<p><b>OBJECTIVE</b>To analyze the correlation between the hallux valgus angle and arch X-ray parameters change, plantar pressure by measuring the X-ray indexes and foot-pressure indexes in patients with hallux valgus, as well as to study the main cause factors for the pain under the second metatarsal head.</p><p><b>METHODS</b>A retrospective study of 254 patients(477 feet) treated in Wangjing Hospital from January 2012 to June 2013 was performed. The pain under the second metatarsal head and age distribution were recorded. All the patients were divided into two groups according to the second plantar bone pain: pain group and no pain group. The following indexes were measured and compared: HAVA(hallux abductor valgus angle), IMA1-2(the inter-metatarsal angle between the first and second metatarsals), IMA1-5(the inter-metatarsal angle between the first and fifth metatarsals), TAOTMLA (top angle of the medial longitudinal arch), AAOTMLA (anterior angle of the medial longitudinal arch), SMRL (the second metatarsal relative length than the first), and the plantar pressure indicators including TPUM (touch the ground time percentage under the second metatarsal head), PPUM (peak pressure under the second metatarsal head), and IUM(impulse under the second metatarsal head). All the factors were evaluated by Logistic regression analysis.</p><p><b>RESULTS</b>Spearman rank correlation test showed that there were statistical significance in correlation between HAVA and IMA1-2, IMA1-5, TAOTMLA, AAOTMLA, TPUM(<0.05, r=0.647, 0.553, 0.127, -0.165, 0.158). Factors including the HAVA, SMRL and the TPUM were the risks for the pain under the second metatarsal head in patients with hallux valgus(<0.05, ORj=1.030, 1.069, 1.060).</p><p><b>CONCLUSIONS</b>Increase of the hallux valgus angle causes the collapse of hallux valgus arch, extending the weight bearing time of the second metatarsal and increasing the possibility of the pain under the second metatarsal.</p>

<p><b>OBJECTIVE</b>To study changes in the radiographic appearance during weight-bearing and non-weigh-bearing in hallux valgus, and to analyse the correlation between the elasticity of plantar soft tissue of hallux valgus and the pain under the metatarsal head.</p><p><b>METHODS</b>From May 2012 to October 2012, 240 feet of 120 patients with hallux valgus were enrolled in the study. The degrees of the pian under the metatarsal head of all the patients were observed. AP and lateral X-ray films of feet were taken on the condition of weight-bearing and non-weight-bearing. So the hallux valgus angle (HVA), the inter-metatarsal angle between the first and second metatarsals (IM1-2), the inter-metatarsal angle between the first and fifth metatarsals (IM1-5), top angle of the medial longitudinal arch (TAOTMLA),and anterior angle of the medial longitudinal arch (AAOTMLA) were measured on the X-ray films. The differences of HVA, IM1-2, IM1-5, TAOTMLA and AAOTMLA between two groups were compared, and the correlation between the changes of IM1-2, IM 1-5, TAOTMLA, AAOTMLA and the degree of the pain under the metatarsal head were analysed.</p><p><b>RESULTS</b>One hundred and forty-eight feet had the pain under the metatarsal head. The IM1-2, IM1-5 and TAOTMLA increased on weight-bearing position compared with those on non-weight-bearing position, but the HVA and AAOTMLA decreased on weight-bearing position compared with those on non-weight-bearing position. There was a moderate relationship between the changes of IM 1-2,IM1-5 and the degree of the hallux valgus deformity, as well as the relationship between the different of IM1-5 and the degree of the pian under the metatarsal head.</p><p><b>CONCLUSION</b>The degree of the collapse of the arch of foot with hallux valgus becomes serious with its deformity increasing. The pain under the metatarsal head of hallux valgus increases with the increased changes of IM 1-2,IM 1-5 and TAOTMLA. Analysis of the X-ray observation indexes of hallux valgus on weight-bearing position and non-weight-bearing position has important significance in evaluating the degree of the collapse of the arch of foot with hallux valgus,preventing and curing the the pain under the metatarsal head.</p>

