Objective:To investigate the intervention effect of binary coping strategy based on systemic interaction model on the postoperative survival quality of patients with oral cancer.Methods:A total of 99 patients with oral cancer admitted to the Department of Oral and Maxillofacial Surgery of a tertiary hospital from Jun 2021 to Jun 2022 was selected.They were randomly divided into the control group(50 cases)and the observation group(49 cases)with random number table method.The control group received routine nursing for oral cancer.On this basis,the observation group also received the binary coping strategy based on the systemic interaction model.The scores of UW-QOL quality of life scale and binary coping scale were compared between the two groups before surgery,at the 3rd and 9th weeks after surgery.Results:The UW-QOL scores of both groups at the 3rd and 9th weeks after surgery were lower than those at admission,and the UW-QOL score in the control group was lower than that in the observation group(P＜0.05).At the 3rd week after surgery,the score of coping with the partner in the observation group was higher than that in the control group(P＜0.05).At the 9th week after surgery,the total score,negative coping,stress communication,coping together,and supportive coping scores in the observation group were higher than those in the control group(P＜0.05).Repeated measures analysis of variance showed that there was an interaction between time and group for the total score of binary coping scale(P＜0.05).And there was a significant main effect of time and group on the total score of binary coping scale(P＜0.05).Conclusions:The quality of life of patients with oral cancer is poor.The binary coping strategy based on the systemic interaction model can improve the quality of life of patients,enhance the intimacy of patients with their partners,and contribute to the disease recovery of patients with oral cancer.

Objective:To evaluate the impact of self-crosslinked hyaluronic acid (SCH) gel on endometrium recovery after artificial abortion.Methods:A multicenter, prospective randomized controlled trial was conducted across 18 hospitals from December 2021 to February 2023, involving 382 women who underwent artificial abortion. Participants were randomly allocated to receive either treatment with SCH gel (SCH group) or no treatment (control group) in a 1∶1 ratio. The primary outcome was endometrium thickness in 14 to 18 days after the first postoperative menstruation. Secondary outcomes included changes in menstrual volume during the first postoperative menstruation, menstruation resumption within 6 postoperative weeks, time to menstruation resumption, duration of the first postoperative menstruation, and incidence of dysmenorrhea.Results:Baseline characteristics of participants were comparable between the two groups (all P>0.05), with 95.3% (182/191) in SCH group and 92.7% (177/191) in the control group completed the study. The postoperative endometrial thickness in SCH group was significantly greater than that in the control group [(9.78±3.15) vs (8.95±2.32) mm; P=0.005]. SCH group also had significantly fewer participants with reduced menstrual volume [23 cases (12.6%, 23/182) vs 31 cases (17.5%, 31/177); P=0.038]. Although SCH group experienced less dysmenorrhea during the first postoperative menstrual period, this difference was not statistically significant [28.5% (51/179) vs 37.1% (65/175); P=0.083]. Outcomes were similar between SCH group and the control group regarding the proportion of participants who resumed menstruation within 6 weeks postoperatively, time to menstruation resumption, and duration of the first postoperative menstruation ( P=0.792, 0.485, and 0.254, respectively). No serious adverse events were observed during the study period, and no adverse events were attributed to SCH gel treatment. Conclusion:The application of SCH gel after artificial abortion is safe and might aid in the recovery of the endometrium.

Objective:To observe multiple locus variable-number tandem repeat analysis (MLVA) typing of Brucella isolated from Himalayan marmot in Qinghai-Tibet Plateau of Qinghai Province, and to explore the relationship between the strains and strains previous isolated from Qinghai Province. Methods:Blood samples of Himalayan marmot were collected in Qinghai-Tibet Plateau of Qinghai Province from March 2019 to October 2020. Pathogens were isolated and cultured from Brucella antibody positive samples identified by using the rose bengal test (RBT). Conventional biological methods and molecular biological methods (BCSP31-PCR and AMOS-PCR) were used for strain identification. At the same time, MLVA method was used to genotype the isolated strains, and cluster analysis was used to analyze the genetic relationships between the strains based on the genotype of 70 Brucella isolated from different hosts in Qinghai Province. Results:A total of 1 466 blood samples of Himalayan marmot were collected from Qinghai-Tibet Plateau. Two strains of Brucella were isolated and cultured from 64 RBT-positive samples, named QH2013054 and QH2013062, respectively. They were identified as Brucella ovis biotype Ⅲ by conventional and molecular biological methods. The MLVA genotyping results showed that QH2013054 and QH2013062 were different at the Bru16 locus, indicating different MLVA genotypes. Cluster analysis showed that strain QH2013054 had the same MLVA genotype as 7 strains, among which 6 strains were from 3 farmers and 3 sheep from the same family in Gonghe County, and 1 strain was from a farmer in Menyuan Hui Autonomous County. The strain QH2013062 had the same MLVA genotype as 4 strains, including 3 strains from 3 farmers in Menyuan Hui Autonomous County and 1 strain from a farmer in Tu Autonomous County of Huzhu. Conclusions:The strains of Brucella isolated from Himalayan marmot in Qinghai-Tibet Plateau of Qinghai Province have the same MLVA genotype as some strains of Brucella isolated from humans and sheep in Qinghai Province. It is speculated that the host humans, sheep and Himalayan marmot in Qinghai-Tibet Plateau may have a common source of infection.

