ABSTRACT
Objective@#To investigate the recurrence of pulmonary tuberculosis patients 5 years after successful treatment in Hengyang City, Hunan Province, and to analyze its influencing factors.@*Methods@#The data of pulmonary tuberculosis patients who were successfully treated in Hengyang City in 2014 were collected through the tuberculosis management information system. The recurrence of pulmonary tuberculosis was defined as the endpoint, and all patients were observed for five consecutive years. Factors affecting recurrence of pulmonary tuberculosis were identified using Kaplan-Meier estimates, log-rank test and multivariable Cox proportional hazards regression analysis.@*Results@#A total of 6 626 patients with successfully treated pulmonary tuberculosis were included, including 4 961 males and 1 665 females, with a median age of 54 years. There were 536 cases with recurrence of pulmonary tuberculosis within five years, with a 8.09% cumulative proportion of recurrence and annual recurrence rate of 1.75 per 100 person-years. Multivariable Cox proportional hazards regression analysis showed that men ( HR=1.592, 95%CI: 1.256-2.019 ), age of 40 years and greater ( age of 40 to 59 years, HR=7.025, 95%CI: 1.739-28.377; age of 60 years and greater, HR=8.175, 95%CI: 2.024-33.023), farmers ( HR=1.379, 95%CI: 1.070-1.778 ), retreatment ( HR=6.398, 95%CI: 5.163-7.929 ) and positive etiology ( HR=1.255, 95%CI: 1.042-1.511 ) were risk factors for five-year recurrence of pulmonary tuberculosis among successfully-treated patients.@*Conclusions@#High recurrence rate is found among pulmonary tuberculosis patients within five years after successful treatment in Hengyang City. There is a high risk of pulmonary tuberculosis recurrence among male, etiologically positive, retreated farmers at ages of 40 years and older, and targeted interventions are recommended.
ABSTRACT
Aortic dissection is an acute injury of the aortic intima due to various factors from the outside or itself. The rapid blood flow enters the middle layer of the aortic elastic force from the breach and expands longitudinally along the aorta to form a true and a false two lumens. Aortic dissection is a rare, high-risk cardiovascular disease with a low incidence, but it is extremely harmful. Lesions can affect the systemic system, without treatment, the natural prognosis is poor. Surgery is the most effective treatment, especially for Stanford A and high-risk Stanford B dissection. With the increase of the incidence of aortic dissection, the diagnosis and treatment and nursing technology have developed rapidly in recent years, but the mortality rate is still high due to the complex, rapid changes and complications. This article reviews the current status of preoperative aortic dissection in order to improve the understanding of clinical nurses and provide a reference for the perioperative nursing intervention study of aortic dissection.
ABSTRACT
Objective To investigate the effects and mechanism of (-)-epigallocatechin-3-gallate (EGCG) on white adipose tissue angiogenesis in high fat diet rats.Methods Twenty-four male weaning SD rats were randomly divided into normal control group,high fat diet group and EGCG intervention group,8 rats in each group.Normal control group were fed with normal diet,high-fat diet group were fed with high-fat diet,EGCG intervention group were fed with high-fat diet along with intragastric administration of 200 mg/ (kg · d) EGCG.After 8 weeks,the rats were sacrificed.The adipocyte size and vascular density of the abdominal adipose tissue in rats in each group were observed under the microscope.The serum vascular endothelial growth factor (VEGF) concentration was detected by Elisa Kit.RT-PCR was used to detect the expression of VEGF,nuclear factor E2 (Nrf2),heme oxygenase-1 (HO-1),catalase (CAT),SOD,GPx,interleukin-6 (IL-6) and monocyte chemoattractant protein-1 (MCP-1) mRNA.Results The adipocyte size,number of vascular/each adipocyte,serum VEGF concentration and VEGF mRNA expression in adipose tissue of high fat diet group were significantly higher than those of normal control group (all P＜0.05).EGCG can significantly reduce the above indicators of high fat diet group (all P＜0.05).The expression of Nrf2,HO-1,SOD,GPx and CAT mRNA in adipose tissue of EGCG group was significantly higher than those in high fat diet group and normal control group (all P＜0.05).The expression of MCP-1 and IL-6 mRNA in adipose tissue of EGCG group was significantly lower than that in high fat diet group (all P＜0.05).Conclusion EGCG can decrease the production of serum VEGF,vascular density and the expression of VEGF mRNA in white adipose tissue of high fat diet rats,and inhibit the angiogenesis in white adipose tissue possibly due to its up-regulation of Nrf2/HO-1 pathway to increase the expression of antioxidant enzymes (SOD,CAT,GPx),reduce ROS production and decrease the inflammatory response.
