[Objective]To evaluate surgical outcomes of hemivertebra resection only via posterior approaches followed by short-segment transpedicular instrumentation for correction of the congenital scoliosos. [Method]A group of patients with a single hemivertebra between the ages 5-16 years who underwent operative treatment were evaluated.Hemivertebra resection through posterior approach and short-segment transpedicular instrumentation were used for correction of the scoliosis and kyphosis deformities.Radiographic evaluation were conducted before and after operation and at follow-up visits.Cobb's angles of the segmental curve,total main curve,cranial and caudal compensatory curves and kyphosis were measured on the posteroanterior and lateral radiographs.[Result]The cases in this study showed satisfied results.The mean Cobb's angle of segment curve was 41.5? before surgery and 15.1? after surgery with a 63.6% correction,and 14.7? at the lastest follow-up assessment with a 64.6% correction;total main curves improved from 46.9?to 18.4?,with a 60.8% correction;17.5?at last follow-up,with a 62.7% correction;the correction ratio for kyphosis was from 15.4?kyphosis to normal physical profile;cranial and caudal compensartory curves were obviously improved.[Conclusion]Hemivertebra resection and short-segment transpedicular instrumentation could be performed only through posterior approach,which had exerted satisfactory correction on congenital scoliosis.If the operation is performed before the maturity of the bone,it will effectively prevent the formation of secondly spinal deformities.

Objective To investigate the efficacy of transcutaneous injection of MIIGX3 artificial bone and methylprednisolone for recurrent bone cysts.Methods From January 2004 to March 2006,a total of 13 children with recurrent bone cysts received transcutaneous injection of methylprednisolone and MIIGX3 in our hospital.X-ray was employed to detect the degradation of MIIGX3 and formation of new bones.Results The operation time ranged from 30 to 95 minutes(mean 42 minutes).The patients were followed up for 1 to 3 years.None of them had recurrence of bone cysts during this period.The artificial bones were completely degraded and replaced by new bones in 1.5 years after the injection.Conclusions Transcutaneous injection of methylprednisolone and MIIGX3 is effective for recurrent bone cysts.Patients have shorter operation time and hospital stay after this treatment because the procedure is microinvasive.

Objective To evaluate the clinical effect of deep acupuncture at Lianquan (CV23) combined with swallowing rehabilitation training in the treatment of dysphagia after stroke.Methods A total of 84 patients with dysphagia after stroke who met the inclusion criteria were divided into 2 groups, 42 in each. The control group received swallowing rehabilitation training, and the observation group was treated with acupuncture therapy based on deep acupuncture atLianquan (CV23) combined with swallowing rehabilitation training. The VFSS score and clinical efficacy were compared between the 2 groups before and after treatment.Results The cure rate of observation group was 69.1% (29/42), the total effective rate 85.7% (36/42), while the control group were 42.86% (18/42) and 66.67% (28/42). The comparison of cure rate and total efficiency rate between the two group had statistically significant differences (χ2=5.845, 4.200,P=0.016, 0.040). After treatment, the VFSS score of the observation group was significantly higher than that of the control group (7.43 ± 2.27vs.4.31 ± 1.53;t=5.433, P<0.05). The recovery time of the 29 cured patients in the observation group was (12.0 ± 3.0) d, while the recovery time of the 18 cured patients in the control group was (17.8 ± 2.2) d. There was statistically significant difference between the 2 groups (t=7.094,P=0.001).Conclusions Deep acupuncture at Lianquan (CV23) combined with swallowing rehabilitation training can improve the swallowing function of patients with dysphagia after stroke, shorten the recovery time of swallowing function and improve the clinical efficacy.

