OBJECTIVETo establish the "clinical-mimetic" Chinese medicine symptom complex score method for the coronary heart disease Chinese miniature swine model with phlegm-stasis cementation syndrome, in order to observe the effect of formula of removing both phlegm and blood stasis (TYTZ) on the Chinese medicine symptom complex score for the coronary heart disease Chinese miniature swine model with phlegm-stasis cementation syndrome.

METHODTotally 36 Chinese miniature swine were randomly divided to the normal control group, the model group, the Shujiangzhi group, and TYTZ groups with doses of 2.0, 1.0 and 0.5 g x kg(-1), with six in each group. Except for the normal control group, all of the other groups were fed with high fat diet for two weeks. The coronary heart disease model with phlegm-stasis cementation syndrome was established by injuring left anterior descending artery with interventional balloons and continuously feeding with high fat diet for eight weeks. After the operation, the groups were administered with drugs for eight weeks. Their main symptoms, accompanied symptoms, tongue and pulse signs of the coronary heart disease Chinese miniature swine with phlengm-stasis cementation syndrome were observed according to the symptom-graded scoring method.

RESULTCompared with the model group, TYTZ in different doses could reduce the scores of main symptoms at the 6th and 10th week. Specifically, TYTZ in low dose could reduce the scores of tongue at the 6th week and the scores of accompanied symptoms, and tongue and pulse signs at the 10th week; And TYTZ in high dose could decrease all symptom scores at the 6th and 10th week (P < 0.05 or P < 0.01).

CONCLUSIONTYTZ can improve the scores of the main symptoms, accompanied symptoms, tongue and pulse signs in coronary heart disease Chinese miniature swine with phlegm-stasis cementation syndrome. It is suggested that the "clinical-mimetic" objective scoring for syndromes of Chinese miniature swine is of great significant to the development of new traditional Chinese medicine drugs.

OBJECTIVETo discuss that pathogenesis evolvement regularity of Chinese miniature swine with phlege-stasis cementation syndrome of coronary heart disease.

METHODEighteen Chinese miniature swine were randomly divided to the normal control group, the model group and the Danlou tablet group, with six swine in each group. Except for the normal control group, all of the other groups were fed with high fat diet for two weeks. The coronary heart disease model with phlegm-stasis cementation syndrome was established by injuring left anterior descending artery with interventional balloons and continuously feeding with high fat diet for eight weeks. The levels of BMI, hemorheological parameters, lipids in serum and inflammatory cytokines were observed at the 0th (before the experiment), 2nd (before operation or drug administration), 6th (four weeks after drug administration) and 10th week (eight weeks after drug administration) of study. The levels of TG and TC in liver and the pathological changes in coronary artery tissues were also observed at the end of study.

RESULTCompared with the normal control group, the model group had showed significant increase in the levels of TC, TG, LDL-C and VLDL-C in serum (P < 0.01) from the second week to the end of the experiment, with notable rise in the whole blood viscosity under the shear rates of 5 s(-1) and 60 s(-1). At the 6th week, the levels of BMI and TG and TNF-alpha in serum significantly increased. At the 10th week, the levels of BMI and hs-CRP, IL-6 and TNF-alpha in serum significantly increased as well, with remarkable increase in coronary stenosis, intimal thickness and the ratio between intimal thickness and media thickness (P < 0.05 and P < 0.01), and significant rise in TC and TG in livers (P < 0.01). Compared with the model group, the Danlou tablet group showed obvious reduction in severity of coronary artery lesion, intimal thickness and lumen stenosis ratio and ratio between intimal thickness and media thickness (P < 0.01), BMI, TC, TG, LDL-C and VLDL-C in serum, TC and TG in liver, as well as hs-CRP, IL-6 and TNF-alpha levels in serum (P < 0.05 and P < 0.01), with notable decline in the whole blood viscosity under the shear rates of 5 s(-1) and 60 s(-1).

CONCLUSIONThe interaction of phlegm, blood stasis and toxin syndromes helps promote the progress and development of AS plaques, which is the key pathogenesis of phlegm-stasis cementation syndrome in coronary heart disease.

