The treatment of multiple myeloma has become possible in the era of novel agents. Novel agents have dramatically improved the response rates of multiple myeloma (MM) and have extended the survival of patients even if MM remains an incurable disease. De-termining the treatment goals of MM has become a major challenge for clinicians in the era of novel agents. Many results show the correlation between response depth and patients' survival. Complete remission (CR), stringent CR, phenotypic CR, and CRs at the molecular and PET-CT levels are being explored and becoming the goals of MM treatment. Doctors should balance efficacy with adverse effects in daily clinical practice to avoid the blind pursuit of a high and deep response rate.

Objective To investigate the relationship of vascular endothelial growth factor(VEGF)with the invasion and metastasis of non-Hodgkin lymphoma.Methods The levels of serum VEGF was measured by enzyme linked-immunoadsorbent assay(ELISA).Comparing the parameters between NHL group and the control group.Compared the parameters with different groups divided by clinical stage,the effect of the treatment,the level of plasma LDH and effect of treatment.Analyzed the correlation of the levels of serum VEGF and plasma LDH in patients of NHL.Results The levels of serum VEGF are remarkablely higher in patients than that in the control group(P＜0.05).The levels of serum VEGF in the group of Ⅲ,Ⅳ clinical stage are higher than that in the group of Ⅰ,Ⅱ clinical stage,but no significant difference(P＞0.05)were observed.The level of serum VEGF is higher in the group of none CR than the group of CR(P＜0.05).The level of serum VEGF is higher in the group of non-normal level of plasma LDH than group of normal LDH level(P＜0.05).The levels of VEGF and LDH are significantly correlated each other(P＜0.01).Conclusion The angiogenesis are important for tumor metastasis in patients of NHL.The serum VEGF can be used as prognosis parameters in patients with NHL.

Objective To study the expression of hepatocyte growth factor (HGF) in placenta from normal pregnancy and pregnancy induced hypertension (PIH) and the effect of HGF on angiogenesis in placenta. Methods Immunohistochemistry was used to determine the location and intensity of HGF staining in placenta from 20 cases of normal pregnancy and 58 cases of mild,moderate and severe PIH groups. HE staining was used in order to count the number of the vessles. Results HGF mostly were expressed in villous core mesenchymal cells,less in decidual cells . Intensity of HGF immnostaining in villous mesenchymal cells was significantly reduced in the severe PIH group compared with the normal group(H=7.395,P=0.003),while there were no statistical differences between the mild,moderate PIH group and the normal group (H=0.869,P=0.351,H=0.017,P=0.896) .The count of vessels reduced in severe PIH (F=10.676,P=0.008). There was positive correlation between the expression of HGF and the count of vessels in villous(r=0.246,P=0 030). Conclusion These results suggested that HGF is secreted mainly by villous core mesenchymal cells in human placenta and the reduction of HGF in PIH may be responsible for the impaired vascularization in PIH.

Objective To establish an animal model of sacral nerve root avulsion in rats and e-valuate its efficiency. Methods A total of 20 adult SD rats (either sex) were chosen at random to es-tablish the sacral nerve root avulsion model by avulsing the fight L4-6 nerve roots out of intervertebral fo-ramina without laminectomy. The left side was set as control group. The models were evaluated in aspects of survival rate, Basso-Beattie-Bresnahan (BBB) scores, somatosensory evoked potential (SEP), horse radish peroxidase (HRP) tracing, bilateral weight and cross section area (CSA) of muscle biceps femo-ris, fiber of triceps surae and anterior tibial muscle. Results Of all, 19 rats were survived but one died, with survival rate of 95.0%. The BBB score was (10.78+3.15) points in experimental group and 21 points in control group. The success rate of establishing animal model was 89.5% ,for there detected no SEP in bilateral cerebral cortex of the wounded extremity of 17 rats. HRP showed positive reaction in the spinal segment of L4-6 in two rats but negative in 17, with success rate of 89.5%. There was statistical difference in aspects of weight and muscle fiber CSA of double biceps femoris, triceps surae and anterior fibial muscle between experimental group and control group. Electron microscope found denervation chan-ges including muscle fiber atrophy, nucleus shifting to (center and muscle satellite cell. Conclusion A-vulsion of L4-6 sacral nerve root out of vertebral canal is a feasible and ideal method to establish the avui-sion model of sacral nerve root injury in rats.

BACKGROUND:Palatal rugae assist for consonantal formation;however,effect of palatal rugae on phonetics has been previously reported to be involved in different complete denture base plates of recipients.OBJECTIVE:To qualitatively analyze the effe-cts of different palate base plate morphology on phonetics of edentulous jaw patients using a computerized speech lab.DESIGN,TIME AND SETTING:A contrast study was performed at the Department of Stomatology,Beijing Hospital of Healthy Administration,and at the Department of Otorhinolaryngology,Beijing Friendship Hospital affiliated to Capital Medical University between February 2007 and February 2008.PARTICIPANTS:Ten edentulous jaw patients wore complete denture with smooth surface and palatal rugae complete denture base.METHODS:Spike,voice onset time and transition of 10 edentulous iaw patients were measured by computerized speech lab when/da/,/ta/,/sa/,and/na/were pronounced.MAIN OUTCOME MEASURES:Spike.voice onset time and transition.RESULTS:Spikes were observed in all syllables.When/da/and/ta,were pronounced.voice onset time in the smooth surface group was significantly shorter than palatal rugae group(P<0.05):voice onset time of/d/and/t/in the palatal rugae group was similar to normal value(P>0.05).When/da/and/ta/ were pronounced,transition frequency in the smooth surface group was significantly lower than palatal rugae group(P<0.05),while that in the palatal rugae group was similar to normal value(P>0.05).CONCLUSION:As an anatomical landmark,palatal rugae contribute to phonetic restoration and consonant articulation of edentulous jaw patients.Computerized speech lab can quantitatively analyze phonetic changes after complete denture restoration and may be used as guidance for clinical dental prosthetics.
