ABSTRACT

Objective:To analyze the sleep quality and sleep structure of patients with obstructive sleep apnea hypopnea syndrome (OSAHS) complicated with patent foramen ovale (PFO), and to study the effect of PFO on the sleep structure of OSAHS.Methods:Fifty-six patients with OSAHS complicated with PFO, 64 patients with simple OSAHS and 62 controls were collected from December 2018 to March 2020 in Centre of Sleep Disorders, the Second Affiliated Hospital of Zhengzhou University. Pittsburgh Sleep Quality Index and polysomnography were used to compare the sleep quality and sleep structure of the three groups.Results:Compared with the control group [6/62(9.68%)], OSAHS complicated with PFO group [54/56(96.43%)] and simple OSAHS group [53/64(82.81%)] had higher incidence of poor sleep quality (χ2=112.08, P<0.0l). Furthermore, compared with the control group, the OSAHS complicated with PFO group and simple OSAHS group showed reduced sleep efficiency [PSQI total score was 0.5 (0, 1), 2 (1, 3) and 2 (1, 2) respectively, H=74.549, P<0.01] and reduced proportions of rapid eye movement (REM; 20.45%±3.49%, 12.19%±5.95% and 15.11%±7.21%,respectively, F=21.17, P<0.01) and slow wave sleep (N3; 21.24%±4.12%, 14.15%±6.08%, 17.68%±6.35%, respectively, F=29.51, P<0.01); the N1 (4.47%±2.40%, 9.50%±5.34%, 9.55%±4.61%, respectively, F=30.07, P<0.05) and N2 sleep (53.88%±4.35%, 64.09%±7.49%, 58.14%±6.67% , respectively, F=46.21, P<0.05) were prolonged; the inocturnal lowest oxyhemoglobin saturation (SpO 2) level was lower, mean SpO 2 reduction at night was higher [3.00% (0, 4.00%),6.00% (5.00%, 8.75%) and 4.00% (4.00%, 5.00%), respectively, H=72.24, P<0.05], and periodic leg movement index [16.30(4.80, 32.82), 33.30(9.26, 54.80) and 23.10(8.38, 31.83),respectively, H=17.86, P<0.05], arousal index [11.60(7.73, 17.55), 23.90(14.03, 30.45) and 15.6(11.23, 20.78), respectively, H=22.80, P<0.05] and sleep apnea and hypopnea index (AHI; 1.60±1.38, 23.90±7.27 and 16.24±4.22,respectively, F=136.97, P<0.05) increased. Compared with the simple OSAHS group, the incidence of poor sleep quality was higher, the proportions of slow wave sleep (N3, F=29.51, P=0.047) and REM ( F=21.17, P=0.012) were decreased, N2 sleep ( F=46.21, P=0.000) was prolonged, mean SpO 2 reduction at night ( Z=54.28, P=0.000), wake after sleep onset [116.00(89.88, 143.00) min vs 135.00(118.50, 168.38) min, Z=25.71, P=0.023], arousal times [14.00(8.25, 8.00) vs 17.50(9.00,23.00),respectively, Z=19.68, P=0.041], microarousal ( Z=23.57, P=0.044), and AHI ( F=136.97, P=0.000) were increased in the OSAHS complicated with PFO group. Conclusions:OSAHS complicated with PFO patients had poor sleep quality and high incidence of sleep disorders. They had sleep disorder at night, which was characterized by the decrease of REM sleep and slow wave sleep, the prolongation of N2, the decrease of nocturnal SpO 2 and the increase of awakening times, and the increase of arousal times and AHI. PFO can aggravate the sleep disorder of OSAHS.