ABSTRACT
Objective To analyze the epidemic characteristics of multidrug-resistant tuberculosis(MDR-TB)in Hunan Province from 2013 to 2016,and provide theoretical basis for the prevention and control of tuberculosis.Methods Information about TB patients in Hunan Province reported by China Information System for Disease Control and Prevention between January 2013 and December 2016 was analyzed retrospectively.Results From 2013 to 2016,the total drug resistance registration rate in Hunan Province was 5.53/million(1 496/270 330 000),multidrug registration rate was 5.40/million(1 459/270 330 000),drug resistance rate and multidrug resistance rate showed an upward trends(trend x2 =113.605,96.590,respectively,both P<0.001).Among MDR-TB patients,male were more than females(74.09%vs 25.91%),most were more than 25 years of age,especially 45～age group(27.07%);the proportion of patients with MDR-TB retreatment was higher than that of the initial treatment(69.91%vs 30.09%).From 2013 to 2016,distribution range of MDR registration rates in different regions were 4.07/million-7.23/million.Conclusion MDR-TB in Hunan Province in 2013-2016 is increasing year by year,and mainly concentrate on young people over 20 years old.There are more cases of male and retreatment;it is necessary to strengthen regular treatment and prevention of key population,enhance the ability to identify and diagnose MDR-TB patients,and reduce the spread of MDR-TB.
ABSTRACT
Objective To evaluate the impact of total parenteral nutrition(TPN)on nutrition status and inflammatory markers in hospitalized fasted patients with inflammatory bowel disease(IBD).Methods A retrospective study was performed and 82 hospitalized fasted IBD patients [male/female=58/24,(39.4±14.5)years] who received TPN entered the study.Among them,38 patients had ulcerative colitis(UC)and 44 patients suffered from Crohn`s disease(CD).Clinical data(gender,age,duration of disease,history of disease,prednisone,immuno-suppressor,and antibiotics)were obtained from medical records.Nutritional parameters,C-creative protein(CRP),and erythrocyte sedimentation rate(ESR)before and after TPN were also obtained.Average caloric supplementation by TPN was(4 437.3±1 199.1)kJ/d and the nitrogen amount was(9.9±1.7)g/d.Median PN length was 15 days(7-54 days).67 IBD patients received a TPN formula with glutamine(≥14 d,25 patients vs.0-14 d,42 patients)and 15 IBD subjects received TPN without glutamine.Malnutrition was diagnosed by body mass index(BMI)and serum albumin level.Results The prevalence of undernutrition was 90.2％(74/82)in the study population.CD patients had a significantly longer history of disease [84(3-288)months vs.24(1-324)months,P<0.001] and a significantly lower BMI [(15.6±1.8)kg/m2 vs.(19.1±3.5)kg/m2,P<0.001] compared with those in UC patients.TPN improved nutritional parameters [serum albumin:(28.7±6.6)g/L before TPN vs.(31.7±5.8)g/L after TPN,P<0.001;pre-albumin:(174.1±85.5)mg/L before TPN vs.(227.2±82.8)mg/L after TPN,P<0.001].Conclusions TPN improves nutritional status in hospitalized fasted IBD patients.However,prospective randomized controlled trials are required to estimate the role of low-to-middle dosage of glutamine in IBD patients.
