[Objective] To explore the relationship between neutrophil activation under cardiopulmonary bypass (CPB) and the incidence of cardiac surgery-associated acute kidney injury (CS-AKI). [Methods] This prospective cohort study enrolled adult patients who scheduled for cardiac surgery under CPB at West China Hospital between May 1, 2022 and March 31, 2023. The primary outcome was acute kidney injury (AKI). Blood samples (5 mL) were obtained from the central vein before surgery, at rewarming, at the end of CPB, and 24 hours after surgery. Neutrophils were labeled with CD11b, CD54 and other markers. To assess the effect of neutrophils activation on AKI, propensity score matching (PSM) was employed to equilibrate covariates between the groups. [Results] A total of 120 patients included into the study, and 17 (14.2%) developed AKI. Both CD11b⁺ and CD54⁺ neutrophils significantly increased during the rewarming phase and the increases were kept until 24 hours after surgery. During rewarming, the numbers of CD11b⁺ neutrophils were significantly higher in AKI compared to non-AKI (4.71×10⁹/L vs 3.31×10⁹/L, Z=-2.14, P<0.05). Similarly, the CD54⁺ neutrophils counts were also significantly higher in AKI than in non-AKI before surgery (2.75×10⁹/L vs 1.79×10⁹/L, Z=-2.99, P<0.05), during rewarming (3.12×10⁹/L vs 1.62×10⁹/L, Z=-4.34, P<0.05), and at the end of CPB (4.28×10⁹/L vs 2.14×10⁹/L, Z=-3.91, P<0.05). An analysis of 32 matched patients (16 in each group) revealed that CD11b⁺ and CD54⁺ neutrophil levels of AKI were 1.74 folds (4.83×10⁹/L vs 2.77×10⁹/L, Z=-2.72, P<0.05) and 2.34 folds (3.32×10⁹/L vs 1.42×10⁹/L, Z=-4.12, P<0.05), respectively, of non-AKI at rewarming phase. [Conclusion] Neutrophils are activated during CPB, and they can be identified by CD11b/CD54 markers. The activated neutrophils of AKI patients are approximately 2 folds of non-AKI during the rewarming phase, with disparity reached peak between groups during rewarming. These findings suggest the removal of 50% of activated neutrophils during the rewarming phase may be effective to reduce the risk of AKI.

Objective: To explore the association between mediterranean diet (MD) patterns and dental caries among children and adolescents with neurodevelopmental disorders (NDD), so as to provide a basis for developing scientific anti caries strategies related to diet. Methods: From December 2021 to June 2024, a questionnaire survey, a three day 24 hour dietary review survey, oral health examination, physical development measurement and Childhood Autism Rating Scale (CARS) evaluation were conducted involving 147 children and adolescents aged 2-22 years with NDD from nine special education schools and rehabilitation institutions in Tianjin. Group comparisons were carried out using the Mann-Whitney U test, Chi-square test, or Fisher s exact probability method. The correlation between dietary quality and dental caries was analyzed by adopting multiple linear regression analysis and restricted cubic spline. Results: There were 46 children and adolescents (31.3%) in the non dental caries group and 101 children and adolescents (68.7%) in the dental caries group. The number of decayed missing and filled teeth (dmft) was 2.0 (4.0), and the MD score was 4.0 (2.0) points. There were 62 children and adolescents (42.2%) in the low MD scores group and 85 children and adolescents (57.8%) in the high MD scores group. There was no significant difference in MD scores between NDD children in the non dental caries group and those in the dental caries group [nondental caries group:4.0(2.0), dental caries group:4.0(2.0), Z= -0.14, P >0.05]. The MD scores and dmft exhibited increasing and then decreasing trend ( P total =0.02, P non lineary = 0.04 ). Children and adolescents with NDD in the MD high scores group had a lower number of dmft than those in the MD low scores group ( β= -2.00 , 95%CI =-3.39 to -0.62, P <0.05). However, in children and adolescents with NDD and CARS scores ≥30, the above association was insignificant ( β=-0.63, 95%CI=-0.29-0.15, P >0.05). Conclusion Children and adolescents with NDD who have dietary patterns similar to the Mediterranean diet, are found to have fewer dental caries, and this is observed among those with no or mild symptoms of autism spectrum disorder.

