Objective To explore the influencing factors of cognitive impairment in non-dialysis patients with chronic kidney disease(CKD).Methods A total of 60 hospitalized non-dialysis patients with CKD in the Department of Nephrology of Northern Jiangsu People's Hospital Affiliated to Yangzhou University from September 2022 to September 2023 were enrolled as research objects.According to the estimated glomerular filtration rate(eGFR),they were divided into stage 1 to 2 of CKD group[eGFR ≥60 mL/(min·1.73 m2)]with 23 cases,the stage 3 of CKD group[eGFR 30～＜60 mL/(min·1.73 m2)]with 20 cases,and stage 4 to 5 of CKD group[eGFR＜30 mL/(min·1.73 m2)]with 17 cases.The Montreal Cognitive Assessment Scale(MoCA)was used to evaluate the cognitive function of the patients.Basic data and common clinical laboratory in-dicators on hospital admission were collected to analyze the differences in cognitive function levels under different renal function statuses and to explore the influencing factors of cognitive impairment.Results The incidence rates of cognitive impairment in the stage 1 to 2 of CKD group,stage 3 of CKD group,and stage 4 to 5 of CKD group were 47.8％,85.0％,and 94.1％respectively,the median MoCA scored 26,24 and 20 respectively,with statistically significant between-group differ-ences(P＜0.05).Cognitive function was significantly negatively correlated with age(r=-0.634,P＜0.001),blood urea nitrogen(BUN)(r=-0.574,P＜0.001),serum creatinine(Cr)(r=-0.417,P＜0.001),cystatin C(Cys-C)(r=-0.327,P=0.011),serum β2-microglobulin(β2-MG)(r=-0.259,P=0.046),and N-terminal pro-brain natriuretic peptide(NT-proBNP)(r=-0.474,P＜0.001),and was significantly positively correlated with hemoglobin(HB)(r=0.401,P=0.001)and eGFR(r=0.485,P＜0.001).Multivariate Logistic regression analysis showed that age(P=0.006)and NT-proBNP(P=0.041)were influencing factors of cognitive im-pairment in non-dialysis patients with CKD.Receiver operating characteristic(ROC)curve analysis showed that the area under the curve(AUC),sensitivity,and specificity of age for prediction were 0.860,0.864 and 0.812 respectively,the AUC,sensitivity,and specificity of NT-proBNP for pre-diction were 0.808,0.795 and 0.875 respectively,and the combined prediction of age and NT-proBNP had an AUC,sensitivity,and specificity of 0.893,0.955,and 0.750,respectively.Conclusion As renal function deteriorates,the incidence rate and severity of cognitive impairment in non-dialysis patients with CKD tend to increase.Advanced age,renal function deterioration,high NT-proBNP level,and anemia are associated with the occurrence of cognitive impairment in non-di-alysis patients with CKD,among which age and NT-proBNP are influencing factors for cognitive im-pairment.

Objective This study is focused on ultrasound multimodality examination,which refers to the combined use of three ultrasound examination modalities,ultrasound(US),acoustic radiation force impulse(ARFI)imaging,and contrast-enhanced ultrasound(CEUS).The purpose of this study is to analyze the value of applying ultrasound multimodality examination in the differential diagnosis of benign and malignant breast non-mass-like lesions(NMLs).Methods Cases of breast NMLs were analyzed retrospectively,and the nature of all the lesions was verified by pathological examination.Based on the gray-scale ultrasound image characteristics,the cases were classified into types Ⅰto Ⅴ,and type Ⅰ and type Ⅱ were further classified into 4 subtypes,Ⅰa,Ⅰ b,Ⅱ a,and Ⅱ b,according to whether there was also calcification,and the proportion of malignant cases in each subtype was statistically analyzed.Logistic regression models of US,US+ARFI,US+CEUS,and US+ARFI+CEUS for the diagnosis of malignant cases were established,ROC curves were drawn,the area under the curve(AUC)was calculated,and comparisons were made accordingly.The detection rate of malignant NMLs without calcification(atypical malignant NMLs)by the combination examination of US,ARFI,and CEUS was analyzed.Results A total of 407 cases were included in the study.All subjects were female,aged 22 to 81 years,with the average age being(47.0±1 1.0)years.There were 220 benign cases and 187 malignant cases.Ranked from the highest to the lowest,the malignancy proportion of the different types wasⅠb＞Ⅱb＞Ⅲ＞V＞Ⅰa＞Ⅱa＞Ⅳ.The malignant proportion of the low echo area with calcification was significantly higher than that of the lesions without calcification.The AUC(95％confidence interval[CI])for diagnosing malignant cases with the logistic regression models of US,US+ARFI,US+CEUS,and US+ARFI+CEUS were 0.895(0.862-0.927),0.908(0.878-0.937),0.921(0.893-0.948),and 0.927(0.902-0.952),respectively.Comparison of the AUC of the 4 regression models showed significant differences(P＜0.001).The detection rate of US for NMLs without calcification was 80.7％.When US was used in combination with ARFI and CEUS,86.4％of the malignant NMLs lesions without calcification could be detected if the lesion CEUS score was 4 or 5 points or if shear-wave velocity(SWV)≥4.28 m/s.Conclusion Breast NMLs with calcification show high risks of malignancy,and a pathological examination is always recommended for a conclusive diagnosis.Ultrasound multimodality examination can improve the diagnostic accuracy of breast NML without calcification.

