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.

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.

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 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.

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 outcomes of applying microvascular anastomotic coupling de-vices in solitary upper extremity artery injury repairs and to optimize parameters for optimal clinical out-come.Methods:From March to September 2013,19 injured arteries from 18 male patients who presen-ted at Department of Hand Surgery,Beijing Jishuitan Hospital with traumatic arterial lacerations of their upper extremities went through rapid repair procedures.COUPLER,a microvascular anastomotic coupling device was applied in these artery injury repair operations.The 19 repaired arteries included 3 brachial arteries,6 ulnar arteries and 10 radial arteries.After the procedures,all the 18 patients were then fol-lowed up by clinical specialists and examined with color doppler flow imaging for the effective recovery of artery circulation and upper extremities functionality.Results:The average time of artery repairs for all the 19 damaged arteries among the 18 patients was 278 s and the average follow-up time was (71.5 ± 40.9)d with the longest follow-up time as 116 d and shortest as 14 d.No patient returned to the opera-ting room after the procedures and after being dismissed from the hospital.None of the 18 cases were re-ported to have problems with circulation and thrombosis formation in their upper extremities.Color Doppler imaging showed that the arterial anastomotic site for all the 19 repaired arteries were unobstructed with artery blood spectrum at both ends.Three patients with radial artery repairs complained about mild pressure pain at the site of vascular anastomosis;while the other 15 patients all expressed satisfactory outcomes of the surgery and recovery.These evidences indicated that the outcomes of our initial evalua-tion for the solitary upper extremity artery injury repairs by using anastomotic coupling devices were posi-tive.Conclusion:Our observations have showed that microvascular anastomotic coupling devices can be used for repairing of solitary upper extremity artery injures.The procedures are quick,effective and safe. The clinical application of this microvascular anastomotic coupling device in artery injures is promising, however,additional evidences through further clinical investigation with more cases are warranted.
