In order to effectively and smoothly conduct an assessment of students' study in medical physics,it is necessary to design the assessment criteria for enhancing students' development in medical physics study.This paper deals with the construction of the assessment system and the design of the assessment criteria for evaluating students' study in the education of medical physics.

How to select and organize the content of course is an important component in curriculum reform. The special part for medicine in medical physics has characteristics of medical college, and is essential. The integration of this part is difficulty in curriculum reform of medical physics. In detail, the corresponding part of physics for medicine is integrated into a topic, which followed the part of classical physics. We adopted the method of special-topic teaching. Based on teaching experiences and in combination with the practical condition of the medical college, this paper selects and recombines some course content for medicine from medical physics, which is adopted by five-year medical students. Furthermore, some teaching requirement and guidance suggestion are presented.

The first part of the work consists of thiamine analysis of 5 allotments of rice samples bought from retail shops in various districts in Canton from the end of 1954 to the beginning of 1957. Usually seven grades of rice are available, and the grades differ both in variety and extraction rate.It is found that the thiamine content of rice bought at the same time, or of the same grade bought within a few months may vary considerably. Two-third of the samples contain 0.11 to 0.18 mg of thiamine per 100 g of rice but it takes the range of 0.05 to 0.27 mg per 100 g to cover all the samples. With the exception of the lowest grade, the thiamine content in general increases with the lowering of grade and decrease of price.The second part of the work studies the influence of variety and of extraction rate upon the thiamine, niacin, riboflavin and protein content of rice. Seven varieties of rice commonly used for the seven grades extracted at different rates are obtained from a local rice mill by special arrangement with the City Food Bureau. 'Results show that milling decreases the content of these 3 vitamins and of protein, the decrease for thiamine and niacin being greater than for the other two nutrients. However, not only the original content of these nutrients in husked rice may vary, but also their degree of loss in milling may differ. Of the varieties studied the lowest grade of husked rice contains the greatest amounts of all the four nutrients while the "Super Grade A" tends to lose the least during milling. As a result, the milled products of these two varieties tend to contain slightly larger quantities of these nutrients.

Objective To evaluate the CT values in diagnosis of renal tuberculosis. Methods 26 cases were collected , the CT findings of renal tuberculosis were analysed and compared with the data of operation-pathology and clinical followed up. Results Of 26 cases, 22 cases diagnosed by CT as renal tuberculosis of one side were confirmed by operation-pathology but one (pseudaneurysm). Bilateral renal tuberculosis and renal cysts were diagnosed in 2 cases respectively by CT, while these 4 cases were confirmed as tuberculosis by other auxiliary checking methods and followed-up. The multiple tuberculoses cavities appeared as a petal-shape low-density area and other untypical signs on CT. The single cavity only showed as a low-density area should be distinguished with cystonephrosis. At early renal tuberculosis, a great quantity of effusion beneath the perinephrium was the only sign on CT.Conclusion CT scan has a special value for diagnosis renal tuberculosis. Typical renal tuberculosis can be made closely combining with the clinical information.

Objective: To investigate the association between three single nucleotide polymorphisms-2562G＞A,-416C＞G and-232G＞A in Tim-3(T cell immunoglobulin domain and mucin domain protein 3)gene promoter region and child allergic asthma in Chinese Han population by using family-based association study.Methods: Genotypes of 3 SNPs(-2562G＞A,-416C＞G and-232G＞A)in 118 allergic asthma nuclear pedigrees were analyzed by restriction fragment length polymorphism.The genotype data were analyzed by using the family-based transmission disequilibrium test(TDT).Haplotypes and their frequencies were established and analyzed by TRANSMIT software.Results: ①No transmission disequilibrium was found at the-2562G＞A and-232G＞A sites from heterozygous parents onto patients in 118 trios analyzed by TDT(P＞0.05);However,at the-416 C＞G locus,the observed values of G allele from heterozygous parents to offspring were significantly higher than the expected values(P＜0.05)②The haplotype TDT analysis by TRANSMIT showed the observed and the expected value in GCA and GGA haplotype from parents to the affected offsprings had significant difference respectively(P＜0.05).The Global X~2 test results also showed that Tim-1 haplotype were associated with child allergic asthma(X~2 = 17.26, P＜0.01).Conclusion: Tim-1 gene promoter-416C＞G locus are associated with allergic asthma susceptibility in Hubei Chinese Han population and the haplotypes constructed by-416C＞G are also associated with asthma.Tim-1 genetic polymorphism may play an important role in the pathogenesis of asthma.

