Objective To investigate the effects of traditional transmyocardial laser revascularization (T-TMLR) and non-transmural myocardial laser revascularization (N-TMLR) on myocardial ischemic and necrotic areas and angiogenesis. Methods In rabbit models, using Evans′ blue -TTC stain and HE stain technique for measuring ischemic and necrotic areas and observing angiogenesis. Results After T-TMLR and N-TMLR,compared with the control group, the ischemic areas significantly decreased and significant elevation of angiogenesis was observed. But no difference in necrotic areas was observed among the three groups. Conclusion N-TMLR can achieve the same effects with T-TMLR. Inducing angiogenesis via laser channels and decreasing ischemic area may be one of the predominant mechanisms of TMLR whereas laser channels themselves open or not has no relation to the effects of TMLR.

Meanwhile, articles on carcinoma of large intestine published between January 1994 and December 2003 were searched for in CNKI database with the Chinese key words of "carcinoma of large intestine, epidemiology and prevention" and the language restricted to Chinese.STUDY SELECTION: The related literature was selected by the primary tions, hormone level and genetic factors on the morbidity of carcinoma of excluding blind method was not required. Exclusion criteria: review articles and papers of meta-analysis and replicated studies.DATA EXTRACTION: Totally 84 related articles were collected, including 17 retrieved with retrospective approach. Fifty-eight articles met the inclusion criteria, and 26 papers were excluded. Among the excluded papers, 6 papers were about the basic biological and chemical research on carcinoma of large intestine, 12 were about different pathological types of carcinoma of large intestine and distribution of hospitalized cases, 4 were meta-analysis, and 4 were of popular science and delayed diagnosis due to physicians or patients themselves. The collected data showed that the morbidity and distribution of large intestine carcinoma were related to region,age, dietary factor, verminosis, heredity, hormone and chronic intestinal diseases and long-term stress.characteristics, trace element intake and living habits on the morbidity of responding preventive measures for reducing the incidence of large intestine carcinoma.CONCLUSION: With the improvement of living standard, the occurrence .and distribution of carcinoma of large intestine increase, presenting a tendency to occur in young people. Developing good life style and dietary habit and doing moderate exercise can prevent the occurrence of carcinoma of large intestine.

BACKGROUND:Self-assembling short-peptide has been shown to be a kind of hovel nanometer biomaterial.Following culture combined with chondrocytes,self-assembling short-peptide can promote eell marex secretion,cell division and proliferation.and eell phenotype maintenance.For this reason,it has become a candidate for all ideal cell scaffold used for cartilage tissue engineering.OBJECTIVE:To observe the biological characteristics of rabbit articular chondrocytes cultured in three-dimensional nanoscale self-assembling short.peptide KLD-12 hydrogel seaffold.DESIGN.TIME AND SETTING:An observational experiment was performed at the laboratory of Institute for Nanobiomedical Technology and Membrane Biology,Sichuan University between November 2007 and April 2008.MATERIALS:Nanoscale short-peptide KLD-12 with a sequence of Ac-KLDLKLDLKLDL-CONH2 was synthesized by Shanghai Biotech Company,China.METHODS:Chondrocytes were harvested from New Zealand rabbit articular cartilage by enzyme digestion.Following in vitro culture.chondrocytes of passage 3 were inoculated into 4 g/L self-assembling short-peptide KLD-12 solution at a density of 5x 109/L.Peptide gel formation was induced by phosphate buffered saline for three-dimensional culture.MAIN OUTCOME MEASURES:①Observation of chondrocyte morphology in the short-peptide hydrogel with inverted phase contrast microscope.②Detection of intracellular matrix secretion by toluidine blue staining and immunohistochemistry.③Measurement of mRNA expression levels of aggrccan,type Ⅱ collagen and type Ⅰ collagen in chondrocyte-seeded hydrogels by reverse transcription-polymerase chain reaction.RESULTS:①The viability of chondrocytes digested and isolated from rabbit articular cartilage was over 95%.④Chondrocytes cultured in three-dimensional short-peptide hydrogel maintained their round shape,proliferated actively,and aggregated in clusters.In addition.cartilage lacuna could be seen surrounding the clusters.③Both toluidine blue staining and type Ⅱ collagen immunohistochemistry results were positive.The mRNA expression levels of aggrecan and type Ⅱ collagen were increased with time.④Reverse transcription-polymerase chain reaction results revealed that after 3 weeks of in vitro culture in the short-peptide hydrogel,chondrocytes maintained the capability to secrete aggrecan and to express type Ⅱ collagen.CONCLUSION:Self-assembling short-peptide KLD-12 three-dimensional hydrogel Call well inainrain the normal cellular morphology,function and proliferative capability of chondrocytes

