ABSTRACT

Objective:To investigate the effects of beginning time of intermittent pneumatic compression (IPC) on hemodynamics and deep vein thrombosis (DVT) of patients with major orthopedic surgery.Methods:A total of 99 patients who underwent major orthopaedic surgery in the Department of Orthopaedics, West China Hospital, Sichuan University from January 2018 to December 2019 were selected as the research objects, which were assigned to ultra-early group, early group and control group, each group contained 33 cases. The IPC were used 3 days before surgery in the ultra-early group, 1 day before surgery in the early group, and after surgery in control group. The incidence of DVT and deep skin pressure injury within 14 days was observed, the blood flow velocity of deep femoral vein and plasma D-dimer in the three groups were also compared.Results:There was no significant difference in the incidence of DVT among the three groups ( P> 0.05), however, the deep tissue injury rate was 18.18% (6/33) in the ultra-early group, significantly higher than 3.03% (1/33) in the early group and 0 in control group, the difference was statistically significant ( χ2 value was 9.531, P<0.05). After 1 day and 3, 5, 7 days of surgery, the blood flow velocity of deep femoral vein in the ultra-early group and the early group were (26.48±2.24), (25.79±2.18), (26.67±3.74), (25.88±2.83) ml/s and (25.76±1.87), (25.39±1.98), (25.45±2.93), (25.48±3.75) ml/s, significantly higher than (23.39±1.75), (23.73±2.61), (23.79±2.30), (22.21±4.42) ml/s in the control group, the difference was statistically significant ( F values were 7.428-22.350, P<0.01). After 3, 5, 7 days of surgery, the levels of plasma D-dimer in the ultra-early group and the early group were (1.11±0.26), (1.03±0.23), (0.98±0.28) mg/L and (1.18±0.32), (1.12±0.24), (1.05±0.31) mg/L, significantly lower than (1.38±0.40), (1.32±0.39), (1.20±0.26) mg/L in the control group, the difference was statistically significant ( F values were 5.809, 8.442, 4.962, P<0.01). Conclusion:Using IPC one day before operation can significantly increase the blood flow velocity of deep femoral vein, reduce the level of plasma D-dimer, and do not increase the incidence of deep skin pressure injury in patients with major orthopedic surgery.

ABSTRACT

Objective:To explore the clinical manifestations and surgical outcomes of pediatric epilepsy patients with epileptic spasms (ES) as the main form of seizure, so as to analyze the correlative factors with prognosis and improve the understanding of the operation and preoperative positioning for such patients.Methods:The clinical data of patients with ES who underwent surgery therapy from June 2014 to December 2015 in Pediatric Epilepsy Center, Peking University First Hospital were collected and retrospectively analyzed.Demographic characteristics, seizure forms, etiology, electroencephalogram (EEG), cranial magnetic resonance imaging (MRI), operative methods, pathological findings as well as surgical outcomes evaluated by Engel classification during follow-up of the subjects were collected.Correlative factors with the prognosis were explored by comparing the data between patients with optimal outcome (Engel Ⅰ) and those with poor outcomes (Engel Ⅱ-Ⅳ).Results:A total of 25 pediatric patients were enrolled, including 16 males (64.0%) and 9 females (36.0%). The age of onset was (0.81±0.68) years, the age at operation was (2.98±1.63) years, and the course of disease was (2.17±1.48) years.Besides, 84.0% (21/25 cases) of the ES patients had multiple forms of seizures and partial seizure (19 cases) was the most common.MRI of the heads of all the children showed definite lesions, including 11 patients (44.0%) with lesions limited to one brain lobe and 14 patients (56.0%) involving multiple brain lobes or hemisphere.The most common etiology was focal cortical dysplasia (13 cases), followed by intracranial developmental tumors (3 cases). All patients underwent resection surgery, including resection of lesion (3 cases), single brain lobe resection (9 cases), multiple brain lobe dissection (3 cases) and hemisphere dissection (10 cases). During a follow-up period of 4.0 to 5.5 years, 1 patient was lost.Among the remaining 24 cases, 18 (75.0%) cases achieved good outcomes and wee classified as EngelⅠ, 2 cases (8.3%) and 4 cases(16.7%) were classified as Engel Ⅱand Ⅳ, respectively.The univariate comparison between the good epilepsy prognosis group and the poor epilepsy prognosis group showed that, patients whose EEG abnormalities are consistent with the anatomical lesions during the inter ictal tend to have good prognosis( P=0.006). Conclusions:(1) Optimal therapeutic effects were observed in ES patients with definite lesions treated by surgical therapy.(2) Interictal EEG consistent with the lesion side may suggest a good prognosis for surgical treatment.(3) Structural causes should be screened as soon as possible if a patient with ES is drug-refractory and presents clues of focal origin.

