Objective To observe the effects of T-lymphocyte function subsets,IL-4 and IFN-γ cell factor in different dose and stage after irradiation.Methoda The C57BL/6j mice were divided into shammed irradiation group and model groups.The radiation hurt model was induced by 60Co gamma rays(0.7,1.4,2.8 and 5.6 Gy).The changes of T-lymphocyte subsets CD3,CD4,CD8,IL-4 and IFN-γ in spleen cells were analyzed by flow cytometry in acute injury stage and recovery stage after irradiation.Results The lymphocyte subsets CD3 +,CD4+ and CD8 + decreased after irradiation,which were related to the irradiation dose.At 1 day after irradiation,the decreasing level of IFN-γ was higher than that of IL-4.When irradiation dose was over 2.8 Gy,IL-4 / IFN-γ showed a markedly increased compared with control group.At 25 days after irradiation,CD3 +,CD4+,CD8 +,CD4 +/CD8 +,IL-4 and IFN-γ recovered obviously,but they did not recover to the normal level of shammed irradiation group.Conclusions The depression of mouse immune function induced by γ-irradiation might be caused by changes of CD3,CD4,CD8 and CD4/CD8 ratio,especially the imbalance of IL4 and IFN-γ.

Objective To compare the changes in nitric oxide (NO), total ability of anti-oxidize antioxidase, superoxide dismutase (SOD), glutathion peroxidase (GSH-PX), catalase (CAT) and maleic dialdehyde(MDA) in rats after single and accumulative 60Co γ-irradiation . Methods 48 rats were randomly divided into two groups of single and accumulative irradiation. Each group was irradiated by 60Co gamma-rays. The total irradiation doses were 0.4, 0.8, 1.6, 3.2 and 6.4 Gy, respectively in each group. The NO, total ability of anti-oxidize antioxidaze, SOD, GSH-PX, CAT and MDA in serum were measured at day 1 after last irradiation. Results Compared with the single irradiation group, the NO (52.6-117.9 μmol/ml), total ability of anti-oxidize antioxidaze (3.3-26.2 U/ml), the antioxidase activity of the SOD (26.3-167.5 U/ml), GSH-PX (740.8-2462.4 U/ml), CAT (3.3-29.4 U/ml) and the content of MDA(29.3-155.1 nmol/ml) of mt serum in accumulative irradiation group were increased after irradiation, which was related with the accumulative irradiation dose. For instance, total ability of anti-oxidize antioxidase (26.2 U/ml), antioxidase activity of the SOD (167.5 U/ml) and CAT (29.4 U/ml) in 0.4 Gy group of accumulative irradiation were significandy increased when compared with those of control group. However, the content of MDA in accumulative irradiation group was obviously higher than that in single radiation group when the irradiation doses delivered over 3.2 Gy, which might be correlated with higher antioxidase activity. Conclusions Low dose of accumulative gamma-rays irradiation can induce the stimulative effect of antioxidase activity. However, higher dose of accumulative gamma-rays irradiation can damage the activity of antioxidase.

Objective To study the effects of bioartificial kidney(BAK)treatment on cytokines interleukin-10(IL-10)and tumor necrosis factor-α(TNF-α),biochemistry indexes,and survival time in acute uremic pigs with multiple organ dysfunction syndrome(MODS).Method Pigs with MODS and acute renal failure(ARF)were treated with BAK(group A,n = 6)or sham BAK containing no cells(group B,n = 6)or received no treatment(group C,n = 5).Data on blood pressure,hepatic and renal functions,serum IL-10 and TNF-α levels,arterial blood gas and survival time of all the pigs were recorded.Comparisons of values were done using Student's t-test or repeated-measures analysis of variance(ANOVA).ResultsMean arterial pressure(MAP,mmHg)responsed more rapidly and reached higher values in group A (91.82±5.73)compared with group B and C at 24 hours(P＜0.01).The peak level of serum EL-10(pg/mL)ingroupA(249.57±43.51)was significantly higher than that in group B and C(132.06± 17.53,104.25 ±13.42,P＜0.01).Serum TNF-a level(pg/mL)in group A dropped gradually to(402.91 ± 32.47)at 24 hours,and had significant discrepancy compared with that before the treatment(537.16 ± 38.45)and that in groupB(P＜0.05).The average survival time(hours)in group A(113.01 ± 14.32)was significantly longer than that in the group B and C(P＜0.01),which was prolonged by 35.93%and 63.90%,respectively.ConclusionsTreatment with BAK can prolong the survival time of uremic pigs with MODS,possibly through ameliorating the MAP,increasing the level of IL-10 and reducing the concentration of TNF-α.

