Objective To observe the anatomical and biomechanieal properties of the forearm in terosseous membrane (IOM), providing the scientific theoretical basis for the diagnosis and treatment of the IOM injury. Methods Ten radius-IOM-ulna structures (left for 5 and right for 5) were harvested from 5 fresh-frozen adult cadavers to measure the length, width and thickness of the tendinous part. Then the tendi-nous part with its radial and ulnar insertions were isolated, embedding the proximal part of the radius and the distal part of the ttina in commercially available dental base acrylic resin powder. The embedded speci-mens were mounted on MTS 858 testing machine using a 10 000 N load cell for all tensile tests. The speci-mens were tested at a displacement rate of 50 mn/min until failure. The load-displacement curve was de-scribed by the computer while the maximum load and stiffness were recorded. Results The IOM consisted of three components: the tendinous part, the membranous part, and the dorsal oblique accessory cord. The IOM was fiat in the neutral position, while it flexed during the pronation and supination. Six specimens ob-tained the tear of tendinous portion at a maximum load of (1021.50±250.13) N. The stiffness was (138.24±24.29) N/mm with displacement to failure of (9.77±1.77) mm. Other 4 specimens failed by fracture through the ulnar fixed site before there was failure of the IOM at a maximum load of (744.40±109.85) N. The stiff-ness was (151.17±30.68) N/mm with displacement to failure of (6.51±0.51) ram. Conclusion The IOM has stiffness comparable to the ligament between the radius and the ulna and play an important role for the maintenance of longitudinal stability of the forearm. These results can provide objective criteria for the eval-uation of reconstructive methods.

Objective To analyze and compare the clinical characteristics and therapeutic effects on pediatric patients with immune thrombocytopenia (ITP) among infants and children more than 3 years old.Methods The data of 1 015 ITP children who were hospitalized in West China Secondary Hospital of Sichuan University between January,2005 to January,2012 were collected.All of the patients were given hormone shock treatment and/or intravenous immunoglobulin (IVIG).According to the extent of platelet count and bleeding improvement,the outcome included complete response,response and no response.The patients were divided into the infant group(≤3 year old) and the elderly group (＞3 years old) based on age,acute group(≤6 months) and chronic group(＞6 months) based on the course of disease,their clinic data were retrospectively analyzed by software SPSS 12.0.Results (1) The male/female ratio of infants group was higher than that of the elderly group,and there was significant differences (57.1％ vs 45.3％,x2 =13.927,P ＜ 0.001).(2) The median platelet count on admission in the infant group was statistically higher than that of the elderly group(9 × 109/L vs 8 × 109/L,Z =2.448,P =0.014).The course of disease in the infant group was statistically shorter than that in the elderly group(7 d vs 75 d,Z =13.317,P ＜ 0.001).(3) The increase ratio of megakrocytes in infants group was lower than that in the elderly group,but no statistical differences were found (86.4％ vs 90.4％,x2 =2.534,P =0.111).(4) There was a significant difference in terms of hospital stays between the transfused patients and untransfused patients (6.5 d vs 7.1 d,Z =4.571,P ＜ 0.001).Under the same treatment,the time for the platelets to become normal in the transfused group was statistically lower than that in the non-transfused group (72 h vs 89 h,Z =4.116,P ＜ 0.001).(5)The time needed for the platelets to become normal (≥ 100 × 109/L) in the infant group were statistically lower than that in the elderly group(72 h vs 95 h,Z =6.540,P ＜0.001).(6)The ratio of chronic patients in the infant group was statistically lower than that in the elderly group (3.2％ vs 30.1％,x2 =178.42,P ＜ 0.001).Conclusions The male infants with ITP are more than the female and the course of disease is shorter.The infants' platelet count returns to normal faster,with better treatment efficacy and lower ratio of chronic patients.The hospital stays can be shortened in the patients with ITP who were transfused with platelets,but the course of treatment with hormone can not be shortened.

Objective To explore the effect of the meteorologic factors on air pollution in the summer in Xian, China. Methods The data of SO2?NO2 and PM10 concentrations in the air and the related meteorologic factors [maximum temperature(tmax), minimum temperature(tmin), average air pressure(P) and relative humidity(H)) from April 1st to June 30th in 2005 were collected. The correlation between the air pollutant level and related meteorologic factors was analyzed by the elements time diagram and multiple regression models with SPSS 11.0 software. Results A significant correlations between the meteorological elements and air pollutants was seen, the regression models for air pollutants were as follows, lnSO2=-3.352+0.019 tmax-0.026 tmin, lnNO2=-3.448-0.003H+0.012 tmax-0.015 tmin and lnPM10=-2.197+0.011 tmax-0.021 tmin. Conclusion The meteorologic factors have some effects on the air pollution levels and then impact human health in some degree.

OBJECTIVE:To investigate the effects of triptolide(TP)on the proliferation of fibroblast-like synoviocytes(FLS) from patients with rheumatoid arthritis(RA)in vitro. METHODS:5 RA patients received knee arthroplasty or synovectomy to ob-tain synovial tissue. FLS was isolated,cultured and identified,and then incubated in the presence of TP [0 (blank control),50, 100 and 200 nmol/ml] for 24,48 and 72 h. The effects of TP on FLS was evaluated by MTT,and then proliferation inhibitory rate was calculated;flow cytometry was used to detect the apoptosis and cell cycle of FLS. RESULTS:The inhibitory rates of TP(50, 100 and 200 nmol/ml)on the proliferation of FLS were 17.46%-52.56%,which was positively correlated with drug concentration. Compared with blank control group,100 and 200 nmol/ml TP could increase the percentage of cells in G0/G1 phase and decrease the percentage of cells in S phase,with statistical significance(P<0.05);200 nmol/ml TP could induce cell apoptosis. CONCLU-SIONS:TP could inhibit the proliferation and also could induce the apoptosis of FLS in RA patients in vitro,which may be one of its mechanism for treating RA.
