Objective To explore the application value of combining the ultrasound breast imaging reporting and data system(BI-RADS)classification with serum fibroblast growth factor receptor 1(FGFR1)and growth differentiation factor 3(GDF3)in the differential diagnosis of benign and malignant breast masses.Methods A total of 159 patients with breast masses were selected and divided into the benign mass group(n=83)and the malignant mass group(n=76)based on postoperative pathological diagnosis.All patients underwent ultrasound examination,and enzyme-linked immunosorbent assay(ELISA)was applied to detect serum levels of FGFR1 and GDF3.Receiver operating characteristic(ROC)curve was applied to analyze the diagnostic value of ultrasound BI-RADS classification and serum FGFR1 and GDF3 levels for benign and malignant breast masses.Kappa test was applied to analyze the consistency between various diagnostic methods and pathological diagnosis.Results The serum levels of FGFR1 and GDF3,the proportions of irregular morphology,unclear boundaries,spiculation,microcalcifications,blood flow grade Ⅱ-Ⅲ and posterior echo attenuation,RI and PI were higher in the malignant tumor group than those in the benign tumor group(P＜0.05).The area under the curve(AUC)of FGFR1,GDF3 and ultrasound BI-RADS classification in the differential diagnosis of benign and malignant breast masses separately and in combination was 0.802(95%CI:0.732-0.871),0.817(95%CI:0.751-0.884),0.848(95%CI:0.784-0.912)and 0.956(95%CI:0.918-0.993),respectively.The combined diagnosis was more effective than that of the individual diagnosis of each indicator.The consistency between the individual and combined diagnosis of benign and malignant breast masses and pathological diagnosis showed that the Kappa values were 0.517,0.514,0.688 and 0.912,respectively,with the highest consistency observed in the combined diagnosis(P＜0.05).Conclusion Ultrasound BI-RADS classification combined with serum FGFR1 and GDF3 has high application value in the differential diagnosis of benign and malignant breast masses.

Objective To explore the impact of seasonal and temperature variations on fasting blood glucose(FPG)in patients with type 2 diabetes(T2DM).Methods A retrospective analysis was conducted on clinical data of 31 994 T2DM patients managed by community health service center in Minhang District,Shanghai,from January 1,2020 to October 31,2023.The effect of seasonal and temperature variations on FPG levels and blood glucose control was investigated in T2DM patients.Results A total of 72 334 FPG tests were conducted in 31 994 T2DM patients,with an average of 2.26 tests per person.The number of tests conducted in spring,summer,autumn and winter were 15 558,34 018,21 929 and 829,respectively.The FPG levels of T2DM patients were lower in summer and autumn compared to those of winter and spring(P<0.05),while the FPG control rates were higher in summer and autumn compared to those of winter and spring(Bonferroni-corrected,P<0.008).There were no significant differences in FPG levels and blood glucose control rates between spring and winter,or between summer and autumn.The results of the multilevel mixed-effect Logistic model analysis with FPG control status as the dependent variable revealed that the risk of uncontrolled FPG in T2DM patients during winter and spring was 47%(aOR=1.465,95%CI:1.156-1.855)and 51%(aOR=1.510,95%CI:1.384-1.645),respectively,which was higher than that of autumn.The levels of FPG and the incidence of FPG abnormalities reached peak in February and reached the trough in September.Both the FPG levels and the incidence of FPG abnormal exhibited a trend of increasing with the decrease of temperature,and with a lag effect observed.Spearman rank correlation test indicated that there was a negative correlation between FPG levels and incidence of abnormal FPG and the monthly average daily temperature one month lagged(rs=-0.951,P＜0.001 and rs=-0.944,P＜0.001).Conclusion FPG levels of T2DM patients exhibit a pronounced seasonal pattern of elevation during winter and spring,accompanied by a reduction in blood glucose control rates.FPG levels and the prevalence of abnormal FPG exhibit a negative correlation with the monthly average daily temperature,and there is a lag effect.

