Conclusions The clinical nursing pathway for artificial abortion operation may improve the degree of satisfaction- and the status of patients' awareness about contraception and artificial abortion operation, and decline the proportion of missing item of operation note, it ensures high nursing quality and safety surgery, which is worthy of popularizing.

Inquisition language,as the information carrier on observing and describing disease status,makes it possible for patients to communicate well with doctors to acknowledge disease information.In order to make inquisition language possess specific properties of medical conversation,doctors need to master language skills in procedural inquisition,proper listening and responding to inquisition,distinguishing inquisition,transitional inquisition and secret-involved inquisition.Upholding inquisition language with courtesy,comfort,being explanatory,encouraging,and protecting is the basic requirement of clinical ethics.

Objective To retrospectively overview the malaria death cases reported in Henan Province and analyze the cause of death. Methods The data including basic information,epidemiological survey and medical records of malaria death cases in Henan Province from 2010 to 2015 were collected and analyzed. Results In the six years,a total of 14 malaria pa?tients were dead. All the death patients were adult males and imported from Africa. They had definite histories of living in malaria?epidemic areas and the symptoms of fever. Twelve patients were diagnosed as malaria after at least twice diagnoses. The average time from symptom appearing to correct diagnosis was 6.5 d. The causes of deaths were misdiagnosis and delayed treatment. Con?clusions The major reasons of malaria death cases in Henan Province are the failure of correct diagnosis and prompt treatment. Health education of malaria prevention and diagnosis and treatment training of malaria should be strengthened in order to im?prove the public awareness and the diagnosis ability of clinical doctors for malaria,which can prevent the death of imported ma?laria cases.

Objective To observe the effects of expressions of neurocyte adhesion molecule (NCAM) and growth associated protein-43 (GAP-43) in neurological function recovery following cerebral ischemia-reperfusion in rats. Methods The model of focal ischemia-reperfusion in SD rat was induced by intraluminal middle cerebral artery (MCA) occlusion with a nylon monofilament suture. In situ hybridization (ISH) was performed to examine the expression of NCAM mRNA and GAP-43 mRNA at 2,12 h and 1,2,3,7,14 d after reperfusion and in sham-operated controls. Results There was no functional deficit and little expression of NCAM mRNA and GAP-43 mRNA in brain cells in rats of the sham-operated group. In the experimental group, NCAM mRNA expression was observed after reperfusion for 2 h in cortex and striatum and peaked at 12 h and was still higher at 7 d. The neurological function improved at reperfusion of 3 d~14 d compared to reperfusion 2 h. In the ischemic cortex and striatum, GAP-43 mRNA expression demonstrated "double-peak" at 12 h and 2 d after reperfusion, then decreased gradually to the level of sham-operated group at 14 d. Conclusion The increasing NCAM expression might be an important factor of the neural reparation and GAP-43 might enhance the neurological functional recovery with ischemic brain injury in rat.
