Oxytocin ( OT ) is a cyclic neuropeptide containing nine amino acids residues, in addition to the traditional roles of uterine contraction and lactation, it also plays important roles in the central nervous system and other peripheral organs, such as improving schizophrenia, autism - related psychiatric and psy-chological symptoms. Oxytocin exhibits its physiological func-tions by binding to its receptor (oxytocin receptor,OTR). Cur-
rently researchers are manipulating OT system by developing new OTR ligand ( agonists and antagonists ) , hoping to prevent and treat OTR related diseases. This paper reviews the latest devel-opment of OTR agonists, antagonists and its physiological roles in central nerve system and peripheral organs.

Objective To investigate the effect of ulinastatin (UTI) on the expression of brainderived neurotrophic factor ( BDNF ) and remyelination in mice with experimental autoimmune encephalomyelitis ( EAE).Methods Twenty-four C57BL/6 mice were randomly divided into UTI group (U),normal saline treated group (S) and normal control group (N,n = 8,respectively).Demyelinations in the spinal cord were observed by solochrome cyanin staining.The expression of BDNF,myelin basic protein (MBP),and 2',3 '-cyclic nucleotide 3'-phosphodiesterase (CNP) in brain tissue of each group were evaluated by Western blot.Results Average clinical scores in group U at the 12,13,14,22,23,31,33,34 and 35 days were 0,0.25,0.38,0.63,0.63,0.40,0.40,0.40 and 0.40 respectively.They were significantly lower than group S at the same time ( U= 16.00,15.00,14.50,7.50,0.00,14.50,14.50,12.00 and 14.50,all P ＜0.05).Solochrome cyanin staining showed that demyelination of spinal cord in group U was also significantly improved than group S.Expressions of BDNF ( 1.96 ± 0.29),MBP (2.67 ± 0.48 ) and CNP ( 1.75 ± 0.20) in group U were all significantly higher than group S ( There were 0.80 ± 0.15,1.36 ± 0.38 and 1.06 ± 0.18 respectively,all P ＜ 0.05).Conclusions UTI has protective effect on EAE.The possible mechanism is that it could promote remyelination,and protect oligodendrocytes and neurons in EAE model by increasing BDNF expression in brain.

Objective In order to research the effect of tyrosine kinase inhibitor in combination with radiotherapy on the inhibi‐tion of breast cancer cells and breast cancer bearing nude mice .Methods Methyl thiazolyl tetrazolium (MTT) assay was used to e‐valuate the inhibition of different concentrations of TKI on breast cancer cells ,the breast cancer cells was divided into three groups :the TKI treatment group ,the cells in the control group (no the TKI processing) and the control group (non‐TKI and X‐ray irradia‐tion group) .The sensitivity of the cells in each group to X‐ray was compared by colony formation assay .MCF7 cells were xenograf‐ted in athymic nude mice to establish the animal model ,which was used to evaluate the effect of anti‐cancer .Results Colony form‐ing test showed that the separated use of any concentrations of the TKI inhibitor could inhibit the breast cells ,and the cell viability was significantly reduced;TKI combined with X‐ray irradiation could significantly increase the sensitivity of breast cancer cells to radiation ,and the difference was statistically significant(P<0 .05) .Compared to TKI inhibitor or X‐ray irradiation alone ,the combi‐nation of TKI inhibitor with X‐ray irradiation could inhibit the growth of tumor effectively .Conclusion The TKI inhibitor in com‐bination with radiotherapy can effectively inhibit the growth of breast cancer cells ,which provides a new theoretical basis for the im‐plementation of the clinical breast cancer radio sensitization .

