Objective:To diagnose training injuries in the crew undergoing escort mission in Gulf of Aden with color Doppler ultrasound, and to investigate the incidence of common military training injuries and positions prone to occurrence.Methods:The occurrence of training injuries during escort mission was investigated and analyzed by reviewing the outpatient registration book and using Sonoscape S8 portable color Doppler ultrasonic diagnostic apparatus. The diagnosis of military training injuries was based on the relevant standards of Diagnostic Criteria and Prevention Principles of Military Training Injuries compiled by the CPLA Medical Research Institute of Military Training. Results:The total incidence of training injury was 13.13%, among which muscle training injury took up the largest portion, accounting for 31.21%. The training injury incidence of special operations personnel was 36.67%, ranking first among all the posts.Conclusion:Color Doppler ultrasound can provide a diagnostic basis for long oceangoing military training injury.

OBJECTIVETo investigate if there are microsatellite loci in the long arm of chromosome 6 that have close relationship with non-small cell lung cancer.

METHODSMultiple PCR approach was used to analyze the 18 loci in the long arm of chromosome 6. The PCR products were analyzed in PAGE, and then the electrophoresis maps were analyzed with Gene Scan(TM) and Genotyper(TM).

RESULTSThere were different frequencies of loss of heterozygosity (LOH) in different loci (varying from 3.85% to 38.45%). The total frequency of LOH in 41 gastric cancers was 58.5%(24/41). Eight loci with the LOH frequency higher than 20% were mainly located in 2 regions: 6q24 and 6q27. The accurate location is 6q24-6q25.3 [D6S1699(35%), D6S409(23.33%), D6S441(33.33%)] and 6q26-27 [D6S1550(38.45%), D6S264(20%), D6S1585(25%), D6S446(33.33%), D6S281(30.77%)].

CONCLUSIONThere may be tumor suppressor genes located in the region of 6q24 and 6q27, which have close relationship with non-small cell lung cancer.
