ObjectiveTo investigate the effects of Qizhujianwei granules （QZJW） on abnormal proliferation and malignant transformation of gastric mucosal cells in rats with gastric intraepithelial neoplasia （GIN） and to explore the related mechanisms. MethodsA total of 80 SPF male Wistar rats were used. A GIN rat model was established using a four-factor comprehensive method consisting of methylnitronitrosoguanidine （MNNG）， ranitidine， irregular feeding patterns， and sodium salicylate. Except for the normal group， after successful modeling， the rats were randomly divided according to body weight into a model group， a Moluodan group （0.55 g·kg^-1）， and a QZJW group （7.34 g·kg^-1）， with 12 rats in each group. All groups were treated for 8 weeks. The general characteristics of the rats and morphological changes of the gastric mucosa were observed. Histopathological changes of the gastric mucosa were examined by hematoxylin-eosin （HE） staining. Enzyme-linked immunosorbent assay （ELISA） was used to detect serum levels of pepsinogenⅠ （PGⅠ）， pepsinogenⅡ （PGⅡ）， and gastrin （G-17）， as well as the expression level of transforming growth factor-β₁ （TGF-β₁） in gastric mucosal tissue， and the PGⅠ/PGⅡ ratio was calculated. Immunohistochemistry （IHC） was used to detect the localization and expression levels of proliferating cell nuclear antigen （Ki-67） and Vimentin in gastric mucosal tissue. Western blot analysis was used to determine the protein expression levels of Wnt family member 3A （Wnt3a）， β-catenin， CyclinD₁， proto-oncogene Cmyc， transforming growth factor-β receptor Ⅰ （TGFβRⅠ）， intracellular signaling transducers Smad2/3， phosphorylated （p）-Smad2/3， twist family transcription factor （Twist1）， and Vimentin in gastric mucosal tissue. ResultsCompared with the normal group， the model group showed characteristic changes including dim eyes， pale ears and claws， dark-red tongue， and reduced luster of the tail. The gastric mucosa appeared pale， with surface congestion and erosion. The gastric mucosal glands were disordered， the nuclear-to-cytoplasmic ratio increased， and local tumor cells were observed. Serum PGⅠ and PGⅡ levels and the PGⅠ/PGⅡ ratio were significantly decreased （P<0.01）， while the level of G-17 was significantly increased （P<0.01）. The protein expression levels of Ki-67， Wnt3a， β-catenin， CyclinD₁， Cmyc， TGF-β₁， TGFβRⅠ， Smad2/3， Twist1， and Vimentin in gastric mucosal tissue were significantly increased （P<0.05， P<0.01）， whereas the ratio of p-Smad2/3 to Smad2/3 was significantly decreased （P<0.05）. Compared with the model group， the general characteristics and gastric mucosal conditions of rats in the Moluodan group and the QZJW group were improved. HE staining showed that QZJW could effectively block the malignant progression of GIN. Serum PGⅠ and PGⅡ levels and the PGⅠ/PGⅡ ratio were significantly increased （P<0.05， P<0.01）， while the level of G-17 was significantly decreased （P<0.01）. The protein expression levels of Ki-67， Wnt3a， β-catenin， CyclinD₁， Cmyc， TGF-β₁， TGFβRⅠ， Smad2/3， Twist1， and Vimentin in gastric mucosal tissue were significantly decreased （P<0.05， P<0.01）. ConclusionQZJW have a therapeutic effect on rats with GIN. The mechanism may involve inhibition of the Wnt/β-catenin signaling pathway to regulate the cell cycle and suppress abnormal cell proliferation. Meanwhile， it may inhibit epithelial-mesenchymal transition by suppressing the TGF-β₁/Smad/Twist1 signaling pathway， thereby blocking the malignant progression of GIN.

