Objective\ Treatment of spondylolisthesis using freeze dried femoral ring allografts plus morselled cancellous autografts (called as composite cortical ring) by anterior lumbar interbody fusion (ALIF). Methods\ Fourteen patients were treated by this procedure, there were six males and eight females. The age of the patients range from 40 to 56(average 46). Ten segments were of grade Ⅱspondylolisthesis, five segments were of gradeⅠ. Ten patients were treated with RF as internal fixation, four patients with short Harrington rod as internal fixation. Results\ The fusion rate and clinical results of ALIF were analyzed by comparing the findings on the X-ray films taken preoperatively and 6 months postoperatively as well as by JOA score. The fusion rate of 15 segments of 14 patients(two segments of 1 patient was fused) is 85.7%, the average improvement rate of JOA score is 73.3%at an average follow up of 26.6 months. Conclusion\ ALIF with composite cortical ring could successfully restore the spinal structure, maintain the interspace height distracted intraoperatively, obtain high fusion rate and excellent clinical results.\;

Objective To analyze the quality of life (QOL) of mothers of children with cerebral palsy and it's influencing factors.Methods The QOL of 123 children with cerebral palsy and their mothers was assessed a 36-item short form health survey (SF-36) and basic questionnaires combined with interviews.The factors influencing QOL were analyzed with t-tests and one way analysis of variance,and multiple regression analysis was used to determine the main influencing factors.Results Scores on all of the SF-36 items were much lower for mothers of children with cerebral palsy than for mothers of normal children.Average scores in the domains of emotional health,general health and vitality were the lowest (55.28,60.49 and 65.26 respectively).Correlation analysis showed that general health,physical function and role emotions were positively correlated with the child's age.All domains except pain were negatively correlated with the child's condition.Social functioning was positively correlated with the mother's age.The general health,role emotional,social function,and mental health scores were all negatively correlated with the mother's education level.Univariate analysis showed that the child's age and condition,the mother's education level and occupation,and the father's occupation all significantly predicted the mother's QOL.Multivariate regression analysis confirmed that the child's age and the father's occupation had significant predictive power.Conclusions The QOL of the mother of a child with cerebral palsy is mainly influenced by the child's age and condition,the mother's education level and occupation,and the father's occupation.Comprehensive and effective measures should be taken to improve the QOL of mothers of children with cerebral palsy and to improve the efficacy of rehabilitation for children with cerebral palsy.

Objective To explore the clinical characteristics and causes of death in patients with acute heart failure at aged 75 and over.Methods The prospective study collected 175 patients with acute heart failure from January 2012 to December 2014.They were divided into ≥75 years old group and＜75 years old group and the general clinical data were recorded.Follow-up was performed mainly by telephone with supplemented hospitalization follow-up and outpatient follow-up.Survival rates were assessed by Kaplan-Meier method.The survival rate difference between the two groups was compared using the log-rank test.Multivariate Cox proportional hazards regression analysis was used to determine the independent risk factors for death.Results The proportions of ischemic heart disease,hypertension and old myocardial infarction were higher in the elderly group than in the young group with a higher proportion of male,diabetes and body mass index in ＜75 years old group.Elderly group had a higher level of left ventricular ejection fraction(LVEF)and a lower level of total cholesterol,triglycerides and low density lipoprotein cholesterol(LDL-C).Kaplan-Meier curves showed that allcause mortality(x2 =4.005,P =0.045) and non-cardiovascular mortality(x2 =4.418,P =0.041) were significantly higher in the elderly group than in the younger group,whereas cardiovascular mortality had no significant difference between the two groups (x2 =0.754,P =0.385).In patients with noncardiovascular mortality,12 cases (63.2％)died of pulmonary infection in elderly group,3 cases(25.0％) died of lung infection in younger group,and the difference was statistically significant between the 2 groups (x2 =4.288,P =0.038).Multivariate Cox proportional hazards regression analysis showed that age≥75 years was an independent predictor for both non-cardiovascular mortality [HR(95％CI):2.71(1.50-6.55),Wald x2 =2.266,P=0.038]and all-cause mortality[HR(95 ％CI):1.75(1.28-3.13),Wald x2 =2.914,P=0.026]in patients with acute heart failure.Conclusions Age ≥75 years is an independent risk factor for all dead patients with acute heart failure and noncardiovascular death,but it is not the independent risk factors for cardiovascular death,which is of great significance to establish a more rational treatment strategy for senile heart failure.

