Abstract
Objective: This retrospective, single-center study aimed to evaluate the efficacy and safety of programmed death-1 (PD-1) inhibitors, either as monotherapy or in combination with chemotherapy, in the management of relapse/refractory classical Hodgkin's lymphoma (R/R cHL) . Methods: A total of 35 patients with R/R cHL who received treatment at the Institute of Hematology and Blood Diseases Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College from September 2016 to December 2020 were enrolled in this study. Among them, 17 patients received PD-1 inhibitor monotherapy (PD-1 inhibitor group), while 18 patients received a combination of PD-1 inhibitor and chemotherapy (PD-1 inhibitor + chemotherapy group). Clinical data and follow-up information were retrospectively analyzed, and survival analysis was conducted using the Kaplan-Meier method and Cox proportional hazards model. Results: The median age of the 35 patients with R/R cHL was 29 years (range: 11-61 years), with 54.3% being male. According to the Ann Arbor staging system, 62.9% of patients presented with advanced (stage Ⅲ/Ⅳ) disease, and 48.6% had extranodal involvement. Before PD-1 inhibitor therapy, the median number of prior lines of therapy was 2 (range: 1-3). Objective responses were observed in 28 patients, including 22 complete response (CR) cases, resulting in an overall response rate (ORR) of 80.0% and a CR rate of 62.9%. Specifically, the ORR and CR rates were 64.7% and 58.8%, respectively, in the PD-1 inhibitor group and 94.4% and 66.7%, respectively, in the PD-1 inhibitor + chemotherapy group. Among the 18 patients who underwent sequential autologous hematopoietic stem cell transplantation (auto-HSCT) [13 CR and five partial response (PR) cases], eight patients received PD-1 inhibitor therapy after auto-HSCT as consolidation therapy. All patients maintained a CR status after transplantation, and they exhibited significantly improved progression-free survival (PFS) rates compared with those who did not undergo sequential auto-HSCT (4-year PFS rates: 100% vs 53.5% ; P=0.041). The incidence of immune-related adverse events was 29%, with only one patient experiencing grade≥3 adverse reactions, which indicated a favorable safety profile for the treatment approach. Conclusions: PD-1 inhibitor monotherapy demonstrates notable efficacy and sustained response in patients with R/R cHL. PD-1 inhibitors combined with chemotherapy significantly improve response rates. Additionally, for salvage therapy-sensitive patients, consolidation treatment with PD-1 inhibitors after auto-HSCT exhibits the potential for prolonging PFS.

Abstract
BACKGROUND The search for prognostic biomarkers indicating sensitivity to immunotherapy in lung adenocarcinoma patients has zeroed in on genes in the switch/sucrose non-fermentable (SWI/SNF) pathway. The mutational profiles of key genes are not clearly defined, however, and no comparisons have been conducted on whether mutations in the genes involved provide the same predictive value. METHODS In this study, analysis of clinical factors, tumor mutation burden (TMB), chromosomal instability, and co-alterations was conducted for 4344 lung adenocarcinoma samples. Independent online cohorts (N = 1661 and 576) were used to supplement the analysis with survival and RNA-seq data. RESULTS Mutational burden and chromosomal instability analysis showed that ARID family mutations (including ARID1A, ARID1B, or ARID2 mutations) and SMARC family mutations (including SMARCA4 or SMARCB1 mutations) display different profiles from wild-type (WT) samples (TMB: ARID versus WT: P < 2.2 × 10-16, SMARC versus WT: P < 2.2 × 10-16; CIN: ARID versus WT: P = 1.8 × 10-5, SMARC versus WT: P = 0.027). Both mutant groups have a higher proportion of transversions than transitions, whereas the ratio is more equal for wild-type samples. Survival analysis shows that patients with ARID mutations were more sensitive to immunotherapy treatment than wild-type and SMARC-mutated patients (P < 0.001 and P = 0.013, respectively), and multivariate Cox analysis reveals that the presence of ARID mutations is likely the main cause. CONCLUSIONS The research presented in this study shows that mutations in the ARID gene family, including ARID1A, ARID1B, and ARID2, are primarily responsible for the sensitive response to immunotherapy treatment in patients with lung adenocarcinoma.

