中医医院现代化建设的思考

从中医现代化建设方面提出了几个注意的问题:强化改革开放意识,转变旧的封闭观念;重视医、教、研协同发展;加快传统科室的改造;加速陈旧设备的更新;基础设施建设应具有超前意识;开展对外交流,引进与输出相结合。     

Quantification of risk factors in Hospital infection at a surgical service

In this paper we have analyzed several risk factors for developing nosocomial infections at a Surgical Service of the Hospital Clinico Universitario San Cecilio 2>, based on a retrospective follow-up program designed specifically for this study. Of all patients admitted to the Service from January 1 to June 17, 1987, we examined the following variables: age, sex, cause of admission, emergency or non-emergency admission, operation and related variables. The overall rate of nosocomial infections was 16.46%. The most significant risk factors we found were operation , which had a linear correlation coefficient of '0.929 (p < 0.01) with hospital infection when stratified by its lenght, advanced age ( >60 years old), especially in non-operated patients, and chemoprophylaxis. Such risk factors were ascertained taking into account the confounding effect produced by the variables studied in this survey.Corresponding author.     

Cytogenetic analysis in human breast tumors

Cytogenetic analysis using C-, G-, and Ag-nucleolus organizer region (NOR) staining techniques, performed on established cell lines as well as directly processed breast tumor effusions, revealed that: 1) chromosome No. 1 is involved in translocation; 2) based on 1q translocation chromosome, breast tumors could be classified into two groups; and 3) double minutes and homogeneously staining regions may be present in breast tumor cells in vivo as well as in vitro, and that homogeneously staining regions may exhibit some heterogeneity in staining.     

Clinical information technology in hospitals: a comparison between the state of Iowa and two provinces in Canada

Despite the growing interest in adopting information technology (IT) in healthcare, the degree of technology sophistication varies among healthcare organizations. Changes in the health care sector and continuous pressure to improve the quality of care have driven the evolution of IT in hospitals. This paper provides an overview of clinical IT sophistication in a sample of U.S. hospitals, and compares clinical IT capacities in this sample with a sample of Canadian hospitals. The instrument used for the comparison measures three clinical dimensions of IT sophistication: functional sophistication, technological sophistication and integration level. Clinical areas that were considered include patient management, patient care activities and clinical support activities. The comparison between hospitals in Iowa and Canada shows differences in clinical IT sophistication between the two settings. Hospitals in Iowa appear to have more technologies but fewer computerized processes and integration of patient management activities. Technological sophistication however, was low in both samples. Our findings confirm the construct validity of the measurement instrument and show initial evidence of its generalizability. More initiatives using the instrument would lead to enhancement in IT assessment tools that can be used for evaluation of IT in relation to patient management and quality outcomes.     

The prognostic value of hypocholesterolemia in hospitalized patients

Clinical observations show that severe illness often leads to hypocholesterolemia. To verify this finding and to define the relationship between serum cholesterol and a patient's prognosis, a study was conducted in two large hospital populations. Of 24,000 and 61,463 adult patients (populations I and II) an average of 3.8% and 3.6% died in hospital, respectively. The mean serum cholesterol levels of patients who died was significantly lower than that of those who survived (163.6 mg/dl versus 217.8 mg/dl;P < 0.0001). The average cholesterol of surviving patients was similar to that of 6,543 healthy controls. During hospitalization serum cholesterol levels of 100 mg/dl were encountered in 1.2% and 3.6% of patients of populations I and II, respectively. The mortality of these hypocholesterolemic patients was about tenfold higher than average and showed a strong, inverse, linear relationship with serum cholesterol concentrations. Patients whose serum cholesterol level dropped to less than 45 mg/dl did not survive. These data show that in severely ill patients serum cholesterol may decline to very low concentrations, and the prognosis is reflected by the degree of hypocholesterolemia, which thus may serve as a clinically useful prognostic parameter.

Adrenaline turnover rates in the medial preoptic area and mediobasal hypothalamus in relation to the release of luteinizing hormone in female rats

The turnover rates of adrenaline in the medial preoptic area and mediobasal hypothalamus, areas which, respectively, include the cell bodies and terminals of luteinizing hormone-releasing hormone neurons, have been measured in female rats on pro-oestrus, the day of the preovulatory surge of luteinizing hormone, and on dioestrus, the preceding day. A rise in the rate of turnover was found in the medial preoptic area coinciding with the surge of luteinizing hormone in the late afternoon of pro-oestrus; the rate of turnover at this time was higher than at the same time on dioestrus. No changes in turnover rate were found in the mediobasal hypothalamus within either of these days.The results indicate that the adrenaline-containing projections to the preoptic area may be actively involved in the production of the spontaneous preovulatory surge of luteinizing hormone in rats.     

Nonrandom chromosomal changes in untreated retinoblastomas

The karotypic patterns of 15 retinoblastomas were examined. Five tumors were found to have two distinct stem lines and, therefore, the chromosomal patterns of 20 tumor cell lines are reported. Three nonrandom chromosomal changes, namely, a loss of a chromosome #13, the presence of an i(6p), or a trisomy of 1q were observed. The potential importance of these chromosomal changes in tumor development is discussed, particularly the loss of a chromosome #13 or the gain of an i(6p). At least one of the three chromosomal changes was found in 75% of the tumor lines analyzed.     

Egg allergy, influenza vaccine, and immunoglobulin E antibody.

In a study of 70 patients with asthma, rhinitis, and eczema, those giving a definite history of allergic reactions to egg more frequently showed positive skin tests to egg extracts (p = less than 0.003), the wheal diameters of which were significantly larger (p = less than 0.01) than in patients with only a possible or no such history. Patients with a definite history of egg allergy had significantly higher levels of specific IgE antibody against egg yolk, egg white, and allantoic fluid than patients in the other two groups (p = less than 0.005). Seven patients, all of whom had given a definite history of allergy to egg, were found to have positive skin prick tests to influenza vaccine, at the concentration used in medical practice. Two of these patients had previously been given influenza vaccine and both had developed adverse reactions. Of the 22 patients giving a definite history of allergy to egg, the 7 (35 per cent) with positive skin tests to influenza vaccine had significantly larger skin tests and higher levels of specific IgE antibody to the egg extracts than the group as a whole (p = less than 0.001). Allergic reactions to influenza vaccine are likely to occur in patients who have a definite history of allergy to egg and large skin prick test reactions or high levels of specific IgE antibody to egg extracts. Those at risk can best be identified by skin prick testing with egg extracts and undiluted influenza vaccine.
