Introduction: Gallstones disease is a common disorder and symptomatic disease is usually managed with surgery while those with common bile duct stones are usually managed with endoscopic intervention before proceeding to surgery. This study was intended to assess the rate of cholecystectomy among patients who had undergone ERC interventions, the reasons for not proceeding to cholecystectomy and related complications. Materials and Methods: Patients who had intact gallbladder and had undergone ERC for stones related complications over a two year period were retrospectively identified from the Endoscopic Unit Registry. Detailed case note reviews were conducted. Results: The overall cholecystectomy rate post-ERC interventions was 36.9% (48/130). Cholecystectomy was offered to 59.2% (n=77) and the uptake was only 58.4% (n=45/77). Among those who agreed for cholecystectomy, 11.1% (n=5/45) failed to turn up for their scheduled surgery. Three patients (6.7%) had symptoms recurrence before their scheduled surgery: two subsequently underwent cholecystectomy without ERC intervention and one who was pregnant was managed conservatively with holecystectomy. Among the patients who had declined cholecystectomy, 18.8% (n=6/32) had symptoms recurrence. Four patients required repeat ERC interventions and eventually all had cholecystectomy subsequently. The most common reason for declining cholecystectomy was 'not keen' and already asymptomatic (46.9%, n=15/32). Among patients who were not offerred cholecystectomy (n=53/130), symptoms recurrence occurred in 15.2% (n=7/53). Four patients required repeat ERC interventions and three subsequently underwent cholecystectomy. Conclusions: The cholecystectomy rate remains low after ERC interventions. Recurrence of symptoms necessating re-interventions occurred in patients offerred and not offerred cholecystectomy. The uptake rate should be improved and delay to cholecystectomy should be reduced to avoid symptoms recurrence. Patients not undergoing interventions should be advised regarding symptoms recurrence and should be monitored.

Abstract: To report the diagnosis and treatment of Mucor infection in two cases of renal transplantation, and to provide reference for diagnosis and treatment of Mucor infection. Case 1, a male patient, who underwent allogeneic kidney transplantation due to increased creatinine for more than 8 years. The renal function had partially recovered 25 days after the operation, but then the patient suddenly got worse epigastric pain. Pathogen culture, smear microscopy, mass spectrometry identification and next-generation metagenomic sequencing (mNGS) were performed on the peritoneal drainage, with the result pointing to Rhizopus microsporus. The patient's condition improved after antifungal treatment using amphotericin B lipid complex (ABLC) and was discharged. Case 2, a male patient with hypertension and increased creatinine for more than 7 years was admitted to the hospital. After allograft kidney transplantation, tissue culture smear and histopathological examination suggested Mucor infection. The patient then underwent a "hand muscle debridement surgery + closed negative pressure drainage (VSD)" procedure, and amphotericin B was given postoperative treatment against Mucor infection and debridement. Subsequent retesting with mNGS showed no signs of Mucor infection. In the course of treatment, two patients developed abdominal pain after treatment with tegacycline, which was immediately diagnosed as pancreatitis and recovered after withdrawal. Both patients being male, with one case associated with hypertension. After initially guiding the diagnosis with traditional smear tests, final confirmation was done using histopathological examination, mNGS and mass spectrometry. One case was infected by Rhizopus microspora, and the other was infected by Rhizopus oryzae and Cunninghamia microbicans. The causes leading to Mucor infection in patients post renal transplantation varied greatly. Early diagnosis is the key to treatment of patients with Mucor infection after renal transplantation. Treatment with amphoteric B and its liposome is an effective means to improve mucormycosis patients after renal transplantation. The use of amphotericin B lipid complex treatment proved to be an effective treatment method for patients with Mucor infection after renal transplantation.

0.05).The death rate of cases with pneumonia combined with ascites was higher than that of cases with ascites only(?2=4.894,P=0.027) and cases without ascites and infections(?2=9.260,P=0.002).Unfavorable prognosis was found in cases with Enterococcus faecium isolated before OLT.CONCLUSIONS Severe lung infection before OLT is one of the main reasons of death.It is important to grasp characteristics of infection,evaluate risk fully,control infections and screen cases strictly before OLT to improve survival rate.

Objective To evaluate different expressions of high mobility group box 1(HMGB1)and receptor for advanced glycation end products(RAGE)in placentas and their relationship with preeclampsia.Methods Fifteen early-onset pre-eclaraptic women(early-onset pre-eclampsia group),22 late-onset pre-eclamptic women(late-onset pre-eclampsia group)and 12 normotensive women(control group)in the third trimester were recruited at the Shengjing Hospital of China Medical University from March 2006 to March 2007.The localization and levels of HMGB1 and RAGE in placentas of the three groups were detected by the strept avidin biotin-peroxidose method.Results (1)Immunoreactivities to HMGB1:positive immnnostaining for HMGB1 was observed in trophoblast,macrophages,decidual cells,vascular muscle cells,endothelial cells and placental mesenchymal cells in the placentas from the pre-eclamptic women,while a low level of immunoreactivities was observed in the placentas from healthy pregnancies;the staining was observed within both the nuclei and the cytoplasm,mainly in the cytoplasm.The cytotrophoblast,especially the nuclei was extensively positive for HMGB1 in early-onset pre-eclampsia. (2)Immunoreactivities to RAGE:positive immunostaining for HMGB1 was observed in syncytiotrophoblast,macrophages and endothelial cells in the placentas from the preeclamptic women,while a low level of immunoreactivities was observed in the placentas from healthy pregnancies:the staining was in the cytoplasm and(or)cell membrane.The trophoblast was extensively positive for RAGE in early-onset pre-eclampsia.(3)Positive rate of HMGB1 expression:the expression of HMGB1 in early-onset group(73%,11/15)and late-onset group(64%,14/22)was significantly higher than that in normal group(17%,2/12;P<0.05),but no significant difference was found in early-onset group and late-onset group(P>0.05).(4)Positive rate of RAGE expression:the expression of RAGE in early-onset group(80%,12/15)and late-onset group (82%,18/22)was significantly higher than that in normal group(25%,3/12;P<0.05),but no significant difference was found in early-onset group and late-onset group(P>0.05).Conclusions The increased expression of HMGB1 and RACE in the placenta may play an important role in the pathogenesis of pre-eclampsis.The different locations may be associated with the occurrence of different onset types of pre-eclampsia.
