Objective:To predict lymph node metastasis in patients preoperatively diagnosed with early-stage cervical cancer based on preoperative inflammatory and immune nutritional indicators,and to construct a nomo-gram prediction model,providing a basis and tool for preoperative diagnosis of lymph node metastasis in cervical cancer.Methods:A retrospective analysis was conducted on the clinical data of 307 patients preoperatively diag-nosed with early-stage cervical cancer who underwent surgical treatment at the Obstetrics and Gynecology De-partment of the Second Affiliated Hospital of Zhengzhou University from January 2018 to July 2023.R software was used to randomize the groups into a training set(n=231)and a validation set(n=76)in a 3∶1 ratio.Uni-variate and multivariate logistic regression analyses were employed to identify factors influencing lymph node me-tastasis in patients preoperatively diagnosed with early-stage cervical cancer.R software was used to establish a nomogram prediction model and draw receiver operating characteristic(ROC)curves and calibration curves for validation.Results:① The results of univariate logistic regression analysis showed that positive lymphovascular invasion,platelet-to-lymphocyte ratio(PLR)≥151.70,neutrophil-to-white blood cell ratio(NWR)≥0.65,plate-let-to-albumin ratio(PAR)≥ 4.94,preoperative systemic immune-inflammation index(SII)≥604.03,and sys-temic inflammatory response index(SIRI)≥ 1.05 were associated with lymph node metastasis(P＜0.05).②Multivariate logistic regression analysis found that positive lymphovascular invasion,NWR≥0.65,and PAR≥4.94 were independent risk factors for lymph node metastasis in patients preoperatively diagnosed with early-stage cervical cancer(OR＞1,P＜0.05).③ A nomogram was constructed to predict lymph node metastasis in patients preoperatively diagnosed with early-stage cervical cancer.The ROC curve shows an area under the train-ing set curve(AUC)of 0.821 and a validation set AUC of 0.858.The calibration curve shows an average abso-lute error of 0.024 for the training set and 0.059 for the validation set.Conclusions:The prediction model for lymph node metastasis in cervical cancer constructed using preoperative inflammatory and immune nutritional indi-cators such as NWR,PAR is helpful for gynecological oncologists to predict lymph node metastasis in cervical cancer patients before surgery.

Objective This study aimed to evaluate the clinical outcomes of immediate implantation of single maxil-lary central incisor and explore factors affecting post-implant bone volume.Methods Clinical data and imaging records from pre-surgery,the day of surgery,and 6 months post-surgery of 100 patients(100 implants)with non-salvageable maxillary central incisors who underwent immediate implantation were collected.Bone thickness at the cervical,middle,and apical regions of the implant's labial and palatal sides were measured immediately post-surgery and at 6 months,and bone volume changes were observed.A regression analysis model was used to assess predictive factors for labial and pal-atal bone plate thickness.Results At 6 months post-surgery,the labial bone thicknesses at the cervical,middle,and api-cal regions were 2.35,2.29,and 3.28 mm,respectively,and those of the palatal side were 0.00,2.40,and 6.05 mm,re-spectively.The cervical region had the highest alveolar crest collapse rates,with 32.87%on the labial side and 62.20%on the palatal side.The regression model indicated that factors influencing the thickness of bone at the cervical labial side of the implant included initial bone thickness,the implant center to adjacent tooth center angle,implant diameter,and the type of implant closure(P<0.05).The initial bone thickness on the palatal side was the sole predictor for bone thickness on the palatal side(P<0.05).Conclusion Immediate implantation of single maxillary central incisors yields effective clinical results.The thickness of new bone around the implant is influenced by multiple factors.A comprehensive consideration of these factors in the plan-ning of immediate implantation is necessary to achieve optimal therapeutic outcomes.

Objective To observe the effect of traditional Chinese medicine(TCM)syndrome differentiation treatment of insomnia on depressive symptoms and interleukin(IL)-6 level and tumor necrosis factor(TNF)-α level in serum.And then to discuss the effect of TCM syndrome differentiation treatment of insomnia on reducing the occurrence and development of depression.Methods Sixty patients with insomnia disorder in Hangzhou Hospital of Traditional Chinese Medicine from September 2020 to July 2022 were selected as research objects,and they were divided into intervention group and blank group 30 patients for each group,according to their treatment intention and they were treated with sleep hygiene education plus TCM syndrome differentiation treatment and sleep hygiene education alone respectively.The changes of sleep,depression,serum IL-6 level and TNF-α level were compared between two groups.Results After 2 weeks of intervention,the intervention group's Pittsburgh sleep quality index score,patient health questiomnare-9 score,TCM symptom score,and serum IL-6 and TNF-α level were all significantly reduced,and the difference was statistically significant(P＜0.05).Conclusion TCM syndrome differentiation treatment can effectively improve insomnia and depression,thus delaying the occurrence and development of depression,and is an effective method for early intervention of depression.

Objective:To discuss the effect of sialic acid-binding immunoglobulin-like lectin-15(Siglec15)derived from M2 tumor-associated macrophages(M2-TAMs)on promoting the malignant biological behavior of the esophageal squamous cell carcinoma(ESCC)through bioinformatics analysis,and to validate the findings through cell experiment.Methods:The Tumor Immune Estimation Resource(TIMER)online Database was used to analyze the expression differences and immune infiltration of Siglec15 in pan-cancer and adjacent normal tissues.Real-time fluorescence quantitative PCR(RT-qPCR)method was used to detect the expression levels of Siglec15 mRNA in M2-TAMs and ESCC EC109 and KYSE150 cells.Based on the non-contact co-culture of M2-TAMs and ESCC cells,the following groups were set up,such as EC109/KYSE150 group,EC109/KYSE150+si-NC group(transfected with si-NC sequence),and EC109/KYSE150+si-Siglec15 group(transfected with si-Siglec15#1 and si-Siglec15#2 sequences).CCK-8 method was used to detect the proliferation activities of the cells in various groups;wound healing assay was used to detect the wound healing rates of the cells in various groups;Transwell chamber assay was used to detect the numbers of migration and invasion cells in various groups;flow cytometry was used to detect the apoptotic rates of the cells in various groups.Results:The bioinformatics analysis results showed that compared with adjacent normal tissue,the expression levels of Siglec15 mRNA in pan-cancer tissues such as esophageal cancer,colon cancer,and head and neck squamous cell carcinoma tissues were increased(P＜0.05 or P＜0.01),and the expression level of Siglec15 mRNA in esophageal cancer tissue was significantly positively correlated with the infiltration of the macrophages(P＜0.05).Compared with the EC109 cells and KYSE150 cells,the expression level of Siglec15 mRNA in M2-TAMs was significantly increased(P＜0.01).There was no significant difference in the proliferation rate of the cells among EC109/KYSE150 group,EC109/KYSE150+si-NC group,and EC109/KYSE150+si-Siglec15 group(P＞0.05).Compared with EC109/KYSE150 group,after treated for 24 and 48 h,the wound healing rate of the cells in EC109/KYSE150+si-NC group was increased(P＜0.01),the numbers of migration and invasion cells were increased(P＜0.05),and the apoptotic rate was decreased(P＜0.01).Compared with EC109/KYSE150+si-NC group,the wound healing rates of the cells in EC109/KYSE150+si-Siglec15#1 group and EC109/KYSE150+si-Siglec15#2 group were decreased(P＜0.05),the numbers of migration and invasion cells were decreased(P＜0.05),and the apoptotic rates of the cells had no significant difference(P＞0.05).Conclusion:Siglec15 derived from M2-TAMs may be a key factor in promoting the migration and invasion of the ESCC cells.
