Objective To investigate the efficacy and safety of bortezomib-based induction regimen followed by autologous hematopoietic stem cell transplantation (ASCT) in pationts with multiple myeloma (MM). Methods A retrospective analysis was performed upon clinical data of 62 MM patients who received bortezomib-based induction regimen followed by ASCT from June 2006 to June 2011.All patients were followed up to September 30,2011.Results Overall response rate [ complete remission (CR) + near complete remission (nCR) + partial remission (PR) ],≥ nCR rate (CR/nCR) and CR rate of postinduction with bortezomib-based regimen were 88.7％,66.1％ and 24.2％,respectively.After ASCT,CR rate and CR/nCR rate were increased to 50.0％ and 82.3％,respectively,with significant differences (P =0.003 and P =0.032).The median time of neutrophil and platelet engraftment was 12.0 (9-43) days and 13.5 (0-120) days,respectively. Significances were found in neutrophil and platelet engraftment between MM patients with and without prior exposure to alkylating agents. Furthermore,engraftment of neutrophil and platelet in patients receiving peripheral blood stem cell transplantation were faster than those receiving bone marrow transplantation.No unexpected side effects occurred.The median time of follow-up was 26.5 (7-61) months.The median overall survival (OS) was not reached and the median progression-free survival (PFS) was 30 months.There were significant differences in OS and PFS between patients obtaining CR/nCR and those with ≤ PR before ASCT.Conclusions Bortezomib-based induction regimen can improve the efficacy of ASCT in MM patients.The side effects are tolerant.Higher response quality before ASCT can translate to high rates of OS and PFS following high-dose therapy and stem cell transplantation.

OBJECTIVETo discuss the clinicopathological features and prognostic factors of gastric lymphoma.

METHODS83 gastric lymphoma cases were analyzed retrospectively in accordance to the criteria of the new World Health Organization classification for neoplastic diseases of the hematopoietic and lymphoid tissues. The correlations between clinicopathological features, therapeutic measures and survival were discussed.

RESULTSThe age of patients ranged from 25 to 77, with a median of 52. The number of males were similar to that of females. There were no specific symptoms. The most common symptoms were stomach ache (60 cases, 72%) or discomfort. The duration of symptoms was often long and with a history of chronic gastric diseases (21 cases, 25%). 13 cases had multiple lesions in the gastrointestinal mucosa. 51 cases (61%) were accompanied by lymph node involvement. According to the new World Health Organization classification for neoplastic diseases of the hematopoietic and lymphoid tissues, 57 cases were extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT)-type (MALT lymphoma), 23 were diffuse large B cell lymphoma accompanying MALT lymphoma, 2 were diffuse large B cell lymphoma and 1 was follicular lymphoma. Of all the cases, 31 were stage I E, 38 stage II E, 8 stage III E and 6 stage IV by the Ann Arbor staging system (1972). The total 5-year and 10-year survival rates were 77.8% and 70.1% respectively, with the mean survival time of 146 months. The 5-year and 10-year survival rates of MALT lymphoma were 77.4% and 72.3%, the 5-year and 10-year survival rates of diffuse large B cell lymphoma accompanying MALT lymphoma were 81.8% and 68.2%, the 5-year survival rate of diffuse large B cell lymphoma was 50.0%.

CONCLUSIONSThere are no specific symptoms in gastric lymphoma patients. Extranodal marginal zone lymphoma of MALT-type is the main histopathological type of gastric lymphoma, often accompanied by multiple mucosa involvement and also often accompanied by a history of chronic gastric disease. The lesion is usually localized for a long time, with a very good prognosis. Survival rate has a significant correlation with lymph node involvement and clinical stage. No correlations were found between the survival rates with age, gender, B symptoms, invasive depth of the wall of stomach, the size and range of the tumors or different therapeutic measures.

OBJECTIVETo observe effects of acupuncture combined speech therapy for cerebral palsy children with linguistic retardation.

METHODSTotally 132 cerebral palsy children were randomly assigned to the speech training group (Group A, 44 cases) and the routine acupuncture combined speech training group (Group B, 44 cases), and the acupuncture combined speech training group (Group C, 44 cases). Patients in Group A received one to one training including game therapy, therapy of communication attitudes, and so on. Those in the other two groups were needed at Baihui (GV20), Sishencong (EX-HN1), the first language zone, the second language zone, and the third language zone. Those in Group B were treated with electric needling and then speech training. Those in Group C were treated with language training, while needling with needle maintaining for 40 min. All patients were treated once daily, 5 times per week, 20 times as one course of treatment, 6 courses in total. The efficacy was assessed using S-S phonetic speech developmental retardation examination (CRRC version). The development quotient (DQ) was observed referring to the Gesell intellectual development scale before treatment, after 3 and 6 treatment courses.

RESULTSCompared with Group A (the total effective rate: 51.3%, DQ value: 58.1 +/- 13.3), better effects were obtained in Group B (the total effective rate: 77.5%, DQ value: 60.4 +/- 13.5) and Group C (the total effective rate: 81.0%, DQ value: 64.0 +/- 11.6) (all P < 0.05). There was no statistical difference in the total effective rate or post-treatment DQ value between Group B and Group C (P > 0.05).

CONCLUSIONAcupuncture combined speech therapy showed obvious effects on cerebral palsy children with linguistic retardation.

OBJECTIVETo investigate the role of transient receptor potential melastatin 8 (TRPM8) channels in migraine mechanism in rats by measuring the changes in expression of TRPM8 in the trigeminal nerve of rats with migraine.

METHODSTwenty male Sprague-Dawley rats were randomly and equally divided into a blank control group and a model group. Nitroglycerin (10 mg/kg) was injected subcutaneously in the back of the neck once a week for 5 weeks, to prepared a rat model of migraine without aura. Normal saline was injected subcutaneously instead of nitroglycerin in the control group. At 4 hours after the final injection, behavior scoring of all rats was performed, and then the trigeminal nerve ganglions of rats in both groups were collected for measurement of expression of N-methyl-D-aspartate receptor (NMDAR), protein kinase A (PKA), and TRPM8 using immunohistochemical staining, immunofluorescence, and Western blot, respectively.

RESULTSThe behavior score in each week during the rat model preparing was significantly higher in the model group than in the control group (P<0.05). The expression of NMDAR, PKA, and TRPM8 in the model group was significantly higher than in the control group (P<0.01). Both the behavior score and the expression of NMDAR were positively correlated with the expression of TRPM8 (r=0.822 and 0.794 respectively; P<0.01).

CONCLUSIONSTRPM8 may be involved in migraine mechanism probably by activation of the NMDAR pathway.
