Objective:To investigate the clinical efficacy of robotic surgery via the bilateral axillo-breast approach（BABA） in lateral lymph node dissection for papillary thyroid carcinoma（PTC）. Methods:Clinicopathological records of 324 PTC patients receiving unilateral neck dissection in Tianjin Medical University Cancer Institute and Hospital from December 2020 to November 2024 were retrospectively analyzed. Of these patients, 108 underwent robotic surgery via BABA（robotic group）, while the remaining patients underwent conventional open surgery（open group）. The extent of lateral neck lymph node dissection included level Ⅱ, Ⅲ and Ⅳ. The differences in surgical indexes, postoperative complication rates and cosmetic outcomes of incisions were compared between two groups. Results:All study subjects completed the operation successfully, and there was no conversion in the robotic group. The average age of patients in the robotic group was lower than that in the open group, and the proportion of female patients was higher in the robotic group compared to the open group（P<0.05）. Patients in the robotic group had a greater number of dissected lymph nodes in level ⅡB and higher cosmetic scores（P<0.05）. There were no statistically significant differences between the two groups in the average dissection time of lateral cervical lymph nodes, the number of dissected lymph nodes and metastatic lymph nodes in level ⅡA, Ⅲ, and Ⅳ, average postoperative drainage volume, average postoperative hospital stay, and postoperative complication rates（P>0.05）. Conclusion:The application of robotic surgical system via BABA in lateral neck lymph node dissection for PTC is safe and feasible, with superior advantages in level ⅡB dissection and better postoperative cosmetic outcomes.

Congenital orofacial cleft, the most common birth defect in the maxillofacial region, exhibits a wide range of prognosis depending on the severity of deformity and underlying etiology. Non-syndromic congenital orofacial clefts typically present with milder deformities and more favorable treatment outcomes, whereas syndromic congenital orofacial clefts often manifest with concomitant organ abnormalities, which pose greater challenges for treatment and result in poorer prognosis. This consensus provides an elaborate classification system for varying degrees of orofacial clefts along with corresponding diagnostic and therapeutic guidelines. Results serve as a crucial resource for families to navigate prenatal screening results or make informed decisions regarding treatment options while also contributing significantly to preventing serious birth defects within the development of population.

OBJECTIVES: This study aimed to evaluate the therapeutic effect of 1% povidone-iodine mouthwash combined with scaling and root planing in patients with stage Ⅰ/Ⅱ class A/B periodontitis, and to provide a basis for the clinical application of povidone-iodine mouthwash. METHODS: Seventy-five subjects were included in this trial and randomly divided into three groups. After full-mouth ultrasonic supragingival cleansing, scaling and root planing, the placebo group was treated with sodium chloride injection (NaCl group), the control group was treated with compound chlorhexidine mouthwash (CHX group), and the experimental group was treated with 1% povidone-iodine mouthwash (PVP-I group), and rinsed their mouths for 1 week, respectively. Subjects were tested at 1, 4, and 12 weeks after dosing for clinical indicators, microbial composition of supragingival plaque, gingival crevicular fluid inflammatory marker levels, and patient-reported outcomes. RESULTS: Sixty-three subjects completed the follow-up. After treatment, the clinical indicators, microbial indicators, and inflammatory indicators were all significantly improved (P<0.05). Comparisons among the groups showed that one week after treatment, the bleeding index and plaque index of the CHX group and the PVP-I group were lower than those of the NaCl group, and the plaque index of the CHX group was lower than that of the PVP-I group (P<0.05). There were no statistically significant differences in the other clinical indicators among the groups (P>0.05). Twelve weeks after treatment, the Shannon index of the CHX group was lower than that of the NaCl group (P<0.05), and there were no statistically significant differences in the other microbial indicators among the groups (P>0.05). Twelve weeks after treatment, the interleukin-10 concentration of the CHX group was higher than that of the NaCl group (P<0.05), and there were no statistically significant differences in the other inflammatory indicators among the groups (P>0.05). The PVP-I group had the highest scores in terms of taste and oral odor. There was no obvious staining on the tooth surfaces and mucosa in all three groups. CONCLUSIONS 1% PVP-I mouthwash combined with scaling and root planing can effectively reduce gingival inflammation and dental plaque, improve clinical symptoms in the short term. While its efficacy is not significantly inferior to that of chlorhexidine, PVP-I mouthwash is more acceptable to patients than chlorhexidine.

