ABSTRACT

OBJECTIVE@#To analyze effect of accordion technique on bone mineralization of extended bone segment in treating tibial bone defect with bone transport.@*METHODS@#From May 2017 to October 2019, 22 patients with tibial bone defects were treated with Ilizarov bone-transport technique, and divided into two groups after bone-transport was completed, 11 patients in each group. In observation group, there were 9 males and 2 females aged from 20 to 60 years old with an average of (42.6± 13.3) years old;the length of bone defect ranged from 3 to 13 cm with an average of(6.4±2.6) cm;2 patients were suffered from upper tibial bone defects, 3 patients were middle and 6 patients were lower;patients were treated with accordion technique for 35 days. In control group, there were 10 males and 1 female aged from 41 to 60 years old with an average of (51.6±6.4) years old;the length of bone defect ranged from 3 to 10.7 cm with an average of (6.6±2.5) cm;1 patient was suffered from upper tibial bone defects, 3 patients were middle and 7 patients were lower;patients were treated with lock external fixator to waiting bone mineralization. The content of hydroxyapatite (HAP) extended bone segment was measured after bone-transport completed immediately, 35, 65 and 95 days after bone-transport was completed, respectively, then the mineralization time and healing time were compared between two groups, and the therapeutic effect of bone defect was evaluated by using Paley scoring criteria.@*RESULTS@#Twenty-two patients were followed up from 18 to 36 months with an average of (27.0±6.3) months. The wounds on the bone defects healed spontaneously during bone transport, and there were no wound complications such as skin infection or skin necrosis occurred. There were statisticaldifference in the content of HAP of the extended bone segments at 35, 65 and 95 days after bone-transport between two groups (@*CONCLUSION@#Accordion technique and locking external fixator mineralization in prolonging bone segment healing after bone-transport have the equal clinical effect, while the accordion technique could significantly accelerate the growth rate of HAP and shorten the mineralization time and healing time.

ABSTRACT

BACKGROUND@#With current chemotherapy treatment, >90% of survival has been obtained for Burkitt lymphoma (BL). In this study, the demographic characteristics and treatment outcomes are presented for 78 children in China with central nervous system-positive (CNS+) BL.@*METHODS@#This retrospective study consecutively enrolled 78 CNS+ BL patients in Beijing Children's Hospital (BCH) from 2007 to 2019 who received the BCH B-cell non-Hodgkin's lymphoma regimen (modified by French-American-British mature lymphoma B-cell 96 [FAB/LMB96] C1 arm ± rituximab). Clinical characteristics, methods of disease detection in the CNS, and outcomes were evaluated. Univariate and multivariate analyses were used to assess prognostic factors.@*RESULTS@#The median age of 65 boys and 13 girls at the time of diagnosis was 5.7 years (ranging from 1 to 14 years). Patients were followed up for a median time of 34 months (ranging from 1 to 72 months). Bone marrow invasion was found in 38 (48.7%) patients. There were 48 (61.5%), 44 (56.4%), and 25 (32%) patients with cranial nerve palsy, intracerebral mass (ICM), and para-meningeal extension, respectively. Abnormal cerebrospinal fluid (CSF) morphology and CSF immunophenotype appeared in 15 (19.2%) and 15 (19.2%) patients, respectively. There were 69 (88.5%) patients treated with chemotherapy combined with rituximab, and nine patients were treated solely with chemotherapy. Finally, five patients died of treatment-related infection, recurrence occurred for 13, and one developed a second tumor. The 3-year overall survival and event-free survival rates were 78.9% ± 4.7% and 71.4% ± 6.0%, respectively. Treatment with chemotherapy only, ICM positivity, and >4 organs involved at diagnosis were independent risk factors.@*CONCLUSIONS@#Rituximab combined with a modified LMB96 regimen has greatly increased the efficacy of treatment for Chinese children with CNS+ BL, and with the continuous collection of outcome data, treatment-related complications are decreasing. For further verification, a large sample multicentre randomized controlled study should be performed to explore a treatment scheme for Chinese children with even greater efficacy.