ABSTRACT
Objective To evaluate the effects of assisted reproduction technology ( ART) on gestational weight gain ( GWG) and glucose metabolism .Methods The study was performed in ART women with single-ton and full-term delivery .Age-and pre-pregnancy body mass index matched healthy women with spontaneous pregnancy, singleton, and full-term delivery were recruited as controls .Maternal characteristics (height, age, education level , pre-pregnancy body mass , pre-delivery body mass , medical history , history of abortion , fasting plasma glucose , triglyceride , total cholesterol , and glucose tolerance ) and fetal data ( delivery mode , gender , birth body mass , birth body length ) were collected by a trained nutritionist .Results A total of 200 women were recruited into this study (53 ART women and 147 controls).There was no significant difference in number of previous abortion ( the ratio between the women who had ≥3 abortions to those who had <3 abortions was 6∶47 in the ART group , and 10∶137 in the control group , χ2 =1.080 , P=0.299 ) .Compared with the control group, the ART group had higher education level (33 in the ART and 85 in the control group with un-dergraduate or higher education , 20 in the ART group and 62 in the control group with a college degree or lower education ,χ2 =6.303 , P=0.012 ) .There were no statistically significantly differences between the ART and the control groups in pre-pregnancy body mass index [ (22.00 ±3.05 ) kg/m2 vs.(21.81 ±2.62 ) kg/m2 , P=0.661] and average GWG [ (13.89 ±5.33) kg vs.(14.78 ±4.60) kg, P=0.247].GWG was appro-priate in 22 ART women, excess in 18, and inadequate in 13;in the control group, GWG was appropriate in 66 women, excess in 54, and inadequate in 27.The distribution of GWG showed no significant difference be-tween the two groups (χ2 =1.162 , P=0.247 ) .Oral glucose tolerance test in 24-28 gestational weeks showed no significant difference in fasting blood glucose between the ART and the control groups [ (4.66 ±0.39) mmol/L vs.(4.66 ±0.52) mmol/L, P=0.996], but 1-hour and 2-hour blood glucose levels were significantly in-creased in the ART women [ ( 7.87 ±1.83 ) mmol/L vs.( 7.31 ±1.51 ) mmol/L, P=0.034; ( 7.49 ± 1.29) mmol/L vs.(6.69 ±1.30) mmol/L, P=0.029].The overall prevalence of gestational diabetes melli-tus was 13.5%(27/200), with no significant difference between the ART and the control groups (18.9%vs. 11.6%, P=0.182 ) .Conclusion ART may not affect GWG , but it may cause changes of glucose metabo-lism during pregnancy .
ABSTRACT
Objective To investigate the relationship between serum ferritin and nonalcoholic fatty liver diseases in obese children.Methods Obese children aged 6 to 14 years old were enrolled.Duration of obesity, anthropometric parameters (height, body weight, waist circumference, hip circumference), bioelectrical impedance analysis (body fat), serological parameters (liver transaminases, lipid metabolism, fasting blood glucose, fasting insulin, serum ferritin) and liver ultrasonography were recorded.Insulin resistance (IR) index was calculated by homeostasis model assessment (HOMA).All subjects were divided into 3 groups according to liver ultrasound and liver transaminases : simple obese children (SOC) group, obese children with nonalcoholic simple fatty liver (NAFL) group and obese children with nonalcoholic steatohepatitis (NASH) group.Results 86 obese children entered the study, with a mean age of (10.4 ± 1.9) years, including 26 in the SOC group, 28 in the NAFL group and 32 in the NASH group.Waist circumference standard deviation score (SDS or Z-score), waist-to-hip ratio, HOMA-IR index and serum ferritin in the NASH group were obviously higher than those in the NAFL group [2.3 ± 0.3 vs.2.1 ± 0.3, P =0.020;1.0 ± 0.0 vs.0.9 ± 0.1,P=0.014;4.0±1.7 vs.2.9±1.8, P=0.006;(104.1 ±49.6) μg/Lvs.