Objective To analyze the temporal trend of thyroid cancer incidence in China from 1992 to 2021 and evaluate the impact of age,period and cohort on the incidence.Methods Based on the Global Burden of Disease 2021,the trend changes of age-standardized incidence rate(ASIR)of thyroid cancer in China from the period were analyzed,and the obtained data were further analyzed with Joinpoint regression and age-period-cohort analysis.Auto regressive integrated moving average(ARIMA)model was applied to predict the incidence of thyroid cancer in China in the next 20 years.Results The ASIR of thyroid cancer among males was increased from 0.70/100 000 to 2.11/100 000 between 1992 and 2021,with an average annual percent change(AAPC)of 3.93%(95%CI:3.86%～4.00%,P<0.001);For the females,the ASIR was elevated from 1.91/100 000 to 2.87/100 000 in the time,with an AAPC of 1.43%(95%CI:1.36%～1.50%,P<0.001).On the age effect,the overall variation in ASIR among the females was minor,and that in the males reached its peak in the≥85-years-old group,with a rate of 230.51/100 000.Regarding the period effect,the risk of thyroid cancer incidence in the males and females changed with the period and exhibited a temporal increase,and the incidence risk was consistently higher in the males than the females across different periods.Taking the incidence risk during 1992 and 1996 as a reference(RR=1),the males(RR=2.94,95%CI:2.78～3.11)and the females(RR=1.37,95%CI:1.32～1.42)had the highest risk of thyroid cancer in the period from 2017 to 2021.On the cohort effect,the risk of thyroid cancer in both sexes showed an increasing trend with cohort change.When taking the cohort during 1992 and 1996 as a reference(RR=1),the females in the pre-1986 cohort exhibited a higher risk of incidence than the males,but in the post-1996 cohort,the males demonstrated a greater risk of incidence than the females.The males in the 2012-2016 cohort had the highest risk of thyroid cancer when compared to the reference group(RR=2.54,95%CI:1.80～3.57),and the females in the cohort from 1992 to 2016 had higher risk of thyroid cancer than the reference group,though no statistical differences were observed.The ARIMA model prediction analysis found that the ASIR of thyroid cancer in males and females in China would continue to increase from 2022 to 2041,and the ASIR of thyroid cancer in males would reach 2.79/100 000(95%CI:1.96～3.61),and the ASIR of thyroid cancer in females would reach 3.54/100 000(95%CI:3.02～4.06)by 2041.Conclusion Between 1992 and 2021,the ASIR of thyroid cancer in China has exhibited a consistent upward trend,with the females having a higher ASIR than the males.However,the risk of developing thyroid cancer is higher in men who are older and those who were born more recently.In the next 20 years,the incidence of thyroid cancer among both men and women in China is projected to continue to rise,and the situation for prevention and control will be challenging.

ObjectiveTo investigate the role and possible mechanism of action of rhubarb decoction （RD） retention enema in improving inflammatory damage of brain tissue in a rat model of mild hepatic encephalopathy （MHE）. MethodsA total of 60 male Sprague-Dawley rats were divided into blank group （CON group with 6 rats） and chronic liver cirrhosis modeling group with 54 rats using the complete randomization method. After 12 weeks， 40 rats with successful modeling which were confirmed to meet the requirements for MHE model by the Morris water maze test were randomly divided into model group （MOD group）， lactulose group （LT group）， low-dose RD group （RD1 group）， middle-dose RD group （RD2 group）， and high-dose RD group （RD3 group）， with 8 rats in each group. The rats in the CON group and the MOD group were given retention enema with 2 mL of normal saline once a day； the rats in the LT group were given retention enema with 2 mL of lactulose at a dose of 22.5% once a day； the rats in the RD1， RD2， and RD3 groups were given retention enema with 2 mL RD at a dose of 2.5， 5.0， and 7.5 g/kg， respectively， once a day. After 10 days of treatment， the Morris water maze test was performed to analyze the spatial learning and memory abilities of rats. The rats were analyzed from the following aspects： behavioral status； the serum levels of alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， interleukin-1β （IL-1β）， interleukin-6 （IL-6）， and tumor necrosis factor-α （TNF-α） and the level of blood ammonia； pathological changes of liver tissue and brain tissue； the mRNA and protein expression levels of phosphatidylinositol 3-kinase （PI3K）， protein kinase B （AKT）， and mammalian target of rapamycin （mTOR） in brain tissue. A one-way analysis of variance was used for comparison of continuous data between multiple groups， and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the MOD group， the RD1， RD2， and RD3 groups had a significantly shorter escape latency （all P<0.01）， significant reductions in the levels of ALT， AST， IL-1β， IL-6， TNF-α， and blood ammonia （all P<0.05）， significant alleviation of the degeneration， necrosis， and inflammation of hepatocytes and brain cells， and significant reductions in the mRNA and protein expression levels of PI3K， AKT， and mTOR in brain tissue （all P<0.05）， and the RD3 group had a better treatment outcome than the RD1 and RD2 groups. ConclusionRetention enema with RD can improve cognitive function and inflammatory damage of brain tissue in MHE rats， possibly by regulating the PI3K/AKT/mTOR signaling pathway.

