[Objective] To study the role of scaffold internal three dimensional structure of on vascularization of ?-TCP biomaterials in vivo.[Method]Twenty four adult rabbits were selected for operation.Two different three-dimensional structure ?-TCP biomaterials(wafer ?-TCP,the pore diameter was from 400 ?m to 500 ?m,the pore inter-connection diameter was 120 ?m;granulation ?-TCP,the particle diameter was from 100 ?m to 200 ?m)were implanted separately into fascia lumbodorsalis of every rabbit.The specimens were harvested in 1,2,4,8 weeks after surgery for histology,scanning electronic microscope(SEM)and SPECT studies in order to observe the vascularization of two different structure ?-TCP biomaterials in vivo.[Result]The biocompatibility of two different ?-TCP biomaterials was favourable.Only a few of immature blood capillaries were detected in some peripheral pores of two different biomaterials in one week after surgery.In four weeks of implantation,the result of histology indicated that the wafer artificial bone had vascularized completely.The number and lumens of blood vessel had increased.The peripheral blood vessel had been mature,showing vascularization crest-time.In eight weeks after sugery,there was no more increase of the number of blood vessel,while the lumens of blood vessel had increased.The mature capillaries were observed by chance.To compare with the wafer artificial bone,the vas cularization rate of the granulation artificial bone biomaterials was slower,and the number of blood vessel was less.On the other hand,the smaller lumens diameter and the infant structure existed in most of blood capillaries.Many blood vessels were not mature in four weeks,the vascular occlusion in some pores was detected.[Conclusion]The pore interconnection pathway in scaffolds is a key factor for vascularization.In other words,the higher density of pore interconnection pathway can induct more complete vascularization in scaffolds,and the diameter can restrict the lumens of blood vessel diameter.

Objective: The exogenous gibberellin (GA) and ethylene (ET) treatment can improve the medicinal ingredients of Salvia miltiorrhiza. Interestingly, many reports pointed out that WRKY transcription factors played an important regulatory role in these treatment responses. However, whether the SmWRKY mediate these treatment signalings in S. miltiorrhiza remains largely elusive. Methods: qRT-PCR was used for SmWRKY42-like in response to exogenous GA and ethephon (Eth) treatment. The subcellular location of SmWRKY42-like was transiently transformed into onion epidermal cells by particle bombardment. The self-activating activity of SmWRKY42-like was verified in AH109 yeast strain. Results: SmWRKY42-like was a WRKY family gene in S. miltiorrhiza. The subcellular localization and transcriptional activity results of the SmWRKY42-like protein indicated that SmWRKY42-like mainly enriched in nucleus and might be a transcription factor in S. miltiorrhiza. In the meantime, the SmWRKY42-like gene significantly responded to exogenous GA and Eth treatment. Conclusion: These results collectively indicated the SmWRKY42-like gene functions, as an important hormone-responsive gene, might play a potentially role in ET and GA signaling pathways.

Objective To investigate the effects of different dose of tranexamic acid in fibrinolysis during liver transplantation. Methods Sixty ASA Ⅱ~ Ⅳ liver transplant recipients, were randomly, double-blind assigned to one of 3 groups (n = 20): group control (group C), group tranexamic acid 1 (group T1) and group tranexamic acid 2 (group T2). The patients in group C received a loading dose of normal saline 10 mL, then continued infuse normal saline at 20 mL/h until neohepatic phase 120 min, while in other two groups, patients received a loading dose of tranexamic acid 1 g, totally 10 mL, followed by continuous infusion at 10 mg/(kg·h) in group T1 or 20 mg/(kg·h) in group T2 until neohepatic phase 120 min. Prothrombin time, fibrinogen, fibrin degradation product and D-dimers were measured before operation (T0), 120 min after the skin incision (T1), nonhepatic phase 30 min (T2), neohepatic phase 120 min (T3). Blood loss, fresh frozen plasma dosage, fibrinogen dosage and thromboembolic events were recorded. Results The plasma concentration of fibrin degradation product and plasma concentration of D-dimers were different in the 3 groups, group T2< group T1 0.05). Conclusions Continuous infusion of tranexamic acid can inhibit fibrinolysis during liver transplantation. No adverse event of thrombosis was detected. Larger dose of tranexamic acid can reduce blood loss and fresh frozen plasma transfusion.

Objective To evaluate and monitor the efifcacy of GnRH analogs (GnRHa) therapy. Methods Thirty girls with central precocious puberty diagnosied by LHRH stimulation test were treated with GnRHa for 6-24 months. The LHRH stimula-tion test were performed again at 3 months after initiation of therapy and then every 6 months during treatment. The relationship of peark LH and clinical suppressing pubertal (including Turner stage, bone age, grwoth speed) were compared. The monitor effect of peak LH to efifcacy of GnRHa were eveluated. Results Ninety LHRH stimulation tests were performed, only 7 cases were found to have clinical pubertal development. After 6 months treatment, the base LH level of thirty girls (0.48±0.20) IU/L was signiifcantly lower than that before the treatment (0.75±0.35 IU/L) (P=0.000). The correlation coefifcient between base LH and peak LH was 0.62. The best correlation between clinical suppressing pubertal and LHRH stimulation test was achieved when peak LH was less than 2 IU/L (85.7%sensitivity, 100%speciifcity). Conclusions Base LH value can be used in preliminary as-sessment of the efifcacy of GnRHa therapy for girls with central precocious puberty. The peak LH less than 2 IU/L can be as the indicator of treatment efifcacy.

AIM: To establish HPLC fingerprint of Sishen Pill and a determination of main component of Sishen Pills(Fructus Evodiae, Semen Myristicae, Fructus Psoraleae, etc.) by HPLC. METHODS: The samples were extracted with the solvent methanol. The separation was performed on YWG-C 18(4.6mm?250mm, 10?m) column with water- methanol-acetonitrile as a mobile phase gradient elution. The flow rate was 1.0mL?min -1, the column temperature was at 30℃ and the wavelength of UV detector was at 225nm. RESULTS: There are 21 higher peaks and 12 marker peaks in the fingerprint of eight batches of samples. For evodiamine, the regression equation was Y=147.37X+1186.32, r=0.9999, the liner range was from 5 to 1000?g?mL -1 and the recovery was 99.83%. For rutaecarpin, the regression equation was Y=101.19X+279.81, r= 0.9999, the liner range was from 4.5 to 900?g?mL -1. The recovery was 98.72%. CONCLUSION: The quality standard of Sishen Pill was established firstly. It can be used for quality cantrol of Sishen Pill.

OBJECTIVE To clarify the features of nosocomial infections for patients with multiple myeloma(MM).METHODS One hundred and seventy eight cases of MM treated in our hospital from Oct 1982 to Dec 2006 were analyzed retrospectively.RESULTS Eighty five patients(47.8%) suffered from nosocomial infections.The nosocomial infection took place more frequently on respiratory tract.Elder,granulocytopenia,hypoproteinemia,severe anemia,and diabetes were the risk factors.Totally 91 pathogens were isolated.Gram-negative bacilli accounted for 45.1%,and were the major pathogens.Fungi accounted for 37.4% and Gram-positives accounted for 17.6%.The ESBLs producing strains accounted for 31.6% in Klebsiella pneumoniae and Escherichia coli.Vancomycin resistant strains were found.The top one of fungi presented organism was the Candida albicans.CONCLUSIONS Nosocomial infections for patients with multiple myeloma has a high incidence.There are many risk factors.The resistance of commonly encountered bacteria to antimicrobial agents is a serious problem.Immunity protection and the rational use of antimicrobial agents should be emphasized.
