Objective To investigate the effect of aprotinin on the inflammation response to reinfusion of shed blood during operation after being aspirated, filtered and washed using cell saver.Methods Twenty-four ASA I - II patients undergoing elective spinal surgery under general anesthesia were randomly divided into 2 groups: aprotinin group ( n = 12) and control group ( n = 12) .The patients were premedicated with intramuscular pentobarbital 0.1 g and atropine 0.5 mg. Anesthesia was induced with propofol 2 mg ? kg -1 , fentanyl 2-4 ?g ? kg-1 and vecuronium 0.1-0.3 mg ? kg-1 and maintained with isoflurane, propofol infusion and intermittent i. v. boluses of fentanyl and vecuronium. The patients were mechanically ventilated after tracheal intubation. In aprotinin group aprotinin 10 ? 105 IU was given before skin incision and another dose of aprotinin 10 ? 105 IU was continuously infused during operation. The blood shed during operation was collected, anticoagulated with heparin, filtered, washed and reinfused using AutoLog cell saver. Blood samples were taken from CVP line before skin incision (T1 , baseline), 30 min after reinfusion of salvaged bloods (T2) and at the end of operation (T3 ) for WBC and neutrophil granulocyte counts and determination of expression of CD11b and CD18 on the surface of neutrophil granulocytes using flow cytometry. Results The two groups were similar with respect to the general condition of the patients, duration of operation and account of shed blood reinfused. (676? 353) ml was reinfused in control group. The expression of CD11b and CD18 on the surface of neutrophil granulocytes increased significantly at T2 and T3 as compared to the baseline at T1 in control group ( P

Objective To observe the effects and its efficacy of Ozagrel on CD62p and CD63 expressions in platelets of patients with acute cerebral infarction(ACI).Methods 64 patients with ACI were devided into two groups:Ozagrel group and Xuesaitong group(control group).The expression levels of CD62p and CD63 in 64 patients with ACI(before and after treating)and that in normal people(normal group)were measured with whole blood flow cytometry.The clinical effect of treatment in the Ozagrel group and the control group were observed and compared.Results The expression levels of CD62p and CD63 in patients with ACI were higher than those in the normal group(all P

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 investigate the projects funded by ministry of national science and technology (NSTP) in China allocated to oral medicine from 2003 to 2013.Methods The data regarding the NSTP allocated to oral medicine research from 2003 to 2013 were collected,including funding years,the expenses and numbers of programs,the secondary discipline of oral medicine and the program units,etc.Multidimensional analyses were provided subsequently.Results From 2003 to 2013,a total number of 59 projects and 210 million CNY supported by NSTP were allocated to oral medicineresearch.The development trend showed increased year by year.The oral medicine researches were allocated by almost all major types of NSTP and the funding directions were tending to diversified development.But,the projects units were relatively concentrated in clinical,teaching and research institutions,only few enterprises.Conclusions Over the past 10 years,the sustainable improvement of NSTP in oral medicine research has led to the development of oral medicine discipline.NSTP has becoming an important way for oral medicine research to obtain State-level funding.

The study assessed the early functional outcomes with cemented titanium implants of radius in the treatment of comminuted fractures of radial heads. The functional outcomes of arthroplasty with cemented titanium implants of radius in the treatment of radial head fractures (Mason Type III: 6; Mason Type IV: 4) in 10 consecutive patients (mean age, 38 years) were evaluated over a mean time of 23.7 months (18-31 months). The patients were assessed on the basis of physical examination, functional rating (Mayo) and radiographic findings. The parameters evaluated included motion, stability, pain, and grip strength. Five patients were considered to have excellent results, 4 patients had good results and 1 patient had fairly good results. There were no cases of infection, prosthetic failure, heterotopic ossification or dislocation. When medial collateral ligament was injured, radial head became the main stabilizing structure of the elbow. Titanium radial head implant may provide the stability similar to that of native radial head. We believe that titanium radial head implants may be indicated for the Mason Type III and Mason Type IV radial head fractures.

Objective:To compare two digital methods of quantitatively accessing the degree of facial asymmetry by three-dimensional data.Methods: The three-dimensional data of 20 subjects were got by the FaceScan, and then were input to the reverse engineering software Imageware 13.0 and Geomagic 12 .Their mirror data were acquired and superimposed with the original data by the methods of interactive closest points ( ICP) and Procrustes analysis ( PA) .The mid-sagittal planes of the two methods were ex-tracted respectively, the degree of facial asymmetry and the distance of 21 automatic landmarks to mid-sagittal plane were calculated and compared.Results:The paired t test was taken and t=1.346, P=0.193.Conclusion:We can safely come to the conclusions that for the subjects with no evident facial asymmetry, there are no significant difference between the PA and the ICP methods for extracting the mid-sagittal plane from three-dimensional data.

Objective To summarize the experience of double layered anastomosis in thoracoscopic and laparoscopic esophagectomy,and to explore its impact on the postoperative anastomotic complications.Methods Patients with thoracoscopic and laparoscopic esophagectomy from September 2014 to Auguest 2015 were retrospectively included.The cervical anastomosis were conducted by hand-sewn double layered anastomosis on the posterior wall of the gastric remnant,with the anastomotic configuration of end-to-side.The patients' general information and postoperative complications were recorded and analyzed.Results 45 patients with esophageal squamous cell carcinoma were included.The major postoperative complications were gastric dilatation(6/45,13.3％),hoarseness(5/45,11.1％),anastomotic leak/gastric necrosis(2/45,4.4％),anastomotic stricture(0/45,0).All patients were discharged from hospital with no perioperative death.Conclusion Hand-sewn double layered anastomotic technique could be safely used in thoracoscopic and laparoscopic esophagectomy,which could assure the security of the anastomosis.The anastomotic complication rates for this technique are rare enough to be recommended,as compared with other anastomotic methods reported in the literatures.

Objective To characterize the CT and MRI features of Osgood-Schlatter disease (OSD),and explore the feasibility of staging OSD by using CT and MRI.Methods The imaging data of the 27 cases with OSD were retrospectively analyzed,and fea-tures of MRI and CT were characterized.Results All 27 cases with OSD were featured with different extent of edema within the pa-tellar tendon.The portion already exhibited edema in the secondary ossification center in 5 cases,which showed high signal intensity on the T2 WI.There were 1 5 cases which exhibited ossified or tears in the secondary ossification center,and 5 of them were featured with opened shell-like separation on sagittal radiograph.Seven cases had isolated solitary ossicles located at the lower part of the pa-tellar ligament,which is also thickening.Among the 7 cases,one showed hypertrophy in the tibial tuberosity.Three cases examined with CT scan,exhibited ossified nodules located at the lower part of the patellar ligament.Conclusion OSD has characteristic CT and MRI features,and MRI scan is an important imaging method to show edema and morphological changes of patellar tendon in OSD,which could help to identify the stage of OSD and predict the prognosis.
