Objective:To investigate the clinical efficacy of trimetazidine combined with salvia ligustrazine injections in the treat-ment of unstable angina in coronary heart disease with type 2 diabetes. Methods:Totally 76 patients of unstable angina with type 2 di-abetes were randomly divided into the control group and the observation group with 38 cases in each. The control group received trime-tazidine on the basis of the conventional treatment, 20mg,po,tid, while the patients in the observation group received salvia ligustrazine injections additionally, 10ml, ivd,qd. The treatment course was 2 weeks, and the clinical efficacy, blood fat, blood rheology and the other indices were observed after the treatment. Results:After the treatment, the effective rate of the control group and the observation group was 65. 79% and 86. 84%,respectively with statistically significant difference(P<0. 05), the improvement of blood fat and blood rheology in the observation group was better than that in the control group (P<0. 05), the angina frequency and duration, and nitroglycerin consumption in the observation group was significantly lower than those in the control group(P<0. 05). Conclusion:The combination application containing trimetazidine and salvia ligustrazine shows exact clinical efficacy with promising safety and compli-ance, which is valuable in the clinical application.

Background:In recent years, there has been rapid growth in pharmaceutical spending in China. In addition, the country faces many challenges with regards to the quality, pricing and affordability of drugs. Pricing and reimbursement are important aspects of pharmaceutical policy that must be prioritised in order to address the man-y challenges. Methods:This review draws on multiple sources of information. A review of the academic and grey lit-erature along with official government statistics were combined with informa-tion from seminars held by China's State Council Development Research Center to provide an overview of pharmaceutical pricing and reimbursement in China. Results:Pricing and reimbursement policy were analysed through a framework that incor-porates supply-side policies, proxy-demand policies and demand-side policies. China's current pharmaceutical policies interact in such a way to create dysfunction in the form of high prices, low drug quality, irrational prescribing and problems with access. Fi-nally, the country's fragmented regulatory environment hampers pharmaceutical policy reform. Conclusions:The pri-cing and reimbursement policy landscape can be improved through higher drug quality standards, greater market con-centration, an increase in government subsidies, quality-oriented tendering, wider implementation of the zero mark-up policy, through linking reimbursement with rational prescribing, and the promotion of health technology assess-ment and comparative effectiveness research. Addressing broader issues of regulatory fragmentation, the lack of trans-parency and corruption will help ensure that policies are created in a coherent, evidence-based fashion.

Objective: To establish Candida albicans vaginitis in mice and explore the best modeling conditions to provide an economical and practical animal model of Candida albicans vaginitis.Methods: After given estradiol valerate respectively at low, medium and high dose (0.001 5, 0.015, 0.15 mg/10 g) by gavage for continual 7 days, Kunming female mice were inoculated Candida albicans to establish the vaginitis model.The amount of Candida albicans in vaginal lavage fluid was analyzed and the vaginal pathological changes were observed.Results: The colony count in vaginal lavage with estradiol valerate at low, medium and high dose was 124.67±19.01, 217.67±22.50 and 282.00±27.87, respectively, and compared with that in the high dose group, there were significant differences in the medium dose group and low dose group (P＜0.05 or P＜0.01).HE staining and PAS staining showed that the high dose group had more polymorphonuclear neutrophils (PMNs) infiltration and purple red line hypha.Conclusion: Estradiol valerate at high dose is the best modeling condition for Candida albicans vaginitis in mice.

Objective To investigate the expression and clinical significance of soluble E-cadherin (sE-cad) and E-cadherin (E-cad) in acute leukemia (AL), and to explore their relationship with the pathogenesis,development and diagnosis of extra-myeloid leukemia. Methods 87 newly diagnosed or relapsed AL patients (19 cases of L1, 29 L2, 14 M2, 20 M3, 4 M4, 1 M5) were collected from hospitalized patients in hematology department of Harbin Medical University Cancer Hospital. The plasma from 20 healthy volunteers was used as control group. The bone marrow was from 15 non-AL patients hospitalized in hematology department (7 cases of thrombocytopenic purpura, 4 iron deficiency anemia, and 4 fever). The expression of sE-cad in the plasma of 47 patients and 20 healthy volunteers was detected by ELISA; the expression of E-cad on the membrane surface of bone marrow MNC in 40 patients and 15 controls was determined by flow cytometry. Results The plasma level of sE-cad in AL group was significantly higher than that in healthy control group [(66.812±52.712) ng/ml vs. (17.976±14.206) ng/ml, P<0.01]. The plasma level of sE-cad in extra-myeloid infiltration AL group was significantly higher than that in no-extra-myeloid infiltration AL group [(83.545±60.759) ng/ml vs. (42.152±22.043) ng/ml, P<0.01]. The plasma level of sE-cad in high leukocytes AL group was higher than that in no-high leukocytes AL group [(85.166±57.828) ng/ml vs. (41.933±32.064) ng/ml, P<0.05]. The percentage of E-cad expression in AL group was significantly lower than that in control group [(13.615±14.038) % vs. (31.700±16.213) %, P<0.01]. The percentage of E-cad expression in no-extra-myeloid infiltration AL group was significantly higher than that in extra-myeloid leukemia infiltration AL group[(18.691±14.917) % vs. (6.589±8.959) %,P<0.01]. The percentage of E-cad in no-high-leukocytes AL group was significantly higher in high leukocytes AL group [(20.925±12.081) % vs. (7.446±11.118) %, P<0.01]. Conclusions The expression of E-cad on the membrane surface of bone marrow MNC and the expression of sE-cad in plasma may be closely associated with the occurrence of extra-myeloid leukemia and leukocytosis, which may be one of the important molecular mechanisms of leukemic cell infiltration and leukocytosis. High expression of sE-cad in plasma can be treated as one of index to diagnose extra-myeloid leukemia.
