OBJECTIVES: Nasopharyngeal carcinoma is often diagnosed at a late stage due to its concealed location and exhibits marked regional clustering, posing a significant public health challenge in China. This study aims to analyze the disease burden of nasopharyngeal carcinoma in China using the latest 2021 Global Burden of Diseases (GBD) database, providing epidemiological evidence for precise prevention and control of nasopharyngeal carcinoma. METHODS: Age-standardized incidence rate (ASIR), mortality rate, and disability-adjusted life year (DALY) rate were used as indicators of disease burden. Stratified analyses were conducted by age, sex, socio-demographic index (SDI), and relevant risk factors. The autoregressive integrated moving average (ARIMA) model and Bayesian age-period-cohort (BAPC) model were employed to project ASIR trends through 2050. RESULTS: In 2021, China's age-standardized incidence, mortality, and DALY rates of nasopharyngeal carcinoma were 3.4/100 000, 1.5/100 000, and 48.7/100 000, respectively, all higher than the global average. Across all age groups, Chinese males exhibited higher ASIR, mortality, and DALY rates than females. From 1990 to 2021, the disease burden of nasopharyngeal carcinoma in China decreased gradually with rising SDI. The proportion of nasopharyngeal carcinoma burden attributed to alcohol consumption, smoking, and occupational formaldehyde exposure in China exceeded global levels, especially among males. Projections from both models indicate a rising trend in ASIR for males, females, and the general population in China and globally from 2022 to 2050. CONCLUSIONS Over the past 30 years, the disease burden of nasopharyngeal carcinoma in China has decreased with the increasing SDI values but remains higher than the global average. Furthermore, ASIR is projected to increase over the next 30 years. It is imperative for China to enhance healthcare resource allocation for nasopharyngeal carcinoma prevention, diagnosis, and treatment, particularly among high-risk male populations.

Objective:To explore the predictors and reasons for restenosis in patients with Takayasu′s arteritis(TA) involved renal artery after plain old balloon angioplasty(POBA).Methods:The clinical data of 47 TA patients (47) with renal artery admitted to Xuanwu Hospital, Capital Medical University from January 2014 to December 2020 were analyzed, including 12 man and 35 female. The age ranged from 21 to 43 years old, with an average of (28.52±10.78) years old. All patient were diagnosed as TA and underwent POBA. The patients were divided into restenosis group ( n=18) and non-restenosis group ( n=29). The patients were followed up at 1, 3, and 6 months after surgery, and after 6 months, the patients were followed up every 6 months. All patients were followed up from 36 to 108 months.The basic clinical data of the two groups were compared, and the length of stent and residual stenosis were also compared. Measurement data were expressed as ( ± s), and t-test was used for comparison between groups. Counting data were expressed as the number of cases and percentage, and comparison between groups was analyzed using the chi-square test. Multivariate Logistic regression model was used to analyze the independent risk factors of restenosis after balloon dilation, and the OR value and 95% confidence interval were calculated. Logistic regression model was used to analyze the independent risk factors for restenosis after balloon dilation. Results:All patients received POBA and operation was successfully. Restenosis was found in 18 patients, and 29 patients remained normal during the follow-up. The primary patency rate was 61.7%. Multivariate Logistic regression analysis showed that HDL-C and lesion length were the influencing factors of restenosis after POBA in TA of renal artery. The serum HDL-C level was significantly lower and the lesion was significantly longer in restenosis group than in non-restenosis group ( P<0.05). The proportion of residual stenosis>20% was higher in restenosis group than in non-restenosis group ( P>0.05). Conclusion:Serum HDL-C level, lesion length may be may be independent influencing factors of restenosis after plain old balloon angioplasty in TA of the renal artery restenosis.

