ABSTRACT
Objective To explore the diagnostic value of the quantitative detection of plasma miRNA-125b and miRNA-133b in children with asthma.Methods Thirty asthmatic patients were enrolled in this study and collected the blood specimens during acute phase and stable phase respectively (AP group and SP group).Thirty allergic rhinitis children (AR group) and thirty healthy children were recruited to the control group (NC group).The levels of miRNA in different groups were detected by qRT-PCR.The performance of miRNA-125b and miRNA-133b were evaluated by receiver operating characteristic curves (ROC) and the area under the curve (AUC) (95％CI).Results The relative expression of miRNA-125b in AP group and SP group were significantly higher than A R group (t=3.913,3.120,P＜0.01),miRNA-133b.In AP group and AR group the expression of miRNA-133b were significantly higher than control group (t=4.426,4.720,P＜0.01).The detection of miRNA-125b yielded an area under the curve of ROC of 0.7989,(95 ％ CI:0.7111～ 0.8864) in discriminating asthmatic patients from healthy group.And the miRNA-133b was 0.7274 (95％CI:0.586 5～0.863 0) in discriminating asthmatic patients during the acute phase from healthy group.Conclusion The relative expression of miRNA-125b in children with asthma was significantly higher than that in AR group and NC group,miRNA-125b may prove to be a non-invasive biomarker for the auxiliary diagnosis of asthma especially when the relative expression up to 1.998.
ABSTRACT
Objective To explore the diagnostic value of the quantitative detection of miRNA-145 and miRNA-143 in the ser-um of children with Kawasaki disease (KD).Methods In this study,45 KD cases were enrolled and were divided into 19 ca-ses with coronary artery lesions (CAL group)and 26 cases without coronary artery lesions (NCAL group).Thirty healthy children were recruited as the control group (NC group).qRT-PCR was conducted to detect the expression of miRNA-145 and miRNA-143 in serum of each group.The diagnostic value of miRNA-145 and miRNA-143 were evaluated by receiver op-erating characteristic curves (ROC)and the area under the curve (AUC)(95%CI).Results The relative expressions of miRNA-145 and miRNA-143 in the serum of the CAL group in acute phase were 2.33±1.26 and 1.64±0.50,which were respectively higher than the control group,with statistically significant difference (t=5.108,5.072,P0.05).During the acute phase of NCAL group, the relative expressions of miRNA-145 and miRNA-143 were 2.02±1.00 and 1.63±0.50 respectively.They were signifi-cantly higher than the control group (t=4.746,5.261,P0.05).The critical value of miRNA-145 for diagnosis of KD was 1.697 with sensitivity of 64.44% and specificity of 90% and yielded an area under the curve of ROC of 0.7733 (95%CI:0.667 0~0.879 7).Also,the critical val-ue of miRNA-143 was 1.361 with sensitivity of 64.44% and specificity of 86.67% and yielded an area under the curve of ROC of 0.8163 (95%CI:0.722 5~0.910 0)in discriminating KD from healthy group.Conclusion miRNA-145 and miR-NA-143 may prove to be a non-invasive biomarker for the auxiliary diagnosis of KD.
ABSTRACT
Objective To investigate the relationship between red cell distribution (RDW) and serum inflammatory factor in di‐lated cardiomyopathy (DCM ) patients .Methods 47 dilated cardiomyopathy patients and 40 healthy volunteers were chosen .Ac‐cording to NYHA classification ,12 patients in NYHA class Ⅱ ,15 patients in NYHA class Ⅲ and 20 patients in NYHA class Ⅳ . RDW ,High sensitivity C‐reaction protein (hs‐CPR) ,tumor necrosis factor‐α (TNF‐α) and interleukin‐1β (IL‐1β) were detected in all the DCM patients and healthy volunteers .The correlation between RDW and serum inflammatory factors were analyzed . Results Compared to healthy volunteers ,RDW ,hs‐CRP ,TNF‐α and IL‐1β were elevated significantly in DCM patients (all P<0 .05) .Comparisons among the DCM patients groups ,RDW ,hs‐CRP ,TNF‐α,IL‐1β in NYHA class Ⅲ and NYHA class Ⅳ were higher than those in NYHA class Ⅱ(all P<0 .05) .There were positive correlation between RDW and hs‐CRP ,RDW and TNF‐α, RDW and IL‐1β(r=0 .422 ,0 .390 ,0 .325 ,P<0 .05) .Conclusion RDW is one of the indicators evaluating cardiac functions ,and there is a significant correlation between RDW and serum inflammatory factors in DCM patients .
ABSTRACT
Objective To investigate the serum and urine levels of neutrophil gelatinase‐associated lipocalin(NGAL) in patients with primary hypertension and related clinical significance .Methods A total of 107 patients with primary hypertension and 100 healthy subjects were enrolled ,and detected for serum and urine levels of NGAL and urinary micro‐albumin .Results Serum and u‐rine levels of NGAL in hypertension patients were (1 .98 ± 1 .49) and (1 .29 ± 0 .54)μg/L ,higher than the (0 .69 ± 1 .02) and (0 .55 ± 0 .35)μg/L in healthy subjects(P< 0 .05) .Urinary micro‐albumin level in hypertension patients was also higher than healthy subjects (P<0 .05) .Conclusion Serum and urine levels of NGAL in patients with primary hypertension could be signifi‐cantly increased ,which might be with important clinical significance in diagnosis ,treatment and prognosis of hypertensive nephropa‐thy .
ABSTRACT
Objective To study the infection rate and sensitivity of genitourinary tract mycoplasma among the patients in the traditional Chinese medicine(TCM) hospital ,and its similarities and differences with the western medicine hospital ,thus to increase the therapeutic effect by combining with the related therapeutic measures of TCM .Methods The mycoplasma identification and drug susceptibility test results in 4 086 female genital tract specimens were performed the retrospective analysis .Then the medica‐tion strategy was investigated by combining with clinic .Results Of the 4 086 specimens ,1 891 cases were Mycoplasma positive with the total positive rate of 46 .3% ;in which the positive rate of ureaplasma urealyticum(UU) was higher(40 .7% ,1663 cases) , the most sensitive drugs were pyostacin and josamycin with the sensitive rates of 99 .11% and 99 .01% respectively ;mycoplasma hominis(M H) was less with the positive rate of 2 .7% (110 cases) ,josamycin and doxycycline were sensitive;the positive rate of UU and M H was 2 .9% (118 cases) ,doxycycline and pyostacin were sensitive with the sensitive rates of 95 .77% and 95 .26% re‐spectively .Conclusion Mycoplasma has higher infection rate in the genitourinary tract among gynecological patients ,the results are similar between the hospital of TCM and Western medicine hospital ;UU is mainly Mycoplasma type;the drug susceptibility test re‐sults reveal that the empirical medication for anti‐mycoplasma infection can select doxycycline and josamycin;it is recommended that the combined therapy with syndrome differentiation of traditional Chinese medicine by combining with the drug sensitivity test re‐sults has better clinical efficacy .