Abstract
The inhibitory effect of water-tailored natural deep eutectic solvents (NADES) constructed from citric acid and trehalose with different amounts on the quality deterioration and oxidation of frozen-thawed (F-T) mirror carp (Cyprinus carpio L.) surimi was studied. NADES was obtained by citric acid to trehalose and the effect of moisture addition (v/v) on the structure, physicochemical, and anti-freezing capacity of NADES was assessed. NADES + 10 % H2O has relatively low viscosity (25 %) and strong freezing resistance. However, a 50 % H2O addition leads to the disappearance of the hydrogen bond. The addition of NADES effectively inhibits water loss, migration, and mechanical damage on F-T surimi. An inhibitory effect of 4 % (w/w) NADES on oxidation was verified by a decrease in carbonyl contents (17.4 %, 8.63 %) and TBARS (37.9 %, 15.2 %) of surimi compared with control (P < 0.05) and sucrose + sorbitol after 5F-T cycles, suggesting the potential of NADES as a cryoprotectant for the food industry.

Abstract
The dynamic changes in the postmortem quality of mirror carp (Cyprinus carpio L.) were investigated. With extended postmortem time, conductivity, redness, lipid oxidation, and protein oxidation all increased, while lightness, whiteness, and freshness decreased. At 4 h postmortem, the pH value reached a minimum (6.58), while the centrifugal loss and hardness reached a maximum (17.13% and 2539 g). Additionally, variations in mitochondria-related parameters during apoptosis were studied. Within 72 h postmortem, the content of reactive oxygen species initially decreased and subsequently increased; furthermore, there was a significant increase in the mitochondrial membrane permeability transition pore, membrane fluidity, and swelling (P < 0.05). Meanwhile, the cytosolic cytochrome c level decreased from 0.71 to 0.23, which indicated potential mitochondrial damage. Thus, mitochondrial dysfunction during postmortem aging can give rise to oxidation and the production of ammonia and amine compounds, which leads to flesh quality deterioration.

Abstract
The purpose of this study was to explore the tolerance mechanism of anammox consortia in microbial fuel cell (MFC) system at low temperature. Data showed that nearly 80 % total nitrogen removal was achieved after the temperature decreased from 30 °C to 15 °C. The nitrogenremovalrate (NRR) of the system was decreased by 26.3 %, from 0.441 kgN·m-3·d-1 at 30 °C to 0.325 kgN·m-3·d-1 at 15 °C. Isotope experiment in 15NH4+-containing reactor found that much more 29N2 were produced than 30N2, confirming that anammox was the main 15NH4+ removal pathway and electrochemical oxidation participate in this process. High throughput sequencing analysis indicated the low temperature stimulated the enrichment of heterotrophic bacteria, such as Comamonadaceae and Rhodobacteraceae. While the relative abundance of Candidatus Brocadia, typical anammox bacteria, decreased significantly. Kyoto Encyclopaedia of Genes and Genomes (KEGG) pathway analysis showed that the low temperature induced a more efficient expression in synthesis of unsaturated fatty acids (UFAs) and ABC membrane transports. This study indicates that anammox consortia are likely to maintain high nitrogen removal performance of MFC system by changing the proportion of membrane composition and EPS exportation.