Objective To investigate the effects of long non-coding RNA FEZ family zinc finger 1 antisense RNA 1(lncRNA FEZF1-AS1)on enhancer of zeste homolog 2(EZH2)in regulation of proliferation,migration,invasion and epithelial-mesenchymal transition(EMT)of pulmonary interstitial cells and its mechanism.Methods The A549 cells human lung adenocarcinoma cell line were divided into control group and model group[model cells were induced into lung interstitial cells after being treated with transforming growth factor β1(TGF-β1)20 ng/mL for 48 h].The protein expression of E-cadherin,N-cadherin and vimentin in each group was detected by Western blot.The expression of lncRNA FEZF1-AS1 and EZH2 in the two groups was detected by RT-qPCR.Cells in the trans-fection group were divided into si NC group,lncRNA FEZF1-AS1+OE vector group and si lncRNA FEZF1-AS1+OE EZH2 group.Cell proliferation was examined by CCK-8 method,cell migration was detected by cell scratch,and cell invasion was detected by Transwell assays.The protein expression of E-cadherin,N-cadherin,vimentin and EZH2 in each group was detected by Western blot.The direct binding effect of FEZF1-AS1 and EZH2 was deter-mined by RNA immuno-precipitation(RIP).Results Compared with the control group,the protein expression level of E-cadherin in the model group was significantly decreased(P＜0.05),and the protein expression of N-cadherin and vimentin was significantly increased(P＜0.05).Compared with the control group,the expression level of lncRNA FEZF1-AS1 and EZH2 genes was significantly increased in the model group(P＜0.05).Compared with si NC group,the proliferation,migration and invasion ability of si lncRNA FEZF1-AS1+OE vector group were decreased,the ex-pression of E-cadherin protein was increased while the expression of N-cadherin,vimentin and EZH2 was decreased(P＜0.05).Compared with si lncRNA FEZF1-AS1+OE vector group,the proliferation,invasion and migration of si lncRNA FEZF1-AS1+OE EZH2 group were increased(P＜0.05).E-cadherin expression was decreased,while N-cad-herin,vimentin and EZH2 expressions were increased(P＜0.05).RIP experiment further confirmed that lncRNA FEZF1-AS1 had direct binding effect with EZH2.Conclusions LncRNA FEZF1-AS1 can promote the proliferation,invasion,metastasis and EMT process of pulmonary fibrosis cells by regulating EZH2.

Objective:To investigate the predictive value of a clinical imaging model based on multi-slice helical computer tomography (MSCT) examination in predicting prognosis of advanced gastric adenocarcinoma.Methods:The retrospective cohort study was conducted. The clinicopatho-logical data of 88 patients with advanced gastric adenocarcinoma who were admitted to the Ningbo Yinzhou No.2 Hospital from January 2019 to January 2021 were collected. There were 62 males and 26 females, aged (60±15)years. All patients underwent preoperative MSCT examination. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were expressed as absolute numbers. Univariate and multivariate analyses were conducted using the Logistic regression model. The receiver opera-ting characteristic curve was used to analyze the predictive efficacy of prognosis, and the area under the curve (AUC), sensitivity, and specificity were calculated. Results:(1) Surgical situations and follow-up. All 88 patients underwent radical gastrectomy for gastric cancer and were diagnosed with advanced gastric adenocarcinoma through postoperative pathological examination. All 88 patients were followed up after surgery for 41(range, 36?48)months, with a 3-year overall survival rate of 69.32%. (2) Analysis of factors affecting the prognosis of advanced gastric adenocarcinoma after radical surgery. Results of multivariate analysis showed that preoperative carcinoembryonic antigen (CEA) and extramural venous invasion (EMVI) were independent factors affecting the prognosis of advanced gastric adenocarcinoma after radical surgery ( odds ratio=1.10, 7.72, 95% confidence interval as 1.01?3.82, 1.42?15.42, P<0.05). (3) Construction and evaluation of predictive model. The AUC of predictive efficacy of prognosis for advanced gastric adenocarcinoma of preoperative CEA and EMVI were 0.90 (95% confidence interval as 0.82?0.97) and 0.80 (95% confidence intervalas 0.71?0.89), respectively, with sensitivity of 85.25% and 78.69% and specificity of 100.00% and 81.48%, respec-tively. A predictive model was constructed by combining preoperative CEA and EMVI based on the results of multivariate analysis, and the AUC of the predictive model was 0.93 (95% confidence interval as 0.87?0.98), with sensitivity and specificity of 86.89% and 96.30%. Conclusions:CEA and EMVI are independent factors affecting the prognosis of advanced gastric adenocarcinoma after radical surgery. The predictive model constructed by combining preoperative CEA and EMVI has good predictive efficacy for patient prognosis.