ObjectiveTo explore the potential mechanism of Erchen Decoction （二陈汤， ECD） in improving metabolic syndrome （MS） with phlegm syndrome. MethodsForty mice were randomly divided into a blank group of 10 mice and a modeling group of 30 mice. The MS model with phlegm syndrome was induced in the modeling group by high-fat diet. Thirty successfully modeled mice were randomly divided into a model group， a ECD group， and a metformin group， with 10 mice in each group. The ECD group was given 0.4 g/（kg·d） of ECD， while the metformin group was intervened with 11.1 g/（kg·d） of metformin solution， and the blank group and the model group were given 0.02 ml/（g·d） of sterilized drinking water， all by gavage， once daily for 4 weeks. Body weight， abdominal circumfe-rence， body length， Lee's index and food intake were recorded. Blood glucose and blood lipid levels including fasting blood glucose， triglycerides （TG）， total cholesterol （TC）， high-density lipoprotein cholesterol （HDL-C）， and low-density lipoprotein cholesterol （LDL-C） were measured. ELISA was used to detect serum leptin levels， while HE staining was used to observe liver pathological changes. Western Blot and q-PCR were used to detect protein and mRNA expression of hypothalamic leptin receptor （LepR）， pro melanocortin （POMC）， and neuropeptide Y （NPY） in the hypothalamus. Immunofluorescence was used to detect fluorescence expression of POMC and NPY in the hypothalamic arcuate nucleus region. ResultsPathological results showed that the mice in the model group had numerous fat vacuoles in hepatocytes and significant liver fat deposition， while the ECD and metformin groups showed reduced fat vacuoles and less liver fat deposition. Compared to those in the blank group， the mice in the model group mice showed liver fat deposition， increased body weight， abdominal circumference， Lee's index and food intake； fasting blood glucose， TG， TC， LDL-C， and serum leptin levels were elevated， while HDL-C was decreased； the expression of LepR， POMC protein levels and their mRNA expression decreased， while the protein level and mRNA expression of NPY increased； the fluorescence expression of POMC in the arcuate nucleus was reduced， while NPY fluorescence expression increased （P＜0.05 or P＜0.01）. Compared to the model group， the ECD group and metformin group showed significant improvements in the above indicators （P＜0.05 or P＜0.01）. Compared to the ECD group， the metformin group showed a reduction in body weight and NPY fluorescence expression， and an increase in HDL-C levels （P＜0.05 or P＜0.01）. ConclusionECD can downregulate serum leptin levels and improve glucose and lipid metabolism in the MS of phlegm syndrome. Its mechanism of action may be to reduce liver fat deposition and thereafter affect the expression of neuropeptides related to feeding activity in the hypothalamus.

OBJECTIVE To investigate the correlation between serum levels of asprosin and adropin in elderly patients with obstructive sleep apnea syndrome(OSAS)and the disease severity.METHODS From August 2021 to August 2023,131 elderly OSAS patients admitted to Ezhou Central Hospital were collected as observation subjects(OSAS group),according to the sleep apnea hypopnea index(AHI),there were 40 cases in the mild group,52 cases in the moderate group,and 39 cases in the severe group,meantime,124 healthy individuals who came to health clinic of our hospital for physical examination were collected as the control group.Enzyme-linked immunosorbent assay(ELISA)was applied to determine the levels of asprosin and apropin in the serum of OSAS patients;Pearson method was applied to analyze the correlation between serum asprosin,apropin levels and AHI,ODI,and LSaO2.ROC curve was used to analyze the diagnostic value of serum asprosin and adropin levels in OSAS and the severity of OSAS patients.RESULTS Compared with the control group,the asprosin level in the OSAS group was obviously increased,while the adropin level was obviously reduced(P<0.05).There was no statistically obvious difference in gender,age,coronary heart disease,hypertension,TC,TG,HDL-C,LDL-C among the mild,moderate,and severe groups(P>0.05);compared with the mild group,the levels of BMI,AHI,ODI,and asprosin in the moderate and severe groups were obviously increased,while the levels of LSaO2 and apropin were obviously reduced(P<0.05);compared with the moderate group,the levels of BMI,AHI,ODI,and asprosin in the severe group were obviously increased,while the levels of LSaO2 and apropin were obviously reduced(P<0.05).The serum asprosin level in OSAS patients was positively correlated with AHI and ODI,and negatively correlated with LSaO2(P<0.05);the level of apropin was negatively correlated with AHI and ODI,and positively correlated with LSaO2(P<0.05).The AUC of serum asprosin,apropin levels,and their combination in diagnosing moderate and severe OSAS was 0.832,0.882,and 0.942,respectively,the combined diagnostic value of the two was superior to that of single diagnosis(Z=3.435,2.560,P=0.001,0.011).Serum asprosin,adropin levels and AUC of combined diagnosis of OSAS were 0.818,0.804 and 0.893,respectively.The value of combined diagnosis was better than that of single diagnosis(Z=3.886,4.126,P=0.000,0.000).CONCLUSION The serum level of asprosin is increased and the level of adropin is decreased in patients with OSAS,which is closely related to the severity of the disease,and may be used in the clinical diagnosis of OSAS and the evaluation of the severity of OSAS.

