OBJECTIVE:To observe the clinical therapeutic effect of KLT combined with chemotherapy on late can?cers.METHODS:64patients with late cancers were assigned as observation group:receiving KLT+chemotherapy;47patients with late cancers were assigned as control group:receiving routine chemotherapy.RESULTS:In the observation group,the ef?fective rate was48.44%,body weight increase accounted for57.81%,KSP increased85.93%and relief from pain accounted for71.87%;In the control group:the effective rate was34.04%,body weight increase accounted for22.66%,KSD increased48.93%and relief from pain accounted for46.81%.The incidence of ARDs in observation group was obviouly lower than those in control group.CONCLUSION:KLT combined with chemotherapy can raise the therapeut effect on patients with late cancers and improve their life quality.

Gait recognition is a new technology in biometric recognition and medical treatment which has advantages such as long-distance and non-invasiveness. Depending on the differences between different people's walking pos tures, we can recognize individuals by characteristics extracted from the images of walking movement. A complete gait recognition process usually includes gait sequence acquisition, gait detection, feature extracting and recognition. In this paper, the commonly used methods of these four processes are introduced, and feature extraction methods are classified from different multi-angle views. And then the new algorithm of multi-view emerged in recent years is highlighted. In addition, this paper summarizes the existing difficulties of gait recognition, and looks into the future development trends of it.

CK.Efficiency of Myo decreases apparently after heart accident onset is more than 6 hours.Traditional marker,CK,CK-MB,AST,LDH and HBDH still have some efficiency in AMI diagnosis.

Objective: TO study the change of substance P(SP) level in Plasma and its relationship with ankylosing spondylitis(AS).Method: Radioimmunoassay. Results: The author observed that the level of SP in Plasma of AS is singificantly higher than that of healthy controls. SP level in AS patients during active stage is higher than in those during inactive stage. Conclusion: Increased SP may play an importantrole in the pathogenesis Of AS.

Objective To evaluate the role of lumbosacral somatosensory evoked potential (LSSEP) examination in the diagnosis of lumbosacral disc herniation (LDH). Methods Somatosensory evoked potential (SEP) from posterior tibial nerve, L_4, L_5 and S_1 dermatomes SEP, and lumbosacral SEP was recorded in 54 patients with radiculopathy caused by LDH. Results The SEP from posterior tibial nerve was abnormal in 22 cases (40.74%). The SEP from L_5 and/or S_1 dermatome was abnormal in 47 cases (87.04%, P

膀胱癌是泌尿系统器官中最常见的恶性肿瘤之一，其病因及发病机制尚不十分清楚，且其具有发病率高、恶性程度高 以及术后易复发等特点，因此对其病因、发生发展的具体分子机制的研究及阐明，将有力地促进膀胱癌的诊断及治疗。长链非编 码RNA（long non-coding RNA，lncRNA）是细胞中一类转录本长度超过200个核苷酸的非编码RNA分子， 占RNA总量的98%。 lncRNA具有与mRNA相似的结构，经过转录后加工，也具有polyA尾巴和启动子结构，但是由于序列中缺少开放阅读框，而不参 与或很少参与蛋白质编码。近年来，随着二代测序技术的广泛应用，越来越多的研究发现lncRNA在多个层面上参与细胞分化和 个体发育等重要生命活动过程的调控，并与人类的重大疾病尤其是肿瘤密切相关。相关的研究表明，lncRNA参与靶基因的表达 调控，在肿瘤的发生发展中发挥着重要的作用。本文对lncRNA在膀胱癌方面的最新研究进展进行了文献综述。

Objective To explore an easier method to get epithelial cell and fibroblast from a rabbit' s trachea for trachea tissue engineering in vitro. Methods Digest the epithelial cell and fibroblast by trypsin after co-culture for 6 days. Distinguish these two kinds of cells according to their different tolerances to trypsin and culture characteristics. The new method and the traditional method were compared by the proliferation of the cells with cell counting and MIT assay. Results The purity of the cells got with this new method is up to 100% . The cells proliferation is as same as that cultured by traditional methods. Conclusion With this method, one can get two kinds of different cells from the original in one time, it is easier to practice than the traditional.

Objective To induce regeneration of dog's tracheal cartilage by implanting the recombinant human bone morphogenetic protein-2 (rhBMP-2) into the tracheal graft in order to prevent the trachea from collapse. Methods RhBMP-2 with the atelopeptide type-1 collagen carrier was implanted around the cartilage ring of the autograft. New cartilage formed was detected with the histological analysis and immunohistochemical stain after 4 weeks. Six different concentrations of rhBMP-2 with collagen carrier were implanted around the cartilage ring in 6 auto transplantation groups respectively. The area of new cartilage regeneration was calculated in choosing the optimal dosage of rhBMP-2. Auto and allo tracheal transplantation were performed with rhBMP-2 implanted around the cartilage ring, the diameter of the grafts, histological analysis, and the area of the new cartilage regeneration were calculated. Results The addition of rhBMP-2 resulted in significantly greater amount of the new cartilage area (P

Objective:To explore the therapeutic effect of the extraction of bone-melon injection for the earlier fracture.Method:100 patients with early fracture were divided into two groups.50 cases in the treatment group used the extraction of the bone-melon injection and 50 cases in the controlled group used compound ossotide injections.Their curative effects were judged according to their healing time,level of relieving pain and functional recovery condition.Result: The patients in the treatment group healed earlier(P

Objective Three soluble materials were used as carrier of recombinant human bone morphogenetic protein-2(rhBMP-2) in order to seek suitable slow-release carrier of rhBMP-2,which induced neogenetic cartilage in canine tracheal autografting segment.Methods 32 mongrel dogs were randomly and equally divided into 4 groups.A five-ring cervical tracheal segment was harvested as the autograft.The materials including dextran,polyvinyl pyrrolidone(PVP) and collagen were respectively combined with equal rhBMP-2 and then injected into the soft tissues between cartilaginous rings of autografts.In addition,without carrier group was used as controls.Then the autografts were heterotopically transplanted into greater omentum.The animals were sacrificed at postoperative 4 weeks,and the postmortem specimens were examined grossly and histologically.Results Cartilage rings of the grafts were partly absorbed in all four groups.New cartilage was induced in the rhBMP-2 injected area in the groups in which PVP or collagen was used as carrier,and more new cartilage was observed in the collagen group.Conclusions PVP and collagen could be sustained as release carriers for rhBMP-2 in tracheal autograft.Collagen is more effective as a carrier than other vehicles and it could enhance the ability of rhBMP-2 inducing cartilage regeneration in tracheal transplantation.
