Objective To investigate the effect of Xuesetong Dripping Pills combined with alprostadil intervention on serum brain natriuretic peptide in elderly patients with chronic congestive heart failure.Methods In 74 patients with chronic congestive heart failure, were randomly divided into observation group and control group, 37 cases in each group.Control group received conventional method.The observation group received Xuesetong Dripping Pills combined with alprostadil on the basis of conventional therapy.Compared the efficacy, the heart function level, walking test and level of serum brain natriuretic peptide between two groups after 15 days’ treatment.Results The total efficiency of observation group was 94.59%, which was higher than 75.68% in the control group, the difference was statistically significant(P<0.05).After treatment, the heart function level improvement in the observation group was better than the control group, the difference was statistically significant(P<0.05).After treatment, 6 min walking test in the observation group(316.4 ±20.7) m, was better than the control group(303.5 ±28.1) m, the difference was statistically significant(P<0.05).The level of serum brain natriuretic peptide in the observation group(608.9 ±158.1)ng/L, was lower than that of the control group(792.7 ±179.4) ng/L, the difference was statistically significant ( P <0.05 ) .Conclusion Xuesetong Dripping Pills combined with alprostadil has good curative effect in the treatment of chronic congestive heart failure,can relieve the abnormal increase of serum brain natriuretic peptide, improve blood circulation and heart function.

It has been confirmed clearly that gastric bypass operation could be used for tbe treatment of type 2 diabetes mellitus.However,the curative mechanism underlying this therapy remain unclear up to now.Referencing the curative mechanisms research progress from domestic and abroad,the possible mechanism is considered as the secretion of gastrointestinal hormones can be changed after gastric by~ss operation,which has altered the normal anatomy structure of the gastrointestinal,and so as to the situation of type 2 diabetes mellitus can be controlled.This review will summarize recent papers related to mechanism research about the gastric bypass operatiou for the treatment of type 2 diabetes mellitus.

OBJECTIVE:To optimize the extraction technology of total saponins from Coreopsis tinctoria. METHODS:Etha-nol leaching technology was adopted. Based on single factor test,the extraction technology was optimized by orthogonal test using extraction temperature,ethanol volume fraction,extraction time,solid-liquid ratio as factors,extraction rate of total saponins as in-dex. The optimized technology was validated. RESULTS:The optimal technology was that ratio of solid to liquid was 1:30 (C. tinctoria-60% ethanol),extracting for 2 h at 50 ℃. Validation test showed that average extraction rate of total saponins was 6.8%(RSD=0.85%,n=3). CONCLUSIONS:The optimized technology can be used for the extraction of total saponins from C. tinc-toria and keep stable.

Objective To compare the clinical value of early enteral nutrition and parenteral nutrition therapy in postoperative patients of cholangiocarcinoma.Methods 56 cases of cholangiocarcinoma patients were randomly divided into early enteral nutrition group (EPN group) and parenteral nutrition group (PN group).All patients received nutritional support on the basis of metabolic support.Leukocyte count and neutrophil percentage decrease rate,total bilirubin decrease rate and hepatase (valley-C conversion) were counted at 3 and 7 days after operation.The decrease rate of aminase and glutamic oxaloacetic transaminase,recovery time of intestinal function (anal exhaust and defecation),incidence rate of surgical site infection (abdominal cavity and wound),hospitalization time after operation,incidence rate of bile leakage and hospitalization cost were compared between the two groups.Results The recovery time of intestinal function [(51.2 ±4.4) h],the decrease rate of leukocyte count (0.438 7 ±0.191 5) and neutrophil ratio (0.179 5 ± 0.046 1),the decrease rate of bilirubin (0.502 5 ± 0.153 5),alanine aminotransferase (ALT) (0.688 1 ±0.113 3),aspartate aminotransferase (AST) (0.617 0 ± 0.178 8) and hospitalization expenses [(87 852.37 ±9 127.04)yuan] in EPN group were better than those in PN group [(72.0 ± 12.9)h,0.090 5 ±0.120 3,0.083 4 ±0.036 8,0.201 5 ±0.077 8,0.251 6 ±0.419 0,0.230 9 ± 0.437,(109 036.69 ± 7 949.71) yuan,P ＜ 0.05].However,the incidence of abdominal distension (42.31％) was higher than that of PN group (13.33％,P ＜ 0.05).The incidence of bile leakage (7.69％) was not significantly different from that of PN group (13.33％,P ＞0.05).Conclusions Early enteral nutrition has obvious advantages in postoperative recovery of patients with cholangiocarcinoma.
