Objective To investigate the protective effect of mucopolysaccharide polysulfate cream(MPC) and micro needle array drug delivery technologarray(MNADDT) on the blood vessel of arteriovenous fistula.Methods Eighty cases maintenance hemodialysis patients with autogenous arteriovenous fistula were randomly divided into control group(with the treatment of MPC) and study group(with the treatment of MPC plus MNADDT),40 patients in each group.Both groups were studied for the duration of 12 months.The vascular complications of puncture pain sense,puncture failure times,phlebitis,hardening of the arteries,internal fistula stenosis or embolism,pseudoaneurysm,swollen hands comprehensive syndrome of two groups were observed,and the changes of arteriovenous fistula blood flow,blood vessel diameter by Doppler ultrasound were observed in the two groups for 12 months.Results (1)The incidence of puncture pain(2.71±0.11 vs.2.76±0.14,t=2.21,P<0.05),puncture failure times(38 times vs.73 times,χ2=11.425,P<0.05),phlebitis(2 cases vs.8 cases,χ2=4.341,P<0.05) and blood vessel sclerosis(2 cases vs.9 cases,χ2=5.446,P<0.05) of the treatment group were significantly lower than that of the control group during the study(P<0.05).(2)Blood flow of arteriovenous fistulain of control group before and after treatment were (859.7±148.3) ml/min and (946.5±169.2) ml/min respectively,and the difference was significant(t=2.356,P<0.05).While blood flow of arteriovenous fistulain,cephalic vein diameter,head of venous flow velocity of study group before and after treatment were (824.6±171.5) ml/min and (1 218.1±241.9) ml/min,(5.59±0.74) mm and (6.02±0.57) mm,(94.23±27.35) cm/s and (115.85±36.63) cm/s,respectively,and the differences were significant(t=8.212,2.382,2.877,P<0.05),there were no significantly changes in the above indexes in the study group after treatment(t=5.3612,2.152,2.281,P<0.05).Conclusion MPC plus MNADDT can reduce the vascular complications of arteriovenous fistula,improve blood vessel diameter and increase blood flow.

The ongoing health reform is bringing reforms of public hospitals under spotlight in China, attracting growing attention onto its progress and roadblocks. Probing into the "three steps" of public hospital system reform in Wuxi, this article analyzed such a reform in the city. It described the measures and initial outcomes gained in such fields as the hospital trusteeship reform, the separation of hospital regulation from its administration, and the hospital board system. Citing the case of Wuxi No. 2 People's hospital as an example, the authors introduced the innovative efforts made in hospital internal mechanism, management innovation, medical service model, hospital connotation construction, and talents cultivation.

AIM To investigate the effect of DO C(deoxycholic acid) on the absorption of INS-PLA-NP[insulin-loaded poly(lactic acid) nanoparticles] in different sites of gastrointestinal tracts. METHODS After INS-PLA-NP that contained or did not contain DOC was adminitered to different sites in gastrointestianl tracts(stomach, small intestine and colon)of normal rats, the hypoglycemic effect was observed. RESULTS The hypoglycemic effect did not exist after intragastric administration of INS-PLA-NP whether or not DOC was added. The alleviatory hypoglycemic effect was evident after intraintestinal absorption of INS-PLA-NP. After DOC was added, the absorption of INS-PLA-NP was accelerated obviously and the hypoglycemic effect was strengthened significantly. Glucose levels hardly changed after INS-PLA-NP was administered to colon. With the use of DOC, a little hypoglycemic effect appeared. CONCLUSIONS The absorption of INS-PLA-NP in small intestine was accelerated and enhanced by DOC. DOC could be used as absorption enhancer of INS-NP in the future.

The authors probed systematically into the delicacy management measures adopted by the hospital in its internal mechanism reform, innovative medical service model, human resource optimization, and its performance appraisal system reform. Discussions in the paper include such topics as flat management for hospitals,intensification,centralization and integration in diagnose and treatment, as well as vertical nursing management, and the outsourced logistic services. The methods and paths to achieve these goals are summarized as “preciseness, accuracy, carefulness, and strictness”.
