Objective:To develop a treatment-related quality of life scale for Chinese patients with multiple myeloma (MM) and to test its reliability and validity.Methods:The initial scale was constructed through a literature search, Delphi expert correspondence, and cognitive testing. This study conducted a preliminary survey of 379 patients with MM and a formal survey of 865 patients from the hematology departments of 155 hospitals nationwide from February 2024 to March 2024. The final scale was obtained after conducting item analysis and reliability and validity tests on the initial scale.Results:The constructed scale contains 36 items covering six domains: physiological, psychological, social, treatment side effects, general health, and others. In the preliminary survey, the Cronbach’s alpha coefficient of each item ranged from 0.597 to 0.939, and the test-retest reliability was 0.747 ( P<0.001). Exploratory factor analysis extracted eight common factors with a cumulative variance contribution of 60.058%. In the formal survey, the Cronbach’s alpha coefficient of each item ranged from 0.484 to 0.930, and the test-retest reliability was 0.835 ( P<0.001). Confirmatory factor analysis revealed a comparative fit index of 0.750, a root-mean-square error of approximation of 0.090, and a root-mean-square residual of 0.067. Conclusion:The treatment-related quality of life scale for Chinese patients with MM designed in this study exhibited good reliability and validity, reflecting the impact of treatment on the quality of life of patients. This scale can provide a reference to clinicians for assessing the disease status of patients.

The prefrontal cortex and hippocampus may support sequential working memory beyond episodic memory and spatial navigation. This stereoelectroencephalography (SEEG) study investigated how the dorsolateral prefrontal cortex (DLPFC) interacts with the hippocampus in the online processing of sequential information. Twenty patients with epilepsy (eight women, age 27.6 ± 8.2 years) completed a line ordering task with SEEG recordings over the DLPFC and the hippocampus. Participants showed longer thinking times and more recall errors when asked to arrange random lines clockwise (random trials) than to maintain ordered lines (ordered trials) before recalling the orientation of a particular line. First, the ordering-related increase in thinking time and recall error was associated with a transient theta power increase in the hippocampus and a sustained theta power increase in the DLPFC (3-10 Hz). In particular, the hippocampal theta power increase correlated with the memory precision of line orientation. Second, theta phase coherences between the DLPFC and hippocampus were enhanced for ordering, especially for more precisely memorized lines. Third, the theta band DLPFC → hippocampus influence was selectively enhanced for ordering, especially for more precisely memorized lines. This study suggests that theta oscillations may support DLPFC-hippocampal interactions in the online processing of sequential information.

Background::Carotid intima-media thickness (IMT) and diameter, stiffness, and wave reflections, are independent and important clinical biomarkers and risk predictors for cardiovascular diseases. The purpose of the present study was to establish nationwide reference values of carotid properties for healthy Chinese adults and to explore potential clinical determinants.Methods::A total of 3053 healthy Han Chinese adults (1922 women) aged 18-79 years were enrolled at 28 collaborating tertiary centers throughout China between April 2021 and July 2022. The real-time tracking of common carotid artery walls was achieved by the radio frequency (RF) ultrasound system. The IMT, diameter, compliance coefficient, β stiffness, local pulse wave velocity (PWV), local systolic blood pressure, augmented pressure (AP), and augmentation index (AIx) were then automatically measured and reported. Data were stratified by age groups and sex. The relationships between age and carotid property parameters were analyzed by Jonckheere-Terpstra test and simple linear regressions. The major clinical determinants of carotid properties were identified by Pearson’s correlation, multiple linear regression, and analyses of covariance.Results::All the parameters of carotid properties demonstrated significantly age-related trajectories. Women showed thinner IMT, smaller carotid diameter, larger AP, and AIx than men. The β stiffness and PWV were significantly higher in men than women before forties, but the differences reversed after that. The increase rate of carotid IMT (5.5 μm/year in women and 5.8 μm/year in men) and diameter (0.03 mm/year in both men and women) were similar between men and women. For the stiffness and wave reflections, women showed significantly larger age-related variations than men as demonstrated by steeper regression slopes (all P for age by sex interaction <0.05). The blood pressures, body mass index (BMI), and triglyceride levels were identified as major clinical determinants of carotid properties with adjustment of age and sex. Conclusions::The age- and sex-specific reference values of carotid properties measured by RF ultrasound for healthy Chinese adults were established. The blood pressures, BMI, and triglyceride levels should be considered for clinical application of corresponding reference values.

