Objective To investigate nurses′ learning motivation and learning satisfaction with continued education and analyze its influencing factors. Method One hundred and seventy-nine nurses were enrolled in the survey and the general information questionnaire, education participation scale and continuing education learning satisfaction scale were used in the investigation. Results The average score by nursing education participation scale was (3.26 ± 0.59), and that of continuing education learning satisfaction scale was (2.74 ± 0.48). There were statistically significant differences in age, length of employment, professional title, marital status, employment mode between the scores by the two scales (P < 0.01). Conclusions Nurses′ learning motivation and learning satisfaction with continuing education are in the medium level. Pertinent guidance such as bringing continuing education in depth and width is suggested to improve satisfaction and motivations of nurses.

Objective To explore the influencing factors for the purity and viability of primary cultured cortical neurons of rat,and optimize the separating and cultivating conditions of the cortical neurons.Methods The primary cotical neurons were cultured in a serum-free culture system of B27-supplemented neurobasal medium.The differences in purity and viability of primary cultured neurons between embr-yonic rat group and newborn rat [postnatal 24 h and 5 d] group were evaluated by morphology,immunocytochemistry of neuron-specific enolase(NSE) and trypan blue staining.The changes of neurons purity and viability in different trypsin digestion time(0 min,5 min and 15 min) at different environment temperatures(20 ℃ and 30 ℃) were assessed by immunocytochemistry and trypan blue staining.Results The primary cultured neurons from fetal and newborn rats grew well.There was no significant difference in embryonic rat and postnatal 1 d newborn rat group[(91.30?1.03)%,(89.50?1.78)% respectively in purity;and(98.20?0.58)%,(97.10?0.98)% respectively in viability].The neurons from 5-days newborn rat were inferior to that from fetal and 1-day newborn rat in purity and viability[(82.00?1.25)% and(92.87?1.56)% respectively].Shortening operation time and adjusting digestion time according to the environment temperatures could improve neuronal viability:A digestion for 15min at the environment temperature of 20 ℃ or for 5 min at 30 ℃ could acquired cells with higher viability [(98.20?0.58)% and(96.70?0.64)% respectively].Conclusions It is an easy,practical choice to culture priamry cortical neurons from postnatal 1 d newborn rats.Optimizing the separating and cultivating condition(environment temperatures,digest time,et al.) will improve the neurons purity and viability.

Pinellia ternate and Pinellia pedatisecta lectins with biological functions could be obtained through procaryon expression.Their biological similarities and differences were analyzed and further experiments were conducted to discuss the agglutinative activity difference between polymer lectin and metamer lectin.The results showed that agglutinative activity of Pinellia pedatisecta was four times more than that of Pinellia ternate.The differences of the agglutinative activity and pharmacologic action were mainly because two site mutations of Pinellia pedatisecta in the third active site compared with the amino acids sequence in Pinellia ternate.In addition,the metamer lectin expressed by prokaryotic expression system did not agglutinate rabbit red blood cells.It conduct further discussion about the difference between two lectins and the difference between polymer lectin and metamer lectin.It would be applicable for solving the problem of lacking Pinellia resources.

Objective To observe the effect of artificial nose in the artificial airway humidity among the elderly patients with artificial airway. Methods Sixty-eight patients undergoing artificial airway at department of respiratory were randomly divided into 2 groups, 34 of them in the artificial nose airway humidity group, and 34 in the regular humidity group. The quantity of sputum secretion, times of sputum absorption, degree of airway humidity and acute reaction of respiratory tract were observed. Results The artificial nose airway humidity group was better than the regular humidity group in view of reducing the quantity of sputum secretion, times of sputum absorption, degree of airway humidity and acute reaction of respiratory tract, with significant meanings by the analysis of Chi square test and T test (P<0.01). Conclusions Artificial nose is superior to the method of regular humidity in respect of reducing the quantity of sputum secretion and times of sputum absorption, keeping well effect of airway humidification, and reducing the complications of artificial airway.

Objective To analyze the epidemiologic characteristics of epidemic hemorrhagic fever syndrome (EHF) from 2004 to 2010 and provide scientific basis for formulating control measures.Methods Epidemiological data of EHF between 2004 to 2010 were obtained from the“National Disease Surveillance Report on Management Information System”,and the population data were from the“National Disease Surveillance Information Management System for Basic Information Report System”.Descriptive epidemiological methods was used for statistical analysis.ResultsA total of 173 cases were reported in Qian'an from 2004 to 2010.From 2004 to 2010,the cases were 86,67,12,1,0,1,and 7 cases,respectively,and the rate were 13.12/10 million ( 86/640 249 ),10.42/10 million (67/642 688 ),1.86/10 million ( 12/645 124),0.15/10 million (1/647 983 ),0(0/650 720),0.15/10 million( 1/653 839),and 0.11/10 million(7/657 380),respectively.The overall rate was 3.86/10 million(25/648 283) of population.From 2004 to 2008 the incidence reported declined rapidly,then increased slowly after 2009.The cases were found intensively in winter(November - next January) and spring season (february - may).The incidence in the age group of 10 - 45 was higher than that of other age groups,and the total number of cases was 82.08％(142/173).The incidence in males( 114 cases) was higher than that of females(59 cases).Occupational distribution mainly to peasants and students,which accounted for 87.86％ (152/173).Conclusions Epidemic in the city declines rapidly follows by a slow recovery,suggesting that in the future surveillance,mice-killing and protection of vulnerable population should be strengthened.

OBJECTIVETo investigate the association of genetic polymorphism Val384Asp in hMLH1 gene with the risk of colorectal, gastric, esophageal and breast carcinomas.

METHODSA case-control study was taken to investigate the role of Val384Asp in hMLH1 gene in developing these four carcinomas. 233 colorectal, 273 gastric, 90 esophageal and 111 breast cancer patients were included, as well as 268 healthy individual served as controls. Peripheral white blood cell DNA was obtained from all subjects. hMLH1 gene Val384Asp was analysed using a PCR-based DHPLC while the existence of Val384Asp were verified by DNA sequencing.

RESULTS6.34% of the healthy individuals were identified as Val384Asp carriers and significant differences existing between colorectal cancer patients or gastric cancer patients and controls, especially between young aged patients and controls.

CONCLUSIONDetermination of Val384Asp in hMLH1 gene single nucleotide polymorphism seemed to be suitable for identifying individuals with increased risk of gastrointestinal cancer in the Chinese population.