Objective To study the role of mutation of p300/CBP gene in the development of human gastric carcinoma (GC) . Methods Mutations analysis of the p300/CBP gene were carried out in 30 fresh GC samples using a combination of polymerase chain reaction single-strand conformation polymorphism (PCR-SSCP) and DNA sequencing,and compared with gastric mucosa distance from the GC. Results p300/CBP genes mutations were detected in 4 of 30 fresh GCs. All the mutation were point mutations, including T to G in nucleotide 4741, 4773,4847 and 4881 in genomic DNA of p300. The mutation site was in the non-coding area in nucleotid 4741;whereas in the others were in the coding area, leading to the change of the amino acids, induding Ser to Arg in nucleotide 4773, Val to Ala in nucleotide 4847 and 4881, respectively. Of the 30 patients, 4 cases with the single site mutation were discovered, 2 cases had the first two sites mutation, while the others had all the four sites mutation. Conclusions Two to four poiuts mutation of p300/CBP gene are presented in GC.

Objective To identify the expression of PTEN ,vascular endothelial growth factor(VEGF)and (matrix) metalloproteinase 9(MMP-9) in gastric carcinoma and its relationship to the biological behavior of (gastric) carcinoma. Methods The expression of PTEN ,VEGF and MMP-9 in 71 cases of gastric carcinoma tissue and 37 cases of gastric mucosa distant from carcinoma were detected by streptavidin peroxidase (immunohistochemistry). Results The expression of PTEN in gastric carcinoma tissues(71.8%) was (significantly) lower than its expression in gastric mucosa distant from carcinoma(100%)(P0.05).The expression of VEGF in gastric carcinoma(62.5%) was sigificantly higher than in gastric mucosa distant from carcinoma(29.7%)(P0.05).The expression of MMP-9 in gastric (carcinoma)(69%) was significantly higer than in gastric mucosa distant form carcinoma(40.5%)(P0.05).The expression of PTEN in gastric carcinoma was inversely correlated with expression of VEGF and MMP-9(P

Objective To investigate the effect of TGIF on apoptosis of TGF-?-induced gastric canceer cell.Methods After TGIF was stably transfected into gastric cancer cell line BGC823,apoptosis was examined with flow cytometry,and the expressions of TGIF,caspase8 and caspase9 were analyzed with Western blot.Results The apoptosis rate of BGC823 cells with the treatment of TGF-? obviously increased,and was accompanied by activation of caspase9 but not caspase8.Moreover,compared with controls,pcDNA3.1-TGIF-transfected BGC823 cells significantly decreased the sensitivity of TGF-?-induced apoptosis.Conclusions TGF-? induced the apoptosis of gastric cancer cell BGC823 via caspase9 pathway;furthermore,TGIF could inhibit TGF-?-induced apoptosis.

Objective: To evaluate the anthracyclines-induced cardiotoxicity in patients with early-stage breast cancer. Methods: This retrospective study analyzed data of 64 patients (aged from 36 to 59 years old) with early-stage breast cancer after surgery. Patients were divided into ACT group (n=21), FAC group (n=19) and EC group (n=24). The NCI CTC 4.0 scores was used to evaluate the side effects at the time of 2 weeks, 4 weeks and 6 weeks after chemotherapy. Meanwhile, the level of cTnT, the incidence of abnormal electrocardiogram (ECG) and left ventricular ejection fraction (LVEF) were used to evaluate the anthracyclines-induced cardiotoxicity, the follow-up observation points were as follows: at the acute cardiotoxicity (time A), subacute cardiotoxicity (time B), 24 months after chemotherapy (time C), 36 months after chemotherapy (time D), 48 months after chemotherapy (time E), 60 months after chemotherapy (time F). The 3-years and 5-years overall survival and progress free disease survival among three groups were compared. Results: The ages, clinical stage, the size of tumor, axillary lymph node positivity and Eastern Cooperative Oncology Group Scores were similar among three groups (P>0.05); the incidence of side effects level 4 was 0. The levels of cTnT in the three groups were significantly lower than those at the baseline and time points C, D, E and F (all P<0.05), and the levels of cTnT were significantly higher in EC group than in FAC and ACT group at the time points B, C, D, E and F (P<0.05); however, the incidence of abnormal ECG and LVEF was similar among the 3 groups (P>0.05). The 5-year overall survival was 95.2% (20/21) ,100% (19/19) and 95.8% (23/24) in ACT group, FAC group and EC group, respectively; 5-year progress free disease survival was 95.2% (20/21) ,94.7% (18/19) and 91.7% (22/24) in ACT group, FAC group and EC group, respectively (P>0.05) . Conclusions Patients with early-stage breast cancer after surgery could tolerate the anthracyclines-induced cardiotoxicity. Three chemotherapy schemes of ACT, FAC and EC, especially the EC protocol, could affect the myocardial damage. However, outcome is comparable among patients treated with above chemotherapy schemes in this patient cohort.

