Objective To investigate the role and mechanism of resveratrol in a rat model of complex region-al pain syndrome type Ⅰ(CRPS1). Methods 50 male SD rats were divided into control group(group A),sham operation group(group B),model group 1(group C),model group 2(group D),and model group 3(group E). Groups A,B and C received 5%DMSO;group D received ISO-1 of 1 mg/(kg·d);and group E received resveratrol of 20 mg/(kg · d)for 14 days. Pain behaviors were assessed on days 0,7,and 14. Serum levels of MIF and TNF-αwere detected by ELISA. MIF ,total ERK1/2 and p-ERK1/2 in sciatic nerve were detected by Western blot. Re-sults On days 7 and 14 after treatment,resveratrol injection,similar to ISO-1,significantly improved the pain threshold;serum levels of MIF and TNF-α were significantly decreased;expressions of MIF ,total ERK1/2 and p-ERK1/2 in sciatic nerve were also decreased significantly in group E,which were significantly lower than group C (P < 0.05). Conclusions Resveratrol can significantly improve pain threshold ,decrease expressions of MIF and p-ERK1/2 in a rat model of CRPS1,which might be involved in the inhibition of ERK signaling pathway.

Objective To evaluate the efficacy and toxicities of gemcitabine plus oxaliplatin with R-GemOx or without (GemOx) rituximab regimen in the treatment of relapsed or refractory diffuse large B-cell lymphoma in elderly patients.Methods A total of 39 patients with relapsed or refractory diffuse large B-cell lymphoma received R-GemOx or GemOx chemotherapy.There were 16 patients in R-GemOx and 23 patients in GemOx group.Patients in both groups received gemcitabine 1000 mg/m2,d1,at land 8 day and oxaliplatin 130 mg/m2,d1 at lday.Patients in R-GemOx additionally received rituximab 375 mg/m2.Every 21-28 days was 1 cycle.The toxicities were evaluated after 1 cycle of chemotherapy.The efficacy was evaluated after 2 cycles of chemotherapy.Results In R-GemOx group,the total response rate was 62.5％,and the clinical benefit rate was 87.5％.In GemOx group,the total response rate was 47.8％,and the clinical benefit rate was 73.9％ There was no significant differences between the two groups.There was a significant difference in the median time-to-progression (TTP) between R-GemOx group (6.4 months) and GemOx group (5.0 months) (P ＜ 0.05).The major toxicities were marrow suppression and gastrointestinal reaction,which had no significant differences between the two groups.Conclusions R-GemOx and GemOx regimen are effective and safe for the elderly patients with relapsed or refractory diffuse large B-cell lymphoma(DLBCL).But the patients with relapsed/refractory DLBCL treated with R-GemOx had a longer median time-to-progression than with GemOx regimen.

AIM: To explore the characters of fibroblast-like (F-L) cells cultured from granunocyte clony stimunating factor (G-CSF)-mobilized peripheral blood cell (PBC) harvests. METHODS: The adherent cells in the PBC harvests were cultured for 2 week in the mediums of RPMI-1640/L-DMEM/G-CSF or interleukin-3 (IL-3) plus RPMI-1640, the cultured F-L cells were analyzed by flow cytometry (FC). RESULTS: The adherent non-confluent F-L cells obtained from the four groups were similar in their phenotypes: CD33+, CD11c+, CD64+, CD14+, CD45+, HLA-DR+, CD86+, CD34-, CD38-, CD3-, CD19-, CD56-, CD29-, CD44-, CD105-. The F-L cells are similar to monocytes except CD38-and were distinct from dendritic cells (DC) or mesenchymal stem cells (MSC). CONCLUSION: The cultured F-L cells are macrophages rather than DC or MSC. G-CSF, rhIL-3 enhances their numbers.

Objective To explore the in vitro spermostatic effects and the mechanisms of ceritinib,a novel candidate from the active compound pools previously screened for the regulation of sperm function.Methods The vigor sperm of human and mouse were incubated with ceritinib for 20seconds,and the sperm motility was evaluated by computer assistant sperm analysis (CASA).The integrity of the sperm plasma membrane and the survival ratio of sperm was assessed by hypo-osmotic swelling (HOS) assay and SYBR-14/PI staining.The damage of sperm plasma membrane was detected by electron microscope.The cytotoxicity of ceritinib to VK2/E6E7,End1/E6E7 and Ect1/E6E7 cells was measured by CCK-8 assay and fluorescent staining.Results The minimal effective concentration (MEC) of ceritinib to (5-10) × 106/mL human sperm within 20 seconds was (74.87 ± 31.46)μmol/L,which was significantly lower than the MEC of nonoxynol-9 (219.75 ± 20.89) μmol/L measured in the same condition.The time-dose related spermostatic effects of ceritinib were measured by CASA system.Ceritinib was able to damage sperm membrane and caused sperm death with HOS and SYBR-14/PI staining.With electron microscopy,the sperm membrane was observed to be ruptured,and the heads and tails of sperm were separated by ceritinib.Ceritinib was also able to damage the epithelial cells.Conclusions Ceritinib has acute spermostatic effects and potential contraceptive effects.