Objective To investigate the effect of benserazide combined with respiratory training on post-stroke dysphagia.Methods A total of 120 patients with dysphagia after stroke were prospectively selected and randomly divided into the combination group and the breathing exercise group,with 60 cases in each group.The breathing exercise group was treated with rehabilitation breathing training,and the combination group was treated with dopa serazide on the basis of rehabilitation breathing training,3 times a day,1 tablet once.The traditional Chinese medicine(TCM)syndrome scores,clinical efficacy and swallowing function indexes including dysphagia angiography score(VDS),osmotic-aspiration scale(PAS)score,Lowada drinking water test score and VFSS score were compared between the two groups.Nutritional indices[total cholesterol(TC),triglyceride(TG),albumin(ALB),hemoglobin(Hb)],related indexes of nerve function[nerve function and serum growth differentiation factor 15(GDF-15),central nerve specific protein soluble protein-100β(S100β)],quality of life and anxiety disorder score[Quality of Life Rating Scale(SF-36)score,Generalized Anxiety Disorder Scale(GAD-7)score]and adverse reactions were compared between the two groups.Results The total effective rate of the combination group(91.67%)was obviously increased(P＜0.05)compared to the breathing exercise group(58.33%).Compared with before treatment,after treatment,tongue flaccidity,slow swallowing,choke after drinking water,tongue coating ecchymosis,score of fine pulse,VDS,PAS,score of Lowada drinking water test,GDF-15 level and GAD-7 score were decreased in the two groups,and those of the combination group were significantly lower than the breathing exercise group(P＜0.05).The levels of TC,TG,ALB,Hb,S100β,VFSS and SF-36 were increased in the two groups,and those of the combination group were higher than the breathing exercise group(P＜0.05).There was no significant difference in the incidence of adverse reactions between the two groups.Conclusion Benserazide combined with respiratory training has high clinical efficacy in patients with post-stroke dysphagia,which can effectively improve the TCM evidence score and nutritional indicators,improve swallowing function,reduce anxiety,improve quality of life,and have more ideal clinical application.

Objective To explore the predictive value of serum levels of capsaicin receptor 1(TRPV1),matrix metalloproteinase inhibitor 4(TIMP4)and transforming growth factor beta 1(TGF-β1)for disease recurrence in patients with benign paroxysmal positional vertigo(BPPV).Methods A total of 326 BPPV patients were selected and used as the BPPV group,and 357 healthy individuals who underwent physical examinations during the same period were selected and used as the control group.According to the recurrence status of BPPV patients after 1 year of reduction treatment,patients were divided into the non recurrence group(264 cases)and the recurrence group(62 cases).Enzyme linked immunosorbent assay was used to detect serum levels of TRPV1,TIMP4 and TGF-β1 in patients.Multivariate Logistic regression analysis was performed to analyze influencing factors of recurrence in BPPV patients.Receiver operating characteristic(ROC)curve was used to evaluate the predictive value of TRPV1,TIMP4,and TGF-1 levels for recurrence in BPPV patients.Results TRPV1 and TIMP4 were lower in the BPPV group than those in the control group,while TGF-β1 was higher than that in the control group(P＜0.05).The TGF-β1 score in the recurrence group were higher than those in the non recurrence group,while TRPV1 and TIMP4 were lower than those in the non recurrence group(P＜0.05).Serum TRPV1 and TIMP4 levels were lower in the recurrence group than those of the non recurrence group,and TGF-1 levels were higher in the recurrence group than those of the non recurrence group(P＜0.05).The decreased serum levels of TRPV1 and TIMP4 were risk factors for recurrence in BPPV patients(P＜0.05).The area under the curve(AUC)of TRPV1,TIMP4,TGF-β1 and their combined prediction of recurrence in BPPV patients were 0.795(95%CI:0.748-0.838),0.803(95%CI:0.756-0.845),0.810(95%CI:0.764-0.851)and 0.945(95%CI:0.914-0.967),respectively.The combined detection value of TRPV1,TIMP4 and TGF-β1 levels were better than that of single detection in predicting the recurrence in BPPV patients(all P＜0.05).Conclusion The serum levels of TRPV1,TIMP4 and TGF-β1 are independent factors affecting the recurrence of BPPV patients,and the combination of the three has a higher predictive value for the recurrence of BPPV patients.

