The expression of C-myc, K-ras and H-ras oncoproteins in lymphocytesand monocytes, and NK subsets were studied in 21 patients with Behcet's syndrome (BS)and 40 healthy individuals. CD16~+,57~- cells of NK from BS patients were much decreasedwhen compared to the control. The positive percentages of three kinds of oncoprotein in BS lymphocytes and C-myc and K-ras oncoproteins in BS monocytes were significantly higher thanthat of the control. Positive correlations were found not only between C-myc expression oflymphocytes and serum ?-globulin%, IgM and IgG levels in BS, but also between C-mycexpression of monocytes and ESR. Expression of K-and H-ras oncoproteins in lympho-cytes and monocytes from BS patients were found to be negatively correlated with serumIgA level. Negative correlation was also found between C-myc expression in monocytesand CD16~+,57~- subset of NK. The significance of these results and the possible correlationsbetween BS and autoimmunity were discussed. It was suggeted that autoimmunity mightbe an important mechanism underlying BS.

Objective To explore if obesity is related to bronchial hyperresponsiveness in different sexuality.Methods A total of 1180 patients with provocation test positive were studied.We analysed the relation of body mass index(BMI)and FVC,FEV1,the relation of BMI and PC_20 FEV1 in all patients and in the men and the women,respectively.Results There was negative correlation between BMI and FVC,FEV_1 of the whole patients.There was also negative correlation between BMI and PC_20FEV_1 of the whole patients and the women but no correlation of the men.PC_20 FEV_1 of men was higher than that of women.Conclusion Obesity is related to the decrease of lung function and the increase of airway responsiveness,this affection is obviously in women.The airway responsiveness of women is higher than that of man.

Objective To study the therapeutic effect of diltiazem and felodipine in treatment of hypertension after renal transplantation.Methods Sixty patients with hypertension after renal transplantation who were treated with tacrolimus as basic immunosuppressive therapy were divided into two groups by random digits table method with 30 cases each.The diltiazem group took diltiazem 90 mg orally once a day.The felodipine group received felodipine 2.5 mg orally twice a day.The drug dosages were adjusted according to the level of blood pressure.The patients were followed up for 1 year.The artery pressure,concentration-to-dose ratio of tacrolimus and renal function was detected and compared.Results Blood pressure was significantly decreased in both groups after 1 year treatment.Blood pressure was found to be significantly lowered from (153.6± 7.5)/ (97.7 ±6.7) mm Hg (1 mm Hg=0.133 kPa) to (119.1 ± 26.4)/ (72.6± 19.3) mm Hgin felodipine group; and from (152.0 ± 7.6)/(95.4 ± 6.9) mm Hg to (120.3 ± 25.5)/(73.2 ± 22.5) mm Hg in diltiazem group.There was no significant difference in blood pressure before and after treatment between two groups (P ＞ 0.05).The concentration-to-dose ratio of tacrolimus was increased after treatment in diltiazem group[(173.2 ± 59.3) g/L vs.(119.3 ± 78.3) g/L] (P ＜ 0.05),but there was no significant difference before and after treatment in felodipine group (P ＞ 0.05).The serum creatinine had no significant difference in two groups (P ＞ 0.05).Conclusion Diltiazem and felodipine can be used safely and effectively in the treatment of hypertension after renal transplantation,and diltiazem can lower the dose of tacrolimus.

