Objective To develop an evaluation index system on health information on the internet using Delphi method. Methods The index system on health information on the internet was drown up and then two rounds of 11 experts' questionnaire consultation were conducted using Delphi method to determine the index system. Results Of 11 experts, the mean age was 48.55±6.79, and 91.67％ of experts had high professional titles and had been working for average (23.64±10.10) years. The altive coefficient for the first and the second hound consultation was 91.67％ and 100.00％ respectively. The average coefficient of specialists authority was 0.75. After two round consultations, Kendalf's concordance coefficients were 0.39 (P<0.01) and 0.51 (P <0.01) , respectively. After two rounds of Delphi, the index system includes 3 from first-level indicators and 15 from secondary-level indicators. Conclusion Experts' representativeness, enthusiasm and professionalism brought to a consensus in developing an evaluation index system to be used in monitoring health information on the internet.

PURPOSE: The aim of this study was to validate a computational fluid dynamics (CFD) simulation of flow-diverter treatment through Doppler ultrasonography measurements in patient-specific models of intracranial bifurcation and side-wall aneurysms. METHODS: Computational and physical models of patient-specific bifurcation and sidewall aneurysms were constructed from computed tomography angiography with use of stereolithography, a three-dimensional printing technology. Flow dynamics parameters before and after flow-diverter treatment were measured with pulse-wave and color Doppler ultrasonography, and then compared with CFD simulations. RESULTS: CFD simulations showed drastic flow reduction after flow-diverter treatment in both aneurysms. The mean volume flow rate decreased by 90% and 85% for the bifurcation aneurysm and the side-wall aneurysm, respectively. Velocity contour plots from computer simulations before and after flow diversion closely resembled the patterns obtained by color Doppler ultrasonography. CONCLUSION: The CFD estimation of flow reduction in aneurysms treated with a flow-diverting stent was verified by Doppler ultrasonography in patient-specific phantom models of bifurcation and side-wall aneurysms. The combination of CFD and ultrasonography may constitute a feasible and reliable technique in studying the treatment of intracranial aneurysms with flow-diverting stents.

Pancreatic cancer is one of the most malignancy tumor in digestive system with extraordinarily poor prognosis owing to its difficulty in early diagnosis and complex treatments.Recently,great progress has been made in surgical techniques,adjuvant treatment and perioperative management of pancreatic cancer.However,the long-term survival of patients with pancreatic cancer has not been significantly improved. American Society of Clinical Oncology released clinical practice guidelines for potentially curable pancreatic cancer in 2016 and updated it for the first time in 2017.In2019,American Society of Clinical Oncology renewed its guidelines in order to modify the program of postoperative adjuvant therapy for pancreatic cancer and recommend FOLFIRINOX as the first choice for postoperative adjuvant therapy for patients with pancreatic cancer in order to improve the prognosis of patients with pancreatic cancer.

Objective:To evaluate the effect of Kinesio taping on chronic nonspecific low back pain (CNLBP). Methods:The Cochrane Library, PubMed, Web of Science, CNKI, CBM, VIP, and Wanfang Data were searched for the randomized controlled trials (RCT) about the effect of Kinesio taping on CNLBP from establishment to January, 2019. The included studies were evaluated according to the method recommended by the Cochrane Collaboration. RevMan 5.3 software was used to analyze the extracted data. Results:Finally, nine RCTs involving 545 patients were included. Meta-analysis showed that the effect of Kinesio taping was significantly different in the improvement of pain compared with the non-stimulated group (MD = -0.76, 95%CI: -1.43 to -0.08, P = 0.03), the difference might be significant compared with the sham stimulation group (MD = -1.10, 95%CI: -2.22 to 0.02, P = 0.05); For improving dysfunction, the Oswestry Disability Index (ODI) scores were better in the Kinesio taping group than in the non-stimulation group (MD = -6.02, 95%CI: -8.63 to -3.41, P < 0.001) and the sham stimulation group (MD = -4.11, 95%CI: -5.82 to -2.41, P < 0.001), however, their was no significant difference in Roland Morris Disability Questionnaire (RMDQ) score between the Kinesio taping group and the non-stimulated group (MD = 0.69, 95%CI: -2.35 to 3.74, P = 0.66), and between the Kinesio taping group and the sham stimulation group (MD = -0.17, 95%CI: -1.43 to 1.08, P = 0.78). Conclusion:For the patients with CNLBP, the intervention of Kinesio taping could alleviate pain and improve function.

Objective: To explore the clinical characteristics of various types of infected pancreatic necrosis(IPN) and the prognosis of different treatment methods in the imaging classification of IPN proposed. Methods: The clinical data of 126 patients with IPN admitted to the Department of Pancreatic and Biliary Surgery, the First Affiliated Hospital of Harbin Medical University from December 2018 to December 2021 were analyzed retrospectively. There were 70 males(55.6%) and 56 females(44.4%), with age(M(IQR)) of 44(17)years (range: 12 to 87 years). There were 67 cases(53.2%) of severe acute pancreatitis and 59 cases (46.8%) of moderately severe acute pancreatitis. All cases were based on the diagnostic criteria of IPN. All cases were divided into Type Ⅰ(central IPN)(n=21), Type Ⅱ(peripheral IPN)(n=23), Type Ⅲ(mixed IPN)(n=74) and Type Ⅳ(isolated IPN)(n=8) according to the different sites of infection and necrosis on CT.According to different treatment strategies,they were divided into Step-up group(n=109) and Step-jump group(n=17). The clinical indicators and prognosis of each group were observed and analyzed by ANOVA,t-test,χ² test or Fisher exact test,respectively. Results: There was no significant difference in mortality, complication rate and complication grade in each type of IPN(all P>0.05). Compared with other types of patients, the length of stay (69(40)days vs. 19(19)days) and hospitalization expenses(323 000(419 000)yuan vs. 60 000(78 000)yuan) were significantly increased in Type Ⅳ IPN(Z=-4.041, -3.972; both P<0.01). The incidence of postoperative residual infection of Type Ⅳ IPN was significantly higher than that of other types (χ²=16.350,P<0.01). There was no significant difference in the mortality of patients with different types of IPN between different treatment groups. The length of stay and hospitalization expenses of patients in the Step-up group were significantly less than those in the Step-jump group(19(20)days vs. 33(35)days, Z=-2.052, P=0.040;59 000(80 000)yuan vs. 122 000(109 000)yuan,Z=-2.317,P=0.020). Among the patients in Type Ⅳ IPN, the hospitalization expenses of Step-up group was significantly higher than that of Step-jump group(330 000(578 000)yuan vs. 141 000 yuan,Z=-2.000,P=0.046). The incidence of postoperative residual infection of Step-up group(17.4%(19/109)) was significantly lower than that of Step-jump group(10/17)(χ²=11.980, P=0.001). Conclusions: Type Ⅳ IPN is more serious than the other three types. It causes longer length of stay and more hospitalization expenses. The step-up approach is safe and effective in the treatment of IPN. However, for infected lesions which are deep in place,difficult to reach by conventional drainage methods, or mainly exhibit "dry necrosis", choosing the step-jump approach is a more positive choice.