The necessity and superiority of the surgical operation on children with floating knee injury and the fracture union and complications were investigated. Twenty-eight children with floating knee injury were subjected to open reduction and internal fixation or external fixator. The patients were followed up for 18 months to 7 years. The curative effectiveness was scored by Karlstrom criteria. The results showed that no nonunion or deformity was found. The affected limb was 1.2 cm to 1.5 cm longer in 2 cases, 0.8 to 1.2 cm shorter in 3 cases than the contralateral. No severe dysfunction of knee joint occurred. The excellent-good rate was 92.8% and the curative rate 71.4% respectively. So for children whose age is older than 5 years, it's a good way to treat the fractures of femur and tibia with open reduction and internal fixation or external fixator. The method can be advantageous for the nursing care, early function recovery, shortening of the hospital stay and avoidance of severe complications.

BACKGROUND:There are several reports about the application of fresh bone marrow aspirate being injected directly to repair partial ligament injury, but the application about fresh bone marrow aspirate directly being planted on scaffolds to build tissue-engineered ligament is rarely mentioned.
OBJECTIVE:To evaluate the feasibility of applying fresh bone marrow aspirate planted directly on scaffolds to construct tissue-engineered ligament
METHODS:We constructed fibroin fiber/smal intestinal submucosa composite scaffold, then planting fresh bone marrow directly to built bone marrow seeding group and planting seed cel s (bone marrow mesenchymal stem cel s) on the scaffold to built cel seeding group. The control group had no treatment. After that, we detected the density of cel adhesion, cel proliferation ability and extracel ular matrix secretion. Then, the composite in the bone marrow seeding group was implanted into the broken anterior cruciate ligament in rabbits, and material biocompatibility in vivo was evaluated after 12 weeks.
RESULTS AND CONCLUSION:After 4 hours of incubation, bone marrow seeding group was significantly higher than the cel seeding group in cel adhesion density and proliferation rate (P<0.05). Bone marrow seeding group and cel seeding group showed higher type I, III col agen secretion compared with the control group (P<0.05), but the col agen secretion of bone marrow seeding group and cel seeding group showed no significant difference. Composite cel scaffold implantation in vivo did not cause fatal immune rejection and severe inflammatory reaction, and no significant ligament regeneration and vascularization occurred. These findings indicate that fresh bone marrow aspirate can be seeded directly on scaffolds to construct tissue-engineered ligament, and the short-term biocompatibility in vivo is good.

BACKGROUND: The cells of biomaterial compound cytokine gene or compound transfected cytokine gene that are transplanted into the area of bone defect can promote bone repair.OBJECTIVE: To investigate the feasibility of gene therapy for bone defect after rat transforming growth factor (TGF)β1 gene is transfected into osteoblasts.DESIGN: A controlled and observational experiment.SETTING: Department of Orthopedics, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology.MATERIALS: Five newborn Sprague-Dawley rats of either gender were included.METHODS: The experiment was conducted in the laboratory of Orthopedic Department, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, from February to September 2000.Rat osteoblasts were transfected with pcDNA3-TGF-β1 plasmid by lipofectamine mediated gene transfer, and the plasmid pcDNA transfected cells were set as control group. The transient expression of TGF-β1 was detected by strept avidin-biotin-peroxidase complex (SABC) method and in situ hybridization detection 24 hours later. The cells transfected by G418 for 2 weeks were detected with SABC to investigate the stable expression of TGF-β1 gene.MAIN OUTCOME MEASURES: SABC method and in situ hybridization detection were applied to detect gene expression.of pcDNA3-TGF-β1 transfected osteoblasts and in situ hybridization detection: After the osteoblasts were transfected for 24 hours, cytoplast was full of brown granules and there were no brown granules in the cytoplast of blank carrier transfected cells, indicating that TGF-β1 mRNA was signifiG418: transfected cells still had high expression of TGF-β1 after 2-week G418 screening.CONCLUSION: Osteoblasts can express cytokine immediately with high effect using gene transfection technique. The stable and high expression is presented after TGF-β1 gene is transfected into osteoblasts at the moment of transfection and after 2-week screening, proving the feasibility of gene therapy for bone defect when cytokine gene is transfected into osteoblasts.

