Long-term correction of hemorrhagic diathesis in hemophilia A mice by an AAV-delivered hybrid FVIII composedof the human heavy chain and the rat light chain

《医学前沿（英文）》 2022年 第16卷 第4期   页码 584-595 doi: 10.1007/s11684-021-0844-7

摘要： Conventional therapies for hemophilia A (HA) are prophylactic or on-demand intravenous FVIII infusions. However, they are expensive and inconvenient to perform. Thus, better strategies for HA treatment must be developed. In this study, a recombinant FVIII cDNA encoding a human/rat hybrid FVIII with an enhanced procoagulant potential for adeno-associated virus (AAV)-delivered gene therapy was developed. Plasmids containing human FVIII heavy chain (hHC), human light chain (hLC), and rat light chain (rLC) were transfected into cells and hydrodynamically injected into HA mice. Purified AAV viruses were intravenously injected into HA mice at two doses. Results showed that the hHC+ rLC protein had a higher activity than the hHC+ hLC protein at comparable expression levels. The specific activity of hHC+ rLC was about 4- to 8-fold higher than that of their counterparts. Hydrodynamic injection experiments obtained consistent results. Notably, the HA mice undergoing the AAV-delivered hHC+ rLC treatment exhibited a visibly higher activity than those treated with hHC+ hLC, and the therapeutic effects lasted for up to 40 weeks. In conclusion, the application of the hybrid FVIII (hHC+ rLC) via an AAV-delivered gene therapy substantially improved the hemorrhagic diathesis of the HA mice. These data might be of help to the development of optimized FVIII expression cassette for HA gene therapy.

Tramadol reinforces antidepressant effects of ketamine with increased levels of brain-derived neurotrophic factorand tropomyosin-related kinase B in rat hippocampus

《医学前沿（英文）》 2012年 第6卷 第4期   页码 411-415 doi: 10.1007/s11684-012-0226-2

摘要：

Ketamine exerts rapid and robust antidepressant properties in both animal models and depressed patients and tramadol possesses potential antidepressant effects. Brain-derived neurotrophic factor (BDNF) is an important biomarker for mood disorders and tropomyosin-related kinase B (TrkB) is a high affinity catalytic receptor for BDNF. We hypothesized that tramadol pretreatment might reinforce ketamine-elicited antidepressant effects with significant changes in hippocampal BDNF and TrkB levels in rats. Immobility time of rats receiving different treatment in the forced swimming test (FST) was observed. Levels of BDNF and TrkB in hippocampus were measured by enzyme linked immunosorbent assay. Results showed that tramadol (5 mg/kg) administrated alone neither elicited antidepressant effects nor altered BDNF or TrkB level. However, pretreatment with tramadol (5 mg/kg) enhanced the ketamine (10 mg/kg) -elicited antidepressant effects and upregulated the BDNF and TrkB levels in hippocampus. In conclusion, tramadol pretreatment reinforces the ketamine-elicited antidepressant effects, which is associated with the increased levels of BDNF and TrkB in rat hippocampus.

Hepatitis B virus X protein upregulates tumor necrosis factor-α expression of rat mesangial cell

Hong-Zhu LU MD, Dan LIU BM, Qi-Hong FAN BM, Jian-Hua ZHOU MD,

《医学前沿（英文）》 2010年 第4卷 第1期   页码 106-111 doi: 10.1007/s11684-010-0004-y

摘要： Hepatitis B virus X protein (HBx), a 17-kd protein encoded by X gene of hepatitis B virus (HBV), has been shown to function as a transcriptional trans-activator of a variety of viral and cellular promoter/enhancer elements. The aim of the study is to investigate the extracellular regulated protein kinases (ERKs) pathway of HBx on glomerular mesangial cell (GMC) proliferation and tumor necrosis factor-α (TNF-α) expression. The HBV X gene was amplified by polymerase chain reaction (PCR), inserted into the eukaryotic expression vector pCI-neo and confirmed by restriction endonuclease digestion and sequence analysis. PCI-neo containing HBV X gene (pCI-neo-X) was then transfected into cultured GMC line via liposome. GMC proliferation, TNF-α and its mRNA expression were compared in the condition of with or without U0126 in culture media. HBx, ERK and p-ERK expression in GMCs was assessed by Western blotting. TNF-α mRNA expression was assessed by semi-quantitative reverse transcription-PCR (RT-PCR). TNF-α level in supernatants was measured by ELISA. GMC proliferation was detected by 3-(4,5-dimethylthiazol-2yl)-2,5-diphenyltetrazolium bromide (MTT) kit. The results showed that HBx expression was found in transfected GMCs and became prominent at 36th and 48th h after transfection whether with or without U0126 in culture media. TNF-α mRNA expression was significantly decreased in U0126 group compared with U0126-free group. TNF-α levels in supernatants in PCI-neo-X transfection without U0126 group were (189.0±18.1) and (172.3±24.3) pg/mL at 36th and 48th h after transfection, respectively. In contrast, TNF-α levels in supernatants with U0126 were (65.6±11.6) and (84.0±24.6) pg/mL at 36th and 48th h, respectively. The TNF-α levels in the latter groups were significantly lower than those in the former groups (<0.05). GMCs proliferation was also lower in added U0126 group at 36th and 48th h after transfection. From above, we can conclude that HBx could induce GMC proliferation and increase TNF-α mRNA expression and its protein production. HBx upregulates TNF-α expression and induces cell proliferation of GMC line partly through ERK signal transduction pathway.

