ABSTRACT

This study aimed to observe the general state and changes in pathophysiological indexes of multiple cerebral infarction rat model with Qi-deficienty and Blood-stasis syndrome. Rats were randomly divided into 4 groups(with 30 in each group): the normal group, the sham group, the model group and the Yiqi Huoxue recipe group. Rats in the model group and Yiqi Huoxue group were provided with interruptable sleep deprivation for 7 days before the multiple cerebral infarction operation, and followed by another 4 weeks of sleep deprivation; rats in the Yiqi Huoxue group were intragastrically administrated with drug at a dose of 26 g·kg⁻¹, once a day for 4 weeks. The general state was observed, and the pathophysiological indexes were measured at 48 h, 2 weeks and 4 weeks after administration. The results showed that rats in the normal group and the sham group represented a good general state and behaviors, with a normal morphological structure of brain tissues; rats in the model group featured yellow fur, depression, accidie, loose stools and movement disorder, with obvious brain histomorphological damage, which became aggravated with the increase of modeling time; rats in the Yiqi Huoxue group showed release in the general state and above indexes. Compared with the sham group at three time points, rats in the model group showed decrease in body weight, exhaustive swimming time and RGB value of tongue surface image, and increase in whole blood viscosity of the shear rate under 5, 60 and 150 S⁻¹, reduction in cerebral cortex Na⁺-K⁺-ATPase, Ca²⁺-ATPase activity and contents of 5-HT, rise in TXB2 levels and decline in 6-keto-PGF1a in serum(<0.05, <0.01). Compared with the model group, rats in the Yiqi Huoxue group showed alleviations in the above indexes at 2 w and 4 w(<0.05, <0.01). The results showed that the characterization and pathophysiological indexes in the multiple cerebral infarction rat model with Qi-deficiency and blood-stasis syndrome were deteriorated; Yiqi Huoxue recipe could significantly alliviate the abnormal conditions, which suggested of the model was stable and reliable and the pathophysiologic evolutionary mechanism might be related to energy metabolism dysfunction, vasoactive substance abnormality and changes in neurotransmitters.

ABSTRACT

Nausea is special in the symptoms, and is different from hiccups and vomiting. The main symptom is that the patients throw up the indigested food from the stomach regularly--if the patients have a dinner, they will throw out it in the next morning, or if the patients have a breakfast, they will throw out it at night. Nausea is common in clinic, and different physicians may use different treatment methods for it. This disease also cannot be treated efficiently and may happen repeatedly with the western medicine. In this study, the composition principles of prescriptions in past traditional Chinese medicine for nausea were analyzed and summarized by using traditional Chinese medicine inheritance support system(V2.5), hoping to provide guidance for clinical drug use and summarize the basic rules for treatment of nausea.The prescriptions for nausea in "the prescription of traditional Chinese medicine dictionary" were selected, and the information was entered into the traditional Chinese medicine inheritance support system(TCMISS) to build a database. Data mining methods such as frequency statistics, association rules, complex system entropy clustering were used to analyze and summarize the composition principles of these prescriptions. The herb frequencies of the prescriptions were finally determined; herbs with higher use frequencies were obtained; and the association rules between herbs were found. 19 commonly used herb pairs, 10 core combinations and 10 newly developed prescriptions were found. The basic pathogenesis of nausea in traditional Chinese medicine is the weakness and coldness of spleen and stomach, and the Qi adverseness of stomach. Generations of physicians' main therapeutic method for nausea is mainly to warm the middle and invigorate the spleen, lower Qi and regulate stomach. The commonly used herbs for nausea are ginger, ginseng, large head attractylodes, tuckahoe, licorice, and appropriately supplemented with the herbs of eliminating dampness and eliminating phlegm, and regulating Qi-flowing for harmonizing stomach. In addition, it shall be treated according to the different accompanying syndromes such as phlegm, blood stasis, and yin deficiency.