Objective:To investigate the effects of extracts of Rhizoma Sparganii and Rhizoma Curcumae on cartilage damage in osteoarthritis rats and NADPH oxidase 2 (NOX2)/reactive oxygen species (ROS)/nuclear factor-κB (NF-κB) signaling pathways. Methods:Rats (50 cases) were divided into the sham group, and model group, as well as the low, medium, and high dose groups of extracts of Rhizoma Sparganii and Rhizoma Curcumae, with 10 rats in each group. Except for sham group, the rat model of cartilage damage in knee osteoarthritis was established. On the second day after modeling, the rats in the low, medium, and high dose groups received intragastric extracts perfusion of Rhizoma Sparganii and Rhizoma Curcumae at the doses of 5, 10, and 20 g/kg respectively. The rats in the sham and model groups received intragastric equivalent 0.9% sodium chloride solution perfusion, once daily, for 20 days by continuous administration. The knee joint behavior, bone metabolism indicators, serum superoxide dismutase (SOD), malondialdehyde (MDA), glutathione (GSH) levels, inflammatory factors, NOX2, and NF-κB levels of each group were observed. Results:Compared with the model group, the behavioral abnormality scores, cartilage oligomeric matrix protein (COMP), MDA, interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), NOX2, and NF-κB levels in the low, medium, and high dose groups were all gradually decreased (all P < 0.05), while proteoglycan, SOD, GSH, and interleukin-10 (IL-10) levels in the low, medium, and high dose groups were all gradually increased (all P < 0.05), and it was dose-dependent. Conclusions:Rhizoma Sparganii and Rhizoma Curcumae extracts can effectively improve cartilage damage in osteoarthritis rats, and it may be related to the inhibition of the NOX2/ROS/NF-κB signaling pathway.

Objective:To explore the therapeutic effect of interventional treatment on Takayasu arteritis involved renal artery.Methods:A retrospective analysis was conducted on the clinical data of 26 patients (28 blood vessels) with Takayasu arteritis involved renal artery admitted to the Xuanwu Hospital, Capital University of Medical Sciences from January 2012 to July 2023. Balloon dilation or stent implantation were performed, and the t vascular patency rate, blood pressure changes, surgical effects, and complications were followed up and observed.Results:All patients underwent balloon dilation or stent implantation, and the surgery was successful, including 23 cases of balloon dilation (25 blood vessels) and 3 cases of stent implantation (3 blood vessels). During the follow-up period of 12-102 months, one case died of renal failure at 57 months post surgery (unilateral renal artery balloon dilation case), and one case was lost in the first year (unilateral renal artery balloon dilation case). The patency rates of balloon dilated blood vessels at 1 year, 3 years, and 5 years were 23/24(95.83%), 22/24(91.67%), and 20/23(86.96%), respectively. Patients with stent implantation had 2 diseased blood vessels unobstructed at 1 year of follow-up and 1 diseased blood vessel unobstructed at 3 years of follow-up. Some patients showed improvement in clinical symptoms, including 3 cases (3/26, 11.54%) of cured hypertension symptoms, 19 cases (19/26, 73.08%) of improved symptoms, and 4 cases (4/26, 15.38%) of ineffective symptoms. The systolic blood pressure decreased from preoperative (169.29±10.76)mmHg to (150.31±14.62)mmHg, with a statistically significant difference ( P<0.05). There was no statistically significant difference in blood creatinine levels between preoperative (78.42±21.38)μmol/L and postoperative (77.83±21.14)μmol/L ( P>0.05). Conclusions:Endovascular angioplasty is safe, feasible, and has a definite therapeutic effect on patients with Takayasu′s arteritis involved renal artery.

