In recent years, chimeric antigen receptor T-cell (CAR-T) therapy has shown a certain value in the treatment of malignant hematological tumors, especially for patients with relapsed/ refractory B-cell lymphoma. Currently, 18F-FDG PET-CT has proved its great clinical values in the diagnosis and treatment of lymphoma. There are relatively few studies using 18F-FDG PET-CT to evaluate B-cell lymphoma treated by CAR-T therapy, but some good results have also been achieved. This paper reviews the current research progress of 18F-FDG PET-CT in CAR-T therapy for B-cell lymphoma.

Objective:To investigate the response of mandibular condylar chondroprogenitors to flow fluid shear stress(FFSS).Methods:Chondroprogenitors were in vitro cultured and stimulated with FFSS that can cause cell degeneration,and treated with sec-ond-generation high-throughput RNA sequencing.Differential gene expression was screened using DESeq2 software for gene ontology(GO)functional enrichment analysis,kyoto encyclopedia of genes and genomes(KEGG)pathway enrichment analysis and protein-protein interaction(PPI)network analysis.qRT-PCR was performed to validate the core genes screened by PPI.Results:A total of 1996 differentially expressed genes were obtained,mainly including inflammatory response and cell cycle related molecules.Among them,Actal,Atf3,Ccl2,116,Nfkbia,Ret and Vcaml were identified as the core genes.Conclusion:FFSS stimulation affects chondroprogenitor function by acting on inflammatory responses and cell cycle-related signaling pathways in chondroprogenitors.

Objective To investigate the predictive value of a nomogram model constructed based on imaging combined with prostate-specific antigen(PSA)and its related parameters for biopsy in patients with PSA levels of 4-10 ng/mL.Methods The serological and imaging data of 191 patients who were detected for PSA and related indicators and underwent the first biopsy of prostate by transrectal ultrasound at Zhongshan City People's Hospital and/or Yunfu Hospital of TCM from January 2018 to December 2023 were analyzed retrospectively.Multivariate Logistic regression identified independent risk factors for prostate cancer,and a nomogram model was developed for patients with PSA levels of 4-10 ng/mL.The predictive performance of the model was evaluated using receiver operating characteristic(ROC)curves,calibration curves,and decision curves.Results The multivariate Logistic regression analysis showed that free PSA,prostate volume,transition zone volume,PSA density,and the prostate imaging-reporting and data system(PI-RADS v2.1)score were independent risk factors for prostate cancer.The model incorporating these significant variables demonstrated the best performance,with an area under the curve(AUC)of 0.750(95%CI:0.678-0.821),sensitivity of 72.7%,specificity of 77.2%,and accuracy of 74.9%.The calibration curve indicated good agreement between the predicted probability and the actual probability of prostate cancer;and the decision curve analysis further confirmed that the model had high clinical utility.Conclusion The constructed nomogram prediction model can effectively estimate the preoperative risk of prostate cancer in patients with PSA levels of 4-10 ng/mL,providing clinicians with an intuitive tool to adjust treatment plans based on the assessed risk,thereby optimizing patient outcomes.

Objective:To investigate the diagnosis, treatment and aeromedical assessment of military flying personnel with cerebral cavernous malformations (CCM).Methods:The clinical data and aeromedical assessment conclusions of military flying personnel with CCM in Air Force Medical Center from 2015 to 2021 were collected and analyzed based on reviewing the relevant aeromedical assessment cases and literatures at home and abroad.Results:A total of 10 flying personnel, all male, 20-41 years old, with an average age of 28.3 years, including 8 pilots, 2 air combat/technical personnel, with the flying hours of 110-4 000 h and the average flying hours of 1 102.0 h. The sizes of lesions were 3-12 mm, including 2 cases were smaller than 5 mm, 6 cases were 5-10 mm and 2 cases were bigger than 10 mm. All lesions were located under the cortex, including a case of occipital lobe, 4 cases of frontal lobe, 2 cases of temporal lobe and 3 cases of cerebellar hemisphere. Among the 10 flying personnel, only a case presented intracranial haemorrhage (right cerebellar hemisphere) as first symptom and was treated surgically. Three cases were temporarily grounded due to they were under the grounding observation. Other 7 flying personnel had been followed up for more than 6 months. Their reexaminations of MRI showed no change in lesions and EEG examination showed no abnormalities. Two air combat/technical personnel were qualified for flight and 1 helicopter pilot was limited to be a co-pilot, and 2 dual-seat fighter pilots were qualified (limited to dual-seat fighter) and flight-qualified respectively. Two fighter pilots were qualified for lower performance aircraft (limited to bomber, transporter or helicopter).Conclusions:For CCM military flying personnel, the aeromedical assessment conclusion should be made according to the symptoms, lesion location and size, inflight incapacitation possibility assessment, treatment effect, ground observation and follow-up results, as well as the aircraft type and occupation.

Objective:To analyze the trend of disease burden of oral cancer attributable to smoking in China from 1990 to 2019, and predict the mortality trend of oral cancer from 2020 to 2034, providing scientific basis for formulating targeted oral cancer prevention and treatment strategy to achieve the goal of "Healthy China 2030".Methods:Using partial data on the global burden of disease in China in 2019, attributive death and disability adjusted life year (DALY) were used to describe. The trend of changes in the burden of oral cancer disease attributed to smoking was analyzed by using the Joinpoint regression model to estimate the annual average percentage change (AAPC) of age standardized mortality and DALY rates. Meanwhile, the Bayesian age-period- cohort model is used to predict oral cancer deaths and DALY trends attributed to smoking over the next 15 years.Results:The age-standardized mortality rate and DALY rate in China from 1990 to 2019 showed an overall upward trend, with an average annual increase of 1.49% (95 %CI: 1.34%-1.65%, P<0.001) and 1.41% (95 %CI: 1.24%-1.59%, P<0.001) respectively, higher than around the earth and in regions with different socio-demographic index (SDI). In 2019, 46.74% (10 584/22 642) of oral cancer deaths in China were attributed to smoking. Compared to 1990, the number of attributed deaths in 2019 increased by 293.75% (7 896/2 688), while DALY increased by 257.97% (189 039/73 280). Moreover, the growth rates of attributed deaths and DALY in males [304.95% (7 584/2 487) and 265.60% (183 349/69 033), respectively] were significantly higher than those in females [154.73% (311/201) and 133.95% (5 690/4 248), respectively] ( P<0.001). The age group results showed that the proportion of deaths and DALY gradually transitioned towards the elderly (>60 years old). The expected number of deaths would increase from 10 731 in 2020 to 14 125 in 2034, with a rise of 31.63% (3 394/10 731). Simultaneously, DALY would increase from 267 064 person years in 2020 to 326 634 person years in 2034, with a rise of 22.31% (59 570/267 064). Conclusions:From 1990 to 2019, the burden of oral cancer diseases attributed to smoking in China showed an increasing trend, with a higher growth rates than in the global and different SDI regions. There were differences in gender and age, and the burden of oral cancer diseases attributed to smoking in China would continue to increase in the next 15 years. It is necessary to educate on the adverse effects of tobacco consumption and to conduct vigilant oral self-examination among high-risk groups to help early detection and intervention at the same time.
