Objective To study the role of endoscopic retrograde cholangiopancreatography (ERCP) in diagnosing and treating iatrogenic bile duct injury after laparoscopic cholecystectomy (LC).Methods A retrospective study was conducted on 45 patients with iatrogenic bile duct injury after LC who were investigated and treated by ERCP from December 2002 to August 2015.Results Using the StrasbergBismuth classification,there were 14 patients with type A and 4 with type C who were managed successfully using endoscopic nasobiliary drainage (ENBD) and interventional ultrasound abdominal localized puncture and drainage ; 7 patients with type D were managed successfully using endoscopic sphincterotomy (EST) and endoscopic retrograde biliary drainage (ERBD).For the 5 patients with type E Ⅰ and 3 patients with type E Ⅱ who were treated by EST and ERBD,one patient who had common bile duct transection required cholangioenteric Roux-en-Y anastomosis.For the 6 patients with type E Ⅲ and 6 patients with type EⅣ who were treated by EST and ERBD,a patient required a cholangioenteric Roux-en-Y anastomosis to achieve good results.Conclusions When iatrogenic bile duct injury is suspected after LC,correct assessment with ERCP should be taken immediately.ERCP when combined with ENBD and (or) ERBD could reduce bile duct pressure and dilate stenotic bile ducts to avoid further operation.

Objective To study the relationship between serum iron, serum ferritin and alcoholic fatty liver(AFL), nonalcoholic fatty liver(NFAL). Methods The liver specimens of 97 patients with fatty liver were obtained by 1 second liver biopsy, and were further stained by haematoxylin eosin(HE) and Perl's Prussian. Meanwhile the serum levels of iron and ferritin were detected by atomic absorption spectrum and radioimmunoassay respectively. Results Compare to the control group ((10.5?5.7)?mol/L, (143.3?71.9)ng/ml),the serum levels of iron and ferritin were obviously high in patients with severe NAFL ((21.5 ?11.1 ) ?mol/L , (199.3?72.1)ng/ml) or moderate AFL((20.9? 9.3 )?mol/L,(217.6.0?71.8)ng/ml) and severe AFL ((29.1?6.5) ?mol/L ,(284.7?77.9)ng/ml) ( P

ObjectiveTo observe the clinical effect of Kangxiuke apozem in the treatment of severe bum shock.Methods40 patients of severe burn shock were randomly divided into a treatment group and a control group,with 20 patients in each group.All the patients were treated by the same route of counter-shock therapy,and the treatment group was additionally given Kangxiuke apozem (nasal feeding,qd,150 ml/d).Level of blood lactic acid,heart rate and urinary volume were evaluated by time.Main shock symptoms,including restlessness,hydrodipsia,perspiration and coldness,were observed.ResultsThe treatment group was significantly superior to the control group in the amelioration of blood lactic acid,heart rate and urinary volume ( t =10.485、3.219、7.429,P＜ 0.01 ).The symptomatic extinction of restlessness,hydrodipsia,perspiration and coldness in the extremities in the treatment group were significantly superior to those in the control group (x2=10.16、7.37、5.63、4.29,P＜0.05).ConclusionAt the same time of routine counter-shock therapy,thereby prompt burn patients to smoothly go through shock period and decreas late complications.

Objective To investigate the differentiation of neuroendocrine component (NEC) in colorectal adenocarcinoma in relation to its significance by comparing the outcome between patients with or without NEC.Methods The paraffin sections from patients with pathologically confirmed colorectal adenocarcinoma were retrospectively collected and screened for those with NEC by morphological examination and immunohistochemistry with neuroendocrine markers.Control patients (n=54) without NEC were selected from colorectal cancer database and 2: 1 matched on the basis of clinical features with NEC positive patients (n=27).Relative analysis was performed between two groups.Results With a median follow-up of 72 months,the 5-year disease free survival was 58.0% (16/27) in NEC positive group and 79.1% (43/54) in control group (P=0.036).Similarly,the 5-year cancer-specific overall survival was significantly lower in NEC positive group than in control group (58.3% versus 81.1%,P=0.037).Cox regression showed that the 5-year cumulative risks of disease recurrence and cancer-caused death in NEC positive patients were 2.38 and 2.41 times higher than those in control patients,respectively.Conclusions NEC appears to bear a poor prognosis in patients with colorectal adenocarcinoma.

In order to explore the role of acetylcholine in the pathogenesis of Parkinson's disease (PD), the changes in the concentration of acetylcholine (Ach) in the striatum, the apoptosis of substantia nigra cells, the ultrastructure and the changes of Nissl cells in rats during the morbidity of PD, and the corresponding behaviors in rats with PD were observed. Rat PD model was established by using the modified Thomas method. Eighty-one rats were randomly divided into normal control, sham operation and PD groups and their behavior features were observed at post-operative day (POD) 7, 14 and 21 as three subgroups (n=9 each). The concentration of Ach in the striatum was determined by using high-performance liquid chromatography. The apoptosis of substantia nigra cells was assayed by using TUNEL method. The ultrastructural changes in the substantia nigra were observed under the electron microscopy, and the survival of neurons in the substantia nigra area was examined by using Nissl staining. In PD group at POD 7 to 21, the damage in the substantia nigra area was gradually aggravated, the concentration of Ach, apoptosis rate and turns of rotation were gradually increased, and the number of Nissl cells was gradually reduced over the time as compared with the normal control and sham operation groups (all P<0.05). It was concluded that there exist dynamic changes in Ach concentration, ethology and apoptosis of the substantia nigra cells during the morbidity of PD, suggesting the contribution of apoptosis to the morbidity of PD, and critical role of Ach in the pathogenesis of PD.

Objective To assess the impact of additional cycles of temozolomide on the survival of glio-blastoma(GBM)patients after 6 months of maintenance temozolomide(TMZ)following concurrent TMZ chemo-therapy and radiation therapy. Methods Data of 51 GBM patients from 2009 to 2015 were retrospectively studied and the therapeutic effect was assessed according to whether receiving long-term treatment with TMZ. Results Sev-enteen of fifty-one GBM patients received 8 or more cycles and prolonged treatment improved progression-free sur-vival(P=0.011)and overall survival(P=0.004). Conclusions Extended use of TMZ is safe to GBM patients , which may improve response OS and PFS compared to conventional regimen. Prospective studies in larger popula-tions are needed to better-define the population to whom it can be proposed and its optimal duration.
