Hilar cholangiocarcinoma (HCCA) or Klatskin tumor is a scirrhous adenocarcinoma that arises from the conjunction of bile duct and hepatic ducts.Hepatic magnetic resonance imaging (MRI) and magnetic resonance cholangiopancreatography (MRCP) are important methods for the diagnosis of HCCA.In this article,the clinical data of 42 patients in the Changhai Hospital and 18 patients in the Eastern Hepatobiliary Surgery Hospital who received MRI and MRCP examination from October 2010 to October 2012 were retrospectively analyzed.According to the pathological features,HCCA could be divided into mass-forming type,infiltrating type and intraductal type.Based on the results of imaging examination and intra-and postoperative pathological examination,Bismuth-Corlette types were decided pre-and postoperatively.The coincidence rate of pre-and postoperative Bismuth-Corlette types was 89.7％ (35/39).Infiltration of liver parenchyma was both detected pre-and postoperatively in 19 patients (16 patients were detected by MRI preoperatively),and the sensitivity of MRI was 84.2％ ; vascular invasion was both detected pre-and postoperatively in 10 patients (12 patients were detected by MRI preoperatively),and the sensitivity of MRI was 83.3％ ; hilar and retroperitoneal lymph node metastasis was both detected pre-and postoperatively in 6 patients (4 patients were detected by MRI preoperatively),and the sensitivity of MRI was 66.7％.Combined application of different sequences and techniques of MRI is helpful in the diagnosis,staging and treatment of HCCA.

Aortic aneurysms appear to have a predilection for the infrarenal aorta. This study is to explain the predilection by using the analysis of wall circumferential tension and stress. 20 healthy persons and 6 infrarenal aortic aneurysm patients were studied. The blood pressures were endoluminally recorded at different sites from the descending aorta to the common iliac artery. The radius of vessel and the thickness of vascular wall were measured by MRI scanning. The wall circumferential tension and stress were calculated. The results showed that the greatest wall stress was at the infrarenal aorta and at the body and exit of aneurysms. Common iliac artery's wall stress was decreased, but greater than thoracic, suprarenal aorta and entrance of aneurysms. These findings suggest that the grent wall circumferential stress may be one cause to make infrenal aorta damageable and be prone to form aneurysms. The increasing stress of the aneurymls exit and common iliac artery′s wall can promote aneurysms to invade distant and common iliac artery.

OBJECTIVE:To investigate the clinical effects of pidotimod in the bronchial asthma complicated with recurrent re-spiratory tract infection,and its effects on immunoglobulin and related indexes. METHODS:A total of 120 bronchial asthma pa-tients with recurrent respiratory tract infection selected from our hospital during Mar. 2011-May 2013 were divided into trial group and control group according to random number table,with 60 cases in each group. Control group received routine corticosteroid therapy,and trial group was additionally given Pidotimod oral solution 0.4 g,po,bid,for 14 d,on the basis of control group. Clinical indexes(the times of respiratory infection,the duration of fever,cough,wheezing attack and antibiotics use),serum in-dexes [β-defensin-1(hBD-1),immunoglobulin A(IgA),IgG,IgM,UREA,ALT],the results of pharynx test before and after treatment,and the occurrence of ADR were observed in 2 groups. RESULTS:Before treatment,there was no statistical signifi-cance in clinical indexes,serum indexes,the results of pharynx test between 2 groups(P>0.05). After treatment,clinical indexes of trial group were significantly lower or shorter then before treatment or control group,while serum levels of hBD-1,IgA and IgG were significantly higher than before treatment or control group,with statistical significance(P<0.05). There was no statistical sig-nificance in clinical indexes and serum indexes of control group,serum levels of IgM,UREA and ALT in trial group before and af-ter treatment(P>0.05). The types and number of pathogenic bacteria of respiratory tract infection were decreased significantly in 2 groups,and the trial group was significantly less then the control group,with statistical significance(P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Pidotimod shows good clinical effects on bronchial asthma complicated with recurrent re-spiratory tract infection,can improve immunity and reduce the types and number of pathogenic bacteria with good safety.

Objective To evaluate the clinical value of three-dimensional contrast-enhanced MR angiography (3D CE-MRA) in the diagnosis and treatment of aortic coarctation. Methods Twenty-one patients with aortic coarctation underwent 3D CE-MRA with a 3D FLASH sequence after injection of 0.2 mmol Gd-DTPA per kg b. w. The source images were subtracted and transferred to computer workstation subsequently post-procession. In six patients, cardioangiography was performed simultaneously. The diagnoses of all patients of them were proven by surgery. Results There were 6 cases (28.6%) of simple type of aortic coarctation and 15 (71.4%) accompanied other cardiovascular abnormalities. 3D CE-MRA could directly demonstrate the stenotic location, degree, extent and extracardiac vascular abnormalities, which accorded with surgical findings. The depiction of the entirety and collateral vessel formation was very helpful for surgery. It can be easier for pre- and post- operative evaluation. Conclusion 3D CE-MRA is a noninvasive and accurate technique in the diagnosis of aortic coarctation. It could replace the cardioangiography for extracardiac vascular abnormalities, and may be one of the first choice examinations.

Objective To investigate pre-and intra-operative preventive measures against immediate conversions to open surgery during laparoscopic cholecystectomy(LC).Methods We retrospectively reviewed 568 cases of LC,27 of which underwent an immediate conversion to open surgery.Causes of conversions,surgical techniques,and curative outcomes were analyzed.Results Causes of immediate conversions included: severe adhesion between the gallbladder and neighboring tissues(1.4%),severe acute cholecystitis(1.1%),freezing adhesion in the Calot triangle(0.9%),large stone obstruction proximal to the gallbladder(0.5%),abnormal anatomy of the cystic duct(0.4%),extensive adhesion around the umbilical port(0.4%),and uncontrollable hemorrhage of the gallbladder bed(0.2%).No fatal cases or intra-and post-operative complications were observed.Conclusions Preventive measures should be taken before and during laparoscopic cholecystectomy to minimize the possibility of immediate conversions to open surgery.

Objective: To explore the values for rejection research of the models through observing rejection rulers following small bowel transplantation(SBT)in Inbred strain rats.Mothods: Heterotopic SBT models were established with Inbred strain F344/RT11 and BN/RT1n by microsurgical technique according to Monchik method,including Isotransplantation(F344→F344,n=8)and allotransplantation(BN→F344, n=8).Results: 1.The mean living time was over 30 days in IT x group ,which was 12 days in AT x group.2.The general conditions have no significant difference on various time points of postoperative day(POD)in IT x group,while pathological features of grafts were concided with diagnosis of nonspecific slight inflammation on POD3 and were the same as the normal grafts on POD 0?5?7 and 9.3.Significant difference of IL-2R? chain and ?-INF mRNA transcription was earlier than pathological feature appearance of rejection.4.The general conditions and pathological features of grafts were concided with diagnosis of mild,moderate and severe actute rejection in AT x group on POD 5?7and 9 respectively.Conclusion:Inbred strain BN to F344 combination is fitter for research on rejection mechanism than F344 to Wistar combination and Outbred strain Wistar to SD combination.
