BACKGROUND:Acute myeloid leukemia after liver transplantation is a rare complication with high mortality. OBJECTIVE:To study the clinical features of acute myeloid leukemia after liver transplantation. METHODS:One case of acute promyelocytic leukemia after liver transplantation was reported, and literatures were reviewed. RESULTS AND CONCLUSION:Case presentation was post-odontectomy bleeding with associative abnormal coagulation test at 85 months after liver transplantation. Routine blood test, bone marrow test and chromosome analysis and examination diagnosed as acute promyelocytic leukemia and promyelocytic leukemia/RARαpositive chimeric gene, and clearly diagnosed as acute promyelocytic leukemia combined with disseminated intravascular coagulation. The patient received fresh frozen plasma transfusion to correct the abnormal coagulation, and then received induction chemotherapy with retinoic acid, arsenic trioxide and daunorubicin to obtain bone marrow complete remission. The patient was treated with daunorubicin combined with cytarabine and mitoxantrone combined with cytarabine regimens after remission induction to consolidate the chemotherapy for two courses of treatment, and then subsequently subjected to arsenous acid chemotherapy, and the bone marrow was sustained for remission. During chemotherapy, the dose and type of immunosuppressive agents were adjusted, and the patient had stable liver function without serious infection or complications. The results indicate that acute myeloid leukemia is common and often occurs after liver transplantation. When the patient displays hematological abnormality, acute promyelocytic leukemia should be considered. Early diagnosis and treatment can reduce the mortality.

Objective To understand the level of neonatal pain knowledge and attitudes of neonatal and obstetric department nurses, in order to supply the clinical basis for neonatal pain management. Methods Self-designed questionnaires to fill out on-site were distributed to 107 neonatal and obstetric department nurses (of which 40 were from neonatal department, 67 from obstetric department) for neonatal pain knowledge and attitudes. Results About question of neonatal pain, the average percentage of correct answers in the neonatal group was 75.5%, higher than 66.3% of the obstetric group, in the neonatal group, correct rate of seven questions was more than 80%,while in the obstetric group the correct rate of only one question was more than 80%, and 5 questions correct response rate was significantly lower than that of the neonatal group, the difference was significant. All nursing staff considered it essential or necessary to carry out the nursing knowledge of pain-related training. 95.0%(38/40) of neonatal nurses believed that they could properly assess the extent of neonatal pain, but only 83.6% (56/67) for the obstetric group, the difference between the two groups was significant. 97.5% (39/40) of neonatal nurses believed that they could make the right judgments on neonatal crying, and only 85.1%( 57/67) in the obstetric nurses, the difference between the two groups was significant.Conclusions Neonatal pain has gradually been recognized and paid attention to by the clinical front-line medical staff, they believe that it is necessary to receive training on neonatal pain, knowledge of neonatal pain of neonatal nurses is better than obstetric nurses.

OBJECTIVE: To seek pathological features, diagnosis, treatment, prognosis of Epithelial-myoepithelial carcinoma arising in the nasal cavity. METHOD: One case of Epithelial-myoepithelial carcinoma arising in the nasal cavity was analyzed retrospectively and studied with immunohistochemical Staining and light microscopy, as well as review of the literature. RESULT: The clinical feature of epithelial-myoepithelial carcinoma in the nasal cavity was atypical and diagnosis relied on pathologic features. Epithelial-myoepithelial carcinoma consisted of myoepithelial and epithelial cells. Immunohistochemical staining demonstrated that cytokeratin P, cytokeratin L, S-100 protein, a-smooth muscle actin expressed positively. CONCLUSION Epithelial-myoepithelial carcinoma in the nasal cavity is a rare neoplasm. Wide surgical excision with a clear margin is the main therapy,and these tumors have the potential for metastasis and recurrence.

The three-dimensional model of the silicone artificial disc was converted into a finite element model through software ANSYS12.0. RESULTS AND CONCLUSION:Through CT scanning, digital image processing and computer-aided design, the three-dimensional model of the lumbar motion segment and the finite element model of artificial disc replacement were successful y established. The finite element model contained 691 085 units and 1 008 913 nodes which could be applied constraint and load and could be used for spinal biomechanics and the further research of the new artificial intervertebral disc.

Objective To investigate the influencing factors of pain and the changes of vital signs in newborn infants. Methods Forty two newborn infants were rated by the behavioral scale of acute pain in newborn infants. The scores of pain were compared among infants with different gender,gestational age,birth weight,birth age,type of puncture and whether by vaginal birth or not. At the same time,the respiration rate,heart rate,blood pressure and oxygen saturation (SO2)were dynami-cally recorded by the multi-function monitor in the process of puncture. Results The average score of pain was 7.6. There was no significant difference among newborn infants with different gender,gestational age,birth weight and type of puncture(P> 0.05),while significant differences among infants with different birth age and whether by vaginal birth or not (P=0.015 and 0.043 respectively). In the process of puncture,the SO2 was significantly decreased,while the respiration rate,heart rate,sys-tolic and diastolic blood pressure were significantly increased. Conclusions Pain is prevalent in newborn infants and accom-panied by obvious changes of vital signs. The means of childbirth and birth age have significant influence on the neonatal pain. It is suggested to pay close attention to the neonatal pain and take effective interventions.

Objective To investigate the influences of pain on early neonatal neurobehavioral development Methods 65 newborn infants admitted to the Neonatal Intensive Care Unit( NICU )of our hospital from October,2009 to March,2010 were randomly chosen as the objects of this study.In light of Neonatal Behavioral Neurological Assessment( NBNA) revised by Professor Bao Xiulan,examinations were carried out before and after pain stimulation,and a statistical analysis of the results of the examinations was conducted.Results The total scores of NBNA before and after the pain stimulation were (36.49±1.73) vs.(34.80±1.79) respectively,demonstrating a significant difference.Specifically,after the pain stimulation,the scores of behavioral ability and active muscle tension decreased,with a very significant difference.However,there was no significant difference in terms of the scores of passive muscle tone,primitive reflexes and common reactions.Conclusions Neonatal pain exerts influences on early neurobehavioral development,particularly on behavioral ability and active muscle tension.The training of neonatal health care professionals in the management of and the intervention in neonatal pain should be strengthened in order to decrease the adverse effects of pain on neonates.
