Objective　To explore the metabolism of micronutri ents related to dark adaptation of radar operators through nutritional intervent ion. Methods　A total of 34 male radar operators aged between 18 ～29 years old were randomly divided into control and experimental groups. The c ontrol group were on normal diet, and the experimental group received the supple ment of VA, Zn and Se in additional to normal diet. The experiment lasted 4 week s. The levels of serum VA, Zn and Se were measured before and after the experime nt. Results　The levels of serum VA, Zn and Se in the experime ntal group were significantly higher than that in the control group after the experiment (P<0.01). Conclusion　The supplement of VA, Zn an d Se for 4 weeks may elevate, the levels of serum VA, Zn and Se significantly (reached or surpassed normal levels) and suggests that VA, Zn and Se su pplementation may effectively enhance the dark adaptation of radar operators.

Objective Through retrospective analysis of the thoracotomy of pulmonary metastases form osteogenic sarcomas in order to explore the related factors of prognosis and to improve the outcome of treatment.Methods From October1980to March2003,32cases with pulmonary metastases from sarcoma of bone were reviewed.62of thoractomy were performed for the patients,61of which were accomplished in the department of orthopaedics,and58operations were performed by the authors.There were32males and10females aging from11to61years with an average of 22.1years.The primary tumors of the patients were25oateosarcomas,3chondrosarcomas,2juxtacortical osteogenic sarcomas,and1each of fibrosarcoma and Ewings sarcoma.Of 32cases,21(65.6%)were treated with limb salvage,and11(34.4%)by am puta-tion.According to Enneking system,there wereⅡB in26andⅢB in5.25(78.1%)cases were bi lateral multiple metastases,6(18.8%)cases were unilateral solitary metastasis,and1(3.1%)case was unilateral mul tiple metastases.Most of the procedures of operation were local resection of the tumor ;however,only5cases underwent lobectomy.Results The postoperative complications included1case of severe bleeding cured by exploratory thoracotomy,2cases of lethal infections,and1case of atelectasis.Of 32cases,11sur -vived with out tumor at final follow-up.In25osteosarcoms,16were dead,2were lost from the follow-up;7cases of the other18cases that bilateral resections performed,were alive without tumor (38.9%)with a me di an survival time of 7years and3months.1each of Ewings sarcoma,paraosteal osteosarcoma and,chon-drosarco ma survived without tumor for 22years and5months,19years and3months,and13years and3months respectively.Conclusion Thoracotomy of pulmonary metastases of osteogenic sarcomas is an ef-fective method to salvage the patients life.The procedure of metastasectomy is local resection.The results al-so suggest that newadjurant chemotherapy is a important way to effect the condition of pulmonary metastases of osteogenic sarcomas.

[Objective]To evaluate the accuracy and value of CT guided biopsy of bone lesion.[Method]A total of 137 cases of CT guided biopsy were analyzed,including 1 case of cervical vertebrae,22 cases of thoracic vertebrae,47 cases of lumbar vertebra,8 cases of sacrum,9 cases of pelvis,2 cases of scapula and 48 cases of extremities.The biopsies were completed in local anesthesia under CT guidance,using trephine needle or Tru-cut needle.[Result]The puncture accuracy was 100%,the general diagnostic accuracy was 89.0%(122/137),in which the diagnostic accuracies of metastasis lesion,primary bone tumor and benign lesion were 95.8%(46/48),85.7%(36/42)and 85.1%(40/47)respectively.[Conclusion]CT guided biopsy was a safe and accurate method with little trauma and complication,having great value in deciding treatment of bone lesions.

[Objective]To evaluate the operability and clinical efficacy of injectable calcium sulfate for grafting bone defects.[Method]From June 2004 to August 2005,22 cases with benign bone lesions were treated with curettage and grafting with injectable calcium sulfate bone graft substitute(minimally invasive injectable graft X3,MIIG X3).There were 13 male cases and 9 femal cases.Their average age was 34.6(ranged,4~55).All the 22 cases were followed-up from 23 months to 37 months,average 31.6 months.All cases took radiographic examination regularly after the operation to assess the absorption rate of MIIGX3 and the formation rate of new bone.[Result]This injectable calcium sulfate with vacuum mixing was easy to use,providing complete fill and bony strength instantly when grafting bone defects.According to the raeiographs,MIIGX3 was absorbed almost at the same rate as new bone ingrowth in 8 to 24 weeks.[Conclusion]MIIGX3 is convenient to graft bone defects with fewer complications,capable of absorbing almost at the same rate as replacement of new bone.It's one of the best bone graft substitutes for grafting bone defects induced by benign bone lesions.

Objective To investigate the molecular mechanism of Klebsiella pneumoniae resistant to carbapenem. Methods The minimal inhibitory concentrations ( MICs) of the antimicrobial agents were determined by E-test. The 23 β-lactamase genes and 2 porin genes were amplified by polymerase chain reaction (PCR) , then the products were purified and their sequences were analyzed. Results The MICs of piperacillin, piperacillin/sulbactam, amoxicillin/clavulanic acid, cefoperazone/sulbactam, cefotaxime, cefepime and aztreonam to 5 strains of Klebsiella pneumoniae were all higher than 128 μg/mL, and those of imipenem or meropenem were higher than 32 μg/mL. All isolates carried blaTEM-1 and blaDHA-1 genes. Deletion of ompK35 and ompK36 were observed in Kp01 and Kp03, and the deletion of ompK35 was also observed in Kp02 and Kp05. Base insertion of ompK36 occurred in Kp02, Kp04 and Kp05. Compared with GenBank (GU945384) , ompK35 gene mutations of G→C at base 465 and T → C at base 466 in Kp04 lead to Gln to His substitution at position 155 and Tyr to its substitution at position 156, and it might be a new subtype. Conclusion The production of DHA-1 β-lactamase combined with the loss of OmpK36 or OmpK35 in porin genes may contribute to high-level carbapenem resistance in Klebsiella pneumoniae.

Objective To analyze the implementation effect of formative assessment in nutri-tion and food hygiene. Methods 55 students of Class One from grade 2010 majoring in preventive medicine were taken as the control group, with 56 students of Class Two as the experimental group.The control group used the summative assessment , while the experimental group used the formative assessment. Results were analyzed by course examinations and questionnaire surveys. SPSS 17.0 soft-ware was used and the measurement data were expressed by x±s. Statistical analysis was performed using t test, test, rank sum test, a Yuan linear correlation analysis, with the level of test α=0.05. Results The experimental scores and final scores of experimental group students were significantly higher than the control group and the difference was statistically significant(P values were 0.001, 0.000). The experimental group's overall result is closer to the negative skewed distribution. The ex-perimental group's average score of 89 points is significantly higher than the control group's average score of 79 points(P<0.01), and the usual results and the final results were positively correlated(r=0.865, P<0.001). The survey indicated that the students recognized the application of formative assess-ment in teaching process . Conclusion Formative assessment can help improve the teaching and learning quality in nutrition and food hygiene.
