Comparison the cognitive function self-evaluation in community dwelling elderly through different interview manner / 中风与神经疾病杂志

@#Objective To investigate the evaluation of cognitive function among elderly people in Shanghai community,compare the differences between telephone and spot interview methods,and provide reference for preliminary screening of cognitive dysfunction in the community. Methods A multi-stage cluster sampling method was used to select 5 084 elderly people in Shanghai. Self evaluation tools AD8,PHQ-9,and GAD-7 were used to conduct spot,telephone,and mixed questionnaire surveys. Result Total 4 253 valid questionnaires were collected,and the effective rates of the spot survey group,mixed survey group,and telephone survey group were 91.50%,83.33%,and 81.90%,respectively. The detection rates of low self-evaluation cognitive function were 36.34%,19.08%,and 9.53%,respectively. There was a significant difference in the average AD8 scores among the three groups (P<0.05);Logistic regression analysis shows that depression is the same influencing factor for cognitive function self-evaluation among the three groups of elderly people. Conclusion The self-evaluation cognitive function of elderly people in the community is affected by depression,and there are differences in the results obtained during spot interviews and phone surveys.

Treatment of degenerative scoliosis with oblique lateral lumbar interbody fusion combined with long-segment internal fixation through navigation for posterior / 中国骨伤

OBJECTIVE@#To assess the early clinical effects of oblique lateral lumbar interbody fusion (OLIF) combined with posterior long-segment internal fixation through O-arm CT navigation for the treatment of degenerative scoliosis.@*METHODS@#The clinical data of 15 patients with degenerative scoliosis treated by OLIF combined with posterior long-segment internal fixation through O-arm CT navigation between April 2016 and December were retropectively analyzed. There were 3 males and 12 females, aged from 55 to 73 years old with an average of (62.2±5.3) years. The operation time, intraoperation blood loss, the rate of excellentand good of pedicle screw placement, and complications were recorded. Before surgery, 1 week after surgery and at the final follow-up, the visual analogue scale (VAS) and Oswestry Disability Index (ODI) were used to evaluate the patients' clinical symptoms;standing X-ray film, lumbar spine CT examination was performed at 6 months after surgery to observe coronal scoliosis Cobb angle, lumbar lordosis (LL), intervertebral space height, sagittal vertical axis (SVA), intervertebral fusion, etc.@*RESULTS@#The mean operation time and intraoperative blood loss were respectively (98.7±16.8) min and (50.2±10.7) ml in OLIF surgery, while were (101.5±23.4) min and (63.1±19.7) ml in the surgery of posterior long segment internal fixation. The total mean operation time and intraoperative blood loss were (200.2±40.2) min and (113.3±30.4) ml. All patients were followed from 12 to 25 months with an average of (16.5±5.3) months. Low back pain VAS, lower limb pain VAS and ODI reduced from preoperative (6.8±1.6), (6.2±1.1) scores and (64.6±10.4)% to (1.4±1.0), (1.0±0.5) scores, and (15.8±4.5)% at the final follow-up, the differences were statistically significant(<0.05). Coronal scoliosis Cobb angle and SVA decreased from preoperative (20.3±13.5)°, (42.3±16.5) mm to (5.5±3.1)°, (25.1±10.9) mm at the final follow-up, and the differences were statistically significant (<0.05). LL and intervertebral space height increased from preoperative (25.8±8.2)°, (5.9±2.7) mm to (39.3±9.1)°, (10.9±1.2) at the final follow-up, and the differences were statistically significant(<0.05). Total 240 nails were placed through O-arm CT navigation with the rate of excellent and good of 96%(230/240). Six months after operation, CT of lumbar spine showed interbody fusion of bone. One patient developed anterior medial pain in the left thigh, and two patients experienced transient lefthip flexion after surgery, both of whom recovered during subsequent follow-up.@*CONCLUSION@#The early clinical effect of oblique lateral lumbar interbody fusion combined with posterior long segment internal fixation through O-arm CT navigation is satisfactory in treatment of degenerative scoliosis. It has the advantages of minimal invasion, accurate navigation of nail placement, high bone fusion rate and few complications. It can provide new options for minimally invasive treatment of degenerative scoliosis.