ObjectiveTo identify the independent risk factors for pyloric lymph node （PLN） metastasis in patients with upper gastric cancer （UGC） and to construct a nomogram prediction model applicable for UGC patients. MethodsClinical data of 823 UGC patients attended between January 2020 and November 2023 were retrospectively collected. Patients were randomly divided into a training set （n=576） and a validation set （n=247） at a 7∶3 ratio. Based on the training set， multivariate Logistic regression analysis was performed to identify independent risk factors for PLN metastasis， and a nomogram prediction model was constructed accordingly. The model's discriminative ability and calibration were assessed using receiver operating characteristic （ROC） curves and calibration curves. Finally， external validation was conducted using the validation set to evaluate the model's stability and generalizability. ResultsMultivariate Logistic regression analysis revealed that tumor size （OR=1.324， 95%CI： 1.053-1.667）， T3 stage （OR=5.738， 95%CI： 1.281-25.695）， T4 stage （OR=7.680， 95%CI： 1.542-38.247）， lymphovascular invasion （LVI） （OR=6.623， 95%CI： 1.384-31.708）， differentiation extent （OR=3.108， 95%CI： 1.545-6.251）， and fibrinogen degradation product （FDP） level （OR=4.849， 95%CI： 2.071-11.355） were independent risk factors for PLN metastasis in UGC patients.The nomogram model constructed based on these factors demonstrated areas under the ROC curve （AUC） of 0.815 （95%CI： 0.751-0.815） in the training set and 0.832 （95%CI： 0.731-0.933） in the validation set. Calibration curves indicated good agreement between predicted and observed outcomes. ConclusionThis nomogram prediction model exhibits good predictive performance for assessing the risk of PLN metastasis in UGC patients.

Objective To explore the predictive effect of serum 25-hydroxyvitamin D3 [25(OH)D3] and blood lipid metabolism indexes on the occurrence of osteoporosis in type 2 diabetes mellitus (T2DM). Methods Totally 98 patients with T2DM in the hospital from January 2022 to January 2024 were classified into osteoporosis group (38 cases) and non-osteoporosis group (60 cases) by means of concurrent osteoporosis status. The levels of serum 25(OH)D3 and blood lipid metabolism indexes [high density lipoprotein (HDL), total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL), VLDL] were measured in study subjects. The association of serum 25(OH)D3 and blood lipid metabolism indexes with osteoporosis was explored by Logistic regression analysis. The predictive value of serum 25(OH)D3 and blood lipid metabolism indexes on osteoporosis was analyzed by receiver operating characteristic curve (ROC). Results Serum 25(OH)D3 and HDL levels in the osteoporosis group were lower while TG and LDL levels were higher than those in the non-osteoporosis group (P<0.05). The differences in the levels of TC and VLDL were insignificant between groups (P>0.05). After logistic regression analysis, the levels of serum 25(OH)D3, HDL, TG and LDL were closely related to the occurrence of osteoporosis (P<0.05). ROC curve indicated that the area under the curve (AUC), sensitivity and specificity of combined prediction of osteoporosis by serum 25(OH)D3, HDL, TG, and LDL were 0.943, 92.11% and 85.00%, and the efficiency of combined prediction was better than that of each index alone (P<0.05). Conclusion The levels of serum 25(OH)D3, HDL, TG and LDL in T2DM are closely related to osteoporosis. Early combined monitoring of the indicators can provide reference value for clinical prediction of osteoporosis occurrence in patients with T2DM.

Objective: To analyze the prevalence and the related factors of comorbidity of overweight/obesity and elevated blood pressure among primary and secondary school students in Changchun, so as to provide a basis for the intervention strategies of multiple disease prevention among primary and secondary school students. Methods: From September to October 2023，a stratified cluster random sampling method was used to select 32 552 primary and secondary school students aged 7 to 18 from 16 counties (cities) and districts in Changchun City for physical examinations and questionnaires on behavioral patterns. The Chi-square test was used for intergroup comparison and unconditional Logistic regression model was used for analyzing related factors of comorbidity presence of overweight/obesity and elevated blood pressure among primary and secondary school students. Results: The detection rate of comorbidity of overweight/obesity and elevated blood pressure among primary and secondary school students was 8.7%.The detection rate of boys(10.1%) was higher than that of girls(7.3%), the detection rate was higher among students in urban areas ( 10.6 %) than that in suburban areas(5.7%); and the detection rate among vocation high school students(15.7%) was higher than that in general high school students (11.8%), junior high school students (10.2%) and primary school students (5.3%).All the differences were statistically significant （χ 2=84.67, 239.28, 468.64 ,all P <0.01).The results of the multivariate Logistic regression analysis showed that daily moderate to vigorous physical activity for 60 minutes or more ( OR =0.70) was associated with a reduced risk of comorbidity of overweight/obesity and elevated blood pressure among primary and secondary school students; boys ( OR = 1.46 ), urban residents ( OR =1.70),junior high school students( OR =1.78), general high school students ( OR =1.97), vocational high school students ( OR =2.20), and screen time without meeting the standard( OR =1.11) were associated with an increased risk of comorbidity of overweight/obesity and elevated blood pressure among primary and secondary school students(all P <0.05). Conclusions The comorbidity detection rate of overweight/obesity and elevated blood pressure and obesity among primary and secondary school students in Changchun is relatively high. Targeted measures should be developed to reduce the occurrence of overweight/obesity and elevated blood pressure with comorbidity of them.