Objective To investigate the expression and clinical significance of Claudin-6(CLDN6),tripartite motif-containing protein 59(TRIM59)and chemokine-like factor-like MARVEL transmembrane domain containing member 6(CMTM6)in nasopharyngeal carcinoma(NPC)tissue.Methods A total of 135 NPC patients were selected as the study objects,and cancer tissue(observation group)and para-cancer tissue(control group)of all patients were collected.All patients were followed up for 3 years.According to the follow-up results,93 surviving patients were included in the survival group and 42 dead patients were included in the death group.The mRNA expressions of CLDN6,TRIM59 and CMTM6 were determined by fluorescence quantitative PCR.Multivariate Cox regression was used to analyze the influencing factors of death in NPC patients.Kaplan-Meier method was used to analyze the relationship between the expression levels of CLDN6,TRIM59,CMTM6 and the prognosis of NPC patients.Results Compared with the control group,mRNA expressions of CLDN6,TRIM59 and CMTM6 were increased in the observation group(P＜0.05).There were no significant differences in age,sex,body mass index,TNM stage,bone metastasis,smoking history,drinking history and hypertension history between the survival group and the death group.Compared with the survival group,the proportion of NPC family history and the mRNA expression of CLDN6,TRIM59 and CMTM6 in cancer tissue were increased in the death group(P<0.05).Multivariate Cox regression analysis showed that the increased levels of CLDN6,TRIM59 and CMTM6 in cancer tissue were influential factors for death of NPC patients(P＜0.05).According to the mean expression levels of CLDN6,TRIM59 and CMTM6 mRNA in cancer tissue,patients were divided into the low expression group and the high expression group.The 3-year survival rate of the high expression group was significantly lower than that of the low expression group(P＜0.05).Conclusion The mRNA expressions of CLDN6,TRIM59 and CMTM6 in NPC tissue are significantly increased,which is a risk factor for death in NPC patients,and the mRNA expressions of CLDN6,TRIM59 and CMTM6 are correlated with the prognosis of patients.

Objective To analyze influencing factors of small airway dysfunction(SAD)in children with bronchial asthma,and construct a risk prediction model for SAD.Methods A total of 221 bronchial asthma children with normal pulmonary ventilation function were retrospectively selected as the modeling group.According to the presence of SAD,children were divided into the SAD group(43 cases)and the non-SAD group(178 cases).The related factors affecting the occurrence of SAD were analyzed by univariate analysis and multivariate Logistic regression analysis,and risk prediction model of SAD was constructed.In addition,74 bronchial asthma children with normal pulmonary ventilation function were collected and used as the validation group.Hosmer-Lemeshow test was adopted to evaluate the calibration of the model.Receiver operating characteristic(ROC)curve was drawn and area under the curve(AUC)was calculated to evaluate the predictive efficiency of the prediction model.Results Multivariate Logistic regression analysis showed that poor asthma control(OR=10.722,95%CI:4.044-28.428),allergic rhinitis in the attack stage(OR=4.816,95%CI:1.929-12.023)and long use of inhaled corticosteroids(ICS)or ICS/long-acting β2 receptor agonist(LABA,OR=2.903,95%CI:1.269-6.643)were independent risk factors for SAD in children(P＜0.05),and older age at first onset of suspected asthma symptoms(OR=0.599,95%CI:0.395-0.907)was a protective factor.Hosmer-Lemeshow test showed good calibration(χ2=8.301,P=0.307).The AUC,sensitivity and specificity of the model in the modeling group for predicting the occurrence of SAD in children with bronchial asthma were 0.820(95%CI:0.749-0.892),74.42%and 78.65%,and the AUC,sensitivity,specificity and accuracy of the model in the validation group were 0.849(95%CI:0.718-0.981),75.00%,94.83%and 90.54%(67/74).Conclusion Children with bronchial asthma who are younger at the time of their first suspected asthma symptoms,poor asthma control,allergic rhinitis in the exacerbation phase,and longer duration of use of ICS or ICS+LABA/LTRA are at higher risk of SAD.Therefore,SAD risk prediction model constructed on this basis has good predictive ability.

