OBJECTIVETo evaluate the clinical efficacy of manipulative reduction combined with percutaneous vertebroplasty (PVP) or percutaneous kyphoplasty (PKP) in treating osteoporotic vertebral compression fracture (OVCF) using meta-analysis method, in order to provide a reference for clinical treatment.

METHODSA systematic computer-based search (from January 1987 to April 2014) from CNKI, Wanfang database, Web of Science and PubMed were performed for the collection of controlled clinical researches on manipulative reduction combined with PVP or PKP in treating OVCF. The quality of selected researches was evaluated. Meta-analysis was adopted to evaluate visual analog scale, Cobb angle, anterior height ratio of the injured vertebra.

RESULTSA total of 7 researches of 410 patients were included in the present analysis, there were 5 RCTs and 2 non-RCTs and all come from China. Manipulative reduction combined with PVP could got better improvement in Cobb angle (WMD=-7.35; 95%CI: -12.15, -2.54) and anterior height ratio of the injured vertebra (P<0.01) than simple PVP, but no significant difference was found in improvement of visual analog scale (WMD=-0.01; 95%CI: -0.45, 0.42). There were no significant differences in the improvement of visual analog scale, Cobb angle, anterior height ratio of the injured vertebra between manipulative reduction combined with PKP and simple PKP (P>0.05).

CONCLUSIONCompared with simple PVP, manipulative reduction combined with PVP may result in more clinical efficacy on the improvement of Cobb angle and anterior ratio of the injured vertebra. And compared with simple PKP, manipulative reduction combined with PKP has no obvious advantages on the improvement of visual analog scale, Cobb angle, anterior height ratio of the injured vertebra. However, the number and quality of the literatures, may resulted in the effect of mistrust, so more large sample and high-quality RCTs are needed in future.

Objective:To evaluate the reliability and validity of the Chinese version of Interpersonal Stress-Coping Inventory for Undergraduates(ISI).Methods:Totally 421 college students of 1～3 grades in two colleges of Anhui province were selected.They were asked to complete the ISI and Simplified Coping Style Questionnaire(SCSQ)at the same time to test the reliability and validity of ISI.Two weeks later,52 of them were retested to test the re-test reliability.Results:Cronbach α of the Chinese version of ISI was 0.79,re-test reliability was 0.87.ISI Scores were correlated with SCSQ scores(r=0.69).Exploratory factor analysis was applied to the data,and three subscales were derived:positive coping,negative coping,and dilution coping.The factor loadinps were 0.41～0.68.The explained variances were 14.82,14.10,and 7.06 respectively.Conclusion:The Chinese version of Interpersonal Stress-Coping Inventory has good psychometric quality and can be used in Chinese undergraduates of interpersonal stress coping research.

Artificial antigen Cd-IEDTA-BSA (HSA) was successfully synthesized by the bifunctional chelating agent IEDTA (isothiocyanobenzylethyl enediamine tetraacetic acid) coupling with cadmium and protein carrier. The fluorescence characteristics of antigen were determined by fluorescence spectrophotometry and the coupling ratio 11∶ 1-16∶ 1 was obtained for the coupling reaction. The folding status of serum albumin during the synthesis process of artificial antigen Cd-IEDTA-BSA (HSA) was analyzed using "fluorescence phase diagram", and the result shows that it was conformed to the "all-or-none" pattern. The polarization fluorescence spectra show that the microenvironments of tryptophan residues in carrier protein have some changes to cause changes in protein conformation.