Objective To analyze coating properties of porous artificial joints,including coating morphology and coating mechanical properties,and summarize the range of coating properties of current mainstream products,to provide references for the design and development of new products,as well as provide the basis for the long-term implant removal analysis.Methods Samples for the surface morphology,shear strength,and tensile strength of the coatings used in the experiment were prepared in accordance with ASTM F1854,ASTM F1044,and ASTM F1 147 standards,respectively.The coatings were processed using plasma spraying.The surface morphology(coating thickness,porosity,and pore intercept)of the coatings for all 17 products(Nos.1-17)was tested;for products Nos.1-7 and Nos.15-16,the shear strength test between the coating and substrate was conducted first in accordance with the test method of ASTM F1044.Then,according to the test method of ASTM F1 147,the tensile strength test between the coating and substrate was conducted.For product No.17,the shear and tensile strengths of the composite coating and simple titanium coating were tested,respectively,according to the test method of ASTM F1044 and ASTM F1 147.Results A total of 15 products(88.2％)had coating thicknesses between 300 μm and 500 μm.There were 16 metal-coated products(Nos.1-16),of which 11(68.75％of the total)had coating porosities between 30％and 50％,and 14(87.5％of the total)had coating pore intercepts between 50 μm and 150 μm.The mechanical properties of the coatings were independent of the substrate material used.The shear and tensile strengths of the composite coatings with hydroxyaptite(HA)were significantly lower than those of the pure metal coatings.Conclusions For the design and manufacture of artificial joints with porous coatings,the performance of the coating can be referred to the following indexes:the coating thickness is 300-500 μm,the coating porosity is 30％-50％,the coating pore intercept is 50-150 μm.The substrate materials can be selected based on the use of the product.The effects of a lower bonding force on product performance should be considered when designing prostheses with composite coatings containing HA.This range of performance metrics provides control for long-term clinical extraction analyses.

Objective To explore the relationship between lipoprotein(a)[Lp(a)],fibrinogen(Fib)levels and vascular calcification and severity of autogenous arteriovenous fistula(AVF)in maintenance hemodialysis(MHD)patients.Methods A total of 112 MHD patients who visited Suining Central Hospital from November 2021 to November 2023 were selected as the study subjects.According to the degree of AVF vascular calcification,these patients were divided into a non calcified group(n=45)and a calcified group(n=67),in which the calcified group was divided into a mild calcification group(n=19),a moderate calcification group(n=28)and a severe calcification group(n=20).The general information and Lp(a)and Fib levels between non calcified group and calcified group were compared.Multivariate logistic regression model was used to determine the independent risk predictors of AVF vascular calcification in MHD patients.Clinical data of patients with different degrees of calcification were compared.Generalized mixed effects model was used to analyze the relationship between Lp(a),Fib levels and the degree of AVF vascular calcification in MHD patients.Restricted cubic spline model was used to analyze the dose-response relationship between Lp(a)and Fib and severe vascular calcification in AVF.The interaction between Lp(a)and Fib on the severity of vascular calcification in AVF was analyzed.Results Dialysis time,P,PTH,Scr,Hb,BMP-2,FGF-21,Lp(a)and Fib levels of patients in the calcification group were increased(t=17.420,9.640,4.863,6.646,2.158,12.046,13.290,2.395,6.674,all P<0.05),while Ca level was decreased(t=2.820,P=0.006),the differences were statistically significant,respectively.The results of multivariate analysis showed that dialysis time(OR:3.130,95%CI:1.652～5.931),P(OR:4.760,95%CI:2.103～7.133),PTH(OR:3.314,95%CI:1.062～6.045),Scr(OR:2.288,95%CI:1.168～4.481),Hb(OR:4.616,95%CI:2.384～7.949),BMP-2(OR:5.527,95%CI:2.598～9.212),FGF-21(OR:6.242,95%CI:1.201～11.184),Lp(a)(OR:5.509,95%CI:2.787～10.886)and Fib(OR:6.159,95%CI:2.125～12.140)were all independent risk factors for AVF vascular calcification in MHD patients(all P<0.05).There were statistically significant in dialysis time,Ca,PTH,Scr,Hb,BMP-2,FGF-21,Lp(a)and Fib levels among the three groups(F=2.028～6.324,all P<0.05).Patients in the severe calcification group had higher dialysis time,PTH,Scr,Hb,BMP-2,FGF-21,Lp(a)and Fib levels than those in the mild calcification group(t=2.204～11.064)and the moderate calcification group(t=2.025～3.197),while Ca level was reduced(t=3.121,2.471),with statisitcally significant differences(all P<0.05),respectively.The results of the generalized mixed effects model showed that the levels of Lp(a)and Fib were related to the degree of AVF vascular calcification in MHD patients.The results of the restricted cubic spline model showed a non-linear dose-response relationship between Lp(a)and Fib levels and severe vascular calcification in AVF.There was an interactive effect between serum Lp(a)and Fib levels on the severity vascular calcification in AVF(OR=6.324,2.534,all P<0.05).Conclusion Lp(a)and Fib have a certain correlation with the degree of vascular calcification in patients,which may be influencing factors of autogenous AVF vascular calcification in MHD patients.

