BAcKGROUND:The specific research on the interaction between feet and ground when jogging,plays an important role for a deeper understanding of the basic laws of human motion.OBJECTIVE:To test dynamic foot pressure distribution during jogging of 64 undergraduates.DESIGN,TIME AND SETTING:A single sample design,the experiment was carried out in Tianjin Normal University Sports Institute in March 2009.PARTICIPANTS:A total of 68 male collego students,without history of foot traumatic or deformities and with normal ankle joint,were involved in this study.METHODS:Totally 68 university students were analyzed by the Footacan USB2 system(RSscan,Belgium)when jogging atnormal gait(5m/s).Dynamic foot pressure was determined three times.Analysis of foot pressure distribution system could gain a complete gait cycle of foot pressure distribution,data acquisition and analysis software used footscan SOFTWARE7.0,foot process of analysis was divided into 10 regions:the first phalange,the second to the fifth phalanges,the first metatarsal,the second metatarsal,the third metatarsal,the fourth metatarsal,the fifth metatarsal,arch,medial heel and lateral heel.MAIN OUTCOME MEASURES:Foot pressure,intensity of pressure,force interval and impulse when jogging.RESULTS:The foot stress-time curve showed a single peak;foot maximum pressure located at the second metatarsal,the site of impulse descending order was the third metatarsal.the first metatarsal,heel,the first phalange,the fourth metatarsal,the fifth metatarsal,the second to the fifth phalange,arch;the distribution of both feet was similar.The pressure of right foot in the second metatarsal,the first metatarsal and the first phalange was significantly greater than the left foot;The contact phases of the full foot and deport from ground occupied 90% of support time,the pressure center was densely in the middle of half sole,the fore intarval of sole was long.The contact time of right foot was significantly larger than left foot.The biggest impulse was the site of the second metatarsal,the order from great to small was the first metatarsal,the third metatarsal,the first phalange,heel,the fourth metatarsal,arch.the second to the fifth phalange,the fifth metatarsal;the distribution of both feet was similar.The impulse of right foot was greater than left foot,while the impulse of the second metatarsal,the first metatarsal and the first phalange were greater than left foot,the difference had statistical significance.CONCLUSI0N:The largest pressure part is the second metatarsal when jogging,the pressure center in the foot locates in the middle of half sole,and the largest impulse is the second metatarsal,most of the impulse focus on the front end of the first to the third metatarsals of the half sole.It is indicated that the middle part of the footpad would be injured easily when jogging,so we should pay attention to the selection of shoes when exercising.

Objective To explore the relationships between Serum levels of tumor necrosis factor-alpha TNFα,1L-6,adiponectin and insulin resistance in type 2 diabetes.Methods 80 T2DM patients and 40 healthy controls were recruited.Levels of serum TNF-α,IL-6,adiponectin,plasma glucose,insulin and BMI were measured.Insulin resistance was evaluated by HOMA-IR.Results The levels of TNF-α and IL-6 in T2DM group were significantly higher than that in control group(all P＜0.05);The levels of adiponeetin in T2DM group was significantly lower than that in control group(P＜0.05).The levels of TNF-α and IL-6 were positively correlated with HOMA-IR(P＜0.05),adiponeetin was egatively correlated nwith HOMA-IR(P＜0.01).Conclusion TNF-α,IL-6 and adiponectin were closely related with insulin resistance,and should take parts in development of T2DM.

