RESUMO
Objective: To observe the efficacy of Endobutton combined with the suture in the treatment of Meyers-Mckeever-Zaricnyj type IV tibial eminence fracture, and to explore the characteristics and treatment methods of Meyers-Mckeever-Zaricnyj type IV fracture. Methods: The clinical data of seven patients with Meyers-Mckeever-Zaricnyj type IV tibial eminence fracture were collected; the literature review was performed, and the surgical treatment methods, key points of operation and precautions of the patients were analyzed. Results: After arthroscopic debridement, 3 kinds of main fractures were found: anterior cruciate ligament connected fragment (ACLCF), anterior horn of lateral meniscus connected fragment (ALMCF), and posterior-medial cartilage connected fragment (PMCCF). The PMCCF was first fixed after pre-reduction from back to front and from deep to shallow orders, then the ALMCF and ACLCF were fixed, avoiding the secondary displacement and bone cutting. The follow-up periods of 7 patients were 6-12 months, with an average followed-up period of 7 months. The front drawer test (-), Lachman test (-); the average Lysholm score of patients before operation was less than that in the last follow-up period (P<0. 05). The knee joint stability of patients was good, and the knee joint had no movement disorder and infection. Conclusion: The intra-operative reduction order is crucial during the operation of Meyers-Mckeever-Zaricnyj type IV tibial eminence fracture. Perfect fixation can be achieved by using Endobutton combined with suture.

RESUMO
Objective To investigate the immunization effect of influenza A/H1N1 vaccine in health care workers (HCW) in Inner Mongolia Greater Khingan Mountains area. Methods Five hundred and five HCW who received A/H1N1 influenza vaccination (immunized group) and 129 staffs who didn't receive the vaccination (unimmunized group) were randomly sampled for semiquantitative testing of serum H1N1 antibody (IgG) levels by enzyme-linked immunosorbent assay (ELISA).Results were analyzed and stratified by age, sex, occupation and the time interval between the time of vaccination and serum sample collection. The antibody positive rates of the two groups were compared by x2test. Results There were 401 (79. 4%) HCW whose H1N1 antibody were positive and 50 (9.9%) whose antibody were weak positive among 505 immunized HCW. While among 129 unimmunized HCW, there were 59 (45.7%) whose antibody were positive and 15 (11.6%) whose antibody were weak positive. The seroconversion rates of specific antibody were not significantly different among the different age groups after receiving A/H1N1 influenza vaccine (P＞ 0.05).However, there were statistical differences of the seroconversion rates among different sex groups (men 95.7% vs women 87.4% in immunized group, x2=6.40, P＜0.05; and men 73.3% vs women 52.5% in unimmunized group, x2 =4.07, P＜0.05) and different occupation groups (doctor 86.0% vs nurse 94.5% in immunized group, x2 = 9. 16, P＜0.01; and doctor 43. 8% vs nurse 75.0% in unimmunized group, x2=12.61, P＜0.01 ). The seroconversion rate was 81.5% after 80 to 89 days of vaccination, which was significantly lower than those after 30 to 39, 50 to 59 days and 60 to 69 days of vaccination, which was 100.0%, 94.7% and 93.6%, respectively (x2 =3.96, P ＜0.05; x2=7.15, P ＜0. 01; x2 = 9. 98, P＜0. 01). Conclusions A/H1N1 influenza vaccination can induce effective immune response in HCW in Greater Khingan Mountains area of Inner Mongolia. However,the level of specific antibody significantly reduces after 80 to 89 days of vaccination.
RESUMO
Objective To construct the eukaryotic expression vector encoding IT15 gene and detect its expression in SH-SY5Y cells.Methods The exon1 of IT15 gene was amplified from genomic DNA isolated from a healthy adult and a Huntington disease patient lymphoblastoid cell lines by PCR.PCR products were subcloned into eukaryotic expression vector pEGFP-C1.The SH-SY5Y cells were transiently transfected with the recombinant plasmids and observed under fluorescence microscope.Western blot was used to detect the expression of the fusion protein.Results PCR products had approximately 170 and 310 bp specific segments.The recombinant eukaryotie expression plasmids were confirmed by restriction endonuclease analysis and sequencing.The N-terminal fragment of normal huntingtin primarily localized in the cytoplasim of SH-SY5Y cells,while the N-terminal fragment of mutant huntingtin aggregated both perinuclearly and intranuelearly.Conclusions The recombinant eukaryotic expression vectors encoding wild type and mutant IT15 gene fragments are useful for studying pathogenesis of Huntington disease.The Nterminal fragment of mutant huntingtin aggregats both perinuclearly and intranuclearly,which could be important for Huntington disease pathophysiology.