ABSTRACT

Objective@#To examine the effects of parental rearing style and its consistency on sleep problems of preschool children and to provide theoretical basis for making early family intervention measures.@*Methods@#A questionnaire survey was conducted among 2 744 children and their parents in 19 kindergartens in Anqing city. Parental Behavior Inventory (PBI) was used to investigate the rearing style of parents, and Chinese version of Children s Sleep Habit Questionnaire (CSHQ) was used to evaluate the incidence of sleep among preschoolers.@*Results@#Preschool children s overall rate of sleep disorder was 15.5%, and accompanied by sleep duration disorder (70.0%), sleep resistance (64.2%), sleep latency (38.7%), anxiety (15.5%), daytime sleepiness ( 10.1 %). Living in urban areas, parents smoking and drinking behaviors, and parents parenting style all affected preschoolers sleep ( P <0.05). Multivariate Logistic regression analysis showed that fathers active rearing style was negatively correlated with preschool children s sleep problems such as delayed sleep impedance and short sleep duration, while mothers active rearing style was negatively correlated with preschool children s sleep problems such as sleep resistance and night wake up ( P <0.05). There was a positive correlation between father s severe rearing style and preschoolers sleep resistance, sleep duration, short sleep disordered breathing, daytime sleepiness and total sleep problems, and mother s severe rearing style and preschoolers sleep duration, short sleep anxiety, night wakefulness, daytime sleepiness and total sleep problems ( P <0.05). Consistent rate of negative rearing patterns was a risk factor for short sleep duration in preschoolers ( OR =2.19,95% CI =1.12-4.28, P =0.02).@*Conclusion@#The detection rate of sleep problems in preschoolers is high. Parental supportive involvement has a positive effect on preschoolers sleep, while parental coercion hostile parenting has a negative effect on preschoolers sleep. The consistent rate of rearing styles affects the sleep duration of preschoolers.

ABSTRACT

Objective To explore the effects of Humulus lupulus L. extract (HLE) and its mechanism on improving bone formation of Aβ-injured osteoblasts. Methods Osteoblasts isolated from 24 h-old Wistar rats were injured by Aβ1-42 oligomer and intervened with HLE. The proliferation, differentiation and bone mineralization of osteoblasts were determined by MTT assay, alkaline phosphatase (ALP) activity assay and alizarin red staining, respectively. The apoptosis of osteoblasts was detected by flow cytometer. The expression levels of bone formation related proteins, and proteins of Nrf2 and FoxO1 pathways were measured by Western blotting analysis. The intranuclear expression of FoxO1 protein was detected by immunofluorescence. Results HLE significantly improved the cell proliferation, ALP activity and bone mineralization, and inhibited the apoptosis of Aβ-injured osteoblasts. HLE also significantly promoted the expressions of collagen type Ι (COL-I) and osteopontin (OPN) in Aβ-injured osteoblasts. HLE notably activated the Nrf2 and FoxO1 signaling pathways in Aβ-injured osteoblasts by promoting the expressions of related proteins and maintained bone metabolism through relieving oxidative stress. Conclusion This study confirms that HLE can alleviate Aβ-injury to osteoblasts, and preliminarily clarifies the mechanism being related to antioxidation, which provides a new reference for the mechanism research and drugs development for anti-osteoporosis.

