Chest wall reconstruction is a key approach to restoring the structure and function of the defective chest wall after tumor excision. While autologous flaps have been ideal materials for soft tissue reconstruction,the optimal skeletal reconstructive material still remains controversial. Currently,besides autologous bones,non-biodegradable materials have been used widely,which offer sufficient strength and stability but with some inevitable complications. Many studies have explored the clinical applications of biodegradable materials and the improvements in their characteristics,and some of these materials may be clinically feasible. This article reviews the recent advances in the applications of reconstructive materials.

However,body contouring is required to solve skin problems associated with massive weight loss after bariatric surgery. This article reviews the indications,importance,and postoperative complications of body contouring after bariatric surgery.
RESUMO
<p><b>OBJECTIVE</b>Clinical application of autologous fat grafting (AFG) is quickly expanding. Despite the widely acceptance, long-term survival rate (SR) of AFG remains a question not yet solved. Meanwhile, although rare, severe complications related to AFG including vision loss, stroke even death could be seen in the literature.</p><p><b>DATA SOURCES</b>A comprehensive research of PubMed database to June 2013 was performed according to guidelines of the American Society of Plastic Surgeons Fat Graft Task Force Assessment Methodology. Articles were screened using predetermined inclusion and exclusion criteria.</p><p><b>STUDY SELECTION</b>Data collected included patient characteristics, surgical technique, donor site, recipient site, graft amount, and quantified measurement methods. Patient cohorts were pooled, and SR was calculated. All the severe complications were also summarized according to the different clinical characteristics.</p><p><b>RESULTS</b>Of 550 articles, 16 clinical articles and 10 animal studies met the inclusion criteria and provided quantified measurement methods. Totally, 596 patients were included. SR varied from 34% to 82% in breast and 30-83% in the facial area. Nude mice were applied to investigate human fat grafting SR (38.3-52.5% after 15 weeks). Rabbits were commonly used to study animal AFG SR (14.00-14.56% after 1-year). Totally, 21 severe complications were reported, including death (2), stroke (10), vision loss (11, 8 of which accompanied with stroke), sepsis (3), multiple abscess (1) and giant fat necrotic cyst (2). Ten of these complications happened within 10 years.</p><p><b>CONCLUSIONS</b>There is no unified measurement method to evaluate fat graft SR until now and no clinical evidence to show better SR according to different donor and recipient cite. Body mass index change between pre- and postoperation may be the bias factor in evaluating fat SR. Fat embolisms of the ophthalmic artery and the middle cerebral artery are the most severe complication of AFG and still lack of effective treatment.</p>

RESUMO
The current pharmacotherapy is inadequate in preventing the progression of ventricular remodeling and congestive heart failure. Cellular cardiomyoplasty, through cell transplantation or regeneration of cardiomyocytes is a potential therapeutic approach to prevent left ventricular remodeling and the development of congestive heart failure after myocardial infarction. Recent research has focused on stem cells, which are undifferentiated pluripotent cells and can differentiate into a wide variety of cells including cardiac myocytes and endothelial cells. The majority data on stem cell transplantation were preclinical animal studies, all showing that stem cell therapy may replace lost heart muscle (myogenesis) and enhance cardiovascular revascularization (angiogenesis and vasculogenesis). These findings have been rapidly applied to human trials, but there were many questions remain to be solved. Although the results are interesting and safe, early phase Ⅰ clinical studies are small in scale and very preliminary. Data from large, randomized controlled trials are needed to confirm the short- and long-term effects of cellular cardiomyoplasty.
