Objective To explore the effects of single rectangle cage interbody fusion combined with pedicle screw fixa?tion for isthmic spondylolisthesis. Methods Data of the 34 cases with isthmic spondylolisthesis hospitalized at our department from March 2012 to February 2015 were retrospectively analyzed. All cases were operated by posterior pedicle screw fixation com?bined with single rectangle cage interbody fusion. There were 21 males and 13 females, aging from 18 to 63 years old (with an aver?age age of 41.6±8.2 years). Lesion segments were L4 in 15 cases and L5 in 19 cases;there were 12 cases in Meyerding I degree, 16 in II degree and 6 in III degree;28 patients had lower back pain associated with lower limb pain;19 patients had lower back pain associated with numbness of lower limb;18 patients had lower back pain associated with lower limb muscle weakness and 2 pa?tients had urination and defecation function disturbance. The surgical operation time, bleeding, postoperative drainage flow, graft fusion rate, complications were measured, and the intervertebral disc height, Japanese Orthopaedic Association (JOA), Oswestry disability indes (ODI), visual analogue scale (VAS) score were compared before and after treatment. Results The operation of 34 patients was successfully completed with the average operation time of 1.8 ± 0.8 h, and the bleeding in operation was 362.4 ± 93.7 ml, while postoperative drainage flow was 116.3±54.2 ml. All patients were effectively followed up for 12 months to 46 months (av?erage, one year and 10 months). Two weeks after operation, the intervertebral disc height were obviously increased (9.85±1.11 mm, 9.63 ± 1.04 mm), and there were significant difference compared with preoperative results (6.53 ± 0.98 mm, 6.24 ± 1.07 mm), but there were no significant difference compared with the latest follow?up results (9.23±1.33 mm, 9.30±1.16 mm). At the latest follow?up, JOA score was 13.19±1.08, ODI score 12.34±7.52, VAS score 2.23±1.51, and there were significantly different in each score compared with preoperative results. The symptoms of low back pain, lower limb nerve dysfunction and quality of life were signifi?cantly improved compared with preoperative situation. At the 16 month follow?up, all postoperative patients with vertebral body bone graft were judged to be fused. There was no pedicle screw loosening, fracture and so on. Conclusion Single rectangle cage interbody fusion combined with pedicle screw fixation for the treatment of isthmic spondylolisthesis is a kind of mini?invasive, less bleeding, safe and effective surgical method.

Objective To evaluate the value of low-density lipoprotein-cholesterol (LDL-C) and non-high-density lipoprotein-cholesterol (non-HDL-C) in differential diagnosis of familial hypertriglyceridemia (FHTG) and familial combined hyperlipidemia (FCHL).Methods We recruited 9 FHTG pedigrees (94 subjects) and 24 FCHL pedigrees (94 subjects) and then divided them into affected groups and non-affected groups according to lipid abnormality.Another 10 normal control pedigrees (57 subjects) served as controls.We compared the routine lipid levels such as triglyceride (TAG),total cholesterol (TC),HDL-C and LDL-C and non-HDL-C between the groups.After stratification based on TAG level,we observed the relationship between LDL-C and non-HDL-C.Last we confirmed and analyzed the cut-off value of differential diagnosis between FHTG and FCHL with receiver operating characteristic (ROC) curve.Results The levels of TAG,TC,and non-HDL-C were significantly higher in the affected group of FHTG than in the non-affected group of FHTG and the normal group (P＜0.01 or P＜0.05).The levels of TAG,TC,HDL-C,LDL-C and non-tHDL-C wcrc significantly higher in the affected group of FCHL than in the non-affected group of FCHL and the normal group (P＜0.01 or P＜0.05).The levels of TAG were significantly higher (P＜0.01) while TC,HDL-C,LDL-C and non-HDL-C levels were significantly lower (P＜ 0.01 or P＜0.05) in the affected group of FHTG than in the affected group of FCHL.The association between LDL-C and non-HDL-C was positive both in FHTG and FCHL,but the relationship became weaker as TAG level increased.The cut-off value of LDL-C and non-HDL-C was 3.575 mmol/L and 4.525 mmol/L,respectively.Conclusion In addition to the routinely used lipid indexes,non-HDL-C may be a new index for differential diagnosis of FHTG and FCHL,and may be superior to LDL-C in this regard.

