Objective To investigate the pathogen and inspection methods of the middle-aged women with constipation and evaluate the accuracy and clinical application of imaging to constipation.Methods First colonic transit test were used to 98 cases of middle-aged women who were diagnosed constipation by doctors,then air-barium double contrast examination were applied.Defecation radiography or simulation rectum defecography were used to those who were diagnosed as outlet obstruction.According to the measure target and diagnostic criteria of professor LU,the results were studied.Results 6 cases were abnormal within 8 cases who were inspected by barium enema.14cases were abnormal within 16 cases who were inspected by defecation radiography.Colonic transit test were used to 74 cases and only 6 cases were normal.16 cases were true slow transmission and 20 cases were false slow transmission.52 cases were outlet obstruction.20 volunteers were inspected by suspension barium sulfate and simulation rectum defecography.Conclusions Air-bariun double contrast examination could discover the organic disease and abnormal of rectum.colonic transit test,defecation radiography and simulation rectum defecography were simply and perfect methods to discover the pathogen of constipation.
5.Interhemispheric functional alterations in unilateral temporal lobe epilepsy
Chinese Journal of Nervous and Mental Diseases 2016;42(10):616-622
Objectives To investigate the alterations of homotopic connectivity in unilateral temporal lobe epilepsy (TLE). Methods Resting-state functional MR imaging data were acquired from patients with unilateral temporal lobe epi?lepsy (n=43) [21 left temporal lobe epilepsy(LTLE) and 22 right temporal lobe epilepsy(RTLE)] and normal controls (NC) (n=20). The functional connectivity between any pair of symmetric interhemispheric voxels (i.e., functional homotopy) was measured by voxel-mirrored homotopic connectivity (VMHC). Results Compared with NC group, the LTLE patients showed decreased functional connectivity in the bilateral supplementary motor areas(t=-3.35), middle temporal gyri (t=-3.50), medial frontal gyri(t=-3.20)and inferior parietal lobules(t=-3.66), and increased interhemispheric func?tional connectivity in the bilateral angular gyri(t= 3.03), occipital gyri(t= 4.25) and superior parietal gyri(t= 3.62). Compared with control subjects, RTLE patients exhibited decreased functional connectivity in the bilateral middle tempo?ral gyri(t=-4.26), precentral gyri(t=-3.29), as well as increased interhemispheric functional connectivity between bi?lateral inferior occipital gyri(t=3.22),parahippocampa gyri(t=3.32), cerebellum(t=3.50). Conclusions There are al?terations of the functional synchronization and coordination in the two hemispheres in unilateral TLE patients.
6.Expression and significance of uPAR and VEGF-C in hepatocellular carcinoma
Cancer Research and Clinic 2009;21(1):32-34
Objective To investigate the expression of uPAR and VEGF-C in hepatocellular carcinoma (HCC) and its effect on the biological behavior of HCC. Methods The expression of uPAR and VEGF-C in liver tissue specimen of 33 patients with HCC was detected by immunohistochemical staining. Results The positive expression of uPAR and VEGF-C in HCC tissues was located in cytoplasma of cancer cells. The positive rates of uPAR and VEGF-C were 69.7 %(23/33) and 78.8 %(26/33) respectively in 33 cases of HCC. The expression rates of uPAR and VEGF-C were significantly higher in HCC with metastasis than in HCC without metastasis(P<0.05). But there were not significant correlation between the expression of uPAR or VEGF-C and tumor size, tumor grade, AFP level, hepatic cirrhosis. There was a close correlation between uPAR and VEGF-C in HCC(r=0.676, P<0.01). Conclusion The expression of uPAR and VEGF-C is correlated with metastasis, uPAR and VEGF-C may be signs of aggressive phenotype for evaluating treatment and prognosis of HCC. Examination of these two proteins may be helpful to .judge biological behavior of HCC.
7.Full-range control model of clinical blood use - Establishment and operation
Chinese Journal of Hospital Administration 2010;26(7):518-520
The medical order number of a blood transfusion is used as the matching number in the full range of clinical blood use. A cycle is built ranging from the application for to the implementation of a medical order for blood transfusion. Such measures as repeated blood types verification by two departments, dual-database management of blood type files, and bar coding are called into play to ensure information correctness. These measures can make sure that the correct blood type is transfused to the correct patient and rule out accidents in blood transfusion. Indications for blood products are set up under real-time surveillance, which makes available limited blood products supply to those in need and minimizes waste and abuse of such products. The full-range and real-time management of clinical blood use will confine blood transfusion indications and ensure patients' safety with 100% match ratio.
8.Research on platelet-derived growth factor and diabetic foot
Chinese Journal of Primary Medicine and Pharmacy 2016;23(15):2391-2393
Platelet -derived growth factor (PDGF)is an important factor of promoting cell growth which has a physiological role ranging from DNA synthesis,cell mitosis inducement,promotion on a variety of extracellular matrix accumulation as well as impact on the cell phenotype and growth.Studies showed that PDGF played an important role in growth and proliferation of vascular and nerve.It has a significant effect on accelerating tissue repair and promoting healing of chronic diabetic foot ulcers.
9.Research progress of the diagnosis and treatment of diabetic cardiomyopathy
Chinese Journal of Primary Medicine and Pharmacy 2016;23(11):1748-1750
Objective Diabetic cardiomyopathy is a heart disease that excludes coronary heart disease,hypertensive heart disease and other heart diseases,and patients with diabetes mellitus prone to cardiac structural and functional changes.Echocardiography is often the first choice of examination methods,and nuclear magnetic resonance and nuclear magnetic resonance imaging is a new method to observe the changes of myocardial fibrosis and myocardial metabolism.In the treatment,need to a variety of methods to intervene,such as blood glucose control,using statin lipid -lowering drugs,angiotensin converting enzyme inhibitor,angiotensin receptor blocking agent,beta blockers,antioxidants,and traditional Chinese medicine etc.
10.Construction and effect of recombinant adenovirus vector containing siRNA targeting Raf-1 on cardiomyocyte hypertrophy in neonatal rats
Chinese Journal of Comparative Medicine 2016;26(4):18-23
Objective To construct an adenovirus vector expressing small interfering RNA ( siRNA) targeting to rat Raf-1 gene and identify its function in cardiomyocytes.Methods The siRNA containing DNA sequence targeting to Raf-1 and its negative control sequence were designed, synthesized, annealed and subcloned into adenoviral shuttle vector pAdTrack-CMV.The recombinant adenovirus vector pAd-siRaf-1 was obtained by homologous recombination with pAdTrack-siRaf-1 linearized by PmeI and pAdeasy-1 in bacteria BJ5183, then transfected into HEK293 cells to package the adenovirus.Cardiomyocytes were infected with the adenovirus pAd-siRaf-1, and the expressions of Raf-1 and NF-κB protein were detected by Western blotting.[ 3 H ]-leu incorporation was evaluated by scintillation.The surface area of cardiomyocytes was measured using a HJ2000 image analysis system.Results The adenovirus vectors were verified by enzyme digestion and DNA sequencing.Compared with the Ang II group, Raf-1 and NF-κB expression, the surface area and [ 3 H]-leu incorporation of cardiomyocytes were significantly decreased in cardiomyocytes infected with the adenovirus PAd-siRaf-1.Conclusions A recombinant adenovirus vector containing rat siRaf-1 gene is successfully constructed.It can effectively reduce Raf-1 and NF-κB expression and cardiomyocyte hypertrophy induced by Ang II.