Objectives To summarize the clinical feature of severe adenovirus pneumonia (SAP) in children and further to improve prognosis and clinical diagnosis of SAP. Methods The clinical data of 213 children with SAP from June 2009 to June 2011 were retrospectively analyzed. Results Among 213 patients, 155 (72.8%) children were aged 6 months to 2 years, with a males to females ratio of 2.7∶1. The onset of 158 patients (74.2%) was in winter and spring. All patients had fever, 172 (80.8%) with high temperature of 39.1℃-41℃, 161 (75.6%) with a fever lasting more than 2 weeks. Two hundred and ifve (96.2%) patients had cough in the early stage, 120 (56.3%) with wheeze, 139 (65.3%) with moist rales and wheezing in the lung. Imaging ifndings in the preliminary stage of SAP showed that 63 patients (92.6%) had pulmonary interstitial changes;in critical stage, 80 patients (54.4%) had segmental consolidation and 33 (22.4%) with pleural effusion, 25 (17.0%) with pleuritis;in recovery phase, 50 patients (68.5%) showed absorption in segmental area of consolidation. All cases had complications, 175 (82.2%) with respiratory failure, including 10 (4.7%) with ARDS;among extrapulmonary complications, diseases of cardiovascular system (64.3%) and alimen-tary system (44.1%) were the most common ones, and the occurrence of myocarditis and diarrheal disease were the highest. Age, ARDS and more than two kinds of complications had adverse impact on the outcomes, and the difference was signiifcant (P<0.05). Conclusions SAP is a severe pneumonia with long duration of high fever, severe clinical manifestations with more complications. When SAP is suspected, it is recommended to complete etiological and chest radiographic examination for early diagnosis and treatment.

Objective To observe the clinical effect and complications of intravenous immunoglobulin(IVIG)in the treatment of severe adenovirus pneumonia(SAP)in children. Methods Clinical data of 210 hospitalized children with SAP from June 2009 to June 2011 were retrospectively analyzed. Patients were divided into IVIG group (109 cases) and control group (101 cases) to compare the therapeutic effects, duration of fever, length of stay in hospital, duration of mechanical ventila-tion, and complications between the two groups. Results There was no difference in the severity of illness on admission and un-derlying diseases between the two groups. Both groups were given antiviral, antibacterial and comprehensive supporting thera-py, and in the IVIG group IVIG 250-400mg/(kg.d) were administered for 3-5 d. The mean hospital stay and fever time of the IVIG group were significantly shortened comparing to that of the control group, and the time of mechanical ventilation on the IVIG group is less than that of the non-IVIG group. Incidence rate of pleural effusion, atelectas is, myocarditis and toxic enceph-alopathy in the IVIG group is lower than the control group, and the cure rateand effective therapy of the IVIG group is higher than control group, all of the difference was statistically significant (P<0.05). No adverse drug reaction was observed. Conclu-sions IVIG is safe and effective in the treatment of SAP in children.

JNK is a key protein in the third stages of MAPK pro-tein kinase activation cascade,and is located in the key node of multiple signal transduction network.It plays a pivotal role in the cell proliferation,differentiation,apoptosis and some other important cell biological processes.Therefore it acts as an im-portant factor in regulating the development of some major human diseases,such as cancer.But the functional diversity and com-plexity of three JNK isoforms in different cell types make it diffi-
cult to develop anticancer drugs with JNK as a treatment target. In this review,we summarized the apoptotic signaling network of JNK and the regulation functions of JNK in cell apoptosis and proliferation.We also discuss the different functions of 3 JNK isoforms in human cancer.

G protein-coupled receptors (GPCRs) are the largest cell surface receptor family, which mediates activities of almost all known cellular response to ligands, including hormones release, neurotransmitters and sensory input.GPCRs can promote development and progression of gastric cancer, colorectal cancer, lung cancer and breast cancer and other tumors.Tyrosine kinase receptors (RTKs) are another important family of membrane receptors, which can regulate cell proliferation, differentiation, migration and survival.Overexpression of RTKs has been found in many cancer cells.Therefore, GPCRs and RTKs are equally important in the clinical treatment of cancer therapeutic.However, GPCRs and RTKs are not independent, and they can use common signal transduction.The present study show that crosstalk between GPCRs and RTKs can facilitate migration of lung epithelial cells, increasing survival of nerve cells and promoting tumor occurrence and development.This article mainly focuses on crosstalk between GPCRs and RTKs and their roles in tumorigenesis and oncotherapy.