Optimized human factor IX expression cassettes for hepatic-directed gene therapy of hemophilia B

null

《医学前沿（英文）》 2015年 第9卷 第1期   页码 90-99 doi: 10.1007/s11684-015-0390-2

摘要：

Gene therapy provides a potential cure for hemophilia B, and significant progress has been achieved in liver-directed gene transfer mediated by adeno-associated viral vectors. Recent clinical trials involving the use of a self-complementary adeno-associated virus serotype 8-human codon-optimized factor IX (AAV8-hFIXco) vector demonstrated encouraging efficacy with hFIX expression stabilized at 1% to 6% of normal level in patients, but safety concerns related to high vector doses are still present. Thus, further improvement of AAV vectors and hFIX expression cassette may positively contribute to the ultimate success of hemophilia B gene therapy. In this study, to obtain a higher expression level of hFIX that potentiates the coagulant capacity of recipients, human FIX expression vector was optimized by upgrading the codon adaption index and adjusting the GC content, inserting a Kozak sequence (GCCACC), and introducing a gain-of-function mutation, R338L (FIX Padua). The efficiency of the published and the presently constructed cassettes was compared through in vivo screening. In addition, the regulatory elements that control the FIX gene expression in these cassettes were screened for liver-specific effectiveness. Among all the constructed cassettes, scAAV-Pre-hFIXco-SIH-R338L, which was the construct under the control of the prothrombin enhancer and prealbumin promoter, resulted in the highest level of coagulant activity, and the expression levels of two constructed cassettes (scAAV-Chi-hFIXco-SIH-R338L and scAAV-Pre-hFIXco-SIH-R338L) were also higher than that of the published cassette (scAAV-LP1-hFIXco-SJ). In summary, our strategies led to a substantial increase in hFIX expression at the protein level or a remarkably elevated coagulant activity. Thus, these reconstructs of hFIX with AAV vector may potentially contribute to the creation of an efficacious gene therapy of hemophilia B.

《医学前沿（英文）》 2008年 第2卷 第3期   页码 283-285 doi: 10.1007/s11684-008-0053-7

摘要： The aim of this paper is to report a new coding variance of the gene, a candidate for autoimmune diseases. We found the variation in two families with type 2 diabetes mellitus by D-HPLC mutation screening method and confirmed our results by direct sequencing and PCR-RFLP. Although without changing the amino acid coding, the variance may have an effect on codon usage and play a role in disease development, such as type 2 diabetes mellitus. However, we cannot define the role of this variance because the frequency of the minor allele is low in the Chinese population and no homozygote of the variance was found. More research in multiple populations will be necessary to define the role of this variance.