Objective:To explore the relationship between AluYb8 insertion in the MUTYH gene and the risk of decreased left ventricular diastolic function in the elderly.Methods:In the retrospective analysis, 498 elderly patients with decreased left ventricular diastolic function(the disease group)and 155 people without left ventricular diastolic function(the control group)were recruited.Polymerase chain reaction was employed to analyze the genotype distribution of AluYb8 insertion in MUTYH gene.Cardiac function was measured by high-resolution color Doppler ultrasound.Results:The frequencies of the A/A, A/P and P/P genotypes were 30.1%(150/498), 48.4%(241/498)and 21.5%(107/498)in patients with decreased left ventricular diastolic function, and 27.7%(43/155), 54.8%(85/155)and 17.5%(27/155)in the control group, respectively.There were no significant differences in genotype( χ2=2.162, P=0.339)and allele frequency( χ2=1.342, P=0.794)between the two groups.Further analysis after stratification revealed that there were statistically significant differences in genotype( χ2=7.173, P=0.028)and allele frequency( χ2=8.352, P=0.015). Multivariate Logistic regression analysis showed that, in elderly patients with diabetes, P-allele carriers had a higher risk of decreased left ventricular diastolic function than non-carriers( OR=3.450, 95% CI: 1.148-10.372, P=0.027). Conclusions:AluYb8 insertion in the MUTYH gene may be associated with the risk of decreased left ventricular diastolic function in the elderly with diabetes.

Objective:To explore the association between non-thyroid illness syndrome(NTIS)and pre-sarcopenia in the elderly.Methods:In the retrospective study, a total of 219 patients aged 60-85 years in Department of Geriatrics, Sir Run Run Hospital, Nanjing Medical University from April 2018 to March 2021, included 60 patients with NTIS and 159 patients without NTIS.Clinical data, laboratory results and body composition data were collected.Pre-sarcopenia was diagnosed based on human composition determination data and diagnostic criteria of pre-sarcopenia.Logistic regression analysis, Pearson's correlation analysis and the area under receiver operator characteristic curve(ROC)were used to explore the correlation between serum thyroid hormone levels and diagnostic data level of pre-sarcopenia.Results:Of 54 pre-sarcopenia patients, 30.3%(36/119)were male, 18.0%(18/100)were female with statistically significantly differences( P<0.01). Mean age was higher in both male and female patients in the NTIS group than in the non-NTIS group( P<0.01). The body mass index, levels of triiodothyronine(T3), free triiodothyronine(FT3), hemoglobin, and albumin were lower in NTIS group than in non-NTIS group( P<0.05). The prevalence of presarcopenia in female patients was higher in the NTIS group than in the non-NTIS group[42.9%(10/17) vs.10.6%(8/83), χ2=9.564, P<0.01]. Multivariate logistic regression analysis showed that the risk of pre-morbidity of sarcopenia was significantly higher in NTIS patients than in non-NTIS patients.FT3 was positively correlated with skeletal muscle mass index, fat-free body weight, and phase angle, and negatively correlated with visceral fat area( r=-0.17, P<0.05). While, free thyroxine(FT4)was negatively correlated with skeletal muscle mass index( r=-0.21), fat-free body weight( r=-0.16)and phase Angle( r=-0.2, P<0.01 or P<0.05), and was positively correlated with body fat percentage and visceral fat area( r=0.20 and 0.22, respectively, P<0.01). The use of area under ROC curve(AUC)of FT3 predicting sarcopenia stage showed that the AUC was 0.768(95% CI: 0.691~0.844). Conclusions:In elderly patients, NTIS is correlated with the pre-sarcopenia in the elderly, and FT3 and FT4 are related to muscle mass.The low level of FT3 can predict the pre-validation of pre-sarcopenia.

