ABSTRACT
Objective To investigate the prevalence and risk factors of hyperuricemia in physical examination group of Zhangjiakou, and to provide evidence for the prevention of hyperuricemia. Methods The physical examination people in the Number One Hospital of Zhangjiakou were selected as the research objects from May 2016 to May 2017 . Their physique indexes such as height, weight and blood pressure were tested, and their blood sample were collected and biochemical indexes such as fasting plasma glucose (FPG), blood uric acid (UA), triglyceride (TG) and total cholesterol (TC) were detected. Logistic regression model were used to analyze the influencing factors of hyperuricemia. Results A total of 17273 examinees were recruited, with the average age of (47.42±14.28) years. There were 10324 men (59.77％) and 6949 women (40.23％) . The prevalence rate of hyperuricemia was 22.14％. The prevalence rate of hyperuricemia in men was 28.39％, higher than that of women (12.87％) (P<0.001) . Logistic regression analysis showed that obesity/overweight (OR=2.206, 95％ CI: 1.986-2.450), high TG (OR=2.089, 95％CI: 1.903-2.293) and high TC (OR=1.121, 95％CI: 1.006-1.249) were risk factors of the male patients with hyperuricemia, while the elderly (OR=0.982, 95％CI: 0.979-0.985) and high FPG (OR=0.657, 95％ CI: 0.587-0.736) were protective factors. The risk factors of the female patients with hyperuricemia were the elderly (OR=1.008, 95％CI: 1.001-1.014), obesity/overweight (OR=2.193, 95％CI: 1.864-2.579), high FPG (OR=1.379, 95％CI: 1.128-1.687) and high TG (OR=2.209, 95％ CI: 1.879-2.597) . Conclusion The prevalence of hyperuricemia among residents in Zhangjiakou of Hebeiis high. Overweight / obesity and high TG are the risk factors for hyperuricemia.
ABSTRACT
Objective To study the changes of serum brain natriuretic peptide(BNP),uric acid(UA)and procalcitonin(PCT)levels in children patients with dilated cardiomyopathy(DCM).Methods 24 children pa-tients with DCM and 24 children undergoing healthy physical examination from March 2015 to September 2016 were selected as the observation group and control group.The observation group was divided into differ-ent Ross grade groups according to the improved Ross heart failure grade scoring.The levels of serum BNP, UA and PCT in each group were detected and their correlation with the main echocardiographic indicators was analyzed.Results The levels of BNP,UA and PCT had statistical difference between the observation group and control group(P<0.05);the BNP and UA levels had statistical difference among different Ross grades (P<0.05),moreover which were increased along with the severity increase,but the PCT level had no statisti-cally significant(P> 0.05);the BNP level was positively correlated with the DCM severity(r= 0.713,P=0.000),the UA level was positively correlated with the DCM severity(r=0.489,P=0.002),while the corre-lation between the PCT level and DCM severity had no statistical significance(r=0.288,P=0.076);the BNP had obvious correlation with main echocardiographic indicators(P<0.05).Conclusion The levels of serum BNP,UA and PCT in children patients with DCM are changed significantly,in which BNP and UA may be the good markers for reflecting the disease severity and progression or prognosis.
ABSTRACT
Objective To explore the effect of intermedin ( IMD ) and adrenomedullin ( ADM ) on cerebral microcirculation in rats with cerebral ischemia. Methods Rat cerebral ischemia ( CI) model was established by middle cerebral artery occlusion. 40 SPF male adult Sprague-Dawley ( SD) rats were randomly divided into three groups:CI+NS ( normal saline) group, CI+ADM group and CI+IMD group, which were used to observe the changes of brain surface microcirculatory perfusion with a laser Doppler flowmeter. Results The differences of brain surface microcirculatory perfusion were statistically significant among the CI+NS group, CI+ADM group and CI+IMD group ( F=53. 426, P<0. 05 ) . Multiple comparison showed that the brain surface microcirculatory perfusion in the CI+IMD group was higher than that of the CI+NS group and CI+ADM group. Conclusions Intermedin can improve the cerebral microcirculation in rats with cerebral ischemia, and its therapeutic effect is better than adrenomedullin.