Objective:To explore the views of adolescents with asthma on factors affecting disease self-management, so as to provide a basis for improving self-management of asthma children, and propose improvement suggestions.Methods:This study was a descriptive qualitative study. From February to June 2023, 10 to 17 year old children with asthma were recruited at the Asthma Clinic of the Children's Hospital affiliated to Capital Institute of Pediatrics through purposive sampling. One-on-one semi-structured interviews were conducted around self-management and its related factors, and the thematic analysis was used to analyse interview materials.Results:A total of 17 adolescents with asthma, aged (13.00±2.03) years, with a course of disease of (5.00±2.85) years, were included. The interview materials included two aspects, namely facilitators and barriers of self-management. The facilitators were coded into three themes and seven sub-themes, including the individual management awareness of children with asthma (sense of responsibility, compliance awareness), social support (parental care and compensation, teacher and classmate support, patient interaction), and health education (health guidance from doctors and nurses, school health propaganda). Barriers were encoded into three themes and six sub-themes, including disease cognition (demand competition, importance), social environment (interpersonal interaction, physical environment), and healthcare services (accessibility of medical services, school related medical resources) .Conclusions:The self-management of adolescents with asthma is affected by multiple factors. Individual management awareness, social support, and health education can promote self-management in children with asthma, while unfavorable factors in disease cognition, social environment, and healthcare services can hinder self-management in children with asthma. Medical and nursing staff should develop and implement empowerment plans for self-management of asthma children, by mobilizing multi-channel medical resources, providing multi-dimensional full process empowerment, and helping asthma children build a diverse interpersonal support network system, in order to promote effective health management transition for adolescents with asthma.

Objective:To explore the effectiveness and safety of programmed death 1(PD-1) inhibitory combined with chemotherapy as a neoadjuvant therapy for locally advanced resectable oral squamous cell carcinoma.Methods:This study was a randomized controlled phase Ⅱ trial. Patients recruited from Tianjin Medical University Cancer Institute and Hospital from July 2021 to February 2023 were randomly divided into two groups in a 1∶1 ratio: the experimental group (Toripalimab combined with albumin paclitaxel and cisplatin) and the control group (albumin paclitaxel and cisplatin); patients in both groups underwent three cycles of neoadjuvant therapy. After completion of neoadjuvant therapy, patients were evaluated and subsequent surgical treatment was performed. According to the completion of treatment, the analysis was conducted on both the full analysis set and the protocol set. The effectiveness and safety of treatments were evaluated. SPSS 20.0 software was used for statistical analysis.Results:A total of 41 cases with oral cancer were enrolled, including 26 males and 15 females, aged between 34 and 74 years old. There were 23 cases in the experimental group and 18 cases in the control group. A total of 23 cases completed neoadjuvant therapy and surgery according to the protocol. Experimental group and control group showed respectively the complete response rates of 1/19 and 0/17, the partial response rates of 13/19 and 8/17, the stage-down rates of 4/19 and 3/17, the pathologic complete response rate of 8/14 and 2/9, with no statistically significant differences in individual rates between two groups ( P>0.05). The major pathological response rate of 13/14 in experimental group was higher than that of 2/9 in control group ( P<0.05). The incidence of grade 3-4 adverse reactions related to treatment was low in both groups (4/23 vs. 3/18, χ 2=0.13, P=0.72), and the most common serious adverse reactions in the experimental group were granulocyte deficiency and electrolyte disorder. There were no adverse reactions that affected subsequent surgical treatment or caused death, and the safety and tolerability were good. The median follow-up time was 15 months, and the one-year disease-free survival rate of the experimental group was higher than that of control group (92.86% vs. 77.78%, χ 2=0.62, P=0.42), with a relative decrease of 87% in the risk of disease progression or death ( P=0.029). For patients with programmed death-ligand 1(PD-L1) protein expression combined positive score≥20, the experimental group showed higher major pathological response rate than control group (5/5 vs. 0/4, P=0.03). Conclusion:The neoadjuvant therapy of immunotherapy combined with chemotherapy can improve the pathological remission of oral squamous cell carcinoma and the long-term survival benefits and the prognosis of patients.

