Changes of serum heart type fatty acid binding protein and brain natriuretic peptide and their clinical significance in children with Kawasaki disease / 中国小儿急救医学

Objective To explore the serum levels changes of heart-type fatty acid-binding protein and brain natriuretic peptide in children with Kawasaki disease,as well as their links with the heart function. Methods A total of 53 children with Kawasaki disease admitted to our hospital from February 2008 to March 2012 were selected and at the same time 50 healthy controls were randomly selected. The serum levels for the children in acute phase,recovery period of Kawasaki disease and control group children were determined by en-zyme-linked immnoabsorbent assay. The internal diameter of coronary artery,LVEF,LVSF,CI and E/A of chil-dren were measured by two-dimensional echocardiography. Results The heart-type fatty acid-binding protein and brain natriuretic peptide concentrations of children with Kawasaki disease in acute stage[(18. 23 ± 13. 81) ng/ml,(517. 2 ±213. 2) pg/ml] were higher than those in recovery stage[(6. 29 ± 1. 26) ng/ml,(92. 1 ± 46. 0) pg/ml](P<0. 05). They were also higher for children in acute stage than those of control group[(6. 26 ± 1. 60) ng/ml,(37. 6 ± 7. 6) pg/ml]. The LVEF,LVSF,CI of Kawasaki disease for children in acute stage were lower than those in recovery phase[(60. 3 ± 3. 6)% vs. (64. 8 ± 4. 3)%,(30. 6 ± 2. 5)% vs. (34. 9 ± 1. 9)%,(3. 1 ± 0. 3)% vs. (3. 5 ± 0. 3)%]. Linear correlation analysis showed the heart-type fatty acid-binding protein and brain natriuretic peptide′concentrations in Kawasaki disease were negatively correlated with LVEF (P<0. 05). The heart-type fatty acid-binding protein′positive rates were also higher than brain natriuretic peptide for the children in acute and recovery phase. Conclusion The heart-type fatty acid-binding protein and brain na-triuretic peptide could be used as the biochemical markers for myocardial damage of children with Kawasaki dis-ease. The heart-type fatty acid-binding protein was more significant than brain natriuretic peptide. The heart-type fatty acid-binding protein and brain natriuretic peptide in Kawasaki disease were also high in recovery stage,indi-cating that myocardial damage could maintain for a long period after the clinical improvement.

A study on diagnostic value of serum human epididymis protein 4 detection for ovarian cancer / 国际检验医学杂志

Objective To investigate the diagnostic value of serum human epididymis protein 4 (HE4 ) for ovarian cancer . Methods Electrochemiluminescence immunoassay was employed to detect the serum HE 4 of 91 patients with ovarian cancer (ovari-an cancer group) ,69 patients with benign ovarian disease(benign group) and 60 healthy people(control group) .Area under the curve(AUC ) of receiver operator characteristic (ROC ) curve for HE4 was calculated .Results Serum HE4 level [(146 .81 ± 81 .29)pmol/L] of patients in ovarian cancer group was significantly higher than those in control group [(43 .16 ± 25 .64) pmol/L] and benign group[(59 .86 ± 39 .87) pmol/L](P<0 .01) .Set serum HE4≥140 pmol/L as positive cutoff value ,the diagnostic sensi-tivity of serum HE4 detection for ovarian cancer was 82 .4% (75/91) ,specificity 89 .9% (62/69) and diagnostic efficiency 85 .6% . Serum HE4 levels of patients with serous adenocarcinoma ,endometrial adenocarcinoma or other ovarian cancer were markedly high-er than that with mucinous adenocarcinoma (P<0 .01) .Serum HE4 levels of patients with stage Ⅲ ,Ⅳ ovarian cancer were obvious-ly higher than those with Ⅰ ,Ⅱ stage(P<0 .01) .Conclusion HE4 detection has clinical value for the auxiliary diagnosis of ovarian cancer .

The Investigation of venous blood cell reference interval for 3-14 years old healthy children in Nanhai district of Foshan city / 国际检验医学杂志

Objective To establish the reference interval of 3-14 years old children in Nanhai district of Foshan city .Methods 2 032 cases of 3-14 years old healthy children were detected and analyzed using MINDRAY BC-5800 automatic blood cell analy-zer .The levels of WBC ,RBC ,Hb ,PLT ,Hct ,MCV ,MCH ,MCHC ,RDW were analyzed .Results The levels of WBC ,RBC ,Hb , PLT ,Hct ,MCV ,MCH ,MCHC ,RDW in 2 031 cases were non normal distribution .The levels of Hb ,Hct had no statistical signifi-cance between male children and female children (P>0 .05);The levels of WBC ,RBC ,PLT ,MCV ,MCH ,MCHC ,RDW had statis-tical significance between male children and female children (P<0 .05) .Conclusion It is very important to establish the reference interval of 3-14 years old children in Nanhai district of Foshan city .

Intellectual property rights system of hospitals and the safeguard mechanism / 中华医院管理杂志

Intellectual property rights system and its safeguard mechanism are critical and fundamental for intellectual property rights of hospitals, yet few academic studies have been made in this regard. The author defined the content of various intellectual property rights of hospitals, along with discussions and summary for the inner structure of such intellectual property rights. Based on objective analysis of the vulnerabilities causing loss of intellectual property rights of hospitals in China, the author came up with three mechanisms for loss prevention, remedy and development. These recommendations are designed to build a relatively complete intellectual property rights system and the safeguard mechanism for hospitals.
