Objective To investigate the diagnostic value and clinical significance of the three-dimensional contrast-enhanced MR angiography (3D-CE-MRA)in the infantile superficial hemangioma.Methods Forty-four children with superficial hemangioma un-derwent conventional and dynamic contrast-enhanced MRI.MRI scanning was started at the time of inj ection,and four dynamic pha-ses of images were acquired continually.Maximum intensity proj ection (MIP)images were reconstructed to show the blood vessels of the lesions in multiple phases.Results Forty-nine infantile superficial hemangiomas were detected by MRI,including a single le-sion in 41 patients and multiple ones in 3.3D-CE-MRA showed 37 lesions in 32 patients,and other 12 lesions were not found in 12 patients.Conclusion The conventional and dynamic contrast-enhanced MRI can reflect the location,number and the range of the su-perficial hemangioma,and show the relationship between the lesion and the surrounding tissues.3D-CE-MRA directly shows the blood supply of the tumors.

Objective To study knowledge,ability and related behavior of reproductive health among unmarried women migrants in Qingdao area,Shandong and evaluate effectiveness of basic intervention,including provision of free condom and health education and enhanced intervention,including healthy sex,contraception and health-care seeking behavior.Methods A community intervention trial was conducted among 1800 unmarried women migrants aged 18 -29 years in 10 workplaces of Qingdao.Basic intervention included health knowledge publicity and distribution of free condoms,and enhanced intervention included distribution of very important person (VIP) service cards,hotline telephone service,broadcasting digital versatile disc (DVD) of reproductive health knowledge,health lectures,peer education,and so on,in addition to health knowledge publicity and distribution of free condoms.Effectiveness was evaluated using questionnaire before and six months after intervention.Results After intervention,awareness of reproductive health and attitude to reproductive health improved significantly among the women migrants,as compared to those before intervention,particularly in knowledge of contraception and sexual health with enhanced intervention (with more than 20％ of them aware) ( P ＜ 0.01 ).About effectiveness on health-care seeking behavior,59.2％ (482/814) and 80.8％ (651/806) of the women migrants with reproductive tract infections would visit physicians after basic and enhanced intervention,as compared to those of 32.0％ (286/895) and 31.9％ (275/862) before them,respectively (P＜0.01).About effectiveness on contraceptive behavior,persistent and proper use of effective contraception methods improved significantly after intervention,as compared to that before it ( P ＜ 0.05 ),but with no significant difference between the two group with basic and enhanced intervention.Conclusions Both basic and enhanced intervention is effective and feasible in women migrants,more effective for enhanced one.

Rat brain kinesin is a conventional kinesin that uses the energy from ATP hydrolysis to walk along the microtubule progressively. Studying how the chemical energy in ATP is utilized for mechanical movement is important to understand this moving function. The monomeric motor domain, rK354, was crystallized. An ATP analog, AMPPNP, was soaked in the active site. Comparing the complex structure of rK354 x AMPPNP and that of rK354ADP, a hypothesis is proposed that Glu237 in the Switch II region sensors the presence of gamma-phosphate and transfers the signal to the microtubule binding region.

Kinesin is a motor protein that uses the energy from ATP hydrolysis to move along the microtubule system. To investigate how the chemical energy stored in ATP is converted to mechanical movement, the corresponding N-terminal region of rat brain kinesin was expressed in BL21-Codon Plus (DE3)-RP competent cells. After SP-cation exchange chromatography and size exclusion chromatography, the protein yield reached 10 mg/L culture with the purity above 95%. The purified protein had ATPase activity and specifically reacted with the kinesin antibody in the Western blotting analysis. The purified kinesin was crystallized under the following condition: 1.7 mol/L (NH4)2SO4, 500 mmol/L NaCl, 20% glycerol. The kinesin crystal can diffract up to 2.0 angstroms resolution.

Objective To investigate the expression of low molecular mass polypeptide-2 (LMP2)and protein phosphatase 1A (PPM1A) in gestational trophoblastic disease and elucidate their predictive value in malignant transformation of hydatidiform mole. Methods The expressions of LMP2 and PPM1A protein in 196 complete hydatidiform moles (in which 28 cases with malignant transformation) , 7 invasive moles, 5 choriocarcinomas and 20 normal chorionic villus were detected with the method of En Vision immunohistochemistry. Their clinicopathologic data were retrospectively analyzed. Results LMP2 and PPM1A protein expressed in cytotrophocytes, syncytiotrophoblast and extravillous trophoblast. The level of LMP2 expression in deteriorative hydatidiform mole was significantly higher than that in non-deteriorative hydatidiform mole or normal chorionic villus (6. 79 ±2. 38, 5.26 ±2.63 and 3. 10 ±1.65, all P <0. 01),while there were no difference compared with gestational trophoblastic neoplasms (6. 42 ±2. 68, P=0. 113).The level of PPM1A expression was highest in normal chorionic villus, and decreased gradually in hydatidiform mole (non-deteriorative and deteriorative) and gestational trophoblastic neoplasms (6. 30 ±2. 98, 4. 93 ± 2. 50, 4. 43 ± 2. 04 and 3. 33 ± 2. 06, all P < 0. 01); the level of PPM1A expression in deteriorative hydatidiform mole was significantly lower than that in non-deteriorative hydatidiform mole (P=0.001). The expression of LMP2 protein was correlated to theca lutein ovarian cyst, the expression of PPM1A protein was related with uterine size (P < 0. 05) . While, there was no correlation between the expressions of the two proteins (P >0. 05). Conclusions High expression of LMP2 and low expression of PPM1A might play an important role in the motility and invasiveness of trophohlast cells and malignant transformation of hydatidiform mole. Testing the expression of LMP2 and PPM1A in hydatidiform mole tissues of initial uterine evacuation might be have some reference significance in judging outcomes of hydatidiform mole.

OBJECTIVETo explore guiding role of three-column theory in manipulative reduction, small splint fixation and early rehabilitative exercises of Colles fracture.

METHODSFrom August 2011 to February 2012,47 patients with Colles fractures were treated by manipulative reduction small splinting fixation and early rehabilitative exercises under the guidance of three-column theory, including 21 males and 26 females aged from 40 to 76 years old with an average of (65.5 +/- 2.3). According to AO fracture classification, 27 patients were type A (including 18 cases with type A2 and 9 cases with type A3) and 20 patients were type C (including 10 cases with type C1, 6 cases with type C2 and 4 cases with type C3). Pain and recovery time of swelling, postoperative complications were observed and recorded, Gartland-Werley scoring system were applied for evaluate functional recovery and biomechanical analysis of wrist joint at 12 weeks after operation.

RESULTSAll patients were followed up for 3 to 9 months with average of 5 months. Pain relief time ranged from 5 to 15 d with average of (7.6 +/- 2.2) d,recovery time of swelling of opisthenar was for 6 to 13 d with an average of (8.9 +/- 1.9) d. Two patients occurred tension vesicle within 3 days after operation, but no other complications occurred. According to Gartland-Werley scoring system, 25 cases got excellent results, 18 cases good and 4 cases moderate at 12 weeks after operation.

CONCLUSIONUnder the guidance of three-column theory, treating Colles fracture by manipulative reduction, small splinting fixation and early rehabilitative exercises can reduce pain and swelling time, promote union of fracture, effectively rehabilitate wrist function, improve clinical efficacy, and fit for concept of biomechanics.