Objective To analyze the failure patterns and prognostic factors of radical surgery in patients with T1-4N0-1M0 thoracic esophageal squamous cell carcinoma (TESCC),and the implications for the target area design of postoperative therapy.Methods We retrospectively analyzed 1 191 patients with TESCC who underwent radical surgery at our institution.The failure patterns,the prognostic factors,as well as the effects of lesion locations and N stage on the failure patterns were analyzed.Results The thoracic-region recurrence rate and the distant metastasis rate was 31.7％ and 16.4％ in all patients.The multivariate analysis showed that the lesion locations,the degree of inflammatory adhesion,T staging,N staging and the rate of lymph nodes metastasis were independent factors affecting the regional recurrence (P ＜ 0.05).Gender,tumor differentiation and the rate of lymph nodes metastasis were independent factors affecting distant metastasis (P ＜ 0.05).The intrathoracic lymph nodes recurrence rate of upper/middle TESCC was significantly higher than that of the lower TESCC (x2 =6.179,P =0.046),while the abdomen lymph nodes recurrence rate of the lower was significantly higher than that of upper/middle TESCC (x2 =15.853,P ＜ 0.05).The recurrence rate and distant metastasis rate of stage N1 patients were significantly higher than that of N0 patients (x2 =7.764-56.495,P ＜ 0.05).The abdomen lymph nodes recurrence rate of stage N1 patients was significantly higher than that of N0 in upper TESCC (x2 =7.905,P ＜0.05).The supraclavicular and intrathoracic lymph nodes recurrence rates of stage N1 patients were significantly higher than that of N0 patients in middle TESCC (x2 =12.506,18.436,P ＜ 0.05).The supraclavicular lymph nodes,anastomosis and abdomen lymph node recurrence rates of stage N1 were significantly higher than that of N0 patients in lower TESCC (x5 =5.272,4.878,18.006,P ＜ 0.05).The anastomotic recurrence rate of stage T3+4 was higher than that of T1+2 in middle/lower TESCC (x2 =4.341,7.154,P ＜ 0.05),and the abdominal lymph nodes recurrence rate of stage T3 +4 was higher than that of T1 +2 in lower TESCC (x2 =5.366,P ＜ 0.05).Conclusions The lymphatic drainage regions for postoperative radiotherapy (PORT) are selective.We suggest that abdominal lymph nodes drainage area should be noted for the stage N1 patients with upper TESCC,and the supraclavicular lymph nodes drainage area should be noted for the N1 patients with lower TESCC.In addition,the anastomosis is suggested to be included in PORT target area for stage T3/T4 middle/lower TESCC patients.

