High-dose melphalan (Mel) is considered as a current standard preparative regimen in autologous stem cell transplantation (ASCT) for multiple myeloma (MM). Irradiation in total body (TBI) combined with Mel is not superior to Mel alone, and the adverse reactions are increased at the same time. The efficacy of 200 mg/m2 Mel is much better than that of 100-140 mg/m2 Mel in young patients. Several regimens including MelBU, TBC, BCV, MET, MTC, MelBCNU, VMel, MTC as well as bendamustine have similar treatment outcomes compared with 200 mg/m2 Mel. Other strategies need to be evaluated in different trials.

Objective To observe the effect of levocamitine on cardiac function of patients with dilated cardiomyopathy (DCM).Methods 40 patients with DCM were randomly divided into control group (n =20) and the experimental group(20 cases).Control group was given conventional drug such as digitalis,furosemide,benazepril hydrochloride,antisterone for treatment,the experimental group was given levocarnitine on the basis of control group.The treatment efficacy and the situation of cardiac function were compared between the two groups.Results The total effective rate was 95.0％ and 80.0％ in the experimental group and the control group,respectively,the difference was statistically significant(x2 =10.286,P ＜ 0.01).Compared with the control group,the parameters of stroke volume,cardiac output,ejection fraction,and left ventricular fractional shortening rate were significantly increased in the experimental group after treatment(all P ＜ 0.05).Conclusion Levocarnitine can improve cardiac function based on the conventional treatment.

Objective To investigate the operative outcomes of anatomic and functional reconstruction of the spinal posterior column after resection of intraspinal neoplasms.Methods From January 2010 through October 2014,we treated 32 patients with intraspinal neoplasm in the spine.They were 18 men and 14 women,13 to 62 years of age (average,38 years).The neoplasm was detected in the cervical spine in 10 cases,in the thoracic spine in 14 and in the lumbar spine in 8.All cases received expansive open door laminoplasty via the posterior approach for resection of the intraspinal neoplasm,followed by replantation and titanium plate fixation for anatomic and functional reconstruction of the spinal posterior column.The neural functional recovery,spinal motion and sagittal diameter of the spinal canal before and after operation,spinal stability and graft fusion were observed.Results The patients were followed up for 3 to 23 months (average,13 months).All the intraspinal neoplasms were completely resected.The Frankel grading of neural functional recovery was improved differently in all the cases.By the final follow-ups,the spinal motion was normal in all the cases,without any significant limitation.Graft fusion and rigid internal fixation were achieved in all the cases.Short-term follow-ups revealed no signs of spondylolisthesis or spinal instability.At the final follow-ups,the 3-D CT reconstruction showed no significant shortening in the sagittal diameter of the same spinal canal before and after operation (P ＞0.05).Conclusions For intraspinal neoplasm in the spine,the whole vertebral lamina is opened or removed via the posterior approach to resect the neoplasm,followed by reduction of the vertebral lamina and mini titanium plate fixation to reconstruct the anatomy and function of the original spine.This is an ideal way to treat intraspinal neoplasms in the spine.

Objective To investigate the prognostic significance of preoperative fibrinogen levels and explore a new prognostic predictor for colon cancer patients. Methods From January 2007 to Decem-ber 2008,the clinical data of colon cancer patients with radical were reviewed retrospectively. Patients were divided into different groups according to BMI,tumor size,stage,differentiation degree,gross type,vascular infiltration,CEA and mGPS score. Differences in preoperative fibrinogen concentration and overall survival were compared between groups. Results A total of 255 patients were enrolled in this study,the mean pre-operative fibrinogen concentration of enrolled patients was(3. 17 ± 0. 88)g/ L. There were significant differ-ences in And preoperative fibrinogen concentration among patients with different tumor size,stage,differen-tiation degree,gross type,vascular infiltration,CEA and mGPS(P < 0. 05). Moreover,result of univariate analysis manifested that the level of preoperative fibrinogen concentration was associated with the overall survival rate. Conclusion Preoperative fibrinogen concentration is associated with the clinicopathologic features of patients with colon cancer,which can serve as a new prognostic marker for prognosis evaluation.

Objective To investigate and compare the diagnostic value of fine needle aspiration biopsy(FNAB) and core needle biopsy(CNB) in the treatment of patients with invasive breast cancer.Methods Given 100 cases of patients with newly diagnosed breast cancer biopsy in our hospital from November 2015 to November 2016,50 cases of patients with FNAB into the observation group,50 cases of patients with CNB into the control group.Taken the pathologic results as a diagnostic gold standard and compared the diagnostic value of two diagnostic methods in invasive breast cancer.Detected the human epidermal growth factor receptor 2(Her-2),estrogen receptor(ER) and progesterone receptor(PR) preoperatively and compared the adverse reactions of puncture of patients in two groups.Results 30 cases of patients in the observation group showed axillary lymph node metastasis and 20 cases of patients had no axillary lymph node metastasis,21 cases of patients were positive cases of axillary lymph node metastasis accepted FNAB examination,the sensibility was 70.00％.29 cases of patients in the control group showed axillary lymph node metastasis while 21 cases of patients didn′t have axillary lymph node metastasis,23 cases of patients were positive cases of axillary lymph node metastasis accepted FNAB examination,the sensibility was 74.19％.Compared the ER、PR、Her-2 antibody with the testing result of primary tumor after operation.The diagnostic accordance rates in the observation group were 93.55％,91.67％,92.86％ respectively.The diagnostic accordance rates in the control group were 94.12％,92.31％,86.67％,the differences in two groups were not statistical significance(P>0.05).The adverse reaction rate was 4.00％ in the observation group and 0.00％ in the control group after puncture.Conclusion The diagnostic sensibility of FNAB is poorer than CNB in the diagnostic procedure of invasive breast cancer.ER,PR,Her-2 in two diagnostic methods keep a high consistency with the testing result of primary tumor after operation.

To improve flexibility and reliability of iris recognition algorithm while keeping iris recognition success rate, an iris recognition approach for combining SVM with ICA feature extraction model is presented. SVM is a kind of classifier which has demonstrated high generalization capabilities in the object recognition problem. And ICA is a feature extraction technique which can be considered a generalization of principal component analysis. In this paper, ICA is used to generate a set of subsequences of feature vectors for iris feature extraction. Then each subsequence is classified using support vector machine sequence kernels. Experiments are made on CASIA iris database, the result indicates combination of SVM and ICA can improve iris recognition flexibility and reliability while keeping recognition success rate.

Serum prostate-specific antigen (PSA) is composed of the PSA precursor protein (proPSA) in the absence of the leader peptide induced by human kallikrein 2 (hK2). There are many forms of PSA in the blood, including free PSA and bound PSA. Serum proPSA, as a free PSA, has many isoforms, among which, [-2]proPSA (p2PSA) cannot be activated by hK2 and therefore exists stably in the blood. Serum p2PSA is a homologous isomer of PSA. Serum prostate health index and % p2PSA, as the derivative indexes of p2PSA and molecular markers associated with the development and progression of prostate cancer, can reduce serum PSA test-induced excessive diagnosis and treatment of the malignancy and improve the accuracy of its prediction. This review summarizes recent progress in the studies of serum p2PSA and its derivative indexes in prostate cancer.