Objective To investigate the correlation of anthropometric parameters with alanine aminotransferase (ALT) in Qinhuangdao college students.Methods A total of 789 subjects from two colleges in Qinhuangdao City (369 men and 420 women) were recruited using a cluster-stratified sampling method.Anthropometric measurements included height,body weight,waist circumference,hip circumference,blood pressure.and ALT.Body mass index,waist to height ratio,and waist to hip ratio were calculated.Results Elevated ALT was found in 16.3% of male participants and 4.0% of females(P<0.05).For males,those with elevated ALT showed significantly higher levels of anthropometric parameters (P<0.05).In females,the levels of anthropometric parameters were similar between subjects with or without elevated ALT(P>0.05).Receiver operating characteristie curve analysis also showed that obesity indices predicted elevated ALT only in men [area under the curve:0.8-0.9(P<0.05) in men,0.5-0.6(P>0.05) in wonlen].Blood pressure did not predict elevated ALT in both men and women (area under the curve:0.5-0.7).Conclusion Dender difference of obesity indices could be found in Qinhuangdao college students.Obesity indices may be independent predictors of elevated ALT in men.However,blood pressure seems not to be an independent predictor of elevated ALT.

Objective To investigate the correlation between carotid intima-media thickness (CIMT) and glucose fluctuation in patients with type 2 diabetes mellitus (T2DM).Methods Sixty-eight T2DM patients admitted to Beijing Military General Hospital from March to August 2012 were enrolled in the study,including 32 cases with CIMT thickening (CIMT ≥ 0.9 mm) and 32 cases with normal CIMT (CIMT ＜0.9 mm).The 72 h continuous blood glucose levels were monitored from the day of admission.Results There were no significant differences in the gender,age,body mass index (BMI),systolic and diastolic blood pressure,HDL-C,LDL-C,CHO,TG,glycosylate hemoglobin (HbA1c),fasting blood glucose(FBG) and postprandial average blood glucose (MPBG) between two groups (P ＞ 0.05).The atherosclerosis (AS) score and mean amplitude of glycemic excursion (MAGE),glucose standard deviation,frequency of glycemic excursion (FGE) and absolute mean of daily differences (MODD) in patients with thickening CIMT were (11 ± 7) years,(6.9 ± 3.0) mmol/L,(2.8 ± 1.2) mmol/L,(3.4 ± 1.5) times/d,(2.8 ± 1.3) mmol/L,(4.5 ± 1.0) score,respectively ; while those in patients with normal CIMT were (8 ±6) years,(4.2 ± 1.1) mmol/L,(1.6 ± 0.5) mmol/L,(2.2 ± 0.8) times/d,(2.0 ± 1.0) mmol/L,(3.3 ±0.6) score,respectively.There were significant differences between two groups (all P ＜ 0.05).Pearson correlation showed that CIMT was positively correlated with MAGE,FGE,MODD,course of disease,diastolic blood pressure,LDL-C,MPBG and AS score (P ＜ 0.05).Multiple stepwise regression analysis showed that MAGE,MBPG were the influencing factors of CIMT.Conclusions The CIMT of patients with T2DM is closely correlated with glucose fluctuation,indicating that reduction of blood glucose fluctuation and MAGE,MPBG levels may delay the occurrence of diabetic macroangiopathy.

AIM: To investigate the relations between the proliferation and phenotype change of adventitial cells and the expression of T GF-?1 in adventitia after arterial injury. METHODS: After abdominal artery injury in rabbits, adventitial cel l proliferation and phenotype were identified by immunohistochemistry, transmissi on electron microscope and in situ Hybridization. RESULTS: Three days and 7 days after injury, the PCNA-positive ce lls were significantly increased. The previously weakly actin-positive adventiti al cells became strong-actin staining, the typical myofibroblast featurses of ad ventitial cells were detected by TEM 7 and 14 days after injury. Three days afte r vascular injury, there was a marked increase in the nu mber of cells that demonstrated the presence of TGF-?1 transcripts within the adventitia. Seven days after arterial injury, adventitial cells continued to ex press TGF-?1. on day 28, the number of TGF-?1-expressing cells was markedly r e duced in the adventitia. CONCLUSION: This study demonstrates that the proliferation and p henotype modulation of adventitial cells are associated with induction of TGF- ?1 expression in adventitia after arterial injury.
