Abstract
Objective: To compare the predictive efficacy of the two thrombosis risk assessment scores (Padua and IMPEDE scores) in venous thromboembolism (VTE) within 6 months in patients with newly diagnosed multiple myeloma (NDMM) in China. Methods: This study reviewed the clinical data of 421 patients with NDMM hospitalized in Beijing Jishuitan Hospital from April 2014 to February 2022. The sensitivity, specificity, accuracy, and Youden index of the two scores were calculated to quantify the thrombus risk assessment of VTE by the Padua and IMPEDE scores. The receiver operating characteristics curves of the two evaluation scores were drawn. Results: The incidence of VTE was 14.73%. The sensitivity, specificity, accuracy, and Youden index of the Padua score were 100%, 0%, 14.7%, and 0% and that of the IMPEDE score was 79%, 44%, 49.2%, and 23%, respectively. The areas under the curve of Padua and IMPEDE risk assessment scores were 0.591 and 0.722, respectively. Conclusion: IMPEDE score is suitable for predicting VTE within 6 months in patients with NDMM.

Abstract
Immunoglobulin (Ig) isotype switching in multiple myeloma (MM) is a rare form of clonal evolution. The aim of this study was to investigate the clinical features and prognostic significance of Ig isotype switching by observing Ig transformation in patients with relapse. A retrospective analysis was performed on 506 patients with newly diagnosed MM who were treated at our hospital from February 2005 to February 2020. The patients who experienced relapse were divided into the following four groups according to Ig phenotype: original paraprotein, complete isotype switching, light chain escape (LCE),and non-secretory clinical relapse. For comparative purposes with the original paraprotein group, the last three groups were pooled as the transformation group. Among the 506 included patients, 376 (74.3%) relapsed. Among them, 13/376 (3.5%) patients exhibited Ig isotype switching, including 3 with complete isotype switching, 3 with LCE, and 7 with non-secretory clinical relapse. Eleven remained sensitive to therapy, exhibiting at least a partial response. Seven patients survived for at least 20 months after relapse. The median overall survival time of the LCE, clinical relapse, and complete isotype switching groups were 6, 20, and 76 months, respectively, after recurrence. The clinical manifestations and Ig phenotypes of MM recurrence were different from those at the initial diagnosis in the 13 patients exhibiting Ig isotype switching. These differences vividly conveyed the heterogeneity of the clonal populations and provides direct clinical evidence for MM clonal evolution.

Abstract
ObjectivePrecise risk stratification is increasingly essential in the management of multiple myeloma (MM) as some standard-risk (SR) patients still exhibit similar poor outcomes as genetically high-risk (GHR) patients in the era of novel agents. It has recently been demonstrated that functional high-risk (FHR) patients, those with suboptimal response to first-line induction therapy or early relapse within 12 months, have identifiable molecular characteristics from the SR group in the CoMMpass dataset. However, these findings lack practical validation in the real world.MethodsMM cells purified by CD138 microbeads from newly diagnosed MM (NDMM) patients received fluorescence in situ hybridization and sequencing with a 92-gene Panel. Cytogenetic abnormalities defined GHR patients with t(4;14) or t(14;16) or complete loss of functional P53 or 1q21 gain and International Staging System (ISS) stage 3. SR group was patients who did not fulfill any criteria for GHR or FHR.ResultsThere were 145 patients with NDMM, 78 in the SR group, 56 in the GHR group, and 11 in the FHR group. In the FHR group, eight patients were suboptimal responses to induction therapy, and three relapsed within 12 months. We found that male patients, patients with extra-medullary plasmacytoma (EMD), circulating clonal plasma cells (CPC) ≥0.05%, and P53 mono-allelic inactivation were significantly higher in the FHR group compared to the SR group. After a median follow-up of 21.0 months, the median progression-free survival (PFS) and overall survival (OS) were 5.0 months, 19.1 months and 36.6 months in the FHR, GHR, and SR groups, respectively. Compared to the SR group, FHR patients had a higher frequency of mutations in MKI67, ERN1, and EML4. GO analysis showed that mutations in FHR were enriched for oxidative stress, chromosomal segregation, and hypoxia tolerance.ConclusionThe FHR found in the SR NDMM patient group has unique clinical features, including being male, with EMD and CPC, and genetic characteristics of mutations affecting oxidative stress, chromosome segregation, and hypoxia tolerance. In contrast to previous reports, our data suggested that patients with P53 mono-allelic inactivation should be classified in the GHR group rather than the FHR group.

