ABSTRACT
Type 1 diabetes mellitus(T1DM)is a disease that seriously harms children′s health.It often occurs in childhood and is a major public health problem all over the world.T1DM can cause damage to multiple systems including nervous, circulatory, urinary systems, etc.The etiology, prevention and treatment of T1DM have become a research hotspot.With the deepening of researches, the influence of T1DM on cognitive function in children has attracted increasing attention.T1DM can damage the brain structure, neurological development and cognitive function of children, influencing intelligence, attention, memory, executive function, etc.This paper reviews the recent researches between T1DM and cognitive function of children, so as to improve the awareness of pediatricians.
ABSTRACT
Objective To summarize the clinical data of macrophage activation syndrome (MAS) in adult-onset Still's disease (AOSD) patients and provide evidence for clinical diagnosis and treatment. Methods We retrospectively reviewed the clinical data of AOSD with MAS patients in the First Affiliated Hospital of Zhengzhou University from January 2012 to August 2018, and compared with patients with AOSD alone. Data were analyzed by t-test, Mann-Whitney U test, x2 test or Fisher exact test. Results A total of 14 AOSD with MAS patients were enrolled, accounting for 7.6％(14/185) of AOSD patients at the same period, including 2 males and 12 females. The median duration of AOSD in MAS was 1.3 (0.25, 4) months. Compared with the AOSD group, the age of onset was younger in the MAS group (t=-2.038, P=0.037), and the proportion of splenomegaly (t=9.020, P=0.003), pericardial effusion (t=8.663, P=0.003), pleural effusion (t=4.754, P=0.029) was higher. The white blood cell count (t=-4.171, P<0.01), hemoglobin level (t=-2.661, P=0.008), platelet count (t=-5.672, P<0.01), neutrophil count (t=-5.082, P<0.01), albumin (t=-3.426, P<0.01), fibrinogen (t=-5.986, P<0.01), ESR (t=-2.941, P=0.003), CRP (t=-2.014, P=0.044) was significantly decreased, ALT (t=-3.227, P<0.01), AST (t=-3.105, P=0.002), triglyceride (t=-5.612, P<0.01), ferritin>2000 μg/L (t=7.833, P=0.005) was significantly increased. Fourteen patients with AOSD complicated with MAS were treated with glucocorticosteroids, 5 with methylprednisolone, 8 with cyclosporine A, 8 with intravenous immunoglobulin (IVIG), 2 with etoposide, and 1 with tocilizumab. After treatment, 11 cases recovered and 3 cases died. Conclusion Younger AOSD patients tend to complicated with MAS, especially at the early course of the disease, and splenomegaly occur more frequently clinically compared to patients without MAS. When blood cell count, fibrinogen and ESR decreases, triglyceride and ferritin levels increases in AOSD patients, the occurrence of MAS is indicated. Timely treatment can improve the prognosis of patients.
ABSTRACT
Objective To investigate the health related quality of life score [primary biliary cholangitis (PBC)-40] in patients with PBC,and the relationship between PBC-40 and clinical presentations.Methods The PBC-40 score and clinical presentations in PBC patients (n=65) were adapted in this study.Patients were divided into the untreated group and the treated group,and the treated group was further divided into ursodesoxycholic acid (UDCA) response group and UDCA non-response group.PBC-40 scores of different groups were analyzed by t-test and the relationship between PBC-40 and clinical presentations were analyzed with Pearson's test.Results Dimensions of PBC-40 scores of this group of patients were as follows:symptoms were (15.8±4.1) points,itch was (4.9±2.8) points,atigue was (23.8±8.9) points,cognitive dysfunction score was (11.4±4.7) points,social activity score was (17.0±7.5) points,and the emotion score was (6.5±3.1) points.The untreated group had higher emotion scores than the treated group (t=2.024,P=0.045).Compared with the UDCA response group,UDCA non-response group had higher scores in cognitive,social and emotion dimension (t =2.126,2.309,2.062,respectively,P=0.039,0.025,0.045,respectively).Itch score was significantly correlated with total bilirubin (TBil),direct bilirubin (DBil),alkaline phosphatase (ALP) and total bile acid (TBA) (r=0.349,0.345,0.324,0.427,respectively,P＜0.01),while the social scores were correlated with TBil,DBil,aspartate aminotransferase (AST) and TBA (r=0.361,0.383,0.316,0.331,P＜0.01) and emotion scores were associated with ALT,TBil,GGT,ALP,AST and TBA (r=0.332,0.430,0.265,0.326,0.297,0.353,P＜0.05).ConclusionPBC-40 can be used as a health-related quality of life assessment for PBC patients inChinese population.Itch,social and emotion dimensions are correlated with clinical activity indicators.Hyperbilirubin,ALP and TBA can predict low health quality of life in PBC patients.Conclusion PBC-40 can be used as a health-related quality of life assessment for PBC patients in Chinese population.Itch,social and emotion dimensions are correlated with clinical activity indicators.Hyperbilirubin,ALP and TBA can predict low health related quality of life in PBC patients.
