Chinese Journal of Tissue Engineering Research 2009;13(39):7785-7789
The present study retrospectively analyzed 23 patients with ulnar fracture or bone nonunion who received treatment in the Department of Orthopedics, Second Affiliated Hospital of Soochow University between August 2001 and December 2008. These patients comprised 16 males, 7 females, and averaged 41.8 years old (range 20-72 years old). Of them, 14 had single ulnar fracture, 6 had monteggia fracture, 19 had fresh fracture, 1 had obsolete fracture, and 3 presented with bone nonunion and plate breakage following ulnar fracture. All patients received interlocking intramedullary nailing. Internal fixation time and the mean time to fracture healing were recorded. The function of nailed forearm was evaluated using Anderson criteria. All 23 patients were followed up in terms of intra- and post-operative complications for a period of 6 months -7.3 years. Following Hertel classification criteria, bone union occurring at a mean of 14.7 weeks was found in 23 patients. No intramedullary nail loosening, fragmentation, or incision infection was observed. Twenty patients had intramedullary nails removed but did not present recurred fracture. According to the Anderson evaluation criteria regarding forearm functions, the results were excellent in 22 patients and satisfactory in 1 patient. These findings indicated that interlocking intramedullary nailing for treatment of ulnar fracture provides less trauma, short recovery period, and low recurrence. For these advantages, it is suitable for treatment of ulnar shaft fracture, multi-segment ulnar fracture, bone defects, bone non-union, and the fractures failed after compression plating; in addition, it is a better choice in treating ulnar fracture in patients with severe soft tissue injury or osteoporosis.

BACKGROUND: Autogenous bone has been used in cervical vertebra graft bone fusion in earliest stage and at most. However, its source is limited, simultaneously, induced many complications such as infection, hemorrhage and postoperative pain in the donor bone region. Recently, above-mentioned complications were avoided or reduced with the usage of new graft bone fusion material. OBJECTIVE: To compare clinical efficacy using MC+~R combination of autogenous bone or calcium sulfate artificial bone in antador cervical fusion.METHODS: A total of 26 patients (34 levels) with cervical spondylotic myelopathy underwent anterior cervical discectomy and cervical intervertebral fusion from January to December 2008. Anterior cervical oblique cut was 3.0-4.0 cm. The endplate were preserved after the cervical intervertebral disc and the posterior longitudinal ligament were removed. Autogenous bone group was filled with autogenous bone. Calcium sulfate artificial bone group was filled with Wdght's Osteoset artificial bone. Anchoring clip was implanted between the cervical vertebrae. Every patient had a short neck incision was assessed with X-ray, JOA grade and Odom's evaluation scale.RESULTS AND CONCLUSION: The two groups of 26 patients (34 segments)were followed up. The JOA score of postoperation was no significant difference between the two groups. According to the Odom's evaluation scale, the excellent and good rate of calcium sulfate group was higher than autogenous bone group, but there was not statistical significance (P>0.05). The fusion rate of autogenous bone group was higher than calcium sulfate group at 3 and 6 months, but the fusion rate of two groups were 100% at 12 months. Although the calcium sulfate group at 6 months, lordosis angle lost more than 0.4°than the autogenous bone group,but no significant statistically between the two groups (P>0.05). MC+ combination of autogenous bone or Calcium sulfate had the same clinical efficacy in the treatment of cervical spondylotic myelopathy, but the calcium sulfate artificial bone could be effectively avoided the complications of donor site.

Occupational therapy, as one of the important subdisciplines of rehabilitation therapy, takes occupational activities as the medium or purpose of treatment and life participation as the goal of treatment to meet the growing demand for rehabilitation. According to the Minimum Standards for the Education of Occupational Therapists developed by the World Federation of Occupational Therapists, many countries and regions have formulated educational standards that meet their own national or regional characteristics. Comparatively, the number of occupational therapists is seriously insufficient, the talents cultivation is relatively lagging behind, and the education level is uneven in mainland China; while in Hongkong and Taiwan, occupational therapy has an independent education system and a relatively mature talent training model. This study summarized the practical experience and reviewed the relevant literature. Based on the summary and review, we made a comparative analysis of postgraduate education in mainland China and Taiwan from the aspects of educational system and accreditation, enrollment objects, curriculum setting and teaching methods, which would provide a reference for the improvement of occupational therapy personnel training system in mainland China.

