Objective To evaluate the efficacy of 90Sr-90Y applicator treatment for hemangioma by superficial ultrasound.Methods A total of 94 infants with hemangioma were retrospectively analyzed,including 37 males and 57 females (age range:1-12 months,mean =4.5 months).Thickness of hemangioma was measured by superficial ultrasound on the day before 90Sr-90Y applicator treatment,10 d and 3 months after treatment.Paired t test and x2 test were used to analyze data.ROC curve was analyzed to determine the tumor thickness which could be cured by one-cycle of treatment.Results Sixty-two cases were cured,29 cases had partial response and 3 cases had treatment failure.Thickness of hemangioma was (0.38 ±0.28)cm before treatment and (0.16±0.35) cm 3 months post-treatment and the difference was statistically significant (t=7.377,P＜0.05).The treatment effect of 90Sr-90Y applicator was not influenced by gender.According to the site of hemangioma,the curative rates were 20/38 in head & neck,22/33 in chest,20/23 in limbs.Only the difference between the curative rates in head & neck and limbs was statistically significant (x2 =7.478,P＜0.05).The treatment effect of 90Sr-90Y applicator was evaluated by the thickness of hemangioma under the skin at 3 months post-treatment and the area under the ROC was 0.93.The threshold of the thickness of hemangioma which could be cured by one-cycle of treatment was 0.32 cm with the sensitivity of 93.8％ and specificity of 85.5％.Conclusions The 90Sr-90Y applicator had a good treatment effect on pure hemangioma in infants,especially for those located in limbs and torso.The lesion with thickness less than 0.32 cm had a higher chance to be cured by one-cycle of treatment.

[Objective]To study the relationship between the existence and types of mediopatellar plica versus the chondral injury of the medial femoral condyle.[Method]Data were collected retrospectively from the photographic recording of arthroscopies performed from January 2004 to July 2008.Seventy-six knees were found with mediopatellar plica as the study group.Modified Sakakibara classification and the chondral injury(using the Outerbridge classification) of medial femoral condyle were recorded.Eighty knees without mediopatellar plica were randomly collected as controls.The correlation of mediopatellar plica and the cartilage injury on the surface of the medial femoral condyle was investigated.[Result]Patients with mediopatellar plica had a significantly higher incidence rate(89.5%) of medial femoral condyle cartilage lesion,in comparison with patients without mediopatellar plica(61.3%)(P=0.001).In the study group,a 64.3% proportion of the group with Sakakibara A mediopatellar plica was found to have cartilage lesion in the medial femoral condyle.The proportion of the group with Sakakibara BCD mediopatellar plica was found to be 95.2%,significantly higher than that in first group(P=0.004).The severity of cartilage injury in the medial femoral condyle was positively correlated with patient age(r=0.271,P=0.019) and the severity of the pathologic change of the mediopatellar plica(r=0.611,P=0.000).[Conclusion]According to this observation,the cartilage injury in the medial femoral condyle is more commonly found in patients with mediopatellar plica knees.A shelf-like appearance of the medial plica can increase the incidence of the cartilage injury.The severity of cartilage injury was positively correlated with patient age and the severity of the pathologic change of the mediopatellar plica.

Objective To explore the construct validity of collectivism and individualism scale( COLINDEX) and the reliability and construct validity of its Chinese revision;and to study the development of middle school students' value. Methods The revised scale was used and 5875 middle school students were tested. Resuits Two-factor model of COLENDEX was not substantiated by data,while three factors were abstracted by EFA and confirmed subsequently by CFA. Four factors were abstracted from the Chinese revision of COLINDEX, and four-factor model was confirmed. The Cronbach's alpha coefficients of the total scale (0.90) and four sub-scales (0.84,0.76,0.84 and 0.74 )were all significantly high. MANOVA was performed to detect gender and grade differences of means in the four dimensions of the revised scale. The main effects of gender and grade reached the significant level; however, interaction between them did not. Conclusion Collectivism and individualism, two dimensions of Chinese middle school students' value, were not mutually independent. The revised version of COLINDEX was qualified to be used in further research. The grades on collectivistic items of middle school students were higher than those on individualistic items.

CD133 has been confirmed as a stem cell surface marker in a variety of tumors.Specific markers of cancer stem cells in the thyroid cancer are not yet clear.Results of some studies showed that expression of CD133 was found in undifferentiated thyroid cancer cells which had the characteristics of stem cells.Those cells had the ability to self-renewal,multi-directional differentiation,potential development to cancer,and radio-and chemotherapy resistance.This article mainly views the progresses of CD133 in thyroid cancer research.

Objective To study the plasma antioxidant vitamin status in patients receiving enteral nutrition(EN) or parenteral nutrition(PN) after upper gastrointestinal surgery.Methods One hundred and twenty patients who underwent upper gastrointestinal cancer surgery were randomized into EN and PN group.The plasma vitamin A,vitamin E and ?-carotene levels pre-and post-operation and one week after clinical nutrition supplement were studied.Results Vitamin A and ?-carotene levels decreased significantly after surgery(P=0.03 and P=0.01,respectively).Vitamin E decreased 10 weeks after the nutrition,and it was significantly lower in the EN group than in the PN group(P0.05).Conclusions A decrease of antioxidant vitamins is induced by surgery and vitamin E is recommended to be given in nutrition supplement patients,especially in the patients receiving EN.

Objective To evaluate the effect of YunKe on bone metabolism of patients with rheumatoid arthritis (RA). Methods A total of 108 RA patients were divided into YunKe group (n = 72), non-YunKe group (n = 36), and 54 controls. The bone mineral densities (BMDs) of the wrists, hips and lumbar spines were measured by dual-energy X-ray absorptiometry. Moreover , the expression of cross-linked N-telopeptides of type I collagen (NTX) in the serum was detected for statistically analyzing the difference between YunKe group and non-YunKe group. Results In RA group, the BMDs of wrist, hip and lumbar spine declined compared with that of control group (P < 0.001, respectively). In YunKe group, the BMDs of wrist, hip and lumbar spine after 6 months all were improved with statistically significance (P < 0.01, respectively); The differences also were statistically significant when compared with those in non-YunKe group (P < 0.01, respectively). In YunKe group, NTX level in the serum declined after 3 months of the treatment. The difference was statistically significant when compared with that in non-YunKe group (P < 0.001), but the difference disappeared 6 months later. Conclusions The BMD of wrist joints is low and declines in RA patients significantly. The treatment withYunKe improves the BMDs of the wrist , hip and lumbar spine and decreases the serum NTX. This study proposed that YunKe could inhibit the chronic loss of bone mass induced by RA.
