ABSTRACT
Objective:To investigate the clinical features of IgD multiple myeloma (MM) and the effect and prognosis of daratumumab-based combination therapy.Methods:The clinicopathological data of a IgD MM patient with disease progression and extramedullary infiltration treated with daratumumab in the Affiliated Hospital of Qingdao University in December 2019 were retrospectively analyzed.Results:The 74-year-old woman was diagnosed as IgD MM by bone marrow aspiration and immunofixation electrophoresis. The patient was given VD (bortezomib, dexamethasone), RD (lenalidomide, dexamethasone) and ID (ixazomib, dexamethasone) regimens. In June 2020, the patient developed multiple subcutaneous nodules, and she was assessed as progressive disease with extensive extramedullary infiltration. After treated with daratumumab-PAD (liposomal doxorubicin, bortezomib, dexamethasone) regimen, the patient's subcutaneous nodules were significantly reduced and partially disappeared, and the general condition was significantly improved. But the patient was in a cachexia state and finally died of the irregular treatment and disease progression.Conclusions:IgD MM has a low incidence and a short survival period, and there is no uniform standard treatment. The early application of daratumumab combined with proteasome inhibitors, immunomodulators, cytotoxic drugs and hematopoietic stem cell transplantation may improve the overall survival of patients.
ABSTRACT
Objective@#To investigate the effect of immunophenotyping on prognosis of multiple myeloma (MM) patients treated with bortezomib regimen as main treatment.@*Methods@#Seventy-six MM patients in the Department of Hematology in the Affiliated Hospital of Qingdao University from January 2012 to January 2017 were retrospectively analyzed. The effects of the expressions of CD45, CD56 and other factors on progression free survival (PFS) and overall survival (OS) in MM patients treated with bortezomib-containing regimen were also analyzed.@*Results@#Univariate analysis showed that statistical differences of the median PFS (12 months vs. 19 months, P < 0.001) and median OS (19 months vs. 23 months, P= 0.001) were significant in the group of CD45 positive and negative of MM patients; the median PFS (14 months vs. 21 months, P= 0.014) and median OS (16 months vs. 25 months, P= 0.026) for MM patients with hemoglobin (Hb) < 100 g/L and Hb ≥ 100 g/L were statistically significant; the median PFS (13 months vs. 18 months, P= 0.004) and median OS (14 months vs. 24 months, P= 0.008) for MM patients with albumin (ALB) < 35 g/L and ALB ≥ 35 g/L were statistically significant. The median PFS time and the median OS time in female MM patients were shorter than those in male MM patients (13 months vs. 19 months, P= 0.008; 16 months vs. 25 months, P= 0.008). Multivariate analysis showed that female and CD45 positive were the independent poor prognostic factors for PFS and OS in MM patients (P < 0.05).@*Conclusion@#CD45 positive and female are important prognostic factors for MM patients treated with bortezomib regimen as main treatment.
ABSTRACT
Objective To investigate prognostic factors in patients with primary central nervous system diffuse large B-cell lymphoma (PCNS-DLCBL).Methods The clinical data of 71 patients with PCNS-DLCBL confirmed by pathology and clinical tests, who were admitted to our hospital from 1991 to 2015, were retrospectively analyzed.All patients received chemotherapy, mainly with high-dose methotrexate (HD-MTX, 66/71), and 59 patients received radiotherapy, mainly with whole brain radiotherapy (WBRT)±local boost.The Kaplan-Meier method was used to calculate survival rates, the log-rank test was used for survival comparison and univariate prognostic analysis, and the Cox model was used for multivariate prognostic analysis.Results Fifty-eight patients achieved a complete response (CR), ten achieved a partial response (PR), and three had progressive disease (PD).The 5-year overall survival (OS) rate was 43%, and the 5-year progression-free survival (PFS) rate was 34%.The univariate analysis showed that the factors associated with OS included the following:age of onset, Karnofsky Performance Scale (KPS) score, single or multiple lesions, whether to receive radiotherapy, evaluation results after radiotherapy and chemotherapy, and the presence or absence of recurrence (P=0.000-0.047);the multivariate analysis showed that the three factors that affected OS were age of onset, KPS score, and the presence or absence of recurrence (P=0.000-0.022).The univariate analysis revealed that chemotherapy regimen, whether to receive radiotherapy, total radiotherapy dose, WBRT dose, evaluation results after radiotherapy and chemotherapy, and the presence or absence of recurrence were the factors associated with PFS (P=0.000-0.028);the multivariate analysis revealed that KPS score and the presence or absence of recurrence were associated with PFS (P=0.000-0.011).Conclusions Among patients with PCNS-DLCBL, younger age, higher KPS score, and no recurrence are associated with better OS, and single lesion, radiotherapy, and better evaluation results after radiotherapy and chemotherapy may be associated with better OS;higher KPS score, better evaluation results after radiotherapy and chemotherapy, and no recurrence are the factors associated with better PFS, and HD-MTX chemotherapy, radiotherapy, higher total radiotherapy dose, and higher WBRT dose may be associated with better PFS.Whether to receive radiotherapy after achieving a CR with chemotherapy and the target area and dose of radiotherapy need to be further studied.
