Objective To evaluate the preoperative nutritional status of patients with gastric cancer by using patient-generated subjective global assessment (PG-SGA) its relationship with postoperative results.Methods Make a preoperative nutrition assessment by using PG-SGA for 87 patients with gastric carcinoma who can be treated with operation.Analyze the effects of the postoperative complication,survival rate and the hospitalization time on patients.Results The number of patients of this group who can process the preoperative nutrition assessment by using PG-SGA accounts for 100％ of the total.There are 37 patients with moderate or severe malnutrition before operation (account for 39.1％).The complication incidence of patients with moderate or severe malnutrition before operation and the patients with no or mild malnutrition are 52.9％ and 5.7％ separately (P ＜ 0.01).The sensitivity and specificity of PG-SGA score for predicting complications are 85.7％ and 75.8％ respectively.And we should implement the analysis of regression to verify that the PG-SGA grade is the independent risk factor of postoperative complication by applying multiple Logistic(P ＜ 0.01).The average hospital stays of patients with moderate or severe malnutrition before operation and the patients with no or mild malnutrition are (21 ± 6) d and (16 ± 4) d separately (P ＜ 0.01).Conclusion According to the PC-SCA results,patients with moderate or severe malnutrition before operation have increased susceptibility to complication and the extension of hospital stays after the operatiou.Therefore,it is important to supply the proper nutrition support to these patients.

Objective To evaluate the sensitivity and specificity of plain radiography in the diagnosis of vascular calcification in maintenance hemodialysis (MHD) patients. Methods Multi-slice computed tomography (MSCT) was used as the reference standard in the assessment of vascular calcification in MHD patients. A total of 54 MHD patients, 26 male and 28 female, mean age (60.4±13.3) years, underwent both MSCT and plain radiography of lateral abdomen and pelvis to evaluate abdominal aortic calcification, bilateral iliac and femoral artery calcification. Abdominal aorta was divided into upper and lower segment by L2-L3 intervertebral space. The severity of vascular calcification by MSCT was graded from score 0 to 5. Two independent radiologists analyzed the results of plain radiography and MSCT, and inter-observer agreements were calculated by using K statistics. Results According to the results of MSCT, the calcification rate of abdominal aorta was 86.1%, and the calcification rate of iliac and femoral artery was 74.5%. There was significant difference of the calcification rate between large artery and muscular arteries. Inter-observer agreement of calcification was excellent (K =0.864-0.893). Compared with MSCT, the specificity of plain radiography with regard to detection of abdominal aortic, iliac and femoral calcification were 100%. The sensitivity of plain radiography was different according to the different MSCT score, which was as follows: MSCT score ≥ grade 1: 60.2% and 24.8% for lateral abdomen radiography to detect abdominal aortic calcification and pelvic radiography to detect iliac, femoral calcification respectively; MSCT score ≥ grade 2: 76.9% and 43.5% respectively; MSCT score grade 3: 100% and 74.4% respectively. Conclusions The sensitivity of plain radiography in the assessment of vascular calcification increases with the severity of calcification. The sensitivity in the assessment of abdominal aortic calcification is higher than that of iliac and femoral artery calcification. Plain radiography can be used to detect moderate to severe vascular calcification in MHD patients.

OBJECTIVE:To provide reference for promoting the development of related legislation work on ensuring pediatric drug use in China. METHODS:The legislation process of pediatric drug use in US,the effects of current Best Pharmaceuticals for Children Act and Pediatric Research Equity Act on pediatric drug use in US were intrduced and analyzed,suggestions on guarantee-ing the accessibility and safety on pediatric drug use in China were put forward. RESULTS & CONCLUSIONS:The policy6-month period of pediatric exclusive protectionin Best Pharmaceuticals for Children Act has motivated the enthusiasm of phar-maceutical companies developing pediatric studies,while it affects the marketing of generic drugs. Pediatric Research Equity Act has achieved remarkable effect in terms of ensuring the safety of pediatric drug use by forcing pharmaceutical companies to carry out pediatrics assessments,while there is no enough force for the marketed drugs that has not been widely used for children. En-couragement and enforcement are useful methods for promoting development of pediatric drug use. It is suggested to take measures like modifingone drug two formsin Prescription Management Regulations,accelerating approvals of related pediatric drugs on the premise that safety is guaranteed,implementing tax preference for related pharmaceutical companies that produced pediatric drugs,promoting the entry of drug reimbursement list and empowering CFDA to force pharmaceutical companies to implement pedi-atric studies to promote the accessibility and safety of pediatric drugs.

BACKGROUND:Pulsed laser deposition synthesis technology has been used to prepare new nano-hydroxyapatite thin film coating by colagen deposition on artificial mechanical heart valve. OBJECTIVE: To investigate the toxicity of new nano-hydroxyapatite thin film on human umbilical vein endothelial cels. METHODS: Human umbilical vein endothelial cels were cultured with nano-hydroxyapatite film room-temperature leaching solution, nano-hydroxyapatite film high-temperature leaching solution, high-density polyethylene and phenol solution. Within 72 hours, cel growth was observed under the inverted phase contrast microscope. At 7 days after culture, cel proliferation and toxicity grading were detected using Cel Counting Kit-8. RESULTS AND CONCLUSION:At 24 hours after culture, cels grew wel, showed fusiform shape, and had strongrefraction in the nano-hydroxyapatite film room-temperature leaching solution, nano-hydroxyapatite film high-temperature leaching solution, high-density polyethylene groups, and no significant differences in cel morphology and number were detected among above groups. Cels in the phenol solution group were suspended, round, pyknotic and dead. At 48 hours, except phenol solution group, cel number increased significantly, and cel grew densely in other three groups. At 72 hours, cels grew strongly, and the gap became smal obviously. Within 7 days after culture, cel proliferation activity was not significant in the nano-hydroxyapatite film room-temperature leaching solution, nano-hydroxyapatite film high-temperature leaching solution, and high-density polyethylene groups, which was significantly higher than in the phenol solution group (P < 0.05). The toxicity of nano-hydroxyapatite film graded 0 to 1. These results suggested that nano-hydroxyapatite artificial mechanical heart valve has good histocompatibility, but no toxicity.