Abstract
Objective: To evaluate the efficacy of VRD (bortezomib+lenalidomide+dexamethasone) in newly diagnosed multiple myeloma (NDMM) patients as well as the effect of the regimen on the long-term prognosis. Methods: The clinical characteristics, survival rates, response rates and minimal residual disease (MRD) of patients with NDMM at Institute of Hematology & Blood Diseases Hospital from January 1, 2013 to January 1, 2020 were retrospectively analyzed. Subgroup analysis was also performed among groups according to the cytogenetics and autologous stem cell transplantation (ASCT) of patients. Results: A total of 87 patients were retrospectively analyzed. The age[M(Q1,Q3)] of all patients was 56 (51, 61) years and males and females accounted for 58.6% (51/87) and 41.4% (36/87), respectively. The overall response rate (ORR) was 95.9% (71/74) after 2 courses of induction therapy, with 13.5% (10/74) achieving the deep response [complete response (CR) or better] and 51.3% (38/74) of patients achieving a very good partial response (VGPR) or better. After 4 courses of induction therapy, the ORR achieved 95.2% (60/63), and the proportions of the deep response and VGPR or better grew up to 46.0% (29/63) and 77.7% (49/63). According to the treatment, the patients (≤65 years old) were divided into transplantation group and non-transplantation group. After the induction therapy, 88.8% (32/36) of patients in the transplantation group achieved VGPR or better, and 55.5% (20/36) reached the deep response. After the transplantation, the proportion increased to 97.1% (34/35) and 77.2% (27/35), respectively(88.8% vs 97.1%,P=0.174;55.5% vs 77.2%,P=0.055), with the rate of undetectable MRD increasing from 44.4% (16/36) to 77.8% (28/36) (P=0.004). In the non-transplantation group, 74.2% (23/31) of patients achieved VGPR or better after 4 courses of induction therapy, 35.5% (11/31) of the patients achieved deep response and the rate of undetectable MRD was 37.0% (10/27). Compared with the non-transplantation group, transplantation was associated with a higher rate of complete response (89.5% vs 53.1%, P<0.001) and a lower rate of MRD detection(78.4% vs 55.2%, P=0.045). The median follow-up time of all patients was 26.3 months (20.8, 33.8). The median progression-free survival and overall survival were not reached. The three-year PFS and OS rates were 78.4% and 87.2%, respectively. None of the standard-risk group, the high-risk group, the transplantation group and non-transplantation group achieved the median PFS and OS. Conclusions: VRD regimen has a promising efficacy and results in a substantial survival benefit. ASCT after VRD induction therapy is associated with higher rate of deep response, higher rate of undetectable MRD and longer survival.

Abstract
The clinical characteristics, laboratory results, response to treatment, and prognosis of 46 macrofocal multiple myeloma(MFMM) patients at our center from January 2013 to December 2019 were analyzed retrospectively. The other 92 patients were selected as matched-controls based on diagnostic period and treatment. Among the 1 137 MM patients, 46 patients met the definition criteria of MFMM (4.0%), with median age 56 years, which was not statistically different from whole MM population (P=0.066). According to the international staging system (ISS) and Revised ISS, the proportion of patients with advanced stage in MFMM group was less common than that of controls (P<0.05). More plasmacytomas in MFMM patients were presented (43.5% vs. 18.5%, P<0.05). Regarding cytogenetic abnormalities, there were minor patients manifesting high-risk features in MFMM group (15.8% vs. 32.2%, P=0.058). Translocation(11;14) could be detected in 32.4% MFMM patients and 9.4% typical myeloma patients (P<0.05). The treatment regimens were comparable. As to the best response of treatment, the complete response (CR) rate in MFMM group was significantly higher than that of controls (78.3% vs. 60.9%, P<0.05). The median follow-up time was 37.9 months. The median progression-free survival in MFMM and control groups were 77.5 vs. 39.8 months, respectively (P<0.05). The overall survival (OS) of MFMM patients was significantly longer (not reached vs. 68.2 months, P<0.05).

Abstract
Digital twins, customized simulation models pioneered in industry, are beginning to be deployed in medicine and healthcare, with some major successes, for instance in cardiovascular diagnostics and in insulin pump control. Personalized computational models are also assisting in applications ranging from drug development to treatment optimization. More advanced medical digital twins will be essential to making precision medicine a reality. Because the immune system plays an important role in such a wide range of diseases and health conditions, from fighting pathogens to autoimmune disorders, digital twins of the immune system will have an especially high impact. However, their development presents major challenges, stemming from the inherent complexity of the immune system and the difficulty of measuring many aspects of a patient’s immune state in vivo. This perspective outlines a roadmap for meeting these challenges and building a prototype of an immune digital twin. It is structured as a four-stage process that proceeds from a specification of a concrete use case to model constructions, personalization, and continued improvement.

Abstract
The accurate diagnosis of burn wound depth is particularly important for evaluating the disease prognosis of burn patients. In the past, the diagnosis of burn wound depth often relied on the subjective judgment of doctors. With the continuous development of diagnostic technology, the methods for judging the depth of burn wound have also been updated. This paper mainly summarizes the research progress in the applications of indocyanine green angiography, laser Doppler imaging, laser speckle contrast imaging, and artificial intelligence in the diagnosis of burn wound depth, and compares the advantages and disadvantages of these techniques, so as to provide ideas for accurate diagnosis of burn wound depth.

