The clamp-on shapping plate implant, composed of a main rod with 3～4 pairs of curved short arms attached on both sides of the rod, possesses multifixing action to the fracture without hindering the movement of the adjacent joints. It is especially useful for the fixation of comminuted fracture of the short tubural bones which are difficult to be fixed by other methods. In the period of 1987.8～1990. 2,64 cases of such fractures had been treated with this device. Followup results in 52 cases showed that all the fractures thus treated healed nicely without any case of malunion. Total duration of external immobilization was relatively shorter and the functional recovery of the joints also much better.

Objective To investigate the effects of two different doses of fentanyl given by target-controlled infusion (TCI) on stress responses during operation under general anesthesia and evaluate the accuracy of TCI of fentanyl.Methods Thirty ASA Ⅰ-Ⅱ patients (14 males, 16 females) aged 24-69 yr, weighing 48-77 kg scheduled for elective abdominal surgery under general anesthesia were randomly divided into three groups with 10 patients in each group : group Ⅰ and Ⅱ received fentanyl by TCI with the target effect-site concentration set at 2 ng Ⅲ ml 1 (Ⅰ) and 4 ng ? ml-1 ( Ⅱ ) during induction and maintenance of anesthesia, while group Ⅲ received a bolus of fentanyl 3 ?g?kg-1 during induction of anesthesia. In addition to fentanyl, anesthesia was induced with propofol 2mg?kg-1 and vecuromum 0.1 mg?kg-1 and maintained with propofol infusion at 6 mg?kg-1?h-1 and intermittent i. v. doses of vecuronium BP (SBP, DBP, MAP ) , HR, SpO2 and PET CO2 were recorded before induction of anesthesia (T0 ,baseline), at the loss of consciousness (T1), immediately after tracheal intubation (T2), 5 and 10 rnin after intubation (T3 , T4), during skin incision (T5) and exploration of abdominal cavity (T6). Blood samples were obtained for determination of plasma norepinephrine (NE) and epinephrine (E) concentrations and blood glucose ( BG) and fentanyl concentrations at T0, T2, T4 and T5 by HPLC. Results There were no significant differences in sex, age and body weight among the three groups. There were no significant changes in plasma NE, E and BG concentrations, which were all within normal range in the three groups. The SBP and MAP in group Ⅲ were significantly lower than those in group Ⅰ and Ⅱ at T1 ( P

Objective To investigate the adjunctive therapeutic effects and safety of intravenous immunoglobin (IVIG) for treating pneumonia following kidney transplantation.Methods Sixteen cases of pulmonary infection after kidney transplantation were divided into two groups.Twenty-eight cases were subjected to IVIG therapy (0.2 g·kg-1 ·day-1) for 7-10 days besides the standard specific anti-bacterial,anti-fungal,and anti-virus treatment and regular immunosuppressive regimen with dose adjustment (IVIG group),and the control group was only treated with standard specific anti-pathogen therapy.The incidence and mortality ofsevere pulmonary infection,levels of serum IgG,T lymphocyte subsets,and creatinine in the two groups were observed.Results The effective power of IVIG group and control group was 100 ％ and 93.75 ％ (P＜0.05).The incidence of severe pneumonia in IVIG and control groups was 0 and 12.5％,respectively (P＜0.05),with the mortality being 0 and 6.25％,respectively (P＜ 0.05).The levels of serum IgG were significantly increased in IVIG group as compared with that before treatment and in control group.There were no significant adverse reactions associated with IVIG infusion.Conclusion As an adjunctive therapy,IVIG treatment for pulmonary infection can reduce the incidence of severe pulmonary infection and mortality after kidney transplantation,further increase the survival rate of patients after kidney transplantation.

Objective To investigate the outcome of free posterolateral leg perforator flap in the reconstruction of soft tissue defects of oral and maxillofacial area.Methods From February,2014 to August,2016,16 patients were performed defect reconstruction following oral cancer ablation with free posterolateral leg perforator flap including 3 cases of sequamous cell carcinoma of the tongue,6 cases of carcinoma of the buccal mucosa,7 cases of sequamouse cell carcinoma of the floor of mouth.The flap ranged from 5.0 cm×3.0 cm to 13.0 cm ×9.0 cm in size,and were adjected to the soft tissue defects of oral and maxillofacial area.The outcome of reconstruction was evaluated by considering the facial appearance,the swallowing and the speach function,the ranges of mouth opening and patient prognosis.Results All 15 transplanted flaps survived well and only 1 survived after disposing in time,because of vascular crisis.The donor sites were closed directly without donor-site morbidity.All patients were satisfactory with their facial appearance,the ranges of mouth opening and swallowing and speech function.Conclusion The free posterolateral leg perforator was an ideal free tissue for repairing functionally oral and maxillofacial defects,sinceit including some beneficial characteristic such as constant blood vessel,flexible and divese design,abundant and position-latent donor site tissues,small operation loss,flexible preparation and loss of major vascular nerves.

Objective:To construct human adipose-derived mesenchymal stem cells (hASCs)-biomate-rial mixture 3D bio-printing body and detect its osteogenesis in vivo,and to establish a guideline of osteogenesis in vivo by use of 3D bio-printing technology preliminarily.Methods:P4 hASCs were used as seed cells,whose osteogenic potential in vitro was tested by alkaline phosphatase (ALP)staining and alizarin red staining after 1 4 d of osteogenic induction.The cells were added into 20 g/L sodium alginate and 80 g/L gelatin mixture (cell density was 1 ×1 06/mL),and the cell-sodium alginate-gelatin mixture was printed by Bioplotter 3D bio-printer (Envision company,Germany),in which the cells’survival rate was detected by live-dead cell double fluorescence staining.Next,the printing body was osteogeni-cally induced for 1 week to gain the experimental group;and the sodium alginate-gelatin mixture without cells was also printed to gain the control group.Both the experimental group and the control group were implanted into the back of the nude mice.After 6 weeks of implantation,the samples were collected,HE staining,Masson staining,immunohistochemical staining and Inveon Micro CT test were preformed to analyze their osteogenic capability.Results:The cells’survival rate was 89%±2% after printing.Six weeks after implantation,the samples of the control group were mostly degraded,whose shape was irregu-lar and gel-like;the samples of the experimental group kept their original size and their texture was tough.HE staining and Masson staining showed that the bone-like tissue and vessel in-growth could be observed in the experimental group 6 weeks after implantation,immunohistochemical staining showed that the result of osteocalcin was positive,and Micro CT results showed that samples of the experimental group had a higher density and the new bone volume was 1 8%±1%.Conclusion:hASCs-biomaterial mixture 3D bio-printing body has capability of ectopic bone formation in nude mice,and it is feasible to apply cells-biomaterial mixture 3D bio-printing technology in the area of bone formation in vivo.