ABSTRACT

Objective To study the correlation of plasma homocysteine (Hcy) levels with the gene polymorphisms of homocysteine metabolic enzymes in physical examination in Nan Chong. Methods A cross-sectional study design was adopted. A total of 470 Han people who received physical examination in the outpatient clinic of Nanchong Central Hospital were enrolled in this study. Blood samples were collected from the research subjects, and general clinical data of the subjects were collected. The plasma Hcy level was determined by a commercial homocysteine assay kit. Genomic DNA was extracted, and a newly-developed technology (improved Multiplex Ligation Detection Reaction, iMLDR) was used to detect target genes and SNPs. The gene polymorphism of Hcy metabolism enzymes MTHFR C677T, MTHFR A1298C, MTR A2756G, and MTRR A66G was detected, and its correlation with plasma levels of Hcy was analyzed. Results (1) The distribution frequency of the heterozygous genotype of MTHFR C677T, MTHFR A1298C, MTR A2756G, and MTRR A66G was 46.38%, 35.32%, 17.45%, and 40.85%, while the distribution frequency of the homozygous genotype was 12.13%, 4.04%, 1.49%, and 7.66%, respectively. There was no statistically significant difference in allele frequencies between male and female populations by chi-square test (2) The detection rate of hyperhomocysteinemia (HHcy) was 34.68%. There was significant difference in the levels of plasma Hcy among the three genotypes of MTHFR C677T, and the heterozygous genotype and homozygous genotype of MTHFR C677T increased the risk of HHcy by 2.97 times and 1.917 times, respectively. The genotypes of MTHFR A1298C, MTR A2756G, and MTRR A66G were not found to be correlated with the risk of HHcy. Conclusion MTHFR C677T CT and TT genotypes elevate the plasma Hcy level. The gene polymorphisms of MTHFR A1298C, MS A2756G and MTRR A66G are not risk factors for HHcy.

ABSTRACT

ObjectiveTo investigate the clinical features of infection in patients with acute-on-chronic liver failure (ACLF) and bacterial infection and the influencing factors for 90-day survival rate. MethodsThe patients with ACLF who were admitted to The Fifth Medical Center of Chinese PLA General Hospital from January 2014 to December 2015 were enrolled, and related clinical data were collected and analyzed, including infection time and site, microbial culture, biochemical parameters and inflammatory markers, and 28- and 90-day prognosis after infection. The t-test or the Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. The life-table method was used to plot survival curves. The indices affecting prognosis in the univariate analysis were further included in the multivariate logistic regression analysis. ResultsA total of 1074 patients with ACLF were admitted, among whom 609 had bacterial infection, and the incidence rate of bacterial infection was 567%. Among these 609 patients, 16 underwent liver transplantation within 90 days and related data statistics were obtained for the remaining 593 patients. As for infection site, among the patients with infection, 70.15% had abdominal infection, 41.15% had pulmonary infection, 11.97% had sepsis, 5.40% had urinary system infection, 4.89% had thoracic infection, and 8.6% had infection at other sites. Among the patients with infection, 64.76% had infection at a single site. The positive rates of microbial culture of ascites, phlegm, urine, and pleural effusion were 22.70%, 52.82%, 40.63%, and 35.71%, respectively. Escherichia coli was the most common bacterium in ascites and accounted for 43.82%; Klebsiella pneumoniae, Pseudomonas aeruginosa, and Acinetobacter baumannii accounted for 22.67%, 2400%, and 22.67%, respectively, in phlegm; Escherichia coli, Klebsiella pneumoniae, and Staphylococcaceae accounted for 33.80%, 29.58%, and 15.49%, respectively, in blood culture. The 90-day survival rate after infection was 38.11% (226/593) in the patients with ACLF, and the multivariate logistic regression analysis showed that age (P=0.006), stage of hepatic encephalopathy (HE) (P<0001), stage of liver failure (P<0.001), and acute kidney injury (AKI) (P<0.001) were independent risk factors for 90-day survival in patients with ACLF and infection. ConclusionThere is a high incidence rate of infection in patients with ACLF. The 90-day survival rate is relatively low, and the presence of AKI, HE stage III or above, and advanced liver failure may indicate poor prognosis.

