Objective To explore the ways of repairing the large long-bone and skin defects as single stage procedures. Methods Five clinic cases were studied, firstly, the arteriae fibularis were restructuered into one or two vaso-nasa which nourished the related fibula segments and the overlying skin, then, binding all of the fibula segments and turn it into a bulky bone with a periosteal vaso-nasa wraparound. The graft was rich in blood supply so osteogenesis activity was vigorous under the periostum, the interspace in the graft soon disappear and the graft increased in diameter gradually. Results All of the harvested skin flaps survived and the wound healed on schedule, besides, the involved fractures were union 1 year later and the grafts were strong enough for weight-bearing and walking 2 year later, Neither fracture occur nor morbidity was created at the donor site, No problem was caused at the ankle. Conclusions It's appropriate way to repair large long-bone and skin defects with a vascularized fibula segments complex transfer incorporationg the overlying skin that was supplied via the same peroneal vessel pedicle.

Objective: To explore the mechanism of congestive heart failure (CHF) by observing the effects of Tingli Shengmai Decoction on myocardial fibrosis and expression of TGF-?1 of rats with CHF. Methods: The CHF animal models were duplicated by the abdomen arteriarctia method, and 60 male wistar rats were randomly divided into the sham-operation group, the model group, the high-dose of Tingli Shengmai Decoction group, the low-dose of Tingli Shengmai Decoction group and the positive medicine (Xinbaowan) control group. After 4 weeks common fed, every group rats were given a certain dose of distilled water or medicine. After 8 weeks, hemodynamic parameters were detected, MASSON staining was used in the study of collagen type in left ventricular interstitial tissue, collagen volume fraction (CVF) were measured by image analysis, and expression of TGF-?1 in myocardium were evaluated by immunohistochemical staining. Results: Compared with the sham-operated group, CVF of model control group increased significantly (P

Objective To investigate the effects of on-pump and off-pump coronary artery bypass grafting on plasma adrenomedullin (ADM) and endothelin-1 (ET-1) levels before and after operation in elderly patients. Methods Elderly patients aged 60 years and over with coronary artery bypass grafting were enrolled in the study and divided into off-pump group and on-pump group, each group had 20 cases. Blood samples were collected before surgery, immediately after operation and 6,24 hours, 3 days after operation. The plasma levels of ADM and ET-1 were dectecded by radio immunoassay. Results The levels of ADM and ET-1 were significantly increased immediately after operation in 2 groups of on-and off-pump. The levels of ET-1 in on-pump group and off-pump group were (67.59±10.18) ng/L and (58.73±9.64) ng/L respectively. The levels of ADM in on-and off-groups were (284.90±36.24) ng/L and (243.25±25.70) ng/L. This showed that in on-pump group, the plasma levels of ADM and ET-1 increased more significantly(P＜0.05). The plasma levels of ADM and ET-1 began to decline at 6 hours after operation, and continued to 24 hours after operation. On 3 days after operation, the plasma levels of ADM and ET-1 in off-pump group returned to the preoperative level, but they were still maintained at a high level in on-pump group.Conclusions For elderly patients, both on-pump and off-pump coronary artery bypass grafting can cause endothelial dysfunction, increasing plasma levels of ET-1 and ADM. But compared with the on-pump coronary artery bypass grafting, the off-pump coronary artery bypass grafting has less influence.

Objective To investigate serological blood typing of the ABO locus which contradict to general law of inheritance in parentage,and the underlying reasons for severe hemolytic disease of newborn(HDN).Methods To research the family whose newborn is AB phenotypes,mother is O phenotypes and father is AB phenotypes.The familiy were genotyped by parentage tests, serological tests,PCR-SSP and direct DNA sequencing at exons 6 and 7 of ABO gene.At the salne time,HDN was detected by micro column gel Coombs (MGCT), and the primary fingerposts of the routine blood tests. Biochemical tests were dynamically observed.Results The results of parentage tests showed that three-generation pedigree have parent-child relationship. The red blood cell(RBC)of this AB phenotypes of this family members strongly agglutinated(4+)with diverse monoelonal anti-A and anti-B antibodies,and their serum did not contain anti-A and anti-B antibodies in blood anti-typing.PCR-SSP can not detect their A and B gene,but DNA sequencing at exons6 and 7 of ABO gene revealed that it had the B(A)803C→G mutation.Conclusions The genetm basis of this parentage are B(A)803G blood gene which harbored both A and B difunctionality of glyeosyhransferases.This was the first report that severe HDN resulting from a large number of A and B antigens in RBC of B(A)phenotype of a newborn,which has clinical significance on ABO locus.
