BACKGROUND:There is a lack of study on material properties and parameters of foot finite element models in China. Vernier caliper is a common method for measuring the width and thickness of ligaments and tendons to calculate the cross-sectional area.
OBJECTIVE:To design a new ligament cross-sectional area measuring instrument to improve the measurement accuracy.
METHODS:The cross-sectional area of the five fresh cadaver ankle ligaments was respectively measured using the new instrument and vernier caliper, and then a comparative analysis of the two measurement methods was performend.
RESULTS AND CONCLUSION:The cross-sectional area of anterior talofibular ligament, calcaneofibular ligament, tibionavicular ligament and calcaneotibial ligament was (20.61±7.52), (22.38±11. 49), (33.09±9.91) and (28.20±10.88) mm2, respectively measured by the vernier caliper, and (17.59±4.03), (20.77±7.91), (28.08±8.14) and (30.39±7.98) mm2 by the new ligament cross-sectional area measuring instrument. These results suggest that this new measuring instrument is accurate, reliable and easy to operate, which can be used as a special instrument to measure ligament cross-sectional area, but further studies wil be necessary.

Chlamydial infection in human urogenital tract induces inflammation and causes tissue damage and scarring. It is thought that cytokine production by the Chlamydia-infected cells plays a key role in chlamydial disease processes. Although many cytokines have been detected during chlamydial infection, little is known about the molecular mechanisms on how Chlamydia triggers and sustains the inflammatory cytokine cascades. In the current study, chlamydial infection of the human cervical epithelial cell line HeLa cells can induce the production of IL-8, IL-1α, IL-1β and IL-6. Using inhibitors for probing intracellular kinase signaling pathways required for the Chlamydia-induced cytokines, it was found that the Chlamydia-activated MAPK / P38 pathway is required for the chlamydial induction of IL-1α and IL-6 while both the Chlamydia-activated MAPK/ERK and MAPK/P38 pathways contribute to the production of IL-8.

Objective To investigate the effects of diallyl disulfide (DADS) on ceil proliferation in human small cell lung cancer H446 cells in vitro. Methods MTT assay was used to observe inhibitory effect of DADS on proliferation of H446 cells. Cell Proliferation in-hibition was measured by growth curve analysis, average doubling time, vitality detection and MT]" assay. Cell morphology was observed by inversion microscope and optics microscope. Cell apoptosis was analyzed by cell morphology observed under light microscope, flow cytometry (FCM). Results MTT assay showed that DADS from 4 to 60 μg/ml significantly inhibited t446 ceils and exhibited a dose-dependent and time-dependent model. After exposure to DADS, H446 cell average doubling time retarded from 25. 40 hours to 145. 64 hours( P＜0.05).Flow cytometry analysis revealed that the cell content of C0-phase declined, however, hypodiplod peak was increased, which means cell ap-optosis were induced by DADS. Conclusion DADS could significantly inhibit the proliferation of H446 cells and induce the apoptosis of H446 cell.

Objective To investigate the effect of parecoxib on cardiac function after acute myocardial infarction (AMI) in rats. Methods Twenty-four adult male SD rats, weighing 230-250 g, were randomly divided into 3 groups ( n = 8 each): group Ⅰ sham operation (group S), group Ⅱ AMI and group Ⅲ parecoxib (group P). Myocardial infarction was induced by ligation of left anterior descending branch (LAD) of coronary artery in group Ⅱ and Ⅲ . In group S, LAD and cervical sympathetic trunk were exposed but not ligated and transected.Group P received intrperitoneal parecoxib 8 mg/kg once a day for 3 days 24 h after ligation of LAD, while group AMI received normal saline instead. At 4th day after ligation LAD, the left ventricular systolic pressure ( LVSP),left ventricular end-diastolic pressure (LVEDP) and ± dp/dtmax were measured and recorded. Blood samples were taken from common carotid artery to determine the plasma concentrations of TXA2 and PGI2 and PGI2/TXA2 was calculated. Then the animals were sacrificed and hearts removed. Myocardial infarct size of left venicle was calculated. Results Compared with group S, LVSP, ± dp/dtmax, plasma concentrations of PGI2 and PGI2/TXA2 were significantly decreased, while LVEDP and plasma concentrations of TXA2 increased in group AMI and P( P ＜0.05). Compared with group AMI, LVSP, ± dp/dtmax, plasma concentrations of PGI2 and PGI2/TXA2 were significantly decreased, while LVEDP and plasma concentrations of TXA2 increased in group P ( P ＜ 0.05). There was no significant difference in myocardial infarct size between group AMI and P (P ＞ 0.05). Conclusion Parecoxib can improve cardiac function after AMI in rats and the mechanism is related to regulation of the balance of PGI2/TXA2.

Objective To observe the changes of the quality of life in type 2 diabetes accompanying subclinical atherosclerosis and explore the effect of diabetic macrovascular complications in the quality of life.Methods One hundred and thiry-six type 2 diabetes were measured carotid intima media thickness (IMT) and then divided into AS group(n =51) and CON group(n =85).Two groups were examined with Special of Quality of Life for Diabetes Mellitus (DSQL).Plasma glucose,plasma insulin,glycosylated hemoglobin(HbA1c),high sensitivity C-Reactive Protein (hs-CRP) as well as insulin resistance index (HOMA-IR) and body mass index (BMI) were observed.Results The scores of DSQL and all domains had obvious difference between AS group and control group(P ＜0.05 orP ＜0.01) ;Relative to the control group the AS group was significantly increased BMI,HbA1c levels,hsCRP levels.The DSQL was associated with IMT,BMI,HbA1c,hsCRP,HOMA-IR.Conclusion The diabetic macrovascular compliations might result in impaired quality of life,which is associated with hyperglycemia,insulin resistance,inflammation,and central obesity.Psychotherapy and health education are very important for the improvement the DSQL in type 2 diabetic accompanying subclinical atherosclerosis.
