Objective:To systematically review the diagnostic value of 18F-fluorodeoxyglucose positron emission tomography/computed tomography(18F-FDG PET/CT)on recurrence or metastasis of patients with ovarian cancer whose postoperative serum carbohydrate antigen 125(CA125)occurred abnormal elevation.Methods:A systematic search was conducted in foreign databases,including PubMed,Embase,Cochrane Library(Central)and Web of Science(SCI-Expanded),as well as Chinese databases,such as China National Knowledge Infrastructure(CNKI),VIP Network,Wanfang Database,and China Biology Medicine(CBM),for the studies that were published between January 2010 and January 2023 on the diagnostic value of 18F-FDG PET/CT on recurrence or metastasis of patients with ovarian cancer whose postoperative serum CA125 levels occurred abnormal elevation.The quality of the included studies was assessed by using the QUADAS-2 quality evaluation tool in Review Manager 5.4 software.The effective data were extracted,and effect quantities were merged,and heterogeneity test was conducted through Meta-Disc 1.4 software.Publication bias of the included studies was tested by using Stata 14.0 software.Results:A total of seven literatures were involved in this research,and 290 patients with ovarian cancer were included to conduct heterogeneity test,which revealed I2 values all were greater than 50%.Therefore,the a fixed-effect model was used to merge effect quantity.The results demonstrated that the diagnostic accuracy was higher,and the sensitivity,specificity,positive likelihood ratio,negative likelihood ratio,and diagnostic odds ratio(DOR)of the mergement were respectively 0.95(95%CI:0.91-0.98),0.83(95%CI:0.70-0.92),4.84(95%CI:2.82-8.31),0.07(95%CI:0.04-0.13)and 73.53(95%CI:28.00-187.90).The area under curve(AUC)value of receiver operating characteristic curve(AUC)was 0.9527,and the diagnostic accuracy of 18F-FDG PET/CT for metastasis or recurrence in patients with ovarian cancer,whose postoperative serum CA125 levels occurred elevation,reached to 95.27%.Publication bias testing showed there was no evidence of publication bias.Conclusion:18F-FDG PET/CT exhibits higher accuracy in diagnosing recurrence or metastasis in patients with ovarian cancer whose postoperative serum CA125 levels occurred elevation,which can sensitively and accurately confirmed postoperative recurrence or metastasis of patients with ovarian cancer,and early find the lesions of metastasis or recurrence of ovarian cancer.

Purpose To investigate the distribution characteristics of tumor-associated macrophages(TAM)in different regions of breast cancer with enhanced contrast-enhanced ultrasound(CEUS),and to further explore the relationship between TAM and CEUS indicators and clinicopathology in different regions of breast cancer.Materials and Methods A total of 119 patients with suspected breast cancer admitted to the Cancer Hospital Affiliated to Xinjiang Medical University from March 2021 to March 2023 were prospectively included.CEUS was applied to the tumor,and ultrasound-guided puncture biopsy was also taken.The lesions diagnosed as breast cancer by pathology was outlined the central area,marginal area and normal area next to the cancer,and was obtained the time intensity curves of different areas.The tissues were taken for immunohistochemistry and flow cytometry,and the TAM cells were stained and distinguished.The characteristics of TAM in different regions of breast cancer and its correlation with clinical pathology were analyzed,respectively.Results By immunohistochemistry and flow cytometry,there were significant differences in the number of TAM infiltration in the border area,central area and adjacent area of breast cancer(immunohistochemistry:F=382.326,P<0.05;flow cytometry:F=24.955,P<0.05).The characteristics of CEUS in three different regions showed that the TAM in the central region of breast cancer increased when filling defect appeared(t=2.631,P<0.05),but the TAM in the peripheral region was more(t=2.999,P<0.05).After angiography,lesions showed high perfusion,and there was significantly more TAM in the edge and central area of the lesion than that in normal area next to the cancer(t=5.529,P<0.05;t=2.584,P<0.05).Clinical stage was related to the TAM in three regions.When the clinical stage was high,there were more TAM in all three regions(t=6.658,2.367,2.400,all P<0.05).Histological grading was high,and TAM in all three areas was high(F=101.151,16.922,26.822,all P<0.05).Conclusion There was a decreasing trend of TAM in the marginal area,central area and adjacent tissues of breast cancer during CEUS.The edge region has more malignant CEUS characteristics than that in the central region and the normal region adjacent to cancer;and the number of TAM is more in breast cancer with late clinical grading,poor tissue differentiation and obvious contrast-enhanced ultrasound malignant characteristics.The distribution characteristics of TAM represent the malignant degree and metastatic probability of breast cancer to a certain extent,and TAM is a factor related to the invasion of breast cancer.

