Rheumatoid arthritis （RA） is a chronic systemic autoimmune disease with complex pathogenesis， poor cure rate， long course of disease， and high disability rate， which seriously affects patients' quality of life. Western medicine treatment of RA mainly includes non-steroidal anti-inflammatory drugs， rheumatic drugs， glucocorticoids， biologics， and targeted small-molecule drugs， which have large side effects and many adverse reactions. Traditional Chinese medicine （TCM） has systematic， comprehensive， multi-target， and multi-mechanism advantages in the treatment of RA. Through the overall syndrome pattern identification， it is effective in relieving symptoms， delaying onset， and relieving pain in RA patients by dispelling wind and removing dampness， dissipating cold and dredging collaterals， clearing heat and removing toxin， resolving phlegm and removing blood stasis， and relaxing sinew and activating collaterals. In recent years， TCM has made remarkable progress in the intervention of RA by regulating the nuclear transcription factor-κB （NF-κB） signaling network. They include Toll-like receptor 4 （TLR4）， phosphoinositol 3 kinase （PI3K）/protein kinase B （Akt）， mitogen-activated protein kinase （MAPK）， Nod-like receptor protein 3 （NLRP3）， nuclear factor E₂ associated factor 2 （Nrf2）， Janus kinase 2 （JAK2）/signaling and transcriptional activator 3 （STAT3）， and Toll-like receptor 2 （TLR2）. The regulatory mechanism of NF-κB signaling network is complex： TLR4 is the upstream receptor of NF-κB， PI3K/Akt and MAPK pathways can not only regulate the activity of NF-κB， but also serve as its downstream effect pathway， Nrf2 and NF-κB often have antagonistic effects in the regulation of inflammatory response. Therefore， the research progress of regulating NF-κB signaling network by traditional Chinese medicine in the intervention of RA was summarized to provide a reference for the treatment of RA disease and the development of new drugs.

Objective: To investigate the recreational use status of electronic products among high school students in Shanxi Province and the influencing factors for excessive use, so as to provide insights into the promotion of rational use of electronic products among high school students. Methods: The high school students from 117 schools in Shanxi Province were selected using the stratified random sampling method, and basic information, lifestyle behaviors and recreational use of electronic products were collected using questionnaire surveys. The prevalence of excessive recreational use of electronic products was analyzed, and the factors affecting excessive recreational use of electronic products among high school students were analyzed using a multivariable logistic regression model. Results: A total of 13 804 valid questionnaires were recoverd, with an effective rate of 98.32%. There were 6 634 males (48.06%) and 7 170 females (51.94%), with a median age of 17.00 (interquartile range, 1.00) years. There were 7 024 students in Grade One (50.88%) and 6 780 students in Grade Two (49.12%). The prevalence of recreational use of electronic products was 14.18% (1 958 cases). Multivariable logistic regression analysis showed that males (OR=1.461, 95%CI: 1.325-1.611), students in Grade Two (OR=1.720, 95%CI: 1.559-1.897), students whose parents had below high school education (OR=1.391, 95%CI: 1.156-1.674), students without parental support (OR=1.281, 95%CI: 1.078-1.523), students not living on campus (OR=1.142, 95%CI: 1.026-1.271), students without myopia (OR=1.121, 95%CI: 1.008-1.248), and students with sufficient sleep (OR=1.162, 95%CI: 1.054-1.281) had a higher risk of excessive recreational use of electronic products. Conclusion The prevalence of excessive recreational use of electronic products among high school students in Shanxi Province was relatively high, which was related to gender, grade, parental education, parental attitudes, boarding status, myopia and sleep quality.