Objective To investigate the impact of different treatment options on lumbar function, pain intensity, and anterior vertebral height in elderly patients with thoracolumbar vertebral compression fractures. Methods The clinical data of 102 elderly patients with thoracolumbar vertebral compression fractures who completed 1-year follow-up were retrospectively analyzed. They were divided into conservative group (32 cases), percutaneous kyphoplasty (PKP) group (35 cases), and percutaneous vertebroplasty (PVP) group (35 cases) based on different treatment options. One year after treatment, the clinical efficacy and complications of the three groups were evaluated. The Visual Analogue Scale (VAS) score, Japanese Orthopedic Association (JOA) score, Cobb angle, and anterior vertebral height were compared before and 1 year after treatment among the three groups. Results The excellent and good rates of the PKP group and PVP group were higher than those of the conservative group (P < 0.05). There was no significant difference in the excellent and good rates between the PKP group and PVP group (P>0.05). There was no significant difference in occurrence of complications among the three groups (P>0.05). One year after treatment, the VAS scores of the three groups were lower than before treatment, and the JOA scores were higher than before treatment, and the VAS scores of the PKP group and PVP group were lower than those of the conservative group, and the JOA scores were higher than those of the conservative group (P < 0.05). The VAS score of the PKP group was lower than that of the PVP group, and the JOA score was higher than that of the PVP group (P < 0.05). One year after treatment, the Cobb angles of the three groups were smaller than before treatment, and the anterior vertebral heights were higher than before treatment, and the Cobb angles of the PKP group and PVP group were smaller than those of the conservative group, and the anterior vertebral heights were higher than those of the conservative group (P < 0.05). The Cobb angle of the PKP group was smaller than that of the PVP group, and the anterior vertebral height was higher than that of the PVP group, the difference in anterior vertebral height was greater than that of the PVP group (P < 0.05). Conclusion Compared with conservative treatment, surgery can improve the clinical efficacy of elderly patients with thoracolumbar vertebral compression fractures. PKP is superior to PVP in reducing pain of patients, improving lumbar function and Cobb angle, and anterior vertebral height. Moreover, it has better safety.

To investigate the changes of anesthetic drug concentration in plasma during isolation of autologous blood with acute normovolemic hemodiluti-on and its influence on the depth of anesthesia, muscle relaxant effect and blood drug concentration after reinfusion. METHODS: Forty patients of both sexes, aged 20-60 yr, American Society of Anesthesiologists physical status or Ⅱ, hemoglobin (Hb) >120 g / L, hematocrit (Hct) >35%, undergoing eletive multilevel spinal surgery were included, were divided into 2 groups (n=20 each) using a random number table. ANH group (group A): ANH was performed after stable induction of anesthesia, the target Hct value was 28%-30%, and autologous blood was reinfused after the main operation steps. Control group (group C): routine transfusion and infusion treatment. The bispectral index (BIS) and Train-of-Four stimulation (TOF) were observed and recorded at the stable induction of anesthesia (T1), 30 minutes of stable induction (T2), the end of operation (T3), 30 minutes after the end of the operation (T4), 1 hour after the end of the operation (T5) and 2 hours after the end of the operation (T6). The concentrations of propofol and cisatracurium besylate in plasma at T1-T6, stored blood at 1 h (TS1), 2 h (TS2), and before reinfusion (TS3) were detected by Liquid Chromatography-tandem Mass Spectrometry. The extubation time and recovery score at T4-6 hours were recorded. RESULTS: There was no significant difference in propofol between the two groups at each time point (P > 0.05). The plasma concentration of cisatracurium besylate in group A was higher than that in group C at T3 (P<0.05). The concentration of two kinds of anesthetic drugs in blood samples decreased slightly with time,but there was no significant difference between groups (P>0.05). The BIS value at T4 and TOF value at T3 in group A were significantly lower than those in group C. The recovery score of group A was lower than that of group C at T4 (P<0.05). There was no significant difference in extubation time (P>0.05). CONCLUSION: The plasma concentrations of propofol and cisatracurium besylate were basically unchanged during the in vitro isolation of ANH autologous blood. The plasma concentrations of cisatracurium besylate were only temporarily affected after the main operation steps, but the postoperative muscle relaxation recovery and recovery quality were not significantly affected.

