A method for measurement of neutrophil function and opsonic activity by chemiluminescence (CL) was reported in this paper.The factors influencing the emission of CL were discussed. The experimental results suggested that CL depends on the concentration of luminol, the dilution of serum opsonin, the number of neutrophils and the environmental temperature. The optimum conditions defined in present study were: the concentration of luminol was 1?105M, the number of neutrophils 2?106/mml, the reactive temperature 37℃. According to the relationship between CL emission and the bactericidal activity of phagocytizing neutrophils, the measurement of CL may be used as a rapid, simple and usefull tool to determine the funetion of humoral-phagocyte axis.

Objective To analyze the effects of dopamine and norepinephrine on blood oxygen,heart rate and internal environment in patients with septic shock.Methods 80 patients with septic shock were collected.The patients were randomly divided into two groups.The control group was given dopamine treatment,the observation group was given dopamine and norepinephrine.Results The heart rate (HR)[(90.39±15.29)/min],ScVO2 index[(77.03±7.68)％] of the observation group were better than those of the control group (t=4.122 5,2.141 5,all P＜0.05).The urine volume[(94.05±22.39)mL/h],creatinine clearance rate[(53.12±14.45)mL/min] of the observation group were better than those of the control group (t=3.660 6,2.023 2,all P＜0.05).ConclusionDopamine combined with norepinephrine has significant effect on patients with septic shock,which can effectively improve the HR,ScVO2,urine volume,creatinine clearance rate and other indicators,thus to restore the patients'' internal environment.

Objective To investigate clinical significance and related factors of fluid-attenuated inversion recov?ery vascular hyperintensities (FVH) in transient ischemic attack (TIA) of carotid system. Method Data including general information and TIA risk factors was continuously collected from 142 patients with carotid system TIA from the depart?ment of neurology of Sheng jing Hospital affiliated China Medical University from January 2012 to February 2014.All pa?tients completed brain MRI including FLAIR and diffusion-weighted imaging (DWI)and MRA examinations within 72 hours after TIA. All patients were followed up for one month. Risk factors and FVH situations were analyzed based on clinical manifestations and DWI results. Result There were 87 male cases (61.27%)and FVH positive 57 cases (40.14%) among 142 cases with carotid system TIA (mean age 63.2±11.5). Logistic regression analysis revealed that the large intra?cranial carotid artery stenosis≥50%(OR=2.44,95%CI:1.09~5.49, P=0.03) and prior history of ischemic stroke (OR=3.88,95%CI:1.04~14.5, P=0.04) were independently associated with positive FVH. At one month followed-up, 40 cas?es (28.17%) of 142 patients progressed to acute cerebral infarction. Vulnerable plaque number in the contralateral carot?id artery (P=0.018), contralateral intracranial large vessel stenosis in MRA≥50%(P=0.007) and contralateral FVH oc?currence rate (P=0.001) were significantly higher in cerebral infarction group than in non-cerebral infarction group. Con?clusion FVH is common in carotid TIA patients, which is associated with intracranial carotid artery stenosis ischemic and previous history of ischemic stroke. Vulnerable plaque number of contralateral carotid artery, contralateral intracranial large vessel stenosis≥50%and the rate of occurrence of contralateral FVH may be associated with short-term progress leading TIA to acute infarction.

Patients with ischemic stroke is often accompanied by inflammtory response. Studies have suggested that toll-like receptor 4 (TLR4) has induced the occurrence,development and of ischemic stroke and secondary brain injury. This article reviews the toil-like receptor 4 signal transduction pathway and its roles in ischemic stroke in order to provide certain basis for the development of TLR4-targeted medication.

Telomeres are protective caps located at the ends of human chromosomes. Telomeres shorten with each successive cell di-vision in normal human cells, whereas they are continuously elongated by human telomerase in over 85%of tumors. This simple and attractive difference steers the development of anticancer drugs targeting telomeres and telomerase. Many promising current telo-mere/telomerase-targeting agents, such as GRN163L and GV1001, showed good therapeutic effect both in preclinical studies and phaseⅠ/Ⅱclinical trials. These agents have even entered phaseⅢclinical trials in patients with various tumors. Most therapeutics are more effective when used in combination with standard chemotherapies. Moreover, pharmacological interference with tumor-cell telomere biology to reduce telomere length and/or telomere stability could enhance the effectiveness and safety of radiotherapy. Therapeutics targeting telomere/telomerase may play a key role in radiotherapy in the era of personalized medicine in the future.

Objective To evaluate the gastroesophageal reflux symptom in patients who underwent continuous ambulatory peritoneal dialysis (CAPD) and the efficacy of proton pump inhibitor (PPI) in treating gastroesophageal reflux. Methods Fifty-eight CAPD patients with good clinical and complete dialyzed eondition,who was admitted to the hospital between Jan. 2008 and July 2008, were inquired about their gastroesophageal reflux symptoms using reflux disease questionnaire (RDQ). The patients who had RDQ≥6 and <12 were received esomeprazole 20 mg daily, while those with RDQ≥12 were received esomeparzole 20 mg twice daily. RDQ score was reevaluated 4 weeks after treatment.Results The common symptom was regurgitation (64.70%), followed by acid reflux (52.9 %), non-cardic chest pain (47.1. %) and heart burn (17. 6%). After 4-week treatment, the RDQ was significantly decreased (P< 0. 05). But there was no difference in outcome of treatment between patients with RDQ≥ 12 and RDQ< 12 (P=0. 059). Conclusion The gastroesophageal reflux symptom in CAPD patients can be relieved by PPI administration, but a larger clinical trial is needed to evaluate the course and efficacy of treatment.
