Both basic and clinical studies have confirmed that inflammatory response plays an important role in the occurrence and development of atherosclerosis (AS) as well as its caused clinical events.The aggregation phenomena of T lymphocytes,macrophages and dendritic cells (DCs) can be observed in intima and atherosclerotic plaques in the event of atherosclerosis.As the most important antigen-presenting cells activating T lymphocytes,DCs have the important functions of determining T lymphocyte activation,apoptosis,and aggregation.This article reviews the correlation between DCs and atherosclerotic lesions.

AIM: To study the effect of peach seed (semen Persicae) on gene expression of mouse with sarcoma 180 by means of DNA microarray. METHODS: DNA microarrays were made by spotting PCR products of 4096 mice cDNA noto a specially treated glass slides. The probes were prepared by labeling experimental and control group tumor tissue mRNA with Cy3 dUTP and Cy5 dUTP separately through reverse transcription. The arrays were then hybridized against the cDNA probe mixture and the fluorescent signals were scanned. The data obtained were analyzed from two repeated experiments. RESULTS: 64 genes were obtained by computer processing. CONCLUSION: These genes identified through this approach are considered as potential candidates for PSPA anti tumor effect.

Objective To develop a balloon-type head fixation pillow for interventional neuroradiology operation.Methods Some radiotransparent sponge with high elasticity and strength and some nonopaque cloth with high skin compatibility were employed to make pillow base adaptable to the posterior fossa, neck and shoulder. A inflatable balloon made of anti-tensile airtight nylon was used to fix the underjaw.Results The fixation pillow gained advantages over the common one in imaging times, X-ray exposure dose and abnormal condition.Conclusion The head fixation pillow may decrease operating time, exposure dose and complications during interventional neuroradiology operation, and thus is worth popularizing clinically.

p53 (encoded by TP53) is undoubtedly one of the most extensively studied genes and proteins. It is a highly potent transcription factor which, under normal circumstances, is maintained at low level. Both genotoxic and non-genotoxic stresses can induce p53 stabilized leading to changes in the expression of p53-responsive genes. The biological outcome inducing this pathway can be either growth arrest and apoptosis or senescence to maintain the integrity of the genome or to delete the damaged cells. The biochemical activity of p53 itself and the cellular environment govern the choice between these outcomes in a cell type- and stress-specific manner. So, p53 is a pivotal tumour suppressor and a mainstay of our body's natural anticancer defence. This review could provide some useful information for further study on the mechanisms of tumorigenesis and its progression, and also could contribute to the discovery of antitumor agents.

BACKGROUND: Neonatal hypoxic ischemic encephalopahty(NHIE) is a common neonatal disease, which could cause cerebral palsy, inferior intelligence and convulsion. At present, usual examinations for this disease are CT.MRI and single photon emission computed tomography(SPECT), etc.OBJECTIVE: To investigate the character of SPECT image of NHIE, and compared with CT and MRI as well to provide a theoretical gist for function surveillance and early intervention of NHIE.DESIGN: An observatory comparative study based on NHIE patients and normal neouates as control.SETTING: Department of nuclear medicine in a medical university hospital.PARTICIPANTS: Thirty neonates hospitalized in the Department of Pediatrics, Affiliated Hospital of Jining Medical College between September 1998 and October 2000 were selected as observation group with 23 males and 7 females. Another 10 normal neonates including 7 males and 3 females were randomly selected from same period into control group.METHODS: SPECT brain blood perfusion was conducted in the subjects of two groups and the results were compared with that of CT and MRI.MAIN OUTCOME MEASURES: ① comparison of SPECT brain blood image features between NHIE and normal neonates; ② comparison of SPECT images and CT, MRI results. RESULTS: In 22 NHIE cases who received SPECT, CT and MRI simultaneously, mild group had 7 cases, and positive cases of SPECT, CT or MRI was 7, 3 or 5; moderate group had 10 cases, and positive cases of three methods was 10, 8 or 9; severe group had 5 cases, the all of them were positive in all three examinations. The total positive detectable rate of SPECT, CT or MRI was 100, 72.73% or 86. 36%. There was no significant difference of sensitivity between SPECT and MRI in mild group, while there was significant difference between SPECT and CT(x2 = 3.95, P < 0.05);there was no significant difference among three methods in either moderate group or severe group(x2 =0. 83, P > 0.05).CONCLUSION: SPECT brain blood perfusion image is a quite sensitive method for the surveillance of NHIE, which can provide imageological reference for the evaluation of its prognosis and early intervention.

Objective To compare the diagnostic value of dual-phase 99Tcm-MIBI scintigraphy and color Doppler ultrasonography for localizing ectopic parathyroid lesions in patients with HPT secondary to chronic renal failure (CRF-HPT).Methods Medical records of 368 CRF-HPT patients (204 males,164 females,age range:12-76 years) from January 2011 to April 2015 were retrospectively analyzed.Pathological results was used as the gold standard for the diagnosis of HPT.The sensitivity and specificity of dualphase 99Tcm-MIBI scintigraphy and color Doppler ultrasonography for the diagnosis and localization of ectopic parathyroid lesions were studied and compared by x2 test.Results A total of 1 398 positive lesions were found in 356 patients by dual-phase 99Tcm-MIBI scintigraphy,and 54 ectopic lesions occupying 3.9%(54/1 398) of positive lesions were detected by delayed planar imaging or SPECT/CT fusion imaging in 45 patients.Most of them (n =53) were confirmed by pathology.While only 966 positive lesions were found in 254 patients and no ectopic lesions were identified by color Doppler ultrasonography.The diagnostic sensitivity and specificity of dual-phase 99Tcm-MIBI scintigraphy for CRF-HPT lesions were 97.2%(1 375/1 415) and 53.1%(26/49),respectively.The corresponding parameters of color Doppler ultrasonography were 66.4% (940/1 415) and 46.9% (23/49),respectively.The specificity of ectopic lesion localization by radionuclide imaging was 98.1% (53/54).The accuracy of dual-phase 99Tcm-MIBI scintigraphy was significantly higher than that of color Doppler ultrasound in lesion localization (x2 =20.8,P < 0.05).Conclusion Compared to color Doppler ultrasonography,99Tcm-MIBI scintigraphy is more sensitive in identifying the positive lesions and more specific in localizing the ectopic parathyroid lesions in patients with CRF-HPT.

OBJECTIVE:To provide reference for implementing pharmaceutical care for secondary prevention of patients with myocardial infarction and improving medication compliance by clinical pharmacist. METHODS:A questionnaire survey was con-ducted for 200 secondary prevention patients with myocardial infarction in our hospital,and divided into good medication compli-ance group and poor medication compliance group by Morisky-Green(MG)standard scoring evaluation, and the reasons affecting the medication compliance were statistically analyzed. RESULTS:Totally 200 questionnaires were sent out,200 were effectively re-ceived with effective recovery of 100%. 137 patients showed good medication compliance and 62 patients showed poor medication compliance,there were statistically significant differences in the age,monthly income,whether there was a medical insurance or not,whether they live alone or not and whether they had more than 4 oral drugs between 2 groups(P<0.05). The reasons of poor medication compliance were forgetting to take the medicine,too many kinds of medicine,too expensive to afford the medicine, lacking the knowledge of the disease and poor medication guide. CONCLUSIONS:The poor medication compliance of patients with secondary prevention of myocardial infarction is closely related with elder age,low income,no medical insurance,living alone,and taking more than 4 kinds of medicine. Clinical pharmacists should play their professional expertise,repeatedly supervise patients'medication compliance and finally improve the efficacy and patients'quality of life.