Oral squamous cell carcinoma (OSCC) is a common head and neck malignancy. Approximately 50% to 60% of patients with OSCC are diagnosed at a locally advanced stage (clinical staging III-IVa). Even with comprehensive and sequential treatment primarily based on surgery, the 5-year overall survival rate remains below 50%, and patients often suffer from postoperative functional impairments such as difficulties with speaking and swallowing. Programmed death receptor-1 (PD-1) inhibitors are increasingly used in the neoadjuvant treatment of locally advanced OSCC and have shown encouraging efficacy. However, clinical practice still faces key challenges, including the definition of indications, optimization of combination regimens, and standards for efficacy evaluation. Based on the latest research advances worldwide and the clinical experience of the expert group, this expert consensus systematically evaluates the application of PD-1 inhibitors in the neoadjuvant treatment of locally advanced OSCC, covering combination strategies, treatment cycles and surgical timing, efficacy assessment, use of biomarkers, management of special populations and immune related adverse events, principles for immunotherapy rechallenge, and function preservation strategies. After multiple rounds of panel discussion and through anonymous voting using the Delphi method, the following consensus statements have been formulated: 1) Neoadjuvant therapy with PD-1 inhibitors can be used preoperatively in patients with locally advanced OSCC. The preferred regimen is a PD-1 inhibitor combined with platinum based chemotherapy, administered for 2-3 cycles. 2) During the efficacy evaluation of neoadjuvant therapy, radiographic assessment should follow the dual criteria of Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 and immune RECIST (iRECIST). After surgery, systematic pathological evaluation of both the primary lesion and regional lymph nodes is required. For combination chemotherapy regimens, PD-L1 expression and combined positive score need not be used as mandatory inclusion or exclusion criteria. 3) For special populations such as the elderly (≥ 70 years), individuals with stable HIV viral load, and carriers of chronic HBV/HCV, PD-1 inhibitors may be used cautiously under the guidance of a multidisciplinary team (MDT), with close monitoring for adverse events. 4) For patients with a poor response to neoadjuvant therapy, continuation of the original treatment regimen is not recommended; the subsequent treatment plan should be adjusted promptly after MDT assessment. Organ transplant recipients and patients with active autoimmune diseases are not recommended to receive neoadjuvant PD-1 inhibitor therapy due to the high risk of immune related activation. Rechallenge is generally not advised for patients who have experienced high risk immune related adverse events such as immune mediated myocarditis, neurotoxicity, or pneumonitis. 5) For patients with a good pathological response, individualized de escalation surgery and function preservation strategies can be explored. This consensus aims to promote the standardized, safe, and precise application of neoadjuvant PD-1 inhibitor strategies in the management of locally advanced OSCC patients.

摘要 目的 肝豆状核变性（又称Wilson病，WD）是由ATP7B基因突变引起的铜代谢紊乱疾病，常累及肝脏和中枢神经系统，严重者可致死。目前关于WD患者死亡原因及危险因素的系统研究较少。本研究旨在探讨WD患者的常见死亡原因及其危险因素。方法 回顾性分析2011年1月—2022年1月间安徽中医药大学神经病学研究所附属医院87例死亡WD患者和113例存活WD患者的临床资料，分析死亡原因，并通过Cox回归分析死亡危险因素。结果 死亡组年龄中位数为32.00（27.00，41.00）岁、病程中位数为144.00（72.00，228.00）个月，存活组年龄中位数为31.00（25.00，37.00）岁、病程中位数为132.00（72.00，214.00）个月。主要死亡原因包括肝衰竭（33例）、感染（23例）、猝死（8例）、消化道出血（8例）及肝癌（4例）等。死亡组与存活组在性别、起病形式、低铜饮食、肝脏B超分型、脾脏切除、临床分型、治疗方案及多项实验室指标（如白细胞计数、TB、Alb等）上差异有统计学意义（P<0.05）。多因素Cox回归显示，基线尿铜每增加100 μg/24 h（HR=1.22， 95%CI 1.11~1.34）与肝硬化（HR=2.55，95%CI 1.02~6.36）使死亡风险增加。结论 WD患者的主要死亡原因为肝衰竭，高水平基线尿铜和肝硬化显著增加死亡风险。尿铜水平达400 μg/24 h（参考值<100 μg/24 h）的患者死亡风险较基线增加3.8倍（HR=3.8，P<0.001）。研究结果为WD患者的预后评估和临床干预提供了重要依据。 Abstract Objective Hepatolenticular degeneration（also know as Wilson disease ，WD） is a copper metabolic disorder caused by ATP7B gene mutation， often involving the liver and the central nervous system and leading to death in severe cases. At present， there is a lack of systematic studies on the cause of death and related risk factors in WD patients. Therefore， this study aims to investigate the common causes of death and related risk factors in WD patients. Methods A retrospective analysis was performed for the clinical data of 87 WD patients who died and 113 WD patients who survived in our hospital from January 2011 to January 2022. The common causes of death in WD patients were analyzed， and the Cox proportional-hazards regression model analysis was used to investigate the risk factors for death. Results The death group had a median age of 32.00 （27.00，41.00） years and a median course of disease of 144.00 （72.00，228.00） months， and the survival group had a median age of 31.00 （25.00，37.00） years and a median course of disease of 132.00 （72.00，214.00） months. The main causes of death included liver failure （33 patients）， infection （23 patients）， sudden death （8 patients）， gastrointestinal bleeding （8 patients）， and liver cancer （4 