Objective To explore the serological variations for syphilis in infants delivered by treated syphilitic mothers and its influencing factors. Methods Totally, 146 singleton gravidas, who had been treated for syphilis during pregrancy from January 2006 to January 2008 in our hospital, were chosen. Rapid plasma reagin(RPR) and treponema pallidum particle agglutination assay (TPPA) of these mothers before delivery and of the newborns within 3 d after delivery were tested and 92 of the 146 babies were followed up until the age of 24 months. Results (1) Among the 146 neonates, 104 (71.2%) were positive for both RPR and TPPA and 140 (95.9%) TPPA positive only. The RPR positive rate in neonates born to RPR+ + TPPA+ mothers were higher than those born to TPPA+ (only) mothers (81.4% vs 36.4%,χ2 = 25. 3, P<0. 01). 90.4% of the RPR+ neonates (94/104) showed lower or equivalent RPR titers compared to their mothers. (2) Among the 92 babies bein g followed up, the seroreversion of RPR were found in 98. 2%(n = 56) of the 57 babies, who were RPR+ +TPPA+ at delivery, at the 6 months and 100% (n=57) within 8 months, with the peak time within 2 months after birth (78. 9%, n = 45). While, 100% of the babies were found to be TPPA-within 24 mo with the peak time at 10～18 mo (64. 9%, n = 37). For those babies with TPPA+ at delivery, all turned to be TPPA- at 18 mo, with the peak time at 6 ～ 12 mo (57. 1%, n = 20). (3) The seroreversion time of babies with maternal RPR between 1:1～1:4 was later than those with maternal RPR (P<0.05). The seroreversion time of babies with maternal RPR titer of 1:4 was longer than those with maternal RPR titer of 1 > 1 [(2.5±0.8) mo vs (1. 2±0. 4) mo,P<0. 01]. However, the maternal RPR titer did not affect the TPPA reversion time (P > 0.05). The seroreversion time of RPR in infants with neonatal RPR titer of 1 : 4 was later than those with neonatal RPR titer of 1:1 [(3.7±0. 9) mo vs (2. 3±0. 6) mo,P<0. 01], and babies with RPR titer at 1 : 1 - 1 :4 showed longer duration than those with neonatal RPR- in TPPA seroreversion [(11. 2±2. 8) mo, (12.2±2.9) mo, and (11.0±2.2) mo vs ( 6. 9±2. 1) mo, P< 0.01, respectively]. Conclusions Most infants born to syphilitic mothers are serological positive for syphilis despite of standard maternal treatment during pregnancy. Infants, with higher maternal RPR titer during the pregnancy or at delivery, may persist to be serological positive for syphilis for a longer perieod, but all will turn to negative finally. Long term follow up is recommended for serological positive infants, and the diagnosis of congenital syphilis should be cautious.

Objective To evaluate the immune responses and its dynamic changes of the babies born to hepatitis B surface antigen (HBsAg) positive mothers after combined passive immunoprophylaxis and active immunoprophylaxis. Methods Two hundred and forty-nine infants born to HBsAg positive mothers were enrolled. All of these infants have received both passive immunoprophylaxis by injecting hepatitis B immunoglobuin (HBIG) and active immunoprophylaxis by vaccinated with hepatitis B vaccine simultaneously 12 hours after birth. After that, all infantscompleted the whole vaccination program. The titers of serum HBsAg and hepatitis B surface antibody (HBsAb) of the infants were checked at 7, 12, 24 and 36 months after birth. The data was analyzed by chi square test. Results Infants born to HBsAg positive mothers showed various immune response modes. The no response rate, low response rate and strong response rate were 8.0% (20/249),11.7% (29/249) and 80.3% (200/249) respectively in the 7-month infants, which were 10.8% (12/120), 26.7% (32/120) and 62.5% (75/120) respectively in 12-month infants. The results from further follow-up showed that no response rate, low response rate and strong response rate were 14.8% (4/27), 33.3% (9/27) and 51.9% (14/27) respectively in the 24-month babies and were 14.3 (1/7), 28. 6% (2/7) and 57.1% (4/7) respectively in the 36-month babies. There were statistically significant difference between the 7-month infants group and other groups (x2= 21.98,P＜0.01). The HBsAb titers of high-response infants group declined over time. The infants with higher antibody titers tended to not decline or decline more slowly. In infants who have even achieved HBsAb titers higher than 1000 mIU/mL, 57.6% (19/33) of them showed decreased titers in 36 months. The titer decrease peaked at 24 month after birth (57.9%, 11/19). In infants who have achieved HBsAb titers of 100 to 1000 mIU/mL, 73.8% (31/42) of them showed decreased titers in 36 months. The titer decrease peaked at 12 month after birth (54.8%, 17/31). HBsAg positive infants usually showed no response at 7 month, who accounted for 70% (14/20,x2 = 128.61, P＜0.01) of all no response infants. Ninety-nine percent (189/191) of HBsAg negative infants showed strong responses. The infants born to both HBsAg positive and hepatitis B e antigen (HBeAg)positive mothers tended to show no response. However, the difference between these infants and others was not statistically significant (9.1% vs 5.5%,x2 =0.24,P＞0.05). Conclusions The immune responses of infants born to HBsAg positive mothers after combined passive and active immunoprophylaxis change over time. The non-response status is usually found in HBsAg positive infants. HBsAg negative infants usually show strong response. Infants born to both HBsAg positive and HBeAg positive mothers tend to show low response. It is recommended to follow standard immunoprophylaxis procedure. The follow-up and active monitor are very important during 7 months to 2 years after birth.

