Macrophages are closely related to tumor progression,and can promote tumor growth and pro-liferation by promoting inflammation,angiogenesis and immunosuppression and so on,as well as killing tumors by directly killing tumor cells and triggering specific immune responses.Iron death,as an iron-depend-ent cell death caused by lipid peroxidation,can effectively kill tumor cells when regulated from the perspective of iron homeostasis,and can also release pro-inflammatory factors,trigger inflammatory reactions,change the survival environment of tumors as well as reduce the immune susceptibility of tumor cells.In recent years,more and more studies have shown that macrophages and iron death are closely related.In this paper,the rela-tionship between macrophages and iron death in terms of their functional properties and targeting of tumors are mainly introduced,and an overview of the functional properties of the two differentiated phenotypes of macrophages for the treatment of iron death in tumors is provided.

Objective:To compare the efficacy and safety among traditional open suture, modified Kessler method, and minimally invasive suture with threaded rivets in acute closed Achilles tendon rupture.Methods:A total of 60 patients with acute closed Achilles tendon rupture diagnosed and treated in the Affiliated Hospital of Jining Medical College from January 2018 to August 2022 were selected retrospectively as the study subjects and divided into group A (20 patients with traditional open suture), group B (20 patients with modified Kessler method) and group C (20 patients with minimally invasive suture with threaded rivets) according to operative method. The clinical efficacy, perioperative indexes, Achilles tendon activity, postoperative recovery work and exercise time, visual analog scale (VAS) score and complications were compared among the three groups.Results:The total effective rate in the group C was higher than that in the group A : 18/20 vs. 12/20, there was statistical difference ( χ2 = 4.80, P<0.05). The total effective rate in the group B and group C had no statistical difference ( P>0.05). The operation time, intraoperative blood loss, incision length, hospitalization time, time to return to work, exercise and VAS scores in the group B and group C were lower than those in the group A: (49.32 ± 4.74), (48.12 ± 4.68) min vs. (66.71 ± 5.84) min; (15.32 ± 1.01), (15.62 ± 0.79) ml vs.(19.86 ± 1.20) ml; (7.69 ± 0.57), (3.76 ± 0.50) cm vs. (8.98 ± 0.62) cm; (7.01 ± 0.91), (6.82 ± 0.83) d vs.(8.74 ± 1.12) d; (56.32 ± 8.01), (55.17 ± 7.84) d vs. (63.17 ± 6.68) d; (6.13 ± 1.20), (5.94 ± 1.04) months vs. (8.21 ± 1.20) months; (2.76 ± 0.50), (2.55 ± 0.76) scores vs. (3.98 ± 0.62) scores, there were statistical differences ( P<0.05). At 1, 6 and 12 months after surgery, the American Society for Foot and Ankle Surgery (AOFAS) scores in the three groups were significantly increased, and the AOFAS scores in the group B and group C were higher than those in the group A, there were statistical differences ( P<0.05). The total incidence of complications in the group C was lower than that in the group A: 2/20 vs. 8/20, there was statistical difference ( χ2 = 4.80, P<0.05). The total incidence of complications in the group B and group C had no statistical difference ( P>0.05). Conclusions:Modified Kessler method and minimally invasive suture with threaded rivets have the advantages of high efficiency and safety in the treatment of acute closed Achilles tendon rupture, and their efficacy is higher than that of traditional open suture.

AIM: To explore the correlation between remnant cholesterol(RC)and anterior ischemic optic neuropathy(AION).METHODS: A total of 80 cases of AION patients hospitalized in the department of ophthalmology of Linyi People's Hospital from January 2020 to December 2023 were selected as the observation group, and 80 cases of those who had completed health checkups in Linyi People's Hospital during the same period(without ischemic optic neuropathy and other fundus vasculopathies)were selected as the control group. The general data and biochemical indexes of the two groups were compared to evaluate the correlation between RC and AION.RESULTS: Compared with the control group, the levels of RC, fasting blood glucose(FBG), triglyceride(TG), total cholesterol(TC), and low-density lipoprotein cholesterol(LDL-C)in patients with AION were significantly higher than those in the control group(all P<0.01). Spearman correlation analysis showed that RC was positively correlated with TG, TC, and LDL-C(all P<0.01). Logistic regression analysis showed that RC and FBG were risk factors for the development of AION. The analysis of receiver operating characteristic(ROC)curves showed that the level of RC had a better predictive value for the development of AION compared with FBG.CONCLUSION: RC is associated with the development of AION and is a risk factor for the development of AION. Clinical standardization of the management of people with high RC values can reduce the risk of the development of AION, which is of clinical significance.

