Bone remodeling is an ordered process of coupling of bone resorption and bone formation. Cytokines secreted by different bone cells and membrane molecules expressed by bone cells are involved in regulation of coupling of bone resorption and bone formation. To reveal the mechanism of bone coupling is of great significance in the study and diagnosis of osteoporosis and other metabolic bone diseases. In the present review, we summarize the progression of mechanisms by which cytokines and the related membrane molecules are regulating the coupling of bone resorption and bone formation.

Objective To investigate the relation between omentin and coronary artery disease.Methods Eighty-eight eases were divided into 2 groups, coronary artery disease group (56 cases, includingacute coronary syndrome 28 cases and stable angina 28 cases), and non-coronary artery disease group (32cases). The plasma omentin levels were assayed by ELISA, and height, weight, blood pressure, totalcholesterol high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C),lriglyeeride (TG), high-sensitivity C-reactive protein were detected. Results The plasma omentin level incoronary artery disease group [(33.4 + 6.4) μg/L] was lower than that in non-coronary artery disease group [(51.8 + 7.7) μg/L](P= 0.034). Logistic analysis showed that the decline of omentin was an independent risk factor of coronary artery disease (P=0.012). Conclusions The decline of omentin is an independent risk factor of coronary artery disease. The plasma omentin may contribute, in part, to the pathogenesis of coronary artery disease.

Atomoxetine as a nonstimulant medicine was approved by the Chinese Food an Drug Administration and provide a new selection of treatment drugs for attention deficit hyperactivity disorder (ADHD). Tomoxetine is a noradrenaline transmitter reuptake inhibitor which can selectively inhibit synapsis noradrenaline transport protein, strengthen noradrenaline's resupination effect, and increase noradrenaline's activity released by synaptic cleft to improve the symptoms of the ADHD patients. Compared with methylphenidate, atomoxetine does not affect the concentration of the neurotransmitter dopamine and does not induce or increase the Tourettes' syndrome, therefore atomoxetine is more suitable to treat ADHD together with Tourettes syndrome. In this article the treatment of atomoxetine for ADHD, including the indications, dosage as well as adverse reactions and efficacy assessment are reviewed.

Objective To explore the role of CD95 system in chemotherapeutic sensitivity of pancreatic cancer cells, in an attempt to enhance the efficacy of chemotherapy by transfection CD95 gene, and to provide the evidence for the immunological treatment of pancreatic cancer. Methods CD95 gene was transfected into the pancreatic cancer cell line SW1990 by lipofectamine. The transfected cells were selected by G418. CD95 expressions of the transfected cells were detected by Northern blot and Western blot. MTT assay was used to analyze the response of the transfected cells to 5 fluorouracil, adriamycin (ADM), gemcitabine and in combination with anti CD95 monoclonal antibody (mAb). The drug induced apoptosis of transfected cells was measured by flow cytometry. Results The transfected pancreatic cancer cell SW1990 could overexpress CD95 stably. The CD95 mRNA and protein expressions were significantly increased in the transfected cells than in the controls. Anti CD95 mAb could inhibit the growth of the transfected cells. In addition, transfected cells were more sensitive to clinically relevant concentrations of chemotherapeutic drugs than non transfected cells. Anti CD95 mAb addition could enhance the cytotoxic effect of chemotherapeutic drugs. Drug induced apoptosis in ADM treated transfected cells more pronounced than in non transfected cells. Conclusions CD95 transfection could increase the sensitivity of pancreatic cancer cell SW1990 to, and partly reverse the resistance to, chemotherapeutic drugs. The combination of chemotherapeutic drugs with anti CD95 mAb showed a synergistic cytotoxicity to pancreatic cancer cells.

Objective: In order to implement effectively on-scene medical response to a nuclear or radiological emergency, and also keep track of relevant on-scene audio and video information and monitoring data, we have designed and developed a monitoring platform for medical response to nuclear or radiological emergency. Methods:Based on relevant national standards for emergency response and the features of nuclear or radiological emergency, exploiting modern information technology and monitoring equipments, we formulate the design idea, characteristics, functions and framework of the platform. This platform takes treatment centers for nuclear or radiological injuries, designated medical institutions and medical response teams as main users. Results:We have developed the monitoring platform for medical response to nuclear or radiological emergency. Conclusion:Through the application of this platform, we hope to enhance the preparedness and on-scene response capability for nuclear or radiological emergency, and also provide information support for disposal of nuclear or radiological emergency in the future.

Soluble ST2 (sST2) is a decoy receptor of IL-33 in blood.sST2and ST2L (receptor on cell membrane) seem to be markedly induced in mechanically overloaded cardiac myocytes,especially the expression of sST2.A large number of sST2 bind IL-33 thus subtracting IL-33 from the interaction with ST2L,potentially attenuating the cardioprotective effects of IL-33/ST2L pathway.Recently,sST2 has emerged as a novel for heart failure biomarker.Though sST2 was a less robust marker for the diagnosis of heart failure than NT-proBNP,it has been implicated in the prognostication of patients with acute dyspnea,acute or chronic heart failure and myocardial infarction,with particular value for mid-and long-term prognosis.However,further studies are needed in order to better point out the evidence for a routine use of sST2 evaluation in patients suffering from cardiovascular diseases.

Several proteins are involved in the absorption of cholesterol in small intestine.Niemann-Pick C1 like 1 (NPC1L1) mainly mediates the absorption of cholesterol, and acyl-coenzyme A ( CoA)∶cholesterol acyltransferase 2 (ACAT2) catalyzes the free cholesterol absorpted by intestine into cholesterol ester,while unesterified free cholesterol is secreted into intestinal lumen by ATP-binding cassette(ABC) transporters G5/G8(ABCG5/ABCG8).Transcription factor liver X receptor( LXR) plays an important role in the process of intestinal cholesterol absorption.The research progress in NPC1L1,ABCG5/ABCG8,ACAT2 and LXR is reviewed in this article.

Objective To analyze perioperative nursing methods of chest wall tumor removal and chest wall reconstruction. Methods 12 patients with chest wall tumor removal and chest wall revascularization were choosed as the research objects,and which were given prospective nursing intervention combined with high quality nursing intervention. Results 12 patients all cured without one case death occurred, and 4 cases complications. Followed up for 6 to 36 months, no local recurrence of alienation, chest wall deformity and rejection. Conclusions Proactive nursing intervention help to predict perioperative complications. High-quality nursing care including psychological nursing, skin nursing, pain nursing, function training etc, can promote patients recovery.

Graduate medical education, postgraduate medical education and continuing medi-cal education between China and the United States were compared in order to explore a better physi-cian training system of China. The physician training system of the United States has a series of ad-vantages such as strict access system, uniform training standard and closely linked among each stage, etc. We should make clear medical education standards and strengthen the cohesion between each stage, standardize the management mode and perfect the management system and promote regular as-sessment system.