Total 11 008 subjects underwent routine health check-up at Tianjin General Hospital in 2008. The results showed that the rate of hyperuricemia was 11.56% ( 1272/11 008 ) in this population, 17. 17% ( 1216/7082 ) for male, and 1.43% (56/3926) for female (P ＜0. 05). The serum uric acid levels were positively correlates with body mass index ( r = 0. 346), waist circumference ( r = 0. 449), systolic blood pressure ( r = 0. 193 ), diastolic blood pressure ( r = 0. 240), total cholesterol levels ( r = 0. 240) and triglyceride ester levels ( r = 0. 284 ). The factors including overweight, hypertension, hyperlipidemia and hyperglycosemia were clustered in subjects with hyperuricemia.

Hybrid procedure is an method that combines surgery and intervenfional catheterization. As collaboration between surgeon and interventionalist has improved, the procedures for complex congenital heart disease is progressing and developing remarkably. Combining echocardiography monitoring in hybrid surgical procedure of complex congenital heart disease not only reduces side effect of extracorporeal circulation and operation time, but also retrieves blind spot of interventional catheterization for infant and low weight baby. Currently it is applied in the field of atrial septal defect, muscular ventricular septal defect, pulmonary stenosis and post-operation residual shunts or stenosis.

Objective To investigate arterial blood gas(ABG)changes induced by different intra- abdominal pressures during CO_2 pneumoperitoneum in rabbits with lung and liver impact injury under controlled hemorrhage.Methods In this study 75 rabbits were randomized into nine groups(6 rabbits in each group)according to the amount of blood loss(6 ml/kg、12 ml/kg、22 ml/kg)and intra-abdominal pressures(5 mm Hg,10 mm Hg,15 mm Hg).After model was established successsfully,respiratory rates (RR),ABG and death rates were observed at pre-pneumoperitoneum,after 0.5 hour and 2 hours under pneumoperitoneum and 0.5 hour after desufflation.Results Without pneumoperitoneum,different blood loss exerted different effect on arterial blood gas:RR,PaCO_2 increased(P

Objective To explore the perioperative nursing method and effect of doing minimal invasive occlusion to children with congenital heart disease via subaxillary incision.Methods The data of 86 children patients with congenital heart disease underwent minimally invasive occlusion via right subaxillary incision were retrospectively analyzed and summarized nursing points including preoperative and postoperative mental nursing,postoperative postural care and sedative care,observing whether the occluder moved or detached and mechanical hemolysis,monitoring ECG and blood pressure,and preventing hemorrhage and thrombogenesis.Results One case of infracristal ventricular septal defect with frequent premature ventricular beat after occlusion was converted to thoracotomy surgery;one case of mixed atrial septal defect with heart rate increasing and dyspnea after 12 hours of occlusion was found occluder detached and immediately converted to remove the occluder and fix the atrial septal defect;The other children were successfully recovered and been discharged.Conclusions Full understanding and strengthened perioperative nursing care of complications of children with congenital heart disease after surgical minimally-invasive surgical closure is the key point to avoid the occurrence of fatal complications and ensure the children recover safely and smoothly.
