Objective To study the effects of cooking practice education on their status of nutrient intake and blood glucose control in patients with type 2 diabetes mellitus (T2DM) over 60 years old.Methods Four-hour cooking practice education lecture was offered per month for 57 patients with T2DM over 60-year old based on balance diet and food exchange list,with features including requiring patients joining the lecture with their family members together,demonstration of raw and fresh dietary materials and cooked food,choice of food to eat by the patients themselves according to their own dietary regimen.Sixty patients with T2DM who were only educated by outpatient department of nutrition for 35 minutes were selected as control.After twelve months of education,indices such as scores of awareness of knowledge of food exchange list,status of nutrient intake and blood glucose control,and so on,were compared between the two groups to evaluate the effects of cooking practice education.Results After 12- month education,score of knowledge of food exchange list in the experiment group increased significantly,as compared to that in the control group.Intake of energy [(6304?826) kJ] and fat [(46?6) g] decreased significantly in the experimental group [(6921?860) kJ and (63?9) g,respectively],and fasting blood glucose [(7.1?0.8) mmol/L],postprandial blood glucose [(11.2?1.1) mmol/L] and glycosylated hemoglobin A1c [(6.2?0.5)%] were decreased significantly,as compared to those in the control group [(7.8?0.9) mmol/L,(12.4?1.2) mmol/L,and (6.5?0.7)%)],respectively.Conclusions Cooking practice education is effective to correctly use diet regimen and improve status of nutrient intake and control of blood glucoses for over-60-year patients with T2DM.

OBJECTIVETo analyze the influence of included angle between the anterior aspects of S2 and S vertebral bodies on pelvic inlet imaging in the pelvic midline sagittal plane.

METHODSTotally 58 axial pelvic CT scans were chosen as study objects including 43 males and 15 females,with an average age of 40.7 years old (ranged,18 to 68 years old). The angles between the anterior aspects of S2 and S1, vertebral bodies and the horizontal plane on midline sagittal CT reconstruction were measured to simulate the optimal S2 and S1 inlet angles. The included angle between the anterior aspects of S2 and S1 vertebral bodies was calculated by subtrocting the S1,inlet angle from the S2 inlet angle defined as a base number. Then, the impact of the calculated included angles on the pelvic inlet imaging was analyzed. Results:The S2 inlet angles averaged (30.5±6.5) degrees; the S inlet angles averaged (25.7±5.9) degrees. The difference between them was significant (t=3.35, P=0.001). Ten patients had zero angle between the anterior aspects of S2 and S1 vertebral bodies; 14 patients had negative angle, averaged-(8.9±8.1) degrees; 34 patients had positive angle,averaged (11.8+6.4) degrees.

CONCLUSIONThe difference of included angle between the anterior aspects of S2 and S1 vertebral bodies leads to the difference between S1 inlet view and S2 inlet view in most cases, complicating the pelvic inlet imaging,and affecting the reliability of the application of pelvic inlet view. Utilizing the angles measured on the preoperative midlihe sagittal CT reconstruction to obatin the patient-customized S1 and S2 inlet views could accurately guide the S1 and S2 iliosacral screw insertion.

OBJECTIVESTo research radiographic anatomy of the main structure of the pelvic Teepee view, including its azimuth direction and view anatomy structure.

METHODSFrom June 2013 to June 2014 adult pelvic CT examination results were filtered, excluding skeletal deformities and pelvic osseous destruction caused by tumors, trauma, etc. The data of 2.0 mm contiguous CT scan of 9 adults' intact pelves was,selected and input into Mimics 10.01 involving 7 males and 2 females with an average age of (41.2±10.3) years old. Utilizing the software, the 3D CT reconstructions of the pelves were completed. Setting the transparency being high,the pelvic 3D reconstructions were manipulated from the pelvic anteroposterior view to the combined obturator oblique outlet view and fine-tuned till the regular Teepee-or teardrop-shaped appearance emerges. Cutting tools of the software were at the moment applied to separate the "Teepee" from the main pelvis for each reconstruction. Then the "Teepee" and the rest (main) part of the pelvis were displayed in different color to facilitate the analysis on the Teepee, iliac-oblique, and anteroposterior views.

