OBJECTIVE:To study the effect and its mechanism of dexmedetomidine(Dex)on inflammatory response in septic mice. METHODS:Mice were randomly divided into normal control group,model group,miR-146a inhibitor (50 mg/kg)+Dex (50 μg/kg)group,Dex low-dose,medium-dose,high-dose groups(10,30,50 μg/kg),10 in each group. Except for normal con-trol group,other groups were intraperitoneally injected lipopolysaccharide to induce septic models,intraperitoneally injected rele-vant medicines after 0.5 h. After drug intervention for 6 h,miR-146a expression,IRAK1 and TRAF6 mRNA expressions in periph-eral blood mononuclear cells in each group were detected by real-time fluorescence quantitative polymerase chain reaction method. IRAK1,TRAF6 protein expressions in peripheral blood mononuclear cells in each group were detected by Western blot method. TNF-α,IL-6 levels in serum were detected by enzyme-linked immunosorbent method. RESULTS:Compared with normal control group,miR-146a expression,TNF-α and IL-6 levels,IRAK1,TRAF6 mRNA and protein expressions in peripheral blood mononu-clear cells in model group were increased(P<0.01). Compared with model group,miR-146a expression in peripheral blood mono-nuclear cells in Dex medium-dose,high-dose groups were increased;TNF-α and IL-6 levels,IRAK1,TRAF6 protein expressions were decreased (P<0.05 or P<0.01);while IRAK1,TRAF6 mRNA expressions changed less obviously (P>0.05). Compared with Dex high-dose group,miR-146a expression,in peripheral blood mononuclear cells in miR-146a inhibitor+Dex group was de-creased;TNF-α and IL-6 levels,IRAK1,TRAF6 protein expressions were increased (P<0.05 or P<0.01);while IRAK1, TRAF6 mRNA expressions changed less obviously(P>0.05). CONCLUSIONS:Dex can inhibit the inflammatory response in sep-tic mice. The mechanism may associate with inducing miR-146a expression and inhibiting the 2 important adaptor proteins IRAK1, TRAF6 expressions in Toll-like receptor 4/nuclear factor-κB pathway.

Community Health Service ( CHS) not only contains the treatment, but also considers the care as its responsibility. Therefore, its character of humanity service can be showed in the practice. However, besides the humanity, CHS needs some reasonable forms such as laws, systems as well, to protect its development and community habitants health. The author thinks that when the humanity and reasonableness conjunct on the solution and prevention for the medical tangle which occurs in the CHS, maybe the medical Ttreatment will come back to its birthday on which it ensured "care and console" as its duty, and it also can decrease the medical danger at length, then serve for the society and benefit for the people.

Objective To investigate the influence of coix seed triglyceride combined with transcatheter arterial chemoembolization (TACE) therapy on AFP, CD4﹢CD25﹢regulatory T (Treg) cells and cellular immune function in patients with advanced primary hepatocellular carcinoma (HCC). Methods A total of 50 patients with inoperable HCC, whose imaging examination showed no distant metastasis, were divided into the study group (n=25) and the control group (n=25). Coix seed triglyceride together with TACE was employed for the patients of the study group, while only TACE was adopted for the patients of the control group. For the patients of the study group, transcatheter hepatic artery infusion of 100 ml coix seed triglyceride was carried out during the performance of TACE, and postoperative intravenous drip of coix seed triglyceride (200 ml/d) was used for 5 days. The peripheral blood samples were collected one week before and one month after the treatment to detect the changes of AFP and T lymphocyte subsets (CD3﹢, CD4﹢, CD8﹢,CD4﹢/CD8﹢ and Treg) levels. One month after the treatment, enhanced CT, MRI or PET-CT was performed to evaluate the necrosis degree of the tumor. Results After the treatment, AFP levels was decreased in both groups, when compared the preoperative data the differences were statistically significant (P<0.01); the tumor necrosis rate of the study group was (57.7 ±8.2)%, which was slightly higher than (57.7±8.2)% of the control group, however, the difference was not statistically significant (P>0.05). In the study group, the percentage of Treg cells decreased from preoperative (8.27±6.65)%to postoperative (4.22± 1.59)%, the difference was statistically significant (P<0.01). The percentages of CD3﹢ and CD4﹢ and the ratio of CD4﹢/CD8﹢ increased from preoperative (55.78 ±13.66)%, (43.98 ±14.00)% and 1.22 ±0.64 to postoperative (62.29±10.78)%(P<0.01),(51.82±16.32)% (P<0.05) and 1.54±0.80 (P<0.05) respectively, while the percentage of CD8﹢decreased from preoperative (45.71±12.94)%to postoperative (39.70±12.41)%(P<0.05). In the control group, no statistically significant differences in the above mentioned indexes existed between preoperative data and postoperative ones (P>0.05). Conclusion In treating advanced primary HCC, coix seed triglyceride combined with TACE can reduce the percentage of Treg cells, thus, influence the patient’s cellular immune status and possibly decrease the recurrence rate of HCC after TACE therapy.

Her-2 receptor has already been identified as one of the most important biological markers of some malignant tumors,and also plays an important role in the biological behavior of those tumor cells.The over-expression of Her-2 receptor is associated with radioresistance of various tumor cells,and thus an antibody to Her-2/neu receptor can probably function as a radiosensitizer.In this review,we summarized some advances in the molecular mechanism and clinical aspects of the relationship between Her-2 and cellular radiosensitivity.