ABSTRACT

BACKGROUND@#The study aimed to explore the factors influencing protective behavior and its association with factors during the post-COVID-19 period in China based on the risk perception emotion model and the protective action decision model (PADM).@*METHODS@#A total of 2830 valid questionnaires were collected as data for empirical analysis via network sampling in China. Structural equation modeling (SEM) was performed to explore the relationships between the latent variables.@*RESULTS@#SEM indicated that social emotion significantly positively affected protective behavior and intention. Protective behavioral intention had significant direct effects on protective behavior, and the direct effects were also the largest. Government trust did not have a significant effect on protective behavior but did have a significant indirect effect. Moreover, it was found that government trust had the greatest direct effect on social emotion. In addition, we found that excessive risk perception level may directly reduce people's intention and frequency of engaging in protective behavior, which was not conducive to positive, protective behavior.@*CONCLUSION@#In the post-COVID-19 period, theoretical framework constructed in this study can be used to evaluate people's protective behavior. The government should strengthen its information-sharing and interaction with the public, enhance people's trust in the government, create a positive social mood, appropriately regulate people's risk perception, and, finally, maintain a positive attitude and intent of protection.

ABSTRACT

Objective@#To understand changes and characteristics of bone mineral density(BMD)and early-stage bone turnover biochemical markers in elderly hip fracture patients of different genders.@*Methods@#This was a retrospective cohort study.A total of 1 161 elderly patients with hip fractures hospitalized in Beijing Jishuitan Hospital from May 2015 to December 2017 were enrolled.Based on gender, patients were divided into the female group(n=831)and the male group(n=330). Clinical data, BMD, serum type I procollagen amino terminal propeptide(P1NP), and 25-hydroxyvitamin D3 [25-(OH)VD3], type I collagen cross-linked carboxy terminal peptide beta degradation products(β-CTX), osteocalcin(OC)and parathyroid hormone(PTH)were measured and compared between the two groups.@*Results@#Of the 1 161 elderly patients with hip fractures, 831 were female and 330 were male.The BMD of the lumbar vertebrae and the total hip in the female and male groups showed that 30.4%(353/1 161)and 6.8%(79/1 161)had T≥-1.0 SD respectively; 36.6%(425/1 161)and 44.7%(519/1 161)had -2.5 SD<T<-1.0 SD; and 33.0%(383/1 161)and 48.5%(563/1 161)had T≤-2.5 SD respectively.The sensitivity of the hip BMD T value was better than that of lumbar vertebrae(P<0.05). Female BMD was significantly lower than that of male BMD(P<0.05). The BMD T values, which were significantly related to age, were recorded at the femoral neck and the total hip(femoral neck was better than total hip)for males and at total hip(the total hip T value is the most strongly related index)for females; (2)In the early stage of elderly hip fractures, 25-(OH)VD3 was significantly lower than normal, and bone resorption and bone formation indexes were not significantly increased(P>0.05). The levels of tP1NP, β-CTX, OC and PTH in females were higher than those in males, and the level of 25-(OH)VD3 was lower than that in males(all P<0.05). As the T value decreased, β-CTX and OC increased and 25-(OH)VD3 decreased accordingly(all P<0.05).@*Conclusions@#With the increase of age, the BMD T value in elderly patients with hip fractures shows a downward trend, but its decline in women is faster and earlier.Overall, the BMD T value is not sensitive enough for osteoporosis diagnosis or hip fracture prediction in the elderly, especially in men.In the early stage of fractures, the bone turnover biochemical markers show varying degrees of change, and bone resorption and bone formation are both reduced.The significance of OC, β-CTX and VD levels in early bone metabolic abnormalities requires further study.

