Objectives To investigate the efficacy and toxicity of bortezomib based combination therapy for Chinese patients with relapsed or refractory multiple myeloma(MM),and to determine the combination regimen,dosage and cycles in application of bortezomib for MM therapy.Methods Forty-six patients with refractory or relapsed myeloma were treated with bortezomib(1.3 mg/m2)as an intravenous bolus twice weekly for 2 weeks on day 1,4,8,and 11 in a 3-4 week cycle,in combination with dexamethasone,dexamethasone plus thalidomide, CD(C-cytoxan,D-dexamethasone),MD(M- mitoxsnteone),DCEP(E-etoposide,P-platinol),and DT-PACE regimens(T-thalidomide,A-adriamycin). Response to bortezomib was evaluated according to the criteria of the International Myeloma Working Group (IMWG)before initiation of each cycle.Adverse events were graded according to the National Cancer Institute Common Toxicity Criteria,version 3.0.Forty-nine matched patients with relapsed and refractory MM who received thalidomide based combination therapy were used as a historical control group.Results Among 43 of the 46 patients whom could be evaluated,the overall response rate was 72.1%(the control group was 51.0%,P＜0.05),including complete response in 5 patients(11.6%),very good partial response in 12 patients(27.9%),and partial response in 14 patients(32.6%).The overall response rate after one and two cycles was 30.2%and 58.1%(P＜0.05),respectively.The frequent adverse events were thromboeytopenia(62.8%),fatigue(55.8%),nausea(51.2%)and peripheral neuropathy (30.2%);all of the events could be tolerated.The most common adverse event in the control group was constipation(69.4%),followed by fatigue(59.2%)and dizziness(46.9%).Conclusions Bortezomib based combination therapy is a new effective therapy in relapsed or refractory myeloma patients with a higher response rate and difierent toxicities as compared with thalidomide based combinations.

Objective:To evaluate the benefit of autologous stem cell transplantation (ASCT) as a consolidation therapy in the survival of multiple myeloma (MM) patients at different risks. Methods:A total of 67 MM patients who received ASCT as consolida-tion therapy between August 2006 and July 2011 were enrolled in the retrospective study. The cases were divided into three risk groups on the basis of the International Staging System and fluorescence in situ hybridization. Another 67 patients who accepted consolidation chemotherapy at the same period were selected as case-paired controls matched in terms of age, sex, optimal response after induction, and risk stratifications. All the patients received bortezomib-and/or thalidomide-based induction therapies. Results:No statistical differ-ences in non-complete remission (nCR)/complete remission (CR) rate were observed between the ASCT and chemotherapy groups (44.8%vs. 37.3%, P=0.380) after the induction therapy. The progression-free survival (PFS) was longer in the ASCT group than in the chemotherapy group (32.4 months vs. 15.1 months, P<0.001). The overall survival (OS) was longer in the ASCT group than in the che-motherapy group (58.8 months vs. 42.1 months, P=0.009). both the PFS (median:30.5 months vs. 11.2 months, P<0.001) and the OS (median:85.5 months vs. 34 months, P=0.015) rates were significantly prolonged in the high-risk subgroup after ASCT. In the interme-diate-risk subgroup, neither PFS nor OS showed any significance after ASCT (P>0.05). In the low-risk subgroup, only PFS was extend-ed (median: 34.8 months vs. 17.6 months, P=0.012) after ASCT, without significant improvements in the OS (P>0.05). Conclusion:The MM patients obtained cytogenetic high-risk benefits mostly from ASCT consolidation after inductions based on novel agents.

