[Objective] To investigate the treatment in the use of allograft bone grains combined with autograft bone grafting in giant cell tumor.[Method]From March 1996 to March 2006,24 cases of giant cell tumor closed to knee were verified by pathology in this department,including 11 on thighbone and others on tibia.Before operation allografts was sheared to grains after antigen extracted by repeat freeze thawing and mechanical methods.Giant cell tumor of bone was completely erased in surgical fringe and the defect was thoroughly closed-up with allograft grains combined with cancellous bone autografts.The knee joints exercise was made for 12 weeks with external orthosis fixation.[Result]No severe complication occurred in early stage after operation in the 24 patients.All of them were followed up for 1 to 6 years with an average of 2 years and 8 months.None of them recidivated after the operation,and no insert was taken off for severe rejection,one case showed tolerant pathologic fracture.All the transplantations showed ideal appearance in X-ray photograph and the motion of joints had no significant difference than before.Curative effects were evaluated by Mankin criteria.The outcome was excellent in 20 cases,good in 4 cases.[Conclusion]Bone allograft grains combined with autograft is an effective and few rejection in filling of giant bone defect in surgical operation of giant cell tumor near knee joints.

[Objective]To explore the incidence, causes, training courses at high risk and location of the body of training injury in a special force corps, provide evidence for effective prevention of the injury.[Method]A questionnaire on training injuries and relative situations, and review of medical records from Nov 2005 to Oct 2006 were performed in 823 soldiers and officers in a special force corps at Nov 2006. Data were input into computers after quantization, and descriptive analysis was conducted with SPSS 13.0 software. [Result]Of 823 soldiers and officers, 738 (89.67%) experienced one or more injuries in that year, 525 (63.79%) were affected in normal training, 221 (26.85%) lost more than one training day due to the injuries. Confirmed with the medical records, 213 (25.90%) lost more than one training day due to injuries. A total of 1696 injuries occurred in 823 soldiers and offices in that year, of them, 1263 injuries interfered with normal training. Injury rate was 12.78 per 100 per month. 24.12% of injuries were due to over-exertion, 15.86% due to accident and 13.33% due to environmental field. Injury occurred mainly in runing related training courses including 5km running (22.17%) and 400m obstacle running (20.87%), followed by weight lifting (9.67%). The most frequent site of injury was the lower extremities, accounted for 65.74 % of the inj urie s including the foot ( 18.75 %),the ankle (13.50%), the leg (13.56%) and the knee (14.39%), followed by low back (14.21%). [Conclusion]Persistent over-exertion basic training, the courses at high risk of injury, should be improved in focus. Lower extremities and low back, the most frequent locations of injury, should be taken as key points of prevention and treatment of training injury.

Study on the changes of osteophiphysis observed on the X ray film is quite practical for the age estimation of male teenager.210 male teenager cases,13～20 years old,from North China were studied for age estimation.Radiographic plates were taken from the following articles:shoulder joint,elbow joint,wrist joint,hipjoint,knee joint,ankle joint.Pedis 27 characteristics were found,phased and scored.By which the regression equations were constructed with SPSS.Four regression equations with highest multi relationship coefficient(r=0 758～0 787)and lowest standard error(SE=1 0136～1 0701)were then selected.The method presented here is quite useful for the age estimation of the teenage group in North China.

Objective To establish appropriate correction models of serum marker α -fetoprotein (AFP) multiple of the median (MOM) for prenatal screening on patients with neural tube defect (NTD) at the second trimester to replace the foreign data currendy used in Beijing with a higher sensitivity.Methods A sample of 5815 mid-gestation pregnant women with normal pregnancy outcome were selected including 5557 cases of age ＜ 35 years and 258 cases of age ≥35 years.The regression relationship between AFP median and gestational age was builded by exponential model and the regression relationship between MOM and weight was builded by power model in age ＜ 35 years.The regression relationship between AFP median and gestational age was builded by S model and the regression relation ship between MOM and weight was builded by quadratic model in age ≥35 years.The normal reference values in two age sections were estimated approximately by percentiles method.Results Corrected AFP MOM values with mean value (age ＜ 35 years:1.001; age ≥35 years:1.113) and median value (age ＜ 35 years:0.934;age ≥35 years:0.990) obtained by regression analysis were more close to 1.00 than the data from the software[mean value(age ＜ 35 years:1.164; age ≥35 years:1.254) and median value (age ＜35 years:1.093; age ≥35 years:1.149)].There were significant differences (age ＜35 years:t =65.120,P =0.000;age ≥35 years:t =9.812,P =0.000).Conclusion Correction model for maternal serum marker is more applicable for Beijing population at the second-trimester prenatal screening.

Objective To prepare anti-apoM monoantibodies with high affinity and high purity, and investigate apoM distribution among human tissues and different groups of people. Methods BALB/c mice were injected intracutaneously with recombinant apoM. After cytomixis, screening and cloning, we established a hybridoma, which grew well and steadily secreted antibodies. The ascites were acquired by injecting BALB/c mice intraperitoneally and anti-apoM monoantibodies were gained using standard techniques. We detected apoM levels in healthy individuals and the patients with coronary heart disease including stable angina (SA) group and acute coronary syndrome (ACS) group using the anti-apoM monoantibodies. ResultsThree anti-apoM monoantibodies were collected and confirmed after subtype identification and block test. The apoM protein were detected in some human cells and human tissues by these three monoantibodies. The concentration of apoM was (11.02 ±1.96) ×10 -3 g/L, (10. 76± 1.32) ×10-3 g/L, (12. 83 ± 2. 28) × 10-3 g/L in SA, ACS and control group respectively. There was significant difference within the three groups (F = 11. 544, P ＜ 0. 05). Comparing apoM concentrations among control group and coronary heart disease groups, it showed that the levels of apoM were lower in coronary heart disease groups than in control group(t =2. 962 and 3. 967,P ＜0. 05). There was no significant difference between two coronary heart disease groups (t = 1. 033, P ＞ 0. 05). Conclusion Anti-apoM monoantibodies are successfully raised and could combine with apoM in human cells and tissues. This lays the foundation for the apoM study in apolipoprotein metabolism.
