ABSTRACT
Objective To understand oral health of the elderly in nursing home in Songjiang District, Shanghai, and to provide references for improving their oral health. Methods A total of 375 elderly people in 15 nursing homes in Songjiang District were investigated by questionnaires and oral examination.Tooth loss, denture repair, periodontal condition and oral hygiene habit were analyzed. Results The rate of the tooth loss reached 94.13%.The tooth loss rate in females (96.09%) was significantly higher than that in males (91.03%) (P < 0.01).The rate of complete edentulous jaws was 28.27%.There was a significant difference between the rate of complete edentulous jaws in females (34.35%) and in males (18.62%)(P < 0.05).The rate of denture restoration was 91.51% (97/106).The number of existing teeth per capita was 11.54, and the number of teeth per capita in males (14.48 per person) was significantly higher than that in females (9.70 per person) (P < 0.05).Both the rate of the tooth loss of upper and lower posterior teeth were significantly higher than that of upper and lower anterior teeth (P < 0.01).Thirty-three percent (33.33%) of the elderly brushed their teeth more than twice a day, and almost 20.53% of them didn′t brush their teeth. Conclusion The oral health of the elderly in the nursing homes in Songjiang District is not satisfactory at present.It is necessary to strengthen the publicity and education of oral health care for the elderly in nursing homes in cooperation with multiple departments to improve their awareness of oral health care including appropriate tooth repair for the quality of life.
ABSTRACT
Objective To investigate the dietary pattern and health status of residents in Songjiang District,Shanghai from 2007 to 2012 and provide basis for nutrition education and nutrition improvement.Methods Data were systemized from "Health and Nutrition Survey among Residents in Shanghai",which was carried out in Songjiang District in 2007 and 2012.Statistical analysis was made on average every standard person daily intake of vrious foods,dietary pattern and change of health status.Results The average every standard person daily intake of cereal foods,fruits,milk,beans and nuts increased as compared with those in 2007,while the intake of vegetables,aquatic products,livestock and poultry meat decreased from 2007 to 2012 in Songjiang District.And the intake of the livestock and poultry meat declined the most (from 137.4 g to78.8 g),that was closer to the recommended intake.Residents''intake of energy and nutients both decreased except dietary fiber and VitC,and the proportion of energy supply with carbohydrates had an increasing trend while the fat for energy supply a rising trend.The prevalence rate of hyperlipidemia,high blood pressure and diabetes for residents aged 15 and above were on the rise.Conclusion The dietary pattern of residents in Songjiang District has been with irrationality and nutrition related diseases such as hyperlipidemia,high blood pressure and diabetes has had a remarkably rising trend.Specific and various nutrition education should be carried out to promote the establishment of rational diet concepts and to improve the residents'' health level.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate in vivo pharmacokinetics of Ophiopogonis Radix polysaccharide MDG-1 oily suspension injection prepared with different prescriptions in rats, and explore the feasibility of the long-acting drug delivery of MDG-1 Injection by using the oily suspension drug release system.</p><p><b>METHOD</b>MDG-1 microparticles were prepared by the anti-solvent precipitation method. Their size and size distribution were characterized. Castor oil with a high viscosity or aluminum stearate were added into soybean oil with a low viscosity, in order to prepare oily media with different viscosities, detect their rheological properties and screen out superior prescriptions for in vivo evaluation.</p><p><b>RESULT</b>The average size of microparticles was 21.81 microm, and the span between them was 2.63. The in vivo evaluation was conducted for prescriptions of mixed oil (soybean oil/castor oil, 2: 3) and soybean oils gelled by 2% and 4% aluminium stearate. Among them, the prescription of soybean gelled by 4% aluminium stearate could significantly reduce C(max) and prolong the apparent t1/2, with the MDG-1 release time of several days.</p><p><b>CONCLUSION</b>It is feasible to achieve the long-acting MDG-1 drug delivery by using oily media with a high viscosity.</p>
