Aim To study mechanisms of Stigma Maydis Polysaccharide(SMPS) on weight loss in experimental animals. Methods Observe changes of gastric discharge, intestinal peristalsis, biliary secretion, weight of gallbladder, body weight, appetite and cholecystokinin(CCK)level in plasm of rats and mice after being administrated with SMPS. Results SMPS increased the gastric residual rate of methyl orange and the intestinal propulsive rate,advanced first time black dejecta,increased the quantity of dejecta,decreased the weight of gallbladder in mice. SMPS also inhibited appetite,decreased body weight,prolonged gastric emptying,accelerated the propulsion speed of intestinal contents,promoted the biliary secretion,increased CCK level in plasm. Conclusion Mechanisms of weight loss are probably related to the increasing of CCK level in plasm and prolonging of gastric emptying,appetite inhibition, accelerating of intestinal peristalsis,the quantity increasing of dejecta.

OBJECTIVE:To observe the influence of Valsartan on the serum ET,CGRP levels,urinary protein and Q - Td of patients with CRF complicating hypertension.METHODS: CRF research group including 24 patients with CRF complicating hypertension receiving Valsartan 80mg/ d for 4 weeks; CRF control groups including 20 CRF patients with normal blood pressure; health group including 9 health people.The serum ET and CGRP levels, urinary protein, and Q - Td were measured.RESULTS: (l)The serum ET level of CRF patients was higher than that of health people;The serum ET level of CRF research group(before treatment) was higher than that of CRF control group and decreased after treatment of Valsartan.(2) The serum CGRP level of CRF patients was higher than that of health people .The serum of CGRP level of CRF research group (before treatment) was higher than that of CRF control group and continued to increase after treatment of Valsartan. (3) The content of urinary protein of CRF patients was significantly higher than that of health people.The content of urinary protien of CRF research group before treatment was higher than that of CRF control group and decreased after treatment of Valsartan. (4) The Q - Td of CRF research group was longer than that of health group and CRF control group.But the Q - Td of CRF research group did not change after treatment of Valsartan.CONCLUSION: Valsartan could effectively control blood pressure and decrease content of urinary protein, and delay the deterioration of renal function, but could not reverse the cardiovascular remoulding.

Objective To survey the social support status and demands for family caregivers of the disabled elderly.Methods A cross-sectional survey based on convenience sampling was conducted among 779 disabled elderly and their family caregivers from May to June 2013 in five communities of Beijing Dongcheng District.Barthel index was used to measure the degree of functional impairment of the elderly.Self-rating Depression Scales (SDS) was used to evaluate depression symptoms of caregivers.Social Support Rating Scale (SSRS) and social support demand questionnaire were used to measure the social support status and social support demands of caregivers,respectively.Multiple linear regression analysis was used to analyze the influence factors of social support.Results Total 779 caregivers were identified and 744 caregivers completed the questionnaires with a valid response rate of 95.5％.Among 744 family caregivers the social support levels were low with an average SSRS score of 31.16 ± 6.86.There were significant differences in SSRS scores among caregivers of disabled elderly with different characteristics (age,married status and the Barthel index score) (all P ＜ 0.05);and there were significant differences in SSRS scores among caregivers with different characteristics (age,educational level,married status,current employment,relationship with patients,caregiving time daily,subjective care burden,living with patients,number of caregivers and depression status) (all P ＜ 0.05).Multiple linear regression analysis showed that the Barthel index score of the disabled elderly,the relationship with the elderly,depression status of the caregivers and the subjective care burden were correlated with the social support level of family caregivers (all P ＜0.05);the standard regression coefficients of above significant factors were 0.098,0.190,0.134 and 0.155,respectively.The social support demands of family caregivers were various;the average score was 2.44 ± 0.64,the top three demands were provision of care subsidy for the disabled elderly (average score was 2.95 ± 0.93),provision of care allowance for family caregivers (average score was 2.90 ± 0.93) and the guidance of safe medication (average score was 2.83 ± 0.83).Conclusions Family caregivers for the disabled elderly obtain low level social support in the surveyed area.Since the earegivers have various social support demands,the social support and assistance for them should be specific,effective and comprehensive.

