Growth and development of children and related influencing factors: a cross-sectional study of the families with children aged 0-6 years in Jiangsu Province / 中国当代儿科杂志

OBJECTIVES@#To investigate the growth and development of children aged 0-6 years in Jiangsu Province of China and the effects of family factors on the children's growth and development.@*METHODS@#The stratified random sampling method was used to select 2 004 families with children aged 0-6 years of Jiangsu Province. A questionnaire survey on nutritional knowledge, attitude, and behavior was performed for the main caregivers. The Z-score method was used to evaluate nutritional status. The ordinal polytomous logistic regression analysis model was used to investigate the influencing factors for nutritional status.@*RESULTS@#A total of 2 290 questionnaires were distributed, among which 2 004 valid questionnaires were collected (87.51%). The mean age of the children was (28±14) months, and there were 1 105 boys (55.14%) and 899 girls (44.86%). The primary caregivers were mostly parents (1 867 families, 93.16%), and the caregivers of 1 466 families (73.15%) had a university/college degree. Most families had an annual income of 50 000-100 000 yuan/year or 100 000-200 000 yuan/year, accounting for 32.88% and 34.23%, respectively. The results of Z-score showed the growth retardation rates of 1.45% (16/1 105) in boys and 1.78% (16/899) in girls, the underweight rates of 0.54% (6/1 105) in boys and 0.67% (6/899) in girls, the emaciation rates of 1.36% (15/1 105) in boys and 2.00% (18/899) in girls, and the obesity rates of 8.78% (97/1 105) in boys and 10.12% (91/899) in girls, respectively. The multivariate logistic regression analysis showed that a higher annual family income and a higher nutrition knowledge level of caregiver were beneficial to the growth and development of children (P<0.05).@*CONCLUSIONS@#Children aged 0-6 years in Jiangsu Province have a good status of growth and development but a relatively high obesity rate, and therefore, the monitoring of obesity should be taken seriously. Family economic status and the level of nutritional knowledge of caregivers have a significant impact on children's growth and development.

Real world thirty-day mortality in female patients with acute myocardial infarction from Beijing / 中华心血管病杂志

<p><b>OBJECTIVE</b>To evaluate the gender differences on the short-term outcomes of patients with acute myocardial infarction in the real world.</p><p><b>METHODS</b>A total of 471 consecutive patients [male 368(78.1%) and female 103(21.9%)] with acute myocardial infarction <72 hours in cardiac care unit were included. The clinical data, death and major adverse cardiac and cerebrovascular events at 30 days post hospitalization were analyzed.</p><p><b>RESULTS</b>Female patients were older (66.8 ± 10.1 vs. 56.9 ± 12.0, P < 0.001), TIMI score (5.1 ± 2.3 vs. 3.9 ± 2.1, P < 0.001) and GRACE score (162 ± 39 vs. 142 ± 35, P < 0.001) in female patients were higher than in male patients. Female patients had lower proportion of stent implantation (P = 0.038) while higher percentage of complex lesions and contraindications to PCI (P = 0.015) compared to male patients. Proportion of cardiac rupture, mitral regurgitation, malignant arrhythmia, post-infarction angina pectoris, contrast-induced nephropathy and minor gastrointestinal bleeding were also higher in female patients tan in male patients (P < 0.05). Thirty-day mortality was significantly higher in female patients than in male patients [5.8% (6/103) vs. 1.9% (7/368), P = 0.032], MACCE [10.7% (11/103) vs. 5.4% (20/368), P = 0.058] also tended to be higher in female patients than in male patients. Multi-logistic regression analysis showed that female gender was not an independent predictor for thirty-day mortality (P = 0.141) or MACCE (P = 0.426) while systolic blood pressure (OR = 1.072, 95%CI:1.016-1.130, P = 0.010) and pericardial effusion after myocardial infarction (OR = 40.518, 95%CI:1.098-1495.702, P = 0.044) were independent predictors for thirty-day mortality while systolic blood pressure (OR = 1.027, 95%CI:1.002-1.052, P = 0.036) and left ventricular ejection fraction (OR = 1.108, 95%CI:1.032-1.190, P = 0.005) were independent predictors for MACCE.</p><p><b>CONCLUSIONS</b>Female gender itself is not an independent predictor for thirty-day mortality and MACCE despite poorer clinical characteristics, higher incidence of complications, and worse prognosis in female patients.</p>

