Objective To investigatethe relationship between gastroesophageal reflux disease (GERD) symptoms and clinicopathological characteristics, p53 expression, and survival of Chinese patients with esophageal adenocarcinoma. Methods A total of 3882 patients with esophageal adenocarcinoma, 970 matched patients with esophageal squamous cell carcinoma, and 970 matched patients with gastric cardia adenocarcinoma were included to compare the incidence of GERD symptoms. Patients with esophageal adenocarcinoma were divided into two groups according to the presence and absence of GERD symptoms. The differences in clinicopathological characteristics and p53 expression between the two groups were compared by chi-square test, and the differences in survival between the two groups were compared by landmark analysis. Results The incidence of GERD symptoms increased successively in esophageal squamous cell carcinoma, esophageal adenocarcinoma, and gastric cardia adenocarcinoma. In patients with esophageal adenocarcinoma, the proportions of male, less than 65 years old, lower thoracic tumors, tumors without squamous cell carcinoma, poorly differentiation, early tumors (stage 0-I), and p53-positive tumors in the group with GERD symptoms were higher than those in the group without GERD symptoms; moreover, the long-term survival (≥15 years) was better. Conclusion GERD symptom is an important clinical sign of esophageal adenocarcinoma. It is closely related to specific clinicopathological characteristics, p53 overexpression, and good long-term prognosis.

Objective To explore the mechanism of immediate effect regulated by acupuncture on acupoints in patients with migraine without aura(MwoA)during the interictal period.Methods A total of 28 MwoA patients were enrolled and resting-state functional magnetic resonance imaging(rs-fMRI)were performed at baseline and after acupuncture for 30 minutes.Paired t test was used to compare the differences of regional homogeneity(ReHo)and voxel-mirrored homotopic connectivity(VMHC)between two groups.Additionally,the correlation between the changes of rs-fMRI indexes and clinical scores was analyzed.Results In MwoA patients after acupuncture for 30 minutes,the mean regional homogeneity(mReHo)was decreased in the right lingual gyrus and right cere-bellum and was increased in the right middle frontal gyrus,while the z transformation voxel-mirrored homotopic connectivity(zVMHC)was significantly decreased in the bilateral cuneus compared with baseline.There was no significant correlation between imaging data and clinical scales.Conclusion Patients with MwoA after acupuncture for 30 minutes show abnormal ReHo and VMHC in multiple brain regions,which suggest that the mechanism of immediate effect may act through regulating pain-related brain regions.

Malocclusion,identified by the World Health Organization(WHO)as one of three major oral diseases,profoundly impacts the dental-maxillofacial functions,facial esthetics,and long-term development of～260 million children in China.Beyond its physical manifestations,malocclusion also significantly influences the psycho-social well-being of these children.Timely intervention in malocclusion can foster an environment conducive to dental-maxillofacial development and substantially decrease the incidence of malocclusion or reduce the severity and complexity of malocclusion in the permanent dentition,by mitigating the negative impact of abnormal environmental influences on the growth.Early orthodontic treatment encompasses accurate identification and treatment of dental and maxillofacial morphological and functional abnormalities during various stages of dental-maxillofacial development,ranging from fetal stages to the early permanent dentition phase.From an economic and societal standpoint,the urgency for effective early orthodontic treatments for malocclusions in childhood cannot be overstated,underlining its profound practical and social importance.This consensus paper discusses the characteristics and the detrimental effects of malocclusion in children,emphasizing critical need for early treatment.It elaborates on corresponding core principles and fundamental approaches in early orthodontics,proposing comprehensive guidance for preventive and interceptive orthodontic treatment,serving as a reference for clinicians engaged in early orthodontic treatment.

Objective:To evaluate the effect of workshop-based incontinence associated dermatitis (IAD) training course for geriatric nurse specialists, and to provide references and evidence for the application of workshop teaching model in specialized nursing training.Methods:The convenience sampling method was used to select 40 participants in the 9th Chongqing Geriatric Nurse Specialist Training Program in May 2021 as the intervention group, and IAD training was conducted using the workshop method. The 42 participants in the 8th Chongqing Geriatric Nurse Specialist Training Program in May 2020 were selected as the control group, who received IAD training through traditional teaching methods. After the training, the achievement of teaching objectives and teaching satisfaction were compared between the two groups using questionnaire survey, and IAD nursing knowledge and attitudes were compared using scales. SPSS 27.0 was used for the t-test and chi-square test. Results:The questionnaire survey showed that the intervention group achieved higher teaching objectives in all dimensions compared to the control group ( P<0.05). Compared with the control group, the intervention group had higher scores in teaching satisfaction regarding teaching format, interest in learning, practical skills, theoretical understanding, integration of theory and practice, and problem-solving abilities ( P<0.05). Compared with the control group, the intervention group demonstrated significantly higher scores in IAD nursing knowledge [(11.32±1.56) vs. (9.02±2.26), P<0.05] and attitudes [(37.63±3.54) vs. (32.81±2.97), P<0.05]. Conclusions:The workshop training has been highly recognized by the trainees, contributing to improved implementation effectiveness of teaching, enhancing the scores of IAD nursing knowledge and attitudes. This approach offers a new perspective for training with a practical focus in the specialized nursing field.

