BACKGROUND: Health status of elderly people is an important problem concerned by the whole society. To find the way of preventing loss of functional status of daily life for elderly people is the key to generally improving the quality of life in elderly people.OBJECTIVE: To observe the main characteristics of function loss in healthy elderly people and analyze the influencing factors of the change of functional indexes in elderly people in normal functional status.DESIGN: Contrast observation; Logistic analysis.SETTING: Student's Office, Shangrao Normal College.PARTICIPANTS: All the data were from the sampling questionnaire survey on health status of 1 700 people including retired cadres and employees from 11 cities of Jiangxi province. The survey was conducted by Senile Physical Education Association of Jiangxi Province in January 2004.METHODS: The test was performed depending on 4 indexes in physical self-maintenance scale including dressing, taking food, bathing and toileting along with other indexes of shopping, calling, riding, going upstairs to the third floor, walking for 1 000 m, taking things by fingers and squatting & standing. These 11 indexes were used for evaluating the functional status of daily life in elderly people. According to international definition,people with difficulty in one or more indexes could be defined as ability loss of self-cave in daily life. The participants were demanded to give the score of difficulty in independently completing each activity including not difficult (1), somewhat difficult (2), very difficult (3), completely impossible (4). The total sum of 11 scores was defined as functional status index of daily life. Its value reflected the whole situation of functional status of daily life in elderly people. The higher the index was, the worse the functional status was. Comparison was conducted among groups of different gender and age, and Logistic regression analysis was used for evaluationand analysis.MAIN OUTCOME MEASURES: Evaluation of functional index, function loss rate of daily life, index in independent physical self-maintenance ability of daily life.RESULTS: ① Normal functional status of elderly people is various due to the different age, gender, constitution, marital status, living situation,employment history, economic status and education background etc. ② As far as function loss rate of daily life in healthy elderly people was concerned, male was higher than female, and people taking part-time jobs and rehired after retirement were higher than other retirees. When it came to loss rate of motor function of lower limbs, widowed people were higher than not widowed, and the higher the education, the better motor functional status of lower limbs the male had, while the situation was reversed for female.CONCLUSION: Loss rate of normal functional status of elderly people significantly decreases as their age increases, and it is relevant to the complexity and difficulty of activities of life. Normal functional status of elderly people is related to social support, economic status, psychological and mental status.

In recent years, the issue of liabilities in state-owned medical institutions in China has come to the attention of departments at different levels and has become one of the top concerns of various government departments and hospital administrators. Defining the appropriate scope of liabilities ratio for hospitals has become an urgent task in ensuring their unconventional and sustainable development from a high starting point and at a fast pace. On the basis of relevant financial theories and in light of the current situation of the domestic medical market and characteristics of state-owned hospitals, the paper makes a case study of the liabilities ratio of hospitals in a certain region so as to explore the appropriate scope of liabilities ratio and the scale of liabilities for hospitals.

Fifty-two patients exactly diagnosed as rheumatoid arthritis in the active stage in clinic were treated by acupuncture plus western medicine. Thirty days made up a course of treatment. There were significant differences in clinical symptoms, signs, and immunological indexes between pretreatment and posttreatment (P<0.05, P<0.01). The treatment of rheumatoid arthritis in the active stage by acupuncture plus western medicine could effectively regulate humoral immunity and enhance the clinical therapeutic effect.

Calli were induced from young leaves,immature seeds and hypocotyl of Swertia mussotii Franch.Three kinds of media,MS,B5 and N6 were set up in the experiment. Calli were established with the highest frequency on to MS medium cantaining 3mg/L 2,4-D and 0. 6mg/L KT.The induction antmaintenence of the calli were affected markedly by the basic media and compound 2,4-D and KT in the media which proved that asextual reproduction of S. mussotii is possible by tissue culture

Objective To analyze and discuss the effect of heat preservation on the recovery time of BIS and the concentration of propofol in the recovery period of the elderly patients with general anesthesia in order to provide guidance for clinical treatment.Methods 78 elderly patients with general anesthesia were selected as the subjects, and the patients were divided into the control group and the study group with 39 cases in each group.The patients were divided into the control group and the study group.Control group, only to be liquid input and covered by drapes, research group take liquid input and peritoneal flushing fluid heating and heating blanket coverage of insulation measures, were recorded and compared between the two groups from anesthesia began to operation to complete the different time points of esophageal temperature and MAP, and to observe the recovery time of patients and effect compartment concentration differences.Results Two groups at T0, T1 esophageal temperature no significant difference, study group T2-T6 esophageal temperatures were significantly higher than those of the control group (P<0.05), maps of the other two groups at different time points had no significant difference;when two groups of patients with propofol withdrawal BIS values had no significant difference, and in the time of discontinuation BIS is more than or equal to 80 recovery time and effect compartment concentration have significant difference (P<0.05).Conclusion The surgical treatment of elderly patients with general anesthesia can help maintain the body temperature, shorten the recovery time of BIS and reduce the concentration of propofol in the recovery period.