BACKGROUND: Beta-tricalcium phosphate (β-TCP)/alpha-calcium sulfate hemihydrate (α-CSH) artificial composite bone has a porous morphology and good biocompatibility, and it is helpful to improve the fusion rate in a spinal fusion model, which however has not yet been confirmed.OBJECTIVE: To investigate the preparation methods, biocompatibility and application effect of β-TCP/α-CSH composite bone in the spinal fusion model.METHODS: (1) Calcium sulfate dihydrate under certain conditions and at a proper temperature can be dehydrated to prepare α-CSH. Healthy bovine cancellous bone was decellularized, degreased and sintered under the certain condition and at the certain temperature to prepare β-TCP particles. Then, the β-TCP particles were dissolved in anhydrous ethanol, suspended, dried, and then used to prepare the β-TCP/α-CSH composite bone. Osteoblasts from the rabbit periosteum were co-cultured with the composite bone, and then cell morphology, adhesion and proliferation were observed. (2) Twenty New Zealand white rabbits were selected to make bilaterally posterolateral spinal fusion models of the multiple thoracic vertebrae, in which β-TCP/α-CSH composite bone was implanted into the left side (experimental group) and autogenous bone implanted into the right side (control group). The spinal fusion rate was compared between the two groups.RESULTS AND CONCLUSION: (1) Under the phase contrast microscope, a relatively small amount of L929 cells adhered to the composite bone after 3 days of co-culture, while the number of adherent cells became relatively dense. Under the scanning electron microscope, there were many crystalline particles on the surface of the composite bone,indicating a higher number of adherent cells on the composite bone surface. (2) The spinal fusion rate was increased at 4 weeks after implantation of β-TCP/α-CSH composite bone, which was significantly higher than that after implantation of autogenous bone (P < 0.05). (3) At 4 weeks after autogenous bone implantation, the bone trabecular bone was scarce and clumped, and newborn bone tissues and the boneless autograft bone were dominant. After 8 weeks after spinal fusion, the newborn bone tissues around the autograft were further increased. At 4 weeks after β-TCP/α-CSH composite bone implantation, there was no degradation of debris, but existed a few new bone tissues; at 8 weeks after implantation,the composite bone was surrounded by newborn bone tissues, and thickened trabecular bone and degradation of the composite bone were found. To conclude, the prepared β-TCP/α-CSH composite bone can achieve a higher fusion rate in the spinal fusion model.

Objective To discuss the value of combining superselective mesenteric angiography (SSMA)with methylene blue in-jection for localization of the Obscure Gastrointestinal Bleeding (OGIB).Methods 12 patients presenting with OGIB had preopera-tive localization of the bleeding site by SSMA.The microcatheter was remained inside the bleeding artery branch after angiography. Then the methylene blue was injected via the microcatheter for localization during exploratory laparotomy and the dyed intestine was then removed.Results The detected rate of bleeding sites by using preoperative SSMA was 100%.The lesions in total 12 patients were found quickly during the exploratory laparotomy.The length of the removed intestine was 9 -12 cm (median,10 cm).After followed up for 10-24 months (median,18 months),all patients with OGIB had no recurrence.Conclusion The method of SSMA combined with the use of methylene blue injection is a safe and effective procedure for the localization of OGIB and could be beneficial for increasing the surgical success rate of hemostasis.

BACKGROUND: To repair bone defect, histocompatibility, growing characteristics, biodegradation and repairing mechanism of nanometer need to be further studied in clinic. OBJECTIVE: To observe the growing characteristics and histocompatibility of nano-hydroxyapatite (Nano-HA) for repairing jaw defect of rabbits.DESIGN: Randomized grouping animal study.SETTING: Beijing Jishuitan Hospital and Stomatology College of Jiamusi University.MATERIALS: A total of 24 New Zealand rabbits, either gender, weighing 2.5-3.5 kg, were provided by Animal Experimental Center of Jiamusi University. The animal experiment had got confirmed consent from local ethic committee. Nano-HA was provided by Material Engineering College of Jiamusi University and dealt with routine hyperthermia/hypertension sterilization. In addition, hydroxyapatite was provided by Wuhan Industry University, and the diameter was 1.0-2.0 μm.METHODS: The experiment was carried out in the Experimental Animal Center of Jiamusi University from November 2001 to May 2006. All rabbits were randomly divided into experimental group and control group with 12 in each group. Bone defect in the diameter of 1.0 cm was produced on body of mandible. Nano-HA was used to repair the bone defect of rabbits in the experimental group, while hydroxyapatite was used to repair the bone defect of rabbits in the control group. At 1, 4, 8 and 12 weeks after operation, all rabbits were sacrificed. In addition, medical imaging analysis system was used to analyze generative quantity of tissue in the two groups; meanwhile, histological quality and quantity were also analyzed so as to observe histocompatibility and newborn osteogenesis. MAIN OUTCOME MEASURES: Histocompatibility and newborn osteogenesis.RESULTS: With the time passing by, the amount of repairing materials was decreased because of the combination with newborn tissue into bone in bone defect-repaired region in the experimental group. When it was closed to normal bone, the amount was stable. However, bony callus was not able to grow in materials in the control group. Results of correlation analysis demonstrated that materials were negatively straight-line correlation with newborn bone (r = -0.912 0, P < 0.01). During the repairing procedure of bone defect, newborn bone was closely correlative with Nano-HA; while, with the increase of newborn bone, the amount of repairing materials was decreased because of the combination with newborn tissue into bone.CONCLUSION: Nano-HA can combine with newborn bone tissue so as to rapidly generate bone, while it has an excellent biocompatibility.