Single center comparative analysis of hematopoietic cell transplantation from alternated donor in patients with hematologic malignancies / 中国实验血液学杂志

<p><b>OBJECTIVE</b>One of the truly revolutionary advances in hematopoietic cell transplantation (HCT) is the increasingly successful use of alternative donors, as only 1/4 of patients who require an allogeneic hematopoietic cell transplant will have a HLA-matched sibling donor. Thereby, three alternative graft sources: umbilical cord blood (UCB), haploidentical (hi) related donor and mismatched unrelated donor hematopoietic cell transplantation (MMUDT) are available. This study was purposed to compare the characteristics of umbilical cord blood transplantation(UCBT), haplaidentical (hi) related donor hematopoieetic cell transplantation(hi-HSCT) and MMUDT.</p><p><b>METHODS</b>The clinical date of 93 patients with hematologic malignancies who received UCBT (n = 22), hi-HSCT (n = 42) and MMUDT (n = 29), and the days of hematopoietic reconstration and engraftment, rate of acute graft-versus-host disease (GVHD), relapse rate, and overall survival (OS) were analysed.</p><p><b>RESULTS</b>The median days of hematopoietic reconstitution (WBC>1.0×10(9)) among UCBT recipients were significantly longer than those among hi-HSCT/MMUDT recipients, (19 in UCBT, 12 in hi-HSCT and 12 in MMUDT)(P < 0.001), whereas the median days of full engraftment (STR >95%) among hi-HSCT recipients were longer than those among UCBT/MMUDT recipients (26 in hi-HSCT, 15 in UCBT and 20 in MMUDT, P = 0.028), the implant failure rate of UCBT recipients was higher than others (26% in UCBT, 5% in hi-HSCT, 3% in MUUDT)(P < 0.05). Multivarite analysis demonstrated no apparent differences in the rate of aGVHD (50% in UCBT,57.1% in hi-HSCT and 72.4% in MMUDT) (P = 0.498), and the rate of III-VI aGVHD also was no significant defference (27.3% in UCBT, 28.6% in hi-HSCT and 17.2% in MMUDT)(P = 0.543), the rate of chronic GVHD of UCBT recipients was lowered (19.0% in UCBT, 45.5% in hi-HSCT, 58.3% in MMUDT, P = 0.026). Overall survival at 2 years was 79.9% in UCBT, 80.9% in hi-HSCT and 88.0% in MUUDT (P = 0.097), and the TRM in 100 days was 23.8% in UCBT, 20.0% in hi-HSCT and 11.1% in MMUDT (P = 0.245) respectively.</p><p><b>CONCLUSIONS</b>The UCBT is characterised by lowest rate of cGVHD, but its hematopoietic recostruction is slow; the hi-HSCT has more alternative donors for using in clinic and can achieve post-transplant adoptive cellular immunotherapy, but its TRM has been found to be higher; the first important problem for MMUDT is to decrease the higher incidence of aGVHD and cGVHD.</p>

<p><b>OBJECTIVE</b>To explore the relationship between the expression of CD20 antigen and clinical characteristics in adult patients with B-acute lymphoblastic leukemia(B-ALL).</p><p><b>METHODS</b>The CD20 expression of 126 acute lympho-blastic leukemia patients in our hospital from July 2009 to July 2012 were determined by flow cytometry. The characteristics, examination results and outcome were analyzed retrospectively. The complete remission rate (CR rate), relape rate, 2-year survival rate and 2-year event-free survival (EFS) of patients with CD20 positive and negative after the first cycle of chemstherapy were compared.</p><p><b>RESULTS</b>Positive rate of CD20 antigen expression in 126 patients was 24.4% (31 cases), negative rate of CD20 antigen expression in 126 patients was 75.6% (95 cases). No significant relationship was found between CD20 antigen expression and sex, age, peripheral blood leucocytes count and chromosomal changes. The relapse rate, 2-year survival rate (OS) and 2-year event-free survival (EFS) of adult patients with B-ALL in CD20 positive and negative groups were 53.3% and 38.0%, 52.1% and 92.3%, 33.7% and 70.8% respectively.</p><p><b>CONCLUSION</b>Expression of CD20 in adult patients with B-ALL did not related with clinical features, but related with poor prognosis.</p>

Effect of decitabine on immune regulation in patients with acute myeloid leukemia after allogeneic hematopoietic stem cell transplantation / 中国实验血液学杂志

Based on the representative articles in recent years, the different mechanisms of decitabine on immune regulation in patients with acute myeloid leukemia (AML) after allogeneic hematopoietic stem cell transplantation (HSCT) are summarized. Decitabine improves the expression of WT1 gene to stimulate specific cytotoxic T cells which can enhance graft versus leukemia effect (GVL) and improve the expression of FOXP3 gene to stimulate regulatory T cells so as to inhibit the acute graft versus host disease (GVHD). Through the above-mentimed mechanisms, decitabine can improve both therapeutic effect and quality of life in the patients with AML after allogeneic HSCT.