《医学前沿（英文）》 2021年 第15卷 第2期   页码 208-220 doi: 10.1007/s11684-020-0795-4

摘要： New targeted therapies have been developed to overcome resistance to endocrine therapy (ET) and improve the outcome of HR /HER2 advanced breast cancer (ABC). We conducted a meta-analysis and systemic review on randomized controlled trials evaluating various targeted therapies in combination with ET in HR /HER2 ABC. PUBMED and EMBASE databases were searched for eligible trials. Hazard ratios (HRs) for progression-free survival (PFS), odds ratios (ORs) for objective response rate (ORR), clinical benefit rate (CBR), and toxicity were meta-analyzed. Twenty-six studies with data on 10 347 patients were included and pooled. The addition of cyclin-dependent kinase 4/6 inhibitors to ET significantly improved median PFS (pooled HR= 0.547, <0.001), overall survival (pooled HR= 0.755, <0.001), and tumor response rates (ORR, pooled OR= 1.478, <0.001; CBR, pooled OR= 1.201, <0.001) with manageable toxicities (pooled OR= 3.280, <0.001). The mammalian targets of rapamycin inhibitors and exemestane were not clinically beneficial for this pooled population including ET-naïve and ET-resistant patients. Moderate improvement in PFS (pooled HR= 0.686, <0.001) yet pronounced toxicities (pooled OR= 2.154, <0.001) were noted in the combination of phosphatidylinositol-4,5-bisphosphate 3-kinase inhibitors with fulvestrant. Future studies are warranted to optimize the population and the dosing sequence of these available options.

摘要： The effects of hypoxia on the invasion and the related protein expression of Hela cells and the role of hypoxia inducible factor-1α (HIF-1α) were investigated. The Hela cells were divided into three groups, namely, H (non-transfected Hela cells), H (pGenesil-1 empty plasmid-transfected Hela cells), and H (HIF-1α-shRNA plasmid-transfected Hela cells), and were cultured under hypoxia (1% O) and normoxia for 48h. The expression of HIF-1α, E-cadherin, β-catenin, and actin was detected using Western blot. The scratch test and the invasion assay were applied to examine the invasion in each group. The expression of HIF-1α, E-cadherin, and β-catenin in tumor grafts was assayed immunohistochemically. Western blot results revealed that the bands of HIF-1α, E-cadherin, β-catenin, and actin proteins were detected in the H and H groups under hypoxia for 48h. The expression of E-cadherin, β-catenin, and actin was detected in the H group under hypoxia for 48h, and normoxia. In the H, H, and H groups under normoxia, and the H group under hypoxia for 48h, no expression of HIF-1α was detectable. The scratch test showed that the invasive ability in the H group was significantly alleviated. Immunohistochemically, it was found that there was a significant difference in the expression of HIF-1α, E-cadherin, and β-catenin between the H and H groups (<0.05), but the difference was not significant between the H and H groups. It was concluded that the effects of hypoxia on the invasion of human cervical cancer Hela cells and the expression of related proteins (E-cadherin, β-catenin, and actin) depend on HIF-1α.

c-Fos expression in rat brainstem following intake of sucrose or saccharin

Ke Chen, Jianqun Yan, Jinrong Li, Bo Lv, Xiaolin Zhao

《医学前沿（英文）》 2011年 第5卷 第3期   页码 294-301 doi: 10.1007/s11684-011-0144-8

摘要： To examine whether the activation of brainstem neurons during intake of a sweet tastant is due to orosensory signals or post-ingestive factors, we compared the distribution of c-Fos-like immunoreactivity (c-FLI) in the nucleus of the solitary tract (NST) and parabrachial nucleus (PBN) of brainstem following ingestion of 0.25 M sucrose or 0.005 M saccharin solutions. Immunopositive neurons were localized mainly in the middle zone of the PBN and four rostral-caudal subregions of the NST. Intake of sucrose increased the number of FLI neurons in almost every subnucleus of the PBN (F = 7.610, = 0.023), in addition to the caudal NST at the level of the area postrema (F = 10.777, = 0.003) and the NST intermediate zone (F = 7.193, = 0.014). No significant increase in the number of c-Fos positive neurons was detected in response to saccharin ingestion, although there was a trend towards a modest increase in a few select NST and PBN nuclei. These results suggest that the PBN and NST may be involved in sweet taste perception and modulation of sweet tastant intake, but the significantly enhanced intensity of Fos expression induced by sucrose indicates that PBN/NST neuronal activity is driven by the integrated effects of sweet taste sensation and post-ingestive signals.

Proteome comparisons reveal influence of different dietary proteins on the development of rat jejunum

Mengjie LI, Chunbao LI, Shangxin SONG, Xinglian XU, Guanghong ZHOU

《农业科学与工程前沿（英文）》 2018年 第5卷 第3期   页码 362-372 doi: 10.15302/J-FASE-2018206

摘要：

This study compared proteome profiles and morphological changes of rat jejunum in response to different dietary proteins. Fifty male Sprague-Dawley rats were fed with casein (control), and isolated beef, pork, fish and chicken proteins for 14 days. Proteome analysis, histological observation and PEPT1 quantification of the jejunum were performed. The results indicated that rats fed with chicken proteins had higher PEPT1 mRNA and protein levels (P<0.05) but lower villus height and ratio of villus height to crypt depth (V/C ratio, P<0.05) than those fed with casein and pork protein. Label-free LC-MS/MS indicated that, as compared to casein, intake of chicken protein can regulate oligopeptide transport mainly by upregulating PEPT1 protein expression and reducing dipeptidyl-peptidase activity related to biological oxidation, and can reduce oligopeptide absorption capacity by regulating Hippo signaling pathway. Although intake of beef and fish proteins had no significant effect on PEPT1 expression, they altered several signaling pathways.

