     Building a professional clinical research team inside hospitals is in favor improving their research abilities, accelerating the clinical discipline construction, improving their comprehensive influence. Also it fits the objective of general hospital development under gate-keeping system. Now in domestic, the percentage of professional research staff in large hospitals accounts was much less than the international level. The main reasons included the misunderstanding of constructing the research-oriented hospitals, insufficient human resources enrollment, less attractive environment to the highlevel researchers and the absence of relevant degree training programs. To enhance the construction of research-oriented hospitals, it’s of key importance to build the professional research team in hospitals. Besides, the hospital has to update management conception, broaden the channels of talent cultivation, grasp the development of the subject accurately and interact with the basic medicine and public health subject, increase the financial investment and perfect the relevant management regulations.

    doi: 10.3969/j.issn.1674-8115.2017.06.002

    Abstract ( 945 )   PDF (8069KB) ( 858 )  

     Objective · To demonstrate the effect of TRIM59 on gliomagenesis and the molecular mechanism.  Methods · TRIM59 protein expression in glioma specimens was analyzed by immunohistochemical staining, and in several glioma cell lines by Western blotting and quantative PCR. After TRIM59 was knocked down by shRNAs, cell proliferation, migration, colony formation, and orthotopic xenograft brain tumor development were detected. The signaling pathway of TRIM59 in gliomas was also explored by RNA-Seq and KEGG PATHWAY analyses.  Results · The levels of TRIM59 protein expression in clinical glioma specimens were positively correlated with glioma malignancy. TRIM59 was highly expressed in LN229 and U87 glioma cells compared with normal human astrocytes. Knockdown of TRIM59 in these two cell lines with lentivirus-mediated shRNAs inhibited their proliferation, migration, and colony formation. Compared with the control xenograft models, knockdown of TRIM59 significantly inhibited glioma tumor growth. RNASeq and KEGG PATHWAY analyses identified that TRIM59 knockdown down-regulated 306 genes, among which PI3K/AKT signal pathway-related genes were the most. Moreover, TRIM59 knockdown suppressed AKT phosphorylation, whereas overexpression of a constitutively actived AKT (Myr-AKT) rescued TRIM59 knockdown-inhibited cell proliferation.  Conclusion · TRIM59 is a new glioma oncogene, which may take effect through activating PI3K/ AKT signaling pathway.

    Abstract ( 1236 )   PDF (8022KB) ( 992 )  

     Objective · To determine the expression of miRNA-7 in TWEAK-stimulated macrophages and their secreted exosomes; to investigate the role of exosomal miRNA-7 from TWEAK-stimulated macrophages in modulating the metastasis of epithelial ovarian cancer (EOC) cells.  Methods · Real-time PCR analysis was used to determine the miRNA-7 expression in TWEAK-stimulated macrophages, their exosomes and recipient HO8910-PM cells. The activity of EGFR signaling pathway in HO8910-PM cells was detected by Western blotting analysis. AntagomiR-7 was used to downregulate the miRNA-7 expressions in macrophage exosomes and then their effect on metastasis of HO8910-PM cells was examined by transwell assay.  Results · TWEAK increased the levels of miRNA-7 in macrophages and their secreted exosomes and also resulted in an elevated level of miRNA-7 in recipient HO8910PM cells, which eventually reduced the activity of EGFR/AKT/ERK1/2 pathway. Pre-transfection of antagomiR-7 remarkably decreased the levels of miRNA-7 in macrophages, their secreted exosomes and the recipient EOC cells, with the enhancement of HO8910-PM metastasis.  Conclusion · Exosomal miRNA-7 from TWEAK-stimulated macrophages plays a critical role in suppressing the metastasis of EOC cells by attenuation of EGFR signaling

    doi: 10.3969/j.issn.1674-8115.2017.06.004

    Abstract ( 966 )   PDF (8222KB) ( 837 )  