Short-term prognosis and risk factors of ventricular septal rupture following acute myocardial infarction / 中华心血管病杂志

<p><b>OBJECTIVE</b>To analyze the short-term prognosis and risk factors of ventricular septal rupture (VSR) following acute myocardial infarction (AMI).</p><p><b>METHODS</b>A total of 70 consecutive VSR patients following AMI hospitalized in our hospital from January 2002 to October 2010 were enrolled in this study. We compared the clinical characteristics of patients with VSR who survived ≤ 30 days (n = 39) and survived > 30 days (n = 31) post AMI. A short-term prognosis index of VSR (SPIV) was established based on the logistic regression analysis.</p><p><b>RESULTS</b>The single factor analysis showed that the risk factors of death within 30 days of VSR patients were female, anterior AMI, Killip class 3 or 4, apical VSR and non-aneurysm (all P < 0.05). Logistic regression analysis revealed that female (P = 0.013), anterior AMI (P = 0.023), non-aneurysm (P = 0.023), non-diabetes (P = 0.009), Killip class 3 or 4 (P = 0.022) and time from AMI to VSR less than 4 days (P = 0.027) were independent risk determinants for death within 30 days post VSR. Patients with SPIV ≥ 9 were associated with high risk [77.4% (24/31)] of dying within 30 days post AMI. SPIV ≤ 8 were associated with low risk as the 30 days mortality is 28.6% (8/28).</p><p><b>CONCLUSION</b>Female gender, anterior AMI, non-aneurysm, non-diabetes, Killip class 3 or 4 and time from AMI to VSR less than 4 days are independent risk factors of short-term mortality of VSR.</p>

Clinical analysis and risk stratification of ventricular septal rupture following acute myocardial infarction / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Ventricular septal rupture (VSR) remains an infrequent but devastating complication of acute myocardial infarction (AMI). The best time to undergo surgical repair is controversial and there is currently no risk stratification for patients with VSR to guide treatment. The purpose of this study was to review the clinical outcomes of 70 patients with VSR, to analyze the short-term prognosis factors of VSR following AMI, and to make a risk stratification for patients with VSR.</p><p><b>METHODS</b>A total of 70 consecutive VSR patients following AMI treated in our hospital from January 2002 to October 2010 were enrolled in this study retrospectively. The difference of clinical characteristics were observed between patients with VSR who survived ≤30 days and survived >30 days. We analyzed the short-term prognosis factors of VSR and established the short-term prognosis index of VSR (SPIV) based on the Logistic regression analysis to stratify patients with VSR.</p><p><b>RESULTS</b>Among 12 354 patients with acute ST-segment elevation myocardial infarction, 70 (0.57%) patients (33 males and 37 females) were found to have VSR. The average age was (68.1±8.5) years. Fifty-four (77.1%) patients were diagnosed with an acute anterior infarction. Patients with VSR selected for surgical repair had better outcomes than patients treated conservatively; 1-year mortality 9.5% versus 87.8%, P < 0.005. Logistic regression analysis revealed that female (P = 0.013), anterior AMI (P = 0.023), non-ventricular aneurysm (P = 0.023), non-diabetes (P = 0.009), Killip class 3 or 4 (P = 0.022) and time from AMI to VSR less than 4 days (P = 0.027) were independent risk determinants for shortterm mortality. SPIV ≥9 indicates a high risk as the 30-day mortality is 77.4%; SPIV <8 indicates a low risk as the 30-day mortality is 28.6%; SPIV between 8 and 9 indicates a moderate risk.</p><p><b>CONCLUSIONS</b>VSR remains a rare but devastating complication of AMI. The independent risk determinants for short-term mortality of VSR were female gender, anterior AMI, non-ventricular aneurysm, non-diabetes, Killip class 3 or 4, and the time from AMI to VSR less than 4 days. It is reasonable to take more active treatments for the patients at high risk to save more lives.</p>