《医学前沿（英文）》 2013年 第7卷 第3期   页码 367-377 doi: 10.1007/s11684-013-0266-2

摘要：

This study aimed to modify a chronic ocular hypertension (OHT) rat model to screen for potential compounds to protect retinal ganglion cells (RGCs) from responding to increased intraocular pressure (IOP). A total of 266 rats were prepared and randomly grouped according to different time-points, namely, weeks 3, 8, 16, and 24. Rats were sedated and eye examination was performed to score as the corneal damage on a scale of 1 to 4. The OHT rat model was created via the injection of a hypertonic saline solution into the episcleral veins once weekly for two weeks. OHT was identified when the IOP at week 0 was≥6 mmHg than that at week -2 for the same eye. Viable RGCs were labeled by injecting 4% FluoroGold. Rats were sacrificed, and the eyes were enucleated and fixed. The fixed retinas were dissected to prepare flat whole-mounts. The viable RGCs were visualized and imaged. The IOP (meanβ±βSD) was calculated, and data were analyzed by the paired t-test and one-way ANOVA. The OHT model was created in 234 of 266 rats (87.97%), whereas 32 rats (12.03%) were removed from the study because of the absence of IOP elevation (11.28%) and/or corneal damage scores over 4 (0.75%). IOP was elevated by as much as 81.35% for 24 weeks. The average IOP was (16.68β±β0.98)βmmHg in non-OHT eyes (n = 234), but was (27.95±0.97)βmmHg in OHT eyes (n = 234). Viable RGCs in the OHT eyes were significantly decreased in a time-dependent manner by 29.41%, 38.24%, 55.32%, and 59.30% at weeks 3, 8, 16, and 24, respectively, as compared to viable RGCs in the non-OHT eyes (P<β0.05). The OHT model was successfully created in 88% of the rats. The IOP in the OHT eyes was elevated by approximately 81% for 24 weeks. The number of viable RGCs was decreased by 59% of the rats in a time-dependent manner. The modified OHT model may provide an effective and reliable method for screening drugs to protect RGCs from glaucoma.

Cloning of human XAF1 gene promoter and assay of its transcription activity in a variety of cell lines

Qiong CHEN, Qing YU, Yuhu SONG, Peiyuan Li, Ying CHANG, Zhijun WANG, Lifeng LIU, Wei WU, Jusheng LIN

《医学前沿（英文）》 2009年 第3卷 第2期   页码 148-152 doi: 10.1007/s11684-009-0032-7

摘要： To investigate the regulation of tumor suppressor XAF1 gene expression in digestive system cancers, we studied XAF1 gene promoter transcription activity and mRNA level in digestive system cancer cell lines (human hepatoma cell line HepG2, human colon cancer cell line LoVo, and human gastric cancer cell line AGS) and nontumor cell lines (human embryonic liver cell line L02 (L02 cells) and human embryonic kidney 293 cells [HEK293 cells]) as controls. 1395-bp-promoter fragment of XAF1 gene was amplified by polymerase chain reaction (PCR) and cloned into pGL3-basic vector and pEGFP-1 vector to assay its promoter transcription activity. The plasmids were transfected into a variety of cell lines by lipofectamine 2000. The promoter transcription activity was determined by dual-luciferase report assay, and enhanced green fluorescent protein (EGFP)-positive cells were detected by fluorescence microscope. The expression of XAF1 mRNA in HEK293 and L02 were significantly higher than that in any of the three digestive system cancer cell lines. The dual-luciferase reporter assay showed that the promoter transcription activity in digestive system tumor cell lines transfected with pGL3-XAF1p promoter was apparently lower than that of both HEK293 and L02 cells. Expression of green fluorescent protein (GFP) under the control of XAF1 promoter in the three digestive system cancer cell lines was lower than that of both HEK293 and L02 cells. The activities of pGL3-XAF1p in the three digestive system cancer cell lines after treatment with heat stress were significantly lower than those in the unstressed cells. The results suggested that remarkably down-regulated XAF1 mRNA expression in digestive system cancer cell lines may be due to loss of transcription activity of XAF1 promoter.

