The results of chemotherapy in the treatment of soft tissue sarcoma seem to have reached a plateau.Targeted therapy is the key to improve curative efficacy.Although there are many kinds of targeted therapy drugs of the first generation,only several targeted drugs that target angiogenesis and the epidermal growth factor receptor have showed survival benefits in prospective,randomized,phase Ⅲ clinical trials.Recent data suggest that multitargeted inhibitors might have greater activity owing to their ability to simultaneously block several key signaling pathways.Preliminary results of such agents in clinical trials show that they have a well tolerated toxicity profile,and might have a promising vahle in the treatment of soft tissue sarcoma.

Congenital heart disease (CHD) is the most common heart disease in children, which does great harm to children's health. Tetralogy of Fallot(TOF) is the primary form of cyanosis CHD, with the incidence rate of 10% ～ 15% in CHD. Tissue Doppler lmaging(TDI) ,a new type of Doppler echocardiography, is a noninvasive and a promising method in determination of right and left ventricle constriction and dilatation function quantificationally, which will improve the development of acquainting with heart disease and guid the clinical treatment of CHD. This review is to summarize the status quo of TDI in congenital heart disease especially in TOF.

Based on the theory of cancer stem cells (CSCs),people have been searching for the treatments of malignant cancers.Gastric cancer side population cells (SP) have the characteristics of CSCs.Searching for the molecular targeted therapy strategy of gastric cancer which embarks from the gastric cancer SP and is based on the theory of CSCs provides a new direction for the treatment,early diagnosis,therapeutic effect and prognosis of gastric cancer.

Objective:To observe characteristics of TCM syndrome types in the patient of cerebral infarction,and cerebral infarction with respiratory disorder at sleep.Methods:90 in-patients of cerebral infarction were monitored by polychannel sommocinematogram (PSG)within 72 hours of admission,which were used as diagnosis of respiratory disturbance at sleep,and all of the patients with apoplexy involving the channels and collaterals were divided into 3 types,collaterals hollow and pathogenic wind attacking the interior;Yin-deficiency of the liver and kidney,and wind-Yang stirring upper,hot phlegm and excess of Fu-organs,and wind- phlegm stirring the upper.Results:The patient had sleep structure disorder,with large change of blood pressure and lower heart variety,and decrease of degree of blood oxygen saturation.The apnea indexes were the highest for the patient with phlegm-heat hollow-organ excess,wind-phlegm stirring the upper,and baic normal for collateral hollow and pathogenic wind attacking the interior.Conclusion:There is close relation of cerebral infarction,especially in the patient of hot phlegm and excess of Fu-organ, with respiratory disorder at sleep.

The peptidyl prolyl cis/trans isomerase Pin1 specifically binds phosphorylated Ser/Thr-Pro protein motifs and catalyzes the cis/trans isomerization of the peptide bond,changes the conformation and influences the stability and activity of the substrates.To date,a subset of proteins has been identified as substrates for Pin1.Pin1 interacts with its substrates and plays crucial roles in cell cycle,neural pathology and immune response.Accumulating studies have revealed that Pin1 isomerase activity is regulated by its post-translational modifications,including phosphorylation and oxidation.Over-expression or regulative imbalance of Pin1 plays an important role in the pathogenesis and therapeutics of human diseases such as cancer and AD.

Objective:To establish a specialized detection method for quinolone drugs illegally added in health foods and Chinese traditional patent medicines. Methods: LC-MS/MS was used to simultaneously screen pipemidic acid, norfloxacin, ciprofloxacin, lomefloxacin, enoxacin, fleroxacin, pefloxacin, sparfloxacin, gatifloxacin and ofloxacinan in health foods and Chinese traditional patent medicines. Qualitative and quantitative analysis and methodology validation were studied as well. Results:Under the conditions of the analysis method, the 10 quinolone drugs added illegally obtained a good separation on a chromatographic column. With the two grade mass spectrum for the qualitative analysis and the peak area of multiple reactions monitoring mode for the quantitative calculation, the method was specific and sophisticated. The recovery and linear relationship met the demand of screening. Conclusion:The method is simple and accurate in the detection of quinolone drugs in health food and Chinese traditional patent medicines.

MAPKKK (MEKK1 or ASK1)/MAPKK (SEK1 or MKK7)/JNK signal cascade is an important pathway which mediates apoptosis. MAPK phosphotase can deactivate JNK by dephosphorylation of JNK.The interaction between JNK and c-Jun can also be negatively regulated by NO through S-nitrosylation. SGK1 or Akt can result in deactivation of SEK1 through its phosphorylation at the Ser78 site.The c-FLIPL can block this cascade through binding with MKK7.GST Mu1-1 interferes and suppresses MEKK1-mediated apoptosis. GST Pi 1-1 and TRX have a dose-dependent inhibitory effect on ASK1 through forming protein complex. The deactivation of JNK can enhance drug resistance of tumor cells and counteract the injury from a wide variety of stimulus. Here,how these proteins induce deactivation of the pathway and mediate anti-apoptosis has been discussed.

Exendin-4,a peptide analogue of glucagon-like peptide-1(GLP-1),is presently in clinical trials as a therapy for type 2 diabetes mellitus.Exendin-4 selectively acts on GLP-1 receptors,which are coupled to the cAMP nucleotide second messenger pathway to enhance the survival and plasticity of neurons in the brain.Exendin-4 has potent effects on homeostasis of Ca2+,on multiple targets to block apoptotic signaling pathways,and on neuronal proliferation and differentiation.It has also been demonstrated to possess properties against oxidative stress and excitotoxicity.In this review the functions of exendin-4 on central nerve system and the potentia therapeutic effects on neurodegenerative diseases will be involved.