Objective To investigate the effect of community comprehensive intervention on health behavior and self-rated health status among family caregivers of disabled elderly.Methods One hundredand twenty family caregivers of disabled elderly were selected from community health service centers of Beijing Dongcheng District,and were given 6 month-comprehensive community intervention (intervention group);121 family caregivers of disabled elderly from another community were selected as the control group.The knowledge and skills of caregiving,health behaviors (daily exercise time,daily relaxation time) and self-rated health status were evaluated before and 6 months after intervention.Results The knowledge and skill scores in intervention group were improved by 50.781 points,the daily exercise time and daily relaxation time were prolonged by 0.491 h and 0.837 h,respectively after the intervention (all P＜0.05).There was no significant difference in self-rated health status of two groups before and after intervention (P ＞0.05).Conclusion Community comprehensive intervention improves the knowledge and skills of caregiving,and the health behaviors among family caregivers of disabled elderly,but the intervention measures does not impact the self-rated health status of family caregivers.

Objective:To study the effects of 1?,25-dihydroxyvitamin D 3 and UVB on cell proliferation and melanin synthesis of normal human melanocytes. Methods:Melanocytes of foreskins of healthy men were cultured and treated with various concentration of 1?,25-dihydroxyvitamin D 3 or UVB (55 mJ/cm 2),or both.Cell proliferation was measured with MTT assay .The synthesis of melanin was determined by chromatography. Results: 1?,25-dihydroxyvitamin D 3 and UVB could promote the proliferation of cultured melanocyte,and 1?,25-dihydroxyvitamin D 3 could promote the melanin synthesis.The significant concentration of 1?,25-dihydroxyvitamin D 3 ranging from 10 -7 to 10 -10 mol/L.Conclusion:1?,25-dihydroxyvitamin D 3 and UVB irradiation could promote the proliferation of melanocyte,which indicates that they might be effective in the treatment of vitiligo.

Objective To study the effects of endothelin-1 (ET-1) and adrenocorticotropic hormone (ACTH) on the proliferation of cultured normal human melanocytes. Methods Normal human melanocytes were obtained from the foreskins of healthy men, and cultured in minimum essential medium (MEM) with 10% bovine serum. The cultured melanocytes of the 3rd passage were treated with various concentrations of ET-1 and ACTH. Cell proliferation was assessed by the MTT method. Results ET-1 (0.1 ~ 1 000 nmol/L) promoted the proliferation of cultured human melanocytes. ACTH (10-13 ~ 10-9 mol/L) also promoted the proliferation of cultured human melanocytes (P

Objective To analyze the falls of female inpatients with the psychotics diseases and summarize effective nursing intervention. Method Two hundred and eighty-nine psychiatric female inpatients from April 2014 to August 2014 were collected, and the reasons of falls cases during this period were analyzed and nursing methods were formulated. Result Nine patients fell, with an incidence of 3.11%(9/289) including the reason of lack of risk dynamic evaluation, lack of fall prevention measures and shortage of nursing personnel. Conclusions The reasons for the falls of the hospitalized psychiatric female patients include lack of risk dynamic evaluation, lack of fall prevention measures, shortage of nursing personnel. The nursing countermeasures include risk assessment of dynamic management and the implementation of the fall prevention measures , strengthening training and health education so as to prevent and reduce the occurrence of falls and ensure patients'safety.

Objective To explore the effects of angled abutments on the anterior maxilla implant restoration. Methods We analyzed the biomechanical properties of implants of different sizes (Φ3.5 mm,4.0 mm and 4.5 mm in diameter;L11.5 mm and L13 mm in length)after connecting different angled abutments (0°,10°,20°,and 30°) using finite element method.Results The stresses and strains of loading parts of restorations increased and their distribution became more concentrated as the angle of abutment increased.Cortical bone of Φ3 .5 implants with smaller angle (10°or less)andΦ4.0 implants with abutments had the risk of overpassing the bone elastic threshold when the angle approached 30°.However,the cortical bone elastic deformation was within a safe range at all angles inΦ4.5 group.Conclusion We should consider the diameter of the implant when selecting angled abutments.The angled abutments are not suitable for small diameter implants.The bite force should be under control when needed. The larger angled abutments can be applied in the standard and major diameter implants and it is necessary to avoid occlusal overloading.

Objective To explore the relationship between care burden and social support among family caregivers of disabled elders in Beijing urban area.Methods A cross-sectional survey based on convenience sampling was conducted among 744 family caregivers in Dongcheng District in Beijing urban area.All subjects were interviewed by the Zarit Burden Interview (ZBI),Social Support Rating Scale (SSRS) and general social and demographical material lists.And then we analyzed the correlation between social support and care burden.Results The mean scores of ZBT and SSRS were (40.3 ± 15.2) and (31.1 ± 6.9)respectively.And a negative correlation existed between the level of caregiver burden and total social support.The care burden of disability elders was negatively associated with objective support,subjective support and social support availability (P ＜ 0.05).Conclusions There is a close relationship between care burden and social support among family caregivers of disabled elders.The more objective support,subjective support and social support availability the caregivers acquire,the less burden they bear.
