Vascular cognitive impairment(VCI)is a group of syndromes ranging from mild cognitive impairment to dementia caused by cerebrovascular disease,due to the lack of sensitivity and specific biomarkers,it is difficult to identify and diagnose early.Abnormal connectivity is observed in brain regions of patients with vascular cognitive disorders,locates mainly in the default mode network(DMN),and changes in their abnormal functional connectivity correlated with the degree of patients' cognitive impairment.Resting-state functional magnetic resonance imaging(rs-fMRI)is a commonly used method to detect the internal activity of the brain at resting state.The use of various rs-fMRI to study abnormal changes in the DMN in patients with VCI is useful to further investigate the pathogenesis of VCI and provide an objective basis for imaging.This article mainly reviews the application of rs-fMRI in the DMN in patients with VCI,bringing new perspectives for the correct diagnosis and assessment of VCI.

Objective:To study the life characteristics and related risk factors of patients with depression in Shandong Province.Methods:Based on the 2015 mental epidemiological survey database in Shandong Province,a total of 832 patients with depression,807 high-risk individuals with depression,and 819 low-risk individuals were diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition(DSM-Ⅳ)and the Structured Clinical Interview for DSM-Ⅳ-TR Axis I Disorders,Research Version(SCID-I/P).In 2020,SCID-I/P was used for re diagnosis,and the General Health Questionnaire(GHQ-12),Simple Quality of Life question-naire,Pittsburgh sleep quality index(PSQI),Childhood Trauma Questionnaire(CTQ),Social Support Rating Scale(SSRS),Global Pain Scale(GPS),Montreal Cognitive Assessment(MoCA),Simplified Coping Style Question-naire(SCSQ)were used for evaluation.Compare changes in the quality of life of depression patients and construct a risk factor model.Results:Patients with depression had lower scores on the simple quality of life questionnaire at baseline and at retest after 5 years than those in the high-and low-risk groups,those in remission of depression had higher scores on the simple quality of life questionnaire at baseline and at retest after 5 years than those in non-re-mission,and those with new-onset disorder in the high-and low-risk groups had lower scores on the simple quality of life questionnaire at baseline and at retest after 5 years than those with no-onset disorder(Ps＜0.001).Depres-sion diagnosis and PSQI scale scores at baseline negatively predicted at retest after 5 years(β=-0.06,-0.15),while coping style tendencies at baseline positively predicted(β=0.06).The simple quality of life questionnaire at baseline negatively predicted depression diagnosis at retest after 5 years,GHQ-12 scores at retest after 5 years,and PSQI scale scores at retest after 5 years(β=-0.11,-0.17,-0.09),while the simple quality of life question-naire at baseline positively predicted coping style tendencies at retest after 5 years(β=0.13).Depression diagnosis at retest after 5 years,GHQ-12 scores at retest after 5 years,PSQI scale scores at retest after 5 years,coping style tendencies at retest after 5 years,SSRS scale scores,CTQ scale scores,GPS scale scores,and the simple quality of life questionnaire at baseline all influenced the simple quality of life questionnaire at retest after 5 years through ei-ther direct or indirect pathways.Conclusion:It suggest that the quality of life is lower in patients with depression than in the general population.Depression diagnosis,sleep,mental health,pain,social support,childhood trauma and coping are direct and indirect risk factors affecting life.