To understand the family sex education for young children in rural areas of Sichuan province and analyze the influencing factors. A multi-stage random sampling method was used to select 2246 parents of kindergarten children from rural areas in Sichuan province for a questionnaire-based survey.The Chi-square test and Logistic regression model were used for data analysis. It was found 1132(52.33%)parents had implemented family sex education for young children and 1031(47.67%)had not.Young children having asked sex-related questions(=1.536,95%=1.257-1.878),parents thinking that early childhood sex education is necessary(=3.691,95%=2.029-6.717),and parents having the intention to know early childhood sex education(=1.700,95%=1.274-2.269),and kindergarten having implemented early childhood sex education(=3.316,95%=2.515-4.372)were promoting factors for parents to conduct early childhood sex education,whereas a total annual household income at the middle level(=0.664,95%=0.456-0.968)was a hindering factor for parents to conduct early childhood sex education. Parents of young children in rural areas of Sichuan province have poor awareness of sex education,and the proportion of parents who have never conducted sex education for children is high.The total annual income of the family,whether the children have asked about sex-related questions,parents' attitude towards early childhood sex education,and whether the kindergarten has conducted the early childhood sex education are important factors that influence the level of children's family sex education.

OBJECTIVETo investigate the relationship between the clinical features, pathogenesis, immunophenotype, different classification models and prognosis in Chinese patients with diffuse large B-cell lymphoma (DLBCL).

METHODSA total of 147 patients with DLBCL who were treated with CHOP-like or R-CHOP were subjected to analysis. Standard two-step Envision method of immunohistochemical staining was used to assess the expression of CD10, Bcl-6, MUM1, FOXP1, GCET1, CD5, Bcl-2, Ki-67, then according to Hans algorithm, Choi algorithm and Molecular markers, we compared the differences of their prognoses.

RESULTS(1) Kaplan-Meier univariate analysis of the clinical data of 147 DLBCL patients found that the 3-year overall survival (OS) rates were better in early stage (P=0.032), low IPI score (P=0.001), less than one extranodal involvement (P=0.014), and complete remission (P<0.01). The prognoses had no significant difference in terms of gender, age, LDH, B symptoms and treatment options (P value> 0.05). (2 )For Hans model, GCB group had 42 cases, the ABC group 85 cases; GCB were 47 cases, ABC 80 cases (according to Choi model). Choi model suggested GCB subtype showed much better prognosis than ABC subtype (P=0.047), while Hans model shed no statistically significant difference (P=0.285). (3) Ki-67 of 75% was found to significantly discriminate patients with good or bad prognosis. In R-CHOP group at the same time, low Ki-67 (P=0.017) and CD5-negative groups (P=0.012) were better. Cox proportional hazards regression model showed that IPI score (P=0.002) and Ki-67 (P=0.019) were independent adverse prognostic factors.

CONCLUSIONThe Ann Arbor stage, IPI score, extranodal involvement status and Ki-67 were significantly associated with prognosis .Compared to Hans algorithm, Choi had an advantage to predict the different prognosis between subtypes, and ABC group had poor outcome. Finally, both Ki-67 and IPI score were independent adverse prognostic factors.

BACKGROUNDAlthough neurologic manifestations often complicate the course of patients with multiple myeloma, direct central nervous system invasion is rare. This study explored the neurologic symptoms, signs, clinical features, therapy and prognosis of Chinese patients with central nervous system myeloma invasion.

METHODSThe diagnosis, therapy and prognosis were analyzed retrospectively in 11 Chinese multiple myeloma patients with central nervous system infiltration from a total of 625 patients who have been treated at Changzheng Hospital (Shanghai, China) between January 1993 and May 2009. Survival curve was constructed with the use of Kaplan-Meier estimates.

RESULTSThere were 11 patients with central nervous system involvement from 625 multiple myeloma patients. The occurrence rate was 1.8%. Ten of the 11 patients had other extramedullary diseases. Symptoms included cerebral symptoms, cranial nerve palsies, and spinal cord or spinal nerve roots symptoms. Cerebrospinal fluid was abnormal in 7 patients, usually exhibiting pleocytosis and elevated protein content, plus positive cytologic findings. Specific magnetic resonance imaging findings suggestive of central nervous system invasion were found in 9 patients. After a median follow-up of 19 months, 3 patients were alive. The median overall survival for all patients was 23 months, while the median overall survival for patients after central nervous system invasion was merely 6 months.

