Objective To detect the relationship between XPD Lys751Gln polymorphism and the risk of adult acute leukemia (AL). Methods 100 adult AL patients and 100 controls were chose as case and Lys751Gln were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCRRFLP) analysis in peripheral blood. Results The genotype frequency of Lys/Lys, Lys/Gln, Gln/Gln were 83 %, 16 %, 1% in case group and 90 %, 10 %, 0 in control group, respectively. The difference the two groups was no signficant difference (x2=1.44, P =0.49). No significantly increased risk for adult AL was observed for those carrying variant genotype with OR analysis (x2 = 2.10, P =0.15, OR =1.84; 95 % CI 0.80-4.25). Individuals with the variant genotype of XPD Lys751Gln might enhance the risk of adult AL (OR =2.77, 95 % CI 0.99-7.73). Conclusion XPD Lys751Gln polymorphism is found to have relationship with adult acute lymphocytic leukemia.

Objective To investigate bone strength in adults,and explore its influencing factors. Methods One hundred and ninety-one adults undergoing health examinations were selected.The questionnaires about milk intake and exercise conditions were performed,the body weight,fat mass,body mass index(BMI)and calcaneal bone strength were measured,and the relationship between each parameter and bone strength was analysed. Results Bone suength decreased with age increase,and was higher in males than that in females.Bone strength of overweight to obese adults was higher than that with normal body weight(P<0.05).Bone strength of adults with high milk intake was higher than that of those with low milk intake(P<0.05).Multivariate analysis revealed that age was negatively related to bone strength,females were more susceptible to bone strength decrease,and BMI and milk intake were positively related to bone strength. Conclusion Gender,age,BMI and milk intake are main influencing factors for bone strength.Bone strength decreases with age increase,and increase of BMI and milk intake will benefit bone strength,especially for females.

Objective To investigate the effect of pulsed ultrasound therapy (US) on medial collateral liga-ment healing in rats and it's mechanism.MethodsEighteen 3-month-old male Sprague-Dawley rats with transected medial collateral ligaments (MCLs) were studied. They were randomly divided into a control group, a 0.5 W/cm~2 group and a 1. 0 W/cm~2 group.The control group was not given any treatment.The 0. 5 W/cm~2 group and 1.0 W/cm~2 group were given 10 minutes of pulsed US (duty cycle: on/off = 3 ms/1 ms) daily for 8 days at either 0.5 or 1.0 W/cm~2 intensity. All the rats were sacrificed on the 9th day. After macroscopic examination, their MCLs were harvested and studied using haematoxylin-eosin staining, Van Gieson's staining and immunohistochemical tech-niques in order to detect transforming growth factor beta-1(TGF-β1) and any histological or histochemical changes.ResultsMacroscopically, the lacerated MCLs had healed with scar tissue formation. Scarring appeared to be greater in the 0.5 W/cm~2 and 1.0 W/cm~2 groups than in the control group. Inflamed cells appeared to be more numerous in the treated groups than in the controls. There were significant differences in collagen fiber extent among all three groups. In the 1.0 W/cm~2 group, the average level of TGF-β1 was significantly up-regulated, and TGF-β1 expres-sion was higher than in the other two groups.ConclusionsPulsed US can improve ligament healing in the short term, however whether long-term treatment with US can yield further improvement is unknown. Pulsed US can in-crease the level of TGF-β1, which will be higher with higher US dosage. Pulsed US may enhance injored ligament re-pair by up-regulating TGF-β1.Objective To investigate the effect of pulsed ultrasound therapy (US) on medial collateral liga-ment healing in rats and it's mechanism.MethodsEighteen 3-month-old male Sprague-Dawley rats with transected medial collateral ligaments (MCLs) were studied.