Background: Excessive growth of keratinocytes is the critical event in the etiology of psoriasis.However, the underlying molecular mechanism of psoriatic keratinocyte hyperproliferation is still unclear. Objective: This study aimed to figure out the potential contributory role of S-phase kinase-associated protein 2 (SKP2) in promoting the hyperproliferation of keratinocytes in psoriasis. Methods: We analyzed microarray data (GSE41662) to investigate the gene expression of SKP2in psoriatic lesion skins compared with their adjacent non-lesional skin. Then, we further confirmed the mRNA and protein expression of SKP2 in human psoriatic skin tissues, imiquimod (IMQ)-induced psoriatic mice back skins and tumor necrosis factor α (TNF-α), interleukin (IL)-17A and IL-6-stimulated keratinocytes by using real-time quantitative polymerase chain reaction and western blot (WB). Furthermore, we explored the potential pathogenic role and its underlying cellular mechanism of SKP2 in promoting keratinocytes hyperproliferation through 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, cell cycle detection, 5-ethynyl-2′-deoxyuridine staining and WB. Finally, we determined whether inhibition of SKP2 can effectively alleviate the keratinocytes hyperproliferation in vivo. Results: We identified that SKP2 is aberrantly upregulated in the psoriatic lesion skin and cytokines-stimulated keratinocytes. Moreover, upregulated SKP2 augments cytokines-induced keratinocytes hyperproliferation. Mechanistically, enhanced SKP2 increased the S phase ratio through inhibiting Cyclin-Dependent Kinase Inhibitor p27 (P27 Kip1) expression. Correspondingly, suppression of SKP2 with SMIP004 can significantly ease the epidermis hyperplasia in vivo. Conclusion Our results suggest that elevated SKP2 can empower keratinocytes proliferation and psoriasis-like epidermis hyperplasia via downregulation of P27 Kip1. Therefore, targeting SKP2-P27 Kip1 axis might be a promising therapeutic strategy for the treatment of psoriasis in future.

Pulmonary blast injury has become the main type of trauma in modern warfare, characterized by externally mild injuries but internally severe injuries, rapid disease progression, and a high rate of early death. The injury is complicated in clinical practice, often with multiple and compound injuries. Currently, there is a lack of effective protective materials, accurate injury detection instrument and portable monitoring and transportation equipment, standardized clinical treatment guidelines in various medical centers, and evidence-based guidelines at home and abroad, resulting in a high mortality in clinlcal practice. Therefore, the Trauma Branch of Chinese Medical Association and the Editorial Committee of Chinese Journal of Trauma organized military and civilian experts in related fields such as thoracic surgery and traumatic surgery to jointly develop the Clinical treatment guideline for pulmonary blast injury ( version 2023) by combining evidence for effectiveness and clinical first-line treatment experience. This guideline provided 16 recommended opinions surrounding definition, characteristics, pre-hospital diagnosis and treatment, and in-hospital treatment of pulmonary blast injury, hoping to provide a basis for the clinical treatment in hospitals at different levels.

