Converting two poorly water-soluble crystalline drugs to co-amorphous drug systems by ball milling, quench-cooling, or cryo-milling method can improve stability of the drug, enhance dissolution rates, and reduce adverse reactions of the single drug. Co-amorphous system has been used to solve problems of co-administration of medicines. Formation and intermolecular interactions of co-amorphous drug systems may be verified by differential scanning calorimetry (DSC), X-ray powder diffraction (XRPD), Raman spectroscopy (RS) and Fourier transform infrared spectroscopy (FT-IR). Stability of co-amorphous drug systems is influenced by their glass transition temperature (Tg) and intermolecular interactions. The theoretical Tg values and the interaction parameter x are calculated by Gordon-Taylor equation and the Flory-Huggins equation, respectively. Thus, co-amorphous drug systems are analyzed theoretically at molecular level. Co-amorphous drug systems provide a new sight for the co-administration of medicines.

Objective To explore the effects of flunarizine hydrochloride on plasma calcitonin gene-related pep-tide and substance P levels after CSD in a rat migraine model of cortical spreading depression (CSD). Methods Thirty adult rats were randomly and evenly divided into three groups:control Group, CSD group and flunarizine group. The CSD waves were evoked by application of potassium chloride on brain surface with filter paper. Funarizine hydrochloride was intravenously administered to rats five minutes prior to application of potassium chloride. The plasma levels of CGRP and SP were measured by using radioimmunity assay. Statistical analyses were performed using two-sample t test and analy-sis of variance. Results CSD waves were absent in control group whereas CSD waves were induced in CSD and flunari-zine groups. The latency of the first CSD wave was longer in flunarizine group (167.90 ± 25.18 s) than in CSD group (130.90 ± 13.30 s) (P<0.01). The number of CSD waves was smaller in flunarizine group (4.50 ± 1.84) than in CSD group (8.50 ± 2.07) (P<0.01). The amplitude of CSD waves was lower in flunarizine group (11.40 ± 4.12 mv) than in CSD group (24.40±3.57 mv) (P<0.01). The levels of CGRP and SP in both CSD group (CGRP, 32.95±11.61 pg/mL;SP, 27.80±7.51 pg/mL) and flunarizine group (CGRP, 25.13 ± 5.67 pg/mL; SP, 19.45 ± 6.10 pg/mL) were higher than in control group (CGRP, 14.44 ± 6.39 pg/mL; SP, 12.36 ± 4.22 pg/mL) (P<0.01). The levels of CGRP and SP in flunarizine group (CGRP, 25.13±5.67 pg/mL;SP, 19.45±6.10 pg/mL) were lower than those in CSD group (CGRP, 32.95±11.61 pg/mL;SP, 27.80± 7.51 pg/mL) (P<0.05). Conclusions Flunarizine hydrochloride can inhibit CSD and reduce the plama levels of CGRP and SP in the rat model of CSD.

OBJECTIVETo observe the effect of Yiqi Huoxue Qingre Huashi Recipe (YHQHR, a recipe capable of supplementing qi, activating blood, clearing heat, and dissipating dampness) on ulcer healing and Helicobacter pylori (Hp) eradication rate in Hp positive peptic ulcer patients, and to explore coccoid Hp occurrence in the eradication.

METHODSTotally 80 Hp positive peptic ulcer patients were assigned to the treatment group and the control groups by random digit table, 40 in each group. All patients received standard triple therapy of Western medicine for 2 successive weeks. Those in the control group additionally took omeprazole enteric coated tablet, 20 mg each time, once per day for 4 successive weeks. Those in the treatment group additionally took YHQHR, twice per day for 6 successive weeks. The ulcer healing was observed and recorded by gastroscope after discontinued medication of 14 days. The effective rate of ulcer healing under endoscope was statistically calculated. Rapid urease test (RUT) was performed in one small piece of tissue from corpora ventriculi and sinuses ventriculi using 14C breathe test (UBT). Gastric juice was collected from the stomach. Hp urease gene amplification test (urea A-PCR) was performed in living tissue from gastric antrum. Results obtained from the above three test methods were recorded and assessed to decide the final eradiation rate. Gastric mucosa tissue was observed under electron microscope,attempting to find non-eradicated Hp, which was further observed.