The cSNPs analysis in whole extron-wide of PGC-1alpha gene in Chinese population and the domain MEF2C bioinformatics study / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To analyze distribution characteristics of PGC-1alpha gene coding single nucleotide polymorphisms (cSNPs), and to investigate the association between cSNPs and type 2 diabetes mellitus, and to study biological information about PGC-1alpha domain muscle enhancer factor 2C (MEF2C) in Chinese Han population.</p><p><b>METHODS</b>These cSNPs were identified by means of polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP), polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and DNA direct sequencing technology in a total of 263 type 2 diabetic patients and 282 normal glucose tolerant controls. The possible association was analyzed between type 2 diabetes mellitus and the specific cSNPs and their haplotypes by case-control method. The tertiary structure of PGC-1alpha domain MEF2C was predicated and analyzed for possible biological information by a series of bioinformatics soft wares.</p><p><b>RESULTS</b>Four variants were found in whole extron-wide of PGC-1alpha gene in Chinese Han diabetic population. They were 394G/A, 482G/A, 528A/G and 612C/T. The 482G/A polymorphism was remarkably associated with type 2 diabetes (chi2 = 14.2025, P= 0.0002). Haplotypes analysis shown that distribution frequency of haplotypes had a statistical difference between type 2 diabetes mellitus and normal glucose tolerance control groups (chi2 = 59.9, P< 0.01) and haplotype 394A-482A-528A had a linkage disequilibrium with type 2 diabetes (t= 2.361, P< 0.05). The tertiary simulant structure of PGC-1alpha domain MEF2C was established successfully by computer. The 482G/A variant accompanied with hydrogen bonds breaking might decrease hydrophobicity and lead to an incompact space configuration which was very critical to function.</p><p><b>CONCLUSION</b>The 482G/A variant could decrease binding force between PGC-1alpha and MEF2C and increase the risk of type 2 diabetes in Chinese Han population by PGC-1alpha -MEF2C-GLUT-4 pathway.</p>

Changes of the proportion and mortality of pulmonary thromboembolism in hospitalized patients from 1974 to 2005 / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Pulmonary thromboembolism (PTE) has become a common disease that severely endangers people's health. This study analysed the changes in proportion and mortality of PTE in hospitalized patients to provide data for prevention and management of the disease.</p><p><b>METHODS</b>The data of 763 hospitalized patients with PTE from 1974 to 2005 in Fuwai Hospital were analysed.</p><p><b>RESULTS</b>During the 1970s, 0.27% of patients in a cardiovascular hospital had PTE (< 5 cases per year); while so far this century the proportion is 0.94% (48 to 113 per year). The mortality of hospitalized PTE patients fell from 20.00% in the 1970s to 4.10% this century. Prior to 1990, the mortality of hospitalized PTE patients was 12.50%, and in the years after 1990 only 3.40%. The difference was statistically significant (P < 0.005). People with this disease were mostly between the ages of 30 and 69 years. Men were most susceptible between the ages of 30 and 69 years, while women between the ages of 40 and 69 years. Men contracted PTE 10 years earlier than women. The mortality of male PTE patients was 4.70%, not significantly different from female patients, 5.06% (0.50 < P < 0.75). There were not any significant differences between the mortality of patients in the different age groups overall (< or = 39, 40 - 49, 50 - 59, and > or = 60 years, P > 0.1). More people contracted the disease in winter than in other seasons (P < 0.05). There was no obvious difference between the mortality in different seasons overall (0.75 < P < 0.90).</p><p><b>CONCLUSION</b>PTE is an increasingly significant disease and deserves adequate attention.</p>