Objective To compare the prognosis of patients with squamous cell carcinona of the upper thoracic esophagus after radical resection with and without postoperative chemoradiotherapy (POCRT).Methods From January 2007 to December 2011,168 patients with upper thoracic esophageal carcinoma who were treated in the Fourth Hospital of Hebei Medical University were retrospectively included in this study.According to the different treatment method,they were divided into simple surgery group (86 cases) and POCRT group (82 cases) respectively.Based on SPSS statistical software,the group data composition,prognostic analysis and multivariate prognostic analysis were performed by x2 test,Log-rank method and Cox regression model,respectively.Results The 1,3,5 year-survival rate,recurrence rate and distant metastasis rate were 83.9％,52.4％,43.5％,26.5％,40.8％,43.4％ and 5.3％,11.4％,16.9％,respectively.The result of multivariate analysis showed that gender,T stage,N stage and treatment method were independent prognostic factors of overall survival (P =0.020,0.008,0.005,0.000);N staging and treatment method were the independent prognostic factors of local/regional recurrence (P =0.001,0.003);differentiation and T staging were the independent prognostic factors of distant metastasis (P =0.045,0.020).The intrathoracic regional recurrence rate of operation only group and POCRT group patients were 44.2％ (38/86) and 29.3％ (24/82) respectively,where the difference was statistically significant (x2 =7.110,P ＜ 0.05).The rate of metastasis were 19.8％ (17/86) and 13.4％ (11/82) respectively without significant difference (P ＞0.05).Conclusions The recurrence rate of patients with upper thoracic esophageal squamous cell carcinoma after radical resection was still high.Postoperative chemoradiotherapy can improve the overall survival rate and reduce the recurrence rate,but whether it can reduce the patient's distant metastasis rate needs further study.

Objective To analyze the risk factors for abdominal lymph node recurrence after radical surgery in patients with middle thoracic esophageal squamous cell carcinoma (TE-SCC),and to design the target volume for postoperative radiotherapy based on the results.Methods A retrospective study was performed among 913 patients with middle TE-SCC undergoing radical surgery who were admitted to our hospital from 2007 to 2012.Influencing factors were analyzed for abdominal lymph node recurrence after treatment.The efficacy was compared between different treatment methods in the high-risk population.Comparison of categorical data was made by chi-square test.The overall survival rates (OS) were calculated by the Kaplan-Meier method and analyzed by the univariate log-rank analysis.The influencing factors for abdominal lymph node recurrence were analyzed by the multivariate logistic regression equation.Results After treatment,37 patients had abdominal lymph node recurrence,yielding a recurrence rate of 4.1％.A total of 53 recurrent sites were found.The univariate analysis showed that no/low differentiation,pT3+4 stage,no less than 3 positive postoperative lymph nodes,and positive postoperative abdominal lymph nodes were influencing factors for abdominal lymph node recurrence (P =0.032,0.001,0.009,0.000).The multivariate regression analysis showed that pathological T staging and positive postoperative abdominal lymph nodes were influencing factors for abdominal lymph node recurrence (P=0.011,0.000).For patients with pT3+4 stage disease and positive postoperative abdominal lymph nodes,postoperative radiotherapy improved OS and local control rates but failed to reduce the distant metastasis-free rate.Conclusions T staging and positive postoperative abdominal lymph nodes are important risk factors for abdominal lymph node recurrence after radical surgery in patients with middle TE-SCC.Postoperative adjuvant therapy is recommended for patients with pT3+4 stage disease and positive postoperative abdominal lymph nodes.

Objective To compare the efficacy between different modalities in the treatment of positive lymph nodes after radical resection for squamous cell carcinoma of thoracic esophagus(TESCC),and to explore the best treatment mode. The Kaplan?Meier method was used to calculate survival rates. The log-rank test and Cox model were used for univariate and multivariate prognostic analyses,respectively. Methods A retrospective analysis was performed among 548 patients with TESCC who were admitted to our hospital and had positive lymph nodes after radical resection. The efficacy of different treatment methods was evaluated. Propensity scores(PSM)were used to make 1-to-1 patient matching between different treatment groups to further analyze and figure out the best treatment model for patients. The Kaplan?Meier method was used to calculate the overall survival(OS)and disease-free survival(DFS)rates. The log-rank test was used for survival analysis and univariate prognostic analysis. The Cox regression model was used for multivariate prognostic analysis. Results In all patients,the 1-,3-,and 5-year OS rates were 79.9%, 38.1% and 28.5%,respectively,while the 1-,3-,and 5-year DFS rates were 68.5%,39.8% and 32.5%, respectively. After 1-to-1 matching based on PSM,there were no differences in general clinical pathological data between the four groups. After PSM,there were significant differences in 1-,3-,and 5-year OS and DFS rates between the surgery alone group,the postoperative radiotherapy group,the postoperative chemotherapy group,and the postoperative chemoradiotherapy(POCRT)group(P=0.000,0.000).There were significant differences in OS and DFS rates between patients with stage N1,N2,and N3disease(P=0.000,0.000).The result of the Cox multivariate analysis showed that treatment method and N staging were two independent prognostic factors for OS and DFS(P=0.001,0.000,0.025,0.016). Conclusions Patients with positive lymph nodes after radical resection for TESCC have a poor prognosis. Moreover,the prognosis becomes worse with the increase in metastatic lymph nodes. POCRT may improve the survival in those patients. Prospective studies are needed to further confirm those conclusions.