CONCLUSIONSIt is exceedingly rare for there to be central nervous system infiltration in multiple myeloma patients. When it occurs, the prognosis is extremely poor despite the use of aggressive local and systemic treatment including stem cell transplantation.

Objective To develop a method of quantitative analysis of multi-components by single marker (QAMS) for simultaneously determining five compounds in Curcumae Aromaticae Radix.Methods An HPLC method was developed as QAMS to determine curcuma diol,ocathydro-1,4-dihydroxy-1,4-dimethyl-7-(propan-2-ylidene)azulen-5(1H)-one,original curcumol and curcumin in Curcumae Aromaticae Radix,using curdione as intermal reference substance,and the relative correction factor (RCF) of the four components was determined by HPLC with good reproducibility.Their contents in 10 batches of samples,collected from different areas,were determined by both external standard method and QAMS.Result No significant differences were found in the quantitative results of four compounds in 10 batches of Curcumae Aromaticae Radix determined by external standard method and QAMS.Conclusion It is feasible and suitable to evaluate the quality of Curcumae Aromaticae Radix by QAMS.

OBJECTIVETo evaluate the efficacy of autologous stem cell transplantation (ASCT) in the treatment of multiple myeloma (MM) and its impact on the prognosis of MM.

METHODSRetrospective analysis was performed in 28 patients with MM (group A) treated with ASCT in our hospital from October 1998 to February 2007, compared with those not received ASCT in the same time period including 23 patients with near complete response (nCR) or better (group B) and 25 patients with partial response (PR) (group C). The duration of response (DOR), time to progression (TTP) and overall survival (OS) were compared by Kaplan-Meier method in the 3 groups.

RESULTSEight patients without nCR or better (7 in PR and 1 in MR) after ASCT achieved CR (2 cases) and nCR (5 cases). Complete response (CR) rate was 10.7% (3 cases) and 42.9% (12 cases) before and after ASCT respectively in group A. DOR was 33 months for group A, 17 months for group B and 18 months for group C, and TTP was 45, 43 and 28 months respectively. After a median follow-up of 30 months, patients in group A and in group B had a trenel of longer OS than in group C although there was no statistically significant difference.

CONCLUSIONSASCT can further enhance the response, prolong the DOR and TTP and probably OS, and therefore improve the quality of life in MM. MM patients not achieved good response by non-ASCT therapy may benefit from ASCT.

OBJECTIVETo evaluate the efficacy of allogeneic peripheral blood stem cell transplantation (allo-PBSCT) from sibling donors for treatment of multiple myeloma (MM).

METHODSTen patients with MM received allo-PBSCT with conditioning consisting of fludarabine plus melphalan and cyclophosphamide mostly.CsA plus mycophenolate mofetil (MMF) and short-term MTX were applied to prevent graft versus host disease (GVHD) in 8 patients, FK506 plus short-term MTX in other 2 patients.

RESULTSAll patients engrafted successfully, the median time for ANC > 0.5 × 10(9)/L was 16 (12 - 24) days, and for BPC > 20 × 10(9)/L 23 (16 - 102) days. Five patients developed acute GVHD, and only one III-IV aGVHD. Of 9 patients, 7 developed chronic GVHD. The transplant-related mortality (TRM) at 100 days was 10% (1/10), mainly from heart and renal failure and severe infection. The 1-year expected overall survival (OS), 1-year disease-free survival (DFS) and relapse rate were 67.5%, 55.56% and 11.11% respectively. Up to now, 6 patients were still alive, of them 1 patient have survived over 99 months after allo-PBSCT.

CONCLUSIONYoung MM patients having HLA-identical sibling donors well tolerated allo-PBSCT based on fludarabine to prolong their OS by reducing TRM, though further work is warranted.
