The Book of Changes is known as a famous ancient book in China. In the chapter on Copula of this masterpiece the relations among the changes of heaven and earth, movement and stillness, and Qian and Qun have been revealed through adopting "YiXing" and "LiYi", two varieties of schools of Yi (Change). This paper sets out to compare the depiction of Yin and Yang, movement and stillness recorded in the book of the Yellow Emperor's Classic of Medicine with the notions mentioned above. It is also our attempt to discover the same intrinsic principle existed in both Chinese ancient philosophy and Chinese ancient medicine.

OBJECTIVE: To investigate the effect of Xuebijing injection on the cardiac function and calcium ions of cardiocyte in rats after anoxia-induced cardiac arrest-cardiopulmonary resuscitation(CA-CPR).METHODS: CA-CPR model was induced in rats and then the model rats were randomized to 4 groups,i.e.sham group,model group,Xuebijing injection high dose group(4 mL?kg-1),and Xuebijing injection lowdose group(Xuebijing injection 2 mL?kg-1).Mean arterial pressure(MAP),?LVdp/dt max,average fluorescence intensity of calcium and pathological changes of cardiocytes were observed at 0 and 6 hours after resuscitation,respectively.RESULTS: Compared with model group,Xuebijing ingection high dose group at 6 h showed significantly increased MAP(P

Objective To study the inhibition of berberine on organ anion transporters (OATs) and its bidirectional trans-membrane transport.Method The transgene cell lines of the organ anion transporters including OAT1,OAT2,OAT3,OAT4,OAT7,and URAT1 were constructed and selected by animal cell transgenic method mediated by transporter Lipo 3000.Wild type (WT) cells were used as control group,and activity of OATs was verified by adding their radiolabeled substrates and inhibitors.The inhibition of 100 μmol/L berberine on the transporters was investigated in vitro.The IC50 of berberine on URAT1 was also determined.The bidirectional transport of berberine was studied through the Caco-2 model.Result The results showed that 100 μmol/L berberine inhibited the activity of OAT1,OAT2,OAT3,OAT4,OAT7 and URAT1 to (70.48±4.23)％,(69.13±1.28)％,(72.12±3.28)％,(79.77±6.49)％,(69.51 ±5.99)％ and (38.4 ± 2.67)％ respectively,the IC50 of berberine to URAT 1 was 13.19 μmol/L,the Papp (A-B) of 50 μmol/L and 100 μmol/L berberine were separately 0.28 × 10-6 and 0.40 × 10-6 cm/s,and the effiux rates were separately 3.18 and 3.15.Conclusion Berberine shows a stronger inhibition to URAT1 compared to OAT1,OAT2,OAT3,OAT4 and OAT7.Berberine may be the substrate of some effiux transporters.This study provides theoretical basis for explaining the low bioavailability ofberberine and forecasting the possible drug-drug interaction.

Objective To study the protective effect of erythropoietin (EPO) on brain tissue with cardiac arrest-cardiopulmonary resuscitation (CA-CPR) and its mechanism.Methods 120 male Sprague-Dawley (SD) rats were randomly divided into three groups (each n =40),namely:sham group,routine chest compression group,and conventional chest compression + EPO group (EPO group).The rats in each group were subdivided into CA and 6,12,24,48 hours after restoration of spontaneous circulation (ROSC) five subgroups (each n =8).The model of CA was reproduced according to the Hendrickx classical asphyxia method followed by routine chest compression,and the rats in sham group only underwent anesthesia,tracheostomy intubation and venous-puncture without asphyxia and CPR.The rats in EPO group were given the routine chest compression + EPO 5 kU/kg (2 mL/kg) after CA.Blood sample was collected at different time points of intervention for the determination the content of serum S100 β protein by enzyme linked immunosorbent assay (ELISA).All the rats were sacrificed at the corresponding time points,and the hippocampus was harvested for the calculation of the number of S100 β protein positive cells,and to examine the pathological changes and their scores at 24 hours after ROSC by light microscopy.Results With prolongation of ROSC time,the serum levels of S100 β protein (μg/L) in the routine chose compression group and the EPO group were significantly elevated,peaking at 24 hours (compared with CA:305.7 ± 29.2 vs.44.4 ± 6.2 in routine chest compression group,and 276.7±28.9 vs.44.7±5.6 in the EPO group,both P ＜ 0.05),followed by a fall.The levels of S100β protein at each time point after ROSC in EPO group were significanthy lower than those of the routine chest compression group (83.2 ± 7.5 vs.114.3 ± 15.3 at 6 hours,123.9 ± 20.2 vs.184.9 ± 22.2 at 12 hours,276.7 ± 28.9 vs.305.7 ± 29.2 at 24 hours,256.3 ± 26.6 vs.283.2 ± 23.6 at 48 hours,all P ＜ 0.05).With the prolongation of ROSC time,the S100 β protein positive cell number in brain (cells/HP) in the routine chest compression group and the EPO group was significantly increased,peaking at 24 hours (compared with CA:14.3±2.2 vs.6.7±0.7 in the routine chest compression group,11.3± 1.3 vs.6.8±0.9 in the EPO group,both P ＜ 0.05),then it began to fall.The S100 β protein positive cell number in brain at each time point after ROSC in the EPO group was significantly lower than that of the routine chest compression group (7.0±0.9 vs.7.9± 1.9 at6 hours,8.4± 1.1 vs.10.2±2.2 at 12 hours,11.3± 1.3 vs.14.3±2.2 at24 hours,8.3±0.8 vs.10.8±2.0 at48 hours,all P ＜ 0.05).Under the light microscope,a serious brain cortex injury was found after reproduction of the model,and the degree of injury was reduced after EPO intervention.The pathological score at 24 hours after ROSC in EPO group was lower than that of routine chest compression group (3.83±0.73 vs.4.17±0.75,P ＜ 0.05).Conclusions The S100β protein level in serum and brain tissue was increased early in asphyxia CA-CPR rats.EPO intervention can reduce the expression of S100 protein and reduce the degree of brain injury.