     Objective · To investigate whether vitamin E could reverse the disruptive effects of bisphenol A (BPA) on steroidogenesis and to explore the optimal vitamin E concentration.  Methods · Rat primary granulosa cells were extracted and exposed to BPA (0, 0.01, 0.1,1,10,100 μmol/L). After 48 h of incubation, culture medium was collected and estradiol (E2) and progesterone (P4) were measured using ELISA kits. Then, granulosa cells were incubated with 5 μmol/L(average concentration in follicular fluid) or 25 μmol/L (high concentration in follicular fluid) vitamin E (α-tocopherol) or vitamin E (5 μmol/ L or 25 μmol/L) plus BPA (10 μmol/L or 100 μmol/L) for 48 h, E2 and P4 were measured.  Results · BPA at 10 μmol/L and 100 μmol/L suppressed E2 and P4 production in a dose-dependent manner (P<0.05). Vitamin E at 25 μmol/L significantly increased E2 and P4 levels by (44.89±15.18) % and (43.33±8.82) % (P<0.05), respectively. Coincubation of the granulosa cells with BPA and vitamin E (5 μmol/L or 25 μmol/L) restored the productions of E2 and P4, which were not significantly different from the control group (P>0.05).  Conclusion · Vitamin E (5 μmol/L/ 25 μmol/L) could reverse BPA-induced reduction in steroid hormone production in rat ovary granulosa cells, and the antagonistic effect of 25 μmol/L vitamin E was more obvious than that of 5 μmol/L vitamin E.

    Abstract ( 1025 )   PDF (7961KB) ( 812 )  

     Objective · To identify the effect and potential mechanism of gambogic acid (GA) on natural killer/T-cell lymphoma (NK/TCL) cell lines.  Methods · SNK-1, SNK-6 and SNT-8 were incubated with various concentrations of GA for 24 h, and cell viability was detected with CCK-8 assay. Cell apoptosis was examined by Annexin V-FITC/PI staining assay. Levels of proteins regulating cell apoptosis and phosphorylation levels of proteins in key signaling pathways were detected by Western blotting.  Results · GA showed a potent effect on reduction of cell viability of NK/TCL cell lines in CCK-8 assay. GA increased the percentages of Annexin V positive cells and induced activation of caspase-3 and caspase-9, cleavage of PARP as well as the reduction of Bcl-xl. GA also inhibited the phosphorylation levels of STAT3 in SNK-1 and SNT-8, and ERK1/2 in SNK-1 and SNK-6 significantly.  Conclusion · GA induces cell apoptosis in NK/TCL cell lines SNK-1, SNK-6 and SNT-8. Anti-apoptosis protein Bcl-xl and signaling pathway JAKs/ STATs and MEK/MAPK might be involved in this process.

    Abstract ( 764 )   PDF (11776KB) ( 892 )  

     Objective · To explore the relationship between baseline lipid profiles and long-term cardiovascular outcomes after intervention with hypoglycemic drugs metformin and glipizide and to detect lipid components that can predict the long-term cardiovascular effect of metformin and glipizide.  Methods · Liquid chromatography–quadrupole time of flight–mass spectrometry (LC-QTOF/MS) was used to measure 119 lipid components in baseline serum for 116 patients with type 2 diabetes (T2DM) and atherosclerotic heart disease (CHD) who were treated with glipizide (56 cases, the glipizide group) or metformin (60 cases, the metformin group). Cardiovascular complex end points (including cardiovascular death, all-cause death, nonfatal myocardial infarction, nonfatal stroke, and arterial revascularization) of all patients were followed up. The relationship between lipid components and cardiovascular  complex end points was analyzed with Logistic regression analysis. The category-free net reclassification index (cfNRI) and the integrated discrimination improvement (IDI) were used to evaluate whether lipid components are helpful for predicting the recurrent cardiovascular events.  Results · The differences in baseline drug distribution, clinical characteristics, and biochemical indexes between two groups were not statistically significant, except for diuretics use, serum PC (O-34:2) level, and SM (d18:0-24:0) level. Logistic regression analysis showed that baseline ChE (20:4) was a protective factor for recurrent cardiovascular events in the glipizide group (OR=0.87, P=0.039). ChE (20:4) significantly increased the cfNRI and IDI of cardiovascular  complex end points by 69% and 0.07, respectively (P=0.011, P=0.028). Baseline SM (d18:1-22:0) was a risk factor for recurrent cardiovascular events in the metformin group and all participants (OR=1.65, P=0.039; OR=1.64, P=0.014). SM (d18:1-22:0) significantly increased the cfNRI of cardiovascular  complex end points in the metformin group and all participants by 74% and 55%, respectively (P=0.012, P=0.005).  Conclusion · Of 119 lipid components measured with LC-QTOF/ MS, baseline ChE (20:4) is a protective factor and SM (d18:1-22:0) is a risk factor for cardiovascular  complex end points in with T2DM and CHD patients after long-term treatment with metformin and glipizide. Both lipid components are helpful for improving the prediction of recurrent cardiovascular events.