Objective To investigate the impact and predictive value of high mobility group protein B1(HMGB1)and angiopoietin like protein 2(Angptl-2)on coronary artery damage in children with Kawasaki disease.Methods A total of 114 children with Kawasaki disease were selected and divided into the normal coronary artery group(85 cases)and the coronary artery lesion group(29 cases)according to the presence or absence of coronary artery lesions.The general clinical data of the two groups were compared.Enzyme linked immunosorbent assay was applied to detect serum levels of HMGB1 and Angptl-2 in children and compared between the two groups.Logistic regression was applied to analyze the influencing factors of coronary artery damage in children with Kawasaki disease.Receiver operating curve(ROC)was applied to analyze the predictive value of serum levels of HMGB1 and Angptl-2 for coronary artery damage in children with Kawasaki disease.Results The serum levels of HMGB1 and Angptl-2 were significantly higher in acute stage than those in remission stage(P＜0.05).Before treatment,the duration of fever,white blood cell count,erythrocyte sedimentation rate,procalcitonin and serum HMGB1 and Angptl-2 levels were significantly higher in the coronary artery lesion group than those in the normal coronary artery group(P＜0.05).Logistic regression analysis showed that the duration of fever,white blood cell count,erythrocyte sedimentation rate,procalcitonin,HMGB1 and Angptl-2 levels before treatment were all independent risk factors for coronary artery damage in children with Kawasaki disease(P＜0.05).The area under the curve(AUC)of serum HMGB1 and Angptl-2 for diagnosing coronary artery damage in children with Kawasaki disease was 0.907(95%CI:0.838-0.953)and 0.857(95%CI:0.780-0.916),respectively,with cut-off value of 59.62 μg/L and 10.35 μg/L,respectively.The AUC,sensitivity and specificity of the combined diagnosis of coronary artery damage in children with Kawasaki disease were 0.958(95%CI:0.903-0.987),93.10%and 90.59%,respectively,which were better than their individual diagnose.Conclusion The serum levels of HMGB1 and Angptl-2 are obviously elevated in children with Kawasaki disease complicated by coronary artery damage,and the combined detection of HMGB1 and Angptl-2 levels in serum can provide a good prediction for coronary artery damage in children with Kawasaki disease.

Objective To analyze the correlation between the levels of high mobility group protein B1(HMGB1),monocyte chemotactic protein-1(MCP-1)and the prognosis of patients with sepsis combined with acute kidney injury(AKI).Methods A total of 100 patients with sepsis combined with AKI treated with continuous renal replacement therapy(CRRT)were included in this study and clinical data before treatment were collected.The levels of HMGB1 and MCP-1 were detected by enzyme-linked immunosorbent assay before and after CRRT treatment.Follow-up began on the day after the end of CRRT treatment,and the end point of follow-up was death or survival within 30 days.Patients were divided into the death group(31 cases)and the survival group(69 cases)according to survival status.Cox regression was used to analyze the relationship between HMGB1 and MCP-1 and death within 30 days after CRRT in patients with septic AKI.Receiver operating characteristics(ROC)curve was used to analyze the prognostic value of HMGB1 and MCP-1 in patients with sepsis combined with AKI after CRRT.Resluts The sequential organ failure(SOFA)scores,acute physiology and chronic healthⅡ(APACHE Ⅱ)scores were lower in the survival group than those in the death group(P＜0.05).After CRRT treatment,HMGB1 and MCP-1 levels were lower in the survival group than those in the death group(P＜0.05).Cox regression analysis showed that SOFA score,APACHE Ⅱscore,HMGB1 and MCP-1 increase after treatment were risk factors for death in patients with sepsis complicated with AKI.ROC curve analysis showed that the AUC of SOFA score,APACHE Ⅱ score,combined diagnosis of HMGB1 and MCP-1 after treatment was 0.973,which was significantly higher than that of single detection(P＜0.05).Conclusion The increased levels of HMGB1 and MCP-1 in peripheral blood after treatment are independent risk factors for 30-day death in patients with sepsis complicated with AKI after CRRT treatment,and the combined prognostic value is high.

