AIM:Stress response induced by severe trauma can activate free radical, endothelial cell, and mononuclear macrophage to regulate the production and release of mediators of inflammation. In this study, we investigated the influence of semi-hepatectomy on cytokine in serum. METHODS:The experiment was performed at Clinical Laboratory of Datong Seventh People's Hospital from April to July 2006. The experimental procedure was accorded with animal ethical standards. Twenty-five healthy rabbits were selected and randomly divided into two groups. In hepatectomy group (n=20), semi-hepatectomy was performed by regular approach, following by abdominal closure when there was no active bleeding. In control group (n=5), only abdominal opening and closure was conducted. Peripheral venous blood was harvested 1 day before and 24 hours, 1, 2, 3, and 4 days after surgery (IGF) to examine the levels of cytokine in serum such as interleukin-2 (IL-2), IL-6, IL-8, tumor necrosis factor (TNF) and insulin-like growth factor by radioimmunity. RESULTS:Twenty-five rabbits were all included in final analysis. Compared with the control group, IL-2 increased 24 hours after surgery, and reduced even lower than preoperative level 1 week after surgery, but then increased gradually and approached to preoperative level 4 weeks after surgery. IL-6 and IL-8 were elevated within 24 hours after surgery, and reached the peak at 3 weeks, then began to reduce until the normal level 4 weeks after surgery. TNF decreased 24 hours after surgery, and then increased but decreased again 4 weeks after surgery. IGF increased 24 hours after surgery, reached the peak 2 weeks after surgery, and reduced to normal level 4 weeks after surgery. CONCLUSION:Hepatectomy can induce decrease in IL-2, T cell growth factor in peripheral blood, in rabbits.

OBJECTIVE:To observe the clinical efficacy Shuangyin suppository in the treatment of candidial vaginitis.METHODS:A total of 120 patients with candida albicans vaginitis were enrolled:60 were randomly assigned to receive Shuangyin suppository(trial group,1～2 pill qn.via vagina) for 10 days,another 60 to receive Baofukang suppository(control group,1～2 pill qn.to put in vagina) for 10 days.A total of 3 courses of treatment were conducted for both group(one course of treatment was conducted in each menstrual cycle).RESULTS:After 3 course treatment,54 cases(90%) were cured and 6(10%) showed excellent efficacy for the treatment group;however,45 cases(75%) were cured and 15 cases(25%) showed excellent efficacy for the control group.There were significant differences in the cure rates between the trial group and the control group(P

Exosomes are nanometer membranous vesicles which can be distributed in a variety of biological fluids,including peripheral blood,urine,saliva and so on.Currently,the multi-step differential centrifugation is a efficient method which can be used to isolate exosomes.Exosomes are released by all types of cells.Exosomes can carry proteins and RNAs from derived cells,involve in exchange of information between cells,and play an important role in physiological and pathological processes of immunoregulation and inflammatory responses.Age-related macular degeneration (AMD) is the leading indication of severe visual impairment in adults over 50 years old.The exact etiology of AMD is still unknown,and its pathogenesis may involve various factors.New studies showed that exosomes secreted by retinal pigment epithelium (RPE) cells may be associated with AMD.The elevated levels of protein in exosomes from RPE,such as αB-crystalline,are associated with druse in AMD.Stress-altered exosomes proteins were found involving in regulation of apoptosis and survival of RPE.RPE cells membrane complement regulators,CD46 and CD59,could contribute to lesion formation in the outer retina and Bruch's membrane during the development of AMD.Further,exosomes from RPE cells may be associated with the genesis of choroidal angiogenesis.There remain thorough studies to be conducted,which would reveal new approaches for the diagnosis and treatment of AMD in the future.

OBJECTIVETo observe the lower gastrointestinal mesenchymal tumors CT virtual endoscopy and pathology, and to explore its possible mechanism.

METHODSSelect 80 patients suspected colon gastroenterology treat in the hospital gastroenterology department, randomly divided into experimental group and control group, 40 cases in experimental group were given CT virtual endoscopy and pathological check, the control group received conventional colonoscopy and pathological check, and all the results compared with the pathological results.

RESULTSCompared with the pathological test results, consistent rate with the experimental group reached 94.73%, the same rate was 92.85% in control group. The difference was not statistically significant (P > 0.05).

CONCLUSIONSCT virtual endoscopy can quickly image and draw detailed information, and can improve the sensitivity and specificity of cancer diagnosis greatly. Clinically, CT virtual endoscopy have the same function as colonoscopy, can replace colonoscopy, can be important complement of electronic colonoscopy by those who cannot tolerate electronic colonoscopy or have contraindications. Its value is worth taking a step forward in-depth study.

Objective To explore the relationship between police' s occupational pressure and their job burnout and health. Methods 251 policemen completed the police occupational pressure questionnaire, Maslach Burnout Inventory-General Survey and general heath questionnaire. Results Occupational pressure was positively related to emotional exhaustion and cynicism( r = 0.365 ～ 0.472 ), and not related to diminished personal accomplishment( r = - 0.004 ). Occupational pressure had negative effect on mental health (β = - 0. 1 89 ). Job burnout and its three dimensionalities were negatively related to mental health( r= -0.331 ～ -0.662). With both occupational pressure and job burnout as predictors of mental health, only did job burnout negatively predict mental health (β = - 0. 698). Conclusion Both occupational pressure and job burnout can predicted policemen' general health.

Objective To investigate the effect of recombinant human erythropoietin (rhEPO) on the expression of glutamine synthetase (GS) of cultured rat retinal Müller cells in high glucose environment in vitro.Methods Mtüller cells were isolated from retinas of 10 Sprague-Dawley rats at postnatal day three to five by trypsin digestion,and were randomly divided into six groups,including normal control group,high glucose group,high glucose +5 U/ml rhEPO group,high glucose+ 10 U/ml rhEPO group,high glucose+ 20 U/ml rhEPO group,high glucose+40 U/ml rhEPO groups.After 48 hours,the apoptosis of retinal Müller cells were assayed by terminal transferase-mediated DNA end labelling assay,and the expression levels of GS protein were detected with semi-quantitative immunocytochemistry.Results Compared with the normal control group,the cell viability and GS protein were reduced while the cell death increased in Müller cells cultured in high glucose,the difference was statistically significant (t =27.4,P ＜ 0.01).Compared with the high glucose group,rhEPO treatment reduced the apoptotic Müller cells (t=857.2,2 374.6,2 473.2,2 537.7; P＜0.01),induced the expression of GS proteins (t=3.2,18.0,22.5,26.4; P＜0.05).Conclusions rhEPO can protect Müller cells from apoptosis under high glucose condition.The mechanism may be related to its function to up-regulate the GS protein expression,promote glutamic acid cycle,and reduce the excitotoxicity effects of high concentration of glutamate.