(68.4 ±22.7) μg/L, P=0.004] and the SOC group [2.3 ±0.3 vs.1.9 ±0.3, P=0.000;1.0±0.0vs.0.9 ±0.1, P=0.012;4.0 ±1.7 vs.2.5 ±1.6, P=0.001;(104.1 ±49.6) μg/Lvs.(59.2 ±28.9) μg/L, P=0.001], while there was no significant difference in body mass index Z-score [2.8 ± 0.5 vs.2.7 ± 0.6, P =0.524;2.8 ± 0.5 vs.2.7 ± 0.6, P =0.662].There were no significant differences between the NAFL group and the SOC group in the above indicators [2.1 ±0.3 vs.1.9 ±0.3, P =0.260;0.9 ±0.1 vs.0.9 ±0.1, P =0.952;2.9 ± 1.8vs.2.5±1.6, P=0.283;(68.4±22.7) μg/Lvs.(59.2±28.9) μg/L, P=0.161].Mter controlling age, body mass index, waist circumference, waist-to-hip ratio, triglyceride, and HOMA-IR index, serum ferritin was still positively correlated with the magnitude of nonalcoholic fatty liver diseases in obese children (r =0.335, P =0.002).Conclusion Serum ferritin is probably an independent risk factor for NASH in obese children.
ABSTRACT
Objective To evaluate the relationship between birth weight and nonalcoholic fatty liver diseases (NAFLD) in Chinese primary school students. Methods A cross-section study was conducted in ifve elementary schools in Gao Hang Town, Shanghai and 2163 students were enrolled in the study (1120 boys/1043 girls). Height, body weight, waist circumference and per-cent of body fat (bioelectrical impedance analysis) were measured by professional nutritionist after training. Birth weight, feeding pattern, height and body weight of parents were obtained by a self-completed questionnaire. NAFLD was diagnosed by ultra-sound. The risk factors of NAFLD were analyzed. Results The prevalence of NAFLD in the study population was 8.9%. The prevalence of NAFLD was signiifcantly higher in boys than that in girls (12.5%vs 5.0%, P<0.01). Logistic regression showed that sex (OR=1.97, 95%CI:1.21-3.21) and percent of body fat (OR=1.12, 95%CI:1.07-1.17) were the risk factors of NAFLD, and normal BMI was the protective factor of NAFLD (OR=0.09, 95%CI:0.04-0.19) in the study population. Conclusions The pre-valence of NAFLD is higher in boys than that in girls. Also overweight, and high percent of body fat are risk factors of NAFLD in children.
ABSTRACT
Objective To investigate the infection status quo of 21 kinds of genotypes of human papillomavirus (HPV)and their distribution rule among the women in Hengyang region.Methods A total of 8 032 women voluntarily accepting cervical cancer screening in the Hengyang Municipal Maternal and Child Health Care Hospital fromg April 2012 to May 2013 were selected as the research subjects.The exfoliated cells samples of cervical tissue were collected for detecting 21 kinds of HPV genotypes by Hybri-Max.The HPV infectious rate and the HPV gene distribution were analyzed by using SSPS13.0.Results Of 8 032 women,1 664 cases were detected out 1 kind or more than 2 kinds of HPV,the HPV infectious rate was 20.72%(1 664/8 032).The top 6 geno-types of HPV were HPV16,52,58,81,53 and 18.Among 1 664 female cases of HPV infection,the single HPV infection rate was 76.44%,the multiple infection rate was 23.56%,which was dominated by the double infection;the total positive rate in the various age groups of HPV infection presented theU-type distribution with the age increase,however the total positive rate had no statis-tically significant differences among all age groups(P >0.05 ).Conclusion The HPV female infection rate in Hengyang region is relatively higher,moreover the high risk HPV is predominant.HPV 16 occupies the top ranking.