<p><b>OBJECTIVE</b>To observe the effects of the three-period treatment theory of bone fracture in TCM (Traditional Chinese Medicine) on VEGF and VEGF mRNA expression in the issues of outer periosteum, endosteum and bone marrow of rabbits, and to explore the rationality of phasing method in TCM in treating fracture.</p><p><b>METHODS</b>3 mm bone defection were made at lower one third part of both radius in 140 male healthy rabbits. The rabbits were randomly divided into four groups, including three-period treatment group (TTG), one-period treatment group(OTG), positive medicine treatment group(PTG) and model control group (MCG). The rabbits in TG were treated with three-period treatment, rabbits in OTG were treated with one-period treatment, rabbits in PTG were fed by Guzhe-Cuoshangsan (a Chinese patent medicine which was used to treat bone fracture), rabbits in model control group were given no prescription or drug but distilled water as same dose as that of other groups. At day 3, 6, 9, 14, 28, 42 and 56, five rabbits from every group were randomly selected and were killed by aeroembolism. The left radiuses were taken out as the research object. Immunohistochemistry stain and in situ hybridization stain were performed to examinate the VEGF and VEGF mRNA expression in the outer periosteum, endosteum and bone marrow.</p><p><b>RESULTS</b>The VEGF and VEGF mRNA expression of all TCM treatment groups were enhanced in the outer periosteum, endosteum and bone marrow at different time points in fracture healing. The VEGF and VEGF mRNA expression in the three tissues of TTG had the tendency of higher than that of the other groups at the most time points after operation.</p><p><b>CONCLUSION</b>Treating fracture in stages has more predominant effect on the expression of VEGF and VEGF mRNA in the outer periosteum, endosteum and bone marrow than that of treating fracture with single prescription or drug.</p>

<p><b>OBJECTIVE</b>To observe the effects of the three-period treatment theory of bone fracture in traditional Chinese medicine (TCM) on VEGF and VEGF mRNA expression in the issues of callus of rabbits. And to explore the rationality of phasing method in TCM in treating fracture.</p><p><b>METHOD</b>one hundred and forty male and healthy rabbits were made 3 mm wide bone defection at lower one third part of both radius as fracture healing model. Then those rabbits were divided into four groups randomly, which are three-period treatment group (TTG), one-period treatment group (OTG), positive medicine treatment group (PTG) and model control group (MCG). Those rabbits in TTG were treated with three-period treatment. Those in OTG were treated with one-period treatment. Those in PTG were feed by guzhecuoshangsan, a Chinese patent medicine which is used to treat bone fracture. Those in model control group were given no prescription or drug but distilled water as same dose as that of other groups. At day 3, 6, 9, 14, 28, 42 and 56, five rabbits were selected from every group randomly and were killed by aeroembolism respectively. Their radius were taken out and the left one was taken as the research object. Immunohistochemistry stain and in situ hybridization stain were performed to examinate the VEGF and VEGF mRNA expression in the haematoma, fibrous callus and soft callus.</p><p><b>RESULT</b>All TCM treatment groups can enhance the VEGF and VEGF mRNA expression in the haematoma, fibrous callus and soft callus at different time points in fracture healing. The VEGF and VEGF mRNA expression in the three issues of TTG had the tendency of higher than that of the other groups at the most time points after operation.</p><p><b>CONCLUSION</b>TCM can promote the VEGF and VEGF mRNA expression in the haematoma, fibrous callus and soft callus. Different Chinese medicines play various roles on VEGF and VEGF mRNA expression at different stage of fracture healing. Treating fracture in three-period treatment has more predominant effect on the expression of VEGF and VEGF mRNA in the haematoma, fibrous callus and soft callus than that of treating fracture with single prescription or drug. It is necessary to treat fracture in stages.</p>
