Objective To assess the impact of antithymocyte globulin (ATG) on the incidence of graft-vs-host disease (GVHD) in hematopoietic stem cell transplantation from unrelated donors.Methods A total of 92 patients with hematological malignancies including leukemia,myelodysplastic syndrome (MDS) and lymphoma who underwent hematopoietic stem cell transplantation from unrelated donors from January 1999 to December 2011 were included in this retrospective analysis.Patients were classified into ATG group (n =66)and non-ATG group (n =26) according to the GVHD prophylaxis regimen.The incidence of acute GVHD (aGVHD) and chronic GVHD (cGVHD),risk factors of aGVHD and cGVHD and impact of ATG on the overall survival (OS),treatment related mortality (TRM) and relapse rate were analyzed.Results Grade Ⅱ-Ⅳ aGVHD (26.7 ％ vs 44.0 ％,P=0.12) or grade Ⅲ-Ⅳ aGVHD (13.3 ％ vs 8.0 ％,P =0.74) were not significantly different between ATG and non-ATG group.However,the incidence of cGVHD in the ATG group was significantly lower (34.0 ％ vs 72.2 ％,P =0.005) than non-ATG group.The incidence of extensive cGVHD was also significantly reduced (10.0 ％ vs 44.4 ％,P =0.005) compared to non-ATG group.In multivariate analysis,the use of ATG prophylaxis significantly decreased the cGVHD (RR =0.22,95 ％CI 0.081-0.599,P =0.003) while one allele mismatch of human leukocyte antigen (HLA) was associated with increased risk of cGVHD (RR =3.25,95 ％ CI 1.39-7.61,P =0.007).As to the extensive cGVHD,the use of ATG was the only independent factor (RR =0.05,95 ％ CI 0.009-0.240,P ＜ 0.001).With a median follow-up of 12 months (1-84 months),ATG prophylaxis had no impact on OS rate (60.4 ％ vs 43.1％,P =0.41),TRM rate (19.8 ％ vs 34.3 ％,P =0.43) and relapse rate (40.6 ％ vs 33.6 ％,P=0.54).Conclusion In hematopoietic stem cell transplantation from unrelated donors,ATG prophylaxis total dose of 6 mg/kg may significantly decrease the incidence of cGVHD and extensive cGVHD without increase of TRMand relapse rate and impairment of OS.

A questionnaire survey on learning motivation of standardized training and influence factors was carried out and 94 residents of general practice responded. The results indicated that over 80% respondents showed a positive attitude to study and hoped to obtain opportunity for continuing education;76% thought the training program was basically rational but still need to be improved; 94% felt that the training model should be adapted to the real conditions and work requirements of Chinese community health centers. The authors suggest some measures to improve the training including suitable textbooks, more rational training programs and further improvement of education system.

Objective To compare the effects of continuous versus intermittent feedings on the growth of very low birth weight infants. Methods Databases of Pubmed,Embase,Ovid,the Cochrane library and CBM were searched through internet,and citations of relevant original studies were also searched manually by using keywords of 'ontinuous,intermittent,nasogastric,premature,very low birth weight' Meta analysis was done on the results of these studies. Results Seven eligible studies with 434 infants were identified,among them,217 were fed using continuous nasogastric gavage,and other 217 were fed by intermittent nasogastric gavage. The result of the Meta analysis revealed that there was no statistical difference in the growth of the infants between two feeding methods. Conclusions Feeding methods are associated with similar outcomes when calorie intake is guaranteed.