AIM:To explore the roles and associations of hepatocyte nuclear factor 4 alpha(HNF4A)and mu-protocadherin(MUCDHL)in the kidney of diabetic mice.METHODS:(1)A cohort of six 12-week-old db/m mice and six db/db mice were selected and maintained on a standard diet until 16 weeks.The protein levels of fibronectin(FN),collagen type III(Col-III),E-cadherin,α-smooth muscle actin(α-SMA),HNF4A,Snail and MUCDHL in renal tissues were scrutinized using Western blot.Immunohistochemical staining was conducted to observe the distribution and expres-sion of FN,HNF4A and MUCDHL.(2)Mouse renal tubular epithelial cells(mRTEC)were cultured in vitro and catego-rized into groups:normal glucose(NG)group,high glucose(HG)group,overexpression control groups(NG+vector and HG+vector),overexpression groups(NG+OE-MUCDHL,HG+OE-MUCDHL,NG+OE-HNF4A and HG+OE-HNF4A),knockdown control groups(NG+control and HG+control),and knockdown groups(NG+si-MUCDHL,HG+si-MUCDHL,NG+si-HNF4A and HG+si-HNF4A).The relevant protein levels were also detected by Western blot.RESULTS:(1)In db/db group,elevated body weight,blood glucose and urine albumin-to-creatinine ratio(UACR)indicated significant re-nal injury.Compared with db/m group,the mice in db/db group exhibited increased expression of FN,Col-III,α-SMA and Snail,and decreased expression of E-cadherin,HNF4A and MUCDHL.MUCDHL was predominantly expressed in the apical membrane of renal tubular epithelial cells,FN in the tubular mesenchyme,and HNF4A in the plasma and nu-cleus of renal tubular cells.(2)In HG group,there was an up-regulation in the expression of fibrosis-related proteins and a down-regulation in the expression of E-cadherin,HNF4A and MUCDHL compared with NG group.Overexpression of MUCDHL led to a decrease in the expression of FN,Col-III,α-SMA and Snail proteins,an increase in the expression of E-cadherin and MUCDHL proteins,and unaltered expression of HNF4A.Knockdown of MUCDHL resulted in a reversal of the aforementioned effects,with HNF4A expression remaining unaltered.Overexpression of HNF4A led to an increased ex-pression of MUCDHL,and the expression changes of the remaining indicators were consistent with the overexpression of MUCDHL.Knockdown of HNF4A reversed the aforementioned effects.MUCDHL may represent a downstream target gene of HNF4A.CONCLUSION:The diminished expression of HNF4A and MUCDHL in the renal tubules of diabetic mice implies their involvement in the progression of renal fibrosis in diabetic kidney disease(DKD).HNF4A may potentially impede the progression of renal fibrosis in DKD by up-regulating the expression of MUCDHL.