ABSTRACT

OBJECTIVE@#We aimed to evaluate the combined effects of a high body shape index (ABSI) and a high serum C-reactive protein (CRP) level on the incidence of ischemic stroke in a Mongolian population in China.@*METHODS@#A prospective cohort study was conducted among 2,589 participants from June 2002 to July 2012 in Inner Mongolia, China. The participants were categorized into 4 groups according to their level of ABSI and CRP. Cox proportional hazards models were used to assess the hazard ratios (HRs) and 95% confidence intervals (CIs) for ischemic stroke among all groups.@*RESULTS@#The multivariate adjusted HRs (95% CI) of ischemic stroke for high ABSI and high CRP level were 1.46 (0.89-2.39) and 1.63 (0.95-2.79), respectively. Compared with the low ABSI/low CRP level group, the multivariate adjusted HRs (95% CI) of ischemic stroke in the low ABSI/high CRP, high ABSI/low CRP, and high ABSI/high CRP groups were 1.04 (0.46-2.35), 1.06 (0.58-1.95) and 2.52 (1.27-5.00), respectively. The HR of ischemic stroke for the high ABSI/high CRP level group was the highest and most statistically significant.@*CONCLUSION@#We found that participants with simultaneously high ABSI and high CRP levels had the highest risk of ischemic stroke in the Mongolian population. Our findings suggest that the combination of high ABSI and high CRP levels may increase the risk of ischemic stroke.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effect of early rehabilitation intervention on the incidences of extrauterine growth retardation (EUGR) and early diseases in preterm infants.</p><p><b>METHODS</b>The appropriate-for-gestational-age preterm infants with a gestational age of <34 weeks and a birth weight of 1 000 to <2 000 g who were admitted to the neonatal intensive care unit (NICU) within 24 hours after birth were enrolled in a prospective randomized controlled trial. These infants were randomly divided into rehabilitation intervention group and control group. The infants in the rehabilitation intervention group were given early rehabilitation after their vital signs became stable, including oral sensory and muscle strength training and pressure touching of the head, chest, abdomen, extremities, hands, and feet. The primary outcome measures were the time to independent oral feeding, length of hospital stay, and incidence rate of EUGR. The secondary outcome measures were the incidence rates of related diseases in preterm infants, such as apnea, feeding intolerance, and sepsis.</p><p><b>RESULTS</b>A total of 97 preterm infants who met the inclusion criteria and had complete data were enrolled, with 48 in the control group and 49 in the rehabilitation intervention group. The rehabilitation intervention group had a shorter time to independent oral feeding than the control group (P<0.05). Compared with the control group, the rehabilitation intervention group had a shorter length of hospital stay and a lower corrected gestational age at discharge (P<0.05), as well as a lower incidence rate of EUGR (P<0.05). The rehabilitation intervention group ONCLUSIONS: Early rehabilitation intervention for preterm infants in the NICU may reduce the incidence rates of apnea, feeding intolerance, and EUGR and help them to achieve independent oral feeding early.</p>

ABSTRACT

The objective of this study was to evaluate the usefulness of the China-PAR equations in predicting the 10-year risk of cardiovascular disease (CVD) in the Inner Mongolians population. A population-based, prospective cohort of 2,589 Mongolians were followed up from 2003 to 2012. Participants were categorized into 4 subgroups according to their 10-year CVD risks calculated using the China-PAR equations: < 5%, 5%-9.9%, 10%-19.9%, and ⪖ 20%. The China-PAR equations discriminated well with good C statistics (range, 0.76-0.86). The adjusted hazard ratios for CVD showed an increasing trend among the 4 subgroups (P for trend < 0.01). However, the China-PAR equations underestimated the 10-year CVD risk in Mongolians, and the calibration was unsatisfactory (Hosmer-Lemeshow χ2 = 19.98, P < 0.01 for men, χ2 = 46.58, P < 0.001 for women). The performance of the China-PAR equations warrants further validation in other ethnic groups in China.

