)) in primary lung adenocarcinoma and squamous cell carcinoma. The uptake of 18F-FAPI-42 in lymph node (10.13±5.43), pleura (6.75(4.96, 8.58)) and bone lesion (7.18(4.33, 9.66)) were significantly higher than those of 18F-FDG (6.35±3.30, 2.69(1.81, 5.00), 4.38(2.96, 6.36); t=12.19, z values: 5.47, 5.79, all P<0.001). In lung adenocarcinoma and squamous cell carcinoma, although the uptake of 18F-FAPI-42 in brain metastases was significantly lower than that of 18F-FDG (0.72(0.15, 1.82) vs 6.53(4.65, 9.34); z=6.42, P<0.001), the tumor/background (T/B) ratio was significantly higher than that of 18F-FDG (3.54(1.15, 14.88) vs 0.96(0.77, 1.04); z=6.05, P<0.001). In lung adenocarcinoma and squamous cell carcinoma, the number of lesions detected by 18F-FAPI-42 PET/CT was significantly more than that of 18F-FDG (lymph node: 6.0(2.3, 11.5) vs 4.5(2.0, 10.8); brain: 2.0(1.0, 3.0) vs 0.0(0.0, 0.0); pleura: 6.0(2.8, 10.0) vs 4.0(0.8, 5.5); z values: 2.16, 3.10, 2.04, all P<0.05). However, in high-grade neuroendocrine tumors and small cell lung cancer, the SUV max of 18F-FAPI-42 in primary lesions (8.05±2.60), lymph node lesions (5.98±2.21) and brain lesions (0.44(0.13, 0.82)) were lower than those of 18F-FDG (16.28±5.17, 12.30±5.47, 4.94(4.84, 6.25); t values: 3.58, 7.52, z=3.06, all P<0.05). Conclusions:In lung adenocarcinoma and squamous cell carcinoma, 18F-FAPI-42 has a very high tumor uptake and lesion detection rate in primary tumor. In addition, compared with 18F-FDG PET/CT, 18F-FAPI-42 PET/CT shows clearer tumor contours and more lesions. Therefore, 18F-FAPI-42 is more suitable for preliminary staging of lung adenocarcinoma and squamous cell carcinoma than 18F-FDG, while the opposite is true in small cell lung cancer and high-grade neuroendocrine tumors.

Preliminary exploration of reserved talents training in thoracic surgery / 中华医学教育探索杂志

Based on the Nanshan class of clinical medicine in Guangzhou Medical University, the center established an interest-oriented thoracic surgery learning collaboration group. All recruited students received the full-range cultivation, including "MDT" learning collaboration with characteristics of early clinical practice, early scientific research, English training and thoracic surgery collaboration group as thecore, accelerated clinical skills training under the naked-eye 3D thoracoscopic system, and scientific research thinking which recommended by new media — "WeChat public platform". A total of 10 undergraduate students from 2013 to 2017 batch were recruited into the this group and they showed advantages in clinical technique, scientific research and higher education enrollment after cultivation, demonstrating that part of the clinical teaching and scientific research thinking of thoracic surgery gave to undergraduates in advance can pave the way for the training of thoracic surgeons and formulate more detailed and individualized programs to teach students in accordance with their aptitude in the future.

Analysis of HPA1-16 and HLA-A, B gene polymorphisms among ethnic Han population from Shandong / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To study the polymorphisms of human platelet antigen (HPA) 1-16 and human leukocyte antigen (HLA)-A and -B loci among ethnic Han population from Shandong.</p><p><b>METHODS</b>A total of 588 samples from platelet donors were genotyped for the above loci with sequence-specific primer PCR and sequence-specific oligonucleotide probe PCR.</p><p><b>RESULTS</b>The frequencies of HPA-la, -1b, HPA-2a, -2b, HPA-3a, -3b, HPA-4a, -4b, HPA-5a, -5b, HPA-6a, -6b, HPA-15a, -15b were 0.9974, 0.0026, 0.9456, 0.0544, 0.5417, 0.4583, 0.9983, 0.0017, 0.9889, 0.0111, 0.9903, 0.0097, 0.5434 and 0.4583, respectively. The HPA-7-14 and HPA-16 showed no heterozygosity as the b allele was not detected in such loci. The most common genotypic combination for HPA was HPA-(1,4,7-14,16,17) aa-2aa-3ab-5aa -6aa-15ab (0.1820). HLA-A2 (0.3070) and HLA-B13 (0.1361) demonstrated the highest frequencies at their respective loci.</p><p><b>CONCLUSION</b>The HPA and HLA loci are highly polymorphic among ethnic Hans from Shandong. The distribution of HPA polymorphisms also shows a great ethnic and territorial difference. It is important to construct regional database for the genotypes of HPA and HLA loci for platelet donors.</p>
