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

Prostate cancer is one of the common malignant tumors of the urinary system and mostly found in elderly men. Like most tumors, prostate cancer involves a variety of molecules in its occurrence and progression. More studies on the development of prostate cancer focus on the tumor markers, DNA damage repair related genes, and tumor invasion and metastasis related factors. This article presents an overview on the research progress in these three aspects.

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.

The total protein of Toxoplasma gondii RH strain tachyzoites was separated by two-dimensional electrophoresis (2-DE), and Western blotting was performed to find out distinct antigens. 209 spots were detected through Coomassie brilliant blue-stained small gels (7?8 cm, pH 3-10). Western blotting showed 17 specific antigen spots with sera of the experimental group and two nonspecific spots with the control sera.

Objective:To evaluate the role of using the double body position CT(DBP-CT)in the staging of advanced gastric cancer.Methods:We performed CT examination in 85 patients with advanced gastric cancer which were divided into the double postion group(55 cases)and the single position group(30 cases),after oral intake water agent.The preoperative CT findings of each group was compared with surgical findings respectively and the accuracy in the CT staging of advanced gastric cancer of each group was estimated.Results:The accuracy in the preoperative CT staging of double position group was 89.09%,and in single postition group was 60%.There was a significant difference(P＜0.05).Conclusion:Our findings show that the DBP-CT is surperior to the single position group in finding lesion,confineing the range of the tumour,and determing the degree of adjacent invasion.It can improve the diagnostic accuracy in the preoperative staging of advanced gastric cancers significantly.

Objective To evaluate the role of different kinds of body positon in the stomach CT scanning.Methods It included 30 normal adults who underwent CT scanning in four differnent kinds of body positions.The relationship between the body position and the image appearence in the each part of stomach has been analysed.Results The results showed that the adjusting of body position was useul in revealing gastric wall and perigastric organs.The best imaging result of fundus ventriculi part of stomach can be obtained with the head down and the feet high position while patients lie on his back.The best body position to reveal corpus ventriculi part is in prone position and the best body position to reveal pars pylorica part is in right lateral position.There is a very significant difference between supine position and the best revealing position of each part of stomach prespectively(?

?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.

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.

Objective We summarized the clinical experience of modified ileal ureter substitution for treating long segment ureteral defection.Methods We retrospectively analyze the clinical data of 2 patients with long segment ureteral defect who treated with Yang-Monti ileal ureter substitution between March 2015 and November 2015.One 75 years old male patient was diagnosed as upper ureteral malignance and solitary kidney.The length of defection from renal pelvis to bladder was 22 em.His serum creatinine was 100 μmol/L,blood urea nitrogen was 5.7 mmol/L,serum chloride was 98 mmol/L.Another one 41 years old female patient was diagnosed as middle and lower ureteral iatrogenic injury.The traumatic length was 15 cm.Her serum creatinine was 70 μmol/L,blood urea nitrogen was 5.1 mmol/L,serum chloride was 100 mmol/L.they were both treated by Yang-Monti ileal ureter substitution.The ileal intestinal segment was used for the ureteral replacement,which were more than 15 cm to the ilealcecum.The length of intestine was 10.0 cm and 7.5 cm,respectively.The ileal mesentery was preserved.After closing the mesangial hiatus,the ileal segment was pull into the retroperitoneal space and pulling out via descending colonic mesangial window.The ileal segment was divided into three parts,which was 2.5 to 3.0 cm in each part.Each part was opened via long axis and then rotated 90 degree.The 4-0 absorable suture was used to suture the edge of each intestinal part continuously.The sutured intestine was re-tubularized,using 4-0 absorable suture and the F16 catheter was used as the tube model.The length of reconstructed ureter was 22 cm and 18 cm,respectively.The neo-ureter was re-anastomosed with renal pelvis and bladder wall.Two F6 double J stents were placed in the neo-ureter.Results The operative time was 160 min and blood loss was 200 ml in the first case.In the second case,the operative time was 180 min and blood loss was 220 ml.No significant complications were noticed intra-operation and post-operation.Six months after operation,the male patient's serum creatinine was 112 pmol/L,blood urea nitrogen was 6.1 mmol/L,serum chloride was 106.0 mmol/L and electrolytes were normal.In another patient,serum creatinine was 79 μmol/L,blood urea nitrogen was 5.9 mmol/L and serum chloride was 103.0 mmol/L.The GFR was 24.9 ml/min and 22.1 m]/min 3 and 6 months after operation,respectively.Ureteral obstruction wasn't detected on IVU images 3 months after operation.Conclusions For patient with long ureteral defect,which cannot be replaced by other urinary tissue,YangMonti ileal ureter substitution is one of the optional modalities.As a new technique of ureteral substitution,Yang-Monti ileal ureter substitution is simple and fewer complications and can improve the quality of life in patient compared with traditional ureteral substitution.

Objective To analyze the clinical and laboratory results and epidemiological characteristics of brucellosis.Methods The clinical and laboratory characteristics brucellosis cases (confirmed by Brucellosis Guidelines 2012) at the Department of Infectious Disease of the First Hospital of Jilin University between 2000 and 2016,were retrospectively evaluated.The patients were divided into two groups according to acute and chronic stages.According to the range of lesions,the lesions were divided into two groups,and comparative analysis of data between groups was done.Results The ages of the 607 patients (489 males,118 females) were ranged from 2 to 80 years.Among the 607 patients,570 (93.9％) were diagnosed with acute brucellosis,37 (6.1％) with chronic brucellosis.Focal involvement was found in 418 (68.9％) patients.Among them,382 patients were in acute stage,and the other in chronic phase (36).Acute patients' alanine aminotransferase (ALT) and aspartate transaminase (AST) were higher than those of chronic brucellosis (U/L:47.2 vs 26.7,44.5 vs 24.0,Z =-3.684,-3.754,all P ＜ 0.05).Although the white blood cell count,platelet values,C-reactive protein,and blood sedimentation were higher in patients with focal involvement (x 103/mm3:7.3 vs 5.4,211 vs 176;mg/L:56.0 vs 30.5;mm/h:37 vs 28,Z =-4.407,-2.709,-2.334,-2.137,all P ＜ 0.05),patients without focal involvement had higher ALT and AST (U/L:33.3 vs 53.9,30.2 vs 48.1,Z =-4.102,-3.730,all P ＜ 0.05).Peripheral arthritis was the most common type of osteoarticular involvement in 317 patients with focal involvement,and peripheral arthritis was found to be the most frequently identified in the knee joint,112 patients (35.3％).Totally 80 patients were followed up,the relapse rate was 20.0％ (16/80),2 patients treatment failure,only 1 patient died after 1 month of treatment who was diagnosed neuropathic brucellosis.Conclusions Focal involvement should be investigated in the presence of leucocytosis,and pain of a certain part.
