OBJECTIVE:TO summarize the newest clinical application of permanent cardiac pacemaker, and introduce the relationship between the therapy efficacy and mechanism.DATA SOURCES: Related papers were searched in Pubmed from January 2000 to December 2006 with the terms of "pacemaker,application",and the language of paper was limited to English,at the same time,related papers were searched in WangFang Database with the same terms and the language of paper was limited to Chinese.STUDY SELECTION:The papers relevant to the newest large-scale clinical trial about the cardiac pacemaker were primarily collected.Exclusion criteria:repetitive studies.DATA EXTRACTION:A total of 203 pieces of papers related to the newest clinical application of cardiac pacemaker were collected,among which,30 pieces accorded with the inclusion criteria.DATA SYNTHESIS:The pacemaker can simulate the normal myocardium cell's function pacing and conducting the rhythm. Consequently it can substitute the abnormal myocardium cell to ensure the sequence and completeness of the cardiac pacing and conducting system,the natural electrophysiological activity,and the efficiency of the cardiac ejection and blood supply.The clinical application is not only for single bradycardia, but also for cardiac electric failure, cardiac electric turbulence,and some heart diseases without cardiac electric abnormity.With pacemaker miniaturization,digital signal processing, improved diagnostics and endocardial electrograms, modern pacemakers are able to offer a sophisticated therapeutic and diagnostic platform for the patients with refractory symptoms.CONCLUSION:The pacemaker can simulate the normal myocardium cell's function pacing and conducting the rhythm.It therapy for congenital heart disease.

Molecular targeted therapy (MTT) refers to a new therapy designed to interfere with a specific molecular target or signaling pathway that may have a significant influence in tumor growth or progression. MTT can inhibit cell proliferation and induce apoptosis by specific interventions in the signaling pathways of tumor cells. MTT exhibits potential as an effective treatment against cancer. This approach can improve the ability to kill cancer cells and reduce damage to normal tissues. MTT has gradually been used clinically in treating cancer and shown advantages over traditional methods. This paper reviews research progress in this targeted therapy to treat gynecological cancer.

Objective To explore the effect of emergency corpus luteum cystectomy for the prevention of persistent ectopic pregnancy(PEP).Methods The clinical data of 68 patients with ectopie pregnancy in emergency conservative operation were analyzed retrospectively.All patients were divided into the observation group(treated with corpus luteum cystectomy,40 cases) and control group (without corpus luteum cystectomy,28 cases).The declining of β-HCG,incidence rate of PEP were compared between the two groups.Results The incidence rate of PEP of the observation group was 0,which was obviously lower than that of the control group(10.7％) (x2 =4.47,P ＜ 0.05).Conclusion The emergency corpus luteum cystectomy can effectively prevent PEP and the operation is simple and convenient.

Recently,the Society of Critical Care Medicine and the European Society of Intensive Care Medicine sponsored a 19-member Task Force to update the definitions of sepsis and septic shock at the forty-fifth Critical Care Medicine Annual Meeting in February 2016.Owing to an increased understanding of the harmful systemic response to infection,members of the multidisciplinary task force proposed that sepsis now be defined as life threatening organ dysfunction caused by a dysregulated host response to infection.To standardize the assessment of organ dysfunction,the Task Force members propose that provider use the sequential organ failure assessment(SOFA) score and quick SOFA (qSOFA).Although the systemic inflammatory response syndrome(SIRS) standard has high sensitivity and low specificity,the mortality of sepsis in the world has decreased significantly in the past 20 years.With the gradual realization of sepsis 3.0,will SIRS really be completely out of the stage of history? The SOFA and qSOFA criteria is not suitable for children.The author thinks that SIRS standard still has its practical application value.We need further studies on how to improve the sensitivity and specificity of sepsis diagnosis at the same.We should continue to validate sepsis 3.0.