Objective To investigate the relationship between serum periostin (POSTN) level and bone mineral density in patients undergoing maintenance hemodialysis (MHD). Methods Ninety-five patients who had received MHD treatment for more than 3 months in the Hemodialysis Center of Qingdao Municipal Hospital from October 2022 to October 2023 were enrolled as experimental group. Meanwhile, 50 healthy individuals undergoing health examinations in the Physical Examination Center of the same hospital during the same period were selected as the control group. Clinical data such as gender and age were collected for both groups. Fasting venous blood samples were collected before dialysis to measure parathyroid hormone (PTH), alkaline phosphatase (ALP), urea nitrogen, serum creatinine, serum calcium, serum phosphorus, and other indicators. Serum POSTN levels in MHD patients and healthy individuals were determined using enzyme-linked immunosorbent assay (ELISA). The correlation between serum POSTN levels and bone mineral density in MHD patients was explored. Univariate and multivariate binary Logistic regression analyses were performed to identify risk factors for low bone mineral density in MHD patients and assess the clinical value of serum POSTN level in predicting low bone mineral density in these patients. Results The serum POSTN level in the experimental group were significantly higher than those in the control group (P < 0.05). These patients were divided into two groups based on T-values: normal bone mass group(47 cases, T value >-1.0) and low bone mineral density (48 cases, T value≤-1.0). The low bone mineral density group had significantly higher serum POSTN levels, dialysis vintage, PTH, ALP, serum phosphorus, β₂-microglobulin levels, and a higher proportion of females compared to the normal bone mass group (P < 0.05). Pearson correlation analysis revealed negative correlations of bone mineral density T values with serum POSTN, dialysis vintage, C-reactive protein, PTH, ALP, serum phosphorus, and β₂-microglobulin in MHD patients (r=-0.695, -0.688, -0.246, -0.528, -0.216, -0.309, -0.293; P < 0.05). Multivariate binary Logistic regression analysis showed that after adjusting for confounding factors such as dialysis vintage, PTH, and ALP, high serum POSTN level was an independent risk factor for low bone mineral density in MHD patients. The receiver operating characteristic (ROC) curve indicated that the area under the curve (AUC) for serum POSTN level in predicting low bone mineral density in MHD patients was 0.901, with a cut-off value of 29.66 ng/L. Conclusion MHD patients have higher serum POSTN levels than healthy individuals, and this marker is associated with low bone mineral density in MHD patients.

Objective:To explore the clinical characteristics and medical nutritional therapy of 6 patients with late-onset ornithine transcarbamylase (OTC) deficiency.Methods:The clinical features, biochemical data, gene variations and treatment outcomes of 6 children with late-onset OTC deficiency admitted to the Department of Clinical Nutrition, Children′s Hospital of Nanjing Medical University from January 2020 to April 2022 were retrospectively analyzed.The 6 patients were all intervened by a long-term medical nutrition management.Results:Liver dysfunction and hyperammonemia (172.1-348.0 μmol/L) were found in all the 6 children with late-onset OTC deficiency.Serum citrulline decreased in 3 patients (3.95-5.43 μmol/L). Three patients showed increased urine orotic acid (123.48-342.60 mmol/mol Cr). Urine uracil increased in 4 patients (106.77-1 207.26 mmol/mol Cr). Variations of the OTC gene [c.364G>C p. (E122Q), c.1028C>G p. (T343R), c.664-2(IVS6)A>C, c.635G>T p. (G212V), c.929_c.931delAAG p. (E310del), c.829C>T p. (R277W)] were identified in all patients.The 6 children were all managed by individualized medical nutrition program and followed up for a long time.During the follow-up period, 3 cases developed hypoproteinemia, acute metabolic crisis and growth retardation, 3 cases had normal growth and laboratory indicators, and 1 case received liver transplantation after 3 months of nutritional management. Conclusions:The clinical manifestations of OTC deficiency are non-specific.Blood amino acids, urine organic acids and genetic tests are important for the diagnosis.Long-term regular medical nutrition management is helpful to improve the prognosis and quality of life of children.