OBJECTIVETo observe the clinical efficacy of deep acupuncture at Lianquan (CV 23) and Yifeng (TE 17) combined with swallowing training for post-stroke dysphagia.

METHODSSixty cases of post-stroke dys phagia were randomly divided into an observation group and a control group, 30 cases in each one. Patients in the observation group, based on the regular acupuncture treatment, were treated with deep acupuncture at Lianquan (CV 23) and Yifeng (TE 17), once a day, 30 min per treatment; also swallowing training was combined, twice a day, 20 min per treatment. Patients in the control group were treated with swallowing training. All the patients were treated with regular treatment of stroke. Six days of treatment were taken as one session, and totally 3 sessions were given with an interval of one day between sessions. The video fluoroscopic swallowing study (VFSS) dysphagia evaluation scale and Watian water swallow test (WWST) were evaluated before and after treatment also the clinical efficacy and the recovery time of two groups were compared.

RESULTSAfter treatment, the VFSS score in the observation group was significantly superior to that in the control group (P < 0.01); the WWST in the observation group was significantly superior to that in the control group (P < 0.01). The cured rate was 70.0% (21/30) in the observation group, which was significantly superior to 43.3% (13/30) in the control group (P < 0.01); the total effective rate was 86.7% (26/30) in the observation group, which was significantly superior to 66.7% (20/30) in the control group (both P < 0.01). The clinical recovery time in the observation group was significantly shorter than that in the control group (P < 0.01).

CONCLUSIONDeep acupuncture at Lianquan (CV 23) and Yifeng (TE 17) combined with swallowing training could effectively improve post-stroke swallow function.

This study examined effect of a new intervertebral cervical disc prosthesis in relieving the neurological symptoms and signs, improving the patients' ability to perform daily activities, reducing pain, and maintaining the stability and segmental motion. From December 2003 to October 2004, 12 patients, who had received 14 replacements of cervical artificial discs, were followed-up for 2 to 8 months (with a mean of 5.2 months). Of them 5 had cervical spondylotic myelopathy and 7 had cervical disc herniation. The patients included 7 males and 5 females, with their age ranging from 35 to 62 y and a mean of 50.3 y. Single-level replacements were performed in 10 cases and 2 cases received two-level replacement. Operation time of the single-level surgery averaged 130+/-50 min and the time of two-level surgery was 165+/-53 min on average (from skin incision to skin suturing). Neurological or vascular complications during or after surgery was not observed. Japanese Orthopedic Association scores (JOA scores) increased from 8.6 to 15.8 on average. There was no prothesis subsidence or excursion. Replaced segments were stable and the range of motion was partially restored, being 4.68 degrees (3.6 degrees -6.1 degrees ) in flexion and extension position and 3.51 degrees (2.5 degrees -4.6 degrees ), 3.42 degrees (2.6 degrees -4.3 degrees ) in left and right bending position. No obvious loss of physiological curvature was noted. CT or MRI follow-up showed that excursion was less than 1.5 mm) in 2 of 14 levels and between 1.5 mm and 3 mm) in 1 of 14 levels. No ossification in the replaced levels was observed. It is concluded that satisfactory short-term results were achieved in the 12 cases of artificial disc replacements. Different from anterior cervical discectomy and fusion, the replacement could achieve quick functional recovery and did not lead to the movement limitation of cervical vertebrae. At least a 5-years follow-up was needed to assess the long-term effect of the prosthesis on its neighboring segments.

To investigate the efficacy of a combination therapy on gluteal muscle contracture, 286 definitely diagnosed patients were subjected to surgical treatment, and then functional exercises and physical therapy. The patients with severe symptoms were asked to have a set of specially-designed functional exercises. All the patients were followed up for 3 to 24 months by hospital visit, correspondence or telephone interview. The effective rate was 100%, and the curative rate was up to 94.6%. Few patients developed complications and relapse was rare. It is concluded that the combination therapy, including surgical removal of diseased tissues, functional exercises and physical therapy, is an effective approach for the treatment of severe juvenile gluteal muscle contracture.