Abstract
The aim of this study was to investigate the surface temperature, moisture migration, muscle shrinkage and microstructure of beef jerky during hot air multi-stage drying. Temperatures were sequentially increased from 40 to 50 to 60 °C, and corresponding times were 0.5 h - 1 h - 2.5 h, 0.5 h - 2 h - 1.5 h, 1 h - 1 h - 2 h and 1 h - 2 h - 1 h in 4 groups. With increasing temperature, moisture content and diffusivity of the sample decreased, the surface temperature, moisture migration, muscle shrinkage and the gaps (spacing) between muscle fibres increased. The jerky in groups 3 and 4 attained high overall acceptability. The jerky dried at 40 °C for 1 h, 50 °C for 1 h and 60 °C for 2 h had highest quality. The results cover the range of temperature and time used in beef drying and can be used to optimize the drying process of beef.

Abstract
目的 探讨硼替佐米中枢神经系统(CNS)毒性的临床特点、诊断和治疗。 方法 报道5例由硼替佐米引起的CNS毒性患者并结合现有文献探讨其临床特点。 结果 5例患者中有4例在应用硼替佐米后出现了中枢性发热,主要表现为持续性高热、周身无汗、未能找到感染病灶、对退热药不敏感,停用硼替佐米后症状好转。4例患者中有3例伴随顽固性低钠血症,1例明确诊断为抗利尿不当综合征(SIAD),可能是硼替佐米同时影响了下丘脑体温调节中枢和抗利尿激素神经分泌细胞所致。1例患者诊断为可逆性后部脑病综合征(PRES),表现为应用硼替佐米后出现意识障碍,头CT示双侧半卵圆中心白质密度减低,停用硼替佐米后患者症状消失且未再复发。此外,我们还发现血小板计数可能与硼替佐米CNS毒性的严重程度相关。 结论 硼替佐米的CNS毒性非常罕见,表现为3种形式:SIAD、PRES和中枢性发热,及时识别和治疗对于预防不可逆的神经并发症非常重要。

Abstract
目的 探讨24个月内疾病进展(POD24)对伴骨髓侵犯的脾边缘区淋巴瘤(SMZL)患者总生存的影响,比较POD24与非POD24患者的临床特征。 方法 回顾性分析2002年1月至2017年1月中国医学科学院血液病医院收治的有治疗指征且经过正规治疗的伴骨髓侵犯的SMZL患者,选取随访时间足以对POD24进行判断的患者(排除因非进展因素发生死亡的患者),进行预后评估及临床特征比较。 结果 共入组患者106例,中位年龄57(25~79)岁。①临床特征:全部患者均有骨髓侵犯和脾肿大,其中巨脾59.4%(63/106),肝大14.8%(15/101);复杂核型22.7%(18/79),13q缺失5.1%(4/78),11q缺失1.3%(1/72),17p缺失2.5%(2/80),12号染色体三体(CEP12)7.5%(4/53)。②生存分析:单因素分析提示POD24、HGB<100 g/L以及CEP12为与总生存相关的不良预后因素;多因素分析提示仅POD24有独立预后意义[HR=20.116(95%CI 2.226~181.820),P=0.008]。③亚组分析:POD24患者较非POD24患者起病时纵隔淋巴结肿大的发生率(63.6%对18.9%,P=0.005)及复杂核型发生率(50.0%对17.9%,P=0.024)明显增高;腹腔淋巴结肿大、贫血、血小板减少、白蛋白下降以及乳酸脱氢酶增高的发生率在POD24患者中更高,与非POD24患者相比差异无统计学意义(P>0.05)。 结论 POD24为影响伴骨髓侵犯的SMZL患者总生存的独立预后不良因素,起病时伴纵隔淋巴结肿大及复杂核型的患者发生POD24比例更高。

