Behavioral economics offers an innovative theoretical and practical framework for HIV/AIDS prevention by elucidating the irrational tendencies in individual decision-making. This review explores core behavioral economics concepts and their applications in HIV/AIDS prevention, including how salience bias, present bias, and loss aversion influence high-risk populations′ behaviors. It also synthesizes empirical evidence on the effectiveness of nudge-based interventions in enhancing public health strategies, increasing HIV testing uptake, and improving treatment adherence.Additionally, the paper addresses key challenges in the field, such as interdisciplinary collaboration, cost-effectiveness analyses of economic incentives, and ethical and cultural considerations in implementation. Future research should further integrate sociocultural contexts specific to China to localize behavioral economics applications, refine intervention strategies, and optimize resource allocation. Such efforts will advance progress toward the global goal of ending the HIV epidemic by 2030.

Objective:To analyze the genetic stability of two recombinant rotaviruses (rLLR/NSP3 NLuc) and (rLLR/NSP3 CoV2/RBD) that are inserted and express exogenous genes for continuous passage and proliferation on MA104 cells.Methods:After measuring the titers of two recombinant rotavirus strains, they were transferred to the P2 generation according to MOI0.01. Subsequently, the previous generation of virus lysate was diluted and activated at 1∶100, and MA104 cells were continuously infected for 18 generations (P20). The virus titers of the P1, P5, P10, P15, and P20 generation of cell lysate were measured using indirect immunofluorescence, and RT-PCR identification and dsRNA PAGE silver staining were performed. The luciferase activity of rLLR/NSP3-NLUc was also detected.Results:No inserted fragment loss was found in the recombinant rotavirus rLLR/NSP3 NLuc within 20 generations, with recombinant virus titers ranging from 3.85~5.16 × 10 6 FFU/ml, with strong luciferase signals in each generation. The recombinant rotavirus rLLR/NSP3 CoV2/RBD showed loss of inserted fragments in the 6th generation, with infectivity titers ranging from 2.6 to 3.36 in the first 5 generations of the recombinant virus × 10 6 FFU/ml. Conclusions:The recombinant rotavirus with 582 bp NLuc inserted at the end of the NSP3 gene has good genetic stability, while the recombinant rotavirus with 885 bp RBD inserted at the end of the NSP3 gene was only stable in the first 5 generations, indicating that foreign genes can be inserted at the end of the NSP3 gene of the recombinant rotavirus, and the insert can express, but its stability requires more in-depth research.

Objective:To explore the method of obtaining the key parameters of the average value articulator in healthy people based on mandibular movement trajectory data, with a view to providing a reference for the clinical application of the average value articulator.Methods:One hundred healthy volunteers (42 males and 58 females) with individual normal occlusion, aged 18-55 years old, who met the inclusion criteria were recruited from Beijing, and their mandibular movement trajectory data were collected. The left and right sagittal condylar inclination(SCI) and transversal condylar inclination(TCI) were obtained from the values of the articulator parameters which were generated in the mandibular movement analysis system.The SCI and TCI were grouped by gender and calculated separately for the two groups and the overall sample; the gender differences in the two parameters and the differences between the mean values of the two parameters and the average value articulator empirical values (35° for SCI and 15° for TCI) for the overall sample were compared.Results:The differences between SCI (35.8°±7.4°) and TCI [11.2° (11.3°)] in males and the corresponding parameters [35.6°±8.3° and 10.8° (9.5°), respectively] in females were not statistically significant ( t=0.10, P=0.922; Z=-0.60, P=0.552); the overall sample SCI (35.7°±7.9°) did not differ statistically from the average value articulator empirical value ( t=1.23, P=0.221), and the overall sample TCI [10.9° (10.3°)] was significantly smaller than the average value articulator empirical value ( W=5 825.00, P<0.001). Conclusions:The mandibular movement trajectory data of 100 adults with individual normal occlusion in this study shows that the gender factor does not affect the setting of the key parameters of the average value articulator, the SCI of the average value articulator empirical values is appropriate, and the TCI has the possibility of being on the large side. In the clinical use of the articulator to assist in the design of restorations, the parameter values should be rationally adjusted according to the actual situation of the patient′s dentition and mandibular movement.

Menthol is the main component of mint volatile oil and a monoterpenoid organic compound. This article systematically summarizes the pharmacological effects， present development and application status of menthol. It is found that menthol can protect the central nervous system through acting on the transient receptor potential （TRP） channel subfamily M member 8， 5-hydroxytryptamine system， γ -aminobutyric acid system， etc. Menthol can regulate body temperature through temperature adjustment， relieving heat stress， and other means. It can play an anti-inflammatory role by regulating the production and release of inflammatory mediators such as prostaglandin E2 and leukotriene B4， and exert anti-inflammatory effects through cellular immune effect mediated by TRP channel. It can play analgesic role by activating classic pain perception targets and enhancing inhibitory synaptic transmission. It can promote transdermal absorption by destroying the stratum corneum. It can exert anti-tumor effects by regulating tumor cell proliferation， apoptosis， and adhesion pathways. Menthol can be used as a medicinal excipient for correcting the taste of drugs； it can also serve as an active ingredient and play an important pharmacological role in the treatment of disease， with potential development value.

