Objective:To comprehensively evaluate the performance of the iterative cone beam CT (iCBCT) imaging mode of Varian linear accelerators and to explore its specific advantages in clinical application.Methods:The kV cone beam CT (CBCT) imaging systems of Halcyon 2.0, Edge, and VitalBeam linear accelerators from Tianjin Medical University Cancer Institute & Hospital were selected, among which Halcyon 2.0 and Edge were equipped with the iCBCT imaging mode. The Penta-Guide phantom was used to evaluate the registration accuracy of iCBCT imaging modes. The accuracy of treatment couch position was measured by a ruler. The image quality of the iCBCT and conventional CBCT modes of various imaging devices were analyzed using the CatPhan604 phantom. The imaging beam-on time and reconstruction time were measured to assess image acquisition efficiency. The uniformity, spatial resolution, contrast, contrast-to-noise ratio (CNR), image acquisition time and reconstruction time between two imaging modes were statistically analyzed by t-test. Results:The maximum deviations of image registration measurement results of the iCBCT mode for Halcyon 2.0 and Edge accelerators compared to the standard values were 0.7 mm and 0.6 mm, respectively. The treatment couch position error of all devices was less than 1 mm. The iCBCT images under head scanning protocol primarily improved the uniformity and CNR. Compared to conventional CBCT images, Halcyon iCBCT increased the uniformity and CNR by 2.50% ( P<0.001) and 78.85% ( P<0.001), respectively, while Edge increased them by 2.18% ( P<0.001) and 86.42% ( P<0.001), both superior to VitalBeam CBCT images. Under pelvis scanning protocols, iCBCT images primarily improved the CNR compared to conventional CBCT images. Halcyon and Edge iCBCT increased the CNR by 113.57% ( P<0.001) and 133.87% ( P<0.001), respectively, both superior to VitalBeam CBCT images. In terms of image acquisition efficiency, the average reconstruction times for Halcyon and Edge iCBCT images increased by 7.28 s and 15.53 s, respectively, and the total image acquisition time of Halcyon accelerator was the shortest. Conclusions:While ensuring the registration accuracy, iCBCT imaging mode can significantly improve the CNR of images and improve the uniformity of images under head scanning protocol. The Halcyon imaging system can enhance image acquisition efficiency.

Effective supervision of the clinical research management department can guarantee and improve the quality of the investigator initiated trials(IIT). The authors analyzed relevant clinical research regulations and literature and summarized the current situation of risk-based IIT project process quality management. On such basis, they determined the risk-based IIT project process quality management method in combination with the previous research of the research group.From 2021 to 2022, this method was used to implement process quality management for 353 IIT projects in Shanghai′s tertiary hospitals. More than 3 000 risk points were identified through centralized supervision, and then on-site supervision was carried out to correct the problems found. As proven by the results, the method could find existing problems in time and define the risk level of the project, and also formulate an individualized risk supervision plan accordingly, so as to effectively ensure the data reliability and scientific results. It is suggested that the clinical research management department implement risk based management for the whole process of IIT projects, increase funding and staffing, and implement hierarchical management for the projects by research types, so as to promote the sustainable development of IITs.

Background::The risk for chronic kidney disease (CKD) is influenced by genetic predisposition, sex, and lifestyle. Previous research indicates that coffee is a potentially protective factor in CKD. The current study aims to investigate whether sex disparity exists in the coffee–CKD association, and whether genetic risk of CKD or genetic polymorphisms of caffeine metabolism affect this association.Methods::A total of 359,906 participants from the UK Biobank who were enrolled between 2006 and 2010 were included in this prospective cohort study, which aimed to estimate the hazard ratios for coffee intake and incident CKD using a Cox proportional hazard model. Allele scores of CKD and caffeine metabolism were additionally adjusted for in a subsample with qualified genetic data ( n = 255,343). Analyses stratified by genetic predisposition, comorbidities, and sex hormones were performed. Tests based on Bayesian model averaging were conducted to ascertain the robustness of the results. Results::Coffee was inversely associated with CKD in a dose-dependent manner. The effects of coffee did not differ across different strata of genetic risk for CKD, but were more evident among slower genetically predicted caffeine metabolizers. Significant sex disparity was observed ( P value for interaction = 0.013), in that coffee drinking was only associated with the risk reduction of CKD in females. Subgroup analysis revealed that testosterone and sex hormone-binding globulin (SHBG), but not estradiol, modified the coffee–CKD association. Conclusions::In addition to the overall inverse coffee–CKD association that was observed in the general population, we could also establish that a sex disparity existed, in that females were more likely to experience the benefit of the association. Testosterone and SHBG may partly account for the sex disparity.

