Effects of moxibustion at bilateral Feishu (BL13) and Xinshu (BL15) combined with benazepril on myocardial cells apoptosis index and apoptosis-related proteins cytochrome c and apoptosis-inducing factor in rats with chronic heart failure.

OBJECTIVE: To observe the effects of moxibustion at bilateral Feishu (BL13) and Xinshu (BL15) combined with benazepril on myocardial cells apoptosis index, the expression levels of apoptosis-related proteins cytochrome c (Cyt-C) and apoptosis-inducing factor (AIF) in chronic heart failure (CHF) rats. METHODS: Sixty-five rats were randomly divided into normal group () and model-I group (). After modeling, CHF rats in model-I group were divided into model group, moxibustion group, benazepril group, moxibustion plus benazepril group (abbreviated as aibei group, the same below), 10 rats in each group. Echocardiogram index was examined by echocardiography. Hemodynamic indices were measured by rat cardiac function meter. Serum B-type brain natriuretic peptide (BNP) was detected by enzyme-linked immunosorbent assay. Myocardial cells apoptosis index was detected by terminal-deoxynucleoitidyl transferase mediated nick end labeling staining. Pathological changes of myocardial tissues were observed by hematoxylin and eosin staining. The expression levels of Cyt-C and AIF in myocardial tissues were detected by Western blot. RESULTS: Compared with normal group, ejection fraction and left ventricular diameter shortening rate in model-Ⅰ group were significantly reduced, myocardial cells of rats in model group exhibited unclear transverse striations, cells swellings and vacuoles, cardiac functions were deteriorated, serum BNP level, myocardial cells apoptosis index, and the expression levels of Cyt-C and AIF were significantly increased. Compared with model group, myocardial cells of rats in moxibustion group, benazepril group, and aibei group were dyed more evenly, muscle fibers were arranged relatively neatly, cardiac functions were improved, serum BNP level, myocardial cells apoptosis index, and the expression levels of Cyt-C and AIF were significantly decreased. Compared with aibei group, cardiac functions were worsened, myocardial cells apoptosis index, and the expression levels of Cyt-C and AIF were increased. CONCLUSION: Moxibustion at bilateral Feishu (BL13) and Xinshu (BL15) combined with benazepril could improve CHF better than moxibustion at bilateral Feishu (BL13) and Xinshu (BL15) or benazepril alone. The mechanisms might be that they can inhibit the expressions of Cyt-C and AIF, and inhibit the apoptosis of cardiomyocytes.

Experimental Research Progress of Replenishing Qi and Activating Blood Circulation Traditional Chinese Medicine on Mitochondrial Quality Control in Treatment of Chronic Heart Failure / 中国实验方剂学杂志

Heart failure is a complex clinical syndrome，which is the final result of compensatory failure of heart injury caused by various reasons. Long-term persistent cardiac stress leads to mitochondrial dysfunction，which in turn further damages cardiomyocytes and leads to disease progression. Timely removal of damaged mitochondria in cardiomyocytes and maintaining a good living environment of viable mitochondria is not only an effective means to protect cardiomyocytes，but also a new way to prevent and treat heart failure and ventricular remodeling. Mitochondrial quality control is a series of cellular activities for mitochondria to maintain their structural and functional stability，including oxidative stress response，regulation of mitochondrial dynamics，mitochondrial autophagy，intracellular calcium regulation and so on. Traditional Chinese medicine（TCM） mostly uses drugs of replenishing Qi and activating blood circulation in the treatment of chronic heart failure，and Qi and mitochondria are similar in function. According to TCM，the performance of the body as "static，descending and inhibitory" in the case of Qi deficiency can also be compared with the energy defect of mitochondria. The classical method of tonifying qi and activating blood circulation in TCM can be applied here. In recent years，TCM takes mitochondria as the target and carries out many related experimental studies from the point of view of myocardial energy supply. It is found that Chinese herbs for replenishing Qi and activating blood circulation can participate in regulating the quality control mechanism of intracellular mitochondria with multiple targets and links. It is proved by experiments that Chinese herbs for replenishing Qi and activating blood circulation can exert myocardial protective effect through this mechanism.