Microbubbles targeted to P-selectin for evaluating testicular ischemia-reperfusion injury in rabbits / 中华男科学杂志

<p><b>OBJECTIVE</b>To explore the feasibility of evaluating complete ischemia-reperfusion injury (IRI) of the testis by contrast-enhanced ultrasonography with microbubbles (MB) targeted to P-selectin (MBp) in rabbits.</p><p><b>METHODS</b>We randomly divided 30 healthy adult rabbits into five groups of equal number (control, 0.5 h IRI, 1 h IRI, 2 h IRI, and 4 h IRI), prepared phospholipid MB and MBp, and performed contrast-enhanced ultrasonography of the bilateral testes with MB or MBp at an interval of 20 min at different times after IRI. When MB or MBp disappeared completely in the healthy testis at 4 to 5 min after intravenous injection, we recorded the power of the first frame (F-P) in the IRI testes followed by immunohistochemical staining of the testis tissue.</p><p><b>RESULTS</b>CEU with MBp achieved a significantly higher F-P than that with MB in all the IRI groups (P < 0.05), which was (8.34 +/- 1.20) versus (1.87 +/- 0.25) 10(-5) AU at 2 hours, but there was no significant difference between MB and MBp in the control rabbits (0 AU, P > 0.05). Immunohistochemistry showed a significantly time-dependent increase in the expression of P-selectin in the vascular endothelial cells of the IRI testes, but not in those of the control.</p><p><b>CONCLUSION</b>Contrast-enhanced ultrasonography with MBp can be used to evaluate the inflammatory reaction of testicular ischemia-reperfusion injury.</p>

Epidemiological survey on pre-hypertension and hypertension prevalence among adolescents aged 11 to 17 years in Shanghai / 中华心血管病杂志

<p><b>OBJECTIVE</b>To assess the prevalence of pre-hypertension and hypertension as well as the association with overweight/obesity in Shanghai adolescents.</p><p><b>METHODS</b>School children aged 11 - 17 years in four schools in Shanghai were included in this survey. All students were visited in May 2010 at school by trained nurses or physicians who administered a questionnaire and carried out anthropometric measurements. Anthropometric measurements included height, weight, heart rate and blood pressure. Repeat measurements were performed in school children with elevated blood pressure within one month. The pre-hypertension and hypertension was defined on the basis of the 2004 National High Blood Pressure Education Program Working Group definitions. The overweight and obesity was defined using cutoff points recommended by Working Group of Obesity, China (WGOC).</p><p><b>RESULTS</b>There were 4175 school children aged 11 - 17 years [mean (15.0 ± 1.9) years, 52.3% (n = 2183) girls and 47.7% (n = 1992) boys]. There were 72.5% (n = 3025) participants with normal blood pressure [ girls (n = 1666) 76.3% and boys (n = 1361) 68.3%], 18.0% (n = 750)participants with pre-hypertension [14.2% (n = 310) for girls and 22.1% (n = 440) for boys], 8.3% (n = 346) participants with stage 1 hypertension [8.2% (n = 179) for girls and 8.3% (n = 165) for boys] and 1.3% (n = 54) participants with stage 2 hypertension [1.3% (n = 28) for girls and 1.3% (n = 26) for boys]. The prevalence of overweight and obesity was 6.7% (n = 147) and 3.0% (n = 66) for girls and 13.7% (n = 273) and 6.3% (n = 125) for boys. After adjusting for gender, age, parental history of hypertension and physical activities, multivariable logistic regression analysis showed that the overweight [adjusted odds ratio and 95% confidence interval: 1.42 (1.16 - 1.75)] and obesity [adjusted odds ratio and 95% confidence interval: 2.35 (1.78 - 3.11)] were independent predictors of elevated blood pressure in this cohort.</p><p><b>CONCLUSIONS</b>The prevalence of elevated blood pressure is common in adolescents in Shanghai. Overweight and obesity are closely associated with the elevated blood pressure in this cohort.</p>
