Objective To evaluate the effect of off-pump coronary endarterectomy (CE) plus off-pump coronary artery bypass grafting (off-pump CABG) on patients with chronic total occlusion (CTO) combined with diffuse distal atherosclerosis. Methods From October 2006 to August 2009,65 CTO patients with 176 angiographically confirmed vascular stenosis or occlusive lesions, 70 of which were complete occlusion, underwent off-pump CABG. During the operation, diffuse intimal thickening distal to occlusive lesion was found, and blood flow of the bridges was unfavorable.Results Therefore endarterectomy was performed, followed by CABG. The blood flow in the bridges were 2-10 ml/min versus 14-37 ml/min before versus after endarterectomy. Pulsatility index (PI) was 5.1-15.6 versus less than 5 before versus after endarterectomy. Left ventricular ejection fraction was also improved significantly [before operation: (0.47±0.12)%, after operation: (0. 52±0.15)%, t=2.17, P<0.05]. Peri-operative myocardial infarction occurred in 2 cases, but without significant cardiac homodynamic changes. And 23 patients underwent coronary angiography to evaluate graft patency 3-18 months after operation, all of them had favorable blood flow. Conclusions It is feasible to perform off-pump CABG plus coronary endarterectomy for patients of chronic coronary total occlusion combined with diffuse distal atherosclerosis. This treatment is safe and effective.

OBJECTIVETo compare clinical effects between percutaneous compressing plating (PCCP) and proximal femoral nail antirotation (PFNA) for the treatment of patients with intertrochanteric fracture with risk external wall.
METHODSFrom September 2007 to June 2010, 43 patients with intertrochanteric fracture with risk external wall were treated by PCCP or PFNA according to different kinds of internal fixations. There were 22 cases in PCCP, including 9 males and 13 females with an average age of 68.4 (ranged, 60 to 86) years old, and 13 cases with type A2.2 and 9 cases with type A2.3; while 21 cases in PFNA, including 7 males and 14 females with an average age of 67.7 (ranged, 57 to 93) years old, and 10 cases with type A2.2 and 11 cases with type A2.3. Blood loss, operation time, hospital stay, fracture healing time, complications and Harris score after 1 years' following-up were observed and compared.
RESULTSAll patients were followed up for 12 to 22 (means 18.4) months, and all patients were obtained fracture healing, and recovered walking ability as before injury. There were no significant differences in blood loss, operation time, hospital stay, fracture healing time, complications and Harris score after 1 years' following-up (P>0.05). One case occurred displacement on the top of greater trochanter, and 1 case injuried weakness of hip abduction. One case occurred screw breakage in PCCP, while 1 case occurred hip joint pain in PFNA.
CONCLUSIONBoth of PCCP and PFNA in treating patients with intertrochanteric fracture with risk external wall can receive good clinical effects, while the effects and therapy strategy for displacement of bone on the top of lateral wall should further study.

Objective To propose a new blood purification modality-hemodialysis with plasma- based dialysate (HD-PBD) plus high volume hemofiltration (HVHF) for patients with liver failure, and to evaluate the effect of this treatment on plasma cytokines.Methods Twelve patients with liver failure were included in this study.All patients received HD-PBD therapy in the first 6 hours,and then were treated with HVHF for 24 hours with the same filter (AV600).The levels of TNF-?,IL-1?, IL-6 and IL-8 in plasma before and after HD-PBD plus HVHF for 6 and 24 hours were examined respectively by ELISA,and changes of clinical parameters were observed at the same time point. Serum bilirubin,total bile acids (TBA),serum ammonia,blood urea nitrogen (BUN) and serum creatinine (Scr) were detected before and after treatment.Arterial blood gas analysis and the concentration of electrolytes were monitored before and after treatment.Results (1)HD-PBD for 6 hours was more effective than HVHF for 24 hours in removal of serum bilirubin and TBA(P<0.05). (2)Serum ammonia,BUN,Ser,arterial blood HCO_3~-,PCO_2,PO_2 and electrolytes did not show significant difference before and after HD-PBD (P>0.05),but these parameters significantly changed before and after HVHF (P<0.05).(3)The average level of serum bilirubin was sharply decreased after HVHF for 24 h following HD-PBD(P<0.05).(4)After HD-PBD plus HVHF,there was a marked reduction of the plasma levels of TNF-?,IL-6 and IL-8.Conclusions HD-PBD plus HVHF,a newly proposed modality for patients with liver failure,can effectively decrease serum bilirubin,TBA,BUN,Scr,ammonia and cytokines,and adjust water-electrolyte as well as acid- alkali balance.It is a low-cost,safe,simple and convenient therapy.

