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.

Surgery for gastric cancer is based on basic surgical techniques and modern theory of surgery.Accurate and safe surgical procedures are carried out based on application of scientific principles.The knowledge of gastric anatomy,physiology and pathophysiology is the basis of the gastric cancer surgery.The technical aspects of vascular control,lymph node dissection,digestive tract resection and reconstruction are important for the gastric cancer surgery.Full use of these techniques and mastery of the technology is an important guarantee for reducing surgical complications,improving the quality of life and longterm survival of gastric cancer patients.

ObjectiveTo express and purify glutathione S-transferase(GST) and midkine(MK) fusion protein and prepare the ployclonsl antibody against MK.MethodsThe coding sequence of MK gene was amplified by RT-PCR from human gastric cancer tissue and inserted into pGEX-1λT vector.The recombinant vector was transformed into E.coli.BL21 ( DE3 ) to express the fusion protein GST-MK via IPTG induction.The expressed fusion protein was purified by GST affinity system and used to immunize rabbits for preparing the ployclonal antibody against GST-MK.ResultsThe expression vector pGEX-MK was constructed successfully.The expressed fusion protein was obtained by GST affinity system.The titer of the polyclonal rabbits antiserum was 1 ∶ 64 000 by indirect ELISA,Western blotting analysis showed that the antibody specifically bind to MK.ConclusionThe expressed protein and prepared polyclonal antibody provided useful reagents for MK further reaserch.

Resection of the automonic nervous system in the process of lymph nodes dissection is a major factor leading to postoperative gastrointestinal dysfunction.The era of blind expansion of the wide excision has been questioned,and safety first,radical dissection of the metastatic lymph nodes,low invasive rate and organ function-saving surgery have been highly emphasized.Preserving the gastric autonomic nerve effectively reduces postoperative diarrhea,shortens the time for weight recovery,and prevents insulin secretion disorders and postoperative cholelithiasis.In the process of laparoscopic or open autonomic nerve preservation in lymph node dissection for gastric cancer,full understanding of the anatomy of the autonomic nervous system,recognizing the landmark of the nerves,proper designing the surgical space,dissecting according to the extracellular space in the membrane of the nerve fibers and nerve plexus are factors which ensures the quality and effects of the surgery.

Toll like receptors(TLRs) , a pattern conservative receptor superfamily are found on mammalian cell surface over the last decade. TLRs recognize distinct pathogen - associated molecular patterns, which can lead not only to the responses of the innate immunity but also to the development of the antigenspecific adaptive immunity. The expression of TLRs have changed in some carcinomas, besides, microbial composition and drugs mediate the tumor immunotherapy by the way of TLRs signal transduction. Consequently , deep studies on TLRs will provide new approaches for tumor immunotherapy.

Tumor marker is a hot subject of research in oncology field,which would promote the diagnosis and treatment in clinic.Tumor markers of children's germ cell tumor include α-fetoprotein,glypican 3,SALL4,glial cell line-derived neurotropic factor receptorα-1(GFRα-1),Ki-67,octamer-binding transcription factor4,CD117,D2-40 and CD30.SALL4 would be used as a new tumor marker for germ cell tumor,specially for yolk sac tumor.GFRα-1 can be helpful for the diagnosis of immature teratoma.

Stage Ⅳ gastric cancer is defined as gastric cancer with non-curative factors,and the long-term survival rate of patients with stage Ⅳ gastric cancer is around 10％.Chemotherapy has been used for the main therapy of the patients with unresectable stage Ⅳ gastric cancer.Palliative resection of the primary tumor has been recommended only for presence of obstruction,bleeding and other surgical emergency.Debulking operation was irrelevant to the outcome that has been considered by research results.However,the patients with stage Ⅳ gastric cancer of only one non-curative factors (No.16a2,b1 lymph node enlargement;degree of peritoneal metastasis as P0 and positive peritoneal cytology;a small number of liver metastases)have good long-term survival when these patients have achieved R0 or R1 resection.In this regard,comprehensive treatment including surgical resection is the main treatment policy for the patients with stage Ⅳ gastric cancer.In recent years,some clinical studies on improvement of prognosis through surgical resection after conversion therapy have received extensive attention.
