Objective To investigate the clinical nursing path on the psychological status of cerebral infarction patients hospitalized for the first time.Methods Two hundred cerebral infarction patients hospitalized for the first time were equally randomized into the observation group and control group:the former used conventional nursing method and the latter a clinical nursing path.The self-rating depression scale(SDS)and self-rating anxiety scale(SAS)were used to assess their psychological state.Results After intervention,the scores on SDS and SAS in the former group were significantly lower than those in the latter group(all P<0.05). The satisfaction rate in the former was higher than that of the control(P<0.05).Conclusion The clinical nursing path makes it possible to effectively alleviate the psychological burden of the cerebral infarction patients hospitalized for the first time and improve the patients’satisfaction with nursing working.

The optimal plane for measurement of the right ventricular (RV) volumes by real-time three-dimensional echocardiography (RT3DE) was determined and the feasibility and accuracy of RT3DE in studying RV systolic function was assessed. RV "Full volume" images were acquired by RT3DE in 22 healthy subjects. RV end-diastolic volumes (RVEDV) and end-systolic volumes (RVESV) were outlined using apical biplane, 4-plane, 8-plane, 16-plane offline separately. RVSV and RVEF were calculated. Meanwhile tricuspid annual systolic excursion (TASE) was measured by M-mode echo. LVSV was outlined by 2-D echo according to the biplane Simpson's rule. The results showed: (1) There was a good correlation between RVSV measured from series planes and LVSV from 2-D echo (r = 0.73; r = 0.69; r = 0.63; r = 0.66, P < O. 25-0. 0025); (2) There were significant differences between RVEDV in biplane and those in 4-, 8-, 16-plane (P < 0.001). There was also difference between RV volume in 4-plane and that in 8-plane (P < 0.05), but there was no significant difference between RV volume in 8-plane and that in 16-plane (P > 0.05); (3) Inter-observers and intro-observers variability analysis showed that there were close agreements and relations for RV volumes (r = 0.986, P < 0.001; r = 0.93, P < 0.001); (4) There was a significantly positive correlation of TASE to RVSV and RVEF from RT3DE (r = 0.83; r = 0.90). So RV volume measures with RT3DE are rapid, accurate and reproducible. In view of RV's complex shape, apical 8-plane method is better in clinical use. It may allow early detection of RV systolic function.

This study aims to investigate the genetic characteristics of BZLF1 gene and its promoter Zp of the epidemic strains in children with primary Epstein-Barr virus (EBV)-associated diseases. Total DNA was extracted from the peripheral blood of 134 children with EBV-associated infectious mononucleosis (EBV-IM) and 32 children with EBV-associated hemophagocytic lymphohistiocytosis (EBV-HLH) who were admitted to Beijing Children's Hospital from 2006 to 2011. The EBNA3C, BZLF1, and Zp genes were amplified by PCR assay. Typing of EBV was performed according to the size of the amplification product of EBNA3C gene; the amplification products of BZLF1 and Zp genes were subjected to direct sequencing, and sequence analysis was performed using BioEdit 7. 0. 9. The results were as follows: (1) EBV-1 was present in 140 samples (97.2%, 140/144) and EBV-II in 4 samples (2.8%, 4/144). (2) Three BZLF1 genotypes and their 12 subtypes (including 6 newly found subtypes) were detected in this study; there were no significant differences in the frequencies of BZLF1-A and BZLF1-B between the children with EBV-IM and EBV-HLH (P = 0.083); BZLF1-A1 was the dominant genotype in children with EBV-associated diseases; t BZLF1-A mostly had three 29-bp repeats in the first intron of BZLF1 gene, and BZLF1-B mostly had 30-bp repeats (P = 0.000), with the number of repeats varying from 1 to 13. (3) Four Zp genotypes were detected in this study, including Zp-P, Zp-V3, Zp-V4, and Zp-V1; there were no significant differences in the frequencies of these Zp genotypes between children with EBV-IM and EBV-HLH (P = 0.272, 0.252, 1.0, and 1.0, respectively). (4) The linkage analysis of BZLF1 gene and its promoter Zp showed that BZLF1-A1 was highly associated with Zp-V3 (P = 0.000), while BZLF1-B4 with Zp-P (P = 0.000); EBV-I + BZLF1 A1 was highly associated with Zp-V3 (P = 0.000), while EBV-I+BZLF1-B4 with Zp-P (P = 0.000). The conclusions are as follows: (1) BZLF1-A1 is the dominant genotype in children with EBV-associated diseases; there are mostly 29-bp repeats in the first intron of BZLF1 gene for BZLF1-A genotype and 30-bp repeats for BZLF1-B genotype. (2) Zp-P and Zp-V3 are dominant Zp genotypes of EBV in children, which shared similar detection rates. (3) BZLF1-A1 is highly associated with Zp-V3, while BZLF1-B4 with Zp-P; EBV-I+BZLF1-A1 is highly associated with Zp-V3, while EBV-I+BZLF1-B4 with Zp-P.

