Objective To explore the factors influencing pneumococcal vaccination uptake among the el-derly people in Guangzhou. Methods A survey by questionnaire was performed among 827 subjects aged 60 years or above and living in Guangzhou for five consecutive years. Chi-square test and multiple logistic regression analysis were applied to identify factors influencing pneumococcal vaccination uptake among the elderly. Results The positive factors for vaccination uptake among the elderly people included age of over 70 years (OR=1.677, 95%CI: 1.156 ~ 2.434), mental workers (OR = 1.837, 95%CI: 1.214 ~ 2.779), education background of over-three-year-course training (OR=1.769, 95%CI:1.039~3.012), and history of chronic diseases (OR=1.659, 95%CI:1.096~2.512) were positively associated with pneumococcal vaccination uptake. Monthly disposable income was not an influencing factor (OR=1.420, 95%CI: 0.895 ~ 2.251). Conclusion Strengthened publicity of pneumo-coccal vaccination among the elderly people and flexible measures tailored to the needs of different groups are rec-ommended in order to improve pneumococcal vaccination uptake among the elderly people.

There are many different opinions about the taxonomy of plant pathogenic coryneform bacteria since they were departed from genus of Corynebacteria. In recent years, they were classified into 5 genus, including Clav-ibacter, Curtobacterium, Arthrobacter, Rhodococcus and Rathayibacter. Some new points of view about their taxonomy have been published thereafter. The changing of taxonomy is maily because of the methods'altering from old to new molecular and polyphasic taxonomy, and the latter is in continuously development. Taxonomy of plant pathogenic coryneform bacteria somehow depends on the cooperation of phytopathologists, microbilogists and other scientists.

Background and Objective Keshan disease is clinically characterized as a dilated eardiomyopathy. We analyze the prevalence trend during last decade of hypertension and Keshan-disease in Yangzhuang village which was a Keshan-disease epidemic area.Method The survey including medical history,blood pressure and ECG were carried out every two years during the follow up 13 years.Results During follow up period,the total detection rate(hypertension:13.4 % vs Keshan-disease:10.7 %,?~2=8.555,P=0.002)and the accumulative rate of hypertension were higher than those of Keshan-disease,which was on the contrary to that before 1993,when increasing rate of Keshan-disease was higher than hypertension.Furthermore,the accumulative increasing rate of hypertension was 240.0%,which was higher than the national average level during corresponding period with no significant differences between female and male.Conclusion The detection rate of hypertension in Keshan disease epidemic area was higher than the average rate nation-wide.Whether the hypertension prevalence was re- lated to Keshan-disease needs further investigation.

[Abstract ] Objective Pelvic radiation disease(PRD) is multiple injuries in more than one organ resulted by pelvic radio-therapy.Patients have the symptoms of frequent feces and fecal incontinence after the resection of small bowel lesion .Sugeries on PRD patients were mainly distal ileum and ilieocecal valve resections , while the most susceptible part of pelvic radiation injury is rectum . However , little research has been done concerning PRD patients′anorectal functions .This study was mainly to evaluate the anorectal function of cervical cancer patients with PRD in order to provide evidence for the therapy and prognosis of PRD . Methods Cervical cancer patients with PRD in need of small bowel resection who hospitalized in our department from January 2014 to January 2015 were collected as patient group , while people from outpatient physical exam group were selected as control group according to the exclusion criteria of hypertension , diabetes, constipation and unrelaxed pelvic floor syndrome .PDR group and control group were matched according to age.All subjects underwent colonoscopy and anorectal manometry .Rectal radiation injury was estimated on the basis of colonoscopy results.Anorectal manometry results of PRD group and control group were analysised statistically . Results PRD group and control group both included 20 women without stenosis or obstruction in rectum .Significant difference was found between PRD group and con-trol group in anal resting pressure (47.23 ±9.08 mmHg vs 58.25 ±9.24 mmHg, P<0.05), anal maximum squeezing pressure (47.23 ±9.08 mmHg vs 58.25 ±9.24 mmHg, P<0.01), anal distension pressure (23.30 ±12.49 mmHg vs 39.10 ±9.99 mmHg, P<0.01), rectal defecation pressure(22.85 ±16,69 mmHg vs 50.90 ±9.14 mmHg, P<0.01) and maximum tolerated rectal volume (112.85 ±51.34 mL vs 173.50 ±48.15 mL, P<0.01).There was no significant difference between the two groups as to the lenghth of functional sphincters(P=0.313),rectum initial threshold(P=0.416) and rectal defecation threshold(P=0.161). Conclusion Ionization radiation that injures PRD patients′internal anal sphincters and external anal sphincters also reduces maximum tolerated rec -tal volumes preoperatively .It′s necessary to assess the muscles and nerve functions of anorectum before intestinal surgery in order to make a proper operation plan which will improve PRD patients′life quality.