Objective To summarize the CT features of pulmonary mucormycosis in post hematopoietic stem cell transplantation (HSCT) patients with leukemia,to provide timely and accurate guidance for clinical treatment.Methods 9 pulmonary mucormycosis in post HSCT patients with leukemia confirmed by surgery,biopsy and sputum culture were analyzed retrospectively.Distribution,morphology and CT features of the disease were analyzed and summarized.All patients were underwent non-enhanced MSCT.Results Reversed halo sign (n=7);patchy ground glass opacity (GGO) (n =5);bilateral multiple pulmonary nodules and nodular GGO (n=3);bilateral multiple pulmonary micro-cysts with spiculate boundary (n=1);pleural effusion (n=2);pneumo-mediastinum (n 1) were seen.Two or more than two CT signs were seen in some patients.The interval time between the appeared reversed halo sign and the transplantation were 0.5-19 months in 7 patients,which median time was 10 months and 6 cases (85.7％) appeared within 18months.8 patients (88.9 ％) presented cough,expectorated white or yellow phlegm,among them,4 cases (50 ％) presented bloodstained sputum or hemoptysis.3 cases (37.5 ％) presented left chest pain.1 case was asymptomatic.6 patients (66.7 ％) presented significant increased body temperature with the range from 38.4 ℃ to 39.6 C,the median was 39 C.3 patients (33.3％) showed normal temperature.The WBC counting was between 0.16-3.31 × 109/L,the median was 0.7 × 109/L.The neutrophil cell counting was between 0-2.46 × 109/L,with the median of 0.09 × 109/L.Among them,7 patients (77.8％) found reversed halo sign with neutrophil counting between 0-1.63 × 109/L,and the median was 0.09 × 109/L.Conclusion Various imaging manifestations of pulmonary mucormycosis are seen in post HSCT patients with leukemia.When patients is in agranulocytosis phase after transplantation HSCT,it is highly suggested pulmonary mucormycosis infection when the characteristic reversed halo sign is found.

Objective To summarize the MRI manifestations of immunosuppressive drugs associated encephalopathy after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in children with aplastic anemia. Methods Fifteen patients with immunosuppressive drugs associated encephalopathy after allogeneic hematopoietic stem cell transplantation for aplastic anemia during January 2014 to October 2016 were analyzed retrospectively. There were 7 males and 8 females, aged from 3 to15 years old, with the median age of 7 years old. Ten cases presented dizziness and headache while other 4 cases presented blurred vision, blind and gaze. Only one case suffered from seizure and loss of consciousness. MRI patterns including distribution, morphology and signal intensity were analyzed after treatment. Follow up MRI were performed after reducing drug dose and symptom remission. The duration of immunosuppressive drugs associated encephalopathy of the 15 cases were 1-14 months, with 6 months in 9 cases. Results Focal lesions were found in 11 cases, in which the deep nuclei were involved in one case and the white matter was involved in 10. Four patients showed both cerebral cortex and white matter lesions, including cerebellum and brainstem invasion in one patient. No corpus callosum lesions were found. Various degree of brain atrophy was found in all patients. Cortical lesions showed swelling and involved subcortical white matter presented as arc shape or strip-like lesions. Patchy patterns were found in deep white matter. Thin layer shaped lesions were found in the periventricular white matter. Small flake-like lesions were found in the brain stem and the cerebellum. The lesions showed hypointensity on T1WI, equal or high signal on T2WI. T2WI FLAIR showed equal or high signal;DWI in the cortex and subcortical white matter lesions showed iso-or high signal, while other lesions were isointense. Eight cases acquired clinical relief in short term without obvious improvement on MRI image. Both clinical symptoms and imaging findings improved in 6 cases. One case showed clinical relief but progression on MRI. Conclusions MRI is an effective way to find immunosuppressive drugs-related encephalopathy in children with aplastic anemia after allogeneic hematopoietic stem cell transplantation. It can help the diagnosis and provide the information for clinical treatment.
