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.

Objective To investigate the clinical manifesfations and diagnostic and therapeutic features of cholangiocarcinoma associated with hepatolithiasis.Methods The clinical data, the diagnotic and therapeutic featares of 54 cases of cholangiocacinoma associated with hepatolithiasis were retrospectively analyzed.Results The occurrence rate of hepatolithiasis concomitant with hepatocholangiocarcinoma was 11.8%.Due to a lack of specific clinical manifestations, the preoperative diagnosis of this condition was difficult. In this series, the (correct) diagnotic rate of hepatocholangiocarcinoma before operation was only 11.1%. The radical resection rate was 51.8%. Radical resection of the tumor had a better prognosis than that of non-resection of tumor.(Conclusions) Patients with long-term recurrent hepatolithiasis tended to have associated cholangiocarcinoma. Early diagnosis of the disease was difficult, and the treatment results and prognosis were poor. Therefore, (patients) with hepatolithiasis, espesially those with recurrent attacks, should undergo operation early. In cases diagnosed as hepatic cholangioearcinoma at operation, a radical resection should be performed, if possible, and a favorable outcome may be attained.

Objective To explore the protective effects of cannabinoid analogues WIN55212-2 on paraquat poisoned mice. Methods Totally 35 healthy male C57BL/6 mice were randomly(random number) divided into four groups: PQ group (paraquat poisoned, n=10), WIN 1 mg group (PQ+WIN55212-21 mg n=10), WIN 2 mg group (PQ+WIN55212-22 mg, n=10), control group (n=5).The PQ poisoned animal models were established in the PQ group, WIN 1 mg group and WIN 2 mg group by intraperitoneally injection of paraquat with a concentration of 20 mg/kg. Intraperitoneal injection of WIN55212-2 (containing Tween 80 cosolvent) at the concentration of 1 mg/kg and 2 mg/kg was performed 1 h before PQ exposure in the two interfered groups. Equivalent volume of saline was given to the control group. WIN55212-2 was injected twice a week from the second week. In the acute phase (14 d), 5 mice were randomly sacrificed in the PQ group, WIN 1 mg group and WIN 2 mg group, and 3 mice were sacrificed in the control group to obtain blood sample, bronchoalveolar lavage fluid (BALF) and lung tissue. All the remaining mice were executed on day 28, and the tissue samples were collected as mentioned above. HE staining and Masson staining were performed to observe the changes of lung tissues after PQ poisoning. Changes of TNF-α, IL-6 and TGF-β in plasma and BALF were measured by ELISA. Results In the acute phase, the pathological sections of lung tissues in the PQ group, WIN 1 mg group and WIN 2 mg group showed diffuse inflammation, which was improved after the intervention of WIN5522-2, especially in the WIN 1 mg group. IL-6 levels of BALF in the PQ group, WIN 1 mg group, WIN 2 mg group and the control group were (1024.77±124.74)U/L, (620.48±99.76)U/L, (823.29±157.88) U/L, and (180.42±20.22)U/L, respectively. IL-6 levels in the WIN 1 mg group and the WIN 2 mg group were statistically lower than those in the PQ group (P=0.021, P=0.016). However, no difference was found between the two intervention groups(P=0.114). The similar condition was also found in TNF-α in BALF and plasma. In the chronic phase, mice in the PQ group, WIN 1 mg group and WIN 2 mg group showed fibrosis in tissue by HE and Masson staining, and the inflammatory condition was improved after the intervention of WIN5522-2, which was more obvious in the WIN 1 mg group. In BALF, TNF-α level was (321.64±50.54)U/L, (260.23±48.19)U/L, (278.89±29.40)U/L, (89.76 ± 10.87)U/L in the PQ group, WIN 1 mg group, WIN 2 mg group and the control group. Differences were found between the WIN 1 mg group and the control group and the WIN 2 mg group. Similar differences were also observed in plasma TNF-α, but not in TGF-β. Conclusions A small dose of WIN55212-2 can improve the general condition of PQ poisoning mice, and reduce the inflammatory and fibrosis-related cytokines levels in PQ poisoning mice.

Objective:To study the effects of docetaxel, cisplatin and fluorouracil (TPF) regimen simultaneous intensity modulated radiotherapy (IMRT) on immune function and survival prognosis of patients with advanced esophageal cancer.Methods:A total of 93 patients with advanced esophageal cancer were screened in Hebei Veterans General Hospital from June 2015 to December 2017, and were divided into two groups using randomized envelope method. The observation group (47 cases) was given synchronous TPF regimen and IMRT, and the control group (46 cases) was given synchronous PF regimen (cisplatin combined with fluorouracil) and IMRT. Esophageal barium meal, chest and upper abdominal CT were reviewed within 1 month after treatment to assess the short-term efficacy and compare the immune function of the two groups before and after treatment. Kaplan-Meier survival curve was plotted to evaluate the long-term efficacy based on overall survival (OS). The incidence of adverse reactions in the two groups was collected to evaluate their safety.Results:After treatment, the T cell subgroup CD8 + level of the observation group was higher than that of the control group [(33.55±4.46)% vs. (29.06±3.61)%, P<0.05], while CD3 + [(51.29±5.22)% vs. (56.04±6.10)%, P<0.05], CD4 + [(28.27±3.63)% vs. (30.35±3.52)%, P<0.05] and CD4 + /CD8 + (0.84±0.25 vs. 1.04±0.08, P<0.05) levels were lower than those of the control group. The effective rate of recent treatment in the observation group was 82.98% (39/47), while the effective rate in the control group was only 63.04% (29/46), with a statistically significant difference ( χ2=4.70, P=0.030). The median OS of the observation group was 25.3 months (95% CI: 17.9-26.1), and that of the control group was 18.2 months (95% CI: 14.4-25.5), with a statistically significant difference ( χ2=3.28, P=0.038). Adverse reactions during the follow-up period of the two groups of patients were mainly nausea/vomiting, fatigue, anorexia, hematological toxicity, esophagitis and pneumonia, etc., which were mostly grade 1-2, and disappeared after symptomatic treatment or termination of treatment. Compared with the control group, the incidence of nausea/vomiting (46.81% vs. 78.26%, χ2=9.80, P=0.002), anorexia (44.86% vs. 71.74%, χ2=6.99, P=0.008), leukopenia (36.96% vs. 73.91%, χ2=13.37, P<0.001) and esophagitis (61.70% vs. 82.61%, χ2=5.05, P=0.025) adverse reactions was lower in the observation group. Conclusion:TPF combined with IMRT has high efficacy and low adverse reactions, which can be used as an effective treatment to improve the survival prognosis of patients with advanced esophageal cancer.