Objective To investigate air radioactivity contamination, surface contamination, ambient dose equivalent rates, and radiation doses to individuals in the treatment room during ¹⁷⁷Lu-DOTATATE therapy. Methods A ward for ¹⁷⁷Lu-DOTATATE therapy was selected in the nuclear medicine department of a general hospital. Air and surface radioactivity samples were collected before and after therapy for four patients. Ambient dose equivalent rates were measured around the four patients following the initiation of ¹⁷⁷Lu-DOTATATE therapy. Measurements were taken at distances of 0.1, 0.3, 0.5, and 1−4 m (with 0.5 m intervals) from the right lateral midsection of the patient’s torso. The measurement time points included 5, 15, and 30 min after initiation of administration, as well as 0−4 h (with 1 h intervals), 24 h, and 48 h post-administration. Radiation exposure doses for personnel at different distances from the patients were calculated for each time interval. Results The results of radioactive aerosol detection for all four patients during and after the administration of ¹⁷⁷Lu-DOTATATE were similar to those before administration. Surface contamination was not detected at the measurement locations except for patient number 2. The ambient dose equivalent rates increased with increasing injection dose during the administration. However, the ambient dose equivalent rates decreased significantly within one hour after administration. At the end of the administration, the average ambient dose equivalent rate at a distance of one meter for the four patients was 42.931 μSv/h. From the start of administration to four hours post-administration, personnel maintaining a distance of one meter from the patient received a total radiation dose of 167.64 μSv. Conclusion Air radioactivity contamination does not occur during ¹⁷⁷Lu-DOTATATE therapy. However, measures should be taken before the commencement of therapy to address potential surface contamination. Both accompanying persons and healthcare staff receive radiation doses below the stipulated dose constraints throughout the treatment process. Therefore, it is necessary to implement appropriate measures to minimize the radiation exposure of healthcare staff.

Objective:To investigate the clinical value of abdominal adipose volume in predicting early tumor recurrence after resection of hepatocellular carcinoma (HCC).Methods:The retrospective case-control study was conducted. The clinicopathological data of 132 HCC patients with tumor diameter ≤5 cm who were admitted to The First Affiliated Hospital of Army Medical University from December 2017 to October 2019 were collected. There were 110 males and 22 females, aged (51±4)years. All patients underwent resection of HCC. Preoperative computer tomography scanning was performed and the visceral and subcutaneous fats of patients were quantified using the Mimics Research 21.0 software. Based on time to postoperative tumor recurrence patients were divided to two categories: early recurrence and non-early recurrence. Observation indicators: (1) consistency analy-sis; (2) analysis of factors influencing early tumor recurrence after resection of HCC and construction of prediction model. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribu-tion were represented as M( Q1,Q3) or M(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were expressed as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Consistency analysis was conducted using the intragroup correlation coefficient (ICC) test. Multivariate analysis was performed using the binary Logistic regression model forward method. Independent risk factors influencing early tumor recurrence after resection of HCC were screened. The area under curve (AUC) of receiver operating characteristic (ROC) curve was applied to select the optimal cut-off value to classify high and low risks of recurrence. The Kaplan-Meier method was used to draw survival curve and calculate survival time. The Log-Rank test was used for survival analysis. Results:(1) Consistency analysis. The consistency ICC of abdominal fat parameters of visceral fat volume (VFV), subcutaneous fat volume, visceral fat area, and subcutaneous fat area measured by 2 radiologists were 0.84, 1.00, 0.86, and 0.94, respectively. (2) Analysis of factors influencing early tumor recurr-ence after resection of HCC and construction of prediction model. All 132 patients were followed up after surgery for 662(range, 292-1 111)days. During the follow-up, there were 52 patients with non-early recurrence and 80 patients with early recurrence. Results of multivariate analysis showed that VFV was an independent factor influencing early tumor recurrence after resection of HCC ( odds ratio=4.07, 95% confidence interval as 2.27-7.27, P<0.05). The AUC of ROC curve based on VFV was 0.78 (95% confidence interval as 0.70-0.85), and the sensitivity and specificity were 72.2 % and 77.4 %, respectively. The optimal cut-off value of VFV was 1.255 dm 3, and all 132 patients were divided into the high-risk early postoperative recurrence group of 69 cases with VFV >1.255 dm 3, and the low-risk early postoperative recurrence group of 63 cases with VFV ≤1.255 dm 3. The disease-free survival time of the high-risk early postoperative recurrence group and the low-risk early post-operative recurrence group were 414(193,702)days and 1 047(620,1 219)days, showing a significant difference between them ( χ2=31.17, P<0.05). Conclusions:VFV is an independent factor influen-cing early tumor recurrence of HCC after resection. As a quantitative indicator of abdominal fat, it can predict the prognosis of HCC patients.