Objective:To compare the efficacy and prognostic evaluation of response evaluation criteria in lymphoma (RECIL) and Lugano classification in patients with 18F-FDG-avid Hodgkin′s lymphoma (HL) and non-HL (NHL) during mid-chemotherapy. Methods:From January 2015 to August 2021, 240 patients (149 males and 91 females, age 50.0(32.0, 62.0) years) with pathologically confirmed lymphoma in Shanxi Cancer Hospital were retrospectively analyzed. Pre-treatment and mid-treatment 18F-FDG PET/CT examinations were performed, and the differences of PET/CT imaging results among patients with different types of lymphoma were analyzed ( χ2 test or Kruskal-Wallis rank sum test). Efficacy evaluation was conducted during mid-chemotherapy, and the results were divided into complete remission (CR), partial remission (PR), stable disease (SD), progressive disease (PD) according to Lugano classification, which were divided into CR, PR, mild remission (MiR), SD, PD according to RECIL. For the better comparison with Lugano classification, MiR was included in PR group (recorded as RECIL-1) and SD group (recorded as RECIL-2) in this study. All patients were followed up, and the progression free survival (PFS) was analyzed. Kappa test, χ2 test or Fisher exact probability method were used to analyze the data, and ROC curve was used to compare the prediction efficiency of different standards. Results:Among 240 patients with different types of lymphoma (96 HL, 30 follicular lymphoma (FL), 114 diffuse large B-cell lymphoma (DLBCL)), there were statistically significant differences in baseline SUV max ( H=54.96, P<0.001) and the sum of longest diameters ( H=15.85, P<0.001). Patients were followed up for 12-89 months, and 26 patients (10.8%) were evaluated as MiR according to the RECIL. The consistency ( Kappa) was 0.84 between results of RECIL-1 and Lugano classification, which was 0.74 between RECIL-2 and Lugano classification (both P<0.001). According to Lugano classification, the PFS rates of patients evaluated as CR, PR, SD and PD were 91.4%(148/162), 57.1%(36/63), 1/3 and 3/12 respectively, which were 91.3%(136/149), 62.8%(49/78), 1/2 and 2/11 for RECIL-1, and 91.3%(136/149), 57.7%(30/52), 71.4%(20/28) and 2/11 for RECIL-2 respectively ( χ2 values: 46.64-52.44, all P<0.001). The AUC of Lugano classification for predicting PFS had a trend to be higher than AUCs of RECIL-1 and RECIL-2 (0.774, 0.758 and 0.746; z values: 1.28, 1.61, P values: 0.200, 0.107). Conclusion:RECIL and Lugano classification have similar efficacy and prognostic evaluation effect on patients with 18F-FDG-avid HL and NHL during mid-chemotherapy.

Objective:To investigate the association between metabolic syndrome and the risk of early renal function injury in chronic kidney disease(CKD) in the elderly.Methods:A retrospective cohort was established based on health check-up data of 4 495 elderly residents in Mengzi City, Yunnan Province from January 2016 to December 2018. The medial history, living habits, and related physical examination information were collected. Cox hazard regression model was used to explore the association between metabolic syndrome, along with its components, and the early renal function injury in CKD. Results:The median age of the elderly was 71.00(67.00, 75.00) years, with metabolic syndrome detection rate of 21.98%. Early renal function injury of CKD developed in 1 300(28.92%) subjects during the follow-up. Univariate Cox regression showed that the number of metabolic syndrome components was associated with the risk of early kidney development in CKD. The HRs were 1.23 (95% CI 1.03-1.47, P=0.022) with 1 component, 1.54 (95% CI 1.28-1.84, P<0.001) with 2, and 1.38 (95% CI 1.14-1.67, P<0.001) with 3 or more. Multivariate Cox regression showed that elevated fasting triglycerides( HR=1.20, 95% CI 1.07-1.36, P=0.003) and lower high density lipoprotein-cholesterol(HDL-C; HR=1.25, 95% CI 1.09-1.43, P=0.002) were risk factors for early kidney injury in CKD, while doing some physical activity( HR=0.57, 95% CI 0.33-0.98, P=0.042), or on daily basis( HR=0.57, 95% CI 0.49-0.66, P<0.001) was a protective factor for early kidney injury in CKD. Conclusion:The abnormality of one or more metabolic components can significantly increase the risk of early kidney injury in the elderly with CKD. Elevated triglyceride and decreased HDL-C may be the risk factors.

Objective:To understand the research hotspots and development trends of oncology nurses at home and abroad from 2011 to 2020, so as to provide reference for related research.Methods:The articles related to oncology nurses at home and abroad from 2011 to 2020 were retrieved through China National Knowledge Infrastructure database, Web of Science database and PUBMED database, and the included literatures′ published journals, institutions and keywords were analyzed by using the online analysis of Statistical Analysis Toolkit for Informetrics3.2 and the software CiteSpace5.7.R1.Results:A total of 588 domestic and 738 foreign articles were included. Keywords analysis showed that domestic oncology nurse related research hotspots were occupational evaluation, hospice care, psychology and occupational protection. Oncology nurse at home and abroad research hotspots had both similarities and differences, different in fertility preservation, communication and so on.Conclusions:The domestic core journal forums of oncology nurse research are still too scattered, and there is a certain gap in the number of articles published between our country and other countries. China still needs to increase the research efforts in this field.
