Objective To analyze the changes of P wave of intracavitary electrocardiogram (ECC) in the placement of periph erally inserted central venous catheters (PICC), and to explore whether the intracavitary ECG can be used to guide the procedure. Methods PICC was inserted in 62 adult patients under intracavitary ECC-guided technique. The intracavitary ECC were recorded in different parts of vessel access through micro-guidewire. Results The intracavitary ECG extracted through micro-guidewire were accurately recorded in all patients. The amplitudes of P wave were (1.11 ±0.36)mm, (1.12±0.28)mm,(1.56±0.45)mm, (4.03±1.87)mm, (5.90±2.45)mm, (7.90±2.95)mm, (9.87±2.77)mm, (5.00±1.76)mm, (2.50±1.73)mm when PICC tip was located in the axillary, subclavian and brachiocephalic vein, in the superior, middle and inferior SVC, at the SVC-right atrium junction, and in the middle, inferior right atrium,respectively. The amplitude of P wave was 1.14±0.34mm in 10 patients with PICC tip malposition in the internal jugular vein. Conclusions The intracavitary ECG can be extracted with the microguidewire of PICC system. The amplitude of P wave is related to the location of PICC tip, which can be used to guide the PICC insertion and positioning.

Objective To assess the value of C-reactive protein(CRP) for the prognosis of acute pulmonary embolism (PE). Methods 56 acute pulmonary embolism patients, confirmed by spiral computed tomography (sCT), magnetic resonance imaging(MRI), or pulmonary angiography (CTPA). CRP as well as electrocardiogram (ECG), echocardiography(UCG), blood gas analysis, were taken after admission. Results Among these patients,24 cases with higher CRP(≥10 mg/L),were diagnosed as massive (50.0%), sub-massive PE(45.8%), mini-massive (4.2%) or died(25.0%). 24 cases (100.0%) showed right heart dysfunction and 24 cases showed pulmonary hy-pertension on UCG, right ventricular 20 (83.8%) on ECG, 22 cases (91.7%) showed hypoxemia. 8 cases (33.3%) had syncope,and 9 cases (37.5%) had cardiogenic shock. CRP was lower than 10 mg/L in 32 patients, among whom,3 cases (9.4%) were with massive PE,6 cases (18.8%) were with sub-massive PE,23(71.8%) were with small PE,1 cases(6.3%) died. 13 (40.6%) had right heart dysfunction and 16(50.6%) had pulmona-ry hypertension on UCG, right ventricular on ECG in 15 cases (46.9%), hypoxemia in 11 cases (34.4%), syncope in 2 cases (6.3%), cardiogenic shock in 4 cases (12.5%). The occurrence of massive PE, mortality (P<0.01) and sub-massive PE (P<0.05)were statistically different between the groups with higher CRP and the groups with lower CRP. The ratio of right heart dysfunction, pulmonary hypertension, right ventricular overloading, hypoxemia had statistical significance (P<0.01). There was statistical significance in the occurrence of syncope, cardiogenic shock (P<0.05). Conclusions CRP can be used as a parameter for PE, and can be used to stratify risk levels for severi-ty and assess the effectiveness of treatment.