Objective A retrospective analysis of patients with T-cell lymphoma (TCL) received autologous peripheral blood stem cell transplantation (APBSCT) was performed to evaluate the outcome of APBSCT.Methods A total of 22 patients who underwent APBSCT from September 2006 to December 2011 in Ruijin hospital were enrolled in the study,including 6 cases of lymphoblastic lymphoma and 16 of peripheral T-cell lymphoma (8 anaplastic large cell lymphoma, 4 PTCL-u, 1 subcutaneous panniculitis-like T-cell lymphoma, 2 nasal type extranodal NK/T and 1 primary cutaneous T-cell lymphoma). All patients were diagnosed based on the WHO Classification of Tumors of Hematopoietic and Lymphoid Tissues. Conditioning regimens were high-dose chemotherapies alone which include 13 cases with BEAM, 4 with ICE and 5 with CBV. The outcomes of the treatment were evaluated according to the revised International Working Group criteria.Results With a median follow-up of 13.1(1-60) months,the predicted 2-year overall survival (OS) and progression-free survival (PFS) after transplantation were (67.6±11.0) ％ and (71.1±11.1) ％,respectively.A total of 6 patients experienced disease progression and 5 patients eventually died of disease. When all these patients based on the remission status before APBSCT (CR1 vs non-CR1) and chemosensitivity (sensitive vs refractory) were further classified, the PFS rates and OS rates were 100 ％ and 91.7 ％ respectively in CR1 or chemosensitive patients which were significantly higher than patients not in CR1 (42.6 ％ ) or with chemoresistant disease (19.0 ％ ). Conclusion Remission status and chemosensitivity at the time of transplantation significantly affect the outcome of APBSCT for TCL patients, thus it can be recommend to perform APBSCT for patients either in CR1 or early stage when the disease remain sensitive to chemotherapy.

Objective To study the alterations in neurobehavior of rats with diffuse axonal injury(DAI) and to evaluate the potential role of basic fibroblast growth factor(bFGF). Methods A weight-drop device was employed to build the DAI model.An injection of bFGF subdurally and subcortically was given to the bFGF therapeutic group(n=60).Besides,normal control(n=20) and injured control group(n=60) were established.The elevated walkway test,prehensile traction test,sensorimotor integration test and the Morris' water maze test were adopted to examine the motor and memory abilities.After the implantation of skull electrodes,P3-like potential was explored in rats before and after injury. Results After DAI,the scales of the elevated walkway test,prehensile traction test,sensorimotor integration test and the Morris' water maze test were decreased,and the rats in the bFGF therapeutic group presented a better behaviour in the early stage.The latency of P3-like potential prolonged significantly in rats with DAI,with the P3-like potential in the injured control group longer than that in the bFGF therapeutic group(P

Objective To study the alterations in pathology and immunohistochemistry in rats with diffuse axonal injury(DAI) and the effects from basic fibroblast growth factor(bFGF). Methods A weight-drop device was employed to produce DAI in rats.In the treatment group(n=60),bFGF was injected subdurally and subcortically.Besides,normal control group(n=20) and injury-control group(n=60) were also established.The pathological changes were observed by light microscopy and electromicroscopy,and the expression of brain-derived neurotrophic factor(BDNF),growth associated protein-43(GAP-43) and glial fibrillary acidic protein(GFAP) were also examined by immunohistochemistry. Results Typical pathological changes were observed in the basal portion of pons,corpus callosum and white matter of cerebral hemisphere in the rats with DAI.And an upregulation of GFAP,GAP-43 and BDNF was also found.In the treatment group,better outcomes of pathological changes were observed.bFGF increased the expression of BDNF and GAP-43,while inhibited the immunoreactivity of GFAP. Conclusion Topical application of bFGF can improve brain tissue regeneration and speed function recovery in rats with DAI,though its long-term effect warrants further study.

Objective : To evaluate the effect of low dose naloxone on remote seizure susceptibility after repeated febrile seizures(FS) in developing age. Methods: Warm water induced rat FS model was developed in this study.Forty nine SD rats were randomly divided into two groups: normal control group( n =10) and hyperthermic seizure group( n =39).The latter was further divided into FS control group( n =13) and naloxone treated group( n =26). The dose of naloxone was different in the two naloxone treated groups(13/each group). One group dose was 1 mg/kg, and the other 2 mg/kg. Each rat of hyperthermic seizure groups was induced to have 7 febrile seizures at the interval of 1 day. The rats were weighed and injected intraperitoneally with naloxone once the FS occurred in naloxone treated group, while the rats of other groups were injected with 0.9% sodium chloride. After the seventh stimulation, all rats were left un stimulated for 2 months, then re stimulated. Re stimulated seizureincidence rate, seizure duration and seizure grade in different groups were observed and compared with each other. Hippocampal mossy fiber sprouting was detected by Timm stain. Results: In naloxone treated group, the rats'seizure duration and seizure grade [(5.66?2.78) min,(2.97? 1.18)] significantly decreased ( t =5.035, P
