Objective To investigate current status of narcotic analgesic use in patients with cancer pain in our hospital, in order to promote the rationalization of prescribing narcotic drugs and the rational use of analgesics. Methods A total of 400 narcotic prescriptions ( 100 of outpatients and 300 of inpatients ) in Tongji hospital were randomly selected from March to May in 2014.Basic index and consumption of anesthetic drugs, money consumption distribution on different tumor types, and unreasonable prescription were analyzed. Results The overall prevalence of irrational prescriptions was 11. 00%, with 13.00% from inpatient and 10. 33% from outpatient, respectively. Reasons for irrational prescriptions mainly included vague instructions on dosage and administration, incomplete clinical diagnosis, lack of pharmacist check and inappropriate dosage. In the basic indexes, proportions of reasonable prescription and drugs within the national formulary were higher in the inpatient than in the outpatient service.The average money consumption of outpatient prescription was significantly higher than that of inpatient prescription.Most types of diagnosis were lung cancer in outpatient and inpatient departments, and total cost of lung cancer drugs was the highest.Morphine hydrochloride of outpatient had the highest average consumption, followed by codeine phosphate of the outpatient and the inpatient, and oxycodone hydrochloride controlled-release tablets cost more in inpatient. Conclusion The narcotic analgesic used in our hospital is basically rational. Most doctors prescribe according to the guidelines, but standardized training of prescription for cancer patients with pain medication needs to be strengthened, and supervision of narcotic analgesic medication should be enhanced.

BACKGROUND: The quality of chest compressions can be significantly improved after training of rescuers according to the latest national guidelines of China. However, rescuers may be unable to maintain adequate compression or ventilation throughout a response of average emergency medical services because of increased rescuer fatigue. In the present study, we evaluated the performance of cardiopulmonary resuscitation (CPR) in training of military medical university students during a prolonged basic life support (BLS). METHODS: A 3-hour BLS training was given to 120 military medical university students. Six months after the training, 115 students performed single rescuer BLS on a manikin for 8 minutes. The qualities of chest compressions as well as ventilations were assessed. RESULTS: The average compression depth and rate were 53.7±5.3 mm and 135.1±15.7 compressions per minute respectively. The proportion of chest compressions with appropriate depth was 71.7％±28.4％. The average ventilation volume was 847.2±260.4 mL and the proportion of students with adequate ventilation was 63.5％. Compared with male students, significantly lower compression depth (46.7±4.8 vs. 54.6±4.8 mm,P<0.001) and adequate compression rate (35.5％±26.5％ vs. 76.1％±25.1％,P<0.001) were observed in female students. CONCLUSIONS: CPR was found to be related to gender, body weight, and body mass index of students in this study. The quality of chest compressions was well maintained in male students during 8 minutes of conventional CPR but declined rapidly in female students after 2 minutes according to the latest national guidelines. Physical fitness and rescuer fatigue did not affect the quality of ventilation.

Objective To investigate the ability of nurse-patient communication and Self-efficacy between baccalaureate and associate nursing students, and provide instruction for fostering the nurses' positive ability of nurse-patient communication and Self-efficacy. Methods Thirty baccalaureate nursing students from Grade 2005 and 30 associate nursing students from Grade 2006 in the nursing school of Mudanjiang Medical College were selected by random sampling and were investigated with the ability nurse-patient communication Scale by XuYaHong and General Self-Efficacy Scale by Ralf scchwarzer. Results The total level of nursepatient communication ability was medium or above that. There was significantly different in the ability of nursepatient communication between nurses with different educational level in terms of the total scores of nurse-patient communication, scores of coffering information and understanding patients, those in baccalaureate nursing students were higher than those in associate nursing students. Conclusions The clinicle teacher must take implemation to cultivate the ability of nurse-patient communication during the clinical practice. The result suggests that teachers should build the students' positive self-efficacy to improve their nurse-patient communication, ability.

OBJECTIVETo study the oncogene transcriptor c-myc, stimulatory protein 1 (SP1) expression in ameloblastoma (AB) and their relation with telomerase reverse transcripase (hTERT), and to investigate the clinical biological characteristics of AB.

METHODSThe expression was observed in AB by in situ hybridization and SP method.

RESULTSThe positive rates of c-myc mRNA, hTERT mRNA and SP1 protein were 81.5% (44/54), 94.4% (51/54) and 83.3% (45/54), respectively. Their positive rates increased as AB recurred and transformed malignantly. A strong correlation was found between hTERT and c-myc, hTERT and SP1 (rs = 0.853, P < 0.001; rs = 0.900, P < 0.001).

CONCLUSIONActivity of telomerase plays an important role in the tumorigenesis development of AB. Increasing of hTERT expression may be related to c-myc and SP1. The expression of these three parameters has a significant correlation with the clinical biological characteristics of AB.

Hypophosphatasia is a rare inborn disease of metabolism. This paper reviewed its pathogenesis, forms, clinical manifestations, differential diagnosis,treatment and prognosis. Here a case of neonatal hypophosphatasia is reported. This baby was female (30 minutes old). Prenatal ultrasound showed disproportionate biparietal diameter and long bones of limbs in the baby. After birth, she presented with obvious craniomalacia, respiratory distress and cyanosis. Serum alkaline phosphatase level was significantly reduced. Both X-ray and autopsy showed extremely insufficient skeletal mineralization. Four days later she died of respiratory failure.

A sensitive high performance liquid chromatography-electrospray ionization-mass spectrometry (HPLC-ESI-MS) method was established for the determination of eplerenone (EP) in human plasma. The plasma samples of EP were extracted with ethyl acetate and separated by HPLC on a reversed phase C18 column with a mobile phase of 10 mmol x L(-1) ammonium acetate water solution-methanol (30 : 70, v/v). EP was determined with electrospray ionization-mass spectrometry (ESI-MS) in the selected ion monitoring (SIM) mode. The calibration curves were linear over the range of 2-4 000 ng x mL(-1) for EP. The lower limit of quantification was 2 ng x mL(-1). The method has been successfully applied in the pharmacokinetic study of the EP tablets. The main pharmacokinetic parameters of EP after oral administration of 25 mg, 50 mg, 100 mg were as follows, t1/2: (4.9 +/- 2.1), (4.7 +/- 1.5), (5.9 +/- 1.2) h; AUC(0-infinity): (4 402 +/- 1 735), (8 150 +/- 2 509), (13 783 +/- 4 102) microg x h x L(-1); and MRT: (6.2 +/- 2.1), (6.6 +/- 1.3), and (7.2 +/- 1.6) h. Parameters of EP after oral administration of multiple doses of 50 mg were as follows, t1/2: (6.1 +/- 1.7) h; AUC(ss): (10 071 +/- 4220) microg x h x L(-1); MRT: (8.1 +/- 2.3) h; and DF: (3.2 +/- 1.0).