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the effect of clustering of cardiovascular risk factors (CVRFs) on type 2 diabetes mellitus (T2DM) incidence and identify some high predictive clusters in the Inner Mongolian population in China.</p><p><b>METHODS</b>A total of 1,884 Mongolian individuals aged 20 years or above were followed up from 2002 to 2013 and included in the final analysis. We categorized the participants into two subgroups according to the study outcome event. A Cox proportional hazards model was used to evaluate the effect of clustering of CVRFs on the incidence of T2DM. Areas under the curve were used to compare the effect of every cluster on T2DM and identify those having higher predictive value.</p><p><b>RESULTS</b>We found 203 persons with T2DM. Subjects with incident T2DM tended to be older, had a higher prevalence of drinking, had higher systolic and diastolic pressures; total cholesterol, triglyceride, low-density lipoprotein cholesterol, and C-reactive protein levels; waist circumference; body mass index; and heart rate and lower HDL-C level than did those without T2DM. The multivariable adjusted hazard ratio (95% confidence interval) of T2DM was calculated based on comparisons with subjects with 0 CVRFs; in participants with 2 and ⪖ 3 factors, the adjusted hazard ratios were 2.257 (1.448, 3.518) and 3.316 (2.119, 5.188), respectively.</p><p><b>CONCLUSION</b>The clustering of CVRFs increased the risk of T2DM. On the basis of fast heart rate, the cluster of abdominal obesity and other CVRFs had higher predictive value for T2DM than the other three CVRF clusters.</p>

ABSTRACT

This prospective study was designed to examine the combined influence of insulin resistance (IR) and inflammatory biomarker levels on type 2 diabetes mellitus (T2DM) among 1,903 Inner Mongolians. During follow-up, 205 (10.77%) participants developed T2DM, and the incidence of T2DM was higher among subjects with IR, elevated C-reactive protein (CRP), elevated sICAM-1, elevated sE-selectin, or the coexistences of IR with elevated CRP, elevated sICAM-1, elevated sE-selectin, and elevated angiotensin II (all P < 0.05) compared with patients without IR or any elevated biomarkers. In multivariate analysis, the odd ratios [OR, (95% confidence intervals)] for these conditions were 1.944 (1.405-2.691), 2.003 (1.449-2.767), 1.706 (1.232-2.362), 1.560 (1.123-2.165), 2.708 (1.809-4.054), 1.885 (1.155-3.078), 2.101 (1.340-3.295), and 2.260 (1.426-3.582), respectively. Our findings demonstrated that IR and elevated inflammatory biomarkers were associated with T2DM, and that the coexistence of IR and elevated inflammatory biomarkers increased the risk of T2DM.