ObjectiveTo observe the clinical efficacy of Tongfu Xiezhuo enema in treating stage 3-4 chronic kidney disease （CKD） and the effect of the therapy on the neutrophil-to-lymphocyte ratio （NLR） as an inflammation marker. MethodSixty patients diagnosed with stage 3-4 CKD who visited the Nephrology Department of the First Affiliated Hospital of Heilongjiang University of Chinese Medicine from December 2022 to June 2023 were included and randomly assigned into observation and control groups in a ratio of 1∶1. The control group received conventional therapy plus Shenkang suppositories， while the observation group received conventional therapy plus Tongfu Xiezhuo enema. After 8 weeks of treatment， the clinical efficacy was assessed based on the changes in traditional Chinese medicine （TCM） symptom scores， renal function indicators， and NLR. Result① Both groups showed decreases in TCM symptom scores after treatment （P<0.01）， and the decreases were more significant in the observation group than in the control group （P<0.05）. The total response rate of TCM symptoms in the observation group was 79.31% （23/29）， which was higher than that （62.96%， 17/27） in the control group （Z=0.604，P<0.05）. ② After treatment， the observation group showed declined serum levels of creatinine （SCr）， blood urea nitrogen （BUN）， and cystatin C （Cys C） and increased glomerular filtration rate （GFR） （P<0.01）， and the control group showed lowered SCr level and increased GFR （P<0.05）. The observation group had lower SCr level and higher GFR than the control group after treatment （P<0.05）. The total response rate of renal function in the observation group was 79.31% （23/29）， which was higher than that （55.56%， 15/27） in the control group （Z=1.127，P<0.01）. ③ The NLR in the observation group decreased after treatment （P<0.05）， and it was lower than that in the control group （P<0.05）. ④ There were no significant differences in safety indicators between the two groups before and after treatment. ConclusionTongfu Xiezhuo enema ameliorated symptoms and improved renal function indicators in the patients with stage 3-4 CKD by reducing the NLR and inhibiting inflammation.

Objective:To investigate the association between gestational blood pressure and neurodevelopment in 2-year-old children.Methods:Based on the"Wuhan Healthy Baby Birth Cohort", 3 754 mother-infant pairs were enrolled in this study. Based on multiple blood pressure measurements during pregnancy, the mean, cumulative, and variability of blood pressure throughout the entire pregnancy and each trimester were calculated. Blood pressure variability was evaluated using standard deviation (SD), coefficient of variability (CV), and variability independent of mean (VIM). Follow-up testing of neurodevelopment in infants and young children at the age of two was conducted to obtain the Mental Development Index (MDI) and the Psychomotor Development Index (PDI). The multivariate linear regression and generalized estimation equation were used to analyze the association between gestational blood pressure data and neurodevelopmental index.Results:The age of 3 754 pregnant women was (29.1±3.6) years, with a pre-pregnancy BMI of (20.9±2.7) kg/m2 and a gestational age of (39.3±1.2) weeks. The birth weight of 3 754 children was (3 330.9±397.7) grams, and the birth length was (50.3±1.6) centimeters. The results of the multivariate linear regression analysis showed that after adjusting for relevant confounding factors, the mean blood pressure, cumulative blood pressure, standard deviation of blood pressure, coefficient of variation of blood pressure, independent blood pressure variability of systolic blood pressure, diastolic blood pressure, and pulse pressure throughout pregnancy were negatively associated with the MDI and PDI scores of 2-year-old children. The analysis results of the generalized estimation equation showed that after adjusting for relevant confounding factors, the average systolic blood pressure in the first, second, and third trimesters was negatively associated with MDI/PDI. The negative association between cumulative blood pressure and MDI/PDI was only found in the first trimester. The negative association between blood pressure variation during pregnancy and MDI/PDI was mainly concentrated in the second and third trimesters.Conclusion:There is a negative association between gestational blood pressure and the neurodevelopmental index of 2-year-old children.