Abstract
OBJECTIVE To investigate the influence of VEGF/BMP-2 on the proliferation and osteogenic differentiation of rat bone mesenchymal stem cells BMSCs) on PLGA/gelatin composite scaffold. MATERIALS AND METHODS Randomly-oriented nanofibers with different ratios of Poly Lactic-co-Glycolic Acid (PLGA)/gelatin were produced through electrospinning. The mixture of nanofibers and BMSCs was pipetted onto the surface of the scaffolds, and BMSCs/PLGA/gelatin composite was obtained. The surface morphology, chemical structure, hydrophilicity and mechanical property of PLGA/gelatin nanofibers were revealed by scanning electron microscope. In vitro release kinetics of bone morphogenetic protein (BMP-2) and vascular endothelial growth factor (VEGF) were studied using ELISA kits. The cell adhesion, growth and proliferation of BMSCs on scaffolds were observed by scanning electron microscopy. The CCK-8 assay was used to evaluate the effects of VEGF/BMP-2 slow release system on the proliferation of BMSCs on scaffolds. RT-PCR was used to examine the activities of alkaline phosphatase (ALP), runt-related transcription factor 2 (RUNX-2), and osteocalcin (OCN). RESULTS In each group of cells in the in-vitro experiment, through electron microscope scanning, fiber scaffolds were interconnected three-dimensional reticular structure, BMSCs firmly attached to the fiber surface and internal stent, cells experienced a long spindle, polygon change, and branch-like protrusions on the cell surface were connected. Under the electron microscope, cell proliferation curve and osteogenesis markers (ALP, RUNX-2, OCN) expression in the dual factor group on cell adhesion, proliferation and differentiation were much better than those of blank control group and single factor groups. CONCLUSIONS In the successfully constructed gelatin/PLGA nanofiber scaffold, VEGF and BMP-2 can be sequentially released, during which VEGF and BMP-2 can promote the adhesion, proliferation, and differentiation of BMSCs.

Abstract
Multiple myeloma (MM) is the second most prevalent hematologic malignancy. Aberrant microRNAs (miRNAs) expression has been shown to be involved in the pathogenesis of MM. In this study, we further demonstrated that miR-137 was significantly downregulated in MM and negatively correlated with clinical prognosis. Moreover, we described the epigenetic regulation of miR-137 and its association with progression-free survival in MM patients. Furthermore, overexpression of miR-137 in MM cell line (miR-137 OE) increased its sensitivity to bortezomib and eprirubicin in vitro. Also, some high-risk genetic abnormalities in MM, including deletion of chromosome 1p22.2, 14q or 17p13, and gain of chromosome 1p22.2 were detected in NCI-H929 empty vector (NCI-H929 EV) treated cells but not in the NCI-H929 miR-137 overexpression (NCI-H929 miR-137 OE) cells. Luciferase reporter assays demonstrated that miR-137 targeted AURKA. Ectopic expression of miR-137 strongly reduced the expression of AURKA and p-ATM/Chk2 in MM cells, and increased the expression of p53, and p21. Importantly, miR-137 overexpression together with bortezomib treatment significantly inhibited tumor growth in MM xenograft model. Taken together, this study demonstrates that miR-137 is epigenetically silenced in MM, and overexpression of miR-137 could reduce drug resistance and overcome chromosomal instability of the MM cells via affecting the apoptosis and DNA damage pathways.

Abstract
Agent-based models (ABMs) have become an increasingly important mode of inquiry for the life sciences. They are particularly valuable for systems that are not understood well enough to build an equation-based model. These advantages, however, are counterbalanced by the difficulty of analyzing and using ABMs, due to the lack of the type of mathematical tools available for more traditional models, which leaves simulation as the primary approach. As models become large, simulation becomes challenging. This paper proposes a novel approach to two mathematical aspects of ABMs, optimization and control, and it presents a few first steps outlining how one might carry out this approach. Rather than viewing the ABM as a model, it is to be viewed as a surrogate for the actual system. For a given optimization or control problem (which may change over time), the surrogate system is modeled instead, using data from the ABM and a modeling framework for which ready-made mathematical tools exist, such as differential equations, or for which control strategies can explored more easily. Once the optimization problem is solved for the model of the surrogate, it is then lifted to the surrogate and tested. The final step is to lift the optimization solution from the surrogate system to the actual system. This program is illustrated with published work, using two relatively simple ABMs as a demonstration, Sugarscape and a consumer-resource ABM. Specific techniques discussed include dimension reduction and approximation of an ABM by difference equations as well systems of PDEs, related to certain specific control objectives. This demonstration illustrates the very challenging mathematical problems that need to be solved before this approach can be realistically applied to complex and large ABMs, current and future. The paper outlines a research program to address them.