Copy number variations (CNVs), which can affect the role of long non-coding RNAs (lncRNAs), are important genetic changes seen in some malignant tumors. We analyzed lncRNAs with CNV to explore the relationship between lncRNAs and prognosis in bladder cancer (BLCA). Messenger RNA (mRNA) expression levels, DNA methylation, and DNA copy number data of 408 BLCA patients were subjected to integrative bioinformatics analysis. Cluster analysis was performed to obtain different subtypes and differently expressed lncRNAs and coding genes. Weighted gene co-expression network analysis (WGCNA) was performed to identify the co-expression gene and lncRNA modules. CNV-associated lncRNA data and their influence on cancer prognosis were assessed with Kaplan-Meier survival curve. Multi-omics integration analysis revealed five prognostic lncRNAs with CNV, namely

Objective:To assess possible risk factors and their respective levels in the whole process of investigator initiated trial(IIT)projects proposed in the proposal stage, for reference in formulation of risk management plans.Methods:Through literature analysis and research group discussions, the risk factors of IIT projects and risk level assessment criteria were preliminarily identified, and a consultation questionnaire was developed as a result. Delphi method was used to further optimize the risk factors and determine their risk levels. Data obtained from the consulfation were analysied by descriptive.Results:The recovery rates of two rounds of expert consultation were both 100%, and the degree of expert authority was 0.942. The survey finalized 38 risk factors, including extremely high risk, high risk, medium risk, low risk and very low risk factors of 17(44.7%), 15(39.5%), 3(7.9%), 2(5.3%) and 1(2.6%) respectively.Conclusions:This study determined a risk evaluation system of IIT projects in the proposal stage. This system can identify risks of IIT projects at an early stage, facilitating early intervention of problems existing in such projects, and minimize risks to the rights and safety of patients.

As one of the most effective and commonly used analgesic methods during labor and delivery,epidural analgesia has been widely accepted in terms of its safety.Neurological complications following childbirth,which are most related to pregnancy and childbirth factors rather than labor analgesia,has not been well studied or recognized in China.Therefore,there are some confusions and misunderstandings of reasons for these neurological complications,and,to a certain extent,have affected the clinical implementation of epidural labor analgesia.This review analyzed the etiology and prognosis of this problem in order to help the clinicians in identifying the risk factors and causes and also to improve clinical awareness,prevention,and management for these conditions.

Objective: To compare the clinical effects of two different skin preparation methods for infant craniocerebral surgery. Methods: Totally 120 infants who were going to receive craniocerebral surgery were divided into two groups by random number table, 60 cases in the observation group and 60 cases in the control group. The scalp of both groups was cleaned with moisturizing oil every day from 3 days before operation. On 1 day before operation, the observation group used electric shaver to shave off all hair on the head, and then rinsed with warm water. The control group was treated with skin preparation knife to shave all the hair under soap water lubrication and rinse with warm water. The skin injury rate, incision infection rate and pain score of the two groups were evaluated. Results: The incidence of skin injury and incision infection were 0 and 1.7% (1/60) in the observation group, 18.3% (11/60) and 13.3% (8/60) in the control group, respectively. There were significant differences between the two groups (χ²= 12.110, 5.886, all P < 0.01 or 0.05). The median score of pain in the observation group was 0 (Q₁:0, Q₃:0), while 1.5 (Q₁:1, Q₃:2) in the control group, and there were significant differences between the two groups (Z= 3.286, P < 0.01). Conclusion Electric shaver is superior to skin preparation knife in shaving hair of infants. It not only reduces the incidence of head skin injury, incision infection and pain in the process of skin preparation, but also reduces the incidence of incision infection after craniocerebral surgery in infants. It is worth popularizing.
