HOXA9 is a member of homeobox gene,and more commonly expressed in leukemia cells,which may be involved in the development and progress of leukemia with Meisl, PBX1 and Trib2. HOXA9 also affects the treatment outcome and prognosis of leukemia, the higher the expression level, the poorer response to treatment, the prognosis is also poor.

Apollon is a member of inhibitor of apoptosis proteins. It can inhibit apoptosis through inter-action with Smac, HtrA2 and caspase. Apollon is highly expressed in a variety of tumors, such as leukemia, breast cancer, brain cancer, carcinoma of mouth and carcinoma of stomach. Apollon may relate with genesis and prognosis of tumor . It also may lead to drug resistance of certain tumors.

Magnetic nanoparticles mediated hyperthermia, as a new kind of tumor therapy, promotes tumor hyperthermia to targered localization and precise control. In recent years, researchers stvdy deeply on surface modification of magnetic nanoparticles, combination with radiotherapy and chemotherapy, as well as clinical application, at the same time, researchers find that superparamagnetic ferrite nanoparticles after obtai-ning water-soluble by surface modification, can be as the MR imaging agent. Magnetic nanoparticles both for tumor diagnosis and treatment, will further promote tumor therapy to a more safe and effective direction.

Bcl-2 family have dual-regulating effects on cell apoptosis mediated by mitoehondrion. The ratio of pro-apoptosis members and anti-apoptosis members closely correlates with tumorigenesis, drug-resist-ance and prognosis. Therefore,Bcl-2 family become important targets in tumor biotherapy. Many strategies have been applied to tumors treatment targeting Bcl-2 family,such as some biological treatment,short peptides and organic small molecules.

According to WHO, breastfeeding is the best for premature babies. Breastfeeding are beneficial for health of both mothers and their premature infatns and as well as reduction of medical and health expenditure. However, the breastfeeding rate in premature infants is still unsatisfactory so far, especially in those premature infants admitted to NICU in the early life. This article review promoting and hindering factors of breastfeeding in hospitalized premature infants from the following aspects:the characteristics of premature infants, the demographic and sociological characteristics, knowledge, beliefs, and psychological status of mothers, hospital policies and support, and family support.

Objective To analyze the therapeutic effect of lidocaine in cervical cancer postoperative urinary retention.Methods Sixty-five patients with cervical cancer postoperative urinary retention were divided into two groups by random digits table method:treatment group 32 cases,immediately after the urethral catheter to infiltrate 1 ml of 2％ lidocaine cotton ball placed urethral opening more than 20 minutes again urine; control group 33 cases,routine for patients with urethral catheter.The incidence of urinary retention and adverse drug reactions were compared between two groups.Results Treatment group residual urine volume was(53 ± 22) ml,1 case(3.12％,1/32) of urinary retention,control group was (163 ± 32) ml and 8 cases (24.24％,8/33),there was significant difference (P ＜ 0.05).Conclusion Lidocaine for cervical cancer postoperative urinary retention has good prevention effect,can be popularized in clinical application.

Mitochondrial disease is a set of multi-systematic and heterogeneous disease which invades in the central nervous system and muscles tissue adequately,mainly refers to the genetic defects that causes mitochondrial structure and function defect.Mitochondrial disease occupies an important position in the human genetics.At present,the research of mitochondrial disease and the related genetic mutation has become the focus in the genetics.This review is to discuss the mitochondrial disease epidemiology,molecular biology and genetics,clinical manifestations and diagnosis.

Objective: To determine whether mannose-binding lectin(MBL) variant alleles were associated with frequent relapses in childhood nephrotic syndrome(NS). Methods: MBL alleles of codon 54 and promoter region at positions-550 and-221 were genotyped by means of Polymerase Chain Reaction-Restricted Fragment Length Polymorphism(PCR-RFLP)and PCR-Sequence-Specific Primers(PCR-SSP)assay in 32 China Han Nationality children with frequently relapsing NS(FRNS) and 31 with non-frequently relapsing NS(NFRNS),as well as in 32 healthy control subjects. Results: In patients with upper respiratory infections before relapses,the mutant genotype(GGC/GAC and GAC/GAC) frequency of MBL codon 54 was higher in children with FRNS(76.0%) than in children with NFRNS(42.9%).The B allele mutation frequency of MBL codon 54 was higher in children with FRNS than in healthy control subjects(34.4% vs 12.5%,P

Objective:To discuss protective mechanism of polydatin(PD)on cerebral ischemia reperfusion injury.Methods:By using rat models of focal cerebral ischemia reperfusion,influence of PD on neuronal apopsis after cerebral ischemia reperfusion injury were examined.Results:Parts of neurons began developing apopsis at 2 hours after reperfusion,.With time passing after reperfusion the number of apoptotic cells increased gradually with peak at 24 hour and thendecreased gradually,The number of apoptotic cells decreased significantly(P

Sepsis is a major cause of mortality among children and newborns.The largest part of the global pediatric sepsis burden occurs in middle-and low-income countries,where the mortality of sepsis reaches 24％-50％.It is necessary to provide clinicians with a framework to improve the management of pediatric septic patients.The key of treatment is to ensure adequate tissue perfusion,to maintain cardiovascular and hemodynamic stability,the administration of adequate antibiotics,the proper use of glucocorticoid,and so on.
