Objective To explore the application value of end-to-side closed in situ pancreaticojejunostomy in pancreaticoduodenectomy.Methods The clinical data of 22 patients with obstructive jaundice who were admitted to the Second Affiliated Hospital of Harbin Medical University from January to March 2014 were retrospectively analyzed.All the patients were explored whether tumors invaded inferior vena cava, superior mesenteric vein and portal vein after gallbladder decompression under general anesthesia by tracheal intubation.The standard or extended pancreaticoduodenectomy was applied according to the intraoperative results.The method of pancreaticojejunostomy was end-to-side closed in situ anastomosis of pancreatic duct and jejunal seromuscular layer.The operation time, intraoperative blood loss, postoperative gastrointestinal function recovery time, amylase concentration of drainage at postoperative day 1,3,5, postoperative complication, pathological classification and duration of hospital stay were observed.Patients were followed up by outpatient examination and telephone interview till May 2014.The out-patient follow-up included color Doppler ultrasound examination of effusion near the pancreatic stump, and the telephone interview included whether there were diarrhea of exocrine pancreatic insufficiency.Measurement data with normal distribution were presented as-x ± s (range) , and measurement data with skewed distribution as M(range).Results All the 22 patients underwent successfully the operation, including 17 undergoing standard pancreaticoduodenectomy and 5 undergoing extended pancreaticoduodenectomy, with end-to-side closed in situ anastomosis of pancreatic duct and jejuna seromuscular layer.The operation time of pancreaticoduodenectomy and end-to-side closed in situ pancreaticojejunostomy were (313 ± 37)minutes (range, 228-360 minutes) and(13 ± 4) minutes (7-22 minutes) , respectively.The intraoperative blood loss was (400 ± 207) mL (range, 100-800 mL).The mean tumor size was 3.69 cm2(range, 0.72-1.68 cm2).The recovery time of gastrointestinal function was (5 ±2)days (range, 4-7 days).The serum amylase at postoperative day 1, 3, 5 in the 21 patients was (145±30)U/L (range, 116-180 U/L), (136±40)U/L (range, 105-176 U/L), (147 ±38)U/L(range, 110-175 U/L), and the drainage amylase was (220 ±56)U/L (range, 172-289 U/L), (240 ±54)U/L (range, 192-300 U/L) , (245 ± 52) U/L (range, 190-298 U/L) , respectively.The serum amylase at postoperative day 1, 3, 5 in the patient with pancreatic fistula was 156 U/L, 178 U/L and 177 U/L, and the drainage fluid amylase was 500 U/L, 620 U/L and 605 U/L, respectively.There was 1 patient in the 22 patients with pancreatic duct stent and without death.Among the 4 patients with postoperative complications, 1 patient with grade A postoperative pancreatic fistula recovered after continuous external drainage, the other 3 including 1 case of infection,1 case of pneumonia and 1 of stress ulcer bleeding also recovered after symptomatic and supportive treatment.Postoperative pathological examinations of the 22 patients showed 12 cases of ductal adenoeareinoma, 2 of neuroendocine tumors, 1 of simple cyst, 1 of cystadenocarcinoma, 1 of squamous carcinoma, 1 of adenocarcinoma, 1 of ampullary carcinoma, 1 of tubular adenoma, 1 of leiomyoma and 1 of atypical intraductal hyperplasia.The average length of hospital stay was (11 ±3)days (range, 2-15 days).There were no effusion near the pancreatic stump showed in color Doppler ultrasound examination and diarrhea of exoerine pancreatic insufficiency.Conclusion End-to-side closed in situ pancreaticojejunostomy is safe and feasible, and can be applied to any pancreatic duct size and texture.

The acute phase of ischemic stroke patients are often treated with both Chinese patent medicine:and western medicine therapies in clinical practice. This research included 27,678 cases of the acute phase of ischemic stroke came from 14 3A level hospitals. We collected data from patients with ischemic stroke who used both Chinese patent medicine and western medicine and were hopitalized within 14 days from hospital information system (HIS). Constructing complex network of Chinese patent medicine and western medicine were found to show scale-free network. Hierarchical structure of the core algorithm was used to analyze the characteristics of combined core Chinese patent medicine and western medicine in admission condition of "acute", "critically", and "general" of ischemic stroke acute phase patient within one day, 2-3 days, 4-7 days and 8-14 days. We found that the core Chinese patent medicine mainly used for activate blood and resolve stasis medicine, and phlegm eliminating brain refreshing medicine in all kinds of patients, but the phlegm eliminating brain refreshing medicine were used to reduce with time elapsing. The core western medicine mainly used for anti-platelet medicine, improve circulation medicine, neuroprotective medicine, anticoagulants medicine and dehydration medicine. The dehydration medicine as the core western medicine for critically patients within 14 days, but the patients for general admission as core western medicine within 3 days. The neuroprotective medicine was used to decreases after 7 days in hospital. Combination of Chinese patent medicine and western medicine were mainly for neuroprotective medicine + activate blood and resolve stasis medicine, and anti-platelet medicine + activate blood and resolve stasis medicine, and improve circulation medicine + activate blood and resolve stasis medicine. The phlegm eliminating brain refreshing medicine was mainly combined with neuroprotective medicine by urgent and general admission condition patients, and it was more combined with dehydration medicine by critically admission condition patients. This research found that the dynamic characteristics for the combination of Chinese patent medicine and western medicine of acute phase of ischemic stroke patients by big data analytics and complex networks modeling, and provide basis for acute phase of ischemic stroke patients, it provide basis for ischemic stroke treatment strategy making.

Objective To evaluate the efficacy and safety of pramipexole in treating restless legs syndrome (RLS).Methods A search for randomized,double-blind,and placebo-controlled clinical trials of pramipexole in treating moderate to severe RLS using CNKI,PubMed,Embase and Cochrane Library database was carried out. A meta-analysis of included clinical trials was performed with RevMan 5.0 software.The 2 outcomes that the weighted mean difference(WMD) of change from baseline in International RLS Study Group rating scale(IRLS) score and the relative risk (RR) of response based on the Clinical Global Impression-Improvement (CGI-I) scale score were calculated for efficacy.Safety was assessed with RR of the adverse event (AE).Results A total of 5 clinical trials were included in this meta-analysis,of which 1776 patients were randomly assigned (945 on pramipexole,831 on placebo).The records of patients were pooled.Overall WMD were - 6.34 ( Z =12.76,P < 0.01 ) for the change from baseline in IRLS score,and RR of response based on CGI-I were 1.65 (Z =10.39,P <0.01).The overall RR of pramipexole versus placebo were 1.14 ( Z =1.87,P =0.06 ) for AE.Conclusion To treat RLS,pramipexole is an effective and safe drug.

OBJECTIVE:To analyze and determine the compositions of monosaccharide in polysaccharide from leaves and twigs of Morus nigra from Xinjiang.METHODS:The polysaccharides in leaves and twigs of M.nigra were extracted by water and precipitated by ethanol then hydrolyzed into monosaccharide by using 2 mol?L-1 H2SO4.The monosaccharide was derivatized with 1-phenyl-3-methyl-5-pyrazolone(PMP) and determined by RP-HPLC. RESULTS:The polysaccharide in leaves and twigs of M.nigra were composed of mannose,rhamnose,glucuronic acid,galacturonic acid,glucose,galactose and arabinose etc. All the 7 monosaccharides were well-separated within 25 min. CONCLUSION:The method is simple and sensitive with accurate results,and it can be used for the quality control of leaves and twigs of M.nigra from Xinjiang.
