Objective To investigate the association of digit ratio with single nucleotide polymorphism(SNP)at three loci(rs17576,rs3918249,rs9509)of matrix metallopeptidase 9(MMP-9)gene.Methods A total of 804 Ningxia Han youths(399 males and 405 females)were used as the study subjects.A digital camera was used to take frontal photographs of the hands,and image analysis software was used to mark the anatomical points and measure the lengths of each finger of both hands(2D,3D,4D,5D);Multiplexed PCR was used to detect the three polymorphic sites of the MMP-9 gene,SPSS 25.0 and R Studio software were used for data analysis and plotting.Results The 2D/3D(P＜0.05)and 2D/4D(left,P＜0.01,right,P＜0.05)of both hands,2D/5D(P＜0.01),3D/5D,4D/5D(P＜0.05)of the right hand,and 3D/4D(P＜0.05)of the left hand in female youths of Ningxia Han were significantly higher than those in males,Differences in genotypes and allele frequencies at all 3 loci of the MMP-9 gene were not statistically significant between genders(P＞0.05).Right hand 2D/4D was significantly associated with genotypes at the rs17576 and rs3918249 loci in male youths(P＜0.05).Conclusion MMP-9 gene SNPs(rs17576 and rs3918249)may be associated with the formation of 2D/4D of Ningxia Han male youths.

[Objective]To clarify the botanical origin of the exotic herb Poluode in Bencao Shiyi.[Methods]By consulting ancient,modern,domestic and foreign literature,the botanical origin of Poluode was demonstrated from the aspects of drug name,transmission route and origin distribution,plant morphological characteristics and medical efficacy.[Results]The names of Poluode and Uyghur medicine Baladu both originate from the Sanskrit word"bhallātaka",which is the Sanskrit name for Semecarpus anacardium L.f.(S.anacardium).S.anacardium and mainly distributed in India,which coincides with the origin of Poluode,and their morphological characteristics are consistent,with similar medical efficacy.[Conclusion]The botanical origin of Poluode is S.anacardium,and it is also one of the plant sources of Baladu,a Uyghur medicine.Clarifying the Chinese herbs in Bencao Shiyi and bringing back the lost Chinese herbs from history is not only inheritance and promotion of the"Zhejiang school of materia medica"masterpiece Bencao Shiyi,but also promotes the"sinicization"of foreign excellent medicinal resources and advances the high-quality development of traditional Chinese medicine.

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.

Oropharyngeal squamous cell carcinoma(OPSCC)is a malignant tumor originating from the squamous epithelium of the oro-pharyngeal mucosa,accounting for more than 90％of oropharyngeal malignancies.In recent years,human papillomavirus(HPV)infec-tion has become one of the primary etiological factors of oropharyngeal squamous carcinoma.The incidence of HPV-associated oropharyn-geal squamous carcinoma has been rising annually,with a noticeable trend toward younger populations,posing a significant threat to hu-man health.Due to the distinct biological behavior and clinical characteristics of HPV-associated oropharyngeal squamous carcinoma com-pared to its non-HPV-related counterpart,the diagnostic and treatment strategies for oropharyngeal squamous carcinoma have undergone substantial changes.Prevention and screening for oropharyngeal squamous carcinoma are of critical importance.The diagnostic and treat-ment process involves multi-disciplinary collaboration,including oral and maxillofacial surgery,otolaryngology,head and neck surgery,oncology,radiology and pathology.Based on evidence from clinical practice,a comprehensive,integrated diagnostic and therapeutic ap-proach has been established,centered around the concept of"prevention,screening,diagnosis,treatment,and rehabilitation",covering the entire patient lifecycle and providing a valuable reference for clinical practice.