Objective:To investigate the status quo of continuing education and training needs among general practitioners in Pudong New Area of Shanghai.Methods:An online questionnaire survey was conducted among general practitioners registered in the community health service center of Shanghai Pudong New Area in September 2019. The questionnaire included items of general information, the status quo of continuing education, the training needs and demands, and the knowledge and skills to be improved.Results:There were total 1 824 general practitioner in Pudong New Areal, 861 participated in the survey with a participant rate of 47.2%. A total of 861 valid questionnaires retrieved with a response rate of 100.0%. Among all participants, 79 (9.18%) thought that continuing education was very useful for improving or developing their professional ability, 564 (65.51%) thought it was useful, and 41 people (4.76%) thought it was almost useless. There were significant different in views on the roles of continuing education among participants with different ages, types of registration, and working years (χ2=15.544, 15.382, 21.979; P<0.05). There are 112 participants (13.01%) who spend less than 1 day in continuing education each month, and 224 (26.02%) who spent more than 3 days a month in continuing education, the times of attending continuing education was related to the taking administrative duty for general practitioners (χ2=9.551, P<0.05). When general practitioners choose continuing education programs, the first consideration was the practicability of the contents [772 (31.94%)], followed by the form of teaching [541 (22.38%)]. The three most recognized forms of continuing education courses were online learning (28.22%), training and off-line teaching (25.58%) and special lectures (24.69%) The three most required knowledge and skills to be improved through continuing education were the endocrine system, respiratory system, and blood circulation system. Conclusions:The survey shows the current status and traing needs of continuing education among general practitioners in Shanghai Pudong New Area, which indicates that it is necessary to take the job competence as the core and carry out various activities of continuing education for general practitioners in community health service centers.

Objective: To understand the consistency of ALK Ventana-D5F3 immunohistochemistry (IHC) interpretation in Chinese lung adenocarcinoma among histopathologists from different hospitals, and to recommend solution for the problems found during the interpretation of ALK IHC in real world, with the aim of the precise selection of patients who can benefit from ALK targeted therapy. Methods: This was a multicenter and retrospective study. A total of 109 lung adenocarcinoma cases with ALK Ventana-D5F3 IHC staining were collected from 31 lung cancer centers in RATICAL research group from January to June in 2018. All cases were scanned into digital imaging with Ventana iSCANcoreo Digital Slide Scanning System and scored by 31 histopathologists from different centers according to ALK binary (positive or negative) interpretation based on its manufacturer′s protocol. The cases with high inconsistency rate were further analyzed using FISH/RT-PCR/NGS. Results: There were 49 ALK positive cases and 60 ALK negative cases, confirmed by re-evaluation by the specialist panel. Two cases (No. 2302 and No.2701) scored as positive by local hospitals were rescored as negative, and were confirmed to be negative by RT-PCR/FISH/NGS. The false interpretation rate of these two cases was 58.1% (18/31) and 48.4% (15/31), respectively. Six out of 31 (19.4%) pathologists got 100% accuracy. The minimum consistency between every two pathologists was 75.8%.At least one pathologist gave negative judgement (false negative) or positive judgement (false positive) in the 49 positive or 60 negative cases, accounted for 26.5% (13/49), 41.7% (25/60), respectively, with at least one uncertainty interpretation accounted for 31.2% (34/109). Conclusion There are certain heterogeneities and misclassifications in the real world interpretation of ALK-D5F3 IHC test, which need to be guided by the oncoming expert consensus based on the real world data.

