Results Optimal ultrasound-assisted extraction technology was as following: the concentration of ethanol was 73%; the ultrasonic time was 22 min; the ratio of liquid to material was 1:32. The contents of Epimedin C and Icariin from Epimedii Wushanensis Herba were 15.90% and 0.75%, respectively. Conclusion This extraction technology can improve the extraction efficiency of Epimedin C and Icariin from Epimedii Wushanensis Herba, which is in accordance with predicted value.

Objective To investigate the relationship of pancreatic exocrine function with the pancreatic cancer staging and the size of tumor. Methods N-benzoyl-tryrosyl para-aminobenzoic acid (NBT- PABA) test was used to measure the pancreatic exocrine function of 39 pancreatic cancer patients, 46 chronic pancreatitis patients and 20 normal subjects. In pancreatic cancer group, the relationship of pancreatic exocrine function with the size of tumor (TS) and JPS classification (T factor) was analysed. Results The rate of NBT-PABA excretion in normal subjects, chronic pancreatitis patients were (78.9±15.9)%, (58.6± 19.3)%, respectively; in mild, moderate, severe chronic pancreatitis patients, the values of NBT-PABA were (75.5±23.6)%, (57.9±21.5)%, (45.5±16.7)% ; respectively. The rate of NBT-PABA excretion in pancreatic cancer patients was (47.6±18.3)%, and the rate of NBT-PABA excretion in patients with T3+T4 stage was (42.2±21.70%, and was obviously less than (64.8±11.2)% of T1+T2 stage (P<0.05). Tthe rate of NBT-PABA excretion in patients with TS3+TS4 was (34.8±17.2)%, and was significantly lower than (55.6±23.5)% of TS1+TS2(P<0.05). The rate of NBT-PABA excretion in patients with pancreatic head cancer was (42.5±16.4)%, which was significantly lower than (71.8±9.6)% of the pancreatic body and tail (P<0.05). In the 33 patients with pancreatic head cancer, the rate of NBT-PABA excretion in patients with main pancreatic duct stricture was (54.2±14.1) %, which was significantly higher than (37.6± 14.1)% of patients with main pancreatic duct interruption (P<0.05). There was no significant difference in pancreatic exocrine function between pancreatic cancer and moderate or severe chronic pancreatitis.Conclusions The pancreatic exocrine function was related to the pancreatic cancer staging and the size of tumor to some degree,but it was affected by mass location,and it was also affected by degrees of the pancreatic duct obstruction. The pancreatic exocrine function can not be used to differentiate pancreatic cancer from moderate or severe chronic pancreatitis.

Objective To explore the relationship between fatty liver and body mass index (BMI), serum lipid levels in aging population. Method 748 of retired people (≥45 years) were studied. All participants accepted liver B -mode Ultrasonography examination, height, weight and blood lipid detection. The relationship between Fatty Liver and BMI, serum lipid levels were analyzed. Results The detection rate of Fatter Liver in male and female was 61.8% and 44.6% separately. The detection rate of Fatter Liver was 53.4% in the aging group (45~59 years), while the rate was 51.0% in elderly group (≥60 years). Compared to the 23.07 kg / m2 and 1.58 mmol/L in group without fatty liver, the BMI and serum triglyceride was 26.77 kg / m2 and 2.13 mmol / L in the group suffered the Fatter Lever. There existed statistically significant differences of Body Mass Index and serum Triglyceride level between the group with and without fatty liver (P

Ulcerative colitis (UC) is a subtype of inflammatory bowel disease. Its pathogenesis is not clear and the pathogenesis is complex. Moreover, it is recurrent and its healing is delayed. It is a kind of refractory disease. Its incidence and recurrence rate showed a trend of increasing year by year in our country at present. At the present stage, the main treatment focuses on glucocorticoids, aminosalicylic acid, immunosuppressor and biological agent. Although biological agent can greatly improve the efficacy, there are many problems in clinical treatment for a small amount of refractory patients. The comprehensive intervention combined with non-drug treatment should be performed, so as to achieve the curative effect. Fecal microbiota transplantation (FMT) has attracted people′s attention in recent years. It displays a certain therapeutic effect on the treatment of UC in the active stage, especially refractory recurrent UC. Therefore, the domestic and overseas FMT treatment are summarized in the paper.