patients）. There were significant differences between the death group and the survival group in sex， pattern of disease onset， low copper diet， liver ultrasound classification， splenectomy， clinical classification， treatment regimens， and various laboratory markers （such as white blood cell count， total bilirubin， and albumin）（P<0.05）. The multivariate Cox regression analysis showed that the risk of death was doubled for every 100 μg/24 h increase in urinary copper at baseline （HR=1.22，95%CI 1.11-1.34） and the presence of liver cirrhosis （HR=2.55，95%CI 1.02-6.36）. Conclusion Liver failure is the main cause of death in WD patients， and a high level of urinary copper at baseline and the presence of liver cirrhosis significantly increase the risk of death. The risk of death in patients with a urinary copper level of 400 μg/24 h （reference value<100 μg/24 h） was increased by 3.8 times compared with the value at baseline （HR=3.8，P<0.001）.The results of this study provide an important basis for the prognosis evaluation and clinical intervention of WD patients.

Objective: To evaluate the intervention effectiveness of co-occurrence and prevention for myopia and obesity among primary and secondary school students, so as to provide a scientific basis for the development of comprehensive intervention measures in myopia and obesity. Methods: From September 2022 to September 2023, a cluster random sampling method was used to select 6 primary schools and 6 junior high schools from Tongzhou District, Beijing. Participants were randomly assigned to an intervention group (914 before intervention and 754 after intervention) and a control group (868 before intervention and 652 after intervention), with an expected duration of one academic year. Based on the RE-AIM framework, integrate resources from families, schools, communities, and medical institutions to develop a school-based intervention technology packagefor the co-occurrence and prevention of myopia and obesity in children. The intervention group received intervention according to the comprehensive intervention technology package, while the control group did not receive any intervention measures. Relevant health indicators during the baseline period and after intervention were measured and collected, and groups were compared by Chi quest test, t-test and Wilcoxon rank sum test. Results: After intervention, the uncorrected visual acuity of primary and secondary school students in the intervention group (4.79±0.30) and the control group (4.77±0.33) both decreased compared to those before intervention (4.80±0.30, 4.90±0.32) ( t =-7.00,-5.24); the decrease in uncorrected visual acuity in the intervention group was smaller than that in the control group( t =5.33)( P <0.01). After intervention, body mass index, waist circumference, hip circumference, and body fat percentage of primary and secondary school students in the intervention group decreased compared to those before intervention. However, the changes in these indicators were not statistically significant ( t/Z =-0.03, - 0.36，- 0.30，- 0.01, P >0.05); the above indicators in the control group increased compared to those before intervention, but only hip circumference and body fat percentage showed statistically significant changes ( t/Z =2.17, 2.62, P <0.05). After intervention, both the intervention group and the control group showed increases in systolic and diastolic blood pressure compared to those before intervention(intervention group: t =2.16,5.29; control group: t =6.84,5.07); the intervention group had lower systolic and diastolic blood pressure than the control group( t = -5.27 , -2.08)( P <0.05). After intervention, the intervention and the control groups had statistically significant differences in cognitive accuracy(92.48%, 69.33%) in terms of "outdoor exercise can prevent myopia" and "having 5 servings of adult fist sized vegetables and fruits every day" ( χ 2=6.30, 7.86, P <0.05). There was a statistically significant difference in the proportion of primary and secondary school students in the intervention group (40.98%) and the control group (35.43%) for "who did not drink sugary drinks for every day in the past 7 days" ( χ 2=4.32, P <0.05). After intervention, the intervention group and the control group showed increases in "school outdoor activity duration on school days" and "outdoor activity duration on rest days" compared to those before intervention ( t/Z =-13.32,-9.71;- 2.59，-2.69）；the behavior rate of "visual acuity measurement frequency at least once every 3 months" in the intervention group (46.68%) and the control group (52.76%) increased compared to those before intervention (36.43%, 44.01%), and the increases in the intervention group were greater than that in the control group ( χ 2=17.52,11.08) ( P <0.05). Conclusions Comprehensive intervention measures have significant intervention effects on controlling the occurrence and development of comorbidity of myopia and obesity in children. It could actively promote collaboration and cooperation among families, schools, communities and medical institutions to reduce the occurrence of myopia and obesity among primary and secondary school students.

