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.

Objective To study the clinical application of laparoscopy in the treatment of closed abdominal trauma. Methods Emergent laparoscopic exploration and treatment was conducted in 21 patients with closed abdominal trauma, who had stable hemodynamic parameters,from July 2000 to December 2003. Results Diagnosis was clarified laparoscopically in all the 21 patients. There were 4 cases of open liver repair, 2 cases of laparoscopic liver repair, 5 cases of open splenectomy, 3 cases of hand-assisted laparoscopic splenectomy, 2 cases of video-assisted small incisional intestinal repair, 4 cases of partial intestinal resection and 1 case of laparoscopic greater omentum hemostasis. Conclusions Laparoscopy in the diagnosis and treatment of closed abdominal trauma is accurate, safe and effective.

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 investigate the level and proportional relationship of free fluorine and soluble fluoride in different brands of toothpaste,and analyze possible risk factors.Methods A total of 54 samples of commercially available toothpastes of domestic,joint venture and imported in Guiyang City were collected,and the levels of free fluoride and soluble fluorine were determined,respectively,using fluorideion selective electrode.method (GB 8372-2008).Results The number of the toothpaste was 32,12,10,respectively,in domestic,joint venture and imported.The levels of free fluorine ranged from 0.98 to 1 603.50 mg/kg,3.22 to 617.50 mg/kg and 306.80 to 1 590.80 mg/kg,respectively,in toothpastes of domestic,joint venture and imported; the number of exceeding the standard free fluorine was 3,0 and 1,respectively,in toothpastes of domestic,joint venture and imported; the rate of exceeding the standard free fluorine was 9.4％,0.0％ and 10.0％,respectively,in toothpastes of domestic,joint venture and imported.The levels of soluble fluorine ranged from 3.06 to 4 302.50 mg/kg,9.02 to 1 667.30 mg/kg and 9.18 to 4 013.20 mg/kg,respectively,in toothpastes of domestic,joint venture and imported; the number of exceeding the standard soluble fluorine was 9,2 and 3,respectively,in toothpastes of domestic,joint venture and imported; the rate of exceeding the standard soluble fluorine was 34.4％,16.7％ and 30.0％,respectively,in toothpastes of domestic,joint venture and imported.The proportion of free fluorine and soluble fluoride was:domestic 1.0 ∶ 2.7,joint venture 1.0 ∶ 2.7,imported 1.0 ∶ 2.5,respectively.The confidence limit (R/d) was 0.98.Conclusion The fluoride level in different brands of toothpaste has exceeded the standard,the content and proportion of soluble fluoride are obviously higher than those of free fluoride,and there is a risk on tooth damage from fluoride,and factories should strengthen quality control in adding fluoride.

Objective To evaluate the survival benefit of amphotericin B (AmB) plus flucytosine or fluconazole for treatment of patients with acquired immunodeficiency syndrome (AIDS)-associated cryptococcal meningitis.Methods The following database were searched from the beginning to October 2013,including Cochrane library,PubMed,OVID,Embase,Wanfang Date,CNKI and Chinese Biomedical Database,and the references of eligible studies were manually screened.Reference lists of relevant articles were screened according to selection and extraction criteria.Meta-analysis was performed using RevMan 5.2.Results Four prospective controlled studies with a total of 399 patients with cryptococcal meningitis were identified,including 386 patients with AIDS-associated cryptococcal meningitis and 13 human immunodeficiency virus (HIV)-negative patients.Two hundred and twentyseven patients were treated with AmB and flucytosine combination therapy,including 217 patients with AIDS-associated cryptococcal meningitis and 10 HIV-negative patients.One hundred and seventy-two patients were treated with AmB and fluconazole combination therapy,including 169 patients with AIDS-associated cryptococcal meningitis and 3 HIV-negative patients.The Meta-analysis revealed that the mortality rate in AmB plus flucytosine combination therapy group was 6.6％ (95％ CI:18.5％-31.6 ％) at two weeks point,which was significantly lower than that in AmB plus fluconazole combination group (19.7％,95％CI:-23.6％-62.9％; OR=0.51,95％CI:0.27-0.93,P＜0.05).But at 10 weeks point,the mortality rate in flucytosine combination group was 12.9％ (95％oo CI:-22.2％-48.0％),which was lower than that in fluconazole combination group (31.4％,95％ CI:-23.1％-85.9 ％).However,there was no statistically significant difference between these two groups at 10 weeks point (OR=0.70,95％CI:0.44-1.13,P=0.15).Conclusion Administration of AmB plus flucytosine at early stage can reduce the mortality rate in patients with AIDS-associated cryptococcal meningitis.

Objective To define a suitable threshold setting for gross tumor volume (GTV)when using 18F-fluoro-deoxyglucose positron emission tomography and computed tomogram (PET/CT) for radiotherapy planning in Nasopharyngeal carcinoma(NPC).Methods Sixteen NPC patients respectively received PET/CT and MRI scan before their radiation treatment.All of the images were transferred to the radiotherapy planning system (TPS).MRI/CT-based primary GTV was defined as GTVf.Biological target volumes (BTVs) were derived from PET/CT-based GTVs of primary tumors.The BTVs were defined as the volumes when adjusting different percentage of the maximal standardized uptake value (SUVmax).GTVfs were compared with BTVs.The suitable threshold level (sTL) could be determined when BTV value and its morphology using a certain threshold level were observed to be the fittest GTVf.The suitable standardized uptake value (sSUV) was calculated as the sTL multiplied by the SUVmax.Results Our result demonstrated no single sTL or sSUV method could achieve an optimized volumetric match with the GTVf.The sTL was [20.93％±6.51％(15％-40％)],whereas the sSUV was [2.27±0.48(1.56-3.25)].The sTL was inversely correlated with the SUVmax sTL =-0.144ln(SUVmax) + 0.5548 (R2 =0.85,F =78.57,P＜0.01.The sSUV showed a linear correlation with the SUVmax sSUV =0.104(SUVmax) + 1.0398,(R2=0.75,F=41.88,P＜0.01).The sTL was not associated with the value of GTVf.Conclusions In PET/CT-based BTV for NPC,SUVmax threshold method is feasible.sTL is not a fixed value,which is correlated with the SUVmax instead of the value of tumor.