ABSTRACT

BACKGROUND: Preliminary experiments have confirmed that poly(hydroxybutyrate-co-hydroxyoctanoate) (PHBHOx)/collagen composite osteochondral scaffold exhibits desirable pore structure and biocompatibility. OBJECTIVE: To investigate the effect of PHBHOx/collagen composite osteochondral scaffold carrying bone marrow mesenchymal stem cells in the repair of articular osteochondral defects in the weight-bearing area of rabbits. METHODS: Cone-shaped osteochondral defects were created in the femoral medial condyle of the right knee of 30 New Zealand white rabbits. Then, the rabbit models were randomized into three groups and underwent implantation of PHBHOx/collagen composite osteochondral scaffold carrying bone marrow mesenchymal stem cells in the scaffold-cell group, PHBHOx/collagen composite osteochondral scaffold in the scaffold group and no intervention in the control group. At 4 and 12 weeks after surgery, animals were sacrificed for gross, Micro-CT, histological and immunohistochemical collagen II observations. RESULTS AND CONCLUSION: At 12 weeks after surgery, Micro-CT scanning results suggested that osteochondral defects were not repaired in the control group, repaired incompletely in the scaffold group with many new bone trabeculae, and repaired completely in the scaffold-cell group. Histological results showed that at 4 weeks after surgery, the defects in the control group were filled with amorphous tissues, subchondral bone formation just occurred in the scaffold group but increased in the scaffold-cell group. At 12 weeks after surgery, trabecular bone structure with no cartilage lacuna was observed in the control group; incomplete subchondral bone formation was observed in the scaffold group, and the cartilage layer was repaired by the fibrous tissues; in the scaffold-cell group, osteochondral defect repair was complete, with the emergence of tidal line, and the newborn cartilage was completely integrated with the surrounding normal tissue in addition to a similar thickness. At 12 weeks after surgery, collagen II basically did not express in the control group, weakly expressed in the scaffold group and highly expressed in the scaffold-cell group. In short, the PHBHOx/collagen composite osteochondral scaffold promotes the repair of articular osteochondral defects in the weight-bearing area.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the tumor inhibition effect of Yangfei Kongliu Formula (YKF), a compound Chinese herbal medicine, combined with cisplatin (DDP) and its action mechanisms.</p><p><b>METHODS</b>C57BL/6 mice with Lewis lung carcinoma were divided into six groups: control group (C), DDP group (2 mg/kg, DDP), low-dose YKF group (2.43 g/kg, L), high-dose YKF group (24.3 g/kg, H), low-dose YKF combined with DDP group (L + DDP) and high-dose YKF combined with DDP group (H + DDP). Transforming growth factor-β1 (TGF-β1), mothers against decapentaplegic homolog 3 (Smad3) and Smad7 levels were measured with quantitative real-time polymerase chain reaction (qPCR), Western blotting and immunohistochemistry. An enzyme-linked immunosorbent assay was used to analyze the expressions of interleukin-2 (IL-2) and tumor necrosis factor-α (TNF-α).</p><p><b>RESULTS</b>YKF combined with DDP significantly inhibited the growth and metastasis of tumors relative to the control group, and YKF groups (P < 0.05). There was no significant difference between high-dose YKF group and low-dose YKF group (P > 0.05). We also found that the expression levels of TGF-β1 and Smad3 were both significantly decreased by YKF relative to the control group (P < 0.05). Furthermore, after treatment with YKF combined with DDP, the expression levels of TGF-β1 and Smad3 were decreased but the expression level of Smad7 was increased relative to the DDP group (P < 0.05). Compared to the DDP group, the combination of YKF and DDP enhanced the effect of tumor inhibition (P < 0.05), showing obvious synergy between YKF and DDP. Treatment with DDP or YKF decreased serum levels of IL-2 and TNF-α relative to the control group (P < 0.05). Furthermore, the expression levels of IL-2 and TNF-α were significantly decreased when treated with YKF in combination with DDP. Co-treatment with YKF and DDP significantly inhibited tumor growth, decreased the expressions of TGF-β1, Smad3, IL-2 and TNF-α and increased the expression of Smad7; these differences were significant relative to both YKF groups and the control group (P < 0.05).</p><p><b>CONCLUSION</b>YKF can inhibit tumor growth synergistically with DDP, mainly through the TGF-β1 signaling pathway.</p>

