Adenoid hypertrophy is a disease that mostly occurs among children of 3-5 years old. It is caused by repeated inflammation and infection of nasopharynx and its adjoin parts, or the adenoid itself, which will finally leads to pathological hyperplasia of adenoid. With so much information we have acquired about this disease, its specific mechanism remains unknown. In recent years, some researches have indicated that adenoid hypertrophy may have something to do with extra-gastroesophageal reflux, in which pepsin plays a very important role, and pepsin will do a series of pathological damages to the upper airway as it reaches the upper respiratory tract. Based on relative domestic and foreign literature, this paper attempts to make a review about the relationship between gastroesophageal reflux and adenoid hypertrophy.

Objective:To investigate the association between the apolipoprotein A5(APOA5) -1131T/C polymorphism and premature coronary heart disease in northern Chinese Han population. Methods: Using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and polyacrylamide gel electrophoresis (PAGE), we analyzed the genotype and allele distribution in 140 patients with premature coronary heart disease diagnosed by coronary angiography and 156 healthy controls. The levels of serum lipid profiles were also studied by biochemical methods. Results: The allele frequency of APOA5-1131T/C polymorphism in the premature coronary heart disease group was significantly higher (43.2% vs. 33.0%, P=0.011) than that in the control group. Compared with TT homozygotes, CC homozygotes exhibited a 2.809-fold (95% CI 1.331-5.927) increased risk of developing premature coronary heart disease. Logistic regression analysis found that this correlation was independent of sex, age, body mass index (BMI), smoking history as well as serum total cholesterol(TC), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) levels; In premature coronary heart disease group, the triglyceride(TG) level in CC homozygotes was significantly higher than those in TC heterozygotes or TT homozygotes. Conclusion: The APOA5-1131T/C polymorphism has influence on serum TG level, and the APOA5-1131C allele is associated with the development of premature coronary heart disease in northern Chinese Han population.

BACKGROUND: Non-invasive vascular ultrasound is used to assess in tima-media thickness (IMT) and atheromatous plaque, of which the result is better correlated to that of pathological examination. OBJECTIVE: Non-invasive vascular ultrasound was used to assess the hemodynamical changes of external and internal carotid in hypertensive elders, so as to investigate the relationship between pulse pressures, left ventricular mass index (LVMI), vascular resistance index (VRI) and shearing ratio. DESIGN: Randomized, controlled, correlative analyzedstudy. SETTING: Ultrasound Department of Affiliated Hospital of Jiangshu University. PARTICIPANTS: Totally 54 hypertensive elders, including 33 males and 21 females, were recruited from the Ultrasound Department of Affiliated Hospital of Jiangshu University, from September 30th 2000 to March 30th 2002. Meanwhile 26 normotensive elders (systolic pressure < 130 mm Hg and/or diastolic pressure < 85 mm Hg), including 16 males and 10 females, were selected as controls, METHODS: Color duplex blood flow imaging technique was used to assess the left ventricular end-diastolic diameter (LVEDD) and the interventricular septum thickness (IVST), so as to calculate the LVMI. The insiddiameter of bilateral common carotid artery (CCA) and internal carotid,IMT, the systolic peak flow velocity and resistance index were measured in order to calculate the vascular shearing ratio and atheromatous plaque index,moreover arterial pressure, LVMI, as well as resistance index and shearing ratio were subjected to linear correlative analysis,of which the results were compared with that of control group. MAIN OUTCOME MEASURES: ① Pulse pressure, LVMI and atheromatous plaque index of CCA. ② The inside diameter of bilateral CCA and internal carotid, IMT and the systolic peak flow velocity and resistance index were measured in order to calculate the atheromatous plaque index and maximum vascular shearing ratio. RESULTS: According to the experimental objective,data of all 80 cases were analyzed without loss. ① The pulse pressure and LVMI, the incidence of atheromatous plaque and plaque index of CCA in hypertensive elder group were obviously higher than that of control group [(64.36±7.44) mm Hg,(45.78±8.72) mm Hg; (131.47±18.73) g/m2, (83.28±12.34) g/m2; 5.62 ±1.78,3.44±1.10; 66.7%, 23.1%, (x2=13.37, t=5.730-13.234, P < 0.01)]. ② The inside diameter of bilateral CCA and internal carotid, IMT and resistance index in hypertensive elders were significantly higher than that of control group [CCA: (8.96±1.20) mm, (8.08±0.96) mm; (1.28±0.88) mm, (0.91±0.17) mm;0.75±0.05, 0.69±0.06; ICA: (6.82±1.12) mm, (5.72±0.92) mm; (1.06±0.17) mm,(0.76±0.15) mm; 0.70±0.07, 0.64±0.06, t=2.872-10.850, P < 0.01], but the systolic peak flow velocity and shearing ratio were markedly lower than that of control group [CCA: (47.44±12.85) cm/s, (60.20±14.32) cm/s;(225.78 ±95.76)/s, (300.26 ±110.42)/s. ICA: (41.22 ±10.18) cm/s,(48.64±11.58) cm/s; (268.54±112.56)/s, (324.52±121.42)/s, t=2.872-10.850, P < 0.01]. ③ The pulse pressure, LVMI, the resistance index of CCA and ICA and shearing ratio were linearly correlated (r=0.30-0.36, P < 0.05). CONCLUSION: Pulse pressure and LVMI were found increased in hypertensive elders, together with carotid vessels dilated, IMT and resistance index increased, as well as shearing ratio decreased, atheromatous plaque formed, vascular stiffness increased, which resulted in consequently decrease of vascular compliance.

Objective To study the solute clearance effect of the new concentrated anticoagulation hemodiaiysate of citrate for hemodialysis in patients with high risk of bleeding. Methods Forty-two kidney failure patients with high risk of bleeding were divided into two groups (Group A and Group B) according to their hemodialysis manners. Patients in Group A were hemodialyzed with bicarbonate hemodialysate with low-molecular-weight heparin (dalteparin) anticoognlation and those in Group B with the new citrate antieoagnlation hemodialysate prepared in our hospital without any other anticoagulant. Blood urea nitrogen (BUN) and creatinine (Cr) concentrations were measured before and after dialysis, and Kt/V and urea reduction rate (URR) were calculated. In addition, activated clotting time (ACT) and ionized calcium (iCa2+) concentration were also measured at the arterial and venous ends. Results ACT was extended and iCa2+ concentration decreased significantly at the venous end compared with those at the arterial end in Group B (P<0.01). BUN and Cr concentrations were markedly decreased after dialysis compared with those before dialysis in both groups (P<0.01), and no significant difference in solute clearance effect, as indicated by Kt/V and URR, was observed between Group A and Group B (P>0.05). Conclusion The solute clearance effect of the new concentrated anticoagnlation hemodialysate of citrate is excellent during hemodiaiysis in kidney failure patients with high risk of bleeding.
