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.

OBJECTIVEThis study observed the curative effect of sustained negative pressure drainage application on treatment of severe maxillofacial and neck space infection.

METHODSIncision and drainage were performed to treat 18 patients with severe maxillofacial and neck space infection. A small incision was made on the site of the most obvious swelling or fluctuations, and localized negative pressure was applied with a drainage device on the wound during suturing.

RESULTSAmong the 18 patients, 14 were healed, whereas 4 underwent dehiscence of the wound after the operation. Negative pressure was lost as the drainage tubes were removed, and non-negative pressure drainage method was used instead. During the negative pressure treatment, swelling and pain did not increase after the operation. Other complications, such as asphyxia, septic shock, or mediastinal abscess, did not occur. All the patients were healed and eventually discharged from the hospital.

CONCLUSIONSustained negative pressure drainage, which is a modified version of the traditional method of incision and drainage, is an alternative treatment for severe maxillofacial and neck space infection. Such treatment reduces patient pain and eases doctor exertion. Thus, this method provides a new therapeutic strategy for severe maxillofacial and neck space infection.

OBJECTIVETo observe the effect of Zhenqing Recipe (ZQR) on non-alcoholic fatty liver (NAFL), and the expression of hepatic salt-inducible kinase 1 (SIK1) and sterol-regulatory element binding protein-ic (SREBP-lc) in type 2 diabetes rats.

METHODSA rat model of type 2 diabetes was established by high fat/sucrose diet combined with intraperitoneal injection of small dose streptozotocin (STZ) . Modeled rats were randomly divided into the model group, the ZQR group, and the metformin group, 8 in each group. Eight rats were recruited as a normal control group. ZQR at the daily dose of 12 g crude drugs/kg was administered to rats in the ZQR group by gastrogavage. Metformin suspension at the daily dose of 150 mg/kg was administered to rats in the metformin group by gastrogavage. Equal volume of distilled water was administered to rats in the normal control group and the model group. All medication lasted for 12 weeks. The levels of fasting blood glucose (FBG), free fatty acid (FFA), serum triglyceride (TG), serum total cholesterol (TC), serum alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were detected. The body weight and wet liver weight were weighed, and the liver weight index calculated. The liver TG content was measured. The pathological changes of liver and the expression of SIK1 were observed by HE staining and immunohistochemistry. The mRNA and protein expression of SIK1 and SREBP-1c were detected using RT-PCR and Western blot.

RESULTSCompared with the normal control group, FBG, FFA, TG, TC, ALT, AST, liver weight index, and liver TG contents significantly increased (P < 0.01); liver steatosis was severe, the mRNA and protein expression of SIK1 obviously decreased (P < 0.01); mRNA and protein expression of SREBP-1c increased (P < 0.01). After drug therapy, compared with the model group, FBG, FFA, TG, TC, ALT, AST, and liver weight index significantly decreased, liver TG contents significantly decreased, the mRNA and protein expression of SIK1 obviously increased, while mRNA and protein expression of SREBP-1c obviously decreased (P < 0.05, P < 0.01) in the ZQR group and the metformin group (P < 0.05, P < 0.01); and the pathological changes were also improved. All the indices were improved more in the ZQR group (all P < 0.05).

CONCLUSIONIn this experiment, we found that the expression of SIK1 decreased in NAFL rats with type 2 diabetes. ZQR could alleviate lesion of NAFL type 2 diabetes rats possibly by up-regulating hepatic SIK1 expression at mRNA and protein levels.