Objective To study the correlationship between type Ⅰcollagenα1 (COL1A1) gene polymorphism and the occurrence of osteosarcoma. Methods Peripheral blood from 54 patients with osteosarcoma and 126 normal ones were collected, rs1061970 genotype of COL1A1 gene was amplified with PCR and products were analyzed by pyrosequencing among the samples. Results The allele frequency of TT (13.0%) and CT (48.1%) was significantly higher in pathologi-cal group than that in the normal control group, which manifested a allele frequency of TT(11.9%) and CT(30.2%) (P<0.05). Additionally, allele frequency of T in patients with osteosarcoma was 37.0%, higher than the control group (27.0%), with OR of 1.59 and 0.99-2.57 of 95%CI, with no difference of statistically significant (P>0.05), but the risk was still on the rise of osteosarcoma. Conclusion COL1A1 gene polymorphism may be related with the incidence of osteosarcoma, patients who carry the T allele of gene of COL1A1 may increase the risk of osteosarcoma occurrence.

Objective:To evaluate the effect of zoledronic acid administration for osteoporotic vertebral compression fracture (OVCF) after treatment with percutaneous kyphoplasty (PKP).Methods:A retrospective case-control study was performed on 430 elderly patients with OVCF admitted to the Second Affiliated Hospital of Soochow University from January 2012 to December 2016. There were 31 males and 399 females, with age of 52-92 years[(72.8±8.3)years]. Fracture segments were at T 5-T 10 (82 vertebrae), T 11-L 2 (389 vertebrae) and L 3-L 5 (173 vertebrae). In zoledronic acid group ( n=178), patients were given zoledronic acid 3 days after PKP surgery. In basic treatment group ( n=252), patients were only given basic treatment after PKP surgery. Bone mineral density was measured before operation and one year after operation. Visual analogue scale (VAS) and Oswestry disability index (ODI) were assessed before operation, 3 days and one year after operation. Incidence rate of refracture, mortality and complication rate were recorded after operation. Results:All patients were followed up for 12-60 months (mean, 27 months). Before operation and at postoperative 1 year, the vertebral bone mineral density in zoledronic acid group was (-2.3±1.5)SD and (-1.2±2.3)SD ( P<0.05), and that in basic treatment group was (-2.2±1.2)SD and (-2.1±1.1)SD ( P>0.05). At postoperative 1 year, the bone mineral density in zoledronic acid group was significantly better than that in basic treatment group ( P<0.05). At preoperative 3 days, postoperative 3 days and postoperative 1 year, the VAS was (8.6±0.8)points, (2.8±0.8)points, (2.1±0.8)points in zoledronic acid group, and was (8.5±1.1)points, (2.9±0.9)points, (3.0±2.3)points in basal treatment group; ODI was 48.7±5.3, 24.0±2.9, 22.3±3.3 in zoledronic acid group, and was 48.3±6.1, 24.5±3.8, 27.6±4.0 respectively in basal treatment group. The VAS and ODI were significantly reduced in two groups at postoperative 3 days and 1 year compared to those before operation ( P<0.05). Moreover, the VAS and ODI in zoledronic acid group were significantly lower than those in basal treatment group at postoperative 1 year ( P<0.05). At postoperative 2 years, the incidence rate of refracture in zoledronic acid group was 10.1%(18/178), significantly lower than 16.7%(43/252) in basic treatment group ( P<0.05). Mortality rate in zoledronic acid group was 5.1%(9/178), and that in basic treatment group was 6.3%(16/252) ( P>0.05). No serious complications were observed in both groups such as nerve injury or pulmonary embolism. Conclusion:For OVCF patients, zoledronic acid given after PKP can improve the bone mineral density, reduce pain, fasten function recovery, and effectively decrease the refracture rate.

Malic acid is widely used in food, and chemical industries. Through overexpressing pyruvate carboxylase and malate dehydrogenase in pdc1-deficient Saccharomyces cerevisiae, malic acid was successfully produced through the reductive TCA pathway. No malic acid was detected in wild type Saccharomyces cerevisiae, however, 45 mmol/L malic acid was produced in engineered strain, and the concentration of byproduct ethanol also reduced by 18%. The production of malic acid enhanced 6% by increasing the concentration of Ca2+. In addition, the final concentration reached 52.5 mmol/L malic acid by addition of biotin. The increasing is almost 16% higher than that of the original strain.
