Hu Lingling, Sun Yingjia, Jiang Peiling, Xie Zhijian
2025, 23 (3):  209-214.  doi: 10.19438/j.cjoms.2025.03.001
Abstract ( 5 )   PDF (871KB) ( 3 )  
The orthodontic-orthognathic treatment is presently the predominant approach to rectifying dentomaxillofacial deformities. Nevertheless, the extended duration of the treatment cycle and the intricacy of the surgical procedures pose significant challenges for patients situated in various locations and restrict the accessibility of superior medical resources. To mitigate these limitations, this study introduced a remote medicine model for dentomaxillofacial deformities, predicated on the "internet + medicine" paradigm, and delineated its standardized procedures and quality control framework. This model adhered to the "1+1+N" paradigm, where a remote medical center served as the nucleus, and a dentomaxillofacial deformity consultation e-cloud platform functioned as the interconnecting nexus. This arrangement facilitated the effective amalgamation of superior medical resources, thereby augmenting treatment efficacy and enhancing patient experience. Additionally, this study focused on the detailed construction of a multifunctional dentomaxillofacial deformity consultation e-cloud platform and comprehensive quality control framework. This approach provided a scientific and effective solution for strengthening remote medical quality supervision, promoting the rational allocation of medical resources, and improving the service level of primary hospitals.

Maidina Imam, Zhou Yuchuan, Muzafar Muhetar, Gong Zhongcheng
2025, 23 (3):  221-227.  doi: 10.19438/j.cjoms.2025.03.003
Abstract ( 8 )   PDF (1173KB) ( 4 )  
PURPOSE: To investigate the expression of Piezo1 in venous malformation(VM) tissues and human umbilical vein endothelial cells (HUVECs). METHODS: The wax samples of patients diagnosed with venous malformations were obtained, and the expression levels of antibodies Piezo1, TRPV4, P2X7, CD31 and α-SMA were detected by immunohistochemistry in the samples of venous malformations and normal veins. Overexpression of TIE2-L914F and TIE2-WT genes in HUVECs led to construction of venous malformation cell models and wild-type cell models, with HUVECs as the control group. The expression of mRNA and protein levels of Piezo1, TRPV4 and P2X7 in each group were detected by RT-qPCR, Western blot and enzyme-linked immunosorbent assay(ELISA). SPSS 27.0 software package was used for data analysis. RESULTS: Immunohistochemical results showed that Piezo1 expression was positive in both normal vein tissue and VM tissue, while TRPV4 and P2X7 expression were negative. Western blot results showed that there were significant differences in Piezo1 protein expression levels among the three groups, and the Piezo1 protein levels of the TIE2-L914F group were significantly down-regulated(P<0.01). There were no significant differences in the expression levels of TRPV4 and P2X7 proteins among the three groups(P>0.05). ELISA results showed that the expression of Piezo1 in the VM group was significantly lower than that in the normal cell group(P<0.0001), and the expression of TRPV4 in the three groups had no significant difference (P>0.05), and the expression of P2X7 in the three groups had no significant difference (P>0.05). RT-qPCR results showed that Piezo1 mRNA levels in TIE2-L914F group were significantly down-regulated compared with TIE2-WT and HUVEC group (P<0.001). CONCLUSIONS: The expression of Piezo1 in venous malformation tissues is lower than that in normal tissues, suggesting that Piezo1 is involved in the development and remodeling of blood vessels.

Expression, function and clinical significance of voltage-dependent anion channel 1 in oral squamous cell carcinoma
Xu Chenghui, Yao Yanli, Sun Shuyang
2025, 23 (3):  228-235.  doi: 10.19438/j.cjoms.2025.03.004
Abstract ( 6 )   PDF (1689KB) ( 3 )  
PURPOSE: This study aimed to investigate the expression level of voltage-dependent anion channel 1 (VDAC1) in oral squamous cell carcinoma (OSCC) and analyze its potential role in tumor progression as well as its clinical significance. METHODS: The expression level and prognostic relevance of VDAC1 in head and neck squamous cell carcinoma (HNSCC) were analyzed using UALCAN database. Genes associated with VDAC1 expression were identified using the database, and their expression levels and prognostic significance in HNSCC were analyzed. Immunohistochemical (IHC) staining was performed to evaluate VDAC1 expression in OSCC tissues. OSCC cells were treated with a VDAC1 inhibitor to observe its effects on cell proliferation and migration. GraphPad Prism 10.0 software package was used for data analysis. RESULTS: Analysis of the database revealed that VDAC1 was overexpressed in HNSCC tissues and was strongly associated with lymph node metastasis. High VDAC1 expression was correlated with significantly poorer overall survival and recurrence free survival in HNSCC patients. Additionally, VDAC1 expression was significantly correlated with several genes, including heat shock protein A4 (HSPA4), protein phosphatase 2 catalytic subunit alpha (PPP2CA), nucleophosmin 1 (NPM1), and cell division cycle protein 23(CDC23). These genes were also highly expressed in HNSCC and were strongly associated with poorer OS in patients. IHC analysis further confirmed that VDAC1 expression was markedly elevated in OSCC tissues compared to normal tissues. Inhibition of VDAC1 significantly suppressed the proliferation and migration of OSCC cells, highlighting its pivotal role in tumor progression. CONCLUSIONS: VDAC1 plays a critical role in the progression of OSCC. Its high expression is closely associated with tumor aggressiveness and poor prognosis, suggesting that VDAC1 may serve as both a prognostic biomarker and a potential therapeutic target for OSCC. This study further reveals that VDAC1 may regulate tumor progression through its interaction with genes such as HSPA4, PPP2CA, NPM1, and CDC23, providing important insights into the pathogenesis of OSCC and the basis for precision therapy.