OBJECTIVE: To investigate the effects of melatonin (MT) on bone mass and serum inflammatory factors in rats received ovariectomy (OVX) and to investigate the effects of MT on the levels of inflammatory factors in culture medium and osteogenic ability of bone marrow mesenchymal stem cells (BMSCs) stimulated by lipopolysaccharide. METHODS: Fifteen 12-week-old Sprague Dawley (SD) rats were randomly divided into 3 groups. The rats in Sham group only received bilateral lateral abdominal incision and suture, the rats in OVX group received bilateral OVX, and the rats in OVX+MT group received 100 mg/(kg·d) MT oral intervention after bilateral OVX. After 8 weeks, the levels of serum inflammatory factors [interleukin-1β (IL-1β), IL-6, and tumor necrosis factor α (TNF-α)] were detected using ELISA assay. Besides, the distal femurs were detected by Micro-CT to observe changes in bone mass and microstructure, and quantitatively measured bone volume fraction, trabecular thickness, and trabecular number. The BMSCs were extracted from the femurs of three 3-week-old SD rats using whole bone marrow culture method and passaged. The 3rd-5th passage BMSCs were cultured with different concentrations of MT (0, 1, 10, 100, 1 000 µmol/L), and the cell viability was then detected using cell counting kit 8 (CCK-8) to select the optimal concentration of MT for subsequent experiments. Cells were devided into osteogenic induction group (group A) and osteogenic induction+1/5/10 μg/mL lipopolysaccharide group (group B-D). The levels of inflammatory factors (IL-1β, IL-6 and TNF-α) in cell culture medium were detected using ELISA assay after corresponding intervention. According to the results of CCK-8 method and ELISA detection, the cells were intervened with the most significant concentration of lipopolysaccharide for stimulating inflammation and the optimal concentration of MT with osteogenic induction, defining as group E, and the cell culture medium was collected to detect the levels of inflammatory factors by ELISA assay. After that, alkaline phosphatase (ALP) staining and alizarin red staining were performed respectively in groups A, D, and E, and the expression levels of osteogenic related genes [collagen type Ⅰ alpha 1 chain (Col1a1) and RUNX family transcription factor 2 (Runx2)] were also detected by real time fluorescence quantitative PCR (RT-qPCR). RESULTS: ELISA and Micro-CT assays showed that compared with Sham group, the bone mass of the rats in the OVX group significantly decreased, and the expression levels of serum inflammatory factors (IL-1β, IL-6, and TNF-α) in OVX group significantly increased (P<0.05). Significantly, the above indicators in OVX+MT group were all improved (P<0.05). Rat BMSCs were successfully extracted, and CCK-8 assay showed that 100 µmol/L was the maximum concentration of MT that did not cause a decrease in cell viability, and it was used in subsequent experiments. ELISA assays showed that compared with group A, the expression levels of inflammatory factors (IL-1β, IL-6, and TNF-α) in the cell culture medium of groups B-D were significantly increased after lipopolysaccharide stimulation (P<0.05), and in a concentration-dependent manner. Moreover, the expression levels of inflammatory factors in group D were significantly higher than those in groups B and C (P<0.05). After MT intervention, the expression levels of inflammatory factors in group E were significantly lower than those in group D (P<0.05). ALP staining, alizarin red staining, and RT-qPCR assays showed that compared with group A, the percentage of positive area of ALP and alizarin red and the relative mRNA expressions of Col1a1 and Runx2 in group D significantly decreased, while the above indicators in group E significantly improved after MT intervention (P<0.05). CONCLUSION MT may affect the bone mass of postmenopausal osteoporosis by reducing inflammation in rats; MT can reduce the inflammation of BMSCs stimulated by lipopolysaccharide and weaken its inhibition of osteogenic differentiation of BMSCs.

Objective The purpose of this study was to investigate the protective effect of dexmedetomidine(DEX)on pathological car-diomyocyte hypertrophy.Methods An in vitro cell population was established in neonatal rats.The rats were divided into six groups:control group(C)without serum for 24 h,model group(A)with angiotensin Ⅱ(Ang Ⅱ)for 24 h,dexmedetomidine group(AD)with Ang Ⅱ+DEX(5μmol/L)for 24 h,C'group with serum-free culture for 48 h,A'group with Ang Ⅱfor 24 h,and AD'group with DEX+Ang Ⅱfor 24 h.The morphological changes of cells were observed by immunofluorescence.The protein expressions of atrial natriuretic peptide(ANP),brain natriuretic peptide(BNP),and myosin heavy chain(β-MHC)were detected by western blot,and the cell activity was detected by CCK-8.Results Compared with group C,the size of cells in group A was larger,and that in group AD was even more significant.Simi-lar observations were found for hypertrophy related proteins.Compared with group C,the expression of ANP,BNP,and βMHC increased in group A,although the increase in AD group was more obvious.CCK-8 detection showed that compared with group C,the activity of group A decreased and that of group AD increased significantly.Compared with the C'group,the expression of hypertrophy-related pro-tein in the A'group was significantly increased,but the expression of ANP and BNP protein in the AD'group was significantly lower than that in the A'group.The differences were statistically significant(P<0.05).Conclusion Dexmedetomidine can alleviate the occur-rence of pathological hypertrophy through compensatory mechanisms similar to physiological myocardial hypertrophy,and may play a role in myocardial protection.

The biological samples of oral genetic diseases and rare diseases are extremely precious. Collecting and preserving these biological samples are helpful to elucidate the mechanisms and improve the level of diagnose and treatment of oral genetic diseases and rare diseases. The standardized construction of biobanks for oral genetic diseases and rare diseases is important for achieving these goals. At present, there is very little information on the construction of these biobanks, and the standards or suggestions for the classification and coding of biological samples from oral and maxillofacial sources, and this is not conducive to the standardization and information construction of biobanks for special oral diseases. This consensus summarizes the background, necessity, principles, and key points of constructing the biobank for oral genetic diseases and rare diseases. On the base of the group standard "Classification and Coding for Human Biomaterial" (GB/T 39768-2021) issued by the National Technical Committee for Standardization of Biological Samples, we suggest 76 new coding numbers for different of biological samples from oral and maxillofacial sources. We hope the consensus may promote the standardization, and smartization on the biobank construction as well as the overall research level of oral genetic diseases and rare diseases in China.
