A high performance liquid chromatographic method with hypersil C_(18) column, 0.020 mol/L potassium dihydrogen phosphate solution(which contains 0.25% triethylamine, pH 5.1)-methanol(20∶ 80, V/V) as mobile phase and fluorescence detection with 280 nm as excitation wavelength and 320 nm as emission wavelength has been developed for the determination of terbutaline sulfate and propranolol hydrochloride in Erythrocyte suspensions. Erythrocyte surface receptor oscillating reacted 1 h with terbutaline in 37 ℃ water bath. Free terbutaline and propranolol were separated from the membrane receptor-binding complex through 1500 r/min centrifugal in 5 min. The linear range was 0.010-3.000 mg/L in Alsever's solutions and the correlation coefficients were 0.9999 and 0.9998. The relative standard deviations(RSDs) of terbutaline and propranolol were 0.8% and 1.2%, respectively. The limits of detection(LODs) of both were 1.00 and 3.00 mg/L. This simple, safety and sensitive method was suitable for the determination of terbutaline and propranolol in erythrocyte suspensions and for the study of receptor-ligand binding.

Objective To investigate good nutritional measurements of CKD patients.In order to diagnose malnutrition early in CKD patients.Methods Clinical data of 125 CKD patients have been collected.The glomerular filtration rate(GFR)was estimated from the modification of diet in renal disease(MDRD).According to the results of GFR,all CKD patients were divided into five groups.The levels of biochemical markers were assayed.At the same time,bioelectrical impedance analysis(BIA)were measured.We analyzed the relationship between nutritional parameters and GFR.Results According to SGA,malnutrition rate in fifth CKD stage is 29%.Impedance of leg is significantly correlated to GFR in 1kHz,50kHz and 500kHz,impedance of truck is also significantly correlated to GFR in 50kHz and 500kHz.The values of impedance reduced with the decreasing of GFR.Conclusion SGA and BIA all can be used to evaluate nutritional status of CKD patients.BIA is a more sensitive method to detect early malnutrition and may be useful in monitoring nutrition changes in CKD patients.

The trial group (n=30) received peptisorb 3days before and 7days after operation. Control group (n=30) received coloclysis treatment.The the level of Alb, globulin,the number of IgG, IgA,IgM, CD3+,CD4+/ CD8+ ,the station of intestinal mucosa and intestine cleaning during operation, nutritional state after operation, immune function, infcetious complications, length of stay were detected.Results: There were no significant difference in the station of intestinal mucosa and intestine cleaning. The index of nutritional and immune in two groups were descend, but the trail group was better(P＜0.01). The number of IgG,IgA, IgM, CD3+ in the trail group were significantly higher than the control group(P＜0.01),the rate of postoperative infectious complications in the trail group was lower than the control group.The trail group aslo showed shorter average length of stay after surgery than the control(P＜0.01).Conclusion: The peptisorb can ameliorate the host immune function and improve clinical outcome,which is a good nutrition support pathway to perioperative colorectal cance patinets.

Sulfotransferase (SULT) enzymes play important roles in the biosynthesis of estrogen.These enzymes catalyze the sulfation of estrogens to form biologically inactive molecules. Several studies have shown that Arg213His polymorphism in SULT1A1 gene may be a risk factor for breast cancer. In addition, a low mRNA expression of SULT has been significantly associated with reduced recurrence and improved overall survival in patients with estrogen receptor (ER)-positive tumors. Furthermore, SULT may be a crucial factor in the response to tamoxifen treatment. As an important part of estrogen synthetic pathways, SULTs are closely re lated to breast cancer.

Atrial fibrillation is one of common arrhythmias and can significantly increase risks of stroke and heart failure with high rates of mortality and disability. The incidence of atrial fibrillation increases year by year due to aging population, high incidences of coronary heart disease and hypertension, and lifestyle changes. As one of widely consumed drinks in the world, coffee affects the daily life of modern people. The intake of caffeine, which is the main ingredient of coffee, can influence the incidence of atrial fibrillation, but the relationship between them is still controversial. Most studies deem that the intake of caffeine is negatively correlated with the incidence of atrial fibrillation. This paper reviews current studies in China and abroad on the relationship between the intake of caffeine and the incidence of atrial fibrillation.

Objective To evaluate the clinical effectiveness of laparoscopic cholecystectomy ( LC) combined with endoscopic sphincter-otomy ( EST) for treatment of gallstones with common bile duct stones. Methods Clinical data of 652 patients who were treated by LCs and ESTs were retrospectively analyzed. Results ESTs were successfully accomplished in 634 patients (97. 2%), and LCs were successfully ac-complished in 621 among the 634 patients (97. 9%) after ESTs. The mean length of hospitalization after LCs was 4 days (2~15 days). In all 652 patients, there were 233 cases of acute pancreatitis, including 171 cases before ESTs and 62 cases (13. 1%) after ESTs, and they were all cured after ESTs. In 621 patients after LCs, bile leakages occurred in 8 patients (1. 2%) and they were cured with intraoperative drainages. Local fluid accumulations occurred in 120 patients (19. 0%), and 118 cases of them healed without management, and the other 2 cases were cured with percutaneous tube-placement drainages guided by ultrasonography because of abscesses. Conclusion It is safe and effective to treat gallstones with common bile duct stones by LC combined with EST because of its high success rate, short hospital stay and mild complications.