BACKGROUND: Excessive nitric oxide (NO) release can cause the occurrence and development of brain injury and senile dementia due to the apoptosis induction role of NO at high concentration to nerve cells. Therefore one strategy to prevent and treat senile dementia is inhibiting the apoptosis induced by NO.OBJECTIVE: To observe whether acidic peptide will inhibit the neuron apoptosis caused by NO. DESIGN: An cell and molecule observation experiment by comparisons. SETTING: Department of Biochemistry and Molecular Biology of Basic Medical College in Zhengzhou University and the Second Laboratory of Biological Active Peptide Institute in Zhengzhou University. MATERTALS: The experiment was performed between May 2003 and May 2005, in the Second Laboratory of Biological Active Peptide Institute in Zhengzhou University and the cell culture room of Department of Biochemistry and Molecular Biology of Basic Medical College in Zhengzhou University. The newborn SD male rats within 24 hours after birth were provided by the Animal Center of Henan Province (410117).METHODS: On day 11 of primary cultures, hippocampus neurons of the newborn SD rats were pretreated with different dosages of acidic peptide for six hours. Sodium nitroprusside (SNP) of 50 μmol/L final concentration was added to the cells which were incubated for another 24 hours. Cells were collected and adopted in this experiment of five different groups, namely normal control group, group treated with SNP, group of SNP plus 0.037 5 mg/mL acidic peptide, group of SNP plus 0.075 mg/mL acidic peptide, group of SNP plus 0.15 mg/mL acidic peptide. The cell's survival rate wasmeasure by methyl thiazolyl (MTT) method; The neurofilament protein was stained with the method of immunohisto chemistry. The shape of apoptosis was display with acridine orange fluorescent stain. Then DNA ladder zone of apoptosis cells was analyzed with the method of agarose gel electrophoresis. Western Blot and absorbance scan were used to determine the expression level of Bcl-2 protein and Bax protein.MAIN OUTCOME MEASURES: ①Experimental result of cell survival rate with MTT method;②Observation results of nuclear type of apoptosis; ③DNA electrophoresis analysis of apoptosis; ④Western Blot analysis results of Bcl-2 protein and Bax protein.RESULTS: ①Neuron survival rate was 58.9％ for group treated with SNP, 70.0％ for group of SNP plus 0.037 mg/mL acidic peptide, 72.8％ for group of SNP plus 0.075 mg/mL acidic peptide, and 75.3％ for group of SNP plus 0.15 mg/mL acidic peptide. ②Observation results of nuclear type of apoptosis: Significant characteristics of apoptosis were seen in group treated with SNP. The nucleus of hippocampus neuron treated with different concentrations of acidic peptide plus SNP was similar to that of normal control group in morphology. ③The results of DNA electrophoresis analysis of apoptosis: Only the neuron DNA of group treated with SNP showed clear characteristic DNA ladder zone of apoptosis on agarose gel electrophoresis. ④Analysis results of Bcl-2 protein and Bax protein with Western Blot and absorbance scan: The expression level of Bcl-2 protein in SNP treated group was decreased while that of Bcl-2 protein was increased. Bcl2 protein levels in acidic peptide plus SNP group were increased and Bax protein levels were decreased gradually with the increasing concentrations of acidic peptide compared with SNP treated group. CONCLUSION: Acidic peptide can inhibit neuron apoptosis, increase expression level of neuron Bcl-2 protein and decrease expression level of neuron Bax protein.

Objective To investigate the alleviative effects of lidocaine postconditioning on pulmonary injury following ischemia reperfusion.Methods Seventy-two adult SD rats were randomized to 4 groups:sham group,ischemia-reperfusion(I-R) group,ischemic postconditioning(IPC) group and lidocaine postconditioning group. The pulmonary ischemia-reperfusion model was established by occlusion of the left hilum of lung for 45 min and the reperfusion was taken by removing the clamp for 2 h. At the moment of reperfusion,lidocaine 4 mg/kg was injected as a priming dose following a continuous rate of 4 mg/(kg?h). PaO2,TNF-?,W/D of left lung,the level of MDA of left lung tissue were measured. At the end of reperfusion left lung was removed for microscopy. Results After reperfusion PaO2 of lidocaine group was much higher than that of I-R group(P

Objective To assess the radiological imaging findings of hepatic inflammatory myofibroblastic tumor and to discuss the appropriate morphological classification.Methods A total of 22 patients with hepatic inflammatory myofibroblastic tumor confirmed by pathology were enrolled.Imaging performance of hepatic inflammatory myofibroblastic tumor were analyzed and the lesions were classified into appropriate type based on the imaging findings.Results Totally 23 lesions were found in 22 patients.The typical imaging features included great enhancement at later phase (13/20),moth eat en central necrosis (12/23) and peripheral shell (12/23).Seed in fruit was the most typical classification (8/23),followed by Seedless fruit (7/23).Conclusion Hepatic inflammatory myofibroblastic tumur typically shows as a single nodular lesion with moth eaten necrosis and peripheral shell like a Seed in fruit.The enhancement at later phase (especially the peripheral enhancement) can be regarded as a particular feature.
