Objective To investigate the infection of Xuebijing injection on inflammatory factor of large sized avulsion patients.Methods 70 patients being selected with large sized avulsion were randomly recruited into a treatment group(35 patients)and a control group(35 patients).The control group received traditional comprehensive treatment.On this basis,Xucbijing injection was injected to the treatment group on admission day,and Xuebijing injection 50 ml in 0.9%NaCl solution 100 ml was,intravenously infused for 60 min once,2 times daily,up to 7 d.TNF-α,IL-6,CRP,WBC and NEU%of the two groups were respectively detected before treatment and 7 days after the treatment.Exudation of wound surface was also observed.Results After 7 days of treatment,there was significant difierence in the treatment group compared with pretreatment(P＜0.01).There was statistical difference between two groups after 7 days of treatment(P＜0.01).Exudation of wound surface of the treatment group was less than the control group's.Conclusion Xuebijing injection has antagonistic effect on inflammatory factor of large sized avulsion patients and can lessen exudation of wound surface.

Objective To observe the effect of yang-supplementing moxibustion in improving the muscular spasm, motor function, and activities of daily living (ADL) of patients with post-stroke hemiplegia.Method Totally 120 patients with post-stroke limb spasm due to qi deficiency and blood stagnation were randomized into group A, B, and C, 40 cases in each group. Group C was intervened by conventional treatment, group A was by yang-supplementing moxibustion in addition to the conventional treatment, and group B was by fire therapy in addition to the conventional treatment. The modified Ashworth Scale (MAS), Fugl-Meyer Scale (FMS), and Barthel Index (BI) were observed before and after intervention.Result Respectively after 1-month and 2-month treatment, the MAS, FMS, and BI scores were significantly different from that before intervention in the 3 groups (P<0.01). After 1-month and 2-month treatment, the MAS, FMS, and BI scores in group A were significantly different from that in group B and group C (P<0.05), and the scores in group B were significantly different from that in group C (P<0.05).Conclusion Yang-supplementing moxibustion can effectively improve the post-stroke limb spasm, and can promote the recovery of motor function.

Objective　To establish animal model for hypertrophic scar and study the characters of its morphology and collagen metabolism. Methods　A total of 64 round wounds (diameter of 6 mm each) with total skin loss were made on the ventral side of rabbit ear using a trephine. Morphology and collagen metabolism of scar wounds were studied at 14,21,35,70 and 98 days after operation, respectively. Results　There were 76% elevated scars developed (45/59 wounds) on the ventral side of rabbit ear at 21 days and 46% elevated scars disappeared (11/24) at 98 days after operation. There were numerous fibroblast proliferation and whorl-arranged collagen fibers at 21 and 35 days. The number of fibroblast decreased, but irregular-arranged fibers still presented in the elevated scars at 70 and 98 days after operation. Hydroxyproline content in elevated scars at 21 days was higher than that in normal skin (P<0.05), and at 35 days was 3 times as that in normal skin and at 98 days was also markedly higher than that in normal skin (P<0.05). Conclusion　Excessive deposition of collagen is a characteristic of hypertrophic scar in rabbits. The conversion of normal scarring to hypertrophic scarring in rabbits occurs at 14～21 days after operation. Both development and regression of hypertrophic scar in rabbit are quicker than that in human.

OBJECTIVEThere are many factors affecting the sensory integration training (SIT) effects in children with autism. This study explored the influential factors for SIT effects in the aspect of the model of sensory processing.

METHODSNinety-three autistic children aged 1.8-8.3 years were evaluated by the autism behavior checklist (ABC) and the Dunn's model of sensory processing. The SIT effects were evaluated by the sensory integrative schedule. The effects of sex, age, ABC scores and the Dunn's model of sensory processing were investigated by logistic regression analysis.

RESULTSLogistic regression analysis showed that ABC scores (Wald=6.768, <0.01) and the Dunn's model of sensory processing (Wald=13.549, <0.01) were influential factors for the SIT effects. The Dunn's model of sensory processing was shown as a more important influential factor. Sex (Wald=1.549, >0.05) and age (Wald=0.010, >0.05) were not related to the STT effects.

CONCLUSIONSThe Dunn's model of sensory processing is a major influential factor for the SIT effects in children with autism.

BACKGROUND: Elimination of antigenic substances from natural extracellular matrix with the integrity of the tissue structure retained renders the matrix to possess better biocompatibility and provides a cell culture environment close to conditions of the internal environment. Such materials are the primary choice for cell culture scaffold in tissue engineering.OBJECTIVE: To prepare human articular cartilage acellular matrix so as to provide a methodological basis for further study of articular cartilage acellular matrix as cell scaffold materials.DESIGN: A single sample study of bone tissues.SETTING: The experiment was performed in Institute of Orthopedics, General Hospital of PLA, between January and May in 2004. The specimens were obtained from patients requiring joint replacement for femoral neck fracture.MATERIAIS: The experiment was conducted in the Department of Orthopedics, General Hospital of PLA from January to May in 2004. Human articular cartilage specimens were obtained from the femoral head of patients with total hip arthroplasty for femoral neck fracture.METHODS: Totally 10 specimens of fresh articular cartilage(3.5 mm × 4. 5 mm × 2.0 mm) were obtained and freeze-dried for 12 hours. Cartilage acellular matrix was prepared using Triton X-100, Dnase and Rnase and identified by means of hematoxylin-eosin(HE) and safranine O staining and immunohistochemical staining for cartilage proteoglycan.MAIN OUTCOME MEASURES: Histological observation of the articular cartilage acellular matrix and immunohistochemical staining of cartilage proteoglycan.RESULTS: HE and safranine O staining both showed no cellular structure in the matrix with only recesses left by the removed cells. Immunohistochemical staining for cartilage proteoglycan yielded positive results, suggesting the presence of cartilage proteoglycan in the acellular matrix.CONCLUSION: Human articular cartilage acellular matrix can be prepared using the modified four-step procedures with detergent and enzymatic extraction with lyophilization, and the preserved cartilage proteoglycan in the material may retain good pressure resistance.

Objective To develop a convenient reverse transcription PCR(RT-PCR)method for identifying genotypes of human metapneumovirus(hMPV)from clinical samples.Methods According to the gene sequences of hMPV G with different genotypes,the A and B genotype specific primers were designed.A diplex RT-PCR was applied to identify different genotypes according to the molecular weight of PCR products in agarose gel.37 clinical samples were detected through this method.Results It was convenient to distinguish different genotypes of hMPV(383 bp for A and 284 bp for B)by the diplex RTPCR,and there was no non-specific amplification for common respiratory viruses.so it meant that the specificity of primers was good.The results of genotyping 37 clinical samples showed that 20 samples were identified as genotype A by both sequence analysis of M gene and diplex RT-PCR,whereas 17 samples were identified as genotype B by sequence analysis of M gene.but in these 17 samples 14 samples were identified as genotype B by the diplex RT-PCR and remaining 3 samples could not be genotyped because there was no PCR product after amplification.The consistency rate for these two methods Was 91.9%[(20+14)/37].Conclusion The method of diplex RT-PCR Was developed successfully and can be used for identify genotypes of hMPV.
