X-ray measurement is one of the most important methods for diagnosing hallux valgus. To choose the right photographed way and the proper X-ray observation index has important significance on accurate diagnosis and correct treatment. As the in-depth research on the pathogenesis and pathological changes of hallux valgus,more new X-ray measuring methods and index have appeared. X-ray in the weight-bearing and non-weight-bearing position, dorsoplantar radiograph, lateral radio-graph, oblique radiograph and sesamoid radiograph can be taken. Many observation index can be chosen,including angles, distances,the position of sesamoid et al,can be used to evaluate deformity degree before surgery and curative effect after surgery. The following is a summary of the international and domestic recent researches about X-ray observation index of hallux valgus and their applications.

OBJECTIVETo explore the clinical effects of diaplastic external fixator on the treatment of unstable fractures of distal radius.

METHODSA clinical data of 60 patients with unstable fractures of distal radius admitted to Wangjing Hospital from August 2005 to September 2009 were retrospectively analyzed with the paired design. According to the paired design, 60 patients were equally divided into two groups (internal fixation group and external fixation group), which were respectively treated with open reduction and steel plate internal fixation (internal fixation group) or closed reduction and external fixation (external fixation group), including 8 males and 52 females, with an average age of 60.27 years ranging from 34 to 85 years. Left side was in 33 cases and right side was in 27 cases. All fractures were closed and caused by hand supporting when falling down. According to AO classification, type A3 was in 22 cases, type B2 was in 4 cases, type B3 was in 2 cases, type C1 was in 20 cases, type C2 was in 8 cases, type C3 was in 4 cases. Palmar flexion, dorsiflexion, radial deviation, ulnar deviation, pronation, supination, grip strength, radial angle, radial length, volar tilt were observed before and after operation.

RESULTSAll the patients were followed up from 12 to 18 months with an average of 15.4 months. The radial length was (4.85 +/- 2.75) mm,volar tilt (14.66 +/- 10.77) degrees, radial angle (7.90 +/- 4.70) degrees in the external fixation group,while those were (4.29 +/- 1.53) mm, (14.39 +/- 5.01) degrees, (6.19 +/- 3.15) degrees in the internal fixation group, but with no statistical significance (P>0.05). Function comparison of internal and external fixation group, P-value of every function is more than 0.05 or equal to 0.05, with no statistical significance except for supination and radial deviation. The functions of wrist joints were evaluated according to Batra scoring system at 1 year after operation. The average radiological scores of external fixation group was 86.27,in which 15 cases were excellent, 11 good, 1 fair,3 poor,while the average functional scores was 94.93, and all the cases were excellent. The average radiological scores of internal fixation group was 91.27, 16 cases were excellent, 12 good, 2 fair, while the average functional scores was 94.23, in which all the cases were excellent.

CONCLUSIONCompared with the open reduction and steel plate fixation, the unstable fractures of distal radius treating by diaplastic external fixator can be achieved a similar result, with no statistical significance.

OBJECTIVETo 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.

METHODSFrom 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.

RESULTSOne 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.

CONCLUSIONThe 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.

OBJECTIVETo 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.

METHODS3 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.

RESULTSThe 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.

CONCLUSIONTreating 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.

OBJECTIVETo 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.

METHODone 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.

RESULTAll 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.

CONCLUSIONTCM 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.

OBJECTIVETo describe the epidemiological characteristics and related factors of SARS in Shanxi in order to provide scientific basis for prevention and control of severe acute respiratory syndrome (SARS).

METHODSData on clinically-diagnosed SARS cases reported to Shanxi Center for Disease Control and Prevention through SARS reporting system of Shanxi province and epidemiological reports were collected from early March to 20 May, 2003. The characteristics of SARS distribution in time, place and population in Shanxi were described. The epidemiological characteristics and related influential factors were analyzed with EPI info 6.0 software.

RESULTSSince the first imported SARS case was diagnosed clinically on 7 March and till 20 May in Shanxi province, the number of cumulative clinically-diagnosed SARS cases were 445 with an attack rate of 1.34/10,000. 20 deaths occurred in that period with the mortality rate 4.49%. The number of cases increased from 28 March and formed the first peak. However, the number continued to increase until 18 April to have formed the second peak. Since then, the number of cases has gradually decreased gradually. Since 19 May, there has been no clinically-diagnosed cases being reported. SARS cases were mostly seen in urban areas of the city (83.82% of the total SARS cases) with sporadic cases found in rural areas. Students and medical staff and people from 20 - 59 years of age occupied the large part of the cases. Age specific mortality rate increased with age and the male/female ratio was 1:0.87.

CONCLUSIONIn Shanxi province, the SARS epidemic seemed to have had the following stages: importation of the first case, gradual increase of the number of cases to reach the peak and decreasing. Case identification at early stage as well as taking measures to decrease the chance of transmission were strategically crucial for controlling the spread of SARS virus in the community.
