OBJECTIVETo study the correlation between various complications of chronic heart failure (CHF) patients and Chinese medical syndromes, thus indicating distribution laws of Chinese medical syndromes in various complications of CHF patients.
METHODSChinese medical syndrome typing was performed in 630 CHF patients by cross-sectional study of the demographic data, history of present diseases, related information on Chinese medical four diagnostic methods, and the distribution of complications. Logistic regression analysis was used to determine the correlation of various complications of CHF patients and Chinese medical syndromes.
RESULTSIn this study, recruited were common complications such as hypertension, diabetes, arrhythmia, hyperlipemia, and cerebral vascular accident, and so on. Main syndromes were sequenced as qi deficiency syndrome, blood stasis syndrome, water retention syndrome, yin deficiency syndrome, phlegm turbid syndrome, yang deficiency syndrome. Results of Logistic regression analysis indicated that correlation existed between common complications and Chinese medical syndromes. In CHF complicated hypertension patients, Logistic regression analysis showed qi deficiency syndrome and yang deficiency syndrome were negatively correlated with hypertension (P < 0.05). In CHF complicated diabetes patients, Logistic regression analysis showed phlegm turbid syndrome and water retention syndrome were positively correlated with diabetes (P < 0.05). In CHF complicated arrhythmia patients, there was no statistical difference in the distribution of each syndrome (P > 0.05). In CHF complicated hyperlipemia patients, Logistic regression analysis showed qi deficiency syndrome and water retention syndrome were negatively correlated with hyperlipemia (P < 0.05), while blood stasis syndrome, yin deficiency syndrome, and phlegm turbid syndrome were positively correlated with hyperlipemia (P < 0.01). In CHF complicated cerebral vascular accident patients, Logistic regression analysis showed qi deficiency syndrome and yang deficiency syndrome were negatively correlated with cerebral vascular accident (P < 0.01, P < 0.05).
CONCLUSIONSThere existed certain correlations between complications of CHF and the distribution of main Chinese medical syndromes. It could be used as guidance for treating CHF and its various complications by Chinese medicine and pharmacy.

Objective To explore the effects of acupuncture on pruritic behaviors, expression of 5-HT neurons in medulla oblongata and 5-HTR2B on mice with chloroquine-induced pruritus; To discuss the mechanism of action of acupuncture in chloroquine-induced pruritus. Methods A non-histamine-dependent pruritus model was prepared by subcutaneous injection of chloroquine into the back of the neck. Forty C57B/6J mice were randomly divided into model-acupuncture group, model-non-acupuncture group, normal saline group and blank control group, with 10 mice in each group. After modeling, acupuncture was given in Xuehai, Quchi and Hegu on both sides. The plug and twist way was used to stimulate, once a day, three times. Model-non-acupuncture group received no acupuncture. Normal saline group received the neck injection of saline in the back. Blank control group received no treatment. Behavioral changes were observed, and immunofluorescence technique and Western blot were used to test the expression of 5-HT neurons and 5-HTR2B in medulla oblongata neurons. Results The number of scratches in model-acupuncture group and model-non-acupuncture group was obviously more than normal saline group and blank control group (P<0.05). The number of scratches in model-acupuncture group was lower than that of model-non-acupuncture group (P<0.05). The expression of 5-HT in medulla oblongata neurons was unclear in both normal saline group and blank control group. The expression of 5-HT neurons in medulla oblongata significantly increased in model group, which decreased after acupuncture. The expression of 5-HTR2B of model group was significant higher than normal saline group and blank control group (P<0.01). Compared with model-non-acupuncture group, the expression of 5-HTR2B in model-acupuncture group significant decreased (P<0.01). Conclusion Acupuncture can significantly inhibitscratching behaviors in mice induced by chloroquine, and the mechanism may be realized by decreasing the expression of 5-HT neurons and 5-HTR2B in medulla oblongata neurons.

PURPOSE: Although the interferon α (IFNα) signaling and the paired-like homeodomain transcription factor 2 (PITX2) have both been implicated in the progression of breast cancer (BCa), it remains obscure whether these two pathways act in a coordinated manner. We therefore aimed to elucidate the expression and function of PITX2 during the pathogenesis of endocrine resistance in BCa. MATERIALS AND METHODS: PITX2 expression was assessed in BCa tissues using quantitative reverse transcription polymerase chain reaction (RT-qPCR) and immunohistochemistry and in experimentally induced letrozole-resistant BCa cells using RT-qPCR and immunoblotting. Effects of PITX2 deregulation on BCa progression was determined by assessing MTT, apoptosis and xenograft model. Finally, using multiple assays, the transcriptional regulation of interferon-inducible transmembrane protein 1 (IFITM1) by PITX2 was studied at both molecular and functional levels. RESULTS: PITX2 expression was induced in letrozole-resistant BCa tissues and cells, and PITX2 induction by IFNα signaling powerfully protected BCa cells against letrozole insult and potentiated letrozole-resistance. Mechanistically, PITX2 enhanced IFNα-induced AKT activation by transactivating the transcription of IFITM1, thus rendering BCa cells unresponsive to letrozoleelicited cell death. Additionally, ablation of IFITM1 expression using siRNA substantially abolished IFNα-elicited AKT phosphorylation, even in the presence of PITX2 overexpression, thus sensitizing BCa cells to letrozole treatment. CONCLUSION: These results demonstrate that constitutive upregulation of PITX2/IFITM1 cascade is an intrinsic adaptive mechanism during the pathogenesis of letrozole-resistance, and modulation of PITX2/IFITM1 level using different genetic and pharmacological means would thus have a novel therapeutic potential against letrozole resistance in BCa.

OBJECTIVETo evaluate the roles of enteric nervous system neurotransmitters, nitric oxide (NO), substance P (SP) and vasoactive intestinal polypeptide (VIP), and interstitial cells of Cajal (ICC) in the colon in slow transit constipation in rats.
METHODSThirty-two healthy Wistar rats were randomly assigned to control and constipated groups. In the constipated group, the rats were daily administered with diphenoxylate (8 mg/kg) to develop slow transit constipation, while the control rats were fed with water. The number and the weight of fecal granule and the body weight of rats were recorded every 5 days for 90 days. Transit functions of intestinal movement were examined by an activated charcoal suspension pushing test one week after stopping the administration of diphenoxylate. The levels of NO and SP in the colonic mucosa were measured by nitrate reductase methods and ELISA respectively. The distribution of VIP and ICC positive cells confirmed with symbolic c-kit+ cells in the colonic wall were observed by immunohistochemical methods.
RESULTSThe daily number of fecal granule in the constipated group was significantly less than that in the control group (P<0.01). The mean weight of each fecal granule in the constipated group was significantly higher than that in the control group (P<0.01). The discharge time of the first granule of black faeces in the constipated group (430.2+/- 132.1 min) was significantly longer than that in the control group (337.2+/- 74.7 min; P<0.05). There were no significant differences in NO and SP levels and the density of VIP positive cells in the distal colonic segment between the two groups. The number of c-kit+ cells in the distal colonic wall in the constipated group was significantly reduced compared with that in the control group (P<0.05).
CONCLUSIONSThe reduction of ICC number in the distal colon may be contributed to the pathogenesis of slow transit constipation in rats.
