Humanized monoclonal antibody and CARs have became the focus of treatment in adult acute lymphoblastic leukemia (ALL) at the 55th ASH annual meeting.Treating with chemotherapy plus monoclonal antibody will get a develop effect in relapse/refractory adult ALL.More immune-pharmaceutics will be used in clinical trials.

Objective To evaluate the effect of Beijing' s separation of clinic from pharmacy reform.Methods Use difference-in-difference method based on dataset on patients having Urban Worker Medical Insurance from twelve state-owned hospitals.Results The reform incurs a decrease in the outpatient and inpatient expenditure on medicine per visit (30％ and 21％,respectively),a decline in hospital's pharmaceutical ratio (9 percentages and 4 percentages,respectively); reduces the outpatient and inpatient expenditure per visit (19 ％ and 8 ％,respectively),with a decrease in the out-of-pocket part (23％ and 3％,respectively),and a slight increase in the Medical Insurance's part (2％); raises hospital's turnover (11％),outpatient's visits (22％),and inpatient visits (43％).Conclusion The reform encourages physicians to prescribe more scientifically,and hence reduces patient 's expenditure on medicine and hospital's pharmaceutical ratio; leads to a decrease in patience' s expenditure per visit;raises hospital's turnover; and doesn't cause a significant increase in the expenditure from social medical insurance.

Objective To investigate the relationship between dynamic changes of plasma D-dimer and survival rate of the esophageal carcinoma patients pre-and post-operation.Methods 30 cases of normal control group,160 cases of esophageal cancer group( including operation cases n =112),with the gold standard method for the determination of plasma D-dimer.Results There was a link between the level of D-dimer,TNM staging,lymph node metastasis and tumor size in esophageal carcinoma patients.Compared with the preoperation,the plasma D-dimer is significantly elevated 2 years later( t =7.35,P ＞ 0.05 ).Conclusion Before or after the operation,dynamic changes of plasma D-dimer had a relationship with short-term survival rate.

Objective To evaluate the postoperative pain induced by various therapeutic catheters after abdominal surgery.Methods A prospective study was conducted in patients selected based on the inclusion criteria.The general condition of the patients was recorded,and nutritional risk screening was performed.The indwelling of therapeutic catheters after abdominal surgery were recorded,including urinary catheter,nasogastric tube,peritoneal drainage tube,common bile duct drainage tube,wound drainage tube,central venous catheter and peripherally inserted central catheter.The pain caused by each type of catheters was evaluated using visual analog scale at 24,48 and 72 hours after tube/catheter insertion.Results A total of 157 patients were selected,including 70 males and 87 females,aged (60.5 ± 12.5) years,with a body mass index of (23.8 ± 3.2) kg/m2,and a total nutritional risk rate of 42％.According to visual analog scale scores,the degrees of pain due to the therapeutic catheters,in descending order,were as follows:4.9 ± 1.7 for nasogastric tube,3.6 ± 0.9 for wound drainage tube,3.0 ±0.9 for urinary catheter,2.6 ±0.9 for central venous catheter,2.4 ± 1.0 for peritoneal drainage tube,1.9 ± 0.7 for common bile duct drainage tube,and 1.8 ± 0.8 for peripherally inserted central catheter.The catheter-induced pain accounted for (44.9 ± 14.1)％ of the total pain during the hospital stay.Conclusions Nasogastric tube,wound drainage tube and urinary catheter can increase the pain of patients.It is therefore recommended to remove the indwelling tubes as early as possible if only the removal does not harm the outcome of the patient.

ObjectiveTo explore sensitivities and specificities of Nutritional Risk Screening 2002 ( NRS 2002),Subjective Global Assessment (SGA),and Mini Nutritional Assessment (MNA) in the detection of blood prealbumin level.MethodsTotal 126 patients were consecutively enrolled from the oncology departments of three hospitals from November,2010 to March,2011.Nutritional screenings or assessments were performed on the next morning of hospital admission by nutritionists and medical oncologists using NRS 2002,SGA,and MNA.Prealbumin ( ＜ 180 g/L) was used as the reference standard of malnutrition (undernutrition) for assessing the sensitivities/specificities of these tools.ResultsAll 126 patients completed nutritional screening or assessment using the above three tools.The prevalence of malnutrition (undernutrition) determined by NRS 2002,SGA and MNA was 67.0％,46.2％,and 64.8％,respectively.With prealbumin in relation to clinical outcome as the reference standard,the sensitivities ofNRS 2002,SGA,and MNA were 78.2％,58.2％ and 89.1％,and the specificities were 50.0％,72.2％,and 27.8％,respectively.ConclusionsAmong these three tolls,NRS 2002 detects the nutrition risks,whereas SGA and MNA detect malnutrition.Since prealbumin is not an appropriate reference standard,it can not be used for the comparison among the three tools.Nevertheless,NRS 2002 reflects the clinical outcomes,and therefore is suitable for inpatients.