ABSTRACT

<p><b>OBJECTIVE</b>To observe the effect of formula of removing both phlegm and blood stasis (TYTZ) in inhibiting the inflammatory reaction in Chinese mini-swine with coronary atherosclerosis.</p><p><b>METHOD</b>Totally 36 Chinese mini-swine were randomly divided to six groups: the normal control group, the model group, the Shujiangzhi group and TYTZ groups with does of 2.0, 1.0 and 0.5 g x kg(-1), and six each in every group. Except for the normal control group, all of other groups were fed with high-fat diet for 2 weeks. Interventional balloons are adopted to injure their left anterior descending artery endothelium. After the operation, they were fed with high-fat diet for 8 weeks to prepare the coronary atherosclerosis model. In the 8th week after the operation and administration, the intravascular ultrasound was adopted to observe the coronary artery plaque burden of each group and the pathological morphology of coronary artery. Such inflammatory factors as high-sensitivity C-reactive protein (hs-CRP), tumor necrosis factor (TNF)-alpha and interleukin (IL)-6 were detected by ELISA. The expression of NF-kappaB p65 nuclear translocation was observed by the immunohistochemical method.</p><p><b>RESULT</b>Compared with the normal control group, the model group showed significant increase in the coronary artery plaque burden at the end of the experiment (P < 0.01), notably abnormal structural changes in atherosclerotic vascular tissues, luminal stenosis, a large number of foam cells and inflammatory cell infiltration, remarkable growth of hs-CRP, TNF-alpha and IL-6 levels (P < 0.01). The immunohistochemical staining also showed the significant increase in the NF-kappaB p65 nuclear translocation of coronary artery of Chinese mini-swine in the model group. Compared with the model group, TYTZ could significantly attenuate atherosclerotic plaque burden (P < 0.01), inhibit the coronary luminal stenosis, reduce inflammatory cell infiltration, decrease such inflammatory cell factors as hs-CRP, TNF-alpha and IL-6 in serum, and inhibit the NF-kappaB p65 nuclear translocation of coronary artery (P < 0.05 or P < 0.01).</p><p><b>CONCLUSION</b>TYTZ can reduce the downstream inflammatory reaction by controlling NF-kappaB p65 nuclear translocation, so as to inhibit the occurrence and development of coronary atherosclerotic plaque in Chinese mini-swine.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To analyze and summarize changes of syndrome-related biological indices in acute lacuna encephalon infarction patients of upper hyperactivity of Gan yang syndrome (UHGYS), thus providing objective evidence for syndrome typing and disease identification.</p><p><b>METHODS</b>Recruited were 50 patients at Department of Encephalopathy, Xiyuan Hospital, China Academy of Chinese Medical Sciences, who were in line with diagnostic criteria of UHGYS as the experimental group in this study. Another 40 healthy volunteers were recruited as the control group from May 2010 to July 2012. Blood routines (including WBC, RBC, Hb, NEUT%, and LY%), hepatic and renal functions tests (including ALT, AST, TBIL, TP, ALB, Cr, and BUN) were performed by automatic whole blood analyzer and colorimetric technique. The levels of fasting blood glucose, HbAlc, blood lipids (including TC, TG, HDL-C, LDL-C, and VLDL-C), and coagulation functions (including AT-III, PT, PTA, INR, TT, APTT, and FBG, reaction time), renin, angiotensin II, hs-CRP, and Hcy were also measured. The thyroid functions (including FT3, FT4, T3, T4, and TSH) were detected by electrochemiluminescence immunoassay. The levels of tumor necrosis factor alpha (TNF-alpha), IL-6 and IL-1 in serum were measured by ELISA and radioimmunoassay respectively.</p><p><b>RESULTS</b>Compared with the control group, RBC, LY%, ALT, TP, ALB, HDL-C, AT-III activities, contents of PTA and FT4 obviously decreased, TBIL, BUN, Glu, HbAlc, TSH, hs-CRP, renin, Ang II, TNF-alpha, IL-1 and IL-6 significantly increased in the experimental group (P < 0.05, P < 0.01).</p><p><b>CONCLUSION</b>The pathological process of acute lacuna encephalon infarction patients of UHGYS was closely correlated with thyroid functions, the renin-angiotensin-aldosterone system, the extrinsic and intrinsic coagulation systems, as well as inflammation reaction.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study the effect of Sailuotong capsule (Sailuotong) on learning and memory functions of multi-infarct dementia (MID) rats and its mechanism.</p><p><b>METHOD</b>All SD rats were divided into five groups, namely the sham operation group, the model group, the positive group, the low dosage Sailuotong-treated group and the high dosage Sailuotong-treated group. The multi-infarct dementia model was established by injecting the micro-sphere vascular occlusive agent. On the 10th day after the successful operation, the rats were administered intragastrically with distilled water, memantine hydrochloride (20 mg x kg(-1)) and Sailuotong (16.5 mg x kg(-1) and 33.0 mg x kg(-1)) once a day for 60 days respectively, in order to detect the effect of Sailuotong in different doses on the latent period and route length in Morris water maze and the activities of choline acetyltransferase (ChAT) and acetylcholinesterase (AchE) in brain tissues.</p><p><b>RESULT</b>Compared with the sham operation rats, it had been observed that the latent period and route length of MID rats in Morris water maze were significantly increased (P < 0.05 or P < 0.01), and the activity of ChAT in brain tissues was significantly decreased (P < 0.05). After the intervention with Sailuotong for sixty days, the latent period and route length of MID rats in Morris water maze significantly shrank (P < 0.05 or P < 0.01). Additionally, Sailuotong decreased AchE activity, while increasing ChAT activity in brain tissues of MID rats (P < 0.05 or P < 0.01).</p><p><b>CONCLUSION</b>Sailuotong capsule can improve cognitive dysfunction of MID rats to some extent. Its mechanism may be related to its different regulation of activities of ChAT and AchE in brain tissues.</p>