ABSTRACT
Objective To investigate the risk factors of central venous catheters (CVC) colonization.Methods A retrospective study was performed on adult patients with CVCs placement in Renji Hospital,Shanghai Jiaotong University from January 2006 to March 2010.Clinical data,catheter-related information (including duration of catheter placement,position and purpose of catheterization,and whether or not out-of-ward catheterization),catheter culture results,and prevalence of catheter-related blood stream infection (CRBSI)was collected.Results A total of 651 patients aged 18 to 97 years (median:63 years) were enrolled in the study,in whom 762 CVC were placed.The median duration of catheter placement was 1 1 days (2 to 122 days)and the total duration of CVC placement was 10 725 days.The prevalence of catheter colonization was 16％(122/762),and 134 germs were cultured.Gram-positive cocci was the most common colonized bactera (52.2％,70/122),followed by gram-negative bacilli (33.6％,45/122) and fungi (14.2％,19/122).Overall 13 CRBSI were confirmed and the rate of CRBSI was 1.21/1000 catheter-days.Logistic regression analysis demonstrated that the risk factors for CVC colonization included mechanical ventilation [odds ratio (OR) =1.783,95％ confidence interval (Cl) =1.108 ～2.870],serum albumin concentration less than 25 g/L before catheterization (OR =1.783,95％ Cl =1.357 ～ 6.757),prolonged duration of catheter placement (OR =1.105,95％ Cl =1.009 ～ 1.111),and out-of-ward catheterization (OR =2.837,95％ Cl =1.010 ～7.969).Conclusion Patients with prolonged duration of catheter placement and out-of-ward catheterization are inclined to CVC colonization.
ABSTRACT
Objectives To investigate the prevalence of non-alcoholic fatty liver (NAFLD) disease and its correlation with chronic metabolic diseases in two primary school students in Shanghai. Methods One thousand ifve hundred and thirty-two 7-11 year-old students from two primary schools were enrolled in Septamber-October 2011. The anthropometric indices, blood pressure, screening for pseudoacanthosis nigricans and liver ultrasonography of all subjects were recorded. Results The overall prevalence of NAFLD, obesity, abdominal obesity, pseudoacanthosis nigricans, high systolic blood pressure and high diastolic blood pressure was 6.5%, 26.7%, 16.3%, 5.1%, 1.7%and 1.9%, respectively. The prevalence of NAFLD and abdomi-nal obesity in students of central urban area was signiifcantly higher than that in suburban area (P<0.01). The binary regression analysis revealed a signiifcant association between NAFLD in students with sex, age, obesity, abdominal obesity, pseudoacan-thosis nigricans and high systolic blood pressure (P<0.05). Conclusions NAFLD has close correlation with chronic metabolic disease in children. It is time to adopt prevention, detection and treatment in NAFLD children with symptoms of chronic meta-bolic diseases.