OBJECTIVE To investigate the tinnitus' prevalence in Healthy check-up population in Dalian City. METHODS 1748 cases (male 806, female 942) were chosen from the Physical Examination Center of our hospital from February 1st, 2015 to April 1st, 2015, the tinnitus questionnaire was performed. For the cases with the tinnitus symptoms, the characteristics of tinnitus were further inquired, including the course of tinnitus, seizure frequency, the duration of tinnitus, pulsatile or persistent, unilateral or bilateral. RESULTS The total prevalence of tinnitus is 32.4%(566/1748), the prevalence of persistent tinnitus is 18.3%(320/1748), and the transient tinnitus is 14.1%(246/1748); The prevalence of tinnitus in female are 36.4%(343/942), 20.0%(188/942) and 16.5%(155/942) in turn, which are higher than that of the male 27.7%(223/806), P<0.01; 16.4%(132/806), P =0.054, and 11.3%(91/806), P<0.01. Both the total and persistent tinnitus prevalence increase with age(P<0.01), but the transient tinnitus doesn't increase with age. The prevalence of objective and subjective tinnitus are 1.3%(6.9% out of total prevalence of tinnitus), and 17.0%(93.1% out of total prevalence of tinnitus), respectively. The rate of bilateral tinnitus is 78.1% out of total tinnitus, and rate of unilateral tinnitus is 21.9%(right 11.6%, left 10.3%). In addition, the rates of acute tinnitus, subacute tinnitus, and chronic tinnitus are 4.4%, 3.8%, and 91.9% out of total, respectively. Otherwise, the rates of sleep disorders and hearing loss complaining accounted for 31.9% and 14.1% respectively. CONCLUSION The prevalence of tinnitus is high in healthy check-up population of Dalian, the total prevalence of tinnitus is 32.4%, mainly bilateral,chronic and subjective.

Objective To explore the influence on isthmic spondylolisthesis (IS) from lumbar vertebras facet joint orientation (FJO) variation. Methods The lumbar vertebras of 60 patients scanned by 16-slices spiral CT were collected, 30 cases with IS was defined as isthmic group;30 cases with normal lumbar vertebras was defined as control group, the FJO at L3-4, L4-5 and L5-S1 were measured in two groups. The difference between two groups were compared at three levels, the difference between both sides of the facet joint orientation also was compared;the measured data and the data of 60 patients from foreign literature were compared at three levels. Results The FJO in isthmic group were (47.9±6.3)° ,(37.5±7.3)° , (37.9±7.7)° at the right of L3-4, L4-5, L5-S1 levels respectively,the FJO in control group were (53.1 ± 7.3)° , (40.5±6.3)° , (38.5±7.3)° respectively, the FJO in isthmic group were (48.1±6.0)° , (37.9 ± 7.4)° , (37.6 ± 7.6)° at the left of L3-4, L4-5, L5-S1 levels respectively, the FJO in control group were (52.3 ± 7.6)° , (41.6 ± 6.0)° , (38.2 ± 7.2)° respectively. The significant difference was found at L3-4 and L4-5 levels (P < 0.05), the orientation was similar at L5-S1 level (P > 0.05). The difference between the both sides FJO of lumbar vertebras was not found at L3-4,L4-5 and L5-S1 levels (P >0.05). The same as the measured data and the corresponding data from foreign literature(P > 0.05 ). Conclusions It seems possible that the coronal FJO may be the phenotypic representation of the familial etiology of IS. It is helpful for the measurement of lumbar vertebras FJO to find IS early,it is important to reduce and release the IS.

Objective To investigate the mechanisms of methylglyoxal(MG)-induced injury of hippocam-pal neurons. Methods Primary cultured of hippocampal neurons from 1-day-old Sprague-Dawley rats were incuba-ted with MG for different time and dose period. Cells proliferation were assayed by methyl thiazolyl tetrazolium (MTT),and apoptosis was quantified by flow cytometer using annexin V-FITC and propidium iodide (PI) stai-ning. The protein and mRNA levels of brain-derived neurotrophie factor (BDNF) and tyrosine kinase B(TrkB) were assayed with Western Blotting and real-time PCR. Results Treatment with MG resulted in a concentration-dependent (r=0.946, P < 0.01) and time-dependent (r=0.993, P < 0.01) decreasing neurons viability. Com-pared with Oh group(1. 633±0. 153)%, 100 μM MG treatment for 2h,6h, 12h and 24h,the cellular apeptosis rate were significantly increased ((2. 833±0. 153)%, (3. 367±0. 153)%, (4. 433±0. 404)% and (8. 833± 0. 306)% respectivdy,all P<0.01). MG also increased the BDNF mRNA and protein expression after 12h treat-ment (P<0.05 or P<0.01),but decreased the TrkB mRNA and protein expression in the cells after 6h treatment (P<0.05 or P < 0.01). Conclusion MG has direct toxic effect on hippocampal neurons and can impaire the BD-NF-TrkB signal pathway by inhibiting the expression of TrkB,and increasing the apoptosis of hippocampal neurons.