Objective To investigate the effect of knockdown or overexpression of G6PD on proliferation, growth and migration of human hepatocellular carcinoma cell PLC/PRF/5. Methods Lentivirus-mediated knock-down or overexpression of G6PD was achieved in human hepatocellular carcinoma cell line PLC/PRF/5. RT-PCR and Western blotting assay were used to detect the overexpression or knockdown of G6PD.Cell proliferation and mi-gration curves were recorded by real-time cell analysis system(RTCA),the cell proportion in the DNA replication phase can be directly displayed with EDU experiment,cell growth ability was detected by colony forming assay. Results The doubling time of cells in G6PD knockdown group was longer than that of the control group,and the cell growth rate decreased significantly,the proportion of cells in proliferative phase(43.2%)was lower than that in the control group,but the rates colony formation and migration were significantly decreased(P<0.05,respective-ly),and the migration curves separated apparently.While no significant differences in proliferation,growth and mi-gration of PLC/PRF/5 cells were found between the over-expressed strain and the control group. Conclusion The reduction of G6PD expression in HCC cells inhibits the proliferation and growth of HCC,which may lay a foun-dation for the further study of the pathogenesis and treatment of HCC.

Objective: To investigate the clinical efficacy and outcome determinants in cardiac arrest patients secondary to acute myocardial infarction treated with extracorporeal membrane oxygenation (ECMO) and percutaneous coronary intervention (PCI). Methods: The clinical data of 27 patients hospitalized from January 2014 to March 2017 in 3 hospitals were retrospectively analyzed. The clinical data of the surviving group (12 cases) and the death group (15 cases) were compared and the outcome determinants were explored. Results: Twenty seven patients were successfully treated with coronary angiography and emergency PCI under ECMO assistance, and the successful procedure rate was 100%. The survival rate was 44.4% (12/27). There was no significant difference in gender, age, body weight, myocardial infarct location, past disease history and smoking status between the two groups (all P>0.05). Traditional cardiopulmonary resuscitation time was significantly longer, the CCU hospitalization time was significantly shorter, the number of diseased vessels was significantly higher, and the prevalence of distribution of blood vessels in left main stem was significantly higher and mean artery pressure at 24 and 48 hours post ECMO was significantly lower in the death group than in survival group (all P<0.05). Multiple logistic regression analysis showed that left anterior descending artery lesion, higher number of lesion vessels, longer traditional cardiopulmonary resuscitation time, longer time interval between cardiac arrest and ECMO placement were related increased risk of death post ECMO and emergency PCI in this patient cohort(OR=1.316, 95%CI 1.217-5.792, P=0.002; OR=1.238, 95%CI 1.107-4.961, P=0.000; OR=1.712, 95%CI 1.136-3.973, P=0.001; OR=1.629, 95%CI 1.132-4.521, P=0.000, respectively), while higher mean artery pressure at 48 hours post ECMO was related with reduced risk of death post ECMO and emergency PCI in this patient cohort(OR=0.672, 95%CI 0.326-0.693, P=0.001). Conclusions ECMO combined with emergency PCI can improve the success rate of traditional cardiopulmonary resuscitation in patients with cardiac arrest secondary to acute myocardial infarction. Left anterior descending artery lesion, number of lesion vessels, traditional cardiopulmonary resuscitation time, time interval between cardiac arrest and ECMO placement and mean artery pressure at 48 hours post ECMO are outcome determinants post ECMO and emergency PCI in this patient cohort.