Objective:To study the predictive role of tumor burden score (TBS) for tumor recurrence after radical resection in patients with hepatocellular carcinoma (HCC).Methods:Clinical data of 202 patients with HCC undergoing radical surgery at the 900th Hospital of Joint Logistics Support Force of the Chinese People's Liberation Army, between January 2015 and December 2017 were retrospectively analyzed, including 128 males and 74 females, aged (53.66±11.93) years old. The receiver operating characteristic (ROC) curve was used to assess the accuracy of TBS in predicting postoperative tumor recurrence. Univariate and multivariate logistic regression analyses were performed to identify independent risk factors influencing postoperative tumor recurrence. A nomogram was established and validated using calibration curves and the C-index. Kaplan-Meier survival analysis was utilized to compare survival differences between the two patient groups.Results:The area under the ROC curve for TBS in predicting postoperative tumor recurrence in HCC patients was 0.779 (95% CI: 0.717-0.842), with an optimal cutoff value of 6.2. Univariate analysis revealed that factors such as hepatitis B virus DNA level >500 IU/ml, larger maximum tumor dia-meter, and TBS>6.2 were significant risk factors for postoperative tumor recurrence (all P<0.05). Multivariate analysis further indicated that TBS>6.2 ( OR=3.60, 95% CI: 1.081-12.012, P=0.037) and maximum tumor diameter ( OR=1.240, 95% CI: 1.034-1.487, P=0.020) were independent risk factors for postoperative recurrence. Based on these risk factors, a nomogram model was established, achieving a C-index of 0.788. Kaplan-Meier survival analysis showed a better postoperative overall survival and recurrence-free survival of the low TBS group compared to those of the high TBS group (all P<0.05). Conclusion:TBS can serve as a predictive indicator for the recurrence after radical resection in patients with HCC. Both TBS and tumor size are independent risk factors for postoperative recurrence. The nomogram model can be used for predicting recurrence following radical resection in HCC patients.

Objective:To evaluate extrathecal vs. intrathecal approach of Glisson's pedicle in laparoscopic hepatectomy of hepatocellular carcinoma (HCC). Methods:Clinical data of 96 HCC patients receiving laparoscopic hepatectomy at the Department of Hepatobiliary Surgery, the 900 Hospital of the United Logistics Force from Jan 2019 to Jun 2022 were retrospectively analyzed. Thrity-six cases were treated with extrathecal approach of Glisson's pedicle and 60 cases were by intrathecal approach.All those 60 undergoing intrathecal approach cases were matched by 1∶1 propensity score matching, and the caliper value was 0.02. The duration of surgery, blocking-time of hepatoduodenal ligament, intraoperative blood loss, indexes of the liver function and the prothrombin time on the 1st day of the postoperative period, rate of the postoperative complications, postoperative hospital stay, postoperative survival and recurrence were compared between the two groups.Results:After propensity score matching, 32 cases in each group were identified. The operation time of the extrathecal group was shorter than that of the intrathecal group [(207.5±77.4) minutes vs. (248.6±74.7) minutes, P=0.03], the intraoperative bleeding volume was less than that of the intrathecal group [(150.0(100.0, 300.0) ml vs. 250.0(150.0, 587.5) ml, P=0.01], and the albumin level was higher on the 1st day after the surgery [(36.5±3.2) g/L vs. (34.3±3.2) g/L, P<0.01]. There was no statistically significant difference in postoperative liver function, coagulation, complications, hospitalization time, all over survival rate between the two groups (all P>0.05). Conclusion:Extrathecal approach for Glisson's pedicle is safe and feasible in laparoscopic hepatectomy for HCC, with simpler surgical procedure, less intraoperative trauma.

Objective:To analyze the demands of contracted family doctor service among uncontracted young and middle-aged people in Shanghai Baoshan.Methods:An online questionnaire survey on demands of contracted family doctor service was conducted in June 2021 among 702 uncontracted residents aged 18-60 years from Shanghai Baoshan district selected by stratified random sampling method. The demands of contracted family doctor service, including digital health file, routine laboratory tests and imaging investigation;health promotion;service convenience; home service were surveyed, and the factors related the demands were analyzed with regression analysis.Results:The survey showed that the demands of service convenience (3.8(3.0, 5.0)) and home service (4.0(3.0, 5.0)) were higher, while those of digital health file (3.0(2.0, 5.0)) and health promotion (3.0(2.0, 5.0)) were relatively lower. There were significant differences in the demands of all five contracted services among residents with different gender, age, education level, household register and family income (all P<0.05); while for young residents with different types of medical insurance there was significant difference in demands of all contracted services except digital health file (all P<0.05). Logistic regression analysis indicated that female( OR=1.83, P<0.001), high educational level( OR=4.81, P=0.019), household registered in Shanghai( OR=1.80, P=0.004)had higher demand for service convenience; female gender( OR=1.68, P=0.001), high educational level( OR=4.56, P=0.023)had higher demand for home service demands. Conclusion:The demands for contracted family doctor services are different among the uncontracted young and middle-aged people in Baoshan district, while the service convenience is generally most demanded. The study indicates that the contracted family doctor service should be provided accordingly.