OBJECTlVE To study the effect of ganoderma poIysaccharide( GLP)on zebrafish ( Danio rerio)survivaI,deveIopment and senescence. METHODS A p53-knockout zebrafish modeI was estabIished by injecting of morphoIino phosphorodiamidate(mO)into normaI zebrafish eggs in the singIe ceII deveIopment stage. Different concentrations of GLP 1,2 and 3 g·L-1 were used to treat both wiId type and p53-knockout zebrafish embryos 8 h post fertiIization(8 hpf)under 28℃ for 3 d. The survivaI and maIformation rates were caIcuIated after 72 hpf,and the effect of GLP on ceII senescence was evaI-uated by senescence associated β-gaIactosidase(SA-β-gaI)staining both in wiId type and p53-knockout zebrafish embryos. In addition,the differentiaI gene expression of cancer inhibitor gene(p53),teIomer-ase reverse transcriptase( TERT),murine doubIe minute2( mdm2)and p21 was examined by RT-PCR both in wiId type and p53-knockout zebrafish embryos after treatment with different concentrations of GLP. RESULTS GLP 1 and 2 g·L-1 had no effect on deveIopment of wiId type zebrafish embryos,but after GLP 3 g·L-1 treatment,most of zebrafish embryos dispIayed maIformation and the survivaI rate was onIy 48.6%. GLP 1,2 and 3 g·L-1 had no effect on survivaI and deveIopment of p53-knockout zebrafish embryos. After GLP 2 g·L-1 treatment for 3 d,the SA-β-gaI staining positive rate of wiId type zebrafish embryos was reduced compared with controI group(P﹤0.01),whiIe there was no significant change in p53-knockout zebrafish embryos. The resuIts of RT-PCR showed that GLP 2 g·L-1 treatment depressed p21 and p53 gene expression(P﹤0.05,P﹤0.01),and had no effect on mdm2 and TERTgene expres-sion of wiId type zebrafish embryos. For p53-knockout zebrafish embryos,the TERT,mdm2,p21 and p53 gene expression dispIayed no significant difference after GLP 2 g·L-1 treatment. CONCLUSlON GLP 2 g·L-1 may improve senescence of wiId type zebrafish embryo ceIIs. GLP ≥3 g·L-1 may Iead to death and abnormaI deveIopment of wiId type zebrafish embryos. The improvement of GLP on senescence of wiId type zebrafish embryo ceIIs might be mediated by its down-reguIation of p21 and p53 gene expression.

ObjectiveTo explore relationship between psychological resilience and life events of Tibetan nursing students receiving free vocational nursing education.Method The questionnaire of Symptom Checklist 90(SCL-90)and ASLEC were used in the survey among 120 nursing students to investigate the psychological resilience and life events and SPSS 17.0 was used to look into the correlations between them.Results The scores on psychological resilience of Tibetan nursing students was higher than the norm (P<0.05).There were negative correlations between life events and psychological resilience(P<0.05).Their psychological resilience was positively related to personal relations and health conditions(P<0.05)but negatively to learning pressure,punishment and losses (P<0.05).Conclusion The school and hospital should make teaching measures to psychologically support them in daily life to strengthen the abilities to handle failure and adjust to the society.

Objective To explore the relationship between acid pocket and acid reflux in gastroesophageal reflux disease (GERD).Methods From March 2011 to January 2012,29 patients with GERD were enrolled and nine healthy individuals were set as control.All objects of this study accepted esophageal manometry test,acid pocket test,test of the occurrence time of acid pocket and ambulatory 24 hours pH monitoring.The t-test was performed for comparison between two groups.The relationship between the incidence of GERD and acid pocket was analyzed by Logistic regression analysis.Pearson correlation analysis was used for correlation analysis.Results The percentage of acid pocket in GERD group and control group was 58.6％ (17/29) and 5/9,respectively,and the difference was not statistically significantly (P＞0.05).The duration time of acid pocket was (56.3±44.7) minutes in GERD group which was longer than that of control group ((16.0±8.2) minutes) and the difference was statistically significant (t=1.970,P＜0.01).There was no statistical significance in the average pH value of acid pocket between GERD group with acid pocket (2.8 ± 1.3) and that of control group with acid pocket (1.9±0.5,P＞0.05).The duration time of acid pocket was correlated with the longest reflux time in GERD group with acid pocket (r=0.550,P＜0.01).The peak velocity of esophageal motility in GERD group ((3.3±0.6) cm/s) was lower than that of control group ((5.0±4.1) cm/s) and the difference was statistically significant (t=-1.354,P＜0.05).The peak velocity of esophageal motility in GERD group with acid pocket ((3.2±0.6) cm/s) was lower than that of control group with acid pocket ((7.2± 6.3) cm/s) and the difference was statistically significant (t=-2.693,P＜0.05).Conclusions The duration time of acid pocket in GERD is correlated with the time of acid reflux.Esophageal dysmotility may be related with the pathogenesis of GERD and the occurrence of acid pocket.