Objective To study the regulation of aquaporin-1(AQP-1)changes in the heart of septic rats, compare the correlations of the AQP-1 with myocardial cytokines tumor necrosis factor-α(TNF-α),interleukin-6 (IL-6),and myocardial tissue water content,and to investigate the dexmedetomidine protective effect on myocardia in septic rats and its possible mechanism. Methods According to the random number table methods,90 male Sprague-Dawley(SD)rats were divided into sham operation group,sepsis model group and dexmedetomidine group, 30 rats in each group. The rat sepsis model was established by cecal ligation and puncture(CLP). In the sham operation group,the animal abdomen was only opened and closed without CLP. Half hour before operation in dexmedetomidine group,dexmedetomidine 1μg/kg(2μg/mL)was injected into the vein,while in the model and sham groups,saline 5 mL/kg was subcutaneously injected into the rat after the operation. At 2,12,24,48,72 hours after operation,6 rats were sacrificed and their hearts removed at one time point in a group. Enzyme linked immunosorbent assay(ELISA)was used to detect the content of AQP-1 and the levels of the TNF-α,IL-6 in the myocardial tissue homogenate at all time points,the myocardial tissue water content was detected by dry wet weight,and the correlations between AQP-1 and TNF-α,IL-6 and between AQP-1 and myocardial tissue water content were compared. Results From 2 hours after operation,the levels of the AQP-1,TNF-αand IL-6 in model group were significantly higher than those in the sham operation group;with prolongation of time,the level of AQP-1 and myocardial tissue water content were decreased, but the levels of TNF-α and IL-6 were persistently increased. From 2 hours after operation in dexmedetomidine group,all the above indexes except myocardial tissue water content at 72 hours after operation were significantly lower than those in the model group〔AQP-1(ng/g):9.29±0.15 vs. 9.73±0.26,TNF-α(pg/g):109.47±8.41 vs. 128.13±7.36,IL-6(pg/g):232.95±20.56 vs. 279.71±22.24,myocardial tissue water content:(74.82±6.37)%vs.(75.62±6.39)%,all P<0.05〕,but still higher than those of the sham operation group. The correlation analyses for the septic group showed that the change of AQP-1 was positively correlated to the myocardial water content in early stage(r=0.418,P=0.001)and later stage(r=0.235,P=0.022),and the changes of the AQP-1 in early stage (at post-operative 2 hours)were positively correlated to the concentration changes of the cytokines TNF-α(r=0.235,P=0.021)and IL-6(r=0.345,P=0.003),but in the later stage(at post-operative 72 hours)were negatively correlated with the changes of TNF-α(r=-0.408,P=0.037)and IL-6(r=-0.276,P=0.002). Conclusions In the early stage of septic rats,there is obvious myocardial injury,resulting in the over expression of AQP-1 and the occurrence of myocardial edema,dexmedetomidine can play a role in myocardial protection in such rats and its mechanism is possibly related to the reduction of the expression of AQP-1 and the levels of inflammatory cytokines, and in turn the alleviation of myocardial cell edema.

Objective To observe the glucose utilization in adipose tissue and skeletal muscle during catch-up growth, and to explore the mechanism of catch-up growth of adipose tissue. Methods Male Wistar rats were randomly divide into normal control group(NC)and catch-up group(RN). Rats in RN group received 50%of food consumed by NC group for 4 weeks, then were re-fed spontaneously as the rats in NC group. In the end of the fifth week(NC1 group and RN1 group)and the sixth week(NC2 group and RN2 group), the experiment was performed. [3]-2-deoxy-glucose was used for detecting the glucose uptake rate. RT-PCR and Western-blot were used for detecting the levels of mRNA and membrane protein of glucose transporter-4(Glut4). Results The glucose uptake rates in adipose tissue and skeletal muscle of RN1 group increased by 189.6%(P<0.01)and reduced by 36.5%(P<0.05)respectively, as compared with NC1 group. After 2 weeks of catch-up growth, the glucose uptake rates in adipose tissue of RN2 group increased by 157.3%(P<0.01)and decreased by 41.5%(P<0.05) in skeletal muscle as compared with NC2 group. However. no significant difference in Glut4 mRNA levels in muscle or in adipose tissue between NC and RN groups were found. The membrane protein of GIut4 after insulin-stimulating in RN1 group and RN2 group reduced by about 46.5%(P<0.01)and 32.1%(P<0.05)in muscle and increased by 116.5%(P<0.01)and 89.9%(P<0.01)in adipose tissue respectively. Conclusion There exists the redistribution of glucose from skeletal muscle to adipose tissue during the early stage of catch-up growth, which results in the catch-up growth of adipose tissue. This change is induced by the tissue-specific alteration of insulin-stimulated Glut4 protein translocation.