Objective:To develop a pretest probability model of obstructive coronary artery disease with machine learning based on multi-site Chinese population data.Methods:Chinese regiStry in early deTection and Risk strAtificaTion of coronary plaques (C-Strat) study is a prospective multi-center cohort study, in which consecutive patients with suspected obstructive coronary artery disease and ≥64 detector row coronary computed tomography angioplasty (CCTA) evaluation were included. Data from the patients were randomly split into a training set (70%) and a test set (30%). More than 50% of coronary artery stenosis by CCTA was defined as positive outcome. A boosted ensemble algorithm (XGBoost), 10-fold cross-validation and Bayesian optimization were used to establish a new prediction model-CARDIACS(pretest probability model from Chinese registry in eARly Detection and rIsk stratificAtion of Coronary plaques Study), and a logistic regression was used to establish a model-LOGISTIC in training set. The test set was used for validation and comparison among CARDIACS, LOGISTIC, UDFM (updated Diamond-Forrester Model) and DFCASS(Diamond-Forrester and CASS).Results:The study population included 29 455 patients with age of (57.0±9.7) years and 44.8% women, of whom 19.1% (5 622/29 455) had obstructive coronary artery disease. For CARDIACS, the age, the reason for visit and the body mass index (BMI) were the most important predictive variables. In the independent test set, the area under the curve (AUC) of CARDIACS was 0.72 (95% CI 0.70-0.73), which was significantly superior to that of LOGISTIC (AUC 0.69, 95% CI 0.68-0.71, P=0.015), UDFM (AUC 0.64, 95% CI 0.62-0.65, P<0.001) and DFCASS (AUC 0.66, 95% CI 0.64-0.67, P<0.001), respectively. Conclusion:Based on Chinese population, the study developed a new pretest probability model--CARDIACS, which was superior to the traditional models. CARDIACS is expected to assist in the clinical decision-making for patients with stable chest pain.

Objective: Evidence supports the efficacy of coronary computed tomography angiography (CCTA)-based risk scores in cardiovascular risk stratification of patients with suspected coronary artery disease (CAD). We aimed to compare two CCTAbased risk score algorithms, Leiden and Confirm scores, in patients with diabetes mellitus (DM) and suspected CAD. Materials and Methods: This single-center prospective cohort study consecutively included 1241 DM patients (54.1% male, 60.2 ± 10.4 years) referred for CCTA for suspected CAD in 2015–2017. Leiden and Confirm scores were calculated and stratified as < 5 (reference), 5–20, and > 20 for Leiden and < 14.3 (reference), 14.3–19.5, and > 19.5 for Confirm. Major adverse cardiovascular events (MACE) were defined as the composite outcomes of cardiovascular death, nonfatal myocardial infarction (MI), stroke, and unstable angina requiring hospitalization. The Cox model and Kaplan–Meier method were used to evaluate the effect size of the risk scores on MACE. The area under the curve (AUC) at the median follow-up time was also compared between score algorithms. Results: During a median follow-up of 31 months (interquartile range, 27.6–37.3 months), 131 of MACE were recorded, including 17 cardiovascular deaths, 28 nonfatal MIs, 64 unstable anginas requiring hospitalization, and 22 strokes. An incremental incidence of MACE was observed in both Leiden and Confirm scores, with an increase in the scores (log-rank p < 0.001). In the multivariable analysis, compared with Leiden score < 5, the hazard ratios for Leiden scores of 5–20 and > 20 were 2.37 (95% confidence interval [CI]: 1.53–3.69; p < 0.001) and 4.39 (95% CI: 2.40–8.01; p < 0.001), respectively, while the Confirm score did not demonstrate a statistically significant association with the risk of MACE. The Leiden score showed a greater AUC of 0.840 compared to 0.777 for the Confirm score (p < 0.001). Conclusion CCTA-based risk score algorithms could be used as reliable cardiovascular risk predictors in patients with DM and suspected CAD, among which the Leiden score outperformed the Confirm score in predicting MACE.

Patients with end-stage liver disease (ESLD) are often accompanied by various complications such as sarcopenia and cachexia including lipopenia, and it was believed in the past that such status was associated with malnutrition, while recent studies have shown that myostatin (MSTN) is associated with the progression of ESLD. MSTN can lead to sarcopenia and cachexia by affecting the metabolism of glucose, fat, and protein and the number of myocytes, and it can be used as a screening indicator for hepatocellular carcinoma (HCC) and an indicator for disease progression. Intervention via the MSTN pathway might be an effective method for controlling sarcopenia and cachexia in patients with ESLD, and MSTN may be an effective indicator for predicting the progression of liver cirrhosis to HCC.

OBJECTIVE: To analyze the genotype and phenotype of a sibpair with partial deletion of SATB2 gene caused by 2q33.1 microdeletion. METHODS: Both children have featured mental retardation and development delay, and were subjected to karyotyping, single nucleotide microarray (SNP array) and real-time fluorescence quantitative PCR analysis. Karyotyping and SNP Array analysis were also carried out on their parents to verify the origin of mutation. RESULTS: Both sibs had a normal karyotype. SNP array showed that sib 1 had arr[hg19]2q33.1(200 192 328 - 200 197 269)×1 (4.9 kb), 2q35 (218 105 663 - 218 816 675)×3 (711 kb), while sib 2 had arr[hg19]2q33.1(200 192 328 - 200 197 269)×1 (4.9 kb), 2q35 (218 105 663-218 810 908)×3 (705.2 kb). The deletion has partially overlapped with that of 2q33.1 microdeletion syndrome and involved part of the SATB2 gene. The result of real-time fluorescence quantitative PCR assay was consistent with that of SNP assay. The duplication has originated from their father and has not been associated with any disease phenotypen. CONCLUSION Both sibs have carried partial deletion of SATB2 gene and had similar clinical phenotypes. Haploinsufficiency of such gene probably underlies the clinical manifestations in both patients.
