OBJECTIVE: To observe the change of auditory brainstem response (ABR) in hearing deprivation rat model induced by bilateral cochlears ablation at different time points. METHOD: Forty SD rats were randomly divided into four experiment groups including 2-week group, 4-week group, 6-week group, 8-week group and four control groups with 5 rats (n = 10) in each group. Then bilateral cochlears ablation was applied to experiment groups. The threshold value of ABR was measured at different time and latent period of each wave was compared. RESULT: The threshold of ABR in experiment group was elevated significantly. The latent period of each wave was pro longed significantly (P < 0.01). In experiment group, the threshold value of ABR in 2-week and 4-week group was significantly greater than that in 6-week group and 8-week group (P < 0.01). CONCLUSION Bilateral cochlears ablation surgery could elevate the threshold of ABR and latent period of each wave prolonged. The effect of hearing deprivation became apparent after surgery for 4 weeks.

Objective: To understand AIDS knowledge of the college students,to provide scientific evidence for making out the strategy of health education and synthetic prevention measure purposely.Methods An anonymous questionnaire was conducted with face to face interview to investigate the college students in Xi'an, and the software Epi info 5.0 was used to perform the statistical analysis of the data. Results 70.5% of university students knew the whole name of AIDS. As to three ways of HIV transmission, the investigation shows that 49.1% of college students knew three main ways. The 26.5% of college students mistakenly think that mosquito could transmit HIV. In general, the old, the married the literate, and medical students get more knowledge about AIDS than the young,the unmarried,the illiterate, and other major students. Conclusion The college students who are one of the most dangerous groups infected AIDS have poor knowledge. The situation of poor AIDS knowledge is extremely unfit to the prevalent tendency of AIDS, which our country is being faced. We suggest that the college students should be educated intensively on the health knowledge of AIDS especiallis beingy for freshmen.

Objective To prepare 5-aminolevulinic acid (ALA) and hematoporphyrin monomethyl ether (HMME) hydrogel suppositories and to evaluate their photosensitizer transfer efficiencies in rectal tumor tissue.Methods The BALB/c mice implanted SW837 rectal cancer cells subcutaneously were randomly divided into four groups:intrarectal suppository administration group,cutaneous administration group,intratumoral injection group and intravenous injection group.Fluorescence spectrophotometry was used to measure the concentration of protoporphyrin Ⅸ (PpⅨ) and HMME in rectal wall,skin and tumor tissue.The distribution of photosensitizer was determined by a fluorescence spectroscopy system.Results The concentration of PpⅨ in the ALA suppository administration group was 9.76 times (1 h) and 5.80 times (3 h) higher than that in the cutaneous administration group,and the differences were statistically significant (all P＜0.05).The maximal penetration depth of ALA in tumor tissue was about 3-6 mm at 2 h after the cutaneous administration.After the HMME suppository administration,the concentration of HMME in the rectal wall was very low.The maximal penetration depth of HMME in tumor tissue was less than 2 mm after the cutaneous administration.Conclusions ALA is more likely to penetrate mucosal barrier compared to skin tissue.The hydrogel suppository based rectal administration is expected to be a new administration method for the rectal cancer photodynamic therapy using ALA.

Objective To investigate the effects of ABO blood group factors on erythrocyte suspension ( RCS) transfusion reactions in patients. Methods TestⅠA total of 12 600 patients in whom RCS was transfused during operation at the department of anesthesiology of 11 hospitals of Inner Mongolia from January 2006 to January 2014 were selected. The occurrence of transfusion reactions ( fever [ an increase in body temperature>1 ℃ than that before transfusion] , allergy, hemolysis) was recorded in the patients. Test Ⅱ A total of 120 RCS?transfused patients of both sexes, aged 18-55 yr, weighing 45-75 kg, of American Society of Anesthesiologists physical statusⅠ or Ⅱ, who underwent surgical operation, were divided into 4 groups ( n=30 each) according to the blood group: blood group A group ( group A) , blood group B group ( group B ) , blood group O group ( group O ) and blood group AB group ( group AB) . The standard for RCS transfusion was defined as hemoglobin ( Hb) <7 g∕L, and Hb was maintained>10 g∕L. Before induction of anesthesia ( T1 ) , before blood transfusion ( T2 ) , and at 5 min, and 1, 6 and 24 h after blood transfusion ( T3?6 ) , blood samples were collected from the central vein for determination of the plasma tumor necrosis factor?alpha ( TNF?α) , interleukin?4 ( IL?4 ) and IL?10 concentrations by enzyme?linked immunosorbent assay. Results Among the 12 600 RCS?transfused patients, 216 cases developed transfusion reactions, and the incidence of transfusion reactions was 1.714%. For the patients of different blood groups, the incidence of transfusion reactions from the high to the low was blood group B, blood group AB, blood group A, and blood group O in turn ( P<0. 05 or 0.01) . Compared with group B, the plasma TNF?α and IL?10 concentrations were significantly decreased, and the plasma IL?4 concentrations were increased at T3?T6 in the other three groups ( P<0.05) . Compared with group AB, the plasma TNF?α and IL?10 concentrations were significantly decreased, and the plasma IL?4 concentrations were increased at T3?T6 in A and O groups (P<0.05). Compared with group O, the plasma TNF?α and IL?10 concentrations were significantly decreased, and the plasma IL?4 concentrations were increased at T3?T6 in group A ( P<0. 05 ) . Conclusion ABO blood group factors affect RCS transfusion reactions in the patients, and the incidence of transfusion reactions from the high to the low is blood group B, blood group AB, blood group A, and blood group O in turn.

Objective To explore the role and relationship of N-terminal pro-brain natriuretic peptide (NT-proBNP) and matrix metalloproteinase-9 (MMP-9 ) in risk stratification and prognosis assessment of non-ST elevation acute coronary syndrome (NSTE-ACS).Methods We recruited 114 patients with NSTE-ACS and classified them into three groups according to the GRACE risk stratification:high-risk,intermediate-risk and low-risk groups.Another 5 8 patients were recruited as controls.Arterial blood was collected before angiography for the measurement of serum NT-proBNP and MMP-9 .Gensini score was used to evaluate the degree of coronary artery stenosis.All the patients were followed up for 6 months and MACE was observed and recorded.Results ① The levels of lg NT-proBNP and MMP-9 significantly differed between the groups (P<0.05).② ROC curve analysis showed that lg NT-proBNP could predict MACE of NSTE-ACS;area under the curve was 0.795,the cutoff value was 2 .0 6 9 ,corresponding to the NT-proBNP value of 1 1 6 .5 6 ng/L.MMP-9 could predict MACE of NSTE-ACS;area under the curve was 0 .6 9 6 ,the cutoff value was 3 2 .4 9 ng/ml;both of the abnormal indexes could predict MACE with the sensitivity of 80.41%,specificity of 82.19%,and Youden’s index of 0.63.③ Cox regression analysis showed that abnormal MMP-9 and NT-proBNP levels were independently related to the incidence of MACE by the value of OR as 3.751.Conclusion MMP-9 and NT-proBNP may be used as serological indicators in risk stratification of NSTE-ACS. The combined use of NT-proBNP and MMP-9 increases the power of predicting MACE.