Objective To identify the potential long non-coding RNA (lncRNA) expressed in rheumatoid arthritis (RA) synovium key to RA onset and investigate its association with immune cell infiltration. Methods RA synovium data were downloaded from the GEO database and normalized. The lncRNAs key to RA onset were identified using multiple machine learning methods. Infiltration of 22 immune cell populations in RA synovium was measured by cell-type identification by estimating relative subsets of RNA transcripts (CIBER-SORT). The relationship between the key lncRNA and infiltrating immune cells was analyzed. Finally, real-time quantitative PCR was applied to validate the expression of the key lncRNA in RA synovial cells. Results lncRNA human leukocyte antigen complex P5(HCP5) was identified as the key lncRNA associated with RA onset. Infiltration analysis revealed increased abundance of CD8⁺ T cells, γδ T cells, and M1 macrophages while decreased abundance of M2 macrophages in RA synovial tissue. Correlation analysis demonstrated that the lncRNA HCP5 expression was positively associated with the infiltration abundance of CD8⁺ T cells, γδ T cells, and M1 macrophages in RA synovial tissue. Furthermore,the expression of lncRNA HCP5 in RA synovial cells was up-regulated. Conclusion lncRNA HCP5 expression is up-regulated in RA synovial tissue and potentially associated with immune cells infiltration.

Objective To investigate the therapeutic effect and prognostic significance of lateral lymph node dissection (LPLND) in patients with lateral lymph node (LPLN) metastasis. Methods The clinicopathological data of rectal cancer patients who underwent total mesorectal excision (TME) combined with LPLND and pathologically confirmed as LPLN metastasis after operation were retrospectively analyzed. The clinicopathological characteristics and metastasis rules of patients with LPLN metastasis were discussed, and the survival prognosis after LPLND was analyzed. Results A total of 102 rectal cancer patients with pathologically confirmed LPLN metastasis were included. The common sites of LPLN metastasis were internal iliac vessels lymph nodes (n=68, 66.7%), followed by obturator lymph nodes (n=44, 43.1%), and common iliac vessels or external iliac vessels lymph nodes (n=12, 11.8%). There were 10 patients (9.8%) with bilateral LPLN metastases, and the mean number of LPLN metastases was 2.2±2.4, among which 16 patients (15.7%) had LPLN metastases number≥2. The 3-year OS (66.8% vs. 7.7%, P < 0.001) and DFS (39.1% vs. 10.5%, P=0.012) of patients with LPLN metastases to the external iliac or common iliac lymph node were significantly lower than those with metastases to the internal iliac or obturator lymph node. The multivariate analysis showed that LPLN metastasis to external iliac or common iliac lymph node was an independent risk factor both for OS (HR=3.53; 95%CI: 1.50-8.31; P=0.004) and DFS (HR=2.40; 95%CI: 1.05-5.47; P=0.037). Conclusion LPLN mainly metastasizes to the internal iliac or obturator lymph node areas. The survival of patients with metastasis to the external iliac or common iliac lymph node cannot be improved by LPLND, and thus systemic comprehensive treatment is often the optimal treatment option.

Objective:To investigate the prognostic value of metabolic parameters of 18F-fluorodeoxyglucose ( 18F-FDG) positron emission computed tomography/computed tomography(PET/CT) in advanced non-small cell lung cancer(NSCLC) treated with first-line immune checkpoint inhibitor (ICI) combined with chemotherapy. Methods:A retrospective study was conducted to evaluate patients with advanced NSCLC who underwent baseline PET/CT before treatment at the Affiliated Cancer Hospital of Zhengzhou University from 2019 to 2021. Receiver operating characteristic (ROC) curve analysis was used to determine the cut-offs for metabolic parameters of PET/CT, including total metabolic tumor volume (TMTV), total lesion glycolysis (TLG), and maximum standard uptake value (SUV max). Kaplan-Meier method, Log-rank test, and Cox regression model were used to calculate the overall survival (OS) and the progression-free survival(PFS). Results:A total of 44 patients were enrolled. Univariate analysis showed that the factors influencing PFS were TMTV and the number of metastatic sites ( χ2=4.19, 11.28, P<0.05) and the factors influencing OS were TMTV and TLG ( χ2=14.96, 6.05, P<0.05). Multivariate analysis suggested that number of metastatic sites was an independent prognostic marker for PFS ( P=0.011) and TMTV was an independent prognostic marker for OS ( P=0.038). Conclusions:TMTV is a prognostic indicator of OS while the number of metastatic sites is a prognostic indicator of PFS in advanced NSCLC patients who received first-line ICI combined with chemotherapy, but further prospective studies are needed.
