ABSTRACT
Objective:To observe the efficacy of addition and subtraction therapy of Danshenyin combined with Wendantang in the treatment to stable angina pectoris （SAP） with stagnation of phlegm and blood stasis， and to explore its protection mechanism for myocardial ischemia. Method:One hundred and thirty-two patients were randomly divided into control group and observation group equally. Finished the 63 cases study both in control group and observation group after dropout， loss of follow-up and withdrawal. Patients in control group and observation group got antianginal drugs and the treatment of drug therapy to control the risk factors. All patients were treated with anti-angina drugs and risk factors control drugs. Patients in control group got Danlou Tablets by oral administration， 5 tablets/time， 3 times/day. Patients in observation group got dispensing decoction pieces of Danshenyin and Wendantang 1 dose/day. The treatment continued for 3 months in both groups. Scores of angina attack were graded every week. Before and after treatment， electrocardiogram treadmill exercise test was made to evaluate myocardial ischemia of coronary heart disease， and scores of phlegm stasis block syndrome and Seattle Angina questionnaire （SAQ） were graded for TCM symptoms and quality of life. Levels of hemorheology index， interleukin-6 （IL-6）， tumor necrosis factor-<italic>α</italic> （TNF-<italic>α</italic>）， intercellular adhesion molecule-1 （ICAM-1）， Cystatin C （CysC）， homocysteine （Hcy）， ischemic modified albumin （IMA） and macrophage migration inhibitory factor were detected. In addition， safety was evaluated. Result:After treatment， scores of times， duration， degree of angina pectoris， nitroglycerin dosage of angina pectoris and nitroglycerin dosage in the observation group were lower than those in the control group （<italic>P</italic><0.01）. Total exercise time， duration of ST depression for 1.0 mm， occurrence time of stable angina pectoris， metabolic equivalent and scores of Duke in the observation group were more than those in the control group （<italic>P</italic><0.01）. Score of stagnation of phlegm and blood stasis in the observation group was lower than that in the control group （<italic>P</italic><0.01）， while score of SAQ was higher than that in the control group （<italic>P</italic><0.01）. Levels of IL-6， TNF-<italic>α</italic>， ICAM-1， CysC， IMA， Hcy， MIF， whole blood viscosity （low cut， high cut）， whole blood reducing viscosity， plasma viscosity， platelet aggregation rate and fibrinogen （FIB） in the observation group were lower than those in the control group （<italic>P</italic><0.01）. Effect of angina pectoris in observation group was superior to that in control group （<italic>Z</italic>=2.091， <italic>P</italic><0.01）. No adverse reactions related to Danshenyin combined with Wendantang were found. Conclusion:Addition and subtraction therapy of Danshenyin combined with Wendantang based on the routine western medicine treatment can control the attack of angina pectoris， relieve the symptoms of phlegm and stasis block syndrome， and improve the quality of life for patients with SAP， showing superior clinical efficacy and safety. In addition， it can improve the hemorheology of patients， inhibit the inflammatory reaction， reduce the stenosis or obstruction of lumen in order to improve the degree of myocardial ischemia.
ABSTRACT
<p><b>OBJECTIVE</b>To establish a simple but effective method of laser scanning confocal microscopic imaging for Ca2+ oscillations of pancreatic acinar cells in adult mice.</p><p><b>METHODS</b>Pancreatic acinar cells from adult Kunming mice were isolated acutely with collagenase, and then loaded with fluo-4-AM, a Ca2+ indicator. A laser scanning confocal microscope armed with 488 nm laser was employed to record the dynamic fluorescent signals in-time and synchronously while acetylcholine (ACh) was added in the pancreatic acinar cells.</p><p><b>RESULTS</b>(1) The classic pancreatic acinar cell Ca2+ oscillations were induced by a certain concentration of ACh (100 nmol/L) successfully and steadily, which could be blocked by atropine completely. (2) Plasmic Ca2+ oscillations from different parts of one acinar cell were usually with different amplitudes and almost the same frequencies. But both of amplitudes and frequencies were different among different cells. (3) The acinar cell Ca2+ oscillations were induced by ACh in a concentration-dependent manner.</p><p><b>CONCLUSION</b>The laser scanning confocal microscopic imaging for adult mouse pancreatic acinar cell Ca2+ oscillations was established successfully. The features of being easy to use, direct to see lively, high efficiency and good flexibility make it a popular tool for researchers to choose.</p>