ABSTRACT
<p><b>BACKGROUND</b>Differentiating intracerebral hemorrhage (ICH) from cerebral infarction as early as possible is vital for the timely initiation of different treatments. This study developed an applicable model for the ambulance system to differentiate stroke subtypes.</p><p><b>METHODS</b>From 26,163 patients initially screened over 4 years, this study comprised 1989 consecutive patients with potential first-ever acute stroke with sudden onset of the focal neurological deficit, conscious or not, and given ambulance transport for admission to two county hospitals in Yutian County of Hebei Province. All the patients underwent cranial computed tomography (CT) or magnetic resonance imaging to confirm the final diagnosis based on stroke criteria. Correlation with stroke subtype clinical features was calculated and Bayes' discriminant model was applied to discriminate stroke subtypes.</p><p><b>RESULTS</b>Among the 1989 patients, 797, 689, 109, and 394 received diagnoses of cerebral infarction, ICH, subarachnoid hemorrhage, and other forms of nonstroke, respectively. A history of atrial fibrillation, vomiting, and diabetes mellitus were associated with cerebral infarction, while vomiting, systolic blood pressure ≥180 mmHg, and age <65 years were more typical of ICH. For noncomatose stroke patients, Bayes' discriminant model for stroke subtype yielded a combination of multiple items that provided 72.3% agreement in the test model and 79.3% in the validation model; for comatose patients, corresponding agreement rates were 75.4% and 73.5%.</p><p><b>CONCLUSIONS</b>The model herein presented, with multiple parameters, can predict stroke subtypes with acceptable sensitivity and specificity before CT scanning, either in alert or comatose patients. This may facilitate prehospital management for patients with stroke.</p>

<p><b>BACKGROUND</b>Chronic kidney disease (CKD) is a growing public health problem with well-established risk factors. Other contributing factors, however, remain to be identified. Systemic inflammation in asthma plays a significant role in the development of other diseases. We therefore initiated a study to assess whether the growing prevalence of asthma is associated with an increase in the risk of CKD.</p><p><b>METHODS</b>We conducted a retrospective cohort study using data from 3015 patients with asthma aged 14 years and older who were registered and followed up in Asthma Control Study at the Department of Respiratory Medicine of three medical centers from 2005 to 2011. History, asthma control test (ACT), and asthma stage were used to assess the traits of asthma. CKD was defined as proteinuria and/or reduced estimated glomerular filtration rate (eGFR) (<60 ml×min(-1)×1.73 m(-2)) in two consecutive follow-up surveys. We used logistic regression models, adjusting for age, sex, and other confounding factor to determine associations between the traits of asthma and CKD. Kaplan-Meier curves were used to analyze patient outcomes.</p><p><b>RESULTS</b>A total of 2354 subjects with complete data were recruited for this study with mean age (45.4±10.4) years. After 6 years of follow-up, 9.6% (n = 227) of the analytic cohort developed proteinuria and 3.1% (n = 72) progressed to eGFR <60 ml×min(-1)×1.73 m(-2). The patients with >20 years asthma history, not well-controlled or persistent asthma patients had higher incidence of proteinuria and reduced eGFR compared with patients with ≤20 years asthma history, at least well-controlled or remission asthma, respectively. The multivariable adjusted OR for proteinuria and reduced eGFR in participants with persistent asthma was 1.49; (95% confidence interval (CI) 1.17-1.91) and 2.07 (95% CI 1.34-4.42). Compared to patients with no asthma traits, there was a significant risk (OR, 3.39; 95% CI 1.36-8.73) for those who met all three traits, including asthma history >20 years, not well-controlled and persistent stage, after adjusting for potential confounding factors.</p><p><b>CONCLUSIONS</b>In this retrospective cohort study, we found that persistent asthma was associated with an increased risk of CKD, which was independent of obesity, diabetes, hypertension, and other well-established risk factors. Future studies should be directed to elucidate the mechanisms underlying the association between asthma and CKD.</p>

Objective To investigate the correlation between the single nucleotide polymorphism(SNP) of macrophage migration inhibitory factor(MIF) gene -173G/C and the susceptibility in patients with juvenile idiopathic arthritis(JIA).Methods Study group consisted of 97 children of JIA.All patients included in this study met the International League of Associations for Rheumatology criteria for JIA.Control group consisted of 102 healthy individuals.Germline DNA was extracted from peripheral blood by AxyPrep blood genomic DNA miniprep kit.Polymerase chain reaction-restrictivon fragment length polymorphism(PCR-RFLP) was used for genotyping the -173G/C polymorphism of MIF.Genotype distribution and allele frequencies were obtained by direct counting.Statistical analysis was performed by using SPSS Bosoftware.Allele and genotype distributions were compared using the chi-square test.The relative risk of alleles was described by odds ratios (OR) and 95% confidence intervals (95%CI).Hardy-weinberg equilibrium was confirmed with the chi-square test.Results We detected 3 kinds of genotypes at the MIF-173 locus.The frequency of each genotype was 54.6%(GG),42.3%(GC),3.1%(CC) in JIA group,and 79.4%(GG),20.6%(GC),0(CC) in control group.The C allele frequencies in the JIA and control group were 24.7% and 10.3%,respectively.There was significant difference was observed between the JIA and control group in the frequencies of mutant genotype(GC and CC) of MIF-173G/C polymorphism(?2=13.872 P=0).Individuals possessing a MIF-173C allele did have an increased risk of JIA(OR=2.79,95% CI 1.62-4.81 P=0).When the genotype and allele distributions of the MIF-173 gene in the subtypes of JIA and contronl group were compared,a significant difference wad found in the systemic JIA and control group (P0.05).Conclusions MIF-173G/C SNP may be associated with the sensitivity of JIA.MIF-173 C allele may increase susceptibility to JIA.
