ObjectiveTo probe into the clinical efficiency of reconstruction to person who had composite tissue defect of the floor of mouth and the lower part of face with the free forearm flap and free iliac bone in the same term.MethodsBefore the surgery, the surgeon should carefully evaluate the scope and shape of defects in 11 cases who had the composite tissue defects of the floor of mouth and the lower part of face, to design the individual forearm flap, so that it matches with the defect region. During surgery, the first resumption of defects using titanium plates forming the basic shape of mandible and the occlusal relationship,then used to re-sawing to take modeling of the iliac bone,transplanted free iliac bone and fixed after the inside of the titanium plate, thereby restoring the continuity of mandible missing.ResultsFree forearm flap and free iliac bone all survived in 11 cases, the success rate of 100％. The patients were followed up for 6 to 12 months, although the shape of restoration areas were different levels of fat, but eating, swallowing and other oral function had been well improved, 7/11 could enter normal diet, 4/11 to enter liquid diet, At the same time, the patients in social activities can communicate in a language daily, sensory function of skin flap and facial appearance has been satisfactory recovery.ConclusionConformal free forearm flap and free iliac bone is an ideal way to reconstruct the composite tissue defects of the floor of mouth and the lower part of face in the same period, not only safe, practical prognostic effect, and also can significantly improve the patients quality of life, which is worthy of reference and use.

Objective To discuss the technique and value of preoperative reformatting with three-dimensional computed tomography technique for C_2 pedicle screw track.Methods GE Light Speed 16 Pro spinal CT scans of 15 adult dry vertebrae were loaded into an imaging station (software ADW4.2).Two methods of C_2 pedicle screw techniques were analyzed through virtual screw trajectory by VR (volume rendering) and MPR (multiple planar reformatting) techniques,in method A,screw entry point was the intersection between the media-vertical and the cranial line of C_2 inferior facet joint,in method B,the screw track was from the cranial and medial quadrant of the dorsal part of C_2 inferior facet joint.Results The screw track could be observed dynamically from any plane.Two vertebrae were ob- served with smaller height in isthmus and the medial edge of the transverse foramen since no space was a- vailable for the screw.The screw trajectories data were compared between method A and method B,which showed that the angles towards the cephalad (in sagittal plane) and midline (in transverse plane) were bigger in method A than in method B (P＜0.05,0.01),but the safe screw diameter was smaller in method A than in method B (P＜0.05),and there was no difference of the screw length between the two methods(P＜0.05 ).Conclusion In this research,the individual C_2 pedicle screw entry points, screw diameter and security screw angle can be simulated,and the screw track can be observed dynami- cally to make sure if it transits the bone structure completely.Preoperative three-dimensional computed tomography reformatting for pedicle screw track is of great value in clinical and basic researches.

Objective The aim of this study was to describe the FICE application on gastric mucosa characteristics including normal and pathological changes, with or without H.pylori infection, and its corre-lation with histopathoingical evidence. Methods A total of 32 patients with dyspepsia symptoms and 5 healthy controls were enrolled into study. Each one underwent esophngogastreduedenoscopy (EGD) examina-tion with FICE and magnified observation. The whole stomach was examined by 3 steps: including conven-tional endoscopy followed by magnifying and FICE observation of the gastric antrum and body as well as biop-sies. All the patients were asked to take the rapid urease test (RUT) 、13C -urea breath test (13C-UBT) . Gastric antrum and body were both sub-classified into following 3 patterns by FICE observation and high reso-lution magnifying endoscopy. The sensitivity, specificity of each FICE pattern of both gastric antrum and body were analysed for the assessment of H. pylori infection, and the consistency with the results of RUT and 13C-UBT. Furthermore, the histopathologic parameters including inflammation、activity、atrophy and intestinal metaplasia were also assessed, Results FICE patterns of gastric antrum and body of all 5 control subjects were type Ⅰ, corresponded to an H. pylori negative and non-atrephy gastric mueosa. In study group on gastric antrum, 14 cases of FICE type Ⅰ pattern were noted and only 1/14(7. 1%) corresponded to an H. pylori positive gastric mucosa. 13 cases of FICE type Ⅱ pattern were noted and 10/13 (76. 9%) corresponded to an H.pylori positive mucosa and 9/13(69. 2%) were positive for both gastric atrophy. 5 cases of FICE type Ⅲ pattern were noted and 5/5 (100%) corresponded to an H. pylori positive mucosa and 3/5 (60%) were positive for both gastric atrophy and intestinal metaplasia. There was statistical difference in prediction of H. pylori infection between type Ⅰ FICE pattern and type Ⅱ or type Ⅲ pattern on gastric antrum (P <0. 01). In study group on gastric body, 15 cases of FICE type Ⅰ pattern were noted and only 1/14(7. 1%) corre-sponded to an H. pylori positive gastric mucosa. 13 cases of FICE type Ⅱ pattern were noted and 11/13 (84. 6%) corresponded to an H. pylori positive mucosa. 4 cases of FICE type Ⅲ pattern were noted and 4/4 (100%) corresponded to an H.pylori positive mucosa. There was statistical difference in prediction of H. pylori infection between type Ⅰ FICE pattern and type Ⅱ or type Ⅲ pattern on gastric body (P < 0. 01). Conclusion FICE in combination with high resolution magnifying endoscopy is valuable for identifying the normal gastric mucosa, H.pylori infection and its associated gastritis, gastric atrophy as well as intestinal metaplasia.

