1.Advances in prevention and treatment on inflammation and myocardial ischemia-reperfusion injury by PPAR-? ligands
Chinese Journal of Pathophysiology 1986;0(01):-
Peroxisome proliferation-activated receptor-? (PPAR-?) is a ligand-activated transcription factor belonging to the nuclear hormone receptor superfamily and participates in the regulation of various metabolic pathways as well as inflammatory responses. PPAR-? ligands significantly improve myocardial functional recovery and prevent ischemia-reperfusion induced injury. Given the increasing understanding of the cardioprotective effects of PPAR-? ligands,we know today that the therapeutic effects of PPAR-? ligands reach far beyond their use as insulin-sensitizers,as many of these agents exert beneficial effects in the conditions associated with ischemia-reperfusion and inflammation.

Objective To investigate the functions of Monocyte chemotactic protein-induced protein 1 (MCPIP1) in human breast cancer cell line MDA-MB-231.Methods MDA-MB-231 cells were transfected with GFP-tagged MCPIP1 by Tet-on inducing expression system.Endogenous MCPIP1 was knocked down by stable expressing shRNA.MTT assay was performed to measure the growth of MDA-MB-231 cells after overexpression or knockdown of MCPIP1.FACS method was used to analyze cell cycle in MDA-MB-231 cells.Real-time PCR was used to test the expression of cell cycle-related mRNAs expression and their half-lives.RNA-IP experiment was conducted to detect the mRNA directly enriched by MCPIP1.Luciferase assay was performed to determine whether the mRNA decay was mediated through 3′UTR.Results MCPIP1 overexpression significantly inhibited cell proliferation(P<0.05), while knockdown MCPIP1 promoted cell proliferation with statistical significances (P<0.05).MCPIP1 induced cell cycle arrest in MDA-MB-231 with statistical significance (P<0.01).MCPIP1 overexpression reduced the half-lives of cell cycle mRNAs (CDK2,CDK6,cyclin D1,cyclin E1,respectively) with significance (P<0.01).In addition, cell cycle-related mRNAs were able to be pulled down by GFP-MCPIP1 but not isotype IgG(P<0.05).Compared with control vector, MCPIP1 significant suppressed luciferase activities of all four 3′UTR reporters (P<0.05).Conclusions MCPIP1 functions as a tumor suppressor in human breast cancer cell line MDA-MB-231 through inducing G1 cell cycle arrest.

Objective To investigate diagnostic and prognostic significance of protein C in acute leukemia with disseminated intravaseular coagnlation(DIC). Methods APTT, P-T, D-Dimer, Fbg, antithrombin (AT) and protein C(PC) were determinated in plasma of 44 DIC patients with acute leukemia and 30 normal controls. Results PC was markedly lower in disseminated intravaseular coagulation with acute leukemia group(67.03±36.98) than that of control group (99.53±45.20), and significantly correlation DIC score( r = -0.57,P<0.01). PC of abnormality rate in DIC group was 86.36 %. APTT, PT, D-Dimer, Fbg were significantly increased and AT was decreased during the progress of DIC in relation to values observed in the control group. Conclusion DIC is related to the disorder of coagulation and fibfinolysis system. PC is a sensitive index to diagnose and prognose DIC in acute leukemia.

Objective To explore the method of primary isolation, cultivation and identification of rat brain microvessel pericytes. Methods The brain tissue of 10 3 week-old Wistar rats was separated sterilely. The brain microvessel fragments were separated using two-step enzyme digestion and one-step gradient centrifugation and were seeded in 35-mm dishes for primary culture. The cell morphology was observed by phase contrast microscopy; the immunofluorescence assay was used to identify the associated antigns, such as the α-smooth muscle actin (α-SMA), neuron-glial antigen 2 (NG2), von Willebrand factor (vWF), and glial fibrillary acidic protein (GFAP). Methyl thiazolyl tetrazolium was used to determine the cell growth curve. Results Pericytes climbed out from the adherent brain microvascular fragments around,showing polygonal, and the cell fusion was 95% after 12-14 days. Immunofluorescence staining revealed that the molecular markers of the pericytes α-SMA and NG2 related antigens showed double positive, while the vWF and GFAP related antigens showed double negative and the cultured cells were confirmed as brain microvascular pericytes. The growth rate of primary cells was slower. The passage cells entered into logarithmic growth phase after 36 to 60 hours and entered into plateau phase after 72 to 108 hours. Conclusions This method may successfully isolate rat brain microvascular pericytes with higher purity.

OBJECTIVE:
To evaluate the physical and mental health status of post-linguistic cochlear implantees, and then to explore the effectiveness on of different rehabilitation programs.
METHOD:
Mandarin hearing in noise test (MHINT), personal report of communication apprehension (PRCA-24) and Nijmegen cochlear implant questionnaire (NCIQ) were used to measure the hearing ability, mental health degree and the health related life quality in 36 post-linguistic cochlear implant users, respectively. The improvement of subjects' physical and mental health levels was compared with among different rehabilitation programs, including family training program, auditory habilitation program and psychological intervention program.
RESULT:
(1) Family training program only can improve the subject's hearing ability (P < 0.05), but failed to ease the communication apprehension; ((2) Auditory habilitation program can both significantly improve the subjects' hearing ability (P < 0.01) and ease the fear of talking face to face (P < 0.01); (3) Psychological intervention program can significantly increase the auditory abilities (P < 0.01), reduce the communication apprehension (P < 0.01) and improve the quality of life.
CONCLUSION
Post-linguistic cochlear implantees had obvious mental symptoms. It was very important to design an effective rehabilitation program to improvement the living quality of hearing loss people.