Study on characteristics and data mining of 464 cases of lung diseases in Xin'an Wang's medicine / 中国中药杂志

The purpose of this paper is to study the use rules of drugs for lung diseases in internal medicine department of Xin'an Wang's family, discuss the compatibility of common drugs for lung diseases, guide clinical application, and inherit Xin'an medicine. By retrospective study on lung diseases cases in Wang's internal medicine works, the lung diseases and use frequency of common drugs treated by Wang's medicine were counted, and the systematic clustering and association rule analysis of common drugs were conducted by using SPSS Statistic 20 and SPSS Modeler 18.0, respectively. The results showed that asthma, cold and cough were the main lung diseases treated by Wang's medicine, and the commonly used medicines included antitussive and antiasthmatic drugs, spleen-invigorating and dampness-removing drugs, and expectorants. The medicine taste was mainly bitter, pungent and sweet, with cold and warm properties in a balanced way, without severely cold or hot herbs, mainly attributing to the lung and stomach meridians. In clustering analysis, 10 drug combinations were obtained; association analysis showed that two, three, four association rules respectively had 11, 21, and 10 groups, and each drug group had 11, 16, and 5 items. Core combinations: Poria, Armeniacae Semen Amarum, Asteris Radix et Rhizome, Coicis Semen, Farfarae Flos, Dendrobii Caulis, Perilla Frutescens, Stemonae Radix, Citri Reticulatae Pericarpium, Cynanchi Stauntonii Rhizome et Radix, Meretricis Concha Cyclinae Concha, Belamcandae Rhizoma, and Pinelliae Rhizome. Xin'an Wang's medicine paid attention to the lung nature when treating lung diseases. Lung is a delicate organ, not resistant to coldness or heat, so severely cold or hot herbs shall not be used, and the clear and light drugs with functions of dispersing lung Qi, clearing phlegm evil, strengthening spleen, eliminating phlegm, and relieving cough and asthma are often used. Lung deficiency is a kind of deficiency of Qi and Yin, so both Qi and Yin shall be regulated. Deficiency of Yin would burn the lung and make the lung collaterals blocked. In this case, the lung collaterals shall be dredged for hemostasis. Long time of lung deficiency would hinder the distribution of body fluid, and lung shall be regulated to dissipate phlegm.

AduoLa Fuzhenglin down-regulates microwave-induced expression of β1-adrenergic receptor and muscarinic type 2 acetylcholine receptor in myocardial cells of rats / 生物医学与环境科学（英文）

This paper is aimed to study the effect of ADL on expression of β1-AR and M2-AchR in myocardial cells of rats exposed to microwave radiation. Immunohistochemistry, Western blot and image analysis were used to detect the expression of β1-AR and M2-AchR in myocardial cells at 7 and 14 d after microwave exposure. The results show that the expression level was higher in microwave exposure group and 0.75 g/(kg•d) ADL group than in sham operation group and significantly lower in 1.5 and 3.0 g/(kg•d) ADL groups than in microwave group. So we have a conclusion that the expression of β1-AR and M2-AchR is down-regulated in myocardial cells of rats exposed to microwave radiation. ADL can protect rats against microwave-induced heart tissue injury.

[Effect of tagalsin on p53 and Bcl-2 expression in hepatoma H(22) tumor-bearing mice].

OBJECTIVE: To explore the effect and mechanism of tagalsin on hepatoma cells. METHODS: The animal models were established by transplanting H(22) mouse hepatoma cells to mouse liver, and ten days later the mice were randomly divided into five groups: blank group, carmofur positive group and tagalsin groups, including low-dose, middle-dose and high-dose groups. Then medicine or oil was given to the mice by gastric gavage in consecutive 5 days with a 2-days interval as a course of treatment, two courses in all. All mice were killed at 24 hours after medication, and the survival period, ascites conditions, aggressive conditions intra- or extra-liver, weight changes, tumor volume and spleen index of the tumor-bearing mice were observed. Pathological changes of the tumors were examined. Apoptotic factors p53 and Bcl-2 protien and mRNA were detected by immunohistochemistry and reverse transcription polymerase chain reaction (RT-PCR). RESULTS: tagalsin inhibited the hepatoma growth effectively without influencing spleen index to some extent. The tumor inhibition rate of tagalsin low, middle and high dose groups were 17.9%, 63.1% and 71.8%, respectively. Immunohistochemical results showed that the p53 and Bcl-2 protein positive cell counts of the positive control and experimental groups were significantly lower than those of the blank group (P < 0.01). RT-PCR results showed that the p53 mRNA expression was significantly enhanced and Bcl-2 mRNA expression was decreased in the positive control groups and tagalsin treatment groups, especially in the high dose group, compared with those of the blank group (P < 0.05). CONCLUSIONS: tagalsin can inhibit the growth of mouse hepatoma cells significantly. The mechanism of its anti-tumor effect may work via up-regulating the wild type p53 gene expression and down-regulating Bcl-2 gene expression and thus regulating tumor cell apoptosis.
