The article reviewed the situation of warming kidney and strengthen spleen treatment for ulcerative colitis (UC) in recent 15 years from three aspects: Yang deficiency in spleen and kidney syndrome is one of the most important syndromes in UC; common prescriptions, medicine and efficacy of warming kidney and strengthening spleen treatment for treating UC; the mechanism of the treatment for UC is related to immunity enhancement, inhibition of gastrointestinal smooth muscle, promoting gastrointestinal function, antibiosis, improving plant nerve function, and release of enzymes. It also proposed the problems about warming kidney and strengthening spleen treatment for UC, and prospect for relevant problems.

Objective To characterize the foot pressure distribution during walking of the male college students with a normal left foot and toes-out right foot gait.Methods Forty-two male college students age 20 to 25 with a toes-out gait on the right side and a normal gait on the left side were recruited.The FOOTSCAN system was used to measure their foot pressure distribution while walking.Results There were significant differences between the normal and the toes-out foot with regard to the peak pressure on the third metatarsal bone [(45.05 ±13.91)N/cm2 vs (26.83 ± 10.82) N/cm2] and pressure under the arch [(4.48 ± 1.94) N/cm2 vs (2.90 ±1.57) N/cm2],as well as the time for the appearance of peak pressure under the 1st and 4th metatarsal bones.The foot regional impulse was significantly lower on the normal side than on the toes-out side for toes 2 to 5 and for metatarsal bone 2.Conclusion In contrast to the normal foot,the pressure center of the toe-out foot deflects to the inner side.This results in slanted power application instead of straight ahead,so the strength in the direction of travel is small.And it will produce torsion between the tibia and fibula,which makes the tibia appear introverted and causes excessive friction in the knee joint.This will lead to injury of the knee joint.

Objective To evaluate the effect of lipopolysaccharide (LPS) on thymocyte differentiation antigen-1 (Thy-1) mRNA expression in mouse lung fibroblasts.Methods Primary cultured mouse lung fibroblasts were seeded in 96-well plates with the density of 1 × 104/ml.After being cultured for 48 h,the cells were randomly divided into 4 groups (n =3 each):PBS control group (group C),LPS 0.01 μg/ml group (group LPS0.01),LPS 0.10 μg/ml group (group LPS0.10),and LPS 1.00 μg/ml group (group LPS1.00).PBS was added to the 96-well plates in group C.LPS with the final concentrations of 0.01,0.10 and 1.00 μg/ml were added to the 96-well plates in groups LPS0.01,LPS0.10 and LPS1.00,respectively.After being incubated for 0,6,24,48 and 72 h (T0-4),the proliferation of the cells was measured by CCK-8 assay and Thy-1 mRNA expression was detected by real-time PCR.Results Compared with group C,the proliferation of the cells was significantly increased,while Thy-1 mRNA expression was down-regulated at T3,4 in groups LPS0.01,LPS0.10 and LPS1.00 (P ＜ 0.05).The proliferation of the cells was gradually increased,while Thy-1 mRNA expression was gradually down-regulated in groups LPS0.01,LPS0.10 and LPS1.00 at T3,4 (P ＜ 0.05).Conclusion LPS results in abnormal proliferation of mouse lung fibroblasts through down-regulating Thy-1 mRNA expression,indicating that endoxemia-induced pulmonary fibrosis is related to the down-regulation of Thy-1 mRNA expression in lung fibroblasts.
