Research on post-marketing Chinese medicine should be the systematic study from application to mechanism. Clinical evaluation is the basis of mechanism study, we can find the clue from clinical evaluation, then make a mechanism study to find the reason, then apply the results to clinic. So it is a virtuous circle. In order to achieve it, we cannot be limited to traditional Chinese medicine, we should form multi-disciplinary team under the direction of grand science thinking, try hard to put industry-university-research institute collaboration association to use, and if necessary, explore the new model of the whole nation system. An appropriate operation mechanism is very important.

OBJECTIVETo explore the effect of Danlou Tablet (DT) on arrhythmia model rats induced by transient myocardial ischemia/reperfusion (I/R).

METHODSTotally 45 healthy Wistar rats were randomly divided into 3 groups, the sham-operation group, the model group, and the DT group, 15 in each group. Rats in the sham-operation group and the model group were administered with distilled water by gastrogavage at the daily dose of 0.1 mL/kg. Rats in the DT group was administered with 0.53 g/mL DT suspension by gastrogavage at the daily dose of 0.1 mL/kg. All medication was lasted for 10 successive days. The myocardial I/R experiment was performed at 1 h after the last gastrogavage. ECG was performed before ligation and at I/R. The jugular arterial blood pressure of all rats was measured during the whole course. ST segment changes were observed at each time point of I/R. The ventricular fibrillation, the premature ventricular, the number and the duration of ventricular tachycardia within 30 min reperfusion were also observed. Activities of Na(+)-K+ ATPase and Ca2+ ATPase in the myocardium homogenate were detected as well.

RESULTSThe jugular arterial blood pressure and the heart rate were slightly lower in the DT group than in the model group, but with no statistical difference (P > 0.05). Compared with the sham-operation group, the degree of ST segment was obviously elevated in the model group at 0, 5, and 7 min (P < 0.05). It was significantly lower in the DT group than in the model group (P < 0.01). ST seg ment was more elevated at 5 min than at 0 min in the model group, but the degree of ST segment elevation was still obviously lower in the DT group than in the model group (P < 0.05). There was no statistical difference in the degree of ST segment elevation at 7 min between the two groups (P > 0.05). At 0 min when the decrement of ST segment exceeded one half the ischemia, there was no statistical difference in the degree of myocardial ischemia between the model group and the DT group (P > 0.05). Compared with the model group, the incidence of fatal and nonfatal ventricular fibrillation, the frequency and duration of ventricular tachycardia and premature ventricular beats were obviously lessened, and activities of Na(+)-K+ ATPase and Ca(2+)-ATPase increased (all P < 0.05).

CONCLUSIONSDT could significantly protect arrhythmias induced by transient I/R. Its effect might be related to lowering the degree of myocardial ischemia, and increasing ion transport channel related enzyme activities.

Background: Dampness-heat syndrome is a major syndrome type in patients with a sharp deterioration of chronic renal failure (CRF). Qingshen Decoction, a compound traditional Chinese herbal medicine, could relieve the clinical symptoms of CRF patients, and was considered to have a certain reversal effect on rapid deterioration of renal function. Objective: To observe the changes of serum interleukin-8 (IL-8) and IL-18 levels in CRF patients with a sharp deterioration and dampness-heat syndrome, and to explore the curative efficacy of Qingshen Granule. Design, setting, participants and interventions: Sixty CRF patients with a sharp deterioration and dampness-heat syndrome from Department of Nephrology, the First Affiliated Hospital of Anhui College of Traditional Chinese Medicine, were randomly divided into treatment group (30 cases) and control group (30 cases), with another 20 healthy individuals as normal control. The patients in the treatment and control groups were all treated with Jiedu Xiezhuo II, a compound traditional Chinese herbal medicine, given as retention enema. Qingshen Granule was additionally administered to the patients in the treatment group with 1 dosage each time and 3 times a day. The treatment course was one month. Main outcome measures: The levels of serum IL-8 and IL-18 in the normal individuals and before and after treatment in the treatment and control groups were detected. Results: The total response rates of treatment group in clinical efficacy assessment and assessment of syndrome of traditional Chinese medicine (86.67% and 86.67%) were higher than those of the control group (56.67% and 60%), and there were significant differences between the two groups (P<0.05). The levels of serum IL-8 and IL-18 in CRF patients before treatment were obviously higher than those in the healthy individuals (P<0.01), and there were no differences in the levels of IL-8 and IL-18 before treatment between the treatment group and control group (P>0.05). After one-month treatment, the levels of serum IL-8 and IL-18 were markedly decreased in the two groups (P<0.01), and the levels of serum IL-8 and IL-18 in the treatment group were markedly lower than those in the control group (P<0.05). There were differences in decreased degrees of IL-8 and IL-18 levels between the two groups (P<0.05). Conclusion: CRF patients with a sharp deterioration and dampness-heat syndrome have high serum IL-8 and IL-18 levels. Qingshen Granule can reduce the levels of serum IL-8 and IL-18, and improve the renal function and ameliorate the clinical symptoms.

Objective To investigate the effect of arterial and venous subarachnoid hemorrhage ( SAH)on voltage-dependent calcium channel( VDCC)currents of cerebral artery smooth muscle cells and the relationship between the concentration of oxyhemoglobin( OxyHb)in arterial and venous blood and cerebral blood flow. Methods Thirty-six clean grade rats were colleted. A rat SAH model was induced by injection of autologous arterial or venous blood in suprasellar cistern using assisted stereotaxic apparatus. The rats were divided into three groups:an arterial SAH( n=14 ),a venous SAH( n=13 ),and a sham operation( n=9 )group. The arterial and venous OxyHb concentrations were measured. Three days after SAH modeling,a patch clamp was used to detect the relative surface area of the cerebral artery smooth muscle cells,resting potential,and VDCC currents in rats. A fluorescent microsphere method was used to quantitatively analyze cerebral blood flow(CBF). Results (1)Arterial SAH OxyHb concentration (127 ± 4 g/L)was significantly higher than venous SAH OxyHb concentration(54 ± 6 g/L),and that of the sham operation group was 50 ± 5 g/L. The differences were statistically significant among the 3 groups( P<0. 01).(2)The maximum current of VDCC of the arterial SAH group(3. 22 ± 0. 31 pA)was significantly higher than that of the venous SAH group(2. 19 ± 0. 27 pA)and the sham operation group(2. 18 ± 0. 29 pA). The differences were statistically significant among the 3 groups( P<0. 01 ). The VDCC currents of the arterial SAH group were consisted of L- and R-currents,while the currents of the venous SAH group were only consisted of L-VDCC.(3)The cerebral blood flow of the arterial SAH group(0. 83 ± 0. 14 mL/[g·min])was significantly higher than that of the venous SAH group(1. 28 ± 0. 28 mL/[g·min])and the sham operation group(1. 35 ± 0. 19 mL/[g·min]). The differences were statistically significant(P<0. 01). Conclusions The changing effect of arterial SAH on the expression and function of the cerebral artery smooth muscle cells are greater than that of the venous SAH. This difference may be associated with the concentration and composition of vasospasm factors of OxyHb in arterial and venous blood.