ABSTRACT

Background & Objective: Radiotherapy and temozolomide are the standard therapy for newly diagnosed glioblastoma multiforme (GBM). However, it is unclear whether adding another agent to the commonly used radiotherapy-temozolomide (RT + TMZ) benefits newly diagnosed GBM patients. The present network meta-analysis aimed to assess the efficacy of combining other agents with RT + TMZ for GBM treatment. Methods: A comprehensive literature search was conducted on PubMed, EMBASE.com, Web of Science, and the Cochrane Central Register of Controlled Trials from inception to September 23, 2014, to include all randomized controlled trials of RT + TMZ-based therapy in GBM patients. Pairwise and network meta-analyses were performed to compare the therapeutic regimens. Results: Seventeen studies involving 4,148 patients were identified. The results of pairwise meta-analysis indicated no significant differences among most comparison groups, except for bevacizumab + RT + TMZ versus RT + TMZ for progression-free survival (hazard ratio [HR] = 0.71, 95% confidence interval [CI]: 0.59–0.86; P = 0.000) and RT + TMZ versus RT alone for overall survival (HR = 0.71, 95% CI: 0.58–0.88; P = 0.001). The results of network meta-analysis also showed no significant differences in most comparisons; however, adverse events were more common among patients receiving additional therapeutic agents other than RT + TMZ. The ranking probability analysis indicated that bevacizumab + RT + TMZ and nimustine + cisplatin + RT + TMZ were associated with the best progression-free and overall survival, but they also caused the most adverse events in GBM patients. RT + bevacizumab + irinotecan had the highest probability of being the best regimen for minimizing adverse events. Conclusions: The addition of other targeted agents, particularly bevacizumab and nimustine, to RT + TMZ could be slightly effective for the treatment of newly diagnosed GBM patients; however, adverse events remained common.

ABSTRACT

<p><b>OBJECTIVE</b>We aimed to evaluate the combined effect of a family history of cardiovascular disease (CVD) and high serum C-reactive protein (CRP) on the stroke incidence in an Inner Mongolian population in China.</p><p><b>METHODS</b>A prospective cohort study was conducted from June 2002 to July 2012, with 2,544 participants aged 20 years and over from Inner Mongolia, China. We categorized participants into four groups based on the family history of CVD and CRP levels.</p><p><b>RESULTS</b>We adjusted for age; sex; smoking; drinking; hypertension; body mass index; waist circumference; and blood glucose, triglycerides, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol levels. Compared with the group with no family history of CVD/low CRP levels, the group with family history of CVD/high CRP levels had a hazard ratio (HR) of 1.78 [95% confidence interval (CI), 1.03-3.07; P = 0.039] of stroke, and an HR of 2.14 (95% CI, 1.09-4.20; P = 0.027) of ischemic stroke. The HRs of hemorrhagic stroke for the other three groups were not statistically significant (all P > 0.05).</p><p><b>CONCLUSION</b>Participants with both a family history of CVD and high CRP levels had the highest stroke incidence, suggesting that high CRP levels may increase stroke risk, especially of ischemic stroke, among individuals with a family history of CVD.</p>

ABSTRACT

<p><b>OBJECTIVE</b>We aimed to investigate the cumulative effect of high CRP level and apolipoprotein B-to-apolipoprotein A-1 (ApoB/ApoA-1) ratio on the incidence of ischemic stroke (IS) or coronary heart disease (CHD) in a Mongolian population in China.</p><p><b>METHODS</b>From June 2003 to July 2012, 2589 Mongolian participants were followed up for IS and CHD events based on baseline investigation. All the participants were divided into four subgroups according to C-reactive protein (CRP) level and ApoB/ApoA-1 ratio. Cox proportional hazard models were used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs) for the IS and CHD events in all the subgroups.</p><p><b>RESULTS</b>The HRs (95% CI) for IS and CHD were 1.33 (0.84-2.12), 1.14 (0.69-1.88), and 1.91 (1.17-3.11) in the 'low CRP level with high ApoB/ApoA-1', 'high CRP level with low ApoB/ApoA-1', and 'high CRP level with high ApoB/ApoA-1' subgroups, respectively, in comparison with the 'low CRP level with low ApoB/ApoA-1' subgroup. The risks of IS and CHD events was highest in the 'high CRP level with high ApoB/ApoA-1' subgroup, with statistical significance.</p><p><b>CONCLUSION</b>High CRP level with high ApoB/ApoA-1 ratio was associated with the highest risks of IS and CHD in the Mongolian population. This study suggests that the combination of high CRP and ApoB/ApoA-1 ratio may improve the assessment of future risk of developing IS and CHD in the general population.</p>

