ABSTRACT
Objective To study the clinical significance of antinuclear antibody (ANA),anti-thyroid peroxidase antibody (TPO-Ab) and antithyroglobulin antibody (Tg-Ab),thyroid stimulating hormone (TSH),free triiodothyronine (FT3),free thyroxine (FT4) in patients with recurrent spontaneous abortion (RSA).Methods 46 women with RSA diagnosis in out patient department in Peking University Shenzhen Hospital from March 2015 to December 2016 were recruited as the study group,20 women with normal childbirth history were enrolled as the control group,ANA was detected by indirect immunofluorescence (IIF) assay and ELISA,TSH,FT3 and FT4 were detected by chemiluminescence immunoassay technology.Results The positive rates of ANA(IIF),TPO-Ab and Tg-Ab in patients with RSA were 24％,24％ and 15％ respectively which were significantly higher than those in healthy control (P＜0.05).Serum levels of TSH,TPO-Ab and Tg-Ab in patients with RSA were 2.70 ± 1.38 mIU/L,38.99 ± 10.18 IU/ml and 3.07 ± 1.69 IU/ml respectively,which were significantly higher than those in healthy cases (P＜0.05).Conclusion ANA and antithyroid antibodies were closely related with RSA.It is very important to screen ANA and antithyroid antibodies for etiological diagnosis and appropriate intervention in patients with RSA to reduce the incidence of abortion.
ABSTRACT
Objective To explore the application value of serum procalcitonin (PCT ) and amyloid protein A (SAA ) in the early diagnosis and curative evaluation of bacterial infectious diseases among preschool children in order to improve the clinical diagnosis level of early bacterial infection .Methods A total of 120 cases of pediatric infectious diseases in our hospital from January to De‐cember 2015 were selected and divided into the bacterial infection group (60 cases) and viral infection group (60 cases) ,meanwhile 50 children undergoing the physical examination were selected as the control group .The serum levels of PCT and SAA were ob‐served and compared among the three groups ,and the statistical analysis was performed by using the SPSS 19 .0 software .Results The levels of PCT and SAA in the bacterial infection group were significantly increased compared with the viral infection group and the healthy control group(P<0 .05) ,both PCT and SAA levels after effective antibiotic treatment were significantly decreased (P<0 .05);the positive rates of PCT and SAA in the bacterial infection group were 91 .7% and 95 .0% respectively ,which were signifi‐cantly higher than those in the viral infection group and the healthy control group (P<0 .05) ,the sensitivity of PCT in the diagno‐sis of bacterial infection was lower than that of SAA ,but the specificity ,positive predictive value and negative predictive value were all higher than those of SAA ,the correlation analysis showed that PCT level in the bacterial infection group was positively correla‐ted with and the SAA level(r=0 .782 ,P<0 .01) .Conclusion Detecting the PCT and SAA levels is conducive to early diagnosis , judgment of the disease condition and guidance of rational medication in bacterial infection among preschool children ,in which the efficiency of PCT for diagnosing bacterial infection is superior to SAA .
ABSTRACT
Objective To investigate the diagnostic value of combined detection of neutrophil CD64 index and C reactive protein (CRP) levels in newborn bacterial infectious diseases .Methods The retrospective analysis was performed on 139 neonates admitted to the neonatal department of our hospital from January to December 2015 ,including 72 cases in the bacterial infection group and 67 cases in the viral infection group ,and 50 healthy neonates were selected as the control group .The levels of CD64 and CRP and the positive rates were compared among 3 groups and analyzed .The sensitivity ,specificity ,positive predictive value and negative predictive value of CD64 and CRP in the diagnosis of bacterial infection were analyzed .Results The CD64 index and CRP levels had statistical difference between the bacterial infection with the viral infection group and normal control group (P<0 .05) ,the CD64 index and CRP levels after treatment in the bacterial infection group were significantly decreased ,the differences were statistieally significant(P<0 .05) .The sensitivity ,specificity ,positive predictive value and negative predictive value of CD64 index in the diag‐nosis of bacterial infection were 91 .7% ,92 .5% ,93 .0% and 91 .2% respectively ,which were significantly higher than those of CRP ,the differences were statistically significant (P< 0 .05).CD64 index was positively correlated with CRP (r= 0 .781 ,P<0 .01) .Conclusion The combined detection of CD64 index and CRP level helps to early diagnosis ,differential diagnosis and the therapeutic effect evaluation of bacterial infection in neonates ,moreover the diagnostic efficiency of CD64 is obviously better than that of CRP .
ABSTRACT
Objective To detect hs‐cTnT and cTnI for exploring their application value in the early diagnosis of acute myocardial infarction(AMI) .Methods From October 2015 to March 2016 ,100 patients with AMI in the cardiology department of our hospital were selected as the observation group(AMI group) and contemporaneous 100 adults undergoing physical examination as the con‐trol group .The chemiluminescence immunoassay was used to detect the levels of hs‐cTnT and cTnI .The positive rate ,sensitivity and specificity of the hs‐cTnT and cTnI in the AMI group for early diagnosis of AMI were compared .Results The level of hs‐cT‐nT in the AMI group was (4 .89 ± 1 .83)ng/mL ,which was higher than that in the healthy population by 99 percentile value 0 .014 ng/mL ;the cTnI level in the AMI group was (28 .82 ± 12 .32)ng/mL ,which was higher than that in the healthy population by the upper limit of normal reference value 0 .4 ng/mL ,both of them were significantly higher than those in the control group ( P<0 .05) ,the positive rate and sensitivity of hs‐cTnT was both 92 .0% ,which was significantly higher than 79 .0% of cTnI both(P<0 .05) ,the specificity of cTnI was 96 .0% ,which was significantly higher than 76 .0% of hs‐cTnT(P<0 .05) .Conclusion The pos‐itive rate and the sensitivity of hs‐cTnT are high ,the specificity of cTnI is high ,their joint detection has an important significance for the early diagnosis of AMI .
ABSTRACT
@#The motor function of the trunk in 10 hemiplegic patlents was evaluated with Biodex Sys- tem Ⅱisokinetic testing aparatus. The result shows that the strength of flexors and extensors of the trunk,especially the flexors,becomes weaker(The ratio of flexors to extensors is less than 1).The patients weretreated with a series of the trunk retraining methods. The motor function of the trunk was improved aftertreatment(P<0.01 ).The total motor function(Fugl-Meyer Assessing Scale)also makes significant progress(P<0.01).The study proposes that the retraining and regaining of the trunk motor function in hemiplegiais quite important not only to the trunk but also to total motor function.