RESUMO
BACKGROUND: Osteoporosis is one of the complications of spinal cord injury, but its mechanism is unclear, different scholars have different points about whether all bones above and below the level of trauma are affected after spinal cord injury (SCI).OBJECTIVE: To observe the ultrastructure of bone tissue of secondary osteoporosis after spinal cord injury and the change of serum biochemical indexes, to analyze the suffered condition and injured degree of the bones above and below the level of the trauma.DESIGN: Randomized controlled experimentSETTING: Laboratory of Animals, and Department of Laboratory Medicine of the Second Clinical Hospital of Jilin University; Transmission Electron Microscope Center, Norman Bethune Division of Medical Sciences of Jilin UniversityMATERIALS: This experiment was conducted at the Laboratory of Animals, Second Clinical Hospital of Jilin University from May 2002 to May 2003. Totally 110 male Wistar rats, aged 4 to 5 month-old, with the body mass of (300 -320)g were involved.METHODS: Ten rats were randomly chosen from 110 male Wistar rats and were set as 0 week blank control group, the ther rats were randomly divided into experimental group and control group, there were 10 rats in week 1, 2, 3, 7 and 11 control group and experimental group separately.1 mL/L of pentobarbital natrium was intraperitoneal injected to perform anesthesia, in the control group, lamina with dura intact of rats were removed only, without spinal cord injury at the level of tenth thoracic vertebrae. In the experimental group, lamina of rats was also removed, the spinal cord injury model of the rats were made by the method of Allen's.4 mL venous blood was collected from the animals at the end of postoperative week 0, week 1, week 2, week 3, week 7 and week 11, then the animals were put to death, perform blood centrifuging .We observe the change of serum concentration of calcium, phosphorus and alkaline phophatase (ALP) with 7170A HITACHI auto-biochemistry analyzer. Right side humerus, tibia in week 0 blank control group, week 7 experimental group and week 11 experimental group were chosen, then 25 mL/L ethylene dinitrilotetraacetic acid was used for decalcium for 1 month for preparingthe sections. We observe the change of ultrastructure of osteocytes at the sites of tibial plateau and the surgical neck of the humerus after stained by uranyl acetate and lead citrate under transmission electron microscope.biochemistry detection: the level of phosphorus at week 2 of the experiment was significantly lower in the control group than experiment group [(1.54±0.21),(2.76±0.16)mmol/L, (P ＜ 0.01)]; the level of calcium at week 3 in the experiment group was significantly higher than in the control group [(2.52±0.06),(2.35±0.12)mmol/L, (P ＜ 0.01)];the level of alkaline phophatase at week 7 in the experiment group was significantly higher than in the control group [(155.86±20.42), (129.25±7.30)Nμ/mg,operative week 7, the tibia sample showed that the osteocyte separated from the osseous lacuna, the nucleus showed anomaly, fluffed materials appeared. Mitochondrion swelled, rough endoplasmic hollowed; At week 11, osteocyte separated from the osseous lacuna. At postoperative 7 week,the humerus sample showed that osteocyte separated from osseous lacuna,some nucleus pycnosis and rough endoplasmic hollowed; At postoperative week 11, the above changes still were seen, but the degree of cellular swelling and hollowing were lighten.CONCLUSION: At the early stage of spinal cord injury, the activity of osteoclast is increased and the activity of osteoblast is decreased, which leads to the increase of bone absorption, the bone formation is largely weakened. The bones above and below the level of trauma are both affected after spinal cord injury, but different extents of osteoporosis can be seen in different bones .The change of ultrastructure of osteocytes is remarkable when osteoporosis has happened.
