Objective To compare the risk factors of mild hemorrhage and diiferences of TOAST type in patients with acute cerebral infarction (ACI) and transient ischemia attack (TIA).Methods Forty patients with mild hemorrhage were divided into ACI group(24 cases) and TIA group(16 cases) according to disease classification.Risk factors such as age,blood pressure,blood lipid and so on between 2 groups were compared,TOAST subtype differences of 2 groups were compared.Results The age [(73.3 ± 4.1) years],the ratio of hypertension [95.8％(23/24)],leukoaraiosis [70.8％(17/24)] in ACI group was significantly higher than that in TIA group [(65.5 ± 5.6) years,13/16,9/16],there was significant difference (P ＜ 0.05).The ratio of large-artery atherosclerosis and cardioembolism in ACI group [75.0％ (18/24) and 16.7％ (4/24)] was significantly higher than that in TIA group (8/16 and 1/16),there was significant difference (P ＜ 0.05).But the ratio of small artery occlusion in ACI group [8.3％ (2/24)] was significantly lower than that in TIA group (7/16),there was significant difference (P ＜ 0.05).Conclusion Correlative risk factors of milde hemorrhage in ACI and TIA patients have significant differences.

In order to set up sustainable fundraising mechanisms for community health services, it is necessary to calculate the sum of compensation needed for basic public health services and formulate compensation policies on the basis of defining items of basic public health services and in accordance with the economic levels of various regions. At the same time, it is necessary to enforce government purchases after working out strict assessment criteria so as to ensure that funds for community health services are genuinely devoted to basic public health services.

[Objective]To observe the growth status and osteogenic potential of gene transferred mesenchymal stem cells with Ad-BMP-2 planted on allogenetic acellular and decalcified bone matrix served as tissue engineering scaffold.[Method]Rabbit mesanchymal stem cells transferred with Ad-BMP-2 were seeded on allogenetic acellular and decalcified bone matrix,the growth status of gene transferred MSCs on the scaffold was observed by scanning electron microscopy and the ostengenic potential was observed by testing contents of ALP and BGP and secretion of Collagen I in the culture supermatant.[Result]The MSCs transfected with Ad-BMP-2 grew well on the tissue engineering scaffold,the osteogenic ability of the gene transfected MSCs showed great significant difference compared with that of the control group.[Conclusion]The MSCs transfected with Ad-BMP-2 can grow well on the acellular and decalcified bone matrix and the osteogenic potential can be great improved by gene transfection.

Objective To evaluate development of postoperative complications of calcanens fracture by employing Evidence-based medicine method so as to provide basis for clinical treatment strategy. Methods Eligible literatures on surgical treatment of calcalneus fractures from 1989 to 2008 were retrieved through Medline, Cochrane Database, Embase Database and Science Direct. The retrieved literatures were organized and analyzed by using SPSS14.0 and RevMan5 software. Results A total of 1823 literatures on calcaneus fractures were originally obtained based on preset retrieval conditions. With screening and evaluation, 29 clinical reports involving 2 661 patients (2 800 feet) met the criteria of meta-analysis. The results of recta-analysis indicated that the incidence rates (IR) and confidence interval (CI) of the complications that included infection (IC =8.6%, 95% CI =7.53-9.61), wound-edge necrosis (IC =2.6%, 95% CI =2.05-3.24), subtalar arthritis (IC =2.0%, 95% CI = 1.42-2.44), peroneal tendinitis (IC = 1.3% , 95% CI = 0.84-1.66), vascular or nerve damage (IC = 1.2%, 95% CI 0.81-1.62), osteotitis of calcaneus (IC = 1.0% ,95% CI 0. 60-1.33), non-union (IC =0.2%, 95% CI = 0. 04-0. 39) , malreduetion (IC = 0. 1%) and painful implants (IC = 0.7% , 95% CI = 0.4-1.03) respectively. Conclusion The postoperative complications of calcaneus fracture are common clinical problems, to which professional care without delay can attain satisfactory outcome.