Xue Pengxin, Sun Lulu, Sun Shuyang
2025, 23 (3):  236-243.  doi: 10.19438/j.cjoms.2025.03.005
Abstract ( 6 )   PDF (1301KB) ( 3 )  
PURPOSE: To investigate the differences in tumor microenvironment and molecular phenotype between human papillomavirus (HPV)-related (HPV+) and non-HPV-related (HPV-) head and neck cancers (HNC). METHODS: Genomic, transcriptomic, and proteomic sequencing data for HNC were obtained from the TCGA public database via open-access platforms such as cbioportal. The patients were categorized into HPV+ and HPV- group based on HPV infection status. First, the CIBERSORTx cell-type deconvolution algorithm was applied to transcriptomic data to estimate differences in cellular composition between HPV+ and HPV- HNC. Subsequently, genomic, transcriptomic, and proteomic data were analyzed to identify genes with significantly increased mutation frequencies, enriched pathways, and upregulated proteins in HPV+ HNC compared to HPV- HNC. RESULTS: Significant differences were observed between HPV+ and HPV- HNC. ①Cellular composition: HPV+ tumors exhibited significantly higher infiltration of B cells, CD4+ T cells, and dendritic cells. ②Multi-omics alterations: genes such as CCM2L, CBFA2T2, and NECAB3 showed higher mutation frequencies in HPV+ tumors. The neuroactive ligand-receptor interaction pathway was significantly enriched in HPV+ tumors, proteins such as CLDN7 and SYK displayed higher expression levels in HPV+ tumors. ③FADS1 and ELF3 potentially participated in or regulated the phenotypic evolution of HPV+ HNC. FADS1 was a potential interacting protein of HPV16 E2, while ELF3 was a transcription factor specifically expressed in HPV+ epithelial tissues. Both genes exhibited a significant positive correlation with the gene set associated with the neuroactive ligand-receptor interaction pathway. CONCLUSIONS: Compared to HPV- HNC, the distribution of microenvironmental cell subtypes and potential regulatory elements in HPV+ HNC is significantly different, characterized by a higher proportion of immune cells and enrichment in pathways related to neural signaling and immune response.

Liu Yu, Miao Keyan, Hu Yuhua, Wu Yue, Feng Guanying, Xia Ronghui, Yang Xi
2025, 23 (3):  244-252.  doi: 10.19438/j.cjoms.2025.03.006
Abstract ( 6 )   PDF (1196KB) ( 4 )  
PURPOSE: This study aimed to investigate the correlation between p53 staining patterns and TP53 mutation status in oral squamous cell carcinoma(OSCC), as well as their associations with clinicopathologic features. METHODS: Tissue samples from 60 OSCC patients were analyzed using whole-exome sequencing and immunohistochemical staining with p53 antibodies (MX008 and YN01766m). TP53 mutation status and p53 staining patterns (Null, overexpression [OE], and wild type[WT]) were compared with clinicopathologic features. Correlations between p53 staining patterns and TP53 mutation status were evaluated. GraphPad Prism 8 software package was used for data analysis. RESULTS: TP53 was the most frequently mutated gene in OSCC, with mutations significantly associated with higher pTNM stage, DOI, and PNI, and correlated with poor prognosis in public datasets. The Null pattern exhibited the highest sensitivity in detecting loss-of-function (LOF) mutations, while OE pattern predicted gain-of-function (GOF) mutations and showed clinical value for patient stratification. Both antibodies had similar performance in detecting and matching TP53 mutation status. CONCLUSION: TP53 is the most common mutation in OSCC,and its mutation is associated with adverse clinicopathological features and poor prognosis. p53 staining is sensitive to LOF mutations and is expected to be a biomarker of GOF mutations, providing a cost-effective method for patient stratification and targeted therapy.