Objective:To investigate the effectiveness and feasibility of whole exome sequencing (WES), as a molecular diagnosis technique, for adult patients with genetic diseases.Methods:The present retrospective analysis included 445 adult patients (ages 18-80 years) with suspected genetic diseases who underwent whole exome sequencing (WES) from August 2021 to December 2022. The pathogenicity classification of each variant was assessed in accordance with the recommendations developed by the American Society of Medical Genetics and Genomics.Results:The overall positive rate of WES among adult patients with suspected genetic diseases was 28.08% (125/445). The highest positive rate was observed in the age group of 41-50 years (34.33%, 23/67). Among the diagnosed genetic diseases, those affecting the cardiovascular system (63.16%, 84/133), nervous system (18.05%, 24/133), and endocrine system (13.53%, 18/133) ranked as the top three. The most common genetic diseases identified through WES in adult patients were hypertrophic cardiomyopathy (18.80%, 25/133), dilated cardiomyopathy (16.54%, 22/133), Marfan syndrome (15.04%, 20/133), epilepsy (9.02%, 12/133), and familial hypercholesterolemia (4.51%, 6/133). The main causative genes identified included FBN1 (14.29%, 19/133), MYBPC3 (9.02%, 12/133), MYH7 (9.02%, 12/133), LDLR (3.76%, 5/133), TTN (3.76%, 5/133), and TNNI3 (3.01%, 4/133).Conclusion:Applying the WES technique in clinical practice can improve the diagnostic rate of adult genetic diseases, especially in adult patients with suspected genetic conditions involving the cardiovascular system, nervous system, and endocrine system.

【Objective】 To develop and implement a precise and efficient telephone recruitment strategy for apheresis platelet donors based on the information management of blood collection and supply process. 【Methods】 A telephone recruitment strategy based on the whole process information management of apheresis platelet donors (hereinafter referred to as telephone recruitment) was formulated From January 1, 2019, apheresis platelet donors in Hangzhou, registered in the intelligent blood donor recruitment system(hereinafter referred to as the recruitment system), were recruited by telephone calls or (and) SMS reminders to inform re-donation interval, key points of recruitment consultation, blood donation appointment time and other precautions. Response rate, pass rate and blood donation rate of donors before(in 2018) and after( in 2019) the implementation of telephone recruitment, as well as the above three rates during the COVID-19 epidemic in 2020 in Hangzhou were collected and analyzed by χ² test. 【Results】 The response rate, pass rate, and blood donation rate of apheresis platelet donors in Hangzhou before /after the implementation of telephone recruitment and during the COVID-19 epidemic were 28.52%(3 901/13 678)vs 30.52%(4 429/14 511)vs 39.36%(4 064/10 326), 73.80%(2 879/3 901)vs 77.83%(3 447/4 429)vs 78.20%(3 178/4 064)and 6.77%(2 879/42 553)vs 7.77%(3 447/44 366)vs 8.13%(3 178/39 077, respectively(P<0.05). In 2020, 85.94%(3 178/3 698) of apheresis donors were recruited by telephone(P<0.05). The proportion of apheresis donations successfully recruited by telephone in 2018 and 2019 accounted for 11.74% (2 879/24 519) and 12.48% (3 447/27 628), respectively(P<0.05), contributing 10.59% (4 030 U/38 040 U) and 11.38% (4 875 U/42 853 U) of units(P<0.05) that issued to the clinical. Due to the COVID-19 epidemic, the number of blood donors recruited by telephone and its proportion in 2020 decreased significantly as compared with those before the implementation of telephone recruitment (2019). 【Conclusion】 The telephone recruitment strategy based on the whole-process information management (system) of blood collection and supply can effectively improve the targeted recruitment of apheresis platelet donors and enhance its proportion of apheresis collection that issued to the clinical.
