OBJECTIVETo evaluate the application of side-to-side anastomosis of the lesser curvature of stomach and jejunum in laparoscopic Roux-en-Y gastric bypass (LRYGB).
METHODSClinical data of 29 patients with type 2 diabetes mellitus (T2DM) undergoing side to side anastomosis of the lesser curvature of stomach and jejunum in LRYGB from May 2012 to November 2012 in Department of General Surgery, Beijing Tiantan Hospital, Capital Medical University were analyzed retrospectively.
RESULTSAll the procedures were successfully completed without conversion to laparotomy. The side-to-side anastomosis of the lesser curvature of stomach and jejunum avoided the laparoscopic suture. No gastrojejunostomy anastomotic bleeding, fistula, obstruction and other complications occurred after operation and no complications of gastrojejunostomy anastomosis were found during a follow up of 1 to 7 months.
CONCLUSIONSSide-to-side anastomosis of the lesser curvature of stomach and jejunum in LRYGB can manipulate the size of anastomosis accurately and avoid the laparoscopic suturing. It is simple and easy to learn.

OBJECTIVETo observe postoperative glucose tolerance, gastric inhibitory polypeptide (GIP) , and glucogan-like peptide-1 (GLP-1) in normal glucose level dogs after undergoing gastric bypass procedures, and to explore the mechanism of gastric bypass procedures to treat type 2 diabetes.
METHODSThe 6 dogs with normal glucose tolerance had undergone gastric bypass procedures, and measure preoperative and postoperative oral and intravenous glucose tolerance (at time points 1, 2, and 4 weeks) through changes in blood glucose, insulin, gastric inhibitory polypeptide (GIP), glucagon-like peptide-1 (GLP-1), and measure preoperative and postoperative week 4 pancreatic tissue morphology.
RESULTSSecond weeks after operation, the fasting blood sugar was (3.58 ± 0.33) mmol/L, and significantly lower than preoperative (t = 3.571, P < 0.05). The GLP-1 level before oral glucose tolerance test (OGTT) and 30 minutes after OGTT were (0.90 ± 0.21) and (0.91 ± 0.19) pmol/L respectively, and significantly higher than preoperative (t value were -3.660 and -2.971, P < 0.05). GLP-1 levels began to decrease in the second week after surgery. After 4 weeks, the index recovered to the preoperative level. Four weeks after surgery when compared with preoperative, islet morphology, islet number (6.8 ± 0.8 and 7.1 ± 0.8 respectively) and islet cells (16.7 ± 2.5 and 16.3 ± 3.1 respectively) did not change significantly (P > 0.05).
CONCLUSIONGastric bypass procedures could be briefly affect normal glucose tolerance in dogs' blood glucose, insulin and diabetes-related gastrointestinal hormones.

OBJECTIVE: To report an overview of bariatric & metabolic surgery performed in 2018 in North China. METHODS: Based on prospective and observational North China Bariatric & Metabolic Surgery Clinical Database(NC-BMD), the study of evaluating the number and the type of bariatric &metabolic surgery procedures was performed in North China. Demographic characteristic, obesityrelated diseases and operational information were also analyzed. RESULTS: In 2018, 17 centers from 7 regions in North China contributed a total of 728 registration data. Valid data were analyzed from 16 centers. The patients' median (minimum, maximum) BMI pre-surgery was 38.4(24.7,95.2). The overall proportion of female patients was 74.7%, and mean±SD age was(32.5±8.29) years, while male patients was 25.3%, and mean±SD age was (32.7±9.90) years. According the data 93.9% laparoscopic sleeve gastrectomy(LSG), 4.4% laparoscopic Roux-en-Y gastric bypass (LRYGB) and 1.7% other operation types. 29.2% of patients had a history of type 2 diabetes, 69.4% had sleep apnea, and 22.6% had polycystic ovary syndrome before operation. CONCLUSION: The establishment of NC-BMD has laid a solid foundation for data registration in North China. Based on current data, LSG is the mainstream of bariatric and metabolic surgery in North China this year.

Aim To analyze the molecular mechanism of rhubarb in the treatment of aeute pancreatitis ( AP) by network pharmacology and molecular docking.Methods TCMSP,TCMID and Swiss target predic¬tion databases were used to screen the active compo¬nents and targets of rhubarb,and genecards and OMIM databases were used to screen the targets of AP.Then the active ingredient drug target network of rhubarb and theactive ingredient disease target network of rhubarb for AP were constructed by using Cytoscape software.PPI network was constructed in string database, and go and KEGG enrichment analysis was performed in metascape database and R language.Finally,molecular docking was used to verify the possibility of binding the core active components to the core target.Results A total of 192 active components and 1 882 AP targets were obtained.The first three active components of rhubarb in the treatment of AP were beta sitosterol, aloe emodin and eupatin.The core target of rhubarb in the treatment of AP was hsp90aal.Go enrichment analysis focused on reaction to toxic substances, while KEGG enrichment analysis was significantly enriched in p53 signaling pathway closely related to AP.Molecular docking showed good binding and stable conformation.Conclusions Rhubarb can affect the expression of AP related genes and proteins through p53 signaling pathway, thereby inhibiting cell apoptosis and allevia¬ting the inflammatory injury of AP.

OBJECTIVETo explore the differentiation-inducing potentiality of Pulsatilla saponin A on K562 cells.
METHODSPulsatilla saponin A of different concentrations was used to treat K562 cells; the benzidine staining and the hemoglobinometry were applied to measure the change of hemoglobin content; the flow cytometry (FCM) was used to detect the expression of CD71 and GPA on K562 cells.
RESULTSK562 cells treated with 4 µg/ml pulsatilla saponin A differentiated into the erythroid lineage. With the treatment of pulsatilla saponin A, the hemoglobin content in K562 cells increased significantly; CD71 and GPA expression on the K562 cell surface were up-regulated.
CONCLUSIONPulsatilla saponin A can induce K562 cells to differentiate into erythroid lineage.