Objective:To explore the correlation between abdominal aortic calcification and serum cell division cycle 42 (CDC-42) in maintenance hemodialysis (MHD) patients, and to explore the influencing factors of them.Methods:A cross-sectional study was conducted in the Blood Purification Center of Qingdao Municipal Hospital,112 patients who underwent MHD for more than 6 months from October 2019 to March 2021 were selected. The abdominal aortic calcification score (ACCs) was calculated by reference to the abdominal lateral X flat tablets. According to AACS, 50 cases were divided into no and mild calcification group (0≤AACS<5 points) and 62 cases were divided into moderate and severe calcification group (AACS≥5 points). The level of serum CDC-42 was detected by enzyme linked immunosorbent assay (ELISA). Taking the median serum CDC-42 level as the boundary, 56 cases were divided into low CDC-42 group and high CDC-42 group. Spearman correlation analysis was used to analyze the correlation between indicators. The risk factors of elevated CDC-42 and abdominal aortic calcification in MHD patients were explored by multivariate logistic regression analysis, and the variables were included by entry method.Results:In 112 patients, 91 cases (81.25%, 91/112) had abdominal aortic calcification, and the median serum CDC-42 level was 466.56 (335.56,623.57) ng/L. CDC-42, AACs, age, dialysis age, diabetic nephropathy, glycosylated hemoglobin, alkaline phosphatase, parathormone and calcium in the no and mild calcification groups were 347.77 (291.20, 419.53) ng/L, 1.00 (0.00, 3.00) points, (57.18±6.25) years, 31.50 (15.00, 49.25) months, 34.00%(17/50), (6.63±0.97)%, 116.22 (87.32, 152.13) U/L, 258.57 (143.40, 433.31) ng/L, (2.18±0.26) mmol/L, and in the moderate to severe calcification group were 602.69 (489.61, 762.73) ng/L, 10.00 (7.00, 16.25) points, (60.81±7.12) years, 49.00 (18.00, 67.00) months, 53.23%(33/62), (7.07±1.20)%, 144.34 (99.71, 201.76) U/L, 336.57 (230.63, 506.00) ng/L,(2.28±0.26) mmol/L, with statistically significant differences between the two groups(The statistical values were 6.99, 9.11, 2.83, 2.45, 4.14, 2.08, 2.04, 2.16 and 1.99, respectively, all P<0.05). CDC-42, AACs, glycosylated hemoglobin and parathormone in the low CDC-42 group were 336.50 (295.10, 395.25) ng/L, 2.00 (0.00, 4.00) points, (6.62±1.06) %, 250.60 (140.20, 462.02) ng/L,and in the high CDC-42 group were 622.92 (558.11, 836.65) ng/L, 10.00 (6.25, 15.75) points, (7.13±1.13) %, 347.21 (240.40,501.20) ng/L, with statistically significant differences between the two groups (The statistical values are 6.51, 5.21, 2.43 and 2.54, respectively,all P<0.05). Abdominal aortic calcification has positive correlations with CDC-42 ( r s=0.704, P<0.001), age ( r s=0.308, P=0.001), dialysis years ( r s=0.198, P=0.036), glycosylated hemoglobin ( r s=0.358, P<0.001), alkaline phosphatase ( r s=0.187, P=0.048), parathormone ( r s=0.437, P<0.001), serum calciu m( r s=0.323, P=0.001) and serum phospho-rus ( r s=0.251, P=0.007), and negative correlation with serum albumin( r s=-0.276, P=0.003). This study has confirmed that high serum CDC-42 ( OR=1.010, 95%CI:1.004-1.016, P=0.001) and senior dialysis age ( OR=1.033, 95%CI:1.006-1.061, P=0.018) were independent risk factors for moderate to severe abdominal aortic calcification.Serum CDC-42 levels has positive correlation with AACs ( r s=0.704, P<0.001), age ( r s=0.240, P=0.011), dialysis age ( r s=0.191, P=0.044), glycosylated hemoglobin ( r s=0.350, P<0.001), parathormone ( r s=0.380, P<0.001) and serum calcium ( r s=0.235, P=0.013). This study learned that,high AACs ( OR=1.185, 95%CI:1.037-1.354, P=0.013) and high parathormone ( OR=1.005, 95%CI:1.001-1.009, P=0.009) were independent risk factors for high CDC-42. The area under the receiver operating characteristic curve (ROC-AUC) of serum CDC-42 in predicting moderate and severe abdominal aortic calcification in MHD patients was 0.885. When the cut-off point was 466.56 ng/L, the predictive sensitivity and specificity were 79% and 86% respectively. Conclusion:The degree of abdominal aortic calcification in MHD patients was positively correlated with the level of serum CDC-42. High serum CDC-42 and high dialysis age were independent risk factors for abdominal aortic calcification in MHD patients. High AACS and high parathyroid hormone were independent risk factors for the increase of serum CDC-42 in MHD patients .