RESUMO
Objective To determine the prevalence of renal artery stenosis (RAS) and the efficacy of percutaneous transluminal renal angioplasty (PTRA) and stenting in patients with documented coronary artery disease.Methods Selective renal artery angiography or abdominal digital subtraction angiography was performed immediately after coronary angiography to detect and quantify RAS in 200 consecutive patients with known or suspected coronary artery disease. Eight severe stenotic renal arteries in 7 patients were treated with PTRA and stenting. All the lesions are considered to be atherosclerotic. Results RAS (defined as ≥50% diameter stenosis) was detected in 21 of 200 patients (10.5%) and 19 of 99 patients with coronary artery disease (19.2%) who had at least one coronary artery of ≥50% diameter stenosis. Procedure success rate was 100% in the 7 patients received PTRA and stenting. Blood pressure control improved in 74.1% patients with hypertension. Angiographic follow up was done in 3 patients in 3 to 9 months and no restenosis was found in the vessels.Conclusions It is necessary to routinely perform RAS for the patients with coronary artery discase undergoing coronary angiography to identify RAS, especially in those associated with hypertension, so as to diagnose and treat RAS in early stage. PTRA and stenting carries high success rate and appears to be an effective and safe treatment for RAS.
RESUMO
Objective:To observe the effect of percutaneous tr ansluminal coronary angioplasty (PTCA) on coronary circulating tumor necrosis fa ctor-α (TNF-α) activity. Methods: Plasma TNF-α levls were measured with radioimmunoassay and bioactive assay respectively. Result s: Plasma TNF-α activity in femoral artery (AO) was significantly incr eased immediately after PTCA ［(15.86±3.75) U/ml vs （41.32±4.36） U/ml， P<0.01］, and plasma TNF-α activity in coronary sinus was remarkably incre ased immediately after PTCA ［(16.72±4.14） U/ml vs （65.61±6.25） U/ml, P<0.01］. There was no change in plasma TNF-α activity in AO 24 h after PT CA ［(18.32±5.12） U/ml vs （15.86±3.75） U/ml, P>0.05］. Conclu sion: The increase in plasma TNF-α activity after PTCA may be associat ed with the injury of coronary artery caused by PTCA, suggesting that TNF-α ma y be involved in the coronary occlusion and the development of coronary restenos is after PTCA.
RESUMO
Objective: To observe the effects of angina pector is on severe ventricular arrhythmia and QTd in patients with first acute myocard ial infarction(AMI). Methods: One hundred and eight-four cases of first AMI were divided into 2 groups: PA group, angina pectoris occurred with in 24 h before AMI onset (n=58), NPA group, no preceeding angina pectori s occurred (n=126). Occurrence of complications and QTd were investigated du ring hospitalization. Results: The basic clinical characteristic s, coronary risk factors, medication before infarction, treatments after admissi on with antiarrhythmic agents, site of infarction, successful rate of thrombolys is and peak CK, CK-MB were not statistically different. Early QTd in PA group and NPA group were (56.22±18.40) ms vs (84.45±21.90) ms, respectively, P <0.05, late QTd in PA group and NPA group were (50.67± 16.34) ms vs (64.1 8(16.41) ms, respectively, P<0.05. Comparison with NPA group, incidence of severe ventricular arrhythmia, heart failure, cardiogenic shock and rate of car diac mortality in-hospital was lower in PA group. Conclusion: P reinfarction angina pectoris can significantly reduce the incidence of severe ve ntricular arrhythmia and QTd in the patients with first AMI, sugges ting that these favorable effects might be associated with protective effects of ischemic preconditioning on myocardium and ventricular pump function and improv ement of repolarizative asynchronism in ventricular myocardium.