Abstract ( 5 )   PDF (911KB) ( 3 )  
PURPOSE: To investigate the value of contrast-enhanced ultrasonography (CEUS) in the differential diagnosis of cervical lymph node tuberculosis and oral and maxillofacial squamous cell carcinoma with cervical lymph node metastases. METHODS: The ultrasonographic data of 38 patients(55 abnormal lymph nodes) with enlarged cervical lymph nodes who presented to First Affiliated Hospital of Xinjiang Medical University and underwent neck dissection were categorized into tuberculosis group(n=27) and metastatic(n=28) group according to the pathological results, and the imaging characteristics of conventional imaging and CEUS were compared. SPSS 25.0 software package was used for data analysis. RESULTS: The differences between the tuberculosis and metastasis group in terms of boundaries, morphology, lymphatic portal structures, internal echoes, and the presence of liquefied and calcified areas were not statistically significant(P>0.05). A comparison of the pattern and type of perfusion between the two groups showed a statistically significant difference(P<0.05). Centrifugal perfusion was predominant in the tuberculosis group, whereas afferent perfusion was predominant in the metastatic group. Perfusion type was predominantly type Ⅱ in the tuberculosis group and type Ⅲ in the metastatic group. CONCLUSIONS: Compared with conventional ultrasonography, CEUS has a higher diagnostic value in identifying cervical lymph node tuberculosis and metastatic cervical lymph nodes of OSCC in clinical practice.

2025, 23 (3):  271-275.  doi: 10.19438/j.cjoms.2025.03.010
Abstract ( 4 )   PDF (779KB) ( 4 )  
PURPOSE: To investigate the prevalence of temporomandibular disorders (TMD) in young men who participated in the physical examination of Qingzhou conscription, and to observe the effects of two different treatments for TMD. METHODS: The oral medical history information of 690 male youth who participated in the conscription physical examination for enlisted citizens in Qingzhou city in the autumn of 2021 and the spring of 2022 was collected. The temporomandibular joint functions were examined, and the prevalence of TMD and the incidence rates of various symptoms were calculated. Among them, totally 85 patients with TMD were selected as the research subjects and randomly divided into group A(n=42) and group B(n=43). Group A was treated with oral and maxillofacial system functional exercises, while group B was treated with full-arch anatomical occlusal splints. The therapeutic effects of TMD were evaluated after 3 months of treatment, and the recurrence of patients was observed after 12 months. The data were statistically analyzed using SPSS 20.0 software package. RESULTS: A total of 120 TMD patients were identified in 690 youths with a prevalence rate of 17.39%, with 61 cases (18.05%) among 338 young men surveyed in the fall of 2021 and 59 cases (16.76%) among 352 young men surveyed in the spring of 2022. There was no significant difference in TMD prevalence between the two investigations (P>0.05). In addition, among the 690 youths, the incidence of clicking was the highest (15.65%), followed by mandibular dyskinesia (7.25%) and pain (1.30%). A few of the 120 TMD patients had a past medical history, mainly manifested as mandibular dyskinesia and clicking. After 3 months, the symptoms of TMD patients in group A were significantly improved after functional exercise, and there was no recurrence after 12 months. Among the 43 TMD patients in group B, 23 cases were completely cured, 9 cases were improved, but 4 cases recurred after 12 months. CONCLUSIONS: There is a high prevalence rate of TMD among young male recruits, most of them are mild and mainly characterized by clicking. After conservative treatment through functional exercises, patients with TMD can be cured and meet the enlistment standards, and thus should be retained.