Background:Therapeutic drug monitoring(TDM)has emerged as the important method for managing loss of response to infliximab.The effect of reactive and proactive TDM on clinical outcomes in inflammatory bowel disease(IBD)is uncertain.Aims:To evaluate the effect of proactive and reactive TDM of infliximab on the prognosis of patients with IBD.Methods:Clinical data of 99 IBD patients treated with IFX from January 2017 to October 2021 at the First Affiliated Hospital of Air Force Military Medical University were retrospectively analyzed,including 34 patients with proactive TDM and 65 patients with reactive TDM.The rate of treatment failure,IBD-related surgery or hospitalization were compared between the two groups.Logistic regression analysis was used to determine the independent risk factors of treatment failure.Results:The median follow-up of the patients was 21(13,32)months.The rate of treatment failure,IBD-related hospitalization rate of proactive TDM group were significantly lower than those of reactive TDM group(P<0.05),however,no significant difference in IBD-related surgery rate was found between two groups(P=0.081).Univariate analysis showed that ileocolonic resection before TDM,antibodies to infliximab(ATI)and reactive TDM might be correlated with treatment failure(P<0.05).Logistic regression analysis showed that reactive TDM(OR=5.829,95%CI:1.070-31.754,P=0.042)was the risk factor of treatment failure,and ileocolonic resection before TDM(OR=0.119,95%CI:0.019-0.736,P=0.022)was the protective factor of treatment failure.Conclusions:Compared with reactive TDM group,proactive TDM can significantly decrease the rate of treatment failure and IBD-related hospitalization rate.Reactive TDM is the risk factor of treatment failure,and ileocolonic resection before TDM is the protective factor of treatment failure.

Background Prolonged awkward postures during occupational activities can lead to excessive musculoskeletal load on the wrist of workers and symptoms such as wrist pain or discomfort. Objective To survey the prevalence of wrist pain among workers in 10 key industries and analyze its correlation with wrist working postures. Methods By using stratified cluster sampling method, workers from 10 key industries, such as footwear manufacturing industry, shipbuilding manufacturing industry, and automobile manufacturing industry, were selected from seven regions in North China, East China, Central China, South China, Southwest China, Northwest China, and Northeast China. The demographic information, wrist working postures, pain in wrist of the workers were collected through a cross-sectional survey. Pearson χ² test was used to compare prevalence by selected factors, trend χ² test for between group comparison, and unconditional logistic regression models for the association of wrist working postures with wrist pain. Results There were 64052 workers enrolled in this survey, and 56286 provided valid questionnaires (the effective rate was 87.8%). According to the survey, the prevalence of wrist pain was 23.3% (13112/56286), and the industries with higher prevalences were footwear manufacturing (27.1%, 1927/7106), automobile manufacturing (24.9%, 5378/21560), and shipbuilding and related equipment manufacturing (24.4%, 850/3488) industries. Finger pinching (OR=2.09, 95%CI: 1.95-2.24), frequent wrist bending (OR=2.03, 95%CI: 1.92-2.15), fixed wrist bending (OR=1.77, 95%CI: 1.69-1.85), wrist on hard edge (OR=1.34, 95%CI: 1.28-1.40), and arms over shoulders (OR=1.11, 95%CI: 1.05-1.17) increased the risk of reporting wrist pain. Conclusion Awkward postures are related to wrist pain among workers in selected 10 key industries. The related factors are wrist on hard edge, frequent wrist bending, finger pinching, fixed wrist bending, and arms over shoulders.