ABSTRACT
ObjectiveTo determine the subcellular localization of exogenous human papillomavirus type 16 E6 protein(HPV16 E6) and hDaxx in HeLa cells and their effects on tumor necrosis factor (TNF)-α-induced apoptosis.MethodsHeLa cells were transfected with plasmids pDsRed-monomer-C1/HPV16 E6,pEGFP-CI/hDaxx,pEGFP-C1 and pDsRed-monomer-C1 respectively.Subsequently,Western blot was carried out to quantify the expression of fusion proteins DsRed-HPV16E6 and EGFP-hDaxx in transfected cells,and laser scanning confocal microscopy to observe the subcellular distribution of HPV16 E6 protein and hDaxx.Some HeLa cells were divided into 5 groups:untransfected (control group),untransfected and treated with TNF-α(TNF-ot group),transfected with pcDNA3.1 (-) and treated with TNF-α(empty vector group),transfected with pcDNA3.1 (-)/HPV16 E6 and treated with TNF-α (HPV16 E6 group),cotransfected with pcDNA3.1(-)/HPV16 E6 and pcDNA3.1 (-)/hDaxx and treated with TNF-α (cotransfected group).After additional culture,the cells were collected and subjected to flow cytometry(FCM) to evaluate the apoptosis of cells as well as spectrophotometry to determine the relative activity of Caspase-8 and Caspase-3.ResultsWestern blot showed that both DsRed-HPV16 E6 and EGFP-hDaxx were expressed in HeLa cells.In Hela cells transfected with pDsRedmonomer-C1/HPV16 E6 or pEGFP-C1/hDaxx alone,the red fluorescence of HPV16 E6 was observed in the nucleus and cytoplasm,while the green fluorescence of hDaxx only in the nucleus; in those cotransfected with pDsRed-monomer-C1/HPVl6 E6,HPV16 E6 and hDaxx proteins were regionally aggregated near the nuclear membrane in nuclei,and hDaxx was partly translocated from the nucleus to the cytoplasm.The apoptosis rate and relative activity of Caspase-8 and Caspase-3 were statistically lower in HPV16 E6 group than in the empty vector group and cotransfected group(21.4％ ± 1.1％ vs.27.0％ ± 0.9％ and 32.5％ ± 2.1％,0.057 ± 0.003 vs.0.092 ±0.012 and 0.109 ± 0.013,0.054 ± 0.006 vs.0.093 ± 0.005 and 0.110 ± 0.004,all p＜ 0.01).Conclusions HPV16 E6 protein induces the partial translocation of hDaxx from the nucleus into the cytoplasm and colocalizes with hDaxx in the cells.The apoptosis of HeLa cells induced by TNF-α can be suppressed by HPV16 E6 protein,while the overexpression of hDaxx can attenuate the suppressing effect of HPV16 E6 protein on apoptosis in Hela cells.
ABSTRACT
Objective To evaluate the effects of lipid emulsion on parenteral nutrition associated liver dis ease (PNALD) in old tumor patients. Methods A retrospective study was performed with 402 patients in Renji Hospital from January 2003 to December 2008. Patients were retrieved according to the following criteria: (1)age ≥60 years; (2) confirmed diagnosis of tumor, had no evidence of metastasis, and tumor was completely resected before receiving parenteral nutrition; (3) liver and kidney function was in normal range before receiving parenteral nutrition; (4) parenteral nutrition days ≥7; and (5) parenteral nutrition was infused in "all in one" bag via central venous. Patients with history of viral hepatitis or died in parenteral nutrition episode were excluded. These 402 patients aged (71.7 ±6.8) years and the average parenteral nutrition time was (10. 2 ±5.9) (range, 7-61 )days. In 311 patients (77.4％), non-protein calorie was obtained from carbohydrate and lipid and 91 patients (22. 6％ ) just obtained non-protein calorie from carbohydrate. Results The total prevalence of PNALD was 15.2％ (61/402). The prevalence of PNALD was 8.8％ (8/91) in patients receiving parenteral regiment without lipid and 17.0％ (53/311) in patients receiving parenteral nutrition with lipid, and there was no significant difference in prevalence of PNALD between two groups (χ2 = 3.72, P = 0.07 ). Lipid type and amount showed no significant effects on PNALD ( P ＞ 0.05 ). The fever days ( P ＜ 0. 001 ), baseline level of alanine transaminase (P ＜0. 001 ) and γ-glutamyltransferase (P ＜0. 001 ) were risk factors for liver injury by logistic regression. Conclusion Lipid emulsion can be safely used in old tumor patients without affecting the occurrence of PNALD.
