Objective To evaluate the value of the four kinds of diagnostic method in acquired immune deficiency syndrome (AIDS) infection complicating tuberculosis (TB) .Methods 52 cases of human immunodeficiency virus (HIV) infection complica‐ting TB were taken as the observation group and 100 cases of TB without complicating HIV infection were taken as the control group .The two groups were performed the PPD test ,sputum Mycobacterium tuberculosis culture ,tuberculosis antibody and inter‐feron gamma release assay(IGRA) for conducting the diagnosis .Results The positive rate of the PPD test ,sputum Mycobacterium tuberculosis culture and tuberculosis antibody in the control group were significantly higher than those in the observation group ,the differences were statistically significant (P<0 .01);the positive rate of the IGRA in the observation group was obviously higher than that of the PPD test ,sputum Mycobacterium tuberculosis culture and tuberculosis antibody ,the differences had statistical sig‐nificance (P<0 .01) .The negative occurrence rate of the IGRA in the observation group treated by the antiretroviral therapy was obviously higher than the positive rate ,the difference was statistically significant (P<0 .05) .Conclusion The IGRA may be a sen‐sitive method for diagnosing HIV infection complicating TB and the antiretroviral therapy may have a certain impact on the results .

Objective In this study,we aim to investigate and evaluate the application of peer education on the teaching of medical graduate students and to evaluate the teaching effect,in order to provide the basis for subsequent practice reform.Methods 49 graduate students majoring Internal Medicine-Pulmonology were randomly divided into traditional teaching(24) and peer education groups (25).We chose the primary culture technology of rat distal pulmonary arterial smooth muscle cells to be the teaching contents.For the traditional teaching group,we used the mode of class lecture giving and experimental skills learning under the assistance of the teachers; while in the peer education group,students benefited from the combination of class lecture given by the teacher and the seniors fixed teaching in which seniors help younger students.We selected the experimental operating time,cell purity and the practicing time to reach a standard culture as the evaluation indexes by filling a follow up questionnaire.The SPSS 13.0 was applied to the related data forx2 or t test.Results In the traditional teaching group,the average time to reach three times of standard culture was(3.2 ± 0.5) hour,which was(2.3 ± 0.4) hour in the peer education group.The cell purity was 80.1 ± 3.6％ in the traditional teaching group,while(85.4 ± 5.9)％ in the peer education group.The average practicing time was(6.3 ± 1.0) in the traditional teaching group,while(4.9 ± 0.6) in the peer education group.The peer education group master the teaching content better than the traditional teaching group (P=0.00).95.8％(23/24)of the students in the peer-education group considered the teaching contents simple,which was statistically higher(P=0.00) than traditional group (62.5％,15/24).Meanwhile,95.8％ (23/24)of the students in the peer-education group considered the teaching methods easy to accept,which was also statistically higher(P=0.02) than traditional group(70.8％,17/24).The difference was statistically significant (P=0.02).Conclusion The application effect of peer education is good and there is high degree of acceptance among the students.Besides,peer education accords with the medical postgraduate experiment teaching rules,and can cultivate medical graduate students' spirit of cooperation and communication ability in the process of implementation.

Objective:To evaluate the effect of the occlusal surface height of a mandibular posterior implant-supported single crown on stress in bone tissues.Methods:Three-dimensional finite element models of the implant-supported single crown replacing the missing right lower second premolar,mesial and distal natural teeth,periodontal membrane,alveolar bone,loaded rigid body and analog food of almond were established.Using the Federation Dentaire International (FDI)system,the first premolar, the second premolar and the first molar were represented with 44,45,46.Three occlusal surface heights of the crown were studied:(1 )normal height;(2)1 5 μm reduction in height;(3)30 μm reduction in height.The models were loaded by independent loading with maximal occlusal force(44 by 280 N,45 by 360 N,and 46 by 480 N)and average occlusal force(44 by 1 40 N,45 by 1 80 N,and 46 by 240 N)on the single crown;combined loading (maximal occlusal force transformed into uniform load of 3 .7 MPa on top of rigid body,in contact with points on the occlusal surface),and analog almond-like food loading (average occlusal force transformed into uniform load of 1 .67 MPa in simulated food chewing,in contact with points on the occlusal surface).Results:For maximal biting force under independent loading,Von Mises stress peak values in bone tissues around 44,45,and 46 were 82.57 MPa,45.26 MPa and 27.79 MPa;For average biting force,peak values were 41 .28 MPa,22.63 MPa and 1 3.89 MPa.Under com-bined loading,compared with the normal occlusal surface height group,Von Mises stress peak values de-creased 4.6 MPa,by 0.84%;increased 7.52 MPa,by 20.04%,and decreased 1 .8 MPa,by 5.84%, for 45,46,and 44 in the 30 μm infra-occlusion group,respectively.Under food loading,Von Mises stress peak values decreased 0.34 MPa,by 1 .62%;increased 1 .1 1 MPa,by 2.66%;and increased 0.06 MPa,by 0.54%,and for 45,46,and 44 in the 30 μm infra-occlusion group,respectively.Con-clusion:Within the limitation of this study,within 30 μm reduction of the occlusal surface height of im-plant-supported single crown,no significant difference of the peak values was observed.

Orexin is a new neuropeptide related to diet intake and regulation of endocrine and metabolic functions. Rat model with insulin resistance (IR) was induced by high fructose diet and the extent of IR was assayed by hyperinsulinemic euglycemic clamp technique. The results showed that high fructose diet might induce IR and results in disturbance between orexin and leptin. Blood glucose, serum insulin, lipid metabolism and leptin may participate in the regulation of orexin.

Total hip arthroplasty (THA) is a vital therapeutic tool for hip terminal disease. Frequently, hidden blood loss exists in the postoperation, which seriously affect the postoperative rehabilitation of patients. It is urgent need to solve the problem that how to fundamentally prevent and reduce hidden blood loss after THA. Although THA has its own operational reason in blood loss, and also relates to a variety of risk factors, the mechanism of hidden blood loss is not clear. Tranexamic acid has a significant role in preventing perioperative blood loss, and the correlation of hidden blood loss and fibrinolytic mechanism would be confirm necessarily in the future,which will produce positive significance in completing the mechanism of hidden blood loss.