RESULTSThe "Teepee" started from the posterolateral aspect of the anterior inferior iliac spine and finished at the cortex between the posterior superior iliac spine and the posterior inferior iliac spine in a direction of being from caudal-anterior-lateral to cranial-posterior-medial. The radiographic anatomical composition of the "Teepee" contained one tip, one base,and two aspects. With the inner and outer iliac tables being the inner and outer aspects of the "Teepee", the tip is consequently formed by their intersection. The base is imaged from the cortex of the greater sciatic notch. The medial-inferior-posterior portion of the "Teepee" contains a small part of sacroiliac joint and its corresponding side of bone of the sacrum.

CONCLUSIONSThe "Teepee" is a zone of ample osseous structures of the pelvis, aside from a small medial-inferior-posterior portion, the main zone of which can be accepted as a safe osseous zone for the anchor of implants stabilizing certain pelvic and acetabular fracture patterns. The Teepee view can be utilized as guidance for the safe percutaneous insertion of such implants.

OBJECTIVESTo introduce a classification system of upper sacral segment and its significance based on the continuous pelvic axial computed tomography scan.

METHODSThe whole pelvis 2.0 mm thick axial scan images of 127 cases were observed, the sacroiliac screw channel of S1 were measured, according to the size of the transverse screw channel the upper sacral segment were classified. Such as transverse screw channel existed and in at least 4 layer scan images its width was > 7.3 mm, it was defined as sacral segment of the normal type. Such as transverse screw channel existed and its maximum width was 7.3 mm or less on scanning level, it was defined as a transitional. Such as transverse channel did not exist, or its width on all scanning level was 0 mm or less, it was defined as dysplastic. Various cases,percentage, and the average of the transverse screw channel were calculated.

RESULTSThere were 58 normal (45.7%),42 transitional (33.1%), and 27 dysplastic (21.2%) upper sacral segments with an averaged width of the tansverse screw channel of 13.9 mm, 5.2 mm, and 0.9 mm, respectively. Each specimen could be defined as one of the three types of upper sacral segment without exceptions.

CONCLUSIONIt is possible to insert a transverse iliosacral screw into a normal upper sacral segment when indicated because of the capacious transverse screw channel. The transverse iliosacral screw placement into the transitional and dysplastic upper sacral segments was contraindicated because of the limited or none transverse screw channel. The transitional upper sacral segment was superior to the dysplastic segment due to its starting point location restriction on the true lateral sacral view.

OBJECTIVETo study the surgical reconstruction of secondary fracture deformities of the nasal-orbital ethmoid area.

METHODSTypical bicoronal and subciliary incisions or the adjacent scar incision were employed to expose the fractured area. The flattened nasal bone was narrowed by curved osteotomy along the medial orbital rims and trimed with a bur. 2-3 pieces of cranial outer table were used to reconstruct the nasal framework, which were fixed to the frontal bone with mini-plates. After the medial orbital wall and orbital floor were exposed, the herniated orbital contents were released and reduced to the orbital cavity. The fractured orbital walls were repaired precisely with autogenous cranial outer table or Medpor. The medial canthal tendons were anchored superior-posteriorly to the lacrimal fossa with transnasal wires.

RESULTSFrom December 1996 to December 2001, 34 cases of severe nasal-orbital ethmoid fracture deformities were repaired with this technique. Of them, 12 cases had combined orbital-zygomatic fracture, 4 cases had fontal sinus fracture, 1 case had Le Fort II and 1 case had Le Fort III fracture. All the patients recovered well and their facial appearance improved greatly.

CONCLUSIONSThe key points for surgical reconstruction of the periorbital post-fracture deformities are narrowing the flattened nasal root by curved osteotomy, the nasal framework reconstruction with autogenous bone graft, the orbital wall repair to correct enophthalmos, and most importantly, the medial canthal tendon reduction and canthal plasty.
