Objective To confirm the effect of lymphangiogenesis in immunological reaction on pterygium formation and development.Methods The clinical removal of pterygium material in quiescent phase,advanced phase and recurrent phase was selected.each phase with 12 cases,while 10 cases of normal bulbar conjunctiva were taken as control.5'-nueleotide enzyme-alkallne phosphat&se-double enzyme histochemistry was performed to compare the number of lymphangiogenesis in different tissues.Results Lymphangiogenesis in normal bulbar conjunctiva and quiescent phase pterygium tissues expressed little,but gray-stained lymphangiogenesis widely distributed in pterygium tissue of advanced phase and recurrent phase,and there were statistically significant differences compare those with the normal bulbar conjunctiva and quiescent phase pterygium(P=0.03 and 0.01).Conclusion Lymphangiogenesis may be involved in immunity process of pterygium pathogenesis.

Objective To investigate and analyze the influence of whole blood specimens storage time in blood routine examination parameters. Methods All 40 healthy cases were randomly selected, and all the whole blood specimens were stored at 4℃. 1,2,3,5 and 7 days after the blood sampling,the specimens were tested by Sysmex-XS1000 au-tomated hematology analyzer, and statistical analysis was conducted. Results The specimens were kept in refrigerator at 4℃,for 7 days, WBC, RBC, Hb, MCH, PLT, RDW-CV, N, L, M and E could still maintain stable. There was no significant difference(P>0.05)in comparing all the measurement data and the fresh sample measurement data. HCT,MCV,RDW-SD and B% gradually increased after 3 days, and MCHC gradually decreased. The difference was statis-tically significant (P<0.05). Conclusion Complete blood count specimens can store at 4℃ for 3 days. The results are relatively stable,and parts of main analysis indicators results can still remain stable for a week.

Objective To study the pathological changes of the sudden death cases due to the dysplasia of the cardiac conduction system. Methods Using the newly established pathological sampling method by our research team, 26 hearts of unidentified sudden deaths excluding trauma, poisoning and diseases were collected and observed optically with H&E staining, Masson staining and immunohistochemical staining. Results Among the 26 cases, there were dysplasia in the cardiac conduction system,structural abnormalities, tissue or structure shift, fibrous cushion in the sinoatrial node and 9 cases have 2~3 abnormalities at the same time. Among the age groups from 16 to 30, 21 cases (80.8%) showed dysplasia of the cardiac conduction system. Conclusion The dysplasia of the cardiac conduction system may be one of the predominant reasons for the sudden death in young adults.

OBJECTIVE： To descriptively analyze the status quo of medication therapy management （MTM） at home and abroad， and to provide reference for the development of MTM in China. METHODS：Retrieved from PubMed， Embase， Cochrane Library， CNKI， VIP， Wanfang database， CBM，and simultaneously searched Google and Baidu， retrieve time from the database establishment to March 2019， Chinese retrieval words： “medication therapy management”， English retrieval words： “Medication therapy management” “Management”“Medication therapy”“Therapy management”“Medication”“Drug therapy management”， etc. Domestic and foreign MTM literatures were included. Descriptive analysis was conducted in terms of literature publication， research type distribution， disease distribution and the status quo of MTM literatures in women and children. The necessity and feasibility of MTM in the field of women and children were analyzed. RESULTS & CONCLUSIONS： A total of 403 MTM related literatures （344 foreign， 59 domestic） were included. Among them， the foreign MTM literatures had 154 secondary researches and 190 original studies， clinical value， economic value and humanistic value of MTM were studied in repsects of service providers， service objects， service processes， service effects and other parties. Domestic MTM literatures had 37 secondary researches and 22 original researches， which mainly introduced the US MTM， including implementation background， concept， elements， application status， etc.； the significance and prospects of MTM in China were analyzed. Domestic and foreign MTM literatures mostly focused on chronic diseases in the elderly， mainly endocrine and cardiovascular diseases， such as hypertension， diabetes， and kidney disease. 11 studies about women and children MTM were included （women 5 studies and children 6 studies）； 4 of them were review， 5 were cross-sectional studies， and 2 were case reports. The effects of women and children MTM were introduced in the included literatures from the times of interventions， the number of drug-related problems prevention or improvement， the patient’s clinical outcomes， etc. MTM studies have great differences between at home and aboard in terms of the number of literatures， research types and contents. The researches focus on the field of chronic diseases in the elderly， and there is little literature on MTM in the field of women and children. It is necessary to provide MTM services for women and children in the light of the Millennium Development Goals proposed by the United Nations and the increasing problem of women and children medication. It is suggested to use the MTM model to develop women and children chronic disease pharmaceutical service so as to promote the transformation of pharmacists and improve the quality of pharmaceutical care.
