Pharmacological activities of the effective constituents: essential oils, flavonoids andalkaloids, in fruit of Citrus aurantium L. were compared. Blood pressure was increased markedly by transfusion of the alkaloids. Contractions of isolated intestines were iuhibited byflavonoids. Essential oils significantly decreased the rate and frequency of writhing syndromeinduced by ip acetie acid and spontaneous locomotor activities in the mice with the exceptionfexciting at first followed by inhibiting the isolated intestines,which displayed analgesia andoceutral inhibition to a certain extent.

OBJECTIVE:To survey and objectively evaluate the present situation and trend of the antihistamine agents used in 18 hospitals of Hangzhou.METHODS:To make a survey of the use of above mentioned drugs in 18 hospitals of Hangzhou during the period 2000～2002 in respect to the sum of money for drugs and manufacturing factories.RESULTS:In comparison with 2001,the sum of money for consumption of antihistamine agents increased 17.89%in 2000,and decreased 4.58%in 2002.Joint venture and imported products accounted for 70%of share of market.Lortadine and Cetirizine were still the first choice in therapy of allergic reactions.CONCLUSION:Consumption of antihistamine agents decreased,but kinds of drugs had no obvious change.

OBJECTIVE　To study the effects of Panax quinquef olium 20S-protopanaxdiol saponins extracted from the leaves of panax qu inque-folium (PQDS) on the hemodynamics and cardial oxygen metabolism in dogs with acute myocardial infarction (AMI).METHODS　The paramete rs of hemodynamics and cardial oxygen metabolism were determined by using the mo del of ligation of LAD in the anaesthetized open-chest dogs.RESULTS 　In dogs treated with PQDS (in a dosage of 10 and 20 mg*kg-1 iv infusion),the myocardial blood flow (MBF) was increased and coronary vascular re sistance (CVR) was decreased significantly.The heart rate (HR) was slowed.The ar terial blood pressure (ABP),left ventricular pressure (LVP),the maximum rise rat e of left ventricular pressure(+dp/dtmax),left ventricular work index (LVW I) and total periphery resistance(TPR) were reduced,whereas the stroke index(SI) and cardiac index (CI) were increased.In addition,the decreasing range of the m aximum decline rate of left ventricular pressure(-dp/dtmax) and the rising range of left ventricular end diastolic pressure (LVEDP) were reduced.Meanwhile the cardiac oxygen consumption,myocardial oxygen utilization rate and cardiac o xygen consumption index were also decreased.CONCLUSION　PQDS had protective effects on acute myocardial ischemia including improving heart fu nction,decreasing cardiac oxygen consumption and increasing myocardial blood flo w,etc.

Objective To observe the protective effects of Diemailing Injection (DMLI) on myocardial ischemia-reperfusion injury in rats. Methods The myocardial ischemia-reperfusion model was induced by 30 min left anterior descending coronary occulusion and 24 h reperfusion in open-chest anesthetized rats. The changes of aspartate aminotransferase (AST), lactate dehydrogenase (LDH), MB isoenzyme of creatine kinase (CK-MB), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities and malondialdehyde (MDA) contents in serum, and prostacycline (PGI2) and thromboxane A2 (TXA2) levels in plasma were determined. Results In rats treated by DMLI (with dose of 2. 5, 5 and 10 mL ? kg-1 i. v. at 30 min after coronary occulusion), the myocardial ischemia size (MIS) was significantly reduced, the AST, LDH and CK-MB activities in serum and the TXA2 level in plasma were declined, while PGI2 level in plasma and PGI2/TXA2 ratio were increased significantly. In addition, the LPO content in serum declined, SOD and GSH-Px activities in serum were increased markedly. Conclusion DMLI has protective effects on myocardial ischemia-reperfusion injury through improving free radicals metabolism, decreasing TXA2 level in plasma, increasing PGI2 level in plasma and PGI2/TXA2 ratio.