Oral squamous cell carcinoma(OSCC)is a malignant lesion originating from the oral mucosal squamous epithelium,account-ing for over 80％of oral and maxillofacial malignancies.Key etiological factors include tobacco,alcohol abuse,and betel quid chewing.In China,its incidence has shown an overall upward trend,posing a significant threat to public health.OSCC exhibits high local invasive-ness,making early diagnosis critical for improving prognosis.Its clinical management requires close multidisciplinary collaboration among oral and maxillofacial surgery,head and neck surgery,radiation oncology,medical oncology,reconstructive surgery,radiology,patholo-gy,and nutritional support teams.Given the increasing disease burden of OSCC and rapid development of multidisciplinary collaborative models,an expert panel has formulated this integrated management consensus based on evidence-based medicine and extensive deliber-ation.Centered on the'Prevention-Screening-Diagnosis-Treatment-Rehabilitation'framework,the consensus provides comprehensive guidance for the entire disease course of OSCC patients,aiming to standardize clinical practice.

Objective To review the factors affecting the occurrence of incontinence dermatitis in adults and severe patients,and provide clinical theoretical guidance for clinical nurses to reduce the incidence of incontinence dermatitis.Methods The literatures on the influencing factors of incontinence-associated dermatitis in adult patients with intensive care were searched in PubMed,Web of science,CINAHL,Embase,Cochrane Library,CNKI,Wanfang,Vip and SinoMed.The search period was from the establishment of the database to December 31th,2023(March 31,2025 updated).Results A total of 19 literatures were included,and the influencing factors of IAD mainly included 5 aspects:incontinence type,disease status,medication use,risk assessment and other factors.Conclusion There are many factors affecting the occurrence of incontinence-associated dermatitis in adult patients with intensive care,and nurses should implement diversified skin intervention strategies to reduce the incidence of IAD in adult patients with intensive care.

Objective:To analyze and confirm the ambiguous results of HLA-DRB1 genotyping in one case.Methods:HLA genotyping was performed on a sample of hematopoietic stem cell donor using Illumina MiSeq-based next-generation sequencing(NGS).The ambiguous results of HLA-DRB1 locus were further analyzed and confirmed through PacBio SMRT third-generation sequencing.Results:The Illumina MiSeq-based NGS typing results suggested the presence of a new HLA-DRB1*11 allele(DRB1*11:NEW,12:01)in the specimen,with a mismatch of G＞A located in the 40th residue of exon 1 compared with the nearest allele DRB1*11:01:01:03.However,due to the long sequence of intron 1,this observed mutation site was so far away from the near heterozygous sites that no reads could cover this gap.Therefore,it was impossible to determine which consensus the mutation site was located in,and the NGS-based genotyping results were obtained from the random allocation by the software,which was ambiguous and unreliable.In order to confirm the results,the long-read third generation sequencing technology based on PacBio was applied to genotype the DRB1 locus.The results showed that the DRB1 typing was HLA-DRB1*11:01,12:10.E1-40A was actually located in the allele HLA-DRB1*12:XX,which was exactly matched with HLA-DRB1*12:10.Conclusion:For some new alleles suggested by NGS,especially the ambiguous ones that are far away from other heterozygous sites,it is necessary to analyze and confirm them by other methods such as the third-generation long-read sequencing technology to obtain reliable results.

In recent decades,the incidence of human papillomavirus(HPV)-associated oropharyngeal squamous cell carcinoma(OPSCC)has shown a marked increase.Significant changes have also occurred in the OPSCC diagnosis and treatment paradigm.Deter-mining HPV status prior to treatment is now essential,and radiotherapy/chemotherapy,immunotherapy,and minimally invasive surgical techniques have progressively emerged as key modalities for managing OPSCC.However,alongside these paradigm shifts,a comprehen-sive technical consensus guiding the entire diagnostic and therapeutic process for OPSCC patients is currently lacking.Given China's large population base and the rising incidence of OPSCC,an expert panel convened to develop a clinical technical consensus on OPSCC diagno-sis and management tailored to China's specific context.This consensus aims to further enhance and standardize understanding of OPSCC management techniques among relevant healthcare professionals.