Background: and Purpose The eye-movement examination can be applied as a noninvasive method to identify multiple-system atrophy (MSA). Few studies have investigated eye movements during the early stage of MSA with predominant parkinsonism (MSA-P). We aimed to determine the characteristic oculomotor changes in the early stage of MSA-P. Methods: We retrospectively selected 17 patients with MSA-P and 40 with Parkinson’s disease (PD) with disease durations of less than 2 years, and 40 age-matched healthy controls (HCs).Oculomotor performance in the horizontal direction was measured in detail using videonystagmography. Results: We found that the proportions of patients with MSA-P and PD exhibiting abnormal eye movements were 82.4% and 77.5%, respectively, which were significantly higher than that in the HCs (47.5%, p<0.05). Compared with HCs, patients with MSA-P presented significantly higher abnormal proportions of fixation and gaze-holding (17.6% vs. 0%), without-fixation (47.1% vs. 0%), prolonged latency in reflexive saccades (29.4% vs. 5.0%), memory-guided saccades (93.3% vs. 10.0%), and catch-up saccades in smooth-pursuit movement (SPM, 41.2% vs. 0) (all p<0.05). Compared with those with PD, patients with MSA-P presented a significantly higher proportion of catch-up saccades in SPM (41.2% vs. 2.5%, p<0.001). Conclusions MSA-P presented the characteristic of catch-up saccades in SPM in the early stage, which may provide some value in differentiating MSA-P from PD.

Charged particle therapy offers a better effect and obvious dosimetric and biological advantages over conventional radiotherapy in tumor control.Charged particles form Bragg peak in the dose distribution in tissue, enable most of energy to be deposited in the target region, and thus enhance tumor control and reduce the damage to normal tissues surrounding the tumor.With the increasing demand for charged particle therapy and the advances in particle accelerator, particle therapy technology is developing rapidly.The core apparatus of particle therapy facility is particle accelerator, and the accelerator type, particle type, and implementation technique determine the performance and therapeutic effect of the facility.This article provides a detailed comparative analysis of various particle therapies.Statistical data show that proton therapy is dominant in particle therapy, and high construction difficulty, large facility size, and extremely high cost have limited the development of heavy ion therapy.Nowadays, there are still some technical problems regarding charged particle therapy, and more clinical trials are required.

OBJECTIVETo study the value of compute tomography (CT)-based quantitative assessment in the diagnosis of pneumoconiosis.

METHODSSixty patients with pneumoconiosis and 40 healthy volunteers (control) underwent CT scanning at the levels of the top of the aortic arch, tracheal carina, and 3 cm and 6 cm below the tracheal carina. All the CT images were analyzed with density histograms for a specific region to calculate the mean lung CT value (ME) and pixel index for assessment of lung density changes.

RESULTSAt the levels of the top of the aortic arch and 6 cm below the tracheal carina, the pixel indices in the 10 CT threshold density intervals within -832 to -352 HU was all significantly higher in pneumoconiosis group than in the control group (P<0.05). At the levels of the tracheal carina and 3 cm below the tracheal carina, the 11 pixel indices in the CT threshold density intervals within -880 to -352 HU were also significantly higher in pneumoconiosis group (P<0.05). At all the 4 scan levels, the pixel indices in the 10 intervals between -880 and -352 HU were all significantly higher in pneumoconiosis group (P<0.05).

CONCLUSIONCT density histograms allow quantitative evaluation of lung fibrosis in patients with pneumoconiosis for diagnostic purposes.