Abstract
Purpose Vitamin D deficiency is frequent in patients with multiple myeloma (MM), however, its prognostic relevance in MM was rather inconclusive. We first investigated the association of vitamin D deficiency with abnormal bone and lipid metabolism in newly diagnosed multiple myeloma (NDMM), and next assessed the impact of serum ratio of vitamin D to carboxy-terminal telopeptide of type I collagen (β-CTX) on progression-free survival (PFS) and overall free survival (OS) in patients with NDMM. Methods The data of 431 consecutive patients with NDMM at Beijing Jishuitan Hospital from September 2013 to December 2022 were collected and retrospectively reviewed through our electronic medical record system. The measurement of 25-hydroxyvitamin D in the blood is an indicator of an individual's overall vitamin D status. Results The serum levels of vitamin D were negatively correlated with β-CTX in NDMM patients. Of note, positive correlation between vitamin D and cholesterol levels in the serum was found in this study. The cohort (n = 431) was divided into two groups based on the serum ratio of vitamin D to β-CTX. Compared to the group with a higher vitamin D to β-CTX ratio, the group with a lower vitamin D to β-CTX ratio (n = 257, 60%) exhibited hypocholesterolemia, inferior PFS and OS, along with increased cases of ISS stage-III and R-ISS stage-III, a higher number of plasma cells in the bone marrow, and elevated serum calcium levels. Consistent with this, multivariate analysis confirmed that the vitamin D to β-CTX ratio was an independent unfavorable indicator for survival in NDMM patients. Conclusion Our data demonstrated the ratio of vitamin D to β-CTX in the serum is a unique biomarker for NDMM patients to identify the high-risk cases with poor prognosis, which is superior to vitamin D itself for predicting PFS and OS in NDMM. Also, it is worth mentioning that our data on the connection between vitamin D deficiency and hypocholesterolemia might help clarify novel mechanistic aspects of myeloma development.

Abstract
Background Autologous hematopoietic stem cell (HSC) transplantation remains the recommended treatment for eligible patients with multiple myeloma (MM). Increasing the number of transplanted CD34+ cells shorten the time to hematopoietic reconstitution and increases the overall survival of patients. With the harvest of a sufficient CD34+ cell number being crucial, this study aimed to predict the factors that affect stem cell collection. Methods We conducted a retrospective study of 110 patients who were newly diagnosed with MM and underwent autologous HSC collection at Beijing Jishuitan Hospital between March 2016 and July 2022. Multiple factors were analyzed using the Mann-Whitney U tests for between-group comparisons. Differences were considered statistically significant at P < 0.05. Results We found that patient age affected stem cell collection significantly; for patients younger than 55 years, the number of CD34+ cells harvested may be ≥ 2 × 106/L, is unlikely to reach 5 × 106/L. Platelet count at initial mobilization was a predictor of the number of CD34+ cells collected. Collection may fail when the platelet count at initial mobilization is below 177 × 109/L and may be excellent when it is higher than 199 × 109/L. Conclusions This finding could guide us to predict the approximate number of CD34+ cells collected in advance during autologous transplant mobilization for MM and to decide in advance whether to apply plerixafor to improve the number of HSCs collected.

Abstract
Objective To use machine learning methods to explore overall survival (OS)-related prognostic factors in elderly multiple myeloma (MM) patients. Methods Data were cleaned and imputed using simple imputation methods. Two data resampling methods were implemented to facilitate model building and cross validation. Four algorithms including the cox proportional hazards model (CPH); DeepSurv; DeepHit; and the random survival forest (RSF) were applied to incorporate 30 parameters, such as baseline data, genetic abnormalities and treatment options, to construct a prognostic model for OS prediction in 338 elderly MM patients (>65 years old) from four hospitals in Beijing. The C-index and the integrated Brier score (IBwere used to evaluate model performances. Results The 30 variables incorporated in the models comprised MM baseline data, induction treatment data and maintenance therapy data. The variable importance test showed that the OS predictions were largely affected by the maintenance schema variable. Visualizing the survival curves by maintenance schema, we realized that the immunomodulator group had the best survival rate. C-indexes of 0.769, 0.780, 0.785, 0.798 and IBS score of 0.142, 0.112, 0.108, 0.099 were obtained from the CPH model, DeepSurv, DeepHit, and the RSF model respectively. The RSF model yield best scores from the fivefold cross-validation, and the results showed that different data resampling methods did affect our model results. Conclusion We established an OS model for elderly MM patients without genomic data based on 30 characteristics and treatment data by machine learning.