Objective To summarize the perioperative clinical care experience of parenteral and enteral nutrition supports in post-hepatectomy patients.Methods The clinical data of 146 consecutive post-hepatectomy patients in Beijing Hospital were collected and analyzed.For these patients,nutritional risk screening (NRS) 2002 was performed after admission,enteral nutrition support was provided before operation,and enteral and parenteral nutrition supports were provided after operation.Nutritional parameters,clinical outcomes,and nursing methods were evaluated.Results Among these 146 patients,91 patients had≥3 NRS2000 scores,and the remaining 55 patients scored ＜ 3.A total of 118 patients were administrated with enteral and pareteral nutrition;the average enferal nutrition time was 9.6 days,and the average pareteral nutrition time was 5.4 days.The average onset time of passage of gas by anus afar operation was (70.7±17.1) hours.Three patients died,15 patients suffered from infections after operation,and 13 patients experienced other complications.The median hospital stay was 25.5 days.Conclusions Post-hepatectomy patients need take nutritional risk screening after admission and receive appropriate nutritional supports in the perioperative period.It is equally important to strengthen clinical nursing for nutrition support.

Objective To evaluate the impact of the percentage of residual blasts in bone marrow at the end of induction chemotherapy ( T1 ) or during myelosuppression phase (T2) on prognosis of de novo acute myeloid leukemia(AML) (non M3) in 105 cases.To refine AML risk-stratification by combining the percentage of residual blast cells (T1 or/and T2) with cytogenetic data based the South West Oncology Group (SWOG) criteria.Methods The data of 105 de novo AML ( non M3 ) patients hospitalized between January 1st 1999 and February 1st 2008 were retrospectively reviewed.Results were analyzed with SPSS15.0 software.Results ( 1 ) Patients were divided into two subgroups by a cutoff of 5% residual bone marrow blasts at T1 or 12 time point.Patients with percentage of residual bone marrow blast cells <5% had better complete remission (CR) rate,relapse-free survival (RFS) and overall survival (OS) than the patients with percentage ≥5% at T1 or T2.The percentage of residual bone marrow blast cells at T1 was correlated with that at T2.(2) The prognosis of patients with intermediate karyotypes with percentage < 5 % at T1 or T2 was similar to that of the patients with favorable karyotypes.The patients with intermediate karyotypes and percentage of residual bone marrow blasts ≥5% at TI or T2 are defined as a subgroup with prognosis similar to that of patients with unfavorable karyotypes.(3) COX regression analysis showed that the percentage of residual bone marrow blasts at T1 or T2 is an independent prognostic factor of AML.The percentage of residual bone marrow blasts at T1 may be more helpful in prognostification than that at T2.Conclusion AML patients with percentage of residual bone marrow blasts < 5% after induction chemotherapy ( T1 or T2) have better CR rate,RFS,OS than the patients with percentage ≥5% at the same time point.Combination of cytogenetics and percentage of residual bone marrow blasts at T1 or T2 is helpful to divide patients with intermediate karyotypes into two subgroups with different prognosis.Thus,a better decision of treatment strategy can be designed.

Objective To investigate the effect and molecular mechanism of botulinum neurotoxin serotype A (BoNT/A) heavy chain on neuron regeneration. Methods Cell culture, rats, immunofluorescence, SDS-PAGE and western blot, etc. were adopted in this study to explore the alterations of histone-3 acetylation (acetyl-H3 ) by local treatment of BoNT/A heavy chain to spinal cord injury (SCI) in rats (in vivo) or by adding it into cell culture (in vitro). Meanwhile, the relevance of acetyl-H3 to neurite out-growth based on SCI and cell culture with BoNT/A heavy chain application was approached as well. Results The application of BoNT/A heavy chain to cultured Neuro-2a cells increased the level of H3 acetylation. The increase of H3 acetylation was paralleled with the growth of neuritogenesis. Also, the neuronal treatment of BoNT/A heavy chain to SCI promoted the re-growth of neuronal processes surrounding the lesions. The growth of neuronal processes was positively correlated to the level of H3 acetylation. During the periods of BoNT/A heavy chain treatment in vivo or in vitro, the increase of H3 acetylation showed two peaks. Conclusions BoNT/A heavy chain increased the H3 acetylation, which might be one of its neuritogenic mechanisms.