objective To investigate the association between two single nucleotide polymorphisma (SNP)rsl0053538 and r810515746 in Tim-3(T cell immunoglobulin domain and mucin domain protein 3) gene promoter region and child allergic asthma in Chinese Han population from Hubei province by using faro-ily-based association study．Methods Cenotypes of 2 SNPs(rs10053538 and rs10515746)within Tim-3 gene in 118 allergic flsthma nuclear pedigrees were analyzed by restriction fragment length polymorphism and DNA sequencing．Two family-based designs，transmission disequilibrium test(TDT)and haplotype-based haplotype relaive risk(HRR)were employed for the data analysis．Haplotypes and their frequencies in 118 nuclear pedigrees were established and analyzed by Transmit software．Results The HRR analysis showed no increased risks of contracting the disease owing to rs10053538 and rs10515746 polymorphisma of Tim-3 promoter in our 118 tries(X2=2．430，P>0．05；x2=1．368，P>O．05)．N0 transmission disequilibrium was found from heterozygous parents onto patients in our 118 tries analyzed by TDT(x2=2．042，P>0．05；X2=0．750，P>0．05)．The haplotype analysis also showed no biased transmission of rs10053538 and rs10515746 haplotypes from parents to the affected offsprings(P>0．05)．Condusion The two SNPs rs10053538 and rs10515746 in Tim-3 gene promoter region are not associated with susceptibility to child allergic asthma in Chinese Han population from Hubei province．

Background and purpose:Adenocarcinoma of the esophagogastric junction (AEG) has a high incidence of early recurrence and metastasis after operation. The prognosis of AEG is poor. However, few studies have investigated the recurrence of AEG. The purpose of this study was to clarify the important clinical pathological factors affecting the early recurrence ofⅠ,Ⅱ type of AEG after operation. Thus more active treatment for patients at high risk of recurrence may improve the prognosis.Methods:This study retrospectively reviewed the clinical data from 145 AEG patients who underwent R0 resection during the period from Dec. 2008 to Dec. 2012. Risk factors associated with the early recurrence were analyzed.Results:The mean time to tumor recurrence was 25.4 months after R0 resection, and the 1-year recurrence rate was 38.6%. Univariate analysis showed that the histological grade (degree of tumor differentiation), number of positive lymph nodes, TNM stage and vascular invasion were signiifcantly related with the early recurrence (P<0.05). Logistic multivariate regression analysis showed that only histological grade and vascular invasion were independently related with early tumor recurrence (P<0.05).Conclusion:Histological grade and vascular invasion are independent risk factors for predicting the early tumor recurrence after R0 resection for AEG.

In part Ⅱ, are presented the results of the physical measurements, which include standing height, body weight, shoulder width and grip strength, made on children of middle school and children's homes. Pelidisi index is calculated by using Pirquet's formula. In tables 1 to 6 are tabulated the average results of boys and girls of ages from 12 to 18 years old. Since the results of children's homes differ from those of the middle schools, they are tabulated separately. The differences in standing height and body weight of these two groups of children are shown in figures 1 and 2. The children from the Homes are considerably shorter and lighter than school children of the some age range. The boys tend also to be narrower in shoulder width.Compared with the physical measurements of the children of Shenyang in the northeast China, the Cantonese children are slightly taller and heavier at the beginning of this age range but the children of the Northeast grow at a slightly more rapid rate, so that at 18 years of age, they are about 2 cm taller, with approximately the same body weight.Hand grip measurements show that girls have only 2/3 the grip strength of boys. Values of Pelidisi are calculated for a]l the children. It is found that this index does not proper]y represent the nutritional status of the children of Canton. By all the other indices of the state of nutrition used in this survey, the school children are rated as having a higher nutritional status, than those of the children's home, while the Pelidisi ratcs them lower.Nutrition is considered to be one of the factors which causes differences in the growth and development of the various groups of children compared.