Abstract
BACKGROUND Hypercalcemia of malignancy (HCM) is a serious metabolic complication, and the highest rates are in multiple myeloma (MM). The cause of hypercalcemia in newly diagnosed multiple myeloma (NDMM) remains unknown. We sought to evaluate the prognostic impact and mechanism of hypercalcemia in patients with symptomatic NDMM. METHODS We studied all consecutive MM patients who were initially diagnosed and followed up at Beijing Jishuitan Hospital between February 2013 and December 2019; 357 patients were included in the retrospective analysis. RESULTS A total of 16.8% of MM patients presented with hypercalcemia at the time of MM diagnosis. The presence of hypercalcemia was associated with higher serum levels of β2 microglobulin, creatinine, phosphorus, uric acid, procollagen I N-terminal peptide, β-carboxy-terminal cross-linking telopeptide of type I collagen and osteocalcin, lower serum levels of hemoglobin, parathyroid hormone (PTH), and advanced ISS and R-ISS stages. Multivariate analysis showed that serum PTH, hemoglobin, creatinine, and uric acid levels were the main factors affecting hypercalcemia. The presence of hypercalcemia was associated with significantly inferior survival (40 months vs 57 months, p < 0.05) based on univariate analysis, and it remained an independent poor prognostic factor (HR: 1.854, 95% CI: 1.006-3.415, adjusted p = 0.048) in a multivariate model that included age and R-ISS stage. CONCLUSION This study shows that hypercalcemia is associated with poor survival and is caused by manifold factors with humoral effects and local bone destruction.

CD27- group (n = 93) had higher level of plasma cell proportion (37.00% vs 22.50%, p < .05), β2-MG (5.42 vs 3.20 mg/L, p < .05), calcium (2.45 vs 2.28 mmol/L, p < .05),higher percentage of ISS stage III (49.46% vs 22.22%, p < .05) and patients with ≥2 high-risk cytogenetics (24.73% vs 15.28%, p < .05) than CD27+ group (n = 72). After 4 cycles of chemotherapy, the overall response rate in CD27- group were lower than CD27+ group (56.67% vs 73.02%,p < .05). After a median follow-up of 18 months, progression-free survival was significantly shorter in CD27- group than in CD27+ group (22 vs 40 months, p < .05), so was overall survival (median OS not reached, p < .05). Gene sequencing showed more adverse mutations in CD27- group than CD27+ group.

