AIM: To observe activity of scavenger receptor of macrophage derived from monocytes, the change of inflammation factor in plasma (including CRP, sICAM-1, sVCAM-1) and the influence of atorvastatin on activity of scavenger receptor in patients with coronary heart disease. METHODS: 75 patients with coronary heart disease (CHD), whose plasma lipid levels were normal, were divided into three groups: stable angina pectoris, unstable angina pectoris and acute myocardia infarction. 29 healthy persons were served as control. The level of C-reactive protein (CRP), soluble intercellular adhesion molecule-1 (sICAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) in plasma were determined in all subjects. Monocytes in peripheral blood were dissevered and cultured to transform into macrophage. The influence of atorvastatin on activity of scavenger receptor in macrophage was observed. RESULTS: The level of CRP, sICAM-1, sVCAM-1 and activity of scavenger receptor of macrophage in acute myocardia infarction group were higher than that in stable angina pectoris, unstable angina pectoris and control. Atorvastatin lowered the activity of scavenger receptor of macrophages derived from monocytes in patients with coronary heart disease. Activity of scavenger receptor of macrophages derived from monocytes in patients with coronary heart disease was correlated positively with CRP, sICAM-1 and sVCAM-1. CONCLUSION: Activity of scavenger receptor may be taken as index for monitoring the degree of active vulnerable atherosclerosis plaque. Atorvastatin may inhibit activity of scavenger receptor in macrophages derived from monocytes in patients with coronary heart disease.

AIM: To observe the effects of irbesartan and perindopril on pressure-overload cardiac hypertrophy in rats. METHODS: 40 male adult Sprague Dawley rats were divided into 5 groups. One was sham operation group, other four were aortic banding groups. One week after operation, all rats were gavaged with normal saline, perindopril, irbesartan or combination of perindopril and irbesartan. Morphometric determination, calcineurin (CaN) expression, CaN and sarcoplasmic reticulum (SR) Ca 2+-ATPase activity were performed at the end of 6 weeks of drug intervention. RESULTS: Left ventricular mass index (LVMI), transverse diameter of myocardical cell (TDM), CaN activity were remarkably decreased after drug intervention and this decrease was most remarkable in the combination group. SR Ca 2+-ATPase activity increased after drug intervention, especially in the combination group. CaN expression in myocardium were remarkably decreased after drug intervention. LVMI was positively correlated with TDM and CaN, negatively correlated with SR Ca 2+-ATPase. CONCLUSION: Both irbesartan and perindopril decrease CaN activity, increase SR Ca 2+-ATPase activity and combination of them has synergic effects on regressing of ventricular hypertrophy.

The effects of D-polymannuronic sulfate (DPS) on the norepinephrine (NA) or potassium chloride (KCL)-induced contraction of rat aortic rings were studied in this paper. The results showed that DPS at the final concentration of Img ? L-1 inhibited the contraction of aortic rings e-voked by NA or KCL and shift doseresponse curves for NA or KCL to the right in a non-parallel fa-sion and depressed their maximal response, implicating that DPS afforded the noncompetitive antagonism on contraction of rat aortic rings induced by NA or KCL. This finding suggested that DPS exerted an inhibitory action of potential-dependent calcium channel and that of receptor-operated calcium channel in vascular smooth muscle.

