Second primary malignancies are more likely to occur in the multiple myeloma patients .Most of them are Acute myeloid leukemia ( AML) or Myelodysplastic syndrome ( MDS) .The incidence in male or those multiple myeloma patients who is less than 60 years old are more than female or those multiple myeloma patients who are bigger than 60 years old.In recent years,studies of multiple myeloma secondary to leukemia and other tumors are gradually increasing ,but the mechanism and treatment are still unclear .These diseases have the follow-ing characteristics such as progress rapidly ,high mortality rate and low complete remission rate after chemothera-py.

Objective To observe the effects of respiratory training on pulmonary function in the patients with chronic obstructive pulmonary disease(COPD). Methods A total of 74 patients with COPD were recruited and randomly divided into a treatment group and a control group with 37 subjects in each.The treatment group re-ceived respiratory training including lip-contracting breathing,abdominal breathing and breathing exercises for 6 months in addition to routine medical treatment.The control group received only routine medical treatment.Pulmona-ry function was evaluated before and after treatment. Results After treatment,both groups improved in terms of all the pulmonary function measures,showing increased vital capacity(VC),forced expiratory volume after 1 s(FEVl),peak forced expiratory flow rate(PEFR),as well as forced expiratory flow at 25%of Vcmax(V25),de-creased residual volume and residual volume as a percentage of total lung capacity(RV/TCL).The difference be-tween the two groups was significant with regard to the extent of improvement. Conclusion Respiratory training can improve the pulmonary function of COPD patients.

Objective:To compare the pharmacokinetics and relative bioavailability between matrine sustained release tablet,matrine conventional capsule and matrine injection. Methods: Dogs were given single oral dose and multiple doses of matrine sustained release tablet, capsule or injection in a randomized crossover way. Matrine concentrations in dog plasma were determined by RP-HPLC method. Results: The results showed that the t max and c max were 300 min and (5.088?0.490) ?g/ml for matrine sustained release tablet, (85?12) min and (6.360?0.215) ?g/ml for the conventional capsule, and 10 min and (6.500?0.404) ?g/ml for the injection. The relative bioavailability of the sustained release tablet was (153.7?9.4)% compared with that of the conventional capsule; the absolute bioavailability of the sustained release tablet was (73.5?14.2)% compared with that of the injecetion. The in vivo absorption rate of the sustained release tablet was significantly correlated with the in vitro release rate(r=0.981 2,P

Objective Human serum albumin ( HSA) is a kind of plasma protein , which can transport various small molecu-lar substances to the body.A disulfide bond breaking strategy is used to fabricate HSA-curcumin nanoparticles(NPs-CCM) in order to improve the solubility and tumor targeting capability of curcumin . Methods NPs-CCM were fabricated with dithiothreitol as the re-ducing agent .The size and shape of the nanoparticles were observed with high resolution electron microscopy .We explored the change of hydrophobic region during the process of degeneration of albumin , the releasing behavior in the solution and the tumor targeting capa-bility in vivo and vitro of NPs-CCM. Results The diameter of NPs-CCM was about 150 nm.The determination of surface hydropho-bicity showed that ANS fluorescence intensity decreased gradually as the extension of degeneration time , at the time 0 min, 2 min, 5 min and 10 min, ANS relative fluorescence intensity was 5492(5432-5673), 2486(2319-2878), 1998(1904-2317), 1503 (1280-1584) respectively.The hydrophobic region of albumin gradually reduced during the degeneration time .The curcumin re-leased from NPs-CCM amounted to about 50% within 40 h, and the NPs-CCM can be absorbed by tumor cells and accumulation in tumor tissue. Conclusion Albumin can improve the solubility and tumor targeting capability of curcumin , and it has potential clinical application value.

OBJECTIVE:To evaluate the efficacy and safety of Xuebijing injection in the adjuvant treatment of children with perforated appendicitis. METHODS:72 children with perforated appendicitis in the Dept. of Pediatric General Surgery of our hospi-tal were enrolled into a prospective clinical trial,and randomly divided into experimental group (n=36) and control group (n=36). Both groups received the emergency surgery and anti-infective treatment;experimental group had additionally given Xuebijing injection. The white blood cell count (WBC),C-creation protein (CRP) and procalcitonin (PCT),liver and kidney function and hospitalization time before and after treatment were collected and adverse reaction. RESULTS:The WBC in experimental group af-ter 3 and 6 d of treatment was respectively(13.6±3.4)×109 L-1 and(9.1±4.2)×109 L-1,CRP was respectively(52.7±13.6)mg/L and(8.5±3.3)mg/L,the PCT(0.3±0.2)ng/ml,and the hospitalization time after 3 d were lower than control group,with signifi-cant difference(P<0.05). There were no significant difference in the liver and kidney function(P>0.05). There was 1 case with itch of skin but with no severe ADR. CONCLUSIONS:Xuebijing injection in the adjuvant treatment of children with perforated ap-pendicitis is safe and effective.

Objective To investigate the regulatory effects of probiotics on ghrelin and their pro-tective effects on pulmonary function of children during acute lung injury.Methods Fifty children with acute lung injury were recruited form Henan Provincial People′s Hospital during 2010 to 2013 and randomly divided into two groups.In addition to regular therapy, those who received probiotics treatment were set up as the probiotics treatment group and the others were considered as the control group.Levels of ghrelin, sur-factant protein A( SP-A) , TNF-αand IL-6 in serum samples were measured before and 10 days after the cor-responding treatments.Each patient was analyzed by pulmonary function test and echocardiography.The vol-ume to peak expiratory flow ( VPEF) , ratio of time to reach peak tidal expiratory flow to total expiratory time ( TPTEF/TE) , mean arterial pressure ( MAP) and pulmonary artery pressure ( PAP) were recorded for sta-tistical analysis.Results The levels of SP-A, TNF-αand IL-6 in serum samples from the probiotics treat-ment group were decreased on day 10 as compared with those of the control group [(195.9±54.3) ng/ml vs (245.5±56.4) ng/ml, (382.0±56.4) pg/ml vs (440.7±46.8) pg/ml, (221.5±62.6) pg/ml vs (303.5 ±83.9) pg/ml;P<0.05] .Children from the probiotics treatment group showed higher values of VPEF and TPTEF/TE on day 10 as compared with those without probiotics treatment [(25.3±4.5) ml vs (23.8±4.6) ml, (29.5±4.3) %vs (26.8±4.7) %;P<0.05].Treatment of children with probiotics increased MAP and decreased PAP [(74.5±6.7) mmHg vs (71.9±6.9) mmHg, (25.5±6.4) mmHg vs (29.1±6.2) mmHg] .The levels of ghrelin in patients received probiotics treatment were higher than those of children without probiotics treatment [(329.3 ±49.6) pg/ml vs (296.6 ±48.5) pg/ml].The levels of ghrelin showed negative correlations with the levels of SP-A, TNF-α, IL-6 and PAP on day 10, but positive correla-tions with TPTEF/TE and MAP (P<0.05).Conclusion Use of probiotics to children with acute lung inju-ry could regulate the level of ghrelin, alleviate the inflammation of lungs and improve the recovery of lung function and circulation.Therefore, probiotics treatment had positive effects on the protection of pulmonary function.