ABSTRACT

Objective:To explore the effect and mechanism of omega 3-polyunsaturated fatty acid(ω3-PUFA) dietary intervention on mitochondrial function of white adipose tissue in adult rats with postnatal early overfeeding.Methods:An overfed animal model by adjusting litter size was developed for the study of neonatal overfeeding. The litter size was adjusted to 3 male rats per litter(small litter, SL group) and 10 pups per litter(normal litter, NL group). After weaning(week 3), the pups were fed standard chow or ω3-PUFA diet(SL-FO) until postnatal weeks 13. Food intake, body weight, and rectal temperature of rats were measured regularly, and energy metabolism of animals was monitored in week 13. During week 3 and 13, subcutaneous adipose tissue was collected. Inguinal preadipocytes of mice were isolated and induced to differentiate, and 50 μmol/L eicosapentaenoicacid(EPA) was administered for 48 h at the late stage of differentiation. The mRNA and protein expression levels of mitochondrial related genes, mitochondrial copy number, and oxygen consumption rate of adipocytes were detected in adipose tissue and adipocytes.Results:By the 3rd week, the body weight, food intake, and fat cell area in SL group were higher than those in NL group while the body temperature was lower until to 13 weeks. By the 13th week, the O 2 consumption, CO 2 output, and heat production of rats in SL group were lower than those in NL group. Meanwhile, the expressions of mitochondrial function related genes such as uncoupling protein 1(UCP1), carnitine palmitoyltransferase 1(CPT1), SIRT1, and mitochondrial biosynthesis regulatory gene peroxisome proliferator-activated receptor coativator-1 (PGC1α) in adipose tissue by the 3rd and 13th week were significantly reduced( P<0.05). After weaning, ω3-PUFA diet significantly reduced weight gain in SL rats, increased UCP1 protein expression, restored energy metabolism level and mitochondrial function related gene expression. In vitro intervention of EPA increased the mitochondrial copy number, the mRNA and protein expression levels of mitochondrial biosynthesis and functional genes, as well as the mitochondrial basic oxygen consumption rate( P<0.05). Conclusion:ω3-PUFA improves postnatal overfeeding-induced impairment of the mitochondrial function and biosynthesis of subcutaneous white adipose tissue in rats, which may be an important mechanism for fish oil diet to inhibit the early over-nutrition program and restore the thermogenic metabolism.

ABSTRACT

Objective:To observe the effects of lifestyle intervention on diet, physical activities and health outcomes in obese children and adolescents during one year of follow up.Methods:A total of 153 obese children and adolescents with body mass index more than 95th percentage of the same age and sex were recruited consecutively from June 2015 to June 2017 in our hospital whose parents had signed the informed consent forms. The children were followed-up once every three months and their diet and physical activities, anthropometric measurement and metabolic indicators were assessed on research scheme, which lasted for one year.Results:A total of 52 obese children completed four visits plan in 12 months (34.0%, one year group), 101 children (66.0%) dropped from 3 to 9 months (66.0%, less than one year group). The intake of total energy [(8 524.5±2 068.6)kJ vs (6 464.0±1 586.9)kJ, P<0.05], dietary protein [(75.5±20.7)g vs (64.2±16.8)g, P<0.05], fat [(79.0±18.8)g vs (60.3±14.2)g, P<0.05], carbohydrates [(257.1±83.6)g vs (188.9±63.8)g, P<0.05] decreased after one year intervention in one year group. Moreover, the numbers of physical activity of medium to high intensity increased in obese children (0 vs 32.7%, P<0.05). BMI-SDS [(3.15±0.85) vs (2.46±0.81), P<0.05], WHtR [(0.60±0.04) vs (0.56±0.06), P<0.05] and FM% [(39.9±5.4) vs (33.0±7.4), P<0.05] were reduced, while SMM% [(32.1±3.2) vs (36.0±4.3), P<0.05] increased significantly in one year group. The detection rate of insulin resistance, dyslipidemia and nonalcoholic fatty liver disease (NAFLD) were reduced in one year group at the end of follow up ( P<0.05). The decrease of body fat and the increase of skeletal muscle were more obvious in one-year follow up group( P<0.05). Conclusion:Children and adolescent have less energy intake, more physical activities, good clinical outcomes and less complications of obesity through lifestyle intervention and follow up for one year, so it is worthy of being promoted.

