Relationship between hemorheology and blood gas analysis was studied in 37aged patients with chronic cor pulmonale, including 17 instable and 20 stable. Apparentviscosity (?a) of shear rate of 230.4 (?a(H)) and 5.76/s (?a(L)), TK values, redcell aggregation index(RAI) and PaCO_2 in instable chronic cor pulmonale (AG) were muchhigher than that of stable. patients (BG). Oxygen delivery index (OD) and PaO_2 in AGwere lower than in BG. ?a (H) was negatively correlated with OD and pH (r=-0.58,-0.40, P

External fixators have been widely u sed in treatment of war trauma due to t heir small size,light weight,easy application,and convenience in transport.There are several types of military external fixato r,such as FESSA(Fixateur Externe du Service de Sant?des Arm?es),CMC(Croatian Medical Corps),Synthes and Hoffman-Ⅱ.All of these have been used on the battlefields of Rwandese War,Croatia Wa r and the first Persian Gulf War.Most of military external fixators are unilateral connectable-joint.For temp orary fixation,one bar is enough;by adding another parallel bar,the fixation can be use d for long-time fixing.Facing with a great demand of war trauma treatment ,we should develop new types of military external fixator with more simplicity and less size or weight.

Using Low Shear-30 rheometer, we studied apparent viscosities at high (51.2-128.5s~(-1)), moderate (11.02-37.6s~(-1)), and Low (0.376-8.11s~(-1)) shear rate, viscoelastic properties of whole blood and hemodynamic parameters in 10 patients with acute myocardiac infarction(AMI), comparing with 10 patients with angina pectoris (AP) and 11 normal subjects(NS). It was demostrated that the apparent viscosities of whole blood at different shear rates mentionned above and viscoelastic properties of whole blood (the dynamic modulus G′, the loss modulus G″, "the viscous ?′ and the elastic component ?″ of complex viscosity) increased distinctly and parameters of cardiac function (EF, CO, LVET, PEP/LVET, HI, SV and CI) were abnormal obviously in AMI, in comparing with AP and NS (P

BACKGROUND:The existing bone grafting apparatus are al long tubular-shape, antegrade bone grafting; however, the bone grains within the tube were difficult to put through, along with large bone loss. OBJECTIVE:To design a new concept of minimaly invasive bone grafting apparatus, so as to achieve the minimaly invasive bone grafting in vertebral body and intervertebral space. METHODS: On Solidworks 2012 software platform, the 3D three-dimensional solid modeling technology was employed to design a new concept of gun-shape bone grafting device with the characteristics of headend reversely placing at the grafting position and antegrade pushout, against the problems such as antegrade bone grafting, long bone grafting path and difficulty in bone grafting existing in precious percutaneous or/and transpedicular bone graft apparatus. The virtual assembly and simulative bone grafting surgery were performed with the bone grafting apparatus for observation of the instrument matching degree and grafting surgical procedures. RESULTS AND CONCLUSION: A set of minimaly invasive gun-shape bone grafting apparatus was successfuly designed; its length was 20 cm in total; the length of the front semi-closed bone tube was 2.5 cm. There are two kinds of diameter specifications: inner diameter of 3.5 mm/outer diameter of 4 mm, and inner diameter of 5 mm/outer diameter of 6 mm. Virtual assembly revealed that the grafting apparatus were wel matched. Stimulative surgery displayed that the bone grain loading and launch were simple. The gun-shape bone grafting device is reasonable in design, avoiding pushing too long distance, bone pushing difficulties, bone loss and other problems in previous tubular bone grafting apparatus. Percutaneous, endoscopic vertebrae or intervertebral space minimaly invasive bone grafting can be performed with this apparatus.

Objective To explore the methods and significance of section of multiple fibroadeno mas of breast with better incision.Methods From may 2005 to December 2014,21 cases were per formed by removing multiple fibroadenomas of breast with a new incision.Preoperatively,the diag nostic work-up included clinical examination,breast ultrasonography and/or mammography.A new approach,for removing of multiple fibroadenomas of the breast with the incision in periareolar site,was used in our hospital.All palpable breast lumps were excised with this approach through which the fibroadenomas were removed as a whole unit.Then,the breast cavity were irrigated with normal saline solution,and strict haemostasis of the bed was done by electrocautery.If the resulted cavity was larger,interrupted sutures should be performed with the absorbable stitches;otherwise,it was unnecessary.The skin wound was sutured to the deepithelialized area with Vicryl 5-0 (Ethicon).Results There were 21 cases,who underwent surgery using the described technique through which 95 lumps (0.5 cm× 0.5 cm-6.0 cm× 5.0 cm) were removed and included in the study.All patients' resected tumor specimens were pathologically confirmed as fibroadenoma.No major complications were encountered in any of the patients.The incision was well concealed by the dome of the nipple and the areolar pigmented and corrugated skin.Both doctors and patients were satisfied with postoperative aesthetic effect of the incision scar.Conclusions The incision in periareolar site for excision of multiple fibroadenomatas results in minimal scarring and a better appearance than that can be achieved with traditional methods.This technique,which can improve the aesthetic outcome of breast surgery,should be performed when feasible.
