Objective This study compared organ doses and effective doses in typical adult patients during dental CBCT examinations using a head-and-neck anthropomorphic phantom and a whole-body phantom. It aimed to determine an appropriate method for evaluating effective dose in dental CBCT. Methods A domestically manufactured dental CBCT unit was used to scan an adult male anthropomorphic phantom under simulated clinical conditions. Thermoluminescent dosimeters were placed on organs and tissues of a whole-body anthropomorphic phantom. Organ equivalent doses were measured, and effective doses were calculated using two approaches: one based on all organ doses from the whole-body phantom, and the other based only on head-and-neck organ doses. Entrance surface air kerma (K_a,e) was also measured at the lens of the eye, thyroid, thymus, and gonads. Results The effective dose estimated with the whole-body phantom was 382.03 μSv. The effective dose estimated with the head-and-neck phantom was 354.03 μSv. The radiation dose to head-and-neck organs and tissues accounted for 92.7% of the total effective dose. The highest K_a,e values were found in the parotid glands, followed by the lens of the eye. Conclusion During dental CBCT scanning, the contribution of organ below the head and neck to the total effective dose is limited. To simplify dose assessment procedures, the effective dose for the patient can be evaluated using only a head-and-neck phantom.

Objective:To explore the current status and influencing factors of quality of life in patients with thyroid-associated ophthalmopathy (TAO) .Methods:From January to July 2024, convenience sampling was used to select TAO patients of the Department of Ophthalmology of Peking University Third Hospital as research subjects. The patients were surveyed using the General Information Questionnaire, Graves' Ophthalmopathy Quality of Life Questionnaire (GO-QOL), Negative Physical Self Scale-Appearance (NPSS-A), Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS), and Perceived Social Support Scale (PSSS). Spearman correlation analysis was used to explore the correlation between GO-QOL scores and NPSS-A, SAS, SDS, and PSSS scores. Multiple linear regression was used to analyze the factors influencing the quality of life of TAO patients.Results:A total of 234 questionnaires were distributed, and 203 valid questionnaires were collected, with a valid response rate of 86.75%. The GO-QOL visual function and social function dimensions scores of 203 TAO patients were [78.57 (50.00, 100.00) ] and [43.75 (18.75, 62.50) ], respectively. Multiple linear regression analysis showed that age, eye movement disorders, eyelid retraction, and disease grading, were the influencing factors of the visual function dimension of GO-QOL ( P<0.05). Age, social support, and body image were the influencing factors on the social function dimension of GO-QOL ( P<0.05) . Conclusions:The quality of life of TAO patients is poor. Healthcare professionals should develop coping strategies based on factors affecting different dimensions of quality of life, so as to improve patients' quality of life.

OBJECTIVE To evaluate the cost-effectiveness of ivabradine in the treatment of chronic heart failure （CHF） in the context of “Quadruple Therapy” from the perspective of the health system. METHODS Based on real-world cohort data， the Markov model was constructed according to the natural progression of CHF， with a cycle time of 3 months， a study timeframe of 20 years， and a discount rate of 5%. Using quality-adjusted life year （QALY） and incremental cost-effectiveness ratios （ICER） as the output indexes， the cost-utility analysis was used to evaluate the cost-effectiveness of ivabradine in combination with the “Quadruple Therapy” regimen， compared with the “Quadruple Therapy” regimen for the treatment of CHF， and the robustness of the results of the base analysis was verified by univariate sensitivity analysis and probabilistic sensitivity analysis. RESULTS The results of the base analysis showed that the ICER of ivabradine combined with the “Quadruple Therapy” regimen was 165 065.54 yuan/QALY， compared with the “Quadruple Therapy” regimen， which was lower than the willingness-to-pay （WTP） threshold （257 094 yuan/QALY） based on 3 times of China’s gross domestic product （GDP） per capita in 2022. The results of the univariate sensitivity analysis showed that the discount rate had the greatest impact on the robustness of the model. The probabilistic sensitivity analysis showed that the probability that the ivabradine combined with the “Quadruple Therapy” regimen was cost-effective under the WTP threshold in this study was 59.50%. CONCLUSIONS When using 3 times China’s 2022 GDP per capita （257 094 yuan/ QALY） as the WTP threshold， the combination of ivabradine and the “Quadruple Therapy” regimen for treating CHF is cost- effective.