ABSTRACT

<p><b>OBJECTIVE</b>No previous studies have evaluated the association between dyslipidemia, alcohol drinking, and diabetes in an Inner Mongolian population. We aimed to evaluate the co-effects of drinking and dyslipidemia on diabetes incidence in this population.</p><p><b>METHODS</b>The present study was based on 1880 participants from a population-based prospective cohort study among Inner Mongolians living in China. Participants were classified into four subgroups according to their drinking status and dyslipidemia. Multivariate logistic regression analysis and receiver operating characteristic (ROC) curves were used to evaluate the association between alcohol drinking, dyslipidemia, and diabetes.</p><p><b>RESULTS</b>During the follow-up period, 203 participants were found to have developed diabetes. The multivariable-adjusted odds ratios (95% confidence interval) for the incidence of non-dyslipidemia/drinkers, dyslipidemia/non-drinkers, and dyslipidemia/drinkers in diabetic patients were 1.40 (0.82-2.37), 1.73 (1.17-2.55), and 2.31 (1.38-3.87), respectively, when compared with non-dyslipidemia/non-drinkers. The area under the ROC curve for a model containing dyslipidemia and drinking status along with conventional factors (AUC=0.746) was significantly (P=0.003) larger than the one containing only conventional factors (AUC=0.711).</p><p><b>CONCLUSION</b>The present study showed that dyslipidemia was an independent risk factor for diabetes, and that drinkers with dyslipidemia had the highest risk of diabetes in the Mongolian population. These findings suggest that dyslipidemia and drinking status may be valuable in predicting diabetes incidence.</p>

ABSTRACT

A new triterpenoid ester, 7β-hydroxyl-hop-22(29)-en-3β-O-palmitate (1), was isolated from the stems and leaves of Scurrula parasitica parasitic on Nerium indicum, along with nine known compounds, uvaol (2), 3-epi-ursolic acid (3), 3β-hydroxyl-hop-22(29)-ene (4), 3β, 15α-dihydroxyl-lup-20(29)-ene (5), lup-20(29)-en-3-O-α-D-glucoside (6), stigmasterol-3-O-β-D-glucoside (7), digitoxin-3-O-α-D-glucoside (8), behenic acid (9), octacosyl alcohol (10). Their structures were elucidated using a combination of 1D and 2D NMR techniques (COSY, HMQC, and HMBC) and HR-ESI-MS analyses. Compounds 2-10 were isolated from this plant for the first time.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the incidence, clinical features, and treatment of perinatal cytomegalovirus (CMV) infection, as well as the factors affecting the therapeutic effect of ganciclovir.</p><p><b>METHODS</b>The clinical data of 237 infants who were hospitalized and diagnosed with perinatal CMV infection from 2008 to 2012 were retrospectively analyzed.</p><p><b>RESULTS</b>The clinical features of infants with perinatal CMV infection and the proportion of such infants in all hospitalized infants showed no significant differences across the five years. In most infants, two or more systems were involved, and CMV hepatitis plus CMV pneumonia was most common (43.1%). The results of pathogen detection showed that the percentage of the infants with positive blood CMV-IgM and blood/urine CMV-DNA was 3.8%, while 90.3% of all infants had positive blood CMV-IgM alone and 5.9% had positive blood/urine CMV-DNA alone. A total of 197 infants were treated with ganciclovir, and the cure rate was 88.3%. An abnormal history of pregnancy (OR=6.191, 95% CI: 1.597-24.002) and liver involvement before medication (OR=3.705, 95% CI: 1.537-8.931) were the independent risk factors affecting the therapeutic effect of ganciclovir in infants with perinatal CMV infection.</p><p><b>CONCLUSIONS</b>The epidemiological characteristics of perinatal CMV infection have remained generally stable for the last 5 years. CMV often involves several organs or systems, especially the liver and lung. Ganciclovir has a significant efficacy in the treatment of perinatal CMV infection, and an abnormal history of pregnancy and liver involvement before medication can increase the risk of ganciclovir resistance in infants with perinatal CMV infection.</p>