Abstract
Objective: To explore the pathways of preeclampsia by investigating different effects of pravastatin (Pra) on and soluble FMS tyrosine kinase-1 (sFlt-1), placental growth factor (PlGF) and vascular endothelial growth factor (VEGF) in different preeclampsia (PE)-like mouse models. Methods: C57BL/6J mice were randomly subcutaneously injected with N-nitro-L-arginine methyl ester (L-NAME) or intraperitoneally injected with lipopolysaccharide (LPS) as PE-like mouse model, saline as normal pregnancy control (Con) respectively, daily at gestational 7-18 days. Pra was given daily at gestational 8-18 days in each model group and the mice were divided into Pra (L-NAME+Pra, LPS+Pra, Con+Pra) and saline (L-NAME+NS, LPS+NS, Con+NS) groups. Liver,placental tissue and blood of pregnant mice were collected on the 18th day of pregnancy. The levels of VEGF, PlGF and sFlt-1 in the liver, placenta and serum of mice in each group were compared by western blot, ELISA and real-time fluorescence quantitative PCR (RT-PCR). Results: (1) ELISA: Serum VEGF (205.70±3.43, 154.60±2.31) and PlGF (131.5±3.75, 101.50±4.31) levels were significantly increased in L-NAME+Pra group compared with L-NAME+NS group (all P<0.05). Serum VEGF (202.30±4.90, 144.50±6.71) and PlGF (121.50±3.86, 95.41±4.08) levels were significantly higher in LPS+Pra group than those in LPS+NS group (all P<0.05). Serum sFlt-1 level in LPS+Pra group was significantly lower than that in LPS+NS group (3.01±0.50, 776.60±80.06), serum sFlt-1 level in L-NAME+Pra group was significantly lower than that in L-NAME+NS group (2.60±0.06, 583.70±9.83; all P<0.05). (2) Western blot: the expression levels of PlGF (1.344±0.118, 0.664±0.143) and VEGF (1.34±0.12, 0.66±0.14) in the liver of mice in the L-NAME+Pra group were significantly higher than those in the L-NAME+NS group (all P<0.05), but the expression levels of PlGF and VEGF in the placenta of L-NAME+Pra group were not significantly different from those of L-NAME+NS group (all P>0.05). The expression levels of PlGF and VEGF in placenta and liver of pregnant mice in LPS+Pra group were not significantly different from those in LPS+N group (all P>0.05). (3) RT-PCR: the mRNA expression of PlGF and VEGF in placenta and liver of L-NAME+Pra group were not significantly different from those in L-NAME+NS group (all P>0.05). The mRNA expression levels of PlGF and VEGF in placenta and liver of LPS+Pra group were not significantly different from those of LPS+NS group (all P>0.05). Conclusions: Pra has different regulatory effects on vascular endothelial function in different PE-like models. It reveals that different pathogenesis and pathways exist in different PE-like changes.

Abstract
Objective: To investigate the modulation of long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD) expression by pravastatin in pre-eclampsia-like mouse model. Methods: C57BL/6J mice were randomly injected with N-nitro-L-arginine methyl ester (L-NAME) as pre-eclampsia-like model group (PE) or saline as normal pregnancy control group (Con) respectively, from gestational the 7th to 18th day. For each group, pravastatin (PE+Pra, Con+Pra group) or saline (PE+N, Con+N Group) was given from the 8th to 18th day of gestation, respectively. Liver and placenta of pregnant mice were collected on gestational day 18. The LCHAD protein expression and mRNA levels of liver and placenta were detected through western blot, immunohistochemistry and real-time quantitative PCR. Results: (1) The average arterial pressure of pregnant mice increased gradually from the 8th to 18th day in PE+N group, but decreased in PE+Pra group from gestational 10th day, 24 hour urinary protein levels in PE+N group [(1 494 ± 201) μg] were significantly higher than that in Con+N group [(935±128) μg, P<0.01], and also higher than that in PE+Pra group [(981±116) μg, P<0.01].(2) The results of western blot: the expression of LCHAD was significantly lower in PE+N group (liver: 0.64±0.11, placenta: 0.48±0.06) than that in Con+N group (liver: 1.06±0.10, placenta: 0.60±0.10), and lower than that in PE+Pra group (liver: 0.99±0.04, placenta: 0.60±0.08; all P<0.01).(3)The results of real-time quantitative PCR: the levels of LCHAD mRNA in liver and placenta in PE+N group (liver: 0.621±0.128, placenta: 0.646±0.129) were significantly decreased compared with Con+N group (liver: 1.007±0.130, placenta: 1.004±0.103; all P<0.01), but there was no significant difference between PE+Pra group (liver: 0.693±0.678, placenta: 0.662±0.183; P>0.05). (4) LCHAD protein was expressed widely and evenly in liver. The expression in placental cytotrophoblast and syncytial trophoblast cells located in outer layer of villous in labyrinth layer was the most. The expression of LCHAD was significantly lower in PE+N group (liver: 0.062±0.016, placenta: 0.147±0.018) than that in Con+N group (liver: 0.126±0.013, placenta: 0.183±0.024), and lower than that in PE+Pra group (liver: 0.111±0.017, placenta: 0.174±0.027; all P<0.05). Conclusion: Pravastatin could upregulate the LCHAD protein expression of liver and placenta in the pre-eclampsia-like mouse, which may be a mechanism to improve the clinical manifestations of pre-eclampsia.