    Abstract ( 971 )   PDF (7749KB) ( 761 )  

     Objective · To explore influencing factors associated with the hydration status in peritoneal dialysis (PD) patients.  Methods · Eligible PD patients treated in Renji Hospital affiliated to Shanghai Jiao Tong University School of Medicine from September 2016 to January 2017 were enrolled. Demographic data of patients were collected and biochemical indexes were measured. Their peritoneal transport characteristics and dialysis adequacy were evaluated. Hydration status index overhydration (OH) value was measured with bioimpedance spectroscopy. Multivariate linear regression was used to analyze the independent factors associated with the OH.  Results · A total of 147 PD patients with a median age of 58.52 years and a median PD duration of 43.03 months were enrolled. Of them, 90 (61.2%) were male, 21(14.3%) were accompanied by diabetes mellitus, and 107 (72.8%) were overhydrated (OH>1.1L). Compared to those with normal hydration status (OH ≤ 1.1 L), the overhydrated patients had higher proportion of diabetes,
     BSA, Charlson comorbidity score, brain natriuretic peptide (BNP), 4 h D/Pcr, and 24 h dialysate protein, and lower tKt/V, serum albumin than the normal hydrated patients (all P<0.05). Multivariate linear regression showed that comorbid diabetes mellitus (P=0.000), higher 4h D/Pcr (P=0.000), and lower serum albumin level (P=0.001) were independent relevant factors for the increase of OH.  Conclusion · Overhydration is common in PD patients. Comorbid diabetes mellitus, higher 4 h D/Pcr, and lower serum albumin are independent relevant factors for the hydration status in
     PD patients.

    Objective · To investigate the prospective value of early postoperative PI-APD in children with hydronephrosis.  Methods · Data of children with hydronephrosis who underwent pyeloplasty in Xinhua Hospital, Shanghai Jiao Tong University School of Medicine between Jan 2012 to Nov 2015 was collected. PI-APD was divided into 3 categories ( ≤ 19%, 19%<PI-APD<40% and ≥ 40%). The relationship between PI-APD value and the degree of renal function (DRF) and dilation recovery after surgery was analyzed.  Results · There were 360 children with hydronephrosis. The median follow-up was 20 months. The PI-APD value (3 months after pyeloplasty) was positively correlated with the degree of DRF recovery (r=0.631, P=0.000). Five patients received redo-pyeloplasty. PI-APD of all these patients was <19%.  Conclusion · PI-APD is a new feasible ultrasound parameter in pyeloplasty followup. PI-APD ≥ 40% at the first post-operative visit predicts pyeloplasty success. PI-APD ≤ 19% indicates close follow-up after operation. PI-APD can also help select children at high risk for repeat intervention after pyeloplasty.

    Abstract ( 719 )   PDF (8645KB) ( 847 )  

    Objective · To evaluate the safety of neoadjuvant therapy which was constituted by docetaxel based systemic chemotherapy and maximal androgen blockage for patients with locally advanced prostate cancer and to summarize the related adverse events and clinical managements.  Methods · From June 2015 to February 2017, the clinical data of 55 patients undergoing neoadjuvant chemotherapy combined with complete androgen deprivation were retrospectively reviewed. The patients were given docetaxel and prednisone as DP regimen every 3 weeks and LHRH analogues with bicalutamide as maximal androgen deprivation for a total of 4 cycles. All treatment-related adverse events were observed and then recorded.  Results · Two cases with liver function impairment after 2 cycles of treatment were withdrawn from the study. No severe allergic reactions occurred during neoadjuvant therapy. The most common adverse events were hematologic toxicity, while 23.6% of patients had grade III-IV neutropenia, and about 12.7% had anemia. Due to a relatively short course of treatment, the skin or mucous damage, peripheral neurotoxicity and fluid retention were rare. However, hot flash, male breast development as well as erectile dysfunction were very frequently observed due to maximal androgen deprivation. The majority of these adverse events were relieved by symptomatic and supportive treatment.  Conclusion · After strict selection, 4 cycles of neoadjuvant chemotherapy combined with total androgen blockade could be well tolerated by the patients with high-risk locally advanced prostate cancer. Even though the adverse events were controllable, they still need to be closely monitored during treatment in order to reduce the incidence. In addition, the very low testosterone level associated endocrinal metabolic disorders caused by complete androgen deprivation were also of great concern.