ABSTRACT
Objective To investigate the distribution of homeostasis model assessment-insulin resistance(HOMA-IR)index and its relationship with metabolic syndrome and inflammatory cytokines in students aged 7 to 14 years. Methods The data of 366 students(n=163 for boys and n=203 for girls) aged 7 to 14 years were collected,including anthropometric parameters (height,body weight,body mass index,waist circumference,hip circumference and waist-hip ratio),blood pressure,total fat mass,fat proportion,fasting blood lipid,fasting blood glucose,fasting insulin and serum levels of inflammatory cytokines such as tumor necrosis factor-α(TNF-α),C-reactive protein(CRP)and interleukin-6(IL-6),and insulin resistance was evaluated by HOMA-IR index. Results The 75 th percentile of HOMA-IR index for boys and girls was 3.62 and 2.88,respectively.Body weight,height,body mass index,waist circumference,hip circumference,total fat mass and fat proportion were positively related to HOMA-IR index(P<0.01).When HOMA-IR index surpassed 75th percentile,age,anthropometric parameters,total fat mass,fat proportion and systolic blood pressure significantly increased in boy and girl students(P<0.05),no significant change occurred in diastolic blood pressure in boy and girl students,the levels of serum TNF-α and IL-6 significantly increased in boy students(P<0.05),while there was no significant change in level of CRP in boy students and levels of CRP.TNF-α and IL-6 in girl students. Conclusion The increase of HOMA-IR index leads to a dramatic increase of anthropometrie parameters,total fat mass,fat proportion and serum TNF-α and IL-6 in boy students,while that results in the increase of anthropometric parameters,total fat mass and fat proportion in sid students,with no significant change in serum inflammatory cytokines.
ABSTRACT
Objective To investigate the prevalence of parenteral nutrition related central venous catheter infection in elder patients with malignant tumors,and explore the risk factors. Methods The clinical data of 366 patients with malignant tumors who were managed with parenteral nutrition after operation were retrospectively analysed.The data of age,gender, body weight,diagnosis of primary disease,surgical approach,past history,volume of blood and albumin transfusion and time of fever(body temperature ≥38℃) were collected.Parenteral nutrition related parameters such as time of parenteral nutrition,total calorie,non-protein cMorie,amount of fat,protein and glucose,calorie to nitrogen ratio and carbohydrate to fat ratio were also recorded. Results The mean age of 366 patients was (71.8±6.9)years,mean time of parenteralnutrition was (10.6±6.3)d,and total time of catheterization was 3 336 days.The prevalence of parenteral nutrition related central venous catheter infection was 2.5%(9/366).Logistic regression analysis demonstrated that the relative risks of plasma albumin level before parenteral nutrition and time of high fever to catheter infection were 1.257 and 2.518,respectively(P<0.01 for both). Conclusion Plasma albumin level before parenteral nutrition and time of fever were two risk factors for parenteral nutrition related catheter infection in elder patients with malignant tumors.
ABSTRACT
Objective To investigate the incidence of metabolic syndrome among obese children in clinics. Methods One hundred and thirteen obese children aged 7 to 14 years were selected from clinics of nutrition(case group),and another 366 healthy students aged 7 to 14 years were served as controls.Height,body weight,waist circumference,hip circumference,blood pressure and liver ultrasound were measured,related biochemical parameters such as fasting blood glucose,fasting insulin,serum total cholesterol,triglyceride(TG),hiSh density lipoprotein and low density lipoprotein were detected,and the incidences of metabolic syndrome were obtained in two groups.Insulin resistance(IR)was evaluated by homeostasis model assessment(HOMA). Results There was no significant difference in age and gender between case group and control group(P>0.05).Body weight,body mass index(BMI),waist circumference,hip circumference,waist to hip ratio,systolic blood pressure,diastolic blood pressure,fasting blood glucose,fasting insulin,HOMA index and TG in case group were significantly higher than those in control group(P<0.01).The 75th percentile of HOMA index in control group was 3.28,and IR subgroup and non-IR subgroup were divided according to this cutpoint.In case group,body weight,BMI,waist circumference and TG in non-IR subgroup were significantly higher than those in IR subgroup (P< 0.05).Metabolic syndrome occurred in 51 cases(45.1%) in case group.The incidence of metabolic syndrome was higher in IR subgroup than that in non-IR group(50.0% vs 21.1%)(P<0.05). Conclusion The prevalence of metabolic syndrome is higher in overweight and obese children.IR has a close relationship with metabolic syndrome.
