BACKGROUND: To summarize the feature and clinical application of various injectable bone substitutes.DATA SOURCES: The computer-based research was done in Pubmed database for articles concerning various injectable bone substitutes published from January 1995 to May 2009 with the key words of "injectable bone substitute, bone injury" in titles and abstracts. Literatures of the same fields published in recent years or in authorized journals were selected.DATA SELECTION: Latest literatures addressing feature and clinical application of various injectable bone substitutes were selected; old and repetitive studies were excluded. Finally, 21 articles were included.MAIN OUTCOME MEASURES: Feature and clinical application of various injectable bone substitutes were measured.RESULTS: Present various injectable bone substitutes contained complex hydroxyapatite bone substitutes, complex calcium sulfate bone substitutes, and complex calcium phosphate bone substitutes. Addition of bone morphogenetic protein-2 etc. in injectable bone substitute could significantly elevate bone union speed, promote osteoblastic proliferation, and overcome disadvantage of physical bone substitute to some degrees. Addition of platelet-rich plasma could promote repair effect of injectable bone substitute on bone defects, and promote differentiation of bone marrow stromal stem cells and proliferation of osteoblasts. Addition of cells could make up the insufficiency of physical materials to great degrees.CONCLUSION: The compound injectable bone substitute has a bright perspective of clinical application. Injectable bone substitutes combined with cells (especially stem cells) will be a new direction for biomaterial development in the future.

As a tool, cholelithiasis animal models have become an important platform for pathogenetic, preventative, diagnostic and therapeutic research. As biliary calculus formation has a close relationship with dysfunction of hepatic and biliary systems, inability of lipid metabolism homeostasis and impairment of immunologic barriers, increasing studies have been carried out with the use of animal models in these fields. Animal genetic susceptibility to cholelithiasis has greatly attracted people's attention in recent years and cholelithiasis animal models have been used in Chinese traditional medicine development and authentication. Furthermore, reports on invasive and traumatic research have been published in which large animal models were used. It is supposed that technical progress and scientists' demands would result in wide application of more kinds of cholelithiasis animal models.

Objective To observe the application effect of mental nursing on perioperative nursing of patients. Methods 66 patients with cutaneous carcinoma were randomly divided into the conventional nurs-ing group and the psychological intervention group. The conventional nursing group received perioperative mu-fine nursing,the psychological intervention group was given mental intervention before,during and after operation based on routine nursing. The anxiety value was measured before and 30 minutes after the operation, pain de-gree was assessed 30 minutes after the operation,the results underwent t test and X2 teat. Results Compared to the conventional nursing group, the anxiety value before the operation and 30 minutes pestoperation as well as pain degree 30 minutes pestoperation of the psychological intervention group were significantly decreased. Conclusions Mental nursing of patients with cutaneous carcinoma can efficiently eliminate or re-duco patients' psychologic obstacle and significantly reduce patients' painful feeling.

AIM: To explore the effect of acute and chronic hypoxia on the chemotaxis of polymorphonuclear leukocytes(PMNs) of rats.METHODS: Serum and PMNs were separated from rats under normoxia, acute hypoxia and chronic hypoxia condition,and cell aspiration technology system was used to determine the chemotactic migration of pseudopod of PMNs induced by serum as chemotactic factor.RESULTS: Induced by autoserum,the length of pseudopod of PMNs migrated into micropipette [(1.200?0.178)?m,(1.094?0.164)?m ]under acute hypoxic and chronic hypoxic condition was significantly longer than the corresponding value for control[(0.914?0.156)?m,P

BACKGROUND:Studies have shown that as a regulator of bone marrow functionerythropoietinis a glycoprotein that controls the development of the central nervous system and has neurotrophic and neuroprotective potential. Therefore, transplantation of human amniotic mesenchymal stem cels geneticaly modified by human erythropoietin is a new choice for brain injury treatment.
OBJECTIVE:To observe the effect of transplantation of human amniotic mesenchymal stem cels geneticaly modified byhuman erythropoietin on the functional recovery from brain injury in rats.
METHODS:Eukaryotic expression plasmid pcDNA3.1 carrying erythropoietin was successfuly constructed and transferred into amniotic mesenchymal stem cels culturedin vitro. Expression of erythropoietin was detected using western blot assay before and after transfection. Rat models of middle cerebral arterial occlusion was made and given transplantation of transfected amniotic mesenchymal stem celsviathe tail vein (transfection group). Additionaly, model and simple cel transplantation groups were set in a comparative study.
RESULTS AND CONCLUSION:Findings from western blot detection showed that transfected cels could express human erythropoietin. Compared with the other groups, modified neurologic severity scores, growth-associated protein 43 and aquaporin 9 at mRNA and protein levels were al decreased significantly in the transfection group. Furthermore, the number of cels positive for CM-Dil was highest in the transfectiongroup, folowed by simple cel transplantation group, and lowest in the model group (alP<0.05). Overal findings from this study show that human erythropoietin-modified human amniotic mesenchymal stem cel transplantation promotes neurologic recoveryfrom brain injury through eliciting a reduction in growth-associated protein 43 and aquaporin 9 at mRNA and protein levels as wel as inhibiting cel apoptosis.