OBJECTIVE: To study the therapeutic mechanism of salvianolic acid B (SA-B) in treating hepatic fibrosis. METHODS: Twenty-four Wistar rats were randomly divided into 3 groups: normal control group, untreated group and SA-B-treated group. Rats in the untreated and SA-B-treated groups were injected intraperitoneally with 0.5% dimethylnitrosamine (DMN) for 4 weeks, daily for 3 days each week at a dose of 10 microg/kg, to induce hepatic fibrosis. Then, rats in the SA-B-treated group were given SA-B orally for another 4 weeks. Hydroxyproline (Hyp) contents in liver tissue of the rats in 3 groups were determined with HCl hydrolysis, and collagen type I, transforming growth factor-beta 1 (TGF-beta1), transforming growth factor-beta receptor type I (TbetaRI) and transforming growth factor-beta receptor type II (TbetaRII) were detected by Western blotting. RESULTS: The Hyp content and the expressions of collagen type I, TGF-beta1, TbetaRI and TbetaRII in the liver tissue of rats in the untreated group increased significantly as compared with those in the normal control group, while those in SA-B-treated group decreased significantly as compared with those in the untreated group. CONCLUSION: The therapeutic mechanism of SA-B in treating hepatic fibrosis may be related to inhibiting the expressions of TGF-beta1 and its receptors.

Oral and maxillofacial surgery is one kind of special subjects involving multiple clinical disciplines.The postgraduate training is different from other professional postgraduate training model,which emphasizes the cultivation of students,should be first medical students,then dentist.In new situation,we advance the experiences in exploring how to cultivate high quality postgraduate of oral and maxillofacial surgery.

Objective: To develop a simple LC MS/MS method for the measurement of limonin in fructus evodiae, cortex phellodendri, cortex dictamni and its preparation. Methods: Separation was obtained by using a discovery C 18 column (150mm?2.1 mm), The mobile phase:A:water-0.1%HAc;B:acetonitrile-0.1%HAc;The elution program was gradient and the flow rate was 0.2mL?min -1 . The mass detector was set MS1(IS)=187.0 and MS2(Limonin)=471.0 by multiple reaction monitor(MRM) respectively.The sample was added psoralen(IS), then extracted with methanol chloroform(1∶3).Results: Limonin was linear from 25 to 1000ng?mL -1 ( r = 0.9996), The regression equation was C=3.124 As/Ai 1.935?10 -3 . The average recovery was 100.2%.Conclusion: This method is simple, quick, sensitive and exclusive.

Objective:To explore the effects of clinical nursing path model on depression and anxiety among rectal cancer patients with stoma.Methods:From January 2017 to December 2018, this study selected 100 rectal cancer patients with stoma in the First Affiliated Hospital of Nanjing Medical University. All of patients were randomly divided into control group and intervention group with the method of random number table, 50 cases in each group. Patients of two groups all received routine nursing. On the basis of routine nursing, observation group carried out the intervention based on the clinical nursing path model. Depression and anxiety before and after intervention was assessed with the Patient Health Questionnaire-9 (PHQ-9) and the Generalized Anxiety Disorder-7 (GAD-7) .Results:Before intervention, there was no statistical difference in the scores of PHQ-9 of patients between two groups ( t=0.116, P=0.908) . After intervention, the score of PHQ-9 of intervention group was lower than that of control group with a statistical difference ( t=6.083, P<0.01) , and lower than that before intervention also with a statistical difference ( t=7.676, P<0.01) . Before intervention, there was no statistical difference in the scores of GAD-7 patients between two groups ( t=0.227, P=0.821) . After intervention, the score of GAD-7 of intervention group was lower than that of control group with a statistical difference ( t=9.249, P<0.01) ; scores of GAD-7 of two groups were lower than that before intervention also with statistical differences ( P<0.01) . Conclusions:Application of clinical nursing path model can effectively improve depression and anxiety of rectal cancer patients with stoma.
