Objective To analyze the correlation of discomfort experience and factual recollection (FR) in patients of intensive care unit (ICU). Methods Fifty-five ICU patients and 63 ward patients par-ticipated in the study. Standardized questionnaires were used to evaluate all patients" FR and the results underwent analysis. Results The prevalence of recollection of any type of discomfort in the ICU patients was 64%. The presence of an endotracheal tube, pain and hallucinations were identified as sources of dis-comfort.The median score for FR in the ICU patients was 7.25. The median score for FR in the ward pa-tients was 13.50. The difference between them was highly significant (t =3.34, P < 0.01 ). Logistic analysis revealed that discomfort, especially discomfort caused by the presence of an endotracheal tube, pain and hallucinations, was positively related to FR, 0R95%CI (1.2～2.1), P < 0.01. Conclusions The presence of an endotracheal tube, pain and hallucinations were most frequently reported as sources of discomfort in ICU patients and their memory was often impaired. FR and recollection of discomfort appear to be related significantly in ICU patients.

Results:A total of 10 strong association rules are formed. The strong association rules contain some associations between factors and type 2 diabetes. Conclusion: Through the association rules, the initial judgment on the high-risk group of diabetes is simple and accurate.

Objective To investigate the treatment of perinail refracture after surgery of proximal femoral fracture.Methods From January 2010 to January 2015,we treated perinail fractures in 31 patients who had undergone surgery for proximal femoral fracture.They were 11 men and 20 women,with an average age of 75.6 years (range,from 24 to 87 years).On average,their refracture occurred 9.4 months after primary fixation (range,from 3 to 60 months).With reference to the Vancouver classification of peri-prosthestic refractures in the proximal femur and the position and bone quality of perinail refractures,we tried to classify the perinail fractures and chose different treatment protocols accordingly.In our cohort,6 were type A,5 type B,15 type C,and 5 type D.Type A cases were treated conservatively,and types B and C cases with locking compression plate or less invasive stabilization system.In one case of type D,dynamic hip screws were implanted to fixate the femoral neck fracture after removal of the original intramedullary nail,and hip replacement was conducted in the other 4 after removal of the original intramedullary nail.Results The operation time averaged 2.1 hours (range,from 1.6 to 3.0 hours) and intraoperative bleeding 600 mL (range,from 150 to 800 mL) in this cohort.Of them,27 were followed up for an average of 15 months (range,from 12 to 24 months),giving a follow-up rate of 87.1％ (27/31).Six type A fractures obtained bone union after protected weight-bearing walking for 12 weeks.All the 16 fractures of types B and C healed after an average period of 4.2 months (range,from 3 to 6 months).Of the 5 type D fractures,one obtained bone union 12 weeks after change into dynamic hip screwing and 4 had fine functional recovery after hip replacement.No infection,nonunion,or implants failure occurred.Conclusions We have set an exploratory classification system for the perinail refractures at the proximal femur with reference to the Vancouver classification of peri-prosthestic refractures.Our classification can provide effective guidance for the treatment of perinail refracture after surgery of proximal femoral fracture.

Objective To compare the application of three diagnostic criteria for metabolic syndrome(MS) among the elderly in community. Methods 773 elderly people in the community were diagnosed for MS by the Chinese Medical Association Diabetes Society (CDS),International Diabetes Federation (IDF) and revised National Cholesterol Education Prongram-Adult Treatment Panel(ATP Ⅲ* ) criteria,respectively.The diagnosis accordance rates were compared among the different diagnostic criteria. Results The MS prevalence rates in the elderly were 32.5％ (251/773),53.4％ (413/773) and 47.2％ (365/773) according to CDS,IDF and ATP Ⅲ* criteria,respectively and there were significant difference among the criteria (Q=173.10,P＜0.01 ).The MS prevalence was higher in women than in men especially by IDF [57.3％ (284/487)vs.45.1％ (129/286),x2=12.64,P＜0.01]and ATPⅢ* criteria [53.0％(258/487)vs. 37.4％ (107/286),x2=17.52,P＜0.01].The coincidences in the diagnosis of MS were 88.6％ (Kappa=0.773,P＜0.01)using IDF and ATPⅢ * definitions,75.7％ using CDS and ATPⅢ *,and 73.7％ using CDS and IDF.Conclusions The agreement in the diagnosis of MS using IDF and ATPⅢ* definitions is higher than using CDS and IDF or ATPⅢ * definitions.