RESUMO
Objective: To investigate the effects of pravastatin o n atherosclerotic plaque and cardiovascular events. Methods: Fifty- seven patients with coronary artery disease (44 male and 13 female, 58.4±11.3 y ears) were randommized into pravastatin and control groups. The patients in prav astatin group were administered 10 mg of pravastatin from the night of coronary angiography day. After 7.3 months (mean) of follow-up, plasma lipid parameters and coronary angiograph were repeated. Results: (1) A favorable effect on plasma lipid parameters was found. After administration, total choles terol(TC), low density lipoprotein cholesterol (LDL-C) and triglyceride(TG) red uced by 15.0% (P<0.01), 18.0% (P<0.01) and 6.0%, respectively. High den s ity lipoprotein cholesterol(HDL-C) increased by 10.6%. However, in control grou p, TC and LDL-C showed a tendency to reduce, but no significant difference was found between those of pre- and post-administration. (2)There was no significa nt difference in luminal diameter between pre- and post-administration in both groups. (3) Cardiovascular events in pravastatin group was significantly lower than those in control (P<0.05). (4) Pravastatin had no significant effect on HR, BP and left ventricular ejection fraction in both groups. Conclusio n: Pravastatin can stabilize coronary atherosclerostic plaque and reduce the incidence of cardiovascular events by improving plasma lipid parameters.
RESUMO
Objective: To determine the eff ect of probucol on adhesion of human monocytic line THP-1 induced by oxidized low density lipoprotein (oxLDL). Methods: THP-1 cells were induced by oxLDL in vitro. The CD11b, CD54 expressions and adhesion to human umbilic al vein endothelial cells (HUVEC) were measured after treatment with probucol at different concentrations by flow cytometry and β-nitrophenyl N-acetyl-β-D -glucosminide test. Results: Probucol inhibited the adhesion of oxLDL-induced THP-1 cells to HUVEC and down regulated the expression of CD11b in a dose dependent manner (P<0.01), but there was no inhibition on exp ression of CD54. Conclusion: Probucol can inhibit adhesion and a ggregation of monocyte-macrophages to endothelium in circulation, and may have anti-inflammatory action.
RESUMO
Objective: To investigate the relationship between serum HGF levels and clinical severity of essential hypertension (EH). Methods: The serum HGF concentrations of 44 patients with EH were measur ed by ELISA. Results: The serum HGF levels in patients with EH w ere higher than that in control. Furthermore, the serum HGF levels of EH patient s with coronary atherosclerosis (CAS) were significantly higher than those of EH patients without CAS ［(920.8±250.0） pg/ml vs （747.9±132.1） pg/ml, P <0.01］ or control ［（643.8±98.2） pg/ml, P<0.01)］.The changes of HGF l evel were correlated with the clinical courses (r=0.63, P<0.01) and stag es (r=0.69, P<0.01) of hypertension. Conclusion: HGF may be considered as a new index for the severity of hypertension and an useful bio chemical parameter for estimating the development of atherosclerosis.
RESUMO
Objective: To assess the effect of balloon angiopl asty on circulating endothelin (ET) and TNF-α levels and tissue endothelin in experimental atherosclerosis in rabbits. Methods: After 20 New Z ealand rabbits had a high cholesterol diet for at least 8 weeks, successful ball oon angioplasty was performed in rihgt iliac arteries in 18 rabbits. Circulatin g levels of ET and TNF-α were measured before as well as immediately and 24 h after balloon angioplasty. Tissue endothelin immunoreactivity in atherosclerotic iliac artery wall after balloon angioplasty was assessed by immunohistochemica l technique. Results: Plasma levels of ET and TNF-α were signi ficantly increased immediately after ballon angioplasty (76.40±13.58)pg/ml vs (92.67±11.38) pg/ml and (31.35±6.23) U/ml vs (56.26±7.37) U/ml, resp ectively (P<0.05) .There was no change in plasma ET and TNF-α levels 24 h after balloon angioplasty (77.13±12.87) pg/ml vs (76.40±13.58) pg/ml and (33.41±6.79) U/ml vs (31.35±6.23) U/ml， respectively (P>0.05). T issue endothelin immunoreactiuvity was markedly increased in right iliac artery wall after balloon angioplasty than that in opposite iliac artery wall. Conclusion: The increase of plasma ET, TNF-α levels and tissue ET-IR in iliac artery wall after balloon angioplasty may be associated with the injury of l ocal vascular intima, suggesting that ET and TNF-α may take part in the corona ry constriction and the development of coronary restenosis after percutaneous tr ansluminal coronary angioplasty.