Abstract
OBJECTIVE We investigate the effects of bone morphogenetic protein-7 (BMP-7) on models with silica-induced and macrophage-mediated fibrosis and its possible mechanisms in vitro. METHODS Rat alveolar II epithelial (RLE-6TN) cells were incubated with the supernatant of mouse macrophage-like cells (RAW264.7) and treated with 0, 25, 50, and 100 μg/mL silica. Using Western blotting, the epithelial markers (surfactant proteins-C and E-cadherin) and the mesenchymal markers (fibronectin (FN) and viminten (Vim)) were detected. After neutralizing the BMP-7, the progress of fibrosis was assessed by the content of hydroxyproline (Hyp) and collagen I, III protein levels as well as the Smad signaling pathway proteins, including phosphorylated Smad1/5(P-Smad1/5) and phosphorylated Smad2/3(P-Smad2/3). Collagen I was also identified by immunofluorescence and pretreated with SB-431542, LDN-193189, or anti-BMP-7-neutralizing antibody. In addition, the levels of matrix metalloproteinase-2 (MMP-2) and MMP-9 were detected using Western blotting. RESULTS The model of RLE-6TN cells was established successfully, the expressions of Vim, FN, MMP-2, and MMP-9 were upregulated, while the concentration of silica is increased. Neutralizing BMP-7 stimulated the decrease of P-Smad1/5 and the increase of P-Smad2/3, as well as the collagen I, collagen III, FN, and Hyp via Smad signaling pathway. Furthermore, pretreated with LDN-193189 or anti-BMP-7-neutralizing antibody, the expression of collagen I was increased, yet it was decreased with SB-431542 intervention. CONCLUSION The activated BMP/Smad and suppressed transforming growth factor-β/Smad pathways could suppress silica-induced fibrosis via a MMP-dependent mechanism. BMP-7 is expected to be the optimized strategy of delaying the interstitial changes.

Abstract
The anti-CD38 monoclonal antibody SAR650984 (SAR) is showing promising clinical activity in treatment of relapsed and refractory multiple myeloma (MM). Besides effector-mediated antibody-dependent cellular cytotoxicity and complement-mediated cytotoxicity, we here define molecular mechanisms of SAR-directed MM cell death and enhanced anti-MM activity triggered by SAR with Pomalidomide (Pom). Without Fc-cross-linking agents or effector cells, SAR specifically induces homotypic aggregation (HA)-associated cell death in MM cells dependent on the level of cell surface CD38 expression, actin cytoskeleton and membrane lipid raft. SAR and its F(ab)'2 fragments trigger caspase 3/7-dependent apoptosis in MM cells highly expressing CD38, even with p53 mutation. Importantly, SAR specifically induces lysosome-dependent cell death (LCD) by enlarging lysosomes and increasing lysosomal membrane permeabilization associated with leakage of cathepsin B and LAMP-1, regardless of the presence of interleukin-6 or bone marrow stromal cells. Conversely, the lysosomal vacuolar H+-ATPase inhibitor blocks SAR-induced LCD. SAR further upregulates reactive oxygen species. Pom enhances SAR-induced direct and indirect killing even in MM cells resistant to Pom/Len. Taken together, SAR is the first therapeutic monoclonal antibody mediating direct cytotoxicity against MM cells via multiple mechanisms of action. Our data show that Pom augments both direct and effector cell-mediated MM cytotoxicity of SAR, providing the framework for combination clinical trials.

Abstract
OBJECTIVE The mesenchymal stem cells (MSCs), which were distributed in the bone marrow stroma, become ideal progenitor cells in bone tissue engineering because of their convenient isolation, small injury when obtained, and strong osteogenic capacity. The osteogenic differentiation of MSCs, which is indicated by the increased alkaline phosphatase (ALP) activity and the enhanced accumulation of collagen, could be induced by a strong osteogenic capacity biological factor termed bone morphogenetic protein-7 (BMP-7). Although the chemically synthesized BMP-7 was widely applied to study the osteogenic differentiation of MSCs, transferring and expressing BMP-7 gene in target cells is more desirable, especially for gene therapy, given the advantages and convenience on the stable expression of BMP-7. The aim of this study was to determine whether recombinant BMP-7-expressing MSCs would induce bone formation in vitro. MATERIALS AND METHODS BMP-7 gene was cloned from human placental tissue to construct a recombinant eukaryotic expression plasmid carrying BMP-7 gene by conjugating with eukaryotic expression vector pcDNA3.1. MSCs were isolated from rabbit bone marrow and cultured in vitro. Then they were divided into 3 groups: pcDNA3.1-BMP-7-transfected, pcDNA3.1-transfected, and untransfected. Human healthy fresh placental tissue was provided by the Department of Gynaecology and Obstetrics, Second Affiliated Hospital of Harbin Medical University. Written informed consent was obtained from the women. One healthy male New Zealand rabbit was provided by the Laboratory Animal Center, Harbin Medical University. RESULTS A significant increase of ALP activity was detected in the supernatant of pcDNA3.1-BMP-7 transfected MSCs, and the enhanced collagen accumulation, which was inferred by the increased hydroxyproline content and RT-PCR. CONCLUSIONS These results implied that BMP-7 gene was expressed in MSCs sufficiently and was involved in inducing differentiation of MSCs into osteoblast.

