ABSTRACT
Objeetive To explore the situation of rotavirus infection and extraintestinal organe damage in children in Yueqing city.Methods Two hundred and eighty-seven cases with acute rotavirus gastroenteritis in our hospital were analyzed for prospective study from October 2011 to January 2013 by stool tests.Results Rotavirus infection was found to be more common in autumn and winter.There were 223 cases (17.7％) got extraintestinal organe damage,175 cases (60.80％) got myocardial lesion,and 78 cases (27.18％) got respiratory infection.At the same time,there were 51 cases (17.77％) and 21 cases (7.31％) got liver function lesion and convulsion respectively.Among the metabolic acidosis(48 cases),39 cases were combined with myocardial lesion.While non metabolic acidosis were 239 cases (81.25％),and 136 cases were combined with myocardial lesion.Therefore,the myocardial lesion was significant correlation with metabolic acidosis (P ＜ 0.01).Iron deficiency anemia was 123 cases and combined with 15 cases (12.19％) convulsion,while the convulsion prevalence rates of non iron deficiency anemia was 6 cases (3.65 ％).There was a statistically significant difference between the convulsion prevalence rates of iron deficiency anemia and that of non iron deficiency anemia (P ＜ 0.01).Conclusion Rotavirus diarrhea can lead to extraintestinal organe damage,and the clinical doctors should pay attention to them.
ABSTRACT
ObjectiveTo evaluate prognosis and its clinical factors in patients with primary pontine hemorrhage. Methods Patients with primary pontine hemorrhage who were hospitalized in the First Affiliated Hospital of Wenzhou Medical College within 24 hours after stroke onset between April 2007 and April 2009 were registered conscutively. The patients were followed up for one year. Kaplan-Meier methods were used to analyze survival rate. Cox proportional hazards model was used to study risk factors for 1-year mortality. ResultsA total of 41 patients with primary pontine hemorrhage were studied. Their mean age was (63.5 ± 10. 1 ) years.The overall 1-year mortality rate was 61.0％, the median survival time was (80. 0 ±54.4) days (95％ CI 0-186. 64). After one-year follow-up, the mortality rate in patients with primary dorsal pontine hemorrhage( 18.2％ ) was significantly lower than that in patients with primary ventral pontine hemorrhage(72. 7％ ; x2 = 8. 800, P = 0. 003 ). Patients with massive primary pontine hemorrhage had significantly higher mortality rate than patients with dorsal primary pontine hemorrhage( x2 = 8. 927, P =0. 003). The average hematoma volume of the survivor group and mortality group was (3. 043 ± 1. 718) ml and (5. 984 ± 2. 707) ml, respectively, showing statistical significance (t = 3. 661, P = 0. 001 ). Analysis with Cox proportional hazards model showed that the risk factors associated with mortality were hematoma location ( RR = 2. 428, 95 ％ CI 1. 055-5. 587 ), hematoma volume ( RR = 1. 283, 95 ％ CI 1. 044-1. 577 ),GCS score on admission(RR =3. 389, 95％ CI 1. 177-9. 756). Patients with pontine hematomas in dorsal had a significantly better outcome than in other locations.Conclusions The survival and prognosis in primary dorsal pontine hemorrhage are better than with hemorrhaging in other parts of pontine. A significant correlation was observed between poor prognosis and hematoma volume, hematoma location and GCS score on admission.
ABSTRACT
Objective To investigate the correlation between matrix metalloproteinase-3 (MMP-3)serum level and polymorphism(5A/6A) and the stability of carotid plaque in Chinese Han population.Methods Two hundred and eighty acute cerebral infarction patients from the department of neurology of Taizhou Hospital were divided into carotid vulnerable plaque group and carotid stable plaque group according to the results of carotid B-mode uhrasonngraphy.Serum MMP-3 level waa measured by means of enzyme-linked immunosorbent assay (ELISA).At the same time, genotype was determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) for the common 5A/6A functional promoter polymorphism of the MMP-3 gene.The serum MMP-3 level and genotype frequencies of the MMP-3 gene between the two groups were analyzed.Results The genotype frequencies of the MMP-3 gene 5A/6A polymorphism of the two groups were in Hardy-Weinberg equilibrium The genotype distribution of the MMP-3 promoter 5A/6A polymorphism between the carotid vulnerable plaque group and the carotid stable plaque group was significantly different(χ2 =6.13, P =0.01, OR = 1.90, 95% CI 1.14-3.15).The frequencies of 5A allele were 20.6% and 12.8% in the carotid vulnerable plaque group and the carotid stable plaque group respectively (χ2=6.09, P=0.01, OR =1.76, 95%CI 1.12-2.77).Serum level of MMP-3 in the carotid vulnerable plaque group was higher than that in the carotid stable plaque group (t = 3.39, P =0.00).Conclusion The present findings suggest that serum level of MMP-3 and genetic polymorphism of 5A/6A in MMP-3 promoter are related with carotid vulnerable plaque in Chinese Han population and 5A allele may be a susceptible predictor of carotid vulnerable plaque.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the association of matrix metalloproteinase-3 (MMP-3) serum level and the promoter 5A/6A polymorphism of the MMP-3 gene with atherosclerotic cerebral infarction (ACI) in a Chinese Han population.</p><p><b>METHODS</b>Two hundred and fifteen patients with acute ACI from the Department of Neurology of Taizhou Hospital and 226 healthy controls were included in the study. Serum MMP-3 level was measured by enzyme-linked immunosorbent assay (ELISA). Genotype was determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) for the common 5A/6A functional promoter polymorphism of the MMP-3 gene.</p><p><b>RESULTS</b>The genotype distribution of the MMP-3 promoter 5A/6A polymorphism between the ACI patients group and the control group was significantly different (chi (2)= 9.389, P= 0.002). The frequencies of the 5A allele were 14.2% and 7.7% in the ACI patients group and the control group respectively (chi (2)= 9.430, P= 0.002). Serum level of MMP-3 in the ACI patients group was significantly higher than that in the control group (t= 24.867, P= 0.000). Among the ACI patients group, serum MMP-3 levels also had significant difference between the 5A/6A+ 5A/5A and the 6A/6A genotype (t= 2.057, P= 0.041).</p><p><b>CONCLUSION</b>The present findings suggest that serum level of MMP-3 obviously increased within 48 hours of ischemic stroke and the genetic polymorphism of 5A/6A in the MMP-3 promoter is associated with ACI and MMP-3 expression in the Chinese Han population.</p>