Objective: To investigate the clinical status of lymphoid tissue neoplasms patients with bacteria bloodstream infections, bacteriology and drug susceptibility results, and provide the basis for rational clinical anti-infection option. Methods: A retrospectively analysis of clinical data and bacterial susceptibility test results of patients with bacteria bloodstream infections from September 2010 to December 2014 was conducted. Results: A total of 134 cases including 107 patients with bloodstream infections were enrolled. 84 cases were male, 50 cases were female, the median age was 31 (12-71) years old. 112 cases were agranulocytosis, and 106 cases were severe agranulocytosis (ANC<0.1×10⁹/L) . 27 cases underwent hematopoietic stem cell transplantation, 100 cases received chemotherapy[33 cases with VD (I) CP±L (vincristine+daunorubicin/idarubicin + cyclophosphamide + prednison±asparaginasum) induction chemotherapy, 41 cases with intensive chemotherapy of Hyper-CVAD/MA or MA (mitoxantrone+cytarabine) , 26 cases with other chemotherapy regimens], and 7 cases were infected without chemotherapy. 10 patients discharged from hospital owing to treatment abandoning, 120 cases were cured through anti-infective therapy, 2 patients died of bacteria bloodstream infections, 1 patient died of sudden cardiac, and 1 patient died of GVHD after allogenic hematopoietic stem cell transplantation. A total of 144 strains were isolated, including 108 strains (75.0%) of Gram-negative bacteria and 36 strains (25.0%) of Gram-positive cocci. The susceptibility of Gram-negative bacteria to the carbapenems was 98.00%, and the adjustment treatment rate of carbapenems was 3.0%. The susceptibility of Gram-negative bacteria to the other antibiotics was 60.30%, and the adjustment treatment rate was 90.5%. The susceptibility of Grampositive cocci to the carbapenems was 49.3%, and to glycopeptides and linezolid was 100.0%. Comparing all patients’empirical use of antimicrobial agents with the drugs susceptibility results of blood cultures, 80.1% of the patients’initial drug selection was sensitive. Conclusion The lymphoid neoplasms patients experienced bacteria bloodstream infections most often after receiving the chemotherapy regimens of treating acute lymphoblastic leukemia. The majority type of bacteria was Gram-negative bacteria. Drug susceptibility test showed that susceptibility of Gram-negative bacteria to the carbapenems was the highest, and the treatment adjustment rate was obviously lower. The susceptibility of Gram-positive cocci to glycopeptides and linezolid was high, and which could be applied to the patients with Gram-positive cocci sepsis on basis of susceptibility results in general.

Objective: To investigate the prognostic significance of detection of minimal residual disease after first induction treatment (MRD₁) in adult acute lymphoblastic leukemia (ALL) patients treated with autologous stem cell transplantation (auto-HSCT). Methods: The clinical data of 87 ALL patients who underwent auto-HSCT during February 2006 to April 2017 with MRD₁ detection data by flow cytometry were analyzed retrospectively. The relationship between MRD₁ and relapse and survival of ALL patients after auto-HSCT was studied. Results: Of 87 patients, 26 (29.9%) were MRD₁ positive. The proportion of high-risk immunophenotype (pro-B, pro-T, pre-T, mature T) was significantly higher in MRD₁-positive patients than that in MRD₁ negative patients (34.6% vs 14.5%, P=0.038). There was no significant difference between positive and negative MRD₁ patients at age, sex, lineage (T/B), immunophenotype (standard risk/high risk), high white blood cell count (B-ALL>30×10⁹/L or T-ALL>100×10⁹/L), high-risk chromosome/gene ratio, the time from first complete remission to transplantation and pre-treatment regimen. The 5-year overall survival (OS) and leukemia-free survival (LFS) in MRD₁ negative and positive patients were 72.7% vs 47.3% (P=0.004) and 75.7% vs 29.6% (P<0.001), respectively. Multivariate analysis showed that positive MRD₁ was an independent risk factor for OS (HR=3.007, 95% CI 1.256-7.200, P=0.013) , and positive MRD₁ and high-risk immunophenotype were risk factors for LFS (HR=3.986, 95% CI 1.813-8.764, P=0.001; HR=2.981, 95% CI 1.373-6.473, P=0.006) . Conclusions Auto-HSCT could not reverse the poor prognosis of MRD₁ positive patients. Auto-HSCT treatment is optional for patients with MRD₁ negative and maintaining MRD₁ negative status during intensive therapy.