Abstract
AIM The accuracy and clinical value of circulating microRNA-21 (miR-21) were assessed as a novel diagnostic biomarker of colorectal cancer (CRC). METHOD Medline/PubMed, EMBASE, the Cochrane Library databases and grey literature (Google scholar; British Library) were searched up to 29 September 2014 for eligible studies of the association between blood-based miR-21 and a diagnosis of CRC. Quality Assessment of Diagnostic Accuracy Studies (QUADAS) was employed to assess the quality of the included studies by two investigators. Stata12.0 and Meta-DiSc1.4 software were applied to test the heterogeneity using Cochran's Q test and I(2) statistics and to perform the meta-analysis. RESULTS Seven studies with 676 CRC patients and 417 controls were included in the meta-analysis. All were of high quality (QUADAS scores 12 or 13). For miR-21, the pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio to predict CRC were 75% [95% confidence interval (CI) 63-83%], 84% (95% CI 79-87%), 4.61 (95% CI 3.38-6.29), 0.30 (95% CI 0.20-0.46) and 16.89 (95% CI 7.56-37.73) after using a random-effects model analysis. The area under the summary receiver operating characteristic curve was 0.86 (95% CI 0.83-0.89). CONCLUSION The results suggest that circulating miR-21 is a biomarker with moderate sensitivity and specificity for CRC.

Abstract
Different single-strand conformation polymorphism (SSCP) patterns of the 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGCR) gene amplified by six pairs of primers were sequenced. Comparisons among the six nucleotide sequences of three genotypes revealed three base substitutions (G-789-A, C-937-G, and A-2316-C) in the HMGCR gene. The genotypes of single nucleotide polymorphism 1 (SNP1) and SNP3 were significantly associated with the number of eggs (P < 0.01), and the different genotypes of SNP2 did not significantly influence the number of eggs. The genotypes of all three SNPs were not related to the hatching rate of fertilized eggs (P > 0.05). Of the three SNPs of the HMGCR gene, those genotypes with lower plasma very low-density lipoprotein (VLDL) concentrations had higher egg production. The 300-day egg production of the six studied haplotypes showed three levels (P < 0.01). The ADE and ACE haplotypes showed lower egg production than the other haplotypes. The ADE haplotype had the highest plasma VLDL concentration, and the ACE haplotype had the lowest plasma VLDL concentration. We concluded that specific variants of the HMGCR gene are associated with chicken egg production, and haplotypes with higher and lower plasma VLDL concentrations showed lower egg production than other haplotypes.

Abstract
The objective of this study was to develop a population pharmacokinetic model for rifampin in elephants. Rifampin concentration data from three sources were pooled to provide a total of 233 oral concentrations from 37 Asian elephants. The population pharmacokinetic models were created using Monolix (version 4.2). Simulations were conducted using ModelRisk. We examined the influence of age, food, sex, and weight as model covariates. We further optimized the dosing of rifampin based upon simulations using the population pharmacokinetic model. Rifampin pharmacokinetics were best described by a one-compartment open model including first-order absorption with a lag time and first-order elimination. Body weight was a significant covariate for volume of distribution, and food intake was a significant covariate for lag time. The median Cmax of 6.07 μg/mL was below the target range of 8-24 μg/mL. Monte Carlo simulations predicted the highest treatable MIC of 0.25 μg/mL with the current initial dosing recommendation of 10 mg/kg, based upon a previously published target AUC0-24/MIC > 271 (fAUC > 41). Simulations from the population model indicate that the current dose of 10 mg/kg may be adequate for MICs up to 0.25 μg/mL. While the targeted AUC/MIC may be adequate for most MICs, the median Cmax for all elephants is below the human and elephant targeted ranges.