Objective:To analyze the risk factors of prognosis in patients with intracranial solitary fibrous tumor/hemangiopericytoma (SFT/HPC).Methods:The clinical data of 74 intracranial SFT/HPC patients underwent surgical treatment from January 2017 to January 2024 in Luhe Hospital, Capital Medical University and Sanbo Brain Hospital, Capital Medical University were retrospectively analyzed. The patients were followed up the prognosis (including recurrence, death and extracranial metastasis). Kaplan-Meier and log-rank tests were used to analyze the risk factors of prognosis in patients with intracranial SFT/HPC, and multivariate Cox analysis was used to analyze the independent risk factors of prognosis in patients with intracranial SFT/HPC.Results:Seventy-four patients with intracranial SFT/HPC were followed up for 3 to 80 months, averaging 52.5 months. Among them, there were 17 cases of recurrence, 6 cases of extracranial metastasis, and 12 cases of death. In patients with intracranial SFT/HPC, the results of the log-rank univariate analysis showed that the tumor location, resection extent, WHO pathological grade, and adjuvant radiotherapy were risk factors of recurrence ( P<0.01); the tumor location, WHO pathological grade and extracranial metastasis were risk factors of death ( P<0.05 or <0.01); and the age, WHO pathological grade and Ki67 were risk factors of extracranial metastasis ( P<0.05 or <0.01). In patients with intracranial SFT/HPC, multivariate Cox regression analysis result showed that the subtotal resection and non-postoperative radiation therapy were independent risk factors of recurrence ( HR = 0.377 and 0.315, 95% CI 0.148 to 0.932 and 0.164 to 2.221, P<0.01 and <0.05); the WHO pathological grade Ⅲ and extracranial metastasis were independent risk factors of death ( HR = 3.657 and 1.657, 95% CI 0.964 to 7.147 and 0.964 to 2.848, P<0.01); the WHO pathological grade Ⅲ was an independent risk factor of extracranial metastasis ( HR = 1.657, 95% CI 0.964 to 2.848, P<0.01). Conclusions:Patients with intracranial SFT/HPC who undergo subtotal resection and non-postoperative radiation therapy are more prone to recurrence, WHO pathological grade Ⅲ patients are more likely to develop extracranial metastases, and extracranial metastases patients have shorter survival. For intracranial SFT/HPC patients with pathologically high-grade, SFT/HPC, it is necessary to increase the frequency of follow-ups and be alert for extracranial metastasis.

Objective To explore the effectiveness of the OKR method in improving the efficiency of the whole process of critical value management,and to provide new ideas for the implementation of medical quality improvement in other medical insti-tutions.Methods A hospital in Tianjin was selected as the study object,which used the OKR method to reform the management of critical value since January 2024.The core goal of"improving the effectiveness of critical value management"was set,and the goal was broken down into quantitative key results such as"the rate of receiving the critical value system is over 95％"and"the rate of completing the standardised writing of medical records is up to 85％".Results After the reform,several quantitative key results,such as the completion rate of critical care medical record writing,the rate of standardised medical record writing,and the rate of overtime acceptance,were all better than before.Conclusion Through the OKR method to unify the whole hospital's strategic objectives,and the dynamic adjustment of the program based on data review,the hospital's critical value management efficiency has been significantly improved,effectively guaranteeing the safety of patients,and providing new perspectives and methods for the management of critical value in other medical institutions.