Yue Li, Wang Shan, Ma Jinfeng, Wang Ling
2025, 23 (3):  276-283.  doi: 10.19438/j.cjoms.2025.03.011
Abstract ( 5 )   PDF (926KB) ( 3 )  
PURPOSE: To investigate the effect of autogenous tooth bone powder combined with concentrated growth factors (CGF) in the repair of distal bone defects in the second molar after impacted mandibular third molar extraction. METHODS: A total of 25 patients with distal bone defect of second molar after bilateral mandibular impacted third molar extraction were selected in the First Affiliated Hospital of Xinjiang Medical University from June 2023 to June 2024. A bilateral controlled experiment was conducted, with one side as the experimental group (n=25) and the other side as the control group (n=25). The experimental group received treatment with autogenous tooth powder combined with CGF, while the control group received CGF treatment alone. Postoperative probing depth(PD), clinical attachment loss(CAL), osseous defect depth(ODD), bone mineral density, operative time, Postoperative Symptom Severity Scale(PoSSe), adjacent tooth hypersensitivity, postoperative infection, and numbness of lower lip were compared between the two groups. SPSS 26.0 software package was used for data analysis. RESULTS: At 3 and 6 months postoperatively, the PD and CAL in both groups were significantly lower than those at 2 weeks postoperatively (P<0.001); the reduction rates of PD and CAL in the experimental group were significantly higher than those in the control group at 6 months postoperatively (P<0.001); the reduction amount of ODD in the experimental group was significantly higher than that in the control group at 3 and 6 months postoperatively (P<0.001). There were significant differences in bone density between the experimental group and the control group at 3 and 6 months postoperatively. The operation time in the experimental group was longer than that in the control group, with a statistically significant difference. The postoperative PoSSe scores for speech, appearance, and pain showed significant different between the two groups (P<0.05). The incidence of distal tooth sensitivity of the second molar in the control group was significantly higher than that in the experimental group(P<0.05). CONCLUSIONS: Autogenous tooth bone powder combined with CGF can effectively promote the recovery of distal bone defects in the second molar, improve the periodontal condition of the distal second molar, and has high clinical application value. CGF alone can also improve the depth of distal bone defects in the second molar, but the recovery of the height of the bone defect is not obvious, and the long-term effect is not good.

2025, 23 (3):  290-296.  doi: 10.19438/j.cjoms.2025.03.013
Abstract ( 6 )   PDF (965KB) ( 5 )  
PURPOSE: To systematically evaluate the return-to-work emotions and experiences of head and neck cancer survivors and help in developing the individualized return-to-work interventions. METHODS: A systematic search was conducted in CNKI, Wanfang database, VIP, China Biomedical Literature Service System, PubMed, Embase, Web of Science, MEDLINE, Cochrane Library, CINAHL, and APA PsycInfo databases for qualitative studies on the experiences of head and neck cancer survivors returning to work. The search period covered from the establishment of the databases to December 2023. The quality of the literature was evaluated by two investigators using The Joanna Briggs Institute Critical Appraisal Tool for Qualitative Research(2016) in Australia. The results were integrated using a pooled integration approach. RESULTS: Twelve studies were included, of which 65 were distilled and synthesized into three themes and 11 subthemes, including the importance and inadequacy of symptom distress affecting head and neck cancer survivors' work status and career progression, the coping measures by head and neck cancer survivors in order to adapt to work, and the importance and inadequacy of social support for head and neck cancer survivors to return to work. CONCLUSIONS: The survival of head and neck cancer patients is hampered by multiple factors when they return to work. Attention should be paid to the symptomatic burden and psychological state of head and neck cancer survivors. Symptom management should be strengthened, social support systems should be reinforced, and targeted intervention and support strategies should be formulated to promote the early return of head and neck cancer survivors to the workplace.

Abstract ( 5 )   PDF (765KB) ( 3 )  
Buccal fat padBFP) is an irregular mass of adipose tissue located within the deep facial recesses, with rich blood supply and encapsulated structure, which can isolate mesenchymal stem cells with multidirectional differentiation ability. The pedicled buccal fat pad flap is easy to prepare and has a high survival rate, and has been widely used in the repair of soft and hard tissue defects in the oral and maxillofacial region. The osteogenic ability of buccal fat pad derived mesenchymal stem cells has been demonstrated in vitro and has been used in clinical trials to repair jaw defects in recent years. In plastic surgery, the potential of both pedicled and free buccal fat pad flaps for improving facial contours continues to be explored. However, research on the long-term benefits for patients and the differences between these flaps and other pedicled skin flaps is limited. This review summarized the current advancements in the anatomy and some clinical applications of the buccal fat pad.

Fan Hao, Dong Xiang
2025, 23 (3):  310-312.  doi: 10.19438/j.cjoms.2025.03.017
Abstract ( 3 )   PDF (737KB) ( 3 )  
Acute pulmonary edema after intraoperative topical administration of epinephrine is a rare but serious complication. This paper reported a case of acute pulmonary edema in a 17-month-old girl who was treated with epinephrine during cleft palate repair. The patient was healthy before operation and had no history of allergies or major diseases. During operation, the patient developed increased heart rate, decreased blood pressure, and decreased oxygen saturation after local use of hemostatic water containing adrenaline. Subsequently, a large amount of pink foam-like secretions were sucked through the tracheal catheter and diagnosed as acute pulmonary edema. The patient 's condition was rapidly stabilized and the operation was successfully completed through the replacement of tracheal catheter and dehydration treatment by lung suction. The vital signs of the children were stable after operation.