Objective: To investigate whether topical mucopolysaccharide polysulfate (MPS) cream can reduce the incidence of eczema and skin atrophy in patients with moderate- or low-risk infantile hemangioma after the treatment with topical beta-blockers or 595-nm pulsed dye laser (PDL) , and to analyze factors influencing the occurrence of eczema and skin atrophy. Methods: A total of 722 patients aged 0- 1 years with moderate- or low-risk infantile hemangioma were enrolled from 5 Children′s Hospitals in China. According to the disease condition and therapy acceptability, these patients were divided into 6 groups to be treated with topical beta-blockers and MPS cream (blocker+ MPS group) , topical beta-blockers (blocker group) , 595-nm PDL and topical MPS cream (PDL+ MPS group) , 595-nm PDL (PDL group) , 595-nm PDL combined with topical beta-blockers and MPS cream (PDL+ blocker+ MPS group) , and 595-nm PDL and topical beta-blockers (PDL+ blocker group) , respectively. All the externally applied agents were applied twice a day, and PDL was performed once every 4 weeks. Efficacy and adverse reactions were evaluated after 3-month treatment. Univariate and multivariate Logistic regression analyses were carried out to analyze factors influencing the incidence of eczema and skin atrophy in patients with infantile hemangioma after treatment, and chi-square test was carried out to compare efficacy among the groups. Results: After 3-month treatment, multivariate Logistic regression analysis for comparing the blocker+ MPS group with blocker group showed that the risk factor for eczema on the surface of hemangiomas was no topical treatment with MPS cream (P= 0.007, OR= 3.887, 95% CI: 1.439-10.493) , while no correlations were observed between the occurrence of skin atrophy on the surface of hemangiomas and analyzed factors. Multivariate Logistic regression analysis for comparing the PDL+MPS group with PDL group showed that no topical treatment with MPS cream (P < 0.001, OR= 7.402, 95% CI: 2.604-21.042) and northern areas (P < 0.001, OR= 67.048, 95% CI: 7.977-563.518) were risk factors for eczema on the surface of hemangiomas, and risk factors for skin atrophy on the surface of hemangiomas included no topical treatment with MPS cream (P = 0.001, OR = 9.371, 95 CI: 2.590 - 33.900) and abundant blood supply of hemangiomas (P = 0.036, OR = 2.971, 95% CI: 1.075-8.208) . Multivariate Logistic regression analysis for comparing the PDL + blocker+ MPS group with PDL+ blocker group showed that risk factors for eczema on the surface of hemangiomas were no topical treatment with MPS cream (P= 0.005, OR= 3.426, 95% CI: 1.446-8.119) and northern areas (P < 0.001, OR= 31.704, 95% CI: 6.924-145.158) , and risk factors for skin atrophy on the surface of hemangiomas included no topical treatment with MPS cream (P < 0.001, OR= 6.011, 95% CI: 2.558-14.126) and southern areas (P= 0.022, OR= 3.021, 95% CI: 1.177-7.753) . After 3-month treatment, the response rate was significantly higher in the PDL group than in the PDL+ MPS group (χ²= 4.531, P= 0.033) , and significantly higher in the blocker group than in the blocker+ MPS group (χ²= 4.344, P= 0.037) . There were no significant differences in the response rate or cure rate among the other groups (all P > 0.05) . Conclusion During the treatment of moderate- or low-risk infantile hemangioma with topical beta-blockers or 595-nm PDL, the combination with topical MPS cream can reduce the occurrence of eczema and skin atrophy without affecting the therapeutic effect.

Objective To compare the effects of different oral motor interventions,including non-nutritive sucking (NNS) and acupuncture point stimulation of oral and cheek combined with NNS,on oral feeding of prematures.Methods A total of 164 prematures were randomly divided into three groups. Group A (n=53) received routine feeding nursing care;Group B (n=54) were given non-nutritive sucking for 3 minutes before and after feeding,with 8 times per day;Group C (n=57) were given acupuncture point stimulation of oral and cheek for 17 minutes and non-nutritive sucking for 3 minutes before feeding,with twice per day.Results There was no significant difference between group B and C on the transitional time from the initiation of oral feeding to full oral feeding (P>0.05). Transitional time of both groups were significant shorter than that of group A (P<0.05). Feeding performance of prematures from the initiation of oral feeding to full oral feeding in group C was significant better than group A and B (P<0.05). There was significant difference in the feeding performance of prematures at the initiation of oral feeding between A and B group (P<0.05),but no significant differences between two groups after full oral feeding (P>0.05).Conclusions Different oral motor interventions including NNS and acupuncture point stimulation of oral and cheek combined with NNS can reduce the time of achieving full oral feeding in prematures. Acupuncture point stimulation of oral and cheek combined with NNS performs better than only NNS on feeding in prematures.

This article was aimed to study the antioxidant and antihyperlipidemic effect of total phenolic composition prepared from pineapple (A nanas comosus L.) leave. It had a rapid absorption after intragastric administration and the principle ingredient, p-coumaric acid, reached the peak concentration after 5 minutes of administration. The mice model with single intragastric administration of lipid and glucose were used in the observation of changes on postprandial glucose, lipid and intestinal lipase at different time points after drug administration. The results showed that phenols of pineapple leave can inhibit triglyceride and glucose absorption in certain extent. No significant effect was observed on inhibition at 30 minutes after the phenol administration. However, the intestinal lipase activity was obviously inhibited in normal mice and the intestinal lipase activity decline caused by acute lipid consumption can be reversed. It was concluded that the phenols pineapple leave may inhibit the absorption of lipids with correlation to lipase activity. It had certain regulation effect on the high postprandial glucose and fat absorption.
