Objective　To investigate the causes of recurrent spontaneous abortion(RSA) and to know the relation between RSA and antiphospholipid thrombosis syndrome(APL-T). Methods　ELISA and PTT-LA were used to detect anticardiolipin antibody(ACA) and lupus anticoagulant(LA) in 32 patients with RSA and 20 normal controls(NC). Results　There were 17 positive of antiphospholipid antibody(APA) in RSA group. The incidence was significantly higher than that in NC group. The incidence of LA was also significantly higher than that in NC group. 8 patients were diagnosed as APL-T. Conclusion　LA may be the more important reason of RSA. It should be considered as APL-T when RSA is unexplained.

ObjectiveTo observe the clinical efficacy of warming-unblocking Yin Heel Vessel plus rehabilitation training in treating post-stroke strephenopodia, for seeking the optimal treatment protocol.MethodNinety eligible subjects withpost-stroke strephenopodia were randomized into an acupuncture group, a rehabilitation group, and a united group, to respectively receive warming-unblocking Yin Heel Vessel, rehabilitation treatment, and warming-unblocking Yin Heel Vessel plus rehabilitation training. ResultTwo treatment courses later, there was no significant difference in comparing the strephenopodia score between the acupuncture group and rehabilitation group (P>0.05); the strephenopodia score in the united group was significantly different from that in the acupuncture group and rehabilitation group (P<0.05), and the improvement in strephenopodia in the united group was superior to that in both acupuncture group and rehabilitation group.ConclusionWarming-unblocking Yin Heel Vessel plus rehabilitation can produce a content efficacy in treating post-stroke strephenopodia.

By summarizing the features of medical diagnosis and treatment of schizophrenia,this article mainly analyzes the ethical disfigurement and relevant harm,discusses the ethical principles and requirement which doctors and nurses should abide by during the whole medical course,so that doctors' ethical diathesis can be improved,and a harmonious physician-patient relationship can be achieved.

Co-citations of highly cited papers on gene annotation covered in Web of Science were analyzed by clustering analysis using clustering software after the word matrix of resource literature and highly cited papers was formed, which showed that the application of text mining on gene annotation includes use of authorized tools, development of text mining tools and algorithms, and verification of text mining tools.

Objective To know about care experience and medical care demands of caregivers of retinopathy of prematurity children in order to provide reference for clinic. Methods A total of 11 caregivers were interviewed by qualitative research methodology. Data and subjects were refined by Colaizzi methodology. Results Totally 3 subjects about care experience were extracted, which were high psychological pressure, heavy caregiver burden, desire for medical and nursing support. Conclusions Medical care personnel should improve treatment system of retinopathy of prematurity and provide information and psychological support in order to improve quality of life of children.

Objective To investigate the effects of heme oxygenase-1 (HO-1) on the signal transduction pathway of cigarette smoke-induced mucin (MUC) expression in airway mucous hypersecretion. Methods The cell model of mucous hypersecretion was made by human lung A549 cell stimulated by cigarette smoke extract (CSE),and treated with hemin or ZnPPIX,an inductor or inhibitor of HO-1. The expression of HO-1,dual oxidase 1(Duox1),MUC5AC,epidermal growth factor receptor (EGFR) and p-EGFR were detected. The cell viability treated with hemin or ZnPPIX was assessed by methyl thiazolyl tetrazolium method (MTT). The cells were divided into 4 groups:a negative control group,a CSE treatment group,an hemin pre-treatment group and a ZnPPIX pre-treatment group. The changes of EGFR mRNA,Duox1 mRNA,HO-1 mRNA and MUC5AC mRNA were examined by reverse transcriptase-polymerase chain reaction (RT-PCR). The protein expression changes of Duox1,HO-1,p-EGFR and EGFR were measured by Western blot,while the protein of MUC5AC in supernate and endochylema were detected by enzyme-linked immunosorbent assay (ELISA). Results The expression levels of MUC5AC mRNA and its protein in supernate liquid and endochylema in the CSE group were (0.660?0.044),(62.80?6.85) ?g/mg and (157.00?3.26) ?g/mg,and those of EGFR were 0.596?0.061 and 0.620?0.051,both of them increased significantly (P0.05),while the protein of p-EGFR,the mRNA and protein of EGFR,Duox1 and MUC5AC increased significantly (P

[Objective]To explore the effects of joint synovial fluid on tendon-bone healing of reconstructed ligament. [Methods]Forty female New Zealand rabbits,aged 6 months,weight 2.5~3.5 kg,were divided into 4 groups randomly.Transfer of semitendinosus tendon to the bone tunnels was performed to make bone-tendon healing model,on the right knee the bone tunnel was not communicated to the joint cavity,in contrast,the bone tunnel on the left knee was connected with synovial fluid.Animals in one group were killed at 8 weeks after operation,bone-tendon healing samples were harvested for biomechanical test.Animals in other three groups were killed at 2,4 and 8 weeks after operation respectively to harvest the samples for histological observation.HE and Masson staining were conducted to examinant histological change.[Results]At 2 weeks after operation,there was no significant difference between non joint synovial fluid group and joint synovial fluid group in bone-tendon interface healing,which were filled with granulation tissue.At 4 weeks postoperatively,interface healing in non joint synovial fluid group was obvious better than that in joint synovial fluid group.Fibroblast cells and cartilage cells increased obviously,and collagen fibers synthesized.At 8 weeks after operation,tendon-bone interface in joint synovial fluid group was filled with connective tissue,the collagen fibers arranged disorderly.In contrast,more compact collagen fibers were seen in non joint synovial fluid group.Interface cell accounts in non joint synovial fluid group were superior to that in joint synovial fluid group at 2,4,8 weeks after operation (P
