Objective To assess the feasibility of secondary check by LinaTech TiGRT treatment planning systems.Methods Choosing the Linatech TiGRT treatment planning system,researched and developed by Linatech company,as the third-party check tools.First,using Linatech TPS for recomputing treatment plans for geometrical phantoms designed in TG-119 and patients.after computation,compared the point dose with the measured data of phantoms (Using chameber No.2571 to measure point dose) and original plans.Using PTW verisoft with a criteria of 3% dose difference and 5 mm distance to agreement to assess the dose distribution on center level.After then,you can assess the accuracy of treatment plans.Results Tiny volume changes were found in ROI,especially in small size phantoms orcuspidal regions.For comparing measured data with recomputed plans and original plans,the dose data were found basically identical in TG-119 phantoms.And for patients,the differences between recomputed plans and AAA original plans or AXB original plans were smaller in breast cancer,but they were even bigger innasopharynx cancer,all patient cases showed a gamma passing rate more than 90%.The gamma passing rate of AAA original plans and AXB original plans were 95.6% and 97.53% for breast cancer,and 94.67% and 96.83% for nasopharynx cancer.Conclusions The method of utilizing the LinaTech TiGRT treatment planning system as a third-party check tools to assess the accuracy of plans is feasible,and the validation process is convenient,but some functions still need to improve and the scope of differences still need more patient cases to determine.

Objective To investigate the malnutrition status among the elderly in age care institutions in Shanghai suburb and analyze its potential influential factors.Methods The MiniNutritional Assessment (MNA) was adopted to evaluate the nutritional status of the 190 elderly people in age care institutions.The dietary supply by the institution canteen and the quantity of residual food left by the malnourished elderly people were weighted.Results In the age care institutions,the malnutrition rate reached 23.7％,47.9％ of the elderly people were at the risk of malnutrition,and only 28.4％ of the elderly people were well nourished.Logistic regression analysis showed that the major influential factors for malnutrition in the elderly people were food intake ability,mobile capability,chewing and swallowing ability,ageing and mental Illness.The malnourished elderly people had the most residual meat and vegetables,and insufficiency of nutrient intake was the main cause for the malnutrition in the elderly people.Conclusions The elderly people in age care institutions in Shanghai suburb have the higher risk of malnutrition.The malnutrition occurs under influence of many factors,of which some are unavoidable,however,some factors like dietary factors can be changed to improve the nutritional status of the elderly people in age care institutions.

To investigate the immunological activities of the recombinant human phosphatase D2 (rhPLD2) in vitro and in vivo, especially its ability to reduce inflammatory reactions, the cDNA fragment encoding rhPLD2 was cloned into prokaryotic expression vector pET30a by RT-PCR and the recombinant protein rhPLD2 expressed in E.coli was purified from the inclusion bodies, while the anti inflammatory activity of rhPLD2 was determined by the amount of eosinophils in bronchoalveolar fluid(BALF) and blood and the expression of IL-5 and MMP-9 in lung tissues of guinea pig model of chronic asthma. It was found that the rhPLD2 recombinant protein was obtained from human Daudi cells by cloning to E.coli, which contained no membrane-binding site and signal peptide. The cDNA sequence encoded 631 amino acid residues (GenBank Accession Number: AY178289). The purity of the rhPLD2 approached up to 76% with a bioactivity of 50.9745 units/L (0.9212 g/L). In addition, the anti inflammatory effect of rhPLD2 protein could be demonstrated in the guinea pig model of chronic asthma after treatment with rhPLD2 protein, such as down regulation in the expression of the inflammatory cytokine IL-5. It is concluded that the anti-inflammator activity of the recombinant human truncated PLD2 protein produced from the E.coli plasmid can be demonstrated both in vitro and in vivo.

Objective This study evaluated the effects of combined procedure of surgical treatment and cell transplantation on dilated cardiomyopathy. Methods Eight patients (5 men and 3 women) with moderate to severe mitral regurgitation from end-stage dilated cardiomyopathy underwent surgery. Four patients were in functional class (FC) Ⅳ, six were in FC Ⅲ. There age ranged from 15 to 56 years. The preoperative ejection fraction (EF) ranged from 0.15 to 0.32 (mean 0.26 ± 0.08). Mitral valve replacement was performed in 5 patients and mitral valve repair in 3. Auto-bone marrow monenuclear cells were harvested, isolated, washed, and resuspended for direct injection after surgical procedure. Results All patients survived and were discharged from the hospital. After a mean follow-up period of 18 months ( 12 - 42 months). Echocardiography showed postoperative ejection fraction and wall movement velocity increased after 6 months. Radionuclide ventriculography showed myocardial perfusion improved significantly. Conclusion Combined procedure of surgical treatment and cell transplantation led to significant improvement in cardiac function in patients with dilated cardiomyopathy.

Objective To explore the distribution and localization of LPGDS (Lipocalin-type prostaglandin D synthase) in rat testis and epididymidis and gain further insight into LPGDS potential function in male reproduction. Methods The expression of LPGDS in rat testis and epididymidis was assessed using RT-PCR and immunobloting. Using immunohistochemistry to explore the distribution of LPGDS in rat testis and epididymidis. Results None of the LPGDS studied was present in the testis of 2 month old SD rat. LPGDS was strikingly expressed in the caput epididymidis, while moderate to weak expressing was observed in the corpus and cauda epididymidis. The result of immunohistochemistry displayed that LPGDS was mainly localized within the cytoplasm and the cilia of the epithelial cells in rat epididymidis. Conclusion LPGDS was mainly distributed in epididymidis and localized with in the cytoplasm and the cilia of the epithelial cells. There was no LPGDS expressed in the testis of 2 month old SD rat, but it was strikingly expressed in the epididymidis, and the dose of expression was different, which suggested that LPGDS may play some kind of role during the process of the spermatozoa maturation.
