Objective:To understand the cognitive differences and its influential factors of medical dispute and physician′s professionalism between medical personnel and patients, and further to provide evidence for the preven-tion and treatment of medical dispute. Methods:In the case of quality control, we surveyed on the cognitive of medical dispute and physician′s professionalism in medical personnel and patients using self-designed question-naire. Stratified cluster sampling method was used in this study, which recruited 847 medical workers and 577 pa-tients. Data analysis was conducted with SPSS 16. 0. The two sample rates were compared using Chi squaretest (α=0. 05). Results:There is a statistically significance in doctor-patient relationship evaluation, dispute pre-vention, dispute responsibility, fair treatment,impact on the doctors and patients, causes of medical disturbance, attitude tomedical disturbance, medical disturbance elimination, physician′s professionalism evaluation, improve-ment approach, and the physician′s professional value between the two samples, having a direct impact on the con-struction of physician′s professionalism. Conclusion:For medical personnel, they should strengthen the construc-tion of physician′s professionalism and establish effective mechanism to prevent medical dispute. For patienes, they should understand, trust and respect the doctors, and solve medical dispute rationally. For government, they should establish a reasonable mechanism for the settlement of medical dispute, create a rational atmosphere respon-ding to the medical dispute, and reduce the intensification of medical dispute.

Objective To investigate the initial dose and safety of intravenous infusion of sodium (s)-2-(dithiocarboxylato((2R,3R,4R,5R,6R)-2,3,4,5,6-pentahydroxyhexyl) amino)-4-(methylthio) butanoate (GMDTC) for the displacement of cadmium. Methodsi) Efficacy test. The New Zealand male rabbits were randomly divided into model group, calcium disodium edetate (EDTA) group and GMDTC low-, medium- and high-dose groups after cadmium poisoning using 2.5 cadmium chloride dihydrate. Rabbits in EDTA group were intravenously injected with EDTA dipotassium at a dose of 93.5 mg/kg body weight, rabbits in the three doses groups were intravenously injected of GMDTC at doses of 12.0, 36.0, and 108.0 mg/kg body weight, respectively. The rabbits in the control group (separate set) and model group were intravenously injected with equal volumes of 0.9% sodium chloride solution, administered for five consecutive days per week for 1, 2, and 4 weeks. ii) Toxicity test. Specific pathogen free SD rats were randomly divided into solvent control group and low-, medium- and high-dose groups. In the acute toxicity test, the rats in the three-dose groups were intravenously injected of GMDTC at doses of 200.0, 800.0 and 3 000.0 mg/kg body weight, respectively. In the long-term toxicity test, the rats in the three-dose groups were intravenously injected GMDTC at doses of 100.0, 500.0 and 2 000.0 mg/kg body weight, respectively, once a day for four consecutive weeks, with a recovery period of four weeks. The rats in the solvent control group were given an equal volume 0.9% sodium chloride solution intravenously at the same time. The maximum tolerated dose (MTD) and no observable adverse effect level (NOAEL) were detected. Resultsi) In the one week treatment experiment, the 24 hours urinary cadmium levels of rabbits in the three doses groups were higher than those in the model group at the same time point (all P<0.05). In the two weeks treatment experiment, the 24 hours urinary cadmium levels of rabbits in medium-dose and high-dose groups at the three time points were higher than those in the model group at the same time point (all P<0.05). In the four weeks treatment experiment, the 24 hours urinary cadmium level on the 19th day of rabbits in the low-dose group was higher than that in the model group at the same time point (P<0.05), and the 24 hours urinary cadmium levels of rabbits in medium- and high-dose groups at the five time points were higher than those in the model group at the same time point (all P<0.05), except for the rabbits of fifth day of the medium-dose group. The kidney cadmium levels of rabbits in the low-dose group after four week of treatment and in the medium- and high-dose groups after one, two, and four weeks of treatment decreased compared with the model group (all P<0.05). No obvious adverse effects were observed during the treatment. ii) The MTD of GMDTC in rats administered intravenously in a single dose was 3 000.0 mg/kg body weight. During the period of intravenous infuseion with GMDTC for four consecutive weeks, the blood drug level reached the peak at the end of the first and last administrations (eight min), and no clinical adverse reactions were observed during this period of time, nor was there any apparent accumulation. The NOAEL for intravenous infusion of GMDTC for four consecutive weeks in rats was 500.0 mg/kg body weight. Conclusion The initial dose of the GMDTC injection in the cadmium poisoning rabbit was 36.0 mg/kg body weight, and the recommended initial dose for human is 480.0 mg/person. Intravenous infusion of GMDTC is characterized by rapid absorption, rapid elimination, and no accumulation.

Purpose/Significance The paper systematically reviews relevant research on infectious disease prediction models based on internet data,helps to realize the advancement of infectious disease surveillance,and provides references for the construction of intelli-gent three-dimensional prevention and treatment system of infectious diseases.Method/Process The development history and research direction of infectious disease surveillance and early warning based on internet data collected in the core database of Web of Science and CNKI in the past 20 years are reviewed,major existing problems and challenges are analyzed,and common prediction models and their optimization directions are summarized.Result/Conclusion The study on internet infectious disease surveillance shows the trend of diver-sification of monitoring diseases,refinement and specialization of data sources.Due to the complexity and uncertainty of internet data,most of the existing models are only suitable for short-term or real-time prediction.By constructing a combination model,strengthening multi-source data fusion,improving the selection of keywords and influencing factors,the model can be further optimized and the fitting effect and prediction capacity can be strengthened.

【Objective】 To explore the predictive value of preoperative liver function for massive blood transfusion (MBT) in patients undergoing ascending aorta surgery. 【Methods】 Data from 238 patients undergoing ascending aorta surgery in the Department of Cardiovascular Surgery at The Affiliated Lihuili Hospital of Ningbo University were collected. Preoperative liver function tests were performed for all patients. Based on the perioperative transfusion volumes of red blood cell suspension, patients were divided into the MBT group, non-MBT group, and no blood transfusion (NBT) group. Clinical data during the perioperative period were compared among different groups. Receiver operating characteristic curve (ROC curve) analysis was used to assess the predictive value of liver function indicators for MBT and determine cut-off values. 【Results】 Compared with the non-MBT group and NBT group, the MBT group showed statistically significant differences in preoperative levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), direct bilirubin (DBIL), and serum albumin (SA) (P<0.05). ROC curve analysis revealed that AST had the largest area under the curve (AUC) for predicting MBT, with a value of 0.723. ALT had the highest specificity for predicting MBT at 86.7%, and SA had the highest sensitivity at 89.7%. When AST >28.50 U/L, ALT >40.00 U/L, SA ≤34.55 g/L, and DBIL >4.25 μmol/L, there was a significant increase in the transfusion volume of various blood components and the incidence of MBT. 【Conclusion】 Preoperative liver function indicators (AST, ALT, SA, DBIL) have a moderate predictive value for MBT in patients undergoing ascending aorta surgery.
