Effects of naokang erhao decoction on cognitive ability and hippocampal apoptosis-related proteins in diabetic rats / 中国中药杂志

<p><b>OBJECTIVE</b>To investigate the effects of Naokang Erhao decoction on the cognitive ability and the expression of Caspase-3, Bax and Bcl-2 proteins in hippocampus of type 2 diabetic rats.</p><p><b>METHOD</b>The diabetes mellitus (DM) rat model was produced by intraperitoneal injection of streptozotocin and fed with high fat and sucrose diet. The Naokang Erhao-treated rats were intragastrically given different doses of Naokang Erhao, whereas the control and DM model groups were given double distilled water for 4 consecutive weeks. Learning and memory abilities of rats were tested with the Morris water maze. The expression of Caspase-3, Bax and Bcl-2 proteins in hippocampal CA1 region was measured by immunohistochemistry.</p><p><b>RESULT</b>Both escape latency and swimming distance of type 2 DM rats were significantly prolonged in comparison of those in normal control (P < 0.01), and swimming time in the platform of previous quadrant was significantly shorter in model group (P < 0.01). Furthermore, the expression of Bcl-2 protein was decreased, while Caspase-3 and Bax in the hippocampus were increased compared with the control group (P < 0.01). Four weeks of treatment with Naokang Erhao decoction remarkably improved the learning and memory abilities of DM rats, increased the expression of Bcl-2 and decreased the expression of Caspase-3 and Bax in hippocampal CA1 region of model rats (P < 0.01 or P < 0.05).</p><p><b>CONCLUSION</b>Naokang Erhao decoction may inhibit apoptosis by increasing the expression of Bcl-2 and reducing the expression of Caspase-3 and Bax in the hippocampus, and this may be one of the mechanisms by which Naokang Erhao decoction improves cognitive ability in DM rats.</p>

Anxiety of Cerebral Infarction Patients with Sleep-disordered Breathing and Correlated with Sleep Quality / 中国康复理论与实践

@#ObjectiveTo investigate the anxiety and its effect on the sleep quality in patients with cerebral infarction and sleep-disordered breathing. Methods149 cerebral infarction patients were divided as 95 without sleep-disordered breathing and 54 with sleep-disordered breathing. They were evaluated with Hamilton Anxiety scale (HAMA) and Pittsburgh Sleep Quality Index (PSQI). ResultsPatients with sleep-disordered breathing showed higher HAMA overall score and factor scores of somatic anxiety and psychic anxiety（P<0.001）. In the factors of somatic anxiety, the scores of sensing, cardiovascular, gastrointestinal and autonomic nerve system were higher in patients with sleep-disordered breathing than those without sleep-disordered breathing （P<0.05）. In the factors of psychic anxiety, the scores of anxious mood, tension, fears, insomnia, depressed mood were higher in patients with sleep-disordered breathing（P<0.05）. PSQI overall score and all factor scores were also higher in patients with sleep-disordered breathing（P<0.001）. HAMA overall score as well as psychic anxiety and somatic anxiety scores were closely correlated with the PSQI overall score （P<0.001）. Somatic anxiety score was correlated with subjective sleep quality, sleep latency, sleep disturbance and daily dysfunction scores （P<0.05）. Psychic anxiety score was correlated with all the dimension scores of PSQI （P<0.01）. ConclusionCerebral infarction patients with sleep-disordered breathing appeared anxiety and worse sleep quality than patients without sleep-disordered breathing. Anxiety is closely related with sleep quality.

Relationship between Carotid Atherosclerosis and Cognitive Impairment or Quality of Life in Patients with Cerebral Infarction / 中国康复理论与实践

@#Objective To investigate the relationship between carotid atherosclerosis （CAS） and cognitive impairment, stroke-specific quality of life of patients with cerebral infarction. Methods Patients enrolled were divided into mild-to-moderate CAS group and severe CAS group after carotid ultrasound. They were assessed with Mini Mental State Examination (MMSE) and Stroke Impact Scale (SIS) Version 3.0. Results The scores of attention/calculation, comprehension, and total of MMSE, the mobile ability and hand function dimensions of SIS were all lower in severe CAS group than in mild-to-moderate CAS group （P<0.05）. Conclusion Carotid atherosclerosis may further impair the cognitive function and quality of life of cerebral infarction patients.

