The article presented the drugs supply management mode reform in place since 2009 in the one district of Shanghai.Authors analyzed and commented the implementation and outcomes,and studied the potentials of successful promotion nationwide.They hold that such a mode works to some extent in terms of reducing management costs of medical institutions,lowering drug purchase price,encouraging rational drug use of such institutions,and reforming the compensation manner for medical institutions.This mode,however,calls for an operating environment in need of not only funding support,but also new concepts and economic development strength of the society as a whole.This means that such a mode is only recommended in developed areas in China.

AIM To evaluate the prevention and treatment of N-(2-mercaptopropionyl)-glycine sodium (MPG-Na) and tiopronin (MPG) on acute liver injury. METHODS The experimental mouse model of hepatotoxicity induced by D-galactosamine (Gal) was applied to investigate preventive and remedial effects. In the preventive experiment, the mice were ip administered with MPG-Na or MPG 37.5,75 and 150 mg·kg~(-1), respectively, for 7 d. Gal 800 mg·kg~(-1) was ip given into the mice 30 min after the last administration. In the remedial experiment, the mice were ip given Gal 800 mg·kg~(-1) and 30 min later followed by MPG-Na or MPG 37.5, 75 and 150 mg·kg~(-1) , respectively, for 2 d. The mice were euthanized and serum was prepared 24 h (pre-treatment) or 48 h (post-treatment) after Gal injection. The activities of serum glutamyl pyruvic transaminase (GPT) and glutamyl oxaloacetic transaminase (GOT), the contents of total protein (TP) and albumin (Alb), and the Alb/globulin (A/G) ratio were determined. The liver tissues were collected for histopathological assessment (HE staining) under light microscope. RESULTS Compared with normal control group, the activities of serum GPT and GOT in model group were significantly increased. The injuries such as fatty degeneration and liver cell necrosis were observed. Compared with model group, the activities of GPT and GOT in pre-treatment groups were obviously decreased in MPG-Na 150 mg·kg~(-1) group. In post-treatment groups, the activity of GPT decreased in 3 MPG-Na groups. The contents of TP, Alb and A/G ratio had little change. In addition, MPG-Na alleviated the injuries such as fatty degeneration and liver cell necrosis obviously. Compared with MPG, MPG-Na showed similar effect. CONCLUSION MPG-Na has an obvious protective effect against Gal-induced acute liver injury in mice and the efficiency is equivalent as MPG.

Objective To investigate the relationship of matrix metalloproteinases(MMP?3 and MMP?9)and the tissue inhibitor TIMP?1 with left ventricular hypertrophy(LVH)in patients with primary hypertension. Methods Totally 140 patients with primary hypertension and 132 healthy controls were included. Matrix metalloproteinase?3(MMP?3),matrix metalloproteinase?9(MMP?9)and tissue inhibitor metalloproteinase?1 (TIMP?1)were measured. All subjects were taken echocardiography examination ,then left ventricular mass index(LVMI)was calculated. Re?sults MMP?3,MMP?9,TIMP?1(488.32±100.32 vs 314.59±99.78;340.56±43.21 vs 290.15±33.98;389.16±57.53 vs 243.45±62.31;P<0.001) and LVMI(113.7±9.9 vs 88.3±10.4,P<0.001)in patients with primary hypertension were significantly higher than those in controls. In a multiple stepwise regression analysis with LVMI as the variable,it was found that age,SBP,MMP?3,MMP?9 and TIMP?1 were main determinants for LVMI (r2=0.78,P<0.001). 3. Patients with primary hypertension were divided into two subgroups according to LVMI,i.e.,hypertension with LVH (group A)and hypertension without LVH(group B). SBP,MMP?3,MMP?9 and TIMP?1(178±31 vs 166±25;490.14±99.13 vs 405.56±53.12;340.56±43.21 vs 290.15±33.98;393.45±47.69 vs 301.58±39.57;P<0.05)of group A were significantly higher than those of group B. Conclusion MMP?3,MMP?9 and TIMP?1 are influencing factors for LVH in patients with primary hypertension.

