Objective To investigate the protective effect of fructose 1,6-diphosphate (FDP) on the brain against ischemia-reperfusion (I/R) injury and the possible mechanism. Methods One hundred and eighty SD rats weighing 275-325 g were randomly divided into 3 groups (n = 60 each): Ⅰ gham operation group; Ⅱ I/R group and Ⅲ FDP group. Global cerebral I/R was produced by 4-vessel technique. Bilateral vertebral arteries were coagulated and bilateral common carotid arteries were occluded for 5 min and then released for reperfusion. In sham operation the four vessels were exposed but not occluded. In FDP group FDP 1.5 mg?kg-1 was given Ⅳ when reperfusion was started, while in sham-operation group and I/R group normal saline (NS) 1.5 ml?kg-1 was given Ⅳ instead of FDP. The animals were killed at 2, 6, 12, 24, 48 and 72 h of reperfusion ( n = 5 each) for determination of cerebral SOD activity and MDA contents, the number of apoptotic neurons (TUNEL) and expression of P38 and Ref-1 in the brain (immuno-histochemical method) .Results The MDA content was significantly higher whereas the SOD activity and P38 and Ref-1 expression were significantly lower at all time points in I/R group than in sham operation group ( P

Objective To study the feasibility and effect of implantation of the biliary stent for treatment of biliary obstruction.Methods A retrospective analysis of the diagnostic and therapeutic procedure was done in 131 cases of the inpatients from Apr.2006 to Feb.2007.The 131 patients with biliary obstruction underwent successfully 138 cases/times implantation of biliary stent.The results of recession of jaudince and the rate of complication were evaluated.Results All patients were implanted biliary stent successfully.The serum total bilirubin,direct bilirubin,alkaline phosphatase,?-glutamyl transpeptidase decreased obviously in three days,and the difference was remarkable.The main complication was infection of biliary tract and pancreatitis.Conclusion Implantation of biliary stent is an effective management for biliary obstruction,especially for patients who have lost the chance of operation.

Objective To evaluate the application effect of modular management in technique and nursing of department of radiology. Methods 7 modules were divided: administrative management, quality management, equipment management, environment and emergency management, material cost management, education management and scientific research management. Each module was responsible for specially-assigned person reporting daily circumstance. Results After more than a year, 16 technical professionals, 8 educational professionals, 10 research professionals and 7 technicians were cultivated, 12 key performance indicators (KPI value) increased steadily were set up. Conclusions Modular management provided a novel concept for technique and medical care management of radiology department. Our practice suggests that modular management is alternative for development of technique and medical care in radiology department. Further research and application are needed.

Objective To analyze the identification and antibiotic resistance of non active Escherichia coli isolated from feces . Methods Clinical fecal specimens were collected from January 2013 to June 2015 for bacterial culture ,identification and antimicro-bial susceptibility testing .Results Sixty-one strains of E .coli ,inactive were detected ,18 strains of which could be agglutinated with diagnostic serum of Shigella .Three stains could produce extented spectrum β-lactamases(ESBLs);The rate of antibiotic resistance of amoxicillin and ticarcillin was 100% ,The rate of piperacillin ,cephalothin and sulfamethoxazole was 78% ,the rate of cefoxitin and amikacin was 33% ,the rate of piperacillin/tazobactam ,imipenem and meropenem was 0% .Conclusion Non active Escherichia coli can induce diarrhea ,which is easily misdiagnosed as Shigella ,the antimicrobial resistance between Escherichia coli and non active Escherichia coli is not significant difference .

Objective: The inhibition on the proliferation of colorectal carcinoma cell strain with different proliferative potential by ATRA was investigated in present study, which would benefit for the therapy of ATRA on colorectal carcinoma. Methods: The proliferation of LS174T and CW-2 colorectal carcinoma cell strain inhibited by ATRA was determined using cell observation, FACS and MTT methods. Results: The growth speed of LS174T cell strain was faster than that of CW-2. ATRA played a significant role on inhibiting the proliferation of LS174T and CW-2 cell strain and inducting the cell differetiation in vitro. Conclusions: ATRA could inhibit the growth of LS174T and CW-2 cell strain. ATRA could inhibit the proliferation of colorectal carcinoma cell and induce cell differentiation to some extent, which was correlated with the concentration of ATRA.

[Objective] To research the sedative effect of intranasal dexmedetomidine and sufentanil for pediatric sedation for stomatological operation of outpatient department.[Methods] 60 children undergoing stomatological operation of outpatient department,age 3 ～ 7 years,weighing 10 ～ 32 kg,of ASA physical status Ⅰ ～ Ⅱ,were divided into the three groups (n =20) randomly using a random number table:group dexmedetomidine and sufentanil (group DS),group dexmetomidine (group D),group sufentanil (group S).Recorded the children's behavior using the Ohio State University behavior rating score (OSUBRS),the University of Michigan Sedation Score (UMSS),SBP,HR and side-effects when entry,during and leave operation and in post-anesthesia care unit,side-effects,the satisfaction of stomatological doctors and parents.[Results] The OSUBRS of group DS when entry,during operation were lower than group D (P ＜ 0.01).The UMSS of group DS were higher than group D and group S when entry and during operation (P ＜ 0.05).The success rate of group DS was higher than group D and group S (P ＜ 0.01).There was no different of mean percentage change in systolic blood pressure and heart rate from baseline between group DS and group D (P ＞ 0.05).There were no instances of respiratory depression,hypotension and bradycadia.[Conclusion] Intranasal dexmedetomidine and sufentanil provides satisfactory pediatric sedation for stomatological operation of outpatient department without side effects such as respiratory depression,bradycadia and hypotension.

Objective To probe into the effect of sitagliptin on blood glucose fluctuation of the patients with type 2 diabetes mellitus(T2DM) and poor control by insulin aspart 30.Methods Ninety cases of T2DM and poor control by insulin aspart 30 in affiliated Zhongshan hospital from January 1,2014 to December 31,2014 were selected and randomly divided into three groups:simply continuous subcutaneous insulin injection(CSII),acarbose combined CSII group(CSII + Aca) and sitagliptincombined CSII group (CSII + Sig),30 cases in each group.Three groups received the intensive treatment for 2 weeks,and72-h continuous glucose monitoring was performed on last 3 d.The 24 h mean blood glucose(24 hMBG),largest amplitude of glycemic fluctuation(LAGE),mean amplitude of glycemic excursion(MAGE) within 1 d,postprandial blood glucose spike(PGS),postprandial glucose peak time(△t),postprandial glucose excursion(PPGE) and total T were observed within 24 h.The difference of insulin dose(△ insulin),hypoglycemia incidence,glucose-target rate,blood glucose profiles were compared at the end of treatment.Results After two-week treatment,intraday blood glucose variation indicators(24 hMBG,LAGE and MAGE) and postprandial blood glucose variation indicators (PGS,△t,PPGE and total T) in the CSII+Sig and CSII+-Aca groups were significantly lower than those in the CSII group(P＜ 0.05),while the differences in blood glucose variation indicators between the CSII+Sig group and CSII+-Aca group were not statistical significant(P＞ 0.05).In the comparison after treatment,△ insulin,hypoglycemia incidence and glucose-target rate in the CSI + Sig group were lower(P＜0.05).Conclusion The combined application of short-term CSII and sitagliptin will achieve a better effect than the combination with acarbose,can smoothly and steadily reduces the blood glucose level,relieves the whole day glucose fluctuations,effectively reduces △ insulin,and has lower hypoglycemia occurrence rate.
