老年高血压患者脉压与急性心肌梗塞的关系

目的探讨老年原发性高血压（ET）患者脉压与急性心肌梗塞（AMI）的关系。方法观测45例老年高血压病合并急性心肌梗塞患者的收缩压（SBP）、舒张压（DBP）及脉压（PP），以31例老年单纯高血压患者（冠脉造影排除冠心病）作对照组，进行比较。结果并发急性心肌梗塞组，其脉压较单纯高血压组明显增高。结论脉压与老年人急性心肌梗塞密切相关，对老年人高血压的治疗更要注重控制脉压。

Encouraging Underscreened Women to Have Cervical Cancer Screening: The Effectiveness of a Computer Strategy

Background.Computers that collect data from patients and provide both patients and practitioners with printed feedback on a range of health risks are a tool for assisting general practitioners with preventive care. This study assessed the impact of computer-generated printed feedback on cervical screening among women who were underscreened for cervical cancer.Method.Female attenders at two Australian general practices were randomly allocated to Experimental or Control groups. Women in both groups completed a health risk survey on a touch screen computer prior to their consultation. Those in the Experimental group received printed pages summarizing their results, including their eligibility for cervical screening and last Pap test, for themselves and their doctor. The number and proportion of underscreened women who had a Pap test in the 6 months after completing the computer survey, as determined by pathology records, were examined.Results.Of the 679 participants, 139 were classified as underscreened on the basis of self-report (74 Experimental, 65 Control) and 272 on the basis of their pathology records (148 Experimental, 124 Control). Overall about one-third of women had a test in the 6-month period, and the differences between the groups were not significant for women overall (18–70 years) or for women 18–49 years. Among women 50–70 who were underscreened based on self-report, those receiving the printout were more likely to have a Pap test in the next 6 months (P< 0.05). This pattern was also evident, but did not reach statistical significance, for older women who were underscreened based on pathology records.Conclusions.We are unable to draw conclusions regarding the effectiveness of the computer system due to the modest proportions of women screened, the small numbers, and the fact that the computer survey may have created an intervention effect in the Control group. As the study suggests the computer system is acceptable to women and may be effective for encouraging screening among older women, further exploration of the system is desirable.     

The human major histocompatibility complex class Ib molecule HLA-E binds signal sequence-derived peptides with primary anchor residues at positions 2 and 9

Human histocompatibility leukocyte antigen E (HLA-E) and mouse major histocompatibility complex (MHC) class Ib antigen, Qa-1, share the same substitutions at two normally conserved positions 143 and 147, which are likely to affect binding of the C terminus of peptides. Qa-1 is able to bind a peptide derived from the leader sequence of H-2 D and H-2 L molecules. We developed a peptide binding assay in vitro to compare the binding specificity of HLA-E with the mouse MHC class Ib molecule Qa-1. We demonstrate that HLA-E binds, although poorly, the peptide which binds to Qa-1 and that it also binds nonamer signal sequence-derived peptides from human MHC class I molecules. Using alanine and glycine substitutions, we could define primary anchor residues at positions 2 and 9 and secondary anchor residues at position 7 and possibly 3.     

经口摄入高硒镉对大鼠肝,肾组织中镉,锌,铜含量影响的研究

选用4周龄SD大鼠,经口染毒高硒(5.68mg/kg)、富硒(0.73mg/kg)和(或)高镉(33.3mg/kg)12周,并分别在实验的第3、6、9、12周末各处死一批大鼠,研究经口摄入高硒高镉对大鼠肝、肾组织中镉、锌、铜含量的影响。结果表明:同时摄入高硒高镉组大鼠体内镉蓄积明显低于单纯摄入高镉组;对单独摄入高硒、高镉所诱导的大鼠肝脏锌含量增加表现为拮抗作用;对单独摄入高硒所致大鼠肾脏锌含量降低的影响表现为拮抗作用;对单独摄入高硒、高镉所致大鼠肾脏铜含量增加的影响表现为协同作用。     

老年冠心病患者实施健康教育的远期效果分析

目的：探讨老年冠心病患者实施健康教育的远期效果。方法：110例老年冠心病患者被随机分为健康教育组（教育组）及对照组，每组各55例。在常规治疗的基础上教育组在住院期间及出院后4年内给予健康教育处方结合口头卫生宣教及科普板报知识等经常性的健康教育活动，而对照组不予健康教育。结果：教育组患者对冠心病知识的了解情况、饮食控制情况、规律服药治疗情况比对照组好（P＜0．01），出院后再次住院次数比对照组少（P＜0．01）。而情绪及吸烟量控制两组无显著性差异（P＞0．05）。结论：对老年冠心病患者实施经常性的健康教育是控制疾病恶化的重要措施。

Frequency, nature and determinants of pharmaceutical consultations provided in private by Dutch community pharmacists

OBJECTIVE: According to a report published by the federation of Dutch patients' associations, patients would like to see a pharmacist, who acts more as a personal adviser. This raised the question, how often Dutch community pharmacists have personal consultations with their patients in daily practice, on which factors this depends, and what kind of topics are discussed during these meetings. SETTING: Community pharmacies in the Netherlands. METHOD: A questionnaire was distributed among 800 randomly selected pharmacies. Questions were restricted to consultations characterized by one-to-one contact, drug therapy related content, and adequate privacy. These consultations were labelled as pharmaceutical consultations in private to distinguish them from other contacts between pharmacists and patients. MAIN OUTCOME MEASURE: Number, content, and character of consultations. RESULTS: 198 (24.8%) community pharmacies responded. The pharmacists provide an average of roughly 1.2 consultations in private per working day. The vast majority of respondents provided face-to-face and telephone consultations (94.4 and 91.9%, respectively), only a minority gave consultations by e-mail (30.8%). These consultations primarily dealt with topics related to medication safety. The mean overall time spent was 290 min per month. A relatively high frequency of personal consultations was significantly associated with the absolute number of full-time equivalent pharmacists in the pharmacy. CONCLUSION: The frequency of pharmaceutical consultations in private is low, but may be improved by reorganisation of the pharmacist's activities. The possibility of personal consultations by e-mail is not yet well-developed. Further research is needed to assess the patient's view of pharmaceutical consultations in private.     

Is neighbourhood deprivation a risk factor for gestational diabetes mellitus?

AIMS: To assess the relationship between neighbourhood deprivation and the rate of gestational diabetes mellitus (GDM) using routinely collected data from a clinical information system, in Plymouth, UK. METHODS: Between 1 January 1996 and 31 December 1997, 3933 women residing within the Plymouth Primary Care Trust (PCT) were screened for GDM using indices of neighbourhood deprivation and prevalence of GDM. Areas (n = 43) were classified according to the Townsend index, measuring material deprivation. Pregnant women with and without GDM were compared. RESULTS: The prevalence of GDM was 1.7%[95%, confidence interval (CI) 1.20, 2.11]. The prevalence of GDM ranged from 1.05% (95% CI 0.60, 1.70) in the most deprived to 2.10% (95%, CI 1.34, 3.13), in the least deprived neighbourhood. Crude rates decreased by 50%[relative prevalence (RP) (95% CI) 0.50 (0.27, 0.94); P = 0.06] amongst those living in the most-deprived compared with those living in the least-deprived areas. Using a stepwise binary logistic regression model, older age at delivery significantly increased the risk of developing GDM. [RP (95%, CI) 1.09, (1.04, 1.13)]. Townsend deprivation score had no significant independent association with GDM when other covariates were considered. CONCLUSION: These data suggest that the neighbourhood context in which women live has no impact on the risk of GDM. Diabet.
