The prognosis for patients multiple myeloma(MM)has improved substantially over the past decade with the development of new,more effective chemotherapeutic agents and regimens that possess a high level of anti-tumor activity.In spite of this important progress,however,nearly all MM patients ultimately relapse,even those who experience a complete response to initial therapy.This summarize provided detailed recommendations on management of relapsed disease,with sections dedicated to diagnostic evaluation,determinants of therapy,and general approach to patients with specific disease characteristics.In addition,the article provided a summary of evidence from clinical trials that have significantly impacted the field,including those evaluating conventional therapies,as well as both autologous and allogeneic stem cell transplantation.Finally,perspective is provided regarding new agents and promising directions in management of relapsed MM.

Objective To observe the performances of autophagy and inlfammatory cytokines in wounded mice skin at different time, and to explore the relationship between these performances and the duration of wound in the mice. Methods RT-PCR and West-blot methods were used to detect the genetic expression and protein expression of Beclin-1, LC-3, IL-1α, IL-1β, and MCP-1 in wounded skin of the mice. Results After the mice’s skin was wounded, the level of IL-1a and IL-1β genetic and protein expression increased early, the peak was found after 12 hours, and then decreased; the expression of MCP-1 began to increase after 6 hours and it reached peak after 48 hours, then decreased; while the genetic and protein expression of LC3 and beclin-1 began to increase after 6 hours, and the peak was seen after 24hours, then decreased too. Conclusion After the mice’s skin was wounded, the starting and the peak of the expression of autophagy came later than those of inlfammatory cytokines, it is found the level of the expression of inlfammatory cytokines was showing a downward trend when the expression of autophagy reached the peak. This performance may be caused by increasing inlfammatory cytokines in the tissue of the incised wound, which activated the autophagy, and when the level of autophagy reached a certain degree, it could suppress the excessive inlfammatory reaction. So the autophagy and the inlfammatory cytokines interact regularly after the mice’s skin was wounded, and such interaction offers us a reference to infer the injury time after injury.

Objective:To evaluate the safety and feasibility of root canal therapy in leukemia patients before bone marrow transplantation.Methods:15 root canal therapy of teeth with chronic periapical diseases were performed in 15 patients with leukemia before bone marrow transplantation.Diameters of the shaded area of periapex were all less than 0.5 cm.The root canal therapy was done at appropriate time,restricted hemateikon(neutrophil counts range from 3.0?109/L ~10?109/L,platelet counts more than 50?109/L),all the teeth were done with root canal therapy according to the principle of root canal therapy.All the patients were monitored by return visit after transplantation.Results:It did not happen any odontogenous complication with 15 patients during the bone marrow transplantation period.The periapical diseases of 15 teeth have been well controlled after root canal therapy.Conclusion:Teeth with chronic periapical diseases of patients with leukemia before bone marrow transplantation can be preserved after adequate root canal therapy and the root canal therapy is safe.

Objective:To investigate the pluripotency of human embryonic stem cells in vitro.Meth-ods:Human embryonic stem cells were cultured in suspension without feeder layers and bFGF in medi-um.mRNAs of different types of cells were analyzed by RT-PCR.Results:When Human embryonicstem cells were cultured in suspension without feeder layers and bFGF in medium,they formed floatingaggregates termed embryoid bodies(EBs),in which many precursors and functional cells were detectedby RT-PCR,such as neural and islet precursors,neurons,insulin-secreting cells,glucagon-secretingcells and liver cells et al.Conclusion:Human embryonic stem cells are able to form embryoid bodiesnaturally in vitro which express specific markers of many types of precursors and mature functional cells.

Objective To observe the curative effects of carboprost tromethamine injection in treatment of postpartum hemorrhage due to uterine inertia.Methods The clinical data of 118 patients with postpartum hemorrhage due to uterine inertia were analyzed retrospectively.The patients were divided into control group (68 cases) and observation group (50 cases) by treatment method.The patients in control group were given conventional treatment while the patients in observation group were given carboprost tromethamine injection on basis of conventional treatment.The postpartum blood loss after 2,24 h after treatment,the third labor time and therapeutic effects in two groups were recorded and compared.The patients in control group took carboprost tromethamine injection if conventional treatment did not work and all patients should have surgery immediately if repeatedly carboprost tromethamine injection were invalid; adverse reactions of using carboprost tromethamine injection were closely watched.Results The postpartum blood loss after 2,24 h after treatment in control group was (676 ± 86),(751 ± 70) ml,which was higher than that in observation group [(238 ± 62),(281 ± 56) ml],and there was significant difference (P ＜ 0.05).The third labor time in control group was (5.1 ± 1.9) h,which was longer than that in observation group [(2.1 ± 1.4) h],and there was significant difference(P＜ 0.05).After conventional treatment with 47 patients stopped bleeding in control group,and the effective rate was 69.1％ (47/58),while the effective rate in observation group was 96.0％ (48/50),and there was significant difference (P ＜ 0.05).Twenty-one patients in control group accepted carboprost tromethamine injection after treatment,while the traditional therapy did not work,and the effective rate increased to be 95.2％ (20/21).Among carboprost tromethamine injection treatment of 71 patients,2 cases' blood pressure increased,2 cases had facial blushing,1 case with mild headache,3 cases of diarrhea and 3 cases of nausea and vomiting (a total of 11 cases),and the incidence rate was 15.5％ (11/71),which was relatively minor.All patients were given symptomatic treatment and all rell eased within 24 h,and there were no other serious adverse reactions.Conclusion Using carboprost tromethamine injection to treat postpartum hemorrhage due to uterine inertia has more remarkable curative effects and higher clinical safety,which is worthy of clinical promotion.