Abstract
OBJECTIVES The multipotent mesenchymal stem cells (MSCs) were distributed in the bone marrow stroma, and could generate all of the different skeletal cell lineages. The osteogenic differentiation of MSCs, which is indicated by the increased alkaline phosphatase (ALP) activity and the enhanced accumulation of collagen, could be induced by a tetradecapeptide termed osteogenic growth peptide (OGP). It has been hypothesized that the OGP induces the osteogenic differentiation of MSCs probably through regulating the fibroblast growth factor signaling pathways. Although the chemically synthesized OGP was widely applied to study the osteogenic differentiation of MSCs, transferring and expressing OGP gene in target cells is more desirable, especially for gene therapy, given the advantages and convenience on the stable expression of OGP. MATERIALS AND METHODS In this study, we attempt to test the effect of OGP gene transfection; we constructed a eukaryotic expression vector, pcDNA3.1-OGP, which contained the OGP-coding DNA fragment. Subsequently, the vector was transfected into the rabbit MSCs. RESULTS A significant increase of ALP activity was detected in the supernatant of pcDNA3.1-OGP transfected MSCs, and the enhanced collagen accumulation, which was inferred by the increased hydroxyproline content and RT-PCR. CONCLUSIONS These results implied that transfecting the OGP-expressing vectors into MSCs might induce the osteogenic differentiation of MSCs.

Abstract
Abstract
Introduction: Breast tumors consist of heterogenous cell populations with dominant features that can change over time. The development of resistance to previously effective therapies is an example of tumor evolution in response to selective pressure, where the differential composition of cells within a tumor may predispose to identifiable patterns of tumor growth and progression. We employ a previously developed computational model of ductal epithelial dynamics (the Duct Epithelial Agent Based Model or DEABM), able to reproduce known rates of tumorigenesis in both wild-type and BRCA1 populations, to investigate the putative population dynamics of ER+ tumors in response to decreased estrogen availability (DEA).
Methods: The DEABM is composed of computational agents representing individual cells (luminal and myoepithelial cells, their progenitor cells and fibroblasts) behaving based on rules established from published cellular and molecular mechanisms. Cells implement DNA damage/repair, cell division in response to estrogen/local growth factors, and apoptosis. Unrepaired DNA damage impacts genomic integrity, including eight representative oncogenes and tumor suppressors affecting critical pathways previously implicated in breast cancer (BRCA1, P53, E-cadherin, RUNX3, Myc, TGF-beta, MMP-3 and Telomerase). ER+ tumors were generated in 40 year simulations of wild-type and BRCA1 populations and subjected to DEA (90% reduction in estrogen effect targeted to ER+ cells, which could generally represent endocrine therapy for breast cancer.) Cell populations were characterized by mutation profiles, ER status, and response to estrogen suppression. Simulations were continued until development of DEA resistance, identified by reversal of growth suppression, and the mutations present at that point were analyzed for change.
Results: 3500 DEABM simulations over 40 years generated 69 wild-type ER+ tumors and 119 BRCA ER+ tumors. Of these 25% of wild-type ER+ tumors were sensitive to DEA vs. 35% of BRCA1 tumors, consistent with previously reported response rates. The percentage of ER+ cells was higher in initially sensitive tumors than in initially resistant tumors (84% vs. 66%, p = .001). Tumors initially resistant to DEA were more likely to carry mutations in the genes p53, E-cadherin and Myc (p = .001). Sensitive tumors acquired a significant increase in mutations during the interval between responsiveness to DEA and development of resistance (p = .001). Lastly, sensitive BRCA1 carriers were more likely to convert from ER+ to ER- status (p = .001).
Discussion: The DEABM generated simulated breast tumors with intra-tumoral heterogeneity that demonstrate varied responsiveness to DEA, similar to what is observed clinically. These results suggest there may be definable patterns of tumor evolution in response to DEA that could potentially guide the development or sequencing of therapeutic regimens. Computational models such as the DEABM can aid in visualizing molecular data in a dynamic form and allow researchers to carry out “thought experiments” concerning tumor behavior and intervention effect.
