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.

Objective To investigate the impact of chemotherapy plus fluoxetine on depression and quality of life of tumor patients.Methods 160 cases cancer patients were randomly divided into the control group and the experimental group with 80 cases in each group.The control group received routine chemotherapy,while the experimental group adopted fluoxetine based on routine chemotherapy.The incidence of depression and improvement of life quality were compared between two groups.Results The incidence of depression was lower,and proportion of patients with good quality of life was higher in the experimental group compared with those of the control group.Conclusions To take chemotherapy plus fluoxetine has certain values in decrease depression and improve quality of life.

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.

Purpose:To compare with the efficacy in the immediate effects and toxicities on patients with advanced gastric cancer treated with 5-fluorouracil (5-FU) and leucovorin (LV) combined with oxaliplatin or paclitaxel. Methods:Forty patients with advanced gastric cancer, whose metastases to organs or sites included liver, lymphy node, abdominal cavity, abdominal wall, etc, were enrolled in this study, and was randomly divided into two groups (A and B groups). The A group of 20 patients (70% of them were retreated patients) were treated with a combination of oxaliplatin, leucovorin(LV) and 5-fluorouracil(5-FU) continuous infusion regimen. The B group of 20 patients (55% of them were retreated patients) were treated with a combination of paclitaxel, leucovorin (LV) and 5-fluorouracil(5-FU) continuous infusion regimen. Results:Of the 40 evaluable patients, there were two complete responses and seven partial responses (response rate 45%) in the A group, and nine partial responses (response rate 45%) in the B group. All patients were evaluable for toxicities. The most common toxicities were bone marrow depression,peripheral neuropathy,digestive tract toxicities and liver function damage in the A group. The most common toxicities were bone marrow depression and liver function damage in the B group. Conclusions:These two regimens (5-fluorouracil and lcucovorin combined with oxaliplatin or paclitaxel) showed good efficacy and acceptable toxicities in advanced gastric cancer patients, and the 5-fluorouracil and leucovorin combined with oxaliplatin regimen may have some virtues, such as economics, convenience of medication and less serious toxicities.[

Homogenous fat extract was injected through the femoral vein to induce respiratory distress syndrome in 15 dogs. It was found that the changes of blood gases, chest x-ray films, and lung pathology of the dogs were similar to those of adult respiratory distress syndrome.The pathogenesis was extensive pulmonary fat embolism with complement activation and free radicals formation. Vitamin E was consumed during antiperoxidation. It is believed that this model serves better for the study of respiratory distress syndrome.

The therapeutic effects of prostaglandin E1 on respiratory distress syndrome induced with homogeneous fat extraction were observed in dogs.It was found that prostaglandin E1 could alleviate hypoxemia,reduce pulmonary capillary permeability,and attenuste pulmonary edema.The mechanism of the therapeutic efficiency of prostaglandin E1 on pulmonary damages is that prostaglandin E1 can inhibit the adherence of polymorphonuclear netttrophils and the genesis of oxygen free radicals,and protect the pneumocyte type Ⅱ.

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.

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.

OBJECTIVE:To observe the efficacy and safety of Bifid triple viable capsule in the treatment of ulcerative colitis (UC). METHODS:94 patients with UC were randomly divided into control group and research group. Control groups was given nutrition support,light diet and 5-amino salicylic acid and other conventional treatment;research group was additionally given 420 mg Bifid triple viable capsule,3 times aday. Treatment course for both group was 8 weeks. The clinical efficacy,and serum D-lac-tic acid,diamine oxidase(DAO)levels before and after treatment,and incidence of adverse reactions in 2 groups were observed. RESULTS:The total effective rate in research group was significantly higher than control group,the difference was statistically sig-nificant(P<0.05);after treatment,serum D-lactic acid,DAO levels in 2 groups were significantly lower than before,and re-search group was lower than control group,the differences were statistically significant(P<0.05 or P<0.01);and there was no sig-nificant difference in the incidence of adverse reactions(P>0.05). CONCLUSIONS:Based on the conventional treatment,both the efficacy and safety of Bifid triple viable capsule are good in the treatment of UC.
