Objective:To investigate the attention level of oral medicine residents in standardized training (referred to as residency training) to oral aesthetic information and its influencing factors.Methods:This study was a cross-sectional study, which included 262 residents undergoing standardized training at Hospital of Stomatology, Wuhan University in January 2020. Among them, there were 73 males and 189 females, with an age range of 23-33 (26±2) years. A questionnaire survey method was used, and the questionnaire included the basic characteristics of the subjects (gender, grade, major, identity, and having training experience in prosthodontic base or not) as well as their attention to oral aesthetic information (facial proportions, facial midline, smile line, facial contour, E-line, nasolabial angle, tooth shape and contour, and tooth proportions). Differences in the attention to oral aesthetic information among residents with different basic characteristics were compared, and a multivariable logistic regression was used to identify the influencing factors.Results:Among the 262 oral medicine residents, 256 (97.7%) believed that it was necessary to pay attention to oral aesthetic information. The differences in attention to facial proportions between residents of different genders and between those with and without training experience in the prosthodontic base were statistically significant (both P<0.05). The results of the multivariate logistic regression showed that male residents were less likely to pay attention to facial proportions compared with female residents ( OR=0.45, 95% CI: 0.23-0.88). Compared with residents specializing in orthodontics, non-orthodontic residents were less likely to pay attention to the E-line ( OR=0.14-0.27, 95% CI: 0.04-0.68) and nasolabial angle ( OR=0.14-0.31, 95% CI: 0.04-0.81). Residents who were graduate students with integrated four certificates were more likely to pay attention to the E-line compared with industry-based personnel ( OR=1.88, 95% CI: 1.01-3.49). Residents without training experience in the prosthodontic base were less likely to pay attention to the facial proportion ( OR=0.44, 95% CI: 0.20-0.97) and tooth shape and contour ( OR=0.33, 95% CI: 0.11-0.98) compared with those with such training experience in prosthodontic base. Conclusions:Oral medicine residents have a high level of attention to oral aesthetic information. Gender, major, identity, and having training experience in the prosthodontic base or not are factors that influence their attention to oral aesthetic information.

Injury biomechanics is an interdisciplinary field that studies the biomechanical responses and injury mechanisms of the human body under external loads.The goal is to provide scientific foundations for the prevention,diagnosis,and treatment of human injuries.This field is widely applied in clinical medicine,sports science,rehabilitation engineering,traffic safety,aerospace,and other domains.In this review,the research progress in injury biomechanics in the year 2023 is summarized,focusing on in-depth analysis of injury mechanisms,innovations in injury prediction and protective countermeasure,and the latest applications of injury diagnosis and rehabilitation technologies.By systematically reviewing the research advancements,this review aims to offer new directions and ideas to the continued development of injury biomechanics and promote interdisciplinary collaboration and technological innovation.

Gardenia jasminoides Ellis,a commonly used traditional Chinese medicine,is widely distributed in tropical and sub-tropical regions of our country.Gardenia jasminoides Ellis is of high medicinal value since it contains many kinds of chemical constituents,such as iridoids,monoterpenoids,diterpenes,triterpenoids,organic acid esters,and flavonoids.Gardenia jasminoides Ellis has the functions of liver and gallbladder protection,anti-inflammation and analgestic,blood pressure reduc-tion,lipid regulation,anti-depression,blood sugar decrease,and nerve protection.In this paper,the research progress of the chemical constituents and pharmacological action of Gardenia jasminoides Ellis at home and abroad in recent years is reviewed,so as to provide a reference for the further development and utilization of Gardenia jasminoides Ellis in the future.

Paeonia Radix Alba is the dried root of Paeonia lactiflora Pall.in the ranunculus family,which is mainly produced in Zhejiang(Hang Paeony),Anhui(Hao Paeony)and Sichuan(Chuan Paeony).It has the effects of calming liver,relieving pain,nourishing blood,regulating menstrual period,collecting Yin,and preventing perspiration.Similar to Paeonia Radix Alba,Paeonia Radix Rubra is the dried root of Paeonia lactiflora Pall.or Paeonia veitchii Lynch.in the ranunculus family.Although the chemical constituents are similar,the efficacy and clinical application of the two herbal medicines are obviously different owing to their various processing methods and techniques.Modern studies have shown that Paeonia Radix Alba is rich in multiple chemical constituents,mainly including monoterpenoids and their glycosides,triterpenoids and their glycosides,volatile oils,flavonoids,and polyphenols,and has a wide range of pharmacological effects such as analgesia,anti-inflammation,anti-depression,liver protection,anti-tumor,and anti-hyperglycemia.This paper reviews the progress of research on effective constituents of Paeonia Radix Alba and their pharmacological effects to provide references for the comprehensive development and utilization of Paeonia Radix Alba.

Objective To investigate the correlation between NRAMP1 gene polymorphisms and susceptibility to tuberculosis ( TB) in Tibetan people in Qinghai. Methods A case-control study was con-ducted in this study, involving 99 Tibetan patients with TB and 89 healthy Tibetans. The single nucleotide polymorphisms of NRAMP1 gene at rs17235409 and rs3731865 sites were detected by using TaqMan probe method. Gene cloning and sequencing typing were performed to analyze the single nucleotide polymorphisms of NRAMP1 gene at the rs17235416 site. SPASS20. 0 software was used to statistically analyze the correla-tion between NRAMP1 gene polymorphisms and susceptibility to TB in Tibetan people. Results No signifi-cant difference in the genotype frequencies of rs3731865 and rs17235409 was found between the two groups (χ2=0. 852, P=0. 356;χ2=0. 279, P=0. 597). The genotype frequencies of TGTG/TGTG and TGTG/del+del/del at the rs17235416 site were 70. 7% ( 70/99 ) and 29. 3% ( 29/99 ) in patients with TB and 86. 5% (77/89) and 13. 5% (12/89) in healthy subjects. There were significant differences in the geno-type frequencies of TGTG/TGTG and TGTG/del+del/del between the two groups (χ2=6. 870, P=0. 009). The genotypes of TGTG/del and del/del at rs17235416 were risk factors for TB ( OR=0. 376; 95%CI:0. 178-1. 794 as compared with the TGTG/TGTG genotype in Tibetan people in Qinghai. Conclusion This study suggested that the NRAMP1 gene polymorphisms at rs3731865 and rs1723409 sites had no correlation with the susceptibility to TB in Tibetans in Qinghai. However, the NRAMP1 gene polymorphisms at rs17235416 site were correlated with the susceptibility to TB. The TGTG/del alleles at the rs17235416 site might be the risk factors for tuberculosis in Tibetans in Qinghai.
