AIM:Chronic heart failure (CHF), caused by ischemic cardiomyopathy (ICM) and nonischemic cardiomyopathy (NICM), is among the leading causes of mortality and morbidity worldwide .Low-density lipoprotein receptor-related protein 6 (LRP6) plays a criti-cal role in regulating Wnt signaling .Dysregulated Wnt signaling contributes to high incidence of arrhythmias .Thus, there might be an association between genetic variations of LRP6 and sudden cardiac death ( SCD) .The objective of the study was to examine the associ-ation between common variants of LRP6 and prognosis of CHF patients .METHODS:From July 2005 to December 2009, patients with CHF referred from 10 hospitals and participants without structural heart disease in China were undergone a prospective study .The sin-gle-nucleotide polymorphism rs 2302684 was selected to evaluate the effect of LRP6 polymorphisms on the survival of the patients .RE-SULTS:A total of 1 887 patients (1 437 with CHF and 450 in the control group)were finally enrolled for the analysis.During a medi-an follow-up of 61 months, a total of 546 (38.00%) patients died, including 201(36.81%) cases with SCD and 345 (63.19%) ca-ses with NSCD.No end point event occurred in the control group .Patients carrying A allele of rs2302684 had increased risks of all-cause death (P<0.01) and SCD (P<0.01).After adjusted for the other risk factors , the associations remained significant in all-cause death (P<0.01) and SCD (P<0.01).In patients with CHF caused by ICM , those carrying A allele of rs2302684 also had in-creased risks of all-cause death (P<0.01) and SCD (P<0.01).After adjusted for the other risk factors , the associations remained significant in all-cause death (P<0.01) and SCD (P<0.01).However, there was no association between A allele of rs 2302684 and prognosis in patients with CHF caused by NICM .CONCLUSION:The SNP rs2302684 T>A in LRP6 is associated with an increased risk of all-cause death and SCD in patients with CHF in Chinese Han population , and the association is more prevalent in patients with CHF caused by ICM.Thus, LRP6 might be added as a novel predictor of SCD and could provide an attractive and direct therapeutic target in SCD prevention .

OBJECTIVETo observe the differences in onset time and the overall efficacy of the acupuncture therapy of dredging Governor Vessel and regulating mentality combined with fluoxetine and the fluoxetine for post-stroke depression(PSD).
METHODSSixty-three patients were randomly divided into an acupuncture intervention of dredging Governor Vessel and regulating mentality group(acupuncture and medication group, 33 cases) and a control group (medication group, 30 cases). In the medication group, 20 mg fluoxetine was used by oral administration, once a day at 7:00 in the morning, continuously for 4 weeks. In the acupuncture and medication group, based on the oral administration of fluoxetine, the acupuncture intervention of dredging Governor Vessel and regulating mentality was applied mainly at Baihui(GV 20), Fengfu(GV 16), Shenting(GV 24), Shuigou(GV 26), Dazhui(GV 14) and Shendao(GV 11), once a day, 6 times a week, continuously for 4 weeks. Twenty-four items in Hamilton Depression Scale(HAMD), modified Edinburgh Scandinavia Stroke Scale(MESSS) and activity of daily life scale(ADL, Barthel index, BI) were used before and after 2-week and 4-week treatment. The efficacy was compared between the two groups.
RESULTSAfter 2-week treatment, the HAMD score and the MESSS score in the acupuncture and medication group were obviously decreased and the BI score was apparently increased(all P<0. 01). In the medication group, however, the score of every scale was not statistically different from that before treatment(P'>0. 05). After 4-week treatment, HAMD scores and MESSS scores in the two groups were obviously decreased and the BI scores I were apparently increased(all P<0. 01). After 2-week and 4-week treatment, the HAMD scores and the MESSS scores in the acupuncture and medication group were lower than those in the medication group and the BI scores were higher than those in the medication group(P<0. 01, P<0. 05). The total effective rate of anti-depression (97. 0%, 32/33) the total effective rate of nerve function impairment(90. 9%, 30/33) and the total effective rate of daily life activity(97. 0% 32/33) in the acupuncture and medication group were better than 80. 0% (24/30), 80. 0%(24/30), 83. 3%(25/30) in the medication group(all P<0. 05).
CONCLUSIONThe acupuncture therapy of dredging Governor Vessel and regulating mentality could reduce the onset time of anti-depression medicine treatment of PSD and enhance the overall efficacy. Therefore, it enhances the clinical compliance.

To investigate the ability of composite graft of osteobalsts and deproteinized bone-titanium mesh (DPB-TM) scaffold to repair cranial bone defect. 30 rabbits were randomly divided into 3 groups. The passage 3 fetal rabbit osteoblasts were seeded into porous DPB-TM scaffolds at the density of 5 x 10(6) ml(-1) as the experimental group. The same defects were respectively reconstructed by DPB-TM or osteoblasts as the control groups. After 12 weeks, the result was evaluated by three-dimensional computed tomographic scanning, gross inspection, scanning electron microscopy, histological examination and mechanics test, respectively. In the experimental group, bone trabecula was observed to pass the defect and interface was mixed. No demarcation between the region of the bone defect and the normal bone was observed. There was plenty of new bone on the scaffold. Part of the scaffold was absorbed. In view of mechanics, the intensity of artificial bone (18.93+/-1.12 MPa) was higher than that of normal bone (16.96+/-1.60 MPa) (P<0.05). In the control groups, only fibrous tissue was observed in the defect region, there was no new bone formation. The tissue engineering bone constructed by osteoblasts and DPB-TM scaffold can be applied to the repair of bone defect.
