Objective To study a minimally invasive surgical procedure for coronary artery bypass grafting (GABG). Methods 23 patients, aged from 45 to 73 years old, undervent off-pump coronary artery bypass grafting (OPCABG) according to Octopus procedure from December 1999 to Auguest 2001. In the present study , more than 3 vessels were involved in 19 patients; 2 vessels involved in 3 cases and 1 vessel involved in one case. The grafted arteries included left anterior descending branch (LAD)(23); circumflex(CX)(15); right coronary artery(RCA)(14); ramus intermedius(RUM)(8); and posterior descending artery(PDA) (8). The types of grafts were left internal mammary artery (LIMA)(20) and saphenous vein grafts(SVG)(48). Results None of the patients was managed by means of cardiopulmonary bypass. All survived without angina pectoris. MRI showed that all the conduits were patent postoperatively. Conclusions OPCABG by Octopus procedure can be used in multiple vessel coronary bypass including CX and PDA. The patency rate is similar to that of the conventional technique. The mortality rate and occurrence of complications is low compared with those of the conventional technique . In addition, medical cost is lower. So This procedure is both safe and cost-effective, and is of value in clinical practice.

Objective To investigate the value of parametric imaging of CEUS in uterine fibroids with different signal intensity on T2WI by high intensity focused ultrasound (HIFU),and dynamic vascular pattern (DVP).Methods Totally 16 patients with single uterine fibroids were divided into high intensity group (n=6),isointensity group (n=4) and low intensity group (n=6) according the signal intensity on T2WI before HIFU treatment.CEUS were performed on each patient.SonoLive CAP software was used to analyze the CEUS images and DVP parametric images were reconstructed.Results The maximum intensity,rising time,time to peak and mean transit time were (235.40± 35.46)%,(22.80± 3.16)s,(25.09±2.44)s,(125.78 ± 27.63)s in high intensity group,(71.97± 2.43) %,(24.85±3.22)s,(32.81±3.92)s,(66.52±3.48)s in isointensity group and (16.17±2.83) %,(25.42±2.66)s,(32.82±3.76)s,(64.27±3.33)s in low intensity group.There were statistically significant differences among three groups (all P<0.05).DVP curve was divided into two types:non-washout in high intensity group and cystic type in low intensity group.Conclusion CEUS and DVP imaging can directly quantitively display the difference of blood perfusion among the uterine fibroids with different signal intensity on T2WI which can provide important information for HIFU treatment in uterine fibroids.

Objective To explore the possible risk factors that influence bone mineral density (BMD) in the elderly man with type-2 diabetes.Methods Sixty elderly man with type-2 diabetes were subjected to dual-energy X-ray absorptiometry to evaluate the BMD at lumbar spine ( LS),and femoral neck (FN).Fasting blood and urine samples were taken to check the biochemical levels about bone metablism and blood sugar.The correlations between BMD and other factors were analyzed.Results In this group of patients,the percentage of osteoporosis and osteoponia was 20% and 53.3% in LS or FN site,respectively.Age,Weight,and HbA1c were correlated with BMD.Weight of them had the best correlation with BMD at LS( r =0.254,P <0.01 ),whereas,HbA1c had the best correlation with BMD at FN( r =-0.224,P <0.01 ).Conclusions Age,Weight,and HbAlc c were correlated with BMD of elderly man with type-2 diabetes.

BACKGROUND: Endothelial progenitor calls are the cells that can form new blood vessels in the way of angiogenesis in the body,which updates the conventional theory of angiogenesis, vascular damage and repair after birth and provides new ideas for research and treatment of ischemic diseases.OBJECTIVE: To investigate the effects of dog umbilical cord blood endothelial progenitor call (UCB-EPC) transplantation on angiogenesis after myocardial infarction.DESIGN, TIME AND SETTING: An in vivo cytological experiment was performed at the Laboratory Center of Xinhua Hospital between May 2006 and March 2007.MATERIALS: One full-term pregnant hybrid dog was included for preparation of UCB-EPCs. Thirty-six adult dogs were randomly divided into a cell transplantation group (n = 18) and a model control group (n = 18).METHODS: Acute myocardial infarction model was established in each group by ligation of antedor descending coronary artery.In the cell transplantation group, 2 mL physiological saline containing 5×10<'6> BrdU-labeled EPCs was injected into the coronary artery, while in the model control group, simple physiological saline of the same amount was given. At 1,4, and 8 weeks after transplantation, dogs were sacrificed for harvesting myocardial tissue.MAIN OUTCOME MEASURES: Myocardial infarction was confirmed by hematoxylin-eosin staining. Myocardial angiogenesis was observed by BrdU immunohistochemical staining. The number of infarcted myocardial vessels was calculated by yon Willebrand (vW) factor staining.RESULTS: There was plenty of scar tissue, flbroblasts, and small vessels in the myocardial infarction region. In the cell transplantation group, brown yellow particles (BrdU-positive expression) appeared in some nuclei in small vessels from infarcted myocardium. Newly formed vessels were not found in the model control group. In the cell transplantation group, brown yellow particles (vW factor-positive expression) appeared in the cytoplasm of the vascular endothelial cells in the myocardial ischemia and infarction regions, vW factors were not expressed in the model control group. At 1, 4, and 8 weeks after myocardial infarction,there was no significant difference in vessel counts no matter in myocardial ischemia region or in myocardial infarction region between the call transplantation and model control groups.CONCLUSION: EPCs derived from UCB of pregnant dog can participate in the formation of blood vessels but can not promote angiogenesis after acute myocardial infarction.

Objective To compare the differences in efficacy and safety between transarterial chemoembolization(TACE)com-bined with lenvatinib and camrelizumab(triple therapy)and TACE combined with lenvatinib(double therapy)in intermediate or advanced stage hepatocellular carcinoma(HCC).Methods The clinical data of 145 patients who were diagnosed with HCC and received triple therapy or double therapy were retrospectively collected.The differences of objective response rate(ORR),disease control rate(DCR),median progression-free survival(mPFS),median overall survival(mOS),and adverse events were compared between the two groups.Results The ORR and DCR in 1,3 and 6 months of the triple therapy group were higher than those of the double therapy group,and the differences were statistically significant in 3 and 6 months.The mPFS and mOS of the triple therapy group were higher than those of the double therapy group,and the differences were statistically significant.The Cox proportional hazards model results showed that the therapy methods,maximum tumor diameter and alpha-fetoprotein(AFP)were independent risk factors of progres-sion-free survival(PFS)and overall survival(OS).Besides,Barcelona Clinic Liver Cancer(BCLC)staging was independent risk fac-tor of OS.In terms of adverse events,the incidence of reactive cutaneous capillary endothelial proliferation(RCCEP)and hypothy-roidism in the triple therapy group were higher than those in the double therapy group,and the differences were statistically signifi-cant.Conclusion Compared with double therapy,triple therapy can significantly improve the efficacy of intermediate or advanced stage HCC,prolong patients'PFS and OS,and its safety can be well controlled.