ABSTRACT

Objective:To study the clinical characteristics of growth development and metabolic disorders in obese children and adolescents with insulin resistance (IR).Methods:Normal weight or obese children and adolescents who hospitalized at the Department of Children′s Health Care of Children′s Hospital Affiliated to Nanjing Medical University from September 2015 to April 2018 were recruited.Children′s height, body weight and waist circumference were measured, and waist-to-height ratio (WHtR) and body mass index (BMI) were calculated.Puberty process was determined by Tanner stage.Blood glucose, blood lipid and insulin were measured in fasting state, and homeostasis model assessment of insulin resistance (HOMA-IR) was calculated based on fasting blood glucose and insulin levels.IR was considered when HOMA-IR was over 2.69.Non-alcoholic fatty liver (NAFLD) was diagnosed by abdominal ultrasound.Results:(1) A total of 691 subjects were included, including 183 cases with the age of (9.73±2.38) years in the normal weight group/normal group, and 508 cases with the age of (10.24±2.05) years old in the obese group.The rate of IR was higher in obese group than that in normal group (55.71% vs. 10.38%), and the difference was statistically significant ( P<0.001). (2)HOMA-IR was positively correlated with age ( r=0.256, P<0.001), BMI ( r=0.426, P<0.001), waist circumference ( r=0.454, P<0.001), and WHtR ( r=0.321, P<0.001). After the adjustment for age, sex, and puberty stage, HOMA-IR was also positively correlated with BMI ( r=0.418, P<0.001), waist circumference ( r=0.419, P<0.001) and WHtR ( r=0.375, P<0.001). (3) During puberty, HOMA-IR in both of obese group and normal group was increased, and HOMA-IR in obese group was more particularly serious compared to normal group[TannerⅠ: 2.60(1.49, 3.94) vs.1.28(0.80, 1.90); Tanner Ⅱ: 3.07(1.75, 5.17) vs.1.80(1.16, 2.96); Tanner Ⅲ: 4.33(2.80, 6.57) vs.2.47(1.41, 3.68); Tanner Ⅳ-Ⅴ: 3.49(1.04, 5.78) vs.1.91(0.54, 2.60)], and the differences were all statistically significant(all P<0.05). (4)Compared with the obese objects without IR, obese children and adolescents with IR had higher systolic blood pressure[112(104, 124) mmHg vs.109(98, 121) mmHg, 1 mmHg=0.133 kPa], triglyceride level [1.27(0.95, 1.81) mmol/L vs.1.09(0.79, 1.61) mmol/L], fas-ting blood glucose level [4.80(4.46, 5.01) mmol/L vs.4.48(4.16, 4.76) mmol/L] and fasting insulin level [21.27(16.21, 28.56) mmol/L vs.7.62(4.43, 10.83) mmol/L], and the differences were all statistically significant(all P<0.05). IR was a risk factor for NAFLD in obese children( OR=1.536, 95% CI: 1.049-2.247, P<0.05). Conclusions:Serious and abdominal obesity in children and adolescents is a major risk factor for the development of IR.HOMA-IR of obese children and adolescents is particularly serious during puberty.The obese children with IR are more likely to have metabolic disorders in blood glucose, serum lipid and blood pressure, and have the risk of NAFLD development.

ABSTRACT

Objective To investigate the influencing factors for energy balance and the relationship be-tween energy balance and clinical outcome in PICU mechanical ventilation children. Methods Children with mechanical ventilation who were hospitalized in PICU for more than 3 days from June 2015 to May 2016 were collected, resting energy expenditure was measured by resting energy metabolic detector, and the nutrition bal-ance was calculated, the influencing factors on energy balance was analyzed by regression analysis. Results A total of 104 mechanical ventilation children were included with the average energy consumption of ( 265. 4 ± 63. 2) kJ/kg in the first 3 days and the average energy supply of (219. 8±82. 9) kJ/kg, and failed to reach the target value ( P<0. 05) . As the time of hospitalization was prolonged, the supply of energy increased gradu-ally, the SAPS Ⅱ ( r=-0. 609, P=0. 000) , mechanical ventilation time ( r=-0. 456, P=0. 000) , ICU stay time ( r=-0. 646, P=0. 000) , the number of organ failure ( r=-0. 568, P=0. 000) , infection complications ( r=-0. 859, P=0. 000) were negatively correlated to energy supply balance; regression analysis showed that complications of nosocomial infection ( P = 0. 000 ) , number of organ failure ( P = 0. 000 ) , mechanical ventilation time ( P=0. 000) , ICU retention time ( P=0. 001) were predictors of energy supply balance. Con-clusion Insufficient supply of energy for the first three days of mechanical ventilation is high in the critically ill children. Factors affecting energy supply balance include patient's organ failure, infection complications, me-chanical ventilation time, and ICU retention time, which suggest that the strengthening of the nutritional man-agement of the critically ill children with mechanical ventilation will benefit to the clinical outcome.

ABSTRACT

Objective To study the effects of painful procedures during neonatal period on rats' hippocampal gene expression in later life.Method A total of 28 newborn male rats were randomly assigned into two equal groups.From day1 (P1) to day7(P7) after birth,rats in the pain group received four times of needle acupuncture at the foot everyday,simulating the infants' experience in the NICU.Rats in control group were touched at the same side of the foot with a cotton swab.Transcriptome sequencing of the hippocampus of the two groups were examined on day 8 (P8) and day 21 (P21).The gene expression profiles were established and the differentially expressed genes were screened for functional analysis.Quantitative Real-time polymerase chain reaction (qRT-PCR) was used to confirm these differentially expressed genes (GABRB1,GRIN2A,IL1 RAPL1) related to pain-stimulated response or brain cognition,and one of the key genes was further verified using Western blotting.Result The sequencing results showed that there were only 6 differentially expressed genes in hippocampal tissues of rats on P8 in the two groups.Howerer,the number increased to 53 on P21 and 85.0% of these genes were down-regulated (45/53).Gene Ontology (GO) function enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis showed that the differentially expressed genes were mainly expressed on the cell membrane,voltage-gated ion channels,synapses,neurotransmitter receptors,immune responses,etc.The qRT-PCR and Western-blot results of key genes were consistent with the transcriptome sequencing.Conclusion Pain stimuli at an early stage after birth may trigger differentially expression of voltage-gated ion channel proteins,neurotransmitter receptors,and some key genes such as GABRB1 on hippocampal synaptic cell membranes in rats.These phenomenon may provide initial explanation for the molecular mechanism of early pain stimuli on neonatal brain development.

