Esophageal reconstruction is of great importance in the practice of esophagectomy,and esophagogastric anastomosis represents the most essential and key technical aspect of the operation,which largely determined patients' shortterm outcomes.A successful esophageal anastomosis should be no occurrences of postoperative early-stage anastomotic bleeding and leakage and later-stage anastomotic stenosis.The circular stapler,linear cut stapler and hand-sewn anastomosis are the most common anastomotic methods.Hand-sewn anastomosis is the most traditional and classical.Circular stapler has gained significant popularity for its simplicity and convenience.Linear cut stapler used for side-to-side anastomosis has the potential to reduce the risk of postoperative anastomotic stenosis via expanding inner diameter of anastomosis.Every anastomotic method has its advantages and disadvantages,and it cannot completely avoid occurrence of postoperative anastomotic complications.To have a better outcome,both surgeon's experiences and patient's individual conditions should be taken into consideration for the choice of anastomotic technique.

OBJECTIVE: To establish a new method for measuring the content of benzalkonium bromide in disinfectant so- lution METHODS: The sodium nitrite was removed from disinfectant solution by reaction between sodium nitrite and urea to form N2 and CO2 and then benzalkonium bromide in the solution was directly determinated by UV-spectrophotometry with no need of separation RESULTS:There was no significant difference between this method and the method in pharmacopeia CON CLUSION:The method is simple, rapid and accurate and can be used to measure benzalkonium bromide in the solution.

Objective To explore the effect of hypoxia-ischemia(HI)on expression of second mitochondria-derived activator of caspase proteinc(Smac)in brain tissue of neonatal rats.Methods All neonatal rats were divided randomly into HI group,pseudo-operation group,and normal control group.The animal models of HIE were made.At 24,48,72,96 h after HI,Western blot was used to detect the expression of Smac protein in hippocampus.The relative activity of Caspase-3 in hippocampus tissue was determined by colorimetric assay.Results In HI group,at 24,48,72,96 h after HI,the expression levels of Smac protein in hippocampus significantly increased compared with that of pseudo-operation group and normal control group(Pa

Objective To reveal the features of fund sponsored articles and the status of scientific research by analyzing fund sponsored articles in Hubei Region.Methods The papers published from the year of 2001-2010 by the authors of Hubei Region in 11 domestic ophthalmology periodicals were investigated.The amount of funds obtained,funded papers output,research content and direction,and the literature type were calculated by quantitative analysis methods.Results There were 142 of funded projects supported by the National Natural Science Fundation(NSFC),province/ministry and other sourses from the year of 2001 to 2010 in Hubei Region.The amount of projects funded by national was 2.55 times higher in the year between 2006-2010 compared with the year of 2001-2005,meanwhile,province/ministry projects were 1.97 times increased.Among 28698 articles published in 11 ophthalmologic journals(Chinese Journal of Ophthalmology,etc.) between 2001-2010,in which 134 funded articles were published by the authors of Hubei region,accounted for 4.67％ of total papers were supported by varous funds.The papers of applications and basic application were accounted for 43.28％,to explore the pathogenesis and mechanisms were accounted for 30.60％.The subjects of fund sponsored articles were mainly in the field of retine,cornea,glaucoma,lens or cataract.Conclusions Offer as a referance to the ophthalmologist and researchers choose the research direction.Clinical research,continuously research and multidisciplinary cross studies should be strengthed.

Radix et Rhizoma Rhei, the major usage of which is purgation, is widely used in clinical therapy among different prescriptions. According to present reports, researches on herbal compatibility mechanism were mainly fo-cused on the comparison of content changes of active ingredients before and after. In oder to provide references, this review was made on researches of compatibility mechanism of prescriptions and paired drugs for ingredients of Radix et Rhizoma Rhei from research actuality.

To study the influence of the compatibility of ophiopogonis tuber and Chinese magnoliavine fruit with gastrodia rhizome on the pharmacokinetics of gastrodin in rat, three dosages of compound Tianma granule extract (equivalent to gastrodin 50, 100, 200 mg x kg(-1)) and one dosage of Tianma extract (equivalent to gastrodin 100 mg x kg(-1) were administered to rats by intragastric administration separately. Plasma samples were collected at different times and treated with methanol and acetonitrile to precipitate protein. The contents of gastrodin in plasma were determined by HPLC method. The mean plasma concentration-time curves of different medication administration teams were processed with WinNonlin 5.2.1 pharmacokinetic software. The pharmacokinetic parameters of different medication administration teams were analyzed with SPSS statistics 17.0 software. The results indicated that the in vivo kinetic process of gastrodin was fitted to first-order absorption un-compartment model at low, middle dosages and zero-order absorption un-compartment model at high dosage of compound Tianma granule extract. By comparison with the pharmacokinetic parameters of gastrodin (100 mg x kg(-1)) in Tianma extract, the significant decrease for Cmax and significant increase for MRT0-infinity in compound Tianma granule extract indicated that the compatibility of ophiopogonis tuber and Chinese magnoliavine fruit with Gastrodia rhizome can delay the absorption, reduce the elimination rate and prolong the action time of gastrodin in vivo.
