The next-generation sequencing (NGS), as the most practical and reliable method, has replaced the classical Sanger sequencing to help scientists to discover the genetics secrets of human tumor diseases. With the technique development, the whole genome sequencing will be no longer out of reach. Recently, some scientists used the NGS in the research of hematological malignancies and pushed the progress of the whole genome sequencing in acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) actively in order to find out the pathogenesis of some hematological malignancies. The NGS and the application of the whole genome sequencing, the exome sequencing, the transcriptome sequencing in AML and MDS are reviewed in this article.

OBJECTIVETo observe the effect of Qiju Dihuang Pill (QDP) on changes of Chinese medical syndrome types in pregnant women of Gan-Shen yin deficiency syndrome (GSYDS), and to explore the correlation between imbalanced cytokine levels and GSYDS.

METHODSThis was a random controlled trail. A total of 163 pregnant women of GSYDS at 12 -16 gestational weeks were randomly allocated into the experimental group (86 cases) and the control group (77 cases). Patients in the experimental group took QDP for 2 -4 weeks. Changes of Chinese medical syndrome types and serum interferon-gamma (IFN-gamma) and interleukin-4 (IL-4) levels were observed and compared between the two groups before and after treatment.

RESULTS(1) Totally 41 patients (47.7%) in the experimental group were transformed to normal Chinese medical syndrome type. In the same period of the follow-ups, 9 patients (11.7%) in the control group were transformed to normal Chinese medical syndrome type, showing statistical difference (P < 0.05). (2) In the experimental group, the serum level of IFN-gamma and the ratio of IFN-gamma/IL-4 in the peripheral blood were obviously lower after treatment than before treatment (P < 0.01), and obviously lower than those in the control group (P < 0.01). The level of IL-4 after treatment in the experimental group was higher than that before treatment, and also higher than that in the control group, but with no statistical difference.

CONCLUSIONSThese results indicated that there was imbalanced IFN-gamma/IL-4 ratio in the peripheral blood of pregnant women of GSYDS. QDP might play a role in immunoregulation by affecting the IFN-gamma level.

Objective To evaluate the clinical efficacy of salmeterol/fluticasone propionate combined with bailing capsule in the treatment of chronic obstructive pulmonary disease ( COPD).Methods Eighty cases with COPD were recruited in this study from Dec 2011 to Feb 2013.The included subjects were randomized divided into experiment group (n=38) and control group (n=42).Patients in experiment group were given salmeterol/fluticasone propionate (50 μg/100 μg) combined with bailing capsule 3 g? d-1 , while patients in the control group were given salme-terol/fluticasone propionate only.After 6 -month treatment, the data of forced expiratory volume in one second ( FEV1 ) , forced vital capacity(FVC), FEV1/FVC and 6 minutes walking test(6MWT) were recorded and compared between two groups. Results The data of FEV1, FVC, FEV1/FVC and 6MWT were all improved after 6-month treatment in the groups ( P <0.05 ) .The onset rate in the experiment group was much lower than that in the control group [ ( 2.8 ±1.9 ) vs (4.1 ±2.1), P<0.05], and the COPD stable period in the experiment group was much longer than that in the control group [(209.3 ±34.2) vs (47.2 ±54.3), P<0.05].Conclusion The salmeterol/fluticasone propionate combined with bailing capsule can significantly prevent the COPD patients from acute seizures, and the quality of life would be improved.

This study was purposed to explore the expression of p57kip2 in the bone marrow of patients with de novo myelodysplastic syndrome (MDS) and its role in MDS pathogenesis, as well as the relationship between the expression of p57kip2 and SDF-1/CXCR4 signal. The expression of p57kip2 and CXCR4 in 67 de novo MDS patients was measured by real-time quantitative PCR. The percentage of CD34(+) cells in the bone marrow from MDS patients was measured by flow cytometry. 18 healthy volunteers were recruited for control. The effect of SDF-1 on p57kip2 expression in bone marrow mononuclear cell (BMMNC) from MDS or normal controls was investigated in vitro, and difference between them was compared. The results showed that low-risk MDS and high-risk MDS displayed a significant reduction of p57kip2 mRNA expression in BMMNC compared with that in control group (P < 0.001) and there was a negative correlation between p57kip2 expression and percentage of CD34(+) (r = -0.458, P < 0.001); the patients with abnormal karyotype showed lower expression of p57kip2 gene, compared to patients with normal karyotype (P = 0.045). Although the expression of CXCR4 had no difference between MDS patients and normal controls, a positive correlation between p57kip2 and CXCR4 in MDS patients was still found (r = 0.609, P < 0.001). Moreover, SDF-1 increased p57kip2 expression in normal BMMNC in dose-dependent manner, but BMMNC from MDS patients showed no response to SDF-1. SDF-1-induced p57 expression was blocked by AMD3100. It is concluded that the low expression of p57 gene in MDS may play a role in the pathogenesis of MDS. Furthermore, SDF-1-induced p57kip2 expression in BMMNC, and the decreasing response of BMMNC to SDF-1 may contribute to the low expression of p57kip2 in MDS patients.