ABSTRACT
Objective To evaluate the efficacy of combined red and blue light therapy with acne film coating in treatment of moderate and severe acne.Methods Totally 547 patients with moderate or severe acne were enrolled in the study from March 2012 to July 2014.Using open control,according to the cycle of time sequence will patients were divided into three groups:183 patients (study group) were received alternatively red and blue light therapy twice a week,and acre film coating was applied once a day;182 patients in control group 1 received film coating alone and another 182 patients (control group 2) received light therapy alone.The treatment lasted for 6 weeks in all three groups.The numbers of skin lesions were recorded before and 2,4,6 w after treatment,and the curative effect was evaluated 10 w after treatment.Results The number of skin lesion were significantly reduced 6w after treatment in all three groups,that for study group was most markedly.For patients with moderate acne,the total effective rates in study group and in control groups 1 and 2 were 84.6％ (110/130),58.5％ (76/130) and 51.9％ (67/129),respectively (x2 =21.836,and 31.955,P ＜0.01).For patients with severe acne the total effective rates in study group and in control groups 1 and 2 were 84.9％ (45/53),57.7％ (30/52) and 56.6％ (30/53),respectively (x2 =9.525 and 10.258,P ＜0.01).There are 20 cases in observation group therapy for different degree of erythema,itching,burning,tingling,incidence of side effects was 10.9％ (20/183),control group 1 and 2 were 7.1％ (14/182),12.1％ (22/182),are tolerated.Conclusion The combination of red/blue light therapy with acne film coating is more effective than the application of single method alone for patients with moderate or severe acne.
ABSTRACT
Objective To observe the effect of rosuvastatin calcium on lipid,vascular endothelial growth factor (VEGF),nitric oxide (NO),tumor necrosis factor (TNF)-α and interleukin (IL)-1 in hyperlipidemia patients.Methods One hundred and twenty-seven hyperlipidemia patients were randomly divided into two groups.Patients in the study group included 72 patients which were given rosuvastatin calcium 10 mg and enteric-coated aspirin 100 mg,orally,once a day for 8 weeks.The control group included 55 patients which were only given enteric-coated aspirin 100 mg,orally,once a day for 8 weeks.The change of lipid,VEGF,NO,TNF-α and IL-1 was observed before and after treatment.Results Before treatment,the level of total cholesterol(TC),triglyceride (TG),low density lipoprotein-cholesterol (LDL-C),high density lipoprotein-cholesterol (HDL-C),VEGF,NO,TNF-α and IL-1 in two groups had no significant difference (P ＞ 0.05).After treatment,the level of TC,TG,LDL-C,TNF-α and IL-1 in study group were significantly lower than those in control group [(4.410 ± 0.688) mmol/L vs.(6.491 ± 0.744) mmol/L,(1.762 ± 0.834) mmol/L vs.(2.632 ± 0.792) mmol/L,(2.256 ± 0.347) mmol/L vs.(4.544 ± 0.493) mmol/L,(41.14 ± 5.41) ng/L vs.(71.34 ± 6.76) ng/L,(0.22 ± 0.18) μ g/L vs.(0.42 ± 0.23) μ g/L] (P ＜ 0.05).The level of HDL-C,VEGF and NO in study group were significantly higer than those in control group [(1.807 ± 0.730) mmol/L vs.(1.432 ± 0.514) mmol/L,(564.86 ± 120.02) ng/L vs.(451.23 ± 100.72) ng/L,(42.39 ± 6.71) μ mol/L vs.(33.65 ± 6.24) μ mol/L](P＜ 0.05).No adverse reaction occurred in two groups.Conclusions Rosuvastatin calcium can obviously decrease the level of lipid,elevate the expression of VEGF and NO,and reduce the expression of TNF-α and IL-1.Rosuvastatin calcium can improve vascular endothelial function obviously in hyperlipidemia patients.

ABSTRACT
Objective To investigate the factors affecting the protective effects of morphine preconditioning on murine hippocampal neurons against anoxia/reoxygenation (A/R) injury and the underlying mechanisms.Methods Hippocampal slices (400 μm thick) were prepared using hippocampi isolated from decapitated mice. A/R injury was simulated in vitro using artificial cerebral spinal fluid (ACSF) deprived of O_2 and glucose for 20 min followed by reoxygenation and glucose supply for 2 h. The experiment was performed in 4 parts: I .The slices were incubated with 5 different concentrations of morphine (0.1, 0.3, 0.5, 1.0, 3.0, 10.0 /μmol/L) for 30 min at 30 min before A/R; Ⅱ. The slices were incubated with morphine 3.0 /μmol/L for 5 different periods of time (5, 15, 30, 45, 60 min) at 30 min before A/R; Ⅲ. The slices were incubated with morphine 3.0 μmol/L for 30 min followed by A/R at 6 different intervals (0, 5, 15,30,60, 120 min); Ⅳ. The slices were incubated with (a) chelerythrine (a non-selective PKC antagonist) 10 /μmol/L or (b) εVl-2 (a selective nPKCe isoform antagonist) 2 μmol/L or (c) AIP 2 μmol/L (a selective CaMK Ⅱ antagonist) or (d) MK-801 10 μmol/L (a non-competitive NMDA receptor blocker) for 30 min and then for another 30 min together with morphine 3.0 μmol/L before A/R at 30 min interval. The survival rates of the hippocampal neurons were assessed by TTC staining. Results Neuronal survival rates were significantly higher in morphine preconditioning groups which preconditioned with morphine (0.5-10.0 μmol/L) for 15-60 min at an interval of 0-60 min before A/R than in A/R group. Increase in neuronal survival rate induced by morphine preconditioning was partially blocked by chelerythrine or εV1-2 or AIP or MK-801. Conclusion Preconditioning with appropriate concentrations of morphine (0.5-10.0 μmol/L) for appropriate period of time (15-60 min) at appropriate interval (within 60 min) before A/R can protect hippocampal neurons against A/R injury through activation of nPKCε, NMDA receptor and CaMKⅡ.
