Objective:To explore the etiology and drug resistance of the ICU ventilator-associated pneumonia.Methods: One hundred cases of patients with ventilator-associated pneumonia received in our ICU room were selected; the pathologic examination results were retrospectively analyzed.Results: One hundred and thirty five bacteria were isolated from 100 cases of patients with ventilator-associated pneumonia, including 95 cases of Gram-negative bacilli(70.5%), 34 cases of Gram-positive cocci(25.1%) and 6 cases of fungi(4.4%); The resistance rates of Pseudomonas aeruginosa and Klebsiella pneumoniae for cefazolin, gentamicin, levofloxacin, and trimethoprim-sulfamethoxazole were high; The resistance rate of Staphylococcus aureus for ceftazidime, ceftriaxone, cefepime, cefazolin, gentamicin, amikacin, ciprofloxacin, levofloxacin, cefoperazone/sulbactam and piperacillin were high.Conclusion: ICU ventilator-associated pneumonia pathogen was mainly Gram-negative bacteria, and showed multidrug resistance, imipenem and cefoperazone/sulbactam for most pathogens had better efficacy and worthy of clinical application.

Objective:To study the expression of p73? and its clinical significance in breast carcinoma.Methods:The expression of p73? was detected by immunohistochemistry in 41 breast carcinoma tissues,13 benign breast tumor tissues and 8 normal breast tissues.Results:The positive expression of p73? was found in 20/41(48.8%) of breast carcinoma tissues,1/13(7.7%)of benign breast tumor tissues,0/8(0)of normal breast tissues.The positive expression rate of p73? in breast carcinoma tissues was significantly higher than that in benign breast tumor tissues or normal breast tissues(P

This article summarized some in vitro models of drug absorption,whose shortcomings and virtues were compared in order to be convenient for researchers to know and select optimal model.

Objective:To find a better way to protect the security and interests of vulnerable groups by exploring the problem of protecting the vulnerable groups in drug clinical trial from the perspectives of ethics committees,organization and researchers.Methods:According to the relevant literature and the actual situation of the hospital,this paper analyzed the security issues of vulnerable groups comprehensively.Results:Only the ethics committees,organization and researchers work together,can it protect the security and interests of vulnerable groups to the greatest extents.Conclusion:Further research on the security of vulnerable groups not only promotes the development of human health,but also plays a decisive role in improving the protection of subjects in drug clinical trial.

Postprandial hyperglycemia is a risk factor for atherosclerosis and cerebro-vascular diseases. This article reviews the mechanisms of cerebrovascular diseases caused by postprandial hyperglycemia from aspects of postprandial hyperglycemia participating in the pathophysiological mechanisms of atherosclerosis, and the relations between postprandial hyperglycemia and cerebrovascular diseases.

used at the primary-care settings in China to assess asthma control.

Type 1 diabetes mellitus (TlDM) is an autoimmune disease characterized by the destruction of pancreatic β cells, which sequentially leading to the reduction of insulin secretion. Numerous susceptibilities, including genetic and environmental factors, may be involved in triggering the T1DM. The ideal therapy for T1DM should focus on both preventing the immune system from attacking β cells, and also the stimulation of β cell neogenesis. In vitro and in vivo studies both demonstrated that GLP-1 analogues were able to promote the synthesis and secretion of insulin, stimulate neogenesis of β cells, increase β cells replication, and reduce β cell apoptosis. Hence, GLP-1 analogues have been shown to be potential treatment for T1DM. This work reviewed recent publications regarding to GLP-1 application in TlDM and pancreatic islet transplantations and prospected the future research directions.

Mantle cell lymphoma (MCL), is a disease with high heterogeneity, which is insensitivity to the chemotherapy and presents poor prognosis. Appearance of the Bruton tyrosine kinase (BTK) targeted inhibitors, such as ibrutinib, provides novel treatment strategy for MCL. This review focused on the latest achievements of BTK inhibitors in MCL treatment.

At present,conventional whole brain radiotherapy is the standard treatment for brain metastases and prophylactic cranial irradiation,and it can improve patients' clinical symptoms and survival.However,whole brain radiotherapy may induce cognitive function impairment and affect patients' long-term quality of life.The newest radiotherapy technology can protect the hippocampal gyrus during whole brain radiotherapy and then protect cognitive function and improve quality of life.This article reviews the methods and clinical value of hippocampal gyrus protection in whole brain radiotherapy,as well as related advances.
