Objective To assess the efficacy of high dose dexamethasone combined with bortezomib and thalidomide in multiple myeloma (MM) patients with acute renal failure.Methods 23 newly diagoosed MM patients with acute renal failure were treated with high dose dexamethasone combined with bortezomib and thalidomide.Results Reversal of renal failure was documented in 58.3 ％ (7/12) of those severe renal failure patients and 81.8 ％ (9/11) of renal failure patients.Renal function was reversed in 69.5 ％ (16/23) of all patients.The total response rate for MM was 60.9 ％ (14/23).The median time to response was 2 (1-5) months. Overall survival (OS) at 3 years was 56.5 ％ and the median survival time was 34.4 months.Conclusion Renal failure was reversible in the majority of newly diagnosed MM patients treated with highdose dexamethasone containing regimens.The addition of novel agents thalidomide and (or) bortezomib is safe and induces a more rapid renal failure reversal compared with routine chemotherapy.

Objective To compare the efficacy and toxicity of thalidomide-COMP (T-COMP) and thalidomide-VAD (T-VAD) regimens in previously untreated multiple myeloma (MM) patients.Methods Forty-nine newly diagnosed MM patients were randomly allocated to either A group (thalidomide-MP/-COMP,19 cases) or B group (thalidomide-VAD,30 cases).All patients received thalidomide 200 mg p.o.daily.Patients in group A received additionally vincristine 0.4 mg i.v.on day 1-4,cyclophosphamide 200 mg i.v.on day 1-4,melphalan 4 mg tid p.o.on days 1-5,prednisone 60 mg p.o.daily on days 1-5.Patients in group B received additionally vincristine 0.4 mg i.v.on day 1-4 and epirubicin 10 mg/m2 i.v.,on day 1-4 and dexamethasone 40 mg p.o.daily on days 1-4,9-12 and 17-20 for the first cycle and on days 1-4 for the next three cycles.Treatment was administered every 28 days.The therapeutic response was evaluated based on the International Myeloma Working Group Criteria (IMWG 2006) after the treatment.The toxicity was graded according to NCI common terminology criteria for adverse events v 3.0.Results On an intention-to-treat basis,at least partial therapeutic response was observed.The rates were 73.7 ％ and 53.3 ％ in group A and B respectively (x2 =2.029,P =0.154).Overall survival (OS) rate at 2 years were 52.6 ％ (10/19) in group A and 53.3 ％ (16/30) in group B,respectively (x2 =2.468,P =0.116).Considering overall toxicity,constipation,peripheral neuropathy,dizziness/somnolence,skin rash and edema were significantly higher in group B compared with group A,but the incidence of toxicities grade 3-4 was low and similar in both arms.Conclusion The overall response rate of T-MP/T-COMP regimen is similar with that of T-VAD regimen,suggesting this regimen cannot be chosen as the first treatment for patients with non-implantation therapy.

BackgroundThe progressive death of retinal ganglion cells (RGCs) is the primary pathological characteristics of visual defects in glaucomatous eye.Research showed that endoplasmic reticulum stress (ERS) is involved in this progression.Glucose-regulated protein 78 ( GRP78 ) is a special marker of ERS.To understand the change in expression of GRP78 in the retina under the pressure induced is very important for the protection of visual function.Objective The present study was to observe the expression of GRP78 in rat retina with acute high intraocular pressure (IOP) and investigate the possible effect of ERS in acute glaucoma damage. MethodsFiftysix Wistar rats were randomly assigned to normal control group,anterior chamber punctured group and 12 hours,1 day,3,7,14 days groups following acute IOP rising.The acute high IOP models were established in the right eyes of 4.0 Wistar rats by paracentesis of the anterior chamber and infusion of normal saline solution into the anterior chamber.The histopathology changes of the retina were examined by hemotoxylin and eosin staining.The expression of GRP78 protein and mRNA in the retina were detected by immunohistochemistry and real-time fluorescence quantitative PCR.ResultsThe retinal layers and cells were clear with normal alignement in the rats of the normal control group and the anterior chamber punctured group.The edema and thickening of retinas appeared in 12 hours after molding and peaked in 1 day after molding.Then the retina decreased in thickness and atrophied from 3 days through 14 days.The expression levels of GRP78 protein (A value) were 0.195±0.006 in the nounal rats and gradually increased from 12 hours through 3 days (0.268±0.017) following molding with the peak value at 1 day (0.499±0.039 ),showing significant differences in comparison with the normal control group (t =0.098,0.304,0.073,P＜0.05),and the reduction in expression at 7 and 14 days were not significantly different from the normal control group ( t =0.002,0.001,P＞0.05 ).The relative value of GRP78 mRNA ( 2△△C1 ) in the retina was 1.011 ±0.013 in the normal control group and gradually up-regulated from 12 hours through 3 days with the peak value at Iday (2.141±0.171 ) and then down-regulated from the third day onwards.A significant difference was seen in 2-△△C1value between the normal control group and 12 hours group,1 day group or 3 group ( t =0.525,1.130,0.409,P＜0.05 ).However,the 2-△△C1 values of GRP78 mRNA at 7 and 14 days was similar to that of the normal control group (t=0.020,0.004,P＞0.05).ConclusionsGRP78 participates in the process of RGCs damage following acute high IOP.The results suggest that interfering with ERS may be helpful for protecting the retina and optical nerve from pressure-induced damage.

Objective:To study the effect and influence factor analysis of DLBCL patient with early stage who receive radiotherapy after chemotherapy.Methods: 374 cases of patients with DLBCL was selected from January 2010 to December 2015 in our hospital. By random number table method, the patients were divided into CHOP group (n=104), R-CHOP+RT group (n=93), R-CHOP group (n=80), CHOP+RT group (n=97). CHOP chemotherapy was given to all patients, 180 patients received radiotherapy after chemotherapy, and 169 patients received rituximab. Survival rates were compared between the 4 groups.Results: The survival rate of R-CHOP group in 12 months, 24 months, 50 months and 100 months were lower than R-CHOP+RT group, but the difference was not statistically significant in twelfth months(x2=2.02,P>0.05). The differences of 24 months, 50 months and 100 months were statistically significant (x2=4.08,x2=4.03,x2=8.79;P<0.05); The survival rate of CHOP group was 12 months and 24 months was higher than CHOP+RT group which the difference was not statistically significant (x2=1.05,x2=0.22;P>0.05); The survival rate of CHOP group in 50 months and 100th months was lower than CHOP+RT, but the difference was no significant difference (x2=1.62,x2=0.03;P>0.05). Smoking index, whether the use of rituximab, the age associated with the survival of patients, the difference was statistically significant.Conclusion: Early DLBCL patients with R-CHOP and radiotherapy combined treatment can be effective in patients with survival, while the use of rituximab chemotherapy, in addition to smoking on the prognosis of patients with serious adverse effects.