The biological samples of oral genetic diseases and rare diseases are extremely precious. Collecting and preserving these biological samples are helpful to elucidate the mechanisms and improve the level of diagnose and treatment of oral genetic diseases and rare diseases. The standardized construction of biobanks for oral genetic diseases and rare diseases is important for achieving these goals. At present, there is very little information on the construction of these biobanks, and the standards or suggestions for the classification and coding of biological samples from oral and maxillofacial sources, and this is not conducive to the standardization and information construction of biobanks for special oral diseases. This consensus summarizes the background, necessity, principles, and key points of constructing the biobank for oral genetic diseases and rare diseases. On the base of the group standard "Classification and Coding for Human Biomaterial" (GB/T 39768-2021) issued by the National Technical Committee for Standardization of Biological Samples, we suggest 76 new coding numbers for different of biological samples from oral and maxillofacial sources. We hope the consensus may promote the standardization, and smartization on the biobank construction as well as the overall research level of oral genetic diseases and rare diseases in China.

OBJECTIVE: To investigate the intra- and inter-scanner reproducibility of quantitative susceptibility mapping (QSM) of cerebral subcortical nuclei in healthy adults. METHODS: QSM was performed in 21 healthy adults on two different 3.0T MR scanners, and the region of interest (ROI) method was used to measure the magnetic susceptibility value of the left subcortical nuclei (the head of the caudate, putamen, globus pallidus, thalamus, substantia nigra and red nucleus). The intraclass correlation coefficient (ICC) and Bland-Altman method were used to evaluate the inter-scanner and intra-scanner reliability. RESULTS: The ICCs of the susceptibility value ranged from 0.90 to 0.99 for all the subcortical gray nuclei except for the head of the caudate nucleus measured on the same MR scanner by the same observer. Bland-Altman analysis revealed that the points with susceptibility differences for all the subcortical gray nuclei except for substantia nigra located in the 95% CI of limits of agreement for the same MR scanner. The ICCs of the susceptibility value for the inter-scanner was 0.49 (0.08-0.75) for the head of the caudate nuleus, 0.80 (0.57-0.91) for the putamen, 0.77 (0.51-0.90) for the globus pallidus, 0.78 (0.54-0.91) for the thalamus, 0.80 (0.56-0.91) for the substantia nigra and 0.93 (0.83-0.97) for the red nucleus. The points with susceptibility difference (95.2%, 20/21) located in the 95% CI of limits of agreement for the putamen and the thalamus measured on two different MR scanners. CONCLUSIONS The intra-scanner reproducibility of QSM of the subcortical gray nuclei is superior to the inter-scanner reproducibility in healthy adults.

Objective: To evaluate the application of calcium suppressed (CaSupp) spectral CT technique in evaluating disk position and measuring the thickness of the posterior band of temporomandibular joint (TMJ). Methods: The twenty-three temporomandibular disorder patients [mean age 23(12~62) years, male/female=14/9] were performed with oblique sagittal and coronal proton density weighted imaging (PDWI) and spectral CT scans from February to July, 2019 in Department of Radiology, Hainan Hospital of General Hospital of Chinese PLA, and 45 TMJ joints were evaluated. The subjects were classified into two groups according to the scanning modalities: MRI measurement group and CaSupp spectral-based CT group. The CaSupp technique were applied with the spectral-based CT images and CaSupp images were generated. The oblique sagittal and coronal CaSupp imaged were reformatted by perpendicular to the long axis of the condyle. The TMJ disk positions were evaluated on oblique sagittal and coronal images, and the maximal disk thickness were measured on the oblique sagittal images. Results: The joint position was basically consistent on MRI and CaSupp images for the 45 TMJ joints. The intra-class coefficient value was 0.843 (0.712, 0.914) for the measurement of the posterior band of the TMJ disk between MRI and CaSupp images. Bland-Altman presented that the [95.6% (43/45)] points with the difference located in the 95% agreement interval. Wilcoxon paired text demonstrated that there was no significant different for the thickness of the posterior band between MRI [2.57 (1.76, 3.65) mm] and CaSupp images [2.67 (1.74, 4.56) mm] (P=0.07). Conclusions The CaSupp spectral-based CT could be used to evaluated the TMJ disk position and the thickness of the posterior band.

From December 2019, Coronavirus disease 2019 (COVID-19) pneumonia (formerly known as the 2019 novel Coronavirus [2019-nCoV]) broke out in Wuhan, China. In this study, we present serial CT findings in a 40-year-old female patient with COVID-19 pneumonia who presented with the symptoms of fever, chest tightness, and fatigue. She was diagnosed with COVID-19 infection confirmed by real-time reverse-transcriptase-polymerase chain reaction. CT showed rapidly progressing peripheral consolidations and ground-glass opacities in both lungs. After treatment, the lesions were shown to be almost absorbed leaving the fibrous lesions.