     Objective · To compare the impacts on clinical efficiency and safety between 0.014 inch Synchro microwire and Transend microwire used during mechanical thrombectomy for acute ischemic stroke (AIS) caused by large artery occlusion.  Methods · Forty-six patients undergoing mechanical thrombectomy with stent retrievers between October 2012 and January 2016 were included, who were classified into Synchro group (21 cases) and Transend group (25 cases). The clinical outcome, procedure time, and safety were analyzed and compared between two groups.  Results · The recanalization rates were similar between two groups (P=0.600) , but time from puncture to vascular recanalization of Synchro group was much shorter than that of Transend goup (48.88 min vs 82.33 min, P=0.001). The rates of functional independence (modified Rankin scale score ≤ 2) were similar between two groups (P=1.000). There was no significant difference of the rates of post-procedure subarachnoid hemorrhage (PSAH) between two groups (P=1.000). However, there were two cases that had fatal subarachnoid hemorrhage with intracranial hematoma in Transend group, while there was only one case of mild subarachnoid hemorrhage who recovered well in Synchro group.  Conclusion · Compared with Transend microwire, Synchro microwire can significantly shorten the procedure time of mechanical thrombectomy, and the risk of fatal subarachnoid hemorrhage is rather small.

    doi: 10.3969/j.issn.1674-8115.2017.06.020

    Abstract ( 1555 )   PDF (9758KB) ( 1056 )  

    The remodeling and reparative process post myocardial infarction (MI) can be divided into three phases: the inflammatory phase, the proliferative phase and the stable phase. The inflammatory immune response plays an important part in the process of cardiac remodeling. First of all, the initiation of inflammatory response relies on the activation of innate immunity with a group of pro-inflammatory cytokines, chemokines and adhesion molecules. These molecules lead to the infiltration of the infarct area with neutrophils and mononuclear cells, further clearing the wound from dead cardiomyocytes and matrix debris. After resolution of inflammatory response, reparative cells and cytokines infiltrate into the heart and promote the differentiation and growth of myofibroblasts and endothelial cells, contributing to wound contraction as well as producing fiber tissue to form a scar. Moreover, overactive immune responses could accentuate infarct injury and dilative remodeling while deficiency of inflammation leads to insufficient repair, which highlights the dual function of the immune response in myocardial injury and repair post MI. Also the intense immune response along with fibrosis in non-infarct area is also closely associated with adverse remodeling. Thus, targeting specific factors in the inflammatory reaction may hold promise in patients with MI.

    Titanium and titanium alloys, which are bio-inert materials and have excellent mechanical properties, have broad applications in clinic.On the one hand, TiO2 nanotube can effectively enhance the osteogenic differentiation of bone marrow mesenchymal stem cells and have antimicrobial abilities in some extent; On the other hand, TiO2 nanotube, an outstanding drug-carrier, could effectively prevent and treat bone implant-related infection by loading antimicrobial agents. By means of modifying the nanotube coating, improving the efficiency of drug loading and ameliorating release profile, the ideal antimicrobial property could be achieved. Strategies for drug release can be divided into two approaches, namely mechanical release and intellectual release. Mechanical release could fortify the antibacterial ability of coating, but the unicity and uncontrollability of agents diluting need to be resolved. By contrast, intellectual agents release has the advantages of multiple drug species, controllable release volume and programmed trigger condition. This article reviews the current and potential methods of antibacterial substances loading and release from TiO2 nanotube, and expects to provide the orientation for future direction of controllable and intellectual nanotube drug release.

    Abstract ( 775 )   PDF (9416KB) ( 966 )  

    As one of important B vitamins, folate is an essential nutrient for the body and involves in various biochemical and metabolic reactions. Studies have shown that as an important methyl donor in the carbon metabolism cycle, folate has an important impact on pregnancy, pregnancy complications, and birth defects. Further studies have shown that in the folate metabolic pathway, the gene polymorphism and folic acid metabolism of a key enzyme, 5,10- methylenetetetrahydrofolate reductase (MTHFR), play an important role in ovarian function. Gene polymorphism and the high homocysteine levels caused by it can lead to the damage of reproductive function and endocrine function, including follicular development, embryonic development, and hormone secretion. Gene polymorphism is also associated with the occurrence and development of ovarian disease and its response to treatment. With the deep understanding of folate metabolism, MTHFR gene polymorphism may become a new genetic marker for predicting the risk of disease and a new target for related gene therapies