Objective To assess the prognostic values of the immunohistochemical expression of vascular endothelial growth factor (VEGF) and vascular endothelial growth factor receptor-2 (VEGFR-2) in a cohort of patients with operable advanced laryngeal cancer who have been treated with induction chemotherapy. Methods VEGF and VEGFR-2 expression in the Forty-nine patients was quantified by an enzyme immunosorbent assay in a retrospective series.Results The moderate to high VEGF expression in 34 patients were found and low expression in 15 patients. VEGFR-2 expression was moderate to high in 31 patients and was low expression in 18. The probability of a complete response to induction chemotherapy was significantly higher in patients with none to low VEGF expression.Conclusion VEGF expression seems to be a significant predictor of complete response to induction chemotherapy.

Glioma is the most common intracranial malignant tumor,with high incidence and recurrence rate,high fatality rate and the characteristics of low cure rate.Current treatment is given priority to with surgical treatment,auxiliary comprehensive therapy such as radiotherapy and chemotherapy.Hydrogen peroxide (H2O2) is a intermediate product of the cell oxygen metabolism which is a universal phenomenon in aerobic organisms.H2O2 is indispensable at various stages of tumor cell proliferation,infiltration and metastasis.Studies of the production of H2O2 and its function,the mechanism of apoptosis and the relationship between H2O2 and glioma cells can provide corresponding guidances for looking for a target gene for the treatment of gliomas.

Objective To improve short-and mid-term surgical outcomes ofter the tricuspid ring annuloplasty,and to provide theoretic basis for strategy making among patients with tricuspid regurgitation secondary to left-sided heart diseases.Methods Tricuspid regurgitation secondary to left-sided heart diseases ( including mitral valve diseases and aortic valve diseases) were treated by using tricuspid ring annuloplasty techniques.Patients'age averaged (47.3 ± 12.0) years old,there were a total of 84 female patients(53.2％ ).The average systolic pulmonary pressure was (53.4 ± 19.8) mm Hg.From August 2002 to December 2007,a total of 158 consecutive patients underwent tricuspid ring annuloplasty in Fuwai Cardiovascular disease Hospital.Among this group of patients,there were 66 mild tricuspid regurgitation(41.8％ ),54 moderate(34.2％ ),and 38 severe tricuspid regurgitation(24.0％ ).The average age was (47.3 ± 12.0) years old and female accounted for 53.2％ of the whole cohort.The indications for the tricuspid ring annuloplasty included:moderate to severe tricuspid regurgitation or moderate to severe pulmonary hypertension ( systolic pulmonary hypertension ＞40 mm Hg).In the current study,the ring annuloplasty techniques were modified in the following aspects:selection of undersized ring and partial fixation of tricuspid septal segment.In all the patients,we chose Cosgrove-Edwards ring for tricuspid annuloplasty.The surgical outcomes were evaluated through multivariate regression and Cox analysis.Results Compared with moderate and severe tricuspid regurgitation groups,mild regurgitation group had the smallest ring diameter,mild group ( 38.2 ± 4.9 ) mm,moderate group(47.0 ± 11.6 ) mm,severe group(44.5 ± 8.9) mm,P ＜0.001.No significant differences were noted in terms of ejection fraction among three groups (0.59 ± 0.08,0.59 ± 0.06 and 0.58 ± 0.09,P =0.73 ).Compared with mild and moderate tricuspid regurgitation groups,severe regurgitation group had the highest systolic pulmonary pressure.The diameter reduction was most significant in severe regurgitation group,diameter reduction in mild,moderate and severe regurgitation groups were ( 12.4 ±5.6) mm,(20.8 ± 11.5 ) mm,( 18.6 ± 8.3 ) mm,respectively,P ＜ 0.00 1.An in-hospital death occurred in moderate regurgitation group.157 patients discharged alive.The median follow-up time was 49.1 months.During follow up,three moderate to severe regurgitation occurred,among which one was in moderate regurgitation group,two in severe regurgitation group ( P =0.06).There were three deaths in mild regurgitation group,two in moderate regurgitation group,and four in severe regurgitation group.No significant differences were found in terms of mid-term morality,P =0.10.Conclusion For patients with tricuspid regurgitation secondary to left-sided heart diseases,the mid-term outcomes of modified Cosgrove-Edwards ring annuloplasty were satisfactory.The taking home messages include:positive recommendation for patients with pulmonary hypertension to accept tricuspid annuloplasty,use of undersized ring,and partial fixation of septal segment.