Abstract
OBJECTIVE To observe the clinical characteristics of bone disease in patients with multiple myeloma (MM) and the clinical significance of monitoring bone metabolic markers. METHODS The data of 178 MM cases newly diagnosed in Beijing Ji Shui Tan Hospital from January 2009 to June 2014 were reviewed to analysis the types and classification of bone disease and to observe the clinical characteristics of patients with different grades of bone disease. The levels of bone metabolic markers total procollagen type Ⅰ N-terminal peptide (tPINP) and β C-terminal telopeptide of type Ⅰ collagen (β-CTX) were monitored regularly in the two years following treatment in 66 cases. RESULTS (1) Among the 178 newly diagnosed MM cases, 167 cases complained of pain in bones on first visit, 35 cases combined with hypercalcemia, 83 cases combined with osteoporosis, 154 cases combined with osteolytic bone destruction, and 73 cases combined with pathologic fracture. The most common osteolytic location was the spine. The most common fracture sites was the spine. (2) According to bone disease grading, the 178 cases were divided into group A (bone grade 0-2, n=51) and group B(bone grade 3-4, n=127). There were no significant differences between group A and group B in gender, median age, therapeutic effect/ineffec, median overall survival, median progress-free survival, mean serum lactic dehydrogenase, mean albumin, urine light chains and serum creatinine(all P>0.05). Compared with group A, group B had lower hemoglobin level[(99.78±29.93)vs (108.84±29.30) g/L], and higher blood calcium level[(2.47±0.40)vs (2.30±0.29) mmol/L], serum β2-microglobuin level[(6.04±4.84)vs (4.12±3.97)mg/L], and bone marrow plasma cells percentage(33.30%±24.87% vs 23.51%±22.67%)(all P<0.05). (3) Before treatment, the levels of β-CTX and tPINP in patients of group B(n=47) were higher than those in group A(n=19)(median 0.78 vs 0.42 μg/L, 60.95 vs 43.47 μg/L, both P<0.05). The ratio of β-CTX /tPINP in group B was higher than that in group A (median 0.017 vs 0.012, P<0.05). After chemotherapy for 3 months, there were no differences in the level of tPINP compared with that before treatment in both group A and group B (both P>0.05), the level of β-CTX decreased significantly compared with that before treatment in both groups(median 0.16 vs 0.42 μg/L, 0.26 vs 0.78 μg/L, both P<0.05); the ratio of β-CTX /tPINP decreased significantly compared with that before treatment in both group A and in group B(median 0.008 vs 0.012, 0.011 vs 0.017, both P<0.05). There were no differences in the level of β-CTX, tPINP and β-CTX/tPINP ratio after treatment for 6 months, 1 year and 2 years compared with that after 3 months in both group A and group B (all P>0.05). (4)All patients were divided into two groups according to the therapeutic effect: effective group included patients who reach the effect of partial remission or better remission(n=48), while ineffective group included patients who did not reach the effect of partial remission(n=18). Before treatment there were no differences in the level of β-CTX, tPINP and β-CTX/tPINP ratio between the effective groupand the ineffective group (all P>0.05). After chemotherapy for 3 months, there were no differences in the level of tPINP compared with that before treatment in both effective group and ineffective group (all P>0.05), but the level of β-CTX decreased significantly compared with that before treatment both in effective group and ineffective group (median 0.24 vs 0.60 μg/L, 0.44 vs 0.95 μg/L, both P<0.05). The ratio of β-CTX /tPINP decreased significantly compared with that before treatment both in effective group and ineffective group (median 0.005 vs 0.012, 0.005 vs 0.011, both P<0.05). There were no differences in the level of β-CTX, tPINP and β-CTX/tPINP ratio after treatment for 6 months, 1 year and 2 years compared with that for 3 months both in effective group and ineffective group (all P>0.05). CONCLUSIONS Pain in bones, osteolysis and pathological fracture are the most common clinical manifestations in myeloma-related bone disease. The severity of bone disease can reflect the tumor load, but may not affect the therapeutic effect and the overall survival. The bone metabolic markers tPINP and β-CTX can be used to evaluate the severity of myeloma-related bone disease at diagnosis and to monitor the effect of treatment for bone disease.