ABSTRACT

Objective:To analyze the effect of pregnancy with adenomyosis on perinatal outcome.Methods:From April 2014 to April 2019, singleton pregnant women complicated with adenomyosis in Peking University Third Hospital was selected and the perinatal outcomes were analyzed retrospectively.Results:The age of patients in the pregnancy with adenomyosis group (study group) was not different from that of the control group (median: 35 vs 34 years old, P>0.05); the body mass index was higher than that of the control group (median: 23.9 vs 21.8 kg/m 2, P<0.01); the rate of assisted reproductive technology was significantly higher than that of the control group [25.3% (64/253) vs 3.1% (8/257), P<0.01]. Compared with the control group, the gestational age at delivery was significantly lower in the study group (median: 38.0 vs 39.2 weeks, P<0.01); the rates of preterm birth [17.1% (44/257) vs 4.7% (12/257), P<0.01] and preeclampsia [13.7% (35/255) vs 5.8% (15/257), P=0.003] were significantly higher in the study group. The incidence of severe postpartum hemorrhage in the study group was significantly higher than that in the control group [5.8% (14/241) vs 1.2% (3/257), P=0.004]. The incidence of cesarean section was higher in the study group [(57.0% (146/256) vs 31.5% (81/257), P<0.01]. Neonatal weight was lower in the study group than that in the control group (median: 3 140 vs 3 440 g, P<0.01); the incidence of small for gestational age (SGA) was higher in the study group [21.5% (55/256) vs 4.7% (12/257), P<0.01]. There were no significant differences in umbilical artery pH and 1-minute Apgar score between the study group and the control group (all P>0.05). Conclusions:Pregnant women complicated with adenomyosis has low fertility, and most of them need assisted reproductive technology to conceive. The pregnant women with adenomyosis has the poor perinatal outcome, including an increased incedence of preterm birth, preeclampsia, postpartum hemorrhage, cesarean section and SGA, and low newborn weight.

ABSTRACT

Objective:To investigate the clinical characteristics, surgical methods, complications and prognosis of children younger than 1 year old who had definite epileptogenic lesions under 1 year old.Methods:A total of 14 children with definite epileptogenic lesions and underwent radical surgery in Pediatric Epilepsy Center of Peking University First Hospital from March 2017 to July 2019 were selected.Their clinical data including operation age, course of disease, etiology, physical examinations, seizure types, seizure frequency, features of interictal electrocorticography(EEG), surgical methods, antiepileptic drugs, and pathology were collected and analyzed.Postoperative efficacy was eva-luated using Engel grading.The Griffiths neurodevelopmental scale and the Peabody motor developmental scale were used to assess motor neurodevelopment.Results:The operation age of 14 children was 119 to 358 days (median: 281 days), and the course of disease ranged from 119 to 352 days (median: 266 days). The age of onset was from 0 to 135 days was (median: 7.5 days), and the postoperative follow-up time was 0.5-2.0 years(median: 1.5 years). None of the patients had seizure recurrence at the last follow-up.During the follow-up period, 1 patient had recurrence, but deve-loped no seizures anymore after drug administration.Cognitive and motor functions improved during follow-up in all children.All the children had no serious complications such as postoperative infection and hydrocephalus.Conclusions:Young children with definite epileptogenic lesions have an early onset of seizures, which has a great influence on development.Multidisciplinary preoperative evaluation shows that surgery is a safe way to terminate progression of seizures, thus helping children to well develop and reducing the use of antiepileptic drugs.

ABSTRACT

Hypertrophic cardiomyopathy(HCM)is a cardiac disease characterized by left ventricular cardiac hypertrophy, which is the most common hereditary cardiovascular disease, accounting for the second in childhood cardiomyopathy.Currently, drug therapy for HCM mainly includes beta blockers, calcium channel blockers, antiarrhythmic drugs and novel drugs, whose main effect is to delay symptoms.However, because the causes of HCM in children are more complex than in adults, so the treatment is more challenging.And the genetic metabolic defect is one of the most common causes of HCM in children.In view of this kind of etiology, drug therapy that mainly regulates metabolic abnormalities is more important.Some children with HCM can significantly improve cardiac function and even reverse cardiomyopathy through early intervention.Here we review the progress of drug therapy for HCM in children.

