ABSTRACT
OBJECTIVE: To explore the changes of the serum immune cytokines in medical radiation workers exposure to low dose ionizing radiation. METHODS: Totally 244 medical professionals working with radiation(61 diagnosis radiology,51 nuclear medicine,74 radio therapeutics and 58 interventional radiology) from 7 hospitals of Guangdong Province were selected as study subjects by using the typical sampling method; 51 administration workers who did not expose to radiation were selected as control group. The radiation dose of these individuals was monitored by thermoluminescent measurement instrument for one year. Venous blood was collected and the levels of interferon γ(IFN-γ),interleukin 10(IL-10),transforming growth factor-β1(TGF-β1) in serum were examined by enzyme-linked immuno sorbent assay. RESULTS: The maximum annual average dose of radiation per person of the medical radiation workers was 0. 41 mSv/a. It was smaller than the occupational exposure limit(20. 00 mSv/a). The annual average dose of radiation per person in the group of nuclear medicine was significantly higher than those of diagnosis radiology,radio therapeutics and interventional radiology(P <0. 01). Among the male staffs,the expression of IL-10 in the diagnosis radiology group,radio therapeutics group and interventional radiology group was lower than that in the control group(P < 0. 05); the expression of IL-10 in radio therapeutics group was lower than those in nuclear medicine group and interventional radiology group(P < 0. 05); the ratio of IFN-γ/IL-10 in radio therapeutics group was higher than those in diagnosis radiology group,nuclear medicine group,interventional radiology group and control group(P < 0. 05). These individuals were divided into 3 different dose group(0. 03-,0. 06-and > 0. 15 m Sv/a) based on their average radiation dose. The expression of IL-10 in male staffs of these3 dose groups was lower than that of the male control group(P < 0. 05). CONCLUSION: Long-term low dose ionizing radiation may restrain the expression level of IL-10 in the male staffs.
ABSTRACT
Objective To observe the effects of dexmedetomidine on the perioperative stress response and immunologic function in hepatectomy patients with hepatitis cirrhosis.Methods Forty patients(Child-Pugh A or B),ASA Ⅱ or Ⅲ with hepatitis cirrhosis undergoing hepatectomy were randomly divided into dexmedetomidine group(group D)and control group(group C)with 20 cases in each.Patients in group D were administered 0.5 μg/kg bolus dose of dexmedetomidine over 10 min, followed by 0.4 μg·kg-1 ·h-1 infusion until closing abdomen.And patients in group C were given normal saline by the same way as in group D.Flow cytometry was used to detect peripheral blood T lymphocytes (CD3 + ,CD4 + ,CD8 + ,CD4 +/CD8 + ),NK cells at 30 min before anesthesia(T0 ),imme-diately(T1 ),24 h(T2 )and 48 h(T3 )after surgery.Enzyme-linked immunosorbent assay was used to detect the levels of inflammatory cytokines concentration(IL-2,IL-10)at T0-T3 and stress hormones (Cor,ACTH,ALD)at T0 ,T2 and T3 .The levels of SBP,DBP and CVP at T0 ,immediately with intu-bation(Ta ),T1 and extubation(Tb ).Results Compared to those at T0 ,the levels of CD3 + ,CD4 + , CD8 + ,CD4 +/CD8 + at T1 and T2 were significantly lower in both groups(P <0.05),and the levels in group D were obviously higher than those in group C(P <0.05).The levels in group D were back to preoperative levels at T3 ,but the levels in group C were still lower than those at T0 (P <0.05).The levels of NK cells were higher at T1 in both groups,and the levels in group D was significantly higher than those in group C(P <0.05).Compared to those at group D,the concentration of IL-2 was lower at T1 and T2 ,the concentration of IL-10 was higher at T2 and T3 in group C (P <0.05).The levels of Cor,ALD,ACTH at T2 and T3 were significantly higher than those at T0 in both groups,but those in group D were markedly lower than those in group C (P < 0.05 ).The SBP,DBP and CVP of two groups was no statistically significant difference at T0 ,and SBP,DBP and CVP of the group D at Ta , T1 ,Tb was lower than that of T0 and group C (P <0.05).Conclusion Patients with hepatitis cirrho-sis underwent general anesthesia has certain immune suppression after liver cancer surgery,and con-tinuous intravenous infusion of dexmedetomidine during anesthesia may suppress the perioperative stress reaction effectively and alleviate the inhibition of immunologic function.
ABSTRACT
OBJECTIVE@#To discuss the effect of Glycyrrhiza uralensis (G. uralensis) Fisch polysaccharide on growth performance and immunologic function in mice in Ural City, Xinjiang and to provide important data supporting the application of Glycyrrhiza polysaccharide.@*METHODS@#A total of 100 Kunming mice aged 3 weeks old were randomly divided into 5 groups with 20 mice in each group (10 were females and 10 were males). About 0.5 mL normal saline was given to the mice of control group every day and 0.5 mL G. uralensis Fisch polysaccharide was given to the mice of other groups at the concentration of 1, 20, 50 and 100 mg/mL, respectively. The growth performance (average body weight, average daily feed intake and feed efficiency), immune organ indexes (spleen index and thymus index) and immunologic function (serum IL-2, CD4/CD8 and the activity of NK cells) of mice in each group were detected continuously.@*RESULTS@#The average body weight, feed efficiency, serum IL-2, CD4/CD8 and the activity of NK cells of mice were increased with the increase of administrated time after administrating G. uralensis Fisch polysaccharide and were reached up the largest level on Day 28. At the same time, each index was proportional to the given dose and was significantly higher than those of control group and reached up the largest level at the administrated dose of 100 mg/mL. After administrating G. uralensis Fisch polysaccharide, the spleen index and thymus index of mice were increased with the increase of administrated dose and the spleen index and thymus index of mice administrated with the dose of 100 mg/mL were maximum which was more than 1.51 times and 1.43 times of that in control group, respectively and the comparative differences showed statistical significance (P 0.05).@*CONCLUSIONS@#G. uralensis Fisch polysaccharide can significantly improve the growth performance and immunologic function of mice and laid a research basis for the clinical application of G. uralensis Fisch polysaccharide.
