Objective The aim was to investigate the manupulation and the localization of LV Lead, and to evaluate LV Lead usefulness in biventricular pacing.Methods 9 Patients with enlarged left ventricle, chronic heart failure, CLBBB and refractory to chemical therapy were selected in this study, including 8 males and 1 female. Coronary sinus venography was performed by injecting contrast medium retrogradely at coronary sinus ostium in 7 cases or antegradely into left coronary artery in 2 cases. LV lead was introduced to CS and localized at targeting vein of LV through a "peel away" guiding sheath, which was placed in CS via left subclavian vein route. Results Coronary sinus and its tributaris were clearly visualized by both antegrate cardiac venography and retrograte cardiac venography. 2187 leads were implanted into targeting veins through "peel away" guiding sheaths in 6 cases and directly introduced in 2 cases, while in other case the lead was inserted into coronary sinus directly after a failed procedure via a "peel away" guiding sheath. The leads were placed in great cardiac vein in 1 case, lateral LV vein in 2 cases, left posterior LV vein in 2 case and left posterolateral veins in 4 cases. The acute pacing and sensing thresholds measuered during the implanting procedure were in normal limits. 2187 leads were still fully functional without dislocalization during follow up of average 253 days. Conclusion CS and its tributaries can be clearly shown by antegrate and retrograte venographies. The introduction of 2187 left ventricular pacing is easily performed directly or through a preformed "peel away" guiding sheath. LV epicardium pacing by 2187 LV lead implanted through CS is feasible and reliable.

Objective To wmpare the differences of the mixing time and contamination rate between liquid and powder EN preparations. Methods 20 patients,receiving enteral nutrition for more than 6 days, were enrolled in. this study. They were randomized to receive either powder enteral diet (control group, n=10) or liquid enteral diet (study group, n=10). The mixing time was examed by stopwatch. The contamination rate was determined by culture of bacteria in the solution. Results 1. The mixing time of study group was significantly shorter than that of control group ( 18.9 ± 3.0 vs 106.0 ± 21.0 , P<0. 001). 2. The bacterial culture in both groups were negative before enteral feeding. There was no positive case in study group and only 2 positive eases in control group after infusion. However, there was no statistical difference between the two groups ( P=0.14). Conclusions Liquid form of enteral nutfitent was less time cost and no ease contaminated by enveriorment, but it is expensive. he ligurd preparation has more advantages than powdor one in mixing time and comtamination.

ObjectiveTo review the experience on the diagnosis and surgical treatment nonfunctional islet cell tumors (NIT) of the pancreas. MethodsData of 32 NIT patients of the pancreas during the past 46 years in Tianjin Cancer Hospital were analyzed retrospectively.ResultThe average of patients was 32 years old,with female to male ratio of 2.6∶1. The major symptoms included abdominal mass, bellyache, abdominal distension, obstructive jaundice, and back pain. The average diameter of the tumor was 9 cm. Tumors were single in 94% of all cases and multiple in 6%. Tumors located in the head of pancreas in 47% of all cases, in the body in 16%, in the tail in 31%. Tumors were malignant in 69%(22/32) and benign in 31% (10/32 ) .Pancreaticoduodenectomy was performed in 22%, resection of the spleen and pancreatic body-tail in 34%, resection of the body and tail of the pancreas in 16%, biopsy and biliary-enterostomy in 13%, tumor enucleation in 9%, biopsy only in 6%. The main postoperative complications were pancreatic fistulae (25%) and wound infection (9%). The 1? 3 and 5-year survival rates of malignant patients were 90%, 80% and 69%, respectively.ConclusionNIT is often single and large at the time when the patients sought medical consultation. The postoperative prognosis of patients with malignant tumor is favorable.

The absorption of 59 Fe incorporated into yeast was studied in rats. Yeast was cultured in a nutrient solution to which radioactive 59Fe was added as an intrinsic tag. The 59Fe-enriched yeast was separated from the solution by centrifuge and given to rats by a stomach tube. The rats of the control groups were given the radioactive " Fe together -with ordina-ly yeast plus ferrous sulfate or only with ferrous sulfate separately.All feces were collected until less than 0.5 per cent of the administered dose was present in a 24-hour specimen of feces. The radioactivity in the feces was then measured daily for three successive days. The absorption of iron was calculated by the difference between intake and fecal loss.The result revealed that the absorption of iron in "Fe-enriched yeast (38.7%) was similar to that of ferrous sulfate (38.3%). It indicated that the iron incorporated into yeast was easily to be absorbed.This study afforded the scientific data for researching and popularizing fortified food with iron-enriched yeast.

Objective: To evaluate the efficacy of intraoperative hyperthermic peritoneal perfusion (CHPP) on advanced gastric carcinoma. Methods: Sixty patients with advanced gastric carcinoma were divided into the control group and the treatment group. All patients underwent radical gastrectomy and D2 node dissection. Patients in the treatment group received CHPP when surgical resection was completed. Patients in the control group underwent resection of gastric carcinoma without CHPP. Chemotherapy was administered with FOLFOX4 regimen intravenously for 12 cycles in both groups at 4 weeks after surgery. The serum Carcinoembryonic antigen (CEA) and CA19-9 were measured in patients with advanced gastric cancer before and after resection of tumor. Survival and recurrence in both groups were analyzed and compared. Results: The mean levels of the expression of CEA and CA19-9 in the peripheral blood of the 60 patients were significantly higher than the upper limits of normal (55.89±22.25μg/L vs 0~5μg/L; 125.35±61.78 U/mL vs 0~39U/mL P< 0.01). There were no significant differences in the mean levels of the expression of CEA and CA19-9 in the peripheral blood between the treatment group and the control group (54.67±22.95μg/L vs 56.09±22.15μg/L; 126.16±62.45 U/mL vs 123.35±60.88 U/mL,P>0.05). The serum CEA and CA19-9 levels were significantly decreased at 7 days after treatment in the treatment group (7.58±3.21 μg/L, 31.35±13.47 U/mL, P<0.01). The levels of these two tumor markers were decreased unremarkably at 7 days after treatment in the control group (37. 68±20.59μg/L, 98.23±36.28 U/mL, P>0.05). The serum CEA and CA19-9 levels were decreased significantly in both groups at 30 days after surgery (P<0.05). One-year survival and recurrence rates were 83.3% and 10% in the treatment group and 80% and 13.3% in the control group, with no significant differences between the two groups (P>0.05). Three-year survival and recurrence rates were 63.3% and 20% in the treatment group and 40% and 40% in the control group, with a significant difference between the two groups (P<0.05). Conclusion: Surgical resection combined with CHPP can significantly decrease the serum CEA and CA19-9 levels. Intraoperative CHPP for patients with advanced gastric carcinoma is helpful for preventing peritoneal metastasis and recurrence and can prolong survival time.
