中风病简化辨证的哲学思考

中风病分阴证和阳证为纲辨治,不但有是充分的实践依据和理论基础,而且符合哲学的否定之否定定律。从中风病简化辨证的必要性,中风病阴阳辨证的发展,中风病的病因病机、证候属性可从阴阳两方面认识,中风病阴阳为纲辨证方法符合哲学否定之否定定律4方面进行了论述。     

“病中辨证”是证发展的必然

在疾病的发展过程中,一般存在着病和证的两种演变,相对于病而言,证有着更高层次的组织方式,有自身发展规律,反映的是机体整体状态。这种对证的诠释有利于中西医理论间的接轨,使证研究更容易被现代医学理论所接受,是中医进一步发展的要求,病证二者并不矛盾,而是互补,共同提供了对疾病的完整认识。     

无证可辨浅识及对策

辨证论治是中医学精髓。无证可辨的情况,究其原因,一方面与医者辨证方法和技能有关,另一方面确实存在无证可辨的现象。为提高辨证水平,医者既要重视病性特点、病因、六经病辨证特色;也要积极引入中医“病”的概念和微观辨证,因为中医辨病在特定情况下可弥补辨证的不足,而微观辨证的深入研究则可能为无证可辨提供客观依据。为此,才可在实践中正确处理无证可辨的尴尬,并使中医诊断学内容臻备。

Visual attention skills of premature infants with and without intraventricular hemorrhage

The relation between two medical complications associated with prematurity (intraventricular hemorrhage (IVH) and respiratory distress syndrome (RDS)) and visual attention skills of very low birth-weight (VLBW) infants were examined. Fourteen preterm VLBW infants with IVH and RDS, 9 preterms with RDS and no IVH, and 10 full-term infants matched on SES, sex, and race were assessed at 7 months of age (after correction for prematurity) for their ability to show a decremental response to a familiar visual stimulus and an increment in response to a novel visual stimulus. Measures of attention getting (turning toward a stimulus) and attention holding (sustained fixation on the stimulus after turning) were taken. On the attention-getting measures, IVH-RDS preterms had longer latencies than both the RDS-no-IVH preterm group and the full-term group. There were no group differences on attention-holding measures. The three groups did not differ in habituation to the familiar visual stimulus or discrimination of the novel stimulus. This study indicates that the early visual attention skills of preterm infants are differentially affected by specific types of prenatal complications.     

The long-term outcome of a personal network-oriented HIV prevention intervention for injection drug users: The SAFE study

Social influence processes have been found to affect numerous drug and health-related behaviors. We postulated that by using a network-oriented intervention it may be possible to capitalize on social influence processes to reduce human immunodeficiency virus (HIV) risk behaviors. The present study used an experimental study design for delivering a psychoeducational acquired immunodeficiency syndrome (AIDS) preventive intervention to injection drug sharing networks. Participants were recruited from the ALIVE study, an epidemiological study in Baltimore. In the present paper we examine the self-reported behavioral outcomes of 117 injection drug users 18 months after the baseline interview. HIV seronegative experimental participants reported significantly less frequent needle sharing and less injecting of heroin and cocaine than controls. In multiple logistic regression models of HIV seronegative participants, there was a significant negative association between assignment to the experimental group and the HIV-related behaviors of needle sharing and sharing of cookers in the prior 6 months; controls were 2.8 times more likely than experimentals to report needle sharing and were 2.7 times more likely to report sharing cookers. The results of this 18-month follow-up suggest that among injection drug users network-oriented interventions may be a promising approach to HIV prevention.     

Patterns of adolescent involvement in problem behaviors: Relationship to self-efficacy,social competence,and life events

Using a sample of 556 adolescents from a suburban community, patterns of various adolescent problem behaviors (e.g., delinquent behavior, smoking, use of alcohol or drugs) and their links to self-efficacy, social competence, and life events were examined. Cluster analysis was conducted to identify four subgroups of adolescents who showed distinct patterns of problem behaviors. These clusters were compared on the measures of self-efficacy, social competence, and life events. Overall results suggest there are meaningful links between adolescents’ problem behavior patterns and self-efficacy, the amount and quality of participation in various after school activities, and life events. For example, a subgroup of adolescents who showed uniformly low prevalence of all problem behaviors reported more positive academic self-efficacy, more active participation in sports and nonsports activities, more positive life events, and fewer negative events than adolescents who were involved in multiple problem behaviors. Implications for prevention and future research on adolescent problem behaviors are discussed.     

Cry analysis detects subclinical effects of prenatal alcohol exposure in newborn infants

The threshold, latency, and peak fundamental frequency (basic pitch) of crying were sensitive to the subclinical effects of prenatal alcohol exposure through the first month of postnatal life. Whereas infants with prenatal alcohol exposure showed a lower cry pitch and higher cry threshold at 2 days of age, higher pitched cries, typical of nervous system insult, were evident at 14 and 28 days. A longer latency was also evident at 14 days.     

Impaired tactual perception in children with Down's syndrome

Using standardized neuropsychological tests, tactual finger discrimination, graphaesthesia and stereognosis were studied in a group of 11 children aged 7–11 years with Down's syndrome (DS). All tasks were solved without visual control. The performance was subnormal in each test and the results of the stereognosis test were particularly poor. It was ascertained that the DS children could understand test instructions. Moreover, under visual control all objects used in the stereognosis test were handled correctly. The results suggest that tactual perception is subnormal in children with DS. The pathogenesis of the somatosensory abnormalities should be explored.     

Neurocognitive functioning in chronic fatigue syndrome

Although substantial research has been conducted on chronic fatigue syndrome (CFS) over the past decade, the syndrome remains poorly understood. The most recent case definition describes CFS as being characterized both by disabling fatigue and by subjective reports of difficulty with concentration and short-term memory. However, research into the neurocognitive and psychological functioning of individuals with CFS has provided mixed objective results. The current paper reviews studies that have examined the neurocognitive and/or psychological functioning of individuals with CFS. Changes in research design and instruments employed to study individuals with CFS are suggested.