Objective To observe the effects of ganoderma lucidum polysaccharide(GLP) on intestine mucosal barrier function and tumor necrosis factor-α(TNF-α)in hemorrhagic shock rabbits. Methods Thirty healthy Japanese white rabbits were divided into three groups by random number table:sham operation group, resuscitation/reperfusion with normal saline(NS)group(NS group)and resuscitation/reperfusion with GLP group (GLP group). The hemorrhagic shock models were reproduced by being bled from the femoral artery to the mean arterial pressure(MAP)of 30-40 mmHg(1 mmHg=0.133 kPa)within 10 minutes and kept maintaining at this MAP level for 40 minutes. Then,the anti-shock therapy was given. The rabbits in NS group were immediately and quickly resuscitated with reperfusion of their shed blood and intravenous drip of NS in a volume equal to 2-fold of the volume of the shed blood. The rabbits in GLP group were dealt with the same means as NS group except NS was replaced by 1%GLP. The rabbits in sham operation group were only cannulated and maintained in a status of blood pressure measurement,but without bloodletting and resuscitation. The TNF-α content,the number of positive bacterial culture of blood bacteria were observed at the time before shock(S0),40 minutes after shock(S40)and 40 minutes and 90 minutes after resuscitation/reperfusion(R40,R90),respectively in the three groups. The serum endotoxin level and the TNF-αcontent in intestinal mucosa were examined at R90. Under the light microscopy,the pathological changes of intestinal mucosa were examined,and the score of the mucosal damage was evaluated by the criteria of Chiu method. Results ①Before shock,the results of blood bacterial culture of all animals in three groups were negative. With the extension of time,the positive rates of blood bacteria were increased gradually at R40 and R90 in NS and GLP groups,showing increment of bacterial translocation,but the levels at R40 and R90 were significantly lower in GLP group than those in NS group at the same time points(number of rabbits at the time of R40:2 vs. 4,at the time of R90:4 vs. 6,both P<0.05). Escherichia coli was the most common positive bacteria in the blood;the other positive bacteria were sequentially less and less,Enterococcus,Lactobacillus acidophilus and Staphylococcus aureus. Compared with sham operation group,the serum endotoxin levels of NS and GLP groups were significantly higher at R90(kU/L:1.823±0.963,1.361±0.529 vs. 0.064±0.036,both P<0.05). ② Under the light microscope,it was shown that in NS group the mucosal villi were edematous,the sub-epithelial space was widened,and there was infiltration of neutrophils and lymphocytes. The damage of intestinal mucosa in GLP group was obviously milder than that in the NS group. The Chiu scores of GLP and NS groups were significantly higher than that of sham operation group;meanwhile,Chiu score of GLP group was lower than that of NS group(1.44±0.64 vs. 3.79±1.23,P<0.05).③Along with extension of ischemia and reperfusion time,TNF-α contents in NS and GLP groups were gradually increased significantly,the peak value being at R90,meanwhile,the levels in both groups were significantly higher than the level of sham operation group,and the TNF-α content in plasma of GLP group was lower than that of NS group〔A value:33.350±7.950 vs. 85.080±4.330,P<0.05〕. Compared with sham operation group,the TNF-αcontents in intestinal mucosa of NS and GLP groups were higher than the level in sham operation group,meanwhile,TNF-αcontent in intestinal mucosa of GLP group was lower than that of NS group〔A value:96.38±8.59 vs. 167.73±12.32, P<0.05〕. Conclusion In the salvage process of resuscitation-reperfusion,GLP can protect intestinal barrier function in rabbits with hemorrhagic shock,and its effect may be related to antagonizing the release of TNF-α.