Objective To explore the application value of plastic biliary stent and fully covered self-expandable metallic stent (FCSEMS) in endoscopic retrograde cholangio pancreatography (ERCP) for treatment of benign biliary stricture after liver transplantation.Methods The retrospective cross-sectional study was conducted.The clinical data of 54 patients with benign biliary stricture after liver transplantation undergoing ERCP treatment who were admitted to the First Affiliated Hospital of Xi'an Jiaotong University between January 2010 and August 2016 were collected.Among 54 patients,44 had simple anastomotic stricture and 10 had non-anastomotic stricture.All the patients underwent stent implantation by ERCP.Patients with stricture within 1 month postoperatively initially selected single plastic stent or endoscopic nasobiliary drainage (ENBD),and then changed into multiple plastic stents at the second stent replacement.Patients with stricture after 1 month postoperatively selected multiple plastic stents,multiple plastic stents after balloon dilation or FCSEMS.Observation indicators:ERCP situations,stent implantation,time of stent indwelling,postoperative complications,stent dislocation,treatment outcome and follow-up situations.Patients were followed up by outpatient examination and telephone interview up to November 2016.Clinical symptoms of patients were observed within 1 month postoperatively and liver function and abdominal ultrasound were retested.Liver function and remission degree of biliary stricture were monitored regularly once every 3 months.Measurement data were described as average (range).Results All the patients underwent successful ERCP,of which 53 completed the process of ERCP and 1 rejected treatment due to economic problems.All the 54 patients received 140 times ERCPs with an average of 2.59 times per person,21 times ENBDs,11 times FCSEMSs and 108 times plastic stent implantations (including 35 times single stent implantations,46 times double stents implantations,23 times 3-stents implantations and 4 times 4-stents implantations).All the 54 patients were followed up for 3-143 months,with an average time of 73 months.Of 44 with anastomotic stricture,34 received plastic stent implantation and 98 times ERCPs,with an average number of stent implantation of 2 (range,1-4) and an average time of stent indwelling of 10.7 months (range,9.0-13.0months);the postoperative acute pancreatitis,biliary infection,hyperamylasemia and adverse stent implantation or dislocation were detected in 4 persons every time,7 persons every time,10 persons every time and 3 persons every time,respectively;26 patients were cured and 5 were improved,with an effective rate of 91.2% (31/34);3 patients with noneffective treatment continued to undergo ERCP and 3 patients had recurrence of anastomotic stricture.Among 10 patients with initial FCSEMS implantation,12 times ERCPs were performed,with an average time of stent indwelling of 7.6 months (range,6.0-12.0 months);postoperative biliary infection,hyperamylasemia and stent dislocation were detected in 1 person every time,1 person every time and 1 person every time,respectively;8 patients were cured,with an effective rate of 8/10;of 2 patients with persistent stricture,1 patient received contrast examination after stent removal,showing a comparative stricture in level 1 branch of intrahepatic duct and considering combined ischaemia,and then underwent the second implantation using multiple plastic stents;the other patient had elevated level of jaundice at 3 months after stents removal and received ERCP,showing anastomotic inflammatory polyp,and then underwent FCSEMS implantation again.Ten patients with non-anastomotic stricture received plastic stent implantation and 30 times ERCPs,with an average number of stent implantation of 3 (range,2-4) and an average time of stent indwelling of 11.3 months (range,10.0-14.0 months);the postoperative acute pancreatitis,biliary infection,hyperamylasemia and adverse stent implantation or dislocation were detected in 2 persons every time,5 persons every time,2 persons every time and 1 person every time,respectively;3 patients were cured and 3 were improved,with an effective rate of 6/10;of 4 patients with noneffective treatment,2 died of gradually deteriorating liver function and 2 underwent the second liver transplantation.Conclusions Stent implantation in ERCP is safe and effective for treatment of benign biliary stricture after liver transplantation,single plastic stent should be used in the early period (within 1 month) and multiple plastic stents should be used in the later period.Although FCSEMS has a higher displacement rate,it should be recommended due to a better clinical effect,lower incidence of complications and simple operation.For patients with non-anastomotic stricture,plastic stent should be used for extrahepatic biliary stricture,with a good clinical effect,and there is worse effect in stent implantation through ERCP for multiple intrahepatic biliary strictures.
