3.Biological effects of hypoxia on mesenchymal stem cell
International Journal of Biomedical Engineering 2013;36(3):184-188
Mesenchymal stem cell (MSC) resides in a relatively hypoxia niche (volume fraction 1%~7%)compared to normoxia (20%).MSC cultured in hypoxia condition shows different biological features from those in normoxia condition.Hypoxia inducible factor-1 α (HIF-1 α),as one of main transcription factors in hypoxia,participates in the regulation of cell proliferation,differentiation,apoptosis,glycolysis and angiogenesis.Recent researches show that HIF-lα also plays an important role in regulating the survival,differentiation and migration of MSC.It turns out that hypoxia can improve survival and migration of MSC,enhance chondrogenesis but inhibit adipogenesis through HIF-lα and its downstream genes.However,whether hypoxia promotes or impedes osteogenesis remains controversial.Such differences can be caused by variances of tissue origination,oxygen concentration and culture condition.The comparison of different researches should be based on the same experiment condition.This review focuses on the influence of hypoxia on proliferation,apoptosis,differentiation and migration of MSC.
4.β-Cyclodextrin-cross-linked Polymer Coupled Ultraviolet-Visble Spectrophotometry for Separation and Analysis of p-Nitrophenol
Chinese Journal of Analytical Chemistry 2009;37(11):1691-1694
The β-cyclodextrin cross-linked polymer(β-CDCP) was used as adsorbent to pre-concentrate/separate the trace p-nitrophenol and then the determination was carried by UV-Vis spectrophotometry. Under alkaline condition,the adsorption/elution behavior of p-nitrophenol was studied. In 0. 02 mol/L NaOH solution and at room temperature for 30 min,the resin could separate and pre-concentrate the p-nitrophenol effectively. Methanol solution(1:1,V/V) was used as eluent and the β-CDCP could be used repeatedly. The linear range and detection limit was 0.5 -90.0 mg/L and 3. 10 μg/L,respectively. The proposed method has been used to determine the p-nitrophenol in synthesized sample with satisfactory results.
5.Advancement and perspective of NF-κB in the research of acute pancreatitis
International Journal of Surgery 2010;37(9):621-624
Acute pancreatitis is acute inflammation due to autodigestion of pancreatic tissue by trypsogen activation, can induce systemic inflammatory reaction,and deteriorate to be nonfunction and fatality. Nuclear factor kappa B seizes the coral position in the development of acute pancreatitis, regulates gene expression of inflammatory factors and immune protein. This article reviews the therapy of pancreatitis on account of NF-κB.
6.Multi-scale Permutation Entropy and Its Applications in the Identification of Seizures.
Journal of Biomedical Engineering 2015;32(4):751-756
The electroencephalogram (EEG) has proved to be a valuable tool in the study of comprehensive conditions whose effects are manifest in the electrical brain activity, and epilepsy is one of such conditions. In the study, multiscale permutation entropy (MPE) was proposed to describe dynamical characteristics of EEG recordings from epilepsy and healthy subjects, then all the characteristic parameters were forwarded into a support vector machine (SVM) for classification. The classification accuracies of the MPE with SVM were evaluated by a series of experiments. It is indicated that the dynamical characteristics of EEG data with MPE could identify the differences among healthy, interictal and ictal states, and there was a reduction of MPE of EEG from the healthy and interictal state to the ictal state. Experimental results demonstrated that average classification accuracy was 100% by using the MPE as a feature to characterize the healthy and seizure, while 99. 58% accuracy was obtained to distinguish the seizure-free and seizure EEG. In addition, the single-scale permutation entropy (PE) at scales 1-5 was put into the SVM for classification at the same time for comparative analysis. The simulation results demonstrated that the proposed method could be a very powerful algorithm for seizure prediction and could have much better performance than the methods hased on single sale PF

Objective To understand the clinical characteristics of patients with advanced schistosomiasis in Yingcheng City,so as to provide evidences for the assistance work of advanced schistosomiasis. Methods The clinical data of all the ad?vanced schistosomiasis patients in Yingcheng City were collected and analyzed. Results Up to December 30,2014,there were 96 advanced schistosomiasis patients in Yingcheng City,among which,68 cases(70.8%)were male,28 cases(29.2%) were female,and their average age was 64.2 years. Most of the patients(90.6%)were ascitic type,followed by splenomegaly type(5.2%),colon proliferation type(2.1%),and dwarf type(2.1%). Totally 48 cases(50.0%)were positive in immunologi?cal detections,among which 8 cases(8.3%)were positive in ELISA and 12 cases(12.5%)were positive in IHA. For all the 4 indexes of hepatic fibrosis(HA,LN,CIV and PCⅢ),only 15 cases(15.6%)were normal. Conclusions Though Yingcheng City has reached the criteria of transmission control,the hepatic fibrosis of some patients continues to progress. Therefore,the intensity of the treatment and assistance could not be weakened,especially for those of the ascitic type patients.
