Objective:To explore the Optimize concentrate process of loganin from Cornus officinalis by ultrafiltration-nanofiltration coupling technology. Methods:Based on single factor test, nanofiltration membrane pore size, transmembrane pressure difference and pH were selected as independent variables, and the rejection of loganin was used as dependent variables. Response surface methodology of Box-Behnken Design was applied to optimize the concentrate process of loganin from Cornus officinalis. Results:Ultrafiltration can remove polysaccharides and improve the filtrability of the solution. The optimum nanofiltration concentrate conditions were nanofiltration membrane pore size 400 Da, pH 6.7 and the transmembrane pressure difference was 1.20 MPa. The average cut-off rate of loganin was (91.9 ± 1.7)%, which was close to the theoretical cut-off rate of 93.6%.Conclusion:The loganin from Cornus officinalis has been concentrated efficiently by the combination of ultrafiltration and nanofiltration. The coupling technology is stable and feasible, whinc could avoid the transformation loss of heat-sensitive ingredients.

Abstract: Superior mesenteric veinous thrombosis (SMVT) is a rare complication that often occurs in conjunction with intra-abdominal diseases such as diverticulitis, appendicitis, inflammatory bowel disease, etc. Its clinical symptoms are non-specific and include fevers, abdominal pain; it has no specific symptoms, and the diagnosis depends on clinical laboratory tests and imaging studies. The occurrence of superior mesenteric veinous thrombophlebitis is related to septic phlebitis caused by the sloughing of the embolus containing bacteria into the portal vein with blood flow. Due to the nonspecific clinical features of this disease, diagnosing it based on clinical characteristics and microbiological aspects is a challenge. A case of superior mesenteric veinous septic thrombophlebitis caused by Bacteroides fragilis infection is reported and to provide a reference for the diagnosis and treatment of such diseases. The patient was a 34-year-old man who was admitted the hospital with intermittent abdominal pain and fever. Computed tomography (CT) showed partial thrombosis of the superior mesenteric vein, colonoscopy revealed diverticulitis in the ileoceca, and the blood culture grew Bacteroides fragilis. The patient was treated with anti-infection (ceftazidime 2.0 g q12h intravenous infusion for 11 days; metronidazole 0.5 g, q8h intravenous infusion for 3 days) and anticoagulation (rivaroxaban 20 mg qd orally for 8 days. On the 11th day of hospitalization, the patient's condition improved, and he was discharged. In this case, for patients with fever and abdominal pain, superior mesenteric venous thrombophlebitis should be included in the differential diagnosis. Through auxiliary examination, blood sample culture and other technologies, clear diagnosis should be made in time to improve patient outcomes.

Objective To evaluate the role of mierosurgery in surgical treatment to urethrocutaneous fistula after urethroplasty in hypospadias and improve surgical results.Methods From 1999 to 2006,44 urethrocutaneous fistulae (more than 3mm in diameter) after urethroplasty for hypospadias in 33 patients were repaired with different skin flaps.For example,Thiersch technique,urthroplasty,etc.Microsurgical tech- nique was employed in every case.Results The success rates of different procedure were 84.8% (28/33) for Thiersch technique,100% (11/11) for urethroplasty respectively.The total success rate was 88.6%(39/ 44).Conclusion It's just application of skin flap for repairing of big or complex urinary fistula after hypos- padias surgery.The application of microsurgical technique can increase success rate.It is necessary to excise scar and partial urethra for hypospadias fistula combined with urethral structures,cicatricial eontracture and in- curvation of penis.Rich blood-supply,low tension and atraumatic technique are all very important to improve surgery success rates of urinary,fistula after hypospadias repair.

Objective:To explore the effect of feeding via the transpyloric route on the gastrointestinal function in very low birth weight (VLBW) infants and find the best early enteral nutrition protocol.Methods:Sixty VLBW infants were randomly devided into transpyloric feeding group(TP group) (n =30) and intragastric feeding group(IG group) (n =30).The frequency of apnoea,weight gain,the time of birth weight regain,feed intolerance,time of reaching full enteral feeding,the incidence of extrauterus-growth retardation (EUGR),motilin,gastrin,the length of hospital stay,necrotizing enterocolitis and duodenal perforation were observed in two groups.Results:The intolerance and time of reaching full enteral feeding were reduced significantly during transpyloric feeding compared with intragastric feeding (P ＜ 0.05).The number of episodes of apnoea was decreased significantly during transpyloric feeding compared with intragastric feeding (P ＜ 0.01).Conclusion:Transpyloric feeding can be used in VLBW infants.
