1.Research Progress of Pathogenesis of Atherosclerosis
Journal of Applied Clinical Pediatrics 1986;0(01):-
Atherosclerosis(AS)is a chronic inflammatory disease of arteries,induced by the injury of endothelial cells,accumulation of mononuclear macrophage and lipid,proliferation of smooth muscle cells and the adhesion of platelets.As a frequent disease and a common pathology in cardiovascular system.In fact,the inciting event of AS is likely an inflammatory insult that occurs decades before the disease becomes clinically apparent.More and more cases were also reported in the childhood recently.Therefore it is important both for clinic and research to investigate the cause and pathogenesis of AS.J Appl Clin Pediatr,2009,24(1):58-60

OBJECTIVETo study the effect of Compound Ezhu Powder (CEP) on serum levels of CA125 and CA19-9, and the expression of cyclin D protein in endometriosis patients, thus providing theoretical evidence for clinical application of CEP.
METHODSTotally 69 all endometriosis patients underwent surgical treatment at Department of Gynecology and Obstetrics, Tianjin Nankai Hospital from January 2011 to January 2013 were randomly assigned to group A (35 cases) and group B (34 cases). Meanwhile, 30 patients with uterine fibroids who prepared for surgical treatment during the same period were recruited as the control group. Patients in group A took EZP 3 months before surgery. No treatment was given to patients in group B and the control group. The serum CA125 level and the expression of cyclin D in the ectopic endometrium and the eutopic endometrium were detected in the 3 groups before surgery.
RESULTSThe expression of cyclin D was higher in group A and group B than in the control group (P < 0.05). The serum levels of CA125 and CA19-9 were significantly lower in group A than in group B (P < 0.05). The expression of cyclin D in the ectopic endometrium was lower in group A than in group B, but with no statistical difference (P > 0.05). The expression of cyclin D in the eutopic endometrium was significantly lower in group A than in group B with statistical difference (P < 0.05). Meanwhile, the serum CA125 level was positively correlated with the serum CA19-9 level (r = 0.45, P < 0.05).
CONCLUSIONSThe expression of cyclin D obviously increased in endometriosis patients, which was associated with the occurrence of endometriosis. CEP could lower serum levels of CA125 and CA19-9, and down-regulate the expression level of cyclin D, indicating its roles in inhibiting the cell cycle.

BACKGROUND: Studies have demonstrated that hyperpolarization-activated andcyclic nucleotide-gated cation channels (HCN) 2 and HCN4 are abnormal expressed in ventricular muscle following heart disease, which is closely correlate to ventricular arrhythmia. Bone marrow stem cells (BMSCs) transplantation can improve damaged cardiac muscle; however, its effect on remodeling of ion channel is unclearly. OBJECTIVE: To detect the changes of HCN2 and HCN4 expression in left ventricle following BMSCs transplantation.METHODS: Five Sprague-Dawley (SD) rats, aged 3 weeks, were prepared for BMSCs by Percoll method. Additional 30 health, male, SD rats, were randomly divided into DMEM, cell transplantation, sham operation and control groups. At 4 weeks after model preparation, DMEM culture medium was injected into the infarcted area and surroundings with 5 points in the DMEM group. The 3rd generation of cultured BMSCs (200 μL, with 5×10~6 cells) were injected into rats in the cell transplantation group with the same methods. The mRNA and protein expression of HCN2 and HCN4 gene was detected by RT-PCR and Western blot respectively.RESULTS AND CONCLUSION: In non-infarcted region, the mRNA and protein expression of HCN2 and HCN4 among each groups had no significant difference (P > 0.05). Compared with the control and sham operation groups, mRNA and protein expression of HCN2 and HCN4 in surrounding of the infracted region was elevated in the DMEM group (P < 0.05), which was greater than that of the cell transplantation group (P < 0.05). The mRNA and protein expression of HCN2 and HCN4 was smaller in the center area of infracted region in the DMEM group than that of the control and sham operation groups (P < 0.05), which was similar to the cell transplantation group (P > 0.05). Acute myocardial infarction can increase mRNA and protein expression of HCN2 and HCN4 in infracted region surrounding. BMSCs transplantation may lower the fatality rate of ventricular arrhythmia by reducing HCN2 and HCN4 expression.

Aim To evaluate the effects of aspirin on the expression of inflammatory proteins induced by oxidized low-density lipoprotein(ox-LDL) in human vascular endothelial cells (HUVECs). Methods HUVECs were stimulated with different concentrations of ox-LDL. The expression of inflammatory proteins was detected by Western blot.Intracellular ROS generation was measured by flow cytometry using perexide-sensitive flurscent probe 2′, 7′-dichrofluorescein diacetate(DCFH-DA).Results ① Aspirin inhibited COX-2 expression induced by ox-LDL. Cells were preincubated with 2.5 mmol?L-1, 5 mmol?L-1 of aspirin or without any treatment for 30 min and then stimulated by 0.3 g?L-1 ox-LDL for 16 h, COX-2 expression was reduced by treating of aspirin.COX-2 expression was enhanced after the stimulation with ox-LDL, and aspirin inhibited the increasing.② Aspirin suppressed ICAM-1 expression induced by ox-LDL in HUVECs. ICAM-1 expression was increased by ox-LDL stimulation for 16 h, and aspirin significantly down-regulated the expression. Similar results were obtained by immunofluorescence.③ Aspirin partially reduced ROS production induced by ox-LDL in HUVECs. After stimulation with 0.3 g?L-1 ox-LDL for 16 h, the intracellular level of ROS was increased, however, aspirin failed to fully inhibit the phenomenon.Conclusion Nonsteroidal anti-inflammatory drugs (NSAID) aspirin significantly down-regulated the expression of COX-2 and ICAM-1 induced by ox-LDL.The results suggested that aspirin could reduce the inflammation responses mediated by ox-LDL on HUVECs in atherosclerosis.

?AIM:To investigate the measurement of central anterior chamber depth ( ACD ) in patients with acute primary angle - closure glaucoma ( APACG ) with A - scan ultrasound, Pentacam and ultrasonic biological microscope ( UBM) .?METHODS: Thirty-five patients (35 eyes) with APACG were selected, of whom central ACD were measured with A-scan ultrasound, Pentacam and UBM.?RESULTS: The measurement values of ACD with A-scan ultrasound, UBM and Pentacam were 1. 5633±0. 2089, 1. 5783 ± 0. 2067, 1. 6275 ± 0. 2296mm, which was equal variance tested by the homogeneity of variance, and was significant different by multiple comparision (F=4. 074, P=0. 026). The difference of ACD between the two groups of A-scan ultrasound and UBM, A-scan ultrasound and Pentacam, UBM and Pentacam were statistically significant ( P = 0. 032, 0. 023, 0. 012 ). Altman- Bland analysis showed that the three methods were not consistent with each other.?CONCLUSION: The ACD value of the APACG with the three methods is the largest using Pentacam, followed by UBM and A - scan ultrasound. In clinical the three methods with different advantages can complement each other, but cannot be replaced. In order to obtain more accurate results, we should combine the advantage and make comprehensive analysis.