RESULTSThe total curative effect under gastroscope was 97.5% (39/40 cases) in the treatment group, obviously higher than that in the control group (80.0%, 32/40 cases) (P < 0.05). The eradication rate of Hp was 75.0% (30/40 cases), obviously better than that of the control group (52.5%, 21/40 cases) (P < 0.05). The total positive Hp numbers after treatment was 14C UBT (12), RUT (8), and urea A-PCR (27), respectively. The Hp positive rate detected by 14C UBT and RUT was lower than the Hp positive rate detected by urea A-PCR (P < 0.05). Rod-like and coccoid Hp bacteria could be observed under electron microscope.

CONCLUSIONYHQHR combined standard triple therapy was more effective than standard triple therapy alone in promoting ulcer healing and elevating the eradication rate of Hp.

Objective: To analyze the relationship between thrombin activatable fibrinolysis inhibitor ( TAFI ) and coronary heart disease ( CHD ), and to provide evidence for the prevention of CHD. Methods: The patients with CHD in Fushun Central Hospital in Liaoning Province were selected as the case group, the patients without CHD in the same hospital and period were selected as the control group. The demographic information and clinical examination results ( serum TAFI, lipid, glucose, etc. ) were collected to analyze the association between TAFI and CHD by logistic regression models.The multivariate logistic regression analysis was used to explore the relationship between TAFI and CHD. Results: There were 222 cases, including 100 cases of stable angina, 44 cases of unstable angina and 78 cases of acute myocardial infarction, and 222 controls. The median ages of cases and controls were 62 and 57 years old. The results of multivariate logistic regression analysis showed that serum TAFI>22.88 μg/mL ( P75 of controls ) was associated with the risk of CHD ( OR=1.619, 95%CI: 1.011-2.593 ), unstable angina ( OR=2.917, 95%CI: 1.433-5.939 ) and acute myocardial infarction ( OR=2.626, 95%CI: 1.007-6.847 ). Conclusion The high level of TAFI is related to CHD, unstable angina and acute myocardial infarction.

OBJECTIVETo investigate the relationship between the biological features and the treatment efficacy and prognosis in acute myeloid leukemia subtype M2 (AML-M2) patients with chromosome 8 and 21 translocation.

METHODSBy using Cox regression model and Kaplan-Meier analyses, prognostic factors in 54 cases of de novo adult AML with t(8;21) in our institute from 1990 to 2003 were retrospectively analyzed.

RESULTThe complete remission (CR) rates were 81.9% for all M2 patients, 82.4% for patients with normal karyotype, 88.5% for patients with t(8;21) [P > 0.05 for normal karyotype vs t(8;21)], 100.0% for 28 patients with t(8;21) alone and 75.0% for 24 patients with additional chromosome abnormalities (P < 0.01). The actuarial 3 year overall survival(OS) was 26% for M2 patients with normal karyotype, 25% for patients with t(8;21) [P > 0.05 for normal karyotype vs t(8;21)], in whole t(8;21) group, 46.4% for patients with t(8;21) alone and 0% for patients with additional chromosome abnormalities (P < 0.01). Multivariate analysis of prognostic factors showed that chromosome abnormalities besides t(8;21) was the only factor affecting CR, disease-free survival (DFS) and OS. DFS of allogeneic hematopoietic stem cell transplantation (HSCT) and intermediate-dose cytarabine/high dose cytarabine (IDAC) groups were better than the group received routine dose cytarabine as postremission therapy (P < 0.01).

CONCLUSIONAML with t(8;21) is not a single defined AML subset, and patients with additional chromosome abnormalities have a worse prognosis. HSCT and IDAC could improve the outcome. HSCT is the best choice for patients with high risks, especially with additional chromosome abnormalities.