This paper is to report the study of resveratrol-induced apoptosis and its mechanisms in MCF-7 cells. MTT assay was performed to assess the cytotoxicity of resveratrol on MCF-7 cells. Hoechst 33258 staining was used to observe cellular morphologic changes in apoptosis. Apoptosis was measured by flow cytometric analysis and the protein expression was examined by Western blotting analysis. The results indicated that resveratrol could inhibit MCF-7 cell growth in a time- and concentration-dependent manner. Remarkable morphologic changes in the cells after 60 micromol L(-1) resveratrol treatment, including cell nuclear shrinkage, DNA condensation and apoptotic bodies, were observed by Hoechst 33258 staining. Resveratrol could induce apoptosis and activate p38 and p53 in a time dependent manner in MCF-7 cells. In addition, the cell growth inhibitory ratio and the apoptotic ratio of resveratrol-treated group decreased markedly by the p38 MAPK inhibitor SB203580 or p53 inhibitor pifithrin-alpha. Further experiments confirmed that resveratrol-induced p53 activation was reduced by SB203580 whereas the activation of p38 was not affected by pifithrin-alpha. In conclusion, resveratrol induced apoptosis in MCF-7 cells could be through activating p38-p53 signal pathway.

OBJECTIVETo investigate the coping strategies of the community-based population in Shenzhen.

METHODSTotally 5,940 subjects from the communities in Shenzhen were sampled and tested with the Simplified Coping Style questionnaire.

RESULTSThe most common coping strategies adopted by the community residents in Shenzhen were "consoling themselves" (33.1%) and "looking at the bright side of things" (31.4%), and the least adopted coping strategy was "relieving distress by smoking, drinking, taking medicine and eating" (57.8%); the strategies left out from their choices were mostly negative strategies. The scores for positive coping strategy factors of community residents in Shenzhen were greater than those of negative ones, with a mean difference of 0.43. The scores of both positive and negative coping strategy factors of these residents were significantly lower than those of general population in other mainland cities (P<0.001), with mean differences of 0.12 and 0.36, respectively.

CONCLUSIONThe community residents in Shenzhen adopt mostly positive strategies for coping with frustration, which benefit their status of self-rated health.

BACKGROUNDBrachial-ankle pulse wave velocity (baPWV) is a reliable method for measuring arterial elasticity, but the absence of reference value for baPWV has limited its wide use. We conducted an epidemical study in north China to investigate the reference value of baPWV for Chinese people and its influential factors.

METHODSA total of 974 identified healthy subjects were recruited in this study. The values of baPWV were evaluated noninvasively with an automatic device.

RESULTSFor healthy population, the mean value of baPWV was higher for male (P < 0.001). Multiple regression analysis demonstrated that both age and systolic blood pressure were positively associated with baPWV for male and female (P < 0.001). BaPWV value was higher in male than in female in younger group (< 50 years) but not in older group (P

CONCLUSIONSAging is the most important reason of arterial stiffness, but the effect of age on baPWV augmentation is greater for healthy female than their male counterpart. The reference values of baPWV by sex and age are very useful for clinical and preventive medicine.