Objective To explore the value of expression levels of serum thioredoxin-interacting protein(TXNIP)and baculoviral IAP repeat-containing protein 5(BIRC5)in clinical staging and efficacy monitoring in patients with primary laryngeal cancer(PLC).Methods From June 2020 to January 2023,a total of 68 pa-tients with PLC accepted by the hospital were collected as PLC group,and 80 patients with benign lesions were set as the benign tumors group.After six months of treatment,patients in the PLC group were separated into the treatment effective group(50 cases)and the treatment ineffective group(18 cases)according to the RECIST solid tumor efficacy evaluation criteria.Enzyme linked immunosorbent assay(ELISA)was applied to detect the levels of TXNIP and BIRC5 in serum of each group;the diagnostic efficacy of TXNIP and BIRC5 in staging PLC and the predictive efficacy of PLC patients were analyzed using the receiver operating characteris-tic(ROC)curve.Results There were statistically significant differences in the expression levels of TXNIP and BIRC5 in the serum between the PLC group and the benign tumors group(P＜0.05).The level of serum TXNIP in the treatment effective group[(99.52±14.12)pg/mL]was obviously higher than that in the treat-ment ineffective group[(85.19±15.17)μg/mL],and the difference was statistically significant(t=3.621,P＜0.05),while the BIRC5 expression level[(15.26±3.65)pg/mL]was obviously lower than that in the treatment ineffective group[(19.13±3.74)pg/mL],and the difference was statistically significant(t=3.833,P＜0.05).The serum TXNIP expression level in early PLC patients[(101.39±12.85)pg/mL]was obviously higher than that in late stage patients[(91.27±13.36)μg/mL],and the difference was statistically significant(t=3.154,P＜0.05),while the BIRC5 expression level[(14.43±3.07)pg/mL]was obviously lower than that in late stage patients[(17.74±3.04)pg/mL],and the difference was statistically significant(t=4.439,P＜0.05).The area under the curve(AUC)of serum TXNIP and BIRC5 in diagnosing PLC stag-ing was 0.829(95％CI:0.718-0.909)and 0.795(95％CI:0.679-0.883),respectively,with sensitivity of 81.58％and 89.47％,and the AUC of TXNIP combined BIRC5 in diagnosing PLC staging was 0.899(95％CI:0.802-0.959),with sensitivity of 94.74％.The AUC of serum TXNIP and BIRC5 in predicting the effi-cacy of PLC patients was 0.818(95％CI:0.705-0.901)and 0.761(95％CI:0.642-0.856),respectively,the AUC of the combination of the two was 0.921(95％CI:0.830-0.973),which had higher predictive efficiency(P＜0.05).Conclusion TXNIP is lowly expressed in the serum of patients with PLC,while BIRC5 is highly expressed in the serum of patients with PLC.The combination detection of TXNIP and BIRC5 has certain effi-cacy in the diagnosis of PLC staging and predicting the efficacy of PLC patients.

Objective:To explore the effect of motivational enhancement group intervention conducted by nur-ses on the motivation of self-improvement,relapse tendency and self-esteem in the recovering male amphetamine addicts.Methods:Ninety-eight recovering male amphetamine addicts in the Compulsory Detoxification Center were randomly divided into control group(n=54)and motivational enhancement group(n=44).The addicts in the con-trol group received routine education while those in the motivational enhancement group received routine education combined with a 12-week motivational enhancement group intervention conducted by nurses.The Stages of Change Readiness and Treatment Eagerness Scale(SOCRATES),Relapse Tendency Questionnaire,and Rosenberg Self-es-teem Scale(RSES-T)were applied to measure the effect,before and after the intervention.Results:In both two groups,the scores of RSEST,questionnaire of relapse tendency,and self-confidence of detoxification were lower af-ter 12-week intervention than at the baseline(Ps＜0.05).After 12-week intervention,all the above scores were lower in the motivational enhancement group than in the control group(Ps＜0.05).Conclusion:Compared with routine education,the motivational enhancement group intervention conducted by nurses may be more effective to improve their self-confidence in drug rehabilitation and prevention of relapse in recovering male amphetamine ad-dicts,however,the improvement on self-esteem is limited.

Objective To explore the effects of military operation types on the mental health of Chinese veterans and the mediating role of psychological quality based on a dual-factor model of mental health.Methods Cross-sectional study design was adopted in this study.Self-designed demographic information questionnaire,patient health questionnaire depression module-9 item(PHQ-9),general anxiety disorder-7(GAD-7),satisfaction with life scale and psychological quality questionnaire were used to survey on 3 027 Chinese veterans.Results ① Compared to the one-factor model and the two-factor models with other indicators,the dual-factor model of mental health,with anxiety symptoms as a negative indicator and life satisfaction as a positive indicator,fitted better(Chi-square/df=8.927,GFI=0.974,AGFI=0.962,RMSEA=0.051,NNFI=0.985,IFI=0.988,CFI=0.988).②Taking the subjects who did not participate in war/non-war military operations as the reference,psychological quality showed significant relatively mediating effects between war and life satisfaction,and between war and anxiety symptoms(P＜0.05),while no such significances were observed in the corresponding ones for non-war military operations.③ War could decrease veterans'life satisfaction through full mediation of cognitive,adaptive and personality dimensions of psychological quality,and increase anxiety symptoms through partial mediation of the personality dimension of psychological quality.Conclusion The dual-factor model of mental health is applicable to Chinese veteran population,and psychological quality plays a mediating role between war and mental health.