ABSTRACT
Objective To study the correlation between single nucleotide polymorphisms of -238,-308 G/A in promoter region of tumor necrosis factor -?(TNF-?) gene and the type of juvenile idiopathic arthritis (JIA).Methods Clinical data and blood preparation of 127 children with JIA and 106 healthy children were evaluated.Subgroups of JIA were defined according to the Edmonton criteria.The -238 G/A and -308 G/A polymorphisms in DNA analysis in this study were extracted from the whole blood.The restricted fragment length polymorphisms were determined in the cases of all JIA children and control group.Results 1.The TNF-?-238 G/A allele frequencies of JIA group and control group:allele frequency of JIA group was 92.9% and 7.1%,and the control group was 95.3% and 4.7%.The distribution of allele frequencies was no significantly different between JIA group and control group(?2=1.149 P=0.284).But there were significant difference between polyarticular JIA (RF negative) and control group(?2=7.621 P=0.006).2.The TNF-?-308 G/A allele frequencies of JIA group and control group:allele frequency of JIA group was 94.1% and 5.9%,the control group was 95.3% and 4.7%.The distributions of allele frequencies was no significantly different between JIA group and control group(?2=0.322 P=0.571).There were significantly difference between polyarticular JIA (RF negative) and control group (?2=7.621 P=0.006).Conclusions The TNF-?-238,-308 polymorphisms of A in the-238 and-308 TNF-? gene are important to the joint destruction of JIA.The study will be beneficial to provide indirect support to the application of anti-TNF drugs to the treatment of JIA.
ABSTRACT
<p><b>OBJECTIVE</b>To detect the expression of cytokines by acute promyelocytic leukemia (APL) cells before and after exposure to arsenic trioxide.</p><p><b>METHODS</b>Diagnoses were performed according to the FAB cytological classification criteria and cytogenetic criteria. Bone marrow or blood samples from APL patients were collected in heparinized tubes, then primary APL cells were separated by traditional Ficoll-Hypaque density centrifugation and purified after adherence to plastic surfaces. IL-1(beta), IL-6, IL-8, TNF alpha and G-CSF levels in the leukemia cell culture supernatants were detected by ELISA. At the same time, nitro blue tetrazolium (NBT) reduction test was used to detect the differentiation of APL cells.</p><p><b>RESULTS</b>After 96 hours exposure to arsenic trioxide, 10 - 6 mol/L in vitro or 10 mg/d in vivo, APL cells showed a significant increase of IL-1(beta) (P < 0.05) and G-CSF (P < 0.05) production, and a significant decrease of IL-6 (P < 0.05) and IL-8 (P < 0.05). However, there was no obvious variation of TNF alpha when compared with APL cells without exposure to arsenic trioxide. On the other hand, the proliferation ratio of APL cells in vitro was statistically correlated to the IL-1(beta) secretion ratio or G-CSF secretion ratio. The cell number ratio in patients with detectable IL-1(beta) or G-CSF was higher than that without detectable IL-1(beta) or G-CSF.</p><p><b>CONCLUSION</b>IL-1(beta) and G-CSF secretion may play an important role in the proliferation of APL cells after exposure to arsenic trioxide.</p>
