The 3T road map proposed by Dougherty and Conway views translational research as a continuous process that moves from basic research through clinical (T1),postclinical (T2),and practice-based research and ultimately to health policies,outcomes,and impacts (T3).It can be used as a fundamental framework for evaluating and measuring translational research.The citation networks between publications may reveal translational interfaces,translational path,and translational lag in a specific research field,which can help researchers understand the critical content and road maps during their translational research,and thus accelerate translational medicine during T1,T2,and T3 phases of translational research.Based on the citation networks,we built a two-dimensional model for measuring the process of translational research.

Objective The study was to investigate the relationship among angiotensin 1-converting enzyme(ACE), plasminogen activator inhibitor-1 (PAI-1)gene polymorphisms and the common carotid artery (CCA-IMT), and the predicting effects of them on CCA-IMT in newly diagnosed type 2 diabetes (T2DM). Methods The polymorphisms of ACE (I/D) gene and PAI-I (4G/5G) gene were deter-mined by polymemse chain reaction-restriction fragment length polymorphism (PCR-RFLP) and allele-specific polymerase chain reaction (AS-PCR) method in 308 cases with T2DM. CCA-IMT was compared among the groups with different genotypes of ACE and PAI-1. The in-dependent or synergistic effects of the ACE I/D and PAI-1 40/5G polymorphisms on CCA-IMT in 308 patients with T2DM were analyzed with multivariate linear regression. Then the 156 newly diagnosed type 2 diabetics (durations< I year) without AS received the maltifactorial targeted intervention, including taking aspirin and controlling blood glucose, blood pressure, blood lipid and body weight. The differences of metabolic control, ACE (I/D) and PAId (40/5G) gene polymorphisms were analyzed. Logistic regression analysis was used to analyze the eorrelation among the CCA-IMT, ACE (I/D) and PAI-1 (4G/5G) polymorphisms. Results Patients with ACE DD genotypes had higher CCA-IMT than those with ACE-Ⅱ or ACE ID genotypes. Patients with both ACE DD and PAI-1 404G genotypes had a higher CCA-IMT than those with any other pairs of genotypes. Multivariate linear regression analysis showed that ACE DD and PAI-1 4G4G gene polymorphisms had synergistic effect on the CCA-IMT in T2DM patients. After 2 years multifactorial intervention, the frequencies of PAI-1 4G alleles and 404G genotypas were lower than those in the CCA-IMT non-inereasing group. Conclusions These findings indicate that the ACE-DD geno-type and its synergistic effects with the PAI-1 4G/4G genotype are independent risk factors for the CCA-IMT in T2DM patients. Under multi-factorial intervention for 2 years, PAI-1 4G/4G genotype may be a negative predictor for the progression of CCA-IMT in T2DM patients.

The real-time monitoring of cerebral hemorrhage can reduce its disability and fatality rates greatly. On the basis of magnetic induction phase shift, we in this study used filter and amplifier hardware module, NI-PXI data-acquisition system and LabVIEW software to set up an experiment system. We used Band-pass sample method and correlation phase demodulation algorithm in the system. In order to test and evaluate the performance of the system, we carried out saline simulation experiments of brain hemorrhage. We also carried out rabbit cerebral hemorrhage experiments. The results of both saline simulation and animal experiments suggested that our monitoring system had a high phase detection precision, and it needed only about 0.030 4s to finish a single phase shift measurement, and the change of phase shift was directly proportional to the volume of saline or blood. The experimental results were consistent with theory. As a result, this system has the ability of real-time monitoring the progression of cerebral hemorrhage precisely, with many distinguished features, such as low cost, high phase detection precision, high sensitivity of response so that it has showed a good application prospect.

Objective To present our experience with management of craniopharyngiomas by endoscopic endonasal approach Methods A retrospective review of clinical data of 65 patients who were treated for craniopharyngiomas by endoscopic endonasal approach from February 2012 to May 2016. All patients were analyzed by treatment effect, complications, and follow-up result. Results Total removal of the tumors were completed in 52 cases (80.0%), subtotal removal in 11 cases (16.9%), and partial resection in 2 cases (3.1%). The pituitary stalks were identified in 57 cases when surgery, and severed in 41 cases (71.9%). Postoperative visual acuity was improved in 31 cases (47.7%), and 6 cases remained in the preoperative level, whereas worsening occurred in 1 case. Worsening of the anterior pituitary function was reported in 21 cases (32.3%). Transient diabetes insipidus after operation was occurred in 45 patients (69.2%), and long-term diabetes insipidus was occurred in 9 cases (13.8%). Postoperative cerebrospinal fluid (CSF) leak was occurred in 4 cases (6.2%), accompanied with intracranial infection, and all these cases were repaired under endoscope again, 3 cases were saved, but 1 case was dead. Perioperative mortality rate was 4.6%. 52 patients were followed up for 4.0 ~ 45.0 (mean, 20.8) months, and 44 patients (84.6%) returned life to normal. Obesity developed in 8 patients (15.4%), with 2 recurrent cases and no deaths during follow-up period. Conclusion The endoscopic endonasal approach is a safe and effective minimally invasive surgery approach for treating craniopharyngiomas, and has its own unique advantage.

ObjectiveTo explore the effect of estrogen on osteoblast apoptosis induced by serum hungry in vitro.MethodsOsteoblasts of second or third generation from newly born SD rats calvaria were divided randomly into the control group, serum hungry group and serum hungry with estrogen group. Cells of each group were incubated for 24 h, 48 h, 72 h, 5 d, 7 d and 14 d, then labeled using TUNEL staining and examined for morphological characteristics of apoptotic cell under light microscopy after incubated for 72 h. The rates of apoptotic cells of each group were examined with flow cytometry.ResultsThe cells of the control group showed normal appears, the serum hungry group had many cells with purple and blue particles in nuclei, but serum hungry with estrogen group had less such cells. The rate of apoptotic cell significantly increased in serum hungry group and decreased in serum hungry with estrogen group compared with the control group examined with flow cytometry (P<0.05).ConclusionEstrogen can repress osteoblasts apoptosis of rats induced by serum hungry.
