Objective To investigate the level about illness perception in patients with coronary heart disease. Methods From July to De-cember, 2015, 198 inpatients with coronary heart disease who were admitted into hospitals twice or more were enrolled. They were assessed with Illness Perception Questionnaire-Revised (IPQ-R). Results The score of common symptoms was (4.55±1.64). The symptoms, for exam-ple, chest pains, uncomfortable feeling in chest, cold sweat, flustered and breathlessness were most frequently experienced and most often identified. For the illness perception part, the scores on subscales of treatment control and consequences were higher than 3, which was the neutral point. For the cause dimension part, the highest scores was (3.38 ± 0.90) in diet or eating habits, followed by (3.38 ± 0.89) in aging. Among these factors, immune factors had the highest mean score, followed by stress factor. Conclusion The level of illness perception in pa-tients with coronary heart disease was in the middle level, and individual differences were obvious. The awareness of the disease and the in-tervention of the patient should be strengthened.

Objective To investigate the changes in Th17 cells and CD4+CD25+regulatory T lym-phocytes ( Treg) as well as transcription factors and cytokines relating to them in children with Epstein-Barr virus (EBV)-associated hemophagocytic lymphohistiocytosis (HLH) and to analyze their role and clinical significance. Methods Thirty-two children with newly diagnosed EBV-associated HLH in the Hematology/Oncology Department of Zhengzhou Children′s Hospital from January 2012 to December 2016 were enrolled in this study. Thirty healthy children taking physical examination in the same hospital in the corresponding period were recruited as controls. Percentages of Th17 and Treg cells in peripheral blood T lymphocytes were detected by flow cytometry. Expression of RORγt and Foxp3 at mRNA level in peripheral blood mononuclear cells was detected by real-time PCR. Levels of IL-6, IL-17, IL-10 and TGF-β1 in serum samples were measured by ELISA. Results Compared with the control group, the EBV-associated HLH group showed in-creased percentage of Th17 cells [(1. 09±0. 43)% vs (0. 39±0. 19)%, P<0. 05] and enhanced expres-sion of RORγt at mRNA level [(1. 41±0. 37) vs (0. 67±0. 13), P<0. 05], but decreased percentage of Treg cells [(3. 66±1. 13)% vs (6. 80±1. 15)%, P<0. 05] and inhibited expression of Foxp3 at mRNA level [(15. 97±5. 11) vs (30. 23±4. 95), P<0. 05]. All of the above mentioned changes were reversed af-ter treatment (P<0. 05). Serum levels of IL-6 and IL-17 of EBV-associated HLH group were higher than those of control group, while serum levels of IL-10 and TGF-β1 were lower (P<0. 05). Conclusion Im-balanced Th17/Treg cells might play an important role in the pathogenesis of EBV-associated HLH. Cyto-kines relating to the maintenance of Th17/Treg cell balance could be used as indicators of disease develop-ment.

Purpose:
Progressive familial intrahepatic cholestasis (PFIC) is a rare genetic autosomal recessive disease caused by mutations in ATP8B1, ABCB11 or ABCB4. Mutational analysis of these genes is a reliable approach to identify the disorder.
Methods:
We collected and analyzed relevant data related to clinical diagnosis, biological investigation, and molecular determination in nine children carrying these gene mutations, who were from unrelated families in South China.
Results:
Of the nine patients (five males, four females) with PFIC, one case of PFIC1, four cases of PFIC2, and four cases of PFIC3 were diagnosed. Except in patient no. 8, jaundice and severe pruritus were the major clinical signs in all forms. γ-glutamyl transpeptidase was low in patients with PFIC1/PFIC2, and remained mildly elevated in patients with PFIC3. We identified 15 different mutations, including nine novel mutations (p.R470HfsX8, p.Q794X and p.I1170T of ABCB11 gene mutations, p.G319R, p.A1047P, p.G1074R, p.T830NfsX11, p.A1047PfsX8 and p.N1048TfsX of ABCB4 gene mutations) and six known mutations (p.G446R and p.F529del of ATP8B1 gene mutations, p.A588V, p.G1004D and p.R1057X of ABCB11 gene mutations, p.P479L of ABCB4 gene mutations). The results showed that compared with other regions, these three types of PFIC genes had different mutational spectrum in China.
Conclusion
The study expands the genotypic spectrum of PFIC. We identified nine novel mutations of PFIC and our findings could help in the diagnosis and treatment of this disease.

Objective:To explore the expression of fructose bisphosphate aldolase A (ALDOA) in the bone marrow of patients with acute myeloid leukemia (AML) and the correlation with clinical features and prognosis.Methods:The bone marrow samples of 90 newly diagnosed AML (non-acute promyelocytic leukemia) patients and 18 allogeneic hematopoietic stem cell transplantation donors who were treated from January 2013 to December 2015 in the First Affiliated Hospital of Zhengzhou University and the Children's Hospital Affiliated to Zhengzhou University were collected. The relative expression level of ALDOA mRNA in bone marrow samples was detected by using real-time quantitative polymerase chain reaction (qRT-PCR). Clinical data of these patients were retrospectively analyzed, and the patients were divided into continuous complete remission (CR) group and refractory recurrent (RR) group according to the clinical response and follow-up results. The differences of the relative expression level of ALDOA mRNA between AML group and the normal control group, CR group and RR group were analyzed. Univariate and multivariate Cox regression risk model were used for analysis of factors influencing prognosis of AML patients.Results:The relative expression level of ALDOA mRNA in AML group was higher than that in normal control group [(5.71±0.44) vs. (1.10±0.08), t = 4.74, P<0.001]. The relative expression level of ALDOA mRNA in the RR group was higher than that in the CR group [(6.69±0.67) vs. (4.30±0.36) , t = 2.79, P < 0.001]. In addition, there were statistically significant differences in the proportion of patients with ALDOA mRNA high expression and those with ALDOA mRNA low expression stratified by the number of white blood cell, the proportion of bone marrow blasts and whether complete remission could be achieved or not after 1 course of induction therapy (all P < 0.05). Overall survival in patients with ALDOA high expression was worse than that in patients with ALDOA low expression ( χ2 = 5.59, P = 0.018). Multivariate analysis showed that white blood cell count, prognosis stratification, whether complete remission could be achieved or not after 1 course of induction therapy and ALDOA expression were the independent prognostic factors for the death of AML patients (all P < 0.05). Conclusions:ALDOA may play an important role in the development and progression of AML, and the expression level of ALDOA in the bone marrow can be used as an index for the prognosis assessment of AML patients and may be a potential therapeutic target for AML.