Objective The present study was to explore association of PvuⅡand XbaⅠpolymorphism in ER-?gene with genetic susceptibility for breast cancer without BRCAl/2 gene mutation. Methods 113 BRCA1/2 negative hereditary breast cancer patients from independent families and 113 agematched healthy control subjects were analyzed. Genotype analysis was conducted by polymerase chain reaction (PCR) and then DNA direct sequencing. The odd-ratios (OR) and 95% confidence intervals (CI) was calculated by unconditional logistic regression model. Results The frequency of PvuⅡpolymorphism CC(PP) ,CT(Pp) ,TT(pp) genotype in patients was found in 16 cases(14.2% ), 58 cases(51. 3% ) , and 39 cases (34. 5% ). The distribution of AA (xx) , AG (Xx) , GG (XX) genotype of XbaⅠpolymorphism were found in 76 cases ( 67. 2% ) , 34 cases ( 30. 1% ), and 3 cases ( 2. 7% ) among patients. Among premenopausal women, CT genotype of PvuⅡconfered a significantly increased risk for breast cancer compared with CC genotype ( adjusted OR = 2. 07; 95% CI, 0. 68 - 6. 30) ; Carriers of GG of XbaⅠhad a decreased risk for breast cancer (adjusted OR =0. 11; 95 % CI, 0. 01 - 1. 27) compared with AA genotype. Furthermore, combined analysis of two polymorphisms indicated individuals carrying PvuⅡCT and XbaⅠAA genotype were at increased risk for breast cancer as compared with those with PvuⅡCC and XbaⅠGG genotype (Oft = 11.43, 95% CI, 1.12-116.7) among premenopausal women. Conclusions PvuⅡand XbaⅠpolymorphisms in ER-?gene could be a candidate locus for low penetrance breast cancer susceptibility in Chinese population, especially among premenopausal women.

Objective To investigate the correlation between ADAM33 T1, S2 gene polymorphism and Bronchial asthma risk in china. Methods We retrived the relevant published studies about ADAM33 T1, S2 gene polymorphism and bronchial asthma risk. Then we divided the population into Chinese and other Asian population. Odds ratio (OR) of Case group and control group was selected as the effect index. Stata 11.0 software was used to calculate heterogeneity test, ORs and 95%CI of two areas, and gave the forest plot and funnel plot of meta results. Results A total of 27 studies were included in this analysis,18 studies in ADAM33 T1 site were 3881 cases in case group, and 3780 cases in control group;and 14 studies in ADAM33 S2 site were 3222 cases in case group, and 3513 cases in control group. Additive model, dominant model, recessive model of ADAM33 T1 in Chinese had association with the susceptibility of bronchial asthma. The results were OR=1.488, 95% CI:1.002-2.167 in Additive model, OR=1.619, 95%CI:1.059-2.475 in dominant model;OR=2.523, 95%CI:1.910-3.333 in recessive model. Three models of ADAM33 T1 in other Asian country had no association with the susceptibility of Bronchial Asthma. Three gene model of ADAM33 S2 in Asian had no association with bronchial asthma susceptibility. Except ADAM33 T1 polymorphism in recessive model, other mode of T1, S2 had no publication bias in Chinese population. Conclusion There are association between ADAM33 T1 gene polymorphism and bronchial asthma, but ADAM33 S2 gene polymorphism and bronchial asthma have no association in Chinese population.