ABSTRACT

<p><b>OBJECTIVE</b>Waist circumference, waist-to-hip ratio and waist-to-height ratio, which are the indicators or measures of abdominal adiposity, have long been hypothesized to increase the risk of stroke; yet evidence accumulated till date is not conclusive. Here, we conducted a dose-response meta-analysis to summarize evidences of the association between these measures of abdominal adiposity and the risk of stroke.</p><p><b>METHODS</b>PubMed and Web of Science databases were searched from inception to May 2015. Two investigators independently conducted the study selection and data extraction. Dose-response relationships were assessed by the generalized least squares trend estimation, while the summary effect estimates were evaluated by the use of fixed- or random-effect models. Subgroup and sensitivity analyses were performed to assess the potential sources of heterogeneity and the robustness of the pooled estimation. Publication bias of the literature was evaluated using Begg's and Egger's test.</p><p><b>RESULTS</b>Altogether 15 prospective cohort studies were identified in this study. The summary of relative risks (95% confidence intervals) of stroke for the highest versus the lowest categories was 1.28 (1.18-1.40) for waist circumference, 1.32 (1.21-1.44) for waist-to-hip ratio, and 1.49 (1.24-1.78) for waist-to-height ratio. For a 10-cm increase in waist circumference, the relative risk of stroke increased by 10%; for a 0.1-unit increase in waist-to-hip ratio, the relative risk increased by 16%; and for a 0.05-unit increase in waist-to-height ratio, the relative risk increased by 13%. There was evidence of a nonlinear association between waist-to-hip ratio and stroke risk, Pnonlinearity=0.028.</p><p><b>CONCLUSION</b>Findings from our meta-analysis indicated that waist circumference, waist-to-hip ratio, and waist-to-height ratio were positively associated with the risk of stroke, particularly ischemic stroke.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the correlated factors contributed to extrauterine growth restriction (EUGR) in preterm infants with the gestational age less than 34 weeks.</p><p><b>METHODS</b>A total of 694 preterm infants with the gestational ages less than 34 weeks were enrolled. They were classified into EUGR and non-EUGR groups by weight on discharge. The perinatal data, growth data, nutritional information and morbidities during hospitalization were compared between the two groups.</p><p><b>RESULTS</b>EUGR on discharge occurred in 284 (40.9%) out of the 694 infants. The incidence of EUGR in intrauterine growth restriction (IUGR) infants was significantly higher than in non-IUGR infants (P<0.01). The very low birth weight (VLBW) infants had a higher incidence of EUGR than non-VLBW infants (P<0.01). The incidence of EUGR increased with the decreases of gestational age at birth and birth weight (P<0.01). Compared with the non-EUGR group, the fasting time, the duration of parenteral nutrition, the time beginning to feed and the age to achieve full enteral feeds were significantly greater in the EUGR group (P<0.01). The cumulative protein deficit and cumulative caloric deficit in the first week of life in the EUGR group were higher than in the non-EUGR group (P<0.05). The incidences of respiratory distress syndrome, apnea, necrotizing enterocolitis and septicemia in the EUGR group were higher than in the non-EUGR group (P<0.05). The logistic regression analysis showed that birth weight, gestational age at birth and IUGR were the independent risk factors for EUGR.</p><p><b>CONCLUSIONS</b>The incidence of EUGR in infants with gestational age less than 34 weeks is high, especially in IUGR or VLBW infants. Early and aggressive nutritional strategy and prevention of apnea and septicemia may facilitate to reduce the occurrence of EUGR.</p>
