The diagnosis of occupational radiation diseases, with the diagnostic criteria as main technical basis, has always been one of the emphases of China's occupational health work. This study compared the diagnostic standards for occupational radiation diseases between China and the International Labour Organization (ILO) across three aspects—types, classifications/grades, and diagnostic dose requirements—categorizing the diseases into tissue reactions and stochastic effects. ① For tissue reactions, 8 types are included both in China and ILO standards, 13 unique to China's standards, and 4 unique to the ILO standards; significant differences exist in classifaton/grading; China's standards are either consistent with or stricter (i.e., requiring higher diagnostic dose values) than the ILO standards. ② For stochastic effects (radiation-induced cancer), 12 types were included in both standards; China's standards provide more comprehensive coverage for certain malignancies (e.g., bone cancer); while 5 types were unique to the ILO standards have, some (e.g. salivary gland cancer) are primarily observed in non-occupational populations. Overall, China’s standards include more disease types and maintain more stringent diagnostic dose requirements. However, specific discrepancies require further deliberation during future revisions. Finally, based on these results, recommendations were provided for basic research and the evaluation of Chinese diagnostic criteria.

Objective A randomized controlled trial was conducted on colonoscopy inpatient and outpatients to compare the efficacy and safety of water exchange(WE)colonoscopy and CO2 convention insufflation colonoscopy in elderly patients.Methods 340 patients underwent fully sedated colonoscopy were randomly divided into two groups according to colonoscopy with either WE colonoscopy group(WE group)and CO2 insufflation colonoscopy group(CO2 group).The two groups were compared in terms of Boston bowel preparation scale(BBPS),withdrawal time,cecal intubation time,cecal intubation success rate,abdominal compression,willingness to repeat,polypdetectionrate(PDR),adenoma detection rate(ADR),and safety.Results The cecal intubation success rate was significantly higher in WE group(100.0%)compared with CO2 group(96.5%),the difference was statistically significant(P=0.013).The average cecal intubation time of WE group was(10.50±1.79)min,which was longer than that of CO2 group(7.55±1.50)min,and the difference was statistically significant(P<0.01).Comparison of withdrawal time and BBPS between the two groups,the differences were not statistically significant(P>0.05).The abdominal pressure rate was lower in WE group(5.9%)compared with CO2 group(13.5%),the difference was statistically significant(P=0.017).The rate of willingness to re-examination in the WE group was 98.2%,which was significantly higher than the 93.5%in the CO2 group.The PDR in WE group(80.6%)was higher than that in CO2 group(70.6%),the ADR in WE group(67.1%)was higher than that in CO2 group(50.6%),the differences were statistically significant(P<0.05).Multivariate Logistic regression analysis showed that WE group was an effective factor in improving ADR(O＾R=2.027,P<0.01).The overall adverse events were less than 3%,with no difference between the two groups(P=1.000).Conclusion The use of WE colonoscopy has a better improved efficacy in elderly patients,and safety should be ensured by individualized assessment of the patient's co-morbidities,bowel preparation tolerance,and willingness prior to the procedure.

During the hyperacute phase of intracerebral hemorrhage (ICH), the mass effect and blood components mechanically lead to brain damage and neurotoxicity. Our findings revealed that the mass effect and transferrin precipitate neuronal oxidative stress and iron uptake, culminating in ferroptosis in neurons. M6A (N6-methyladenosine) modification, the most prevalent mRNA modification, plays a critical role in various cell death pathways. The Fto (fat mass and obesity-associated protein) demethylase has been implicated in numerous signaling pathways of neurological diseases by modulating m6A mRNA levels. Regulation of Fto protein levels in neurons effectively mitigated mass effect-induced neuronal ferroptosis. Applying nanopore direct RNA sequencing, we identified voltage-dependent anion channel 3 (Vdac3) as a potential target associated with ferroptosis. Fto influenced neuronal ferroptosis by regulating the m6A methylation of Vdac3 mRNA. These findings elucidate the intricate interplay between Fto, Vdac3, m6A methylation, and ferroptosis in neurons during the hyperacute phase post-ICH and suggest novel therapeutic strategies for ICH.

High-quality standard drafting is the foundation for ensuring the effective implementation of radiological health standards. Based on the current standard drafting requirements and the practices in drafting and reviewing radiological health standards in recent years, this article analyzed and discussed the connotations of three principles of standardized document expression, including consistency, coordination, and usability, as well as their application in standard drafting. This article summarized the important considerations during drafting and provided reasonable suggestions, which can be used as a reference for standardization professionals.

HDAC7, a member of class IIa HDACs, plays a pivotal regulatory role in tumor, immune, fibrosis, and angiogenesis, rendering it a potential therapeutic target. Nevertheless, due to the high similarity in the enzyme active sites of class IIa HDACs, inhibitors encounter challenges in discerning differences among them. Furthermore, the substitution of key residue in the active pocket of class IIa HDACs renders them pseudo-enzymes, leading to a limited impact of enzymatic inhibitors on their function. In this study, proteolysis targeting chimera (PROTAC) technology was employed to develop HDAC7 drugs. We developed an exceedingly selective HDAC7 PROTAC degrader B14 which showcased superior inhibitory effects on cell proliferation compared to TMP269 in various diffuse large B cell lymphoma (DLBCL) and acute myeloid leukemia (AML) cells. Subsequent investigations unveiled that B14 disrupts BCL6 forming a transcriptional inhibition complex by degrading HDAC7, thereby exerting proliferative inhibition in DLBCL. Our study broadened the understanding of the non-enzymatic functions of HDAC7 and underscored the importance of HDAC7 in the treatment of hematologic malignancies, particularly in DLBCL and AML.

Objective To evaluate the clinical efficacy of robot-assisted navigation with percutaneous lag screw treatment for Hangman's fracture.Methods We retrospectively analyzed the clinical data of 5 patients treated with robot-assisted C2 percutaneous lag screw for Hangman's fracture in our hospital from September 2021 to August 2023.Patients were positioned with moderate head-neck flexion in a Mayfield head clamp.After closed reduction with manual traction under general anesthesia,the C2 percutaneous lag screws were implanted under TINAVI orthopedic surgical robot assistance.Postoperative cervical CT scans were used to assess screw placement accuracy and fracture healing quality.Clinical efficacy was evaluated by the Odom grading system.Results All the 5 patients were operated successfully without vertebral artery injury or neurological complications.A total of 10 screws were implanted.According to the Gertzbein-Robbins standard,9 screws belonged to the grade A,and 1 belonged to the grade B,with an accuracy of 90％(9/10)and an excellent rate of 100％(10/10).The neck incision length ranged 20-30 mm(mean,27 mm).The operation time was 86-160 min(mean,112.8 min).The intraoperative blood loss was 10-50 ml(mean,30 ml).The postoperative hospitalization was5-18 d(mean,8 d).The patients were followed up for 12-34 months(mean,23.6 months).All fractures healed without screw breakage or loosening.According to the Odom grading,4 cases were excellent,and 1 case was good.Conclusion Robot-assisted navigation C2 percutaneous lag screw treatment for Hangman's fracture is accurate and minimally invasive,safe and effective.