Objective To investigate the effect of norcantharidin on growth inhibition and induction of apoptosis of human rectal cancer Colo 320 cells. Methods Norcantharidin (NCTD) in different concentrations were added to rectal cancer Colo 320 cells. Morphological characteristics of apoptosis were observed using the light microscope and transmission electron microscope. The expressions of Bag-1 and Bcl-2 proteins were tested by Western blotting. The growth inhibition of Colo 320 cells on the cell cycle was observed by flow cytometry. Results The apoptosis morphological changes of Colo 320 cells were observed by the light microscope and transmission electron microscopy. Flow cytometry analysis showed that the cell count of G2/M phase in experimental group was higher than that in control group ( <0.05) but the cell counts of G0/G1 and S phases have decreased in experimental group after treatment with NCTD at the concentrations of 5μg/mL, 10μg/mL and 20 μg/mL, and presented dosage dependence relations. The expressions of Bag-1 and Bcl-2 proteins have decreased. Conclusion Norcantharidin has inhibitory effect on rectal cancer Colo 320 cells, and the effect may be related to the cell cycle arrest and apoptosis.

OBJECTIVETo comparatively analyse the objective characteristics of different syndrome types of qi-disturbance-induced blood stasis syndrome (QDBS) in the pathogenetic evolution of unstable angina coronary heart disease (UA-CHD).

METHODSSeventy-eight patients with UA-CHD of QDBS were differentiated into 2 groups: 55 in the qi-deficiency-induced blood-stasis syndrome group (A) and 23 in the qi-stagnation-induced blood-stasis syndrome group (B). The comparative analysis on them was carried out through comparing their blood pressure, glucose and lipid metabolisms, coagulation function, thyroid function and inflammation reaction changes, etc.

RESULTSIn the pathogenetic process of qi-disturbance induced blood stasis, the initiating age, levels of HbA1c, TSH, PT and APTT between the two groups were significantly different (P < 0.05). Levels of TNF-alpha and LN were higher and levels of sIgA lower in patients than those in healthy subjects (P < 0.05).

CONCLUSIONSInflammation immune reaction may play an important role in the pathogenetic process of blood-stasis syndrome, and the functional disturbance of hypothalamus, pituitary and endocrinal secretion induced by emotional stress is possibly the essence of qi-stagnation induced blood stasis syndrome.

The objective of the present study was to establish a method based on principal component analysis (PCA) for the study of transdermal delivery of Chinese medicinal formulae, and to choose the best penetration enhancers for Qingfei Xiaocuo gel depend on this method. Using improved Franz type diffusion cell and excised rat skin in vitro as transdermal barrier, the receptive solution fingerprint was established by HPLC, harvesting the areas of the common peaks in the fingerprint, then the total factor scores of the concentrations at different times were calculated using PCA and were employed instead of the concentrations to compute the cumulative amounts (Q12) and enhancement ratio (ER), the latter of which were considered as the indexes for optimizing penetration enhancers. Compare to the control group, the ER of the other groups increased significantly and furthermore, 2.5% azone with 2.5% menthol manifested the best effect. PCA represent most information in the receptive solution, the method above could choose the best penetration enhancers, it could be a reference for the study of transdermal delivery of Chinese medicinal formulae.

Objective To observe any effect of low intensity pulsed ultrasound (LIPUS) on the expression of integrin-focal adhesion kinase (FAK)-mitogen-activated protein kinase (MAPK) mechanochemical transduction pathway-related proteins in the chondrocytes of rabbits with knee osteoarthritis (OA).Methods Of the 18 New Zealand white rabbits selected for the study,twelve received knee anterior cruciate ligament transection to model OA.The remaining 6 rabbits served as normal controls.At the 4th week after modeling the rabbits were sacrificed and chondrocytes were isolated and cultured in vitro.All the cultured cells were randomly divided into three groups:a normal control group (NC),an OA model group (OA) and an OA model plus LIPUS group (OA + LIPUS).When the cells had been cultured to the 2nd passage,the NC group and OA group cells had received no treatment.The OA + LIPUS group cells were exposed to 40 mW/cm2 of LIPUS for 20 min,once a day for 6 days.The expression of collagen protein type Ⅱ,aggrecan,MMP-13,integrin β1 p-FAK and p-p38,p-ERK1/2 and p-JNK Mapks were detected by Western blotting.Results Compared with the NC group,the expression of collagen type Ⅱ and aggrecan was significantly lower in the OA and OA + LIPUS groups,with more significantly lower expression of collagen type Ⅱ and aggrecan in the OA group than in the OA + LIPUS group.Compared with the NC group,the expression of MMP-13 was significantly higher in the OA and OA + LIPUS groups,with a significantly larger increase in the OA group.Compared with the NC group,the expression of integrin β1 and p-FAK was also significantly higher in the OA and OA + LIPUS groups,with a significantly larger increase in the OA + LIPUS group.Compared with the NC group,the expression of p-p38,p-ERK1/2 and p-JNK was also significantly higher in the OA group,but compared with the OA group,the expression of those kinases was,on average,significantly lower in the OA + LIPUS group.Conclusions LIPUS can inhibit the degradation of collagen type Ⅱ and aggrecan,and inhibit the expression of MMP-13,p-p38,p-ERK1/2 and p-JNK in OA chondrocytes,at least in vitro.At the same time,LIPUS can increase the expression of integrin β1 and p-FAK.The results show that LIPUS may activate an integrin-FAK-MAPK mechanochemical transduction pathway to induce changes in the extracellular matrix of chondrocytes.

