篈 new diterpene,rabdonervosin A(I ) was isolated from an ethanolic extract of the leaves and stems ofRabdosia nervosa co1lected in Jiangxi,China. Its structure was established as 1Q, 69, 15Attihydroxy-6, 7-B-sec-oent-kaur-16-en-6, 20-epoxy-7, 20-8-olide on basis of spectroscopic data.

Objective To investigate the effects of established swine acute myocardial infarction and following ventricular remodeling model by occluding Coronary with balloon. Methods Ten healthy Domestic swine are enrolled. Each swine's left anterior descending coronary artery was occluded for three hours by dilated balloon, and then reperfusion was performed. During the whole course of operation, the electro-cardiogram was monitored. B-ultrasound and single -photon emission computed tomography examination (SPECT) were performed to detect left ventricular end diastolic dimension, left ventricular tip wall thickness, left ventricular end diastolic volume and left ventricula ejection fraction before operation and one week, three month, six month after acute myocardial infarction. Results Five swine died during the period of opera-tion for lack of experience, the remains survived. Electrocardiogram revealed significant ST-elevation and Q-wave formation. B-untrasound and SPECT witnessed deteriorating left ventricular end diastolic dimension expansion, left ventricular tip wall thickness thinning, left ventricular end diastolic volume expansion and left ventricular ejection fraction depression. Conclusions Coronary artery occlusion by balloon can successfully establish acute myocardial infarction and following left ventricular remodeling models.

AIM:To evaluate the relationship between RUNX3,cyclin E,P21,biological features and survival in gastric cancer patients.METHODS:RUNX3 was examined using immunohistochemical staining.Cyclin E and P21 were analyzed by flow cytometry.Survival was evaluated by Kaplan-Meier survival curves.RESULTS:The positive-expression rate of RUNX3,cyclin E and P21 in tumor tissue from 56 patients with gastric cancer were 44.6%,64.3% and 32.1%,respectively.RUNX3 expression was correlated with lymph node metastasis and distant metastasis(P0.05).Using Kaplan-Meier survival curves and the Log-rank test,there was correlation between RUNX3,cyclin E and survival(P0.05).CONCLUSION:RUNX3 may be related with tumorigenesis and tumor progression by affecting P21 expression.The detection of RUNX3 and cyclin E may be helpful in evaluating the clinicopathological parameters and prognosis in gastric carcinoma patients.

Objective To investigate the relationship of the cytogenetic abnormalities detected by FISH in patients with MM and their clinical features. Methods FISH on bone marrow (BM) cells was performed in 57 enrolled MM patients. Relationships between cytogenetic abnormalities and clinical features were analyzed. Results By statistical analysis , both D13S319 deletion and RB1 deletion were associated with high level of serum LDH (P = 0.024; P = 0.018) and BM plasma cells index (P = 0.027; P = 0.013). 1q21 amplification was significantly associated with high level of LDH (P = 0.030 ) and the occurence of light chain type myeloma (P = 0.023). IgH rearrangement was associated with renal function damage (P = 0.009). There were correlations among D13S319 deletion, RB1 deletion, 1q21 amplification and IgH rearrangement (P<0.01). Conclusion The genetic abnormalities detected by FISH in patients with MM were correlated with various clinical poor prognostic indicators, which can evaluate the condition and prognosis of patients more efficiently.

Objective To investigate the effects of bone marrow stem cells autologous transplantation on left ventricular remodeling after acute myocardial infarction. Methods Acute myocardial infarction models were successfully established in 10 swines, which were ran-dom divided into two groups, placebo group and trasplantation group. One week after operation, bone marrow stem cells autologous transplan-tation was performed, and control group was administrated with placebo. B-ultrasound and emission computed tomography aexaminations were performed to assess the left ventrieular end diastolic dimension, left ventricular tip wall thickness, left ventricular end diastolic volume and left ventricula ejection fraction before operation, one week, three months after acute myocardial infarction. Results Compared with that of control group, three months after acute myocardial infarction, transplantation group witnessed smaller left ventricular end diastolic dimension, thicker left ventricular tip wall, smaller left ventricular end diastolic volume and higher left ventricular ejection fraction. Conclusions Bone marrow autologous transplantation after acute myocardial infarction can alleviate left ventricular remodeling.

A 69-year old female patient was admitted because of 3 days of worsened chest pain.Coronary angiography showed60% stenosis of distal left main stem,chronic total occlusion of left anterior descending (LAD),70% stenosis at the ostium of a smallleft circumflex,70-90%stenosis at the paroxysmal and middle part of a dominant fight coronary artery (RCA),and a normal left internalmammary artery (LIMA) with normal origination and orientation.Percutaneous intervention was attempted but failed on the occludedlesion of LAD.The patient received minimally invasive direct coronary artery bypass (MIDCAB) with left LIMA isolation by Davincirobot.Eleven days later,the RCA lesion was treated by Sirolimus Rapamicin eluting stents implantation percutaneously.Then thepatient was discharged uneventfully after 3 days hospitalization.Our experience suggests that two stop shops of hybrid technique befeasible and safe in the treatment of elderly patient with multiple coronary diseases.

Objective To explore the application of Plan-Do-Check-Act(PDCA)cycle management to continuously im-prove the service quality of outpatient pharmacy and enhance patient satisfaction.Methods To address the problem of long wait-ing time for patients in outpatient pharmacy,we applied PDCA cycle to investigate the factors affecting patients'waiting time in the process of medicine collection,analyze the current situation,determine the expected goals,formulate the service quality im-provement plan of outpatient pharmacy,implement the improvement plan,follow up and supervise,and summarize and analyse the problems regularly until it was solved.Results After implementing the PDCA cycle in the management,the service quality of outpatient pharmacy was improved,the waiting time was significantly shortened and the satisfaction of medical treatment was in-creased.Conclusion The application of PDCA cycle method is effective in improving the service quality of outpatient pharmacy.Therefore,it is recommended for broader implementation.