Objective To investigate the nutritional risk of hospitalized infants with severe pneumonia and its relationship with clinical outcome. Methods Totally 113 infants with severe pneumonia admitted to pediatric intensive care unit (PICU)were enrolled in the study. Nutritional risks were screened by STRONGkids, and the nutritional were assessment with WHO Anthro. Clinical outcomes were recorded and analyzed, including mechanical ventilation, length of PICU stay, total hospital expenses, prognosis, and biochemical test index. Results A total of 44 infants (38.9％) had high nutritional risk, 49 (43.4％) had medium nutritional risk, 20 (17.7％) had low nutritional risk when they admitted to PICU. A total of 59 (52.2％) infants were malnourished when they admitted to PICU. There was a significant correlation between the degree of malnutrition and nutritional risk (r =0.574, P<0.01).The incidence of high nutritional risk was significantly higher in 28d～1year-old group than in 1～3 year-old group (χ2=20.46, P<0.01). Nearly 42.5％(48/113) of the children had congenital disease and had higher incidence of high nutritional risk (χ2=11.375, P=0.003) and higher incidence of malnutrition (χ2=10.083, P=0.001) than those without congenital disease. The rate of mechanical ventilation (P=0.028), the duration of mechanical ventilation (P<0.01), total hospital expenses (P=0.002) and the incidence of poor prognosis(P=0.014) were significantly higher in high nutritional risk group than the low nutritional risk group. The retinol binding protein in the high nutrition risk group was significantly lower than the low nutrition risk group (χ2=6.333, P=0.021). Conclusions High nutritional risk and malnutrition are common in infants with severe pneumonia. Malnutrition and nutritional risk are increased in patients less than 1 year old or suffering from congenital disease. Patients with high nutritional risk are more likely to have worse clinical outcomes. STRONGkids is a valid tool for nutritional risk screening in hospitalized children, and early nutrition support is recommended.

Objective To investigate the nutritional status and the clinical outcome of the critically ill chil-dren,and to provide scientific evidence for further clinical nutrition management. Methods Nutritional risk screening was performed on 1183 critically ill children hospitalized at the Intensive Care Unit (ICU),Children′s Hospital of Nanjing Medical University from October 2016 to October 2017 by using the Screening Tool for Risk on Nutritional Sta-tus and Growth (STRONGkids),the ICU including of Pediatric Intensive Care Unit (PICU),Surgical Intensive Care Unit (SICU)and Coronary Care Unit (CCU). Median age of the children was (2. 6 ± 2. 4)years (29 d - 12. 9 years). Nutritional status was estimated,and scores of anthropometric parameters such as weight - for - age Z - score (WAZ)(< 5 years)or body mass index - for - age Z - score (BAZ)(≥5 years)were calculated. The data on inci-dence of infectious complications,duration of ICU stay and mechanical ventilation,the total hospital expenses and in -hospital mortality were recorded. Results Of the 1183 cases,134 children(11. 3％)had low nutritional risk,746 children(63. 1％)had moderate nutritional risk and 303 children(25. 6％)high nutritional risk. The prevalence of se-vere malnutrition,moderate malnutrition and mild malnutrition was 8. 1％ (96 / 1183 cases),8. 2％ (97 / 1183 ca-ses),and 12. 8％ (151 / 1183 cases)respectively. The severe malnutrition group had a higher incidence of high nutri-tional risk than other groups [74. 0％(71 / 96 cases)vs. 67. 0％(65 / 97 cases),40. 4％(61/ 151 cases),12. 6％(106/839 cases)],and the differe-nce was statistically significant (P < 0. 001). The incidence of high nutritional risk in the CCU was higher than that than that in the PICU and SICU,and the difference was statistically significant [36. 5％(96 /263 cases),23. 8％(125 / 524 cases)and 20. 7％(82 / 396 cases)respectively,P < 0. 01]. And the incidence of high nutritional risk was higher in infants[37. 6％(198 / 527 cases)]than those in the other age groups[18. 4％(52 / 282 cases),12. 0％(21 / 175 cases),16. 0％(32 / 199 cases)],and the difference was statistically significant (χ2 = 68. 90, P < 0. 0001). Children with a high nutritional risk had increased incidence of infectious complications [8. 6％(26 / 303 cases)vs. 4. 7％ (35 / 746 cases),3. 7％ (5 / 134 cases)],incidence of mechanical ventilation [66. 0％ (200 / 303 cases)vs. 41. 4％(309 / 746 cases),38. 8％(52 / 134 cases)]and total hospital expenses (￥ 52500 vs. ￥ 39700 and￥ 48700 RMB)compared with those with the moderate or the low nutritional risk,and the differences were statistically significant(all P < 0. 05). There were 16 deaths and 8 deaths (2. 7％)in the high nutrition risk group,which was sig-nificantly higher than those in the moderate nutrition risk group [8 cases (1. 1％)]and the low nutrition risk group [0 case(0)](χ2 = 7. 60,P = 0. 02). Conclusions Moderate or high nutritional risk is seen in the critically ill chil-dren,especially in infants and the children with congenital heart disease. Nutritional risk score is correlated with clinical outcomes. Nutritional risk screening and standard nutritional support are recommended so as to improve clinical treat-ment outcomes.