Objective To analyze the clinical characteristics and treatment of post - renal acute renal failure (ARF)induced by Ceftriaxone in children. Methods The clinical data of 7 cases of post - renal acute renal failure in children from June 2012 to June 2014 induced by Ceftriaxone were analyzed. According to the changes in urine volume, serum creatinine,blood urea nitrogen and serum potassium level,liquid therapy,retrograde ureteral catheterization (RUC)and peritoneal dialysis was performed by step sequential therapy respectively. Results Seven cases were given intravenous Ceftriaxone under the fluid loss state. Abdominal pain,sudden anuria or oliguria appeared in the children af-ter 2. 6 d on the average,B ultrasonography and CT scanning showed multiple calculus in the bilateral renal pelvis and ureteral calculi. Blood BUN was 15. 2 - 37. 9 mmol/ L[(23. 3 ± 8. 6)mmol/ L],and blood Cr was 180 - 636 μmol/ L [(378. 9 ± 148. 4)μmol/ L]. These indicators met the diagnostic criteria for acute renal failure. In 7 cases,2 cases (28. 6% )received fluid therapy of sodium bicarbonate alkalization and anisodamine spasmolytic,4 cases(57. 1% )re-ceived fluid therapy and RUC,and 1 case(14. 3% )underwent fluid therapy and RUC and peritoneal dialysis. All of 7 cases(100% )were alive. In the average 4. 4 days renal function of 7 cases was returned to normal,and urine volume and electrolyte were also restored. Conclusions Step sequential therapy including fluid therapy,RUC and peritoneal dialysis is effective with post - renal ARF in children induced by Ceftriaxone.

DNA methylation is a normal modification mode of eukaryon, there is an intimate relationship between aberrant promoter methylation of tumor-related genes and the generation or development of neo- plasms,emerging significantly biological effectiveness. Aberrant promoter methylation of tumor-related genes as the epigenetic markers, maybe play a very important role in the incidence, diagnosis, therapeutic effects, prognosis judgements and other aspects in gallbladder carcinoma.

Objective To investigate the risk factors affecting early mortality in spontaneous rupture in patients with hepatocellular carcinoma (HCC)and explore the effective treatment.Methed A retrospective study of 34 consecutive patients with spontaneous rupture of HCC from January 1998 to January 2008 was conducted.Followup was conducted for more than 3 years.18 clinical ,biochemical and pathological factors influencing 30-day mortality were analyzed.Results 30-day mortality rate was 38% (n=13).Univariate analysis showed that presence of cirrhosis,Child's C status,shock on admission,higher blood transfusion requirement,raised α-fetoprotein (AFP),raised alkaline phosphatase(ALP)and raised aspartate transaminase(AST)were all associated with increased risk early death (P＜0.05).Multivariate analysis displayed that shock was an independent risk factor affecting early death.The median survival time was 14.4 months in 8 patiens receiving emergency curative rescection and 44.4 months in 5 cases underwent delayed curative resection,and the 1-and 3-year survival rate were 63% (5/8)and 13% (1/8)in the former group and 80% (4/5)and 60% (3/5)in the latter group.Conclusion Poor prognosis of spontaneous rupture of HCC is associated with poor liver reservation,advanced disease and large volume of haemorrhage.Shock and blood transfusion requirement are the independent factors affecting early mortality.Curative resection is a definite treatment and delayed curative resection following initial haemostasis has a safer and more effective result.

Objective To observe the effect of exogenous insulin on the expression of P-glycoprotein (P-gp)and the secretion of insulin in pancreatic beta cells (INS-1 832/13).Methods Insulinoma cells (INS-1 832/13) were cultured with 0.5 μmol/L exogenous insulin for 30 days.MTT assay was used to measure cell viability.Quantitative RT-PCR and western blot were used to detect the expression of P-gp mRNA and protein respectively,and glucose stimulated insulin secretion (GSIS) were measured by radioimmunoassay.Results Compared with control group,0.5 μmol/L exogenous insulin promoted the viability of INS-1 832/13 cells [(102.00±12.99) vs (356.00±35.51),P<0.05] and accelerated P-gp expression [(107.50±17.08) vs (307.50±44.25)] both at mRNA and protein levels [(105.00±12.91) vs (192.50±35.94),P<0.05].Glucose stimulated insulin secretion was positively correlated with P-gp expression level,but had no significant effect on basal insulin secretion.Conclusion Exogenous insulin can promote the secretion function of INS-1 832/13 cells,and the mechanism may be related to the expression of P-gp.