Background and objective Lung adenocarcinoma(LUAD)is a highly morbid and fatal cancer.De-spite advancements in modern medical treatment,the 5-year survival rate of patients remains suboptimal.Our previous study revealed that zinc finger SWIM-type containing 1(ZSWIM1),a novel protein,promotes the proliferation,migration,and inva-sion of LUAD cells.The aim of this study is to investigate the impact ofE3 ubiquitin ligase tripartite motif protein 21(TRIM21)on ZSWIM1-mediated cell proliferation and migration.Methods The interaction and co-localization between TRIM21 and ZSWIM1 were verified using co-immunoprecipitation(Co-IP)and immunofluorescence(IF).The effects of TRIM21 and ZSWIM1 on the proliferation and migration of LUAD cells were assessed through MTT and Transwell assays,respectively.Western blot(WB)analysis was conducted to evaluate the impact of TRIM21 and ZSWIM1 on the expression of epithelial-mesenchymal transition(EMT)markers in LUAD cells.The influence of TRIM21 on the ubiquitination of ZSWIM1 was exam-ined using Co-IP combined with WB.Results TRIM21 was found to interact and co-localize with ZSWIM1.Overexpression of TRIM21 inhibited the proliferation and migration of LUAD cells.Overexpression of TRIM21 reduced the promoting effect of ZSWIM1 on the proliferation,migration,and invasion of lung adenocarcinoma cells,and reversed the impact of ZSWIM1 on the expression of E-cadherin and Vimentin.Conversely,knockdown of TRIM21 further enhanced the promoting effect of ZSWIM1 on the proliferation and migration of LUAD cells.Mechanistically,we observed that overexpression of TRIM21 significantly en-hanced the ubiquitination level of ZSWIM1,leading to a decrease in ZSWIM1 protein expression.Conclusion TRIM21 binds to and promotes the ubiquitination of ZSWIM1,resulting in reduced protein expression of ZSWIM1,which leads to the inhibition of ZSWIM1-mediated promotion of proliferation,migration,and invasion in LUAD cells.

Objective To investigate the effect of early combined use of liraglutide on cardiometa-bolic risk factors and prognosis in patients with T2DM and CMVD.Methods A total of 124 T2DM patients with concomitant CMVD admitted in our hospital from May 2021 to June 2023 were enrolled,and divided into the liraglutide group(n=59)and the non-liraglutide group(n=65)according to taking liraglutide or not.The main observation indicators were compared between the two groups,including cardiometabolic risk factors,such as Hcy,UA,FPG,eGFR,HbA1c,hs-CRP,WC,BMI,WWI,and echocardiographic indicators,such as LAD,LVEDD,LVPWT,IVST,E/e',e',LVEF,LAVI,LVMI,and RWT.And the incidence of adverse reactions and read-mission rates were recorded during follow-up.Results After treatment,in the liraglutide group,Hcy,UA,FPG,HbA1c,hs-CRP,WC,BMI,WWI,E/e',LAVI,LVMI,RWT,IVST and LVPWT values,and anteroposterior,transverse and long diameters of left atrium were all lower than before treatment,and eGFR and e'value were increased(P＜0.05,P＜0.01),and no significant difference was seen in LVEF and LVEDD(P＞0.05).The non-liraglutide group obtained lower HbA1c,FPG,BMI,E/e'and LAVI values,and transverse diameter of left atrium,elevated LVPWT and e'value(P＜0.05,P＜0.01),and no obvious changes in Hcy,UA,eGFR,hs-CRP,WC,WWI,BMI,LVEF,LVMI,RWT,LVEDD,IVST,and anteroposterior and long diameters of left atrium when compared with the indicators before treatment(P＞0.05).At the end of the fol-low-up,when compared with the non-liraglutide group,the liraglutide group had more significant decreases in E/e',LAVI,LVMI and RWT values and increase in e'value(P＜0.05,P＜0.01),and higher total effective rates(94.92％vs 72.31％,P＜0.01).What's more,the readmission rate due to adverse cardiovascular events was notably lower in the liraglutide group and the non-liraglutide group(3.39％vs 15.38％,P＜0.05).Conclusion Compared with BMI,WWI may be more sensi-tive in reflecting changes in cardiometabolic risk factors in T2DM patients with CMVD;Early combined application of liraglutide has good efficacy and safety,and exerts multiple cardiovascular protective effects,including reducing cardiometabolic risk factors,improving cardiac diastolic function and renal function,inhibiting chronic inflammation and decreasing the occurrence of ad-verse cardiovascular events in the patients.
