BACKGROUND:It is very nscessary for the prevention and treatment of ostaoarthritis(OA)to understand the tensile mechanical properties of lateral collateral ligaments(LCLs)of knee joints with osteoarthritis,while reports on it are still few.OBJECTIVE:To compare the LCL tensile mechanical property indexes of knee joints between normal animals and OA medels established for this purpose,and to provide qualitative and quantitative referential data about effects of OA on the LCL tensile mechanical properties of animal knee joints.DESlGN,TIME AND SETTING:A randomized controlled trial was finished at the Mechanical Expedmental Center of Jilin University from December 20th to 30th in 2008.MATERIALS:A total of 20 male SD rats of 6 months old were divided into a normal control group and a model group,with 10ones in each group.METHOOS:Rats in the model group were copied into OA models.after which test on tensile was performed to each of the ten rats in the two groups at the speed of 5mm/min on Universal Testing Machine,Shimadzu.Data obtained from the test were processed in polynomial though least square method.MAIN OUTCOME MEASURES:Tensile maximum load.maximum displacement,maximum stress,maximum strain and stress-strain curves.RESULTS:The tensile maximum load,maximum stress,maximum displacement and maximum strain in the normal control group and the model group were(12.754±2.795)N,(27.681±5.832)MPa,(2.754±0.707)mm,(11.679±2.373)%and (7.183±1.817)N,(16.162±3.403)MPa,(1.827±0.768)mm,(8.019±2.811)% respectively,from which we could see that each index in the normal control group was greater than that in the model group obviously (P＜0.05).CONCLUSION:The tensile maximum load,maximum stress,maximum displacement and maximum strain all decreased after OA,which indicates that osteoarthritis has certain effects on tensile mechanical properties of LCLs of knee joints as well as stress relaxation.

Objective To explore the most convenient and valid tool for screening mental disorders among servicemen. Methods Soldiers and officers stationed at Guilin were enrolled for the study. They were first examined with the Symptom Check-list 90 (SCL-90), Cornell Medicine Index (M-R)[CMI(M-R)], University Student Personality Inventory (UPI) and WHO neurosis screening schedule respectively. Then they were subjected clinical interview and examination individually, and clinical diagnosis of mental disorder was made according to CCMD-3 standard. The validity of each questionnaire was evaluated by using Criterion-related Validity. Results The sensitivity of WHO neurosis screening schedule was found to be 100%, and the specificity was 92.1%. SCL-90 and CMI (M-R) yielded similar results, their sensitivity was found to be 46.9% and 43.4%, and the specificity to be 86.1% and 78.9%, respectively. The sensitivity of UPI was found to be 83.1% and the specificity 46.1%. Conclusion The WHO neurosis screening schedule is the best in both sensitivity and specificity of validity, but its practice is time-consuming and laborious, which limits its application. SCL-90 and CMI (M-R) are imperfect in sensitivity of validity, and they cannot screen out the mental disorder in more than a half of the subjects. In a group test, they can hardly serve as a screening tool. UPI can screen out most of the mental disorder, and its sensitivity of validity reaches 83.1%. Additionally, the UPI questionnaire contains fake-test items, which could retest those who were missed due to untruly or not conscientiously answer the questionnaires. An acceptable way to obtain a true screening test is to give the individuals a propaganda of mental health and explain the questionnaires for 30 minutes before the test, which helps the examinee to understand the procedure and accept the questionnaires, so that the results of the test could be more reliable. In conclusion, UPI is a valuable screening tool to be recommended.