ObjectiveTo retrospectively analyze clinical data of patients who has left-side valvular disease combined with severe tricuspid regurgitation and evaluate the effect of our modified tricuspid annuloplasty with enforcement of artificial felt strip.Methods76 patients who had left-side valvular disease combined with severe tricuspid regurgitation received operations between Jan.2008 and Jun.2010.The average age of the patients was 53.5 years old (32 male and 44 female).Besides the severe tricuspid regurgitation, other combined cardiac impairments included mitral valvar disease (52 cases), aortic valvar disease(5 cases), double valvar disease(19 cases) and left atrial thrombosis(22 cases).6 patients had grade II cardiac function according to the NYHA criteria, while 47 and 23 were in grade III and IV, respectively.Other signs included cyanosis(5cases), jaundice(11 cases), neck vein engorgement(48 cases) , ascites(22 cases), hepatomegaly(41 cases) and pitting edema in the lower limbs(68 cases).The concomitant operative procedures included mitral valve replacement in 52 patients,aortic valve replacement in 5 patients, double valve replacement in 19 patients, removal of left atrial thrombus in 22 patients,left atrium folding in 21 patients and left atrium appendage suture in 68 patients.Left-sided valve disease were corrected first,TAP was performed on the beating heart after the heart had been defibrillated.The anteroseptal commissure was plicated first.A double-armed 3-0 pledgeted suture was taken through the base of the septal leaflet, 5-6 mm from the commissure, extending along the annulus, and out from the point in the anterior annulus 10-12 mm from the anteroseptal commissure.Both ends of the suture was tied until the two Teflon pledgets approximated each other near the commissure.Then a semicircular De Vega type of plicating with a 3-0 prolene was taken, starting just from the anterior annulus near the anteroposterior commissure, and extending clockwise to a point just cephalad to the posteroseptal commissure.The suture was tied with positioning a 27-29 mm valve siser across the tricuspid valve.At last, a 3-5 mm width felt strip was prepared and was sutured to the plicated posterior annulus region with interrupted mattress sutures of 2 to 3 2-0 prolene.A favorable result was considered when TR was not marked by saline injection.Echocardiography was routinely examined one week postoperatively and patients were followed up 6 month after discharge.ResultsThere is no death in all patients.The CVP diminished significantly from 16mmHg preoperatively to 8mmHg postoperatively (P = 0.0021).The systomic pulmonary pressure diminished from 59 mmHg preoperatively to 41 mmHg postoperatively (P = 0.038).Echo one week postoperative showed no tricuspid regurgitation in 56 patients and mild in 18 patients, while 2 had moderate tricuspid regurgitation.The diameter of right atrium diminished significantly postoperatively, too.The ejection fraction was improved even though there was not significant difference as compared with preoperative data.The cardiac function of all patients improved and the signs of right heart failure were alleviated or disappeared.Follow up 1 to 36 months showed no change of the regurgitation except for one become moderate from mild when discharged.No hepatic congestion or edema was observed in all patients.ConclusionThese new modifications make the technique more selective in the remodeling of the tricuspid annulus.It could achieve better coaptation of the anterior leaflet with the others, successful annular reduction, better maintenance of the contractile property of the tricuspid ring, better distribution of pursing force in the more dilated region.It could prevent the tear of the endocardium in the posteroseptal region in the long period of time postoperatively.
