BACKGROUND: Cognitive function of simple leukoaraeosis (LA) and subcortical arterioselerotic encephalopathy (SAE) is a part of research in cerebrovascular neuropsychology, however, there is no contrast study on cognitive function between the two diseases. OBJECTIVE: To investigate the different features in cognitive function among patients with simple leukoaraeosis, subcortical arterioselerotic encephalopathy and simple leukoaraeosis combined with cerebral infarction. DESIGN: Randomized controlled observation SETTING: Department of Neurological Medicine, Qilu Hospital, ShandongUniversity. PARTICIPANTS: A total of 91 cases of patients with cerebrovasculardisease diagnosed in Department of Neurological Medicine of Qilu Hospital of Shandong University from March 1997 to May 2000 were selected. All the patients participated in the observation voluntarily. They were divided into 3 groups according to the type of disease, with 27 cases in simple leukoaraeosis group, 33 cases in subcortical arterioselerotic encephalopathygroup and 31 cases in simple leukoaraeosis + cerebral infarction group.Additionally, 30 healthy cases were selected as control group. All the subjects in the above groups participated in the observation voluntarily. METHODS: Assessment on cognitive function and memory ability was conducted on the subjects in each group, and contrast analysis was performed. Mini-mental state examination was used for detecting cognitive function. Patients whose score was less than 17, 20, 22, 23 respectively according to different educational degree (illiteracy, primary school, middle school, university), would be diagnosed as dementia. Clinical me mory scale A edited by Psychology Institute of Chinese Academy of Medical Sciences was used for detecting memory ability including associative learning, directive memory, recognition of nonsense figure, image free recall and portrait characteristics associative recall. Conversed the above 5 items of detecting results to scores of scales and calculated out the memory quotients. MAIN OUTCOME MEASURES: State of cognitive disorder and scoresof mini-mental state examination and clinical memory scale of subjects in each group. RESULTS: All the 91 cases of patients with cerebrovascular disease and 30 healthy control cases entered results analysis without any drop out. ① Comparison of the state of cognitive disorder among subjects in each group: There were 21 cases of mild cognitive disorder (77.8%) in simpleleukoaraeosis group, 8 cases of moderate cognitive disorder (24.2%) and 25 cases of dementia (75.8%) in subcortical arterioselerotic encephalopathy group, 6 cases of moderate cognitive disorder (19.4%) and 24 cases of dementia (77.4%) in simple leukoaraeosis + cerebral infarction group. ② Comparison of the scores of mini-mental state examination among and clinical memory scale: Scores of the two scales in simple leukoaraeosis group, subcortical arterioselerotic encephalopathy group and simple leukoaraeosis + cerebral infarction group were significantly lower than those in healthy control group (t=2.14-3.81, P ＜ 0.05-0.01). The scores in subcortical arterioselerotic encephalopathy group and simple leukoaraeosis+ cerebral infarction group were significantly lower than those in simple leukoaraeosis group (t=2.13-3.37, P ＜ 0.05-0.01).CONCLUSION: ① The cognitive impairment in simple leukoaraeosis is mainly mild cognitive disorder. ② The cognitive impairments in subcortical arterioselerotic encephalopathy and simple leukoaraeosis + cerebral infarction are mainly moderate cognitive disorder and dementia which are obviously severer than mild cognitive disorder. Cognitive function can be used as reference indicator for assessing simple leukoaraeosis and subcortical arterioselerotic encephalopathy.Liang LP, He Y, Guo HZ.A contrast between the cognitive function of patients with simple leukoaraeosis and subcortical arterioselerotic encephalopathy.

This article was aimed to study the effect of Baohe granules for patients with chronic heart failure (CHF) of traditional Chinese medicine (TCM) syndrome and the effect of gastrointestinal hormone secretion. Patients with CHF were used as the object of study. A total of 80 selected patients were divided into 2 groups. The control group was treated with western medicine anti-heart failure therapy. The treatment group was treated with the combination of Baohe granules. All patients were compared in aspects of TCM efficacy, symptom score and serum gastrin, motilin secretion after two-week medication. The results showed that both treatments can significantly improve the TCM syn-drome and symptom total score of CHF patients. And the effect of the treatment group with Baohe granules was bet-ter. The TCM single symptom integral was also obviously improved in the treatment group combined with Baohe granules, which included heart palpitations, shortness of breath, abdominal distension, and loss of appetite. The GAS and MTL levels of CHF patients were significantly increased in the treatment group. It was concluded that the treat-ment combined with Baohe granules can improve CHF patients with TCM syndromes, symptoms and gastrointestinal hormone secretion. Thus, it contributed to the stability of the disease condition. It can slow the disease progression and improve prognosis. So it is worth using widely in the clinical practice.