Human genetic resources are an indispensable part of national natural science and technology resources,as well as an important strategic resource for safeguarding national security,public health,and social public interests.To promote the effective protection and rational utilization of human genetic resources,as well as improve and optimize the local human genetic resources management system in China,this paper summarized the current situation of administrative approval and supervision of national human genetic resources from 2004 to 2021 by sorting out the national human genetic resources management policies and regulations.Furthermore,the current situation and progress of local human genetic resources management in China were understood from three aspects,including development planning and programs of human genetic resources,administrative licensing and penalties,and the construction of management expert committees.The main problems of local human genetic resources management in China were discussed and analyzed,such as unclear supervision,difficulty in supervision and inspection,and capacity for services.Based on the causes of the problems and the local management work,specific countermeasures and suggestions were put forward from the perspective of clarifying the regulatory policies and procedures for human genetic resources,improving the supervision and inspection mechanisms,and improving the management and service capabilities.

Objective:To investigate outcomes and safety of doxycycline-moxifloxacin sequential regimen in the treatment of Mycoplasma genitalium urethritis/cervicitis. Methods:From June 2019 to December 2020, patients with Mycoplasma genitalium urethritis/cervicitis confirmed by nucleic acid amplification testing were successively recruited at Department of Sexually Transmitted Diseases, Hospital of Dermatology, Chinese Academy of Medical Sciences, and received sequential therapy with oral doxycycline for 7 days followed by oral moxifloxacin for 7 days. Clinical and/or etiological assessment was conducted 2 to 3 weeks after the end of treatment. Fisher′s exact test was used to analyze factors influencing the treatment outcome. Results:Totally, 36 eligible subjects were enrolled, including 30 males and 6 females. Among them, 18 (50%) patients completed post-treatment etiological assessment, which showed that 12 achieved microbiological cure, and treatment failures occurred in 6; another 18 patients achieved clinical cure. The overall response rate to doxycycline-moxifloacin sequential therapy was 83.3% (30/36, 95% confidence interval[ CI]: 70.5%, 96.1%) . The treatment outcome showed no significant association with the patients′ age, gender, marital status, number of sexual partners in the past 1 month, history of sexually transmitted diseases, history of antibiotic use in the past 1 month, or co-infections (all P > 0.05) . Conclusion:The efficacy of doxycycline-moxifloacin sequential regimen is limited in the treatment of Mycoplasma genitalium infections in Nanjing area, and clinicians should be alerted to the possibility of treatment failure in clinical practice.

Psoriasis is characterized by abnormal proliferation of keratinocytes, as well as infiltration of immune cells into the dermis and epidermis, causing itchy, scaly and erythematous plaques of skin. The understanding of this chronic inflammatory skin disease remains unclear and all available treatments have their limitations currently. Here, we showed that IMMH002, a novel orally active S1P modulator, desensitized peripheral pathogenic lymphocytes to egress signal from secondary lymphoid organs and thymus. Using different psoriasis animal models, we demonstrated that IMMH002 could significantly relieve skin damage as revealed by PASI score and pathological injure evaluation. Mechanistically, IMMH002 regulated CD3 T lymphocytes re-distribution by inducing lymphocytes' homing, thus decreased T lymphocytes allocation in the peripheral blood and skin but increased in the thymus. Our results suggest that the novel S1P agonist, IMMH002, exert extraordinary capacity to rapidly modulate T lymphocytes distribution, representing a promising drug candidate for psoriasis treatment.