@#Objective To determine the clinical characteristics of comorbid anxiety and depression after cerebral infarction. Methods All the patients enrolled were divided into post-stroke comorbid anxiety and depression (PSCAD) group (84 cases) and the control group (121 cases). Their condition of smoke, alcohol intake, education background, carotid plaque and brain blood vessels were investigated, and they were evaluated with Hamilton Anxiety Scale (HAMA), Hamilton Depressive Scale (HAMD), Barthel index, and Mini-Mental State Examination (MMSE). Results There was not significant difference in condition of smoke, alcohol intake, education background, carotid plaque and brain blood vessels between these groups （P＞0.05）, but were in total scores and all the factors scores of HAMA and HAMD （P＜0.05）. PSCAD group showed more obvious anxious mood, depressive mood, tension, insomnia, cognitive impairment and autonomic nervous symptoms. Psycho-anxiety, soma-anxiety, despair, guiltiness, decreased interest were also more significant in the PSCAD group. The scores of MMSE and Barthel index were also impaired. Conclusion The cognitive function and daily living ability are worse in the patients with PSCAD. The prominent symptoms includes: anxious mood, depressive mood, tension, insomnia, cognitive impairment, autonomic nervous symptoms, soma-anxiety, despair, guiltiness, decreased interest.

Objective To analyze the relationship of Qi and blood deficiency syndrome's principal components of chronic fatigue syndrome (CFS) and TCM syndrome differentiation. Methods Syndrome principal components of 25 CFS Qi deficiency patients and 23 CFS blood deficiency patients were researched and combined with TCM syndrome differentiation, then their relationship were analyzed. Results There was significantly positive relationship between CFS Qi deficiency syndrome principal component 1 and CFS Qi deficiency syndrome. And there were significantly positive relationships between CFS blood deficiency syndrome principal component l, 2 and CFS blood deficiency syndrome. Conclusion The CFS Qi deficiency syndrome and blood deficiency syndrome's principal components were accord with TCM syndrome differentiation.

Correlative analyses of principal components of phlegm stasis syndrome (痰浊内阻证) and blood stasis syndrome (血瘀证) in cases with carotid atherosclerosis / 中国中西医结合急救杂志

Objective To analyze the internal relationship between phlegm stasis syndrome (痰浊内阻证) and blood stasis syndrome (血瘀证) in cases with carotid atherosclerosis. Methods The clinical data of 136 patients with atherosclerosis accompanied by phlegm stasis and blood stasis syndromes were collected from the investigation table of the 4 diagnostic methods in traditional Chinese medicine(TCM); the principal components of the clinical data were statistically analyzed, and the correlative relationships of these principal components were studied. Results There were two principal components of phlegm stasis syndrome, which were tz1 and tz2. And tz1 cumulated 42.645% to phlegm stasis syndrome, which could be considered as phlegm stasis in limbs and tunnel; tz2 cumulated 24.898% to phlegm stasis syndrome, which could be considered as phlegm stasis in the body that might impair the 7 orifices (such as eyes, ears, nose and mouth). And they could also be considered as special markers of phlegm stasis syndrome of carotid atherosclerosis. There were three principal components of blood stasis syndrome, which were xy1, xy2 and xy3. And xy1 cumulated 37.197% to blood stasis syndrome, which could be considered as blood stasis in the artery and tunnel; xy2 cumulated 21.627% to blood stasis syndrome, which could be considered as the blood outside the vessels located in the body and could obstruct tunnel and could not nourish muscle and skin; then, xy3 cumulated 13.685% to blood stasis syndrome, which could be considered as the blood stayed in the brain and could not nourish brain and might reflect as a special marker of blood stasis syndrome of carotid atherosclerosis. There was significant positive correlative relationship between phlegm stasis syndrome principal component 1 and blood stasis syndrome principal component either 1 or 2 (P
