Integration of heterogeneous systems is the key to hospital information construction due to complexity of the healthcare environment. Currently, during the process of healthcare information system integration, people participating in integration project usually communicate by free-format document, which impairs the efficiency and adaptability of integration. A method utilizing business process model and notation (BPMN) to model integration requirement and automatically transforming it to executable integration configuration was proposed in this paper. Based on the method, a tool was developed to model integration requirement and transform it to integration configuration. In addition, an integration case in radiology scenario was used to verify the method.

Background and purpose: Because of the aggressive nature of hilar cholangiocarcinoma and the absence of effective adjuvant therapy, surgical radical resection offers hilar cholangiocarcinoma patients the only choice. Research focus include preoperative assessment, the use of preoperative biliary drainage, the range of hepatic resection, and the range of lymphadenectomy. To investigate the clinical experience and efifcacy of combined hepatectomy in the treatment of hilar cholangiocarcinoma. Methods: Two hundred and seven patients with hilar cholangiocarcinoma treated surgically in the First Afifliated Hospital of Kunming Medical University form Jan. 2007 to Oct. 2013 were retrospectively analyzed. Results:Of the 207 patients, 125 patients who received radical resection (R0 resection) and the curative resection rate was 60.4%. One hundred and iffty-six cases were treated in combined hepatectomy group, 51 cases in non-hepatectomy group, the rate of R0 resection was 70.5%in hepatectomy group and 29.4%in non-hepatectomy group, and the difference was signiifcant (P<0.01). Two patients died perioperatively, the main postoperative complications included hepatic function insufifciency and bile leakage. One hundred and seventy-two patients were followed up, the median survival time of the 102 patients who received R0 resection was 45 months, and the 1, 3, 5 year survival rates were 96.1%, 59.1%and 17.2%. The median survival time of the 70 patients who received R1-2 resection was 26 months, and the 1, 3 year survival rates were 81.3%and 19.2%, and none of the patient survived for over 5 years. The survival rate of patients who received R0 resection was signiifcantly higher than those who received R1-2 resection (χ2=39.121, P<0.01). In the hepatectomy group was awarded the R0 resection in patients with postoperative 1, 3, 5 year survival rate was 97.8%, 63.9% and 18.0%, in non-hepatectomy group received R0 resection in patients with postoperative 1, 3, 5 year survival rate was 83.3%, 20.8%and 8.3%. There were signiifcant differences in the postoperative survival rate between both group (χ2=5.988, P=0.014). Conclusion:Radical excision is the key to improve the long term survival. Combined hemihepatectomy and standardized lymph node resection has signiifcantly improved the radical resection rate and the efifcacy of treatment for hilar cholangiocarcinoma.

Purpose To study the value of contrast-enhanced ultrasound (CEUS) quantitative technique in evaluating the perfusion of hepatic microcirculation in acute hemorrhagic shock (HS),and to investigate the value of CEUS quantitative analysis in HS diagnosis and treatment.Materials and Methods Sixty healthy adult New Zealand white rabbits of either gender were randomly divided into three groups for establishing mild,moderate and severe HS models,respectively.Before modeling and 30 min after stable modeling,liver CEUS examination was performed,and the original images were stored.Blood test of lactic acid,liver function,and liver biopsy for pathological examination were conducted after CEUS.Finally,the arrival time (AT),time to peak (TTP),rising time (RT),peak intensity (PI) and area under the curve (AUC) were analyzed offiine.Results Compared with pre-modeling,AUC decreased in mild HS group (P＜0.05);TTP and RT were delayed,but PI and AUC decreased in moderate and severe HS groups (all P＜0.05);AT was delayed in severe HS group (P＜0.05).The differences of TTP,RT,PI and AUC between the groups of mild,moderate and severe HS were significant (P＜0.05).Compared with pre-modeling,lactic acid in three HS groups increased significantly,the liver function indexes were changed to different degrees,and the degree of liver cell pathological changes was closely related to the degree of HS.Conclusion CEUS can quantitatively evaluate the changes of hepatic microcirculation induced by HS at different degrees.

Purpose To investigate the value of contrast-enhanced ultrasound (CEUS) in monitoring hepatic parenchymal perfusion quantitatively during resuscitation after hemorrhagic shock (HS).Materials and Methods Forty-five labeled rabbits were randomly divided into five groups.One group was normal control group,and the other four groups were established reversible HS modes by using modified Wiggers method.In the four model groups,one group was chosen as the shock group,and the other three groups received colloid (hydroxyethyl starch) for resuscitation.The three resuscitation groups were named as 1 h group,4 h group,24 h group according to resuscitation time.The arterial blood was collected for testing blood lactic acid (LAC) in each group.The CEUS was performed to form time-intensity curve (TIC) for quantitative analysis.At the end of the experiment,the rabbits were sacrificed and the liver tissues were examined for pathology.Results Compared with the normal control group,the arrival time (AT) and time to peak (TTP) of the shock group were significantly prolonged,and the peak intensity (PI) and area under curve (AUC) of the shock group decreased,all with significant difference (all P＜0.05);in the 1 h resuscitation group,the PI and AUC increased,and the AT decreased,all with significant difference (all P＜0.05);in the 4 h and 24 h resuscitation group,the PI and AUC increased,and the AT and TTP decreased,but all without significant difference (all P＞0.05).Compared with the shock group,the PI and AUC of the 1 h resuscitation group increased,and the AT of 1 h resuscitation group decreased,all with significant difference (all P＜0.05);all the tested parameters of the 4 h and 24 h resuscitation group were significant different (P＜0.05).Conclusion CEUS can quantitatively evaluate the changes of hepatic parenchymal perfusion during HS resuscitation,which has a certain reference for clinical treatment.

Objective To evaluate the left ventricular and right ventricular systolic function by two‐dimensional speckle tracking echocardiography ( 2D‐STE) in patients with rheumatoid arthritis ( RA ) . Methods Fifty five patients with RA and 50 healthy subjects were received echocardiography . 2D‐STE were applied for all the subjects to obtain left ventricular global longitudinal strain ( LVGLS) and right ventricular global longitudinal strain ( RVGLS) .Tricuspid annular plane systolic excursion ( TAPSE) and the change ratio of right ventricular area ( RVACR) were measured by echocardiography . The anti‐cyclic citrullinated peptide antibodies ( anti‐CCP‐II) ,rheumatoid factor ( RF) ,C‐reactive protein ( CRP) and erythrocyte sedimentation rate ( ESR) were detected in both group . The LVGLS and RVGLS in RA group were used to conduce correlation analysis with the level of anti‐CCP‐II ,RF ,CRP , ESR and the duration of disease . Results There was a significant decrease in RVGLS and LVGLS in RA group compared with control group( P <0 .05) . However there was no statistical differenc in TAPSE and RVACR between RA and control group( P > 0 .05) .
