Objective To explore the safety and effects of alpha-lipoic acid (ALA) in patients with ischemic heart failure (IHF). Methods A randomized, double-blind, placebo-controlled trial was designed (ClinicalTrial.gov registration number NCT03491969). From January 2019 to January 2023, 300 patients with IHF were enrolled in four medical centers in China, and were randomly assigned at a 1∶1 ratio to receive ALA (600 mg daily) or placebo on top of standard care for 24 months. The primary outcome was the composite outcome of hospitalization for heart failure (HF) or all-cause mortality events. The second outcome included non-fatal myocardial infarction (MI), non-fatal stroke, changes of left ventricular ejection fraction (LVEF) and 6-minute walking distance (6MWD) from baseline to 24 months after randomization. Results Finally, 138 patients of the ALA group and 139 patients of the placebo group attained the primary outcome. Hospitalization for HF or all-cause mortality events occurred in 32 patients (23.2%) of the ALA group and in 40 patients (28.8%) of the placebo group (HR=0.753, 95%CI 0.473-1.198, P=0.231; Figure 1A-1C). The absolute risk reduction (ARR) was 5.6%, the relative risk reduction (RRR) associated with ALA therapy was approximately 19.4% compared to placebo, corresponding to a number needed to treat (NNT) of 18 patients to prevent one event. In the secondary outcome analysis, the composite outcome of the major adverse cardiovascular events (MACE) including the hospitalization for HF, all-cause mortality events, non-fatal MI or non-fatal stroke occurred in 35 patients (25.4%) in the ALA group and 47 patients (33.8%) in the placebo group (HR=0.685, 95%CI 0.442-1.062, P=0.091; Figure 1D). Moreover, greater improvement in LVEF (β=3.20, 95%CI 1.14-5.23, P=0.002) and 6MWD (β=31.7, 95%CI 8.3-54.7, P=0.008) from baseline to 24 months after randomization were observed in the ALA group as compared to the placebo group. There were no differences in adverse events between the study groups. Conclusions These results show potential long-term beneficial effects of adding ALA to IHF patients. ALA could significantly improve LVEF and 6MWD compared to the placebo group in IHF patients.

Objective:We genetically modified our non-replicating vaccinia virus NTV to improve its immunogenicity.Methods:We constructed NTV-modified strain NTV-ΔF1L-C7L by homologous recombination of vaccinia virus based on CRISPR-Cas9 technology by inserting the C7L gene while deleting the F1L gene. The recombinant virus NTV-ΔF1L-C7L was then immunized with 10 7 PFU in BALB/c mice, and the levels of humoral and cellular immunity induced by NTV-ΔF1L-C7L were detected by ELISA and ELISpot method, respectively, and the levels of neutralizing antibodies were determined by the phage-reduced neutralization assay. Results:The PCR and western- blot identification proved that the F1L gene of the constructed NTV-modified strain NTV-ΔF1L-C7L was missing, while the C7L gene was inserted back in the region, and the C7L gene could be expressed normally, indicating that the recombinant virus was constructed correctly. After immunization of mice with NTV-ΔF1L-C7L, ELISA result showed that the recombinant virus NTV-ΔF1L-C7L induced a higher level of IgG antibody than NTV; ELISpot result also showed that the recombinant virus was able to induce a higher level of IFN-γ; and the result of plaque reduction neutralization test showed that the recombinant virus was able to induce a higher level of IFN-γ antibody than that of NTV.Conclusions:We correctly constructed the NTV gene-modified strain NTV-ΔF1L-C7L, which induced stronger humoral and cellular immunity compared with NTV, and provided reference data for the research and development of replacement products for smallpox or monkeypox vaccines.

Preliminary exploration of using ultrasound to quantitatively evaluate the development of epiphyseal cartilage and analyze its correlation with bone age, based on the ultrasound findings of the long bone joint end. A study was conducted on adolescents studying at a sports school in Jining from March to June 2023. Age, height and other information were recorded. Bone age assessment by X ray were performed within 1 week with an endocrinologist interpreted the bone age using the Greulich-Pyle atlas. Two sonographers scanned a total of 7 sites in the hand, wrist and knee joint of the non-dominant side (including the dorsal side of the third metacarpal head, the ulnar styloid process, the radial styloid process, the medial and the lateral femoral epicondyle, dorsal tibia, and medial tibial condyle). The ultrasonic epiphyseal cartilage thickness (UECT) was measured and its correlation with bone age was analyzed. Intraclass correlation coefficient (ICC) was used to evaluate the reliability and repeatability of UECT measurement. A total of 141 adolescents were included, with 80 males and 61 females. The average age was 13 (12-14) years old. The average bone age was 15(13-17) years in males and 16 (14-17) years in females. The proportion of the males and females whose bone age was 1 year older than chronological age was 60% and 67%, respectively, and the height of the males was significantly higher than that of the females( Ultrasound can observe and describe the developmental change of long bone, and UECT has potential value in quantitative evaluation of bone maturity.

To research on area ossification ratio (AOR), a novel parameter for quantitatively assessing adolescent bone age by conventional ultrasonography, and evaluate the correlation between AOR and radiographic bone age. The study selected healthy adolescents from a middle school in Shandong Province in June 2023. Ultrasonic images were collected from five anatomical sites (the styloid process of the ulna, the styloid process of the radius, the lateral epicondyle of the femur, the medial condyle of the tibia, and the posterior median sagittal plane of the tibia). The second ossification center and epiphyseal area on these 2D ultrasound images were delineated to calculate AOR. This ratio was then compared with radiographic bone age measured by Greulich-Pyle (GP) atlas. Inter- and intra-observer consistency was evaluated using intraclass correlation coefficient (ICC) and the Bland-Altman method. A total of 179 healthy adolescents (109 males and 70 females) were included. For both genders, AOR of each site exhibited a significant to high correlation with radiological bone age ( The sum of AORs in adolescents is highly correlated with radiographic bone age, and the measurement method shows high repeatability. The AOR is a reliable parameter for the ultrasonic quantitative assessment of bone age in adolescents.

To evaluate the correlation between ultrasound ossification ratio(OR) and exercise intensity among adolescents. This cross-sectional study used stratified sampling to select adolescents aged 11-15 years from a sports school and some ordinary middle schools in Shandong Province in June 2023. The participants were divided into two groups: competitive sports group (high exercise intensity), and general sports group (moderate exercise intensity), based on their exercise intensity. Ultrasound images of long bones from nine body regions (including 3 upper limb bones and 6 lower limb bones) were collected for both groups. Two sonographers interpreted the images and calculated the ultrasound OR values (the ratio of ossification center length to epiphyseal length on the standard ultrasound section). The intraclass correlation coefficient (ICC) was used to assess the consistency of image interpretation between the observers. Differences in ultrasound OR values between the two groups were compared, and multivariate Logistic regression analysis was performed to assess the correlation between ultrasound OR values and exercise intensity. A total of 252 adolescents who met the inclusion and exclusion criteria were included, with 154 in the competitive sports group (97 males and 57 females) and 98 in the general sports group (52 males and 46 females). The median height and average daily exercise duration were significantly higher in the competitive sports group than in the general sports group (all The medial femoral ultrasound OR value was correlated with exercise intensity among adolescents. This indicator may serve as an objective imaging parameter for assessing whether adolescent exercise meets recommended standards.