Objective To stuay CT findings of adrenal gland trauma(AGT).Methods The CT images of adrenal gland trauma which were found in 1712 patients who had emergency abdominal CT examinations for assessment of blunt force trauma were analyzed restrospectively.Results Among 1712 cases.we identified 29 patients(1.7%)with adrenal gland traumatic lesions.A total of 32 lesions were found.Twenty-six lesions were unilateral(23 right-sided,3 left-sided),and 3 cases were bilateral(6 lesions).Main CT findings were as followed:(1)Adrenal hematomas appeared as discrete round or oval masses expanding the adrenal gland in 22 patients with 25 lesions.The lesions were hyperdense or of homogeneous density in plain scan and did not enhance in three-phase contrast-enhanced dynamic scan.The splayed adrenal limbs around hematoma were enhanced significantly as eurvilinear structures.(2)Mild to moderate uniform swelling of gland was shown in 4 cases.(3)Diffuse irregular hemorrhage obliterating the gland was shown in 3 cases.Contrast extravasation was shown in 1 case,which was active bleeding from the broken adrenal gland proven by operation.Associated CT findings included strand-like hemorrhage of the periadrenal fat and posterior pararenal hemorrhage mimicking thickened diaphragmatic crus.The concurrent injuries of ipsilateral thorax or/and abdomen were found in 25 patients.Conclusion The AGT has typical CT findings.Familiarity with characteristic CT findings of adrenal trauma is essential for the radiologist to avoid misdiagnosis.

OBJECTIVETo assess the accuracy of computed tomography angiography (CTA) in quantifying atherosclerotic area in the vascular wall of the carotid artery in comparison with high-resolution magnetic resonance imaging (MRI).

METHODSEighteen subjects (15 males and 3 females aged 63-/+8 years) with >or=50% stenosis in at least one carotid artery were enrolled in this study. CTA and high-resolution MRI scans (in-plane pixel size of 0.25 mmx0.25 mm for both) were conducted within 1 week on a multi-slice spiral CT scanner and a 1.5T MR scanner (Signa, GE Medical Systems), respectively. CTA images were matched with MR images with the carotid bifurcation as the mark. For each patient, multiple matched slices with carotid atherosclerotic plaques in the bilateral carotid arteries were selected to measure the outer wall boundary (OWB) area, lumen area and wall area. Bland-Altman analysis and Pearson correlation coefficients were used to analyze the correlations of the area measurements between CTA and high-resolution MRI.

RESULTSA wide range of lesion size (vascular wall area) was found in these patients. Strong correlations were noted between CTA and high-resolution MRI with the correlation coefficients for OWB area, lumen area and wall area of 0.98, 0.98 and 0.96, respectively. The mean differences between CTA and high-resolution MRI were 0.16-/+5.71 mm(2), 4.47-/+1.44 mm(2) and -4.31-/+5.73 mm(2) for OWB area, lumen area and wall area, respectively.

CONCLUSIONCompared to high-resolution MRI, CTA is also a reliable method to measure carotid vascular wall area. CTA might become an alternative modality to high-resolution MRI for follow-up examination of patients with carotid artery atherosclerosis, especially in uncooperative patients or patients with contra-indications for MRI.

OBJECTIVETo evaluate the capability of magnetic resonance imaging (MRI) using different sequences in displaying atherosclerotic carotid plaque composition.

METHODSThirty-five patients received pre- and post-contrast carotid MRI examination on a 3.0T scanner. TOF, T(1)W, T(2)W, PDW and CE-T(1)W were used for identifying the positive and negative cases for the plaque composition (lipid-rich necrotic core, intraplaque hemorrhage and calcification), and their respective sensitivity, specificity and Cohens κ with 95% CI for displaying the components of the plaques were calculated.

RESULTSA total of 74 plaques were found in the 35 patients, and after exclusion of 6 plaques for a thickness below 3 mm, 68 plaques were included for the analysis. Lipid-rich necrotic core were found in 57 plaques, intraplaque hemorrhage in 30 plaques, and alcification in 43 plaques. CE-T(1)W was the optimal sequence for displaying lipid-rich necrotic core with a sensitivity of 100%, specificity of 90.9%, and κ value of 0.944. Both T(1)W and TOF reliably showed the intraplaque hemorrhage, but the former had a greater sensitivity (100%), specificity (92.1%), and κ value (0.911). Of all the 5 sequences, TOF was the best to show calcification with high sensitivity (100%), specificity (92%), and κ value (0.936).

CONCLUSIONCE-T(1)W is the best sequence to show lipid-rich necrotic core with high sensitivity and specificity. T(1)W and TOF show a high level of agreement with the standard to show the intraplaque hemorrhage. TOF is more sensitive and accurate than the other sequences in displaying calcification. The combination of T(1)W, TOF and CE-T(1)W allows accurate evaluation of each component of the plaque.