Objective To construct a rat fixation device for local infra-red irradiation in rats, observe the binding effect of this fixation device, and assess its practical application.Methods Twelve SD rats were held by this home-made simple device.The holding time was recorded at room temperature (24℃ to 26℃), 38℃ to 39℃ and 42℃ to 43℃ by infrared irradiation, respectively, and the maximum observation point was 60 min.Results Most rats (10/12) were held for more than 30 minutes at room temperature, 38℃ to 39℃ and 42℃ to 43℃ infrared irradiation.While 8 rats reached 60 min.There was no statistically significant difference among the holding times at various temperatures (P > 0.05).Conclusion This self-made device is simple, easy to operate and can be used to hold rats for a long time, and is a convenient and reliable holding device in animal experiments.

[Objective] To research the plantar pressure distribution of the normal Chinese adult. [Method] The F-scan plantar pressure analysis system was used to collect plantar pressure distribution data of 100 volunteers who stand, walk, jog, go upstairs and downstairs.The plantar pressure distribution data of 5 kinds of physiological states, as well as influence of sex, height, body weight, body mass index and speed was analyzed. [Result] There's different characteristic between 5 kinds of states of the plantar pressure distribution in the Chinese normal adults. There's significant difference between static and dynamic. In four dynamic motions, the gait of walk was stalest, and it became unstable if speed up and go upstairs or downstairs. As for the influential factors of the plantar pressure distribution, there was non-significance of sex. But the speed had the significance. The height, the body weight, the BMI had weak correlation with the plantar pressure distribution. [Conclusion] The plantar pressure distribution of normal Chinese adults has the distinctive quality. The data obtained by this experiment, may provide the reference for the clinical plantar pressure analysis.

Objective To discuss the methods of the operative treatment for posterior tibial tendon dysfunction (PTTD). Methods From December 2002 to June 2005, 8 cases of PTTD were treated with operations, including 2 males and 6 females with an average age of 47 years (range, 36 to 56 years). Left side was involved in 6 cases, and right side was affected in 2 cases. Stage Ⅱposterior tibial tendon dysfunction were 2 feet and stage Ⅲ were 6 feet. Every case with special operative treatment, for instance lateral column lengthening, arthrodesis, repair posterior tibial tendon, spring ligament reefing, flexor digitorum longus tendon transfer and so on. Every bone operation was combined with one or more than one sofe tissue operation. Anterior transfer and strengthening of posterior tibial tendon were performed in 4 cases, spring ligament reefing in 2 cases, flexor digitorum longus tendon transfer in 4 cases. All patients were fixed with plaster cast at inversion position for 4-6 weeks, then changed to plaster splint fixing at neutral position for 4 weeks. Functions of ankle and foot were evaluated before and after operation. Results All patients were followed up for an average of 28 months(range, 12 to 40 months). According to Maryland foot score, 2 were fair and 6 were failure in preoperative, 4 were excellent, 3 were good and 1 was fair in postoperative. The total excellent and good rate was 87.5%. The specific index of X-ray improve obviously(P

[Objective]To discuss the operative treatment for adult flatfoot deformity with severe pain.[Method]From August 2002 to October 2004,operative treatment for 12 cases of unilateral adult flatfoot deformity with severe pain underwent operative treatment,which included 7 males and 5 females with an average age of 35 years(range,20 to 56 years),left side was involved in 8 cases,and right side was affected in 4 cases.According to etiological factor,stageⅡ~Ⅲ posterior tibial tendon dysfunction were 6 feet,congenital flatfoot were 3 feet,neurological flatfoot were 2 feet and postoperative equinovarus was 1 feet.Every case received special operative treatment,for instance lateral column lengthening,medial displacement calcaneal osteotomy,arthrodesis,repair posterior tibial tendon,sping ligament reefing,FDL tendon transfer and so on.All patients were fixed with plaster cast at inversion position for 4~6 weeks,then changed to plaster splint fixing at neutral position for 4 weeks.Functions of ankle and foot were evaluated before and after operation.[Result]All patients were followed up for an average of 22 months(ranged,16 to 28 months).The total excellent and good rate was 83.3% according to Marryland foot score.The specific index of X-ray improved obviously(P