Objective To compare real-time PCR and gomori-methenamine silver stain in the diagnosis of pneumocystis peumonia (PCP).Methods 2 525 unrepeated specimens from suspected PCP patient admitted in Peaking Union Medical College Hospital were collected in 2014.2 492 samples were detected by gomori-methenamine silver stain,33 samples were detected by real-time PCR,and 429 samples were detected by both methods at the meanwhile.With clinical diagnosis as reference standard,the sensitivity,specificity,positive predictive value and negative predictive value of the two methods were analysised.Results Positive rate of gomori-methenamine silver stain was 1.2 ％ (30/2 492).The first three specimen types were sputum,tracheal intubation suction and bronchoalveolar lavage fluid,the positive rate was 0.70 ％ (13/1 845),4.00％ (10/250) and 2.72％ (7/257) respectively.Positive rate of realtime PCR was 34.20％ (158/462),and the positive rate of sputum and bronchoalveolar lavage fluid was 30.61％ (105/343) and 44.54％ (53/119) respectively.The sensitivity were 13.97％ vs 72.07％,specificity were 100％ vs 94.24％,positive predictive value were 100％ vs 92.14％ and negative predictive value were 55.36％ vs 78.26％ for gomori-methenamine silver stain and real-time PCR respectively.All of which were statistically significant analysed by x2 test for paired data.The x2 value and P alue were x2 =68.625,P＜0.01;x2 =4.296,P＜0.05;x2 =6.380,P＜0.01 and x2 =11.873,P＜0.01.Conclusion The real-time PCR had higher sensitivity,fewer interference factors and more clinical diagnostic value,so clinicians should make more use of real-time PCR to diagnose PCP earlier.

OBJECTIVE: To explore the effect and toxicity profile of recombinant human interleukin 11(rhIL-11) on the platelet after hematopoietic stem cell transplantation in patients with leukemia. METHODS: Twenty-four patients with acute or chronic leukemia treated by allogeneic peripheral blood stem cell transplantation (PBSCT) were randomly divided into a test group and a control group. The patients in the test group were treated with rhIL-11 since the 13th day after PBSCT (1.5mg/d),while the control group were given symptomatic treatment. RESULTS: The average time for the platelet to recover to the level of 20 x 10(9)/L was 20.8 days in the test group, and 26.0 days in control group respectively, there was significant difference (P<0.01). The average time for the platelet to recover to the level of 50 x 10(9)/L was 25.7 days in the test group, and 32.3 days in the control group respectively, there was also significant difference (P<0.01). The average time for the platelet transfusion was 2.2 in the test group, 4.1 in the control group, and there was significantly different (P<0.01). The average number of megakaryocytes was 12.2 in the test group, 4.8 in the control group on 30th day after the transplantation,and there was significant difference(P<0.01). The main side effects of rhIL-11 were nausea, vomit, debility, headache, dizzy and pain of injection site, and the degree was all Iapproximately II grade. CONCLUSION rhIL-11 has definite recuperative effect on the recovery of the platelet after PBSCT. There is little side effect, and it can be accepted.

OBJECTIVETo explore the relationship of Epstein-Barr virus (EBV) specific antibodies detection and the diagnoses of infectious mononucleosis (IM) caused by EBV.

METHODSSingle serum samples were collected from 220 inpatients with the diagnosis of IM between January 2005 and December 2006 in Beijing Children's hospital. The samples were detected for EBV-CA-IgM, EBV-CA-IgG, EBV-EA-IgG, EBV-NA-IgG and the avidity of EBV-CA-IgG by indirect immunofluorescent assay.

RESULTSThe positive rate of EBV-CA-IgG, EBV-CA-IgM, EBV-EA-IgG and EBV-NA-IgG were 100%, 95.9%, 79.5% and 4.1% respectively. Low-avidity EBV-CA-IgG was detected in 204 patients (92.7%) with positive EBV-CA-IgM and EBV-CA-IgG,negative EBV-NA-IgG, low-avidity EBV-CA-IgG were the main pattern of EBV antibody in IM patients (84.6%).

CONCLUSIONThe existence of EBV specific antibody (CA-IgG, CA-IgM, EA-IgG, NA-IgG and avidity of CA-IgG) could add more information to identify the stage of EBV infection so as to provide more reliable serological evidence for the diagnosis of IM.
