During the last fifty-year medical treatments have made great advances in the treatment of heart failure(HF).The current applicatin of treatment improves the life quality of patients with HF,and reduces their clinical envents and mortality.But the patients with refractory heart failure(RHF) have poor prognosis.This article reviews and analyzes the advances in the therapies for patients with RHF.

Objective To inustigate oceular blood flow velocity in the eyes of paicients with diabetic retino pathy.Methods Hemodynamic parameters in the ophthalmic arteny(OA),central retinal artery(CRA) were determined with color Doppler sonography(CDS) in 70 eyes of 35 patients with diabetic retinopathy and 80 eyes of 40 patients of mormal controlts.Results Compared with normal subjects,the patients with diabetic retinopathy showed significant slower hemodynamic pararneters with OA.CRA and higher with resistive index(P

[Objective] To investigate the clinical efficacy of tacalcitol combined Halometasone sequential therapy in the patients of plaque psoriasis. [Methods] 117 cases of plaque psoriasis col ected between 2011.01 and 2013.02 were randomly divided into treatment group and control group. The treatment group were treated with tacalcitol and Halometasone therapy, and required topical use Halometasone(1 time/day) in the morning ,tacalcitol use in the evening(1 time/day) before the first 2 weeks. Continuous two weeks treatment from Monday to Friday with tacalcitol(2 times/day), Saturday and Sunday with Halometasone(2 times/day), final y the transition to be used alone tacalcitol(2 times/day) in the next two weeks of continuous treatment. Control group of pa-tients given alone Halometasone(2 times/day) for 6 consecutive weeks. Observe the adverse reactions PASI scores during and after completion of treatment within the two groups. Al patients were fol owed for three months, observed recurrence. [Results] The PASI score between two groups of patients declined during treatment, especial y at the 4th and 6th week within the treatment group. Both groups had no serious adverse reactions. In treatment group, 54 patients had effective responses, the total effective rate was 90%, significantly better than the control group(41 cases,71.9%). In the fol ow-up of 3 months, the recur-rence rate was 11.1%in the treatment group, significantly lower than the control group(31.6%). The difference of total efficiency and the recurrence rate with-in the two groups was statistical y significant. [Conclusion] Tacalcitol combined Halometasone sequential therapy of plaque psoriasis has significant clinical effi-cacy and low recurrence rate.

Food allergy is a common allergic disease.The severity and incidence of food allergy reaction which increases gradually in recent years has seriously affected the healthy growth of infants and toddlers.Although the use of animal models to study the pathogenesis and prevention of food allergy has become the most important and common method because of the restrictions of clinical research,the international standard of food allergy model has not been established yet.Researchers often use milk,egg and peanuts which are very important food sources of infants and toddlers as allergens in animal models on the pathogenesis and control strategies.This article summarizes the research progress of animal models of milk,egg and peanuts,which will be helpful for researchers to choose animal model due to different purpose.

Objective In order to optimize patient's medical treatment processes, and to improve the working efficiency of health care professionals and the quality of medical services. Methods The design and application of the electronic prescription module were introduced, and its advantages and existing problems were discussed. Results The electronic prescription module were applied generally. Orthodox patient's medical treatment processes were changed and the prescription management was normalized. Conclusion The electronic prescription module is one of the core components of the workstation system for the out-patient physicians. It optimizes the patient's medical treatment processes and improves the efficiency and the quality of medical services.

Objective To investigate the effects of titanium nitride(TiN) coating on corrosion resistance of dental Co-Cr alloy in the simulated oral environment. Methods The Co-Cr alloy commonly used was casted with specimen sized of 10 mm× 10 mm×3 mm. Then the specimen was coated with a thickness of 2.5 μm TiN coating on the surface by multi-arc physical vapor deposition. The Tafel polarization curves of the specimen before and after coating titanium nitride in artificial saliva were measured by electrochemical station. Results From the Tafel polarization curves, the specimen after coating TiN showed that both anodic polarization curve and cathodal polarization curve were fiat, natural corrosion potential moved to the positive way, and passivation interval got longer. From the annular anodic polarization curves, the specimen after coating TiN had almost no "delay area". Conclusion TiN coating can improve corrosion resistance of Co-Cr alloy.

With the illustration of the L-Arg-NO-cGMP pathway in penile erection,the researches on nitric oxide synthases(NOSs),which produce nitric oxide(NO)as the main messenger to control the process,has stayed in the spotlight.nNOS locates in neuroal tissues and eNOS is binding on the membrane of cavernous sinus endothelium with caveolin.The nNOS & eNOS are expressed constitutively.The activation of nNOS & eNOS is more dependent on Ca2+ concentration than iNOS,which is seldom expressed except in aged or pathological conditions.It is now clear that nNOS may initiate cavernosal tissue relaxation under the regulation of PDZ zone when transcripted,while phosphorylated eNOS may facilitate attainment and maintenance of full erection.iNOS expression stimulated by the cytokines may be beneficial(cytoprotective or anti-fibrotic)or deleterious(cytotoxic)according to the tissue environment.Gene therapies based on NOSs have attained a great deal of achievements in animal experiments and will promise a wonderful future.

OBJECTIVE:To provide reference for the quality management of hospital preparation in medical institution.METHODS:The relationship between the cause for some typical ADR events such as "Armillarisin A Injury","Xinfu Injury","Methotrexate Injury","Aesculus Wilsonii Rehd Injury" and drug production were discussed and analyzed by combining with status quo of preparation management in hospital.RESULTS & CONCLUSIONS:Above ADR events were connected with quality management in drug production closely.The quality management system of hospital preparation should be established to strengthen management of whole preparation process and guarantee the safety of hospital preparation.

Objective:To analyze the pharmaceutical care performed by clinical pharmacist for one patient with biliary tract infec -tion to investigate the role of clinical pharmacists in clinical treatment .Methods:The clinical pharmacist supervised the whole process of treatment for the patient and optimized the treatment regimen together with the clinical doctors to achieve good efficacy .Results:With the cooperation of clinical pharmacist , the clinical doctors changed the treatment drugs to avoid the potential adverse drug reac -tions until the patient was cured .Conclusion:The participation of clinical pharmacist in the pharmaceutical care for the patients with biliary tract infection can provide a new thought of working mode .

Congenital heart disease often lost the opportunity of radical sureryfor secondary pulmonary hypertension.pulmonary hypertension is pathologicallycharacterizzed by pulmonary vascular remodeling,including the vascular smooth musclecell' s proliferation,migration and extracelluar matrix deposition,Recently,someresearchers have found that connective tissue growth factor can bind with somesurface receptors of vascular smooth muscle cells,causing some biological behaviorchanges such as proliferation,migration and extracellular matrix abnormaldeposition,and activating crresponding gene expression through this signaltransduction pathway.Pulmonary vascular remodeling may be one of the molecularpathogenesis in pulmonary hypertension.