Objective To investigate the prognostic value of vertebral CT parameters for early fusion sink after transforaminal lumbar interbody fusion(TLIF).Methods The clinical and imaging data of 178 patients with lumbar degenerative diseases treated by TLIF were retrospectively studied.The patients were divided into the sedimentation group(n=57)and the non-sedimentation(n=57)group according to the patient's fusion device settlement 3 months after surgery.The results of general data and CT image parameters were compared between the two groups.Multivariate Logistic regression was used to analyze risk factors of early fusion subsidence,and the prediction efficiency was analyzed.Results The incidence of the early fusion sink was 32.0%.Compared with the non-sedimentation group,the sedimentation group had a higher proportion of patients aged≥60 years,osteoporosis,L5-S1 and intervertebral space height,larger fusion contact area and segmental lordosis angle and lower lumbar CT value(P＜0.05).Logistic regression analysis showed that age≥60 years old,surgical level L5-S1,high intervertebral height and large segmental lordosis angle were independent risk factors for the early fusion after TLIF,while high lumbar CT value was protective factor(P＜0.05).Subject working characteristic curves showed that the area under the curve(AUC)of lumbar CT value,intervertebral height,segmental lordosis angle combined with AUC were higher than those of patients aged≥60 years,surgical segment L5-S1,lumbar CT value,intervertebral height,segmental lordosis angle applied alone(P＜0.05).Conclusion Vertebral CT parameters of lumbar CT value,intervertebral height and segmental lordosis angle have higher predictive value for the early fusion after TLIF,and the combined prediction value of the three parameters is higher.

Objective To investigate the clinical distribution and risk factors of metabolic syndrome(MS)in children from Lubei district of Tangshan City from 2020 to 2024.Methods A total of 964 children were identified by multi-segment stratified cluster sampling.A questionnaire survey was conducted on all subjects,and the recovery rate of the questionnaire was 98.0%,with 945 samples recovered.The detection rates of MS in different populations were compared,and risk factors of MS in children were analysed by Logistic regression analysis.Results In 945 children,49(5.19%)had MS,and there was no significant difference in detection rate between different genders of children(P>0.05).There were no significant differences in blood pressure[systolic blood pressure(SBP)and diastolic blood pressure(DBP)],blood lipid[triglycerides(TG)and high density lipoprotein cholesterol(HDL-C)]between children ages 7 to 10 years old and 11 to 14 years old(P>0.05).The values of total cholesterol(TC),low-density lipoprotein cholesterol(LDL-C)and waist circumference(WC)were higher in boys aged 11-14 than those in girls(P＜0.05).The proportion of body weight and obesity,the proportion of physical activity time＜10 h/week,the proportion of family history of hypertension and WC level were higher in the MS group than those in the non-MS group(P＜0.05).Multivariate Logistic regression model showed that weight obesity,physical activity time＜10 h/week,family history of hypertension and high WC value were independent risk factors for MS in children(P＜0.05).Conclusion Obesity,family history of hypertension,time spent in physical activity and higher WC are strongly associated with the development of MS in children,and clinical attention should be paid to them.