ABSTRACT
ObjectiveTo observe the influence of different dietary protein intake (DPI) on nitrogen balance and nutritional indices in peritoneal dialysis (PD) patients, and explore the minimal DPI to maintain nitrogen balance.MethodsThirty-four PD patients were randomly divided into group A, B and C with DPI as 1.2, 0.9 and 0.6 g·kg-1·d-1 respectively. All the patients admitted into our hospital and completed a 10-day assessment for nitrogen balance, as well as nutritional status including serum albumin (Alb), pre-albumin at baseline, the 7th and 10th day. ResultsThe DPI of group A, B and C was (1.18±0.05), (0.87±0.02), (0.66±0.03) g·kg-1·d-1, whose differences were significant (P<0.01). The dietary energy intake (DEI) was 129.29 (117.57-133.89), 111.71 (100.42-133.47), 146.86 (128.03-163.18) kJ·kg-1·d-1 respectively. Nitrogen balance was positive in group A, B, C [2.99 (2.15-4.72) g, 1.20(0.59-1.89) g, 0.24 (-0.87-1.27) g]. The BUN decreased at the 7th and 10th day (P<0.01) in group C. The BUN and phosphorus in group A increased, but without significant difference as compared to baseline. No significant differences of nutritional status were found among three groups throughout the trial. ConclusionMinimal DPI 0.65 g·kg-1·d-1 plus the supplement of protein loss in dialysate can maintain the nitrogen balance in peritoneal dialysis patients.
ABSTRACT
Objective To explore the prevalence of parenteral nutrition-associated liver disease (PNALD) and its risk factors in elderly people after gastrointestinal operation. Methods Seventy-five patients received parenteral nutrition (PN) after gastrointestinal operation were retrospectively analyzed. Age, height, body mass index, suftering diseases, history of diseases, time of therapy, total calorie, nonprotein calorie, the kind and amount of fat emulsion and amino acid, the amount of glucose, non-protein energy to nitrogen ratio, ratio of glucose to lipid, liver function, renal function and blood routine were collected. Results The prevalence of PNALD was 25.3% (19/75). The total calorie, nonprotein calorie, the amount of protein, the amount of glucose and ratio of glucose to lipid were obviously higher in PNALD group than in non-PNALD group [(24.0±6.5) vs. (20.7±5.4)kcal·kg-1·d-1, (20.5±5.5)vs. (17.2±4.8)kcal·kg-1·d-1, (1.0±0.3)vs. (0.9±0.2)g ·kg-1·d-1, (2.9±0.9)vs.(2.3±0.9)g·kg-1·d-1, 1.5±0.7 vs. 1.1±0.5; all P<0.05], while the hemoglobin was lower in PNALD group [(97.4±15.1)vs. (110.1±19.1)g/L, P<0.05]. The kind of fat emulsion and amino acid, gender, history of diseases, suftering diseases, body mass index, serum albumin, leukocyte levels and renal function were comparable between the two groups (χ2=0.114,0.843,0.116,0.531,0.344,1.588,0.006,0.063 and 0.549, all P>0.05). Conclusions The prevalence of PNALD is 25.3% in 75 elderly patients after gastrointestinal operation. Total calorie, the amount of glucose and the ratio of glucose to lipid should be reduced in these patients for preventing PNALD.
ABSTRACT
Daxx is found in the nucleus where it localizes to PML oncogenic domains (PODs). Its multiple domains can interact proteins involved in transcriptional regulation and apoptotic signal transduction. In addition, Daxx is associated with viral infection、tumorigenesis and embryonic development.