Objective To probe the relationship on TCM syndromes and related index of metabolic syndrome.Methods 1124 people who receive physical examination were undertaken TCM syndrome differentiation,and five viscera syndromes,the deficiency syndromes,excess syndromes,cold and heat syndromes were found.The relations between TCM syndromes and waist circumference,triglycerides,high-density lipoprotein,blood pressure,fasting blood glucose were studied.Results ①The deficiency syndrome groups and the groups of metabolic syndrome related index by clustering analysis had a higher consistency.②Discriminated analysis demonstrated waist circumference,high-density lipoprotein,and diastolic blood pressure could be used to determine liver syndrome.Blood sugar could be used to determine kidney syndrome.Waist could distinguish blood deficiency syndrome.Blood glucose and systolic blood pressure could distinguish Yin deficiency syndrome.Systolic blood pressure could determine Qi stagnation syndrome.Siastolic blood pressure could determine heat syndrome.The liver syndrome group and the actual liver syndrome group had higher consistency by discriminated analysis.After establishing the discriminated equation,total correct rate of distinguishing were 57.3％,67.1％,63.8％,61.5％,52.4％,47.2％.③Receiver operating characteristic curve analysis showed that blood glucose had diagnostic significance to renal syndrome.The area under the curve was 0.562.Triglycerides,blood glucose,blood pressure had diagnostic significance to Yin deficiency syndrome.The areas under the curve were 0.541,0.556,0.580 and 0.569.Waist circumference,triglycerides,high-density lipoprotein had diagnostic significance to moisture syndrome.The areas under the curve were 0.622,0.609 and 0.605.Diastolic blood pressure had diagnostic significance to heat syndrome.The area under the curve was 0.544.Conclusion By the multifarious analytical methods,we can see that syndromes have more contacts to related index of metabolic syndrome.

Objective:To observe the clinical effects of acupuncture at Yaotongdian (EX-UE 7) plus the oblique Ban-pulling manipulation for acute lumbar sprain. Methods:A total of 180 patients were divided into an observation group and a control group by drawing lots. The 98 cases in the observation group were treated by puncturing Yaotongdian (EX-UE 7) plus the oblique Ban-pulling manipulation. The 82 cases in the control group were only treated by the oblique Ban-pulling manipulation. After the two groups were treated continuously for three sessions, the therapeutic effects were observed. Results:In the observation group, 96 cases were cured and 2 cases were improved; the curative rate was 98.0% and the total effective rate was 100%. In the control group, 76 cases were cured, 4 cases were improved and 2 cases failed; the curative rate was 92.7% and the total effective rate was 97.6%. In comparison of the curative rate and total effective rate, the differences were not statistically significant (P>0.05). But, the curative rate after the first treatment was higher in the observation group than that in the control group, with a significant difference between the two groups (P<0.05). Conclusion:The therapeutic effects were similar by acupuncture at Yaotongdian (EX-UE 7) plus oblique Ban-pulling manipulation and by single oblique Ban-pulling manipulation for acute lumbar sprain. But, it took effect quickly by puncturing Yaotongdian (EX-UE 7) plus the oblique Ban-pulling manipulation.

Objective To investigate the relationship between the autoantibody detection and abortion of pregnant women.Meth-ods The dot immunogold method,indirect immunofluorescence and enzyme-linked immunosorbent assay(ELISA)were used to de-tect serum anti-double stranded DNA antibody (dsDNA),anti-smooth muscle antibody (SMA),antinuclear antibody (ANA),anti-endometrial antibody (EMAb),anti-cardiolipin antibody(ACA),anti-sperm antibody (ASAb),anti-ovarian antibody(AoAb).Re-sults Compared with healthy pregnant women,the values of EMAb,ACA,AoAb,ANA and SMA in abortion pregnant women were increased with statistical differences (P <0.05).Conclusion EMAb,ACA,AoAb,ANA and SMA have high correlation with abortion of pregnant women.Confirming the causes of unexplained abortion and prenatal screening are especially important for the pregnant women in the border area.

Recently, double-hit lymphoma (DHL) was clarified to be a molecular category of B-cell lym-phoma, which was mainly related to MYC and Bcl-2 genes translocation. Fluorescence in situ hybridization (FISH) is the gold standard of diagnosis and it is controversial to detect the expression of MYC and Bcl-2 protein by immuno-histochemistry. DHL, which was found to be aggressive according to many retrospective analyses, mainly develops in patients with diffuse large B-cell lymphoma and grey zone lymphoma. Both rituximab combination and transplant consolidation were not able to signiifcantly overcome the poor prognosis of DHL. Novel and speciifc molecular targeted agents need to be explored and investigated in order to improve the treatment outcome.