OBJECTIVETo study the methylation status of p73 gene promoter in patients with myelodysplastic syndrome (MDS) and explore its significance with clinical prognosis.

METHODSMethylation of p73 promoter was detected in bone marrow cells from 135 MDS patients and 13 healthy controls by methylation-specific PCR (MSP). The results of MSP were confirmed by bisulfite sequencing. The expression of p73 mRNA was detected by real-time quantitative PCR. Primary bone marrow cells from MDS patients were treated with decitabine, the changes of p73 methylation status and p73 mRNA expression were measured. The role of p73 methylation in the prognosis of MDS and the correlated clinical data were explored.

RESULTSp73 hypermethylation was present in 37.04% of MDS cases and patients with high risk MDS (RAEB-1 and RAEB-2) exhibited a significantly higher frequency of p73 methylation than that of low risk MDS (58.8% vs 29.7%, P = 0.002). The expression of p73 mRNA in the methylated group was decreased compared to that of the unmethylated group (P = 0.032). Decitabine treatment decreased the level of p73 methylation and increased the level of p73 transcripts. Patients with p73 methylation progressed rapidly to AML (P < 0.001) and had shorter survival (P = 0.002) than those who did not have p73 methylation. In the multivariate Cox regression model, BM blast and p73 methylation status emerged as independent prognostic factor for overall survival and leukemia free survival.

CONCLUSIONp73 gene methylation is common in patients with MDS and may indicate poor prognosis. p73 may be a therapeutic target in MDS.

Hepcidin can regulate cell irons' efflux transport. The expression of hepcidin can be influenced by the body signals (such as serum ferritin and erythropoietin levels) as well as inflammation, hypoxia and other disease states. These stimulus activate the signaling pathway of BMP-the SMAD, the JAK-STAT and HIF1 through the liver parenchymal cell surface type I transmembrane glycoprotein of HFE, transferrin receptor 1, 2, hepcidin regulatory proteins, thereby changing the hepcidin gene transcription, regulating the expression levels of hepcidin. However, the molecular mechanism that regulate hepcidin expression is unclear. From the signal factors that affect hepcidin expression and signaling pathways involved in its expression, the latest research progress on regulatory mechanism of hepcidin are summarized.

OBJECTIVETo study the clinic application of compound flap pedicled with arterial arch of palpebral margin in repairing severe full defect of eyelid.

METHODSAccording to eyelid structure and the defect size, the two compound flaps were designed beside the defect based on the arterial arch of the palpebral margin. If the defective area was too large, the lateral compound flap may be extended to lower or upper eyelid 0.5 cm away from the outer canthus, then cut and propelled the two compound flaps to repair the full eyelid defect.

RESULTS20 cases had been cured with this method since 1998. In this cases, 4 cases were basal cell carcinoma of eyelid, 2 cases were squamous carcinoma, 3 angiomas, 6 chromatophore nexuses, 3 traumatic defects, 2 congenital defects. The largest length of eyelid full defect was 1.7 cm and the smallest was 0.8 cm. 6 cases were upper eyelid defect and 14 cases were lower eyelid defect. All the compound flaps survived completely without any complications. All cases obtained satisfactory results functionally and esthetically.

CONCLUSIONSRepairing full eyelid defect with the compound eyelid flap is the same kind tissue repairing. It can not only provide enough tissues to primary repair large full defect of the upper or lower eyelid to restore normal anatomical structure and appearance of the eyelid, but also is easy to be operated without severe secondary deformities. The arterial arch of the palpebral margin is constant and the blood supply of the compound flap is reliable. It is an ideal method of repairing the eyelid defect.
