Objective To summarize the nursing care experience for right ventricular dysfunction after orthotopic heart transplantation.Methods Clinical data of 67 patients underwent heart transplantation were retrospectively analyzed from January 2007 to December 2010.Results 58 patients were discharged after they were cured,9 patients died.67 patients were affected by different degrees of increasing central venous pressure (CVP)early postoperation and right ventricular dysfunction,28 cases received extracorporeal membrane oxygenation(ECMO) assistant,6 cases received continuous renal replacement therapy(CRRT).Among 58 discharged patients,the heart function level showed class two in 54 cases and class three in 4 cases.Conclusions After heart transplantation,followed with intensive care and close observation of right heart failure symptoms,providing effective care and support,active prevention and treatment for right heart failure,maintaining vital organs function were key to successful heart transplantation.

Vascularization is the basis of tissue regeneration. To get engineered tissue, it is necessary that timely and enough nutrition be available to the seed cells, especially those within the biomaterials. Therefore reconstruction of blood supply is the key step leading from basic research to clinical application. Thee major methods have been used to reconstruct blood supply: promotion of vessel growth by means of VEGF, combined grafting of vascular endothelial cells and osteoblasts and microsurgical techniques. The microsurgical techniques, such as wrapping around with pedicled fascia flap, wrapping around with vascularized muscle flap and blood vessel implanting, can help reconstruct blood supply when engineered tissue is fabricated. When engineered tissue is used in clinic to repair defects in vicinity, vascularization can be done in the defect area. But when no fascia flap, muscle flap or vessel can be used in the defect area, the local defects can be repaired through reconstruction of vascularized engineered tissue in other areas and through second stage transplantation with microsurgical techniques.

Through a comparison of the differences between China and Australia in the models of hospital management and the roles of hospital managers, the paper expounds the specific features of the model of “decentralized powers” and “professional presidents” and the model of “centralized powers” and “expert-turned presidents”. It argues that under the pressures of both internal and external changes, including rapid socioeconomic development, the deepening of the health care reform, the effect of China's accession to the WTO on the medical and health industry, the development of a contingent of professional health care managers in China has become an inevitable trend.

Objective To investigate the clinical efficacy of joint-corresponding point selection plus exercise acupuncture in treating acute ankle sprain.Method Enrolled 70 patients with acute ankle sprain were randomly allocated to two groups.The treatment group received joint-corresponding point selection plus exercise acupuncture and the control group,elastic bandage fixation.Both groups were given ice compress,mobilizationand elevation as auxiliary measures.Treatment was provided seven days as one coursefor a total of two courses.The pain, tenderness, swelling andrange of activitieswere scored in the two groups of patients before and after treatment.Thetherapeutic effects were compared.Result The total efficacy rate was 88.6% in the treatment groupand54.3% in the control group.The therapeutic effect was significantly better in the treatment group than in the control group (P<0.01). Joint pain, tenderness, swelling and activity scores decreased in the two groups after treatment (P<0.01). Joint tenderness and activity scores were lower in the treatment group than in the control group after treatment (P<0.01).Conclusion Joint-corresponding point selection plus exercise acupuncture has clinically a marked therapeutic effect on acute ankle sprain.

Objective To explore the association between the polymorphism in IL-28B gene and the interferon virological response in HBeAg-posi-tive chronic hepatitis B patients. Methods A literature search was performed on PubMed,web of Science,China Bio Medicine(CBM)and wan-Fang database. The references was screened with the inclusion and exclusion criteria,and then data were extracted and methodological quality of the studies was judged. Statistical analysis was carried out with RevMan 5.3 and STATA 11.0. Results Totally 7 publications were recruited for the study,including 1 345 patients. The meta-analysis showed that there was no significant difference of interferon response between HBeAg-positive chronic hepatitis B patients with rs8099917TG/GG alleles and rs8099917TT alleles (P= 0.20). There was no statistical difference between Rs12979860CC and CT/TT allele for the sustained virological response(P=0.75). Conclusion Our current meta-analysis suggests that there was no correlation of rs8099917,rs12979860 polymorphism in IL-28B with the sustained virological response to interferon in HBeAg-positive chronic hepatitis b.

Objective To detect 5′ NT, ALP and some guide lines associated to hepatic diseases and to discuss the application of 5′ NT to diagnose and distinguish disease between hepatic and osteal. Methods 30 cases in control team, total disease 63 cases, to measure their values of 5′ NT and ALT. Results The average values of control, infracted jaundice, hepatocirrhosis, gall stone, hepatitis, liver cancer, osteal disease are respectively 3.27 IU/L, 17.84 IU/L, 9.6 IU/L, 14.1 IU/L, 10.45 IU/L, 21.45 IU/L, 4.47 IU/L, the values in hepatics and gall disease are prominently higher than those in others teams ( P

Objective To discuss digital subtraction angiography(DSA)findings and interventional treatment of broncho-costoarterial pulmonary circulation fistula(BPF).Methods Fifty one patients with massive hemoptysis were undergone DSA showing 19 cases with BPF.All BPF were cmbolized with 500～700?PVA, silk particles and segments,and steel coil;separately or in combination according to shunt orifice size and blood flow velocity.Results There were 4 types of BPF demonstrated by DSA according to feeding and drainage vessels,including 13 cases of bronchial artery-pulmonary artery shunt(AAS),2 cases of bronchial artery-pulmonary venous shunt(AVS),3 cases of intercostal artery-pulmonary artery shunt(IAPS)and 1 case of bronchial arteriovenous malformatoin(B-AVM).All patients were followed up for 1～4 years,with 18 cases of complete symptomless during 7 days postoperatively obtaining,the effective rate of 94.7%.There were 3 recurrent cases within 1 year with the recurrent rate of 15.79%.Conlusions BPF is the main factor for inducing and aggrevating pulmonary hemoptysis and interventional embolization serves as a safe and effective treatment.The method could be used repeatedly for recurrent cases and furthermore emphasis should be put on treating the primary pulmonary diseases simultaneously.(J Intervent Radiol,2007,16:84-87)

Objective To explore the effects of hypoxia on the growth,mitochondria distribution and function of mouse embryonic fibroblasts(MEFs).Methods MEFs were sub-cultured in the hypoxia group containing 5％ oxygen and normal oxygen group containing 20％ oxygen,every 24 hours,living MEFs were counted by using trypan blue staining.Mito-Tracker Green was used to stain mitochondria,then cells were observed by using laser confocal microscope.The ATP kit was used to detect ATP synthesis.Results During the logarithmic phase,the numbers of living cells in the hypoxia group were higher than those in the normal oxygen group,the differences were statistically significant (P＜0.05).The percentages of perinuclear mitochondrial in the hypoxia group were higher than those in the normal oxygen group,the differences were statistically significant (P＜0.05).Meanwhile,the significant difference was found in the ATP level between the two groups (P＜0.05).Conclusion The distribution of mitochondria in MEFs and energy synthesis are influenced by the hypoxic culture condition,which could be better for promoting cell growth compared with normal oxygen culture condition.

Lung adenocarcinoma accounted for about 70％ of non-small cell lung cancer,and now a higher risk of detected.Early diagnosis and early treatment can significantly improve lung adenocarcinoma patients after operation and improve the survival rate of patients.Bronchoscope clinical diagnosis of lung cancer and chest wall puncture in pathology has problem in that it is an operation and specimen is not easy to get,compared to tumor markers that are easy to obtain.A series of studies in recent years have shown that the joint detection of tumor markers has important value in early detection and diagnosis,prognosis assessment,and tumor recurrence of lung adenocarcinoma.
