Objective To summarize the phenotypic features of an unrecognized leukoencephalopathy in infants sharing same clinical features,and to better understand the disease and provide new evidence for identification of new leukoencephalopathy. Methods Clinical and follow-up data of 13 patients with unrecognized infantile leukoen-cephalopathy were collected from Peking University First Hospital from January, 2006 to December, 2014. Results (1) There were 7 male and 6 female. The average age of onset was 11 months (4-25 months). Thirty-eight percent (5/13 cases) of patients had incentives before the onset;all of the cases had acute onset and rapid motor function regression. Fifteen percent (2/13 cases) of the patients suffered from seizures in the course of the disease. Patients′condition became stable,and cognition and motor function improved gradually 1 month after onset. No patient died till the last follow-up. (2) Imaging features:magnetic resonance imaging (MRI) of the patients was characterized by im-plicating deep white matter,presenting T1 hypointense,T2 and fluid attenuated inversion recovery ( FLAIR) hyperin-tense in the periventricular area. All of MRI showed massive and symmetric lesions with heterogeneous signal and cystic degeneration. DWI showed patch or massive hyperintense in some of the lesions. The follow-up MRI showed the original lesions decreased in 88% ( 8/9 cases ) of patients, and white matters atrophied in 55% ( 5/9 cases ) of patients;the cystic degeneration still existed and even expanded;DWI showed regional linear or spot hyperintense in 88% (8/9 cases) of patients,which was smaller than before,and distributed around the original lesions. Conclusions The patients with leukoencephalopathy caused by unknown pathogenic gene were much likely to be mitochondrial leukoencephalopathy. This study provided evidence for further exploration of new pathogenic genes causing leu-koence-phalopathy.

Objective To explore the influence of the self-efficacy nursing on compliance behavior of patients with cervical cancer.Methods Totals of 153 patients from November 2012 to November 2013 diagnosed as uterine cervical neoplasms and treated by surgical procedure were selected, within which 86 patients joined the research and were divided into observation group and control group, 43 cases in each group. The control group was given the routine nursing care, and the observation group was given the self-efficacy nursing intervention on the basis of conventional nursing.The self-efficacy and compliance behavior were surveyed before and after the intervention.Results The scores of self-efficacy before the intervention had no statistically significant difference (t=0.158,P>0.05).After the intervention, the score of the observation group was (35.15 ±5.21), which was significantly higher than (21.26 ±8.26) of the control group ( t=15.684,P<0.01) .The score of self-efficacy of the observation group before and after the intervention were statistically significant (t=15.124,P<0.01), while the self-efficacy in the control group before and after the intervention had no statistically significant difference (t=1.245,P>0.05).After the intervention, the scores of compliance of medication, reasonable break, regular examination, healthy diet, abstain from tobacco and drink, reasonable exercise, prevention of infection and the total score were (2.85 ±0.41), (2.92 ±0.56), (2.81 ±0.44), (2.75 ±0.46), (1.87 ±0.41), (2.79 ±0.54), (2.88 ±0.39) and (18.75 ±1.65), which were significantly higher than those of the control group ( t=5.124, 6.235, 5.842, 4.963, 4.698, 5.148, 6.398, 5.458, respectively;P<0.01).Conclusions Self-efficacy nursing intervention can improve the self-efficacy of uterine cervical neoplasms patients, enhance patients’ self-management level, and enhance confidence on health compliance behavior.

OBJECTIVETo identify human single chain Fv antibody (ScFv) against hepatitis B viral surface antigen.

METHODSThe recombinant phages were panned by HBsAg which was coated in a microtiter plate, after five rounds of biopanning, 56 phage clones were identified specific to HBsAg. The specificity of ScFv was evaluated by ELISA and immunohistochemistry, respectively.

RESULTSThe data of HB sAg-ScFv DNA digestion and DNA sequencing showed that the ScFv gene is composed of 750 bp. ELISA and immunohistochemistry demonstrated that the human single chain Fv antibody against hepatitis B surface antigen has a specific combination character with hepatitis B surface antigen of different sources and paraffin-embedded patients tissue specimens, it did not react with normal liver tissue and HCV.

CONCLUSIONSThe application of HBsAg specific ScFv in immunohistochemistry was successfully achieved.

Objective To investigate the effects of AIDS and tuberculosis(TB)co-infection on CD8+T lymphocytes.Methods Serum CD8+T cells and CD4+T cells were analyzed and compared between human immunodeficiency virus(HIV)alone patients(n=200),TB alone patients(n=200),and HIV/TB co-infection patients(n=200).Results CD8+T cells were significantly higher in HIV alone group compared to HIV/TB co-infection group and TB alone group(x2=128.779,P＜0.001).The level of CD8+T lymphocytes in HIV/TB co-infection group and HIV alone group was higher than normal level(ZHIV/TB=8.343,PHIV/TB＜0.001,ZHIV=7.988,PHIV＜0.001).The CD8+T cells in TB alone group decreased significantly compared with normal levels(ZTB=8.682,PTB＜0.001).The levels of CD4+T cells in the three groups of patients were all lower than normal(ZHIV=11.088,PHIV＜0.001,ZTB=5.562,PTB＜0.001,ZHIV/TB=12.077,PHIV/TB＜0.001).The stratified analysis of CD8+T cell levels by CD4+T cell counts,showed that when CD4+T cell count was≤100 cells/μL,the level of CD8+T cells in HIV alone group was higher than that in TB alone group.HIV alone group had higher CD8+T cells than HIV/TB co-infection group,and the level of CD8+T cells in HIV/TB co-infection group was significantly lower than normal(Z0-100=1.604,P0-100=0.109).When CD4+T cells ≥101 cells/μL,HIV/TB co-infection group had higher CD8+T cells than TB alone group.HIV alone group had higher CD8+T cells than TB alone group.When CD4+T cells＞500 cells/μL,CD8+T cell levels were within the normal range in all three groups of patients.Taking the HIV alone group as a reference,with the decrease of CD4+T cell count,the CD8+T cell count decreased more significantly in TB alone group and HIV/TB co-infection group than in HIV alone group(slope was 0.344 and 0.216,respectively,P＜0.001).Conclusions With the decline of CD4+T cells,both HIV/TB co-infection and TB alone are associated with decrease in CD8+T cells,and the decrease in the TB alone group is more prominent.

Objective To evaluate the effect of "health education mobile classroom " in the outpatient department of children's hospital, and to analyze the needs of the outpatient and family members on health education. Methods Through the retrospective analysis of the information of the outpatient and emergency patients in the children's specialist hospital to determine the content, the venue and the time period of the "health education mobile classroom". Selection and training the health educator to implement the health education. At the same time, push the training content through the mobile APP to the patient's family, to expand the education audience. To compare and analyze the patient satisfaction of the hospital and the satisfaction with the dimensions of the project. In the evaluation of the effect of health education and the influencing factors, the relationship between income, occupation and children is positively related, and age is negatively related to it. Results After the implement of this project, the satisfaction of the patient had increased for 3.65%(P=0.001). Overall assessment of the audience was very satisfied with (3.94 ± 0.25) points. In each dimension analysis, the satisfaction of the "training method"was the highest, at (3.94 ± 0.26) points. Satisfied with the attitude of the trainers and comprehensive ability were more than 3.80 points. Conclusions The "health education mobile classroom" can improve patient satisfaction in the outpatient department and emergency of children's specialist hospital. Audience has a certain degree of acceptance and satisfaction with this health education mode.