Objective:To determine if a group psychotherapy programme offers significant benefits to psycho-logical wellbeing for early and mid-term colorectal cancer patients compared to control group.Methods:Totally 67 patients previously diagnosed with colorectal cancer who participated in this study,34 patients accepted an invitation to join the intervention group,received 10 consecutive,weekly sessions group psychotherapy,and 33 patients served as control subject with usual care only.All participants were assessed at baseline and post-therapy (week 10 follow-ing enrollment or equivalent ).Assessment comprised self-completed Cancer Quality-of-life Core Questionnaire (QLQ-C30),Self-Rating Depression Scale (SDS)and Self-Rating Anxiety Scale (SAS).Results:At baseline, 67participants completed questionnaires,and 60 questionnaires returned at post-therapy,from 30 intervention group participants and 30 control group participants.Baseline scores for SAS and SDS were higher in intervention than control group[(42.0 ±7.7)vs.(36.0 ±6.8),(44.4 ±11.5)vs. (38.7 ±9.0),Ps <0.05],while other itemswere not differ(Ps>0.05 ).Post-therapy,intervention group participants reported significantly scores for anxiety, depression and fatigue compared with controlled group.In the comparison of before-post difference between inter-vention and controlled group,the difference of SAS score,SDS score,role function score and fatigue score showed significant discrepancy,intervention group improve significantly (Ps <0.05 ).Conclusion:Group psychotherapy could improve anxiety and depression,for colorectal cancer patients,and may help to improve quality of life,possi-bly through improving role function and decreasing fatigue symptoms.

Objective To explore the integrity of white matter changes in patients with vascular mild cognitive impairment (VaMCI)based Leukoaraiosis.Methods The patients which appeared white matter hyperintensities in subcortical were performed psychological testing,then 48 VaMCI patients and 18 without cognitive impairment volunteers(NC)were choosed and performed DTI scanning,to determine the white matter’s values of FA and ADC in the following bilaterally symmetrical regions of interest(ROI):entorhinal cortex lobe,hippocampal vault,anterior of corpus callosum,posterior of corpus callosum,inferior frontal lobe,superior temporal lobe and angular gyrus of occipital lobe. Then the differences of the data of DTI between two groups and the relevance between neuropsychological score and DTI’s data were analysed.Results ADC values were significantly higher of VaMCI group in the left inferior frontal lobe,left anterior of corpus callo-sum,left hippocampus vault and right angular gyrus compared with NC group(P <0.05),and in the left hippocampus ADC values and MoCA scores was negatively correlated(r=-0.34,P =0.02).There was no significant difference of FA values between groups. Conclusion The ADC values in many cognitive related areas was reduced in VaMCI patients.