ABSTRACT

Breast milk is best nutrition source for infants. However,human breast feeding is ceased or changed as formula feeding during disease or disease treatment. Now,the important significance of breast feeding for infants with preterm,diarrhea,jaundice,allergy,genetic disease and congenital cleft palate are analyzed,and feeding program is pro-vided,which can help mothers continue breast feeding and let the infants get nutritional support and protection from breast feeding. By breast feeding,it may improve children rehabilitation growth and development.

ABSTRACT

Objective To study the characteristics of resting energy expenditure (REE) and evaluate the association between REE and obesity-related comorbidities in obese children and adolescents.Methods Recruited obese children and adolescents were recruited from the Department of Child Health Care in Nanjing Children's Hospital from July,2015 to September,2016.Height,weight(WT),waist circumference,hip circumference,blood pressure were measured.Puberty status was determined by Tanner staging.REE was measured by indirect calorimetry.Body composition,including fat mass (FM),fat free mass (FFM) were assessed in terms of bioelectrical impedance.Serum biochemical parameters were assessed,including fasting blood glucose (FBG),fasting blood insulin (FBI),total cholesterol (TC),triglyceride (TG),high-density lipoprotein cholesterol (HDL-C) and uric acid (UA).B-model ultrasonography of the liver was conducted.Results One hundred and ninety-six obese children (143 boys and 53 girls) aged 7-15 years were recruited.The measured REE was (1 497.2 ± 312.1) kcal/d.Pearson correlation analysis indicated that REE was positively related to age (r =0.386,P < 0.001),WT(r =0.676,P < 0.001),FM (r =0.629,P <0.001),FFM(r=0.635,P<0.001) and FM% (r =0.335,P<0.001),but negatively related to FFM% (r=-0.335,P <0.001).By studying stepwise linear regression,it was found that the factors which influenced REE were age and weight[REE(kcal/d) =899.469-32.098 × age (year) + 16.143 × weight (kg),P < 0.001].REE was expressed per kg of body weight (REE/WT),and there was a significant difference in REE/WT during pubertal development (P <0.001) in both males and females and the pubertal males had lower REE/WT than females.Moreover,REE/WT was lower in insulin resistant group compared to the normal insulin group.Meanwhile,REE/WT in hypertension group was lower than that in the normal blood pressure group.The above differences remained after adjusted for age adjustment(P <0.O1).Conclusion The decrease in REE/WT level in obese children and adolescents is correlated with puberty development and obesity complicated with insulin resistance and hypertension.

ABSTRACT

Sepsis is one of the most common diseases in the intensive care unit, which receives much concern because of its severe condition, high mortality rate and expensive medical costs. The definition and diagnostic criteria of sepsis are put forward in 1991 for the first time, and are widely accepted and used in clinical medicine. As the progress and development of critical care medicine and clinical pathophysiology, the definition and diagnostic criteria of sepsis are constantly updating, which is cause widely and heated discussion every time.

ABSTRACT

Objective:To investigate the effects of Zinc sulfate on preventing human umbilical veins endothelial cells ( HUVECs) from oxidative stress. Methods:Hydrogen peroxide was used to stimulate HUVECs to build the oxidative stress model in vitro. HUVECs were divided into normal group, H2 O2 group, Zinc sulfate group and Zinc sulfate treated group. Method of nitrate reductase was used to detect the content of nitric oxide ( NO ) and ELISA was used to detect the content of endothelin ( ET ) in supernatant in different groups. The level of HO-1,SOD and CAT of HUVECs were measured by Western blot. Apoptosis of HUVECs was examined by TUNEL as well. Results: Zinc sulfate could enhance the content of NO and decrease the content of ET in the supernatant,which induced by hydrogen peroxide on HUVECs. Zinc sulfate could also increase the level of HO-1, SOD and CAT obviously and decrease the apoptosis cells significantly induced by H2 O2 . Conclusion: Zinc sulfate play an important role in resisting oxidative stress in HUVECs, and maybe prevent HUVECs from oxidative stress damage. Zinc sulfate is expected to be an effective medicine on improving endothelial cells anti-oxidative ability.