ABSTRACT
Objective@#To analyze the clinical features of dyslipidemia in patients with primary biliary cholangitis (PBC).@*Methods@#The clinical and laboratory data of 136 PBC patients in Peking Union Medical College Hospital from 2010 to 2016 were retrospectively analyzed.The liver function was compared between patients with normal and abnormal blood lipids.@*Results@#Among 136 PBC patients, 100(74%)had abnormal serum lipids. The incidence of increased cholesterol, low-density lipoprotein and triglyceride was 61%(59/96), 58%(48/83) and 47%(46/97), respectively; while that of reduced HDL-C was 26%(21/82). The incidences of pruritus [26%(26/100) vs. 8%(3/36), χ2=4.93, P=0.032], serum total bilirubin (TBIL) [17.3(12.2, 28.2) μmol/L vs. 14.5 (9.4, 21.1) μmol/L, Z=2.25, P=0.024], direct bilirubin (DBIL)[5. 5 (3.4, 12.4) μmol/L vs. 4.4(2.9, 7.1) μmol/L, Z=2.00, P=0.045], and glutamyl aminotransferase (GGT)[193.0(64.3, 454.8)U/L vs. 105.5(53.5, 179.5)U/L, Z=2.02, P=0.043], alkaline phosphatase(ALP)[183(86, 351)U/L vs. 135(85, 188) U/L, Z=1.98, P=0.048] in PBC patients with dyslipidemia were significantly higher than thosein patients with normal serum lipids.Pearson regression analysis showed that in PBC patients with dyslipidemia, the ALT was positively corrected with TG and TC(r=0.248 and 0.272, P=0.015 and 0.008); ALB was positively correlated with LDL-C(r=0.335, P=0.002); DBIL was positively corrected with HDL-C(r=0.252, P=0.022); TC was positively correlated with ALP and GGT(r=0.313 and 0.346, P=0.002 and 0.001); GGT was positively correlated with LDL-C(r=0.251, P=0.022).@*Conslusion@#Increased TC and LDL-C were more common in PBC patients. PBC patients with dyslipidemia have more severe liver damage than the patients with normal serum lipids.
ABSTRACT
Objective To investigate the expression of programmed death receptor-1 (PD-1) in CD8+ T cells and FoxP3+CD4+ cells in patients with primary biliary cholangitis (PBC).Methods The peripheral blood and clinical data of 69 PBC patients in Peking Union Medical College Hospital and 58 health controls (HC) were collected.They were divided into initial treatment group and follow-up group according to whether they were treated or not.Patients in the treatment group were further divided into the refractory group and stable group according to treatment response.Flow cytometry was used to detect the expression of PD-1 in CDS+T cells and FoxP3+CD4+ cells.T-test and Person correlation analysis were used for data analysis.Results The PD-1 expression in peripheral blood mononuclear cells (PBMCs) of 69 PBC patients (12±9)％ was lower than that of HC (20±12)％ (t=-3.687,P＜0.01).The percentage of PD-1+ in FoxP3+ CD4+T cells was significantly increased in PBC (5.6±3.7)％ than HC (7.4±2.4)％ (t=2.048,P＜0.01).The proportion of CD8+T cells,PD-1 expression in CD8+T cells and the proportion of FoxP3+CD4+ cells weren't correlated with clinical parameters (P＞0.05).There was a negative correlation between the expression of PD-1 cells in FoxP3+CD4+ cells and GLOBE score (r=-0.307,P＜0.05).Conclusion The expression of PD-1 in peripheral CD8+T lymphocytes of PBC patients is lower than that of HC,and decreases more significantly in the refractory group.The expression of PD-1 on FoxP3+CD4+T cells is higher than that in HC,and is negatively correlated with the prognostic GLOBE score.It suggests that PD-1/PD-L1 pathway participates in the immune mechanism of PBC.
ABSTRACT
Objective To investigate the application of 3D printing technique in the treatment of obsolete pelvic and acetabular fractures.Methods The clinical data of 23 patients with obsolete pelvic and acetabular fractures were retrospectively analyzed who had been surgically treated in our hospital from January 2006 through January 2016.3D printing technique was used in surgical planning in 11 of them,including 8 males and 3 females,with an average age of 33.8 ±4.9 years (3D group).The other 12 patients received conventional surgery without using 3D printing technique.They were 9 males and 3 females,with an average age of 34.8 ± 8.3 years (conventional group).The primary pelvic fractures in both groups were all type C according to the Tile classification system.The patients complicated with acetabular fracture in the 3D group and the conventional group were 10 and 11 cases respectively.The operative time,blood loss,blood transfusion.intraoperative fluoroscopy,visual analogue score (VAS) and Majeed score were compared between the 2 groups.Results The 2 groups were compatible in terms of preoperative general data (P ＞ 0.05).For the 3D group and the conventional group,operative time was 166.4± 24.2 min versus 222.5 ± 49.0 min.blood loss 2,063.6 ± 484.3 mL versus 2,700.0 ± 597.0 mL,blood transfusion 13.2 ± 3.2 U versus 17.6 ± 4.5 U,and intraoperative fluoroscopy 7.4 ± 1.3 times versus 11.7 ± 3.6 times.There were significant differences between the 2 groups in the above indexes (P ＜ 0.05).The 3D group and the conventional group obtained an average follow-up of 18.4 months and 21.7 months,respectively.The postoperative VAS scores were respectively 1.8 ±-0.9 points and 3.4 ± 1.0 points for the 2 groups,showing a significant between-group difference (P ＜0.05).The Majeed scores at the last follow-ups were respectively 85.7 ± 4.2 points and 84.9 ± 3.1 points for the 2 groups,showing no significant between-group difference (P ＞ 0.05).There were no such complications in the 3D group as iatrogenic nerve injury,vascular injury,nonunion or internal fixation failure.One patient in the conventional group suffered transient iatrogenic injury to the sciatic nerve.Conclusions 3D printing technique can provide helpful guidance for diagnosis and fracture classification preoperatively.It improves the patient's perioperative safety by benefiting intraoperative reduction,shortening operative time,and reducing intraoperative blood loss and intraoperative fluoroscopy.