ABSTRACT

Pediatric dilated cardiomyopathy(DCM)is a myocardial disorder characterized by a dilated left ventricular chamber and systolic dysfunction that often manifested as heart failure, arrhythmia, thrombosis, thromboembolism and sudden death.Survival free from transplantation was 54%-72% 5 years after diagnosis, and 46%-62% at 10 years.Several factors indicating better prognosis are higher left ventricular ejection fraction, and the presence of myocarditis.Other predictors such as older age at diagnosis, a family history of cardiomyopathy, arrhythmias, severe mitral regurgitation, lager left ventricular end-diastolic dimension and end-systolic dimension, and cardiothoracic ratio greater than 65% suggest that the prognosis may be poor.The cornerstone of pediatric DCM therapy is drug therapy including angiotensin-converting enzyme inhibitors, β-blockers and aldosterone antagonists.Ivabradine, myocardial metabolic drugs and intravenous immunoglobulins may be associated with better improvement of systolic left ventricular function.

ABSTRACT

Objective:To analyze the difference in skin surface lipids (SSL) between facial skin lesions of neonates with acne and normal facial skin of healthy infants.Methods:SSL samples were collected from facial skin lesions of 36 neonates with acne (acne group) and normal facial skin of 36 healthy infants (control group) at the Department of Dermatology, Children′s Hospital, Capital Institute of Pediatrics from June 2018 to August 2018. A lipid map was constructed by ultra-performance liquid chromatography-quadrupole-time of flight-mass spectrometry (UPLC-QTOF-MS), and specific information about lipid components was obtained by multivariate data analysis. Independent-sample t test was performed with SPSS19.0 software for comparisons between 2 groups. Results:Compared with the control group, the acne group showed significantly increased relative content of glycerolipids and prenol lipids on the facial skin surface (both P < 0.001), but significantly decreased relative content of fatty acids, glycerophospholipids, sphingolipids, sterol lipids, saccharolipids and polyketides ( P < 0.01 or 0.05) .Further analysis showed that the average relative content of total lipids, diglycerides, wax esters and squalene was significantly higher in the acne group than in the control group ( P < 0.001 or 0.05), but the average relative content of linoleic acid was significantly lower in the acne group than in the control group ( P < 0.001) . Conclusion:Compared with the facial skin of healthy infants, the facial skin lesions of neonates with acne showed significantly increased total lipid content and different lipid components.

ABSTRACT

Objective:To investigate cutaneous sequelae of neonatal lupus erythematosus (NLE), and to analyze possible related factors.Methods:A total of 13 NLE patients with long-term follow-up were collected from Department of Dermatology, Children′s Hospital Affiliated to Capital Institute of Pediatrics from 2016 to 2020, and clinical manifestations and cutaneous sequelae of these patients, as well as clinical manifestations of their mothers, were retrospectively analyzed.Results:Skin lesions occurred in the 13 patients within 120 days after birth, with an average onset time of 15 days, and the follow-up duration ranged from 15 to 43 months. Skin lesions mainly manifested as annular erythema, maculopapules and scales, and subsided within 2 - 18 months (average, 7.4 months). Pigmentation abnormalities occurred in 6 cases after subsidence of skin lesions, including 3 with both hypopigmentation and hyperpigmentation, 2 with hypopigmentation alone, and 1 with hyperpigmentation alone. One patient with hypopigmentation achieved repigmentation after 18 months of follow-up, and no telangiectasia, atrophy or scars were observed. No abnormalities were observed in the mothers of 8 patients before pregnancy, and the mothers of 4 patients were positive for antinuclear antibody, anti-SSA/Ro antibody and anti-SSB/La antibody.Conclusions:Cutaneous sequelae can occur after skin involvement of NLE, and mainly includes pigmentation abnormalities, most of which can not subside after a long time. Attention should be paid to potential immune system abnormalities in the mothers of patients with NLE.