Vascular endothelial growth factor (VEGF),platelet derived growth factor (PDGF) and complements play key roles in the pathogenesis of age-related macular degeneration (AMD).Pegaptanib,the first therapeutic aptamer against VEGF165,has been approved by the Food and Drug Administration (FDA) of US for the treatment of exudative AMD.Another two aptamers El0030 and ARC1905,each target PDGF-B and complement C5 respectively,are undergoing clinical trials.Recent trends to treat AMD are combined therapies targeting multiple key molecules in the pathogenesis of AMD;aptamers against multiple targets may become the preferred drug for AMD.

Objective To investigate the reasons of complications after ultrasound-guided PTBD and explore measures for their management. Methods The clinical data of 753 patients with obstructive jaundice treated with ultrasound-guided PTBD in our hospital from January 2001 to June 2008were retrospectively analyzed. Results The 753 patients received a total of 791 treatments of PTBD.The occurring rates of severe, common, and long-term complications were 1.14 % (9/791), 11.88 %(94/791 ) and 4.3% (9/791), respectively. Only 1 patient died of manipulation-related complications.Conclusion Ultrasound-guided PTBD is an effective method for treatment of obstructive jaundice.

Objective To observe the change of peripheral blood Th17 cells and relationship between the severity and Th17 cells in patients with acute asthma.Methods We recruited patients with mild acute asthma(n=10) and severe acute asthma(n=10), and healthy volunteers(n=10). T-lymphocytes were collected from the peripheral blood mononuclear cells (PBMC). Flow cytometer (FCM) was used to detect the expression of peripheral blood Th17 cells. IL-17 levels in the peripheral blood were measured by enzyme-linked immunosorbentassay (ELISA).Results The rate of positive Th17 cells of peripheral blood in the severe acute asthma group was higher than that in the mild acute asthma group(P＜0.05) and the rate of positive Th17 cells of peripheral blood in healthy volunteer group were the lowest among all groups (P＜0.05, respectively). The level of IL-17 in the peripheral blood of patients with severe acute asthma increased significantly compared with that in patients with mild acute asthma and healthy volunteers (P＜0.05). The positive Th17 cells of peripheral blood in patients with acute asthma were positively correlated with the severity of acute asthma(r=0.869, P＜0.05).Conclusion The positive rate of Th17 cells in the peripheral blood increases in patients with acute asthma and has positive correlation with the severity of acute asthma.

In this study, the effect of prophylactic anti-inflammation on the development of smoke-induced emphysema was investigated. Young male guinea-pigs aged 1.5-2 months (weighing 198.3+/-26.9 g) were randomly divided into 4 groups: group A (cigarette smoke exposure only), group B (cigarette smoke exposure plus pentoxifylline-rich (PTX, 10 mg/d) forage feeding), group C (cigarette smoke exposure plus intermittent cortical steroid injection (Triamcinolone acetonide, 3 mg, i.m., every three weeks) and control group (group D: animals with sham smoke exposure, raised under the same conditions). Animals in group A, B and C were exposed to smoke of cigarettes for 1 to 1.5 h twice a day, 5 days a week. All animals were killed at the 16th week and followed by morphometrical analysis of the midsagittal sectioned lung slices. Smoke exposure of 16 weeks resulted in visible emphysematous development in Group A but not in Group B and C. It was evidenced by the indicator of air-space size, mean linear intercept (Lm): 120.6+/-16.0 microm in Group A; 89.8+/-9.2 microm in Group B and 102.4+/-17.7 microm in Group C. The average Lm in either group B or group C was shorter than that in Group A (ANOVA and Newman-Keuls test, F=8.80, P=0.0002) but comparable to that (94.8+/-13.2 microm) in group D (P>0.05). It is concluded that long-term prophylactic anti-inflammation inhibits pulmonary emphysema induced by cigarette smoking in the guinea pigs.