《医学前沿（英文）》 2008年 第2卷 第3期   页码 264-268 doi: 10.1007/s11684-008-0050-x

摘要： Domestic application of infrared patch clamp techniques on brain slices is limited. The key of the technique is to prepare high-quality brain slices. The present paper describes the preparation procedure of brainstem slices and the spontaneous firing properties of rat medial vestibular nucleus (MVN) neurons. By infrared differential interference contrast technique, neurons of rat MVN were visualized directly at the depth of 50–100 ?m underneath the surface of slices. Firing activities of MVN neurons were recorded by the whole-cell patch clamp technique in artificial cerebrospinal fluid (ACSF) and low Ca - high Mg fluid. The firing mode was more irregular and depressive in low Ca - high Mg fluid than in ACSF. According to the averaged waveform of action potentials, cells were classified as the neurons with monophasic after-hyperpolarization potential (AHP), and the neurons with biphasic AHP. The resting membrane potential (RMP), input resistance (Rin) and membrane capacitance (Cm) of neurons were recorded and compared between groups. With infrared videomicroscopy, patch clamp recordings could be made under direct observation in freshly prepared brainstem slices. The discharge activities of MVN neurons were spontaneous and the firing mode was modulated by extracellular calcium concentration. The basic membrane properties of two types of neurons were not significantly different, while the differences in waveform might play a role in the segregation between tonic and kinetic cells.

摘要： Leptin resistance is a main mechanism of acquired childhood obesity, and the suppression of long form of leptin receptor (OBRb) gene expression in diet-induced obese rats indicates that the down-regulation of OBRb gene expression plays a pivotal role in the mechanism of leptin resistance. The aim of the present study was to construct the lentiviral RNA interference (RNAi) vector of rat OBRb gene and evaluate the effects of siRNA on silencing OBRb gene expression. The target sequence of siRNA-OBRb was designed, and the complementary DNA containing both sense and antisense oligonucleotides was synthesized. After phosphorylation and annealing, these double-stranded DNA was cloned to pRNA-lentivector-VGFP to construct pRNA-Lenti-OBRb-VGFP recombinants with U6-containing promoter, target sequence and Poly III terminator. Then, the products were confirmed by electrophoresis and sequencing analysis, and the effects of RNAi on reducing gene expression were further confirmed by real-time polymerase chain reaction in transfected rat glioma cells expressing OBRb. The target sequence of siRNA-OBRb was successfully cloned to pRNA-lentivector-VGFP, and the RNAi protocol specifically reduced the expression of OBRb mRNA by approximately 80% compared with controls in transfected rat glioma cells. The successful construction of rat lentivirus vectors expressing OBRb-specific shRNA may be useful for further investigation .

System dynamics analytical modeling approach for construction project management research: A critical review and future directions

Xiaoxiao XU, Patrick X. W. ZOU

《工程管理前沿（英文）》 2021年 第8卷 第1期   页码 17-31 doi: 10.1007/s42524-019-0091-7

摘要： Building and infrastructure construction projects can be viewed as a complex system consisting of many subsystems. Over the last two decades, considerable researches that use system dynamics (SD) as an analytical and modeling approach exist to address construction project management issues. However, only few critical reviews have been conducted to provide an in-depth understanding of SD application in construction project management. Moreover, many studies have failed to apply SD accurately. Therefore, the present study aims to gain an understanding of the current state of play and future directions in applying SD method in construction project management research, by undertaking a comprehensive review of 105 relevant articles published from 1994 to 2018. These articles are analyzed in terms of annual publication rate, key papers and their contribution, critical issues in SD application, and research topics. A significant increase in the number of publications in the last five years has been observed. When applying SD method to model construction system, the following aspects must be carefully considered: Model boundary, model development, model test, and model simulation. In addition, SD has been applied in a wide range of research topics, including (1) sustainable construction; (2) design error, rework, and change management; (3) risk management; (4) resource management; (5) decision making; (6) hybrid modeling; (7) safety management; (8) PPP project; and (9) organization performance. Based on the review findings, this study discusses three future research directions, namely, integration of SD with other methods, uncertainty analysis, and human factor analysis. This study can help researchers gain an in-depth understanding of the critical issues in the application of SD in construction management and the state-of-the-art of SD research.
