OBJECTIVE: To understand the prevalence of chronic diseases and the demands of pharmaceutical care in the ederly, and to explore the content and mode of pharmaceutical care for elderly people. METHODS: A questionnaire survey was conducted in 1262 people over 60 years old, and the data were processed by SPSS. RESULTS: Respondents' prevalence rate of chronic diseases was as high as 95.2%, the top three chronic diseases was hypertension, bone hyperplasia/osteoporosis and coronary heart disease. The respondents' cognition and evaluation of pharmacists and pharmaceutical care needed to be improved, their pharmaceutical care needs mainly concentrated in the popularization education of medication particularity, the detailed explanation of drug instructions and the coping measures to common adverse drug reactions; lectures, face-to-face communication, pamphlets were more acceptable for the elderly to carry out pharmaceutical care. CONCLUSION: The health status of the elderly is not optimistic, and they generally have an urgent need for pharmaceutical care. Pharmacists should improve their ability, to carry out various pharmaceutical care to meet the needs of the elderly.

Objective To provide references for rational clinical usage and purchase of TCM decoction pieces for blood-activating and stasis-removing. Methods Excel 2013 software was used to conduct statistical analysis on categories, consumption quantity, consumption sum and annual average growth rate of TCM decoction pieces for blood-activating and stasis-removing during 2011-2015 in TCM Hospital of Jiangsu Province (hereinafter refered to as our hospital). Results The consumption quantity and consumption sum of TCM decoction pieces for blood-activating and stasis-removing in our hospital increased year by year. Among all types of TCM decoction pieces for blood-activating and stasis-removing, TCM decoction pieces for activating blood and adjusting maridians occupied the largest amount, followed by TCM decoction pieces for activating blood and relieving pains, breaking up the static blood and eliminating masses, and blood-activating and wound - curing. The TCM decoction pieces with the biggest annual consumption quantity were Salviae Miltiorrhizae Radix et Rhizoma, Chuanxiong Rhizoma, and Curcumae Radix, and the TCM decoction pieces with the biggest annual consumption sum were Notoginseng Radix et Rhizoma, Salviae Miltiorrhizae Radix et Rhizoma, and Carthami Flos. Conclusion Both the consumption quantity and the consumption sum of the TCM decoction pieces for blood-activating and stasis-removing in our hospital have been increasing year by year. However, the proportion consumption quantity and the consumption sum of TCM decoction pieces and medicine utilization structure have kept stable, and in basically rational use.

Objective To research the curative effect of the chronic refractory skin ulcer,which belong to yang deficiency of both spleen and kidney type with the treatment of Huiyang Shengji ointment,and discuss the mechanism at cell and molecular level.Methods According to the diagnostic criteria,102 patients were divided into the treatment group(treated with topical Huiyang Shengji ointment) and the control group(treated with topical chlorhexidine).The effects were summarized six weeks later.The marginal tissue of the patients with the chronic skin ulcer was taken to analyze collagen Ⅰ/Ⅲ with the software and the expression of cytokine FGF-2,VEGF,Fn were observed during the wound heal.Results The effective rate was 50% in the treatment group,the control group was 33.33%,with statistical differences.Huiyang Shengji ointment can change the status of the chronic wound,promote growth of new blood vessels and improve the collagen synthesis,especially collagenⅠ.The expression of the FGF-2 and VEGF in the marginal tissue of the chronic skin ulcer showed a rising trend.Conclusions Huiyang Shengji ointment can accelerate the wound heal of chronic refractory skin ulcer.One of the mechanisms is related to promoting growth of new blood vessels and improving the collagen synthesis.

Objective To investigate the interference effect of nerve growth factor (NGF) on apoptosis of retinal cells in experimental retinal detachment (RD). Methods Twenty seven Sprague-Dawely rats were selected, and the left and right eyes were in the experimental control group and NGF group, respectively. After the RD model was set up by subretinal injection with sodium hyaluronate, 5 ?l NGF (1 ?g?l) was injected into the vitreous body of the right eyes which were in the NGF group; 5 ?l PBS was injected into vitreous body of left eyes which were in the experimental control group. The injection was performed once every 4 days till the end of the observation period. The eye balls of the 27 rats were extrafted 1.5, 3, 6, 12 hours, 1 day, 2, 4, 8, 16, and 32 days after the RD model was established. Another 2 rats were selected as the normal control, which underwent none of the injections but eyeball extraction at the end of the observation period. TUNEL and transmission electron microscopy were used to detect the apoptosis of the retinal cells. Cell counts and statistical analysis were used to assess results. Results Typical apoptosis cells were observed in the early time of RD. Apoptosis was found in each retinal layers, especially in inner and outer nuclear layers. The number of apoptosis cells increased as the time of RD was prolonged(P