Objective To determine attention networks impairmnet in patients with localized brain injury and to examine the characteristics of the impairment.Methods The attention network test was used to compare patients(n=59)with controls(n=53)on the efficiency of 3 anatomically defined attention networks:alerting,orienting,and executive control.Results Firstly,patients with frontal lobe injury showed a significant deficit in the executive network(frontal lobe injury,controls:(143.7±46.6),(91.6±46.4)ms,Z=-4.714,P＜0.01)and also a significant deficit in the orienting network(frontal lobe injury,controls:(71.2±35.2),(55.1±21.8)ms,Z=-2.125,P＜0.05).There was no deficit in the alerting network(Z=-0.901,P＞0.05).Secondly,the orienting network effect was significantly lower in patients with parietal lobe injury((34.9±25.2)ms)than in normal controls((55.1±21.8)ms.Z=-2.418.P＜0.05).However,there were no significant difierences between the other two networks and between the patients and the controls(Z=-1.873,-0.186.P＞0.05).Thirdly,patients with temporal lobe injury showed no deficit in the three networks(Z=-0.037,-1.224,-0.718,all P＞0.05)as well as in overall RT and accuracy(Z=-1.385,-0.699,all P＞0.05).Conclusions These results suggest that there are selective impairments of the orienting and executive networks in patients with the frontal lobe and the parietal lobe injury,while the alerting network is spared.Furthermore,the frontallobe plays a key role in the executive control.meanwhile,the orienting network is closely related with the parietal lobe.

Objective To study the changes and significance of serum beta 2-microglobulin(?2-MG),cytocine interleukin-2(IL-2) in the clinical progress of childhood idiopathic thrombocytopenic purpura(ITP).Methods One hundred and ten patients of childhood ITP were chosen for the test group(70 cases of primary ITP and 40 cases of recurrent ITP),and 110 normal children for the control group.Levels of serum ?2-MG and IL-2 were determined by radioimmunoassay kit and analysed with two sample t-test.Results Among the patients,the serum IL-2 levels were significantly lower and serum ?2-MG levels were significantly higher than those in control group(P0.05).Conclusion Determining serum IL-2 and ?2-MG levels has important significance to reflect the progress of disease and direct treatment.

BACKGROUND:Xenogeneic ligament is readily available, which has ligament scaffold structure and is conducive to tissue ingrowth and creeping substitution. After processing, the xenogeneic ligament, with the presence of good growth scaffold function, can be completely eliminated antigenicity that can cause immune rejection. OBJECTIVE:To study the feasibility of biological xenogeneic ligament graft instead of alogeneic ligament graft for reconstruction of goat anterior cruciate ligament. METHODS: Twenty-four healthy adult goats were randomly divided into A, B, C groups, and then, the left knee joints of goats were removed to establish animal models of anterior cruciate ligament injury in the three groups. After the establishment of the tibia and femoral bone tunnel, groups A, B, C were respectively transplanted with biological xenogeneic ligament graft combined with bone marrow mesenchymal stem cels, biological xenogeneic ligament graft alone, and alogenic ligament. RESULTS AND CONCLUSION: After implantation, no rejection but good biocompatibility was found in the group A, in which, the transplanted ligament as a functional scaffold for anterior cruciate ligament reconstruction, and new tissues in-grew and replaced the scaffold under intraarticular environment to form the new ligament with good bone tendon healing. However, there were no differences in histology, immune response, biomechanical findings between groups A and C. Additionaly, in the group A, the host tissues were found to grow into the scaffold and establish a micro-circulation. These findings indicate that xenogeneic ligament combined with bone marrow mesenchymal stem cels can accelerate the establishment of micro-circulation and promote the growth of ligaments, especialy improve the ligament revascularization significantly, but has no influence on the biological characteristics of the ligament.