Objective To evaluation and comparison the curative effect of different adjuvant therapy and prognostic factors with thoracic esophageal squamous cell carcinoma (ESCC) after surgery,and to find the best treatment for them.Methods A total of 863 patients with thoracic ESCC underwent surgery in the fourth hospital of Hebei Medical University,From January 2007 to December 2010,To analyze the influence factors of the patient′s independent prognosis and the effect of postoperative adjuvant therapy on the prognosis of patients.The 1:1, after the tendency of a total of 261 cases were used PSM method (87 cases/group).The Kaplan-Meier method was used to calculate OS,DFS and log-rank test and monovariable analysis,Cox model was used to multivariable analysis.Results The sample size in 1,3,5 was 123,589,863 cases.The 1-,3-,and 5-year overall survival (OS) and disease-free survival (DFS) of all patients were 89.7%,62.1%,51.7% and 76.8%,52.1%,44.2%,respectively.The 1,3,5-years of OS and DFS were 956%,73.3%,61.1% and 85.6%,61.1%,54.4%,78.9%,38.9%,31.3% and 67.8%,27.8%,20.0%,92.2%,55.6%,44.4% and 67.8%,44.4%,36.7%(all P=0.000) among postoperation chemoradiotherapy (POCRT),postoperation chemotherapy (POCT) and postoperation radiotherapy (PORT) after pairing with PSM.The result of COX analysis showed that the degree of inflammatory adhesion,pTNM stage and the number of positive lymph nodes were the independent prognostic factors in patients with OS (P=0.002,0.000,0.007).The history of drinking,pTNM stage and treatment model were the independent prognostic factors of DFS (P=0.009,0.000,0.012).Conclusions Patients with thoracic esophageal squamous cell carcinoma after surgery to receive adjuvant therapy has a good effect,compared with PORT and POCT,POCRT can significantly improve the OS and DFS,and POCRT was the independent prognostic factors of DFS.

Objective To investigate the failure model of patients with stage pN0 thoracic esophageal squamous cell carcinoma (TESCC) after surgery alone and to discuss the feasibility of postoperative radiotherapy.Methods A retrospective analysis was performed on 473 patients with TESCC who received surgery alone from January 2007 to December 2010.The feasibility of adjuvant radiotherapy for pN0 TESCC patients was investigated through the failure model of postoperative patients.Results Of all patients,there were 57 cases with chest-regional recurrence (12.1％),most of which occurred in the mediastinal lymph nodes(52 case).There were 42 (8.9％) patients were identified as distant metastasis (DM),of which 13 cases were found to have both local recurrence and DM,and the total failure rate was 20.9％.The chest-regional recurrence rate of upper TESCC was statistically significantly higher than middle and lower (x2 =7.469,P ＜ 0.05),but DM rate had no statistically significant difference (P ＞ 0.05).The chest-regional recurrence rate and DM rate of the advanced T stage were significantly higher than those of the early T stage(x2 =10.247,7.886,P ＜ 0.05).The result of univariate analysis showed that disease site,the degree of adhesion,postoperative stump were significant factors of chestregional recurrence rate (x2 =14.232,9.486,7.546,P ＜ 0.05).Gender,smoking and preoperative weight loss ≥5 kg significantly influenced DM (x2 =10.823,10.275,6.065,P ＜ 0.05).In addition,the T stage was the significant influence factor of chest-regional recurrence and DM(x2 =15.994,12.885,P ＜0.05).The result of multivariate analysis showed that T stage and postoperative stump were independent factors of chest-regional recurrence (P ＜ 0.05).Smoking was an independent factor of DM (P ＜ 0.05).Conclusions There was a high rate of chest-regional recurrence in patients with stage pN0 TESCC who received surgery alone.Postoperative radiotherapy was recommended for patients with upper TESCC,advanced T stage,severe local adhesion,positive margin in and postoperative stump.Male,smoking and preoperative weight loss≥5 kg were associated with higher DM rate.
